FIELD: operating or controlling locks or other fastening devices by electric or magnetic means. ^ SUBSTANCE: lock comprises blocking members displaced from remote location under the action of magnets arranged in key. Secrecy mechanism is protected against unauthorized opening by rotary head made of material having hardness and strength enough to increase time of criminal lock breakage resistance up to value exceeding that for high-class resistance to breaking-in governed by standards. Rotary head is secured to body having cylinder with pusher arranged inside thereof. Blocking members may move one by one in gaps between valleys of vertical corrugations formed on inner surface of cylinder bottom and protrusions of corrugations formed on pusher end. Pusher end corrugations are equidistant to that of cylinder. Depressions are formed in pusher end corrugation protrusions and are adapted for blocking member receiving during lock opening. Key with aligning magnets is inserted into rotary head hole from below in radial lock direction and connects with outer side of cylinder bottom. ^ EFFECT: possibility of lock usage for locking doors in buildings or vehicles, extended capabilities. ^ 15 dwg |
