2. Description of the Related Art In recent years, the relationship between shoes used in various sports and individual feet of a wearer has an influence on transmission of motor functions such as grip force, and as a result, there is a possibility that a difference in competition performance and fatigue occurs. As they become known, it is imperative among athletes to choose the right shoes for their feet.

For this reason, sports shoes which have been conventionally subjected to heat processing by a special heating device to copy the wearer's last into the insole of the shoe and specially processed so that the insole runs along the sole of the shoe have been used. It improves the degree of adhesion between the sole and the shoe to increase the power of the shoe by increasing the transmission of leg force as well as the stability, comfort and comfort.

[0004]

However, the above-mentioned conventional insoles for sports shoes have to be replaced frequently because they have large settling. In addition, not only a special dedicated heating device for heating and deforming the insole is required, but also a skilled molding worker is required at the time of molding.

[0005] The present invention has been made in view of the above-mentioned problems, and any person can easily imitate the wearer's last with a simple operation without using a dedicated heating device, and at the same time, shaping during use. It is an object of the present invention to provide a shoe insole that can be adjusted, and to propose a molding method of the insole for the simple molding.

[0006]

According to the present invention, a shoe insole conforming to a last is provided with a thin stable cloth on the bottom side of a heat-softening hard resin molded substrate and, if necessary, on a top side. The shock absorbing material is glued or heated to be laminated and integrated, and it has a flat shape similar to the sole shape, and is softened by heating to enable molding to conform to the unevenness of the sole of each shoe wearer. It is an abstract. Further, a heel portion alignment structure in which the outside is heated and bent into a shape substantially along the sole heel portion of the wearer may be formed on the heel portion.

[0007] A method of forming a shoe insole according to a last is a method in which a thin stable fabric is adhered to the bottom surface of a molded substrate of a heat-softening hard resin, and a shock absorbing material is adhered or heated to the upper surface to laminate. Together with the insole, which has a planar shape similar to the sole shape, and an insole molding base made of an elastic block body having an appropriate thickness that is greater in length and width than the insole. After softening the molded substrate by immersing it in hot water, the heat-softened insole is placed on the insole molding base, the sole of the wearer is put on the foot, weight is applied, and the foot is sufficiently deformed. Then, after that, the insole is separated from the insole molding base, immersed in cold water and cooled and solidified, and the surface of the insole is formed into an uneven surface facing the unevenness of the sole of the wearer himself. The gist is that.

[0008]

1 to 3 illustrate a preferred embodiment of a shoe insole according to the present invention, which illustrates a method of forming the insole. Insole 1 according to the present invention
Is replaced with a conventional insole, and is laid on the shoe body 2 for use.

As shown in FIG. 1, an insole 1 is a thin stable cloth 1 on the bottom side of a molded substrate 11 of a heat-softening hard resin made of a relatively thin material such as trans-poly isoprene.
2. A shock absorber 13 made of an elastic sheet material such as foamed polyethylene is adhered or heated on the upper surface side to form a laminated integrated structure, and has a flat shape similar to the outer shape of the sole and can be inserted into the shoe main body 2 or slightly. It has a large shape.

The insole 1 extends from the heel (arrow A) to the inner and outer parts (arrows B and C) as shown in FIG. The heel alignment structure 14 is formed by heating and bending, and the toe side (arrow D) has a flat structure from a substantially central portion.

Reference numeral 3 denotes an insole molding base prepared together with the insole 1, and forms a block body having an appropriate thickness which is made of an elastic material such as foamed polyethylene resin and which is larger in length and width than the insole 1. I do. As will be described later, the insole molding base 3 has an elastic force or a force capable of deforming the heated molded substrate 11 of the insole 1 in a direction orthogonal to the surface of the molded substrate 11 by a drag in a thickness direction due to elasticity. In order to have physical properties such as surface hardness, an apparent density of 20 to 50 kg / m ³ (test method of apparent density measurement: JIS K 6400), durometer hardness E17 to 21 (test method of hardness test: JIS)
K 6253) in the range of 20 to 40 times expanded polyethylene resin.

The method of forming the insole 1 using the insole forming base 3 will be described below with reference to FIG. (1) Remove the insole (pre-laid) from the shoe 2 on which the insole 1 is to be laid, and remove the insole 1 according to the removed insole. Disconnect. At this time, the heel side A of the insole 1 is aligned with the heel alignment structure 1.
It is necessary to leave 4.

(2) Next, the insole 1 is heated with hot water (60 to 80).
(C) for 30 to 50 seconds to soften the molded substrate 11. (3) The heat-softened insole 1 is placed on the insole forming base 3, and the wearer puts his / her weight on one foot so that the heel of the foot is aligned with the depression of the heel alignment structure 14, Continue to step on the arch for a sufficient time to deform (about 30 to 50 seconds).

(4) Thereafter, the insole 1 is separated from the insole forming base 3 and immersed in cold water (about 30 seconds) to be cooled and solidified. The solidified insole 1 is dried after removing moisture, inserted into the shoe body 2 and used in place of the conventional insole.

The insole 1 after the above-mentioned molding is used as the insole molding base 3
Due to the elastic drag of the wearer, irregularities facing the irregularities of the sole of the wearer are formed on the fingertip portion D and the arch portion E, and the curvature previously formed on the heel portion A and the inner and outer portions B and C is also reduced. , Shaped according to the wearer's foot shape.

That is, the insole 1 is provided at the position corresponding to the unevenness of the sole of the wearer's own sole with the fingertip portion D, the arch portion E, the heel portion A, and the inner and outer sides. The portions B and C are formed. Therefore, the insole 1 is processed according to the shape of the sole of the wearer, and the pressure applied to the sole can be reduced from the point pressure to the surface pressure, and the push-up on the sole can be eased. Therefore, stability and support during use of the shoe can be enhanced, and power loss from the sole to the shoe can be prevented.

[0017]

5 to 7 show an embodiment in which the insole 4 is used. Generally, the shock absorbing material 13 is provided on the insole 1 side, but the insole 4 may be inserted under the insole 1 as a structure for enhancing the surface shock absorption and strengthening the shank function and the toe portion. it can.

The insole 4 is integrally attached to the upper surface of the outer sole 21 of the shoe body 2 and includes a toe hard board 41 and a heel hard board 42 made of a hard synthetic resin elastic plate.
On the lower surface side, the middle sole material 43 is laminated, and on the upper surface side, a flat shock-absorbing material (polyethylene resin or the like) 44 having appropriate elasticity in the thickness direction is laminated. .

When the insole 4 is used, the shock absorbing material 13 forming the uppermost layer of the insole 1 can be omitted, and the stability and support during use of the shoe can be further improved, and Since it is possible to prevent power loss from the shoe to the shoe, it is useful to use the spike-shaped shoe for various sports.

[0020]

As described above, according to the shoe insole and the method of forming the insole according to the present invention, the wearer can directly insert the insole into the shoe body. It can be molded to match the irregularities with the soles of the feet, and it can be easily molded by anyone, and the effect obtained by implementing the present invention is extremely large.
