Description

【0001】
【発明の属する技術分野】
本発明は、主として植物を育成する温室の換気装置に関し、特に温室の屋根面に設けられる換気装置の改良に関する。
【0002】
【従来の技術】
一般に植物を育成する温室は、たとえば、地上に多数のアーチ状パイプを起立し、このアーチ状パイプに直交する横方向支柱と、シート定着用のフレームを配設して骨組を構成し、透明または半透明な合成樹脂シートを上記シート定着用のフレームを介して固定しながら屋根面、側面および妻面に展張して形成されている。
【0003】
さらに、上記温室では換気を必要とするので、屋根面の任意の位置に開口部を形成し、この開口部に対向する天窓を備えた換気装置を設け、この天窓を開閉して換気を行っている。
【0004】
そして、従来の換気装置は、たとえば、温室の頂部たる棟部に設けた開口部と、この棟部に設けられた開口部を開閉する山型の天窓と、リンクを介して天窓を駆動する駆動ロッドとで構成され、駆動ロッドを軸方向に移動することにより、天窓を開口部から上方に移動させることができるものであって、この天窓の移動により、開口部が開放されて温室を換気することができる(たとえば、特許文献1参照)。
【0005】
また、この他に、屋根面に設けられた開口部を屋根面に沿ってスライドする天窓により開閉するとするもの(たとえば、特許文献2,3参照)や屋根面の大部分がリンク機構により回転および折畳まれることにより、屋根面が開口するもの(たとえば、特許文献4参照)もある。

【発明が解決しようとする課題】
しかしながら、上記した従来の換気装置では、機能上特に問題があるわけではないが、次のような不具合がある。
【0011】
すなわち、従来の換気装置は、温室の屋根面の全体にわたり設けられる大掛かりなものであり、装置そのものも高価であるので、温室にかかるコストが高くなってしまう。
【0012】
また、その設置には温室を構築する専門業者に頼らざるを得ず、農作業者が換気装置を追加しようと思っても、簡易に設置することができない。
【0013】
そこで、本発明は上記不具合を解消するために創案されたものであって、その目的とするところは、農作業者が簡易に温室の屋根面に設置可能であって、低コストな温室の換気装置を提供することである。
【0014】
【課題を解決するための手段】
本発明の第1の課題解決手段おける温室の換気装置は、屋根面に設けられる温室の換気装置において、当該換気装置が、窓枠と、窓枠の側部の内周側に張り出して設けた樋と、窓枠の内周側に上部側が窓枠に対し回動自在に取付けられた回動枠とを備え、上記回動枠は上記樋と窓枠の下部とをラップすることを特徴とする。
【0015】
第1の課題解決手段によれば、窓枠に回動枠を取付けた構成にしたことで軽量、コンパクト化されており、従来の換気装置に比較して安価であり、温室にかかるコストも従来に比較して減少させることができる。
【0016】
さらに、換気装置が軽量、コンパクトであることに加えて、ブラケットを介して簡易にパイプに定着できるので、施工業者に頼ることなく農作業者自身が簡易に換気装置を設置することができる。
【0017】
そして、窓枠に対して回動枠を回動させて窓枠を開放することにより温室を換気できるが、窓枠を遮断して状態で、たとえば、雨が降っても、回動枠は、窓枠の内周側に張り出した樋と窓枠の下部とをラップしており、回動枠の左右側部と窓枠の左右側部との間に侵入した雨水は樋を通過し温室外へ排水されるので、温室内に雨水が浸入することが防止されている。
【0018】
本発明の第2の課題解決手段おける温室の換気装置は、第1の課題解決手段において、回動枠の下部にカバー体を設け、このカバー体が窓枠の下部をラップすることを特徴とする。
【0019】
第2の課題解決手段によれば、回動枠の下部にはカバー体が設けられており、このカバー体が窓枠の下部をラップするので、回動枠上を流れ落ちる雨水は、このカバー体上を通過して回動枠と窓枠との間の隙間に侵入することが防止されており、この部位から温室内に雨水が浸入することは無い。
【0020】
本発明の第3の課題解決手段おける温室の換気装置は、第1または第2の課題解決手段において、回動枠の左右側部にカバー体を設け、このカバー体が窓枠の左右側部をラップすることを特徴とする。
【0021】
第3の課題解決手段によれば、回動枠の左右側部には、それぞれ、カバー体が装着され、この各カバー体はそれぞれ窓枠の左右側部をラップするので、回動枠の左右側部と窓枠の左右側部との間の隙間から雨水が侵入することを効果的に防止でき、雨水浸入抑制効果がより一層高くなる。
