Description

BACKGROUND

Trailers and other towed vehicles are often bulky and obstruct rearward views of drivers in towing vehicles. Additionally, trailers and other towed vehicles often carry large items that also obstruct rearward views. This makes it difficult to navigate traffic and to drive in reverse with a trailer attached.

To provide unobstructed rearward views, current solutions include installing cameras on rear ends of the trailers for capturing images of the rearward views and sending the images to displays in the cabins of the towing vehicles. However, installation of such cameras is difficult. In order to install a camera, holes are drilled in a surface of a trailer, power wires of the camera are fed to a power source, and an image feed wire must be run through the trailer and towing vehicle and into the cabin of the towing vehicle. Such installment is labor intensive and requires expertise.

Current solutions for avoiding feeding wires through trailers and towing vehicles involve installation of wireless cameras that are battery operated and send signals to wireless displays in the cabins of the vehicles. However, installing such cameras requires drilling holes in the walls of the trailers or using adhesives. Drilling holes risks damage to the trailers and adhesives do not always keep the cameras attached. Additionally, batteries of the cameras often die prematurely, so the cameras are unreliable without routine battery checks and maintenance.

The background discussion is intended to provide information related to the present invention which is not necessarily prior art.

SUMMARY

The present invention solves the above-described problems and other problems by providing a distinct advance in the art of camera mounts. More particularly, embodiments of the present invention provide systems and methods for attaching a camera to a trailer without damaging the trailer and without having to feed wire through the trailer.

A mount according to an embodiment of the present invention is provided for attaching a camera to a support surface of a trailer or other towed vehicle. The support surface is configured for supporting a light housing and has a hole for receiving a fastener for securing the light housing to the support surface. The mount broadly comprises a flange and a bracket extending below the flange. The flange comprises a light housing hole for receiving the light housing therethrough, and a fastener hole for receiving the fastener. The bracket is configured to engage the camera.

The light housing hole of the flange enables the light housing to be passed therethrough without disconnecting any wiring connected to the light housing. The hole of the light housing can then be aligned with the fastener hole of the flange to receive the fastener. The fastener can then be used to secure the light housing and mount to the support surface with the mount sandwiched between the light housing and the support surface. This prevents damage to the trailer when installing the camera and allows the camera to be wired to any wiring of the light housing and attached via the bracket.

A camera device according to another embodiment of the invention is provided for attaching to a support surface of a trailer or other towed vehicle. The support surface is configured for supporting a light housing and has a hole for receiving a fastener for securing the light housing to the support surface. The camera device comprises a flange, a bottom portion, a bracket, and a camera. The flange comprises a light housing hole for receiving the light housing therethrough, and a fastener hole for receiving the fastener. The bottom portion extends downwardly from the flange. The bracket is attached to the bottom portion, and the camera is attached to the bracket.

Another embodiment of the present invention is a method for securing a mount to a support surface of a trailer or other towed vehicle. The method comprises unsecuring a light housing from the support surface; threading the light housing and a length of light wires extending from the light housing through a light housing hole of a mount; positioning the mount against the support surface; aligning the light housing with the mount so that a hole of the light housing is coaxial with a fastener hole of the mount; and fastening a fastener through the hole of the light housing and the fastener hole to secure the light housing and mount to the support surface.

An exemplary way of installing the camera device 10 is described herein. The camera device 10 may be installed by removing the face plate 20 of the light 16 to gain access to the fasteners 26, 28 securing the light housing 18 to the support surface 12, as depicted in FIG. 3. The fasteners 26, 28 are unfastened to unsecure the light housing 18 from the support surface 12. The wires 30, 32 connected to the light housing 18 may be spliced to connect to camera wires 86, 88 (as shown in FIG. 11). The camera wires 86, 88 may already be connected to the camera 40 and extend through the wire hole 68 of the bottom portion 36.

