Description

【０００１】
【発明の属する技術分野】
本発明は、建物の玄関のドアや引戸等の通常の窓や出入口に開閉自在に設けられる建具に関する。
【０００２】
【背景技術】
図１に示すように、一部に採光性や意匠性等を確保するための開口部１１０Ａが形成されたパネル体１１０を備えるドア１００が知られている。
このようなドア１００では、図１１，１２に示すように、開口部１１０Ａに配置される面材としての複層ガラス１２０は、ねじ１３３で連結された室内側保持部材１３１および室外側保持部材１３２により、パネル体１１０の室内外の両面側から挟持されて保持されている。なお、意匠性を確保するため、室内側保持部材１３１には、ねじ１３３の頭部がドア１００の表面に露出しないように隠すためのカバー材１３４が取付られている。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来のドア１００は、各保持部材１３１，１３２に対してねじ孔加工やねじ止め作業が必要になるため、生産性および組立作業性が悪いという問題があった。さらに、意匠性の確保のためにカバー材１３４を使用したので、比較的部材点数が多くなり製造コストが高くなるという問題もあった。
【０００５】
また、図１１に示すように、従来のドア１００では、室外面側の複層ガラス１２０に対して雨水等の水が当たると、複層ガラス１２０を伝って室外側保持部材１３２と複層ガラス１２０との間にその水が入り込むことがあった。
このため、室外側保持部材１３２のガラス保持溝の部分と下面とに排水用の孔１３５Ａ，１３５Ｂを設け、その孔１３５Ａ，１３５Ｂを介して、図１１の一点鎖線の矢印１３６に示す経路で排水を行っていた。
また、室内側保持部材１３１と室外側保持部材１３２との接合面から室内側に水が浸入しないように、接合面にスポンジを挟んだり、シーリング処理等を行って室内面側への漏水防止処理を行っていた。
【０００６】
しかしながら、このような排水構造では、デザイン性を向上するために複雑な断面形状で押出成形された室外側保持部材１３２に排水孔１３５Ａ，１３５Ｂを加工しなければならず、加工が煩雑であるという問題があった。
【０００７】
また、各保持部材１３１，１３２の接合面の漏水防止処理が必要となり、各保持部材１３１，１３２をねじ止めして組み立てる際の作業性が低下するという問題もあった。
さらに、作業者の熟練度等によっては、この漏水防止処理の品質を常に一定に確保できない場合があり、その際には、浸入してきた水が芯材１３７の上部に溜まらずに、図１１中の一点鎖線の矢印１３８に示す経路で、室内面側に漏水してしまうという問題もあった。
【０００８】
本発明の目的は、室内面側への漏水を確実にかつ容易に防止可能な建具を提供することにある。
【０００９】
【課題を解決するための手段】
本発明の建具は、開口部を有するパネル体と、前記開口部に設けられる面材と、この面材を前記パネル体の室内面側および室外面側から挟持する面材挟持部材とを備える建具であって、前記開口部の下側で、かつ前記パネル体の内部には、前記面材と面材挟持部材との間に浸入する水を受けるとともに、前記パネル体の外部側に排水可能な排水溝が設けられ、前記パネル体は、上框、下框および竪框により四周枠組みされるフレームと、このフレームの室内面および室外面に貼設されるパネルと、このパネル間に配置された断熱ボードとを有し、前記排水溝は前記開口部の下側に配置される前記断熱ボードの上面に形成され、この断熱ボードの左右両端には竪框が当接して設けられ、これらの竪框は前記排水溝で受けられる水を排出可能に形成され、前記下框はこれらの竪框の下側に配置され、前記竪框から排出される水を受けて前記パネル体の外部側に排水可能な排水孔が形成されていることを特徴とするものである。
【００１０】
このような構成によれば、例えば、室外面側の面材に雨水が当たって面材と室外側保持部材との間に雨水が浸入しても、開口部の下部に設けられた排水溝によりパネル体の外部へと雨水が排出されるので、室内面側への漏水を確実に防止できる。特に、短寸のピース状に形成された取付部材で、所定間隔毎に各保持部材同士を連結するために各保持部材間に隙間があるような場合でも、室内面側への漏水を確実に防止して室外側に排水できる。
【００１１】
また、例えば、複雑な断面形状で押出成形された室外側保持部材に排水用の孔加工をする場合にくらべて、パネル体は比較的単純な形状であるため、容易に排水加工ができる。
さらに、各保持部材間にスポンジを挟む等の漏水防止処理が不要なので作業性を向上できる。
【００１３】
さらに、排水溝で受けた水が竪框を通って下框に達し、その下框に形成された排水孔から排水できるので、パネル体の表面を伝って水が流れることがないから、パネル体の表面を拭く等の清掃作業を軽減するとともに、パネル体の意匠性および耐候性も確保できる。
また、断熱ボードの上面に排水溝を形成しているので、別途排水溝を構成する樋材などを用意する必要が無く、部品点数を軽減できてコストを低減できる。
【００１６】
また、前記面材挟持部材は、室内面側から前記面材を保持する室内側保持部材と、室外面側から前記面材を保持する室外側保持部材と、これらの室内側保持部材および室外側保持部材の間に配置されて各保持部材を連結する取付部材とを有し、前記取付部材は、所定間隔毎に取り付けられる短寸のピース状に形成されていることが好ましい。
【００２３】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
【００２４】
本発明の建具である断熱ドア１は、図１に示すように、いわゆる片開きドアであり、建物の玄関開口部に設けられるドア枠２と、ドア枠２内に配置されるパネル構造体（戸板）３とを備えて構成され、主にパネル構造体３に断熱性が付与される。
【００２５】
ドア枠２は、図２または図３に示すように、それぞれアルミの押出形材からなる上枠２１、下枠２２および左右の縦枠２３を四周枠組みしビス止めされて形成される。
【００２６】
パネル構造体３は、図１〜図３に示すように、略中央部に開口部３１Ａを有するパネル体３１と、開口部３１Ａに設けられる面材としての複層ガラス３２と、パネル体３１の室内面側および室外面側から複層ガラス３２を挟持する面材挟持部材である額縁３３とを備える。
【００２７】
