Abstract

The door protection system uses a paralysing gas. The gas is contained in a cylinder (17) which is fitted inside a cylindrical housing (20) bolted to the door frame (7). The gas cylinder valve (18) is kept closed by a pin (14). In the closed position of the door (2). The door catch (10) slides into a latch (6). Fixed to the door catch (10) is a forked shaped piece (11). This fork shaped piece slides under the head (15) of the pin (14). If an attempt is made to break open the door with the door lock (1) in the latched position, opening the door in the locked state will remove the pin (14) from the gas container (17). thus gas will escape from the container.
