Balancing exercise devices

Abstract

A balancing exercise device has a central balancing member having a center of balance. A first foot pad is coupled to the central balancing member on a first side of the center of balance. The first foot pad is pivotable with respect to the central balancing member. A second foot pad is coupled to the central balancing member on an opposite, second side of the center of balance. The second foot pad is pivotable with respect to the central balancing member. An application of equal forces on the first and second foot pads balances the central balancing member with respect to the center of balance. An application of unequal forces on the first and second foot pads causes the central balancing member to pivot about the center of balance until one of the first and second foot pads engages with a support surface on which the central balancing member is supported.

DETAILED DESCRIPTION OF THE DRAWINGS

FIGS. 1-3 depicts a balancing exercise device 10 according to the present disclosure. The balancing exercise device 10 has a central balancing member 12 that is capable of being balanced with respect to a support surface 14 about a center of balance 16. A first foot pad 18 is coupled to the central balancing member 12 on a first side 20 of the center of balance 16. A second foot pad 22 is coupled to the central balancing member 12 on an opposite, second side 24 of the center of balance 16. As will be discussed further herein below, the first and second foot pads 18, 22 have planar top surfaces 19, 21 and are configured to support a user's feet 46, 48 (see FIGS. 2 and 3) as the user stands on the planar top surfaces 19, 21 and adjusts his or her weight back and forth on his or her feet 46, 48. Adjustment of the user's weight back and forth on his or her feet 46, 48 balances the balancing exercise device 10 with respect to the center of balance 16 and/or rocks the balancing exercise device 10 back and forth about the center of balance 16. By balancing and/or rocking the balancing exercise device 10 back and forth, the user exercises both upper and lower extremity groups, either individually or simultaneously.

The central balancing member 12 has a bottom surface 26 that is configured to abut the support surface 14. The bottom surface 26 has a centrally located contact location 28 about which the center of balance 16 is defined. The shape and configuration of the central balancing member 12 can be different than what is illustrated. In the illustrated example, the contact location 28 is formed by an apex of the bottom surface 26 of the central balancing member 12. The central balancing member 12 is pivotable about the apex. In the illustrated example, the central balancing member 12 has a vertical cross-section that is triangular in shape.

A first pivot joint 30 connects the first foot pad 18 to the central balancing member 12 such that the first foot pad 18 is pivotable with respect to the central balancing member 12. A second pivot joint 32 connects the second foot pad 22 to the central balancing member 12 such that the second foot pad 22 is pivotable with respect to the central balancing member 12. The first and second pivot joints 30, 32 are configured such that the first and second foot pads 18, 22 are pivotable into and between a first position (see FIG. 2) wherein the first and second foot pads 18, 22 have top surfaces that are in parallel alignment with each other, and a second position (see FIG. 3) wherein the top surfaces of first and second foot pads 18, 22 are out of parallel alignment which each other. The first and second pivot joints 30, 32 are configured such that the first and second foot pads 18, 22 are pivotable out of the first position shown in FIG. 2 in only one direction. In other words, the configuration of the first and second pivot joints 30, 32 prevents pivoting motion of the first and second foot pads 18, 22 past parallel with each other (i.e. past the position shown in FIG. 2). The type and configuration of the first and second pivot joints 30, 32 can vary. In the illustrated example, the first and second pivot joints 30, 32 include hinges 34, 36. In the illustrated example, location of the first and second pivot joints 30, 32 at the top edges of the first and second foot pads 18, 22 prevents pivoting motion past parallel. That is, pivoting movement past parallel is prevented by engagement between the respective side surfaces 23, 25 of the first and second foot pads 18, 22 and the side surfaces 27, 29 of the central balancing member 12.

The configuration of the first and second foot pads 18, 22 and the central balancing member 12 can vary from that which is shown. In the illustrated example, the first and second foot pads 18, 22 have planar top surfaces 19, 21 that are in parallel alignment which each other when the balancing exercise device 10 is in the position shown in FIG. 2. The planar top surfaces 19, 21 are out of parallel alignment with each other when the balancing exercise device 10 is in the position shown in FIG. 3.