パネル体３１は、図２または図３に示すように、それぞれ断面コ字状のアルミ押出形材または鉄骨材等からなる上框３１１、下框３１２および左右２つの竪框３１３を四周枠組みし、その内側に補強用の竪框３１３Ａを含んで形成されるフレーム３１４と、このフレーム３１４の室内面および室外面に貼設されるパネルである鋼板３１７，３１８と、これらの鋼板３１７，３１８の間に配置されるペーパーハニカムコアやウレタン等の断熱性を有する芯材としての断熱ボード３１５と、上エッジ材３１９、下エッジ材３２０および左右の縦エッジ材３２１とを備え、その略中央部に複層ガラス３２を取り付けるための開口部３１Ａを有する。
そして、このペーパーハニカムコア等を含む断熱ボード３１５により、パネル体３１に断熱性能が付与され、パネル体３１での室内外側の熱伝導が行われにくくなっている。
【００２８】
左右の竪框３１３は、断面コ字状であり、図３中の右側に示すように、一方の竪框３１３の中空部にはドア枠２の縦枠２３に対して係脱する錠３２２が収容される。また、錠３２２を進退させて縦枠２３に係脱可能にするドアノブ３２３が設置され、これらの錠３２２およびドアノブ３２３は、竪框３１３にビス止めされている。また、図３中の左側に示すように、他方の竪框３１３には、縦エッジ材３２１を介してドア枠２との接続を行うヒンジ３２４がビス止めされている。
【００２９】
額縁３３は、図３の要部の拡大図である図４にも示すように、室内面側から複層ガラス３２を保持する室内側保持部材である内額縁３４と、室外面側から複層ガラス３２を保持する室外側保持部材である外額縁３５と、これらの額縁３４，３５の間に配置され各額縁３４，３５を連結する取付部材３６と、図２に示すように、この取付部材３６と同様に額縁３４，３５の間に配置され各額縁３４，３５を連結する一体型取付部材３７とを有する。
【００３０】
内額縁３４と外額縁３５との間には、図５に示すように、取付部材３６がパネル体３１の開口部３１Ａの左右両側に所定の間隔で７個ずつ配置され、一体型取付部材３７が、上下両側に１個ずつ配置される。
そして、内額縁３４と外額縁３５とは、図４に示すように、取付部材３６によって連結されて離隔しないように係止され、気密材３４０，３５０を介して複層ガラス３２を挟持している。
【００３１】
内額縁３４および外額縁３５は、アルミ押出形材からなる上額縁３４Ａ，３５Ａ、下額縁３４Ｂ，３５Ｂおよび２本の縦額縁３４Ｃ，３５ＣをＬ字形ブラケットを介して互いに４５度接合等することにより予め四周枠組みされている。
【００３２】
内額縁３４と外額縁３５とが対面する側（裏面側）において、内額縁３４には嵌合部としての室内側嵌合凹部３４１が形成され、外額縁３５にも嵌合部としての室外側嵌合凹部３５１が形成されている。
【００３３】
室内側嵌合凹部３４１は、爪部３４２を備えており、この爪部３４２には、自身の内部側に向かって傾斜する傾斜面３４２Ａが形成されており、後述する取付部材３６の室内側係止部３６１Ａを案内することにより嵌合し易くなっている。
【００３４】
一方、室外側嵌合凹部３５１も、爪部３５２を備えているが、この爪部３５２は、前述の爪部３４２のような傾斜面は備えておらず、パネル体３１の室内外面と平行に形成されている。
【００３５】
取付部材３６は、図６にも示すように、樹脂製であるとともに、内額縁３４を係止可能な室内側取付部材３６１と、外額縁３５を係止可能な室外側取付部材３６２とを備える。
【００３６】
室内側取付部材３６１には、室内側嵌合凹部３４１と嵌合し、かつ内額縁３４および外額縁３５が離隔する方向に動かないように係止可能な嵌合係止部である室内側係止部３６１Ａが形成されている。
【００３７】
これらの室内側係止部３６１Ａは、室内側嵌合凹部３４１の爪部３４２の傾斜面３４２Ａに沿うとともに、爪部３４２を案内する傾斜面３６１Ｂを有し、正確な嵌合部位から多少ずれていても室内側嵌合凹部３４１の爪部３４２を案内して嵌合するように形成される。
【００３８】
一方、室外側取付部材３６２には、室外側嵌合凹部３５１と嵌合し、かつ内額縁３４および外額縁３５が離隔する方向に動かないように係止可能な嵌合係止部である室外側係止部３６２Ａが形成されている。
室外側係止部３６２Ａは、室外側嵌合凹部３５１の爪部３５２を案内する傾斜面３６２Ｂを有し、正確な嵌合部位から多少ずれていても室外側嵌合凹部３５１の爪部３５２を案内して嵌合するように形成される。
【００３９】
また、図６において、室内側取付部材３６１と室外側取付部材３６２とは室内外方向と直交する方向である上下方向にスライドすることにより、着脱可能に形成されている。この際、室外側取付部材３６２の下端には、室内側取付部材３６１を下側から支持する支持部３６３が形成されている。これにより室内側取付部材３６１は、室外側取付部材３６２から下方向に外れないようになっている。
【００４０】
一体型取付部材３７は、図２に示すように、内額縁３４の室内側嵌合凹部３４１の爪部３４２に案内されて室内側嵌合凹部３４１に嵌合可能な嵌合突部３７１と、外額縁３５の室外側嵌合凹部３５１に嵌合および係止可能な嵌合係止部３７２とが一体成形されている。
【００４１】
嵌合突部３７１は、室内外方向に延長されて略板状に形成され、かつ互いに略平行に配置された２つの突片により構成されている。この嵌合突部３７１は、他の嵌合係止部３７２のように突起部分がないため、室内側嵌合凹部３４１の爪部３４２に係止されず、凹部３４１内に挿入されている。従って、嵌合突部３７１と室内側嵌合凹部３４１とは、互いを室内外方向に相対移動させるだけで、着脱できるようになっている。一方、嵌合係止部３７２は、前述の室外側係止部３６２Ａと全く同様に形成されて、室外側嵌合凹部３５１に係止されている。
【００４２】
また、複層ガラス３２は、下側の一体型取付部材３７に載置されており、一体型取付部材３７の高さ寸法で複層ガラス３２の高さ位置を調節している。
【００４３】
図２に示すように、開口部３１Ａの下部に配置された断熱ボード（芯材）３１５の上面には、排水溝３１５Ａが断熱ボード３１５の全長に渡って形成されている。この排水溝３１５Ａが形成された断熱ボード３１５の左右両端は、図７にも示すように、竪框３１３，３１３Ａに当接しており、下框３１２および下エッジ材３２０の下面には、断熱ボード３１５の室外側へと繋がる排水孔３１２Ａが形成されている。
【００４４】
このため、図２、図５および図７の一点鎖線の矢印４００の経路で示すように、複層ガラス３２および外額縁３５の間からパネル体３１の内部に浸入した雨水は、排水溝３１５Ａによって受けられ、竪框３１３の内部および下框３１２の上部を通って排水孔３１２Ａから確実に室外側へと排出される。
【００４５】
以下、本実施形態における複層ガラス３２を開口部３１Ａに取付ける方法を説明する。なお、一体型取付部材３７も取付部材３６と同様に取付けられるため、ここでは、説明を省略する。
