Description
本発明は、靴に装入して使用する中敷材であるインソールに関する。 The present invention relates to an insole, which is an inner sole material that is inserted into shoes.
従来から、靴の中敷材であるインソールとしては、単一素材で足型に切断した平面形状のものや、足裏の形状に合わせて足型凹面にしたカップインソール等がある。 Traditionally, insoles, which are the inner soles of shoes, have included flat insoles made of a single material cut to the shape of a foot, and cup insoles with a concave surface that matches the shape of the sole of the foot.
例えば、特許文献１（実開昭５４－３７３４０号）には、多層構成にして空間部を形成しクッション性及び通気性を向上させることを目的とした「履物底」が提案されている。 For example, Patent Document 1 (Japanese Utility Model Application Publication No. 54-37340) proposes a "footwear sole" that has a multi-layer structure to form spaces and improve cushioning and breathability.
また、特許文献２（実公平４－１８４０３号）では、３層以上重ねてなる多層カップインソールにおいて、非通気性で反発性素材の合成樹脂製である下層の足型凹面にした上面に、中央から側周囲へ連通して開口する溝を概略放射状で幅を広狭適宜に形成し、その上に不織布等の通気性素材で底面をフラットに形成した中間層を積層接着したものが提案されている。 Patent Document 2 (Jitsuhodo 4-18403) also proposes a multi-layered cup insole made of three or more layers, in which grooves of appropriate width are formed radially on the foot-shaped concave upper surface of the lower layer made of non-breathable, resilient synthetic resin, and the grooves open from the center to the sides, and an intermediate layer with a flat bottom surface made of a breathable material such as nonwoven fabric is laminated and bonded on top of the lower layer.
特許文献１及び２では、前記溝を、足指が位置する前半部ではこの前半部が加圧成型により肉薄で硬化しているため溝幅を広めに形成して屈曲性（柔軟性）と通気性を良好にし、踵部が位置する後半部ではこの後半部が肉厚であり保形性が低下しがちなため溝幅を狭く形成して保形性を損ねないようにしている。 In Patent Documents 1 and 2, the groove is made wider in the front half where the toes are located, because this front half is thin and hardened by pressure molding, to improve flexibility (flexibility) and breathability, and narrower in the rear half where the heel is located, because this rear half is thick and tends to lose shape retention, to prevent loss of shape retention.
しかしながら、足裏全体において通気性が十分とは言えず、ムレ易く、また、足裏とインソールとの間のグリップが不十分であり、即ち通気性及びグリップ性の観点から改善の余地があった。特に運動する者やアスリートにとっては、通気性及びグリップ性の両立が重要である。 However, the breathability of the sole of the foot is not sufficient, the sole tends to become stuffy, and the grip between the sole of the foot and the insole is insufficient, meaning there is room for improvement in terms of breathability and grip. Achieving both breathability and grip is particularly important for athletes and those who exercise.
そこで、本発明は、足裏全体において通気性が十分でムレにくく、また、足裏とインソールとの間のグリップ性が十分なインソールを提供することを目的とする。 Therefore, the present invention aims to provide an insole that has sufficient breathability over the entire sole of the foot, is less likely to become stuffy, and has sufficient grip between the sole of the foot and the insole.
上述した課題を解決すべく、本発明は、
表面に複数の凸状部が溝を介して並んで形成されており、
前記前記凸状部の頂部から前記溝の底部までが傾斜部で接続されていること、
を特徴とするインソール、を提供する。
In order to solve the above-mentioned problems, the present invention provides:
A plurality of convex portions are formed on the surface, arranged with grooves interposed therebetween,
a sloped portion is connected from the top of the convex portion to the bottom of the groove;
To provide an insole characterized by:
上記の本発明のインソールにおいては、
前記凸状部が、菱形、三角形又は円形であること、
が好ましい。
In the insole of the present invention,
The convex portion is a rhombus, a triangle, or a circle;
is preferred.
また上記の本発明のインソールにおいては、
前記凸状部の高さＨが０．０５ｍｍ～２．０ｍｍであり、
前記溝の幅Ｗ１が１．０ｍｍ～２．０ｍｍであり、
前記傾斜部の幅Ｗ２が式：Ｗ２＜Ｗ１を満たすこと、
が好ましい。
In addition, in the insole of the present invention,
The height H of the convex portion is 0.05 mm to 2.0 mm,
The width W1 of the groove is 1.0 mm to 2.0 mm,
The width W2 of the inclined portion satisfies the formula: W2<W1;
is preferred.
