Description

【0001】
【発明の属する技術分野】
本発明は、換気装置付き窓に関する。詳しくは、開閉不能な嵌殺し窓において、または開閉可能な可動式窓であっても開閉することなく、窓枠に設けた換気装置により室内空間を換気可能に構成された換気装置付き窓に関する。
【0002】
【背景技術】
開閉することができない嵌殺し窓において、室外の空気を取り入れ、あるいは室内の空気を排出して、室内空間を換気可能に構成された嵌殺し窓の換気構造が提案されている(例えば、特許文献1、2参照)。特許文献1、2に記載された嵌殺し窓は、いずれも室内外空間に連通した窓枠(下枠、あるいは上枠)の室内側に、換気部材を取り付けて構成されている。この換気部材は、スリット状の通気口を有した室内側部材と、この室内側部材に沿ってスライドし、通気口を開閉可能な可動部材とを備え、つまみ等を操作して可動部材を操作することで、換気状態と非換気状態とを切り替え可能に構成されている。
また、このような換気構造は、嵌殺し窓に限らず、開閉可能な開き窓や辷り出し窓、上げ下げ窓、引違い窓等の可動式窓にも適用可能であって、可動式窓の窓枠に換気構造を設けることで、窓を開閉することなく室内空間の換気を実施することができる。

【0004】
【発明が解決しようとする課題】
しかしながら、特許文献1、2の換気構造では、窓枠に取り付ける換気部材を下枠等の見付け寸法に応じて製造しなければならず、以下のような問題がある。すなわち、窓枠は、取り付ける建物の窓の大きさによって各々異なる寸法で製造されるので、これら様々な寸法を有する窓枠に対応した長さ寸法の換気部材を用意する必要がある。このため、換気部材を製造する際の製造装置が高度になり製造コストが増大するとともに、各種寸法ごとに製造された換気部材を保管、管理しなければならず、部品の管理コストも増大するという問題が生じる。
また、換気部材を共通化して、上記した製造コストや管理コストを低減することも可能であるが、その場合でも、共通化された換気部材の大きさ等に応じて窓枠に加工を施さなければならず、窓枠の製造コストが増大してしまうという問題を招く。
【0005】
本発明の目的は、製造や部品管理のコスト増大を招かずに換気可能に構成することができる換気装置付き窓を提供することにある。
【0006】
【課題を解決するための手段】
本発明の換気装置付き窓は、上枠、下枠、および左右の縦枠を四周枠組みして形成された窓枠を備え、前記上枠、下枠、および縦枠のうち、少なくとも1つには、その見付け方向に沿って室内側に開口するとともに、室外空間と連通された凹溝部が設けられ、前記凹溝部には、室内外空間を連通する換気状態と、連通を遮断する非換気状態とに切り替え操作可能に構成された換気ユニットと、この換気ユニットの見付け方向に隣接して、当該凹溝部の室内側開口部を覆う密閉部材とが嵌合されるとともに、これらの換気ユニットおよび密閉部材と、前記凹溝部とが、着脱可能な係合手段で互いに係合されていることを特徴とする。
【0007】
なお、ここで、見付け方向とは、室内外方向(見込み方向)に直交する方向であって、上枠および下枠においては、それらに沿った水平方向を意味し、縦枠においては、それに沿った垂直方向を意味する。
【0008】
このような本発明によれば、上枠や下枠、縦枠の室内側に形成された凹溝部を室内外空間に連通可能とし、この凹溝部に換気ユニットを取り付けることで、換気ユニットの切り替え操作による室内空間の換気を実施できる。さらに、換気ユニットに隣接して凹溝部に密閉部材を取り付けることで、密閉部材の見付け方向寸法を調節するだけで換気ユニットを隙間なく窓枠に取り付けることができ、窓枠の見付け方向寸法に関わらず、所定の長さ寸法に共通化して製造された換気ユニットを用意しておけばよい。従って、窓枠の大きさに応じて各種寸法を有する換気ユニットを製造する必要がなく、また、換気ユニットの寸法に応じて窓枠に加工を施す必要がないので、コストの増大を招くことなく、窓枠および換気ユニットを製造することができる。
【0009】
また、換気ユニットおよび密閉部材が凹溝部に着脱自在に取り付けられるので、必要に応じて換気ユニットを取り外して、清掃や修理、交換等を実施することができる。すなわち、従来(特許文献1)の換気構造では、換気部材が下枠の長手方向に沿って差し込まれて係合されているので、窓枠を組み立てる際に換気部材を取り付ける必要があるとともに、換気部材を取り外すためには、窓枠を壁等から外し、さらに窓枠を解体しなければならず、取り付けおよび取り外しに手間が掛かるという問題がある。これに対して、本発明の嵌殺し窓では、窓枠の組立後に換気ユニットを取り付けることができるとともに、窓枠を解体することなく換気ユニットを取り外すことができる。
【0010】
この際、本発明の換気装置付き窓では、前記換気ユニットと前記凹溝部の側面との間には、室内空間の気密を保持する気密材が介挿されていることを特徴とする。
このような構成では、換気ユニットと、凹溝部の側面との間に気密材を介挿することで、換気ユニットを非換気状態にすれば、室内外空間の連通が遮断されるため、室外からの雨水等の浸入を防止して水密性を確保できるとともに、室内空間の気密性を確保することができる。
【0011】
さらに、本発明の換気装置付き窓では、前記密閉部材と、前記凹溝部の側面および前記換気ユニットとの間には、室内空間の気密を保持する気密材が介挿されていることを特徴とする。
このような構成では、密閉部材と、凹溝部の側面および換気ユニットとの間に気密材を介挿することで、換気ユニットに隣接した凹溝部においても、水密性や気密性を確保することができる。
【0012】
この際、本発明の換気装置付き窓では、前記係合手段は、前記凹溝部の側面に形成された突出片と、前記換気ユニットおよび密閉部材に形成された係止フックとで構成されていることを特徴とする。
