　ＪＰ２００６－２５８Ａでは、帯状部が内皮に形成されているが、帯状部を外皮に形成することは開示されていない。 JP 2006-258A has a band-shaped part formed on the inner skin, but does not disclose that the band-shaped part is formed on the outer skin.
　ＪＰ２０００－２１０１０１Ａには、帯状部および貫通孔を有するアッパーが開示されているが、上下方向に長いスリットについては開示されていない。 JP2000-210101A discloses an upper having a strip portion and a through-hole, but does not disclose a slit that is long in the vertical direction.
　ＪＰ２００９－２４０８２７Ａには、アッパーの長手方向に延びる複数の切込みを有するアッパーが開示されているが、上下方向に長いスリットについては開示されていない。 JP2009-240827A discloses an upper having a plurality of cuts extending in the longitudinal direction of the upper, but does not disclose a slit that is long in the vertical direction.
　ＪＰ２００８－５４３４５２Ａには、互いにクロスして孔を規定するマトリクス構造を開示しているが、孔の幅がマトリクスの部位よりも小さい構造を開示していない。また、同文献には織布などの布帛にスリットを有するアッパーは開示されていない。 JP2008-543442A discloses a matrix structure that defines holes by crossing each other, but does not disclose a structure in which the width of the holes is smaller than the portion of the matrix. Further, this document does not disclose an upper having a slit in a fabric such as a woven fabric.
文献ＪＰ５，９８６，７００Ｂ２には細長いスリット状の多数の貫通孔が形成された外皮（柔軟材）が開示されており、この外皮を織物又は編物で形成することが開示されている。しかし、同文献は外皮が上下に伸びることを狙っている。たとえば、貫通孔の幅に対し、帯状部の幅が大きい外皮は開示されていない。また、貫通孔の周囲において織物の繊維同士を互いに溶着構造等で固着することは開示されていない。また、外皮は織構造の内皮よりも伸び易いだろう。 Document JP5,986,700B2 discloses an outer skin (soft material) in which a large number of elongated slit-like through holes are formed, and it is disclosed that the outer skin is formed of a woven fabric or a knitted fabric. However, the document aims to make the outer skin extend vertically. For example, an outer skin in which the width of the belt-like portion is larger than the width of the through hole is not disclosed. Moreover, it is not disclosed that the fibers of the fabric are fixed to each other with a welded structure or the like around the through hole. The outer skin will also be easier to stretch than the woven endothelium.
　本発明の目的は足の側面にアッパーがフィットし易い靴を提供することである。 An object of the present invention is to provide a shoe in which the upper easily fits to the side of the foot.
第１局面において、本発明は、アッパー１、締付部材およびソール２を有する靴であって、前記アッパー１は、
前記締付部材が係合する係合部３と、
前記係合部３と前記ソール２との間の領域において足の側面を覆うように構成された外皮４とを備え、
前記外皮４は前記係合部３と前記ソール２との間において延び前縁５ｆおよび後縁５ｂで規定された複数のバンド状部５を有し、
　前記複数のバンド状部５は互いに隣り合う爪先側のバンド状部５ｉと踵側のバンド状部５ｉ＋１とを包含し、
　前記爪先側のバンド状部５ｉの前記後縁５ｂと、前記踵側のバンド状部５ｉ＋１の前記前縁５ｆとは前記両バンド状部の間においてスリット７を規定する。 In the first aspect, the present invention is a shoe having an upper 1, a fastening member and a sole 2, wherein the upper 1
An engaging portion 3 with which the tightening member engages;
An outer skin 4 configured to cover a side surface of a foot in a region between the engagement portion 3 and the sole 2;
The outer skin 4 has a plurality of band-shaped parts 5 extending between the engaging part 3 and the sole 2 and defined by a front edge 5f and a rear edge 5b,
The plurality of band-like parts 5 include a band-like part 5 i on the toe side and a band-like part 5 i + 1 on the heel side that are adjacent to each other,
And the trailing edge 5b of the band-shaped portion 5 i of the toe-side, and the front edge 5f of the band-shaped portion 5 i + 1 of the heel-side to define a slit 7 between the two band-section.
第１局面において、足の変形時に、スリット７はバンド状部間の応力の伝達を抑制するだろう。そのため、バンド状部に皺が発生しにくく、足の側面にアッパーがフィットし易いだろう。 In the first aspect, when the foot is deformed, the slit 7 will suppress the transmission of stress between the band-like portions. Therefore, wrinkles are unlikely to occur in the band-shaped portion, and the upper will easily fit on the side of the foot.
ところで、各バンド状部が互いに独立した構造である場合、外皮を所定の形状にするのに手間や工数が増加する。例えば、互いに分離した状態の各バンド状部の上端部をハトメ飾りに縫い合わせるのは面倒である。 By the way, when each band-like part is a structure independent from each other, labor and man-hours increase to make the outer skin a predetermined shape. For example, it is troublesome to sew the upper ends of the band-shaped parts separated from each other to the eyelet decoration.
また、各バンド状部ごとに前記係合部を設けて各バンド状部ごとに締め付けを行う場合、締め付けのための係合部の間隔とバンド状部の間隔を同一に設定する必要がある。この場合、アッパーの設計やデザインの自由度が大きく阻害される。 Moreover, when the said engaging part is provided for every band-like part and it clamps for every band-like part, it is necessary to set the space | interval of the engaging part for fastening, and the space | interval of a band-like part equally. In this case, the upper design and the degree of freedom of design are greatly hindered.
こうした問題を解決するために、第１局面において好ましくは、前記外皮４は、
　前記ソール２側において前記互いに隣り合うバンド状部５ｉ，５ｉ＋１の各々に一体に連なる第１部４１と、
　前記係合部３側において前記互いに隣り合うバンド状部５ｉ，５ｉ＋１の各々に一体に連なる第２部４２とを更に備え、
　前記外皮４は、前記第１部４１から前記爪先側のバンド状部５ｉ、前記第２部４２および前記踵側のバンド状部５ｉ＋１を介して前記第１部４１まで継目なく連なるループを形成している。 In order to solve such a problem, preferably in the first aspect, the outer skin 4 is:
A first portion 41 integrally connected to each of the band- like portions 5 i and 5 i + 1 adjacent to each other on the sole 2 side;
A second portion 42 integrally connected to each of the band- like portions 5 i and 5 i + 1 adjacent to each other on the engagement portion 3 side;
The outer skin 4 has a loop continuously extending from the first part 41 to the first part 41 through the band-like part 5 i on the toe side, the second part 42 and the band-like part 5 i + 1 on the heel side. Forming.
すなわち、この場合、前記ソール側および係合部側において前記互いに隣り合うバンド状部の各々に一体に連なる（have a unitary structure）第１部および第２部が設けられ、第１部、バンド状部および第２部を含む外皮は継目のないループを形成している。 That is, in this case, a first part and a second part are provided integrally with each of the band-like parts adjacent to each other on the sole side and the engaging part side, and the first part and the band-like part are provided. The outer skin including the part and the second part forms a seamless loop.
かかる継目のないループを形成した外皮は製造が容易であろう。
また、係合部側に第２部が設けられていることで、バンド状部の数は係合部の数に支配されず、自由に設定される。すなわち、バンド状部の配置の自由度が得られるだろう。 Such a skin with seamless loops would be easy to manufacture.
In addition, since the second part is provided on the engaging part side, the number of band-like parts is not controlled by the number of engaging parts, and can be set freely. That is, a degree of freedom in arrangement of the band-like portion will be obtained.
