Patent ID: 7118517

Claim:
An exercise apparatus comprising: a substantially spherical ball; a frame for rotatably supporting said substantially spherical ball in vertically spaced relation to a support surface; said frame including a pair of longitudinally disposed base members disposed in substantially parallel, transversely disposed in relation to one another; said frame including a leading transversely disposed base member that interconnects respective leading ends of said pair of longitudinally disposed base members; said frame including a trailing transversely disposed base member that interconnects respective trailing ends of said pair of longitudinally disposed base members; said frame including a first pair of support members secured to a first longitudinally disposed base member of said pair of longitudinally disposed base members; said frame including a second pair of support members secured to a second longitudinally disposed base member of said pair of longitudinally disposed base members; said first pair of support members having respective first ends secured to said first longitudinally disposed base member in longitudinally spaced apart relation to one another and having respective second ends that abut one another, said respective second ends being in vertically spaced relation to said respective first ends, said first pair of support members forming an inverted “V” configuration; said second pair of support members having respective first ends secured to said second longitudinally disposed base member in longitudinally spaced apart relation to one another and having respective second ends that abut one another, said respective second ends being in vertically spaced relation to said respective first ends, said second pair of support members forming an inverted “V” configuration; a first rotatably mounted connector disposed at an apex of said first pair of support members; a second rotatably mounted connector disposed at an apex of said second pair of support members in diametrically opposed relation to said first apex; said substantially spherical ball being positioned between said first and second pair of support members; said first and second rotatably mounted connectors engaging said substantially spherical ball at diametrically opposed points on said substantially spherical ball; said first and second support members having a common extent, said common extent being at least slightly greater than a radius of said substantially spherical ball so that said substantially spherical ball is free to rotate about an axis defined between said diametrically opposed points.
