Description

【０００１】
【発明の属する技術分野】
この発明は、複数個の戸パネルで構成した引き戸において、一側端の戸パネルを開閉することにより、他の戸パネルも同時に連動開閉できる連動引き戸に関する。
【０００２】
【従来の技術】
ピニオンとラックを機構要素とする連動引き戸は、特公昭５７−５２４７３号公報に公知である。特公昭５８−３３３５４号公報には、ベルトやチェーン等の無端帯を機構要素とする連動引き戸が開示されている。そこでは、前後に重なる３個の戸パネルで引き戸を構成し、中間の戸パネルの上端面の両側にスプロケットギヤを配置し、両ギヤにチェーンを巻き掛け装着している。前後の各戸パネルは、それぞれチェーンの直線移行部に同行可能に連結してあり、一側端の戸パネルを開閉操作すると、他の戸パネルを同時に連動開閉できる。
【０００３】
【発明が解決しようとする課題】
無端帯を機構要素とする上記の引き戸は、前後の各戸パネルを無端帯の直線移行部の端々に連結固定するので、前後の各戸パネルは、無端帯の前部あるいは後部の直線移行部の両端間を往復移動できるに過ぎない。そのため、例えば前側の戸パネルを開き始端とするとき、引き戸の開き方向が右勝手と左勝手のいずれかに特定される。詳しくは、前側の戸パネルが中間の戸パネルの右前に位置し、後側の戸パネルが中間の戸パネルの左後に位置して、引き戸の全体が戸枠の開口面を閉じている場合には、前側の戸パネルを開き始端とすると、引き戸は左開き型としてしか使用できない。
【０００４】
こうした制約は、前側の戸パネルと後側の戸パネルのいずれか一方を開き始端とすることで解消できる。しかし、引き戸を全開した状態では、３個の戸パネルが前後に重なるので、閉じ操作すべき戸パネル（上記の例では後側の戸パネル）を間違いやすいうえ、最前面の前側の戸パネルを閉じ操作すると、３個の戸パネルが前後に重なった状態のままで閉じ側へ移動する。つまり、前側（又は後）の戸パネルは中間の戸パネルの左右いずれか一側方に限って突出できるだけで、両者の位置の入れ換えを行おうとしても、前後に重なる状態を越えて他側方へ突出できる訳ではない。
【０００５】
３個の各戸パネルがピンを介して無端帯と一体化してあるので、戸パネルの上下レールに対する建て込みが難しく、施工に多くの手間と時間を要する。この点を改善した提案が特公昭５８−４０６３４号公報にみられる。そこでは、上レールを複数の戸パネルに予め組み付けておき、各戸パネルを下レールに嵌め込んだ後、上レールを戸枠上部のベース枠に締結して戸パネルを建て込む。しかし、この場合にも各戸パネルに上レールを予め組む必要があり、その組み込みに多くの手間が掛かる点で根本的な解決策とは言い難い。上レールとは別に、上レールを取り付けるための専用のベース枠を余分に要し、その分だけ連動引き戸のコストが高く付く。
【０００６】
この発明の目的は、内外両面に係合歯を備えた無端帯と、無端帯に係合するラック体とを機構要素にして、複数の戸パネルを左右勝手の無い状態で自由に連動開閉できる連動引き戸を提供することにある。この発明の他の目的は、前側あるいは後側の戸パネルを左右勝手のない状態で自由に開閉できる、３個以上の戸パネルを備えた連動引き戸を提供することにある。この発明の更に他の目的は、戸パネルの建て込みを通常の引き戸と同様にごく簡単に行え、施工に要する手間と時間を著しく減らすことができる連動引き戸を提供することにある。
【０００７】
【課題を解決するための手段】
この発明の連動引き戸は、複数個の戸パネルＰ１・Ｐ２・Ｐ３が、上下レール２・３のいずれか一方に組み込んだ連動機構４で連動開閉可能に支持してある。連動機構４は、各戸パネルＰ１〜Ｐ３に対応して、上レール２又は下レール３で移動自在に案内支持したスライド枠Ｓ１・Ｓ２・Ｓ３と、少なくとも１個のスライド枠Ｓ２で回転自在に軸支した左右の一対のギヤ１０・１０と、両ギヤ１０・１０に巻き掛け装着されて内外面に係合歯１１ａ・１１ｂを有する無端帯１１と、無端帯１１に隣接する他のスライド枠Ｓ１・Ｓ３に固定されて、無端帯１１の外面の係合歯１１ｂにかみ合うラック体１２とを含む。各スライド枠Ｓ１〜Ｓ３と、各戸パネルＰ１〜Ｐ３とは、連結具２７を介して連結してある。前後に隣接する戸パネルＰ１〜Ｐ３どうしは、隣接相手に対して前後に重なる開放位置と、隣接相手の左右両端のそれぞれから外側方へ突出する閉じ位置との間で連動開閉できるようにしたものである。
