Description

【０００１】
【発明の属する技術分野】
この発明は、各種の物品に備えられる絞り紐や引き締め紐などの紐状体に対し、こうした紐状体におけるこうした紐状体が備えられた各種物品から引き出された部分に、その長さ方向に沿って移動可能で、かつ、所望の移動位置でこの紐状体に留め付くように取り付けられて用いられる留め具の改良、および、かかる留め具を含んで構成されるかかる紐状体の留め付け構造に関する。
【０００２】
【従来の技術】
シリンダー状部と、ピストン状部と、このピストン状部を付勢するバネとを備え、バネの付勢に抗してピストン状部を押し込んだ状態において連通し合うシリンダー状部の透孔とピストン状部の貫通孔とに挿し通された締ひもにこの押し込みを解くことによってバネの付勢力により留め付く係止装置として、特許文献１に示されるものがある。
【０００３】
かかる係止装置にあってはまた、ピストン状部の下部辺に突出片が形成されていると共に、この突出片に引ひもの係合孔が設けられており、この係合孔に引ひもの一端を挿通した突出片をバネ内に入れ込ませた後、これをシリンダー状部内に挿入するようにしている。
【０００４】
これにより、引ひもの引っ張りによってもピストン状部をバネの付勢に抗してシリンダー状部内に引き込ませることができ、この引っ張りによっても締ひもに対する係止装置の留め付けの解除が可能となっている。
【０００５】

【０００６】
【発明が解決しようとする課題】
しかるに、特許文献１記載の係止装置にあっては、かかる装置の使用される物品の製造の現場において、この装置自体のアッセンブリーもせざるを得ないものであった。すなわち、かかる装置は、前記係合孔に引ひもの一端を挿通した突出片をバネ内に入れ込ませた後、これをシリンダー状部内に挿入することによって初めてアッセンブリーができるものであるため、かかる装置の使用される物品の製造者などのユーザーにかかる装置のアッセンブリーも委ねざるを得ないものであり、こうしたユーザーに完成品としてかかる装置を提供することができないものであった。
【０００７】
また、かかる装置にあっては、前記引ひもの一端が挿通される突出片が前記バネ内に入れ込まれる構造を採用しているため、かかるバネを小径化し難いものであり、このため装置自体のコンパクト化に限界を有するものであった。
【０００８】
そこでこの発明は、この種の紐状体の留め具、および、この留め具を含んで構成される紐状体の留め付け構造において、留め具を構成する各部材を予め組み合わせた状態から、この留め具を構成する雄部材に対し、緊張させることによりこの雄部材を雌部材内に引き込む向きに移動させて紐状体（特許文献１における締ひもに相当する。）への留め付けを解除させる易操作用紐状体（特許文献１における引ひもに相当する。）を容易かつ適切に接続できるようにすると共に、かかる留め具をできる限りコンパクトに構成できるようにすることを主たる目的とする。
【０００９】
【課題を解決するための手段】
前記目的を達成するために、請求項１記載の発明あっては、紐状体の留め具が以下の（１）〜（８）の構成を備えたものとした。
（１）筒状をなす雌部材と、
（２）この雌部材の筒軸方向に沿って移動可能な状態でこの雌部材内に入れ込まれた雄部材と、
（３）雄部材を、雌部材の開放された筒一端からこの雄部材の操作頭部を突き出させる向きに付勢する付勢部材とを備えていると共に、
（４）雌部材と雄部材とには、付勢部材の付勢に抗した雄部材の所定の押し込み位置において連通し合って、紐状体を雌部材の筒軸方向に交叉する向きにして通し抜けさせる通し穴が設けられており、
（５）このように紐状体を通し抜けさせた状態から雄部材の押し込みを解くことによって付勢部材の付勢により紐状体に留め付け力を作用させる留め具であって、
（６）雄部材は、操作頭部に続いて通し穴の形成された中間部を有し、この中間部に続き筒状をなす付勢部材の収納部を有し、さらに、この収納部の開放端部に左右一対の脚部を有しており、
（７）雌部材には、雄部材の一対の脚部間に位置して雄部材の収納部の内奥部との間で付勢部材を挟み込むこの付勢部材の支持部が形成されており、
（８）しかも、雄部材の一対の脚部にそれぞれ、留め具を使用対象物に係留させるようにこの使用対象物に備え付けられる易操作用紐状体の挿通穴が形成してある。
【００１０】
