Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an EL display device used for route guidance and the like.

[Conventional technology]

The EL element has applications as a display sheet by taking advantage of its flexibility and thinness. For example, in order to guide the way to a temporary event venue, a display sheet with an arrow or the like is attached to a pillar or wall along the route, or a sign (yellow and black) that indicates a dangerous place for a required period is displayed. It is often affixed to a pillar or the like near a specific place as a striped pattern). In that case, it is convenient to use an EL display sheet as the display sheet because the display can be clearly displayed and the appearance is good.

Conventionally, a double-sided adhesive tape is attached to the back surface of the EL display sheet 1 as shown in FIG. 4, or a transparent adhesive tape is used to fix it to a target position, for example, the surface of the pillar A.

[Problems to be solved by the invention] However, this kind of display sheet is removed at the end of the event or the danger is removed and used at other places,
It is stored temporarily, and if it is attached with a double-sided adhesive tape or the like, it is not easy to remove it, and it is difficult to replace the EL cell.

An object of the present invention is to provide an EL display device in which attachment / detachment and EL cell replacement at desired locations are easy.

[Means for Solving the Problems]

The present invention has a flexible EL display sheet for displaying arrows and the like, a surface plate using a flexible thin transparent plastic sheet, spacers fixed to both end portions of the surface plate, and a two-divided space required in the center. A flexible back plate that is stacked and fixed on the spacer so that a plurality of eyelets are provided on the fixing parts on both sides of the both plates, and the space between the plates is provided in the storage part of the EL display sheet. It is characterized in that it is provided with a case, and is fixed to the installation location by using a cord or an auxiliary case.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is an EL display sheet and 2 is a case. This case 2 is made of a flexible thin transparent plastic sheet (for example, a thickness of 0.5).
mm vinyl chloride sheet) as the surface plate 2A,
Spacers 2B having substantially the same thickness as the EL display sheet 1 are fixed to both side portions of the front surface plate 2A, and a flexible back surface plate 2C divided into two is stacked on the spacers 2B so that a gap g is formed in the central portion. Since it is fixed, a plurality of eyelets 2D for attachment are provided on the fixing portions on both sides.

The EL display device having the above structure is used by inserting the EL display sheet 1 into the case 2. When the installation location is a column A as shown in FIG. 2, the string 3 is passed through the eyelet 2D of the case 2 and tightly bound and fixed to the column A. In this case, since there is a gap g in the central portion of the back surface of the case 2, the difference in curvature between the front and back is absorbed and a close contact is achieved. Moreover, the eyelet 2D increases the strength of the hole portion, and it is possible to bind the hole portion with a sufficient force, so that the hole portion is securely fixed.

If the installation location is flat like a wall surface,
As shown in the figure, the auxiliary case 4 in which most of one surface of the book case is cut out (or made transparent) is used, and the auxiliary case 4 is attached to the installation location with double-sided adhesive tape or the like.
The case 2 in which the EL display sheet 1 is inserted is inserted.

If a UV cut sheet (for example, Panlite manufactured by Teijin Kasei) is used for the surface plate 2A, it is effective for improving the weather resistance of the EL cell.

[Effect of device]

As described above, according to the present invention, the back plate of the case is divided into two, and a gap is provided in the center thereof, so that it is possible to absorb the difference in curvature between the front and back when it is formed into a curved surface. Can be securely fixed to the place in close contact. Moreover, it is easy to insert a long EL display sheet by dividing the back surface into two parts. Further, since the eyelets are provided on both sides of the case, the strength of the hole portion is increased, and it becomes possible to apply a sufficient force at the time of fixing. Further, since the EL display sheet is housed in the case and fixed by the cord or the auxiliary case, the EL display sheet can be easily attached and detached without causing damage to the device body.
