Description

【０００１】
【発明の属する技術分野】
この発明は、主としてエレベーターの乗場に設けられて、表面が出入口の上縁部正面と同一面に配置されて動作し出入口を開閉するエレベーター用引き戸に関する。
【０００２】
【従来の技術】
従来のエレベーター用引き戸においては、上縁部が吊り手によって吊持される引き戸の要部を形成した表板が設けられ、表板の両側縁部がそれぞれ裏面方向に屈折された屈折面及びこの屈折面の自由端側がそれぞれ屈折されて表板の裏面と対向する対向部が表板に形成される。そして、横断面溝形をなす上部補強材が、それの溝形底面の外面を表板の裏面に接して配置されて、長手が水平方向に配置されて表板の上縁部に配置され、すみ肉溶接及びスポット溶接によって表板に固定される。
【０００３】
また、仕切板が上部補強材の上面に上方に突出して設けられて表板の対向部寄りに配置され、取付ねじによって上部補強材に締結される。そして、横断面溝形をなす縦補強材が溝形の開口部側に設けられたフランジ部を介して表板の裏面に接して配置され、スポット溶接によって表板に固定されて長手が上下方向に配置され表板の幅方向の中間に配置される。また、上部補強材の溝形内に形成された取付台に取付金具が締結されて、この取付金具に前述の吊り手を締結機構を介して装着するように構成されている。
【０００４】
上記のように構成された従来のエレベーター用引き戸は、上部補強材の取付台を介して引き戸の裏面に吊り手の下部が締結されて上方に突出して配置される。そして、このような構成の引き戸の上端面が出入口の上縁部材、すなわち三方枠の幕板の下面と空隙を形成して対面して配置されて、引き戸の表面が出入口の上縁部正面と同一面に配置される。このような構成によって、出入口に引き戸が装備されて開閉動作し出入口を開閉するようになっている。（例えば、特許文献１参照）。

【発明が解決しようとする課題】
従来のエレベーター用引き戸では、引き戸の裏面に上部補強材を介して締結された吊り手によって引き戸が吊持される。このため、上部補強材が溶接手段によって表板に強固に固定されて吊り手を介して作用する吊持反力が支持される。しかし、上部補強材の溶接作業によって表板に反り、捻りなどの溶接歪みが発生する。この溶接歪みの修正のため多くの作業時間を要し、またスポット溶接痕が生じるため、表板が塗装仕上げの場合には塗装下地の塗膜を厚くする必要があって、塗装仕上げの費用が増大するという問題点があった。
【０００７】
また、表板がステンレス鋼板の鏡面仕上げのときにはスポット溶接痕の修正が出来ず、引き戸の鏡面仕上げの仕様には対応不能であった。さらに、吊り手が上部補強材に締結されるため上部補強材自体の溶接歪みによって、吊り手を所定の位置に締結するために煩雑な位置調整作業が必要となってエレベーターの据付費が嵩むという問題点があった。
【０００８】
この発明は、かかる問題点を解消するためになされたものであり、上縁部に設けられる補強構造体を、製作工程における加工作業に起因する変形を伴うことなく表板に強固に固定することができるエレベーター用引き戸を得ることを目的とする。
【０００９】
【課題を解決するための手段】
この発明に係るエレベーター用引き戸は、上縁部が吊り手によって吊持される引き戸の要部を形成する表板と、この表板の両側縁部がそれぞれ裏面方向に屈折された屈折面及びこの屈折面の自由端側がそれぞれ屈折されて表板の裏面と対向する対向部と、横断面溝形をなし溝形の開口部側が表板の裏面に接着手段によって装着され長手が上下方向に配置されて表板の幅方向の中間に配置され、かつ溝形の底面側が表板の対向部面に対応した位置に配置された縦補強材と、横断面溝形の溝底外面に接着部が形成されてこの接着部が表板の裏面に接着手段によって装着され、長手が水平方向に配置されて溝形における上側の側壁上面が表板の上端よりも下方に配置され、溝形における下側の側壁の自由端側が下方に屈折されてなる取付部が表板の対向部面及び縦補強材における溝底外面に重合して配置された上部補強材と、この上部補強材の上面に締結されて上方に突出し表板の対向部寄りに配置された仕切板と、表板の対向部及び縦補強材と取付部との重合部に配置されて重合部において互いに対面した部材相互を締結したリベットとを備え、上記上部補強材を、表板の上端に達する接着部が形成され、またこの接着部の上縁部における要部が切り曲げされて横断面溝形に形成され、この溝形の側壁が水平に配置されてなる締結面が設けられたものとし、締結面に仕切板を締結したものである。
