A method for consigning a function of an electrical device includes: a) receiving a request to consign a function implemented by a sub-assembly of the electrical device, the request being transmitted by a client terminal connected to the control unit via a short-range communication link; b) generating a digital key including a unique identifier; c) storing one copy of the generated key in a memory of the control unit and sending another copy of the generated key to the client terminal that transmitted the request; d) consigning the function so as to prevent this function of the device from being used by the control unit as long as the consignation is active.

A wrench for securing, actuating and preventing tampering with a fire hydrant is disclosed. In useful embodiments, the wrench can be a two-ended wrench having a loop that encloses a pentagonal opening at either end of an elongated handle, where the handle can include in a nonterminal portion a slot. In a locking mode, the wrench can accept at a first end an actuating nut of the fire hydrant and can be locked in place by inserting a locking arm of a padlock through an eye bolt that is secured to a side of the fire hydrant and inserted through the slot. The wrench can be unlocked and removed, whereupon a second end can be used to turn the actuating nut as well as to remove water outlet caps and adjust nozzles.

A locker (1) including a lockable compartment (3) and an anchor (5). At least a portion of the compartment is tapered to penetrate particulate. The anchor is below the compartment and rotatable to pull the compartment at least partly into the particulate.

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.

A lockable latch handle assembly for enclosures such as truck tool boxes comprises the combination of a key cylinder, and a latch handle that may be secured by a padlock to the front wall of the box, to collectively prevent opening of latches that secure the lid of the box in a closed position.

A theft deterrent system for an electronics cabinet includes a handle cover having through-holes dimensioned to align with a through-hole in a handle of the electronics cabinet. The through-holes of the handle cover may be dimensioned to receive a shackle of a lock. The theft deterrent system further includes a shackle cover dimensioned to receive the shackle of the lock. The shackle cover may include an upper tab and a lower tab, each comprising a respective shackle slot therein dimensioned to receive the shackle of the lock.

Improvements in a hasp are disclosed. The hasp allows for locking the hasp with a cylindrical lock to operate on a door such as, but not limited to, a garage door, a roll-up door or a shed door. This configuration allows for upgrade or replacement of these types of door locks without requiring re-design or replacement of the door. The cylindrical locks offer a greater protection because they can't be “picked” using traditional lock picking tools. This makes the lock safer from people that may try to break into the door. The cylindrical lock fits primarily within the hasp. This prevents a person from grinding through the lock or shackle. The shackle can be configured with just the circular opening for the key visible. It can be further enclosed to prevent infestation from bugs such as hornets that can fill the inside of the hasp with dirt.

A modular electrical safety assembly for use with a control device of an electrical equipment includes a magnet housing with a magnet, an equipment cover, and a slider. The magnet housing includes a magnet to selectively couple to the electrical equipment. The magnet induces an attraction force on the electrical equipment. The equipment cover is coupled to the magnet housing and configured to prevent operation of the control device. The slider is configured to translate along a surface of the equipment cover between a first position and a second position. In the first position it prevents a change in polarity of the magnet. In the second position it permits a change in polarity of the magnet. The slider and equipment cover lock together to selectively restrict translation of the slider.