【0022】
本発明の第4の課題解決手段おける温室の換気装置は、第1から第3のいずれかの課題解決手段において、窓枠の左右側部がそれぞれ温室のシートが挿入される開口部巾狭の蟻溝フレームと、当該蟻溝フレーム内に上記シートを定着する係止部材と、蟻溝フレームの斜め下方に連設した樋とを備えてなり、窓枠の上下部がそれぞれ温室のシートを定着する開口部巾狭の蟻溝フレームと、当該蟻溝フレーム内に上記シートを定着する係止部材とを備えてなることを特徴とする。
【0023】
本発明の第5の課題解決手段おける温室の換気装置は、第1から第4のいずれかの課題解決手段において、回動枠の左右および下部がそれぞれ温室のシートが挿入される開口部巾狭の蟻溝フレームと、当該蟻溝フレーム内に上記シートを定着する係止部材とを備えてなることを特徴とする請求項1から4に記載の温室の換気装置。
【0024】
第4および第5の課題解決手段によれば、温室の骨組にあらかじめ換気装置を定着させておけば、温室全体にそのままシートを展張することができ、別個に換気装置にシートを展張する作業を省くことができるから、従来の換気装置に比較してその展張作業および換気装置取付作業が容易となる。
【0025】
本発明の第6の課題解決手段おける温室の換気装置は、第4または第5の課題解決手段において、窓枠の下部の蟻溝フレームに、当該蟻溝フレームの開口部を覆うカバー体を設けたことを特徴とする。
【0026】
第6の課題解決手段によれば、窓枠の下部の蟻溝フレームにもその上端開口部に着脱自在に装着されるカバー体が装着されているので、当該蟻溝フレーム内に雨水が溜まることが防止され、雨水が蟻溝フレームから溢れ出して、回動枠と窓枠との間の隙間に侵入することが防止されるから、雨水浸入抑制効果がより一層高くなる。
【0027】
本発明の第7の課題解決手段おける温室の換気装置は、第1から第6のいずれかの課題解決手段において、窓枠の背面側に防虫用の網を取付けたことを特徴とする。
【0028】
第7の課題解決手段によれば、窓枠1開放時に害虫などが温室内に侵入することを防止できる。
【0029】
【発明の実施の形態】
本発明の一実施の形態を、図1から図10に基づいて説明する。図1は、本発明の一実施の形態における温室の換気装置の正面側斜視図である。図2は、本発明の一実施の形態における温室の換気装置の背面側斜視図である。図3は、本発明の一実施の形態における温室の換気装置の分解斜視図である。図4は、窓枠の上部の拡大横断面図である。図5は、窓枠の下部の拡大横断面図である。図6は、窓枠の側部の下端部における拡大斜視図である。図7は、窓枠の側部の下端部における拡大横断面図である。図8は、窓枠をパイプ材に取付けるブラケットの斜視図である。図9は、窓枠をパイプ材に取付けるブラケットの側面図である。図10は、窓枠の下部の拡大横断面図である。
【0030】
一実施の形態における温室の換気装置は、図1から図3に示すように、窓枠1と、窓枠1の側部11,13の内周側に張り出して設けた樋21,22と、窓枠1の内周側に上部側が窓枠に対し回動自在に取付けられた回動枠3とで構成されている。
【0031】
以下、詳細に説明すると、窓枠1は、矩形であって、その上部10は、図4に示すように、温室のシートSを定着する開口部巾狭の蟻溝フレーム50と、当該蟻溝フレーム50の図4中左端に連接され回動枠3を係合する係合部52と、当該蟻溝フレーム50内に上記シートSを定着する係止部材たる係止線条51とで構成されている。なお、この係合部52は、横断面略C型に形成され、図4中上端は、カール部53が設けられ、このカール部53で後述する回動枠3の上部30に設けた腕72の先端を抱持することにより、この係合部52が腕72と係合し、窓枠1の上部10に回動枠3の上部30が回動自在に取付けられることとなる。また、係合部52の図4中上端は、カールさせてあるので、シートSに係合部52とが擦れあっても、シートSの表面を傷めることが無い。
【0032】
