Description

【０００１】
本発明は、ルーバー窓（ガラリを含む）に関するものであり、特に、開閉する羽根板が風圧により自動的に開閉するような自然換気構造に好適なルーバー窓に関するものである。
【発明が属する技術分野】
【０００２】
【従来の技術】
一般的に、建物に適用されるルーバー窓は、平時は風を取り入れ、風が強い時などには閉鎖するようにして使用するものである。
このようなルーバー窓は、従来、その気密・水密性を確保するために、縦枠と可動羽根板との間にモヘヤを付設する構造や、例えば、特許文献１に示されるように、枠体と可動羽根板との間にシール装置が採用されているものがある。前記モヘヤはブラシ(毛)のようなものなので硝子（羽根板）の動きで変形しにくく、ある程度の水密が保てるが、高い水密、気密性能はえられず、ルーバー窓の使用箇所（場所）がかぎられるという不具合があった。また、特許文献２に示されるように、風圧により羽根板が自然に開閉するルーパー窓が示されているが、水密、気密機能の向上までは解決課題とはなっていない。

【０００９】
【発明の実施の形態】
以下、本発明の実施形態を説明する。図１は、本実施形態のルーバー窓の正面図、図２は図１I−I線のルーバー窓（給気型）の概略断面図、図３は同ルーバー窓の羽根板が閉止状態の気密部の部分説明図、図４は同ルーバー窓の羽根板が開状態の気密部の部分説明図、図５は同気密部のタイト材のホルダの進退作動説明図、図６は同気密部のホルダの進退作動の別例の説明図、図７は同気密部のホルダの進退作動の更に別例の説明図、図８は同ルーバー窓の羽根板開閉制御のための錘の配置状態を示す説明図、図９はルーバー窓の羽根板開閉制御のための錘の配置状態を示す別例の説明図、図１０は同ルーバー窓の羽根板開閉制御のための錘の配置状態を示す更に別例の説明図、図１１は同ルーバー窓の羽根板の説明図、図１２は図２に相当する図で、別形態のルーバー窓（排気型）の羽根板の概略説明図である。
なお、室内換気には、人工換気と自然換気とがあり、自然換気には、室内外の温度差による空気密度の差が原動力になる重力換気と、建物の外壁に加わる風圧が原動力になる風力換気に大別される。重力換気とは、重い外気は下方から室内に流入し、室内の軽い空気は上方から流出して換気が行われるものを言う。風力換気とは、風が建物に当ると風上側の壁面には正圧（押込む力）が生じ、風下側では負圧（吸出す力）が生じることによって換気が行われるものを言う。本発明は、これらのいずれの換気の場合にも適用が可能なルーバー窓１０に関するものである。
【００１０】
（全体構成）
図１は、本発明に係る実施形態のルーバー窓１０の正面図であり、建物躯体１の壁面に取り付けられる。該ルーバー窓１０は縦枠１１と横枠１２とからなる方形状の枠体内に配置される複数枚の羽根板３０が水平な軸を中心に回動揺動可能に軸支されている。本実施形態では、室外の空気の流れ圧（風）により開閉して室内に空気を取り入れる給気型のルーバー窓１０を構成している。
【００１１】
（ルーバー窓１０）
ルーバー窓１０の羽根板３０は、本実施形態においては、図１に示すように、複数枚の略横長長方形状のガラス板からなり、図２に示す状態においては、室外側（外部）から室内側への空気の流れ（風）により開状態となっている。しかし、室外の空気の流れ（風）が無風又は所定速度以下においては、重力によりその傾斜角度が、鉛直方向に近い下垂姿勢となり閉止状態となる（図１１及び図２の破線参照）。この閉止状態においては、下位置の羽根板の上縁部３０ａは、その上位置の羽根板の下縁部３０ｂと当接状態となっている。
【００１２】
上記羽根板３０群は、図２等に示されるように、支持軸１３に支持されており、該支持軸１３は縦枠１１の水平孔に軸支されている。支持軸は、羽根板の開閉に伴う水平回転の摩擦を極力抑制するために、ベアリング等の軸受けを介して縦枠に設置されることが望ましい。そして、図３，４に示すように、上記羽根板３０の左右の両側端部３０ｃの近傍の縦枠１１にはタイト材１５のホルダ１４及び該ホルダ１４に保持されているタイト材１５が移動可能に配置され、羽根板３０が閉状態では、図３に示すように、タイト材１５が羽根板の側縁３０ｃ側に前進して当接・密着する。また、羽根板３０が開状態では、図４に示すように、タイト材１５が羽根板の側縁部３０ｃから離れた位置に後退し、縦枠の開口部内に収納されるように構成されている。この構成により、羽根板３０とタイト材１０の間には隙間ができ、羽根板３０は風の流れにより滑らかに揺動する。
