Abstract:
A gyroscopic toy comprising:a housing; a shaft coupled to the housing and extending in the housing, wherein the shaft can rotate relative to the housing; a flywheel coupled to the shaft wherein rotation of the shaft rotates the flywheel; a gear plate penetrated by the shaft; a drive gear coupled to the shaft wherein rotation of the drive gear causes rotation of the shaft; a first gear coupled to the gear plate; a floating gear coupled to the gear plate, wherein the floating gear can move from a first position to a second position, wherein when in the first position, the floating gear is coupled to the drive gear and to the first gear, and wherein when in the second position, the floating gear is decoupled from the drive gear; a pulley; a pinion gear coupled to the pulley and to the first gear, wherein rotation of the pulley causes rotation of the pinion gear and thereby rotation of the first gear; a torsion spring coupled to the pulley and to the housing, wherein rotation of the pulley torques the torsion spring; and a string wound around the pulley.
