SAFETY MECHANISM FOR LOCKS

摘要

In a security device for locks comprising a grip portion or knob (1) which is freely rotatable in the resting state and can be coupled to the locking member (7) of the lock in the open or closed state, a radially guided displaceable flyweight (13) is coupled to the grip portion or knob (1), which engages with a fixed portion (11) of the lock (12) and blocks any further rotary movement above a defined number of revolutions of the grip portion or knob (1) per unit time.
