2. Description of the Related Art As a display device for a building facing the street, there is, for example, one shown in FIG.

This shows an example of the decoration of the roof portion of a gas station. A transillumination sign 52, which displays decorative patterns and characters, is attached to the side edge of the roof 51. Lighting such as fluorescent lamps installed in the building makes it easy to recognize from afar at night and enhances decoration and advertising effects.

By the way, as the sign 52, a hard one made of an acrylic plate or the like has been mainly used.
In recent years, a transparent light-transmitting sheet made of a synthetic resin having flexibility has been used in place of this. FIG. 6 is a plan view showing the outline of the signboard structure. A U-shaped signboard frame 53 surrounding the roof part covers the open part formed from the front surface to the side surface of the transmitted light sheet 54. It is covered with.

Although the transmitted light sheet 54 has flexibility, it is fixed in a state in which a certain amount of tension is applied by its end clamps, so that it has a neat flat appearance.

The signboard frame 53 has a built-in illuminating means L such as a fluorescent lamp so as to be located behind the transmitted light sheet 54.
The patterns and characters printed on No. 4 are made to stand out clearly.

[0007]

However, in such a conventional display device, since the transmitted light sheet 54 has a flexible structure, a decoration such as a three-dimensional character projected on the transmitted light sheet 54 is projected. There was a problem that it was difficult to attach the body.

It is an object of the present invention to provide a display device having a decorative body protruding from a transmitted light sheet, focusing on the above problems.

[0009]

According to the present invention, there is provided an opening portion formed in a signboard frame, a transparent light sheet which has flexibility and covers the opening portion, and is located behind the transparent light sheet. In a display device including a first illuminating means built in a signboard frame, a decorative body formed three-dimensionally from a material having transmissivity, a second illuminating means for illuminating the decorative body from behind, and a decorative body. A support plate positioned behind the transmissive light sheet and joined to the back surface of the transmissive light sheet, a fastening member that joins the decorative body and the support plate with the transmissive light sheet sandwiched therebetween, and the support plate and the signboard arranged so as to be orthogonal to the transmissive light sheet. And a column for connecting the frame.

According to the second aspect of the present invention, the support plate is formed of a transparent material, and the transmitted light from the first illuminating means is used as the second illuminating means.

[0011]

The transmitted light sheet is illuminated from the inside by the first illuminating means, while the decorative body is illuminated from the inside by the second illuminating means, so that a sufficient amount of light is secured in each case and the decorative body is transmitted. The light that has passed through the light sheet is also illuminated from the outside so that it stands out clearly.

By arranging the pillars provided in the signboard frame at right angles to the transmitted light sheet, it is possible to suppress the shadow of the pillars from being reflected on the transmitted light sheet, and it is possible to reduce uneven illumination on the transmitted light sheet.

The ornamental body is cantilevered by the fastening means to the support plate via the transmitted light sheet and the cantilevered frame via a plurality of columns.
Since it is supported by the tension of the transmitted light sheet, sufficient support strength is secured.

Since the decorative body is fixed to the transmitted light sheet in a state in which a tension force is applied, it is possible to prevent the occurrence of slack or the like due to the mounting of the decorative body, because the decorative body is formed in a clean appearance.
