Description

本発明は、紳士靴や運動靴等の各種靴用の靴底（本底）と、その本底を取付けた靴に関する。 The present invention relates to a sole (outsole) for various shoes such as men's shoes and athletic shoes, and a shoe to which the outsole is attached.

紳士靴や婦人靴、運動靴等の本底には各種形状、構造のものがある。靴の製造方法も各種あり、グッドイヤーウェルト製法、マッケイ製法、ステッチダウン製法、セメンテッド製法等々がある。 There are various shapes and structures on the bottom of men's shoes, women's shoes, and athletic shoes. There are various shoe manufacturing methods, such as the Goodyear Welt manufacturing method, the Mackay manufacturing method, the stitch-down manufacturing method, the cemented manufacturing method, and the like.

グッドイヤーウェルト製法は、アッパー（製甲）と細革を中底リブにすくい縫いし、中底リブの内側に中物、シャンクを詰め、中物、シャンクの外（上）から中底に本底を重ね、その本底と前記細革を出し縫い糸で出し縫いし、その本底に踵パーツを接着し、出し縫い部分よりも外側に出っ張っている本底及び踵パーツの出っ張り部分（コバ）を回転刃物で切削除去し、その後に、バフや紙ヤスリ等の研磨具で研磨する。 The Goodyear welt manufacturing method scoops the upper (armor) and fine leather to the insole rib, stuffs the inside and shank inside the insole rib, and fills the bottom from the outside of the inside and shank (top) to the insole Lay out the bottom and the above-mentioned leather and sew out with the sewing thread, glue the heel part to the bottom, and the protruding part (edge) of the outsole and the heel part protruding outward from the sewed part. It is removed by cutting with a rotary blade, and then polished with a polishing tool such as a buff or a paper file.

マッケイ製法は、つり込み済みの製甲と中底に、本底を張り付けて、靴型を抜いてから、製甲と中底と本底の三者を一緒に縫い糸で通し縫いをする。この場合も、コバの切削除去、研磨を行う。 In the McKay method, the bottom is attached to the suspended shell and the insole, the shoe mold is pulled out, and then the former, the insole and the bottom are stitched together with sewing threads. Also in this case, the edge is cut off and polished.

ステッチダウン製法は、甲革を外側に向けてつり込み、表皮を張り付け、その上に細革をのせ、甲革と細革と本底を、出し縫い糸で縫う製法である。この場合も、コバの切削除去、研磨を行う。 The stitch-down manufacturing method is a manufacturing method in which the upper is faced outward, the skin is attached, the fine leather is placed on it, and the upper, the fine leather, and the bottom of the upper are sewn with the sewing thread. Also in this case, the edge is cut off and polished.

出し縫いするグッドイヤーウェルト製法やステッチダウン製法、通し縫いするマッケイ製法のように、本底を糸で縫い付ける製法では、糸の締め付けにより本底に亀裂が入らず、本底が裂けない強度が本底に要求される。 Like the Goodyear welt manufacturing method, stitch-down manufacturing method, and Mackay manufacturing method, which sew through stitches, the manufacturing method in which the bottom is sewn with a thread does not crack the bottom of the bottom due to the tightening of the thread, and the strength that does not tear the bottom Required at the bottom.

グッドイヤーウェルト製法、ステッチダウン製法、マッケイ製法のように本底の踵部分及び踵パーツのコバを切削し、その後に研磨する製法では、研磨部分が研磨時の発熱で軟化すると、研磨カスがバフや紙ヤスリに付着して、バフや紙ヤスリ等が目詰まりして、研磨効率が低下したり、研磨した本底の踵部分及び踵パーツが研磨カスで汚れたりすることがある。このため、本底の踵部分及び踵パーツには研磨時に溶融し難い（しない）耐熱性が要求される。発熱温度は本底の踵部分、踵パーツの素材（材質）によっても異なるが、一般的には８０℃程度であるため、本発明で要求される耐熱温度は少なくともその温度以上が望ましい。 In the manufacturing method in which the edge part of the bottom base and the edge of the heel part are cut and then polished like the Goodyear welt manufacturing method, stitch-down manufacturing method, and McKay manufacturing method, if the polishing part softens due to the heat generated during polishing, It may adhere to the paper file and clog the buff, paper file, etc., and the polishing efficiency may decrease, or the polished bottom heel portion and heel parts may become dirty with the polishing residue. For this reason, the heel portion and the heel part of the bottom are required to have heat resistance that is difficult to melt during polishing. The exothermic temperature varies depending on the heel part of the bottom and the material (material) of the heel part, but is generally about 80 ° C., and therefore, the heat-resistant temperature required in the present invention is preferably at least the temperature.

