Description

本発明は、サッシ枠に障子を開閉自在に装着したサッシ、詳しくはサッシ枠と障子との間の水密部から浸入した雨水等を室外側に排水する構造に関する。 The present invention relates to a sash in which a shoji is attached to a sash frame so as to be freely opened and closed, and more particularly, to a structure for draining rainwater or the like that has entered from a watertight portion between the sash frame and the shoji to the outdoor side.

サッシ枠に障子を開閉自在に装着したサッシにおいては、そのサッシ枠と障子との間を水密材によって水密して障子よりも室内側に雨水等が浸入しないようにしている。
しかしながら、強風雨時には、水密部を通って雨水等が障子よりも室内側に浸入することがある。
この室内側に浸入した雨水等は下枠上面に溜り、その水位が下枠室内側部よりも高くなると室内側に流れるので、その雨水等を室外側に排水するようにしたサッシが特許文献１に開示されている。
このサッシは、下枠の上面における障子よりも室内側に溜った雨水等を集水口で下枠の中空部に導入し、その中空部を通して排水口から室外側に排水するようにし、前記中空部を空気抜き孔でサッシにおける障子よりも室内側の空間に連通して強風雨時に中空部の気圧が高まっても、その気圧を直ちに前述の室内側の空間に逃すことで、集水口からの吹き出しがないようにし、前述の下枠の上面に溜った雨水等が室内側にしぶきにくくしている。 In a sash having a sash frame that can be opened and closed, the sash frame and the sash are watertight with a watertight material so that rainwater or the like does not enter the interior of the sash frame.
However, during strong winds and rain, rainwater and the like may enter the indoor side of the shoji through the watertight part.
The rainwater or the like that has entered the indoor side accumulates on the upper surface of the lower frame, and flows to the indoor side when the water level becomes higher than the lower frame indoor side, so a sash that drains the rainwater or the like to the outdoor side is disclosed in Patent Document 1. Is disclosed.
The sash is configured to introduce rainwater or the like accumulated on the indoor side of the shoji on the upper surface of the lower frame into the hollow portion of the lower frame at the water collection port, and drain the water from the drain port to the outdoor side through the hollow portion. Even if the air pressure in the hollow part increases through the air vent hole to the indoor space rather than the shoji screen in the sash and the air pressure in the hollow part increases during heavy winds and rains, The rainwater etc. collected on the upper surface of the lower frame is not easily splashed indoors.

特開２０００−１７９６５号公報JP 2000-17965 A

前述の従来のサッシは、下枠に集水口、排水口を加工すると共に、この集水口とは別に空気抜き孔を加工するので、排水のための加工個所が多く、その加工作業が面倒で、時間がかかるから、製作コストが高いサッシである。 The conventional sash mentioned above has a water collecting port and a drain port in the lower frame, and an air vent hole is processed separately from this water collecting port, so there are many processing points for drainage, and the processing work is troublesome and time consuming. Therefore, it is a sash with high production cost.

本発明の目的は、下枠の上面における障子よりも室内側に浸入した雨水等を室外側に排水でき、その雨水等が強風雨時に室内側にしぶきにくく、しかも排水のための加工個所が少なく製作コストが安いサッシを提供することである。 The object of the present invention is to allow rainwater, which has entered the indoor side of the upper frame of the lower frame, to be drained to the outside of the room. It is to provide a sash with a low production cost.

