MAGNETIC LOCK Russian patent published in 2010 - IPC E05B47/00 

FIELD: construction.

SUBSTANCE: invention relates to locking devices, in particular to magnetic code locks. Magnetic lock comprises magnetic block having race with fixed magnetic elements, separator having movable magnetic elements located on top and rigidly joined with the race, and its magnetic elements are installed coaxially to fixed identical magnetic poles facing each other. Seat for key is located between race and separator. Key is arranged in the form of plate-punch card from soft magnetic material with holes for interaction with magnetic elements. Lock comprises a control handle connected to separator by means of blocking device that comprises friction coupling, lever and spring-loaded stem, which is rigidly connected to punch cards. In separator there is a through cavity equipped with spring-loaded universal punch frame movable in longitudinal direction with holes for heads of code (non-code) elements, changing into slots for grooves of code (non-code) elements heads, and side ledges for interaction with reverse mechanism via control handle. In separator holes there are differential blocks installed from magnetically controlled inverted cylindrical heads with grooves displaced along diametre from center of cylindrical surfaces of heads and magnetic elements that control cylindrical heads and are arranged coaxially to fixed magnetic elements of race with identical magnetic poles. Depending on height of grooves arrangement in process of inversion, heads perform functions of code (non-code) elements, end parts of which rest against removable cover installed on upper plane of separator, which makes it possible to perform coding (recording) without necessity of dismantling. Seat for key is arranged as through, is provided with movable support-stabiliser of key position, having side ledge that interacts with movable support as key is inserted into seat to provide for matching of key perforations centres with axial lines of controlling magnets with double-sided (from external and internal sides of door) control, as key is placed into seat on the opposite sides with their end surfaces.

EFFECT: invention makes it possible to increase reliability of lock and expand its functionality.
