Description

【０００１】
【発明の属する技術分野】
本発明は、窓枠に障子を室内側に傾倒自在に装着した内倒し窓に関する。
【０００２】
【従来の技術】
実公平１−１５８２４号公報に示す内倒し窓が提案されている。
この内倒し窓は、図１０に示すように窓枠の下枠１００が、障子取付壁１０１を有する形状で、障子の下框１０２が取付片１０３を有する形状で、この取付片１０３の凹部を障子取付壁１０１に室内外側方向に揺動自在に嵌め込むことで障子が窓枠に、室内側に傾倒自在に装着してある。
前述の内倒し窓においては障子を閉じ状態で窓枠と障子との間を次のようにして気密・水密している。
窓枠の上枠、下枠１００の立上り壁１０４、左右縦枠に気密材１０５を四周連続して取付け、障子の上框、左右縦框の外向片の室外側面と前記下框１０２の取付片１０３の室外側面１０３ａを気密材１０５に圧接して気密・水密する。
【０００３】
【発明が解決しようとする課題】
前述のように窓枠と障子との間を気密・水密しても、気密材取付け誤差などの施工誤差や障子の建付け調整不良又は、強い雨が降っている際に障子を開放したままの場合には、下枠１００の立上り壁１０４と障子取付壁１０１との間の凹部１０６に雨水が流れ込んで溜る。
この雨水が障子取付壁１０１を越えて室内側に流れ落ちるので、前述した従来の内倒し窓においては、下枠１００の障子取付壁１０１よりも室内寄りに凹溝１０７を形成し、前述のように障子取付壁１０１を越えた雨水を凹溝１０７で受け、その凹溝１０７内の雨水を室外側に排水するようにしている。
【０００４】
このために、下枠１００が、障子取付壁１０１の室内寄りに凹溝１０７を有する形状であるから、その下枠１００の見込み寸法が大きくなってしまう。
【０００５】
本発明は、前述の課題を解決するためになされたもので、その目的は、雨水が、下枠を越えて室内側に流れ落ちることがないと共に、下枠の見込み寸法を小さくできるようにした内倒し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】
第１の発明は、上横枠材と下横枠材と左右の縦枠材を方形状に連結した窓枠と、
上框と下框と左右の縦框を方形状に連結し、パネルを装着した障子を有し、
前記下横枠材の障子取付片と、下框の取付片を室内外側方向に揺動自在に連結することで障子を室内側に傾倒可能とし、
前記下横枠材の障子取付片よりも室外側に、窓枠と障子との間の気密・水密部から洩れた雨水が流れ込む凹部を有する内倒し窓であって、
前記下横枠材の長手方向端部寄りに、前記凹部を室外側に連通する排水用部材を取付け、
前記排水用部材は、下框の取付片の先端部が室内外側方向に揺動自在に嵌まり合うと共に、その取付片の室内側への傾倒を規制する傾倒規制部を備えていることを特徴とする内倒し窓である。
【０００９】
第２の発明は、第１の発明において排水用部材は取付本体部と、この取付本体部の長手方向一端寄りに設けた排水部を有し、
その排水部は取付本体部の裏面よりも突出し、
前記取付本体部の裏面における長手方向中間部に、障子取付片が嵌まり込む凹溝を有し、長手方向他端部には、取付片が嵌まり込む凹部を有し、その凹溝と凹部との境い目に段差部を有し、
前記障子取付片の長手方向端面よりも取付片の長手方向端面が面内方向内側に位置し、
前記取付本体部の裏面を下横枠材の室内側面に取付けることで、その下横枠材の長手方向端部寄りに形成した切欠部に排水部が挿入され、その排水部と下横枠材の凹部の底部が連続し、前記凹溝に障子取付片が嵌まり込み、前記排水用部材の凹部と下横枠材の室内側面との間に凹陥部を形成し、
前記取付片が凹陥部に室内側方向に回動自在に嵌まり合うことで前記傾倒規制部とし、その取付片の長手方向端面が段差部に当接することで障子を面内方向に位置決めする位置決め部とした内倒し窓である。
【００１０】
【作用】
第１の発明によれば、何らかの事由で窓枠と障子との間の気密・水密部から洩れた雨水は、下横枠材の凹部に流れ込み、排水用部材を通って室外側に排水される。
したがって、下横枠材の障子取付片よりも室内側に排水用の凹部を形成する必要がなく、その障子取付片が最も室内側部とすることができるから、下横枠材の見込み寸法を小さくできる。
また、排水用部材で障子が大きく室内側に傾倒して脱落することを防止できる。
【００１３】
【発明の実施の形態】
