　換気装置は、室内外に連通する構成を備えるため、使用に伴い羽根や防虫網に塵埃が付着して汚れやすい。しかし、上記従来の換気装置は、羽根が枠体に固定されているためメンテナンスが困難である。 Since the ventilation device has a structure that communicates indoors and outdoors, dust easily adheres to the blades and insect screen as it is used and becomes dirty. However, the conventional ventilation device is difficult to maintain because the blades are fixed to the frame body.
　また、上記従来例の換気装置では、水切り部が室外側に突出しているため、外観意匠性が悪かった。そこで、水切り機能と外観意匠性との両立が望まれていた。 Further, in the above-mentioned conventional ventilation device, the draining portion protrudes to the outside of the room, so that the appearance design is poor. Therefore, it has been desired to achieve both a draining function and an appearance design.
　上記事情を踏まえ、本発明は、メンテナンス作業が容易に行え、かつ、水切り機能と外観意匠性を両立させた換気装置およびこの換気装置を備えるサッシユニットを提供することを目的とする。 Based on the above circumstances, it is an object of the present invention to provide a ventilation device capable of easily performing maintenance work and having both a draining function and an appearance design, and a sash unit provided with this ventilation device.
　本発明の第一の態様に係る換気装置は、建物の開口に取り付けられ、一対の縦枠と、前記一対の縦枠間に架設される一対の横枠とを備える枠体と、前記枠体の幅方向の両端部に設けられる羽根保持部と、前記一対の縦枠間に延設され、前記幅方向の両端部が前記羽根保持部に回動自在に保持されて、前記枠体に形成された開口部を開閉可能に回動し、かつ前記枠体に対して着脱可能である回動羽根と、を備えていることを特徴とする。 The ventilation device according to the first aspect of the present invention includes a frame body which is attached to an opening of a building and includes a pair of vertical frames and a pair of horizontal frames erected between the pair of vertical frames, and the frame body. It is extended between the blade holding portions provided at both ends in the width direction and the pair of vertical frames, and both ends in the width direction are rotatably held by the blade holding portions and formed on the frame body. It is characterized in that it includes a rotating blade that can open and close the opened opening and that can be attached to and detached from the frame.
　この発明によれば、建物の開口に取り付けられる換気装置において、回動羽根が枠体に対して着脱可能に設けられているため、回動羽根を取り外してメンテナンス作業が行える。したがって、メンテナンス作業が容易に行える換気装置を提供できる。 According to the present invention, in the ventilation device attached to the opening of the building, since the rotating blades are detachably provided with respect to the frame body, the rotating blades can be removed for maintenance work. Therefore, it is possible to provide a ventilation device that can easily perform maintenance work.
　本発明の第二の態様は、上記態様に係る換気装置において、前記羽根保持部は、前記一対の縦枠の対向面の少なくとも一方の面に固定され、前記回動羽根を支持する支持部を有する第１保持体と、室内側から着脱可能であり、かつ、前記回動羽根を前記第１保持体と挟持した状態で前記枠体に係止される第２保持体と、を備えてもよい。 A second aspect of the present invention is that in the ventilation device according to the above aspect, the blade holding portion is fixed to at least one surface of the facing surfaces of the pair of vertical frames, and a support portion that supports the rotating blade is provided. Even if it is provided with a first holding body having the first holding body, and a second holding body that is detachable from the indoor side and is locked to the frame body while holding the rotating blade with the first holding body. Good.
　この発明によれば、第２保持体は、室内側から着脱可能であり、羽根保持部は第１保持体と第２保持体とにより回動羽根を回動可能に係合する。この結果、室内側から第２保持体を枠体に対して着脱する操作により、回動羽根が枠体に対して着脱可能であり、メンテナンス作業が容易に行える。 According to the present invention, the second holding body is removable from the indoor side, and the blade holding portion rotatably engages the rotating blades with the first holding body and the second holding body. As a result, the rotating blades can be attached to and detached from the frame by the operation of attaching and detaching the second holding body to and from the frame from the indoor side, and maintenance work can be easily performed.
　本発明の第三の態様は、上記態様に係る換気装置において、前記枠体に前記開口部と連通して室外側に形成された室外側開口部と前記回動羽根との間に前記幅方向に延びて設けられる防虫網を備え、前記防虫網は、前記枠体に対して着脱可能に係合されていてもよい。 A third aspect of the present invention is the width direction between the outdoor opening formed on the outdoor side of the frame body communicating with the opening and the rotating blade in the ventilation device according to the above aspect. The insect repellent net may be detachably engaged with the frame body, and the insect repellent net may be detachably engaged with the frame body.
