Description

【0001】
【発明の属する技術分野】
本発明は、跳上式面格子落下防止装置に関するものである。
【0002】
【従来の技術】
面格子の上部を回動中心として回動する面格子を設けた跳上式面格子では、屋内側から面格子を屋外側に向けて押すと、面格子は上部の回動軸を中心に屋外側に回動し、庇状になる。この庇状の面格子を保持するものがなければ、面格子は自重で屋内側に向けて回動落下し、危険である。
【0003】
跳上式面格子では、庇状の開放状態を保持するものが少ないが、開放状態を維持するものとして突っ張り棒を用いるものもある。また、急に、面格子が落下するのを防止するものとして、面格子と枠体との間にダンパーを設けたものもある。
【0004】
【発明が解決しようとする課題】
跳上式面格子では、庇状の開放状態を保持するものがなければ危険であるし、突っ張り棒では任意の面格子の回動角度を維持することはできず、ダンパーを設けると高価となる。
【0005】
【課題を解決するための手段】
そこで、本発明は、上記の事情に鑑み、跳上式面格子では、庇状の開放状態を保持するものがなければ危険であるし、突っ張り棒では任意の面格子の回動角度を維持することはできず、ダンパーを設けると高価である。これ等の問題を解決すべく、面格子の上部を回動中心として回動する面格子を設けた跳上式面格子において、面格子内面中間部と面格子下方の下枠材との間に伸縮部材を設け、屋内側から面格子を開閉できるようにした跳上式面格子落下防止装置とした。
【0006】
また、本発明は、具体的には、伸縮部材は、パイプとパイプ内を摺動するラックギヤーと、ラックギヤーのラックと噛み合うクラッチとよりなる。
【0007】
【発明の実施の態様】
本発明を添付する図面に示す具体的な実施例に基づいて、以下詳細に説明する。
【0008】
図1において、面格子1は四角状枠内に嵌まり、四角状枠は縦枠材2と上枠材3と下枠材4とよりなる。
【0009】
面格子1の内面中間部に上部軸受5を固着し、上部軸受5に対向する下枠材4の箇所に下部軸受6に固着する。
【0010】
前記下部軸受6にパイプ7の基端を回転軸8を介して回動自在に設ける。このパイプ7にラックギヤー9を摺動自在に嵌め、ラックギヤー9の上端を回転軸10を介して前記上部軸受5に回動自在に設ける。
【0011】
ラックギヤー9のラック11と係合して面格子1の落下を防止するクラッチ12をパイプ7の上端部に設ける。
【0012】
図2の分解斜視図に示すように、四角筒状のパイプ7の基端部を回転軸8を介して下部軸受6に回動自在に設け、下部軸受6は下枠材4にビス(図示せず)で固定する。
【0013】
ラックギヤー9は、パイプ8に摺動自在に嵌まる四角柱状体で、一面にラック11が刻設してある。このラックギヤー9の上端部を回転軸10を介して上部軸受5に回動自在に設け、上部軸受5は面格子1内面中間部に固定する。
【0014】
クラッチ12は十字状の薄板の左右をパイプ7に外嵌めできるようにコ字状の抱持片15に形成し、上部を前記ラックギヤー9のラック11と係合できるように斜め前方に屈曲させた爪片14に形成する。パイプ7の上端部の左右にピン16を突設し、このピン16をクラッチ12の抱持片15の支持孔17に嵌め、ビス18をピン16に螺着して、クラッチ12をピン12の回りに回動自在に設ける。クラッチ12の爪片14が常時ラック11と係合できるように、爪片14を傾けるために若干屈曲させた板バネ19をクラッチ12の内面に設ける。面格子1を屋内側から押すと、面格子1は庇状に開く。操作片20を押す力を解除すると、板バネ19の力により爪片14はラック11と係合し、面格子1の開放状態を保持する。
【0015】
面格子1を押し上げる時は、クラッチ操作は不要(自動ロック)で、クラッチ操作は面格子1を下降させる時のみ必要である。
【0016】
クラッチ12は十字状の薄板の左右をパイプ7に外嵌めできるようにコ字状の抱持片15に形成し、上部を前記ラックギヤー9のラック11と係合できるように斜め前方に屈曲させた爪片14に形成する。パイプ7の上端部の左右にピン16を突設し、このピン16をクラッチ12の抱持片15の支持孔17に嵌め、ビス18をピン16に螺着して、クラッチ12をピン16に回りに回動自在に設ける。クラッチ12の爪片14が常時ラック11と係合できるように、爪片14を傾けるために若干屈曲させた板バネ19をクラッチ12の内面に設ける。面格子1を屋内側から押すと、面格子1は庇状に開く。操作片20を押す力を解除すると、板バネ19の力により爪片14はラック11と係合し面格子1の開放状態を保持する。
【0017】
面格子1を押し上げる時は、クラッチ操作は不要(自動ロック)で、クラッチ操作は面格子1を下降させる時のみ必要である。
