Description

【０００１】
【発明の属する技術分野】
本発明は、出窓に係り、特に地板の取付けや取外しが容易な出窓に関する。
【０００２】
【背景技術】
出窓は、手軽に室内のスペースを確保（広く）したり、室外の意匠のアクセントになるために広く普及している。この出窓は、例えば、平面台形の出窓を例に説明すると、通常は、建物躯体（建物の壁開口に設けられた柱等）に取り付けられる縦枠と、この縦枠から離れて配置される方立（縦枠）との間に袖上枠および袖下枠を連結して袖窓部（袖ユニット）を組み立て、この袖窓部の各方立間に正面上枠および正面下枠を連結材（ジョイント部材）を用いて接合して正面窓部（正面枠ユニット）を組み立てていた。
そして、この袖ユニットおよび正面枠ユニットからなる出窓ユニット内に、ガラス等の各種面材を嵌め殺し状態に組み込んだり、引違い障子や縦辷り出し窓用の障子等を組み込んで出窓を構成していた。
【０００３】
このような出窓の下部には、地板が配置される。この地板の室外側の外周縁はは、袖下枠および正面下枠で保持される。一方、地板の室内側端縁は、建物開口部内まで延長配置される場合もあるが、特開２００１−９０４３７号公報に開示されているように、建物の窓台の屋外端に配置される場合もある。
すなわち、窓台に水切り材を兼用する支持材を取り付けておき、地板を組み付けた出窓ユニットを建物の開口部に取り付け、前記地板の室内側端縁を支持材で保持していた。つまり、地板は、その外周縁が各下枠および支持材の保持溝に差し込まれ、各下枠や支持材で挟持することで保持されていた。
【０００４】
【発明が解決しようとする課題】
ところで、このような出窓ユニットは、地板を出窓ユニットに組み込んでから吊り上げて建物開口に取り付けていた。このため、その施工作業中や出窓ユニットを取り付けた後の仕上げ作業中などに地板を傷つけてしまい、地板の交換が必要となる場合がある。
しかしながら、従来の出窓では、各下枠および支持材で地板を挟持していたため、地板の外側面は下枠や支持材に密着していた。このため、出窓ユニットが建物に取り付けられた状態では地板を下枠、支持材の保持溝から外すことができず、出窓ユニットを建物から取り外さなければ地板を交換することができない。このため、地板が傷ついた場合には、その交換作業が非常に困難であるという問題があった。
【０００５】
また、出窓の施工にあたっては、まず出窓ユニットに地板を取り付けた後、出窓ユニットを建物開口部に取り付けなければならず、施工手順が限定されるために、施工作業の自由度が低くなり、作業性が低下するという問題もあった。
【０００６】
本発明の目的は、出窓ユニットを建物に取り付けた後でも地板の交換を容易に行えるとともに、施工手順の自由度を高めることができて作業性を向上することができる出窓を提供することにある。
【０００７】
【課題を解決するための手段】
本発明は、建物の壁面開口に取り付けられる出窓であって、複数本の縦枠、この縦枠間に掛け渡された上枠および下枠を備える出窓本体と、出窓本体の下枠および建物壁面に取り付けられた支持材間に架け渡された地板とを有し、前記地板の室外側端縁は前記下枠に形成された保持溝内に挿入可能とされ、前記地板の室内側端縁は前記支持材本体から室外側に突設された載置部上に載置可能とされ、かつ地板の室内側端縁と支持材本体との間には所定寸法の隙間が形成され、前記隙間の寸法は、この隙間を利用して地板を室内側にスライド移動させた際に、前記室外側端縁が下枠の保持溝から外れて地板が着脱可能な寸法に設定され、前記地板の室内側端縁と前記支持枠本体との隙間部分は、前記地板および支持枠本体にまたがって配置されるカバー材で被覆され、前記カバー材の室内側端縁は、前記支持材本体の端縁に係合するとともに、当該カバー材には、前記隙間内に挿入されて前記支持材の係合爪にその弾性力で係合される係合部が一体に形成されていることを特徴とするものである。
【０００８】
本発明では、地板の室内外方向の寸法を、出窓本体と支持材本体との室内外方向の寸法よりも短くすることで、地板の室内側端縁と支持材本体との間に所定寸法の隙間を設定する。そして、この隙間を利用して地板を室内側に移動することで地板の室外側端縁を下枠の保持溝から外す。地板の室内側端縁は支持材の載置部上に載置されているので、室外側端縁が保持溝から外れれば、地板を上方に移動して取り外すことができる。一方、逆の手順を行えば地板を出窓本体に取り付けることができる。
このように地板の室内側端縁と支持材本体との間に所定寸法の隙間を設けることだけで、建物壁面に取り付けられた出窓本体から地板を容易に着脱できる。従って、地板が破損した場合でも、低コストでかつ短時間で交換することができる。また、地板は出窓本体を建物躯体に取り付けた後からでも取り付けることができるので、地板を出窓本体に組み込んでからでなければ建物に取り付けることができなかった従来例に比べて出窓の施工手順の自由度が高まり、施工作業性も向上できる。
【０００９】
本発明は、建物の壁面開口に取り付けられる出窓であって、複数本の縦枠と、この縦枠間に掛け渡された上枠および下枠とを備える出窓本体と、出窓本体の下枠および建物壁面に取り付けられた支持材間に架け渡された地板とを有し、前記出窓本体は、少なくとも２つの袖窓部を備え、前記地板の室外側端縁は前記下枠に形成された保持溝内に挿入可能とされ、前記地板の室内側端縁は前記支持材本体から室外側に突設された載置部上に載置可能とされ、かつ地板の室内側端縁と支持材本体との間には所定寸法の隙間が形成され、前記隙間の寸法は、この隙間を利用して地板を室内側にスライド移動させ、かつ室内外方向に直交する出窓の幅方向にスライド移動させた際に、前記一方の袖窓部の下枠保持溝に保持される室外側端縁以外の室外側端縁が下枠の保持溝から外れて地板が着脱可能な寸法に設定され、前記地板の室内側端縁と前記支持枠本体との隙間部分は、前記地板および支持枠本体にまたがって配置されるカバー材で被覆され、前記カバー材の室内側端縁は、前記支持材本体の端縁に係合するとともに、当該カバー材には、前記隙間内に挿入されて前記支持材の係合爪にその弾性力で係合される係合部が一体に形成されていることを特徴とするものである。
