Description

  The present invention relates to an insole for a shoe that fits very well to a foot of a user who wears the shoe, and a manufacturing method thereof.

  Shoe insoles have been used in the past to improve the comfort and feeling of use of the shoes or to obtain effects such as deodorization. However, since the shape of human feet varies, commercially available insole Therefore, it is difficult to completely fit the foot of the user who wears the shoe. For this reason, there is a custom-made insole that matches the shape of the user's foot, but custom-made is expensive and it is generally not used because it takes time to complete.

  In addition, as a method of manufacturing a shoe insole that can easily and inexpensively make a shoe insole that matches a user's foot, a method described in Japanese Patent Application Laid-Open No. 7-314582 is disclosed. As in the “Manufacturing method”, a rubber-like sheet is placed on a base material made of a polymer viscoelastic body made of a liquid resin, and the user stands evenly on the rubber-like sheet with two feet to form a rubber-like sheet. A first mold which is a sole mold accompanied by deformation of the base material is formed, and a second mold is formed by pouring a fast-curing liquid resin on the mold, and the second mold is formed on the bottom of another mold. An insole manufacturing method characterized in that the two molds are placed inside out, the liquid resin is poured onto the second mold, and the insole of both feet is extracted from the insole material formed by curing the liquid resin by trimming. Yes.

However, the “shoe insole manufacturing method” according to the present invention is a conventional method because the insole material is extracted using the second mold after forming the first mold and the second mold using another type of liquid resin. Although it can be easily manufactured at a low cost compared to a custom-made method, it is difficult to manufacture easily even in ordinary households.

  Then, this invention aims at providing the insole for shoes which can be manufactured cheaply and easily also in a general household, and its manufacturing method by using a commercially available wrap film, a silicone resin, and a mount as a material. It is.

  In order to solve the above-mentioned problems, the present invention provides a shoe insole on an insole material in which a mount is laid on the bottom of a formwork, a silicone resin is applied thereon, and the surface of the silicone resin is covered with a wrap film. The user can stand with bare feet, apply force to take the mold of the sole, and after the silicone resin of the insole material has hardened, cut the insole material on which the sole mold is formed according to the shoe with scissors A shoe insole characterized by completion and a method for manufacturing the insole.

  According to the present invention, since the insole for shoes can be manufactured using a commercially available material, it is possible to easily manufacture the insole for shoes even in general households.

  The insole for shoes according to the present invention can be manufactured to match the shape of the sole of the user, so it fits perfectly to the sole of the user, and fatigue even when walking or standing for a long time. light.

  It is also possible to manufacture and use an insole for correcting the crotch, hallux valgus, toe alignment, etc., by adjusting the force at the time of taking the mold and changing the angle at which the force is applied.

  Below, the insole for shoes which is this invention, and its manufacturing method are demonstrated in detail based on an accompanying drawing. FIG. 1 to FIG. 5 are diagrams showing manufacturing steps of a method for manufacturing a shoe insole according to the present invention.

  FIG. 1 is a cross-sectional view showing a first step of a method for manufacturing a shoe insole according to the present invention. As shown in FIG. 1, the first step 1 of the method for manufacturing a shoe insole is a step of preparing an insole material that is a material for the insole.

  In the first step 1 of the method for producing an insole for shoes according to the present invention, a mount 1b having a thickness of about 0.5 mm is laid on the bottom of the mold 1a, and a commercially available product having a thickness of about 7 mm is placed on the mount. By applying the silicone resin 1c and covering the surface of the silicone resin with a commercially available wrap film 1d, preparation of the insole material is completed.

  The formwork used here is to prevent the silicone resin 1c from flowing out from the mount 1b, and is a container having a flat bottom, a width of about 15 cm, and a length of about 23 cm to 28 cm. Wooden, paper, plastic, etc. are not limited.

  FIG. 2 is a sectional view showing a second step of the method for manufacturing a shoe insole according to the present invention, and FIG. 3 is a plan view of the second step of the method for manufacturing a shoe insole according to the present invention. As shown in FIG. 2, the 2nd process 2 is a process of taking the type | mold of a user's sole. In the second step 2, the user stands barefoot on the insole material prepared in the first step 1 of FIG. 1, and the toe 3a and the heel 3b of the user's foot 3 are laid on the bottom surface of the mold 1a. Apply force to the point where you touch 1b and take the sole mold.

  In the second step 2, as shown in FIG. 3, by properly aligning the toes 3d and applying a force evenly from above, it is possible to take a mold that exactly matches the shape of the sole.

  As shown in FIGS. 2 and 3, since the insole material has the surface of the silicone resin 1c covered with the wrap film 1d, the mold can be taken without the silicone resin 1c sticking to the sole.

  FIG. 4 is a plan view showing a third step of the method for manufacturing a shoe insole according to the present invention. As shown in FIG. 4, the third step 4 is a step of forming the sole mold 5 on the insole material composed of the mount 1b, the silicone resin 1c, and the wrap film 1d.

  The silicone resin 1c used for the insole material hardens in about 24 hours without returning to the original mold of the sole applied in the second step 2. That is, a sole mold 5 having irregularities such as a toe portion 5a, a heel portion 5b, and an arch portion 5c is formed in the mold 1a.

  FIG. 5 is a plan view of an insole manufactured by the method of manufacturing an insole according to the present invention. In the third step 4 of the method for manufacturing a shoe insole according to the present invention shown in FIG. 4, the insole material in which the silicone resin 1c is hardened and the sole mold 5 is formed is taken out from the mold frame 1a, and the foot is matched with the shape of the shoe. The insole 6 is completed by cutting the back mold 5.

  The entire shape of the insole 6 may be cut out from the insole material along the shoe mold 6a that matches the shape of the shoe using the insole.

  The insole 6 shown in FIG. 5 manufactured through each of the first step 1 to the third step 4 shown in FIGS. 1 to 4 matches the shape of the sole of the user's foot 3. Therefore, when the insole 6 according to the present invention is used for a shoe, it fits snugly on the sole and the comfort is remarkably improved.

  Further, in the step of taking the mold of the second step 2 shown in FIG. 2 and FIG. 3, if the mold is taken with the center of gravity placed on the arch 3c side of the foot 3 so as to be a slightly inner crotch, the crotch is corrected. The insole 6 can be formed, and the insole 6 for correcting the hallux valgus can be formed by properly aligning the toes 3d and taking a mold, and thus can be applied to the production of an insole capable of obtaining a wide range of effects.
