Abstract

PURPOSE: An outsole is provided to maximize resilience and to prevent a user from being fatigued even in walking or running for a long time. CONSTITUTION: An outsole comprises a hollow cushion protrusion(33) in which an internal space(30) is formed. In the hollow cushion protrusion, a non-permeable vinyl sheet is inserted into the cushion protrusion and a space part(11) is formed in the bottom surface thereof. On the bottom(15) of the internal space, the upper side of the cushion protrusion is adhered by force. The compacted hollow cushion protrusion generates restoring force when external force is removed.

Description

Outsole with built-in hollow cushion protrusion with resilient elasticity {omitted}

The present invention relates to a sole window in which a resilient hollow cushion protrusion is embedded. More specifically, the inside of the protrusion pillar is formed by embedding a foamed and expanded cushion protrusion in a size of 5% to 10% higher than the height of a preformed transparent vinyl protrusion pillar. When it is sealed, the foam expansion protrusion is compressed at 5% to 10% with low hardness, and when the external force is received, the external force is dispersed and the shock absorbing force and rebound elasticity are generated quickly. As the inside air does not escape to the outside even after a long period of time, the cushion projection is not easily recessed, and its shock absorption function and resilience are intended to last for a long time.

Ordinary shoes consist of upper, midsole, and outsole. The upper protects the foot by covering the instep and the foot, and the midsole acts as a shock absorber when walking, and the sole has a non-slip function. .

That is, there are various shock absorbing members to block the shock transmitted to the body through the sole of the foot when walking, such as air bags, sponges, gel pockets, springs, etc. These members make a separate space inside the midsole or outsole to create a work process. Mounted through or to achieve a completed shoe sole by the bonding process.

Sole equipped with a shock absorbing member is completed there is a problem to obtain the effects of shock absorption and resilience at the same time. In other words, if the shock absorption is good, the resilient elasticity is weak, and if the resilient elasticity is good, there are problems in that the shock absorption is poor. Therefore, airbags or spring-loaded soles have a problem that the finished shoe soles are inferior in design due to their roughness as the height of the member can obtain a certain degree of shock absorption and resilience.

On the other hand, shoe soles with built-in shock absorbing members have another problem that the weight is heavy.

Therefore, in the present invention, by injecting or vacuum molding, the transparent vinyl sheet is pre-molded into a structure in which a plurality of cushioning projections are attached, thereby incorporating a foam-expanded hollow protrusion having a height of about 5% to 10% in the inside of the cushioning projection space. When sealed with a non-breathable sheet, the foam-expanded hollow protrusion is embedded in a compressed state of 5% to 10%, so that the hollow cushioning protrusion with resilient elasticity is made by the restoring force of the material itself and the forced repulsion force. At the same time, the cushion projections cause shock absorption and rebound elasticity, and the cushion projections are formed by a non-breathable membrane so that the air inside does not escape to the outside and the cushion function lasts for a long time. Due to the hollow projections, there is another advantage that the cushion function is exhibited even in shoes having a low sole height.

The present invention for achieving the problem as described, the non-breathable vinyl sheet in the outsole foam expansion and expansion inside the cushion projection formed with a plurality of cushion projections processed by vacuum molding or injection molding method and foamed space therein When the height of the layer cushion projection is inserted in the state of 5% to 10% higher and another non-breathable sheet is bonded to the upper portion, the inside of the cushion protrusion made of the formed non-breathable membrane becomes a sealed space. The present invention proposes an insole in which foam cushions with foam expansion therein are compressed 5% to 10%.

It is preferable that the non-breathable vinyl sheet and the synthetic resin described above are selected from the Pourye carbon resin having excellent cold resistance, tensile strength, and restoring force.

The present invention proposes an insole in which a hollow cushion protrusion having a resilience elasticity in which a foam layer cushion protrusion is coupled to a non-breathable sheet upper space.

The foamed layer cushioning protrusion in which the non-breathable cushioning protrusion described above is built in is generally referred to as a hollow cushioning protrusion.

In addition, the present invention may have a double structure in which one or more hollow cushioning projections having repulsive elasticity face each other, or the height of the hollow cushioning projections foamed by the bottom of the hollow cushioning projections overlapped with each other may be doubled. Suggest that.

A large number of hollow cushion protrusions with resilient elasticity are adhered to the bottom of a non-breathable sheet inner space with inner space separated from the front and rear, and the inside of the cushion protrusion with foam layer is sealed and has a low hardness foam layer inside. The cushion projection is proposed an outsole in which the hollow cushion projection with a resilient elasticity is built in a state of being compressed 5% to 10%.

Preferably, a hollow cushioning protrusion having a resilience elasticity in the upper surface separated in the front and rear, the bottom surface is exposed to the top suggests a built-in sole.

