【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】
また、火災発生時、安全な避難階に乗りかごを停止させ、乗りかご内にいる利用客を避難させる制御を行う方法が提案されている(例えば、特許文献2参照)。
【0004】
【特許文献1】
特開2001−276243号公報(第6図)
【特許文献2】
特開平10−182029号公報(第2−3頁)
【0005】
【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、避難階を特定し、この階に乗かごを移動させて、乗りかご内の利用客を避難させる場合、この乗かごが避難階に移動し、利用客が乗りかごから出た後でなければ全てのシャッターを閉じることができなかった。すると、火災発生からシャッターが閉じるまでに時間がかかり、昇降路内に煙が充満し、避難する利用客に害を与えるばかりか延焼を生じさせるという恐れがあった。
【0006】
したがって、本発明の目的は、昇降路内への煙の充満を防止または少なくすると共に、延焼を早期に防止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。
【0007】
【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、火災時に乗りかご内にいる利用者を避難させる避難階以外の階の防火防煙手段を閉じるようにしたことを特徴とする。
【0008】
上述した構成によれば、火災発生時、避難階を特定し、その特定の階以外の階の防火防煙手段を閉じるようにしたため、建屋側から昇降路内へと火炎や煙が侵入することが防止され、乗かごで避難階へ避難する利用客の安全を確保できるばかりか、昇降路から他の階への延焼を早期に防止できる。
【0009】
【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。
【0010】
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。
【0011】
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。
【0012】
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内のシャッター制御手段に送られ、この制御手段が検知情報を用いて火災階や避難階を特定すると共に、防火防煙シャッター11を動作するようシャッター駆動装置12へ指令を出すようになっている。
【0013】
ここでシャッター制御手段は、火災検知器14で検出された検知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に基づいて乗りかごの避難階を特定する非難階特定手段と、この避難階特定手段で特定された階以外の階の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、火災検知器14の検知情報に基づき火災階を特定し(手順S2)、その場合に利用客が避難するのに最適な階を避難階として特定する(手順S3)。例えば、階床3で火災が発生した場合は、下階の階床1を避難階として特定する。次いで、階床1以外のシャッター駆動装置12を駆動させ、避難階1以外の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】
そして、制御装置4からの要求があれば、避難階1の防火防煙シャッター11を閉じるようにする(手順S5)。例えば、乗かご5が避難階1に移動して利用客が降りたことを制御装置4が確認した後、避難階1のシャッター駆動装置12に対して閉じ指令を出すようにしても良い。尚、乗かご5が停止してから一定時間経過後に、自動的に防火防煙シャッター11を閉じるようにしても構わない。
【0016】
このように、火災発生時、避難階1を特定した後すぐに他の階2〜5の防火防煙シャッター11を閉じるようにしたため、建屋側から昇降路2内へと火炎や煙が侵入することが防止され、火災発生時に乗かご5内にいる利用客が避難階1へ避難する安全を確保できるばかりか、昇降路2から他の階2〜5への延焼を早期に防止できる。
【0017】
尚、本実施形態では、避難階1以外の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、階床4,階床5,階床2の順の如く、火災発生の近傍の階床から遠方の階床へと順次閉じるようにしても良い。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。
【0018】
また、火または煙の流通を防ぐ手段として、スクリーンやドアを用いても構わない。
【0019】
【発明の効果】
本発明によれば、火災発生時、建屋側から昇降路内へと火炎や煙が侵入することが防止され、乗かごで避難階へ避難する利用客の安全を確保できるばかりか、昇降路から他の階への延焼を早期に防止できる。

In an elevator apparatus provided with a drive device for opening and closing the means, the fire and smoke prevention means on a floor other than the evacuation floor for evacuating a user in the car in the event of a fire is closed.
[0008]
According to the above configuration, when a fire occurs, the evacuation floor is specified, and the fire and smoke prevention means on floors other than the specific floor are closed, so that the flame or smoke enters the hoistway from the building side. This prevents not only passengers evacuating to the evacuation floor by car but also safety from spreading from the hoistway to other floors at an early stage.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an elevator device of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is a vertical sectional 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.
