Description

本発明は、魚釣りや運動やレジャ−に用いるフエルト製靴底の製造方法に関する。 The present invention relates to a method for manufacturing felt soles used for fishing, exercise and leisure.

川や海などの水辺や水中を歩行するときに苔などに足を取られやすいため、フエルト製の靴底を有する靴が用いられている。
例えば、釣りにおいては、フエルト製の靴底を有する短靴、長靴、足袋、サンダル、ウエ−ダ−(バカ長靴)など様々な種類の靴が用いられている。
これらの靴は、その靴底形状に合致した形状に形成された板状のフエルト製の靴底を有し、靴本体に接着されていたり、着脱して交換できるものもあり、交換用靴底も販売されている。
この様なフエルト製の靴底の靴を使用すると、歩行中の滑りはなくなるが、フエルトの減りが早いという問題がある。
そこで、従来以下の提案がされている。
Shoes that have felt soles are used because they can easily get their feet on moss and the like when walking in waterside or underwater such as a river or the sea.
For example, in fishing, various types of shoes such as boots having boots made of felt, boots, socks, sandals, and waders (baka boots) are used.
These shoes have a plate-like felt shoe sole formed in a shape that matches the shape of the shoe sole, and may be bonded to the shoe body or exchanged by attaching or detaching the shoe sole. Are also sold.
When such a felt shoe sole is used, slipping during walking is eliminated, but there is a problem that the felt is reduced quickly.
Therefore, the following proposals have been made conventionally.

特許文献1の公報にはフエルト製の靴底の接地面に溶融硬化させた複数の穴を設け、靴底の摩耗やほつれを生じにくくしたことが記載されている。
ところが、靴底の複数の穴は、ピアノ線製の金属棒を250度以上に加熱し靴底に当てて形成しているため溶融したフエルトの材料が金属棒に付着しており、金属棒を抜き取ると、靴底から溶融したフエルトの材料が引き延ばされて靴底に糸屑状に付着したり、また、金属棒側に付着したフエルトの材料を取り除かなければならないなど作業性が悪いという不具合があった。
実開平5−93204号公報
Patent Document 1 describes that a plurality of melted and hardened holes are provided on the ground contact surface of a felt shoe sole so that the shoe sole is less likely to be worn or frayed.
However, the holes in the shoe sole are formed by heating a metal rod made of piano wire to 250 degrees or more and applying it to the shoe sole, so the molten felt material is attached to the metal rod. When it is pulled out, the melted felt material is stretched from the shoe sole and adheres to the shoe sole in the form of lint, or the felt material attached to the metal rod side must be removed. There was a bug.
Japanese Utility Model Publication No. 5-93204

解決しようとする課題は、フエルト製靴底に金属棒を加熱し穴部を形成しようとするところに当てて溶融硬化させると溶融したフエルトの材料が金属棒に付着するため金属棒を抜き取ると靴底から溶融したフエルトの材料が引き延ばされて靴底に付着したり、金属棒側に付着したフエルト材を取り除かなければならないなど作業性が悪いことである。 The problem to be solved is that when the metal rod is heated on the felt shoe sole and applied to the hole to be melted and cured, the melted felt material adheres to the metal rod, so that the shoe sole is removed when the metal rod is removed. The melted felt material is stretched and adhered to the shoe sole, or the felt material adhered to the metal rod side must be removed, resulting in poor workability.

合成樹脂繊維がランダムに絡み合って形成された板状のフエルト材Fを台4の上に載置して靴底形状に合わせて切断具5で切断してフエルト製靴底3を形成する。
フエルト製靴底3の表面に熱源の送風機6を用いて熱風7を当て、フエルト製靴底3の繊維を構成する合成樹脂の融点より高い温度で加熱し、送風機6がフエルト製靴底3に触れないようにして溶融される。
フエルト製靴底3の繊維を溶融した後、硬化させて溶融硬化部Aを形成し、加熱前より表面から繊維がほつれないようにする。
A plate-like felt material F formed by intertwining synthetic resin fibers at random is placed on a table 4 and cut with a cutting tool 5 in accordance with the shape of the shoe sole to form a felt shoe sole 3.
Hot air 7 is applied to the surface of the felt shoe sole 3 using a blower 6 as a heat source, and heated at a temperature higher than the melting point of the synthetic resin constituting the fiber of the felt shoe sole 3 so that the blower 6 does not touch the felt shoe sole 3. To be melted.
After the fibers of the felt shoe sole 3 are melted, the fibers are cured to form a melt-cured portion A so that the fibers are not loosened from the surface before heating.

