Abstract
Description
本発明は、履物、例えば、ハイヒール、パンプス、サンダルなどの女性用靴、紳士靴、運動靴など多様な履物内部の中底体やその上に装着する中敷体およびそれらを装着した履物に関する。 The present invention relates to footwear, for example, insoles in various footwear such as women's shoes such as high heels, pumps, and sandals, men's shoes, and athletic shoes, and insoles to be mounted thereon, and footwear to which these are attached.
靴の使用において良く指摘される問題の一つに靴の弾力や柔軟性がある。足は歩行の過程で足指や足底の関節を屈曲させながら変化して前後に進んでゆく。そのため、靴があまりに硬いと歩行中に大きなストレスを感じて疲れてしまう。一方、靴全体が柔らかい場合、足の接地から足指や足底の関節の屈曲までがしっかりとサポートされず、不安定感が増してしまい、やはり歩行中に大きなストレスを感じて疲れてしまう。 One of the problems often pointed out in the use of shoes is the elasticity and flexibility of shoes. The foot changes while flexing the toes and plantar joints during the walking process and moves forward and backward. Therefore, if the shoes are too hard, they will feel tired by feeling great stress during walking. On the other hand, if the entire shoe is soft, the contact from the ground of the foot to the flexion of the joints of the toes and soles is not supported firmly, increasing the sense of instability, and also feeling tired by feeling great stress during walking.
従来技術において、歩行をサポートするために足指や足底の関節が屈曲する箇所、特に拇指球から小指球が当接する箇所の屈曲性の向上を図る技術が幾つか知られている。
特許公報１（特開平０９−１４０４０９号公報）に開示された靴は、図４に示すように、比較的硬質素材からなる後側下面材１６、後側上面材１７、前側上面材２１と、硬質素材であるシャンク１８と、軟質素材である中間材２０を備え、後部側で後側下面材１６と後側上面材１７がシャンク１８を介して積層されるとともに、この後側下面材１６と後側上面材１７の先端部に、中間材２０の後端部が局部的にサンドイッチ状に挟み込まれている構造となっている。そして中間材２０の先端側上面には、後側上面材１７の先端から所定間隔離れた位置に前側上面材２１が貼着されている。
In the prior art, several techniques are known for improving the bendability of locations where the toes and sole joints bend to support walking, particularly where the little ball touches the thumb ball.
As shown in FIG. 4, the shoe disclosed in Patent Publication 1 (Japanese Patent Laid-Open No. 09-140409) includes a rear lower surface material 16, a rear upper surface material 17, a front upper surface material 21 made of a relatively hard material, A shank 18 that is a hard material and an intermediate material 20 that is a soft material are provided, and a rear lower surface material 16 and a rear upper surface material 17 are laminated via the shank 18 on the rear side. It has a structure in which the rear end portion of the intermediate member 20 is sandwiched locally in the front end portion of the rear upper surface member 17. A front upper surface material 21 is attached to the upper surface on the front end side of the intermediate material 20 at a position spaced from the front end of the rear upper surface material 17 by a predetermined distance.
このように、特許公報１の技術は複雑な構造をしており、硬度の異なる複数の素材を複雑に組み合わせている。特許公報１では、後側下面材１６と後側上面材１７は、商品名テキソンと呼ばれる硬質ボードであり、また、前側上面材２１はファイバーボードであり、硬度の大きな素材である。中間材２０は不織布などで硬度が比較的小さく、屈曲容易な素材とされている。この結果、前側上面材２１の貼着部と、後側下面材１６、後側上面材１７の積層部は比較的硬質で容易に屈曲しないが、前側上面材２１と後側下面材１６に挟まれる中間材２０の部分は屈曲性があるものとして提供されている。さらに、この屈曲容易な素材の底面の少なくとも一部に、屈曲性を助長する切込加工を施す技術が開示されている。 As described above, the technique disclosed in Patent Publication 1 has a complicated structure, and a plurality of materials having different hardnesses are combined in a complicated manner. In Patent Publication 1, the rear lower surface material 16 and the rear upper surface material 17 are hard boards called trade name texons, and the front upper surface material 21 is a fiber board, which is a material with high hardness. The intermediate material 20 is a non-woven fabric or the like having a relatively small hardness and being easily bent. As a result, the adhesive portion of the front upper surface material 21 and the laminated portion of the rear lower surface material 16 and the rear upper surface material 17 are relatively hard and do not bend easily, but are sandwiched between the front upper surface material 21 and the rear lower surface material 16. A portion of the intermediate member 20 is provided as being flexible. Furthermore, a technique is disclosed in which at least a part of the bottom surface of the easily bent material is subjected to a cutting process that promotes flexibility.
