Abstract (en)
A mechanism for preventing picking of a combination lock comprises a sensor 11 for sensing the number of revolutions or partial revolutions of the shaft 4 of the combination lock within a given time period. The combination shaft 4 of the lock is provided with a toothed or cammed wheel and with a pivotably mounted lever arm 6. A first free end 8 of the arm is adapted to engage the toothed or cammed wheel 5 and a second end thereof is movable through the selectively applied attraction from an electromagnet 10 to lock the combination shaft 4 when it is determined that the combination wheel is being tampered with. <IMAGE> <IMAGE>