第２局面において、本発明は、アッパー１、締付部材およびソール２を有する靴であって、前記アッパー１は、
　前記締付部材が係合する係合部３と、
　前記係合部３と前記ソール２との間の領域において足の側面を覆うように構成された外皮４とを備え、前記外皮４は上下方向Ｙに延びる複数本のスリット７を規定し、
　前記複数本のスリット７は前後方向Ｘに互いに離間しており、
　前記外皮４は
　前記複数本のスリット７により前記前後方向Ｘに互いに分断された少なくとも３本のバンド状部５と、
　前記３本のバンド状部５の下方において前記ソール２に沿って前記前後方向Ｘに延び前記３本のバンド状部５に一体に連なる第１部４１と、
　前記３本のバンド状部５の上方において前記係合部３に沿って前記前後方向Ｘに延び前記３本のバンド状部５に一体に連なる第２部４２と、を有する。 In the second aspect, the present invention is a shoe having an upper 1, a fastening member and a sole 2, wherein the upper 1
An engaging portion 3 with which the tightening member engages;
An outer skin 4 configured to cover the side surface of the foot in a region between the engagement portion 3 and the sole 2, the outer skin 4 defining a plurality of slits 7 extending in the vertical direction Y;
The plurality of slits 7 are separated from each other in the front-rear direction X,
The outer skin 4 has at least three band-like parts 5 separated from each other in the front-rear direction X by the plurality of slits 7;
A first portion 41 that extends in the front-rear direction X along the sole 2 below the three band-shaped portions 5 and is integrally connected to the three band-shaped portions 5;
A second portion 42 that extends in the front-rear direction X along the engagement portion 3 above the three band-shaped portions 5 and that is integrally connected to the three band-shaped portions 5.
第２局面において、３本のスリット７により前後方向に分断されたバンド状部間には、足の変形時に、応力の伝達が生じにくいだろう。そのため、バンド状部に皺が発生しにくく、足の側面にアッパーがフィットし易いだろう。 In the second phase, between the band-shaped portions divided in the front-rear direction by the three slits 7, stress transmission will hardly occur when the foot is deformed. Therefore, wrinkles are unlikely to occur in the band-shaped portion, and the upper will easily fit on the side of the foot.
第２局面においても継目のないループを形成した外皮は製造が容易であろう。
また、係合部側に第２部が設けられていることで、バンド状部の配置の自由度が得られるだろう。 Even in the second aspect, the outer skin formed with a seamless loop will be easy to manufacture.
In addition, since the second portion is provided on the engagement portion side, the degree of freedom of arrangement of the band-shaped portion will be obtained.
本発明において、締付部材とは、アッパーを締め付けて足にフィットさせるための部材を意味し、シューレースの他、ベルトやファスナであってもよい。 In the present invention, the tightening member means a member for tightening the upper to fit the foot, and may be a belt or a fastener other than a shoe race.
本発明において、係合部とは、例えば、シューレースを通すハトメやループ、あるいは、シューレースが係合するＵ管であってもよい。 In the present invention, the engaging portion may be, for example, a eyelet or a loop through which a shoe race passes, or a U tube with which the shoe race engages.
本発明において、スリットとはスリットの長さに比べスリットの幅が小さい貫通孔を意味する。 In the present invention, the slit means a through hole having a slit width smaller than the slit length.
好ましくは、スリットの長さはスリットの幅の２倍以上に設定される。
この場合、スリットによる外皮の欠損が小さく、外皮に必要な強度を得易いだろう。 Preferably, the length of the slit is set to be twice or more the width of the slit.
In this case, the loss of the outer skin due to the slit is small, and the strength required for the outer skin will be easily obtained.
本発明において、“前後方向”とは、靴の長手方向および長手方向に対して斜めである斜め前後方向を含むことを意味する。 In the present invention, the “front-rear direction” means including the longitudinal direction of the shoe and the oblique front-rear direction that is oblique to the longitudinal direction.
本発明において、“上下方向”とは、前後方向Ｘに直交し、かつ、ソールの接地面に交差する方向（鉛直方向等）を含み、鉛直方向に対し斜めである方向を含む。 In the present invention, the “vertical direction” includes a direction (vertical direction or the like) that is orthogonal to the front-rear direction X and intersects the ground contact surface of the sole, and includes a direction that is oblique to the vertical direction.
すなわち、“上下方向に延びる複数本のスリット”とは、少なくとも２本のスリットについて、スリットとソールの接地面とのなす角αが４５°～９０°の範囲であることを意味する。前記スリットが３本以上設けられている場合に、一部のスリットについては、前記角αが４５°未満であってもよい。 That is, “a plurality of slits extending in the vertical direction” means that the angle α formed by the slit and the ground contact surface of the sole is in the range of 45 ° to 90 ° for at least two slits. When three or more slits are provided, the angle α may be less than 45 ° for some of the slits.
上下方向に延びるスリットは直線状である必要はなく、たとえばＳ字状などであってもよい。 The slit extending in the vertical direction does not need to be linear, and may be, for example, S-shaped.
“一体に連なる(have a unitary structure)” とは、外皮の単一の素材に複数本のスリットにより少なくとも３本のバンド状部が形成されていることを意味する。すなわち、３本のバンド状部、第１部および第２部は外皮の単一の素材に形成されて、互いに継目なく連なっている。 “Having a unitary structure” means that at least three band-like portions are formed by a plurality of slits in a single material of the outer skin. That is, the three band-shaped parts, the first part and the second part are formed in a single material of the outer skin and are continuously connected to each other.
バンド状部は締付部材の締付力により足をホールドするものであるから、本質的に伸び難い素材で形成されているのが好ましい。 Since the band-shaped portion holds the foot by the tightening force of the tightening member, the band-shaped portion is preferably formed of a material that is essentially difficult to stretch.
かかる観点から、第１部、第２部およびバンド状部は、例えば、織構造を有する織布で形成されてもよい。 From this viewpoint, the first part, the second part, and the band-shaped part may be formed of a woven fabric having a woven structure, for example.
例えば、前記外皮４およびスリット７を内から覆い足の表面に接するように構成された内皮８を前記アッパー１が更に備えている場合、好ましくは、
前記バンド状部５が延びる方向について、前記外皮４は前記内皮８よりも伸びにくい布帛で形成されている。 For example, when the upper 1 further includes the inner skin 8 configured to cover the outer skin 4 and the slit 7 from the inside and come into contact with the surface of the foot, preferably,
In the direction in which the band-shaped portion 5 extends, the outer skin 4 is formed of a fabric that is less likely to extend than the inner skin 8.

図１、図２および図９および図１１において、織布の部位には格子模様が付され、ホットメルトフィルムの部位には密度の粗いドット模様が付され、スリットを通して見える内皮の部位には密度の濃いドット模様が付されている。 1, 2, 9, and 11, a lattice pattern is attached to the woven fabric portion, a dot pattern with a coarse density is attached to the hot melt film portion, and the density is applied to the endothelium portion that can be seen through the slit. A dark dot pattern is attached.
図３（ａ）、図４、図７（ａ）および図１３（ａ）において、作図の便宜上、各スリットの端部は矩形状に図示されている。 In FIG. 3A, FIG. 4, FIG. 7A, and FIG. 13A, for convenience of drawing, the end of each slit is shown in a rectangular shape.
　好ましくは、前記外皮４は複数の繊維Ｆで形成された布帛Ｔを含み、前記各バンド状部５は前記スリット７を規定する前後の縁５ｆ，５ｂを有し、
　前記各縁において、前記繊維Ｆ同士が溶着構造Ｗｃにより互いに固定されている。 Preferably, the outer skin 4 includes a fabric T formed of a plurality of fibers F, and each band-like portion 5 has front and rear edges 5f and 5b that define the slit 7,
At each edge, the fibers F are fixed to each other by a welding structure Wc.
　外皮がカッターナイフのような機械的な切断機で切断されて前記スリットが形成されている場合、バンド状部の縁において繊維の組織がバラけてくるだろう。その場合、バンド状部が経時的に劣化し易いだろう。また、スリットの輪郭がぼやけて見えるだろう。 When the outer skin is cut by a mechanical cutter such as a cutter knife to form the slit, the fiber structure will be scattered at the edge of the band-shaped part. In that case, the band-shaped portion will easily deteriorate over time. Also, the outline of the slit will appear blurred.