次に、特許文献２（特開２００１−６１５０９号公報）に開示された靴では、図５に示すように、本底の接足面側にインソールボードが配設される靴底の構造において、インソールボードを、爪先部を主体とする先端部１と、踏付け部を主体とする中間部１ｂと、不踏部及び踵部を主体とする基端部１ｃに分割して構成し、先端部と基端部は比較的硬度の高い素材から成形するとともに、中間部はそれより硬度の低い屈曲性のある素材から成形することが開示されている。先端部、中間部、基端部は、それぞれ硬度の異なる別素材で提供されたものを、後工程で組み合わせて接合するものとなっている。
先端部と基端部は、比較的硬度の高い素材であり、合成樹脂板やテキソン（商標名）などの素材で部材が製造され、中間部は、屈曲性のある素材であり、不織布や織布や軟質樹脂等で部材が製造され、それらを接合すると開示されている。なお、先端部と中間部の接合、及び中間部と基端部の接合は、相欠き継により段差が生じないよう接合することが開示されている。
Next, in the shoe disclosed in Patent Document 2 (Japanese Patent Application Laid-Open No. 2001-61509), as shown in FIG. 5, in the structure of the shoe sole in which the insole board is disposed on the foot contact surface side of the sole, The insole board is divided into a distal end portion 1 mainly composed of a toe portion, an intermediate portion 1b mainly composed of a stepping portion, and a proximal end portion 1c mainly composed of a non-stepped portion and a heel portion. It is disclosed that the base end portion is formed from a material having a relatively high hardness, and the intermediate portion is formed from a flexible material having a lower hardness. The tip portion, the intermediate portion, and the base end portion are joined by combining the materials provided by different materials having different hardnesses in a subsequent process.
The tip and the base end are made of a material with relatively high hardness, and the members are made of a material such as a synthetic resin plate or Texon (trade name). It is disclosed that members are made of cloth, soft resin, or the like and joined together. In addition, it is disclosed that the joining of the front end part and the intermediate part and the joining of the intermediate part and the base end part are performed so as not to cause a step due to the joint.
しかし、上記従来の屈曲性を有する中底を備えた靴には以下の問題があった。
第１の問題は、硬度の異なる部材を個別に製造して接合するため、足裏のつま先から踵まで３次元的な立体形状を滑らかに連続して形成することが難しいという問題である。
生身の足裏の表面は滑らかで、完全に一体的な３次元立体形状である。理想的な中底は、その足裏の表面に沿う滑らかで完全に一体的な３次元立体形状を持つ必要がある。
上記した特許文献１の技術によれば、足先２１、拇指球から小指球のラインを含む中間部分２０、後側下面材１６と後側上面材１７が、明らかに断続的に接合されており、足裏の表面に沿う滑らかで完全に一体的な３次元立体形状とはなっていない。中間部分２０を後側下面材１６と後側上面材１７でサンドイッチ構造とするなどの工夫はされているものの、完全に一体的な３次元立体形状とはなっていない。
上記した特許文献２の技術によれば、先端部１と中間部１ｂと基端部１ｃに分割されており、それぞれ硬度の異なる部材として独立に製造された後、後工程で接合されており、構成されており、足裏の表面に沿う滑らかで完全に一体的な３次元立体形状とはなっていない。先端部１と中間部１ｂと基端部１ｃの接合を、相欠き継とする工夫はされているが、相欠き継は両者が、完全な平面で高さに変化がない板体同士の接合に使用される技術で、起伏に富んだ３次元立体形状を個別に製造した後、相欠き継にて完全に一体的に滑らかに接合することは困難である。
However, the conventional shoe having an insole having flexibility has the following problems.
The first problem is that it is difficult to form a three-dimensional solid shape smoothly and continuously from the toes of the soles to the heels because members having different hardnesses are individually manufactured and joined.
The surface of the live sole is smooth and has a completely integrated three-dimensional shape. An ideal insole needs to have a smooth, fully integrated three-dimensional solid shape along the sole surface.
According to the technique of Patent Document 1 described above, the foot 21, the middle portion 20 including the thumb ball to pinky ball line, the rear lower surface material 16 and the rear upper surface material 17 are clearly joined intermittently. The three-dimensional shape is not smooth and completely integrated along the surface of the sole. Although the intermediate portion 20 is devised such as a sandwich structure between the rear lower surface material 16 and the rear upper surface material 17, it is not a completely integrated three-dimensional solid shape.