かかる構成によれば、雄部材の操作頭部側が付勢部材の付勢によって雌部材の筒一端からもっとも突き出されている状態から、この付勢に抗して操作頭部を利用して雄部材を雌部材内に押し込むことにより、雌部材の通し穴と雄部材の通し穴とが紐状体を抵抗なく通し抜け出きるように連通し合った状態を作り出すことができる。そして、この雄部材の押し込み状態において連通し合った雌部材の通し穴と雄部材の通し穴とに紐状体を挿通させることにより、紐状体を雌部材の筒軸方向に交叉する向きして留め具に挿し通すことができる。
【００１１】
このように留め具に紐状体を挿し通した後、雄部材の押し込み操作を止めると、付勢部材の付勢によって雄部材はその通し穴を雌部材の通し穴と連通させ合わせないように、つまり雄部材の通し穴と雌部材の通し穴とを段違いとするように移動されることから、前記のように挿し通された紐状体は段違いとなった通し穴の穴縁部で挟み付けられ、紐状体に対して留め具が留め付けられる。
【００１２】
このように紐状体に留め具が留め付けられた状態は、操作頭部を利用して雄部材を雌部材内に押し込むことにより再び解かれ、このように操作頭部を押し込ませた状態において、紐状体の長さ方向に沿って所望の位置まで留め具を移動させることが可能とされる。所望の位置まで留め具を移動させた後、再び雄部材の押し込み操作を止めることにより、この所望の位置において再び紐状体に留め具を留め付けさせることができる。
【００１３】
また、かかる留め具にあっては、易操作用紐状体の挿通穴が雄部材の脚部に形成されていることから、留め具の使用対象物に備え付けられた易操作用紐状体をこの挿通穴を利用して雄部材に取り付けることができ、この易操作用紐状体の取り付けによってこの易操作用紐状体を介して留め具を使用対象物に係留させるようにすることができる。
【００１４】
そしてこれにより、第一に、この易操作用紐状体を引っ張ることによっても紐状体に対する留め具の留め付け状態を解除させることができる。すなわち、易操作用紐状体は雄部材に対し操作頭部と反対の脚部において取り付けられていることから、この易操作用紐状体を引っ張ることにより、付勢部材の付勢に抗する向きに雄部材を移動させることができ、この移動により紐状体に対する留め具の留め付け状態を解除させることができる。
【００１５】
また、第二に、この易操作用紐状体を緊張させる向きに紐状体を引っ張ることによっても紐状体に対する留め具の留め付け状態を解除させることができる。すなわち、易操作用紐状体は雄部材に対し操作頭部と反対の脚部において取り付けられていることから、この易操作用紐状体を緊張させる向きに紐状体を引っ張ることによっても、付勢部材の付勢に抗する向きに雄部材を移動させることができ、この移動により紐状体に対する留め具の留め付け状態を解除させることができる。
【００１６】
かかる留め具にあっては、付勢部材が雄部材の収納部の内奥部と雌部材の支持部との間に挟み込み状に納められており、易操作用紐状体はこの支持部を間に納めてこの支持部の先に入り込むようになっている雄部材の一対の脚部に形成されている挿通穴に通されるようになっていることから、留め具をアッセンブリーした後に、この留め具を構成する雄部材に易操作用紐状体を適切に取り付けることができる。また、付勢部材の納められている箇所にはこの易操作用紐状体は入り込まないことから、付勢部材をコンパクト化することができ、これにより、留め具全体をコンパクトに構成させることができる。
【００１７】
また、請求項２記載の発明にあっては、請求項１記載の紐状体の留め具における雌部材の支持部によって雌部材の内部空間が二つに仕切られたようになっていると共に、
雄部材の操作頭部の突き出し側と反対の側にある雌部材の筒他端とこの支持部の形成箇所との間にある雌部材の側部における対向位置にそれぞれ、易操作用紐状体の挿通穴が形成してあることを特徴としている。
【００１８】
かかる構成によれば、雌部材の挿通穴を通じて雌部材内に組み込まれている雄部材の一対の脚部に形成された挿通穴に易操作用紐状体を容易に挿し通すことができる。
【００１９】
また、請求項３記載の発明にあっては、請求項２記載の紐状体の留め具における雌部材の挿通穴が少なくとも雌部材の筒軸方向において易操作用紐状体の太さよりも穴幅を広くするように構成してあることを特徴としている。
【００２０】
かかる構成によれば、易操作用紐状体が緊張した場合に、この雌部材の挿通穴の穴幅の範囲内において雄部材を雌部材内に引き込む向きに円滑に移動させることができ、この雄部材の移動によって紐状体と留め具との留め付けを適切に解除させることができる。
【００２１】
