Description

【０００１】
【発明の属する技術分野】
本発明は、すくい縫い及び根巻きにより一のボタンを被縫製物に縫い付ける根巻きボタン付けミシンの被縫製物支持具に関するものである。
【０００２】
【従来の技術】
従来、この種の被縫製物支持具として、ミシンによる一のボタンの被縫製物へのすくい縫い及び根巻きに際し、端部にて被縫製物を曲折させて支持する曲折支持部を有するものが知られている。この被縫製物支持具は一般にタングと呼ばれ、水平方向に延びるよう形成され、ミシンの針が上下動する領域に被縫製物を水平方向に折り曲げた状態で支持する。
【０００３】
この被縫製物支持具が装着されたミシンにおいては、まず、ミシンのチャック等によりボタンを水平方向に支持した状態で被縫製物の曲折部分にすくい縫いを施す。この後、被縫製物を被縫製物支持具に支持させたまま、ボタンと被縫製物とを水平方向に離隔してボタンを垂直方向に支持することにより、ボタンと被縫製物との間で糸を緊張させて、糸に根巻きを施す。これにより、根巻き処理が施された状態で、ボタンがミシンにより被縫製物に縫い付けられる。
【０００４】
ところで、ボタンの被縫製物への縫い付け形態として、上記のように、一のボタンをすくい縫い及び根巻きにより縫い付ける他に、被縫製物の一面に配される上ボタンと、被縫製物の他面に配される下ボタンからなる二のボタンを縫い付ける形態もある。これによれば、下ボタンに上ボタンからの負荷が加わるので、被縫製物に直接的に縫い付けられるものに比べ、ボタンの取付強度が格段に向上する。
【０００５】
このように、被縫製物に上ボタン及び下ボタンを取り付ける際にも根巻きが施される。この根巻きを行う際には、上ボタン側及び下ボタン側を鉛直に保持する必要がある。しかし、前記ミシンではチャック等により一のボタンを保持することができるものの、二のボタンを保持することはできない。従って、衣服を製造する工場等においては、被縫製物に一のボタンを縫い付けるミシンと、被縫製物に二のボタンを縫い付けるミシンとを別個に設置している。
【０００６】
【発明が解決しようとする課題】
このように、工場等においては、すくい縫い及び根巻きを行って一のボタンを被縫製物に縫い付けるミシンと、上ボタン及び下ボタンが既に縫製された被根巻き縫製物の根巻きのみを行う専用のミシンとを別個に設置し、製品に応じて使用するミシンを使い分ける必要があり、工場等にて衣服等を生産する際の自由度が低いという問題点があった。
【０００７】
本発明は前記事情に鑑みてなされたものであり、その目的とするところは、一台のミシンで、被縫製物のすくい縫い及び根巻きに加え、上ボタン及び下ボタンが既に縫製された被根巻き縫製物の根巻きをも行うことのできる根巻きボタン付けミシンの被縫製物支持具を提供することにある。
【０００８】
【課題を解決するための手段】
前記目的を達成するため、例えば、図１から図７に示すように、
請求項１記載の発明では、根巻きボタン付けミシン（１００）に装着される支持具本体（３）と、
前記支持具本体に略水平方向に延びるよう形成され、前記ミシンによる一のボタン（８）の被縫製物（２）へのすくい縫い及び根巻きに際し、端部にて前記被縫製物を曲折させて支持する曲折支持部（４）と、
前記曲折支持部の上方に出没自在となるよう前記支持具本体に設けられ、前記曲折支持部の上方位置にて略鉛直方向に延びる状態となり、上ボタン（９）及び下ボタン（１０）が既に縫製された被根巻き縫製物（１１）における前記下ボタン側の糸（１２）を上端にて支持し、前記被根巻き縫製物の前記上ボタン側の面を一側面にて支持する下ボタン用支持部（５）とを備えたことを特徴とする。
尚、ここでいう被縫製物とは、未だ一のボタンのすくい縫い及び根巻き処理が施されていない生地をいう。また、被根巻き縫製物とは、一面側に上ボタンが配され、他面側に下ボタンが配されるように、上ボタン及び下ボタンが既に縫製された生地であって、上ボタンと生地の間の糸に、未だ根巻き処理が施されていないものをいう。
【０００９】
