The present invention discloses a lock that does not distinguish between public and private spaces and relates to the field of locks, comprising two sub locking systems which have the same structure, wherein the two sub locking systems are arranged mirror symmetrically on two sides. It can be optionally installed on both spaces where privacy is needed and a change of the entire lock is not required, such that all designs of an indoor layout and different requirements for design logics regarding doors are adjusted to, that a locking on both sides in an electrically controlled manner is possible, that rotation of a cylinder on both sides is prevented, and that an unlaching movement on both sides in an electrically controlled manner is possible.

A selectively lockable box may have a locking structure that may have a first bar, a second bar and a lock housing. The first and second bar engage with one another, and the lock, to lock the box. The first bar may be horizontally oriented to lock a box lid, and the second bar may be a vertically oriented to lock other access areas of the box.

A multipoint lock is described. The multipoint lock includes a main latch. The main latch has a latched position where the main latch is configured to extend a first distance from an unhinged edge of a door panel. The main latch is configured to be retractable toward the unhinged edge of the door panel by rotation of a latch drive hub in each of a clockwise direction and a counterclockwise direction relative to a first side of the door panel. The multipoint lock also includes at least one auxiliary latch and a deadbolt drive hub. Rotation of the deadbolt drive hub substantially simultaneously actuates the main latch and the at least one auxiliary latch.

A deadbolt lock includes a positioning member mounted to a lock part. A protective member includes a recess formed in one side thereof and is mounted to the lock part and the positioning member. A covered area is formed between the positioning member and the protective member. At least one fixing member is connected to the positioning member and located within the covered area. An outer cover is mounted to the protective member and the positioning member. The at least one fixing member is compact in size to reinforce the protective member to reduce manufacturing cost. The protective member and the outer cover are not damaged by impact from outside of the deadbolt lock to enhance safety features of the deadbolt lock.

The present disclosure relates to a lock for a double pane door. A lock body includes a cylinder and a bolt. A main body has front and rear faces, a bore receiving the cylinder of the lock body mounted on the rear face so that a key can be inserted in the cylinder from a front of the main body, and a pair of extensions projecting from the rear face of the main body. A bracket is mountable to a rail of the door frame at a junction between panes of the double pane door. The bracket forms a pair of recesses receiving the pair of extensions between the bracket and the rail when the main body is positioned for locking the doors. The bracket also has an opening for receiving the bolt when the bolt is placed in a locked position by action of the cylinder.

A lock with an emergency unlocking feature includes a latch bolt, a top rotation member, a restriction plate and a driving member. The driving member is connected to the deadbolt. When the top rotation member is rotated from a close position to an open position while the lock is locked, a restriction member drives the restriction plate to press a resilient unit. The restriction plate is moved to disengage the engaging member on the restriction plate from the second notch of the driving member. The guide slot of the transmission plate pulls the second guide member to move the deadbolt to the unlocked position, and the latch bolt moves to the open position. When in an emergency situation, the user rotates the handle to retract both of the deadbolt and the latch bolt without using a key to unlock the deadbolt to save time.

A selectively lockable box and a method of using the box are described. The locking structure for the box may have a first bar, a second bar and a lock housing. The first and second bar engage with one another, and the lock, to lock the box. The first bar may be horizontally oriented to lock a box lid, and the second bar may be a vertically oriented to lock other access areas of the box.

A bezel lock system includes a bezel, convert bracket (CB), and lock. The bezel attaches to a chassis panel. The CB slideably secures a latching bracket (LB) of the bezel to a chassis, when in a locked position. The CB slides a length of a release gap along a transverse path from the locked position to a released position. The lock restricts removal of the bezel from the chassis when the lock is engaged in a locked orientation (LO). The lock includes a cam bracket (CamB) that rotates between locked and unlocked orientations. In the LO, the CamB constrains the CB from moving inward on the path by abutting the CB; CB is confined between the LB and CamB. In the unlocked orientation, the CamB is disposed out of the CB's path, allowing the CB to retract inward to the release position, which allows the bezel to detach from the panel.