以下、本発明の実施形態を図面に基づき説明すると、図1から図4は第1実施例で、図1はフエルト製靴底の靴の外観図、図2はフエルト材からフエルト製靴底を切断する状態の断面側面図、図3はフエルト製靴底の斜視図、図4はフエルト製靴底に熱風で溶融硬化部を形成するときの側面図である。   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 are first examples, FIG. 1 is an external view of a shoe made of felt, and FIG. FIG. 3 is a perspective view of a felt shoe sole, and FIG. 4 is a side view of forming a melt-hardened portion with hot air on the felt shoe sole.

図1のフエルト製靴底の靴1は、水中を歩行するのに適した靴で、靴本体2がウレタン、クロロプレン等の発泡ゴムや発泡合成樹脂などの防水性、柔軟性を有する材料で足形に形成され、靴本体2の下側にフエルト製靴底3が接着等で固定されている。
フエルト製靴底3は、合成樹脂繊維が絡み合って形成されており水辺や水中等の歩行で滑りにくくなっている。
The felt shoe sole 1 shown in FIG. 1 is a shoe suitable for walking underwater, and the shoe body 2 is made of a waterproof and flexible material such as foamed rubber such as urethane or chloroprene or foamed synthetic resin. A felt shoe sole 3 is fixed to the lower side of the shoe body 2 by bonding or the like.
The felt shoe sole 3 is formed by intertwining synthetic resin fibers so that it is difficult to slip when walking in water or underwater.

フエルト製靴底3を形成するには、ポリプロピレン、ポリエチレン等の合成樹脂繊維の集合体にニ−ドルパンチを施し、さらに加圧して上記繊維がランダムに絡み合って形成された板状のフエルト材Fを形成する。   In order to form the felt shoe sole 3, a needle punch is applied to an aggregate of synthetic resin fibers such as polypropylene and polyethylene, and further pressed to form a plate-like felt material F formed by randomly intertwining the fibers. To do.

フエルト材Fの繊維は、繊度が2〜40デニ−ルで、繊維長は、10〜100mmを用いる。 そして、圧力200〜1000N/m
で3〜10分押圧し、密度0.1〜0.3g/cm とし、厚さ5〜30mmとしている。
The fiber of the felt material F has a fineness of 2 to 40 denier and a fiber length of 10 to 100 mm. And pressure 200-1000N / m < 2 >
At a density of 0.1 to 0.3 g / cm 3 and a thickness of 5 to 30 mm.

そして、図2のように板状のフエルト材Fを台4の上に載置して靴底形状に合わせて切断具5で切断して、接地面になる底面部3aとその反対側の靴本体2に止着する上面部3bと周縁に沿って側面部3cを有するフエルト製靴底3が形成される。 Then, as shown in FIG. 2, the plate-like felt material F is placed on the base 4 and cut with the cutting tool 5 in accordance with the shape of the shoe bottom, and the bottom surface portion 3a which becomes the ground contact surface and the shoe on the opposite side. A felt shoe sole 3 having an upper surface portion 3b to be fixed to the main body 2 and a side surface portion 3c along the periphery is formed.

