Description

本発明は、水、油、溶剤、液状石鹸等の液体が付着して滑りやすい状態にある床面に対して滑り難くした耐滑性シート及びそれを靴底に使用した耐滑性靴に関するものである。   The present invention relates to a slip-resistant sheet that is difficult to slip on a floor surface that is in a slippery state due to adhesion of water, oil, solvent, liquid soap, or the like, and a slip-resistant shoe using the slip-resistant sheet. .

水、油、溶剤、石鹸等の液体が付着した床面が滑りやすいのは、床面に敷かれたシートとそれを人が踏む靴底の間、又はシートを敷いていない場合には靴底と床面の間に液体が介在するからであり、この液体をシート又は靴底の下部より速やかに排出することによって滑りを防止することができる。そこで、一般的に耐滑性シートや耐滑性靴は、シートと床面の間、あるいは靴底と床面の間に液体を排出させるための溝と凸部を設けてある。   The floor surface to which liquids such as water, oil, solvent, soap, etc. are slippery is slippery between the sheet laid on the floor surface and the shoe sole on which the person steps, or when the sheet is not laid This is because a liquid is interposed between the floor and the floor, and slipping can be prevented by quickly discharging the liquid from the lower part of the seat or the shoe sole. Therefore, in general, a slip resistant sheet or a slip resistant shoe is provided with a groove and a protrusion for discharging liquid between the seat and the floor surface or between the shoe sole and the floor surface.

しかし、人がシート等を踏む際にはシートや靴底に設けられた凸部が倒れ、その倒れた凸部の接地面と床面の間に液体が入るため逆に滑りやすくなるといった問題が生じる。
また、凸部の倒れをなくそうと、凸部も含め硬い材質で耐滑性シートや耐滑性靴を製作すると、凸部表面のグリップ力が低下して、滑りやすくなる。
However, when a person steps on a sheet or the like, the convex portion provided on the seat or the shoe sole falls, and there is a problem that liquid easily enters between the ground surface and the floor surface of the collapsed convex portion so that it is easy to slip. Arise.
Further, if a slip resistant sheet or a slip resistant shoe is made of a hard material including the convex portion so as to prevent the convex portion from collapsing, the grip force on the convex portion surface is lowered and the slip portion becomes slippery.

そこで、シートや靴に関して、耐滑性を高めるために様々な提案がされている。
このようなものには、横断面がV字形状の凸部を複数有し、それら凸部を所定間隔を設けて並べてなる耐滑性靴が知られている(例えば、特許文献1参照)。
特許第3959648号公報
Therefore, various proposals have been made on sheets and shoes in order to increase slip resistance.
As such, a slip-resistant shoe is known which has a plurality of convex portions having a V-shaped cross section and is arranged with a predetermined interval between the convex portions (for example, see Patent Document 1).
Japanese Patent No. 3959648

しかしながら、特許文献1に記載された耐滑性靴では、靴底にある液体を容易に排出できる方向と、そうではない方向がある(方向依存性がある)。
例えば、特許文献1に記載の発明は、横断面がV字形状の凸部を足長方向に所定間隔を設けて並べ、それを足幅方向に複数列配置する構成であるので、V字を形成する二本の壁部で囲まれた箇所に液体が溜まってしまう。すなわち、V字の開口部となる前方向には液体が流れやすいが、残りの3方向(後方向、右方向、左方向)は壁部により液体の流れが堰き止められる。
However, in the slip resistant shoe described in Patent Document 1, there are a direction in which the liquid in the sole can be easily drained and a direction in which the liquid is not so (there is direction dependency).
For example, the invention described in Patent Document 1 is a configuration in which convex portions having a V-shaped cross section are arranged at predetermined intervals in the foot length direction and arranged in a plurality of rows in the foot width direction. The liquid accumulates at a location surrounded by the two walls to be formed. That is, the liquid easily flows in the forward direction as the V-shaped opening, but the flow of the liquid is blocked by the wall in the remaining three directions (backward, rightward, and leftward).

そこで、本発明の目的とするところは、排水性に関して方向依存性の無い耐滑性シート及びそれを靴底に使用した耐滑性靴を提供することにある。   Accordingly, an object of the present invention is to provide a slip-resistant sheet having no direction dependency with respect to drainage and a slip-resistant shoe using the same for a shoe sole.

