Abstract
An electrically operated drive device includes a wheel gear rotatably mounted on a spindle of a turning lever of a door lock. The wheel gear is driven by a motor, and has a cam member disposed thereon. A crank member has a crankshaft mounted on and rotatable with the spindle, and a crank pin. A shifting mechanism is disposed between the wheel gear and the crank member, and includes front and rear major walls that cooperate respectively with the crank member and the cam member to permit right and left displacement of the shifting member to thereby bring a deadbolt to one of retracted and extended positions.