図８に示すように、まず、予め外額縁３５の室外側嵌合凹部３５１に取付部材３６の室外側係止部３６２Ａとを嵌合させて装着しておく。
この外額縁３５をパネル体３１の室外面側の開口部３１Ａに挿入し、パネル体３１に両面テープ５１を用いて接着する。
【００４６】
次に、外額縁３５に気密材３４０を介して複層ガラス３２を配置し、パネル体３１の室内面側の開口部３１Ａに内額縁３４を挿入する。
その際、室内側係止部３６１Ａと室内側嵌合凹部３４１との嵌合部分は、内額縁３４の裏側になって視認できないが、室内側嵌合凹部３４１の爪部３４２に形成された傾斜面３４２Ａと、室内側係止部３６１Ａに形成された傾斜面３６１Ｂとにより、室内側嵌合凹部３４１と室内側係止部３６１Ａとが、正確な嵌合位置に案内される。
【００４７】
そして、図４に示すように、室内側係止部３６１Ａは、嵌合の際には自身の内側方向に変形し、嵌合した後にはバネ効果により元の位置に戻って嵌合される。この際、図８に示すように、図８中の距離Ｌ１よりもＬ２が大きくなるように形成するので、室内側係止部３６１Ａと室内側嵌合凹部３４１との係止はより強固なものとなる。なお、この嵌合強度は、例えば、室内側嵌合凹部３４１の爪部３４２間の間隔Ｌ１に対する室内側係止部３６１Ａ間の幅寸法Ｌ２を調整することなどで、適宜調整することができる。
また、内額縁３４には、気密性スポンジ５２が取り付けられ、この気密スポンジ５２をパネル体３１の室内面側に当接させて気密性を確保している。
以上のようにして、複層ガラス３２をパネル体３１に取り付ける。
【００４８】
また、例えば、複層ガラス３２の破損等により複層ガラス３２を交換したい場合には、図６に示すように、複層ガラス３２と外額縁３５との間に細長い治具４を差し込み、この治具４を上方に移動させて室内側取付部材３６１を上方へ移動させて、室内側取付部材３６１と室外側取付部材３６２とを外す。
この際、室内側取付部材３６１の室内側係止部３６１Ａは、内額縁３４の爪部３４２に対しても上方にスライド移動する。従って、治具４により室内側取付部材３６１のみが上方に移動する。
同様にして全ての室内側取付部材３６１を外せば、内額縁３４が開口部３１Ａから外れる。次に、破損した複層ガラス３２を取り除き、新しい複層ガラス３２を取り付け、外れた室内側取付部材３６１を外額縁３５に装着し、前述と同様に内額縁３４を取り付ける。このようにして複層ガラス３２を簡単に交換できる。
【００４９】
このような本実施の形態によれば、次のような効果が得られる。
（１）室内側嵌合凹部３４１の爪部３４２に傾斜面３４２Ａを形成し、室内側取付部材３６１の室内側係止部３６１Ａに傾斜面３６１Ｂを形成したので、室内側嵌合凹部３４１と室内側係止部３６１Ａとを嵌合する際に、室内側嵌合凹部３４１と室内側係止部３６１Ａとが正確な嵌合位置から多少ずれていても、傾斜面３４２Ａ，３６１Ｂに沿って自動的に正確な位置に補正されるため、室内側嵌合凹部３４１と室内側係止部３６１Ａとが視認できなくても簡単に嵌合できる。
【００５０】
（２）室内側係止部３６１Ａおよび室外側係止部３６２Ａにより、内額縁３４と外額縁３５とが離隔する方向に、額縁３４，３５同士を係止できるから、開口部３１Ａに額縁３４，３５を確実に取り付けることができる。ひいては、開口部３１Ａに複層ガラス３２を簡単かつ確実に挟持できる。
【００５１】
（３）内額縁３４と外額縁３５との間にスナップ（嵌合）方式で取り付けられる取付部材３６を設けて内額縁３４と外額縁３５とを連結したので、内額縁３４と外額縁３５とをねじ止めする必要がないから、組立作業の作業性を向上できる。そのうえ、ねじの頭部を隠すためのカバー材が不要なので、構成部材の点数を減少させて、製造コストおよび管理コストを抑えることができる。
【００５２】
（４）複層ガラス３２を交換する場合において、各嵌合凹部３４１，３５１と各係止部３６１Ａ，３６２Ａとの嵌合を外すことなく、各額縁３４，３５が分離されるので、開口部３１Ａから各額縁３４，３５を簡単に取り外して、複層ガラス３２を交換できる。そのうえ、ガラス３２の取り外し時に、各嵌合凹部３４１，３５１および各係止部３６１Ａ，３６２Ａの嵌合を外す必要がないので、その嵌合部分には比較的強固な嵌合構造を採用でき、複層ガラス３２の支持強度も向上できる。
【００５３】
（５）室内側取付部材３６１と室外側取付部材３６２とが上下にスライドして着脱可能なので、例えば、細長い治具４を用いて室内側取付部材３６１を上方に移動させれば、室内側取付部材３６１と室外側取付部材３６２とが外れ、内額縁３４が開口部３１Ａから簡単に外れるから、簡単に複層ガラス３２を交換できる。また、用途や目的に合わせて複層ガラス３２を他の意匠性の異なる面材等に任意に変更して、断熱ドア１の意匠性の向上を図ることもできる。
【００５４】
（６）室外側取付部材３６２に支持部３６３を形成したので、支持部３６３で室内側取付部材３６１を下側から支持すれば、室内側取付部材３６１に対して上方向への力を加えない限り、室外側取付部材３６２には常に下方向への重力が働いて室内側取付部材３６１と室外側取付部材３６２とが外れないから、額縁３３を開口部３１Ａに確実に取り付けることができる。さらに、摩擦力で室内側取付部材３６１および室外側取付部材３６２間の移動を規制する必要がないので、各取付部材３６１，３６２間の摩擦力を小さくでき、各取付部材３６１，３６２同士を小さな力でスライドさせて簡単に外すことができる。
【００５５】
（７）取付部材３６を熱伝導性の低い樹脂により形成したので、従来のように金属製の内額縁３４および外額縁３５が全周にわたって当接する場合に比べて、内額縁３４と外額縁３５との間の熱伝導を比較的抑えることができる。特に、短寸の取付部材３６を所定の間隔で配置し、内額縁３４と外額縁３５とを連結したので、連結した部分以外は内額縁３４と外額縁３５とは空気層を介して離れて配置され、より一層内額縁３４と外額縁３５との間の熱伝導を抑えることができる。これにより、断熱ドア１の断熱性をより向上できる。
【００５６】
（８）開口部３１Ａの下側に配置される断熱ボード３１５の上面に排水溝３１５Ａを設けたので、複層ガラス３２と外額縁３５との間に雨水が浸入しても、この雨水を排水溝３１５Ａで受けて、竪框３１３および下框３１２を介して排水孔３１２Ａからパネル体３１の外部へと排出できる。このため、室内側への漏水を確実に防止できる。
【００５７】
特に、本実施形態では、取付部材３６を短寸のピース状に形成し所定間隔毎に配置したため、額縁３４，３５の間に隙間が形成されるが、排水溝３１５Ａでこの雨水を全て受けられるので、室内面側への漏水を確実に防止して室外面側に排水できる。
