Abstract
A balancing apparatus includes a platform that tilts upon a hemisphere attached to the lower surface thereof. The platform has a grooved track along its periphery. The outermost wall of the track is inclined. A ball is movable around said track upon tilting of the platform and can climb the outermost wall of the track when moved at a fast speed. The ball adds resistance to the tilting of the platform.
Claims13
A balancing apparatus comprising:
- a) a rigid platform having an upper surface and a lower surface, said upper surface comprising a center area large enough to accommodate the placement of one or two human feet, said center area surrounded by a grooved track, said grooved track having an inclined outermost wall;
- b) a pivoting mechanism attached to the lower surface of said platform to allow tilting of said platform on a support surface;
- and
- c) an object seated in said track such that said object is movable around said track upon tilting said platform can climb the outermost wall of said track when moving at a fast speed.

A balancing apparatus comprising:
- a) a rigid platform having an upper surface and a lower surface, said upper surface comprising a center area large enough to accommodate the placement of one or two human feet, said center area surrounded by a continuous grooved track, said grooved track having an outermost wall having an incline forming an angle with said platform of up to about 45 degrees;
- b) a pivoting means having a curved end and a flat end, said flat end attached to the lower surface of said platform adjacently beneath said center area;
- and
- c) an object seated in said continuous grooved track such that said object is moveable around said track upon tilting of said track and such that said object can climb the outermost wall of said track when moving at a fast speed.

A balancing apparatus comprising:
- a) a rigid platform having an upper surface and a lower surface, said upper surface comprising a center area large enough to accommodate the placement of one or two human feet, said center area having a diameter, said center area surrounded by a grooved track, said grooved track having an inclined outermost wall;
- b) a pivoting means having a curved end and a flat end, said flat end having a maximum diameter smaller than the diameter of said center area, wherein said flat end is attached to the lower surface of said platform adjacently beneath said center area;
- and
- c) a resistance means comprising at least one object seated in said grooved track, wherein said object is movable around said track upon tilting said platform such that said object can climb the outermost wall of said track when moving at a fast speed.
