Description
本発明は、道路上やその周辺に設置され、ドライバーに対して道路の線形表示や視線誘導を促すための道路鋲に関するものである。 The present invention relates to a roadway installed on or around a road and for encouraging a driver to display the road linearly and guide the line of sight.
従来、道路鋲は、再帰性反射体を備え夜間の視線誘導を目的としたもの以外に、朝夕の薄暮時や昼間にも明瞭に視認できるように、道路鋲を蛍光顔料や蓄光顔料が配合された合成樹脂で成形し、道路鋲全体を蛍光顔料や蓄光顔料により発光させるものがある。しかしながら、蛍光顔料や蓄光顔料が配合された合成樹脂で道路鋲全体を成形すると、それ自体高価な蛍光顔料や蓄光顔料の使用量が多くなり、コスト高になる。 Conventionally, road fences have been combined with fluorescent pigments or phosphorescent pigments so that they can be clearly seen in the morning and evening twilight and in the daytime, in addition to those that have a retroreflector and are intended to guide the line of sight at night. Some of them are molded with synthetic resin, and the entire roadway is made to emit light with fluorescent pigments or phosphorescent pigments. However, if the entire roadway is molded with a synthetic resin in which a fluorescent pigment or a phosphorescent pigment is blended, the amount of expensive fluorescent pigment or phosphorescent pigment used per se increases and the cost increases.
この問題を解決するものとして、特許文献１には、蛍光顔料を含む透明樹脂カバーを道路鋲に被せるようにすることにより、蛍光顔料の使用量を少なくした道路鋲が開示されている。
すなわち、この道路鋲は、鋲本体に再帰性反射体が具備されている道路鋲であって、前記再帰性反射体の外面には蛍光顔料を含有する透明な樹脂層が設けられ、その樹脂層を樹脂カバーにより形成したものである。
As a solution to this problem, Patent Document 1 discloses a road fence in which the amount of fluorescent pigment used is reduced by covering the road fence with a transparent resin cover containing a fluorescent pigment.
In other words, this road fence is a road fence having a retro-reflector on the main body, and a transparent resin layer containing a fluorescent pigment is provided on the outer surface of the retro-reflector, and the resin layer Is formed by a resin cover.
しかしながら、上述の如き蛍光顔料を用いた道路鋲においては、再帰性反射体の外面に蛍光顔料を含有する透明な樹脂製カバーを被着するものであるため、道路鋲に樹脂製カバーを取付ける必要があり、製造工程が煩雑なものとなる懸念があった。 However, in the road fence using the fluorescent pigment as described above, a transparent resin cover containing the fluorescent pigment is attached to the outer surface of the retroreflector. Therefore, it is necessary to attach the resin cover to the road fence. There is a concern that the manufacturing process becomes complicated.
そこで本発明は上記の如き問題点を解消し、簡単に製造することができ視認性に優れる道路鋲を提供せんとするものである。 Therefore, the present invention is intended to solve the above problems and provide a roadway which can be easily manufactured and has excellent visibility.

本発明に係わる実施の形態について、図面に基づき以下に具体的に説明する。
すなわち、図１は本発明に係る道路鋲の実施の一形態を示す説明図であり、図２（イ）は図１の底面図であり、図２（ロ）は図１の縦断面図であり、図３は本発明に係る道路鋲の実施の他の形態を示す断面図である。
Embodiments according to the present invention will be specifically described below with reference to the drawings.
1 is an explanatory view showing an embodiment of a road fence according to the present invention, FIG. 2 (a) is a bottom view of FIG. 1, and FIG. 2 (b) is a longitudinal sectional view of FIG. FIG. 3 is a sectional view showing another embodiment of the road fence according to the present invention.
