Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to novel footwear that utilizes far infrared rays emitted from ceramic paper.

(Conventional technology and its problems) It has been experienced that ordinary shoes, including men's shoes and women's shoes currently on the market, can cause toes to freeze in the middle of winter, causing chilblains or, in severe cases, frostbite. Especially in the case of men's shoes, it has been experienced that the inside becomes stuffy, causing discomfort and a bad odor. In addition, special shoes with a heat-retaining structure are used when working in large commercial freezers for long periods of time, or when climbing or skiing in the harsh winter months, but as mentioned above, these shoes have a certain amount of thickness due to their heat-retaining structure. As a result, the shape of the shoe inevitably became large, making it difficult to handle, and being heavy and not very comfortable to wear.

The present invention was developed in consideration of such conventional examples and experiences, and its purpose is to use far infrared rays to actively warm the feet instead of keeping them warm. To provide footwear using far infrared rays, which does not change the shape of the footwear or can be made smaller, has heat insulating and moisture absorbing effects, and prevents the inside of the shoe from getting stuffy in the summer.

(Means for solving the problem) In order to solve the problems of the conventional example, the present invention has a structure in which "ceramic paper 4 that emits far infrared rays at room temperature is attached to the inner peripheral surface of the footwear". is adopted.

(Function) By pasting the ceramic paper 4 that emits far infrared rays at room temperature on the inner peripheral surface of the footwear, when the shoes are worn, the feet are constantly warmed by the far infrared rays radiated from the ceramic paper 4.

Ordinary men's and women's shoes do not suffer from frostbite or frostbite even in the harshest of winters.

In the case of special shoes such as ski boots and work boots for the freezer, the heat insulating layer can be made thinner, and the entire shoe can be made smaller.

The warming effect of far infrared rays has been known since ancient times in Oriental medicine to stimulate the reflex points on the soles of the feet, strengthen the organs connected to the reflex points, and eliminate physical ailments without you even realizing it. You can spend every day comfortably.

(Example) Hereinafter, the present invention will be described in detail according to the illustrated example.
Footwear includes chemical shoes such as men's and women's shoes, slippers, sandals, rain boots, mountain climbing shoes, special shoes for sports such as baseball, rugby, and golf, special shoes for work such as those for freezers, and shoes for hospitals and medical institutions. There are special footwear. This generally includes an insole material 2, leather 8 (or upper leather), outsole 7, etc. Here, we will mainly explain men's shoes or women's shoes.

The ceramic paper 4 is composed of an extremely thin nonwoven fabric 5 made of high-purity, highly heat-resistant alumina-silica fiber and a binder, and a plastic sheet 6 attached to both sides of the nonwoven fabric. is approximately 0.3 mm in this embodiment. Of course,
The thickness may be greater or less than this as required. Alumina is a very hard (Vickers hardness 2800) granular or crystalline material with the chemical formula Al ₂ O ₃ , and silica has the chemical formula SiO ₂ ,
It is a colorless and transparent crystal and is known as a raw material for glass and ceramics, and these fibrous substances are used in this example. This ceramic paper 4 always emits far infrared rays at room temperature. Far-infrared rays are efficiently absorbed by materials due to the resonance resonance phenomenon, and have the function of warming and heating the irradiated materials.

Materials for the midsole material 2 include pressboard, various leather boards (synthetic leather), genuine cowhide leather, resin-based raw material boards, rubber midsole (hub), and materials similar to toppings.

Now, for the insole material 2, how to assemble the material, and
Depending on the material and how it is used, it is classified into a material for the inner sole with a shank 2 and a material for the inner sole without a shank 2, which will be explained below.

(A) There are the following three types of insole materials 2 with shank. (In this case, gauze, that is, cheesecloth is attached to the back side of the insole material 2.) The insole material 2 is cut from a single piece of pressboard.

Insole material 2 assembled and cut by combining press boards.

Insole material 2 is made by combining press boards and cutting the assembled material with fabric, vinyl, and sponge.