さらに、フエルト材Fから切断したフエルト製靴底3の側面部3cの踵部3eがその繊維を構成する合成樹脂の融点より高い温度で加熱されて、溶融される。
この溶融は、図4のように電熱器を内蔵する送風機6を用いてフエルト製靴底3の表面に熱風7を当てておこなう。
送風機6は、ニクロム線に電流を流して発生する熱をプロペラを回して風で圧力をかけ送り出すようになっており、送風機6の送風口をフエルト製靴底3の表面に近づけて送り出された熱風7を当てフエルト製靴底3の表面(側面部3cの踵部3e)の繊維を溶融させる。
Further, the heel portion 3e of the side surface portion 3c of the felt shoe sole 3 cut from the felt material F is heated and melted at a temperature higher than the melting point of the synthetic resin constituting the fiber.
This melting is performed by applying hot air 7 to the surface of the felt shoe sole 3 using a blower 6 incorporating an electric heater as shown in FIG.
The blower 6 is configured to send out heat generated by passing an electric current through the nichrome wire by applying pressure to the wind by rotating a propeller. The blower 6 has a blower port brought close to the surface of the felt shoe sole 3 to send out hot air. 7 is applied to melt the fiber on the surface of the felt shoe sole 3 (the heel portion 3e of the side surface portion 3c).

上記溶融は、フエルト製靴底3を形成する繊維がポリプロピレン、ポリエチレンであるため温度160〜180℃で加熱しておこなう。
その後、冷却するか又は、常温で放置することで繊維同士が溶着した状態で硬化させる。
このようにしてフエルト製靴底3の繊維を溶融した後、硬化させた部分の溶融硬化部Aを形成し、側面部3cの踵部3eの表面から繊維がほつれないようになる。
また、溶融硬化部Aはその部分における表面の繊維すべてを溶融するのではなく表面に溶融されずに残る繊維があってもよい。
The melting is performed by heating at a temperature of 160 to 180 ° C. because the fiber forming the felt shoe sole 3 is polypropylene or polyethylene.
Then, it is hardened in a state where the fibers are welded by cooling or leaving at room temperature.
In this way, after the fibers of the felt shoe sole 3 are melted, the cured portion A of the cured portion is formed, so that the fibers are not frayed from the surface of the heel portion 3e of the side surface portion 3c.
Further, the melt-cured portion A may have fibers remaining on the surface without being melted, instead of melting all the fibers on the surface in the portion.

溶融作業において、熱源である送風機6はフエルト製靴底3に接触させないため溶融したフエルトの材料が送風機6に付着して引き延ばされて突出したり、送風機6に溶融したフエルトの材料が付着することがないため、フエルト製靴底3から送風機6に付着して引き延ばされたフエルト材の屑を取り除いたり、送風機6に付着したフエルトの材料を取り除くことがないため溶融硬化部Aが容易に形成でき、溶融硬化部Aを有するフエルト製靴底3を製造するための作業性が向上する。 In the melting operation, the blower 6 as a heat source is not brought into contact with the felt shoe sole 3, so that the melted felt material adheres to the blower 6 and is stretched and protrudes, or the melted felt material adheres to the blower 6. Therefore, it is possible to easily form the melt-cured portion A because the felt material attached to the blower 6 is not removed from the felt shoe sole 3 and the felt material attached to the blower 6 is not removed. This improves the workability for producing the felt shoe sole 3 having the melt-cured portion A.

第1実施例では溶融硬化部Aは、靴底3の踵部3dの側面部3c及び僅かに底面部3aに掛かるように形成したが、側面部3c全体や底面部3aに溶融硬化部Aを設けることもでき、送風機6の熱風7を溶融させたい部分に当てることで上記以外の様々な部分に溶融硬化部Aを形成することができる。
前記のようにフエルト製靴底3に溶融硬化部Aが形成されていると、フエルト製靴底3の繊維が摩耗やほつれが防止され、特にフエルト製靴底3の側面部3cの踵部3eは摩耗やほつれが起こりやすい部分であり溶融硬化部Aを設けるとフエルト製靴底3の耐久性が向上する。
In the first embodiment, the melt-cured portion A is formed so as to hang over the side surface portion 3c of the heel portion 3d and the bottom surface portion 3a of the shoe sole 3, but the melt-cured portion A is formed on the entire side surface portion 3c or the bottom surface portion 3a. It can also be provided, and the melt-hardened part A can be formed in various parts other than the above by applying the hot air 7 of the blower 6 to the part to be melted.
When the melt-hardened portion A is formed on the felt shoe sole 3 as described above, the fibers of the felt shoe sole 3 are prevented from being worn or frayed. In particular, the collar portion 3e of the side surface portion 3c of the felt shoe sole 3 is worn or worn. When the melt-hardened portion A is provided, which is a portion that is prone to fraying, the durability of the felt shoe sole 3 is improved.

