Description

【0001】
【発明の属する技術分野】
本発明は道路に設置する交通標識器に関する。
【0002】
【従来の技術】
一般に、道路の交差点やカーブ等には自動車の円滑な走行や安全性を確保するため、各種の交通標識器が設置されている。
【0003】
従来、この種の交通標識器は、各種交通標識に係わる図形を塗料等により表示した表示面部を有する標識板を備え、この標識板を地面に起設するポストの上部に取付けて構成していた。しかし、このような交通標識器は単なる表示板の域を出ないため、特に、夜間において認識しにくい問題があった。
【0004】
一方、標識板に反射板を用いることにより自動車のヘッドライトの反射光によって認識できるようにした標識器も、例えば、特開昭52−67599号公報等で知られているが、この種の標識器も基本的には自動車のヘッドライト光が標識器に当たる直前まで認識できず、遠方からの認識性及び注意の喚起性の面で十分とはいえない問題があった。
【0005】
そこで、これらの問題を解決するため、交通標識に係わる標識部分を発光ダイオードにより発光させ、夜間に外光が当たらなくても遠方から認識できるようにした標識器も、特開平2−20710号公報で提案されている。
【0006】
【発明が解決しようとする課題】
しかし、発光ダイオードを用いた従来の標識器は次のような解決すべき問題があった。
【0007】
第一に、一個の発光ダイオードは点として表示されるため、標識部分の輪郭を所定間隔の点で表示することも多いが、この場合、夜間に認識できるのは発光部分のみとなるため、標識部分が交通標識であること及びその交通標識の意図する注意点等を正確かつ速やかに認識しにくい。
【0008】
第二に、発光ダイオードは光の指向性が鋭い(狭い)ため、標識器を斜めから見た場合には明るさが不十分となり、標識器の設置状態や自動車の走行位置によって標識が不鮮明になりやすい。
【0009】
本発明はこのような従来の技術に存在する課題を解決したものであり、特に、夜間において標識を正確かつ速やかに認識できるとともに、斜めからでも標識を鮮明に視認できる交通標識器の提供を目的とする。
【0010】
【課題を解決するための手段及び実施の形態】
本発明は、交通標識に係わる図形Ax,Ay及び文字Bのうち少なくともいずれか一方を表示する表示面部2を有する交通標識器1を構成するに際して、表示面部2を、図形Ax,Ay及び文字Bのうち少なくともいずれか一方を表示する複数の発光ダイオード3…,4…を配列させたダイオード基板部5と、このダイオード基板部5の前方に配し、かつ発光ダイオード3…,4…の位置に対応した複数の透孔部6…,7…を有する表示板部8と、表示板部8の厚さと略同じ長さの栓本体部11…及びこの栓本体部11…の一端に一体形成した当該栓本体部11…よりも大径の鍔部12…を有することにより各透孔部6…,7…に嵌合して各透孔部6…,7…を閉塞し、かつ半透明に形成することにより発光ダイオード3…,4…の光を乱射する複数の乱射栓部9…,10…とを備えてなることを特徴とする。
【0011】
この場合、好適な実施の形態により、表示面部2には、図形Ax…を表示する第一発光部3mと図形Ax…に対応した文字Bを表示する第二発光部4mを設けるとともに、第一発光部3mと第二発光部4mを交互に発光させる動作制御部13を設ける。また、少なくとも近接する第一発光部3mの発光ダイオード3…と第二発光部4mの発光ダイオード4…には光を前方へのみ投光する筒状に形成した不透明のガイドカバー15…を装着することが望ましい。
【0012】
これにより、発光ダイオード3…,4…から発せられる光は、半透明の乱射栓部9…,10…を通過する際に乱射するとともに、この乱射光は前方外部に放射されるため、図形Ax…及び文字Bのうち少なくともいずれか一方を斜めからでも鮮明に視認できる。また、表示板部8と乱射栓部9…,10…のみの組合わせからなるため、例えば、表示板部8の内面に半透明板を重ね、かつ外面に透明保護カバーを重ねる構造などに比べて、部品点数及び素材量の削減、さらには表示面部2の薄厚化を図れる。特に、乱射栓部9…は、表示板部8の厚さと略同じ長さの栓本体部11…とこの栓本体部11…よりも大径の鍔部12…により形成したため、表示面部2の外面における凹部を無くすことができ、凹部が存在することに伴う弊害、例えば、土埃が溜まったり雨水が侵入しやすくなる不具合、さらには表示板部8の厚みにより横方からの視認性が悪化する不具合などを解消できる。一方、第一発光部3mと第二発光部4mを交互に発光させることにより、交通標識に係わる図形Ax…とこの図形Ax…に対応した文字Bを交互に表わせば、交通標識であること及びその交通標識の意図する注意点等を正確かつ速やかに認識できる。
