Description

本発明は、両面テープの一面に反射素子を１列又は２列に並べた長尺体から成り、ガードレールやポール等の路側構造物に取り付ける際には、必要な長さに両面テープを切断して切り離し、剥離紙を剥がして貼り付けると云う利用のされ方をする視線誘導標に関する。   The present invention consists of a long body in which reflective elements are arranged in one or two rows on one side of a double-sided tape. When attaching to a roadside structure such as a guardrail or a pole, the double-sided tape is cut to the required length. The present invention relates to a line-of-sight guidance mark that is used in such a manner that it is cut off and peeled off and attached.

従来のこの種視線誘導標は、図８及び図９に示すように、平板状の反射素子１００を両面テープ１０２の一面に並べて取り付けた形態から成り、反射素子１００の表面１０１は平面である。
このため、自動車のヘッドライトからの入射光ｒは、図９に示すように、反射素子１００の表面においてｒ1のように反射してしまう。このため、斜め方向からヘッドライトの光が照射した場合には、反射体としての用をなさないと云う問題がある。また、図１０に示すように、ポール１０３に捲きつけて視線誘導標を取り付けた場合、矢印ａ方向から自動車のヘッドライトの光が照射されると、再帰反射光は斜線で示された部分の反射素子１００からだけとなり、十分に注意を喚起する光量とはならない。同様の問題は、ガードレールに取り付けた場合も発生している。
このような問題を解決する手段として、次のような提案がある。
特開平９-３０２６３１号公報 この特許文献１に掲載の発明は、設置費用が安価でかり、かつ、設置作業がきわめて簡単である視線誘導標の提供を目的として、請求項１に記載の発明においては、裏面が路側構造物の表面に沿うように形成されたカバー部材と、裏面に反射用凹凸形状が形成され、前記カバー部材の前面側に前記反射用凹凸形状が覆われるように取り付けられたプレート状の反射部材と、を備え、前記反射用凹凸形状は前記反射部材の表面に側方から傾斜して入射する入射光が十分な強さを有して再帰反射するように形成されていて、前記カバー部材は、自動車のライト光が前記反射部材の表面に側方から傾斜して入射し、かつ十分な強さを有して再帰反射するように取付手段を用いて前記路側構造物の表面に取り付けられ、そして、この取付手段は前記カバー部材の裏面と前記路側構造物の表面とを接着する接着手段である、ことを特徴とするものである。 更に、請求項２に記載の発明においては、前記カバー部材はプレート状に形成されていることを特徴とするものである。 更に、請求項３に記載の発明においては、前記カバー部材の前面は、前側一側端部から後側一側端部にかけてこのカバー部材の裏面側へ向かって傾斜していて、前記反射部材は前記カバー部材の前面に沿って取り付けられていることを特徴とするものである。 更に、請求項４に記載の発明においては、前記接着手段は、予め一方面が前記カバー部材の裏面に接着された両面接着テープであることを特徴とするものである。 As shown in FIGS. 8 and 9, this conventional gaze guidance mark has a configuration in which flat reflective elements 100 are mounted side by side on one surface of a double-sided tape 102, and the surface 101 of the reflective element 100 is a flat surface.
Therefore, the incident light r from the headlight of the automobile is reflected as r 1 on the surface of the reflective element 100 as shown in FIG. For this reason, when the light of a headlight is irradiated from an oblique direction, there is a problem that it is not used as a reflector. In addition, as shown in FIG. 10, when the gaze guidance mark is attached to the pole 103, when the light of the headlight of the automobile is irradiated from the direction of the arrow a, the retroreflected light is the portion indicated by the oblique lines. It is only from the reflective element 100, and the amount of light is not enough to attract attention. A similar problem occurs when it is attached to a guardrail.
As means for solving such problems, there are the following proposals.
The invention described in Japanese Patent Laid-Open No. 9-302631 is an invention according to claim 1 for the purpose of providing a gaze guidance mark whose installation cost is low and installation work is extremely simple. The cover member formed so that the back surface is along the surface of the roadside structure, and the uneven shape for reflection is formed on the back surface, and attached so that the uneven shape for reflection is covered on the front side of the cover member A reflection member having a plate shape, and the uneven shape for reflection is formed such that incident light incident on the surface of the reflection member with an inclination from the side is retroreflected with sufficient intensity. The cover member is attached to the surface of the roadside structure by using attachment means so that the light light of the automobile is incident on the surface of the reflection member with an inclination from the side and is retroreflected with sufficient strength. Attached to the surface, To, the attachment means is an adhesive means for bonding the surface of the back surface and the roadside structure of the cover member, it is characterized in. Furthermore, in the invention described in claim 2, the cover member is formed in a plate shape. Furthermore, in the invention described in claim 3, the front surface of the cover member is inclined from the front side one end to the rear side end toward the back side of the cover member, and the reflection member is It is attached along the front surface of the cover member. Furthermore, the invention according to claim 4 is characterized in that the bonding means is a double-sided adhesive tape having one surface bonded in advance to the back surface of the cover member.

