Abstract
Description
本発明は床面が乾燥状態、水で濡れた状態、油が付着した状態であっても、また歩行方向を問わず安定した歩行ができる耐滑靴底及びその靴底成形金型に関するものである。 The present invention relates to a slip-resistant shoe sole capable of stable walking regardless of the walking direction and a mold for molding the shoe sole, even when the floor surface is in a dry state, wet with water, or with oil attached. .
従来、耐滑靴底及びその靴底成形金型に関して、耐滑性を高めるために様々な提案がなされている。 Conventionally, various proposals have been made to improve the slip resistance with respect to the slip resistant sole and the mold for molding the sole.
例えば、靴底の接地面の底意匠パターンに関して、靴底接地底は54〜62(JIS−A 、 20℃)の硬度を有するゴム、ポリ塩化ビニル、ポリウレタンからなり、最薄部の厚さが3〜8mmで、靴底接地部には、多角形、円形などのブロック意匠パターンを有するように形成し、さらにブロック意匠のパターンは、意匠高さが1〜7mm、意匠勾配が0〜3度、最小寸法が2〜8mmで、トップには凹凸模様がなく、フラットであることにより、床面上の水膜や油膜を切ることができ、ブロック意匠の変形を抑えることができる耐滑靴底が開示されている。(特許文献1) For example, with respect to the bottom design pattern of the contact surface of the shoe sole, the contact surface of the shoe sole is made of rubber having a hardness of 54 to 62 (JIS-A, 20 ° C.), polyvinyl chloride, and polyurethane, and the thickness of the thinnest part is 3 to 8 mm, and the shoe sole grounding part is formed so as to have a block design pattern such as a polygon or a circle. The block design pattern has a design height of 1 to 7 mm and a design gradient of 0 to 3 degrees. , The minimum dimension is 2-8mm, and the top has no uneven pattern, and by being flat, it is possible to cut the water film and oil film on the floor surface, and the anti-skid shoe sole that can suppress the deformation of the block design It is disclosed. (Patent Document 1)
また、靴底の接地面側に複数の接地凸部を長さ方向に所定間隔を設けて形成し、その各接地凸部はV字形状の横断面を有し、前記靴底との付け根部位に傾斜補強部が形成され、20℃におけるJIS−A硬度が45〜80度の弾性重合体によって形成されている耐滑靴底が開示されている。(特許文献2) Further, a plurality of grounding convex portions are formed on the grounding surface side of the shoe sole at predetermined intervals in the length direction, each grounding convex portion has a V-shaped cross section, and a base portion with the shoe sole An anti-skid shoe sole is disclosed in which an inclined reinforcing portion is formed and an elastic polymer having a JIS-A hardness of 45 to 80 degrees at 20 ° C. is disclosed. (Patent Document 2)
さらに、靴底接地部は靴底外周に流体を密閉する周壁がなく靴底に介在する流体を靴底外へ排出する縦横溝を有するヘリンボーンのブロック意匠で、ヘリンボーンの凸部幅が3〜5mm、凹部幅が2〜5mm、意匠深さが1.5〜3mmである防滑靴底も開示されている。(特許文献3) Furthermore, the sole contact portion is a herringbone block design that has no circumferential wall that seals the fluid on the outer periphery of the sole and has vertical and horizontal grooves for discharging the fluid interposed in the sole to the outside of the sole, and the convex width of the herringbone is 3 to 5 mm. An anti-slip shoe sole having a recess width of 2 to 5 mm and a design depth of 1.5 to 3 mm is also disclosed. (Patent Document 3)
一方、靴底成形金型においては、靴底接地部の凹凸パターンとして、凸部である接地ブロックでその接地面との側面とが略直交する接地ブロックを複数有する靴底を射出成形するための金型であって、金型本体と、これに嵌合する少なくとも一つの嵌合部材とで構成され、前記接地ブロックの前記接地面と前記側面とで形成される角の全てを、互いに略直交する前記金型本体と前記嵌合部材との組み合わせ面若しくは前記嵌合部材同士の組み合わせ面の隅部、またはこの組み合わせの隅部に連通する隅部であって同一嵌合部材の略直交する面、または金型本体の略直交する面とで形成された隅部で成形し、且つ前記接地ブロックのそれぞれについては、前記接地面と前記接地面とで形成される角部の少なくとも一部が、互いに略直交する前記金型本体と前記嵌合部材との組み合わせ面もしくは前記嵌合部材同士の組み合わせ面の隅部で成形されるように構成されている靴底射出成形用金型が開示されている。(特許文献4) On the other hand, in the sole molding mold, as a concavo-convex pattern of the shoe sole grounding portion, a shoe sole having a plurality of grounding blocks that are substantially perpendicular to the side surface of the grounding surface of the grounding block that is a convex portion is formed by injection molding. A mold comprising a mold body and at least one fitting member fitted to the mold body, and all corners formed by the grounding surface and the side surface of the grounding block are substantially orthogonal to each other. The corner of the combined surface of the mold body and the fitting member, the combined surface of the fitting members, or the corner communicating with the corner of the combination and substantially perpendicular to the same fitting member Or at each corner formed by a substantially orthogonal surface of the mold body, and for each of the grounding blocks, at least a part of the corner formed by the grounding surface and the grounding surface, Said substantially orthogonal to each other Sole injection mold that is configured is disclosed to be formed at the corners of the coupling side or a combination surface of the fitting member to each other between the mold body and the fitting member. (Patent Document 4)
一般に、耐滑靴底のブロック意匠はそのブロック意匠の壁に直交する方向への滑りについてはグリップ力を発揮し滑りが効果的に防止されるが、ブロック意匠の壁の斜め方向の滑りについては壁に直交方向する向きに対して抵抗力が分散して減少するため、床面に対するブロック意匠の壁の角縁による引っ掛けや、また水や油の膜を切断する力が弱くなり、耐滑性が発揮されない傾向がある。そのため、靴底の耐滑性は滑り方向に対してそのブロック意匠の突起の壁向きによって大きく左右されるため、特にブロック意匠の形状、配置及び配列を考慮しなければならない。 In general, the block design of the anti-skid shoe sole exhibits a gripping force for sliding in the direction perpendicular to the wall of the block design and effectively prevents the sliding, but the sliding of the block design wall in the diagonal direction is a wall. Since the resistance force is dispersed and reduced in the direction perpendicular to the surface, the hooking force by the corner edge of the block design wall against the floor surface and the force to cut the water or oil film are weakened and the slip resistance is demonstrated. There is a tendency not to be. Therefore, since the slip resistance of the shoe sole is greatly influenced by the wall direction of the projection of the block design with respect to the sliding direction, the shape, arrangement and arrangement of the block design must be taken into consideration.
