摘要： The lock has a hook, a locking finger and a latch. The locking finger is engaged with the hook and the latch when the lock is in the locked mode. The locking finger is disengaged from the hook and the latch when the lock is in the opened mode. The lock can be opened by a combination mechanism or by an overriding key mechanism. The combination mechanism has a button, and a plurality of dials and clutches to control the movement of the button. When the dials are set to a correct combination, the button can be moved to disengage the latch from the locking finger, allowing the locking finger to disengage from the hook. The key mechanism has a cylinder with a key slot to receive a key for rotating the cylinder to disengage the latch from the locking finger, allowing the locking finger to disengage from the hook.

摘要： A padlock including a lock body, a combination mechanism to control movement of a spindle within the lock body, at least one clutch mounted about the spindle each clutch having at least one extended-fin, and alignment of each of the at least one extended-fin with a corresponding gate in the lock body allows for movement of the spindle within the lock body. The padlock may also include a shackle having a long leg and a short leg, and the padlock is positionable between a locked mode in which the short leg of the shackle is positioned within the body and the movement of the spindle within the lock body is substantially limited, and an unlocked mode in which the short leg of the shackle is spaced apart from the body and movement of the spindle within the lock body is allowed.

摘要： A combination padlock comprising a body, true gates, a locking ball, a spindle and a plurality of clutches and dials, a shackle which contains a neck, a locking bolt with a neck, the spindle to control the lock opening of the locking bolt and control the alignment of the true gates of the clutches, the plurality of clutches to prevent the lock from being opened when the dials are not in a locked opened combination, the clutches having extended fins with rounded edges, and the plurality of dials to control the rotational movement of the clutches, so that when the extended fins of the clutches are fully aligned with the true gates, a user can pull a knob-side of the spindle to the right so that the neck of the shackle forces the locking-ball to move upward away from the neck of the shackle so as to unlock the padlock.

摘要： A combination lock has a body formed from a stack of plates each having various openings to form some of the channels or holes such as the locking hole to receive the short leg of the shackle, the long-leg channel, the spindle hole, the dial slots, the ratchet-pin holder slot and the bolt slots. The short leg and the long leg of the shackle each has a cutout to receive a locking bolt. The spindle has a locking surface to engage the locking bolts with the cutouts when the lock is in locked mode. The spindle also has a neck to release the locking bolts from the cutouts when the lock is in opened mode. The lock has a directional plate and a reset button near the lock's bottom end to control the rotation and the downward movement of the spindle in the reset mode.
