Axle-mounted wheel exercising device with spring resistance located centrally within the wheel

Claim 1

An exercise device of the type described, said device adapted to support the weight of the body of a user thereof, comprising: i. a wheel; ii. an axle mounted centrally for and through said wheel about which said wheel rotates; iii. said axle passing laterally through said wheel and extending from each side of said wheel for a distance sufficient for each laterally extending portion of said axle to be respectively grasped and held in the hands of a user of the device so that said wheel when said device is so grasped is between the hands of the user and, when so held and employed for body support, said device is adapted to be moved and rolled back and forth on and over a supporting surface in a direction substantially parallel with the torso of the user of the device; iv. at least a single spring means central within the circumference of the wheel in operative association with said wheel and axle for increasingly resisting rotation of the wheel with and upon increasing rotation of the wheel while said central axle is held and graspEd by the user so as to avoid rotation of said axle during rotation of the wheel therearound; v. mounting and affixing means on said wheel and on said axle for connecting the outer and inner ends of said spring means respectively to said wheel and said axle; with vi. one and the inner end of each of said spring means secured to and by the mounting and affixing means therefor on said axle; vii. the other and the outer end of each of said spring means secured to and by the mounting and affixing means therefor on said wheel; and viii. both said spring means and said axle and wheel mounting and affixing means therefor disposed and positioned within the circumference of the wheel and also within the side limits of the central radial planar configuration of the wheel.
