Abstract
Abstract A dancing hula doll which alternatively moves its hips left and right to give it a lifelikeness that compares with a real hula dancer. The doll includes an upper portion, a lower portion, and a base portion. The upper portion resembles and head through waist of a human; the lower portion resembles the waist through hip portion of a human. The upper portion is pivotally connected to the lower portion by a hinge pin. An activator pin is connected to the inner surface of the lower portion. The base portion supports the upper portion and the lower portion by a support rod, one end of which is secured to the base portion and the other end of which is placed in a cavity within the head of the upper portion. The base portion includes a housing with a turning plate secured to its bottom portion, a stationary base with feet spaced below the turning plate, a switch, a battery, a motor, an I.C. Electronic Melody Circuit, a speaker, a drive gear, a cam, a lever arm, a pivot at the middle portion of the lever arm, and gearing which will transmit the motion of the motor to the cam and will cause the turning plate to rotate slowly. When the switch is turned on, the motor turns the cam that in turn activates the lever arm that in turn moves the activator pin that in turn alternately moves the hips of the doll left and right, while the doll slowly turns counterclockwise and a Hawaiian melody is heard.
