ABSTRACT:
A hitch pin for connecting a drawn vehicle to a towing vehicle. The hitch pin includes a pin having a lower end and a transverse collar near its upper end, a handle mounting member extending upwardly at the upper end, and a handle pivotally connecting to the handle mounting member at an axis. The handle includes a pivot portion having a locking lever biased from pivoting downwardly and a latch portion. A first embodiment of the present invention includes the handle mounting member having two opposing flanges with flat inner surfaces and the pivot portion having flat sides such that pivot portion pivotally connects to the mounting member with the sides respectively facing the inner surfaces. A second embodiment thereof includes the handle mounting member having flat sides and the pivot portion having two opposing flanges with flat inner surfaces such that pivot portion pivotally connects to the mounting member with sides respectively facing the inner surfaces. When the handle connects to the handle mounting member, the locking lever engages a notch formed on the handle mounting member and the latch portion engages the lower end of the pin, defining a locked position of the hitch pin. When pressure is applied downwardly against the locking lever, the locking lever pivots downwardly such that it clears the notch, disengaging the latch portion from the lower end and allowing pivotal movement of the handle about the axis.
