Description

【０００１】
【発明の属する技術分野】
本発明は、例えばマンションや戸建等の一般住宅家屋において、戸枠に網面を張着して成る網戸に対し、屋外から屋内を透視不可能な目隠し用板体を屋内側から取り付けられるようした目隠し装置に関するものである。
【０００２】
【従来の技術】
従来から、この種の網戸における目隠し装置としては、例えば実開昭５４−１１９２４９号公報に開示されているように、戸枠に網面を張着して成る網戸において戸枠の左右両縦框間に複数の帯状の不透視体を上下方向に積み重ねるように嵌挿して網面全体を覆うようにした構成のものがある。
【０００３】
また、実開昭５６−１４８５００号公報に開示されているように、外面に網体を張設した戸枠の内周縁部に断面略逆Ｆ字形の溝枠部を連設して当該溝枠部の内側にすだれ体の端部を介在させ、前記溝枠部に嵌着させるようにしてすだれ体の端部外面に受け縁付きすだれ縁押さえを被着させることで戸枠にすだれ体を保持させるようにした構成のものがある。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した従来例において例えば実開昭５４−１１９２４９号公報に開示さている目隠し付網戸では、複数の帯状の不透視体自体はメクラ板であるため換気性、通気性が全く無いのである。また複数の帯状の不透視体を単に上下方向に積み重ねるようにして左右両縦框間に嵌挿させているだけであり、また、網面側には不透視体を支持するものが何もないため、不透視体自体が網面に直接当ってしまいこれを変形させたり傷つけたりしてしまう。さらに不透視体自体にフード付開口部を備えた場合には、一般にフード部自体は開口部の上縁から横方向に突出させ且つ下方に向けて湾曲させた状態となって網面側に突出し全体的に奥行長さが大きくなっているので、不透視体と網戸との僅かなスペースでは不透視体のフード部が網面に直接当ってしまう等の問題点を有していた。
【０００５】
一方、実開昭５６−１４８５００号公報に開示されているすだれ付き網戸では、断面略逆Ｆ字形の溝枠部を戸枠の内周縁部に連設させたり、すだれ体の端部外面に受け縁付きすだれ縁押さえを被着させたりする等の構造が非常に複雑な構造となるから高価な網戸となってしまい、しかも一般に使用されている網戸に対してこのようなすだれ体を取り付けるための構造を設けることは不可能である等の網戸に対する汎用性に乏しい等の問題点を有していた。
【０００６】
そこで本発明は叙上のような従来存した諸事情に鑑み創出されたもので、戸枠に網面を張着して成る網戸において、フード付開口部を備えた不透視体自体の簡単な変形構成によりプライバシーを保護しながら換気性、通気性、採光性等を可能にさせ、また従来のようにすだれ体を取り付けるための溝枠部を連設したり、すだれ縁押さえを被着させたりする等の複雑な構造としなくても一般に使用されている網戸に対して戸枠の屋内側の左右両縦框間に容易に、しかも戸枠の縦横の大きさに対応調整して透視不可能な目隠し用板体を取り付けることができ、また従来の如く不透視体のフード部が網面に直接当ってしまうことがなくしっかりと戸枠に保持できるものとした目隠し装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上述した課題を達成するため、本発明にあっては、戸枠の屋内側の左右両縦框間に装着された屋外から透視不可能な目隠し用板体１に、板片に並列配置した複数段の折込部２１を交互に逆向きに折り込むことにより第１傾斜面部２２、第２傾斜面部２３それぞれを交互に連続して成る蛇腹状の折込板面部２と、折込板面部２の各第１傾斜面部２２もしくは各第２傾斜面部２３のいずれかに切り起こし状に突出して成るフード付開口部Ｐとを形成したものであり、目隠し用板材１自体は透視性が低い、いわゆる半透明な肉薄素材によって形成されている。
フード付開口部Ｐは、折込板面部２における折込部２１に形成された折曲縁から第１傾斜面部２２もしくは第２傾斜面部２３のいずれかの面内を折込板面部２自体に平行となるように切り起こすことによりフード部２５が形成されているものとできる。
折込板面部２の左右両縁端部には、戸枠の屋内側の左右両縦框に装着されるスライド着脱式の複数の保持枠部３を適当な間隔をおいて配装してあるものとできる。
