ABSTRACT:
A portable collapsible door stop and holsters for supporting door stops and for attaching the holsters to hand trucks. The preferred embodiment of the door stop includes two main rectangular plates hingedly attached to one another at one end. Third and fourth plates hingedly attach beneath one of the rectangular plates having their opposite ends which are received in recessed grooves in the upper surface of the other main rectangular plate. The collapsible door stop has a side mounted clip for holding the door stop in a shirt pocket. The holsters include open topped boxes wherein the angled portion of wedge shaped door stop are inserted therein. Hinges formed from coiled springs or bent metal strips compress and fixably hold the door stops inside of the box. Expandable side clips allow for the holsters to be attached to the legs and bars of a hand truck or dolly. The boxes can be sized to allow plural door stops to be positioned therein. The collapsible door stop and the holsters can be formed from aluminum. Alternative embodiments include building the holster into the existing hollow side frame leg of a handtruck by attaching a pin or plate across the interior opening of the side frame leg. Alternative embodiments further include using the holsters to support clipboards on the cross-brace bars of the handtrucks.
