  • Patent number: 4695266
    Abstract: A steerable electric toy car includes a steering mechanism including a weight body with an electrically conductive activating finger and a weight at two ends thereof, suspended on a grip member. Two pairs of contacts are fixed on the grip member in a position that the activating finger does not abut them when the grip member is held upright, but that the activating finger does abut them when the grip member is rotated and the weight maintains the original position of the weight body relative to the ground. The toy car further includes a gearing for turning the wheels of the car which has a frictional arrangement for preventing damage to the powering motor when the wheels can be turned no further.
