【発明が解決しようとする課題】
従来のエレベーター装置では、二つの昇降路が互いに隣接して設けられる場合であって、一方の昇降路の上端が他方の昇降路の上端よりも上方に配置されるときに、エレベーターを設置する建物の高さが前述の一方の昇降路の上方における機械室高さに対応した高さになる。このため、建物の高さが無闇に高くなり建物における日照権に基づく高さ制限による制約を受け易くなる。また、二つの昇降路のそれぞれに別個に機械室を設けることになって建築費が嵩み、またそれぞれの機械室においてエレベーターの保守作業を行うことになり煩雑な手数が掛かるという問題点があった。
【0006】
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、互いに隣接した昇降路の一方の上端を他方の昇降路上端よりも上方に配置した構成であって、上記一方の昇降路上端における上方構造体の高さが低いエレベーター装置を得ることを目的とする。
【0007】
【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装置においては、第一の昇降路、この第一の昇降路の上端の上側及びこの上側を水平方向に延長した場所に形成された機械室並びにこの機械室に設置されて第一の昇降路の上方に配置された第一の巻上機と、第一の昇降路に隣接して設けられて上端が第一の昇降路の上端よりも上方に配置された第二の昇降路と、機械室に設置された第二の巻上機と、第二の昇降路の上端の上側及び第二の巻上機の上方に配置された支持梁と、この支持梁に枢着されて第二の昇降路の上方に配置された昇降路側滑車及び第二の巻上機の上方に配置された巻上機側滑車と、第二の昇降路を昇降する昇降体を吊持し昇降路側滑車及び巻上機側滑車に巻掛けられて第二の巻上機の駆動綱車に巻掛けられた主索とが設けられる。
【0008】
【発明の実施の形態】
実施の形態1.
図1は、この発明の実施の形態の一例を示す図で、昇降路上部の縦断面図である。図において、第一の昇降路1の上端の上側及びこの上側から水平方向に延長した場所に形成された機械室2が設けられ、また機械室2に機械台3を介して第一の巻上機4が設置されて第一の昇降路1の上方に配置される。そして、第一の巻上機4の駆動綱車5に第一の主索6が巻掛けられて、一端によりかご7がまた他端によってつり合おもり8が吊持される。
【0009】
また、第二の昇降路9が第一の昇降路1に隣接して設けられて上端が第一の昇降路1の上端よりも上方に配置され、また機械室2に機械台10を介して第二の巻上機11が設置されて第一の巻上機4の反第二の昇降路9側に配置される。そして、支持梁12が第二の昇降路9の上端の上側から第一の巻上機4の上方を経て第二の巻上機11の上方に設けられる。

【0015】
【発明の効果】
この発明は以上説明したように、第一の昇降路、この第一の昇降路の上端の上側及びこの上側を水平方向に延長した場所を形成された機械室並びにこの機械室に設置されて第一の昇降路の上方に配置された第一の巻上機と、第一の昇降路に隣接して設けられて上端が第一の昇降路の上端よりも上方に配置された第二の昇降路と、機械室に設置された第二の巻上機と、第二の昇降路の上端の上側及び第二の巻上機の上方に配置された支持梁と、この支持梁に枢着されて第二の昇降路の上方に配置された昇降路側滑車及び第二の巻上機の上方に配置された巻上機側滑車と、第二の昇降路を昇降する昇降体を吊持し昇降路側滑車及び巻上機側滑車に巻掛けられて第二の巻上機の駆動綱車に巻掛けられた主索とを設けたものである。
【0016】
このような構成において、第一の昇降路の上端の上側に対応した高さに設けられた機械室に第一の巻上機及び第二の巻上機が設置される。また、機械室の高さを、第二の昇降路の上端の上側に対して支持梁並びに昇降路側滑車の設置のための所要高さを加えた寸法とすることができる。このため、第二の昇降路の上端の上側に第二の昇降路のみに対応した別個の機械室を設けるときの高さよりも低くすることができる。したがって、エレベーター装置を設置する建物の高さが無闇に高くなることがなく、建物における日照権に基づく高さ制限回避を容易化する効果がある。また、一つの機械室に第一の巻上機及び第二の巻上機が設置されるので、建築費を節減する効果がある。さらに、第一の巻上機及び第二の巻上機並びにそれぞれの巻上機によって運転されるエレベーターの保守、点検、調整等の作業を機械室において行うことができるので、これらの作業能率を向上し、また作業が容易にでき作業費を低減する効果がある。
