【考案の詳細な説明】
本考案はエレベータの安全装置に係り特に停電と同時に
乗かご内に停電発生の表示と放送を伝達するエレベータ
の安全装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator safety device, and more particularly to an elevator safety device that transmits an indication and announcement of the occurrence of a power outage to a passenger car at the same time as a power outage.
一般のエレベータでは停電が起ると運転中の乗かごは急
停止し利用者はかご内に閉ぢ込められる。In a regular elevator, when a power outage occurs, the car in operation suddenly stops, trapping the user inside the car.
このためかご内にインターホン等を取付けて外部との連
絡が行なえるようにしているが、突発的な故障のために
連絡がとれないことがある。For this reason, an intercom or the like is installed inside the car so that communication with the outside world can be established, but there are cases where communication cannot be established due to a sudden breakdown.
従ってその間利用者に不安感を与え精神的な動揺も大き
く、二次的災害を招くおそれがあり安全性の点から不具
合であった。Therefore, during this period, the user feels anxious and suffers from a great deal of mental turmoil, which may lead to secondary disasters, which is a problem from a safety point of view.
本考案は上記の点に鑑み威されたもので停電と同時に急
停止したかご内に停電発生の表示および放送を行ない利
用者の不安感を速かに取除き安全な処置が行なえるエレ
ベータの安全装置を提供するものである。This invention was developed in view of the above points, and is an elevator safety system that displays and broadcasts the occurrence of a power outage to the car that suddenly stops at the same time as a power outage, quickly removing the user's anxiety and allowing safe measures to be taken. It provides equipment.
以下本考案の一実施例を図面により説明する。An embodiment of the present invention will be described below with reference to the drawings.

字あるいは標識等で停電の表示を行なう。11b2 is the normally closed contact E of the relay 11, the emergency power supply, P',
N' is an emergency power bus that is charged when the normally closed contacts 1l-bl and 1l-b2 are closed, and 12 is a weight detection device that detects the weight of the car and closes the contacts when there is even one passenger. Switch 13 is a weight detection relay connected in series with switch 12 between bus bars P' and N', 13-al, 13
a2 is the normally open contact of the weight detection relay, 14 is the bus bar P',
A display device 14 is connected in series with the normally open contact 13 al between N' and, when energized, displays a power outage indication in the car using letters or signs.
１５は母線Ｐ’、 Ｎ’間に常開接点１３−ａ２と直列
に接続された放送装置、この放送装置１５は付勢される
と乗かご内に予め組込んだテープ等で停電発生の放送を
行なう。Reference numeral 15 denotes a broadcasting device connected in series with a normally open contact 13-a2 between bus lines P' and N'. When energized, this broadcasting device 15 broadcasts the occurrence of a power outage using a tape or the like installed in the car in advance. Do the following.
すなわち、エレベータ駆動用電源の停電により制御電源
母線Ｐ、 Ｎが無電圧になるとリレー１１の励磁が解か
れて接点１１−ｂ、、 １ｌ−ｂ２が閉ぢ非常電源用母
線Ｐ’、 Ｎ’が充電される。That is, when the control power buses P and N become non-voltage due to a power outage of the elevator drive power supply, the relay 11 is de-energized, contacts 11-b, 1l-b2 are closed, and the emergency power buses P' and N' are closed. It will be charged.
−古来かごに利用者がいると重量検出スイッチ１２は閉

が伝達される。- Traditionally, when there is a user in the car, the weight detection switch 12 is closed, so the weight detection relay 13 is energized and its contact 1
3-al and 13-a2 are closed, the display device 14 and the broadcast device 15 are operated, and the display and broadcast of the occurrence of a power outage are transmitted to the inside of the car.
また乗かご内に人が全くいないときは重量検出スイッチ
１２が切れているので母線Ｐ’、 Ｎ’が充電されても
重量検出リレー１３は励磁されず、従って表示装置１４
および放送装置１５は動作しない。Furthermore, when there is no person in the car, the weight detection switch 12 is turned off, so even if the bus bars P' and N' are charged, the weight detection relay 13 is not energized, and therefore the display device 14 is not energized.
And the broadcasting device 15 does not operate.

る。As described above, according to the present invention, the occurrence of a power outage is displayed and broadcast to the users in the car that suddenly stopped at the same time as the power outage occurs, so there is no feeling of anxiety at all to the users.
Post-processing can be carried out safely under normal conditions and secondary disasters can be prevented.Also, when a power outage occurs and there is no one in the car, both the display device and the broadcast device are not energized, so they are unnecessary. It has the effect of not performing any negative actions.
