る。As is well known, an elevator is provided with a door for each car and the landing, and when the car reaches a floor, the car door opens, and at the same time, the door to the landing opens. However, if the door sill is clogged with trash or the interlocking mechanism between the car door and the landing door malfunctions, the car will stop at that floor with the door closed. As a result, the passengers inside the car were left trapped inside the car for a long time, with no other option than to anxiously wait for someone to rescue them. This invention is intended to improve the above-mentioned problems, and an object of the present invention is to provide an operating device that can prevent the elevator car from becoming stuck with passengers trapped in it even if the door of the elevator car cannot be opened.

ものである。If the car floor is approximately 20 degrees above and below the second floor floor, the door-openable section detection switch 10 is closed, and the [+)-9-10-5
The door opening relay 4 is energized by the circuit c-2d-4-3a-(-) and the door begins to open. At the same time, the contact 4b opens and the time limit relay 1 counts the time limit, but if the door is normal, the door will finish opening before the time limit relay 1 returns, the fully open detection switch 9 will open, and the door opening relay 4 will open. disappears,
Contact 4b is closed. Therefore, the time relay 1 is energized again, the contact 1a remains open, and the door abnormality detection relay 2
is not energized. Even if the door finishes opening and the relay 4 is de-energized, the door-opening time control time relay contact 12a remains open until a certain period of time (4 to 6 seconds) elapses, so the command relay 5 is not energized. The door is held open. Eventually, when the above-mentioned time limit elapses and the contact 12a is closed, the command relay 5 is energized by the (+)-11-4c-12a-5-(-) circuit, and the contact 5b is closed. (+
)-8-5b-3-4a-(-), the door closing relay 3 is energized and the door begins to close. When the door is completely closed, the fully closed detection relay 8 is opened and the door closing relay 3 is deenergized. When it is detected that both the car door and the landing door have been closed, the car departs in response to the next call. However, even though the car has landed on the floor and the door opening relay 4 is energized, the threshold of the door is clogged with garbage, and the landing door is opened in conjunction with the car door. Suppose that the door does not open completely due to a device malfunction or some other reason. When the contact 4b is opened, the time relay 1 counts the time limit, and eventually returns to close the contact 1a. (Saw 6a-7a-1a-2-
The abnormality detection relay 2 is energized by the (-) circuit and self-maintained by closing the contact 2a. Further, since the door opening relay 4 is deenergized by opening the contact point 2d, the door opening operation is immediately stopped, thereby preventing burnout of the door driving motor. At the same time, contact 2b is closed and (+)-11-4c-2b-5
The command relay 5 is energized by the -(-) circuit, so the door starts closing. At the same time, contact 2c is closed. If the car position is currently on the 2nd floor, the car position switch 2F
Since a is open and switch 1Fa is closed, (+
)-2c-1Fa-15b-13a-141(-) activates the descending direction command relay 14 even if there is no other call registration, and when it is detected that the door has finished closing,
The car automatically begins descending operation. However, there may be other passengers on board who are going to other floors, so if there is a call for a destination on another floor, the train will respond to the call and depart. When the car starts descending operation, the descending operation relay contact 7a opens, so the detection relay 2 is deenergized. Although the details are omitted, the car lands on the next floor (in this case, the first floor), and the door opens as usual on the floor where it landed, allowing the passengers inside the car to be safely rescued. At this time, when an abnormality is detected in the door on the second floor, the detection relay contact 2e closes and the car position switch 2Fb closes, so (+)
-15c-2e-2Fb-2N-(-) circuit,
Abnormal floor detection relay 2N is energized and self-holds by closing contact 2Na. Also, since contact 2Nb is also closed,
The abnormality alarm buzzer 2B on the second floor sounds, and the abnormality warning light 2L lights up to notify that there is an abnormality in the door on the second floor. If this information is notified not only at the landing, but also inside the car, in the manager's room, etc., failures can be discovered quickly and repairs can be completed quickly, so users are not inconvenienced for a long time. During this failure period, the contact points of the abnormal floor detection relays 1N to 6N are used to disconnect the call relays (not shown) that perform call registration using the respective call buttons in the hall and in the car, and Inconvenience to customers can be minimized by disabling only the call registration and continuing car service to floors other than the failed floor. When a failure is detected or the automatic operation is switched to manual operation for repair, the automatic operation relay contact 15c is opened and the detection relay 2N is deenergized and reset. In the above explanation, we explained an example in which when a failure occurs, the vehicle is operated to the next floor below the failure floor, but in general, in a building, the floor (usually the first floor) is the reference floor for communication with the outside of the building. People move around the center, and the building manager (who often also serves as the elevator manager) is usually stationed near this standard floor, so the building manager moves the car toward this standard floor. This is for the convenience of reporting, etc.

