Description

【０００１】
【発明の属する技術分野】
この発明は、綴具に関し、特にたとえば、リングバインダないしファイルとして用いられる綴具に関する。
【０００２】
【従来の技術】
従来、バインダとして、リングバインダがあるが、リングバインダは、略環状の綴杆が中央で噛み合って閉じられるように形成され、例えばリングを手で開閉する場合、略環状の綴杆を構成する一対の略半円形状の綴杆を、両者が離間するように指で引っ張ることにより、綴杆が開くように形成されている。
しかしながら、この略環状の綴杆を指で開くとき、比較的多く書類等の被綴じ物が綴じられているとき、指で綴杆を構成する一対の略半円形状の綴杆を開きにくいことがある。そこで、例えば、特許文献１に開示されたリングファイルが提案されている。さらに、特許文献１に開示されたリングファイルの他に、図１９および図２０に示すようなリングバインダが提案されている。このリングバインダ１では、長手方向に配置された略半円形状の綴杆が連結され、幅方向に配置された略半円形状の綴杆２ａが噛み合わさせることにより、複数の円環状の綴杆２が形成される。そして、綴杆２を開くときには、噛み合わさった一対の略半円形状の綴杆２ａを互いに逆向きに移動させることにより、連結された長手方向の略半円形状の綴杆２ａが長手方向（図１９に示す矢印の方向）に同時に移動する。それにより、ばねなどの弾性力により綴杆２ａが離間するように構成されている。
【０００３】
【特許文献１】
特開平１０−３３７９８８号公報
【０００４】
【発明が解決しようとする課題】
しかしながら、特許文献１のリングファイルの綴具においても、被綴じ物を略環状の綴杆に数多く閉じたとき、操作レバーの内側を側方に押して綴杆を開くように構成されているが、操作レバーを被綴じ物側から外側に向けて押して綴杆を開こうとしたとき、被綴じ物が障害となって、指で操作レバーを押しにくいという問題がある。
また、図１９および図２０に示したリングファイルでは、綴杆に手が当たったりなどすることで衝撃が加わり、不意に綴杆が開放される問題がある。
【０００５】
それゆえに、この発明の主たる目的は、綴具の綴杆の頂部を手で操作することにより、比較的容易に開閉することができ、且つ不意に綴杆が開放されることのない綴具を提供することである。
【０００６】
【課題を解決するための手段】
この発明の請求項１に記載の綴具は、２つの半割杆が組み合わされて略円環状に形成される綴杆と、綴杆を間隔をおいて設けることができる長さを備えた保持部材と、各半割杆がその基部において間隔をおいてその表面に固定され、各半割杆が保持部材に固定されるように保持部材の内側に可動自在に固定された作動部材とを備えた、綴具であって、作動部材は、保持部材内で突き合わされた状態で保持部材の長手方向に移動可能で、綴杆を開く方向に回動可能な一対の作動片からなり、一方の作動片には一方の半割杆の基部が固定され、他方の作動片には他方の半割杆の基部が固定され、作動片は、綴杆が閉じるとき、保持部材の内面より離れた位置において、その突き合わせ縁が突き合わせされた状態において作動片が保持され、綴杆が開くとき、保持部材の内面に近づいた方向に向いて、その突き合わせ縁が保持されるように保持部材に固定され、作動片が保持部材内で保持部材の長手方向に移動しない方向に、かつ作動片の突き合わせ部が保持部材の内面に近づく方向に力を加えるための開閉部材を有し一方の作動片の保持部材の長手方向への移動を抑止することができるロック部材を有する、綴具である。
この発明の請求項２に記載の綴具は、ロック部材は、一方の作動片の保持部材の長手方向の一端に揺動自在に設けられた掛止片であり、掛止片は、他方の作動片の方向に傾倒されることにより、他方の作動片の長手方向の一端に掛止する、請求項１に記載の綴具である。
【０００７】
【作用】
この発明によれば、綴杆と、綴杆を間隔をおいて設けることができる長さを備えた保持部材と、各綴杆がその基部において間隔をおいてその表面に固定され、綴杆が保持部材に固定されるように保持部材の内側に可動自在に固定された作動部材とを備えた、綴具であって、作動部材は、保持部材内で保持部材の長手方向に移動する一対の作動片からなり、一方の作動片には綴杆の一方の基部が固定され、他方の作動片には綴杆の他方の基部が固定され、綴杆が閉じるときには、保持部材の内面より離れた位置において、その突き合わせ縁が突き合わせた状態において保持され、綴杆が開くときには、保持部材の内面に近づいた方向に向いて保持されるように保持部材に固定され、綴杆を開くときに、作動片を保持部材内で保持部材の長手方向に移動させるとともに、保持部材の内面に近づいた方向に保持されるように、綴杆を開く方向に変化させる開閉部材が設けられているので、開閉部材によって綴杆を開閉させる。また、ロック部材である掛止片を左右に傾倒されることで、作動片の長手方向への移動を抑止したり開放することにより、綴具の開放動作を任意に制御することができる。
