　例えば、靴のアッパーにおいては、繊維シートに縫い付けた皮革シートによって表面に図形や文字が描かれたりしている。 The upper is required not only to have predetermined characteristics in terms of functions such as strength and breathability, but also to be regarded as important in terms of appearance, and a member such as a leather sheet different from the fiber sheet together with the fiber sheet. May be equipped.
For example, in the upper of shoes, figures and characters are drawn on the surface by a leather sheet sewn on a fiber sheet.
　靴の外観上において特定の図形や文字などを表すために用いられる皮革シートは、通常、一枚の大きな原料シートを刃型で打ち抜く方法によって作製されている。
　前記皮革シートは、原料シートから無駄なく打ち抜くことができる形状になっているとは限らない。
　そのため、原料シートの内、靴の部材として有効利用されずに廃材となってしまう部分の割合は、十分低い状態にはなっていない。
　また、靴におけるこのような目的での皮革シートの利用は、靴の製造工程における手間を増やす要因ともなり得る。
　このため、数多くのデザインの靴を製造しようとすると、製造工程が複雑になったり、多くの廃材が排出されたりする場合がある。 A leather sheet used to represent a specific figure or character on the appearance of a shoe is usually produced by a method of punching a large raw material sheet with a blade.
The leather sheet is not always in a shape that can be punched out from the raw material sheet without waste.
Therefore, the proportion of the raw material sheet that is not effectively used as a shoe member and is wasted is not sufficiently low.
In addition, the use of leather sheets for such purposes in shoes can be a factor that increases the labor in the shoe manufacturing process.
For this reason, when trying to manufacture shoes with many designs, the manufacturing process may be complicated and a large amount of waste material may be discharged.
　本発明は、上記のような問題点に鑑みてなされたもので、種類を増やしても製造工程が複雑になったり、廃材が多く排出されたりするおそれが低い靴を提供することを課題としている。 The present invention has been made in view of the above problems, and an object of the present invention is to provide shoes having a low risk of complicated manufacturing process and a large amount of waste material being discharged even if the number of types is increased. ..
　本発明では、繊維シート自体に図形や文字などを容易に描く方法を提供することで、上記のような課題の解決が図られている。 In the present invention, the above problems are solved by providing a method for easily drawing figures, characters, etc. on the fiber sheet itself.
　上記課題を解決すべく本発明は、
　靴のアッパーであって、
　繊維シートを備え、
　該繊維シートは、靴の外表面を構成する表層、該表層よりも内側に配された内層、及び、前記表層と前記内層との間に設けられた中間層を有し、
　前記表層、前記内層、及び、前記中間層のそれぞれが繊維で構成され、
　該繊維シートには、前記中間層が部分的にしか設けられておらず、該中間層によって前記表層と前記内層とが接続されている接続部と、前記中間層が設けられずに前記表層と前記内層とが接続されていない非接続部とが備えられているアッパーを提供する。 In order to solve the above problems, the present invention

Generally, the upper of a shoe is required to have high breathability in the forefoot portion.
According to the preferred embodiment as described above, such a request can be satisfied.
In particular, in the shoe 1 of the present embodiment, in the forefoot portion 11, the area ratio of the non-connecting portion 21b to the total area of the connecting portion 21a and the non-connecting portion 21b is preferably 25% or more.
The area ratio is more preferably 30% or more, further preferably 35% or more, and particularly preferably 40% or more.
However, if the non-connecting portion 21b is excessively formed, it becomes difficult to exert sufficient strength, so that the area ratio is preferably 95% or less.

　前記非接続部２１ｂは、前記中間層２１２が設けられていないため、表側から見たときに前記表層２１１を通じて前記内層２１３を視認し易い状態になっている。
　従って、本実施形態の前記繊維シート２１は、前記接続部２１ａと前記非接続部２１ｂとが視覚的に異なった状態になり、これらの形状を変更することによって文字や図形などを自由に表現することができる。 The surface layer 211 of the present embodiment is composed of fibers as described above.
The fibers may form the surface layer 211 in the form of threads.
Since the surface layer 211 in the present embodiment is composed of fibers, a gap through which light passes is formed between the fibers and between the threads.
That is, in the upper 2 of the present embodiment, the state of the intermediate layer 212 can be confirmed from the outside through the gap of the surface layer 211.
Since the intermediate layer 212 is not provided in the non-connecting portion 21b, the inner layer 213 is easily visible through the surface layer 211 when viewed from the front side.
Therefore, in the fiber sheet 21 of the present embodiment, the connecting portion 21a and the non-connecting portion 21b are in a visually different state, and characters, figures, and the like can be freely expressed by changing their shapes. be able to.
　前記接続部２１ａでの中間層２１２の様子や、前記非接続部２１ｂでの内層２１３の様子は、表層２１１に形成される前記隙間の大きさが大きいほど確認し易くなる。

