A compression latch for a door includes a driver that is rotatable with respect to the door between an unlocked position and a locked position. The driver is configured to be mounted to one side of the door. A driver shaft is non-rotatably connected to the driver such that the driver shaft rotates along with the driver. In an unlocked position of the driver, the pawl is positioned to permit opening of the door, and, in a locked position of the driver, the pawl is positioned to prevent opening of the door. The compression latch is configured to translate the pawl closer toward the door upon rotating the driver from the unlocked position to the locked position.

A method for mutually controlling and unlocking a dual plug in a lock, comprising: unlocking a code of a first plug first, the first plug restricting unlocking of a second plug, the second plug restricting rotating of the first plug before the code of the first plug is unlocked; after unlocking the code of the first plug, the first plug translating to a second position from a first position using a preset position difference, the first plug being unable to rotate during the translation; after moving the first plug to the second position, the first plug releasing a restriction on the second plug, the second plug still restricting the rotating of the first plug; and unlocking the code of the second plug, the first plug and the second plug being able to rotate synchronously so as to unlock the lock after unlocking the code of the second plug. The present invention further relates to a lock with a dual plug.

A tubular lock assembly has a tubular lock, a cover, and a disassembling unit. The tubular lock has an annular keyhole and a cover screw hole enclosed by the keyhole. The cover is detachably assembled with the tubular lock, and has a covering board segment, a screw rod segment, and a first fitting segment. The covering board segment covers the keyhole. The screw rod segment is detachably screwed in the cover screw hole of the tubular lock. The first fitting segment is formed on the covering board segment. The disassembling unit has a second fitting segment. The second fitting segment corresponds in shape and size with the first fitting segment of the cover, such that the second fitting segment is adapted to engage with the first fitting segment, and the disassembling unit is capable of rotating the cover.

A latch is configured to fix a panel relative to a frame. The latch includes a housing having a longitudinal axis and defining an aperture along the longitudinal axis; a cap mounted within the aperture of the housing for rotation about the longitudinal axis, the cap comprising a drive surface; and a cover coupled to the housing to pivot about a lateral axis, the cover pivotable to be in a closed position in which the cover covers the cap; wherein when the cap is in an unlatched position, the drive surface of the cap is aligned with an engagement surface of the cover and positioned to block the cover from pivoting to the closed position; and wherein when the cap is in a latched position, the drive surface is unaligned with the engagement surface and positioned to permit the cover to pivot to the closed position.

This cylinder lock is a cylinder lock which can lock and unlock a mortise lock via a displacement transmission member. The cylinder lock comprises: a cylinder lock body; a key insertion part which is provided on one end side of the cylinder lock body and into which a key is inserted; and a displacement transmission member mounting part which is provided on the other end side of the cylinder lock body and on which the displacement transmission member can be mounted. A plurality of displacement transmission members corresponding to each of case locks having a plurality of specifications can be removably mounted on the displacement transmission member mounting part. Thus, cylinder locks having the same specification can be applied to case locks having a variety of specifications.

A weather resistant pin lock with an elongated body, defining a longitudinal axis includes a shell housing a rotatable core having a keyway. An elevated pinway projects upwardly from the shell to define a linear array of pin slots containing a set of lock pins. A hood is fastened to the pinway to hold the lock pins in the pin slots and to provide a water resistant barrier. A drainway provides a channel for water to flow outwardly from the interior of the shell, the rotatable core and the keyway within the core, to a drain below the pin lock. At the proximate end, an access door rotates adjacent the keyway at an elevated position, to provide a gap along the bottom edge of the access door.

The COMBINATION DEADBOLT LOCK COVER is a cover that goes over the deadbolt to keep lock-pickers from gaining access to the deadbolt lock of a dwelling. It consists of two components. The first component is the cover that you place the outside locking mechanism of your deadbolt inside and secure it to the hole on your dwelling door that the deadbolt originally goes. Once you screw your deadbolt lock with the COMBINATION DEADBOLT LOCK COVER securely covering your deadbolt lock then you slide the second part of the COMBINATION DEADBOLT LOCK COVER which is a DROPDOWN PLATE into a prefabricated slot to render the deadbolt lock of your dwelling completely un-accessible. The DROPDOWN PLATE has a hole in it in which you can slide a combination lock or a standard lock into making the deadbolt lock on your dwelling door un-seen and un-accessible.

Certain exemplary embodiments can provide a system, which can comprise a securement. The securement comprises a rising member and defining at least a first slot. The system can comprise a locking member, the locking member defining an aperture. Wherein, when operatively coupled to the securement, a padlock coupled to the locking member via the aperture prevents removal of the locking member from the securement.

A lock can include attack-resistant and/or weather-resistant features. Attack-resistant features can include a sacrificial link between a locking mechanism and an external keyway covering an exterior face of the locking mechanism. The sacrificial link can break during a torque attack on the lock such that the full force of the torque attack is not applied to the locking mechanism. Weather-resistant features can include drain openings in one or more housing components external to the locking mechanism to facilitate drainage of liquid matter from the lock before the liquid matter reaches the locking mechanism.
