【０００１】
【発明の属する技術分野】
本発明は、バインダ本体の背表紙部内面に取り付け、これによって文書類を綴じるために使用する綴金具に関し、特に、ファイル対象紙片のファイリングには支障なく使用できるとともに、バインダ本体又は綴金具の交換、或いはいずれかの廃棄等の必要が生じた場合には、容易に綴金具とバインダ本体とを分離することができるファイル用バインダの綴金具に関するものである。
【０００２】
【従来の技術】
従来より、ファイル用バインダの綴金具に於いては、多くの場合、綴金具とバインダ本体とを、前者の基板のリベット孔を後者の背表紙部のリベット孔に一致させて位置決めし、一致した双方の孔にリベットを挿入し、該リベットを加締めることで固定している。
【０００３】
多くのファイル用バインダの綴金具は、以上のように、バインダ本体の背表紙部内面の所定の位置に確実に固定されている。そのため、用法に従って用いる限りでは非常に丈夫でもあり好都合であるが、このようなファイル用バインダも、長期間の使用による損傷など何らかの理由でいずれ廃棄すべき時期が到来することも避けられず、或いは、対象のファイル用バインダで綴じたファイル対象紙片を綴金具ごとバインダ本体から取り外し、これを別個に保管し、綴金具を取り外したバインダ本体には新たな綴金具再度取り付けたい場合もある。
【０００４】
前者の場合は、ファイル用バインダに於ける綴金具の確実な固定が近時に於ける社会的要請となっている材質毎の分別廃棄に不都合となっている。ファイル用バインダを構成する一方のバインダ本体が紙であるのに対し他方の綴金具は金属であるという具合に通常材質が異なっており、結合したままの廃棄は許されないためである。このため、例えば、マイナスドライバ状の分解器具の先端等を綴金具の基板とバインダ本体の背表紙部との間に挿入して相互を引離そうとしたとしても、かなりの力が必要であり、分解は困難である。
【０００５】
また後者の場合は、バインダ本体及び綴金具のいずれも損傷を生じさせることなく両者を分離する必要があるが、既述のように、これは容易に行うことができない。
【０００６】
そこで、特に前者の問題を解決することを目的として、ファイル用金具（綴金具）の金属基板に鳩目部材の軸部が挿入できる切欠孔を形成し、かつ該切欠孔に該鳩目部材の加締め変形部が係止して抜け止めとなる切欠凸片を内側に向かって突出させたファイル用金具が提案されている（特許文献１）。
【０００７】
ファイル用バインダに、このようなファイル用金具を用いれば、ファイル用バインダとして普通に用いる場合は、鳩目部材の加締め変形部が前記切欠凸片に係止して抜止めされているため、その固定は充分なものであり、該ファイル用金具がバインダ本体から離脱するような問題の生じる虞は殆どない。
【０００８】
他方、廃棄する必要が生じた場合には、鳩目部材の加締め変形部が、前記切欠凸片の突出する位置と反対側に位置することとなるように、該ファイル用金具をバインダ本体の取付面に平行にスライド移動させ、その後、分解器具のマイナスドライバ状の先端を該切欠凸片の下に挿入し、これを引起せば、該鳩目部材は、これを特に破壊するまでもなく、該切欠孔から抜け、該ファイル用金具をバインダ本体から取外すことができるものである。
【０００９】
従って以上のファイル用バインダによれば、廃棄の際にバインダ本体と綴金具（ファイル用金具）との分離をするという目的は達成できることになるが、この場合でも、やはり、マイナスドライバ状の先端を持った分解器具が必要であり、このような廃棄が必要になるのは必ずしもそのような器具を持っているとは限らない需要者に於いてであることを考慮すると、その本来の用法に従って用いるには充分な強度を持つ一方で、廃棄等の必要が生じた際には、特別な分解器具を一切使用することなく、簡単に綴金具とバインダ本体の分離が可能なファイル用バインダが望まれることになる。
【００１０】
また、以上とは別の場合、例えば、先に述べたように、ファイル対象紙片の保管のために綴金具をバインダ本体から取り外し、他の空の綴金具をバインダ本体に再度取り付けるような使用の仕方をしたい場合に関しては、取り外した綴金具に部分的な変形（切欠凸片の変形）が生じるため、その後、これをそれに綴じているファイル用紙片とともに保管するのに必ずしも適切ではないこと、及び取り外し操作でバインダ本体側にも損傷を生じさせるおそれがあり、再使用に不適になるおそれがある等の問題がある。

【発明が解決しようとする課題】
本発明は、以上のような従来のファイル用バインダに於ける問題点に鑑み、一方で、ファイル対象紙片のファリング用としては充分なバインダ本体と綴金具との結合強度を備えるとともに、他方、その廃棄その他のために必要が生じた場合には、特別の器具を用いることなく、各構成部材に損傷を与えることもなく、容易に相互の分離分解が可能なように構成したファイル用バインダの綴金具を提供することを解決の課題とする。
【００１３】
【課題を解決するための手段】
