高速道路で事故が発生して緊急の事故処理を行う場合、特許文献１の通行案内用看板は、ガードレールに設置するのに手間が掛かるので、交通誘導用の矢印を短時間でセットすることが難しい。 When an accident occurs on a highway and emergency accident handling is performed, it takes time to install the traffic guidance signboard of Patent Document 1 on the guardrail, so it is possible to set the traffic guidance arrow in a short time. difficult.

例えば、片側２車線あるいは３車線の追越車線で事故が発生した場合、追越車線を走行してくる後続車を走行車線に誘導するため、複数の矢印板を中央分離帯側のガードレールにセットしなければならない。一般に中央分離帯側には広い路肩がないので、作業車両が現場に到着すると、走行車線側の路肩に停車させざるを得ない。そして、作業者は、矢印板の機材を作業車両から降ろし、これを持って走行車線及び追越車線を横断して中央分離帯側のガードレールまで運ばなければならないので、非常に危険である。したがって、作業者の安全確保のため、交通誘導用の矢印板等の案内板は、事故が発生しやすい場所にあらかじめ設置しておき、事故が発生した時に短時間で簡単にセットできるものであることが望ましい。 For example, if an accident occurs in an overtaking lane with two or three lanes on each side, multiple arrow plates are set on the guardrail on the median strip side in order to guide the following vehicle traveling in the overtaking lane to the driving lane. Must. Generally, there is no wide shoulder on the median strip side, so when the work vehicle arrives at the site, it has to stop on the shoulder on the driving lane side. Then, the worker must take the equipment of the arrow plate off the work vehicle and carry it across the traveling lane and the overtaking lane to the guardrail on the median strip side, which is extremely dangerous. Therefore, in order to ensure the safety of workers, guide boards such as arrow boards for traffic guidance can be installed in advance in places where accidents are likely to occur, and can be easily set in a short time when an accident occurs. Is desirable.

Now, as shown in FIGS. 5A and 5B, the connecting plate 14 is continuously arranged laterally above the beam Ga at the upper end of the base plate 12, and the auxiliary plate 16 is provided with the connecting plate 14. It is suspended from one end of the beam and faces the inner surface of the beam Ga.

その後、表示板１８の、ヒンジ２４と反対側の端部を持って、表示板１８を補助板１６から離間させる操作を行う。この操作を行うと、図６（ａ）、（ｂ）に示すように、支持部材２６を構成する各部材（第一支持板２８、第二支持板３０及び回動制限板３２）がヒンジ３４，３６，３８を軸に各々回動し、徐々に開いていく。そして、表示板１８と補助板１６とが所定の角度に開いたところで回動制限板３２の突出部３２ｂが第二支持板３０に当接し、これによって第一支持板２８及び第二支持板３０が互いにヒンジ３６を挟んで反対方向に延びた状態に保持され、表示部材１８が、補助板１６に対して所定の角度開いた状態に支持される。所定の角度とは、後続車から表示板１８の矢印１８ａが良好に視認できる角度であり、例えば３０～７０度程度に設定される。 After that, the display plate 18 is operated to separate the display plate 18 from the auxiliary plate 16 by holding the end portion of the display plate 18 opposite to the hinge 24. When this operation is performed, as shown in FIGS. 6A and 6B, each member (first support plate 28, second support plate 30 and rotation limiting plate 32) constituting the support member 26 becomes a hinge 34. , 36, 38 rotate around the axis, respectively, and gradually open. Then, when the display plate 18 and the auxiliary plate 16 are opened at a predetermined angle, the protruding portion 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 brought into contact with each other. Are held in a state of extending in opposite directions with the hinge 36 interposed therebetween, and the display member 18 is supported in a state of being opened at a predetermined angle with respect to the auxiliary plate 16. The predetermined angle is an angle at which the arrow 18a of the display board 18 can be clearly seen from the following vehicle, and is set to, for example, about 30 to 70 degrees.

緊急時の処理等が終了した後は、上記の操作とは逆の操作により、表示板１８をガードレールＧの外側のベース板１２に回動させて退避させ、フック４０ｂを係合金具４０ａに係合して固定する。 After the emergency processing or the like is completed, the display plate 18 is rotated to the base plate 12 on the outside of the guardrail G and retracted by the reverse operation of the above operation, and the hook 40b is engaged with the engaging metal fitting 40a. Fit and fix.

この実施形態の交通誘導用の案内板１０は、あらかじめ、ガードレールＧに取り付けて使用され、ガードレールＧに取り付けられた後、交通誘導を行わない通常状態では、平たく折り畳まれてガードレールＧの外側面に重なった構造になるので、台風の突風や走行車からの風圧を受けて倒れたり破損したりする可能が低い。また、緊急時、ガードレールＧの外面側に折り畳まれた各板を広げ、補助板１６及び表示板１８ガードレールＧの内面側に移動させ、さらに表示板１８の取り付け角度を斜めするという簡単な操作を行うことによって、短時間で案内表示状態にセットすることができ、速やかに後続車への視線誘導を促すことができる。さらに、作業者の安全も確保することができる。また、表示板１８の収納も同様に、ガードレールＧの外側に回動させるだけで、安全に容易に行うことができる。 The guide plate 10 for traffic guidance of this embodiment is used by being attached to the guardrail G in advance, and after being attached to the guardrail G, in a normal state where traffic guidance is not performed, the guide plate 10 is folded flat and is attached to the outer surface of the guardrail G. Since it has an overlapping structure, it is unlikely that it will fall or be damaged by the gust of a typhoon or the wind pressure from a traveling vehicle. Further, in an emergency, a simple operation of unfolding each plate folded to 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 further tilting the mounting angle of the display plate 18 is 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 promoted. Furthermore, the safety of workers can be ensured. Similarly, the display plate 18 can be stored safely and easily only by rotating it to the outside of the guardrail G.