本発明に係るインソールは、サンダル、スポーツシューズ、ビジネスシューズ等の種々の履物に適用可能である。なかでもスポーツシューズ用に最適である。 The insole of the present invention can be applied to various types of footwear such as sandals, sports shoes, and business shoes. It is particularly suitable for sports shoes.
本発明によれば、上記のような構成を有することによって、足裏全体において通気性が十分でムレにくく、また、足裏とインソールとの間のグリップ性が十分なインソールを実現することができる。
According to the present invention, by having the above-mentioned configuration, it is possible to realize an insole that has sufficient breathability over the entire sole of the foot, is less likely to become stuffy, and has sufficient grip between the sole of the foot and the insole.
以下、本発明に係るインソールの代表的な実施形態を、図面を参照しつつ詳細に説明する。ただし、本発明はこれら図面に限定されるものではない。また、図面は、本発明を概念的に説明するためのものであるから、形状、寸法、比又は数を誇張又は簡略化して表している場合もある。 Below, a representative embodiment of the insole according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these drawings. Also, since the drawings are intended to conceptually explain the present invention, shapes, dimensions, ratios, or numbers may be exaggerated or simplified.
図１に、本発明の一実施形態にインソール１の表面の様子を示す概略斜視図を示す。図１に示すように、本実施形態に係るインソール１は、後方部分２において、左右及び後方の壁がやや起立しており、いわゆる「カップインソール」を構成している。 Figure 1 shows a schematic perspective view of the surface of an insole 1 according to one embodiment of the present invention. As shown in Figure 1, the left, right and rear walls of the rear portion 2 of the insole 1 according to this embodiment are slightly raised, forming a so-called "cup insole."
また、インソール１の表面（即ち使用者の足裏に接する面）には、全体において、複数の凸状部４が溝６を介して並んで形成されている。そして、凸状部４の上面から溝６の底部６ａまでが、凸状部４の全周にわたって傾斜部４ａで接続されている。 In addition, on the entire surface of the insole 1 (i.e., the surface that comes into contact with the sole of the user's foot), multiple convex portions 4 are formed side by side with grooves 6 interposed therebetween. The top surface of the convex portion 4 to the bottom 6a of the groove 6 is connected by an inclined portion 4a along the entire circumference of the convex portion 4.
つぎに、図２は、図１のインソール１の凸状部４及び溝６の部分の概略平面図である。本実施形態の凸状部４は菱形を有しており、上面が平面状である。インソール１においては、図１に示すように凸状部４の全周囲を囲うように溝６が設けられている。 Next, FIG. 2 is a schematic plan view of the convex portion 4 and the groove 6 of the insole 1 of FIG. 1. The convex portion 4 of this embodiment has a diamond shape and a flat upper surface. In the insole 1, the groove 6 is provided so as to surround the entire periphery of the convex portion 4 as shown in FIG. 1.
菱形の凸状部４については、長い対角線Ｄ１と短い対角線Ｄ２の２つの対角線を有しているが、長い対角線Ｄ１が概ねインソール１の長さ方向Ｌに平行になるように、全ての凸状部４が配置されている。また、溝６も凸状部４の全周囲を囲うように設けられている。 The diamond-shaped convex portion 4 has two diagonals, a long diagonal D1 and a short diagonal D2, and all of the convex portions 4 are arranged so that the long diagonal D1 is generally parallel to the longitudinal direction L of the insole 1. The groove 6 is also provided so as to surround the entire periphery of the convex portion 4.
このように、傾斜部４ａを有する菱形の凸状部４及び溝６が設けられていることにより、インソール１が使用者の足裏に接した場合に、凸状部４でグリップ性が担保され、また、溝６の部分で通気性が担保され、足裏のムレを効果的に抑制できる。 In this way, by providing the diamond-shaped convex portion 4 with the inclined portion 4a and the groove 6, when the insole 1 comes into contact with the sole of the user's foot, the convex portion 4 ensures grip, and the groove 6 ensures breathability, effectively preventing the sole of the foot from becoming stuffy.
次に、図３に、図１のＡ－Ａ線概略断面、即ちインソール１の後方部分２の表面足裏側に設けられた凸状部４及び溝６の構造を説明するための概略部分縦断面図を示す。 Next, FIG. 3 shows a schematic cross section taken along line A-A in FIG. 1, i.e., a schematic partial vertical cross section for explaining the structure of the convex portion 4 and groove 6 provided on the sole side of the surface of the rear portion 2 of the insole 1.
