Description

【０００１】
【発明の属する技術分野】
本発明は、折戸又は引戸等の戸板構造体において、上下ガイドレ−ルにガイドされて走行する支持走行体を保持又は解除することが可能なランナ−ラッチ機構及び該ランナ−ラッチ機構を用いた戸板構造体に関する。
【０００２】
【従来の技術】
従来から、建物の収納スペ−スに用いる折戸は、通常、収納スペ−スの左右両端部を支点として開閉する構造となっており、扉を折り畳みながら開いたり、逆に折り畳んだ扉を平担状にして閉じたりする構造となっている。この時、折戸は収納スペ−スの左右両端部の開閉支点が固定された構造となっていた。それで、開閉支点箇所の近くに収納されている収納物は折戸の戸板１１の蔭になって取り出しにくくなっていた。
【０００３】
そこで、このことを解消するべく、従来の折戸は図５の（イ）及び（ロ）に示すような樹脂製の、くわ型キャッチ部材１４が使用されてきた。該くわ型キャッチ部材１４はガイドレ−ル１２の下面の端部に取り付けられており、戸板１１の上下端部に用いられる吊り車やガイドランナ−などの支持走行体１３の支持シャフト１３ａを、ガイドレ−ル１２の端部の所定位置で、くわ型キャッチ部材１４によって保持又は保持を解除する構造となっている。（特許文献１参照）。
【０００４】
このようにして、折戸の戸板１１を開閉支点から着脱可能にし、開閉支点箇所付近の収納物を取り出し易い構造とされている。また、従来からある引戸においても、戸車やランナ−などの支持走行体１３をガイドレ−ル１２に着脱可能にするために、くわ型キャッチ部材１４が使われてきた。図５の（イ）は、従来の、くわ型キャッチ部材１４の平面図で、（ロ）は、従来の、くわ型キャッチ部材１４を用いたランナ−ラッチ機構の側面図である。

【発明が解決しようとする課題】
しかしながら、上記従来例による、くわ型キャッチ部材１４の場合、折戸や引戸の戸板１１に設けられた吊り車、ランナ−等の支持走行体１３の支持シャフト１３ａがくわ型キャッチ部材１４の溝に嵌合したり逆に溝から抜け出たりを繰り返すと、くわ型キャッチ部材１４の樹脂の摩耗に伴って、その付勢力が低下することによって、支持シャフト１３ａをキャッチし保持する力が低下したり、くわ型キャッチ部材１４をガイドレ−ル１２に固着する時のネジ止め箇所がくわ型キャッチ部材１４の基底部１４ｂの１カ所又はせいぜい２カ所であるので、ガイドレ−ル１２に対して片持ち構造となり、くわ型キャッチ部材１４の基底部１４ｂが塑性変形し、くわ型の２つの係止片１４ａの間隔が広がってキャッチ力が低下し、耐久性に劣るものとなっていた。
【０００７】
また、折戸を取り付け施工するスペ−スの躯体の精度が良くない場合、ややもすれば、左右縦枠１５の垂直度、上枠１６の水平度の精度不良が生じ、折戸の戸板１１の端部と左右縦枠１５との間の平行度が出ず、戸板１１と縦枠１５との間で上部又は下部に隙間が発生することが多いが、従来のくわ型キャッチ部材１４を使用した場合はこの隙間を解消することができなかった。
【０００８】
また、取り付け施工するスペ−スの躯体の精度が良くない場合に、前記戸板１１と縦枠１５の間に生じる隙間の問題は折戸だけでなく、引戸においても発生する問題点である。
【０００９】
本発明の目的は、折戸又は引戸の戸板に設けられた支持走行体を、レ−ル端部に設けたラッチ部材によって保持又は保持を解除する構造の戸板構造体において、左右縦枠の建て付けの精度が不良でも戸板と縦枠間に隙間が発生せず、支持走行体の安定した保持力と長期使用での耐久性を有するランナ−ラッチ機構及び該ランナ−ラッチ機構を用いた戸板構造体を提供することにある。
【００１０】
【課題を解決するための手段】
上記目的を達成するため、本発明の請求項１の発明は、ガイドレ−ル内を、ガイドレ−ルにガイドされて移動する支持走行体と、ガイドレ−ルに取り付けられ、前記支持走行体の支持軸をガイドレ−ルの所定箇所に、保持するラッチプレ−トとからなるランナ−ラッチ機構であって、前記ラッチプレ−トは、一端に開口部を有するくわ型形状の弾性体からなり、該弾性体の長手方向に前記開口部に続くキャッチ溝が設けられており、前記キャッチ溝には前記支持走行体の支持軸を補足する保持部が、前記支持軸の直径よりもやや小さな幅で形成されており、前記ラッチプレ−トがガイドレ−ルに取り付けられ、ガイドレ−ルの所定箇所で、前記支持走行体の支持軸が、前記ラッチプレ−トの保持部に補足されて係止されるようになっており、前記支持走行体に対してガイドレ−ルの所定箇所から移動する方向に所定以上の力が加えられると、前記支持走行体の支持軸が前記ラッチプレ−トの保持部から解除される構成となっていることを特徴とする。
【００１１】
係る構成から、支持走行体の支持軸がラッチプレ−トの開口部から挿入され、キャッチ溝内に入り、該キャッチ溝に設けられた保持部に達する。前記ラッチプレ−トがくわ型形状を有する弾性体であり、しかも前記保持部が前記支持走行体の支持軸の直径よりもやや小さな幅で形成されているので、前記支持走行体の支持軸が前記保持部に働く弾性力で安定して保持される。このようにして支持走行体をガイドレ−ルの所定箇所でラッチプレ−トによって保持し係止させることができる。一方、前記支持走行体に対してガイドレ−ルの所定箇所から移動する方向に所定以上の力が加えられると、前記支持走行体の支持軸が前記ラッチプレ−トの保持部から解除されるのである。
【００１２】
しかも、ラッチプレ−トの開口部に続くキャッチ溝に形成された保持部で前記支持走行体の支持軸を保持する構造であるので、戸板と左右縦枠との間の隙間解消作用が発揮される。すなわち、左右縦枠の建て付けの精度が不良でも、戸板を精度不良のままの縦枠に平行となるように押圧してやれば、支持走行体の支持軸を補足する保持部の位置を上部のラッチプレ−トと下部のラッチプレ−トとで、縦枠が狂っている分だけ違えてやれば、戸板と縦枠が平行となり、戸板と縦枠間の隙間が解消する。すなわち、縦枠の狂いを上下ガイドレ−ルに設けた上下のラッチプレ−トの支持軸保持位置の差によって吸収し、縦枠と戸板の隙間が解消するのである。
【００１３】
さらに、ラッチプレ−トが弾性体からなり、ラッチプレ−トの開口部に続くキャッチ溝でラッチプレ−トの比較的奥の方に形成された保持部で、前記支持走行体の支持軸を保持する構造であり、ラッチプレ−トの端部である開口部付近で保持する構造ではないので、長期の使用に際して、支持軸の保持解除を長期にわたって繰り返しても、ラッチプレ−トの弾性体の持つ付勢力の低下が抑制され、従って、支持走行体の支持軸を保持する力が衰えることがなく耐久性能に優れたものとなる。
【００１４】
本発明の請求項２に記載の発明は、請求項１に記載のランナ−ラッチ機構において、前記ラッチプレ−トの保持部形成部分の長さが、前記支持軸の直径よりも長く形成されており、保持部が波型形状を有する段部であることを特徴とする。
【００１５】
係る構成から、戸板の上部と下部に設けた支持走行体を保持するためのランナ−ラッチ機構のラッチプレ−トの保持部形成部分の長さが、前記支持軸の直径よりも長いので、上記の戸板と縦枠の間の隙間解消作用の発揮にとって、よりいっそう好適である。すなわち、左右縦枠の建て付けの精度が不良でも、戸板を精度不良のままの縦枠に平行となるように押圧してやれば、支持走行体の支持軸を補足する保持部形成部分の位置を上部と下部とで縦枠が狂っている分だけ違えてやれば、戸板と縦枠が平行となり、戸板と縦枠間の隙間が解消することになり、この時、前記保持部形成部分の長さが支持軸の直径よりも長いと大きな隙間に有効に対応できる。
