A remotely controllable lock includes a housing, a motor mounted in the housing, and a control device mounted in the housing for activating the motor. A gear train is mounted in the housing and driven by an output shaft of the motor and has a drive gear. A turn knob has an axle rod extended through an axle tube mounted to the housing. The axle rod is engaged with a driving member for driving a dead bolt of the door lock. When the turn knob is manually turned through a pre-determined angle, the movable plate is moved from a first position representing one of a locked status and an unlocked status of the dead bolt to a second position representing the other one of the locked status and the unlocked status without actuating the drive gear. When the control device receives a signal from remote control that request a change in the status of the dead bolt, the movable plate is moved by the drive gear from one of the first position and the second position to the other of the first position and the second position, and the turn knob is turned through the pre-determined angle.

[ What is claimed is:] [1.] A remotely controllable lock, comprising:a housing including an axle tube, the housing further including a switching means and a positioning switch mounted thereon,a motor mounted in the housing, said motor having an output shaft,a control means for activation by a remote controller, said control means is mounted in the housing for activating the motor,a gear train mounted in the housing and driven by the output shaft of the motor, said gear train having a driving gear, the driving gear including an eccentric rib and an arcuate rib provided thereon, in which when the driving gear is rotated through a pre-determined angle, the eccentric rib activates the positioning switch on the housing to cause the control means to send a signal to stop the motor,a turn knob having an axle rod rotatably extended through the axle tube of the housing, the axle rod being adapted to be engaged with a driving member for driving a dead bolt of the lock, the driving gear being freely, rotatably mounted around the axle rod, the turn knob further including a gear securely mounted thereon to rotate therewith, anda movable plate movably mounted in the housing, the movable plate including:a slot through which the axle rod of the turn knob is extended,an upper block and a lower block provided on an upper end and a lower end thereof, respectively, in which when the driving gear does not rotate, the arcuate rib on the driving gear disengaged from and thus does not interfere with the upper block and the lower block, andan activating rod which activates the switching means to send a signal when the movable plate moves to a pre-determined position in a direction,whereby when the turn knob is manually turned through a pre-determined angle, the movable plate is moved from a first position representing one of a locked status and an unlocked status of the dead bolt to a second position representing the other one of the locked status and the unlocked status without actuating the driving gear, andwhereby when the control means receives a signal from a remote controller that request a change in the status of the dead bolt, the movable plate is moved by the driving gear from one of the first position and the second position to the other of the first position and the second position, and the turn knob is turned through the pre-determined angle.
