Description

アッパー及びシューズUpper and shoes
　本発明は、アッパー及びこのアッパーを備えるシューズに関する。 The present invention relates to an upper and a shoe including the upper.
　従来のアッパーとして、編物のアッパーが知られている（例えば、特許文献１参照）。編物のアッパーは、布状の基材を含んでいる。 As a conventional upper, a knitted upper is known (for example, see Patent Document 1). The knitted upper includes a fabric-like base material.
　編物のアッパーの基材に色を施す方法として、基材を作製してから基材を染色する後染めが知られている。後染めによって２種類以上の色を基材に施す場合には、異なる材料の糸を２種類以上併用する必要がある。すなわち、異なる材料の糸を編み込んで基材を作製した後に、異なる染料によって異なる材料の糸をそれぞれ染色する必要がある。 One method of applying color to the base material of a knitted upper is piece dyeing, in which the base material is created and then dyed. When applying two or more colors to the base material by piece dyeing, it is necessary to use two or more types of yarn made of different materials in combination. In other words, after yarns made of different materials are knitted to create the base material, each of the yarns made of different materials must be dyed with a different dye.

　異なる材料の糸は、強度、着色性、伸縮性などの物性が同じではないため、従来のように異なる材料の糸を併用することによって２種類以上の色を基材に施すと、物性の劣る糸を使用する必要があるという問題がある。 Threads made of different materials do not have the same physical properties such as strength, colorability, and elasticity, so if you apply two or more colors to the base material by using threads made of different materials together, as in the past, the physical properties will be inferior. There is a problem with the need to use thread.
　本発明は、上記に鑑みてなされたものであって、少なくとも基材の一部の領域において、物性の劣る糸を使用することなく２種類以上の色を施すことが可能となるアッパーを得ることを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to obtain an upper in which it is possible to apply two or more colors to at least a part of the base material without using yarn with poor physical properties. With the goal.
　上述した課題を解決し、目的を達成するために、本発明に係るアッパーは、シューズのアッパーであって、編物である基材を備えている。基材は、アッパーの外部の方を向く表層を含んでいる。表層は、複数本の糸により形成される第１の領域と、複数本の糸により形成されて第１の領域よりも糸の配置密度が高い第２の領域と、を含んでいる。第１の領域の糸と第２の領域の糸とは、同一の材料である。第２の領域には、複数の色が施されている。 In order to solve the above-mentioned problems and achieve the objects, an upper according to the present invention is an upper of a shoe and includes a base material that is a knitted fabric. The base material includes a surface layer facing the exterior of the upper. The surface layer includes a first region formed by a plurality of threads, and a second region formed by a plurality of threads and having a higher thread arrangement density than the first region. The yarn in the first region and the yarn in the second region are the same material. A plurality of colors are applied to the second area.
　本発明に係るアッパーは、少なくとも基材の一部の領域において、物性の劣る糸を使用することなく２種類以上の色を施すことが可能となるという効果を奏する。 The upper according to the present invention has the effect that two or more colors can be applied to at least a part of the base material without using threads with poor physical properties.

　本実施の形態では、図３に示すように、アッパー２は、編物である基材２０を備え、基材２０は、アッパー２の外部の方を向く表層２０ｄを含んでいる。図３から図６に示すように、表層２０ｄは、複数本の糸２０ｇ，２０ｈにより形成される第１の領域２１と、複数本の糸２０ｇ，２０ｈにより形成されて第１の領域２１よりも糸２０ｇ，２０ｈの配置密度が高い第２の領域２２とを含んでいる。第１の領域２１の糸２０ｇ，２０ｈと第２の領域２２の糸２０ｇ，２０ｈとは、同一の材料であり、第２の領域２２には、複数の色が施されている。これらの構成により、同一の材料の糸２０ｇ，２０ｈによって２種類以上の色を第２の領域２２に施すことができるため、少なくとも基材２０の一部の領域において、物性の劣る糸を使用することなく２種類以上の色を施すことが可能となる。また、同一の材料の糸２０ｇ，２０ｈによって第１の領域２１と第２の領域２２とに異なる色を施すことができるため、第１の領域２１と第２の領域２２とにおいて、物性の劣る糸を使用することなく２種類以上の色を施すことが可能となる。すなわち、本実施の形態では、第１の領域２１の色と第２の領域２２の色とを互いに異ならせるとともに２種類以上の色を第２の領域２２に施すことによって、アッパー２の色を３種類以上にした場合でも、物性の劣る糸を使用する必要がない。 