Abstract

A board apparatus for balance exercises and balance games having a platform that tiltable on a base part, freely rotatable around a vertical axis, and mounted movably along the vertical axis. A restoring part generates restoring forces that counteract motions of the platform and can be modified by the user. The restoring part includes four elastomer springs that are arranged at a distance from the center of the base part. The elastomer springs can be offset inward or outward with respect to the center of the base part, enabling accurate adaptation of the restoring forces. When twisting the platform around the vertical axis, the restoring part always returns the support part into one of two initial positions that are located 180 degree opposite to one another.
