Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a proper cushioning property, has an effect of evenly contacting the entire sole of the foot during walking, is comfortable to wear, and improves blood circulation of the sole of the foot. The present invention relates to a shoe insole having not only breathability for preventing dampness, but also water absorbency for keeping sweaty sweat by removing sweated sweat from a portion contacting the sole of the foot.

[0002]

2. Description of the Related Art Since the inside of a shoe becomes stuffy due to perspiration during walking or running, as a shoe having a foot stuffing prevention effect, a material with good breathability is used for the armor cover to ventilate with the outside of the shoe. There are sports shoes with improved performance, but since such shoes are the most sweaty and the ventilation of the soles is not considered, the effect of preventing foot stuffiness is sufficiently obtained. Absent.

Conventionally, shoe insoles have often been used for the purpose of improving the wearing comfort, and the thickness and shape of the toes and heels can be changed, and cushioning materials and shock absorbing materials can be used in multiple layers. Although there is a stack of layers, such an insole for shoes cannot be manufactured at low cost due to its complicated structure because it uses a special material.

Therefore, as an insole for shoes having an effect of preventing foot stuffiness, Japanese Patent Application Laid-Open No. 10-295409 discloses an insole in which a double Russell mesh layer and one or more cushion materials are laminated, but this insole is double. Although the breathability and water permeability of the sole side are improved by the Russell mesh layer, the cushioning material in contact with the double Russell mesh layer mitigates the shock applied to the foot while walking and ventilation and soft to the wearer's foot. It is intended to give a feel, and no consideration has been given to absorption of perspiration from the sole of the foot. Further, this cushion material has a disadvantage that it is expensive because it preferably has a very complicated structure of three layers.

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, breathability for preventing foot stuffiness, cushioning for improving wearing comfort, and a portion where soles contact sweated sweat. It is an object of the present invention to provide an insole for shoes, which has a water absorption property that is removed from the product and keeps it in a dry state, and can be manufactured at low cost.

[0006]

As a result of intensive studies to solve the above-mentioned problems, the inventor of the present invention has formed a mesh-like front surface layer and back surface layer with a predetermined interval. If a non-woven fabric having the same thickness as the double Russell cloth and having a predetermined thickness is attached to the back surface layer of the double Russell cloth having the bulkiness, which is bound by the use thread, the double Russell cloth will be formed. Since the space forming thread provides sufficient cushioning properties, it has an effect of evenly contacting the entire sole of the foot during walking, providing comfortable wear and improving blood circulation on the sole of the foot. Not only is it unnecessary to stack multiple layers, but due to its cushioning property, when a part of the double Russell cloth is weighted, that part is compressed and pushes air to the surroundings, and when the load is removed, the air from the surroundings Since it can be inserted, it can generate good air circulation inside the double Russell cloth just by walking, so it has excellent breathability. Furthermore, since a nonwoven fabric is attached to the back side of this double Russell cloth, that nonwoven fabric Has a high water absorbency, the sweat that perspires from the sole of the foot passes through the double Russell cloth and is absorbed, so the side of the double Russell cloth that the foot contacts can be kept in a dry state, and the double Russell The inventors have also completed the present invention by investigating that it can be manufactured at low cost because only the non-woven fabric is attached to the back side of the cloth.

That is, according to the present invention, a double Russell having a bulky property in which a front surface layer and a back surface layer each having a mesh shape are connected by a space forming yarn in a state of maintaining the space at 1.0 to 5.0 mm. A shoe insole is characterized in that a non-woven fabric having a thickness of 1.0 to 5.0 mm and having substantially the same shape as the double Russell cloth is attached to the back surface layer of the cloth.

[0008] In such an insole for shoes, it is preferable that the space forming yarn is a nylon yarn or a tetron yarn having a denier of 50 to 150 because good cushioning property can be obtained and bulkiness can be easily maintained. 25 to 1 layers
It is preferable to use a 50 denier polyester thread because thread breakage is less likely to occur and it is comfortable to wear, and it is preferable to use a synthetic fiber of 3 to 6 denier to obtain appropriate water absorption. as well as/
Or, it is preferable that treatment with a deodorant is performed because deodorant and antibacterial effects are obtained, and if ceramic fiber is kneaded into the fibers constituting the non-woven fabric, it is preferable because the feet are warmed by the far infrared effect. I did.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a shoe insole according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of an embodiment of a shoe insole according to the present invention, FIG. 2 is a right side view of FIG. 1, and FIG. 3 is an enlarged sectional explanatory view of a portion A in FIG.

