Description

Functional shoes {Functonal shoes}

The present invention is a functional shoe having a structure in which an inclined upper portion is formed in the longitudinal direction of the outsole and the midsole of the sole, each of which has an upward inclination in the longitudinal direction, compared to a rear sole in which a heel part is located. When the body balance is landing stably, the pedestrian is comfortable to walk by the natural weight shift due to the inclination angle of the midsole even if the pedestrian does not give strength to the legs. It relates to a functional shoe characterized in that it can improve the driving force and agility.

The Masai shoes, which are very popular these days, are functional walking shoes designed to reduce foot fatigue, and have various structures as known in Korean Patent Nos. 10-800060, 10-786556, and 10-800061. Functional walking shoes are registered. The functional walking shoes as shown in Figure 1, the height of the portion where the toe (toe) portion of the front window and the heel portion of the rear window is located respectively compared to the center of the outsole bottom surface respectively h ₁ , h ₂ As a shoe with a high structure, the conventional Maasai walking functional shoe has no problem in walking while wearing it, but it is unstable to balance the body at the center of the outsole bottom when climbing up or down a slope or stairs. Difficult to the calf is difficult as the leg is fatigued easily, there was a problem such as pre-operation for the next stride becomes unstable.

On the other hand, the inventors of the present invention to reduce the fatigue of the foot when walking as shown in Figure 2 to the Republic of Korea Patent Registration No. 10-533575, the heel part (heel part) formed horizontally with the midsole 100 is formed horizontally (toe) part) and the functional shoe consisting of a slanted portion slantly upwardly sloping from the heel portion to the toe portion, but has received a patent registration in the case of the functional shoe as described above, the height of the toe-cap (toe-cap) (200) There was a problem that can not walk naturally because the tow-cap hits the ground frequently when walking high.

Therefore, the present inventors improve the above-described problems by improving the structure of the outsole and the midsole of the shoe at the same time, and to produce a functional shoe with a lower toe-cap as a solution to solve the problems as described above to complete the present invention. I can do it.

The present invention is a functional shoe having a structure in which an inclined upper portion is formed in the longitudinal direction of the outsole and the midsole of the sole, each of which has an upward inclination in the longitudinal direction, compared to a rear sole in which a heel part is located. When the body balance is landing stably, the pedestrian is comfortable to walk by the natural weight shift due to the inclination angle of the midsole even if the pedestrian does not give strength to the legs. The purpose is to provide a functional shoe characterized in that it can improve the driving force and agility.

The present invention for solving the above problems in the shoe consisting of a shoe sole and an upper,

The shoe sole is a functional shoe characterized in that the front sole is located in the outsole and the midsole (toe part) is located in the longitudinal direction is formed in the longitudinal direction compared to the rear window in which the heel part (heel part) is located. As the means for solving the problem.

However, the outsole has a structure in which a straight inclined portion is formed in which the front window is raised in the longitudinal direction from the rear window, and the midsole is a heel part to a toe part. It is characterized in that the structure is formed with a straight inclined portion gently raised in the longitudinal direction.

According to the present invention by the above-mentioned means for solving the problem, the outsole and the midsole of the shoe sole is formed with an upward inclination in the longitudinal direction compared to the rear window in which the toe part is located, respectively, the heel part is located. Regarding the functional shoes of the structure, the body's balance is landed stably when walking, and the walking is comfortable by the natural weight movement by the inclination angle of the midsole even when the pedestrian does not put pressure on the legs, and the muscles of the lower body of the pedestrian are developed. It increases the amount of exercise, and at the same time has the effect of improving endurance, momentum and agility.

The present invention devised to achieve the above object in the shoe consisting of a shoe sole and an upper,

The outsole and the midsole of the sole are related to functional shoes having a structure in which an inclined portion is formed in an upward direction in a longitudinal direction compared to a rear window in which a toe part is located.

Since the bottom surface of the rear window is horizontally formed, the functional shoe according to the present invention stably lands the body balance when walking, and the walking is caused by the natural weight shift by the inclination angle of the midsole even when the pedestrian does not put pressure on the legs. It is easy to develop the muscles of the lower body of pedestrians to increase the amount of exercise and at the same time improve endurance, propulsion and agility.

In the present invention, the 'front window' and 'rear window' are the boundary surface at which the inclined portion of the front window connected to the rear window is started, and the front window of the portion where the toe part is located in front of the boundary surface (OFL) The window of the part where the heel part is located is called a rear window OBL, and includes both the front window OFL and the rear window OBL. In addition, the toe part (toe part) refers to the part where the toes touch the sole, and the heel part (heel part) means the part where the heel touches the sole.

In addition, in the accompanying drawings, the toe part and the heel part are specifically illustrated with reference to the midsole for convenience in the accompanying drawings, but in the case of the outsole, respectively, the part of the position corresponding to the midsole is the tow part, respectively. It is described as a toe part and a heel part.

And in the present invention, the toes of the body refers to the sole of the foot corresponding to the phalanges (趾骨), the heart of the body (掌心) refers to the sole of the foot corresponding to the metatarsal (中 (), the heel portion of the body ankle It is defined as referring to the plantar portion corresponding to 根骨). In addition, the toe part (toe part) refers to the upper surface portion of the sole where the toe is seated, the inclined portion refers to the upper surface portion of the sole where the heart is seated, the heel part (heel part) refers to the upper surface portion of the sole on which the heel is seated Say.

Hereinafter, the configuration of the functional shoes according to the present invention will be described in detail with reference to the accompanying drawings.

Each of the accompanying drawings is omitted or briefly shown for the components commonly known to those skilled in the art, and shown around the components related to the present invention. In particular, the size ratio between the components are somewhat differently expressed, but the differences in these drawings are easily understood by those skilled in the art, so a separate description is omitted.