本発明は、上枠と下枠と左右の縦枠を備えたサッシ枠に障子を開閉自在に装着したサッシにおいて、
前記縦枠は、中空部を有すると共に、その中空部をサッシにおける障子よりも室内側空間に開口する排水用開口部が形成され、
この排水用開口部の下部は、前記下枠の上面における障子よりも室内側部分の雨水溜め部と連続し、かつその上部は前記雨水溜め部に溜った雨水等の最高水位よりも上方に位置し、
前記下枠の上面における前記雨水溜め部に、カバー体を、前記縦枠の内面に接して前記排水用開口部を覆うように設け、
このカバー体の上面板における前記縦枠の内面に接する端面を切欠き、この切欠部と前記縦枠の内面によって、前記排水用開口部の上部を室内側空間に連通する空気抜き孔部を形成し、
前記下枠は中空部を有し、その下枠の中空部は前記縦枠の中空部に連通し、この下枠の中空部を排水孔で室外側に開口したことを特徴とするサッシである。 The present invention is a sash in which a shoji is detachably mounted on a sash frame having an upper frame, a lower frame, and left and right vertical frames,
The vertical frame, which has a hollow portion, discharge apertures which open to the indoor side space than Shoji the hollow portion of the sash is formed,
The lower part of the drainage opening is continuous with the rainwater reservoir on the indoor side of the shoji on the upper surface of the lower frame, and the upper part is located above the highest water level of rainwater etc. collected in the rainwater reservoir. And
A cover body is provided in the rainwater reservoir on the upper surface of the lower frame so as to cover the drainage opening in contact with the inner surface of the vertical frame,
An end surface of the upper surface plate of the cover body that is in contact with the inner surface of the vertical frame is cut out, and an air vent hole portion that connects the upper portion of the drainage opening to the indoor space is formed by the cutout portion and the inner surface of the vertical frame. ,
The lower frame has a hollow portion, the hollow portion of the lower frame communicates with the hollow portion of the vertical frame, and the hollow portion of the lower frame is opened to the outdoor side by a drainage hole. .

請求項１に係る発明によれば、強風雨時に下枠の上面における障子よりも室内側に浸入した雨水等は、排水用開口部の下部から縦枠の中空部を通って室外側に排水される。
また、排水用開口部がカバー体で見えないから見栄えが良い。
また、強風雨時に縦枠の中空部の気圧が高くなった場合には、その気圧が排水用開口部の上部から空気抜き孔部を通って、直ちにサッシにおける障子よりも室内側空間に逃げるので、前述の障子よりも室内側に浸入し雨水溜め部に溜った雨水等が室内側にしぶきにくい。
しかも、前記空気抜き孔部は、カバー体の上面板の端面に形成した切欠部と縦枠の内面とで形成され、前述の気圧は縦枠の内面に沿って室内側空間に逃げるので、雨水溜め部に溜まった雨水等が室内にしぶくことがより一層低減する。
また、浸入した雨水等を排水する排水用開口部を利用して縦枠の中空部の気圧を室内側空間に逃がすので、排水のための加工個所が少なく、加工作業が簡単で、短時間に加工できるから、製作コストの安いサッシである。
また、下枠は中空部を有し、その下枠の中空部が縦枠の中空部に連通し、この下枠の中空部を排水孔で室外側に開口しているので、排水孔の数や大きさで、その面積を調整することによって、中空部内の圧力を外気よりも低くして、その中空部内の圧力と室内側空間の圧力の圧力差を小さくすることができるから、下枠の雨水溜め部に溜まった雨水等を中空部を通して室外側にスムーズに排水できる。 According to the first aspect of the present invention, rainwater or the like that has entered the indoor side of the shoji on the upper surface of the lower frame during heavy winds is drained from the lower part of the drainage opening to the outdoor side through the hollow part of the vertical frame. The
Moreover, since the opening part for drainage cannot be seen with a cover body, it looks good.
In addition, when the atmospheric pressure of the hollow portion of the vertical frame becomes high during heavy rain, the atmospheric pressure immediately escapes from the upper part of the drainage opening through the air vent hole to the indoor space rather than the shoji in the sash. Rainwater or the like that enters the indoor side and collects in the rainwater reservoir is less likely to splash into the indoor side than the aforementioned shoji screen .
In addition, the air vent hole is formed by a notch formed on the end face of the top plate of the cover body and the inner surface of the vertical frame, and the atmospheric pressure escapes to the indoor space along the inner surface of the vertical frame. It is further reduced that rainwater or the like accumulated in the room splashes into the room.
In addition, since the atmospheric pressure in the hollow part of the vertical frame is released to the indoor space using the drainage opening that drains rainwater that has entered, the number of processing points for drainage is small, the processing work is simple, and in a short time Because it can be processed, it is a low-cost sash.
Further, the lower frame has a hollow portion, the hollow portion of the lower frame communicates with the hollow portion of the vertical frame, and the hollow portion of the lower frame is opened to the outdoor side by a drainage hole. By adjusting the area with the size of the lower part, the pressure in the hollow part can be made lower than the outside air, and the pressure difference between the pressure in the hollow part and the pressure in the indoor space can be reduced. Rainwater or the like collected in the rainwater reservoir can be smoothly drained to the outside through the hollow portion.