ここで、上記括弧内の記号は、図面および後述する発明を実施するための最良の形態に掲載された対応要素または対応事項を示す。   Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

請求項1に記載された耐滑性靴によれば、靴底に使用された耐滑性シートには、足幅方向に等間隔で足長方向に平行に形成された二以上の直線状の溝が形成されているので、靴を履いてユーザが前進するとき、液体が溝を通じて、後方の踵側端部から靴底外へ速やかに排出されるので、排出された液体が再び靴底と床面の間に入ることもない。
このように、滑り原因となる液体は靴底と床面の間に残らないので、優れた耐滑性靴が得られる。
また、凸部は隣接する二つの溝間に一列で配列され、しかも凸部同士は所定間隔をあけて互い違いにするように配列されているので、特許文献1で示したように、液体が靴底に留まる部位はない。つまり、液体は、溝及び凸部間の間隔を介して円滑に靴底外に流れ、どの方向に対しても、液体の流れを妨げるものが無いので耐滑性に優れる。
According to the slip resistant shoe described in claim 1, the slip resistant sheet used for the shoe sole has two or more linear grooves formed at equal intervals in the foot width direction and parallel to the foot length direction. Since the liquid is quickly discharged from the rear heel side end to the outside of the shoe sole through the groove when the user moves forward while wearing the shoes, the discharged liquid is again discharged from the shoe sole and the floor surface. I don't get in between.
As described above, since the liquid causing the slip does not remain between the shoe sole and the floor surface, an excellent slip resistant shoe can be obtained.
Further, since the convex portions are arranged in a row between two adjacent grooves, and the convex portions are arranged so as to be staggered at a predetermined interval, as shown in Patent Document 1, the liquid can be used as a shoe. There is no part that stays at the bottom. That is, the liquid smoothly flows out of the shoe sole via the gap between the groove and the convex portion, and since there is nothing that obstructs the flow of the liquid in any direction, the slip resistance is excellent.

それに加え、凸部にはスリットが設けられているので、スリットを境に、凸部の片側が倒れたとしても、もう片側が倒れないので床面とのグリップ力を保持できる。
また、凸部の接地面に付着した液体は、直接溝に流れ込むだけではなく、スリットにも流れ込む場合があるが、スリットの中に入った液体は、スリットと連通されている溝より靴底外へ排出されるので、耐滑性に優れる。
In addition, since the convex portion is provided with a slit, even if one side of the convex portion falls down with the slit as a boundary, the other side does not fall down, so that the grip force with the floor surface can be maintained.
In addition, the liquid adhering to the ground contact surface of the convex part may flow not only directly into the groove but also into the slit, but the liquid that has entered the slit is outside the shoe sole from the groove communicating with the slit. Excellent slip resistance.

また、複数の凸部を、足幅方向に隣接する二つの凸部における略二等辺三角形の頂角が溝に直交する直線上に位置するように配列したので、同じ向きの凸部が足幅方向に並んでいる。
このように凸部の向きが揃っているので、向きが揃っていないものと比較して、凸部を倒す力に対して抵抗力が強くなる。すなわち、歩行時により高いグリップ力を得ることができ、滑りにくくなる。
In addition, since the plurality of convex portions are arranged so that the apex angles of the substantially isosceles triangles in the two convex portions adjacent to each other in the foot width direction are located on a straight line orthogonal to the groove, the convex portions in the same direction have the foot width. It is lined up in the direction.
Thus, since the direction of a convex part is equal, compared with the thing where direction is not uniform, resistance force becomes strong with respect to the force which depresses a convex part. That is, a higher grip force can be obtained during walking, and it becomes difficult to slip.

請求項2に記載の耐滑性靴によれば、靴底に使用された耐滑性シートには、足長方向に等間隔で足幅方向に平行に形成された二以上の直線状の溝を形成してなるので、靴を履いて前進するとき、液体は靴底に留まることなく靴底足幅方向端部から靴底外へ速やかに排出される。すなわち、足長方向に平行に延びる溝を通じて踵側端部より排出しなければならない請求項1に記載の耐滑性靴に比べ、本請求項に係る靴では、足長方向のどの位置に存在する液体でも、足長方向よりも移動距離の短い足幅方向から靴底外に排出されるので、より素早く排水できる。
また、請求項1に記載の発明と同様に、隣接する二つの溝間に一列で、凸部同士が互い違いにするように配列されているので、どの方向に対しても、液体の流れを妨げるものが無い。すなわち、溝や、互い違いに配列された凸部間を液体が円滑に流れ、しかも前後左右どの方向に対しても妨げる壁部等は無いので耐滑性がある。
According to the slip-resistant shoe according to claim 2 , the slip-resistant sheet used for the shoe sole is formed with two or more linear grooves formed in parallel in the foot width direction at equal intervals in the foot length direction. Therefore, when the shoe advances while wearing the shoes, the liquid is quickly discharged from the shoe sole foot width direction end portion to the outside of the shoe sole without staying on the shoe sole. That is, in the shoe according to the present invention, the shoe according to the present invention is present at any position in the foot length direction as compared with the slip resistant shoe according to claim 1 , which must be discharged from the heel side end portion through a groove extending in parallel with the foot length direction. Even a liquid can be drained more quickly because it is discharged out of the sole from the width direction of the foot, which is shorter than the length direction of the foot.
Further, similarly to the first aspect of the invention, since the convex portions are arranged in a row between two adjacent grooves, the liquid flow is obstructed in any direction. There is nothing. That is, since the liquid smoothly flows between the grooves and the convex portions arranged alternately, there is no wall portion etc. that obstructs the front, rear, left, and right directions, so that it has slip resistance.