本発明の１は、バインダ本体の背表紙部内面に取り付けられ、相互に対面する一方に綴棒を、他方に該綴棒と嵌脱自在に嵌合する綴管を備えた一対の側板と、該側板を両側に立上げる基板とからなり、上記一対の側板の両下端部が各々上記基板の対応する側部とヒンジ結合すると共に、該二つのヒンジ結合の少なくとも一方が着脱自在なそれである片開き又は両開き構造のファイル用バインダの綴金具に於いて、
該綴金具に、これを前記バインダ本体の背表紙部内面に着脱自在に取り付ける取付手段を構成することとし、
該取付手段を、
前記基板に開口した、前記バインダ本体の背表紙部に開口した複数の取付孔に各対応する複数の結合孔と、
相互に対面する側壁の上端が係止上板で相互に繋がる門型の連結頭部を有し、かつ下端に上記係止上板と平行な鍔体を備えた連結部材であって、前記背表紙部の内面に綴金具の基板を前者の該当する取付孔と後者の該当する結合孔とを相互に一致させつつ当接させた上で、該背表紙部の外面側から各一致して配された取付孔及び結合孔に連結部材の連結頭部を挿入し、各連結頭部の上部を結合孔から突出させ、かつ鍔体上面を取付孔の周囲に当接させる連結部材と、
前記基板の結合孔から突出させた連結頭部の係止上板及び両側壁で形成されるトンネル状空間に基板上面を滑らせて貫通させる挿入片を備えた連結補助片であって、該挿入片の先端部下面及び基部下面を該基板上面に当接させ、かつ該挿入片の後端部上面を上記係止上板下面に当接させて前記鍔体とともに背表紙部及び基板を挟持して、後者を前者に固定保持する連結補助片と、
で構成したファイル用バインダの綴金具である。
【００１４】
前記綴金具は、バインダ本体の背表紙部内面との取付手段に関する部分以外は従来のそれと異ならない。即ち、ファイル対象紙片を綴じる構造は従来の綴金具のそれをそのまま採用することができる。該綴金具の取付対象であるバインダ本体も、その背表紙部に開口した複数の取付孔を除いては、従来のファイル用バインダのそれをそのまま採用できるのは云うまでもない。
【００１５】
前記基板は、一対の側板を片開き又は両開き構造にヒンジ結合するものであり、以上のように、バインダ本体との取付手段に関する部分以外は既存のそれをそのまま採用できるが、側板との結合構造等との関係から、該一対の側板に挟まれた部分の両側に取付板部を延長し、この取付板部に前記結合孔を開口することとするのが適当である。勿論、このようにした場合は、前記バインダ本体の背表紙部には、その適切な位置に上記基板を配置した場合に取付板部の結合孔が位置することとなる部位に対応させて取付孔を形成しておくこととすべきなのは云うまでもない。
【００１６】
前記基板の両側の取付板部に形成する結合孔の数は、該基板の幅に対応して決定するのが適当である。狭い場合はそれぞれ一個で十分であり、広い場合は２個にし、更に広い場合は３個以上とすれば良い。各結合孔の形状は特定のそれに限定されないが、該結合孔に挿入する連結部材の連結頭部との関係から方形に構成するのが適当である。前記バインダ本体の背表紙部に開口する取付孔の形状も同様とする。
【００１７】
前記連結部材の連結頭部の鍔体上面からの高さは、重ね合わせた前記バインダ本体の背表紙部と前記基板の厚みを僅かに越える程度とする。より正確には、重ね合わせた背表紙部と基板の取付孔と結合孔に前者から該連結頭部を挿入した場合に、該基板の上部に突出した係止上板の下方の空間に連結補助片の挿入片をタイトに挿入可能なだけの高さとする。また該連結頭部の平面から見た縦横の寸法は、該基板の結合孔及び背表紙部の取付孔の縦横の寸法とほぼ一致するように構成し、前者を後二者に挿入した場合に、背表紙部に重ねた基板が相互の平行方向に容易に動かないようにするのが適当である。
【００１８】
前記連結部材の鍔体は、既述のように、両側壁の下端から前記係止上板と平行に張り出させるものであるが、両側方ばかりでなく、連結頭部全体を囲むように構成するのが適当である。
【００１９】
前記連結補助片は、前記のように、基板の結合孔上に突出した連結頭部のトンネル状空間にその挿入片を挿入して、その先端部下面及び基部下面を基板上面に当接させ、該連結部材の鍔体とともに、該基板及びバインダ本体の背表紙部を挟持して前者の後者への取付状態を固定するものであり、そのために十分な強度を持つ必要がある。強度確保のために必要に応じて、縦横方向に突条を形成することができる。
【００２０】
したがって本発明の１のファイル用バインダの綴金具によれば、綴金具のバインダ本体への取り付け及び取り外しを特別の器具を用いることなく容易に行え、かつその取付強度は、従来のファイル用バインダに於けるそれと同様に、その用法に従ってファイル用紙片のファイリングに使用する限り全く問題のない十分なものとなるものである。またその用法が従来のそれと同様であるのも云うまでもない。
【００２１】
綴金具のバインダ本体の背表紙部への取付は次の通り行うことができる。
綴金具の基板をバインダ本体の背表紙部内面に配置する。基板は側板を取り付けた状態で背表紙部内面に配置しても、背表紙部内面に固定してから取り付けることとしても良い。また基板はその各結合孔を背表紙部の取付孔に一致させつつ該背表紙部の内面に配置すべきであるのは云うまでもない。
