  • Patent number: 5158492
    Abstract: An automotive doll that is activated by light. The doll has at least two moving parts, preferably the head, arms and torso of a girl like figure. Within the torso of the doll is a motor that is connected to a plurality of gears and cams that are attached to the moving parts. The motor is preferably powered by batteries that are connected to a light sensor attached to the doll. The sensor switches on the motor when light is directed toward the sensor. When the motor is activated, the torso, arms and head all move relative to each other. The parts move through predetermined cycles, such that the head, arms and torso rotate back and forth between two positions. The drive mechanism is constructed and arranged so that each moving part rotates through a different cycle. Such an arrangement creates a doll that can move into an almost infinite variety of positions, greatly reducing the mechanical appearance of the toy.
