【発明の属する技術分野】
本発明は、引き戸の外側に配置し、該引き戸と連動して左右両開き式に開閉可能とした巻取式網戸に関するものであり、更に具体的には、上記引き戸と巻取式網戸とを連動させあるいはその連動を解除するためのラッチ機構を備えた巻取式網戸に関するものである。
【0002】
【従来の技術】
引き違い式に開閉する引き戸によって開かれる左右の開口部をそれぞれ遮蔽する巻取式網戸を設置する場合、図6のA,Bに示すように、引き戸における建物外側の開口枠の左右の縦枠に、引き戸の開閉操作に連動する巻取式網戸をそれぞれ設置することが考えられる。そして、これらの巻取式網戸においては、外側の引き戸に対する網戸の可動框の連動を、人の出入りのために必要に応じて解除できるようにすることが要求され、通常は室内側から上記可動框に設けたラッチを引き戸の縦枠に設けたラッチピースと係脱できるようにしている。
【0003】
ところが、上記巻取式網戸において、上記ラッチを可動框または引き戸の操作により引き戸のラッチピースに自動係合可能にすると、室外側での誤った可動框または引き戸の操作により、該ラッチがラッチピースに係合してしまい、室外側からは網戸の開閉操作を行うことができなくなるという問題がある。
一方、上記ラッチは、簡単な構造で故障することがなく、引き戸または可動框の操作によりラッチピースに対して確実に自動係合すると共に、ラッチが自動係合しない位置にも容易に保持させ得ることが望まれる。
【0004】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、簡単な構造によって上記ラッチを室内外のいずれの側からも操作できるようにした巻取式網戸を提供することにある。
本発明の他の課題は、簡単な構造によって、引き戸または可動框の操作によりラッチがラッチピースに対して確実に自動係合するようにした巻取式網戸を提供することにある。
本発明の他の課題は、簡単な構造により、上記ラッチをラッチピースに対して自動係合しない位置に容易に保持できるようにした巻取式網戸を提供することにある。
【0005】
【課題を解決するための手段】
上記課題を解決するため、本発明は、引き戸の外側に該引き戸と連動して左右両開き式に開閉可能とした巻取式網戸であって、網戸枠の上下の横枠に沿ってスプリングを巻取用の駆動源とするネットを開閉自在とし、該ネットの開閉操作用の可動框の上下の摺動部材を網戸枠の上下の横枠にガイドさせながら上記ネットを開閉するようにした巻取式網戸において、上記可動框に引き戸の縦枠に設けたラッチピースと係脱自在に係合してその係合により可動框を引き戸の移動に追随させるラッチを設け、そのラッチを可動框または引き戸の操作によりラッチピースに自動係合可能にすると共に、該ラッチに室内外のいずれの側からも操作できる操作部を設け、上記可動框に設けたラッチを、該可動框の框材に沿って一定範囲内で上下に摺動自在に形成し、該ラッチの自重による下降位置を引き戸のラッチピースに自動係合可能な位置としたことを特徴とするものである。
【0006】
上記巻取式網戸のより具体的な構成においては、可動框のラッチと引き戸のラッチピースとは、引き戸と可動框との間に形成されたネットの非張設開口を閉じる方向に上記引き戸または可動框が移動するときに、ラッチピースがラッチを押し上げて相互に自動係合させるカム面を備えた構成とすることができ、また、ラッチを上動位置に係合保持する保持手段を設けて、そこで自動係合しないように保持可能とするのが適切である。
【0007】
上記構成を有する巻取式網戸は、引き戸または可動框を、それらの間に形成されたネットの非張設開口を閉じる方向に移動させ、それにより引き戸の縦枠と可動框が重なると、可動框に設けたラッチが引き戸に設けたラッチピースに自動係合し、その後は、引き戸を移動させる際にその縦枠に係合した網戸が引き戸に追随して移動することになる。そのため、室外側において引き戸または可動框を操作することにより、可動框のラッチが引き戸のラッチピースに係合してしまうこともあるが、ラッチはその操作部によって室内外のいずれの側からもラッチピースに対する係脱操作をできるので、引き戸によって形成された開口部の網戸を室内及び室外側から自由に開閉することができる。
【0008】
また、上記巻取式網戸における可動框に設けたラッチは、可動框の框材に沿って一定範囲内で上下に摺動自在に形成し、該ラッチがその自重による下降位置にある状態において、引き戸または可動框を、それらの間に形成されたネットの非張設開口を閉じる方向に移動させたときに、ラッチとラッチピースのカム面が相互に当接してラッチを押し上げたうえで、該ラッチがラッチピースの背後に係合するようにしているので、簡単な構造によってラッチをラッチピースに対して確実に自動係合させることができるばかりでなく、該ラッチを上動位置に係合保持させるだけの簡単な操作で、ラッチピースに対して自動係合しない状態に保持することもできる。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳細に説明するに、図1乃至図3は、本発明の巻取式網戸の一実施例を示しており、図中、2は略矩形状をなす網戸枠、4A,4Bは該網戸枠2内に左右両開き式に開閉自在に取り付けられた防虫網からなるネット、6A,6Bはそれぞれネット4A,4Bの端部に取り付けられた開閉操作用の可動框である。