　この発明によれば、室外側開口部と回動羽根との間に防虫網が設けられているため、回動羽根を開位置にして室内外を換気する際、防虫網により虫や塵等の侵入を防ぐことができる。防虫網が枠体に対して室内側より着脱可能に係合されているため、防虫網の清掃等のメンテナンス作業が容易に行える。 According to the present invention, since an insect net is provided between the outdoor opening and the rotating blade, when the rotating blade is opened to ventilate the inside and outside of the room, the insect net prevents insects, dust, etc. Intrusion can be prevented. Since the insect net is detachably engaged with the frame from the indoor side, maintenance work such as cleaning the insect net can be easily performed.
　本発明の第四の態様は、上記態様に係る換気装置において、前記回動羽根は、前記開口部が所定の開口面積となる位置で回動が停止可能に構成されていてもよい。 A fourth aspect of the present invention is the ventilation device according to the above aspect, wherein the rotating blades may be configured so that rotation can be stopped at a position where the opening has a predetermined opening area.
　この発明によれば、開口部の開口面積が所定面積となる位置で回動羽根の回動が停止できる。したがって、換気量を段階的にコントロール可能であり、使用者の利便性に貢献できる。 According to the present invention, the rotation of the rotating blade can be stopped at a position where the opening area of the opening becomes a predetermined area. Therefore, the ventilation volume can be controlled step by step, which can contribute to the convenience of the user.
　本発明の第五の態様は、上記態様に係る換気装置において、前記回動羽根は、回動時に前記開口部を閉鎖する閉位置側、または前記開口部を最大開放する開位置側に向かって回動するように重心が設定され、前記羽根保持部には、前記閉位置および前記開位置で前記回動羽根の回動を停止するストッパが形成されていてもよい。 A fifth aspect of the present invention is that in the ventilation device according to the above aspect, the rotary blades are directed toward a closed position side that closes the opening at the time of rotation or an open position side that opens the opening to the maximum. The center of gravity is set so as to rotate, and the blade holding portion may be formed with a stopper that stops the rotation of the rotating blade at the closed position and the open position.
　この発明によれば、回動羽根に対して開口部と室外側開口部との間の通気経路を開放する方向または閉鎖する方向に力が加わると、回動羽根自体の荷重バランスにより、回動羽根が閉位置または開位置に向かって回動するように構成されている。さらに、羽根保持部にはストッパが形成されているため、回動羽根の回動を閉位置または開位置で停止できる。したがって、使用者は僅かな力を加える操作により回動羽根を開位置または閉位置に停止でき、回動羽根の開閉操作を簡単に行える。 According to the present invention, when a force is applied to the rotary blade in the direction of opening or closing the ventilation path between the opening and the outdoor opening, the rotary blade itself rotates due to the load balance of the rotary blade itself. The blades are configured to rotate towards a closed or open position.

A through hole 43 is formed in the rotating shaft body 42 and the small arc portion 420.
　一対の側板部４１の対向面４１３間に羽根本体４０が架設されている。図５に示すように、羽根本体４０は、幅方向Ｗに直交する断面形状が翼形状を有する中空部材である。羽根本体４０には、室内Ｉ側に位置して幅方向Ｗに延びる室内端４４と、室外Ｏ側に位置して幅方向Ｗに延びる室外端４５とを備える。羽根本体４０は、側板部４１の円弧部４１１の周方向に離間した３か所で側板部４１に固定されている。具体的には、羽根本体４０は、側板部４１の円弧部４１１の周方向の中間位置に固定される中間固定部４１２と、室外端４５近傍が側板部４１の円弧部４１１の端部に固定される室外側固定部４１３と、室内端４４近傍が側板部４１の円弧部４１１の端部に固定される室内側固定部４１４と、の３か所で側板部４１に固定されている。 The blade main body 40 is erected between the facing surfaces 413 of the pair of side plate portions 41. As shown in FIG. 5, the blade body 40 is a hollow member having a blade shape having a cross-sectional shape orthogonal to the width direction W. The blade main body 40 includes an indoor end 44 located on the indoor I side and extending in the width direction W, and an outdoor end 45 located on the outdoor O side and extending in the width direction W.

The outdoor side fixing portion 413 and the indoor side fixing portion 414 in which the vicinity of the indoor end 44 is fixed to the end of the arc portion 411 of the side plate portion 41 are fixed to the side plate portion 41 at three places.
