Description

靴shoes
　本発明は、色彩効果を発揮する編地をアッパー材に用いた靴に関する。 The present invention relates to a shoe using a knitted fabric exhibiting a color effect as an upper material.
　靴のアッパー材には、求められる機能や性能に合わせて、織地や編地、合成皮革、樹脂などの種々の素材が用いられており、例えば、通気性や軽量性が求められるランニング用シューズやレーシング用シューズのアッパー材には、一般的に、メッシュ構造のダブルラッセル経編地が用いられている（特許文献１）。 Various materials such as woven fabric, knitted fabric, synthetic leather, and resin are used for the upper material of shoes according to the required function and performance. For example, running shoes and breathable and lightweight are required. In general, a double raschel warp knitted fabric having a mesh structure is used as an upper material of a racing shoe (Patent Document 1).
特開２００４－２３０１５１号公報JP 2004-230151 A
　ところで、近年、靴に対して高いファッション性を求める需要者が増加しており、そのような需要者の要望に応えるべく、靴に優れた美観や躍動感を持たせることが、重要な課題の一つとなっている。しかしながら、上記一般的なダブルラッセル経編地は、それ自体ありふれたデザインであるものが大多数であり、靴に優れた美観等を持たせるという観点からすると、十分であるとは言えない。 By the way, in recent years, the demand for high fashionability for shoes is increasing, and in order to meet the demands of such consumers, it is important to give shoes excellent aesthetics and dynamic feeling. It has become one. However, the above-mentioned general double raschel warp knitted fabrics are mostly common in themselves, and are not sufficient from the viewpoint of giving the shoe an excellent aesthetic appearance.
　また、ランニング用シューズ等に用いられる一般的なダブルラッセル経編地においては、目付や厚みを調整することにより通気性などを変化させることができ、例えば、目付を小さくしたり、厚みを薄くしたりすることで通気性を高めることができる。しかしながら、この場合、目付を小さくすることや厚みを薄くすることに起因した耐久性の低下は避けられないため、従来の一般的なダブルラッセル経編地においては、通気性と耐久性とを両立することが難しいという問題がある。 In general double raschel warp knitted fabrics used for running shoes, etc., the air permeability can be changed by adjusting the basis weight and thickness. For example, the basis weight can be reduced or the thickness can be reduced. To improve air permeability. However, in this case, since a decrease in durability caused by reducing the basis weight or reducing the thickness is inevitable, the conventional general double raschel warp knitted fabric has both air permeability and durability. There is a problem that it is difficult to do.
　更に言えば、一般的なダブルラッセル経編地は、形状復元性が乏しい場合があり、着用回数が増えるにつれて、安定したフィット感が得られ難くなるという問題がある。このように、一般的なダブルラッセル経編地の形状復元性が乏しいのは、引張試験によって得られる応力－ひずみ曲線において、ヒステリシスが生じていることに起因している。 Furthermore, there is a problem that a general double raschel warp knitted fabric may have a poor shape restoration property, and it becomes difficult to obtain a stable fit as the number of wear increases. As described above, the reason that the general double raschel warp knitted fabric has a poor shape restoring property is due to the occurrence of hysteresis in the stress-strain curve obtained by the tensile test.
　本発明は以上の実情に鑑みなされたものであり、優れた美観や躍動感を有するとともに、通気性と耐久性とを兼ね備え、且つ、良好な形状復元性を備えた靴の提供を、その目的とする。 The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a shoe that has excellent aesthetics and dynamic feeling, has breathability and durability, and has good shape restoration properties. And
　上記課題を解決するための本発明は、
　基部と、該基部上に編み立て方向に沿って相互に平行に形成された複数の凸条部とを有し、
　前記凸条部は、編み立て方向に沿って延びた編み列からなる頂部と、編み立て方向に沿って延び、前記基部側が該基部に編み込まれるとともに、前記頂部側が該頂部に係止され、該基部と頂部とを連結するように編成された編み列からなる２つの側壁部とからなり、
　前記頂部及び２つの側壁部のうち、少なくとも１つの部位は、他の部位と異なる色が配置されている編地によって、アッパー材の一部又は全部が形成されている靴に係る。 The present invention for solving the above problems is as follows.
A plurality of ridges formed on the base and parallel to each other along the knitting direction on the base;
The ridge portion includes a top portion formed of a knitting row extending along a knitting direction, and extends along the knitting direction, the base side is knitted to the base portion, and the top side is locked to the top portion, It consists of two side wall parts consisting of a knitting row knitted to connect the base part and the top part,
At least one portion of the top portion and the two side wall portions relates to a shoe in which part or all of the upper material is formed by a knitted fabric in which a color different from that of the other portion is arranged.
　上記靴は、アッパー材の一部又は全部が前記編地によって形成されているため、優れた美観や躍動感を持ったものとなる。 The above shoes have excellent aesthetics and dynamic feeling because part or all of the upper material is formed by the knitted fabric.
　具体的に言うと、前記編地は、凸条部を構成する頂部及び２つの側壁部のうち、少なくとも１つの部位が、他の部位と異なる色が配置されていることによって、観察者が編み立て方向と交差する方向から編地を見る際の位置に応じて、視認される色が変化するという色彩効果を発揮する。 Specifically, the knitted fabric is knitted by an observer because at least one part of the top part and the two side wall parts constituting the ridge part is arranged in a different color from the other parts. The color effect that the color visually recognized changes according to the position at the time of seeing the knitted fabric from the direction crossing the standing direction is exhibited.
　例えば、頂部に配置する色と、２つの側壁部に配置する色とを変えた場合には、編地表面を正面から見ると、頂部に配置した色が視認され、編み立て方向と交差する方向から見ると、頂部に配置した色に加え、側壁部に配置した色が視認される。 For example, when the color arranged on the top part and the color arranged on the two side wall parts are changed, the color arranged on the top part is visually recognized when the surface of the knitted fabric is viewed from the front, and the direction intersecting the knitting direction When viewed from the side, in addition to the color arranged on the top, the color arranged on the side wall is visually recognized.
　また、頂部及び一方の側壁部に配置する色と、他方の側壁部に配置する色とを変えた場合、一方の側壁部側から見ると、頂部及び一方の側壁部に配置した色が視認され、他方の側壁部側から見ると、当該他方の側壁部に配置した色が視認される。 In addition, when the color arranged on the top and one side wall and the color arranged on the other side wall are changed, the color arranged on the top and one side wall is visually recognized when viewed from one side. When viewed from the other side wall, the color arranged on the other side wall is visible.
　また、頂部及び２つの側壁部に配置する色を全て異なる色とした場合、編地表面を正面から見ると、頂部に配置した色が視認され、一方の側壁部側から見ると、頂部に配置した色に加え、当該一方の側壁部に配置した色が視認され、他方の側壁部側から見た場合には、頂部に配置した色及び他方の側壁部に配置した色が視認される。 In addition, when the colors to be arranged on the top part and the two side wall parts are all different colors, when the knitted fabric surface is viewed from the front, the color arranged on the top part is visually recognized, and when viewed from one side wall part side, it is arranged on the top part. In addition to the color, the color arranged on the one side wall is visually recognized, and when viewed from the other side wall, the color arranged on the top and the color arranged on the other side wall are visually recognized.
　このように、前記編地は観察者が当該編地を見る際の位置に応じて視認される色が変化するという色彩効果を発揮するものであるため、当該編地によりアッパー材を形成することで、着用者の足の動きに応じて、編地表面に対する観察者の相対的な位置が変化し、上記色彩効果が発揮され、靴が優れた美観や躍動感を持ったものとなる。 Thus, since the knitted fabric exhibits a color effect that the color visually recognized changes according to the position when the observer views the knitted fabric, the upper material is formed by the knitted fabric. Thus, according to the movement of the wearer's foot, the relative position of the observer with respect to the surface of the knitted fabric is changed, and the above-described color effect is exhibited, and the shoe has an excellent aesthetic appearance and dynamic feeling.
　そして、上記編地は、その側壁部が基部に編み込まれるとともに、頂部に係止されていることにより、編地の凸条部自体の形状安定性が高く、外力が作用してもその形状が変形し難いため、色彩効果の程度が使用態様の影響を受け難く、安定した色彩効果が発揮される。したがって、上記靴は、着用された状態であっても、編地による色彩効果が安定して発揮され、優れた美観や躍動感を持ったものとなる。 The knitted fabric is knitted into the base portion of the knitted fabric and is locked to the top portion, so that the shape stability of the ridge portion of the knitted fabric itself is high, and the shape of the knitted fabric is not affected by external force. Since it is difficult to deform, the degree of the color effect is hardly affected by the usage mode, and a stable color effect is exhibited. Therefore, even when the shoe is worn, the color effect by the knitted fabric is stably exhibited, and the shoe has an excellent aesthetic appearance and dynamic feeling.