なお、本発明の交通誘導用の案内板は、上記実施形態に限定されるものではない。例えば、上記案内板１０の場合、ベース板１２、連結板１４、補助板１６及び表示板１８が全て略長方形で、ベース板１２が最も大きく、補助板１６と表示板１８の大きさがほぼ同じに設定されているが、上述した簡単な操作で案内表示状態に切り替えることができるものであれば、各板の形状や大きさは、自由に変更することができる。表示板の指示内容や記号も、矢印以外に方向を示す記号や図形、その他運転者から見て指示内容が分かりやすい表示であれば、その内容は問わないものである。 The guide plate for traffic guidance of the present invention is not limited to the above embodiment. 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 is the largest, and the auxiliary plate 16 and the display plate 18 are almost the same size. However, the shape and size of each plate can be freely changed as long as it can be switched to the guidance display state by the simple operation described above. The contents of instructions and symbols on the display board are not limited as long as they are symbols and figures indicating directions other than arrows, and other indications that are easy for the driver to understand.

また、支持部材は、上記の支持部材２６の構造に限定されず、他の公知技術を利用して異なる構造に変更することができる。例えば、支持部材２６は、表示何１８の取り付け角度を微調整することはできないが、角度調節機構付きの支持部材に変更してもよい。また、回動制限板３２の素材を強磁性金属板とし、第二支持板３０の、突出部３２ｂと当接する位置に磁石を埋設した構造にしてもよい。これによって、表示板１８を所定の角度で支持する時、磁石が突出部３２ｂを吸着する力によって支持部材２６が真っすぐに伸びた状態に保持されやすくなり、表示板１８をより安定に支持することができる。 Further, the support member is not limited to the structure of the support member 26 described above, and can be changed to a different structure by using other known techniques. For example, the support member 26 may be changed to a support member with an angle adjustment mechanism, although the mounting angle of the display number 18 cannot be finely adjusted. Further, the material of the rotation limiting plate 32 may be a ferromagnetic metal plate, and the structure may be such that the magnet is embedded in the position of the second support plate 30 in contact with the protruding portion 32b. As a result, when the display plate 18 is supported at a predetermined angle, the support member 26 is easily held in a straightened state by the force of the magnet attracting the protrusion 32b, and the display plate 18 is supported more stably. Can be done.

位置決め機構は、通常状態の時にベース板及び補助板を相互に位置決めするものであればよく、上記の位置決め機構４０の形態に限定されない。例えば、位置決め機構４０は、図２に示すように、補助板１６及びベース板１２の各下端部に、相互に着脱可能な係合部材（係合金具４０ａ、フック４０ｂ）を１組取り付けたものであるが、左右２組の係合部材を設ける等、係合部材の種類、組数、取り付け位置は自由に変更することができる。 The positioning mechanism may be any as long as it positions the base plate and the auxiliary plate with each other in a normal state, and is not limited to the form of the positioning mechanism 40 described above. For example, as shown in FIG. 2, the positioning mechanism 40 has one set of mutually removable engaging members (engagement fittings 40a, hooks 40b) attached to the lower ends of the auxiliary plate 16 and the base plate 12. However, the type, number of sets, and mounting position of the engaging members can be freely changed, such as providing two sets of the left and right engaging members.

波形断面のビームを有したガードレールにベース板を取り付ける時は、図３に示すように、帯状の取り付け金具を使用することが好ましく、取り付け金具の形状は、ビームの形状に合わせて適宜変更することができる。例えば、取り付け対象のビームＧａの形状が、２つの突条が道路側に膨出している形状の場合、取り付け金具は、ビームＧａの２つの突条が内側に収まるように２つの谷部を設けた形状（図３の取り付け金具４２の形状）にすることが好ましい。ビームＧの形状が３つの突条が道路側に膨出している形状の場合は、取り付け金具は、ビームＧａの３つの突条が内側に収まるように３つの谷部を設けた形状にするとよい。 When mounting the base plate on a guardrail having a beam with a corrugated cross section, it is preferable to use a band-shaped mounting bracket as shown in FIG. 3, and the shape of the mounting bracket should be appropriately changed according to the shape of the beam. Can be done. For example, when the shape of the beam Ga to be attached is such that the two ridges bulge toward the road side, the mounting bracket is provided with two valleys so that the two ridges of the beam Ga fit inside. It is preferable to have a shape (shape of the mounting bracket 42 in FIG. 3). If the shape of the beam G is such that three ridges bulge toward the road side, the mounting bracket should have a shape with three valleys so that the three ridges of the beam Ga fit inside. ..

また、取り付け対象のガード部材は、波形断面のビームＧａを複数の支柱Ｇｂに架設したガードレールＧの構造に限定されず、ベース板を道路と反対側の外側面に取り付けること可能で、案内板を上述した通常状態及び案内表示状態にできるものであれば、ガードレールとは異なる構造の、例えばコンクリート製の壁高欄等のガード部材であってもよい。 Further, the guard member to be attached is not limited to the structure of the guardrail G in which the beam Ga of the corrugated cross section is erected on a plurality of columns Gb, and the base plate can be attached to the outer surface on the opposite side to the road, and the guide plate can be attached. A guard member having a structure different from that of the guardrail, such as a concrete wall railing, may be used as long as it can be in the normal state and the guidance display state described above.
