Description

【０００１】
【産業上の利用分野】
本発明は、折たたみサッシに関するものである。
【０００２】
【従来の技術】
一対の障子を召合せ框において互いに回転自在に枢着して中折れサッシ構成単位体を構成し、該中折れサッシ構成単位体の一方の障子の召合せ框に対向する縦框側に吊車を止着し、該吊車に備えたローラを、上枠に設けた案内レール上に転動自在に載置して、前記縦框側を見付け方向に押圧することによってローラが案内レールに沿って移動し、枢着部においてたたまれて一対の障子が互いに重なり合うようにした構造の折たたみサッシは具体例を挙げるまでもなく公知である。
【０００３】
【発明が解決しようとする課題】
前記従来例は、ローラを案内レールの中間部に位置させることによって半開き状態を得られるが、ローラは、案内ローラ上を転動して移動できる状態におかれているので（すなわち、ローラの移動停止手段が施されていないため）、風などによって容易に移動し、半開き状態を維持する手段が望まれていた。
【０００４】
本発明は、斯様な状況に鑑み創案したものである。
【０００５】
【課題を解決するための手段】
一対の障子を召合せ框において互いに回転自在に枢着して中折れサッシ構成単位体を構成し、該中折れサッシ構成単位体の一方の障子の前記召合せ框に対向する縦框側に吊車を止着し、該吊車に備えたローラを、上枠に設けた案内レール上に転動自在に載置した折たたみサッシにおいて、前記一方の障子の前記縦框側にばねによる付勢に抗して降下する係止片を上方向に突設し、該係止片の上端が接する下面に、前記案内レールに沿う方向の両端から中央の前記係止片の受止穴に至るに従って漸次下方に突出するように傾斜させた一対の傾斜面を備えた規制片を、前記係止片の移動路上にして前記上枠の中間部適所に止着し、前記受止穴の前記案内レールの長手方向に沿う方向に相対する内壁を、前記係止片が係止する受止縁とし、障子閉塞時に係止片が移動する方向側の一方の受止縁を、他方の受止縁より下方に突出させたものである。
【０００６】
【作用】
縦框側を見付け方向に押圧すると、吊車のローラが案内レールに沿って転動、移動し、この結果、中折れサッシ構成単位体は、障子の枢着部が、見込み方向に窓枠より突出して中折れ状態となり、この中折れ状態（全開放状態）に移行する際、或いは、中折れ状態から原位置（閉塞状態）に移行する際、係止片の上端が係止片の移動路上の適所に配した規制片の傾斜状の下面に摺接して前記下面に沿って移動して受止縁部に受止められて移動が規制され、この係止片の移動の規制により、ローラの案内レールに沿う移動が中断され、中折れ障子の半開き状態を得られ、該半開き状態はばねの付勢によって維持される。ばねの付勢に抗して係止片を降下させて受止縁位置から外すことにより、ローラの案内レールに沿う移動、すなわち、障子の閉塞操作が行われる。
【０００７】
【実施例】
図面は本発明に係る折たたみサッシの一実施例を示し、図１は一部欠截正面図、図２は図１のＸ−Ｘ線断面図、図３は操作部の正面図、図４は図３の横断面図、図５は吊車の配置関係を示す略示正面図、図６は第二実施例の一部欠截正面図、図７は規制片の略示図である。
【０００８】
実施例の折たたみサッシは、互いに回転自在に接続した一対の障子１，１´で構成した一対の折たたみサッシ構成単位体Ａ，Ａ´を窓枠Ｂに組付けて構成し、折たたみサッシ構成単位体Ａ，Ａ´は、前記窓枠Ｂを構成する縦枠２ｃ側の一方の障子１´の縦框３´ｃを図示省略した蝶番を介して前記縦枠２ｃに接続し、他の一方の障子１の縦框３ｃに接続蝶番４を介して操作框５を接続し、操作框５に止着した吊車６のローラ７を、前記縦枠２ｃ，２ｃおよび下枠２ｂと共に前記窓枠Ｂを構成する上枠２ａに設けた案内レール８に転動（走行）自在に載置して構成したものである。すなわち、実施例は、縦框３ｃ側に操作框５を接続し、この操作框５に吊車６等の本発明の主要部材を組付けたものであるが、操作框５を省略して実施例の吊車６と違う構造の吊車を縦框に組付けて本発明を適用しても良い。「請求項１」で「縦框側」としてあるのはこの趣旨を含めてのことである。
【０００９】
吊車６は、主体ブロック９と該主体ブロック９の一端に取付け片１０を連設して成る吊車本体１１の主体ブロック９に、一対の前記ローラ７，７を回動支軸１２によって組付ける一方、係止片１３を縦動可能に組付けて構成したもので、吊車本体１１の取付け片１０を前記操作框５の部片５ａに裏板１４を利用して止着して主体ブロック９およびこれに回動自在に枢着したローラ７を操作框５乃至障子１より上方に突出させ、ローラ７を前記案内レール８上に転動自在に載置して操作框５乃至障子１を吊持するものである。
【００１０】
この吊車６を構成する主体ブロック９には上部側を大径部１５´とし、該大径部１５´の上側開口端を小径にした貫通孔１５を縦設し、該貫通孔１５に係止片１３を貫通させて前記の通り主体ブロック９に組付けてある。
【００１１】
係止片１３は、棒杆状の主体杆１３Ａの上端にキャップ体１３ａ装着して構成し、キャップ体１３ａのフランジ部１３ａ´が、貫通孔１５の前記大径部１５´内を離脱することなく縦動するようにして主体ブロック９に組付けたもので、フランジ部１３ａ´と貫通孔大径部１５´の底面との間にはコイルばね１６を介装し、該コイルばね１６により上端側すなわちキャップ体１３ａ側が主体ブロック９より突出する方向に付勢され、キャップ体フランジ部１３ａ´の前記上側開口端に対する接触係止によって主体ブロック９からの突出量が規制され、一定の長さ分だけ主体ブロック９より突出するようにしてある。
【００１２】
主体ブロック９の下端より突出する係止片１３（主体杆１３Ａ）の下端部に、前記操作框５に挿入した仲介杆１８を連結片１７を介して取付け、仲介杆１８の下端部に、操作框５の案内側面に突出した摘み１９´を備えた操作レバー１９を止着し、この操作レバー１９の前記摘み１９´は、操作框５の適宜の高さ位置に止着した案内枠２０の縦長窓口２１に係合し、該窓口２１内を縦動するように組付けてある。
【００１３】
