Description

【０００１】
【発明の属する技術分野】
本発明は、上・中・下の３段の扉開閉装置で大型の扉を開口部に簡単に取り付ける扉の取り付け構造に関する。
【０００２】
【従来の技術】
扉が通常の高さの場合、上下２個の蝶番で取り付けていたが、例えば扉の枠外高が８尺高のような大型の物になると、上下２個の扉開閉装置では扉の反りや強度の面で不安があった。そこで、このような大型の扉の取り付けは上中下の３段にて扉開閉装置を用いることが一般的に行われている。しかしながら扉開閉装置を上中下の３段で用いると反りや強度の面で問題を解消を図ることができるが、大型扉では取り付け方法が非常に煩雑となり施工時間がかかっていた。
【０００３】
【発明が解決しようとする課題】
本発明はこのような従来例の問題点に鑑みてなされたもので、大型扉を開口部に簡単に取り付けることができる３個１組の扉開閉装置を用いた扉の取り付け構造の開発をその技術的解決課題とする。

前記扉開閉装置(1a)(1b)(1c)は、開口部(5)側に取り付けられた固定側開閉部材(2a)(2b)(2c)と扉(4)側に取り付けられた移動側開閉部材(3a)(3b)(3c)とで構成され、
下段の扉開閉装置(1a)の固定側開閉部材(2a)に設けられた軸取付部(6a)に上向きの枢着軸(7a)が設けられると共に前記移動側開閉部材(3a)に前記枢着軸(7a)が回動自在に枢着される軸受部(8a)が設けられており、
中・上段の前記扉開閉装置(1b)(1c)にあっては、いずれか一方の固定側開閉部材(2b)(2c)の円筒状の軸取付部(6b)(6c)に上向きの可動枢着軸(7b)(7c)が設けられ、前記可動枢着軸(7b)(7c)が回転可能に挿入される軸受部(8b)(8c)がいずれか他方の移動側開閉部材(3b)(3c)に設けられており、

【０００５】
「請求項２」の扉(4)の取り付け構造は、その図１(a)に示す変形例で「３組の扉開閉装置(1a)(1b)(1c)を用いて扉(4)を上・中・下の３段で開口部(5)に取り付ける扉(4)の取り付け構造であって、
前記扉開閉装置(1a)(1b)(1c)は、開口部(5)側に取り付けられた固定側開閉部材(2a)(2b)(2c)と扉(4)側に取り付けられた移動側開閉部材(3a)(3b)(3c)とで構成され、
下段の扉開閉装置(1a)の移動側開閉部材(3a)に設けられた軸取付部(6a)に下向きの枢着軸(7a)が設けられると共に前記固定側開閉部材(2a)に前記枢着軸(7a)が回動自在に枢着される軸受部(8a)が設けられており、
中・上段の前記扉開閉装置(1b)(1c)にあっては、いずれか一方の前記固定側開閉部材(2b)(2c)の円筒状の軸取付部(6b)(6c)に上向きの可動枢着軸(7b)(7c)が設けられ、前記可動枢着軸(7b)(7c)が回転可能に挿入される軸受部(8b)(8c)がいずれか他方の移動側開閉部材(3b)(3c)に設けられており、
中・上段の前記扉開閉装置(1b)(1c)の前記可動枢着軸(7b)(7c)は、前記軸取付部(6b)(6c)に対して下方から挿脱することによってそれぞれに対応する前記軸受部(8b)(8c)に対して挿脱可能となっており、前記可動枢着軸 (7b)(7c) の中間部分には係合爪 (41b)(41c) が設けられたスライド円筒部 (40b)(40c) が取り付けられており、

【０００６】
本発明の扉(4)の取り付け構造は、３組の扉開閉装置(1a)(1b)(1c)を用いて扉(4)を上・中・下の３段で開口部(5)に取り付けるのであるから、反りを発生させることなく大型の扉(4)を強固に取り付けることができる。加えてその施工において、下段の扉開閉装置(1a)の枢着軸(7a)を固定とし、中・上段の扉開閉装置(1b)(1c)の枢着軸(7b)(7c)を軸受部(8b)(8c)に対して挿脱可能とする事で、中・上段の枢着軸(7b)(7c)の挿入側先端が軸取付部(6b)(6c)内に没入した状態にし、この状態で扉(4)を開口部(5)に対して若干傾けてセットし、残る下段の枢着軸(7a)をこれに対応する下段の軸受部(8a)に挿入し(図１参照)、続いて扉(4)を起こし、前記前記中・上段の枢着軸(7b)(7c)を軸受部(8b)(8c)に下から挿入することで簡単に大型の扉(4)を開口部(5)に取り付けることができるようになる(図２、３参照)。