【００２２】
次いで、背表紙部の外面側から各一致して位置する取付孔及び結合孔に前記連結部材の連結頭部を挿入する。この挿入は、該連結部材の鍔体上面が取付孔の周囲、即ち、背表紙部の外面に当接するまで行う。
【００２３】
この後、以上のようにして、各一致した位置にある取付孔と結合孔ごとに挿入し、その上部が各結合孔から僅かに突出した連結部材の連結頭部に各々前記連結補助片をセットする。該連結補助片は、その挿入片を基板上を滑らせながら連結頭部の係止上板及び両側壁で形成されるトンネル状空間に貫通させ、その先端部下面及び基部下面を該基板上面にタイトに当接させ、かつ該挿入片の後端部上面を上記係止上板の下面にタイトに当接させるものである。
【００２４】
こうして全取付孔と結合孔に連結部材及び連結補助片をセットすると、該各連結部材の鍔体と連結補助片とによって、基板とバインダ本体の背表紙部とが強く挟持されて固定され、綴金具がバインダ本体の背表紙部内面に固定された状態となる。
【００２５】
またこのようにしてバインダ本体の背表紙部内面に固定されている綴金具は、連結部材の連結頭部のトンネル状空間に挿入してある連結補助片の挿入片を抜き取り、かつ該連結部材の連結頭部を背表紙部の取付孔及び基板の結合孔から抜き取れば、それだけで簡単にバインダ本体の背表紙部内面から取り外すことができる。
【００２６】
従って本発明の１のファイル用バインダの綴金具によれば、ファイル対象紙片のファリング用としては充分なバインダ本体と綴金具との結合強度を備えるものでありながら、その廃棄その他のために必要が生じた場合には、特別の器具を用いることなく、各構成部材に損傷を与えることもなく、極めて簡単に相互の分離分解が可能であり、また逆に綴金具とバインダ本体の結合組み立ても極めて簡単に行うことができるものである。
【００２７】
本発明の２は、本発明の１のファイル用バインダの綴金具に於いて、前記連結補助片に於ける挿入片の少なくとも前記後端部に上方に膨らむ突条であって、該挿入片を前記連結頭部のトンネル状空間に貫通させた際に、その上部が前記係止上板の下面に圧接状態となる突条を形成したものである。
【００２８】
従って本発明の２のファイル用バインダの綴金具によれば、前記のように、綴金具をバインダ本体の背表紙部内面に固定する場合に、前記連結補助片の挿入片の前記連結頭部のトンネル状空間への挿入がスムーズに行われるとともに、挿入後は該トンネル状空間中により確実に固定され、容易に抜けなくなるので、綴金具のバインダ本体の背表紙部への取付がより安定した確実なものとなる。
【００２９】
本発明の３は、本発明の１又は２のファイル用バインダの綴金具に置いて、前記連結補助片の基部から前記挿入片と平行に係止孔を備えた係止片を延長し、該挿入片を前記連結頭部のトンネル状空間に貫通させた際に、その該係止孔が前記基板に膨出させた係止突部に着脱自在に係止するように構成したものである。
【００３０】
前記係止突部は、基板の該当する部位の幅等を考慮し、狭い場合は半円球状の突部に構成し、適当な広さを持っている場合は適切な長さを持った突条に構成することができる。その場合、前記係止片に開口する係止孔も対応する形状に形成すべきなのは云うまでもない。
【００３１】
従って本発明の３のファイル用バインダの綴金具によれば、前記のように、綴金具をバインダ本体の背表紙部内面に固定した場合に、前記係止片の係止孔が基板に膨出した係止突部に外嵌することになるため、該綴金具の固定がより確実なものとなる。
【００３２】
本発明の４は、本発明の１、２又は３のファイル用バインダの綴金具に於いて、前記結合孔の周縁の一以上の部位に、基板を前記バインダ本体の背表紙部に前者の結合孔と後者の取付孔を一致させつつ当接させた際に、後者の取付孔の周縁内端に当接して該基板の位置決めをするための位置決め片を垂下構成したものである。
【００３３】
従って本発明の４のファイル用バインダの綴金具によれば、前記のように、綴金具をバインダ本体の背表紙部内面に固定する場合に、背表紙部内面に基板を位置決めすると、結合孔のに構成した位置決め片が取付孔の周縁の対応する部位に当接してその位置決め状態を保持するため、引き続く連結頭部の取付孔及び結合孔への挿入がよりスムーズに行われうるものとなり、更に綴金具のバインダ本体の背表紙部内面に固定後には、綴金具の背表紙部の内面と平行な平面に沿った動きを確実に防止することができるものとなる。
【００３４】
【発明の実施の形態】
本発明の実施の形態を、図面を参照しつつ実施例により詳細に説明する。
【００３５】
＜実施例１＞
実施例１の綴金具１は、図２及び図５（ａ）に示すように、基板２と、その基板本体２０の両側に相互に対面状態に立ち上げられる一対の側板３、４とで構成され、一方の側板３の両側部からは各々綴棒３ａが、他方の側板４の両側部からは各々綴管４ａが相互に対応する位置関係で突出構成され、相互に対応する位置関係にある綴棒３ａと綴管４ａとは、両側板３、４が対面状態にあるとき、嵌脱自在に嵌合しうるようになっている。
【００３６】