According to the technique of the above-described Patent Document 2, the tip portion 1, the intermediate portion 1b, and the base end portion 1c are divided and manufactured independently as members having different hardness, and then joined in a subsequent process. It is configured and is not a smooth and completely integrated three-dimensional solid shape along the surface of the sole. Although it has been devised that the joining of the tip portion 1, the intermediate portion 1b and the base end portion 1c is a phase-joint, the phase-joint is a joint between plates that are completely flat and have no change in height. In this technique, it is difficult to produce a three-dimensional shape rich in undulations individually, and then completely and smoothly join them together at a phase-joint.
第２の問題は、製造工程が複雑となり、手間、時間、コストが掛かる点である。
上記した特許文献１の技術によれば、図４を見ても明らかなように、中底部分だけを見ても、足先２１、拇指球から小指球のラインを含む中間部分２０、後側下面材１６と、後側上面材１７と、明らかに部品点数が多く、それらが個別に製造されたものを組立加工所に集約して、組立工程によって、複雑に接合・組み立ててゆく必要があり、足裏の表面に沿う滑らかな立体的形状に仕上げるには相当の手間、時間、コストが掛かる。
上記した特許文献２の技術によれば、図５に明らかなように、中底だけを見ても３点の部品点数があり、それぞれを２か所の相欠き継という技術で接合する必要がある。３点の部品点数は起伏に富んだ３次元立体的形状であるため、相欠き継にて接合するためには、接合面全面にわたって慎重に細かい作業を必要とし、手作業では、接合箇所の段差が生じたり相欠き継の接合強度がバラついたりして、剥離してしまうという不具合が発生することも予想される。
The second problem is that the manufacturing process becomes complicated and takes time, cost and cost.
According to the technique of Patent Document 1 described above, as is apparent from FIG. 4, even when only the midsole portion is seen, the foot 21, the intermediate portion 20 including the line of the little ball to the little ball, the rear side The lower surface material 16 and the rear upper surface material 17 clearly have a large number of parts, and it is necessary to consolidate those manufactured individually into an assembly processing plant and to join and assemble them in an intricate manner by the assembly process. It takes considerable effort, time, and cost to finish a smooth three-dimensional shape along the surface of the sole.
According to the technique of Patent Document 2 described above, as is apparent from FIG. 5, there are three parts even if only the insole is seen, and it is necessary to join each of them with the technique of two-phase succession. is there. The three parts are three-dimensional shapes with many undulations. Therefore, to join at the joints, careful work is required over the entire joint surface. It is also expected that there will be a problem that peeling occurs due to the occurrence of cracks or the joint strength of phase-separated joints.
そこで、本発明は、上記問題に鑑みてなされたものであり、従来技術では不十分であった足裏の表面に沿う滑らかで完全に一体的な３次元立体形状を一工程で機械的に簡単に形成するとともに、形成された中底体において、拇指球から小指球のラインを含む前方部分を屈曲容易とし、中足骨から踵の後方部分は硬度を大きくするという効果を奏する中底体、中敷体、それらを適用した履物を提供することを目的とする。 Accordingly, the present invention has been made in view of the above problems, and a smooth and completely integrated three-dimensional solid shape along the sole surface, which has been insufficient with the prior art, is mechanically simple in one step. In the formed insole, in the formed insole, it is easy to bend the front part including the line of the thumb ball to the little finger ball, and the back part of the heel from the metatarsal bone has the effect of increasing the hardness, The purpose is to provide insoles and footwear to which they are applied.
上記目的を達成するため、本発明の履物の中底体は、拇指球から小指球が当接する箇所を含む前方部分と、中足骨から踵が当接する箇所を含む後方部分を備えた履物の中底体において、 前方部分から後方部分まで連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体とし、二色成形によって前方部分の成形素材と後方部分の成形素材が異なり、後方部分の素材の硬度よりも前方部分の素材の硬度が小さく調整されており、全体が連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体でありながら、拇指球から小指球に当接する立体的形状の箇所において屈曲しやすく、中足骨から踵が当接する立体的形状の箇所は硬度を保ちやすい構造であることを特徴とする。
足裏に沿うような金型を用意すれば、全体が連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体を形成することができ、二色成形として、前方部分に射出または押し出す素材と後方部分に射出または押し出す素材をそれぞれ適度な硬度となる素材を選択して成形すれば、拇指球から小指球に当接する立体的形状の箇所において屈曲しやすくかつ中足骨から踵が当接する立体的形状の箇所は硬度を保ちやすい構造体を機械的な製造工程で簡単に製造できる。
In order to achieve the above object, the midsole of the footwear of the present invention comprises an anterior portion including a portion where the little ball comes into contact with the thumb ball and a rear portion including a portion where the heel comes into contact with the metatarsal bone. In the mid-sole body, it is a three-dimensional integrally molded structure with smooth irregularities that follow the sole shape continuously and integrally from the front part to the rear part, and molding of the molding material of the front part and the rear part by two-color molding The material is different, the hardness of the material of the front part is adjusted to be smaller than the material of the material of the back part, and the whole is integrally molded structure with a three-dimensional shape with smooth unevenness along the sole shape continuously and integrally However, it is characterized in that it is easy to bend at a three-dimensionally shaped portion that comes into contact with the little finger ball from the thumb ball, and a three-dimensionally shaped portion that comes into contact with the heel from the metatarsal bone has a structure that can easily maintain hardness.