【００１３】
（規制片２０）
また、図３〜図５に示すように、上記ホルダ１４の室外側には、規制片２０が取り付けられており、タイト材１５がホルダ１４と共に羽根板３０の側縁部３０ｃ側に前進すると、羽根板３０の支持軸１３の室外側で羽根板３０を閉める方向に押さえつけると共に、羽根板３０が完全に閉まった状態においては、羽根板３０を閉状態にロックすることになる。即ち、該規制片２０は、羽根板３０の開き角度を規制するストッパ機能を有する。また、ホルダ１４に規制片２０を取り付けたことで、タイト材１５と羽根板３０の閉まりが連動するが、規制片２０をホルダ１４とは別に設け、互いに独立的に作動させることも可能である。
また、規制片２０は羽根板３０に当接するロック部２２の形を羽根板ごとに変えることで、羽根板３０ごとに、又は、部分的に揺動範囲を変えたり、そろえたりすることができる。又、ホルダ１４の室内側に規制片２０を設け、該規制片２０を羽根板３０の支持軸１３の室内側に当てて、羽根板３０を閉める方向に押さえることもできる。また、規制片２０の羽根板３０との当接部は、羽根板３０が当接する際の、衝撃を吸収する緩衝手段を設けることが好ましい。風が強い場合等には大きな衝撃力や音が生じるので、窓の故障の原因や騒音の低減を図るためである。
【００１４】
（タイト材１５）
上記タイト材１５について説明すると、タイト材１５は、ゴム、合成樹脂等の弾性素材からなり、図３〜図５に示すように、水平断面略方形状で縦枠１１の長さより若干短く形成され、その幅は、羽根板３０の側縁部３０ｃに当接したとき、側縁部３０ｃの全幅にわたって、当接が可能となるような幅・長さとすることが望ましい。
また、上記タイト材１５はホルダ１４に保持されているが、ホルダ１４は、水平断面が図３〜図５に示すように略コ字型に形成され、タイト材１５の上下の全長にわたって保持している。また、ホルダ１４の底部（裏面側）の上下位置の近傍には、図５に示すように、円筒状のネジ受け部１６が一体的に水平に固定されており、各ネジ受け部１６の内面孔部には雌ネジが形成されている。
また、上記タイト材１５は左右縦枠１１の両方とも可動（進退可能）でなく、羽根板３０が水平に多少動くものであれば、片方が固定であっても良い。タイト材１５は気密・水密材でもあり、形状は方形状に限らず、円弧状、ヒレを突出させたもの等でも可能である。
【００１５】
（進退駆動）
一方、縦枠１１内の上下位置には、図３，４に示すように、ネジ回転ホイール１８がチエーン・ベルト等により共動的に回転可能に軸支され、該各軸には、進退ネジ（雄ネジ）１７が連動するように連結されている。また、両ネジ回転ホイール１８を共動的に回転させるために、連動部材１９が掛け渡され（図２参照）、上下位置の進退ネジ１７を同一回転数で回転させる。そして、上記進退ネジ１７は前記各ネジ受け部１６に螺合しており、進退ネジ１７の回転により、ホルダ１４が水平移動することになる。
【００１６】
具体的には、風圧により羽根板３０が開方向に回転すると、該羽根板３０の回転により、進退ネジ１７が回転し、該進退ネジ１７の回転により、ホルダ１４が移動して、羽根板３０の側縁部３０ｃに当接状態にあるタイト材１５を、前記側縁部３０ｃから離れる方向に移動させる。そうすると、規制片２０のロックが解除されると同時に、タイト材１５が縦枠１１内に格納される。
【００１７】
また、風圧が所定値以下になると、又は、風の向きが変わると、羽根板３０が閉方向に回転し、該羽根板３０の回転により、進退ネジ１７が反対方向に回転し、該進退ネジ１７の回転により、ホルダ１４が移動して、羽根板３０の側縁部３０ｃから離れた状態にあるタイト材１５を、前記側縁部３０ｃに当接して密着する方向に移動させる。
【００１８】
なお、本実施形態は、風圧により羽根板３０が開閉するタイプのルーバー窓について説明しているが、前記構成に加えて、又は、手動開閉タイプのルーバー窓において、規制片２０とタイト材１５がハンドル６０により、縦枠１１内に配置されている歯車等の組合せによるハンドル連動部６１を介して同時に動くようにして、羽根板３０の閉鎖と水密・気密確保を同時に行なうようにすることも可能である。
【００１９】
