As described above, in the present embodiment, the lower surface of the lower stile is brought into contact with the airtight material arranged on the upper surface of the lower frame by raising and lowering the shoji to the lower frame having a substantially flat upper surface, whereby the first airtightness is achieved. The line is formed, and the drainage such as rainwater generated on the outdoor side of the first airtight line is drained through the first drainage path formed in the outdoor region of the first airtight line.
Further, the drainage generated on the indoor side of the first airtight line is drained through the second drainage route completely independent of the first drainage route from the indoor side region to the outdoor side region of the airtight line. There is.
A drainage hole leading to the first drainage path formed in the outdoor region is formed on the upper surface of the lower frame in a wide range along the longitudinal direction.
Therefore, drainage such as rainwater in the outdoor region of the airtight line can be quickly drained without staying near the contact surface between the lower stile and the airtight material before reaching the airtight line, and invasion into the room can be prevented. In addition, rainwater on the outdoor side of the fitting does not affect the drainage route on the indoor side, the load on the second drainage route can be suppressed, and an efficient drainage structure can be realized.

また、障子と下枠との第1の気密ラインの室内側に、下框の垂下片221cが挿入可能な排水孔を下枠上面に形成するとともに、排水孔の側面には、室内樹脂カバーに取り付けられためくれ上がることがない半円ホロー形状の軟質の気密材が配置されて垂下片221cの側面に当接させて第2の気密ラインを形成しているので、第1の気密ラインを超えて進入した雨水等を垂下片221cによって室内側溝に導くことができるとともに、それ以上室内側に侵入することを防ぐことができる。 Further, on the indoor side of the first airtight line between the shoji and the lower frame, a drain hole into which the hanging piece 221c of the lower stile can be inserted is formed on the upper surface of the lower frame, and the side surface of the drain hole is covered with an indoor resin cover. A semi-circular hollow-shaped soft airtight material that is attached and does not fold up is arranged and abuts on the side surface of the hanging piece 221c to form a second airtight line, so that it exceeds the first airtight line. The rainwater or the like that has entered the room can be guided to the indoor gutter by the hanging piece 221c, and can be prevented from further entering the room.

さらに、第1の気密ラインを形成する下框の下面と気密材の当接方向を上下方向とし、第2の気密ラインを形成する垂下片221cと第2止水材との当接方向を見込み方向とすることで、上下方向と内外方向の異なる二方向の当接による二つの気密ラインを形成しているので、障子の下框が上下内外のいずれか一方にずれる誤差が発生したとしても、必ずいずれかの気密ラインを維持することができ、多少の誤差が発生した場合でも、所定の止水性能を維持することができる。 Further, the contact direction between the lower surface of the lower stile forming the first airtight line and the airtight material is set in the vertical direction, and the contact direction between the hanging piece 221c forming the second airtight line and the second water blocking material is expected. By setting the direction, two airtight lines are formed by contact in two directions, which are different in the vertical direction and the inner and outer directions, so even if an error occurs in which the lower stile of the obstacle shifts to either the upper, lower, inner or outer direction. Any of the airtight lines can be maintained without fail, and even if some error occurs, the predetermined water stopping performance can be maintained.

さらに、障子と下枠との気密ラインの室内側に配置した室内樹脂カバーの上面に浅溝部を形成しているので、垂下片221cを越えて乗り上げてきた雨水を浅溝部で受け止めるとともに、浅溝部の底面に穿設した排水孔から、下枠内部の室内排水領域に落下させ、そして、排水孔から室内流入領域に流下してきた水と合流させて、逆止弁を経由して屋外に排出させることができ、雨水の室内への侵入をより確実に防止することができる。 Furthermore, since a shallow groove is formed on the upper surface of the indoor resin cover arranged on the indoor side of the airtight line between the shoji and the lower frame, the shallow groove catches the rainwater that has run over the hanging piece 221c and also the shallow groove. It is dropped from the drainage hole drilled in the bottom of the frame into the indoor drainage area inside the lower frame, and then merged with the water flowing down from the drainage hole into the indoor inflow area and discharged to the outside via the check valve. It is possible to prevent rainwater from entering the room more reliably.

また、第1の排水経路及び第2の排水経路を構成する室内排水溝及び室外排水溝を、取り外し可能である室外側カバー部材や室内側カバー部材により覆って形成しているので、下枠上面を略フラットにすることができるとともに、異物が進入しやすい室内外排水溝内を容易に開放でき、清掃性を向上できる。 Further, since the indoor drainage groove and the outdoor drainage groove constituting the first drainage path and the second drainage path are covered with removable outdoor cover members and indoor side cover members, the upper surface of the lower frame is formed. Can be made substantially flat, and the inside of the indoor / outdoor drainage ditch where foreign matter can easily enter can be easily opened, and the cleanability can be improved.

さらに、下枠の室外側にテーブルなどのカウンタを固定することができ、かつ、下枠に固定したカウンタは、面一に形成した下枠上面と略面一に取付けているので、下枠上面を、室内側からカウンタの室外側端に至るまで面一に形成することができ、使い勝手にすぐれた開口部を形成することができる。
また、カウンタを固定するための固定部は、室外カバー部材の室外端部によって覆われているので、部品点数を増やすことなく、カウンタの取付如何にかかわらずカウンタの固定部を隠すことができ、腐食を防ぐと共に意匠性を向上させることができる。
Further, a counter such as a table can be fixed to the outdoor side of the lower frame, and the counter fixed to the lower frame is attached substantially flush with the upper surface of the lower frame formed flush with each other. Can be formed flush with each other from the indoor side to the outdoor end of the counter, and an opening having excellent usability can be formed.
Further, since the fixing portion for fixing the counter is covered by the outdoor end portion of the outdoor cover member, the fixed portion of the counter can be hidden regardless of the mounting of the counter without increasing the number of parts. It is possible to prevent corrosion and improve the design.

なお、第1排水経路及び第2排水経路の各排水孔を設ける位置は何ら限定されるものではないが、下枠の長手方向で異なる位置に、室外流入領域の排出孔と、室内流入領域の逆止弁を備えた排出孔を配置することで、室外流入領域の排水が下枠の長手方向に飛散したとしても、より確実に逆止弁の開閉動作に不具合を起こすことを抑制でき、高い排水性能を維持できて好ましい。
なお、本実施形態においては、サッシとして上げ下げ窓を用いて説明したが、本発明が採用されるサッシは、上げ下げ窓に限定されるものではなく、また、枠体と障子との気密ラインの構成等についても、何ら限定されるものではない。
The positions where the drain holes of the first drainage path and the second drainage path are provided are not limited at all, but the drain holes of the outdoor inflow region and the indoor inflow region are located at different positions in the longitudinal direction of the lower frame. By arranging the discharge hole provided with the check valve, even if the drainage in the outdoor inflow area is scattered in the longitudinal direction of the lower frame, it is possible to more reliably suppress the malfunction of the check valve opening / closing operation, which is high. It is preferable because the drainage performance can be maintained.
In the present embodiment, the sash window is used as the sash window, but the sash used in the present invention is not limited to the sash window, and the structure of the airtight line between the frame and the shoji screen. Etc. are not limited in any way.
