Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole used in a shoe.

[0002]

2. Description of the Related Art Since the size of a foot varies considerably from person to person, shoes also vary in size. The insoles to be laid in the shoes are not available in all sizes, and there are only three types, large, medium and small. The size adjustment within the range of about 2 to 3 cm is instructed to be performed by the person who bought the insole by cutting with a cutter or scissors. Most insoles are enclosed with a cardboard that prints the contours of the insole for each shoe size on cardboard, just like contour lines on a map, and applies the insole to this cut cardboard, The insole is cut and the size is adjusted.

[0003]

However, if an attempt is made to cut with the insole placed on the cut board, the contour printed on the cut board will be hidden by the insole, and the cut will be cut exactly according to the contour. It is difficult.
If you want to cut accurately, you must first cut out the cut backing with contour lines to make a pattern, apply it to the insole, copy the contour of the pattern to the insole with magic or the like, and then cut. In any case, the entire circumference of the edge of the insole had to be cut, which was quite troublesome.

[0004] The functions required of the insole include breathability for suppressing discomfort caused by the inside of the shoe coming off, and cushioning for reducing the impact during walking. The breathability and cushioning properties seemed to neglected one if we squeezed one, and there were few things that were both satisfactory.

[0005] In view of the circumstances described above, the present invention provides an insole that can be easily cut to fit the size of the shoe, has excellent breathability and cushioning properties, and is functionally perfect. The purpose is to do.

[0006]

In order to achieve the above object, the insole according to the first aspect of the present invention provides a guideline, which is a guide when cutting the insole according to the size of the shoe, on the heel side edge. It is characterized in that a plurality is provided at intervals along the space.

According to the present invention, in order to cut the insole according to the size of the shoe, it is not necessary to adjust the width direction of the insole so much, and in many cases, it is sufficient to adjust the length direction only. Was born out of the fact that it is appropriate to cut and adjust the heel side edge. As described above, if multiple guide lines are provided in advance on the heel part of the insole as a guide for cutting, by cutting with scissors along one of the guidelines, the size of the insole is simple and accurate Can be adjusted. The present invention can be applied to insoles made of any material, and any guideline can be used as long as it can be visually confirmed. For example, it may be simply printed on the surface of the insole, or the front and back of the insole may be closely adhered by heat fusion or adhesion,
It may be formed in a streak shape. Even if the heel side of the insole has irregularities due to the guideline, the nerve of the heel is duller than the toe, so there is almost no concern, which is also the reason for providing the guideline on the heel side.

[0008] The insole according to the second aspect of the present invention,
In addition to the configuration of claim 1, the insole is formed of a three-dimensional mesh sheet formed by knitting two mesh fabrics together with a myriad of connecting yarns having a tension and knitting them into a thick sheet. Is characterized in that a non-slip treatment is applied to the mesh ground.

[0009] The three-dimensional mesh sheet is an integral knitted fabric having a three-dimensional stitch structure and a certain thickness. By using this as a material for the insole, it is possible to simultaneously provide the insole with excellent air permeability and cushioning properties. You can have. The three-dimensional mesh sheet can be knitted by a knitting machine having two rows of needle beds such as a double Russell knitting machine, and specific examples thereof include "FUSION-1" (trade name) manufactured by Asahi Kasei Kogyo Co., Ltd. There is. The non-slip treatment is performed by coating the mesh material of this three-dimensional mesh sheet with rubber or synthetic resin, and in order to not impair the air permeability at this time, only around the fibers without closing the voids in the mesh material Coating is preferred.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a plan view and a sectional view of an insole according to the present invention. This insole is configured based on one three-dimensional mesh sheet 1.

As the three-dimensional mesh sheet 1, "FUSION-1" (trade name) manufactured by Asahi Kasei Corporation is used. This is a three-dimensional knitted fabric having a honeycomb structure. The detailed structure is as shown in FIG. 2, and a hexagonal mesh is continuously formed on the upper surface and the lower surface by a yarn 6 in which polyester fibers are knitted in a chain. There is a gap of about 4 mm between the two mesh fabrics 2a and 2b, in which the connecting yarn 3 made of nylon fiber extends innumerably in the vertical direction, and It is woven into the yarn 6 of 2a, 2b. The hexagonal meshes of the two mesh fabrics 2a and 2b are arranged so as to overlap with each other just above and below. There is something to tie. Further, an antibacterial agent and a deodorant are added to each fiber of the mesh fabrics 2a and 2b and the connecting yarn 3. The three-dimensional mesh sheet 1 is not limited to the above-mentioned trade name, and the mesh pattern of the mesh bases 2a and 2b is not limited to a hexagon but may be a rhombus or another shape.

The lower mesh fabric 2b of the three-dimensional mesh sheet 1 is coated with a rubber coating as a non-slip treatment. The process will be described with reference to FIG. 3. The three-dimensional mesh sheet 1 wound in a roll shape is sequentially pulled out and passed through the lower surface side while being immersed in the rubber liquid 8 in the bathtub 7. Rubber liquid 8
Is obtained by blending natural rubber and synthetic rubber with an adhesive such as pine tar. The rubber adheres to the lower surface of the three-dimensional mesh sheet 1 that has exited the bathtub 7 as if it had a single-layer film, but the blower 9 installed just above the three-dimensional mesh sheet 1 blows a strong wind to the mesh fabric 2b. If the rubber attached to the inside of the mesh is blown off and then dried, the adhesive rubber coating 5 can be attached only to the thread 6 of the lower mesh fabric 2b.

The non-slip three-dimensional mesh sheet 1 is cut into an insole shape and sandwiched from above and below by a pair of upper and lower molds heated by a heater. 4 and 4 are formed by heat fusion. Guideline 4 is used as a guide when cutting the insole according to the size of the shoe. A plurality of the insoles are arranged in parallel with each other at intervals of about 5 mm along the heel side edge. There are three (three in FIG. 1). The heat-sealed portion is in a state where the mesh yarns 2a and 2b on the front and back of the three-dimensional mesh sheet 1 and the connecting yarn 3 are melted and joined in a thin plate shape. Even if this portion is cut with scissors, the fibers are cut off. It does not protrude or fall apart.

FIG. 4 shows another embodiment of the insole according to the present invention. This is because guide lines 4, 4, 4, and 4 in the same shape as described above are placed on the surface of an insole integrally formed of an elastic member, for example, urethane resin or cork, at intervals of 5 mm. Is simply printed. Guideline 4,4
Next to 4 and 4, a corresponding shoe size display 11 is written.

[0015]

The insole according to the first aspect of the present invention can be quickly and easily adjusted to a size suitable for the size of the shoe by cutting it with scissors along the guide line formed on the heel side. When the guideline is formed by heat fusion, unevenness due to the guideline is formed on the heel portion of the insole. However, even when the guideline hits the heel, the heel is hardly concerned because the nerve is dull compared to the toe side.

The insole according to the second aspect of the present invention
In addition to the above effects, the use of a three-dimensional mesh sheet that has both air permeability and cushioning properties as a material prevents the inside of the shoes from coming off and absorbs the impact of walking, so it is very functional. It will be excellent. Furthermore, since it has been subjected to a non-slip treatment, it does not slip out of contact with the shoe sole.
