【発明の属する技術分野】
本発明は、出窓に係り、特に施工性の向上及び室外張出側の垂れ下がり修正を可能にした出窓に関する。
【０００２】
【従来の技術】
出窓は、建物の躯体にこれよりも室外側に張出した状態で出窓本体が取付けられるため、この出窓本体の室外張出側が出窓本体の荷重や出窓本体に取付けられる屋根や障子等の荷重により垂れ下がる傾向があり、その垂れ下がりによって障子の建付等に不具合が生じる場合がある。
【０００３】
このような問題を解決するために、窓台に当接される窓台対向部材（水切部材とも言う）と、この窓台対向部材に基部が固定されると共に先端部が出窓本体の下枠（正面下枠）に固定された補強ブラケットとを備えた出窓が提案されるに至っている（特開平１０-８８９１９号公報、特開２００１-２０７７３５号公報参照）。前記補強ブラケットの基部は前記窓台対向部材よりも室内側に突出した後端部を一体または別体で有しており、この後端部材が窓台上に固着具例えばネジで固定されるようになっている。

【発明が解決しようとする課題】
ところで、前記出窓においては、窓台に対する補強ブラケットの固定が重要であり、補強ブラケットが例えば前傾姿勢で固定されると、出窓本体の室外張出側が垂れ下がってしまう問題がある。この問題を防止するためには、屋根や嵌め殺し窓等が組み付けられた出窓本体を建物の躯体の開口に取付ける場合、補強ブラケットが前傾姿勢で固定されることがないように出窓本体を少なくとも２人で持ち上げながら補強ブラケットの基部具体的には後端部を窓台の上面に押しつけ、この状態で補強ブラケットの後端部をもう１人がネジで窓台に固定し、次に、出窓本体の縦枠を躯体にネジで固定するという施工方法が採られている。このため、少なくとも３人の作業員を要し、施工が大変であった。出幅が大きく、重量が１５０Ｋｇ程度あるボウウインド（弓形の出窓）の場合、特に大変であった。
【０００６】
本発明は、前記事情を考慮してなされたもので、室外張出側の垂れ下がりを修正することができると共に施工性の向上が図れる出窓を提供することを目的とする。

【００１３】
【発明の実施の形態】
以下に、本発明の実施の形態を添付図面に基いて詳述する。図１は本発明の実施の形態を示す出窓の概略的縦断面図、図２は同出窓の部分的横断面図、図３は下枠補強ユニットの斜視図、図４は補強ブラケットを示す図で、（ａ）は平面図、（ｂ）は一部断面側面図、図５は同補強ブラケットの斜視図である。
【００１４】
図１ないし図２において、１は出窓で、建物の躯体の開口に取付けられる出窓本体２と、この出窓本体２の上部に設けられる屋根３と、前記開口の窓台４に当接される窓台対向部材５と、この窓台対向部材５及び窓台４に基部が固定され、先端部１１ｘが前記出窓本体２の下枠９の下部に設けられる幅木１０を保持する補強ブラケット１１とを備えている。
【００１５】
図示例の出窓１は、いわゆるボウウインドであり、建物の躯体例えば左右の柱１２に固着具例えばネジ１３で取付固定される左右の縦枠６を有し、両縦枠６間には複数例えば３本の方立７が平面略弓形に配置されている。縦枠６と方立７の上端部間及び方立の上端部間に上枠８が掛け渡され、縦枠と方立の下端部間及び方立の下端部間に下枠９が掛け渡されている。出窓本体２は、これらの複数の枠材６〜９によって組立てられ、組立てられた出窓本体２の正面開口部には嵌め殺し式の障子１４が取付けられ、側面開口部には縦辷り式の障子１５が取付けられている。
【００１６】
前記枠材６〜９及び障子１５の框材は例えば金属形材例えばアルミニウム合金の押出形材からなり、各金属形材の室内露出部には合成樹脂製の形材が取付けられ、室内外の断熱性の向上が図られている。下枠９下部の見栄えを良くするために、下枠９の下部には平面略弓形に設けられた幅木１０がネジ１６で取付けられている。出窓本体２の上部には天板１７や屋根３が設けられ、出窓本体２の下部にはテーブル板１８や底板１９が設けられている。また、左右の縦枠６の上端部間には天板見切り縁２０が掛け渡されている。
【００１７】
前記窓台対向部材５は、本実施例では図３に示すように平面弓形の幅木１０の両端部間に掛け渡されてリベット２１で固定されている。この窓台対向部材５は例えばアルミニウム合金の押出形材からなり、横長の板状に形成されている。この窓台対向部材５は、前記窓台４の上面に係止される窓台係止片部２２と、室外側下部横片部２３と、上縁部にテーブル板１８の下面との間をシールする気密材２４を取付けるための気密材取付溝部２５とを有している。主として前記窓台対向部材５、補強ブラケット１１及び幅木１０により出窓本体２の下枠部分を補強する下枠補強ユニット２６が構成されている。２７は、縦枠６を受けるクッション材である。
