LOCK Russian patent published in 2011 - IPC E05B47/00 E05B47/02 E05B47/06 

FIELD: construction.

SUBSTANCE: lock (1) comprises bolt (3), pusher (6), driving element (5). Pusher (6) is functionally joined to bolt (3) so that bolt (3) position is controlled. Driving element (5) is connected to pusher to transmit force that rotates driving element to pusher. Lock comprises electric motor (9), acting as source of power to change locking condition of lock. Pusher includes surface of force transfer (19B). Lock includes rotated lug of latch (8), having the first (19A) and the second (18A) of coupling surface. Lock also has facilities to transfer force/control (11, 12), which are functionally connected to electric motor (9) and to lug of latch (8). The first surface of coupling (19A) is arranged to enter in contact with surface of force transfer (19B), which makes it possible for coupling surface (19A) to control position of pusher (6) with the help of electric motor through facilities of force/control transfer (11, 12). The second coupling surface (18A) is installed into position of contact with driving element (5), making it possible to control position of pusher with the help of force that rotates driving element.

EFFECT: elimination of false alarm problem in case of ill-intentioned breakage of caps of ball handles of emergency exits, and accidental use of ball handle under regular circumstances.
