BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to exercise equipment, and more particularly to exercise balls and similar stationary exercise equipment.

2. Prior Art

Use of a large ball for exercising is well known in the art. Typically, such balls, known in the art as exercise or stability balls are very useful for developing the abdominal muscles and can also be used to develop other core muscle groups.

However, the spherical shape of an exercise ball is inherently unstable, making it easy for users to fall from the ball during exercise leading to injury, including head trauma. Users of exercise balls may try to increase the stability of the ball by using it while it is propped against a wall or other stable member. However, use of the exercise ball in such a way severely limits it usefulness and effectiveness.

Furthermore, exercise balls are also inherently clumsy to use and are generally limited to developing the core muscle groups. SUMMARY OF THE INVENTION

Referring now to Figures Ia-Ic, a first embodiment of a device is shown for use with an exercise ball, the device being referred to in general with reference numeral 100. Figure Ia shows the device 100 while Figure Ib shows the device 100 secured to an exercise ball 102. The exercise ball is a spherical elastomer ball that has an internal cavity that is generally inflated with air. Alternatively, the ball can be made of semi-rigid materials so inflation thereof is not necessary. The device 100 can be secured to the ball by any method known in the art, such as by mounting the device 100 with flexible straps 104 or fabricated integral with the ball. In general, the device can be for one or more of increasing a usefulness of the ball for performing a greater range of exercises than would be possible without the device; increasing a stability of the ball to minimize injuries resulting from use thereof; and increasing an easiness of use of the ball than would be possible without the device.

Specifically with regard to Figures Ia-Ic, the device 100 is particularly useful for increasing a usefulness of the ball 102. The device 100 includes a band 106 for attaching circumferentially around the ball 102 and secured to the ball 102 by means of the flexible straps 104. The band 106 can be a simple band or include further structure such as a second band 108 attached to the band 106 by way of attachment members 110 spanning between the band 106 and the second band 108. Such attachment members 110 can be rigid or have flexibility, such as being fabricated with spring steel or other biasing material.

A pair of armrest members 112 are secured to the band 106, such as by welding and can include features such as padded rests 114 and handgrips 116 for being grasped by a user. Each of the pair of armrest members can further comprise a height adjustment device 118, as are known in the art, for adjusting a height of the handgrip 116 relative to the ball 102. Figure Ic shows the height adjustment device 118 in greater detail and can include a series of openings 120 and a corresponding pin for engaging one of the openings. The pin can be biased in an extended position to keep it from coming out of the opening 120.

The armrest members 112 can be used to increase an easiness of use of the ball as well as increase the usefulness of the ball by providing holding members for a user to grasp and allowing additional exercises to be done on the ball 102. The ball can be further modified to add a liquid, such as water 122 (shown in phantom lines) to partially fill an interior volume of the ball to increase a stability of the ball by lowering its center of gravity.

Referring now to Figure 2a, there is shown another embodiment of a device for use with an exercise ball, referred to generally by reference numeral 200. Figure 2a illustrates a means for increasing a stability of an exercise ball 202 comprising three or more stability projections 204 integrally formed with an outer surface 206 of the ball 202. A single stabilizer can also extend around the entire circumference of the ball. Such stability projections 204 can be formed as a solid piece of elastomer or can be to at least some degree hollow. Also, the stability projections 204 can be molded integrally with the outer surface 206 of the ball 202 or be insert molded therewith. The stability projections 204 project radially out from the outer surface 206 of the ball 202 and can have a surface 208 adapted (shaped and sized) to contact a surface upon which the ball rests when the ball is rotated more than a predetermined amount. Thus, the stability projections 204 limit the amount of roll the ball can make, thereby limiting the range of motion possible. Such limited range provides stability to the ball 202 such that the user will not fall or be thrown off while using it and the user also does not have to be conscious of falling off the ball while using it and can thereby concentrate on the workout without additional worrying.

Referrring now to Figure 2b, there is shown another embodiment of a device for use with an exercise ball 102, the device being referred to generally by reference numeral 250. The device 250 helps to increase the stability of the ball 102 with the use of stabilizers 252 similar to those described with regard to Figure 2. However, such stabilizers 252 are secured to a band 254, which is attached circumferentially around the ball 102. The stabilizers 252 can be provided in any number, however three or more stabilizers can be used to provide a minimum amount of necessary stability. A single stabilizer can also extend around the entire circumference of the ball. The stabilizers 252 can project radially out from a portion of the band 254 and can also have a surface 256 adapted to contact the surface upon which the ball 102 rests. The stabilizers 252 can be formed in a plate-like shape or as a solid and secured to the band 254 by any means known in the art, such as by welding. The stabilizers 252 can also be formed integrally with the band 254. The device 250 can also be used for increasing an easiness of use of the ball by providing one or more handle members 258 secured to the band 254 and having at least one handgrip 260 for being grasped by a user. The handle members 258 can be secured to the band 254 by any means known in the art, such as by welding. The handle members can also be used to increase a usefulness of the ball 102.