　回動羽根４の中間固定部４１２における外面には、外方に突出する突起４６が設けられている。突起４６は、回動羽根４の幅方向Ｗに沿って設けられている。回動羽根４の外面は、突起４６から室内側固定部４１４まで曲率半径が大きい平坦部４７が形成されている。 A protrusion 46 projecting outward is provided on the outer surface of the intermediate fixing portion 412 of the rotating blade 4. The protrusion 46 is provided along the width direction W of the rotary blade 4. A flat portion 47 having a large radius of curvature is formed on the outer surface of the rotating blade 4 from the protrusion 46 to the indoor side fixing portion 414.
　回動羽根４は、室外端４５および室内端４４が中間固定部４１２の領域よりも重くなるように重心が設定されている。詳細は後述するが、この構成により回動羽根４の回動時、回動羽根４が室内端４４側あるいは室外端４５側に回動し易くなる。本実施形態では、回動羽根４は樹脂または金属製の一体成型部品または樹脂および金属製の複合部品であり、室外端４５および室内端４４を他の領域よりも肉厚に形成することにより重心が室外端４５および室内端４４に偏在するように構成されている。 The center of gravity of the rotary blade 4 is set so that the outdoor end 45 and the indoor end 44 are heavier than the region of the intermediate fixing portion 412. Although the details will be described later, this configuration makes it easy for the rotary blade 4 to rotate toward the indoor end 44 side or the outdoor end 45 side when the rotary blade 4 rotates. In the present embodiment, the rotary vane 4 is an integrally molded part made of resin or metal or a composite part made of resin and metal, and the center of gravity is formed by forming the outdoor end 45 and the indoor end 44 thicker than other regions. Is unevenly distributed at the outdoor end 45 and the indoor end 44.
　回動羽根４は、室内側開口部９１の開口面積が約半分となる位置でバランスを取るように重心が設定されている。すなわち、室内端４４が室内側開口部９１の高さ方向の略中間部に位置すると、回動羽根４のバランスが取れて均衡状態となり、室内側開口部９１が中間の開口面積で保持される。 The center of gravity of the rotating blade 4 is set so as to balance the opening area of the indoor opening 91 at a position where the opening area is about half. That is, when the indoor end 44 is located substantially in the middle of the indoor opening 91 in the height direction, the rotating blades 4 are balanced and in an equilibrium state, and the indoor opening 91 is held in the intermediate opening area. ..
　防虫網７は、枠体２の室外側開口部９２と前記回動羽根４との間に幅方向Ｗに延びて設けられる。防虫網７は、平面視矩形のメッシュ膜７０の周囲が網枠７１に固定されて構成されている。図５に示すように、網枠７１は、室内Ｉ側に配置される内横枠７３にフック７３１と、把持部７３３と、位置決め片７３２とが形成されている。フック７３１は、内横枠７３の下面から下方に突出して室内Ｉ側に曲折した略Ｌ字型に形成されている。把持部７３３は内横枠７３の上面から上方に突出して形成されている。位置決め片７３２は、内横枠７３の下面から室内Ｉ側に延設される平板状の部分である。 The insect repellent net 7 is provided between the outdoor opening 92 of the frame body 2 and the rotating blade 4 extending in the width direction W. The insect repellent net 7 is configured such that the periphery of the mesh film 70 having a rectangular shape in a plan view is fixed to the net frame 71. As shown in FIG. 5, in the net frame 71, a hook 731, a grip portion 733, and a positioning piece 732 are formed on an inner horizontal frame 73 arranged on the indoor I side. The hook 731 is formed in a substantially L-shape that protrudes downward from the lower surface of the inner horizontal frame 73 and is bent toward the indoor I side. The grip portion 733 is formed so as to project upward from the upper surface of the inner horizontal frame 73. The positioning piece 732 is a flat plate-shaped portion extending from the lower surface of the inner horizontal frame 73 to the indoor I side.
　次に、換気装置１の全体構造および、回動羽根４ならびに防虫網７の着脱方法について図５から図１３を用いて説明する。図６および図７に回動羽根４の回動態様を示し、図１１から図１３に回動羽根４ならびに防虫網７の着脱方法を示す。 Next, the overall structure of the ventilation device 1 and the method of attaching and detaching the rotating blade 4 and the insect screen 7 will be described with reference to FIGS. 5 to 13. 6 and 7 show the rotation mode of the rotary blade 4, and FIGS. 11 to 13 show how to attach / detach the rotary blade 4 and the insect net 7.