図１に示すように、サッシ枠１と、このサッシ枠１に引き違いに装着した内障子２、外障子３と、その内障子２に取付けた換気用小窓４で換気用小窓付き引き違いサッシを形成している。
しかして、内障子２、外障子３を閉じた状態で換気用小窓４を開放することで室内と室外が連通し、室内を換気することができる。
【００１４】
前記サッシ枠１は上枠１ａと下枠１ｂと左右の縦枠１ｃを方形状に連結してある。
前記内障子２は、上框２ａと下框２ｂと召合せ框２ｃと戸当り框２ｄを方形状に連結し、その召合せ框２ｃの下部寄りと戸当り框２ｄの下部寄りに亘って中帯２ｅを連結することで上部開口部５と下部開口部６を有する框組体７を有する。
前記框組体７の上部開口部５にガラス８が装着してある。前記框組体７の下部開口部６に換気用小窓４が取付けてある。この換気用小窓４は窓枠４ａに障子４ｂを室内側に傾倒自在に取付けて、内倒し窓としてある。
前記外障子３は、上框３ａと下框３ｂと召合せ框３ｃと戸当り框３ｄを方形状に連結した框組体７にガラス８を装着してある。
前記各ガラス８は複層ガラスである。
【００１５】
次に、前述の換気用小窓４とした内倒し窓について説明する。
前記窓枠４ａは図２と図３に示すように、上横枠材１０と下横枠材１１と左右の縦枠材１２を方形状に連結してある。
前記障子４ｂは上框１３と下框１４と左右の縦框１５を方形状に連結し、その内部にパネル、例えば複層ガラス１６が装着してある。
前記窓枠４ａの上横枠材１０、下横枠材１１、左右の縦枠材１２は、前記中帯２ｅ、下框２ｂ、召合せ框２ｃ、戸当り框２ｄに着脱自在に取付けてあると共に、各枠材の室内側部は各框の室内側部よりも室内側に突出し、各枠材の室外側部と各框の室外側部は略面一である。
【００１６】
前記下横枠材１１は図２に示すように、中空形状の本体２０と、この本体２０の室内側部、例えば室内側壁２０ａの上部に一体的に設けた面内方向内側に向う障子取付片２１と、本体２０の室内外側方向中間部、例えば面内方向内側の内側壁２０ｂの室内外側方向中間部に、一体的に設けた面内方向内側に向う中間内向片２２を備えている。前記障子取付片２１の先端部（上端部）は室内外側方向に向う断面略円孤形状である。
前記下框１４は面内方向外側に向う室内側の取付片２３を備えている。
【００１７】
この室内側の取付片２３の先端部（下端部）は室内外側方向に向う断面略円孤形状に凹み、取付用凹部２４を形成している。
前記障子取付片２１の先端部と前記室内側の取付片２３の取付用凹部２４を室内外側方向に揺動自在に嵌め合せて連結することで、下横枠材１１に下框１４が室内外側方向に揺動自在に連結され、障子４ｂが窓枠４ａに室内側に傾倒自在に装着してある。
【００１８】
前記上横枠材１０の室内寄り部と縦枠材１２の室内寄り部と前記下横枠材１１の中間内向片２２に気密材装着部、例えば凹条溝１０ａ，１２ａ，２２ａが室内外側方向略同一位置として形成してある。
前記各凹条溝１０ａ，１２ａ，２２ａに気密材２５が四周連続して室内側に向けて装着してある。
【００１９】
障子４ｂを閉じることで、上框１３の室内側外向片２６、縦框１２の室内側外向片２７の室外側面２６ａ，２７ａと、前記下框１４の室内側の取付片２３の室外側面２３ａが、前記気密材２５にそれぞれ圧接し、窓枠４ａと障子４ｂとの間を気密・水密する。
【００２０】
下框１４の室内側の取付片２３の室外側面２３ａと下横枠材１１に装着した気密材２５との圧接部、つまり気密・水密部は、下横枠材１１の障子取付片２１と取付用凹部２４の嵌め合せ部、つまり障子取付部よりも上方位置である。
この気密・水密部から何らかの原因で浸入した雨水は、下横枠材１１における障子取付片２１と中間内向片２２と本体２０の内側壁２０ｂとで形成された凹部２８に流れ落ちて溜る。
【００２１】
図４に示すように、下横枠材１１の長手方向両端部（縦枠材１２との連結コーナー部）に排水用部材３０がそれぞれ取付けてある。この排水用部材３０は、前記凹部２８に流れ落ちた雨水を室外側に排水する。
前記排水用部材３０は図５に示すように、取付本体部３１と排水部３２を備えている。
前記取付本体部３１は所定の幅（室内外側方向の寸法）と高さ（上下方向の寸法）と長さ（左右方向の寸法）を有するブロック形状で、その裏面３１ａにおける長手方向一端寄りに上向きコ字状片３３が一体的に設けてある。この上向きコ字状片３３は裏面３１ａよりも突出して取付本体部３１の裏面３１ａよりも突出した排水部３２を形成している。
前記取付本体部３１の長手方向中間部下方には、その裏面３１ａと表面３１ｂに貫通した取付用孔３４が形成してある。