また、複数の凸部を、足長方向に隣接する二つの凸部における略二等辺三角形の頂角が溝に直交する直線上に位置するように配列したので、同じ向きの凸部が足長方向に並んでいる。このように凸部の向きが揃っていると、凸部を倒す力に対して、向きが揃っていないときよりも抵抗力が強くなる。すなわち、歩行時により高いグリップ力を得ることができ、滑りにくくなる。 In addition, since the plurality of protrusions are arranged so that the apex angles of the substantially isosceles triangles in the two protrusions adjacent in the foot length direction are located on a straight line orthogonal to the groove, the protrusions in the same direction are the foot length. It is lined up in the direction. Thus, if the direction of a convex part is equal, resistance will become strong with respect to the force which tilts a convex part rather than when the direction is not uniform. That is, a higher grip force can be obtained during walking, and it becomes difficult to slip.

請求項3に記載の耐滑性シートによれば、少なくとも片面に、縦方向に等間隔で横方向に平行に形成された二以上の直線状の溝が形成されているので、耐滑性シートを床面に敷いたとき、液体が溝を通じて、横方向端部から耐滑性シート外へ速やかに排出される。
また、隣接する二つの溝間に一列で、凸部同士が所定間隔をあけて互い違いにするように配列されているので、どの方向に対しても、液体の流れを妨げるものが無い。すなわち、溝や互い違いに向かい合った凸部間を液体が円滑に流れ、しかも前後左右どの方向に対しても妨げる壁部等は無いので耐滑性がある。
According to the slip-resistant sheet according to claim 3 , since the two or more linear grooves formed at equal intervals in the longitudinal direction and in parallel in the lateral direction are formed on at least one surface, the slip-resistant sheet is placed on the floor. When laid on the surface, the liquid is quickly discharged from the lateral end through the groove and out of the slip resistant sheet.
Further, since the convex portions are arranged in a row between two adjacent grooves so as to be staggered with a predetermined interval, there is nothing that obstructs the liquid flow in any direction. That is, the liquid smoothly flows between the grooves and the convex portions facing each other, and there is no wall portion or the like that obstructs the front, rear, left, and right directions, so that it has slip resistance.

それに加え、凸部にスリットが設けられているので、スリットを境に、凸部の片側が倒れたとしても、もう片側が倒れないので床面とのグリップ力を保持できる。
また、凸部の接地面に付着した液体は、直接溝に流れ込むだけではなく、スリットにも流れ込む場合があるが、スリットの中の液体は、スリットと連通されている溝より耐滑性シート外へ排出されるので耐滑性に優れる。
In addition, since the slit is provided in the convex part, even if one side of the convex part falls over the slit, the other side does not fall down, so that the grip force with the floor surface can be maintained.
In addition, the liquid adhering to the ground contact surface of the convex portion may not only flow directly into the groove but also flow into the slit, but the liquid in the slit moves out of the slip resistant sheet from the groove communicating with the slit. Since it is discharged, it has excellent slip resistance.

なお、本発明のように、方向依存性がなくどの方向に対しても円滑に排水しうる構成に関しては、上述した特許文献1には全く記載されていない。   Note that, as in the present invention, there is no description at all in the above-mentioned Patent Document 1 regarding a configuration that has no direction dependency and can be smoothly drained in any direction.

