First, referring to FIG. 13, the shoe sole according to the present exemplary embodiment has a non-breathable coating film 320 coated to surround the entire outer surface of the hollow cushion protrusion 220 including the bottom of the middle cushion window 200. A non-breathable taxon 310 is further provided on the upper surface of the cushion window 200. In addition, the non-breathable taxon 310 has a cut surface 312 is formed, the deodorizing member 400 is further provided on the cut surface 312.

As shown in Figure 14 and 15, the shoe sole according to the present embodiment, the non-breathable coating film 320 is formed on the upper surface of the intermediate cushion window 200, the non-breathable coating film 320 to the upper surface The shoe sole is further provided with a breathable taxon 310.

In addition, the non-breathable taxon 310 has a cutting surface 312 is formed at the position where the hollow cushion projection 220 of the intermediate cushion window 200 is formed, the deodorizing member 400 on the cutting surface 312 ) Is inserted and installed.

Hereinafter, the deodorizing member 400 will be described.

The deodorizing member 400 may be provided with a hemp non-woven fabric 410 or a fiber plate 420 made of coconut shell.

First, the hemp nonwoven fabric 410 is a compressed hemp nonwoven fabric 410 having a breathability by using a needle punching machine by mixing and spun a synthetic fiber, such as polypropylene, polyester, and hemp fibers at a predetermined ratio, the dyeing first ) Is manufactured.

That is, the hemp nonwoven fabric 410 is composed of 10 to 20% by weight of polypropylene (Poly Proplene) fiber, 20 to 30% by weight of polyester (Poly Ester) fiber and 50 to 70% by weight of hemp fiber do. When synthetic fibers and hemp fibers are used in this way, all the parts of the nonwoven fabric to be produced are evenly mixed and thus the efficacy of the nonwoven fabric can be maintained semipermanently.

Here, the higher the content of hemp fiber can be exhibited the effect that hemp (잘) has better, but if the content exceeds the maximum value, the problem of the flexibility and elasticity of hemp fiber falls. In addition, when the nonwoven fabric is manufactured with the weight of the nonwoven fabric 50g / m 2 to 300g / m 2, the surface texture is smoothed and the performance is improved.

Accordingly, bacteria that can cause various foot skin diseases due to sweat or other secretions from the foot can be provided with a non-woven fabric for insoles that maintains excellent breathability and buffering property and also exhibits excellent deodorizing properties and maintains antimicrobial properties continuously. By removing the fungus or fungi can reduce foot odor or athlete's foot.

Next, the coconut fiber plate 420 will be described.

The coconut fibrous plate 420 is made of coconut fiber, and thus the means for collecting the fiber from the coconut shell are already known, so detailed description thereof will be omitted. The coconut fibrous sheet 420 is a plate formed by spraying the natural latex stock solution, and press-molding the entangled strands by heat press. Thus, by forming the coconut fibrous sheet 420 to be sized to be embedded in the incision surface 312 space of the non-breathable taxon 310, a sufficient void is formed between the tissues of the coconut fibrous sheet 420 to provide ventilation and cushioning. The power will be excellent.

The manufacturing process of attaching such a coconut fiber plate 420 to the intermediate cushion window 200 is as follows. First, an adhesive is applied to the upper surface of the cushion window sheet 210, which is coupled to the coconut fiber sheet 420 inserted into the cut surface 312 of the non-breathable taxon 310 and the non-breathable taxon 310. For After adhering the non-breathable taxon 310 to the upper surface of the cushion window sheet 210, the coconut fiber sheet 420 is coupled to the incision surface 312 to manufacture a shoe sole. At this time, the adhesive is to be used as a latex stock solution so that the adhesive performance by the homogeneous material and there is no phenomenon of being separated after the adhesion.

Therefore, since the hemp non-woven fabric 410 or coconut fiber plate 420 becomes a component of the sole, there is an effect that can maintain a high functionality. In addition, when the multilayer structure is formed in multiple layers, it will have various designs and cushioning power.

Hereinafter, the working relationship of the present invention configured as described above with reference to Figures 1 to 15 as follows.

First, the working relationship of one embodiment of the present invention will be described with reference to FIGS. 1 to 5.

When the intermediate cushion window 200 is installed on the upper surface of the sole 100, a plurality of hollow cushion protrusions 220 and a middle partition wall 212 are inserted into the space 130.

At this time, as the upper surface of the space of the sole 100 and the bottom of the intermediate cushion window 200 are bonded, the space between the lower portion of the hollow cushion protrusion of the intermediate cushion window 200 and the space 130 is formed. The space is formed, and the partition wall 212 blocks the space 130 so that the space 130 is formed with two space portions, a front space portion and a rear space portion, which are partitioned back and forth.

