1. A hitch for coupling a trailer to a towing vehicle comprising a shoe adapted to be carried by the trailer for limited rotation relative to the trailer about any axis, said shoe comprising a polygonal-shaped plate having one edge at the rearward end of the plate relative to the direction of travel of the vehicle and a pair of convergent edges facing generally laterally of the vehicle with their converging ends toward the front of the vehicle, means including a bed plate adapted to be secured to said vehicle for receiving said shoe, said shoe being slideable on the bed plate on a line extending in the direction of travel of the vehicle between an unhitched position in which the shoe is clear of the receiving means and a hitched position, said receiving means comprising a pair of abutment members disposed on opposite sides of said line, each abutment member having a vertical edge for engagement with a respective convergent edge of said shoe plate thereby to prevent movement of the shoe plate in one direction along said line and laterally thereof when said shoe plate is in its hitched position and holddown means for overlying portions of said shoe when the latter is in its hitched position to prevent any substantial upward movement of the shoe, and a locking bar axially slidable on the bed generally perpendicular to said line to and from a locking position in which said bar is engageable with said one edge of said shoe plate for preventing movement of the shoe plate from its hitched position along said line in said other direction and means on said bed plate for mounting said locking bar for sliding movement to and from its locking position.
