【発明の属する技術分野】
本発明は、ガイドレールの長手方向に沿う複数個の扉体を伸縮自在に連結した複連引き戸式門扉に関するものである。
【０００２】
【従来の技術】
ガイドレールの長手方向に沿う複数個の扉体を伸縮自在に連結した複連引き戸式門扉には、従来、実開平４−２７０９９号公報に記載のようなものがある。
この複連引き戸式門扉は、ガイドレールの長手方向に沿う複数個の扉体を前後方向に近接させて配置し、この複数個の扉体の内、最前側に配置された扉体の両端下部に、ガイドレール上を走行する台車を設け、この扉体の後側に順次隣接して配置される各扉体の一端側の下部に、ガイドレール上を走行する台車を、他端側に、隣接する前側の扉体の案内溝に嵌合して伸縮方向に案内される案内部材を夫々設けている。
そして、この複連引き戸式門扉は、最前側の扉体をガイドレールに沿って伸縮方向に走行させた時に、この扉体に近い扉体から順次ガイドレールに沿って走行しながら伸縮するようになっている。
【０００３】
【発明が解決しようとする課題】
従来の複連引き戸式門扉では、最前側の扉体を除く後側の各扉体には、その扉体の一端下部に台車を備えているが、他端側には台車を備えておらず、案内溝に嵌合する案内部材を介して前側の扉体によって伸縮自在に支持する構造を採っている。
このため、各扉体の案内溝及び案内部材に大きな負担がかかり、各扉体を収縮させて格納する場合や、各扉体を引き出して出入り口を閉鎖する場合に、各扉体が滑らかに伸縮せず、非常に大きな力を必要とする問題がある。従って、各扉体の案内溝及び案内部材が損傷し易くなると共に、格納や引き出し等に際しての伸縮操作が非常に重たくて煩わしく、しかも構造的にも各扉体の重量、長さ等が制約されると言う欠点がある。
本発明は、このような従来の課題に鑑み、各扉体の負担を軽減できると共に、格納や引き出し等に際しての伸縮操作を容易且つ軽快にでき、しかも各扉体の重量、長さ等も大にできる複連引き戸式門扉を提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明は、ガイドレール5 に沿って走行する複数個の扉体6,7 を前後方向に近接させて配置し、この複数個の扉体6,7 の内、前後方向の一端側の扉体6 をガイドレール5 に沿って伸縮方向に走行させた時に、この一端側の扉体6 に近い扉体7 から順次ガイドレール5 に沿って走行するように各扉体6,7 を伸縮自在に連結した複連引き戸式門扉において、各扉体6,7 の両端側下部に、ガイドレール5 に沿って走行する台車15,16 を夫々設け、この各台車15,16 上に、該台車15,16 上に固定された扉体6,7 の上部側を支持し且つ他の扉体6,7 がガイドレール5 の長手方向に相対移動自在に収まる支持枠17,18 を設け、前後に隣り合う扉体6,7 の伸縮方向に相対向する端部側の台車15,16 を、相手側の扉体6,7 の台車15,16 よりも相手側の扉体6,7 側に配置し、各台車 15,16 は扉体 6,7 から前後に突出する車輪枠 22,23 と、この車輪枠 22,23 の前後両端に取り付け台 24,25 を介して取り付けられた一対の車輪 13,14 とを備え、各支持枠 17,18 は各車輪枠 22,23 の前後両端から起立する支柱部 30,31 と、この支柱部 30,31 の上端を前後に連結する連結部 32,33 を備え、各取り付け台 24,25 は各車輪枠 22,23 と各支柱部 30,31 とに跨がって側面に当接して固定し、各扉体 6,7 は取り付け板 34 〜 37 を介して連結部 32,33 、車輪枠 22,23 に固定された上下一対の横枠 8,9 と、左右一対の縦枠 10,11 とを備えたものである。
【０００５】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳述する。
図１の（Ａ）及び（Ｂ）において、１はブロック塀等の構築物、２は出入口である。３は扉体格納部、４は戸当たり柱で、これら扉体格納部３と戸当たり柱４は、構築物１の内側の敷地内で出入り口２の両側に設けられている。５は前後一対のガイドレールで、扉体格納部３側から戸当たり柱４側に亘って出入り口２の地面側に左右方向に敷設されている。
