ABSTRACT:
A hitch unit for releasably attaching a towable vehicle to a towing vehicle or to a fixed anchor. This hitch unit has a modified ball unit for the attachment to a towing vehicle or to a fixed support. A singular bolt member is utilized to fasten the ball member in place, with this bolt member threadably passing through the ball member and extending beyond the operating surface of the ball member, terminating in an upper end. This upper end is provided with a transverse hole to accept a conventional locking device. The socket portion of the hitch unit is provided with a central opening in the dome of the socket to permit passage therethrough of the bolt member, with the size of the opening being sufficient to permit the socket member to pivot about the ball member through the degrees normally encountered in utilization of a hitch unit. Thus, the hitch unit of the present invention increases the safety of the hitch as well as preventing the unauthorization utilization of the towable vehicle.
