Abstract
A balancing apparatus of the platform and spherical fulcrum type in which the spherical fulcrum is rotatable about its orthogonal axes to enable the fulcrum to move freely over a horizontal surface. A platform support on the spherical fulcrum has a first surface and oppositely facing second surface engaging the spherical fulcrum. A foot support is centrally located on the first surface. A stop means, for defining the extent of movement of the platform relative to the spherical fulcrum, is positioned on the second surface at a location outside the projection of the foot support from the first surface on the second surface.
