Description

【０００１】
【発明の属する技術分野】
本発明は蝶番及び蝶番の取付構造に関し、より詳しくは蝶番の構成部材が殆ど外観に現れることがなく、意匠性を大幅に向上させることが可能となるとともに、取り付けの際の位置決めを容易且つ正確に行うことができ、仏壇や高級家具に特に好適に使用することができる蝶番及び蝶番の取付構造に関する。
【０００２】
【従来の技術】
家具や仏壇などの扉を本体に対して開閉可能に取り付けるための部材としては、従来より蝶番が広く使用されている。
従来の一般的な蝶番は、図２９に示すように、２枚の板状部材と、これら板状部材に設けられたナックル内に挿通された軸ピンとから構成されており、ビス等を利用して一方の板状部材を本体に、他方の板状部材を扉に固定することで、本体に対して扉が開閉可能に取り付けられる。
【０００３】
しかしながら、このような従来の蝶番は、扉を開けたときに板状部材が見えてしまうため、安っぽい印象を与えてしまうという問題があった。
そこで、かかる問題を解決するために、本願出願人の一人は実公平６−４０８４１号において、一端に凸部が形成された棒状雌部材と、一端に前記凸部と嵌合し得る凹部が形成された棒状雌部材とからなり、前記雄部材及び雌部材にはそれぞれ少なくとも１個の固定孔が穿設されているヒンジ（蝶番）を提案している。
【０００４】
この開示技術は、従来の蝶番における板状部材が存在せず、棒状部材を直接被取付部材に設けた段部に取り付けるように構成したので、ヒンジが目立たず、上記したような外観上の問題点を解消することが可能となり、この点で優れた技術であったが、ヒンジを段部に固定する際にヒンジが回転したりして正確に位置決めすることが難しく、しかも何度も開閉を繰り返していると隙間が発生して見栄えが悪くなるという問題があった。
また、従来の蝶番の場合と同様に、例えばヒンジで本体に接続された扉を本体に対して回動させたとき、即ち扉を開いたときに、扉が本体にあたって傷が付いてしまうことがあるという問題も有していた。
【０００５】
【発明が解決しようとする課題】
本発明は上記したような従来技術の問題点を全て解決すべくなされたものであって、蝶番の構成部材が殆ど外観に現れることがなく意匠性を大幅に向上させることが可能となるとともに、取り付けの際の位置決めを容易且つ正確に行うことができ、さらに蝶番で接続された部材を回動させた時に相手部材に当たって傷が付くことを確実に防止することができる蝶番及び蝶番の取付構造を提供せんとするものである。

【００１０】
【発明の実施の形態】
以下、本発明に係る蝶番及び蝶番の取付構造の好適な実施形態について、図面を参照しつつ説明する。
図１は本発明に係る蝶番の第一実施形態を示す分解説明図である。
第一実施形態に係る蝶番は、第一棒状部材（１）、第二棒状部材（２）、連結部材（３）の３つの部材から構成されている。
第一棒状部材（１）及び第二棒状部材（２）の相対向する一端部には、それぞれ円柱状の凹部（４）が形成されており、これらの凹部（４）に円柱状の連結部材（３）の一端部及び他端部がそれぞれ嵌合されることで、第一棒状部材（１）及び第二棒状部材（２）がその長さ方向に連結され、軸周りに互いに逆方向に回動可能となる。
【００１１】
図２は第一棒状部材（１）及び第二棒状部材（２）の側面図である。
第一棒状部材（１）及び第二棒状部材（２）には、ビスを挿通するための固定孔（５）が軸直角方向に穿設されている。この固定孔（５）の数は１個以上であればよいが、取り付けの安定性のためには２個以上設けることが好ましい。但し、棒状部材の強度等を考慮すると図示例の如く２個とすることが最も好ましい。
【００１２】
図３は図１のＡ−Ａ線拡大断面図であり、図４は図１のＢ−Ｂ線拡大断面図である。
図示のように、第一棒状部材（１）及び第二棒状部材（２）の横断面は、一部変形された多角形状を呈しており、棒状部材の回動中心（Ｏ）を中心とする仮想円（Ｃ）に内接する多角形状の基本輪郭部（６）と、該基本輪郭部（６）の輪郭線と繋がる輪郭線を有し且つ仮想円（Ｃ）の外側に位置する一点を頂点として基本輪郭部（６）から突出する迫り出し部（７）を有し、該迫り出し部の頂点は直角に形成されている。
そして、これら第一棒状部材（１）及び第二棒状部材（２）を被取付部材（例えば扉と本体）に固定する際には、迫り出し部（７）の向きが左右反対になるようにして被取付部材に固定される。そうしないと、左右がバラバラになって扉と本体を連結できなくなる。基本輪郭部（６）を形成する多角形は、図示例では八角形とされているが、角数はこれに限定されない。通常は５角形から１０角形の間の角数とされるが、１０を超える角数をもつ円に近い多角形とすることも可能である。
