MAGNETIC LATCH Russian patent published in 1994 - IPC

FIELD: fixing of flaps, locking of instruments and cabinets. SUBSTANCE: magnetic latch has two permanent magnets of ring shape to fulfil lock functions. Magnets are fastened to components coaxially and facing each other with unlike poles. Core in form of ball is installed inside holes of permanent magnets with gap. Control member is attached to one of components for interaction with ball. Components are installed for motion in plane square to magnet axis. In initial position of components, the core hinders mutual motion of connected components. When position of core along magnet axis changes by means of control member, the effect of wedging of magnets by core alternates by their unwedging and possibility of mutual motion of components. EFFECT: higher efficiency. 2 dwg
