ABSTRACT:
A lock assembly comprising a casing, a lever rotatably attached to the casing, the lever having a spindle attached thereto, a motor secured to the casing, the motor having a shaft, a substantially cylindrical member attached to the motor shaft and having a helically extending groove, and an interfering member threadedly and non-rotatably engaged with the helically extending groove of the cylindrical member. The interfering member moves between a locked position and an unlocked position. The interfering member moves into the locked position to prevent rotation of the lever when the motor shaft rotates in one direction. The interfering member moves into the unlocked position to allow rotation of the lever when the motor shaft rotates in an opposite direction.
