The present disclosure relates to license plate mounting systems. In particular, the present disclosure relates to a license plate mounting system with an adjustable mounting bracket using the tow eye socket on automotive vehicles.
In a majority of states in the U.S., it is required by law to display a license plate on the front of the vehicle as well as the rear. This creates both functional and stylistic challenges for the manufacturers and owners of automotive vehicles. Many types of license plate mounting systems exist to secure license plates to vehicles. Some systems connect the mounting structure directly to the front bumper with a threaded fastener, which often results in holes being created in the bumper. Alternative systems have been developed, including some that utilize the tow eye socket of the vehicle as a mounting location. However, such existing license plate mounting arrangements often have a limited adjustability range or limited degrees of freedom of adjustment for the license plate. Additionally, current arrangements often fail to provide a sufficiently close fit of the license plate to the front bumper of the vehicle, at least while also providing sufficient adjustability. It is desirable for the license plate and mount to be kept close to the front bumper for aesthetic reasons, but also for safety reasons, such as to reduce the likelihood of objects getting snagged by the edge of the license plate/mounting plate or caught in the space between the license plate/mounting plate and the front bumper.
The systems, methods and devices described herein have innovative aspects, no single one of which is indispensable or solely responsible for their desirable attributes. Without limiting the scope of the claims, some of the advantageous features will now be summarized.

With reference to
The shaft 104 can comprise a first end 106 comprising external threads 108. The threads 108 of the first end 106 can be configured to thread into corresponding internal threads of the tow eye socket. One of skill in the art will appreciate that other means of securing the shaft 104 to a tow eye socket can be used depending on the type of tow eye socket. The shaft 104 can further comprise a second end 110 opposite the first end 106 of the shaft 104. The first end 106 can also define a shoulder 152 that can abut against the tow eye socket of the vehicle. A length between the shoulder 152 of the first end 106 and the second end 110 preferably is selected to locate the adjustment arrangement 118 and the mounting plate 132 desirably close to the corresponding surface of the vehicle when the shoulder 152 abuts the tow eye socket. Advantageously, the provision of the shoulder 152 provides for precise positioning of the adjustment arrangement 118 and the mounting plate 132. The length can vary per vehicle, thus, the shaft 104 can be vehicle-specific. However, if desired, the shaft 104 can be length-adjustable.
The second end 110 can comprise friction or grip-enhancing features or members 112, such as a plurality of ribs or protrusions or other surface features that provide the second end 110 with a textured surface to enhance the rotational stability of the mounting plate 132 and/or the adjustment arrangement 118 relative to the shaft 104 once adjusted into a desirable relative position. In other words, the textured surface of the second end 110 preferably assists in inhibiting or preventing undesired relative rotation between the shaft 104 and the mounting plate 132/adjustment arrangement 118 in response to normal or expected forces during use, such as by engaging surface irregularities in, or by slightly deforming or biting into the surface of, the cooperating surface of the track member 116. The second end 110 of the shaft 104 can also comprise a threaded opening 114 configured to receive a fastener 128 of the adjustment arrangement 118.
With reference to
The track member 116 can further comprise a second side opposite the flat side 308. The second side of the track member 116 can comprise a projection, a projecting rib or a track 304. In some configurations, the track 304 can comprise a curved front surface 305. In the illustrated arrangement, the base portion 306 also has a curved front surface 307. In some configurations, the radius of the curved surfaces 305, 307 are equal or substantially equal. The track member 116 can further comprise a hole 312 configured to permit the fastener 128 to pass through the track member 166 to be threaded into the opening 114 of the shaft 104, as illustrated in the cross-sectional view of
With reference to
The track member 116 can define a dimension, or arc length 324, in a direction of the arc length 424 of the first groove 420 that is less than the arc length 424 of the first groove 420. With such an arrangement, the track member 116 engages only a portion of the first groove 420 and/or slot 410 in any particular position of the track member 116 relative to the swivel member 120. Accordingly, the swivel member 120 can slide relative to the track member 116 to allow for angular adjustment of the swivel member 120, and thus the mounting plate 132, about a substantially vertical axis in use. In some configurations, the track member 116 can be secured to the swivel member 120 (e.g., the track 304 is secured in the first groove 420) such that the track 304 is free to travel along the groove 420 but is unable to be removed completely from the first groove 420. Such an arrangement loosely couples the swivel member 120 to the track member 116 to facilitate angular adjustment. Once a desirable position has been obtained, the track member 116 and the swivel member 120 can be secured (e.g., by the fastener 128) in the adjusted position. In some configurations, the adjustment arrangement 118 provides for at least about 40-60 degrees of angular adjustment. Furthermore, if desired, a part-spherical surface can be provided to permit angular adjustment about two axes of rotation (e.g., yaw and pitch angle adjustment).
