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.