【０００８】
この発明の上述の目的，その他の目的，特徴および利点は、図面を参照して行う以下の発明の実施の形態の詳細な説明から一層明らかとなろう。
【０００９】
【発明の実施の形態】
図１は、本発明にかかる綴具の一例を示す斜視図である。図２は、閉じた状態における綴具の平面図であり、図３は、閉じた状態における綴具の底面図であり、図４は、閉じた状態における綴具の横断面図である。図５は、開いた状態における綴具の平面図であり、図６は、開いた状態における綴具の底面図であり、図７は、開いた状態における綴具の横断面図である。図８は、閉じた状態における綴杆の係止部近傍を示す斜視図解図であり、図９は、開いた状態における綴杆の係止部近傍を示す斜視図解図である。図１０および図１１は、綴具の構成を示す図解図である。
【００１０】
綴具１０は、厚紙その他の比較的硬質なシート材からなる表紙Ａの略中央に形成される左右一対の折り線の内側の背表紙の内側表面に固定される。固定する方法としては、綴具１０の長手方向の両端に形成された取付孔２０（後に詳述する）にボルトとナットやはとめ等の固着具を挿通させて、背表紙と一体となるように固定する方法がある。
なお、ここでは、固着具として、ボルトとナットを用いて説明するが、これに限ることなく、例えば、ビス、はとめ、リベット等を用いてもよい。
【００１１】
綴具１０は、一対のそれぞれ略円環状の金属製の第１の綴杆１２および第１の綴杆１２と一対の第２の綴杆１４と、前記第１の綴杆１２および第２の綴杆１４をそれぞれ間隔をおいて設けることができる長さを備えた保持部材１６と、その表面に第１の綴杆１２および第２の綴杆１４が間隔をおいて第１の綴杆１２および第２の綴杆１４のそれぞれの基部が固定され、第１の綴杆１２および第２の綴杆１４が前記保持部材１６に固定されるように保持部材１６の内側に可動自在に固定された作動部材１８とを備える。
【００１２】
保持部材１６は、第１の綴杆１２と第２の綴杆１４とを所定の間隔をおいて設けることができる長さを備える平面略長方形で、その両端、すなわち表紙Ａに取り付ける取付孔２０近傍においては、平面略半円弧状に形成されている。保持部材１６は、第１の綴杆１２および第２の綴杆１４を固定する部位より長手方向における外側近傍より内側に向かって、その中央が膨出した断面略半円弧状の被綴じ物載置部２２を備え、且つ、被綴じ物載置部２２の内側には空間を備え、その空間に作動部材１８等を収容するように構成されている。保持部材１６の被綴じ物載置部２２の両端には、その長手方向に略その一端から他端に亘って、作動部材１８を摺動自在に保持する保持壁が設けられている。この実施の形態においては、保持部材１６の長手方向において、第１の綴杆１２および第２の綴杆１４のそれぞれの外側近傍より内部に亘って略全体において垂下されるように、保持壁２４ａおよび保持壁２４ｂが連設されている。さらに、保持壁２４ａおよび保持壁２４ｂの下端縁より内側に向けて、適宜な間隔をおいて、保持用凸部２４ｃおよび保持用凸部２４ｄが突設されており、第１の作動片３０の外側縁３０ｂおよび第２の作動片３２の外側縁３２ｂの近傍を保持するように形成されている。そして、この保持壁２４ａおよび保持壁２４ｂと被綴じ物載置部２２によって囲繞された空間内に、後に詳しく説明する作動部材１８等が収容される。
また、保持部材１６の下端で取付孔２０の近傍の上方には、後述する掛止片６２の一部を露出させるための切り欠き部１６ａが設けられている。切り欠き部１６ａは、掛止片６２を傾倒させる幅を十分に確保できる大きさをもって開口されている。
【００１３】
保持部材１６の被綴じ物載置部２２には、第１の綴杆１２と第２の綴杆１４とを、一定の間隔（日本工業規格等で決められている一定の長さ）をおいて遊貫するための第１の貫通孔２６と第２の貫通孔２８がそれぞれ穿設されている。第１の貫通孔２６と第２の貫通孔２８とは、第１の綴杆１２と第２の綴杆１４を構成する半割杆１２ａおよび半割杆１２ｂと、第２の綴杆１４を構成する半割杆１４ａおよび半割杆１４ｂとに対応して、保持部材１６の幅方向において左右に分かれて一定の間隔をおいて、２つずつ穿設されている。
【００１４】