さらに、窓枠1の下部12は、図5に示すように、温室のシートSを定着する開口部巾狭の蟻溝フレーム55と、当該蟻溝フレーム55の図5中右端部から延設されるL字状の回動枠受部56と、当該蟻溝フレーム55内に上記シートSを定着する係止部材たる係止線条51とで構成され、その左側部11は、図3および図6に示すように、シートSが挿入される開口部巾狭の蟻溝フレーム60と、当該蟻溝フレーム60内に上記シートSを定着する係止部材たる係止線条51と、蟻溝フレーム60の右斜め下方に連設した蟻溝フレーム状の樋21とで構成され、その右側部13は、図3に示すように、左側部11と同様に、シートSが挿入される開口部巾狭の蟻溝フレーム65と、当該蟻溝フレーム65内に上記シートSを定着する係止部材たる係止線条51と、蟻溝フレーム65の斜め下方に連設した蟻溝フレーム状の樋22とで構成され、右側部13は、左側部11の蟻溝フレーム60と樋21をちょうど左右逆に配置としたものである。さらに左右側部11,13の下端には、図1に示すように、それぞれ、雨水を温室外に排水するためのホースHを接続するためのソケット40が接続されている。このソケット40は、図6および図7に示すように、外部に開口する外側通路42,43と中央通路44とを備えたソケット本体41と、ソケット本体41の上部に一体的に設けられて左右側部11,13の樋21,22の下部を抱持する抱持部45,46と、外側通路42とソケット本体の下部外方とを連通する接続部47とで構成され、この接続部47にはホースHが嵌合される。そして、樋21,22内に侵入した雨水は、樋21,22内から外側通路42,43もしくは中央通路44を通過して接続部47に導かれ、ホースHで温室外へ排水される。なお、ソケット本体41の図7中左右幅は、樋21,22に取付けられた状態で蟻溝フレーム60、65に対向する幅に設定されており、蟻溝フレーム60,65内に挿入されているシートSに経年劣化等により亀裂が生じて、蟻溝フレーム60,65内に雨水が浸入しても、ソケット本体41で雨水を回収できるので、温室内に雨水が浸入することを防止している。
【0033】
さらに、上記上下部10,12の蟻溝フレーム50,55の図3中左右端が、それぞれ左右側部11,13に、樋21,22の上面に重なるようにしてリベットで結合されている。なお、結合方法はリベット結合以外にボルトとナットや溶接等の他に公知の方法を用いるとしてもよい。したがって、窓枠1の内周側には、係合部52、樋21,22および回動枠受部56が張り出すように配置されることとなる。
【0034】
他方、回動枠3は、矩形に形成され、その上部30は、図4に示すように、温室のシートSを定着する開口部巾狭の蟻溝フレーム70と、当該蟻溝フレーム70の底部の図4中右側から延設される略C型の腕72と、当該蟻溝フレーム70の底部の図4中左側から延設される板状の水平部71とで構成され、その下部32は、図5に示すように、温室のシートSを定着する開口部巾狭の蟻溝フレーム75と、当該蟻溝フレーム75の図5中右端部から延設されるL字状の連結部76と、当該蟻溝フレーム75内に上記シートSを定着する係止部材たる係止線条51とで構成され、その左側部31は、図3に示すように、シートSが挿入される開口部巾狭の蟻溝フレーム80と、当該蟻溝フレーム80の底部の図3中右側から延設される板状の水平部81と、当該蟻溝フレーム80内に上記シートSを定着する係止部材たる係止線条51とで構成され、その右側部33は、図3に示すように、左側部31と同様に、シートSが挿入される開口部巾狭の蟻溝フレーム85と、当該蟻溝フレーム85の底部の図3中左側から延設される板状の水平部86と、当該蟻溝フレーム85内に上記シートSを定着する係止部材たる係止線条51とで構成され、右側部33は、左側部31の蟻溝フレーム80と水平部81をちょうど左右逆に配置としたものである。そして、左右側部31,33の水平部81,86および蟻溝フレーム80,85の図3中上下端が、それぞれ、上記上下部30,32の水平部71および連結部76の上面に重なるようにしてリベットで結合されている。なお、結合方法はリベット結合以外にボルトとナットや溶接等の他に公知の方法を用いるとしてもよい。
【0035】
また、回動枠3の上部30と下部32との間には、2本の補強材90,90が掛け渡されており、回動枠3を補強している。なお、この補強材90,90は、回動枠3が当該回動枠3の充分確保される材質で作られる場合には、設ける必要は無い。
【0036】
そして、このように構成された回動枠3は、図4に示すように、上部30の腕72の先端を窓枠1の上部10に設けた係合部52に引掛けることにより、窓枠1の内周側に上部30の腕72の先端を支点として回動自在に取付けられる。このとき、回動枠3の外形は、窓枠1の内周で作られる形状と略同じ寸法ととなるように設定されており、回動枠3が窓枠1の内周側に取付けられると、窓枠1の内周側に張り出している、係合部52、樋21,22および回動枠受部56をラップするようになっている。
