TANKER TRUCK WITH REAR LIGHTING ASSEMBLY AND METHOD OF OPERATION

TECHNICAL FIELD

The present disclosure is directed to tank trailers, particularly a rear lighting assembly for tank trailers.

BACKGROUND ART

Tank trailers, liquid tanker trailers, and other similar enclosed trailers serve essential purposes for transporting various types of goods and material, either in solid form, liquid form, or gaseous form, in large quantities. Since these tank trailers are designed to transport large quantities of material, these tank trailers normally have larger footprints and/or surface space as compared to other various types of vehicles on roadways. Given the length and width of these tank trailers, these tank tankers come with various driving obstacles and complications when safety transporting one or more particular goods or materials on roadways, including turning radii of tank trailers, lack of visibility about tank trailers, and other similar obstacles and complications of the like.

To combat against these driving obstacles and complication, conventional tank trailers, liquid tanker trailers, and other similar enclosed trailers include signaling lights to indicate to surrounding drivers and pedestrians driving states or directions of travel of these tank trailers when being towed by vehicles. However, even though signaling lights are beneficial for indicating the direction of travel for a tank trailer, these signaling lights are generally located at limited areas on the rear ends of these tank trailer that could limit visibility of signaling driving states or directions of travel of these tank trailers when being towed. In one instance, these signaling and/or indicating lights may only be placed at a single location at the rear ends of these tank trailers; such location of these signaling lights could be covered by surrounding vehicles physical obstructions placed on or near roadways. In another instance, these signaling lights may only be placed at outer or peripheral locations at the rear ends of these tank trailers; again, such location of these signaling and/or indicating lights could be covered by surrounding vehicles or physical obstructions placed on or near roadways. In yet another instance, these signaling lights may be covered by dirt, road debris, or precipitation given the location at which these lights are located on these tank trailers.

The trailer 1 also has a top end 1E, a bottom end 1F vertically opposite to the top end 1E, and a vertical direction defined therebetween for draining accumulated precipitation, which is described in more detail below.

Still referring to FIG. 1, the trailer 1 may be mechanically connected to a vehicle or towing vehicle, which is generally indicated by the reference number 2. In FIG. 1, the vehicle 2 is a semi-truck mechanically connected to the trailer 1. It will be understood that the illustrated vehicle 2 is exemplary only and any type of vehicle is contemplated to be represented by the illustrated vehicle. Exemplary vehicles considered suitable herein include all-terrain vehicles, cars, sport utility vehicles (SUV), pickup trucks, vans, recreational vehicles, commercial trucks, and any other vehicles of the like used for the purpose of towing a trailer.

Still referring to FIG. 1, the trailer 1 may include a main body 10. The main body 10 may be operably engaged with a frame 3 of the trailer 1. The frame 3 includes at least one wheel and/or tire 4 operably engaged with the frame 3 for suitable moving and transporting the trailer 1 with the vehicle 2. The frame 3 may include any suitable components and/or assemblies for loading and unloading cargo or a load from the main body 10, parking or maintaining the trailer 1 when disconnected from the vehicle 2, providing energy or power to the trailer when disconnected from the vehicle 2, and other suitable components and/or assemblies of the like.

Referring to FIGS. 1 and 2, the main body 10 may have a front end 10A, a rear end 10B longitudinally opposite to the front end 10A, and a longitudinal axis defined therebetween. The main body 10 also has a first side or left side 10C, a second side or right side 10D transversely opposite to the left side 10C, and a transverse axis defined therebetween. The main body 10 also has a top end 10E, a bottom end 10F vertically opposite to the top end 10E, and a vertical axis defined therebetween. The main body 10 also includes a circumferential wall or external wall 12 that extends from the front end 10A to the rear end 10B along the longitudinal axis. The circumferential wall 12 also operably engages with frame 3 for maintaining the main body 10 with the frame 3.

Referring to FIGS. 3B, the main body 10 may include a front bulkhead 14 operably engaged with the circumferential wall 12 at the front end 10A of the main body 10 proximate to the vehicle 2. The main body 10 may also include an opposing rear bulkhead 16 (see FIGS. 3A and 4B-7) operably engaged with the circumferential wall 12 at the rear end 10B of the main body 10. Additionally, the circumferential wall 12, the front bulkhead 14, and the rear bulkhead 16 may collectively define at least one interior chamber 17 that extends from the front bulkhead 14 to the rear bulkhead 16.

The at least one interior chamber 17 may be accessible at various location along the main body 10 for loading cargo into the at least one interior chamber 17 and/or and for unloading cargo from the at least one interior chamber 17. As illustrated in FIG. 1, a piping system “PS” of the trailer 1 may be in fluid communication with the at least one interior chamber 17 of the main body 10 for loading cargo into the at least one interior chamber 17 and for unloading cargo from the at least one interior chamber 17. In other exemplary embodiments, any suitable number of inlets and outlets may be defined in the main body 10 for loading cargo into the at least one interior chamber 17 and for unloading cargo from the at least one interior chamber 17.

While the main body 10 defines at least one interior chamber 17 accessible by the piping system “PS, any suitable number of interior chambers may be defined by the main body and accessible by any suitable number of pipes in a piping system. In one exemplary embodiment, a main body may include an interior bulkhead positioned between a front bulkhead and a rear bulkhead where the main body defines a first interior chamber between the front bulkhead and the interior bulkhead and an exterior chamber between the rear bulkhead and the interior bulkhead. In another exemplary embodiment, a main body may include a plurality of interior bulkheads positioned between a front bulkhead and a rear bulkhead where the main body defines a plurality of interior chambers between each interior bulkhead, the front bulkhead, and the rear bulkhead.

Trailer 1 may include a trough 20 that operably engages with the main body 10 along the top end 10E of the main body 10. In the present disclosure, the trough 20 may extend between the front and rear ends 10A, 10B of the main body 10. In the present disclosure, the trough 20 may also extend beyond the front bulkhead 14 and/or the rear bulkhead 16 of the main body 10, which is described in more detail below.

In the present disclosure, trough 20 may include a front wall 20A, an rear wall 20B longitudinally opposite to the front wall 20A (see FIG. 1), a first side wall or left wall 20C, and second side wall or right wall 20D transversely opposite to the left wall 20C. The trough 20 may define a channel 20E that is collectively defined by the front wall 20A, rear wall 20B, left wall 20C, and right wall 20D. The channel 20E also extends along the entire length of the trough 20 parallel to the longitudinal direction of the trailer 1. The channel 20E defined by the trough 20 may be configured to gather and capture liquid or fluid that enters into the channel 20E. In operation, the trough 20 may be configured to convey rainwater or other forms of precipitation in liquid form from the top end 10E of the main body 10 towards an on-board drainage system for removing the precipitation.

The trough 20 may define a plurality of through-holes 20F at the rear end 10B of the main body 10. As best seen in FIG. 3B, the plurality of through-holes 20F defined by the trough 20 may be configured to receive and house a set of first external brake lights 21A where the set of first external brake lights 21A is operably engaged with the trough 20. In the illustrated embodiment, the set of first external brake lights 21A operably engaged with the trough 20 is used as the third brake light for the trailer 1.

In the present disclosure, trailer 1 may also include a set of second external brake lights 21B. As best seen in FIG. 2, the set of second external brake lights 21B operably engages with frame 3 and is vertically below the main body 10 and the set of first external brake lights 21A. In the illustrated embodiment, the set of second external brake lights 21B, in combination with the set of first external brake lights 21A, is used as the third brake light for the trailer 1.

In the illustrated embodiment, the main body 10 may be made of a first material, which includes the circumferential wall 12, the front bulkhead 14, the rear bulkhead 16, and the trough 20. In the present disclosure, the first material may be a material that is adapted to reflect light emitted from a rear lighting assembly of trailer 1. In one example, the main body 10 may be made from a metal material, specifically aluminum. In another example, the circumferential wall 12, the front bulkhead 14, the rear bulkhead 16, and the trough 20 may each be made from aluminum material. In yet another example, any suitable metal material may be used to make a main body (and its associated components) for a trailer based on various reasons described and illustrated herein.

Trailer 1 may include at least one drainage portion or extension wall 22 that operably engages with the main body 10. More particularly, the extension wall 22 may be a portion of the circumferential wall 12 of the main body 10. As illustrated in FIGS. 3B-4, extension wall 22 of the circumferential wall 12 extends rearwardly away from the rear bulkhead 16 parallel to the longitudinal axis of the trailer 1. In the illustrated embodiment, the circumferential wall 12 and the extension wall 22 is a unibody, monolithic member that is continuous and uninterrupted. In one exemplary embodiment, an extension wall discussed herein may operably engage with a circumferential wall of a main body via attachment mechanisms (e.g., joining mechanisms, fusing mechanisms, welding mechanisms, etc.).

As illustrated in FIG. 3B, the extension wall 22 may include a front end 22A that is proximate to the rear bulkhead 16. Extension wall 22 may also include a rear end 22B that is longitudinally opposite to the front end 22A and is remote and spaced apart from the rear bulkhead 16. The extension wall 22 may also have an inner surface 22C that is defined circumferentially about the extension wall 22. In the present disclosure, the inner surface 22C extends between the front end 22A, proximate to the rear bulkhead 16, and the rear end 22B. The extension wall 22 may also have an outer surface 22D that opposes the inner surface 22C and is defined circumferentially about the extension wall 22. The outer surface 22D may also extend from the front end 22A, proximate to the rear bulkhead 16, to the rear end 22B of the extension wall 22.

Trailer 1 may also include a rear opening 22E that is defined by the rear the exterior wall 22. As best seen in FIG. 3B, the rear opening 22E extends forwardly into the trailer 1 from the rear end 22B of the extension wall 22 to the front end 22A. In the present disclosure, the rear opening 22E is separated from the interior chamber 17 by the rear bulkhead 16 such that the interior chamber 17 and the rear opening 22E are free from fluid communication. As discussed in greater detail below, one or more signaling devices of a rear lighting assembly of trailer 1 may be housed inside of rear opening 22F and be protected from external elements outside the rear opening.

Trailer 1 may include at least one upper drain opening 24 that is defined in extension wall 22 and that extends entirely through the extension wall 22. As illustrated in FIGS. 3B-4, extension wall 22 may define a first upper drain opening 24A and an adjacent second upper drain opening 24B that extend entirely through the extension wall 22 in which the inner surface 22C and the outer surface 22D are in fluid communication with one another through each of the first and second upper drain openings 24A, 24B. As illustrated in FIGS. 3B-4, the first and second upper drain openings 24A, 24B are defined proximate to the top end 10E of the main body 10. The first and second upper drain openings 24A, 24B may also be in fluid communication with the trough 20 due to the first and second upper drain openings 24A, 24B being defined inside of the channel 20E of said trough 20.

The structural configuration of the first and second upper drain openings 24A, 24B and the trough 20 is considered advantageous at least because the first and second upper drain openings 24A, 24B may provide drainage of the accumulated precipitation from the trough 20, through the extension wall 22, and away from the main body 10 and the trailer 1. In one exemplary embodiment, a portion of a trough may be sloped from a medial point of the trough towards a rear drainage portion to suitable drain liquid precipitation away from the main body that is both concealed and isolated from an interior chamber of a main body. Moreover, the first and second upper drain openings 24A, 24B omit additional drainage members (e.g., conduits or pipe members) for draining liquid precipitation to prevent freezing or clogging with frozen precipitation or unwanted debris commonly attributed to drainage members.

Trailer 1 may also include at least one lower drain opening 26 defined in extension wall 22 that extends entirely through the extension wall 22. As illustrated in FIGS. 3B-4, extension wall 22 may include a first lower drain opening 26A and an adjacent second lower drain opening 26B that extend entirely through the extension wall 22 in which the inner surface 22C and the outer surface 22D are in fluid communication with one another at each of the first and second lower drain openings 26A, 26B. As illustrated in FIGS. 3B-4, the first and second lower drain openings 26A, 26B are defined proximate to the bottom end 10F of the main body 10. The first and second lower drain openings 26A, 26B may also be in fluid communication with the trough 20 and the first and second upper drain openings 24A, 24B.

The structural configuration of the first and second lower drain openings 26A, 26B defined by the extension wall 22 is considered advantageous at least because the first and second lower drain openings 26A, 26B may provide drainage of the accumulated precipitation from the trough 20 and away from the main body 10 and the trailer 1. As illustrated in FIGS. 4, the first and second lower drain openings 26A, 26B may be aligned with the first and second upper drain openings 24A, 24B to allow for consistent flow of accumulated precipitation along a vertical axis through each associated upper and lower drain opening. Additionally, the curvature of the extension wall 22 allows the inner surface 22C to act as a funnel to convey any excess fluid to drain towards one or both of the first and second lower drain openings 26A, 26B. Moreover, the first and second lower drain openings 26A, 26B omit additional drainage members (e.g., conduits or pipe members) for draining liquid precipitation to prevent freezing or clogging with frozen precipitation or unwanted debris commonly attributed to drainage members.

