2. Description of the Related Art For example, in an office elevator where there are no customers during the night, after a parking operation is performed at a predetermined time at night, the car stops at a predetermined parking floor and the elevator goes out of operation. As disclosed in, for example, Japanese Utility Model Application Publication No. 53-130772, this parking operation is started when a manager operates a parking switch installed at a designated parking floor of an elevator, and the car unloads the passenger. The elevator then travels to the parking floor, where the doors are closed, the lights inside the car are turned off, and the elevator is out of operation.

By the way, as disclosed in Japanese Utility Model Application Publication No. 60-78366, the above-mentioned parking switch is provided on a monitoring panel located away from the elevator landing, and the parking switch is remotely operated during parking operation. A method has been proposed.

0004

[Problem to be solved by the invention] When the parking operation is performed remotely using the method according to this proposal, the manager does not check on the parking floor to see if there are any passengers in the car. On the floor, customers may jump onto a car in a hurry that is about to go into idle mode. In such cases, after jumping on board, the elevator door closes, the lights inside the car go out, the elevator goes out of operation, and the passenger is sometimes trapped inside the car.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator operating system that prevents passengers from being trapped in a car that is out of operation due to parking.

[0006]

[Means for Solving the Problem] The object is to provide an elevator having a control circuit that includes a parking switch, and when the parking switch is turned on, the car moves to a predetermined parking floor and stops operating at that parking floor. In the driving device, the control circuit includes a circuit that puts an intercom in the car into a calling state by operating any button provided on the driving panel of the car after the car stops at the parking floor. This is achieved by

[0007]

[Function] With this structure, even if a passenger jumps onto a car that is about to go into suspension on the parking floor, and the elevator door immediately closes and the lighting inside the car goes out, the passenger will still be able to When you operate any button on the car's driving panel, the intercom inside the car goes into a ringing state. As a result, the passengers in the car that have entered the idle state are able to talk to the manager etc. through the intercom. A manager or the like who receives a call from the in-car intercom can cancel the operation suspension state, allowing the passenger to escape from the car.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit diagram showing an embodiment of the elevator operating system of the present invention, and FIG. 2 is a front view of the operating panel.

As shown in FIG. 2, in this embodiment, an intercom operation button INT and a speaker SP are arranged side by side near the upper end of the driver's panel 7 inside the car, and a door is arranged near the lower end of the driver's panel 7. An open button BO and a close button BC are provided for manual opening and closing operations. Further, car call registration buttons 1C to 3C are arranged vertically in the center of the operation panel 7, and an indicator lamp LU for indicating whether the car is ascending or descending is provided between the operation button INT and the speaker SP registration button 3C. LD is provided.

As shown in FIG. 1, a normally open contact PSWa of a parking switch (not shown) is connected between DC power supply terminals P and N.
and the parking operating device PA are connected in series with each other. In addition, between the normally open contact PSWa, the connection point of the parking operation device PA, and the DC power terminal N, a normally open contact PAb of a relay (not shown) for detecting the end of the parking operation, and a normally open contact Ra1 of the relay R. , the normally closed contact Tb2 of the timer T, and the relay R are connected in series with each other. Then, the normally open contacts 1Ca to 3Ca of the relay (not shown), which are energized by the operation of the car call registration buttons 1C to 3C, and the open button BO.
, a parallel connection circuit of normally open contacts BOa, BCa of a relay (not shown) that is energized by operating the close button BC, and normally open contact INTa of a relay (not shown) that is energized by operating the operation button INT. , are connected in parallel to the normally open contact Ra1.

[0012] Also, a relay R is connected between the DC power terminals P and N.
The normally open contact Ra2 of the timer T, the normally closed contact Tb1 of the timer T, and the lighting lamp LAMP in the car are connected in series with each other,
An intercom IN is connected in parallel to the lighting lamp LAMP. Similarly, between the DC power terminals P and N, a normally open contact Ra3 of the relay R and a timer T that operates after a predetermined time (for example, 20 minutes) are connected in series.

In an embodiment with such a configuration, the parallel connection circuit of the normally open contacts 1Ca to 3Ca, the normally open contacts BOa, BCa, and the normally open contact INTa and the relay R constitute the emergency response means of the present invention. There is.

Next, the operation of the embodiment will be explained.

When the parking switch is operated at a remote location to perform parking operation, the normally open contact PSWa is turned on, and the DC power terminal P, the normally open contact PSWa, the parking operating device PA, and the DC power terminal N are closed. A circuit is formed, the car is operated for parking, and the car arrives at the parking floor while dropping off passengers. Then, when the car stops at the parking floor, the elevator door opens, and a predetermined period of time has elapsed, the door closes, the lighting inside the car goes out, the elevator goes out of operation, and the normally closed contact PAb turns ON. .

[0016] In this case, immediately before the elevator door closes, the user does not know that the elevator will be out of operation.
If a passenger panics and jumps into the car, the elevator door closes immediately, the lights inside the car go out, and the elevator goes into a non-operating state. However, if the passenger operates any of the intercom operation button INT, door open button BO, door close button BC, or car call registration buttons 1C to 3C on the driving panel 7 in the car, the parallel circuit becomes conductive, so the DC power supply terminal P and the normally open contact P
A closed circuit is formed by SWa, the normally closed contact PAb, the parallel connection circuit, the relay R, and the DC power supply terminal N, and the relay R is energized.

When the relay R is energized in this way, the normally open contact Ra1 is turned ON and the relay R is self-held.
The normally open contact Ra2 is turned ON. When the normally open contact Ra2 turns ON, the DC power supply terminal P, the normally open contact Ra2, and the normally closed contact T
a1, the lighting lamp LAMP, and the DC power supply terminal N form a closed circuit. In addition, since a closed circuit is formed between the DC power terminal P, the normally open contact Ra2, the normally closed contact Tb1, the intercom IN, and the DC power terminal N, the in-car lighting lamp LAMP lights up, and the intercom IN enters the calling state. Timer T is activated by normally open contact Ra3 being turned on.
starts timing.

[0018] Then, the timer T is activated for a predetermined period of time (for example, 20
minute), normally closed contacts Tb1 and Tb2 are turned OFF, relay R is deenergized, lighting lamp LAMP is turned off, intercom IN is also turned OFF, normally open contact Ra3 is turned OFF, and timer T returns to its initial state. and normally closed contacts Tb1, Tb
2 is turned ON again.

In this way, according to the embodiment, a passenger who has jumped onto a car that is about to enter a suspension of operation on the parking floor presses the operation buttons INT, open button BO, and
When the close button BC or at least one of the car call registration buttons 1C to 3C is operated, the lighting lamp LAMP lights up and the intercom IN goes into the calling state, so even if the passenger is unfamiliar with elevators and is in a hurry, the lighting will be reliably turned on. Since the LAMP is lit and the intercom IN is in a calling state, the safety of the customers is guaranteed.

[0020]
