ABSTRACT:
The trailer hitch has a base frame adapted to be carried by a vehicle and a hitch frame adapted to engage the base frame. A power liftable actuator is attached to the base frame and the hitch frame for raising and lowering the hitch frame to engage the tongue of a trailer. A vertically arranged connecting pin is also attached to the hitch frame and is adapted to be moved in a vertical path of travel from an elevated uncoupled position to a lowered coupled position. A power operable actuator is connected to the hitch frame and the connecting pin for moving the connecting pin from an elevated uncoupled position to a lowered coupled position. In addition, the trailer hitch has a horizontally swingable tongue guide positioned alongside the connecting pin and the hitch frame. The horizontally swingable tongue guide is adapted to guide the tongue of a trailer into proper position for being connected by the connecting pin. The horizontally swingable tongue guide includes a pair of guide plates convergently arranged that define an angle therebetween with the vertex of the angle being closely adjacent the path of travel of the connecting pin. Also, a spring is used to resiliently mount the pair of guide plates for unison horizontal swinging movement to thereby facilitate the guiding of the trailer tongue toward the vertex. A scoop is mounted vertically below and adjacent the horizontally swingable tongue guide for scooping the trailer tongue from the ground for engagement with the connecting pin.
