The present invention relates to a firefighting apparatus, such as a fire truck, a trailer or other vehicles, and more particularly to a firefighting apparatus with a light integrated grab handle.
Fire trucks and rescue vehicles typically include multiple signal and/or warning lights. These lights are available in a variety of styles and designs unique to the location of the lights on the truck and the purpose of the lights. Depending on local jurisdictional rules, fire trucks often have signal and/or warning lights on many different locations of the truck, inside and out. Popular types of lights used on fire trucks include separate strobe lights, surface mount lights, light bars, traffic advisor lights and grille lights. The lights are available in many different warning light colors, the most popular colors being red and white, and in some jurisdictions, blue and yellow. Many higher end lights come preprogrammed to emit a multitude of flash patterns.
An issue with almost all conventional fire truck lights is that they require holes be drilled, punched or formed through panels of the body, cab and/or frame of the truck. The lights are then mounted in the holes, or the lights include wiring that extends through the holes. These light holes are in addition to the multiple other holes typically found on a fire truck to accommodate other accessories such as latches, steps and the like. The more holes there are in the truck, the more likely it is that water, chemicals and other debris can inadvertently enter the truck over time, particularly if seals around the holes degrade. In turn, this leakage, particularly in climates where salt is used on roads during winter, can lead to rust, which can prematurely compromise a fire truck's components.
Signal, warning and other lights on fire trucks and rescue vehicles are helpful and even required in many applications. The additional holes that are used to mount the lights, however, are undesirable. Accordingly, there remains room for improvement in the mounting of lights to fire trucks while reducing the overall number of holes in them, and the overall number of separate accessories mounted on the trucks.
A firefighting or rescue apparatus including a light integrated grab handle mounted to the frame, wherein the grab handle is operable to provide signal, brake, and/or warning illumination at the location of the handle. The grab handle provides dual functionality as a structural handle adapted to provide personnel with a grasping surface to enter or dismount the apparatus, as well as lights to provide illuminated warning, brake, traffic and/or signal lights to observers of the firefighting apparatus when actuated.
In one embodiment, the signal light grab handle is mounted to an exterior outer panel of a cab, body or frame of the apparatus. The signal light grab handle can include one or more lights joined with one or more connector wires to provide power to the lights and thereby eliminate them. The connector wires can be hidden within the structure of the signal light grab handle and can pass through internal bores thereof, and ultimately through a concealed and protected hole defined by the exterior outer panel, into the interior of the apparatus.
In another embodiment, the signal light grab handle is in electrical communication with a controller and a power source. The controller can selectively provide power from the power source to the lights. The controller can control the signal light grab handle so that is operable in a flashing mode, in which the signal light grab handle emits illumination in a predefined flashing pattern, as well as a sleep mode, in which the signal light grab handle emits no illumination. The controller also can control the signal light grab handle so that it emits light in a constant mode without interruption in illumination for a period of time.
In still another embodiment, the signal light grab handle can be constructed to include a central grab rail within which one or more recesses can be defined. These recesses can be configured to receive and protect the lights of the signal light grab handle. Optionally the lights can be disposed in a housing constructed from a weather resistant and UV resistant material, such as a polymer. This housing can further be translucent and/or transparent so that illumination emitted by the lights passes through it is visible through the housing.
In yet another embodiment, the light of the signal light grab handle can be in the form of a strip having multiple light emitting diodes (LEDs), electrically connected in series and/or in parallel. The LED strip can be positioned so that it is angled outwardly, away from the body of the truck. The LED strip can include a primary axis of illumination, which optionally can be generally perpendicular to the plane in which the LEDs of the LED strip are disposed. The primary axis of illumination can point outward, away from an outer panel of the body, for example, a cab of a fire truck.
In even another embodiment, the firefighting apparatus can be in the form of a fire truck, including a frame with a cab mounted over one or more wheels of the truck. The cab can include one or more doors on one or both sides of the cab. The signal light grab handle can be mounted so that the grab rail is immediately adjacent at least one of the doors to provide a graspable portion of the truck so that an occupant can ingress and/or egress relative to a cab interior.
In a further embodiment, the cab can include a first door and a third door on a single side of the truck. The signal light grab handle can be mounted rearward and distal from the first door, and forward of the third door, so that the signal light grab handle is between the first door and the third door, and not mounted on either of the first door or the third door.