While trailer 1 includes trough 20, first and second upper drain openings 24A, 24B, and first and second lower drain openings 26A, 26B, a trailer discussed herein may remove and/or omit one or all of the trough 20, first and second upper drain openings 24A, 24B, and first and second lower drain openings 26A, 26B for various reasons, including the elimination of drainage through extension wall 22.

Trailer 1 may also include at least one divider 30 that operably engages with at least one of the rear bulkhead 16 and extension wall 22. As best seen in FIGS. 3B-4, divider 30 includes a first or front end 30A that operably engages with the rear bulkhead 16 external to the interior chamber 17, and a second or rear end 30B that is opposite to the front end 30A and is spaced apart from the false bulkhead 40. Divider 30 also includes a first side wall 30C that extends transversely between the front end 30A and the rear end 30B, and a second side wall 30D that extends transversely between the front end 30A and the rear end 30B and is opposite to the first side wall 30C. Divider 30 also includes a top end 30E that is positioned vertically above the front end 30A, the rear end 30B, the first side wall 30C, and the second side wall 30D and that operably engages with the extension wall 22, particularly the inner surface 22C of extension wall 22. Divider 30 also includes a bottom end 30F that is positioned vertically below the front end 30A, the rear end 30B, the first side wall 30C, and the second side wall 30D and that operably engages with the extension wall 22, particularly the inner surface 22C of extension wall 22. Such use and purpose of divider 30 is discussed in greater detail below.

In operation, divider 30 provides various uses for trailer 1. In one instance, vertical walls of the divider 30 (i.e., first side wall 30C and second side wall 30D) may act as funnels and/or guides to convey any excess fluid from one or both of the first and second upper drain openings 24A, 24B to one or both of the first and second lower drain openings 26A, 26B. In another instance, the vertical walls of the divider 30 (i.e., first side wall 30C and second side wall 30D) may act as mounting surfaces or points for one or more sets of auxiliary signaling devices of a rear lighting assembly of the trailer 1.

Trailer 1 also includes a mounting wall 32 that operably engages with the extension wall 22. As best seen in FIGS. 3B-4, mounting wall 32 extends radially inwards from the inner surface 22C of the extension wall 22. In the present disclosure, mounting wall 32 includes an outer edge 32A that extends circumferentially about the mounting wall 32 and operably engages with the inner surface 22C of the extension wall 22. Mounting wall 32 also includes an inner edge 32B that extends circumferentially about the mounting wall 32 and is opposite to the outer edge 32A. In the present disclosure, the inner edge 32B is also free from engaging with the extension wall 22. Mounting wall 32 also includes a first or interior surface 32C that extends between the outer edge 32A and the inner edge 32B and faces in a direction towards the rear bulkhead 16. Mounting wall 32 also includes a second or exterior surface 32D that extends between the outer edge 32A and the inner edge 32B and faces in a direction towards the rear end 22B of extension wall 22. In the present disclosure, exterior surface 32D is configured to operably engage with a false bulkhead of trailer 1 that is spaced apart from and positioned rearwardly of the rear bulkhead 16, which is discussed in greater detail below.

Trailer 1 may also include at least one removable false bulkhead 40 that operably engages with at least one of the extension wall 22, the divider 30, and the mounting wall 32. The at least one removable false bulkhead 40 is independent from one or both of the front bulkhead 14 and the rear bulkhead 16 of the main body 10. As best seen in FIGS. 3A-3B, trailer 1 includes a single false bulkhead 40 that operably engages with the extension wall 22 and the mounting wall 32. In the present disclosure, false bulkhead 40 is remote and spaced apart from the rear bulkhead 16 in trailer 1. Stated differently, the false bulkhead 40 is free from engagement with the rear bulkhead 16.

As best seen in FIG. 3B, false bulkhead 40 may include an inner surface 40A facing in a direction towards the rear bulkhead 16 of the main body 10. In the present disclosure, the inner surface 40A is continuous and uninterrupted along the entire surface area of inner surface 40A. False bulkhead 40 may also include an outer surface 40B that faces in a direction away from the rear bulkhead 16 of the main body 10 and opposite to the inner surface 40A. In the present disclosure, the outer surface 40B is also continuous and uninterrupted along the entire surface area of outer surface 40B. In the present disclosure, the inner surface 40A also operably engages with the mounting wall 32, particularly with the exterior surface 32D of mounting wall 32, when trailer 1 is assembled. False bulkhead 40 may also include a surrounding edge 40C that extends circumferential about the false bulkhead 40 and is positioned between the inner surface 40A and the outer surface 40B. In the present disclosure, the surrounding edge 40C also operably engages with the extension wall 22, particularly with the inner surface 22C of extension wall 22, when trailer 1 is assembled.

Upon assembly of trailer 1, false bulkhead 40 is flush or even with the extension wall 22 such that the false bulkhead 40 is observed as the rearmost end of trailer 1 when viewed from a side elevation view (see FIG. 1) or a rear view (see FIGS. 2-3A). More particularly, the outer surface 40B of the false bulkhead 40 is flush or even with the rear end 22B of the extension wall 22 when viewed from a side elevation view or a rear view.

False bulkhead 40 may be adapted to display or provide graphics 42 on the outer surface 40B of the false bulkhead 40 that faces rearwardly away from the trailer 1. As illustrated in FIGS. 2-3A and 5A-7D, the graphics 42 may display any suitable print, engraving, etching, photograph, design, or any other suitable visual art or typographical marking of the like. Such use of the graphics 42 on false bulkhead 40 is considered advantageous at least because the graphics 42 may provide advertising and marketing methods for a company using said false bulkhead assembly 40 on the trailer 1. As such, the graphics 42 may be custom to a specific entity or product that displays a company's or product name, a company's trademark, or any other suitable use for advertising and marketing a specific company or a specific product being hauled in a tank trailer or tank vehicle like trailer 1.

It should be understood that false bulkhead 40 is also made of a second material that is different than the first material of the main body 10 (including circumferential wall 12, front bulkhead 14, and rear bulkhead 16). In the present disclosure, false bulkhead 40 is made of a material that allows light, particularly visible light wavelengths, to pass through the false bulkhead 40 when emitted by a rear lighting assembly of trailer 1, which is discussed in greater detail below.

In one example, false bulkhead 40 may be made of a translucent material, partially or entirely, to diffuse light emitted by a rear lighting assembly of trailer 1 through false bulkhead 40 that obstructs a view of one or more signaling devices of the rear lighting assembly of trailer 1 (see FIGS. 2-3B and FIGS. 5A-5E). In this example, the translucent material may be a polymer or plastic material to diffuse light emitted by a rear lighting assembly of trailer 1 through false bulkhead 40 that obstructs a view of one or more signaling devices of the rear lighting assembly of trailer 1. Upon such light emission, graphics 42 may also be illuminated by the light from the rear lighting assembly of trailer 1 when the light emitted by the rear lighting assembly is brighter than natural light surrounding trailer 1.

In another example, an alternative false bulkhead 40′ may be made of a transparent material, partially or entirely, to transmit light emitted by a rear lighting assembly of trailer 1 through false bulkhead without obstructing a view of one or more signaling devices of the rear lighting assembly of trailer 1 (see FIGS. 6-7E). In this example, the translucent material may be a polymer or plastic material to transmit light emitted by a rear lighting assembly of trailer 1 through false bulkhead 40 without obstructing a view of one or more signaling devices of the rear lighting assembly of trailer 1. Upon such light emission, graphics 42 may also be illuminated by the light from the rear lighting assembly of trailer 1 when the light emitted by the rear lighting assembly is brighter than natural light surrounding trailer 1.

It should also be understood that extension wall 22 may also be made from the first material discussed herein or the second material discussed herein. In the present disclosure, extension wall 22 is made of the first material (as discussed above) that reflect light outwardly towards the false bulkhead 40 when emitted by a rear lighting assembly of trailer 1, which is discussed in greater detail below. In one example, however, extension wall 22 may be made of a translucent material, partially or entirely, to diffuse light emitted by a rear lighting assembly of trailer 1 through false bulkhead 40 that obstructs a view of one or more signaling devices of the rear lighting assembly of trailer 1. In another example, extension wall 22 may be made of a transparent material, partially or entirely, to transmit light emitted by a rear lighting assembly of trailer 1 through false bulkhead 40 without obstructing a view of one or more signaling devices of the rear lighting assembly of trailer 1.

Trailer 1 may also include an exterior chamber 44 collectively defined by the rear bulkhead 16, the extension wall 22, and the false bulkhead 40 when assembled with extension wall 22. In the present disclosure, the exterior chamber 44 is defined from the rear bulkhead 16, along the inner surface 22C of extension wall 22, to the inner surface 40A of the false bulkhead 40. The exterior chamber 44 is also separated from the interior chamber 17 of main body 10 by the rear bulkhead 16; as such, the interior chamber 17 of main body 10 and the exterior chamber 44 are free from being in fluid communication with one another.

Still referring to exterior chamber 44, divider 30 is configured to separate the exterior chamber 44 into a first compartment 44A and a second compartment 44B. As best seen in FIGS. 3B-4, first compartment 44A is collectively defined by the rear bulkhead 16, a first portion of the inner surface 22C of the extension wall 22, the first side wall 30C of the divider 30, and a first portion of the inner surface 40A of false bulkhead 40. Still referring to FIGS. 3B-4, second compartment 44B is collectively defined by the rear bulkhead 16, a second portion of the inner surface 22C of the extension wall 22, the second side wall 30D of the divider 30, and a second portion of the inner surface 40A of false bulkhead 40. As discussed in greater detail below, the divider 30 is configured to separate signaling devices and sets of auxiliary signaling devices of a rear lighting assembly of trailer 1 for signaling driving states and/or directions of travel of trailer 1.

Trailer 1 also includes a rear lighting assembly 50. As discussed in greater detail below, rear lighting assembly 50 is configured to indicate to surrounding drivers and pedestrians the driving states or directions of travel of the trailer 1 along the entire rear end 1B of trailer 1. With such indication, surrounding drivers and pedestrians may clearly see and anticipate the driving states or directions of travel of the trailer 1 when traveling along a roadway. Such components and devices of rear lighting assembly 50 are discussed in greater detail below.

Rear lighting assembly 50 includes at least one turn signaling device 52 that operably engages with one of the rear bulkhead 16 and the false bulkhead 40 and is housed inside of the exterior chamber 44. As best seen in FIGS. 3B-4, rear lighting assembly 50 includes a first turn signaling device 52 that operably engages with the rear bulkhead 16 and is housed inside of the exterior chamber 44. Still referring to FIGS. 3B-4, rear lighting assembly 50 also includes a second turn signaling device 54 that operably engages with the rear bulkhead 16 and is housed inside of the exterior chamber 44. When trailer 1 is towed by vehicle 2, each of the first turn signaling device 52 and the second turn signaling device 54 is configured to emit at least one light signal at the false bulkhead 40 in response to one or more actions made by driver of the vehicle 2; such emission of at least one light signal by one or both of the first turn signaling device 52 and the second turn signaling device 54 is discussed in greater detail below.

In the present disclosure, the first turn signaling device 52 and the second turn signaling device 54 are also separated and spaced apart from the one another by the divider 30. As best seen in FIG. 4, the first turn signaling device 52 is housed inside of the first compartment 44A and the second turn signaling device 54 is housed inside of the second compartment 44B. When trailer 1 is towed by vehicle 2, each of the first turn signaling device 52 and the second turn signaling device 54 is configured to emit at least one light signal inside the first compartment 44A and the second compartment 44B in response to one or more actions made by driver of the vehicle 2 to signal that the trailer 1 and vehicle are turning or traveling in a lateral direction relative to the longitudinal direction of trailer 1 (see FIGS. 5A-5D and 7A-7D); such emission of at least one light signal by one or both of the first turn signaling device 52 and the second turn signaling device 54 is discussed in greater detail below.

