【背景技術および課題】[Background Technology and Issues]

本考案は外底と中底とを一体に積層してなる靴底に関する。 The present invention relates to a shoe sole in which an outer sole and an inner sole are integrally laminated.

【０００２】 従来の積層靴底は、靴底輪郭に截断した外底および中底シートを所望枚数接着 剤を使用し、または熱融着等の方法によって一体に積層したものであった。従っ て靴底の周縁端面においては積層シートの断面が露出するのでワックス，防水塗 料などを塗り、端面からの水の侵入を防止する必要があった。A conventional laminated shoe sole is one in which the desired number of sheets of outer soles and midsole sheets cut into the contour of the sole are laminated using an adhesive or by a method such as heat fusion. Therefore, the cross-section of the laminated sheet is exposed on the peripheral edge surface of the shoe sole, so it was necessary to apply wax, waterproof coating, etc. to prevent water from entering from the edge surface.

【０００３】 また全体が積層構造の靴底は層間で剥離する問題があり、かつ積層物底面と端 面とがほぼ直交するので障害物に引っかかり易いなどの欠点が見られる。Further, there is a problem that a shoe sole having an entirely laminated structure has a problem of peeling between layers, and the bottom surface of the laminated material and the end surface are substantially orthogonal to each other, which makes it easy to be caught by an obstacle.

【０００４】 そこで本考案は、外周縁において積層物の断面が露出せず、軽量であり、高強 度かつ障害物への引っかかりの少ない積層靴底を提供する。Therefore, the present invention provides a laminated shoe sole that is light in weight, does not expose the cross section of the laminated body at the outer peripheral edge, has high strength, and is less likely to be caught by an obstacle.

【解決方法】【Solutions】

本考案は、銀面を有する人工皮革外底層へ、少なくとも一層の中底層を銀面の 反対面に一体に積層してなる積層靴底に関する。本考案の課題は、靴底輪郭を有 する積層物の外周縁において外底層が中底層の反対面へ向ってカーブし船底形と なっていることによって解決される。 The present invention relates to a laminated shoe sole in which an artificial leather outer sole layer having a silver surface and at least one insole layer are integrally laminated on the surface opposite to the silver surface. The problem to be solved by the present invention is solved by the fact that the outer layer is curved toward the opposite side of the insole layer at the outer peripheral edge of the laminate having the sole contour to form a ship bottom.

【０００６】 このため本考案の靴底の外周縁は銀面を有する人工皮革外底層によって覆われ 、積層物の断面が露出しないからそこから水が侵入することはない。さらに外底 層と中底層とは周縁において熱融着されているから靴底は軽量にして高強度であ る。また外周縁は外底が銀面から中底反対面へ向ってなだらかにカーブしている ので障害物との引っかかりが少なく、安全である。For this reason, the outer peripheral edge of the shoe sole of the present invention is covered with the artificial leather outer sole layer having a silver surface, and since the cross section of the laminate is not exposed, water does not enter from there. Furthermore, since the outer sole layer and the middle sole layer are heat-sealed at the periphery, the shoe sole is lightweight and has high strength. Also, the outer edge is safe because the outer bottom is gently curved from the silver side to the opposite side of the insole, so there is little catching with obstacles.

【好ましい実施態様】 図面を参照すると、図１には本考案の靴底の横断面が示されている。靴底１０ は銀面を表にした人工皮革層１２と、複数層の発泡ＥＶＡ層１４とを同時プレス により一体に積層してなる。靴底１０の端縁１６において、人工皮革層１２は発 泡ＥＶＡ層の反対面へ向ってなだらかにカーブして船底形をなし、従って端縁１ ６は人工皮革層１２によって覆われ、積層物の断面が露出していない。この具体 例では銀面を有する人工皮革を外底層とし、中底は２層の発泡ＥＶＡ層で構成さ れているが、これらは靴底全体の厚みおよび個々のシートの厚みに応じて変更す ることが可能である。外底が銀面を有する人工皮革であり、最内側の中底層がＥ ＶＡシートである限り中間に用いる中底層の材質および枚数は任意である。例え ば最内側層を除いて中底層に人工皮革を使用してもよい。BEST MODE FOR CARRYING OUT THE INVENTION Referring to the drawings, FIG. 1 shows a cross section of a shoe sole of the present invention. The shoe sole 10 is formed by integrally laminating an artificial leather layer 12 having a silver surface and a plurality of foamed EVA layers 14 by simultaneous pressing. At the edge 16 of the sole 10, the artificial leather layer 12 is gently curved towards the opposite side of the foamed EVA layer to form a hull shape, so the edge 16 is covered by the artificial leather layer 12 and the laminate The cross section of is not exposed. In this example, an artificial leather having a silver surface is used as the outer sole layer, and the insole is composed of two layers of EVA foam. It is possible to As long as the outer sole is an artificial leather having a silver surface and the innermost inner sole layer is an EVA sheet, the material and the number of intermediate sole layers used in the middle are arbitrary. For example, artificial leather may be used for the insole layer except for the innermost layer.

