ELECTROMAGNETIC LOCK (VERSIONS) Russian patent published in 2015 - IPC E05B47/00 

FIELD: construction.

SUBSTANCE: electromagnetic lock relates to the field of security equipment, in particular, to locking devices, controlled by facilities of electronic equipment, having a function of automatic unlocking of unauthorised lock blocking, which actuates whenever the lock is blocked by a foreign object, inserted until stop into the lock hole with its subsequent withdrawal, and an alarm function that actuates in case of unauthorised unlocking of the lock by mechanical force or damage of a fixing control device, locked by the lock, and may be used for locking of the free end of the control device for fixation of a bicycle, a pram and similar vehicles on a parking lot for such vehicles, and also to lock doors of cabinets, safes, rooms. The electromagnetic lock comprises a body, a solenoid, a core, a fixator, a trap, balls, a cylindrical spring, a crossbar, between the inner surface of the body and the outer surface of the fixator there are contacts, one of which is permanently closed to the outer electroconducting surface of the fixator, and the other opens and closes by the outer electroconducting surface of the fixator as it moves, contacts and the inner end of the crossbar are connected by conductors to signal inputs of the control device of the electromagnetic lock. According to the first version, the core is magnetic, according to the second version - the surface near the body bottom.

EFFECT: expansion of functional capabilities of a lock, which makes it possible to use it at different objects of security equipment and saves from necessity to use sensors of door closure when using a lock for locking doors, improved operating characteristics, reduced power consumption, increased reliability of operation, lower noise of a lock, reduced weight and cheaper manufacturing of the lock.
