ABSTRACT:
A jointed two bar for towing one vehicle by a second vehicle which incorporates joints in such a way as to allow folding and imprecise alignment during attachment, but a fail safe rigid structure for towing. A rotating cross bar joint on beams can be lifting out of the fixed towing position for storage or attachment but is prevented by structure from downward movement. Lateral movement of beams can also be accomplished from a pivot joint after beams are lifted out of a keyed slot. In towing position, slots and structure prevent folding movement from tensile, compression or lateral forces. When not in use, tow bar can be tipped up and folded on front of towed vehicle or removed and conveniently carried to a trunk of a vehicle.