また、この発明に係るエレベーター用引き戸は、上縁部が吊り手によって吊持される引き戸の要部を形成する表板と、この表板の両側縁部がそれぞれ裏面方向に屈折された屈折面及びこの屈折面の自由端側がそれぞれ屈折されて表板の裏面と対向する対向部と、横断面溝形をなし溝形の開口部側が表板の裏面に接着手段によって装着され長手が上下方向に配置されて表板の幅方向の中間に配置され、かつ溝形の底面側が表板の対向部面に対応した位置に配置された縦補強材と、横断面溝形の溝底外面に接着部が形成されてこの接着部が表板の裏面に接着手段によって装着され、長手が水平方向に配置されて溝形における上側の側壁上面が表板の上端よりも下方に配置され、溝形における下側の側壁の自由端側が下方に屈折されてなる取付部が表板の対向部面及び縦補強材における溝底外面に重合して配置された上部補強材と、この上部補強材の上面に締結されて上方に突出し表板の対向部寄りに配置された仕切板と、表板の対向部及び縦補強材と取付部との重合部に配置されて重合部において互いに対面した部材相互を締結したリベットとを備え、上記仕切板が、横断面溝形をなし溝形底辺が上部補強材の上面に重合されて締結され、溝形の一方の側壁が表板の上縁部裏面に接して配置されたものである。

【発明の実施の形態】
実施の形態１．
図１〜図３は、この発明の実施の形態の一例を示す図で、図１はエレベーターの出入口における上縁部箇所の縦断側面図、図２は図１の引き戸の縦断面図、図３は図１の引き戸の裏面側の斜視図である。図において、出入口１の上縁部材２の下端面３に対して詳細は後述するが引き戸４の上端面５が空隙を形成して配置される。そして、上縁部材２正面と引き戸４の表面が同一面に配置される。
【００１１】
また、出入口１の上縁部にハンガーケース６が配置されて出入口１が設けられた壁に固定され、ハンガーケース６に戸のレール７が設けられて長手が水平に配置される。そして、戸のレール７に案内されて転動するローラを有する吊り手８が設けられて下端の締結部９が引き戸４の上端よりも下方に配置される。
【００１２】
また、引き戸４の裏面に取付金具１０の一側が締結されて、吊り手８の締結部９に対向した他側がボルト及びナットからなる締結具１１によって吊り手８に締結される。そして、引き戸４が次ぎに述べるように構成される。すなわち、表板１２の両側縁部がそれぞれ裏面方向に屈折された屈折面１３及びこの屈折面１３の自由端側がそれぞれ屈折されて表板１２の裏面と対向する対向部１４が形成される。
【００１３】
そして、上部補強材１５の横断面溝形における溝底外面に接着部１６が形成されて、接着部１６が表板１２の裏面に接着剤、両面接着テープ等の接着手段１７によって装着され、長手が水平方向に配置されて上部補強材１５の溝形上面が表板１２の上端よりも下方に配置され、上部補強材１５の溝形における下側の側壁の自由端側が下方に屈折されてなる取付部１８が表板１２の対向部１４の内面に重合して配置される。
【００１４】
また、横断面Ｌ字形の仕切板１９が上部補強材１５の溝形上面に配置されてＬ字の一辺が上部補強材１５の溝形上面に重合されてなべねじ２０によって上部補強材１５に締結され、Ｌ字の他辺は上面に上方に突出して上縁部材２の下端面３の裏面側に空隙を形成して配置される。
【００１５】
また、横断面溝形をなす縦補強材２１が溝形の開口部側に形成されたフランジ状部を介して表板１２の裏面に接着剤、両面接着テープ等の前述の接着手段１７によって装着され、長手が上下方向に配置されて表板１２の幅方向の中間に配置される。そして、縦補強材２１の上端が上部補強材１５の溝形の下面に接近して配置され、溝形の底面側２２外面が上部補強材１５の取付部１８の表板１２裏面との対向面に重合して配置される。
【００１６】
そして、表板１２の対向部１４及び縦補強材２１と上部補強材１５の取付部１８との重合部において、互いに対面した部材相互がリベット２３によって締結される。なお、吊り手８の締結部９が締結される前述の取付金具１０は、上部補強材１５の取付部１８と縦補強材２１との重合部に締結される。
【００１７】
上記のように構成されたエレベーター用引き戸において、引き戸４の上端面５が出入口１の上縁部材２の下端面３と空隙を形成して対面して配置されて、引き戸４の表面が上縁部材２の正面と同一面に配置される。そして、このように配置された引き戸４が動作して出入口１を開閉する。また、引き戸４の表板１２に上部補強材１５の接着部１６及び縦補強材２１の溝形開口部側が接着手段１７によって装着される。
【００１８】