また、請求項４記載の発明にあっては、紐状体の留め付け構造が、以下の（１）〜（３）の構成を備えたものとした。
（１）請求項１から請求項３のいずれか１項に記載の紐状体の留め具と、
（２）この留め具の使用対象物に備えられるこの留め具の留め付けられる紐状体と、
（３）雄部材の挿通穴又は雄部材の挿通穴と雌部材の挿通穴とに通されると共に、紐両端を使用対象物に止着された易操作用紐状体とを備えている。
【００２２】
かかる構成によれば、第一に、この易操作用紐状体を引っ張ることによっても紐状体に対する留め具の留め付け状態を解除させることができる。すなわち、易操作用紐状体は雄部材に対し操作頭部と反対の脚部において取り付けられていることから、この易操作用紐状体を引っ張ることにより、付勢部材の付勢に抗する向きに雄部材を移動させることができ、この移動により紐状体に対する留め具の留め付け状態を解除させることができる。
【００２３】
また、第二に、この易操作用紐状体を緊張させる向きに紐状体を引っ張ることによっても紐状体に対する留め具の留め付け状態を解除させることができる。すなわち、易操作用紐状体は雄部材に対し操作頭部と反対の脚部において取り付けられていることから、この易操作用紐状体を緊張させる向きに紐状体を引っ張ることによっても、付勢部材の付勢に抗する向きに雄部材を移動させることができ、この移動により紐状体に対する留め具の留め付け状態を解除させることができる。
【００２４】
【発明の実施の形態】
以下、図１ないし図１６に基づいて、この発明の典型的な実施の形態について説明する。
【００２５】
なお、ここで図１は、実施の形態にかかる留め具Ｔの使用状態の一例および実施の形態にかかる紐状体Ｗの留め付け構造Ｋの一例を示しており、また、図２および図３は、紐状体Ｗに留め具Ｔが留め付けられた状態をそれぞれ示している。また、図４は、紐状体Ｗの留め付けを解いた状態を示している。
【００２６】
また、図５および図６は、かかる留め具Ｔを一部を破断させた状態としてそれぞれ示しており、図５に対して図６は９０度異なる位置からかかる留め具Ｔを視た状態として示している。
【００２７】
また、図７ないし図１０は、留め具Ｔを構成する雌部材１を、図１１ないし図１４は、留め具Ｔを構成する雄部材２を、それぞれ示している。
【００２８】
また、図１５は、留め具Ｔを構成する各部材を分離した状態として、図１６は、これらの要部を断面にした状態として示している。
【００２９】
この実施の形態にかかる紐状体Ｗの留め具Ｔは、かばん類や袋物の開口縁部を巡るように備えられた絞り紐や、衣服のフードの開放部を巡るように備えられた絞り紐や、ウエストバンドとして用いられる引き締め紐、手袋やブーツなどの履き口部を巡るように備えられた絞り紐などの紐状体Ｗに対し、こうした紐状体Ｗにおけるこうした紐状体Ｗが備えられた各種物品から引き出された部分Ｗａに、その長さ方向に沿って移動可能で、かつ、所望の移動位置でこの紐状体Ｗに留め付くように取り付けられて用いられるものである。
【００３０】
また、この実施の形態にかかる紐状体Ｗの留め付け構造Ｋは、かかる紐状体Ｗの留め具Ｔを含んで構成されるものであって、こうした紐状体Ｗにおける各種物品から引き出された部分Ｗａの寸法を、この引き出し部分に対する留め具Ｔの留め付け位置を変えることにより変えて、こうした紐状体Ｗの巡らされた各所物品の開口などを引き絞ったり、開き出させたりするためなどに用いられる構造である。
【００３１】
紐状体Ｗとしては、丸紐、平紐、各種のコードの他、いわゆるテープなどとも称される帯状体などを予定しており、本明細書における紐状体Ｗはこれらをすべて含む概念である。
【００３２】
かかる留め具Ｔは、雌部材１と、雄部材２と、付勢部材３とを備えている。
【００３３】
（雌部材１）
雌部材１は、筒状をなすように構成されている。
【００３４】
図示の例にあっては、かかる雌部材１は、その筒軸に直交する向きの断面において、断面外郭形状および断面内郭形状をいずれも、ほぼ楕円形状とするように構成されている。すなわち、雌部材１は、幅狭側と幅広側とを持った扁平筒状をなすように構成されている。
【００３５】
また、図示の例にあっては、かかる雌部材１の筒一端１０は、完全に解放されており、この筒一端１０からその内部に後述するように雄部材２が入れ込まれるようになっている。
【００３６】
また、この雌部材１内には、後述する雄部材２の一対の脚部２３、２３間に位置して雄部材２の収納部２２の内奥部２２ａとの間で付勢部材３を挟み込むこの付勢部材３の支持部１１が形成されている。
