It is formed in the portions 4b and 4b.

Next, the operation of the electronic signboard device 1 of the embodiment thus configured will be described. When installing the electronic signboard device 1 in the folded state shown in FIG. 3 at the road construction site, first, the lower columns 3a, 3a of the pair of left and right bending link columns 3, 3 are placed around the pivot pins 6, 6. Rotate upward, and in this state, insert bolts 12 and 13 as connecting pins into the connecting pin holes 9a and 9b of the lower connecting brackets 9 and 9, respectively, and insert these into the short side members 2b and 2b of the base frame 2. The screw holes 2c and 2c and the bending link support columns 3 and 3 are screwed into the screw holes 3c and 3c of the lower support columns 3a and 3a, respectively. By doing so, the pair of left and right lower columns 3a is held in a standing state in which the lower columns 3a are tilted backward at an angle of approximately 55 degrees.

Subsequently, the upper columns 3b, 3b of the pair of left and right bending link columns 3, 3 are rotated upward around the pivot pins 7, 7, and in this state, the bolts 14, 15 as connecting pins are connected. The connecting pin holes 10a and 10b of the intermediate connecting brackets 10 and 10 are respectively inserted, and these are screwed into the bending columns 3 and 3 of the lower column 3a and the screw holes 3e and 3e of the upper column 3b, respectively. By doing so, the pair of left and right upper columns 3b, 3b are held in a standing state in which they are tilted forward at an angle of approximately 55 degrees.

Therefore, the main body 4 of the electronic sign board is rotated around the pivot pins 8, 8 to stand upright, and in this state, the bolts 16, 17 as connecting pins are connected to the upper connecting brackets 11, 11. The pin holes 11a and 11b are inserted into the pin holes 11a and 11b, respectively, and these are inserted into the screw holes 3f and 3f of the upper columns 3b and 3b of the bending link columns 3 and 3, and the screw holes 4c and 4c of the left and right side portions 4b and 4b of the main body 4 of the electronic sign board. Screw each into 4c. By doing so, the electromotive marking plate body 4 is supported on the upper portions of the refraction link struts 3 and 3 in a substantially upright state as shown in FIG.

In this way, at the road construction site, the electric indicator board body 4 supported in a substantially upright state on the base frame 2 via the pair of left and right bending link struts 3 and 3 has a built-in light bulb. The signboard 4a's sign is illuminated by the light, and necessary signs such as what should be slowed down and one side should be visible during road construction are visible to vehicles and pedestrians even at night. Mark.

When the road marking work is completed and the electric sign board device 1 is to be removed from the road construction site, the bolts 12 to 17 are pulled out in the procedure opposite to the above. By doing so, the electronic indicator board body 4 becomes rotatable around the pivot pins 8 and 8 with respect to the upper columns 3b and 3b of the bending link columns 3 and 3, and the bending link columns 3 and 3 are The lower support columns 3a, 3a and the upper support columns 3b, 3b are rotatable relative to each other around the pivot pins 7, 7, and further, the lower support columns 3a, 3a of the bending link support columns 3, 3 are fixed to the base frame 2. The short side members 2b, 2b on both the left and right sides are rotatable about the pivot pins 6,6.

Therefore, as shown in FIG. 3, the pair of left and right refracting link struts 3 and 3 are refracted along the short side members 2b on both the left and right sides of the base frame 2 so that the electronic indicator board body 4 is moved to the base frame 2. Fold to polymerize on top. By doing so, the electronic signboard devices 1 can be transported and stored in a space-efficient state by stacking a plurality of them or arranging them side by side. Although not shown, by providing casters or the like on the left side end surface of the short side member 2b of the base frame 2 in FIG. 3 or on this end surface and the left side end surface of the sign board body 4, the caster shown in FIG. By further erecting the folded device of the present invention by grounding the provided casters and the like, it becomes possible to store and carry the space more efficiently.