作動部材１８は、平面略長方形状金属板からなる一対の第１の作動片３０および第２の作動片３２からなる。第１の作動片３０と第２の作動片３２とは、保持部材１６の空間内において各々その長手方向において並置したとき、各々その内側縁を屈曲自在に係合して、すなわち、その突き合わせ縁３０ａおよび突き合わせ縁３２ａを突き合わせ且つ外側縁３０ｂおよび外側縁３２ｂが保持部材１６の保持壁２４ａおよび保持壁２４ｂの両壁内内側面に接合される。そして、第１の作動片３０および第２の作動片３２は、外側から力が加わらないときには、第１の作動片３０と第２の作動片３２とが谷折り、すなわち保持部材１６の被綴じ物載置部２２の内面より離れた方向（突き合わせ縁３０ａおよび突き合わせ縁３２ａが、図１０図示平面Ｐ_ＸＹより下側）に向いて、あるいはまた、山折り、すなわち保持部材１６の被綴じ物載置部２２の内面に近づいた方向（突き合わせ縁３０ａおよび突き合わせ縁３２ａが図１０図示平面Ｐ_ＸＹより上側）に向いて、その谷折りまたは山折りの状態を維持するように、保持部材１６の内側空間部に内設されている。
【００１５】
作動部材１８は、一方の作動片、すなわち第１の作動片３０における保持部材１６の被綴じ物載置部２２の内側面と対向する表面（すなわち上面）には、第１の綴杆１２を構成する半割杆１２ａの基部が固定され、且つ、前記半割杆１２ａとは一定の間隔をおいて、第２の綴杆１４を構成する半割杆１４ａの基部が固定されている。また、他方の作動片、すなわち第２の作動片３２における保持部材１６の被綴じ物載置部２２と対向する表面（すなわち上面）には、第１の綴杆１２を構成する半割杆１２ｂの基部が固定され、且つ、前記半割杆１２ｂと一定の間隔をおいて、第２の綴杆１４を構成する半割杆１４ｂの基部が固定されている。そして、前記第１の綴杆１２および第２の綴杆１４が閉じるときには、図４に示すように、作動部材１８を構成する第１の作動片３０と第２の作動片３２とは、その突き合わせ縁３０ａおよび突き合わせ縁３２ａが保持部材１６の内面（被綴じ物載置部２２の内面）より離れた方向に向いて（すなわち谷折りの状態）、第１の作動片３０の突き合わせ縁３０ａと第２の作動片３２の突き合わせ縁３２ａとが突き合わされた状態において保持されるとともに、前記第１の綴杆１２および第２の綴杆１４を開くときには、図７に示すように、作動部材１８を構成する第１の作動片３０と第２の作動片３２とは、保持部材１６の内面（被綴じ物載置部２２の内面）に近づいた方向に向いて（すなわち谷折り状態）、第２の作動片３２の突き合わせ縁３２ａとが突き合わされた状態に保持されるように保持部材１６内の空間において固定される。
【００１６】
また、作動部材１８を構成する第１の作動片３０と第２の作動片３２とは、保持部材１６の被綴じ物載置部２２の内面に近づいた方向、すなわち山折りの状態においては、第１の作動片３０と第２の作動片３２の長手方向、すなわち第１の作動片３０と第２の作動片３２に固着された半割杆１２ａと半割杆１４ａとを結ぶ線（Ｘ_１（図１０図示））および半割杆１２ｂと半割杆１４ｂとを結ぶ線（Ｘ_２（図１０図示））と平行な方向に、第１の作動片３０と第２の作動片３２とを移動させることができるように摺動自在に内設されている。
【００１７】
第１の作動片３０と第２の作動片３２の下面、すなわち第１の綴杆１２と第２の綴杆１４の基部が固着された上面とは反対側の面に、第１の綴杆１２と第２の綴杆１４とを開閉方向に変化させる開閉部材４０が設けられている。開閉部材４０は、コイルバネ、トーションバネ、板バネ、ゴム、ウレタンゴム等のような弾性部材から選ばれたものをもって構成されており、この実施の形態においては、引張コイルばねが、第１の作動片３０と第２の作動片３２とを、保持部材１６の空間内で保持部材１６の長手方向において、第１の作動片３０と第２の作動片３２とを逆方向に移動させるとともに、保持部材１６を構成する第１の作動片３０の突き合わせ縁３０ａと第２の作動片３２の突き合わせ縁３２ａが保持部材１６の被綴じ物載置部２２の内面に近づいた方向、すなわち山折り状態に保持されるように設けられている。
【００１８】
開閉部材４０は、その一端が一方の作動片、すなわち第１の作動片３０の下側面に形成された係止凸部３０ｃに固定され、開閉部材４０の他端は、他方の作動片、すなわち第２の作動片３２の下面に形成された係止凸部３２ｃに固定されている。開閉部材４０は、第１の作動片３０と第２の作動片３２との突き合わせ縁３０ａおよび突き合わせ縁３２ａが、谷折り状態（図４図示）、すなわち保持部材１６の被綴じ物載置部２２の内面より離れた状態に保持された状態にあるときに、伸展した状態となるように、第１の作動片３０と第２の作動片３２との間において斜めに架け渡され、この状態において、元の状態に戻ろうとする力が働くように構成されている。