　これに対し、繊維Ｆ同士が溶着構造（welding construction）により互いに固定されている場合、バンド状部の縁において繊維の組織がバラけにくいだろう。その場合、バンド状部が経時的に劣化しにくいだろう。また、スリットの輪郭がくっきりと見え外観が向上するだろう。 On the other hand, when the fibers F are fixed to each other by a welding construction, the structure of the fibers will not easily vary at the edge of the band-shaped part. In that case, the band-shaped portion will hardly deteriorate over time. In addition, the outline of the slit will be clear and the appearance will be improved.
　好ましくは、前記外皮４は布帛Ｔと樹脂フィルムＬとの積層構造を有し、
　前記布帛Ｔは複数本の繊維Ｆを含み、
　前記各バンド状部５は前記スリット７を規定する前後の縁５ｆ，５ｂを有し、
　前記各縁５ｆ，５ｂにおいて、前記繊維Ｆと前記樹脂フィルムＬとが溶着構造Ｗｃにより互いに固定されている。 Preferably, the outer skin 4 has a laminated structure of the fabric T and the resin film L,
The fabric T includes a plurality of fibers F,
Each band-like portion 5 has front and rear edges 5f and 5b that define the slit 7,
At each of the edges 5f and 5b, the fiber F and the resin film L are fixed to each other by a welding structure Wc.
この場合も、溶着構造による同様の効果が得られるであろう。 In this case, the same effect by the welded structure will be obtained.
　好ましくは、前記外皮４は、
前記第１部４１の一部または全部を被覆している第１シート部Ｌ１と、
　前記第２部４２の一部または全部を被覆している第２シート部Ｌ２とを更に備える。 Preferably, the outer skin 4 is
A first sheet portion L1 covering a part or all of the first portion 41;
And a second sheet portion L2 that covers a part or all of the second portion.
　この場合、第１および第２シート部は、それぞれ、第１部および第２部を補強するであろう。すなわち、“被覆”とは付着という程度の意味で、ラミネートや縫い合わせを含む意味である。 In this case, the first and second sheet portions will reinforce the first and second portions, respectively. That is, “covering” means a degree of adhesion and includes lamination and sewing.
　より詳しくは、「付着」とは、固着という言葉に置き換えてもよく、概念的には容易に取り外しができないように接合されていることを意味する。また、具体的には「付着」とは、接着、溶着、プリントまたは縫合（縫着）などの手段や、これらの２以上の手段を組み合わせて接合することを意味する。 More specifically, “adhesion” may be replaced with the term “adherence”, and conceptually means that it is joined so that it cannot be easily removed. Further, specifically, “attachment” means means such as adhesion, welding, printing or stitching (sewing), or a combination of these two or more means.
　ここで、第１部および第２部を被覆している第１および第２シート部には、不織布シートや非伸性のテープ材で構成されたハトメ飾りや補強材が含まれる。 Here, the first and second sheet parts covering the first part and the second part include eyelet decorations and reinforcing materials made of a non-woven sheet or a non-extensible tape material.
　より好ましくは、前記外皮４は、
前記第１部４１の一部または全部をラミネートしている第１シート部Ｌ１と、
　前記第２部４２の一部または全部をラミネートしている第２シート部Ｌ２とを更に備える。 More preferably, the outer skin 4 is
A first sheet portion L1 laminating part or all of the first portion 41;
And a second sheet portion L2 in which a part or all of the second portion 42 is laminated.
この場合、第１部および第２部をラミネートしている第１および第２シート部は、第１部および第２部を強化する。そのため、スリットが経時的に第１部および第２部に延びていくのが抑制される。 In this case, the first and second sheet parts laminating the first part and the second part reinforce the first part and the second part. Therefore, it is suppressed that the slit extends to the first part and the second part over time.
　“ラミネートしている”とは、部材が単に重なっているだけでなく、１つの部材が他の部材に溶着されて積層されていることを意味する。即ち、“ラミネートしている”とは、溶着構造により積層されていることを意味する。 “Laminating” means that the members are not only overlapped but one member is welded and laminated to the other. That is, “laminated” means that they are laminated by a welded structure.
前記第１および第２シート部を構成する素材としては、例えば、いわゆるホットメルトシートを好的に採用することができる。ホットメルトシートとは、熱可塑性の樹脂シートで、昇温されることで、容易に第１部または第２部に溶着することができる。 As a material constituting the first and second sheet portions, for example, a so-called hot melt sheet can be preferably used. The hot melt sheet is a thermoplastic resin sheet, and can be easily welded to the first part or the second part by raising the temperature.
好ましくは、前記第１シート部Ｌ１は前記バンド状部５の下端部５５を覆うと共に前記スリット７の下端部７５を埋め、
前記第２シート部Ｌ２は前記バンド状部５の上端部５０を覆うと共に前記スリット７の上端部７０を埋める。 Preferably, the first sheet portion L1 covers the lower end portion 55 of the band-like portion 5 and fills the lower end portion 75 of the slit 7;
The second sheet portion L2 covers the upper end portion 50 of the band-shaped portion 5 and fills the upper end portion 70 of the slit 7.
この場合、バンド状部の上端部や下端部が露出しておらず、そのため、スリットの端から破れが生じるのを抑制できるだろう。 In this case, the upper end portion and the lower end portion of the band-shaped portion are not exposed, so that it is possible to suppress the tearing from occurring at the end of the slit.
好ましくは、前記外皮４は前記係合部３の補強材６を有し、
前記補強材６は前記第２部４２の一部をラミネートしている。
この場合、第２部が更に強化され、係合部および第２部を介して各バンド状部に伝達される締付力はバンド状部ごとに大きなバラツキが生じにくいだろう。すなわち、複数のバンド状部のうちの１つのバンド状部に大きな負荷が生じにくいだろう。 Preferably, the outer skin 4 has a reinforcing member 6 for the engaging portion 3.
The reinforcing member 6 is laminated on a part of the second portion 42.
In this case, the second part is further strengthened, and the tightening force transmitted to each band-like part via the engaging part and the second part will not easily vary greatly from band to part. That is, a large load is unlikely to occur in one of the plurality of band portions.
好ましくは、前記アッパー１は前記外皮４およびスリット７を内から覆い足の表面に接するように構成された内皮８を更に備え、
前記内皮８と前記外皮４のバンド状部５とが互いに非接着である。 Preferably, the upper 1 further comprises an inner skin 8 configured to cover the outer skin 4 and the slit 7 from the inside and to contact the surface of the foot,
The inner skin 8 and the band-like portion 5 of the outer skin 4 are not adhered to each other.
歩行や走行により足は変形する。この足の変形に応じて各スリットの形状が変化する。ここで、外皮を内から覆う内皮は前記スリットを通して視認される。そのため、歩行や走行によりスリットを通して見える内皮の領域が変化する。これにより、動的な美観の向上が図られる。 The legs are deformed by walking and running. The shape of each slit changes according to the deformation of the foot. Here, the inner skin covering the outer skin from the inside is visually recognized through the slit. Therefore, the region of the endothelium that can be seen through the slit changes when walking or running. Thereby, the dynamic aesthetics are improved.
好ましくは、バンド状部５が延びる方向について、外皮４は内皮８よりも伸びにくい布帛で形成される。この場合、外皮の締付力で内皮が足にフィットし易いだろう。 Preferably, the outer skin 4 is formed of a fabric that is less likely to extend than the inner skin 8 in the direction in which the band-shaped portion 5 extends. In this case, the inner skin will easily fit the foot due to the tightening force of the outer skin.
好ましくは、前記アッパー１は前記外皮４を２枚包含し、
前記２枚の外皮４が内足または外足の少なくとも一方の側面において互いに重なっている。 Preferably, the upper 1 includes two outer skins 4,
The two outer skins 4 overlap each other on at least one side of the inner foot or the outer foot.
