Patent ID: 6945553

Claim:
A hitch assembly that permits an operator to pressure couple a towable vehicle to a towing vehicle while the operator remains in the cab of the towing vehicle, said hitch assembly comprising a towing hitch arrangement on the towing vehicle and a towed hitch arrangement on the towable vehicle, wherein said towing hitch arrangement consists essentially of a basic ball hitch and a vertically orientable hydraulically operated ram assembly having a hydraulic ram equipped with a rubber pressure stub at its lowermost end in an orientation above said basic ball hitch for hydraulic movement of said rubber pressure stub vertically toward and away from said basic ball hitch, and wherein said towed hitch arrangement consists essentially of an inverted cup-shaped socket for coupling on said basic ball hitch, said socket having an upper outer surface, said ram's rubber pressure stub being adapted to be vertically moved toward and pressed against the upper outer surface of said inverted cup-shaped socket to hold said cup-shaped socket on said basic ball hitch without scratching said upper outer surface regardless of the contour of said upper outer surface and regardless of pivot movement of said upper outer surface against said rubber pressure stub during towing operations, there being no need for any tightening of the cup-shaped socket to form a grip about said basic ball hitch, whereby the direct vertical application of pressure by said rubber pressure stub on said upper outer surface of said cup-shaped socket constitutes the sole feature for holding said cup-shaped socket against separation from said basic ball hitch.
