About what

突起を有する靴用中敷きは従来から広く使用されており、また、それに関する提案も多数見受けられる。そして、その素材はほとんどが硬質ゴムや合成樹脂あるいはパラフィン系ワックスで、成形したものがほとんどである。(例えば、特許文献1、2参照)。   Shoe insoles having protrusions have been widely used in the past, and there are many proposals related thereto. And most of the materials are hard rubber, synthetic resin or paraffin wax, and most of them are molded. (For example, refer to Patent Documents 1 and 2).

しかしながら、上記素材からなる成形品の靴用中敷きは、劣化しやすいという致命的欠点がある。また、素材のためであると思われるが、比較的硬く、全体のクッション性に欠けているものも多い。   However, a shoe insole made of the above-mentioned material has a fatal defect that it easily deteriorates. In addition, although it seems to be due to the material, there are many that are relatively hard and lack overall cushioning properties.

本考案はこの欠点を解消することを目的とするものである。すなわち、従来の硬質ゴムや合成樹脂あるいはパラフィン系ワックスからなる場合に比べて軟らかくてクション性に優れ、なおかつ、足裏のつぼを適度に刺激することができる靴用中敷きを提供できるようにするとともに、極めて簡単に靴用中敷きを得ることができるようにしたものである。   The present invention aims to eliminate this drawback. That is, it is possible to provide an insole for shoes that is softer and more effective than conventional hard rubber, synthetic resin, or paraffin wax and that can moderately stimulate the sole of the sole. This makes it possible to obtain an insole for shoes very easily.

この目的を達成するために、本考案では、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とするポリマーを射出成形して架橋発泡させ、低発泡体の成型品である靴用中敷きとする。この場合には、ポリマーの射出成形による架橋発泡という極めて簡単な工程により、軟らかくてクション性に優れ、かつ極めて軽い靴用中敷きを得ることができる。また、耐摩耗性、耐防滑性、耐寒性、耐候性、耐薬品性に優れているのみならず、屈曲に対しても強靭である。   In order to achieve this object, in the present invention, a polymer mainly composed of an ethylene vinyl acetate copolymer and ethylene propylene rubber is injection-molded and crosslinked and foamed to form an insole for shoes which is a molded product of low foam. In this case, an insole for a shoe that is soft, excellent in crushability, and extremely light can be obtained by an extremely simple process of cross-linking foaming by injection molding of a polymer. In addition to being excellent in wear resistance, anti-slip resistance, cold resistance, weather resistance and chemical resistance, it is also strong against bending.

そして、平坦な中敷き本体1の上面から複数段に突出する膨出部2が一体的に形成されている。従って、この靴用中敷きを用いると、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とするポリマーからなる複数段の膨出部2で、足裏のつぼをより刺激することができる。   And the bulging part 2 which protrudes in multiple steps from the upper surface of the flat insole main body 1 is integrally formed. Therefore, when this insole for shoes is used, the vase of the sole can be further stimulated by the multi-stage bulging portion 2 made of a polymer mainly composed of an ethylene vinyl acetate copolymer and ethylene propylene rubber.

足裏のつぼに対応させて、膨出部2の段ごとに硬さを異ならしめておくと良い。この靴用中敷きを用いると、足裏のつぼを一層刺激することができる。   It is preferable to make the hardness different for each step of the bulging portion 2 in correspondence with the pot on the sole of the foot. By using this insole for shoes, the pot on the sole can be further stimulated.

膨出部2の段ごとに、色を異ならしめておくと良い。このようにすると、カラフルな靴用中敷きとなり、デザイン的にも優れたものとなる。   It is preferable to make the color different for each step of the bulging portion 2. If it does in this way, it will become a colorful insole for shoes and it will become the thing excellent also in design.

低発泡体の平坦な中敷き本体1の裏面に、紙をプレスした層3を積層しておくと良い。 紙をプレスした層3が積層されていると、軟らかい中敷き本体1の裏面が紙をプレスした層3で保護されるのみならず、表側の複数段に突出する膨出部2に掛かる力が中敷き本体1より硬い裏面の層3にそのまま掛かるので、足裏のつぼをさらに一層刺激することができる。   It is good to laminate the layer 3 which pressed the paper on the back surface of the flat insole body 1 of a low foam. When the paper-pressed layer 3 is laminated, not only the back surface of the soft insole body 1 is protected by the paper-pressed layer 3, but also the force applied to the bulging portions 2 protruding in a plurality of steps on the front side Since it hangs directly on the layer 3 on the back surface that is harder than the main body 1, the pot on the sole can be further stimulated.

