ELECTROMAGNETIC LOCK Russian patent published in 2009 - IPC E05B17/20 E05B47/02 

FIELD: construction.

SUBSTANCE: invention relates to hardware products, namely to locking devices, and deals with electromagnetic locks containing bar, which interacts with catcher being inside the lock and shaped as a cup. The catcher is implemented as a cylindrical bushing and located coaxially to fixing element capable of displacing in longitudinal direction. Electromagnet with core and ball-type locking mechanism are also available in the lock. In addition, the lock is provided with a permanent magnet and catcher is installed between lock housing wall and fixing element. It is represented as a bushing with faceted ends.