【０００６】
６は第１扉体、７は第２扉体で、これら扉体６，７は前後一対のガイドレール５間の略中央部に、ガイドレール５の長手方向に沿って配置されると共に、相対向する端部同士がガイドレール５の長手方向にオーバーラップするように前後に近接して配置されている。
【０００７】
各扉体６，７は上下一対の横枠８，９と左右一対の縦枠１０，１１とを備え、その上下の横枠８，９間に多数の縦桟１２を配置して構成されている。各扉体６，７には、その長手方向の両端下部に、前後両側に車輪１３，１４を有する台車１５，１６が装着されると共に、各台車１５，１６上に、各扉体６，７の両端部を支持する支持枠１７，１８が固定されている。
【０００８】
ガイドレール５は、図４乃至図７に示すように、台車１５，１６の車輪１３，１４が転動する車輪転動部１９と、この車輪転動部１９上を転動する車輪１３，１４の横振れを規制する横振れ規制部２０とを一体に備え、出入り口２の地面に平行に敷設されている。なお、一対のガイドレール５間には、横振れ規制部２０の上端と一致するようにコンクリート２１が充填されている。
【０００９】
台車１５，１６は、図２乃至図７に示すように、各扉体６，７の両端部から前後に突出する矩形筒状の車輪枠２２，２３と、この車輪枠２２，２３の前後両端部に取り付け台２４，２５を介して上下調節自在に取り付けられた一対の車輪１３，１４とを備え、その車輪１３，１４がガイドレール５の車輪転動部１９上を長手方向に沿って転動するようになっている。
【００１０】
各扉体６，７の伸縮方向に相対向する端部側の台車１５，１６、即ち、各扉体６，７の連結側の台車１５，１６は、図２及び図３に示すように、各扉体６，７を引き出して伸長させる時に、両扉体６，７が台車１５，１６を介して互いに連結されるように、相手側の扉体７，６の台車１６，１５よりも相手側の扉体７，６側に配置されている。
【００１１】
つまり、両台車１５，１６の連結部分側では、第１扉体６と第２扉体７との端部同士がオーバーラップ状態にあり、その第１扉体６側の台車１５は、第２扉体７の端部よりも第２扉体７側に、また第２扉体７側の台車１６は、第１扉体６の端部よりも第１扉体６側に夫々配置されている。
なお、取り付け台２４，２５は、車輪枠２２，２３と、この車輪枠２２，２３の前後両端部から起立する支持枠１７，１８とに跨がって固定されており、この取り付け台２４，２５に車輪ブラケット２６，２７等を介して車輪１３，１４が取り付けられている。
【００１２】
また各車輪枠２２，２３の両側には、伸縮方向の両側に突出するストッパー２８，２９が前後方向に所定間隔をおいて固定されている。各ストッパー２８，２９は、硬質ゴム、合成樹脂等の適宜材料により構成され、伸縮時に相対向するストッパー２８，２９同士が互いに当接するようになっている。
【００１３】
各扉体６，７は略同一長さであり、また第１扉体６側の両台車１５間の間隔は第２扉体７側の両台車１６間の間隔よりも短くなっている。
各支持枠１７，１８は、図４乃至図７に示すように、その内側に配置された扉体６，７の上部側を支持すると共に、この各扉体６，７に近接して配置された相手側の扉体６，７を互いに収納可能な大きさの門型状に構成されている。各支持枠１７，１８は、各台車１５，１６の車輪枠２２，２３の前後両端から垂直状に起立する支柱部３０，３１と、この両支柱部３０，３１の上端を前後に連結する連結部３２，３３とから構成されている。
【００１４】
各扉体６，７は、図４乃至図７に示すように、上下の取り付け板３４，３５、３６，３７を介して支持枠１７，１８の連結部３２，３３と車輪枠２２，２３とに固定されている。各取り付け板３４，３５、３６，３７はＬ字状であって、上側の取り付け板３４，３６は連結部３２，３３の下面に、下側の取り付け板３５，３７は車輪枠２２，２３の上面に夫々ネジで固定されている。また各取り付け板３４，３５、３６，３７は扉体６，７の各横枠８，９にネジで固定されている。