【００１０】
本発明は、地板を前記隙間の寸法分、室内側にスライド移動させ、かつ室内外方向に直交する出窓の幅方向にスライド移動させた際に、前記一方の袖窓部の下枠保持溝に保持される室外側端縁以外の室外側端縁が下枠の保持溝から外れて地板が着脱可能に設けられている。
すなわち、地板の室内側端縁と支持材本体との間に設定された所定寸法の隙間を利用し、地板を室内側にスライド移動することで、例えば、２つの袖窓部間に設けられた正面窓部の下枠保持溝から地板が外れ、地板の室内側端縁およびこの室内側端縁に対向する室外側端縁は上方に移動可能となる。
さらに、地板を出窓の幅方向にスライド移動することで、２つの袖窓部の一方の袖窓部の下枠保持溝から地板が外れる。従って、一方の袖窓部から外れた地板の室外側端縁を上方に持ち上げて斜め上方に地板を移動すれば、他方の袖窓部の下枠保持溝からも地板が外れる。つまり、いわゆるけんどん方式で地板を取り外すことができる。一方、逆の手順を行えば地板を出窓本体に取り付けることができる。
このように地板の室内側端縁と支持材本体との間に所定寸法の隙間を設け、地板を２方向にスライド移動させることだけで、建物壁面に取り付けられた出窓本体から地板を容易に着脱できる。従って、地板が破損した場合でも、低コストでかつ短時間で交換することができ、地板の施工順序に制限が無いため、出窓の施工手順の自由度が高まり、施工作業性も向上できる。
【００１１】
本発明は、建物の壁面開口に取り付けられる出窓であって、出窓本体と、出窓本体および建物壁面に取り付けられた支持材間に架け渡された地板とを有し、前記出窓本体は、建物の壁面から室外側に突出した２つの袖窓部と、これらの袖窓部の室外側端縁間に配置された正面窓部とを備え、前記各袖窓部は、各袖窓部の室内側端縁間の間隔寸法が各袖窓部の室外側端縁間の間隔寸法よりも大きくされ、前記地板の室外側端縁は前記正面窓部および袖窓部の各下枠に形成された保持溝内に挿入可能とされ、前記地板の室内側端縁は前記支持材本体から室外側に突設された載置部上に載置可能とされ、かつ地板の室内側端縁と支持材本体との間には所定寸法の隙間が形成され、地板を前記隙間を利用して室内側にスライド移動させた際に、前記室外側端縁が正面窓部および袖窓部の各下枠の保持溝から外れて地板が着脱可能に設けられ、前記地板の室内側端縁と前記支持枠本体との隙間部分は、前記地板および支持枠本体にまたがって配置されるカバー材で被覆され、前記カバー材の室内側端縁は、前記支持材本体の端縁に係合するとともに、当該カバー材には、前記隙間内に挿入されて前記支持材の係合爪にその弾性力で係合される係合部が一体に形成されていることを特徴とするものである。
【００１２】
本発明では、平面台形状の出窓のように、袖窓部の室内側端縁間寸法つまり出窓の室内側開口幅寸法が、袖窓部の室外側端縁間寸法つまり正面窓部の幅寸法よりも大きくされている。このため、地板の室内側端縁と支持材本体との間に設定された所定寸法の隙間を利用して地板を室内側に移動すると、地板の袖窓部側の室外側端縁（袖窓側端縁）と袖窓部の下枠保持溝との隙間寸法は移動に伴い徐々に大きくなる。
従って、前記隙間を利用した室内側への移動寸法と、地板の袖窓側端縁の保持溝内への挿入寸法（呑込寸法）を適切に設定すれば、地板を室内側にスライド移動させるだけで、地板の袖窓側端縁および正面窓側端縁（正面窓側の室外側端縁）を各保持溝から外すことができる。これにより、地板を上方に移動して取り外すことができる。一方、逆の手順を行えば地板を出窓本体に取り付けることができる。
このため、建物壁面に取り付けられた出窓本体から地板を容易に着脱でき、地板が破損した場合でも、低コストでかつ短時間で交換することができるとともに、地板の施工順序の制限が無くなって出窓の施工手順の自由度が高まり、施工作業性も向上できる。
【００１３】
本発明は、建物の壁面開口に取り付けられる出窓であって、出窓本体と、出窓本体および建物壁面に取り付けられた支持材間に架け渡された地板とを有し、前記出窓本体は、建物の壁面から室外側に突出した２つの袖窓部と、これらの袖窓部の室外側端縁間に配置された正面窓部とを備え、前記地板の室外側端縁は前記正面窓部および袖窓部の各下枠に形成された保持溝内に挿入可能とされ、前記地板の室内側端縁は前記支持材本体から室外側に突設された載置部上に載置可能とされ、かつ地板の室内側端縁と支持材本体との間には所定寸法の隙間が形成され、地板を前記隙間を利用して室内側にスライド移動させ、かつ室内外方向に直交する出窓の幅方向にスライド移動させた際に、前記一方の袖窓部の下枠保持溝に保持される室外側端縁以外の室外側端縁が下枠の保持溝から外れて地板が着脱可能に設けられ、前記地板の室内側端縁と前記支持枠本体との隙間部分は、前記地板および支持枠本体にまたがって配置されるカバー材で被覆され、前記カバー材の室内側端縁は、前記支持材本体の端縁に係合するとともに、当該カバー材には、前記隙間内に挿入されて前記支持材の係合爪にその弾性力で係合される係合部が一体に形成されていることを特徴とするものである。
【００１４】
本発明では、地板の室内側端縁と支持材本体との間に設定された所定寸法の隙間を利用して地板を室内側にスライド移動することで、地板の正面窓側端縁が保持溝から外れる。また、地板を出窓幅方向にスライド移動することで、２つの袖窓部の一方の袖窓部の下枠保持溝から地板が外れる。従って、一方の袖窓部から外れた地板の室外側端縁を上方に持ち上げて斜め上方に地板を移動すれば、他方の袖窓部の下枠保持溝からも地板が外れる。つまり、いわゆるけんどん方式で地板を取り外すことができる。一方、逆の手順を行えば地板を出窓本体に取り付けることができる。