In addition, as the hollow cushion protrusions 220 are formed downward at regular intervals between the plurality of hollow cushion protrusions 220, air passages through which air flows are formed between the hollow cushion protrusions 220 in the front and rear spaces.

In this state, when the user walks with the shoes produced using the present invention, the sole of the sole first starts the heel and walks while walking on the ground in the middle of the sole and the toe in order.

When walking like this, the rear edge portion of the heels, which first step on the ground, forms an inclined portion 14 to be inclined, so that the inclined portion 14 than the conventional angled heels stepping on the ground in line contact with the ground. When the surface is in contact with the ground contact is absorbed by the hollow cushion projections 220 inside the inclined surface and stable walking is started to be more effective to alleviate the shock transmitted to the heel.

When the foot heel stepped on the ground during walking, the intermediate cushion window 200 which is stepped on the heel of the foot is compressed, and the intermediate cushion window 200 is formed as a very soft foam layer material below and has a large number of hollow cushion protrusions having excellent cushioning ( As the 220 is formed, as the intermediate cushion window 200 is stepped on, pressure is evenly distributed to absorb shocks.

And, as described above, when the intermediate cushion window 200 is stepped on the inside of each hollow cushion projection 220, the air chamber 224 is formed so that air does not leak, each of the hollow cushion projections 220 is Like the rubber ball, the air is elastically compressed in the air chamber 224 to induce an air cushion action, so that the shock absorption effect is excellent.

In this way, if you lift the foot to the lower side, good cushion of the foam layer material itself to form the middle cushion window 200, and the restoring force of the hollow cushion protrusion 220 that the air compressed in the air chamber 224 is instantaneously restored. By the intermediate cushion window 200 is restored to its original position to provide a very soft and rhythmic grounding to the sole, such a grounding is to be repeated sequentially from the toe of the toe to the toe.

As described above, when the middle cushion window 200 is stepped on by the sole and repeats the lifting operation, an air pumping action is performed in the closed space formed between the lower portion of the middle cushion window 200 and the sole 100. Actively done

This is because when the rear of the foot stepped on the rear side of the intermediate cushion window 200, the air space which was filled in the rear space portion filled with the rear space portion formed on the rear side of the partition wall 212 momentarily contracted 214 By passing through the intermediate check valve (214a) to the front space portion corresponding to the front of the sole through the air volume of the front space portion is filled to the full amount of air is discharged into the shoe.

Subsequently, when the front side of the middle cushion window 200 is stepped on by the front part of the sole, which is the next operation, the air that has been filled in the front space while the lower front space part contracts is moved upward of the front side of the middle cushion window 200. Through the installed front check valve (216a) to be discharged to the front side of the sole to ventilate the front part of the sole is sweaty and humid much cold.

When the front part of the sole is stepped on the front side of the middle cushion window 200, the heel of the foot is lifted up, and the middle cushion window 200 of the rear side that was compressed by being stepped on the heel of the foot is expanded at the same time as the foot heel is lifted. The rear check valve 218a installed in the rear middle cushion window 200 sucks the outside air into the rear space portion to fill the rear space portion with air.

Since the three front and rear and intermediate check valves 214a, 216a, and 218a described above are designed to flow fluid only in one direction, the air in the rear space portion is moved to the front space portion as described above, and the air in the front space portion is It moves to the front part of the sole, and the outside air toward the rear axle is only introduced into the rear space.

According to the present invention, as described above, a space part completely sealed between the sole 100 and the intermediate cushion window 200 is formed, and the hollow cushion protrusion 220 made of a material having excellent cushioning is formed in the space. 6 to 12, the air chamber 224 formed in the hollow cushion protrusion 220 is provided with a non-breathable member 300 to prevent air from leaking. As it maintains a firm elasticity is always excellent cushioning and excellent pumping action.

Further, as shown in FIGS. 13 to 15, a deodorizing member 400, such as a hemp nonwoven fabric 410 or a coconut fiber plate 420, is further provided on the cut surface 312 of the non-breathable taxon 310 to provide excellent breathability. It also maintains buffering properties and exhibits excellent deodorizing properties. The antimicrobial properties can be maintained continuously, eliminating bacteria and fungi that cause various foot skin diseases caused by sweat or other secretions from the feet. Can be reduced.

Accordingly, it is possible to provide shoes that alleviate the shock transmitted to the body when walking or running for a long time to reduce the fatigue of the body, and always make the user's feet comfortable and comfortable.
