FIELD: mechanisms.SUBSTANCE: invention relates to locks, wherein locking element is bolt, which is in kinematic link with secrecy mechanism. Lock comprises housing and bolt installed in it to perform main motion for locking and unlocking, and secrecy mechanism to secure main movement of bolt. Lock has also at least one additional drive, which provides at least one additional movement of bolt for locking and unlocking kinematic link between bolt and secrecy mechanism. In another version, bolt consists of first part of bolt, and at least one second part of bolt in kinematic link therewith; locking and unlocking of lock is performed by first part of bolt. Security mechanism provides main movement of bolt by transmitting bolt first part movement onto at least one second part of bolt, and at least one additional drive allows opening and closing kinematic link between secrecy mechanism and at least one second part of bolt.EFFECT: technical result is increase of secrecy level of lock.6 cl, 15 dwg |