このように地板の室内側端縁と支持材本体との間に所定寸法の隙間を設け、地板を２方向にスライド移動させることだけで、建物壁面に取り付けられた出窓本体から地板を容易に着脱できる。従って、地板が破損した場合でも、低コストでかつ短時間で交換することができ、地板の施工順序に制限が無いため、出窓の施工手順の自由度が高まり、施工作業性も向上できる。その上、平面台形状の出窓だけでなく、平面矩形状の角形出窓等の様々な平面形状の出窓でも適用でき、適用できる出窓種類も多くできる。
【００１５】
なお、請求項２および請求項４の発明では、地板を出窓の幅方向にスライド移動させるために、各袖窓部の保持溝と地板の袖窓側端縁間に予め所定の隙間を設定しておけばよい。また、台形出窓のように、地板を室内側にスライド移動させることで地板の袖窓側端縁と保持溝との間に所定寸法の隙間を形成できる場合には、その隙間を利用して地板を出窓幅方向にスライド移動させてもよい。
【００１６】
以上において、前記地板の室内側端縁と前記支持枠本体との隙間部分は、前記地板および支持枠本体にまたがって配置されるカバー材で被覆されているので、隙間が室内側に露出せず、意匠性を向上できる。
【００１９】
【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。なお、各図面においては図面を見やすくするために、断面を示すハッチングを基本的に省略して記載している。
図１は出窓１の縦断面図、図２は出窓１の横断面図、図３は出窓１の内観斜視図である。
出窓１は、建物１００の壁面開口１０１に取り付けられている。建物１００の壁面開口１０１は、左右に配置された一対の柱１０２と、この柱１０２間に掛け渡されたまぐさ１０３および窓台１０４によって区画形成されている。本実施形態では、柱間に内壁が配置されて室内側に柱１０２が露出し、和室に用いられることが多い真壁納まりとされている。但し、本発明は大壁納まりでも適用可能である。
まぐさ１０３および窓台１０４は、和室用の障子１０５を建て付けるための鴨居および敷居として用いられている。
【００２０】
出窓１は、平面形態（横断面形状）が台形とされた台形出窓であり、室外側に突出した左右両側の袖窓部５と、これら袖窓部５の間に設けられた正面窓部６とを有する出窓本体２で構成されている。
この出窓本体２の上部には、天板５４および屋根５５が取り付けられ、出窓本体２の下部には地板６０および底板５０が取り付けられている。
【００２１】
出窓本体２は、柱１０２にネジ等で固定される左右一対の縦枠１１と、この縦枠１１に対して間隔を空けて立設された左右一対の縦枠としての方立１２と、縦枠１１および方立１２の上端部間および下端部間にそれぞれ架け渡された袖上枠１３および袖下枠１４と、両方立１２の上端部間および下端部間にそれぞれ架け渡された正面上枠３１および正面下枠３２とからなる出窓フレーム３を備えている。
本実施形態では、出窓フレーム３は、まず、前記縦枠１１、方立１２、袖上枠１３、袖下枠１４を四角枠状に組み合わせて袖枠ユニットを構成し、この袖枠ユニットの方立１２間に前記正面上枠３１および正面下枠３２をネジや連結材などで固定することで構成されている。この際、方立１２および正面上枠３１、正面下枠３２により正面枠ユニットが構成される。従って、本実施形態では、袖枠ユニットの方立１２は、正面枠ユニットの縦枠として兼用されていることになる。
【００２２】
袖枠ユニットにはガラス面材１７が嵌め込まれてＦＩＸ窓を構成している。このＦＩＸ窓部分によって前記袖窓部５が構成されている。なお、建物１００の壁面に対する袖窓部５の傾斜角度θ１は、本実施形態では約４５度とされているが、６０度などでもよく、その角度は限定されない。そして、出窓１は台形出窓であるため、袖窓部５の室内側端縁間寸法Ｗ１つまり出窓１の室内側開口幅寸法Ｗ１が、袖窓部５の室外側端縁間寸法Ｗ２つまり正面窓部６の幅寸法Ｗ２よりも大きくされている。
正面枠ユニットには、室内外の２枚の障子３５が組み込まれて引違い窓を構成しており、この引違い窓部分によって前記正面窓部６が構成されている。
なお、各枠の材質は限定されないが、例えばアルミニウム合金の押出形材などが利用できる。
【００２３】
前記地板６０は、略台形板状に形成され、出窓本体２の下枠である袖下枠１４、正面下枠３２と、建物壁面、具体的には窓台１０４の室外面に取り付けられた水切り材を兼用する支持材７０によって支持されている。
具体的には、各下枠１４，３２には、地板６０の室外側端縁、具体的には正面窓側端縁６１と袖窓側端縁６２とが差し込まれる保持溝６５が形成されている。各保持溝６５は、図４に拡大して示すように、断面略Ｌ字状の下片６６と、平面板状の上片６７と、これらの各片６６，６７を連結する溝底面部６８とで断面略コ字状に形成されている。ここで、下片６６はＬ字状に形成されているので、下片６６と溝底面部６８との間には空間が確保される。この空間により、地板６０を保持溝６５内に対し、斜め下方に向かって挿入することができる。
【００２４】
一方、支持材７０は、図５にも示すように、窓台１０４や壁材にビス止めされる支持材本体７１と、この支持材本体７１から室外側に突設されて前記地板６０が載置される載置部７２と、底板５０の端縁を保持する底板保持部７３とを備え、窓台１０４の全長に渡って設けられている。この支持材７０は、合成樹脂材が用いられることもあるが、通常はアルミニウム合金等の金属材で構成されている。
【００２５】
そして、地板６０を下枠１４，３２や支持材７０に取り付けた際に、地板６０の室内側端縁６３の端面と前記支持材本体７１の室外面との間には、寸法Ｌ１の隙間８０が形成されるように設定されている。
この隙間８０は、合成樹脂製あるいは金属製のカバー材９０で被覆されている。このカバー材９０は、地板６０の室内側端縁６３から支持材本体７１に跨って配置され、その室内側端縁は前記支持材本体７１の端縁に係合するように構成されている。
カバー材９０には、さらに、前記隙間８０内に挿入されて支持材７０の係合爪にその弾性力で係合される係合部９１も一体に形成されている。