特許文献1での耐滑靴底は、前記防滑機能を発揮させるためにブロック意匠の壁を靴底の爪先方向に対して斜め方向や直交する横幅方向に配置されているが、これら個々の突起自体の形状、個数及びその向きによっては防滑機能が低下し、またブロック意匠が歩行動作を考慮されて配置されていないために、靴底の防滑性を満足させることには難点がある。また、耐滑靴底は床面の状態、即ち床面が水で濡れた状態、油分を付着した状態や乾燥状態とではグリップ性が極端に異なり、安定した耐滑機能が発揮されずに満足させることはできなかった。そして、このような耐滑靴底はブロック意匠が靴底接地面に散在された構成であるため、ブロック意匠とブロック意匠との間にゴミ、小石などの固形物がバラバラに挟まりがちであり、それら固形物を除去するには個々の除去作業となり接地面を掃除するのに不便が生じていた。 In the anti-skid shoe sole in Patent Document 1, the wall of the block design is arranged in an oblique direction or a transverse width direction perpendicular to the toe direction of the shoe sole in order to exhibit the anti-slip function. Depending on the shape, number and orientation of the shoe, the anti-slip function is lowered, and the block design is not arranged in consideration of the walking motion, so that there is a difficulty in satisfying the anti-slip property of the shoe sole. In addition, the slip-resistant shoe sole must satisfy the condition that the grip surface is extremely different from the floor surface, that is, the floor surface is wet with water, the oil is attached, or the dry state, without exhibiting a stable anti-slip function. I couldn't. And since such a slip-resistant shoe sole has a configuration in which block designs are scattered on the shoe sole grounding surface, solids such as dust and pebbles tend to be caught between the block design and the block design. In order to remove the solid matter, it was an individual removal work, and inconvenience occurred in cleaning the ground plane.
また、特許文献2での耐滑性靴底においては、前記各接地凸部が爪先方向に向いたV字形状の横断面を有しているためV字形状の壁の直交方向、即ち靴底の斜め前方方向に対しては耐滑性が発揮されるが、前記耐滑靴底と同様な理由により前後方向及び横幅方向への滑りについては耐滑性が万全ではなく改良の余地があった。 Further, in the slip resistant shoe sole disclosed in Patent Document 2, each of the ground contact protrusions has a V-shaped cross section facing the toe direction, so that it is orthogonal to the V-shaped wall, that is, the sole of the shoe sole. Although slip resistance is exhibited in the diagonally forward direction, the slip resistance in the front-rear direction and the lateral width direction is not perfect for the same reason as the slip-resistant shoe sole, and there is room for improvement.
さらに、特許文献3の防滑靴底はブロックがヘリンボーン意匠であるが、この意匠の靴底も前記と同様の理由により前後方向及び横幅方向への滑りについて、ブロック意匠の壁の向きが対応しておらず、防滑性が満足できるものでなかった。 Furthermore, the anti-slip shoe sole of Patent Document 3 has a herringbone design on the block, but the shoe sole of this design also corresponds to the direction of the wall of the block design for sliding in the front-rear direction and the lateral direction for the same reason as described above. The slip resistance was not satisfactory.
そして、靴底射出成形用金型においては、多様なブロック突起を成形するのに数種類の嵌合部材及び多数の嵌合部材が必要であると同時にそれらの嵌合部材の組み合わせ構造が複雑となり、金型を製作するのにコストが高額になるきらいがあった。さらには、靴底接地部の凹凸のパターンは通常嵌合部材を組み易くするために長方体、立方体などの矩形形状に限られるため、上記耐滑靴底と同様に防滑機能を有するには個々の突起成形凹部の向きを考慮し配置、配列しなければならない難点があった。 And in the mold for shoe sole injection molding, several types of fitting members and a large number of fitting members are required to form various block protrusions, and at the same time, the combined structure of these fitting members becomes complicated. There was a need to make the mold expensive. Furthermore, since the concave / convex pattern of the shoe ground contact portion is usually limited to a rectangular shape such as a rectangular shape or a cube in order to make it easy to assemble the fitting member, However, there is a difficulty in arranging and arranging in consideration of the direction of the protrusion forming concave portion.
そこで、本発明の耐滑靴底は、床面が乾燥状態、水で濡れた状態、油分が付着した状態でも良好な耐滑性を示し、また歩行動作を考慮して耐滑性を高め、安定した防滑機能を備えた靴底及びその靴底成形金型を提供することを課題としている。 Therefore, the anti-skid shoe sole of the present invention exhibits good slip resistance even when the floor surface is dry, wet with water, or with oil attached, and has improved slip resistance in consideration of walking motion, thus providing stable anti-slip. An object is to provide a shoe sole having a function and a mold for molding the shoe sole.
本発明の耐滑靴底は接地面側に独立したブロック突起を複数備えたゴム状弾性体からなる耐滑靴底において、該各ブロック突起の接地面を平滑とするとともにブロック突起の立ち上がり壁を接地面に対して直角とした略三日月形状突起からなり、該三日月形状突起の曲面壁を靴底の長手方向に向けて所定間隔に配列し、該三日月状突起の突起幅をその中央部より先端の端部に向けて漸次幅を狭く形成すると共に、該先端の端部の立ち上がり壁を長手方向に沿った平面状とした。これにより、本発明の耐滑靴底は略三日月形状突起の立ち上がり壁が長手方向に対し曲面壁であるのでいづれかの部分が前後斜め方向の滑りに対して直交し、かつ端部が平面壁であるので横幅方向の滑りに対しても直交して形成される。 The anti-skid shoe sole of the present invention is a anti-skid shoe sole made of a rubber-like elastic body having a plurality of independent block projections on the ground surface side. The ground surface of each block projection is smoothed and the rising wall of the block projection is grounded. The crescent-shaped projections are arranged at predetermined intervals in the longitudinal direction of the shoe sole, and the projection width of the crescent-shaped projections is extended from the center to the end of the tip. The width was gradually narrowed toward the portion, and the rising wall at the end of the tip was formed in a planar shape along the longitudinal direction. As a result, the anti-skid shoe sole of the present invention has a substantially crescent-shaped protrusion whose rising wall is a curved wall with respect to the longitudinal direction, so that any part is orthogonal to the sliding in the front-rear direction and the end is a flat wall. Therefore, it is also formed orthogonal to the lateral width slip.
前記略三日月形状突起はその素材を硬度45〜60(JIS-A)を有するゴム、ポリ塩化ビニル、ポリウレタンとし、ブロック突起の高さを1.5〜4.5mmとし、また中央部での突起幅を3〜9mmとし、横幅方向の長さを20〜35mmとした。これにより、本発明の耐滑靴底は略三日月形状突起同士の間隔を狭くして長手方向に多数隣接して配列でき、また横幅方向に対しては3列配列できるので、靴底全体に対して突起接地面積の占有率を高く確保することができる。尚、前記略三日月形状突起は靴底接地面の外周付近や不踏部付近などでの配置によっては該突起の一部が削除されたり、また変形した形状となる。 The substantially crescent shaped protrusions are made of rubber having a hardness of 45 to 60 (JIS-A), polyvinyl chloride, and polyurethane, the height of the block protrusion is 1.5 to 4.5 mm, and the protrusion at the center portion. The width was 3 to 9 mm, and the length in the width direction was 20 to 35 mm. Accordingly, the anti-skid shoe sole of the present invention can be arranged adjacent to each other in the longitudinal direction by narrowing the interval between the substantially crescent shaped projections, and can be arranged in three rows in the lateral direction, It is possible to ensure a high occupation ratio of the protrusion grounding area. The substantially crescent-shaped protrusions may have a shape in which a part of the protrusions are deleted or deformed depending on the arrangement near the outer periphery of the shoe ground contact surface or near the tread.
