【発明の属する技術分野】
本発明は、住宅等の部屋に使用される引戸構造であって、詳しくは引戸がガイドレールにより誘導されて、出入り用開口が設けられる壁に対面した開位置と、引戸を出入り用開口と対面した位置で出入り方向と同方向にスライドして出入り用開口を塞ぐ閉位置との間で平行移動可能となっている引戸構造に関するものである。
【0002】
【従来の技術】
一般の引戸1’は、図14に示すように、同一直線上に移動させることで出入り用開口2の開閉を行なっており、この種の引戸1’は遮音性、密閉性が低下するという問題があり、しかも引戸1’に反りが発生すると、引戸1’と壁4とが擦れて、スムーズに開閉できなくなるという問題もある。
【0003】
そこで、従来、例えば図15に示すように、家具門口52(出入り用開口)に沿って斜前方に延びるように固定された第一レール50(固定レール)に、平面視櫛形をした第二レール51(可動レール)を摺動自在にガイドすると共に、第二レール51に対して引戸1”を取り付け、引戸1”を開くと、図15(b)のように第二レール51が第一レール50の前端部に移動して、引戸1”は壁4と対面する位置まで移動し、引戸1”を閉じると、図15(a)のように第二レール51が第一レール50の後端部に移動して、引戸1”が斜めに移動して家具門口52を塞ぐ位置まで移動するものが開示されている。(例えば、特許文献1参照)。
【0004】
また、他の従来例として、レール上を移動する第1の車輪と第2の車輪とをそれらの軸線の向きが直交する関係になるように走行台に軸支し、スライディングドアの走行方向を直角方向に変換させる吊車装置が開示されている(例えば、特許文献2参照。)。
【0005】
【特許文献1】
特開昭61−113981号公報(第1図、第2図)
【特許文献2】
特開昭57−127083号公報(第1図、第2図)
【0006】
【発明が解決しようとする課題】
ところで、上記特許文献1に開示されているものでは、引戸1”を開いた状態では第二レール51が家具門口52の前方に露出して突出するために、外観が悪くなるという問題があり、しかも第二レール51(可動レール)を第一レール50(固定レール)に対して斜めに移動させる機構となるため、レールの構造が複雑化するという問題もある。
【0007】
なお、上記特許文献2には引戸を壁に対面した開位置と、閉位置直前で出入り方向と同方向にスライドして出入り用開口を塞ぐ閉位置との間で平行移動させる構造についての開示はない。
【0008】
本発明は、上記の従来例の問題点に鑑みて発明したものであって、その目的とするところは、引戸の開位置では外観が良く、閉位置では出入り用開口を確実に塞ぐことができて高い防音性、気密性を確保できるものでありながら、引戸が出入り方向と同方向にスライドするときにガイドレールと吊り部材との間で突っかかりや、がたつきが生じるのを防止でき、スムーズに開閉操作できるようにした引戸構造を提供することにあり、他の目的とするところは、引戸の横ブレを防止できる引戸構造を提供することにあり、更に他の目的とするところは、下レールを備えたものでありながら、床面のバリアフリー化に対応できる引戸構造を提供することにある。
【0009】
【課題を解決するための手段】
上記課題を解決するために本発明にあっては、引戸1がガイドレール2により誘導されて、出入り用開口3が設けられる壁4に対面した開位置と、引戸1を出入り用開口3と対面した位置で出入り方向Cと同方向にスライドして出入り用開口3を塞ぐ閉位置との間で平行移動可能となっている引戸構造であって、上記ガイドレール2は、出入り方向Cに対して直角方向Dに延設されてその長さ方向の略半分が壁4と対面し且つ残りの略半分が出入り用開口3と対面する位置に設置される直線状レール2Aと、引戸1を出入り用開口3と対面した位置で出入り方向Cと同方向にスライドさせるための傾斜部10を有する傾斜状レール2Bとで構成され、引戸1の上端部1aを吊り下げる吊り部材5は、直線状レール2Aにガイドされて出入り方向Cに対して直角方向Dのみに直進する第1の直進用ローラー部材6と、第1の直進用ローラー部材6に支持され且つ傾斜状レール2Bにガイドされて出入り方向Cと同方向のみに直進する第2の直進用ローラー部材7とで構成されると共に、第2の直進用ローラー部材7に引戸1の上端部1aを吊り下げる引戸吊持手段9が設けられ、天板24と側板25とからなる上レールカバー22の下面の開口に下カバー23が装着され、上記第1の直進用ローラー部材6と上記第2の直進用ローラー部材7からなる吊り部材5が上レールカバー22と下カバー23との間に配置され、上レールカバー22内に第1の直進用ローラー部材6をガイドする上記直線状レール2Aが設けられ、下カバー23に溝を穿設することで上記傾斜状レール2Bが形成されたことを特徴としており、このように構成することで、引戸1の吊り部材5は閉位置直前で傾斜状レール2Bに沿って傾斜して移動するが、この傾斜した移動軌跡Fのうち垂直移動成分Fを第1の直進用ローラー部材6が受け持ち、水平移動成分Fを第2の直進用ローラー部材7が受け持つことによって、傾斜移動を直進移動に変換でき、傾斜状レール2Bに対する吊り部材5の追随性が良くなる。従って、ガイドレール2と吊り部材5との間で突っかかりや、がたつきが生じるのを防止できるようになり、引戸1をスムーズに開閉できるようになる。
【0010】
また上記傾斜状レール2Bの傾斜部10は、平面視で円弧状に湾曲形成されているのが好ましく、この場合、吊り部材5の移動軌跡Fが傾斜部10に沿って緩やかな円弧を描くようになり、これにより引戸1をよりスムーズに開閉できるものである。