図１と図２に示すように、サッシを構成するサッシ枠１は上枠２と下枠３と左右の縦枠４を方形枠組みしてある。
前記サッシ枠１内に障子５が開閉自在に装着してある。
この障子５とサッシ枠１との間が水密材で水密され、障子５よりも室内側に室外側から雨水等が浸入しないようにしてある。
このようにしても、強風雨時に前述の水密部を通って雨水等が障子５よりも室内側に浸入することがあり、その室内側に浸入した雨水等は下枠３の上面３ａにおける障子５よりも室内側部分に溜る。 As shown in FIGS. 1 and 2, the sash frame 1 constituting the sash has an upper frame 2, a lower frame 3, and left and right vertical frames 4 that are rectangularly framed.
A shoji 5 is mounted in the sash frame 1 so as to be freely opened and closed.
The space between the shoji 5 and the sash frame 1 is water-tight with a water-tight material so that rainwater or the like does not enter the indoor side of the shoji 5 from the outdoor side.
Even in this case, rainwater or the like may enter the indoor side of the shoji 5 through the above-mentioned watertight portion during strong wind and rain, and the rainwater or the like that has entered the indoor side may be the shoji 5 on the upper surface 3a of the lower frame 3. It collects in the indoor side part.

この実施の形態では、内障子５ａと外障子５ｂを備えた引き違いサッシとしてある。そして、内障子５ａ、外障子５ｂを構成する上框６と上枠２、下框７と下枠３、戸当り框８と縦枠４の間がそれぞれ気密材９で水密され、図示しない召合せ框相互が召合せ気密材で水密されて、前記内障子５ａ、外障子５ｂよりも室内側に雨水等が浸入しないようにしてある。
このようにしても、強風雨時に水密部を通して内・外障子５ａ，５ｂよりも室内側に雨水等が浸入することがあり、その雨水等は下枠３の上面３ａにおける外障子５ｂと対向した部分に溜る。
なお、サッシは引き違いサッシに限ることはなく、片引きサッシ、三枚建てサッシ、外開きサッシ、内開きサッシ、すべり出しサッシ等でも良いことは勿論である。 In this embodiment, the sliding sash is provided with an inner impediment 5a and an outer imperial 5b. Then, an upper seal 6 and an upper frame 2, a lower fence 7 and a lower frame 3, and a door-to-door fence 8 and a vertical frame 4, which constitute the inner and outer children 5 a and 5 b, are watertight with an airtight material 9. The mating tubs are watertight with a summing airtight material so that rainwater or the like does not enter the indoor side more than the inner shoji 5a and outer shoji 5b.
Even in this case, rainwater or the like may enter the indoor side of the inner / outer shoji 5a and 5b through the watertight part during strong wind and rain, and the rainwater or the like faces the outer shoji 5b on the upper surface 3a of the lower frame 3. Accumulate in the part.
Of course, the sash is not limited to a sliding sash, and may of course be a one-way sash, a three-story sash, an outer opening sash, an inner opening sash, a sliding sash, or the like.

