【発明の属する技術分野】
本発明は、エレベータかご室の手摺構造に関する。
【0002】
【従来の技術】
従来のエレベータのかご室を図を参照して説明する。
図7に示すように、従来のエレベータのかご室は入口部を除く周囲を側板5で囲って構成されている。この入口部はその両側に入口柱4を設けており、この入口柱4には両端を折り曲げた鋼板が締結されている。また、かご室の側板5は鋼板の両端を折り曲げ、その折り返しを利用して隣接する側板5同士を締結する構造になっている。エレベータのかご室内の手摺は、図8に示すように手摺本体1にブラッケット2を溶接3によって固定し、このブラッケット2を側板5にボルト・ナット16で取付、固定している。
【0003】
【発明が解決しようとする課題】
ところで、エレベータのかご室を構成する側板5は、板金部品であるため幅方向の許容寸法誤差は通常±1mmの範囲であり、側板5の分割数が増えるとその累積誤差が大きくなってしまうという可能性がある。また、側板の寸法をいくら精度良く作ろうとしても、板金部品を用いているため限界があり、さらに、組立誤差も考慮する必要があるので、累積誤差はさらに大きくなる可能性がある。
【0004】
また、エレベータ据付時に側板の裏面に作業者が入れないことがあるため、図8のように側板5の裏面に手摺本体1を側板5に取り付けるためのナットを予め取り付けておく必要があった。
【0005】
一方、側板5に加工された手摺取付部の位置寸法にも誤差が生じることがあり、手摺本体1をいくら精度良く製作しても側板5への手摺本体1の取り付けが困難であったり、場合によっては取り付けられない可能性があった。特に、かご室内の側板5に両側面と背面の三方一体で取付ける手摺は、その誤差により取付けが困難になる可能性が大きかった。
【0006】
本発明は上記状況に対処するためになされたもので、本発明の目的は、エレベータかご室の側板に出来上がり寸法の誤差が生じても、エレベータかご室の側板に容易に手摺を取付けることができるエレベータかご室の手摺構造を提供することにある。
【0007】
本発明の他の目的は、エレベータかご室の側板の出来上がり寸法や、かご室組立誤差による寸法等に誤差があっても問題なく手摺を取付けることができるエレベータかご室の手摺取付方法を提供することにある。
【0008】
【課題を解決するための手段】
上記目的を達成するため、請求項1記載の発明は、複数に分割された側板で構成されたエレベータかご室と、前記側板に取付ける複数の手摺取付用のブラケットと、前記ブラケットを断面円形状でかつ平面部を設けた手摺本体に結合するために当該ブラケットに形成されたフランジと、前記手摺本体内部に挿入され手摺長手方向にスライド可能でかつ断面形状に平面部を設けたコマと、前記フランジと前記コマを締結する締結手段と、前記ブラケットが前記コマのスライドにより手摺長手方向に可動できるように前記手摺本体の下部の周面にあけられた長穴とを備え、前記コマの平面部と前記手摺本体の平面部が接するように配置したことを特徴とする。
【0009】
請求項1によると、エレベータかご室の側板への取付けブラケットが手摺長手方向に摺動可動とすることで、ブラケット間の寸法調整ができるので、側板の出来上がり寸法誤差による側板の手摺取付け部間の寸法誤差が発生しても容易に手摺をかご室側板の適正位置に取付けることができる。また、手摺本体の断面形状に平面部を設け、この平面部に手摺本体内部をスライドするコマの平面部を接するように配置することで、コマの回転を抑制できる。
【0012】
請求項記載の発明は、請求項1記載のエレベータかご室の手摺構造において、手摺本体内部をスライドするコマの断面形状を多角形の構成としたことを特徴とする。
【0013】
請求項記載の発明によると、手摺本体内部をスライドするコマの断面形状を多角形にしたので、手摺本体内面との接触面積を減らすことができコマのスライドがスムーズになる。
【0014】
請求項記載の発明は、請求項1記載のエレベータかご室の手摺構造において、手摺本体に手摺長手方向に沿った長穴をあけると共に、手摺本体内部をスライドするコマにねじ穴をあけ、さらに前記コマのねじ穴と前記手摺本体の穴にビスを取付け、前記コマと前記手摺本体をねじ止め固定する構成としたことを特徴とする。
