ABSTRACT:
A proximity hitch can be fitted to a towed vehicle, as for example a trailer, so that the trailer can be towed by a towing vehicle. The hitch comprises opposed main frame members which terminate in a flat mounted plate. A guide member is pivotally attached to the mounted plate and reciprocatingly receives a tongue therethrough. The tongue has a socket formed at one end thereof and a cam follower at the other end thereof. Opposed cam plates have confronting cam surfaces formed thereon with there being a notch formed between the cam surfaces. The cam follower is received within the cam notch when the proximity hitch is retracted. The cam follower rides against the cam surface as the socket is moved over a wide area of movement. The tongue and guide member are latched into a retracted position when the trailer is to be towed and unlatched when it is necessary to connect the trailer to the towing vehicle.
