Ball and frame exercising apparatus

摘要

A resilient exercising ball is confined within a frame which defines a space around the ball so that the ball has limited universal movement. The ball is normally centered within the frame by elastic members or cords having end portions attached to the frame. The ball stretches the cords until the ball is supported by a base surface or floor, and the ball rolls horizontally within the space in response to movement of the person's body. The frame may be in the form of a rigid tubular chair with arm rests or in a circular configuration with a flexible ball support pad connected to the frame by elastic cords. The frame may also have a V-shaped configuration and be formed by releasably connected tubular sections having interfitting end portions.
