Novel climbing toy
摘要:
This invention is a climbing toy which features simple structure, life-like action and stronger attraction. Orbiting friction wheels hold clothing or other material, and the toy climbs up in the direction of moving of these wheels. A balancing is achieved with a lever which moves a convex pad on each of the hands and feet for climbing. A driving mechanism with an interior mercury switch controls the action of climbing depending upon the attitude with the aid of motion of the body.