前記縦枠４は中空部４ａを有している。この中空部４ａは排水用開口部１０で前記サッシにおける障子５よりも室内側空間Ａに開口している。
この排水用開口部１０は図３と図４に示すように、前記下枠３の上面３ａにおける浸入した雨水等が溜る雨水溜め部１１と室内外側方向に同一である。
そして、排水用開口部１０の下開口縁１０ａは前記雨水溜め部１１における下枠３の上面３ａと同一、又は高く、かつその雨水溜め部１１に溜った雨水等の最大水位Ｈよりも低い位置で、この排水用開口部１０の下部が雨水溜め部１１と連続し、その雨水溜め部１１に溜った雨水等を縦枠４の中空部４ａに排水する雨水排水部である。前記最大水位Ｈは図３に示すように下枠３の室内側立上り部３ｂの高さで決定される。つまり、雨水溜め部１１に溜った雨水は室内側立上り部３ｂを越えて室内側に流入するので、その水位は室内側立上り部３ｂ以上にはならない。
前記排水用開口部１０の上開口縁１０ｂは最大水位Ｈよりも高い位置で、その排水用開口部１０の上部が、縦枠４の中空部４ａ内の気圧（空気圧）を前述の室内側空間Ａに逃がす空気抜き部である。
前記縦枠４の中空部４ａは室外側に開口連通している。 The vertical frame 4 has a hollow portion 4a. This hollow portion 4a is an opening 10 for drainage, and opens to the indoor space A rather than the shoji 5 in the sash.
As shown in FIGS. 3 and 4, the drain opening 10 is the same as the rain water reservoir 11 in which rainwater or the like that has entered in the upper surface 3 a of the lower frame 3 accumulates in the indoor exterior direction.
The lower opening edge 10a of the drainage opening 10 is the same as or higher than the upper surface 3a of the lower frame 3 in the rainwater reservoir 11 and is lower than the maximum water level H of rainwater or the like accumulated in the rainwater reservoir 11. The lower part of the drainage opening 10 is continuous with the rainwater reservoir 11, and is a rainwater drainage that drains rainwater and the like accumulated in the rainwater reservoir 11 into the hollow portion 4 a of the vertical frame 4. The maximum water level H is determined by the height of the indoor rising portion 3b of the lower frame 3 as shown in FIG. That is, the rainwater collected in the rainwater reservoir 11 flows into the indoor side beyond the indoor rising part 3b, so that the water level does not exceed the indoor rising part 3b.
The upper opening edge 10b of the drainage opening 10 is at a position higher than the maximum water level H, and the upper part of the drainage opening 10 changes the air pressure (air pressure) in the hollow part 4a of the vertical frame 4 to the above-described indoor space. It is an air vent part which escapes to A.
The hollow portion 4a of the vertical frame 4 is in open communication with the outdoor side.

このようであるから、強風雨時に障子５の室内側に浸入した雨水等は下枠３の上面３ａにおける雨水溜め部１１に溜る。
この雨水溜め部１１に溜った雨水等は排水用開口部１０の下部から縦枠４の中空部４ａに流出し、その中空部４ａから室外側に排水される。
また、強風雨時に中空部４ａの気圧が高まっても、その気圧を直ちに排水用開口部１０の上部から前述の室内側空間Ａに逃がすので、その中空部４ａの気圧で雨水溜め部１１に溜った雨水が室内側にしぶきにくい。 Therefore, rainwater or the like that has entered the indoor side of the shoji 5 during strong wind and rain accumulates in the rainwater reservoir 11 on the upper surface 3 a of the lower frame 3.
Rainwater or the like collected in the rainwater reservoir 11 flows out from the lower portion of the drainage opening 10 into the hollow portion 4a of the vertical frame 4 and is drained from the hollow portion 4a to the outdoor side.
Further, even if the air pressure in the hollow portion 4a increases during strong wind and rain, the air pressure is immediately released from the upper part of the drainage opening 10 to the indoor space A, so that it accumulates in the rain water reservoir 11 at the air pressure of the hollow portion 4a. Rain water is difficult to spray indoors.