【0013】
【実施例】
次に、本発明に係る好適な実施例を挙げ、図面に基づき詳細に説明する。
【0014】
まず、本実施例に係る交通標識器1の構成について、図1〜図8を参照して説明する。
【0015】
図3は交通標識器1の外観全体を示す。交通標識器1は細長い丸パイプにより形成したポスト21を備える。このポスト21は設置時に下端が地面Eに埋設されて上方に起立する。一方、ポスト21の上端には太陽電池ユニット22を取付ける。太陽電池ユニット22は上面に太陽電池23を有し、また、当該太陽電池23の出力電力を充電するバッテリ24を内蔵する(図8参照)。
【0016】
他方、ポスト21の上部には、標識ユニット25の裏面を上下一対の取付金具(取付バンド)26,27を用いて取付ける。標識ユニット25は図3及び図4に示すように、内部に中空部を有し、かつ外面に菱形の表示面部2を設ける。表示面部2には交通標識に係わる図形Ax,Ayを表示する。実施例は表示面部2の全体を黄色とし、中央に十字路交差点を表す十字の図形Axを、また、表示面部2の周縁に沿って描いた菱形枠状の図形Ayをそれぞれ黒色で描いたものである。このような交通標識は法令等により規定されている。
【0017】
一方、表示面部2には第一発光部3mを付設する。この第一発光部3mは5及び図6に示すように、図形Axの輪郭に沿って所定間隔置きに配した複数の発光ダイオード3…を備えるとともに、図形Ayに沿って所定間隔置きに配した複数の発光ダイオード3…を備える。また、表示面部2には、図形Axに対応した文字Bを象った第二発光部4mを付設する。この場合、図形Axが交差点を表すため、対応する文字は一時停止を表す「トマレ」の文字Bを選定する。第二発光部4mは図5及び図7に示すように、文字Bを象った複数の発光ダイオード4…を備える。
【0018】
図1に、表示面部2の具体的な構造を示す。表示面部2は表示基板部2pとその内面に対向して配したダイオード基板部5からなり、このダイオード基板部5の前面には上記各発光ダイオード3…及び4…がマウントされている。一方、表示基板部2pは表示板部8を備える。この表示板部8は1〜5mm程度の厚さを有し、各発光ダイオード3…及び4…に対応する位置には、表裏に貫通する直径5〜10mm程度の円形の透孔部6…,7…が複数形成されている。
【0019】
一方、光を乱射する多数の乱射栓部9…,10…を用意する。乱射栓部9(10も同じ)は、図2に示すように、半透明のポリカーボネイト等の合成樹脂素材或いはスリガラス等により一体成形したもので、栓本体部11と鍔部12を有する。栓本体部11は円柱状をなし、表示板部8の厚さと略同じ軸方向長さを有するとともに、鍔部12はこの栓本体部11の一端に一体形成し、かつ栓本体部11…よりも大径に形成する。そして、乱射栓部9…,10…は図1に示すように、各透孔部6…,7…に嵌合して各透孔部6…,7…を閉塞する。これにより、表示面部2の外面における凹部を無くすことができ、凹部が存在することに伴う弊害、例えば、土埃が溜まったり雨水が侵入しやすくなる不具合、さらには表示板部8の厚みにより横方からの視認性が悪化する不具合などを解消できる。また、表示板部8と乱射栓部9…,10…のみの組合わせからなるため、例えば、表示板部8の内面に半透明板を重ね、かつ外面に透明保護カバーを重ねる構造などに比べて、部品点数及び素材量の削減、さらには表示面部2の薄厚化を図れる。なお、乱射栓部9…,10…を各透孔部6…,7…に嵌着した際には、接着剤等を塗布することにより抜止めを行う。
【0020】
