Description

【０００１】
【発明の属する技術分野】
この発明は、特にクロゼットなどの押入れの開口部を開閉するために使用する引戸及び引戸用ガイドに関するものである。
【０００２】
【従来の技術】
クロゼットの開口部は、一般的に折り畳み式の扉によって開閉される。この折り畳み式の扉は例えば図１５に示すように、２枚ずつに折れ曲がる４枚の扉１００が、クロゼットの開口部１の中心から両側に分かれて開く構造となっている。従って、開扉された扉１００は、クロゼットの開口部１から突出する状態となる。
【０００３】
【発明が解決しようとする課題】
ところで部屋のレイアウトの都合から、クロゼットのような押入れの前に、ベッドなどの家具を置きたい場合がある。しかし、クロゼットの開口部１が折り畳み式の扉１００で開閉されると、開扉された扉１００がクロゼットの開口部１から外側に突出するため、扉１００の前に家具を置くことができない。従って、クロゼットのような押入れの扉１００が折り畳み式では、家具の配置に制約が生じるという問題があった。
【０００４】
またクロゼットを引戸によって開閉する構造とすると、前記した扉が突出するといった弊害は無くなるものの、クロゼットを開放した時、少なくとも一枚の戸板がクロゼットの開口を塞ぎ、開口面積が小さくなってしまうという不満がある。そのためクロゼットを引戸によって開閉する構造とする場合には、なるべく一枚の戸板を小さくし、代わってその数を増加させて開口を閉塞する必要が生じる。そのためクロゼットを引戸によって開閉する構造を採用する場合には、３枚程度の戸板部材を有する引戸が利用される。
しかしながら、３枚の戸板を有する引戸は、クロゼットを閉じたつもりでも、不注意によって戸板同士の間に隙間が残っている場合が多く、一般に使いづらい。
【０００５】
そこでこの発明は、クロゼットなどの押入れを、開口部分から扉の一部が突出することなく開閉することができるようにした引戸を提供することを第一の目的とし、さらに戸板同士を関連づけて移動させ、閉め忘れ等を未然に防止することができる引戸の開発をもう一つの課題とする。
【０００６】
【課題を解決するための手段】
上記の課題を解決するための請求項１に記載の引戸は、第１、第２、第３の３枚の戸板部材が、それぞれレールに沿って移動自在に設けられた引戸であって、各戸板部材が互いに重合して開口部を開放する開扉位置と、各戸板部材同士が移動方向にずれて前記開口部を閉塞する閉扉位置とに各戸板部材同士が関連して移動するように、戸板部材同士を関連付ける２つのガイド部材を戸板部材の上部のレールに摺動可能に内蔵し、前記３枚の戸板部材のうちの中央の第２の戸板部材の上部両端に、それぞれ前記２つのガイド部材を取付け、前記３枚の戸板部材のうち両側の第１及び第３の戸板部材が、前記ガイド部材と相対移動可能であり、さらに第１及び第３の戸板部材は、第２の戸板部材に対して所定の位置までずれたとき、いずれかの前記ガイド部材と係合して第２の戸板部材と相対移動不能に固定され、各戸板部材が互いに重合して開口部を開放する際には、各戸板部材の端部が揃 うようにしたことを特徴とする引戸である。
【０００７】
本発明の引戸では、レールにガイド部材が内蔵され、戸板部材は、当該ガイド部材によって誘導され、関連した動作を行う。
【０００８】
また上記した発明を具体化した請求項２に記載の発明は、第１及び第３の戸板部材にはガイド部材と係合する係合部材が設けられ、前記ガイド部材は、第２の戸板部材と係合又は一体化される中間係合部と、その中間係合部の両側部に設けられ端部が開放されていて第１又は第３の戸板部材の係合部材が係脱可能であるガイド溝が設けられている請求項１に記載の引戸である。
【０００９】
本発明の引戸では、中間に位置する第２の戸板部材の両側にガイド部材が取り付けられている。一方第１及び第３の戸板部材は、前記ガイド部材と相対移動が可能であるが、第１及び第３の戸板部材が第２の戸板部材に対して所定の位置までずれたとき、第１及び第３の戸板部材は、第２の戸板部材に取り付けられたガイド部材と係合する。そのため第１及び第３の戸板部材が、第２の戸板部材に対して所定の位置までずれると、ガイド部材によって第１、第３の戸板部材は、中央の第２の戸板部材と関連付けられ、動作が規制される。
【００１０】
本発明の引戸では、第１及び第３の戸板部材にはガイド部材と係合する係合部材が設けられており、当該係合部材を介して第１、第３の戸板部材とガイド部材が係合する。またガイド部材は、両側部にガイド溝が設けられており、当該ガイド溝は、端部が開放されていて第１又は第３の戸板部材の係合部材が係脱可能である。
【００１１】
本発明では、ガイド部材は、中間係合部によって第２の戸板部材の両端に取り付けられる。そして第１又は第３の戸板部材が移動し、第１又は第３の戸板部材が第２の戸板部材に対して所定の位置関係となると、第１又は第３の戸板部材に設けられた係合部材がガイド溝の開放端から溝内に入り、第１及び第３の戸板部材と中間の第２の戸板部材が関連付けられる。
【００１２】
さらに上記した発明を具体化した請求項３に記載の引戸は、中間係合部の両側部に設けられたガイド溝には、それぞれ第１又は第３の戸板部材に設けられた係合部材が係止される係止部を有し、前記係止部の位置は戸板部材の移動方向にずれ、さらに前記各ガイド部材に、第１及び第３の戸板部材の係合部材のうち、閉扉時に縦枠と接する側に設けられた係合部材と、開扉時に係合する当接部とを設けた請求項２に記載の引戸である。
【００１３】
ガイド部材は、係合部材を介して戸板部材を押し又は引くことにより、各戸板部材に関連付けた動作を行わしめるが、特に本発明の引戸では、ガイド溝に設けられた係止部の位置をずらし、各ガイド部材に、第１及び第３の戸板部材の係合部材のうち、閉扉時に縦枠と接する側に設けられた係合部材と、開扉時に係合する当接部を設けた。こうして設けられた当接部は、戸板部材を押し方向に作用するものであり、引戸を重ね合わせる方向に移動する際に第１又は第３の引戸の係止部材が当接する。
【００１４】
さらに上記した発明を具体化した請求項４に記載の引戸は、ガイド部材の中間係合部は溝状であり、第２の戸板部材にはピンが設けられ、当該ピンが前記溝状の中間係合部に挿入され、ガイド部材と第２の戸板部材は戸板部材の移動方向に相対移動が可能である請求項２又は３のいずれかに記載の引戸である。
【００１５】
本発明の引戸では、中間係合部が溝状であり、第２の戸板部材にはピンが設けられている。そしてガイド部材の溝に、第２の戸板部材のピンが挿入されて両者が係合する。本発明の引戸では、ガイド部材と第２の戸板部材とが、戸板部材の移動方向に相対移動が可能であるため、戸板部材を広げた時にガイド部材と戸板部材の位置関係がずれ、押入れ等を閉じた時の戸板部材同士の重なり部分が減少する。
【００１６】
さらに上記した発明を具体化した請求項５に記載の引戸は、ガイド溝の少なくとも一方には、係合部材よりも幅が狭い部位があり、第１又は第３の戸板部材の係合部材が当該ガイド溝と係合したとき、両者の間に摩擦が発生することを特徴とする請求項２〜４のうちのいずれかに記載の引戸である。
【００１７】
本発明の引戸では、少なくとも一つのガイド溝に、係合部材よりも幅が狭い部位があり、当該部位において、係合部材とガイド溝の間で摩擦が発生する。そのため本発明の引戸では、係合部材がガイド溝の中に入って戸板部材同士が所定の位置関係になる時、例えば戸板部材同士を広げて押入れの開口を閉塞する時、係合部材とガイド溝との間で摩擦が発生し、戸板部材にブレーキが掛かる。従って本発明の引戸では、戸板部材を勢いよく操作しても、戸板部材同士が所定の位置関係となる際に、戸板部材に適度のブレーキがかかり、騒音が抑制される。
【００１８】
さらに上記した発明を具体化した請求項６に記載の引戸は、ガイド溝の少なくとも一方は、第１又は第３の戸板部材の係合部材が当該ガイド溝と係合したときに摩擦を発生させ、係合部材が当該ガイド溝の奥側と係合した際に発生する摩擦は、係合部材が当該ガイド溝の開放側と係合した際に発生する摩擦に比べて強い請求項２〜５のうちのいずれかに記載の引戸である。
【００１９】
本発明の引戸では、第１又は第３の戸板部材の係合部材が当該ガイド溝と係合するとき、両者の間で摩擦が発生する。また本発明の引戸では、発生する摩擦は一様ではなく、係合部材がガイド溝の開放側と係合する場合に比べて奥側と係合する場合がより強い。そのため本発明の引戸では、係合部材がガイド溝の中に入って戸板部材同士が所定の位置関係になる時、例えば戸板部材同士を広げて押入れの開口を閉塞する時、係合部材とガイド溝との間で摩擦が発生し、さらに係合部材がガイド溝の奥に行くと当該摩擦はより強くなる。そのため本発明の引戸では、戸板部材にブレーキが掛かる。したがって本発明の引戸では、戸板部材を勢いよく操作しても、戸板部材同士が所定の位置関係となる際に、戸板部材に適度のブレーキがかかり、騒音が抑制される。
【００２０】
さらに上記した発明を具体化した請求項７に記載の引戸は、第２の戸板部材にはピンが設けられ、ガイド部材の中間係合部は溝状であり、第２の戸板部材のピンは前記溝に係合し、ピンが溝の両端側にある時にピンと溝との間で摩擦が発生する請求項２〜６のうちのいずれかに記載の引戸である。
【００２１】
本発明の引戸では、ガイド部材の中間係合部は溝状である。そのため戸板部材を開いた時にガイド部材と戸板部材の位置関係がずれ、戸板部材同士の重なり部分を減少させる。また本発明の引戸では、ピンが溝の両端側にある時にピンと溝との間で摩擦が発生する。そのため戸板部材同士が所定の位置関係になる時、係合部材と溝との間で摩擦が発生し、戸板部材にブレーキが掛かる。従って本発明の引戸では、戸板部材を勢いよく操作しても、戸板部材同士が所定の位置関係となる際に、戸板部材に適度のブレーキがかかり、騒音が抑制される。
【００２２】
さらに上記した発明を具体化した請求項８に記載の引戸は、前記各ガイド部材の両側には、前記レールの側面に形成された被係合部に係止する係合部がそれぞれ突設され、各ガイド部材には、係合部を被係合部に係止する際に、両方の係合部の幅長を小さくするための切欠部が形成されている請求項１〜７のうちのいずれかに記載の引戸である。
【００２３】
本発明の引戸では、各ガイド部材の両側に、前記レールの側面に形成された被係合部に係止する係合部がそれぞれ突設され、各ガイド部材には、係合部を被係止部に係止する際に、両方の係合部の幅長を小さくするための切欠部が形成されている。本発明の引戸では、ガイド部材をレール等に取り付けるとき、切欠部を押し縮めて係合部の幅長を小さくすることができ、レール等への取り付けが容易である。
【００２４】