【０００７】
また、大型扉(4)の取り付けの際に枢着軸(7b)(7c)を仮固定しておくことで、前述のように扉(4)を開口部(5)に対して若干傾けてセットした後、扉(4)を垂直に起こした時、軸受部(8b)(8c)に接触接触させることなく上・中・下の３段の扉開閉装置(1a)(1b)(1c)を一人の作業者で簡単に合致させる事が出来、続いて仮固定を解除することで枢着軸(7b)(7c)を軸受部(8b)(8c)に挿入・固定することができ、大型扉(4)の取付作業性を高めることができる。
【０００８】
「請求項３」は「請求項１又は２」における軸受部(8a)(8b)(8c)に関し「軸受部(8a)(8b)(8c)が軸取付部(6a)(6b)(6c)に対して近接・離間可能となっている」ことを特徴とするもので、これにより大型扉(4)を開口部(5)に取り付けた後、軸受部(8a)(8b)(8c)と軸取付部(6a)(6b)(6c)との間に発生した間隙を解消することができる。
【０００９】
【発明の実施の形態】
以下、本発明を図示実施例に従って詳述する。扉開閉装置(1a)(1b)(1c)は、図１〜３に示すように、例えば８尺高の大型扉(4)を上・中・下の３段にて開口部(5)に取り付けるためのものである。本実施例では、枢着軸(7a)が固定のものを下段の扉開閉装置(1a)に用い、枢着軸(7b)(7c)がスライドするものを上・中段の扉開閉装置(1b)(1c)として用いた。勿論、このような使用方法に限られるものでなく、逆に枢着軸(7a)が固定のものを上段の扉開閉装置(1c)に用い、枢着軸(7a)(7b)がスライドするものを中・下段の扉開閉装置(1a)(1b)としてもよい。
【００１０】
まず、扉開閉装置(1a)(1b)(1c)を順に説明する。下段の扉開閉装置(1a)は図４〜６に示す通りで、下段の扉開閉装置(1a)の固定側開閉部材(2a)はプレートケース(21)と固定部材(22a)とで構成されている。プレートケース(21)はダイカスト材で開口部(5)の縦框部分にそれぞれ取り付けられるものであり、図５に示すように、固定部材(22a)の舌片部(23a)が図示しない機構によってプレートケース(21)に対して矢印(S)で示すように挿脱方向及び、矢印(M)で示すように開口部(5)の縦框部分の取付面に対して近接離間方向に若干移動して軸取付部(6a)の位置調整ができるようになっている。なお、プレートケース(21)は、いずれの固定側開閉部材(2a)(2b)(2c)においても共通して使用されている。
【００１１】
また、下段の固定部材(22a)は、前記舌片部(23a)と、舌片部(23a)の一端を円筒状に形成した軸取付部(6a)並びにこの軸取付部(6a)の上端部分に取り付けられ、軸取付部(6a)の上端から突出している固定の枢着軸(7a)とで構成されている。
【００１２】
一方、下段の移動側開閉部材(3a)は、図４及び図６に示すように、移動側プレート(29a)と移動側プレート(29a)の先端部分に設けられた軸受部(8a)とで構成されている。軸受部(8a)は移動側プレート(29a)の先端部分が円筒状に形成された円筒部(30a)、前記円筒部(30a)の切欠部(31a)に嵌め込まれ、切欠部(31a)に設けた回り止め部(32a)に係合し、中心に雌ねじ(33a)が形成されているナット(34a)、前記ナット(34a)に螺装されている雄ネジ(35a)、軸受部(8a)の下部開口から挿入された軸受筒体(36a)および円筒部(30a)の外面を覆う化粧筒体(37a)とで構成されている。
【００１３】
前記軸受筒体(36a)は上端閉塞、下面が開口した樹脂製のもので、雄ネジ(35a)の先端が軸受筒体(36a)の閉塞上端(38a)に当接している。前記ナット(34a)の高さは、切欠部(31a)の切り欠き高さにほぼ等しく、ナット(34a)の外周面には回止切欠(39a)が設けられている。切欠部(31a)は円筒部(30a)の一部を窓状に切り欠いたもので、切り欠き部分の先端に形成された切り残し部分が回り止め部(32a)であり、ナット(34a)の回止切欠(39a)が嵌め込まれている。
