Exercising ball holder

BACKGROUND OF THE INVENTION

[0001] The present invention is related to an exercising ball holder for fixing an exercising ball and locking elastic cords. It can ensure safety in use of the exercising ball. The position of the elastic cords can be quickly changed so as to achieve various exercising effects. Moreover, the exercising ball holder has simple structure and is manufactured at low cost.

[0002]FIGS. 1 and 2 show a conventional exercising ball <b>40</b> (usually called “Swiss ball” that is a big elastic plastic ball). The outer diameter of the exercising ball <b>40</b> is generally between 45 and 120 cm. A typical exercising ball <b>40</b> has an outer diameter between 50 and 80 cm. With respect to an exercising ball that has a 60-cm outer diameter, a user can sit thereon. Alternatively, the user can lie thereon. Even this user can face down, face up, or face laterally. However, the exercising ball <b>40</b> tends to roll away easily. So, the user is very likely to accidentally slip down or fall down and then gets hurt.

[0003] Furthermore, if the exercising ball <b>40</b> is used with an elastic cord (not shown), not only it is hard to fix the exercising ball <b>40</b> at a desire location, but also there is no place for locking the elastic cord. As a result, a user must carefully keep balanced and hold two ends of the elastic cord by both hands to exercise. It significantly limits the variety of the exercise patterns for the exercising ball <b>40</b> and the cooperative elastic cord.

SUMMARY OF THE INVENTION

[0004] It is therefore a primary object of the present invention to provide an exercising ball holder for preventing the exercising ball from randomly rolling. The exercising ball holder also is able to lock elastic cords so that the safety in use of the exercising ball can be ensured.

[0005] It is a further object of the present invention to provide the above exercising ball holder in which the position of the elastic cords can be quickly changed so as to achieve various exercising effects.

[0006] It is still a further object of the present invention to provide the above exercising ball holder that has simple structure and is manufactured at low cost.

[0007] The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] FIGS. <b>3</b> to <b>5</b> show the first embodiment of this invention. The exercising ball holder of the present invention mainly includes a base seat <b>10</b>, multiple extension arms <b>20</b> and at least one elastic cord <b>30</b>.

[0016] The base seat <b>10</b> is formed with a substantially concave rest depression <b>11</b> having an opening facing upward. A lower end of the exercising ball <b>40</b> is rested and located in the depression <b>11</b> without easily rolling out. The depression <b>11</b> is defined by a concave thin wall.

[0017] In order to prevent the exercising ball <b>40</b> from easily rolling out of the holder and to keep a user normally exercising with the exercising ball <b>40</b>, the horizontal maximum inner diameter D1 of a top edge of the depression <b>11</b> is between 20 and 60 cm. For example, assuming that the horizontal maximum inner diameter D1 of the present invention is 40 cm and the diameter D2 of the exercising ball <b>40</b> is 60 cm; the lower end of the exercising ball <b>40</b> can be stably fixed without randomly rolling. If the exercising ball <b>40</b> is slightly smaller (for example, 50 cm) or slightly larger (for example, 70 cm), the exercising ball <b>40</b> still can be stably located.

[0018] The multiple extension arms <b>20</b> respectively outward horizontally extend from the base seat <b>10</b>. (The extension arms <b>20</b> can be fixed with the base seat <b>10</b> by screws, locking elements, adhesive or integrally formed with the base seat <b>10</b>.) The free end <b>21</b> of each extension arm <b>20</b> has a fixing loop section <b>22</b>. In this embodiment, the free end <b>21</b> of each extension arm <b>20</b> is formed with a locking hole <b>211</b> for fixing a locking member <b>51</b>. A fabric plate <b>52</b> formed with a central through hole <b>521</b> is disposed at the free end <b>21</b>. The fixing loop section <b>22</b> is disposed on the fabric plate <b>52</b>. The locking member <b>51</b> can insert into the locking hole <b>211</b> via the central through hole <b>521</b> so that the fabric plate <b>52</b> is connected to the corresponding extension arm <b>20</b>.

[0019] Generally there are two elastic cords <b>30</b>. Each elastic cord <b>30</b> has a first end <b>31</b> and a second end <b>32</b>. The first end <b>31</b> is equipped with a hook section <b>311</b> (that can be easily released or locked) for fixedly connecting with the loop section <b>22</b>. The second end <b>32</b> has a handle <b>321</b> for a user's hand to hold.

[0020] The bottom face of the base seat <b>10</b> is formed with multiple channels <b>12</b> for the extension arms <b>20</b> to insert therein. The extension arms <b>20</b> can be secured by screws. Alternatively, the extension arms <b>20</b> can be fixed with the base seat <b>10</b> by locking elements, tight fitting, adhesive or just integrally formed with the base seat <b>10</b>.

[0021] In operation of the present invention, referring to FIG. 5, the four extension arms <b>20</b> are respectively positioned on front, rear, left and right sides of the user. Two elastic cords <b>30</b> are fixed on the front and rear (or left and right) extension arms <b>20</b>. Then the user can sit on exercising ball to keep balanced and exercise his/her arms. Alternatively, these two elastic cords <b>30</b> can be fixed on the front and left or rear and right extension arms <b>20</b>. Or, both the elastic cords <b>30</b> can be fixed on the front extension arms <b>20</b>. Still alternatively, the user can change the sitting position into lying position. That is, the user can face down, up or laterally. Thus, various exercising patterns are achievable.

[0022] The exercising ball <b>40</b> is fixed without randomly rolling so that the safety in use of the exercising ball <b>40</b> is ensured and the user is prevented from slipping down or falling down.

[0023]FIG. 6 is a top view that shows the second embodiment of the present invention, in which the depression <b>11</b> is defined between multiple curved thin plates that are radially arranged as the walls of the depression <b>11</b>. This also can fix the exercising ball <b>40</b> as the way in the first embodiment.

[0024]FIG. 7 shows the third embodiment of the present invention. For each extension arm <b>20</b>, the fixing loop section <b>22</b> is directly disposed on the free end <b>21</b> of the extension arm <b>20</b>.

[0025] In conclusion, the present invention is able to fix the exercising ball and the elastic cords. It can be used to exercise the muscle of a user's arms under a save condition. Furthermore, the position of the elastic cords can be quickly changed so as to achieve various exercising effects. Moreover, the present invention has simple structure and is manufactured at low cost.

[0026] The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