なお、上記左右のネット4A,4Bに関連する構造は実質的に同一であるから、以下の説明においては、特に必要がなければネット4Aに関する構造についてのみ説明し、ネット4Bについての説明は補助符号を読み替えるものとして、それらの説明を省略する。
【0010】
上記ネット4A,4Bは、図1及び図2に示すように、それらの一端をそれぞれ上記網戸枠2における左右の縦枠8,10に取り付るとともに、他端をスプリング16を巻取用の駆動源とする巻取軸18A,18Bに固定しており、それらの巻取軸18A,18Bを、それぞれ可動框6A,6Bの框材22A,22B内に回転自在に収容することにより、上記ネット4A,4Bを繰り出し及び巻き取り可能に配設している。
【0011】
上記網戸枠2は、図1及び図2からわかるように、左右の縦枠8,10及び上下の横枠12,14により略矩形状に形成したもので、建物開口部にネジ止めあるいは接着テープ等の適宜手段により固定し得るようになっている。
【0012】
上記可動框6Aにおける框材22Aは、合成樹脂製又はアルミニウム等の金属製で一部に開口を有する筒状をなし、上記網戸枠2における上下の横枠12,14に沿って移動自在の上下の摺動部材24A,26Aを該框材22Aの上下端に連結し、該框材22A内において上記ネット4Aを巻き付けた巻取軸18Aの上下端を上下の摺動部材24A,26Aに回転自在に保持させ、框材22Aの上記開口からネット4Aを導出している。
【0013】
上記摺動部材24A,26Aは、網戸枠2における上下の横枠12,14を摺動して上記可動框6Aによるネット4Aの開閉操作を円滑に行うことができるようにするためのもので、更に具体的には、上記可動框6Aにおける框材22Aの上部に連結した摺動部材24Aは、上記框材22Aの上端に嵌着する本体32aに、上記網戸枠2における上部の横枠12のガイドレール12a上を転動する一対の転輪34aを備えた摺動部36aをねじ38aで取り付けることにより構成され、一方、上記框材22Aの下部に連結した摺動部材26Aは、上記下部の横枠14の長手方向両側に立設したガイド壁14aにガイドさせるべく、上記框材22Aの下端に嵌着している。
【0014】
上記網戸枠2における上部の横枠12の中央には、それぞれの可動框6A,6Bの移動範囲を上記横枠12の中央部を若干越えた位置まで許容する左右に可動のストッパ30を設けている。このストッパ30は、図1及び図3に示すように、可動框の上部の摺動部材24A(24B)が摺動する横枠12内に取り付けるストッパ本体30aの両側面に、上記ネット4Aの開閉方向に沿う長穴30bを穿設すると共に、該長穴30bに上記可動框の上部の摺動部材24A(24B)における転輪34aが当接する可動部材(ピン)30cを移動自在に遊嵌することにより形成したものである。
【0015】
上記巻取式網戸においては、その可動框6A,6Bに、図2及び図6のA,Bに示すように、外側の引き戸(障子)60の縦枠60A,60Bに設けたラッチピース41A,41Bに係脱自在に係合して、その係合により可動框6A,6Bを引き戸60の移動に追随させるラッチ42A,42Bを備えている。
このラッチ42A(42B)は、図4及び図5に明確に示すように、上記可動框6Aの框材22Aに沿って一定範囲内で上下に摺動自在に形成したラッチ本体43A(43B)を備え、このラッチ本体43Aに、框材22Aを囲んで室内外のいずれの側にも位置することにより、室内外のいずれの側からも昇降操作できる操作部を形成させている。
【0016】
また、このラッチ本体43Aには、ラッチ42Aを上動位置に保持する保持手段44Aを設けている。この保持手段44Aとしては、図1、図2及び図5に明瞭に示すように、框材22Aの長さ方向に沿って設けた取付溝23A内に、ねじ受け板45Aを嵌入し、このねじ受け板45Aとそれをカバーする固定板46Aとをねじ49Aで固定することにより、該固定板46Aを框材22Aに対して取付溝23Aに沿う上下方向に不動に固定し、一方、ラッチ本体43Aに上記固定板46Aを横切るように設けた当接部50Aを固定板46Aの上下部に形設したストッパ部47Aに当接させて、ラッチ本体43Aの上下移動範囲を制限すると共に、ラッチ本体43Aの当接部50A上に設けた弾片51Aを、ラッチ本体43Aの上動位置において、固定板46A内に突設した係合突部48Aに係合させるようにしている。
【0017】
上記ラッチ42A,42Bは、図7及び図8によって後述するように、ラッチ本体43A,43Bの自重による下降位置を前記引き戸60の縦枠60A,60Bに設けたラッチピース41A,41Bに自動係合可能な位置とし、一方、上記弾片51Aと係合突部48Aからなる保持手段44Aにより保持されるラッチ本体43Aの上動位置を、ラッチ42A,42Bがラッチピース41A,41Bに自動係合しない位置としている。