しかし、上記特許文献１に記載の発明の場合、反射部材はその表面が平面形状となっているため、裏面の凹凸形状に多少の角度をつけたとしても、入射光の大部分は図９で説明したときと同じように、平滑な反射部材の表面で反射していまい、再帰反射光量は少なくなる。特に、図１０に示すように、ポール１０３等のような円形の表面に取り付けた場合の再帰反射光量は極端に減少する。
本発明は、斯る点に鑑みて提案されるものであって、その目的は、再帰反射光量を増大させることにより、運転者に注意を喚起することが可能な視線誘導標を提供することである。 However, in the case of the invention described in Patent Document 1, since the surface of the reflecting member has a flat shape, even if the unevenness on the back surface is slightly angled, most of the incident light is shown in FIG. As described above, the light is reflected off the surface of the smooth reflecting member, and the amount of retroreflected light is reduced. In particular, as shown in FIG. 10, the amount of retroreflected light when it is attached to a circular surface such as a pole 103 is extremely reduced.
This invention is proposed in view of such a point, The objective is to provide a gaze guidance mark which can call a driver | operator's attention by increasing the amount of retroreflection light. is there.

上記目的を達成するため、請求項１に記載の発明においては、視線誘導標において、両面テープの一面に反射素子を１列又は２列以上並べた構成の長尺体から成る視線誘導標において、前記反射素子の表面を断面円弧状に形成して成ることを特徴とするものである。   In order to achieve the above object, in the invention according to claim 1, in the line-of-sight guidance mark, in the line-of-sight guide mark comprising a long body having a configuration in which one or more rows of reflective elements are arranged on one surface of the double-sided tape, The surface of the reflecting element is formed in a circular arc shape in cross section.

更に、請求項２に記載の発明においては、請求項１に記載の反射素子の表面は、直線的な多面の連続から成る円弧状を呈していることを特徴とするものである。   Further, the invention described in claim 2 is characterized in that the surface of the reflecting element described in claim 1 has an arc shape formed of a continuous linear multi-face.

更に、請求項３に記載の発明においては、請求項１に記載の反射素子の表面は、小さな曲面の連続から成る円弧状を呈していることを特徴とするものである。   Furthermore, the invention described in claim 3 is characterized in that the surface of the reflecting element described in claim 1 has an arc shape formed of a continuous series of small curved surfaces.

更に、請求項４に記載の発明においては、請求項１に記載の反射素子内には、円弧状の表面に向けて放射状に傾斜した反射孔を形成して成ることを特徴とするものである。   Further, the invention described in claim 4 is characterized in that the reflecting element described in claim 1 is formed with reflecting holes that are radially inclined toward the arcuate surface. .

反射素子の表面の形状は、例えば、円弧状の曲面を呈しているため、入射光に対する反射素子の表面の角度は、直角及びこれに近い反射角度領域が拡大し、この分再帰反射光量が増大する。この結果、運転者に対する注意の喚起力は、従来のものに比較して２０〜３０％増大する。   The shape of the surface of the reflecting element is, for example, an arcuate curved surface, so that the angle of the surface of the reflecting element with respect to incident light is a right angle and a reflection angle region close thereto, and the amount of retroreflected light increases accordingly. To do. As a result, the alerting power for the driver is increased by 20 to 30% compared to the conventional one.