【0015】
請求項記載の発明によると、手摺本体にあけた穴と手摺本体内部をスライドするコマにあけたねじ穴にビスを取付け締め込むことにより、手摺をエレベータかご室内に取付けた後のグラツキを抑制できる。
【0016】
請求項記載の発明は、請求項1記載のエレベータかご室の手摺構造において、手摺本体にあけられた手摺長手方向の長穴の横にピン穴をあけ、このピン穴にピンを打ち込み、このピンにより前記コマの動きを制限する構成としたことを特徴とする。
【0017】
請求項記載の発明によると、手摺本体のブラケット可動用の長穴の横に穴をあけ、ピンを打ち込んでおくことにより、コマを手摺本体に入れた際、コマが長穴付近で止まるため、コマの位置を直す作業がなくなる。
【0018】
請求項5記載の発明は、請求項1記載のエレベータかご室の手摺構造において、ブラケットの側板に取付けるフランジを手摺長手方向に直行する方向にスライド可能な構成としたことを特徴とする。
【0019】
請求項記載の発明によると、手摺長手方向にスライドするブラケットが手摺の横方向にもスライドすることにより、エレベータかご室の側板の出来上がり寸法や、かご室組立誤差による平面方向の寸法誤差に対して手摺を適正位置に取付けることができる。
【0020】
【発明の実施の形態】
以下、本発明の実施の形態を図を参照して説明する。
図1は本発明の第1実施形態のエレベータかご室の手摺構造の構成図であり、同図(a)は側面図、同図(b)は同図(a)をA方向からみた正面図、同図(c)は同図(a)をB方向からみた下面図である。
【0021】
図に示すように、本実施形態の手摺は、手摺本体1aを、L字形に形成されたブラケット2aのフランジ18を介して側板5にボルト・ナット16により締結することにより側板5に取付けられる。手摺本体1aは円筒状をなし、その内部に手摺長手方向にスライド可能なコマ6が挿入されており、また下側の周面に手摺長手方向に沿って延びる長穴9が形成されている。ブラケット2aの手摺本体1a側の端部にはフランジ7が形成されており、このフランジ7をビス8によりコマ6に締結することにより、ブラケット2aと手摺本体1aが連結され、しかも手摺本体1aの手摺長手方向にあけられた長穴9に沿って移動できるようになっている。
【0022】
本実施形態は、上記のように構成されているので、コマ6が手摺本体1a内をスライドでき、このコマ6に締結されたブラケット2aが手摺長手方向に移動できることによって、ブラケット2aの取付位置調整が容易にできる。
【0023】
したがって、エレベータのかご室を構成する側板5の出来上がり寸法に誤差があり、側板5の手摺ブラケット取付け部間に寸法誤差が生じた場合でも容易に手摺を側板5の適正位置に取付けることができる。また、ブラケット2aは長穴9によって手摺本体1aの周方向への移動が制限されているので、手摺取付時にコマ6の回転による手摺本体1aのぐらつきがなく、ブラケット2aを側板5に取付ける作業効率が向上する。
【0024】
図2は本発明の第2実施形態のエレベータかご室の手摺構造の側面図である。
図に示すように、本実施形態の手摺は、手摺本体1bの円形断面形状の下部に平面部10を形成し、この平面部10に長穴9を形成している。また、この手摺本体1bの内部にスライド可能に挿入されたコマ6の下部にも平面部10aを形成し、コマ6はこの平面部10aを介して手摺本体1bの平面部10上をスライドする一方、周方向の回転ができないようにしたものである。
【0025】
本実施形態は、上記のように構成されているので、コマ6は手摺本体1bの手摺長手方向にあけられた長穴9内を摺動し、ブラケット2aを側板5の適正位置にかつコマ6が手摺本体1b内部で周方向に回転しないように取付けることができ、またコマ6の回転による手摺本体1bのぐらつきもなくなり、かつコマ6の向きを直す作業をする必要がなくなる。
【0026】
図3は本発明の第3実施形態のエレベータかご室の手摺構造の側面図である。