【０００８】
具体的には、前側の戸パネルＰ１と、中間の戸パネルＰ２と、後側の戸パネルＰ３とを、それぞれ上レール２に設けた連動機構４で連動開閉可能に走行案内する。中間の戸パネルＰ２を支持するスライド枠Ｓ２には、一対のギヤ１０・１０と無端帯１１とを配設し、前後の戸パネルＰ１・Ｐ３を支持するスライド枠Ｓ１・Ｓ３にラック体１２を配設する。
【０００９】
連結具２７は、戸パネルＰ１〜Ｐ３に埋設固定したケース２９と、ケース２９で出没自在に支持した連結軸３０と、連結軸３１をケース２９の外方へ向かって進出付勢するばね３２とを含む。各スライド枠Ｓ１〜Ｓ３に、連結軸３０を受け入れる連結穴２０を設ける。以て連結軸３０を連結穴２０に差し込み係合して、各戸パネルＰ１〜Ｐ３を各スライド枠Ｓ１〜Ｓ３と同行移動可能に連結する。
【００１０】
上下いずれか一方のレール２の内面の前後中央には、中間の戸パネルＰ２のスライド枠Ｓ２を案内する中レール枠１４を設ける。中レール枠１４の前後には、前後の戸パネルＰ１・Ｐ３のスライド枠Ｓ１・Ｓ３を支持する前レール枠１３と後レール枠１５とを前後対称に設ける。中間のスライド枠Ｓ２には、無端帯１１と、無端帯１１を支持する一対のギヤ１０とを配置する。無端帯１１に対して前後に対向する前後のスライド枠Ｓ１・Ｓ３の左右両端には、それぞれに短尺のラック体１２を配置する。連動機構４の全体を上レール２の内部空間に組み込んで、上レール２と連動機構４とを１個のユニットとして構成する。戸パネルＰ１〜Ｐ３の重量は、戸パネルＰ１〜Ｐ３の下部に設けた戸車５を介して下レール３で支持し、戸パネルＰ１〜Ｐ３の上部を連動機構４を介して上レール２で走行案内する。
【００１１】
【作用】
内外面に係合歯１１ａ・１１ｂを有する無端帯１１と、外面の係合歯１１ｂにかみ合うラック体１２とを主たる機構要素にして連動機構４が構成されていると、無端帯１１側の戸パネルＰ２と、ラック体１２側の戸パネルＰ１・Ｐ３とは、各戸パネルＰ１〜Ｐ３どうしが無端帯１１の直線移行部の一側端から外側方へ突出する閉じ状態と、直線移行部の他側端から外側方へ突出する閉じ状態とのいずれにも自由に切り換えることができる。つまり左右勝手のない状態で各戸パネルＰ１〜Ｐ３を連動開閉できる。
【００１２】
前後および中間の３個の戸パネルＰ１〜Ｐ３で連動引き戸を構成する場合には、中間の戸パネルＰ２を支持するスライド枠Ｓ２に一対のギヤ１０・１０と無端帯１１とを配設することにより、連動機構４が複雑になるのを避けて、連動引き戸の製造に要するコストを減らすことができる。
【００１３】
ばね３２で進出付勢した連結軸３０を、スライド枠Ｓ１〜Ｓ３に設けた連結穴２０に差し込み係合して、スライド枠Ｓ１〜Ｓ３と戸パネルＰ１〜Ｐ３とを同行移動可能に連結する形態によれば、連動機構４を戸パネルＰ１〜Ｐ３とは分離した状態で一方のレール２に予め組むことができるうえ、連結軸３０を連結穴２０に当てがい、各戸パネルＰ１〜Ｐ３をスライド枠Ｓ１〜Ｓ３側へ押し込み操作することで、各戸パネルＰ１〜Ｐ３の建て込み作業を終了でき、施工に要する手間を著しく軽減できる。
【００１４】