【００３７】
図示の例にあっては、かかる支持部１１は、雌部材１の筒一端１０と筒他端との間にあって、この雌部材１の内部空間を二つに仕切るようにして設けられている。
【００３８】
具体的には、かかる支持部１１は、雌部材１の筒軸に直交する向きの両面を備えると共に、両端をそれぞれ雌部材１の幅狭側の内壁に一体に接合させた細長い板状体として構成されている。
【００３９】
また、かかる支持部１１における長さ方向に沿った縁部の一方と雌部材１の幅広側の内壁の一方との間と、かかる支持部１１における長さ方向に沿った縁部の他方と雌部材１の幅広側の内壁の他方との間にはそれぞれ、支持部１１によっていわば仕切られた雌部材１の内部空間の一方と他方とを連通させる連通部１２が形成されており、雌部材１の前記筒一端から脚部２３の側を先にしてこの雌部材１内に入れ込まれる雄部材２は、この連通部１２、１２の一方に一対の脚部２３、２３の一方を入り込ませ、かつ、この連通部１２、１２の他方に一対の脚部２３、２３の他方を入り込ませるようになっている。
【００４０】
図示の例にあっては、雌部材１の筒他端には、この筒他端から前記支持部１１の全体を覗き込める大きさの細長い開口１３が形成されており、雌部材１をプラスチック材料から射出成型によって形成するようにした場合に、この開口１３を利用して抜き出される型によって支持部１１を成形できるようにしてある。また、図示の例にあっては、支持部１１は、雌部材１の筒他端に臨んだ側において、この支持部１１の端部に等辺の一方を、また、雌部材１の幅狭側の内壁に等辺の他方を、それぞれ一体に接合させた二等辺三角形状をなすサポート板体１４によって、この雌部材１の筒他端に臨んだ側において支えられるようになっている。
【００４１】
かかる雌部材１における幅広側の側部のうち筒一端１０と支持部１１との間にある両側部にそれぞれ、付勢部材３の付勢に抗した雄部材２の所定の押し込み位置においてこの雄部材２に形成された通し穴２４と連通し合って、紐状体Ｗを雌部材１の筒軸方向に交叉する向きにして通し抜けさせる通し穴１５が設けられている。
【００４２】
図示の例では、かかる通し穴１５は、雌部材１の筒軸方向にある側を短寸側とし、かつ、この筒軸に直交する方向にある側を長寸側としたほぼ楕円形の貫通穴として構成されている。
【００４３】
また、図示の例にあっては、かかる雌部材１における幅広側の側部のうち筒他端と支持部１１との間にある両側部にそれぞれ、後述する操作用紐状体Ｗの挿通穴１６が形成してある。
【００４４】
図示の例では、かかる挿通穴１６は、雌部材１の筒軸方向にある側を短寸側とし、かつ、この筒軸に直交する方向にある側を長寸側とした長方形状の貫通穴として構成されている。
【００４５】
（雄部材２）
雄部材２は、前記雌部材１の筒軸方向に沿って移動可能な状態でこの雌部材１内に入れ込まれるように構成されている。
【００４６】
図示の例では、かかる雄部材２は、雌部材１の筒軸方向に沿って移動可能とされる軸状の外観を有するように構成されている。すなわち、図示の例にあっては、雄部材２は、その軸線に直交する向きの断面外郭形状を、雌部材１の前記断面内郭形状に倣った楕円形状であって、この雌部材１の断面内郭形状となる楕円形よりもやや小径の楕円形とするように構成されている。
【００４７】
かかる雄部材２は、操作頭部２０と、中間部２１と、収納部２２と、一対の脚部２３、２３とを、操作頭部２０、中間部２１、収納部２２、脚部２３の順で一体に備えている。そして、雌部材１の筒一端１０から脚部２３の側を先にしてこの雌部材１内に入れ込まれるように構成されている。
【００４８】
操作頭部２０は、後述するように前記付勢部材３の付勢によって雌部材１の筒一端１０から常時外方に突き出すようになっている。
【００４９】
中間部２１に、紐状体Ｗの通し穴２４が形成されている。図示の例では、かかる通し穴２４は、雄部材２の軸線方向にある側を短寸側とし、かつ、この軸線に直交する方向にある側を長寸側とした長方形状の貫通穴として構成されている。
【００５０】
そして、この雄部材２の通し穴２４が雌部材１の通し穴１５に連通し合う位置まで、付勢部材３の付勢に抗して雄部材２を雌部材１内に押し込ませることにより、このように連通し合う通し穴１５、２４を通じて、紐状体Ｗを雌部材１の筒軸方向に交叉する向きにして通し抜けさせることができるようになっている。
【００５１】
