Abstract
Description
本発明は靴に関し、より詳細には防水性に優れた靴に関する。 The present invention relates to a shoe, and more particularly to a shoe excellent in waterproofness.
雨の日の外出時や、ガーデニング、洗車といった水を使う作業時には、長靴を履いたり、防水性に乏しいタウンシューズの上にオーバーシューズを履いたりすることが通常行われている。 When going out on a rainy day or working with water such as gardening or car washing, it is common practice to wear boots or overshoes on poorly waterproof town shoes.
しかしながら、長靴はデザイン性に乏しく、また、オーバーシューズはあくまでも一時しのぎのものであり、結局、これらは上記のような特別なシチュエーションでしか使用することができなかった。 However, boots are poor in design, and overshoes are only temporary. Eventually, these shoes can only be used in the special situations as described above.
一方、熱可塑性樹脂により一体成形されかつ周縁の少なくとも一部に立上り部を有する靴底と、甲被の下縁部に中底を接合してなる靴本体とを備え、立上り部の内面に靴本体の下端部が接着されている靴が従来より知られている（下記特許文献１および２参照）。
On the other hand, a shoe sole that is integrally formed of a thermoplastic resin and has a rising portion at at least a part of the periphery, and a shoe main body formed by joining an insole to the lower edge portion of the upper, a shoe on the inner surface of the rising portion A shoe in which a lower end portion of a main body is bonded is conventionally known (see
上記の靴にあっては、熱可塑性樹脂製の靴底に一体に設けられた立上り部に、靴本体の下端部が接着されているため、通常の靴と比べると靴の内部に水が侵入し難い。 In the above shoes, since the lower end of the shoe body is bonded to the rising part that is integrally provided on the sole made of thermoplastic resin, water penetrates into the shoe compared to normal shoes. It is hard to do.
しかしながら、上記の靴の場合、立上り部が垂直または外側に広がった形状をしている上、立上り部の高さも靴本体の下端部までしか達していない。したがって、立上り部が靴本体から剥がれやすく、防水性も十分とは言えなかった。
本発明の目的は、優れた防水性を持ちながら、雨の日の外出時や水を使う作業時はもとより日常履きとしても広く使える靴を提供することにある。 An object of the present invention is to provide a shoe that has excellent waterproofness and can be widely used not only when going out on a rainy day or when using water, but also as everyday wear.
本発明による靴は、熱可塑性樹脂により一体成形されかつ周縁に環状立上り部を有する靴底と、甲被の下縁部に中底を接合してなる靴本体とを備え、立上り部は、靴本体の下部周面に沿い得る高さおよび曲面形状を有しており、立上り部の内側に靴本体の下部が嵌め込まれてその周面が立上り部内面に接着されていることを特徴とする。 A shoe according to the present invention includes a shoe sole that is integrally formed of a thermoplastic resin and has an annular rising portion at the periphery thereof, and a shoe main body formed by joining an insole to the lower edge portion of the upper, and the rising portion includes a shoe. It has a height and a curved surface shape that can be along the lower peripheral surface of the main body, and is characterized in that the lower portion of the shoe main body is fitted inside the rising portion and the peripheral surface is bonded to the inner surface of the rising portion.
上記の靴にあっては、靴底の周縁に一体に形成される立上り部が、環状のものであって、靴本体の下部周面に沿い得る高さおよび曲面形状を有しているので、この立上り部の内面に靴本体の下部周面が接着されることにより、立上り部が剥がれにくく、極めて高い防水性が得られる上、デザイン性にも優れている。したがって、本発明の靴によれば、雨の日の外出時や水を使う作業時はもとより、タウンシューズ等としても履くことができる。また、本発明の靴によれば、環状立上り部によって靴本体の下部周面が包み込まれているので、靴としての形態保持性に優れ、また、足の爪先の安全性の確保、足の踵のホールド性の向上による歩行機能の向上といった効果も得られる。 In the above shoes, the rising portion formed integrally with the periphery of the shoe sole is annular, and has a height and a curved surface shape that can be along the lower peripheral surface of the shoe body. By bonding the lower peripheral surface of the shoe body to the inner surface of the rising portion, the rising portion is difficult to peel off, extremely high waterproofness is obtained, and the design is excellent. Therefore, according to the shoe of the present invention, it can be worn as a town shoe or the like as well as when going out on a rainy day or when using water. Further, according to the shoe of the present invention, since the lower peripheral surface of the shoe body is encased by the annular rising portion, the shape retention as a shoe is excellent, the safety of the toe of the foot is ensured, and the heel of the foot The effect of improving the walking function due to the improvement of the holdability is also obtained.