In some configurations, the first groove 420 of the swivel member 120 is curved such that curved surface 422 defines at least a portion of a circular path. The curve can be directed away from the shaft 104 such that a center 200 of the curved surface 422 of the first groove 420 is forward of one or more of the adjustment arrangement 118, the mounting plate 132, and the vehicle. In other words, an adjustment axis of rotation, which is a virtual axis of rotation of the swivel member 120 passing through the center 200, is located on an opposite side of the swivel member 120 from the shaft 104 (e.g., in front of the mounting plate 132). The distance of the adjustment axis from the swivel member 120 depends on the radius of the curved surface 422 of the first groove 420. For example, as the radius of the curved surface 422 increases, the center 200 and virtual adjustment axis moves further away from the swivel member 120. A larger radius of the curved surface 422 facilitates fine adjustment of the mounting plate 132 angle, but requires a greater distance of movement to achieve a given angular adjustment, which would increase a width of the swivel member 120 to provide the same range of angular adjustment. Preferably, the radius of the curved surface 422 is selected to provide a desirable balance between fine adjustment and distance of movement/width of the swivel member 120.
The swivel member 120 can further comprise a second groove 122 disposed opposite the first groove 420 (e.g., on a forward side of the swivel member 120 in an in-use orientation). The second groove 122 defines a curved surface preferably having a radius and an arc length that are equal to or approximately equal to the curved surface 422 of the first groove 420. The slot 410 can also communicate with the second groove 122 such that the slot 410 extends between the first groove 420 and the second groove 122, thereby creating a passage between the grooves 122, 410. As discussed in greater detail below, the second groove 122 can be configured to provide a path along which the fastener 128 travels as the swivel member 120 is adjusted.
With reference to
The washer 124 can comprise an opening 126 through which the fastener 128 passes in use. The washer 124 can be configured to distribute load of the fastener 128 over a greater area of the curved surface of the second groove 122 than the fastener head itself. As a result, the washer 124 can aid in providing a friction or pressure fit engagement between the swivel member 120 and the track member 116 as the fastener 128 is tightened into the shaft 104. In some configurations, the washer 124 can be secured within the second groove 122 such that the washer 124 is free to travel along the second groove 122 but is unable to be removed from the second groove 122.
As an example operation of the angular adjustment (yaw adjustment) of the assembly 100, the fastener 128 can be configured to pass through the washer 124, the swivel member 120, and the track member 116 to be threaded into the opening 114 of the shaft 104. Because of the grooves 122, 420 and the slot 410, even with the fastener 128 in place, the track member 116 can be free to pivot along the path created by the curved surfaces of the grooves 122, 420. However, as the fastener 128 is tightened into the shaft 104, the washer 124, swivel member 120, track member 116, and shaft 104 are compressed, thereby (e.g., frictionally) securing their positions in relation to one another. In other words, with the fastener 128 is a loosened state, the swivel member 120 is free to swivel relative to the track member 116 and the shaft member 104, however, with the fastener in a tightened state, the swivel member 120 is “pinched” between the fastener 128 and the track member 116, thereby fixing the swivel member's location with respect to the shaft 104.
To adjust the angle of the swivel member 120 relative to the shaft 104, the fastener 128 can be loosened until the swivel member 120 can be slid along the track member 116, thereby changing the angle of the swivel member 120 relative to the shaft 104. An advantage of this configuration is that the fastener 128 does not need to be completely removed from the shaft 104, but only loosened, to adjust the position of the swivel member 120.
With reference to
The mounting plate 132 can comprise a plurality of mounting positions 140a, 140b, and 140c (collectively 140) configured to receive fasteners 136a, 136b. The mounting plate 132 can be configured to couple with the swivel member 120 via the fasteners 136a, 136b. The mounting plate 132 can be secured by any number of suitable fasteners 136a, 136b. For example, the fasteners 136a, 136b can machine screws or self-drilling screws that are the same as or similar to those normally used for mounting a license plate to the relevant vehicle, among other possible options. Each of the fasteners 136a, 136b can include a same or varying length. The length of the fasteners can depend on the thickness of the mounting plate 132 and mounting hardware in some instances.
