Description

Shoe sole for active walking

The present invention relates to the sole of a shoe worn by all men and women of all ages for healthy walking, and more specifically, while the active walking such as Masai walking is possible, the appearance relates to a shoe sole similar to a normal shoe.

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 be beneficial to 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.

And, 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 is to solve the problems described above, an embodiment of the present invention is to dualize the material of the midsole, and to configure the center portion of the outsole and the lower midsole flat, having a shape similar to that of ordinary shoes, active Related to making walking possible.

Suggest.

According to an embodiment of the present invention as described above, first, the upper midsole uses a relatively soft material, and the lower midsole has an arc shape in the front and rear direction as a whole, and the center of the upper part is convex and the center of the bottom part. Is formed in a flat, the front and rear holes are formed in the front and rear of the lower midsole, respectively, the natural active walking around the center can effectively occur, the center portion is in contact with the ground has a sense of stability.

Second, in the landing and center movement stage, the rear hole distributes the landing shock evenly, does not cause discontinuous impact on the ankle joint, leg and body, and acts as a cushion to allow smooth landing and natural walking. It absorbs the impact of the heel after active walking.

Third, around the front and rear holes, there is a first through hole penetrating the upper midsole and a second through hole penetrating the lower midsole, so that the air in the front and rear holes expands and contracts during active walking. By pumping the circulating moisture and heat concentrated in the toes and the sole area can be removed athlete's foot and foot odor.

Fourth, in the front and rear holes to form a number of acupressure rods, it is possible to continue acupressure through active walking, thereby promoting blood circulation can reduce the fatigue during long walks.

Fifth, in the case of the existing active walking shoes, the outsole is generally arc-shaped, unlike general shoes, and the appearance is not good, and rejection occurs when it is worn. good.

Hereinafter, a preferred embodiment of a shoe sole for active walking according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Shoe sole (1) according to a preferred embodiment of the present invention, the overall shape is arc-shaped in the front and rear direction, the central portion of the upper end is convex, the lower midsole 12 is formed flat in the center; An upper midsole (11) formed integrally with the lower midsole (12) and made of a softer material than the lower midsole (12), and having an upper surface formed in a curved shape corresponding to the sole; And an outsole 20 attached to a lower portion of the lower midsole 12, wherein a front hole 12a and a rear hole 12b are formed at front and rear sides of the lower midsole 12, respectively. The inside of the hole 12a and the rear hole 12b is filled by the upper midsole 11.

As shown in the cross-sectional view of the midsole of FIG. 3, the midsole 10 is divided into two parts, the upper midsole 11 and the lower midsole 12, wherein the upper part is on the lower midsole 12. The midsole 11 is located.

The midsole 10 is preferably made of polyurethane (Poly Urethane), in particular, the lower midsole 12 is made of a relatively hard (硬 質), the upper midsole 11 is composed of a relatively soft (軟 質) do.

That is, in the shoe sole according to the preferred embodiment of the present invention, one of the midsoles 10 formed by short-forming two different hardness polyurethanes is provided.

As a result of the evaluation, the lower midsole 12 is a polyurethane of 55 degrees to 65 degrees, the upper midsole 11 is an effective characteristic according to the difference in hardness when using a polyurethane of 30 degrees to 45 degrees of hardness.

In addition, in the case of the upper midsole 11 made of a soft polyurethane, damage may occur due to hydrolysis, and thus, the midsole may be formed by simultaneously forming a TPU (Temperature Poly Urethane) film on the surface, which may help tensile or compression. (10) can also be produced.

The lower center portion of the lower midsole 12, unlike the case of a shoe sole for the conventional active walking, is formed in a flat rather than a perfect arc, the upper center portion is formed convex.

Due to this morphological characteristic, a natural active walking can take place effectively around the center portion of the lower midsole 12, and the bottom portion of the bottom of the shoe in which the shoe sole 1 according to the present invention is used is brought into contact with the ground. The stability is improved.

The outsole 20 coupled to the lower portion of the midsole 10 is made of synthetic resin or synthetic rubber having a high friction coefficient, and is made of a relatively hard material as compared to the midsole 10.

The lower surface of the outsole 20 is a part which is in direct contact with the ground, and grooves of various patterns are formed, which is to increase walking friction by increasing friction with the ground.

A front hole 12a is formed at a front side of the lower midsole 12 and a rear hole 12b is formed at a rear side thereof, and the front hole 12a and the rear hole 12b are respectively formed at the upper midsole 11. Is filled.

That is, as shown in the cross-sectional view of the upper midsole of FIG. 4, the lower surface of the upper midsole 11 protrudes convexly by filling the lower midsole 12.

In the landing and moving center step, the rear hole 12b uniformly distributes the landing shock and does not cause discontinuous impact on the ankle joint, leg and body, and serves as a cushion to allow smooth landing and natural walking.

In addition, as the front hole 12a is positioned, shock absorption of the front heel is possible at the time of moving the center from the heel to the front heel.