【0037】
なお、窓枠1に回動枠3を取付けるには、上述のように、腕72の先端を係合部52内に引掛けることによる以外にも、回動枠30の左右側部31,33の図3中上端近傍を窓枠1の左右側部11,13に軸支させる等、他の方法により取付けても良いが、腕72の先端を係合部52内に引掛けることによる方が、軸等の取付部材を必要としないので、換気装置をコスト的に安く作ることができる。
【0038】
また、この窓枠1の上部10と下部12の略中央にはレール91が掛け渡されており、このレール91にスライド自在かつレール91上に固定することが可能なスライド93が設けられ、このスライド93と上記補強材90,90との間にスライド93および補強材90,90にそれぞれ回動自在に介装されるリンク94,94が設けられており、このスライド93がレール91上をスライドすることにより、回動枠3が窓枠1に対し回動することができるようになっており、これにより、窓枠1を開放状態と閉鎖状態とに切り替えることができる。ちなみに、具体的には、図示はしないが、レール91に複数の溝を設け、スライド93にはこの溝(図示せず)に出入可能な係止部材(図示せず)を設け、係止部材(図示せず)を溝(図示せず)に出入りさせることによって、スライド93をスライドおよびレール91上に多段階に固定可能な公知のスライドを使用すればよく、また、この窓枠1は、温室の屋根面に取付けられることから、スライド93を地上から操作できるように、たとえば、図2に示すように、係止部材(図示せず)に連結される紐R等で上記係止部材(図示せず)の出入りを操作できるようにしておくと良い。なお、回動枠3を回動させて窓枠1を開放状態と閉鎖状態とに切り替えることができればよいので、スライドを無段階に固定できるようにしてもよく、また、たとえば、スライドをモータ等の駆動源で駆動したり、シリンダで回動枠を開閉したり、さらに、他の慣用されている方法を用いて回動枠3を回動させても良いことは無論である。
【0039】
そして、この換気装置を温室に取付けるには、たとえば、図3に示すように、温室の屋根面の骨組を構成するパイプPに、4つのブラケット200を介して窓枠1を固定する。このブラケット200は、図8および図9に示すように、横断面コ字状のブラケット本体201と、窓枠1の上部10と下部12の蟻溝フレーム50,55を抱持する抱持部202と、楔203とで構成されている。そして、窓枠1の下部12については蟻溝フレーム55を抱持部202で抱持しながら、ブラケット本体201内にパイプPを挿入し、その状態を維持しながら楔203をブラケット本体201に設けた楔孔204に打ち込む。すると、蟻溝フレーム55およびパイプPは、抱持部202と楔203とで挟持されることになり、これにより、蟻溝フレーム55はパイプPに固定される。また、上部10についても同様である。したがって、上述のように、窓枠1をブラケット200を介してパイプPに固定できるので、換気装置全体がパイプPに固定される。
【0040】
つづいて、温室の骨組にシートSを展張するが、上述のように、すでに換気装置はパイプPに取付けられた状態下でシートSが展張されることとなる。そして、シートSの展張が終了した後に、窓枠1の上部10、下部12、左右側部11,13の各蟻溝フレーム50,55,60,65内にシートSを挿入し、その上から、係止線条51を自己の弾性に抗して強制的に嵌合する。すると、シートSは係止線条51の弾性力で各蟻溝フレーム50,55,60,65の内壁に押圧されるので、シートSは係止線条51と各蟻溝フレーム50,55,60,65との間に挟持されて窓枠1に定着される。さらに、回動枠3の下部32、左右側部31,33の各蟻溝フレーム75,80,85内にシートSを挿入し、その上から、係止線条51を自己の弾性に抗して強制的に嵌合する。すると、シートSは係止線条51の弾性力で各蟻溝フレーム75,80,85の内壁に押圧されるので、シートSは係止線条51と各蟻溝フレーム75,80,85との間に挟持されて回動枠3に定着される。そうしておいてから、窓枠1と回動枠3との間のうち窓枠1の上部10と回動枠3の上部30との間を残してシートSをカッター当で切断すると、回動枠3は窓枠1に対して回動することができるようになり、この回動枠3の回動により、窓枠1を開放および遮断することができ、温室の換気を行えるようになる。したがって、従来の換気装置では、温室の骨組にシートSを展張する際、どうしても温室自体とは別個に換気装置自体にシートSを展張する必要があるが、本発明の換気装置にあっては、温室の骨組にあらかじめ換気装置を定着させておけば、温室全体にそのままシートSを展張することができ、別個に換気装置にシートSを展張する作業を省くことができるから、従来の換気装置に比較してその展張作業および換気装置取付作業が容易となり、また、本発明の換気装置は、窓枠に回動枠を取付けた構成にしたことで軽量、コンパクト化されており、従来の換気装置に比較して安価であり、温室にかかるコストも従来に比較して減少させることができる。