It should be understood that while the first turn signaling device 52 and the second turn signaling device 54 are encased inside of the exterior chamber 44 from the external elements that surrounds trailer 1, first turn signaling device 52 and the second turn signaling device 54 may be configured to operate with such external elements. In one instance, first turn signaling device 52 and the second turn signaling device 54 may be configured to operate with such external elements (i.e., dirt, precipitation, and road debris) when the trough 20, the first and second upper drain openings 24A, 24B, and the first and second lower drain openings 26A, 26B are included with trailer 1. As such, the first turn signaling device 52 and the second turn signaling device 54 are sealed and protected from being hindered by dirt, precipitation and/or other debris that enters into the exterior chamber at the first and second upper drain openings 24A, 24B or the first and second lower drain openings 26A, 26B.

Rear lighting assembly 50 also includes a set of first auxiliary or peripheral signaling devices 56. In the present disclosure, the set of first auxiliary signaling devices 56 operably engages with at least one of the extension wall 22 and the divider 30 and is housed inside of the exterior chamber 44, particularly the first compartment 44A. As best seen in FIGS. 3B-4, the set of first auxiliary signaling devices 56 includes a first auxiliary signaling device 56A that operably engages with the inner surface 22C of the extension wall 22 and the first side wall 30C of the divider 30 inside of the first compartment 44A. The set of first auxiliary signaling devices 56 may also include a second auxiliary signaling device 56B and a third auxiliary signaling device 56C that only operably engage with the inner surface 22C of the extension wall 22 inside of the first compartment 44A. During operation, the set of first auxiliary signaling devices 56 may emit one or more light signals in conjunction with the one or more light signals emitted by the first turn signaling device 52.

During operation, the set of second auxiliary signaling devices 58 may emit one or more light signals in conjunction with the one or more light signals emitted by the second signaling device 54.

Examples of suitable numbers of auxiliary signaling devices to be included in a rear lighting assembly include zero, one, at least one, two, three, four, five, and other suitable numbers of auxiliary signaling devices that may be included in a rear lighting assembly as dictated by the implementation.

It should be understood that while the set of second auxiliary signaling devices 58 is encased inside of the exterior chamber 44 from the external elements that surrounds trailer 1, set of second auxiliary signaling devices 58 may be configured to operate with such external elements. In one instance, set of second auxiliary signaling devices 58 may be configured to operate with such external elements (i.e., dirt, precipitation, and road debris) when the trough 20, the first and second upper drain openings 24A, 24B, and the first and second lower drain openings 26A, 26B are included with trailer 1.

Rear lighting assembly 50 may also include at least one reverse signaling device 60 that operably engages with one of the rear bulkhead 16 and the false bulkhead 40 and is housed inside of the exterior chamber 44. As best seen in FIGS. 3B-4, rear lighting assembly 50 includes a first reverse signaling device 60 that operably engages with the rear bulkhead 16 and housed inside of the exterior chamber 44. Still referring to FIGS. 3B-4, rear lighting assembly 50 also includes a second reverse signaling device 62 that operably engages with the rear bulkhead 16 and is housed inside of the exterior chamber 44. When trailer 1 is towed by vehicle 2, each of the first reverse signaling device 60 and the second reverse signaling device 62 is configured to emit at least one light signal at the false bulkhead 40 in response to one or more actions made by driver of the vehicle 2 to signal that the trailer 1 and vehicle 2 are traveling in reverse relative to the longitudinal direction of trailer 1; such emission of at least one light signal by one or both of the first reverse signaling device 60 and the second reverse signaling device 62 is discussed in greater detail below.

In the present disclosure, the first reverse signaling device 60 and the second turn signaling device 62 are also separated and spaced apart from the one another by the divider 30. As best seen in FIG. 4, the first reverse signaling device 60 is housed inside of the first compartment 44A and the second reverse signaling device 62 is housed inside of the second compartment 44B. When trailer 1 is towed by vehicle 2, each of the first reverse signaling device 60 and the second reverse signaling device 62 is configured to emit at least one light signal inside the first compartment 44A and the second compartment 44B in response to one or more actions made by driver of the vehicle 2 (see FIGS. 5E and 7E); such emission of at least one light signal by one or both of the first reverse signaling device 60 and the second reverse signaling device 62 is discussed in greater detail below.

It should be understood that while the first reverse signaling device 60 and the second turn signaling device 62 are encased inside of the exterior chamber 44 from the external elements that surrounds trailer 1, the first reverse signaling device 60 and the second turn signaling device 62 may be configured to operate with such external elements. In one instance, the first reverse signaling device 60 and the second turn signaling device 62 may be configured to operate with such external elements (i.e., dirt, precipitation, and road debris) when the trough 20, the first and second upper drain openings 24A, 24B, and the first and second lower drain openings 26A, 26B are included with trailer 1. As such, the first reverse signaling device 60 and the second turn signaling device 62 are sealed and protected from being hindered by dirt, precipitation and/or other debris that enters into the exterior chamber at the first and second upper drain openings 24A, 24B or the first and second lower drain openings 26A, 26B.

It should be appreciated that while the first reverse signaling device 60 and the second reverse signaling device 62 are configured to signal the trailer 1 and the vehicle 2 are traveling in reverse relative to the longitudinal direction of trailer 1, other signaling devices of rear lighting assembly 50 may be used to signal such reverse traveling. In one instance, the first turn signaling device 52 and the second turn signaling device 54 may be configured to signal that the trailer 1 and the vehicle 2 are traveling in reverse relative to the longitudinal direction of trailer 1 in conjunction with the first reverse signaling device 60 and the second reverse signaling device 62. In this instance, the first turn signaling device 52 and the second turn signaling device 54 may emit a different hue indicator or color of light (i.e., emitting a white light to signal a reverse direction) to signal and/or indicate that the trailer 1 and the vehicle 2 are traveling in reverse relative to the longitudinal direction of trailer 1. In another instance, the first reverse signaling device 60 and the second reverse signaling device 62 may be omitted and the first turn signaling device 52 and the second turn signaling device 54 may be configured to signal that the trailer 1 and the vehicle 2 are traveling in reverse relative to the longitudinal direction of trailer 1. In this instance, the first turn signaling device 52 and the second turn signaling device 54 may emit a different hue indicator or color of light (i.e., emitting white light to signal a reverse direction) to signal and/or indicate that the trailer 1 and the vehicle 2 are traveling in reverse relative to the longitudinal direction of trailer 1.

It should be appreciated that each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62 may be any suitable device that is configured to emit light for signaling the driving states or the directions of travel for trailer 1. In one exemplary embodiment, each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62 may be light emitting diodes (LEDs) that are configured to emit light for signaling the driving states or the directions of travel for trailer 1.

Rear lighting assembly 50 may also include a controller 64. As best seen in FIG. 4, controller 64 is electrically connected with each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62 by a main electrical connection 66. In the present disclosure, the main electrical connection 66 is split into a first electrical connection 66A that electrically connects the first turn signaling device 52 with the controller 64, a second electrical connection 66B that electrically connects the second turn signaling device 54 with the controller 64, a third electrical connection 66C that electrically connects the set of first auxiliary signaling devices 56 with the controller 64, a fourth electrical connection 66D that electrically connects the set of second auxiliary signaling devices 58 with the controller 64, a fifth electrical connection 66E that electrically connects the first reverse signaling device 60 with the controller 64, and a sixth electrical connection 66F that electrically connects the second reverse signaling device 62 with the controller 64. Such electrical connections enables the controller 64 to operate and command one or more of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62 to emit signal lights when initiated by driver of vehicle 2.

In the present disclosure, controller 64 is configured to output one or more signals, via the set of electrical connections 66, to one or more of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62 in response to receiving one or more actions by the driver of vehicle 2. In one example, controller 64 may be provided with trailer 1 and electrically connects with a computer or processing unit of the vehicle 2 to enabling signaling and/or indication of the driving states or directions of travel of the trailer 1 based on one or more actions made by the driver of vehicle 2. In this instance, a second wiring harness 70 (see FIG. 4) may be used to electrically connect the controller 64 with the computer or processing unit of the vehicle 2 to enable electrical communication. In another example, controller 64 may be a computer or processing unit of the vehicle 2 that enables signaling and/or indication of the driving state or direction of travel of the trailer 1 based on one or more actions made by the driver of vehicle 2. In this instance, a wiring harness or electrical connection may be used to electrically connect each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62 with the controller 64 to enable electrical communication.

Rear lighting assembly 50 may also include a power source 68 that operably engages with the controller 64 by an electrical connection 69. In the present disclosure, the power source 68 is located with trailer 1 to provide electrical power to the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, and the second reverse signaling device 62, and the controller 64. In this instance, power source 68 may be a battery or similar device that is capable of storing and outputting electrical energy. In one alternative embodiment, power source 68 may also be at least one battery or electrical storage device that is provide with or preexists on vehicle 2 that provides electrical power to the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, the set of second auxiliary signaling devices 58, the first reverse signaling device 60, the second reverse signaling device 62, and the controller 64.

Having now described the components and devices of trailer 1 that includes rear lighting assembly 50, methods of using the rear lighting assembly 50 when towing trailer 1 with vehicle 2 are described in greater detail below.

Prior to using rear lighting assembly 50, the driver of vehicle 2 mechanically engages the trailer 1 with the vehicle 2 for towing capabilities. Once engaged, the driver of vehicle 2 may then electrically connect the trailer 1 with the vehicle 2 via one or more wiring harnesses 70 provided with trailer 1 to electrically connect the rear lighting assembly 50 with the vehicle 2. Particularly, the driver of vehicle 2 may connect the wiring harness 70 of trailer 1 with a computer or processing unit of vehicle 2 of vehicle 2. Once connected, the rear lighting assembly 50 and the vehicle 2 may then communicate with one another to enable the rear lighting assembly 50 to indicate the driving states or directions of travel of the trailer 1 and the vehicle 2. During operation, the rear lighting assembly 50 indicates various lights to drivers and pedestrians of the driving states or directions of travel of the trailer 1 along the entire rear end 1B of trailer 1. Various lights emitted by the rear lighting assembly 50 through the false bulkhead 40 to indicate the driving states or directions of travel of the trailer 1 are discussed below.

In a first instance, rear lighting assembly 50 may emit a first indicator light 80A through the false bulkhead 40 to indicate running lights for trailer 1. As best seen in FIGS. 5A and 7A, controller 64 may command each of the first turn signaling device 52 and the second turn signaling device 54 to emit the first indicator light 80A through the false bulkhead 40 to indicate running lights for trailer 1. In this instance, the first indicator light 80A is emitted at a first brightness for indicating running lights for trailer 1. Controller 64 may only command each of the first turn signaling device 52 and the second turn signaling device 54 to emit the first indicator light 80A through the false bulkhead 40 when headlights of vehicle 2 are activated by the driver for various reasons, including lack of visibility due to darkness or precipitation experienced by the trailer 1 and vehicle 2. Additionally, the graphics 42 provided on the outer surface 40B of false bulkhead 40 may also be illuminated when each of the first turn signaling device 52 and the second turn signaling device 54 emit the first indicator light 80A through the false bulkhead 40 to indicate running lights for trailer 1; such illumination of the false bulkhead 40 is denoted by shading labeled 41A in FIG. 5A.

In the first instance, it should be appreciated that controller 64 may also command the set of first auxiliary signaling devices 56 and the set of second auxiliary signaling devices 58 to emit the first indicator light 80A in conjunction with the first turn signaling device 52 and the second turn signaling device 54 to indicate running lights for trailer 1. As such, the controller 64 may command each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, and the set of second auxiliary signaling devices 58 to emit the first indicator light 80A through the false bulkhead 40 to indicate running lights for trailer 1. Such light emission by the set of first auxiliary signaling devices 56 and the set of second auxiliary signaling devices 58 enables greater illumination through the false bulkhead 40 to indicate running lights of trailer 1.

In a second instance, rear lighting assembly 50 may emit a second indicator light 80B through the false bulkhead 40 to indicate a first turning direction or first lateral direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. As best seen in FIGS. 5B and 7B, controller 64 may command the first turn signaling device 52 to emit the second indicator light 80B inside of the first compartment 44A and through the false bulkhead 40 to indicate the first turning direction or first lateral direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. In this instance, the second indicator light 80B is emitted at a second brightness that is greater than the first brightness at the first indicator light 80A. Controller 64 may only command the first turn signaling device 52 to emit the second indicator light 80B through the false bulkhead 40 when driver desires to signal that the trailer 1 and vehicle 2 are traveling in the first turning direction or first lateral direction relative to the longitudinal direction of trailer 1; such illumination of a first portion of the false bulkhead 40 is denoted by shading labeled 41B in FIG. 5B. While not illustrated herein, controller 64 may only command the first turn signaling device 52, while leaving the second turn signaling device 54 in an OFF state, to emit the second indicator light 80B through the false bulkhead 40 when driver desires to signal that the trailer 1 and vehicle 2 are traveling in the first turning direction or first lateral direction relative to the longitudinal direction of trailer 1.

