Description

【０００１】
【発明の属する技術分野】
本発明は、ベランダやテラスに好適に用いられる開口部装置、及び該開口部装置において、異なる厚さの床材に同一サッシ下枠を兼用する方法に関する。
【０００２】
【従来の技術】
室内側からベランダやテラスに出入りすることが可能な開口部装置において、床材の厚さは採用される施工方法により異なるものである。例えば在来工法では、床材の典型的な厚さは４０ｍｍである。一方、最近建設数の多い２×４（ツーバイフォー）工法では２７ｍｍとされている。サッシ下枠の厚さは通常決められたものである。一方、床材の端部と、下枠との隙間からは雨水等が侵入しやすく、これを許すと床材が早期に劣化して望ましくない。
【０００３】
例えば、図８に示す在来工法の場合、床材８１の厚さは４０ｍｍと決まっているので、下枠８２の高さはこれに合わせて、床材８１上面の室外側と下枠８２の上面とを覆うカバー部材８３を両者の上面に配置して、ねじ釘８４により固定している。このようにして、床材８１の室内側端部と下枠８２の室内側端部との隙間から雨水等が侵入して、内部で床材８１（主として木材で形成されることが多い。）が劣化するのを防止している。
【０００４】
また、床材の厚さが変化する場合、サッシ下枠の形状を一定の高さにするとサッシ下枠と、床材との間には段差が生じる。特に床材の高さが下枠より高い場合、床材の木口が露出する。さまざまな厚さの床材に対応し、上記露出する木口や、施工上必然的に生じる該木口と下枠との隙間を隠蔽するために床材の室外側端面に断面「Ｌ」字状のアングル材が使用されている。このように異なる厚さの床材に一定の高さの下枠を兼用しようとする場合、下枠の高さは通常最も使用頻度の高い床材厚さ、すなわち上記した２×４（ツーバイフォー）工法の床材厚さ２７ｍｍに合わせて設定される。図９（ｂ）は、床材の厚さが２７ｍｍの場合を示すものである。床材９１ｂの室外側の端部上面及び端面は、断面形状「Ｌ」字型アングル材９３にて覆われ、「Ｌ」字型アングル材９３はねじ釘９６にて床材９１ｂに固定されている。なお、「Ｌ」字型アングル材９３の形状を明確なものとするために、図９（ｂ）の右下部の四辺形枠内に「Ｌ」字型アングル材９３の断面形状を示す。「Ｌ」字型アングル材９３の室外側端部と下枠９２の上面室内側端部とを拡大して示すのが図９（ｂ）左上部に円形に囲まれて参照符号Ｂで表されている図である。「Ｌ」字型アングル材９３の上面は下枠９２の上面より僅かに高くなるように設定されており、この段差を埋めるようにコーキング剤等によるシーリング９４ｂが施されている。
【０００５】
一方、図９（ａ）は、床材９１ａの厚さが下枠９２の高さより小さい場合を示している。この場合「Ｌ」字型アングル材９３の下面にスペーサ９５を入れ込んで下枠９２との高さの違いを調整している。また図９（ｃ）は、床材９１ｃの厚さが下枠９２の高さより大きい場合を示している。この場合「Ｌ」字型アングル材９３の上面は、下枠９２の上面より高くなるので、生じた段差の部分にコーキング剤等によるシーリング９４ｃが施されている。
【０００６】
【発明が解決しようとする課題】
しかし、上記の「Ｌ」字型アングル材９３と下枠９２との上面の間を、コーキング剤等を用いてシーリングの施工をするのに、手間がかかるという問題があった。
【０００７】
そこで、本発明は、シーリングする必要がない、異なる厚さの床材に同一サッシ下枠を兼用する方法、及び開口部装置を提供することを課題とする。
【０００８】
【課題を解決するための手段】
以下、本発明について説明する。なお、本発明の理解を容易にするために添付図面の参照符号を括弧書きにて付記するが、それにより本発明が図示の形態に限定されるものではない。
【０００９】
請求項１の発明は、異なる厚さの床材（４９、６９、７９ａ、７９ｂ）に同一サッシ下枠（２ｂ）を兼用する方法であって、下枠の室内寄り上面に嵌合溝（２５０）を設けるとともに、予め、下面の一端部側に嵌合溝に嵌入する嵌入部（４２）を備えるとともに上面側が少なくとも嵌合溝と床材の室外側端部上面を覆うことのできる平面を有する平面部材（４０）と、平面部と垂下部とを備えて、床材室外側端部上面及び室外側端面を覆うアングル材（６０）と、嵌合溝を覆うように嵌合溝に嵌合される溝蓋（６５）とを備え、