また、進退ネジ１７の別実施の形態として、図６に示すように、互いに逆方向にネジ部が形成された進退ネジ１７ａ，１７ｂに、ホルダ１４の底部（裏面側）の縦枠に設けた孔へ挿入されるスライド棒部１６ａと２本の連結棒１６ｂをヒンジでそれぞれ連結させて、ホルダ１４を進退させてもよい。また、図７に示すように、ホルダ１４の背面の上下に押し棒７０を水平に付設し、バネ受け７１と縦枠１１との間にバネ７２を介装し、作動棒７３に付設したカム７４によって、タイト材１５を進退させてもよい。
【００２０】
（錘５０）
また、図８に示すように、手動開閉タイプのルーバー窓において、羽根板３０を統一的に開閉するためのプーリ１９ａに掛け渡したベルト１９に錘５０を取り付けることによって、羽根板３０の回動を規制することが可能である。なお、室外の空気の流れ圧によって羽根板３０が自動的に開閉するタイプのルーバー窓において、錘部材の支持角や揺動羽根板３０を偏心させて風により開閉するように重心を調整するものでもよく、図９，１０に示すように、各羽根板３０の側縁部３０ｃの両方又は片方をその回転軸部から離して一本の板体５１により連結させてもよい。また、全体の羽根板３０の回動を規制することも可能である。更に、板体を錘とすることも可能であり、板体を軸に対して上下左右に移動可能とすることで、羽根板３０の重心の微調整が可能となる。また、板体（錘）は１本でも２本でも可能である。
【００２１】
また、羽根板の錘を羽根板３０の上横部材（フレーム）とすることにより、格子のような作用によって、防犯性を持たすことが出来る。また、錘５０は羽根板３０の両端ばかりでなく片方だけでも可能である。
また、図８に示すように、風圧により羽根板３０が開閉するタイプのルーバー窓においては、外から見えないように縦枠内の各羽根板３０の回転軸（支持軸１３）の端部に羽根板３０とおなじに動く羽根板連動ホイール(プーリー)４５を設け、上下複数の羽根板連動ホイール（プーリー）４５にベルト４０を掛け渡し、羽根板３０を連動させることで羽根板３０の動きを統一的に動かすようにすることもできる。
【００２２】
その際、ベルト４０に錘材５０をつけることで、個々の羽根板３０ごとに錘を設け、各羽根板３０ごとの重心をひとつひとつ調整する必要はなくなり、連動する羽根板全てに対して風圧による羽根板３０の動きやすさ、軽さ、重さを調整することができる。
また、縦枠内の各羽根板の回転軸（支持軸）の端部に羽根板とおなじに動くウェイト調整棒４５を設け、上下のウェイト調整棒４５に連結棒５１をつなげても良い（図９、図１０）連結することで、羽根板の動きを統一することができ、又、個々の羽根板ごとでなく、連動する羽板板全てに対して一度に重心の調整ができる。連結棒５１はそれ自体が錘材でもよく、又、錘材を取り付けられるようにしても良い。
【００２３】
更に、連結棒５１又は錘材の重さを変えることで羽根板３０の動きやすさを調整できる。又、図１０（ｂ）に示すように、連結棒（錘材）５１、ウェイト調整棒４５に長溝５１aを設けるか、それぞれの長さ方向に多数の孔を開け、連結棒（錘材）５１、ウェイト調整棒４５の任意の孔をヒンジで回動自在に連結するようにして、垂直方向、水平方向にも羽根板に対しては、巾方向にも、巾方向の垂直方向にも錘の位置を移動できるようにすることで回転軸からの錘の距離を変え、風圧による羽根板３０の動きやすさを調整することもできる。連結棒（錘材）５１は１本でもいいが２本でも良い、２本の場合それぞれが錘の位置を移動することでより重心の位置の微調整が可能となる。
【００２４】
また、少なくとも支持軸の室内外どちらか一方に錘を設置することによって、揺動自在に取付けられた羽根板の水平回転軸(支持軸)で分割される面を不均等にすることにより、この回転軸を中心とした羽根板の一方の重心に係る回転モーメントと羽根板の他方の重心に係る回転モーメントとがほぼ釣り合う位置に設けられ、自然風が吹いてきた場合や内外の気圧差がある場合等によって障子部を回動させる力を生じさせて開放又は閉塞状態することができる。また、羽根板に対する重りの相対位置を変化させることで揺動、開閉動作の応答を高めたり、低くしたりすることになる。また、無風時の静止状態と風が吹いてきた状態との動作の応答を高めれば、微弱な風の風量や方向が変化する毎に、開閉動作を行うことができる。
【００２５】
（羽根板３０）
更に、図１１に示すように、羽根板３０の互いに閉状態時の当接部となる上縁部３０ａと下縁部３０ｂの少なくともいずれかに、切欠き部３２を所定幅だけ形成し、該切欠き部３２にタイト材３１を設けることにより、羽根板閉状態時の気密性を一層向上させることができる。また、羽根板３０の最上部及び最下部は上下枠に設けられているタイト材と当接する。なお、羽根板３０が硝子で構成される場合に、一枚ごとの上下に金属フレームを設けると防犯性が向上する。また、羽根板の材質において、実施例ではガラスの例を示したが、アルミ合金、その他の軽金属、合成樹脂製でも良い。
