A door includes a rectangular panel having a first face, a second face, and two pairs of opposing edges, in which the edges of each pair of edges are parallel and in which a first pair of edges is longer than a second pair of edges. The rectangular panel includes a layered composite material, in which a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer and that includes a material having a negative Poisson's ratio (NPR). The door includes a hinge including plates joined together by a joint, in which a first one of the plates is attached to a first one of the edges of the first pair of edges and in which a second one of the plates extends beyond the first one of the edges. The door also includes a handle opening defined through a thickness of the rectangular panel.

A rack security system includes a locking mechanism connected to a server. The locking mechanism is configured to lock onto the busbar of a rack. When the locking mechanism is locked to the busbar, the locking mechanism may prevent removal of the server from the rack. When the locking mechanism is unlocked, the server may be removable from the rack.

A conventional safe proper becomes useless when unable to be locked or unlocked, thereby causing a waste of resources. Locks capable of being locked/unlocked are provided to unfasten a common fastening member, so as to open a door or lid from the body, allow each lock to be freely mounted on and dismounted from a lock mounting portion, and dispose a false lock on each lock. An operating means of locking/unlocking any one of the locks is provided to enable persistent use of a common latch disposed at an identity opening of a safe proper.

A security system having a device that attach directly to and locks on or around an object to be secured, or one or more parts of the system are integrated into a full or partial enclosure that fully or partially encloses or surrounds the object to be secured, that cannot be removed from the object or enclosure without disengaging the locking mechanism through a provided method, and when the device is attached to the object or integrated into the enclosure, the system renders the object unusable for its intended use, and the system is capable of determining location, has a radio transmitter and/or transceiver capable of processing, transmitting and/or relaying information, data and images over terrestrial and/or satellite communication networks, and can include various sensors and other data and image gathering methods, and can contain an audible alarm.

A window latch for a sliding window having a sliding sash including a latch plate and a housing. The housing includes an engagement element movable relative to the housing from a locked position operatively engaged with the latch plate to an unlocked position disengaged from the latch plate. A handle is operatively coupled to the engagement element and movable from a first position to a second position in a first direction corresponding to the direction the sliding sash to which the handle is attached moves to an open position. The handle operatively moves the engagement element from the locked position to the unlocked position as the handle is moved in the first direction toward the second position.

A dial ring assembly for an electromechanical combination lock includes a housing configured to be mounted on an exterior of a securable enclosure, a dial rotatably disposed on the housing, the dial being rotatable about a dial axis for use in connection with entry of a combination, a lever rotatably disposed on the housing, the lever being rotatable about a lever axis, an external generator disposed in the housing, the external generator being configured to generate electrical energy through rotation of an external generator shaft of the external generator, and a gear train disposed in the housing and operatively connecting the dial, the lever, and the external generator shaft such that rotation of the dial rotates the external generator shaft to produce electrical energy and rotation of the lever rotates the external generator shaft to produce electrical energy.

The anti-theft device is configured in a door lock, and contains a first blocking piece, a second blocking device, a positioning piece, and a lever. The first blocking piece contains a first section and a second section bended and extended perpendicularly from the first section. The first section has a first through hole and a second through hole. The lever is engaged by a lock heart of the door lock. When the door lock is locked, the lock heart is turned to engage the lever so that the lever drives the first blocking piece downward by its first through hole. The second section of the first blocking piece as such blocks a lock tongue of the door lock so that the door lock cannot be opened without using key.