さらに上記した発明と同様の作用効果を発揮する引戸用ガイドの発明は、レールに装着されて複数の引戸を関連付けて誘導する引戸用ガイドであって、一つの戸板部材と係合又は一体化される中間係合部と、その中間係合部の両側部に設けられ端部が開放されていて他の戸板部材の一部がそれぞれ係脱可能であるガイド溝が設けられ、各ガイド溝はそれぞれ第１又は第３の戸板部材に設けられた係合部材が係止される係止部を有し、さらに前記各ガイド部材に、第１及び第３の戸板部材の係合部材のうち、閉扉時に縦枠と接する側に設けられた係合部材と、開扉時に係合する当接部を設けたことを特徴とする引戸用ガイドである。
【００２５】
【発明の実施の形態】
この発明の実施の形態を、図面を参照しながら説明する。
図１は、本発明の引戸の一実施の形態の分解斜視図である。図２は、図１の引戸の要部を示す断面側面図である。図３は、図１の引戸の要部を示す断面正面図である。図４は、係合部材をレールに取り付ける状態を示す底面図である。図５は、図１の引戸を開扉状態から閉じる状態をそれぞれ示す概略平面図である。図６は、図１の引戸を閉扉状態から開く状態をそれぞれ示す概略平面図である。
【００２６】
図１〜図４は本発明の一実施の形態の引戸を示し、この引戸は、例えばクロゼットのような押入れの開口部１を第１、第２及び第３の戸板部材１０，２０，３０によって開閉するものである。押入れの開口部１は左右の縦枠２ａ，２ｂと上下枠（上枠４ａのみ図示）とから形成されたものである。
【００２７】
押入れの上枠４ａの下面には、図２の様に天壁５ａと両側壁５ｂとからなる長尺状のレール５が、ビス６により取り付けられ、各戸板部材１０，２０，３０はこのレール５に沿ってそれぞれ移動可能である。
【００２８】
各戸板部材１０，２０，３０の上面で且つその移動方向の両側には、図２の様にピン収納穴８が上下方向に形成されている。そして各ピン収納穴８内には、予め組み合わされた収納部材１２とピン７が挿入されている。実施形態の説明上、各戸板部材１０，２０，３０の一方（図１の左側）に配されたピンをピン７ａとし、他方を７ｂとする。
すなわち各ピン収納穴８には、上面が開口する有底筒状の収納部材１２がそれぞれ嵌入されている。各収納部材１２内には、係合部材としての一対のピン７ａ，７ｂがそれぞれ出退自在に突設されている。尚、各ピン７ａ，７ｂは、収納部材１２に収納されたスプリング１３により、上方に突出する方向に付勢されている。
【００２９】
図１に示すように、前記レール５内には、第１、第２及び第３の戸板部材１０，２０，３０を関連して移動させるための左右一対のガイド部材１１ａ，１１ｂがそれぞれ内蔵されている。両方のガイド部材１１ａ，１１ｂは同一形状であり、互いに点対称の状態で配置される。
【００３０】
一方のガイド部材（図１に示す左側の部材）１１ａを例として説明すると、当該ガイド部材１１ａの幅方向中央には、係止穴（中間係合部）１５が形成されている。係止穴１５は丸穴であり、当該係止穴１５には、引戸の内外方向の中間に位置する第２の戸板部材２０の一方のピン７ａが下方から嵌入される。
またガイド部材１１ａには、押入れ内側の第３の戸板部材３０のピン７ａが係止すべく、一端側で且つ内側の角部を切り欠いてなる当接部９が形成されている。
またガイド部材１１ａの下面であって係止穴１５の側部には、この当接部９に対して戸板部材の移動方向の直線上（以下、直線上という）に沿って長溝状のガイド溝１６ａが形成されている。このガイド溝１６ａの端部は、前記当接部９の近傍に位置し、他端は前記第３の戸板部材３０の他方のピン７ｂの上端が挿脱できるように開口し、開放されている。
尚、ガイド溝１６ａの奥部（端部）は、閉塞しており、当該最奥部は係止部１６ｃとして機能する。
【００３１】
更に、このガイド部材１１ａには、前記係止穴１５よりも外側に前記ガイド溝１６ａと平行な長溝状のガイド溝１６ｂが形成されている。ガイド溝１６ｂは、その一端が前記係止穴１５と並設され、且つ、他端は前側の第１戸板部材１０の一方のピン７ａの上端が挿脱できるように開口し、開放されている。
ガイド溝１６ｂの一端、すなわち最奥部は閉塞しており、当該最奥部は係止部１６ｄとして機能する。
ガイド溝１６ａ，１６ｂを比較すると、前者のガイド溝１６ａは、角部が切り欠かれて当接部９が形成されているので、後者のガイド溝１６ｂに比べて長さが短い。また係止部１６ｃ，１６ｄは、戸板部材１０，２０，３０の移動方向にずれている。そして各係止部１６ｃ，１６ｄと当接部９の関係は、二つのガイド溝１６ａ，１６ｂの内、開放側寄りにある方の係止部１６ｃの縦枠２ａ側に当接部９が設けられたものとなっている。
【００３２】
ガイド部材１１ａの他端側で且つ両方のガイド溝１６ａ，１６ｂの直線上には、ガイド部材１１ａのガイド溝１６ａ，１６ｂの上面から前記レール５の天壁５ａの下面に向けて傾斜する案内面１８を有する案内部１９がそれぞれ突設されている。
【００３３】
またガイド部材１１ａの両側には、係合部２３がそれぞれ突設され、この係合部２３は前記レール５の両側壁５ｂの内面に突設された被係合部としての凸条２２に係止される。そしてこの係合部２３によりガイド部材１１ａは落下することなく、レール５に沿って移動自在に係合する。また、ガイド部材１１ａには、図４に示す如く両方の係合部２３の幅を狭くできるように、他端側からレール５に沿う方向に切欠２４が形成されている。従って、ガイド部材１１ａの両側をガイド部材１１ａの弾性力に抗して内側に押圧することにより、両方の係止部２３の幅をレール５の凸条２２の間隔よりも狭くでき、ガイド部材１１ａを容易にレール５に取り付けることが可能となる。
【００３４】
前記一方のガイド部材１１ａ及びこれと同一形状の他方のガイド部材１１ｂは、その係止穴１５に第２の戸板部材２０のピン７ａ，７ｂが係止されており、両方のガイド部材１１ａ，１１ｂは、第２の戸板部材２０に対して相対的に移動することはない。
【００３５】
本実施の形態の引戸は以上のように構成し、次にその動作について説明する。
先ず、図５（イ）に示すように第１、第２及び第３の戸板部材１０，２０，３０が押入れの開口部１の左の縦枠２ａに寄せ集められ、互いに重合して開口部１を開放する開扉位置にある。このとき、第１の戸板部材１０の一方のピン７ａは、一方のガイド部材１１ａのガイド溝１６ｂの終端の係止部１６ｄに位置し、他方のピン７ｂは、他方のガイド部材１１ｂの当接部９に位置する。
【００３６】
また、第３の戸板部材３０の一方のピン７ａは、一方のガイド部材１１ａの当接部９に位置し、他方のピン７ｂは、他方のガイド部材１１ｂのガイド溝１６ｂの終端の係止部１６ｄに位置する。
【００３７】
そして、押入れの開口部１を閉扉する際には、外側にある第１の戸板部材１０を右側へ移動させる。第１の戸板部材１０が移動する際に、第１の戸板部材１０の一方のピン７ａは、一方のガイド部材１１ａのガイド溝１６ｂ内を摺動し、且つ、他方のピン７ｂは当接部９から離間するため、第１の戸板部材１０のみが移動し、他の第２及び第３の戸板部材１０，２０は停止した状態にある。
【００３８】
一方のピン７ａは第１の戸板部材１０の移動に伴ってガイド溝１６ｂから案内部１９の案内面１８に到達するが、スプリング１３はこのピン７ａを突出する方向に付勢するため、ピン７ａは、案内部１９の案内面１８上を摺動しながら次第に突出し、ほとんど衝撃を与えることなくレール５の天壁５ａの下面に当接する（図３参照）。
【００３９】
更に、第１の戸板部材１０が移動すると、一方のピン７ａは他方のガイド部材１１ｂに達するが、他方のガイド部材１１ｂにも、前記一方のガイド部材１１ｂと同様に案内部１９が設けられていることから、一方のピン７ａは他方のガイド部材１１ｂに案内部１９を介してスムースに乗り移ることができる。この案内部１９の案内面１８を摺動するピン７ａはスプリング１３の弾性力に抗して次第に下方に後退し、他方のガイド部材１１ｂのガイド溝１６ａに入り、ガイド溝１６ａの終端の係止部１６ｃに到達し係合する（図５ロ参照）。
【００４０】
更に、第１の戸板部材１０を移動させると、他方のガイド部材１１ｂのガイド溝１６ａに係合する一方のピン７ａが、この他方のガイド部材１１ｂを移動させる。このガイド部材１１ｂは第２の戸板部材２０に対して相対的に移動不可能であるため、第２の戸板部材２０が第１の戸板部材１０に引っ張られて移動する。
【００４１】
第２の戸板部材２０の移動の初期において、他方のガイド部材１１ｂのガイド溝１６ｂが第３の戸板部材３０の他方のピン７ｂに対して移動し、且つ、一方のピン７ａは一方のガイド部材１１ａの当接部９から離脱するため、両方のガイド部材１１ａ，１１ｂは第２の戸板部材２０と一体的に移動するが、第３の戸板部材３０は停止した状態にある。
【００４２】
他方のガイド部材１１ｂのガイド溝１６ｂから第３の戸板部材３０の他方のピン７ｂが離脱するが（図５ハ参照）、上記したように案内部１９により、このピン７ｂは衝撃なく且つスムースにレール５側に移動する。更に、この他方のピン７ｂが一方のガイド部材１１ａの案内部１９を介してガイド溝１６ａに入る。
【００４３】
従って、第１の戸板部材１０の端部が右の縦枠２ｂに当接すると共に、各戸板部材１０，２０，３０同士が互いにずれることにより、前記開口部１を閉塞する閉扉位置となり、押入れの開口部１は完全に閉塞される（図５ニ参照）。
【００４４】
次に、閉扉された押入れの開口部１を開扉する場合について説明する。図６（イ）の状態にある第１の戸板部材１０を左の方へ移動させると、第１の戸板部材１０の一方のピン７ａは、他方のガイド部材１１ｂのガイド溝１６ａを摺動するため、第１の戸板部材１０のみが移動する。
【００４５】
この一方のピン７ａは案内部１９を介して他方のガイド部材１１ｂからレール５に沿って移動した後に、一方のガイド部材１１ａのガイド溝１６ｂを摺動し、その終端の係止部１６ｄに係止する。また、第１の戸板部材１０の他方のピン７ｂは、他方のガイド部材１１ｂの当接部９に係止する。このとき、第１の戸板部材１０と第２の戸板部材２０とは、互いに重合した状態となる（図６ロ参照）。
【００４６】
この状態で更に第１の戸板部材１０を左に移動させると、両方のガイド部材１１ａ，１１ｂを介して第２の戸板部材２０も同時に移動する。すなわち本実施形態では、第２の戸板部材２０は、その両端の設けられたガイド部材１１ａ，１１ｂの係止部１６ｄと当接部９が戸板部材１０のピン７ａ，７ｂと係合し、戸板部材２０はその両端部において戸板部材１０と係合する。そのため第１の戸板部材１０を左に移動させると、戸板部材２０もバランスよく移動する。
第３の戸板部材３０の他方のピン７ｂは、一方のガイド部材１１ａのガイド溝１６ａから離脱した後に（図６ハ参照）、他方のガイド部材１１ｂのガイド溝１６ｂに入る。
