Abstract

See full text

A padlock is provided that can be locked and unlocked using a combination mechanism or a key mechanism. A padlock includes clutches that will not be turned during the lock mode or the open mode. A lock body has more than one slot to engage an extended fin of the clutch in the lock mode. An opening slot and faulty notches are located in each of the dials. In the lock mode, the turning of the dials will have no effect on the clutches. Each extended fin of the clutch is engaged in a slot of the lock body in the lock mode. The faulty notches on the dials are clearer and an intruder cannot feel the correct opening slot by turning dials to pick the combination.