（１）床材上面と下枠上面との高さが同一の時は、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆い、
（２）床材上面の高さが下枠上面より高い場合には、床材の室外側端部にアングル材を取り付けるとともに、下枠の嵌合溝には溝蓋を嵌合させる、ことを特徴とする、異なる厚さの床材に同一サッシ下枠を兼用する方法を提供して前記課題を解決する。
【００１０】
請求項１の発明によれば、床材上面と下枠上面との高さが同一の時は、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆うので、平面部材が従来の断面「Ｌ」字状のアングル材と、シーリングの果たしていた機能を兼ね備えている。したがって、部品数、工数の削減ができ、材料及び人件費にかかるコストを削減することが容易となる。また、床材上面の高さが下枠上面より高い場合には、床材の室外側端部にアングル材を取り付けるとともに、下枠の嵌合溝には溝蓋を嵌合させることにより、上面の高さが下枠上面の高さより高い各種厚さの床材に、同一の下枠を兼用することが可能となる。
【００１１】
請求項２の発明は、異なる厚さの床材（４９、５９、６９、７９ａ、７９ｂ）に同一サッシ下枠（２ｂ）を兼用する方法であって、下枠の室内寄り上面に嵌合溝（２５０）を設けるとともに、予め、下面の一端部側に嵌合溝に嵌入する嵌入部（４２）を備えるとともに上面側が少なくとも嵌合溝と床材の室外側端部上面を覆うことのできる平面を有する平面部材（４０）と、平面部材と床材上面との間に挿入されるスペーサ（５０）と、平面部と垂下部とを備えて、床材室外側端部上面及び室外側端面を覆うアングル材（６０）と、嵌合溝を覆うように嵌合溝に嵌合される溝蓋（６５）とを備え、
（１）床材上面と下枠上面との高さが同一の時は、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆い、
（２）床材上面の高さが下枠上面の高さより低い場合には、平面部材と床材上面との間にスペーサを挿入して、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆い、
（３）床材上面の高さが下枠上面より高い場合には、床材の室外側端部にアングル材を取り付けるとともに、下枠の嵌合溝には溝蓋を嵌合させる
ことを特徴とする、異なる厚さの床材に同一サッシ下枠を兼用する方法により前記課題を解決する。
【００１２】
請求項２に記載の発明によれば、床材上面と下枠上面との高さが同一の時は、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆うので、平面部材が従来の断面「Ｌ」字状のアングル材と、シーリングの果たしていた機能を兼ね備えている。したがって、部品数、工数の削減ができ、材料及び人件費にかかるコストを削減することが容易となる。また、床材上面の高さが下枠上面の高さより低い場合には、平面部材と床材上面との間にスペーサを挿入して、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆う。すなわち床材上面の高さより下枠上面の高さが高い場合、平面部材をそのまま使用すると、下枠部と床材部との間に段差があるので、下枠部の平面部材下面側に隙間が生じてしまう。この隙間にスペーサを挿入するので、段差が解消して、床材上面と下枠上面との高さが同一の場合と同様に、平面部材が、従来の断面「Ｌ」字状のアングル材と、シーリングの果たしていた機能を兼ね備えることができる。したがって、部品数、工数の削減ができ、材料及び人件費にかかるコストを削減することが容易となる。また、床材上面の高さが下枠上面より高い場合には、床材の室外側端部にアングル材を取り付けるとともに、下枠の嵌合溝には溝蓋を嵌合させることにより、上面の高さが下枠上面の高さより高い各種厚さの床材に、同一の下枠を兼用することが可能となる。したがってこれらの構成により、床材上面の高さが下枠上面より高い場合でも、低い場合でも、また同一高さの場合でも一つの下枠を兼用することが可能となる。
【００１３】
