FIG. 9 is a plan view corresponding to FIG. 8 shown in the related art.

FIGS. 1, 2, 3 and 4 are different from FIGS. 6, 7, 8 and 9 shown in the prior art in that the structure of the box and the lid frame is different from that of the prior art. Extruded material is used. The hanging structure of the box, the heat radiating plate, and the internal electric equipment are the same as in the conventional case, and are omitted.

That is, the ceiling plate 1A and the bottom plate 1B of the box body
And the side plates 2A and 2B are manufactured from the same extruded die, and FIG.
As shown in FIG. 3B and the longitudinal sectional view of FIG. 3, the upper, lower, left and right are symmetrical.

The box body is formed by welding the ceiling plate 1A and the bottom plate 1B and the butted portions of the side plates 2A and 2B on both sides. Among them, the side plates 2A and 2B are previously bent into an arc shape by three rolls as shown in FIG.

On the ceiling plate 1A and the bottom plate 1B, a radiator plate 5, which is almost the same as the radiator plate 15 shown in FIG.
As shown in FIG. 3A and FIG. 3, the upper and lower ends are welded to the ceiling plate 1A and the bottom plate 1B, respectively. A lid (not shown) that covers the upper part of the heat sink 5 is attached to the ceiling plate 1A in the same manner as in the conventional FIGS.

As shown in FIG. 1A, a pair of support holes 1a are symmetrically formed in the ceiling plate 1A.
The box body is suspended in the same manner as in the related art via a mounting plate at the lower end of the support tube which is fixed to the fixing hole around the base with bolts.

Hereinafter, each component will be described in detail. Ceiling board 1
A and the bottom plate 1B are the same product except for the support hole 1a, and the left and right side plates 2A and 2B are also the same product and have the same width. A pair of substantially L-shaped first ribs 10A shown in FIG. 3 are provided on the inner surfaces of the ceiling plate 1A, the bottom plate 1B and the side plates 2A and 2B.
Are symmetrically protruded by the extrusion die.

Outside the first ribs 10A, L-shaped second ribs 10B, which are lower in height than the first ribs 10A, are symmetrically protruded, and further outside the second ribs 10B. Is
A third rib 10C having a T-shaped cross section protrudes symmetrically. Further outside the third rib 10C, the third rib 10C is provided.
Fourth rib 10D, fifth rib 10E and sixth rib 10 having the same shape as C.
F are projected in order at intervals.

The ceiling plate 1A, the bottom plate 1B and the side plates 2A, 2B
In the opening side of FIG. 3, a U-shaped edge 9 opened to the outer surface side is shown in FIG.
As shown in FIG. These edges 9
As shown in FIG. 4 and FIG. 5 showing a partially enlarged view of FIG. 4, a chloroprene rubber material having a substantially Ω-shaped cross section is formed in the shallow groove formed on the outer surface side on the base end side of FIG. The base of the waterproof packing 8 is attached and joined with an adhesive.

In FIGS. 4 and 5, on the other side of the hinge 6, one side of which is fixed to the opening side of the ceiling plate 1A, is formed by welding from an extruded aluminum material into a frame shape in a front view (not shown). The base end of the upper end of the lid frame 3 is supported by a plurality of bolts. Although the opening sides of the bottom plate 1B and the side plates 2A and 2B are not shown, they have the same cross-sectional structure except for the hinge 6 because they are made of the same extruded material.

On the inner surface side of the lid frame 3, L-shaped convex portions 3a and 3b are formed in order, and a convex portion 3c formed in a substantially convex shape is formed on the outer side of the convex portion 3b. Are formed.

As a result, a concave portion 3d having a rectangular cross section is formed between the convex portions 3a and 3b on the base end side, and substantially cross-shaped concave portions 3e and 3f are formed between the convex portions 3b and 3c and outside the convex portion 3c. Is formed.

The convex portion of the rubber cushion 7 having a substantially L-shaped cross section is press-fitted into the front concave portion 3f. The acute angle portion formed at the front end of the lid frame 3 is formed into an arc-shaped curved surface by an extrusion die, and a substantially arrow-shaped hollow portion 3g is formed inside the curved surface portion.

On the inner peripheral side of the lid frame 3, a convex portion 3h slightly protruding toward the box side is formed, and the outer surface side of the screen 4 is attached to the box side of the convex portion 3h. The screen 4 is pressed from the back surface on the outer surface side of the rubber cushion 7 inserted on the back surface side.

In the guide display device thus configured, the ceiling plate 1A, the bottom plate 1B, and the left and right side plates 2A, 2B.
And ribs 10A, 10B, 10C formed on the inner surface side of the lid frame 3.
Since 10D, 10E, 10F and the convex portions 3a, 3b, 3c increase the surface area of the inner surface of the box, it is possible to increase the heat absorption rate of the internal air whose temperature has increased. The amount of heat transmitted to the air can be increased.

Therefore, the internal air can be further cooled by the ribs and the projections in addition to the heat radiating plate provided in the conventional guide display device, so that the temperature rise of the internal electric appliances can be suppressed.

When the screen 4 expands due to an increase in internal temperature, the screen cushion 4 can be prevented from bending due to the bending of the rubber cushion 7, so that the characters displayed by the LED display unit due to the bending are distorted. This can prevent the phenomenon that can be seen with.

A substantially cross-shaped concave portion 3e formed in the intermediate portion on the inner surface side of the lid frame 3 holds the lid frame 3 together with the screen 4 with respect to the left and right sides of the lid frame 3 during maintenance and inspection. It can be used as an insertion hole for a nut for tightening a fastener for fixing one side of the stopper to be maintained.

On the other hand, the ribs 10A to 10F can increase the rigidity of the box together with the heat radiating plate 5, thereby preventing the box from being distorted during transportation or installation work. The screen can be prevented from being displaced. Further, the left and right side plates 2A and 2B are formed in an arc shape,
Since the end of the lid frame 3 is formed as a curved surface, the design of the appearance can be improved.

[0044]

As described above, according to the first aspect of the present invention, the door for holding the outer periphery of the screen is provided on the opening side of the rectangular box frame via the hinge, and the light emitting display panel is provided on the inner side of the screen. In the guide display device accommodating the electric appliance for driving the light emitting display panel, a plurality of uneven portions are formed on the inner periphery of the box frame. By forming a bulging part at the end of the box, the heat transfer coefficient from the air inside the box to the box was increased, and the temperature rise of the air and the electrical equipment inside was suppressed. A guide display device capable of maintaining the characteristics of the internal electric appliance without preventing the display accuracy from being lowered can be obtained.

Further, according to the invention corresponding to claim 3, the both side plates of the box frame are formed in an arc shape whose central portion protrudes outward, and further according to the invention corresponding to claim 4, The door is made of light alloy extruded material, and the outer edge of the screen on the screen side has an arc-shaped cross-section, which enhances the design of the exterior of the box. Maintain the characteristics of electric appliances, prevent the display accuracy from lowering,
It is possible to obtain a guidance display device that can improve the design.
