An illustrative motor drive assembly is configured for use in a lockset comprising a case, a longitudinally movable link, and a catch configured to move among a locking position and an unlocking position in response to longitudinal movement of the link. The illustrative motor drive assembly includes a longitudinally extending shaft comprising a worm, a motor operable to rotate the shaft, a driver engaged with the worm, and a longitudinally extending spring. The spring is not directly engaged with the worm, and includes a first end coupled with the driver and a second end connectable with the link. Engagement between the worm and driver is configured to longitudinally move the driver in response to rotation of the shaft.

Lock drive assemblies

An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.

Modular cylindrical lockset

An apparatus and method is disclosed for electronic locks with a selectable power off function. The electronic lock includes an electronic controller disposed within a lock housing and operable to control a state of the lock between locked and unlocked positions. An electronic actuator electrically coupled to the controller is movable between first and second positions corresponding to a locked position and an unlocked position of the lock, respectively. The electronic lock further includes at least one electrical energy storage device and a selector switch coupled to the controller to define a desired state of the lock between one of an electrically locked (EL) and an electrically unlocked (EU) state in an electric power off condition.

Electronic lock with selectable power off function

A locking assembly including first and second hubs rotatably mounted in a case, a latch assembly which retracts in response to rotation of either of the hubs, and a locking member which selectively prevents rotation of at least one of the hubs. A sensor assembly is associated with at least one of the hubs, and is configured to transmit a signal in response to rotation of the at least one hub.