開閉部材４０は、第１の作動片３０および第２の作動片３２のそれぞれの長手方向、すなわち第１の作動片３０の半割杆１２ａを固定する部位と半割杆１４ａを固定する部位とを結ぶ線（Ｘ_１（図１０図示））および第２の作動片３２の半割杆１２ｂを固定する部位と半割杆１４ｂを固定する部位とを結ぶ線（Ｘ_２（図１０図示））と斜めに交差する方向に架け渡されている。
【００１９】
そして、作動部材１８を構成する第１の作動片３０と第２の作動片３２とは、第１の綴杆１２と第２の綴杆１４を開き始めたとき、すなわち、第１の綴杆１２と第２の綴杆１４のそれぞれの係止部５０を指で外したとき、開閉部材４０が元の状態に戻ろうとして、すなわち、伸びていた開閉部材４０が縮む方向に作用し、第１の綴杆１２の半割杆１２ａと半割杆１２ｂとが離れる方向（半割杆１２ａはＯ_１方向で、半割杆１２ｂはＯ_２方向（図２および図９図示））および第２の綴杆１４の半割杆１４ａと半割杆１４ｂとが離れる方向（半割杆１４ａはＯ_１方向で、半割杆１４ｂはＯ_２方向（図２および図９図示））に移動するように作用して、第１の作動片３０と第２の作動片３２とをそれぞれ逆方向に移動させるように作用する。すなわち、第１の作動片３０は、係止部５０を外す方向（Ｏ_１方向）に移動し、第２の作動片３２は、係止部５０を外す方向（Ｏ_２方向）に移動する。さらに、開閉部材４０は、半割杆１２ａと半割杆１２ｂとをおよび半割杆１４ａと半割杆１４ｂとを円周方向（図１０Ｙ_１およびＹ_２方向）に引き離すように作用する。作動部材１８を構成する第１の作動片３０と第２の作動片３２は、谷折り状態から徐々に平面状態となり、そして平面状態から山折り状態に変わる。そして、開閉部材４０は、第１の綴杆１２と第２の綴杆１４とを開いた状態にしたとき、第１の作動片３０の突き合わせ縁３０ａと第２の作動片３２の突き合わせ縁３２ａとが山折り状態、すなわち、保持部材１６の被綴じ物載置部２２の内側面に近づいた状態に保持するように作用する。
【００２０】
第１の綴杆１２は、略円環状となるように、半円弧状の半割杆１２ａと半割杆１２ｂとから構成され、第２の綴杆１４は、略円環状となるように、半円弧状の半割杆１４ａと半割杆１４ｂとから構成されている。そして、用紙Ｐに予め穿設された綴じ孔に挿通して、用紙Ｐを綴じることができるように、半割杆１２ａおよび半割杆１２ｂと、半割杆１４ａと半割杆１４ｂの先端、すなわち第１の綴杆１２および第２の綴杆１４の頂部において、係止部５０が形成されている。第１の綴杆１２を構成する半割杆１２ａと半割杆１２ｂは、半割杆１２ａの係止部５０と、半割杆１２ｂの係止部５０とを係止することにより、環状に係合される。また、第２の綴杆１４を構成する半割杆１４ａと半割杆１４ｂとは、半割杆１４ａの係止部５０と半割杆１４ｂの係止部５０とを係止することにより、環状に係合される。
【００２１】
第１の綴杆１２と第２の綴杆１４とは、それぞれの基部が第１の作動片３０と第２の作動片３２に固着された部分（４箇所）を通る軸Ｙ_１，Ｙ_２および軸Ｘ_１，Ｘ_２（図１０図示）を含む平面Ｐ_ＸＹと垂直な平面を構成するように、第１の作動片３０と第２の作動片３２より立設されている。そして、第１の綴杆１２の軸Ｚ_１（図１１図示）が構成する円形面と第２の綴杆１４の軸Ｚ_２（図１１図示）が構成する円形面とは、平行で、且つ、第１の綴杆１２と第２の綴杆１４が第１の作動片３０と第２の作動片３２と固着された部位を通る平面Ｐ_ＸＹと垂直となるように構成されている。
【００２２】
そして、第１の綴杆１２と第２の綴杆１４とは、同一方向に向けて、その係止部５０を指で外すことができるように構成されている。第１の綴杆１２を構成する半割杆１２ａの先端に形成された係止部５０を構成する先端の凸部５２ａとその凸部５２ａに続く凹部５２ｂと、半割杆１２ｂの係止部５０を構成する先端の凸部５４ａとその先端の凸部５４ａに続く凹部５４ｂとは、第１の綴杆１２を閉じたとき係合するように逆方向に向けて突き出しあるいは凹み形成されている。凸部５２ａと凸部５４ａとは、それぞれ先端から内側に向けて傾斜縁を備えており、すべりながら、第１の綴杆１２および第２の綴杆１４を開閉することができるように形成されている。
また、第２の綴杆１４を構成する半割杆１４ａの先端に形成された係止部５０を構成する凸部５６ａとその凸部５６ａに続く凹部５６ｂと、半割杆１４ｂの係止部５０を構成する先端の凸部５８ａとその先端の凸部５８ａに続く凹部５８ｂとは、第２の綴杆１４を閉じたとき係合するように逆方向に向けて突き出しあるいは凹み形成されている。また、半割杆１２ａの係止部５０を構成する凸部５２ａと半割杆１４ａの係止部５０を構成する凸部５６ａとは、同一方向に向けて突き出し設けられている。また、半割杆１２ｂの係止部５０を構成する凹部５４ｂと半割杆１４ｂの係止部５０を構成する凹部５８ｂとは、同一方向に向けて凹み形成されている。
