【発明が解決しようとする課題】
上記従来の防水性を有する靴は、「アッパー(10)と軟質のライニング(20)とを接着或いは縫合方式により接合し、靴型をライニング(20)内に押し込み、完全な靴形状を形成させ、一体成形の防水カバー体(30)を完全な靴形状を成すライニング(20)の外側に嵌め込んで中間層を形成させ、ライニング(20)と防水カバー体(30)とを均一に貼り合わせ、次に、前記防水カバー体(30)の外表面全てに接着剤を塗布し、内表面が平坦状となり、且つ異物感が残らないように、アッパー(10)に貼り合わせて、中間層とアッパー(10)とを完全に接合させ、最後に、表底(40)の上面に接着剤を塗布して中間層の裏地底部に貼り合わせることにより、防水性を有する靴を製造するものである。そして、前記不透水性の防水カバー体(30)はゴム、ポリエチレン、ポリプロピレン、又はポリカーボネートから成ると共に、射出成形或いは塗布により形成され、この塗布では素材をモールド上に付着させ、硬化した後取出すという成形方法である。また、材料中では張力及び弾性を有するゴムが防水カバー体(30)の材料として最も適当である。」と記載されている。
【0005】
しかし、上記従来の防水性を有する靴は、であり、防水効果はあるとしても履く人の足が直接、防水カバー体(30)に触れることとなり、汗等が防水カバー体(30)であるゴム、ポリエチレン等の成形品の表面に付着され、水虫や足に炎症等を起こす原因ともなり、履く人の不快感が増すこととなる。
【0006】
また、上記従来の防水靴以外に、樹脂コーテイング布帛や樹脂フィルムのラミネート布帛があるが、樹脂コーテイング布帛は表面が樹脂でコーテイングされているために、靴形状が硬化したものとなり、履く人にフィット感が無く、樹脂フィルムのラミネート布帛は剥離する等の問題があった。
【0007】
本発明は上記の点に鑑みてなされたもので、その目的とするところは、裏地に形成する防水膜は接着剤を使用することなく裏地に強力に略均一に付着形成することができる柔軟性を有する防水膜であって、防水性が得られることは勿論のこと、従来の履物と同様に履く人に何ら違和感が無く、柔軟性を有し、履く人にフィット感を与える防水型履物及びその製造方法を提供することにある。
【0008】
【課題を解決するための手段】
本発明に係る防水型履物は、裏地材にて足裏形状に裁断した裏地底部と、該裏地材と同種又は異種の裏地材にて踵部で折り返し足の甲部で突き合わせ縫着した甲状裏地部とを縫着してなるインナー靴基体を形成し、該インナー靴基体の全表面に、粘着剤を含有するラテックスを主成分とする防水膜又は粘着材を含有する熱可塑性エラストマー等の柔軟材からなる防水膜を略均一に付着形成するとともに、前記インナー靴基体の裏地底部を除く表面をアッパー部にて被包し、かつ該アッパー部の下部周縁はインナー靴基体の裏地底部に当接する中底の周縁に固着形成したものである。
【0009】
本発明に係る防水型履物の製造方法は、裏地材にて足裏形状に裁断した裏地底部と、該裏地材と同種又は異種の裏地材にて踵部で折り返し足の甲部で突き合わせ縫着した甲状裏地部とを縫着してなるインナー靴基体を形成した後、該インナー靴基体にラスト(靴型)を入れ、該ラストに装着したインナー靴基体の全表面を、粘着剤を含有するラテックスを主成分とする液状粘性材に浸漬後、取り出して熱加硫固化させ、インナー靴基体の防水膜を略均一に付着形成し、次いで、前記インナー靴基体の裏地底部を除く表面をアッパー部にて被包し、該アッパー部の下部周縁はインナー靴基体の裏地底部に接着した中底の周縁に固着形成したものである。
【0010】
【実施例】
以下、本発明の一実施例を図面に基いて説明する。
図1は本発明の一実施例を示すインナー靴基体の斜視図、図2は図1のA−A線断面図、図3は本発明の靴の製造工程の一工程を示す斜視図、図4は本発明の靴の製造工程の一工程を示す斜視図、図5は本発明の靴の製造工程の一工程を示す一部切欠断面を示す斜視図である。