In this embodiment, as shown in FIG. 3, the upper 2 includes a base material 20 that is a knitted fabric, and the base material 20 includes a surface layer 20d facing the outside of the upper 2. As shown in FIGS. 3 to 6, the surface layer 20d has a first region 21 formed by a plurality of threads 20g and 20h, and a first region 21 formed by a plurality of threads 20g and 20h. It includes a second region 22 in which the yarns 20g and 20h are arranged at a high density. The threads 20g, 20h in the first region 21 and the threads 20g, 20h in the second region 22 are made of the same material, and the second region 22 is coated with a plurality of colors. With these configurations, two or more colors can be applied to the second region 22 using the threads 20g and 20h made of the same material, so threads with inferior physical properties can be used at least in some regions of the base material 20. It becomes possible to apply two or more types of colors without the need for color. Furthermore, since the first region 21 and the second region 22 can be colored differently using the threads 20g and 20h made of the same material, it is possible to apply different colors to the first region 21 and the second region 22. It becomes possible to apply two or more colors without using thread. That is, in this embodiment, the color of the upper 2 is changed by making the color of the first region 21 and the color of the second region 22 different from each other, and applying two or more kinds of colors to the second region 22. Even if three or more types are used, there is no need to use threads with inferior physical properties.
　本実施の形態では、基材２０が経編で成形された編物である。一般的に、基材が経編で成形された編物である場合には、基材の染色は後染めで行う必要がある。同一の材料の糸によって基材を作製する場合には、後染めでは基材に１色しか施すことができない。一方、後染めによって２種類以上の色を基材に施す場合には、異なる材料の糸を２種類以上併用する必要がある。そうすると、物性の劣る糸を使用する必要がある。この点、本実施の形態では、第１の領域２１の糸２０ｇ，２０ｈと第２の領域２２の糸２０ｇ，２０ｈとが同一の材料であること、第１の領域２１の糸２０ｇ，２０ｈと第２の領域２２の糸２０ｇ，２０ｈとが原料着色されていること、及び、第２の領域２２の糸２０ｈが編み目２０ｉとは独立して自由に配置可能であることにより、基材２０において物性の劣る糸を使用することなく２種類以上の色を施すことが可能となる。なお、基材２０は、緯編で成形された編物でもよい。 In this embodiment, the base material 20 is a knitted fabric formed by warp knitting. Generally, when the base material is a knitted fabric formed by warp knitting, the base material must be dyed by piece dyeing. When the base material is made from threads of the same material, piece dyeing allows only one color to be applied to the base material. On the other hand, when applying two or more colors to a base material by piece dyeing, it is necessary to use two or more types of threads made of different materials. In this case, it is necessary to use yarn with inferior physical properties. In this regard, in this embodiment, the threads 20g, 20h of the first region 21 and the threads 20g, 20h of the second region 22 are made of the same material, and the threads 20g, 20h of the first region 21 are made of the same material. The yarns 20g and 20h in the second region 22 are colored as raw materials, and the yarns 20h in the second region 22 can be freely arranged independently of the stitches 20i, so that the yarns 20g and 20h in the base material 20 It becomes possible to apply two or more colors without using threads with poor physical properties. Note that the base material 20 may be a knitted fabric formed by weft knitting.
　本実施の形態のように第１の領域２１の糸２０ｇ，２０ｈと第２の領域２２の糸２０ｇ，２０ｈとが同一の材料であることにより、基材２０のリサイクルが容易になる。 In this embodiment, the threads 20g, 20h in the first region 21 and the threads 20g, 20h in the second region 22 are made of the same material, which makes it easier to recycle the substrate 20.
　本実施の形態では、図３及び図４に示される第１の領域２１の糸２０ｇ，２０ｈと図５及び図６に示される第２の領域２２の糸２０ｇ，２０ｈとは、スルホン酸基を含まないポリエステル繊維のみで成形されている。この構成により、糸２０ｇ，２０ｈがナイロン繊維、カチオン可染ポリエステル繊維（ＣＤＰ:Cationic　Dyeable　Polyester）などで成形される場合に比べて、基材２０の強度等の物性を高められるとともに基材２０の材料コストの削減を図ることができる。 In this embodiment, the yarns 20g, 20h in the first region 21 shown in FIGS. 3 and 4 and the yarns 20g, 20h in the second region 22 shown in FIGS. 5 and 6 have sulfonic acid groups. Molded only from polyester fibers. With this configuration, the physical properties such as the strength of the base material 20 can be improved, and the physical properties of the base material 20 can be improved, compared to the case where the threads 20g and 20h are made of nylon fiber, cationic dyeable polyester fiber (CDP), etc. Material costs can be reduced.