　更に、上記靴においては、前記アッパー材を構成する編地が、従来の一般的なダブルラッセル経編地と異なり、その目付等が大きい場合であっても通気性が低下しないため、当該靴は、そのアッパーが耐久性と通気性とを兼ね備えたものとなる。 Further, in the above shoes, since the knitted fabric constituting the upper material is different from the conventional general double raschel warp knitted fabric, even if the basis weight thereof is large, the breathability does not decrease. The upper has both durability and air permeability.
　加えて、前記編地は、従来のダブルラッセル経編地と比較して、応力－ひずみ曲線において、ヒステリシス現象が発生し難いため、当該編地によってアッパー材の一部又は全部が形成された靴は、アッパーが良好な形状復元性を有したものとなり、繰り返し着用した場合であってもフィット感の低下が起き難くなっている。 In addition, since the knitted fabric is less likely to cause a hysteresis phenomenon in the stress-strain curve as compared with the conventional double raschel warp knitted fabric, a shoe in which a part or all of the upper material is formed by the knitted fabric. The upper has a good shape restoring property, and even when it is repeatedly worn, it is difficult for the fit to be lowered.
　尚、上記編地は、前記２つの側壁部にて異なる色が配置されていても良いし、２つの側壁部に配置されている色が１つの編み列中で変化しても良い。更に、２つの側壁部の少なくとも一部が接していても良いし、２つの側壁部の少なくとも一部が繊維によって連結されていても良い。このようにすれば、複雑な模様を表現することが可能となり、多様性に富んだ美観を持たせることができる。 In the knitted fabric, different colors may be arranged on the two side wall portions, and colors arranged on the two side wall portions may change in one knitting row. Furthermore, at least a part of the two side wall parts may be in contact with each other, or at least a part of the two side wall parts may be connected by fibers. In this way, it is possible to express a complicated pattern and to have a diverse and beautiful aesthetic.
　尚、前記編地において、前記頂部は、連結糸によって連結された少なくとも２列の鎖編み列からなり、前記２つの側壁部は、それぞれ鎖編み列からなり、前記側壁部の鎖編み列は、頂部側に形成されたループが前記頂部の鎖編み列中に挿入状態で係止されていることが好ましい。 In the knitted fabric, the top portion is composed of at least two rows of chain knitting rows connected by a connecting yarn, the two side wall portions are each composed of a chain knitting row, and the chain knitting rows of the side wall portions are: It is preferable that the loop formed on the top side is locked in an inserted state in the chain braid row of the top.
　また、前記編地は、前記各凸条部における頂部の一部と、この凸条部に隣接する他の凸条部における頂部の一部との間に前記連結糸が架け渡され、メッシュ部が形成されていても良い。この場合、凸条部同士が相互に隣接する他の凸条部とメッシュ部によって連結された状態となるため、凸条部の形状安定性をより高めることができ、色彩効果がより安定して発揮される。更に、メッシュ部が形成されていることにより、当該メッシュ部の開口部分を通して凸条部が視認されるようになるため、メッシュ部がない場合と比較して、複雑な模様を表現することができ、靴の見た目に多様性を持たせることができる。 In the knitted fabric, the connecting yarn is stretched between a part of the top part of each ridge part and a part of the top part of the other ridge part adjacent to the ridge part, and the mesh part May be formed. In this case, since the ridges are connected to each other by the mesh portion and the other ridges adjacent to each other, the shape stability of the ridges can be further improved, and the color effect is more stable. Demonstrated. Furthermore, since the mesh portion is formed, the ridge portion is visually recognized through the opening portion of the mesh portion, so that a complicated pattern can be expressed as compared with the case without the mesh portion. , The appearance of shoes can be varied.
　更に、前記編地は、前記各凸条部における頂部の一部と、この凸条部に隣接する他の凸条部における頂部の一部との間を連結するように編成された、少なくとも１つの切れ目（開口部）を有する編み領域が形成されていても良い。この場合においても、上記と同様に、編み領域によって凸条部同士が連結された状態となり、当該凸条部の形状安定性が高まり、色彩効果が安定して発揮される。また、切れ目を通して凸条部が視認されるようになるため、編み領域が形成されていない場合に比べ、編地表面に現れる模様を複雑なものにすることができ、靴の外観のバリエーションを増やすことができる。 Furthermore, the knitted fabric is knitted so as to connect between a part of the top part of each ridge part and a part of the top part of another ridge part adjacent to the ridge part. A knitted region having two cuts (openings) may be formed. Also in this case, as described above, the ridges are connected to each other by the knitting region, the shape stability of the ridges is increased, and the color effect is stably exhibited. In addition, since the ridges are visible through the cuts, the pattern appearing on the surface of the knitted fabric can be made more complex than when no knitting area is formed, and the variation in the appearance of shoes is increased. be able to.
　また、前記編地は、前記基部における、前記各凸条部とこの凸条部に隣接する他の凸条部との間に、少なくとも１列の編み列が形成されていても良い。この場合、各凸条部がこれに隣接する凸条部から分離され、各凸条部間の間隔が広くなるため、側壁部を視認することができる観察者の位置の範囲が変化し、各凸条部間の間隔が狭い場合とは異なる色彩効果を発揮させることができる。尚、各凸条部間の間隔を広くし過ぎると、観察者が側壁部を視認することができる位置の範囲が狭くなり過ぎて、色彩効果が十分に発揮されなくなる、或いは、基部の視認される部分が多くなり過ぎて、美観が損なわれる虞がある。したがって、各凸条部の間隔は、１．５ｍｍ～４ｍｍ程度となるようにすることが好ましい。 In the knitted fabric, at least one row of knitting may be formed between each of the ridges and other ridges adjacent to the ridges in the base. In this case, each ridge is separated from the adjacent ridge, and the interval between the ridges is widened, so that the range of the position of the observer who can visually recognize the side wall changes, A color effect different from the case where the space | interval between ridge parts is narrow can be exhibited. If the interval between the ridges is too wide, the range of the position where the observer can visually recognize the side wall portion becomes too narrow, and the color effect is not sufficiently exhibited, or the base portion is visually recognized. There is a risk that the aesthetics will be lost due to excessive parts. Accordingly, it is preferable that the interval between the protruding portions is about 1.5 mm to 4 mm.
　また、前記編地における基部は、メッシュ状に形成しても良い。このようにすることで、編地が軽量化されるとともに通気性も高くなるため、当該編地により形成されたアッパーの軽量化が図られ、且つ通気性も高くなる。 Further, the base in the knitted fabric may be formed in a mesh shape. By doing so, the knitted fabric is reduced in weight and the air permeability is increased, so that the upper formed by the knitted fabric is reduced in weight and the air permeability is also increased.
　また、編糸として透明糸を用いるようにしても良い。このようにすれば、基部を目立たなくして凸条部の色彩を際立たせ、凸条部を構成する頂部及び２つの側壁部に異なる色を配置することによって奏される色彩効果を高めることができる。 Also, transparent yarn may be used as the knitting yarn. In this way, it is possible to enhance the color effect produced by making the base portion inconspicuous and highlighting the color of the ridge, and arranging different colors on the top and the two side walls constituting the ridge. .
　ところで、本願発明者らが鋭意実験を重ねて得た知見によれば、前記編地は、編み立て方向（編み列に沿った方向）における剛性の方が編み列と交差する方向における剛性よりも高い、即ち、編み列に沿った方向には伸縮し難く、編み列と交差する方向には伸縮し易いという特性を有している。 By the way, according to the knowledge obtained by the present inventors through repeated experiments, the knitted fabric is more rigid in the knitting direction (direction along the knitting row) than in the direction intersecting the knitting row. It has a high characteristic, that is, it is difficult to expand and contract in the direction along the knitting row, and easily expands and contracts in the direction intersecting the knitting row.