また、上部補強材１５の取付部１８が表板１２の対向部１４内面及び縦補強材２１の溝形底面側２２の外面に重合して配置されて、表板１２の対向部１４等と上部補強材１５の取付部１８との重合部が、重合箇所において互いに対面した部材相互がリベット２３によって締結される。これにより、表板１２に対して上部補強材１５及び上部補強材１５の取付部１８が強固に装着され、上部補強材１５箇所において高い剛性を得ることができる。
【００１９】
この構成によって、上部補強材１５の取付部１８に締結された取付金具１０を介して吊り手８が装着されて、吊り手８を介して作用する引き戸４の吊持荷重が上部補強材１５、縦補強材２１、リベット２３に分散して表板１２に伝達される。このため、高剛性を有する引き戸４を吊り手８によって吊持することよって、円滑に開閉動作させることができる。
【００２０】
また、表板１２、上部補強材１５及び縦補強材２１が溶接されることなく結合される。したがって、表板１２に溶接歪み、スポット溶接痕が生じることがなく、溶接歪み等の修正のための煩雑な手数を省くことができる。また、スポット溶接痕が生じないので、表板１２の塗装仕上げの仕様に対して塗装下地工程を簡略化することができて、表板１２の仕上げの費用を低減することができる。
【００２１】
さらに、スポット溶接痕が生じないので表板１２のステンレス鋼板の鏡面仕上げの仕様に容易に対応することができる。また、引き戸４の溶接歪みが減少することによって、吊り手８を簡易な位置調整作業により引き戸４の所定の位置に容易に締結することができエレベーターの据付費を節減することができる。
【００２２】
実施の形態２．
図４及び図５は、この発明の他の実施の形態の一例を示す図で、図４は前述の図２相当図、図５は図４の引き戸の裏面側の斜視図である。なお、図４及び図５の他は前述の図１〜図３と同様にエレベーター用引き戸が構成されている。図において、図１〜図３と同符号は相当部分を示し、上部補強材２４に表板１２の上端に達する接着部２５が形成される。また、接着部２５の上縁部における要部が切り曲げされて横断面において溝形に形成され、上面に水平に配置された締結面２６が設けられて上部補強材２４の長手の両端部寄りにそれぞれ配置される。
【００２３】
上記のように構成されたエレベーター用引き戸において、上部補強材２４の締結面２６に仕切板１９が配置されてべねじ２０によって上部補強材２４に締結される。そして、上部補強材２４の取付部１８に締結された取付金具１０を介して吊り手８が装着されて、吊り手８を介して作用する引き戸４の吊持荷重が上部補強材２４、縦補強材２１、リベット２３に分散して表板１２に伝達される。
【００２４】
また、表板１２、上部補強材２４及び縦補強材２１が溶接されることなく結合される。したがって、詳細な説明を省略するが図４及び図５の実施の形態においても図１〜図３の実施の形態と同様な作用が得られる。さらに、表板１２の上縁部において上部補強材２４の接着部２５による接着面積が増加し、表板１２の上縁部の強度が向上する。これによって、引き戸４の運搬時、据付作業時等における変形の発生を未然に防止することができる。
【００２５】
実施の形態３．
図６も、この発明の他の実施の形態の一例を示す前述の図２相当図である。なお、図６の他は前述の図１〜図３と同様にエレベーター用引き戸が構成されている。図において、図１〜図３と同符号は相当部分を示し、横断面溝形の仕切板２７が、上部補強材１５に形成された横断面溝形の上面に配置され、仕切板２７の溝形の底辺が接着部１６の溝形上面に重合されて、なべねじ２０によって上部補強材１５に締結される。
【００２６】
そして、仕切板２７の溝形における表板１２の対向部１４側の側壁は上方に突出して上縁部材２の下端面３の裏面側に空隙を形成して配置される。また、仕切板２７の溝形における表板１２の反対向部１４側の側壁は表板１２の裏面に接して配置される。
【００２７】
上記のように構成されたエレベーター用引き戸においても、上部補強材１５の接着部１６における溝形上面に仕切板２７に締結される。そして、上部補強材１５の取付部１８に締結された取付金具１０を介して吊り手８が装着されて、吊り手８を介して作用する引き戸４の吊持荷重が上部補強材１５、縦補強材２１、リベット２３に分散して表板１２に伝達される。
【００２８】
また、表板１２、上部補強材１５及び縦補強材２１が溶接されることなく結合される。したがって、詳細な説明を省略するが図６の実施の形態においても図１〜図３の実施の形態と同様な作用が得られる。さらに、表板１２の上縁部裏面ににおいて仕切板２７の側壁が接して配置される。これによって、表板１２の上縁部の強度が増し、引き戸４の運搬時、据付作業時等における変形の発生を未然に防止することができる。