　即ち、前記モノフィラメント糸は、顔料やフィラーを含有しないナチュラルカラーの合成樹脂製であることが好ましく、ポリエステルモノフィラメント、ポリアミドモノフィラメント、フロロカーボンモノフィラメントなどであることが好ましい。 The state of the intermediate layer 212 at the connecting portion 21a and the state of the inner layer 213 at the non-connecting portion 21b are easier to confirm as the size of the gap formed in the surface layer 211 is larger.
Therefore, it is preferable that the surface layer 211 is made of threads having a certain thickness.
In the fiber sheet 21 of the present embodiment, the surface layer 211 is composed of the front yarn 2111.
It is preferable that at least a part of the surface layer 211 is made of a monofilament yarn from the viewpoint that the inside state can be easily confirmed.

　前記部材は、繊維シート２１に全く接着されない状態で前記空間部２１０に収容されてもよい。
　その場合、収容する前記部材を前記空間部２１０の内部で移動可能な状態にすべく、該部材を前記非接続部２１ｂの面積に比べて小さなものにしてもよい。
　該部材の大きさ（面積）は、例えば、前記非接続部２１ｂの面積の８０％以下とすることができる。
　前記部材の大きさは、前記非接続部２１ｂの面積の５０％以下であってもよい。
　前記空間部２１０は、複数の部材を収容してもよい。 The member may be housed in the space 210 without being adhered to the fiber sheet 21 at all.
In that case, the member may be made smaller than the area of the non-connecting portion 21b so that the member to be accommodated can be moved inside the space portion 210.
The size (area) of the member can be, for example, 80% or less of the area of the non-connecting portion 21b.
The size of the member may be 50% or less of the area of the non-connecting portion 21b.
The space 210 may accommodate a plurality of members.
　前記繊維シート２１に第１の非接続部２１ｂ（第１の空間部２１０）と第２の非接続部２１ｂ（第２の空間部２１０）とを含む複数の非接続部２１ｂ（空間部２１０）が形成されている場合、第１の空間部２１０に収容する第１の部材と第２の空間部２１０に収容する第２の部材とは、素材や大きさが同じであっても異なっていてもよい。 A plurality of non-connecting portions 21b (space portion 210) including a first non-connecting portion 21b (first space portion 210) and a second non-connecting portion 21b (second space portion 210) in the fiber sheet 21. When is formed, the first member housed in the first space part 210 and the second member housed in the second space part 210 are different even if they have the same material and size. May be good.

　透明なフィルムで構成された中空状のバルーンＰ１を前記空間部２１０に収容させると、前記接続部２１ａと前記非接続部２１ｂとの間に光透過性の違いがより顕著になり得る。 The member accommodated in the space 210 may be, for example, a hollow balloon P1 as shown in FIG.
When the hollow balloon P1 made of a transparent film is housed in the space 210, the difference in light transmission between the connecting portion 21a and the non-connecting portion 21b can become more remarkable.
　前記バルーンＰ１の内部には、気体が収容されても液体が収容されてもよく、粉体が収容されていてもよい。
　前記繊維シート２１は、前記バルーンＰ１が当該繊維シート２１とは異なる色合いとされ、前記接続部２１ａと前記非接続部２１ｂとの見た目の違いがより顕著になっていてもよい。
　この場合、前記バルーンＰ１に色付けしてもよく、該バルーンＰ１を透明にして内部に色のついた液体を収容してもよい。 The inside of the balloon P1 may contain a gas, a liquid, or a powder.
In the fiber sheet 21, the balloon P1 may have a different color from that of the fiber sheet 21, and the difference in appearance between the connecting portion 21a and the non-connecting portion 21b may be more remarkable.
In this case, the balloon P1 may be colored, or the balloon P1 may be made transparent to contain a colored liquid inside.
　前記バルーンＰ１は、例えば、アルミラミネートフィルムのような光反射性に優れた素材で形成されてもよい。
　即ち、前記バルーンＰ１と前記繊維シート２１とのデザイン性の相違は、これらの色合いによって表現されても、光反射性（光沢）の違いによって発現されてもよい。 The balloon P1 may be formed of a material having excellent light reflectivity, such as an aluminum laminated film.
That is, the difference in design between the balloon P1 and the fiber sheet 21 may be expressed by these shades or by the difference in light reflectivity (gloss).
　前記バルーンＰ１が収容されている非接続部２１ｂの表層２１１に前記貫通孔２１１ｈを形成させることで、当該貫通孔２１１ｈを通じて前記繊維シート２１とはデザイン性の異なるバルーンＰ１をアッパー２の外側から直接見ることができるようになる。 By forming the through hole 211h in the surface layer 211 of the non-connecting portion 21b in which the balloon P1 is housed, the balloon P1 having a design different from that of the fiber sheet 21 can be directly inserted from the outside of the upper 2 through the through hole 211h. You will be able to see it.
　前記バルーンＰ１をゴム製にするなどすれば、前記空間部２１０に収容する部材に体積変化を生じさせることができる。

