Description

Functional inner sole for shoes which having coconut fiber}

The present invention relates to a shoe insole, and more specifically, by using a coconut fiber having a functional property such as breathability and moisture absorption, without the adhesive to increase the required performance without increasing the performance of the coconut fiber To functional shoe insoles contained.

In general, insoles, especially sneakers and the like, are provided with a shoe insole made of a soft cushioning member for improved fit. These shoe insoles are usually made of the shape of the sole surface in the shoe is made of a cushion material to feel the comfort of the wearer and to lift the fatigue.

However, in the case of shoes such as sneakers, the cushioning material itself is warm, so when wearing these shoes, not only heat is generated inside the shoes when walking, but also such heat is not discharged to the outside, and it is combined with sweat generated by heat. If you take off your shoes, there are a lot of smells. In addition, there is a problem that such a smell becomes a habitat of the pathogen when left in the shoe as it is, causing side effects such as athlete's foot.

Therefore, many different kinds of insoles have been developed to solve this problem. Representative examples are insoles manufactured by adding minerals such as ocher and ceramics to remove odors.

On the contrary, in recent years, attempts have been made to solve problems by using different insole materials.

According to Utility Model Registration No. 221861, a shoe insole made of coconut fiber excellent in sweat absorption, breathability, and deodorizing effect is disclosed. As shown in FIG. 1, the fiber fabric 2 is adhered to one side of the coconut fiber disc 1 made of a thin thickness with an adhesive to form a flat plate press-cut to have a bottom shape inside a shoe. .

Shoe insoles manufactured as described above are absorbed and ventilated due to the nature of the material, while the thickness is too thick to put on the sole of the shoe is not only inconvenient to fit, but also has a disadvantage that the fit is reduced during walking There is a problem of feeling tired.

On the contrary, according to the Utility Model Registration No. 321708, in order to solve the above problems, it has a general shoe insole form. That is, as shown in Figure 2, the fiber fabric 20 is glued by the adhesive on the upper surface of the coconut fiber 10, a plurality of vent holes 31 so that air can be circulated on the bottom surface of the heel Cushion member 30 having a) is also combined with the adhesive to form a thermocompression bonding. On the other hand, the central portion is formed with acupressure protrusions 40 is drawn upward.

The above design has improved the fit of the general shoe insole form, and excellent moisture absorption and breathability due to the characteristics of the coconut fiber has the following problems.

Since the adhesive is used for the combination of the coconut fiber and the fiber fabric, there is a problem in that it does not fully exhibit the function of the coconut fiber itself. That is, when it is described in more detail, when the adhesive is applied to the upper surface of the coconut fiber, an adhesive film is formed on the fibrous surface to form a kind of coating. Therefore, a fundamental problem occurs that the fiber function of the coconut fiber itself is degraded by the adhesive film.

In addition, a separate cushion member on the heel portion is also combined with an adhesive, which not only has the same problem, but also increases the manufacturing cost by using a separate cushion member.

And most of all, in order to manufacture the shoe insole as described above after the cutting in the state in which the coconut fiber, the fiber fabric and the cushion member are combined, the thermocompression molding process is made so much material loss. Therefore, the coconut fiber itself is expensive, there is a problem that the manufacturing cost of the shoe insole increases.

Therefore, the present invention has been devised to solve the problems of the above-described prior art, but using a coconut fiber having excellent performance, by maintaining an inherent function of the coconut fiber as it is without using an adhesive to maintain high functionality as it is The purpose is to provide a shoe insole.

In addition, there is another object to minimize the material loss of the expensive coconut fiber when manufacturing the shoe insoles, and to make the manufacturing cost of the shoe insoles by making a simple method.

There is a technical point in providing this. And, preferably, the fiber fabric, the upper fiber fabric which is covered on the ethyl vinyl acetate window and the upper surface of the coconut fiber, the coconut fiber is bonded by sewing; The lower fiber fabric is attached to the bottom surface by sewing the coconut fiber is located; and the coconut fiber formed on the side border surface is added to the fiber fiber is added to make the encapsulation. In addition, a plurality of coupling holes are formed in the coconut fiber, and a portion of the ethyl vinyl acetate is inserted into the coupling hole so that the coupling is made, or a separate ethyl vinyl acetate is added to the bottom of the coconut fiber. To be combined.

Therefore, there is an advantage that the adhesive is not applied to the upper surface of the coconut fiber can maintain its original function.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the main purpose is to use coconut fiber as an insole without adhesive. Therefore, various configurations are possible, and will be described below through each embodiment.