従って、各戸板部材１０，２０，３０はそれぞれ重合した状態でそれぞれの端部が左の縦枠２ａに当接した開扉位置となり、押入れの開口部１は完全に開扉される。
【００４７】
尚、引戸の開閉は、第１の戸板部材１０を左右に移動させることにより行なったが、第３の戸板部材３０を左右に移動させることにより、同様に行なうことも可能である。
即ち、各戸板部材１０，２０，３０は開扉位置状態で前記とは反対の右側の縦枠２ｂ側に位置する。そして、第３の戸板部材３０を左側に移動させると、先ずこの第３の戸板部材３０のみが移動した後に、第３の戸板部材３０の他方のピン７ｂが一方のガイド部材１１ａと係合するため、第２の戸板部材２０も同時移動させることとなり、各戸板部材１０，２０，３０は閉扉位置となる。
【００４８】
また、反対に、閉扉された押入れの開口部１を開扉する際には、第３の戸板部材３０を右に移動させると、この第３の戸板部材３０のみが第２の戸板部材２０に重合するまで移動し、更に、第３の戸板部材３０の他方のピン７ｂが、他方のガイド部材１１ｂと係合するため、第２の戸板部材２０は第３の戸板部材３０と共に移動し、各戸板部材１０，２０，３０がそれぞれ重合する開扉位置となる。
【００４９】
更に、開口部１を閉扉する際には、第１の戸板部材１０を移動させて開口部１の閉扉を行ない、開口部１を閉扉する際には、第３の戸板部材３０を移動させて開扉を行なうことも可能である。
【００５０】
尚、本発明は上記の実施の形態に限定するものではない。例えば、前記両方のガイド部材１１ａ，１１ｂの当接部９は、必ずしも第１及び第３の戸板部材１０，３０のピン７ａ，７ｂが係合する必要はなく、各ピン７ａ，７ｂを逃がすための逃がし用の切欠であっても良い。かかる場合には、第１，第２及び第３の戸板部材１０，２０，３０を同一構造とすることができる利点がある。
【００５１】
また上記した実施形態では、ガイド部材１１ａ，１１ｂの中間部に丸穴状の係止穴１５を設け、戸板部材２０のピン７ａ，７ｂを係合させてガイド部材１１ａ，１１ｂと、第２戸板部材２０とを実質的に一体化した構成を示した。この構成は、戸板部材の動作が円滑である効果があるが、本発明は、この構成にこだわるものではなく、第２戸板部材とガイド部材間の相対移動を許すものであってもよい。
【００５２】
図７は、本発明の他の実施形態で採用するガイド部材の斜視図である。図８は、図７の実施形態において引戸を開扉状態から閉じる状態をそれぞれ示す概略平面図である。
図７に示すガイド部材５０は、先の実施形態と略同一の構成をもつものであるが、先の実施形態のガイド部材１１では、係止穴１５が丸穴であったのに対し、本実施形態のガイド部材５０では、溝状の係止穴５１が形成されている。また係止穴５１は、図７（ａ）（ｃ）に示すように、一端側（ガイド部材５０の中心寄りの端部）が他の部位よりも深く、当該部位は、深穴部５３となっている。
【００５３】
さらにガイド部材５０は、案内部５５の切れ込みが先の実施例よりも長い点と、ガイド溝１６ａの終端に深穴部５６が設けられている点でも相違する。係止穴５１及びガイド溝１６ａの終端に深穴部５３，５６が設けられている理由は、当該深穴部５３，５６にピン７ａ，７ｂが入ることにより、節度感を生じさせ、使用感の向上を図るためである。本実施形態では、ガイド溝１６ａの終端の深穴部５６が係止部として機能する。
【００５４】
さらに、ガイド部材５０は、レール５の凸条２２に係止される係合部５７が二箇所に設けられている点でも先の例と相違するが、係合部５７の機能は、先の例のそれと同一である。
図７（ａ）において、５８で示した窪みは、成形上の要求から生じるものであり、機能上の意味は無い。
【００５５】
図７に示したガイド部材５０を使用すると、閉扉位置に戸板部材を配した場合に、戸板部材同士の重なりが少ないという、特有の効果がある。
【００５６】
即ち、図７に示したガイド部材５０を使用した場合の各部材の開扉位置における位置関係は、図８（イ）の通りであり、第１の戸板部材１０の一方のピン７ａは、一方のガイド部材５０ａのガイド溝１６ｂの終端に位置し、他方のピン７ｂは、他方のガイド部材５０ｂの当接部９に位置し、第３の戸板部材３０の一方のピン７ａは一方のガイド部材５０ａの当接部９に位置し、他方のピン７ｂは、他方のガイド部材５０ｂのガイド溝１６ｂの終端に位置する。
また中間部にある第２戸板部材２０のピン７ａ，７ｂと、ガイド部材５０ａ，５０ｂとの関係は、図８（イ）の通りであり、ピン７ａ，７ｂが溝状の係止穴（中間係合部）５１ａ，５１ｂの外側端部に位置している。
【００５７】
そして、閉扉すべく外側にある第１の戸板部材１０を右側へ移動させると、先の例と同様に、第１の戸板部材１０のみが移動し、先の例と同様に一方のピン７ａは他方のガイド部材５０ｂに達し、遂にはピン７ａは他方のガイド部材５０ｂのガイド溝１６ａに入ってガイド溝１６ａの終端部たる係止部１６ｃに至る（図８ロ）。
【００５８】
ここで、本実施形態では、中間の戸板部材２０に設けられた係止穴５１ａ，５１ｂが溝状であって長さを持つため、さらに第１の戸板部材１０を閉扉方向に移動させると、第２の戸板部材２０のピン７ｂが係止穴５１ｂに沿って相対移動し、第２の戸板部材２０を残してガイド部材５０ｂだけが第２の戸板部材２０に対して進行方向に移動する。
更に、第１の戸板部材１０を移動させると、図８（ハ）の様にガイド部材５０ｂの係止穴５１ｂの内側端部がピン７ｂと当接し、ピン７ｂは深穴部５３と係合する。
【００５９】
そして更に第１の戸板部材１０を移動させると、第２の戸板部材２０は、ガイド部材５０ｂの係止穴５１ｂの内側端部と接しているため、第２の戸板部材２０がガイド部材５０ｂを介して引っ張られる。そのため第２の戸板部材２０は、第１の戸板部材１０に引っ張られて移動する。
【００６０】
この時、図面左側の左枠２ａ側においては、図８（ニ）の様に第２の戸板部材２０だけ移動し、ピン７ａが係止穴５１ａに沿って相対移動する。即ち、ガイド部材５０ａは停止したままの状態で、第２の戸板部材２０だけが係止穴５１ａの長さ分だけ移動する。そしてピン７ａが長穴状の係止穴５１ａの内側端部と接し、ピン７ａは深穴部５３と係合する。
【００６１】
更に第１の戸板部材１０を移動させると、第２の戸板部材２０は第１の戸板部材１０と一体的に移動する。
そして遂には第１の戸板部材１０の端部が右の縦枠２ｂに当接すると共に、各戸板部材１０，２０，３０同士が互いにずれ広がることにより、前記開口部１を閉塞する閉扉位置となり、押入れの開口部１は完全に閉塞される（図８ホ参照）。
【００６２】
そして閉扉状態においては、中間部にある第２戸板部材２０のピン７ａ，７ｂと、ガイド部材５０ａ，５０ｂとの関係は、先の実施形態の開扉位置における場合に比べて、ガイド部材５０ａ，５０ｂが第２戸板部材２０の幅方向に離れたものとなる。その結果、第１戸板部材１０と第２戸板部材２０の重なり、および第２戸板部材２０と第３戸板部材３０の重なりは、先の例に比べて小さなものとなる。
尚この作用は、先に説明した例では、閉扉位置において、隣あう戸板部材１０，２０，３０のピン７ａ，７ｂが、図５（ニ）の様に交差した位置関係であるのに対し、本実施形態では、図８（ハ）の様に直線上に並ぶことからも理解できる。
【００６３】
次に、もう一つの実施形態について説明する。
図９は、本発明の他の実施の形態で採用するガイド部材の斜視図である。図１０は、図９のガイド部材の正面図及び平面図である。図１１は、図９のガイド部材のガイド溝の溝幅を示す説明図である。図１２は、レールとガイド及び戸板部材の関係を示す断面図である。図１３の（イ）〜（ホ）は引戸を開扉状態から閉じる状態をそれぞれ示す概略平面図である。図１４の（イ）〜（ホ）は引戸を閉扉状態から開く状態をそれぞれ示す概略平面図である。
【００６４】
前述した実施形態では、ガイド溝１６ａ，１６ｂは、いずれも天面が塞がったものであったのに対し、本実施形態のガイド部材７０は、天面が開放されている点で相違する。
すなわちガイド部材７０は、左右に二列のガイド溝１６ａ，１６ｂを持ち、これらのガイド溝１６ａ，１６ｂは、先の実施形態と同様に一端側が開放されている。ガイド溝１６ａ，１６ｂは、いずれも板状のベース７１から立設された壁７２によって構成され、いずれの部位も天面が開放されている。
またガイド溝１６ａ，１６ｂは先の実施形態と同様に一方のガイド溝１６ａが短く、他方が長いが、短い方のガイド溝１６ａの列の背面側に、もう一つのガイド溝１６ｅが設けられている。当該ガイド溝１６ｅの終端は、当接部９として機能する。尚、ガイド溝１６ａ，１６ｂの終端は、それぞれ係止部１６ｃ，１６ｄとして機能する。
【００６５】
また中央の係止穴５１は溝状である。係止穴５１には天井部７３が設けられているが、当該天井部７３には長手方向に延びる二本のスリット７５が形成されている。
さらにベース７１の係止穴５１の両側部にもスリット７６が形成されている。これらのスリット７５，７６は、係止穴５１を構成する壁７２の変形を容易にするために形成されたものである。係止穴５１を構成する壁７２は、スリット７５，７６が設けられているため、中央部分が変形し易く、両端に向かうに従って変形し難い。
【００６６】
またベース板７１には、４個の円柱状突起７７が設けられている。円柱状突起７７は、長手方向の両端部であって、係止穴５１を構成する壁７２の側面近傍に設けられている。
【００６７】
ベース板７１の四隅の部位には、レール５の凸条２２に係止される係合部５７が設けられている。
【００６８】
本実施形態で採用するガイド部材７０は、衝撃を少なくするための工夫として、ガイド溝１６ａ，ガイド溝１６ｅの溝幅が一様ではなく、奥に行くほど狭くなる様に構成されている。
すなわち本実施形態で採用するガイド部材７０では、ガイド溝１６ａは極ゆるやかなテーパ形状となっており、開口部分から奥方向に向かって溝幅が序々に狭くなっている。開口部分（開口端の切り欠かれた部分を除く）と最奥部との幅の相違は、０．５ｍｍ程度である。
【００６９】
またガイド溝１６ａと同一直線上にあるガイド溝１６ｅも同様であり、極ゆるやかなテーパ形状となっており、開口部分から奥方向に向かって溝幅が序序に狭くなっている。
ガイド溝１６ａ，１６ｅを構成する辺７４はベース板７１の大部分に対して片持ち状であるため、ガイド溝１６ａ，１６ｅは開放側が奥側に比べて変形し易い。言い換えると、ガイド溝１６ａ，１６ｅの開放側は奥側に比べて溝幅が拡がり易い。
そのためピン７がガイド溝１６ａ，１６ｅに入ったときのピン７とガイド溝１６ａ，１６ｅとの接触力は、ピン７がガイド溝１６ａ，１６ｅの奥と係合するほど強い。