When a member whose volume can be changed is housed in the space 210, for example, as shown in FIG. 7, the balloon P1 is made thicker than the intermediate layer 212, and the non-connecting portion 21b is directed outward. It can also be inflated.
　前記空間部２１０に収容する前記部材としては、例えば、図８に示すように、前記中間層２１２の厚さよりも薄いシートＰ２であってもよい。
　該シートＰ２は、図形や文字などが描かれていてもよい。
　この場合、前記シートＰ２に繊維シート２１とは異なるデザインが施されていると、前記接続部２１ａと前記非接続部２１ｂとの見た目の違いがより明確になる。
　また、内側に前記シートＰ２が収容されている非接続部２１ｂにおいても表層２１１に貫通孔２１１ｈを設けてもよい。 As the member accommodated in the space 210, for example, as shown in FIG. 8, a sheet P2 thinner than the thickness of the intermediate layer 212 may be used.
A figure, a character, or the like may be drawn on the sheet P2.
In this case, if the sheet P2 has a design different from that of the fiber sheet 21, the difference in appearance between the connecting portion 21a and the non-connecting portion 21b becomes clearer.
Further, even in the non-connecting portion 21b in which the sheet P2 is housed inside, a through hole 211h may be provided in the surface layer 211.
　前記空間部２１０は、例えば、図９に示すように、液体を硬化させた硬化物Ｐ３が前記部材として収容されていてもよい。