紙をプレスした層3の裏面に、布4をさらに積層しておくと良い。布4がさらに積層されていると、中敷き本体1より硬い層3の裏面がこの布4で保護されるので、紙をプレスした層3が摩耗するのを防止できる。   A cloth 4 may be further laminated on the back surface of the layer 3 pressed with paper. If the cloth 4 is further laminated, the back surface of the layer 3 that is harder than the insole body 1 is protected by the cloth 4, so that the layer 3 that presses the paper can be prevented from being worn.

請求項1記載の考案によれば、ポリマーの射出成形による架橋発泡という極めて簡単な工程により、軟らかくてクション性に優れ、かつ極めて軽い靴用中敷きを得ることができる。また、耐摩耗性、耐防滑性、耐寒性、耐候性、耐薬品性に優れているのみならず、屈曲に対しても強靭である。さらに、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とするポリマーからなる複数段の膨出部2により、足裏のつぼをより刺激することができる。   According to the first aspect of the present invention, it is possible to obtain an insole for a shoe that is soft, excellent in crushability, and extremely light by a very simple process of cross-linking foaming by injection molding of a polymer. In addition to being excellent in wear resistance, anti-slip resistance, cold resistance, weather resistance and chemical resistance, it is also strong against bending. Furthermore, the pot on the sole can be further stimulated by the multi-stage bulging portion 2 made of a polymer mainly composed of an ethylene vinyl acetate copolymer and ethylene propylene rubber.

請求項2記載の考案によれば、足裏のつぼを一層刺激することができる。   According to the second aspect of the invention, the sole of the sole can be further stimulated.

請求項3記載の考案によれば、カラフルな靴用中敷きとなり、デザイン的にも優れたものとなる。   According to the invention of claim 3, it becomes a colorful insole for shoes and is excellent in design.

請求項4記載の考案によれば、軟らかい中敷き本体1の裏面が紙をプレスした層3で保護されるのみならず、表側の複数段に突出する膨出部2に掛かる力が中敷き本体1より硬い裏面の層3にそのまま掛かるので、足裏のつぼをさらに一層刺激することができる。   According to the fourth aspect of the invention, not only the back surface of the soft insole body 1 is protected by the paper-pressed layer 3, but also the force applied to the bulging portions 2 protruding in a plurality of steps on the front side is greater than the insole body 1. Since it hangs on the hard back layer 3 as it is, the pot on the sole can be further stimulated.

請求項5記載の考案によれば、紙をプレスした層3が摩耗するのを防止できる。   According to the fifth aspect of the present invention, it is possible to prevent the layer 3 pressed from paper from being worn.

本考案に係る靴用中敷きの一例を示す斜視図である。It is a perspective view which shows an example of the insole for shoes which concerns on this invention. その平面図である。FIG. その底面図である。It is the bottom view. 図2のA−A、B−B部分の拡大平面図である。It is an enlarged plan view of the AA and BB part of FIG. 図4のC−C線切断部の端面図である。It is an end view of the CC line cutting part of FIG.

本考案に係る靴用中敷きの一例を、図面に基いて説明する。この靴用中敷きNは、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とするポリマーを射出成形して架橋発泡させた低発泡体の成型品である。   An example of an insole for shoes according to the present invention will be described with reference to the drawings. The insole N for shoes is a molded product of a low-foamed body obtained by injection-molding a polymer mainly composed of an ethylene vinyl acetate copolymer and ethylene-propylene rubber, and crosslinking and foaming.

ポリマーの射出成形による架橋発泡という極めて簡単な工程により、軟らかくてクション性に優れ、かつ極めて軽い靴用中敷きを得ることができる。また、耐摩耗性、耐防滑性、耐寒性、耐候性、耐薬品性に優れているのみならず、屈曲に対しても強靭である。   By an extremely simple process of cross-linking foaming by injection molding of a polymer, it is possible to obtain an insole for a shoe that is soft and excellent in traction and extremely light. In addition to being excellent in wear resistance, anti-slip resistance, cold resistance, weather resistance and chemical resistance, it is also strong against bending.

このように、エチレン酢酸ビニル共重合体(EVA)とエチレンプロピレンゴム(EPR)を主体とするポリマーを射出成形して架橋発泡させ、低発泡体の成型品である靴用中敷きとした場合には、従来の硬質ゴムや合成樹脂あるいはパラフィン系ワックスを主成分とする靴用中敷きに比べて、軟らかいものとなる。   In this way, when a polymer mainly composed of ethylene vinyl acetate copolymer (EVA) and ethylene propylene rubber (EPR) is injection-molded and crosslinked and foamed to form a low-foam molded insole for shoes. Compared with conventional insoles for shoes mainly composed of hard rubber, synthetic resin, or paraffinic wax, it becomes softer.

