Foot training equipment

Abstract

This product provides a foot training device that solves the problems of conventional semi-cylindrical and spherical types and improves the kinetic chain of the entire body. [Solution] The ratio of the maximum width (W2) and overall height (H1) is set to approximately 1:1.232:0.654, based on the width of the base (W1). This unique ratio is optimized to be based on the length of the cuboid bone, without physically restricting the kinetic chain like conventional semi-cylindrical types, and without causing defensive postures due to pain or fear like spherical types. This high level of stability and relaxation facilitates rotational movements on the device, inducing a kinetic chain from the feet to the spine and solidifying the training effect.

Description

Technical Field

[0001] The present invention relates to a foot training device that is placed on the floor surface for a user to ride thereon and perform training such as stepping motions and single-leg standing, so as to improve a whole-body movement chain that is linked from the foot to the hip joint and spine along with stimulation to the sole of the foot.

Background Art

[0002] Conventionally, as tools for the purpose of forming an arch on the sole of the foot, semi-cylindrical (kamaboko-shaped) tools and spherical or protruding tools are known.

[0003] However, although the semi-cylindrical tool has an appropriate impact on the foot, the contact surface (bottom width) with the floor surface is too wide, so the effect of pushing up the cuboid bone pinpointedly is low. Furthermore, due to the wide compression surface of the bottom, there is a problem that the rotational movement of the hip joint and spine during single-leg standing (hereinafter, movement chain) is physically hindered.

[0004] On the other hand, although the spherical or protruding tool has a high effect of lifting the cuboid bone, the stimulation to the sole of the foot is too strong, resulting in pain, and it is often difficult to continuously implement. In addition, there is a problem that an "defensive posture (muscle tension)" due to excessive pain stimulation or an unstable high feeling occurs, and as a result, the whole-body movement chain is hindered.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention has been made to solve the problems of the prior art as described above, and aims to provide a unique dimensional ratio that optimizes the load on the sole of the foot, suppresses physical and psychological defensive reactions, and does not hinder rotational movement. Thereby, it is an object to provide a foot training device that can not only align the skeleton of the sole of the foot but also dramatically improve the whole-body movement chain during single-leg standing.

Means for Solving the Problems

[0006] The foot training device according to the present invention comprises a curved upper surface that contacts the sole of the user's foot and a bottom surface that contacts the floor, with an overall height (H1) in the range of 15 mm to 20 mm, a bottom surface width (W1) in the range of 25 mm to 32 mm, and a maximum width (W2) of the main body that is wider than the bottom surface.

[0007] The most distinctive feature is that, with the width of the base surface (W1) set as the baseline "1", the dimensional ratio of each part is approximately W1:W2:H1 = 1:1.232:0.654. ​​This ratio is based on W1, which conforms to the anatomical size of the cuboid bone, while also incorporating a design that widens the contact area to prevent defensive reactions due to load-bearing pain (W2), and a height design that eliminates fear (H1). This high level of stability and maintenance of a relaxed state enables smooth rotational movement on the device. [Effects of the Invention]

[0008] According to this invention, unlike conventional semi-cylindrical types, the kinetic chain is not physically restricted, nor does it cause defensive postures due to pain, as does the spherical type. Due to its unique dimensional ratio, the user can stand stably on one leg in a relaxed state, so that the correct kinetic chain (rotational movement) is naturally induced, starting from the precisely pushed-up cuboid bone and extending from the lower limbs to the spine.

[0009] As a result, it not only corrects the foot itself, but also improves the overall balance function and kinetic chain of the body, and the effects can be sustained for a long period of time. Furthermore, because the ratio is based on W1, scaling to suit body size and expansion to other products is also easy. [Brief explanation of the drawing]

[Figure 3] This is a bottom view of the device. [Figure 4] This is a perspective view of the device. [Figure 5] This is a perspective view showing the device in its disassembled state. [Modes for carrying out the invention]

[0011] The embodiments of the present invention will now be described with reference to the drawings. Figures 1 to 4 show the overall configuration of the foot training device of the present invention, and Figure 5 shows its disassembled state.

[0012] The device of this invention is a long, slender, columnar (semi-circular) member having a flat bottom surface that contacts the floor and a curved upper surface that contacts the soles of the user's feet. The main body can be divided into two members in the middle of its longitudinal direction (see Figure 5), and a joint structure with protrusions and recesses is provided at the joining part.

[0013] As an extremely important component of this invention, as shown in Figures 1 to 3, the overall height (H1), the width of the base (W1), and the maximum width of the main body, which is the most bulging part of the curved surface (W2), are configured in a unique dimensional ratio of approximately W1:W2:H1 = 1:1.232:0.654, based on the width of the base (W1).

[0014] In the dimensional design of this invention, the unique bulging shape, in which the maximum width (W2) is wider than the base (W1), achieves both "ground contact stability" and "pain reduction through load distribution," which were not possible with conventional semi-cylindrical shapes. Furthermore, the design with a reduced height (H1) eliminates the fear of heights and allows the brain to perceive it as safe, thereby releasing defensive reactions.

[0015] In this relaxed state, free from defensive reactions, the cuboid bone is elevated, enabling a smooth rotational movement in single-leg standing, which was physically impossible with conventional tools that have excessively wide bases. This rotation triggers a correct kinetic chain from the hip joint to the spine, resulting in improved functional posture throughout the entire body. [Explanation of Symbols]
