Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe insole applicable to both right and left shoes.

[0002]

2. Description of the Related Art Insole is often used in shoes for the purpose of increasing cushioning properties and for the purpose of preventing moisture and odor.

FIG. 4 is a front view showing a conventional shoe insole.
In the conventional shoe insole, a sheet material or a plate material formed in a shape corresponding to the left and right shoe inner soles is used, and a left foot insole 41 and a right foot insole 42 are provided separately. Have been. Specifically, as shown in FIG.
a, 42a widens toward the base of the finger, the inner foot side is recessed at the arch portions 43, 44, and the heel portions 41b, 4
2b has a slightly wider shape.

[0004] In this manner, since the shape is adapted to the foot shape of the inner bottom of each shoe, the insole fits into the shoe when inserted into the shoe, and can be worn without discomfort.

[0005]

By the way, the above-mentioned conventional insole is sold as a pair of right and left, but if only one insole of the foot is very damaged due to walking habits, etc. However, there is a problem that the excess is wasted. Therefore, it is the current situation that even those who are not very damaged are replaced.

Accordingly, the present invention has been made in view of the above circumstances, and has as its object to provide a shoe insole applicable to both right and left shoes.

[0007]

A two-sided shoe insole according to the present invention is an insole formed of a material which can be bent in all directions, and the width of the central part of the insole is the inside of the shoe. The gist of the present invention is that the bottom portion is formed wider than the center portion in width and symmetrical in the vertical direction.

[0008] A characteristic part representing the difference between the conventional insole for the right foot and the insole for the left foot is that the arch part of the center part of the insole is concave, but in the present invention, a part corresponding to this arch is used. (The center part of the insole) is not dented and wide as described above, and there is no distinction between left and right.

When using the above insole, the shoe is folded into the shape of the shoe bottom in advance and inserted into the shoe, or simply inserted without bending, and then the foot is inserted into the shoe and the inside of the shoe is inserted. The insole may be bent into a shoe inner sole shape by sandwiching the insole, and the insole of the present invention can be used for both right and left shoes.

In the present invention, it is preferable that the toe width of the insole is wider than the toe width of the shoe inner sole.

In some shoes, the width of the thumb portion is wide as the shape of the shoe inner sole. In this case, not only the above-mentioned arch portion but also the right and left characteristics of the shoe inner sole shape of the toes are exhibited. ing. In this regard, the shoe insole of the present invention has a wide toe portion (toe portion) as described above, so that this portion can be appropriately bent to have a shape applicable to both right and left shoes. it can.

Further, in the present invention, the material which can be bent in all directions is obtained by bonding a flat liner material and a step material having a corrugated step to each other, and a top surface of a peak portion in the corrugated step. Is preferably formed using laminated paper that is intermittently depressed when viewed in the direction of the ridgeline of the mountain portion.

[0013] The laminated paper described above is an actual product developed by the present inventor.
3-120462 is similar to the single-sided corrugated cardboard laminated paper disclosed in JP-A No. 3-120462, and in addition to the laminated paper being strong,
Since it can be bent not only vertically and horizontally but also diagonally, it can be bent appropriately to fit the shape of the shoe inner sole.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS <Example 1> FIG. 1 is a front view showing Example 1 of a shoe insole 10 according to the present invention.
The near side in the figure is the surface that contacts the foot.

The insole 10 has outer edges 11a and 11b formed symmetrically with respect to a vertical center line AA (indicated by a two-dot chain line), and a right outer edge 11a of the insole 10 is formed.
(The right side shown in FIG. 1) has a shape conforming to the shape of the outer foot side edge when this insole 10 is used for the right foot, while the left outer edge 11b (the left side shown in FIG. 1) is When the insole 10 is used for the left foot, the shape conforms to the shape of the outer foot side edge. In other words, the left and right outer edges 11a, 1 of the insole 10
1b is formed along one of the inner foot edge and the outer foot edge of the shoe inner sole that is farther than the longitudinal centerline of the shoe inner sole.

Further, in the insole 10, a portion corresponding to the arch for the right foot is marked with a bending line 12 b, and a portion corresponding to the arch for the left foot is also folded. The bend line 12a is marked.

As described above, the insole 10 is wide from the outer edge 11b to the bending line 12b when viewed for the right foot, and is bent from the outer edge 11a when viewed for the left foot. The portion up to 12a is wide. That is, the insole 10
Is widened from the toe portion 10a toward the base of the finger, and reaches the heel portion 10b without being depressed at the arch portion.

