Exercising ball

Exercising ball description/claims

1. Field of the Invention

This invention relates to an exercising ball, more particularly to an exercising ball that can be used for a variety of exercises.

2. Description of the Related Art

Referring to FIG. 1, a conventional exercising ball 1, which is hollow and spherical, allows a user 2 to perform different kinds of exercises on the ground. For example, the user 2 may rest his/her back 21 on the exercising ball 1 and to bend his/her upper body, thereby training his/her abdominal muscles 22. As another example, referring to FIG. 2, the user 2 may rest his/her hip 23 on the exercising ball 1 with his/her face facing downward and with his/her two feet 25 leaving the ground, while supporting himself/herself with his/her two hands 24, after which the user 2 may crawl forward and backward to train his/her arms muscles.

Although the exercising ball 1 can achieve its intended purpose, it still has the following drawbacks:

1. The exercising ball 1 is suitable only for exercises on the ground, and is too light in weight, such that when the exercising ball 1 is lifted off the ground to do lifting exercises or to do throwing exercises, it is very difficult to achieve an exercising effect. Hence, only a very few limited exercises may be performed with the exercising ball 1.

2. These exercises on the ground are very monotonous which may lead to boredom.

3. During use of the exercising ball 1, when the attention of the user 2 is distracted or when the user 2 changes his/her position, the exercising ball 1 rolls away easily and quickly, so that the user 2 has to chase it and pick it up so as to continue his/her exercise.

4. Since the exercising ball 1 rolls away easily, the user 2 is likely to fall off the exercising ball 1 during use of the same, which may cause injury to the user 2. Hence, the exercising ball 1 is not safe to use.

FIG. 3 illustrates a conventional weighted exercising ball 3, which has a spherical hollow ball body 31 that is filled with sand (not shown). The user 2 grips the weighted exercising ball 3 with his/her one hand 21 to do different moving or lifting exercises. Although the weighted exercising ball 3 can be used to perform many exercises, the exercises using the weighted exercising ball 3 are still monotonous and boring.

FIG. 4 illustrates a conventional arm exerciser 4, which has a hard ring-shaped tube 41, and a plurality of steel balls 42 disposed rollably in the tube 41. The user (not shown) grips the tube 41, and moves the arm exerciser 4 along a circular track so that the steel balls 42 roll around the tube 41. Since the arm exerciser 4 cannot be used for non-circular track exercises, the arm exerciser 4 is similarly monotonous and boring.

Therefore, the object of the present invention is to provide an exercising ball that is capable of overcoming the aforementioned drawbacks of the prior art. According to this invention, an exercising ball comprises an inflatable ball body made of an elastic material and defining a chamber, and a moving element disposed movably in the chamber.

Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments of the invention, with reference to the accompanying drawings, in which:

FIG. 1 is a schematic side view, illustrating one type of exercise performed using a conventional exercising ball;

FIG. 2 is a view similar to FIG. 1, but illustrating another type of exercise performed using the conventional exercising ball;