この場合、好ましくは、２枚の外皮の各々のベルト状部が互いに立体的に交差するように配置してもよい。これにより、靴の種別（競技）に応じた足のホールド機能を発揮することができる。例えばバンド状部の過大な変形による棚落ちを抑制できる。 In this case, preferably, the belt-like portions of the two outer skins may be arranged so as to three-dimensionally intersect each other. Thereby, the hold function of the foot | leg according to the classification (competition) of shoes can be exhibited. For example, shelves can be prevented from dropping due to excessive deformation of the band-shaped portion.
好ましくは、前記バンド状部５の幅５ｗの平均値が前記スリット７の幅７ｗの平均値の２倍以上である。 Preferably, the average value of the width 5w of the band-shaped portion 5 is twice or more the average value of the width 7w of the slit 7.
この場合、スリットによる外皮の欠損が抑制され、バンド状部に対する負荷が小さい。 In this case, the loss of the outer skin due to the slit is suppressed, and the load on the band-shaped portion is small.
好ましくは、前記スリットの長さ７ｌが前記バンド状部５の幅５ｗの平均値よりも大きい。 Preferably, the length 7 l of the slit is larger than the average value of the width 5 w of the band-like portion 5.
スリットの長さが長い場合、バンド状部の長さも長い。長さの長いバンド状部は足沿いを向上させるかもしれない。なお、バンド状部の長さよりもスリットの長さの方が測定し易いため、スリットの長さとバンド状部の幅とを比較する。 When the length of the slit is long, the length of the band-shaped part is also long. Longer bands may improve along the foot. Since the length of the slit is easier to measure than the length of the band-shaped portion, the length of the slit and the width of the band-shaped portion are compared.
好ましくは、前記スリット７の長さ７ｌが前記スリット７の幅７ｗの平均値の２倍以上である。 Preferably, the length 7 l of the slit 7 is at least twice the average value of the width 7 w of the slit 7.
この場合、幅よりも長さが大きいスリットは、前記応力を伝達しにくく、また、スリットによる強度低下を抑制するだろう。また、細長いスリットは前記動的な美観を更に向上させるだろう。 In this case, the slit having a length larger than the width is difficult to transmit the stress, and the strength reduction due to the slit will be suppressed. Also, the elongated slit will further improve the dynamic aesthetic.
好ましくは、前記スリット７と前記ソール２の接地面２２とのなす角αが４５°～９０°である。
前記角αが４５°よりも小さい場合、締付部材による締付力により足をホールドするバンド状部の機能が著しく低下するだろう。 Preferably, an angle α formed by the slit 7 and the ground contact surface 22 of the sole 2 is 45 ° to 90 °.
When the angle α is smaller than 45 °, the function of the band-shaped portion that holds the foot by the tightening force by the tightening member will be significantly deteriorated.
好ましくは、前記複数のバンド状部５のうち、前後方向Ｘに互いに隣り合うバンド状部５ｉ，５ｉ＋１の間に２本以上のスリット７，７が設けられ、
前記２本以上のスリット７，７が前記スリット７，７の延びる第１方向Ｄ１に離間して配置されていると共に、前記互いに隣り合うバンド状部５ｉ，５ｉ＋１が前記第１部４１と前記第２部４２との間の第３部４３において互いに前後方向Ｘに連なっている。 Preferably, two or more slits 7 and 7 are provided between the band- like portions 5 i and 5 i + 1 adjacent to each other in the front-rear direction X among the plurality of band-like portions 5.
The two or more slits 7 and 7 are spaced apart from each other in the first direction D1 in which the slits 7 and 7 extend, and the adjacent band- like portions 5 i and 5 i + 1 are connected to the first portion 41. The third portion 43 between the second portion 42 and the second portion 42 is continuous with the front-rear direction X.
この場合、隣り合うバンド状部同士が第３部において互いに連なっており、１つのバンド状部が外に向かって膨れるように曲がって、走行や歩行の障害になるのを抑制し得る。 In this case, the adjacent band-like portions are connected to each other in the third portion, and it is possible to suppress a single band-like portion from bending and becoming an obstacle to running and walking.
好ましくは、前記布帛Ｔは前記スリット７の延びる第１方向Ｄ１に沿って延びる第１の織糸Ｔ１群と、前記第１方向Ｄ１に交差する第２方向Ｄ２に沿って延びる第２の織糸Ｔ２群とを有する織布であり、前記織糸Ｔ１群と織糸Ｔ２群とが織構造を構成する。 Preferably, the fabric T includes a first woven yarn T1 group extending along a first direction D1 in which the slit 7 extends, and a second woven yarn extending along a second direction D2 intersecting the first direction D1. The woven fabric having a T2 group, and the woven yarn T1 group and the woven yarn T2 group constitute a woven structure.
織布は織糸の延びる方向に本質的に伸縮しにくく、両織糸に交差するバイヤス方向に伸縮し易い。したがって、スリットの延びる第１方向に織糸が延びている場合、バンド状部は当該第１方向に伸縮しにくいだろう。そのため、締付部材による締付力が外皮に伝わり易い。その結果、アッパーによる足の保持機能が発揮され易い。 The woven fabric is essentially hard to expand and contract in the direction in which the woven yarn extends, and easily expands and contracts in the bias direction intersecting the two woven yarns. Therefore, when the woven yarn extends in the first direction in which the slit extends, the band-shaped portion will not easily expand and contract in the first direction. Therefore, the tightening force by the tightening member is easily transmitted to the outer skin. As a result, the function of holding the foot by the upper is easily exhibited.

本発明は、添付の図面を参考にした以下の好適な実施例の説明からより明瞭に理解されるであろう。しかし、実施例および図面は単なる図示および説明のためのものであり、本発明の範囲を定めるために利用されるべきものではない。本発明の範囲は請求の範囲によってのみ定まる。添付図面において、複数の図面における同一の部品番号は、同一または相当部分を示す。 The invention will be more clearly understood from the following description of preferred embodiments with reference to the accompanying drawings, in which: However, the examples and drawings are for illustration and description only and should not be used to define the scope of the present invention. The scope of the present invention is defined only by the claims. In the accompanying drawings, the same part numbers in a plurality of drawings indicate the same or corresponding parts.
　実施例１：
　以下、本発明の実施例１が図１～図６Ａを参照して説明される。
　実施例１では、左足用の靴が例示される。
　図１に示す靴は、たとえば、競技用やランニング用の靴で、ソール２の上にはアッパー１が固定されている。前記アッパー１は図示しないシューレース（締付部材）が係合する係合部３を備えている。シューレースは係合部３に挿通され、アッパー１が足にフィットするようにアッパー１を締め付ける。なお、本発明の各実施例の説明においては、図面を見易くするために、シューレースの図示は省略している。 Example 1:
A first embodiment of the present invention will be described below with reference to FIGS. 1 to 6A.
In Example 1, a shoe for the left foot is exemplified.
The shoe shown in FIG. 1 is, for example, a shoe for competition or running, and an upper 1 is fixed on a sole 2. The upper 1 includes an engaging portion 3 with which a shoe race (clamping member) (not shown) is engaged. The shoelace is inserted through the engaging portion 3 and tightens the upper 1 so that the upper 1 fits the foot. In the description of each embodiment of the present invention, the illustration of shoelaces is omitted for easy understanding of the drawings.
ソール２はアッパー１の下に配置され路面に接地するものである。ソール２はゴム製のアウトソール２０の上にＥＶＡのような樹脂製の発泡体のミッドソール２１を備えていてもよい。 The sole 2 is disposed under the upper 1 and is grounded to the road surface. The sole 2 may include a resin-made foam midsole 21 such as EVA on a rubber outsole 20.
前記アッパー１は外皮４と内皮８とを備える。内皮８は履き口１３の前方において舌片１０に接合されている。前記内皮８や舌片１０の生地を構成する素材は合成繊維または天然繊維であってもよい。 The upper 1 includes an outer skin 4 and an inner skin 8. The endothelium 8 is joined to the tongue piece 10 in front of the mouth 13. The material constituting the inner skin 8 or the tongue piece 10 may be a synthetic fiber or a natural fiber.