本実施形態の引戸では、ガイド溝１６ａにテーパが設けられている点と、辺７４が片持ち状である点が相まって、ピン７がガイド溝１６ａ，１６ｅと係合する際に両者の間で摩擦力が発生し、当該摩擦力は、ピン７がガイド溝１６ａ，１６ｅの開放側にある時に弱く、奥側に向かうに従って増大する。
【００７０】
さらに中央に設けられた係止穴５１は、中央部の幅が広く、両端側に向かうに従って溝幅が序々に狭くなっている。
また前記した様に、本実施形態では、係止穴５１を構成する壁７２の近傍にスリット７６が設けられており、さらに天面にもスリット７５が設けられているため、当該壁７２は中央部分がより撓み易い。したがって、ピン７が係止穴５１内を移動する際、両者の間で摩擦力が発生し、当該摩擦力は、ピン７が係止穴５１の両端部にある時に強く、中央部にある時は小さい。
【００７１】
これに対して最も長いガイド溝１６ｂは、いずれの部位も幅が一定である。
【００７２】
ガイド部材７０は、図１２の様に、レール５の凸条に係合部５７が係止され、レール５に沿って移動するが、本実施形態では、レール５の天壁５ａに設けられた鉤状の突起７９が円柱状突起７７と当接し、ガイド部材７０のガタ付きを無くする工夫がなされている。
【００７３】
また本実施形態においても、戸板部材１０，２０，３０にピン７ａ，７ｂが挿着されるが、ピン７ａ，７ｂと一体となっている収納部材には、外周面に微小な突起８０が設けられており、戸板部材１０，２０，３０のピン収納穴８と強固に結合している。
【００７４】
次に、本実施形態の引戸の作用について説明する。
即ち、図９に示したガイド部材７０を使用した場合の各部材の開扉位置における位置関係は、図１３（イ）の通りであり、第１の戸板部材１０の一方のピン７ａは、一方のガイド部材７０ａのガイド溝１６ｂの終端の係合部１６ｄに位置し、他方のピン７ｂは、他方のガイド部材７０ｂのガイド溝１６ｅの当接部９に位置し、第３の戸板部材３０の一方のピン７ａは一方のガイド部材７０ａの当接部９に位置し、他方のピン７ｂは、他方のガイド部材７０ｂのガイド溝１６ｂの終端の係止部１６ｄに位置する。
また中間部にある第２戸板部材２０のピン７ａ，７ｂと、ガイド部材７０ａ，７０ｂとの関係は、図１３（イ）の様に、ピン７ａ，７ｂが長穴状の係止穴５１ａ，５１ｂの外側端部に位置している。
【００７５】
そして、閉扉すべく外側にある第１の戸板部材１０を右側へ移動させると、先の例と同様に、第１の戸板部材１０のみが移動する。移動の初期において、第１の戸板部材１０に設けられたピン７ａ，７ｂは、ガイド部材７０ａのガイド溝１６ｂ及びガイド溝１６ｅを離れる。ここで本実施形態においては、ガイド溝１６ｂは、いずれの部位も溝幅が等しいので、戸板部材１０を右側へ移動させる際の摩擦は少なく、大きな抵抗は無い。またガイド溝１６ｅは、テーパが設けられていて、開口側に向かって広がっているので、ピン７ｂがガイド溝１６ｅを離脱する際にも抵抗は無い。
【００７６】
そして一方のピン７ａは他方のガイド部材７０ｂに達し、遂には図１３（ロ）の様にピン７ａは他方のガイド部材７０ｂのガイド溝１６ａに入ってガイド溝１６ａの終端部たる係合部１６ｃに至る。ここでピン７ａが入って行くガイド溝１６ｂは、前記した様にテーパ形状となっており、奥へ行くほど幅が狭い。またピン７ａとガイド溝１６ａとの接触力は、ピン７ａがガイド溝１６ａの奥の部位と係合するほど強くなる。そのためピン７ａがガイド溝１６ａに入る際に、ピン７ａとガイド溝１６ａの間で摩擦が発生し、さらに当該摩擦力は、ピン７ａがガイド溝１６ａの奥に進むほど強くなる。そのため適度のブレーキが掛かりピン７ａがガイド溝１６ａの終端部の係止部１６ｃと当接する時の衝撃は少なく、騒音の発生も無い。
【００７７】
そしてさらに第１の戸板部材１０を閉扉方向に移動させると、図面右側では、第２の戸板部材２０のピン７ｂが係止穴５１ｂに沿って相対移動し、第２の戸板部材２０を残してガイド部材７０ｂだけが第２の戸板部材２０に対して進行方向に移動する。
ここで係止穴５１は、中央部の幅が広いので、ガイド部材７０ｂの係止穴５１ｂの外側端部がピン７ｂが離れる時に抵抗は無い。更に、第１の戸板部材１０を移動させると、ガイド部材７０ｂの係止穴５１ｂの内側端部がピン７ｂと当接する。
ここで係止穴５１は、端側に向かうに従って溝幅が序々に狭くなっており、且つ端側に向かうに従って係止穴５１が変形し難いので、係止穴５１の内側端部がピン７ｂと当接する間に摩擦が発生し、当該摩擦はピン７ｂが係止穴５１の端部に近づくほど増加する。そのため適度のブレーキが掛かり、当該内側端部がピン７ｂと当接する際の衝撃は小さい。
【００７８】
そして更に第１の戸板部材１０を移動させると、第２の戸板部材２０の７ｂは、ガイド部材７０ｂの係止穴５１ｂの内側端部と接しているため第２の戸板部材２０が第１の戸板部材１０に引っ張られて移動する。
【００７９】
この時、図面左側の左枠２ａ側においては、図１３（ニ）の様に第２の戸板部材２０のピン７ａが係止穴５１ａに沿って相対移動する。即ち、ガイド部材７０ａは停止したままの状態で、第２の戸板部材２０だけが引っ張られて移動し、係止穴５１ａの長さ分だけ移動する。そしてピン７ａが溝状の係止穴５１ａの内側端部と接する。
この時も係止穴５１は、端側に向かうに従って溝幅が序々に狭くなっているので、内側端部がピン７ａと当接する間に適度のブレーキが掛かり、内側端部がピン７ａと接する際の衝撃は小さい。
【００８０】
更に第１の戸板部材１０を移動させると、第２の戸板部材２０は第１の戸板部材１０と一体的に移動する。
そして遂には第１の戸板部材１０の端部が右の縦枠２ｂに当接すると共に、各戸板部材１０，２０，３０同士が互いにずれることにより、前記開口部１を閉塞する閉扉位置となり、押入れの開口部１は完全に閉塞される（図１３ホ参照）。
本実施形態においても、中間部にある第２戸板部材２０のピン７ａ，７ｂと、ガイド部材７０ａ，７０ｂとの関係は、開扉位置における場合に比べてガイド部材７０ａ，７０ｂが第２戸板部材２０の幅方向に離れたものとなる。
【００８１】
閉扉された押入れの開口部１を開扉する場合は、同様に図１４（イ）の状態にある第１の戸板部材１０を左の方へ移動させるが、開口部１を開扉する場合についても、衝撃は小さい。
すなわち開口部１を開扉する場合は、先の実施形態と同様に戸板部材１０を左の方へ移動させる。第１の戸板部材１０の一方のピン７ａは、他方のガイド部材７０ｂのガイド溝１６ａ内を摺動するため、第１の戸板部材１０のみが移動する。ここでガイド溝１６ａには、開口側に向かって広がるテーパが設けられているので、ピン７ａがガイド溝１６ａを離脱する際の抵抗は無い。
【００８２】
そして第１の戸板部材１０の他方のピン７ｂは、他方のガイド部材７０ｂのガイド溝１６ｅに入り、図１４（ロ）の様に当接部９に係止する。この時、ガイド溝１６ｅは、テーパ形状となっており、奥へ行くほど幅が狭く、且つガイド溝１６ｅの辺７４が片持ち状であるため、ピン７ｂの移動中に摩擦が発生し、さらにピン７ｂが奥側に移動するにつれて摩擦力が増大する。そのため戸板部材１０には適度のブレーキが掛かる。従って、ピン７ｂが当接部９に係止する際の衝撃は小さい。
【００８３】
そして戸板部材１０をさらに移動させると、中間の戸板部材２０が停止した状態で、右側のガイド部材７０ｂだけが押されて移動する。すなわちガイド部材７０ｂが中間の戸板部材２０と係合する係止穴５１は溝状であるから、ガイド部材７０ｂの係止穴５１の他端側（外側端部）が中間の戸板部材２０のピン７ａと当接するまで、戸板部材２０は停止した状態を維持し、戸板部材１０と右側のガイド部材７０ｂが一体的に移動する。言い換えると、図１４（ハ）の状態となるまで中間の戸板部材２０が停止した状態を維持し、戸板部材１０と右側のガイド部材７０ｂが一体的に移動する。
尚、前記した様に係止穴５１は、端側に向かうに従って溝幅が序々に狭くなっていると共に、係止穴５１は端部に向かうほど変形し難くなるので、外側端部がピン７ｂと当接する間に摩擦力が発生し、当該摩擦力は、ピン７ｂが端部に近づくほど増大する。そのため戸板部材１０には適度のブレーキが掛かり、係止穴５１の外側端部がピン７ｂと当接する際の衝撃は小さい。
係止穴５１の外側端部がピン７ｂと当接した時、第１の戸板部材１０と第２の戸板部材２０とは、互いに重合した状態となる。
【００８４】
そしてさらに戸板部材１０を移動させると、戸板部材１０が、ガイド部材７０ｂの当接部９と係合し、さらにガイド部材７０ｂの係止穴５１と中間の戸板部材２０のピン７ｂが係合するため、戸板部材２０は戸板部材１０に押されて共に移動する。一方、戸板部材２０の左側、すなわちピン７ａ側は、左側のガイド部材７０ａの係止穴５１内を移動する。そしてピン７ａは係止穴５１ａの内側端部を離れ、外側端部がピン７ａと当接する。
ここで係止穴５１は、端側に向かうに従って溝幅が序々に狭くなっているので、ピン７ａが係止穴５１の外側端部が当接する間に適度のブレーキが掛かり、当接の際の衝撃は小さい。
【００８５】
この状態で更に第１の戸板部材１０をさらに左に移動させると、第２の戸板部材２０及びガイド部材７０ａ，７０ｂが共に移動し、第３の戸板部材３０の他方のピン７ｂが、一方のガイド部材７０ａのガイド溝１６ａから離脱し、他方のガイド部材７０ｂのガイド溝１６ｂに入る。
従って、各戸板部材１０，２０，３０は、それぞれ重合した状態でそれぞれの端部が左の縦枠２ａに当接した開扉位置となり、押入れの開口部１は完全に開扉される。
【００８６】
以上、図９〜１４を参照しつつ説明した実施形態では、ガイド溝１６ａ，１６ｅの溝幅を奥に行くほど狭くなるものとした。この構成は、ピン７がガイド溝１６ａ，１６ｅの奥側に行くほど、両者の摩擦力が増大する様に工夫したものであり、推奨される構成である。しかしながら前記した実施形態では、ガイド溝１６ａ，１６ｅの弾性力によって、ピン７とガイド溝１６ａ，１６ｅとの接触力が奥に行くほど増大するので、ガイド溝１６ａ，１６ｅの溝幅は、必ずしも奥に行くほど狭くなっていなくても、両者の摩擦力は奥側に行くほど増大することとなる。
【００８７】
以上説明した実施形態では、いずれも戸板部材が３枚の場合について説明したが、４枚以上であっても、上記の実施の形態と同様に実施することができる。さらに、引戸はクロゼットのような押入れに限定するものではなく、各種の部屋の間仕切りなどにも使用することができる。
【００８８】
【発明の効果】
この発明によれば、３以上の戸板部材が相互に関連してレールに沿って移動するため、基本的に１の戸板部材を移動させるだけで、開扉及び閉扉させることができる。従って、この発明の引戸は開扉及び閉扉のための使い勝手が向上する。また、この発明の引戸がクロゼットのような押入れに使用されると、扉が押入れの開口部から突出しないため、押入れの前にベッドのような家具を置くことも可能になり、部屋のレイアウトが自由になるという効果が発揮される。