　糸２０ｇ，２０ｈとして使用するスルホン酸基を含まないポリエステル繊維がリサイクルされたポリエステル繊維である場合には、基材２０の石油由来原料の使用量等を減らして、基材２０の製造コストの削減及び環境負荷の軽減を図ることができる。原料着色された糸２０ｇ，２０ｈであって、かつ、２種類以上の色の糸２０ｇ，２０ｈを使用することにより、基材２０の後染めを行うことなく、２種類以上の色を基材２０に付けられる。また、糸２０ｇ，２０ｈとして使用するスルホン酸基を含まないポリエステル繊維が原料着色されたポリエステル繊維である場合には、基材２０の後染めを行う場合に比べて、基材２０の染色時に使用する電気量及び水量を抑えられるため、基材２０の製造コストの削減及び環境負荷の軽減を図ることができる。 If the polyester fibers that do not contain sulfonic acid groups used as the yarns 20g and 20h are recycled polyester fibers, the amount of petroleum-derived raw materials used in the base material 20 can be reduced, and the manufacturing cost of the base material 20 can be reduced. It is also possible to reduce the environmental burden. By using 20g, 20h of colored yarn as raw materials and 20g, 20h of yarn of two or more colors, two or more colors can be applied to the base material 20 without piece-dying the base material 20. can be attached to In addition, if the polyester fibers that do not contain sulfonic acid groups used as the yarns 20g and 20h are colored polyester fibers, they are used more when dyeing the base material 20 than when piece-dying the base material 20. Since the amount of electricity and water used can be suppressed, it is possible to reduce the manufacturing cost of the base material 20 and reduce the environmental load.
　本実施の形態では、図７及び図８に示すように第１の領域２１は、複数の編み目２０ｉのみが並んで形成される領域であり、図９及び図１０に示すように第２の領域２２は、複数の編み目２０ｉが並んで形成されるとともに編み目２０ｉとは独立して形成された糸２０ｈが配置される領域である。この構成により、着色された糸２０ｈを自由に配置することができるため、基材２０に施す色の配置の自由度を高めることができる。これにより、アッパー２の意匠の表現の幅を広げることができる。すなわち、第２の領域２２の糸２０ｇ，２０ｈが同一の材料である場合でも、２種類以上の色をアッパー２に施すことができる。 In the present embodiment, as shown in FIGS. 7 and 8, the first region 21 is a region in which only a plurality of stitches 20i are formed in line, and as shown in FIGS. 22 is a region where a plurality of stitches 20i are formed side by side and a yarn 20h formed independently of the stitches 20i is arranged. With this configuration, the colored threads 20h can be freely arranged, so that the degree of freedom in arranging the colors applied to the base material 20 can be increased. Thereby, the range of expression of the design of the upper 2 can be expanded. That is, even if the threads 20g and 20h of the second region 22 are made of the same material, the upper 2 can be colored in two or more colors.
　本実施の形態では、図１に示される第２の領域２２の色は、段階的に変化する。この構成により、アッパー２の意匠の表現の幅を広げることができる。 In this embodiment, the color of the second region 22 shown in FIG. 1 changes in stages. This configuration allows for a wider range of expression in the design of the upper 2.
　本実施の形態では、図１に示すように、第１の領域２１には、複数の孔２１ａが形成されている。この構成により、アッパー２の軽量化を図りつつ、アッパー２の伸縮性、通気性等を高めることができる。特に、本実施の形態では、孔２１ａの平面視形状が菱形であることにより、シューズ１の着用者がランニング等の動作を行った際に、足の皮膚の伸び縮みにアッパー２が追従して変形しやすくなる。そのため、アッパー２の足当たりを緩和できるとともに、アッパー２における皺の発生を抑制することができる。 In this embodiment, as shown in FIG. 1, a plurality of holes 21a are formed in the first region 21. With this configuration, while reducing the weight of the upper 2, it is possible to improve elasticity, breathability, etc. of the upper 2. In particular, in this embodiment, since the hole 21a has a rhombic shape in plan view, when the wearer of the shoe 1 performs an action such as running, the upper 2 follows the expansion and contraction of the skin of the foot. It becomes easier to deform. Therefore, it is possible to reduce the impact of the upper 2 on the foot, and to suppress the occurrence of wrinkles in the upper 2.