【0041】
さらに、換気装置が軽量、コンパクトであることに加えて、ブラケット200を介して簡易にパイプPに定着できるので、施工業者に頼ることなく農作業者自身が簡易に換気装置を設置することができる。
【0042】
さらに、図3に示すように、回動枠3の下部32、左右側部31,33の各蟻溝フレーム75,80,85には、それぞれ、カバー体79,110,120が装着される。このカバー体79は、図5に示すように、蟻溝フレーム75の上端開口部に着脱自在に装着されるカバー体本体77と、カバー体本体77の図5中左端から水平に延設される板上のラップ部78とで構成され、他のカバー体110,120も同様に、それぞれ、カバー体本体112,122とラップ部111,121とで構成されている。また、窓枠1の下部12の蟻溝フレーム55にもその上端開口部に着脱自在に装着されるカバー体130が装着される。
【0043】
このように、構成された換気装置では、窓枠1に対して回動枠3を回動させて窓枠1を開放することにより温室を換気できるが、窓枠1を遮断して状態で、たとえば、雨が降っても、回動枠3は、窓枠1の内周側に張り出した樋21,22と窓枠1の下部12とをラップしており、回動枠3の左右側部31,33と窓枠1の左右側部11,13との間に侵入した雨水は樋21,22を通過しソケット40,40を介してホースHで温室外へ排水されるので、温室内に雨水が浸入することは無い。
【0044】
また、回動枠3の下部32の蟻溝フレーム75の開口部にはカバー体79が設けられており、このカバー体79が窓枠1の下部12をラップするので、回動枠3上を流れ落ちる雨水は、このカバー体79上を通過して回動枠3と窓枠1との間の隙間に侵入することが防止されており、この部位から温室内に雨水が浸入することは無い。
【0045】
さらに、回動枠3の左右側部31,33の各蟻溝フレーム80,85には、それぞれ、カバー体110,120が装着され、このカバー体110,120は、窓枠1の左右側部11,13をラップするので、各蟻溝フレーム80,85内に雨水が侵入することを防止できるとともに、回動枠3の左右側部31,33と窓枠1の左右側部11,13との間の隙間から雨水が侵入することを効果的に防止でき、また、さらに、窓枠1の下部12の蟻溝フレーム55にもその上端開口部に着脱自在にカバー体130が装着されているので、当該蟻溝フレーム55内に雨水が溜まることが防止され、雨水が蟻溝フレーム55から溢れ出して、回動枠3と窓枠1との間の隙間に侵入することが防止されるから、雨水浸入抑制効果がより一層高くなる。なお、回動枠3の下部32の蟻溝フレーム75に装着されるカバー体79のラップ部78の図9中左右幅を長く設定して、窓枠1の下部12の全体を覆うようにすれば、窓枠1の下部12の蟻溝フレーム55にカバー体130を装着しなくとも同様の効果を得ることが可能である。
【0046】
したがって、窓枠1および回動枠3にカバー体を装着することにより雨水浸入抑制効果がより一層高くなるのである。
【0047】
なお、回動枠3の下部32、左右側部31,33の蟻溝フレーム75,80,85に、それぞれ、カバー体79,110,120のラップ部78,111,121に相当する部材を一体的に設けるとしてもよい。