【００２６】
（その他）
上記実施の形態においては、外部正面から風を受けた時に羽根板３０が開く給気型（室内からの風で閉まる）のルーバー窓で説明したが、この発明は、図１２に示すように、無風又は窓の内側の気圧が外側の気圧よりも高い場合に予め定められた角度で開放させ、外部正面から風を受けた時に閉まる排気型（室内からの風で開く）のルーバー窓に適用しても良い。
尚、給気型のルーバーにおいては室内側からの風を受けた時（負圧を利用し）羽根板が閉鎖状態となり、無風の時、室内の気圧と室外の気圧差がない場合、室内の気圧が室外の気圧よりも低い場合、室外からの風を受けた時は羽根板が開状態となるルーバー窓もある。これらの組合せで自然風による正圧、負圧、室内外の気圧差等を有効に利用して室内の自然換気効果が高まる。
【００２７】
【発明の効果】
上記記載のように、本発明によれば、ルーバー窓において羽根板群と縦枠との間の気密・水密性等のシール効果を向上させ、ルーバー窓の用途範囲、例えば、高所でも使用が可能となる。また、羽根板の揺動・開閉・ロック等も、タイト材の移動に付随させて、或いは、独立的に行わせることが可能である。

There are two types of indoor ventilation: artificial ventilation and natural ventilation.Natural ventilation includes gravity ventilation, which is driven by the difference in air density due to temperature differences between the room and outside, and wind power, which is driven by wind pressure applied to the outer walls of the building. Broadly classified as ventilation. Gravity ventilation refers to ventilation in which heavy outside air flows into the room from below and light air in the room flows out from above. Wind power ventilation means that when a wind hits a building, a positive pressure (pressing force) is generated on the wall on the windward side, and a negative pressure (sucking force) is generated on the leeward side to perform ventilation.

[0010]
(overall structure)
FIG. 1 is a front view of a louver window 10 according to an embodiment of the present invention, which is attached to a wall surface of a building frame 1. The louver window 10 has a plurality of blades 30 disposed in a rectangular frame body including a vertical frame 11 and a horizontal frame 12 supported by a pivotable pivotal movement about a horizontal axis. In the present embodiment, an air supply type louver window 10 that opens and closes by the flow pressure (wind) of outdoor air to take air into the room is configured.