In the second instance, it should be appreciated that controller 64 may also command the set of first auxiliary signaling devices 56 to emit the second indicator light 80B to indicate the first turning direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. As such, the controller 64 may command each of the first turn signaling device 52 and the set of first auxiliary signaling devices 56 to emit the second indicator light 80B inside of the first compartment 44A and through the false bulkhead 40 to indicate the first turning direction or first lateral direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. Such light emission by the set of first auxiliary signaling devices 56, in conjunction with the first turn signaling device 52, enables greater illumination through the false bulkhead 40 to indicate the first turning direction to pedestrians and drivers that are positioned behind of the rear end 1B of trailer 1.

In the second instance, it should also be appreciated that controller 64 may also command the first turn signaling device 52 and the set of first auxiliary signaling devices 56 to emit a series of second indicator lights 80B to indicate the first turning direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. Stated differently, controller 64 may command the first turn signaling device 52 and the set of first auxiliary signaling devices 56 to periodically emit or flash the second indicator light 80B to indicate the turning direction to pedestrians and drivers that are positioned behind the rear end 1B of trailer 1.

In the second instance, one or more of the brake lights of the exterior lights 21B below the false bulkhead 40 may emit and flash lights to indicate the first turning direction of the trailer 1 and the vehicle 2. In one instance, two or more brake lights of the exterior lights 21B proximate to the first turn signaling device 52 and the set of first auxiliary signaling lights 56 may be commanded to emit and flash lights to indicate the first turning direction of the trailer 1 and the vehicle 2 in concert with the first turn signaling device 52 and the set of first auxiliary signaling lights 56.

In a third instance, similar to the second instance, rear lighting assembly 50 may emit a third indicator light 80B through the false bulkhead 40 to indicate a second turning direction or second lateral direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1; the second turning direction is opposite to the first turning direction shown in FIGS. 5B and 7B. As best seen in FIGS. 5C and 7C, controller 64 may command the second turn signaling device 54 to emit the third indicator light 80B inside of the second compartment 44B and through the false bulkhead 40 to indicate the second turning direction or second lateral direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1; such illumination of a second portion of the false bulkhead 40 is denoted by shading labeled 41B in FIG. 5C. In this instance, the third indicator light 80B is emitted at a third brightness that is greater than the first brightness of the first indicator light 80A and equal to the second brightness of the second indicator light 80B. Controller 64 may only command the second turn signaling device 54 to emit the third indicator light 80B through the false bulkhead 40 when the driver desires to signal that the trailer 1 and vehicle 2 are traveling in the second turning direction or second lateral direction relative to the longitudinal direction of trailer 1. While not illustrated herein, controller 64 may only command the second turn signaling device 54, while leaving the first turn signaling device 52 in an OFF state, to emit the third indicator light 80B through the false bulkhead 40 when driver desires to signal that the trailer 1 and vehicle 2 are traveling in the second turning direction or second lateral direction relative to the longitudinal direction of trailer 1.

In the third instance, it should be appreciated that controller 64 may also command the set of second auxiliary signaling devices 58 to emit the third indicator light 80B to indicate the second turning direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. As such, the controller 64 may command each of the second turn signaling device 54 and the set of second auxiliary signaling devices 58 to emit the third indicator light 80B inside of the second compartment 44B and through the false bulkhead 40 to indicate the second turning direction or second lateral direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. Such light emission by the set of second auxiliary signaling devices 58, in conjunction with the second turn signaling device 54, enables greater illumination through the false bulkhead 40 to indicate the turning direction to pedestrians and drivers that are positioned behind of the rear end 1B of trailer 1.

In the third instance, it should also be appreciated that controller 64 may also command the second turn signaling device 54 and the set of second auxiliary signaling devices 58 to emit a series of third indicator lights 80B to indicate the second turning direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1. Stated differently, controller 64 may command the second turn signaling device 54 and the set of second auxiliary signaling devices 58 to periodically emit or flash the third indicator light 80B to indicate the turning direction to pedestrians and drivers that are positioned behind the rear end 1B of trailer 1.

In the third instance, one or more of the brake lights of the exterior lights 21B below the false bulkhead 40 may emit and flash lights to indicate the second turning direction of the trailer 1 and the vehicle 2. In one instance, two or more brake lights of the exterior lights 21B proximate to the second turn signaling device 54 and the set of second auxiliary signaling lights 58 may be commanded to emit and flash lights to indicate the second turning direction of the trailer 1 and the vehicle 2 in concert with the second turn signaling device 54 and the set of second auxiliary signaling lights 58.

In a fourth instance, rear lighting assembly 50 may emit a fourth indicator light 80D through the false bulkhead 40 to indicate braking and/or deceleration of the trailer 1 and vehicle 2 in a first longitudinal direction relative to the longitudinal direction of trailer 1. As best seen in FIGS. 5D and 7D, controller 64 may command each of the first turn signaling device 52 and second turn signaling device 54 to emit the fourth indicator light 80D simultaneously through the false bulkhead 40 to indicate the braking and/or deceleration of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1; such illumination of first and second portions of the false bulkhead 40 is denoted by shading labeled 41B in FIG. 5D. In this instance, the fourth indicator light 80D is emitted at a fourth brightness that is greater than the first brightness of the first indicator light 80A and equal to the second brightness of the second indicator light 80B and the third brightness of the third indicator light 80B. Controller 64 may only command the first turn signaling device 52 and second turn signaling device 54 to emit the fourth indicator light 80D through the false bulkhead 40 when the driver initiates a braking action when driving the vehicle 2 to signal that the trailer 1 and vehicle 2 are braking and/or decelerating in the first longitudinal direction relative to the longitudinal direction of trailer 1.

In the fourth instance, it should be appreciated that controller 64 may also command the set of first auxiliary signaling devices 56 and the set of second auxiliary signaling devices 58 to emit the fourth indicator light 80D, in conjunction with the first turn signaling device 52 and the second turn signaling device 54, to indicate braking and/or deceleration of the trailer 1 and vehicle 2 in the first longitudinal direction relative to the longitudinal direction of trailer 1. As such, the controller 64 may command each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, and the set of second auxiliary signaling devices 58 to emit the fourth indicator light 80D through the false bulkhead 40 to indicate braking and/or deceleration of the trailer 1 and vehicle 2 in the first longitudinal direction relative to the longitudinal direction of trailer 1. Such light emission by the set of first auxiliary signaling devices 56 and the set of second auxiliary signaling devices 58 enables greater illumination through the false bulkhead 40 to indicate the braking of the trailer 1 and vehicle 2 to pedestrians and drivers that are positioned behind the rear end 1B of trailer 1.

In the fourth instance, one or more of the brake lights of the exterior lights 21A, 21B above and below the false bulkhead 40 may emit lights to indicate the braking or deceleration of the trailer 1 and the vehicle 2. In one instance, all exterior lights 21A, 21B emit lights to indicate the braking or deceleration of the trailer 1 and the vehicle 2 in concert with the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling lights 56, and the set of second auxiliary signaling lights 58.

In a fifth instance, rear lighting assembly 50 may emit a fifth indicator light 80C through the false bulkhead 40 to indicate a reversing of the trailer 1 and vehicle 2 in a second longitudinal direction relative to the longitudinal direction of trailer 1; the second longitudinal direction is opposite to the first longitudinal direction. As best seen in FIGS. 5E and 7E, controller 64 may command each of the first reverse signaling device 60 and second reverse signaling device 62 to emit the fifth indicator light 80C simultaneously through the false bulkhead 40 to indicate the second longitudinal direction of the trailer 1 and vehicle 2 relative to the longitudinal direction of trailer 1; such illumination of first and second portions of the false bulkhead 40 is denoted by shading labeled 41C in FIG. 5E. In this instance, the fifth indicator light 80C is emitted at a fifth brightness that is greater than the first brightness of the first indicator light 80A and equal to the second brightness of the second indicator light 80B, the third brightness of the third indicator light 80B, and the fourth brightness of the fourth indicator light 80D. Controller 64 may command the first reverse signaling device 60 and second reverse signaling device 62 to emit the fifth indicator light 80C through the false bulkhead 40 when the driver provides the vehicle 2 in a reverse gear so that the trailer 1 and vehicle 2 travel in reverse and/or in the second longitudinal direction.

While not illustrated herein, rear lighting assembly 50 may emit a sixth indicator light through the false bulkhead 40 to indicate traffic hazards experienced by trailer 1 and vehicle 2. In this instance, controller 64 may command each of the first turn signaling device 52 and second turn signaling device 54 the sixth indicator light simultaneously through the false bulkhead 40 to indicate traffic hazards experienced by trailer 1 and vehicle 2. In this instance, the sixth indicator light would be emitted at a sixth brightness that is greater than the first brightness of the first indicator light 80A and equal to the second brightness of the second indicator light 80B, the third brightness of the third indicator light 80B, and the fourth brightness of the fourth indicator light 80D. It should be understood that the sixth indicator light emitted by the first turn signaling device 52 and second turn signaling device 54 are substantially similar to the second indicator light 80B and the third indicator light 80B. Controller 64 may only command the first turn signaling device 52 and second turn signaling device 54 to emit the sixth indicator light through the false bulkhead 40 when the driver actuates a traffic hazards feature inside of vehicle 2.

In the sixth instance, it should be appreciated that controller 64 may also command the set of first auxiliary signaling devices 56 and the set of second auxiliary signaling devices 58 to emit the sixth indicator light, in conjunction with the first turn signaling device 52 and the second turn signaling device 54, to indicate traffic hazards experienced by trailer 1 and vehicle 2. As such, the controller 64 may command each of the first turn signaling device 52, the second turn signaling device 54, the set of first auxiliary signaling devices 56, and the set of second auxiliary signaling devices 58 to emit the sixth indicator light through the false bulkhead 40 to indicate traffic hazards experienced by trailer 1 and vehicle 2. Such light emission by the set of first auxiliary signaling devices 56 and the set of second auxiliary signaling devices 58 enables greater illumination through the false bulkhead 40 to indicate the traffic hazards experienced by trailer 1 and vehicle 2.

An initial step 102 of method 100 includes sending a travel response to a rear lighting assembly of the tank vehicle.

Optional and/or additional steps may be further included in method 100 for signaling a plurality of driving states of a tank vehicle when in travel. An optional step may include that the step of emitting the set of indicating lights through the false bulkhead further includes that the set of indicating lights is transmitted through the false bulkhead free from obstructing a view of the signaling device. An optional step may include that the step of emitting the set of indicating lights through the false bulkhead further includes that the set of indicating lights is diffused through the false bulkhead to obstruct a view of the signaling device. An optional step may further include reflecting at least one indicating light of the set of indicating lights, by a rear bulkhead of the tank vehicle, towards the false bulkhead. Optional steps may include emitting a series of first turn indicating lights of the set of indicating lights, by the signaling device, through the false bulkhead; and signaling a first turning state of the plurality of driving states of the tank vehicle. Optional steps may include emitting a series of second turn indicating lights of the set of indicating lights, by the signaling device, through the false bulkhead; and signaling a second turning state of the plurality of driving states of the tank vehicle; wherein the second turning state is opposite to the first turning state.

In this embodiment, the trailer 200 may include a front end (not shown but similar to front end 1A of trailer 100), a rear end 200B longitudinally opposite to the front end, and a longitudinal direction defined therebetween where the trailer 200 may travel forwardly and backwardly along the longitudinal direction when operably engaged with a towing vehicle. The trailer 200 also has a first side or left side 200C, a second side or right side 200D transversely opposite to the left side 200C, and a transverse direction defined therebetween where the trailer 200 may travel laterally (i.e., turning left and/or right) along the transverse direction when operably engaged with a towing vehicle. The trailer 200 also has a top end 200E, a bottom end 200F vertically opposite to the top end 200E, and a vertical direction defined therebetween for draining accumulated precipitation when trailer 200 is equipped with such drainage systems discussed herein. In this embodiment, however, trailer 200 is not equipped with such drainage systems discussed herein but may include such drainage systems if desired.

Referring to FIG. 9, the trailer 200 may include a main body 210. The main body 210 may operably engage with a frame of the trailer 200 similar to the engagement between the main body 10 and the frame 3 of trailer 1. The main body 210 may have a front end (not illustrated but similar to front end 10A), a rear end 210B longitudinally opposite to the front end, and a longitudinal axis defined therebetween. The main body 210 also has a first side or left side 210C, a second side or right side 210D transversely opposite to the left side 210C, and a transverse axis defined therebetween. The main body 210 also has a top end 210E, a bottom end 210F vertically opposite to the top end 210E, and a vertical axis defined therebetween. The main body 210 also includes a circumferential wall or external wall 212 that extends from the front end to the rear end 210B along the longitudinal axis.

