The present invention is in the field of athletic training devices, particularly balance training devices.
In addition to its benefits for overall health and injury prevention, ability to balance is essential to many athletic endeavors. Some activities, such as gymnastics and cheerleading, additionally require participants to maintain balance at a significant elevation above the ground or floor. Loss of balance during such activities is of course particularly hazardous. Cheerleading and other group performance activities may also include the complication that a participant must balance on the relatively irregular surface of a human hand (or pair of hands), shoulder, or other body part (such as an arm, leg, or back). To reduce the hazards associated with training and performance of elevated maneuvers in group performance activities, a training aid providing practice balancing on a relatively unstable surface at a reduced elevation would be desirable.
The problems described above are substantially solved by a portable device and a method allowing users to practice various strength and balance exercises. The portable device is an apparatus for standing upon using one or both feet. In a preferred embodiment, the apparatus comprises a platform with keyholes which accept a variety of inserts with different functions. On top of each insert, as well as the high point of the platform, is a pad of varying shape to provide instability.
In an embodiment, an apparatus for balance training of a user includes a pedestal dimensioned to underlie a portion of, but less than the entirety of, a foot of the user. An upper surface of the pedestal includes multiple protuberances positioned at or near the periphery of the upper surface and a comparatively lower region between the protuberances and at or near the center of the upper surface. In a further embodiment the upper surface of the pedestal may include four protuberances. Alternatively, the upper surface may include two protuberances. In a preferred embodiment, a height of the pedestal when in use is sufficient to prevent portions of the user's foot not in contact with the pedestal from contacting any surface underlying the pedestal. The pedestal may also be referred to herein as an “insert.”
The pedestal may include an upper portion having the upper surface described above and a lower portion supporting the upper portion during use. In an embodiment, the upper portion is formed from a material providing compressibility perceptible to the user. The upper portion may also be referred to herein as a “pad.”
The apparatus for balance training may also include a portable base unit dimensioned to underlie an entirety of the foot of the user. The base unit may also be referred to herein as a “platform.” In an embodiment, the lower portion of the pedestal is integral to the base unit. In an alternative embodiment, the lower portion of the pedestal is configured to removably connect to the base unit.
In an embodiment with the lower portion of the pedestal configured to removably connect to the base unit, the base unit may include a slot formed in an upper surface, and the lower portion of the pedestal may include a peg dimensioned to fit into the slot. Such a slot may also be referred to herein as a “keyhole,” and the peg may also be referred to as a “post.” The slot may have a varying width along its length, and the peg on the pedestal may be dimensioned to fit into one or more substantially fixed positions along the length of the slot. In an embodiment, the peg and slot described above may further be dimensioned to allow the pedestal to rotate about a substantially fixed position along the length of the slot.
In addition to a base unit and pedestal, an embodiment of the apparatus may include one or more additional pedestals configured to removably connect to the base unit. The base unit may be configured to support two or more pedestals simultaneously. The two or more pedestals supported by the base unit may be of different heights, and the upper surfaces of the pedestals may include different numbers of protuberances.
In addition to the apparatus described above, a method of balance training is contemplated herein. In an embodiment, the method includes removably connecting a pedestal to a base unit and standing upon an upper surface of the pedestal. The pedestal is dimensioned to underlie a portion of, but less than the entirety of, a foot of the user. An upper surface of the pedestal includes multiple protuberances positioned at or near the periphery of the upper surface and a comparatively lower region between the protuberances and near the center of the upper surface. The base unit is dimensioned to underlie an entirety of the foot of the user.
The method may further include adjusting a position of the pedestal in connection with the base unit. In addition, the method may include removably connecting different pedestals to the base unit to provide varying degrees of instability.
Further aspects of the invention will become apparent from consideration of the drawings and the ensuing description of preferred embodiments of the invention. A person skilled in the art will realize that other embodiments of the invention are possible and that the details of the invention can be modified in a number of respects, all without departing from the inventive concept. Thus, the following drawings and description are to be regarded as illustrative in nature and not restrictive.
The features of the invention will be better understood by reference to the following detailed description and the accompanying drawings in which:

Many variations of the invention will occur to those skilled in the art. For example, inserts or pedestals such as inserts 18, 23, 27, and 31 shown in the figures could be formed as a single piece rather than with separate upper and lower portions. Some variations call for platform 13 being different shapes and styles including different permanent high and low points, a surface with only keyholes 15 for inserts 18, 23, 27, 31 and non-flat bottom surfaces to allow instability. Other variations call for platform 13 to be formed from two or more parts to vary height and ease portability. Other variations include the entire device moving, shaking or raising and lowering by mechanical and electrical means. Other variations include larger and smaller versions, with varying densities of materials and shapes for the pads 14, 21, 25, 29, 33. Still other variations include additional inserts of varying size and shape for different balancing objectives. Other variations include different adjustment methods, sliding or rotating inserts and shapes of the keyholes 15. Other variations call for LED or other forms of lights, pressure point sensors, digital displays, audio speakers, microphones with voice recognition, data entry points, pliable and or traction material on the bottom surface and straps or connections to attach the device to ones feet.
Although the present embodiment is shown to include certain features, the applicants specifically contemplate that any feature disclosed herein may be used together or in combination with any other feature on any embodiment of the invention. It is also contemplated that any feature may be specifically excluded from any embodiment of the invention.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment and examples herein. The invention should therefore not be limited by the above described embodiment and examples, but by all embodiments and methods within the scope and spirit of the invention.
This application claims the benefit of U.S. Provisional Application No. 61/517,995 filed on Apr. 29, 2011.