なお、図示の例にあっては、中間部２１の通し穴２４における収納部２２側にある穴縁部に、雌部材１内への雄部材２の入れ込みに伴って雌部材１の通し穴１５における筒一端１０側にある穴縁部に掛合される抜け止め突部２５が形成されている。すなわち、図示の例では、この入れ込みに伴ってこの抜け止め突部２５が雌部材１の幅広側の内壁部に押しつけられて主として雌部材１側を一旦弾性変形させた後、この抜け止め突部２５が雌部材１の通し穴１５に入り込んだ雄部材２の入れ込み位置における雌部材１側の弾発によってこの抜け止め突部２５が前記のように掛合されて雌部材１と雄部材２との組み合わせ状態が維持されるようになっている。図示の例では、この抜け止め突部２５によって、付勢部材３の付勢によって雄部材２は雌部材１の筒一端１０から操作頭部２０の側を外方に常時突き出させるが、この抜け止め突部２５が雌部材１の通し穴１５に掛合される位置より先には突き出されないようになっている。（図５）
【００５２】
収納部２２は、付勢部材３を納める筒状をなすように構成されている。図示の例では、かかる収納部２２は、中間部２１に筒一端を一体に接合させると共に、筒他端を開放端部そして開放させた短寸の筒状体として構成されている。
【００５３】
また、左右一対の脚部２３、２３は、かかる収納部２２の開放端部における対向位置からそれぞれ、雄部材２の軸線に沿って突き出している。
【００５４】
図示の例では、中間部２１に筒一端を一体に接合させた筒体の筒他端から中間部２１の側に向けて雄部材２の幅狭側の両側部においてそれぞれ、この筒体を割り欠く割欠き部２６を形成させることにより、前記左右一対の脚部２３、２３を形成させるようにしている。
【００５５】
また、図示の例にあっては、収納部２２の内奥部２２ａ、つまり、この収納部２２と中間部２１との連接箇所における脚部２３の側に向けられた面部のほぼ中央に、この脚部２３の側に向けて突き出す付勢部材３の組み込み用突部２７が形成されている。
【００５６】
また、かかる雄部材２の一対の脚部２３、２３にはそれぞれ、留め具Ｔをその使用対象物Ｍに係留させるようにこの使用対象物Ｍに備え付けられる易操作用紐状体Ｗ’の挿通穴２８が形成してある。
【００５７】
図示の例にあっては、かかる挿通穴２８は、脚部２３の末端部において、雄部材２の軸線に直交する向きに長く延びるように形成されたスリット状をなす貫通穴として構成されている。
【００５８】
図示の例にあっては、雄部材２は収納部２２の筒他端を雌部材１の支持部１１に突き当てさせる位置まで雌部材１内に押し込めるようになっている。（図４）
【００５９】
（付勢部材３）
付勢部材３は、雄部材２を、雌部材１の開放された筒一端１０からこの雄部材２の操作頭部２０を突き出させる向きに常時付勢する構成を備えている。
【００６０】
図示の例では、かかる付勢部材３は、圧縮コイルバネ３０として構成されている。そして、図示の例にあっては、かかるバネ３０の一端からかかるバネ３０の内方に雄部材２の収納部２２の内奥部２２ａに形成された組み込み用突部２７が入れ込まれると共に、このバネ３０の他端が雌部材１の支持部１１におけるこの雌部材１の筒一端１０に向けられた面部によって支持されるようにしてあり、この支持部１１と雄部材２の収納部２２の内奥部２２ａとの間でバネ３０が挟み込まれるようになっている。
【００６１】
（機能）
雄部材２の操作頭部２０側が付勢部材３の付勢によって雌部材１の筒一端１０からもっとも突き出されている状態（図５、図６）から、この付勢に抗して操作頭部２０を利用して雄部材２を雌部材１内に押し込むことにより、雌部材１の通し穴１５と雄部材２の通し穴２４とが紐状体Ｗを抵抗なく通し抜け出きるように連通し合った状態を作り出すことができる。（図４）そして、この雄部材２の押し込み状態において連通し合った雌部材１の通し穴１５と雄部材２の通し穴２４とに紐状体Ｗを挿通させることにより、紐状体Ｗを雌部材１の筒軸方向に交叉する向きして留め具Ｔに挿し通すことができる。
【００６２】
このように留め具Ｔに紐状体Ｗを挿し通した後、雄部材２の押し込み操作を止めると、付勢部材３の付勢によって雄部材２はその通し穴２４を雌部材１の通し穴１５と連通させ合わせないように、つまり雄部材２の通し穴２４と雌部材１の通し穴１５とを段違いとするように移動されることから、前記のように挿し通された紐状体Ｗは段違いとなった通し穴１５、２４の穴縁部で挟み付けられ、紐状体Ｗに対して留め具Ｔが留め付けられる。（図３）
【００６３】
