MORTISE CYLINDER MAGNETOMECHANICAL CODED LOCK Russian patent published in 2002 - IPC

FIELD: locking devices characterized by absence of keyhole, and possible multiple readjustment of key code and lock. SUBSTANCE: installed in body of combination mechanism is spring-loaded head consisting of rod with cross-section in the form of regular hexagon having bore and running through hexagon hole of support and connected to hexagon is flange from magnetic permeability material with projections on its external side and freely rotating ball located in place connection. Body of combination mechanism has external flange in the form of unsymmetrical geometric figure and internal flange with two projections (or one of them) of head flange lean against it. Bases of said projections are facing head flange axis and follow configuration of respective projections (projection) of internal flange. Rod head and inserts in the form of regular hexagons rounding it are tightened over periphery with the help of spring. Magnetically soft bodies of rotation serve as interlocking members of combination mechanism. Base of socket key follows in plane shape of cutout of internal flange of combination mechanism body. EFFECT: sufficient high protection of lock combination mechanism against unauthorized opening. 7 dwg
