摘要： A padlock includes a lock body, a locking element movable between a locked position and an unlocked position, a latch, a user manipulable lock interface, an actuator mechanism, and a counter member. When the lock interface is operated to a sequence of N correct code entry conditions, the latch is moved from an initial locked position to an unlocked position. When the lock interface is operated to any one of the plurality of code entry conditions, the actuator mechanism engages the counter member and incrementally advances the counter member toward a stop position. When the lock interface is operated to a sequence of N code entry conditions in which at least one of the sequence of N code entry conditions is an incorrect code entry condition, the counter member is moved from the start position to the stop position before the latch can be advanced to the unlocked position.
