<p>An exercising and or amusement device supported by a ground surface and on which a person may stand. The device includes a walking beam (14) having first and second platforms (12) at opposite ends thereof for supporting the feet of a person, each platform having an upper surface adapted to support one of the person s feet. A ground engaging element is associated with each platform. Each ground engaging element has a bottom surface (18) for engaging a ground surface, a hemispherical supporting surface (20) and a pin (22) extending from the hemispherical supporting surface. Each platform is pivotally connected to an associated ground engaging element by a pivotable connection including a curved concave bottom surface on each platform shaped complementary to the hemispherical supporting surface of the associated ground engaging element and having a slot therein through which the pin of the associated ground engaging element extends. A plurality of resilient members engages the pin and urges it toward a neutral position. The resilient members are oriented such that extension of at least one of the resilient members applies a restoring force to the pin along a longitudinal axis of the walking beam.</p> |
