Description

[Detailed explanation of the idea] The present invention relates to a shoe insole that is formed to wrap around the instep.

Conventionally, this type of insole has been made of leather, synthetic fiber net, synthetic leather, etc. Shoes are also often made of synthetic leather or vinyl, and the soles of shoes are also made of synthetic products mainly made of rubber, including rubber soles. is often used.

That is, there is a remarkable tendency for shoes to be made of materials with particularly low breathability, and insole materials to be made of materials that have low moisture absorption.

Therefore, in the summer, your feet will sweat and feel uncomfortable, but in the winter, you will feel very cold.

Moreover, many socks are made of synthetic fibers, which exacerbates this problem.

This invention was developed after various researches in view of the drawbacks of the conventional methods.
We have learned that sweating water remains stuck on the epidermis of the feet, socks, or insoles, causing discomfort in the summer and a cold sensation in the winter.Based on this new knowledge, we have developed a new product. It is not only comfortable to use all year round, without the disadvantage of feeling uncomfortable in the summer or feeling cold in the winter, but it is also comfortable to use throughout the year, except for the soles of the feet, especially the stiffness of the feet (soil). It can give a gentle feel as if running on Tatami, a so-called crisp feeling.
The purpose of the present invention is to provide a useful insole that stimulates the soles of the feet to improve health and also provides durability.

To achieve this purpose, the main points of the shoe insole according to the present invention are: ``A base material made of a water-permeable and hygroscopic material made mainly of natural fibers, and a base material attached to the base material. Made of natural material with a hygroscopic wood core, it has hygroscopic properties.
In order to increase heat retention and provide a more comfortable feeling of use, these many wood cores are arranged with their longitudinal direction oriented in a direction that intersects the line connecting the base material's ankle and the toe. It is in the point set.

Next, an embodiment embodying the above-mentioned outline will be explained based on the drawings. In the figure, 1 is an insole base material, which is mainly made of natural fibers such as cardboard, nonwoven fabric, or rather thick woven fabric. It is made of a water-permeable or hygroscopic material formed as a raw material.

The drawing exemplifies the case where cardboard with a smooth surface is used.

That is, a corrugated core 2 made of cardboard has cardboard 3, 3 with a smooth surface attached to both sides, and the total thickness is about 3 to 4.
It is preferable that the pitch (wavelength) of the waves in the center core 2 be approximately 4 to 6 degrees.

Then, hold such a cardboard so that the direction A of one of the crests of the center core 2 is behind the line B connecting the sole of the foot and the toe of the big toe, so that the little finger side, that is, the lateral side , about 1
It is cut to have an inclination angle of 00 to 120 degrees, preferably about 112 degrees.

Furthermore, a wood core 4 is inserted over the entire length of the space C formed by the troughs of each wave and the cardboard on the front and back sides.

This wood core 4 is made of a round bar with a diameter of about 1.8 mm to 2.5 nm or a square bar with a side of about 2 mttt, and its materials include, for example, cottonwood, dorotsuki, willow, kaffir willow, salgurumi, shinatsuki, improved poplar,
Various materials can be used, such as blackberry, aspen, Japanese cedar, peach, and cedar, and in short, any material that is highly hygroscopic may be used.

In addition, on the upper side, a corrugated cardboard with a cardboard 3, which will become the insole base material 1, pasted only on one side of the corrugated core 2 is used to create a space C formed by the corrugations of the core 2 and the cardboard 3 on one side.・
- It may be constructed by inserting a wood core 4 inside.

In this way, the insole 1 uses hygroscopic cardboard and wood, so in the summer there is a risk that moisture from sweat will be absorbed by the cardboard and the wood core and remain permanently attached to the epidermis of the foot. Because it is small, you will not feel any discomfort, and since a moderate amount of voids 5 remain around the wood core 4, this will function as a heat insulating layer in the winter, retaining heat,
In addition to being comfortable to use with less cold sensation, the presence of the wood core 4 on the back side of the smooth cardboard surface leads to the formation of many uneven lines on the surface of the insole as shown in Figure 1 as the insole is used. This not only gives you a gentle feel as if you were walking on Tatami, a so-called crisp feeling, which is even more comfortable, but also provides appropriate stimulation to the soles of your feet every time you run, which can also play a role in improving your health. , this wood core 4... also serves as a reinforcing core to prevent the cardboard from being damaged early due to uneven deformation, thereby improving durability.

In addition, as mentioned above, the wooden core 4... is inclined so that the lateral lateral side is at the back of the throat, which means that the movement of the foot in the shoe when running, that is, when landing, it is on the little toe side, and after landing. When kicking backwards, the inward reciprocating movement is performed along a direction perpendicular to the zo, which improves the grip of the sole of the foot.
As mentioned above, while providing a crisp feel, the insole does not slip between the foot and the insole, providing a comfortable fit that perfectly fits the sole of the foot.

Next, FIG. 3 shows another embodiment, which is formed from an insole base material 1 made of water-permeable non-woven fabric or woven fabric 6 and a wood core 4. A woven fabric or a non-woven fabric 6.6 is attached to each surface using an adhesive or the like.

To attach, use woven or non-woven fabric 6 of this wood core 4.
, 6 may be applied with adhesive 7 to the contact area with the champions to be integrally bonded.

Incidentally, on the upper side, a core made of cardboard may be adhesively interposed between both woven or non-woven fabrics 6, 6, and the wood core 4 may be inserted through the troughs of each wave. Only one piece of cloth or non-woven fabric 6 is used, and a wood core 4 is placed on the back side.
You may also paste...

Furthermore, the corrugated core 2 is attached to the back side of a piece of woven fabric or non-woven fabric 6, and the valleys of this core 2 and the woven fabric or non-woven fabric 6 are bonded.
The wood core 4... may be inserted into the space C... formed by the space C....

In this example, although it is slightly inferior to the previous case using cardboard in terms of hygroscopicity and crispness, it can greatly improve durability.

In addition, the length of the wood cores 4 on each of the above-mentioned sides may be made slightly longer than half of the total length of the space C, and the wood cores 4 may be installed alternately on the left and right, that is, in a staggered manner. It is something.

As detailed in the examples above, the shoe insole according to the present invention consists of a base material made of a water permeable and hygroscopic material made mainly of natural fibers and a wood core. To,
Moisture caused by perspiration is absorbed by the base material core and is prevented from sticking to the epidermis of the foot, causing no discomfort, and a suitable amount of voids remain around the wood core, which acts as a heat insulating layer. Not only does it function as a heat insulator and can be used comfortably in both summer and winter, it does not feel cold, but the presence of the wood core has led to the formation of many parallel uneven lines on the surface of the insole, which makes it easy to use on the soles of your feet. It gives you a gentle feeling as if you are running on Tatami, making it more comfortable to use, and this appropriate stimulation to the soles of your feet stimulates the pressure points on the soles of your feet, thereby improving your health. In addition, this wood core also serves as a reinforcing core to prevent the base material from becoming severely deformed and breaking prematurely, improving the durability of the insole.

Moreover, since it is made of a base material made of natural fibers and a wood core, even if the shoes get wet, they can be dried within a short period of time as long as they are taken out of the shoes and can be used comfortably again. If a set of insoles is used alternately each day, it has the advantage that even though the base material is made of natural fibers, it is always comfortable and can be used for long periods of time.
