Remotely operated door lock - has electromagnet separating door handle from latch release mechanism in one position

摘要

The lock includes an operating handle (9) and a latch bolt (6). Between these is a mobile finger (8) carried by a push-rod (10). The push-rod is operated by an electromagnet (15). In one of its positions, the mobile finger ensures that there is no connection between the handle, and the latch bolt. Movement of the electromagnet re-establishes the connection. A spring (11) urges the mobile finger in one direction. The connection between the handle and the mechanism is provided by a gudgeon pin which is withdrawn from the handle in the disconnected position. ADVANTAGE - Door lock may be remotely released.
