FOUR-LEGGED WALKING TOY WITH IMPROVED LEG ACTION

摘要

A four-legged walking toy includes a body supported by four pivotally secured legs and a drive mechanism operative upon the legs which includes a pair of mirror image drive units each having three elliptical gears therein. The center elliptical gears of each drive unit are coupled in a one hundred eighty degree phase relationship to offset the operation of left legs from right legs correspondingly. A plurality of frictional members are positioned on the underside of the animal hooves to provide frictional engagement as the walking toy is pushed across a suitable surface. The rearward movement of each forwardly extended leg couples rotational power through the elliptical gear mechanisms to the remaining legs to provide a realistic motion profile.
