Abstract
A hitch for use in coupling a trailer to a towing vehicle characterized by a housing having bottom and top plates disposed in mutually spaced parallelism and a pair of converging side walls defining on opposite sides of the housing a first and a second throat disposed in coaxial alignment, said first throat being of a width dimension less than the width dimension of the second throat, an extensible link comprising a coupling arm seated between said plates having a width dimension slightly less than the width dimension of the first throat and projected from the second throat, a slot of a keyhole configuration comprising an elongated segment terminating in a bore, a retainer pin normally related to the plates and extended through the slot supporting the link for displacement to a retracted position wherein said link is extended through the first throat, and a cylindrical interlocking bolt integrally related to the retainer pin and configured to be inserted into the bore when the link is displaced to its retracted position for securing the link against displacement from its retracted position, whereby the link is supported against both axial and pivotal displacement.