【００５８】
（９）排水溝３１５Ａで受けた水が竪框３１３を通って下框３１２に達し、その下框３１２に形成された排水孔３１２Ａから排水できるので、パネル体３１の表面を伝って水が流れることがないから、パネル体３１の表面を拭く等の清掃作業を軽減できるとともに、パネル体の意匠性および耐候性も確保できる。
【００５９】
（１０）開口部３１Ａの下側に配置される断熱ボード３１５の上面に排水溝３１５Ａを設けたので、例えば、従来のような複雑な断面形状で押出成形された室外側保持部材に排水用の孔を施す場合に比べて、パネル体は比較的単純な形状であるため、容易に排水用の加工ができる。また、室内側保持部材および室外側保持部材間に、スポンジを挟む等の漏水防止処理が不要なので作業性を向上でき、かつ安価である。
【００６０】
（１１）さらに、芯材である断熱ボード３１５の上面に排水溝３１５Ａを形成したので、別途、排水溝を形成するための樋部材などを組み込む必要が無く、部品点数を少なくできてコストを低減できるとともに、組立作業性も向上できる。
【００６１】
なお、本発明は、前記実施の形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、図９に示すように、開口部３１Ａの下側に設けられる断熱ボード３１５の上面に図９中点線で示すような排水溝３１５Ｂを形成し、この排水溝３１５Ｂの下側にパネル体３１の外部へと通じる２つの孔３７０が形成されてもよい。なお、これらの孔３７０は２つに限らず任意の数でよい。ただし、前記実施形態のほうが、加工が容易で製造しやすい利点がある。
【００６２】
また、本実施形態では、開口部３１Ａ下側の断熱ボード３１５の上面に排水溝３１５Ａを形成したが、開口部３１Ａの下側で断熱ボード３１５の上側に開口側を上にしたコ字状の框を、左右の竪框３１３に当設するように配置してもよい。このようにすれば、パネル体３１の剛性を高めることもできる。
【００６３】
また、本実施形態では、室内側嵌合凹部３４１の爪部３４２に傾斜面３４２Ａを形成し、室内側係止部３６１Ａにも傾斜面３６１Ｂを形成したが、室内側係止部３６１Ａのみに傾斜面を形成してもよく、つまりは室内側嵌合凹部３４１の爪部３４２および室内側係止部３６１Ａの少なくとも一方に傾斜面が形成されればよい。
なお、室外側においても同様に、室外側嵌合凹部３５１の爪部３５２および室外側係止部３６２Ａの少なくとも一方に傾斜面が形成されればよい。
【００６４】
さらに、傾斜面は、室内側の嵌合部位と室外側の嵌合部位との少なくとも一方に形成されればよい。例えば、室外側嵌合凹部３５１の爪部３５２のみに傾斜面が形成されてもよく、この場合、予め室内側の嵌合部位については、視認しながら嵌合しておき、その後、この傾斜面に案内されて室外側嵌合凹部３５１と室外側係止部３６２Ａとが嵌合されればよい。
【００６５】
各取付部材３６１，３６２の係止部３６１Ａ，３６２Ａの形状としては、前記実施形態の形状に限らない。例えば、図１０に示す室内側係止部３６１Ａのように、爪部３４２に接する突起部分が傾斜面３６１Ｂと同様に斜めに形成されたものでもよい。このような形状にすれば、係止部３６１Ａと爪部３４２との嵌合強度が向上し、より大きな耐風圧が加わっても外れないようにすることができる。
【００６６】
さらに、本実施形態では、開口部３１Ａの左右に７個ずつ取付部材３６を配置したが、７個に限らず額縁同士を確実に取り付けられれば任意の数でよい。その際、取付部材３６の大きさも開口部３１Ａの全長に渡る長さのものでもよい。つまり、開口部３１Ａの全長よりも短いものであれば任意の長さでよい。
【００６７】
また、パネル体３１の開口部３１Ａの上下側には、一体型取付部材３７ではなく前述の取付部材３６が配置されてもよい。
【００６８】
本実施形態では、芯材として断熱ボード３１５を使用したが、断熱性のない芯材が使用されてもよく、目的や用途に合わせて適宜変更すればよい。
また、面材として複層ガラス３２を使用したが、これに限らず、ガラスや意匠性の異なるパネル等の面材であれば任意のものでよい。
【００６９】
また、各額縁３４，３５は、アルミ製のものを使用したが、これに限らず樹脂製等のその他の材料で形成されたものであってもよい。その際、各額縁３４，３５は、予め枠組みされるものに限らず、各枠材を別々にパネル体３１に取り付けてもよい。
【００７０】
取付部材３６を樹脂製としたが、金属材等のその他の任意の材料で形成されてもよく、その際には、特に金属に比べて熱を伝導しにくい材料で構成することが好ましい。このようにすれば、内額縁３４と外額縁３５との熱の伝導を抑えることができる。
【００７１】
本実施形態では、上下方向にスライドして取付部材３６を分離可能としたが、室内側取付部材３６１と室外側取付部材３６２とのどちらか一方に、上下方向から室内外方向に連続するＬ字状の溝を設け、他方にこの溝に沿ってスライドする突起を設けて、上下方向にスライドし、さらに室内外方向にスライドすることにより分離可能としてもよい。
取付部材３６には、支持部３６３を設けたが、凹凸等の加工を施すことによりスライドする部分の摩擦力を大きくすれば、支持部３６３はなくてもよい。
【００７２】

また、取付部材３６は、本実施形態のように２つに分離できるものでなく一体型のものでもよい。この場合でも、従来のようなねじ止めに比べれば、取付け作業性等を向上できる。
但し、一体型の取付部材３６を用いた場合には、室内側保持部材、室外側保持部材である額縁３４，３５と、取付部材３６との嵌合を外して額縁３４，３５を分離しなければならないが、前記実施形態のように構成すれば、この嵌合を外すことなく各額縁３４，３５を分離できて、複層ガラス３２を外しやすい利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a fitting that can be freely opened and closed at a normal window such as a door or a sliding door of a building or a doorway.
[0002]
[Background]
As shown in FIG. 1, there is known a door 100 including a panel body 110 in which an opening portion 110 A for securing daylighting property, designability, and the like is partially formed.