図5は第2実施例で、フエルト製靴底に熱源を近づけて溶融硬化部を形成するときの側面図である。   FIG. 5 is a side view of a second embodiment when a melt-hardened portion is formed by bringing a heat source close to a felt shoe sole.

第2実施例ではフエルト製靴底3は第1実施例と同様に板状のフエルト材Fを台4の上に載置して靴底形状に合わせて切断具5で切断して製造され、フエルト製靴底3の側面部3cの踵部3eがこて8によってその繊維を構成する合成樹脂の融点より高い温度で加熱されて、溶融硬化部Aが形成されている。   In the second embodiment, the felt shoe sole 3 is manufactured by placing a plate-like felt material F on the table 4 and cutting it with the cutting tool 5 in accordance with the shape of the shoe sole, as in the first embodiment. The heel portion 3e of the side surface portion 3c of the shoemaking sole 3 is heated by the trowel 8 at a temperature higher than the melting point of the synthetic resin constituting the fiber, so that the melt-cured portion A is formed.

フエルト製靴底3の繊維を溶融するときは、熱源である金属のこて8を加熱してフエルト製靴底3の側面部3cの踵部3eに表面の繊維が溶融するまで近づけておこなう。
こて8はあらかじめ温度400℃程度に加熱しておきフエルト製靴底3の溶融硬化部Aを形成しようとする部分に一定の距離を保ってかざすことで加熱し溶融させる。
この場合、溶融硬化部Aを形成しようとする部分に沿ってこて8を移動させることで均一に溶融させることができる。
When the fibers of the felt shoe sole 3 are melted, the metal trowel 8 as a heat source is heated and brought close to the heel portion 3e of the side surface portion 3c of the felt shoe sole 3 until the surface fibers are melted.
The iron 8 is heated in advance to a temperature of about 400 ° C., and is heated and melted by holding it over a portion of the felt shoe sole 3 where the melt-hardened portion A is to be formed at a certain distance.
In this case, the trowel 8 can be moved uniformly along the portion where the melt-cured portion A is to be formed, so that it can be uniformly melted.

第2実施例においても溶融作業において、熱源であるこて8はフエルト製靴底3に接触させないため溶融したフエルトの材料がこて8に付着して引き延ばされて突出したり、こて8に溶融したフエルトの材料が付着することがないため、フエルト製靴底3からこて8に付着して引き延ばされたフエルト材の屑を取り除いたり、こて8に付着したフエルトの材料を取り除くことがないため溶融硬化部Aが容易に形成でき、溶融硬化部Aを有するフエルト製靴底3を製造するための作業性が向上する。   Also in the second embodiment, in the melting operation, the trowel 8 as a heat source is not brought into contact with the felt shoe sole 3, so that the molten felt material adheres to the trowel 8 and is stretched or protrudes or melts into the trowel 8 Since the felt material does not adhere, the felt material scrap attached to the trowel 8 from the felt shoe sole 3 can be removed, or the felt material attached to the trowel 8 can be removed. Therefore, the melt-cured portion A can be easily formed, and the workability for producing the felt shoe sole 3 having the melt-cured portion A is improved.