　図６に示すように、枠体２において、上枠２３および縦枠２１の室内Ｉ側の端部と、下枠２２の上縁部２２８とにより室内側開口部９１が形成される。縦枠２１の室外Ｏ側の端部と、室外側壁部２３１の下端部と、下枠２２の下支持部２２０の上端部とにより室外側開口部９２が形成される。図５に示すように、室外側開口部９２は、室内側開口部９１よりも低い位置で開口している。室外側開口部９２と室内側開口部９１とは連通しており、室外Ｏ側から室内側に向かって上昇する換気経路Ｃが形成されている。 As shown in FIG. 6, in the frame body 2, the indoor side opening 91 is formed by the ends of the upper frame 23 and the vertical frame 21 on the indoor I side and the upper edge portion 228 of the lower frame 22. The outdoor opening 92 is formed by the outdoor O-side end of the vertical frame 21, the lower end of the outdoor wall 231 and the upper end of the lower support 220 of the lower frame 22. As shown in FIG. 5, the outdoor side opening 92 is opened at a position lower than the indoor side opening 91. The outdoor opening 92 and the indoor opening 91 communicate with each other, and a ventilation path C rising from the outdoor O side toward the indoor side is formed.
　室内側開口部９１と室内側開口部９２との間に防虫網７が換気経路Ｃを横断して取り付けられている。防虫網７の上方に回動羽根４が回動可能に取り付けられている。回動羽根４は手動により回動され、室内側開口部９１の開口が開放または閉鎖される。 An insect net 7 is attached across the ventilation path C between the indoor opening 91 and the indoor opening 92. A rotating blade 4 is rotatably attached above the insect screen 7. The rotary blade 4 is manually rotated to open or close the opening of the indoor opening 91.
　防虫網７は、枠体２に対して着脱可能に係合されている。図５に示すように、防虫網７は、内横枠７３が第１防虫網保持部２２２に係止され、室外Ｏ側に配置される網枠７１の外横枠７２が第２防虫網保持部２３８に載置される。具体的には、第２防虫網保持部２３８の網枠支持台２３６に外横枠７２が載置され、内横枠７３のフック７３１が網係止溝２２４内に挿入され、位置決め片７３２が第１防虫網支持部２２５に当接して載置される。この状態で、把持部７３３とシール材８３との間には隙間が形成され、外横枠７２の室外Ｏ側の面は緩衝材８２に近接配置される。 The insect repellent net 7 is detachably engaged with the frame body 2. As shown in FIG. 5, in the insect net 7, the inner horizontal frame 73 is locked to the first insect net holding portion 222, and the outer horizontal frame 72 of the net frame 71 arranged on the outdoor O side holds the second insect net. It is placed on the part 238. Specifically, the outer horizontal frame 72 is placed on the net frame support base 236 of the second insect repellent net holding portion 238, the hook 731 of the inner horizontal frame 73 is inserted into the net locking groove 224, and the positioning piece 732 is inserted. It is placed in contact with the first insect net support portion 225. In this state, a gap is formed between the grip portion 733 and the sealing material 83, and the surface of the outer horizontal frame 72 on the outdoor O side is arranged close to the cushioning material 82.
　防虫網７を枠体２から取り外すときは、把持部７３３を把持して防虫網７を室外Ｏ側に押すと、緩衝材８２が圧縮されてフック７３１が網係止溝２２４から外れ、その後、把持部７３３を上方に持ち上げると防虫網７を枠体２から取り外せる。一方、防虫網７を枠体２に取り付けるときは、把持部７３３を把持して室内側開口部９１から挿入し、外横枠７２を第２防虫網保持部２３８の防虫網支持部２３６に載置した後、緩衝材８２が圧縮されるまで、防虫網７を室外Ｏ側に押し込む。この状態で把持部７３３を換気ガイド面２２３側に下げると、フック７３１が網係止溝２２４の下側の突出部２２４１上に接触する。その後、把持部７３３の押込みを解除して室内Ｉ側に引くと、フック７３１が網係止溝２２４内に進入し、同時に位置決め片７３２が第１防虫網支持部２２５上に載置され、防虫網７が枠体２に係止される。防虫網７は内横枠７３が第１防虫網保持部２２２に係止され、外横枠７２が緩衝材８２に当接しているため、係止位置が保持される。 When removing the insect repellent net 7 from the frame body 2, when the grip portion 733 is gripped and the insect repellent net 7 is pushed toward the outdoor O side, the cushioning material 82 is compressed and the hook 731 is disengaged from the net locking groove 224, and then The insect screen 7 can be removed from the frame 2 by lifting the grip portion 733 upward. On the other hand, when the insect net 7 is attached to the frame 2, the grip portion 733 is gripped and inserted from the indoor opening 91, and the outer horizontal frame 72 is placed on the insect net support portion 236 of the second insect net holding portion 238. After placing, the insect repellent net 7 is pushed toward the outdoor O side until the cushioning material 82 is compressed. When the grip portion 733 is lowered toward the ventilation guide surface 223 in this state, the hook 731 comes into contact with the protruding portion 2241 on the lower side of the net locking groove 224. After that, when the grip portion 733 is released and pulled toward the room I side, the hook 731 enters the net locking groove 224, and at the same time, the positioning piece 732 is placed on the first insect net support portion 225 to prevent insects. The net 7 is locked to the frame body 2. In the insect repellent net 7, the inner horizontal frame 73 is locked to the first insect repellent net holding portion 222, and the outer horizontal frame 72 is in contact with the cushioning material 82, so that the locked position is held.
