Abstract
A walking mechanism for a toy doll or character having at least one pair of legs. Each leg has a hip end and a foot end. A pair of elliptical idler gears are mounted for rotation about a common shaft, 180 degrees out-of-phase. A second pair of elliptical gears, each in driving relationship with a respective one of the elliptical idler gears are also 180 degrees out-of-phase. The hip end of each leg is mounted for movement with a stub shaft that is in a driven relationship with a respective one of the 180 degree out-of-phase elliptical driving gears to produce a varying speed, generally elliptical orbital movement of the legs to simulate walking.
Claims16
A walking mechanism for a toy comprising in combination:
- a torso;
- a pair of spaced apart mounting plates carried by the torso;
- a pair of legs with each leg having a hip end and a foot end;
- a common shaft carried between the mounting plates;
- a pair of elliptical idler gears mounted on the common shaft for rotation;
- the elliptical idler gears being out-of-phase with respect to each other;
- a pair of elliptical driving gears, each in driving relationship with a respective one of the elliptical idler gears;
- the elliptical driving gears being mounted for out-of-phase rotation with respect to each other;
- a pair of stub shafts, each stub shaft mounted for movement with respect to a respective mounting plate;
- and
- the hip end of each leg mounted for movement with a stub shaft that is in driven relationship with a respective one of the out-of-phase elliptical driving gears to produce a varying speed, generally elliptical orbital movement of the legs to simulate walking.