近年、靴には、軽量性、耐摩耗性、屈曲性、柔軟性、通気性、防水性、緩衝機能等の各種性能や機能に優れていること、生産性向上やコストダウン等の面から製造容易であること等が要求されている。これら要求を実現すべく靴も本底も種々改善されている。本底には革製、ゴム製、樹脂製といった各種材質製のものがある。従来の本底は樹脂、革といった一種類の材料で成形された一枚物が一般的であったが、近年は、各種材質製の部品（本底パーツ）を組合せて一枚にしたもの（複合本底）が開発されている（特許文献1〜７）。 In recent years, shoes have been manufactured from the standpoints of superior performance and functions such as lightness, wear resistance, flexibility, flexibility, breathability, waterproofness, shock absorbing function, productivity improvement and cost reduction. It must be easy. Various shoes and bottoms have been improved to meet these requirements. There are various materials such as leather, rubber, and resin on the bottom. Conventional single-sole products are usually made of one kind of material such as resin or leather, but in recent years, parts made of various materials (outsole parts) are combined into one piece ( Composite bottoms) have been developed (Patent Documents 1 to 7).

本発明の靴底及び靴は次の効果がある。
（１）全面パーツ及び後パーツに耐締め付け強度があるため、縫い糸で強く締付けても全面パーツ及び後パーツが裂けたり亀裂が入ったりし難くなる。
（２）全面パーツ及び後パーツがコバ研磨時の発熱で溶融しにくい耐熱性を備えた材質製であるため、研磨具に研磨カスが付着して研磨具が目詰まりし難くなり、研磨効率が低下し難く、コバを汚さず綺麗に研磨することができる。
（３）内パーツと外片が成型により一体化されているので、両者の接合が強固で剥離し難くなる。
（４）全面パーツをその嵌合口を内パーツの突出部に被せて外片に重合接着したので、全面パーツが所定位置に重合接着され、接着後に位置ずれしにくい。
（５）前パーツと後パーツに分かれているため、前パーツは本底の前方部分に必要な機能や性能を備えた材質、構成とし、後パーツは本底の後方部分に必要な機能や性能を備えた材質、構成とすることができ、全体が一枚物である本底よりも、本底に必要な機能、特性を備えた本底とすることができる。

（７）内パーツが耐滑性を備えている場合は、歩行時に滑りにくくなる。
（８）内パーツが軟質材製或いは弾性材製の場合は、歩行時に屈曲し易く衝撃が吸収されるので、足に優しいものとなる。また、加工もし易い。さらに、厚くしても屈曲性、弾性が確保され易いので、歩行し易い範囲で厚くした場合はより一層衝撃緩和に役立つ。 The shoe sole and shoes of the present invention have the following effects.
(1) Since the entire surface part and the rear part have a clamping strength, the entire surface part and the rear part are not easily torn or cracked even if tightened with a sewing thread.
(2) Since the entire surface parts and rear parts are made of a material with heat resistance that is difficult to melt due to the heat generated during edge polishing, the polishing debris adheres to the polishing tool, making it difficult for the polishing tool to become clogged and improving the polishing efficiency. It is difficult to decrease and can be polished finely without polluting the edge.
(3) Since the inner part and the outer piece are integrated by molding, the joint between them is strong and difficult to peel off.
(4) Since the entire surface part is overlapped and bonded to the outer piece by covering the fitting port with the protruding portion of the inner part, the entire surface part is overlapped and bonded at a predetermined position, and is not easily displaced after bonding.
(5) Since the front part and the rear part are separated, the front part is made of a material and composition with the functions and performance required for the front part of the bottom, and the rear part is a function and performance required for the rear part of the bottom. The outsole can have a function and characteristics necessary for the outsole rather than the outsole which is a single piece as a whole.
(6) When the inner part has a function that is easy to bend and return, it becomes easy to walk and fatigue is difficult.
(7) When the inner part has slip resistance, it becomes difficult to slip when walking.
(8) When the inner part is made of a soft material or an elastic material, it is easy to bend during walking and absorbs an impact, so that it is gentle to the foot. Moreover, it is easy to process. Furthermore, since flexibility and elasticity are easily ensured even if the thickness is increased, if the thickness is increased within the range where walking is easy, it is further useful for reducing the impact.

（本底の実施形態）
本発明の本底１の一例を図１〜図４を参照して説明する。図１に示す本底１は、図２（ａ）〜（ｃ）に示す前パーツ２と、全面パーツ３と、後パーツ４を備えている。 (Embodiment embodiment)
An example of the bottom 1 of the present invention will be described with reference to FIGS. The bottom 1 shown in FIG. 1 includes a front part 2, a full surface part 3, and a rear part 4 shown in FIGS. 2 (a) to 2 (c).