In even a further embodiment, the signal light grab handle includes a longitudinal axis extending from an upper end to an opposing lower end. The longitudinal axis can be oriented substantially vertically on the truck. The signal light grab handle also can be rigidly and immovably joined with the truck. An open space can be located between the central grab rail and the exterior outer panel of the truck. This open space can be sized to enable human digits to project between the central grab rail and the outer panel while an occupant grasps the central grab rail with a hand.
In still another embodiment, the firefighting apparatus can be in the form of a fire truck, including a frame with a cab mounted over one or more wheels of the truck. The cab can include a rear end, disposed rearward of rear axles of the truck. The rear end can include a rear bumper and a hose bed opening. The light integrated handle can be mounted so that the grab rail is immediately adjacent and optionally below the hose bed opening, and at least two feet above the rear bumper to provide a graspable portion of the truck so that an occupant can ingress and/or egress relative to a platform on the rear end.
In a further embodiment, the light integrated grab handle includes a longitudinal axis extending from a left end to a right end, or from one side of the truck to the other. The longitudinal axis can be oriented substantially horizontally on the truck, parallel to the bottom of the hose bed opening and to a platform/bumper located at the bottom of the frame. The light integrated grab handle also can be rigidly and immovably joined with the truck. An open space can be located between the grab rail and an exterior outer panel of the truck. This open space can be sized to enable human digits to project between the grab rail and the outer panel while an occupant grasps the grab rail with a hand.
The current embodiments provide a simple and effective construction that can enable features of a firefighting or rescue apparatus, such as a fire truck, to serve multiple functions. Where a firefighting apparatus is dispatched to an emergency location, the light grab handle can be selectively illuminated, optionally in a flashing pattern driven by the controller, to emit illumination and provide warning lights to observers of the fire truck, thereby alerting the observers to the emergency or other situation at that location. The light grab handle also can be selectively illuminated to operate as a signal light, for example, to act as a turn signal indicating to observers of truck that the truck is about to turn in a particular direction. The signal light grab handle of course also can function as a grasping surface to assist occupants who desire to board or deboard the apparatus. The signal light grab handle can reduce the overall number of different lights and handles attached to an extending from the exterior of the truck, and thus the number of holes in the exterior of the truck. This can simplify mounting of these elements and can enhance the integrity of the fire truck over time.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiments and the drawings.

A current embodiment of a firefighting apparatus is illustrated in
The fire truck 10 can include a frame, also referred to as a body herein, which can be mounted to a chassis which can be further mounted to multiple wheels 32. The wheels can be attached to conventional front 32AF and rear 32AR axles, which are further attached to the chassis of the truck. The fire truck can be mobilized via an internal combustion engine which drives the wheels via a transmission.
The fire truck 10 can include one or more internal electronic or computers or controllers that can operate the engine, transmission, or steering control mechanism to enable the front wheels to be steered upon transport to an emergency location. As used herein, an emergency location can be a scene of a traffic accident, a boating accident, a plane accident, a man-made or natural disaster, and/or a terrorist attack, or any other location where one or more victims' lives are endangered or otherwise compromised.
The frame or body 30 can include a forward portion 31 and a rearward portion 33 located at opposite ends of the fire truck 10. Generally the rear wheels 32R and their axle 32AR are located in the rearward portion 33 of the fire truck 10. The front or steering wheels 32 can be located in the forward portion 31 of the fire truck, and mounted to a front axle 32AF. The frame 30 in the forward portion 31 can include a cab 34. The cab 34 can house occupants, such as firefighters or rescue personnel, as they are transported to and from an emergency location. The cab 34 can include controls, such as a steering mechanism and various displays inside the cab to monitor and evaluate the operation of the vehicle 10. The cab can terminate a distance of several feet rearward of the front wheels 32, or generally forward of the pump controls 36 and/or rearward portion 33 of the fire truck 10.
A pump control panel 36 can be mounted rearward of the cab 34. Under or behind the pump control panel 36, one or more pumps 37 can be mounted. These pumps can be mounted to the frame. Generally, the pump 37 can be in fluid communication with a firefighting fluid tank 38 mounted to the frame in the rearward portion 33, and/or a source of firefighting fluid external to the truck, such as a fire hydrant. The pump also can be in fluid communication with one or more hoses or waterways 47 as described below. The pump can be configured to convey firefighting fluid from the external source or the tank to the hose 47 in a forced manner so that the firefighting fluid can be applied to a fire.