不踏部5の踵側境界線は、足幅方向に平行であり、不踏部5のつま先側境界線は、不踏部5の踵側境界線に対して靴底1の外側から内側にかけて間隔を狭くするように傾斜している。
The tread portion 5 is formed in a so-called arch portion between the toe side and the heel side of the shoe sole 1 from the left end to the right end in the foot width direction. That is, the plurality of convex portions 2 are not provided here.
The heel side boundary line of the tread portion 5 is parallel to the foot width direction, and the toe side boundary line of the tread portion 5 extends from the outer side of the shoe sole 1 to the inner side with respect to the heel side boundary line of the tread portion 5. It is inclined to narrow the interval.

溝3は、靴底1に、足幅方向に等間隔で足長方向に平行に形成された二以上の直線状に形成されている。それぞれの溝3は、靴底1のつま先側端部から不踏部5との境界線までと、踵側端部から不踏部5との境界線まではそれぞれつながっており、溝3内には液体7の流れを遮る障壁は無い。
ただし、不踏部5より踵側にある溝3は足長方向に平行であるが、不踏部5よりつま先側にある溝3の延びる方向は、不踏部5より踵側にある溝3の延びる方向に対して親指側に傾斜している。
The groove 3 is formed in the shoe sole 1 in two or more straight lines formed at equal intervals in the foot width direction and parallel to the foot length direction. Each groove 3 is connected from the toe side end of the shoe sole 1 to the boundary line with the treadle part 5 and from the heel side end part to the boundary line with the treadle part 5. There is no barrier to block the flow of liquid 7.
However, the groove 3 on the heel side from the non-stepping portion 5 is parallel to the foot length direction, but the extending direction of the groove 3 on the toe side from the non-stepping portion 5 is the groove 3 on the heel side from the non-stepping portion 5. It is inclined to the thumb side with respect to the extending direction.

また、溝3自体の幅は、不踏部5より踵側、不踏部5よりつま先側に関わらず全て等しい。しかも、隣接する溝3間も同様に全て等しい。
加えて、溝3の靴底1側奥の面は、靴底1厚さ方向に対して不踏部5と同じ高さである。
Further, the width of the groove 3 itself is the same regardless of the heel side from the non-stepping portion 5 and the toe side from the non-stepping portion 5. In addition, the adjacent grooves 3 are all equal in the same manner.
In addition, the inner surface of the groove 3 on the shoe sole 1 side is the same height as the tread portion 5 with respect to the thickness direction of the shoe sole 1.

複数の凸部2は、横断面が略二等辺三角形であり、それぞれの略二等辺三角形は合同で、略二等辺三角形の足幅方向高さは隣接する溝3の間隔と等しく、溝3のうち隣接する二つの溝3間に一列で、しかも略二等辺三角形の底辺を足長方向に平行で足長方向に隣接する凸部2同士を所定間隔をあけて互い違いにするように配列されている。すなわち、足幅方向を左右方向としたとき、底辺に対して頂角が右側にある凸部2に対し、その凸部2のつま先側に隣接する凸部2は、底辺に対して頂角が左側にある凸部2である。その次につま先側に隣接する凸部2は、底辺に対して頂角が右側にある凸部2である。
ここで、所定間隔とは、溝3の幅と略等しい。
The plurality of convex portions 2 are substantially isosceles triangles in cross section, and the substantially isosceles triangles are congruent, and the foot width direction height of the approximately isosceles triangle is equal to the interval between adjacent grooves 3. Among the two adjacent grooves 3, the bases of the isosceles triangles are arranged in parallel so that the convex portions 2 that are parallel to the foot length direction and adjacent to each other in the foot length direction are staggered at a predetermined interval. Yes. That is, when the foot width direction is the left-right direction, the convex part 2 adjacent to the toe side of the convex part 2 has a vertical angle with respect to the base, with respect to the convex part 2 whose apex angle is on the right side with respect to the base. It is the convex part 2 on the left side. Next, the convex part 2 adjacent to the toe side is the convex part 2 with the apex angle on the right side with respect to the base.
Here, the predetermined interval is substantially equal to the width of the groove 3.