Each of the individual stabilizing feet 304 can also comprise an extension adjustment mechanism 310 for adjusting an extension length of the stabilizing feet. Such adjustment mechanism can be any of those known in the art, including that previously described with regard to Figure Ic.

In the configuration of Figures 3 a and 3b, two pairs of stabilizing feet 304 are provided and secured to the ball 302. The stabilizing feet 304 can be angled with respect to each other as shown in Figure 3a and 3b and can also be rotatably secured to the ball 302. The means by which the stabilizing feet 304 are rotatably secured to the ball 302 can include a central shaft 312 (shown in phantom in Figure 3b) running through the ball 302 and connected at each end to the pairs of stabilizing feet 304. The ball 302 can be retrofitted with an inner tube through which the shaft 312 is disposed and sealed at its ends or molded with such a tube. The ball 302 can further include at least one handle 314 having at least one handgrip 316 for being grasped by a user. The handle 314 can be secured to the pairs of stabilizing feet 304 and can also include an adjustment for height and/or angle with respect to the ball as is shown generally at reference numeral 316 in Figure 3b.

The device 600 helps to increase a stability of the ball 602 and can comprise a ballast 604 adapted to be rotatably secured on an interior of the ball 604. The ballast includes an internal volume to sealingly contain one or a liquid, gel or solid. The ballast 604 can be secured to a rotatable shaft 606 rotatably secured through the ball 602 (similar to that described above with regard to Figures 3 a and 3b). The ballast 604 extends radially from the shaft 604 in a direction of gravity to lower a center of gravity of the ball 602 to increase the stability thereof. Due to the rotation of the ballast 604, the ballast 604 maintains its orientation of greatest stability when the ball rotates about the shaft 606. The shaft 606 can be secured through a diameter of the ball 602. The shaft can include a conduit 608 in communication with the internal volume of the ballast 604. The conduit can have an inlet 608a on an end of the shaft 606 for filling the one of the liquid, gel or solid into the internal volume. A cap 610 can be sealingly secured to the shaft 606 to seal the inlet 608a by any means known in the art such as by mating threads. The device 600 can further comprise one or more of a handle or body rest (together referred to by reference numeral 612) secured to the shaft 606 and rotatable therewith.

Referring now to Figures 7a-7c, there is shown a variation of the embodiment of Figures 6a and 6b, the device illustrated therein being generally referred to by reference numeral 700. hi the variation of Figures 7a-7b, the device is used with an exercise ball 702 and comprises a ballast 704 extending towards an inner surface 706 the shell 708 of the ball 702 to provide a very low center of gravity and additional stability. The ballast 704 is rotatably secured to the ball 702 by way of a shaft 710 which is rotatably secured to the ball 702 similarly to that described above. However, the shaft can be offset from a center diameter of the ball 702 away from the surface upon which the ball 702 rests (e.g., the floor). The shaft 710, as discussed above, can include a conduit and an inlet for filling an internal cavity of the ballast 704 with a liquid (e.g., water), gel and/or solid (e.g., sand). Thus, the ball 702 and device 700 can be used as is shown in Figure 7a with an increased stability.

The device 700 can also be used with modular handles 712 as shown in Figures 7b and 7c. Such modular handles 712 can be constructed of two or more pieces (712a-712c) which snap together as is known in the art, such as with a biased pin 714 and corresponding opening 716. At least one of the pieces (712c in Figure 7b) can include a handle grip 718 for being grasped by a user. The handles 712 can be manipulated into a variety of configurations (lengths and angles) to satisfy different height and/or sizes of users and/or different exercises being performed on the ball 702. The shaft 710 and handle can be provided with female and male connection fittings, 720a, 720b, respectively, to connect the handles 712 to the device 700. The device 700 can be used with one handle 712 or two as shown in Figure 7c.

Referring now to Figures 8a and 8b, there is shown an exercise device generally referred to by reference numeral 800. The device 800 comprises a base 802 for sitting on a surface such as the floor and a user platform 804 for holding a user of the device 800. The platform 804 can be configured in any way known in the art, such as a frame having a fabric stretched within the frame to support a user or as a solid member as shown in Figures 8a and 8b. The platform 804 can also include one or more handles for being grasped by the user. The handles can be configured in any way known in the art or as described above, such as handles 712 described with regard to Figures 7b and 7c. The device 800 includes a spring element 806, such as a compression spring for connecting the user platform 804 to the base 802 and allowing a restricted range of motion of the user platform relative to the base. Figure 8b illustrates an exemplary range of motion of the platform 804 relative to the base 802 in phantom lines. The device 800 can have similar exercise effects as an exercise ball without the inherent problems associated therewith, as discussed above. Although not shown, the device 800 can have a means for securing the user to the platform 804, such as a seatbelt and the base can be fillable with a liquid (e.g., water), gel or solid (e.g., sand) to increase its stability.
