Abstract
A trailer hitch guide constructed in accordance with the present invention mounts a base upon the vehicle hitch and a pair of detachably, mountable, lateral guides are attachable to the base for projecting rearwardly therefrom. A first cam surface is provided which is connectable to said base and a second cam surface is connectable to the trailer tongue. The first and second cam surfaces are formed to cooperate to cause relative vertical displacement between the vehicle hitch and the trailer tongue as the vehicle hitch approaches the trailer tongue. The trailer tongue is aligned in a horizontal plane and raised in a vertical plane during the approach until the socket on the trailer tongue is positioned over the ball hitch. The trailer tongue is then dropped upon the ball hitch engaging the socket over the ball. The lateral guides and cam surfaces are removable as necessary to facilitate freedom of angular movement between the trailer hitch and the trailer tongue.