【0011】
また上記壁4の下端部に下レール11を設けると共に、下レール11にガイドされる下ガイド部材12を引戸1の下端部1bに下ガイド部材12の長孔42aを介して上下に高さ調整自在にネジ42bにて取り付けるのが好ましく、この場合、床面に下レール11を設置する必要がなくなり、床面のバリアフリー化に対応できると共に、下ガイド部材12によって引戸1の下端部1bの横ブレを防止でき、よりスムーズな開閉動作ができるようになる。また下ガイド部材12の高さ位置を簡単に調整できる。
【0012】
また上記下レール11を壁4の下端部に設置される巾木13に一体形成するのが好ましく、この場合、ゴミや埃が下レール11内に溜まりにくく、掃除もしやすくなり、また下レール11の存在が目立たず、デザイン性が向上する。
【0013】
また上記床面14に傾斜状レール2Bと追随する形状をした床直付けガイドレール15を設置すると共に、床直付けガイドレール15ガイドされる下ランナー16を引戸1の下端部1bに取り付けるのが好ましく、この場合、床直付けガイドレール15にガイドされて下ランナー16が引戸1の上端部1aに設けた吊り部材5と同じ移動軌跡をたどることとなり、引戸1の横ブレ防止を一層図ることができる。
【0014】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【0015】
図1は、本実施形態のガイドレール2を構成する直線状レール2A及び傾斜状レール2B,2Bを説明する平面断面図、図2は引戸1の開閉状態を説明する概略平面図、図3乃至図5は吊り部材5の説明図である。
【0016】
引戸1はガイドレール2により誘導されて、図2に示すように、壁4(袖壁)に対面した開位置と、出入り用開口3と対面した位置(以下、閉位置直前という。)で出入り方向Cと同方向にスライドして出入り用開口3を塞ぐ閉位置との間で平行移動可能となっている。
【0017】
ここで、引戸枠18は、例えば図6に示すように、上枠19と戸先側の縦枠20と戸尻側の縦枠20と中央の中方立21とで構成されており、戸先側の縦枠20と中方立21との間が引戸1にて開閉される出入り用開口3となっており、戸先側の縦枠20と中方立21との間は戸袋部26となっている。なお、戸尻側の縦枠20は省略可能である。
【0018】
引戸1の上端部1aの前後2箇所にはそれぞれ吊り部材5が設けられ、引戸枠18の上枠19にガイドレール2が設置されている。
【0019】
ガイドレール2は、図1に示すように、1つの長尺の直線状レール2Aと、前後2つの短尺の傾斜状レール2Bとで構成されている。
【0020】
ここでは、図4に示すように、直線状レール2Aは下面が開口した断面箱形状の上レールカバー22に設けられ、傾斜状レール2Bは上レールカバー22の下面開口に装着される下カバー23に設けられている。
【0021】
上レールカバー22は、図4に示すように、天板24と左右の側板25とからなり、左右の側板25の内面には、左右一対の略U形レール片からなる直線状レール2Aが突設されている。上レールカバー22はその巾方向Eの略半分が上壁4aと上枠19とのなす上部凹所27内に収納され、天板24の中央部から上方に突出した立上り片28が上壁4aの側面にネジ固定され、天板24の一端から横方向に突出した横片29が上壁4aの下面にネジ固定されている。ここでは、天板24の横片29は上枠19の上面に設けた切欠き80内に挿入され、これにより、上レールカバー22の一方の側板25を上枠19の側面に密着させた状態で上レールカバー22を上壁4aに対して固定できるようになっている。
【0022】
また、上レールカバー22は、図1に示すように、引戸枠18の戸先側の縦枠20と戸尻側の縦枠20との間の全長に亘って延設され、その長さ方向の略半分が中方立21と戸尻側の縦枠20との間の壁4と対面する位置に位置し、残りの略半分が出入り用開口3と対面する位置に設置される。これにより、直線状レール2Aは出入り方向Cに対して直角方向Dに延設された状態で、その長さ方向の略半分が壁4と対面し且つ残りの略半分が出入り用開口3と対面するようになっている。また、上レールカバー22はその巾方向Eの内端側が出入り用開口3の内側に入り込んでいる。図1中の22は化粧額縁である。
【0023】
さらに、上レールカバー22の下面開口には下方から下カバー23が嵌め込まれ、上レールカバー22の下面開口の左右両側面に設けた一対の係止突起30に対して下カバー23の両端部に設けた係止爪31がそれぞれ係止することで、上レールカバー22に対して下カバー23を下方から係止可能となっている。下カバー23には、引戸1を閉位置直前で出入り方向Cと同方向にスライドさせるための傾斜部10を有する傾斜状レール2Bが設けられている。本例では図5に示すように、下カバー23の中央部分を上下にくりぬいて、直線状レール2Aと略平行に延びた延出部17と、延出部17に連らなり出入り用開口3に向かって傾斜した傾斜部10とが形成されている。ここでは、傾斜部10は、平面視で円弧状に湾曲形成されている。また引戸1の前後2箇所に設けた吊り部材5,5に個別に対応して、下カバー23の前後2箇所に傾斜状レール2B,2Bが形成されている。
【0024】
一方、引戸1の吊り部材5は、直線状レール2Aにガイドされて出入り方向Cに対して直角方向Dのみに直進する第1の直進用ローラー部材6と、第1の直進用ローラー部材6に支持され且つ傾斜状レール2Bにガイドされて出入り方向Cと同方向のみに直進する第2の直進用ローラー部材7とで構成されている。