　そこで、上記靴においては、前記編地の編み列が、靴のソールが載置される基準面と直交する方向に対して＋６０°以内となるように配置されることが好ましい。言い換えれば、上記靴においては、前記編地の編み列が、シューセンター軸を軸周りに周回する方向に対して＋６０°以内となるように配置されることが好ましい。尚、前記基準面と直交する方向に対する角度又はシューセンター軸を軸周りに周回する方向に対する角度は、靴のつま先に向けて倒れる方向を「＋」と定義している。また、「シューセンター軸」とは、足入れした際の第２趾付け根と踵後端とを結ぶ軸を意味する。 Therefore, in the above shoe, it is preferable that the knitting row of the knitted fabric is arranged so as to be within + 60 ° with respect to the direction orthogonal to the reference plane on which the shoe sole is placed. In other words, in the above shoes, it is preferable that the knitting row of the knitted fabric is arranged so as to be within + 60 ° with respect to the direction of the shoe center shaft around the axis. In addition, the angle with respect to the direction orthogonal to the reference plane or the direction with which the shoe center axis circulates around the axis is defined as “+” as the direction of tilting toward the toe of the shoe. The “shoe center axis” means an axis connecting the second heel root and the heel rear end when the foot is inserted.
　このようにすれば、靴の長手方向に沿って編地が伸縮し易くなることで、着用者の足の動きに追随するようにアッパーの一部又は全体が同方向に伸縮自在な状態となり、着用時のフィット感が良好なものとなる。また、靴の長手方向と交差する方向に沿って編地が伸縮し難くなるため、紐締めを行った際に、靴紐（シューレース）に作用した張力による編地の伸びが抑えられ、適切な緊締力で紐締めを行うことができる。 In this way, by making the knitted fabric easily stretchable along the longitudinal direction of the shoe, a part or the whole of the upper becomes stretchable in the same direction so as to follow the movement of the wearer's foot, A good fit when worn. In addition, the knitted fabric is less likely to expand and contract along the direction intersecting with the longitudinal direction of the shoe. Tightening can be performed with a strong tightening force.
　尚、編地の伸びをより抑え、大きな緊締力を得るためには、編地の紐締めを行う際にシューレースに作用する張力の方向と、前記編地の編み列とを平行に近づけることが効果的である。したがって、上記靴においては、前記編地の編み列が、靴のソールが載置される基準面と直交する方向に対して＋３０°から＋６０°の範囲内となるように配置し、前記シューレースに作用する張力の方向と、編み列とが極力平行となるようにすることがより好ましい。 In order to further suppress the stretch of the knitted fabric and obtain a large tightening force, the direction of the tension acting on the shoelace when the lace of the knitted fabric is tightened and the knitting row of the knitted fabric are brought close to each other in parallel. Is effective. Accordingly, in the above shoe, the knitting row of the knitted fabric is arranged so as to be within a range of + 30 ° to + 60 ° with respect to a direction orthogonal to a reference plane on which the shoe sole is placed, and the shoelace More preferably, the direction of the tension acting on the knitting and the knitting row are as parallel as possible.
　また、上記靴においては、アッパーの母趾球部、小趾球部、前足部及び中足部のうちの少なくとも１つの部位が前記編地によって形成されていることが好ましい。このようにすれば、靴を着用した際の足へのフィット性が向上する。 In the above shoes, it is preferable that at least one of the upper baseball part, the small baseball part, the forefoot part and the middle foot part of the upper is formed by the knitted fabric. If it does in this way, the fit nature to a leg at the time of wearing shoes will improve.
　以上のように、本発明に係る靴は、編地が安定した色彩効果を発揮することにより、優れた美観や躍動感を備えたものとなり、また、アッパーが耐久性と通気性とを兼ね備え、且つ、良好な形状復元性を備えたものとなる。 As described above, the shoes according to the present invention have excellent aesthetics and dynamic feeling by exhibiting a stable color effect of the knitted fabric, and the upper has durability and breathability, And it becomes what has favorable shape restoration property.

　前記頂部３は連結糸３ｃによって連結された２本の鎖編み列３ａ，３ｂからなり、側壁部４，５は、後述するループ４ａ１，５ａ１が前記２本の鎖編み列３ａ，３ｂにそれぞれ係止された鎖編み列４ａ，５ａからなる。また、前記基部２は、前記側壁部４，５の鎖編み列４ａ，５ａが結接された鎖編み列２ａ，２ｂと、これら鎖編み列２ａ，２ｂ同士を連結する連結糸２ｃからなり、各凸条部６間に連結された連結部２ｄとから構成されている。尚、図１中において、頂部３を構成する鎖編み列３ａ，３ｂ及び側壁部４，５を構成する鎖編み列４ａ，５ａは実線、頂部３の連結糸３ｃは破線、基部２の連結糸２ｃは点線で示し、基部２の鎖編み列２ａ，２ｂは図示を省略した。 The top portion 3 is composed of two chain knitting rows 3a and 3b connected by a connecting yarn 3c, and the side wall portions 4 and 5 have loops 4a 1 and 5a 1 (to be described later) connected to the two chain knitting rows 3a and 3b. It consists of chain knitting rows 4a and 5a which are locked respectively. The base portion 2 is composed of chain knitting rows 2a and 2b to which the chain knitting rows 4a and 5a of the side wall portions 4 and 5 are connected, and a connecting yarn 2c for connecting the chain knitting rows 2a and 2b to each other. It is comprised from the connection part 2d connected between each protruding item | line part 6. FIG. In FIG. 1, the chain knitting rows 3 a, 3 b constituting the top portion 3 and the chain knitting rows 4 a, 5 a constituting the side wall portions 4, 5 are solid lines, the connecting yarn 3 c at the top portion 3 is a broken line, and the connecting yarn at the base portion 2. 2c is indicated by a dotted line, and the braided rows 2a and 2b of the base 2 are not shown.
　また、この経編地１においては、頂部３を構成する２本の鎖編み列３ａ，３ｂに第１色の編糸、側壁部４を構成する鎖編み列４ａに第２色の編糸、側壁部５の鎖編み列５ａに第３色の編糸をそれぞれ使用し、前記基部２を構成する鎖編み列２ａ，２ｂ及び前記連結糸２ｃ，３ｃには透明な編糸を使用している。尚、前記基部２を構成する鎖編み列２ａ，２ｂは、それぞれ結接される側壁部４，５の鎖編み列４ａ，５ａと同色の色糸を使用しても良く、頂部３の連結糸３ｃは、当該頂部３を構成する鎖編み列３ａ，３ｂと同色の色糸を使用するようにしても良い。 Further, in the warp knitted fabric 1, the two colored knitting yarns 3a and 3b constituting the top portion 3 are knitted in the first color on the two knitting yarn rows 3a and 3b, and the second knitting yarn in the knitting yarn row 4a constituting the side wall portion 4; Third knitting yarns are used for the chain knitting rows 5a of the side wall 5, and transparent knitting yarns are used for the chain knitting rows 2a, 2b and the connecting yarns 2c, 3c constituting the base 2. . In addition, the chain yarns 2a and 2b constituting the base portion 2 may use colored yarns having the same color as the chain yarn rows 4a and 5a of the side wall portions 4 and 5 to be connected to each other. 3c may use color yarns of the same color as the chain knitting rows 3a and 3b constituting the top portion 3.
　尚、この経編地１においては、前記基部２の鎖編み列２ａ，２ｂ、頂部３の鎖編み列３ａ，３ｂ及び連結糸３ｃ、並びに側壁部４，５の鎖編み列４ａ，５ａに用いる編糸として、ポリエステル糸やナイロン糸、レーヨン糸等のフィラメント糸の他、紡績糸などを例示することができる。また、前記基部２の連結糸２ｃとしては、ポリエステルや熱可塑性エラストマー、ナイロンなどからなる透明度の高いモノフィラメント糸を例示することができる。 The warp knitted fabric 1 is used for the chain knitting rows 2a and 2b of the base 2, the chain knitting rows 3a and 3b and the connecting yarn 3c of the top portion 3, and the chain knitting rows 4a and 5a of the side wall portions 4 and 5. Examples of the knitting yarn include polyester yarn, nylon yarn, filament yarn such as rayon yarn, and spun yarn. Moreover, as the connection yarn 2c of the base portion 2, a highly transparent monofilament yarn made of polyester, thermoplastic elastomer, nylon or the like can be exemplified.
　そして、この経編地１は、複数の編針を有し、対向して配置された２列の針床及び当該針床に所定の糸を供給する供給機構を備えた公知のダブルラッセル編み機を用いて編成することができる。 The warp knitted fabric 1 has a plurality of knitting needles, and uses a known double raschel knitting machine having two rows of needle beds arranged opposite to each other and a supply mechanism for supplying a predetermined yarn to the needle beds. Can be organized.