【００１６】
また、前記ラッチプレ−トの保持部が波型形状を有する段部であるので、前記支持軸を波型段部によって、よりいっそう確実に補足可能となり、前記隙間を解消する働きもよりいっそう安定したものとなる。支持軸を嵌合するのにちょうど良い形状の波型段部が形成されている。また、長期間使用した後、キャッチ溝の間隔が広がってキャッチ力が多少低下しても、前記保持部の波型段部によって支持軸を保持する構造なので、支持走行体の支持軸を安定して補足することが可能で保持機能が低下しない。また、支持走行体の支持軸が繰り返し着脱することで、ラッチプレ−トのキャッチ溝が多少摩耗しても、波型段部の働きで支持軸をキャッチする保持力が低下しない。
【００１７】
本発明の請求項３に記載の発明は、請求項１又は２に記載のランナ−ラッチ機構において、前記ラッチプレ−トのキャッチ溝の両側にラッチプレ−トの長手方向に沿ってスリットが形成されていることを特徴とする。
【００１８】
係る構成から、支持走行体の支持軸を保持部で補足した際、前記キャッチ溝の両側にスリットを設けることで、ラッチプレ−トの保持部とスリットの間の部分が撓み易くなって、支持軸を保持する働きと前記隙間解消作用が、よりいっそうスム−ズで安定したものとなる。
【００１９】
本発明の請求項４に記載の発明は、請求項１〜３に記載のランナ−ラッチ機構において、前記ラッチプレ−トが弾性を有する合成樹脂成型体によって一体成形されたものであり、ラッチプレ−トの四隅でガイドレ−ルに取り付け固定されていることを特徴とする。
【００２０】
係る構成から、前記ラッチプレ−トが弾性を有する合成樹脂成型体によって一体成形されたものであるので、支持走行体の支持軸を保持する機能や耐久性にとって優れたものとなり、さらに、ラッチプレ−トの四隅でガイドレ−ルに固定されているので、ガイドレ−ルに対して、いわゆる片持ち構造とならず、ラッチプレ−トが塑性変形することがなく、従って支持軸に対する安定した保持力と耐久性を有するランナ−ラッチ機構となる。
【００２１】
本発明の請求項５に記載の発明は、請求項１〜４のいずれかに記載のランナ−ラッチ機構を用いた戸板構造体において、左右の縦枠と上枠とからなる戸板枠と該戸板枠内を走行移動する戸板からなり、該上枠内に上部ガイドレ−ルを、床材に下部ガイドレ−ルを設け、戸板の上部及び下部に支持走行体が設けられ、該支持走行体が上下ガイドレ−ル内を走行移動する構造の戸板構造体において、前記ラッチプレ−トが上下ガイドレ−ルの所定箇所に取り付けられ、戸板を左右いずれかの縦枠に当接させた際に、前記支持走行体の支持軸が、一端が開口したくわ型弾性体からなる前記ラッチプレ−トの開口部から挿入され、ラッチプレ−トのキャッチ溝を通過して保持部に達し、適度な弾性力で保持されて戸板が係止し、戸板がガイドレ−ルを移動する向きに戸板に所定以上の力を加えると、前記支持走行体の支持軸の保持が解除され、戸板がガイドレ−ルに沿って移動可能となることを特徴とする。
【００２２】
係る構成から、戸板上下の支持走行体をガイドレ−ルの所定の箇所で保持し又は解除することが可能で、しかも左右縦枠の建て付け精度が不良でも、戸板を精度不良のままの縦枠に平行となるように押圧してやれば、支持走行体の支持軸を保持する位置を上部と下部とで縦枠が狂っている分だけ調整することが可能で、戸板と縦枠が平行となり、戸板と縦枠間の隙間が解消する。
【００２３】
また、前記保持部が支持軸の直径よりも長く形成されているので、前記隙間解消作用もより効果的であり、保持部が波型形状を有する段部であるので、前記支持軸を波型段部によって、よりいっそう確実に補足可能となり、前記隙間を解消する働きもよりいっそう安定したものとなる。また、長期間使用した後、キャッチ溝の間隔が広がってキャッチ力が多少低下しても、前記保持部の波型段部によって支持軸を保持する構造なので、支持走行体の支持軸を安定して補足することが可能で保持機能が低下しない。さらに、支持走行体の支持軸が繰り返し着脱することで、ラッチプレ−トの樹脂成型体が多少摩耗しても、波型段部の働きで支持軸をキャッチする保持力の低下が軽減できる。
【００２４】
さらに、キャッチ溝の両側にスリットが設けられているので、よりいっそう安定して支持軸を保持可能である。また、ラッチプレ−トの四隅がガイドレ−ルに対して４点固定されているので、ガイドレ−ルに対して、いわゆる片持ち構造とならず、ラッチプレ−トが塑性変形することがなく、支持軸を保持する力が長期にわたって安定し、従って耐久性に優れたものとなる。
【００２５】

以下、本発明の実施の形態を図面を参照にして説明する。図１は本発明のランナ−ラッチ機構を用いた戸板構造体の側面図、図２は本発明のランナ−ラッチ機構の詳細図で、（イ）は図１のＡ部の拡大詳細図（縦枠は図示せず）、（ロ）はその正面図（縦枠は図示せず）、（ハ）は図１のＢ部の拡大詳細図（縦枠は図示せず）、（ニ）はその正面図（縦枠は図示せず）である。図３（イ）は本発明のラッチプレ−トの平面図、（ロ）はその側面図、（ハ）は本発明のラッチプレ−トを上部ガイドレ−ルに取り付けた状態を示す斜視図、（ニ）は本発明のラッチプレ−トを下部ガイドレ−ルに取り付けた状態を示す斜視図である。図４（イ）は上部支持走行体のラッチプレ−トへの保持状態を示す斜視図で、（ロ）は下部支持走行体のラッチプレ−トへの保持状態を示す斜視図である。本例では、真ん中で２枚の戸板が蝶番によって互いに折り畳み可能なように接続された折戸タイプの戸板で説明する。
【００２６】
本発明のランナ−ラッチ機構を用いた戸板構造体は図１、図２に示すように、左右縦枠５（右縦枠は図示せず）と上枠６からなる戸板枠と該戸板枠内を走行移動する戸板１で構成されている。上枠６には上部ガイドレ−ル２Ａが装着されており、下部の床材には下部ガイドレ−ル２Ｂが装着されている。上部ガイドレ−ル２Ａに上部支持走行体３Ａが走行自在に嵌挿されており、該上部支持走行体３Ａは戸板１の上部で戸板の左右両端部に１個づつ取り付けられている。他方、下部ガイドレ−ル２Ｂに下部支持走行体３Ｂが走行自在に設置されており、前記下部支持走行体３Ｂは戸板１の下部で戸板の左右両端部に１個づつ取り付けられている。
【００２７】
上部ガイドレ−ル２Ａの両端部又は左右いずれか片方の端部の所定箇所には、本発明のラッチプレ−ト４が取り付けられている。該ラッチプレ−トの四隅に、例えば取り付けネジＮ等を利用して、上部ガイドレ−ル２Ａの所定箇所に取り付けられている。取り付け方向は前記ラッチプレ−ト４の開口部Ｋが上部ガイドレ−ル２Ａの長手方向の中央部に向く方向とする。前記上部ガイドレ−ル２Ａは、例えばアルミニウム製の押し出し成型体からなり、断面形状は下面が開口した略コの字状を呈する。前記上部支持走行体３Ａは、例えば合成樹脂成型体からなり、上部ガイドレ−ル２Ａに嵌挿される４つの車輪Ｒと該車輪Ｒを回転可能に支える本体部Ｑと基軸Ｐと本体部及び基軸を連結する支持軸Ｊからなり、該基軸Ｐが前記戸板１の上部に取り付けられている。
【００２８】