In the drawings, 1 is a surface layer each having a mesh shape.
A double Russell cloth having bulkiness, in which 1a and the back surface layer 1b are bonded by a space forming thread 1c in a state of keeping the space between 1.0 and 5.0 mm. In this double Russell cloth 1, when the distance between the front surface layer 1a and the rear surface layer 1b is less than 1.0 mm, the air permeability is deteriorated and a sufficient foot stuffiness preventing effect cannot be expected, and the cushioning property is also deteriorated. When walking, the soles of the foot are evenly contacted with each other, which is comfortable to wear and has no effect of improving blood circulation on the sole of the foot.
If it exceeds m, the space forming thread 1c used for maintaining the bulkiness must be extremely thick, so that it is not possible to obtain the effect of evenly abutting the entire sole of the foot during walking. This double Russell cloth 1 has a surface layer
It is preferable that the backing layer 1a and the back surface layer 1b are made of polyester yarn having a denier of 25 to 150 because thread breakage is less likely to occur and comfort is felt, and the yarn 1c for forming the gap is a nylon yarn or a tetron yarn having a denier of 50 to 150 denier. It is preferable because it provides a moderate cushioning property and easily maintains bulkiness.

Reference numeral 2 is a non-woven fabric which has a thickness of 1.0 to 5.0 mm and which has substantially the same shape as the double Russell cloth 1 and which is adhered to the back surface layer 1b of the double Russell cloth 1. It is preferable that 2 is composed of synthetic fibers having a denier of 3 to 6 since a proper water absorption can be obtained, and examples of the synthetic fibers used include nylon, polyester, acryl, polyethylene, polypropylene and the like. If the thickness of the nonwoven fabric 2 is less than 1.0 mm, the water absorption is low and sweat cannot be absorbed sufficiently. If it exceeds 5.0 mm, the absorbed sweat permeates deep into the nonwoven fabric 2 and becomes damp forever. It is not preferable because it will be in a state of

In the shoe insole according to the present invention, the double Russell cloth 1 and the non-woven fabric 2 are provided on the surface opposite to the front surface layer 1a of the back layer 1b of the double Russell cloth 1 so as not to impair the water absorption of the non-woven fabric 2. It can be manufactured by simply sticking with an adhesive applied only to the exposed fibers and then cutting it into a foot shape as shown in FIG.
When kneading in an amount of about 1% by weight, a non-woven fabric 2 formed of fibers preliminarily kneading ceramics may be used. As described above, it is only necessary to perform these treatments before or after cutting into a foot shape, and therefore it is possible to easily and inexpensively manufacture.

Further, the double russell cloth 1 has a drawback that its cut portion is easily frayed, but the shoe insole according to the present invention has a back layer 1b of the double russell cloth 1 as shown in FIGS. Since the space forming thread 1c is also adhered to the nonwoven fabric 2 at the portion bonded to the back surface layer 1b, the space forming thread 1c is resistant to fraying and can withstand long-term use.

[0014]

As described above in detail, the shoe insole according to the present invention is composed of a double Russell cloth and a non-woven cloth, and the double Russell cloth has a mesh-like front surface layer and a back surface layer with a space therebetween. Since it is a cloth having bulkiness that is bonded by a space-forming yarn so as to maintain the distance between 1.0 and 5.0 mm, it has excellent water permeability and breathability, and the space-forming yarn provides sufficient cushioning properties. Since it is obtained, it has the effect of contacting the entire sole of the foot evenly when walking, which is comfortable to wear and improves blood circulation on the sole of the foot, and it is not necessary to stack shock absorbing materials and cushioning materials in multiple layers. Furthermore, due to its cushioning property, when weight is added to a part of the double russell cloth, that part is compressed and pushes air out to the surroundings, and when the load is removed, air flows in from the surroundings, so just by walking, the double russell cloth It has good air circulation inside and has the effect of preventing foot stuffiness. Furthermore, the back layer of the double Russell cloth absorbs perspiration sweat not only in its thickness direction but also in the surface direction. 1.0-5.0 mm
Since a non-woven fabric with a thickness of 3 is attached, it absorbs the sweat that has passed through the double-raschel fabric, so the side of the double-raschel fabric that the sole of the foot contacts can be kept in a dry state, and this nonwoven fabric has a mesh-like back layer. It is easy to dry because it is exposed to the air circulation generated inside the double Russell cloth, so it is possible to obtain an excellent foot stuffy prevention effect, and it is cheap to manufacture because only the double Russell cloth and the non-woven fabric are pasted. You can do it.

When the spacing forming yarn of the double russell cloth is a nylon yarn or a tetron yarn having a denier of 50 to 150, a proper cushioning property can be obtained and the bulkiness can be easily maintained, and the surface layer And the back layer is 25
When it is made of polyester yarn of ˜150 denier, thread breakage is less likely to occur and the wearing comfort can be improved, and when the non-woven fabric is made of synthetic fiber of 3 to 6 denier, appropriate water absorption can be obtained. Further, since the insole according to the present invention has good air permeability as described above, it is possible to structurally suppress the generation of malodor and the growth of bacteria, but the double Russell cloth or the non-woven fabric can be treated with an antibacterial agent and / or a deodorant. If applied, deodorant and antibacterial effects can be obtained,
If ceramic fibers are kneaded into the fibers forming the non-woven fabric, the far infrared effect can warm the feet.

The value of the insole for shoes according to the present invention, which exerts such various effects, is very great.
