Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a shoe sole,
More specifically, when worn, the soles of the feet are always fitted to the ground, and no excessive force is applied to the feet, making it easy and comfortable to stand or sit in a chair. In addition, when walking or running, the "inclined plate effect" is a health device with a raised toe that stretches the back of the body, such as Ken Achilles and the biceps femoris, and tightens the lower body without being conscious. The “high heel effect,” which stretches the front of the body such as the tibialis anterior and quadriceps, tightens the lower body and raises the hips. "Aotake stepping effect" of acupressure and balance feeling of the sole is obtained. In this way, by stretching the whole body, shape up, strength training,
The present invention relates to a shoe sole suitable as a sole structure of a shoe sole from the viewpoints of human aspects of beauty, health and safety and functional aspects of the shoe.

[0002]

2. Description of the Related Art Conventional shoe bottoms are generally concave and flat with a toe and a heel protruding, and an arched part being dented.
Heelless shoes that cut the heel for the purpose of stretching, muscular training and posture correction, or consist of three surfaces: heel, center of sole, and toe. Some shoe bottoms are fitted with semi-cylindrical or semi-spherical projections. In these prior arts, the shoe sole shape surface is suitable for each operation purpose such as stretching and training, but when viewed comprehensively from walking engineering, the shoe sole surface does not match the foot.

[0003]

A shoe sole suitable for a foot in terms of gait engineering always receives a force on the entire back of the foot against the movement of the leg in order to reduce the burden on the foot when worn.
The angle of the tibia changes well back and forth at the malleolus to stretch and tighten the body. Stimulates the soles of the feet moderately to prevent fatigue and activate the internal organs. A shoe sole structure that satisfies this condition requires a convex shape consisting of two surfaces, a front inclined surface and a rear inclined surface. If it is a multi-sided or arcuate surface with three or more sides, it will be "tilting walking" and the stretching effect will be reduced.

However, since the above-mentioned shoe sole having a concave shape and a flat shape does not have a convex inclined surface, as shown in FIG. Department,
Further, when kicking, the force is concentrated on the toe as shown in FIG. Furthermore, immediately after landing, the shoes become horizontal, and immediately before kicking, the heels rise immediately.
As shown in (b) and (c), the tibial angle θ of the tibia K is about 90 degrees and hardly changes, and the angle change is small. further,
In the case of a concave shoe sole, when stepping on, the arch of the metatarsal and the arch of the shoe become double arches, the weight is concentrated on the toes and the heel, the arch is not stimulated, and the tire is easily fatigued. Therefore, stimulation such as stepping on green bamboo is required.

Heelless shoes in which the heel portion of the sole is cut have a rear slope, so that the load on the foot when landing is small and the safety is increased. Further, the angle of the anterior inclination of the tibia is changed by the posterior inclined surface, and there is an inclined plate effect. However, when kicking, since there is no anterior inclined surface, force concentrates on the toe and the burden on the foot is large, and there is no angle change to the rear side of the tibia, so that the high heel effect does not occur. In addition, heels, the center of the sole, Heales shoes consisting of three sides of the toe landing on the heel side,
The kick on the toe surface and the "footed walking" reduce the burden on the foot. However, since there is a surface in the center of the sole, the angle change of the tibia is small, and the effect of the inclined plate, the effect of the high heel, and the effect of stepping on the green bamboo are small. In addition, you must walk consciously, and if you are not used to it, you will not be able to jockey and you will need continuous will.

[0006] A shoe with a convex attached to a part of the sole is effective for stimulating the sole of the foot, but when landing and kicking, it is not a surface contact with the ground but a two-point partial contact. It is very expensive and unstable. If the rigidity of the sole is not increased, the convexity is elastically absorbed and the effect of the inclined plate and the effect of the high heel are reduced. The present invention eliminates these drawbacks, enjoyable and comfortable stretching in everyday natural life,
An object of the present invention is to provide a shoe sole that can be used as a structure on a bottom surface of the shoe, which can be shaped and trained to promote beauty and health.

[0007]

In order to achieve the above object, the sole of the shoe according to the first aspect of the present invention is provided at the bottom of the sole body of the shoe from the tip of the toe to the heel side and to the heel side. From the rear end to the toe side, the sole is thickened at an inclination angle of 5 to 50 degrees with respect to the sole body, and the intersection where the intersection is the thickest is the front slope and the rear slope. In the case of two surfaces, the side surface is V-shaped, or when the front inclined surface and the rear inclined surface have different inclination angles, the V-shaped convex shape is formed in an eccentric shape. It should be noted that a V-shaped vertex may be rounded with an arc having a radius of 2 cm or less.

[0008] The sole of the shoe according to the second aspect of the present invention, in the first aspect of the present invention, is provided with a plurality of anti-slip projections on the front inclined surface to prevent slipping backward. Also, a plurality of anti-slip projections are provided on the rear inclined surface to prevent slippage in the forward direction.

According to a third aspect of the present invention, in the shoe sole according to the first aspect of the present invention, the front inclined surface has abrasion resistance of metal or the like, and prevents teeth from slipping on snow, ice and soil. And a plurality of protrusions such as nails.

According to a fourth aspect of the present invention, in the shoe sole according to the first aspect of the present invention, the front inclined surface is provided with a plurality of anti-slip projections for preventing rearward sliding, and the rear inclined surface is mounted on snow. Treated with a material that slips well or stuck a ski plate.

The sole of the shoe according to the fifth aspect of the present invention is the shoe according to the first aspect, wherein the thickest portion of the convex shape of the V-shape or the irregular V-shape has a width of 2 cm to 5 cm and the front slope. Separated from the plane and the rear inclined plane.

In the sole of the shoe according to the sixth aspect of the present invention, a roller having a diameter of 50 mm or less is attached to the thickest portion of the V-shaped convex shape in the first aspect of the present invention.

According to the seventh aspect of the present invention, the shoe sole according to the first, second, third, fourth and fifth aspects has a V-shaped convex shape from the shoe sole body. The shoe sole is designed to be detachable and removable.

[0014]

[Function] By making the sole shape V-shaped, consisting of two front slopes and a rear slope, it becomes a landing base using the rear slope when landing, and the front slope when kicking. Because it is used as a kickstand, the burden on the legs and waist is small, and it is easy to stand on.

On average, the landing angle of the leg at the time of walking is 60 degrees with respect to the ground, and the kick angle is 120 degrees. With the two-sided shoe sole shape of the present invention, the foot is fixed at the rear inclined plane angle from 60 degrees to 90 degrees after landing on the rear inclined plane. Also, the foot is fixed at the angle of the front slope from 90 degrees to 120 degrees to kick on the front slope. As a result, the tibia has an angle change of ± 30 degrees on the posterior inclined plane and ± 30 degrees on the anterior inclined plane in a single walking motion, for a total of 120 degrees.

Further, during the change from the rear inclined surface to the front inclined surface, the bottom of the foot, particularly the arch, is stimulated at the apex of the V-shaped sole.

As described above, according to the shoe sole of the present invention, the burden on the legs and hips is small due to surface landing and kicking, and a continuous angle change of the tibia can be obtained, so that stretching, shape-up, training, There is acupressure.
