    Abstract: The present invention comprises a trailer hitch system, for attaching a trailer to a vehicle having a winch attached to the frame of a vehicle, a hollow receiver attached to the frame of a vehicle, where the receiver has a receiver opening, which is defined by a top guide, bottom guide and at least two side beams. The winch wire attaches to the winch, travels through the receiver, out of the receiver opening and attaches to a hitch bar at a tab. When the winch is activated the winch wire pulls hitch bar and thus, the attached trailer, into the receiver opening. A bearing located on the forward facing side of the hitch bar reduces friction between the hitch bar and the receiver as the hitch bar enters the receiver opening.

  • Patent number: 6634666
    Abstract: An adjustable trailer hitch which provides an operator improved remote control of the lateral position of a trailer hitch, and simplifies the procedure of hooking a trailer to a tow vehicle. The trailer hitch comprises a hitch assembly (such as a ball receptacle) attached to a roller carriage which moves from side-to-side along a bumper-like housing. The roller carriage engages a positioning screw, and an electric motor mounted in a sealed end cap powers the positioning screw. Rotation of the screw translates into rightward or leftward lateral movement of the roller carriage and consequently of the ball receptacle assembly. Motion of the ball receptacle assembly is controlled via a wireless remote control unit. Such direct control over the precise lateral position of the trailer hitch enables the operator to accurately steer the trailer when traveling in reverse.

    Abstract: An improvement in or relating to a hitch assembly for connecting a trailer to a towing vehicle. The hitch assembly consists of features which are moveable in a telescopic manner and/or in a rotational manner to allow the adjustable repositioning of a coupling member of a trailer for it to be conveniently connected to a tow ball of a towing vehicle. The hitch assembly consists of ratchet type features that when a movement of the trailer is provided by the towing vehicle, the hitch assembly will move towards a condition, substantially automatically, where the connection between the trailer and the vehicle becomes substantially rigid apart from the degrees of freedom of movement normally provided by the coupling. The ratchet type features can be made in operative to allow for a user to manipulate the position of the tow coupling of the trailer so as to achieve a coupling between the trailer and the tow vehicle without the trailer needing to be in an exact location in respect of the tow coupling of the trailer.