If you prepare a mold that fits along the sole, you can form a three-dimensional integrally molded structure with smooth irregularities that follow the sole shape as a whole, and as a two-color molding, If a material that has an appropriate hardness is selected for the material that is injected or extruded to the front part and the material that is injected or extruded to the rear part, it is easy to bend at the three-dimensional shape that touches the little finger ball from the thumb ball. A three-dimensionally shaped portion where the heel comes into contact with the foot bone can be easily manufactured by a mechanical manufacturing process that can easily maintain the hardness.
例えば、前方部分の素材として、人体に無害で、弾力性、屈曲性があり、硬度を調整できるものであれば採用できるが、例えば、硬度を調整したポリエチレンテレフタレート、天然ゴム、塩化ビニル、スチレン・ブタジエンゴム、イソプレンゴム、ウレタンゴム素材のいずれかまたはその組み合わせ素材を採用することができる。これら素材は適度な硬度に調整でき、弾力性、屈曲性など、拇指球から小指球が当接する箇所の中底として適度な硬度と柔軟性を奏するものとすることができる。硬度の調整は、添加する可塑剤の量、成形時の温度、添加する熱硬化性素材の量などで調整可能である。 For example, as the material of the front part, it can be adopted as long as it is harmless to the human body, has elasticity and flexibility, and can adjust the hardness. For example, polyethylene terephthalate with adjusted hardness, natural rubber, vinyl chloride, styrene Any of butadiene rubber, isoprene rubber, urethane rubber material, or a combination thereof can be adopted. These materials can be adjusted to an appropriate hardness, and can have an appropriate hardness and flexibility as an insole where the little ball comes into contact with the little ball, such as elasticity and flexibility. The hardness can be adjusted by the amount of plasticizer to be added, the temperature during molding, the amount of thermosetting material to be added, and the like.
後方部分の素材としても、人体に無害で、弾力性、屈曲性があり、硬度を調整できるものであれば採用できるが、例えば、硬度を大きくなるよう調整したポリエチレンテレフタレート、天然ゴム、塩化ビニル、スチレン・ブタジエンゴム、イソプレンゴム、ウレタンゴム素材のいずれかまたはその組み合わせ素材を採用することができる。これら素材も同様に、適度な硬度に調整でき、弾力性、屈曲性など、拇指球から小指球が当接する箇所の中底として適度な硬度と柔軟性を奏するものとすることができる。硬度の調整は、添加する可塑剤の量、成形時の温度、添加する熱硬化性素材の量などで調整可能である。
なお、後方素材は、硬度を大きくする必要があり、例えば、補強材として、後方部分の一部に硬度の大きな金属製または樹脂製の棒材を内部に仕込んだ構造とすることも可能である。
As the material of the rear part, it can be adopted as long as it is harmless to the human body, has elasticity and flexibility, and can adjust the hardness, but for example, polyethylene terephthalate adjusted to increase the hardness, natural rubber, vinyl chloride, Any of styrene / butadiene rubber, isoprene rubber, urethane rubber material, or a combination thereof can be used. Similarly, these materials can be adjusted to an appropriate hardness, and can exhibit an appropriate hardness and flexibility as an insole where the little ball comes into contact with the little ball, such as elasticity and flexibility. The hardness can be adjusted by the amount of plasticizer to be added, the temperature during molding, the amount of thermosetting material to be added, and the like.
In addition, it is necessary to increase the hardness of the rear material. For example, as a reinforcing material, it is also possible to have a structure in which a metal or resin bar material having a high hardness is charged inside a part of the rear portion. .
また、中底体の厚みについても工夫を行うことができる。
中底体の前方部分の厚みを後方部分の厚みよりも薄くなるよう調整すれば、前方部分は屈曲しやすくなる。
Moreover, it can devise also about the thickness of a midsole.
If the thickness of the front portion of the midsole is adjusted to be thinner than the thickness of the rear portion, the front portion is easily bent.