【0025】
第1の直進用ローラー部材6は、図3、図4に示すように、台車32の四隅に設けたローラー取付金具33にローラー45が各々取り付けられており、これら各ローラー45が直線状レール2A上を転動することで第1の直進用ローラー部材6は直線状レール2Aと同方向(出入り方向Cに対して直角方向)のみに直進移動するようになっている。この第1の直進用ローラー部材6上には、図4、図5に示すように、第1の直進用ローラー部材6の移動方向に対して直角方向Dのみに直進可能な第2の直進用ローラー部材7が搭載されている。第2の直進用ローラー部材7は第1の直進用ローラー部材6よりも小型であり、その四隅にローラー46がそれぞれ回転自在に取り付けられている。
【0026】
第1の直進用ローラー部材6の台車32の中央部には、第1の直進用ローラー部材6の移動方向に対して直角方向D(出入り方向Cと同方向)に向かって直線上に延びた長孔状のガイド孔35が貫通形成されており、ガイド孔35の両側方に第2の直進用ローラー部材7の各ローラー46が配置される。第2の直進用ローラー部材7の中央下面から下方に突出したガイド手段8を構成するガイド軸8aがガイド孔35にスライド自在に挿通され、さらにガイド軸8aは下カバー23に設けた傾斜状レール2Bにスライド自在に挿通されている。なおガイド軸8aの平面断面形状は円形に限らず、四角形であってもよい。
【0027】
ここで、引戸1は閉位置直前で傾斜状レール2Bに沿って傾斜した移動軌跡Fとなるが、このとき吊り部材5の移動軌跡Fは第1の直進用ローラー部材6と第2の直進用ローラー部材7とによって、垂直移動成分Fと水平移動成分Fとに振り分けられて、後述のように傾斜移動を直進移動に変換できる構造となっている。なお、第2の直進用ローラー部材7の上面には複数の浮き上がり防止用凸部44が上方に突設されており、この浮き上がり防止用凸部44の上端部が上レールカバー22の天板24下面に摺接することで、第2の直進用ローラー部材7の浮き上がりを防止でき、ひいては吊り部材5全体の浮き上がりを防止でき、引戸1の上下のがたつきを防止できるようになっている。
【0028】
さらに第2の直進用ローラー部材7のガイド軸8aは、引戸1の上端部1aを吊り下げる引戸吊持手段9を兼用している。ここでは、ガイド軸8aの下端部を引戸1の上端部1aに対して第2の直進用ローラー部材7の高さを調整するための調整機構36に連結している。なおガイド軸8aとは別に引戸吊持軸を設けてもよい。
【0029】
しかして、引戸1の閉位置直前で吊り部材5は傾斜状レール2Bにより傾斜した移動軌跡F(図5)をとる。この傾斜した移動軌跡Fのうち垂直移動成分Fを第1の直進用ローラー部材6が受け持ち、水平移動成分Fを第2の直進用ローラー部材7が受け持つ。つまり、引戸1を吊り下げている第2の直進用ローラー部材7のガイド軸8aが図5に示すガイド孔35の一端P側→中央側P→他端P側に移動する。これにより、第2の直進用ローラー部材7は図5の矢印Cで示す方向(出入り方向Cと同方向)のみに直進移動する。このとき、第1の直進用ローラー部材6は図5の矢印Dで示す方向(直線状レール2Aの戸当たり側)に向かって直進移動する。なお、引戸1を開くときはこれとは逆の動作となる。
【0030】
このように、吊り部材5全体の傾斜移動を2つの直進用ローラー部材6,7による直進移動に変換することで、傾斜状レール2Bに対する吊り部材5の追随性が良くなり、従って、ガイドレール2と吊り部材5との間で突っかかりや、がたつきが生じるのを防止できるようになり、引戸1をスムーズに開閉できるようになる。特に閉位置から開くときの初動操作力を軽減できるので、引戸1の開閉操作性が大幅に向上するものである。しかも浮き上がり防止用凸部によって引戸1の浮き上がりを防止しているので、引戸1の上下方向のがたつきも同時に防止できるものである。
【0031】
また、引戸1の開位置では従来のように可動レールが突出して外観が損なわれるようなこともないので、見栄えが良くなる。また引戸1の閉位置では、出入り方向Cと同方向にスライドして出入り用開口3に入り込んだ状態で出入り用開口3を確実に塞ぐようになるので、高い防音性、気密性を確保でき、音漏れや明かり漏れ、隙間風等の課題を解決できると共に、引戸1が出入り用開口3に入り込んでフラットに納まることで引戸1と壁4との一体感が得られる。そのうえ、直線状レール2Aと傾斜状レール2Bとを上レールカバー22と下カバー23とに一体に設けており、ガイドレール2の構成が簡易となり、しかもガイド軸8aが引戸吊持手段9を兼用しているので、吊り部材5の部品数を削減でき、施工性が良くなるという利点もある。
【0032】
次に、引戸1の下端部1bをガイドする機構について説明する。なお、引戸1の上端部1aの吊り部材5及びガイドレール2については前記実施形態と同様であり、説明は省略する。本例では壁4の戸袋部4bの下端部に、図6、図7に示すように、傾斜状レール2B(図1)と追随する形状をした下レール11が設けられている。本例の下レール11は、図8に示すように、壁4の下端部に設置された巾木13に一体形成されている。この壁4の巾木13は、戸尻側の縦枠20を挟んで、壁4の巾木13b(図6)に連続した外観を呈している。ここで、壁4の巾木13は、断面コ字状の巾木本体13aの上部に断面逆コ字状の下レール11が一体化されたものであり、下レール11は、傾斜状レール2Bと同様、出入り用開口3側に向かって円弧状に湾曲した傾斜部10’を有している。