Description

Shoe sole {THE SOLE OF SHOE}

The present invention relates to a shoe sole, and more particularly, to be used in functional shoes, while walking like so-called masai walking, while avoiding a shape in which the central portion of the sole protrudes downward, to provide a shoe having a stable structure. The present invention relates to a shoe sole capable of evenly distributing the load on the body and exerting the effect of acupressure.

Due to rapid social development, as the indoor life increases, obesity and various adult diseases increase due to various types of disease factors that result from the decrease of the physical activity of the body and from the diversified and complex social structures. Recognizing these problems, in recent years, there has been a lot of interest in health following the well-being craze, which is a measure of happiness, a balanced life that can maintain a healthy body and spirit, rather than a life that seeks only material values or honor. The trend is losing.

In addition, it is well known that incorrect walking may adversely affect the joints and muscles, which may damage the overall health of the body, thereby increasing interest in walking and foot health, and improving walking or reducing foot fatigue. Functional shoes come up.

Shoes are worn to protect a person's feet. Shoes are usually divided into an upper portion protecting the instep and the ankle portion, and a sole portion configured to simultaneously act as a cushion while protecting the sole and increasing friction with the ground.

First of all, the upper part is also called the outer skin, and it is a part that greatly affects the health of the foot by promoting a comfortable fit and blood circulation using leather and the like.

The sole of the shoe is formed of a unitary structure that is integrally formed and divided into several layers such as an outsole (sole, outsole), a midsole (midsole, midsole), an insole (insole, insole). The present invention corresponds to the latter case, hereinafter will be described with respect to the shoe sole consisting of several layers, such as the latter.

The outsole corresponds to the bottom of the shoe, and refers to the part contacting the ground itself. The outsole is made of a high-strength wear-resistant natural rubber window, and has a different shape depending on the purpose of use such as anti-slip.

The midsole is the part formed between the outsole and the insole, which is formed using a variety of different materials for shock absorption and natural walking.

The insole is a part that sits on the midsole and is also commonly called an insole, which is separate and fixed.

In recent years, there is an increasing demand for shoes that can not only protect a person's feet when walking, but also allow masai walking, which can help health.

Masai walking is the correct walking posture that is formed when the Maasai, who have lived through hunting and grazing without walking, naturally walk barefoot on the soft grassland.

Unlike Masai walking, when walking with ordinary modern shoes, it is common to use only the heel and heel to walk, and when walking on hard soles such as asphalt and cement, the center of gravity is It can not be loaded in the center of the foot, and this causes the walking posture to be distorted and deformed without absorbing the shock from the ground, which adversely affects the joints or the spine, thereby adversely affecting the physical health.

On the other hand, the Maasai walk in the center of the foot where the entire sole of the foot touches the ground, and when they walk, they start to touch from the outside of the heel so that the center of gravity moves through the outside of the foot in the order of the little toe and the big toe. Fatigue is less than walking, so it is advantageous to walk long.

In addition, as the theory that the condition of the human foot has a great effect on health has emerged, interest in the protection and management of the foot is gradually spreading. According to this, according to the presence of the foot connected to correspond to each organ of the whole body on the sole as a miniature plate of the human body, by appropriately stimulating the area, it is possible to maintain the health by activating the overall system function of the human body, There is also increasing interest in shoes having acupressure function.

Korean Patent No. 10-0377822 discloses an active walking shoe in which the sole bottom surface of the shoe forms an arc.

Korean Patent Registration No. 10-0377822 introduces a shoe structure for actively walking and forcing to walk, but includes several problems as follows.

First, it has only a structure that enables active walking, the effect of acupressure on the foot cannot be expected, it cannot provide a visually and structurally stable form of shoes, and it can cause a disgusting appearance by abnormally thick soles.

Second, active walking begins with the heel landing on the ground, where the shock cannot be effectively absorbed.

Third, active walking is possible naturally in the front and rear directions when walking, but there is a problem in that when the external force in the left and right directions is not prevented from twisting or tilting, the circular restoration is not easily performed.

The present invention has been made to solve the problems described above, one embodiment of the present invention is used in functional shoes, such as the so-called Masai wicking continuous landing and load transfer from the heel to the heel during walking It is possible to provide a shoe sole that is structurally stable and capable of minimizing wearer fatigue by the acupressure effect.

