Description

RELATED APPLICATIONS

This application is a reissue application of U.S. Pat. No. 10,843,039 B2, issued from U.S. patent application Ser. No. 16/161,132, filed on Oct. 16, 2018, the contents of which is hereby incorporated by reference.

TECHNICAL FIELD

The embodiments relate to an exercise apparatus, and more particularly relate to an exercise apparatus for the strengthening and rehabilitation of the muscles, tendons, and joints, of the lower extremities in addition to improving gait.

BACKGROUND

Exercise boards employing various means for creating instability have been used to promote workout intensity and improve balance. Increasing muscle activity through the use of various exercise routines has been effective in promoting a healthy anatomy, and improving physical performance.

Current methods and devices suffer substantial drawbacks. Many balance boards include a single platform upon which the user stands, allowing the user to use the entirety of both feet and their body to properly balance. These devices do not focus on the various muscles of the feet and toes which are considered crucial in proper balance and gait mechanics. While performing the balancing exercise barefoot may require more muscle recruitment from the feet and toes, these devices do not isolate the hallux (“big toe”) as the primary driver of propulsive force during gait.

In some circumstances, isolation of each foot can be beneficial in developing the muscles each foot. The current devices do not provide a method for isolating each foot to promote the balanced utilization of the muscles required for proper gait.

Embodiments presented herein relate to an exercise apparatus to strengthen and rehabilitate muscle groups related to proper balance and gait of a human user. FIG. 1 shows the first rocker board 110 and second rocker board 120. It is understood by one skilled in the arts that each of the first and second rocker board 110,120 can be non-superimposable mirrored structures of one another to facilitate the human anatomy of the feet and toes. The top surfaces 210,220 are each dimensioned to support the right and left feet of the user such that the first rocker board 110 supports the left foot, and the second rocker board 120 supports the right foot. In some embodiments, a left indicator 130 and right indicator 132 are provided to identify proper foot placement to ensure a suitable central axis 140 is provided. The apertures 160 is positioned at a suitable angle 150 which is about 45° from the central axis 140. In some embodiments, the suitable angle 150 can include angles between 35° and 55° from the central axis 140 such that the angle 150 corresponds to the anatomical axis of pronation and supination of the foot.

The first and second rocker boards 110,120 are designed to support the weight of a person in many different positions, including standing and squatting positions in addition to any movement in common balancing muscle strengthening exercises. Each of the first and second rocker boards 110,120 are suitably dimensioned to support a foot and rays of the user such that no portion of the foot or rays is extending past the perimeter of the rocker boards 110,120. Suitable materials include wood, metals, and substantially rigid plastic materials.

In some embodiments, each rocker board 110,120 is substantially planar to provide a suitable surface for standing, balancing, or exercising. FIG. 2 illustrates a plurality of convex rockers 200 engaged with one of the apertures 160 such that the convex rockers 200 protrude from the bottom surface 230,240 of the rocker boards 110,120. Auxiliary convex rockers (not shown) can be provided and releasably engaged with apertures 160 similarly as described above. During use, the user stands upon the top surface 210,220 of each rocker board 110,120. In some embodiments, two convex rockers 200 are positioned in parallel to protrude from the bottom surfaces of each rocker board 110,120. The two convex rockers 200 on a rocker board (such as 110) are herein referred to as a “set”.

In some embodiments, a single convex rocker 200 is engaged with one or more apertures 160. The single convex rocker 200 can be constructed to support the user during an exercise routine.

Referring back to FIG. 1, one skilled in the arts will understand that the convex rockers 200 can be positioned at any combination of apertures 160 to provide additional exercise routines and altered muscle stimulation.

Convex rockers 200 may be provided as one of a set or kit to provide alternate angles of deflection and increased balancing difficulty. The convex surface 250 on the rocker plates defines the rate of change of the angle of deflection of the board. The board may be deflected as much as perpendicular, i.e., 45°, to the ground, but for most embodiments, the maximum angle of deflection of the board is between 10° and 35°. In a preferred embodiment, the maximum angle of deflection is between 12° and 16°. The user may increase the difficulty by using convex rockers having a more sharply curved convex surface. Each convex rocker 200 may be shaped as a semi-circle, semi-sphere, or semi-ovoid member. In an alternate embodiment, each convex rocker 200 is pivotally engaged with one or more apertures 160 to provide varying planes of deflection during exercise.

FIG. 3 shows the apparatus 10 having a base 355,365 configured to lie atop a substantially flat surface 350,360. Each platform 310,320 is positioned between the corresponding base 355,365 and the rocker board 110,120. Each platform includes sets of recessed channels 330 dimensioned to receive and retain the convex rockers 200 and rocker boards 110,120 connected thereto. The convex rockers 200 each include a mounting portion 340 which is insertable into an aperture 160 to retain the convex rockers 200 at the bottom surfaces 230,240 of each rocker board 110,120.

