This invention concerns a security lock for use with a lock unit. The security lock has a base, a casing in which the base is, in use, received, an elongate locking bolt, biasing means for urging the locking bolt towards its inoperative position, an externally accessible operating member for moving the locking bolt and a locking mechanism which is used to lock the bolt in its operative position. A securing mechanism is operable between a locked state in which the base and casing are locked to each other and a released state in which the base and casing are released from each other. A securing element is held captive such that it remains in position irrespective of whether the securing mechanism is in its locked or released state.

An enclosure for improving padlock security is provided. The enclosure includes a sleeve component that has openings at the left and right for receiving the padlock, cutouts at the top to access the shackle holes and a key slot at the bottom for accessing the padlock. The sleeve component containing the padlock is inserted into a tubular component. The tubular component has an opening at the bottom for receiving the sleeve component and padlock, one or more stoppers, capable of contacting the body of the padlock preventing further insertion of the padlock, while allowing the shackle to continue past, cutouts on the front and back sides of the enclosure beginning at the stoppers and proceeding upward and an opening at the top for accessing the shackle.

The invention relates to a transportable device for preventing a loss of a movable object, comprising a protective housing (2) for protecting the device (1), an electronic alarm device (35), which is arranged in the protective housing (2) and has an anti-theft alarm function, and fastening means (11) for detachably fastening the device (1) to the movable object, wherein the fastening means (11) comprise at least one wrap-around element (12; 46; 52; 59; 68) for wrapping around at least one part of the movable object and wherein the wrap-around elements (12; 46; 52; 59; 68) can be fixed by means of locking elements (19, 20, 21; 49, 50, 51; 55, 57, 58; 61, 63, 64, 65; 71, 72, 73), which are arranged in the protective housing (2), wherein the locking elements (19, 20, 21; 49, 50, 51; 55, 57, 58; 61, 63, 64, 65; 71, 72, 73) can be selectively opened and closed by means of a lock device (13) rigidly connected to the protective housing (2), and wherein additionally the protective housing (2) can be selectively opened and rigidly connected to the protective housing (2), and wherein additionally the protective housing (2) can be selectively opened and closed by means of said lock device (13) and access to at least one chamber (18, 33) in the protective housing (2) is thereby enabled.

An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

A lock assembly for an overhead door includes a lock bar and a spring clip receiver. The lock bar is configured to mount on and travel with the overhead door, and includes a track cover portion configured to encircle an overhead door guide track. The lock bar further includes a latch portion extending from the track cover portion. The spring clip receiver includes a spring clip configured to receive the latch portion of the lock bar, and a lock receiver having a pass-through hole for a lock shackle so that, when the overhead door is in a closed position, the lock shackle captures both the lock bar and the spring clip receiver to immobilize the overhead door. The lock assembly may further include an alignment bracket coupled to the lock bar defining an aperture configured to align with the pass-through hole in the lock receiver when the overhead door is in a closed position.

A lock for securing a toolbox to a support structure, the lock comprising: a first lock portion configured to receive a first part of the toolbox or a first attachment of the toolbox; and a second lock portion configured to engage a second part of the toolbox or a second attachment of the toolbox, the second lock portion being lockable to inhibit or substantially prevent disengagement of the second part or second attachment, wherein: the second lock portion is remote from the first lock portion, the first and second lock portions are securable with respect to a support structure, and the first lock portion is configured to guide movement of the second part of the toolbox or the second attachment of the toolbox into engagement with the second lock portion.

A system of isolation management comprises a computer for generating an isolation plan; a lockbox configured to receive the isolation plan from the computer; a mobile device associated with an individual, and one or more locks for isolation locking of an asset by each individual according to the isolation plan. The mobile device is allocated to the lockbox according to the isolation plan. The lockbox is configured to recognise the mobile device when proximal to the lockbox. The one or more isolation locks are removably housed in the lockbox. The one or more isolation locks are each able to be recognised by the mobile device and the mobile device is configured to record an association of one or more of the isolation locks to the mobile device according to the isolation plan. There is also an isolation point for isolating the asset with the one or more isolation locks according to the isolation plan. The isolation point is able to be recognised by the mobile device.

A holder, for a two-wheeler lock, includes a carrier that bounds a reception region for receiving the two-wheeler lock and a fixing element supported at the carrier and movable between an open position and a closed position for fixing the two-wheeler lock in the reception region. A support element is provided at the carrier that projects from the carrier along a transverse axis aligned transversely to the longitudinal axis of the carrier and is configured to engage into a cut-out of the two-wheeler lock. The support element is the only element of the holder that supports the two-wheeler lock received in the reception region against a movement along the longitudinal axis of the carrier in the open position of the fixing element, with the fixing element blocks the two-wheeler lock against a removal from the support element along the transverse axis in the closed position.

A locking device for securing and handling objects is disclosed. The locking device includes a cable having a first end and a second end, wherein the cable includes a flexible metal wire extending throughout a length thereof and an outer protective cover enclosing the flexible metal wire therein. The locking device also includes a male connector arranged at the first end of the cable. The locking device further includes a locking member arranged at the second end of the cable, wherein the locking member includes a female connector with a radial through hole so as to mateably receive at least a portion of the male connector therein to engage therewith, and wherein the locking member is configured to lock the male connector in the female connector when engaged therewith so as to form a closed loop of the cable.