保持枠部３は、戸枠の屋内側の縦框を咬持させるよう一側端に一体形成した略コ字枠状の縦框側保持アーム部３１と、折込部２１を介して山型状に形成された第１傾斜面部２２および第２傾斜面部２３に弾発的に圧接保持させるよう他側端の左右内壁面縦方向に沿って内側に向けて山型状に折曲した板発条から成る複数の取付係合部３３を備えて一体形成した略コ字枠状の折込板面部側保持アーム部３２とを有する全体略Ｈ型を呈する短尺帯枠形状に形成したものとできる。
２枚の折込板面部２を裏表且つ上下を逆向きにして配置させ、それぞれの第１傾斜面部２２同士および第２傾斜面部２３同士を合致させるようにして互いに横方向にスライド可能に接合配置させたものとできる。
折込板面部２同士の接合位置における前面側または後面側のフード部２５先端部から合致した第１傾斜面部２２同士もしくは第２傾斜面部２３同士にかけて嵌挿配置されて第１傾斜面部２２同士もしくは第２傾斜面部２３同士を圧接固定させる２枚折帯板状の保持部材６１を備えたものとできる。
複数の折込板面部２を開口部２４同士およびフード部２５同士の適数を合致させて上下方向に連結可能にして構成することができる。
折込板面部２同士の連結位置における合致した第１傾斜面部２２縁端部もしくはフード部２５先端部から嵌挿配置されて第１傾斜面部２２同士もしくはフード部２５同士を咬持させる２枚折帯板状の保持部材５１を備えたものとできる。
【０００８】
以上のように構成された本発明に係る目隠し装置において、蛇腹状の折込板面部２の各第１傾斜面部２２もしくは各第２傾斜面部２３のいずれかに形成されたフード付開口部Ｐは、屋内をフード部２５によって隠させながらも開口部２４を介しての屋内の換気や屋外との通気、あるいは屋外から屋内への採光等を容易に行わせる。
折込部２１の折曲縁から第１傾斜面部２２もしくは第２傾斜面部２３のいずれかの面内を切り起こして突出形成されたフード部２５は、網面側に突出せずに折込板面部２自体に平行であるため、不透視体のフード部２５の網面に対する当接突っ掛かりを防止させる。
全体略Ｈ型の短尺帯枠形状を呈して成る保持枠部３の略コ字枠状の折込板面部側保持アーム部３２は、自体を折込板面部２の左右両縁端部にスライド装着させ、折込板面部側保持アーム部３２の複数の取付係合部３３に第１傾斜面部２２および第２傾斜面部２３を弾発的に圧接保持させる。
一方、保持枠部３の略コ字枠状の縦框側保持アーム部３１は、自体を縦框に咬持させるようにして戸枠の屋内側の左右両縦框間に折込板面部２を装着させる。複数の折込板面部２を裏表且つ上下を逆向きにして配置させ、第１傾斜面部２２同士および第２傾斜面部２３同士を合致させた状態で互いに横方向にスライド可能に接合配置させて成る目隠し用板体１は、戸枠の左右幅寸法の大きさに対応調整可能にさせる。
２枚折帯板状の保持部材６１は、折込板面部２同士の接合位置における前面側または後面側のフード部２５先端部から合致した第１傾斜面部２２同士もしくは第２傾斜面部２３同士にかけて嵌挿配置されて第１傾斜面部２２同士もしくは第２傾斜面部２３同士を圧接固定させることにより、接合位置における折込板面部２同士の前後のバタつきを防止させる。
複数の折込板面部２を開口部２４同士およびフード部２５同士の適数を合致させて上下方向に連結して成る目隠し用板体１は、戸枠の上下幅寸法の大きさに対応調整可能にさせる。
２枚折帯板状の保持部材５１は、折込板面部２同士の連結位置における合致した第１傾斜面部２２縁端部もしくはフード部２５先端部に嵌挿配置されて第１傾斜面部２２同士もしくはフード部２５同士を咬持させることにより複数の折込板面部２同士をしっかりと保持固定させる。
【０００９】
【発明の実施の形態】
以下図面を参照して本発明の一実施の形態を説明すると、図において示される符号１は、例えばマンションや戸建等の一般住宅家屋において網戸とガラス戸との間に配される主としてプライバシー保護を目的とし、さらに通気性、換気性、採光性等を兼ね備えた目隠し用板体である。この目隠し用板体１は、図１に示すように、屋外からは透視不可能な不透明体または半透明体すなわち透視性が低い肉薄素材により形成され、互いに横方向にスライド可能に接合配置した左右の蛇腹状の折込板面部２と、折込板面部２の左右両縁端部の例えば３箇所に適当な間隔をおいてスライド装着させた全体略Ｈ型の短尺帯枠形状を呈し、例えば折込板面部２の左右側縁の上部、ほぼ中央部、下部それぞれに配装して成る合計６個の保持枠部３とを備えている。そして、戸枠に網面を張着して成る網戸における当該戸枠の内周縁部を形成する屋内側の左右両縦框間に保持枠部３を介して当該折込板面部２が装着されるものとしてある。