One preferred embodiment of the present invention is a midsole binder located inside the sole; A front outsole coupled to the front of the bottom surface of the midsole binder and formed in an arc shape; A rear outsole coupled to the rear surface of the midsole assembly and formed in an arc shape; And a coupling body coupled to the center of the bottom surface of the midsole coupling body, both ends of which are positioned on the upper side of the front outsole and the rear outsole, and the central portion of which is convex upward.

According to an embodiment of the present invention as described above, first, the outsole is divided into a front outsole and a rear outsole, and each outsole is formed to form an arc so that masai walking is possible, and the ground at both points of the front outsole and the rear outsole It can get in contact with, improving stability.

Second, the convexly formed upper convex body is supported by the front outsole and the rear outsole underneath and is loaded so that pressure can be evenly applied to the entire foot from the heel to the heel while walking, and natural rolling is achieved. Can be.

Third, the connecting body is made to have a greater hardness than the midsole coupling body, the front outsole and the rear outsole, so that even when the front outsole and the rear outsole divided into two can prevent the excessive bending or twisting of the shoe when walking.

Fourth, the upper surface of the midsole assembly to form a gentle curved surface than the lower surface, sufficient buffer effect can occur in the front heel and heel.

Fifth, the midsole binder is composed of a soft thick first midsole and a hard thin second midsole, so that a sufficient cushioning effect occurs and a natural rolling is caused by the elastic action of the second midsole when the center of gravity moves from the heel to the center. rolling may be made.

Sixth, the midsole binder is divided into three parts, the upper midsole, the middle midsole and the lower midsole, and the hardness is made in the order of the lower midsole, the upper midsole, and the middle midsole, so that the soft buffer can be made inside the midsole. Improves comfort.

Seventh, the acupressure effect due to rolling can be improved by integrally forming the hard second midsole and the soft first midsole in which the acupressure protrusions are formed to form the central midsole.

It is done by

In addition, in the shoe sole 1 according to the preferred embodiment of the present invention, the connecting body 400, in the process of moving the center of gravity of the wearer when walking from the rear outsole 300 to the front outsole 200 When a load is applied to one side of the connecting member 400, the central portion is formed so as not to be lower than both ends.

The shoe sole 1 according to the present invention is not applicable to ordinary general shoes, but is preferably applied to walking shoes such as masai walking.

Masai walking, as described above, refers to a walking method, such as the Masai gait of Kenya, Africa. When walking, sequential movement of the center of gravity is performed from the heel to the toe, and the shock is alleviated. And a walking method to be dispersed.

That is, the shoe sole 1 according to the present invention, when walking with the shoe equipped with the present invention, the entire sole of the foot from the heel to the heel from when the shoes start to reach the ground to fall off the ground, The center of gravity is made to move continuously.

The midsole coupling body 100 is provided in the shoe sole 1 according to the present invention, and constitutes a central portion in the shoe sole 1.

The midsole assembly 100 occupies a substantial portion in the shoe sole 1 of the present invention, and is formed relatively thick to relieve the impact when walking. A detailed description thereof will be described later.

The front outsole 200 is coupled to the front of the bottom surface of the midsole combiner 100, and constitutes a part of the bottom surface of the shoe. The front outsole 200 is formed in an arc shape (弧形) is made of a round shape of the bottom surface, it is made so that only a relatively small portion is in contact with the ground. However, it is made of an elastic material, and when the user wears to walk is pressed by the load is formed to increase the area in contact with the ground.

The front outsole 200, in the state of placing the shoe sole 1 of the present invention on the ground, the rear portion is made to contact the ground, the front portion is made of a curved form lifted from the ground. Accordingly, at the moment when the wearer's front heel touches the ground and is pressed, the rear portion of the front outsole 200 touches the ground, and the center of gravity moves to the front heel until the shoes fall from the ground, the front outsole The surface extending from the rear to the front of the 200 is in continuous contact with the ground. In this process, smooth rolling is achieved.

The rear outsole 300 is coupled to the rear of the bottom surface of the midsole coupling body 100 and together with the front outsole 200 constitute a part of the bottom surface of the shoe. The rear outsole 300 is also formed in an arc shape, and the bottom surface is rounded, and only a relatively small portion is formed to contact the ground.