前記取付本体部３１の裏面３１ａにおける長手方向中間部上方には裏面側に開口した略横向きコ字形状の凹溝３５が形成してある。この凹溝３５の下内面３５ａは前記上向きコ字状片３３の上面３３ａと略面一に連続している。
前記取付本体部３１の裏面３１ａにおける長手方向他端寄り上方には、裏面３１ａと上面３１ｃに開口した断面略円孤形状の凹部３６が形成してある。この凹部３６は取付本体部３１の長さ方向他端面３１ｄまで連続し、その下面３６ａは凹溝３５の下内面３５ａよりも下方位置で、凹部３６の縦内面３６ｂは凹溝３５の縦内面（底部）３５ｂよりも表面３１ｂ寄りで、凹溝３５と凹部３６との境い目に段差部３７を有する。この段差部３７は長さ方向他端面３１ｄに向いている。
【００２２】
前記上向きコ字状片３３の取付本体部３１の裏面３１ａからの突出寸法は、下横枠材１１の本体２０における室内側壁２０ａから中間内向片２２までの室内外側方向の寸法よりも若干長い。
この上向コ字状片３３の突出端部の上部は切欠きされ、その切欠部３３ｂと取付本体部３１の裏面３１ａとの間の寸法は前述の室内側方向の寸法と略等しい。
前記上向きコ字状片３３（排水部３２）の高さは、前記下横枠材１１の内側壁２０ｂと外側壁２０ｃとの間の寸法と略等しい。
前記凹溝３５は障子取付片２１の先端部が嵌まり合う形状、大きさである。
【００２３】
次に、前記排水用部材３０の取付けについて図６〜図８に基づいて説明する。
前記下横枠材１１の長手方向両端寄りの室内側部分に、前記排水部３２（上向きコ字状片３３）が挿入する排水部挿入部が形成してある。
例えば、図８に示すように、下横枠材１１の本体２０における室内側壁２０ａと、内側壁２０ｂの中間内向片２２よりも室内寄り部の長手方向両端寄りをそれぞれ切欠きし、その切欠部４０を排水部挿入部とする。障子取付片２１の長手方向両端部も切欠きされる。
この切欠部４０の長さ（面内方向の寸法）は前記上向きコ字状片３３の幅（面内方向の寸法）と同一で、高さ（上下方向の寸法）は前記上向きコ字状片３３（排水部３２）の高さと同一である。
【００２４】
前記縦枠材１２の板状本体１２ｂの内面１２ｃと前記切欠部４０とで図６に示すように排水部挿入空間Ｅを形成する。
つまり、縦枠材１２の板状本体１２ｂの内面１２ｃに設けられた内向片４１における下部寄りを下横枠材１１の上下寸法に合せて切断して除去し、縦枠材１２の内面１２ｃ下部寄りを凹凸のない平坦面とする。
下横枠材１１の長手方向の端面１１ａを縦枠材１２の内面１２ｃにおける平坦面に突き当て、縦枠材１２からビスを下横枠材１１のビスホールに螺合して縦枠材１１の下端部に下横枠材１１を突き当て連結する。
これによって、縦枠材１２の内面１２ｃと切欠部４０との間に排水部挿入空間部Ｅを形成する。
【００２５】
下框１４の室内側の取付片２３は下横枠材１１の障子取付片２１よりも短かく、その室内側の取付片２３の長手方向端面２３ｂは障子取付片２１の長手方向端面２１ａよりも面内方向内側寄りである。
つまり、縦框１５の内面の内向片の下部寄りを切断して平坦面とし、その平坦面に下框１４の長手方向端面を突き当てビスで連結しているので、図６に示すように室内側の取付片２３の長手方向端面２３ｂは障子取付片２１の長手方向端面２１ａよりも面内方向内側寄りとなる。
【００２６】
窓枠４ａに障子４ｂを装着した状態で、排水用部材３０の排水部３２を前述の排水部挿入空間Ｅに挿入し、取付本体部３１の裏面３１ａを下横枠材１１の本体２０の室内側壁２０ａ（下横枠材１１の室内側面）に当接する。
取付用孔３４からビス３８を、前述の室内側壁２０ａに螺合して排水用部材３０を取付ける。
【００２７】
前記排水用部材３０の上向きコ字状片３３の面内方向一側面３３ｃが縦枠材１２の内面１２ｃと対向すると共に、取付本体部３１の上向きコ字状片３３の面内方向一側面３３ｃよりも突出した部分３１ｅが縦枠材１２（板状本体１２ｂ）の室内側端面１２ｄに当接する。
排水部３２は下横枠材１１の本体２０の中空部２０ｄに突出すると共に、下横枠材１１の本体２０の内側壁２０ｂ（つまり、凹部２８の底部）と連続する。
このようであるから、前述の凹部２８内に流れ落ちた雨水は排水部３２に流れ込み、その排水部３２から中空部２０ｄ内に流れる。
前記中空部２０ｄ内に流れた雨水は、図２に示すように排水穴５０を通って下框２ｂ内に流れ落ち、その下框２ｂの排水穴５１から下枠１ｂに流れ、下枠１ｂに沿って室外側に排水される。
