[Display device]
FIG. 1 is a perspective view showing the appearance of the display device according to the embodiment. The display device 100 includes a display body 10 and a stand 20. The display body 10 is attached to the stand 20. The display body 10 is a display panel in which a plurality of LEDs (Liquid Crystal Display) are arranged. The stand 20 is an assembly-type stand created by assembling a plurality of parts described later.

FIG. 2 shows a state in which the display body 10 is removed from the stand 20. The display body 10 is a foldable panel, and hooks 11a and 11b for hooking on the stand 20 are provided at the upper ends thereof. FIG. 3 shows a state in which the display body 10 is folded. As shown, the display body 10 can be folded along the folding line 12 shown by the broken line. In the example of FIG. 3, the display body 10 is folded into six pieces, and can be miniaturized by folding the display body 10.

FIG. 4 is an exploded view of the stand 20. The stand 20 is roughly divided into a holding frame 21, a base 26, and a cover 32. The holding frame 21 is a member that holds the display body 10, and is composed of an upper frame 22 and a lower frame 23. The upper frame 22 and the lower frame 23 have substantially the same outer size, and the width thereof substantially matches the width of the display body 10. The upper frame 22 and the lower frame 23 are foldably connected by a pair of hinges 24.

The upper frame 22 is composed of a pair of columns 22a and 22b and three beams 22c to 22e vertically connected to the columns 22a and 22b. The beam 22c is provided at the upper end of the upper frame 22, the beam 22d is provided at the lower end of the upper frame 22, and the beam 22e is provided in the middle of the upper frame in the vertical direction. Similarly, the lower frame 23 is composed of a pair of columns 23a and 23b and three beams 23c to 23e vertically connected to the columns 23a and 23b. The beam 23c is provided at the upper end of the lower frame 23, the beam 23d is provided at the lower end of the lower frame 23, and the beam 23e is provided in the middle of the lower frame in the vertical direction.

The upper frame 22 and the lower frame 23 are foldably connected by a pair of hinges 24. FIG. 5 shows a state in which the holding frame 21 is folded. By folding the upper frame 22 to the side where the hinge 24 is provided, the holding frame 21 becomes substantially the same size as the outer size of the upper frame 22 and the lower frame 23. As shown on the right side of FIG. 5, when the holding frame 21 is open, the fixed plate 25 shown by the broken line is indicated by an arrow with respect to the beam 22d at the lower end of the upper frame 22 and the beam 23c at the upper end of the lower frame 23. By screwing in the direction of 71, the upper plate 22 is prevented from falling forward.

Returning to FIG. 4, a pair of claws 29a and 29b are provided on the upper surface of the beam 22c of the upper frame 22. When the display body 10 is attached to the holding frame 21, a pair of hooks 11a and 11b provided at the upper ends of the display body 10 are hooked on the claws 29a and 29b of the upper frame 22. As a result, the upper end of the display body 10 is fixed to the upper end of the upper frame 22. Then, as shown in FIG. 1, a cover 32 that covers the upper end of the display body 10 is attached. The cover 32 protects the upper end of the display body 10.

Further, as shown in FIG. 1, the vicinity of the lower end of the display body 10 is fixed to the holding frame 21 by a pair of fixtures 30a and 30b. Specifically, with the upper end of the display body 10 fixed to the upper end of the upper frame 22 as described above, the U-shaped fixtures 30a and 30b shown in FIG. 4 are attached to the display body 10 and the lower frame. Attach from the left and right so as to sandwich the columns 23a and 23b. Then, as shown by the arrow 72 in FIG. 4, the fixtures 30a and 30b are screwed to the columns 23a and 23b of the lower frame from the back side of the display body 10. In this way, the vicinity of the lower end of the display body 10 is fixed to the holding frame 21. In the above example, the pair of 30a and 30b are attached only to the vicinity of the lower end of the display body 10, but the fixtures 30a and 30b may be attached to the vicinity of the center and the upper end of the display body 10 in the vertical direction. good.

As shown in FIG. 4, four casters 27 are provided on the base 26, and the display device 10 can be moved with the display body 10 attached. Further, the base 26 is provided with a pair of guides 28a and 28b that support the holding frame 21. When the holding frame 21 is attached to the base 26, the support column 23a of the lower frame 23 is housed in the guide 28a, and the support column 23b is housed in the guide 28b. Then, the holding frame 21 is fixed to the base 26 by screwing in the direction of the arrow 73.

FIG. 6 shows the parts of the display device 100 before assembly. The display device 100 includes a display body 10, a holding frame 21, a base 26, fixtures 30a and 30b, and a cover 32. These parts can be stored in the case 40. If a case having casters and handles such as a suitcase is used, it will be easy to move.

When assembling the display device 100, first, as shown in FIG. 5, the upper frame 22 and the lower frame 23 constituting the holding frame 21 are opened and fixed by the fixing plate 25. Next, the columns 23a and 23b of the lower frame 22 are inserted into and fixed to the guides 28a and 28b of the base 26, respectively, and the holding frame 21 is placed in an upright state as shown in FIG. Next, the folded display body 10 is unfolded into a single flat surface, and the hooks 11a and 11b at the upper ends are hooked on the claws 29a and 29b at the upper ends of the upper frame 22 to hold the upper end of the display body 10. It is fixed to the upper end of the above, and the cover 32 is attached on it. Further, a pair of fixtures 30a and 30b are used to fix the vicinity of the lower end of the display body 10 to the holding frame 21. In this way, as shown in FIG. 1, the self-supporting display device 100 is completed. When disassembling the self-supporting display device 100 as shown in FIG. 6, the operation opposite to the above may be performed.