【００２３】
したがって、第１の綴杆１２の係止部５０を、第１の綴杆１２の頂部を指でねじることにより外すことができ、第１の綴杆１２の係止部５０を指で外すと、第１の作動片３０と第２の作動片３２とが、開閉部材４０が元の状態に戻ろうとする力、すなわち縮まろうとする力が働くことにより、第１の作動片３０と第２の作動片３２とが逆方向に移動する。すなわち、第２の綴杆１４を構成する半割杆１４ａの凸部５６ａと半割杆１４ｂの凸部５８ａとを引き離す方向に作用して、第１の綴杆１２の半割杆１２ａの凸部５２ａと半割杆１２ｂの凸部５４ａとを引き離す方向に作用するとともに、第２の綴杆１４を構成する半割杆１４ａの凸部５６ａと半割杆１４ｂの凸部５８ａとを引き離すように作用する。
【００２４】
また、第２の作動片３２には、図１２に示すように、ロック部材である掛止片６２がリベットやねじなどの固定具６４により揺動自在に取付けられている。掛止片６２は、アルミ材などの板材から形成されている。掛止片６２は、略Ｌ字形の基板６２ａと、基板６２ａの一端部に設けられているつまみ部６２ｂから構成されている。つまみ部６２ｂは、基板６２ａ一端部分の板材が略直角に折り曲げられ、保持部材１６側に向かって基板６２ａから突き出して設けられている。つまみ部６２ｂの形状は略矩形で、その上端は、略直線状に形成されている。基板の他端は略半円形に形成され、第１の作動片３０の動きを阻害しないように、固定具６４により第２の作動片３２の下端部近傍の突き合わせ縁３２ａ近傍に揺動自在に取り付けられている。このとき、つまみ部６２ｂは、保持部材１６の下端近傍に設けられた切り欠き部１６ａから保持部材１６の外部に露出するように取り付けられる。図１２に示すように、掛止片６２は、第１の綴杆１２と第２の綴杆１４とが閉じ合わされている状態において、つまみ部６２ｂが第１の作動片３０側に傾倒されることにより、第１の作動片３０の下端に設けられた切り欠き３０ｄに、つまみ部６２ｂの端部が嵌合され掛止される。これにより、掛止片６２のつまみ部６２ｂにより、第１の作動片３０および第２の作動片３２の保持部材１６内での保持部材１６の長手方向への移動が抑止される。なお、移動の抑止を解除する場合には、図１３に示すように、つまみ部６２ｂを第２の作動片３２側に傾倒させることで、切り欠き３０ｄとつまみ部６２ｂの掛止が解除され、容易に第１の作動片３０と第２の作動片３２を保持部材１６の長手方向への移動を行うことができる。
【００２５】
このように、この実施の形態においては、第１の綴杆１２および第２の綴杆１４の頂部を指でねじることにより、第１の綴杆１２の半割杆１２ａおよび半割杆１２ｂの係止部５０と、第２の綴杆１４の半割杆１４ａおよび半割杆１４ｂの係止部５０を外すことができる。
また、第１の綴杆１２の半割杆１２ａと半割杆１２ｂの係止部５０および第２の綴杆１４の半割杆１４ａと半割杆１４ｂの係止部５０を係合させたとき、第１の作動片３０の突き合わせ縁３０ａと第２の作動片３２の突き合わせ縁３２ａとが、谷折り状態になり、第１の作動片３０と第２の作動片３２とが谷折り状態において、開閉部材４０が第１の作動片３０と第２の作動片３２とを突き合わす方向に向けて収縮するように作用するため、第１の綴杆１２の係止部５０の係合状態および第２の綴杆１４の係止部５０の係合状態を維持することができる。
さらに、掛止片６２により第１の作動片３０と第２の作動片３２の保持部材１６内での動きをロックすることで、半割杆に衝撃が加わったりした場合でも、不意に第１の綴杆１２の係止部５０の係合状態および第２の綴杆１４の係止部５０の係合状態が解除されることがない。
【００２６】
綴具１０を表紙Ａに取り付けるには、保持壁２４ａおよび保持壁２４ｂの下端縁を接合して取付孔２０，２０にボルトナットにより取り付ければよい。さらに、図１４に示すように、適宜空間を設けるためのスペーサ６０を介在させて取り付けてもよい。また、前記実施の形態においては、第１の綴杆１２と第２の綴杆１４といったように、２穴タイプの綴具について説明したが、綴杆を増やした多穴タイプ、例えば、３穴、４穴、２０穴、２６穴、３０穴といった多くの綴杆を備えた綴具とすることができる。
【００２７】
次に、本発明にかかる別の実施の形態について、主として図１５および図１６に基づいて説明する。この実施の形態の綴具１１０は、前記実施の形態の綴具１０と略同様の構成であるが、主として、作動部材および開閉部材が異なるので、それらを中心に、以下説明する。
【００２８】
