Description

[Detailed description of the invention] The present invention relates to a sign board equipped with folding legs.The folding legs can be folded up when not in use to facilitate handling such as carrying, and the signs can be attached to the surface of the mounting plate. The board can be replaced freely and easily, so that the most appropriate sign can be displayed depending on the situation, such as at an accident site or a construction work site.

Embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a sign board with information signs, warning signs a, etc. displayed on its front surface, and on its back side, a part of the back side is an open groove 3, and guide rails 2, 2 with open both ends are provided in parallel. . Reference numeral 4 designates a vertically straight-shaped mounting plate, through which sliders 5 consisting of bolts are passed at two places, upper and lower, and each slider is passed through from the open side of the guide rails 2, 2. ,5 neck 6,6
protrudes backward from the open grooves 3, 3 and attaches to the mounting plate 4.
After passing it through the mounting hole of the mounting plate 4, tighten the nuts 7, 7.
Fixed with. A horizontal straight-shaped shaft support plate 8 that protrudes left and right is fixed to the back of the mounting plate 4, and a pair of first links 1 that are free to protrude rearward are attached to both ends of the support plate 8.
0 and 10 are connected by shafts 10a and 10a, and a second link piece 1 is attached to the rear end of the first links 10 and 10.
1 and 11 are respectively pivotally supported by shafts 11a and 11a, and the rear ends of the second links 11 and 11 are overlapped and connected by one shaft element 12 to form a folding leg 9.
Configure. A shaft 1 is attached to the first links 10, 10.
A stopper piece 1 that engages with each outer side of the second link pieces 11, 11 is provided on the outer side of the rear end beyond 1a, 11a.
3 and 13 are bent at right angles to form a symmetrical shape, and the first
The second link pieces 11, 11 extending linearly with the links 10, 10 are prevented from bending in the arrow x, x direction about the shafts 11a, 11a.

In this embodiment, the first links 10, 10 and the second link pieces 11, 11 of the folding leg 9 are extended linearly as shown in solid lines in FIG. 2 and in FIG. The rear ends of the link pieces 11, 11 and the shaft 12 are grounded, and the sign board 1 is erected diagonally. When the sign board 1 is not used, the first links 10, 10 forming the folding legs 9 are opened outward, the second link pieces 11, 11 are bent approximately 180 degrees around the shafts 11a, 11a, and the Fold it at the back of the support plate 8. The sign board 1 is replaced by removing the sliders 5 from the sides of the guide rails 2, 2, and fitting the guide rails 2, 2 of a new sign board 1 onto the sliders 5.

The present invention has the structure clarified above,
Installing guide rails 2, 2 on the back side of the sign board 1, with a part of the back side having an open groove 3 and both ends open.
Since the slider 5 of the mounting plate 4 of the folding leg 9 is passed through the rails 2, 2 from the side, the sign board 1 can be removed by loosening the nuts 7, 7 screwed onto the sliders 5, 5. Replacement work such as removing and replacing the mounting plate 4 from the mounting plate 4 can be easily performed. In addition, when transporting and storing the sign board 1, the folding legs 9 can be folded on the back of the sign board 1 to reduce its bulk.When the sign board 1 is used at an accident site or a work site,
The folding legs can be quickly extended.
Furthermore, by freely attaching a suitable sign board to the mounting plate 4 of the folding legs 9 as described above, it is possible to display any sign.