また側板３、４の各下端部には、図２及び図６（ａ）に示すように、ヒンジピン３ｂ、４ｂを構成し、基板本体２０の対応する両側部に構成したヒンジ管部２２に着脱自在にヒンジ結合する。
【００３７】
前記基板２は、図２、図５、図６（ｂ）及び図７に示すように、その中央部に位置する前記基板本体２０と、その長さ方向両端部に延長状態に形成した脚板部（取付板部）２１とで構成し、前記ヒンジ管部２２は、前記のように、基板本体２０の両側部に構成する。また両端部の脚板部２１、２１には綴金具１をバインダ本体８の背表紙部８２に取り付けるための取付手段を構成する。
【００３８】
前記ヒンジ管部２２は、図２、図６（ｂ）及び図７に示すように、基板本体２０の両側部から各々側方に突出させた二つのＬ型下部支持片２２ａ、２２ａとその上に進退自在に進出している逆Ｖ型の可動抱え片２２ｂ、２２ｂとからなり、該可動抱え片２２ｂ、２２ｂは、これと一体に構成されている進退操作片２２ｃによって後退操作されうるようになっている。また該可動抱え片２２ｂ、２２ｂは、該進退操作片２２ｃとともに、バネ７によって進出方向の作用力が与えられている。
【００３９】
前記Ｌ型下部支持片２２ａ、２２ａは、側面から見てＬ型に構成された部材であり、他方、前記可動抱え片２２ｂ、２２ｂは、同様に側面から見て逆Ｖ型に構成された部材であって、図６（ｂ）に示すような後者の進出状態では、後者が前者の上面に対面状態になっており、該Ｌ型下部支持片２２ａ、２２ａの上面と可動抱え片２２ｂ、２２ｂの下面との間に生じた管状の空間で前記側板３（４）下端部のヒンジピン３ｂ、３ｂ（４ｂ、４ｂ）を回動自在に支持しうるようになっている。
【００４０】
またこのようなヒンジ管部２２によるヒンジピン３ｂ、３ｂ又は４ｂ、４ｂの支持は、前記進退操作片２２ｃを基板本体２０の内方に押し込むように操作すると、これに伴って前記可動抱え片２２ｂ、２２ｂも後退して解放されることになる。このとき、対応する側板３（４）を引き上げれば、その下端部のヒンジピン３ｂ、３ｂ（４ｂ、４ｂ）は前記Ｌ型下部支持片２２ａ、２２ａの上面から浮上し、ヒンジ管部２２から完全に離脱したことになる。この後、前記進退操作片２２ｃの進出を許容すれば、前記バネ７の作用により、同時に前記可動抱え片２２ｂ、２２ｂも進出し、前記状態に復帰するようになっている。
【００４１】
ヒンジピン３ｂ、３ｂ（４ｂ、４ｂ）のヒンジ管２２への結合は、前記綴棒３ａ、３ａと綴管４ａ、４ａとの嵌合状態の側板３（４）を下降させ、その下端のヒンジピン３ｂ、３ｂ（４ｂ、４ｂ）を前記Ｌ型下部支持片２２ａ、２２ａの外端立ち上がり部分と前記可動抱え片２２ｂ、２２ｂの外端側斜面との間に挿入しつつ押し下げることで行うことができる。これによって可動抱え片２２ｂ、２２ｂが後退し、該ヒンジピン３ｂ、３ｂ（４ｂ、４ｂ）が該Ｌ型下部支持片２２ａ、２２ａの上面に当接する程度に下降した時点で、また該可動抱え片２２ｂ、２２ｂが復帰し、前記したように、該Ｌ型下部支持片２２ａ、２２ａの上面と可動抱え片２２ｂ、２２ｂの下面との間に生じた管状の空間でヒンジピン３ｂ、３ｂ（４ｂ、４ｂ）が支持されることになるわけである。
【００４２】
前記取付手段、即ち、綴金具１をバインダ本体８の背表紙部８２に取り付けるための取付手段は、前記基板本体２０の長さ方向両端部から延長した脚板部２１、２１と、これらに開口した結合孔２１ａ、２１ａ…であって、バインダ本体８の背表紙部８２に開口した複数の取付孔８２ａ、８２ａ…に対応させて開口した結合孔２１ａ、２１ａ…と、連結部材５と、連結補助片６とで構成したものである。
【００４３】
前記結合孔２１ａは、図５（ａ）に示すように、各脚板部２１、２１にそれぞれ二個ずつ開口する。二個の結合孔２１ａ、２１ａの配列は基板２の長さ方向に直交する向きとする。また各結合孔２１ａ、２１ａ…は、その平面から見た形状を前記連結部材５の連結頭部５ａの平面形状に一致する方形とし、その四辺の内、基板２の長さ方向から見て前後の辺に各々位置決め片２１ｂ、２１ｂを垂下構成する。既に述べ、かつ図５（ｂ）に示すように、バインダ本体８の背表紙部８２には、基板２をその内面の所定の位置に配した場合にその両脚板部２１、２１の結合孔２１ａ、２１ａが位置することとなる部位に対応させて、同様の方形の取付孔８２ａ、８２ａ…が開口してあるものとする。
【００４４】
前記連結部材５は、図５（ｃ）に示すように、門型に立ち上がる連結頭部５ａと鍔体５ｂとで構成されるものである。上記連結頭部５ａは、鍔体５ｂから相互に対面状態に立ち上がる二つの側壁とその上端間を結合する係止上板とで構成され、その鍔体５ｂの上面からの高さは、バインダ本体８の背表紙部８２の厚み及び脚板部２１の厚みを加算した高さを僅かに越え、前記連結補助片６の後記挿入片６ｂをタイトに挿入できるだけの高さとする。
【００４５】
なお前記連結頭部５ａの係止上板の前後辺には、図５（ｃ）に示すように、該連結頭部５ａを前記取付孔８２ａ及び結合孔２１ａに挿入する場合に、該結合孔２１ａに形成してある位置決め片２１ｂ、２１ｂがその挿入を妨げないように、対応する切欠部５ｃ、５ｃを形成してある。