【００８９】
しかも、レールには、別体のガイド部材が戸板部材の移動方向の両側にそれぞれ設けられているので、戸板部材の移動方向の長さとは無関係にガイド部材を設けることができる。従って、開口部の大きさに応じて戸板部材の幅長が異なっても一定の形状のガイド部材を兼用でき、ガイド部材をユニット化することが可能となり、その汎用性が高くなる。
【００９０】
更に、別体の一対のガイド部材を使用するため、ガイド部材をレールの全長に設ける必要がなく、ガイド部材の軽量化と材料コストの削減を図ることも可能となる。
【００９１】
また、ガイド部材は、レールに内蔵されているので、外部から見えにくく、部屋の雰囲気を壊さない効果がある。
【００９２】
また特に請求項３に記載の引戸では、ガイド溝に設けられた係止部の位置をずらし、係止部の位置がガイド溝の開放側よりにある方の係止部の背後側にもう一つの当接部を設けたので、引戸は当該当接部によっても押し動かされる。そのため本発明の引戸は、動作が円滑である。
【００９３】
また特に請求項４に記載の引戸では、ガイド部材は、第２の戸板部材に対して戸板部材の移動方向に相対移動可能に取り付けられているので、戸板部材を広げて押入れ等を開いた時に、ガイド部材と戸板部材の位置関係がずれ、押入れ等を閉じた時の戸板部材同士の重なり部分が減少する効果がある。
【００９４】
さらに請求項５に記載の引戸では、ガイド溝の幅が係合部材の幅よりも狭く、両者の間に摩擦が発生するので、引戸に適度のブレーキがかかり、騒音が抑制される。
【００９５】
また特に請求項６に記載の引戸では、第１又は第３の戸板部材の係合部材が当該ガイド溝と係合したとき、溝の奥側において両者の間により強い摩擦が発生し戸板部材にブレーキが掛かる。そのため本発明の引戸では、戸板部材を勢いよく操作しても、戸板部材同士が所定の位置関係となる際に、戸板部材に適度のブレーキがかかり、騒音が抑制される。
【００９６】
また特に請求項７に記載の引戸では、ガイド部材の中間係合部が溝状であり、第２の戸板部材のピンは前記溝に係合し、ピンが溝の両端側にある時にピンと溝との間で摩擦が発生する。そのため本発明の引戸では、戸板部材を勢いよく操作しても、戸板部材同士が所定の位置関係となる際に、戸板部材に適度のブレーキが掛かり、騒音が抑制される効果がある。
【００９７】
特に請求項８に記載の引戸の様に、ガイド部材の両側には、前記レールの側面に形成された被係止部に係止する係合部がそれぞれ突設され、各ガイド部材には、係合部を被係止部に係止する際に、両方の係合部の幅長を小さくするための切欠部が形成されている場合には、例えば、枠体に既に取り付けられているレールに、各ガイド部材をワンタッチで簡単に着脱することが可能となる利点がある。
【００９８】
さらに請求項９に記載の引戸用ガイド部材では、複数の引戸を関連付けて動作させることができ、かつその動きが円滑であるという効果がある。

BACKGROUND OF THE INVENTION
  The present invention particularly relates to a sliding door used for opening and closing an opening of a closet such as a closet.And sliding door guideIt is about.
[0002]
[Prior art]
  The opening of the closet is generally opened and closed by a foldable door. For example, as shown in FIG. 15, the folding door has a structure in which four doors 100 that are bent two by two are divided and opened on both sides from the center of the opening 1 of the closet. Therefore, the opened door 100 is in a state of protruding from the opening 1 of the closet.
[0003]
[Problems to be solved by the invention]
  By the way, because of the layout of the room, you may want to place furniture such as a bed before a closet like a closet. However, when the opening 1 of the closet is opened and closed by the foldable door 100, the opened door 100 projects outward from the opening 1 of the closet, and thus furniture cannot be placed in front of the door 100.

The sliding door has a first opening, a second and third door plate members 10, 20, and 30 for opening a closet 1 such as a closet. It opens and closes. The close-up opening 1 is formed by left and right vertical frames 2a and 2b and upper and lower frames (only the upper frame 4a is shown).
[0027]
  As shown in FIG. 2, an elongate rail 5 comprising a top wall 5a and both side walls 5b is attached to the lower surface of the upper frame 4a of the closet with screws 6, and each door plate member 10, 20, 30 is attached to this rail. 5 can move along each of them.
[0028]
  As shown in FIG. 2, pin accommodation holes 8 are formed in the vertical direction on the upper surface of each door plate member 10, 20, 30 and on both sides in the moving direction. In each pin storage hole 8, a storage member 12 and a pin 7 combined in advance are inserted. For the description of the embodiment, a pin disposed on one of the door plate members 10, 20, and 30 (left side in FIG. 1) is a pin 7a, and the other is a 7b.
  That is, each pin storage hole 8 is fitted with a bottomed cylindrical storage member 12 having an open top surface. In each storage member 12, a pair of pins 7a and 7b as engaging members are provided so as to protrude and retract. Each pin 7a, 7b is urged by a spring 13 housed in the housing member 12 in a direction protruding upward.
[0029]
  As shown in FIG.In the rail 5, a pair of left and right guide members 11a and 11b for moving the first, second and third door plate members 10, 20, and 30 in relation are incorporated. Both guide members 11a and 11b have the same shape and are arranged in a state of point symmetry with respect to each other.
[0030]
  When one guide member (left side member shown in FIG. 1) 11a is described as an example, a locking hole (intermediate engagement portion) 15 is formed at the center in the width direction of the guide member 11a. The locking hole 15 is a round hole, and one pin 7a of the second door plate member 20 located in the middle of the sliding door is inserted into the locking hole 15 from below.
  In addition, the guide member 11a is formed with a contact portion 9 formed by cutting out an inner corner portion at one end side so that the pin 7a of the third door plate member 30 inside the press-in portion is locked.
