Abstract

PURPOSE:To realize the formation of the insole, the shape of which exactly conforms to the unevenness of the sole of the foot of a user by a method wherein supple material having a very weak restoring force is employed so as to faithfully transfer the shape of the depression of a footmark to mold material by treading on the matter with the feet in order to utilize the treaded matter as it is as a mold. CONSTITUTION:In a container-like form 2, first liquid resin for base material for forming supple polymer viscoelastic body, which restores very solowly, is cast. By the equally standing of the user of insole on rubbery sheet 5, with which the base material 4 consisting of the gelled polymer viscoelastic body is covered, with his two feet 6, a footmark depression 5a together with the deformation of the base material on the rubbery sheet. A second mold is formed by casting quick-curing second liquid resin on the resultant first mold 1 consisting of the base material and the rubbery sheet. Next, the insoles of both the feet are extracted by trimming from the sock lining material after the curing of the second liquid resin cast on the second mold, which is turned upside down and placed onto the bottom of another form.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an insole that matches a user's foot.

[0002]

2. Description of the Related Art Insoles are used in a variety of forms such as leather, synthetic resin, vegetable fiber, or a composite structure of these, so that the feet are in close contact with the shoe and are comfortable to wear. In addition, a variety of deodorant insoles containing activated carbon and shiatsu insoles provided with protrusions for pressing the soles of the feet are also available.

Regarding the shape, it is formed flat so as to fit the sole of the shoe, and is divided into several sizes, which are selected and worn. If an insole that fits the user's foot is to be made, a foot mold is also required, and it will take time and money. Therefore, the insole that fits the user's foot is actually used. It was never done.

[0004]

[Problems to be Solved by the Invention] The conventional insole is
As it has a flat shape as described above, wearing it can achieve its purpose to some extent when it fits the size of the foot, but even if it fits, it is a flat shape for each size. However, there is a problem in that the weight of the body is not evenly applied to the sole of the foot, and wearing the shoes becomes uncomfortable or tired, which causes various obstacles to the body.

The fact that the physical disorder occurs is because there is a starting point of a path related to all the organs of the body on the sole of the foot. For example, the big toe gives control to the liver and muscles. The spleen and liver, the index finger has a stomach point, and the ring finger has a starting point for the gallbladder that controls the gallbladder. When the foot is pressed by the insole, this important blood flow tends to be delayed.

The present invention has been made in view of the above circumstances.
(EN) A method for manufacturing an insole capable of easily and inexpensively producing an insole that conforms to the sole of a user so that the entire weight of the body is evenly distributed and hung on the entire sole. Intended.

[0007]

In order to achieve the above-mentioned object, the present invention provides a first base material for forming a soft polymer viscoelastic body on a container-shaped mold, which is very slow in restoring. By pouring the liquid resin of, the rubber-like sheet is covered on the base material made of a gelled polymer viscoelastic body, and the user of the insole stands evenly with two feet on the rubber-like sheet,
The sole mold is formed on the rubber-like sheet with the deformation of the base material, and the second mold is formed by pouring the second liquid resin which is fast-curing onto the first mold consisting of the base material and the rubber-like sheet. Form it, then put the second mold inside out on the bottom of another mold, pour the second liquid resin above the second mold, and trim from the insole material formed by hardening the resin. The present invention provides a method for manufacturing an insole of a shoe, wherein the insole of both feet is removed.

If the first liquid resin for the base material is a bisphenol F type epoxy resin as a main component, a curing agent is mixed therein, and the mixed solution is heated to gel.
It is effective in achieving the above purpose.

[0009]

[Working] Since the method of manufacturing the insole is configured as described above, so that the total weight of the user is evenly distributed over the sole of the foot, the shape of the insole is the recessed shape with the sole reversed. It is characterized in that it is easy to manufacture the first and second molds necessary for manufacturing the insole, and that it can be reused. Explaining the first type, a soft polymer viscoelastic material that restores very slowly is used for the base material, and the depression of the footprint is transferred to the shape material according to the shape by stepping on it with the foot, and it can be used as it is as the sole type It is easy and, moreover, it can be reused as a mold many times because the dents in the footprints are restored to their original state with time after being used as a mold.

The base material is, for example, 200 parts of a mixed solution prepared by mixing the main component and the curing agent in a weight ratio of 100 parts to 85 parts.
A gel viscoelastic material that is heated at ℃ for about 1 hour and gelled. In this case, it takes about 2 hours to recover the original shape from the state of being depressed from the outside and returning to its original shape. In order to retain the above-mentioned property, the sole mold is transferred to the second mold by the second liquid resin which is fast-curing within the time required for this recovery. Further, the gelled substance as the base material has strong adhesiveness on the surface and cannot be directly stepped on, but it is also characterized in that it is solved by covering the surface with a rubber-like sheet.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.

