Description

FIELD OF THE INVENTION

The present invention relates to exercise apparatus.

BACKGROUND OF THE INVENTION

A wide range of exercises are available to exercise various parts of the body in a standing position. While such exercises have traditionally been performed while standing on a solid surface, it has been realised that there are benefits to performing various exercises on a surface that has some degree of instability. The act of balancing during the exercise has been shown to provide useful additional exercise to a range of muscles.

Devices are available to provide such an unstable surface on which a person can exercise. On such example comprises the device sold under the trade name “Bosu Ball”. This device comprises an inflatable dome mounted to a base surface. The user can perform a range of exercises and stretches either standing or resting part of their body on the inflatable dome.

The present invention relates to an exercise apparatus of the type for providing an unstable surface on which a person can perform various exercises having an improved construction to assist with both usability and transport and storage.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to Figures, there is shown an exercise apparatus 10 in accordance with the present invention. The exercise apparatus 10 comprises a first rigid member 12, a second rigid member 14 and one or more resilient members 16 located between the first and second rigid members 12 and 14.

In the embodiment shown, the first rigid member 12 comprises a first planar member of generally rectangular shape. The second rigid member 14 comprises a second planar member of generally rectangular shape. The first planar member includes a first surface 18 to rest on the ground in use and a second surface 19 oriented upwardly. The second planar member 15 is located above the first planar member 15 and includes a first surface 18 arranged facing upwardly and a second surface 19 oriented downwardly towards the second surface 19 of the first planar member.

The resilient members 16 are provided between the first and second planar members and 15 such that when the first planar member rests on the ground, the second planar member 15 is supported above the first planar member. That is, the resilient members 16 rest on the second surface 19 of the first planar member and the second surface 19 of the second planar member 15 rests on top of the resilient members 16.

In the embodiment shown, there are provided two resilient members 16. Each resilient member 16 is provided in the form an inflatable member 17. In the embodiment shown, each inflatable member 17 comprises an inflatable cylinder. It will be appreciated however that the inflatable members 17 may be formed in other shapes, such as spherical.

The second surfaces 19 of the first and second planar members and 15 each include a first recess 20 and second recesses 21 therein. The first recess 20 is provided between a midpoint of the second surface 19 and a first end thereof. The second recess 21 is provided between the midpoint of the second surface 19 and a second opposite end thereof. The first of the inflatable members 17 is received in the first recess 20 of the first planar member and the first recess 20 of the second planar member 15. The second of the inflatable members 17 is received in the second recess 21 of the first planar member and the second recess 21 of the second planar member 15.

Each of the inflatable members 17 is connected to the second surfaces 19 of the planar members and 15 within the recesses 20 and 21. Each inflatable member 17 includes a first cylindrical portion 22 at a first end thereof and a second cylindrical portion 23 on a second opposite end thereof. Each of the first and second cylindrical portions 22 and 23 includes a flange 24 around the periphery of the distal end thereof.

Associated with each of the flanges 24 is a securing ring 26. The internal diameter of each securing ring 26 is less than the external diameter of the flanges 24. Each flange 24 is compressible such that it can be compressed to be received within the securing ring 26. The securing ring 26 is then affixed to the adjacent planar member or 15 by suitable means such as securing screws 27. The securing rings 26 are secured such that the first and second end portions 22 and 23 of each of the inflatable members 17 are secured within the respective recesses 20 and 21. The recesses 20 and 21 are generally cylindrical in shape having a circular planar inner surface to which the securing rings 26 are secured.

Each of the first and second planar members and 15 is provided with a cover 28. The covers 28 are provided to extend over at least a portion of the first surfaces 18 of the first and second planar members and 15. The covers 28 are constructed of a material for providing grip when a user stands on the cover 28. The covers 28 may also include surface features for providing such grip.

The second surfaces 19 of each of the first and second planar members and 15 are provided with one or more connectors such that the connectors on the first planar member can engage with the connectors on the second planar member 15 when the inflatable members 17 are deflated. As shown in FIG. 9, when the inflatable members 17 are deflated, the second surfaces 19 of the first and second planar members and 15 can engage and the deflated inflatable members 17 are received between the recesses 20 and 21.

The connectors comprise first connectors 30 provided on the second surfaces 19 of the first planar member and second connectors 31 provided on the second surface 19 of the second planar member 15. In the embodiment shown, there is provided a pair of first connectors 30 adjacent the first end of the first planar member and a pair of first connectors 30 provided adjacent the second end of the first planar member. A pair of second connectors 31 is provided adjacent the first end of the second planar member and a pair of second connectors 31 is provided adjacent the second end of the second planar member 15. Each of the first connectors 30 is provided to engage with a corresponding one of the second connectors 31.

The shape of each of the first connectors 30 is complementary to the shape of the corresponding second connector 31 such that the first connector 30 can engage with the corresponding second connector 31. In the embodiment shown, each of the first connectors 30 comprises a protruding portion 40 and a recessed portion 41 (as best seen in FIG. 9b). Each of the second connectors 31 also comprises a protruding portion 40 and a recessed portion 41. The protruding portions 40 and recessed portions 41 define a generally S-shaped surface.

The protruding portion 40 of each of the first connectors 30 engages into the recessed portion 41 of the corresponding second connector 31 and the recessed portion 41 of each of the first connectors 30 receives the protruding portion 40 of the corresponding second connector 31 (as can be seen in FIG. 9). The shape and orientation of the S-shaped surfaces are such that the first and second connectors engage together in a snap fit manner with application of sufficient force to retain the first and second planar members and 15 together for transport and/or storage. The first and second connectors 30 and 31 can be disengaged by pulling the first and second planar members and 15 apart with sufficient force.

In use, the exercise apparatus 10 is placed on the ground with the inflatable members 17 inflated to the desired pressure. As shown in FIG. 5, a person can stand on the first surface 18 of the second planar member 15 and perform various exercises. The resilient nature of the inflatable members 17 results in movement of the second planar member 15 relative to the first planar member. The person performing the exercises must therefore compensate for this movement while exercising, thereby providing an enhanced workout.

It will be readily apparent to persons skilled in the relevant arts that various modifications and improvements may be made to the foregoing embodiments, in addition to those already described, without departing from the basic inventive concepts of the present invention.