  Further, on the lower surface of the guide member 11a and on the side of the locking hole 15, a guide groove having a long groove shape is formed along a straight line (hereinafter referred to as a straight line) in the moving direction of the door plate member with respect to the contact part 9. 16a is formed. The end portion of the guide groove 16a is located in the vicinity of the contact portion 9, and the other end is opened and opened so that the upper end of the other pin 7b of the third door plate member 30 can be inserted and removed. .
  In addition, the back part (end part) of the guide groove 16a is obstruct | occluded, and the said innermost part functions as the latching | locking part 16c.
[0031]
  Furthermore, a long groove-like guide groove 16b parallel to the guide groove 16a is formed outside the locking hole 15 in the guide member 11a. One end of the guide groove 16b is juxtaposed with the locking hole 15, and the other end is opened and opened so that the upper end of one pin 7a of the front first door plate member 10 can be inserted and removed. .
  One end of the guide groove 16b, that is, the innermost part is closed, and the innermost part functions as a locking part 16d.
  Comparing the guide grooves 16a and 16b, the former guide groove 16a is shorter in length than the latter guide groove 16b because the corner portion is cut away to form the contact portion 9. Moreover, the latching | locking part 16c, 16d has shifted | deviated to the moving direction of the doorplate members 10,20,30. And the relationship between each latching | locking part 16c, 16d and the contact part 9 is as follows of the latching | locking part 16c of the one near the open side among two guide grooves 16a, 16b.Vertical frame 2aA contact portion 9 is provided on the side.
[0032]
  On the other end side of the guide member 11a and on the straight line of both the guide grooves 16a and 16b, a guide surface is inclined from the upper surface of the guide grooves 16a and 16b of the guide member 11a toward the lower surface of the top wall 5a of the rail 5. Guide portions 19 having 18 are provided in a protruding manner.
[0033]
  Further, engaging portions 23 are provided on both sides of the guide member 11a, and the engaging portions 23 are engaged with ridges 22 as engaged portions protruding on the inner surfaces of both side walls 5b of the rail 5. Stopped. The guide member 11a is engaged with the engaging portion 23 so as to be movable along the rail 5 without dropping. Further, the guide member 11a is formed with a notch 24 in the direction along the rail 5 from the other end side so that the width of both engaging portions 23 can be narrowed as shown in FIG. Accordingly, by pressing both sides of the guide member 11a inward against the elastic force of the guide member 11a, the width of both the locking portions 23 can be made narrower than the interval between the ridges 22 of the rail 5, and the guide member 11a. Can be easily attached to the rail 5.
[0034]
  The one guide member 11a and the other guide member 11b having the same shape as that of the first guide member 11a have pins 7a and 7b of the second door plate member 20 locked in the locking holes 15, and both guide members 11a and 11b. Does not move relative to the second door plate member 20.
[0035]
  The sliding door of the present embodiment is configured as described above, and the operation thereof will be described next.
  First, as shown in FIG. 5 (a), the first, second, and third door plate members 10, 20, and 30 are gathered together on the left vertical frame 2a of the opening 1 of the closet and overlap each other to form the opening. 1 is in the open position to open. At this time, the one pin 7a of the first door plate member 10 is positioned at the terminal locking portion 16d of the guide groove 16b of the one guide member 11a, and the other pin 7b is in contact with the other guide member 11b. Located in section 9.
[0036]
  In addition, one pin 7a of the third door plate member 30 is located at the contact portion 9 of the one guide member 11a, and the other pin 7b is a locking portion at the end of the guide groove 16b of the other guide member 11b. 16d.
[0037]
  And when closing the opening 1 of a closet, the 1st doorplate member 10 which exists outside is moved to the right side. When the first door plate member 10 moves, one pin 7a of the first door plate member 10 slides in the guide groove 16b of one guide member 11a, and the other pin 7b is a contact portion. 9, only the first door plate member 10 is moved, and the other second and third door plate members 10 and 20 are in a stopped state.
[0038]
  One pin 7a reaches the guide surface 18 of the guide portion 19 from the guide groove 16b with the movement of the first door plate member 10, but the spring 13 biases the pin 7a in the protruding direction. Gradually protrudes while sliding on the guide surface 18 of the guide portion 19 and comes into contact with the lower surface of the top wall 5a of the rail 5 with almost no impact (see FIG. 3).
[0039]
  Further, when the first door plate member 10 moves, one pin 7a reaches the other guide member 11b, but the other guide member 11b is also provided with a guide portion 19 in the same manner as the one guide member 11b. Therefore, one pin 7a can smoothly transfer to the other guide member 11b via the guide portion 19. The pin 7a sliding on the guide surface 18 of the guide portion 19 gradually recedes against the elastic force of the spring 13, enters the guide groove 16a of the other guide member 11b, and locks the end of the guide groove 16a. It reaches part 16c and engages (see FIG. 5B).
[0040]
  Further, when the first door plate member 10 is moved, one pin 7a engaged with the guide groove 16a of the other guide member 11b moves the other guide member 11b. Since this guide member 11b cannot move relative to the second door plate member 20, the second door plate member 20 is pulled by the first door plate member 10 and moved.
[0041]
  At the initial stage of the movement of the second door plate member 20, the guide groove 16b of the other guide member 11b moves with respect to the other pin 7b of the third door plate member 30, and one pin 7a is one guide member. Since the guide members 11a and 11b move together with the second door plate member 20 to detach from the contact portion 9 of 11a, the third door plate member 30 is in a stopped state.
[0042]
  The other pin 7b of the third door plate member 30 is disengaged from the guide groove 16b of the other guide member 11b (see FIG. 5C), but as described above, the pin 7b is made smooth without impact by the guide portion 19. Move to the rail 5 side. Further, the other pin 7b enters the guide groove 16a via the guide portion 19 of the one guide member 11a.
[0043]
  Accordingly, the end portion of the first door plate member 10 abuts on the right vertical frame 2b, and the door plate members 10, 20, and 30 are displaced from each other, so that the opening portion 1 is closed, and the close-up position is closed. The opening 1 is completely closed (see FIG. 5D).
[0044]
  Next, the case where the closed opening 1 of the closet is opened will be described. When the first door plate member 10 in the state of FIG. 6 (a) is moved to the left, one pin 7a of the first door plate member 10 slides in the guide groove 16a of the other guide member 11b. Therefore, only the first door plate member 10 moves.
[0045]
  The one pin 7a moves along the rail 5 from the other guide member 11b via the guide portion 19, and then slides in the guide groove 16b of the one guide member 11a and engages with the locking portion 16d at the end thereof. Stop. Further, the other pin 7b of the first door plate member 10 is engaged with the contact portion 9 of the other guide member 11b. At this time, the first door plate member 10 and the second door plate member 20 are superposed on each other (see FIG. 6B).
[0046]
  When the first door plate member 10 is further moved to the left in this state, the second door plate member 20 is also moved simultaneously through both guide members 11a and 11b. That is, in the present embodiment, the second door plate member 20 has the locking portions 16d and the contact portions 9 of the guide members 11a and 11b provided at both ends thereof engaged with the pins 7a and 7b of the door plate member 10, respectively. The member 20 engages with the door plate member 10 at both ends thereof. Therefore, if the 1st doorplate member 10 is moved to the left, the doorplate member 20 will also move with sufficient balance.
  The other pin 7b of the third door plate member 30 enters the guide groove 16b of the other guide member 11b after being separated from the guide groove 16a of the one guide member 11a (see FIG. 6C).
  Accordingly, the door plate members 10, 20, and 30 are in an overlapped state with their respective end portions in contact with the left vertical frame 2a, and the opening 1 of the closet is completely opened.
[0047]
  The sliding door is opened and closed by moving the first door plate member 10 left and right, but can also be similarly moved by moving the third door plate member 30 left and right.
  That is, each door plate member 10, 20, 30 is located on the right vertical frame 2b side opposite to the above in the door open position state. And if the 3rd doorplate member 30 is moved to the left side, after only this 3rd doorplate member 30 will move first, the other pin 7b of the 3rd doorplate member 30 will engage with one guide member 11a. Therefore, the second door plate member 20 is also moved simultaneously, and the door plate members 10, 20, and 30 are in the closed position.
[0048]
  On the other hand, when opening the closed opening 1 of the closet, if the third door plate member 30 is moved to the right, only the third door plate member 30 becomes the second door plate member 20. Since the other pin 7b of the third door plate member 30 engages with the other guide member 11b, the second door plate member 20 moves together with the third door plate member 30, The door plate members 10, 20, and 30 are the opening positions where they overlap.
[0049]
  Further, when closing the opening 1, the first door plate member 10 is moved to close the opening 1, and when closing the opening 1, the third door plate member 30 is moved. It is also possible to open the door.
[0050]
  In addition, this invention is not limited to said embodiment. For example, the abutting portions 9 of both the guide members 11a and 11b do not necessarily need to be engaged with the pins 7a and 7b of the first and third door plate members 10 and 30, and allow the pins 7a and 7b to escape. It may be a notch for relief. In such a case, there is an advantage that the first, second and third door plate members 10, 20, 30 can have the same structure.
[0051]
  In the above-described embodiment, a round hole-like locking hole 15 is provided in the middle portion of the guide members 11a and 11b, and the pins 7a and 7b of the door plate member 20 are engaged to guide the members 11a and 11b and the second door plate. The structure which integrated the member 20 substantially was shown. Although this structure has an effect that the operation of the door plate member is smooth, the present invention is not particularly concerned with this structure, and may allow relative movement between the second door plate member and the guide member.
[0052]
  FIG. 7 is a perspective view of a guide member employed in another embodiment of the present invention. FIG. 8 is a schematic plan view illustrating a state in which the sliding door is closed from the open state in the embodiment of FIG. 7.
  The guide member 50 shown in FIG. 7 has substantially the same configuration as that of the previous embodiment. In the guide member 11 of the previous embodiment, the locking hole 15 is a round hole. In the guide member 50 of the embodiment, a groove-shaped locking hole 51 is formed. In addition, as shown in FIGS. 7A and 7C, the locking hole 51 is deeper at one end side (an end portion near the center of the guide member 50) than the other portion, and the portion includes the deep hole portion 53. It has become.
[0053]
  Further, the guide member 50 is different in that the notch of the guide portion 55 is longer than that of the previous embodiment and that the deep hole portion 56 is provided at the end of the guide groove 16a. The reason why the deep hole portions 53 and 56 are provided at the terminal ends of the locking hole 51 and the guide groove 16a is that the pins 7a and 7b are inserted into the deep hole portions 53 and 56, so that a feeling of moderation is generated and the usability is felt. This is for the purpose of improving. In the present embodiment, the deep hole portion 56 at the end of the guide groove 16a functions as a locking portion.