本実施形態においては、凸状部４の高さ（即ち、溝６の底部６ａから凸状部４の上面（頂点）までの距離）Ｈが０．０５ｍｍ～２．０ｍｍである。０．０５ｍｍ以上であれば、十分な溝６を確保できて十分な通気性が得られ、また、凸状部４の傾斜部４ａ及びエッジ部分を確保し易く、十分なグリップ性が得られる。２．０ｍｍ以下であると、凸状部４が安定感を有し、グリップ性を確保できる。 In this embodiment, the height H of the convex portion 4 (i.e., the distance from the bottom 6a of the groove 6 to the top surface (apex) of the convex portion 4) is 0.05 mm to 2.0 mm. If it is 0.05 mm or more, sufficient grooves 6 can be secured to obtain sufficient breathability, and the inclined portions 4a and edges of the convex portion 4 are easily secured, obtaining sufficient grip. If it is 2.0 mm or less, the convex portion 4 has a sense of stability and can ensure grip.
また、溝６（底部６ａ）の幅Ｗ１が１．０ｍｍ～２．０ｍｍであるのが好ましい。１．０ｍｍ以上であれば、溝６の十分な空間を確保できて通気性を担保することができ、また、２．０ｍｍ以下であると、溝６及び底部６ａが幅広くなり過ぎず、凸状部４の傾斜部４ａ及びエッジ部分を確保し易く、十分なグリップ性が得られる。 It is also preferable that the width W1 of the groove 6 (bottom 6a) is 1.0 mm to 2.0 mm. If it is 1.0 mm or more, sufficient space in the groove 6 can be secured to ensure breathability, and if it is 2.0 mm or less, the groove 6 and bottom 6a will not be too wide, making it easier to secure the inclined portion 4a and edge portion of the convex portion 4, and providing sufficient grip.
更に、傾斜部４ａの幅Ｗ２と溝６（底部６ａ）の幅Ｗ１とは、溝６及び底部６ａが幅広くなり過ぎず、凸状部４の傾斜部４ａ及びエッジ部分を確保し易く、十分なグリップ性が得られるという観点から、式：Ｗ２＜Ｗ１を満たすこと、が好ましい。 Furthermore, it is preferable that the width W2 of the inclined portion 4a and the width W1 of the groove 6 (bottom 6a) satisfy the formula: W2<W1, from the viewpoint that the groove 6 and bottom 6a are not too wide, the inclined portion 4a and the edge portion of the convex portion 4 are easily secured, and sufficient gripping properties are obtained.
なお、凸状部４の面積については、本発明の効果を損なわない範囲であれば特に制限は無いが、短い対角線Ｄ２が溝６（底部６ａ）の幅Ｗ１及び傾斜部４ａの幅Ｗ２に対して十分に長く、式：Ｗ２＜Ｗ１＜Ｄ２を満たしていればよい。 The area of the convex portion 4 is not particularly limited as long as it does not impair the effects of the present invention, but the short diagonal D2 must be sufficiently long relative to the width W1 of the groove 6 (bottom 6a) and the width W2 of the inclined portion 4a, and must satisfy the formula: W2<W1<D2.
以上、本発明の代表的な実施形態について説明したが、本発明はこれらに限定されるものではなく、種々の設計変更が可能であり、それらも本発明に含まれる。上記実施形態では凸状部４が菱形である場合について説明したが、凸状部は、正方形、三角形又は円形であってもよい。 The above describes typical embodiments of the present invention, but the present invention is not limited to these, and various design modifications are possible and are also included in the present invention. In the above embodiment, the convex portion 4 is described as having a diamond shape, but the convex portion may also be a square, triangular, or circular shape.
また、上記実施形態においては、インソール１が単一の層で構成されている態様について説明したが、複数の層で形成されていてもよく、その場合は、使用者の足裏に接する最表面に、上記実施形態で説明したインソール１が上層として配置されればよい。例えば、中間層や下層を有する３層構造のインストールであってもよい。 In the above embodiment, the insole 1 is described as being composed of a single layer, but it may be composed of multiple layers. In that case, the insole 1 described in the above embodiment may be disposed as the upper layer on the outermost surface that contacts the sole of the user's foot. For example, the insole may be a three-layer insole having a middle layer and a lower layer.