同様の目的で、次の階に着床させず、基準階等の特定の
階へ直接かごを運転し、特定階にて乗客を救出して管理
人への故障通報を迅速に行なわせるよう構成することは
容易である。目的の階床へ行こうとする乗客の便宜を考
えれば、目的の階床への利用が不可能の場合目的の階床
の１階下から重い荷物を持つて階段を昇ることを考えれ
ば、むしろ１階床上方の階でかごを降りて、階段を降り
る方が好ましい場合もある。For the same purpose, the car is configured to drive the car directly to a specific floor such as a standard floor without landing on the next floor, rescue passengers on the specific floor, and promptly report the failure to the manager. It's easy to do. Considering the convenience of passengers trying to get to their destination floor, if it is not possible to use the destination floor, it would be better to consider carrying heavy luggage and climbing the stairs from one floor below the destination floor. In some cases, it may be preferable to get off the car at a floor above the first floor and go down the stairs.

このような要求に対して、例示とは逆に故障階よりも上
方の階へかこを運転して乗客を救出するよう構成するこ

するかはエレベータの設置されるビルの要求に応じて選
択されるべきである。In response to such a request, contrary to the example illustrated, a structure can be easily obtained in which the passenger is rescued by driving the car to a floor above the faulty floor by partially modifying the illustrated example. In this way, when a failure occurs on a certain floor, whether the elevator automatically operates to the next floor below or above the failure floor, or to a specific floor depends on the requirements of the building where the elevator is installed. should be selected accordingly.

閉接点である。FIG. 3 is a diagram showing another embodiment of the present invention, which is the same as FIG. 1 except for what is shown. In the figure, 2c, 2f to 2h are normally open contacts of the door abnormality detection/relay 2 in Figure 1, 6c is a lift operation relay contact that closes when the car is in lift operation, similar to contact 6b in Figure 1, and 7c is a Lower operation relay contacts 12b and 12c, which are the same as contact 7b in FIG. 16a is the normally open contact of the upward driving direction memory relay, 16b, 1
6c is also a normally closed contact, 17 is a descending operation direction memory relay, 17a is its normally open contact, and 17b and 17c are also normally closed contacts.

が生じる。As explained in Figure 1, if a failure occurs on a certain floor,
If you decide to drive the car in a predetermined direction (upwards, downwards, to a specific floor, etc.), for example, it has climbed from the 1st floor to the 5th floor, but the 5th floor is broken. Because it was so hot, we had to go back to the 4th floor and go down, or conversely, even though we had come down from the 8th floor to the 3rd floor, there was a malfunction on the 3rd floor, so we went back up to the 4th floor. Something happens.

していると、上昇運転リレー接点６ｃが閉成するので、
上昇運転方向記憶リレー１６は付勢され、接点１６ａは
閉成する。In such a case, since the elevator automatically starts driving in the opposite direction to the direction in which the elevator has been driving, some passengers may feel creepy and fear the elevator.
Taking these psychological aspects into account, the car remembers the driving direction when arriving at the faulty floor and automatically runs the car in the same direction as that driving direction, except for the top and bottom floors. , it is possible to rescue the passengers. FIG. 3 shows this embodiment. Now, when the ascending operation is performed from the first floor to the second floor, the ascending operation relay contact 6c closes.
The upward driving direction memory relay 16 is energized and the contact 16a is closed.

いることになる。Further, the contacts 16b and 16c are open. Eventually, when you arrive at the second floor of your destination, the door opening time control time relay contact 12b is closed, so (+)-12b-16a-
The relay 16 continues to be energized by the circuit 17b-16-(-). If the door on the second floor does not finish opening even after a certain period of time has elapsed, the door abnormality detection relay 2 is energized, the contact 2f is closed, and even if the contact 12b is opened, the memory relay 16 continues to be energized. This means that the driving direction when arriving at the failure floor is memorized.

By opening 6c, the downward travel command relay 14 is not energized even if the abnormality detection relay contact 2c is closed. That is, (+)-2h-17c-6Fa-15a-14a-
13-(-) circuit causes upward direction travel command relay 1.
3 is energized, it automatically starts operating in the same direction as when it landed on the second floor. In the embodiment shown in FIG. 3, if the floor on which the abnormality detection circuit operates is the top floor or the bottom floor, the vehicle is caused to run in the opposite direction to the direction in which it has been running up to that point.