ところで、通常、発光ダイオード3…,4…から発せられる光の指向性は鋭い(狭い)ため、十分な明るさが得れるのは正面を起点に比較的狭い範囲である。しかし、各発光ダイオード3…(4…側も同じ)の前方には乱射栓部9…を配するため、発光ダイオード3…の光は乱射栓部9…により乱射し、この乱射光が透孔部6…から前方外部に放射される。この結果、発光ダイオード3…の指向性が改善され、斜めからでも鮮明に視認できる。なお、発光ダイオード3…と乱射栓部9…の間隔は、0.1〜20mmの範囲で発光ダイオードの特性により設定することが望ましい。また、この間隔を選定することにより、光の指向性を変えることができる。
【0021】
さらに、標識ユニット25の内部には、第一発光部3mと第二発光部4mを交互に発光させる制御を行う制御本体部30を備える。制御本体部30には図8に示すように、前記バッテリ24及び明暗を検出する光センサ31をそれぞれ接続する。なお、制御本体部30,光センサ31,太陽電池23及びバッテリ24は動作制御部13を構成する。
【0022】
次に、本実施例に係る交通標識器1の動作について、図5〜図9を参照して説明する。
【0023】
まず、昼間は、光センサ31が明るさを検出するため、制御本体部30は動作停止状態となる。したがって、第一発光部3m及び第二発光部4m共に発光しない。よって、昼間は図5に示すように、表示面部2に表示される交通標識(図形Ax,Ay)をそのまま視認できる。また、昼間は太陽電池23の出力電力がバッテリ24に充電される。
【0024】
一方、暗くなり、光センサ31が一定の暗さを検出すれば、制御本体部30は第一発光部3mと第二発光部4mを交互に発光させる制御を実行する。即ち、図9に示すように、Pd時点において光センサ31が一定の暗さを検出することにより、第一発光部3mと第二発光部4mが交互に点灯と消灯を繰り返す。この場合、点灯及び消灯の時間は数秒程度に設定できるとともに、時間は制御本体部30の調整機能により任意の設定できる。
【0025】
図6は第一発光部3mが点灯した状態を示す。第一発光部3mは交通標識に係わる図形Ax,Ayを表わす。他方、図7は第二発光部4mが点灯した状態を示す。第二発光部4mは図形Axに対応した「トマレ」の文字Bを表示する。なお、夜が明け、図9中Pr時点において、明るくなった場合には、光センサ31が明るさを検出するため、制御本体部30は動作停止状態となる。したがって、第一発光部3m及び第二発光部4mの発光は共に停止する。
【0026】
よって、交通標識に係わる図形Ax…とこの図形Ax…に対応した文字Bが交互に表わされ、交通標識であること及びその交通標識の意図する注意点等を正確かつ速やかに認識できる。
【0027】
次に、各種変更実施例について、図10〜図15を参照して説明する。図10は乱射栓部9(10も同じ)の変更実施例であり、乱射栓部9における鍔部12を有する一端面に凹部9oを設けた。これにより、乱射栓部9(栓本体部11)を薄くできるため、光の透過率を高めることができるとともに、素材量を低減できる。
【0028】
また、図11に示す変更実施例は、第一発光部3mの発光ダイオード3…と第二発光部4mの発光ダイオード4…が近接した場合に、光を前方へのみ投光する筒状に形成した不透明のガイドカバー15…を各発光ダイオード3…,4…に装着したものである。発光ダイオード3…と4…は交互に点灯を繰返すため、発光ダイオード3…と4…が近接した場合、一方の発光ダイオード3の光が隣の乱射栓部10に漏れる虞れがあり、これを解消するため、ガイドカバー15によってり、発光ダイオード3の光が前方に配される乱射栓部9にのみ照射されるようにした。
【0029】
一方、図12に示す変更実施例は、文字Bを標識ユニット25とは別体に構成した文字ユニット35に設けたものであり、第二発光部4mは文字ユニット35に配設される。したがって、標識ユニット25には図形Ax,Ayのみが設けられる。なお、文字Bは「徐行」を示す。文字ユニット35の基本的な内部構造及び機能等は図1〜図8に示した実施例と同じである。このため、図12において図3と同一部分には同一符号を付し、その構成を明確にするとともに、詳細な説明は省略する。
【0030】