【００２６】
一方、地板６０を下枠１４，３２や支持材７０に取り付けた際に、地板６０の袖窓側端縁６２の端面と前記下枠１４の保持溝６５における溝底面部６８との間には、図４に示すように、寸法Ｌ２の隙間が形成されるように設定されている。さらに、地板６０を前記隙間８０の寸法分、室内側にスライドさせた場合には、下枠１４の保持溝６５や地板６０の袖窓側端縁６２が室内外方向つまり地板６０のスライド方向に対して斜めに形成されているので、図４に一点鎖線で示すように、地板６０の各袖窓側端縁６２と溝底面部６８との各隙間は、寸法Ｌ２よりも大きな寸法Ｌ３となる。ここで、寸法Ｌ３は、上片６７の奥行き寸法Ｌ４に対し、Ｌ４／２＜Ｌ３＜Ｌ４となるように設定され、地板６０を出窓の幅方向にスライド移動し、地板６０の一方の袖窓側端縁６２を溝底面部６８に当接させた場合に、地板６０の他方の袖窓側端縁６２は保持溝６５から外れるように設定されている。
【００２７】
なお、互いに隣接する各下枠１４，３２の上片６７間の接続部分は、コーナーピース５２で被覆されている。このコーナーピース５２には、地板６０の正面窓側端縁６１が当接する位置決め用ストッパ５２Ａも設けられている。
【００２８】
このような地板６０は、出窓本体２を建物の躯体に取り付けた後、以下の手順で取り付けられる。
まず、図３に示すように、地板６０は、地板６０の一方の袖窓側端縁６２を一方の下枠１４の保持溝６５に差し込んだ後、他方の袖窓側端縁６２を他方の下枠１４の保持溝６５に差し込むことで、つまり、いわゆるけんどん方式で取り付けられる。
さらに、この際、地板６０は、室内側端縁６３が前記支持材７０側に寄って正面窓側端縁６１が正面下枠３２の保持溝６５から外れた位置になければならない。従って、各袖窓側端縁６２が保持溝６５内に保持されてから、地板６０を室外側にスライド移動する。地板６０の正面窓側端縁６１が保持溝６５内に設けられた位置決め用のストッパ５２Ａに当接すると、地板６０の室内側端縁６３と支持材本体７１との隙間８０の寸法がＬ１になる。
この状態で地板６０をネジを用いて下枠１４，３２に固定し、前記カバー材９０を隙間８０に挿入して固定する。
なお、ネジの固定は、例えば、正面下枠３２の上片６７から地板６０の正面窓側端縁６１にネジを螺合したり、逆に下片６６側から正面窓側端縁６１にネジを螺合すればよい。袖窓側端縁６２は必要に応じてねじ止めすればよい。
【００２９】
一方、出窓１の施工後に、地板６０を取り外すには、前記取付手順と逆に、カバー材９０およびネジを取り外し、地板６０を寸法Ｌ１分室内側に移動してその正面窓側端縁６１を保持溝６５から外し、さらに、地板６０を左右いずれかに移動して一方の袖窓側端縁６２を保持溝６５から外す。その後、けんどん方式で地板６０を取り外せばよい。
なお、室内外方向の移動と左右方向の移動とを一度に行えるように、図６に示すように、地板６０を水平面内で斜め方向（室内外方向つまり見込み方向と左右方向つまり出窓幅方向の両方向に対して斜めとなる方向）に移動してもよい。
【００３０】
このような本実施形態によれば、次のような効果がある。
(1) 建物躯体に取り付けられた出窓本体２に対して地板６０を着脱することができる。このため、施工途中や完成後に地板６０が破損した場合でも、従来のように出窓本体２を取り外して地板６０を交換する必要が無く、地板６０を容易に交換でき、交換のための費用も軽減することができる。
【００３１】
(2) 出窓本体２を建物躯体に取り付けた後でも、地板６０を取り付けることができるので、従来のように出窓本体に地板を組み込んでから建物躯体に取り付けなければならない場合に比べて、地板６０の取付順序を自由に設定でき、出窓１の施工作業性を向上することができる。その上、地板６０の破損は、地板が組み込まれた出窓本体を建物躯体に取り付ける際に発生することが多いが、本実施形態では、出窓本体２を建物躯体に取り付けた後に地板６０を取り付けることができるので、地板６０の破損を効果的に防止でき、地板６０の交換作業も不要にでき、施工コストも低減できる。
【００３２】
(3) 地板６０の室内側端縁６３と支持材本体７１との間に隙間８０を設け、この隙間８０を利用して地板６０を着脱できるように構成したので、地板６０を着脱するための構造も簡単にでき、コストの増加も抑えることができる。
なお、隙間８０を塞ぐためにカバー材９０を設けているが、断熱性能を確保するために水切り材の室内露出面を合成樹脂製のカバー材で被覆することは従来から行われていたため、カバー材９０を設けた場合でも従来に比べてコスト的には殆ど変わらないため、コスト増も効果的に抑えることができる。
【００３３】
(4) 出窓１は台形出窓であって、袖窓部の室内側端縁間の寸法Ｗ１が室外側端縁間（正面窓部）の寸法Ｗ２よりも大きくなっているので、地板６０を室内側にスライド移動させた際に、地板６０の袖窓側端縁６２と保持溝６５の溝底面部６８との間隔は広がることになる。従って、地板６０はその固定状態では、室外側端縁６１，６２の保持溝６５内に挿入された部分の寸法を比較的大きくできて、確実に保持溝６５で保持できるとともに、地板６０を室内側にスライド移動させた場合には、室外側端縁６１，６２の保持溝６５内に挿入された部分の寸法を小さくできて、左右方向に移動することでけんどん方式で確実に保持溝６５から取り外すことができる。すなわち、非常に簡単な構造でありながら、固定状態では地板６０を保持溝６５で確実に保持でき、かつ着脱する際には保持溝６５に対して地板６０を容易に着脱することができ、施工作業性に優れた出窓１にすることができる。
【００３４】
(5) カバー材９０を合成樹脂製にすれば、支持材７０が金属製の場合に外気で冷却されても、その支持材７０が室内側に露出することを樹脂製のカバー材９０で防ぐことができるので、結露発生を抑えることができ、断熱性能も向上できる。一方、カバー材９０を金属製にすれば、地板６０の室内側端縁６３の保持強度を向上できる。
