Abstract

PROBLEM TO BE SOLVED: To improve impact absorption ability by raising the three contact points of a transverse foot arch, an inner planter arch and an outer plantar arch with a sole higher than the other parts. SOLUTION: This sole 1 is formed from leather or rubber, etc., and is composed of high parts 1a, 1b and 1c and low parts 1d and 1e. Further, reinforcing plates 2a, 2b and 2c are fitted around the high parts. By forming the high parts 1a, 1b and 1c, the contact points of the three arches that are the inner plantar arch, the outer plantar arch and the transverse foot arch are supported and fixed. Also, since they are higher than the other parts, the contact points of the respective arches are independently moved. As a result, impact absorption by springs and stability at the time of walking are improved, resultant force received by the arches is transmitted to a lower leg bone and the muscle fatigue of a foot or the like is prevented. Further, by using the sole for the long period of time, the arches of the foot are strengthened and a flat foot and hallux evagination, etc., are prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention fixes the three parts of the heel, which is the contact point between the soles of the three arches that the foot originally has, and the upper and inner medial parts excluding the toes. The present invention relates to a shoe sole that reinforces and strengthens the impact absorption capability of a foot arch to enhance the function of the foot, and at the same time prevents foot fatigue and injury.

[0002]

2. Description of the Related Art Conventional soles are designed only to absorb the impact from the ground, and when the ground is hard, it is thicker and when soft, it is thinner, or the material of the sole is changed. Absent. However, there is no special shock-absorbing skin or tissue on the sole of the human foot, but three independently changing arches consisting of the bones and ligaments of the foot have the main shock-absorbing ability. . However, the function of this arch is not taken into consideration in the conventional shoe sole. Moreover, in the conventional shoe sole, when the shoe sole is soft, the arch sinks, and when the shoe sole is hard, the arch does not function independently, which rather lowers the shock absorbing ability and stability that the foot originally has. In addition, sprains are often created due to the weaker portion of the arch covering each tip.

[0003]

Considering the drawbacks of the conventional ones, the following problems can be considered. (A) Keep or emphasize the arch shape of the foot on the sole. (B) The contact point between the arch of the foot and the sole of the foot is fixed more firmly than the other parts, and it moves smoothly. (C) Prevent the arch of the foot from being deformed by the impact from the outside of the sole. An object of the present invention is to enhance the shock absorbing ability of the foot originally, and to reflect the function of the arch provided in the foot on the shoe sole.

[0004]

In reflecting the function of the arch of the foot on the sole, in order to maintain or reinforce the shape of the arch on the sole, three points of contact with the sole of the arch are provided. Harder or higher than other parts. Reinforcement plates were provided on the outside of the three ground points formed by the foot arch to prevent the arch from being deformed by impact pressure from the side.

[0005]

In the shoe sole according to the present invention, the impact transmitted from the sole of the foot is once received and absorbed by the entire sole of the shoe, and then transmitted to the respective arches from the contact points of the three arches, and is absorbed by the spring function of the arches. To be done. That is, as shown in FIG. 1, the foot has two springs, an inner longitudinal foot arch and an outer longitudinal foot arch, to absorb the shock generated when moving in the anteroposterior direction, and a lateral foot arch that absorbs the shock generated from the left and right shakes. There is. Impacts from weight and gravity are absorbed by these,
Furthermore, the resultant force received by each spring is transmitted to the lower end of the lower leg. Gravity is mainly applied to the lower leg bones, so that the muscles of the lower leg are prevented from fatigue during walking. The reinforcing plate made at the contact point of the arch protects the impact from the side of the foot and prevents sprains and stabilizes the foot. In addition, since the parts other than the contact points of the arch are relatively thin, soft, and flexible, the three contact points at the bottom of the arch can move independently, which provides stability even when walking on a bumpy road. be able to.

Embodiment 1 FIG. 2 is an embodiment of the shoe sole of the present invention. The figure (A) is a plan view, the figure (B) is a side view seen from the outside,
The same figure (C) is a side view seen from the inside. Reference numeral 1 denotes the entire shoe sole, which is made of natural leather or rubber or synthetic resin, leather or rubber, and is composed of high portions 1a, 1b, 1c and low portions 1d, 1e. It may also be covered with cloth, synthetic fibers or leather. 2 around the higher part
There are reinforcing plates a, b, c. The reinforcing plate is made of leather, rubber or synthetic resin. Next, the function will be described based on the above embodiment with reference to FIG. 1
By providing high parts of a, 1b, and 1c, it becomes possible to reinforce and strengthen the lateral arch 3a, the outer longitudinal arch 3b, and the inner longitudinal arch 3c, and the function of three springs as a shock absorbing function can be achieved. It can be fully demonstrated. That is, the three contact points of the arch of the foot are fixed, and the contact points are thin and flexible so that the tips of the arches move independently and are balanced and fixed. Furthermore, since the toes are low, the fingers can move easily and the functions of the three springs can be further stabilized.

In the shoe sole according to the present invention, the contact points of the three arches of the inner longitudinal foot arch, the outer longitudinal foot arch, and the lateral foot arch are supported and fixed, and the contact points of each arch are softer or higher than other parts. Can move independently. As a result, the function of the arch originally possessed by the foot can be fully exerted and enhanced. That is, the shock absorption by the spring and the stability during walking are enhanced, the resultant force received by the arch is transmitted to the lower leg bone, and muscle fatigue of the foot is prevented. Further, by using the shoe sole of the present invention for a long period of time, the arch of the foot is strengthened and flat feet and hallux valgus are prevented.