請求項３の発明は、四辺の枠体（２ａ〜２ｄ）と、枠体内部に開閉可能に取り付けられた戸体（４）と、枠体の下枠（２ｂ）と室内床材（４９）との間隙を隠蔽するアタッチメントとを具備する開口部装置（１）であって、下枠の室内側上面に嵌合溝（２５０）を備え、アタッチメントは、下面の一端部側に嵌合溝に嵌入する嵌入部（４２）を備えるとともに、少なくとも嵌合溝の上方を覆い、及び床材の室外側端部上面に直接又は間接的に接触して該床材の上面端部を覆うことのできる平面を有する平面部材（４０）を具備し、平面部材を貫通して床材に達して平面部材と床材とを引き寄せて固定する固定部材（４３）を備え、下枠の嵌合溝に平面部材の下面側嵌入部が嵌入されるとともに、平面部材は嵌合溝の上方を覆い、及び床材の室外側端部上面に直接又は間接的に接触して配置されていることを特徴とする開口部装置により前記課題を解決する。

【００１５】

からなり、
（１）床材上面と下枠上面との高さが同一の時は、下枠の嵌合溝に（ａ）平面部材の下面側嵌入部が嵌入されるとともに、平面部材は嵌合溝と床材の室外側端部上面とを同時に覆うように配置され、

【００１８】
請求項５の発明によれば、床材上面と下枠上面との高さが同一の時は、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆うので、平面部材が従来の断面「Ｌ」字状のアングル材と、シーリングの果たしていた機能を兼ね備えている。したがって、部品数、工数の削減ができ、材料及び人件費にかかるコストを削減することが容易となる。また、床材上面の高さが下枠上面の高さより低い場合には、平面部材と床材上面との間にスペーサを挿入して、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆う。すなわち床材上面の高さより下枠上面高さが高い場合、平面部材をそのまま使用すると、下枠部と床材部との間に段差があるので、下枠部の平面部材下面側に隙間が生じてしまう。この隙間にスペーサを挿入するので、段差が解消して、床材上面と下枠上面との高さが同一の場合と同様に、平面部材が、従来の断面「Ｌ」字状のアングル材と、シーリングの果たしていた機能を兼ね備えることができる。したがって、部品数、工数の削減ができ、材料及び人件費にかかるコストを削減することが容易となる。また、床材上面の高さが下枠上面より高い場合には、床材の室外側端部にアングル材を取り付けるとともに、下枠の嵌合溝には溝蓋を嵌合させることにより、上面の高さが下枠上面の高さより高い各種厚さの床材に、同一の下枠を兼用することが可能となる。したがってこれらの構成により、床材上面の高さが下枠上面より高い場合でも、低い場合でも、また同一高さの場合でも一つの下枠を兼用することが可能となる開口部装置を提供することができる。
【００１９】
請求項６の発明は、請求項４または５に記載の開口部装置（１）において、アングル材（６０）のコーナー部には室外側に向けて水切り部（６３）が設けられていることを特徴とする。
【００２０】
請求項６の発明によれば、床材上面室外側端部に存在する結露水等は、アングル材の先端から溝蓋上面へと落下し、溝蓋上面から下枠室外側へと排出される。したがって床材側に水分が侵入してゆくことを抑制することが容易な開口部装置を提供することができる。
【００２１】
本発明のこのような作用及び利得は、次に説明する実施の形態から明らかにされる。
【００２２】
【発明の実施の形態】
以下本発明を図面に示す実施形態に基づき説明する。図１は、本発明の開口部装置を室内側視点より示す正面図である。図１において、開口部装置１はテラスドア等のドア装置で、開口部装置１は複層ガラスを備え、樹脂アルミ複合サッシドアとして構成されている。この開口部装置１は、建物の躯体の開口に取り付けられる枠体２と、この枠体２内に室外側に開閉可能に戸体４が取り付けられている。前記枠体２は、上枠２ａ、下枠２ｂおよび左右の縦枠２ｃ、２ｄにより四方枠状に形成されている。上枠２ａおよび左右の縦枠２ｃ、２ｄは、樹脂アルミ複合サッシからなり、略同一断面形状に形成されている。下枠２ｂは、押出し成型されたアルミニウムサッシにより形成されている。
【００２３】
戸体４は、上桟４ａと下桟４ｂと、左右の縦框４ｃ、４ｄからなる戸体枠にガラスパネル５がはめ込まれている。左縦框４ｃには蝶番３ａ、３ｂ、３ｃが取り付けられ、これを介して戸体４が枠体２の縦枠２ｃに回動可能に取り付けられている。右縦框４ｄの高さ方向略中央部にはドアノブ６が取り付けられている。使用者はドアノブ６に手を掛けてドアノブ６を垂直面内に回動させることにより、戸体４を蝶番３ａ、３ｂ、３ｃの軸芯の回りに回動させて室外側に開くことができる。
