DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internally illuminated signboard, and when illuminated at night, the entire internally illuminated signboard shines uniformly with a minimum of fluorescent lights, and is sufficiently noticeable.
Moreover, the present invention is aimed at an internally illuminated signboard that is lightweight, simple in structure, easy to manufacture, and ultimately inexpensive.

[0002]

2. Description of the Related Art A conventional interior illuminated signboard 1 incorporating a plurality of fluorescent lamps 31 has a lower surface 12A, a left side surface 12B, and an upper surface 12C as shown in FIG.
And a metal frame 12 made of iron or an iron alloy or aluminum or an aluminum alloy, which comprises a right side surface 12D and a support 12E, and a plastic front surface 13 and a rear surface 14 which are vertically oriented and display advertising contents, A plurality of light sources 31 such as fluorescent lamps 31 are provided inside.

In this case, the length D of the exterior signboard is limited by the frame because of the strength of the entire interior illuminated signboard 1 and the difficulty of molding the front and rear faces 13 and 14 from plastic plates. It was thought that the value was about 1 to 1.4 times the length of the width E. That is, the size of the frame width E of the frame 12 was considerably larger than the size of the rising portions 13B and 14B (described in FIG. 16) of the front surface 13 and the rear surface 14.
In this case, the rising portions 13B and 14 of the front surface 13 and the rear surface 14 are provided.
The dimension of B was a value of about 30 mm at the maximum.

[0004] Further, as shown in the front view of the conventional internally illuminated signboard shown in FIG. 15, a plurality of fluorescent lamps 31 disposed inside the internally illuminated signboard 1 are arranged at both ends of the fluorescent lamp 31. The lower surface 12A and the upper surface 12C of the frame 12 are provided via the holder 32 provided.
It was only arranged in parallel with.

[0005] As shown in a plan view of a conventional internally illuminated signboard shown in FIG.
The cross section composed of BA and the rising portions 12BB and 12BC has a substantially concave shape, and the lower surface 12A, the upper surface 12C, and the right side surface 12D of the frame 12 are not clearly shown in the drawing, but are the same. It has a simple structure. Also, the front 13
Consists of a plane 13A, a rising portion 13B and a flange 13C,
The rear surface 14 has a similar structure.

By inserting the flanges 13C and 14C of the front surface 13 and the rear surface 14 of such a structure into a frame 12 having a substantially concave cross section and being formed in a ring shape,
As shown in FIGS. 14 and 16, a space surrounded by a frame 12, a front surface 13, and a rear surface 14 including a lower surface 12A, a left side surface 12B, an upper surface 12C, and a right side surface 12D is created. Was composed.

[0007]

However, such a conventional internally illuminated signboard 1 has the following problems. First, the wide frame 12 made of metal has a large overall weight due to the width, so that the structure has to be strengthened and the manufacturing cost is expensive. On the other hand, if the frame 12 is made of plastic in order to make the entire structure lightweight and to simplify the structure, the strength is weak. In this case, the strength was weak in spite of considering not only the frame 12 but also the whole plastic.

If the signboard has a complicated shape such as a tree or a doll as shown in FIG. 2, the metal frame 12 should be manufactured according to the complicated shape. Is
If it is a large amount, it is possible to make a mold and make it,
In the case of medium or small quantities, it is handmade in terms of production cost, and in that regard, production took time, and finally the production cost became high.

[0009]

According to the present invention, a light source 3 is provided inside.
1, the flat portion 62A of the plastic main body 62 constituting the interior illuminated signboard 60
And a flat portion 63A of a plastic main body 63 is back-to-back, and a strength portion 60B is formed by joining a back-to-back mating surface 60A with a joining means, and further, the light source is attached to the strength portion 60B. 31
A hole 60C for arranging is provided. Further, a strength member 66 is provided between the strength portions 60B, and the strength member 66 is made of metal. And the strength portion 6
0B is characterized in that it is disposed at the center of the internally illuminated signboard 60. Further, the main body A 62 and the main body B 63 are characterized in that their cross-sections have a substantially concave shape. , The flat portion 62A of the main body 62 and the main body 6
3 is characterized in that a part of the flat portion 63A is a surface having irregularities, and further, the joining means is characterized by using an adhesive, and further comprises the internally illuminated signboard 60. The interior of the main body 62 and the interior of the main body 63, or the interior of the main body 62 forming the internally illuminated signboard 60, is easily reflected.