次に、上記した構造を中敷として提供することもできる。
つまり、本発明の履物用の中敷体は、拇指球から小指球が当接する箇所を含む前方部分と、中足骨足裏から踵が当接する箇所を含む後方部分を備えた履物の中底体の上に装着する中敷体において、前方部分から後方部分まで連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体とし、二色成形によって前方部分の成形素材と後方部分の成形素材が異なり、後方部分の素材の硬度よりも前方部分の素材の硬度を小さく調整されており、全体が連続一体的に前記足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体でありながら、拇指球から小指球に当接する立体的形状の箇所において屈曲しやすく、中足骨足裏から踵が当接する立体的形状の箇所は硬度を保ちやすい構造であることを特徴とする。
足裏に沿うような金型を用意すれば、全体が連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体を形成することができ、二色成形として、前方部分に射出または押し出す素材と後方部分に射出または押し出す素材をそれぞれ適度な硬度となる素材を選択して成形すれば、機械的な製造工程で簡単に製造できる。
Next, the above-described structure can be provided as an insole.
That is, the insole body for footwear of the present invention is an insole of footwear including a front portion including a portion where the little ball comes into contact with the thumb ball and a rear portion including a portion where the foot comes into contact with the metatarsal foot sole. In the insole body to be mounted on the body, it is a three-dimensional integrally molded structure with smooth irregularities along the sole shape continuously and integrally from the front part to the rear part, and molding the front part by two-color molding The material and the molding material of the rear part are different, the hardness of the material of the front part is adjusted to be smaller than the hardness of the material of the rear part, and the whole is a solid with smooth unevenness that conforms to the sole shape continuously and integrally A structure that is easy to bend at a three-dimensional shape that comes into contact with the little finger ball from the thumb ball and that has a three-dimensional shape that comes into contact with the heel from the foot of the metatarsal bone while maintaining a hardness. It is characterized by being.
If you prepare a mold that fits along the sole, you can form a three-dimensional integrally molded structure with smooth irregularities that follow the sole shape as a whole, and as a two-color molding, If a material having an appropriate hardness is selected for the material that is injected or extruded to the front part and the material that is injected or extruded to the rear part, the material can be easily manufactured by a mechanical manufacturing process.

ここでは、婦人靴への適用を例として説明するが、紳士靴や運動靴であっても同様に適用することができる。
Hereinafter, with reference to the drawings, embodiments of the insole, insole, and footwear including them according to the present invention will be described. However, it goes without saying that the scope of the present invention is not limited to the specific application, shape, number, etc. shown in the following examples.
Here, application to women's shoes will be described as an example, but even men's shoes and sports shoes can be similarly applied.
実施例１として、本発明の履物用の中底体の基本構成について説明する。
図１は本発明の実施例１に係る履物用の中底体１００の構造を簡単に示す図である。婦人靴の例となっている。図１（ａ）は上面図、図１（ｂ）は底面図、図１（ｃ）は斜視図となっている。
As Example 1, the basic structure of the midsole for footwear of the present invention will be described.
FIG. 1 is a diagram simply showing the structure of an insole 100 for footwear according to a first embodiment of the present invention. It is an example of women's shoes. 1A is a top view, FIG. 1B is a bottom view, and FIG. 1C is a perspective view.
図１に示すように、履物用の中底体１００は、前方部分１１０、後方部分１２０、シャンク１３０を備えた構造となっている。
なお、上記構成は、表面や底面に何も貼付していないが、不織布を貼付したりクッション性を高めるためのスポンジ材を貼付したりすることは可能であり、本発明でもそれら他の素材を貼付しても良い。
履物用の中底体１００の前方部分１１０と後方部分１２０は二色成形により一体的に射出成形または押し出し成形で製造されている。
なお、図１では、前方部分１１０と後方部分１２０の違いを示すために、図のハッチングの付し方を変えているため、はっきりと異なるものとなっているが、実際の前方部分１１０と後方部分１２０は連続一体的に形成されており、色彩などは同じものに仕上げることができ、その場合、一見すると両者の境目が分からない場合もあり得る。
As shown in FIG. 1, the midsole body 100 for footwear has a structure including a front portion 110, a rear portion 120, and a shank 130.
The above configuration has nothing attached to the front or bottom surface, but it is possible to apply a nonwoven fabric or a sponge material for enhancing cushioning, and in the present invention, these other materials are also used. It may be affixed.
The front portion 110 and the rear portion 120 of the midsole 100 for footwear are manufactured by injection molding or extrusion molding integrally by two-color molding.
In FIG. 1, in order to show the difference between the front portion 110 and the rear portion 120, the hatching in the figure is changed, so that it is clearly different, but the actual front portion 110 and the rear portion are different. The portion 120 is formed continuously and integrally, and can be finished in the same color and the like. In that case, the boundary between the two may not be known at first glance.