【0018】
面格子1を上昇させる時は、図3に示すように、クラッチ12の爪片14がラックギヤー9のラック11と係合した状態で、面格子1を屋外側に向けて押すと面格子1は上昇する。面格子1を押すことを止めると、爪片14がラック11に係合しているのでその状態を保持する。したがって、面格子1の開度を任意の状態に保持できる。
【0019】
面格子1を下降させる時は、図4に示すように、クラッチ12の操作片20を板バネ19の付勢力に抗して押し下げると、爪片14とラック11との係合が外れて面格子1の下降が可能となる。操作片20の押し下げを解除すると、板バネ19の付勢力により爪片14はラック11と係合する。
【0020】
なお、面格子1を上昇させる際、ラックギヤー9がガイドパイプ7により抜け外れないように図示してないが、基端を大径のストッパーにすればよい。
【0021】
この伸縮部材は、面格子の中央に一個だけ設ける場合と、面格子の両端に二個設ける場合とがある。
【0022】
面格子1は上枠材3に回動軸21を介して回動可能に設けられている。面格子1が四角状枠に閉まってしまう際、ゆっくり閉まるように、図5に示す緩衝用巻きバネを、図1のように設ける。この緩衝用巻きバネは閉まってしまう際、抵抗するように設定する。
【0023】
本発明の面格子は、種々の用途の面格子に使用できる。
【0024】
図6に示す中央に伸縮部材24を配置した日除兼用開閉式ルーバー23、図7に示す開閉式格子26、図8に示す庇兼用開閉式アートテント25、図9に示す庇兼用開閉式採光パネル27、図10に示す跳上げ、巻上げ併用CMテント28、図11に示す跳上げ、巻上げ格子付CMテント29などがある。
【0025】
本発明の伸縮部材としては、今までに述べたものと替えて、柱状のラックギヤー9に替えて四角パイプ30を用い、クラッチ12の爪片14を受け入れる孔31を多数個穿設したものでよい。上端には化粧キャップ32を固着する。
【0026】
【発明の効果】
本発明は、上述のように、面格子の上部を回動中心として回動する面格子を設けた跳上式面格子において、面格子内面中間部と面格子下方の下枠材との間に伸縮部材を設け、屋内側から面格子を開閉できるようにした跳上式面格子落下防止装置であるので、跳上式面格子を簡単な装置で、任意の開度に保持でき、ローコストで、安全で、しかも開閉の操作も簡単である。

[Prior art]
In a leap-type surface grid provided with a surface grid that rotates about the upper part of the surface grid, when the surface grid is pushed from the indoor side to the outdoor side, the surface grid is moved around the upper rotation axis. It turns outward and becomes eaves-like. If there is no one that holds this eaves-shaped surface grid, the surface grid is rotated by its own weight toward the indoor side and is dangerous.
[0003]
There are few jumping surface grids that maintain an eaves-like open state, but there are also systems that use strut bars to maintain the open state. Further, there is a device in which a damper is provided between the surface grid and the frame to prevent the surface grid from suddenly falling.
[0004]
[Problems to be solved by the invention]
In the case of a jumping surface grid, it is dangerous if there is nothing that keeps the open state of the eaves, and the strut rod cannot maintain the rotation angle of any surface grid, and it becomes expensive if a damper is provided .
