Abstract

An inertial exercise device includes a hollow outer ball and a weighted inner ball elastically suspended inside the outer ball by at least two opposing suspension members. The weighted inner ball may contain a fluid mass. The hollow outer ball, the weighted inner ball and the at least two opposing suspension members may all be integrally formed with each other. In one embodiment, the outer ball, the inner ball, and the suspension members are all formed from integral segments of a pliant tube. The hollow outer ball is formed by everting first and second end segments of the tube over the middle segment of the tube and joining the first and second end segments of the tube together at their openings. The weighted inner ball is formed from the middle segment of the tube which, in one embodiment, is a bulge in the tube.

Claims

1. An inertial exercise apparatus, comprising:

an inner ball elastically and concentrically suspended inside a hollow outer ball by a plurality of opposing suspension members,

wherein the inner ball is fillable with a fluid consisting of a liquid, gel, oil, or particulate from outside the hollow outer ball, and wherein at least one of the opposing suspension members comprises a neck segment through which the fluid can be delivered to the inner ball.

2. The apparatus according to claim 1, wherein when the inner ball is filled with a fluid consisting of a liquid, gel, oil, or particulate under pressure, the inner ball expands and increases tension in the plurality of opposing suspension members so as to increase resistance of motion of the inner ball relative to the hollow outer ball.

3. The apparatus according to claim 1, wherein the hollow outer ball and the inner ball are each integrally formed together from a pliant tube, comprising:

a middle segment with a maximum diameter equal to a first diameter; and

first and second end segments, each end segment dispose on opposite sides of the middle segment and terminating in an opening with a second diameter greater than the first diameter

wherein the hollow outer ball is integrally formed by everting the first and second end segments of the pliant tube over the middle segment and joining the first and second end segments together at their respective openings, and wherein the inner ball is integrally formed from the middle segment.

4. The apparatus according to claim 3, wherein the pliant tube further comprises:

a first neck disposed between the first end segment of the pliant tube and the middle segment of the pliant tube, the first neck having a first minimum inner diameter less than the first diameter; and

a second neck disposed between the second end segment and the middle segment, the second neck having a second minimum inner diameter less than the first diameter.

5. The apparatus according to claim 4, wherein the first minimum inner diameter is equal to the second minimum inner diameter.

6. The apparatus according to claim 5, further comprising a first watertight plug disposed in the first neck and a second watertight plug disposed in the second neck.

7. The apparatus according to claim 6, wherein the first watertight plug comprises a valve with a first position allowing fluid communication into the inner ball from outside the inner ball and a second position prohibiting fluid communication into the inner ball from outside the inner ball.

8. The apparatus according to claim 4, wherein the pliant tube has a variable wall thickness.

9. The apparatus according to claim 8, wherein the plurality of opposing suspension members has a variable elasticity dependent upon the wall thickness of the pliant tube adjacent to the first and second necks.

10. The apparatus according to claim 1, the hollow outer ball further comprising a first rigid outer shell with a first engagement edge and a second rigid outer shell with a second engagement edge, wherein the hollow outer ball is formed by engaging the first rigid outer shell to the second rigid outer shell at the first and second engagement edges, and wherein each engagement edge is configured to engage with the other engagement edge.

11. The apparatus according to claim 10, wherein the first and second engagement edge are each configured to engage through a threaded fastener engagement.

12. The apparatus according to claim 10, wherein the first and second engagement edge are each configured to engage through a snap fit engagement.

13. The apparatus according to claim 10, wherein the first and second engagement edge are each configured to engage through a press fit engagement.

14. The apparatus according to claim 10, wherein the plurality of opposing suspension members is integrally formed with an additional weight, and wherein the plurality of opposing suspension members is rigidly connected to a plurality of end anchors, each end anchor configured to anchor a respective opposing suspension member to the hollow outer ball.

15. The apparatus according to claim 14, wherein the plurality of end anchors is integrally formed with the plurality of opposing suspension members.

16. The apparatus according to claim 14, wherein the additional weight, the plurality of opposing suspension members, and the plurality of end anchors are integral parts of a single tube.

17. The apparatus according to claim 16, further comprising a bulge disposed in the single tube and a fill valve disposed on the plurality of end anchors, wherein the additional weight is formed by filling the bulge with a fluid through the fill valve.

18. The apparatus according to claim 10, wherein the inner ball is elastically and concentrically suspended inside the hollow outer ball by a plurality of radial suspension members configured to provide elastic suspension forces to the inner ball.

19. An exercise kit, comprising:

an inertial exercise apparatus comprising;

an inflatable outer chamber having an inner wall;

a fluid fillable inner chamber elastically and concentrically attached to the inner wall of the inflatable outer chamber by a plurality of opposing suspension members, at least one of the two opposing suspension members having a neck segment through which a fluid can be delivered to the fluid fillable inner chamber from outside the inflatable outer chamber;

a fill valve in fluid communication with the fluid fillable inner chamber and accessible from outside the inflatable outer chamber; and

a pump comprising a pump chamber in fluid communication with a pump hose, the pump hose terminating in a fitting engageable with the fill valve;

wherein the pump chamber is configured to enclose the apparatus when the inflatable outer chamber is deflated and the fluid fillable inner chamber is empty of fluid.

20. The apparatus according to claim 19, further comprising an air fill valve in fluid communication with the inflatable outer chamber, and wherein the fitting of the pump hose is engageable with the air fill valve.

21. An inertial exercise apparatus, comprising:

an inner chamber elastically suspended inside a hollow outer chamber by a plurality of opposing suspension members,

wherein the inner chamber is fillable with a fluid consisting of liquid, gel, oil, or particulate from outside the hollow outer chamber, and wherein at least one of the opposing suspension members comprises a neck segment through which fluid can be delivered to the inner chamber.
