【発明の属する技術分野】
本発明は、自動車のシートカバー等の縫製に使用され、表皮材に２本の玉縁材をその玉縁先端が揃った状態として簡単にミシン縫いすることができる玉縁材縫製用ミシンの被縫製物押さえ装置に関するものである。
【０００２】
【従来の技術】
【特許文献１】
特開平６−１９８０９１号公報
【特許文献２】
特開平５−２３４６６号公報
【０００３】
従来から自動車のシートカバー等の縫製品においては、アクセントを付与して美観を増すために玉縁やシングルステッチ、ダブルステッチ等が採用されており、特に、玉縁は高級感があることから好んで用いられている。この玉縁は芯材を表皮布で包み込んだ玉縁材を表皮材に縫い付けたもので、シートカバーでは表皮材間のエッジ部分に玉縁が位置されてエッジ部分の美観を増すようにしたしたものであるが、従来の自動車用シートカバーにおいては、１本の玉縁材を表皮材間ミシン縫いしたものであるため玉縁による装飾効果には限度があった。ところが、最近では自動車用シートカバーにおいてもさらなる美観と高級感の向上が求められており、これを実現するための一つの方法としては、表皮材間に２本の玉縁材を縫い込み介在させてより装飾効果を高めることが考えられる。しかしながら、従来の玉縁材縫製用ミシンの被縫製物押さえ装置は、一般の工業用ミシンに治具等を装着した例えば特開平６−１９８０９１号公報や特開平５−２３４６６号公報に示されるようなものであって、２本の玉縁材をその玉縁先端が揃った状態となるようにミシン縫いすることのできないものであった。
【０００４】
芯材を表皮布で包み込んだ玉縁材は、合成樹脂を棒状あるいはパイプ状に押し出し成形されたものを芯材としてこれを織布、不織布、合成皮革等からなる表皮布で包み込んで構成されており、このような玉縁材は、芯材を包んでいる表皮布をシートカバー等を構成する２枚の表皮材の間に置かれてまとめて縫製されるものであるが、縫製時に玉縁材がずれやすいという問題があるため、前記した特開平６−１９８０９１号公報には表皮材と玉縁材とを位置決めする縫製ガイド治具が開示されており、また、特開平５−２３４６６号公報には玉縁材を左右いずれの側にも縫い付けることができる玉縁部材押さえ装置が開示されている。
【０００５】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の玉縁材縫製用ミシンの被縫製物押さえ装置は、被縫製物である表皮材と、先端が揃った状態で上下方向に配置された２本の玉縁材とを、送り歯となる下押さえと上押さえとの間に挟んで表皮材に両玉縁材をミシン縫いするようにした玉縁材縫製ミシンの被縫製物押さえ装置であって、前記した下押さえと上押さえの対向位置にそれぞれ玉縁誘導溝を設けるとともに、前記上押さえを内押さえと、内押さえとは別体で、この内押さえの両側に配置した外押さえとからなるものとして、内押さえの下面は２つの押さえ面を有し、これら押さえ面の間には縫い足側の押さえ面を他側の押さえ面より上方とする段差を有するものとし、また、外押さえの下面は２つの押さえ面を有し、これら押さえ面の間には縫い足側の押さえ面を他側の押さえ面より上方とする段差を有するものとし、また、内押さえの他側の押さえ面を、外押さえの他側の押さえ面よりも上方とする段差を有するものとしたことを特徴とするものである。
【０００６】
こうした従来の玉縁材縫製用のミシンにおいても玉縁材供給装置を上下に重ねて設ければ、図８に示すように、上下の表皮材１９及び１６の間に２本の玉縁材１８、１７を供給することができ、その状態で縫製すれば２本の玉縁材１８、１７を各玉縁先端を揃えて縫い付けられることとなるはずであるが、上押さえ１により下押さえ２に押し付けると、図９に示すように、上側の玉縁材１８は上押さえの玉縁誘導溝７に誘導されて位置が安定するものの下側の玉縁材１７は上下から押されて位置が安定せず、両玉縁先端が揃わないため、好ましい美観が得られないという問題があった。
