ELECTROMECHANICAL LOCK Russian patent published in 1997 - IPC

FIELD: guard equipment, particular locking devices. SUBSTANCE: electromechanical lock has body accommodating locking cross bar which is connected with connecting rod by means of hinge. Connecting rod is hinged with turning disk which is turned on its own axle by exterior cylinder mechanism. Turning disk has stop for interlocking the turning motion to the side of opening by electromagnet armature which is spring-loaded to the side of lock opening. Armature motion to the side of opening is limited by screw. In locked position the electromagnet armature is held by the fixing device of turning disk and pressed to stop of electromagnet. Limit switch is kinematically connected with turning disk by means of connecting rod and operates when turning disk is turned to the side of locking through the angle insufficient for electromagnet armature to come out of locking device of turning disk. Electromagnet pusher, when disk is turned to the side of locking through angle sufficient for electromagnet armature to come out of locking device of turning disk, starts mechanically pressing the armature to stop of electromagnet. EFFECT: higher efficiency. 2 dwg