なお、本例では下レール11の上に巾木本体13aを一体に連設しているが、巾木本体13aを省略して下レール11のみで巾木を形成することも可能である。ここでは図8に示すように、壁4の中方立21側の下端部に平面視略台形状の凹部38を切欠き形成し、この凹部38内に下レール11の傾斜部10’を挿入してある。この下レール11には、図9に示すように、引戸1の戸当り側とは反対側の側端面の下端部に取り付けた下ガイド部材12がスライド自在に挿入されている。下ガイド部材12は、ガイドローラー40と、ガイドローラー40を引戸1に取り付けるガイドローラー取付具41とからなる。ガイドローラー取付具41は、図10に示すように、引戸1の側端面に対してL字片42がネジ固定され、このL字片42から水平に突出する延出片43の先端に縦軸回りに回転自在にガイドローラー40を取り付け、このガイドローラー40を下レール11内に走行自在に挿入している。なおガイドローラー40の高さ調整はL字片42の長孔42aをネジ42bに沿って上下させることで行なうことができる。
【0033】
しかして、巾木13に下レール11を一体に設けたので、床面14に下レール11を設置する必要がなくなり、床面14のバリアフリー化に対応できると共に、ゴミや埃が下レール11内に溜まりにくく、掃除もしやすくなり、また床面14の不陸にも対応できる上に、下レール11の存在が目立たないものであり、まそのうえ下レール11の傾斜部10’を挿入する下隅凹所38は壁4の下端部の隅部に設けているので、下隅凹所38が目立ちにくく、引戸1を閉じたときに壁4や巾木13の外観を損なうことがないものであり、結果、デザイン性が向上するという利点がある。また、下ガイド部材12によって引戸1の下端部1bの横ブレを防止できるので、よりスムーズな開閉動作が可能となる。また本例では下レール11は傾斜状レール2Bと追随する形状をしているので、閉位置直前でガイドローラー40は出入り方向Cと同方向にスライドすることができ、しかもガイドローラー40は縦軸回りに回転できるので、下レール11の傾斜部10’に対する追随性が良くなり、これにより、引戸1の横ブレ防止に効果的となる。しかもガイドローラー40は、ガイドローラー取付具41によって引戸1から所定の距離Hをあけて保持されているため、図8に示すように、ガイドローラー40が下レール11の傾斜部10’に入り込んだときでも、引戸1の下端部1bがガイドローラー40に引っ張られて傾くようなことがなく、これにより引戸1によって出入り用開口3を確実に密閉することができる。また下ガイド部材12を引戸1の下端部1bの1箇所に設けることで、構造を簡易化できるという利点もある。
【0034】
図11〜図13は引戸1の下端部1bをガイドする機構の他例として、床面14に、傾斜状レール2B(図1)と追随する形状をした床直付けガイドレール15を設置すると共に、引戸1の下端部1bに縦軸回りに回転自在に取り付けた下ランナー16を床直付けガイドレール15に走行自在に支持したものである。なお、他の構成は図1と同様であり、異なる点だけを述べる。本例の床直付けガイドレール15は断面半円形状に形成され、床面14上に設置されている。この床直付けガイドレール15は、図1の傾斜状レール2Bの真下に配置されており、傾斜状レール2Bと同様、出入り用開口3側に向かって円弧状に湾曲した傾斜部10”を有している。引戸1の下端部1bには図12、図13に示すように、床直付けガイドレール15にガイドされる下ランナー16が取り付けられている。ここでは、下ランナー16として、図12(b)の縦軸Mを中心に矢印イで示す水平回りに回転自在なキャスター16a(回転戸車)が用いられる。
【0035】
しかして、床直付けガイドレール15を傾斜状レール2Bと追随する形状としたので、床直付けガイドレール15にガイドされて下ランナー16は閉位置直前で出入り方向Cと同方向にスライドすることができ、引戸1の横ブレ防止を図ることができる。また、キャスター16aは図12(b)のように縦軸回りに回転できるので、床直付けガイドレール15に対するキャスター16aの追随性が良くなり、これによりキャスター16aと床直付けガイドレール15との間でのがたつきを一層防止でき、その結果、引戸1の開閉操作性が一層向上するものである。なお下ランナー16としてキャスター16aには限定されず、例えばバネ付き凸状ガイドを引戸1の下端部1bから突出させ、床直付けガイドレール15にバネ付き凸状ガイド(図示せず)をガイドする凹溝を設けたものであってもよい。また、引戸1の戸当たり側Gと反対側の下端部のみに下ランナー16を設け、出入り用開口3を避けて床直付けガイドレール15を設置することが望ましく、この場合、出入り用開口3の床面14をバリアフリー化することが可能となる。もちろん、引戸1の下端部1bの2箇所に下ランナー16を取り付けると共に、出入り用開口3の床面14に床直付けガイドレール15を設置してもよいものである。
【0036】
本発明の引戸構造は、手動引戸のみならず電動引戸の分野にも広く適用可能である。

FIG. 5 is an explanatory diagram of the suspension member 5.
[0016]