First embodiment

As shown in Fig. 3, in the present invention, it is made up of large parts. First, the most important role of the shoe insole 100 and the material forming the sole shape is to be made of ethylene vinyl acetate 110 (E.V.A briefly referred to as Yves). Since the Yves 110 material is made of an elastic material as well as ease of processing, it is commonly used as a shoe insole material. However, the present invention does not use this form as a simple Eve, but is limited to use.

That is, in the present invention, the main purpose is to use the coconut fiber 120 material to maintain the functionality, such as breathability, hygroscopicity. Therefore, the processing is made in advance in the portion where the coconut fiber 120 material is located. For this processing, a portion of the coconut fiber 120 is to be placed in advance so that an empty space is formed. Then, the fiber fabric 130 is coupled to the upper surface of the Y-110 material provided with the coconut fiber 120. Coupling with such a fiber fabric 130 is to be made in duplicate. That is, the fiber fabric 130 in contact with the pure YB 110 surface is made to be bonded with a conventional adhesive, and the fiber fabric 130 combined with the coconut fiber 120 is in the sewing process without a separate adhesive treatment Thread stitching by 122 is to be made. Therefore, since a separate adhesive treatment is not performed on the coconut fiber 120, the coconut fiber 120 can maintain functions such as air permeability and hygroscopicity.

On the other hand, it is also possible to use it as it is, but it is also preferable to add a separate fiber fabric 130 'to the bottom. The reason for this is to prevent such a point because the foreign matter is changed to the bottom surface of the exposed coconut fiber 120, the functionality may decrease with time. Therefore, as the fiber fabric 130 'is added to the back of the portion where the coconut fiber is combined, foreign matters can be prevented from being attached, and the fiber fabric 130' itself has ventilation so that comfortable use can be made possible. In addition, since the expensive coconut fiber 120 can be used only in the necessary portion, it is possible to produce insoles at low cost because no extra waste is generated.

Next, the manufacturing process of the shoe insole is configured as described above.

First, to prepare a plate-shaped Eve of the appropriate thickness used as the insole 100 material. The Yves material 110 is prepared by cutting the Yves to the size of the overall shape. Of course, by cutting off the portion where the coconut fiber 120 is to be inserted, such as cutting, the Yves material 110 is prepared. Place the coconut fiber 120 prepared separately in the empty space of the Yves 110. At this time, the coconut fiber 120 is also prepared in advance cut to the size to be inserted separately in advance.

Then, a separate adhesive treatment is made on the upper surface of the Yves 110. This adhesive is to be applied only to the pure Yves 110, the upper surface, and of course not to be applied to the inserted coconut fiber 120 upper surface.

In the above state, the fiber fabric 130 is placed on the upper surface of the Y-110 and the coconut fiber 120. At this time, the pure YB 110 and the fiber fabric 130 is to be bonded by the mediated by the adhesive, the coupling of the coconut fiber 120 and the fiber fabric 130 is thread coupling by sewing machine 122 ). As described above, in order to maintain the function of the coconut fiber 120 to the maximum, it is preferable that the adhesive treatment is not made. And, the coupling is to be made so that the coupling is made to the thread 122 by sewing machine processing.

As described above, after all the materials are combined, the post-processing process is performed using a mold so that the shape of the shoe insole 100 is achieved. This post-processing process is made in the same manner as the conventional insole manufacturing process, detailed description thereof will be omitted.

Second embodiment

Next will be described another embodiment according to the present invention.

As shown in FIG. 4, most of the bottom of the sole where the sole is located is made of coconut fiber 120 ', and the part covering the heel is made of Yves material 110'. By constructing as described above, it is easy to form a concave portion that can be wrapped around the heel of the Yves material 110 'good workability can be the most suitable shape of the shoe insole 100'. And, the coconut fiber 120 'is threaded coupling 122' by the sewing machine so that the coupling with the fiber fabric 130 'is configured as described above.

On the other hand, in the present embodiment, the front edge of the shoe insole (100 ') is added to a separate fabric fabric so that the side treatment (124') is made. The reason why the side treatment (124 ') is necessary is to prevent the loss of the coconut fiber (120'). That is, since the coconut fiber 120 'may be dropped from the edge of the shoe insole 100' during continuous use, the separate side treatment 124 'may be performed to prevent the coconut fiber 120' from falling off. do.