このような構成では、凹溝部側面に形成した突出片と、換気ユニットおよび密閉部材に形成した係止フックとで係合手段を構成したことで、例えば、上枠や下枠、縦枠をアルミ製の押出形材から形成する際に、その長手方向に沿った突出片を容易に形成することができるので、後から係合部材等を取り付けることと比較して、製造にかかる工数を削減でき、製造コストを低減することができる。
【0013】
さらに、本発明の換気装置付き窓では、前記上枠、下枠、および縦枠の見込み寸法は、互いに同一寸法で、かつ所定の規格寸法とされていることを特徴とする。
なお、ここで、所定の規格寸法としては、窓枠の見込み寸法として一般的に採用されている寸法であって、例えば、70mm程度(65〜75mm、いわゆる70見込み)の見込み寸法や、100mm程度(95〜105mm、いわゆる100見込み)の見込み寸法、あるいはそれ以上の見込み寸法などが採用できる。このような構成では、換気ユニットを取り付けた枠材と、換気ユニットを取り付けない枠材とが同一の見込み寸法を有するので、外観を良好にすることができるとともに、窓枠の室内側に取り付けられる膳板や窓台、額縁等の収まりを簡便にでき、これらの施工手間を低減することができる。さらに、窓枠の見込み寸法を所定の規格寸法としたので、換気装置を有していない一般の窓枠と並べて配置しても、互いの見込み寸法を揃えることができ、外観のデザインを統一することができる。
【0014】
【発明の実施の形態】
以下、本発明の各実施形態を図面に基づいて説明する。
なお、第2実施形態以降において、次の第1実施形態で説明する構成部材と同じ構成部材、および同様な機能を有する構成部材には、第1実施形態の構成部材と同じ符号を付し、それらの説明を省略または簡略化する。また、各図においては、主要構成部品の断面を示すハッチングが省略されている。
【0015】
〔第1実施形態〕
本発明の第1実施形態に係る換気装置付き窓について、図1ないし図5に基づいて説明する。
図1および図2は、本実施形態の換気装置付き窓としての嵌殺し窓1を示す横断面図および縦断面図であり、図2は、図1に矢視II−II線で示す断面図である。図3は、嵌殺し窓1の要部を示す縦断面図であり、図1に矢視III−III線で示す断面図である。図4(A)〜(C)は、嵌殺し窓1に取り付けられる換気ユニット10を示す上面図、および二方向から見た側面図である。図5は、嵌殺し窓1の要部を示す縦断面図であり、図1に矢視V−V線で示す断面図である。
【0016】
図1ないし図5において、嵌殺し窓1は、上枠2、下枠3、および左右の縦枠4を四周枠組して形成された窓枠5と、この窓枠5の内部に配置された面材としてのガラスパネル6とを備えて構成されている。ガラスパネル6は、2枚の板ガラスを所定間隔離して対向配置した複層ガラスであって、その四周縁の室内外両面が、気密材であるシール材7を介して上枠2、下枠3、および縦枠4に挟持されて、窓枠5に固定されている。このような窓枠5は、図示しない建物の外壁等に固定されるため、開閉不能になっており、また、窓枠5およびガラスパネル6の間についても、シール材7により室内空間の気密性が保持されている。
なお、ガラスパネル6は、複層ガラスに限らず、単板ガラスや合せガラス等であってもよい。
【0017】
上枠2、下枠3、および縦枠4は、それぞれ見込み方向(図1中、上下方向)の寸法が統一されており、本実施形態においては、約70mm(65〜75mm)の見込み寸法を有する、いわゆる70見込みの窓枠5になっている。そして、上枠2、下枠3、および縦枠4は、それぞれアルミ押出形材製の中空長尺状に形成され、ガラスパネル6を支持する断面略凹字状のパネル支持部2A,3A,4Aを有している。また、窓枠5の室内側には、図示しない膳板や額縁等が取り付けられている。
なお、窓枠5は、70見込みのものに限らず、それより大きな見込み寸法を有したものであってもよい。
【0018】
下枠3のパネル支持部3Aに隣接して室内側には、上方に向かって開口した凹溝部3Bが形成されている。この凹溝部3Bは、下枠3の長手方向に沿って連続し、下枠3の全長に渡って形成されている。凹溝部3Bの底面には、凹溝部3Bの内部と下枠3の中空部3Cとを連通する連通孔3Dが設けられている。また、凹溝部3Bの下方で室外側には、中空部3Cが形成されており、この中空部3Cの室外側には、この中空部3Cと室外空間を連通する連通孔3Eが設けられている。この連通孔3Eは、下枠3の室外側面よりも室内側に入った位置に設けられており、雨水等が容易に浸入しないようになっている。さらに、中空部3Cの底面3Fには、室外側に向かって下がる勾配が設けられており、万一、連通孔3Eから中空部3Cに雨水等が浸入した場合でも、浸入した雨水等が室外側に排出されるようになっている。
【0019】
下枠3の凹溝部3Bには、窓枠5とは別体で製造され、下枠3に沿って長尺な全体略直方体状に形成された換気装置としての換気ユニット10が嵌合されて、取り付けられている。この換気ユニット10の見付け寸法は、下枠3の長さ寸法に比べて短くなっており、換気ユニット10の見付け方向両側における凹溝部3Bには、密閉部材20が嵌合されている。この密閉部材20は、換気ユニット10と縦枠4との間隔距離に応じて、縦枠4内部に貫入するだけの見付け寸法を有しており、縦枠4の内部側面にゴムシート等のシール材を介して密接されている。また、凹溝部3Bの室内外側面下部には、下枠3の長手方向に沿って連続し、水平方向に突出した突出片3Gが形成されている。
【0020】
