BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display board assembly used in the field of construction work, road works and the like.

[0002]

2. Description of the Related Art A display board is used to clearly indicate a prohibited area when road construction is performed. Since such a display board must be movable as required, it is required that it can be freely assembled and disassembled and is easy for transportation.

For example, a display device conventionally used in road construction and the like is as described in Japanese Utility Model Publication No. 62-7687, which is shown in FIG. This has a structure in which two horizontal bars 11 are assembled between two barricade support legs 10 and a protective net 12 which also serves as a display plate is assembled between the horizontal bars 11. Although it is sometimes effective to use such a conventional barricade as a display board, it is not always convenient when only a display device is required. That is, the display board has too many parts,
Moreover, the disassembly and assembly thereof was inconvenient. Further, the display device which is also used as the barricade has not always been good in appearance.

An improved version of this is shown in FIG. This is a conventionally used unit type display device. This display device has a configuration in which a display plate 14 is sandwiched between the tops of two inverted V-shaped barricade support legs 13. With such a structure, the display plate 14 and the barricade support leg 1
It was unstable and easy to fall because it was connected to 3 at only one place. Further, the barricade support legs 13 were preformed and were extremely bulky during handling and storage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 3 shows a display plate 16 of the present invention sandwiched between two display plate support legs 15 of the present invention. FIG.
In the above, the display board 16 of the present invention is inclined with respect to the ground on which the display board support leg 15 is installed. FIG. 4 is an assembly of the same parts as in FIG. 3, as viewed from the back side of the display board 16, and therefore the word “under construction” seen in FIG. 3 cannot be seen. The display board 16 is perpendicular to the ground.
A detailed perspective view of the display panel 16 of the present invention is shown in FIG. The display board 16 of the present invention has a frame 17 having a rectangular frame structure, two upper support pipes 18 and two lower support pipes 18 fixed to the side surfaces of the frame 17. The upper and lower parts refer to the ground. The support pipe 18 is formed of a pipe in this embodiment. The length of the support pipe 18 is about the width of the display plate support leg 15 shown in FIG. Two pieces are arranged on one side surface of the frame 17 and two pieces are arranged at substantially the same position on the other side surface opposite to the side surface. Around the rectangular frame of the frame 17, a section of road construction is clearly indicated, and a display plate 19 indicating the direction is attached and adhered. In FIG. 5, the dotted line in the display plate 19 represents the portion of the frame 17, and in this embodiment, the display plate 19 and the frame 17 are formed by adhesion.

Next, referring to FIGS. 6, 8 and 10, the display plate support leg 15 will be described. The leg 20 is formed of an elongated member having a U-shaped cross section. A gripping tool 26 is attached to one end of the leg 20 so as to clamp the upper support pipe 18 of the display board 16 of the present invention. The two grippers 26 are pivotally supported by the shaft pin 21. Therefore, each leg 20 can be opened and closed around the shaft pin 21 (FIG. 8). A leg connector 23 is attached to the leg 20 at a position of about 1/3 of the entire length of the leg 20 on the side opposite to the grip 26 via a support pin 24. One end of the leg connector 23 has a support pin 2
4 and the other end is rotatably supported by the leg 20 and the shaft pin 25, respectively. The mounting end of the support pin 24 of the leg connector 23 is formed with a recess 31 so that the lower support pipe 18 of the display plate 16 of the present invention can be clamped between the leg 20 and the leg connector 23. . Also, on the side of the shaft pin 25, a recessed portion 30 is formed on the lower side thereof so as to sandwich the support pipe 18 between the leg couplings 23.

The display plate supporting leg 15 of the present invention can be closed around the shaft pin 21 as shown in FIG.
At this time, similarly, the two leg connecting tools 23 are also closed around the shaft pin 25. The leg connector 23 is formed of a “U” -shaped member, but the “U” -shaped member of the leg connector 23 is used for the leg 20.
Is inserted inside the "U" shaped member. In Figure 7,
The upper support pipe 18 of the display plate 16 of the present invention is attached to the grip 26.
And the lower support pipe 18 is sandwiched by the lower recesses 30 formed between the leg connectors 23. In FIG. 7, since the display plate supporting leg 15 of the present invention acts on its own by its own weight, and also the leg connector 23 also acts on its own, the leg connector 23 is a lower support pipe. It acts to push 18 towards the ground. Therefore, it is not necessary for the recess formed by the leg connecting members 23 and the lower support pipe 18 to be naturally engaged with each other to exert any force.

Next, FIG. 9 shows a state in which the display plate 16 of the present invention is obliquely sandwiched between the display plate support legs 15 of the present invention. In this case as well, the lower support pipe 18 is similarly sandwiched by the recess 31 formed by the leg connector 23 and the leg 20. The lower support pipe 18 can be naturally held in the recess 31 formed between the leg connector 23 and the leg 20 so that the lower support pipe 18 can be freely actuated by its own weight.

In this assembled state, the structure of the present invention is
It should be noted that the configuration shown in FIG. 1 which is the conventional technique is completely different. In the conventional configuration shown in FIG. 1, the lower horizontal bar 11 is the shaft pin 2 between the leg connectors 23 corresponding to the present invention.
5 is arranged in the recess formed in the upper part. On the other hand, in the present invention, the lower support pipe 18 has a recess 30 (or a recess 31 between the leg 20 and the leg connector 23) formed on the lower side of the shaft pin 25 between the leg connectors 23. ) Is located. See Figures 4 and 7 for this.
Such a difference in structure is that the upper horizontal bar 1 is different in the conventional structure.
This is because 1 and the lower horizontal bar 11 are separate, while in the present invention, the upper support pipe 18 and the lower support pipe 18 are integrally formed via the frame 17.
For this reason, the lower support pipe 18 of the present invention has a recess 3 formed under the shaft pin 25 between the leg connectors 23.
It has the advantage that it will not fall even if it is placed at 0. On the other hand, in the conventional configuration, there is a drawback that the horizontal bar 11 on the lower side will fall unless it is arranged in the recess formed on the upper side of the shaft pin 25 between the corresponding leg connectors 23.

[0014]

As described above, according to the assembly of the present invention, the display plate 16 of the present invention is attached to the display plate supporting leg 15 of the present invention.
It has an advantage that it can be clamped vertically or obliquely with respect to the ground when it is clamped, and the structure of the display plate support leg is also simple.
