ABSTRACT:
A trailer hitch facilitates coupling between a towing vehicle and a trailer where their respective coupling members are in close proximity, but not exact registration. The hitch is capable of being disengaged from a retracted locked position and of being moved forward relative to the trailer as well as in a lateral direction to permit ready coupling of the trailer and towing vehicle. After coupling is completed, the towing vehicle exerts rearward force against the hitch, causing the hitch to abut and be centered by a centering frame. An automatic latching mechanism completes the coupling by locking the hitch in retracted position. A back-up pin type lock precludes accidental uncoupling.