【００２８】
よって、下横枠材１１の障子取付片２１よりも室内寄りに排水用の凹部を形成することがなく、その障子取付片２１を最も室内側部とすることができるので、下横枠材１１の見込み寸法を小さくできる。
【００２９】
図９に示すように、排水用部材３０の凹溝３５内に障子取付片２１の上端部が嵌まり込む。
排水用部材３０の凹部３６と下横枠材１１の本体２０の室内側壁２０ａとの間に上向きの凹陥部５２が形成される。この凹陥部５２が後述するように障子４ｂの傾倒規制部となる。
この凹陥部５２内に下框１４の室内側の取付片２３の先端部が室内外側方向に揺動自在に嵌まり込み、障子４ｂの脱落を防止する。
前記室内側の取付片２３の長手方向端面２３ｂが段差部３７に当接し、障子４ｂが面内方向に位置決めされる。
【００３０】
つまり、図９に仮想線で示すように障子４ｂが室内側にある程度傾倒すると、室内側の取付片２３の一部分が凹部３６の上端部（取付本体部３１の上面３１ｃ）に当接して室内側への傾倒を阻止し、障子４ｂが室内側に大きく傾倒し、室内側の取付片２３の取付用凹部２４が障子取付片２１の上端部から外れることを防止するので、障子４ｂが窓枠４ａから脱落することがない。
【００３１】
また、下框１４の室内側の取付片２３の長手方向端面２３ｂが左右の排水用部材３０の段差部３７にそれぞれ当接し、下框１４が左右方向に位置決めされるので、障子４ｂが面内方向に位置決めされる。この段差部３７が位置決め部である。
【００３２】
以上の実施の形態では換気用小窓として説明したが、通常一般の内倒し窓でも良いことは勿論である。
【００３３】
【発明の効果】
請求項１に係る発明によれば、何らかの事由で窓枠と障子との間の気密・水密部から洩れた雨水は、下横枠材の凹部に流れ込み、排水用部材を通って室外側に排水される。
したがって、下横枠材の障子取付片よりも室内側に排水用の凹部を形成する必要がなく、その障子取付片が最も室内側部とすることができるから、下横枠材の見込み寸法を小さくできる。
また、排水用部材で障子が大きく室内側に傾倒して脱落することを防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to an inward-facing window in which a shoji is attached to a window frame so as to be tiltable indoors.
[0002]
[Prior art]
An inward window shown in Japanese Utility Model Publication No. 1-15824 has been proposed.
As shown in FIG. 10, this inward-turning window has a shape in which the lower frame 100 of the window frame has a shoji mounting wall 101 and a lower arm of the shoji 102 has a mounting piece 103. The shoji is mounted on the window frame so as to be tiltable on the indoor side by being fitted to the shoji mounting wall 101 so as to be swingable in the direction of the outside of the room.
In the above-mentioned inward window, the shoji is closed and the space between the window frame and the shoji is airtight and watertight as follows.