上記溶融の後、冷却するか又は、常温で放置することで繊維同士が溶着した状態で硬化させ、フエルト製靴底3の繊維を溶融した後硬化させた部分である溶融硬化部Aを形成し、加熱前の状態より表面(フエルト製靴底3の側面部3cの踵部3e)から繊維がほつれないようにできる。
他の構成は第1実施例と同じである。
After the melting, cooling or curing in a state where the fibers are welded by leaving at room temperature, forming a melt-cured portion A that is a portion cured after melting the fibers of the sole 3 made of felt, It is possible to prevent the fibers from fraying from the surface (the heel portion 3e of the side surface portion 3c of the felt shoe sole 3) from the state before heating.
Other configurations are the same as those of the first embodiment.

図6は第3実施例で、フエルト製靴底3に炎10で溶融硬化部を形成するときの側面図である。   FIG. 6 is a side view of the third embodiment when a melt-cured portion is formed on the felt shoe sole 3 with a flame 10.

第3実施例では フエルト製靴底3は第1実施例と同様に板状のフエルト材Fを台4の上に載置して靴底形状に合わせて切断具5で切断して製造され、フエルト製靴底3の側面部3cの踵部3eがバーナー9による炎10でその繊維を構成する合成樹脂の融点より高い温度で加熱されて、溶融硬化部Aが形成されている。   In the third embodiment, the felt shoe sole 3 is manufactured by placing a plate-like felt material F on the table 4 and cutting it with the cutting tool 5 in accordance with the shape of the shoe sole, as in the first embodiment. The heel part 3e of the side surface part 3c of the shoemaking sole 3 is heated at a temperature higher than the melting point of the synthetic resin constituting the fiber by the flame 10 by the burner 9, so that the melt-cured part A is formed.

バーナー9は、ガスやオイルを燃焼させて炎10を発生させ、フエルト製靴底3の溶融硬化部Aを形成しようとする部分(フエルト製靴底3の側面部3cの踵部3e)に炎10を当てるか、または、近づけることで加熱し溶融させる。
溶融の後、冷却するか又は、常温で放置することで繊維同士が溶着した状態で硬化させ、フエルト製靴底3の繊維を溶融した後、硬化させた部分である溶融硬化部Aを形成し、加熱前の状態より表面(フエルト製靴底3の側面部3cの踵部3e)から繊維がほつれないようにできる。
The burner 9 burns gas or oil to generate a flame 10, and the flame 10 is applied to a portion (a flange portion 3e of the side surface portion 3c of the felt shoe sole 3) where a melt-hardened portion A of the felt shoe sole 3 is to be formed. Heat or melt by applying or approaching.
After melting, it is cooled or allowed to stand at room temperature and cured in a state where the fibers are welded to each other, and after melting the fibers of the felt shoe sole 3, a melt-cured portion A that is a cured portion is formed, It is possible to prevent the fibers from fraying from the surface (the heel portion 3e of the side surface portion 3c of the felt shoe sole 3) from the state before heating.

第3実施例においても溶融作業において、熱源であるバーナー9はフエルト製靴底3に接触させないため溶融したフエルトの材料がバーナー9に付着して引き延ばされて突出したり、バーナー9に溶融したフエルトの材料が付着することがないため、フエルト製靴底3からバーナー9に付着して引き延ばされたフエルト材の屑を取り除いたり、バーナー9に付着したフエルトの材料を取り除くことがないため溶融硬化部Aが容易に形成でき、溶融硬化部Aを有するフエルト製靴底3を製造するための作業性が向上する。   Also in the third embodiment, in the melting operation, the burner 9 as a heat source is not brought into contact with the felt shoe sole 3, so that the molten felt material adheres to the burner 9 and is stretched or protrudes, or the felt melted in the burner 9. Therefore, it is not necessary to remove the waste of felt material attached to the burner 9 from the sole 3 made of felt and to remove the felt material attached to the burner 9, so that it is melt-cured. The part A can be easily formed, and the workability for manufacturing the felt shoe sole 3 having the melt-cured part A is improved.

上記溶融の後、冷却又は、常温で放置することで繊維同士が溶着した状態で硬化させ、フエルト製靴底3の繊維を溶融した後、硬化させた部分の溶融硬化部Aを形成し、加熱前の状態より表面(フエルト製靴底3の側面部3cの踵部3e)から繊維がほつれないようにできる。
