Abstract
An exercise apparatus which includes a ring shaped cushion member dimensioned and configured to freely allow a human torso to enter therein in generally axially aligned relationship and with clearance about at least a portion of the associated human torso. The apparatus includes structure for supporting the ring shaped cushion member for rotational movement about the axis thereof and structure for receiving the feet of a user disposed in axial spaced relationship from the ring shaped cushion member.
Claims21
An exercise apparatus which comprises:
- a ring shaped cushion member dimensioned and configured to freely allow a human torso to enter therein in generally axially aligned relationship and with clearance about at least a portion of the associated human torso;
- means for supporting said ring shaped cushion member for rotational movement about the axis thereof, said means for supporting said ring shaped support member for rotational movement about the axis thereof including means for varying the inclination thereof, internal cushioning disposed about the internal surface of said ring shaped cushion member, said means for supporting said ring shaped cushion member for rotational movement about the axis thereof including a trackway, a plurality of rollers, and a snubbing apparatus for limiting rotational movement of said ring shaped cushion member;
- means for receiving the feet of a user disposed in axially spaced relationship from said ring shaped cushion member, said means for receiving the feet of the user including shoe like members, said shoe like members include a depending plate shaped member, each of said plate shaped members including a bore, said means for receiving the feet including a pivot bar having axial extremities dimensioned and configured for engaging one of said bores;
- said means for supporting said ring shaped cushion member including first and second stub axles and generally vertical upright support members cooperating therewith, said upright support members including means for varying the elevation thereof, said means for varying the elevation including first and second worm gears and electric motor drive means for driving said worm gears;
- said means for receiving the feet of a user including a swivel bar, and means for mounting said means for receiving the feet of a user which allows relative axial movement of said means for receiving with respect to said ring shaped cushion member, said means for mounting said means for receiving includes means for positioning said means for mounting said means for receiving in a plurality of discrete positions, at least some of said discrete positions being disposed in radially spaced relationship from the axis of said ring shaped cushion members, said means for mounting said means for receiving the feet of a user allowing rotational movement;
- and
- further including an auxiliary support for the upper body of the user, said auxiliary support comprises an endless belt.

An exercise apparatus for use by a human being, which comprises:
- a ring shaped cushion member, having an axis, dimensioned and configured to support one side of a human torso in generally axially aligned relationship with said cushion member and in shaped relationship to any other side of the associated human torso;
- means for supporting said cushion member in a generally horizontal position for free rotational movement about the axis thereof, said cushion member being adapted to be moved rotationally only in response to forces imposed by the user;
- and
- means for receiving and securing the feet of a user disposed in axially spaced relationship from said ring shaped cushion member.