また、吊車６に組付けた前記係止片１３の前記案内レール８に沿う移動路上の適所には、障子の開閉操作中に（吊車６の移動中）係止片１３（主体杆１３Ａ）の上縁が接離する規制片２２を前記上枠２ａに止着（実施例では螺子止め）して突設してある。
【００１４】
規制片２２は、案内レール８の長手方向に沿う方向（前記移動路）の両端から中央方向に漸次下方向に突出する一対の傾斜面２３Ａ´，２３Ａ´´で成る下面２２´を備え、この下面２２´の、下方向に最も突出した中央部には、受止穴２３Ａを設け、該受止穴２３Ａの、前記案内レールの長手方向に相対する内壁を前記係止片１３（主体杆１３Ａ）の上端が係止して、ローラ７（吊車６）に伴う係止片１３の移動を規制する受止縁２３，２３´と成し、障子閉塞時に係止片１３が移動する側の一方の受止縁２３を他方の受止縁２３´より下方に突出させてある。
【００１５】
しかして、操作框５を障子開放方向又は閉塞方向に押圧すると、ローラ７が転動して案内レール８に沿って移動し、前記の開放（折りたたみ状態）又は閉塞が行われ、この操作中、コイルばね１６で突出方向に付勢された係止片１３（主体杆１３Ａ）の上端は、該係止片１３の移動路上にして上枠２ａの適所に突設した規制片２２の下面２２´に摺接し、かつ、該下面２２´の傾斜状形態によって円滑に移動し、受止縁２３位置に移動し、これに受止されて移動を規制され障子の半開放状態が維持される。
【００１６】
そして、適宜の高さ位置に配した操作レバー１９を摘み１９´を摘んでコイルばね１６に抗して降下させると、係止片１３上端は受止縁２３位置から外れ、この状態を維持させて操作框５を移動させることによって障子の開放又は閉塞操作が再び行われる。
【００１７】
図６で示す第二実施例のものは、第一実施例の主体ブロック９に設けた貫通孔１５に代えて上面側開口のスリット２４を設け、該スリット２４に係止片１３を係合して支軸２５によって前記主体ブロック９に回動可能に枢着し、受止縁２３を構成する受止穴２３Ａを出入する部片１３´部の下側の係止片１３部に透孔２６を設け、該透孔２６に、主体ブロック９に挿通した縦動杆１３Ａ´（第一実施例の主体杆１３Ａに対応）の上端に設けた支承枠２７の相対する立上り部片に架設したピン２８を貫通させて、連結片１７に取付けた前記縦動杆１３Ａ´と係止片１３を互いに組付け、前記支承枠２７と主体ブロック９との間に、支承枠２７すなわち前記ピン２８によって支承枠２７に接続した係止片１３（の部片１３´）を受止穴２３Ａに係合する方向（係止片１３が規制片２２に圧接する方向）に付勢するコイルばね１６を前記縦動杆１３Ａ´に巻回して介在させて構成し、第一実施例と同様に、コイルばね１６の作用により係止片１３（の部片１３´）上端は規制片２２の下面２２´に摺接して移動して受止穴２３Ａに係合して障子の移動を規制し、操作レバー１９を操作することにより、移動規制状態が解放されるようにしてある。
【００１８】
なお、第二実施例のその他残余の点は第一実施例と同様である。
【００１９】
なお、前記の通り、受止穴２３Ａの一方の受止縁２３´より他方の受止縁２３を下方に突出させておくと、係止片１３を一方の受止縁２３´から他方の受止縁２３方向へと移動させたとき、係止片１３には上方に向けてばね付勢されているので係止片１３は受止穴２３Ａを飛び越えることなく他方の受止縁２３に係止され、障子の移動が規制される。実施例は、この他方の受止縁２３は障子閉塞側に、一方の受止縁２３´を開放側に配して構成したものである。
【００２０】
【発明の効果】
本発明は前記の通りの構成であるから、半開き状態を確実に維持する折たたみサッシを提供でき、また、規制片の下面の傾斜形状によって係止片を円滑に移動させて受止縁位置にして障子の半開き状態を自動的に得ることができる。

[0006]
[Action]
When the downside is pressed in the direction of finding, the roller of the suspension wheel rolls and moves along the guide rail, and as a result, the folding sash component unit has the shoji pivoting part protruding from the window frame in the expected direction. The upper end of the locking piece is located on the moving path of the locking piece when the middle folding state (full open state) or when shifting from the middle folding state to the original position (closed state). The roller is slidably brought into contact with the inclined lower surface of the restricting piece arranged at an appropriate position, moves along the lower surface and is received by the receiving edge, and the movement is restricted. The movement along the rail is interrupted, and a half-open state of the folding shoji is obtained, and this half-open state is maintained by the bias of the spring. The roller is moved along the guide rail, that is, the shoji is closed, by lowering the locking piece against the spring bias and removing it from the receiving edge position.