　本実施の形態では、図３から図６に示すように、基材２０は、アッパー２の外部の方を向く表層２０ｄと、アッパー２の内部の方を向く裏層２０ｅとを含む複数の層を備える。この構成により、複数の層によって、アッパー２の内部に配置される着用者の足を保護することができる。特に、本実施の形態では、基材２０は、表層２０ｄと裏層２０ｅとの間に配置される中間層２０ｆを含む３層であることにより、着用者の足をより一層保護することができる。 In this embodiment, as shown in FIGS. 3 to 6, the base material 20 has a plurality of layers including a surface layer 20d facing the outside of the upper 2 and a back layer 20e facing the inside of the upper 2. Equipped with. With this configuration, the wearer's feet placed inside the upper 2 can be protected by the plurality of layers. In particular, in this embodiment, the base material 20 has three layers including the intermediate layer 20f disposed between the surface layer 20d and the back layer 20e, so that the wearer's feet can be further protected. .
　次に、実施の形態１の変形例について説明する。 Next, a modification of the first embodiment will be described.

The materials for the yarns 20g, 20h in the first region 21 and the yarns 20g, 20h in the second region 22 are, for example, synthetic fibers made from polyester, polyamide, polyurethane, polyolefin, artificial protein, etc., acetate, etc. Semi-synthetic fibers made from raw materials, recycled fibers made from rayon, cupra, etc., natural fibers made from cotton, linen, silk, wool, etc., and inorganic fibers made from glass, metal, carbon, etc. good.
　アッパー２とソール３とは、同一の材料で成形されていてもよい。例えば、アッパー２とソール３とがスルホン酸基を含まないポリエステル繊維で成形されていてもよい。この構成により、シューズ１全体のリサイクルが容易となるため、石油由来原料の使用量等を減らして、シューズ１の製造コストの削減及び環境負荷の軽減を図ることができる。また、例えば、アッパー２とソール３とが熱可塑性ポリエステル系エラストマーで成形されていてもよい。この構成により、反発性の高いソール３を提供することができるため、シューズ１の機能性を向上させることができるとともに、リサイクルが容易なシューズ１を提供することができる。 The upper 2 and sole 3 may be molded from the same material. For example, the upper 2 and sole 3 may be made of polyester fibers that do not contain sulfonic acid groups. With this configuration, the entire shoe 1 can be recycled easily, so the amount of petroleum-derived raw materials used can be reduced, and the manufacturing cost of the shoe 1 can be reduced and the environmental load can be reduced. Further, for example, the upper 2 and sole 3 may be molded from a thermoplastic polyester elastomer. With this configuration, it is possible to provide the sole 3 with high resilience, so that the functionality of the shoe 1 can be improved, and the shoe 1 can be easily recycled.
　アッパー２とソール３とは、類似の材料で成形されていてもよい。本明細書において「類似の材料」とは、共通のモノマー構造を有する高分子材料のことを指す。例えば、アッパー２がスルホン酸基を含まないポリエステル繊維で成形され、ソール３が熱可塑性ポリエステル系エラストマーで成形されていてもよい。この構成により、アッパー２及びソール３のそれぞれの要求特性に適した材料を使用できるとともに、シューズ１が全て類似の材料で成形されるため、シューズ１全体のリサイクルが容易となる。 The upper 2 and sole 3 may be made of similar materials. In this specification, "similar materials" refers to polymeric materials that have a common monomer structure. For example, the upper 2 may be made of polyester fibers that do not contain sulfonic acid groups, and the sole 3 may be made of a thermoplastic polyester elastomer. This configuration allows the use of materials suited to the required characteristics of the upper 2 and sole 3, and because the shoe 1 is made entirely of similar materials, it becomes easy to recycle the entire shoe 1.