【００１８】
前記補強ブラケット１１は、断面逆Ｕ字状に形成された剛性を有する金属材からなり、その基部が窓台対向部材５の室外面に鍔部２８を介して当接されてリベット２９で固着されている。窓台対向部材５の上縁部には補強ブラケット１１が室内外に貫通し得る切欠部３０が設けられ、補強ブラケット１１の基部詳しくは後端部１１ｃが窓台対向部材５よりも室内側に突出されており、その後端部１１ｃ下面が鍔部３１を介して前記窓台係止片部２２上にリベット３２で固着されている。また、後端部１１ｃ下面には窓台４上に当接されてネジ３３で固定される鍔部３４も形成されている。
【００１９】
補強ブラケット１１の本数は、出窓の幅により決定され、図示例では窓台対向部材５の中央部に１本であるが、２本或いは３本以上複数本であってもよい。前記幅木１０には内周に溝部３５が設けられ、前記補強ブラケット１１の先端部１１ｘは幅木１０の溝部３５に差込まれ、リベット３６で固定されている。このように構成された下枠補強ユニット２６の幅木１０の上部に出窓本体２の下枠９がネジ１０で固定されて、出窓本体２と下枠補強ユニット２６が一体化されている。
【００２０】
前記下枠９、すなわち正面下枠及び側面下枠には、これらで区画された形状のテーブル板１８の室外側周縁部を差込んで保持するテーブル板保持溝部３７が形成され、テーブル板１８の室外側周縁部がそのテーブル板保持溝部３７に差込まれてネジ３８で固定されている。テーブル板１８は、出窓本体２を躯体に取付けた後、室内側から補強ブラケット１１の上面に沿ってスライドさせることにより前記テーブル板保持溝部３７に差込まれ、簡単にセットできる。
【００２１】
また、補強ブラケット１１を一体的に有する窓台対向部材５により下枠部分の強度の向上が図れると共に、テーブル板保持溝部３７、補強ブラケット１１及び窓台対向部材５の上縁部により格子状に複数に区画されて略同一平面とされた上面部にテーブル板１８を載置するようにして、テーブル板１８の支持強度の向上を図っているため、テーブル板１８を強度メンバーとする必要がなく、従ってテーブル板１８の薄型化が図れると共にテーブル板１８を必要以上に強固に固定する必要がない。また、テーブル板１８の室内側後端部を固定するために、補強ブラケット１１の後端部１１ｃには引掛部３９が水平に突出形成され、テーブル板１８にはその引掛部３９に係合する係合溝部４０が形成されており、これによりテーブル板１８の持上がりが防止されている。
【００２２】
一方、前記補強ブラケット１１は、図４ないし図５に示すように、前記窓台対向部材５よりも室外側が前後すなわち前端部材１１ａと基部材１１ｂに二分割されていると共に、基部材１１ｃに対して前端部材１１ａをジャッキアップするためのジャッキ機構４１が設けられている。具体的には、基部材１１ｂに前端部材１１ａが上下動自在に支持されると共に、前端部材１１ａまたは基部材１１ｂ、図示例では基部材１１ｂには前端部材１１ａをジャッキアップするためのジャッキ機構４１を構成するねじ部材（例えばボルト）４２が設けられている。
【００２３】
更に具体的には、前記前端部材１１ａは、その後端部が基部材１１ｂ内に挿入し得るように基部材１１ｂの内幅よりも若干小さい外幅に形成され、その後端部が基部材１１ｂに水平の支軸４３を介して垂直回動自在に支持されている。この場合、前端部材１１ａが基部材１１ｂよりも上方へ回動し得るように前端部材１１ａの後端部の上縁部には基部材１１ｂの上面部との干渉を避けるための切欠部４４が設けられている。前記ねじ部材４２は基部材１１ｂの上面部の前端側に設けた孔部４５から挿入され、前記前端部材１１ａの後端部側の両側部間に水平に掛け渡された横材（例えば軸軸）４６に垂直に設けられたネジ穴４７に螺合されている。
【００２４】
ねじ部材４２の頭部４２ａは基部材１１ｂの上面部に係止されている。このねじ部材４２の頭部４２ａには回転工具である例えば六角レンチを係合させるための係合凹部４８が設けられ、これによりねじ部材４２を回転し得るようになっている。なお、前端部材１１ａ及び基部材１１ｂ（後端部１１ｃを含む）の上面部には長手方向に沿って溝４９が設けられ、この溝４９内に前記ねじ部材４２の頭部４２ａが収容されていることが好ましい。ねじ部材４２を緩めると前端部材１１ａが支軸４３を支点に下降し、ねじ部材４２を締めると前端部材１１ａが支軸４３を支点に上昇しジャッキアップされる。基部材１１ｂの側面にはジャッキアップ量を示す目盛５０が付されている。