　具体的には、一方側の針床（表側の針床）において、供給機構によって供給される第１色の編糸により２つの鎖編み列３ａ，３ｂを編成しつつ、ウェール方向に隣接するこれら２つの鎖編み列３ａ，３ｂを連結糸３ｃにより連結して頂部３を形成する。 Specifically, in the one side needle bed (front side needle bed), while knitting the two chain knitting rows 3a and 3b with the first color knitting yarn supplied by the supply mechanism, these adjacent to the wale direction Two chain stitch rows 3a and 3b are connected by a connecting yarn 3c to form a top portion 3.
　一方、他方側の針床（裏側の針床）において、供給機構によって供給される第２色及び第３色の編糸により、側壁部４，５を構成する２つの鎖編み列４ａ，５ａをそれぞれ編成するとともに、供給機構によって供給される透明な編糸により、基部２を構成する鎖編み列２ａ，２ｂを編成しつつ、各鎖編み列２ａ，２ｂと、これらの近傍にある他の鎖編み列２ａ，２ｂとをウェール方向に沿って複数の連結糸２ｃにより連結する。 On the other hand, on the other side needle bed (back side needle bed), the two chain knitting rows 4a and 5a constituting the side wall portions 4 and 5 are formed by the second and third color knitting yarns supplied by the supply mechanism. Each knitting row 2a, 2b and other chains in the vicinity thereof are knitted while knitting the chain knitting rows 2a, 2b constituting the base 2 with the transparent knitting yarn supplied by the supply mechanism. The knitting rows 2a and 2b are connected by a plurality of connecting yarns 2c along the wale direction.
　ここで、本例の編地は、側壁部４，５の鎖編み列４ａ，５ａを編成する際に、頂部３の鎖編み列と対向する側（表側の針床と対向する側）にループ４ａ１，５ａ１を形成し、頂部３の鎖編み列３ａ，３ｂの編目に当該ループ４ａ１，５ａ１を挿入するようにして、側壁部４，５の鎖編み列４ａ，５ａを頂部３の鎖編み列３ａ，３ｂに係止する一方、側壁部４，５の鎖編み列４ａ，５ａを、基部２の鎖編み列２ａ，２ｂに編み込むようにして、基部２の鎖編み列２ａ，２ｂと側壁部４，５の鎖編み列４ａ，５ａとをそれぞれ結接するようにしている。 Here, the knitted fabric of this example is looped on the side facing the chain stitch row of the top 3 (side facing the front needle bed) when knitting the chain stitch rows 4a, 5a of the side wall portions 4, 5. 4a 1 and 5a 1 are formed, and the loops 4a 1 and 5a 1 are inserted into the stitches of the chain stitch rows 3a and 3b of the top portion 3 so that the chain stitch rows 4a and 5a of the side wall portions 4 and 5 are inserted into the top portion 3 The chain knitting rows 3a and 3b of the base portion 2 are knitted into the chain knitting rows 2a and 2b of the base portion 2 while the chain knitting rows 4a and 5b of the side wall portions 4 and 5 are knitted into the chain knitting rows 2a and 2b. Are connected to the chain braid rows 4a and 5a of the side wall portions 4 and 5, respectively.
　斯くして、基部２と頂部３とが側壁部４，５によって連結され、頂部３及び側壁部４，５からなる凸条部６が基部２上に形成された一枚の立体的な経編地が編成される。 Thus, the base portion 2 and the top portion 3 are connected by the side wall portions 4 and 5, and the one-dimensional three-dimensional warp knitting in which the protruding portion 6 including the top portion 3 and the side wall portions 4 and 5 is formed on the base portion 2. The ground is organized.
　このように編成された経編地１は、基部２と凸条部６とを編成時に形成するようにしているため、凸条部６の形状にバラツキが生じ難く、各凸条部６の形状がほぼ均一なものとなっている。また、凸条部６は、それぞれ鎖編み列で構成された頂部３と側壁部４，５とからなり、側壁部４，５を構成する鎖編み列４ａ，５ａは、頂部３の鎖編み列３ａ，３ｂに形成されるとともに、基部２の鎖編み列２ａ，２ｂに編み込まれているため、各凸条部６の形状安定性も高いものとなっている。 Since the warp knitted fabric 1 knitted in this way is formed with the base 2 and the ridges 6 at the time of knitting, the shape of the ridges 6 is unlikely to vary, and the shape of each ridge 6 Is almost uniform. Further, the ridge portion 6 includes a top portion 3 and side wall portions 4 and 5 each formed of a chain knitting row, and the chain knitting rows 4a and 5a constituting the side wall portions 4 and 5 are the chain knitting rows of the top portion 3. Since it is formed in 3a, 3b and is knitted in the chain knitting rows 2a, 2b of the base 2, the shape stability of each ridge 6 is high.
　尚、前記基部２から頂部３までの高さｈは、前記ダブルラッセル編み機における対向して配置された２列の針床間の距離や編糸の伸縮度合いに依存するものであるが、高さｈを高くするほど凸条部６の形状は崩れ易くなるため、当該高さｈが１ｍｍ～４ｍｍ程度となるように、針床間の距離を変える、或いは、編成時のテンション等を調整することが好ましい。 The height h from the base 2 to the top 3 depends on the distance between the two needle beds arranged opposite to each other and the degree of expansion / contraction of the knitting yarn in the double raschel knitting machine. As the height h increases, the shape of the ridges 6 tends to collapse. Therefore, the distance between the needle beds is changed or the tension during knitting is adjusted so that the height h is about 1 mm to 4 mm. Is preferred.
　次に、経編地１が奏する色彩効果について、図３を参照しつつ、以下説明する。 Next, the color effect produced by the warp knitted fabric 1 will be described below with reference to FIG.
　この経編地１は、編み立て方向と交差する方向から当該経編地１を見るときの観察者の位置に応じて、視認される色彩が変化する。具体的に言うと、観察者が図３の紙面に向かって左手側の領域Ｒ１内から経編地１を見た場合には、頂部３に加えて側壁部４が視認されるため、観察者は第１及び第２色を視認することができる一方、観察者にとって側壁部５は死角に位置するため、第３色は観察者に視認されない。 The color of the warp knitted fabric 1 changes depending on the position of the observer when viewing the warp knitted fabric 1 from the direction intersecting the knitting direction. Specifically, when the observer views the warp knitted fabric 1 from within the left-hand side region R1 toward the paper surface of FIG. 3, the side wall 4 is visually recognized in addition to the top 3, and thus the observer Can visually recognize the first and second colors, but the third color is not visually recognized by the observer because the side wall portion 5 is positioned at the blind spot for the observer.
　これに対して、観察者が図３の紙面に向かって右手側の領域Ｒ２内から経編地１を見た場合、頂部３に加えて側壁部５が視認されるため、観察者は第１及び第３色を視認することができる一方、側壁部４は観察者から見て死角に位置するため、第２色は観察者に視認されない。尚、本例において、領域Ｒ１及び領域Ｒ２の角度は、およそ４０°～６０°である。 On the other hand, when the observer views the warp knitted fabric 1 from within the right-hand side region R2 toward the paper surface of FIG. While the third color can be visually recognized, the side wall portion 4 is located at a blind spot as viewed from the observer, and therefore the second color is not visually recognized by the observer. In this example, the angles of the region R1 and the region R2 are approximately 40 ° to 60 °.
　図３中の領域Ｒ３及び領域Ｒ４は、それぞれ領域Ｒ１及び領域Ｒ２に付随する領域であり、これら領域Ｒ３及び領域Ｒ４は、例えば、観察者の位置が領域Ｒ１内から領域Ｒ２内へと変わる、即ち、観察者が第１及び第２色を視認している状態から主に第１及び第３色を視認している状態へと移り変わる間を補完して、美妙な色彩効果を奏するのに有効な働きをする領域である。 The region R3 and the region R4 in FIG. 3 are regions associated with the region R1 and the region R2, respectively. For example, the region R3 and the region R4 change the position of the observer from the region R1 to the region R2. That is, it is effective for complementing the transition from the state in which the viewer visually recognizes the first and second colors to the state in which the primary and third colors are mainly viewed, and producing an aesthetic color effect. It is an area where it works.
　このように、経編地１は、観察者が当該経編地１を見る際の位置に応じて、観察者が視認する色が変化する色彩効果を奏するものである。尚、上記経編地１においては、連結糸２ｃに透明な編糸を使用しているため、当該連結糸２ｃに有色糸を用いた場合よりも凸条部６の色彩が際立つようになっている。 As described above, the warp knitted fabric 1 has a color effect in which the color visually recognized by the observer changes according to the position when the observer views the warp knitted fabric 1. In the warp knitted fabric 1, since the transparent knitting yarn is used for the connecting yarn 2c, the color of the ridges 6 becomes more prominent than when the colored yarn is used for the connecting yarn 2c. Yes.
