ABSTRACT:
The tongue or drawbar of a boat trailer is severed intermediate its ends; and the cut ends are then releasably hinged together by a pair of spaced, parallel hinge pins, either of which can be withdrawn to permit the forward end of the drawbar to be swung about the remaining pin, and rearwardly into an inactive position in which it effectively shortens the overall length of the drawbar, so that the associated trailer can be readily stored in a conventional garage. The hinge mechanism comprises a pair of tubular members designed to be slid over the cut ends of the drawbar, and then to be bolted and/or welded to the associated drawbar section. Confronting ends of the hinge members have thereon two sets of cooperating hinge barrels, which releasably support the two hinge pins about spaced, vertical axes adjacent opposite sides, respectively, of the drawbar. These tubular hinge members can be manufactured in various sizes so that they can be inserted onto drawbars of the most conventional sizes, e.g. 3".times.3"; 3".times.4"; and 3".times.5".