The hose 47 can be operable to transfer a continuous supply of firefighting fluid to the water outlet 48 which is generally in the form of a nozzle. Generally the hose receives pressurized firefighting fluid from a pump 37 and storage tank 38 on the frame 30. A nozzle 48 assists in pressurizing and/or shaping the continuous stream of firefighting fluid from the hose 47 toward a fire in a burning structure, such as a building, vehicle or other item.
In addition to the cab 34, the frame 30 optionally can include a body 39, rearward of the cab, having lockers 38 mounted rearward of the pump control panel 36, generally in the rearward portion 33 of the fire truck 10. The body can conceal all or a portion of the tank 38. The lockers optionally can be located on and accessible from the first 35A and second 35B sides of the fire truck, and can be sized and configured to store supplies and equipment useful for easy access at an emergency location.
Turning now to
The first door 41 can be mounted in an opening 41O defined by the cab, and can be selectively opened and closed relative to the cab, to provide an occupant ingress and egress relative to a cab interior 34I. The first exterior door 41 can be located forward of the front axle 32AF and can provide access to a driver's seat of the vehicle, optionally including a steering wheel (not shown) near the seat.
The first door 41 can be swingably mounted to the cab via a hinge 41H so that the door can swing open in the direction S1, generally toward the front of the truck and away from the front wheels 32 and cab 34, as well as the signal light grab handle 71, described further below. The door 41 can include a front edge 41F and a rear edge 41R. The door also can be outfitted with a handle 41A that is configured to open and close the door, providing a securing latch or lock mechanism so that the door remains shut when desired.
Rearward of the first door 41 an outer exterior panel 50 can be disposed. This outer panel can form another portion of the cab 34, and can be located above the front wheel 32. This exterior panel can be in the form of a sheet of metal, optionally painted, coated or treated on the exterior surface thereof. The panel can be mounted to an underlying structure, such as an elongated tube or support frame via welds, fasteners, rivets and the like. This exterior panel 50 can be mounted rearward of the rear edge 41R of the first door 41. The exterior panel can extend from above the wheel well 32W, or above the first axle 32AF toward a roof 34R of the cab.
Optionally, the cab 34 can include a second door 43 on the passenger side or second side 35B of the truck 10. This door can be set up the same way as the first door 41. The cab 34 also can include a third door 43 mounted rearward of the first door 41 as well as rearward of the exterior outer panel 50 on the first side 35A of the truck 10. This third door can be mounted with a hinge 43H to the cab 34 and optionally to the exterior panel 50. This door can include a front edge 41F and a rear edge 43R. This third door also can include a separate dedicated handle or latch 43A to enable an occupant to open and close the third door. Generally this third door 43 can be mounted rearward of the front axle 32AF and can provide ingress and egress relative to the cab interior 34I. This third door also can swing open forwardly, toward the first signal light grab handle 71 but away from the second signal light grab handle 73 as described below. Rearward of the third door 43, an additional or second outer panel 52 can be mounted to complete the portion of the cab behind that third door.
Optionally, the exterior or outer portions of the cab 34, the first exterior door 41, the third exterior door 43 and the panels 50 and 52 form portions of the cab exterior, along with any windows associated with the cab.
Further optionally the fire truck 10 can be outfitted with a light bar 61 mounted to the roof 34R of the cab 34. The truck also can include headlights 62 mounted to the front of the cab to provide illumination while the fire truck is driving in dark environments. The truck optionally can include signal or warning lights 63 mounted on the bumper 34B of the cab. As used herein, signal lights, warning lights, traffic advisor lights, brake lights and signal warning lights can be used interchangeably, and in general can encompass lights that provide signals, indications and/or warnings. Additional lights 64 and another signal light grab handle, also referred to as a light integrated handle 171, as described in connection with the alternative embodiment below, can be included on the truck in the rearward portion 33. All of these lights can be in communication with a network and/or controller 10C mounted on board the truck 10. This controller can be a computer or similar device adapted to control one or more of the lights of the truck as well as other operating systems of the truck. This controller optionally can be in communication with a human interface, such as a toggle switch, control knob or the like so that an occupant can select different modes of operation for the lights.