The rear outsole 300, in the state of placing the shoe sole 1 of the present invention on the ground, the front portion is made to contact the ground, the rear portion is made of a curved form lifted from the ground. Accordingly, at the moment when the wearer's heel touches the ground and is pressed while walking, the most rear part of the rear outsole 300 touches the ground, and the center of gravity of the weight moves forward to the bottom of the rear outsole 300. The front side of the face will touch continuously. That is, from the rear of the bottom of the rear sole 300 to the front continuously to the ground, the gradual load is applied to the heel of the landing foot, smooth rolling is made.

The connector 400 is a portion connecting the front outsole 200 and the rear outsole 300 and constitutes a part of the bottom surface of the shoe sole 1 of the present invention. The connecting member 400 is located in the front and rear ends of the front outsole 200 and the rear outsole 300, respectively, so that the natural rolling from the rear outsole 300 to the front outsole 200 when rolling do.

The connecting member 400 is made of an elastic material, but is made of a relatively hard, even when bent is formed so as not to be deformed enough to touch the ground. That is, the connector 400 is formed so as to act as a pedestal in the shoe sole 1 of the present invention, it is preferably made of a relatively hard material of about 35 ° ~ 50 °.

Therefore, the connector 400 is not significantly deformed and bent even when a load by weight is directly applied on the upper side thereof, and thus the load can be sufficiently endured. Accordingly, in the process of moving the center of gravity from the rear outsole 300 to the front outsole 200, the load may be concentrated on the connecting body 400, and the weight is only in a state in which the heel or the front heel is biased. Rather than being applied by the load, it is possible to withstand the load at the center of the sole, it is possible to prevent the excessive load applied to the joint, and the correct walking can be made.

Shoe sole 1 according to the present invention, the overall shape of the bottom surface is made of a curved shape, such as a bow, made to contact the ground at two points of the front outsole 200 and the rear outsole 300. In the case of a normal masai walking shoe, it is made to touch the ground only at one point of the bottom surface, and in the case of simply wearing the shoe, the portion contacting with the ground is relatively narrow and is formed to be tilted back and forth, indicating an unstable structure. Moreover, the sole is thicker than normal shoes, adding to this unstable structure.

The present invention, as described above, while making the masai walking, the shoe outsole that can improve the structural stability by allowing the load is distributed and supported at two points of the front outsole 200 and the rear outsole 300 Provide (1).

In addition, in the case of the existing masai walking shoes, the thickness of the sole is abnormally thick, especially in the middle bulge protruding because of the heterogeneity, there is a lot of cases reluctant to wear by a hateful shape. However, in the case of the shoe sole 1 according to the present invention, the center portion is formed to be relatively thin to provide an appearance made of a slender shape, and this heterogeneity can be significantly reduced.

In addition, the present invention is not only a smooth rolling movement is made in the process of rolling when walking, but also sufficient pressure can be made in the center of the sole by the connecting body 400 protruding upward, from the heel to the heel It provides the advantage that uniform acupressure is possible across the sole of the foot.

The surfaces are made to form curved surfaces that are close to each other.

The midsole binder 100 is not divided into two parts as described above, but is divided into three parts such as the upper midsole 130, the middle midsole 140, and the lower midsole.

The upper midsole 130 is located on the upper side of the midsole binder 100, it is preferably formed of a polyurethane of 35 ° ~ 50 ° hardness.

The middle midsole 140 is located below the upper midsole 130. The middle midsole 140 is made of a softer material than the upper midsole 130, and preferably formed of a soft polyurethane having a hardness of about 23 ° to about 33 °. The middle midsole 140 may be formed in a form in which the layers are completely separated from the upper midsole 130, but may be formed in a shape located in the upper midsole 130. That is, the middle midsole 140 may be formed to be wrapped by the edge of the upper midsole 130.

By forming the middle midsole 140 softer than the upper midsole 130, a greater impact absorption is made in the middle midsole 140, the upper midsole so that the change due to the shock absorption is not made rapidly Since the 130 is made to be softly elastic deformation can be made smooth buffering and rolling.

The lower midsole is made of the same shape as the second midsole 120 and is made of polyurethane having a hardness of 55 ° to 65 °. The lower midsole is formed in a form protruding upward from the central portion, and is made of a harder material than the middle midsole 140 and the natural force is rolled by the rear portion lifted to the rear.
