MOTORIZED LOCK DEVICE
The invention relates to a motorised lock device (200) having a rotatable lock shaft (120) which can be connected to a door lock cylinder comprising a lock bolt. The device comprises a coupling bush (230) mounted around the lock shaft (120) and a gear wheel (240) mounted around the coupling bush, which engages therewith. The coupling bush is axially displaceable between a disengaged position and an engaged position in which the bush is rotationally coupled to the lock shaft, to enable motorised operation of the lock bolt. Axial displacement is effected by driven rotation of the gear wheel (140), via cooperation between at least one first cam provided on the coupling bush and at least at least one second cam (245), whereby at least one of the first and second cams comprises a ramp surface (235) inclined in axial direction. The lock device is further provided with anti-rotation means for preventing rotation of bush when in the disengaged position and with a return mechanism (250) for returning the bush to the disengaged position.
