ABSTRACT:
A rocking mechanism for providing an interesting, apparently random motion for a toy or game using an electric motor with very low battery drain, wherein an unbalancing weight is mounted on a driven wheel driven by a small PM motor, the wheel carrying a cam which controls the action of a first switch connecting the motor to a battery with a second horizontal sensing switch connected in parallel with the first switch, all mounted in a frame which allows it to rock three-dimensionally. In a modified form of rocking mechanism for providing apparently random motion using a spring-loaded motor, an unbalancing weight is mounted on a driven wheel driven by a spring motor linked by a gear train to an oscillating escapement and pin actuator for controlling the unwinding of the motor spring, all mounted in a frame which allows it to rock three-dimensionally.