換気ユニット10は、図3、4に示すように、室内側および凹溝部3Bの底面に向かって開口した箱状の筐体11と、この筐体11の室内側開口部に取り付けられた操作部12および通気部13と、筐体11内部に設けられた作動板14とを備えている。また、筐体11の凹溝部3B底面側には、凹溝部3Bの突出片3Gに対応した係止フック15が形成されており、この係止フック15が突出片3Gに係止されることで、換気ユニット10が凹溝部3Bに係止されるようになっている。さらに、筐体11の凹溝部3B側面に沿った両側面には、気密材であるAT(Air Tight )材16が取り付けられており、このAT材16が凹溝部3B側面に密接するようになっている。また、筐体11の密閉部材20側の両側面には、密閉部材20と密接するAT材17およびシール材18が取り付けられている。
【0021】
換気ユニット10の操作部12には、長手方向に沿って、換気位置と非換気位置との間を移動操作可能な操作つまみ12Aが設けられている。この操作つまみ12Aは、筐体11内部の作動板14と連結されており、操作つまみ12Aを操作することで、作動板14を動作させることができるようになっている。
通気部13は、筐体11の室内側開口部を覆って設けられており、この通気部13には、室内空間と筐体11内部とを連通する複数の通気口13Aがスリット状に形成されている。この通気口13Aの筐体11内部側には、フィルタ13Bが設けられており、室外から虫やほこり等が室内に入らないようになっている。このフィルタ13Bのさらに筐体11内部側に、通気部13全面を覆うだけの大きさを有する作動板14が設けられている。
【0022】
作動板14は、筐体11内部の上部室外側縁に沿って、上下方向に回動可能に取り付けられている。そして、作動板14は、操作つまみ12Aを換気位置に移動させることで、図3中、二点鎖線で示す開状態と、操作つまみ12Aを非換気位置に移動させることで、略水平になる閉状態との間を移動できるようになっている。操作つまみ12Aを換気位置に操作した開状態において、室内側が下方に傾斜した作動板14と通気部13との間に隙間が形成され、この隙間および連通孔3D,3Eを通して室内外空間が連通される。このような室内外空間が連通された換気状態において、室外の外気が室内空間に取り入れられ、あるいは室内の内気が室外空間に排出される、すなわち、室内空間の自然換気が実施されるようになっている。また、操作つまみ12Aを非換気位置に操作した閉状態において、通気部13が作動板14に覆われ、室内外空間の連通が遮断された非換気状態が構成される。
【0023】
密閉部材20は、図5に示すように、下向きに開口した断面略コ字形のアルミ形材製であり、凹溝部3Bの室内側開口部を覆う上面部21と、この上面部21から凹溝部3B底面に向かって延びる2つの延出面部22とを備えて形成されている。上面部21は、換気ユニット10の通気口13Aと互いの上面が略同一レベルになっており、その室内側端縁には、凹溝部3Bの室内側側面上端に係合する段部21Aが形成されている。2つの延出面部22は、それぞれ凹溝部3Bの側面に対向して下方に延び、その先端部には、凹溝部3Bの突出片3Gに係合する係止フック22Aが形成されている。この係止フック22Aは、延出面部22の撓みによる弾性力の作用で突出片3Gに係合するもので、密閉部材20を上方から凹溝部3Bに押し込むだけで係合するようになっている。係止フック22Aが突出片3Gに係止された状態において、延出面部22と凹溝部3Bの側面との間には、隙間空間23が形成されている。また、延出面部22の途中部分には、隙間空間23を連通孔3D,3Eを通して室外空間に連通させる連通孔22Bが設けられている。
【0024】
密閉部材20の上面部21と延出面部22との交差位置外側には、気密材であるAT材24が見付け方向に沿った室内外側に対向して設けられている。これらのAT材24は、凹溝部3Bの室内外側面に密接するとともに、これらAT材24は上面部21よりも見付け方向長さ寸法が若干長く形成されており、AT材24の端部が換気ユニット10のAT材17に押圧力をもって密接されるようになっている。また、換気ユニット10のAT材17の側面に上面部21の端縁が密接されるとともに、上面部21の端縁上側が換気ユニット10のシール材18に覆われるようになっている。以上のように、換気ユニット10のAT材16、および密閉部材20のAT材24が凹溝部3B側面に密接し、密閉部材20のAT材24の端部および上面部21の端縁が換気ユニット10のAT材17に密接することで、凹溝部3B内部に連続した気密ラインが構成される。従って、換気ユニット10の非換気状態において、凹溝部3Bを通した室内外空間の連通が遮断され、室内空間の気密性が確保されるようになっている。
【0025】
以上のような換気ユニット10および密閉部材20は、窓枠5を四周枠組みして製造した後に、下枠3の凹溝部3Bに取り付けられる。すなわち、先ず密閉部材20を凹溝部3BにAT材24を押圧しながら嵌入し、係止フック22Aを突出片3Gに係合させてから両側の縦枠4側にスライドさせて縦枠4の内部側面に密接させる。これに続いて、換気ユニット10を凹溝部3Bの密閉部材20間に嵌入して、AT材17を密閉部材20のAT材24に密接させ、シール材18で密閉部材20の上面部21端縁上側を覆って密接させるとともに、係止フック15を突出片3Gに係合させて取り付ける。以上の手順により、換気ユニット10および密閉部材20が窓枠5に取り付けられることとなる。
なお、窓枠5製造後に密閉部材20を取り付ける手順に限らず、下枠3と縦枠4とを組み立てる際に、密閉部材20を取り付けてもよい。
【0026】
次に、本実施形態の嵌殺し窓1の作用について説明する。
先ず、室内空間を換気する際には、換気ユニット10の操作つまみ12Aを操作して換気位置に移動させる。これにより、操作つまみ12Aに連結された作動板14が通気部13を覆った位置から下方に回動して、開状態となり、通気口13Aおよび連通孔3D,3Eを通して室内外空間が連通される。従って、室外の外気が室内空間に導入され、あるいは室内の内気が室外空間に排出されて、室内空間の換気が実施される。