【００４６】
前記連結補助片６は、図３（ａ）及び図４に示すように、基部６ａの両側から平行に延長する二本の挿入片６ｂ、６ｂと、基部６ａの中央から同様に平行に延長する係止片６ｃとで構成したものである。
【００４７】
前記挿入片６ｂ、６ｂは、図３（ａ）及び図４に示すように、その長さ方向両側に沿って突条を形成し、かつ基部６ａにもその長さ方向に沿って突条を形成し、それぞれ補強を図ったものである。
【００４８】
前記係止片６ｃの先端には、後述するように、連結補助片６を取付状態から取り外す際に使用する立ち上げ片６ｄを形成し、かつ先端近傍に係止長溝６ｅを開口し、連結補助片６を取付状態にした場合に、脚板部２１の該当する部位に膨出させた係止突条２１ｃに該係止長溝６ｅが外嵌結合するようにする。
【００４９】
以上の綴金具の全ての構成要素は金属で構成されている。
【００５０】
したがってこの実施例１のファイル用バインダの綴金具によれば、綴金具１のバインダ本体８への取り付け及び取り外しを特別の器具を用いることなく容易に行え、かつその取付強度は、従来のファイル用バインダに於けるそれと同様に、その用法に従ってファイル用紙片のファイリングに使用する限り全く問題のない十分なものとなる。その用法は、云うまでもなく、従来のそれと同様である。
【００５１】
綴金具１のバインダ本体８の背表紙部８２への取り付けは次の通り行うことができる。
綴金具１の基板２をバインダ本体８の背表紙部８２内面に配置する。基板２は、その基板本体２０から側板３、４を取り外した状態で背表紙部８２内面に配置する。勿論、側板３、４は取り付けた状態のままで行っても良い。両脚板部２１の各結合孔２１ａ、２１ａを該背表紙部８２の取付孔８２ａ、８２ａ…に一致させつつ配置するのはいうまでもない。こうして正確に各結合孔２１ａ、２１ａ…を対応する取付孔８２ａに一致させると、前者の各々の前後辺に形成してある位置決め片２１ｂ、２１ｂが各対応する取付孔８２ａの前後辺の内面に当接して相互を確実に位置決め固定するようになる。
【００５２】
次いで、バインダ本体８の背表紙部８２の外面側から各一致して位置する取付孔８２ａ及び結合孔２１ａに前記連結部材５の連結頭部５ａを挿入する。この挿入は、図３（ｂ）、（ｃ）に示すように、該連結部材５の鍔体５ｂの上面が取付孔８２ａの周囲、即ち、該当する背表紙部８２の外面部分に当接するまで行う。当然、これは各一致して位置している全取付孔８２ａ及び結合孔２１ａについて行う。
【００５３】
この後、以上のようにして挿入されて、図４に示すように、各脚板部２１の両結合孔２１ａ、２１ａの上部に各々僅かに突出した連結部材５の連結頭部５ａに前記連結補助片６をセットする。該連結補助片６は、その二つの挿入片６ｂ、６ｂを基板２の脚板部２１上を滑らせながら該両連結頭部５ａ、５ａの係止上板及び両側壁で形成されるトンネル状空間に貫通させ、図３（ａ）、（ｂ）、（ｃ）に示すように、その各先端部下面及び各基部下面を該脚板部２１上面にタイトに当接させ、かつ該両挿入片６ｂ、６ｂの後端部上面の両突条を上記各係止上板の下面にタイトに当接させる。
【００５４】
このように連結補助片６の二つの挿入片６ｂ、６ｂを脚板部２１上を滑らせながら連結部材５、５の各連結頭部５ａに挿入貫通させると、同時に、該挿入片６ｂ、６ｂの間にこれらと平行に形成してある係止片６ｃも同方向に摺動進行し、その先端近傍に形成してある係止長溝６ｅに該脚板部２１に膨出形成してある係止突条２１ｃが嵌合係止し、該連結補助片６のその状態を固定保持する。
【００５５】
こうして全取付孔８２ａ、８２ａ…と結合孔２１ａ、２１ａ…に連結部材５及び連結補助片６をセットすると、基板２の脚板部２１、２１がバインダ本体８の背表紙部８２内面に固定されたことになる。この後、基板本体２０の両側部に、前記したように、両側板３、４を取り付け、これにより綴金具１のバインダ本体８の所定部への取付固定は完了である。
【００５６】
こうして綴金具１が組み込まれたファイル用バインダは、この後、云うまでもなく、その用法に従ってファイル対象紙片のファイリングに使用できる。またその用法は、一般的なこの種のそれと同様である。
【００５７】

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device that is attached to the inner surface of a spine portion of a binder main body and is used for binding documents by using the binding device. Also, the present invention relates to a binder for a file binder that can easily separate the binding from the binder main body when any disposal or the like becomes necessary.