Ｎｄ〜５Ｎｄは同じく異常階検出リレー２Ｎ〜５Ｎの常
閉接点である。Other than what is shown, the configuration is the same as in FIG. 1. In the figure, 1NC to 6NC
are normally closed contacts of abnormal floor detection relays 1N to 6N in Fig. 2, 2
Similarly, Nd to 5Nd are normally closed contacts of abnormal floor detection relays 2N to 5N.

５階で故障が発生すれば、５階の異常階検出リレー５Ｎ
が付勢され、接点５Ｎｃ，５Ｎｄは開放する。If a failure occurs on the 5th floor, the 5th floor abnormality detection relay 5N
is energized, and contacts 5Nc and 5Nd are opened.

常階の呼びを登録しないようにすることも簡単である。Therefore, even if the destination button on the 5th floor is pressed and the car call relay contacts 5Ka and 5Kb are closed, the command relay 13
, 14 are not energized, so the car does not respond to calls from the fifth floor. Since the abnormal floor detection relay contacts 2Nc and 2Nd on a non-faulty floor, such as the second floor, are closed, it is possible to normally respond to calls. Although it has been explained that the car does not respond to the call even if the car call relay is energized, it is also easy to prevent the call from the abnormal floor from being registered by operating the abnormal floor detection relays 1N to 5N.

のが通例である。In each of the above embodiments, it has been explained that the call registration for the floor where the failure has occurred is disconnected and the service is provided to passengers who use the elevator to travel to other floors. Generally, the car side has a drive mechanism for driving the door, and the door on the landing side is opened and closed by engaging with the door of the car.

したがつて、乗場側の戸の機構に何らかの異常がある場
合は、特定階の戸だけ開かないことになるが、かご側の
駆動機構や戸の機構に異常がある場合は、特定階だけで
はなく、他の階へ行つても戸が開かないことも十分考え
られる。Therefore, if there is any abnormality in the door mechanism on the landing side, only the door on a specific floor will not open, but if there is an abnormality in the drive mechanism or door mechanism on the car side, it will not open only on a specific floor. There is a good chance that the door will not open even if you go to another floor.

間に停止してしまうカンズメ事故等の二次事故も考えら
れるので好ましくない。In this case, repeatedly operating the elevator in search of a floor where the door can be opened may cause a burnout accident due to overheating of the main motor driving the elevator, or the elevator may stop in the middle of the floor due to activation of an overcurrent relay. This is not preferable because it may cause secondary accidents such as a kanzume accident.

第５図はこの対策の一実施例である。FIG. 5 shows an example of this measure.

複数階床異常検出リレー１８は、抵抗Ｒ１〜Ｒ６のうち
所定数、例えば２個が短絡されたとき付勢されるように
調整されている。The multi-story abnormality detection relay 18 is adjusted to be energized when a predetermined number, for example, two of the resistors R1 to R6 are short-circuited.

今、かご側の戸に異常が発生し、これが２階で検出され
ると、異常階検出リレー接点２Ｎｅは閉成する。If an abnormality occurs in the door on the car side and is detected on the second floor, the abnormal floor detection relay contact 2Ne closes.

な構成とすることが可能である。Next, when the car is driven to the third floor, if the above-mentioned abnormality has not been recovered, the contact 3Ne is closed in the same manner. Now, since resistors R2 and R3 are shorted, the detection relay 18
is energized. As a result, the call registration relay and the operation relay (both not shown) are not energized. That is, wasteful operation is prevented by an operation prevention circuit (not shown). At the same time, the abnormality alarm buzzer 2 explained in Fig. 2
It is obvious that it would be even better if the abnormality was reported using the B1 abnormality warning light 2L or the like. In addition to the measures shown in Figure 4,
When an abnormality is detected, the time limit until the car starts running next time may be extended beyond the normal time limit, and an economical configuration is possible.

なお、上記各実施例は６階のビルについて説明したが、
階床数には関係なく適用できることは明白てある。Note that each of the above embodiments was explained for a 6th floor building, but
It is clear that it is applicable regardless of the number of floors.

また、第１図、第３図及び第４図はかご呼びについて説
明したが、乗場呼びについても同様に適用できることは
言うまでもない。Moreover, although FIGS. 1, 3, and 4 have been described with respect to car calls, it goes without saying that they can be similarly applied to hall calls.

Since the operation is prevented and the above-mentioned abnormality is reported, it is possible to prevent the car from becoming stuck while the passenger is trapped in the car, and the passenger can be rescued quickly.