また、図13は三差路交差点を表す横T字の図形Ax及び表示面部2の周縁に沿って描いた菱形枠状の図形Ayと、この図形Axに対応する「徐行」の文字Bを表示した例を示す。さらに、図14は二本のポスト21a,21bに取付けた長方形の標識ユニット25に、進行方向を表す直線矢印の図形Ax及びこの図形Axに対応する「スピードおとせ」の文字Bを表示した例を示す。なお、図14において発光ダイオード3…は標識ユニット25の周縁に沿っても配される。また、図15は制限速度を表す「50」の図形Ax及び表示面部2の周縁に沿って描いた円形枠状の図形Ayと、標識ユニット25とは別体に構成した文字ユニット35に当該図形Axに対応する「スピード注意」の文字Bを表示した例を示す。この場合、文字ユニット35は無くてもよい。なお、「50」の表示は本来数字であるが本発明では図形Axとして位置付けられる。また、発光ダイオード3…(透孔部6…)は「50」の図形Ax及びAyに沿って配される。図13〜図15に示す変更実施例も基本的な構造及び機能は図1〜図8に示した実施例と同じである。このため、各図において図1〜図8と同一部分には同一符号を付し、その構成を明確にするとともに、詳細な説明は省略する。
【0031】
以上、実施例について詳細に説明したが、本発明はこのような実施例に限定されるものではなく、細部の構成,形状等において本発明の精神を逸脱しない範囲で任意に変更できる。特に、表示する交通標識は例示に限らず、他の各種交通標識が適用される。また、本発明における「図形」とは標識を意味するものであれば、図15に示すような数字をはじめ、文字や符号等も含まれるとともに、本発明における「文字」には数字や符号等も含まれる。一方、乱射栓部はいわゆるスリガラス状の半透明であっもよいし、透明な素材に赤,黄,青,ブラウン等の薄い色を混ぜた透視性のある合成樹脂類やガラス類であってもよい。さらに、発光ダイオードは実施例(変更実施例)のように直接投射してもよいし、光ファイバー等を介して間接的に投射してもよい。
【0032】
【発明の効果】
このように、本発明に係る交通標識器は、表示面部を、図形及び文字のうち少なくともいずれか一方を表示する複数の発光ダイオードを配列させたダイオード基板部と、このダイオード基板部の前方に配し、かつ発光ダイオードの位置に対応した複数の透孔部を有する表示板部と、表示板部の厚さと略同じ長さの栓本体部及びこの栓本体部の一端に一体形成した当該栓本体部よりも大径の鍔部を有することにより各透孔部に嵌合して各透孔部を閉塞し、かつ半透明に形成することにより発光ダイオードの光を乱射する複数の乱射栓部とを備えて構成したため、次のような顕著な効果を奏する。
【0033】
▲1▼ 標識の表示に発光ダイオードを使用した場合でも、斜めから鮮明に視認することができ、もって、標識器の設置状態や自動車の走行位置に拘わりなく確実に認識できる。
【0034】
▲2▼ 表示面部に、図形を表示する第一発光部と図形に対応した文字を表示する第二発光部を設けるとともに、第一発光部と第二発光部を交互に発光させる動作制御部を設けることにより、交通標識及びその交通標識の意図する注意点等を正確かつ速やかに認識することができる。
【0035】
▲3▼ 表示板部と乱射栓部のみの組合わせからなるため、部品点数及び素材量の削減、さらには表示面部の薄厚化を図れるとともに、表示面部の外面における凹部を無くすことにより、凹部が存在することに伴う弊害、例えば、土埃が溜まったり雨水が侵入しやすくなる不具合、さらには表示板部の厚みにより横方からの視認性が悪化する不具合などを解消できる。

BACKGROUND OF THE INVENTION
The present invention relates to a traffic sign installed on a road.
[0002]
[Prior art]
In general, various traffic signs are installed at intersections and curves of roads in order to ensure smooth driving and safety of automobiles.