　図１５に示すように、第１の領域２１の中間層２０ｆは、糸２０ｇの配置密度が異なる領域を含んでいる。以下、糸２０ｇの配置密度が異なる領域を、密度変化領域２１ｅと称する。図１４には、密度変化領域２１ｅを太い実線で模式的に図示している。密度変化領域２１ｅの平面視形状は、特に制限されないが、本実施の形態では前後方向よりも足幅方向に長い概ね矩形である。密度変化領域２１ｅは、図示した位置に限定されず、適宜変更してもよい。 As shown in FIG. 15, the intermediate layer 20f of the first region 21 includes a region where the arrangement density of the thread 20g is different. Hereinafter, the region where the arrangement density of the thread 20g is different is referred to as the density change region 21e. In FIG. 14, the density change region 21e is shown diagrammatically by a thick solid line. The shape of the density change region 21e in a plan view is not particularly limited, but in this embodiment, it is a roughly rectangular shape that is longer in the foot width direction than in the front-to-back direction. The density change region 21e is not limited to the position shown in the figure, and may be changed as appropriate.
　図１５に示すように、密度変化領域２１ｅの中間層２０ｆにおける糸２０ｇの配置密度は、段階的に変化する。密度変化領域２１ｅの中間層２０ｆにおける糸２０ｇの密度は、本実施の形態では足幅方向の中央から端部に向かうにつれて高くなる。図１５において、紙面左側が足幅方向の中央側であり、紙面右側が足幅方向の端部側である。例えば、密度変化領域２１ｅの足幅方向の中央では糸２０ｇの本数を零にして、隣り合う糸２０ｇの足幅方向の間隔を足幅方向の中央から端部に向かうにつれて狭くすることで、中間層２０ｆにおける糸２０ｇの密度を足幅方向の中央から端部に向かうにつれて高くすることができる。なお、中間層２０ｆにおける糸２０ｇの密度は、足幅方向の端部から中央に向かうにつれて高くなるようにしてもよいし、前後方向の一方から他方に向かうにつれて高くなるようにしてもよい。 As shown in FIG. 15, the arrangement density of the threads 20g in the intermediate layer 20f of the density changing region 21e changes in stages. In this embodiment, the density of the yarn 20g in the intermediate layer 20f of the density change region 21e increases from the center to the end in the foot width direction. In FIG. 15, the left side of the page is the center side in the foot width direction, and the right side of the page is the end side in the foot width direction. For example, the number of threads 20g is zero at the center in the foot width direction of the density change region 21e, and the interval between adjacent threads 20g in the foot width direction is narrowed from the center in the foot width direction toward the ends. The density of the yarn 20g in the layer 20f can be increased from the center to the end in the foot width direction. Note that the density of the yarn 20g in the intermediate layer 20f may increase from the end toward the center in the foot width direction, or may increase from one side to the other in the front-rear direction.
　第１の領域２１の中間層２０ｆは、厚みが異なる領域を含んでいる。以下、中間層２０ｆの厚みが異なる領域を、厚み変化領域２１ｆと称する。図１４には、厚み変化領域２１ｆを太い実線で模式的に図示している。厚み変化領域２１ｆの平面視形状は、特に制限されないが、本実施の形態では前後方向よりも足幅方向に長い概ね矩形である。厚み変化領域２１ｆは、本実施の形態では、密度変化領域２１ｅと一致するが、密度変化領域２１ｅとは別の位置に設けてもよい。すなわち、厚み変化領域２１ｆは、図示した位置に限定されず、適宜変更してもよい。 The intermediate layer 20f of the first region 21 includes regions with different thicknesses. Hereinafter, the region where the thickness of the intermediate layer 20f differs will be referred to as a thickness change region 21f. In FIG. 14, the thickness changing region 21f is schematically illustrated with a thick solid line. The shape of the thickness changing region 21f in plan view is not particularly limited, but in this embodiment, it is generally rectangular, which is longer in the foot width direction than in the front-rear direction. Although the thickness changing region 21f coincides with the density changing region 21e in this embodiment, it may be provided at a different position from the density changing region 21e. That is, the thickness changing region 21f is not limited to the illustrated position, and may be changed as appropriate.
　図１５に示すように、厚み変化領域２１ｆの中間層２０ｆの厚みＤは、段階的に変化する。厚み変化領域２１ｆの中間層２０ｆの厚みＤは、本実施の形態では足幅方向の中央から端部に向かうにつれて高くなる。なお、中間層２０ｆの厚みＤは、足幅方向の端部から中央に向かうにつれて高くなるようにしてもよいし、前後方向の一方から他方に向かうにつれて高くなるようにしてもよい。 As shown in FIG. 15, the thickness D of the intermediate layer 20f in the thickness changing region 21f changes in stages. In this embodiment, the thickness D of the intermediate layer 20f in the thickness changing region 21f increases from the center to the end in the foot width direction. The thickness D of the intermediate layer 20f may increase from the end toward the center in the foot width direction, or may increase from one side to the other in the front-rear direction.