一方のレール、例えば上レール２と連動機構４とを１個のユニットとして構成すると、上レール２を戸枠１に固定した後、各戸パネルＰ１〜Ｐ３を連結具２７を介して対応するスライド枠Ｓ１〜Ｓ３に連結することで、連動引き戸を組み上げることができ、施工現場における組み立ての手間を減少できるうえ、連動引き戸の中心構造である連動機構４を、製造工場において正確に能率良く組み立てることができる。前後のスライド枠Ｓ１・Ｓ３の左右両端に短尺のラック体１２を配置するのは、ラック体１２の中間部を省略して、その分だけラック体１２の製作コストを節約するためである。戸パネルＰ１〜Ｐ３の重量を戸車５を介して下レール３に負担させ、連動機構４を上レール２の側に組み込んであると、連動機構４に作用する重量負荷を大幅に軽減して、各戸パネルＰ１〜Ｐ３を軽快に連動開閉できる。
【００１５】
【実施例】
図１ないし図５は本発明の連動引き戸の実施例を示しており、連動引き戸は３個の戸パネルＰ１・Ｐ２・Ｐ３で構成されている。図２において３個の戸パネルＰ１〜Ｐ３は、戸枠１に固定した上レール２と下レール３とでそれぞれスライド開閉自在に案内支持してあり、上レール２に設けた連動機構４で各戸パネルＰ１〜Ｐ３を連動して開閉操作できる。各戸パネルＰ１〜Ｐ３の下端両側には戸車５が埋設固定してある。戸車５は各戸パネルＰ１〜Ｐ３の重量を負担した状態で下レール３に設けたＶ字状のレール溝に沿って往復移動できる。前側および後側の戸パネルＰ１・Ｐ３の前面左右には、それぞれ取手６が設けてある。
【００１６】
図３において連動機構４は、上レール２で移動自在に支持した３個のスライド枠Ｓ１〜Ｓ３と、前後中央のスライド枠Ｓ２で支持した左右一対のタイミングプーリからなるギヤ１０・１０と、両ギヤ１０・１０に巻き掛け装着したタイミングベルトからなる無端帯１１と、無端帯１１の外面の係合歯１１ｂにかみ合うラック体１２とからなる。無端帯１１の内外面には、それぞれ係合歯１１ａ・１１ｂが一定ピッチ置きに突設してある。
【００１７】
図４において上レール２は、下向きに開口するアルミニウム合金製の条材からなり、その内面の前後中央に中レール枠１４が一体に突設されているとともに、中レール枠１４の前後に前レール枠１３と後レール枠１５とが一体に突設されている。中レール枠１４はレール上壁の内面に突設した断面Ｌ字形の一対の縦リブで形成する。前レール枠１３は、レール前壁に対向する断面Ｌ字形の縦リブと、レール前壁の上下に突設した２個の横リブとを有する逆Ｆ字状に形成する。後レール枠１５は前レール枠１３と前後対称に形成してある。中レール枠１４で中間に位置するスライド枠Ｓ２を支持し、前後のレール枠１３・１５で前後のスライド枠Ｓ１・Ｓ３をそれぞれ支持する。
【００１８】
前側のスライド枠Ｓ１は、角筒状のアルミニウム合金製の条材からなり、その前面上部に支持壁１６を突設し、筒壁後面に断面Ｃ字形の溝１７を設ける。支持壁１６の左右両端寄りの前後面にそれぞれローラ１８を遊転自在に軸支する。筒壁前面の左右両端寄りには、直方体状のスライド片１９をビスで締結固定する。スライド片１９は滑性および耐摩耗性に優れるプラスチック材で形成する。スライド枠Ｓ１の筒壁下面の左右両端寄りに連結穴２０が通設してある。ローラ１８は前レール枠１３の縦リブと上方の横リブとで走行案内され、スライド片１９は前レール枠１３の下方の横リブとレール前壁とでスライド案内される。これにより、スライド枠Ｓ１は上レール２の左右長手方向へ自由に往復移動できる。後側のスライド枠Ｓ３は、前側のスライド枠Ｓ１を前後に反転した点が異なるだけで、ローラ１８やスライド片１９、あるいは連結穴２０を前側のスライド枠Ｓ１と同様に設けてある。
【００１９】
中間のスライド枠Ｓ２は、それぞれ上向きに開口する断面コ字形の上枠２２および下枠２３を上下に重ね、両枠２２・２３をビス４０で締結して形成する。上枠２２の前後面の左右両端寄りにはローラ１８を遊転自在に軸支する。ローラ１８は中レール枠１４の一対の縦リブで走行案内されており、これで、スライド枠Ｓ２は上レール２の左右長手方向へ自由に往復移動できる。上枠２２の左右長さは下枠２３の左右長さより大きく寸法設定しておく。下枠２３の左右端から突出する上枠２２の側端下面にギヤ１０・１０を配置し、これらをベアリング２４を介して軸２５で遊転自在に軸支する。各ギヤ１０の下端面には無端帯１１の抜け落ちを防ぐフランジ２６が設けてある。下枠２３の下面壁の左右両端寄りには、先のスライド枠Ｓ１・Ｓ３と同様に連結穴２０を通設する。
