Utility hitch
Abstract:
A utility hitch provides a shaft defining a longitudinal axis. A socket is affixed to the shaft and at least partially receives a ball. A slide lock coupled with the shaft is translatable parallel with the shaft longitudinal axis. A tongue protrudes from the slide lock. The tongue secures the ball into the socket by engaging the ball at a bottom surface, and alternatively releases the tongue from the ball bottom surface to enable the ball to release from the socket. Retracting pins protrude from the shaft to retain the slide lock and tongue in a first position immediately adjacent to the ball, and are operative to retract inside the shaft and slide lock when the slide lock is translated to a second position distal to the ball, to permit the slide lock to translate or reciprocate relative to the shaft. Wings may be provided to facilitate actuation of the retracting pins.