【０００８】 靴底１０は、靴底１０に対応する立体形状を有するくぼみを有する雌型と、該 くぼみを覆う平坦な雄型よりなる金型を用意し、該くぼみより大きい輪郭を有す る人工皮革外底シートおよび所要枚数の中底シートを雌型の上に重ね、銀面の反 対面から雄型をもって加熱加圧して成形し得る。くぼみのカーブした周縁部分の 軟化した材料は中央部分よりも強い圧力を受け、くぼみ外側へはみ出して流れる 。成形後成形物を金型から取出し、くぼみ外側のはみ出し部分を切断除去すれば 本考案の靴底１０が得られる。For the shoe sole 10, a metallic mold having a hollow having a three-dimensional shape corresponding to the sole 10 and a flat male mold for covering the hollow is prepared, and has a contour larger than the hollow. An artificial leather outer bottom sheet and a required number of insole sheets may be stacked on a female mold, and a male mold may be heated and pressed from the opposite side of the silver surface to mold. The softened material on the curved periphery of the depression receives more pressure than the central portion and flows out of the depression. After molding, the molded product is taken out of the mold, and the protruding portion outside the recess is cut and removed to obtain the shoe sole 10 of the present invention.

【０００９】 本考案の靴底１０は、その後中底１４表面に外縁に沿ってリム部材２０を接着 し、踵は靴底１０本体の踵部にあらかじめ用意した任意の踵部材を接着等によっ て取付ける。好ましくは踵も靴底本体１０と同様に、中底１４側へ向ってカーブ した外底１２を有し、踵の外底と本体外底の間に踵が所望の高さとなるように発 泡ＥＶＡ層等を介在させる。雄型にリム部材に相当する空間形状を有するくぼみ を有する金型を用いることにより、リム部材を同時成形してもよい。In the shoe sole 10 of the present invention, a rim member 20 is then adhered to the surface of the insole 14 along the outer edge thereof, and the heel is adhered to the heel portion of the body of the shoe sole 10 by adhering any heel member prepared in advance. To install. Preferably, the heel also has an outsole 12 which is curved toward the side of the insole 14 like the shoe sole body 10, and foams so that the heel has a desired height between the outsole of the heel and the outsole of the body. An EVA layer or the like is interposed. The rim member may be simultaneously molded by using a mold having a recess having a space shape corresponding to the rim member for the male mold.

【００１０】 踵を本体１０の外底１２側に取付ける代りに、中底１４側に取付けてもよい。 その場合は爪先側へ向って傾斜した踵部材を用意し、本体１０の踵部の中底１４ の表面に該部材を接着等によって取付ける。Instead of attaching the heel to the outer sole 12 side of the main body 10, it may be attached to the inner sole 14 side. In that case, a heel member inclined toward the toe side is prepared, and the member is attached to the surface of the insole 14 of the heel portion of the main body 10 by adhesion or the like.

【００１１】 本考案の靴底１０はその外底１２の表面が一般に平坦である。そのため外底１ ２の所要部、特に親指のつけ根に相当する部分に滑り止めを設けるのが好ましい 。図２は滑り止め部材３０を設けた靴底１０の部分断面図である。滑り止め部材 ３０を取付ける部分には外底人工皮革１２に例えば円形の開口１８をくり抜き、 開口１８のまわりにカーブした周縁が形成されるように金型を用いてプレス成形 する。開口１８内の露出した中底１４の表面に、突起ないし凹凸を有する滑り止 め部材３０を接着等によって取付ける。部材３０は発泡ＥＶＡ，発泡ポリウレタ ン，ゴム等の弾力性シート材料でつくることができる。The shoe sole 10 of the present invention has a generally flat outer sole 12 surface. Therefore, it is preferable to provide a slip stopper at a required portion of the outer bottom 12, particularly a portion corresponding to the base of the thumb. FIG. 2 is a partial sectional view of the shoe sole 10 provided with the anti-slip member 30. For example, a circular opening 18 is hollowed out in the outer bottom artificial leather 12 at the portion where the anti-slip member 30 is attached, and press-molded using a mold so that a curved peripheral edge is formed around the opening 18. A non-slip member 30 having protrusions or irregularities is attached to the exposed surface of the insole 14 in the opening 18 by adhesion or the like. The member 30 can be made of a resilient sheet material such as foamed EVA, foamed polyurethane, rubber or the like.

