BACKGROUND
Field of the Disclosure
The following is directed to a license plate holder.
Description of the Related Art
Various types of rigid objects have been marketed as license plate holders, which can attach to various vehicles in various forms and couple the license to the vehicle. The most common example of license plate holders includes frames of metal that surround a license and attach to the vehicle. However, other license plate holders exist, which are typically rigid, molded, plastic objects. Such license plate holders can have intricate constructions with various undulations, which may lead to stress risers and failure of the license plate holder. Moreover, conventional license plate holders are not typically engineered to survive exposure to a multitude of environments, and thus may be easily susceptible to chemical attack.
The industry continues to demand improvements to license plate holders.

DETAILED DESCRIPTION
The following is generally directed to a license plate holder, which may be utilized in various manners and on various objects, including but not limited to, land-based vehicles, water-based vehicles, air-based vehicles, aerospace vehicles, and a combination thereof. Moreover, the license plate holder may be configured for use in various environments, including corrosive environments, such as acidic or basic environments, and the like. The license plate holders of the embodiments herein may be generally flexible and configured to undergo repetitive stresses without catastrophic failure or fatigue. In the detailed description that follows, the features of the present invention will be described in the attachment of a license registration plate on to an existing trailer frame as found in for example a trailer used to haul a Jetski or other recreational boat. The invention may also be used for rugged attachment of a license plate to any other form of a trailer requiring a hanging or suspended plate from a light fixture or trailer frame component such as for example a motorcycle trailer.
According to one embodiment, a license plate holder assembly is depicted in FIG. 1 and FIG. 2 from front and rear views, respectively. The license plate holder assembly can include a flexible body 1, having a “T-shape” contour and openings extending through the flexible body. As further illustrated, the license plate holder assembly can be mounted onto a trailer 14 having a structural beam 15 and a lamp support bracket 16 that provides means for mounting trailer lamp 13 and flexible body 1. The flexible body 1 having been suspended and held on bracket 16 provides means to support and fasten the license plate 10 to the flexible body. A license plate frame 11 may be included in the license plate assembly, and may be added to cover the license plate 10 by one or more fasteners 12. The license plate holder may be further secured using conventional means, including for example, plate washers 21 and plate nuts 20. The license plate frame 11 may be fabricated by any common methods, including but not limited to, sheet metal formation, plastic injection molding, and aluminum casting.
The flexible body can be mounted to the bracket 16 utilizing existing threaded studs 17 typically included as part of the light assembly 13. The threaded studs 17 can pass through openings in the bracket 16 and flexible body 1. The flexible body 1 and light assembly 13 can be fastened using a plurality of nuts 18 mounted over the threaded studs 17. The oval washer 19 may be utilized to distribute the stress and prevent tearing of the flexible body 1, particularly, at the openings configured to engage the fasteners. A plurality of flat washers may be substituted for the oval washer 19. The oval washer 19 or flat washers may be placed between holder 1 and nut 18.

In one aspect, the flexible body 1 can include a generally planar two-dimensional shape as viewed in a plane defined by the thickness (i.e., the smallest dimension of the flexible body measured as the distance between the major surfaces) and the width (second longest dimension of the body extending along a major surface of the body in a direction perpendicular to the length of the body, wherein the length is the longest dimension of the body extending in the same plane as the major surface of the flexible body 1). Notably, in one particular embodiment, the flexible body 1 has essentially no major changes in contour across the majority, if not the entire, length and width of the flexible body 1.
Notably, the flexible body 1 can have a first major surface 2, which extends in a substantially single plane for a majority of the width (W) and length (L) of the flexible body 1. Furthermore, the flexible body 1 can have a second major surface 3, wherein the second major surface extends in a substantially single plane for a majority of the width and length of the flexible body 1. In certain instances, the flexible body 1 can have limited contours, particularly on the major surfaces of the flexible body 1.

The openings 1213 and 1216 may facilitate attachment of a license plate to the flexible body, while openings 1211 and 1212 can facilitate attachment of the flexible body 1201 to a structure (e.g., a portion of a vehicle, etc.). Notably, in such a configuration, the neck region 1270 of the flexible body 1201 between the top portion 1250 and bottom portion 1260 is likely exposed to the greatest loads and represent the most likely region of failure. The alternative design of the flexible body 1201 according to FIG. 12 may mitigate failure of the flexible body 1201 and extend the life of the article.
FIG. 10 includes a front view of a flexible body of a license plate holder according to an embodiment. As illustrated in FIG. 10, the flexible body 1001 can include a T-shape contour having a top portion 1050, a bottom portion 1060, and a neck region 1070 extending between the top portion 1050 and the bottom portion 1060. Moreover, the flexible body 1001 can have at least one exterior edge portion 1022 extending between a top portion edge 1023 and a bottom portion edge 1024 within the neck region 1070. According to one embodiment, the exterior edge portion 1022 can have an arcuate contour, and more particularly may define a concave curvature. In certain instances, the concave curvature of the exterior edge portion 1022 may be a complex concave curvature, wherein the contour is a non-monotonic concave curvature.
As further illustrated, the bottom portion 1060 can have cut-out region 1080. The cut-out region 1080 may be formed such that is centered along a bottom edge 1081 of the bottom portion 1060. Moreover, the cut-out region 1080 can have a first side edge portion 1082, a second side edge portion 1083, and a connection edge 1084 extending between and joining the first side edge portion 1082 and the second side edge portion 1083. In a particular embodiment, the first side edge portion 1082 can have substantially the same contour as the exterior edge portion 1022 within the neck region 1070. Without wishing to be tied to a particular theory, it is noted that formation of a cut-out region 1080 may reduce the weight of the flexible body 1001, reduce the load on the neck region 1070, and reduce the likelihood of mechanical failures within the flexible body 1001. The cut-out region 1080 may also facilitate improved manufacturability of the flexible body 1001.
Moreover, the flexible body 1001 of FIG. 10 can improve manufacturability. FIG. 11 includes a front view of a plurality of flexible bodies 1101, 1102, 1103, and 1104 according to an embodiment. As illustrated, in FIG. 11, the flexible bodies 1101-1104 may be manufactured by cutting the shapes from a larger piece of material, and such a design can reduce waste while maintaining performance of the flexible bodies 1101-1104.