The controller 10C optionally can be configured to operate any lights on the truck in one or more modes. For example, the controller can operate the lights in a sleep mode, so that one or more of the lights emit no illumination. Generally in this mode, no power or a very low power is supplied to the respective lights on board the truck, for example, to a turn signal, a warning light, headlights and the lights of the signal light grab handles 71 and 73 as described below. As another example, in a signal mode, the controller can provide power, upon an input selection by an occupant, to preselected lights, for example to a turn signal, a warning light, headlights and/or signal light grab handles to illuminate the respective lights constantly and/or intermittently depending on the application and the particular light. As yet another example, in a flashing mode, the controller can provide power, upon input selection by occupant, to preselected lights, for example to the light bar 61, the warning lights 63 and 64, as well as the lights of the signal light grab handles 71 and 73 as described below. In this flashing mode, lights controlled by the controller can emit illumination in a predefined flashing pattern. For example the controller can illuminate the light bar 61 so that it flashes and/or illuminates for predetermined amounts of time in predetermined patterns. As another example, the controller can illuminate one or both of the signal light grab handles 71 and 73, for predetermined amounts of time in predetermined patterns. In such a flashing pattern, each of the signal light grab handles 71 and 73 on a side of the truck can be illuminated sequentially, simultaneously, or in some other timed pattern to provide warning or signal function. Of course, in some applications the controller can illuminate the signal light grab handles 71 and 73 in the signal mode, in which case those handles can operate as turn signals or other illumination.
As mentioned above, the truck 10 includes one or more signal light grab handles 71, 72, 73 and 74. As shown in
Details of the signal light grab handles will now be described with reference to the first signal light grab handle 71 in
The first signal light grab handle 71 can be mounted rearward and distal from the first door 41. As an example, the signal light grab handle 71 can be mounted rearward of the rearward edge 41R of that door 41. The signal light grab handle 71 can be mounted above the wheel well 32W, as well as above the front axle 32AF and wheel 32. The signal light grab handle 71 can be mounted below and distal from the roof 34R. Of course in some applications, the handle can be mounted to the roof, or even to the body, rearward of the cab.
The signal light grab handle 71 can be mounted rearward of the handle or latch 41A the first door 41. The handle also can be mounted forward of the optional third door 43, in particular, forward of the hinge 43H of the rearward door. Where the cab 34 includes first and third doors on the first side 35A, the first handle 71 can be mounted between the first and third doors, but closer to the first door, so that handle 71 can be used by an occupant to enter the opening 41O that the first door closes.
The signal light grab handle 71 can be rigidly and immovably joined with the truck, in particular the cab 34 and specifically to the exterior of the cab 34. Generally, this signal light grab handle is mounted outside the interior 34I of the cab. Further optionally, the signal light grab handles include no parts or portions that move in any direction relative to the cab or exterior unless those parts and/or the signal light grab handle is disassembled relative to the truck. Even further optionally, there are no moving or swinging components to the signal light grab handle.
As illustrated in
As shown in
The central grab rail 71G optionally can define an internal bore 71B that extends from the upper to the lower end. Although it is shown as triangular in
The central grab rail 71G, as shown in
The signal light grab handle 71 can include a light strip 90 as mentioned above. This light strip can be in the form of a strip having multiple light sources. For example, the strip can be an LED strip, having multiple light emitting diodes or LEDs 91 mounted to a base strip 92. The multiple LEDs can be in series and/or parallel to one another or otherwise electrically coupled to one another and optionally to a connector wire 99. The LED strip 90 optionally can include a printed circuit board, converter, inverter or other device 93 to assist in the operation of the LEDs.
The LED strip can extend from the upper end 71U to the lower end 71L, the central grab rail 71G and can be housed substantially within the recess 71C. In some cases, the LED strip 90 and/or the housing can be mounted below the outermost peripheries 71P of the central grab rail so that it is less likely to be damaged via impact with objects or crushing forces while grasping the rail. This LED strip 90 can be disposed directly in the recess 71C of the central grab rail 71G, or it can be housed in a housing 80.
