CODE MAGNETOMECHANICAL LOCK Russian patent published in 1997 - IPC

FIELD: locking devices applicable in residential and public buildings and characterized by the absence of lock hole, and possibility of multiple rearrangement of key code and lock. SUBSTANCE: code magnetomechanical lock body has circular recess and grooves and socket key has projections by pairs with shapes and sizes similar to grooves for possibility of its tight pressing to holder to provide for rotation in circular recess with holder. Locking rods have bend but not in the zone of their installation in holder plate. Power magnets of matrix and socket key are inherent parts of magnetic circuit localizing their induction magnetic fluxes. EFFECT: higher efficiency. 2 dwg