前パーツ２（図２（ｂ））は、靴の踵側よりも先方側の略中央部（踏み付け部）となる内パーツ５（図１、図２（ｂ））と、その外側の外片６（図１、図２（ｂ））で構成される。外片６は成型により内パーツ５の外側ほぼ全周に突設されている。図４（ａ）、（ｂ）の外片６は内パーツ５よりも肉薄に成型されて、内パーツ５が外片６の内面６ａよりも内側に突出している。 The front part 2 (FIG. 2 (b)) includes an inner part 5 (FIGS. 1 and 2 (b)), which is a substantially central part (stepping part) on the front side of the shoe heel side, and an outer piece on the outer side. 6 (FIGS. 1 and 2B). The outer piece 6 protrudes almost entirely around the outer side of the inner part 5 by molding. The outer piece 6 in FIGS. 4A and 4B is formed thinner than the inner part 5, and the inner part 5 protrudes inward from the inner surface 6 a of the outer piece 6.

内パーツ５は前方部分５ａが先細りのほぼ楕円形であり、後方部分５ｂが細長に形成され、最後尾に方形の突起５ｃが突設されている。内パーツ５の外周縁部５ｄ（図３）は内側を外側よりも一段低くして上下二段にしてある。 The inner part 5 has a substantially elliptical shape with a front portion 5a that is tapered, a rear portion 5b that is elongated, and a square protrusion 5c that protrudes from the rear end. The outer peripheral edge portion 5d (FIG. 3) of the inner part 5 is formed in two upper and lower stages, with the inside being one step lower than the outside.

内パーツ５は屈曲性、耐滑性等を備えた物が好ましい。屈曲性を備えるためには、例えば、内パーツ５の裏面に横溝（横幅方向に長い溝）を設けるとか、内パーツ５の肉厚内に穴を開けて、それら横溝や穴の部分の肉厚を薄くして、それら肉薄部分を歩行時に曲がり易くする（屈曲し易くする）と共に返り易く（戻り易く）することができる。 The inner part 5 is preferably a material having flexibility, slip resistance and the like. In order to provide flexibility, for example, a lateral groove (long groove in the lateral width direction) is provided on the back surface of the inner part 5, or a hole is formed in the thickness of the inner part 5, and the thickness of the lateral groove or hole portion is increased. It is possible to make the thin portion easy to bend (walk easily) and return easily (easy to return) during walking.

耐滑性を備えるためには、例えば、内パーツ５に接地面に向かって突出部等の凹凸を設けることができる。一般的に、乾燥した路面においては、柔らかい底材の方が、耐滑性が向上するため、内パーツ５に硬度が低いものを用いることでより高い耐滑性を実現できる。また、濡れた路面においては、突出部等を備えることで、高い耐滑性を実現することができる。 In order to provide slip resistance, for example, the inner part 5 can be provided with irregularities such as protrusions toward the grounding surface. In general, on a dry road surface, the soft bottom material improves the slip resistance. Therefore, by using the inner part 5 having a low hardness, higher slip resistance can be realized. Further, on a wet road surface, high slip resistance can be realized by providing a protrusion or the like.

内パーツ５を歩行時に屈曲し易く、返り易いものにするためには、異なる素材製の内パーツ５を二枚以上積層することもできる。内パーツ５が単一素材製の一枚物であっても、二層以上の積層構造であっても、内パーツ５は型枠内に樹脂を注入（充填）して外片６と一体に型成形する。積層された内パーツ５の場合は、それら二層以上の内パーツ５ともそれぞれ前記樹脂で一体化（接合或いは接着）する。一体化し易く積層された二枚以上の内パーツ５が一体化し易い樹脂としては、ゴム材等に比して加熱の時間が短時間で済み、他の素材を傷つけずに成型しやすい性質を有しているためＴＰＵ（熱可塑性ポリウレタン）が適する。しかし、ＴＰＵはコバ研磨時の発熱に耐え得る耐熱性と、縫い糸による締付け力に耐え得る耐締付け力が弱い（硬度が低い）。 In order to make the inner part 5 easy to bend and return when walking, two or more inner parts 5 made of different materials can be stacked. Regardless of whether the inner part 5 is a single material or a laminated structure of two or more layers, the inner part 5 is integrated with the outer piece 6 by injecting (filling) resin into the mold. Mold. In the case of the laminated inner parts 5, these two or more inner parts 5 are also integrated (bonded or bonded) with the resin. As a resin that is easy to integrate and two or more inner parts 5 that are easily stacked can be easily integrated, the heating time is shorter than that of rubber, etc., and it is easy to mold without damaging other materials. Therefore, TPU (thermoplastic polyurethane) is suitable. However, TPU has low heat resistance that can withstand the heat generated during edge polishing and low tightening force that can withstand the tightening force of the sewing thread (low hardness).

