Description

【0001】
【発明の属する技術分野】
本発明は屋内用シューズの靴底構造に関するものである。
【0002】
【従来の技術】
従来より、多数の波形状の凹溝を設けた靴底が知られている(特開平8−280406号公報参照)。この靴底は、凹溝に直交する方向に対しては、優れた防滑性を示す。
【0003】
【発明が解決しようとする課題】
しかし、前記従来の靴底は、凹溝に平行な方向についての防滑性が低い。また、濡れた床面に対する防滑性は比較的高いが、埃で汚れた床面での防滑性が低い。
【0004】
したがって、本発明の目的は、濡れた床面、ならびに、埃で汚れた床面の双方において優れた防滑性を呈する屋内用シューズの靴底構造を提供することである。
【0005】
【課題を解決するための手段】
前記目的を達成するために、本発明の屋内用シューズの靴底構造は、図1(b)の接地面10が略平坦な柱状の柱状凸部1と、先端20が尖った錐状の錐状凸部2とを混在させて配設すると共に、前記錐状凸部2の先端20を前記柱状凸部1の接地面10よりも若干突出させた靴底モジュールMを有する。
なお、図中の平面図においては、円の中心に小さな円または点を記入して錐状凸部2を表記している。
【0006】
つぎに、本靴底モジュールMによる防滑作用について説明する。
まず、濡れた床面では、靴底の接地時に、柱状凸部1が若干倒れながら、柱状凸部1のエッジ部11が床面上の水膜を掻き取り、該エッジ部11により水分が除去された床面に柱状凸部1の接地面10が吸い付くようにして防滑力を発揮する。また、図1(a)のように、多数の柱状凸部1が平面的に配列されていることで、あらゆる方向について前記防滑効果を発揮する。
【0007】
一方、埃で汚れた床面では、該埃の小さな粒子が「コロ」として働き、そのため、平坦な柱状凸部1では、柱状凸部1の接地面10と床面とが転がり接触するので、柱状凸部1の防滑作用が小さくなる。これに対し、本発明では、錐状凸部2の先端20が床面の埃を掻き分けるようにして床面に接触することで、防滑力を発揮する。
【0008】
本発明において、「柱状凸部」は、生産性の観点から略円柱形に設定する。一方、「錐状凸部」は、生産性の観点から略円錐形に設定する
【0009】
また、柱状凸部1の接地面10が「略平坦」であるとは、たとえば図1(c)のように、接地面10の中央が窪んだような形状であっても、全方向についての水切り作用を呈しうる程度の平坦な面を有していれば、本発明の範囲に含まれることを意味する。
【0010】
本発明の柱状凸部1が前記水切り作用を呈するには、柱状凸部1の接地面10の周縁に水切り用の鋭利なエッジ部11を形成しているのが好ましい。ここで、製造用の図面などにおいて、特別の指定をしない場合、角の部分11には小さなアール(R)やC面がJISの規格等に従って通常設けられるのに対し、本発明の「鋭利なエッジ部11」とは、前記通常設けられるアール(R)やC面を有していないものや、通常設けられるアールやC面よりも小さなアールやC面を有しているものをいう。
なお、前記鋭利なエッジ部11が磨り減って、通常のアール(R)やC面に近い状態となった後も、ある程度の防滑性を発揮するので、当初より、通常のアールやC面を有するものも本発明の範囲に含まれる。
【0011】
また、靴底の硬度は、JISA硬度で通常45度ないし80度程度のものが用いられるが、本発明では45°〜65°程度が好ましい。また、柱状凸部1が適度に倒れるためには、柱状凸部1の直径φは2〜9mm程度に設定され、その間の距離Dは、最接近部において0.3 〜1.7mm 程度が好ましく、また、柱状凸部1の高さHは1.0 〜3.0mm 程度が好ましい。
【0012】
また、水で濡れた床面において十分な防滑性を発揮させるためには、柱状凸部1の数を錐状凸部2の数よりも多く設けるのが好ましい。一方、埃で汚れた床面において十分な防滑性を発揮させるためには、錐状凸部2の数を凸部1,2全体の数に対し、錐状凸部2の割合を10%〜33%程度に設定し、13%〜20%程度とするのが好ましい。
【0013】
また、錐状凸部2の先端20の突出量H1は、埃を掻き分ける機能およびソールの安定性を考慮すると、0.1 〜1.0mm 程度に設定し、0.3 〜0.8mm 程度とするのが好ましい。
【0014】
本発明において、「靴底モジュールMを有する」とは、図2に示すように、靴底の略全域にわたる部分について、前述のような構造となっている場合の他に、図3に示すように、靴底の一部について前述のような構造となっているものを含むことを意味する。したがって、図3の靴底では9個の靴底モジュールM1〜M9を有するが、1以上の靴底モジュールMを有する靴底であれば本発明の範囲に含まれる。
【0015】
【発明の実施の形態】
図3は本発明の一実施形態を示す。
この図の靴底では9個の靴底モジュールM1〜M9を靴底本体3に固着して、アウターソールを構成している。なお、爪先部または母趾球部の靴底モジュールM1,M2については、他の靴底モジュールM3〜M9よりも硬度を大きくするか、あるいは、柱状凸部1の高さを低くするなどにより柱状凸部1が倒れにくくするのが好ましい。前記爪先部や母趾球部の靴底モジュールM1〜M2には、他の部分よりも瞬間的に大きな力が加わることが多いからである。
【0016】
【実施例】
以下、本発明の効果を明瞭にするために、実施例および比較例を示す。
実施例1〜5:
図2に示す靴底意匠を用い、硬度および錐状凸部2の比率(割合)を変化させた。なお、錐状凸部2の比率は凸部1,2の全体に対する比で示した。

なお、図1の寸法は下記の寸法のものを用いた。
H=2.0mm
φ=4mm
H1=0.5 mm
D=0.5 mm
【0018】
比較例1〜3:

【発明の効果】
以上説明したように、本発明によれば、水で濡れた床面では多数の柱状凸部のエッジが床面上の水分を掻き取って、該柱状凸部の接地面が滑るのを防止し、一方、埃で汚れた床面では錐状凸部の先端が埃の粒子または微粉末を掻き分けて床面に接触して防滑作用を発揮する。すなわち、本発明の靴底構造は、多数の柱状凸部および錐状凸部により、優れたウェットグリップ性およびダストグリップ性を発揮する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a shoe sole structure for indoor shoes.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a shoe sole provided with a number of corrugated grooves has been known (see Japanese Patent Application Laid-Open No. 8-280406). This sole has excellent anti-slip properties in a direction perpendicular to the groove.
[0003]
[Problems to be solved by the invention]
However, the conventional shoe sole has low slip resistance in a direction parallel to the groove. In addition, although the slip resistance on a wet floor is relatively high, the slip resistance on a dusty floor is low.