下部ガイドレ−ル２Ｂの両端部又は左右いずれか片方の端部には、本発明のラッチプレ−ト４が、該ラッチプレ−トの四隅に、例えば取り付けネジＮ等を利用して下部ガイドレ−ル２Ｂの所定箇所に取り付けられている。取り付け方向は前記ラッチプレ−ト４の開口部Ｋが下部ガイドレ−ル２Ｂの長手方向の中央部に向く方向とする。前記下部ガイドレ−ル２Ｂは、上部ガイドレ−ル２Ａと同様、例えばアルミニウム製の押し出し成型体からなっている。前記下部支持走行体３Ｂは、例えば合成樹脂成型体からなり、下部ガイドレ−ル２Ｂ上に設置されて回転する支持軸Ｊと該支持軸Ｊを回転可能に支える基軸Ｐからなり、該基軸Ｐが前記戸板１の下部に取り付けられている。
【００２９】
上部ガイドレ−ル２Ａ及び下部ガイドレ−ル２Ｂの材質は、アルミニウム製の押し出し成型体がコスト、耐久性等で好適であるが、もちろんこれに限定されるものではない。本例では折戸タイプの戸板を例示するが、引戸タイプの場合も上下ガイドレ−ル及び上下支持走行体が引戸タイプに変わるだけで仕組みは基本的に同様である。
【００３０】
図３（イ）図３（ロ）において、本発明のラッチプレ−ト４は平面視、くわ型形状を呈し、所定長さ、幅、厚みを持つ平板状のプレ−トで、その四隅には取り付け用のネジ穴ｍが設けられている。ラッチプレ−ト４の幅はガイドレ−ル２Ａ又は２Ｂの幅とほぼ同じか又は若干小さめとする。材質は弾性復元力を有する材料からできている。くわ型の一端が支持走行体の支持軸の直径よりもやや広い幅を持つ開口部Ｋとなっており、該開口部Ｋの奥はやや幅が狭まっており、開口部Ｋに続くキャッチ溝Ｇが設けられている。該キャッチ溝Ｇには前記支持軸Ｊの直径よりもやや狭い幅を有する保持部Ｈが形成されており、該保持部Ｈの長さは前記支持軸Ｊの直径よりも長くなるように形成されている。該保持部Ｈの先端部はさらに細くなっておりラッチプレ−トの端部付近に達する。
【００３１】
前記保持部Ｈは平面視、波型形状を有する、複数個の、連続又は不連続の段部Ｄが形成されている。該段部Ｄの形状は略半円形状、略半楕円形状、鋸歯形状等の他、曲線や直線を組み合わせした形状を用いることが可能であり、前記支持軸Ｊを補足する機能があればよい。
【００３２】
前記ラッチプレ−ト４のキャッチ溝Ｇの両側にはラッチプレ−ト４の長手方向に沿って、スリットＳが設けられている。該スリットＳはラッチプレ−ト４の厚み方向を貫通して設けられている。スリットＳを設けることで、支持軸を補足した時にラッチプレ−ト４が撓みやすくなるので、支持軸Ｊを適度な力でよりいっそうスム−ズでしかも安定して保持可能となる。
【００３３】
スリットＳの幅が大きいほど、又保持部ＨとスリットＳとの間隔Ｌが狭くなるほど、支持軸Ｊを補足した時にラッチプレ−ト４が撓み易くなり、支持軸Ｊを保持したり又保持を解除したりする時の作用がよりいっそうスム−ズで安定したものとなる。逆にスリットＳの幅が小さくなるほど、又保持部ＨとスリットＳとの間隔Ｌが広くなるほど、支持軸Ｊを補足した時にラッチプレ−トが撓みにくくなり、支持軸Ｊを保持したり又保持を解除したりする時に大きな力を必要とし、支持軸を保持したり保持を解除したりする時の作用のスム−ズさと安定性が減退する。このように、スリットＳの幅と保持部Ｈとの間隔Ｌを変えることで、支持軸を保持し又、保持を解除する際の力加減が変えられる。スリットＳは必ずしも必要とする要素ではなく、スリットＳが設けられていない場合でも、本発明のラッチプレ−トの持つ前記したようなさまざまな機能は有効に働くのである。しかし、スリットＳが設けられていると、これらの働きがよりいっそうスム−ズで安定したものとなる。
【００３４】
また、本発明のラッチプレ−ト４は弾性を有する合成樹脂成型体によって一体的に形成されていることがより好ましい態様である。例えば、硬質の塩化ビニル樹脂成型体、ポロプロピレン樹脂成型体、ナイロン樹脂成型体、ＡＢＳ樹脂成型体等が好適なものとして挙げることができる。しかし、前記スリットＳの幅を極端に大きくして保持部Ｈとの間隔を極端に小さくすれば、塗装鋼板、亜鉛メッキ鋼板、アルミニウム、等の合成樹脂成型体以外のものも利用可能である。
【００３５】
又、ラッチプレ−ト４の四隅をガイドレ−ルに例えば取り付けネジＮ等で取り付け固定することがより好ましい態様である。従来のくわ型キャッチ部材のようにキャッチ部材の１カ所のみ又は多くてもせいぜい２カ所の固定では、キャッチ部材が片持ち構造となり、支持走行体３Ａ又は３Ｂの支持軸Ｊを保持したり保持を解除したりすることを長期間繰り返すと、従来のくわ型キャッチ部材では、くわ型の係止片が片持ち構造ゆえに、キャッチ力が除々に弱まってくるが、本発明のラッチプレ−ト４は四隅でガイドレ−ルに固定するので、長期使用に際しても安定した保持力を長期間維持可能で、長期耐久性に優れたものとなる。
【００３６】
図３の（ハ）と（ニ）は本発明のラッチプレ−ト４の上下ガイドレ−ル２Ａ、２Ｂへの取り付け状態を示し、ラッチプレ−ト４の開口部Ｋが上下ガイドレ−ル２Ａ、２Ｂの中央側へ向くようにして上部ガイドレ−ル２Ａの下面端部又は下部ガイドレ−ル２Ｂの上面端部に、例えばネジ穴ｍを利用して取り付けネジＮでもって取り付ける。図４（イ）図４（ロ）は上下支持走行体３Ａ、３Ｂの支持軸Ｊが本発明のラッチプレ−ト４の保持部Ｈに補足されているところを示す斜視図である。
【００３７】
次に、従来は、縦枠、上枠等の建て付け精度不良が生じると、戸板１の閉時において、縦枠５と戸板１の端部との間で隙間が、ややもすれば発生しがちであったが、、本発明のラッチプレ−ト４を用いた戸板構造体によれば、その隙間が有効に解消できる仕組みについて図１、図２で説明する。
【００３８】
左右縦枠５の建て付け精度が不良でも、戸板１を精度不良のままの縦枠５に平行となるように押圧してやれば、支持走行体３Ａ又は３Ｂの支持軸Ｊを保持する保持部Ｈの波型段部Ｄの位置を上部と下部とで縦枠５が狂っている分だけ違わせるように調整することが可能で、このように調整することで、戸板１と縦枠５が平行となり、戸板１と縦枠５間の隙間（図示せず）が解消できるのである。前記保持部Ｈが支持軸Ｊの直径よりも長さが長いと前記隙間解消作用にとって、よりいっそう好適である。また、ラッチプレ−ト４の保持部Ｈに波型形状を有する段部Ｄが形成されていることも、前記隙間解消作用にとって、よりいっそう好適である。また、ラッチプレ−トにスリットＳが設けられていることで前記隙間解消作用がよりいっそうスム−ズで安定したものとなる。
【００３９】
【発明の効果】
以上のように、本発明に係るランナ−ラッチ機構及び該ランナ−ラッチ機構を用いた戸板構造体によれば、以下の効果を得ることができる。本発明の第１の発明によって、前記ラッチプレ−トがくわ型形状を有する弾性体であり、前記保持部の幅が前記支持軸の直径よりも若干小さい幅を有しているので、支持軸を弾性力で安定して保持することが可能で戸板の支持走行体をガイドレ−ルの所定箇所で安定した力で係止させることができる。また、前記支持走行体にガイドレ−ルの所定箇所から移動する方向に所定以上の力が加えると、前記支持走行体の支持軸がラッチプレ−トの保持部から解除することができる。また、左右縦枠の建て付けの精度が不良でも、戸板を精度不良のままの縦枠に平行となるように押圧してやれば、支持走行体の支持軸を補足する保持部形成部分の位置を上部と下部とで縦枠が狂っている分だけ違えてやれば、戸板と縦枠が平行となり、戸板と縦枠間の隙間が解消可能となる。
【００４０】