【００１２】 図３は、ゴルフ靴へ鋲取付金具４０を固着した靴底１０の部分断面図である。 この場合所要個所に、内側に雌ねじ４４を有する円筒形鋲ソケット４２の外径に 相当する貫通孔を外底１２に設け、鋲ソケットが外底層１２を貫通するようにベ ースプレート４２を外底層１２と中底層１４の間に介在させ、外底層１２と中底 層１４とを同時プレスして金具４０を靴底１０に取付けたものである。図示しな い鋲はソケット４２の内部へねじ係合によって固着する。外底層１２の厚みによ っては、取付金具４０のベースプレート４６は中底層１４の層間に介在させても よい。FIG. 3 is a partial cross-sectional view of the shoe sole 10 with the tack fittings 40 fixed to the golf shoe. In this case, a through hole corresponding to the outer diameter of the cylindrical stud socket 42 having the internal thread 44 inside is provided in the required portion in the outer bottom 12, and the base plate 42 is provided so that the stud socket penetrates the outer bottom layer 12. The metal fitting 40 is attached to the shoe sole 10 by interposing between the inner sole layer 14 and the inner sole layer 14 and simultaneously pressing the outer sole layer 12 and the inner sole layer 14. The studs (not shown) are fixed to the inside of the socket 42 by screw engagement. Depending on the thickness of the outer bottom layer 12, the base plate 46 of the fitting 40 may be interposed between the middle bottom layer 14.

【００１３】 図４は、別の具体例による本考案の靴底を図示する図１と同様な断面図である 。この具体例による靴底１１０は、金型内において人工皮革外底層１１２の銀面 の反対面に液状発泡ポリウレタン樹脂組成物を注入し、発泡時の内圧によって靴 底外周縁を船底形状に成形すると同時に人工皮革層１１２と発泡ポリウレタン中 底層１１４とを積層、接着して製作する。液状発泡ウレタン樹脂組成物を用いる 場合はポリウレタン系人工皮革との接着性にすぐれているので、特にプライマー ，接着剤等を人工皮革層へ塗布しなくても十分な接着強度が得られる。FIG. 4 is a sectional view similar to FIG. 1, illustrating a shoe sole of the present invention according to another embodiment. The shoe sole 110 according to this example is obtained by injecting a liquid polyurethane foam resin composition into the outer surface of the artificial leather outer layer 112 in the mold, and molding the outer peripheral edge of the shoe sole into the shape of the ship bottom by the internal pressure during foaming. At the same time, the artificial leather layer 112 and the foamed polyurethane middle bottom layer 114 are laminated and adhered to each other. When the liquid foamed urethane resin composition is used, it has excellent adhesiveness to the polyurethane-based artificial leather, so that sufficient adhesive strength can be obtained without applying a primer or an adhesive to the artificial leather layer.

【００１４】 またこの具体例によれば、図２に示した滑り止め部材３０に相当する突起１３ ０をあらかじめ人工皮革外底１１２の所要個所に繰り抜いた開口内に同時成形す ることができる。この場合該開口の周囲の人工皮革層１１２はピン等の適当な部 材によって金型へぴったり押し付け、注入した液状発泡ポリウレタン樹脂組成物 が銀面へ拡散するのを防止する必要がある。同様に図１のリム部材２０に相当す るリム１２０も発泡ポリウレタンによって中底１１４と同時成形することができ る。Further, according to this specific example, the protrusion 130 corresponding to the anti-slip member 30 shown in FIG. 2 can be simultaneously formed in the opening that has been cut out in advance at a required portion of the artificial leather outer bottom 112. .. In this case, it is necessary that the artificial leather layer 112 around the opening is exactly pressed against the mold by an appropriate member such as a pin to prevent the injected liquid foamed polyurethane resin composition from diffusing to the silver surface. Similarly, a rim 120 corresponding to the rim member 20 in FIG. 1 can be simultaneously molded with the insole 114 by using polyurethane foam.

【００１５】 本考案の靴底は、弾力性材料の滑り止め部材３０または１３０を形成すること によりタウンシューズにも適合し、また鋲取付金具４０を設けることによりゴル フ靴にも適合する。いずれの場合も軽量にして強度にすぐれ、靴底の周端縁から 水の侵入を防止でき、さらに障害物への引っかかりが少ない利益を発揮できる。The shoe sole of the present invention is suitable for town shoes by forming the anti-slip member 30 or 130 of elastic material, and also for golf shoes by providing the tack fittings 40. In any case, it is lightweight and has excellent strength, water can be prevented from entering from the peripheral edge of the shoe sole, and the advantage of less catching on obstacles can be achieved.