請求項１記載の発明によれば、ミシンにて針が上下動する領域にて被縫製物と被根巻き縫製物とを選択的に支持して、被縫製物のすくい縫い及び根巻きと、被根巻き縫製物の根巻きとが選択的に行われる。
すなわち、下ボタン用支持部が曲折支持部の上方から退去した状態では、曲折支持部にて被縫製物が支持され、被縫製物のすくい縫い及び根巻きが行われる。
また、下ボタン用支持部が曲折支持部の上方に出現した状態では、下ボタン用支持部にて被根巻き縫製物の下ボタン側の糸を支持するとともに、被根巻き縫製物の上ボタン側の面が支持される。このとき、被根巻き縫製物の上ボタン側を、ミシンに設けられたチャック、或いは、支持具本体に設けられた他の支持部等によって支持することにより、上ボタンと生地との間で糸が水平方向に緊張した状態となり、根巻き処理が可能となる。
従って、下ボタン用支持部を移動させることにより、曲折支持部による被縫製物の支持と、下ボタン用支持部による被根巻き縫製物の支持とを選択的に行うことができ、一台のミシンで、被縫製物のすくい縫い及び根巻きに加え、上ボタン及び下ボタンが既に縫製された被根巻き縫製物の根巻きをも行うことができる。
【００１０】
請求項２記載の発明では、請求項１記載の根巻きボタン付けミシンの被縫製物支持具において、
前記下ボタン用支持部を回動自在に前記支持具本体に設け、
前記下ボタン用支持部が、前記曲折支持部の上方位置と、前記曲折支持部から離隔した格納位置とに選択的に位置するよう構成したことを特徴とする。
【００１１】
請求項２記載の発明によれば、請求項１の作用に加え、下ボタン用支持部が回動自在であるので、下ボタン用支持部の移動を簡単な構成で行うことができ、曲折支持部の上方への出没を極めて容易に行うことができる。
また、下ボタン用支持部が上方位置と格納位置とに選択的に位置するよう構成したので、下ボタン用支持部が各位置の中間に定常的に位置することはなく、下ボタン用支持部の曲折支持部の上方への出没を的確に行うことができる。
ここで、下ボタン用支持部が上方位置と格納位置とに選択的に位置する構成として、支持具本体を略水平に延びるよう形成するとともに支持具本体の一端側に曲折支持部を形成し、下ボタン用支持部を支持具本体の上面側に回動自在に設け、下ボタン用支持部が支持具本体の一端側と当接すると曲室支持部の上方位置となり、他端側と当接すると格納位置となるよう構成することが好ましい。
【００１２】
請求項３記載の発明では、請求項１または２記載の根巻きボタン付けミシンの被縫製物支持具において、
前記曲折支持部の上方に出没自在となるよう前記支持具本体に設けられ、前記曲折支持部の上方位置にて略鉛直方向に延びるとともに前記下ボタン用支持部と間隔をおいて略平行となる状態となり、前記被根巻き縫製物における前記上ボタン側の糸を上端にて支持し、前記下ボタン用支持部に対して反対側の面にて前記上ボタンの一面を支持する上ボタン用支持部（６）を有することを特徴とする。
【００１３】
請求項３記載の発明によれば、請求項１または２の作用に加え、下ボタン用支持部及び上ボタン用支持部が曲折支持部の上方に出現した状態で、下ボタン用支持部にて被根巻き縫製物の下ボタン側の糸を支持するとともに被根巻き縫製物の上ボタン側の面が支持され、上ボタン用支持部にて被根巻き縫製物の上ボタン側の糸を支持するとともに被根巻き縫製物の上ボタンの一面が支持される。
これにより、上ボタンと生地との間で糸が水平方向に緊張した状態となり、被根巻き縫製物の根巻き処理が可能となる。
【００１４】
請求項４記載の発明では、請求項３記載の根巻きボタン付けミシンの被縫製物支持具において、
前記下ボタン用支持部及び前記上ボタン用支持部を一体的に設け、前記下ボタン用支持部と、前記上ボタン用支持部との距離を調整する調整機構を設けたことを特徴とする。
【００１５】
請求項４記載の発明によれば、請求項３の作用に加え、被根巻き縫製物における、糸を水平方向に緊張させた際の、生地と上ボタンとの間の距離に応じて、下ボタン用支持部と上ボタン用支持部との距離を調整することにより、生地と上ボタンとの距離が異なる被根巻き縫製物の根巻きを行うことができ、実用に際して極めて有利である。