このような換気状態において、外部の雨水等が連通孔3Eから中空部3Cに浸入したとしても、中空部3Cの上側に設けられた連通孔3Dから凹溝部3Bへは、雨水等が浸入しづらくなっている。さらに、万一、雨水等が凹溝部3Bに浸入したとしても、換気ユニット10の作動板14は室内側下方に傾斜し、通気部13への経路上に位置しているため、この作動板14で阻まれ、雨水等が室内側へ浸入しないようになっている。
【0027】
次に、換気ユニット10の操作つまみ12Aを非換気位置に移動させると、作動板14が通気部13を覆う閉状態に回動して、室内外空間の連通が遮断された非換気状態となる。
このような非換気状態において、外部の風等により連通孔3D,3Eを通して凹溝部3B内部の気圧が上昇すると、換気ユニット10、密閉部材20、および凹溝部3Bの側面の隙間から、外気が室内空間に流入しようとする。しかし、これらの隙間は、AT材16,17,24で塞がれているため、外気が室内空間に流入せず、室内空間の気密性が確保されるようになっている。
【0028】
さらに、非換気状態において凹溝部3B内部に雨水等が浸入した場合、密閉部材20と凹溝部3Bとの隙間から、毛細管現象により雨水等が室内側へ入り込む可能性があるが、密閉部材20の延出面部22と凹溝部3B側面との間に隙間空間23を形成したことで、毛細管現象が生じにくくなり、雨水等の室内側への浸入を防止できるようになっている。また、室外空間の外気圧が室内側と比較して高く、隙間空間23の気圧が外気圧よりも低い場合、凹溝部3B内部に浸入した雨水等が隙間空間23に吸い込まれる可能性があるが、延出面部22に連通孔22Bを設けて隙間空間23を室外空間に連通させたことで、外気圧と隙間空間23の気圧との差を小さくでき、隙間空間23への雨水等の浸入を抑制できるようになっている。
【0029】
このような本実施形態によれば、以下のような効果がある。
(1) 窓枠5の下枠3室内側に形成した凹溝部3Bを連通孔3D,3Eを通して室外空間に連通し、この凹溝部3Bに換気ユニット10を取り付けたので、換気ユニット10の換気状態および非換気状態の切り替え操作によって、開閉不能な嵌殺し窓1であっても、室内空間の換気を実施できる。
【0030】
(2) また、換気ユニット10に隣接して密閉部材20を取り付けることで、密閉部材20の見付け方向寸法を調節するだけで換気ユニット10を隙間なく下枠3の凹溝部3Bに取り付けることができ、窓枠5の見付け方向寸法に関わらず、所定の長さ寸法に共通化して製造された換気ユニット10を用意しておけばよい。従って、窓枠5の大きさに応じて各種寸法を有する換気ユニット10を製造する必要がなく、また、換気ユニット10の寸法に応じて窓枠5に加工を施す必要がないので、コストの増大を招くことなく、窓枠5および換気ユニット10を製造することができる。
【0031】
(3) また、換気ユニット10および密閉部材20が凹溝部3Bに着脱自在に取り付けられるので、必要に応じて換気ユニット10を取り外して、清掃や修理、交換等を実施することができる。すなわち、従来の換気構造では、換気部材の窓枠への取り付けおよび取り外しに手間が掛かるのに対し、本実施形態の嵌殺し窓1では、窓枠5の組立後に換気ユニット10を取り付けることができるとともに、窓枠5を解体することなく換気ユニット10を容易に取り外すことができる。
【0032】
(4) さらに、換気ユニット10を取り付けた下枠3と、換気ユニット10を取り付けない上枠2および縦枠4とが同一の見込み寸法(70見込み)を有するので、嵌殺し窓1の外観を良好にすることができるとともに、窓枠5の室内側に取り付けられる膳板や窓台、額縁等の収まりを簡便にでき、これらの施工手間を低減することができる。
【0033】
(5) また、窓枠5の見込み寸法を所定の規格寸法である70見込みとしたので、換気装置を有していない一般の窓枠と並べて配置しても、互いの見込み寸法を揃えることができ、外観のデザインを統一することができる。
【0034】
(6) また、換気ユニット10と、凹溝部3Bの側面との間にAT材16を介挿し、密閉部材20と、凹溝部3Bの側面との間にAT材24を介挿したので、換気ユニット10を非換気状態にすれば、室内外空間の連通が遮断されるため、室外からの雨水等の浸入を防止して水密性を確保できるとともに、室内空間の気密性を確保することができる。
【0035】
(7) さらに、換気ユニット10の側面にAT材17を設け、このAT材17に密閉部材20のAT材24を密接させるとともに、換気ユニット10のシール材18で密閉部材20の上面部21端縁上側を覆うように構成したので、より一層室内空間の水密性および気密性を向上させることができる。
【0036】
(8) また、密閉部材20の延出面部22と凹溝部3B側面との間に隙間空間23を形成したことで、毛細管現象が生じにくくなり、雨水等の室内側への浸入を防止できるとともに、連通孔22Bで隙間空間23を室外空間に連通させたことで、外気圧と隙間空間23の気圧との差を小さくして、隙間空間23への雨水等の浸入を抑制できるので、室内空間の水密性をさらに向上させることができる。
【0037】
(9) また、凹溝部3B側面に形成した突出片3Gと、換気ユニット10および密閉部材20に形成した係止フック15,22Aとが係合するので、換気ユニット10および密閉部材20を凹溝部3Bに押し込むだけで、容易に取り付けることができる。さらに、アルミ製の押出形材である下枠3を形成する際に、その長手方向(見付け方向)に沿ったヒレ状の突出片3Gを容易に形成することができるので、後から係合部材等を取り付けることと比較して、製造にかかる工数を削減でき、製造コストを低減することができる。
【0038】
〔第2実施形態〕
次に、本発明の第2実施形態に係る換気装置付き窓について、図6に基づいて説明する。
図6は、本実施形態の換気装置付き窓としての開き窓30の要部を示す縦断面図である。