また、前記略三日月状突起は靴底縦中央にその突起の曲面内壁を爪先方向に向けて複数配置し、またその靴底縦中央に配置した略三日月形状突起の両側にはそれに並行して曲面内壁を踵方向に逆向きに向けた略三日月形状突起を複数配置し、これら横幅方向に隣接した前記略三日月形状突起同士が連続した略波状になるように配列した。これによって、本耐滑靴底は曲面内壁を異方向へ配置した略三日月形状突起を備えたことにより、前後、斜め、横歩行に対応すると共に停止、後退などの歩行動作についてもグリップ性が作用し、さらに安定した歩行が行える。 The substantially crescent-shaped projections are arranged in the shoe center in the longitudinal center with a plurality of curved inner walls facing the toe direction, and on both sides of the substantially crescent-shaped projection arranged in the shoe center in the longitudinal center, A plurality of substantially crescent-shaped protrusions having the inner wall directed in the opposite direction to the heel direction were arranged, and the substantially crescent-shaped protrusions adjacent in the width direction were arranged so as to have a continuous wave shape. As a result, the anti-skid shoe sole has a substantially crescent-shaped protrusion with the curved inner wall arranged in a different direction. In addition, more stable walking can be performed.
そして、前記耐滑靴底はその接地面と反対側の上面側に、外周下縁を突出させ下面側に窪みを設けたミッドソールを備え、該耐滑靴底のベース面を前記ミッドソールの外周下縁と同じ高さに合わせて耐滑靴底を該ミッドソールの窪みに埋設し接着させた。これによって、本耐滑靴底は本底面が効率的に床面に接することによる耐滑性の向上と共に靴底接地面側に挟まったゴミなどの固形物をベース面を通じて靴底外に排出できる。 The anti-skid shoe sole has a midsole on the upper surface side opposite to the ground contact surface, and has a midsole with an outer peripheral lower edge protruding and a recess formed on the lower surface side. A slip-resistant shoe sole was embedded in the recess of the midsole and adhered to the same height as the edge. As a result, the anti-skid shoe sole can improve the anti-slip property due to the bottom surface efficiently contacting the floor surface, and can discharge solid matter such as dust sandwiched between the shoe sole grounding surface and the outside of the shoe sole through the base surface.
上記耐滑靴底はそのブロック突起の接地面の平滑度(凹凸の幅)を十点平均粗さ:Rz=1〜10μmとした。これにより、本耐滑靴底は該接地面と床面との密着性が増加し、防滑性が向上する。 The anti-skid shoe sole has a ten-point average roughness: Rz = 1 to 10 μm as the smoothness (uneven width) of the ground contact surface of the block protrusion. As a result, the anti-skid shoe sole increases the adhesion between the ground contact surface and the floor surface, and the anti-slip property is improved.
次に、靴底接地面に独立した複数のブロック突起を有する靴底を成形するための靴底成形金型においては、金型本体に設けた中空部の下部に上面に成形面を有したベース金型を嵌合して取付け、また該中空部の上部に上蓋を置いて該ベース金型と上蓋と間に靴底成形空隙を形成し、前記ベース金型の成形面には靴底の横幅方向に波形状の山部及び谷部からその中間部にかけて幅広に形成した複数の波状嵌合突起と長手方向にほぼ直線形状にした複数の線状嵌合突起とを前記波形嵌合突起の山部と谷部との中間部で交差させるとともに両嵌合突起の上部を成形面より突出させ、当該両嵌合突起の壁面を前記成形面に直立するよう嵌合して取り付けて、該ベース金型の成形面側に複数のブロック突起成形用の略三日月状の凹部を形成した。 Next, in a shoe molding mold for molding a shoe sole having a plurality of independent block protrusions on the shoe ground contact surface, a base having a molding surface on the upper surface at the lower part of the hollow portion provided in the mold body A mold is fitted and attached, and an upper lid is placed on the upper part of the hollow portion to form a sole forming gap between the base mold and the upper lid, and the width of the sole is formed on the molding surface of the base mold. A plurality of wavy fitting protrusions formed in a wide shape from a wave-shaped crest and trough to an intermediate portion thereof and a plurality of linear fitting protrusions that are substantially linear in the longitudinal direction The base metal and the trough are made to intersect with each other and the upper portions of both fitting projections protrude from the molding surface, and the wall surfaces of both fitting projections are fitted and attached so as to stand upright on the molding surface. A plurality of substantially crescent-shaped concave portions for forming the block protrusions were formed on the molding surface side of the mold.
前記複数のブロック突起成形用の略三日月状の凹部は該ベース金型と該ベース金型の接地面に前記両嵌合突起が嵌合し組み合わされた構造となる。したがって、本発明の靴底成形金型はその凹部の隅部において空気が嵌合隙間から抜けて溜まらずに靴底成形されるので該突起の角縁をシャープに成形でき、しかも従来より嵌合部材の数、種類を少なくでき、その組み立てが簡易である。 The substantially crescent-shaped recesses for forming the plurality of block protrusions have a structure in which the both fitting protrusions are fitted and combined with the base mold and the ground contact surface of the base mold. Therefore, the shoe mold according to the present invention is formed at the corner of the concave portion without the air leaving the fitting gap and accumulating, so that the corner edge of the protrusion can be formed sharply and moreover fitted than before. The number and type of members can be reduced and the assembly is simple.
また、前記複数のブロック突起成形用の略三日月形状の凹部は、靴底縦中央に略三日月形状の凹部の曲面内壁を爪先方向に向けて配列し、またその靴底縦中央に配列した略三日月形状の凹部の両側にはそれと曲面内壁を逆向きにした踵向きの略三日月形状の凹部を並設した。 Further, the substantially crescent-shaped recesses for forming the plurality of block protrusions are arranged at the center of the shoe sole with the curved inner wall of the recess of the approximately crescent shape facing the toe direction, and the approximately crescent moon arranged at the center of the shoe sole. On both sides of the shape-shaped recess, a substantially crescent-shaped recess facing in the heel direction with the curved inner wall facing in the opposite direction was provided side by side.
さらに、前記複数のブロック突起成形用の略三日月形状の凹部は、靴底前方部においてその全体を不踏中央部を中心に第二指へと内側に向けて配列した。 Further, the plurality of substantially crescent-shaped concave portions for forming the block protrusions are arranged in the front portion of the shoe sole inwardly toward the second finger around the center of the tread.