The sliding door 1 is guided by the guide rail 2 and, as shown in FIG. 2, enters and exits at an open position facing the wall 4 (sleeve wall) and a position facing the entrance / exit opening 3 (hereinafter referred to as just before the closed position). It can be moved in parallel with the closed position that slides in the same direction as the direction C and closes the entrance / exit opening 3.
[0017]
Here, for example, as shown in FIG. 6, the sliding door frame 18 includes an upper frame 19, a door-side vertical frame 20, a door-side vertical frame 20, and a central neutral 21. Between the vertical frame 20 on the side and the neutral stand 21 is an entrance / exit opening 3 that is opened and closed by the sliding door 1, and between the vertical frame 20 on the door side and the neutral stand 21 is a door pocket portion 26. Yes. Note that the vertical frame 20 on the door bottom side can be omitted.
[0018]
Suspension members 5 are provided at two positions on the front and rear of the upper end portion 1a of the sliding door 1, and the guide rail 2 is installed on the upper frame 19 of the sliding door frame 18.
[0019]
As shown in FIG. 1, the guide rail 2 is composed of one long linear rail 2 </ b> A and two short front and rear inclined rails 2 </ b> B.
[0020]
Here, as shown in FIG. 4, the linear rail 2 </ b> A is provided on the upper rail cover 22 having a cross-sectional box shape with the lower surface opened, and the inclined rail 2 </ b> B is mounted on the lower surface opening of the upper rail cover 22. Is provided.
[0021]
As shown in FIG. 4, the upper rail cover 22 includes a top plate 24 and left and right side plates 25, and linear rails 2 </ b> A including a pair of left and right substantially U-shaped rail pieces project on the inner surfaces of the left and right side plates 25. It is installed. About half of the upper rail cover 22 in the width direction E is housed in an upper recess 27 formed by the upper wall 4a and the upper frame 19, and a rising piece 28 protruding upward from the center of the top plate 24 has an upper wall 4a. A lateral piece 29 that is fixed to the side surface of the top plate 24 and protrudes laterally from one end of the top plate 24 is fixed to the lower surface of the upper wall 4a. Here, the horizontal piece 29 of the top plate 24 is inserted into a notch 80 provided on the upper surface of the upper frame 19, whereby one side plate 25 of the upper rail cover 22 is in close contact with the side surface of the upper frame 19. Thus, the upper rail cover 22 can be fixed to the upper wall 4a.