Optionally, the multiple LEDs 91 are aligned linearly with one another along the LED strip 90. The respective LEDs, for example at least 5, 10, 15 or more LEDs, can be spaced optionally 1 mm to 100 mm, further optionally 1 mm to 50 mm, and even further optionally 1 mm to 25 mm from one another. The LEDs also can be aligned to present a primary axis of illumination PAL, along which a majority of light is emitted from the strip. The amount of illumination can be varied depending on the transmissive and/or reflective properties of the housing 80 and/or the configuration of the LEDs. Indeed, the housing can be formed to include certain reflective surfaces and/or prisms to focus the primary axis of illumination in a particular direction. Generally, the primary axis of illumination PAL faces outward relative to the outer panel 50 and/or the cab 34 of the truck 10. This is so that the emitted illumination is not wasted by the LED strip being pointed toward the truck. Optionally, as shown in
As mentioned above, the housing 80 can be constructed to house the LED strip 90. This can protect the LED strip from liquids, heat, moisture or other environmental factors to preserve or prolong the life of the LEDs. Optionally the housing can include a base 82 and multiple exterior surfaces 85A, 85B and 85C. These exterior surfaces can angle relative to one another as shown, or the surfaces can be part of a compound curved surface. The base 82 can be sized to fit within the recess 71C, and in particular to fit at least partially between the shoulders 71H1 and 71H2. The housing can include one or more flanges 81 and 83 extending from the base and/or adjacent the base. These flanges 81 and 83 can be slightly tapered on a front side so that when the housing is pressed between the shoulders of the recess, those flanges can effectively slide past the shoulders. After they slide past the shoulders, a rearward lip of the respective flanges can engage the shoulders effectively trap the housing within the rail 71G.
Optionally, in some applications, the flanges 81 and 83 are not tapered. In this case, they can be slid from an end, for example the upper end or lower end of the rail into the recess, for example, into a slot 71SS so that the shoulders capture the housing and/or board. Further optionally, after installation of the housing 80 in the recess 71C, that housing can be glued, cemented, or fastened with fasteners to the grab rail for a secure fit.
The housing 80 can be constructed from a translucent, transparent and/or light transmitting material, for example clear or frosted polymers, composites and the like. Of course, in some applications, the housing can be constructed from an opaque material having reflectors therein and minute openings within which the LEDs or other light sources project.
As shown in
Optionally, in some applications, the connector wire 99 can be absent. In this case, the LED strip 90 can include circuitry so that it can be inductively coupled to an onboard power source and/or controller 10C within the cab. Of course, other modes of powering the lights are contemplated, without use of the connector wire 99.
The signal light grab handle 71 can be mounted fixedly and immovably to the truck. As shown in
The upper bracket 77UB can include a pillar 77P that extends to a base 77B. The pillar can include a pillar bore 77M that extends from the internal bore 77I and through the base 77B of the bracket 77UB. This pillar bore 77M can align with a hole 51HU defined by the outer panel 50. Accordingly, the connector wire 99 can be extended through the internal bore, the pillar bore and the base, ultimately into the interior of the cab and behind the exterior or outer panel 50. The base 77B can include one or more base holes that are aligned with corresponding holes in the outer panel 50. One or more fasteners F can project through the base holes and can be screwed into the outer panel 50 to secure the bracket to that outer panel. Of course, in other constructions, the fasters can be deleted and the base welded to the outer panel 50. In yet other constructions, the pillar 77P can be threaded into corresponding threads defined by the outer panel 50. Other constructions are contemplated to secure the bracket to the panel.
The lower bracket 77LB can be similarly constructed to the upper bracket 77UB, and can include similar features. Optionally, if additional connector wires are used with the LED strip 90, those wires can be snaked through bores of the lower bracket 77LB and through a lower hole 51HL defined by the outer panel 50.
Although not shown, one or more elastomeric gaskets optionally can be disposed between the base 77B in the exterior panel 50 to prevent liquids, contaminants and/or debris from entering the cab through the holes for the fasteners and the connector wire. Further, the brackets can include one or more seals to further prevent fluids from entering the cab through those brackets.
As mentioned above, the fire truck 10 can include more than one signal light grab handle, for example, as illustrated in
Operation of the firefighting or rescue apparatus of the current embodiments will now be described. The firefighting apparatus 10, optionally in the form of a pumper fire truck, can be used to fight fires in a building or other structure. As illustrated in
As shown in
After the fire truck 10 is no longer in transit, or is removed from the emergency location, the lights, including the signal light grab handles can be put into a sleep mode so that they no longer emit illumination. The firefighting apparatus then can be transported back to its garage or station.
