MAGNETIC LOCK Russian patent published in 1998 - IPC

FIELD: locking devices. SUBSTANCE: this relates to magneto-mechanical systems and particularly to locking devices with their power and control parts having permanent magnets. Lock has two systems of magnetic poles, each being made in the form of permanent magnets and is turned by its poles towards poles of other system. Both systems of poles can move relative to each other. One of systems with locking member secured on it is movable in direction of magnetizing of permanent magnets, and other system of magnetic poles which controls positioning of first system is movable in direction of permanent magnets located on it. Operation of lock is controlled by means of stopping devices with their components in the form of through or dumb holes, protrusions, etc. which are arranged on systems of magnetic poles. Closing of lock is obtained by releasing systems of magnetic poles from external connections applied to them by components of stopping devices. Opening of lock is effected by keys, and magnetic keys as well. EFFECT: high efficiency. 3 dwg
