Abstract

An exercise apparatus includes a substantially flat, rigid platform for supporting a user during exercise. An inflatable tubular support having an upper portion with a first radial outside diameter, and a lower portion with a second radial outside diameter that is greater than the first radial outside diameter, is coupled to the platform by a fastener. The tubular support defines a central opening that communicates between the platform and a support surface. The platform includes a venting structure for releasing air from the central opening during use. The inflatable support includes an intermediate portion between the upper portion and the lower portion of the tubular support, the intermediate portion including a support feature to restrain the intermediate portion from radial expansion induced by an air pressure internal to the integral inflatable support.

Claims (25)

1. An exercise apparatus for use on a support surface comprising:

a rigid platform having a substantially closed top and a peripheral edge defining a vent opening;

an inflatable tubular support supporting the rigid platform whereby in use a central opening is defined between the support surface, an external surface of the inflatable tubular support, and the rigid platform; and

the closed top and the vent opening passing air laterally outwardly from the peripheral edge of the platform while preventing air from being directed toward the user.

2. The exercise apparatus of claim 1 wherein the vent includes a plurality of laterally outward facing openings formed into the rigid platform.

3. The exercise apparatus of claim 1 wherein the exercise apparatus is configured to pass air vertically from the central opening before passing the air laterally outwardly.

4. The exercise apparatus of claim 1 wherein the inflatable tubular support includes two inflatable tubular portions including an upper tubular portion for engaging the rigid platform and a lower tubular portion for engaging the support surface.

5. The exercise apparatus of claim 1 wherein the inflatable tubular support includes an integral affixing member and further comprising a fastener clamping the integral affixing member to the rigid platform.

6. An exercise apparatus for use on a support surface comprising:

an inflatable tubular support having a wall surrounding an internal air chamber having an outer peripheral wall portion and an inner wall portion, the inner wall portion separates a central opening from the internal air chamber; and

a rigid platform supported by the inflatable tubular support, the rigid platform having a closed top and a peripheral edge defining a vent opening facing radially outwardly from the platform, whereby the rigid platform passes air radially outwardly from the platform while preventing air from being directed upwardly toward the user.

7. The exercise apparatus of claim 6 wherein the rigid platform includes an upper portion and a lower portion defining a venting structure including the vent.

8. The exercise apparatus of claim 6 wherein the platform defines a venting structure including vertical ducts that allow air to pass vertically from the central opening into the rigid platform before being released through the vent.

9. The exercise apparatus of claim 6 wherein the platform includes a plurality of features that rigidify the platform.

10. The exercise apparatus of claim 9 wherein the plurality of features includes a rib defining a notch allowing air to pass through the rigid platform to the vent.

11. The exercise apparatus of claim 6 wherein the inflatable tubular support includes two inflatable tubular portions including an upper tubular portion for engaging the rigid platform and a lower tubular portion for engaging the support surface.

12. The exercise apparatus of claim 6 wherein the inflatable tubular support includes an integral affixing member and further comprising a fastener clamping the integral affixing member to the rigid platform.

13. An exercise apparatus for use on a support surface comprising:

an inflatable tubular support having an inner wall portion surrounding an internal air chamber separating a central opening from the internal air chamber and an outer peripheral wall portion; and

a rigid platform coupled to the inflatable tubular support, the rigid platform defining a venting structure including a peripheral vent and configured to pass air upwardly from the central opening and then redirecting the air radially outwardly from the peripheral vent thereby preventing air from being directed upwardly toward the user.

14. The exercise apparatus of claim 13 wherein the rigid platform includes an upper portion and a lower portion with the venting structure formed therebetween.

15. The exercise apparatus of claim 14 wherein a vertical duct is formed into the lower portion of the rigid platform.

16. The exercise apparatus of claim 14 wherein the lower portion includes a plurality of features to rigidify the platform.

17. The exercise apparatus of claim 16 wherein at least one of the plurality of features defines a notch to allow air to pass through the features.

18. The exercise apparatus of claim 14 wherein the peripheral vent is formed into the lower portion of the rigid platform.