[0022]
Moreover, the upper rail cover 22 is extended over the full length between the vertical frame 20 of the door-end side of the sliding door frame 18, and the vertical frame 20 of the door butt side, as shown in FIG. Is located at a position facing the wall 4 between the neutral 21 and the vertical frame 20 on the door butt side, and the other half is disposed at a position facing the entrance / exit opening 3. Thereby, in a state where the linear rail 2A is extended in the direction D perpendicular to the entrance / exit direction C, approximately half of the length direction faces the wall 4 and the remaining approximately half faces the entrance / exit opening 3. It is supposed to be. Further, the upper rail cover 22 has its inner end side in the width direction E entering the inside of the entrance / exit opening 3. In FIG. 1, 22 is a makeup frame.
[0023]
Further, a lower cover 23 is fitted into the lower surface opening of the upper rail cover 22 from below, and at both ends of the lower cover 23 with respect to a pair of locking protrusions 30 provided on the left and right side surfaces of the lower surface opening of the upper rail cover 22. Since the provided locking claws 31 are respectively locked, the lower cover 23 can be locked to the upper rail cover 22 from below. The lower cover 23 is provided with an inclined rail 2B having an inclined portion 10 for sliding the sliding door 1 in the same direction as the entrance / exit direction C immediately before the closing position. In this example, as shown in FIG. 5, the center portion of the lower cover 23 is hollowed up and down to extend an extension portion 17 extending substantially parallel to the linear rail 2 </ b> A, and to the extension opening 17. And an inclined portion 10 inclined toward the surface. Here, the inclined portion 10 is curved in an arc shape in plan view. Further, inclined rails 2 </ b> B and 2 </ b> B are formed at two front and rear portions of the lower cover 23, corresponding to the suspension members 5 and 5 provided at two front and rear portions of the sliding door 1.
[0024]
On the other hand, the suspension member 5 of the sliding door 1 is guided by the linear rail 2 </ b> A so as to move straight in only the direction D perpendicular to the direction of entry / exit C, and the first straight movement roller member 6. The second linearly moving roller member 7 is supported and guided by the inclined rail 2 </ b> B and travels straight only in the same direction as the exit / entry direction C.
[0025]
As shown in FIGS. 3 and 4, the first straight roller member 6 has rollers 45 attached to roller mounting brackets 33 provided at the four corners of the carriage 32, and these rollers 45 are linear rails 2 </ b> A. By rolling upward, the first linearly moving roller member 6 moves linearly only in the same direction as the linear rail 2A (perpendicular to the exit / entry direction C). As shown in FIGS. 4 and 5, on the first linear roller member 6, as shown in FIG. 4 and FIG. 5, the second linearly movable member that can linearly travel only in the direction D perpendicular to the moving direction of the first linear roller member 6. A roller member 7 is mounted. The second rectilinear roller member 7 is smaller than the first rectilinear roller member 6, and rollers 46 are rotatably attached to the four corners thereof.
[0026]
In the central portion of the carriage 32 of the first linearly moving roller member 6, a straight line extends in a direction D perpendicular to the moving direction of the first linearly moving roller member 6 (the same direction as the entrance / exit direction C). A long hole-shaped guide hole 35 is formed so as to penetrate therethrough, and the rollers 46 of the second linearly moving roller member 7 are disposed on both sides of the guide hole 35. A guide shaft 8a constituting guide means 8 projecting downward from the central lower surface of the second linearly moving roller member 7 is slidably inserted into the guide hole 35, and the guide shaft 8a is an inclined rail provided on the lower cover 23. 2B is slidably inserted. The planar cross-sectional shape of the guide shaft 8a is not limited to a circle but may be a rectangle.
[0027]
Here, the sliding door 1 becomes a movement locus F inclined along the inclined rail 2B immediately before the closing position. At this time, the movement locus F of the suspension member 5 is the first straight movement roller member 6 and the second straight movement direction. By the roller member 7, the vertical movement component F2And horizontal movement component F1As described later, the tilt movement can be converted into the straight movement. A plurality of lifting prevention convex portions 44 project upward from the upper surface of the second linearly moving roller member 7, and the upper end portion of the lifting prevention convex portion 44 is the top plate 24 of the upper rail cover 22. By sliding in contact with the lower surface, it is possible to prevent the second linearly moving roller member 7 from being lifted, and thus to prevent the entire suspension member 5 from being lifted, and to prevent the sliding door 1 from shaking up and down.
[0028]
Further, the guide shaft 8 a of the second linearly moving roller member 7 also serves as the sliding door suspension means 9 that suspends the upper end portion 1 a of the sliding door 1. Here, the lower end portion of the guide shaft 8 a is connected to the adjustment mechanism 36 for adjusting the height of the second linearly moving roller member 7 with respect to the upper end portion 1 a of the sliding door 1. In addition to the guide shaft 8a, a sliding door suspension shaft may be provided.