図５の模式図に示すように、外皮４および内皮８はインソール９に接合されている。前記舌片１０や内皮８は柔軟性の高いメッシュ状の生地や編物で形成されていてもよい。内皮８は足の表面に接する。内皮８の一部は外皮４により外から包まれている。 As shown in the schematic diagram of FIG. 5, the outer skin 4 and the inner skin 8 are joined to the insole 9. The tongue piece 10 and the inner skin 8 may be formed of a highly flexible mesh-like fabric or knitted fabric. The endothelium 8 contacts the surface of the foot. A part of the endothelium 8 is enveloped from the outside by the outer skin 4.
本例の場合、図５の外皮４は織布（布帛の一例）Ｔと、樹脂フィルムＬとが部分的に積層されている。織布（織物）Ｔは熱可塑性の樹脂繊維からなる複数の織糸から構成されている。一方、樹脂フィルムＬは、いわゆるホットメルトシートのような熱可塑性の樹脂シートから構成されている。 In the case of this example, a woven fabric (an example of a fabric) T and a resin film L are partially laminated on the outer skin 4 of FIG. The woven fabric (woven fabric) T is composed of a plurality of woven yarns made of thermoplastic resin fibers. On the other hand, the resin film L is composed of a thermoplastic resin sheet such as a so-called hot melt sheet.
図１において前記外皮４の織布Ｔは前記係合部３と前記ソール２との間の領域において足の側面を覆うように構成されている。前記外皮４の織布Ｔには上下方向Ｙの例えば斜め上下方向に延びる複数本のスリット７が形成されている。 In FIG. 1, the woven fabric T of the outer skin 4 is configured to cover the side surface of the foot in a region between the engaging portion 3 and the sole 2. The woven fabric T of the outer skin 4 is formed with a plurality of slits 7 extending in the up-down direction Y, for example, in an oblique up-down direction.
前記複数本のスリット７は前後方向Ｘに互いに離間している。前記外皮４の織布Ｔは少なくとも３本のバンド状部５、第１部４１および第２部４２を備える。なお、バンド状部の符合は「５」または「５」に下付き文字を付して示す。 The plurality of slits 7 are separated from each other in the front-rear direction X. The woven fabric T of the outer skin 4 includes at least three band-shaped parts 5, a first part 41, and a second part 42. The sign of the band-like portion is indicated by adding “5” or “5” with a subscript.
図１において、前記少なくとも３本のバンド状部５は前記複数本のスリット７により前記前後方向Ｘに互いに分断されている。前記第１部４１は前記３本のバンド状部５の下方において前記ソール２に沿って前記前後方向Ｘに延び前記３本のバンド状部５に継目なく一体に連なる。前記第２部４２は前記３本のバンド状部５の上方において前記係合部３に沿って前記前後方向Ｘに延び前記３本のバンド状部５に継目なく一体に連なる。 In FIG. 1, the at least three band-like portions 5 are separated from each other in the front-rear direction X by the plurality of slits 7. The first part 41 extends in the front-rear direction X along the sole 2 below the three band-like parts 5 and is continuously connected to the three band-like parts 5 seamlessly. The second portion 42 extends in the front-rear direction X along the engagement portion 3 above the three band-like portions 5 and is continuously connected to the three band-like portions 5 without a joint.
この外皮４の織布の構造を図３および図４を用いて詳細に説明する。 The structure of the woven fabric of the outer skin 4 will be described in detail with reference to FIGS.
図４において、前記複数のバンド状部５は前記係合部３と前記ソール２（図１）との間において斜め上下方向に延び、前縁５ｆおよび後縁５ｂを有する。前記複数のバンド状部５は互いに隣り合う爪先側のバンド状部５ｉと踵側のバンド状部５ｉ＋１とを包含する。前記爪先側のバンド状部５ｉの前記後縁５ｂと、前記踵側のバンド状部５ｉ＋１の前記前縁５ｆとは前記両バンド状部の間においてスリット７を規定する。 In FIG. 4, the plurality of band-shaped portions 5 extend obliquely in the vertical direction between the engaging portion 3 and the sole 2 (FIG. 1), and have a front edge 5f and a rear edge 5b. The plurality of band-like parts 5 include a band-like part 5 i on the toe side and a band-like part 5 i + 1 on the heel side that are adjacent to each other. And the trailing edge 5b of the band-shaped portion 5 i of the toe-side, and the front edge 5f of the band-shaped portion 5 i + 1 of the heel-side to define a slit 7 between the two band-section.
第１部４１はソール２（図１）側において前記互いに隣り合うバンド状部５ｉ，５ｉ＋１の各々に継目なく一体に連なる。第２部４２は前記係合部３側において前記互いに隣り合うバンド状部５ｉ，５ｉ＋１の各々に継目なく一体に連なる。すなわち、前記外皮４の織布Ｔは前記第１部４１から前記爪先側のバンド状部５ｉ、前記第２部４２および前記踵側のバンド状部５ｉ＋１を介して前記第１部４１まで継目なく連なるループを形成している。 The first portion 41 is continuously connected to each of the band-like portions 5 i and 5 i + 1 adjacent to each other on the sole 2 (FIG. 1) side. The second part 42 is continuously connected to each of the adjacent band-like parts 5 i and 5 i + 1 on the engaging part 3 side. That is, the woven fabric T of the outer skin 4 extends from the first part 41 to the first part 41 through the band-like part 5 i on the toe side, the second part 42 and the band-like part 5 i + 1 on the heel side. It forms a continuous loop.
前記各バンド状部５の前記スリット７を規定する前後の縁５ｆ，５ｂにおいて、図６Ｂの織布の繊維Ｆ同士が、図６Ａのように、溶着構造Ｗｃにより互いに固定されている。 At the front and rear edges 5f and 5b that define the slit 7 of each band-like portion 5, the fibers F of the woven fabric of FIG. 6B are fixed to each other by a welding structure Wc as shown in FIG. 6A.
図６Ｂの前記織布Ｔが機械的なカッタで切断されて、前記スリット７（図１）が生成された場合、図６Ｂのように、繊維Ｆ同士がバラけた構造になり易い。 When the woven fabric T in FIG. 6B is cut with a mechanical cutter and the slit 7 (FIG. 1) is generated, a structure in which the fibers F are separated as shown in FIG. 6B is likely to occur.
本例の場合、図６Ａの溶着構造Ｗｃは、前記織布Ｔが例えばレーザービームのような熱溶断機で切断されて、前記スリット７（図１）が生成されている。この場合、織布Ｔの熱可塑性の樹脂繊維が溶けて冷える際に、樹脂留りのようになって、前記溶着構造Ｗｃが生成される。 In the case of this example, in the welding structure Wc of FIG. 6A, the woven fabric T is cut by a thermal fusing machine such as a laser beam to generate the slit 7 (FIG. 1). In this case, when the thermoplastic resin fibers of the woven fabric T are melted and cooled, the weld structure Wc is generated like a resin stay.
図６Ｂのように、織布Ｔは第１の織糸Ｔ１群と第２の織糸Ｔ２群とが互いに織られた織構造を有する。
第１の織糸Ｔ１は図１の前記スリット７の延びる第１方向Ｄ１に沿って延びている。第２の織糸Ｔ２は第１方向Ｄ１に交差する第２方向Ｄ２に沿って延びている。前記織糸Ｔ１群と織糸Ｔ２群とが織構造を構成する。 As shown in FIG. 6B, the woven fabric T has a woven structure in which a first woven yarn T1 group and a second woven yarn T2 group are woven together.
The first woven yarn T1 extends along a first direction D1 in which the slit 7 in FIG. 1 extends. The second woven yarn T2 extends along a second direction D2 that intersects the first direction D1. The woven yarn T1 group and the woven yarn T2 group constitute a woven structure.