【００１０】
図２、図３に示すように、折込板面部２は、肉厚の薄い板片に並列配置した複数段の折込部２１を交互に逆向きに折り込むことにより横長矩形状の第１傾斜面部２２、横長矩形状の第２傾斜面部２３それぞれを交互に連続した全体面が蛇腹状またはジグザグ状に形成してある。このとき折込部２１を介しての第１傾斜面部２２と第２傾斜面部２３との間の挟角度βを鈍角例えば約１２０°に設定してある。そして、折込板面部２における折込部２１の中央横長部分を折曲縁とし、折曲縁を介して第１傾斜面部２２もしくは第２傾斜面部２３のいずれかの面内に横長Ｕ字状の切込部を形成して当該折曲縁から第１傾斜面部２２もしくは第２傾斜面部２３のいずれかの面内を折込板面部２自体に平行となるように例えばその起立する狭角度αを約３０°に設定して扉状に切り起こし開放させることでフード部２５を形成してある。
【００１１】
これにより折込板面部２の各第１傾斜面部２２もしくは各第２傾斜面部２３のいずれか一方に横長矩形状の開口部２４が形成されると共に、開口部２４と等しい面積を有する切片状のフード部２５を開口部２４上縁から鉛直下方へ向けて突出させた状態となった換気・通気用のフード付開口部Ｐが形成されるものとしてある。このとき開口部２４面とフード部２５との間の挟角度αは約３０°となるので、折込板面部２を正面から見れば、開口部２４はフード部２５によってすっぽりと覆われるものとなり、開口部２４の下縁部自体がフード部２５によって隠れてしまうものとし、しかもフード部２５、開口部２４自体は切り起こし形成後でも左右の保持枠部３の幅内に収まるようにしてある。尚、このような折込板面部２の第１傾斜面部２２、第２傾斜面部２３、開口部２４、フード部２５の形状は、例えばプレス成形用型枠による加工成形の際に同時に一体形成されるものとしてある。
【００１２】
このように形成された折込板面部２の２枚を、図５に示すように、裏表を逆にし且つ上下を逆にして配置させ、それぞれの第１傾斜面部２２同士および第２傾斜面部２３同士を接合させて互いに横方向にスライド可能となるように配置させることにより戸枠の左右幅寸法の大きさに対応調整できるものとしてある。そして、戸枠の左右幅寸法の大きさに対応調整した後に、２枚の折込板面部２の接合部同士を前後にバタつかないように連結させるための２枚折帯板状に形成された保持部材６１を備えている。すなわち保持部材６１は、図８（ｂ）に示すように、帯板を折返部６２を介して略Ｕ字形に折り曲げると共に、その一端を折曲部６３を介して外側に略くの字形に折り曲げて形成してある。
【００１３】
尚、目隠し用板体１の折込板面部２に使用される不透明体としては、着色または乳白色等の例えばポリプロピレン、ポリエチレン、ポリカーボネート等の熱可塑性樹脂、不透明加工されたガラス繊維等によって、いわゆる半透明状の肉薄例えば約１ｍｍ以下の肉厚とした板状体等としてある。
【００１４】
図４に示すように、保持枠部３は、戸枠の屋内側の縦框を咬持させるための略コ字枠状の縦框側保持アーム部３１を一側端に一体形成し、薄肉の折込板面部２の左右縁端部を保持するための略コ字枠状の幅狭な折込板面部側保持アーム部３２を他側端に一体形成した全体略Ｈ型を呈する短尺帯枠形状に形成してある。この折込板面部側保持アーム部３２の左右内壁面には縦方向に沿って互いに所定の間隔をおいて複数の取付係合部３３を備えることで折込板面部側保持アーム部３２に対する薄肉の折込板面部２の脱着を容易なものとしてある。
【００１５】
また、折込板面部側保持アーム部３２の左右側面に略Ｈ形の切込部３４を形成しておき、この切込部３４によって形成された相対峙する矩形面部を互いに内側に向けて折曲することにより板発条性を付与した山型状の取付係合部３３を形成してあり、折込部２１を介して山型状に形成された第１傾斜面部２２および第２傾斜面部２３を山型状の取付係合部３３に合致係合させるべく折込板面部側保持アーム部３２のコ字枠内に横方向から挿入させることで第１傾斜面部２２および第２傾斜面部２３自体を弾発的に圧接保持させるものとしてある。
【００１６】