【００２０】
左右の両ギヤ１０に無端帯１１を巻き掛け装着した状態において、前後のスライド枠Ｓ１・Ｓ３の各溝１７は無端帯１１の外周面と前後に対向している。これら両溝１７の左右両端にそれぞれ左右一対の短尺のラック体１２を嵌め込みビスで締結固定する。ラック体１２が無端帯１１の直線移行部を通過するとき、無端帯１１は短尺のラック体１２から離れる向きに撓み変形しようとする。この変形を阻止して、ラック体１２と無端帯１１との係合状態を確実に維持するために、直線移行部の内面に下枠２３を配置し、その前後面で無端帯１１の前後内方への変形を規制している。
【００２１】
各戸パネルＰ１〜Ｐ３を対応するスライド枠Ｓ１〜Ｓ３に連結するために、それぞれの戸パネルＰ１〜Ｐ３の上端面の左右両端寄りに連結具２７を装着する。図１において連結具２７は、プラスチック成形品からなる有底筒状のケース２９と、ケース２９で出没自在に支持した連結軸３０と、連結軸３０の上端に遊転自在に装着した縦ローラ３１と、ケース２９内に配置されて連結軸３０を上外側方へ向けて進出付勢する圧縮コイル形のばね３２とからなる。ケース２９の上端にはフランジ３３が張り出してあり、このフランジ３３より下方の筒部分を戸パネルＰ１〜Ｐ３に形成した装着穴に打ち込んで固定する。縦ローラ３１は凸字状に形成してあり、その上部に上すぼまりテーパー状の軸部３１ａを有する。
【００２２】
上レール２と連動機構４とは事前に組み立てて１個のユニットに構成して、施工現場へ搬入する。従って、施工時には上レール２および下レール３を戸枠１に締結固定したうえで、各戸パネルＰ１〜Ｐ３を対応するスライド枠Ｓ１〜Ｓ３に連結しながら建て込むだけでよく、施工の手間を著しく省くことができる。
【００２３】
具体的には、各戸パネルＰ１〜Ｐ３に連結具２７を装着する。次に、例えば後側の戸パネルＰ３を斜めに支持して、縦ローラ３１の軸部３１ａを対応するスライド枠Ｓ３の連結穴２０に当てがい、戸パネルＰ３の全体をばね３２の付勢力に抗して上レール２側へ押し上げ、戸パネルＰ３を垂直姿勢にしながら戸車５を下レール３のレール溝に落とし込む。同様にして、中間の戸パネルＰ２および前側の戸パネルＰ１を、対応するスライド枠Ｓ２・Ｓ１の連結穴２０とレール溝３ａとに嵌め込んで建て込みを終了する。
【００２４】
上記のように一対のギヤ１０・１０で支持した無端帯１１と、無端帯１１の外面の係合歯１１ｂに係合するラック体１２とを主な機構要素とした連動機構４によれば、前後のスライド枠Ｓ１・Ｓ３に設けた一対のラック体１２のうち、左右いずれか一方のラック体１２が無端帯１１に係合している限りは、３個のスライド枠Ｓ１〜Ｓ３を連動して開閉できるので、左右勝手の別なく各戸パネルＰ１〜Ｐ３を開閉できる。
【００２５】
いま、図５（ａ）に示すように、前側の戸パネルＰ１が右端に位置し、後側の戸パネルＰ３が左端に位置して、戸枠１の開口面が閉じられているとする。この状態から前側の戸パネルＰ１を左方へ開き操作すると、後側の戸パネルＰ３は戸枠１の側枠で受け止められてその位置を維持し続ける。しかし、中間の戸パネルＰ２と前側の戸パネルＰ１とは、無端帯１１とラック体１２とを介して連結された状態になっているので、両パネルＰ１・Ｐ２は後側の戸パネルＰ３に対してそれぞれ開き方向へ移動する。このとき、無端帯１１は前側の戸パネルＰ１の開量相当分だけギヤ１０・１９で回転案内されて周回移動し、後側のスライド枠Ｓ３に固定したラック体１２とかみ合いながら開き方向へ移動する。そのため中間の戸パネルＰ２は前側の戸パネルＰ１の開き量の半分だけ開き方向へ移動する。前側の戸パネルＰ１を全開放操作すると、３個の戸パネルＰ１〜Ｐ３は図５（ｂ）に示すように前後に重なって、２個の戸パネルＰ１・Ｐ２の分だけ開口面を開放できる。
