Abstract

Applicant'"'"'s invention discloses an inclined platform which rotates freely upon a base having an annular ring with at least three legs extending between the annular ring and an inclined collet. The inclined collet has an upper tapered bearing race and a lower bushing sized to rotatably receive a shaft mounted perpendicular to the underside of the inclined platform. The inclined platform is preferably covered with a pliable material with padding extending between the pliable material and the top side of the inclined platform. Flexible handles extend from opposing sides of the inclined platform to aid in supporting the user thereon. The user shifts their body weight to rotate the inclined platform, thus spinning the user about the base.

Claims

1. A rotating platform apparatus, comprising:

a) a base formed of an annular ring supporting at least three legs, which are secured at one end to the annular ring, and at the other end to an inclined collet having an inclined collet aperture therethrough, the inclined collet further having an upper end and a lower end, a tapered bearing race is disposed upon the upper end of the inclined collet in concentric alignment with the inclined collet aperture; and

b) an inclined platform having a top side and an under side with a circumferential edge located between the top side and the underside, forming a substantially circular configuration of a size suitable to support a user thereon, the under side of the inclined platform having a shaft secured about an axis of rotation, perpendicular to the underside of the inclined platform, the shaft sized to be rotatably received within a tapered bearing upon the upper end of the inclined collet, and extending within the inclined collet aperture to rotatably engage a lower bushing located at the lower end of the inclined collet.

2. The rotating platform apparatus of claim 1, wherein flexible handles are secured upon opposing sides of the inclined platform.

3. The rotating platform apparatus of claim 1, wherein the top side of the rotating platform is covered with a pliable material for comfort.

4. The rotating platform apparatus of claim 3, wherein a padding material is disposed between the pliable material and the top side of the rotating platform for additional comfort.

5. The rotating platform apparatus of claim 1, wherein flexible handles are secured upon opposing sides of the inclined platform.

6. The rotating platform apparatus of claim 1, wherein three legs extend between the annular ring and the inclined collet of the base.

7. The rotating platform apparatus of claim 1, wherein the inclined platform is larger than the base.

8. The rotating platform apparatus of claim 1, wherein the inclined collet is preferably inclined at a fixed angle in relation to the annular ring, said fixed angle being from fifty-five degrees to eighty-five degrees above the annular ring of the base.

9. A rotating platform apparatus, comprising:

a) a base formed of an annular ring supporting at least three legs, which are secured at one end to the annular ring, and at the other end to an inclined collet having an inclined collet aperture therethrough, the inclined collet further having an upper end and a lower end, a tapered bearing race disposed upon the upper end of the inclined collet in concentric alignment with the inclined collet aperture; and

b) an inclined platform having a top side and an under side with a circumferential edge located between the top side and the underside, forming a substantially circular configuration of a size suitable to support a user thereon, the under side of the inclined platform having a shaft secured about an axis of rotation, perpendicular to the underside of the inclined platform, the shaft sized to be rotatably received within a tapered bearing sized to be received within the tapered bearing race located upon the upper end of the inclined collet, and extending within the inclined collet aperture to rotatably engage a lower roller bearing located at the lower end of the inclined collet, the top side of the inclined platform sized to be larger than the annular ring of the base.

10. The rotating platform apparatus of claim 9, wherein the inclined platform shaft is removably received within the inclined collet aperture, for ease of transport and storage.

11. The rotating platform apparatus of claim 9, wherein the top side of the rotating platform is covered with a pliable material for comfort.

12. The rotating platform apparatus of claim 11, wherein a padding material is disposed between the pliable material and the top side of the rotating platform for additional comfort.

13. The rotating platform apparatus of claim 9, wherein flexible handles are secured upon opposing sides of the inclined platform.

14. The rotating platform apparatus of claim 9, wherein three legs extend between the annular ring and the inclined collet of the base.

15. The rotating platform apparatus of claim 9, wherein the inclined collet is inclined at a fixed angle in relation to the annular ring, said fixed angle being from fifty-five degrees to eighty-five degrees above the annular ring of the base.

16. A rotating platform apparatus, comprising:

a) a base formed of an annular ring supporting at least three legs, which are secured at one end to the annular ring, and at the other end to an inclined collet having an inclined collet aperture therethrough, the inclined collet further having an upper end and a lower end, a roller bearing race is disposed upon the upper end of the inclined collet in concentric alignment with the inclined collet aperture, the inclined collet is inclined at a fixed angle being from fifty-five degrees to eighty-five degrees above the annular ring of the base;

b) an inclined platform having a top side and an under side with a circumferential edge located between the top side and the underside, forming a substantially circular configuration of a size suitable to support a user thereon, the under side of the inclined platform having a shaft secured about an axis of rotation perpendicular to the underside of the inclined platform, the shaft sized to be rotatably received within a roller bearing disposed upon the upper end of the inclined collet, the shaft extending within the inclined collet aperture to rotatably engage a lower roller bearing located at the lower end of the inclined collet; and

c) flexible handles secured upon opposing sides of the inclined platform.

17. The rotating platform apparatus of claim 16, wherein the inclined platform shaft is removably received within the inclined collet aperture, for ease of transport and storage.

18. The rotating platform apparatus of claim 16, wherein the top side of the rotating platform is covered with a pliable material for comfort.

19. The rotating platform apparatus of claim 16, wherein a padding material is disposed between the pliable material and the top side of the rotating platform for additional comfort.

20. The rotating platform apparatus of claim 16, wherein three legs extend between the annular ring and the inclined collet of the base.