In such a door 100, as shown in FIGS. 11 and 12, the multi-layer glass 120 as the face material disposed in the opening 110 A is composed of an indoor holding member 131 and an outdoor holding member 132 connected by screws 133. Thus, the panel body 110 is sandwiched and held from both indoor and outdoor side surfaces. In order to secure the design, a cover material 134 for hiding the head of the screw 133 so as not to be exposed on the surface of the door 100 is attached to the indoor side holding member 131.
[0003]
[Problems to be solved by the invention]
However, the conventional door 100 has a problem in that productivity and assembly workability are poor because screw holes and screwing operations are required for the holding members 131 and 132. Furthermore, since the cover material 134 is used to ensure designability, there is a problem that the number of members is relatively increased and the manufacturing cost is increased.
[0005]
As shown in FIG. 11, in the conventional door 100, when water such as rainwater hits the multilayer glass 120 on the outdoor surface side, the outdoor holding member 132 and the multilayer glass are transmitted through the multilayer glass 120. The water sometimes entered between 120 and 120.
Therefore, drainage holes 135A and 135B are provided in the glass holding groove portion and the lower surface of the outdoor holding member 132, and the drainage is performed through the holes 135A and 135B along the path indicated by the dashed line arrow 136 in FIG. Had gone.
In addition, water is prevented from leaking into the indoor surface by inserting a sponge into the joint surface or performing a sealing process so that water does not enter the indoor side from the joint surface between the indoor side holding member 131 and the outdoor side holding member 132. Had gone.
[0006]
However, in such a drainage structure, the drainage holes 135A and 135B must be processed in the outdoor holding member 132 extruded with a complicated cross-sectional shape in order to improve the design, and the processing is complicated. There was a problem.
[0007]
In addition, it is necessary to prevent water leakage at the joint surfaces of the holding members 131 and 132, and there is a problem that workability when the holding members 131 and 132 are assembled by screwing is lowered.
Furthermore, depending on the skill level of the operator, the quality of this water leakage prevention process may not always be ensured. In this case, the infiltrated water does not collect on the upper part of the core material 137, and in FIG. There is also a problem that water leaks to the indoor surface side along the path indicated by the dashed-dotted arrow 138.
[0008]
 The present inventionEyesThe purpose is to provide a fitting capable of reliably and easily preventing water leakage to the indoor surface side.
[0009]
[Means for Solving the Problems]
 The joinery of the present invention includes a panel body having an opening, a face material provided in the opening, and a face material clamping member for clamping the face material from the indoor surface side and the outdoor surface side of the panel body. The water that enters between the face material and the face material sandwiching member is received below the opening and inside the panel body, and can be drained to the outside of the panel body. There is a drainThe panel body includes a frame that is framed around the upper and lower ridges and the heel, panels that are attached to the indoor and outdoor surfaces of the frame, and a heat insulating board that is disposed between the panels. The drainage grooves are formed on the upper surface of the heat insulation board disposed below the opening, and the right and left ends of the heat insulation board are provided with ridges in contact with the drainage grooves. The lower gutter is arranged under these gutters, and a drainage hole that receives water discharged from the gutter and drains it to the outside of the panel body is formed. FormedIt is characterized by that.
[0010]
 According to such a configuration, for example, even if rainwater hits the face material on the outdoor surface side and rainwater enters between the face material and the outdoor holding member, the drainage groove provided at the lower part of the opening Since rainwater is discharged to the outside of the panel body, water leakage to the indoor surface side can be reliably prevented. In particular, even in the case where there is a gap between the holding members in order to connect the holding members to each other at a predetermined interval with the mounting member formed in a short piece shape, water leakage to the indoor surface side is ensured. It can prevent and drain to the outdoor side.
[0011]
 Further, for example, the panel body has a relatively simple shape as compared with the case where the hole for drainage is drilled in the outdoor holding member extruded with a complicated cross-sectional shape, so that drainage can be easily performed.
Furthermore, workability can be improved because there is no need for water leakage prevention treatment such as sandwiching a sponge between the holding members.
[0013]
 furtherSince the water received in the drainage channel passes through the trough and reaches the bottom trough and can drain from the drain hole formed in the bottom trough, the water does not flow along the surface of the panel body, While reducing the cleaning work such as wiping the surface, the design and weather resistance of the panel body can be secured.
 Also,Insulation boardA drainage groove is formed on the top surface ofBecauseIn addition, it is not necessary to prepare a dredging material that constitutes a drainage groove separately, and the number of parts can be reduced and the cost can be reduced.
[0016]
The face material clamping member includes an indoor side holding member that holds the face material from the indoor surface side, an outdoor side holding member that holds the face material from the outdoor surface side, and the indoor side holding member and the outdoor side. It is preferable that the mounting member is disposed between the holding members to connect the holding members, and the mounting member is formed in a short piece shape that is attached at predetermined intervals.
[0023]

And the heat insulation performance is provided to the panel body 31 by the heat insulation board 315 containing this paper honeycomb core etc., and the heat conduction inside and outside the panel body 31 is difficult to be performed.
[0028]
The left and right hooks 313 have a U-shaped cross section, and as shown on the right side in FIG. Be contained. In addition, a door knob 323 that allows the lock 322 to move forward and backward to be engaged and disengaged with the vertical frame 23 is installed, and the lock 322 and the door knob 323 are screwed to the collar 313. Further, as shown on the left side in FIG. 3, a hinge 324 that is connected to the door frame 2 via a vertical edge member 321 is screwed to the other flange 313.
[0029]
As shown in FIG. 4 which is an enlarged view of the main part of FIG. 3, the frame 33 includes an inner frame 34 that is an indoor holding member that holds the multilayer glass 32 from the indoor surface side, and a multilayer from the outdoor surface side. An outer frame 35 that is an outdoor side holding member that holds the glass 32, an attachment member 36 that is arranged between the frame 34 and 35 and connects the frames 34 and 35, and as shown in FIG. Similarly to 36, it has an integral attachment member 37 arranged between the frames 34 and 35 and connecting the frames 34 and 35.
[0030]
Between the inner frame 34 and the outer frame 35, as shown in FIG. 5, seven mounting members 36 are arranged at predetermined intervals on the left and right sides of the opening 31A of the panel body 31, and are integrated mounting members 37. Are arranged one on each of the upper and lower sides.
As shown in FIG. 4, the inner frame 34 and the outer frame 35 are connected by the attachment member 36 and locked so as not to be separated from each other, and sandwich the multilayer glass 32 through the airtight members 340 and 350. Yes.
[0031]
The inner frame 34 and the outer frame 35 are obtained by joining the upper frame 34A, 35A, the lower frame 34B, 35B, and the two vertical frames 34C, 35C made of an aluminum extruded shape, 45 degrees to each other via an L-shaped bracket. A four-round framework is pre-set.