第１および第２織糸Ｔ１，Ｔ２が延びる第１および第２方向Ｄ１，Ｄ２に沿った外力が織布Ｔに負荷される場合、織糸Ｔ１，Ｔ２の抗力で織布Ｔは伸び難い。一方、前記方向Ｄ１，Ｄ２に対し斜めのバイヤス方向に外力が負荷される場合、織布Ｔは歪み易い。
したがって、上述のように、スリット７の延びる第１方向Ｄ１に沿って織糸Ｔ１が延びている場合、各バンド状部５は足をホールドする機能を発揮し易い。 When an external force along the first and second directions D1 and D2 in which the first and second woven yarns T1 and T2 extend is applied to the woven fabric T, the woven fabric T hardly stretches due to the drag of the woven yarns T1 and T2. On the other hand, when an external force is applied in a bias direction oblique to the directions D1 and D2, the woven fabric T is easily distorted.
Therefore, as described above, when the woven yarn T1 extends along the first direction D1 in which the slit 7 extends, each band-shaped portion 5 easily exhibits a function of holding the foot.
内皮８を形成するメッシュ状の生地や編物に比べ外皮４を形成する織布（布帛）Ｔは本質的に伸び難く、本例の場合、バンド状部の延びる第１方向Ｄ１については特に伸びにくい。 The woven fabric (fabric) T that forms the outer skin 4 is essentially less stretchable than the mesh-like fabric or knitted fabric that forms the inner skin 8, and in this example, it is particularly difficult to stretch in the first direction D1 in which the band-shaped portion extends. .
バンド状部５は足の最大主曲率方向およびこれに近似した方向に延びていてもよい。この場合、紐締め張力の伝達効率が高まり、ホールド感の調節が容易であろう。
スリット７やバンド状部５の好ましい構造は、図１１および図１２の実施例において説明する。例えば、スリット７は、上下方向に途切れていてもよいし、前後方向に対して角αが異なっていてもよい。 The band-like portion 5 may extend in the direction of the maximum principal curvature of the foot and a direction approximate thereto. In this case, the transmission efficiency of the string tightening tension is increased, and the hold feeling may be easily adjusted.
A preferred structure of the slit 7 and the band-like portion 5 will be described in the embodiments of FIGS. For example, the slit 7 may be interrupted in the up-down direction, or the angle α may be different from the front-rear direction.
図４に示すように、前記外皮４は前記織布Ｔに積層される一対の樹脂フィルムＬ，Ｌを有していてもよい。図３に示すように、本例の場合、一対の樹脂フィルムＬ，Ｌは織布Ｔの一部に織布Ｔの表裏において積層されてもよい。 As shown in FIG. 4, the outer skin 4 may have a pair of resin films L and L laminated on the woven fabric T. As shown in FIG. 3, in the case of this example, the pair of resin films L and L may be laminated on a part of the woven fabric T on the front and back of the woven fabric T.
図４に示すように、各樹脂フィルムＬは第１，第２および第３シート部Ｌ１，Ｌ２，Ｌ３を有し、枠状に構成されていてもよい。樹脂フィルムＬの枠内にはスリット７およびバンド状部５が配置されている。この場合、足のホールド機能を損なうことなく、バンド状部５の変形の自由度が阻害されにくいだろう。 As shown in FIG. 4, each resin film L has 1st, 2nd and 3rd sheet | seat part L1, L2, L3, and may be comprised by frame shape. In the frame of the resin film L, the slit 7 and the band-shaped part 5 are arranged. In this case, the degree of freedom of deformation of the band-like portion 5 will not be hindered without impairing the foot hold function.
図３および図４の第１シート部Ｌ１は前記第１部４１の一部または全部をラミネート（被覆の一例）している。第２シート部Ｌ２は前記第２部４２の一部または全部をラミネート（被覆の一例）している。 The first sheet portion L1 of FIGS. 3 and 4 is laminated (an example of coating) part or all of the first portion 41. The second sheet portion L2 is laminated (an example of coating) part or all of the second portion 42.
図４の前記外皮４は前記係合部３を補強する補強材６を有していてもよい。前記補強材６は樹脂フィルムＬと共に前記第２部４２の一部をラミネートしている。
なお、図５の係合部３にはハトメ具３０が装着されていてもよい。 The outer skin 4 of FIG. 4 may have a reinforcing member 6 that reinforces the engaging portion 3. The reinforcing material 6 is laminated with a part of the second portion 42 together with the resin film L.
Note that an eyelet tool 30 may be attached to the engaging portion 3 of FIG.
図５において、内皮８は前記外皮４およびスリット７を内から覆い足の表面に接するように構成されている。前記内皮８と前記外皮４のバンド状部５とは互いに非接着である。そのため、外皮４が内皮８に対し、自由に変形し得る。 In FIG. 5, the inner skin 8 is configured to cover the outer skin 4 and the slit 7 from the inside and to contact the surface of the foot. The inner skin 8 and the band-like portion 5 of the outer skin 4 are not adhered to each other. Therefore, the outer skin 4 can be freely deformed with respect to the inner skin 8.
図１のスリット７の形状は、図１および図２の比較から分かるように、着用者の足のフェイズに応じて変化する。そのため、歩行や走行時にスリット７を通して視認される内皮８の部位や大きさが変化し、独特の美観が得られる。 The shape of the slit 7 in FIG. 1 changes according to the phase of the wearer's foot, as can be seen from the comparison between FIG. 1 and FIG. Therefore, the site | part and magnitude | size of the endothelium 8 visually recognized through the slit 7 at the time of a walk or a run change, and unique aesthetics are obtained.
図７および図８Ａは実施例２の外皮の構造を示す。
本例において、図７（ａ）～（ｃ）の前記外皮４は織布（布帛）Ｔと樹脂フィルムＬとの積層構造を有する。図８Ａの前記織布Ｔは第１および第２の織糸Ｔ１，Ｔ２が織られている。各織糸Ｔ１，Ｔ２はそれぞれ、複数本の繊維Ｆを含む。 7 and 8A show the structure of the outer skin of Example 2. FIG.
In this example, the outer skin 4 of FIGS. 7A to 7C has a laminated structure of a woven fabric (fabric) T and a resin film L. The woven fabric T in FIG. 8A is woven with first and second woven yarns T1 and T2. Each of the woven yarns T1 and T2 includes a plurality of fibers F.
図７の前記各バンド状部５は前記スリット７を規定する前後の縁５ｆ，５ｂを有する。前記各縁５ｆ，５ｂにおいて、図８Ａの多数の繊維Ｆの一部が前記フィルムＬに溶着構造Ｗｃにより固定されている。すなわち、前記繊維Ｆと前記樹脂フィルムＬとが溶着構造Ｗｃにより互いに固定されている。この溶着構造Ｗｃは、例えばホットメルト（熱可塑性樹脂）で形成された樹脂フィルムＬを織布Ｔに加圧および加熱して貼り付けることにより得られる。 Each band-like portion 5 in FIG. 7 has front and rear edges 5 f and 5 b that define the slit 7. At each of the edges 5f and 5b, some of the large number of fibers F in FIG. 8A are fixed to the film L with a welding structure Wc. That is, the fiber F and the resin film L are fixed to each other by the welding structure Wc. This welded structure Wc is obtained, for example, by applying a resin film L formed of hot melt (thermoplastic resin) to the woven fabric T under pressure and heating.
かかる溶着構造Ｗｃは、例えば、以下のようにして得られる。 Such a welded structure Wc is obtained, for example, as follows.