1はインナー靴基体で、裏地材にて足裏形状に裁断した裏地底部2と、裏地材と同種又は異種の裏地材にて踵部で折り返し足の甲部で突き合わせ縫着した甲状裏地部3とを縫着して得られる。裏地材は例えば人の足に触れる側に汗等に対応でき、肌触りの良いメッシュタイプの繊維素材で、外側は連泡(非独立気泡)のウレタン発泡樹脂の組合せや、吸水性で、通気性が良好な材料の単独あるいは併用、その他、足にやさしい繊維、生地、革材等の素材が使用される。裏地底部2と甲状裏地部3を個別に形成して両者を縫着することとしたのは足型形状に適合せしめることと、縫着部が後述する防水膜4により一層強固に補強されることによるものである。また裏地底部2と甲状裏地部3とを異種の裏地材にて形成した場合は、足の側面に比べ足裏には過酷な条件が加わるので足裏に適した材料で形成できるというメリットがある。
【0011】
インナー靴基体1を形成した後、そのインナー靴基体1にラスト(靴型)5を入れて、インナー靴基体1にラスト(靴型)5の形状を維持させる。
ラスト5に装着したの裏地底部2全体及び甲状裏地部3の全表面を、粘着剤を含有するラテックスを主成分とする液状粘性材に浸漬する。インナー靴基体1を液状粘性材に浸漬するときに、インナー靴基体1の内部(内側)に液状粘性材が進入しないように浸漬する深さに注意を払う必要がある。浸漬後、取り出して100℃から120℃の温度に数十分間加温して熱加硫固化させる。インナー靴基体1の防水膜4を略均一に表面に付着形成させる。
インナー靴基体1の表面に付着形成させる防水膜4は、例えば天然ラテックスにMPM、TS亜鉛剤、硫黄等の硫化物を配合して調整し、染料で色付け後、粘着剤を適量添加する。粘着剤としては、例えばEVA等の粘着付与樹脂を加え、さらにワックスや可塑剤、酸化防止剤等の添加剤等を加えて製造するか、あるいはロジン系、テルペン系、石油樹脂、石炭酸樹脂等の粘着付与樹脂を添加するか、メチルセルロース、アルギン酸塩などの増粘剤が添加される。本発明では天然ラテックスを例に挙げ説明したが合成ラテックスでも良い。
ラテックス単独使用の場合は、ある程度の粘着性はあるが、インナー靴基体1の表面への付着が十分でなく、また均一な防水膜が得られないのに対して、粘着剤を含有するラテックスを主成分とする防水膜4とすることにより、接着剤を要することなく表面への接着力が強固でゴムによる防水効果が完全となり、柔軟性に富み、膜厚も略均一化される。
またインナー靴基体1の防水膜4の形成に当っては、前記以外の材料として粘着材を含有する熱可塑性エラストマー等の柔軟材からなる防水膜が採用されるが、いずれにしてもゴム状の柔軟性を有し、インナー靴基体1の表面に付着形成するときに剥離することなく強固に固着されることが肝要である。
【0012】
次いで、前記インナー靴基体1の裏地底部2を除く表面をアッパー部6にて被包する。アッパー部6の下部周縁は吊り込み状態にしてインナー靴基体1の裏地底部2に接着した中底7の周縁に固着形成する。インナー靴基体1の裏地底部2に中底7を設けることにより履き心地良く、安定感が増すこととなる。
そして、最後に接着剤等により中底7に裏側に本底(表底)8を固着する。
【0013】
【発明の効果】
本発明は、上記の説明から判るように、裏地に形成する防水膜は接着剤を使用することなく裏地に強力に略均一に付着形成することができる。しかも柔軟性を有する防水膜であって、完全に防水性が得られることは勿論のこと、従来の履物と同様に履く人に何ら違和感が無く、柔軟性を有し、履く人にフィット感を与える防水型履物を簡便かつ確実に良好な製品が得られる。

After being immersed in a liquid viscous material containing latex as a main component, taken out and thermally vulcanized and solidified, a waterproof film of the inner shoe base is adhered and formed substantially uniformly, and then the surface of the inner shoe base except for the lining bottom is formed of an upper part. The lower edge of the upper portion is fixedly formed on the edge of the midsole adhered to the lining bottom of the inner shoe base.