【００１５】
各扉体６，７の連結部分側の支持枠１７，１８及び車輪枠２２，２３には、図２乃至図７に示すように、隣り合う相手側の扉体７，６を伸縮方向に案内する前後一対の案内ローラ３８，３９、４０，４１が設けられている。各案内ローラ３８，３９、４０，４１は、相手側の扉体７，６の上下両端部の各横枠８，９を前後両側から挟むように前後一対設けられており、支持枠１７，１８の連結部３２，３３及び車輪枠２２，２３に固定された縦軸４２により回転自在に支持されている。
【００１６】
なお、各支持枠１７，１８の内、第１扉体６の戸当たり柱４に近い先導側の支持枠１７と、第２扉体７の扉体格納部３に近い吊り元側の支持枠１８には、案内ローラ３８，３９、４０，４１等は設けられていない。また第１扉体６の戸当たり柱４側の縦枠１０，１１には、把手４３と施錠手段４４とが設けられている。
この２連引き戸式門扉は、出入り口２の開放時には、両扉体６，７を収縮させた状態で、両扉体６，７を構築物１の内側の扉体格納部３に格納している。
【００１７】
この格納状態から各扉体６，７を伸長させて出入り口２を閉鎖する場合には、次のようにして行う。即ち、第１扉体６の先導側の支持枠１７に装着された把手４３を把持して、第１扉体６を図１の（Ｂ）のａ矢示方向に戸当たり柱４側へと引っ張ると、先ず第１扉体６がガイドレール５に沿って戸当たり柱４側に移動する。
【００１８】
この時、第１扉体６の両端部に台車１５があり、その車輪１３が各ガイドレール５の車輪転動部１９上を転動する。しかし、第２扉体７の両端部にも車輪１４付きの台車１６があり、この台車１６を介して第２扉体７がガイドレール５上に支持されているため、第１扉体６の戸当たり柱４側への走行時に、第２扉体７の重量が第１扉体６側にかかることもない。
【００１９】
従って、第１扉体６はガイドレール５に沿って容易且つ円滑にａ矢示方向へと走行できる。つまり、各扉体６，７の重量は、各扉体６，７毎に夫々独立して台車１５，１６により支持する構造となっているため、第１扉体６は軽く滑らかに走行できる。
【００２０】
この第１扉体６の走行時に、各扉体６，７は相手側の扉体７，６の連結側の台車１５，１６上に固定された支持枠１７，１８内を相対的に引き出し方向に移動するが、各扉体６，７は、その連結側の台車１５，１６の車輪枠２２，２３及び支持枠１７，１８に設けられた前後一対の案内ローラ４０，４１、３８，３９により前後両側から挟持しながら案内される。
【００２１】
このため、各扉体６，７の両端部に夫々台車１５，１６を設け、各扉体６，７が別々にガイドレール５上を走行するようにしているにも拘わらず、第１扉体６の引き出し時に、その引き出し方向が第２扉体７と若干ずれて両扉体６，７が屈折するようなことがなく、ガイドレール５に沿って両扉体６，７を略真っ直ぐに引き出すことができる。
【００２２】
第１扉体６の長さ分だけ第１扉体６を戸当たり柱４側に引き出すと、その連結側の台車１５がストッパー２８，２９を介して第２扉体７の連結側の台車１６に当接して連結され、両扉体６，７が最大伸長状態となる。そして、更に第１扉体６を戸当たり柱４側に移動させると、両扉体６，７が連結側の両台車１５，１６を介して連結された状態でガイドレール５に沿って一体に移動し、構築物１の内側の扉体格納部３から出入り口２側へと引き出される。
【００２３】
この時にも、各扉体６，７の両端部に夫々台車１５，１６があり、その台車１５，１６により各扉体６，７の重量が支持されているため、各扉体６，７はガイドレール５に沿って容易且つ円滑に走行することができる。
出入り口２を閉鎖した状態では、図１の（Ｂ）に実線で示すように、第１扉体６の先導側が戸当たり柱４に当接し、施錠手段４４で第１扉体６を戸当たり柱４側に施錠する。
【００２４】
この状態から第１扉体6 を反ａ矢示方向にその長さ分だけ移動させると、第１扉体6 が第２扉体7 に重なって出入り口2 の左半分を開放でき、また逆に第２扉体7 を戸当たり柱4 側へとａ矢示方向に移動させると、図１の（Ｂ）に仮想線で示すように、第２扉体7 が第１扉体6 に重なって出入り口2 の右半分を開放できる。