Incidentally, although not specifically shown, the rail 91 is provided with a plurality of grooves, and the slide 93 is provided with a locking member (not shown) that can be put in and out of the groove (not shown). A known slide that can fix the slide 93 on the slide and the rail 91 in multiple stages by moving a notch (not shown) into and out of a groove (not shown) may be used. Since it is attached to the roof surface of the greenhouse, the locking member (for example, as shown in FIG. 2) with a string R connected to a locking member (not shown) so that the slide 93 can be operated from the ground. It is good to be able to operate the entry / exit (not shown). Note that it is sufficient that the window frame 1 can be switched between the open state and the closed state by rotating the rotation frame 3, so that the slide can be fixed steplessly. It goes without saying that the rotary frame 3 may be rotated by using another driving method, by opening and closing the rotary frame with a cylinder, or by using other commonly used methods.
[0039]
And in order to attach this ventilation apparatus to a greenhouse, as shown in FIG. 3, the window frame 1 is fixed to the pipe P which comprises the framework of the roof surface of a greenhouse via the four brackets 200, for example. As shown in FIGS. 8 and 9, the bracket 200 includes a bracket body 201 having a U-shaped cross section and a holding portion 202 that holds the dovetail frames 50 and 55 in the upper portion 10 and the lower portion 12 of the window frame 1. And a wedge 203. And about the lower part 12 of the window frame 1, the pipe P is inserted in the bracket main body 201, holding the dovetail frame 55 with the holding part 202, and the wedge 203 is provided in the bracket main body 201, maintaining the state. The wedge hole 204 is driven. Then, the dovetail frame 55 and the pipe P are sandwiched between the holding portion 202 and the wedge 203, whereby the dovetail frame 55 is fixed to the pipe P. The same applies to the upper part 10. Therefore, since the window frame 1 can be fixed to the pipe P via the bracket 200 as described above, the entire ventilation device is fixed to the pipe P.
