ABSTRACT:
An exercising and/or amusement device for receiving a person's feet and engaging a ground surface has a first and second platform spaced apart from each other. Each platform has an upper surface being adapted to receive one of the person's feet. A ground engaging element is associated with each of the platforms and has a dome-shaped bottom surface wherein the outer edge selectively engages the ground surface. A pivotable connector connects the platform and the associated ground engaging element and consists of a curved surface on the platform spaced from the upper surface. The element has a complimentary curved surface spaced from the bottom surface. The curved surfaces on the platform and ground engaging element slideably engage each other. The curved surface of the platform has a slot with its major axis extending along a longitudinal axis defined by an imaginery line between the platforms. A bolt extends from the curved surface of the ground engaging element and through the slot in the curved surface of the platform for limiting relative movement between the curved surfaces. A compression spring carried by the platform and encircling the bolt urges the curved surface of the ground engaging element into engagement with the curved surface of the platform and urges the ground engaging element towards a centering position relative to the platform.
