Description

BACKGROUND OF THE INVENTION

The present invention relates to exercise equipment and, more particularly, to an exercise step that helps exercise the calf muscles and thigh muscles in a user's legs.

Many forms of exercise equipment exist in the fitness industry. However, most of these devices are complex and mechanical in nature (i.e., has moving parts), which often results in them requiring significant space for use and/or are cost-prohibitive for an average user to acquire. Consequently, the overwhelming majority of available exercise equipment is mechanical and exists only in gyms.

Because this type of equipment is largely left for gym use, users have no viable exercise options for at home, work, or other locations they frequent (besides the gym). No non-mechanical exercise leg equipment exists to specifically target the calf and thigh muscles.

As can be seen, there is a need for an apparatus and method for non-mechanically exercising calf and thigh muscles, as described herein.

SUMMARY OF THE INVENTION

In one aspect of the present invention, an exercise step configured for use with leg exercises is disclosed, and comprises: a main body comprising: a substantially planar and horizontally oriented upper wall configured to support a sole portion of a user foot; and a sloped wall extending from a bottommost surface of the exercise step to the upper wall, the sloped wall being configured to support a heel portion of the user foot.

In another aspect of the present invention, a method of exercising a user's legs is disclosed, with the method comprising the steps of: providing an exercise step comprising a main body, the main body comprising: a substantially planar and horizontally oriented upper wall; and a sloped wall extending from a bottommost surface of the exercise step to the upper wall; stepping on the sloped wall with a heel portion of a user foot; and raising the heel portion such that a sole portion of the user foot is supported by the upper wall.

These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Broadly, an embodiment of the present invention provides an exercise step including a main body that comprises: (1) a substantially planar and horizontally oriented upper wall that is configured to support a sole portion of a user foot; and (2) a sloped wall that extends from a bottommost surface of the exercise step to the upper wall, with the sloped wall being configured to support a heel portion of the user foot.

Making reference to FIGS. 1-4, an exercise step includes a main body 10. As shown, the main body 10 comprises a step portion 12 and a wedge portion 14 on an upper side thereof. As seen, for example, in FIG. 2, the step portion 12 is constituted by a substantially planar horizontal upper wall, and the wedge portion 14 is constituted by a sloped wall/surface extending downwardly from the step portion 12. As can be readily seen, the step portion 12 defines an uppermost surface of the exercise step and functions as a platform for a user 20 to step on during a portion of an exercise, as described in greater detail below. As shown, for example, in FIG. 4, the horizontal lengths (relative to FIG. 4) of the step portion 12 and the wedge portion 14 are approximately equal, resulting in a large foot sole landing area (the step portion 12), which will be described in greater detail with reference to FIGS. 5A-5C. As shown in FIGS. 3-4, the wedge portion 14 terminates at a bottommost surface of the main body, resulting in a smooth, continuous surface for users 20 to place the heels and middle portions of their feet in use, which will also be described in greater detail below.

As shown in FIG. 3, a band channel 16 is defined on a bottom side of the wedge 10, which allows an exercise cord 18 to pass under the main body 10 for optional use by the user 20. Further, a plurality of ribs are provided on the underside of the exercise step such that overall material may be reduced (as opposed to a solid block of material) while still providing a wedge 10 capable of withstanding large loads (e.g., various weights of users 20 as well as any additional exercise equipment, such as dumbbells, the users 20 may be holding).

FIGS. 5A-5C show one method of using the exercise step. First, a user 20 (by way of example, a male) places a heel on the wedge portion 14. Because the wedge portion 14 extends all the way to the ground, in use, the surface in which the user 20 places his heel is ensured to be smooth (i.e., the user 20 won't mistakenly step on any sharp edges). Gradually, the user 20 transfers his weight to the sole portion of his foot by raising his heel, as shown by the counterclockwise arrow in FIG. 5B. This movement results in the sole portion (which includes the toes) of his foot engaging the step portion 14, as shown in FIG. 5B. The step portion 14 is sized lengthwise such that any length foot can use this exercise step The user can then continue to raise his foot until he is standing on his toes, as shown in FIG. 5C. The user can then follow the reverse steps to lower his foot and may repeat in an up and down motion.

Users 20 can use either a single exercise step to exercise a single leg, or two exercise steps to exercise both legs simultaneously, the method of using both simultaneously following the same procedure as described. Further, a resistance band 18 that slides in the band channel 16 at the bottom of the main body 10 may be used to further exercise the calf muscles in combination with the steps described above, as demonstrated, in part, by FIGS. 6-7. Other exercises may be performed with the exercise step described herein, such as squats, to further exercise thigh muscles, in accordance with the present invention.

A method of making the present invention may include the following. For mass production, injection molding may be used to make the mold and wedge. A mold (such as a steel injection mold) is formed with, for example, a computerized numerical control (CNC) machine. Plastic granules are heated and injected into the steel mold to form a single piece plastic wedge. While other fabrication techniques may be employed, others, such as three-dimensional printing, are unsatisfactory because wedges made by that process would not be of sufficient strength to withstand the weight of an average human body.

In certain embodiments, the exercise step may consist essentially of the structure described and shown herein. Advantageously, and as mentioned above, embodiments of the present invention are single piece exercise blocks, which simplify the manufacturing process thereof and result in lower material and production costs. Thus, an end user 20 can perform various calf and thigh exercises without the need for expensive, mechanical equipment or a trip to the gym.

In summary, an embodiment of the present invention is a light, portable piece of exercise equipment specialized to work out the calf/thigh muscles. As discussed above, prior to the present invention, there were no at-home non-mechanical exercise equipment available that concentrate on working out the calf/thigh muscles. Embodiments of the present invention are non-mechanical (so there's no need to worry about a moving part breaking), lightweight, affordable, easy to use, and users can use their own weight(s) and/or resistance bands to work out their leg muscles.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.

In the following claims, any labelling of elements, limitations, steps, or other parts of a claim (for example, first, second, etc., (a), (b), (c), etc., or (i), (ii), (iii), etc.) is only for purposes of clarity, and are not to be interpreted as suggesting any sort of ordering or precedence of the claim parts so labelled. If any such ordering or precedence is intended, it will be explicitly recited in the claim or, in some instances, it will be implicit or inherent based on the specific content of the claim. To further aid the USPTO and any readers of any patent issued on this application, it is additionally noted that there is no intent any of the appended claims to invoke paragraph (f) of 35 U.S.C. § 112 as it exists on the date of filing hereof unless the words “means for” or “step for” are explicitly used in the particular claim.