【００１６】
【発明の実施の形態】
図１から図７は、本発明の一実施形態を示すもので、図１は被縫製物支持具を装着した状態を示すミシンの外観斜視図、図２は下ボタン用支持部が曲折支持部の上方に位置した状態を示す被縫製物支持具の外観斜視図、図３は下ボタン用支持部が曲折支持部から離隔した状態を示す被縫製物支持具の外観斜視図、図４は被根巻き縫製物を下ボタン用支持部及び上ボタン用支持部にて支持した状態を示す被縫製物支持具の外観斜視図、図５は被根巻き縫製物を下ボタン用支持部及び上ボタン用支持部にて支持した状態を示す被縫製物支持具の一部側面図、図６は曲折支持部にてすくい縫いを施すよう被縫製物を支持した状態を示す被縫製物支持具の一部側面図、図７は曲折支持部にて根巻きを施すよう被縫製物を支持した状態を示す被縫製物支持具の一部側面図である。
【００１７】
図１に示すように、この被縫製物支持具１は、根巻きボタン付けミシン１００に装着される。ここで、根巻きボタン付けミシン１００は、ミシンの上部をなし前後方向に延びるミシンアーム１０１と、ミシンの下部をなし前後方向に延びるミシンベッド１０２とを有する外形が側面視にて略コ字状を呈するミシンフレーム１０３を備えている。また、根巻きボタン付けミシン１００はミシンアーム１０１側に設けられ被縫製物２の縫製を行う針１０４を備えている。被縫製物支持具１は針１０４が上下動する領域にて被縫製物２を支持する位置に配される。以下、被縫製物支持具１について詳述する。
【００１８】
図２及び図３に示すように、この被縫製物支持具１は、ミシン１００に装着される支持具本体３と、支持具本体３に略水平方向に延びるよう形成された曲折支持部４と、曲折支持部４の上方に出没自在となるよう支持具本体３に設けられた下ボタン用支持部５及び上ボタン用支持部６とを備えている。
【００１９】
支持具本体３は、ミシン１００のミシンベッド１０２に形成された取付軸１０２ａに取り付けられる取付部３ａと、取付部３ａに接続され端部に曲折支持部４が形成される接続部３ｂとを有している。取付部３ａには取付軸１０２ａに嵌め込まれる嵌合孔３ｃが形成される。ここで、取付軸１０２ａは針１０４が上下動する領域の下方に形成されており、取付部３ａは針１０４側に凹となるよう湾曲して形成される。すなわち、取付部３ａは取付軸１０２ａから水平方向に離隔しつつ上方に延びることとなる。
【００２０】
接続部３ｂは、取付部３ａに接続される板状の傾斜延在部３ｄと、傾斜延在部３ｄと連続して形成されこれまた板状の水平延在部３ｅとを有している。傾斜延在部３ｄは針１０４側に近接する方向に傾斜して延び、ねじ等により取付部３ａに接続される。図１に示すように、水平延在部３ｅはミシンベッド１０２側の支持台１０２ａの上面と当接し、その端部が針１０４の上下動する領域に位置するよう固定される。尚、この端部には、前述のように、曲折支持部４が形成されている。
【００２１】
図３に示すように、曲折支持部４は、水平延在部３ｅの端部の幅方向中央側に切欠４ａを形成することにより構成される。この結果、図６及び図７に示すように、切欠４ａに針１０４及び糸７を挿通可能な状態となるように、曲折支持部４に被縫製物２を曲折して支持させることが可能となる。すなわち、図６に示すように、ボタン８をチャック等により水平方向に支持して被縫製物２にすくい縫いを施すことができるし、また、図７に示すように、すくい縫いが施された後、ボタン８を鉛直方向に支持するとともに被縫製物２から水平方向に離隔して糸７に根巻きを施すことができる。
【００２２】
図２に示すように、下ボタン用支持部５は、上ボタン９及び下ボタン１０が既に縫製された被根巻き縫製物１１を上端にて支持する鉛直延在部５ａと、鉛直延在部５ａの下端に一端が接続され支持具本体３の水平延在部３ｅの長手方向中央側へ延びる水平延在部５ｂとを有している。この水平延在部５ｂの他端は、支持具本体３の水平延在部３ｅに回動自在に接続される。これにより、下ボタン用支持部５の鉛直延在部５ａは、図２に示すように、水平延在部５ｂの一面側が支持具本体３の水平延在部３ｅの上面と当接した状態で曲折支持部４の上方に位置し、図３に示すように、水平延在部５ｂの他面側が支持具本体３の水平延在部３ｅの上面と当接した状態で曲折支持部４から離隔した位置となる。