　次に、経編地１の特性について説明する。 Next, the characteristics of the warp knitted fabric 1 will be described.
　図４は、前記経編地１（実施例１）、従来のランニング用シューズに用いられるダブルラッセルメッシュ（比較例１）及びレーシング用シューズに用いられるダブルラッセルメッシュ（比較例２）について、ＪＩＳ　Ｌ１０９６に準拠した引張試験を行い、これにより得られた編み列に沿った方向におけるひずみε１と、編み列と直交する方向におけるひずみε２との比（ε１／ε２）たる初期剛性比を算出した結果を示したグラフである。 FIG. 4 shows JIS L1096 for the warp knitted fabric 1 (Example 1), the double raschel mesh used in conventional running shoes (Comparative Example 1), and the double raschel mesh used in racing shoes (Comparative Example 2). The initial stiffness ratio, which is the ratio of the strain ε 1 in the direction along the knitting row and the strain ε 2 in the direction perpendicular to the knitting row (ε 1 / ε 2 ), is obtained. It is the graph which showed the computed result.
　同図４から分かるように、実施例１は初期剛性比が２以上となっており、編み列に沿った方向（凸条部６に沿った方向）における剛性の方がこれと直交する方向における剛性よりも高く、その差も大きい。このことから、前記経編地１は、凸条部６に沿った方向には伸縮し難く、凸条部６と直交する方向には伸縮し易いという特性を有していることが分かる。これに対して、比較例１は、初期剛性比が０．８程度であり、編み列に沿った方向とこれと直交する方向における剛性の差が小さく、実施例１のような特性を有していない。一方、比較例２は、初期剛性比の値が０．４程度であり、編み列に沿った方向における剛性よりも、これと直交する剛性の方が高く、編み列と直交する方向よりも編み列に沿った方向に伸縮し易くなっており、実施例１のような色彩効果を発揮するものでなく、当該比較例２を靴に使用しても、色彩効果を伴う優れた美観を有するものとはならない。 As can be seen from FIG. 4, in Example 1, the initial stiffness ratio is 2 or more, and the stiffness in the direction along the knitting (direction along the ridges 6) is in the direction orthogonal thereto. It is higher than rigidity and the difference is also great. From this, it can be seen that the warp knitted fabric 1 has the characteristics that it is difficult to expand and contract in the direction along the ridges 6 and easily expands and contracts in the direction perpendicular to the ridges 6. On the other hand, Comparative Example 1 has an initial stiffness ratio of about 0.8, a small difference in stiffness between the direction along the knitting and the direction orthogonal thereto, and has the characteristics as in Example 1. Not. On the other hand, in Comparative Example 2, the value of the initial stiffness ratio is about 0.4, and the rigidity orthogonal to this is higher than the rigidity in the direction along the knitting row, and the knitting is higher than the direction orthogonal to the knitting row. It is easy to expand and contract in the direction along the row, does not exhibit the color effect as in Example 1, and has an excellent aesthetic with color effect even if the comparative example 2 is used for shoes It will not be.
　図５は、実施例１、比較例１について、上記と同様に、ＪＩＳ　Ｌ１０９６に準拠した引張試験を行った結果を示したグラフであり、横軸はひずみε、縦軸は引張荷重（Ｎ）である。尚、この引張試験においては、各試料片に対して編み列に沿った方向に引張荷重をかけた。 FIG. 5 is a graph showing the results of a tensile test based on JIS L1096 in Example 1 and Comparative Example 1 in the same manner as described above, with the horizontal axis representing strain ε and the vertical axis representing tensile load (N). It is. In this tensile test, a tensile load was applied to each sample piece in the direction along the knitting.
　図５から見てとれるように、比較例１においては、ヒステリシス現象が顕著に現れており、大きな残留ひずみが生じているのに対し、実施例１では発生している残留ひずみが極めて小さい。つまり、前記経編地１は、従来のダブルラッセルメッシュと比較し、編み列に沿った方向において、極めて高い形状復元性を有している。 As can be seen from FIG. 5, in Comparative Example 1, the hysteresis phenomenon appears prominently and a large residual strain is generated, whereas in Example 1, the residual strain generated is extremely small. That is, the warp knitted fabric 1 has an extremely high shape restoring property in the direction along the knitting row as compared with the conventional double raschel mesh.
　また、図６は、実施例１、比較例１及び比較例２について、ＪＩＳ　Ｌ１０９６に準拠したフラジール試験法によって空気量を測定した結果をまとめた表であり、表中の目付及び厚みは、試験に用いた各試料片の目付及び厚みを表している。 FIG. 6 is a table summarizing the results of measuring the air amount by the Frazier test method based on JIS L1096 for Example 1, Comparative Example 1 and Comparative Example 2, and the basis weight and thickness in the table are the test results. The basis weight and thickness of each sample piece used in the above are shown.
　同図６から分かるように、実施例１及び比較例２と、比較例１とでは、空気量が大きく異なり、実施例１及び比較例２は良好な通気性を備えている。また、実施例１と比較例２とを比べると、実施例１の方が目付も大きく、且つ厚いにもかかわらず、比較例２と同等の通気性を有している。このことから、前記経編地１は、目付を大きくし、且つ厚みを持たせて適切な耐久性を確保しつつ、十分な通気性も確保できることが分かる。 As can be seen from FIG. 6, Example 1 and Comparative Example 2 and Comparative Example 1 differ greatly in the amount of air, and Example 1 and Comparative Example 2 have good air permeability. Moreover, when Example 1 and Comparative Example 2 are compared, although Example 1 has a larger basis weight and is thicker, it has air permeability equivalent to that of Comparative Example 2. From this, it can be seen that the warp knitted fabric 1 can ensure sufficient air permeability while ensuring appropriate durability while increasing the basis weight and thickness.
　ついで、前記経編地１によってアッパーの一部を形成した靴１０について説明する。 Next, the shoe 10 in which a part of the upper is formed by the warp knitted fabric 1 will be described.
　本例の靴１０は、図７に示すように、着地の衝撃を吸収するソール１１や、足の甲を包むアッパー１２、アッパー１２を足の甲にフィットさせるシューレース１３などを備えている。尚、図７は、靴１０の概略構成を示したものであり、細部については図示を省略している。 As shown in FIG. 7, the shoe 10 of this example includes a sole 11 that absorbs a landing impact, an upper 12 that wraps the instep, and a shoe race 13 that fits the upper 12 to the instep. FIG. 7 shows a schematic configuration of the shoe 10, and details are not shown.
　前記アッパー１２は、図８及び図９に示すように、母趾球部１２ａ、小趾球部１２ｂ、前足部１２ｃ及び中足部１２ｄを含む領域の外皮に前記経編地１が用いられている。尚、図８及び図９においては、経編地１の表面に現れる凸条部６などの形状については図示を省略している。 As shown in FIGS. 8 and 9, the upper 12 has the warp knitted fabric 1 on the outer skin of the region including the main ball portion 12a, the small ball portion 12b, the forefoot portion 12c, and the midfoot portion 12d. Yes. In FIGS. 8 and 9, the shape of the ridges 6 and the like appearing on the surface of the warp knitted fabric 1 is not shown.
　このように、アッパー１２の外皮の一部に前記経編地１を使用することによって、着用者の足の動きに応じて、経編地１の表面に対する観察者の相対的な位置が変化し、経編地１の色彩効果が発揮されるため、靴１０は優れた美観や躍動感を備えたものとなっている。 Thus, by using the warp knitted fabric 1 for a part of the outer skin of the upper 12, the relative position of the observer with respect to the surface of the warp knitted fabric 1 changes according to the movement of the wearer's foot. Since the color effect of the warp knitted fabric 1 is exhibited, the shoe 10 has excellent aesthetics and dynamic feeling.
　また、上述したように、前記経編地１においては、凸条部６の形状のバラツキが非常に少ないため、色彩効果が安定して発揮されるとともに、凸条部６の形状安定性が高いため、着用者の動きによって外力が作用したとしても、色彩効果が安定して発揮される。 In addition, as described above, in the warp knitted fabric 1, since the variation in the shape of the ridge portion 6 is very small, the color effect is stably exhibited and the shape stability of the ridge portion 6 is high. Therefore, even if an external force is applied by the wearer's movement, the color effect is stably exhibited.
