Description

Shoe sole for health {shoe sole for health}

The present invention relates to the sole of a shoe worn by all men and women of all ages for healthy walking, and more particularly, relates to a shoe sole capable of active walking, such as so-called masai walking, and exhibiting the effects 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 erroneous walking adversely affects joints and muscles, which harms the overall health of the body. Accordingly, interest in walking and foot health is increased, and various kinds of walking correction or reduction of foot fatigue can be caused. 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 made of 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.

In recent years, as the theory that the foot of the human body has a great influence has emerged, the interest in the protection and management of the foot is gradually spreading. According to this, as the foot is a miniature version of the human body, and the foot is connected to correspond to the organs of the whole body on the sole, by appropriately stimulating the area, it is possible to maintain the health by activating the overall system function of the human body. Accordingly, interest in shoes having acupressure function is increasing.

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

However, the shoes disclosed in the registered patent is capable of active walking on the ground, but there are some problems.

First, since the structure is only active walking, foot pressure effect on the foot can not be expected.

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 as described above, as the sole of the shoe made to be capable of masai walking, the effect of the acupressure by the projections provided inside the sole while having the sole structure of the shoe is a thick portion of the sole of the sole It is about making sure that it is fully exercised.

According to a preferred embodiment of the present invention, the lower midsole is formed with an acupressure rod of uneven shape at the top; An upper midsole formed integrally with the lower midsole and made of a softer material than the lower midsole; A support plate formed inside the lower midsole and used as a pedestal for acupressure rods to prevent tipping and warping; And an outsole attached to a lower bottom midsole.

According to one embodiment of the present invention as described above, first, since the upper midsole uses a relatively soft material as compared to the lower midsole, the pressure pressure by the pressure bar in the lower portion can be effectively transmitted to the sole.

Second, a support plate for a person's foot type is located under the acupressure rod, which can support the acupressure rod, thereby improving the acupressure effect, and preventing tipping or torsion when an external force is applied to the foot during landing. As a result, the shape of the sole and the shoe can be preserved, and the shape of the shoe sole with high frequency of bending during walking is excellent, and the stability of walking can be improved. .

Third, the outsole consists of arc shape and the movement of the center is increased from the heel to the heel after the landing movement. Compared to shoes, the effect of acupressure is much greater, so that blood circulation can be promoted, thereby reducing fatigue even when walking for a long time.

Fourth, in the landing and center movement stages, the rear tunnel distributes the landing impact uniformly, does not cause discontinuous impact on the ankle joint, leg and body, enables smooth landing and natural walking, and landing stage as the front tunnel is located. During the post-separation phase, the resilience of the tunnel part makes it possible to walk lightly and lightly, adding stability.

Fifth, in the case of the conventional acupressure shoes, the height of the chiropractor does not vary by position, and accordingly, the overall acupressure degree is the same, but the present invention changes the height of the acupressure rod linearly for each sole area, in particular, the acupressure for yongcheonhyeol effectively By doing so, it activates metabolism and improves blood circulation, which can help health.

Hereinafter, a preferred embodiment of a shoe sole for health according to an embodiment of the present invention will be described with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

1 is a perspective view of a shoe using a shoe sole according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing the shoe sole shown in Figure 1, Figure 3 shows the lower midsole shown in Figure 2 4 is a cross-sectional view showing the upper midsole shown in FIG. 2, FIG. 5 is a plan view showing the lower midsole shown in FIG. 2, FIG. 6 is a cross-sectional view showing the outsole shown in FIG. 2 is a plan view of the support plate shown in FIG. 2, FIG. 8 is a side view of the support plate shown in FIG. 2, and FIG. 9 is a cross-sectional view of the support plate seen from A-A 'of FIG.

Shoe sole (1) according to a preferred embodiment of the present invention, the lower midsole 12 and the lower midsole 12 is formed integrally on the upper side of the lower midsole 12, the acupressure rod 12a of the uneven shape formed on the upper end, the lower midsole 12 It is formed in the upper midsole 11 and the lower midsole 12 made of a softer material, and used as a support for the shiatsu rod 12a, and the support plate 30 and the lower midsole 12 to prevent tipping or warping. It comprises an outsole 20 attached to the bottom.