[0029]
Therefore, immediately before the closing position of the sliding door 1, the suspension member 5 takes a movement locus F (FIG. 5) inclined by the inclined rail 2 </ b> B. Of this inclined movement locus F, the vertical movement component F2The first linearly moving roller member 6 takes charge of the horizontal movement component F1Is handled by the second linearly moving roller member 7. That is, the guide shaft 8a of the second linearly moving roller member 7 suspending the sliding door 1 is one end P of the guide hole 35 shown in FIG.1Side → center side P2→ other end P3Move to the side. As a result, the second linearly moving roller member 7 is moved toward the arrow C in FIG.1It moves straight ahead only in the direction indicated by (the same direction as the entrance / exit direction C). At this time, the first straight-traveling roller member 6 is an arrow D in FIG.1It moves straight toward the direction indicated by (the door stop side of the linear rail 2A). In addition, when opening the sliding door 1, it becomes an operation | movement contrary to this.
[0030]
Thus, by converting the inclination movement of the whole suspension member 5 into the straight movement by the two linear advance roller members 6 and 7, the followability of the suspension member 5 with respect to the inclined rail 2B is improved. It becomes possible to prevent bumping and rattling between the suspension member 5 and the suspension member 5, and the sliding door 1 can be opened and closed smoothly. In particular, since the initial operation force when opening from the closed position can be reduced, the opening / closing operability of the sliding door 1 is greatly improved. Moreover, since the lifting of the sliding door 1 is prevented by the lifting prevention convex portion, the vertical shaking of the sliding door 1 can be prevented at the same time.
[0031]
Further, since the movable rail does not protrude and the appearance is not impaired as in the conventional case at the open position of the sliding door 1, the appearance is improved. In addition, in the closed position of the sliding door 1, it slides in the same direction as the entrance / exit direction C so as to reliably close the entrance / exit opening 3 while entering the entrance / exit opening 3, thereby ensuring high soundproofing and airtightness, While solving problems such as sound leaks, light leaks, and drafts, the sliding door 1 enters the entrance / exit opening 3 and fits flatly, thereby providing a sense of unity between the sliding door 1 and the wall 4. In addition, the linear rail 2A and the inclined rail 2B are integrally provided on the upper rail cover 22 and the lower cover 23, the structure of the guide rail 2 is simplified, and the guide shaft 8a also serves as the sliding door suspension means 9. Therefore, there is an advantage that the number of parts of the suspension member 5 can be reduced and workability is improved.
[0032]
Next, a mechanism for guiding the lower end 1b of the sliding door 1 will be described. In addition, about the suspension member 5 and the guide rail 2 of the upper end part 1a of the sliding door 1, it is the same as that of the said embodiment, and description is abbreviate | omitted. In this example, a lower rail 11 having a shape following the inclined rail 2B (FIG. 1) is provided at the lower end portion of the door pocket portion 4b of the wall 4 as shown in FIGS. As shown in FIG. 8, the lower rail 11 in this example is integrally formed with a baseboard 13 installed at the lower end of the wall 4. The skirting board 13 of the wall 4 has a continuous appearance with the skirting board 13b (FIG. 6) of the wall 4 with the vertical frame 20 on the door bottom side in between. Here, the baseboard 13 of the wall 4 is obtained by integrating a lower rail 11 having an inverted U-shaped cross section on an upper portion of a baseboard body 13a having a U-shaped cross section, and the lower rail 11 is an inclined rail 2B. In the same manner, the inclined portion 10 ′ is curved in an arc shape toward the entrance / exit opening 3 side. In this example, the baseboard body 13a is integrally provided on the lower rail 11. However, it is also possible to omit the baseboard body 13a and form the baseboard with only the lower rail 11. Here, as shown in FIG. 8, a substantially trapezoidal concave portion 38 in a plan view is cut out at the lower end portion of the wall 4 on the neutral 21 side, and the inclined portion 10 ′ of the lower rail 11 is inserted into the concave portion 38. It is. As shown in FIG. 9, a lower guide member 12 attached to the lower end portion of the side end surface of the sliding door 1 opposite to the door contact side is slidably inserted into the lower rail 11. The lower guide member 12 includes a guide roller 40 and a guide roller attachment 41 that attaches the guide roller 40 to the sliding door 1. As shown in FIG. 10, the guide roller fixture 41 has an L-shaped piece 42 screwed to the side end surface of the sliding door 1, and a vertical axis at the tip of an extending piece 43 protruding horizontally from the L-shaped piece 42. A guide roller 40 is attached so as to be rotatable around, and the guide roller 40 is inserted into the lower rail 11 so as to run freely. The height of the guide roller 40 can be adjusted by moving the elongated hole 42a of the L-shaped piece 42 up and down along the screw 42b.