In this embodiment, the main body 210 may include a front bulkhead (not shown) that operably engages with the circumferential wall 212 at the front end of the main body 210 (similar to front bulkhead 14). The main body 210 may also include an opposing rear bulkhead 216 (see FIGS. 10-11) that operably engages with the circumferential wall 212 at the rear end 210B of the main body 210. Additionally, the circumferential wall 212, the front bulkhead, and the rear bulkhead 216 may collectively define at least one interior chamber 217 that extends from the front bulkhead to the rear bulkhead 216.

The at least one interior chamber 217 may be accessible at various location along the main body 210 for loading cargo into the at least one interior chamber 217 and/or and for unloading cargo from the at least one interior chamber 217. In one example, a piping system of trailer 200 (such as piping system “PS” of the trailer 1) may be in fluid communication with the at least one interior chamber 217 of the main body 210 for loading cargo into the at least one interior chamber 217 and for unloading cargo from the at least one interior chamber 217. In other exemplary embodiments, any suitable number of inlets and outlets may be defined in the main body 210 for loading cargo into the at least one interior chamber 217 and for unloading cargo from the at least one interior chamber 217.

While the main body 210 defines at least one interior chamber 217 accessible by the piping system, any suitable number of interior chambers may be defined by the main body and accessible by any suitable number of pipes in a piping system. In one exemplary embodiment, a main body may include an interior bulkhead positioned between a front bulkhead and a rear bulkhead where the main body defines a first interior chamber between the front bulkhead and the interior bulkhead and an exterior chamber between the rear bulkhead and the interior bulkhead. In another exemplary embodiment, a main body may include a plurality of interior bulkheads positioned between a front bulkhead and a rear bulkhead where the main body defines a plurality of interior chambers between each interior bulkhead, the front bulkhead, and the rear bulkhead.

Main body 210 also includes an extension wall 218. As best seen in FIG. 10-10A, extension wall 218 extends rearwardly from the circumferential wall 212 to the rear end 210B of the main body 210. As such, the extension wall 218 is the rearmost part or point of the main body 210. It should be noted that the extension 218 is free from defining the interior chamber 217 of main body 210. As discussed in greater detail below, the extension wall 218 defines an exterior chamber of the trailer 200 along with the rear bulkhead 216.

Main body 210 also includes at least one conduit in the rear bulkhead 216. As best seen in FIG. 11A, main body 210 defines a pair of conduits 219 in the rear bulkhead 216 proximate to the bottom end 210f of main body 210. As discussed in greater detail below, each conduit of the pair of conduits 219 is sized and configured to receive a plurality of wiring harnesses of a rear signaling system of trailer 200. It should be noted though that the cargo loaded inside the interior chamber 217 and the pair of conduits 219 are free from being in fluid communication with one another. As such, cargo loaded inside of the interior chamber 217 is prevented from entering into one or both conduits of the pair of conduits 219.

Trailer 200 also includes a frame or support 220 that operably engages with the main body 210. As best seen in FIGS. 10-10A, frame 220 includes a first or front end 220A that operably engages with the rear bulkhead 216, and a second or rear end 220B that is opposite to the front end 220A and is spaced apart from the rear bulkhead 216. Frame 220 also includes an inner surface 220C that faces into the frame 220, and an outer surface 220D that faces in an opposite direction at the circumferential wall 212. Frame 220 also defines a central opening 220E between the front end 220A and the rear end 220B along the inner surface 220C of frame 220. The central opening 220E is accessible from the rear end 220B of frame 220 when frame 220 is operably engaged with the rear bulkhead 216.

Still referring to FIGS. 10-10A, frame 220 also defines a set of apertures 220F where each aperture of the set of apertures 220F extends entirely through the frame 220 between the inner surface 220C and the outer surface 220D. In this embodiment, the inner surface 220C and the outer surface 220D are in communication with one another at each aperture of the set of apertures 220F. As discussed in greater detail below, the set of apertures 220F is configured to receive a plurality of signaling devices of a rear lighting assembly for indicating one or more directions of travel for trailer 200 when connected to and towed by vehicle 2.

Still referring to FIGS. 10-10A, frame 220 also defines a cable passthrough 220G. Similar to each aperture of the set of apertures 220F, cable passthrough 220G extends entirely through the frame 220 between the inner surface 220C and the outer surface 220D. In this embodiment, the inner surface 220C and the outer surface 220D are in communication with one another at cable passthrough 220G. As discussed in greater detail below, the cable passthrough 220G is configured to receive one or more wiring harnesses that electrically connect to one or more signaling devices mentioned herein.

Trailer 200 also includes a stand 222 that operably engages with the main body 210 and the frame 220. As best seen in FIGS. 10-10A, stand 222 includes a first or top end 222A that operably engages with the frame 220, a second or bottom end 222B that is opposite to the top end 222A and is configured to operably engage with the main body 210. Stand 222 also includes a front wall 222C that operably engages with the rear bulkhead 216, and a rear wall 222D that is spaced apart from the rear bulkhead 216. In this embodiment, stand 222 is positioned at a bottom or lower end of the frame 220 and the bottom end 210f of main body 210 so that stand 222 provides vertical support to the frame 220.

Trailer 200 may also include a divider 230 that operably engages with at least one of the rear bulkhead 216 and frame 220. As best seen in FIG. 10A, divider 230 includes a first or front end 230A that operably engages with the rear bulkhead 216 external to the interior chamber 217, and a second or rear end 230B that is opposite to the front end 230A and is spaced apart from the rear bulkhead 216, which is discussed in greater detail below. Divider 230 also includes a first side wall 230C that extends transversely between the front end 230A and the rear end 230B, and a second side wall 230D that extends transversely between the front end 230A and the rear end 230B and is opposite to the first side wall 230C. Divider 230 also includes a top end 230E that is positioned vertically above the front end 230A, the rear end 230B, the first side wall 230C, and the second side wall 230D and that operably engages with frame 220, particularly the inner surface 220C of frame 220. Divider 230 also includes a bottom end 230F that is positioned vertically below the front end 230A, the rear end 230B, the first side wall 230C, and the second side wall 230D and that operably engages with the frame 220, particularly the inner surface 220C of frame 220. Such use and purpose of divider 230 is discussed in greater detail below. Divider 230 also lies on a vertical axis (denoted as “Y” in FIG. 11) that divides the frame 220 into two portions or compartments, which are discussed in greater detail below.

In operation, divider 230 provides various uses for trailer 200. In one instance, vertical walls of the divider 230 (i.e., first side wall 230C and second side wall 230D) may act as funnels and/or guides to convey any excess fluid from upper drain openings defined in main body 210 (such as upper drain openings 24A, 24B discussed above) to lower drain openings defined in the main body 210 (such as lower drain openings 26A, 26B discussed above). In another instance, the vertical walls of the divider 230 (i.e., first side wall 230C and second side wall 230D) may act as mounting surfaces or points for one or more sets of auxiliary signaling devices of a rear lighting assembly of the trailer 200.

Trailer 200 may also include at least one removable false bulkhead 240 that operably engages with at least one of the main body 210 (particularly the circumferential wall 212), frame 220, the divider 230, and the mounting wall 32. The at least one removable false bulkhead 240 is independent from one or both of the front bulkhead and the rear bulkhead 216 of the main body 210. In this embodiment, and as best seen in FIGS. 9 and 12A-12D, trailer 200 includes a single false bulkhead 240 that operably engages with the circumferential wall 212 of the main body 210. In the present disclosure, false bulkhead 240 is remote and spaced apart from the rear bulkhead 216 in trailer 200. Stated differently, the false bulkhead 240 is free from engaging with the rear bulkhead 216. In other exemplary embodiments, false bulkhead 240 may also operably engage with and/or secure to additional components of trailer 200. In one exemplary embodiment, false bulkhead 240 may operably engage with the circumferential wall 212 of the main body 210 and the frame 220 (particularly the rear end 220B of frame 220).

Upon assembly of trailer 200, false bulkhead 240 is flush or even with the circumferential wall 212 such that the false bulkhead 240 is observed as the rearmost end of trailer 200 when viewed from a side elevation view (see FIG. 9) or a rear view (see FIGS. 12A-12D). More particularly, an outer surface of the false bulkhead 240 is flush or even with the rear end 210B of the main body 210 when viewed from a side elevation view or a rear view.

False bulkhead 240 may be adapted to display or provide graphics 242 on an outer surface 240B of the false bulkhead 240 that faces rearwardly away from the trailer 200. As illustrated in FIGS. 9 and 12A-12D, the graphics 242 may display any suitable print, engraving, etching, photograph, design, or any other suitable visual art or typographical marking of the like. Such use of the graphics 242 on false bulkhead 240 is considered advantageous at least because the graphics 242 may provide advertising and marketing methods for a company using said false bulkhead assembly 240 on the trailer 200. As such, the graphics 242 may be custom to a specific entity or product that displays a company's or product name, a company's trademark, or any other suitable use for advertising and marketing a specific company or a specific product being hauled in a tank trailer or tank vehicle like trailer 200.

It should be understood that false bulkhead 240 is also made of a second material that is different than the first material of the main body 210 (including circumferential wall 212, front bulkhead, and rear bulkhead 216). In the present disclosure, false bulkhead 240 is made of a material that allows light, particularly visible light wavelengths, to pass through the false bulkhead 240 when emitted by a rear lighting assembly of trailer 200, which is discussed in greater detail below.

In one example, false bulkhead 240 may be made of a translucent material, partially or entirely, to diffuse light emitted by a rear lighting assembly of trailer 200 through false bulkhead 240 that obstructs a view of one or more signaling devices of the rear lighting assembly of trailer 200 (see FIGS. 9 and 12A-12D). In this example, the translucent material may be a polymer or plastic material to diffuse light emitted by a rear lighting assembly of trailer 200 through false bulkhead 240 that obstructs a view of one or more signaling devices of the rear lighting assembly of trailer 200. Upon such light emission, graphics 242 may also be illuminated by the light from the rear lighting assembly of trailer 200 when the light emitted by the rear lighting assembly is brighter than natural light surrounding trailer 200.

In another example, an alternative embodiment of false bulkhead 240 may be made of a transparent material, partially or entirely, to transmit light emitted by a rear lighting assembly of trailer 200 through false bulkhead without obstructing a view of one or more signaling devices of the rear lighting assembly of trailer 1 (similar to false bulkhead 40′). In this example, the translucent material may be a polymer or plastic material to transmit light emitted by a rear lighting assembly of trailer 200 through false bulkhead 240 without obstructing a view of one or more signaling devices of the rear lighting assembly of trailer 200.

Trailer 200 may also include an exterior chamber 244 collectively defined by the rear bulkhead 216, the extension wall 218, and the false bulkhead 240 when assembled. In the present disclosure, the exterior chamber 244 is defined from the rear bulkhead 216, along an inner surface of extension wall 218, to an inner surface of the false bulkhead 240. The exterior chamber 244 is also separated from the interior chamber 217 of main body 210 by the rear bulkhead 216; as such, the interior chamber 217 of main body 210 and the exterior chamber 244 are free from being in fluid communication with one another.

Still referring to exterior chamber 244, the frame 220 and the divider 230 are configured to separate the exterior chamber 244 into a first compartment 246A and a second compartment 246B. As best seen in FIG. 11, first compartment 246A is collectively defined by the rear bulkhead 216, a first portion of the extension wall 218, the first side wall 230C of the divider 230, and a first portion of the inner surface of false bulkhead 240. Still referring to FIG. 11, second compartment 246B is collectively defined by the rear bulkhead 216, a second portion of the extension wall 218, the second side wall 230D of the divider 230, and a second portion of the inner surface of false bulkhead 240. As discussed in greater detail below, the divider 230 is configured to separate signaling devices and sets of auxiliary signaling devices of a rear lighting assembly of trailer 200 for signaling driving states and/or directions of travel of trailer 200 to drivers and pedestrians that are traveling behind the trailer 200.

Trailer 200 also includes a travel lighting assembly or rear lighting assembly 250. As discussed in greater detail below, rear lighting assembly 250 is configured to indicate to surrounding drivers and pedestrians the driving states or directions of travel of the trailer 200 along the entire rear end 200B of trailer 200. With such indication, surrounding drivers and pedestrians may clearly see and anticipate the driving states or directions of travel of the trailer 200 when traveling along a roadway. Such components and devices of rear lighting assembly 250 are discussed in greater detail below.

