ABSTRACT:
A balancing apparatus emulating the acrobatics associated with skate boards etc. having a rectangular platform, one or more hemispherical, pivotal fulcrums, rotational with respect to a rectangular platform, and a foot plate, attached to the fulcrum member. A single fulcrum may be used in conjunction with a truncated, conical, stationary member for encouraging parallel orientation of the platform. A detachable, restricting ring is also provided for reducing the angulation of the platform with the supporting surface during use. The user stands on one foot plate and attempts to maintain balance on the fulcrum member while manipulating the platform with the other foot, at the opposite end of the apparatus, which may also contain a fulcrum member or a stationary, conical member.