本実施形態は図2の第2実施形態に対して、手摺本体1b内部をスライドするコマ6aの断面形状を多角形とし、この多角形の一辺を手摺本体1bの円形断面形状の下部の平面部10に載置した点に相違があり、その他の構成は同一であるので、同一部分には同一符号を付して説明を省略する。
【0027】
本実施形態は、上記のようにコマ6aの断面形状を多角形に形成し、そのうちの1つの平面部を手摺本体1bの平面部10上に位置させるので、コマ6aが手摺本体1b内部で回転しないようにかつスライド可能な状態に維持して手摺本体1bの側板5に取付けることができ、しかもコマ6aと手摺本体1b内面との接触面積を減らすことでコマ6aの摺動抵抗が減り、コマ6aの動きがスムーズになる。
【0028】
図4は本発明の第4実施形態のエレベータかご室の手摺構造の構成図であり、同図(a)は正面図、同図(b)は同図(a)のA方向からみた下面図である。
本実施形態は図1の第1実施形態に対して、手摺本体1a内部をスライド可能なコマ6bにねじ穴(図示しない)をあけ、また、手摺本体1aに形成されている長穴9に隣接してさらに長穴11をあけ、この長穴11を介してコマ6bのねじ穴にビス12を取付け締め込むことにより、コマ6bと手摺本体1bを固定するようにした点に相違があり、その他の構成は同一であるので、同一部分には同一符号を付して説明を省略する。
【0029】
本実施形態は、上記のようにビス12によるコマ6bと手摺本体1bの固定を付加したことで、エレベータかご室の側板5に手摺を取付けた後の手摺本体1aのグラツキをなくすことができる。
【0030】
図5は本発明の第5実施形態のエレベータかご室の手摺構造の構成図であり、同図(a)は正面図、同図(b)は同図(a)のA方向からみた下面図である。
本実施形態は、図1の第1実施形態に対して、手摺本体1aの長穴9に隣接してピン穴を(図示しない)あけ、このピン穴にピン13を打ち込んでいる点が相違し、その他の構成は同一であるので、同一部分には同一符号を付して説明を省略する。
【0031】
本実施形態は、上記のように手摺本体1bの長穴に隣接して設けられたピン穴にピン13を打ち込んでいるので、手摺製造時、コマ6を手摺本体1a内部に挿入した際、コマ6がピン13に当たり手摺本体1aの長穴9の位置で止まって位置決めされるため、ブラケット2aに形成したフランジ7をコマ6にビス8で締結する際、コマ6の位置を長穴9の位置に調整する作業がなくなる。
【0032】
図6は本発明の第6実施形態のエレベータかご室内の手摺構造の構成図であり、同図(a)は側面図、同図(b)は同図(a)をA方向からみた正面図、同図(c)は同図(a)をB方向からみた下面図である。
【0033】
本実施形態は図2の第2実施形態に対して、手摺本体1aの長穴9の横にピン穴(図示しない)をあけ、このピン穴にピン13を打ち込んである点と、ブラケット2bが側板5に取付けるためのフランジ14とブラケット2bを分割し、フランジ14の穴にブラケット2bの軸17を差し込み、ビス15により固定した点と、手摺本体1aに形成されている長穴9に隣接して長穴11をあけ、この長穴11に差し込んだビス12によりコマ6と手摺本体1aを固定した点に相違があり、その他の構成は同一であるので、同一部分には同一符号を付して説明を省略する。
【0034】
本実施形態は、上記のようにフランジ14とブラケット2bとを着脱自在に構成したので、側板5に取付けるフランジ14を軸17に沿って手摺長手方向に直交する方向にスライドさせて、ビス15により固定できる。このように、側板5に取付けるフランジ14が手摺長手方向に直行する方向にスライドすることで手摺本体1b全体が手摺長手方向に直行する方向にもスライドするので、側板5の出来上がり寸法誤差や、かご室の平面寸法の組立誤差が発生した場合でも、手摺をかご室側板5の適正位置に容易に取付けることができる。
【0035】
【発明の効果】
以上説明したように、本発明によれば、エレベータかご室を構成する側板の出来上がり寸法誤差や、かご室の平面方向での組立寸法誤差が発生した場合でも、手摺本体に取付けられるブラケットが手摺長手方向にスライドして位置調整できるので、手摺を側板の適正位置に容易に取り付けることができる。