【００１４】
中段の扉開閉装置(1b)の固定側開閉部材(2b)も、図１〜３に示すように、プレートケース(21)と固定部材(22b)とで構成されており、前記同様固定部材(22b)の舌片部(23b)がプレートケース(21)に対して舌片部(23b)が矢印(S)で示すように挿脱方向及び、矢印(M)で示すように開口部(5)の縦框部分の取付面に対して近接離間方向に若干移動して軸取付部(6b)の位置調整ができるようになっている。中段の固定部材(22b)も、前記舌片部(23b)と、舌片部(23b)の一端を円筒状に形成した軸取付部(6b)並びにこの軸取付部(6b)に設けられた挿脱可能な枢着軸(7b)とで構成されている。
【００１５】
枢着軸(7b)の挿脱機構は、図７に示すように、枢着軸(7b)の中間部分に取り付けられ、係合爪(41b)が設けられたスライド円筒部(40b)、軸取付部(6b)の下端に取り付けられ、枢着軸(7b)のスライド孔(42b)が穿設されている軸保持筒部(43b)、軸保持筒部(43b)とスライド円筒部(40b)との間に配設され、枢着軸(7b)を軸取付部(6a)の上端から突出させる方向に押圧付勢している圧縮バネ(44b)、軸取付部(6b)の側面の上下２カ所に形成され、前述の係合爪(41b)が係合する突出側係合孔部(45b)および没入側係合孔部(46b)ならびに突出側係合孔部(45b)と没入側係合孔部(46b)をつなぎ、係合爪(41b)の移動時に係合爪(41b)が通過する通過溝(47b)とで構成されている。
【００１６】
一方、中段の移動側開閉部材(3b)は下段の移動側開閉部材(3a)と同一形状であるので、煩雑さを避けるため、同一部材には末尾の小文字アルファベットを(a)から(b)に変えた同一符号を付して説明に代える。
【００１７】
上段の扉開閉装置(1c)は中段の扉開閉装置(1b)と逆で、図８に示すように、固定側開閉部材(2c)に軸受部(8c)が設けられ、移動側開閉部材(3c)に挿脱可能な枢着軸(7c)が設けられている。上段の扉開閉装置(1a)の構成部材は中段の扉開閉装置(1b)の構成部材と同じであるので、煩雑さを避けるために、同一部材には末尾の小文字アルファベットを(b)から(c)に変えた同一符号を付して説明に代える。
【００１８】
大型扉 (4) を開口部 (5) に取り付ける際には、前述の３組の扉開閉装置(1a)(1b)(1c)の固定側開閉部材(2a)(2b)(2c)を開口部(5)の縦框の所定位置に上・中・下の３段に取り付け、移動側開閉部材(3a)(3b)(3c)を大型扉(4)の蝶着側端部の所定位置に上・中・下の３段に取り付ける。続いて、上・中２段の移動側開閉部材(3b)(3c)の可動枢着軸(7b)(7c)を図９ (a) の状態から若干回転させて係合爪(41b)(41c)を突出側係合孔部(45b)(45c)から離脱させた後、図９ (b) に示すように、この係合爪 (41b)(41c) を通過溝(47b)(47c)を通って没入側係合孔部(46b)(46c)の高さまで移動させ、図９ (c) に示すように、再度可動枢着軸(7b)(7c)を若干回転させて係合爪(41b)(41c)を没入側係合孔部(46b)(46c)に係合させて仮固定する。この時、圧縮バネ(44b)(44c)は圧縮され、且つ可動枢着軸(7b)(7c)の先端部分は軸取付部(6b)(6c)内に完全に没入している。
【００１９】