Rear lighting assembly 250 includes a plurality of signaling devices or plurality of turn signaling devices 252 that operably engages with the frame 220 and is housed inside of the exterior chamber 244. As best seen in FIG. 11, rear lighting assembly 250 includes a first group of turn signaling devices 252A that operably engages with the frame 220 and is housed inside of the exterior chamber 244. More particularly, and as best seen in FIG. 11A, the first group of turn signaling devices 252A operably engages with the frame 220 inside of a first group of apertures 220F-1 of the set of apertures 220F that is positioned proximate to the left side 200C of the trailer 200 and inside of the first compartment 246A. Still referring to FIG. 11, rear lighting assembly 250 also includes a second group of turn signaling devices 252B that operably engages with the frame 220 and is housed inside of the exterior chamber 44. More particularly, and as best seen in FIG. 11A, the second group of turn signaling devices 252B operably engages with the frame 220 inside of a second group of apertures 220F-2 of the set of apertures 220F that is positioned proximate to the right side 200D of the trailer 200 and inside of the second compartment 246B. It should be noted that the divider 230 separates the first group of apertures 220F-1 and the second group of apertures 220F-2 of the set of apertures 220F from one another.

When trailer 200 is towed by a vehicle (e.g., vehicle 2), the first group of turn signaling devices 252 and the second group of turn signaling devices 252B may each be commanded to emit a light signal at the false bulkhead 240 in response to one or more actions made by driver of the vehicle 2; such emission of light signals by one or both of the first group of turn signaling devices 252 and the second group of turn signaling devices 252B is discussed in greater detail below.

In the present disclosure, the first group of turn signaling devices 252A and the second group turn signaling devices 252B are also separated and spaced apart from the one another by the divider 230. As best seen in FIG. 11, the first group turn signaling devices 252 is housed inside of the first compartment 246A, and the second group of turn signaling devices 252B is housed inside of the second compartment 246B. When trailer 200 is towed by a vehicle mentioned herein, the first group of turn signaling devices 252 and the second group of turn signaling devices 252B are each configured to emit at least one light signal inside the first compartment 246A and the second compartment 246B in response to one or more actions made by driver of the vehicle to signal that the trailer 200 and vehicle are turning or traveling in a lateral direction relative to the longitudinal direction of trailer 1 (see FIGS. 12A-12D); such emission of at least one light signal by one or both of the first group of turn signaling devices 252 and the second group of turn signaling devices 252B is discussed in greater detail below.

It should be understood that while the first group of turn signaling devices 252 and the second group of turn signaling devices 252B are encased inside of the exterior chamber 244 from the external elements that surrounds trailer 200, first group of turn signaling devices 252 and the second group of turn signaling devices 252B may be configured to operate in external elements. In one instance, first group of turn signaling device 252 and the second group of turn signaling devices 252B may be configured to operate with such external elements (i.e., dirt, precipitation, and road debris) when a trough (e.g., trough 20), first and second upper drain openings (e.g., the first and second upper drain openings 24A, 24B), and first and second lower drain openings (e.g., the first and second lower drain openings 26A, 26B) are included with trailer 200. As such, the first group of turn signaling devices 252 and the second group of turn signaling devices 252B may be sealed and protected from being hindered by dirt, precipitation, and/or other debris that enters into the exterior chamber 244 at the first and second upper drain openings or the first and second lower drain openings.

Rear lighting assembly 250 also includes a set of auxiliary or peripheral signaling devices 254. In the present disclosure, the set of auxiliary signaling devices 254 includes a first auxiliary signaling device 254A that operably engages with the divider 230 and is housed inside of the exterior chamber 244. More particularly, and as best seen in FIG. 11, the first auxiliary signaling devices 254A operably engages with the first side wall 230C of the divider 230 inside of the first compartment 246A. During operation, the first auxiliary signaling devices 254A may emit one or more light signals in conjunction with the one or more light signals emitted by the first group of turn signaling devices 252 inside of the first compartment 246A. The set of auxiliary signaling devices 254 also includes a second auxiliary signaling device 254B that operably engages with the divider 230 and is housed inside of the exterior chamber 244. More particularly, and as best seen in FIG. 11, the second auxiliary signaling device 254B operably engages with the second side wall 230D of the divider 230 inside of the second compartment 246B. During operation, the second auxiliary signaling devices 254B may emit one or more light signals in conjunction with the one or more light signals emitted by the second group of signaling devices 252B inside of the second compartment 246B.

It should be understood that while the set of auxiliary signaling devices 254 is encased inside of the exterior chamber 244 from the external elements that surrounds trailer 200, the set of auxiliary signaling devices 254 may be configured to operate with such external elements. In one instance, set of auxiliary signaling devices 254 may be configured to operate with such external elements (i.e., dirt, precipitation, and road debris) when a trough (e.g., trough 20), first and second upper drain openings (e.g., the first and second upper drain openings 24A, 24B), and first and second lower drain openings (e.g., the first and second lower drain openings 26A, 26B) are included with trailer 200. As such, the set of auxiliary signaling devices 254 may be sealed and protected from being hindered by dirt, precipitation, and/or other debris that enters into the exterior chamber 244 at the first and second upper drain openings or the first and second lower drain openings.

Rear lighting assembly 250 may also include at least one reverse signaling device (e.g., reverse signaling devices 60, 62) that operably engages with one of the rear bulkhead 216 and the false bulkhead 240 and is housed inside of the exterior chamber 244. In one example, rear lighting assembly 250 may include a first reverse signaling device (e.g., first reverse signaling device 60) that operably engages with the rear bulkhead 216 and housed inside of the exterior chamber 244, particularly the first compartment 246A. In this same example, rear lighting assembly 250 may also include a second reverse signaling device (e.g., second reverse signaling device 62) that operably engages with the rear bulkhead 216 and is housed inside of the exterior chamber 244, particularly the second compartment 246B. When trailer 200 is towed by a vehicle, each reverse signaling device may be configured to emit at least one light signal at the false bulkhead 240 in response to one or more actions made by driver of the vehicle to signal that the trailer 200 and vehicle are traveling in reverse relative to the longitudinal direction of trailer 200.

It should be appreciated that other signaling devices of rear lighting assembly 250 may be used to signal such reverse traveling. In one instance, the first group of turn signaling devices 252A and the second group of turn signaling devices 252B may be configured to signal that the trailer 200 and the vehicle are traveling in reverse relative to the longitudinal direction of trailer 200 in conjunction with reverse signaling devices of trailer 200. In this instance, the first group of turn signaling devices 252A and the second group of turn signaling devices 252B may emit a different hue indicator or color of light (i.e., emitting a white light to signal a reverse direction) to signal and/or indicate that the trailer 200 and the vehicle are traveling in reverse relative to the longitudinal direction of trailer 200. In another instance, reverse signaling devices may be omitted and the first group of turn signaling devices 252A and the second group of turn signaling devices 252B may be configured to signal that the trailer 200 and the vehicle are traveling in reverse relative to the longitudinal direction of trailer 200. In this instance, the first group of turn signaling devices 252A and the second group of turn signaling devices 252B may emit a different hue indicator or color of light (i.e., emitting white light to signal a reverse direction) to signal and/or indicate that the trailer 200 and the vehicle are traveling in reverse relative to the longitudinal direction of trailer 200.

It should also be appreciated that each of the set of turn signaling devices 252 and the set of auxiliary signaling devices 254 may be any suitable device that is configured to emit light for signaling the driving states or the directions of travel for trailer 200. In one exemplary embodiment, the set of turn signaling devices 252 and the set of auxiliary signaling devices 254 may be light emitting diodes (LEDs) that are configured to emit light for signaling the driving states or the directions of travel for trailer 200.

Rear lighting assembly 250 may also include a controller 264. As best seen in FIG. 11, controller 264 is electrically connected with each of the first group of turn signaling devices 252A, the second group of turn signaling device 252A, the first auxiliary signaling device 254A, and the second auxiliary signaling device 254B by a plurality of wiring harnesses 266. In the present disclosure, each wiring harness of the plurality of wiring harnesses 266 includes a first electrical connection 266A that is configured to transmit a first signal from the controller 264 so that one or more of the signaling devices 252A, 252B, 254A, 254B emit light at a first brightness or luminance. Each wiring harness of the plurality of wiring harnesses also includes a second electrical connection 266B that is configured to transmit a second signal from the controller 264 so that one or more of the signaling devices 252A, 252B, 254A, 254B emit light at a second brightness or luminance that is greater than the first brightness. As such, the first electrical connection 266A of each wiring harness 266 is configured to transmit a signal at a first amperage, and the second electrical connection 266B of each wiring harness 266 is configured to transmit a signal at a second amperage that is greater than the first amperage. Each wiring harness of the plurality of wiring harnesses 266 also includes a third electrical connection 266C that is used a ground connection when signals are transmitted from the controller 264 to the respective signaling devices 252A, 252B, 254A, 254B.

It should be understood that any commercially-available wiring or electrical connection components may be used for the plurality of wiring harnesses 266. Additionally, any suitable wire gauge may be used for each electrical connections 266A, 266B, 266C of each wiring harness based on the desired amount of electrical current that will be transmitted to the plurality of turn signaling devices 252 and the first and second auxiliary signaling devices 254A, 254B.

In this embodiment, each turn signaling device of the plurality of turn signaling devices 252 are connected with one another, by the plurality of wiring harnesses 266, in a daisy-chain configuration. As such, each turn signaling device of the plurality of turn signaling devices 252 includes a first or receiving wiring harness 267A and a second or transmitting wiring harness 267B in order for each turn signaling device of the plurality of turn signaling devices 252 to receive outputs from the controller 264 based on one or more actions made by the driver of the vehicle to signal and/or indicate the driving state or direction of travel of the trailer 200. In other exemplary embodiments, any suitable electrical connection configuration may be used in order for signaling devices mentioned herein to receive and/or transmit signals for indicating the driving state or direction of travel of the trailer 200 based on one or more actions made by the driver of the vehicle.

As discussed above, controller 264 is configured to output one or more signals, via the plurality of wiring harnesses 266, to one or more of the first group of turn signaling device 252A, the second group of turn signaling devices 252B, the first auxiliary signaling device 254A, and the second auxiliary signaling device 254B in response to receiving one or more actions by the driver of vehicle 2. In one example, controller 264 may be provided with trailer 200 and electrically connects with a computer or processing unit of the vehicle to enabling signaling and/or indication of the driving states or directions of travel of the trailer 200 based on one or more actions made by the driver of vehicle 2. In this instance, a second wiring harness 270 (see FIG. 11) may be used to electrically connect the controller 264 with the computer or processing unit of the vehicle 2 to enable electrical communication. In another example, controller 264 may be a computer or processing unit of the vehicle that enables signaling and/or indication of the driving state or direction of travel of the trailer 200 based on one or more actions made by the driver of vehicle 2. In this instance, a wiring harness or electrical connection may be used to electrically connect each of the first group of turn signaling device 252A, the second group of turn signaling devices 252B, the first auxiliary signaling device 254A, and the second auxiliary signaling device 254B with the controller 264 to enable electrical communication.

Rear lighting assembly 250 may also include a power source 268 that operably engages with the controller 264 by an electrical connection or third wiring harness 269. In the present disclosure, the power source 268 is located with trailer 200 to provide electrical power to the first group of turn signaling device 252A, the second group of turn signaling devices 252B, the first auxiliary signaling device 254A, and the second auxiliary signaling device 254B. In this instance, power source 268 may be a battery or similar device that is capable of storing and outputting electrical energy. In one alternative embodiment, power source 268 may also be at least one battery or electrical storage device that is provided with or preexists on vehicle that provides electrical power to the first group of turn signaling device 252A, the second group of turn signaling devices 252B, the first auxiliary signaling device 254A, the second auxiliary signaling device 254B, and the controller 264.

Having now described the components and devices of trailer 200 that includes rear lighting assembly 250, methods of using the rear lighting assembly 250 when towing trailer 200 with vehicle 2 are described in greater detail below.