【０００７】
【発明が解決しようとする課題】
本発明は前記のような問題点を解決し、上下の表皮材とともに両玉縁先端が揃うように２本の玉縁材を簡単にミシン縫いできる玉縁材縫製用ミシンを提供するためになされたものである。
【０００８】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の玉縁材縫製用ミシンの被縫製物押さえ装置は、被縫製物である表皮材と、先端が揃った状態で上下方向に配置された２本の玉縁材とを、送り歯となる下押さえと上押さえとの間に挟んで表皮材に両玉縁材をミシン縫いするようにした玉縁材縫製ミシンの被縫製物押さえ装置であって、前記した下押さえと上押さえの対向位置にそれぞれ玉縁誘導溝を設けるとともに、前記上押さえを内押さえと、この内押さえの両側に分割して配置した外押さえとからなるものとして、内押さえの下面は２つの押さえ面を有し、これら押さえ面の間には縫い足側の押さえ面を他側の押さえ面より上方とする段差を有するものとし、また、外押さえの下面は２つの押さえ面を有し、これら押さえ面の間には縫い足側の押さえ面を他側の押さえ面より上方とする段差を有するものとし、また、内押さえの他側の押さえ面を、外押さえの他側の押さえ面よりも上方とする段差を有するものとしたことを特徴とするものである。
【０００９】
【発明の実施の形態】
以下に図面を参照しつつ、本発明の実施形態を説明する。
本発明の玉縁材縫製用ミシンの被縫製物押さえ装置は、その主要部分である上押さえ１と下押さえ２に特徴があり、２個の図示しない玉縁材供給装置を上下に重ねて設けたものであって、他の構成は従来の一般的な１本針の工業用ミシンと同様であるので、これらの部分についての説明は省略する。
図１乃至図３はその特徴がある上押さえ１及び下押さえ２からなる主要部分を前方からみた図であり、図１は上押さえ１が引き上げられた状態、図２は２枚の表皮材１６、１９と玉縁材１７、１８とが供給された状態、図３は上押さえ１が下ろされて縫製される状態をそれぞれ示している。
【００１０】
上押さえ１を引き上げられた状態と、下ろされてばねの弾発力により縫製される表皮材１６、１９及び玉縁材１７、１８を押さえた状態の２つの状態のいずれかにレバーの操作によって切り替える機構が設けてあること、針板３に透孔４を設け、該透孔４から送り歯となっている下押さえ２が露出させてあることは従来のミシンと同様である。上押さえ１は内押さえ５と該内押さえ５の両側に分割して配置した外押さえ６とから構成してあり、内押さええ５は外押さえ６に対して若干移動できるものとすることが好ましい。
【００１１】
内押さえ５の下面には玉縁誘導溝７が設けてあり、内押さえ５の縫い足側には玉縁誘導 溝７に隣接する位置に針孔８が設けてある。内押さえ５の下面の玉縁誘導溝７の両側はそ れぞれ押さえ面９、１０としてあり、押さえ面９と押さえ面１０との間には縫い足側の押さえ面１０を他側の押さえ面９より上方とする段差が設けてある。外押さえ６の下面は押さえ面１１、１２としてあり、内押さえ５の押さえ面９及び１０と同様に、押さえ面１１と押さえ面１２との間に縫い足側の押さえ面１２を他側の押さえ面１１より上方とする段差が設けてある。下押さえ２には針孔８に対向する針孔１３と、玉縁誘導溝７に対向する玉縁誘導溝１４が設けてある。この下押さえ２は玉縁誘導溝１４を設けたことにより表皮材に接する送り歯の有効幅が狭くなるため、従来のものに比べて全体の幅を広くすることが好ましい。
【００１２】
玉縁材１７、１８はテープ状の表皮布を折り曲げて芯材を包み込んだものであり、玉縁材供給装置は表皮布の折り曲げと折り曲げた表皮布による芯材の包み込みを行い、玉縁材として供給するものである。玉縁材供給装置としては例えば特開平６−１９８０９１号公報に示されるような芯材を案内するガイドとその外側の表皮布を案内するガイドとから構成されたもの等が使用でき、こうした玉縁材供給装置を上下２段に重ねて設け、上押さえ１と下押さえ２との間に２本の玉縁材１７、１８を供給するようにしてある。なお、図中１５は針孔８及び１３に挿通されて上下する針である。