[0004]
Accordingly, an object of the present invention is to provide a shoe sole structure for indoor shoes that exhibits excellent anti-slip properties on both a wet floor surface and a dusty floor surface.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the shoe sole structure of the indoor shoe according to the present invention includes a columnar convex portion 1 having a substantially flat columnar contact surface 10 in FIG. The conical convex part 2 is provided in a mixed manner, and the tip 20 of the conical convex part 2 has a shoe sole module M slightly protruding from the contact surface 10 of the columnar convex part 1.
In the plan view in the figure, a small circle or a dot is drawn at the center of the circle to indicate the conical convex portion 2.
[0006]
Next, a description will be given of the anti-slipping effect of the sole module M.
First, on a wet floor surface, when the sole of the shoe touches the ground, the columnar convex portion 1 slightly falls down, and the edge portion 11 of the columnar convex portion 1 scrapes a water film on the floor surface, and the edge portion 11 removes moisture. The ground contact surface 10 of the columnar convex portion 1 adheres to the floor surface thus provided, thereby exerting an anti-slip force. In addition, as shown in FIG. 1A, the anti-slip effect is exhibited in all directions by arranging a large number of columnar projections 1 in a plane.
[0007]
On the other hand, on a floor surface that is contaminated with dust, the small particles of the dust function as “rollers”. Therefore, in the flat columnar convex portion 1, the ground contact surface 10 of the columnar convex portion 1 and the floor surface come into rolling contact with each other, The anti-slip effect of the columnar projection 1 is reduced. On the other hand, in the present invention, the tip end 20 of the conical convex portion 2 comes into contact with the floor surface in such a manner as to push out dust on the floor surface, thereby exerting an anti-slip force.
[0008]
In the present invention, "columnar protrusions" is set to be substantially cylindrical from the viewpoint of productivity. On the other hand, "conic protrusions" is set to be substantially conical in terms of productivity.
[0009]
The ground surface 10 of the columnar protrusion 1 is “substantially flat” even if the center of the ground surface 10 is depressed as shown in FIG. 1C, for example. It is included in the scope of the present invention if it has a flat surface capable of exhibiting the draining action.
[0010]
In order for the columnar convex portion 1 of the present invention to exhibit the water draining action, it is preferable that a sharp edge portion 11 for draining water is formed on the periphery of the grounding surface 10 of the columnar convex portion 1. Here, if there is no special designation in a drawing for manufacturing or the like, a small radius (R) or a C-plane is usually provided in the corner portion 11 according to JIS standards or the like, whereas the “sharp” of the present invention is used. The edge portion 11 "refers to an edge having no radius (R) or C-plane that is usually provided, or an edge having a radius or C-plane smaller than the radius or C-plane that is usually provided.