【００３５】
なお、本発明は、前記実施形態に限定されるものではない。
例えば、前記実施形態の出窓１は、平面台形状であったが、本発明の出窓としては、図７に示すように、左右の袖窓部５と、正面窓部６とが直交配置された平面矩形状の角形出窓１Ａであってもよい。この出窓１Ａでは、平面形状が略矩形状の地板６０Ａが用いられる。
この出窓１Ａにおいても、地板６０Ａを室内側方向および出窓幅方向の移動つまり図７の矢印で示す斜め方向に移動すれば、地板６０Ａの正面窓側端縁６１と、袖窓側端縁６２の一方とを保持溝から外すことができ、けんどん方式で地板６０Ａを着脱することができる。
【００３６】
さらに、前記実施形態では、室内外方向と出窓幅方向の２方向に地板６０をスライド移動させて、地板６０を着脱していたが、図８に示すように、室内外方向の移動のみで地板６０を着脱してもよい。
すなわち、平面台形や三角形、多角形の出窓のように、袖窓部５の室内側端縁間寸法Ｗ１つまり出窓１の室内側開口幅寸法Ｗ１が、袖窓部５の室外側端縁間寸法Ｗ２つまり正面窓部６の幅寸法Ｗ２よりも大きくされていれば、地板６０を室内側に移動するだけで、地板６０の袖窓側端縁６２と保持溝との隙間は移動に伴い徐々に大きくなる。
従って、前記地板６０の袖窓側端縁６２の保持溝内への挿入寸法と、地板６０の移動寸法（隙間８０の寸法Ｌ１）とを適切に設定し、地板６０を室内側にスライド移動させるだけで、地板６０の各室外側端縁６１，６２を保持溝から外し、地板６０を着脱できるようにしてもよい。
この場合、前記実施形態と同じ作用効果が得られる上、地板６０の移動方向が１方向のみでよいため、着脱作業をより一層簡単に行うことができる。
【００３７】
さらに、前記実施形態では、隙間８０を形成し、地板６０をスライド移動させることで地板６０を着脱できるように構成していたが、図９に示すように、保持溝６５を、下片部６６Ａおよびこの下片部６６Ａに対して爪部の係合等によって着脱可能な上片部６７Ａで構成し、上片部６７Ａを取り外すことで、地板６０を水平方向にスライド移動させずに着脱できるようにしてもよい。
この際、各下枠１４，３２の各保持溝６５部分を、図９に示す上片部６７Ａを着脱する構造で構成してもよいし、袖下枠１４の保持溝６５のみあるいは正面下枠３２の保持溝６５のみを図９の構造としてもよい。なお、各下枠１４，３２の一方のみを上片部６７Ａ、下片部６６Ａで構成した場合、他方はスライド移動やけんどん方式等で保持溝から室外側端縁６１，６２を外せばよい。
【００３８】
さらに、出窓としては、平面台形や矩形状のものに、三角形状、五角形状、六角形状等の様々な平面形状の出窓でもよい。三角形状の出窓は、一対の袖窓部のみで構成されるものである。五角形状や六角形状の出窓は、袖窓部５間に複数（五角形状では２つ、６角形状では３つ）の互いに所定角度で傾斜配置された正面窓部６を備えたものである。
【００３９】
前記実施形態では、袖窓部５をＦＩＸ窓とし、正面窓部６を引違い窓としていたが、この窓構成は限定されず、袖窓部５を縦辷り出し窓等の開閉窓とし、正面窓部６をＦＩＸ窓等にしてもよく、これらは適宜設定すればよい。
さらに、正面窓部６には、障子３５および網戸を設けていたが、装飾格子、面格子などを組み込んでもよい。また、網戸は特に設けなくてもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a bay window, and more particularly to a bay window in which a ground plate can be easily attached and detached.
[0002]
[Background]
The bay windows are widely used to easily secure (widen) indoor spaces and to accentuate outdoor designs. For example, a flat trapezoidal bay window will be described as an example of this bay window. Normally, a vertical frame attached to a building frame (such as a pillar provided in a wall opening of a building) and a person arranged away from the vertical frame. A sleeve window part (sleeve unit) is assembled by connecting the sleeve upper frame and sleeve lower frame to the vertical (vertical frame), and the front upper frame and front lower frame are connected to each side of the sleeve window part. The front window part (front frame unit) was assembled by joining using (joint member).
And, in the bay window unit consisting of the sleeve unit and the front frame unit, various face materials such as glass are fitted and assembled, or the sliding window and the sliding window for the vertical sliding window are incorporated to constitute the bay window. It was.
