Abstract
A drive mechanism for a toy or the like for imparting reciprocal movement to a driven member. In one toy application, the driven member comprises a sidewalk, and the drive mechanism imparts reciprocal movement to the sidewalk in either direction of movement of the drive mechanism. By designing the drive mechanism so that the sidewalk is moved in a forward direction at a slow rate of speed and in a reverse direction at a high rate of speed, it is possible to make objects such as toy people or animals advance in steps along the sidewalk.