この綴具１１０を構成する第１の作動片１３０の突き合わせ縁１３０ａの略中央付近には、切り欠き部１３０ｃが形成され、且つ、第２の作動片１３２の突き合わせ縁１３２ａの略中央付近にも、切り欠き部１３２ｃが形成されるとともに、前記切り欠き部１３０ｃの一方端には、開閉部材１４０を係止する係止部１３１ｄが突設され、且つ、前記切り欠き部１３２ｃの一方端には、開閉部材１４０を係止する係止部１３２ｄが突設されている。
前記係止部１３１ｄと前記係止部１３２ｄとは、第１の作動片１３０に第１の綴杆１１２が固定された基部を結ぶ線Ｘ_１、または第２の作動片１３２に第２の綴杆１１４が固定された基部を結ぶ線Ｘ_２の延びる方向に離れて形成されている。
【００２９】
そして、開閉部材１４０は、切り欠き部１３０ｃの開口部と切り欠き部１３２ｃの開口部とが向き合って形成される空間内に添装され、その一端は、係止部１３１ｄに係止され、その他端は、係止部１３２ｄに係止される。さらに、開閉部材１４０の一方の先端１４０ａは、係止部１３１ｄから延びて、第２の作動片１３２の裏側に係止されるとともに、開閉部材１４０の他方の先端１４０ｂは、係止部１３２ｄから延びて第１の作動片１３０の裏側に係止される。而して、開閉部材１４０は、第１の作動片１３０と第２の作動片１３２との突き合わせ縁１３０ａおよび突き合わせ縁１３２ａが、谷折り状態、すなわち保持部材１１６の被綴じ物載置部１２２の内面より離れた状態に保持された状態にあるときに、第１の作動片１３０と第２の作動片１３２を幅方向に引き離そうとするように、第１の作動片１３０と第２の作動片１３２との間において斜めに架け渡され、この状態において、伸びようとする力、すなわち弾発力が働くように構成されている。開閉部材１４０は、第１の作動片１３０および第２の作動片１３２のそれぞれの長手方向、すなわち第１の作動片１３０の半割杆１１２ａを固定する部位と半割杆１１４ａを固定する部位とを結ぶ線（Ｘ_１（図１５図示））および第２の作動片１３２の半割杆１１２ｂを固定する部位と半割杆１１４ｂを固定する部位とを結ぶ線（Ｘ_２（図１５図示））と斜めに交差する方向に架け渡されている。さらに、開閉部材１４０が閉じた状態にあるときは、開閉部材１４０の一方の先端１４０ａが第２の作動片１３２に係止され且つ開閉部材１４０の他方の先端１４０ｂが第１の作動片１３０に係止されてねじられた状態になる。
【００３０】
そして、開閉部材１４０の弾性により、作動部材１１８を構成する第１の作動片１３０と第２の作動片１３２とは、第１の綴杆１１２と第２の綴杆１１４を手で開き始めたとき、すなわち、第１の綴杆１１２と第２の綴杆１１４のそれぞれの係止部１５０を外したとき、第１の綴杆１１２の半割杆１１２ａと半割杆１１２ｂとが離れる方向（半割杆１１２ａはＯ_１方向で、半割杆１１２ｂはＯ_２方向（図１６図示））および第２の綴杆１１４の半割杆１１４ａと半割杆１１４ｂとが離れる方向（半割杆１１４ａはＯ_１方向で、半割杆１１４ｂはＯ_２方向（図１６図示））に移動するとともに、ねじられていた開閉部材１４０が元の状態に戻ろうとして、半割杆１１２ａと半割杆１１２ｂとをおよび半割杆１１４ａと半割杆１１４ｂとを円周方向（半割杆１１２ａおよび半割杆１１４ａはＯ_３方向、半割杆１１２ｂおよび半割杆１１４ｂはＯ_４方向）に引き離すように作用する。すなわち、開閉部材１４０の弾性により、第１の作動片１３０は、係止部１５０を外す方向（Ｏ_１方向）に移動し、第２の作動片１３２は、係止部１５０を外す方向（Ｏ_２方向）に移動する。作動部材１１８を構成する第１の作動片１３０と第２の作動片１３２は、谷折り状態から徐々に平面状態となり、そして平面状態から山折り状態に変わる。そして、開閉部材１４０は、第１の綴杆１１２と第２の綴杆１１４とを開いた状態にしたとき、第１の作動片１３０の突き合わせ縁１３０ａと第２の作動片１３２の突き合わせ縁１３２ａとが山折り状態、すなわち、保持部材１１６の被綴じ物載置部１２２の内側面に近づいた状態に保持するように作用する。
また、この実施形態においても、上述の実施形態と同じ状態に第１の作動片１３０および第２の作動片１３２が配置されており、ロック部材である掛止片１６２のつまみ部１６２ｂを、第１の綴杆１１２と第２の綴杆１１４とが閉じ合わされている状態において、つまみ部１６２ｂを第１の作動片１３０側に傾倒することにより、第１の作動片１３０の下端に設けられた切り欠き１３０ｄに、つまみ部１６２ｂの端部が嵌合され掛止される。これにより、掛止片１６２のつまみ部１６２ｂにより、第１の作動片１３０および第２の作動片１３２の保持部材１１６内での保持部材１１６の長手方向への移動が抑止される。なお、移動の抑止を解除する場合には、先程と同様に、つまみ部１６２ｂを第２の作動片１３２側に傾倒させることで、切り欠き１３０ｄとつまみ部１６２ｂの掛止が解除され、容易に第１の作動片１３０と第２の作動片１３２を保持部材１１６の長手方向への移動を行うことができる。