【００２４】
図２は、図１におけるII−II線に沿った垂直断面図である。図２の上端及び下端には上枠２ａと下枠２ｂとが表されている。上枠２ａは、室内側（図において右方向）に樹脂パネル２１を装着した上枠サッシ２２を備えている。上枠２２の室外側向き面の下端には上部戸当りパッキン２３が取り付けられている。下枠２ｂはアルミニウムサッシを主体に構成され、その室外側向きの面の上端には下部戸当りパッキン３０が取り付けられている。
【００２５】
上下の枠２ａ、２ｂの間には、戸体４が配置されている。戸体４は、上桟２ａと、下桟２ｂとを備えている。上桟２ａは、サッシ部２５と、サッシ部２５の室内側に装着された樹脂パネル２４とを備えている。同様に、下桟２ｂは、サッシ部２９と、サッシ部２９の室内側に装着された樹脂パネル２８とを備えている。上下のサッシ部２５及び２９の間にはグレージングチャネル２６、２７を介して、スペーサ３２、３３を狭持するように複層ガラス５ａ、５ｂが装着されている。
【００２６】
図３は、図１におけるIII−IIII線に沿った水平断面図である。図３に関する説明においては、図１〜図２において説明した部材と同一の部材は、それらと同一の参照符号を付して説明を省略する。
【００２７】
左縦枠２ｃには蝶番３ｂを介して戸体４が室外方向に開放化能に取り付けられている。左縦枠２ｃはアルミサッシ４１と、アルミサッシ４１に装着された樹脂パネル４２により構成されている。同様に右縦枠２ｄはアルミサッシ４３と、アルミサッシ４３に装着された樹脂パネル４４により構成されている。
【００２８】
戸体４の左縦框４ｃは、アルミサッシ４５と、アルミサッシ４５に装着された樹脂パネル４６により構成されている。同様に戸体４の右左縦框４ｄは、アルミサッシ４７と、アルミサッシ４７に装着された樹脂パネル４８により構成されている。左右の縦框４ｃ、４ｄの間にはグレージングチャネル４９、５０を介して、スペーサ５１、５２を狭持するように複層ガラスパネル５ａ、５ｂが配置されている。
【００２９】
以上に本発明にかかる開口部装置全体の構成概要を説明したが、本発明の特徴的な部分は、一定形状の下枠２ｂを異なる厚さの床材に兼用することにある。以下にこの特徴について、図４〜図７を参照しつつ説明する。
【００３０】
図４は、下枠の高さと床材の厚さとが一致している場合、図５は、下枠の高さが、床材上面より高い場合、図６は、下枠の高さが、床材上面より低い場合をそれぞれ表す図である。また、図７は、下枠高さと、床材上面との微調整を表す図である。これら各図においては、主に下枠２ｂと床材４９、５９、６９，７９とが表されている。
【００３１】
まず各図に共通する下枠２ｂについて図４を参照して説明する。下枠２ｂは、アルミニウム押出し材からなる第１部材１００と第２部材２００とが、断熱部材１５０を介して連結されている。第１部材１００、第２部材２００それぞれの下面は壁等に載置固定されている。第２部材２００の室内側上端には上向きに開口した溝部２５０が形成されている。また溝部２５０の室外側にはパッキン取り付け部２６０が形成されており、戸当りパッキン３０が取り付けられている。
【００３２】
図４は、上記したとおり下枠２ｂの高さと床材４９の厚さとが一致している場合を表す図である。この場合には、下枠の溝部２５０及び床材４９の室外側端部上面を覆うことのできる平面部材４０を使用する。平面部材４０は、図４の右下部の囲み部内に示すように平面部４１と、平面部４１の室外寄り下面側に設けられた嵌入部４２とを備えている。嵌入部４２は、下枠２ｂ上面に開口された溝部２５０内に嵌入され、平面部４１が固定部材４３により床材４９に固定されることにより、平面部材４０は、床材４９と下枠２ｂとの隙間を隠すように、両者の上面を覆う位置に固定される。このような構成をとることにより、床材４９の木口を隠蔽し、床材４９と下枠２ｂとの隙間から雨水等の水分が侵入するのを防止することができる。
【００３３】