[0040]
Subsequently, the sheet S is expanded on the framework of the greenhouse. As described above, the sheet S is already expanded under the condition that the ventilation device is already attached to the pipe P. Then, after the expansion of the sheet S is completed, the sheet S is inserted into the dovetail frames 50, 55, 60, 65 of the upper part 10, the lower part 12, and the left and right side parts 11, 13 of the window frame 1, and from above The engaging wire 51 is forcibly fitted against its own elasticity. Then, the sheet S is pressed against the inner wall of each dovetail frame 50, 55, 60, 65 by the elastic force of the engagement line 51, so that the sheet S is engaged with the engagement line 51 and each dovetail frame 50, 55, 60 and 65 and fixed to the window frame 1. Further, the sheet S is inserted into the dovetail frames 75, 80, 85 of the lower portion 32 of the rotating frame 3 and the left and right side portions 31, 33, and from above, the locking filament 51 is resisted against its own elasticity. Forcibly mating. Then, the sheet S is pressed against the inner wall of each dovetail frame 75, 80, 85 by the elastic force of the locking line 51, so that the sheet S has the locking line 51 and each dovetail frame 75, 80, 85 And is fixed to the rotating frame 3. After that, when the sheet S is cut with a cutter while leaving the space between the upper part 10 of the window frame 1 and the upper part 30 of the rotation frame 3 between the window frame 1 and the rotation frame 3, The moving frame 3 can be rotated with respect to the window frame 1, and the rotation of the rotating frame 3 can open and close the window frame 1 and can ventilate the greenhouse. . Therefore, in the conventional ventilator, when the sheet S is expanded on the framework of the greenhouse, it is necessary to extend the sheet S on the ventilator itself separately from the greenhouse itself. However, in the ventilator of the present invention, If the ventilator is fixed in advance in the framework of the greenhouse, the sheet S can be expanded as it is in the entire greenhouse, and the work of separately extending the sheet S to the ventilator can be omitted. In comparison, the expansion work and the ventilator mounting work are facilitated, and the ventilator of the present invention is light and compact because of the structure in which the rotating frame is attached to the window frame. Compared to the conventional method, the cost of the greenhouse can be reduced.
[0041]
Furthermore, since the ventilator is light and compact, it can be easily fixed to the pipe P via the bracket 200, so that the farmer can easily install the ventilator without relying on the contractor.
[0042]
Further, as shown in FIG. 3, cover bodies 79, 110, and 120 are attached to the dovetail frames 75, 80, and 85 of the lower portion 32 and the left and right side portions 31 and 33 of the rotating frame 3, respectively. As shown in FIG. 5, the cover body 79 extends horizontally from the cover body main body 77 detachably attached to the upper end opening of the dovetail frame 75 and the left end of the cover body main body 77 in FIG. 5. The other cover bodies 110 and 120 are similarly composed of cover body bodies 112 and 122 and wrap parts 111 and 121, respectively. Further, the dovetail frame 55 at the lower portion 12 of the window frame 1 is also attached with a cover body 130 that is detachably attached to the upper end opening.
[0043]
Thus, in the configured ventilation device, the greenhouse can be ventilated by rotating the rotating frame 3 with respect to the window frame 1 and opening the window frame 1, but with the window frame 1 blocked, For example, even if it rains, the rotating frame 3 wraps the eaves 21 and 22 projecting to the inner peripheral side of the window frame 1 and the lower portion 12 of the window frame 1, and the left and right side portions of the rotating frame 3. Rainwater that has entered between the left and right side portions 11 and 13 of the window frame 1 passes through the troughs 21 and 22 and is drained outside the greenhouse by the hose H through the sockets 40 and 40. Rainwater never enters.
[0044]
Further, a cover body 79 is provided at the opening of the dovetail frame 75 at the lower portion 32 of the rotating frame 3, and the cover body 79 wraps the lower portion 12 of the window frame 1. The rainwater that flows down is prevented from passing over the cover body 79 and entering the gap between the rotating frame 3 and the window frame 1, and rainwater does not enter the greenhouse from this site.