　更に、図１０に示すように、前記靴１０においては、経編地１の編み列、言い換えれば、凸条部６が、ソール１１が載置される基準面Ｍと直交する方向（矢印Ｎ）に対して、所定角度θ１（本例においてはおよそ＋３０°）だけ傾斜して配置された状態となるように、当該経編地１を用いるようにし、経編地１が靴１０の長手方向に沿って伸縮し易く、これと交差する方向に沿って伸縮し難い状態となるようにしている。尚、前記靴１０の長手方向に沿って経編地１が伸縮し易い状態にし、且つ、前記長手方向と交差する方向に沿って経編地１が伸縮し難い状態にするためには、前記角度θ１を＋６０°以内にすることが好ましい。 Furthermore, as shown in FIG. 10, in the shoe 10, the knitting row of the warp knitted fabric 1, in other words, the direction in which the ridges 6 are orthogonal to the reference plane M on which the sole 11 is placed (arrow N). The warp knitted fabric 1 is used so that the warp knitted fabric 1 is inclined at a predetermined angle θ 1 (approximately + 30 ° in this example). It is easy to expand and contract along, and it is difficult to expand and contract along the direction intersecting this. In order to make the warp knitted fabric 1 easily stretchable along the longitudinal direction of the shoe 10 and to make the warp knitted fabric 1 difficult to stretch along the direction intersecting the longitudinal direction, The angle θ 1 is preferably within + 60 °.
　このようにすることで、着用者の足の動きに追従するように、前記母趾球部１２ａ、小趾球部１２ｂ、前足部１２ｃ及び中足部１２ｄを含む領域が靴１０の長手方向に沿って伸縮するようになり、着用時のフィット感が良好なものとなる。 By doing in this way, the area | region containing the said main ball part 12a, the small ball part 12b, the forefoot part 12c, and the midfoot part 12d is followed by the longitudinal direction of the shoes 10 so that a motion of a wearer's leg | foot may be followed. Along with the expansion and contraction, the fit when worn is good.
　また、靴１０の長手方向と交差する方向には経編地１が伸縮し難いため、紐締めを行う際に、シューレース１３に作用した張力による経編地１の伸びが抑制される。したがって、適切な緊締力で紐締め行うことができる。 Further, since the warp knitted fabric 1 is difficult to expand and contract in the direction intersecting with the longitudinal direction of the shoe 10, the stretch of the warp knitted fabric 1 due to the tension acting on the shoe race 13 is suppressed when the string is tightened. Therefore, the string can be tightened with an appropriate tightening force.
　尚、紐締め時にシューレース１３に作用する張力の方向と、経編地１の凸条部６に沿った方向とが平行に近づくほど、紐締めを行う際に、経編地１の伸びがより抑えられ、大きな緊締力を得ることができる。したがって、経編地１の凸条部６が、ソール１１が載置される基準面Ｍと直交する方向（矢印Ｎ）に対して、＋３０°から＋６０°だけ傾斜して配置された状態となるように、当該経編地１をアッパー１２に用いるようにすることがより好ましく、例えば、図１１及び図１２に示した靴２０のように、角度θ２がおよそ＋４５°となるように、経編地１をアッパー１２の一部に用いることが好ましい。 In addition, the warp knitted fabric 1 is stretched when the string is tightened so that the direction of the tension acting on the shoe lace 13 and the direction along the ridge portion 6 of the warp knitted fabric 1 become parallel to each other. It is further suppressed and a large tightening force can be obtained. Therefore, the ridge portion 6 of the warp knitted fabric 1 is in a state of being inclined by + 30 ° to + 60 ° with respect to the direction (arrow N) perpendicular to the reference surface M on which the sole 11 is placed. Thus, it is more preferable to use the warp knitted fabric 1 for the upper 12. For example, as in the shoe 20 shown in FIGS. 11 and 12, the warp knitted fabric 1 is warped so that the angle θ 2 is approximately + 45 °. The knitted fabric 1 is preferably used as a part of the upper 12.
　また、上述したように、前記経編地１は、従来のランニング用シューズやレーシング用シューズに用いられるダブルラッセルメッシュと比較して、形状復元性が優れているという特性を有しているため、当該経編地１をアッパー１２の一部として使用することによって、靴１０を繰り返し着用した際のフィット感の低下を抑えることができる。 In addition, as described above, the warp knitted fabric 1 has a characteristic that the shape restoring property is excellent as compared with the double raschel mesh used in conventional running shoes and racing shoes. By using the warp knitted fabric 1 as a part of the upper 12, it is possible to suppress a decrease in fit when the shoe 10 is repeatedly worn.
　更に、本例の靴１０は、通気性と耐久性とを両立可能な経編地１によってアッパー１２の一部が形成されていることにより、当該アッパー１２が通気性と耐久性とを兼ね備えたものとなっている。 Furthermore, in the shoe 10 of this example, a part of the upper 12 is formed by the warp knitted fabric 1 capable of achieving both air permeability and durability, so that the upper 12 has both air permeability and durability. It has become a thing.
　以上、本発明の実施形態について説明したが、本発明が採り得る具体的な態様は何らこれらに限定されるものではない。 As mentioned above, although embodiment of this invention was described, the specific aspect which this invention can take is not limited to these at all.
　例えば、上例の靴１０においては、母趾球部１２ａ、小趾球部１２ｂ、前足部１２ｃ及び中足部１２ｄを含む領域の外皮に前記経編地１を用いるようにしているが、これに限られるものではなく、図１３に示す靴３０のように、後足部を含む領域の外皮に経編地１を用いるようにしても良い。 For example, in the shoe 10 of the above example, the warp knitted fabric 1 is used for the outer skin of the region including the main ball portion 12a, the small ball portion 12b, the forefoot portion 12c, and the midfoot portion 12d. However, the warp knitted fabric 1 may be used for the outer skin of the region including the rear foot portion as in the shoe 30 shown in FIG.
　また、上例の靴１０においては、アッパー１２の外皮に経編地１を用いるようにしているが、これに限られるものでなく、アッパー１２の内皮の一部又は全部を経編地１によって形成しても良い。このようにしても、本発明に係る靴は、経編地１の特性、即ち、凸条部６に沿った方向に伸縮し難く、これと直交する方向に伸縮し易いこと、形状復元性が高いこと、並びに、耐久性及び通気性を兼ね備えることに起因した上記効果を奏するものとなる。 Further, in the shoe 10 of the above example, the warp knitted fabric 1 is used for the outer skin of the upper 12, but the present invention is not limited to this, and part or all of the inner skin of the upper 12 is formed by the warp knitted fabric 1. It may be formed. Even if it does in this way, the shoes concerning this invention are the characteristics of the warp knitted fabric 1, ie, it is hard to expand-contract in the direction along the protruding item | line part 6, and it is easy to expand-contract in the direction orthogonal to this, Shape recovery property The above-mentioned effect resulting from having high and having durability and air permeability is exhibited.

　［第２の経編地］
　図１４及び図１５を参照しつつ、第２の経編地４１について説明する。尚、図１４においては、基部２の鎖編み列２ａ，２ｂの図示を省略し、図１５においては、図１４では図示していない凸条部も図示し、計３つの凸条部を図示するようにした。また、以下の説明において、経編地１と同一の構成については、同一の符号を付し、その詳細な説明は省略する。 [Second warp knitted fabric]
The second warp knitted fabric 41 will be described with reference to FIGS. 14 and 15. In FIG. 14, the illustration of the braided rows 2 a and 2 b of the base 2 is omitted, and in FIG. 15, the ridges not shown in FIG. 14 are also shown, and a total of three ridges are shown. I did it. Moreover, in the following description, about the structure same as the warp knitted fabric 1, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.
　図１４及び図１５に示すように、当該第２の経編地４１は、前記基部２の連結部２ｄに当該基部２を構成する鎖編み列２ｅが連結糸２ｃとは別の編糸によって編成され、当該鎖編み列２ｅを含む鎖編み列２ａ，２ｂ，２ｅと、これらの近傍に位置する他の鎖編み列２ａ，２ｂ，２ｅとがウェール方向において複数の連結糸２ｃにより連結され編成されている。尚、前記鎖編み列２ｅに用いられる編糸は有色無色を問わないが、透明な編糸を用いることによって、凸条部６の色彩を容易に際立たせることができる。 As shown in FIGS. 14 and 15, the second warp knitted fabric 41 is knitted with a knitting yarn different from the connecting yarn 2 c such that the chain knitting row 2 e constituting the base 2 is connected to the connecting portion 2 d of the base 2. The chain knitting rows 2a, 2b, 2e including the chain knitting row 2e and the other chain knitting rows 2a, 2b, 2e located in the vicinity thereof are connected and knitted by a plurality of connecting yarns 2c in the wale direction. ing. The knitting yarn used in the chain knitting row 2e may be colored or colorless, but the color of the ridges 6 can be easily highlighted by using a transparent knitting yarn.