Preferably, the bottom of the non-breathable plate having a through hole corresponding to the number of hollow cushion protrusions is formed to have a space for the cushion protrusion therein, and a plurality of hollow cushion protrusion protrusions penetrate and are combined to protrude the hollow cushion protrusion protrusions to the upper surface of the non-breathable plate. In this state, we propose an insole with a hollow cushioning projection with a resilient elasticity that can be brought into direct contact with the sole of the foot.

Preferably, a space portion is formed on the upper surface of the non-breathable sheet, and there are proposed an outsole having repulsive elasticity and a cushioning function with cushion protrusions protruding up and down therein.

Preferably, a perforated part divided into a non-breathable plate front part and a rear part is formed, and a hollow cushion protrusion coupled to the inside of the perforated part is coupled to the cushion protrusion upper surface, which is non-breathable and covers a plate having a higher hardness than the cushion protrusion. This suggests an insole with a hollow cushioning projection with resilience.

Preferably, the non-breathable plate has a hollow cushioning protrusion built into the taxon (midsole) having a perforated portion divided into the front portion and the rear portion of the non-foaming layer or a perforated portion only at the front portion thereof, and the non-breathable sheet is covered with the non-breathable plate on its upper surface. It provides a sole with a hollow cushion projection with a resilient elasticity characterized in that.

Preferably, the upper bottom end edge portion and the non-breathable sheet edge attached to the hollow cushioning projection are combined with the sewing material to provide a sole with a hollow cushioning projection having a repulsive elasticity.

In addition, the hollow cushion protrusion protruding surface protrudes into the shoe and comes in contact with the sole of the foot and proposes a resilient insole that can give acupressure effect.

It is preferable to propose a sole having a resilient elasticity visible inside through a transparent window to the bottom side or bottom surface of the sole with a hollow cushion projection.

The outsole according to the present invention is embedded in the foam layer cushioning projections of the foam layer in advance to the vacuum-molded cushioning projections, and the cushioning projections composed of the foaming layers are compressed and embedded about 5% to 10% so as to cause resilience. When it is sealed, the pressure is more easily dispersed when absorbed by the external force, absorbs the shock and the external force is released, and the resilience is maximized as the resilience is maximized.The driving force to push up the sole is generated quickly, so it is easy to walk or run for a long time. There is an advantage that does not get tired. Due to the transparent vinyl sheet film surrounding the foam layer cushion projections, there is an advantage that the shock absorbing force and the resilient elastic force are maintained for a long time since the internal air does not escape to the outside.

In addition, the height of the hollow cushioning projection is installed to lower the resilience in advance, so that the impact absorption and rebound elasticity is made more quickly, so that the driving force is improved, the fatigue of the foot is reduced, and the sole of the shoe is relatively thin shoes or women's high heels. There is another advantage to the technology.

And the outsole referred to in the present invention is expressed insole, midsole, outsole, etc. formed on the sole bottom of the sole according to the situation that fits the function of the shoe.

Hereinafter, a more detailed description will be made with respect to the insole in which the hollow cushioning projection having the resilience elasticity according to the present invention is incorporated, and the related drawings will be referred to to help the understanding of the present invention.

However, the drawings are shown to show one possible example of the technical idea of the present invention and the scope of the drawings itself is not limited. Therefore, it is to be understood that simple modification embodiments such as simple design changes by others or substitution with equivalent components are also included in the technical scope of the present invention.

1 is an exploded perspective view and a cross-sectional view of the outsole according to a first embodiment of the present invention and Figure 2 shows that the cushion protrusion protrusion is exposed to the upper surface.

The structure of the outsole of the present invention is a non-breathable sheet material 10, but is made of an EVA material widely used as a foam layer in the state formed so that the space portion (11) on the bottom of the cushioning projection 22 a plurality of non-breathable vinyl sheet The injection molding or the vacuum molding to insert the hollow cushion projection 33 with the foamed and expanded foam layer in the cushioning protrusions 23 and the inner space 30 and the upper surface 21 of the cushioning protrusions 21 to the inner space bottom 15 Force bonding When the height of the foam layer cushion protrusion 33 is inserted into the cushion protrusion 22 inner space 23 while the height of the foam layer cushion protrusion 33 is about 5% to 10% higher than the cushion protrusion inner space 23, the cushion protrusion of the foam layer is of low hardness. (33) is inserted into the cushion projection inner space 23 while being compressed to a low level of about 5% to 10%. The hollow cushion protrusion 33 in the compressed state receives a distributed pressure when the external force is applied, and the shock absorbing time is shortened. When the external force is terminated, the restoring force is rapidly generated, and the texture seems to push the sole with the driving force due to the resilience. Will feel.

On the other hand, when the hollow cushioning projection is compressed and restored, the cushion projection 22 made of a non-gun-like membrane is also compressed and restored at the same time.

On the other hand, the air remaining in the space 25 around the cushion projection 22 is cushioned due to the widening and narrowing of the unit space of the inner space portion 11 during compression and restoration of the hollow cushion protrusion 22. Air around the protrusion 22 is introduced into the shoe through the through hole 12.

