Abstract

PURPOSE:To improve the wearing comfortableness of an insole using a single- sided corrugated fiberboard. CONSTITUTION:A single-sided corrugated fiberboard is cut into the shape of an intermediate section 12 existing between a pair of the right and left insoles 10, 10 while parts of connection sections 14, 16 are left respectively. The intermediate section 12 is folded to the shank portion of the insole 10, and the connection sections 14, 16 of the right and left insoles 10, 10 are folded back to surround the intermediate section 12 so that the corrugated portion is faced upward.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole made of single-sided corrugated paper.

[0002]

2. Description of the Related Art The applicant of the present invention has previously proposed a case in which single-sided corrugated paper is used to provide an insole, which is a consumable item, at a low cost, and is durable and comfortable to use. That is,
Corrugated cardboard is reinforced by corrugations, is strong against pressure from above, and has a good feel to the soles of the foot, so it can be used as a suitable material for an insole. In addition, the price is also cheaper than the chemical products used in the past.

In this case, the shoe insole is formed by punching single-sided corrugated paper with a pair of left and right presses using a die having the shape of the shoe insole, leaving a small connecting portion. Then, the connecting portion is cut or folded and used. That is, when cut, the pair of left and right insoles becomes the pair of left and right as it is, and when folded back, it becomes either one of the left and right (using two sets of these sols respectively).

[0004]

Therefore, since the intervening portion existing in the middle of the pair of left and right insoles is unnecessary, it is discarded as it is. On the other hand, in recent footwear such as shoes, it is found that the part of the arch is raised in order to improve the wearing comfort. Focusing on such a point, the present invention folds up the previously discarded interstitial portion on the arch of the foot, folds up the left and right insoles, and wraps it up to raise the arch of the foot. It is a thing.

[0005]

SUMMARY OF THE INVENTION Under the above problems, according to the present invention, a single-sided corrugated board is provided with a pair of left and right shoe insoles, and some connecting portions are provided in the shape of an interstitial portion existing between the shoe insoles. We cut and left it, and folded the interstitial part into the arch of the insole, and provided the insole with the connecting part of the left and right insoles folded back so that the interstitial part was wrapped around the step. It is a thing.

[0006]

[Operation] By taking the above means, that is, by folding the interstitial portion into the arch portion and wrapping it in the left and right insoles, the arch portion can be inflated. Therefore, comfort is improved and fatigue of the feet is reduced.

FIG. 3 is a plan view of a shoe insole according to the present invention. The shoe insole according to the present invention is a pair of left and right insoles 10 made of single-faced corrugated cardboard and an interstitial existing between them. The part 12 and the connecting part 14 and 16 are partially cut on the inner edge side. That is, the interstitial portion 12 and the left and right insoles 10 are connected to each other by the connecting portion 1
They are connected at 6, and then cut at a cutting line 18.
Then, the interstitial portion 12 is folded and overlapped with the arch portion of the insole 10, and the connecting portion 14 of the insole 10 is folded back so that the step 20 is on the surface and wrapped.

FIG. 1 is a bottom view of the insole 10 showing this state, but in order to facilitate this operation, the interstitial portion 12 is shown.
Put the folding lines 22, 24, etc. in advance at the predetermined places of
It folds along this. That is, when the folding line 22 is folded so that it is on the back side, and the folding line 24 is folded so that it is on the inside, the three-layered portion comes to just reach the arch portion. When this is wrapped with the left and right insoles 10, the arch part swells.

FIG. 2 is a plan view showing another example. In this example, the connecting portions 14 and 16 are formed on the outer edge side of the insole 10, and such a method is used. You may. Also in this case, the folding line 2 that serves as a mark for the folding point
It is the same as putting 2, 24, etc. in a predetermined position.
If the interstitial part 12 is wrapped with the left and right insoles 10,
It is more preferable if the insoles 10 are lightly stopped with tape or glue so that the mouth does not open.

FIG. 4 is a plan view of the insole 10 in which the crush line 26 for crushing the step 18 is inserted in the single-sided corrugated paper, and when the crush line 26 is inserted so as to cross the step 20, the step 2 is obtained.
0 is strengthened, and the comfort and durability are also improved. still,
The crush line 26 can be formed by a forming roller or a mold, but the latter has an advantage that it can be processed simultaneously with molding.

On the other hand, the insole 10 is required to have various sizes, but in the present invention, one size can be adjusted by the following two methods. FIG. 5 is a plan view of the insole 10 showing the first method. A plurality of cut lines 28 that can be easily cut by perforations or the like corresponding to each of large and small sizes are provided around the connecting portion 14. It is a method of forming from the toe to the heel. As a result, the consumer can cut off the cutoff line 28 according to the size of his / her foot (or peel it off by hand). This method has the advantage of conforming to the shape of the foot (shoes) for each size.

FIG. 6 is a plan view of the insole 10 showing the second method, but this method uses the cut line 28 only on the heel portion.
Is provided. Since the shape of the insole 10 does not need to completely match the shape of the shoe, this can be sufficiently dealt with. This method has the advantages of low manufacturing cost and easy separation.

[0013]

As described above, according to the present invention, the arch portion of the insole can be inflated by utilizing the intervening portion which has been conventionally discarded, so that the wearing comfort is improved and the foot fatigue is also reduced. Reduce. It also leads to effective use of resources. Further, this method does not increase the cost because only the shape of the press die needs to be changed.