また、本発明の第２の発明によれば、ラッチプレ−トの保持部形成部分の長さが前記支持軸の直径よりも長くなるように形成されているので、大きな隙間でも解消可能で、前記戸板の隙間解消作用にとって、よりいっそう好適である。また、ラッチプレ−トの保持部が波型形状を有する段部であるので、前記支持軸を波型段部によってよりいっそう確実に補足可能となり、前記支持軸を保持又は保持を解除する機能にとってよりいっそう好適であり、前記隙間を解消する働きもよりいっそう安定したものとなる。また、長期間使用し、支持走行体の支持軸が繰り返し着脱することで、ラッチプレ−トのキャッチ溝の間隔が広がったり、キャッチ溝に形成された保持部が摩耗してキャッチ力が多少低下しても、前記波型段部の働きで、支持軸を安定して保持する機能安定し長期間使用しても機能が低下しない。従って長期耐久性能に優れたものとなる。
【００４１】
さらに、本発明の第３の発明によれば、支持走行体の支持軸を保持部で補足した際、前記キャッチ溝の両側にスリットが設けられているので、ラッチプレ−トの保持部とスリットの間の部分が撓み易くなって、支持軸の保持と前記隙間解消作用が、よりいっそうスム−ズで安定したものとなる。
【００４２】
さらに、本発明の第４の発明によれば、前記ラッチプレ−トが弾性を有する合成樹脂成型体によって一体成形されたものであるので、支持走行体の支持軸を保持する機能、耐久性に優れたものとなり、さらに、ラッチプレ−トの四隅でガイドレ−ルに固定されているので、ガイドレ−ルに対して、いわゆる片持ち構造とならず、ラッチプレ−トが塑性変形することがなく、安定したキャッチ力と耐久性を有するランナ−ラッチ機構となる。
【００４３】
さらに本発明の第５の発明によれば、縦枠の建て付け精度不良による戸板の隙間解消、長期間使用時の支持軸の着脱繰り返しによるラッチプレ−トの保持力低下防止、安定した保持力の維持、長期耐久性といったような前記したさまざまな効果を有する戸板構造体が可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a runner-latch mechanism capable of holding or releasing a supporting traveling body guided and guided by an upper and lower guide rail in a door plate structure such as a folding door or a sliding door, and a door plate using the runner-latch mechanism. Related to the structure.
[0002]
[Prior art]
Conventionally, folding doors used for the storage space of a building usually have a structure that opens and closes using the left and right ends of the storage space as fulcrums. It is structured to be closed in a shape. At this time, the folding door had a structure in which opening and closing fulcrums at both left and right ends of the storage space were fixed. Therefore, the stored items stored near the opening / closing fulcrum are difficult to take out due to the door plate 11 of the folding door.

In order to solve this problem, a conventional folding door uses a resin-made hook-shaped catch member 14 as shown in FIGS. The hob-shaped catch member 14 is attached to an end of the lower surface of the guide rail 12, and connects the support shaft 13 a of the support traveling body 13 such as a hanging wheel or a guide runner used at the upper and lower ends of the door plate 11 to the guide rail. At a predetermined position at the end of the barrel 12, the holding or release of the holding is performed by the hook-shaped catch member 14. (See Patent Document 1).
[0004]
In this way, the door plate 11 of the folding door is made detachable from the opening / closing fulcrum, so that the stored material near the opening / closing fulcrum can be easily taken out. Also, in conventional sliding doors, a hook-type catch member 14 has been used in order to make a supporting traveling body 13 such as a door roller or a runner detachable from the guide rail 12. FIG. 5A is a plan view of a conventional hoe-shaped catch member 14, and FIG. 5B is a side view of a conventional runner-latch mechanism using the hoe-shaped catch member 14. As shown in FIG.

[Problems to be solved by the invention]