An airtight material 105 is continuously attached to the upper frame of the window frame, the rising wall 104 of the lower frame 100, and the left and right vertical frames, and the outer side surface of the outer cover of the shoji and the left and right vertical frames and the mounting piece of the lower frame 102 The outdoor side surface 103a of 103 is pressed against the airtight material 105 to be airtight and watertight.
[0003]
[Problems to be solved by the invention]
As mentioned above, even if the window frame and the shoji are airtight and watertight, the shoji will remain open when installation errors such as airtight material installation errors, poor installation adjustment of the shoji, or heavy raining. In this case, rainwater flows into the recess 106 between the rising wall 104 of the lower frame 100 and the shoji mounting wall 101 and accumulates.
Since this rainwater flows down indoors beyond the shoji mounting wall 101, the conventional inward window described above forms a groove 107 closer to the room than the shoji mounting wall 101 of the lower frame 100, as described above. Rainwater that passes over the shoji mounting wall 101 is received by the concave groove 107, and the rainwater in the concave groove 107 is drained to the outdoor side.
[0004]
For this reason, since the lower frame 100 has a shape having the concave groove 107 closer to the interior of the shoji mounting wall 101, the expected size of the lower frame 100 is increased.
[0005]
The present invention has been made to solve the above-described problems, and has as its object to prevent rainwater from flowing down indoors beyond the lower frame and reducing the expected size of the lower frame. The purpose is to provide a fall window.
[0006]
[Means for Solving the Problems]
1st invention, the window frame which connected the upper horizontal frame material, the lower horizontal frame material, and the left and right vertical frame materials in the shape of a rectangle,
The upper and lower heels and the left and right vertical ridges are connected in a square shape and have a shoji with a panel.
