<p>A four-legged walking toy (10) includes a body (11) supported by four pivotally secured legs (20-23) and a drive mechanism (30) operative upon the legs (20-23) which includes a pair of mirror image drive units each having three elliptical gears (80-82) therein. The center elliptical gears (81, 90) 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 (24-27) are positioned on the underside of the animal hooves to provide frictional engagement as the walking toy is driven across a suitable surface. The rearward movement of each forwardly extending leg couples rotational power through the elliptical gear (80-82, 90) mechanisms to the remaining legs to provide a realistic motion profile.</p> |
