Abstract

A chair base with a platform, at least one support, at least one void, and at least one bowl. The platform has a flat top surface, a bottom surface opposite the top surface, and a plurality of sides bordering the top surface. Each side may extend downward past the bottom surface and inward toward a center of the platform. The support extends up from the top surface of the platform and is configured to support a seat of the chair above the platform. The void extends through the platform and the bowl is sized and shaped to sit within the void. The bowl has a lip configured to engage with a rim of the void and restrict the bowl from entirely passing through the platform. The bowl may be removable from the void. The platform may be mounted on at least three wheels to mobilize the chair base.

Claims (36)

1. A chair base comprising:

a planar, polygonal platform having a flat top surface, a bottom surface opposite the top surface, and a plurality of straight sides bordering the top surface, wherein each side extends downward past the bottom surface and inward toward a center of the platform;

at least three wheels configured to mobilize the chair base, wherein the platform is mounted on the at least three wheels;

a plurality of supports extending up from the top surface of the platform and configured to support a height adjustment mechanism above the platform, the height adjustment mechanism slidably coupled to a post supporting a seat of a chair and configured to control a height of the seat above the platform;

a plurality of polygonal voids extending through the platform, each of the plurality of voids positioned equidistantly from the center of the platform; and

a plurality of bowls sized and shaped to sit within the plurality of voids, each of the plurality of bowls having a lip configured to engage with a rim of a corresponding void of the plurality of voids and restrict each bowl from entirely passing through the platform, wherein each bowl is removable from the plurality of voids;

wherein a total number of the plurality of straight sides of the platform, a total number of the plurality of supports, and a total number of the plurality of voids are equal.

2. The chair base of claim 1 , wherein the top surface of the platform is textured to increase traction on the top surface.

3. The chair base of claim 1 , wherein the platform has a plurality of perforations extending through the platform, wherein each has a maximum dimension within a plane parallel with the top surface that is less than or equal to one inch.

4. The chair base of claim 1 , further comprising a central aperture extending through the center of the platform, the central aperture configured to allow an end of the post to pass through the platform.

5. A chair base comprising:

a planar platform having a flat top surface, a bottom surface opposite the top surface, and a plurality of sides bordering the top surface, wherein each side extends downward past the bottom surface and inward toward a center of the platform;

a plurality of supports extending up from the top surface of the platform and configured to support a seat of a chair above the platform;

at least three wheels configured to mobilize the chair base, wherein the platform is mounted on the at least three wheels;

at least one void extending through the platform; and

at least one bowl sized and shaped to sit within the at least one void, the at least one bowl having a lip configured to engage with a rim of the at least one void and restrict the at least one bowl from entirely passing through the platform, wherein the at least one bowl is removable from the at least one void.

6. The chair base of claim 5 , wherein the platform is polygonal.

7. The chair base of claim 5 , further comprising a height adjustment mechanism affixed to the plurality of supports, wherein the height adjustment mechanism is configured to control a height of the seat of the chair with respect to the platform.

8.

9. The chair base of claim 5 , wherein the at least one void and the at least one bowl are a plurality of voids and a plurality of bowls, respectively, and wherein each of the plurality of voids is positioned equidistantly from the center of the platform.

10. The chair base of claim 9 , wherein a total number of the plurality of sides of the platform, a total number of the plurality of supports, and a total number of the plurality of voids are equal.

11. The chair base of claim 5 , wherein the top surface of the platform is textured to increase traction on the top surface.

12. The chair base of claim 5 , wherein the platform has a plurality of perforations extending through the platform, wherein each perforation of the plurality of perforations has a maximum dimension within a plane parallel with the top surface that is less than or equal to one inch.

13. A chair base comprising:

a platform having a top surface, a bottom surface opposite the top surface, and a plurality of sides bordering the platform, wherein each side extends in a direction perpendicular to the top surface and inward toward a center of the platform;

a plurality of supports extending up from the top surface of the platform and configured to support a seat of a chair above the platform;

at least three wheels configured to mobilize the chair base, wherein the platform is mounted on the at least three wheels;

at least one void extending through the platform; and

at least one bowl sized and shaped to sit within the at least one void, the at least one bowl having a lip configured to engage with a rim of the at least one void and restrict the at least one bowl from entirely passing through the platform, wherein the at least one bowl is removable from the at least one void.

14. The chair base of claim 13 , wherein the platform is polygonal.

15. The chair base of claim 13 , further comprising a height adjustment mechanism affixed to the plurality of supports, wherein the height adjustment mechanism is configured to control a height of the seat of the chair with respect to the platform.

16. The chair base of claim 13 , wherein the seat of the chair is mounted on a post, wherein a distance between the seat of the chair and the platform is adjustable, and wherein the chair base further comprises a central aperture extending through the center of the platform, the central aperture configured to allow the post to pass through the platform.

17. The chair base of claim 13 , wherein the at least one void and the at least one bowl are a plurality of voids and a plurality of bowls, respectively, and wherein each of the plurality of voids is positioned equidistantly from the center of the platform.

18. The chair base of claim 17 , wherein a total number of the plurality of sides of the platform, a total number of the plurality of supports, and a total number of the plurality of voids are equal.

19. The chair base of claim 13 , wherein the top surface of the platform is textured to increase traction on the top surface.

20. The chair base of claim 13 , wherein the platform has a plurality of perforations extending through the platform, wherein each perforation of the plurality of perforations has a maximum dimension within a plane parallel with the top surface that is less than or equal to one inch.
