A latch has a displaceable latching element in a housing for engagement with a separate striker arm to be latched behind an engagement shoulder of the latching element. The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key rotation the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm. Embodiments include a gravity biased and manually opened latch and a spring biased self-locking embodiment.

A method for profiling the broad sides of a flat key, a key blank being clamped in a clamping device so that the broad side of the key blank is exposed. Guide grooves and variation grooves which are complementary to the longitudinal sectional profile of the cutter teeth are milled into the broad side by advance in the longitudinal direction of the key, in one work operation, using a milling cutter that has cutter teeth on its peripheral surface and rotates about a cutter shaft. To produce undercut grooves, the axis of the cutter shaft is inclined at an angle of inclination relative to the longitudinal center plane of the key, ribs of the cutter teeth producing an undercut guide wall using at least one rib.

A key and a lock cylinder, which are formed such that the guiding the key into the keyhole and the key canal occurs precisely and in a user-friendly manner. The precise placement of the key in relation to the lock cylinder and its parts enables even distribution of the forces directed onto the key and the lock cylinder.

A lock assembly has a body, a latching device, a linking device and a locking mechanism. The linking device is connected to and driven by the latching device. The locking mechanism is moveably mounted in the body and has a bolt base, a pushing element, a lever element and a locking bolt. The bolt base is mounted slidably in the body. The locking bolt is slidably mounted on the bolt base and is driven to retract into or completely extends out from the body with the transmission of the pushing element and the lever element.

The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key causes rotation of the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm.

The invention relates to a disc tumbler cylinder lock and a key for it. The key according to the invention comprises a groove that is transverse to the key shank. The groove comprises a bottom section and side sections that are transverse to the bottom section between the bottom section and the outer surface of the key shank. The bottom section of the groove is the key's main driving surface used to transfer turning force to the disc tumbler cylinder lock. This reduces wear on the O-surfaces of the key because the O-surfaces do not transfer the majority or any of the key turning force to the disc tumbler cylinder lock.

A master key lock includes a lock cylinder having a keyway for receiving a key, a sleeve about the cylinder, a plurality of wafer tumblers, a master key and a spring operable to axially move the sleeve relative to the cylinder when the master key is inserted into the keyway. A system that uses the master key lock includes a lock case wherein the sleeve is disposed between the cylinder and the lock case, the sleeve being axially movable within the case. The sleeve comprises a plurality of transversely disposed slots for engaging the plurality of wafer tumblers such that the lock is unlocked by insertion of a key or a master key. A method of using the master key lock is also disclosed.

A rekeyable lock cylinder comprises a cylinder body and a plug assembly disposed within the cylinder body. The plug assembly comprises a plug body, a plurality of assembled pins, a position block and a rotating member. The plug body has a longitudinal axis, a transverse axis perpendicular to the longitudinal axis and a first through hole. Each of the assembled pins is movably disposed in the plug body and comprises a first rack component and a second rack component selectively engaging with the first rack component. The position block is disposed at the plug body and has a plurality of pin runners for disposing the first rack components and a second through hole corresponding to the first through hole. The rotating member is installed penetrating the first through hole and the second through hole and has a contacting portion located within the second through hole, wherein the position block is capable of being pushed by the contacting portion and moved along the transverse axis-direction of the plug body for disengaging the first rack components from the second rack components.
