Abstract

The lock has a bolt (2,3) which is shifted by handles on either side of the door, attached to a spindle (4). Movements of the bolt are controlled by two rotatable barrels (8) and (9) intersecting the profiled slots (10) and (11) in the bolt tail. In each barrel a pair of plungers (23) are sprung out into recesses in the surrounding lock body to block rotation of the barrel. Inward movement of the plungers to free the barrel is normally blocked by pairs of magnetic rotors (26A/26B, 26C/26D). To unblock the plungers a correctly coded magnetic key (Fig. 5) is inserted in the keyway (20) and the key and rotor magnets interact to turn the rotors into positions in which respective arcuate cut-outs (28) in the rotors align with the plungers (23). Turning the barrel now causes the plungers (23) to ride on inclined surfaces in the surrounding body thus pressing in the plungers and permitting rotation of the barrel. Barrel (8) is a "servant" barrel and barrel (9) is a "master". In Fig. 1 barrel (8) lies within a pocket (12) in the slot (10) to block throwing of the bolt. Turning it through 90 DEG permits the bolt to be single-thrown (to 2 min ) whereupon it is blocked against further extension by barrel (9) in pocket (15) and blocked against retraction by barrel (8) in pocket (14) when (8) is rotated back to its locked position. Turning barrel (9) through 90 DEG now permits the bolt to be double-thrown (to 2 min ) whereupon it is blocked against retraction by barrel (9) in pocket (17) when the latter is rotated back to its locked position. Retraction of the bolt involves the reverse sequence.