そしてまた、戸枠の屋内側の縦框が幅狭な場合でも当該縦框に保持枠部３が容易に取り付けられるようにするために、縦框側保持アーム部３１のコ字枠内には、略コ字枠状のスペーサ枠部４が例えば両面粘着テープ材５を介在させて、または接着等により固定配置してある。すなわちスペーサ枠部４は、縦框の外形状に対応すべく縦框側保持アーム部３１のコ字枠内径サイズよりも小さい内径を有するコ字枠状の縦框側嵌合用側面部４１と、縦框側嵌合用側面部４１の上下両端部に横方向に突出形成され、縦框側保持アーム部３１のコ字枠内にて左右に所定の間隙を空けて保持固定させるものとしたセパレータ鍔部４２とを備え、縦框側嵌合用側面部４１のコ字枠背面側には接着剤を塗布するかあるいは表面に剥離紙を貼着させた両面粘着テープ材５を貼着してある。これによりスペーサ枠部４のコ字枠状の縦框側嵌合用側面部４１内に戸枠の屋内側の縦框を隙間なく嵌合咬持させることで縦框側保持アーム部３１自体をガタつくことなくしっかりと固定させるようにしてある。
【００１７】
尚、戸枠の屋内側の縦框が幅広な場合では、スペーサ枠部４を使用しないで保持枠部３のみを使用すれば良い。さらに戸枠の屋内側の縦框が縦框側保持アーム部３１のコ字枠内幅よりも幅広な場合では、縦框側保持アーム部３１に対してスペーサ枠部４の縦框側嵌合用側面部４１のコ字枠背面側を外側に向けて嵌め込み、当該コ字枠背面側に貼着した両面粘着テープ材５または塗布した接着等によって縦框に固定させれば良い。すなわち、スペーサ枠部４背面に両面粘着テープ材５を貼着しておくことで、戸枠の縦框の突部の幅員が大きい場合には内法幅員が大きい保持枠部３によって、同様に戸枠の縦框の突部の幅員が小さい場合には内法幅員が小さくなるよう保持枠部３に両面粘着テープ材５を介在させて嵌め合わせたスペーサ枠部４によって、さらに戸枠の縦框に突部がない場合には、保持枠部３に逆向きに嵌め合わせたスペーサ枠部４背面の両面粘着テープ材５によって夫々の態様で装着可能にしてあり、このように種々な取付形態を選定して取付けることができるようにしてある。
【００１８】
尚、図示による説明を省略するが、保持枠部３の他の例として、中央に横長のガイド用長孔を形成した帯板状の取付基部と、この取付基部の一側端に二股となって一体形成して縦框内周縁部を咬持させる略コ字形を呈する保持アーム部とから形成し、目隠し用板体１の例えば左右の縁端部における上部と下部との合計４箇所にネジ孔を形成し、このネジ孔に対し取付基部のガイド用長孔をあてがっておき、これにネジ体を挿入させておいてからネジ孔に捩じ込むことで保持枠部３が取り付けられるようにしても良い。
【００１９】
また、図６に示すように、折込板面部２の開口部２４同士およびフード部２５同士の適数を合致させることにより複数の折込板面部２を上下方向に連結可能にして目隠し用板体１全体の大きさを拡張することで戸枠の上下幅寸法の大きさに対応調整できるものとしてある。そして、複数の折込板面部２の略縁端部同士を連結させる２枚折帯板状に形成された保持部材５１を備えている。すなわち保持部材５１は、図８（ａ）に示すように、帯板を折返部５２を介して略Ｕ字形に折り曲げると共に、その一端を折曲部５３を介して略くの字形に折り曲げて形成してある。そして図７、図９に示すように、複数の折込板面部２の第１傾斜面部２２および第２傾斜面部２３の複数を接合させて開口部２４同士およびフード部２５同士を合致させておいてから、合致した第１傾斜面部２２縁端部側からフード部２５にかけて保持部材５１を嵌挿して第１傾斜面部２２同士を折返部５２を介して咬持させ且つ折曲部５３を折込板面部２の折込部２１に圧接保持させることで複数の折込板面部２の縁端部同士を接合可能にしてある。
【００２０】
尚、保持部材５１を逆に使用し、合致したフード部２５先端部から第１傾斜面部２２にかけて保持部材５１を嵌挿してフード部２５同士を折返部５２を介して咬持させ且つ折曲部５３を折込板面部２の折込部２１に圧接保持させるようにしても良い。
【００２１】
