A walking mechanism for a toy doll or character (10) having at least one pair of legs (20,21). Each leg has a hip end (22,23) and a foot end (24,25). A pair of elliptical idler gears (90,91) are mounted for rotation about a common shaft (60), 180 degrees out of-phase. A second pair of elliptical gears (92,93), each in driving relationship with a respective one of the elliptical idler gears (90,91) are also 180 degrees out-of-phase. The hip end (22,23) of each leg is mounted for movement with a stub shaft (118,119) that is in a driven relationship with a respective one of the 180 degrees out-of-phase elliptical driving gears (92,93) to produce a varying speed, generally elliptical orbital movement of the legs to simulate walking.

Mécanisme marcheur pour jouet ou personnage (10) comprenant au moins une paire de jambes (20, 21). Chaque jambe comporte une extrémité hanche (22, 23) et une extrémité pied (24, 25). Une paire d'engrenages baladeurs elliptiques (90, 91) sont montés de façon à tourner autour d'un arbre commun (60) avec un décalage de 180 DEG . Une seconde paire d'engrenages elliptiques (92, 93), dont chacun est entraîné par l'engrenage baladeur correspondant (90, 91), sont également décalés de 180 DEG . L'extrémité hanche (22, 23) de chaque jambe est montée, de façon à effectuer des mouvements, sur un arbre de liaison (118, 119) entraîné par l'engrenage d'entraînement elliptique décalé de 180 DEG correspondant, de façon à produire au niveau des jambes un mouvement orbital généralement elliptique, de vitesse variable, qui simule la marche.