The apparatus 10 can be configured to exercise with a single foot (left or right) of the user, or as a set such that both the left and right feet of the user are exercised. The embodiment illustrated in FIG. 3 can be otherwise shown wherein bases 355,365 are configured as a single connected component. Further, platforms 310,320 may also be configured as a single connected component.

It will be understood by one skilled in the art that a variety of instability members (illustrated as convex rockers 200) can be utilized to promote the strengthening of the anatomy and a proper gait. Instability members can include the convex rockers 200 shown, in addition to one or more balance domes, one or more rollers, or other suitable instability members.

FIG. 4 illustrates a foot (shown as the user's left foot) 400 having the first ray (i.e., big toe) 405 contacting the top surface 210 of the first rocker board 110. The second, third, fourth, and fifth rays (herein referred collectively as 407) are positioned at a cutout 410 to isolate the second, third, fourth, and fifth rays 407 from contacting the top surface 210 of the first rocker board 110. The cutout 410 is provided through the entire thickness of the first rocker board 110 such that the first, second, third, and fourth and fifth rays 407 are unable to sufficiently contact a surface to provide a balancing force. The first ray 405 resides on the top surface 210 to provide sufficient force to balance the user atop the rocker board 110 during use.

One skilled in the arts will understand that FIG. 4 as shown and described can be readily implemented with the user's right foot and corresponding second rocker board 120. Further, each rocker board 110,120 can be turned upside down to exercise either foot. For example, the first rocker board 110 can first be used to exercise the left foot by positioning the of convex rockers 200 on the bottom surface 230 and placing the foot on the top surface 210. The right foot can be exercised by removing the convex rockers 200 from the bottom surface 230 and engaging the convex rockers 200 with the top surface 210, while the right foot contacts the bottom surface 230 of the first rocker board 110.

Now referring to FIG. 5, a user 500 is shown balancing atop each rocker board 110,120. In some embodiments, two convex rockers 200 (i.e., a set) are positioned in parallel to releasably engage with the first rocker board 110, while two convex rockers 200 (i.e., a second set) are positioned on the second rocker board 120 such that the convex rockers 200 on the first rocker board 110 are perpendicular to the convex rockers 200 on the second rocker board 120. The user 500 can then stand and balance on the rocker boards 110,120 while positioning the first ray 405 having sufficient contact with the top surfaces 210,220 and isolating the second, third, fourth, and fifth rays 407 over or partially through the respective cutout 410.

FIG. 6 shows the user 500 standing upon the first rocker board 110. An auxiliary exercise device 600 is shown mounted to an aperture 160 of the rocker board 120. In the illustrated embodiment, the auxiliary exercise device 600 is a resistance band fastened to the aperture 160 by looping and tying the exercise band through the aperture 160. The exercise band is pulled by the hand of the user to impart an unstable force to the rocker board 120. The first ray and foot forcefully balance the user 500 while the second, third, fourth, and fifth rays of the user 500 are isolated by the cutout 410.

Intrinsic and extrinsic muscles are strengthened as the user 500 engaged in various exercises while using the apparatus 10. The user 500 utilizes the intrinsic and extrinsic muscles in communication with the leg, foot, and first rays to manipulate and stabilize each rocker board 110,120 during an exercise.

The apparatus 10 allows for users having differing levels of capabilities by providing interchangeable and modular components as part of a set. In one example, the degree of difficulty in balancing on one or more of the rocker boards 110,120 throughout an exercise by providing a numbering of different convex rockers 200 having varying shape, size, and radius of curvature. In one example, the diameter of each convex rocker 200 and height of each convex rocker 200 may vary between sets of predetermined ranges.

One skilled in the arts will recognize various exercise positions, protocols, and techniques that will be useful with the apparatus 10. The exercise may not be limited to standing positions, as sitting techniques can be useful, especially in compromised or otherwise rehabilitating users.

To provide suitable top surfaces 210,220 a cover may be provided having favorable grip, feel, softness, tack, or texture to ensure comfort and adequate friction between the foot of the user and the rocker boards 110,120.

From the foregoing, it will be appreciated that the present invention provides a versatile exercise apparatus having a platform for exercising to which different forms and shapes of instability members and exercise attachments may be detachably mounted so that the person using the apparatus may perform a wide variety of exercises in a number of different exercise positions on the platform.

The exercises may be performed on the platform either with or without weights, exercise attachments on the top surface of the platform or other external exercise devices including but not limited to exercise bands, medicine balls, and weights.