【００１３】
また、本発明においては、図５に示すように、第一及び第二棒状部材の横断面を、回動中心（Ｏ）を中心とする仮想円（Ｃ）に一致する円形状の基本輪郭部（６）と、該基本輪郭部（６）の輪郭線と繋がる輪郭線を有し且つ仮想円（Ｃ）の外側に位置する一点を頂点として基本輪郭部（６）から突出する迫り出し部（７）を有し、該迫り出し部の頂点は直角に形成されている。
このように、本発明においては、基本輪郭部（６）が多角形の場合と円形の場合があり、いずれの形状を採用することも可能である。
従って、以下に説明する全ての実施形態において、基本輪郭部が多角形のものが図示されている例については円形としてもよく、逆に基本輪郭部が円形のものが図示されている例については多角形とすることが可能である。
【００１４】
迫り出し部（７）の直角を挟む二辺は等しい長さとされており、迫り出し部（７）の直角の頂点（Ｓ）は、基本輪郭部（６）が多角形の場合、円形の場合ともに、仮想円（Ｃ）から外方に突出するように構成されている。
そして、より好ましくは、図６及び図７に示すように、仮想円（Ｃ）の中心（Ｏ）から迫り出し部（７）の頂点（Ｓ）までの距離が、仮想円（Ｃ）の半径をＲとしたときに√２Ｒとなるようにされ、このとき迫り出し部（７）の直角を挟む二辺の長さはＲとなる。
【００１５】
図８は上記構成からなる蝶番の取り付け方法を示す断面図である。
図示のように、蝶番が取り付けられる扉や本体等の被取付部材（Ｂ）の角部に、直角を有する断面正方形状の切欠部（８）を形成し、この切欠部（８）の直角を構成する二面に迫り出し部（７）の直角を構成する二面をそれぞれ密接させた状態で、固定孔（５）にビス（９）を挿入して螺合することにより、蝶番を被取付部材（Ｂ）に取り付けることができる。
このように、蝶番を構成する第一棒状部材（１）及び第二棒状部材（２）が、直角状に迫り出した迫り出し部（７）を有していることで、棒状部材を扉や本体等の被取付部材に対して容易且つ確実に位置決めして精度良く強固に固定することが可能となり、扉の開閉の繰り返し等によって棒状部材が位置ずれを起こして隙間が生じることも防止できる。
【００１６】
また、迫り出し部（７）の直角を構成する二辺の長さを切欠部（８）の直角を構成する二辺の長さよりも長くすることで、被取付部材（Ｂ）の回動時に相手部材に接触することがなくなってスムーズに扉の開閉等を行うことが可能となり、扉が本体に当たって本体に傷が付くことが防がれる。そして、かかる優れた作用効果は、迫り出し部（７）の直角の頂点（Ｓ）が仮想円（Ｃ）から外方に突出していることで、より容易且つ確実に達成されるようになる。
【００１７】
また、本発明に係る蝶番の取付構造として、図９に示すように、迫り出し部（７）と被取付部材（Ｂ）との接面の隙間に０．１〜１ｍｍ程度の厚みの薄板（１０）を介装することができる。これにより、蝶番によって固定される被取付部材同士の間の隙間調整を容易に行うことができる。尚、図を見やすくするために、薄板（１０）は黒く塗りつぶして示している。
薄板（１０）としては、図１０に示すような、中心線（Ｍ）で折曲可能に形成された長方形状の薄板を使用することが好ましい。薄板（１０）の材質としては、塩化ビニル等を例示することができるが特にこれに限定されるものではない。
このように形成された薄板（１０）は、中心線（Ｍ）で直角に折曲することにより、図９に示すように迫り出し部（７）と被取付部材（Ｂ）との２つの接面の両方の隙間に同時に介装することができ、被取付部材間（例えば、扉と扉の間、扉と本体の間等）の２つの接面における隙間調整を容易に行うことができる。
また、中心線（Ｍ）で折って分離して、分離された一方の板のみを迫り出し部（７）と被取付部材（Ｂ）との接面の一方の隙間に介装することも可能であり、この場合には隙間調整したい方を選択して介装することができる。
【００１８】
尚、図示例では横断面の基本輪郭部（６）が多角形の場合のみを示したが、基本輪郭部（６）が円形の場合であっても全く同様に取り付けることができ、同様の作用効果を奏することができる。
【００１９】
図１１は上記した第一実施形態に係る蝶番の変更例を示す横断面図である。
この変更例における蝶番では、第一棒状部材（１）及び第二棒状部材（２）の横断面の形状が上記したものと異なっているが、他の部分の構成は同じであるため棒状部材のみを図示している。