[0033]
Thus, since the lower rail 11 is integrally provided on the baseboard 13, it is not necessary to install the lower rail 11 on the floor surface 14, and the floor surface 14 can be made barrier-free. It is difficult to collect in the interior, it is easy to clean, and it can cope with the uneven surface of the floor 14 and the presence of the lower rail 11 is inconspicuous. Moreover, the lower corner into which the inclined portion 10 'of the lower rail 11 is inserted Since the recess 38 is provided at the corner of the lower end of the wall 4, the lower corner recess 38 is not conspicuous, and does not impair the appearance of the wall 4 or the baseboard 13 when the sliding door 1 is closed. As a result, there is an advantage that the design is improved. In addition, since the lower guide member 12 can prevent lateral blurring of the lower end 1b of the sliding door 1, a smoother opening and closing operation is possible. Further, in this example, since the lower rail 11 has a shape that follows the inclined rail 2B, the guide roller 40 can slide in the same direction as the entrance / exit direction C immediately before the closed position, and the guide roller 40 has a vertical axis. Since it can rotate around, the followability with respect to the inclined portion 10 ′ of the lower rail 11 is improved, and this is effective in preventing lateral shaking of the sliding door 1. Moreover, since the guide roller 40 is held at a predetermined distance H from the sliding door 1 by the guide roller attachment 41, the guide roller 40 has entered the inclined portion 10 ′ of the lower rail 11 as shown in FIG. Even at times, the lower end portion 1b of the sliding door 1 is not pulled and tilted by the guide roller 40, so that the entrance / exit 3 can be reliably sealed by the sliding door 1. Further, by providing the lower guide member 12 at one place on the lower end 1b of the sliding door 1, there is an advantage that the structure can be simplified.
[0034]
FIGS. 11 to 13 show another example of a mechanism for guiding the lower end portion 1b of the sliding door 1, in which a floor directly attached guide rail 15 having a shape following the inclined rail 2B (FIG. 1) is installed on the floor surface 14. The lower runner 16 attached to the lower end portion 1b of the sliding door 1 so as to be rotatable about the vertical axis is supported on the guide rail 15 on the floor so that it can run freely. Other configurations are the same as those in FIG. 1, and only different points will be described. The floor direct mounting guide rail 15 of this example is formed in a semicircular cross section and is installed on the floor surface 14. This floor direct mounting guide rail 15 is disposed directly below the inclined rail 2B of FIG. 1, and has an inclined portion 10 ″ that is curved in an arc toward the entrance / exit opening 3 as in the inclined rail 2B. 12 and 13, a lower runner 16 guided by a floor direct mounting guide rail 15 is attached to the lower end 1b of the sliding door 1. Here, as the lower runner 16, A caster 16a (rotary door wheel) is used which is rotatable about a vertical axis M in FIG.
[0035]
Since the floor direct mounting guide rail 15 has a shape that follows the inclined rail 2B, the lower runner 16 is guided by the floor direct mounting guide rail 15 and slides in the same direction as the access direction C just before the closing position. It is possible to prevent lateral sliding of the sliding door 1. Further, since the caster 16a can be rotated around the vertical axis as shown in FIG. 12B, the follower of the caster 16a with respect to the floor direct attachment guide rail 15 is improved, and thereby, the caster 16a and the floor direct attachment guide rail 15 are separated. The backlash between the sliding doors 1 can be further prevented, and as a result, the opening / closing operability of the sliding door 1 is further improved. The lower runner 16 is not limited to the caster 16a. For example, a spring-loaded convex guide protrudes from the lower end 1b of the sliding door 1, and the floor-mounted guide rail 15 guides the spring-loaded convex guide (not shown). A groove may be provided. Further, it is desirable that the lower runner 16 is provided only at the lower end of the sliding door 1 opposite to the door contact side G, and the floor directing guide rail 15 is installed avoiding the entrance / exit opening 3. In this case, the entrance / exit opening 3 The floor surface 14 can be made barrier-free. Of course, the lower runner 16 may be attached to two places on the lower end portion 1b of the sliding door 1 and the floor direct attachment guide rail 15 may be installed on the floor surface 14 of the access opening 3.

Become.Further, the height position of the lower guide member can be easily adjusted.
[0040]
Moreover, in addition to the effect of Claim 3, since the lower rail was integrally formed with the baseboard installed in the lower end part of a wall, the invention of Claim 4 was made into a garbage or a garbage by incorporating a lower rail in a baseboard. Dust is less likely to collect in the lower rail, making it easier to clean, and the presence of the lower rail is inconspicuous, improving design.
[0041]
In addition to the effect of the first or second aspect, the invention according to claim 5 is provided with a floor direct mounting guide rail having a shape that follows the inclined rail on the floor surface, and the floor direct mounting guide rail. The lower runner guided by the sliding door is attached to the lower end of the sliding door, so that the lower runner slides in the same direction as the entrance / exit just before being closed by the guide rail mounted directly on the floor. Smoother opening / closing operation is possible.