[0003]
A bottom plate is disposed under the bay window. The outer peripheral edge on the outdoor side of the base plate is held by a sleeve lower frame and a front lower frame. On the other hand, the indoor side edge of the main plate may be extended to the inside of the building opening, but as disclosed in Japanese Patent Application Laid-Open No. 2001-90437, it is arranged at the outdoor end of the building window stand. There is also.
That is, a supporting material that also serves as a draining material is attached to the window base, a bay window unit that is assembled with a base plate is attached to the opening of the building, and the indoor side edge of the base plate is held by the supporting material. That is, the outer peripheral edge of the main plate is inserted into the holding grooves of the lower frames and the support material, and is held by being sandwiched between the lower frames and the support material.
[0004]
[Problems to be solved by the invention]
By the way, in such a bay window unit, the ground plane was assembled in the bay window unit and then lifted and attached to the building opening. For this reason, the ground plate may be damaged during the construction work or during the finishing work after the bay window unit is attached, and the ground plate may need to be replaced.
However, in the conventional bay window, since the ground plane is sandwiched between the lower frames and the support material, the outer surface of the ground plane is in close contact with the lower frame and the support material. For this reason, when the bay window unit is attached to the building, the ground plane cannot be removed from the lower frame and the holding groove of the support material, and the ground plane cannot be replaced unless the bay window unit is removed from the building. For this reason, when the main plate is damaged, there is a problem that the replacement work is very difficult.
[0005]
In addition, when installing the bay window, first the ground plate must be attached to the bay window unit, and then the bay window unit must be attached to the opening of the building. There was also a problem that the performance decreased.
[0006]
An object of the present invention is to provide a bay window that can easily replace the ground plane even after the bay window unit is attached to a building, and can improve the workability by increasing the degree of freedom of the construction procedure. .
[0007]
[Means for Solving the Problems]
The present invention is a bay window attached to a wall opening of a building, and includes a plurality of vertical frames, a bay window body including an upper frame and a lower frame spanned between the vertical frames, a lower frame of the bay window body, and a building wall surface A base plate spanned between support members attached to the base plate, and an outdoor side edge of the base plate can be inserted into a holding groove formed in the lower frame, and an indoor side edge of the base plate is It is possible to place it on a placing part protruding from the support body to the outdoor side, and a gap of a predetermined dimension is formed between the indoor side edge of the main plate and the support body, and the gap The dimensions are set such that when the base plate is slid to the indoor side using this gap, the outside edge of the outdoor side is removed from the holding groove of the lower frame and the base plate can be attached and detached. The gap between the indoor side edge of the base plate and the support frame main body is covered with a cover material disposed across the base plate and the support frame main body, and the indoor side edge of the cover material is the support material The cover member is integrally formed with an engaging portion that is inserted into the gap and is engaged with the engaging claw of the support member with its elastic force. It is characterized by that.

In the present invention, the dimension of the baseboard in the indoor / outdoor direction is made shorter than the dimension of the bay window body and the support material body in the indoor / outdoor direction. Set the gap. And the outdoor side edge of a ground plane is removed from the holding groove of a lower frame by moving a ground plane to the indoor side using this clearance gap. Since the indoor side edge of the main plate is mounted on the mounting portion of the support material, the base plate can be moved upward and removed if the outdoor side edge is removed from the holding groove. On the other hand, if the reverse procedure is performed, the main plate can be attached to the bay window body.
In this way, the ground plane can be easily attached to and detached from the bay window body attached to the building wall surface by merely providing a gap of a predetermined dimension between the indoor side edge of the ground plane and the support material body. Therefore, even if the ground plane is damaged, it can be replaced at a low cost and in a short time. In addition, since the main plate can be attached even after the bay window body has been attached to the building frame, the construction procedure of the bay window can be compared to the conventional example, which could only be installed in the building after the main plate was installed in the bay window body. The degree of freedom increases and the workability of construction can be improved.
[0009]

A wall surface opening 101 of the building 100 is defined by a pair of pillars 102 arranged on the left and right sides, and a lintel 103 and a window stand 104 spanned between the pillars 102. In the present embodiment, the inner wall is arranged between the pillars, the pillar 102 is exposed on the indoor side, and the wall is often used in a Japanese-style room. However, the present invention can also be applied to a large wall.
The lintel 103 and the window sill 104 are used as a duck and a sill for laying a shoji 105 for a Japanese-style room.
[0020]
The bay window 1 is a trapezoidal bay window having a trapezoidal plane shape (cross-sectional shape). The left and right sleeve window portions 5 projecting to the outdoor side, and the front window portion 6 provided between the sleeve window portions 5. It is comprised by the bay window main body 2 which has these.
A top plate 54 and a roof 55 are attached to the upper portion of the bay window body 2, and a ground plate 60 and a bottom plate 50 are attached to the lower portion of the bay window body 2.
[0021]
The bay window body 2 includes a pair of left and right vertical frames 11 fixed to a pillar 102 with screws or the like, a vertical frame 12 as a pair of left and right vertical frames standing with a space from the vertical frame 11, and a vertical The upper sleeve 13 and the lower sleeve 14 spanned between the upper end and the lower end of the frame 11 and the stand 12, respectively, and the front spanned between the upper and lower ends of both the stand 12 respectively. A bay window frame 3 including a frame 31 and a front lower frame 32 is provided.
In this embodiment, the bay window frame 3 first forms a sleeve frame unit by combining the vertical frame 11, the vertical 12, the sleeve upper frame 13, and the sleeve lower frame 14 into a square frame shape. The front upper frame 31 and the front lower frame 32 are fixed between the uprights 12 with screws or connecting materials. At this time, the vertical frame 12, the front upper frame 31, and the front lower frame 32 constitute a front frame unit. Therefore, in this embodiment, the stand 12 of the sleeve frame unit is also used as the vertical frame of the front frame unit.