複数の折込板面部２を上下方向に連結させる具体的な組合わせとしては、例えば１５個の折込部２１を有する折込板面部２が３枚と、７個の折込部２１を有する折込板面部２が１枚とで片面を構成し、例えば両面に使用することで１５個の折込部２１を有する折込板面部２が合計６枚と、７個の折込部２１を有する折込板面部２が合計２枚となる。このとき、縦方向の組綴じが片面６個で上下４個となり、例えば両面に使用すれば予備として２個の折込部２１を含む合計１８個となる。また、横方向の組綴じが片面３個で左右６個となり、例えば両面に使用すれば予備として２個の折込部２１を含む合計８個となる。折込板面部２の桟寸は、１５個の折込部２１の場合では、縦３０ｍｍ×１５＋１５ｍｍ＝４６５ｍｍとなる大型サイズと、７個の折込部２１の場合では、縦３０ｍｍ×７＋１５ｍｍ＝２２５ｍｍとなる小型サイズとが形成される。折込板面部２の型寸は、１５個の折込部２１の場合では、縦２６ｍｍ×１５＋１３ｍｍ＝４０３ｍｍとなる大型サイズと、７個の折込部２１の場合では、縦２６ｍｍ×７＋１３ｍｍ＝１９５ｍｍとなる小型サイズとが形成される。これによって例えば折込板面部２の組立サイズは、縦２６ｍｍ×１４×３＋１９５ｍｍ＝１２８７ｍｍとなる。
【００２２】
次に以上のように構成された実施の形態についての組付、使用の一例を説明するに、戸枠の左右幅寸法の大きさに対応すべく目隠し用板体１全体の左右方向の大きさを拡張するために、図１、図５に示すように、例えば左右２枚の折込板面部２同士を裏表を逆にし且つ上下を逆にして配置させ、それぞれの第１傾斜面部２２同士および第２傾斜面部２３同士を合致した状態で互いに横方向にスライド可能となるように配置させる。そして、戸枠の左右幅寸法の大きさに対応調整した後に、前面側または後面側のフード部２５から折込板面部２の接合部同士にかけて２枚折帯板状に形成された保持部材６１を嵌込む。このときフード部２５は合致される開口部２４を中央にしてそれぞれ反対側に位置し、しかも互いに上下逆向状態となって相対峙して配置されるため、左右の目隠し用板体１が互いに内側にスライド移動しても両フード部２５は互いに干渉しないのである。
【００２３】
接合配置させた左右の折込板面部２外側の縁端部に適当な間隔をおいて複数の保持枠部３を装着させる。この際、折込部２１を介して山型状に形成された折込板面部２の第１傾斜面部２２および第２傾斜面部２３を折込板面部側保持アーム部３２のコ字枠内に横方向から挿入させ、山型状の取付係合部３３に合致係合させて第１傾斜面部２２および第２傾斜面部２３自体を圧接保持させる。このときフード部２５の外壁面は折込板面部側保持アーム部３２の外壁面と略面一の状態に配置され、折込板面部２から外側に突出しない状態となる。保持枠部３の縦框側保持アーム部３１のコ字枠内にはスペーサ枠部４の縦框側嵌合用側面部４１を例えば両面粘着テープ材５、接着等により固定配置させ、縦框側嵌合用側面部４１のコ字枠内に戸枠の屋内側の縦框を隙間なく嵌合咬持させることで縦框側保持アーム部３１をガタ付くことなくしっかりと固定させる。
【００２４】
また、戸枠の上下幅寸法の大きさに対応すべく目隠し用板体１全体の上下方向の大きさを拡張するために複数の折込板面部２同士を上下に連結させる。この場合には、図７に示すように、複数の折込板面部２の第１傾斜面部２２および第２傾斜面部２３の適数を接合させて開口部２４同士およびフード部２５同士を合致させておく。そして、合致した第１傾斜面部２２の例えば左右縁端部側から２枚折帯板状に形成された保持部材５１を嵌挿させて第１傾斜面部２２同士を咬持させることで複数の折込板面部２の縁端部同士が連結されるのである。尚、必要に応じて、保持部材５１を逆さにして、合致したフード部２５先端部から第１傾斜面部２２にかけて嵌挿し、フード部２５同士を折返部５２を介して咬持させ且つ折曲部５３を折込板面部２の折込部２１に圧接保持させる。
【００２５】
こうして、網戸に目隠し用板体１が装着されることにより屋内が隠蔽され、屋外から網戸ごしに屋内が見えずプライバシーが保たれるのである。しかもこのように網戸の戸枠に目隠し用板体１を装着した状態でガラス戸を常時開けておきさえすれば、目隠し用板体１の複数のフード付開口部Ｐにより、屋内をフード部２５によって隠しながら開口部２４を介して屋内の換気や屋外との通気を容易に行わせるのである。
【００２６】
【発明の効果】
本発明は以上のように構成されているために、戸枠に網面を張着して成る網戸において、フード付開口部Ｐを備えた不透視体自体の簡単な変形構成によりプライバシーを保護しながら換気性、通気性、採光性等を可能にさせ、また従来のようにすだれ体を取り付けるための溝枠部を連設したり、すだれ縁押さえを被着させたりする等の複雑な構造としなくても一般に使用されている網戸に対して戸枠の屋内側の左右両縦框間に容易でしかも戸枠の縦横の大きさに対応調整して透視不可能な目隠し用板体１を取り付けることができる。また、従来の如く不透視体のフード部２５が網面に直接当ってしまうことがなくしっかりと戸枠に保持することができる。
