  • Patent number: 3949521
    Abstract: There is disclosed a walking toy figure such as a walking doll. The toy figure comprises a hollow trunk on which are suspended a pair of limbs such as legs which are freely pivotal between a standing position in which the legs occupy a substantially vertical position and a step position in which the legs are swung forwardly with reference to the standing position thereof. Drive means such as a miniature electric motor are coupled with the trunk so as to impart to the same lateral pendular movements. As a result of such movements, the weight of the figure is alternately shifted from one leg to the other, thereby causing the legs to swing alternately from the standing position to the step position and back again as the legs are lifted and put down again, thus causing the figure to walk forwardly in a wobbling manner similar to the walking of a toddler.