この凸部2の配置パターンが、靴底1のつま先側端部から不踏部5との境界線までと、踵側端部から不踏部5との境界線まで繰り返されており、しかも全ての隣接する溝3間において、同様の配列パターンが繰り返されている。
ただし、靴底1の外周端部では、靴底1の輪郭線で凸部2の配置パターンが分断されており、分断された箇所では凸部2は略二等辺三角形とはなっていない。
加えて、足幅方向に溝3を隔て隣接する二つの凸部2における略二等辺三角形の頂角は、溝3に直交する直線上に位置するように配列した。すなわち、略二等辺三角形の頂角の溝3を垂直に隔てた反対側は、足幅方向に隣接する略二等辺三角形の底辺中央となるように配置されている。
The arrangement pattern of this convex part 2 is repeated from the toe side end of the shoe sole 1 to the boundary line with the treadle part 5 and from the heel side end part to the boundary line with the treadle part 5, and all A similar arrangement pattern is repeated between adjacent grooves 3.
However, at the outer peripheral end portion of the shoe sole 1, the arrangement pattern of the convex portions 2 is divided by the outline of the shoe sole 1, and the convex portions 2 are not substantially isosceles triangles at the divided portions.
In addition, the apex angles of the approximately isosceles triangles in the two convex portions 2 adjacent to each other with the groove 3 in the foot width direction are arranged on a straight line orthogonal to the groove 3. That is, the opposite side of the apex-angle groove 3 of the approximately isosceles triangle that is vertically separated is arranged to be the center of the base of the approximately isosceles triangle that is adjacent in the foot width direction.

凸部2の側壁面は、根元部分以外は靴底1に対して垂直である。一方、凸部2の根元部分は、凸部2の側壁面が靴底1に向かって広がっているが、これは靴底1の生産工程において、金型から靴底1を取り出すときに凸部2がちぎれて金型に残ることを防ぐために、金型のエッジを面取りをする手法であり、これは当事者間ではよく知られている(図3参照)。   The side wall surface of the convex portion 2 is perpendicular to the shoe sole 1 except for the root portion. On the other hand, the base portion of the convex portion 2 has a side wall surface of the convex portion 2 that extends toward the shoe sole 1, which is a convex portion when the shoe sole 1 is taken out from the mold in the production process of the shoe sole 1. In order to prevent 2 from being broken and remaining in the mold, the edge of the mold is chamfered, which is well known among the parties (see FIG. 3).

また凸部2は、略二等辺三角形における底辺中央から頂角側に向けてスリット4を形成してなる。
このスリット4の長さは、凸部2の略二等辺三角形の底辺中央と頂角間を結ぶ距離の略1/2、また、スリット4の幅は、溝3の幅の略1/2、スリット4の深さは凸部2の高さと等しい。また、このスリット4は、底辺中央において溝3と連通している。
Moreover, the convex part 2 forms the slit 4 toward the vertex side from the base of the substantially isosceles triangle.
The length of the slit 4 is approximately ½ of the distance connecting the center of the base of the isosceles triangle of the convex portion 2 and the apex angle, and the width of the slit 4 is approximately ½ of the width of the groove 3. The depth of 4 is equal to the height of the convex portion 2. The slit 4 communicates with the groove 3 at the center of the base.

この耐滑性靴は、次に示すようにして耐滑機能を有する。これを図4を参照して説明する。図4において、(a)は図1に示す耐滑性靴の靴底1の踵側に向かって流れる液体7の流れ方を、(b)は図1に示す耐滑性靴の靴底1のつま先側に向かって流れる液体7の流れ方を、(c)は図1に示す耐滑性靴の靴底1の右側端部(図4において右側)に向かって流れる液体7の流れ方を、(d)は図1に示す耐滑性靴の靴底1の左側端部(図4において左側)に向かって流れる液体7の流れ方をそれぞれ示す。   This slip resistant shoe has a slip resistant function as follows. This will be described with reference to FIG. 4, (a) shows how the liquid 7 flows toward the heel side of the sole 1 of the slip resistant shoe shown in FIG. 1, and (b) shows the toe of the sole 1 of the slip resistant shoe shown in FIG. (C) shows the flow of the liquid 7 flowing toward the side, and (c) shows the flow of the liquid 7 flowing toward the right end (right side in FIG. 4) of the sole 1 of the slip resistant shoe shown in FIG. ) Shows how the liquid 7 flows toward the left end (left side in FIG. 4) of the sole 1 of the slip resistant shoe shown in FIG.

靴底1と床面6の間に介在する液体7が、踵側に向かって流れるときには、液体7は溝3内のつま先側から踵側に向かって流れる。隣接する溝3間に一列に互い違いになっている凸部2同士の間隔内にある液体7は、踵側斜め方向に向かって流れ、溝3の流れと合流する(図4(a)参照)。このとき、液体7の流れを妨げる障壁は無いので、円滑に流れる。
つま先側に向かって流れるときは、踵側に向かって流れるときと180°逆であるので、同様に円滑に流れる(図4(b)参照)。
When the liquid 7 interposed between the shoe sole 1 and the floor surface 6 flows toward the heel side, the liquid 7 flows from the toe side in the groove 3 toward the heel side. The liquid 7 in the space between the convex portions 2 that are alternately arranged in a row between the adjacent grooves 3 flows toward the heel side oblique direction and merges with the flow of the grooves 3 (see FIG. 4A). . At this time, since there is no barrier that obstructs the flow of the liquid 7, it flows smoothly.
When it flows toward the toe side, it is 180 ° opposite to when it flows toward the heel side, and therefore flows smoothly in the same manner (see FIG. 4B).

