Abstract
In accordance with the present invention, the preferred embodiment of a movable gear drive windshield wiper apparatus employs an axial motion mechanism and a bidirectional driving mechanism. Rotation of a rotatable member in a first direction causes a transverse movement of the rotatable member along a ball screw shaft of the axial motion mechanism to a first position where it rotates in a given plane. Rotation of the rotatable member in the opposite direction causes the rotatable member to move down the ball screw shaft to a second position where it rotates in a second given plane. In another aspect of the present invention, the bi-directional driving mechanism rotationally drives a driven member such that the driven member is oscillated by continuously rotating the rotatable member in the first direction. In a further aspect of the present invention, the rotatable member selectively actuates a plurality of discrete motion mechanisms thereby causing a plurality of mechanical devices coupled thereto to operate.