前方部分１１０は、拇指球から小指球が当接する箇所を含む部分である。図１には当該箇所がざっくりと示されており、前方部分１１０は当該箇所を含んだものとなっていることが分かる。なお、中足骨骨頭はその下方にある拇指球から小指球と関節を形成しており、この関節部分において足先が大きく屈曲する関節であるので、拇指球から小指球が当接する箇所は、中足骨骨頭に相当する部分と言い換えることも可能である。
後方部分１２０は、前方部分から一体につながる部分であり、踵の当接箇所までつながる部分である。後方部分１２０は、簡単に言えば、前方部分１１０からシームレスに後方へつながる部分である。
前方部分１１０から後方部分１２０まで連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体となっている。
The front portion 110 is a portion including a portion where the little finger ball comes into contact with the thumb ball. FIG. 1 shows the portion roughly, and it can be seen that the front portion 110 includes the portion. The metatarsal bone head forms a joint with the little ball from the lower ball of the metatarsal, and since the tip of the foot is greatly bent at this joint part, the place where the little ball touches from the ball is It can be paraphrased as the portion corresponding to the metatarsal head.
The rear portion 120 is a portion that is integrally connected from the front portion, and is a portion that is connected to the contact portion of the heel. Simply put, the rear portion 120 is a portion that seamlessly connects to the rear from the front portion 110.
From the front part 110 to the rear part 120, it is a three-dimensional integrally formed structure having smooth irregularities along the sole shape.
ここで、前方部分１１０から後方部分１２０まで一体成形構造体となっているが、二色成形によるものとし、前方部分１１０の成形素材と、後方部分１２０の成形素材を異なるものとしている。
前方部分１１０の成形素材は、屈曲性に富み、屈曲を繰り返しても割れたり裂けたりしない柔軟性がある素材であり、その硬度が人の歩行の際の足先の屈曲の圧力で適度に追随して屈曲できる程度の硬度であれば良い。
例えば、前方部分１１０の成形素材として、ポリエチレンテレフタレート、天然ゴム、塩化ビニル、スチレン・ブタジエンゴム、イソプレンゴム、ウレタンゴム等などがあり得る。
Here, although it is an integrally molded structure from the front part 110 to the rear part 120, it is based on two-color molding, and the molding material of the front part 110 and the molding material of the rear part 120 are different.
The molding material of the front part 110 is a flexible material that is flexible and will not crack or tear even if it is repeatedly bent, and its hardness follows the pressure of the toes flexing while walking. It is sufficient if the hardness is such that it can be bent.
For example, polyethylene terephthalate, natural rubber, vinyl chloride, styrene / butadiene rubber, isoprene rubber, urethane rubber, or the like can be used as a molding material for the front portion 110.
ここで、後方部分１２０と前方部分１１０との硬度の違いが重要である。前方部分１１０の素材の硬度は、後方部分１２０の素材の硬度よりも小さく調整されている。
前方部分１１０は、拇指球から小指球に当接する立体的形状の箇所を包含する部分であり、歩行のたびに当該箇所において屈曲を繰り返す必要がある。そのため、屈曲しやすい比較的柔らかい硬度に調整するが、一方、後半部分１２０は、中足骨の足裏（土踏まず）から踵が当接する箇所であり、当該箇所の立体的形状は足や体重をしっかりサポートするため、ある程度の硬度を保つ必要がある。つまり、前方部分１１０は、屈曲しやすく柔軟性に富むものであるが、後方部分１２０は、弾力性は有していても容易に屈曲したり変形したりしない程度の硬度を保つものであり、両者の物性が異なるように仕上げられている。
Here, the difference in hardness between the rear portion 120 and the front portion 110 is important. The hardness of the material of the front portion 110 is adjusted to be smaller than the hardness of the material of the rear portion 120.
The front portion 110 is a portion including a three-dimensionally shaped portion that comes into contact with the little finger ball from the thumb ball, and it is necessary to repeatedly bend the portion at every walking. Therefore, it is adjusted to a relatively soft hardness that is easy to bend. On the other hand, the second half portion 120 is a portion where the heel comes into contact with the sole (arch) of the metatarsal bone, and the three-dimensional shape of the portion is the foot and weight. In order to support it firmly, it is necessary to maintain a certain degree of hardness. That is, the front portion 110 is easy to bend and rich in flexibility, but the rear portion 120 maintains elasticity to the extent that it does not easily bend or deform even if it has elasticity. Finished with different physical properties.