Prior to using rear lighting assembly 250, the driver of vehicle 2 mechanically engages the trailer 200 with the vehicle 2 for towing capabilities. Once engaged, the driver of vehicle 2 may then electrically connect the trailer 200 with the vehicle 2 via one or more wiring harnesses 270 provided with trailer 200 to electrically connect the rear lighting assembly 250 with the vehicle 2. Particularly, the driver of vehicle 2 may connect the wiring harness 270 of trailer 200 with a computer or processing unit of vehicle 2. Once connected, the rear lighting assembly 250 and the vehicle 2 may then communicate with one another to enable the rear lighting assembly 250 to indicate the driving states or directions of travel of the trailer 200 and the vehicle 2. During operation, the rear lighting assembly 250 indicates various lights of driving states or directions of travel of the trailer 200 along the entire rear end 200B of trailer 200 to nearby drivers and pedestrians that are traveling near or behind trailer 200. Various lights emitted by the rear lighting assembly 250 through the false bulkhead 240 to indicate the driving states or directions of travel of the trailer 200 are now discussed below.

In a first instance, rear lighting assembly 250 may emit a first indicator light 280A through the false bulkhead 240 to indicate running lights for trailer 200. As best seen in FIG. 12A, controller 264 may command each of the first group of turn signaling device 252A and the second group of turn signaling device 252B to emit the first indicator light 280A through the false bulkhead 240 to indicate running lights for trailer 200. In this instance, the first indicator light 280A is emitted at a first brightness for indicating running lights for trailer 200. As such, controller 264 transmits a first signal having a first amperage to the first group of turn signaling device 252A and the second group of turn signaling device 252B to emit the first indicator light 280A via the first electrical connection 266A of each wiring harness 266. Controller 264 may only command each of the first group of turn signaling devices 252A and the second group of turn signaling device 252B to emit the first indicator light 280A through the false bulkhead 240 when headlights of vehicle 2 are activated by the driver for various reasons, including lack of visibility due to darkness or precipitation experienced by the trailer 200 and vehicle 2. Additionally, the graphics 242 provided on the false bulkhead 240 may also be illuminated when the first group of turn signaling devices 252A and the second group of turn signaling device 252B emit the first indicator light 280A through the false bulkhead 240 to indicate running lights for trailer 200.

In the first instance, it should be appreciated that controller 264 may also command the set of auxiliary signaling devices 254 to emit the first indicator light 280A in conjunction with the first group of turn signaling devices 252A and the second group of turn signaling device 252B to indicate running lights for trailer 200. As such, the controller 264 may output a first signal to command first group of turn signaling devices 252A, the second group of turn signaling device 252B, and the set of auxiliary signaling devices 254 to emit the first indicator light 280A through the false bulkhead 240 to indicate running lights for trailer 200. Such light emission by the set of auxiliary signaling devices 254 may enable greater illumination through the false bulkhead 240 to indicate running lights of trailer 200. It should be noted that such first signal outputted by the controller 264 to the first group of turn signaling devices 252A, the second group of turn signaling device 252B, and the set of auxiliary signaling devices 254 is transmitted along the first electrical connection 266A of each wiring harness 260 since this first signal is transmitted at a first amperage and is compatible with the first electrical connection 266A.

In a second instance, rear lighting assembly 250 may emit a second indicator light 280B through the false bulkhead 240 to indicate a first turning direction or first lateral direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. As best seen in FIG. 12B, controller 264 may command the first group of turn signaling devices 252A to emit the second indicator light 280B inside of the first compartment 246A and through the false bulkhead 240 to indicate the first turning direction or first lateral direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. In this instance, the second indicator light 280B is emitted at a second brightness that is greater than the first brightness at the first indicator light 280A. Particularly, controller 264 transmits a second signal to the first group of turn signaling device 252A to emit the second indicator light 280B via the second electrical connection 266B of each wiring harness 266. As such, the second signal has a second amperage that is greater than the first amperage of the first signal so that the second indicator light 280B emitted by the first group of turn signaling devices 252A is at a greater brightness than the first indicator light 280A being emitted only by the second group of turn signals devices 252B.

Controller 264 may only command the first group of turn signaling devices 252A to emit the second indicator light 280B through the false bulkhead 240 when driver desires to signal that the trailer 200 and vehicle 2 are traveling in the first turning direction or first lateral direction relative to the longitudinal direction of trailer 200. While not illustrated herein, controller 264 may only command the first group of turn signaling devices 252, while leaving the second group of turn signaling devices 252B in an OFF state, to emit the second indicator light 280B through the false bulkhead 240 when driver desires to signal that the trailer 200 and vehicle 2 are traveling in the first turning direction or first lateral direction relative to the longitudinal direction of trailer 200. Such state may be desirable when the driver is operating the trailer 200 and vehicle in daylight conditions and the running lights are not needed.

In the second instance, it should be appreciated that controller 264 may also command the set of auxiliary signaling devices 254 to emit the second indicator light 280B to indicate the first turning direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. As such, the controller 264 may command the first group of turn signaling devices 252A and the first auxiliary signaling device 254A to emit the second indicator light 280B inside of the first compartment 246A and through the false bulkhead 240 to indicate the first turning direction or first lateral direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. Such light emission by the first auxiliary signaling device 254A, in conjunction with the first group of turn signaling devices 252A, may enable greater illumination through the false bulkhead 240 to indicate the first turning direction to pedestrians and drivers that are positioned behind of the rear end 200B of trailer 200. It should be noted that the second signal outputted by the controller 264 is received identically as to how the first group of turn signaling devices 252A received the second signal from the controller 264 (i.e., via the second electrical connection 266B of wiring harness 266).

In a third instance, rear lighting assembly 250 may emit a third indicator light 280C through the false bulkhead 240 to indicate a second turning direction or second lateral direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. As best seen in FIG. 12C, controller 264 may command the second group of turn signaling devices 252B to emit the third indicator light 280C inside of the second compartment 244C and through the false bulkhead 240 to indicate the second turning direction or second lateral direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. In this instance, the third indicator light 280C is emitted at a second brightness that is greater than the first brightness at the first indicator light 280A. Particularly, controller 264 transmits a second signal to the second group of turn signaling device 252B to emit the third indicator light 280C via the second electrical connection 266B of each wiring harness 266. As such, the second signal has a second amperage that is greater than the first amperage of the first signal so that the third indicator light 280C emitted by the second group of turn signaling devices 252B is at a greater brightness than the first indicator light 280A being emitted only by the first group of turn signals devices 252A.

Controller 264 may only command the second group of turn signaling devices 252B to emit the third indicator light 280C through the false bulkhead 240 when driver desires to signal that the trailer 200 and vehicle 2 are traveling in the second turning direction or second lateral direction relative to the longitudinal direction of trailer 200. While not illustrated herein, controller 264 may only command the second group of turn signaling devices 252, while leaving the first group of turn signaling devices 252A in an OFF state, to emit the third indicator light 280C through the false bulkhead 240 when driver desires to signal that the trailer 200 and vehicle 2 are traveling in the second turning direction or second lateral direction relative to the longitudinal direction of trailer 200. Such state may be desirable when the driver is operating the trailer 200 and vehicle in daylight conditions and the running lights are not needed.

In the third instance, it should be appreciated that controller 264 may also command the set of auxiliary signaling devices 254 to emit the third indicator light 280C to indicate the second turning direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. As such, the controller 264 may command the second group of turn signaling devices 252B and the second auxiliary signaling device 254B to emit the third indicator light 280C inside of the second compartment 246B and through the false bulkhead 240 to indicate the second turning direction or second lateral direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. Such light emission by the second auxiliary signaling device 254B, in conjunction with the second group of turn signaling devices 252B, may enable greater illumination through the false bulkhead 240 to indicate the second turning direction to pedestrians and drivers that are positioned behind of the rear end 200B of trailer 200. It should be noted that the second signal outputted by the controller 264 is received identically as to how the first group of turn signaling devices 252A received the second signal from the controller 264 (i.e., via the second electrical connection 266B of wiring harness 266).

In a fourth instance, rear lighting assembly 250 may emit a fourth indicator light 280D through the false bulkhead 240 to indicate braking and/or deceleration of the trailer 200 and vehicle 2 in a first longitudinal direction relative to the longitudinal direction of trailer 200. As best seen in FIG. 12D, controller 264 may command the first group of turn signaling devices 252A and second group of turn signaling devices 252A to emit the fourth indicator light 280D simultaneously through the false bulkhead 240 to indicate the braking and/or deceleration of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 1; such illumination of first and second portions of the false bulkhead 240 is shown in FIG. 12D. In this instance, the fourth indicator light 280D is emitted at a fourth brightness that is greater than the first brightness of the first indicator light 280A and equal to the second brightness of the second indicator light 280B and the third brightness of the third indicator light 280C. Particularly, controller 264 transmits a third signal to the first and second groups of turn signaling device 252A, 252B to emit the fourth indicator light 280D via the second electrical connections 266B of the wiring harnesses 266. As such, the third signal has a second amperage that is greater than the first amperage of the first signal so that the fourth indicator light 280D emitted by the first and second groups of turn signaling devices 252A, 252B is at a greater brightness than the first indicator light 280A discussed previously. Controller 264 may only command the first group of turn signaling devices 252A and second group of turn signaling devices 252B to emit the fourth indicator light 280D through the false bulkhead 240 when the driver initiates a braking action when driving the vehicle 2 to signal that the trailer 200 and vehicle 2 are braking and/or decelerating in the first longitudinal direction relative to the longitudinal direction of trailer 200.

In the fourth instance, it should be appreciated that controller 264 may also command the set of auxiliary signaling devices 254 to emit the fourth indicator light 280D, in conjunction with the first group of turn signaling devices 252A and the second group of turn signaling devices 252B, to indicate braking and/or deceleration of the trailer 200 and vehicle 2 in the first longitudinal direction relative to the longitudinal direction of trailer 1. As such, the controller 64 may command each of the first group of turn signaling devices 252A, the second group of turn signaling devices 252B, and set of auxiliary signaling devices 254 to emit the fourth indicator light 280D through the false bulkhead 240 to indicate braking and/or deceleration of the trailer 200 and vehicle 2 in the first longitudinal direction relative to the longitudinal direction of trailer 200. Such light emission by the set of auxiliary signaling devices 254 may enable greater illumination through the false bulkhead 240 to indicate the braking of the trailer 200 and vehicle 2 to pedestrians and drivers that are positioned behind the rear end 200B of trailer 200. It should be noted that the third signal outputted by the controller 264 is received identically as to how the first and second groups of turn signaling devices 252A, 252B received the third signal from the controller 264 (i.e., via the second electrical connection 266B of wiring harness 266).

While not illustrated in this embodiment, rear lighting assembly 250 may emit a fifth indicator light through the false bulkhead 40 to indicate a reversing of the trailer 200 and vehicle 2 in a second longitudinal direction relative to the longitudinal direction of trailer 1; the second longitudinal direction is opposite to the first longitudinal direction. Similar to FIG. 5E, controller 264 may command reverse signaling devices of trailer 200 or the plurality of signaling devices 252 to emit the fifth indicator light simultaneously through the false bulkhead 240 to indicate the second longitudinal direction of the trailer 200 and vehicle 2 relative to the longitudinal direction of trailer 200. In this instance, the fifth indicator light is emitted at a fifth brightness that is greater than the first brightness of the first indicator light 280A and equal to the second brightness of the second indicator light 280B, the third brightness of the third indicator light 280C, and the fourth brightness of the fourth indicator light 280D. Controller 264 may command reverse signaling devices of trailer 200 or the plurality of signaling devices 252 to emit the fifth indicator light through the false bulkhead 240 when the driver provides the vehicle 2 in a reverse gear so that the trailer 200 and vehicle 2 travel in reverse and/or in the second longitudinal direction.

FIG. 13 illustrate another trailer 300 that is similar to trailer 200 discussed above and illustrated in FIGS. 9-12D.

In this embodiment, trailer 300 includes a main body 310 having a front bulkhead (not illustrated) and a rear bulkhead 316. Trailer 300 also includes a frame 320 and a stand 322 that operably engage with the main body 310; the frame 320 and the stand 322 are substantially similar to the frame 220 and the stand 222 of trailer 200. Additionally, trailer 300 also includes a divider 330 that is similar to divider 230 of trailer 200. Here, divider 330 includes a first end 330A, a second end 330B, a first side wall 330C, a second side wall 330D, a top end 330E, and a bottom end 330F that are identical to the first end 230A, second end 230B, first side wall 230C, second side wall 230D, top end 230E, and bottom end 230F of divider 230 of trailer 200. However, in this embodiment, divider 330 defines a set of openings 330G that extends between the first side wall 330C and the second side wall 330D; the first side wall 330C and the second side wall 330D are in communication with one another at each opening of the set of openings 330G. Such use and purpose of the set of openings 330G is discussed in greater detail below.

Trailer 300 also defines an exterior chamber 344 collectively by the rear bulkhead 316 of the trailer 300, the frame 320, and a false bulkhead (not shown but identical to false bulkhead 240) of the trailer 300 similar to exterior chamber 244 of trailer 200.

