| titleOfInvention | Motorized ball toy with improved torque |
| abstract | Abstract of the Disclosure The invention provides a motorized ball toy with improved torque, traction and operating stability. The ball toy moves in response to internal motive power provided by a battery and motor mounted within the ball. The ball has two hemispheres which are joined together along their respective peripheral edges. A central shaft extends diametrically across the ball and is secured at each end by a shaft mount on the interior of each of the hemispheres. One of the shaft mounts releasably engages the central shaft and the other shaft mount nonrotatably engages the central shaft. A motor drive frame within the ball is supported on the central shaft. The drive frame is rotatable about the central shaft 360°. A motor on the drive frame imparts relative rotation between the drive frame and the central shaft which, in turn, drives the ball. An inert mass in the form of a zinc weight is attached to the drive frame at a predetermined distance from the central shaft to increase the torque imparted by the motor. The zinc weight is preferably curved and mounted at the extremity of the drive frame closest to the exterior wall of the ball, thereby maximizing the moment of inertia of the drive frame. |