1) Manufacture of the first mold 1 The first mold 1 is composed of a base material 4 and a rubber-like sheet 5 (FIG. 4), and as shown in FIG. A box-shaped or container-shaped mold 2 having the above is used. Regarding the size of the formwork 2, for example, the wall thickness is 1
The length is 0 mm, and the inner dimensions are 30 cm in length, 40 cm in width, and 10 cm in height, and are assembled in a square box shape. Wood, plastic, metal, etc. are used as the material.

The mold 2 is filled with a mixed liquid 4a (first liquid resin) of 100 parts by weight of the main agent and 85 parts by weight of the curing agent in a weight ratio up to about 8 minutes of the capacity of the mold 2, and then 200 Base material 4 by heating for about 1 hour at ℃ and gelling
And the surface is covered with the rubber-like sheet 5. The rubber-like sheet 5 is preferably a rubber-like sheet whose elastic deformation is particularly slow to be restored. For example, a silicon rubber sheet or a neoprene rubber sheet having a thickness of 0.5 mm or less is used. Then, as shown in FIG. 3, the user of the insole is made to stand with both feet 6, 6 on the mold material to form a sole mold 5a as shown in FIGS. 4 and 5.

The first liquid resin 4a for the base material 4 described above.
A bisphenol F type epoxy resin can be effectively used as the main component of the. Further, as the curing agent, for example, polytetramethylene oxide P aminobenzoate is used. When this mixed solution is gelled by heating, it becomes a soft polymer viscoelastic body. As described above, if the foot is directly placed on this, the foot adheres to it. However, since the foot is placed on the rubber-like sheet 5, such an inconvenience is eliminated, and the rubber-like sheet 5 is covered with the base material 4. Foot sole type 5a with deformation
Is stably formed.

2) Manufacture of the second mold 8 Since the shape of the sole mold 5a thus formed on the rubber-like sheet 5 is slow to restore, as it is, the shape of the sole mold 5a before restoring the shape is as shown in FIG. Then, the second liquid resin 7 which is fast-curing is poured into the sole mold 5a on the sole mold 5a. This second
As the material of the liquid resin 7 of, for example, UV curable resin (ultraviolet curable resin: acrylic resin or the like) is used. In this case, if a curing condition of 631 nm wavelength is applied for curing, a thick film product of 10 to 30 mm can be molded within 30 seconds. When silicone rubber is used, it cures within 20 minutes at a curing condition of 80 ° C.

3) Manufacture of insole material 11 On the rubber-like sheet 5, the sole mold 5 is thus formed.
When the second die 8 to which a is transferred is manufactured, next, as shown in FIG.
As shown in FIG. 8, the second mold 8 is peeled off from the mold 2, and the second mold 8 is laid on the bottom of a separate mold 9 as shown in FIG. The mold 9 has a thickness of 10 mm, for example.
A square-shaped box made of aluminum with a 30 cm length, 40 cm width, and 10 cm height is used. The second liquid resin 10 is poured into the second mold 8 by the container 3. For this, the above-mentioned UV curable resin or silicone rubber can be used.

4) Manufacture of insole S At the bottom of the mold 9, in this way, when the second mold 8 forms the insole material 11 in which the second liquid resin 10 is cured,
The target insole S is manufactured by peeling it off as shown in FIG. 9 and cutting it with scissors 12 etc. as shown in FIG.

[0018]

As described above, according to the present invention, a soft material having a very slow restoring force is used, and by stepping on it with a foot, the depression of the footprint is transferred to the shape material as it is, and as it is. Since it is used as a mold, not only can the insole be formed into a shape that accurately matches the irregularities of the sole of the user's foot, but it is also easy to manufacture and can be completed in a short time. In addition, after using it as a mold, the depressions of the footprints will return to their original state over time and can be reused as a mold material many times, so it is economical and it is possible to provide such a special insole at low cost. It has an excellent effect, and by wearing it, the force applied to the sole of the foot is evenly distributed throughout the body, so local foot fatigue and impact are mitigated, and even if you wear it for a long time, you will not get tired It is also suitable for improving health.

Further, since the sole of the foot is accurately transferred, by providing the projection partially, it is also suitable for manufacturing an insole for acupressure shoes that exactly matches the acupoint on the sole of the user's foot.