本発明の耐滑靴底は、靴底接地面に設けた略三日月形状突起の前後の立ち上がり壁を曲面とし、その曲面内壁を靴底の長手方向に向けて配置することでいずれかの部分が滑り方向に対して直交する同時に略三日月形状突起の端部の壁が長手方向に沿った面、即ち横幅方向に対してほぼ直交するように形成されているので、グリップ力F1,F2,F3が効果的に働き、前方、斜め、横幅、後方方向への滑りが防止され安定した歩行がなされる。 The anti-skid shoe sole of the present invention has a rising wall before and after the substantially crescent-shaped protrusion provided on the contact surface of the shoe sole as a curved surface, and the curved inner wall faces the longitudinal direction of the shoe sole so that any portion slips. At the same time, the wall of the end of the substantially crescent shaped projection that is orthogonal to the direction is formed so as to be substantially orthogonal to the surface along the longitudinal direction, that is, the lateral direction, so that the gripping force F1, F2, F3 is effective. It works smoothly and prevents a slip in the forward, oblique, lateral, and backward directions, and makes a stable walk.
また、本発明の略三日月形状突起はその突起幅がその中央部より先端の端部に向けて漸次幅を狭くして突起の弾性を序々に変化させた柔軟弾性を持たせた構造であるため、床面から該略三日月形状突起にかかるグリップ力F1、グリップ力F3によって略三日月形状突起の曲面内壁の角縁に力を集中させ床面に引っ掛かりを起こさせし易くした構成となる。これにより、本発明の耐滑靴底は床面が乾燥状態ではしっかりグリップし、また床面が水で濡れた状態や油が付着した状態では床面上の水膜や油膜を切断し床面の水、油を取り除くことが可能となり、そして勾配がある登り坂、下り坂でも床面をグリップし安定した歩行がなされる。 In addition, the substantially crescent-shaped protrusion of the present invention has a structure in which the protrusion width gradually decreases from the center to the end of the tip, and the elasticity of the protrusion is gradually changed to have a flexible elasticity. The grip force F1 and the grip force F3 applied to the substantially crescent-shaped projection from the floor surface concentrate the force on the corner edge of the curved inner wall of the substantially crescent-shaped projection, thereby easily causing the floor surface to be caught. As a result, the anti-skid shoe sole of the present invention grips firmly when the floor surface is dry, and when the floor surface is wet with water or oil is attached, the water film or oil film on the floor surface is cut to remove the floor surface. Water and oil can be removed, and even on uphill and downhill slopes, the floor can be gripped and walked stably.
さらに、前記略三日月形状突起はその開放部からみてその端部の位置が突起中央部から左右に分岐し手前にズレた位置にあるので、前記突起の中央部にグリップ力F1、F3が作用し一時的に変形が生じたとしても該端部から引っ張り力F4が作用して即座に該突起が弾性回復されるため、突起接地面が床面から離れずに接した状態で突起の倒れが防止され、踏ん張りが効き一層耐滑機能が向上される。 Further, since the position of the end of the substantially crescent-shaped projection as viewed from the open portion branches left and right from the central portion of the projection and is shifted forward, grip forces F1 and F3 act on the central portion of the projection. Even if the deformation occurs temporarily, the pulling force F4 acts on the end and the protrusion is immediately elastically recovered. Therefore, the protrusion is prevented from falling down when the protrusion grounding surface is in contact with the floor without leaving. Thus, the struts are effective and the slip resistance function is further improved.
そして、本発明の耐滑靴底は該耐滑靴底のベース面を前記ミッドソールの外周下縁と同じ高さに合わせて耐滑靴底のベース部をミッドソールの該窪みに埋設しミッドソールを備えた構造になるので、ゴミや小石などの固形物が以前の靴底のように散在することなく、横幅方向の波状の溝や長手方向の直線状の溝に沿って密集するので、ブラシなどでそれら固形物を溝に沿って固形物を取り除くことができ掃除作業が容易である。また、本耐滑靴底はミッドソールによりクッション性が得られる。 The anti-skid shoe sole of the present invention includes a midsole in which the base surface of the anti-skid shoe bottom is set to the same height as the lower peripheral edge of the midsole, and the base portion of the anti-skid shoe sole is embedded in the recess of the midsole. Since solid structures such as trash and pebbles are not scattered like the previous shoe soles, they are concentrated along the wavy grooves in the width direction and the straight grooves in the longitudinal direction. The solid matter can be removed along the groove, and the cleaning operation is easy. In addition, the anti-skid shoe sole is cushioned by a midsole.
一方、靴底成形金型は、ベース金型の成形面に長手方向の線状嵌合突起と横幅方向の波状嵌合突起とを組み合わせ形成して靴底突起成形用凹部の全ての角部を嵌合構造としたため、靴底成形中に空気が嵌合隙間から抜けて隅部や角部に溜まることなく排出されるので靴底突起の角縁がシャープな耐滑靴底が成形される。したがって、本発明の靴底成形金型で成形された靴底は床面での水や油の膜を切断し効果的に滑りを抑制することができる。 On the other hand, the sole molding mold is formed by combining a linear fitting projection in the longitudinal direction and a wavy fitting projection in the width direction on the molding surface of the base mold to form all corners of the depression for molding the sole. Since the fitting structure is adopted, air escapes from the fitting gap during the sole molding and is discharged without accumulating in the corners or corners, so that a slip resistant shoe sole with sharp corner edges is formed. Therefore, the shoe sole formed by the shoe sole molding die of the present invention can cut the water or oil film on the floor surface and effectively suppress the slip.
また靴底成形金型はベース金型の上面に長手方向及び横幅方向の嵌合突起の組みあわせで異方向の略三日月形状突起が同時に形成されるとともに、靴底成形用凹部が簡単な構造で容易に作成できるため、靴底成形金型の製造コストが安価となる。 In addition, the shoe mold has a simple crescent-shaped recess on the upper surface of the base mold and a substantially crescent-shaped protrusion in a different direction at the same time by combining the projections in the longitudinal direction and the width direction. Since it can be made easily, the manufacturing cost of the shoe sole molding die is low.
そして、靴底成形金型は横幅方向と長手方向との嵌合突起が約井形形状に交差した構造であるのでベース金型への取り付け強度が強化され靴底成形金型の耐久性が向上される。 And, since the shoe molding mold has a structure in which the projections in the width direction and the longitudinal direction intersect with each other in the shape of a well, the mounting strength to the base mold is enhanced and the durability of the shoe molding mold is improved.

