Abstract: A door lock that includes a clutch mechanically arranged between a drive motor and a lock drive with the clutch having a clutch gear that is movable between engaged and disengaged positions to selectively couple and uncouple the drive motor from the lock drive from the drive motor. The clutch gear may be movable along a pathway between engaged and disengaged positions, e.g., in a direction perpendicular to a rotation axis of the clutch gear. The clutch gear may selectively couple and uncouple the drive motor from the lock drive based on movement of the drive motor.

Abstract: A door lock includes a motor and thumb turn that can be selectively used to move a lock drive and lock mechanism between lock and unlock positions. A position sensor can detect a position of the lock drive independent of movement of any drive train component operating to move the lock drive, such as a motor, transmission or other drive train element. The position sensor may be coupled to a position gear that moves in response to lock drive movement, but is independent of any drive train component, i.e., the position gear does not transmit drive energy to the lock drive. A clutch may be provided that decouples the drive train from the lock drive.
