摘要

An automatic door or window closing device which includes a tube (10) attached to the edge of a movable door or window. The tube (10) has a weight (20) displaced therein with a cable (12) attached at the top which passes out of the top of the tube (10) across a pulley (13) and is connected to the door or window jamb. A pneumatic seal (29) is provided between the weight (20) and the inside wall of the tube (10) and works in conjunction with a port and valve (30, 38) at the bottom of the tube (10) for controlling the flow of air passing therethrough. When the door or window is opened, the weight (20) rises in the tube (10). When the door or window is released, the weight drops in the tube according to the adjustment of the port (30) and valve (38) at the bottom of the tube, until the door or window is completely closed.