このように紐状体Ｗに留め具Ｔが留め付けられた状態は、操作頭部２０を利用して雄部材２を雌部材１内に押し込むことにより再び解かれ、このように操作頭部２０を押し込ませた状態において、紐状体Ｗの長さ方向に沿って所望の位置まで留め具Ｔを移動させることが可能とされる。所望の位置まで留め具Ｔを移動させた後、再び雄部材２の押し込み操作を止めることにより、この所望の位置において再び紐状体Ｗに留め具Ｔを留め付けさせることができる。
【００６４】
また、かかる留め具Ｔにあっては、易操作用紐状体Ｗ’の挿通穴２８が雄部材２の脚部２３に形成されていることから、留め具Ｔの使用対象物Ｍに備え付けられた易操作用紐状体Ｗ’をこの挿通穴２８を利用して雄部材２に取り付けることができ、この易操作用紐状体Ｗ’の取り付けによってこの易操作用紐状体Ｗ’を介して留め具Ｔを使用対象物Ｍに係留させるようにすることができる。（図１）
【００６５】
そしてこれにより、第一に、この易操作用紐状体Ｗ’を引っ張ることによっても紐状体Ｗに対する留め具Ｔの留め付け状態を解除させることができる。すなわち、易操作用紐状体Ｗ’は雄部材２に対し操作頭部２０と反対の脚部２３において取り付けられていることから、この易操作用紐状体Ｗ’を引っ張ることにより、付勢部材３の付勢に抗する向きに雄部材２を移動させることができ、この移動により紐状体Ｗに対する留め具Ｔの留め付け状態を解除させることができる。
【００６６】
また、第二に、この易操作用紐状体Ｗ’を緊張させる向きに紐状体Ｗを引っ張ることによっても紐状体Ｗに対する留め具Ｔの留め付け状態を解除させることができる。すなわち、易操作用紐状体Ｗ’は雄部材２に対し操作頭部２０と反対の脚部２３において取り付けられていることから、この易操作用紐状体Ｗ’を緊張させる向きに紐状体Ｗを引っ張ることによっても、付勢部材３の付勢に抗する向きに雄部材２を移動させることができ、この移動により紐状体Ｗに対する留め具Ｔの留め付け状態を解除させることができる。
【００６７】
かかる留め具Ｔにあっては、付勢部材３が雄部材２の収納部２２の内奥部２２ａと雌部材１の支持部１１との間に挟み込み状に納められており、易操作用紐状体Ｗ’はこの支持部１１を間に納めてこの支持部１１の先に入り込むようになっている雄部材２の一対の脚部２３、２３に形成されている挿通穴２８に通されるようになっていることから、留め具Ｔをアッセンブリーした後に、この留め具Ｔを構成する雄部材２に易操作用紐状体Ｗ’を適切に取り付けることができる。また、付勢部材３の納められている箇所にはこの易操作用紐状体Ｗ’は入り込まないことから、典型的には、付勢部材３を圧縮コイルバネ３０とした場合にあっては、このバネ３０を必要最小限の太さとすることができ、留め具Ｔ全体をコンパクトに構成させることができる。
【００６８】
具体的には、図示の例にあっては、留め具Ｔを構成する雄部材２の一対の脚部２３、２３に形成された挿通穴２８に帯状をなす易操作用紐状体Ｗ’を挿通させた後、この易操作用紐状体Ｗ’の両端を使用対象物Ｍに縫着などして止着させることにより、この易操作用紐状体Ｗ’を介して使用対象物Ｍに留め具Ｔを係留状に連係させるようにしている。
【００６９】
（その他の特徴）
図示の例にあってはまた、雌部材１の支持部１１によって雌部材１の内部空間が二つに仕切られたようになっていると共に、
雄部材２の操作頭部２０の突き出し側と反対の側にある雌部材１の筒他端とこの支持部１１の形成箇所との間にある雌部材１の側部における対向位置にそれぞれ、易操作用紐状体Ｗ’の挿通穴１６が形成してある。
【００７０】

The assembly of the device must be left to the user such as the manufacturer of the article in which the device is used, and such a device cannot be provided to such a user as a finished product.
[0007]
In addition, in such a device, since a projecting piece through which one end of the drawstring is inserted is inserted into the spring, it is difficult to reduce the diameter of the spring, and thus the device itself. There was a limit to downsizing.
[0008]