The mount 39 may be installed on the support surface 12 by pulling the light housing 18 through the light housing hole 56 (with the wires 30, 32 still connected), as depicted in FIG. 10. The flange 34 may then be placed on the support surface 12 with the exterior walls 50 abutting the support surface 12, as depicted in FIG. 12, thereby maintaining the cavity 62 between the face place 44 and the support surface 12. The wires 86, 88 connected to the camera 40 may be positioned in the notches 64, 66 (shown in FIG. 5) and extend into the cavity 62 to connect to the light wires 30, 32. The flange 34 may be positioned so that the two or more fastener holes 58, 60 of the face plate 44 are aligned with pre-existing holes 27, 29 in the support surface 12. Turning to FIG. 13, the light housing 18 may be placed on the front surface 52 of the face plate 44 with the holes 22, 24 of the light housing 18 being aligned with the fastener holes 58, 60 of the face plate 44. The fasteners 26, 28 may be inserted through the holes 22, 24 of the light housing 18, through the fastener holes 58, 60 of the face plate 44, and guide by the guide walls 46, 48 to the pre-existing holes in the support surface 12. The fasteners 26, 28 may be fastened to sandwich the flange 34 between the light housing 18 and the support surface 12, thereby securing the mount 39 to the support surface 12.

The camera 40 may be pivotally attached to the mount 39, as shown in FIG. 14. The shanks 82, 84 of the camera 40 may be inserted into the shank holes 78, 80 of the bracket 38. The camera 40 may be pivoted to a desired angle that provides the best rearward field of view. In some embodiments, the camera 40 may be pivoted until it abuts the abutment 76 of the base 70 of the bracket 38.

The flow chart of FIG. 15 depicts the steps of an exemplary method 100 of securing a mount to a support surface of a trailer or other towed vehicle. In some alternative implementations, the functions noted in the various blocks may occur out of the order depicted in FIG. 15. For example, two blocks shown in succession in FIG. 15 may in fact be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order depending upon the functionality involved. In addition, some steps may be optional.

Referring to step 101, a light housing may be unsecured from the support surface of the trailer. A face plate removably attached to the light housing may be removed to gain access to fasteners inside the light housing and securing the light housing to the support surface. The fasteners may be unfastened and removed from the light housing. Light wires connected to the light housing may be spliced and connected to camera wires. The camera wires may be connected to a camera and extend through a wire hole of a bottom portion of the mount.

Referring to step 102, the light housing and a length of light wires extending from the light housing may be threaded through a light housing hole of the mount. The light housing hole of the mount enables the camera to be installed without having to disconnect any wires from the light housing. This reduces the complexity of the installation and obviates having to run wires through the trailer.

Referring to step 103, the mount may be positioned against the support surface. The flange of the mount may be placed on the support surface so that its exterior walls abut the support surface, thereby defining a cavity between a face place of the flange and the support surface. The camera wires may be positioned in notches on one of the exterior walls of the flange and extend through a hole in a bottom portion of the mount toward a bracket having a pair of protrusions for engaging the camera.

Referring to step 104, the light housing may be aligned with the mount so that one or more holes of the light housing is coaxial with one or more fastener holes of the mount. The flange may be positioned so that the fastener holes on the face plate are aligned with pre-existing holes in the support surface (the holes in which the light house fasteners were fastened prior to removal). The light housing may be placed on the front surface of the face plate with the holes of the light housing being aligned with the fastener holes of the face plate.

Referring to step 105, one or more fasteners may be fastened through the one or more holes of the light housing and the one or more fastener holes of the mount to secure the light housing and the mount to the support surface. The fasteners may be inserted through the holes of the light housing, through the fastener holes of the face plate, and guided by the guide walls to the pre-existing holes in the support surface. The fasteners may be fastened to sandwich the flange between the light housing and the support surface, thereby securing the mount to the support surface.

The method 100 may include additional, less, or alternate steps and/or device(s), including those discussed elsewhere herein. For example, the method 100 may include a step of attaching the camera. The camera may be pivotally attached to the mount via shanks of the camera, which may be inserted into shank holes in protrusions of the bracket. The camera may be pivoted to a desired angle that provides a desired rearward field of view. In some embodiments, the camera may be pivoted until it abuts an abutment at the base of the bracket.

Although the invention has been described with reference to the embodiments illustrated in the attached drawing figures, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims.