[0003]
Conventionally, this type of traffic signage is provided with a signboard having a display surface portion on which graphics relating to various traffic signs are displayed by paint or the like, and this signboard is attached to the upper part of a post erected on the ground. . However, since such a traffic sign does not leave the area of a mere display board, there is a problem that it is difficult to recognize especially at night.
[0004]
On the other hand, a marker that can be recognized by reflected light from a headlight of an automobile by using a reflector as the marker plate is also known, for example, in Japanese Patent Laid-Open No. 52-67599. Basically, the vessel could not be recognized until just before the headlight of the automobile hits the sign, and there was a problem that it was not sufficient in terms of recognizability from far away and alertness.
[0005]
Therefore, in order to solve these problems, a signage device in which a sign part related to a traffic sign is made to emit light by a light emitting diode so that it can be recognized from a long distance without being exposed to outside light at night is disclosed in Japanese Patent Laid-Open No. 2-20710. Proposed in
[0006]
[Problems to be solved by the invention]
However, the conventional marker using the light emitting diode has the following problems to be solved.
[0007]
First, since one light-emitting diode is displayed as a point, the outline of the sign part is often displayed at a predetermined interval point, but in this case, only the light-emitting part can be recognized at night. It is difficult to accurately and promptly recognize that the part is a traffic sign and the cautionary point intended by the traffic sign.
[0008]
Secondly, light emitting diodes have a sharp (narrow) directivity of light, so that when the sign is viewed from an angle, the brightness is insufficient, and the sign becomes unclear depending on the installation state of the sign and the driving position of the car. Prone.
[0009]
The present invention solves such problems existing in the prior art, and in particular, provides a traffic sign that can recognize a sign accurately and promptly at night and can clearly see the sign even from an oblique direction. And
[0010]
[Means for Solving the Problems and Embodiments]
In constructing the traffic sign 1 having the display surface portion 2 for displaying at least one of the graphics Ax, Ay and the letter B related to the traffic sign, the display surface portion 2 is changed to the graphics Ax, Ay and the character B. Are arranged in front of the diode substrate part 5 and arranged at the position of the light-emitting diodes 3... 4. The display plate portion 8 having a plurality of corresponding through-hole portions 6, 7, the plug body portion 11 having a length substantially the same as the thickness of the display plate portion 8, and one end of the plug body portion 11. By having a flange 12 having a diameter larger than that of the plug body 11, the plug body is fitted into the through holes 6, 7, and closes the through holes 6, 7, and is translucent. The light of the light emitting diodes 3 ..., 4 ... is scattered by forming That a plurality of shootings plug portion 9 ..., and characterized in that it comprises 10 ... and.
[0011]
In this case, according to a preferred embodiment, the display surface 2 is provided with a first light emitting unit 3m for displaying the graphic Ax... And a second light emitting unit 4m for displaying the letter B corresponding to the graphic Ax. An operation control unit 13 for alternately emitting light from the light emitting unit 3m and the second light emitting unit 4m is provided. Further, at least the light emitting diodes 3 ... of the first light emitting unit 3m and the light emitting diodes 4 ... of the second light emitting unit 4m are mounted with opaque guide covers 15 formed in a cylindrical shape for projecting light only forward. It is desirable.
[0012]
As a result, the light emitted from the light emitting diodes 3, 4, scatters when passing through the semi-transparent turbulent plugs 9, 10, and the radiant light is radiated to the outside of the front, so that the figure Ax ... and at least one of the letters B can be clearly seen even from an oblique direction. Moreover, since it consists of a combination of only the display plate 8 and the flash plugs 9 ..., 10 ..., for example, compared to a structure in which a translucent plate is stacked on the inner surface of the display plate 8 and a transparent protective cover is stacked on the outer surface. Thus, the number of parts and the amount of material can be reduced, and the display surface portion 2 can be made thinner. In particular, the random plug part 9 is formed by a plug body part 11 having a length substantially the same as the thickness of the display plate part 8 and a flange part 12 having a diameter larger than that of the plug body part 11. The concave portion on the outer surface can be eliminated, and the adverse effects caused by the presence of the concave portion, for example, the problem that dust accumulates or rainwater easily enters, and further the visibility from the side is deteriorated due to the thickness of the display plate portion 8. Trouble can be solved. On the other hand, if the first light emitting unit 3m and the second light emitting unit 4m are caused to emit light alternately so that the figure Ax... Related to the traffic sign and the letter B corresponding to the figure Ax. It is possible to accurately and promptly recognize cautionary points intended by the traffic signs.