本実施形態の開き窓30は、開閉可能に構成されている点が前述の第1実施形態の嵌殺し窓1と相違し、それ以外の構成は略同様である。以下、相違点について詳しく説明する。
【0039】

BACKGROUND OF THE INVENTION
The present invention relates to a window with a ventilation device. More specifically, the present invention relates to a window with a ventilator configured to ventilate an indoor space by a ventilator provided on a window frame without being opened or closed even in a fitting window that cannot be opened or closed, or even a movable window that can be opened and closed.
[0002]
[Background]
A ventilation structure for a fitting window has been proposed that is configured so that the indoor space can be ventilated by taking in outdoor air or discharging indoor air in a fitting window that cannot be opened and closed (for example, Patent Documents). 1 and 2). The insertion windows described in Patent Documents 1 and 2 are each configured by attaching a ventilation member to the indoor side of a window frame (lower frame or upper frame) communicating with the indoor / outdoor space. This ventilation member includes an indoor side member having a slit-like vent and a movable member that slides along the indoor side member and can open and close the vent, and operates the movable member by operating a knob or the like. By doing, it is comprised so that a ventilation state and a non-ventilation state can be switched.
Further, such a ventilation structure is applicable not only to a closed window but also to a movable window such as an openable / closable opening window, an open window, a raising / lowering window, and a sliding window.

[Problems to be solved by the invention]
However, in the ventilation structure of patent documents 1 and 2, the ventilation member attached to a window frame must be manufactured according to the found dimensions, such as a lower frame, and has the following problems. That is, since the window frame is manufactured with different dimensions depending on the size of the window of the building to be attached, it is necessary to prepare a ventilation member having a length corresponding to the window frame having various dimensions. For this reason, the manufacturing apparatus for manufacturing the ventilation member becomes sophisticated and the manufacturing cost increases, and the ventilation member manufactured for each dimension must be stored and managed, and the management cost of the parts also increases. Problems arise.
In addition, it is possible to reduce the manufacturing cost and management cost described above by using a common ventilation member, but even in that case, the window frame must be processed according to the size of the common ventilation member. In other words, the manufacturing cost of the window frame increases.