【００２７】
すなわちこれは本発明が、板片に並列配置した複数段の折込部２１を交互に逆向きに折り込むことにより第１傾斜面部２２、第２傾斜面部２３それぞれを交互に連続して成る蛇腹状の折込板面部２と、折込板面部２の各第１傾斜面部２２もしくは各第２傾斜面部２３のいずれかに切り起こし状に突出して成るフード付開口部Ｐとを形成したからであり、これにより、屋内を隠しながら屋内の換気や屋外との通気、さらには屋外から屋内への光の採光等を容易に行うことができる。しかも、目隠し用板体１のフード付開口部Ｐ自体が簡易な構造であるから安価な目隠し装置を提供することができる。
【００２８】
フード付開口部Ｐは、折込板面部２における折込部２１に形成された折曲縁から第１傾斜面部２２もしくは第２傾斜面部２３のいずれかの面内を折込板面部２自体に平行となるように切り起こすことによりフード部２５が形成されているので、目隠し用板体１自体の左右両縦框間への嵌挿においてフード部２５が邪魔にならずに容易に目隠し用板体１を装着させることができ、フード部２５の網面に対する当接突っ掛かりを防止することができる。
【００２９】
折込板面部２の左右両縁端部には、戸枠の屋内側の左右両縦框に装着されるスライド着脱式の保持枠部３を備えると共に、保持枠部３は、戸枠の屋内側の縦框を咬持させる略コ字枠状の縦框側保持アーム部３１と、第１傾斜面部２２および第２傾斜面部２３に弾発的に圧接保持させる山型折曲状の複数の取付係合部３３を備えて一体形成した略コ字枠状の折込板面部側保持アーム部３２とを有する全体略Ｈ型帯枠形状を呈して成るので、目隠し用板体１自体を戸枠の屋内側縦框に容易に取り付けることができる。しかも保持枠部３の折込板面部側保持アーム部３２に対する折込板面部２の脱着も容易に行なえる。
【００３０】
２枚の折込板面部２を裏表且つ上下を逆向きにして配置させ、それぞれの第１傾斜面部２２同士および第２傾斜面部２３同士を合致させるようにして互いに横方向にスライド可能に接合配置させたので、目隠し用板体１自体を戸枠の左右幅寸法の大きさに対応調整して設置することができる。
【００３１】
折込板面部２同士の接合位置における前面側または後面側のフード部２５先端部から合致した第１傾斜面部２２同士もしくは第２傾斜面部２３同士にかけて嵌挿配置されて第１傾斜面部２２同士もしくは第２傾斜面部２３同士を圧接固定させる２枚折帯板状の保持部材６１を備えたので、接合位置における折込板面部２同士の前後のバタつきを防止できる。
【００３２】
複数の折込板面部２を開口部２４同士およびフード部２５同士の適数を合致させて上下方向に連結可能にしたので、目隠し用板体１自体を戸枠の上下幅寸法の大きさに対応調整して設置することができる。
【００３３】
折込板面部２同士の連結位置における合致した第１傾斜面部２２縁端部もしくはフード部２５先端部に嵌挿配置されて第１傾斜面部２２同士もしくはフード部２５同士を咬持させる２枚折帯板状の保持部材５１を備えたので、複数の折込板面部２の縁端部同士をしっかりと保持固定させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention provides, for example, in a general residential house such as a condominium or a detached house, a blindfold plate that cannot see through the interior from the outside can be attached from the indoor side to a screen door formed by attaching a net surface to a door frame. Related to a blindfold device.
[0002]
[Prior art]