[0013]

As shown in FIG. 2, the random injection plug 9 (10 is the same) is integrally formed of a synthetic resin material such as translucent polycarbonate or ground glass, and has a plug body 11 and a flange 12. The plug body 11 has a cylindrical shape, has an axial length substantially the same as the thickness of the display plate 8, and the flange 12 is integrally formed at one end of the plug body 11, and from the plug body 11. Is also formed in a large diameter. As shown in FIG. 1, the random plug parts 9..., 10... Fit into the through holes 6. As a result, the concave portion on the outer surface of the display surface portion 2 can be eliminated, and there are adverse effects associated with the presence of the concave portion, for example, a problem that dust accumulates or rainwater easily enters, and further, the thickness of the display plate portion 8 It is possible to eliminate problems such as poor visibility. Moreover, since it consists of a combination of only the display plate 8 and the flash plugs 9 ..., 10 ..., for example, compared to a structure in which a translucent plate is stacked on the inner surface of the display plate 8 and a transparent protective cover is stacked on the outer surface. Thus, the number of parts and the amount of material can be reduced, and the display surface portion 2 can be made thinner. When the random plug parts 9... 10 are fitted into the respective through-hole parts 6... 7, they are prevented from being removed by applying an adhesive or the like.
[0020]
By the way, since the directivity of light emitted from the light emitting diodes 3... 4 is usually sharp (narrow), sufficient brightness can be obtained in a relatively narrow range starting from the front. However, since the random plug portions 9 are arranged in front of the respective light emitting diodes 3 (4 is also the same), the light from the light emitting diodes 3 is scattered by the random plug portions 9 and the irregular light is transmitted through the holes. Radiated from the front part 6 to the front outside. As a result, the directivity of the light-emitting diodes 3 is improved and can be clearly seen even from an oblique direction. The distance between the light emitting diodes 3 ... and the flash plugs 9 is preferably set in the range of 0.1 to 20 mm according to the characteristics of the light emitting diodes. Moreover, the directivity of light can be changed by selecting this interval.
[0021]
Furthermore, inside the label unit 25, a control main body 30 that performs control to alternately emit light from the first light emitting unit 3m and the second light emitting unit 4m is provided. As shown in FIG. 8, the battery 24 and an optical sensor 31 for detecting light and darkness are connected to the control main body 30 respectively. Note that the control main body 30, the optical sensor 31, the solar cell 23, and the battery 24 constitute an operation control unit 13.
[0022]
Next, operation | movement of the traffic sign 1 which concerns on a present Example is demonstrated with reference to FIGS.
[0023]
First, in the daytime, since the optical sensor 31 detects the brightness, the control main body 30 is in an operation stop state. Accordingly, neither the first light emitting unit 3m nor the second light emitting unit 4m emits light. Therefore, as shown in FIG. 5, the traffic signs (graphics Ax, Ay) displayed on the display surface unit 2 can be visually recognized as they are during the daytime. In addition, the output power of the solar cell 23 is charged in the battery 24 during the daytime.
[0024]
On the other hand, if it becomes dark and the optical sensor 31 detects a certain darkness, the control main body 30 executes control to alternately emit light from the first light emitting unit 3m and the second light emitting unit 4m. That is, as shown in FIG. 9, when the optical sensor 31 detects a certain darkness at the time Pd, the first light emitting unit 3m and the second light emitting unit 4m are alternately turned on and off. In this case, the turn-on and turn-off times can be set to about several seconds, and the time can be arbitrarily set by the adjustment function of the control main body 30.
[0025]
FIG. 6 shows a state in which the first light emitting unit 3m is lit. The first light emitting unit 3m represents figures Ax and Ay related to traffic signs. On the other hand, FIG. 7 shows a state in which the second light emitting unit 4m is lit. The second light emitting unit 4m displays the “B” character “B” corresponding to the graphic Ax. In addition, when the day is dawn and it becomes bright at the time point Pr in FIG. 9, the optical sensor 31 detects the brightness, so that the control main body 30 is in an operation stop state. Therefore, both the first light emitting unit 3m and the second light emitting unit 4m stop light emission.