(B) There are the following five materials for the insole without shank 2.

Insole material 2 cut from a single piece of pressboard.

Insole material 2 cut from various leather boards (synthetic leather).

Insole material 2 cut from genuine cowhide leather (However, in this case, there is also a version with a shank.) Insole material 2 cut from resin-based raw material board.

There are a rubber insole (hub), a material 2 for the insole cut from something similar to toppings, and the like.

In the case of (B), it can be used as is, but instead of the shank 3, an auxiliary material with a width larger than the shank 3 and a somewhat longer shape of about 1.2 to 1.5 times, which has elasticity and flexibility, is used. 20 may be pasted together. This auxiliary material 20 is as shown in Fig. 20,
Its thickness is 0.8 to 2.5 mm, and the other end 2R is narrower than the one end 2r or the same. Apply latex adhesive to the back side and stick.

Next, the substrate 1 for the insole of shoes includes a single piece of various materials, a basic type of press board, a composite type, and the like.
The basic type midsole substrate 1a is made by bonding a sieved portion of a piece 13 (heel material) with a thickness of about 1.3 to 4 mm to a sieved portion of a midsole 12 with a thickness of about 1.3 to 2 mm. The composite type insole substrate 1b is made by laminating a composite material 15 at a predetermined position on the basic type insole substrate 1a. 13 is pasted on the middle fabric 12 of a single piece, and then the single fabric 1
There are various types such as one in which composite material 15 is laminated on top of 3, and each can be used depending on the purpose. The aforementioned ceramic paper 4 is adhered to the surface of the midsole 12 of the midsole substrate 1, and furthermore, the midsole sheet 14 is pasted thereon. The inner sole sheet 14 may be made of, for example, gauze, a vinyl sheet, a woven fabric such as cheesecloth, or a non-woven fabric 5 such as felt.
and so on. The midsole material 2 is formed by punching out the midsole substrate 1, and at this time, the above-mentioned ceramic paper 4 is positioned at the toe area as shown in FIGS. 14 and 15. Incidentally, the shank 3 is fixed to or embedded in the back surface or inside of the inner sole material 2. Figures 7a, c, and d show the punched state and the punched inner sole material 2. Also, the seventh
Figures b, e, and f are examples of a material 2 for an insole made by pasting ceramic paper 4 on a single piece of press board and punching it out. Figures 8a to 8f show examples of the use of single-piece toppings, in which ceramic paper 4 is attached to the toe or the entire surface.

Next, the properties that the insole material 2 should have will be explained.

Good ventilation.

Good flexibility.

Good moisture absorption.

Good elasticity.

These properties are strictly required for high-quality shoes.

Next, shank 3 will be explained. Shank 3 is for giving elasticity to the sole of the shoe, and is the 9th shank.
It has a shape as shown in Figures a to 13b,
It is made by punching a steel plate into a rectangular shape by press working. Shayank 3 is classified into men's shoes, women's shoes, sandals, rain boots, and special sports shoes (climbing shoes, various spikes, etc.) based on its purpose.
The material, shape, and presence or absence of hardening of the shank 3 are determined depending on the application. Further, in order to stimulate the soles of the feet, the shank 3 may be magnetized or a magnetic rubber sheet 3a may be attached. Men's shoes should be magnetized at 610-680 Gauss, and women's shoes should be magnetized at 620-710 Gauss. In addition, a magnet rubber sheet 3a, which will be described later, is embedded as a shank 3 in the topping sole and the one-piece shank-less midsole material 2. Furthermore, for footwear that is difficult to embed, such as the shank 3, it is also possible to attach it to the outsole 7, toe area, or inner surface of the upper. The magnetic poles of the magnetized shank 3 or the magnetic rubber sheet 3a are provided in an odd number, and strong lines of magnetic force are generated on the inner sole side, and almost no lines of magnetic force are generated on the outsole 7 side.
This prevents the iron sand from the road from becoming magnetically attached to the soles of the shoes.

