Abstract

PURPOSE:To indicate a plurality of indicating windows by means of one sort of light source in an indicator for an elevator using an electroluminescent lamp for light source by combining a light emitting surface and an insulation coating part of a unit size to be a unit constitution. CONSTITUTION:An electroluminescent lamp (EL) 1 consists of a light emitting surface 2 and an insulation coating part 3 for a unit constitution. The size of the light emitting surface 2 is similar to the size of an indicator part to be a base, and a plurality of these combined with each other are manufactured using dies. For using this for light source, the insulation coating 3 is cut by means of scissors, a cutter, etc., as required corresponding to the size of the indicator part. Fixing method for the EL1 becomes easy by this. In manufacturing the EL1, dies are only of one short of a size of a plurality of the EL1 of the size of a unit indicator part combined with each other, thereby mass production becomes possible.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an elevator display device with a flat display.

[Conventional technology]

The structure of a conventional elevator display device will be explained with reference to FIG.

FIG. 5 shows an elevator display device with a flat display. In FIG. 5, the elevator display device 5 is
Although not shown, it is buried in a building or attached to a panel, etc. It includes a box with an opening on the - side and a cover 7 attached to the box opening with screws 8. This cover 7 is an EL (electroluminette lamp or lower)
) 1, a dial plate 8, and a display window 6, and the display window 6 is structured to display information such as a control operation display and a position display of the car.

Incidentally, examples related to this type include, for example, Utility Model No. 60-1
No. 45164 etc. are mentioned.

[Problem to be solved by the invention]

In the above conventional technology, the display part of the display window 6 and the ELL of the light source
The size is used in a one-to-one combination of length L2 and width L□. If the display content of the display area increases and one display area becomes larger than the basic size, length L2 and width L1,
A large EL is also required as a light source. Accordingly, molds of two different sizes are required for manufacturing EL.

Furthermore, EL of the basic size and E of the increased display content
Even if L is divided into two pieces, two types of molds are required. Also E
If L is divided into two pieces, the two ELs must be individually fixed with screws or the like to prevent the upper EL from falling down, which makes the structure more complicated and increases the time required for assembly.

For the reasons mentioned above, the EL used as an elevator display device has a problem in that the display contents are diverse, and if a mold is manufactured each time, mold costs are required, making it difficult to mass produce and making it expensive.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator display device equipped with an EL that can correspond to the display portions of a plurality of display windows with one type of EL.

[Means to solve the problem]

The above object is achieved by using EI, which is a light source for an elevator display device, in which a light emitting surface corresponding to the size of the basic display part and an insulating coating are combined into one structure, and many sets of these are combined. .

[Effect]

The EL light source has a light emitting surface and an insulating coating part as one structure.

The size of the light emitting surface is the same as the size of the basic display part, and a hairstyle is produced by combining many of these. When using it as a light source, use scissors, a cutter, etc. to cut the insulating coating according to the size of the display area. This simplifies the method of fixing the EL. Also E
When manufacturing L, only one type of mold is used, which is a combination of several EL sheets of the size of the basic display area, so mass production is possible.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

1 and 2 show an EL according to the present invention.

A lead wire 4a for power supply is provided on the light emitting surface 2a of the ELL. An EL according to an embodiment of the present invention uses this as a basic configuration, and has three light-emitting surfaces 2 arranged with a certain gap and both surfaces covered with an insulating coating 3.

FIGS. 3 and 4 show an elevator display device equipped with an EL according to the present invention, which is a device that displays inside the car that control operations such as earthquake control, fire control, private power generation control, etc. are in progress. . On top of the ELL, a dial 8 made of opalescent acrylic painted black with only the text portions outlined in white, and a display window 6 made of heat-absorbing acrylic are stacked on top of each other, and the four corners are held down by covers 7. It is fixed to the panel 10 with mounting screws 9. Normally, the display parts for earthquake control, fire control, and private power generation control are made to have the same size for visibility, and the light emitting surfaces 2a, 2b, and 2
c are arranged side by side. For example, in order to display earthquake control operation, if power is supplied from the external lead wire 4a, the light emitting surface 2a will emit light, only the white characters on the dial 8 will transmit light, and the 1 display character will indicate an earthquake. It is possible to display that the vehicle is under controlled operation. Similarly, it is possible to display fire control and private power generation control.

According to the present invention, if the car control operation display is
When the display content is for two elements: earthquake control and fire control, the EL1 serving as the light source may be used by cutting the insulating coating 3 shown in FIG. 1 as shown by the dashed line. If the insulating coating 3 is cut and used according to the size of the display window 6 in a similar manner, one EL can be used for display windows of three different sizes.

In this example, the size of the light emitting surface of the EL is L2 vertically and L2 horizontally.
1, and the combination of the light-emitting surface and the insulating film is three vertically, but the size, number, and shape of the ELs are not critical.

〔Effect of the invention〕

According to the present invention, an EL of one size can correspond to display portions of a plurality of sizes. In addition, in the assembly work of display devices, compared to conventional products that fix multiple ELs individually, one
Since it is only necessary to fix one EL, the structure is simple and the assembly time can be shortened. As described above, according to the present invention, only one EL manufacturing mold is required to facilitate mass production and provide an easy and inexpensive EL.