【００２５】
次に、以上の構成からなる出窓の作用を述べる。屋根３や嵌め殺し式の障子１４等が組み付けられた出窓本体２を建物の躯体の開口に取付ける場合には、先ず、予め補強ブラケット１１のジャッキ機構４１のねじ部材４２を弛めて前端部材１１ａを下げておき、出窓本体２を２人で持ち上げて窓台対向部材５の窓台係止片部２２及び補強ブラケット１１の後端部１１ｃを窓台４の上面に載せたなら、出窓本体２を室外側から１人で支える。この場合、補強ブラケット１１の前端部材１１ａが下がっているため、補強ブラケット１１の基部具体的には後端部１１ｃを窓台４の上面に容易に且つぴたりと着けることができる。
【００２６】
この状態で、他の１人が出窓本体２の縦枠６を建物の柱１２にネジ１３で固定し、次に、補強ブラケット１１の後端部１１ｃをネジ３３，５１で窓台４に固定する。すなわち、出窓本体２の室外張出側が垂れ下がっていたとしても、補強ブラケット１１の前端部材１１ａが下がっているため、労力を要せずに容易に補強ブラケット１１の後端部１１ｃを窓台４の上面にぴたりと着けることができ、このため、ネジ止めによる固定作業を容易に行うことができ、作業性ないし施工性の向上が図れる。
【００２７】
次に、前記補強ブラケット１１の前端部材１１ａをジャッキ機構４１のねじ部材４２を締め付けることによりジャッキアップして高さを調整し、これにより出窓本体の室外張出側の垂れ下がりを矯正ないし修正する。この場合の目安は、補強ブラケット１１の前端部材１１ａの上面部が基部材１１ｂの上面部とフラットになるように前端部材１１ａの高さを調整すればよい。なお、基部材１１ｂの側面の目盛５０を見たり、或いは前端部材１１ａの上面に水準器をあてて補強ブラケット１１の前端部材１１ａの高さを調整してもよい。なお、補強ブラケット１１が若干前方へ傾斜した状態で窓台４上に固定されてしまい、補強ブラケット１１の前端部材１１ａを水平にジャッキアップしても出窓本体２の室外張出側が垂れ下がりが十分に修正されなかった場合には、更にねじ部材４２を締め付けて前端部材１１ａを水平よりもやや上方にジャッキアップするようにしてもよい。
【００２８】
このようにして出窓本体２の室外張出側の垂れ下がりを修正したなら、テーブル板１８を室内側から補強ブラケット１１の上面に沿って室外側へスライドさせ、テーブル板保持溝部３７に差込むと共に、テーブル板１８の後端部の係合溝部４０を補強ブラケット１１後端の引掛部３９に係合させ、テーブル板１８の前縁部をネジ３８で固定すればよい。
【００２９】
このように前記出窓１によれば、建物の躯体の開口に取付けられる出窓本体２と、該出窓本体２の上部に設けられる屋根３と、前記開口の窓台４に当接される窓台対向部材５と、該窓台対向部材５及び窓台４に基部が固定され、先端部１１ｘが前記出窓本体２の下枠９下部に設けられる幅木１０を保持する補強ブラケット１１とを備え、前記補強ブラケット１１を前端部材１１ａと基部材１１ｂに分割すると共に基部材１１ｂに対して前端部材１１ａをジャッキアップするためのジャッキ機構４１を設けているため、室外張出側の垂れ下がりを修正することができると共に施工性の向上が図れる。前述したように出窓の取付作業を２人の作業員で容易に行うことができ、労力の軽減及び施工性の向上が図れ、特に重量のあるボウウインドに好適である。
【００３０】
図６は補強ブラケットの変形例を示す斜視図、図７は同補強ブラケットを示す図で、（ａ）は平面図、（ｂ）は一部断面側面図である。本実施例において、前記実施例と同一部分は同一符号を付して説明を省略する。本実施例では、ジャッキ機構４１がカム部材５２により構成されている。すなわち、補強ブラケット１１が前端部材１１ａと基部材１１ｂに分割され、基部材１１ｂに対して前端部材１１ａが上下動自在に支持されると共に、前端部材１１ａをジャッキアップするためのカム部材５２が設けられている。
【００３１】
具体的には、前端部材１１ａの後端部が基部材１１ｂ内にその前端から挿入されると共に水平の支軸４３を介して上端側が垂直回動自在に支持され、基部材１１ｂの対向内側面には前記支軸４３の下方に左右一対のカム部材５２が水平の軸５３を介して回動自在に設けられている。このカム部材４２は漸次半径が増大するカム面５２ａを有する偏心カムからなっている。