In the shoe sole according to the preferred embodiment of the present invention, the front hole 12a and the rear hole 12b are formed by penetrating the lower midsole 12 up and down.

The largest height of the front hole 12a and the rear hole 12b is when the front hole 12a and the rear hole 12b completely penetrate the lower midsole 12 up and down.

In this case, the height of the upper midsole 11 filled in the lower midsole 12 is the highest, and unlike the hard center portion of the lower midsole 12, the degree of contraction of the soft upper midsole 11 filled up and down is It is the largest, leading to natural active walking.

In addition, the higher the height of the soft upper midsole 11, the greater the cushioning effect.

In the shoe sole according to the preferred embodiment of the present invention, the front hole 12a is formed in an oval shape based on the center of the user's front heel, and the rear hole 12b is formed in an oval shape based on the center of the heel.

When the front hole 12a and the rear hole 12b are formed and the upper midsole 11 is filled in the portion corresponding to the portion where the center of the front heel and the center of the heel are loaded, the hard lower part Unlike the central portion of the midsole 12, the filled soft upper midsole 11 can be easily shrunk as a whole, so that natural active walking is induced.

That is, it is preferable to form the front hole 12a and the rear hole 12b in a shape as shown in the plan view of the shoe sole of FIG. 7.

In this case, as the soft upper midsole 11 is filled, a shock absorbing effect can also be expected.

9 is a plan view showing a shoe sole according to another embodiment of the present invention, Figure 10 is a cross-sectional view of the shoe sole viewed from A-A ', B-B', C-C 'of FIG.

In the shoe sole according to the preferred embodiment of the present invention, a plurality of first through holes 31 are formed in the upper midsole 11 filling the front hole 12a and the rear hole 12b, and the front hole 12a. And a plurality of second through holes 32 penetrating the lower midsole 12 around the rear hole 12b.

In order to move the air in the front hole (12a) and the rear hole (12b), a through hole is formed, the outside air can move into the front hole (12a) and the rear hole (12b) The second through hole 32 is formed through the lower midsole 12, and may be formed at least one.

One or more first through holes 31 are formed in the upper midsole 11, and the first through holes 31 and the second through holes 32 are connected to each other so that the outside air moves to the sole of the foot. Done.

The shape and number of the first through holes 31 and the second through holes 32 are formed so that proper pressure can be generated in consideration of Pascal's law.

For example, when the first through-hole 31 and the second through-hole 32 are formed in a funnel shape and connected, the cross-sectional area of the passage through which air moves is not constant, and the narrower the area of the funnel tip is, the narrower the area is. The higher pressure is generated, the pumping effect of the active walking can be expected.

If grooves are formed at each position of the insole corresponding to the second through hole 32, the sole of the user is always in contact with fresh air, thereby circulating moisture and heat concentrated on the toes and the sole of the foot, thereby causing athlete's foot and foot odor. Can be removed.

11 is a plan view showing a shoe sole according to another embodiment of the present invention, Figure 12 is a cross-sectional view of the shoe sole viewed from A-A ', B-B', C-C 'of FIG.

In the case of a shoe sole according to a preferred embodiment of the present invention, a plurality of acupressure rods 40 are formed in the front hole 12a and the rear hole 12b.

Since the upper midsole 11 uses a relatively soft material, the bearing pressure by the acupressure rod 40 under the upper midsole 11 can be effectively transmitted to the sole, and the upper midsole even when walking for a long time. Since the acupressure is transmitted through (11), a comfortable acupressure is possible.

The shape of the shiatsu rod 40 is formed in a cylindrical shape and the end is preferably formed to have a convex curvature, but is not limited to this, of course, can be manufactured in various shapes.

For example, the end of the chiropractor 40 may not have a curvature, or may form a concave curvature. The acupressure rod 40 may be manufactured in various forms such as a star shape, a butterfly shape, and the like as seen from above.

The shiatsu rod 40 is preferably formed integrally at the upper end of the outsole 20, the portion of the shiatsu rod 40 and the upper midsole 11 is coupled to the shiatsu rod 40 as the male and female of the screw is coupled. Correspondingly, concave portions are formed and joined to each other.

The height of the shiatsu rod 40 can be changed according to the position.

That is, in the case of the conventional acupressure shoe, the height of the acupressure rod 40 does not vary by position, so that the same acupressure is transmitted as a whole. Differently, it affects each reflex stimulus distributed on the sole, thereby activating metabolism and improving blood circulation, which is good for health.

The height of the pressure bar (40), from the inside to the outside when viewed from the front, the height of the pressure bar (12a) gradually increases and lowers, and when viewed from the side, the height of the pressure bar (12a) from the front to the rear gradually increases and then lowers It is possible to form, wherein the height of the highest part is preferably based on the yongcheon blood of the sole.

In short, yongcheon blood is called the blood of the spring of life, and compared to the center of the sole of the foot slightly above the thumb, because the stimulation of the fatigue is eased, and the effect of lowering blood pressure.

Not only the height of the shiatsu bar 40 but also the shape of the shiatsu bar 40 can be changed depending on the position.