図1、図 2、図3及び図4に示すように、本発明の耐滑靴底1はベース部2と複数の略三日月形状突起3…を有しており、その略三日月状突起3…はその立ち上がり壁3e…がベース部2の接地面5となす角度αを直角になるように設けられる。略三日月形状突起3…はその曲面壁3a…を靴底の長手方向に向けて所定間隔に配列し、曲面外壁3b(3b’)…の半径を曲面内壁3c(3c’)…の半径より短くするとともに、その曲面外壁3b(3b’)…の半径中心S1を曲面内壁3c(3c’)…の半径中心S2より突起の中央幅w1だけ内側位置にすることにより、突起幅を突起の中央部7から両端の端部8に向けて漸次狭く形成した。 As shown in FIGS. 1, 2, 3, and 4, the anti-skid shoe sole 1 of the present invention has a base portion 2 and a plurality of substantially crescent-shaped projections 3. The rising walls 3e are provided so that an angle α formed with the ground contact surface 5 of the base portion 2 is a right angle. The substantially crescent shaped projections 3 are arranged with their curved walls 3a in the longitudinal direction of the shoe sole at predetermined intervals, and the radius of the curved outer wall 3b (3b ') is shorter than the radius of the curved inner wall 3c (3c'). In addition, by setting the radius center S1 of the curved outer wall 3b (3b ′)... To the position inside the radius center S2 of the curved inner wall 3c (3c ′). 7 was gradually narrowed from 7 toward the ends 8 at both ends.
また、略三日月形状突起3…は、その両端の端部8…の側壁3d(3d’)…を長手方向に沿って平面状に形成される。したがって、本発明の耐滑靴底1は略三日月形状突起3…の曲面壁3aを長手方向に向けて配置することで、歩行において耐滑抑止が前後斜め方向に働き、また横幅方向に対しても滑りが抑制可能となる。これらの略三日月形状突起3…は必要に応じて靴底接地面の全面または爪先部もしくは踵部に部分的に設けてもよい。また、略三日月形状突起3…はその曲面外壁3b(3b’)及び曲面内壁3c(3c’)を円弧状としたが、楕円状、湾曲状でもよい。 The substantially crescent-shaped projections 3 are formed in a planar shape along the longitudinal direction on the side walls 3d (3d ') of the end portions 8 at both ends thereof. Therefore, the anti-skid shoe sole 1 of the present invention has the curved wall 3a of the substantially crescent-shaped projections 3 ... oriented in the longitudinal direction so that anti-slip suppression acts in the diagonal direction in walking and also slips in the lateral width direction. Can be suppressed. These substantially crescent shaped projections 3... May be partially provided on the entire surface of the shoe ground contact surface or on the toe or heel as required. The substantially crescent-shaped projections 3... Have curved outer walls 3b (3b ') and curved inner walls 3c (3c') in an arc shape, but may be elliptical or curved.
前記略三日月形状突起3は、硬度45〜60(JIS−A)を有するゴム、ポリ塩化ビニル、ポリウレタンとし、ブロック突起の高さh1を靴底のベース面より1.5〜4.5mmとし、突起の中央幅w1を3〜9mmとし、横幅方向の長さLを20〜35mmとした。これにより、略三日月形状突起3は、長手方向に対して該略三日月形状突起3同士の間隔を狭くでき、また横幅方向に3列に配列できるので靴底全体に対する突起接地面の比率を高め耐滑機能を向上させることができる。前記略三日月形状突起3は、その端部の突起幅w2を中央幅w1に対して90〜50%、より好ましくは80〜60%が良い。これは、前記端部の突起幅d2が90%以上であれば突起両側部が中央部より柔軟弾性が得られないため引っ掛かり度が低減するきらいがあり、また50%以下にすると突起幅が少なくなり横幅方向に対してグリップ性が減少するきらいがあるからである。また、略三日月形状突起3はその突起の高さh1をその端部の突起幅d2の長さより短くすることで安定性が増加し突起の倒れをより防止できる。 The substantially crescent shaped protrusion 3 is made of rubber, polyvinyl chloride, polyurethane having a hardness of 45-60 (JIS-A), and the height h1 of the block protrusion is 1.5-4.5 mm from the base surface of the shoe sole, The central width w1 of the protrusion was 3 to 9 mm, and the length L in the lateral width direction was 20 to 35 mm. As a result, the substantially crescent-shaped protrusions 3 can narrow the interval between the substantially crescent-shaped protrusions 3 in the longitudinal direction and can be arranged in three rows in the lateral width direction, so that the ratio of the protrusion grounding surface to the entire shoe sole is increased and slip resistance is increased. Function can be improved. The substantially crescent-shaped protrusion 3 has a protrusion width w2 at the end of 90 to 50%, more preferably 80 to 60% with respect to the center width w1. This is because if the protrusion width d2 of the end portion is 90% or more, both sides of the protrusion cannot obtain more flexible elasticity than the center portion, so that the degree of catching is likely to be reduced, and if it is 50% or less, the protrusion width is small. This is because the grip performance tends to decrease in the lateral direction. Further, the substantially crescent-shaped projection 3 has an increased stability by making the height h1 of the projection shorter than the length of the projection width d2 at the end thereof, and the collapse of the projection can be further prevented.
本発明の耐滑靴底の素材は、具体的には天然ゴム、合成ゴム、例えばブタジエン(BR)、スチレンーブタジエンゴム(SBR)、アクリルニトリルーブタジエン(NBR)などのジエン系ゴムやポリウレタン、塩化ビニルなどの合成樹脂をあげることができ、前記素材にゴム配合剤、例えば加硫促進剤、着色剤、可塑剤などを配合して使用する。 Specifically, the material of the anti-skid shoe sole of the present invention is natural rubber, synthetic rubber, for example, diene rubber such as butadiene (BR), styrene-butadiene rubber (SBR), acrylonitrile-butadiene (NBR), polyurethane, chlorinated A synthetic resin such as vinyl can be used, and a rubber compounding agent such as a vulcanization accelerator, a colorant, a plasticizer, and the like are blended with the material.
本発明の耐滑靴底1 はその硬度をJIS−Aに基づいて測定した20℃における硬度を45〜60度としたことにより、より滑りを抑えることができる。尚、前記45度以下であれば突起の変形が大きくなり、前記60度以上になると硬くなりすぎるので踏ん張りが利かなくなり滑りやすくなる傾向がある。 The anti-skid shoe sole 1 of the present invention can suppress slipping more by setting the hardness at 20 ° C. measured according to JIS-A to 45 to 60 degrees. If the angle is 45 degrees or less, the deformation of the protrusion becomes large. If the angle is 60 degrees or more, the protrusion becomes too hard, so that there is a tendency that the struts do not work and it is easy to slip.
本発明の耐滑靴底1は、図2に示すように、その接地面と反対側の上面側に、下面側に外周下縁4aを突設させ窪みを形成したミッドソール4を備え、耐滑靴底のベース面2aをミッドソール4の外周下縁4aと同じ高さに合わせて耐滑靴底1をミッドソール4に埋設して接着させた。該ミッドソール4としてはクッション性を有する発泡ウレタン、発泡EVAなどの素材使用できる。また必要に応じて、耐滑靴底1とミッドソール4との間に硬い素材の中底を挿入してもよい。 As shown in FIG. 2, the anti-skid shoe sole 1 of the present invention includes a midsole 4 having an outer peripheral lower edge 4 a protruding from the lower surface side to form a recess on the upper surface side opposite to the ground contact surface. The base surface 2a of the bottom was adjusted to the same height as the outer peripheral lower edge 4a of the midsole 4, and the anti-skid shoe sole 1 was embedded in the midsole 4 and adhered. As the midsole 4, a material such as foamed urethane or foamed EVA having cushioning properties can be used. If necessary, an insole of a hard material may be inserted between the anti-skid shoe sole 1 and the midsole 4.