Conventionally, as a blindfolding device for this type of screen door, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 54-119249, a left and right vertical frame of a door frame has been used in a screen door having a net frame attached to a door frame. There is a configuration in which a plurality of band-shaped opaque bodies are inserted and stacked so as to be stacked in the vertical direction so as to cover the entire mesh surface.
[0003]
Further, as disclosed in Japanese Utility Model Application Laid-Open No. 56-148500, a groove frame having a substantially inverted F-shaped cross section is continuously provided on the inner peripheral edge of a door frame having a net body stretched on the outer surface. The end of the blind body is interposed inside the portion, and the blind frame holder is attached to the outer surface of the end of the blind body so as to be fitted into the groove frame portion, and the blind frame is held on the door frame by holding the blind edge holder. There is a configuration as described above.
[0004]
[Problems to be solved by the invention]
However, in the above-mentioned conventional example, in a blindfolded screen door disclosed in, for example, Japanese Utility Model Application Laid-Open No. 54-119249, the plurality of strip-shaped opaque bodies themselves are blind boards, and thus have no ventilation or air permeability at all. Also, a plurality of strip-shaped opaque bodies are simply inserted between the left and right vertical stiles so as to be vertically stacked, and there is nothing supporting the opaque body on the mesh side. As a result, the opaque body itself directly hits the net surface, which is deformed or damaged. Further, when the opaque body itself has an opening with a hood, the hood itself generally projects laterally from the upper edge of the opening and curves downward to project toward the mesh surface. Since the depth length is large as a whole, there is a problem that the hood portion of the opaque body directly hits the net surface in a small space between the opaque body and the screen door.
