Abstract: A hitch pin retainer assembly that prevents unintended displacement of a shear pin from a trailer hitch includes a hitch plate assembly having a base plate formed with an aperture adapted to receive the shear pin assembly. The hitch plate assembly also includes a latch plate having a retainer ledge that carries a latch assembly that incorporates a receptacle projecting from the latch plate that captures a spring biased, slidable latch pin that is sized to extend, when in an extended position, above the shear pin. The latch pin is also formed with a handle at one end. The hitch pin retainer assembly can be either bolted or welded to an existing trailer hitch and also includes a tether that can be attached to the shear pin to prevent accidental loss.

Abstract: A bumper assembly for a motor vehicle includes a bumper structure having a bumper beam adapted for attachment to a structure of a motor vehicle such as a frame or rails, or the like. A hitch is attached to the bumper beam, and a bumper cover conceals the bumper beam. The bumper cover has an opening for accessing the hitch and an access door for selectively concealing the hitch. The access door is mounted to the bumper structure such that the access door will be retained upon the bumper structure not only when the access door is concealing the hitch but also when the access door is open to allow an accessory such as a trailer to be coupled to the hitch.

Abstract: The present invention consists of an improved device for aligning a vehicle trailer hitch to the coupling member of trailer. In one preferred embodiment of the device, a pair of vertical guide rods, one for the vehicle hitch and the other for the trailer coupling member, are provided with gimbal means so that the vertical guide rods remain perfectly vertical, regardless of grade or altitude of the vehicle hitch or trailer coupling member. The trailer hitch guide assembly is provided with a sleeve which may slidingly be received over a ball hitch. A counterweight is disposed at the lower end of the hitch's vertical guide rod. An elongate sleeve is place over the upper portion of the hitch's vertical guide rod and is held in place initially by a small notch located over the hitch ball. A second counter weight is provided for the lower end of the trailer coupling member's guide rod and the trailer coupling gimbal guide assembly is removably secured to the trailer coupling member by means of a magnet and an aperture adapted to slidingly fit over the coupling member. In such a manner, when the trailer hitch ball is in perfect alignment with the coupling member, the elongate sleeve will drop down several inches, revealing a brightly colored guide rod, indicating perfect alignment to the user of the device.