A first alternative embodiment of the signal grab handle is shown in
The rear end 133RE can include an opening 140O. This opening 140O can be associated with a hose bed 140 that extends from the rear end toward the rear axles 32AR, and optionally forward of the rear axle 32AR. This hose bed can form a portion of the rearward portion 133 of the truck 110. This hose bed 140 can include a floor 140F and first and second sides 140S1, 140S2 collectively form the hose bed. The hose bed can be structured so that a folded up hose for use in firefighting can be disposed on the floor and secured within the hose bed 140. The hose bed can include a forward wall (not shown) opposite the opening 140O. The opening 140O can be outfitted with a cover 140C. The cover can be any type of material, such as a fabric sheet, a woven tarp and/or a polymeric or metal plate, depending on the application. The cover again generally closes the hose bed 140O opening yet provides easy access to the hose stored in the hose bed. Optionally, the cover 140C can include one or more straps 140S. The straps can be elastic and/or inelastic webs, ropes, strands, cords, filaments or the like can be configured to wrap at least partially around the elongated light integrated handle 171. In some cases, fasteners, such as hooks, can be secured to the ends of the straps for the securement. With this securement, the cover 140C is less likely to flap in the wind as the apparatus 110 travels on a roadway or at speed.
The rear end 133RE can include a rear bumper 180 that forms the rearward most portion of the rear end. The bumper can be constructed from a solid and/or rigid material, such as stainless steel and/or aluminum. The bumper also can include impact absorbers (not shown) therein. The rear lower bumper 180 is generally disposed adjacent a bottom most portion of the body 130B in the rear end 133RE, Adjacent and/or slightly above the bumper 180, a second platform 180P2 can be disposed. This platform 180P2 can include gripping structures, and optionally can be in the form of diamond plate. The gripping structures can assist in obtaining a solid foothold when standing on the platform 180P2. This platform can be referred to as the lower platform. It can be disposed below the hose bed 140, the hose bed flooring 140F, and further below the elongated light integrated handle 171 as described below. Depending on the application, the elongated light integrated handle 171 can be optionally 2 to 8 feet above the platform, further optionally 3 to 6 feet above the platform and even further optionally 4 to 6 feet above the platform. The platform also can be substantially horizontal and/or parallel to the other components of the rear end of the truck, such as the floor 140F. Optionally, a storage bin 182 can be disposed immediately above the platform. The storage bin can be used to store tools, equipment and the like and can include a door that swings or folds open.
The rear end 133RE can include a first platform 180P1 that is disposed above the second platform 180P2. This first platform can provide yet another step up so that a user can easily access the hose bed 140. The first platform can be approximately 1 foot to about 2 feet above the second platform or other distances depending on the particular application and structure of the rear end. Optionally, both platforms, the floor, the rear lower bumper and the light integrated handle can be generally horizontal when the truck is parked on a horizontal surface. By being generally horizontal, it is meant that these elements do not deviate from the horizontal plane by more than about 1° to about 5°. Further optionally, the platforms can be of different widths. For example, the second platform can be wider than the first platform or vice versa.
In some constructions, both platforms and additional steps 181S can be located within a recess 180R that is formed in the rear end 133RE and in particular the rear portion 133 of the truck 110. This recess can be optionally 6 inches to 24 inches, further optionally 12 inches to 18 inches, deep as indicated by the depth D5. Of course, other depths may be selected depending on the application.
The recess 180R can be bounded by sidewalls 180SW as well as a rear exterior outer panel 185. This rear exterior outer panel 185 can be disposed above the first and second platforms, as well as below the floor 140F of the hose bed 140. The rear exterior outer panel 85 can be substantially perpendicular to the floor 140F as well as the one or more platforms included with the rear end. As described further below, this panel can be configured so that the light integrated handle can be joined with it and/or to an underlying substructure or frame, which is also considered to be part of that panel. The recess, and generally the panel, can be about 72 inches wide. The panel can be wider or narrower depending on the particular application and the configuration of the rear end 133RE. As will be appreciated with further discussion below, the light integrated handle 171 can be disposed substantially within the recess 180R, below the floor 140F of the hose bed 140.