図７（ａ）および（ｃ）に示すように、互いに積層（溶着）された織布Ｔと樹脂フィルムＬには、互いに合致する同形および同大のスリット７が機械的なカッターにより切断されて形成されている。図８Ａの前記切断された前後の縁５ｆ（５ｂ）の端面において、織布Ｔの多数の繊維の一部は樹脂フィルムＬに溶着されている。これにより、織布Ｔの第１および第２の織糸Ｔ１，Ｔ２が前記フィルムＬに溶着されて、図８Ｂに示すように、繊維Ｆがバラけることが抑制される。 As shown in FIGS. 7A and 7C, the slits 7 having the same shape and the same size are cut by a mechanical cutter in the woven fabric T and the resin film L that are laminated (welded) to each other. Is formed. A part of a large number of fibers of the woven fabric T is welded to the resin film L at the end surfaces of the cut front and rear edges 5f (5b) in FIG. As a result, the first and second woven yarns T1 and T2 of the woven fabric T are welded to the film L, and the fibers F are prevented from being scattered as shown in FIG. 8B.
したがって、図８Ａの溶着構造Ｗｃを有する外皮４は、スリット７（図７）による強度の低下や外観の劣化が抑制されるだろう。 Therefore, the outer skin 4 having the welded structure Wc of FIG. 8A will suppress a decrease in strength and a deterioration in appearance due to the slit 7 (FIG. 7).
図９および図１０は実施例３を示す。
本例の場合、左足用の靴の外足側を示しているが、内足側も同様の構造である。 9 and 10 show a third embodiment.
In this example, the outer foot side of the shoe for the left foot is shown, but the inner foot side has the same structure.
図１０に示すように、本例の場合、アッパー１は前記外皮４を２枚包含する。前記２枚の外皮４が内足および外足の双方の側面において互いに重なっている。 As shown in FIG. 10, in the case of this example, the upper 1 includes two outer skins 4. The two outer skins 4 overlap each other on both sides of the inner foot and the outer foot.
２枚の外皮４の各々は、スリット７および図９のバンド状部５，５を有する。前記２枚の外皮４の前記バンド状部５，５同士が内足または外足の少なくとも一方の側面において互いに交差するように一部において重なっている。
したがって、各外皮４に形成された各スリット７は互いに一部において交差するように重なっており、このスリット７の重なり部分から内皮８の一部が視認される。 Each of the two outer skins 4 has a slit 7 and band- like portions 5 and 5 of FIG. The band- like portions 5 and 5 of the two outer skins 4 partially overlap each other on at least one side surface of the inner foot or the outer foot.
Accordingly, the slits 7 formed in the outer skins 4 overlap each other so as to partially intersect each other, and a part of the inner skin 8 is visually recognized from the overlapping part of the slits 7.
本例の場合、前記第１シート部Ｌ１は前記バンド状部５の下端部５５を覆うと共に前記スリット７の下端部７５を埋める。前記第２シート部Ｌ２は前記バンド状部５の上端部５０を覆うと共に前記スリット７の上端部７０を埋める。 In the case of this example, the first sheet portion L1 covers the lower end portion 55 of the band-like portion 5 and fills the lower end portion 75 of the slit 7. The second sheet portion L2 covers the upper end portion 50 of the band-shaped portion 5 and fills the upper end portion 70 of the slit 7.
図１１～図１３は実施例４を示す。
図１２に示すように、本例の場合、前記複数のバンド状部５のうち、前後方向Ｘに互いに隣り合うバンド状部５ｉ，５ｉ+１の間には２本以上のスリット７，７が設けられている。 11 to 13 show a fourth embodiment.
As shown in FIG. 12, in the case of this example, among the plurality of band-like parts 5, two or more slits 7, between the band-like parts 5 i and 5 i + 1 adjacent to each other in the front-rear direction X, 7 is provided.
図１２において、前記２本以上のスリット７，７は前記スリット７，７の延びる第１方向Ｄ１に互いに離間して配置されている。前記互いに隣り合うバンド状部５ｉ，５ｉ+１は前記第１部４１と前記第２部４２との間の第３部４３において前後方向Ｘに互いに連なっている。 In FIG. 12, the two or more slits 7, 7 are spaced apart from each other in a first direction D <b> 1 in which the slits 7, 7 extend. The adjacent band-like parts 5 i and 5 i + 1 are connected to each other in the front-rear direction X in a third part 43 between the first part 41 and the second part 42.
なお、第１方向Ｄ１に互いに離間したスリット７は３本以上設けられてもよい。スリット７が２本以上設けられている場合、スリット７は千鳥状に配置されてもよい。 Three or more slits 7 spaced apart from each other in the first direction D1 may be provided. When two or more slits 7 are provided, the slits 7 may be arranged in a staggered manner.
各実施例において、図１２に明示するように、前記バンド状部５の幅５ｗの平均値は前記スリット７の幅７ｗの平均値よりも大きい。
バンド状部５の幅５ｗの平均値はスリット７の幅７ｗの平均値の２倍以上が好ましく、３倍以上が更に好ましい。スリット７の幅の平均値が「０」又は「０」に近い場合、前記倍率は無限大または無限大に近い値となるであろう。 In each embodiment, as clearly shown in FIG. 12, the average value of the width 5 w of the band-like portion 5 is larger than the average value of the width 7 w of the slit 7.
The average value of the width 5w of the band-like portion 5 is preferably at least twice the average value of the width 7w of the slit 7, and more preferably at least three times. When the average value of the width of the slits 7 is “0” or close to “0”, the magnification will be infinite or close to infinity.
バンド状部やスリットの幅の平均値とは、例えば、図１２の例のように、バンド状部５が下方に向かって末広がりである場合、バンド状部５の上端の幅と下端の幅との単純平均により、前記バンド状部の幅の平均値に近似した値を算出することができるだろう。かかる場合、足の部位に応じた曲率やアッパーの変形量に対し、バンド状部の幅を適切な値に設定でき、皺の発生を抑制し易いかもしれない。 The average value of the width of the band-shaped part or the slit is, for example, when the band-shaped part 5 is diverging downward as shown in the example of FIG. A value that approximates the average value of the width of the band-like portion can be calculated by a simple average of. In such a case, the width of the band-shaped portion can be set to an appropriate value with respect to the curvature corresponding to the foot region and the amount of deformation of the upper, and it may be easy to suppress the occurrence of wrinkles.
また、図１２の前足部のように、Ｄ１方向に１列に並ぶ複数のスリット７が設けられている場合、複数のスリット７の幅７ｗの平均値ＡＬは下記の（１）式で算出することができるだろう。バンド状部の幅を適切な値に設定でき、皺の発生を抑制し易いかもしれない。
ＡＬ＝（７ｗ１＊７ｌ１＋７ｗ２＊７ｌ２）／（７ｌ１＋７ｌ２）…（１） Further, as the forefoot 12, when a plurality of slits 7 that are arranged in a line in the D1 direction is provided, calculates an average value A L of the width 7w of the plurality of slits 7 (1) below Would be able to. The width of the band-shaped portion can be set to an appropriate value, and it may be easy to suppress wrinkles.
A L = (7w 1 * 7l 1 + 7w 2 * 7l 2 ) / (7l 1 + 7l 2 ) (1)
また、図１２の中足部のように、Ｄ１方向に１列に並ぶ複数のスリット７、７が末広がりである場合、複数のスリット７の幅７ｗの平均値ＡＬは、前述の幅５ｗ，７ｗと同様の方法で求めることができるだろう。 Further, as the midfoot of FIG. 12, when a plurality of slits 7, 7 that are arranged in a line in the D1 direction is divergent, the average value A L of the width 7w of the plurality of slits 7, the aforementioned width 5w, It can be obtained in the same way as 7w.
各実施例において、図３（ｂ）の前記スリット７の長さ７ｌは前記スリット７の幅７ｗの２倍以上である。好ましくは、スリット７の長さ７ｌはスリット７の幅７ｗの３倍以上、より好ましくは４倍以上、最も好ましくは５倍以上に設定される。スリット７の幅の平均値が「０」又は「０」に近い場合、前記倍率は無限大または無限大に近い値となるであろう。なお、スリットの幅７ｗは靴を着用していない状態で、かつ、複数のバンド状部をＤ１方向に引き延ばして測定されるべきである。 In each embodiment, the length 7 l of the slit 7 in FIG. 3B is twice or more the width 7 w of the slit 7. Preferably, the length 7 l of the slit 7 is set to 3 times or more, more preferably 4 times or more, most preferably 5 times or more of the width 7 w of the slit 7. When the average value of the width of the slits 7 is “0” or close to “0”, the magnification will be infinite or close to infinity. The slit width 7w should be measured in a state where no shoes are worn and a plurality of band-like portions are stretched in the D1 direction.