【００２６】
上記の開放状態から前側の戸パネルＰ１を右方へ閉じ操作すると、戸枠１の開口面を閉止できるが、後側の戸パネルＰ３を閉じ操作しても同様の結果が得られる。この閉じ操作を行う場合には、後側の戸パネルＰ３を閉じ側へ移動操作することにより、図５（ｃ）に示すように中間の戸パネルＰ２を連動移動させて戸枠１の開口面を閉止できる。つまり、前後の戸パネルＰ１・Ｐ３は、それぞれ中間の戸パネルＰ２の左右いずれかの側からでも外側方へ突出でき、前側の戸パネルＰ１が戸枠１の左端に位置する状態と、右端に位置する状態とのいずれでも、位置の入れ換えが行え、左右勝手の別を考慮する必要がない。
【００２７】
図６は連動引き戸の別実施例を示す。そこでは各スライド枠Ｓ１〜Ｓ３の下面に垂直の取付壁３５を突設して連結具２７とした。取付壁３５は各戸パネルＰ１〜Ｐ３の上端に設けたスリット３６に差し込み、取付壁３５と戸パネルＰ１〜Ｐ３とをビス３７で締結して、各戸パネルＰ１〜Ｐ３をスライド枠Ｓ１〜Ｓ３を介して上レール２で吊持状に支持した。中間のスライド枠Ｓ２はアルミニウム合金製の条材で形成し、上枠２２と下枠２３および取付壁３５を一体に形成した。この場合には、戸パネルＰ１〜Ｐ３の下部に戸車５に代わる振れ止め具を設け、振れ止め具を下レール３で案内支持する。この振れ止め具としては、先の実施例で説明した連結具２７を適用できる。
【００２８】
連動引き戸は２個の戸パネルで構成できる。例えば上記の実施例における中間の戸パネルＰ２と、前後いずれか一方の戸パネルＰ１（又はＰ３）とで引き戸を構成し、対応するスライド枠Ｓ２とＳ１（又はＳ３）との間に、無端帯１１およびギヤ１０と、ラック体１２とを配置する。もちろん３個を越える場合には隣り合うスライド枠に、無端帯１１とラック体１２とを交互に配設する。上記の実施例において、前後のスライド枠Ｓ１・Ｓ３に無端帯１１を配置し、中間のスライド枠Ｓ２にラック体１２を設けることはできるが、連動機構４の構造が複雑になるのを避けられない。
【００２９】
ラック体１２はスライド枠Ｓ１・Ｓ３の全長にわたって設けることができる。連動機構４は下レール３側に組むことができる。連結具２７はその連結軸３０の突端を直接連結穴２０に直接係合してもよい。ローラ１８は４個以上設けることができる。
【００３０】
【発明の効果】
この発明では、一対のギヤ１０・１０に巻き掛けた無端帯１１と、無端帯１１の外面の係合歯１１ｂにかみ合うラック体１２とを主な機構要素にして連動機構４を構成し、前後に隣接する戸パネルＰ１〜Ｐ３どうしの位置の入れ換えを左右方向に自由に行えるようにした。従って、左右勝手の別なく各戸パネルＰ１〜Ｐ３を自由に開閉できる連動引き戸が得られ、使用者は戸枠１の左右端の必要とする側を速やかに開放して、物品の出し入れや戸枠１の通過を簡便に行える。左右勝手がないので、単一種の連動引き戸を右勝手用の引き戸としても、左勝手用の引き戸としても適用でき、施工現場における左右勝手の間違いによる混乱が避けられ、その商品管理も容易化できる。
【００３１】
連動機構４を例えば上レール２に組込んで１個のユニットとして構成した連動引き戸によれば、戸パネルＰ１〜Ｐ３の建て込みが容易に行え、施工に要する手間と時間を減少し、その分だけ施工費用を削減できる。工場において、連動機構４を上レール２に組むことができるので、施工現場で組み立てを行う場合に比べて連動機構４を正確に組め、連動引き戸の動作不良を一掃できる。

BACKGROUND OF THE INVENTION
The present invention relates to an interlocking sliding door that can be opened and closed simultaneously by opening and closing the door panel at one side in a sliding door constituted by a plurality of door panels.
[0002]
[Prior art]
An interlocking sliding door using a pinion and a rack as mechanical elements is known from Japanese Patent Publication No. 57-52473. Japanese Patent Publication No. 58-33354 discloses an interlocking sliding door having an endless belt such as a belt or a chain as a mechanism element. There, a sliding door is constituted by three door panels that overlap in the front and rear, sprocket gears are arranged on both sides of the upper end surface of the intermediate door panel, and a chain is wound around both gears. Each of the front and rear door panels is connected to the linear transition portion of the chain so as to be able to accompany it. When the door panel at one end is opened and closed, the other door panels can be simultaneously opened and closed.
[0003]
[Problems to be solved by the invention]
The sliding door having the endless belt as a mechanism element connects and fixes the front and rear door panels to the ends of the straight transition portion of the endless belt, so that the front and rear door panels are both ends of the front or rear straight transition portion of the endless belt. It can only reciprocate between them. Therefore, for example, when the front door panel is set as the opening start end, the opening direction of the sliding door is specified as either the right hand or the left hand. Specifically, when the front door panel is located on the right front of the middle door panel, the rear door panel is located on the left behind the middle door panel, and the entire sliding door closes the door opening. If the front door panel is opened, the sliding door can only be used as a left-open type.
