The operations performed by the operator will be described in order below.

First, the engagement between the engaging fittings 40a of the auxiliary plate 16 and the hooks 40b of the base plate 12 is released, and as shown in FIG. to the road side. Thus, as shown in FIGS. 5A and 5B, the connecting plate 14 is arranged horizontally above the beam Ga continuously to the upper end of the base plate 12, and the auxiliary plate 16 is connected to the connecting plate 14. is suspended from one end of the beam Ga and faces the inner surface of the beam Ga.

After that, an operation is performed to separate the display plate 18 from the auxiliary plate 16 by holding the end of the display plate 18 opposite to the hinge 24 . When this operation is performed, as shown in FIGS. 6(a) and 6(b), each member (first support plate 28, second support plate 30, and rotation limiting plate 32) that constitutes the support member 26 is moved to the hinge 34. , 36 and 38 as axes, and gradually open. Then, when the display plate 18 and the auxiliary plate 16 are opened at a predetermined angle, the protrusion 32b of the rotation limiting plate 32 comes into contact with the second support plate 30, whereby the first support plate 28 and the second support plate 30 are moved. are held in a state of extending in opposite directions with a hinge 36 interposed therebetween, and the display panel 18 is supported in a state opened at a predetermined angle with respect to the auxiliary panel 16. - 特許庁The predetermined angle is an angle at which the arrow 18a on the display panel 18 can be visually recognized from the following vehicle, and is set to about 30 to 70 degrees, for example.

After the emergency process is completed, the display plate 18 is rotated to the base plate 12 on the outside of the guardrail G and retracted by the opposite operation to the above operation, and the hook 40b is engaged with the engaging metal fitting 40a. together and fix.

The guide plate 10 for guiding traffic according to this embodiment is used by attaching it to the guardrail G in advance, and after being attached to the guardrail G, in a normal state in which traffic guiding is not performed, it is flatly folded and attached to the outer surface of the guardrail G. Since it has an overlapping structure, it is unlikely that it will fall over or be damaged by the wind pressure from a typhoon or a moving vehicle. In addition, in an emergency, the simple operation of unfolding the folded plates on the outer surface side of the guardrail G, moving the auxiliary plate 16 and the display plate 18 to the inner surface side of the guardrail G, and tilting the mounting angle of the display plate 18 can be performed. By doing so, the guidance display state can be set in a short time, and the line of sight guidance to the following vehicle can be promptly urged. Furthermore, worker safety can also be ensured. Similarly, the display panel 18 can be stowed safely and easily simply by rotating it to the outside of the guardrail G. As shown in FIG.

It should be noted that the guide plate for guiding traffic according to the present invention is not limited to the above embodiments. For example, in the case of the guide plate 10, the base plate 12, the connecting plate 14, the auxiliary plate 16, and the display plate 18 are all substantially rectangular, the base plate 12 being the largest, and the size of the auxiliary plate 16 and the display plate 18 being substantially the same. However, the shape and size of each plate can be freely changed as long as it can be switched to the guide display state by the above-described simple operation. The contents of instructions and symbols on the display plate are not limited as long as they are symbols or figures other than arrows that indicate directions, or other indications that are easy for the driver to understand.

Also, the support member is not limited to the structure of the support member 26 described above, and can be modified to have a different structure using other known techniques. For example, although the support member 26 cannot finely adjust the mounting angle of the display 18, it may be changed to a support member with an angle adjustment mechanism. Alternatively, the material of the rotation restricting plate 32 may be a ferromagnetic metal plate, and a magnet may be embedded in the second support plate 30 at a position where it abuts on the projecting portion 32b. Accordingly, when the display panel 18 is supported at a predetermined angle, the support member 26 is easily held in a straight state by the force of the magnets attracting the projecting portion 32b, thereby supporting the display panel 18 more stably. can be done.

The positioning mechanism is not limited to the positioning mechanism 40 described above as long as it positions the base plate and the auxiliary plate relative to each other in the normal state. For example, as shown in FIG. 2, the positioning mechanism 40 has a set of detachable engagement members (engagement fittings 40a and hooks 40b) attached to the lower ends of the auxiliary plate 16 and the base plate 12, respectively. However, it is possible to freely change the type, the number of sets, and the mounting positions of the engaging members, such as by providing two sets of right and left engaging members.

When attaching a base plate to a guardrail having a beam with a corrugated cross section, it is preferable to use a strip-shaped mounting bracket as shown in Fig. 3, and the shape of the mounting bracket can be changed as appropriate according to the shape of the beam. can be done. For example, if the beam Ga to be attached has a shape in which two ridges protrude toward the road, the mounting bracket is provided with two troughs so that the two ridges of the beam Ga can be accommodated inside. It is preferable to use the shape (the shape of the mounting bracket 42 in FIG. 3). If the shape of the beam G is such that three ridges protrude toward the road, the mounting bracket should be shaped to have three troughs so that the three ridges of the beam Ga can be accommodated inside. .

In addition, the guard member to be attached is not limited to the structure of the guard rail G in which the beam Ga with a corrugated cross section is installed on a plurality of posts Gb, and the base plate can be attached to the outer surface on the opposite side of the road, and the guide plate A guard member having a structure different from the guard rail, such as a concrete balustrade, may be used as long as it can be in the above-described normal state and guide display state.