[0005]
The objective of this invention is providing the window with a ventilator which can be comprised so that ventilation is possible, without causing the increase in cost of manufacture or parts management.
[0006]
[Means for Solving the Problems]
A window with a ventilator according to the present invention includes a window frame formed by quadrangularly forming an upper frame, a lower frame, and left and right vertical frames, and at least one of the upper frame, the lower frame, and the vertical frame. Is provided with a recessed groove portion that opens to the indoor side along the direction of finding and communicates with the outdoor space, and in the recessed groove portion, a ventilation state that communicates with the indoor and outdoor spaces and a non-ventilated state that blocks communication A ventilation unit configured to be capable of switching to and a sealing member that covers the indoor side opening of the concave groove portion are fitted adjacent to the direction in which the ventilation unit is found. The member and the concave groove are engaged with each other by detachable engaging means.
[0007]
Here, the finding direction is a direction orthogonal to the indoor / outdoor direction (prospective direction), and in the upper frame and the lower frame, means a horizontal direction along them, and in the vertical frame, along it. Means vertical direction.
[0008]
According to the present invention, the groove portion formed on the indoor side of the upper frame, the lower frame, and the vertical frame can be communicated with the indoor / outdoor space, and the ventilation unit is switched by attaching the ventilation unit to the groove portion. The indoor space can be ventilated by operation. In addition, by attaching a sealing member to the concave groove adjacent to the ventilation unit, the ventilation unit can be attached to the window frame without any gaps simply by adjusting the size of the sealing member. Instead, a ventilation unit manufactured in common with a predetermined length may be prepared. Therefore, it is not necessary to manufacture a ventilation unit having various dimensions according to the size of the window frame, and it is not necessary to process the window frame according to the dimension of the ventilation unit, so that the cost is not increased. Window frames and ventilation units can be manufactured.