　この経編地４１においては、基部２の連結部２ｄに鎖編み列２ｅが更に編成されていることにより、経編地１と比較して各凸条部６間の間隔が広がっている。そのため、図１６に示すように、頂部３及び側壁部４が視認される領域Ｒ１’並びに頂部３及び側壁部５が視認される領域Ｒ２’は、経編地１における領域Ｒ１及び領域Ｒ２よりも狭くなる一方、領域Ｒ３’及び領域Ｒ４’は、領域Ｒ３及び領域Ｒ４よりも広くなっている。 In the warp knitted fabric 41, the chain knitting row 2 e is further knitted on the connecting portion 2 d of the base 2, so that the interval between the ridges 6 is wider than that of the warp knitted fabric 1. Therefore, as shown in FIG. 16, the region R1 ′ where the top portion 3 and the side wall portion 4 are visually recognized and the region R2 ′ where the top portion 3 and the side wall portion 5 are visible are more than the region R1 and the region R2 in the warp knitted fabric 1. On the other hand, the region R3 ′ and the region R4 ′ are wider than the region R3 and the region R4.
　このように、当該経編地４１は、領域Ｒ３’及び領域Ｒ４’が広がっていることにより、より一層鮮明な色彩変化を発揮する。 Thus, the warp knitted fabric 41 exhibits a more vivid color change due to the expansion of the region R3 'and the region R4'.
　尚、連結部２ｄに編成する鎖編み列２ｅの数は、必ずしも１列に限られず、２列以上であっても良いが、凸条部６間の間隔が空きすぎると、領域Ｒ１’及び領域Ｒ２’が狭くなり過ぎて色彩効果が十分に発揮されなくなる、或いは、基部２の露出が多くなり過ぎて美感が損なわれる虞がある。したがって、凸条部６の高さｈも考慮して、領域Ｒ１’及び領域Ｒ２’の範囲が適切な値（好ましくはおよそ２０°以上）となり、領域Ｒ３’及び領域Ｒ４’の範囲が適切な値（好ましくは４０°以上）となり、各凸条部６間の間隔ｌが１．５ｍｍ～４ｍｍ程度（編針３本～５本分程度）となるように、鎖編み列２ｅの数を決めることが好ましい。 Note that the number of the chain knitting rows 2e knitted to the connecting portion 2d is not necessarily limited to one row, and may be two or more rows. However, if the interval between the ridge portions 6 is too large, the region R1 ′ and the region There is a possibility that R2 'becomes too narrow and the color effect is not sufficiently exhibited, or the exposure of the base portion 2 becomes too much and the aesthetics are impaired. Accordingly, in consideration of the height h of the ridge 6, the ranges of the region R1 ′ and the region R2 ′ are appropriate values (preferably about 20 ° or more), and the ranges of the region R3 ′ and the region R4 ′ are appropriate. The number of chain knitting rows 2e is determined so that the value (preferably 40 ° or more) is obtained and the interval 1 between the ridges 6 is about 1.5 mm to 4 mm (about 3 to 5 knitting needles). Is preferred.
　［第３の経編地］
　次に、図１７を参照しつつ、第３の経編地５１について、以下説明する。尚、上記と同様に、経編地１と同一の構成については、同一の符号を付し、その詳細な説明は省略する。また、図１７においても、基部２の鎖編み列２ａ，２ｂの図示を省略した。 [Third warp knitted fabric]
Next, the third warp knitted fabric 51 will be described below with reference to FIG. In the same manner as described above, the same components as those of the warp knitted fabric 1 are denoted by the same reference numerals, and detailed description thereof is omitted. Also in FIG. 17, illustration of the chain knitting rows 2 a and 2 b of the base 2 is omitted.
　図１７に示すように、第３の経編地５１は、前記基部２の連結部２ｄに鎖編み列２ｅを編成するとともに、当該鎖編み列２ｅを含む鎖編み列２ａ，２ｂ，２ｅの一部と、これらの近傍に位置する他の鎖編み列２ａ，２ｂ，２ｅの一部とが、基部２の連結部２ｄが所謂メッシュ状となるように、ウェール方向において複数の連結糸２ｃにより連結され編成されている。尚、鎖編み列２ｅは、図１７において実線で示した。 As shown in FIG. 17, the third warp knitted fabric 51 knits a chain knitting row 2e on the connecting portion 2d of the base 2 and one of the chain knitting rows 2a, 2b, 2e including the chain knitting row 2e. And a portion of the other chain knitting rows 2a, 2b, 2e located in the vicinity thereof are connected by a plurality of connecting yarns 2c in the wale direction so that the connecting portion 2d of the base portion 2 has a so-called mesh shape. Is organized. The chain stitch row 2e is indicated by a solid line in FIG.
　この経編地５１は、経編地１と同様に、当該経編地５１を見る際の観察者の位置に応じて色彩が変化する色彩効果を奏し、また、基部２の連結部２ｄをメッシュ状にすることで、経編地５１自体の軽量化を図ることができ、当該経編地５１によって靴のアッパーを形成することで、容易に通気性を確保することができる。 Similar to the warp knitted fabric 1, the warp knitted fabric 51 has a color effect in which the color changes depending on the position of the observer when viewing the warp knitted fabric 51, and the connecting portion 2d of the base 2 is meshed. By making it into a shape, it is possible to reduce the weight of the warp knitted fabric 51 itself, and by forming the upper of the shoe with the warp knitted fabric 51, air permeability can be easily ensured.
　［第４の経編地］
　ついで、第４の経編地６１について、図１８を参照しつつ、以下説明する。尚、以下の説明においても上記と同様に、経編地１と同一の構成については、同一の符号を付し、その詳細な説明は省略する。 [Fourth knitted fabric]
Next, the fourth warp knitted fabric 61 will be described below with reference to FIG. In the following description, similarly to the above, the same components as the warp knitted fabric 1 are denoted by the same reference numerals, and detailed description thereof is omitted.
　図１８に示すように、この経編地６１は、上記経編地１，４１，５１と異なり、基部２の連結部２ｄにループからなる編み列２ｆを連結糸２ｃによって形成しつつ、連結糸２ｃを側壁部４，５の各鎖編み列４ａ，５ａに結接し、基部２の連結部２ｄがメッシュ状となるように編成されている。 18, the warp knitted fabric 61 is different from the warp knitted fabrics 1, 41, 51 in that the connecting yarn 2c forms a knitting row 2f consisting of loops in the connecting portion 2d of the base portion 2, and the connecting yarn 2c. 2c is connected to each chain braid row 4a, 5a of the side wall portions 4, 5, and the connecting portion 2d of the base portion 2 is knitted so as to have a mesh shape.
　この経編地６１についても、前記経編地５１と同様に、観察者が当該経編地６１を見る際の位置に応じて色彩が変化する色彩効果を発揮し、また、連結部２ｄをメッシュ状としたことによって、編地自体の軽量化が図れ、当該経編地５１を靴のアッパーに使用することで、容易に通気性を確保することができる。 As with the warp knitted fabric 51, the warp knitted fabric 61 also exhibits a color effect in which the color changes depending on the position when the observer views the warp knitted fabric 61, and the connecting portion 2d is meshed. Thus, the weight of the knitted fabric itself can be reduced, and by using the warp knitted fabric 51 as an upper of a shoe, air permeability can be easily ensured.
　［第５の経編地］
　次に、第５の経編地７１について、図１９を参照しつつ、以下説明する。尚、上記と同様に、経編地１と同一の構成については、同一の符号を付し、その詳細な説明を省略する。また、図１９においては、基部２全体の図示を省略した。 [Fifth warp knitted fabric]
Next, the fifth warp knitted fabric 71 will be described below with reference to FIG. In the same manner as described above, the same components as those of the warp knitted fabric 1 are denoted by the same reference numerals, and detailed description thereof is omitted. In FIG. 19, the entire base 2 is not shown.
