JP2000116407A - Inner sock of shoes - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide inner socks of shoes which are capable of dealing with various kinds of shoe width sizes (E, EE, EEE, etc.), hold the feet in a natural state, provide good air permeability and obviate the fatigue of wearing. SOLUTION: A puff material 1 is formed by packing a polyamide sheet lined with cloth 2 into a metal mold having a curved surface from a toe part of a bottom filler 10 of the shoes to a heel part having a specified height and a rising curved surface along an outside quarter 11 from the bottom filler 10 formed at the peripheral edge from a shank to a heel and molding this sheet by a hot press. A sponge sheet 3 consisting of foamed urethane and a deodorant and antimicrobial sheet 4 are successively laminated atop the puff material 1. At this time, a sponge piece 5 is inserted in a shank portion and a shock absorption mat 6 is inserted between a sponge sheet 3 and the deodorant and antimicrobial sheet 4 in the heel portion.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be applied to various types of shoe insole, especially various shoe width sizes (E, EE, EEE, etc.), the sole of the foot is held in a natural state, and the air permeability is good. For shoes insole that is not tired.

[0002]

2. Description of the Related Art A common shoe insole is made of a high-density polyethylene or polyamide core material that is formed flat according to the inner dimensions of the shoe and covered with a saran net to prevent the feet from becoming stuffy. It is made by attaching a deodorant / antibacterial sheet, or incorporating the deodorizing effect of coconut shell activated carbon.

[0003] In addition, as a slightly improved one, a cushioning material is applied to an arch or a heel portion to improve a fit feeling or absorb a shock during walking, but none of them are satisfactory. Absent.

[0004]

Normally, the heel of men's shoes is 1.5 cm to 2.5 cm in height, so the front of the middle floor of the shoes is generally flat, but from the arch to the heel. Is sloped to the height of the heel, and the recently improved midsole of the shoe has been adapted to fit the curved surface of the arch. Therefore, the flat insole according to the prior art does not fit into the insole of the shoe itself, and furthermore, there is a gap between the insole, the insole of the shoe and the side leather, and is used. Sometimes a sense of incongruity occurs.

[0005] In addition, although various shoe width sizes such as E to EEEE are currently prepared, the insole is not provided with a size corresponding to such shoe width sizes at present. is there.

[0006] There is also a device in which a cushion piece is applied to the arch or heel to improve the fit or absorb a shock during walking. However, since the core material is flat, the fundamental solution is to solve the problem. Can not do.

In view of the problem of the insole according to the prior art, the present invention can correspond to various shoe width sizes (E, EE, EEE, etc.), the foot is held in a natural state, and the air permeability is good. An object of the present invention is to provide a shoe insole which is not worn out.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a method of forming a core material of an insole from a curved surface extending from a toe portion of a middle floor of a shoe to a heel portion having a certain height, and from an arch to a heel. From the middle floor formed on the peripheral edge to the rising curved surface along the side leather, it is molded, and the sponge sheet and the deodorant / antibacterial sheet are sequentially laminated on the upper surface of this core material, the shock absorbing mat on the heel, In the arch part, a fit sponge piece is sandwiched between the sponge sheet and the deodorant / antibacterial sheet, and a plurality of stitch lines are provided on the front edge of the insole in accordance with a shoe width size. Is heated and press-formed from polyamide or high-density polyethylene to fix the shape having the above-mentioned curved surface.

According to the present invention configured as described above, the insole fits well on the midsole of the shoe and the entire area adjacent to the midsole and the side leather, and the entire sole fits well on the insole. It greatly reduces wear fatigue and can be applied to various shoe width sizes.

[0010]

Embodiments of the present invention will be described with reference to the drawings. The core material 1 is made of 0.5
mm polyamide sheet, the curved surface from the toe of the midsole 10 of the shoe to the heel having a certain height, and the rising curved surface along the side leather 11 from the midsole 10 formed on the periphery from the arch to the heel. It is loaded into a mold having the mold and molded by a hot press.

On the upper surface of the core material 1, a sponge sheet 3 made of urethane foam and a deodorant / antibacterial sheet 4 are sequentially laminated. At this time, a fit sponge piece 5 is inserted into the arch and a shock absorbing mat 6 is inserted into the heel between the sponge sheet 3 and the deodorant / antibacterial sheet 4.

As described above, the core material 1, the sponge sheet 3,
A large number of through holes 8 are provided in the insole 7 on which the deodorant / antibacterial sheet 4 is laminated, and a stitch line 9 corresponding to the width of the shoe is provided on the periphery of the front part.

When using the above insole, if the shoe width size is the same, use it as it is, but if the insole is wide, cut off the outside with scissors etc. along the outside of the stitch line. Use according to the shoe width size. There are two stitch lines, for example E size and EE
They are used in different sizes, such as EEE size and EEE size.

[0014]

As described above, the insole according to the present invention is formed in conformity with the curved surface of the midsole of the shoe itself, so that it fits well on the midsole and does not jump in the shoe. It fits well on the sole of the user's foot and is comfortable and comfortable. In addition, it is possible to appropriately cope with a change in the shoe width size, and since the stitch line is provided, the shape of the peripheral edge does not collapse.