In this embodiment, however, the plurality of turn signaling devices 352 includes a third group of turn signaling devices 352C and a fourth group of turn signaling devices 352D that operably engage with the divider 330 inside of the set of openings 330G. Particularly, the third group of turn signaling devices 352C is seated inside of a first group of openings 330G-1 of the set of openings 330G to operably engage with the divider 330 (see FIG. 13). Additionally, the fourth group of turn signaling devices 352D is seated inside of a second group of openings 330G-2 of the set of openings 330G to operably engage with the divider 330 (see FIG. 13). In this configuration, the third group of turn signaling devices 352C face in a first direction into the first compartment 346A, and the fourth group of turn signaling devices 352D face in an opposing second direction into the second compartment 346B. In operation, the third group of turn signaling devices 352C may work in conjunction with the first group of turn signaling devices 352A to illuminate the first compartment 346A so that a first portion of the false bulkhead is illuminated for indicate a direction of travel for trailer 300 to drivers and pedestrians traveling near or behind trailer 300. Similarly, in operation, the fourth group of turn signaling devices 352D may work in conjunction with the second group of turn signaling devices 352B to illuminate the second compartment 346B so that a second portion of the false bulkhead is illuminated for indicate a direction of travel for trailer 300 to drivers and pedestrians traveling near or behind trailer 300.

Rear signaling system 350 also includes a plurality of wiring harnesses 366 that are identical to the plurality of wiring harnesses 266 of the rear signaling system 250. In this embodiment, the plurality of wiring harnesses 366 electrically connect the plurality of turn signaling devices 252 to a controller of the rear signaling system 350. It should be noted that the controller of the rear signaling system 350 may be any suitable controller discussed herein, including controller 264 of rear signaling system 250. It should also be noted that the controller of the rear signaling system 350 also connects to an on-board power supply of trailer 300 and the vehicle that is towing trailer 300 to operate and to output various signals to the plurality of turn signaling devices 352 to signal or indicate the direction of travel of the trailer 300 and the vehicle.

FIG. 14 illustrates an alternative trailer 200′ of the trailer 200 discussed above and shown in FIGS. 9-12D. As such, trailer 200′ includes a main body 210′, a frame 220′, a divider 230′, a travel signaling system 250′ that includes a set of plurality of turn signaling devices 252′ divided in first and second groups of turn signaling devices 252A′, 252B′, and a set of auxiliary signaling devices 254′ divided into first and second auxiliary signaling devices 254A′, 254B′ similar to main body 210, frame 220, divider 230, travel signaling system 250 that includes the set of plurality of turn signaling devices 252 divided in first and second groups of turn signaling devices 252A, 252B, and the set of auxiliary signaling devices 254 divided into first and second auxiliary signaling devices 254A, 254B. In this alternative embodiment, however, the alternative trailer 200′ defines an ovoidal two-dimensional cross-sectional shape when viewed from a rear elevation view (see FIG. 14). As such, the alternative trailer 200′ is similar to the trailer 200 (as discussed above) except for the differences between two-dimensional cross-sectional shape of trailer 200 and trailer 200′.

Additionally, trailer 200′ may include a drainage system similar to the drainage system discussed in trailer 1 and shown in FIGS. 1-7. As such, trailer 200′ may include a trough, a drainage wall or extension wall, at least one upper drain opening defined in the drainage wall, and at least one lower drain opening defined in the drainage wall similar to the trough 20, drainage wall 22, at least one upper drain opening 24 defined in the drainage wall 22, and at least one lower drain opening 26 defined in the drainage wall 22.

In this embodiment, trailer 400 includes a main body 410 that has an extension wall 418 that extends beyond a rear bulkhead 416 of main body 410. As best seen in FIG. 16, the extension wall 418 includes an interior surface 418A and an exterior surface 418B that faces away from the interior surface 418A and is in communication with the exterior environment surrounding the trailer 400. Extension wall 418 also includes a terminal or rear end 418C that is rearmost point of the main body 410. It should be noted that the main body 410 of the trailer 400 defines a different cross-sectional shape than the main body 310 of the trailer 300 shown in FIG. 13. In this embodiment, the main body 410 of trailer 400 defines an ovoidal two-dimensional cross-sectional shape when viewed from a rear elevation view (see FIG. 15).

In this same embodiment, trailer 400 includes a frame 420 that operably engages with the main body 410 of trailer 400, particularly the extension wall 418 of main body 410. As best seen in FIG. 16, the frame 420 includes a base 422 that operably engages with and extends outwardly from the extension wall 418 at the interior surface 418A. In this embodiment, the base 422 extends along an axis that is non-parallel to a longitudinal axis of the extension wall 418. More particularly, the base 422 extends along an axis that is orthogonal to the longitudinal axis of the extension wall 418. While not illustrated herein, a false bulkhead of the trailer 400 may be configured to engage with the base 422 along with other components of the trailer 400, including extension wall 418.

The frame 420 also includes a plurality of arms 423 that extends outwardly from the base 422. As best seen in FIG. 16, each arm of the plurality of arms 423 includes an outer surface 423A that faces away from the extension wall 418, and an inner surface 423B that is opposite to the outer surface 423A and faces at the extension wall 418. Each arm of the plurality of arms 423 also defines an aperture 423C that extends entirely through the arm 423 between the outer surface 423A and the inner surface 423B; the outer surface 423A and the inner surface 423B of each arm of the plurality of arms 423 are in communication with one another at the corresponding aperture 423C.

Still referring to frame 420, each arm of the plurality of arms 423 is also positioned at an angle that is non-parallel to the base 422 of the frame 420. In this embodiment, each arm of the plurality of arms 423 is defined at an angle 423D that is measured between the inner surface 423B of each arm of the plurality of arms 423 to the inner surface of the base 422; such angle for each arm of the plurality of arms 423 is denoted by a double arrow labeled 423D in FIG. 16. In this embodiment, the angle 423D of each arm of the plurality of arms 423 is defined at approximately 90 degrees measured between the inner surface 423B of each arm of the plurality of arms 423 and the inner surface of the base 422 such that each arm of the plurality of arms 423 is substantially perpendicular to and/or orthogonal to the base 422. Additionally, each arm of the plurality of arms 423 is also defined substantially parallel to the extension wall 418 of the main body 410 measured between the inner surface 423B of each arm of the plurality of arms 423 and the extension wall 418.

In this embodiment, the base 422 and the plurality of arms 423 are integrally formed with one another such that the base 422 and the plurality of arms 423 form a single, monolithic frame 420 for trailer 400. As such, each arm of the plurality of arms 423 is bent to the angle 423D discussed above. In other exemplary embodiments, any suitable techniques or procedures of attaching or securing the base 422 and the plurality of arms 423 with one another may be used when the base 422 and the plurality of arms 423 are separate components from one another. In one example, the base 422 and the plurality of arms 423 may be welded and/or bonded together to form a single, monolithic frame 420 for trailer 400 in which each arm of the plurality of arms 423 is maintained at the angle 423D.

Trailer 400 also includes a divider 430 that operably engages with the rear bulkhead 416 and the frame 420. In this embodiment, the divider 430 is substantially similar to the divider 330 of trailer 300 mentioned above and illustrated in FIG. 13. As such, divider 430 includes a first end 430A, a second end 430B, a first side wall 430C, a second side wall 430D, a top end 430E, a bottom end 430F, and a set of openings 430G that are substantially similar to first end 330A, second end 330B, first side wall 330C, second side wall 330D, top end 330E, bottom end 330F, and set of openings 330G of divider 330.

Trailer 400 also defines an exterior chamber 444 collectively by the rear bulkhead 416 of the trailer 400, the frame 420, and a false bulkhead (not shown but similar to false bulkhead 40) of the trailer 400 similar to exterior chamber 244 of trailer 200. Trailer 400 also defines a first compartment 446A by a first portion of the rear bulkhead 416, a first portion of the frame 420, and the first side wall 430C of the divider 430 similar to the first compartment 46A of trailer 1.

Additionally, each arm of the second plurality of arms 623 is also defined substantially parallel to the extension wall 618 of the main body 610 measured between the inner surface 623B of each arm of the second plurality of arms 623 and the extension wall 618. Since the extension wall 618 and the base 621 are parallel to one another, the angle 622D measured between the base 621 and each arm of the second plurality of arms 623 is the same when measured between the extension wall 618 and each arm of the second plurality of arms 623.

In this embodiment, the base 621, the first plurality of arms 622, and the second plurality of arms 623 are integrally formed with one another such that the base 621 and the first and second pluralities of arms 622, 623 form a single, monolithic frame 420 for trailer 400. As such, each arm of the first plurality of arms 622 and each arm of the second plurality of arms 623 may be bent to the angles 622D, 623D discussed above. In other exemplary embodiments, any suitable techniques or procedures of attaching the base 621 and the first and second pluralities of arms 622, 623 with one another may be used when the base 621 and the first and second pluralities of arms 622, 623 are separate components from one another.

As described herein, aspects of the present disclosure may include one or more electrical, pneumatic, hydraulic, or other similar secondary components and/or systems therein. The present disclosure is therefore contemplated and will be understood to include any necessary operational components thereof. For example, electrical components will be understood to include any suitable and necessary wiring, fuses, or the like for normal operation thereof. Similarly, any pneumatic systems provided may include any secondary or peripheral components such as air hoses, compressors, valves, meters, or the like. It will be further understood that any connections between various components not explicitly described herein may be made through any suitable means including mechanical fasteners, or more permanent attachment means, such as welding or the like. Alternatively, where feasible and/or desirable, various components of the present disclosure may be integrally formed as a single unit.

Various inventive concepts may be embodied as one or more methods, of which an example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.

While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

The above-described embodiments can be implemented in any of numerous ways. For example, embodiments of technology disclosed herein may be implemented using hardware, software, or a combination thereof. When implemented in software, the software code or instructions can be executed on any suitable processor or collection of processors, whether provided in a single computer or distributed among multiple computers. Furthermore, the instructions or software code can be stored in at least one non-transitory computer readable storage medium.

The articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims (if at all), should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

While components of the present disclosure are described herein in relation to each other, it is possible for one of the components disclosed herein to include inventive subject matter, if claimed alone or used alone. In keeping with the above example, if the disclosed embodiments teach the features of A and B, then there may be inventive subject matter in the combination of A and B, A alone, or B alone, unless otherwise stated herein.

As used herein in the specification and in the claims, the term “effecting” or a phrase or claim element beginning with the term “effecting” should be understood to mean to cause something to happen or to bring something about. For example, effecting an event to occur may be caused by actions of a first party even though a second party actually performed the event or had the event occur to the second party. Stated otherwise, effecting refers to one party giving another party the tools, objects, or resources to cause an event to occur. Thus, in this example a claim element of “effecting an event to occur” would mean that a first party is giving a second party the tools or resources needed for the second party to perform the event, however the affirmative single action is the responsibility of the first party to provide the tools or resources to cause said event to occur.

When a feature or element is herein referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.

Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper”, “above”, “behind”, “in front of”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”, “lateral”, “transverse”, “longitudinal”, and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

Although the terms “first” and “second” may be used herein to describe various features/elements, these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed herein could be termed a second feature/element, and similarly, a second feature/element discussed herein could be termed a first feature/element without departing from the teachings of the present invention.

An embodiment is an implementation or example of the present disclosure. Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” “an exemplary embodiment,” or “other embodiments,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” “an exemplary embodiment,” or “other embodiments,” or the like, are not necessarily all referring to the same embodiments.

If this specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.

As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word “about” or “approximately,” even if the term does not expressly appear. The phrase “about” or “approximately” may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/−0.1% of the stated value (or range of values), +/−1% of the stated value (or range of values), +/−2% of the stated value (or range of values), +/−5% of the stated value (or range of values), +/−10% of the stated value (or range of values), etc. Any numerical range recited herein is intended to include all sub-ranges subsumed therein.

Additionally, the method of performing the present disclosure may occur in a sequence different than those described herein. Accordingly, no sequence of the method should be read as a limitation unless explicitly stated. It is recognizable that performing some of the steps of the method in a different order could achieve a similar result.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively.

To the extent that the present disclosure has utilized the term “invention” in various titles or sections of this specification, this term was included as required by the formatting requirements document of word submissions pursuant the guidelines/requirements of the United States Patent and Trademark Office and shall not, in any manner, be considered a disavowal of any subject matter.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of various embodiments of the disclosure are examples and the disclosure is not limited to the exact details shown or described.