In the present invention, Figure 3 relates to a side view of the shoe for explaining the technical spirit of the functional shoe according to the present invention, Figure 4 is a cut in the longitudinal direction of the outsole and the midsole of the functional shoe in accordance with a preferred embodiment of the present invention It relates to a cross-sectional view showing a cross section, Figure 5 relates to a perspective view showing a midsole of a functional shoe according to a preferred embodiment of the present invention.

Functional shoes according to the present invention is a shoe sole consisting of a bottom that is seated on the ground when the wearer walks and the top of the wearer's sole, and an upper that is combined with the shoe sole and wraps the toe, heel, instep and ankle of the wearer as a whole. In the conventional shoe made of, the outsole 10 and the midsole 20 of the sole is characterized in that the front sole where the tow portion is located is formed in the inclined portion in the longitudinal direction compared to the rear window where the heel portion is located.

Therefore, the functional shoe having the above structure can be stably landed on a sloped ground or stairs, so that the foot can be stably landed compared to the conventional Masai shoes, since the bottom surface of the rear window is formed horizontally. When walking on a flat surface, the pedestrian is comfortable to walk by the natural weight shift due to the inclination angle of the midsole even if the legs do not give power.

Referring to the structure of the outsole (outsole) in the present invention in detail with reference to the accompanying drawings as follows.

The outsole 10 according to the present invention has a structure in which a straight inclined portion in which the front sole OFL is raised in the longitudinal direction from the rear sole OBL is formed, and the length of the rear sole OBL versus the length of the front sole OFL is 53 ~. It is preferable that the inclined portion is formed at a point of 56 to 44 to 47, and the inclined portion is an upward structure having an inclination angle α of 13 to 17 degrees. In the present invention, the entire length of the front sole OFL forms the inclined portion.

The formation point and the angle of inclination angle are ergonomically designed, and if the formation point of the inclination portion is formed earlier than the above-defined range or the inclination angle is small, the body balance is stabilized during landing when walking. When the inclination angle of the front windshield is small, natural elasticity movements are not properly implemented, and the force is applied to the leg a lot, and when the formation point of the inclination portion is formed at the rear part more than the above-defined range or the inclination angle is large, the inclination angle of the windshield is large. A lot of force goes into the leg for the preliminary operation to take the next step, and the body balance is unstable when landing at the landing point when walking, so that the pedestrian easily feels tired.

And described in detail with reference to the accompanying drawings the structure of the midsole (midsole) in the present invention as follows.

The midsole 20 according to the present invention is characterized in that the present inventors have adopted and improved the midsole structure of the functional shoe, which has already been patented by the Republic of Korea Patent Registration No. 10-533575, and the pedestrian feels as tired as possible when worn. Ergonomically designed to make you feel less.

Accordingly, the midsole 20 according to the present invention has a structure in which a straight inclined portion is gently formed in the longitudinal direction from the heel portion 23 to the toe portion 21, and the midsole has a length of the tow portion MTL. It is preferable that length (ML) of the whole midsole is 0.2-0.3 to one. If the length of the toe portion is less than 0.2, the wearer's core portion is settled over the toe portion 21 and the inclined portion 22, so the feeling of wearing is lowered. Since it is seated continuously over the inclined portion 22, there is a fear that a problem that the wearing feeling is lowered.

Moreover, it is preferable to form the length of the heel part 23 (MHL), and the length ML of the whole midsole in a ratio of 0.15-0.21 to 1. When the length of the heel portion 23 (MHL) is less than 0.15, the entire heel, which is a portion corresponding to the ankle foot, of the skeleton constituting the human foot does not touch the heel portion 23 and the inclined portion 22 There is a problem in that the feeling of wearing falls by touching over the heel 23, if there is more than 0.21 there is a fear that a problem that the wear is reduced because the wearer's heart portion is seated over the inclined portion 22 and the heel 23. .

In addition, the midsole 20 forms a moderately straight upward inclined structure in which the inclination angle β from the heel 23 to the toe 21 is 2.5 to 4.0 °, so that the toe portion does not slip while walking. As it is naturally seated, the feeling of wearing is improved, and since it is set at an appropriate inclination for walking and exercising, it is characterized by being able to effectively increase the amount of exercise without difficulty in the Achilles tendon even when walking or exercising for a long time.

When the inclination β of the inclined portion 22 is less than 2.5 °, the relaxation degree of the Achilles tendon is insufficient and the amount of exercise is small, so there is a problem in that it is not possible to formulate the desire of modern people to effectively increase the exercise amount by a simple exercise. If it is more than 4.0 °, the Achilles tendon has a large degree of relaxation, but there is an advantage in that the momentum is extremely increased, but there is a fear that the fit is degraded, the balance is lost, and the Achilles tendon is unreasonable.

In the present invention, the material used for the outsole 10 and the midsole 20 is generally a material used for the shoe outsole and the midsole, preferably a polyurethane (PU) or EVA foam, and the foam material defined above. In addition, in the case of a foam material having the same or more physical properties, its use is possible regardless of the kind of the material.

Therefore, in the functional shoe having the above structure, both the outsole 10 and the midsole 20 of the sole are formed in a structure in which the toe portion is gently inclined upwardly compared to the heel portion, so that the balance of the body is stably landed when walking. It is ergonomically designed so that it is easy to walk due to the natural weight shift due to the inclination angle of the midsole, and the endurance, driving force and agility can be improved while increasing the amount of exercise by developing the muscles of the lower body of the pedestrian.

As described above, the present invention has been described for the superiority of the present invention with reference to the accompanying drawings, but the present invention is not necessarily limited only by the accompanying drawings, and various modifications may be made without departing from the spirit of the present invention. Substitutions, modifications and variations are possible.