FIG. 2 is a partially enlarged perspective view showing an example of the laminated paper constituting the shoe insole 10, and the upper side is a surface in contact with the foot.

The laminated paper 20 is formed by laminating a flat paper liner material 21 and a paper step material 22 with, for example, an adhesive 4. The step member 22 has a stripe-shaped corrugated step in which the peaks 22a and the valleys 22b are alternately continuous, and the depression 22 has a shape in which the top surface of the peak 22a is crushed.
c is formed intermittently in the direction of the ridgeline of the peak 22a.

When the laminated paper 20 is bent in a direction perpendicular to the striped waves (a direction perpendicular to the ridge line), the laminated paper 20 is bent with the depression 22c as a bending point, so that it is easy to bend. When bending in the direction parallel to the striped wave, the bending is easily made since the valley 22b is bent at the bending point. Further, when bending in an oblique direction, the bending can be easily performed by the combination of the valley portion 22b and the depression portion 22c.

When the insole 10 is used for the right foot, the insole 10 is folded along the bending line 12b and inserted into the right foot shoe. Similarly, when the insole 10 is used for the left foot, the insole 10 is folded at the bending line 12a and inserted into the shoe of the left foot. When the length of the insole 10 is long,
It may be used by bending at the end of the heel portion 10b or the toe portion 10a.

As described above, since the insole 10 can be easily bent not only vertically and horizontally but also diagonally, it can be bent along a curve such as the above-mentioned bending lines 12a and 12b. Can fit inside shoes. In addition, even when bending at the heel portion 10b or the toe portion 10a, it can be easily bent.

In the laminated paper, in addition to the double paper, the step material forms a corrugated step, and the depressed portion 22c
Is formed, the strength is high, and it is not easily crushed even when a person's weight is applied.

Furthermore, since the shoe insole 10 is made of paper without using a resin or the like, there is no danger of generating harmful gas at the time of incineration. The impact on the environment is very small.

In addition to the above-mentioned laminated paper, general-purpose general corrugated cardboard may be considered as the durable paper. Since it is made of a material, it is difficult to bend in the direction perpendicular to the stripes, and if it is forcibly bent, the ridge of the step material may be damaged, and it is difficult to bend it into a shoe inner sole shape.

<Embodiment 2> FIG. 3 shows a shoe insole 3 according to the present invention.
0 is a front view showing Example 2 of FIG. 0, and the near side of the figure is a surface in contact with the foot.

In the first embodiment, the ridge line of the striped corrugated step of the laminated paper 20 is formed so as to extend in the vertical direction from the toe to the heel. It is arranged so that the ridge line goes in the direction.

Even if the laminated paper 20 is arranged obliquely in this manner, it is easy to bend at the folding lines 12a, 12b and the like, and by folding in this manner, the insole for the right foot or the left foot can be easily obtained. 30 can be formed.

As described above, the shoe insole according to the present invention has been specifically described with reference to the drawings showing embodiments.
The present invention is not necessarily limited to the above embodiment,
It is also possible to carry out the present invention with appropriate modifications within a range that can be adapted to the gist of the preceding and following descriptions, and these are all included in the technical scope of the present invention.

For example, in the first and second embodiments, the bending line 12
Although only the marks a and 12b are provided, the bent lines 12a and 12b may be pressed to facilitate bending. Further, in order to easily adjust the vertical length of the insole, a pressing line may be provided on the heel portion 10b or the toe portion 10a as a line suitable for various shoe sizes.

Further, the laminated paper is not limited to the U-shaped step as shown in FIG. 2, but may be a V-shaped step or the like, and the V-shaped step shows the same operation and effect as described above. Further, the depression 2
2c may be formed at an equal pitch when viewed in the direction of the ridgeline of the peak 22a, or may be arranged at an irregular pitch. In FIG. 2, the depressions 2 are formed by the adjacent peaks 22a, 22a.
2c is linearly formed at the same position. However, the present invention is not limited to this, and the arrangement position of the depressed portion 22c may be slightly shifted in the ridge direction of the mountain portion 22a. A depression may be formed diagonally with respect to the ridgeline of the mountain 22a.

In addition, decorative paper is laminated on the exposed surface of the liner material or corrugated material of the laminated paper, or is subjected to design printing, or thin paper that does not hinder the foldability of the laminated paper is corrugated. It may be attached to the material side.
