Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a large-sized video display device used as a medium for text information or video information.

Structure of conventional example and its problems As shown in FIGS. 1 and 2, a conventional large-sized video display device includes a display section 2 on the front side of a main body section 1, and a light source held within the main body section 1. 3, the display unit 4 held in front of the display section 2 is irradiated. One side of the display section 2 is rotatably attached to one side of the main body section 1 by a hinge 5, and connection pieces 6 and 7 attached to the other side of the display section 2 and the other side of the main body section 1 are connected by screws 8. are connected to each other and fixed to the main body part 1. When performing maintenance or adjustment, for example, replacing the light source 3, in such a large-sized video display device, the display section 2 needs to be opened to the main body section 1. In the conventional large image display device described above, the display section 1 is rotatably connected to the main body section 2 by a hinge 5, and since the device itself is large, it is difficult to connect the display section 1 to the main body section 2. However, when opened, a large maintenance space S was required, and installation facilities and locations were restricted. Furthermore, as mentioned above, since the display section 1 is large and heavy, the hinge 5
There were disadvantages such as a large moment acting on the steel, which caused problems in terms of strength.

Purpose of the Invention The present invention eliminates the drawbacks of the above-mentioned conventional examples, and can reduce the space for maintenance and adjustment to the minimum necessary, improve the strength, and further improve the installation It is an object of the present invention to provide a large-sized video display device that can expand the room for selection of locations.

Configuration of the Invention In order to achieve the above object, the present invention includes a main body,
a guide rail that is rotatably supported by the main body; a support member that is removably connected to the guide rail and supports the guide rail in the horizontal direction; and a display unit that is removably attached to the main body. , the display section is equipped with a guide roller that moves along a horizontally supported guide rail to move the display section parallel to the main body section.

DESCRIPTION OF EMBODIMENTS Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 3, reference numeral 11 indicates a main body portion, and 12 a display portion provided on the front side of the main body portion 11. A light source 13 is held in the main body part 11 and can illuminate a display unit 14 held in front of the display part 12. In the main body part 11, a guide rail 17 made of channel material is rotatably supported by a pin 18 on an upper support plate 16a between support members 16, 16 provided between frame-shaped protrusions 15 on the upper and lower sides. ing. A stopper 19 is attached to the upper surface of the tip of the guide rail 17, and a rotating handle 20 is attached to this stopper 19. At the bottom of the support member 16, the base of an arm 21 is rotatably supported by a pin 22 via a spacer (not shown), and a handle 23 for rotation is attached to the tip of the arm 21. . Therefore, guide rail 1
The guide rail 17 can be fixedly held in the horizontal direction by raising the arm 21 horizontally, raising the arm 21 diagonally, and connecting the ends of both with a bolt 24 with a spacer 21a interposed therebetween.
One or more guide rollers 25 are rotatably supported on a support plate 12a on the side surface of the display section 12, and the upper part of a connecting plate 26 is removably fixed to this shaft with a bolt 27. One or more guide rollers 28 are rotatably supported at the lower part of the connecting plate 26, and these guide rollers 25, 28
The upper and lower sides of the guide rail 17 held in a horizontal state are held between the guide rail 17 and the guide roller 25.
Prevents it from falling off. A handle 29 is attached to the center of the connecting plate 26, so that the handle 29
9 causes the guide rollers 25 and 27 to roll along the guide rail 17, and the display section 12 is moved to the main body section 1.
It can be moved toward or away from 1. A fixing metal fitting 30 is attached to the side surface of the display part 12 on the side of the main body part 11, and the fixing metal fitting 30 is fixed to the support member 16 of the main body part 11 with bolts 31 while the display part 12 is stacked on the front surface of the main body part 11. be able to. A cover 32 is connected to the side of the main body part 11 so as to be openable and closable by a hinge 33, and covers the guide rail 17 with the guide rail 17 hanging down and the arm 21 standing up on the outside thereof.
Or it can be exposed. This cover 3
2 is removably attached to the protrusion 15 of the main body 11 by appropriate means while covering the guide rail 17, arm 21, etc.

Next, the operation of the above embodiment will be explained. When performing maintenance or adjustment, for example, when replacing the light source 13, the cover 32 is first rotated outward via the hinge 33 to open the sides of the main body 11 and the display section. Next, the guide rail 17 is raised horizontally from the main body 11 using the handle 20. Next, pull out the arm 21 diagonally forward from the main body 11 using the handle 23,
The guide rail 17 is fixed with bolts 24, and the guide rail 17 is fixed in a horizontal state. Next, the connecting plate 26 is fixed to the shaft supporting the guide roller 25 with bolts 27, and the upper and lower portions of the guide rail 17 are sandwiched between the guide rollers 25 and 28. After that, bolt 31
Remove the display section 12 fixing fittings 30 from the main body section 1.
1, the display unit 12 is moved along the guide rail 17 by operating the handle 29 and rolling the guide rollers 25 and 28, and the support member 11
A maintenance and adjustment space S can be formed by separating the parts parallel to each other. Thus, the space between the main body section 11 and the display section 12 can be used to replace the light source 13. When the work is completed, the guide rollers 25 and 28 are first rolled along the guide rail 17, the display section 12 is moved and stored toward the main body section 11, and the fixing fittings 30 are fixed to the main body section 11 with the bolts 31.
Fixed to. Next, remove the bolt 27 and connect the connecting plate 26.
Then, by removing the bolt 24, the guide rail 17 is lowered, and the arm 21 is raised.
Thereafter, the cover 32 can be rotated inward via the hinge 33 to cover the guide rail 17, arm 21, etc.

Note that the large-sized video display device of the present invention is
It can be implemented in any installation method, such as stationary or wall-mounted.

Effects of the Invention As is clear from the above description, according to the present invention, the display section is moved in parallel to provide a spacer for maintenance and adjustment between the display section and the main body section. can. Furthermore, the weight of the moving part can be held by the guide rail and its support member, resulting in increased strength. Furthermore, as mentioned above, maintenance and adjustment space can be kept to the minimum necessary, so any installation method such as hanging, sliding, wall-mounting, etc. can be adopted.
Therefore, there are advantages such as being able to expand the selection of installation locations.
