<p>The mechanism comprises an electric motor 12 capable of rotating in two directions and transmitting rotational movement through an endless belt 14 and two reducer trains 15, 16 to a clutch assembly 17 comprising a center drive wheel 18 and two driven wheels or pinions 19, 20, one on each side, which rotate in a mutually excluding manner depending on the rotational direction of drive wheel 18, its facing side surfaces presenting saw teeth 21, 22 of an appropriate configuration. When the mechanism is activated by removing the pacifier 5 from the doll's mouth, a first phase is executed, consisting in an unsteady walking motion generated by eccentric discs 25 and connecting rods 26, 27; after a specified time has elapsed, this passes on to a second phase consisting in a fall and subsequent upright recovery of the doll, driven by a central wheel 32. <IMAGE></p> |