[0011]
(Louver window 10)
In the present embodiment, the blade plate 30 of the louver window 10 is composed of a plurality of substantially horizontally elongated rectangular glass plates as shown in FIG. 1, and in the state shown in FIG. It is opened by the flow of air (wind) to the inside. However, when the flow (wind) of the outdoor air is no wind or a predetermined speed or less, the inclination angle becomes a vertical posture close to the vertical direction due to gravity, and the state is closed (see broken lines in FIGS. 11 and 2). In the closed state, the upper edge 30a of the lower position of the blade plate is in contact with the lower edge 30b of the upper position of the blade plate.
[0012]
As shown in FIG. 2 and the like, the blade group 30 is supported by a support shaft 13, which is supported by a horizontal hole of the vertical frame 11. The support shaft is desirably installed on a vertical frame via a bearing such as a bearing in order to minimize friction in horizontal rotation caused by opening and closing of the blade plate. As shown in FIGS. 3 and 4, the holder 14 of the tight material 15 and the tight material 15 held by the holder 14 move to the vertical frame 11 near the left and right end portions 30 c of the wing plate 30. As shown in FIG. 3, the tight material 15 advances toward the side edge 30 c of the blade plate and abuts and adheres when the blade plate 30 is closed and the blade plate 30 is closed. Further, when the slat 30 is in the open state, as shown in FIG. 4, the tight material 15 is retracted to a position away from the side edge 30c of the slat, and is stored in the opening of the vertical frame. I have. With this configuration, a gap is formed between the blade plate 30 and the tight material 10, and the blade plate 30 swings smoothly by the flow of wind.
[0013]

(Male screw) 17 are connected so as to interlock. Further, in order to rotate the two screw rotating wheels 18 cooperatively, an interlocking member 19 is put over (see FIG. 2), and the vertically moving screw 17 is rotated at the same rotation speed. The forward / backward screws 17 are screwed into the respective screw receiving portions 16, and the holder 14 moves horizontally by the rotation of the forward / backward screws 17.
[0016]
Specifically, when the blade plate 30 rotates in the opening direction due to wind pressure, the rotation of the blade plate 30 rotates the advance / retreat screw 17, and the rotation of the advance / retreat screw 17 causes the holder 14 to move. The tight material 15 in contact with the side edge 30c is moved in a direction away from the side edge 30c. Then, the lock of the restriction piece 20 is released, and at the same time, the tight material 15 is stored in the vertical frame 11.
[0017]
Further, when the wind pressure becomes equal to or less than a predetermined value, or when the direction of the wind changes, the blade plate 30 rotates in the closing direction, and the rotation of the blade plate 30 causes the advance / retreat screw 17 to rotate in the opposite direction. The rotation of 17 moves the holder 14 to move the tight material 15 that is separated from the side edge 30c of the slat 30 in a direction in which it comes into close contact with the side edge 30c.
[0018]
In the present embodiment, the louver window of the type in which the blade plate 30 is opened and closed by the wind pressure is described, but in addition to the above configuration, or in the louver window of the manually opened and closed type, the restricting piece 20 and the tight material 15 are provided.

In addition, as shown in FIG. 8, in the louver window of the manual opening / closing type, the weight 50 is attached to the belt 19 which is stretched over the pulley 19a for opening and closing the blade plate 30 in a unified manner. Can be regulated. In a louver window of a type in which the blade plate 30 is automatically opened and closed by the flow pressure of the outdoor air, the louver window adjusts the supporting angle of the weight member and the center of gravity so that the swing blade plate 30 is eccentrically opened and closed by the wind. Alternatively, as shown in FIGS. 9 and 10, both or one of the side edge portions 30 c of each blade plate 30 may be separated by a single plate body 51 away from the rotation shaft portion. Further, it is also possible to regulate the rotation of the entire blade plate 30. Further, the plate body can be a weight, and the plate body can be moved up, down, left and right with respect to the axis, so that the center of gravity of the blade plate 30 can be finely adjusted. The number of plate bodies (weights) may be one or two.