【0018】
そして、上記ラッチ42Aまたは42Bがラッチピース41Aまたは41Bに係合していないとき、そのラッチをラッチピースに対して自動係合させるため、上記ラッチ本体43A,43Bとラッチピース41A,41Bには、引き戸60と可動框6A,6Bとの間に形成されたネットの非張設開口を閉じる方向に上記引き戸と可動框を相対移動させたときに、ラッチピース41A,41Bがラッチ本体43A,43Bを押し上げて相互に自動係合させるカム面53a,54aを設けている。これらのカム面53a,54aの当接により押し上げられたラッチ本体は、ラッチピースがそのラッチ本体の下を通過した後に該ラッチピースの背後に自重で降下し、そのラッチピースの背後に係合することになる。
【0019】
また、上記框材22A,22Bと引き戸60の縦枠60A,60Bとの間には隙間が存在し、その隙間部分からのの侵入を防止する必要があるため、框材22A,22Bには、ブラシ、モヘアあるいは弾性薄片などからなる防虫シール55(図2参照)を設けているが、ラッチ本体43A,43Bが摺動する部分では該ラッチ本体43A,43Bが框材22A,22Bにおける防虫シールの部分を囲むことになるため、該防虫シールを設けることができなくなる。そのため、上記ラッチ本体43A,43Bにおける防虫シール55の延長線に近い位置には補助防虫シール56を装着する装着溝57を設けている。
なお、図中に示す符号28は可動框6A,6Bの衝突の勢いを緩和するための弾性緩衝材を示している。
【0020】
上記構成を有する巻取式網戸は、引き戸60または可動框6A,6Bを、それらの間に形成されたネット4A,4Bの非張設開口を閉じる方向に移動させ(図7のA)、それにより引き戸60の縦枠60A,60Bと可動框6A,6Bが重なる状態になると、ラッチ本体43A,43Bとラッチピース41A,41Bとに設けたカム面53a,54aの当接により、ラッチ本体が押し上げられ(図7のB)、更に移動が進行すると、該ラッチがラッチピースの背後に自重で落下し、ラッチ本体43A,43Bがラッチピース41A,41Bに自動係合することになる。
【0021】
その後は、引き戸60を移動させる際に、その縦枠60A,60Bに係合した網戸が引き戸60に引かれ、あるいは巻取軸18A,18B内のスプリング16によりネットが巻き取られながら、可動框6A,6Bが引き戸60に追随して移動することになる。例えば、図6のAに示すように、可動框6B引き戸60の縦枠60Bに係合してネット4Bが張設された状態から、同図のBに示すように引き戸60を開くと、その縦枠60Aに係止した可動框6Aを引き戸60の移動に追随させることができ、また、その過程で、あるいは、図6のBの状態にした後に、ラッチ本体43Aの上動によってラッチ42Aをラッチピース41Aから離脱させると、図6のBの状態においてネット4Aが可動框6A内に巻き込まれる。
【0022】
更に、上記ラッチ本体43A,43Bは、その操作部によって室内外のいずれの側からもラッチピース41A,41Bに対する係脱操作をできるので、室外側において引き戸または可動框を操作することにより、可動框のラッチが引き戸のラッチピースに係合しても、引き戸60によって形成された開口部のネットを室内及び室外側から自由に開閉することができる。
【0023】
また、上記巻取式網戸における可動框6A,6Bに設けたラッチ本体43A,43Bは、可動框の框材に沿って一定範囲内で上下に摺動自在に形成し、該ラッチ本体がその自重による下降位置にある状態において、引き戸60または可動框6A,6Bを、それらの間に形成されたネットの非張設開口を閉じる方向に移動させたときに、ラッチとラッチピースのカム面53a,54aが相互に当接してラッチ本体を押し上げたうえで、該ラッチ本体がラッチピースの背後に係合するようにしているので、簡単な構造によってラッチをラッチピースに対して確実に自動係合させることができるばかりでなく、該ラッチを保持手段により上動位置に係合保持させるだけの簡単な操作で、ラッチピースに対して自動係合しない状態に保持することもできる。
【0024】
なお、上述した実施例においては、本発明を、巻取軸18A,18Bをそれぞれ可動框6A,6Bの框材22A,22B内に回転自在に保持した巻取式網戸に適用した場合について記載したが、それに限定されず、網戸枠における左右の縦枠8,10にそれぞれ巻取軸を回転自在に保持させた巻取式網戸に適用することもできる。
【0025】
【発明の効果】
以上に詳述した本発明によれば、引き戸の外側に該引き戸と連動して左右両開き式に開閉可能とし、しかもその連動のためのラッチをラッチピースに自動係合可能にした巻取式網戸において、簡単な構造によりラッチを室内外のいずれの側からも操作することが可能になり、また、ラッチがラッチピースに対してその自重で確実に自動係合し、それを自動係合しない位置にも容易に保持することができる。