硬度の調整は、それら上記の主素材に添加する可塑剤の量、成形時の温度、添加する熱硬化性素材の量などで調整可能である。適度な硬度に調整すれば、前方部分１１０として所望の弾力性、屈曲性などが得られ、拇指球から小指球が当接する箇所の中底として適度な硬度と柔軟性を奏するものとすることができる。 The adjustment of the hardness can be adjusted by the amount of the plasticizer added to the main materials, the temperature at the time of molding, the amount of the thermosetting material to be added, and the like. If the hardness is adjusted to an appropriate level, desired elasticity and flexibility can be obtained as the front portion 110, and an appropriate hardness and flexibility can be achieved as a midsole where the little ball comes into contact with the thumb ball. it can.
このように、前方部分１１０と後方部分１２０で物性の異なるものと作り込むことができる一方で、両者はシームレスで全体が連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状となっている。両者の境界において平面ではなく起伏のある３次元立体形状をしており、かつ、つなぎ目が存在せず、シームレスで全体が連続一体的に足裏形状に沿う滑らかな凹凸の立体的形状となっている。 Thus, while the front portion 110 and the rear portion 120 can be made different in physical properties, the two are seamless and the three-dimensional shape with smooth unevenness that continuously and integrally follows the sole shape. It has become. It has a three-dimensional solid shape that is not a flat surface at the boundary between the two, and there are no joints, and it is a seamless three-dimensional shape that is seamless and entirely conforms to the sole shape. Yes.
このように、両者の境界においてつなぎ目が無いようにシームレスなものとしながらも、全体として前方部分１１０の厚みを薄く、後方部分１２０の厚みよりも薄くなるよう調整することが好ましい。柔軟性や屈曲性は厚みが薄い方が優れているので前方部分１１０の厚みが薄くし、足や体重をしっかりサポートする構造的強度は厚みが厚い方が優れているので後方部分１２０の厚みを厚くする工夫である。 As described above, it is preferable to adjust the thickness of the front portion 110 to be thinner than the thickness of the rear portion 120 as a whole while making it seamless so that there is no joint at the boundary between the two. The thinner the thickness, the better the flexibility and flexibility, and the thinner the front part 110. The thicker the structural strength to support the foot and body weight, the better the thickness of the rear part 120. It is a device to make it thicker.
次に、シャンク１３０を説明する。シャンク１３０は、後方部分１２０の一部に仕込まれた硬質素材である。素材は硬質素材であれば限定されないが、この実施例では、例えば、スチール製や、硬質プラスチック樹脂素材などで良い。形状は棒材や板材で良い。 Next, the shank 130 will be described. The shank 130 is a hard material charged in a part of the rear portion 120. The material is not limited as long as it is a hard material, but in this embodiment, for example, steel or a hard plastic resin material may be used. The shape may be a bar or plate.
歩行時の中底体１００の変形について述べる。
歩行時に体重が足先にかかり、足先の付け根、つまり、拇指球から小指球のラインが大きく屈曲した状態になった場合、中底体１００は、前方部分１１０の拇指球から小指球に当接する箇所において柔軟に大きく屈曲する。つまり、歩行のたびに繰り返される足先の屈曲運動に追従できる。一方、後方部分１２０は、硬度が比較的大きく、あまり屈曲はしないので、歩行のたびに繰り返される踵の着地から踏みしめにおいて、しっかりと足や体重をサポートしやくなっている。
The deformation of the midsole 100 during walking will be described.
When the body weight is applied to the toes during walking and the base of the toes, that is, the line from the thumb ball to the little finger ball is greatly bent, the midsole 100 hits the little ball from the thumb ball of the front portion 110. Bends flexibly and flexibly at the point of contact. That is, it is possible to follow the bending motion of the toes that is repeated every time walking. On the other hand, the rear portion 120 is relatively large in hardness and does not bend so much that it is easy to support the foot and weight firmly when stepping from the landing of the heel repeated every time walking.
図２〜図３は、実際に試作した模型の一例を示した図である。
図２〜図３に示す模型では、前方部分１１０と後方部分１２０の違いを示すために、異なる色を付して製作しているため、はっきりと境界が見えるものとなっているが、実際の前方部分１１０と後方部分１２０は、同じ色彩で連続一体的に形成すれば、一見すると両者の境目が分からない場合もあり得る。
図２〜図３に示すように、二色成形によって前方部分の成形素材と後方部分の成形素材が異なり、後方部分の素材の硬度よりも前方部分の素材の硬度が小さく調整されており、全体が連続一体的に足裏形状に沿う滑らかな凹凸を備えた立体的形状の一体成形構造体でありながら、拇指球から小指球に当接する立体的形状の箇所において屈曲しやすく、中足骨から踵が当接する立体的形状の箇所は硬度を保ちやすい構造となっている。
2 to 3 are diagrams showing an example of a model actually made as a prototype.