　図１４に示される第１の領域２１のうち斜線ハッチングが付された部分には、孔２１ａが形成されない。図示は省略するが、隣り合う斜線ハッチングが付された部分の間には、孔２１ａが形成される。すなわち、第１の領域２１のうちスロート部２０ｂを挟んだ足幅方向の両側には、孔２１ａが形成される部分と孔２１ａが形成されない部分とが前後方向に交互に配置される。 No hole 21a is formed in the hatched portion of the first region 21 shown in FIG. 14. Although not shown, holes 21a are formed between adjacent hatched portions. That is, on both sides of the first region 21 in the foot width direction across the throat portion 20b, portions where the holes 21a are formed and portions where the holes 21a are not formed are alternately arranged in the front-rear direction.
　次に、本実施の形態に係るアッパー２Ｂ及びシューズ１Ｂの効果について説明する。 Next, the effects of the upper 2B and the shoe 1B according to the present embodiment will be explained.
　アッパー２Ｂでは、中間層２０ｆが有る部分と中間層２０ｆが無い部分とによって材料硬度が異なる。材料硬度が異なると、足の屈曲時等にアッパー２のうち材料硬度が低い箇所に負荷が集中してしまい、アッパー２Ｂの折れ、皺、破壊等が生じやすくなる。本実施の形態では、中間層２０ｆにおける糸２０ｇの配置密度が段階的に変化することにより、足の屈曲時等に発生する負荷を分散させることが可能になる。そのため、アッパー２Ｂの折れ及び皺が目立たなくなり着用者の足に対するフィット感を向上させることができるとともに、アッパー２Ｂの破壊も生じにくくなる。 In the upper 2B, the material hardness differs depending on the portion where the intermediate layer 20f is present and the portion where the intermediate layer 20f is not present. If the materials have different hardnesses, the load will be concentrated on parts of the upper 2 where the material hardness is lower when the foot is bent, and the upper 2B will be more likely to bend, wrinkle, break, etc. In this embodiment, the arrangement density of the threads 20g in the middle layer 20f changes in stages, thereby making it possible to disperse the load that occurs when the foot is bent. Therefore, the folds and wrinkles of the upper 2B become less noticeable, improving the fit to the wearer's feet, and making it difficult for the upper 2B to break.
　本実施の形態では、中間層２０ｆの厚みＤが段階的に変化することにより、前記した段落００６６に記載の効果を奏することができる。また、本実施の形態では、中間層２０ｆの厚みＤが段階的に変化することにより、アッパー２の厚さ方向に高低差のある意匠を表現できるため、立体感による視覚的な効果を創出できる。また、本実施の形態では、中間層２０ｆの厚みＤが段階的に変化することにより、裏層２０ｅが足に部分的に接触するため、シューズ１Ｂの内部の通気性を高めることができる。 In this embodiment, the effect described in paragraph 0066 above can be achieved by changing the thickness D of the intermediate layer 20f in stages. Furthermore, in this embodiment, by changing the thickness D of the intermediate layer 20f in stages, it is possible to express a design with height differences in the thickness direction of the upper 2, thereby creating a visual effect with a three-dimensional effect. . Furthermore, in the present embodiment, since the thickness D of the intermediate layer 20f changes in stages, the back layer 20e comes into partial contact with the foot, thereby increasing the breathability inside the shoe 1B.
（実施の形態４）
　実施の形態４に係るシューズ１Ｃについて図１６を参照して説明する。図１６は、本発明の実施の形態４に係るシューズ１Ｃのアッパー２Ｃを示した展開図である。実施の形態４に係るシューズ１Ｃは、基材２０が第３の領域２５を含む点が、実施の形態１に係るシューズ１と相違する。 (Embodiment 4)
Shoes 1C according to Embodiment 4 will be described with reference to FIG. 16. FIG. 16 is a developed view showing an upper 2C of a shoe 1C according to Embodiment 4 of the present invention. Shoes 1C according to the fourth embodiment differ from the shoes 1 according to the first embodiment in that the base material 20 includes a third region 25.