[0009]
In addition, since the ventilation unit and the sealing member are detachably attached to the concave groove portion, the ventilation unit can be removed as necessary to perform cleaning, repair, replacement, and the like. That is, in the conventional ventilation structure (Patent Document 1), since the ventilation member is inserted and engaged along the longitudinal direction of the lower frame, it is necessary to attach the ventilation member when assembling the window frame. In order to remove the member, the window frame must be removed from the wall or the like, and the window frame must be disassembled. On the other hand, in the fitting window of the present invention, the ventilation unit can be attached after the window frame is assembled, and the ventilation unit can be removed without disassembling the window frame.
[0010]
In this case, the window with a ventilator according to the present invention is characterized in that an airtight member for keeping the airtightness of the indoor space is interposed between the ventilation unit and the side surface of the concave groove portion.
In such a configuration, if the ventilation unit is placed in a non-ventilated state by inserting an air-tight material between the ventilation unit and the side surface of the concave groove portion, communication between the indoor and outdoor spaces is blocked. It is possible to ensure the watertightness by preventing the intrusion of rainwater and the like, and to secure the airtightness of the indoor space.
[0011]
Furthermore, in the window with a ventilator according to the present invention, an airtight member for maintaining airtightness in an indoor space is interposed between the sealing member, a side surface of the concave groove portion, and the ventilation unit. To do.
In such a configuration, watertightness and airtightness can be ensured even in the groove portion adjacent to the ventilation unit by inserting an airtight material between the sealing member, the side surface of the groove portion and the ventilation unit. it can.
[0012]
At this time, in the window with a ventilator according to the present invention, the engaging means is constituted by a protruding piece formed on a side surface of the concave groove portion and a locking hook formed on the ventilation unit and the sealing member. It is characterized by that.
In such a configuration, the engaging means is configured by the projecting piece formed on the side surface of the concave groove portion and the locking hook formed on the ventilation unit and the sealing member. For example, the upper frame, the lower frame, and the vertical frame are made of aluminum. When forming from the extruded shape of the product, it is possible to easily form the protruding piece along the longitudinal direction, so it is possible to reduce the number of man-hours required for manufacturing compared to attaching an engaging member or the like later. The manufacturing cost can be reduced.
[0013]
Furthermore, in the window with a ventilator according to the present invention, the prospective dimensions of the upper frame, the lower frame, and the vertical frame are the same as each other and predetermined standard dimensions.
Here, the predetermined standard dimension is a dimension generally adopted as a prospective dimension of the window frame, for example, a prospective dimension of about 70 mm (65 to 75 mm, so-called 70 prospect), or about 100 mm. A prospective dimension (95 to 105 mm, so-called 100 prospective) or a prospective dimension larger than that can be adopted. In such a configuration, since the frame material with the ventilation unit attached and the frame material without the ventilation unit have the same prospective dimensions, the appearance can be improved and the frame material can be attached to the indoor side of the window frame. It is possible to simplify the fitting of the siding plate, the window sill, the frame, and the like, and to reduce the labor of these constructions. Furthermore, because the expected dimensions of the window frame are set to the specified standard dimensions, even if they are arranged side by side with a general window frame that does not have a ventilation device, the expected dimensions of each other can be aligned, and the appearance design is unified. be able to.

In addition, a communication hole 22B is provided in the middle of the extended surface portion 22 to connect the gap space 23 to the outdoor space through the communication holes 3D and 3E.
[0024]
An AT material 24, which is an airtight material, is provided on the outer side of the intersection between the upper surface portion 21 and the extended surface portion 22 of the sealing member 20 so as to face the outside of the room along the direction of finding. These AT materials 24 are in close contact with the indoor outer surface of the recessed groove portion 3B, and these AT materials 24 are formed to have slightly longer lengths in the direction of finding than the upper surface portion 21, and the end portions of the AT materials 24 are ventilated. The unit 10 is brought into close contact with the AT material 17 with a pressing force. Further, the edge of the upper surface portion 21 is in close contact with the side surface of the AT material 17 of the ventilation unit 10, and the upper edge of the upper surface portion 21 is covered with the sealing material 18 of the ventilation unit 10. As described above, the AT material 16 of the ventilation unit 10 and the AT material 24 of the sealing member 20 are in close contact with the side surface of the recessed groove portion 3B, and the end of the AT material 24 and the edge of the upper surface portion 21 of the sealing member 20 are the ventilation unit. By being in close contact with the ten AT members 17, a continuous airtight line is formed inside the groove 3B. Therefore, in the non-ventilated state of the ventilation unit 10, the communication between the indoor and outdoor spaces through the concave groove portion 3B is blocked, and the airtightness of the indoor space is ensured.
