Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device relates to an insole.

[0002]

[Prior art]

 When wearing shoes, there are problems such as the inside of the shoes getting stuffy and giving off a bad odor, so breathable insoles have been devised. A wide variety of shoe insoles have been proposed, such as using Saran mesh sheets as insoles. Recently, many foamed materials such as urethane are used in the market for the purpose of deodorizing and preventing moisture on the feet, and they have been processed into a concavo-convex shape, and many have been offered to the market.

[0003] In order to stimulate the sole of the foot, a shoe insole having a large number of wart-like irregularities formed on the surface of rubber or the like, or a surface contacting the sole of the foot is formed into a wart-like irregularity. Sandals are considered and are in practical use.

[0004]

[Problems to be solved by the device]

 However, a conventional general insole with a wart-like unevenness formed on the surface of the sheet material that contacts the sole of the foot is generally formed by pouring a raw material such as urethane or rubber into a mold. Since it is manufactured by, the manufacturing process is complicated, and the wart-shaped protrusions are solid, so depending on the material, it may be too hard and the comfort may be impaired.

The present invention has been made in view of the above points, and an object thereof is to provide an insole which is easy to manufacture, has excellent cushioning properties, can be mass-produced, and is inexpensive.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the shoe insole according to the present invention is formed into a foot shape by welding or adhering an air bubble cushioning material having an uneven surface on one side of a base material such as paper, non-woven fabric or woven cloth. is doing.

[0007]

[Action]

 In the insole of the present invention having the above-described structure, the bubble cushioning material is adhered (or welded) onto the flattened base material, and this is adjusted to the size of the foot mold, that is, the inner sole of the shoe. If you insert this insole into your shoes before putting on your shoes, each air bubble in the foam cushioning material will be compressed by the pressure of your foot when you put on your shoes, and the protrusions will have appropriate elasticity. As a result, the back of the foot feels good, and a comfortable stimulus is applied to the back of the leg, and the cushioning property when walking is also excellent. Moreover, since the back surface of the foot is separated from the inner sole of the shoe via the bubble cushioning material, breathability is also obtained. In addition, it is cheap, so you can keep your feet and shoes inside clean at any time, for example by replacing them with a new insole after a few days of use.

Further, the insole of this shoe can be used with the front and back reversed and the bubble cushioning material side facing down. For example, when sweating due to vigorous exercise, the material of the base material should be moisture-proof and deodorant to prevent stuffy feet and bad odors from being absorbed by the base material. Even in this state, the cushioning property can be maintained by the bubble cushioning material on the lower side.

【Example】

 Next, an embodiment of the insole of the present invention will be described with reference to the drawings. FIG. 1 shows a part of a manufacturing process of a shoe insole according to the present invention. In this example, a paper reel 4 around which a continuous cardboard base material 1 is wound, and a trade name "air cap" or " A cushioning material reel 5 around which a nylon barrier air bubble cushioning material 2 called "Capron" is wound, and a winding reel 6 around which a sheet 3 formed by adhering the base material 1 and the bubble cushioning material 2 is wound up. And an adhesive roll 7 for supplying an attachment polymer (adhesive, hereinafter referred to as APP) 14 to the substrate 1 to the paper reel 4, and an upper and lower part between the paper reel 4 and the take-up reel 6. And the adhesive roll 8 arranged in. The attach polymer is an adhesive and is suitable for adhering the bubble cushioning material 2 and the like. The manufacturing apparatus shown in FIG. 1 is simply shown and is merely an example.