この実施の形態では、外障子５ｂの戸当り框８が当接する左右一方の縦枠４に排水用開口部１０が形成してある。
前記下枠３の上面３ａにおける外障子５ｂよりも室内側部に雨水が溜り、その雨水が排水用開口部１０から中空部４ａに流出する。
また、下枠３は中空部３ｃを有し、この中空部３ｃが縦枠４の中空部４ａと連通し、下枠３の室外側部に排水孔１２が形成してあるから、縦枠４の中空部４ａに流出した雨水等は下枠３の中空部３ｃに流れ込み、排水孔１２から室外側に排水される。
例えば、図４に示すように下枠３の長手方向端面３ｄが縦枠４の内面４ｂに突き当てて連結され、縦枠４の中空部４ａの下部を蓋１３等で閉塞し、連通孔１４を形成して縦枠４の中空部４ａの下部寄りを下枠３の中空部３ｃに連通する。 In this embodiment, the drainage opening 10 is formed in one of the left and right vertical frames 4 with which the door stoppers 8 of the external shoji 5b abut.
Rainwater accumulates on the indoor side of the upper surface 3a of the lower frame 3 with respect to the shroud 5b, and the rainwater flows out from the drain opening 10 into the hollow portion 4a.
The lower frame 3 has a hollow portion 3c. The hollow portion 3c communicates with the hollow portion 4a of the vertical frame 4, and the drain hole 12 is formed in the outdoor portion of the lower frame 3. Rainwater or the like that has flowed into the hollow portion 4a flows into the hollow portion 3c of the lower frame 3 and is drained from the drain hole 12 to the outdoor side.
For example, as shown in FIG. 4, the longitudinal end surface 3 d of the lower frame 3 is abutted against and connected to the inner surface 4 b of the vertical frame 4, and the lower portion of the hollow portion 4 a of the vertical frame 4 is closed with a lid 13 or the like. The lower portion of the hollow portion 4 a of the vertical frame 4 is communicated with the hollow portion 3 c of the lower frame 3.

前記排水用開口部１０はカバー体２０で覆われている。
このカバー体２０は、下枠３の上面３ａにおける雨水溜め部１１を形成する部分に、縦枠４の内面４ｂに接するように取付けてあり、前記排水用開口部１０を覆って目視されないようにしてある。
前記カバー体２０の上面２０ａには空気抜き孔部２１が形成され、この空気抜き孔部２１は前述の最大水位Ｈよりも高い位置で、排水用開口部１０の上部（空気抜き部）を室内側空間Ａに連通している。
これによって、縦枠４の中空部４ａ内の気圧が排水用開口部１０の上部から空気抜き孔部２１を通って室内側空間Ａに逃げるので、雨水溜め部１１に溜った雨水等が室内側にしぶくことがより低減する。 The drain opening 10 is covered with a cover body 20.
The cover body 20 is attached to a portion of the upper surface 3a of the lower frame 3 where the rain water reservoir 11 is formed so as to be in contact with the inner surface 4b of the vertical frame 4, and covers the drainage opening 10 so that it cannot be seen. It is.
An air vent hole 21 is formed in the upper surface 20a of the cover body 20, and the air vent hole 21 is located at a position higher than the above-mentioned maximum water level H, and the upper part (air vent part) of the drainage opening 10 is located in the indoor space A. Communicating with
As a result, the air pressure in the hollow portion 4a of the vertical frame 4 escapes from the upper portion of the drainage opening 10 through the air vent hole 21 to the indoor space A, so that rainwater and the like accumulated in the rainwater reservoir 11 enter the indoor side. Splashing is further reduced.

前記カバー体２０の形状を図３、図４、図５に基づいて説明するが、これに限ることはない。
上面板２２と一端板２３と室内側縦板２４と中間縦板２５で下面と他端面と室外側面が開口したほぼ箱形状で、その上面板２２の縦枠４の室内面４ｂに接する端面が切欠きされ、その切欠部２２ａと縦枠４の内面４ｂによって前述の空気抜き孔部２１を形成している。
そして、中間縦板２５が下枠３の内下レール１５の室外側面に接し、かつ上面３ａに載置するように取付けられる。
このようであるから、縦枠４の中空部４ａ内の気圧は、その縦枠４の内面４ｂに沿って室内側空間Ａに逃げるので、前述の雨水溜め部１１に溜った雨水等が室内側にしぶくことがより一層低減する。 Although the shape of the said cover body 20 is demonstrated based on FIG.3, FIG.4, FIG.5, it does not restrict to this.
The upper surface plate 22, the one end plate 23, the indoor vertical plate 24, and the intermediate vertical plate 25 are substantially box-shaped with the lower surface, the other end surface, and the outdoor surface open, and the end surface of the upper surface plate 22 that contacts the indoor surface 4 b of the vertical frame 4. The above-described air vent hole 21 is formed by the notch 22 a and the inner surface 4 b of the vertical frame 4.
The intermediate vertical plate 25 is attached so as to be in contact with the outdoor side surface of the inner and lower rails 15 of the lower frame 3 and to be placed on the upper surface 3a.
Thus, the atmospheric pressure in the hollow portion 4a of the vertical frame 4 escapes to the indoor space A along the inner surface 4b of the vertical frame 4, so that the rainwater or the like accumulated in the rainwater reservoir 11 is on the indoor side. The spraying is further reduced.