【００３１】
次に、本発明にかかるさらに別の実施の形態について、主として図１７および図１８に基づいて説明する。この実施の形態の綴具２１０は、前記実施の形態の綴具１０と略同様の構成であるが、主として、開閉部材の架け渡し構造が異なるので、それらを中心に、以下説明する。開閉部材２４０は、２本の弾性部材（第１の開閉部材２４２および第２の開閉部材２４４）からなり、開閉部材２４０を構成する一方の第１の開閉部材２４２は、その一端が一方の作動片、すなわち第１の作動片２３０の下側面に形成された係止凸部２３０ｃに固定され、第１の開閉部材２４２の他端は、他方の作動片、すなわち第２の作動片２３２を跨いで保持部材２１６の一方の保持壁２２４ｂの下面に形成された係止凸部２３２ｄに固定されている。また、開閉部材２４０を構成する他方の第２の開閉部材２４４は、その一端が他方の作動片、すなわち第２の作動片２３２の下側面に形成された係止凸部２３２ｃに固定され、第２の開閉部材２４４の他端は、他方の作動片、すなわち第１の作動片２３０を跨いで保持部材２１６の他方の保持壁２２４ａの下面に形成された係止凸部２３０ｄに固定されている。開閉部材２４０は、第１の作動片２３０と第２の作動片２３２との突き合わせ縁２３０ａおよび突き合わせ縁２３２ａが、谷折り状態、すなわち保持部材２１６の被綴じ物載置部２２２の内面より離れた状態に保持された状態にあるときに、伸展した状態となるように、第１の作動片２３０と保持壁２２４ｂおよび第２の作動片２３２と保持壁２２４ａとの間において斜めに架け渡され、この状態において、元の状態に戻ろうとする力が働くように構成されている。
開閉部材２４０は、第１の作動片２３０および第２の作動片２３２のそれぞれの長手方向、すなわち第１の作動片２３０の半割杆２１２ａを固定する部位と半割杆２１４ａを固定する部位とを結ぶ線（Ｘ_１（図１７図示））および第２の作動片２３２の半割杆２１２ｂを固定する部位と半割杆２１４ｂを固定する部位とを結ぶ線（Ｘ_２（図１７図示））と斜めに交差する方向に架け渡されている。
【００３２】
そして、作動部材２１８を構成する第１の作動片２３０と第２の作動片２３２とは、第１の綴杆２１２と第２の綴杆２１４を手で開き始めたとき、すなわち、第１の綴杆２１２と第２の綴杆２１４のそれぞれの係止部２５０を外したとき、第１の綴杆２１２の半割杆２１２ａと半割杆２１２ｂとが離れる方向（半割杆２１２ａはＯ_１方向で、半割杆２１２ｂはＯ_２方向（図１８図示））および第２の綴杆２１４の半割杆２１４ａと半割杆２１４ｂとが離れる方向（半割杆２１４ａはＯ_１方向で、半割杆２１４ｂはＯ_２方向（図１８図示））に移動するとともに、開閉部材２４０が元の状態に戻ろうとして、すなわち、伸びていた開閉部材２４０が縮む方向に作用し、半割杆２１２ａと半割杆２１２ｂとをおよび半割杆２１４ａと半割杆２１４ｂとを引き離すように円周方向（半割杆２１２ａおよび半割杆２１４ａはＯ_３方向、半割杆２１２ｂおよび半割杆２１４ｂはＯ_４方向）に作用する。すなわち、開閉部材２４０の弾性により、第１の作動片２３０は、係止部２５０を外す方向（Ｏ_１方向）に移動し、第２の作動片２３２は、係止部２５０を外す方向（Ｏ_２方向）に移動する。作動部材２１８を構成する第１の作動片２３０と第２の作動片２３２は、谷折り状態から徐々に平面状態となり、そして平面状態から山折り状態に変わる。そして、開閉部材２４０は、第１の綴杆２１２と第２の綴杆２１４とを開いた状態にしたとき、第１の作動片２３０の突き合わせ縁２３０ａと第２の作動片２３２の突き合わせ縁２３２ａとが山折り状態、すなわち、保持部材２１６の被綴じ物載置部２２２の内側面に近づいた状態に保持するように作用する。
また、この実施形態においても、上述の実施形態と同じ状態に第１の作動片２３０および第２の作動片２３２が配置されており、ロック部材である掛止片２６２のつまみ部２６２ｂを、第１の綴杆２１２と第２の綴杆２１４とが閉じ合わされている状態において、つまみ部２６２ｂを第１の作動片２３０側に傾倒することにより、第１の作動片２３０の下端に設けられた切り欠き２３１ｄに、つまみ部２６２ｂの端部が嵌合され掛止される。これにより、掛止片２６２のつまみ部２６２ｂにより、第１の作動片２３０およびと第２の作動片２３２の保持部材２１６内での保持部材２１６の長手方向への移動が抑止される。なお、移動の抑止を解除する場合には、先程と同様に、つまみ部２６２ｂを第２の作動片２３２側に傾倒させることで、切り欠き２３１ｄとつまみ部２６２ｂの掛止が解除され、容易に第１の作動片２３０と第２の作動片２３２を保持部材２１６の長手方向への移動を行うことができる。
