ABSTRACT:
A door bolting device for use with a door which has an empty cylinder hole and which is mounted in a doorframe having a doorjamb against one side of which a first of the door's two broad sides abuts when the door is closed. The device comprises a door-grabbing element which abuts against the second of the door's two broad sides; a jamb-grabbing element which abuts against the opposite side of the doorjamb from that which the door abuts when closed; and a connecting element which connects the door-grabbing element on the second broad side of the door to the jamb-grabbing element on the first broad side of the door through the cylinder hole, so that the door is held against the doorjamb. In a preferred embodiment, the door-grabbing element abuts not only the second broad side of the door but also a portion of the doorframe, and the jamb-grabbing element has a grabbing portion abutting against the doorjamb, a door-adjacent portion lying adjacent to the side of the door with an opening positioned over the cylinder hole, and a jamb-front abutting portion extending adjacent to a front surface of the doorjamb located between the door and the grabbing portion of the jamb-grabbing element. In such a preferred embodiment, the connecting element extends from the door-grabbing element through the cylinder hole and the opening in the door-adjacent portion of the jamb-grabbing element, and includes an attaching element to prevent the door-grabbing element and the jamb-grabbing element from being pulled apart. In one preferred embodiment, the connecting element includes a threaded bolt and a nut and a washer which have been threaded onto that bolt and welded in place.
