发明名称 DOOR PIN REMOVER
摘要 <p>A tool for use with a hammer to remove the pin from a door hinge. The tool comprises an elongated cylindrical stem of circular cross-section, of a diameter sufficiently small to clear the opening at the bottom of the hinge, if such opening is present and, the inner surfaces of the pin receptacle of the hinge. One end of the stem terminates in a flat surface normal to the longitudinal axis of the stem. A head to receive the blows from an impact means is secured in offset fashion to the stem at its other end. The terminal, blow receiving surface of the head is normal to the longitudinal axis of the stem. The head has a circumscribing edge, and the head is secured near a segment of its edge to the stem in such a manner that a portion of the edge of the head in that area does not overhang the cylindrical surface of the stem. The portion of the head opposite the stem may be provided with a wedge-like shape, pointing away from the stem, with a central part of the wedge extremity being cut away in somewhat concave fashion to be used to wedge under and lift up the cap of a pin in a door hinge without slipping. Such tool facilitates removal of door hinge pins and reduces the potential for damage to walls and parts of the door surrounding such hinge, when compared to prior methods and devices for removing such pins.</p>