一方、靴底1と床面6の間に介在する液体7が右側端部に向かって流れるとき、溝3内の液体7はつま先側端部と踵側端部から靴底1外へ排出される。隣接する溝3間に一列に互い違いになっている凸部2同士の間隔内にある液体7は、その空間の右側に連通する溝3へ流れる(図4(c)参照)。このときも同様に、液体7の流れを妨げる障壁は無いので、円滑に流れる。
左側端部に向かって流れるときは、右側端部に向かって流れるときと180°逆であるので、同様に円滑に流れる(図4(d)参照)。
このように、略二等辺三角形の凸部2を、所定間隔をあけて互い違いに配置しているので、排水性において方向依存性が無い。すなわち、耐滑性に方向依存性が無い。
On the other hand, when the liquid 7 interposed between the shoe sole 1 and the floor surface 6 flows toward the right end portion, the liquid 7 in the groove 3 is discharged out of the shoe sole 1 from the toe side end portion and the heel side end portion. The The liquid 7 within the interval between the convex portions 2 that are alternately arranged in a row between the adjacent grooves 3 flows to the groove 3 that communicates with the right side of the space (see FIG. 4C). Similarly, at this time, since there is no barrier that hinders the flow of the liquid 7, it flows smoothly.
When flowing toward the left end, it is 180 ° opposite to when flowing toward the right end, and thus flows smoothly in the same manner (see FIG. 4D).
Thus, since the convex part 2 of a substantially isosceles triangle is arrange | positioned alternately at predetermined intervals, there is no direction dependence in drainage. That is, the slip resistance has no direction dependency.

また、不踏部5を設けていることにより、つま先部に介在する液体7を踵側端面まで排出する必要がない。すなわち、排出までの液体7の移動距離が短くなるので、素早く排出できる。   Further, since the tread portion 5 is provided, it is not necessary to discharge the liquid 7 interposed in the toe portion to the heel side end surface. That is, since the moving distance of the liquid 7 until discharge becomes short, it can discharge quickly.

また、ユーザが当該靴を履いて歩行すると、荷重のかかった凸部2が倒れるように変形する。これを図5を参照して説明する。図5において、(a)は耐滑性靴の凸部2にスリット4が入っていない場合の変形時の様子を示す拡大断面図であり、(b)は耐滑性靴の凸部2にスリット4が入った場合、すなわち、図1に示す耐滑性靴の凸部2の変形時の様子を示す拡大断面図である。
前述したように、倒れた凸部2の接地面と床面6との間に液体7が入り込むことが滑りの原因となる(図5(a)参照)が、このとき、凸部2にスリット4が設けられた場合には、スリット4を境に、凸部2の片側が倒れたとしても、もう片側が倒れないため床面6とのグリップ力を保持できる(図5(b)参照)。
Further, when the user walks while wearing the shoes, the convex portion 2 to which the load is applied is deformed so as to fall down. This will be described with reference to FIG. In FIG. 5, (a) is an enlarged sectional view showing a state at the time of deformation when the convex portion 2 of the slip resistant shoe does not have the slit 4, and (b) is a slit 4 in the convex portion 2 of the slip resistant shoe. It is an expanded sectional view which shows the mode at the time of a deformation | transformation of the convex part 2 of the slip resistant shoes shown in FIG.
As described above, the liquid 7 enters between the ground surface 6 and the floor surface 6 of the convex part 2 that has fallen, causing a slip (see FIG. 5A). When 4 is provided, even if one side of the convex portion 2 falls down with the slit 4 as a boundary, the other side does not fall down, so that the grip force with the floor surface 6 can be maintained (see FIG. 5B). .

