Magnetically actuable safety apparatus for preventing unauthorized actuation of a touch-operable device

摘要

An apparatus for selectively blocking movement of a part of a device employing said apparatus which is particularly useful in preventing the unauthorized firing of a weapon or removal of screw caps or operation of other touch actuated devices. The apparatus typically comprises a magnetically actuable member mounted to a resilient material which material is mounted to the device for selectively disposing the magnetically actuable member in a conflicting relationship for blocking movement of the part. Magnetic means is provided from without the device and juxtaposed the magnetically-actuable member for attracting or repelling the member out of the blocking relationship with the part whereby the part is free to move.