The process of manufacturing the sheet 3 will be described with reference to FIG. 1. The AP P14 is supplied to the adhesive roll 7 from above, and the roll 7 rotates in the direction of the arrow so that the APP 14 reaches the surface of the substrate 1, APP14 is uniformly applied to the surface of the material 1. When the base material 1 is paid out in the direction of the take-up reel 6 and passes between the upper and lower bonding rolls 8 on the way, the bubble buffering likewise taken out from the cushioning material reel 5 in the direction of the take-up reel 6 is carried out. It is bonded to the material 2. The upper and lower intervals of the upper and lower bonding rolls 8 are set such that the upper surface of the base material 1 and the lower surface of the bubble cushioning material 2 are brought into close contact with each other while the bubbles of the bubble cushioning material 2 are not crushed. The base material 1 having the bubble cushioning material 2 adhered to the surface thereof is formed into a sheet 3 and wound on the winding reel 6. An example of the dimensions of the sheet 3 is 90 to 120 cm in width and 350 to 400 meters in length.

FIG. 2 is a plan view of the final product obtained by extracting the sheet 3 into the shape of the inner sole of a shoe. The bubbles 9 of the bubble cushioning material 2 are arranged in a concavo-convex pattern on the front surface at regular intervals, and the back surface is made of cardboard. An insole 10 with a substrate 1 is formed. In the insole 10 of the shoe, air bubbles 9 are formed on the entire surface of the insole 10 evenly and in order. 3 is an enlarged cross-sectional view of a part of the insole 10, and FIG. 4 is a further enlarged cross-sectional view of the portion A of FIG. As shown in FIG. 3, the bubble cushioning material 2 is formed by sealing air 11 between polyethylene films 12 and 13 to form bubbles 9, and as shown in FIG. 4, the upper and lower films 12 and 13 are welded at regular intervals. As a result, the bubbles 9 are regularly formed.

Next, a usage mode of the insole 10 configured as described above will be described. The insole 10 is inserted into the shoe with the bubble cushioning material 2 side facing up, and is laid along the inner sole of the shoe. When the foot is put in this state, the foot slides along the surface of the bubble cushioning material 2 and the bubbles of the bubble cushioning material 2 are appropriately compressed. Therefore, a comfortable feel is obtained on the back surface of the foot, and the convex portion formed by the bubbles of the bubble cushioning material 2 appropriately stimulates the sole of the foot to promote blood circulation. Further, since the convex portion of the bubble cushioning material 2 comes into contact with the sole of the foot and does not come into contact with the non-convex portion (that is, the concave portion), a temperature difference can be created. This will also facilitate the decision. In addition, the cushioning properties of the bubble cushioning material 2 are exerted, so that the cushioning material 2 is comfortable to wear and is less likely to get tired even if the user wears shoes for a long time. Moreover, since the bubbles have a heat insulating effect, they are suitable for use in cold regions.

In the above description, an example in which cardboard is used as the base material 1 and a commercially available bubble cushioning material (air cap) 2 is adhered has been described, but the present invention is not limited to cardboard, and depending on the application, Woven cloth, non-woven cloth, Japanese paper, silver processed paper, deodorant and moistureproof processed paper can be used. Further, the air bubble cushioning material to be adhered is not limited to the polyethylene transparent film, but may be an opaque material, and other synthetic resin film or non-woven fabric can also be used by being attached to a thick cardboard.

Even when the insole 10 is used with the bubble cushioning material 2 side facing downward, the cushioning property described above is not impaired, and the paper, cloth, non-woven fabric, etc. of the substrate 1 is subjected to deodorization and moisture proofing. By using the above products, deodorization and moisture prevention are performed, and it is possible to prevent stuffy feet. For example, a processed paper obtained by deodorizing a hygroscopic Japanese paper can be used as the base material 1. Alternatively, the insole 10 may be formed into one large sheet, and the user may cut out the insole 10 according to the size of the foot and use it.

[Effect of device]

 As explained above, the insole of this invention has the following effects.

Conventional insoles are expensive, such as edging a Saran mesh in the shape of a foot or using leather, but are easy to manufacture, suitable for mass production, and can be supplied at extremely low cost. So you can always keep the inside of your shoe clean by discarding it for several days and replacing it. In addition, by reversing the insole, it is possible to prevent odor and moisture, especially in the feet and shoes. In addition, the foot feels good, breathability is expected, blood circulation in the foot is improved, and a heat insulating effect is also exhibited.
