  • Sliding towing assembly
    Patent number: 8220818
    Abstract: A hitch for coupling a trailer to a towing vehicle includes a hitch assembly and a base assembly. The hitch assembly pivots between an aligned position and a turning position as the towing vehicle turns. A bearing assembly rides between the hitch assembly and the base assembly. The bearing assembly guides the hitch assembly between the turning and aligned positions. The base assembly has an anchor assembly which prevents the hitch assembly from sliding fore or aft when in the aligned position.