However, in the case of the hoist type catch member 14 according to the above-described conventional example, the support shaft 13a of the support traveling body 13 such as a hanging wheel or a runner provided on the door plate 11 of the folding door or the sliding door fits into the groove of the hoe type catch member 14. When joining and conversely, slipping out of the groove is repeated, the urging force is reduced due to abrasion of the resin of the hoe-shaped catch member 14, so that the force for catching and holding the support shaft 13a is reduced or the hoe is caught. When the die catch member 14 is fixed to the guide rail 12, the screwing point is one at the base part 14b of the hoe type catch member 14 or at most two places. The base portion 14b of the hoe-shaped catch member 14 is plastically deformed, the interval between the two hook-shaped engaging pieces 14a is widened, the catch force is reduced, and the durability is poor. It is had.
[0007]
Also, if the accuracy of the frame of the space to which the folding door is attached and constructed is not good, the verticality of the left and right vertical frames 15 and the horizontality of the upper frame 16 may be poor, and the end of the door 11 of the folding door and the left and right may be slightly deteriorated. There is often no parallelism between the vertical frame 15 and a gap at the top or bottom between the door plate 11 and the vertical frame 15, but when the conventional hook-type catch member 14 is used, this gap is Could not be eliminated.
[0008]
In addition, when the accuracy of the frame of the space to be installed is not good, the problem of the gap generated between the door plate 11 and the vertical frame 15 is a problem that occurs not only in the folding door but also in the sliding door.
[0009]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a door plate structure having a structure in which a support traveling body provided on a door plate of a folding door or a sliding door is held or released by a latch member provided at a rail end portion. Gap between the door plate and the vertical frame even if the accuracy of the runner is poor, and a runner-latch mechanism having stable holding force of the support traveling body and durability for long-term use, and a door plate structure using the runner-latch mechanism Is to provide.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 of the present invention is directed to a support traveling body which is guided by a guide rail in a guide rail and is attached to the guide rail to support the support traveling body. A runner-latch mechanism comprising a latch plate for holding a shaft at a predetermined position on a guide rail, wherein the latch plate is formed of a reed-shaped elastic body having an opening at one end. A catch groove that follows the opening is provided in the longitudinal direction of the support groove, and a holding portion that supplements the support shaft of the support traveling body is formed in the catch groove with a width slightly smaller than the diameter of the support shaft. The latch plate is attached to a guide rail, and at a predetermined position of the guide rail, a support shaft of the support traveling body is supplemented and locked by a holding portion of the latch plate. Yes, When a predetermined force or more is applied to the support traveling body in a direction moving from a predetermined position of the guide rail, the support shaft of the support traveling body is released from the holding portion of the latch plate. It is characterized by having.