具体的には、迫り出し部（７）の頂点の直角を構成する二つの辺の基端部（Ｋ）（迫り出し部（７）と基本輪郭部（６）とが繋がる部分）が仮想円（Ｃ）の内側に位置している（図１２参照）とともに、該基端部（Ｋ）と基本輪郭部（６）とを結ぶ線が鋭角（α）を形成し、ちょうど円の一部を略Ｍ形に切り欠いたような形状となっている。但し、この例においても、迫り出し部（７）の直角の頂点（Ｓ）は仮想円（Ｃ）から外方に突出している。鋭角（α）の角度は特に限定されないが、例えば４５度とすることが好ましい。
【００２０】
このような横断面形状を有する棒状部材も、前述例の場合と同様に、被取付部材（Ｂ）の角部に直角の切欠部（８）を形成し、この切欠部（８）の直角を構成する二面に迫り出し部（７）の直角を構成する二面をそれぞれ密接させた状態で、固定孔（５）にビス（９）を挿入して螺合することにより、被取付部材（Ｂ）に取り付けることができる（図１３参照）。
このとき、迫り出し部（７）の頂点の直角を構成する二つの辺の基端部（Ｋ）が仮想円（Ｃ）の内側に位置していることで、図１４及び図１５に示すように、被取付部材間の隙間調整のための薄板（１０）を、迫り出し部（７）と被取付部材（Ｂ）との接面の隙間に確実に密着して介装した取付構造とすることが可能となる。
【００２１】
この場合も、薄板（１０）としては、中心線（Ｍ）で折曲可能に形成された長方形状の薄板が好適に使用されるが、図１６に示すように薄板（１０）の両側部が鋭角（α）に形成されたものが使用される。
このような薄板（１０）を使用すると、基端部（Ｋ）と基本輪郭部（６）とを結ぶ線が鋭角（α）を形成しているため、この鋭角部に薄板（１０）の鋭角部を挿入させることで、被取付部材間（例えば、扉と扉の間、扉と本体の間等）の２つの接面における隙間調整を容易に行うことができるとともに、薄板（１０）をしっかりと密着させて固定することが可能な取付構造となる。
また、この場合も、薄板（１０）を中心線（Ｍ）で折って分離して、分離された一方の板のみを迫り出し部（７）と被取付部材（Ｂ）との接面の一方の隙間に介装することも可能であり、この場合には隙間調整したい方を選択して介装することができる。
【００２２】
図１７及び図１８は上記した第一実施形態に係る蝶番の別の変更例を示す横断面図である。
この変更例における蝶番も、第一棒状部材（１）及び第二棒状部材（２）の横断面の形状が上記したものと異なっているが、他の部分の構成は同じであるため棒状部材のみを図示している。
具体的には、迫り出し部（７）を構成する直角の一辺に凸状固定部（２０）が設けられており、この固定部（２０）を棒状部材（１）（２）が固定される被取付部材（Ｂ）の被固定面に形成された凹部（２１）に嵌合させることで、棒状部材を被取付部材（Ｂ）に固定できるように構成されている。
この固定部（２０）は、直角のいずれの一辺に設けてもよく、いずれの一辺に設けるかによって図１７及び図１８に示すように、被取付部材（Ｂ）の被固定面が変わってくる。
また、固定部（２０）は図示例では１個のみ設けられているが、複数個設けることも可能である。この変更例に係る蝶番によれば、蝶番を被取付部材に対して確実且つ正確にしっかりと位置決め固定することが可能となる。
【００２３】
以上説明した実施形態に係る蝶番において、第一棒状部材（１）及び第二棒状部材（２）との連結構造は図１に示した方法に限定されず、例えば以下のような連結構造を採ることもできる。
図１９乃至図２１はそれぞれ連結構造の変更例を示す断面図である。
尚、これらの図は連結構造を説明するための図であるため、ビスを挿通するための孔等の図示は省略している。
図１９乃至図２１に示す連結構造は、第一棒状部材（１）及び第二棒状部材（２）の一端部にそれぞれ凹部（４）を形成し、これらの凹部（４）に円柱状の連結部材（３）の一端部及び他端部をそれぞれ嵌合した点においては、図１に示した構造と同じであるが、以下の点において異なっている。
【００２４】
図１９示の連結構造においては、第一棒状部材（１）及び第二棒状部材（２）の凹部（４）の底面にそれぞれ半球状の凸状部（１３）が形成されており、これによって、連結部材（３）の端面と凹部（４）の底面との間の摩擦を減少させることができ、蝶番の開閉を円滑に行うことが可能となる。
図２０示の連結構造においては、第一棒状部材（１）の凹部（４）と連結部材（３）の一端部との間、及び第二棒状部材（２）の凹部（４）と連結部材（３）の他端部との間に球状の軸受部材（１４）が介装されており、これによって、連結部材（３）の端面と凹部（４）の底面との間の摩擦を減少させることができ、蝶番の開閉を円滑に行うことが可能となる。
尚、軸受部材（１４）は、図示例の如く両方の凹部に設けることが好ましいが、いずれか一方のみに設けてもよい。
