ABSTRACT:
A self aligning hitching device having a tongue support mountable on a vehicle or vehicle hitch. The tongue support has a mounting support so that the tongue support can easily be mounted on a vehicle. A tongue is provided that is mounted in the tongue support and is slideably free floating when in the unlocked position. It is at this time the connection is made between the towed & towing vehicles. Both the tongue and tongue support have wedging surfaces that guide the tongue now connected to a wedged or fully seated position at which time a spring biased locking pin secures them both together so that a towing vehicle carrying the tongue support and a towed vehicle connected to the tongue are now joined and ready for a towing movement.