　防虫網７は、外横枠７２より内横枠７３が僅かに高くなるように、水平面に対して僅かに傾斜して係止されている。このため、回動羽根４が開位置にあり換気経路Ｃが開放されているとき、室内Ｉ側から目立たないように防虫網７を配置できる。 The insect repellent net 7 is locked with a slight inclination with respect to the horizontal plane so that the inner horizontal frame 73 is slightly higher than the outer horizontal frame 72. Therefore, when the rotating blade 4 is in the open position and the ventilation path C is open, the insect repellent net 7 can be arranged so as not to stand out from the room I side.
　次に、回動羽根４を枠体２に取り付ける方法を説明する。回動羽根４は室内側から着脱操作できる。図１０に示すように、一対の縦枠２１の対向面２１３にそれぞれ第１保持体５がネジで固定されており、室内側開口部９１が広く開口している。この状態で上述の方法で防虫網７を取り付ける。その後、回動羽根４を室内側開口部９１から挿入し、回動軸体４２の円弧部４１１を第１支持部５１に当接させて位置決めし、室内端４４が上方に位置するように回動羽根４を回転させる。 Next, a method of attaching the rotary blade 4 to the frame body 2 will be described. The rotary blade 4 can be attached / detached from the indoor side. As shown in FIG. 10, the first holding body 5 is fixed to each of the facing surfaces 213 of the pair of vertical frames 21 with screws, and the indoor side opening 91 is widely opened. In this state, the insect net 7 is attached by the method described above. After that, the rotary blade 4 is inserted from the indoor opening 91, the arc portion 411 of the rotary shaft 42 is brought into contact with the first support 51 for positioning, and the rotary blade 4 is rotated so that the indoor end 44 is located upward. The moving blade 4 is rotated.
　続いて、第２保持体６を室内側開口部９１に挿入し、下当接縁６３１を第１保持体５の切り欠き縁部５４に当接させながら室外Ｏ側に押し込むと、側板部４１と縦枠２１の対向面２１３との隙間に第２保持体６がガイドされながら挿入され、奥当接縁６３２が第１保持体５の切り欠き縁部５４に接触する所定位置に配置される。この状態で、回動羽根４の回動軸体４２が第１支持部５１および第２支持部６１により挟持される。 Subsequently, the second holding body 6 is inserted into the indoor opening 91, and the lower contact edge 631 is pushed toward the outdoor O side while being in contact with the notched edge 54 of the first holding body 5, and the side plate portion 41 The second holding body 6 is inserted while being guided into the gap between the vertical frame 21 and the facing surface 213, and the back contact edge 632 is arranged at a predetermined position in contact with the notched edge portion 54 of the first holding body 5. .. In this state, the rotating shaft body 42 of the rotating blade 4 is sandwiched by the first support portion 51 and the second support portion 61.
　回動羽根４は、回動時に室内側開口部９１を閉鎖する閉位置側、または室内側開口部９１を最大開放する開位置側に向かって回動するように重心が設定されている。この状態では、回動羽根４は荷重バランスが室外端４５側に偏っており、回動羽根４は最大限開口した開位置に保持される。続いて、側板部４１の内側から回動羽根４の貫通孔４３、第２支持部６１のネジ孔６２、および縦枠２１の回動軸係合用のネジ孔にネジを挿入し、第２保持体６を縦枠２１に係合させる。この方法により幅方向Ｗの両端部に第２保持体６を取り付け、回動羽根４の枠体２への取り付けが完了する。 The center of gravity of the rotary blade 4 is set so as to rotate toward the closed position side that closes the indoor opening 91 at the time of rotation, or the open position side that opens the indoor opening 91 to the maximum. In this state, the load balance of the rotary blade 4 is biased toward the outdoor end 45 side, and the rotary blade 4 is held at the maximum open position. Subsequently, screws are inserted from the inside of the side plate portion 41 into the through hole 43 of the rotating blade 4, the screw hole 62 of the second support portion 61, and the screw hole for engaging the rotating shaft of the vertical frame 21, and the second holding is performed. The body 6 is engaged with the vertical frame 21. By this method, the second holding body 6 is attached to both ends in the width direction W, and the attachment of the rotating blade 4 to the frame body 2 is completed.
