Description

【０００１】
【産業上の利用分野】
この発明は、引き戸を走行して開閉する出入口用サッシに関するものである。
【０００２】
【従来の技術】
家屋の出入口に取付ける玄関サッシや勝手口サッシ、或いは浴室の出入口に取付ける浴室サッシ（以下、これらを出入口用サッシと称する）として、サッシ枠に複数の障子嵌挿部を設け、各嵌挿部に障子を嵌挿する引違い式サッシと、サッシ枠の一方に障子格納部を設け、格納部より障子を出入れする片引き式サッシが知られているし、障子の代わりに引き戸を嵌挿したり、引き戸を吊下げ式に嵌挿するサッシも知られている。（例えば実開昭５４−１４８３４０号公報、実開昭５５−２２４９６号公報、実開昭６０−１９１６７４号公報）
【０００３】
【発明が解決しようとする課題】
障子を引違い式に嵌挿する出入口サッシにあっては、下枠材に障子走行用のレールを数条突出しているため、車椅子で出入する際、レールの間に車椅子の車輪が嵌まり込む問題点があった。
また障子を片引き式に嵌挿したり、引き戸を吊下げ式に嵌挿する出入口サッシにあっては、レール間に車椅子の車輪が嵌まり込むことはないが、内部と外部の間に段差があるため、車椅子で出入することが困難な問題点があった。
【０００４】
持手は引き戸の中間高さに取付けられ、しかも手指が挿入し得る程度に突出するのみであるため、車椅子から持手を把握することができないし、小児も持手を把握できない問題点があった。
そこでこの発明は、従来技術の有するこのような問題点に鑑みてなされたものであり、その目的とするところは、車椅子から簡単に引き戸が開閉できて、しかも車椅子による出入も容易な出入口用サッシを提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明の出入口用サッシは、サッシ枠の引き戸走行方向一方略半分に出入り区間を、他方に引き戸の格納区間を設け、サッシ上枠材に引き戸を走行自在に吊下げ、引き戸の走行にて出入区間を開閉する出入口用サッシであって、引き戸の下端部を嵌挿して案内する溝をサッシ下枠材の室内側に形成し、サッシ下枠材の出入区間に、前記溝の室外側を構成する下枠材レールより室外に向けて下降傾斜する踏板を脱着可能に嵌挿したことを特徴とする。さらに本発明は、出入り区間の室外側に内枠を、格納区間の室外側に遮蔽体を取付け、下枠材レールに排水口を、踏板の水切片に排水孔を設けること、引き戸の戸当框に枠幅より室内外に突出し、框枠の下部まで達する持手を取付けることを特徴とする。
【０００６】
【作用】
サッシ下枠材の出入区間に、下枠材レールより室外に向けて下降傾斜する踏板を嵌挿するものであるから、車椅子の出入に支障がない。また引き戸の戸当框に取付ける持手が、枠幅より室内外に突出し、しかも框枠の下部まで達するので、車椅子から引き戸を開閉走行し得る。

この遮蔽体７を格納区間Ｔに取付ける場合、予め図６（Ｂ）の如く下枠材１２の格納区間Ｔの延長壁２ｃと下段壁２ｂに補助体９を跨がって取付け、該補助体９と上枠材１１の下向溝１ａ、及び左縦枠材１３の内向片３ｂと方立１５の内向片５ｂを利用して遮蔽体７を取付けるものである。
【００１５】
本発明の出入口用サッシは上記構造であるから、従来通りにサッシ枠１と引き戸４を組立て、サッシ枠１の格納区間Ｔに遮蔽体７を取付け、出入区間Ｈに応じた大きさの内枠３を組立てておき、まずサッシ枠１を取付け、該サッシ枠１の出入区間Ｈに室外側より内枠３を挿入し、これを取付けると共に、格納区間Ｔに遮蔽体７を取付け、遮蔽体７の室外側まで外装Ｗを施す。
次にサッシ上枠材１１のレール２１に引き戸４を吊下げ、上枠材１１のレール２１及び下枠材１２の溝２０に沿って走行自在となした後、上枠材１１の室内側に内側壁１８を取付け、サッシ下枠材１２の出入区間Ｈに図９の如く踏板６を嵌合係止する。
【００１６】
サッシ枠１に雨水が吹込み、その一部がサッシ下枠材１２のレール２２より室内側に溜った場合、その雨水はレール２２の排水口２３より上段壁2aの室外側に流れ、上段壁2aに連続する延長壁2cより内枠３の下部材３２に流れ落ち、室外側に傾斜する下部材３２に沿って流れ、下部材３２の係合部2hに係止する踏板水切片6cの排水孔１６より外部に排水する。
サッシ下枠材１２の溝２０に異物が溜った場合、踏板６を取外し、異物を外部に掃き出す。
【００１７】
尚、本発明による出入口用サッシは上記実施例に限定されるものではなく、例えば格納区間Ｔの室外側に障子を嵌め殺しに取付けても同様の目的を達成する。また浴室の出入口に本発明サッシを取付ける場合、引き戸４の嵌挿側を脱衣場に向け、踏板６の傾斜側を浴室内に向けて取付ける。更にサッシ枠１と内枠３、及び引き戸４の組立て手順、並びに内枠３の取付けと、引き戸４の吊下げ手順は、本発明の要旨に反しない限り適宜変更可能である。
【００１８】
【発明の効果】
本発明による出入口用サッシは上記構造のとおりであるから、次に記載する効果を奏する。
サッシ下枠材の出入区間に、下枠材レールより室外に向けて下降傾斜する踏板を嵌挿するものであるから、車椅子の出入にも支障がない。また引き戸の戸当框に取付ける持手が枠幅より室内外に突出し、しかも框枠の下部まで達するので、車椅子から持手を把握して引き戸を簡単に開閉走行し得る。
【００１９】
下枠材レールに排水口を、踏板の水切片に排水孔を穿設しているので、サッシ枠に吹込む雨水が下枠材に溜ることがないし、出入区間に嵌挿する踏板を取外せば、下枠材に溜る異物を簡単に掃除し得る。しかも踏板は工具を用いずに着脱し得るので、その取扱いも簡便である。
本発明の出入口用サッシは、家屋の出入口に取付ける玄関サッシや勝手口サッシ、或いは浴室の出入口に取付ける浴室サッシとして最適である。