【００３２】
前端部材１１ａの後端部には、両カム部材５２のカム面５２ａに当接する当接部５４が設けられている。また、カム部材５２の最少半径部と最大半径部の境界部には、前記当接部５４の上端部または下端部に係合してカム部材５２の回動を規制するためのストッパー部５５が形成されている。前記カム部材５２が固定された軸５３の両端部は、基部材１１ｂの両側部に回動自在に支持され、軸５３の両端部または一端部にはスパナを係合させて回動操作（調節）するための係合頭部５３ａが設けられている。カム部材５２をカム面５２ａの半径が増大する方向に回動すると、前端部材１１ａが上方にジャッキアップされ（上昇し）、逆にカム部材５２をカム面５２ａの半径が減少する方向に回動すると、前端部材１１ａが下降するようになっている。このように構成された補強ブラケット１１においても、前記実施例と同様の効果が得られる。
【００３３】
以上、本発明の実施の形態ないし実施例を図面により詳述してきたが、本発明は前記実施の形態ないし実施例に限定されるものではなく、本発明の要旨を逸脱しない範囲での種々の設計変更等が可能である。例えば、実施例では下枠の下部に幅木が設けられた出窓が例示されているが、出窓としては前記幅木を備えていないものであっても良く、その場合、補強ブラケットの先端部が下枠を保持するようになっている。また、実施例では補強ブラケット１１が基部に後端部１１ｃを一体に有する場合が示されているが、補強ブラケット１１は基部に後端部１１ｃを一体または別体で有していればよい。後端部１１ｃが別体の場合は、後端部１１ｃが窓台対向部材５の室内面にリベット等で固着されている。本発明は、窓台対向部材を備えていない出窓にも適用することが可能である。
【００３４】

[Problems to be solved by the invention]
By the way, in the bay window, it is important to fix the reinforcing bracket to the window base. When the reinforcing bracket is fixed, for example, in a forward inclined posture, there is a problem that the outdoor projecting side of the bay window body hangs down. In order to prevent this problem, when attaching a bay window main body with a roof, a slashing window, etc., to the opening of the building frame, at least the bay window main body is prevented so that the reinforcing bracket is not fixed in a forward tilted posture. While lifting by two people, press the base of the reinforcing bracket, specifically the rear end against the top of the window base, and in this state, the other end fixes the rear end of the reinforcing bracket to the window base with a screw. A construction method is adopted in which the vertical frame of the main body is fixed to the housing with screws. For this reason, at least three workers were required, and the construction was difficult. In the case of a bow window (bow-shaped bay window) having a large protruding width and a weight of about 150 kg, it was particularly difficult.