　回動軸体４２は支持体５１，６２内で円弧部４２３が支持体の円弧部４１１，５１０に摺接している。また、貫通孔４３はネジよりも大径に開口しているため、第２保持体６の枠体２に対する着脱時のみネジが通過し、第２保持体６が枠体２に係合された後は、貫通孔４２とネジとは干渉しない。そのため回動羽根４は回動自在な状態が保持される。この結果、回動羽根４は、幅方向の両端部が第１保持体５と第２保持体６との間に保持された状態で回動軸を中心に回動可能に羽根保持部３に係合される。 In the rotating shaft body 42, the arc portion 423 is in sliding contact with the arc portions 411 and 510 of the support in the supports 51 and 62. Further, since the through hole 43 has a larger diameter than the screw, the screw passes only when the second holding body 6 is attached to and detached from the frame body 2, and the second holding body 6 is engaged with the frame body 2. After that, the through hole 42 and the screw do not interfere with each other. Therefore, the rotary blade 4 is maintained in a rotatable state. As a result, the rotary blade 4 is rotatably formed on the blade holding portion 3 about the rotation shaft while both ends in the width direction are held between the first holding body 5 and the second holding body 6. Engage.
　図５及び図６に示すように、室外端４５が室内端４４よりも低い位置で保持された回動羽根４の開位置では、室外側開口部９２から室内側開口部９１まで換気経路Ｃが開放されて室内外の換気が行われる。換気経路Ｃの解放時は、防虫網７により虫や塵などの室内Ｉ側への侵入を防止できる。 As shown in FIGS. 5 and 6, at the open position of the rotary blade 4 in which the outdoor end 45 is held at a position lower than the indoor end 44, the ventilation path C extends from the outdoor opening 92 to the indoor opening 91. It is opened and ventilation is performed indoors and outdoors. When the ventilation path C is released, the insect net 7 can prevent insects and dust from entering the room I side.
　回動羽根４が開位置にあるとき、回動軸体４２の第１直線縁４２１が支持部５１，６１の第２ストッパ５１２に当接し、回動羽根４が過剰に回転することを防止している。 When the rotary blade 4 is in the open position, the first straight edge 421 of the rotary shaft body 42 comes into contact with the second stopper 512 of the support portions 51 and 61 to prevent the rotary blade 4 from rotating excessively. ing.
　さらに、回動羽根４が開位置にあるとき、回動羽根４の室外端４５側の外面にブラシ８０が接触または隙間を小さくしている。同様に、パッキン８１の突出片８１１が回動羽根４の外周面の近傍に位置する。このため、室外端４５と室外側壁部２３１との隙間に、防虫網７を通過した塵埃が侵入することを防止または軽減できる。また、僅かな隙間を風が通る際に生じる音の発生を防止または軽減できる。ブラシ部８は、回動羽根４と上枠２３との間の隙間に生じる空気の対流を防ぐ目的において、枠体２と回動羽根４との間の隙間に配置されていればよく、枠体２側または回動羽根４のいずれか一方に固定されていればよい。枠体２側にブラシ部８を設け、ブラシ８０が回動羽根４の外面に接触する構成とすると、回動羽根４に対する汚れの付着を防止する効果も得られる。 Further, when the rotary blade 4 is in the open position, the brush 80 contacts or reduces the gap on the outer surface of the rotary blade 4 on the outdoor end 45 side. Similarly, the protruding piece 811 of the packing 81 is located near the outer peripheral surface of the rotary vane 4. Therefore, it is possible to prevent or reduce the invasion of dust that has passed through the insect net 7 into the gap between the outdoor end 45 and the outdoor wall portion 231. In addition, it is possible to prevent or reduce the generation of sound generated when the wind passes through a slight gap. The brush portion 8 may be arranged in the gap between the frame body 2 and the rotary blade 4 for the purpose of preventing the convection of air generated in the gap between the rotary blade 4 and the upper frame 23, and the frame It may be fixed to either the body 2 side or the rotating blade 4. When the brush portion 8 is provided on the frame body 2 side and the brush 80 is in contact with the outer surface of the rotating blade 4, the effect of preventing dirt from adhering to the rotating blade 4 can also be obtained.