In addition, even after the sharp edge portion 11 is worn away and becomes in a state close to a normal radius (R) or a C-plane, a certain degree of slip resistance is exhibited. What has it is also included in the scope of the present invention.
[0011]
In addition, the hardness of the shoe sole is usually about 45 to 80 degrees in JISA hardness, but is preferably about 45 to 65 degrees in the present invention. In order for the columnar projection 1 to fall down appropriately, the diameter φ of the columnar projection 1 is set to about 2 to 9 mm, and the distance D between them is preferably about 0.3 to 1.7 mm at the closest part. The height H of the columnar projections 1 is preferably about 1.0 to 3.0 mm.
[0012]
Further, in order to exhibit sufficient slip resistance on a floor surface wet with water, it is preferable to provide a larger number of columnar projections 1 than a number of conical projections 2. Meanwhile, in order to exhibit sufficient anti-slip in floor contaminated with dust, a number of conical protrusions 2 with respect to the number of the convex portions 1 and 2 whole, the ratio of the cone-shaped convex portion 2 10% set to about -33%, to 13% to 20% of the favorable preferable.
[0013]
Further, the projecting amount H1 of the conic protrusions 2 of the tip 20, considering the stability of the function and a sole push aside dust, set to about 0.1 1.0 mm, better is good for about 0.3 to 0.8 mm No.
[0014]
In the present invention, "having the sole module M" means that, as shown in FIG. 2, a portion covering substantially the entire area of the sole has the above-described structure, and also has a structure as shown in FIG. In addition, it means that a part of the sole has a structure as described above. Therefore, the sole of FIG. 3 has nine sole modules M1 to M9, but a sole having one or more sole modules M is included in the scope of the present invention.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 3 shows an embodiment of the present invention.
In the sole of the figure, nine sole modules M1 to M9 are fixed to the sole body 3 to form an outer sole. The sole modules M1 and M2 of the toe or the ball of the toe have a columnar shape by making the hardness higher than the other sole modules M3 to M9, or by lowering the height of the columnar projections 1 or the like. It is preferable that the projection 1 is hard to fall down. This is because, in many cases, a greater force is applied to the shoe sole modules M1 and M2 of the toe portion and the ball of the toe instantaneously than other portions.
[0016]
【Example】
Hereinafter, in order to clarify the effects of the present invention, examples and comparative examples will be described.
Examples 1 to 5:
Using the shoe sole design shown in FIG. 2, the hardness and the ratio (ratio) of the conical convex portions 2 were changed. In addition, the ratio of the conical convex part 2 was shown by the ratio with respect to the whole convex part 1 and 2.
[0017]
The dimensions shown in FIG. 1 were as follows.
H = 2.0mm
φ = 4mm
H1 = 0.5 mm
D = 0.5 mm
[0018]
Comparative Examples 1-3:
A corrugated, honeycomb-shaped shoe sole design, or a shoe sole having no columnar projection but having a triangular pyramid-shaped projection was used.
[0019]
The subject wore shoes having the soles of the above Examples and Comparative Examples, and the wet grip performance and the dust grip performance were determined.
The test was carried out on a cherry blossom board which is generally used as a floor material for a gymnasium. The wet grip performance was evaluated by stepping on a sufficiently wet floor surface with a stride of 80 cm from an upright posture, measuring the distance that the shoe slid, and evaluating. In addition, the dust grip property is as follows. Stepping 80 cm from the standing position, stepping on the floor where dust of Antuca soil was sifted through a 250 μm sieve at a rate of 0.56 g / m 2 while changing the location little by little Was measured, and the distance the shoe slid when stepping on the 20th time was measured and evaluated. The grip on the normal floor is 80 cm from the standing position, with a stride of 80 cm, stepping on the floor that is not wet with water and dirty with dust, measure the distance the shoes have slipped, It was evaluated.
Table 1 shows the determination results.
[0020]
[Table 1]
Figure 0003566090
[0021]
【The invention's effect】
As described above, according to the present invention, on the floor surface wet with water, the edges of many columnar protrusions scrape off moisture on the floor surface and prevent the grounding surface of the columnar protrusions from slipping. On the other hand, on the floor surface that is contaminated with dust, the tip of the conical convex portion rakes out dust particles or fine powder and comes into contact with the floor surface to exert an anti-slip effect. That is, the shoe sole structure of the present invention exerts excellent wet grip performance and dust grip performance due to the large number of columnar convex portions and conical convex portions.