The mounting plate 132 may further comprise one or a plurality of slots (collectively or generically 144) through which the fastener 128 can pass and be accessed. Although in the illustrated arrangement a discrete slot 144 is provided for each set of mounting holes 140a, 140b, 140c, in other arrangements a single slot 144 or other opening can cooperate with more than one (or all) of the mounting holes 140a, 140b, 140c. With the mounting plate 132 coupled to the swivel member 120, one of the slots 144 is aligned with the second groove 122. Thus, an advantage of the present configuration is the ability of the fastener 128 to be accessed without having to remove the mounting plate 132 from the swivel member 120. Further, the slots 144 of the mounting plate 132 enable adjustment of the mounting plate's position (e.g., yaw) without having to disassemble any portion of the assembly 100.
Moreover, the fastener 128 can be conveniently accessed from the front of the mounting plate 132 by passing a tool (e.g., a screwdriver) through a relevant one of the slots 144. In some configurations, the fastener 128 may extend partially or fully through the slot 144 such that the tool does not pass through the slot 144 during the adjustment process. Certain prior art designs require adjustment access from behind the mounting plate—such as from the top, bottom or sides. Such an arrangement often requires a tool access gap to be provided between the rear side of the mounting plate and the corresponding surface of the vehicle, which spaces the mounting plate further from the vehicle than desired and can create a snagging hazard. By permitting tool access from the front, the illustrated arrangement of the assembly 100 advantageously allows a closer fit to the body of the vehicle. In some configurations, the plurality of mounting positions 140 can be arranged such that the “height” of the mounting plate 132 in relation to the swivel member 120 and/or shaft 104 can be adjusted.
With reference to
The adjustability of the assembly 100 will now be described. Based on the above described configurations, the yaw angle of the mounting plate 132 can be adjusted by loosening the fastener 128 and rotating the mounting plate 132 such that the swivel member 120 slides, via the slot 410, along the track 304 of the track member 116. Yaw angle adjustment of the mounting plate 132 allows the license plate to be aligned with a vehicle's front bumper. In some configurations, the roll angle, or angle about the axis of the shaft 104, of the mounting plate 132 can be adjusted by loosening the fastener 128 and rotating the track member 116 in relation to the shaft 104. In some configurations, the vertical position of the mounting plate 132 in relation to the shaft 104 can be adjusted using a desired one of the plurality of mounting positions 140a, 140b, 140c and slots 144 to mount the mounting plate 132 in different positions relative to the swivel member 120. Further, as is shown in
Additional Considerations
The materials of the components described herein can be selected to comply with standards and requirements of various jurisdictions. The materials can advantageously be weather-proof or be selected to withstand various weather conditions. The materials can be selected to be durable, flexible, rigid, and/or decrease the overall cost of the system.
It should be emphasized that many variations and modifications may be made to the herein-described embodiments, the elements of which are to be understood as being among other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims. Moreover, any of the steps described herein can be performed simultaneously or in an order different from the steps as ordered herein. Moreover, as should be apparent, the features and attributes of the specific embodiments disclosed herein may be combined in different ways to form additional embodiments, all of which fall within the scope of the present disclosure.
Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or states. Thus, such conditional language is not generally intended to imply that features, elements and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or states are included or are to be performed in any particular embodiment.
Moreover, the following terminology may have been used herein. The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The term “ones” refers to one, two, or more, and generally applies to the selection of some or all of a quantity. The term “plurality” refers to two or more of an item. The term “about” or “approximately” means that quantities, dimensions, sizes, formulations, parameters, shapes and other characteristics need not be exact, but may be approximated and/or larger or smaller, as desired, reflecting acceptable tolerances, conversion factors, rounding off, measurement error and the like and other factors known to those of skill in the art. The term “substantially” means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.
Numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also interpreted to include all of the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but should also be interpreted to also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3 and 4 and sub-ranges such as “about 1 to about 3,” “about 2 to about 4” and “about 3 to about 5,” “1 to 3,” “2 to 4,” “3 to 5,” etc. This same principle applies to ranges reciting only one numerical value (e.g., “greater than about 1”) and should apply regardless of the breadth of the range or the characteristics being described. A plurality of items may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. Furthermore, where the terms “and” and “or” are used in conjunction with a list of items, they are to be interpreted broadly, in that any one or more of the listed items may be used alone or in combination with other listed items. The term “alternatively” refers to selection of one of two or more alternatives, and is not intended to limit the selection to only those listed alternatives or to only one of the listed alternatives at a time, unless the context clearly indicates otherwise.
