An exemplary lock apparatus generally includes a shackle, a crossbar, a lock device, a first bolt, and a trigger. The lock device has a locked state in which the lock device retains a spindle in a spindle locking position, and an unlocked state in which the lock device does not prevent movement of the spindle to a spindle unlocking position. The first bolt is engaged with the spindle such that movement of the spindle between the spindle locking position and the spindle unlocking position drives the first bolt between a first locking position and a first unlocking position. The trigger is movably mounted in the crossbar for movement between an engagement position, in which the trigger maintains the spindle in the spindle unlocking position, and a disengagement position, in which the spindle is operable to move to the spindle locking position.

Disclosed is a combination lock, comprising a rotatable knob capable of relative rotation, a panel, a bolt, and a dial assembly. The dial assembly comprises a base having a movement chamber, a dial shaft, multiple sets of bushings and dials, a position resetting mechanism, a positioning member, and a protection frame The rotatable knob can be rotated relative to the panel to a first position, second position, third position, or fourth position, so as to achieve locking, automatic password resetting, automatic dial position resetting, and manual password setting. The combination lock uses one-time temporary passwords, thereby achieving superior security performance.

The present invention discloses a flippable cable lock with a twistable cable capable of being twisted into an X-shape cross state and remains in that state. In addition, the cable lock further includes a combination lock mechanism, an elastic member and a key lock mechanism. The elastic member includes a plurality of arc-shape elastic sheets engaging with multiple dials of the combination lock mechanism. The key lock mechanism includes a blocking portion and a push portion. When the key lock mechanism is unlocked, the blocking portion leaves from blocking a lower-section of the twistable cable, and the push portion pushes the lower-section to move.

The present invention discloses a combination lock mechanism for a lock, it includes a plurality of dials and an elastic member, each dial has a plurality of blocks and a plurality of grooves, each block has an identification element respectively, each groove is located between two adjacent blocks, the elastic member is located beside the combination mechanism and having a basic sheet and plurality of elastic sheets, each elastic sheet is connected to a side of the basic sheet, and each elastic sheet has a protruding portion on both ends respectively, each protruding portion can be lodged into each groove of the dial.

An object padlock comprising, an object looking cover/body shape, at least one dial to control the opening of the lock as a primary control mechanism which is said to be a combination mode, a locking means such as a cable with one end always in the padlock and the other end such as a flexible-end can be locked and opened via a combination dial control, and at least a cylinder to control the opening of the lock as a secondary control mechanism which is said to be unlock by key mode.

The present disclosure is directed to a combination lock including a housing configured to lockingly receive a locking link. The lock includes a plurality of outer dials and a plurality of inner dials, each selectively coupled to a corresponding outer dial. A spindle is positioned radially internal to the inner dials. A multiplier link is pivotably connected between the spindle and a locking bolt. Some forms of the combination lock include a tactile feedback mechanism and/or a combination reset mechanism.

An example lock apparatus includes a shackle including an engagement portion, and a lock head operable to selectively engage the engagement portion to thereby retain the lock apparatus in a closed condition. The lock head includes a housing, a slider, and a detent mechanism. The slider is mounted for sliding movement relative to the housing between a first position and a second position. One of the first position or the second position is a closed position in which the slider prevents removal of the engagement portion from the lock head, and the other of the first position or the second position is an open position in which the slider permits removal of the engagement portion from the lock head. The detent mechanism is configured to selectively resist movement of the slider from the first position.

A zipper lock has two locking members to secure two zipper pulls of a suitcase and a control plate to cause the locking member to disengage from the zipper pulls. The lock has a latch engaged with the control plate, the latch positionable in a first latch position when the lock is in a locked mode or in a second latch position to open the lock. The lock has a combination mechanism using dials and clutches to control the movement of a spindle which allows the latch to move the second latch position when the arrangement of the dials matches the correct combination code. The lock also has a key-overriding mechanism using a cylinder to cause the movement of the latch when a correct key is used to turn the cylinder to open the lock. A recovery mechanism allows a user to recover the lost combination code.

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.

Provided is a combination lock including a housing having an lodge port configured for removably receiving therein a shank; a locking bar received within the housing and having a shank port; a combination mechanism associated with the locking bar; and a securing arrangement including an arresting member of the locking bar.
