ABSTRACT:
A novel latch mechanism for a trailer hitch assembly used to interconnect a towing vehicle to a drawn vehicle. The hitch assembly includes a frame, mounted on the towing vehicle, having an upwardly extending pintle and a cavity disposed adjacent the pintle for receiving the coupling element of the drawn vehicle; a spring-biased, pivotally-mounted latch extending over the frame cavity, having a notch and a ledge disposed adjacent its forward end; and a spring-biased, pivotally-mounted pawl, generally overlying the latch, having a cam disposed adjacent its forward end and its rear end adjacent and in seated relation in the notch of the latch. In the apparatus of the invention the latch is held securely in place by the cooperating action of three different safety features: the pawl spring urges the rear end of the pawl downwardly into seated relationship in the latch notch; the pawl cam and an opposing cam-engaging surface on the latch disposed adjacent the cam prevent lateral displacement of the latch; and the latch ledge and an opposed shoulder on the frame prevent pivotal movement of the latch, without axial displacement.