[0022]
A glass face material 17 is fitted into the sleeve frame unit to constitute a FIX window. The sleeve window portion 5 is constituted by the FIX window portion. The inclination angle θ1 of the sleeve window 5 with respect to the wall surface of the building 100 is about 45 degrees in the present embodiment, but may be 60 degrees or the like, and the angle is not limited. Since the bay window 1 is a trapezoidal bay window, the indoor side edge dimension W1 of the sleeve window portion 5, that is, the indoor side opening width dimension W1 of the bay window 1 is equal to the outdoor side edge dimension W2 of the sleeve window portion 5, that is, the front window. It is made larger than the width dimension W2 of the part 6.
The front frame unit incorporates two sliding doors 35 inside and outside to form a sliding window. The sliding window portion constitutes the front window 6.
In addition, although the material of each frame is not limited, for example, an extruded shape of an aluminum alloy can be used.
[0023]
The base plate 60 is formed in a substantially trapezoidal plate shape, and a draining frame attached to a sleeve lower frame 14 and a front lower frame 32 which are lower frames of the bay window body 2 and a building wall, specifically, an outdoor surface of the window base 104. It is supported by a support material 70 that also serves as a material.
Specifically, each lower frame 14, 32 is formed with a holding groove 65 into which the outdoor side edge of the main plate 60, specifically, the front window side edge 61 and the sleeve window side edge 62 is inserted. As shown in an enlarged view in FIG. 4, each holding groove 65 includes a lower piece 66 having a substantially L-shaped cross section, an upper piece 67 having a planar plate shape, and a groove bottom surface portion 68 that connects these pieces 66 and 67. And is formed in a substantially U-shaped cross section. Here, since the lower piece 66 is formed in an L shape, a space is secured between the lower piece 66 and the groove bottom surface portion 68. With this space, the main plate 60 can be inserted obliquely downward into the holding groove 65.
[0024]
On the other hand, as shown in FIG. 5, the support member 70 includes a support member main body 71 screwed to the window base 104 and the wall member, and projects from the support member main body 71 to the outdoor side so that the base plate 60 is mounted thereon. A mounting portion 72 to be placed and a bottom plate holding portion 73 for holding the edge of the bottom plate 50 are provided, and are provided over the entire length of the window base 104. The support material 70 is made of a metal material such as an aluminum alloy, although a synthetic resin material may be used.
[0025]
When the base plate 60 is attached to the lower frames 14 and 32 and the support member 70, a gap 80 having a dimension L <b> 1 is provided between the end surface of the indoor side edge 63 of the base plate 60 and the outdoor surface of the support member main body 71. Is set to be formed.
The gap 80 is covered with a cover material 90 made of synthetic resin or metal. The cover member 90 is disposed so as to extend from the indoor side edge 63 of the main plate 60 to the support material body 71, and the indoor side edge is configured to engage with the edge of the support material body 71.
The cover member 90 is also integrally formed with an engaging portion 91 that is inserted into the gap 80 and engaged with the engaging claw of the support member 70 by its elastic force.
[0026]
On the other hand, when the base plate 60 is attached to the lower frames 14 and 32 and the support member 70, between the end surface of the sleeve window side edge 62 of the base plate 60 and the groove bottom surface portion 68 in the holding groove 65 of the lower frame 14, As shown in FIG. 4, it is set so that a gap of dimension L2 is formed. Further, when the base plate 60 is slid to the indoor side by the size of the gap 80, the holding groove 65 of the lower frame 14 and the sleeve window side edge 62 of the base plate 60 are in the indoor outdoor direction, that is, the sliding direction of the base plate 60. Therefore, as shown by the one-dot chain line in FIG. 4, each gap between each sleeve window side edge 62 of the base plate 60 and the groove bottom surface portion 68 has a dimension L3 larger than the dimension L2. Here, the dimension L3 is set so that L4 / 2 <L3 <L4 with respect to the depth dimension L4 of the upper piece 67, the base plate 60 is slid in the width direction of the bay window, and one sleeve window side of the base plate 60 is When the end edge 62 is brought into contact with the groove bottom surface portion 68, the other sleeve window side end edge 62 of the base plate 60 is set so as to be disengaged from the holding groove 65.
[0027]
The connecting portion between the upper pieces 67 of the lower frames 14 and 32 adjacent to each other is covered with the corner piece 52. The corner piece 52 is also provided with a positioning stopper 52A with which the front window side edge 61 of the main plate 60 abuts.
[0028]
Such a ground plane 60 is attached in the following procedure after attaching the bay window body 2 to the building frame.
First, as shown in FIG. 3, the base plate 60 has one sleeve window side end edge 62 of the base plate 60 inserted into the holding groove 65 of one lower frame 14, and the other sleeve window side end edge 62 is then connected to the other lower frame. 14 is inserted into the holding groove 65, that is, it is attached by a so-called kendon system.
Further, at this time, the base plate 60 must be in a position where the indoor side edge 63 is close to the support material 70 side and the front window side edge 61 is out of the holding groove 65 of the front lower frame 32. Therefore, after each sleeve window side edge 62 is held in the holding groove 65, the base plate 60 is slid to the outdoor side. When the front window side edge 61 of the main plate 60 comes into contact with a positioning stopper 52A provided in the holding groove 65, the dimension of the gap 80 between the indoor side end 63 of the main plate 60 and the support material main body 71 becomes L1. .
In this state, the base plate 60 is fixed to the lower frames 14 and 32 using screws, and the cover material 90 is inserted into the gap 80 and fixed.
The screws can be fixed by, for example, screwing screws from the upper piece 67 of the front lower frame 32 to the front window side edge 61 of the main plate 60, or conversely, screws from the lower piece 66 side to the front window side edge 61. You just need to match. The sleeve window side edge 62 may be screwed as necessary.
[0029]
On the other hand, in order to remove the base plate 60 after the construction of the bay window 1, the cover material 90 and screws are removed, and the base plate 60 is moved to the indoor side by the dimension L 1, and the front window side edge 61 is held in the holding groove. Then, the base plate 60 is moved to the left or right to remove one sleeve window side edge 62 from the holding groove 65. Thereafter, the base plate 60 may be removed by a tendon method.