[0025]
The ventilation unit 10 and the sealing member 20 as described above are attached to the recessed groove portion 3 </ b> B of the lower frame 3 after the window frame 5 is manufactured with a four-round frame. That is, first, the sealing member 20 is inserted into the concave groove portion 3B while pressing the AT member 24, the locking hook 22A is engaged with the protruding piece 3G, and then slid to the vertical frame 4 side on both sides to be inside the vertical frame 4. Close to the side. Following this, the ventilation unit 10 is fitted between the sealing members 20 of the recessed groove portion 3B, the AT material 17 is brought into close contact with the AT material 24 of the sealing member 20, and the edge of the upper surface portion 21 of the sealing member 20 is sealed with the sealing material 18. The upper side is covered and brought into close contact, and the locking hook 15 is engaged with and attached to the protruding piece 3G. The ventilation unit 10 and the sealing member 20 are attached to the window frame 5 by the above procedure.
The sealing member 20 may be attached when the lower frame 3 and the vertical frame 4 are assembled without being limited to the procedure of attaching the sealing member 20 after the window frame 5 is manufactured.
[0026]
Next, the effect | action of the insertion window 1 of this embodiment is demonstrated.
First, when ventilating the indoor space, the operation knob 12A of the ventilation unit 10 is operated and moved to the ventilation position. As a result, the operating plate 14 connected to the operation knob 12A rotates downward from the position covering the ventilation portion 13 to be in an open state, and the indoor / outdoor space is communicated through the ventilation port 13A and the communication holes 3D and 3E. . Accordingly, the outdoor air outside the room is introduced into the indoor space, or the indoor air inside the room is discharged into the outdoor space, thereby ventilating the indoor space.
In such a ventilation state, even if external rainwater or the like enters the hollow portion 3C from the communication hole 3E, it is difficult for rainwater or the like to enter the concave groove portion 3B from the communication hole 3D provided on the upper side of the hollow portion 3C. It has become. Furthermore, even if rainwater or the like enters the recessed groove portion 3B, the operation plate 14 of the ventilation unit 10 is inclined downward on the indoor side and is located on the path to the ventilation portion 13, so that the operation plate 14 This prevents rainwater from entering the room.
[0027]
Next, when the operation knob 12A of the ventilation unit 10 is moved to the non-ventilated position, the operation plate 14 is rotated to a closed state covering the ventilation portion 13, and a non-ventilated state in which the communication between the indoor and outdoor spaces is blocked. .
In such a non-ventilated state, when the air pressure inside the recessed groove portion 3B rises through the communication holes 3D and 3E due to the outside wind or the like, the outside air flows into the room from the gaps on the side surfaces of the ventilation unit 10, the sealing member 20, and the recessed groove portion 3B. Try to flow into the space. However, since these gaps are blocked by the AT materials 16, 17, and 24, the outside air does not flow into the indoor space, and the airtightness of the indoor space is ensured.
[0028]
Furthermore, when rainwater or the like enters the concave groove portion 3B in a non-ventilated state, rainwater or the like may enter the indoor side due to a capillary phenomenon from the gap between the sealing member 20 and the concave groove portion 3B. By forming the clearance space 23 between the extended surface portion 22 and the side surface of the recessed groove portion 3B, the capillary phenomenon is less likely to occur, and intrusion of rainwater or the like into the indoor side can be prevented. In addition, when the outdoor air pressure in the outdoor space is higher than the indoor side and the air pressure in the gap space 23 is lower than the outside air pressure, rainwater or the like that has entered the groove 3B may be sucked into the gap space 23. By providing the communication hole 22B in the extended surface portion 22 and communicating the gap space 23 with the outdoor space, the difference between the external pressure and the pressure in the gap space 23 can be reduced, and rainwater or the like can enter the gap space 23. It can be suppressed.
[0029]
According to this embodiment, there are the following effects.
(1) The lower groove 3 of the window frame 5 The concave groove portion 3B formed on the indoor side is communicated with the outdoor space through the communication holes 3D and 3E, and the ventilation unit 10 is attached to the concave groove portion 3B. Further, by the switching operation of the non-ventilated state, the indoor space can be ventilated even if the fitting window 1 cannot be opened and closed.
[0030]
