Never Tire™ exercise apparatus

Abstract

A tire-like exercise device having a substantially round outer periphery and a non-round inner periphery. The non-round inner periphery may be substantially rectangular and have one or more flat regions to provide hand and toe holds for performing various exercises. A first valve allows the firmness of the Never Tire exercise apparatus to be adjusted by increasing or decreasing inner air pressure. A second larger valve allows ballast, such as water or sand, to be input to the device to stabilize the apparatus against slipping and sliding.

Claims

1. An inflatable tire-like exercise device, said device comprising: a first element formed as an expandable bladder having a first substantially round outer periphery and a second non-round inner periphery of said same first element wherein a portion of said non-round inner periphery is substantially rectangular.

2. The exercise device of claim 1 wherein said non-round inner periphery includes substantially flat regions formed by undercut recesses providing hand and toe grips for performing various exercises.

3. The exercise device of claim 1 further comprising a first valve for adding and removing air to adjust a firmness of said device.

4. The exercise device of claim 3 further comprising a second valve for adding and removing ballast material.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The preferred embodiment(s) of the present invention is/are described in conjunction with the associated drawings in which like features are indicated with like reference numerals and in which

(2) FIG. 1 is a top perspective view of a first embodiment of the Never Tire exercise apparatus of the present invention;

(3) FIG. 2 is a front view of the first embodiment;

(4) FIG. 3 is a bottom perspective view of the first embodiment; and,

(5) FIG. 4 a cross-sectional bottom perspective view of the first embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

(6) A first embodiment of the Never Tire exercise apparatus of the present invention is depicted in FIGS. 1-4 generally at 20. Never Tire exercise apparatus 20 is a tire-like device having a substantially circular (round) outer periphery 22 and a non-round inner periphery. As seen in FIG. 3, on the bottom 36 of the device 20, the inner periphery 24b is substantially square. From the top 34 of the apparatus 20, the inner periphery appears substantially rectangular. This is the result of two flattened regions 26 that provide hand and foot holds for performing various exercises. Preferably, these hand/footholds have a slight lip or overhang 27 that facilitate gripping of regions 26. By engaging ones toes under overhang 27, sit-ups or other ab exercises may more easily be performed than say, with a conventional inner tube or truck tire.

(7) The cross-section shown in FIG. 4 depicts Never Tire exercise apparatus 20 as a thin-walled inflatable bladder which is preferably formed of soft PVC or other vinyl-like plastic materials. A first conventional valve has an external stem 30 that permits air to be added to or taken from the interior of the apparatus 20 to adjust the firmness of the device. A second larger diameter valve 32 permits water, sand, or other ballast material to be added to or taken from the interior. Such ballast will provide stability to the Never Tire exercise apparatus reducing the tendency to slip or slide as the participant works out on the device 20.

(8) Various changes, alternatives, and modifications will become apparent to a person of ordinary skill in the art after a reading of the foregoing specification. It is intended that all such changes, alternatives, and modifications as fall within the scope of the appended claims be considered part of the present invention.