[0032]
On the side (back side) where the inner frame 34 and the outer frame 35 face each other, the inner frame 34 is formed with an indoor fitting recess 341 as a fitting portion, and the outer frame 35 also has an outdoor side as a fitting portion. A fitting recess 351 is formed.
[0033]
The indoor fitting recess 341 includes a claw portion 342, and the claw portion 342 is formed with an inclined surface 342A that is inclined toward the inner side of the claw portion 342. It is easy to fit by guiding the stopper 361A.
[0034]
On the other hand, the outdoor fitting recess 351 also includes a claw portion 352, but this claw portion 352 does not have an inclined surface like the above-described claw portion 342, and is parallel to the indoor / outside surface of the panel body 31. Is formed.
[0035]
As shown in FIG. 6, the mounting member 36 is made of resin, and includes an indoor side mounting member 361 that can lock the inner frame 34 and an outdoor side mounting member 362 that can lock the outer frame 35. .
[0036]
The indoor-side mounting member 361 is fitted to the indoor-side fitting recess 341 and can be locked so that the inner frame 34 and the outer frame 35 do not move away from each other. A stop portion 361A is formed.
[0037]
These indoor side locking portions 361A have an inclined surface 361B that guides the claw portion 342 along the inclined surface 342A of the claw portion 342 of the indoor side fitting concave portion 341, and are slightly deviated from an accurate fitting portion. However, it is formed so as to guide and fit the claw portion 342 of the indoor fitting recess 341.
[0038]
On the other hand, the outdoor mounting member 362 is a chamber that is a fitting locking portion that is fitted to the outdoor fitting recess 351 and can be locked so as not to move in a direction in which the inner frame 34 and the outer frame 35 are separated from each other. An outer locking portion 362A is formed.
The outdoor locking portion 362A has an inclined surface 362B that guides the claw portion 352 of the outdoor fitting recess 351, so that the claw portion 352 of the outdoor fitting recess 351 can be moved even if it is slightly deviated from the accurate fitting portion. It is formed to guide and fit.
[0039]
In FIG. 6, the indoor side mounting member 361 and the outdoor side mounting member 362 are formed to be detachable by sliding in the vertical direction, which is a direction orthogonal to the indoor / outdoor direction. At this time, a support portion 363 for supporting the indoor side attachment member 361 from below is formed at the lower end of the outdoor side attachment member 362. As a result, the indoor mounting member 361 is prevented from being detached downward from the outdoor mounting member 362.
[0040]
As shown in FIG. 2, the integral attachment member 37 is guided by a claw portion 342 of the indoor side fitting concave portion 341 of the inner frame 34 and can be fitted into the indoor side fitting concave portion 341, A fitting locking portion 372 that can be fitted and locked in the outdoor fitting recess 351 of the outer frame 35 is integrally formed.
[0041]
The fitting protrusion 371 is formed of two protrusions that extend in the indoor / outdoor direction, are formed in a substantially plate shape, and are disposed substantially parallel to each other. Since this fitting protrusion 371 does not have a protruding portion like other fitting locking portions 372, it is not locked to the claw portion 342 of the indoor fitting recess 341 and is inserted into the recess 341. Therefore, the fitting protrusion 371 and the indoor-side fitting recess 341 can be attached / detached only by relatively moving each other in the indoor / outdoor direction. On the other hand, the fitting locking portion 372 is formed in the same manner as the above-described outdoor locking portion 362A and is locked to the outdoor fitting recess 351.
[0042]
Further, the multilayer glass 32 is placed on the lower integrated mounting member 37, and the height position of the multilayer glass 32 is adjusted by the height dimension of the integrated mounting member 37.
[0043]
As shown in FIG. 2, a drain groove 315 A is formed over the entire length of the heat insulation board 315 on the upper surface of the heat insulation board (core material) 315 disposed at the lower portion of the opening 31 A. As shown in FIG. 7, the left and right ends of the heat insulation board 315 in which the drainage grooves 315 A are formed are in contact with the flanges 313 and 313 A. A drain hole 312A connected to the outdoor side of 315 is formed.
[0044]
For this reason, as shown by the path of the dashed-dotted arrow 400 in FIGS. 2, 5 and 7, the rainwater that has entered the panel body 31 from between the double-glazed glass 32 and the outer frame 35 is drained by the drainage groove 315A. It is received and passed through the inside of the ridge 313 and the upper part of the lower ridge 312 and is reliably discharged from the drain hole 312A to the outdoor side.
[0045]
Hereinafter, a method of attaching the multilayer glass 32 in the present embodiment to the opening 31A will be described. Since the integrated attachment member 37 is also attached in the same manner as the attachment member 36, the description thereof is omitted here.
As shown in FIG. 8, first, the outdoor-side engaging portion 362 A of the attachment member 36 is fitted and attached in advance to the outdoor-side fitting recess 351 of the outer frame 35.
The outer frame 35 is inserted into the opening 31 A on the outdoor surface side of the panel body 31 and bonded to the panel body 31 using a double-sided tape 51.
[0046]
Next, the multilayer glass 32 is disposed on the outer frame 35 via the airtight member 340, and the inner frame 34 is inserted into the opening 31 A on the indoor surface side of the panel body 31.
At that time, the fitting portion between the indoor side engaging portion 361A and the indoor side fitting recess 341 is not visible because it is on the back side of the inner frame 34, but the slope formed in the claw portion 342 of the indoor side fitting recess 341 The indoor side fitting recess 341 and the indoor side locking portion 361A are guided to an accurate fitting position by the surface 342A and the inclined surface 361B formed in the indoor side locking portion 361A.
[0047]
And as shown in FIG. 4, the indoor side latching | locking part 361A deform | transforms into an inner direction at the time of a fitting, and after fitting, it returns to the original position and is fitted by the spring effect. At this time, as shown in FIG. 8, since L2 is formed to be larger than the distance L1 in FIG. 8, the locking between the indoor side locking portion 361A and the indoor side fitting recess 341 is stronger. It becomes. The fitting strength can be adjusted as appropriate, for example, by adjusting the width L2 between the indoor locking portions 361A with respect to the interval L1 between the claw portions 342 of the indoor fitting recess 341.
Further, an airtight sponge 52 is attached to the inner frame 34, and this airtight sponge 52 is brought into contact with the indoor surface side of the panel body 31 to ensure airtightness.
The multilayer glass 32 is attached to the panel body 31 as described above.
[0048]
Further, for example, when it is desired to replace the multilayer glass 32 due to the damage of the multilayer glass 32 or the like, an elongated jig 4 is inserted between the multilayer glass 32 and the outer frame 35 as shown in FIG. The jig 4 is moved upward to move the indoor mounting member 361 upward, and the indoor mounting member 361 and the outdoor mounting member 362 are removed.