Referring to FIGS. 4 and 5, resilient members 38 span the coupling between the first and second foot pads 18, 22 and the central balancing member 12. The resilient members 38 are configured to bias (i.e. pull or push) the first and second foot pads 18, 22 towards the first position shown in FIG. 2. The configuration of the resilient members 38 can vary from that which is shown. FIG. 4 shows one example wherein the first and second resilient members 38 are tension springs having a first end 42 connected to the central balancing member 12 and a second end 44 connected to the central balancing member 12. In this example, the spring 40 tends to pull the respective foot pad 18, 22 towards the position wherein the top surfaces of the respective foot pads 18, 22 are in parallel alignment with each other (and in this example also with the top surface of the central balancing member 12). FIG. 5 depicts an alternate example wherein the springs 40 are torsion springs having first and second ends 42, 44 connected to the respective foot pad and central balancing member 12. Again, the springs 40 tend to pull the respective foot pad 18, 22 towards the position shown in FIG. 5.

The present disclosure thus provides a balancing exercise device 10 that is configured so that an application of equal downward forces by the user's feet 46, 48 on the first and second foot pads 18, 22 balances the central balancing member 12 with respect to the center of balance 16. As shown in FIG. 3, an application of unequal downward forces on the first and second foot pads 18, 22 causes the central balancing member 12 to pivot about the center of balance 16 (towards the side of the greater force) until the respective foot pad 18, 22 on the side of the greater force engages with the support surface 14. In the illustrated example, a relatively larger force is being applied on the first foot pad 18 than the second foot pad 22.

Each of the first and second foot pads 18, 22 have bottom surfaces 52 with inner and outer edges 54, 56. As the central balancing member 12 pivots about the center of balance 16, the outer edge 56 of the respective foot pad 18, 22 initially engages the support surface 14 before the inner edge 54 of the respective foot pad 18, 22.

Continued unequal application of the unequal downward forces ultimately results in engagement of the inner edge 54 of the bottom surface 52 with the support surface 14, such that continued pivoting of the central balancing member 12 about the center of balance 16 is prevented. Initial engagement of the outer edge 56 with the support surface 14 causes a pivoting motion to occur between the central balancing member 12 and the first foot pad 18. More specifically, when the outer edge 56 engages the support surface 14, the central balancing member 12 continues to pivot about the center of balance 16, while the first foot pad 18 begins to pivot about its outer edge 56. As this pivoting motion occurs, the second foot pad 22 is configured to remain in place (in the illustrated example it remains parallel with the top surface of the central balancing member 12).

These same pivoting movements occur when a relatively larger force is applied by the user's foot on the second food pad 22 rather than the first foot pad 18.

Through research and experimentation, the present inventors have endeavored to provide a balancing exercise device that allow a user to ergonomically shift their weight from one foot to the other, without requiring excessive balancing action, thus allowing the balancing exercise device to be used for extended periods of time. The inventors found that prior art rocking or balance boards lack suitable ergonomics, particularly with respect to the feet and ankles of the user. Advantageously, the balancing exercise devices 10 herein described promote better ergonomics while allowing the user to safely shift their weight to one side. As each respective foot pad contacts the support surface, it begins to rotate through a degree of motion with respect to the outer edge 56. In certain non-limiting examples, this degree of motion can be 10 degrees. This allows the respective foot pad to become nearly flat with the support surface 14 when the balancing exercise device 10 is in the position shown in FIG. 3. The resilient members 38 advantageously facilitate these movements and also provide a damper as the bottom of movement (i.e. the position shown in FIG. 3) is approached. This provides some assistance and/or rebound when the user shifts their weight back to the opposite side. This arrangement thus advantageously creates a smooth transition, limits uncomfortable impact, and minimizes balancing requirements of the user.

The dimensions of the balancing exercise device 10 can vary. In certain examples, the bottom edge of the central balancing member 12 has a radius of at least 4 inches and the vertical displacement of the user's feet when one is up and the other is down can be about 2.5 inches.

In the present description, certain terms have been used for brevity, clarity and understanding. No unnecessary limitations are to be inferred therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes only and are intended to be broadly construed.