In view of this, the present invention provides a fastener for this type of string-like body, and a structure for fastening a string-like body including this fastener, in a state in which the members constituting the fastener are combined in advance. By tightening the male member constituting the fastener, the male member is moved in a direction to be pulled into the female member, and the fastening to the string-like body (corresponding to the string in Patent Document 1) is released. The main object is to make it possible to easily and appropriately connect a string for easy operation (corresponding to a string in Patent Document 1) and to make such a fastener as compact as possible.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the invention according to claim 1, the fastener of the string-like body has the following configurations (1) to (8).
(1) a cylindrical female member;
(2) a male member inserted into the female member in a movable state along the cylindrical axis direction of the female member;

[0071]
In the example shown in the figure, the male member 2 is in the state where the retaining protrusion 25 of the male member 2 is engaged with the hole edge on the cylinder end 10 side of the through hole 15 of the female member 1 (FIG. 5). Since the insertion hole 28 of the female member 1 and the insertion hole 16 of the female member 1 do not communicate with each other, the insertion of the easy-to-operate string-like body W ′ resists the biasing of the biasing member 3. The male member 2 is pushed into a position where the insertion hole 28 of the male member 2 and the insertion hole 16 of the female member 1 communicate with each other.
[0072]
Further, in the illustrated example, the insertion hole 16 of the female member 1 is configured to have a hole width wider than the thickness of the string member W ′ for easy operation at least in the cylinder axis direction of the female member 1. .
[0073]