[0002]
[Prior art]
Conventionally, in the binder of the file binder, in many cases, the binding and the binder main body are positioned by aligning the rivet holes of the former substrate with the rivet holes of the spine portion of the latter, and matching the positions. A rivet is inserted into both holes, and the rivet is fixed by caulking.
[0003]
As described above, the fasteners of many file binders are securely fixed at predetermined positions on the inner surface of the spine of the binder body. Therefore, it is very robust and convenient as long as it is used in accordance with the usage.However, it is inevitable that such a file binder will eventually be discarded for some reason such as damage due to long-term use, or In some cases, it may be desired to remove the file target paper piece bound with the target file binder from the binder body together with the binding, store it separately, and attach a new binding again to the binder body from which the binding has been removed.
[0004]
In the case of the former, it is inconvenient to separate and discard materials for each material, which has recently become a social demand, because the fixing of the metal fittings in the file binder is required. This is because one binder main body constituting the file binder is made of paper and the other metal fastener is made of metal, so that the material of the binder is usually different. For this reason, even if, for example, the tip of a disassembly tool in the form of a flathead screwdriver is inserted between the binding board and the spine of the binder body to separate them from each other, considerable force is required. Disassembly is difficult.
[0005]
In the latter case, it is necessary to separate both the binder main body and the binding metal without causing damage, but as described above, this cannot be easily performed.
[0006]
Therefore, in order to solve the former problem in particular, a notch hole into which the shaft portion of the eyelet member can be inserted is formed in the metal substrate of the metal fitting (binder) for file, and the eyelet member is crimped into the notch hole. A metal fitting for a file has been proposed in which a notched convex piece that is locked by a deformed portion to prevent it from falling out projects inward (Patent Document 1).
[0007]
If such a file metal fitting is used for the file binder, the caulking deformed portion of the eyelet member is locked to the notch convex piece and is prevented from being pulled out when normally used as a file binder. The fixing is sufficient, and there is almost no possibility that a problem that the metal fitting for the file detaches from the binder main body occurs.
[0008]
On the other hand, when it is necessary to dispose the file fitting, the file metal fitting is attached to the binder main body so that the crimping deformed portion of the eyelet member is located on the opposite side to the position where the notched convex piece projects. Slide in parallel to the plane, and then insert the minus driver-like tip of the disassembly tool below the notch and raise it, so that the eyelet member does not particularly break it, The file fitting can be removed from the cutout hole and the file fitting can be removed from the binder main body.
[0009]
Therefore, according to the above-mentioned file binder, the purpose of separating the binder body and the binding (file fitting) at the time of disposal can be achieved, but in this case, the tip of the minus screwdriver is still used. It is necessary to use disassembly equipment, and it is necessary to dispose of such equipment at the customer who does not necessarily have such equipment. It is desirable to have a file binder that has sufficient strength, but can be easily separated from the binder and the binder body without using any special disassembly device when it becomes necessary to dispose. Will be.
[0010]
In another case, for example, as described above, use may be made such that the fastener is removed from the binder body for storage of the paper sheet to be filed and another empty fastener is reattached to the binder body. When it is desired to do so, it is not always appropriate to store it together with the file paper pieces bound to it, since partial deformation (deformation of notched convex pieces) occurs in the removed metal fittings, and There is a problem that the removal operation may cause damage to the binder main body side and may be unsuitable for reuse.

[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned problems in the conventional file binder, and has, on the one hand, a sufficient bonding strength between the binder body and the binding metal for the purpose of filed paper sheet falling, and, on the other hand, If it becomes necessary to dispose of the file binder, use a file binder that can be easily separated and disassembled without using special equipment and without damaging each component. It is an object of the present invention to provide a metal fitting.