図１２のように、Ｄ１方向に並ぶスリット７が複数本である場合、スリット７の長さ７ｌ（図３）は、複数本のスリット７の長さ７ｉを加算して算出することができる。例えば、スリット７が２本ないしｍ本設けられている場合、スリットの長さ７ｌ（図３）は下記の（２）式ないし（３）式で求めることができる。
７ｌ＝７ｌ１＋７ｌ２…（２）
７ｌ＝７ｌ１＋…＋７ｌｉ＋…７ｌｍ…（３） As shown in FIG. 12, when there are a plurality of slits 7 arranged in the direction D1, the length 7l (FIG. 3) of the slits 7 can be calculated by adding the lengths 7i of the plurality of slits 7. For example, when two to m slits 7 are provided, the slit length 7l (FIG. 3) can be obtained by the following equations (2) to (3).
7l = 7l 1 + 7l 2 (2)
7l = 7l 1 + ... + 7l i + ... 7l m ... (3)
各実施例において、図３の前記スリットの長さ７ｌは前記バンド状部５の幅５ｗの平均値の２倍以上で、好ましくはバンド状部５の幅５ｗの平均値の３倍以上、より好ましくは４倍以上、最も好ましくは５倍以上に設定される。この倍率も前述と同様に無限大または無限大に近い値となり得る。 In each embodiment, the slit length 7l in FIG. 3 is at least twice the average value of the width 5w of the band-like portion 5, preferably at least three times the average value of the width 5w of the band-like portion 5. Preferably it is set to 4 times or more, and most preferably 5 times or more. This magnification can also be infinite or close to infinity as described above.
ここで、スリット７の長さ７ｌは、バンド状部５の長さを定義付ける。すなわち、バンド状部５の前後のスリット７の長さ７ｌの平均値がバンド状部５の長さと考えることができる。したがって、バンド状部５の幅５ｗの平均値に対し、前述のようなスリットの長さ７ｌを有する場合、第１方向Ｄ１に長いバンド状部５を実現できる。
このように、第１方向Ｄ１に長いバンド状部５は、シューレースの締付力により足に沿い易く、安定性能を発揮するだろう。 Here, the length 7 l of the slit 7 defines the length of the band-shaped portion 5. That is, the average value of the lengths 7 l of the slits 7 before and after the band-like part 5 can be considered as the length of the band-like part 5. Therefore, when the slit length 7l as described above is provided with respect to the average value of the width 5w of the band-shaped portion 5, the long band-shaped portion 5 in the first direction D1 can be realized.
As described above, the band-shaped portion 5 that is long in the first direction D1 is likely to follow the foot due to the tightening force of the shoelace, and will exhibit stable performance.
このようなことから、図３（ｂ）の多数のスリット７のうち少なくとも互いに第２方向Ｄ２に隣り合うスリット７の長さ７ｌ（１つのバンド状部の長さ）は、１０ｍｍ以上が好ましく、１５ｍｍ以上が更に好ましく、２０ｍｍが最も好ましい。このスリット７の長さ７ｌは、図１２のスリット７が第１方向Ｄ１に複数本設けられている場合、各スリットの長さ７ｌ１，７ｌ２の合計値である。
なお、スリットの長さの上限値は、足の長さにもよるが一般に１００ｍｍ以下であろう。 Therefore, the length 7l (the length of one band-shaped portion) of at least the slits 7 adjacent to each other in the second direction D2 among the multiple slits 7 in FIG. 3B is preferably 10 mm or more. 15 mm or more is more preferable, and 20 mm is most preferable. The length 7l of the slit 7, if the slit 7 in FIG. 12 are provided a plurality of the first direction D1, a length 7l 1, the total value of 7l 2 of each slit.
The upper limit of the slit length will generally be 100 mm or less, although it depends on the length of the foot.
図３ｂにおいて、各バンド状部５の幅５ｗが小さい場合、多数のバンド状部５のうち、特定の１本のバンド状部５に負荷が生じたり、あるいは、バンド状部５が異物に引っ掛かるおそれがある。
このようなことから、前記スリット７の長さ７ｌはバンド状部５の幅５ｗの平均値の１００倍以下が好ましく、５０倍以下が更に好ましく、２０倍以下が最も好ましい。 In FIG. 3b, when the width 5w of each band-like part 5 is small, a load is generated in one specific band-like part 5 among the many band-like parts 5, or the band-like part 5 is caught by a foreign object. There is a fear.
For this reason, the length 7l of the slit 7 is preferably 100 times or less, more preferably 50 times or less, and most preferably 20 times or less the average value of the width 5w of the band-like portion 5.
このようなことから、図１の多数（３本以上）のバンド状部５１～５ｎのうち、図３の少なくとも３本のバンド状部５の幅５ｗは、３ｍｍ以上が好ましく、４ｍｍ以上がより好ましく、５ｍｍ以上が更に好ましく、６ｍｍ以上が最も好ましい。
なお、バンド状部５の幅５ｗの上限値は、係合部３の配置範囲との関係上、一般に、４０ｍｍ以下が好ましく、３０ｍｍ以下がより好ましく、２０ｍｍ以下が更に好ましく、１５ｍｍ以下が最も好ましい。 Therefore, among the large number (three or more) of band-like portions 5 1 to 5 n in FIG. 1 , the width 5w of at least three band-like portions 5 in FIG. 3 is preferably 3 mm or more, and 4 mm or more. Is more preferably 5 mm or more, and most preferably 6 mm or more.
The upper limit value of the width 5w of the band-shaped part 5 is generally preferably 40 mm or less, more preferably 30 mm or less, still more preferably 20 mm or less, and most preferably 15 mm or less, in relation to the arrangement range of the engaging part 3. .
各実施例において、図１１のように、前記スリット７と前記ソール２の接地面２２とのなす角αは４５°～９０°である。 In each embodiment, as shown in FIG. 11, the angle α formed by the slit 7 and the ground contact surface 22 of the sole 2 is 45 ° to 90 °.
すなわち、接地面２２に対するスリット７の延びる方向Ｄ１の傾斜は、前方の下方に向かう傾斜であってもよいし、逆に、後方の下方に向かう傾斜であってもよい。また、第１方向Ｄ１が接地面に直交するようにスリット７が設けられていてもよい。 That is, the inclination in the direction D1 in which the slit 7 extends with respect to the ground plane 22 may be an inclination toward the front lower side, or conversely, an inclination toward the lower rear side. Further, the slit 7 may be provided so that the first direction D1 is orthogonal to the ground plane.
なお、多数のスリット７のうち、一部のスリット７について、前記角αが４５°以下であってもよい。少なくとも２本のバンド状部５を定義する３本のスリット７について、前記角αが４５°～９０°であればよい。 In addition, about some slits 7 among many slits 7, the said angle (alpha) may be 45 degrees or less. For the three slits 7 defining at least two band-like portions 5, the angle α may be 45 ° to 90 °.
以上のとおり、図面を参照しながら好適な実施例を説明したが、当業者であれば本明細書を見て、自明な範囲で種々の変更および修正を容易に想定するであろう。
アッパーの下に配置されるソールは、いわゆるアウトソールのみを有していてもよい。
バンド状部５およびスリット７は内足または外足の一方または双方に設けられてもよい。また、内皮やホットメルトシートは設けられていなくてもよい。
シューレースが通る係合部は鳩目ではなく、ループ等であってもよい。
シューレースに代え、あるいは、シューレースに加えて、締付部材としてベルトが採用されてもよい。
また、外皮を形成する布帛は織布の他に不織布などのアッパー材を用いてもよい。