[0004]
Such a restriction can be solved by opening one of the front door panel and the rear door panel as a starting edge. However, when the sliding door is fully opened, the three door panels overlap in the front and back, so it is easy to mistake the door panel to be closed (the rear door panel in the above example), and the front door panel on the forefront is When the closing operation is performed, the three door panels move to the closing side with the front and back overlapping. In other words, the front (or rear) door panel can protrude only on either the left or right side of the middle door panel, and even if you try to switch the position of both, It is not possible to protrude.
[0005]
Since each of the three door panels is integrated with the endless belt via a pin, it is difficult to build the door panel with respect to the upper and lower rails, and a lot of work and time are required for the construction. A proposal for improving this point can be found in Japanese Patent Publication No. 58-40634. In this case, the upper rail is assembled in advance to a plurality of door panels, and after each door panel is fitted into the lower rail, the upper rail is fastened to the base frame at the upper part of the door frame and the door panel is built. However, in this case as well, it is necessary to assemble an upper rail in each door panel in advance, and it is difficult to say that this is a fundamental solution in that much time is required for its incorporation. Apart from the upper rail, an extra base frame for mounting the upper rail is required, which increases the cost of the interlocking sliding door.
[0006]
An object of the present invention is to freely open and close a plurality of door panels without using left and right hands by using an endless belt provided with engaging teeth on both inner and outer surfaces and a rack body engaged with the endless belt as a mechanism element. The purpose is to provide an interlocking sliding door. Another object of the present invention is to provide an interlocking sliding door having three or more door panels that can freely open and close the front or rear door panel without any left-right hand. Still another object of the present invention is to provide an interlocking sliding door in which the door panel can be built up as easily as a normal sliding door, and the labor and time required for construction can be significantly reduced.
[0007]

The slide frames S1 to S3 and the door panels P1 to P3 are connected via a connector 27. The door panels P1 to P3 adjacent to each other in the front and rear can be interlockedly opened and closed between an open position that overlaps with the adjacent opponent in the front and back and a closed position that protrudes outward from each of the left and right ends of the adjacent opponent. It is.
[0008]
Specifically, the front door panel P1, the middle door panel P2, and the rear door panel P3 are travel-guided by the interlock mechanism 4 provided on the upper rail 2 so as to be interlocked and openable. A pair of gears 10 and 10 and an endless belt 11 are arranged on the slide frame S2 that supports the middle door panel P2, and the rack body 12 is attached to the slide frames S1 and S3 that support the front and rear door panels P1 and P3. Arrange.

The connection tool 27 includes a case 29 embedded and fixed in the door panels P1 to P3, a connection shaft 30 supported so as to be able to protrude and retract in the case 29, and a spring 32 that urges and urges the connection shaft 31 outward of the case 29. including. A connecting hole 20 for receiving the connecting shaft 30 is provided in each of the slide frames S1 to S3. Thus, the connecting shaft 30 is inserted into and engaged with the connecting hole 20, and the door panels P1 to P3 are connected to the slide frames S1 to S3 so as to be movable together.
[0010]
An intermediate rail frame 14 for guiding the slide frame S2 of the intermediate door panel P2 is provided at the front and rear center of the inner surface of either the upper or lower rail 2. Before and after the middle rail frame 14, a front rail frame 13 and a rear rail frame 15 that support the slide frames S1 and S3 of the front and rear door panels P1 and P3 are provided symmetrically. An endless belt 11 and a pair of gears 10 that support the endless belt 11 are arranged on the intermediate slide frame S2. Short rack bodies 12 are disposed on the left and right ends of the front and rear slide frames S1 and S3 facing the endless belt 11, respectively. The entire interlocking mechanism 4 is incorporated in the internal space of the upper rail 2, and the upper rail 2 and the interlocking mechanism 4 are configured as one unit. The weight of the door panels P1 to P3 is supported by the lower rail 3 via the door wheel 5 provided at the lower part of the door panels P1 to P3, and the upper part of the door panels P1 to P3 is run by the upper rail 2 via the interlocking mechanism 4. invite.
[0011]
