Abstract

The lock with magnetic bolt has an internal cylinder rotating in an outer housing and with a keyhole, the bolt sliding in the transverse direction under the action of a magnet on the key. The bolt is accommodated in a recess in the cylinder (2), and its magnetic portion (13, 14) and that (15, 16) of the key (3) working with it are so arranged that their magnetic fluxes are at right angles to each other. In the locked position the flux centre lines can each be halfway between the outer ends of the magnetic portions. In the direction of movement of the bolt it can have two or more magnetic portions spaced apart in a non-magnetic portion of the bolt, corresponding portions being provided in the key.
