  • Patent number: 11346127
    Abstract: A lock has a hook and a locking finger to form a locking loop. The hook is fixedly attached to the lock body, whereas the locking finger can be pivoted to disengage from the hook to open the lock. The pivotal movement of the locking finger is controlled by a latch and an extended edge. The latch has a tip and the locking finger has a cut-out to receive the tip when the lock is locked. When the lock is locked, a spindle prevents the extended edge from moving toward the latch for releasing the tip from the cut-out. When the lock is opened by the combination mechanism, the spindle is moved away to allow the extended edge to move toward the latch to release the tip from the cut-out. When the lock is opened by the key mechanism, turning the cylinder causes the extended edge to move the latch downward.
