Drive for toy with suction cup feet
First Claim
1. A device employed in motorized toys comprising:
- a motor-driven mechanism; and
a pair of mechanical limbs driven and governed by said motor-driven mechanism,wherein each mechanical limb comprises a resilient sucker movably seated at the bottom of the limb, and said motor-driven mechanism is operative to drive the said mechanical limbs along a defined path,wherein said motor-driven mechanism comprises a gearbox, operative to drive a pair of driving wheels seated on both sides of said gearbox, said device further comprising a gear-engaging shaft protruding from the gearbox for coupling said driving wheels, and a pair of geneva wheels coupled and driven by said driving wheels, andwherein each geneva wheel is provided with a plurality of slots in different transversal curvatures to achieve intermittent maneuver and variant velocity of revolving.

Abstract
An electrically-powered device incorporated in a toy comprising a motor-driven mechanism and a pair of robotic-limbs each with a resilient sucker to emulate human walking motion on vertical wall or on ceiling, providing the surface is virtually smooth and leveled. The motor and gear assembly is housed in the gearbox while a gear-engaged shaft adjoins a pair of driving wheels, which output the force to a pair of geneva wheels. The geneva wheels that are coupled with the limbs rotate in varied velocity as long as the driving studs of the driving wheel dwells. A lever is disposed in the limb and is actuated by the driven wheel to lift up the sucker that is located at the bottom of the limb, whenever the limb is designated to leave the surface. The pair of driving wheels are properly orientated while one of the geneva wheels is arranged at 180 degree out of phase to its counterpart to ensure either one of the limbs clinched firmly onto the surface.

10. A driving device for a toy comprising:
-
a pair of feet for moving a toy along a surface, each of said feet including a hollow limb, a suction cup movably received in said limb of said each feet for movement along a longitudinal axis between a receded position where said suction cup is within said limb and a lowered position where said suction cup projects outwardly from an lower end of said limb, and a spring for urging said suction cup toward said receded position; means for driving said feet along a defined locus to bring said suction cups alternately into attachment to a surface; and means for moving and retaining each of said suction cups to and at said lowered position during cup-attaching movement of a respective one of said feet and for releasing said each suction cup from said lowered position upon completion of said attachment. - View Dependent Claims (11, 12, 13, 14, 15)
