Description

【0001】
【発明の属する技術分野】
本発明は、エレベーター装置に係り、特に、火災時に昇降路と乗場との間で火または煙の流通を防ぐ手段を備えたエレベーター用防火装置に関する。
【0002】
【従来の技術】
従来から、火災時に昇降路と乗場との間を塞ぐ防火防煙シャッターを備えたエレベーター装置が提案されている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開2001―276243号公報(第6図)
【0004】
【発明が解決しようとする課題】
しかしながら、上述した特許文献1のエレベーター装置では、火災発生時、防火防煙シャッターは一斉に駆動されるようになっていた。このため、火災発生時に乗りかご内に利用客がいた場合、乗りかごが所定階に非常停止しても、防火シャッターが既に閉じられており、利用客が乗りかごから出られないという重大事故の生じる恐れがあった。
【0005】
したがって、本発明の目的は、火災発生時等に乗りかご内にいた利用客が安全に避難することのできるエレベーター装置を提供することにある。
【0006】
【課題を解決するための手段】
上述の目的を達成するために、本発明では、複数階床からなる建屋に設けられた昇降路と乗場との間で火または煙が流通するのを防ぐ防火防煙手段と、該防火防煙手段を開閉させる駆動装置を備えたエレベーター装置において、前記建屋に設けられた非常電源装置と、火災発生時に乗りかごを休止させる乗りかご制御手段と、前記乗りかご内に利用客がいないことを確認する手段と、該手段により利用客がいないことが確認され次第前記駆動装置へ閉じ指令を出す駆動装置制御手段を有し、停電時に前記非常電源装置で各階の前記駆動装置毎に1台ずつ駆動し、最終的に全ての階の防火防煙手段を閉じることを特徴とする。
【0007】
上述した構成によれば、火災発生時、乗りかごに対して休止指令が出され、乗りかごが所定階に休止したことを確認した後に、防火防煙手段を閉じるため、火災発生時に乗りかご内にいた利用客が、乗りかご内に閉じ込められるという事態の発生を防止することができる。
【0008】
【発明の実施の形態】
以下、本発明のエレベーター装置の実施の形態を図に基づいて説明する。
【0009】
図1は本発明の一実施形態におけるエレベーター装置を備えた建屋全体の縦断側面図、図2は本発明の動作例を示すフローチャートである。
【0010】
図1において、5階床からなる建屋1の側方には、エレベーター用の昇降路2が設けられている。また、建屋1の屋上に設けられたエレベーター用の機械室3には、エレベーターの駆動装置(図示せず)や制御装置4が設けられている。昇降路2内を昇降する乗りかご5は、駆動シーブ6に巻きかけられた主策7を介して吊り合いおもり8と連結されている。次に、各階床の乗場10と昇降路2との間のエレベーター出入口には乗場ドア9が設けられ、この乗場ドア9の乗場側には、火災時に昇降路2と乗場10との間で火または煙が流通するのを防ぐ防火防煙手段である防火防煙シャッター11が設けられている。この防火防煙シャッター11は、シャッター駆動装置12によって開閉される構成となっている。更に、建屋1の屋上に設けられた非常電源装置13は、バッテリーや発電機等で構成され、停電時、各階床に設けられたシャッター駆動装置12を駆動するようになっている。
【0011】
また、各階に設けられた火災検知器14で検知された情報が、通信回線を通して制御装置4内の乗りかご制御手段に送られ、この乗りかご制御手段が検知情報を用いて乗りかご5を休止させる階を特定すると共に、乗りかご5に対して当該階に休止するよう指令を出す。
【0012】
更に、乗りかご5が休止したことを検知する休止検知手段により、乗りかご5の休止が確認されると、当該休止情報を受信した駆動装置制御手段が、シャッター駆動装置12に対して閉じ指令を出す。
【0013】
ここで、駆動装置制御手段は、火災検知器14で検知された情報を受信して記憶する検知情報記憶手段と、この検知情報に基づいて火災階を特定する火災階特定手段と、この火災階特定手段で特定された階より上方の階のうち火災階に近い階の防火防煙シャッター11から順次閉じるように、各シャッター駆動装置12に対して閉じ指令を出すシャッター指令手段とから構成されている。
【0014】
以下、本発明の動作について、図2を用いて説明する。まず、建屋1内の各階に設けられた火災検知器14により火災かどうかの判定を行う(手順S1)。ここで、火災を検出しない状態ではエレベーターは正常な運転を行っていることになる。一方、火災が検出されると、乗りかご制御手段が乗りかご5を所定の階に休止させる(手順S2)。次に、休止検知手段により、乗りかご5がその所定階に休止したかどうかの判定がなされる(手順S3)。休止が確認されると、駆動装置制御手段がシャッター駆動装置12に対して閉じ指令を出し、出入口を防火防煙シャッター11で閉鎖し(手順S4)、火炎や煙が昇降路2内に侵入するのを防止する。
【0015】
以上のように、火災発生時、乗りかごに対して休止指令が出され、乗りかごが所定階に休止したことを確認した後に、防火防煙手段を閉じるため、火災発生時に乗りかご内にいた利用客が、乗りかご内に閉じ込められるという事態の発生を防止することができる。
【0016】
尚、本実施形態では、乗りかご5の休止後、防火防煙シャッター11を一斉に閉じるようにしたが、例えば、火災階が階床3である場合、階床4,階床5,階床2,階床1と順次閉じるようにしても良い。全ての階のシャッター駆動装置12を一斉に駆動させるのではなく、各階のシャッター駆動装置毎に1台ずつ駆動させるため、非常電源装置13の容量が不足するという事態も防止することができる。すなわち、シャッター駆動装置1台を駆動させるだけの少ない電源容量であっても、最終的に全ての階の防火防煙シャッター11を閉じることができる。また、上方の階床4,階床5の後、下方の階床2の順としたのは、火炎や煙は上方へ移動するためである。
【0017】
更に、乗りかご5の休止が確認された後、一定時間が経過してから防火防煙シャッター11が閉じるように駆動制御手段で制御することにより、利用客が乗りかご5から出る時間を十分確保することもできる。また、乗りかご5の休止後、乗りかご内から一定時間操作がなかった場合に、防火防煙シャッター11が閉じるように制御しても良い。もちろん、乗りかご内を監視して利用客がいないことが確認され次第、防火防煙シャッター11を閉じるように制御しても構わない。
【0018】
【発明の効果】
本発明によれば、火災発生時等に乗りかご内にいた利用客が、乗りかご内に閉じ込められるという事態の発生を防止することができる。