[0005]
On the other hand, in the blind screen door disclosed in Japanese Utility Model Application Laid-Open No. 56-148500, a groove frame having a substantially inverted F-shaped cross section is continuously provided on the inner peripheral edge of the door frame, or is received on the outer surface of the end of the blind body. A very complicated structure, such as attaching a bordered blind edge holder, results in an expensive screen door, and a structure for attaching such a blind body to a commonly used screen door. However, there is a problem that the versatility for screen doors is poor, for example, it is impossible to provide a screen door.
[0006]
Accordingly, the present invention has been made in view of the above-described circumstances that have existed in the past. In a screen door having a screen frame attached to a door frame, a simple opaque body having an opening with a hood is used. Ventilation, ventilation, daylighting, etc. are made possible while protecting privacy by the modified configuration, and a groove frame for attaching a blind body is attached continuously, and a blind edge holder is attached as usual. It is not possible to easily see through the door frame between the left and right vertical frames on the indoor side of the door frame, and adjust it to the vertical and horizontal size of the door frame even if it does not have a complicated structure such as The present invention provides a blindfolding device capable of attaching a blindfolding plate body and holding the hood portion of the opaque body firmly to the door frame without directly hitting the net surface as in the related art. And

Further, unlike the conventional case, the hood portion 25 of the opaque body can be securely held on the door frame without directly hitting the net surface.
[0027]
That is, this is because the present invention is configured such that a plurality of folded portions 21 arranged in parallel on a plate piece are alternately folded in the opposite direction to alternately continuously connect the first inclined surface portion 22 and the second inclined surface portion 23, respectively. This is because the folded plate surface portion 2 and the hooded opening portion P that is cut and raised and protruded in either the first inclined surface portion 22 or the second inclined surface portion 23 of the folded plate surface portion 2 are formed. In addition, it is possible to easily perform indoor ventilation and ventilation with the outdoors while concealing the interior, and light from the outdoors to the indoors. Moreover, since the hooded opening P of the blindfold plate 1 has a simple structure, an inexpensive blindfolding device can be provided.
[0028]
The opening P with a hood is parallel to the folded plate surface portion 2 itself within the plane of the first inclined surface portion 22 or the second inclined surface portion 23 from the bent edge formed in the folded portion 21 in the folded plate surface portion 2. The hood portion 25 is formed by cutting and raising as described above, so that the hood portion 25 can be easily inserted without interfering with the hood portion 25 when the blind plate 1 itself is inserted between the left and right vertical frames. The hood 25 can be prevented from abutting against the net surface.
[0029]

And a plurality of mountain-shaped bent attachments which elastically press and hold the first inclined surface portion 22 and the second inclined surface portion 23 on a substantially U-shaped vertical frame side holding arm portion 31 for holding the vertical frame. Since it has an overall substantially H-shaped frame shape having a substantially U-shaped frame-shaped folded plate surface portion side holding arm portion 32 integrally formed with an engagement portion 33, the blindfold plate 1 itself is used as a door frame. It can be easily attached to the indoor vertical frame. In addition, the folding plate surface 2 can be easily attached to and detached from the folding plate surface side holding arm 32 of the holding frame 3.
[0030]
The two folded plate surface portions 2 are arranged upside down and upside down, and the first inclined surface portions 22 and the second inclined surface portions 23 are joined so as to be slidable in the lateral direction so as to match each other. Therefore, the blindfold plate 1 itself can be installed so as to correspond to the size of the left and right width of the door frame.
[0031]
The first inclined surface portions 22 or the second inclined surface portions 23 are fitted and arranged from the front end portion or the front end portion of the hood portion 25 at the joint position of the folding plate surface portions 2 to the first inclined surface portions 22 or the second inclined surface portions 23. Since the holding member 61 in the form of a two-folded band plate for fixing the two inclined surface portions 23 to each other by pressing is provided, it is possible to prevent front and rear fluttering of the folded plate surface portions 2 at the joining position.
[0032]
Since the plurality of folding plate surface portions 2 can be connected in the vertical direction by matching an appropriate number of the opening portions 24 and the hood portions 25, the blindfold plate 1 itself corresponds to the size of the vertical width of the door frame.