As shown in the cross-sectional view of the shoe sole of FIG. 2, the midsole 10 is divided into two parts, the upper midsole 11 and the lower midsole 12, wherein the midsole 12 is disposed on the lower midsole 12. The upper 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 evaluation, when the lower midsole 12 is a polyurethane of hardness 55 degrees ~ 65 degrees, the upper midsole 11 is an effective characteristic according to the difference in hardness when using a polyurethane of hardness 25 degrees to 35 degrees.

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.

An acupressure rod 12a is formed at an upper end of the lower midsole 12 to have acupressure effect.

Since the upper midsole 11 is made of a material that is relatively softer than the lower midsole 12, the bearing pressure by the acupressure rod 12a in the lower portion can be effectively transmitted to the sole, and also walks for a long time. Even when the pressure is transmitted through the upper midsole 11 it is possible to comfortable acupressure.

The shape of the shiatsu rod 12a is formed in a cylindrical shape, the end is preferably to form a convex curvature, but is not limited to this, of course, can be produced in a variety of shapes.

For example, the end of the chiropractor 12a may not have a curvature or may form a concave curvature. The acupressure rod 12a may be manufactured in various forms such as a star shape, a butterfly shape, and the like as seen from above.

As the shiatsu rod 12a is formed, the lower midsole 12 and the upper midsole 11 are coupled as male and female screws, so that the lower surface of the upper midsole 11 corresponds to the shiatsu rod 12a. As a result, concave portions are formed.

Below the shiatsu rod 12a, there is a support plate 30 suitable for a person's foot type, and as shown in the cross-sectional view of the shoe sole shown in FIG. 2, the support plate 30 has a predetermined distance from the shiatsu rod 12a. It is preferable to be formed to maintain.

Since the support plate 30 supports the acupressure rod 12a, the acupressure effect is improved compared to the case where only the lower midsole 12 is present, and active walking is prevented due to external force or torsion when landing on the ground. This can continue effectively.

In addition, since the support plate 30 is present, the original shape of the shoe sole is maintained for a long time, and the shape of the shoe sole is severely restored during walking, thereby improving stability of the walking.

The support plate 30 greatly improves the strength of the midsole 10, and is excellent in weight reduction and workability of the product, and has excellent properties in various physical properties such as wear resistance, adhesiveness, and water resistance. It is preferable to use a plastic sheet material mixed with Polypropylene).

That is, it is possible to determine the blending ratio of polyester and polypropylene used in the support plate 30 through evaluation of rigidity against torsion.

As shown in the cross-sectional view of the support plate viewed from A-A 'of FIG. 7 shown in FIG. 9, the support plate 30 has a slightly convex shape downward, which is the sole of the foot so as to have a natural active walking along the direction of travel. To collect them.

As shown in the plan view of the support plate shown in Figure 7, it is possible to reduce the weight of the product by forming a plurality of holes penetrating the vertical direction, through which air may move.

That is, when the holes connected to the plurality of holes of the support plate 30 are installed in the upper midsole 11 and the lower midsole 12, air moves during active walking, thereby removing moisture and heat from the sole part of the foot. .

As shown in the cross-sectional view of the shoe sole shown in Figure 2, the outsole 20 is coupled to the lower portion of the midsole (10).

The outsole 20 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.

In the shoe sole according to a preferred embodiment of the present invention, the upper midsole 12 and the upper midsole 11 and the support plate 30 form a curved shape, the outsole 20 is harder than the lower midsole 12 It is made of a material, and the bottom surface is made of arc-shaped to enable masai walking.

That is, the present invention, as shown in the cross-sectional view of the shoe sole shown in Figure 2, because the upper side of the lower midsole 12 and the upper midsole 11 and the support plate 30 form a curved shape, a flat shape It is made to improve the wearing comfort compared to ordinary shoes.

In addition, as shown in the cross-sectional view of the outsole shown in Figure 6, the thickness of the outsole 20 is thinner than the midsole 10, the entire shape from the forefoot to the rear foot through the convex convex down, In the process of moving the center from the heel to the heel after the landing operation, active walking using the joints and muscles from the ankle and the toe is evenly possible.