本発明では前記耐熱性と耐締付け力を確保するために、内パーツ５とは別に一体化全面パーツ３（図２（ａ））を使用する。全面パーツ３（図２（ａ））は踵側と先方側とを一体にした一枚物であり、ほぼ、靴底全体の形状をしており、先方側中央部に嵌合口８が開口されている。嵌合口８は図２（ａ）、図４（ａ）のように、内パーツ５の外周に被せることのできる大きさである。この全面パーツ３は図４（ｂ）のように、外片６の内面６ａの上に重ね合せて接着剤で接着（重合接着）される。全面パーツ３の素材は微発泡性のＥＶＡ（エチレンビニルアセテート）が適する。ＥＶＡは少なくともコバ切削時の発熱温度以上の耐熱性と、靴製造時の縫い糸の締め付けに耐え得る強度（耐締め付け強度：硬度）を備えている。この硬度はＪＩＳ−Ａ硬度６５〜９５のものが望ましい。前記前パーツ２が耐締め付け強度を有する場合の強度も、少なくともこれと同様であることが望ましい。 In the present invention, in order to ensure the heat resistance and the clamping force, an integrated whole surface part 3 (FIG. 2A) is used separately from the inner part 5. The entire surface part 3 (FIG. 2 (a)) is a single piece in which the heel side and the front side are integrated, almost the shape of the sole, and the fitting port 8 is opened at the center of the front side. ing. The fitting port 8 has a size that can be put on the outer periphery of the inner part 5 as shown in FIGS. 2 (a) and 4 (a). As shown in FIG. 4B, the entire surface part 3 is superposed on the inner surface 6a of the outer piece 6 and bonded (polymerized) with an adhesive. The material of the entire surface part 3 is suitably a foaming EVA (ethylene vinyl acetate). EVA has at least heat resistance equal to or higher than the heat generation temperature during edge cutting and strength (fastening strength: hardness) that can withstand the tightening of the sewing thread during shoe manufacture. This hardness is preferably JIS-A hardness 65-95. It is desirable that the strength when the front part 2 has a clamping strength is at least the same as this.

後パーツ４（図２（ｃ））は前方方形、後方円形であり、前縁に開口部９が開口されている。開口部９は内パーツ５の外周に被せることができる大きさである。この後パーツ４は図４（ｂ）のように前パーツ２の上に重合接着された全面パーツ３の踵側底面３ａ（図４（ａ））に重合接着される。後パーツ４の素材は、合成ゴム（天然ゴムと石油系ゴムの合成）が適する。合成ゴムは少なくともコバ切削研磨時の発熱温度以上の耐熱性を備えている。この合成ゴムは靴製造時の縫い糸の締め付けに耐え得る強度（耐締め付け強度：前記硬度）を備えたものであってもよい。この場合は、ダブルの靴を作ることができる。ここでダブルの靴とは靴製造業界用語であり、シングルの靴に対応する。シングルの靴は図５（ａ）のように、本底１の周囲のうち、踵の手前までを出し縫い糸２６で縫い付けた（シングル縫いした）靴であり、ダブルの靴は本底１の周囲全周（踵部分の外周まで）を出し縫い糸２６で縫い付けた（ダブル縫いした）靴である。 The rear part 4 (FIG. 2C) has a front square shape and a rear circular shape, and an opening 9 is opened at the front edge. The opening 9 has a size that can be put on the outer periphery of the inner part 5. Thereafter, the part 4 is polymerized and adhered to the bottom side 3a (FIG. 4 (a)) of the entire surface part 3 which is polymerized and adhered onto the front part 2 as shown in FIG. 4 (b). The material of the rear part 4 is suitable for synthetic rubber (synthesis of natural rubber and petroleum rubber). Synthetic rubber has at least heat resistance equal to or higher than the heat generation temperature during edge cutting and polishing. The synthetic rubber may have a strength (fastening strength: the hardness) that can withstand the tightening of the sewing thread during shoe manufacture. In this case, double shoes can be made. Here, the double shoe is a shoe manufacturing industry term and corresponds to a single shoe. As shown in FIG. 5 (a), the single shoe is a shoe that has been sewn to the front of the heel in the periphery of the bottom 1 and sewed with a sewing thread 26 (single-sewn). This is a shoe that has been taken out around the entire circumference (up to the outer periphery of the heel portion) and sewed with a sewing thread 26 (double-sewn).