本発明による靴において、靴底を形成している熱可塑性樹脂がエチレン酢酸ビニル共重合体（以下「ＥＶＡ」と略称する）であるのが好ましい。 In the shoe according to the present invention, the thermoplastic resin forming the sole is preferably an ethylene vinyl acetate copolymer (hereinafter abbreviated as “EVA”).
靴底をＥＶＡによって形成することにより、靴底の軽量化、ひいては靴全体の軽量化を図ることができる。もっとも、靴底は、ＥＶＡ以外の熱可塑性樹脂、例えば、サーモプラスチックラバー（ＴＲ）、ポリ塩化ビニル樹脂（ＰＶＣ）等により形成されていても勿論よい。 By forming the shoe sole by EVA, it is possible to reduce the weight of the shoe sole, and thus to reduce the weight of the entire shoe. Of course, the shoe sole may be formed of a thermoplastic resin other than EVA, for example, a thermoplastic rubber (TR), a polyvinyl chloride resin (PVC), or the like.
本発明の靴において、靴本体の甲被の材料は特に限定されないが、好ましくは、甲被の表面材が防水性を有する材料によって形成される。 In the shoe of the present invention, the material of the upper of the shoe main body is not particularly limited, but preferably, the surface material of the upper is formed of a waterproof material.
甲被の表面材が防水性を有する材料によって形成されていれば、靴としての防水性を更に高めることができる。なお、防水性を有する材料としては、合成皮革や、裏面にフィルムが貼着された防水生地等が挙げられる。 If the surface material of the upper is made of a waterproof material, the waterproof property as a shoe can be further enhanced. Examples of the waterproof material include synthetic leather and waterproof fabric having a film attached to the back surface.
また、本発明の靴において、立上り部の高さが、爪先部において１５〜２５ｍｍ、踵部において３０〜４５ｍｍ、長さ中央部において２０〜３０ｍｍであるのが好ましい。立上り部の高さが、爪先部で１５ｍｍ、踵部で３０ｍｍ、長さ中央部で２０ｍｍをそれぞれ下回ると、十分な防水性が得られなくなる恐れがある。一方、立上り部の高さが、爪先部で２５ｍｍ、踵部で４５ｍｍ、長さ中央部で３０ｍｍをそれぞれ越えると、甲被表面のうち立上り部によって覆われる部分の割合が多くなり、靴としてのデザイン性が損なわれる恐れがある。 Moreover, in the shoe of this invention, it is preferable that the height of a rising part is 15-25 mm in a toe part, 30-45 mm in a heel part, and 20-30 mm in a length center part. If the height of the rising portion is less than 15 mm at the toe portion, 30 mm at the heel portion, and 20 mm at the central portion of the length, there is a possibility that sufficient waterproofness cannot be obtained. On the other hand, when the height of the rising part exceeds 25 mm at the toe part, 45 mm at the heel part, and 30 mm at the center part of the length, the ratio of the part covered by the rising part on the upper surface increases, Design may be impaired.
図１および図２には、本発明の一実施形態が示されている。これらの図に示す靴(1)は、ＥＶＡにより一体成形されかつ周縁に環状立上り部(21)を有する靴底(2)と、甲被(4)の下縁部に中底(5)を接合してなる靴本体(3)とを備えている。