[0054]
  Furthermore, the guide member 50 is different from the previous example in that the engaging portions 57 that are locked to the ridges 22 of the rail 5 are provided at two locations. Same as that in the example.
  In FIG. 7 (a), the dent indicated by 58 is caused by molding requirements and has no functional meaning.
[0055]
  When the guide member 50 shown in FIG. 7 is used, when the door plate member is arranged at the closed position, there is a specific effect that the overlap between the door plate members is small.
[0056]
  That is, when the guide member 50 shown in FIG. 7 is used, the positional relationship of each member at the door opening position is as shown in FIG. 8 (a), and one pin 7a of the first door plate member 10 is The other pin 7b is located at the contact portion 9 of the other guide member 50b, and one pin 7a of the third door plate member 30 is one guide member. The other pin 7b is located at the end of the guide groove 16b of the other guide member 50b.
  Further, the relationship between the pins 7a and 7b of the second door plate member 20 in the intermediate portion and the guide members 50a and 50b is as shown in FIG. 8 (a), and the pins 7a and 7b are groove-shaped locking holes (intermediate). (Engagement portion) 51a, 51b is located at the outer end.
[0057]
  When the first door plate member 10 located outside is moved to the right to close the door, only the first door plate member 10 moves as in the previous example, and one pin 7a is moved in the same manner as in the previous example. The other guide member 50b is reached, and finally the pin 7a enters the guide groove 16a of the other guide member 50b and reaches the locking portion 16c, which is the terminal portion of the guide groove 16a (FIG. 8B).
[0058]
  Here, in this embodiment, since the locking holes 51a and 51b provided in the intermediate door plate member 20 are groove-shaped and have a length, when the first door plate member 10 is further moved in the door closing direction, The pin 7b of the second door plate member 20 moves relative to the locking hole 51b, and only the guide member 50b moves in the traveling direction with respect to the second door plate member 20, leaving the second door plate member 20.
  Further, when the first door plate member 10 is moved, the inner end portion of the locking hole 51b of the guide member 50b comes into contact with the pin 7b and the pin 7b engages with the deep hole portion 53 as shown in FIG. To do.
[0059]
  When the first door plate member 10 is further moved, the second door plate member 20 is in contact with the inner end portion of the locking hole 51b of the guide member 50b, so that the second door plate member 20 moves the guide member 50b. Pulled through. Therefore, the second door plate member 20 moves by being pulled by the first door plate member 10.
[0060]
  At this time, on the left frame 2a side on the left side of the drawing, only the second door plate member 20 moves as shown in FIG. 8 (d), and the pin 7a relatively moves along the locking hole 51a. That is, while the guide member 50a remains stopped, only the second door plate member 20 moves by the length of the locking hole 51a. Then, the pin 7 a comes into contact with the inner end portion of the elongated hole-shaped locking hole 51 a, and the pin 7 a engages with the deep hole portion 53.
[0061]
  When the first door plate member 10 is further moved, the second door plate member 20 moves integrally with the first door plate member 10.
  Finally, the end portion of the first door plate member 10 abuts on the right vertical frame 2b, and the door plate members 10, 20, and 30 spread out of each other, thereby closing the opening 1. The opening 1 of the closet is completely closed (see FIG. 8E).
[0062]
  In the closed state, the relationship between the pins 7a and 7b of the second door plate member 20 in the middle portion and the guide members 50a and 50b is such that the guide members 50a and 50b are compared with the case of the door opening position of the previous embodiment. 50 b is separated in the width direction of the second door plate member 20. As a result, the overlap between the first door plate member 10 and the second door plate member 20 and the overlap between the second door plate member 20 and the third door plate member 30 are smaller than in the previous example.
  In the example described above, the pin 7a, 7b of the door panel members 10, 20, 30 adjacent to each other at the door closing position intersects as shown in FIG. In the present embodiment, it can also be understood from being arranged on a straight line as shown in FIG.
[0063]
  Next, another embodiment will be described.
  FIG. 9 is a perspective view of a guide member employed in another embodiment of the present invention. FIG. 10 is a front view and a plan view of the guide member of FIG. FIG. 11 is an explanatory view showing the groove width of the guide groove of the guide member of FIG. FIG. 12 is a cross-sectional view showing the relationship between a rail, a guide, and a door plate member. (A)-(e) of FIG. 13 is a schematic plan view which respectively shows the state which closes a sliding door from an open state. (A)-(e) of FIG. 14 is a schematic plan view which respectively shows the state which opens a sliding door from a closed state.
[0064]
  In the embodiment described above, the guide grooves 16a and 16b are both of which the top surface is closed, whereas the guide member 70 of the present embodiment is different in that the top surface is open.
  That is, the guide member 70 has two rows of guide grooves 16a and 16b on the left and right sides, and one end side of these guide grooves 16a and 16b is opened as in the previous embodiment. Each of the guide grooves 16a and 16b is constituted by a wall 72 standing from a plate-like base 71, and the top surface of each part is open.
  The guide grooves 16a and 16b are short in one guide groove 16a and long in the other as in the previous embodiment, but another guide groove 16e is provided on the back side of the row of the shorter guide grooves 16a. Yes. The terminal end of the guide groove 16e functions as the contact portion 9. The terminal ends of the guide grooves 16a and 16b function as locking portions 16c and 16d, respectively.
[0065]
  The central locking hole 51 has a groove shape. A ceiling portion 73 is provided in the locking hole 51, and two slits 75 extending in the longitudinal direction are formed in the ceiling portion 73.
  Further, slits 76 are formed in both side portions of the locking hole 51 of the base 71. These slits 75 and 76 are formed to facilitate the deformation of the wall 72 constituting the locking hole 51. Since the wall 72 constituting the locking hole 51 is provided with the slits 75 and 76, the central portion is easily deformed and is hardly deformed toward both ends.
[0066]
  The base plate 71 is provided with four columnar projections 77. The columnar protrusions 77 are provided at both ends in the longitudinal direction and in the vicinity of the side surface of the wall 72 constituting the locking hole 51.
[0067]
  At the four corners of the base plate 71, engaging portions 57 that are locked to the ridges 22 of the rail 5 are provided.
[0068]
  As a device for reducing the impact, the guide member 70 employed in the present embodiment is configured such that the groove widths of the guide groove 16a and the guide groove 16e are not uniform and become narrower toward the back.
  That is, in the guide member 70 employed in the present embodiment, the guide groove 16a has an extremely gentle taper shape, and the groove width gradually decreases from the opening portion toward the back. The difference in width between the opening portion (excluding the portion where the opening end is cut out) and the innermost portion is about 0.5 mm.
[0069]
  The same applies to the guide groove 16e on the same straight line as the guide groove 16a, and has an extremely gentle taper shape, and the groove width gradually narrows from the opening portion toward the back.
  Since the sides 74 constituting the guide grooves 16a and 16e are cantilevered with respect to most of the base plate 71, the open sides of the guide grooves 16a and 16e are more easily deformed than the back side. In other words, the groove width of the open side of the guide grooves 16a and 16e is easier to expand than the back side.
  Therefore, the contact force between the pin 7 and the guide grooves 16a and 16e when the pin 7 enters the guide grooves 16a and 16e is so strong that the pin 7 engages with the back of the guide grooves 16a and 16e.
  In the sliding door of this embodiment, the point where the taper is provided in the guide groove 16a and the point where the side 74 is cantilevered are combined, and when the pin 7 engages with the guide grooves 16a and 16e, the gap between the two is reached. A frictional force is generated, and the frictional force is weak when the pin 7 is on the open side of the guide grooves 16a and 16e, and increases toward the back side.
[0070]
  Furthermore, the locking hole 51 provided in the center has a wide central portion, and the groove width gradually decreases toward both ends.
  Further, as described above, in this embodiment, since the slit 76 is provided in the vicinity of the wall 72 constituting the locking hole 51 and the slit 75 is also provided on the top surface, the wall 72 is formed at the center. The part is more flexible. Therefore, when the pin 7 moves in the locking hole 51, a frictional force is generated between them, and the frictional force is strong when the pin 7 is at both ends of the locking hole 51 and when the pin 7 is at the center. Is small.
[0071]
  On the other hand, the longest guide groove 16b has a constant width at any part.
[0072]
  As shown in FIG. 12, the guide member 70 is moved along the rail 5 with the engaging portion 57 locked to the protrusions of the rail 5. In this embodiment, the guide member 70 is provided on the top wall 5 a of the rail 5. A contrivance is made so that the hook-shaped protrusion 79 abuts on the cylindrical protrusion 77 and the guide member 70 is not rattled.
[0073]
  Also in this embodiment, the pins 7a and 7b are inserted into the door plate members 10, 20, and 30, but the storage member integrated with the pins 7a and 7b is provided with minute protrusions 80 on the outer peripheral surface. It is firmly coupled to the pin housing holes 8 of the door plate members 10, 20, and 30.
[0074]
  Next, the effect | action of the sliding door of this embodiment is demonstrated.
  That is, when the guide member 70 shown in FIG. 9 is used, the positional relationship of each member at the door opening position is as shown in FIG. 13 (a), and one pin 7a of the first door plate member 10 is The other pin 7b is located at the contact portion 9 of the guide groove 16e of the other guide member 70b, and is located at the end of the engaging portion 16d of the guide groove 16b of the guide member 70a. One pin 7a is located at the abutting portion 9 of one guide member 70a, and the other pin 7b is located at the locking portion 16d at the end of the guide groove 16b of the other guide member 70b.
  Further, the relationship between the pins 7a and 7b of the second door plate member 20 in the intermediate portion and the guide members 70a and 70b is such that the pins 7a and 7b are elongated holes-like locking holes 51a and 51a, as shown in FIG. It is located at the outer end of 51b.
[0075]
  Then, when the first door plate member 10 on the outer side is moved to the right to close the door, only the first door plate member 10 moves as in the previous example. In the initial stage of the movement, the pins 7a and 7b provided on the first door plate member 10 leave the guide groove 16b and the guide groove 16e of the guide member 70a. In this embodiment, since the guide groove 16b has the same groove width in any part, there is little friction when the door plate member 10 is moved to the right side, and there is no great resistance. Further, since the guide groove 16e is provided with a taper and expands toward the opening side, there is no resistance when the pin 7b leaves the guide groove 16e.