そして、前記略三日月状突起3…は靴底縦中央に該突起の曲面内壁3cを靴底の爪先方向に向けて配列し、またその靴底中央に配列した略三日月形状突起3の両端にそれに並行して曲面内壁3c’を踵方向に向けて逆向きにした略三日月形状突起3’…を隣接して配列し、これら前記横幅方向に隣接した略三日月形状突起同士が略波状になるように配置して形成してもよい。 The approximately crescent-shaped projections 3 are arranged at the center of the shoe sole with the curved inner wall 3c facing the toe direction of the shoe sole, and at both ends of the substantially crescent-shaped projection 3 arranged at the center of the shoe sole. In parallel, the substantially crescent-shaped protrusions 3 ', which have the curved inner wall 3c' turned in the reverse direction toward the heel direction, are arranged adjacent to each other so that the substantially crescent-shaped protrusions adjacent in the lateral width direction are substantially wave-like. You may arrange and form.
そして、本発明の耐滑靴底1 は上記通り横幅方向の波状の溝と長手方向に線状の溝とを連結したことにより、波状の溝又は線状の溝を通じて付着したごみを簡単に除去することができ掃除を簡単に行える。 The anti-skid shoe sole 1 according to the present invention connects the wavy grooves in the width direction and the linear grooves in the longitudinal direction as described above, thereby easily removing dust attached through the wavy grooves or the linear grooves. Can be cleaned easily.
さらには、本発明の耐滑靴底は図1に示すように略三日月形状突起3を靴底前方部においては不踏部中央部を中心にその先端を第2指へかけて内側に傾けて配列し、また後方の踵部においてはそのまま踵中心部に沿って配列して、靴底全体において配列の中心軸を略「く」の字状に配列しておけば、その略三日月形状突起3の曲面壁3aの配列がほぼ歩行の際の踵から爪先への重心移動に沿うので、より歩行動作に対応してグリップ力が連動増加して作用し耐滑機能が効果的に発揮される。 Further, as shown in FIG. 1, the anti-skid shoe sole of the present invention is arranged so that the substantially crescent-shaped projection 3 is inclined inwardly with the tip of the center portion of the non-stepped portion centering on the second finger at the front portion of the shoe sole. In addition, if the rear heel part is arranged along the heel center part as it is and the central axis of the arrangement is arranged in a substantially “<” shape over the entire shoe sole, the substantially crescent-shaped projection 3 Since the arrangement of the curved walls 3a substantially follows the movement of the center of gravity from the heel to the tip of the toe during walking, the gripping force increases in response to the walking motion, and the slip resistance function is effectively exhibited.
また、本発明の耐滑靴底1は、前進動作のときは靴底中央に配置された爪先向きの略三日月形状突起3の曲面内壁3c…が床面から作用する踵から爪先へのグリップ力に対応して滑りを抑制し、また停止及び後退動作のときは踵向きの略三日月形状突起3’の曲面内壁3c’…が床面から作用する爪先から踵へのグリップ力に対応して滑りを抑制し、また横方向の歩行動作のときは該三日月形状突起の側壁3d(3d’)…が床面から作用する内側方向へのグリップ力に対応して滑りを抑制する。 Further, the anti-skid shoe sole 1 of the present invention has a curved inner wall 3c of the substantially crescent-shaped projection 3 disposed at the center of the toe for the forward movement, and has a grip force from the heel to the toe that acts from the floor surface. Correspondingly, slippage is suppressed, and when stopping and retreating, the curved inner wall 3c ′ of the substantially crescent-shaped projection 3 ′ facing the heel slips in response to the grip force from the toe to the heel acting from the floor surface. In the case of a lateral walking action, the side wall 3d (3d ') of the crescent shaped protrusion suppresses slipping corresponding to the grip force in the inward direction acting from the floor surface.
本発明の耐滑靴底1はその三日月形状突起の接地面5の平滑度(凹凸の幅)を十点平均粗さ:Rz=1〜10μmとした。この表面粗さは鏡面仕上げ程度で凸凹の高低差が少ないほど床面との密着性がよく滑りが抑制される。 The anti-skid shoe sole 1 of the present invention has a ten-point average roughness: Rz = 1 to 10 μm for the smoothness (width of irregularities) of the ground contact surface 5 of the crescent-shaped projection. The surface roughness is about a mirror finish, and the smaller the unevenness of the unevenness, the better the adhesion with the floor surface and the less the slippage.
次に、前記耐滑靴底1を成形する靴底成形金型20について説明する。本靴底成形金型20は図5、図6及び図7に示すように金型本体21、ベース金型22、上蓋23を備えている。該金型本体21は中空部を有し、該中空部の上部を靴底形状とすると共に該中空部の下部をそれより広い形状にして段差を設けた金属製の板状枠からなり、該中空部の段差部にはその周壁に下方に広がったテーパーが設けられ、そこに上面に靴底形状の成形面を設けたベース金型22をそのテーパーに合わせて下方から該中空部を塞ぐように嵌合収納しネジなどの固定具で取付けられる。また該ベース金型22を取付けた金型本体21はその上面側に靴底形状の窪みが形成され、その窪みに上蓋23が被せられて靴底成形空隙24が形成される。 Next, the shoe sole molding die 20 for molding the anti-skid shoe sole 1 will be described. As shown in FIGS. 5, 6, and 7, the shoe sole molding mold 20 includes a mold body 21, a base mold 22, and an upper lid 23. The mold body 21 has a hollow part, and is formed of a metal plate-like frame having a step shape with the upper part of the hollow part having a shoe sole shape and the lower part of the hollow part having a wider shape, A stepped portion of the hollow portion is provided with a taper extending downward on the peripheral wall thereof, and a base mold 22 provided with a shoe-shaped molding surface on the upper surface thereof is fitted to the taper so as to close the hollow portion from below. Fits in and is attached with a fixture such as a screw. The mold body 21 to which the base mold 22 is attached has a shoe-shaped recess formed on the upper surface thereof, and a top cover 23 is placed on the recess to form a shoe-sole forming cavity 24.