As shown in FIG. 6, the ground plane 60 is inclined in the horizontal plane (in the indoor / outdoor direction, that is, the prospective direction and in the left / right direction, that is, the bay window width direction) so that the movement in the indoor / outdoor direction and the movement in the left / right direction can be performed at a time. You may move to the direction which becomes diagonal with respect to both directions.
[0030]
According to this embodiment, there are the following effects.
(1) The main plate 60 can be attached to and detached from the bay window body 2 attached to the building frame. For this reason, even if the ground plane 60 is damaged during the construction or after completion, there is no need to remove the bay window body 2 and replace the ground plane 60 as in the conventional case, the ground plane 60 can be easily replaced, and the cost for replacement is reduced. can do.
[0031]
(2) Since the main plate 60 can be attached even after the bay window body 2 is attached to the building frame, the main plate 60 is compared with the case where the main plate is incorporated into the bay window main body and must be attached to the building frame as in the prior art. Can be freely set, and the workability of the bay window 1 can be improved. In addition, damage to the ground plane 60 often occurs when the bay window body incorporating the ground plane is attached to the building frame. In this embodiment, the ground plane 60 is attached after the bay window body 2 is mounted to the building frame. Therefore, it is possible to effectively prevent the main plate 60 from being damaged, to eliminate the need to replace the main plate 60, and to reduce the construction cost.
[0032]
(3) Since the gap 80 is provided between the indoor side edge 63 of the ground plane 60 and the support material main body 71 and the ground plane 60 can be attached and detached using the gap 80, the ground plane 60 can be attached and detached. The structure can be simplified and the increase in cost can be suppressed.
In addition, although the cover material 90 is provided in order to close the clearance gap 80, since covering the indoor exposure surface of the draining material with the synthetic resin cover material was conventionally performed in order to ensure heat insulation performance, the cover material Even when 90 is provided, the cost is hardly changed as compared with the conventional case, so that an increase in cost can be effectively suppressed.
[0033]
(4) The bay window 1 is a trapezoidal bay window, and the dimension W1 between the indoor side edges of the sleeve window is larger than the dimension W2 between the outdoor side edges (front window part). When sliding inward, the gap between the sleeve window side edge 62 of the base plate 60 and the groove bottom surface portion 68 of the holding groove 65 is widened. Accordingly, in the fixed state of the base plate 60, the dimensions of the portions inserted into the holding grooves 65 of the outdoor side edges 61 and 62 can be made relatively large so that the base plate 60 can be securely held by the holding grooves 65 and the base plate 60 can be held in the chamber. When the sliding movement is made inward, the dimension of the portion inserted into the holding groove 65 of the outer edge 61, 62 can be reduced, and the holding groove 65 can be surely secured in a steadily manner by moving in the left-right direction. Can be removed from. That is, although the structure is very simple, the ground plane 60 can be securely held by the holding groove 65 in the fixed state, and the ground plane 60 can be easily attached to and detached from the holding groove 65 when being attached and detached. The bay window 1 having excellent workability can be obtained.
[0034]
(5) If the cover member 90 is made of synthetic resin, the cover member 90 made of resin prevents the support member 70 from being exposed to the indoor side even if the support member 70 is made of metal and is cooled by outside air. Therefore, the occurrence of condensation can be suppressed and the heat insulation performance can be improved. On the other hand, if the cover member 90 is made of metal, the holding strength of the indoor side edge 63 of the main plate 60 can be improved.

Furthermore, in the said embodiment, although it comprised so that the clearance gap 80 was formed and the ground plane 60 could be attached or detached by sliding the ground plane 60, as shown in FIG. 9, the holding groove 65 is made into the lower piece part 66A. The upper piece 67A can be attached to and detached from the lower piece 66A by engaging the claw, and the upper piece 67A is removed so that the main plate 60 can be attached and detached without sliding in the horizontal direction. It may be.
At this time, each holding groove 65 portion of each of the lower frames 14 and 32 may have a structure in which the upper piece portion 67A shown in FIG. 9 is attached or detached, or only the holding groove 65 of the sleeve lower frame 14 or the front lower frame. Only the 32 holding grooves 65 may have the structure of FIG. When only one of the lower frames 14 and 32 is constituted by the upper piece portion 67A and the lower piece portion 66A, the outer edge 61 and 62 may be removed from the holding groove by the slide movement or the noodle method.
[0038]
Further, the exit window may be an exit window having various planar shapes such as a triangular shape, a pentagonal shape, a hexagonal shape, etc., as well as a flat trapezoidal or rectangular shape. The triangular bay window is composed of only a pair of sleeve window portions. The pentagonal or hexagonal bay window includes a plurality of front window portions 6 (two in the case of a pentagon and three in the case of a hexagon) that are inclined and arranged at a predetermined angle between the sleeve windows 5.
[0039]
In the above-described embodiment, the sleeve window portion 5 is a FIX window and the front window portion 6 is a sliding window. However, this window configuration is not limited, and the sleeve window portion 5 is an opening / closing window such as a vertical window, and the front surface. The window 6 may be a FIX window or the like, and these may be set as appropriate.
Furthermore, although the front window 6 is provided with the shoji 35 and the screen, a decorative lattice, a surface lattice, or the like may be incorporated. Moreover, the screen door does not need to be provided.
Moreover, the structure of the bay window main body 2, a material, etc. are not restricted to the said embodiment. For example, each frame 13, 14, 31, 32 is not limited to one made of an extruded aluminum material, but may be made of another non-ferrous metal or a metal material such as stainless steel. Insulating frame material with reduced heat conduction from the outdoor surface to the indoor surface by placing a heat insulating material with lower thermal conductivity than the aluminum material such as synthetic resin and synthetic wood between the outdoor surface and the indoor surface of the frame You may utilize what comprised.