[0011]
With this configuration, the support shaft of the support traveling body is inserted through the opening of the latch plate, enters the catch groove, and reaches the holding portion provided in the catch groove. Since the latch plate is an elastic body having a hod shape and the holding portion is formed to have a width slightly smaller than the diameter of the support shaft of the support traveling body, the support shaft of the support traveling body is formed as described above. It is stably held by the elastic force acting on the holding section. In this way, the support traveling body can be held and locked at the predetermined position of the guide rail by the latch plate. On the other hand, when a force greater than a predetermined value is applied to the support traveling body in a direction moving from a predetermined position of the guide rail, the support shaft of the support traveling body is released from the holding portion of the latch plate. .
[0012]
In addition, since the holding portion formed in the catch groove following the opening of the latch plate holds the support shaft of the support traveling body, the effect of eliminating the gap between the door plate and the left and right vertical frames is exhibited. . That is, even if the accuracy of the left and right vertical frames is poor, if the door plate is pressed so as to be parallel to the vertical frames with the poor accuracy, the position of the holding portion that complements the support shaft of the support traveling body can be changed to the upper latch press. If the vertical plate is misaligned between the lower plate and the lower latch plate by an amount corresponding to the deviation of the vertical frame, the door plate and the vertical frame become parallel, and the gap between the door plate and the vertical frame is eliminated. That is, the deviation of the vertical frame is absorbed by the difference between the support shaft holding positions of the upper and lower latch plates provided on the upper and lower guide rails, and the gap between the vertical frame and the door plate is eliminated.
[0013]
Further, a structure in which the latch plate is made of an elastic body and a holding portion formed relatively deep in the latch plate with a catch groove following the opening of the latch plate to hold the support shaft of the support traveling body. Since the latch plate is not held near the opening, which is the end of the latch plate, the biasing force of the elastic body of the latch plate can be maintained even when the holding of the support shaft is repeated for a long time in long-term use. The lowering is suppressed, so that the force for holding the support shaft of the support traveling body does not decrease and the durability is excellent.
[0014]
According to a second aspect of the present invention, in the runner-latch mechanism according to the first aspect, a length of a holding portion forming portion of the latch plate is formed longer than a diameter of the support shaft. The holding portion is a step having a corrugated shape.
[0015]
With such a configuration, the length of the holding portion forming portion of the latch plate of the runner-latch mechanism for holding the supporting traveling members provided on the upper and lower portions of the door plate is longer than the diameter of the support shaft. It is even more suitable for the effect of eliminating the gap between the door plate and the vertical frame. That is, even if the accuracy of the left and right vertical frames is poor, if the door plate is pressed so as to be parallel to the vertical frame with the poor accuracy, the position of the holding portion forming portion that complements the support shaft of the support traveling body is raised. If the vertical frame is different between the lower part and the lower part, the door plate and the vertical frame will be parallel, and the gap between the door plate and the vertical frame will be eliminated, at this time, the length of the holding part forming part If the length is longer than the diameter of the support shaft, it is possible to effectively cope with a large gap.
[0016]
Further, since the holding portion of the latch plate is a step having a corrugated shape, the support shaft can be more reliably supplemented by the corrugated step, and the function of eliminating the gap is further stabilized. It will be. A corrugated step having a shape that is suitable for fitting the support shaft is formed. Also, even after long use, even if the catch groove is widened and the catching force is slightly reduced, the support shaft is held by the corrugated step of the holding portion, so that the support shaft of the support traveling body can be stabilized. Can be supplemented and the holding function does not decrease. Further, even if the catch groove of the latch plate is slightly worn due to the repeated attachment and detachment of the support shaft of the support traveling body, the holding force for catching the support shaft by the action of the corrugated step does not decrease.
[0017]
According to a third aspect of the present invention, in the runner-latch mechanism according to the first or second aspect, a slit is formed on both sides of a catch groove of the latch plate along a longitudinal direction of the latch plate. It is characterized by having.
[0018]
With such a configuration, when the support shaft of the support traveling body is supplemented by the holding portion, by providing slits on both sides of the catch groove, a portion between the holding portion and the slit of the latch plate is easily bent, and the support shaft is provided. And the above-mentioned gap eliminating action becomes smoother and more stable.
[0019]
According to a fourth aspect of the present invention, in the runner-latch mechanism according to the first to third aspects, the latch plate is integrally formed of a synthetic resin molded body having elasticity. Are fixed to the guide rail at the four corners.
[0020]
With this configuration, since the latch plate is integrally formed of a synthetic resin molded body having elasticity, the latch plate is excellent in the function of holding the support shaft of the support traveling body and has excellent durability. Is fixed to the guide rail at the four corners of the guide rail, so that the guide rail does not have a so-called cantilever structure, and the latch plate does not plastically deform, and therefore has a stable holding force and durability against the support shaft. Is a runner-latch mechanism.
[0021]
According to a fifth aspect of the present invention, there is provided a door plate structure using the runner-latch mechanism according to any one of the first to fourth aspects, wherein the door plate frame includes left and right vertical frames and an upper frame. An upper guide rail is provided in the upper frame, a lower guide rail is provided in the floor material, and a support traveling body is provided in upper and lower portions of the door plate. In a door plate structure having a structure that travels in a guide rail, when the latch plate is attached to a predetermined portion of the upper and lower guide rails and the door plate is brought into contact with one of the left and right vertical frames, the support travel is performed. The support shaft of the body is inserted from the opening of the latch plate, which is formed of a hoe-shaped elastic body having one end opened, passes through the catch groove of the latch plate, reaches the holding portion, and is held by an appropriate elastic force. The door plate locks and the door plate guides the guide rail. When the direction of movement to the door leaf applying a predetermined force or more, the retention of the support shaft of the support running body is released, door panel is guide rail - is characterized by comprising movable along the Le.