At this time, the indoor-side engaging portion 361A of the indoor-side mounting member 361 slides upward also with respect to the claw portion 342 of the inner frame 34. Therefore, only the indoor side attachment member 361 moves upward by the jig 4.
Similarly, if all the indoor side attachment members 361 are removed, the inner frame 34 is detached from the opening 31A. Next, the broken multilayer glass 32 is removed, a new multilayer glass 32 is attached, the detached indoor side mounting member 361 is attached to the outer frame 35, and the inner frame 34 is attached in the same manner as described above. In this way, the double glazing 32 can be easily replaced.
[0049]
According to this embodiment, the following effects can be obtained.
(1) Since the inclined surface 342A is formed in the claw portion 342 of the indoor fitting recess 341 and the inclined surface 361B is formed in the indoor locking portion 361A of the indoor attachment member 361, the indoor fitting recess 341 and the chamber When fitting the inner locking portion 361A, even if the indoor-side fitting recess 341 and the indoor-side locking portion 361A are slightly deviated from the correct fitting position, they are automatically along the inclined surfaces 342A and 361B. Therefore, even if the indoor-side fitting recess 341 and the indoor-side locking portion 361A cannot be visually recognized, they can be easily fitted.
[0050]
(2) Since the inner frame 34 and the outer frame 35 can be locked in the direction in which the inner frame 34 and the outer frame 35 are separated by the indoor side locking portion 361A and the outdoor side locking portion 362A, the frame 34, 35 can be securely attached. As a result, the multilayer glass 32 can be easily and reliably sandwiched in the opening 31A.
[0051]
(3) Since the attachment member 36 attached by the snap (fitting) method is provided between the inner frame 34 and the outer frame 35 and the inner frame 34 and the outer frame 35 are connected, the inner frame 34 and the outer frame 35 Since it is not necessary to screw the screw, the workability of the assembly work can be improved. In addition, since a cover material for hiding the head of the screw is unnecessary, the number of components can be reduced, and the manufacturing cost and the management cost can be suppressed.
[0052]
(4) When replacing the multi-layer glass 32, each frame 34, 35 is separated without removing the fitting recesses 341, 351 and the locking portions 361A, 362A. Each frame 34, 35 can be easily removed from 31A, and the multilayer glass 32 can be replaced. In addition, since it is not necessary to remove the fitting recesses 341 and 351 and the locking portions 361A and 362A when removing the glass 32, a relatively strong fitting structure can be adopted for the fitting portion. The support strength of the multilayer glass 32 can also be improved.
[0053]
(5) Since the indoor-side mounting member 361 and the outdoor-side mounting member 362 are slidable up and down, for example, if the indoor-side mounting member 361 is moved upward using the elongated jig 4, the indoor-side mounting Since the member 361 and the outdoor attachment member 362 are detached and the inner frame 34 is easily detached from the opening 31A, the multilayer glass 32 can be easily replaced. Moreover, the design property of the heat insulation door 1 can also be improved by changing arbitrarily the multilayer glass 32 to the surface material etc. from which the design property differs according to a use and the objective.
[0054]
(6) Since the support portion 363 is formed on the outdoor side attachment member 362, if the indoor side attachment member 361 is supported from the lower side by the support portion 363, no upward force is applied to the indoor side attachment member 361. As long as the outdoor mounting member 362 is always subjected to gravity in the downward direction and the indoor mounting member 361 and the outdoor mounting member 362 are not detached, the frame 33 can be securely mounted to the opening 31A. Further, since it is not necessary to regulate the movement between the indoor side mounting member 361 and the outdoor side mounting member 362 with the frictional force, the frictional force between the mounting members 361 and 362 can be reduced, and the mounting members 361 and 362 can be made small. It can be easily removed by sliding with force.
[0055]
(7) Since the attachment member 36 is formed of a resin having low thermal conductivity, the inner frame 34 and the outer frame 35 are compared to the case where the metal inner frame 34 and the outer frame 35 are in contact with each other as in the conventional case. Heat conduction between the two can be relatively suppressed. In particular, since the short mounting members 36 are arranged at a predetermined interval and the inner frame 34 and the outer frame 35 are connected, the inner frame 34 and the outer frame 35 are separated from each other via an air layer except for the connected portion. The heat conduction between the inner frame 34 and the outer frame 35 can be further suppressed. Thereby, the heat insulation of the heat insulation door 1 can be improved more.
[0056]
(8) Since the drainage groove 315A is provided on the upper surface of the heat insulating board 315 disposed below the opening 31A, even if rainwater enters between the double-glazed glass 32 and the outer frame 35, the rainwater is drained. It can be received by the groove 315A and discharged from the drain hole 312A to the outside of the panel body 31 via the ridge 313 and the lower ridge 312. For this reason, water leakage to the indoor side can be reliably prevented.
[0057]
In particular, in this embodiment, since the attachment member 36 is formed in a short piece shape and arranged at predetermined intervals, a gap is formed between the frames 34 and 35, but all of this rainwater can be received by the drainage groove 315A. Therefore, water leakage to the indoor surface side can be reliably prevented and drained to the outdoor surface side.
[0058]
(9) Since the water received by the drain groove 315A passes through the trough 313 and reaches the lower trough 312 and can drain from the drain hole 312A formed in the lower trough 312, the water flows along the surface of the panel body 31. Therefore, the cleaning work such as wiping the surface of the panel body 31 can be reduced, and the design and weather resistance of the panel body can be secured.
[0059]
(10) Since the drainage groove 315A is provided on the upper surface of the heat insulating board 315 disposed on the lower side of the opening 31A, for example, the outdoor holding member extruded with a complicated cross-sectional shape as in the prior art is used for drainage. Since the panel body has a relatively simple shape as compared to the case where the holes are provided, the drainage can be easily processed. In addition, since water leakage prevention processing such as sandwiching a sponge between the indoor side holding member and the outdoor side holding member is unnecessary, workability can be improved and the cost is low.
[0060]
(11) Furthermore, since the drainage groove 315A is formed on the upper surface of the heat insulating board 315 as the core material, it is not necessary to separately install a gutter member for forming the drainage groove, and the number of parts can be reduced and the cost can be reduced. As well as improving the assembly workability.
[0061]
Note that the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within a scope in which the object of the present invention can be achieved are included in the present invention.
For example, as shown in FIG. 9, a drain groove 315B as shown by a dotted line in FIG. 9 is formed on the upper surface of the heat insulating board 315 provided below the opening 31A, and the panel body 31 is formed below the drain groove 315B. Two holes 370 may be formed that communicate with the outside. Note that the number of the holes 370 is not limited to two and may be any number. However, the embodiment has advantages that it is easy to process and easy to manufacture.