【００２５】
図２１示の連結構造は、連結部材（３）の一端面及び他端面をそれぞれ切り欠いて突起（１５）を形成するとともに、第一棒状部材（１）及び第二棒状部材（２）の凹部（４）の底面に突出部（１６）を形成し、この突出部（１６）が連結部材（３）の切り欠かれた部分に入り込むように構成したものである。
図２２（ａ）はこの連結構造における第一棒状部材（１）及び第二棒状部材（２）を連結部側からみた図であり、（ｂ）は連結部材（３）の一端面及び他端面の平面図であり、（ｃ）（ｄ）は棒状部材の凹部に連結部材を嵌合させたときの突起（１５）と突出部（１６）の位置関係を模式的に示した図である。
【００２６】
図２２（ａ）（ｂ）に示した例では、突起（１５）及び突出部（１６）はいずれも中心角９０度の円弧状に形成されており、これによって（ｃ）（ｄ）に示すように、第一棒状部材に対して第二棒状部材を１８０度回転させたときに突起（１５）と突出部（１６）とが当接してそれ以上の回転が行えないようになる。
尚、この回転可能な角度は、中心角の角度を変更することによって変更することができる。また、突起（１５）及び突出部（１６）の形状は円弧状に限定されず、四角形などの他の形状としてもよい。
【００２７】
このような連結構造によれば、第一棒状部材に対して第二棒状部材の角度が一定範囲に規制されるので、蝶番で接続された扉を本体に対して回動させたときに、扉が本体に当たって傷が付くことが防止できる。
尚、この作用効果は、同様の作用効果を有する図２４示の連結構造の作用効果説明図である図２６を参照することで容易に理解できると思われる。
【００２８】
図２３示の連結構造は、第一棒状部材（１）の一端部に凹部（４）が形成され、第二棒状部材（２）の一端部に該凹部（４）に嵌合可能な凸部（１７）が形成されてなるものであり、この構造によれば、連結部材（３）が不要となるため、部品点数を少なくすることができる。
尚、図示していないが、この連結構造において、凹部（４）に半球状の凸状部（１３）を設けたり、球状の軸受部材（１４）を介装することも可能である。
【００２９】
図２４示の連結構造は、第一棒状部材（１）及び第二棒状部材（２）の対向する一端面をそれぞれ切り欠いて突起（１８）を形成し、第一棒状部材（１）の突起（１８）が第二棒状部材（２）の切り欠かれた部分に、第二棒状部材（２）の突起（１８）が第一棒状部材（１）の切り欠かれた部分に、それぞれ入り込むようにすることで、第一棒状部材（１）に対して第二棒状部材（２）を一定角度回転させたときに突起同士が当接して回転が停止するように構成したものである。
すなわち、この連結構造は、図２１示の連結構造と同様の技術思想に基づくものであり、図２１示の連結構造において連結部材（３）と棒状部材の間で行わせていた作用を、棒状部材同士の間で行わせるようにしたものである。
図２５（ａ）はこの連結構造における第一棒状部材（１）を連結部側からみた図であり、（ｂ）は第二棒状部材（２）を連結部側からみた図であり、（ｃ）（ｄ）は棒状部材同士を円柱状の連結部材（３）を介して連結させたときの突起（１８）同士の位置関係を模式的に示した図である。
尚、これらの図では、第一棒状部材の突起を（１８ａ）で示し、第二棒状部材の突起を（１８ｂ）で示している。
【００３０】
図２５（ａ）（ｂ）に示した例では、突起（１８）は中心角９０度の円弧状に形成されており、これによって（ｃ）（ｄ）に示すように、第一棒状部材に対して第二棒状部材を１８０度回転させたときに突起同士（１８ａ）（１８ｂ）が当接してそれ以上の回転が行えないようになる。
尚、この回転可能な角度は中心角の角度を変更することによって変更することができること、突起（１８）の形状は円弧状に限定されないことは、図２１示の連結構造の場合と同様である。
【００３１】
このような連結構造によれば、第一棒状部材に対して第二棒状部材の角度が一定範囲に規制されるので、図２６に示すように、蝶番で接続された扉（Ｔ）を本体（Ｈ）に対して回動させたときに、扉が本体に当たることがなく、扉や本体に傷が付くことが確実に防止できる。
【００３２】
また、本発明においては、図２７に示す如く３つ以上の棒状部材を長さ方向に連結することも可能である。
この場合、第一棒状部材（１）と第二棒状部材（２）とを交互に、上記したいずれかの連結方法で連結すればよい。
すなわち、本発明においては、少なくとも２本以上の棒状部材を連結する訳であるが、どのような本数とした場合でも、被取付部材（例えば扉と本体）に固定する際には、迫り出し部（７）の向きが左右交互になるようにして被取付部材に固定される。また、一般的に棒状部材の本数は偶数本が好ましい。これは、迫り出し部（７）が固定される被取付部材の切欠部（８）を左右交互とする必要があるからである。