[0022]
With such a configuration, the support traveling body above and below the door plate can be held or released at predetermined positions on the guide rail, and even if the accuracy of the left and right vertical frames is poor, the vertical frame remains inaccurate. If it is pressed so as to be parallel to, it is possible to adjust the position where the support shaft of the support traveling body is held by the vertical frame at the upper and lower parts, and the door plate and the vertical frame become parallel, And the gap between the vertical frames is eliminated.
[0023]
Further, since the holding portion is formed longer than the diameter of the support shaft, the clearance eliminating action is more effective. Since the holding portion is a step having a corrugated shape, the support shaft is corrugated. By the step portion, it is possible to supplement more reliably, and the action of eliminating the gap becomes more stable. Also, even after long use, even if the catch groove is widened and the catching force is slightly reduced, the support shaft is held by the corrugated step of the holding portion, so that the support shaft of the support traveling body can be stabilized. Can be supplemented and the holding function does not decrease. Further, since the support shaft of the support traveling body is repeatedly attached and detached, even if the resin molded body of the latch plate is slightly worn, a decrease in the holding force for catching the support shaft by the action of the corrugated step can be reduced.
[0024]
Further, since the slits are provided on both sides of the catch groove, the support shaft can be held more stably. Further, since the four corners of the latch plate are fixed to the guide rail at four points, the guide plate does not have a so-called cantilever structure, and the latch plate is not plastically deformed and the support shaft is not deformed. Is stable over a long period of time, and therefore has excellent durability.

[0026]
As shown in FIGS. 1 and 2, a door plate structure using the runner-latch mechanism of the present invention includes a door plate frame including a left and right vertical frame 5 (a right vertical frame is not shown) and an upper frame 6, and the inside of the door plate frame. The door plate 1 travels and moves. An upper guide rail 2A is mounted on the upper frame 6, and a lower guide rail 2B is mounted on a lower floor material. An upper support traveling body 3A is slidably fitted into the upper guide rail 2A, and the upper supporting traveling body 3A is attached to the upper portion of the door plate 1 at each of the left and right ends of the door plate. On the other hand, a lower support traveling body 3B is mounted on the lower guide rail 2B so as to be able to run freely, and the lower supporting traveling body 3B is attached to a lower portion of the door plate 1 at each of left and right ends of the door plate.
[0027]
The latch plate 4 of the present invention is attached to a predetermined location at both ends or one of the left and right ends of the upper guide rail 2A. At four corners of the latch plate, for example, mounting screws N and the like are used to attach to predetermined positions of the upper guide rail 2A. The mounting direction is such that the opening K of the latch plate 4 is directed to the central portion in the longitudinal direction of the upper guide rail 2A. The upper guide rail 2A is made of, for example, an extruded body made of aluminum and has a substantially U-shaped cross section with an open lower surface. The upper support traveling body 3A is made of, for example, a synthetic resin molded body, and includes four wheels R that are inserted into the upper guide rail 2A, a main body Q that rotatably supports the wheels R, a main shaft P, a main shaft, and a main shaft. The base shaft P is attached to an upper portion of the door plate 1.
[0028]
A latch plate 4 of the present invention is provided at both ends or one of the left and right ends of the lower guide rail 2B at four corners of the latch plate using, for example, mounting screws N or the like. At a predetermined location. The mounting direction is such that the opening K of the latch plate 4 is directed to the longitudinal center of the lower guide rail 2B. The lower guide rail 2B, like the upper guide rail 2A, is made of, for example, an extruded body made of aluminum. The lower support traveling body 3B is made of, for example, a synthetic resin molded body, and includes a support shaft J that is installed on the lower guide rail 2B and rotates, and a base shaft P that rotatably supports the support shaft J. It is attached to the lower part of the door plate 1.
[0029]
As the material of the upper guide rail 2A and the lower guide rail 2B, an extruded body made of aluminum is suitable in terms of cost, durability and the like, but is not limited to this. In this example, a folding door type door plate is exemplified. However, in the case of a sliding door type, the mechanism is basically the same except that the upper and lower guide rails and the upper and lower support traveling bodies are changed to the sliding door type.
[0030]
3 (a) and 3 (b), a latch plate 4 of the present invention is a plate-like plate having a predetermined length, width and thickness in plan view, having a hod shape, and has four corners. A screw hole m for attachment is provided. The width of the latch plate 4 is substantially the same as or slightly smaller than the width of the guide rail 2A or 2B. The material is made of a material having elastic restoring force. One end of the hod shape is an opening K having a width slightly larger than the diameter of the support shaft of the support traveling body, and the depth of the opening K is slightly narrower. Is provided. A holding portion H having a width slightly smaller than the diameter of the support shaft J is formed in the catch groove G, and the length of the holding portion H is formed to be longer than the diameter of the support shaft J. ing. The tip of the holding portion H is further narrowed and reaches near the end of the latch plate.
[0031]
The holding portion H is formed with a plurality of continuous or discontinuous steps D having a corrugated shape in plan view. The shape of the step portion D may be a substantially semicircular shape, a substantially semielliptical shape, a sawtooth shape, or a shape obtained by combining curves and straight lines, and may have a function of supplementing the support shaft J. .
[0032]
On both sides of the catch groove G of the latch plate 4, slits S are provided along the longitudinal direction of the latch plate 4. The slit S is provided through the latch plate 4 in the thickness direction. By providing the slit S, the latch plate 4 is easily bent when the support shaft is supplemented, so that the support shaft J can be held more smoothly and stably with an appropriate force.
[0033]
The larger the width of the slit S and the narrower the distance L between the holding portion H and the slit S, the more easily the latch plate 4 bends when the support shaft J is supplemented, and holds or releases the support shaft J. The effect of the wiping is smoother and more stable. Conversely, the smaller the width of the slit S and the wider the distance L between the holding portion H and the slit S, the more difficult it is for the latch plate to bend when the support shaft J is supplemented, thereby holding or supporting the support shaft J. A large force is required for the release, and the smoothness and stability of the operation for holding and releasing the support shaft are reduced. In this manner, by changing the width L of the slit S and the interval L between the holding portions H, the force applied when the support shaft is held or the holding is released can be changed. The slit S is not a necessary element, and even if the slit S is not provided, the above-described various functions of the latch plate of the present invention work effectively. However, when the slits S are provided, these functions become smoother and more stable.