　換気経路Ｃを閉じたい場合、図７に示すように、回動羽根４を開位置から閉位置に回動させる。使用者が室内端４４を把持しながら下方に動かすと、回動羽根４の重心が室内端４４側に移動し、回動羽根４の荷重バランスが室内端４４側に偏り、室内端４４が防虫網７の把持部７３３とシール材８３との間の隙間に進入する。回動軸体４２の第２直線縁４２２が第１ストッパ５１１に当接し、回動羽根４のさらなる回動が規制される。回動羽根４は荷重バランスにより室内側開口部９１を閉じた閉位置に保持される。回動羽根４が閉位置に到達する際、室内端４４がシール材８３に接触する。この結果、室内端４４が下枠２２または網枠７１に接触して接触音が発生することや部品に傷が付くことを防止できる。また、室内端４４とシール材８３とが接触するため、換気経路Ｃを封止できる。回動羽根４が閉位置にあるとき、室内端４４は内横枠７３の把持部７３３と下枠２２のシール材８３との隙間に進入して保持される。この結果、回動羽根４と枠体２との間に空気が侵入する隙間が生じ難く、隙間風の発生を防止できる。 When it is desired to close the ventilation path C, the rotary blade 4 is rotated from the open position to the closed position as shown in FIG. When the user moves downward while grasping the indoor end 44, the center of gravity of the rotating blade 4 moves toward the indoor end 44, the load balance of the rotating blade 4 is biased toward the indoor end 44, and the indoor end 44 is insect repellent. It enters the gap between the grip portion 733 of the net 7 and the sealing material 83. The second straight edge 422 of the rotating shaft body 42 comes into contact with the first stopper 511, and further rotation of the rotating blade 4 is restricted. The rotary blade 4 is held in a closed position where the indoor opening 91 is closed due to the load balance. When the rotary blade 4 reaches the closed position, the indoor end 44 comes into contact with the sealing material 83. As a result, it is possible to prevent the indoor end 44 from coming into contact with the lower frame 22 or the net frame 71 to generate a contact sound or damage the parts. Further, since the indoor end 44 and the sealing material 83 come into contact with each other, the ventilation path C can be sealed. When the rotary blade 4 is in the closed position, the indoor end 44 enters and is held in the gap between the grip portion 733 of the inner horizontal frame 73 and the sealing material 83 of the lower frame 22. As a result, it is difficult for a gap for air to enter between the rotating blade 4 and the frame body 2, and the generation of draft can be prevented.
　回動羽根４が閉位置の状態では、回動羽根４で室内側開口部９１が閉じられた状態となる。このとき、室内Ｉ側では、回動羽根４の平坦部４７が室内側開口部９１に露出する。室内側開口部９１を覆う平坦部４７により、閉位置の回動羽根４がフラットな外観となり、回動羽根４と室内側開口部９１との一体感が得られ、外観意匠性に優れる。 When the rotary vane 4 is in the closed position, the indoor opening 91 is closed by the rotary vane 4. At this time, on the indoor side I side, the flat portion 47 of the rotating blade 4 is exposed to the indoor side opening 91. The flat portion 47 covering the indoor side opening 91 gives the rotating blade 4 in the closed position a flat appearance, provides a sense of unity between the rotating blade 4 and the indoor side opening 91, and is excellent in appearance design.
　回動羽根４を閉位置から開位置に回動させる場合、使用者が室内端４４を把持しながら上方に移動させると、回動羽根４の重心が室外端４５側に移動し、回動羽根４の荷重バランスが室外端４５側に偏り、回動羽根４が開位置に達し、かつ開位置に保持される。 When rotating the rotary blade 4 from the closed position to the open position, when the user moves the rotary blade 4 upward while grasping the indoor end 44, the center of gravity of the rotary blade 4 moves to the outdoor end 45 side, and the rotary blade 4 is rotated. The load balance of 4 is biased toward the outdoor end 45 side, and the rotary vane 4 reaches the open position and is held in the open position.