In addition, the active walking has the effect of delivering a greater pressure than conventional shoes, thereby promoting blood circulation and reducing fatigue even when walking for a long time.

As shown in the cross-sectional view of the shoe sole shown in FIG. 2, the thickness of the lower midsole 12 may be divided into the forefoot, the midfoot, and the forefoot to prevent shock absorption and effective active walking during landing. At this time, the area from the rear end of the midfoot to the front end of the foot is the thickest and gradually decreases in the front-rear direction based on this part.

The upper midsole 11 is formed to have a uniform thickness as a whole so that the pressure effect of the shiatsu rod 12a is transmitted to a uniform degree.

The thickness of the outsole 20 is thinner than the midsole 10 and has a constant thickness as a whole.

In the shoe sole according to the preferred embodiment of the present invention, the lower midsole 12 is formed under the support plate 30, the front tunnel 41 and the rear tunnel 42 to disperse the impact to add stability when landing.

As shown in the cross-sectional view of the sole of the shoe shown in FIG. 2, the rear tunnel 42 and the front tunnel 41 formed of four tunnels are formed in the lower midsole 12. ) And the number of front tunnels 41 can be changed within an appropriate range.

The height of the mid sole 10 is the highest at the portion where the front tunnel 41 and the rear tunnel 42 are positioned, that is, the front tunnel 41 and the front tunnel 41 at a portion extending from the rear end of the middle foot to the front end of the foot. The rear tunnel 42 is located.

In the landing and centering step, the rear tunnel 42 uniformly distributes the landing shock, thus causing discontinuous impact on the ankle joint, leg, and body, and allowing smooth landing and natural walking.

In addition, as the front tunnel 41 is positioned, the resilience of the front tunnel 41 during the detachment step after the landing step enables a light and light walking, thereby adding a sense of stability.

When a plurality of spherical holes are installed in the lower midsole 12 instead of the front tunnel 41 and the rear tunnel 42, these holes are similar to the front tunnel 41 and the rear tunnel 42. It will absorb the shock.

In addition, when forming the tube extending in the vertical, vertical, left and right directions of the holes penetrating the midsole 10, the air can be moved as the hole repeats contraction and expansion during active walking.

The shape and number of tubes formed in the hole are selected to allow effective air movement due to the contraction and expansion of the hole in consideration of the pressure according to Pascal's law.

For example, when the pipe is formed into a funnel shape, the cross-sectional area of the moving passage of the air is not constant, and the narrower the area of the funnel end, the greater the pressure is generated. Therefore, the pumping effect of the active walking is expected. It becomes possible.

If the grooves are formed at each position of the insole corresponding to the pipe passing through the midsole 10, the sole of the user is always in contact with fresh air, so that the athlete's foot and the circulation of moisture and heat concentrated on the toe and the sole area Foot odor can be removed.

10 is a plan view and a cross-sectional view schematically showing a lower midsole according to another embodiment of the present invention.

In the shoe sole according to a preferred embodiment of the present invention, the height of any one part of the shiatsu rod is higher than the other part, so that the shiatsu effect of that part is further exerted.

That is, in the case of a conventional acupressure shoe, the height of the acupressure rod 12a does not vary by position, so that the same acupressure is transmitted as a whole, whereas the present invention changes the height of the acupressure rod 12a for each foot part to change the size of acupressure. By differently affect each reflex stimulus distributed on the sole to activate the metabolism, improve blood circulation will help health.

The height of the shiatsu rod 12a varies depending on the position, and when viewed from the front, the height of the shiatsu rod 12a gradually increases and decreases from the inside to the outside, and when viewed from the side, the height of the shiatsu rod 12a moves from the front to the rear. It is arranged to be gradually higher and lowered, and the highest height 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 position of the thumb, because the stimulation eases fatigue, because it has the effect of lowering blood pressure.

Not only the height of the shiatsu rod 12a but also the shape of the shiatsu rod 12a can be changed depending on the position. In this case, more various shiatsu pressures can be transmitted for each sole part.
