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.
Claims14
A self aligning coupling device for connecting a towed vehicle to a towing vehicle comprising in combination a tongue support means including an integrally joined and spaced upper member, lower member and two side members, and further including inner wedging surfaces on at least said two side members, said tongue support means having two open ends, a planar tongue means freely slidably supported between said integrally joined and spaced members and protruding out of and beyond both of said two ends simultaneously during all operational sliding movements, said planar tongue means including notched wedging surfaces for engaging said inner wedging surfaces, inwardly biased detent means carried by said two side members to engage said notched wedging surfaces for locking said tongue support means and said planar tongue means together when said notched wedging surfaces and said inner wedging surfaces are fully engaged and means for mounting and means for coupling said self aligning coupling to one of said towed or towing vehicles.