前記上面板２２は階段形状に折り曲げてあり、その高部２２ｂが縦枠４の内面４ｂにおける排水用開口１０よりも上方位置に接し、低部２２ｃが最大水位Ｈとほぼ同一高さである。なお、この高部２２ｂに孔を形成して空気抜き孔部２１としても良い。
前記内障子５ａを開放するとカバー体２０の一端板２３に当接して内障子５ａの召合せ框が一方の縦枠４の内面４ｂに衝突しないようにしてある。
つまり、カバー体２０はクレセントストッパーを兼用している。
前記カバー体２０は図５に示すように、上面板２２の高部２２ｂ寄りの室外側部に室外側縦板２６を備えている。 The upper surface plate 22 is bent in a staircase shape, and a high portion 22 b thereof is in contact with a position above the drainage opening 10 on the inner surface 4 b of the vertical frame 4, and a low portion 22 c is substantially the same height as the maximum water level H. Note that a hole may be formed in the high portion 22b to form the air vent hole portion 21.
When the inner shroud 5a is opened, it comes into contact with one end plate 23 of the cover body 20 so that the summoning hook of the inner shroud 5a does not collide with the inner surface 4b of one vertical frame 4.
That is, the cover body 20 also serves as a crescent stopper.
As shown in FIG. 5, the cover body 20 includes an outdoor vertical plate 26 on the outdoor side near the high portion 22 b of the top plate 22.

この実施の形態では、上枠２、下枠３、縦枠４が一体形状であるが、複数の枠部材で構成しても良い。
例えば、図６と図７に示すように、外側枠部材３０と内側枠部材３１をビス３２で連結して中空部２ａ，３ｃ，４ａを有する上枠２、下枠３、縦枠４とする。
そして、各外側枠部材３０をブラケット３３と固着具３４で建物躯体３５のサッシ取付開口部３６に取付ける。
前記下枠３の外側枠部材３０に排水孔１２を形成する。
前記縦枠４の内側枠部材３１に排水用開口部１０を形成し、前記下枠３の内側枠部材３１にカバー体２０を取付ける。 In this embodiment, the upper frame 2, the lower frame 3, and the vertical frame 4 are integrally formed, but may be configured by a plurality of frame members.
For example, as shown in FIGS. 6 and 7, the outer frame member 30 and the inner frame member 31 are connected by screws 32 to form an upper frame 2, a lower frame 3, and a vertical frame 4 having hollow portions 2a, 3c, 4a. .
Then, each outer frame member 30 is attached to the sash attachment opening 36 of the building frame 35 with the bracket 33 and the fixing tool 34.
A drain hole 12 is formed in the outer frame member 30 of the lower frame 3.
The drainage opening 10 is formed in the inner frame member 31 of the vertical frame 4, and the cover body 20 is attached to the inner frame member 31 of the lower frame 3.

このようにすれば、サッシ枠１を建物躯体３５に取付けた状態で、ビス３２を室外側から弛めることで、各枠の内側枠部材３１を取り外しできるので、その各内側枠部材３１を交換することが可能である。 By doing so, the inner frame member 31 of each frame can be removed by loosening the screws 32 from the outdoor side with the sash frame 1 attached to the building housing 35, so that each inner frame member 31 is replaced. It is possible.