　前記液体は、金属フレークのような光反射性の粉末を含んでいてもよい。
　前記硬化物が透明である場合、内部における前記粉末の光反射性を前記接続部２１ａと前記非接続部２１ｂとの見た目の違いに有効利用することができる。 The liquid may contain a light-reflecting powder such as metal flakes.
When the cured product is transparent, the light reflectivity of the powder inside can be effectively utilized for the difference in appearance between the connecting portion 21a and the non-connecting portion 21b.
　前記液体は、ウレタンフォームの原液のような発泡性のものであってもよい。
　即ち、前記硬化物Ｐ３は、発泡体であってもよい。
　この場合、前記非接続部２１ｂを前記硬化物Ｐ３（発泡体）によって外側に膨らんだ状態にすることができる。 The liquid may be an effervescent liquid such as a stock solution of urethane foam.
That is, the cured product P3 may be a foam.
In this case, the non-connecting portion 21b can be brought into a state of being bulged outward by the cured product P3 (foam).
　前記硬化物Ｐ３は、バルーンＰ１やシートＰ２と同様に繊維シート２１とは異なるデザインとすることでアッパー２のデザインに利用することができる。
　前記硬化物Ｐ３は、アッパー２の補強にも有効である。
　例えば、後足部１３に前記非接続部２１ｂを設け、該非接続部２１ｂを足の踵を覆うように配置し、該非接続部２１ｂに前記硬化物Ｐ３を設けると、該硬化物Ｐ３がヒールカウンターとしての機能を発揮する。
　この場合、非接続部２１ｂは、踵の内足側、外足側、及び、後方の３方から覆うように設けられることが好ましい。
　前記非接続部２１ｂは、靴底３に接するように設けられることが好ましい。 The cured product P3 can be used for the design of the upper 2 by designing the cured product P3 differently from the fiber sheet 21 like the balloon P1 and the sheet P2.
The cured product P3 is also effective for reinforcing the upper 2.
For example, when the non-connecting portion 21b is provided on the hind foot portion 13, the non-connecting portion 21b is arranged so as to cover the heel of the foot, and the cured product P3 is provided on the non-connecting portion 21b, the cured product P3 becomes a heel counter. Demonstrate the function as.
In this case, the non-connecting portion 21b is preferably provided so as to cover the heel from the inner foot side, the outer foot side, and the rear side.
The non-connecting portion 21b is preferably provided so as to be in contact with the sole 3.
　前記空間部２１０に収容する部材は、上記例示以外のものであってもよい。
　例えば、前記空間部２１０には、糸やコットンのような繊維材を充填してもよい。
　自然状態における前記空間部２１０の容積に対して該繊維材を過充填すれば、前記バルーンＰ１と同様に前記非接続部２１ｂを外向きに膨らませることができる。
　また、前記空間部２１０に収容する前記繊維材は、各種の色合いに着色されていてもよい。 The member accommodated in the space 210 may be other than the above-exemplified members.
For example, the space 210 may be filled with a fiber material such as a thread or cotton.
If the fiber material is overfilled with respect to the volume of the space portion 210 in the natural state, the non-connecting portion 21b can be inflated outward in the same manner as the balloon P1.
Further, the fiber material housed in the space 210 may be colored in various shades.
　本実施形態の繊維シート２１は、このような部材を前記空間部２１０に設けるのに代えて、該空間部２１０に面している前記内層２１３の表面に着色や図形の描画などを施してもよい。 In the fiber sheet 21 of the present embodiment, instead of providing such a member in the space portion 210, the surface of the inner layer 213 facing the space portion 210 may be colored or a figure may be drawn. Good.
　従来のアッパーでは、図形や文字などを描くために、所定の形状に外形加工された皮革シートが繊維シートに取り付けられたりしている。
　本実施形態の靴１では、前記接続部２１ａや前記非接続部２１ｂを特定の形状にすることでアッパー２の形成に用いられる繊維シート自体に文字や図形などが描かれるため皮革シートなどの使用数を従来の靴に比べて減少させることができる。 In the conventional upper, a leather sheet that has been externally processed into a predetermined shape is attached to the fiber sheet in order to draw a figure or a character.
In the shoe 1 of the present embodiment, characters and figures are drawn on the fiber sheet itself used for forming the upper 2 by forming the connecting portion 21a and the non-connecting portion 21b into a specific shape, so that a leather sheet or the like is used. The number can be reduced compared to conventional shoes.
　靴のアッパーの構成部材とされる皮革シートは、通常、この皮革シートよりも面積が大きく皮革シートを数個～数十個採取可能な大きさを有する原料シートから採取される。
　デザインの異なる多くの種類の靴を作製しようとした場合、色や材質の異なる原料シートを用意し、それぞれから所定の形状の皮革シートを採取することになる。
　皮革シートなどを用いなくてもアッパーに様々な図形や文字を表示させることが容易な本実施形態の靴１は、このような従来の靴に比べて製造するのに手間がかからない。
　また、本実施形態の靴１は、製造に際して皮革シートを採取した後の残りの原料シートが廃材となってしまうことが抑制されるため、省資源の観点においても優れている。 The leather sheet, which is a constituent member of the shoe upper, is usually collected from a raw material sheet having a larger area than the leather sheet and a size capable of collecting several to several tens of leather sheets.
When trying to produce many types of shoes with different designs, raw material sheets having different colors and materials are prepared, and leather sheets having a predetermined shape are collected from each sheet.
The shoe 1 of the present embodiment, which makes it easy to display various figures and characters on the upper without using a leather sheet or the like, requires less labor to manufacture than such conventional shoes.
Further, the shoe 1 of the present embodiment is excellent from the viewpoint of resource saving because it is possible to prevent the remaining raw material sheet after collecting the leather sheet from being scrapped during production.
　尚、上記はアッパーや靴に関する本発明の一部の事例を示したものであり、本発明は上記例示に限定されるものではない。
　例えば、上記ではアッパーに備えられた繊維シートが、表層、中間層、及び、内層の３層である場合を例示しているが、本発明のアッパーは、前記内層のさらに内側に別の層を有していてもよい。
　また、このような事項以外についても、本発明は上記例示に各種の変更が加えられ得る。
　即ち、本発明では、その効果が著しく損なわれない範囲において、靴やアッパーに関して従来公知の技術事項を広く採用することができる。 The above is a partial example of the present invention relating to an upper and shoes, and the present invention is not limited to the above examples.
For example, in the above, the case where the fiber sheet provided on the upper has three layers of a surface layer, an intermediate layer, and an inner layer is illustrated, but the upper of the present invention has another layer further inside the inner layer. You may have.