【００２３】
鉛直延在部５ａは上端の幅方向中央側に形成された切欠５ｃを有する。この結果、図４に示すように、鉛直延在部５ａに、切欠５ｃに糸１２を挿通させて糸１２を支持させるとともに、被根巻き縫製物１１の上ボタン９側の面を一側面にて支持させることが可能となる。
【００２４】
図２に示すように、上ボタン用支持部６は、前述の被根巻き縫製物１１を上端にて支持する鉛直延在部６ａと、鉛直延在部６ａの下端に一端が接続され下ボタン用支持部５の水平延在部５ｂの長手方向中央側へ延びる水平延在部６ｂとを有している。この水平延在部６ｂの他端は、下ボタン用支持部５の水平延在部５ｂの長手方向中央と接続される。本実施形態においては、上ボタン用支持部６の下面と、下ボタン用支持部５の上面とが当接するよう各ボタン用支持部５，６が配される。上ボタン用支持部６の水平延在部６ｂには長手方向に延びる溝６ｃが形成され、下ボタン用支持部５の水平延在部５ｂの上面には、この溝６ｃを挿通するボルト部材５ｄが形成される。そして、ボルト部材５ｄと螺合するナット１３により、上ボタン用支持部６は下ボタン用支持部５に固定されるようになっている。
【００２５】
ここで、ボルト部材５ｄは、溝６ｃ内を自在に移動し、下ボタン用支持部５と上ボタン用支持部６との距離が調整可能となっている。すなわち、本実施形態においては、溝６ｃ、ボルト部材５ｄ、ナット１３等により、調整機構が構成されている。
【００２６】
鉛直延在部６ａは上端の幅方向中央側に形成された切欠６ｄを有する。この結果、図４及び図５に示すように、鉛直延在部６ａに、切欠６ｄに糸１２を挿通させて糸１２を支持させるとともに、被根巻き縫製物１１の上ボタン９の一面を支持することが可能となる。
【００２７】
以上のように構成された被縫製物支持具１においては、ミシン１００にて針１０４が上下動する領域にて被縫製物２と被根巻き縫製物１１とを選択的に支持して、被縫製物２のすくい縫い及び根巻きと、被根巻き縫製物１１の根巻きとが選択的に行われる。
【００２８】
すなわち、図３、図６及び図７に示すように、下ボタン用支持部５が曲折支持部４の上方から退去した状態では、曲折支持部４にて被縫製物２が支持され、被縫製物２のすくい縫い及び根巻きが行われる。
【００２９】
また、図２、図４及び図５に示すように、下ボタン用支持部５が曲折支持部４の上方に出現した状態では、下ボタン用支持部５にて被根巻き縫製物１１の下ボタン１０側の糸を支持するとともに、被根巻き縫製物１１の上ボタン９側の面が支持される。このとき、被根巻き縫製物１１の上ボタン９側を、支持具本体３に設けられた上ボタン支持部６によって支持することにより、上ボタン９と被根巻き縫製物１１との間で糸１２が水平方向に緊張した状態となり、根巻き処理が可能となる。
【００３０】
本実施形態においては、下ボタン用支持部５と上ボタン用支持部６との距離を調整することにより、被根巻き縫製物１１における、糸１２を水平方向に緊張させた際の、生地と上ボタン９との間の距離に応じて、生地と上ボタン９との距離が異なる被根巻き縫製物１１の根巻きを行うことができる。
【００３１】
また、下ボタン用支持部５が回動自在であるので、下ボタン用支持部５の移動を簡単な構成で行うことができ、下ボタン用支持部５の曲折支持部４の上方への出没を極めて容易に行うことができる。本実施形態においては、上ボタン用支持部６を下ボタン支持部５と一体的に設けたので、上ボタン用支持部６の曲折支持部４の上方への出没も容易であるのは勿論のこと、各ボタン用支持部５，６が一体的に移動するので極めて扱いやすい。
【００３２】
また、下ボタン用支持部５が上方位置と格納位置とに選択的に位置するよう構成したので、下ボタン用支持部５が各位置の中間に定常的に位置することはなく、下ボタン用支持部５の曲折支持部４の上方への出没を的確に行うことができる。尚、本実施形態においては、上ボタン支持部６が下ボタン支持部５と一体的に設けられているので、上ボタン用支持部６の曲折支持部４の上方への出没もまた、的確に行うことができる。