[0011]
In FIG. 1, a hoistway 2 for an elevator is provided on the side of a building 1 having a five-story floor. An elevator driving device (not shown) and a control device 4 are provided in an elevator machine room 3 provided on the roof of the building 1. The car 5 that moves up and down in the hoistway 2 is connected to a suspended weight 8 via a main measure 7 wound around a drive sheave 6. Next, a landing door 9 is provided at an elevator doorway between the landing 10 on each floor and the hoistway 2, and a fire between the hoistway 2 and the landing 10 during a fire is provided at the landing side of the landing door 9. Alternatively, a fireproof smokeproof shutter 11 which is a fireproof smokeproof means for preventing the distribution of smoke is provided. The fire and smoke prevention shutter 11 is configured to be opened and closed by a shutter drive device 12. Further, the emergency power supply device 13 provided on the roof of the building 1 is configured by a battery, a generator, and the like, and drives the shutter drive device 12 provided on each floor during a power failure.
[0012]
Further, information detected by the fire detector 14 provided on each floor is sent to shutter control means in the control device 4 through a communication line, and the control means specifies a fire floor and an evacuation floor using the detection information, and A command is issued to the shutter driving device 12 to operate the fire and smoke prevention shutter 11.
[0013]
The shutter control means includes detection information storage means for receiving and storing the detection information detected by the fire detector 14, fire floor identification means for identifying a fire floor based on the detection information, and fire floor identification means. Means for specifying the evacuation floor of the car based on the floor specified by the means, and a shutter command for issuing a closing command to the shutter drive device 12 on a floor other than the floor specified by the evacuation floor specification means. Means.
[0014]
Hereinafter, the operation of the present invention will be described with reference to FIG. First, a fire detector 14 provided on each floor in the building 1 determines whether or not a fire has occurred (step S1). Here, when no fire is detected, the elevator is operating normally. On the other hand, when a fire is detected, a fire floor is specified based on the detection information of the fire detector 14 (step S2), and in that case, a floor optimal for evacuation of the user is specified as an evacuation floor (step S3). ). For example, when a fire occurs on the floor 3, the lower floor 1 is specified as the evacuation floor. Next, the shutter drive device 12 other than the floor 1 is driven, and the entrance other than the evacuation floor 1 is closed with the fireproof and smokeproof shutter 11 (procedure S4) to prevent the flame and smoke from entering the hoistway 2. .
[0015]
Then, if there is a request from the control device 4, the fire and smoke prevention shutter 11 on the evacuation floor 1 is closed (step S5). For example, after the control device 4 confirms that the car 5 has moved to the evacuation floor 1 and the passenger has descended, a closing command may be issued to the shutter driving device 12 of the evacuation floor 1. Note that the fire and smoke prevention shutter 11 may be automatically closed after a lapse of a predetermined time from the stop of the car 5.
[0016]
As described above, when a fire occurs, the fire and smoke prevention shutters 11 of the other floors 2 to 5 are closed immediately after the evacuation floor 1 is specified, so that the flame or smoke enters the hoistway 2 from the building side. This prevents the passengers in the car 5 from evacuating to the evacuation floor 1 in the event of a fire, and also prevents the spread of the fire from the hoistway 2 to the other floors 2 to 5 at an early stage.
[0017]
In the present embodiment, the fireproof and smokeproof shutters 11 other than the evacuation floor 1 are closed all at once. However, for example, floors near the fire occurrence, such as floor 4, floor 5, floor 2 You may make it close from a floor to the floor far away. 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.
[0018]
Further, a screen or a door may be used as a means for preventing the distribution of fire or smoke.
[0019]
【The invention's effect】
According to the present invention, in the event of a fire, flames and smoke are prevented from entering the hoistway from the building side, so that not only can the safety of users evacuating to the evacuation floor by car be ensured, but also from the hoistway The spread of fire to other floors can be prevented at an early stage.