【００２９】
【発明の効果】
本願における第１の発明は以上説明したように、上縁部が吊り手によって吊持される引き戸の要部を形成する表板と、この表板の両側縁部がそれぞれ裏面方向に屈折された屈折面及びこの屈折面の自由端側がそれぞれ屈折されて表板の裏面と対向する対向部と、横断面溝形をなし溝形の開口部側が表板の裏面に接着手段によって装着され長手が上下方向に配置されて表板の幅方向の中間に配置され、かつ溝形の底面側が表板の対向部面に対応した位置に配置された縦補強材と、横断面溝形の溝底外面に接着部が形成されてこの接着部が表板の裏面に接着手段によって装着され、長手が水平方向に配置されて溝形における上側の側壁上面が表板の上端よりも下方に配置され、溝形における下側の側壁の自由端側が下方に屈折されてなる取付部が表板の対向部面及び縦補強材における溝底外面に重合して配置された上部補強材と、この上部補強材の上面に締結されて上方に突出し表板の対向部寄りに配置された仕切板と、表板の対向部及び縦補強材と取付部との重合部に配置されて、重合部において互いに対面した部材相互を締結したリベットとを備え、上記上部補強材を、表板の上端に達する接着部が形成され、またこの接着部の上縁部における要部が切り曲げされて横断面溝形に形成され、この溝形の側壁が水平に配置されてなる締結面が設けられたものとし、締結面に仕切板を締結したものである。
また、第２の発明に係るエレベーター用引き戸は、上縁部が吊り手によって吊持される引き戸の要部を形成する表板と、この表板の両側縁部がそれぞれ裏面方向に屈折された屈折面及びこの屈折面の自由端側がそれぞれ屈折されて表板の裏面と対向する対向部と、横断面溝形をなし溝形の開口部側が表板の裏面に接着手段によって装着され長手が上下方向に配置されて表板の幅方向の中間に配置され、かつ溝形の底面側が表板の対向部面に対応した位置に配置された縦補強材と、横断面溝形の溝底外面に接着部が形成されてこの接着部が表板の裏面に接着手段によって装着され、長手が水平方向に配置されて溝形における上側の側壁上面が表板の上端よりも下方に配置され、溝形における下側の側壁の自由端側が下方に屈折されてなる取付部が表板の対向部面及び縦補強材における溝底外面に重合して配置された上部補強材と、この上部補強材の上面に締結されて上方に突出し表板の対向部寄りに配置された仕切板と、表板の対向部及び縦補強材と取付部との重合部に配置されて重合部において互いに対面した部材相互を締結したリベットとを備え、上記仕切板が、横断面溝形をなし溝形底辺が上部補強材の上面に重合されて締結され、溝形の一方の側壁が表板の上縁部裏面に接して配置されたものである。
【００３０】
これによって、引き戸の表板に上部補強材の接着部及び縦補強材の溝形開口側が接着手段によって装着される。また、上部補強材の取付部が表板の対向部及び縦補強材における溝底外面に重合して配置されて、表板の対向部等と上部補強材の取付部との重合部が、重合箇所において互いに対面した部材相互をリベットによって締結する。これにより、表板に対して上部補強材が強固に装着されて上部補強材箇所において高い剛性を得ることができる。この構成によって、上部補強材の取付部を介して吊り手が締結されて、吊り手によって引き戸に作用する引き戸の吊持荷重が、上部補強材、縦補強材、リベットに分散して表板に伝達される。このため、高剛性を有する引き戸を吊り手によって吊持して円滑に開閉動作させることができる。そして、表板、上部補強材及び縦補強材が溶接されることなく結合されるので、表板に溶接歪み、スポット溶接痕が生じることがなく、溶接歪み等の修正のための煩雑な手数を省くことができる。また、スポット溶接痕が生じないので表板の表面仕上げ工程を簡略化できる。したがって、仕上げの費用を低減する効果がある。また、引き戸の溶接歪みが減少することによって吊り手を簡易な位置調整作業により引き戸の所定の位置に容易に配置することができてエレベーターの据付費を節減する効果がある。
更に、上記第１の発明によれば、表板の上縁部において上部補強材の接着部による接着面積が増加し、表板の上縁部の強度が向上する。これによって、引き戸の運搬時、据付作業時等における変形の発生を未然に防止することができる。
また、上記第２の発明によれば、表板の上縁部裏面において仕切板の側壁が接して配置されるため、表板の上縁部の強度が増し、引き戸の運搬時、据付作業時等における変形の発生を未然に防止することができる。