The shoji can be tilted to the indoor side by connecting the shoji mounting piece of the lower horizontal frame material and the mounting piece of the lower heel so as to be swingable in the indoor outside direction,
An inward window having a recess into which rainwater leaked from an airtight / watertight portion between the window frame and the shoji flows outside the shoji mounting piece of the lower horizontal frame material,
A drainage member that communicates the concave portion with the outdoor side is attached near the longitudinal direction end of the lower horizontal frame member ,
The drainage member is provided with a tilt restricting portion for restricting the tilt of the mounting piece toward the indoor side while the tip end portion of the lower hook mounting piece fits in a swingable manner in the indoor outside direction. It is an inversion window.
[0009]
According to a second aspect of the present invention, in the first aspect, the drainage member has an attachment main body portion and a drainage portion provided near one end in the longitudinal direction of the attachment main body portion,
The drainage part protrudes from the back of the mounting body part,
There is a concave groove into which the shoji mounting piece fits in the middle portion in the longitudinal direction on the back surface of the mounting main body, and a concave portion into which the mounting piece fits into the other end in the longitudinal direction. Has a step at the boundary with
The longitudinal end surface of the mounting piece is located on the inner side in the in-plane direction than the longitudinal end surface of the shoji mounting piece,
By attaching the back surface of the mounting main body portion to the indoor side surface of the lower horizontal frame member, the drainage portion is inserted into the notch formed near the longitudinal end of the lower horizontal frame member, and the drainage portion and the lower horizontal frame member The bottom of the concave portion is continuous, a shoji mounting piece is fitted into the concave groove, and a concave portion is formed between the concave portion of the drainage member and the indoor side surface of the lower horizontal frame member,
Positioning for positioning the shoji in the in-plane direction when the mounting piece fits into the recessed portion so as to be pivotable in the indoor direction to form the tilt restricting portion, and the longitudinal end surface of the mounting piece abuts the stepped portion. It is an interior fall window.
[0010]
[Operation]
According to the first invention, rainwater leaking from the airtight / watertight portion between the window frame and the shoji for some reason flows into the recess of the lower horizontal frame member and is drained to the outdoor side through the drainage member. .
Therefore, it is not necessary to form a recessed portion for drainage on the indoor side of the shoji mounting piece of the lower horizontal frame material, and the shoji mounting piece can be the most indoor side portion. Can be small.
In addition, the drainage member can prevent the shoji from being greatly inclined to the indoor side and falling off.

Next, attachment of the drainage member 30 will be described with reference to FIGS.
A drainage portion insertion portion into which the drainage portion 32 (upward U-shaped piece 33) is inserted is formed in the indoor side portion of the lower horizontal frame member 11 near both longitudinal ends.
For example, as shown in FIG. 8, the interior side wall 20a of the main body 20 of the lower horizontal frame member 11 and the longitudinally opposite ends of the interior side portion of the inner side wall 20b are cut away from both ends in the longitudinal direction. 40 is a drainage part insertion part. Both ends in the longitudinal direction of the shoji mounting piece 21 are also cut out.
The length (dimension in the in-plane direction) of the notch 40 is the same as the width (dimension in the in-plane direction) of the upward U-shaped piece 33 and the height (vertical dimension) is the upward U-shaped piece. 33 (drainage part 32) is the same height.
[0024]
A drainage portion insertion space E is formed by the inner surface 12c of the plate-like main body 12b of the vertical frame member 12 and the cutout portion 40 as shown in FIG.
That is, the lower part of the inwardly facing piece 41 provided on the inner surface 12c of the plate-like main body 12b of the vertical frame member 12 is cut and removed according to the vertical dimension of the lower horizontal frame member 11, and the lower portion of the inner surface 12c of the vertical frame member 12 is removed. Make the side flat with no irregularities.
The end surface 11a in the longitudinal direction of the lower horizontal frame member 11 is abutted against the flat surface of the inner surface 12c of the vertical frame member 12, and screws from the vertical frame member 12 are screwed into the screw holes of the lower horizontal frame member 11 to The lower horizontal frame member 11 is abutted and connected to the lower end.
