摘要： A rekeyable lock cylinder with a cylinder body and a plug assembly. The lock cylinder includes a plurality of key followers and a corresponding plurality of racks disposed in the plug assembly. The lock cylinder includes, for example, a locking bar for blocking rotation of the plug assembly with respect to the cylinder body to prevent unlocking of the rekeyable lock cylinder with an unauthorized object. In some embodiments, the locking bar is configured such that torqueing the plug assembly with an unauthorized object applies force to the locking bar without translating such force to the plurality of racks. This type of arrangement enhances torque resistance of the lock cylinder against attempted forced entry.

摘要： An electronic lock includes a latch assembly that includes a bolt that is movable between an extended position and a retracted position. The electronic lock includes a keypad for receiving a keypad input event. The electronic lock includes a processing unit being configured to control the movement of the bolt between the extended position and the retracted position responsive to receiving a valid keypad input event. The processing unit is configured to capture the keypad input event. Based at least in part on a characteristic of the keypad input event, the processing unit indicates if a tampering event exists. The characteristic includes at least one of an input location on the keypad, an input duration on the keypad, and an input timestamp.

摘要： A door handle may be mounted to a door with concealed fasteners. The fasteners do not engage the door itself, but rather engage a top plate that is mounted to the door. The fasteners are inserted into a hidden portion of the door handle and generate an opposing force as they press against a bulging portion of the top plate to produce a force that retains the door handle in place. The force generated also urges the door handle into a bottom plate on an opposing side of the door handle. The bottom plate includes a first and second planar section. The second planar section of the bottom plate is received into a receiving slot of the door handle. As a result, the door handle is retained on the door without any visible fasteners.

摘要： An adapter for either a handle set or a lever set door lever is equipped with a pair of springs to provide a pre-load on the spindle. The pre-load prevents sagging of the lever due to the large mass of the lever. A sleeve in the adapter is formed out of a compressible material that accepts the spindle in a press-fit configuration. This allows for greater manufacturing tolerances while still providing a solid and secure engagement between the spindle and the adapter. As a result, any free play in the lever is eliminated and the lever is maintained in a horizontal, home position when the lever is not in use. Following use through rotation of the lever, the springs promptly return the lever back to the home position while the sleeve prevents any slop or free-play in the lever's motion.

摘要： An electronic lock may be used to monitor and control access throughout a home. The electronic lock is preferably mounted to a main enter/exit door on the home as this provides a good point of contact for users entering and leaving the home. The electronic lock may monitor users, appliances, safety, and operation of interior doors. Access may be controlled and/or monitored by users with a mobile device or through any other similar device.
