ELECTROMECHANICAL LOCKING DEVICE (VERSIONS) Russian patent published in 2013 - IPC E05B47/06 

FIELD: construction.

SUBSTANCE: versions of electromechanical locking devices relate to electric locking instruments and devices of add-on type, designed for locking of doors, both within alarm control complexes and using separate control panels opening both inside and outside of a secured zone. Proposed devices comprises a lock casing including a bolt and a locking device with an electric motor. At both sides of the lock there are handles for bolt movement. In the first device there is a movable flange, on which there is a cam installed for movement of the bolt and a bushing with fixed spring-loaded brackets, in which levers are movably installed, interacting with movable brackets and having possibility of engagement with the cam, at the same time movable brackets are engaged with elastic, movable frames, interacting with helical grooves of bushings, fixed on shafts of electric motors. In the second device there is a movable flange, on which there is a cam installed for movement of the bolt and a bushing installed movably with a fixed spring-loaded bracket, in which a lever is movably installed, interacting with the movable bracket and having possibility of engagement with the cam, at the same time the movable bracket is engaged with an elastic, movable frame, interacting with a helical groove of a bushing, fixed on the shafts of the electric motor. In two locks positions of the door and bolt are tracked with electromagnet sensors. Casings of locks are made in dust and moisture-proof versions.

EFFECT: improved reliability of a lock.