　この経編地７１は、図１９に示すように、各凸条部６の頂部３の一部と、これと隣接する他の凸条部６の頂部３の一部との間を、複数の連結糸７によって連結し、頂部３とほぼ同じ高さの平面内にメッシュ状の組織を形成するように編成されている。尚、前記連結糸７は、有色糸であることが好ましい。また、連結糸７は、図１９において点線で示した。 As shown in FIG. 19, the warp knitted fabric 71 includes a plurality of portions between a part of the top part 3 of each ridge part 6 and a part of the top part 3 of another ridge part 6 adjacent thereto. They are knitted so as to form a mesh-like structure in a plane which is connected by the connecting yarn 7 and is almost the same height as the top 3. The connecting yarn 7 is preferably a colored yarn. The connecting yarn 7 is indicated by a dotted line in FIG.
　この経編地７１においては、頂部３とほぼ同じ高さの平面内にメッシュ状の組織が形成されていることにより、観察者によって、メッシュの開口部分を通して凸条部６が視認されるようになるため、メッシュ状の組織がない場合と比較して、複雑な模様を表現することができる。また、凸条部６が他の凸条部６と連結された状態となっているため、凸条部６の形状安定性をより高めることができる。 In this warp knitted fabric 71, the mesh-like structure is formed in a plane that is almost the same height as the top 3, so that the ridge 6 can be visually recognized by the observer through the opening of the mesh. Therefore, a complicated pattern can be expressed as compared with the case where there is no mesh-like structure. Moreover, since the protruding item | line part 6 is in the state connected with the other protruding item | line part 6, the shape stability of the protruding item | line part 6 can be improved more.
　尚、この第５の経編地７１においては、頂部３同士を連結する複数の連結糸７によって、幅広の編み領域を編成し、頂部３とほぼ同じ高さの平面内に、切れ目（小さな開口部）を有する編み組織を形成するようにしても良い。 In the fifth warp knitted fabric 71, a wide knitting region is knitted by a plurality of connecting yarns 7 that connect the top portions 3 to each other, and a cut (small opening) is formed in a plane that is almost the same height as the top portion 3. Part) may be formed.
　図２０は、上記のような切れ目８１ａを有する編み組織が形成された経編地８１をアッパー材に用いた靴４０を示す図である。同図２０に示すように、この靴４０は、アッパー１２の母趾球部、小趾球部、前足部、中足部及び後足部を含む、外皮のほぼ全体に経編地８１が用いられている。 FIG. 20 is a view showing a shoe 40 using, as an upper material, a warp knitted fabric 81 in which a knitted structure having a cut 81a as described above is formed. As shown in FIG. 20, this shoe 40 uses a warp knitted fabric 81 for almost the entire outer skin, including the base ball portion, the small ball portion, the front foot portion, the middle foot portion, and the rear foot portion of the upper 12. It has been.
　そして、この靴４０においては、複数の連結糸７によって編成された幅広の編み領域が観察者に視認されるとともに、凸条部６の頂部３及び側壁部４，５が前記切れ目８１ａを通して視認されるため、その美観が、幅広の編み領域が編成されていないものとは異なったものとなる。また、前記連結糸７の色、頂部３の鎖編み列３ａ，３ｂ及び各側壁部４，５の鎖編み列４ａ，５ａの編糸の色の組み合わせを変えることで、外観が大きく変化する。したがって、経編地８１によってアッパー１２を形成することで、靴の外観に容易に多様性を持たせることができる。また、幅広の編み領域が編成されていないものと比べて、フィット性をより一層向上させることができる。 In the shoe 40, the wide knitting region knitted by the plurality of connecting yarns 7 is visually recognized by the observer, and the top 3 and the side walls 4, 5 of the ridge 6 are visually recognized through the cut 81a. Therefore, the aesthetics are different from those in which the wide knitting area is not knitted. Further, by changing the combination of the color of the connecting yarn 7 and the color of the knitting yarns of the chain knitting rows 3a and 3b of the top portion 3 and the chain knitting rows 4a and 5a of the side wall portions 4 and 5, the appearance changes greatly. Therefore, by forming the upper 12 with the warp knitted fabric 81, the appearance of the shoes can be easily varied. In addition, the fit can be further improved as compared with the case where the wide knitting region is not knitted.
　尚、本発明に係る靴のアッパーに用いられる経編地が採り得る態様は何らこれらに限定されるものではない。 In addition, the aspect which the warp knitted fabric used for the upper of the shoes concerning this invention can take is not limited to these at all.
　例えば、上述した各経編地１，４１，５１，６１，７１，８１において、頂部３を構成する鎖編み列３ａ，３ｂを第１色の編糸、一方の側壁部４を構成する鎖編み列４ａを第２色の編糸、他方の側壁部５を構成する鎖編み列５ａを第３色の編糸で編成し、頂部３及び各側壁部４，５にそれぞれ異なる色を配置するようにしているが、これに限られるものではなく、頂部３及び各側壁部４，５のうち、いずれか１つが他の部分と異なる色となるようにすれば良い。 For example, in each of the above-described warp knitted fabrics 1, 41, 51, 61, 71, 81, the chain knitting rows 3a, 3b constituting the top portion 3 are the knitting yarns of the first color and the chain knitting constituting the one side wall portion 4. The row 4a is knitted with the second color knitting yarn, the chain knitting row 5a constituting the other side wall 5 is knitted with the third color knitting yarn, and different colors are arranged on the top 3 and the side walls 4, 5 respectively. However, the present invention is not limited to this, and any one of the top portion 3 and the side wall portions 4 and 5 may have a different color from the other portions.
　具体的に言えば、頂部３及び側壁部４を構成する各鎖編み列３ａ，３ｂ，４ａを第１色の編糸によって編成し、側壁部５を構成する鎖編み列５ａを第２色の編糸によって編成するようにしても良い。この場合、観察者が側壁部４側から経編地を見ると、第１色のみが視認され、側壁部５側から見ると、第１及び第２色が視認される。 Specifically, each chain knitting row 3a, 3b, 4a constituting the top portion 3 and the side wall portion 4 is knitted with the first color knitting yarn, and the chain knitting row 5a constituting the side wall portion 5 is knitted with the second color. You may make it knit by a knitting yarn. In this case, when the observer sees the warp knitted fabric from the side wall 4 side, only the first color is visually recognized, and when viewed from the side wall 5 side, the first and second colors are visible.
　また、頂部３の鎖編み列３ａ，３ｂを第１色の編糸によって編成し、各側壁部４，５の鎖編み列４ａ，５ａを第２色の編糸で編成するようにしても良く、この場合には、観察者が各側壁部４，５側から経編地を見ると、第１及び第２色が視認され、経編地を正面から見ると、ほぼ第１色のみが視認される。 Alternatively, the chain knitting rows 3a and 3b of the top portion 3 may be knitted with the first color knitting yarn, and the chain knitting rows 4a and 5a of the side wall portions 4 and 5 may be knitted with the second color knitting yarn. In this case, when the observer sees the warp knitted fabric from the side walls 4 and 5, the first and second colors are visually recognized, and when the warp knitted fabric is viewed from the front, only the first color is visually recognized. Is done.
　このように、頂部３及び各側壁部４，５のうち、いずれか１つが他の部分と異なる色となるようにすれば、編み立て方向と交差する方向から経編地を見るときの観察者の位置に応じて色彩が変化するという色彩効果を発揮させることが可能である。 In this way, if any one of the top part 3 and the side wall parts 4 and 5 has a different color from the other parts, the observer can see the warp knitted fabric from the direction intersecting the knitting direction. It is possible to exhibit a color effect that the color changes according to the position of the color.
　また、各経編地１，４１，５１，６１，７１，８１においては、２本の鎖編み列３ａ，３ｂを連結糸３ｃによって連結して頂部３を編成するようにしているが、頂部３を構成する鎖編み列の数は、これに限られるものではなく、頂部３は、３列以上の鎖編み列を連結糸によって連結して編成しても良い。 Further, in each warp knitted fabric 1, 41, 51, 61, 71, 81, two chain knitting rows 3a, 3b are connected by a connecting yarn 3c to knit the top 3, but the top 3 The number of chain knitting rows constituting the knitting is not limited to this, and the top portion 3 may be knitted by connecting three or more chain knitting rows with connecting yarns.
　更に、上記各経編地１，４１，５１，６１，７１，８１においては、連結糸２ｃとして透明糸を用いるようにしているが、これに限られるものではなく、有色糸であっても良い。 Further, in each of the warp knitted fabrics 1, 41, 51, 61, 71, 81, a transparent yarn is used as the connecting yarn 2c. However, the present invention is not limited to this, and a colored yarn may be used. .