本発明は、反射素子の表面を断面円弧状に形成したことにより、再帰反射光量に加えて反応する反射素子の数も増大し、これにより、反射光量が増大し、運転者に大きな注意を喚起することができる。   In the present invention, since the surface of the reflective element is formed in an arc shape in cross section, the number of reflective elements that react in addition to the amount of retroreflected light also increases, thereby increasing the amount of reflected light and calling the driver a great deal of attention. can do.

以下、本発明に係る視線誘導標の形態例を図１〜図７に基づいて、詳細に紹介する。
図１は帯状に形成された視線誘導標全体の正面図、図２は平面図、図３は側面図、図４は斜視図、図５は反射素子の断面図、図６はポールに捲きつけるようにして取り付けられた本発明に係る視線誘導標の説明図、図７は円弧面の実施例の説明図である。 Hereinafter, the example of the form of the gaze guidance mark according to the present invention will be described in detail based on FIGS.
1 is a front view of the entire gaze guidance mark formed in a band shape, FIG. 2 is a plan view, FIG. 3 is a side view, FIG. 4 is a perspective view, FIG. 5 is a sectional view of a reflecting element, and FIG. FIG. 7 is an explanatory view of an embodiment of an arcuate surface.

この図１〜図７において、１は表面２が断面円弧状に形成されたかまぼこ型の反射素子であって、この反射素子１の裏面には、円弧面に対して放射状の角度となるように傾斜させた反射孔（反射ピン）３…が形成されていて、円弧状の表面２から入光した光は、この反射孔３…で反射し、再帰反射光となって表面２から出光する。
４は、一面に反射素子１を１列に並べて取り付けた両面テープであって、この両面テープ４の他面には、剥離紙５が貼り合わせてある。
上記実施例の視線誘導標を用いる場合には、図４に示すように、先ず必要な長さに両面テープ４をカットし、その上で剥離紙５を引き剥がし、この両面テープ４の貼着力を用いて図６に示すようにポール１０３に捲きつけるようにして取り付ける。 In FIG. 1 to FIG. 7, reference numeral 1 denotes a semi-cylindrical reflection element having a surface 2 formed in an arc shape in cross section, and the back surface of the reflection element 1 has a radial angle with respect to the arc surface. The inclined reflection holes (reflection pins) 3... Are formed, and the light incident from the arcuate surface 2 is reflected by the reflection holes 3 and exits from the surface 2 as retroreflected light.
Reference numeral 4 denotes a double-sided tape having the reflective elements 1 arranged in a line on one side, and a release paper 5 is bonded to the other side of the double-sided tape 4.
When using the line-of-sight guide in the above embodiment, as shown in FIG. 4, first, the double-sided tape 4 is cut to a required length, and then the release paper 5 is peeled off. And attach to the pole 103 as shown in FIG.

図５は入射光ｒと再帰反射光ｒ1を示し、入射光ｒが反射素子１に照射したときに、この入射光ｒは、反射素子１の表面２が円弧状に形成されているためと、内部の反射孔３…が放射状の角度を持っているため、再帰反射光ｒ1の角度が入射光ｒと同じ又は近くなり、よって、反射光量が多く、視認性が格段に良くなる。 FIG. 5 shows incident light r and retroreflected light r 1. When incident light r is applied to reflecting element 1, incident light r is formed because surface 2 of reflecting element 1 is formed in an arc shape. Since the internal reflection holes 3 have a radial angle, the angle of the retroreflected light r 1 is the same as or close to that of the incident light r, so that the amount of reflected light is large and the visibility is remarkably improved.

又、図６の斜線で示すように、入射方向ａに対し、反応する（反射する）反射素子１の数は、図１０に示した平板状の従来例に比較して、端に行くに従って、反射面の面積は減少するが、その数は倍増する。
なお、本実施例において、反射素子１は１列であるが、２列あるいはそれ以上の列構成としても良いことは勿論である。

The area of the reflective surface is reduced, but the number doubles.
In the present embodiment, the reflective elements 1 are in one row, but it is needless to say that the row configuration may be two or more.
7A to 7C show the deformation of the arc surface formed on the surface 2 of the reflecting element 1, (A) is a polyhedron composed of a continuous linear surface, and (B) is a polyhedron composed of a curved surface. (C) is an example in which multiple surfaces are formed on both sides, and all have the same reflection effect as the above-described embodiment.