また、スリット4があることで、凸部2の接地面に付着した液体7は、直接溝3に流れ込むだけではなく、スリット4にも流れ込む場合があるが、スリット4の中の液体7は、スリット4と連通されている溝3より靴底1外へ排出されるので、スリット4内に滑りの原因となる液体が留まることはない。。
それに加え、不踏部5よりつま先側と踵側では、凸部2の略二等辺三角形の向きが異なっているため、これにより例えば踵側の凸部2に倒れやすい力が加わったとしてもつま先側の凸部2が倒れにくく、滑りにくい。
In addition, the presence of the slit 4 causes the liquid 7 attached to the ground contact surface of the convex portion 2 to flow not only directly into the groove 3 but also into the slit 4, but the liquid 7 in the slit 4 Since the liquid is discharged out of the shoe sole 1 through the groove 3 communicating with the slit 4, the liquid causing the slip does not remain in the slit 4. .
In addition, since the direction of the substantially isosceles triangle of the convex portion 2 is different between the toe side and the heel side from the non-stepped portion 5, it is assumed that a force that tends to fall, for example, is applied to the convex portion 2 on the heel side. The convex part 2 on the side is difficult to fall down and slip easily.

(第二実施形態)
次に、図2、図6及び図7を参照して、本発明の第二実施形態に係る耐滑性靴を説明する。図2は、図6に示す靴底1の凸部2に関する拡大斜視図である。図6は、本発明の第二実施形態に係る耐滑性靴の靴底1を示す平面図である。図7は液体の流れ方向を示すもので、(a)は図6に示す耐滑性靴の靴底1の踵側に向かって流れる液体7の流れ方を、(b)は図6に示す耐滑性靴の靴底1のつま先側に向かって流れる液体7の流れ方を、(c)は図6に示す耐滑性靴の靴底1の右側端部に向かって流れる液体7の流れ方を、(d)は図6に示す耐滑性靴の靴底1の左側端部に向かって流れる液体7の流れ方をそれぞれ示す。
(Second embodiment)
Next, with reference to FIG.2, FIG6 and FIG.7, the slip resistant shoes which concern on 2nd embodiment of this invention are demonstrated. FIG. 2 is an enlarged perspective view of the convex portion 2 of the shoe sole 1 shown in FIG. FIG. 6 is a plan view showing the sole 1 of the slip-resistant shoe according to the second embodiment of the present invention. FIG. 7 shows the flow direction of the liquid. (A) shows the flow of the liquid 7 flowing toward the heel side of the sole 1 of the slip resistant shoe shown in FIG. 6, and (b) shows the slip resistant shown in FIG. (C) shows the flow of the liquid 7 flowing toward the right end of the sole 1 of the slip resistant shoe shown in FIG. (D) shows how the liquid 7 flows toward the left end of the sole 1 of the slip resistant shoe shown in FIG.

第一実施形態と不踏部5の位置と凸部2との境界線の角度は同じである。また、溝3と凸部2の位置関係は第一実施形態と同じである。しかし靴底1と、溝3や凸部2の位置関係は、第一実施形態とは異なり、不踏部5よりつま先側と、不踏部5より踵側のそれぞれで第一実施形態の配列パターンを90°回転させたものとなっている。   The angle of the boundary line between the first embodiment, the position of the tread portion 5 and the convex portion 2 is the same. The positional relationship between the groove 3 and the convex portion 2 is the same as that in the first embodiment. However, the positional relationship between the shoe sole 1 and the groove 3 or the convex portion 2 is different from that of the first embodiment, and the arrangement of the first embodiment on the toe side from the non-stepping portion 5 and on the heel side from the non-stepping portion 5. The pattern is rotated 90 °.

これによる、第一実施形態との効果の違いは次の通りである。
液体7が排出される際、本実施形態に係る靴では、靴底1の足幅方向端部から靴底1外へ速やかに排出される。すなわち、足長方向に平行に延びる溝3を通じて踵側端部より排出しなければならない第一実施形態の耐滑性靴に比べ、本実施形態に係る靴では、足長方向のどの位置に存在する液体7でも、足長方向よりも移動距離の短い足幅方向から靴底1外へ排出されるので、第一実施形態の耐滑性靴より素早く排水できる。すなわち、より耐滑性が優れる。
The difference in effect from the first embodiment is as follows.
When the liquid 7 is discharged, in the shoe according to the present embodiment, the liquid 7 is quickly discharged from the end in the foot width direction of the shoe sole 1 to the outside of the shoe sole 1. That is, in the shoe according to the present embodiment, the shoe according to the present embodiment is present at any position in the foot length direction as compared with the slip resistant shoe of the first embodiment that must be discharged from the heel side end portion through the groove 3 extending parallel to the foot length direction. The liquid 7 can also be drained more quickly than the slip resistant shoes of the first embodiment because the liquid 7 is discharged out of the shoe sole 1 from the width direction of the foot, which is shorter than the length direction of the foot. That is, the slip resistance is more excellent.

