Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided in at least one of an elevator car and an elevator hall,
The present invention relates to a display device that displays an operating state of an elevator.

[0002]

2. Description of the Related Art Elevator display devices are generally classified into a display device installed in an elevator car and a display device installed in an elevator hall. In addition, as for the operation panel, there are ones in which a display device is provided with a push button and ones in which the display device is independent of the push button.

Now, the structure and operation of the operation panel will be described with reference to FIG. When the user presses the push buttons 6A and 6B on the operation panel 8, the elevator operation panel 8 starts operating up to the position (floor) where the elevator car is located.
The display device 4 is a position light 4 for displaying the position of the elevator car.
Directional light 4 indicating A and the direction of movement of the elevator car
B, 4C, and the current position of the elevator car is displayed on the position light 4A.

The user pushes the push buttons 6A, 6B on the operation panel 8
By pressing, the display of the position lamp 4A changes as the elevator car operates from the position at that time to the position where the user is. Also, the direction of movement of the elevator is direction light 4
It is displayed on B and 4C, and the display of the direction lights 4B and 4C disappears when it reaches the position where the user is. Then, depending on the direction of movement of the elevator car to which the user is heading, the direction lights 4B, 4
C lights up. For example, if the user is on the first floor and presses the push button 6A for UP (up) call, if the elevator car is located on the third floor, the push button 6A
By pressing, the display contents of the position light 4A is 3 → 2 → 1
And change sequentially. Also, the operating direction of the elevator car is
While moving from the third floor to the first floor, the direction light 4B in the DN (down) direction is displayed. After that, when the elevator car arrives on the first floor, the direction light 4B in the DN direction goes out, and the UP
Directional lights 4C are displayed.

Further, the operation panel 8 is provided with an indicator light 4D for displaying the status of the elevator such as full or emergency.
This indicator light 4D is not normally displayed, but is displayed when informing the user of the operating state of the elevator, such as when the elevator car is full.

By the way, an elevator has a possibility of being subjected to various external damages because it is operated by an unspecified number of people. For example, the operation panel installed in the car has a relatively high possibility of being misled by a careless person because the car is temporarily closed. Specifically, it is the act of melting (burning) the operation panel surface using a firearm such as a lighter. In response to such actions, the pushbuttons on the control panel, especially the push buttons, should be covered with a metal cover, and the display should be covered with a transparent or translucent material such as glass or polycarbonate, which is a flame-retardant plastic sheet. Was there.

[0007]

Of the above-mentioned measures, the method of covering with a metal cover is such that when the display does not change like a push button, it is possible to confirm that the surrounding area is illuminated and the button is pressed. However, in the case of a display device in which the display changes throughout, covering with a metal cover is not appropriate because the display of the display device cannot be seen.

Further, in the method of covering with a flame-retardant plastic sheet, when the surface of the display device is exposed to a flame for a long time, the heat may melt the flame-retardant plastic and the display on the display device behind may disappear. is there.

On the other hand, the glass material is strong against fire and allows light to pass through. However, the glass material is generally weak against impact, and it is necessary to increase the plate thickness in order to have rigidity to some extent, and the degree of freedom in design is poor. Become. Furthermore, even if tempered glass is used for the glass material, it will crack when it is impacted by a sharp object,
It becomes less durable and may crack from there.

The present invention has been made in consideration of such problems, and an object thereof is to provide an elevator display device capable of improving fire resistance without impairing the visibility of the display and the rigidity of the device. And

[0011]