【００３３】
このように、本実施形態の被縫製物支持具１によれば、下ボタン用支持部５を移動させることにより、曲折支持部４による被縫製物２の支持と、下ボタン用支持部６による被根巻き縫製物１１の支持とを選択的に行うことができ、一台のミシン１００で、被縫製物２のすくい縫い及び根巻きに加え、上ボタン９及び下ボタン１０が既に縫製された被根巻き縫製物１１の根巻きをも行うことができる。
【００３４】
これにより、衣服を製造する工場等において、すくい縫い及び根巻きを行って一のボタンを被縫製物に縫い付けるミシンと、上ボタン及び下ボタンが既に縫製された被根巻き縫製物の根巻きのみを行う専用のミシンとを別個に設置する必要はなく、ミシンの共用化を図って製造コストを低減することができるし、工場等にて衣服等を生産する際の自由度を格段に向上することができる。
【００３５】
また、本実施形態の被縫製物支持具１によれば、下ボタン用支持部５が回動自在であるので、下ボタン用支持部５の移動を簡単な操作で行うことができ、取扱等に際して極めて便利である。
また、下ボタン用支持部５が上方位置と格納位置とに選択的に位置するよう構成したので、下ボタン用支持部５の曲折支持部４の上方への出没を的確に行うことができ、実用に際して極めて有利である。
【００３６】
また、本実施形態の被縫製物支持具１によれば、下ボタン用支持部５に加えて上ボタン用支持部６を設け、上ボタン用支持部６にて被根巻き縫製物１１の上ボタン９側を支持するようにしたので、例えば、ミシン１００のチャックが上ボタン９を鉛直状態で保持する機能を有していない場合であっても、被根巻き縫製物１１の根巻き処理を行うことができる。
【００３７】
また、本実施形態の被縫製物支持具１によれば、下ボタン用支持部５と上ボタン用支持部６との調整機構を設け、生地と上ボタン９との距離が異なる被根巻き縫製物１１の根巻きを行うことができるようにしたので、一台のミシン１００で、異なる根巻き形態のボタン付けを行うことができる。すなわち、多品種の衣服等の根巻き等に対応することができ、これによっても、工場等にて衣服等を生産する際の自由度が向上する。
【００３８】
尚、前記実施形態においては、上ボタン支持部６が設けられたものを示したが、図８及び図９に示すように、上ボタン支持部６を設けずともよい。この場合、被根巻き縫製物１１の上ボタン９をミシン１００に設けられたチャック（図示せず）により支持させることにより、被根巻き縫製物１１の根巻きを行うこととなる。
【００３９】
また、前記実施形態においては、下ボタン支持部５が支持具本体３に回動自在に設けられたものを示したが、下ボタン支持部５が支持具本体３に対して平行に移動するものであってもよく、曲折支持部４の上方に出没自在であれば、如何なる構成であってもよいことは勿論である。
【００４０】
また、前記実施形態においては、上ボタン支持部６を下ボタン支持部５に対してスライドさせて各ボタン支持部５，６間の距離を調整するものを示したが、例えば、上ボタン支持部６を下ボタン支持部５に対して脱着して距離を調整するものであってもよいし、その他、具体的な細部構造等についても適宜に変更可能であることは勿論である。
【００４１】
【発明の効果】
以上詳述したように、請求項１記載の発明によれば、下ボタン用支持部を移動させることにより、曲折支持部による被縫製物の支持と、下ボタン用支持部による被根巻き縫製物の支持とを選択的に行うことができ、一台のミシンで、被縫製物のすくい縫い及び根巻きに加え、上ボタン及び下ボタンが既に縫製された被根巻き縫製物の根巻きをも行うことができる。
従って、衣服を製造する工場等において、すくい縫い及び根巻きを行って一のボタンを被縫製物に縫い付けるミシンと、上ボタン及び下ボタンが既に縫製された被根巻き縫製物の根巻きのみを行う専用のミシンとを別個に設置する必要はなく、ミシンの共用化を図って製造コストを低減することができるし、工場等にて衣服等を生産する際の自由度を格段に向上することができる。