また、ベース金型22はその上部を靴底形状した成形面側には靴底縦中央に波形状の山部を爪先方向に向けた略波形状嵌合突起25…と、また長手方向に線状嵌合突起26…が配列されると共に、該線状嵌合突起26…が前記略波形状嵌合突起25…の波形状の山部25aと谷部25bとの中間部25cに交差し連結するように設けられる。 Further, the base mold 22 has a shoe-shaped upper part on the molding surface side, a substantially wave-shaped fitting projection 25 with a wave-shaped peak portion directed in the toe direction in the longitudinal center of the shoe sole, and a line in the longitudinal direction. Are arranged, and the linear fitting protrusions 26 intersect with and connect to the intermediate portion 25c between the wave-shaped peak portions 25a and valley portions 25b of the substantially wave-shaped fitting protrusions 25. To be provided.
そして、前記波状嵌合突起25…は前記耐滑靴底1の略三日月形状突起3の突起幅がその中央部7から端部8にかけて漸次細幅に成形されるように、その波形状の山部25aと谷部25bとからその中間部25cにかけて嵌合突起幅が漸次肉厚に形成される。また波状嵌合突起25…と線状嵌合突起26…とはその下部をベース金型22に形成された複数の嵌合溝27… に埋め込み、またその上部を成形面22aから突出して直角になるように嵌合して設けられ、成形面22aには複数の整列した略三日月形状の凹部28…が形成される。また、波状嵌合突起25…と線状嵌合突起26…とはその上部先端の角をとり丸みを形成しておけば、成形される耐滑靴底は突起の根元に丸みが形成されるため、略三日月形状突起3が補強される。また、前記波状嵌合突起25…の壁は前記耐滑靴底と同様に円弧に限らず、楕円、湾曲でもよい。 The wavy fitting protrusions 25... Are formed so that the protrusion width of the substantially crescent shaped protrusion 3 of the anti-skid shoe sole 1 is gradually narrowed from the central portion 7 to the end portion 8. The fitting protrusion width is gradually increased from 25a and the valley portion 25b to the intermediate portion 25c. The lower portions of the wavy fitting protrusions 25 and the linear fitting protrusions 26 are embedded in a plurality of fitting grooves 27 formed in the base mold 22, and the upper portions protrude from the molding surface 22a at a right angle. A plurality of aligned substantially crescent shaped recesses 28 are formed on the molding surface 22a. Further, if the wavy fitting protrusions 25 and the linear fitting protrusions 26 are rounded by rounding the corners of the upper ends thereof, the molded anti-skid shoe sole is rounded at the base of the protrusion. The substantially crescent-shaped projection 3 is reinforced. Further, the wall of the wavy fitting protrusions 25 is not limited to an arc like the anti-skid shoe sole, and may be an ellipse or a curve.
さらに、靴底成形金型20は、成形面22aに横幅方向の波状嵌合突起25…を長手方向の線状嵌合突起26…より深く取付けておけば、横幅方向の波状嵌合突起25…が長手方向の線状嵌合突起26…より浅くても長手方向の線状突起26…で止めることができるので取り付け強度をさらに強化することができる。尚、前記嵌合部材のベース金型との嵌合隙間や両嵌合部材と金型本体との嵌合隙が製造上比較的大きく形成された場合は必要に応じて接着剤を塗っておけば作成される耐滑靴底のバリ発生が防止される。 Furthermore, if the shoe-molding mold 20 is mounted on the molding surface 22a with the wavy fitting protrusions 25 in the width direction deeper than the linear fitting protrusions 26 in the longitudinal direction, the wavy fitting protrusions 25 in the width direction. However, even if it is shallower than the linear fitting projections 26 in the longitudinal direction, it can be stopped by the linear projections 26 in the longitudinal direction, so that the mounting strength can be further enhanced. If the fitting gap between the fitting member and the base mold or the fitting gap between the two fitting members and the mold body is relatively large in production, an adhesive may be applied as necessary. In this way, the occurrence of burrs on the anti-skid shoe sole is prevented.
靴底部材組成物はアクリルニトリル−ブダジエンゴムからなるゴム生地に充填剤、加硫剤、加硫促進剤、老化防止剤、着色剤などをロール混練して得る。本耐滑靴底1はこの靴底部材組成物を下記靴底成形金型20に入れ、加硫して耐滑靴底1を作成する。耐滑靴底1の硬度は加硫剤、加硫促進剤、充填剤などを配合して、JIS−A硬度が53度に設定した。本発明で成形される耐滑靴底1は靴胛被にEVA発泡ミッドソールを介して接着して用いた。尚、本実施例では、靴底成形金型は靴底を片足としたが両足を一体に形成してもよい。 The shoe sole member composition is obtained by roll-kneading a filler, a vulcanizing agent, a vulcanization accelerator, an anti-aging agent, a colorant and the like on a rubber fabric made of acrylonitrile-budadiene rubber. The present slip-resistant shoe sole 1 is prepared by putting this shoe sole member composition in the following shoe sole molding mold 20 and vulcanizing it. The hardness of the anti-skid shoe sole 1 was set to 53 degrees JIS-A hardness by blending a vulcanizing agent, a vulcanization accelerator, a filler and the like. The anti-skid shoe sole 1 molded according to the present invention was used by adhering to a shoe hood through an EVA foamed midsole. In the present embodiment, the shoe sole molding die has a shoe sole as one foot, but both feet may be integrally formed.
該略三日月形状突起3は、その曲面外壁3bの半径を20mm、曲面内壁3cの半径を23mmとし、その突起の中央幅w1を6mmとし、突起の長さLを31.5mmとした。また略三日月形状突起3はその突起の先端の端部3d、3dを中央部から漸次幅狭くし端部3dの縦幅w2を4.6mmの形状とした。また耐滑靴底3は略三日月形状突起の高さh1を3mmとし、ベース厚みh2を2.5mmとし、全体の厚みを5.5mmとした。そして、本耐滑靴底は長手方向に配置した略三日月形状突起3と略三日月形状突起3と間の横溝幅を概ね3mmとし、横幅方向に配置した略三日月形状突起3と略三日月形状突起3と間の縦溝幅を3.5mmとした。作成した耐滑靴底は靴サイズ26cmのとき、靴底に略三日月形状突起3を靴底中央長手方向に32列、横幅方向に3列配列できた。 The substantially crescent-shaped projection 3 has a radius of the curved outer wall 3b of 20 mm, a radius of the curved inner wall 3c of 23 mm, a central width w1 of the projection of 6 mm, and a projection length L of 31.5 mm. The substantially crescent-shaped projection 3 has a shape in which the end portions 3d and 3d at the tip of the projection are gradually narrowed from the central portion and the vertical width w2 of the end portion 3d is 4.6 mm. The anti-skid shoe sole 3 had a height of approximately crescent-shaped projections h1 of 3 mm, a base thickness h2 of 2.5 mm, and an overall thickness of 5.5 mm. Then, the anti-skid shoe sole has a lateral groove width between the substantially crescent-shaped projection 3 and the substantially crescent-shaped projection 3 arranged in the longitudinal direction of approximately 3 mm, and the substantially crescent-shaped projection 3 and the substantially crescent-shaped projection 3 arranged in the lateral width direction. The longitudinal groove width between them was set to 3.5 mm. When the produced non-slip shoe sole had a shoe size of 26 cm, approximately crescent-shaped projections 3 could be arranged on the shoe sole in 32 rows in the shoe sole center longitudinal direction and in 3 rows in the lateral width direction.