Third embodiment

In this embodiment, as shown in the first and second embodiments described above, the coupling of the coconut fibers is shown, not the binding by the sewing. As shown in Fig. 5, the configuration is largely composed of three. That is, Yves 200 is used as the basic insole material. The required portion of the Yves is carried out to form a hollow space 210 by plucking, and is configured so that the coconut fiber 300 is coupled to the empty space. The coconut fiber 300 is prepared separately to be the size of the empty space 210 in advance. Then, to prepare a separate attachment EVE 220 material on the lower surface of the coconut fiber coupled to the empty space. The attachment Y-220 material is prepared to be somewhat larger than the size of the coconut fiber, the hardness is lower than Yves (200) to prevent the coconut fiber from being separated to the outside as well as to play a cushion function. Make sure Then, the fiber fabric is covered on the upper surface of the coconut fiber 300 coupled to the empty space of the Yves 200.

Next, a manufacturing process according to the present embodiment configured as described above will be described. Coconut fiber 300 is placed in the empty space 210 of the Yves 200 where the picking is performed, and the Yves 220 for attachment are placed on the bottom surface thereof. Of course, at this time, the adhesive is applied to the upper surface of the Yves 200, the adhesive is not applied to the upper surface of the coconut fiber. The reason is that, as described above, when the adhesive is applied to the upper surface of the coconut fiber is reduced in its function to maintain the inherent function of the coconut fiber 300 to the maximum. In addition, the adhesive is applied to the surface of the Yves 220 is attached to the bottom of the coconut fiber is attached to the bottom of the Yves 200 to prevent the departure of the coconut fiber (300). The attachment electrode 220 is to cover the entire space to act as a partition so that the material in the space stays in the space so that the material itself can be a shock absorbing layer. Then, after placing the fiber fabric on the upper surface of the material prepared as described above, it is produced by placing in the mold in the same manner as the conventional insole manufacturing. When fabricating as described above, the existing insole material Yves 200 is used to produce a shape suitable for the soles, while the processability is the same as the conventional, while the coconut fiber 300 is located in the required area, its function is more It can be improved.

Fourth embodiment

In this embodiment, as shown in Fig. 6, Yves 200 'is used as a material for the basic insole shape. The Yves 200 'is not only available as a conventional general insole material, but can also be used in a perforated form as shown. As a matter of course, it is also possible to use a state in which a hole or a portion in which a coconut fiber to be described later is located is removed.

Then, to prepare the coconut fiber (300 ') to be formed smaller than the overall size of the Yves 200' and placed on the required portion. In the coconut fiber 300 ', a plurality of small coupling holes 310' are formed. The reason why the coupling hole 310 'is formed as described above is to facilitate coupling with the Yves 200'. That is, the key point of the present invention is to make it used without the adhesive is applied to the upper surface of the coconut fiber (300 '). The coupling hole 310 ′ is necessary to form a rigid bond without adhesive. As will be described later, the Yves 200 'material penetrates through the coupling holes, and thus the Yves 200', the coconut fiber 300 ', and the fiber fabric 400' can be firmly coupled. Further, the fiber fabric 400 'is positioned on the YB 200' and the coconut fiber 300 ', and the fiber fabric 400' is mentioned in the above-described embodiment, and thus a detailed description thereof will be omitted. do.

Next, the manufacturing process of the insole according to the present embodiment configured as described above will be described. First, Yves 200 'material is prepared. The adhesive is applied to the upper surface of the Yves 200 'material for bonding to the fiber fabric 400', which will be described later. Meanwhile, the coconut fiber 300 'having the coupling hole 310' is formed on the material of the Yves 200 '. Then, the fiber fabric 400 'is bonded to the material provided as described above, and the insole is manufactured by applying heat and cooling to the mold in the same manner as the conventional insole manufacturing.

On the other hand, the insole is manufactured in the same manner as in the prior art, but the coupling method forms a completely different configuration. That is, some of the Yves material expanded by the heat applied in the mold penetrates between the coconut fibers 200 'and the coupling holes 210', and the upper surface is adhered to the fiber original cross section. Since the insole is formed in the mold by the pressure and cooling applied in the above state, the bonding with the fiber fabric is made by the adhesive p applied to the upper surface of the Yves 200 'material and simultaneously Yves 200 A part of ') is coupled between the coupling holes 310' of the coconut fiber 300'to make the whole coupling. Therefore, no other joining means, that is, no post-processing, such as sewing as in the first and second embodiments, and can also achieve a firm coupling without a separate adhesive treatment on the upper surface of the coconut fiber (300 '), as it is a high function You can achieve a solid bond while maintaining.

The present invention configured as described above, since the coconut fiber is a component of the shoe insole without a separate adhesive treatment has the effect of maintaining a high functionality.

In addition, there is another effect that the manufacturing cost is low because the shoe insole is achieved by cutting only necessary parts without extra loss of coconut fiber, which is an expensive material.

In addition, there is another effect that the proper shape of the shoe insole can be easily made by using Yves material with good processability.