図1、図2に示すように、平坦な中敷き本体1の上面から複数段に突出する膨出部2が全体にわたって多数一体的に形成されている。従って、この靴用中敷きNを用いると、エチレン酢酸ビニル共重合体とエチレンプロピレンゴムを主体とするポリマーからなる複数段の膨出部2で、足裏のつぼをより刺激することができる。   As shown in FIGS. 1 and 2, a large number of bulging portions 2 projecting in a plurality of stages from the upper surface of a flat insole body 1 are integrally formed. Therefore, when this insole N for shoes is used, the urn of the sole can be further stimulated by the multi-stage bulging portion 2 made of a polymer mainly composed of an ethylene vinyl acetate copolymer and ethylene propylene rubber.

足裏のつぼに対応させて、多数の膨出部2を中敷き本体1の全体にわたって配置することができる。また、多数の膨出部2の大きさを自由に変えることもできる。さらに、多数の膨出部2の高さを異ならしめることもできる。   A large number of bulging portions 2 can be arranged over the entire insole body 1 in correspondence with the soles of the soles. In addition, the size of the multiple bulges 2 can be freely changed. Furthermore, the height of many bulging parts 2 can also be varied.

図4、図5に拡大して示すように、ここには、リング状の部分が低い膨出部2aとなっており、その内側が前記膨出部2aより一段高い膨出部2bとなっている、膨出部2が二段の場合を例示しているが、その段数を三段以上にしても良いことは勿論である。ただし、低い一段の膨出部2aだけでは、足裏のつぼを刺激するのに適していないので、好ましくない。   As shown in enlarged views in FIGS. 4 and 5, the ring-shaped portion is a low bulge portion 2a, and the inside is a bulge portion 2b that is one step higher than the bulge portion 2a. Although the case where the bulging part 2 has two stages is illustrated, it is needless to say that the number of stages may be three or more. However, it is not preferable that only the lower one-stage bulging portion 2a is not suitable for stimulating the pot on the sole of the foot.

足裏のつぼに対応させて、膨出部2の段ごとに硬さを異ならしめておくことができる。この靴用中敷きNを用いると、足裏のつぼをさらに一層刺激することができる。膨出部2が二段の場合には、一段高い前記膨出部2bを硬くすると、前記効果が増大する。   The hardness can be made different for each step of the bulging portion 2 in correspondence with the pot on the sole of the foot. When the insole N for shoes is used, the pot on the sole can be further stimulated. In the case where the bulging portion 2 has two stages, the effect increases if the bulging portion 2b that is one step higher is hardened.

膨出部2の段ごとに、色を異ならしめておくことができる。膨出部2の段ごとに色を異ならしめておくと、カラフルな靴用中敷きNとなり、デザイン的にも優れたものとなる。 The color can be made different for each stage of the bulging portion 2. If the color is made different for each step of the bulging portion 2, it becomes a colorful insole N for shoes, which is excellent in design.

図1、図5に示すように、ここには、低発泡体の平坦な中敷き本体1の裏面に、紙をプレスした層3を積層した場合が例示されている。紙をプレスした層3が積層されていると、軟らかい中敷き本体1の裏面が紙をプレスした層3で保護されるのみならず、表側の複数段に突出する膨出部2に掛かる力が中敷き本体1より硬い裏面の層3にそのまま掛かるので、足裏のつぼをさらに一層刺激することができる。   As shown in FIGS. 1 and 5, here, a case where a layer 3 obtained by pressing paper is laminated on the back surface of a flat insole body 1 of a low foam is illustrated. When the paper-pressed layer 3 is laminated, not only the back surface of the soft insole body 1 is protected by the paper-pressed layer 3, but also the force applied to the bulging portions 2 protruding in a plurality of steps on the front side Since it hangs directly on the layer 3 on the back surface that is harder than the main body 1, the pot on the sole can be further stimulated.

また、図1、図3および図5に示すように、ここには、紙をプレスした層3の裏面に、布4をさらに積層した場合が例示されている。布4がさらに積層されていると、中敷き本体1より硬い層3の裏面がこの布4で保護されるので、紙をプレスした層3が摩耗するのを防止できる。   Further, as shown in FIGS. 1, 3 and 5, here, a case where a cloth 4 is further laminated on the back surface of the layer 3 pressed with paper is illustrated. If the cloth 4 is further laminated, the back surface of the layer 3 that is harder than the insole body 1 is protected by the cloth 4, so that the layer 3 that presses the paper can be prevented from being worn.

なお、図1、図2、図4に示すように、中敷き本体1の周囲には、細い凹凸模様5が多数形成され、また、図1〜図4に示すように、その内側を裏側にまで達する糸6が縫い付けられている。多数の細い凹凸模様5は、中敷き本体1の成形時において同時成形することができる。   1, 2, and 4, a large number of thin concavo-convex patterns 5 are formed around the insole body 1, and as shown in FIGS. 1 to 4, the inner side extends to the back side. The reaching thread 6 is sewn. Many thin uneven | corrugated patterns 5 can be shape | molded simultaneously at the time of shaping | molding of the insole main body 1. FIG.
