FIG. 1 to FIG. 3 show a large-sized display body. This large-sized display body is fixed, for example, so that two columns 1 protrude from a frame 2 from both sides of the column 1. The frame 2
The display plate 3 is attached to the front opening and the back plate 4 is attached to the back opening.

The cross section of the column 1 is formed in a letter shape or a convex shape.

The frame 2 is formed in a rectangular shape by upper and lower frame members 2a and 2b and both side frame members 2c, and a storage recess 5 for storing the frame material 3a of the display panel 3 is formed in the front opening. On the inner peripheral edge of the back side opening, an engaging protruding edge 6a is formed on an engaging edge 6 for receiving a back plate 4 described later. Each of the frame members 2a, 2b, and 2c is formed to have a concave cross section, and a convex member 7 is fixed inside the side frame member 2c. A wiring cord 8 is housed inside the convex member 7, and a socket 9 for mounting a light source (fluorescent lamp) 21 and a glow lamp (not shown) are mounted outside.
A convex member 7 is also fixed inside the lower frame 2, and a stabilizer 10 is fixed to the convex member 7. The column 1 is fixed to the frame 2 with bolts and nuts 11.

The back plate 4 is divided into three parts around a portion fixed to the column 1. As shown in FIGS. 2 to 7, a reinforcing rim 12 is fixed by rivets 13 on the back surface of the entire peripheral edge of each of the divided plates 4a, 4b, 4c to form a unit.
Have been. The reinforcing edge member 12 is disposed in upper and lower portions and both side portions, the edge 14 of the dividing plane is fixed so as not protrude is Enzai 1 2. The other edge member 12 includes a mounting edge 12 a fixed to the back surface of the back plate 4 with screws and rivets 13, and a cross section L formed at an end of the mounting edge 12 a.
The guide edge 12b and the reinforcing edge 12c are formed in a Z-shaped cross section. An engaging edge 15 is formed inside the mounting edge 12a, and a corner tool is provided in a groove of the engaging edge 15.

Next, the display plate 3 is formed by sandwiching a display means 17 such as a film between a pair of translucent plates 16 such as an acrylic plate and a glass plate framed by a frame material 12. The display plate 3 is housed inside the outer opening of the frame 2,
It is fixed by appropriate means.

By the way, when assembling the large-sized display having the above structure, first, the frame 2 is attached to the support 1 by the bolts and nuts 11.
And fix it. Similarly, the reinforcing edge member 12 is fixed to the back surface of the peripheral portion of each of the divided plates 4a, 4b, 4c. At this time, the engaging edge 15 of the reinforcing rim 12 is engaged with the end face of the back plate 4 to determine the mounting position of the reinforcing rim 12, and in this state, the mounting rim 12a is divided into the dividing plates 4a, 4b, 4
The rivet 13 is fixed to the peripheral portion of c. The above assembly may be performed in advance in a panel unit configuration in which the back plate 4 and the reinforcing edge member 12 are in sliding contact with each other.

Next, the column 1 is fixed to a wall at a site where a building, a passage or the like is mounted, or is mounted on a column. Then, as shown in FIG. 4, one split plate 4a is inserted into the inside from the front opening of the frame 2, and the edge corresponding to the frame 2 is engaged with the inside of the engaging projection 6a of the back opening. Combine. This determines the position of the dividing plate 4a.
As shown in FIG. 3, the reinforcing edge 12 of the split plate 4 a is fixed to the edge 6 of the opening on the back side of the frame 2 with rivets 13. further,
The edge corresponding to the column 1 of the divided plate 4a is fixed to the column 1 and the separately formed reinforcing edge member 12 with bolts and nuts 18. Similarly, the other divided plates 4b and 4c are fixed, and the support columns are butted and connected to each other to form the back plate 4 as shown in FIG. Then, attach the light source 21 in the socket 9 as shown in FIG. Further, as shown in FIG. 7, after the display plate 3 in which the display means (17) is sandwiched between a pair of light-transmitting plates (16) framed by the frame material 3a is stored in the storage recess 5 in the frame material 3a, It is fixed so that it can be opened and closed by appropriate means.

As described above, since the back plate 4 is divided and the divided plates 4a, 4b, 4c with the reinforcing edge members 12 are attached to the frame 2 to be integrated, the respective divided plates 4a, 4b, 4
c is reinforced and can be inserted into the front opening of the frame body 2 from the front opening and fixed to the rear opening.
On the other hand, when the back plate 4 has an integral structure as in the related art,
Since the front opening is smaller than the back plate 4, it cannot be inserted inside. Therefore, it is particularly effective when replacing the back plate 4 of the existing large display body.

Further, since the reinforcing edge member 12 is fixed to the periphery of the divided plates 4a, 4b, 4c of the back plate 4, the divided plates 4a, 4b, 4c are hardly bent. Therefore, as a result of the division, the assembly work can be performed by one person in combination with the reduction in weight, and labor saving can be achieved.

The reinforcing edge 12 is not limited to the above-described example. For example, as shown in FIG. 8, the frame members 2a, 2b, 2c
May be superimposed on the reinforcing edge material 12 and the back plate 4 (divided plates 4a, 4b, 4c) and connected by rivets 13.

Further, as shown in FIG. 9, a reflecting plate (aluminum specular alumite, stainless steel, etc.) 20 for reflecting light from a light source may be attached to the back plate 4, and in this case, as shown in FIG. The plate 20 is also divided plate 4a, 4
b, 4c, and may be riveted in the same manner as the reinforcing edge member 12, and fixed to the frame 2 together with the divided plates 4a, 4b, 4c. By attaching the reflection plate 20, unevenness in irradiation from the light source is eliminated, and the display effect is improved.

[0020]

According to the present invention, since the back plate is divided and the divided plate with the reinforcing rim is attached to the frame and the column , each divided plate is reinforced, and the conventional back plate has an integral structure. In this case, the front side opening was smaller than the back plate and could not be inserted inside. However, the frame body can be securely inserted into the inside from the front side opening and fixed to the back side opening.
Therefore, it is effective especially when replacing the back plate of the existing large display body. Also, connect the split plates so that they are flat.
Since it is fixed, the reflection of light from the light source is disturbed.
I do not.

Further, since the reinforcing edge member is fixed to the peripheral portion of the divided plate of the back plate, each divided plate is hardly bent. Therefore, the strength of the display body is increased, and labor such as mounting can be saved.