[0026]
Therefore, the figure Ax... Related to the traffic sign and the character B corresponding to the figure Ax... Are alternately displayed, and the traffic sign and the cautionary point intended by the traffic sign can be recognized accurately and promptly.
[0027]
Next, various modified embodiments will be described with reference to FIGS. FIG. 10 shows a modified embodiment of the random injection plug portion 9 (10 is the same), and a concave portion 9o is provided on one end surface of the random injection plug portion 9 having the flange 12. Thereby, since the blaze plug part 9 (plug main body part 11) can be made thin, while being able to raise the transmittance | permeability of light, the amount of materials can be reduced.
[0028]
Further, the modified embodiment shown in FIG. 11 is formed in a cylindrical shape that projects light only forward when the light emitting diodes 3... Of the first light emitting unit 3 m and the light emitting diodes 4 of the second light emitting unit 4 m are close to each other. The opaque guide covers 15 are attached to the light emitting diodes 3. Since the light emitting diodes 3 ... and 4 ... repeat lighting alternately, when the light emitting diodes 3 ... and 4 ... are close to each other, there is a possibility that the light of one light emitting diode 3 leaks to the adjacent random plug portion 10, which In order to solve the problem, the guide cover 15 allows the light from the light emitting diode 3 to be irradiated only to the astigmatism plug portion 9 disposed in front.
[0029]
On the other hand, in the modified embodiment shown in FIG. 12, the letter B is provided in the letter unit 35 configured separately from the marker unit 25, and the second light emitting unit 4 m is provided in the letter unit 35. Therefore, the sign unit 25 is provided with only the graphics Ax and Ay. Note that the letter B indicates “deceleration”. The basic internal structure and functions of the character unit 35 are the same as those of the embodiment shown in FIGS. Therefore, in FIG. 12, the same parts as those in FIG. 3 are denoted by the same reference numerals, the configuration thereof is clarified, and detailed description is omitted.
[0030]
FIG. 13 shows a horizontal T-shaped graphic Ax representing a three-way intersection, a rhombus-shaped graphic Ay drawn along the periphery of the display surface portion 2, and a “Blowing” character B corresponding to the graphic Ax. An example is shown. Further, FIG. 14 shows an example in which a rectangular sign unit 25 attached to the two posts 21a and 21b is displayed with a straight arrow graphic Ax indicating the traveling direction and a character "B" of speed "corresponding to the graphic Ax. Show. In FIG. 14, the light emitting diodes 3... Further, FIG. 15 shows a graphic Ax of “50” representing the speed limit, a circular frame-shaped graphic Ay drawn along the periphery of the display surface 2, and a character unit 35 configured separately from the sign unit 25. An example is shown in which a letter B of “speed attention” corresponding to Ax is displayed. In this case, the character unit 35 may be omitted. The display of “50” is originally a number, but in the present invention, it is positioned as a graphic Ax. The light-emitting diodes 3 (through holes 6) are arranged along the “50” figures Ax and Ay. The basic structure and functions of the modified embodiments shown in FIGS. 13 to 15 are the same as those of the embodiments shown in FIGS. For this reason, in each figure, the same code | symbol is attached | subjected to FIGS. 1-8, the detailed description is abbreviate | omitted while clarifying the structure.
[0031]
Although the embodiments have been described in detail above, the present invention is not limited to such embodiments, and the detailed configuration, shape, and the like can be arbitrarily changed without departing from the spirit of the present invention. In particular, the traffic signs to be displayed are not limited to the examples, and other various traffic signs are applied. In addition, as long as the “graphic” in the present invention means a sign, it includes not only numbers as shown in FIG. 15 but also letters, symbols, etc., and “characters” in the present invention include numbers, symbols, etc. Is also included. On the other hand, the spray plug part may be a so-called frosted glass-like translucent, or it may be a transparent synthetic resin or glass in which a light material such as red, yellow, blue or brown is mixed with a transparent material. Good. Further, the light emitting diode may be projected directly as in the embodiment (modified embodiment) or indirectly through an optical fiber or the like.