[0034]
In a more preferred embodiment, the latch plate 4 of the present invention is integrally formed of an elastic synthetic resin molded body. For example, a rigid vinyl chloride resin molded product, a propylene resin molded product, a nylon resin molded product, an ABS resin molded product, and the like can be given as preferable examples. However, if the width of the slit S is extremely large and the interval between the slit S and the holding portion H is extremely small, a material other than a synthetic resin molded body such as a coated steel plate, a galvanized steel plate, and aluminum can be used.
[0035]
In a more preferred embodiment, the four corners of the latch plate 4 are fixed to the guide rail with, for example, mounting screws N or the like. In the case of fixing only one or at most two places of the catch member as in the conventional hook type catch member, the catch member has a cantilever structure, and holds or holds the support shaft J of the support traveling body 3A or 3B. If the release is repeated for a long time, the catch force of the conventional hook-type catch member gradually decreases due to the cantilever structure of the hook-type locking piece, but the latch plate 4 of the present invention has four corners. As a result, the holding force can be maintained for a long period of time even when used for a long period of time, and the long-term durability is excellent.
[0036]
FIGS. 3C and 3D show the latch plate 4 of the present invention mounted on the upper and lower guide rails 2A and 2B, and the opening K of the latch plate 4 is formed on the upper and lower guide rails 2A and 2B. It is attached to the lower surface end of the upper guide rail 2A or the upper surface end of the lower guide rail 2B with the mounting screw N by using, for example, a screw hole m so as to face the center side. FIGS. 4 (a) and 4 (b) are perspective views showing the support shafts J of the upper and lower support traveling bodies 3A and 3B being supplemented by the holding portions H of the latch plate 4 of the present invention.
[0037]
Next, in the related art, if the vertical frame, the upper frame, and the like have a poor mounting accuracy, a gap between the vertical frame 5 and the end of the door plate 1 tends to occur when the door plate 1 is closed. However, according to the door plate structure using the latch plate 4 of the present invention, a mechanism for effectively eliminating the gap will be described with reference to FIGS.
[0038]
Even if the mounting accuracy of the left and right vertical frames 5 is poor, if the door plate 1 is pressed so as to be parallel to the vertical frame 5 with the poor accuracy, the holding portion H for holding the support shaft J of the support traveling body 3A or 3B is formed. It is possible to adjust the position of the corrugated step D so that the vertical frame 5 is different between the upper part and the lower part by the amount that the vertical frame 5 is out of order. With this adjustment, the door plate 1 and the vertical frame 5 become parallel. Thus, a gap (not shown) between the door plate 1 and the vertical frame 5 can be eliminated. If the length of the holding portion H is longer than the diameter of the support shaft J, it is more preferable for the clearance eliminating action. Further, it is even more preferable that the step D having a corrugated shape is formed in the holding portion H of the latch plate 4 in order to eliminate the gap. Further, since the slit S is provided in the latch plate, the clearance eliminating action is further smoothed and stabilized.
[0039]
【The invention's effect】
As described above, according to the runner-latch mechanism of the present invention and the door plate structure using the runner-latch mechanism, the following effects can be obtained. According to the first aspect of the present invention, since the latch plate is an elastic body having a hod shape, and the width of the holding portion has a width slightly smaller than the diameter of the support shaft, It can be stably held by the elastic force, and the supporting traveling body of the door plate can be locked at a predetermined position of the guide rail with a stable force. When a predetermined force or more is applied to the support traveling body in a direction moving from a predetermined position of the guide rail, the support shaft of the support traveling body can be released from the holding portion of the latch plate. In addition, even if the accuracy of the left and right vertical frames is poor, if the door plate is pressed so as to be parallel to the vertical frame with the poor accuracy, the position of the holding portion forming portion that supplements the support shaft of the support traveling body is raised. If the vertical frame is different between the lower part and the lower part, the door plate and the vertical frame become parallel, and the gap between the door plate and the vertical frame can be eliminated.
[0040]
Further, according to the second aspect of the present invention, since the length of the holding portion forming portion of the latch plate is formed to be longer than the diameter of the support shaft, even a large gap can be eliminated. It is even more suitable for the clearance action of the door plate. Further, since the holding portion of the latch plate is a step having a corrugated shape, the support shaft can be more reliably supplemented by the corrugated step, which is more effective for holding or releasing the support shaft. This is more preferable, and the function of eliminating the gap becomes more stable. In addition, since the support shaft of the support traveling body is repeatedly attached and detached after being used for a long period of time, the interval between the catch grooves of the latch plate is widened, and the holding portion formed in the catch groove is worn, so that the catching force is slightly reduced. However, the function of stably holding the support shaft is stable due to the function of the corrugated step portion, and the function does not deteriorate even after long-term use. Therefore, it has excellent long-term durability.
[0041]
Furthermore, according to the third aspect of the present invention, when the support shaft of the support traveling body is supplemented by the holding portion, the slit is provided on both sides of the catch groove, so that the latch plate has the holding portion and the slit. The portion between them becomes easy to bend, and the holding of the support shaft and the clearance eliminating action become smoother and more stable.
[0042]
Further, according to the fourth aspect of the present invention, since the latch plate is integrally formed of a synthetic resin molded body having elasticity, it is excellent in the function of holding the support shaft of the support traveling body and the durability. Further, since the latch plate is fixed to the guide rail at the four corners, the latch rail does not have a so-called cantilever structure, and the latch plate is not plastically deformed and is stable. A runner-latch mechanism having a catching force and durability is obtained.
[0043]
Further, according to the fifth aspect of the present invention, the clearance between the door plates is eliminated due to the poor accuracy of the vertical frame installation, the holding force of the latch plate is prevented from lowering due to the repeated attachment and detachment of the support shaft during long-term use, and the stable holding force is maintained. A door plate structure having various effects as described above such as maintenance and long-term durability can be obtained.
