Abstract
The problem of providing a simplified actuator apparatus (10) for converting unidirectional motion to multidirectional motion is provided by a driven member (14) rotatable about a first axis (18) and a drive member (12) rotatable about a second axis (28) generally parallel to and spaced from the first axis (18). The driven member (14) has first (20) and second (22) radially disposed, diametrically opposed cam followers. The drive member (12) has first (36) and second (38) radially disposed cam actuators. The first cam follower (20) of the driven member (14) is engageable by the first cam actuator (36) of the drive member (12) for driving the driven member in one direction of rotation in response to rotation of the drive member in one direction. The second cam follower (22) of the driven member (14) is engageable by the second cam actuator (38) of the drive member (12) for driving the driven member in an opposite direction of rotation in response to continued rotation of the drive member in the same, one direction.