【００２５】
第１扉体6 を扉体格納部3 まで反ａ矢示方向に移動させると、両扉体6,7 を収縮させて扉体格納部3 を格納し出入り口2 を開放できる。
なお、実施形態では、２連式として説明したが、３連式以上の場合にも同様に実施可能である。
また各扉体6,7 は斜めに傾斜させて設けても良い。
【００２６】
【発明の効果】
本発明によれば、ガイドレール5 に沿って走行する複数個の扉体6,7 を前後方向に近接させて配置し、この複数個の扉体6,7 の内、前後方向の一端側の扉体6 をガイドレール5 に沿って伸縮方向に走行させた時に、この一端側の扉体6 に近い扉体7 から順次ガイドレール5 に沿って走行するように各扉体6,7 を伸縮自在に連結した複連引き戸式門扉において、各扉体6,7 の両端側下部に、ガイドレール5 に沿って走行する台車15,16 を夫々設け、この各台車15,16 上に、該台車15,16 上に固定された扉体6,7 の上部側を支持し且つ他の扉体6,7 がガイドレール5 の長手方向に相対移動自在に収まる支持枠17,18 を設け、前後に隣り合う扉体6,7 の伸縮方向に相対向する端部側の台車15,16 を、相手側の扉体6,7 の台車15,16 よりも相手側の扉体6,7 側に配置し、各台車 15,16 は扉体 6,7 から前後に突出する車輪枠 22,23 と、この車輪枠 22,23 の前後両端に取り付け台 24,25 を介して取り付けられた一対の車輪 13,14 とを備え、各支持枠 17,18 は各車輪枠 22,23 の前後両端から起立する支柱部 30,31 と、この支柱部 30,31 の上端を前後に連結する連結部 32,33 を備え、各取り付け台 24,25 は各車輪枠 22,23 と各支柱部 30,31 とに跨がって側面に当接して固定し、各扉体 6,7 は取り付け板 34 〜 37 を介して連結部 32,33 、車輪枠 22,23 に固定された上下一対の横枠 8,9 と、左右一対の縦枠 10,11 とを備えているので、次のような顕著な効果を奏する。
【００２７】
１）各扉体6,7 の両端下部に、ガイドレール5 に沿って走行する台車15,16 を夫々設けており、各扉体6,7 を夫々別々に台車15,16 により支持する構成であるため、従来のように互いに隣り合う一方の扉体6,7 で他方の扉体6,7 の端部側を支持する必要がなく、各扉体6,7 の相手側に対する負担を大幅に軽減できると共に、格納や引き出し等に際しての伸縮操作を容易且つ円滑にできる。
【００２８】
２）一方の扉体6,7 で他方の扉体6,7 の端部側を支持する必要がないので、各扉体6,7 の重量を重くし、又は長さを長くすることが可能である。このため、出入り口2 に応じて各扉体6,7 の重量、長さ等を自由に決定できる利点がある。

３）各扉体6,7 の両端下部に台車15,16 を設ける一方、その各台車15,16 上に支持枠17,1 8 を設けて扉体6,7 の上部側を支持しているため、各扉体6,7 の台車15,16 上での安定性が向上し、門扉全体の強度を大にできる。
特に各台車15,16 上に、各扉体6,7 の上部側を支持する支持枠17,18 を設けているため、各扉体6,7 の上部側に前後方向の外力が作用した場合でも、扉体6,7 と台車15,16 との固定部に過大な応力が直接作用することもなく、その固定部の負担を軽減することができる。従って、扉体6,7 、その他の各部の変形や損傷を確実に防止できる。
【００３０】
４）各支持枠17,18 内に他の扉体6,7 が相対移動自在に収まっており、前後に隣り合う扉体6,7 の伸縮方向に相対向する端部側の台車15,16 を、相手側の扉体7,6 の台車16,15 よりも相手側の扉体7,6 側に配置しているので、扉体6,7 の引き出し時に対向端部側の台車15,16 を介して各扉体6,7 を連結でき、各扉体6,7 の対向端部側を連結する連結手段を別途設ける必要がなくなると共に、各扉体6,7 の連結部分側の強度を大にでき、各扉体6,7 を円滑に引き出すことができる。
