ABSTRACT:
A hitch for mounting on the back of a vehicle for towing a trailer or other equipment. A ball is mounted on the extended end of a hook portion of the main hitch body and is adapted to receive either a lunette or hooded-type coupler thereon. A closure latch is pivotally mounted on a rear portion of the hitch body and is engageable with the ball when securing a lunette coupler on the hitch and is alternately engageable with the hood of a hooded coupler when securing such a coupler on the ball. A spring-biased first locking pawl is pivotally mounted on the closure latch and is clamped against a shoulder on the hitch body by a spring to lock the latch in closed position with a hooded coupler. A second locking pawl is pivotally mounted on the first locking pawl and is clamped against the shoulder by the spring to lock the closure latch in engaged position with the hitch ball when securing a lunette coupler thereon. Both locking pawls can be disengaged from the shoulder to permit the closure latch to be moved to an open position for coupling and uncoupling either type of coupler with the ball.