図５は、上記したとおり下枠２ｂの高さが、床材５９上面より高い場合を表す図である。この場合には、下枠２ｂの上面が床材５９上面より高い分段差が生じるので、平面部材４０と床材５９との間にスペーサ５０を差し入れて、高さの均衡を図っている。図５の右下囲み部には、平面部材４０とスペーサ５０の断面形状を示した。このような構成により、下枠２ｂの高さが、床材５９上面より高い場合であっても、平面部材４０は、床材５９と下枠２ｂとの隙間を隠すように、両者の上面を覆う位置に固定され、床材５９の木口を隠蔽し、床材５９と下枠２ｂとの隙間から雨水等の水分が侵入するのを防止することができる。
【００３４】
図６は、上記したとおり下枠２ｂの高さが、床材６９の上面より低い場合を表す図である。かかる場合、平面部と垂下部とを備えて床材６９の室外側端部上面及び室外側端面を覆うアングル材６０と、溝部２５０を覆うように溝部に嵌合される溝蓋６５とを別体にして、床材６９及び下枠２ｂに取り付ける。図６の右下部囲み部に、アングル材６０、及び溝蓋６５の断面形状を示す。
【００３５】
アングル材６０は、床材６９の室外側端部上面を覆う平面部６１と、床材６９の木口を覆う垂下部６２とにより形成されている。平面部６１の室外側先端には、庇状の水切り部６３が設けられている。溝蓋６５は、頭部６６と、頭部６６の下面側に設けられた嵌合部６７ａ、６７ｂとを備えている。嵌合部６７ａ、６７ｂには返しが設けられていて、溝蓋６５が溝部２５０に嵌入されると、溝部２５０に設けられている返しと係合して、溝蓋６５が溝部２５０から抜け落ちることが規制される。
【００３６】
かかる構成により、床材６９の厚さが大きくても、アングル材６０、及び溝蓋６５の２部材に分けることにより、下枠２ｂとの段差に対応することができる。また、アングル材６０により床材６９の木口を隠蔽して、床材６９上に降り注ぐ雨水をアングル材６０の室外側先端の水切り６３から、溝蓋６５の頭部６６、さらに戸当りパッキン３０の上面から室外へと排出することができる。
【００３７】
図７は、下枠高さと、床材上面との微調整の方法を表す図である。この微調整は図７（ｂ）に示す、溝蓋７０の頭部７１の構造を二重構造とすることにより達成される。すなわち頭部７１を上頭部７１ａと、下頭部７１ｂとの二重構造とし、必要に応じて上頭部７１ａは、下頭部７１ｂの上面から剥ぎ取ることができるようにしておく。溝部２５０への嵌入部７４ａ、及び７４ｂは、下頭部７１ｂ下面側に形成する。かかる構成をとることにより、図７（ａ）に示す状態から、溝蓋７０の上頭部７１ａを剥ぎ取ることにより、床材７９ａよりわずかに薄い床材７９ｂに対応することが可能となる（図７（ｃ）参照）。このような構成は、左右の縦枠２ｃ、２ｄとの関係で、溝蓋頭部の厚さを図７（ａ）のように所定量とる必要がある場合に特に意義あるものである。
【００３８】
以上、現時点において、もっとも、実践的であり、かつ、好ましいと思われる実施形態に関連して本発明を説明したが、本発明は、本願明細書中に開示された実施形態に限定されるものではなく、請求の範囲および明細書全体から読み取れる発明の要旨或いは思想に反しない範囲で適宜変更可能であり、そのような変更を伴う、異なる厚さの床材に同一サッシ下枠を兼用する方法、及び開口部装置もまた本発明の技術的範囲に包含されるものとして理解されなければならない。
【００３９】
【発明の効果】
以上に説明したように、請求項１の発明によれば、床材上面と下枠上面との高さが同一の時は、平面部材の下面側嵌入部を下枠の嵌合溝に嵌入して平面部材にて嵌合溝と床材の室外側端部上面とを同時に覆うので、平面部材が従来の断面「Ｌ」字状のアングル材と、シーリングの果たしていた機能を兼ね備えている。したがって、部品数、工数の削減ができ、材料及び人件費にかかるコストを削減することが容易となる。また、床材上面の高さが下枠上面より高い場合には、床材の室外側端部にアングル材を取り付けるとともに、下枠の嵌合溝には溝蓋を嵌合させることにより、高さが下枠の高さより高い各種厚さの床材に、同一の下枠を兼用することが可能となる。
【００４０】

BACKGROUND OF THE INVENTION
The present invention relates to an opening device suitably used for a veranda or a terrace, and a method of using the same sash lower frame for floor materials of different thicknesses in the opening device.