　図１６に示すように、アッパー２Ｃの基材２０は、複数本の糸２０ｊにより形成される第３の領域２５を含んでいる。図１６では、第３の領域２５に斜線ハッチングを付している。第３の領域２５は、斜線ハッチングの領域のうち第２の領域２２を除く領域である。第３の領域２５は、アッパー中足部Ｒ２の内足側部分に配置されている。第３の領域２５の糸２０ｊの材料は、第１の領域２１の糸２０ｇ，２０ｈの材料及び第２の領域２２の糸２０ｇ，２０ｈの材料とは異なる。例えば、第１の領域２１の糸２０ｇ，２０ｈ及び第２の領域２２の糸２０ｇ，２０ｈがスルホン酸基を含まないポリエステル繊維のみで成形される場合には、第３の領域２５の糸２０ｊはスルホン酸基を含まないポリエステル繊維以外の繊維で成形される。 As shown in FIG. 16, the base material 20 of the upper 2C includes a third region 25 formed by a plurality of threads 20j. In FIG. 16, the third region 25 is hatched. The third region 25 is an area excluding the second area 22 among the diagonally hatched areas. The third region 25 is arranged on the medial foot side portion of the upper midfoot portion R2. The material of the thread 20j in the third region 25 is different from the material of the threads 20g, 20h in the first region 21 and the material of the threads 20g, 20h in the second region 22. For example, when the yarns 20g, 20h in the first region 21 and the yarns 20g, 20h in the second region 22 are formed only from polyester fibers that do not contain sulfonic acid groups, the yarn 20j in the third region 25 is Molded from fibers other than polyester fibers that do not contain sulfonic acid groups.
　次に、本実施の形態に係るアッパー２Ｃ及びシューズ１Ｃの効果について説明する。 Next, the effects of the upper 2C and the shoe 1C according to the present embodiment will be explained.
　アッパー２Ｃを着用者の足にフィットさせるために、アッパー２Ｃの一部には他の部分とは異なる伸縮性が求められる箇所がある。このような箇所として、例えば、アッパー中足部Ｒ２の内足側部分が挙げられる。本実施の形態では、基材２０は、複数本の糸２０ｊにより形成される第３の領域２５を含み、第３の領域２５の糸２０ｊの材料は、第１の領域２１の糸２０ｇ，２０ｈ及び第２の領域２２の糸２０ｇ，２０ｈとは異なる材料である。この構成により、アッパー中足部Ｒ２の内足側部分のように異なる伸縮性が求められる箇所に第３の領域２５を設けることが可能になり、着用者の足へのアッパー２Ｃのフィット性を高めることができる。 In order to fit the upper 2C to the wearer's feet, there are parts of the upper 2C that require different elasticity than other parts. An example of such a location is the medial foot side portion of the upper midfoot portion R2. In this embodiment, the base material 20 includes a third region 25 formed by a plurality of threads 20j, and the material of the threads 20j of the third region 25 is the same as the threads 20g and 20h of the first region 21. The threads 20g and 20h of the second region 22 are made of a different material. This configuration makes it possible to provide the third region 25 at a location where different elasticity is required, such as the medial side portion of the upper midfoot region R2, and improves the fit of the upper 2C to the wearer's foot. can be increased.
　第３の領域２５の糸２０ｊは、第１の領域２１の糸２０ｇ，２０ｈ及び第２の領域２２の糸２０ｇ，２０ｈと類似の材料であってもよい。例えば、第１の領域２１の糸２０ｇ，２０ｈ及び第２の領域２２の糸２０ｇ，２０ｈがスルホン酸基を含まないポリエステル繊維のみで成形され、第３の領域２５の糸２０ｊが熱可塑性ポリエステル系エラストマーで成形されていてもよい。この構成により、アッパー２Ｃの基材２０が全て類似の材料で成形されるため、基材２０のリサイクルが容易になる。 The thread 20j in the third region 25 may be made of a similar material to the threads 20g, 20h in the first region 21 and the threads 20g, 20h in the second region 22. For example, the threads 20g, 20h in the first region 21 and the threads 20g, 20h in the second region 22 may be made of only polyester fibers that do not contain sulfonic acid groups, and the thread 20j in the third region 25 may be made of a thermoplastic polyester elastomer. With this configuration, the base material 20 of the upper 2C is made of similar materials, making it easier to recycle the base material 20.
　以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、実施の形態同士を組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configurations shown in the embodiments above are examples of the content of the present invention, and can be combined with other known techniques, or the embodiments can be combined with each other, It is also possible to omit or change a part of the configuration without departing from the gist of the present invention.
