EXERCISE DEVICE WITH SUSPENDED INERTIAL CORE
First Claim
1. An inertial exercise device, comprising:
- a hollow outer ball; and
an inner ball elastically and concentrically suspended inside the outer ball by at least two opposing suspension members, wherein the inner ball is fillable with a fluid mass;
wherein at least one of the suspension members comprises a neck segment through which the inner ball can be filled.

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 innerball 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.

15. An inertial exercise device, comprising:
-
a pliant tube, comprising; a middle segment having a maximum diameter equal to a first diameter; a first end segment and a second end segment on opposite sides of the middle segment, the first and second end segments each terminating in an opening with a second diameter greater than the first diameter; a first neck segment disposed between the first end segment of the tube and the middle segment of the tube, the first neck segment having a first minimum diameter less than the first diameter, the tube tapering from the first diameter of the middle segment to the first minimum diameter of the first neck segment and from the opening of the first end segment to the first minimum diameter of the first neck segment; and a second neck segment disposed between the second end segment of the tube and the middle segment of the tube, the second neck segment having a second minimum diameter less than the first diameter, the tube tapering from the first diameter of the middle segment to the second minimum diameter of the second neck segment and from the opening of the second end segment to the second minimum diameter of the second neck segment; wherein a hollow outer chamber is formed by everting the 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, wherein a weighted inner chamber is formed from the middle segment of the tube, and wherein the weighted inner chamber is elastically suspended inside the hollow outer chamber by the first and second neck segments of the tube. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of manufacturing an inertial exercise device, the method comprising:
-
providing a pliant tube with first and second open ends; forming a bulge in a middle segment of the tube, the bulge having a maximum diameter equal to a first diameter; forming an outwardly expanding first end segment between the bulge and the first open end of the tube, the first end segment increasing in diameter from the bulge to a first opening at the first open end of the tube, the first opening having a diameter equal to a second diameter greater than the first diameter; forming an outwardly expanding second end segment between the bulge and the second open end of the tube, the second end segment increasing in diameter from the bulge to a second opening at the second open end of the tube, the second opening having a diameter equal to the second diameter; everting the first and second end segments of the tube over the bulge in the middle segment of the tube and joining the first and second end segments of the tube together at the first and second openings to form a hollow outer chamber, wherein a weighted inner chamber is formed from the bulge in the middle segment of the tube, and wherein the weighted inner chamber is elastically suspended inside the hollow outer chamber. - View Dependent Claims (27, 28, 29, 30)

31. An exercise kit, comprising:
-
an inertial exercise device comprising; an inflatable outer chamber having an inner wall; a fluid fillable inner chamber elastically attached to the inner wall of the inflatable outer chamber by at least two opposing suspension members, at least one of the two opposing suspension members having a neck segment through which the inner ban can be filled; and 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 of the inertial exercise device; wherein the inertial exercise device is adapted to fit inside the pump chamber when the inflatable outer chamber of the inertial exercise device is deflated and the fluid finable inner chamber of the inertial exercise device is empty of fluid. - View Dependent Claims (32)