[0045]
Further, cover bodies 110 and 120 are respectively attached to the dovetail frames 80 and 85 of the left and right side portions 31 and 33 of the rotating frame 3, and the cover bodies 110 and 120 are respectively connected to the left and right side portions of the window frame 1. 11 and 13 wraps to prevent rainwater from entering the dovetail frames 80 and 85, and the left and right side portions 31 and 33 of the rotating frame 3 and the left and right side portions 11 and 13 of the window frame 1. It is possible to effectively prevent rainwater from invading through the gaps between them, and the dovetail frame 55 at the lower part 12 of the window frame 1 is also detachably attached to the upper end opening thereof. Therefore, it is prevented that rainwater accumulates in the dovetail frame 55, and rainwater is prevented from overflowing from the dovetail frame 55 and entering the gap between the rotating frame 3 and the window frame 1. In addition, the rainwater infiltration suppression effect is further enhanced. Note that the width of the lap portion 78 of the cover body 79 attached to the dovetail frame 75 of the lower portion 32 of the rotating frame 3 is set to be long in FIG. 9 so as to cover the entire lower portion 12 of the window frame 1. For example, the same effect can be obtained without attaching the cover body 130 to the dovetail frame 55 in the lower portion 12 of the window frame 1.
[0046]
Therefore, the rainwater permeation suppression effect is further enhanced by attaching the cover body to the window frame 1 and the rotation frame 3.
[0047]
Members corresponding to the wrap portions 78, 111, and 121 of the cover bodies 79, 110, and 120 are integrated with the dovetail frames 75, 80, and 85 of the lower portion 32 of the rotating frame 3 and the left and right side portions 31 and 33, respectively. It may also be provided.

The end of the insect repellent net N is sandwiched and attached. Further, a pulley K is attached to the upper part 10 or the lower part 12 of the window frame 1 so that the string R or the like that drives the slide that will be attached to the slide 93 does not interfere with the insect-proof net N. When the slide 93 is driven by pulling, the cord R is prevented from interfering with the insect net N and the insect net N is prevented from falling off the window frame 1. The insect repellent net N attached in this way prevents insects and the like from entering the greenhouse when the window frame 1 is opened.

【The invention's effect】
According to the invention of each claim, it is lightweight and compact by having a structure in which a rotation frame is attached to a window frame, and is less expensive than a conventional ventilator, and the cost of a greenhouse is also conventional. It can be reduced in comparison.
[0050]
Furthermore, since the ventilator is lightweight and compact, it can be easily fixed to the pipe via the bracket, so that the farmer can easily install the ventilator without relying on the contractor.
[0051]
And the greenhouse can be ventilated by rotating the rotating frame with respect to the window frame and opening the window frame, but in the state where the window frame is shut off, for example, even if it rains, the rotating frame The ridge overhanging the inner periphery of the window frame and the lower part of the window frame are wrapped, and rainwater that enters between the left and right sides of the rotating frame and the left and right sides of the window frame passes through the fence and goes outside the greenhouse As a result, it is prevented that rainwater enters the greenhouse.
[0052]
According to the second aspect of the present invention, the cover body is provided at the lower part of the rotating frame, and the cover body wraps the lower part of the window frame. It is prevented from passing through the gap between the rotating frame and the window frame, and rainwater does not enter the greenhouse from this site.
[0053]
According to the third aspect of the present invention, the cover body is attached to the left and right side portions of the rotating frame, and each cover body wraps the left and right side portions of the window frame. It is possible to effectively prevent rainwater from entering from the gap between the left and right side portions of the window frame and the rainwater permeation suppressing effect is further enhanced.
[0054]
According to the invention of claim 4 and claim 5, if the ventilation device is fixed in advance in the framework of the greenhouse, the sheet can be spread as it is in the whole greenhouse, and the work of separately spreading the sheet on the ventilation device is performed. Since it can be omitted, the extension work and the ventilation apparatus mounting work are facilitated as compared with the conventional ventilation apparatus.
[0055]
According to the sixth aspect of the present invention, since the cover body that is detachably attached to the upper end opening of the dovetail frame at the lower part of the window frame is attached, rainwater can accumulate in the dovetail frame. This prevents the rainwater from overflowing from the dovetail frame and entering the gap between the rotating frame and the window frame, so that the rainwater intrusion suppressing effect is further enhanced.
[0056]
According to the invention of claim 7, it is possible to prevent pests and the like from entering the greenhouse when the window frame 1 is opened.
