CODE MAGNETOMECHANICAL LOCK Russian patent published in 2003 - IPC

FIELD: protective means. SUBSTANCE: the lock has a separator with movable magnetic components (MMC), located on the opposite sides of the separator and along it are perfoframes with grooves for the magnetic components, holder with fixed magnetic components located coaxially with the movable ones and facing them with the like poles, and a key for engagement with the magnetic elements. The perfoframes are made in the form of square plates fixed in the grooves of the cross-piece with two guide holes for translational motion of the rods through them rigidly coupled with the separator body. The cells in the separator and the grooves in the perfoframes are located in the form of matrix nxm, where n - the number of the cells in the vertical, m - in the horizontal. By screw joint the separator is rigidly coupled with the holder through four separating bushes providing a gap between them for free movement of one of the perfoframes in it. Placement of the key in the place marked on the face panel of the door results in the fact at a properly adjusted code combination of the magnets that the MMC start moving under the action of their magnetic power field. The MMC, coming out of the grooves and moving in the opposite direction from them, stop against the smooth surface of the perfoframe. The MMC, which in the initial state was out of the groove, remains in place. In the given position the MMC nothing prevents the motion of the perfoframe in the vertical plane along the separator. The force applied by means of the locking lever of the actuating device to the cross-piece surface results in its lowering along the guide rods. The actuating device operates, the door opens. EFFECT: enhanced degree of secrecy of the lock and key. 2 cl, 4 dwg
