Abstract
The device for electromagnetically blocking the closing cylinder (2) of a lock (1) includes a rotary drive comprising a coil (12) and a rotor (7). Depending on the rotary position of the rotor (7), the movable tumbler (4) may be disengaged from the recess (3) of the locking cylinder. In the blocking position, disengagement is prevented by abutment on the end face (11) of the rotor. (FIG. 1 )
Claims8