[0002]
[Prior art]
In an opening device capable of entering and exiting a veranda or a terrace from the indoor side, the thickness of the flooring varies depending on the construction method employed. For example, in the conventional construction method, the typical thickness of the flooring is 40 mm. On the other hand, the 2 × 4 (two-by-four) construction method, which has recently been built a lot, is 27 mm. The thickness of the sash lower frame is usually determined. On the other hand, rainwater or the like is likely to enter from the gap between the end of the flooring and the lower frame.
[0003]
For example, in the case of the conventional construction method shown in FIG. 8, the thickness of the floor material 81 is determined to be 40 mm. Therefore, the height of the lower frame 82 is adjusted to match the height of the outdoor side of the upper surface of the floor material 81 and the lower frame 82. A cover member 83 that covers the upper surface is disposed on the upper surface of the both and fixed by screw nails 84. In this way, rainwater or the like enters from the gap between the indoor side end of the floor material 81 and the indoor side end of the lower frame 82, and the floor material 81 (often made mainly of wood) is inside. Is prevented from deteriorating.
[0004]
Further, when the thickness of the floor material changes, a step is generated between the sash lower frame and the floor material when the shape of the sash lower frame is set to a certain height. Especially when the height of the flooring is higher than the lower frame, the floor of the flooring is exposed. Corresponding to floor materials of various thicknesses, a cross-section "L" shape is formed on the outdoor end face of the floor material in order to conceal the above-mentioned exposed wooden mouth and the gap between the wooden mouth and the lower frame that are inevitably generated in construction Angle material is used. When trying to use a lower frame of a certain height for floor materials having different thicknesses as described above, the height of the lower frame is usually the most frequently used floor material thickness, that is, 2 × 4 (two-by-four) described above. It is set according to the floor material thickness of 27 mm. FIG.9 (b) shows the case where the thickness of a flooring is 27 mm. The upper surface and the end surface of the outdoor portion of the floor material 91 b are covered with a cross-sectional shape “L” -shaped angle material 93, and the “L” -shaped angle material 93 is fixed to the floor material 91 b with screw nails 96. Yes. In order to clarify the shape of the “L” -shaped angle member 93, the cross-sectional shape of the “L” -shaped angle member 93 is shown in the quadrilateral frame in the lower right part of FIG. An enlarged view of the outdoor side end portion of the “L” -shaped angle member 93 and the upper side indoor side end portion of the lower frame 92 is indicated by reference numeral B surrounded by a circle in the upper left part of FIG. It is a figure. The upper surface of the “L” -shaped angle member 93 is set to be slightly higher than the upper surface of the lower frame 92, and a sealing 94 b with a caulking agent or the like is applied so as to fill this step.
[0005]
On the other hand, FIG. 9A shows a case where the thickness of the flooring 91 a is smaller than the height of the lower frame 92. In this case, a spacer 95 is inserted into the lower surface of the “L” -shaped angle member 93 to adjust the difference in height from the lower frame 92. FIG. 9C shows a case where the thickness of the flooring 91 c is larger than the height of the lower frame 92. In this case, since the upper surface of the “L” -shaped angle member 93 is higher than the upper surface of the lower frame 92, a sealing 94 c with a caulking agent or the like is applied to the stepped portion.
[0006]
[Problems to be solved by the invention]
However, there is a problem that it takes time to perform sealing between the upper surfaces of the “L” -shaped angle member 93 and the lower frame 92 using a caulking agent or the like.
[0007]
Then, this invention makes it a subject to provide the method of using the same sash lower frame for the floor material of different thickness which does not need sealing, and an opening part apparatus.