【００３３】
図２８は本発明に係る蝶番の使用状態の一例を示す外観図であり、図示例では、２枚の板状の被取付部材（Ｂ）に本発明に係る蝶番（図１に示したもの）４個を連結して固定した状態が示されている。
このように、本発明に係る蝶番は、例えば図示のように固定孔（５）にビス（９）を挿入して被取付部材（Ｂ）に螺合することにより、被取付部材（Ｂ）に形成された切欠部（８）に対して固定され、このように固定されることで、従来の蝶番に比べて外観上目立たなくなる。
【００３４】

The number of the fixing holes (5) may be one or more, but it is preferable to provide two or more for the stability of attachment. However, considering the strength of the rod-shaped member, etc., it is most preferable to use two as shown in the drawing.
[0012]
  3 is an enlarged sectional view taken along line AA in FIG. 1, and FIG. 4 is an enlarged sectional view taken along line BB in FIG.
  As shown in the figure, the cross-sections of the first rod-shaped member (1) and the second rod-shaped member (2) have a partially deformed polygonal shape and are centered on the rotation center (O) of the rod-shaped member. A polygonal basic outline (6) inscribed in the virtual circle (C), and the basic outline (6)A projecting portion (7) that protrudes from the basic contour portion (6) with a point located outside the virtual circle (C) as a vertex having a contour line connected to the contour line of the virtual circle (C), and the vertex of the projecting portion Are formed at right angles.
  And when these 1st rod-shaped member (1) and 2nd rod-shaped member (2) are fixed to a to-be-attached member (for example, a door and a main body), it is made for the direction of a protrusion part (7) to turn right and left. To be fixed to the mounted member. Otherwise, the left and right sides will fall apart, making it impossible to connect the door and the main body. The polygon forming the basic contour portion (6) is an octagon in the illustrated example, but the number of corners is not limited to this. Usually, the number of polygons is between pentagons and decagons, but polygons close to a circle having more than 10 corners are also possible.