[0010]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an inner shoe base showing one embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a perspective view showing one step of a manufacturing process of the shoe of the present invention. 4 is a perspective view showing one step of the shoe manufacturing process of the present invention, and FIG. 5 is a perspective view showing a partially cutaway cross section showing one step of the shoe manufacturing process of the present invention.
Reference numeral 1 denotes an inner shoe base, a lining bottom portion 2 cut into a sole shape with a lining material, and a thyroidal lining portion 3 folded and sewn at a heel portion with a heel portion using a lining material of the same or different type as the lining material 3 and sewn. And obtained by sewing. The lining material is a mesh-type fiber material that can respond to sweat, etc. on the side that touches human feet, and has a soft touch, and the outside is a combination of open-cell (non-closed cell) urethane foam resin, water-absorbing, and breathable Or a combination of good materials, and foot-friendly materials such as fiber, fabric, and leather. The lining bottom portion 2 and the thyroid lining portion 3 are separately formed and sewn together to conform to the shape of the last, and the sewn portion is further reinforced by the waterproof film 4 described later. It is due to. Further, when the lining bottom 2 and the thyroid lining 3 are formed of different types of lining materials, severe conditions are applied to the soles compared to the side surfaces of the feet, so that there is an advantage that the linings can be formed of a material suitable for the soles. .
[0011]
After the inner shoe base 1 is formed, the last (shoe last) 5 is put into the inner shoe base 1, and the shape of the last (shoe last) 5 is maintained on the inner shoe base 1.
The entire lining bottom 2 and the entire surface of the thyroid lining 3 attached to the last 5 are immersed in a liquid viscous material mainly composed of latex containing an adhesive. When immersing the inner shoe base 1 in the liquid viscous material, it is necessary to pay attention to the depth of immersion so that the liquid viscous material does not enter the inside (inside) of the inner shoe base 1. After immersion, it is taken out and heated to a temperature of 100 ° C. to 120 ° C. for several tens minutes to be thermally vulcanized and solidified. The waterproof film 4 of the inner shoe base 1 is adhered and formed substantially uniformly on the surface.
The waterproof film 4 adhered to the surface of the inner shoe base 1 is adjusted by, for example, blending MPM, TS zinc agent, sulfide such as sulfur with natural latex, coloring with a dye, and then adding an appropriate amount of an adhesive. As the pressure-sensitive adhesive, for example, a tackifier resin such as EVA is added, and further, an additive such as a wax, a plasticizer, an antioxidant, or the like is added. A tackifier resin is added, or a thickener such as methylcellulose or alginate is added. In the present invention, natural latex has been described as an example, but synthetic latex may be used.
When the latex is used alone, it has a certain degree of tackiness, but it does not adhere sufficiently to the surface of the inner shoe base 1 and a uniform waterproof film cannot be obtained. By forming the waterproof film 4 as a main component, the adhesive force to the surface is strong without the need for an adhesive, the waterproof effect by rubber is perfect, the flexibility is high, and the film thickness is substantially uniform.
In forming the waterproof film 4 of the inner shoe base 1, a waterproof film made of a flexible material such as a thermoplastic elastomer containing an adhesive is used as a material other than the above, but in any case, a rubber-like material is used. It is important that it has flexibility and is firmly fixed without peeling off when it is formed on the surface of the inner shoe base 1.
[0012]
Next, the surface of the inner shoe base 1 excluding the lining bottom 2 is covered with the upper part 6. The lower peripheral edge of the upper portion 6 is suspended and fixed to the peripheral edge of the inner sole 7 adhered to the lining bottom 2 of the inner shoe base 1. By providing the inner sole 7 on the lining bottom 2 of the inner shoe base 1, comfort is improved and a sense of stability is increased.
Finally, the outsole (outsole) 8 is fixed to the midsole 7 on the back side with an adhesive or the like.
[0013]
【The invention's effect】
According to the present invention, as can be seen from the above description, the waterproof film formed on the lining can be strongly and substantially uniformly adhered to the lining without using an adhesive. In addition, it is a waterproof membrane that has flexibility, so that it is completely waterproof, and as with conventional footwear, there is no discomfort for the wearer, and it has flexibility and fit for the wearer. A good product can be obtained simply and reliably by giving waterproof footwear.