[0062]
Moreover, in this embodiment, although the drainage groove 315A was formed in the upper surface of the heat insulation board 315 below the opening 31A, the U-shaped shape with the opening side up above the heat insulation board 315 below the opening 31A. The scissors may be arranged so as to contact the left and right scissors 313. If it does in this way, the rigidity of panel body 31 can also be raised.
[0063]
In this embodiment, the inclined surface 342A is formed on the claw portion 342 of the indoor fitting recess 341, and the inclined surface 361B is also formed on the indoor locking portion 361A. However, only the indoor locking portion 361A is inclined. A surface may be formed, that is, an inclined surface may be formed on at least one of the claw portion 342 and the indoor side engaging portion 361A of the indoor side fitting recess 341.
Similarly, on the outdoor side, an inclined surface may be formed on at least one of the claw portion 352 and the outdoor side engaging portion 362A of the outdoor fitting recess 351.
[0064]
Furthermore, an inclined surface should just be formed in at least one of the fitting site | part on the indoor side, and the fitting site | part on the outdoor side. For example, an inclined surface may be formed only on the claw portion 352 of the outdoor fitting recess 351. In this case, the fitting portion on the indoor side is fitted in advance while visually recognizing, and then this inclined surface. It is only necessary that the outdoor fitting recess 351 and the outdoor locking portion 362A are fitted to each other.
[0065]
The shapes of the locking portions 361A and 362A of the mounting members 361 and 362 are not limited to the shapes of the above embodiments. For example, as in the indoor-side locking portion 361A shown in FIG. 10, the protruding portion in contact with the claw portion 342 may be formed obliquely like the inclined surface 361B. With such a shape, the fitting strength between the locking portion 361A and the claw portion 342 can be improved, and it can be prevented from coming off even when a larger wind-resistant pressure is applied.
[0066]
Furthermore, in the present embodiment, the seven attachment members 36 are arranged on the left and right sides of the opening 31A. However, the number of attachment members 36 is not limited to seven, and may be any number as long as the frames can be reliably attached. At that time, the size of the attachment member 36 may be the length over the entire length of the opening 31A. That is, any length may be used as long as it is shorter than the entire length of the opening 31A.
[0067]
In addition, the above-described mounting member 36 may be disposed on the upper and lower sides of the opening 31 A of the panel body 31 instead of the integrated mounting member 37.
[0068]
In this embodiment, although the heat insulation board 315 was used as a core material, the core material without heat insulation may be used, and what is necessary is just to change suitably according to the objective and a use.
Moreover, although the multilayer glass 32 was used as a face material, it is not restricted to this, Arbitrary things may be used if it is face materials, such as a glass and a panel from which design property differs.
[0069]
Further, although the frames 34 and 35 are made of aluminum, they are not limited to this, and may be formed of other materials such as resin. In that case, each frame 34 and 35 is not restricted to what is preliminarily framed, and each frame member may be attached to the panel body 31 separately.
[0070]
Although the mounting member 36 is made of resin, it may be formed of any other material such as a metal material, and in that case, it is particularly preferable that the mounting member 36 is made of a material that is less likely to conduct heat than a metal. In this way, heat conduction between the inner frame 34 and the outer frame 35 can be suppressed.
[0071]
In the present embodiment, the mounting member 36 can be separated by sliding in the vertical direction. However, an L-shape that is continuous from the vertical direction to the indoor / outdoor direction on either the indoor side mounting member 361 or the outdoor side mounting member 362. It is also possible to provide a groove that is shaped like this, and a projection that slides along this groove is provided on the other side so that it can be separated by sliding in the vertical direction and sliding in the indoor and outdoor directions.
Although the support member 363 is provided on the attachment member 36, the support member 363 may not be provided if the frictional force of the sliding portion is increased by processing such as unevenness.
[0072]
In this embodiment, the fitting recesses are provided as the fitting portions on the frames 34 and 35, and the locking portions are provided as the fitting locking portions on the mounting member 36, but the locking portions are provided as the fitting portions on the frames 34 and 35. And a fitting recess may be provided on the mounting member 36 as a fitting locking portion.
Further, the attachment member 36 may not be separated into two as in the present embodiment, but may be an integral type. Even in this case, mounting workability and the like can be improved as compared with conventional screwing.
However, when the integral attachment member 36 is used, the frames 34 and 35 that are the indoor side holding member and the outdoor side holding member and the attachment member 36 must be detached from each other and the frame 34 and 35 must be separated. However, if configured as in the above-described embodiment, there is an advantage that the frames 34 and 35 can be separated without removing this fitting, and the multilayer glass 32 can be easily removed.
[0073]
Further, when the mounting member 36 is composed of an indoor side mounting member 361 and an outdoor side mounting member 362 that can be separated by a slide or the like, the locking portions 361A and 362A and the fitting concave portions 341 and 351 are not always inclined. The surface may not be formed. That is, the mounting members 361 and 362 may be fitted in advance to the frames 34 and 35, and the mounting members 361 and 362 may be connected in this state.
However, if the mounting members 361 and 362 can be separated by sliding or the like, and inclined surfaces are formed in the locking portions 361A and 362A and the fitting recesses 341 and 351, both the mounting operation and the removing operation of the frame 34 are performed. Thus, there is an advantage that both workability at the time of refurbishment such as assembling of the heat insulating door 1 and replacement of the glass 32 can be improved.
[0074]
Further, the structure for preventing water leakage to the indoor side is not limited to the structure in which the drainage groove is formed below the opening 31A as in the above-described embodiment, but has entered from between the multilayer glass 32 and the airtight material 340. A structure may be adopted in which a drainage groove for receiving rainwater is formed integrally with the frame 35 and discharged to the outdoor side through the frame 35.
[0075]
【The invention's effect】
According to the joinery of the present invention, since the inclined portion is formed in at least one of the fitting locking portion and the fitting portion in the indoor side holding member or the outdoor side holding member, the fitting locking portion and the fitting portion are accurate. Even if there is a slight deviation from the proper fitting position, it is automatically corrected to the correct position along the inclined surface of the inclined part, so the fitting part between the fitting locking part and the fitting part cannot be visually recognized. Can be easily fitted.
[0076]
Further, according to the joinery of the present invention, since the indoor side mounting member and the outdoor side mounting member are relatively slidable and detachable, for example, a thin jig or the like between the face material and the indoor side holding member If the indoor side mounting member is moved upwardly while holding the outdoor side mounting member, the indoor side mounting member and the outdoor side mounting member can be removed to easily replace the face material.
[0077]
Furthermore, according to the joinery of the present invention, even if rainwater enters between the face material and the outdoor holding member, the rainwater is discharged to the outside of the panel body by the drainage groove provided at the lower part of the opening. Thus, water leakage to the indoor surface side can be reliably prevented.