[0076]
  One pin 7a reaches the other guide member 70b, and finally the pin 7a enters the guide groove 16a of the other guide member 70b as shown in FIG. To. Here, the guide groove 16b into which the pin 7a enters is tapered as described above, and the width becomes narrower toward the back. Further, the contact force between the pin 7a and the guide groove 16a becomes stronger as the pin 7a engages with the inner part of the guide groove 16a. Therefore, when the pin 7a enters the guide groove 16a, friction is generated between the pin 7a and the guide groove 16a, and the friction force becomes stronger as the pin 7a moves deeper into the guide groove 16a. Therefore, a moderate brake is applied, and the impact when the pin 7a comes into contact with the engaging portion 16c at the end of the guide groove 16a is small, and no noise is generated.
[0077]
  When the first door plate member 10 is further moved in the door closing direction, on the right side of the drawing, the pin 7b of the second door plate member 20 moves relatively along the locking hole 51b, leaving the second door plate member 20. Only the guide member 70 b moves in the traveling direction with respect to the second door plate member 20.
  Here, since the locking hole 51 has a wide central portion, there is no resistance when the outer end of the locking hole 51b of the guide member 70b is separated from the pin 7b. Further, when the first door plate member 10 is moved, the inner end of the locking hole 51b of the guide member 70b comes into contact with the pin 7b.
  Here, the groove width of the locking hole 51 is gradually narrowed toward the end side, and the locking hole 51 is hardly deformed toward the end side, so that the inner end portion of the locking hole 51 is pin 7b. Friction is generated during contact with the pin, and the friction increases as the pin 7 b approaches the end of the locking hole 51. Therefore, an appropriate brake is applied, and the impact when the inner end portion comes into contact with the pin 7b is small.
[0078]
  When the first door plate member 10 is further moved, 7b of the second door plate member 20 is in contact with the inner end of the locking hole 51b of the guide member 70b, so that the second door plate member 20 is the first door member 20b. The door plate member 10 is pulled and moved.
[0079]
  At this time, on the left frame 2a side on the left side of the drawing, the pin 7a of the second door plate member 20 relatively moves along the locking hole 51a as shown in FIG. 13 (d). That is, while the guide member 70a is stopped, only the second door plate member 20 is pulled and moved, and is moved by the length of the locking hole 51a. The pin 7a contacts the inner end of the groove-shaped locking hole 51a.
  Also at this time, since the groove width of the locking hole 51 is gradually narrowed toward the end side, an appropriate brake is applied while the inner end portion is in contact with the pin 7a, and the inner end portion is in contact with the pin 7a. The impact is small.
[0080]
  When the first door plate member 10 is further moved, the second door plate member 20 moves integrally with the first door plate member 10.
  Finally, the end portion of the first door plate member 10 comes into contact with the right vertical frame 2b, and the door plate members 10, 20, and 30 are displaced from each other, so that the opening portion 1 is closed and the door is closed. The opening 1 is completely closed (see FIG. 13E).
  Also in this embodiment, the relationship between the pins 7a and 7b of the second door plate member 20 in the intermediate portion and the guide members 70a and 70b is such that the guide members 70a and 70b are the second door plate members as compared with the case of the door opening position. 20 apart in the width direction.
[0081]
  When opening the closed opening 1 of the closet, similarly, the first door plate member 10 in the state of FIG. 14 (a) is moved to the left, but the opening 1 is opened. But the impact is small.
  That is, when opening the opening 1, the door plate member 10 is moved to the left as in the previous embodiment. Since one pin 7a of the first door plate member 10 slides in the guide groove 16a of the other guide member 70b, only the first door plate member 10 moves. Here, since the guide groove 16a is provided with a taper that widens toward the opening side, there is no resistance when the pin 7a leaves the guide groove 16a.
[0082]
  The other pin 7b of the first door plate member 10 enters the guide groove 16e of the other guide member 70b and engages with the contact portion 9 as shown in FIG. At this time, the guide groove 16e has a tapered shape, the width is narrower toward the back, and the side 74 of the guide groove 16e is cantilevered, so that friction occurs during the movement of the pin 7b, As the pin 7b moves to the back side, the frictional force increases. Therefore, an appropriate brake is applied to the door plate member 10. Therefore, the impact when the pin 7b is engaged with the contact portion 9 is small.
[0083]
  When the door plate member 10 is further moved, only the right guide member 70b is pushed and moved while the intermediate door plate member 20 is stopped. That is, since the locking hole 51 in which the guide member 70b engages with the intermediate door plate member 20 has a groove shape, the other end side (outer end portion) of the locking hole 51 of the guide member 70b is the pin of the intermediate door plate member 20. Until it contacts 7a, the door plate member 20 maintains a stopped state, and the door plate member 10 and the right guide member 70b move integrally. In other words, the state where the intermediate door plate member 20 is stopped until the state shown in FIG. 14C is maintained, and the door plate member 10 and the right guide member 70b move integrally.
  As described above, the groove width of the locking hole 51 is gradually narrowed toward the end side, and the locking hole 51 becomes difficult to be deformed toward the end portion, so that the outer end portion is pin 7b. Friction force is generated during contact with the pin, and the friction force increases as the pin 7b approaches the end. Therefore, an appropriate brake is applied to the door plate member 10, and the impact when the outer end portion of the locking hole 51 comes into contact with the pin 7b is small.
  When the outer end portion of the locking hole 51 comes into contact with the pin 7b, the first door plate member 10 and the second door plate member 20 are superposed with each other.
[0084]
  When the door plate member 10 is further moved, the door plate member 10 engages with the contact portion 9 of the guide member 70b, and further, the locking hole 51 of the guide member 70b and the pin 7b of the intermediate door plate member 20 engage. Therefore, the door plate member 20 is pushed by the door plate member 10 and moves together. On the other hand, the left side of the door plate member 20, that is, the pin 7a side moves in the locking hole 51 of the left guide member 70a. And the pin 7a leaves | separates the inner side edge part of the locking hole 51a, and an outer side edge part contact | abuts with the pin 7a.
  Here, since the groove width of the locking hole 51 gradually decreases toward the end side, an appropriate brake is applied while the outer end of the locking hole 51 abuts on the pin 7a. The impact is small.
[0085]
  When the first door plate member 10 is further moved to the left in this state, the second door plate member 20 and the guide members 70a and 70b are moved together, and the other pin 7b of the third door plate member 30 is moved to one side. It separates from the guide groove 16a of the guide member 70a and enters the guide groove 16b of the other guide member 70b.
  Accordingly, the door plate members 10, 20, and 30 are in the open position where the respective end portions are in contact with the left vertical frame 2a in a superposed state, and the opening 1 of the closet is completely opened.
[0086]
  As described above, in the embodiment described with reference to FIGS. 9 to 14, the groove widths of the guide grooves 16 a and 16 e are narrowed toward the back. This configuration is devised so that the frictional force between the pins 7 increases toward the back of the guide grooves 16a and 16e, and is a recommended configuration. However, in the above-described embodiment, the contact force between the pin 7 and the guide grooves 16a and 16e increases with the elastic force of the guide grooves 16a and 16e, so that the groove width of the guide grooves 16a and 16e is not necessarily deep. Even if it is not so narrow as to go to, the frictional force of both increases as it goes to the back side.
[0087]
  In the embodiment described above, the case where there are three door plate members has been described. However, even when there are four or more door plate members, the embodiment can be implemented in the same manner as the above embodiment. Furthermore, the sliding door is not limited to a closet like a closet, and can be used for partitioning various rooms.
[0088]
【The invention's effect】
  According to this invention, since the three or more door plate members move along the rail in relation to each other, the door can be opened and closed basically only by moving one door plate member. Therefore, the sliding door of this invention improves the usability for opening and closing. In addition, when the sliding door of the present invention is used for a closet such as a closet, since the door does not protrude from the opening of the closet, it becomes possible to place furniture such as a bed before the closet, and the layout of the room The effect of being free is demonstrated.
[0089]
  In addition, since separate guide members are provided on both sides of the door plate member in the moving direction, the guide members can be provided regardless of the length of the door plate member in the moving direction. Therefore, even if the width of the door plate member varies depending on the size of the opening, it is possible to use a guide member having a fixed shape, and the guide member can be unitized, and its versatility is enhanced.
[0090]
  Furthermore, since a pair of separate guide members are used, it is not necessary to provide the guide members over the entire length of the rail, and it is possible to reduce the weight of the guide members and reduce material costs.
[0091]
  Further, since the guide member is built in the rail, it is difficult to see from the outside, and there is an effect that the atmosphere of the room is not broken.
[0092]
  And especially claims3In the sliding door described in the above, the position of the locking portion provided in the guide groove is shifted, and another contact portion is provided on the rear side of the locking portion on the side where the locking portion is located on the open side of the guide groove. Since it provided, the sliding door is pushed and moved also by the said contact part. Therefore, the sliding door of the present invention operates smoothly.
[0093]
  And especially claims4Since the guide member is attached to the second door plate member so as to be relatively movable in the moving direction of the door plate member, the guide member and the door plate are opened when the door plate member is expanded and the closet is opened. There is an effect that the positional relationship of the members is deviated and the overlapping portion of the door plate members when the close-up or the like is closed is reduced.
[0094]
  Further claims5In the sliding door described in (1), the width of the guide groove is narrower than the width of the engaging member, and friction is generated between them, so that an appropriate brake is applied to the sliding door and noise is suppressed.
[0095]
  And especially claims6When the engaging member of the first or third door plate member is engaged with the guide groove, a stronger friction is generated between the two at the back side of the groove, and the door plate member is braked. Therefore, in the sliding door of the present invention, even when the door plate members are operated vigorously, when the door plate members are in a predetermined positional relationship, an appropriate brake is applied to the door plate members, and noise is suppressed.
[0096]
  And especially claims7In the sliding door described in the above, the intermediate engagement portion of the guide member is groove-shaped, the pin of the second door plate member is engaged with the groove, and the friction between the pin and the groove is when the pin is at both ends of the groove. Will occur. Therefore, in the sliding door of the present invention, even if the door plate members are operated vigorously, when the door plate members are in a predetermined positional relationship, an appropriate brake is applied to the door plate members, and noise is suppressed.
[0097]
  Especially claims8As shown in the sliding doors described above, on both sides of the guide member, an engaging portion that locks to a locked portion formed on the side surface of the rail is provided, and each guide member includes an engaging portion. When a notch for reducing the width of both engaging portions is formed when locking to the locked portion, for example, each guide is attached to a rail already attached to the frame. There is an advantage that the member can be easily attached and detached with one touch.
[0098]
  Further claims9In the sliding door guide member described in item 1, there is an effect that a plurality of sliding doors can be operated in association with each other and the movement thereof is smooth.