In the model shown in FIG. 2 to FIG. 3, in order to show the difference between the front part 110 and the rear part 120, since it is manufactured with different colors, the boundary can be clearly seen. If the front part 110 and the rear part 120 are continuously formed integrally with the same color, there may be a case where the boundary between the two is not apparent at first glance.
As shown in FIGS. 2 to 3, the molding material of the front part and the molding material of the rear part are different by two-color molding, and the hardness of the material of the front part is adjusted to be smaller than the hardness of the material of the rear part. Although it is a three-dimensional integrally molded structure with smooth irregularities along the sole shape, it is easy to bend at the three-dimensional shape that contacts the little finger ball from the thumb ball, and from the metatarsal bone The three-dimensional shape where the heel contacts is structured to maintain hardness.
実施例２として、本発明の履物用の中敷体について説明する。
中敷体は、中底１００の上面に設けるものである。製品によっては、中敷体の上にさらにクッション層を設けるものもある。中底体１００、中敷体とも、履物の部材の名称であり、層状に重ね合わせられるものである。そのため、拇指球から小指球のラインの屈曲性の問題は同じである。そこで、中敷体においても、全体を足裏の３次元立体形状に沿わして滑らかに一体的に形成しつつも、前方部分と後方部分の硬度を変えて前方部分の屈曲性を向上した方が良い場合もある。つまり、中敷体についても、前方部分には歩行の足先の屈曲への追従性が求められる。後方部分には中底体１００により足や体重がしっかりとサポートされるが、中敷体の後方部分自体も足や体重をしっかりサポートするためある程度の硬度があった方が良いと言える。
中敷体の製造においても、素材としてポリウレタンゴム、天然ゴム、スチレン・ブタジエンゴム、イソプレンゴムなどでそれら素材を射出成形または押し出し成形で形成する場合、実施例１と同様に二色成形にて前方部分と後方部分の素材の硬度を変えて一体成形することは製造工程上可能である。
そこで、実施例１に示した中底１００と同様に、前方部分と後方部分を備えた構造とし、中敷体の前方部分と後方部分は二色成形により一体的に射出成形または押し出し成形で製造されているものとして作り込んで提供すれば良い。
As Example 2, an insole for footwear of the present invention will be described.
The insole body is provided on the upper surface of the insole 100. Some products provide a cushion layer on the insole. Both the insole body 100 and the insole body are names of footwear members and are layered. Therefore, the problem of flexibility of the line from the thumb ball to the little finger ball is the same. Therefore, even in the insole body, the whole part is formed smoothly along the three-dimensional shape of the sole, and the front part and the rear part are changed in hardness to improve the flexibility of the front part. May be good. That is, for the insole body, the front portion is required to be able to follow the bending of the toes of walking. Although the foot and weight are firmly supported by the insole body 100 in the rear part, it can be said that the rear part itself of the insole body should have a certain degree of hardness in order to support the foot and weight firmly.
Also in the production of the insole body, when the material is formed by injection molding or extrusion molding using polyurethane rubber, natural rubber, styrene / butadiene rubber, isoprene rubber, etc. It is possible in the manufacturing process to integrally mold the material of the part and the rear part by changing the hardness.
Therefore, similarly to the insole 100 shown in the first embodiment, a structure having a front part and a rear part is provided, and the front part and the rear part of the insole body are integrally manufactured by injection molding or extrusion molding by two-color molding. It may be provided as a built-in product.

また、実施例３として、実施例１に示した中底体と実施例２に示した中敷体を含む履物として提供することもできる。履物として必要な他の部材、例えば、靴底、ヒール、実施例１に示した中底体１００、実施例２に示した中敷体２００、必要なアッパー部材などを組み上げて製造すれば良い。
Example 3 is a footwear including the midsole 100 shown in Example 1. What is necessary is just to assemble and manufacture other members required as footwear, for example, a shoe sole, a heel, the insole body 100 shown in Example 1, an insole, an upper, etc.
Moreover, as Example 3, it can also be provided as footwear including the insole shown in Example 1 and the insole shown in Example 2. What is necessary is just to assemble and manufacture other members required as footwear, for example, a shoe sole, a heel, the insole body 100 shown in Example 1, the insole body 200 shown in Example 2, and a necessary upper member.
以上、本発明の履物用の中底体、中敷体、それらを適用した履物の構成例における好ましい実施例を図示して説明してきたが、本発明の技術的範囲を逸脱することなく種々の変更が可能であることは理解されるであろう。 As described above, the preferred embodiments of the insole for the footwear of the present invention, the insole, and the configuration example of the footwear to which the footwear is applied have been illustrated and described, but various modifications can be made without departing from the technical scope of the present invention.
