Abstract
Door lock control apparatus includes a rotary input part adapted to be rotated by a handle or knob; a rotary output part adapted to operate a lock mechanism; and structure coupling the input part to the output part, including a pinion gear coupled to the output part; a member having first and second lengthwise extending racks thereon and bodily shiftable between a first position in which the first rack engages the pinion, and a second position in which the second rack engages the pinion, that member also being bodily movable in the length direction of the racks; and a mechanism operatively coupled between the input part and the member to have that member in the length direction in response to rotation of the input part; the racks located to alternately engage the pinion in such first and second positions so that in the member's first position the output part is rotated clockwise when the input part is rotated clockwise, and in the member's second position the output part is rotated counterclockwise when the input part is rotated clockwise, or vice versa depending on 'handing'.
