  • Training roll-on ball with balancing supports
    Patent number: 4126326
    Abstract: This invention is a device to aid persons of varying ages to balance and move freely on a ball. The ball is set in a framework in such a manner that it may roll freely. The framework is mounted on casters so that said framework may move freely with the ball. In use, the rider moves about atop the ball, using the handles of the framework for support when necessary for balance. As the user gains skill, the framework may be dispensed with.
