ABSTRACT:
A vehicle tow bar includes a transverse cross member which mounts one pivotal, elongated leg assembly in fifth position at one end of the cross bar and a second pivotal, elongated leg assembly for movement across the cross bar between a collapsed condition closely adjacent the first leg assembly and an erected, operative position at the opposite end of the cross member. The ends of the leg assemblies opposite the cross member are connected to an apex frame which mounts a socket coupler component of a ball and socket type trailer hitch. Each leg assembly includes telescopic sections for adjusting the length of the leg assembly. A spring loaded locking piston in one leg section of each leg assembly is arranged, when the leg sections are extended, to project into a locking socket in the other leg section of the leg assembly, to secure the leg sections in extended condition. A spring loaded release plunger in the locking socket functions by finger pressure to retract the locking piston from the socket when it is desired to retract one leg section into the other. Flexible protective boots are provided about one of the telescoping leg sections of each leg assembly to protect the telescoping section against the deleterious effects of the surrounding environment and to contain lubricating grease and the like for constant lubrication of the telescoping leg sections.
