Description

Multifunctional shoe sole {Shoe sole}

The present invention relates to a shoe sole, and more particularly, to a multi-functional shoe sole, characterized in that the midsole is made of a double material and configured to induce acupressure effect and correct walking.

One of the essential elements in the construction of a shoe is a shoe sole, and more specifically, the shoe sole can be divided into an outsole, a midsole, and an insole. Among these three, the midsole is considered to be very important because it is a part that absorbs the shock generated when walking.

The primary reason for wearing shoes is to prevent trauma, but in recent years, much research and efforts have been focused on the development of shoe soles that can be more comfortable and help health.

The foot is an important part of the human body so as to be called the second heart, and it is known that there are many benefits of stimulating the sole of the foot.

A related prior art is the first "outsole using acupressure" of patent application No. 10-2005-0034249, Figure 1 shows a schematic configuration for this. In the case of the above technology, the acupressure protrusions 3 are placed on the upper surface of the midsole 1, and the acupressure protrusion grooves 4 through which the acupressure protrusions 3 can penetrate the insole 2 are used for the acupressure during walking. Dragon protrusions are configured to directly stimulate the soles.

Another prior art has disclosed a "free bend sole" of Patent Application No. 10-2007-0056369 and Figure 2 corresponds to a partially cut perspective view of the sole accordingly. The shoe sole has a sole 1 and a midsole 2 stacked therein, and the midsole 2 has a double structure with a hard upper layer 3 and a soft lower layer 4 and the upper layer 3 and the lower layer 4. The upper surface of the lower layer 3 and the upper surface of the lower layer 4 are formed to correspond to each other so that the boundary portion of the wave form a wave shape.

As mentioned in the related art, a more active and effective acupressure effect is not obtained, and shock absorption is possible, but there is a problem in that an effect of inducing correct walking is not obtained at all.

In order to compensate for the disadvantages of the prior art to provide a shoe sole having better characteristics, the present invention is basically to configure the midsole is composed of a first midsole and a second midsole composed of different materials and the first midsole is hard and second The midsole is soft, but the second midsole is bonded in the form of filling the first midsole, and a plurality of binding protrusions having different heights depending on the position are formed on the upper surface of the first midsole, so that the acupressure effect is generated through the soft second midsole. To be delivered to the same time at the same time through the height adjustment of the coupling projections to provide a shoe sole to enable correct walking.

In order to solve the problem as described in the present invention, in the shoe sole comprising a midsole made of two different materials, the outsole is attached to the lower surface of the first midsole made of hard and the inner surface along the edge To form a depression area that is generally recessed and to place the acupressure protrusions having various heights according to the position in the depression area, the outer side acupressure protrusions in the portion corresponding to the sole arch to the height of the foot so as to induce normal walking is higher than the inner acupressure protrusions The second midsole coupled to the recessed area is soft and has a concave groove opposite to the acupressure protrusion formed on the lower surface thereof, thereby proposing a multifunctional shoe sole which enables acupressure effect and correct walking.

Preferably the acupressure protrusions propose a multifunctional shoe sole characterized in that it is any one of an independent round dome shape or a bar shape of convex curvature integrally formed on the same horizontal line.

In addition, more preferably, the second midsole proposes a multifunctional shoe sole, wherein a plurality of auxiliary acupressure protrusions protrudingly protrude from the upper surface thereof.

In addition, the acupressure protrusion is proposed to have a multifunctional shoe sole characterized in that it has a recessed groove that is recessed from the vertex portion to form an empty space.

According to the multifunctional shoe sole according to the present invention, shock absorption can be smooth and at the same time provide acupressure effect, and also can lead to correct walking can contribute to maintaining the health as well as the comfort of the shoe wearer and to correct the wrong step It can also provide an effect.

Hereinafter will be described in more detail with respect to the multi-functional shoe sole according to the present invention, to help the understanding of the present technology as a preferred embodiment. The accompanying drawings are also examples that illustrate preferred embodiments.

Figure 3 shows a schematic cross-sectional view of a shoe sole configured according to the first embodiment of the present invention, Figure 4 is a plan view of the first midsole constituting the shoe sole, Figure 5 shows a plan view of the second midsole will be. 6 is a cross-sectional view taken along the line B-B 'in FIG. 3, FIG. 7 is a cross-sectional view taken along the line C-C', and FIG. 8 is a cross-sectional view taken along the line D-D '.

The multifunctional shoe sole according to the present invention comprises an outsole 100, a midsole 200, an insole (not shown), and in particular, the midsole 200 includes a first midsole 200a and a second midsole having different materials. 200b. The second midsole 200b is positioned on the first midsole 200a to be combined with each other to form one complete midsole 200. The first midsole 200a is made of hard and the second midsole 200b is Make it soft. Hard and soft are relative, meaning that the first midsole 200a is harder than the second midsole 200b. In general, the production of the midsole adopts a foaming method. Production of the first midsole and the second midsole is possible. Naturally, it is also possible to employ a variety of well-known materials for shoemaking.