【００１３】
このように構成されたものは、上押さえ１と下押さえ２との間に下側の表皮材１６、下側の玉縁材１７、上側の玉縁材１８、上側の表皮材１９を図２に示すように重ねて供給する。そして、レバーを操作して上押さえ１を下ろせば、図３に示すように外押さえ６の押さえ面１２は縫い足側の下側の表皮材１６、下側の玉縁材１７の表皮布、上側の玉縁材１８の表皮布、上側の表皮材１９をまとめて下押さえ２に押し付けることになる。また、内押さえ５の押さえ面１０は同様に下側の表皮材１６、下側の玉縁材１７の表皮布、上側の玉縁材１８の表皮布、上側の表皮材１９を下押さえ２に押し付ける。
【００１４】
このとき、下側の玉縁材１７の芯材が包み込まれている部分と当該部分に接する下側の表皮材１６の部分は玉縁誘導溝１４に収容され、また、上側の玉縁材１８の芯材の包み込まれている部分と当該部分に接する上側の表皮材１９の部分は玉縁誘導溝７に収容されるので安定した状態で保持、誘導され、ここに玉縁誘導溝７及び１４に隣接する位置で針１５が挿通されれば下側の表皮材１６、下側の玉縁材１７の表皮布、上側の玉縁材１８の表皮布及び上側の表皮材１９は正確な位置で縫い付けられることになる。
【００１５】
針１５が上下して縫い付ける一方で、縫い付けられた下側の表皮材１６、下側の玉縁材１７の表皮布、上側の玉縁材１８の表皮布及び上側の表皮材１９は下押さえ２の送り歯により送られるが、下側の玉縁材１７と上側の玉縁材１８はそれぞれ玉縁誘導溝１４及び７によって誘導されるので、下側の玉縁材１７と上側の玉縁材１８とは下側の表皮材１６及び上側の表皮材１９に対し一定の位置に縫い付けられることになる。なお、内押さえ５を外押さえ６に対して若干移動できるようにした場合には、玉縁誘導溝７及び１４により玉縁材１８、１７がよりスムーズに誘導される利点がある。
【００１６】
押さえ面１０及び１２と下押さえ２の間に挟まれるのは下側の表皮材１６、下側の玉縁材１７の２枚の表皮布、上側の玉縁材１８の２枚の表皮布及び上側の表皮材１９であるが、押さえ面９及び１１と下押さえ２の間に挟まれるのは下側の表皮材１６及び表皮材１９であって、下側の玉縁材１７及び上側の玉縁材１８の表皮布の合計４枚分の厚さの差があることになる。押さえ面１０及び１２は押さえ面９及び１１より上方となるように段差が設けてあるので、押さえ面１０及び１２が下側の表皮材１６、下側の玉縁材１７の２枚の表皮布、上側の玉縁材１８の２枚の表皮布及び上側の表皮材１９を下押さえ２に押し付けた状態で押さえ面９、１１が下側の表皮材１６、表皮材１９を下押さえ２に押し付けることができる。
【００１７】
このようにして下側の表皮材１６、下側の玉縁材１７の表皮布、上側の玉縁材１８の表皮布及び上側の表皮材１９は図４に示すように縫い付けられるので、下側の表皮材１６及び上側の表皮材１９を折り返せば、図５に示すように下側の表皮材１６と上側の表皮材１９の接続部分に２本の玉縁材１７、１８がその玉縁先端を上下に揃えて平行に縫い付けられた縫製品が製造されることになる。
【００１８】
【発明の効果】
本発明は前記説明から明らかなように、上押さえ及び下押さえの対向位置にそれぞれ玉縁誘導溝を設けたので、上側の玉縁材及び下側の玉縁材の芯材が包み込まれている部分がともに玉縁誘導溝に誘導されることになる。また、押さえ面に縫い足側を上方とする段差が設けておけば厚さの異なる縫い足側と他側が下押さえに押さえつけられることとなって、２本の玉縁材はずれることなく常に玉縁先端を揃えた状態で縫い付けることができるものとなる。
従って、本発明は従来の玉縁材縫製用ミシンでは不可能であった２本の玉縁材を両玉縁先端を揃えた状態で簡単にミシン縫いできる玉縁材縫製用ミシンの被縫製物押さえ装置として業界に寄与するところ極めて大である。
