Abstract: An exercising and/or amusement device operably by the hands and feet of the user has first and second platforms rigidly spaced from each other adapted to receive one of the feet of the user. A ground engaging element is below and associated with each platform and has a bottom surface for selectively engaging the ground surface. A pivotable joint connects the platform and its associated ground engaging element. The connector has a curved surface on the platform spaced from the pad and a curved surface on the ground engaging element spaced from the bottom surface. The curved surface of the platform has an opening and the curved surface of the ground engaging element each having an opening therethrough. A bolt extends from the curved surface of the ground engaging element and through the opening in the curved surface of the platform for controlling relative movement between the curved surfaces.

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.

Abstract: First and second pads are connected by a member which is wider at the bottom than at the top. Each pad has a ground engaging element associated therewith. A generally semi-spherical bearing is provided between each ground engaging element and its associated pad so that the pads may tilt and/or rotate relative to their ground engaging element. A removable insert is provided for limiting maneuverability and thereby facilitating ease of maintaining balance by beginners.