Incidentally, the magnetic rubber sheet 3a may be attached to or buried in the entire outsole 7 or the toe portion.

Next, a method for manufacturing shoes according to the present invention will be explained. First, the insole material 2 with the ceramic paper 4 incorporated therein is nailed to the bottom of a shoe mold (including a plastic mold) to which the leather 8 (or upper) is not attached. Next, the leather 8 is manually
After covering the leather (or the upper skin) and hanging it, use a finishing machine to hang the leather 8 (or the upper skin),
After performing the final tightening and inspecting the finished state, adhesive glue (for example, latex adhesive) is applied to the lower surface of the insole material 2, and then it is placed in a dryer to dry. Next, the main sole 7 is placed under the inner sole material 2.
Attach the bottom (bottom attachment work), use a bottom crimping machine to firmly adhere the outsole 7, cut out the mold, and then nail the bottom.
As a finished product.

The above example shows an example in which the ceramic paper 4 is attached to the toe portion, but of course the ceramic paper 4 is not limited to this, and the ceramic paper 4 may be attached to the upper part or the entire midsole. Further, in the case of special shoes such as ski boots and work shoes for freezers, ceramic paper 4 is pasted on the entire inner circumferential surface of the shoes. As a result, the heat insulating layer of the special shoe can be made thinner, and the entire shoe can be made smaller.

When you wear shoes made in this way, your feet are constantly warmed by the far infrared rays emitted from the ceramic paper 4, and even in the harsh winter, frostbite and frostbite will not occur. The magnetic force and the warming effect of this far infrared rays have been known since ancient times in Oriental medicine to stimulate the reflex area 9 on the soles of the feet, strengthen the organs connected to the reflex area 9, and unknowingly improve the body's health. Eliminate discomfort. FIG. 1 shows an outline of the reflex areas 9 on the soles of the feet that are associated with various organs of the body. Also, Figure 2 shows the path of the human body and the acupuncture points 18.
A relationship diagram is shown. In the figure, the vertical double line is the meridian 10, the horizontal double line is the meridian 11, the thick solid line is the branch 17, and the connection point (the part surrounded by the broken line) is the pot 18.

In addition, in the summer, the ceramic paper 4 is in the form of a non-woven fabric 5, so it has a moisture absorption effect, and the high-quality insole material 2 has the properties originally possessed by the above-mentioned insole material 2, that is, good breathability, Due to its flexibility and moisture absorption, the inside of the shoe does not get stuffy and there is no discomfort.

<Experimental Example> Next, an experimental example regarding ceramic paper 4 will be shown. 16 is a temperature sensor, and 19 is a cover for blocking the influence of outside air. One of the women's shoes is a regular one without ceramic paper 4 attached, and the toe of the other women's shoe is covered with ceramic paper 4.
I used one with . As a result of measuring 20 times with different combinations of temperature sensor 16 and cover 19, and with time intervals, ceramic paper 4
The measured value was 1.2°C to 2.3°C higher for the shoes with the material attached. In addition, we asked six women to wear different combinations and measured the results for each, ranging from 3.8℃ to 4.4℃.
(up to 4.8℃) high values were measured.

(Effects) As mentioned above, in this invention, ceramic paper that emits far infrared rays at room temperature is attached to the inner surface of the footwear, so when worn, the feet are constantly exposed to the far infrared rays emitted from the ceramic paper. It is heated, and ordinary men's and women's shoes do not suffer from frostbite or frostbite even in the harshest of winters. Furthermore, in the case of special shoes such as ski boots and work shoes for the freezer, the heat insulating layer can be made thinner, and the entire shoe can be made smaller. Furthermore, the warming effect of far infrared rays stimulates the reflex points on the soles of the feet, which have been known in Oriental medicine since ancient times, and strengthens the organs connected to the reflex points, eliminating physical ailments without you even realizing it. It is something that allows you to do things and live comfortably every day.