【００３３】
なお、上述したきた実施の形態においては、第１の作動片の下端に設けられた切り欠きに、つまみ部の端部が嵌合されて、掛止片を作動片に掛止させたが、これに限定されることなく、切り欠きを設けずに、切り欠き部の縁につまみ部の傾倒を抑止するような突起状の出っ張りを設け、掛止片を作動片に掛止させた状態から掛止を解除するために、つまみ部を傾倒させるときに、この出っ張りを乗り越えさせるようにして、第１の作動片の下端と、つまみ部の上端を掛止させてもよい。
【００３４】

[Prior art]
Conventionally, there is a ring binder as a binder, and the ring binder is formed so that a substantially annular binding rod is engaged and closed at the center. For example, when the ring is opened and closed by hand, a pair of substantially annular binding rods is formed. The binding rod is formed so that the binding rod is opened by pulling the substantially semicircular binding rod with a finger so as to separate them.
However, when the substantially annular binding rod is opened with a finger, when a relatively large number of documents or other objects to be bound are bound, it is difficult for the fingers to open a pair of substantially semicircular binding rods that constitute the binding rod. There is. Therefore, for example, a ring file disclosed in Patent Document 1 has been proposed. Further, in addition to the ring file disclosed in Patent Document 1, a ring binder as shown in FIGS. 19 and 20 has been proposed. In this ring binder 1, a plurality of annular binding rods are connected by connecting substantially semicircular binding rods arranged in the longitudinal direction and engaging substantially semicircular binding rods 2 a arranged in the width direction. 2 are formed. When the binding rod 2 is opened, the engaged pair of substantially semi-circular binding rods 2a are moved in opposite directions to each other so that the connected substantially semi-circular binding rods 2a in the longitudinal direction are connected in the longitudinal direction (FIG. 19 (in the direction of the arrow shown in FIG. 19). Thus, the binding rods 2a are separated from each other by an elastic force of a spring or the like.
