A lock assembly includes a lock body and a U-shaped shackle having a curved portion extending between first and second legs receivable in first and second shackle apertures in an upper portion of the lockbox body. The shackle has a guard wall affixed to an interior surface of the curved portion, the guard wall defining an interior arcuate wall surface extending forward and rearward from a central plane bisecting the shackle. The upper portion of the lock body includes first and second protruding projections at least partially surrounding the first and second shackle apertures and defining first and second upwardly diverging interior surfaces laterally aligned with the curved portion of the shackle. The lock body includes a latching mechanism configured to secure the shackle in a plurality of latched positions to adjust a distance between the first and second upwardly diverging interior surfaces and the curved portion of the shackle. When the shackle is secured around a door handle with the shackle secured in a suitable one of the plurality of latched positions, abutment of the interior arcuate wall surface with a neck portion of the door handle impedes forward and rearward rotation of the lock assembly about a horizontal axis extending through the curved portion of the shackle and abutment of the first and second upwardly diverging interior surfaces with a neck portion of the door handle impedes side-to-side twisting rotation of the lock assembly about a vertical axis extending through the curved portion of the shackle.

Disclosed is a combination lock comprising: a lock body, a shackle, a combination assembly and a plurality of outer coverings, the combination assembly including a central slider and a plurality of combination disks, the plurality of combination disks being rotatable about and coaxially arranged on the central slider to determine whether the central slider is allowed to be moved to an unlocking position from a locking position such that locking or unlocking of the central slider is controlled according to a rotation position of the combination disks, the plurality of outer coverings being detachably mounted on external surfaces of the plurality of combination disks respectively, an outer surface of each outer covering being covered with an indicating marker, wherein the outer coverings are configured to be able to be detached from the external surfaces of the combination disks and be replaced by any other kinds of outer coverings having different indicating markers.

A portable lock apparatus is adaptable to readily transform between a single cable loop configuration or a double cable loop configuration, and incorporates a locking mechanism permitting selective release and securement of one or more cable ends to achieve either configuration. The lock apparatus may secure multiple components, particularly, when in the double cable loop configuration, thereby removing the need for multiple locks for securing a single article.

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 combination locking mechanism, particularly a strap lock that is secured via a rotary combination dial mechanism, is disclosed. The lock mechanism includes a clasp and a clasp receiver, and when locked, the clasp engages the clasp receiver creating a loop. The clasp receiver includes two sections, a body, and a latch member, both contained within a housing and creates a shear line between them. When the combination lock is in a locked condition at least two pins straddle the shear line and when in an unlocked condition the pins do not straddle the shear line. Contained within the body is the combination dial that includes a digit wheel and a pin receiver. After the user rotates the digit wheel to set a code for the unlocked condition, any other digit combination will put the lock in a locked condition.

A lock has a cable engageable with a lock body. The cable has two ends, each of which has a cable neck. The lock has a shaft operatively engaged with a stack of clutches and a plurality of dials. The shaft has a top portion with a shaft slot engageable with the cable neck on the first cable end. The first cable end can be released from the lock body with a combination mechanism. The lock has a fixed cam having a cam slot engageable with the cable neck of the second cable end. The lock further comprises a blocking plate slideably engaged with the fixed cam, and a rotatable cam configured to control the positions of the blocking plate. The rotatable cam is connected to a cylinder operable with a key to rotate the rotatable cam to release the second cable end from the fixed cam slot.

The present disclosure describes a combination-locking device comprising a locking body, a locking mechanism, and plurality of perceptibly identifiable entertainment media character picture representations substantially disposed on a portion of a plurality of human-interactive rotatable wheels. The plurality of perceptibly identifiable entertainment media character picture representations is operable to be arranged by a user in an at least one unique combination or sequence in order to facilitate the detachment of the locking mechanism from the locking body in an at least one location. The unique sequence or combination of perceptibly identifiable entertainment media character picture representations operable to facilitate separation of the locking mechanism from the locking body in the at least one location may be user-inputted via rotation of the plurality of rotatable wheels, or user-inputted via an electronics device comprising a suitable user-interfacing means substantially coupled to the combination locking device.

A lock is provided, the lock having: a lock mechanism having a first member and a second member, the first member and the second member each being slidably mounted to a housing of the combination lock, wherein the first member is capable of movement between a first position and a second position and the second member is capable of movement between a first position and a second position and wherein movement of the first member from the first position to the second position causes the second member to move from the first position to the second position; a bolt configured for movement between a locking position and an unlocking position, the bolt preventing the second member from moving from the second position to the first position when the bolt is in the locking position.

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.

An opening and closing device is provided. The opening and closing device includes a housing, a displacement restricting part, an electrical driving module, and an electroless driving module. The displacement restricting part is capable of moving with respect to the housing when the electrical driving module is in an unlocked state. The electrical driving module is capable of restricting the displacement restricting part from moving with respect to the housing when the electrical driving module is in a locked state. The electroless driving module is capable of releasing the electrical driving module's restriction over the moving of the displacement restricting part with respect to the housing via the hand-driven part.