　次に、回動羽根４を取り外す場合、回動羽根４を開位置に移動させた後、第２保持体６を係合している係合ネジを外し、第２保持体６を室内Ｉ側に取り出す。続いて、回動羽根４を取り出す。回動羽根４を取り出す際、回動羽根４の中間固定部４１２付近は、上枠２３の上固定部２３０の湾曲面に近接しているため、回動軸体４２を室内Ｉ側に斜め下方に引きながら取り出す。この後、上述の方法で防虫網７を枠体２から取り外すことができる。 Next, when removing the rotating blade 4, after moving the rotating blade 4 to the open position, the engaging screw engaging the second holding body 6 is removed, and the second holding body 6 is moved to the indoor I side. Take out to. Subsequently, the rotary blade 4 is taken out. When the rotary blade 4 is taken out, the vicinity of the intermediate fixing portion 412 of the rotary blade 4 is close to the curved surface of the upper fixing portion 230 of the upper frame 23, so that the rotary shaft body 42 is obliquely downward toward the room I side. Take it out while pulling it. After that, the insect screen 7 can be removed from the frame 2 by the method described above.
　以上の構成により、本実施形態に係る換気装置１は、回動羽根４が枠体２に対して着脱可能に設けられているため、回動羽根４を枠体２から取り外してメンテナンス作業が行える。したがって、メンテナンス作業が容易に行える換気装置を提供できる。また、窓用の建具１０１の上方または下方に換気装置１を取り付けたサッシユニット１００によれば、窓を開放しなくても換気を行える。 With the above configuration, in the ventilation device 1 according to the present embodiment, since the rotating blades 4 are detachably provided with respect to the frame body 2, the rotating blades 4 can be removed from the frame body 2 for maintenance work. ..

Engage movably. As a result, the rotating blade 4 can be attached to and detached from the frame body 2 by the operation of attaching and detaching the second holding body 6 to and from the frame body 2 from the room I side, and maintenance work can be easily performed.
　本実施形態に係る換気装置１は、室外側開口部９２と回動羽根４との間に防虫網７が設けられているため、回動羽根４を開位置にして室内外を換気する際、防虫網７により埃や虫等の侵入を防ぐことができる。防虫網７が枠体２に対して室内Ｉ側より着脱可能に係合されているため、防虫網７の清掃等のメンテナンス作業が容易に行える。 In the ventilation device 1 according to the present embodiment, since the insect net 7 is provided between the outdoor opening 92 and the rotating blade 4, when the rotating blade 4 is opened to ventilate the inside and outside of the room, The insect net 7 can prevent the invasion of dust and insects. Since the insect repellent net 7 is detachably engaged with the frame body 2 from the indoor I side, maintenance work such as cleaning of the insect repellent net 7 can be easily performed.
　本実施形態に係る換気装置１は、室内側開口部９１の開口面積が所定面積となる位置で回動羽根４の回動が停止できる。したがって、換気量を段階的にコントロール可能であり、使用者の利便性に貢献できる。 In the ventilation device 1 according to the present embodiment, the rotation of the rotating blade 4 can be stopped at a position where the opening area of the indoor side opening 91 becomes a predetermined area. Therefore, the ventilation volume can be controlled step by step, which can contribute to the convenience of the user.
　本実施形態に係る換気装置１は、回動羽根４に対して室内側開口部９１と室外側開口部９２との間の通気経路を開放する方向または閉鎖する方向に力が加わると、回動羽根４自体の荷重バランスにより、回動羽根４が閉位置または開位置に向かって回動するように構成されている。さらに、羽根保持部３にはストッパ５１１，５１２が形成されているため、回動羽根４の回動を閉位置または開位置で停止できる。したがって、使用者は僅かな力を加えるだけで回動羽根４を開位置または閉位置に停止でき、回動羽根４の開閉操作を簡単に行える。 The ventilation device 1 according to the present embodiment rotates when a force is applied to the rotary blade 4 in the direction of opening or closing the ventilation path between the indoor side opening 91 and the outdoor side opening 92. The rotating blade 4 is configured to rotate toward a closed position or an open position depending on the load balance of the blade 4 itself. Further, since the blade holding portions 3 are formed with stoppers 511 and 512, the rotation of the rotating blade 4 can be stopped at the closed position or the open position. Therefore, the user can stop the rotary vane 4 at the open position or the closed position by applying a slight force, and the rotary vane 4 can be easily opened and closed.
　本実施形態に係る換気装置１は、水切りリブ２３２が室外側開口部９２の上端部から下垂するため、室外Ｏ側に向かって突出する従来の水切り部に比べて、水切り機能と外観意匠性とが両立できる。また、水切りリブ２３２が室外Ｏ側に突出しないため、室外Ｏ側の動線を妨げない。 In the ventilation device 1 according to the present embodiment, since the draining rib 232 hangs down from the upper end of the outdoor opening 92, the draining function and the appearance design are improved as compared with the conventional draining portion protruding toward the outdoor O side.