[0013]
  Moreover, in this invention, as shown in FIG. 5, the circular basic outline part which corresponds to the virtual circle (C) centering on the rotation center (O) in the cross section of the 1st and 2nd rod-shaped member. (6) and the basic contour (6)A projecting portion (7) that protrudes from the basic contour portion (6) with a point located outside the virtual circle (C) as a vertex having a contour line connected to the contour line of the virtual circle (C), and the vertex of the projecting portion Are formed at right angles.
  Thus, in the present invention, the basic contour portion (6) may be a polygon or a circle, and any shape can be adopted.
  Accordingly, in all the embodiments described below, an example in which a polygonal basic contour portion is illustrated may be circular, and conversely, an example in which a basic contour portion is circular is illustrated. It can be a polygon.
[0014]

Insert the screw (9) into the fixing hole (5) and screw it in place with the two surfaces that make up the right angle of the protruding portion (7) in close contact with the two surfaces that constitute the hinge. It can be attached to the member (B).
  As described above, the first rod-like member (1) and the second rod-like member (2) constituting the hinge have the projecting portion (7) projecting at a right angle so that the rod-shaped member can be attached to the door or Positioning with respect to a member to be attached such as a main body can be easily and reliably positioned and firmly fixed with high accuracy, and it is also possible to prevent the rod-shaped member from being displaced due to repeated opening and closing of the door and the like, thereby generating a gap.
[0016]
  Further, by making the length of the two sides constituting the right angle of the protruding portion (7) longer than the length of the two sides constituting the right angle of the notch portion (8), the attached member (B) is rotated. It is possible to smoothly open and close the door without contact with the mating member, and the door is prevented from hitting the main body and scratching the main body. And this outstanding effect is achieved more easily and reliably because the perpendicular vertex (S) of the protruding portion (7) projects outward from the virtual circle (C).
[0017]
  In addition, the present inventionAs a hinge mounting structure related toAs shown in FIG. 9, a thin plate (10) having a thickness of about 0.1 to 1 mm is interposed in the gap between the contact surfaces of the protruding portion (7) and the mounted member (B).Can do. ThisThe clearance adjustment between the to-be-attached members fixed with a hinge can be performed easily. In order to make the drawing easier to see, the thin plate (10) is shown in black.

The contact (7) and the member to be mounted (B) are in close contact with the gap between the contact surfaces.Mounting structureIt becomes possible.
[0021]
  Also in this case, as the thin plate (10), a rectangular thin plate that can be bent at the center line (M) is preferably used. However, as shown in FIG. Those formed at an acute angle (α) are used.
  When such a thin plate (10) is used, the line connecting the base end portion (K) and the basic contour portion (6) forms an acute angle (α). Therefore, the acute angle of the thin plate (10) is formed at the acute angle portion. By inserting the portion, it is possible to easily adjust the gap between the two contact surfaces between the attached members (for example, between the doors, between the doors and the main body, etc.) and firmly fix the thin plate (10). Can be fixed in close contact withMounting structureIt becomes.
  Also in this case, the thin plate (10) is folded at the center line (M) and separated, and only one of the separated plates is exposed to one of the contact surfaces of the protruding portion (7) and the mounted member (B). In this case, it is possible to select and insert a person who wants to adjust the gap.
[0022]
  FIG.17 and FIG.18 is a cross-sectional view which shows another example of a change of the hinge concerning 1st embodiment mentioned above.
  The hinge in this modified example is also different in the shape of the cross section of the first rod-shaped member (1) and the second rod-shaped member (2), but the configuration of the other parts is the same, so only the rod-shaped member. Is illustrated.
  Specifically, a convex fixing part (20) is provided on one side of the right angle constituting the protruding part (7), and the rod-like members (1) and (2) are fixed to the fixing part (20). The rod-shaped member can be fixed to the mounted member (B) by being fitted into a recess (21) formed on the fixed surface of the mounted member (B).
  The fixing portion (20) may be provided on any one side of the right angle, and as shown in FIGS. 17 and 18, the surface to be fixed of the attachment member (B) varies depending on which one side is provided. .