[0013]
[Means for Solving the Problems]
A first aspect of the present invention is a pair of side plates provided with an inner surface of a spine portion of a binder main body, which has a binding bar on one side facing each other and a binding tube fitted on the other side so as to be removably fitted with the binding bar, A strip comprising a substrate having the side plates raised on both sides, wherein both lower end portions of the pair of side plates are hinged to corresponding side portions of the substrate, and at least one of the two hinge connections is detachable. In the binder of the file binder of the opening or double opening structure,
An attachment means for detachably attaching the binding to the inner surface of the spine portion of the binder body,
The mounting means,
A plurality of coupling holes respectively corresponding to a plurality of mounting holes opened in the spine of the binder body, which are opened in the substrate,
A connecting member having a gate-shaped connecting head connected to each other by a locking upper plate at an upper end of the side wall facing each other, and a flange body at a lower end parallel to the locking upper plate; The board of the metal fastener is brought into contact with the inner surface of the cover while the corresponding mounting holes of the former and the corresponding coupling holes of the latter are aligned with each other, and are then aligned from the outer surface side of the spine. A connecting member that inserts the connecting head of the connecting member into the mounting hole and the connecting hole, protrudes the upper portion of each connecting head from the connecting hole, and abuts the upper surface of the flange body around the mounting hole,
A connection auxiliary piece having an insertion piece which slides and penetrates the upper surface of the substrate into a tunnel-like space formed by the upper plate and the both side walls of the connection head protruding from the coupling hole of the substrate; The tip lower surface and the base lower surface of the piece are brought into contact with the upper surface of the board, and the rear end upper surface of the insert is brought into contact with the lower surface of the locking upper plate to hold the spine cover and the board together with the flange. A connecting auxiliary piece for fixing and holding the latter to the former,
It is a metal binder of the file binder constituted by.
[0014]
The above-mentioned metal fitting is not different from that of the related art except for a portion relating to a means for attaching to the inner surface of the spine portion of the binder body. That is, the structure for binding the file-target paper pieces can employ the conventional binding device as it is. It goes without saying that the binder main body to which the metal fittings are to be attached can also adopt that of the conventional file binder as it is, except for a plurality of attachment holes opened in the spine.
[0015]
The above-mentioned substrate hinges a pair of side plates to a one-sided or double-sided structure, and as described above, the existing one can be used as it is, except for the part relating to the means for attaching to the binder body, but the connection structure with the side plate In view of the above, it is appropriate to extend the mounting plate on both sides of the portion sandwiched between the pair of side plates, and to open the coupling hole in the mounting plate. Of course, in this case, the spine portion of the binder main body has a mounting hole corresponding to a portion where the coupling hole of the mounting plate portion is to be located when the substrate is disposed at an appropriate position. Needless to say, it should be formed.
[0016]
The number of coupling holes formed in the mounting plate portions on both sides of the substrate is suitably determined according to the width of the substrate. One is sufficient for each narrow case, two for a wide range, and three or more for a wider range. The shape of each coupling hole is not limited to a specific one, but it is appropriate that the coupling hole is formed in a rectangular shape in relation to the coupling head of the coupling member inserted into the coupling hole. The same applies to the shape of the mounting hole opened in the spine of the binder body.
[0017]
The height of the connecting head of the connecting member from the upper surface of the flange body is set to slightly exceed the thickness of the spine portion of the binder body and the substrate that are superimposed. More precisely, when the connection head is inserted from the former into the mounting hole and the coupling hole of the superimposed spine and the board, the connection assistance is provided in the space below the locking upper plate protruding above the board. The height of the inserted piece should be such that it can be inserted tightly. Also, the vertical and horizontal dimensions of the connecting head as viewed from the plane are configured to substantially match the vertical and horizontal dimensions of the mounting hole of the board and the mounting hole of the spine, and when the former is inserted into the latter two. It is appropriate that the substrates superimposed on the spine do not move easily in the direction parallel to each other.
[0018]
As described above, the collar body of the connecting member projects from the lower ends of both side walls in parallel with the locking upper plate, but is configured to surround not only both sides but the entire connecting head. It is appropriate to do.
[0019]
The connection auxiliary piece, as described above, inserts the insertion piece into the tunnel-like space of the connection head protruding above the coupling hole of the board, and abuts the lower surface of the distal end portion and the lower surface of the base portion on the upper surface of the substrate, The substrate and the spine portion of the binder body are sandwiched together with the flange of the connecting member to fix the former mounting state to the latter, and therefore it is necessary to have sufficient strength. Protrusions can be formed in the vertical and horizontal directions as necessary to ensure strength.
[0020]
Therefore, according to the file binder of the present invention, it is possible to easily attach and detach the binding to and from the binder main body without using any special device, and the attachment strength is equal to that of the conventional file binder. As well as in its use, it will be satisfactory without any problems as long as it is used for filing file paper sheets according to its usage. Needless to say, the usage is the same as the conventional one.
[0021]
Attachment of the binder to the spine of the binder body can be performed as follows.