That is, when the space 11 is compressed, the air inside is forcibly discharged into the shoe, and when the unit area of the space 11 is restored, the air inside the shoe is sucked.

On the other hand, the air staying between the hollow cushion projection pillars 22 also has the advantage of causing the function to ventilate smoothly.

Then, the air layer of the foam layer cushion protrusion 33 itself in the cushioning protrusion 22 and the inner space 23 and the air staying in the inner center 30 of the foam layer cushion protrusion are transferred to the cushion protrusion 22 made of a non-breathable sheet film. Since the air does not escape to the outside even after a long period of time, the shock absorption and rebound birth function does not easily sink even after a long period of time.

And a (a) of the lower end of the cross-sectional view shown in Figure 1 (cc) shows the bottom surface of the foam layer cushion protrusion 33 is built in the transparent cushion protrusion 22 and b is a hollow cushion protrusion 33 foam layer is a cushion protrusion ( 22) and compressed state inside the space at the same time.

Figure 3 is a cross-sectional view showing that the hollow cushion projection 22 can be implemented in various forms (b-1) is a hollow cushion projection with a resilient elasticity even when the upper surface of the hollow cushion projection 22 is nested It can be a built-in sole.

In addition, (c-1) and (d-1) shows a structure in which the cushion protrusion protrusion 22a protruding to the upper surface may also protrude into the shoe to pressure the sole of the foot.

In addition, the perspective view of (d-2) is a cross-sectional view showing that the other than the cushion protrusion 33 of the foam layer in the cushion projections may be put in the elastic body, specifically the liquid phase 35 having a viscosity, the air pressure 36 The pressurized pressure may be injected into the outsole to which the cushion protrusion with resilient elasticity is attached.

Figure 4 is an embodiment according to the present invention is a non-breathable plate 10 is divided into a space portion of the front (16) and the rear (17) by inserting a member 22 formed with a hollow cushioning projection formed in the space is integrated The sole is shown as an embodiment, but the size of the foam layer cushion protrusion 33 is 5% to 10% higher than the cushion protrusion upper surface 21 as described above.

5 is a perspective view and a cross-sectional view showing that the space portion of the non-breathable plate 10 is divided into the front 16a and the rear 17a as another embodiment of the present invention.

6 and 7 show the through-hole 18 by forming the through hole 18 in the non-breathable plate 21 according to the present invention so as to face the through hole 18 and the hollow cushion protrusion protrusion 22a. ) Is combined with another non-breathable plate 19 attached to the bottom of the cushioning plate (22a) so that the inside of the cushioning projection (22a) is a sealed space so that it is not easily recessed even if the continuous compression and restoration is made.

The upper surface of the cushion protrusion protrusion 22a of the completed sole protrudes inside the shoe to evenly support the sole surface, thereby inducing propulsion by shock absorption and rebound elasticity, and the acupressure effect of the sole massage by the vertical flow of the cushion protrusion. .

On the other hand, the embodiment of Figure 6 or 7 can also be said to be a technology that can be applied to acupressure slippers, sports sandals, etc. when the bottom surface 100 is made of a rubber material.

8 is a hollow cushioning projection 25a in the space portions 51 and 52 by separating the front space portion 51 and the rear space portion 52 to the non-breathable plate 50 as another embodiment according to the present invention. 25b shows the attached outsole in which the hollow cushioning projection 33 is incorporated by engaging the member and attaching another non-breathable plate 19 to the upper surface.

FIG. 9 shows another embodiment of the present invention in which the hollow cushioning projection 25a member is built only in the front portion 51a, which is applicable to men's shoes and women's high heels as described above. In particular, shoes with a high heel will have the effect of supporting the foot comfortably when the center of the sole's weight is moved forward.

Figure 10 as another embodiment according to the present invention shows the state of the hollow cushion projection attached to the fabric fabric combined with the upper end of the embodiment as an example that the application range for insoles, midsoles, etc. is considerably wide Can be.

1, 2, and 8 are applicable to insoles, but the upper edge of the upper 60 and the edge of the non-breathable sheet 10 that are expanded and expanded as shown in FIG. 10. It has no problem in exerting shock absorption and rebound elasticity when sewing the edge and sewing, and it helps to improve productivity and reduce cost while saving the existing fabric.

Another advantage is that the expansion-expanded hollow cushion projection 33 is mounted only on the cushion projection 23 may have advantages such as material saving and weight of the elastic material.

And as shown in Figure 10 when the structure is made of a variety of separate insoles and midsole is also an advantage that is omitted.

11 is another embodiment according to the present invention, the hollow cushioning projections are made of a transparent material on the bottom surface of the outsole 700 hollow hollow cushioning projections 25, 27, 27a is exposed to the outside to the inside of the shoe Hollow cushion protrusion 33 is built-in for the purpose of visually confirm that there is a function due to shock absorption and rebound elasticity, and also cushioning through a transparent plate (not shown) to the outsole 700 side May be identified. At this time, there is also an effect that can further increase the product value by applying a color to the foam layer cushion projection (33).