The outsole 100 is attached to the lower surface of the first midsole 200 (hard), and the outsole 100 is in direct contact with the ground to prevent slippage. In addition, a depression area 210 is formed on an upper surface of the first midsole 200a, and the entire interior of the first midsole 200a is recessed. In addition, the depression area 210 is provided with a plurality of acupressure protrusions 220 and the acupressure protrusions 220 have various heights according to their positions. In particular, as shown in FIG. 7, the outer side acupressure protrusions 220 formed on the same horizontal line in a portion corresponding to the sole arch of the acupressure protrusions 220 are formed to have a lower height than the inner side acupressure protrusions 220. It is composed. In addition, the acupressure protrusions located along the same horizontal line of the front part are to have almost the same height, and in the case of the heel part, the center is the highest and the surroundings are preferably lower than the center. Overall, in the longitudinal direction, the height of the acupressure protrusions toward the anterior portion from the heel is suitable to form the aspect that is lowered. Here, it can be said that it is an area having an imaginary width that can be compared between roughly neighboring acupressure protrusions called "on the same horizontal line". On the other hand, as shown in Figure 4 the height of the acupressure protrusions can be configured in various ways, the number displayed inside the one acupressure protrusions indicates the relative height of each acupressure protrusions, the higher the number means that the height of the acupressure protrusions is formed. . And in understanding the present invention, it is preferable not to compare the height of the acupressure projections one by one but to grasp the overall tendency. That is, it can be seen that the arch portion has a tendency of forming the inner portion as a whole higher than the outer side.

On the other hand, of the plurality of acupressure protrusions 220 formed in the first midsole (200a) it is preferable that the height of the acupressure protrusions formed at a position corresponding to the molten blood of the sole corresponding to the arch portion is the highest.

The acupressure protrusion 220 formed on the first midsole 200a may be any one of an independent round dome shape or a long rod shape that is integrally formed on the same horizontal line to form a convex curvature. More preferably, as shown in FIG. 9, each of the acupressure protrusions 220 may have recessed recesses 225 recessed downwardly to a predetermined depth around the convex apex to form an empty space. It may vary depending on the shape of the acupressure protrusion 220 of the recessed groove 225 and in the case of the independent acupressure protrusion 220 of the round dome shape is to be recessed in a circular shape and in the case of a long rod type (not shown) May be discontinuously depressed in the form of a straight line. This is because the recessed groove 225 may contribute not only to the acupressure action by the acupressure protrusion but also to increase the shock absorbing function at the same time.

When the recessed groove 225 is provided, a third material may be additionally embedded in the recessed groove so as to achieve additional efficacy. The third material may be, for example, a mineral known to provide benefits to the human body, such as a magnet, jade, and germanium.

A second midsole 200b is coupled to the recessed area 210 provided in the first midsole 200a. The lower surface of the second midsole 200b is concave groove 230 corresponding to the acupressure protrusion 220. ) Is formed to be combined with each other in the shape of male and female. That is, the portion of the concave groove 230 to which the acupressure protrusion 220 is coupled is formed to be the thinnest so that the acupressure by the acupressure protrusion 220 can be transmitted to the sole. As mentioned above, the second midsole 200b is made softer than the first midsole 200a and integrally formed in the recessed area 210 of the first midsole 200a.

The upper surface of the second midsole 200b may be a smooth surface without irregularities, but preferably, a plurality of auxiliary acupressure protrusions 240 protruding from the upper surface of the second midsole 200b are suitable. Do. A preferred forming position of the auxiliary acupressure protrusions 240 is to be disposed between the acupressure protrusions 220 formed in the first midsole 200a.

In constructing the shoe, the insole is disposed above the midsole 200 and the upper is combined to constitute a single shoe. As the auxiliary acupressure protrusion 240 is placed on the upper surface of the second midsole 200b, the impact relief is better. Can be done. Since the second midsole 200b is made of soft material, the substantial acupressure effect by the auxiliary acupressure protrusion 240 will be insignificant, and contributes to the improvement of the shock absorbing function.

Multifunctional shoe sole according to the present invention is based on providing acupressure effect, but at the same time has the feature of enabling correct walking. Hereinafter, a function for enabling correct walking by the present invention will be described.

Attached Figure 10 corresponds to the direction of movement of force in the sole showing the direction of movement of the force acting on the sole during normal correct walking. In the walking motion, the heel is first landed on the ground and moves forward while rolling. When walking, the force is applied at the center of the heel, and when it is moved to the arch, the force is moved to the outside of the foot, and then the force is applied to the center while going to the front. This series of force movements occurs in normal walking.

In the present invention, in order to enable such walking artificially, in particular, a plurality of acupressure protrusions formed in the area corresponding to the arch portion so that the outer portion is lower than the inner portion so that the movement of force can be directed to the outer portion.

Multifunctional shoe sole according to the present invention can be applied to general sneakers or shoes, and is expected to be applicable to shoes for the purpose of gait correction.