As can be seen in
As shown in
As mentioned above, the light integrated handle 171 can be substantially similar in structure and/or function and/or operation to the signal grab handle 71 of the embodiment described immediately above. There can be several differences however. For example, the elongated light integrated handle can span from a left side L of the body to the right side R of the body and rear end. Optionally, the light integrated handle 171 can be disposed below the hose bed, and more particularly, below the floor 140F of the hose bed. The light integrated handle 171 also can be disposed above the rear bumper 180, as well as the first and second platforms and generally joined to the rearward outer exterior panel 185. The light integrated handle can be substantially parallel to various components of the rear end, for example, the lower rear bumper, the floor, the first platform, the second platform, steps disposed in the rear end, and/or other components of the rearward portion 133 of the truck 110.
The elongated light integrated handle 171 can be mounted with one or more brackets. As shown in
The grab rail 171G can be an elongated structure with a gripping surface on the exterior thereof, similar to the embodiment of the central grab rail described above. The grab rail also can be constructed to include an elongated recess spanning between a first or left end 171L and the second or right and 171R. These ends can be disposed equidistant from the body longitudinal axis BLA on the respective left and right sides thereof. The grab rail also can define an elongated recess 171CS configured to receive a portion of the light strip 190 and any associated housing 180H. The light strip, light elements and housing 180H can be similar to the same components described in the current embodiment above. For example, the light strip 190 can be at least partially disposed within the elongated recess 171CS, with a light strip disposed outwardly relative to the rear exterior outer panel. The light strip 90 also can be joined via a wire 199 that extends through at least one of the brackets and a corresponding hole 185H defined by the rear outer exterior panel 185, similar to the same components in the signal grab handle described above. Again, due to the similarity, these components they will not be described again in detail here.
The elongated light integrated handle 171 can include a plurality of individual light sources thereon, and in particular, associated with the light strip 190. These light sources can be LEDs, incandescent bulbs, or any other type of lighting element. These lights, and the light integrated handle can provide at least one of warning lights, which can include traffic advisor lights directing traffic in a particular direction as well as general flashing lights that flash randomly to draw attention to the bank of lights, turn signal lights, which can indicate left and/or right turn signals, and/or brake lights, which can indicate braking of the vehicle. The lights and the light strip can be controlled by the controller 10C as with the embodiment described above. For example, the controller can control the light strip so that it operates in an illumination mode in which one or more of the lights emit illumination in a predefined manner and/or a sleep mode in which the plurality of lights emit no illumination.
In some cases, the elongated light integrated handle 171 can include specific banks or sets of lights, which can be selectively illuminated depending on the particular instruction from the controller 10C or actions taken by a driver of the truck 110. For example, the elongated light integrated handle can include a left side 171L and a right side 171R. A first bank of lights 191 can be disposed and/or adjacent the left side 171L. A second bank of lights 192 can be disposed adjacent the right side 171R. The bank of lights 191, in particular the individual light sources thereof, can be configured to synchronously illuminate with the left turn signal 191T. This turn signal 191T can be located farther from the longitudinal axis BLA than the bank of lights 191. This bank of lights also can be disposed at a different height or level relative to the bumper and/or platform when compared to the turn signal 191T. Likewise, the bank of lights 192, and in particular, the individual light sources thereof, can be configured to synchronously illuminate with the right turn signal 190T. This turn signal 190T can be located farther from the longitudinal axis than the bank of lights 192.
Optionally, the controller 10C can be configured to control the turn signals and respective outer banks of lights in the integrated light handle to illuminate them simultaneously to indicate a turning direction. For example, as shown in
The integrated handle light 171 also can be configured to include a third bank of lights 193. This bank of lights can generally be disposed adjacent the central bracket 177CB when included. The center bracket can be outfitted with an opening 177O to enable the light bank 193 to be viewed adequately. This light bank 193 can be configured to synchronously illuminate with the brake lights 190B of the truck 190 when those brakes are actuated. For example, referring to
The integrated handle light optionally can be configured to provide warning lights. As an example, all the banks of lights in the light strip can illuminate and/or flash in a preselected and/or random manner to catch the attention of individuals near the truck. Optionally, these warning lights can include an illumination that acts as a traffic advisor, directing traffic to the left or to the right of the truck 110. For example, as shown in
