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.

A lock has improved protection against lock picking. The lock comprises plural tumblers, each generally cylindrical in form with outer and inner circumferential edges, all the tumbles arranged on a common axis. The outer circumferential edge of each tumbler having a single true gate, including a void extending a predetermined distance toward the axis and plural false gates, each having a void of lesser extent. Ridges separates the true gate from adjacent false gates, and separate adjacent false gated from each other. The lock also includes a sheath contacting the inner circumferential edges of the tumblers. The sheath includes ridges located to maintain the tumblers in contact with each other.

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.

Aspects of the present disclosure may relate to a bag having a retractable lock unit that may simultaneously prevent theft of the bag and theft of its contents. The bag may include the retractable lock unit which can be secured to the bag, a zipper system having a pair of zippers, and a locking ring. In some aspects, a user may draw the lock unit from its housing to the pair of zippers and lock the pair of zippers together so as to prevent the bag from being opened. In this way, the bag may provide additional security for the contents while the user has the bag on their person or near themselves. In other aspects, the user may draw the lock unit from its housing around one or more objects before securing it to the locking point and/or a pair of zippers. In this way, the bag may be securely anchored to the one or more objects thus preventing theft of the bag itself as well as preventing theft of the contents.

A lockable enclosure includes a housing and an access door assembled with the housing and movable between a closed position and an open position. A latch is carried by the access door and is slideable along a first axis between a door latching and a door releasing position. A plurality of dials are carried by the access door and rotatable about a post extending along a second axis. When each of the plurality of dials is rotated to an unlocking orientation, an outer peripheral recess on each of the dials aligns with a corresponding dial engaging portion of the latch, allowing the latch to slide along the first axis from the door latching position to the door releasing position.

A laminated padlock comprises a laminated padlock body formed by laminating a plurality of lock sheets, a lock core assembly, and a lock beam connected with the top of the laminated padlock body. The lock core assembly comprises a first lock tongue, a second lock tongue, a large frame, a small frame, a lock core shaft and cipher wheels; the large frame is provided with a positioning resilient piece, and the lower end of the large frame is provided with a limiting plate with a limiting chuck; shaft holes; the small frame is provided with a small resilient piece, and a branch plate is arranged below. The laminated padlock achieves dual guarantee, perfectly solves the defect that the ciphers can be changed by a cipher adjusting rod under the condition of not knowing the ciphers when the lock beam is opened and greatly enhances the safety performance of the laminated padlock.

A holder for a portable lock, which has a lock body having a locking mechanism and a spring-loaded button, has at least a first holding section and a second holding section that is disposed opposite the first holding section with respect to a reception space for the lock body, wherein the first and second holding sections are configured to engage around the lock body, when inserted into the holder along an introduction direction, at a first side and at a second side of the lock body that is disposed opposite the first side. The holder has, at least at the first holding section, a securing opening that is formed to take the button of the lock body into engagement in order hereby to secure the lock body against an unintentional release from the holder against the introduction direction.

A chain lock includes a lock body having a first closure part, a second closure part, and a combination locking mechanism that is aligned along a lock axis. The chain lock having a bolt selectively locked to the lock body by the combination locking mechanism. The lock body has a chain connection part permanently connected to the bolt via a chain. The combination locking mechanism having a plurality of rotatable code setting rings arranged between the first and second closure parts. At a first end the lock body has at least one first fastening pin that engages through the housing sleeve into an annular groove of the chain connection part. At a second end the lock body has at least one second fastening pin that engages through the housing sleeve into the second closure part of the lock body and that fixes the second closure part to the housing sleeve.

A padlock comprising a body/housing which contains a fin-catcher and a plate-hole to receive the coupling-plate, a shackle which contains a short-leg and long-leg, so that the short-leg can move away from the locking-hole to control the locking and opening position, a plurality of clutches to prevent the lock from being opened when the dials are not in a lock open by combination code, and a plurality of dials to control the rotational movement of the clutches.

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.
