US 12,460,448 B2 · Electronic mortise lock cylinder

Abstract

A lock and method for locking including an electronic cylinder assembly that may be a direct replacement for a standard cylinder in a standard mortise type door lock housing. The cylinder assembly may include a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft. A clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The cylinder assembly also includes a slider with a finger, where the finger is engaged with the clutch, and a motor is configured to shift the slider axially between a first position and a second position. In the first position, the clutch is disengaged from the second shaft, and in the second position, the clutch is engaged with the second shaft, such that rotation of the first shaft causes rotation of the second shaft.