また、凸部2の配列パターンは第一実施形態の配列パターンを90°回転させただけなので、第一実施形態と同様、排水性に方向依存性が無い。すなわち、耐滑性に方向依存性が無い(図7参照)。   Moreover, since the arrangement | sequence pattern of the convex part 2 only rotated the arrangement pattern of 1st embodiment 90 degrees, there is no direction dependence in drainage property similarly to 1st embodiment. That is, the slip resistance has no direction dependency (see FIG. 7).

なお、スリット4の効果や、不踏部5よりつま先側と踵側で凸部2の略二等辺三角形の向きが傾いていることの効果は第一実施形態に等しい。   Note that the effect of the slit 4 and the effect that the direction of the substantially isosceles triangle of the convex portion 2 is inclined on the toe side and the heel side from the tread portion 5 are equal to those of the first embodiment.

(第三実施形態)
次に、図2及び図8を参照して、本発明の第三実施形態に係る耐滑性シート8を説明する。図2は、図8に示す耐滑性シート8の凸部2に関する拡大斜視図である。図8は、本発明の第三実施形態に係る耐滑性シート8を示す平面図である。
この耐滑性シート8は、水、油、溶剤、液状石鹸等の液体7が付着して滑りやすい状態にある床面6に対して滑り難くした耐滑性シート8に関するもので、第一実施形態及び第二実施形態に係る靴の靴底1における、溝3や凸部2の配列パターンは同じである。ただし、靴底1とは違い、不踏部5は設けられていない。
(Third embodiment)
Next, with reference to FIG.2 and FIG.8, the slip resistant sheet 8 which concerns on 3rd embodiment of this invention is demonstrated. FIG. 2 is an enlarged perspective view of the convex portion 2 of the slip resistant sheet 8 shown in FIG. FIG. 8 is a plan view showing the slip resistant sheet 8 according to the third embodiment of the present invention.
This slip-resistant sheet 8 relates to the slip-resistant sheet 8 that is difficult to slide with respect to the floor surface 6 that is in a slippery state with a liquid 7 such as water, oil, solvent, liquid soap, etc. attached thereto. The arrangement pattern of the groove | channel 3 and the convex part 2 in the shoe sole 1 of the shoe which concerns on 2nd embodiment is the same. However, unlike the shoe sole 1, the tread portion 5 is not provided.

この配列パターンが耐滑性シート8の表裏共に施されていることにより、床面6と耐滑性シート8間の、耐滑性シート8と靴間の耐滑性をそれぞれ保っている。すなわち、床面6に耐滑性シート8を敷いておけば、既存の靴を使用しても耐滑性を得ることができる。また、他の実施形態に係る靴と同様に、略二等辺三角形の凸部2を所定間隔をあけて互い違いに配置しているため、排水性、すなわち耐滑性に方向依存性が無い。なお、この配列パターンを耐滑性シート8の表裏のいずれか一方に施すだけでも耐滑性効果は得られる。   Since this arrangement pattern is applied to both the front and back surfaces of the slip resistant sheet 8, the slip resistance between the floor surface 6 and the slip resistant sheet 8 and between the slip resistant sheet 8 and the shoes is maintained. That is, if the slip-resistant sheet 8 is laid on the floor surface 6, slip resistance can be obtained even if existing shoes are used. Moreover, since the isosceles triangular convex portions 2 are alternately arranged at a predetermined interval as in the shoes according to other embodiments, the drainage property, that is, the slip resistance has no direction dependency. Note that the slip resistance effect can be obtained only by applying this arrangement pattern to either the front or back of the slip resistant sheet 8.

なお、第一乃至第三実施形態に係る耐滑性靴や耐滑性シート8の凸部2の配列は、溝3に直交する一直線上において、凸部2の略二等辺三角形の頂角が全て同一の方向を向いているが、これに限られるものではなく、この直線上に並ぶ頂角は溝3を隔てて向かい合っていてもよい。
あるいは、複数の凸部2の略二等辺三角形の頂角を、溝3に直交する直線上に位置しないように配列することもできる。
In addition, as for the arrangement | sequence of the convex part 2 of the slip resistant shoes which concerns on 1st thru | or 3rd embodiment, or the slip resistant sheet 8, the vertex angle of the substantially isosceles triangle of the convex part 2 is all the same on the straight line orthogonal to the groove | channel 3. However, the present invention is not limited to this, and the apex angles aligned on this straight line may face each other across the groove 3.
Alternatively, the apex angles of the substantially isosceles triangles of the plurality of convex portions 2 can be arranged so as not to be positioned on a straight line orthogonal to the groove 3.