[0021]
In addition, by using the weight of the wing plate as the upper horizontal member (frame) of the wing plate 30, it is possible to have a crime prevention property by an action like a lattice. Further, the weight 50 can be formed not only at both ends but also at one end of the blade plate 30.
As shown in FIG. 8, in a louver window of a type in which the blade plate 30 is opened and closed by wind pressure, the end of the rotation shaft (support shaft 13) of each blade plate 30 in the vertical frame is hidden from the outside. A slat-plate interlocking wheel (pulley) 45 that moves in the same manner as the slats 30 is provided. It can also be operated in a unified way.
[0022]
At this time, by attaching the weight member 50 to the belt 40, it is not necessary to provide a weight for each of the blade plates 30 and adjust the center of gravity of each of the blade plates 30 one by one. The ease of movement, lightness, and weight of the slats 30 can be adjusted.
Further, a weight adjustment rod 45 that moves in the same manner as the blade plate may be provided at the end of the rotation shaft (support shaft) of each blade plate in the vertical frame, and the connecting rod 51 may be connected to the upper and lower weight adjustment rods 45 (FIG. 9, FIG. 10) By connecting, the movements of the blades can be unified, and the center of gravity can be adjusted at once for all the interlocking blades, not for each individual blade. The connecting rod 51 itself may be a weight material, or a weight material may be attached.
[0023]
Further, by changing the weight of the connecting rod 51 or the weight member, the ease of movement of the blade plate 30 can be adjusted. As shown in FIG. 10B, a long groove 51a is provided in the connecting rod (weight member) 51 and the weight adjusting rod 45, or a large number of holes are formed in the respective length directions, and the connecting rod (weight member) 51 is formed. The arbitrary holes of the weight adjustment rod 45 are rotatably connected to each other by a hinge. By allowing the position to move, the distance of the weight from the rotation axis can be changed, and the ease of movement of the blade plate 30 due to wind pressure can also be adjusted. The number of the connecting rods (weight members) 51 may be one or two, and in the case of two, the position of the center of gravity can be finely adjusted by moving the position of each weight.
[0024]
In addition, by installing a weight at least on one of the indoor and outdoor sides of the support shaft, by making the surface divided by the horizontal rotation axis (support shaft) of the swingably mounted blade plate uneven, The rotation moment about one center of gravity of the slats centered on the rotation axis and the rotation moment about the other center of gravity of the slats are provided at positions substantially balanced, and there is a case where natural wind is blowing or a pressure difference between inside and outside. In some cases or the like, a force for rotating the sash part can be generated to open or close the sash part. Further, by changing the relative position of the weight with respect to the blade plate, the response of the swinging and opening / closing operations is increased or decreased. In addition, by increasing the response of the operation between the stationary state when there is no wind and the state where the wind is blowing, the opening / closing operation can be performed every time the amount or direction of the weak wind changes.
[0025]
(Wing plate 30)
Further, as shown in FIG. 11, a notch 32 is formed in a predetermined width in at least one of the upper edge portion 30a and the lower edge portion 30b which are the contact portions of the blade plates 30 in the closed state. By providing the tight material 31 in the notch 32, the airtightness in the closed state of the slats can be further improved. Further, the uppermost and lowermost portions of the blade plate 30 abut on tight materials provided on the upper and lower frames. In the case where the blade plate 30 is made of glass, providing a metal frame above and below each sheet improves security. In the embodiment, the example of the material of the blade is glass, but the material may be aluminum alloy, other light metal, or synthetic resin.

In the above embodiment, the louver window of the air supply type (closed by the wind from the room) in which the blade plate 30 opens when the wind is received from the outside front has been described. However, as shown in FIG. Open to a predetermined angle when there is no wind or when the air pressure inside the window is higher than the outside air pressure. May be.
In the air supply type louver, when the wind from the indoor side is received (using negative pressure), the blades are closed, and when there is no wind, there is no difference between the indoor air pressure and the outdoor air pressure. If the air pressure is lower than the outdoor pressure, there is also a louver window in which the blades are opened when receiving wind from the outdoor. With these combinations, the natural ventilation effect in the room is enhanced by effectively utilizing the positive pressure, the negative pressure, the pressure difference between the room and the outside due to the natural wind, and the like.