As a result, a drainage portion insertion space E is formed between the inner surface 12 c of the vertical frame member 12 and the notch 40.
[0025]
The indoor side mounting piece 23 of the lower rod 14 is shorter than the shoji mounting piece 21 of the lower horizontal frame member 11, and the longitudinal end surface 23 b of the indoor side mounting piece 23 is longer than the longitudinal end surface 21 a of the shoji mounting piece 21. Inward in the in-plane direction.
That is, the lower portion of the inner surface of the vertical rod 15 near the lower part of the inward piece is cut to be a flat surface, and the longitudinal end surface of the lower rod 14 is connected to the flat surface by the abutting screw. As shown in FIG. The longitudinal end surface 23 b of the inner attachment piece 23 is closer to the inner side in the in-plane direction than the longitudinal end surface 21 a of the shoji attachment piece 21.
[0026]
With the shoji 4b attached to the window frame 4a, the drainage portion 32 of the drainage member 30 is inserted into the drainage portion insertion space E described above, and the back surface 31a of the mounting main body portion 31 is placed in the interior of the main body 20 of the lower horizontal frame member 11. It contacts the side wall 20a (the indoor side surface of the lower horizontal frame member 11).
A screw 38 is screwed into the indoor side wall 20a from the mounting hole 34 to attach the drainage member 30.
[0027]
One side surface 33c in the in-plane direction of the upward U-shaped piece 33 of the drainage member 30 faces the inner surface 12c of the vertical frame member 12, and one side surface 33c in the in-plane direction of the upward U-shaped piece 33 of the mounting main body 31. The part 31e that protrudes further contacts the indoor side end face 12d of the vertical frame member 12 (plate-like main body 12b).
The drainage portion 32 protrudes into the hollow portion 20d of the main body 20 of the lower horizontal frame member 11 and continues to the inner wall 20b of the main body 20 of the lower horizontal frame member 11 (that is, the bottom portion of the recess 28).
Since it is like this, the rainwater which flowed down in the above-mentioned recessed part 28 flows into the drainage part 32, and flows into the hollow part 20d from the drainage part 32. FIG.
As shown in FIG. 2, the rainwater flowing into the hollow portion 20d flows down into the lower gutter 2b through the drainage hole 50, flows from the drainage hole 51 of the lower gutter 2b to the lower frame 1b, and follows the lower frame 1b. Drained to the outside.
[0028]
Therefore, since the concave part for drainage is not formed nearer the room than the shoji attaching piece 21 of the lower horizontal frame member 11 and the shoji attaching piece 21 can be the most indoor side portion, the lower horizontal frame member 11 The expected size of can be reduced.
[0029]
As shown in FIG. 9, the upper end portion of the shoji attachment piece 21 is fitted into the concave groove 35 of the drainage member 30.
An upward recessed portion 52 is formed between the recessed portion 36 of the drainage member 30 and the indoor side wall 20a of the main body 20 of the lower horizontal frame member 11. As will be described later, the recessed portion 52 serves as a tilt restricting portion for the shoji 4b.

[0030]
That is, as shown in phantom lines in FIG. 9, when the shoji 4 b is tilted to the indoor side to some extent, a part of the indoor mounting piece 23 comes into contact with the upper end of the recess 36 (the upper surface 31 c of the mounting main body 31). The shoji 4b is largely tilted to the indoor side, and the mounting recess 24 of the mounting piece 23 on the indoor side is prevented from being detached from the upper end of the shoji mounting piece 21, so that the shoji 4b can be removed from the window frame 4a. Will not fall off.
[0031]
Further, the longitudinal end surface 23b of the mounting piece 23 on the indoor side of the lower rod 14 abuts on the stepped portions 37 of the left and right drainage members 30, respectively, and the lower rod 14 is positioned in the left-right direction. Positioned in the direction. The step portion 37 is a positioning portion.
[0032]
In the above embodiment, although it demonstrated as a small window for ventilation, it is needless to say that a general inversion window may be used normally.
[0033]
