ところで、前記出窓においては、金属製の室外形材に対して樹脂製の室内形材が着脱可能に取付けられていて、室内形材が損傷した場合等に室内形材が交換可能になっていると便利である。しかしながら、前記縦枠の室内形材の場合、縦枠の上端部間に掛け渡されている天板見切り縁によって室内形材が拘束されているため、室内形材を取外すことが困難であるという問題がある。
【０００５】
本発明は、前記事情を考慮してなされたもので、上端部間に天板見切り縁が掛け渡された縦枠を構成する樹脂製の室内形材を金属製の室外形材から容易に取外すことができるようにした出窓を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明は、建物の躯体の開口に位置されて躯体に取付けられる左右の縦枠を含む出窓本体と、該出窓本体の上部に天板を介して設けられる屋根と、前記左右の縦枠の上端部間に掛け渡されて前記天板の室内端部を覆う天板見切り縁とを備え、前記開口には上額縁と縦額縁とが取付けられ、前記縦枠は金属製の室外形材に樹脂製の室内形材を着脱可能に取付けてなり、前記天板見切り縁は本体部と、該本体部の両端に配されて前記縦枠の室内形材に支持される支持部とからなり、前記本体部は垂直壁部と、該垂直壁部の一側面の上側から水平に延出されて前記天板の下面を受ける上片部と、前記垂直壁部の他側面の下端から水平に延出されて前記上額縁の下面を受ける下片部と、前記支持部の基部を支持すべく前記垂直壁部の他側面に形成された断面Ｌ字状のリブとを有し、前記支持部の基部には前記上片部の上面に載る固定片部が形成され、該固定片部が前記上片部に対して下方から固着具で着脱可能に連結されていることを特徴とする。
【０００７】
【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は出窓本体を内側から見た部分的斜視図、図４は天板見切り縁の端部の支持部を示す斜視図、図５は天板見切り縁の端部が支持部を介して縦枠の樹脂製室内形材に支持される構造を概略的に示す図で、（ａ）は平面図、（ｂ）は（ａ）のＢ−Ｂ矢視図、（ｃ）は（ａ）のＣ−Ｃ矢視図である。
【０００８】
図１〜図３に示すように、出窓１は、建物の躯体の開口に位置されて躯体例えば柱１２に固着具例えばネジ１３で取付けられる左右の縦枠６を含む出窓本体２を備えている。出窓本体２は、室外側に突出させて例えば平面台形状に形成されている。出窓本体２は、左右の縦枠６と、両縦枠６よりも屋外側に配置される左右の方立７と、縦枠６と方立７の上端部間、下端部間に配置される側面上枠８ａ、側面下枠９ａと、左右の方立７の上端部間、下端部間に配置される正面上枠８、正面下枠９とを有し、これらをネジ止めにより枠状に組立てて構成されている。組立てられた出窓本体２の正面開口部には嵌め殺し窓のガラスパネル１４が取付けられ、側面開口部には開き窓の障子５０が取付けられている。
【０００９】
前記出窓本体２を構成する縦枠等の枠材及び障子５０の框材は金属製例えばアルミニウム合金製の室外形材と、各室外形材の室内露出部を覆うべく設けられた合成樹脂製の室内形材とから構成されており、室内外の断熱性の向上が図られている。前記枠材にあっては、例えば損傷等で室内形材の交換が可能なように室外形材に対して室内形材が着脱可能に取付けられている。例えば、縦枠６は、図５（ａ）に示すように、室外形材６ｘに対して室内形材６ｙが側面部の窓（例えば開き窓）と平行な矢印Ｆ方向に嵌合し、矢印Ｆとは逆方向に離脱し得る嵌合部２５と、ネジ２６とにより出窓内空間内において着脱可能に取付けられている。
【００１０】
左右の縦枠６の下端部間には、前記開口の窓台４に当接される窓台対向部材（水切り部材ともいう）５が掛け渡されてネジで固定されており、この窓台対向部材５には正面下枠９及び側面下枠９ａからなる下枠部分を補強する補強ブラケット１１が設けられている。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を取付けるための気密材取付溝部２４とを有している。前記補強ブラケット１１は、例えば断面逆Ｕ字状に形成された剛性を有する金属材からなる。補強ブラケット１１は、出窓の幅に応じて適宜本数設けられている。
【００１１】
正面下枠９の内側部には溝幅の大きい上部溝部３５ａと、溝幅の狭い下部溝部３５ｂとが設けられ、その上部溝部３５ａには前記補強ブラケット１１の先端部１１ｘが挿入されてネジ５１で固定されている。下部溝部３５ｂには後述の底板１９の前縁部が挿入嵌合されている。底板１９の後縁部は前記窓台対向部材５の室外側下部横片部２３に支持固定されている。
【００１２】
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。下枠すなわち正面下枠９及び側面下枠９ａ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に差込まれてネジで固定されている。テーブル板１８は、出窓本体２を躯体１２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。
【００１３】
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。
【００１４】
前記出窓本体２の下部における窓台対向部材５と下枠（正面下枠及び側面下枠）で区画された領域には図示しない断熱材が設けられ、該領域を下方から覆うべく前記底板１９が設けられている。
【００１５】