FIG. 1 is a longitudinal side view of an entire building including an elevator apparatus according to an embodiment of the present invention, and FIG. 2 is a flowchart showing an operation example of the present invention.
[0010]
In FIG. 1, a hoistway 2 for an elevator is provided on the side of a building 1 composed of a fifth floor. The elevator machine room 3 provided on the roof of the building 1 is provided with an elevator drive device (not shown) and a control device 4. A car 5 that moves up and down in the hoistway 2 is connected to a suspension weight 8 via a main measure 7 wound around a drive sheave 6. Next, a landing door 9 is provided at the elevator entrance between the landing 10 and the hoistway 2 on each floor, and the landing side of the landing door 9 is fired between the hoistway 2 and the landing 10 in the event of a fire. Or the fire prevention smoke prevention shutter 11 which is a fire prevention smoke prevention means which prevents that smoke distribute | circulates is provided. The fire and smoke proof shutter 11 is configured to be opened and closed by a shutter driving device 12. Furthermore, the emergency power supply device 13 provided on the roof of the building 1 is composed of a battery, a generator, and the like, and drives the shutter drive device 12 provided on each floor during a power failure.

In addition, information detected by the fire detector 14 provided on each floor is sent to the car control means in the control device 4 through the communication line, and the car control means pauses the car 5 using the detection information. The floor to be specified is specified, and the car 5 is instructed to stop on the floor.
[0012]
Further, when the stop of the car 5 is confirmed by the stop detection means for detecting that the car 5 is stopped, the drive device control means that has received the stop information issues a close command to the shutter drive device 12. put out.
[0013]
Here, the drive device control means includes detection information storage means for receiving and storing information detected by the fire detector 14, a fire floor specifying means for specifying a fire floor based on the detection information, and this fire floor. Shutter command means for issuing a close command to each shutter drive device 12 so as to close sequentially from the fire prevention smoke-proof shutter 11 of the floor close to the fire floor among the floors above the floor specified by the specifying means. Yes.
[0014]
The operation of the present invention will be described below with reference to FIG. First, the fire detector 14 provided on each floor in the building 1 determines whether or not there is a fire (procedure S1). Here, in a state where no fire is detected, the elevator is operating normally. On the other hand, when a fire is detected, the car control means stops the car 5 on a predetermined floor (step S2). Next, it is determined by the stop detection means whether or not the car 5 has stopped at the predetermined floor (step S3). When the stoppage is confirmed, the driving device control means issues a closing command to the shutter driving device 12, the entrance / exit is closed by the fire / smoke / shutter 11 (step S 4), and flame and smoke enter the hoistway 2.

For example, when the fire floor is the floor 3, the floor 4, the floor 5, the floor 2, it may be closed sequentially with the floor 1. Since the shutter driving devices 12 on all the floors are not driven all at once, but one shutter driving device on each floor is driven, it is possible to prevent a situation where the capacity of the emergency power supply 13 is insufficient. That is, even if the power supply capacity is small enough to drive one shutter driving device, the fire and smoke / shutter shutters 11 of all floors can be closed finally. The reason why the upper floor 4 and the lower floor 5 are followed by the lower floor 2 is that the flame and smoke move upward.
[0017]
Further, after confirming that the car 5 is stopped, the drive control means controls so that the fire and smoke prevention shutter 11 is closed after a certain period of time, thereby ensuring sufficient time for the passenger to leave the car 5. You can also In addition, after the car 5 is paused, it may be controlled so that the fire and smoke / shutter 11 is closed when there is no operation from the car for a certain period of time. Of course, as soon as it is confirmed that there is no passenger by monitoring the inside of the car, the fire and smoke prevention shutter 11 may be controlled to close.
[0018]