該靴底成形金型20は、金型本体21に嵌合し取付けられたベース金型22の成形面22eに靴底の横幅方向に複数の波状嵌合突起25…と長手方向に複数の線状嵌合突起26…とを前記波形状の山部25aと谷部25bの中間部25cで交差させ嵌め込むとともに該両嵌合突起の壁を前記成形面22eと直立するよう取り付け、ベース金型22の成形面22eに複数の略三日月状の凹部28…を形成した。 The shoe sole molding die 20 has a plurality of corrugated fitting projections 25 in the lateral width direction of the shoe sole and a plurality of lines in the longitudinal direction on the molding surface 22e of the base mold 22 fitted and attached to the mold body 21. Are fitted so that the wavy peak 25a intersects with the intermediate portion 25c of the trough 25b and the walls of the two mating protrusions are mounted upright with the molding surface 22e. A plurality of substantially crescent-shaped recesses 28 are formed on the 22 molding surfaces 22e.
そして、前記略三日月形状の凹部28…は、その中央部7から先端の端部8に向けて漸次突起幅を狭くした略三日月形状突起3…を成形するために、横幅方向に配列される波状嵌合突起25の突起幅をその波形状の山部または谷部から中間にかけて漸次広げて形成される。そして、略三日月形状の凹部28…はその底面を平滑とし、表面粗さ(凸凹の高さの差)を2μmとした。 The substantially crescent-shaped recesses 28 are wavyly arranged in the lateral width direction so as to form the substantially crescent-shaped projections 3 with gradually narrowing the projection width from the central portion 7 toward the end portion 8 at the tip. The protrusion width of the fitting protrusion 25 is formed to gradually widen from the corrugated peak or valley to the middle. The substantially crescent-shaped recesses 28 have a smooth bottom surface and a surface roughness (difference in height of the unevenness) of 2 μm.
また前記靴底成形金型20は、図6に示すように前記耐滑靴底1を成形するのに靴底成形空隙24の高さを5.5mmとして該耐滑靴底の厚みとし、前記波状嵌合突起25…と線状嵌合突起26…とはベース金型22の成形面22aより3mm突出させて略三日月形状突起の高さd1とし、ベース部の厚みd2を2.5mmとした。また横幅方向の波状嵌合突起25は、概ね突起幅を3mmにして溝幅とし、波状嵌合突起同士の山部での溝間隔を6mmとして略三日月形状突起の中央幅w1とし、また中間部での溝幅を4.6mmとして略三日月形状突起の端部幅w2とした。また、該長手方向の線状嵌合突起22bはその突起幅を3.5mmにして溝幅とし、また不踏部から前方爪先部と踵部とへ沿って屈曲延長させた略「く」の字状の平行2本からなる形状からなり、その2本の線状嵌合突起22の間隔を31.5mmとし、それを略三日月形状突起の長さLとした。これにより、本靴底成形金型は波状嵌合突起25…と線状嵌合突起26…とで囲まれた略三日月形状の凹部28…が形成される。 Further, as shown in FIG. 6, the shoe sole molding die 20 has a shoe sole forming gap 24 having a height of 5.5 mm to form the anti-skid shoe sole 1 so as to have a thickness of the anti-skid shoe sole. The mating protrusions 25 and the linear fitting protrusions 26 are projected 3 mm from the molding surface 22a of the base mold 22 to have a height d1 of a substantially crescent shaped protrusion, and the thickness d2 of the base portion is 2.5 mm. The wavy fitting protrusions 25 in the lateral width direction have a groove width with a protrusion width of approximately 3 mm, a groove interval between the wavy fitting protrusions at a peak of 6 mm, and the center width w1 of the substantially crescent shaped protrusion. The end width w2 of the substantially crescent shaped protrusion was set to 4.6 mm. The linear fitting protrusion 22b in the longitudinal direction has a groove width with a protrusion width of 3.5 mm, and is substantially “ku” that is bent and extended from the tread portion to the front toe portion and the heel portion. Each of the two linear fitting protrusions 22 is 31.5 mm in length, and the length L of the substantially crescent-shaped protrusions. As a result, a substantially crescent-shaped concave portion 28 surrounded by the wavy fitting projections 25 and the linear fitting projections 26 is formed in the present shoe sole molding die.
本発明の靴底成形金型20は略三日月形状の凹部28…の角部ではベース金型22の嵌合溝27に前記略波状嵌合突起25…及び線状嵌合突起26…とが嵌合した隙間から、また靴底外周ではベース金型22と金型本体21との嵌合隙間から空気が抜け、靴底成形される耐滑靴底1はシャープな角縁6を有する突起が成形される。 In the shoe molding die 20 of the present invention, the substantially wavy fitting protrusions 25 and the linear fitting protrusions 26 are fitted in the fitting grooves 27 of the base mold 22 at the corners of the substantially crescent-shaped recesses 28. Air escapes from the fitted gap and from the fitting gap between the base mold 22 and the mold body 21 on the outer periphery of the shoe sole, and the anti-skid shoe sole 1 formed with the shoe sole is formed with a projection having sharp corner edges 6. The
本発明の耐滑靴底の試験方法はステレンレス試験台を夫々乾燥状態、水で濡らした状態、サラダ油を塗った状態において、靴に荷重5kgを掛け、牽引速度30cm/分のとき、耐滑靴底の動摩擦係数を計測した。上記作製した耐滑靴底を備えた靴と従来靴(ブロック突起が立方形)との結果は次の表の通りで、本発明の耐滑靴底は乾燥状態のとき1.55、水で濡れた状態のとき1.45、サラダ油のとき1.25であり、何れの状態でも従来靴と比較して安定した耐滑機能の効果があることが判明した。また、官能評価において傾斜30度のステンレス板上の歩行テストでも被験者6名の平均は従来靴では5を最も良いとした5段階中1〜3であったのが、本発明の耐滑靴底を備えた靴では4〜5の評価であった。 The test method of the anti-skid shoe sole of the present invention is as follows. When a stainless steel test stand is dry, wet with water, and coated with salad oil, a load of 5 kg is applied to the shoe and the pulling speed is 30 cm / min. The dynamic friction coefficient was measured. The results of the above-prepared shoes with anti-skid shoe soles and conventional shoes (block projections are cubic) are as shown in the following table. The anti-skid shoe sole of the present invention is 1.55 when wet and wet with water. It was 1.45 in the state and 1.25 in the case of salad oil, and it was found that in any state, the effect of the stable anti-slip function was obtained as compared with the conventional shoes. In the sensory evaluation, the average of 6 subjects in the walking test on a stainless steel plate with an inclination of 30 degrees was 1 to 5 out of 5 levels, with 5 being the best for conventional shoes. The provided shoes were rated 4-5.