一方、出窓本体２の上部には天板１７を介して屋根３が設けられている。左右の縦枠６の上端部間には前記天板１７の室内端部を覆う（覆い隠す）天板見切り縁２０が掛け渡されている。建物の開口には、上部の上額縁２７と左右の縦額縁２８とが取付けられる。前記天板見切り縁２０は、上額縁２７の室外端部も覆う（覆い隠す）ようになっている。天板見切り縁２０は、例えばアルミニウム合金の押出形材からなり、横長の長尺に形成されている。天板１７は、天板見切り縁２０を含む出窓本体２の上部に載置され、上枠（正面上枠９、側面上枠９ａ）や天板見切り縁２０に室内から（この場合、下方から）ネジ２９，３０で固定されている。
【００１６】
前記天板見切り縁２０は、図４ないし図５に示すように、本体部２０ａと、この本体部２０ａの両端に配されて前記縦枠６の室内形材６ｙに支持される支持部３１とからなり、支持部３１が本体部２０ａに室内（出窓内空間内、図示例では下方）から固着具例えばネジ３２で着脱可能に連結されている。前記本体部２０ａは、垂直壁部４１と、この垂直壁部４１の一側面の上側から水平に延出されて天板１７の下面を受ける上片部４２と、垂直壁部４１の他側面の下端から水平に延出されて上額縁２７の下面を受ける下片部４３を有している（図４参照）。上片部４２及び下片部４３は、いずれも先端縁部が上向きに折曲されている。また、垂直壁部４１の他側面には断面Ｌ字状のリブ４４が形成されている。
【００１７】
前記縦枠６の室内形材６ｙの室内端部には、縦額縁２８の縁部にネジ止めされる取付フィン部４５と、一対のリブ４６，４７からなる上下方向に連続した係合溝４８とが形成されている。前記取付フィン部４５の上端部には、図３ないし図５（ｂ）に示すように、上額縁２７との干渉を避けるための切欠部４９が設けられている。
【００１８】
前記天板見切り縁２０の本体部２０ａの長さは、左右の縦枠６の室内形材６ｙ間の幅と略同じであり、本体部２０ａの端部から支持部３１が延出されている。支持部３１は剛性を有する金属板からなり、正面略Ｌ字状に形成され、先端部３１ａが下向きに突出されている。支持部３１の基部３１ｂは、前記本体部２０ａの垂直壁部４１に沿ってリブ４４に支持されている。また、支持部３１の基部３１ｂには、上片部４２の上面に載る固定片部３１ｃが曲げ加工により形成されている。この固定片部３１ｃと干渉しないように前記垂直片部４１の上縁部が切欠されている。前記上片部４２に対して固定片部３１ｃが下方からネジ３２で着脱可能に取付固定されている。上片部４２にはネジ３２を下方から挿通する孔部（図示省略）が設けられ、固定片部３１ｃにはネジ３２を螺合する雌ねじ部３１ｄが設けられている。
【００１９】
前記本体部２０ａの端部から前記支持部３１が前記室内形材６ｙの取付フィン部４５の切欠部４９を通って延出され、下向きに突出した支持部３１の先端部３１ａが前記係合溝４８に上方から差込まれて係合支持されている。なお、前記支持部３１にはＬ字状に隆起した補強部５３がプレス加工により設けられていることが好ましい。
【００２０】
以上の構成からなる出窓１においては、縦枠６の樹脂製室内形材６ｙを交換すべく取外す場合には、先ず天板見切り縁２０の本体部２０ａの端部に支持部３１を固定しているネジ３２を下方からねじ回しで緩めて取外し、天板見切り縁２０の本体部２０ａと支持部３１の連結を解除する。次に、天板見切り縁２０の本体部２０ａを天板１７や上額縁２７に固定しているネジ３０，３３を取外して天板見切り縁２０の本体部２０ａを取外す。次に、前記樹脂製室内形材６ｙを固定しているネジ２６，３４を取外し、室内形材を矢印Ｆ方向にスライドさせて縦枠６の金属製室外形材６ｘから離脱させて取外せば良い。前記室内形材６ｙは、天板見切り縁２０の本体部２０ａと支持部３１の連結を解除することにより天板見切り縁２０による拘束が解かれているため、縦枠６の室外形材６ｘから容易に取外すことができ、室内形材６ｙの交換作業を容易に行うことができる。
【００２１】
このように前記出窓１によれば、建物の躯体に取付けられる左右の縦枠６を含む出窓本体２と、該出窓本体２の上部に天板１７を介して設けられる屋根３と、前記左右の縦枠６の上端部間に掛け渡されて前記天板１７の室内端部を覆う天板見切り縁２０とを備え、前記縦枠６は金属製の室外形材６ｘに樹脂製の室内形材６ｙを着脱可能に取付けてなり、前記天板見切り縁２０は本体部２０ａと、該本体部２０ａの両端に配されて前記縦枠６の室内形材６ｙに支持される支持部３１とからなり、該支持部３１が本体部２０ａに室内から固着具例えばネジ３２で着脱可能に連結されているため、前記天板見切り縁２０の本体部２０ａと支持部３１の連結を解除することにより天板見切り縁２０による拘束を解くことができ、上端部間に天板見切り縁２０が掛け渡された縦枠６を構成する樹脂製の室内形材６ｙを金属製の室外形材６ｘから容易に取外すことが可能となる。
【００２２】
また、前記縦枠６の室内形材６ｙが室外形材６ｘに対して、側面部の窓例えば開き窓と平行な矢印Ｆ方向に嵌合し、矢印Ｙとは逆方向に離脱し得る嵌合部２５と、ネジ２６とにより着脱可能に取付けられているため、出窓本体２を分解したり、屋根３を取外したりすることなく室内形材６ｙを確実に且つ容易に取外すことができる。
【００２３】
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。
【００２４】
【発明の効果】
以上要するに本発明によれば、下方から前記固着具による前記天板見切り縁の本体部と支持部の基部との連結を容易に解除することができ、上端部間に天板見切り縁が掛け渡された縦枠を構成する樹脂製の室内形材を金属製の室外形材から容易に取外すことができる。