然る後、大型扉(4)を持ち上げ、図１のように大型扉(4)を若干倒した状態で下段の固定側開閉部材(2a)の上向きの固定枢着軸(7a)を下段の移動側開閉部材(3a)の軸受部(8a)に挿入する。この状態で図２のように大型扉(4)を垂直に立て、上・中２段の扉開閉装置(1b)(1c)の軸受部(8b)(8c)と軸取付部(6b)(6c)とを一致させ、続いて上・中２段の扉開閉装置(1b)(1c)の可動枢着軸(7b)(7c)を下側から逆方向に若干回転させると、没入側係合孔部(46b)(46c)から係合爪(41b)(41c)が外れると同時に圧縮バネ(44b)(44c)の弾発力にて係合爪(41b)(41c)が通過溝(47b)(47c)を通って突出側係合孔部(45b)(45c)に移動する。これにより可動枢着軸(7b)(7c)が軸取付部(6b)(6c)から突出して軸受部(8b)(8c)に入り込み、下端のストッパ(49b)(49c)が軸取付部(6b)(6c)に当接してストップし、図３のように３組の扉開閉装置(1a)(1b)(1c)による大型扉(4)の開口部(5)への取り付けが行われる。
【００２０】
最後に、３組の扉開閉装置(1a)(1b)(1c)のいずれかの軸受部(8a)(8b)(8c)と軸取付部(6a)(6b)(6c)との間に隙間が発生した場合には、隙間が発生している扉開閉装置(1a)(1b)(1c)の軸受部(8a)(8b)(8c)の頂部に形成されている通孔(48a)(48b)(48c)（図４、図７、図８）からドライバを挿入し、軸受部(8a)(8b)(8c)内の雄ネジ(35a)(35b)(35c)を回転させ、軸受筒体(36a)(36b)(36c)方向に螺進させて軸受筒体(36a)(36b)(36c)を軸受部(8a)(8b)(8c)の下端から突きだし、軸受部(8a)(8b)(8c)の下端を軸取付部(6a)(6b)(6c)の上端に当接させ、前記隙間を解消する。また、軸受部(8a)(8b)(8c)と軸取付部(6a)(6b)(6c)の中心線が一致しない場合には、固定部材(22a)(22b)(22c)に対して舌片部(23a)(23b)(23c)を矢印(S)及び／又は矢印(M)方向に移動させ、中心線が一致するように調整する。
【００２１】
前記の場合は下段の扉開閉装置(1a)に固定枢着軸(7a)を用いた場合を説明したが、逆に上段の扉開閉装置(1c)に固定枢着軸(7c)を用いて扉(4)を吊り下げるようにして取り付けてもよい。前者の場合は、最初の取り付けが下段で行われるため目視しやすく作業しやすい。また、前者においては下から可動枢着軸(7b)(7c)の挿脱を行うことが出来るので、背の高い大型扉(4)の取付が簡単に行える。
【００２２】
なお、図の実施例では中段の扉開閉装置(1b)の固定側開閉部材(2b)を上向きの枢着軸(7b)、移動側開閉部材(3b)を軸受部(8b)とし、上段の扉開閉装置(1c)の固定側開閉部材(2c)を軸受部(8c)、移動側開閉部材(3c)を上向きの枢着軸(7c)としたが、勿論これに限られず、図示していないがこれとは逆に中段の扉開閉装置(1b)の固定側開閉部材(2b)を軸受部(8b)、移動側開閉部材(3b)を上向きの枢着軸(7b)とし、上段の扉開閉装置(1c)の固定側開閉部材(2c)を上向きの枢着軸(7c)、移動側開閉部材(3c)を軸受部(8c)としてもよい。いずれにせよ３段の扉開閉装置(1a)(1b)(1c)を使用するが、支持は下段の扉開閉装置(1a)と中段の扉開閉装置(1b)或いは下段の扉開閉装置(1a)と上段の扉開閉装置(1c)とで２点支持する事になる。
【００２３】
また、図１(a)に示すように下段の扉開閉装置(1a)の移動側開閉部材(3a)の軸取付部(6a)の枢着軸(7a)を下向きにし、固定側開閉部材(2a)の軸受部(8a)でこの枢着軸(7a)で回動自在に枢着するようにしてもよい。
【００２４】
【発明の効果】
本発明にあっては３組の扉開閉装置を用いて扉を上・中・下の３段で開口部に取り付けるのであるから、反りを発生させることなく大型の扉を強固に取り付けることができる。加えてその施工において、３段の扉開閉装置を使用するが、支持は下段の扉開閉装置と中段の扉開閉装置或いは下段の扉開閉装置と上段の扉開閉装置とで２点支持する事になるので、簡単に大型の扉を開口部に取り付けることができるようになる。また、枢着軸が軸受部に対する脱出位置において仮固定されるようにしておけば、作業効率を高めることができる。更に、軸受部を軸取付部に対して近接・離間可能とすることで、大型扉の取り付け後、軸受部と軸取付部との間に発生した間隙を解消することができる。