The substrate of the binding is placed on the inner surface of the spine of the binder body. The substrate may be disposed on the inner surface of the spine portion with the side plate attached, or may be fixed to the inner surface of the spine portion before mounting. Needless to say, the substrate should be arranged on the inner surface of the spine, with each of the coupling holes corresponding to the mounting hole of the spine.
[0022]
Next, the connecting head of the connecting member is inserted into the mounting holes and the connecting holes that are positioned in correspondence with each other from the outer surface side of the spine. This insertion is performed until the upper surface of the collar body of the connecting member comes into contact with the periphery of the mounting hole, that is, the outer surface of the spine.
[0023]
After that, as described above, each of the connection assisting pieces is inserted into each of the mounting holes and the coupling holes at the corresponding positions, and the connection auxiliary pieces are respectively set on the coupling heads of the coupling members whose upper portions slightly protrude from the respective coupling holes. I do. The connection assisting piece slides the insertion piece over the board and penetrates into the tunnel-like space formed by the locking upper plate and both side walls of the connection head, and the lower end of the tip and the lower face of the base are connected to the upper face of the board. A tight contact is made, and the upper surface of the rear end portion of the insertion piece is brought into tight contact with the lower surface of the locking upper plate.
[0024]
When the connecting member and the connecting auxiliary piece are set in all of the mounting holes and the connecting holes in this manner, the substrate and the spine portion of the binder body are strongly sandwiched and fixed by the flange body and the connecting auxiliary piece of each connecting member, and the binding is performed. The metal fitting is fixed to the inner surface of the spine of the binder body.
[0025]
Further, in this manner, the fastener fixed to the inner surface of the spine portion of the binder body removes the insertion piece of the connection auxiliary piece inserted into the tunnel-like space of the connection head of the connection member, and The connection head can be easily removed from the inner surface of the spine portion of the binder body by pulling it out from the mounting hole of the spine portion and the coupling hole of the substrate.
[0026]
Therefore, according to the first embodiment of the present invention, the binder for a file binder has sufficient bonding strength between the binder main body and the binder for the purpose of filed paper sheet falling, but is necessary for disposal and other purposes. In the case of occurrence, it is possible to separate and disassemble each other very easily without using special tools and without damaging each component, and conversely, the joint assembly of the binding and the binder body can also be performed. It can be done very easily.
[0027]
According to a second aspect of the present invention, in the metal binder for a file binder according to the first aspect of the present invention, at least the rear end portion of the insertion piece of the connection auxiliary piece is a ridge that bulges upward, and the insertion piece is When it penetrates into the tunnel-like space of the connecting head, the upper part is formed with a ridge that comes into pressure contact with the lower surface of the locking upper plate.
[0028]
Therefore, according to the second embodiment of the binder for a file binder according to the present invention, as described above, when the binding is fixed to the inner surface of the spine portion of the binder body, the connecting head of the connecting piece of the connecting auxiliary piece is used. Insertion into the tunnel-like space is performed smoothly, and after insertion, it is more securely fixed in the tunnel-like space and does not easily come off, so that the attachment of the binding body to the spine of the binder body is more stable and reliable. It becomes something.
[0029]
According to a third aspect of the present invention, a locking piece provided with a locking hole is extended from the base of the connection assisting piece in parallel with the insertion piece, by placing the binding piece on the file binder of one or two of the present invention, When the insertion piece is passed through the tunnel-like space of the connecting head, the locking hole is detachably locked to a locking projection bulged on the substrate.
[0030]
In consideration of the width of the corresponding portion of the substrate, the locking projection is configured as a semicircular projection when narrow, and a projection having an appropriate length when it has an appropriate width. Articles can be configured. In this case, it is needless to say that the locking hole opened in the locking piece should also be formed in a corresponding shape.
[0031]
Therefore, according to the file binder of the third aspect of the present invention, as described above, when the binding is fixed to the inner surface of the spine of the binder body, the locking holes of the locking pieces protrude from the substrate. Since the fitting is externally fitted to the locking projection, the fixing of the metal fitting is more reliable.
[0032]
According to a fourth aspect of the present invention, in the metal binder for a file binder according to the first, second or third aspect of the present invention, the substrate is bonded to the spine or back cover of the binder body at one or more portions of the periphery of the bonding hole. When the hole and the mounting hole of the latter are brought into contact while being aligned with each other, a positioning piece for positioning the substrate by abutting on the inner edge of the peripheral edge of the mounting hole of the latter is formed.
[0033]
Therefore, according to the binding device for the file binder of the fourth aspect of the present invention, as described above, when the binding device is fixed to the inner surface of the spine portion of the binder main body, when the substrate is positioned on the inner surface of the spine portion, the bonding hole of the binding hole is formed. Since the positioning piece configured as described above abuts against the corresponding portion of the periphery of the mounting hole to maintain the positioning state, the subsequent insertion of the connecting head into the mounting hole and the coupling hole can be performed more smoothly. After being fixed to the inner surface of the spine portion of the binder body of the binding, the movement of the binding along a plane parallel to the inner surface of the spine portion of the binding can be reliably prevented.
[0034]
