Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor display device for an elevator, and more particularly to a floor display device for an elevator which is suitable for a failure.

[0002]

2. Description of the Related Art When an elevator fails and the car stops on an intermediate floor, a confinement failure occurs in which passengers in the car are confined. In order to rescue the passengers, this trapping failure causes the door to be opened when the car happens to stop within the door openable / closeable range (usually about ± 30 cm), as disclosed in Japanese Patent Laid-Open No. 52-133646. It can open automatically and rescue passengers. However,
The door cannot be opened when the vehicle stops outside the above-mentioned door openable range. Therefore, the elevator manager contacts the maintenance company, the maintenance engineer rushes to the site, and manually rescues the car to the nearest floor.

[0003]

By the way, when the failed elevator is in a remote area, it may take a long time from when the maintenance engineer is contacted to when the maintenance engineer arrives at the site. Therefore, there is a problem that the passengers are locked in the car for a long time, and during that time, the passengers feel anxious.

In view of the above-mentioned drawbacks, the present invention, when a containment failure occurs, in the case of a safe door opening range even if the door is opened, the floor indicator lamp of the hall is blinked and displayed, and the manager To provide a floor display device for an elevator that can rescue passengers in a short time by opening the door.

[0005]

The object of the present invention is to provide an elevator car for working on floors of a plurality of floors, and an elevator floor display device for displaying the car position of the car by illuminating an indicator light provided at the hall. , Equipped with a device that detects that the car has stopped due to a failure, and when this detection device operates, if the floor closest to the position where the car stopped is within a predetermined distance, This is achieved by including means for blinking and displaying the indicator lamp.

[0006]

According to the present invention, it is assumed that a failure occurs and the car stops at the middle floor. When the passenger contacts the manager through the intercom, the manager can first look at the floor display device to know where the car is stopped. At this time, if the indicator light is blinking and lighting, it can be seen that the car is stopped in the rescue range, so the manager unlocks the blinking and lighting door and opens the door to open the passengers. It can be rescued safely and in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Incidentally, the elevator shall be in service on the first to fourth floors.

FIG. 2 is a front view of the floor display device provided in the hall. In the figure, D is a door, I is a floor display device, and the floor display device I is provided with indicator lights 1L to 4L for displaying the car position of the elevator. The display lights 1L to 4L are designed so that the display can be switched between the floors and the intermediate position between the floors.

FIG. 1 is an electrical connection diagram of a floor display device for an elevator according to an embodiment of the present invention. In the figure, P and N are DC power supply terminals, 10a is an a contact that is closed when a failure occurs in the elevator, and 11 is a contact 10
A relay is energized when a is closed. 11a is its a contact, 11b is its b contact, and FA is a blinking device. F1
Floor selector fingers that move synchronously with the car, 1S1
4S1 is a segment of the floor selector embedded in the floor positions of the 1st to 4th floors, and the indicator lights 1L to 4L are connected to the segments 1S1 to 4S1. When the car moves, when the finger F1 contacts the segments 1S1 to 4S1 and, for example, the finger F1 contacts the segment 3S1, the indicator light 3L is lit by the circuit P-11b-F1-3S1-3L-N, and the car It is located on the 3rd floor. In addition, this segment 1S1-4S1
Since the arrangement of is embedded up to the middle of the floor,
For example, the fact that the indicator light 3L on the third floor is lit indicates that the car is somewhere in the middle position between the third floor and the fourth floor rather than the middle position between the second floor and the third floor. F2 is a finger of the floor selector, 1S2 to 4S4 are segments embedded in the floor positions of the first to fourth floors, and the segments 1S1 to 4S1
And the segments 1S2 to 4S2 are connected in parallel. And the arrangement of the segments 1S2-4S2 is
It is embedded so that passengers can be safely rescued even if the door is opened, that is, about 1.5 m below the floor and about 1 m above the floor.

Next, the operation of this embodiment will be described.

First, the case of normal operation will be described. In this case, since no failure has occurred, the contact 10a is open. Therefore, since the relay 11 is deenergized, the contact 1
1a is open, finger F2 is invalid, and finger F1 is valid. When the car is stopped on the first floor, the finger F1 comes into contact with the segment 1S1 and the indicator light 1L on the first floor is lit. When the car rises and passes the middle position between the first floor and the second floor, the finger F1 comes into contact with the segment 2L, so that the indicator lamp 2L is turned on. Similarly, the indicator lights 3L and 4L are turned on to display the car position.

Next, it is assumed that a car breaks down and the car stops 1 m before the floor on the third floor. The contact 10a is closed and the relay 11a is energized. Then, the contact 11b opens, the finger F1 becomes invalid, and the finger F2 becomes valid. At this time, the finger F2 comes into contact with the segment 3S2 and the P-FA
The indicator lamp 3L blinks and lights up by the circuit of -11a-F2-3S2-3L-N. Thereupon, the manager can unlock the door D on the third floor and open the door D by seeing the indicator light 3L blinking and illuminating, and rescue the passengers in the car.

Next, a failure occurs and, as shown by the dotted line,
Suppose the car stops midway between the 1st and 2nd floors. In this case, the finger F2 does not come into contact with any of the segments 1S2, 2S2, and it is known that unlocking the door D is dangerous, and the manager notifies the maintenance company to request the rescue of the passengers.

In the above embodiment, the case where the car position is displayed using the floor selector has been described.
The same effect can be obtained by using a rotary encoder for the drive motor and setting the blinking count number in advance.

In this way, when a failure occurs and a confinement failure occurs, it is possible to know whether or not the manager can rescue the person by looking at the floor display device, and the rescue time can be significantly shortened.

[0016]

As described above, according to the present invention, when a containment failure occurs, it is possible to easily see whether the door can be unlocked by looking at the indicator light of the floor display device. This has the effect of significantly shortening the rescue time for passengers.
