FIG. 1 is a configuration diagram of an elevator apparatus according to an embodiment of the present invention, and FIG. 2 is a plan view of a hoistway 1.
図において、かご２と釣合おもり３とはロープ１５を介して連結されており、このロープ１５が巻き掛けられた巻上機である駆動装置４を駆動することで、かご２と釣合おもり３とが昇降路１内を釣瓶式に昇降するよう構成されている。
In the figure, the car 2 and the counterweight 3 are connected via a rope 15, and the car 2 and the counterweight are driven by driving a driving device 4 that is a hoisting machine around which the rope 15 is wound. 3 is configured to move up and down in the hoistway 1 like a fishing bottle.
ここで、釣合おもり３はその両側方をガイドレール２２に案内されて昇降し、乗りかご２は同様にガイドレール２１に案内されて昇降するよう構成されている。
Here, the counterweight 3 is guided by the guide rails 22 on both sides thereof, and the car 2 is similarly guided by the guide rails 21 to be moved up and down.
また駆動装置４は、制御装置５により制御されている。
The driving device 4 is controlled by the control device 5.
また昇降路１内には昇降路内隔壁７が、昇降路１の頂部近傍から底部近傍まで延設されており、昇降路１内をかご２の昇降通路１ａと、釣合おもり３の昇降通路１ｂとに隔てて区画している。
A hoistway partition wall 7 extends in the hoistway 1 from the vicinity of the top of the hoistway 1 to the vicinity of the bottom. The hoistway 1 has a hoistway 1 a for the car 2 and an hoistway for the counterweight 3. It is divided into 1b.
図１に示すように、昇降路内隔壁７の昇降路１頂部近傍における設置高さは、かごの昇降路１内における最上部停止位置で、かご上保守作業を行う作業者の落下防止が図れるよう、かご天井２ａより高く設置され、且つ昇降路１の頂部近傍に配設した昇降路内機器であるロープ１５,駆動装置４などと干渉しない高さまで設置されるよう構成されている。
As shown in FIG. 1, the installation height in the vicinity of the top of the hoistway 1 of the hoistway partition 7 is the uppermost stop position in the hoistway 1 of the car, so that the worker who performs maintenance work on the car can be prevented from falling. Thus, it is configured to be installed higher than the car ceiling 2a and up to a height that does not interfere with the rope 15, the driving device 4 and the like, which are devices in the hoistway disposed near the top of the hoistway 1.

Furthermore, if the partition 7 in the hoistway is provided up to a height position of a car handrail 6 (indicated by a two-dot chain line in FIG. 1) installed on the car ceiling 2a in an elevator in which the partition 7 is not installed, Enough to prevent the person from falling.
言い換えれば、この昇降路内隔壁７を設ければ、かご天井２ａ上に設置されるかご上手摺り６は設けなくとも、作業者の落下防止効果を十分に図れる。
In other words, if this hoistway partition 7 is provided, the effect of preventing the operator from falling can be sufficiently achieved without providing the car handrail 6 installed on the car ceiling 2a.
さらに、昇降路内隔壁７により、かご２上での保守点検作業時の作業者の落下を回避できる構成としてかご上手摺り６を不要としたため、かご天井２ａと昇降路１の頂部との間隔寸法、ひいてはオーバーヘッド寸法を短縮可能であり、昇降路１全体の容積を低減したコンパクトなエレベーター装置とすることができる。
Further, the elevator inner partition wall 7 eliminates the need for the car handrail 6 so as to prevent the operator from falling during maintenance work on the car 2, and therefore, the distance between the car ceiling 2 a and the top of the hoistway 1. As a result, the overhead dimension can be shortened, and a compact elevator apparatus with a reduced volume of the entire hoistway 1 can be obtained.
また、昇降路内隔壁７の昇降路１底部近傍における設置高さは、かご２の昇降路１内における最下部停止位置で、かご２の側面の高さ位置まで設置され、且つ昇降路１の下部に配設した機器と干渉しない高さ位置まで設置されるよう構成されている。