図１〜２において、道路鋲１０は、４つの傾斜した外側面と上面とを有する外殻部１と、外殻部１内側から縦横に格子状に垂下されたリブで形成されるリブ構造部２とを有し、相対向して位置する外殻部１の外側面には再帰性反射部２が取付けられ、両側からの車両の前照灯等の光を再帰反射できるようになされている。 1 and 2, a road fence 10 is a rib structure portion formed of four outer shells 1 having an inclined outer surface and an upper surface, and ribs suspended vertically and horizontally from the inner side of the outer shell 1 in a grid pattern. 2, and a retroreflecting portion 2 is attached to the outer surface of the outer shell portion 1 located opposite to each other so that light such as vehicle headlamps from both sides can be retroreflected. .
道路鋲１０の形成方法については、まず、リブ構造部２を蛍光顔料と蓄光顔料のいずれも含まない合成樹脂で射出成型等により成型し、次いでそのリブ構造部２を外殻部１を成型する金型に装着し、外殻部１を蛍光顔料又は蓄光顔料を含む合成樹脂でインサート成型することにより、外殻部１とリブ構造部２とを一体に形成するものである。 Regarding the method for forming the road fence 10, first, the rib structure part 2 is molded by injection molding or the like with a synthetic resin containing neither a fluorescent pigment nor a phosphorescent pigment, and then the outer shell part 1 is molded from the rib structure part 2. The outer shell portion 1 and the rib structure portion 2 are integrally formed by mounting on a mold and insert-molding the outer shell portion 1 with a synthetic resin containing a fluorescent pigment or a phosphorescent pigment.
かかる形成方法により道路鋲１０を形成することで、蛍光顔料又は蓄光顔料を含む合成樹脂で成形されるのは、設置されて外観に表れる外殻部１のみであって、外観に表れないリブ構造部２は蛍光顔料と蓄光顔料のいずれも含まない合成樹脂で成形されることから、蛍光顔料又は蓄光顔料の使用量は少なくて済み、製造コストを抑えることができると共に、蛍光顔料又は蓄光顔料が外殻部１から剥がれる等による視認性の低下を防ぐことができる。 By forming the road fence 10 by such a forming method, it is only the outer shell portion 1 that is installed and appears on the exterior, and is formed with a synthetic resin containing a fluorescent pigment or a phosphorescent pigment. Since part 2 is formed of a synthetic resin containing neither fluorescent pigments nor phosphorescent pigments, the amount of fluorescent pigments or phosphorescent pigments used can be reduced, manufacturing costs can be reduced, and fluorescent pigments or phosphorescent pigments can be used. It is possible to prevent a decrease in visibility due to peeling from the outer shell portion 1 or the like.
また、再帰性反射部３は、入射された光を高い効率で再帰反射できるものであって、本形態においては、外殻部１と別体で形成されたレンズ反射体を、超音波融着法等により外殻部１と一体化させているが、特に限定されたものではなく、多数の反射素子群を形成し、その反射素子群の裏面にアルミニウムのような金属の薄膜を金属蒸着法等により積層して反射性能を高めたプリズム状のものや、ガラスビーズやプリズム反射体を表面に配置した反射シート、合成樹脂製のシートにガラスビーズを埋設したもの等を適宜用いることができる。 Further, the retroreflective portion 3 can retroreflect incident light with high efficiency. In this embodiment, the lens reflector formed separately from the outer shell portion 1 is ultrasonically fused. Although it is integrated with the outer shell 1 by a method or the like, it is not particularly limited, and a large number of reflective element groups are formed, and a metal thin film such as aluminum is formed on the back surface of the reflective element group by a metal vapor deposition method. For example, a prism-like one that is laminated to improve the reflection performance, a reflection sheet in which glass beads and a prism reflector are arranged on the surface, a sheet in which glass beads are embedded in a synthetic resin sheet, and the like can be used as appropriate.
外殻部１の形成に用いられる合成樹脂は、特に限定されるものではないが、蛍光顔料又は蓄光顔料による発光を透過させると共に屋外使用に耐え得る耐候性を有する、例えばポリカーボネート、アクリル、ポリエチレンテレフタラートが特に好ましい。 The synthetic resin used for forming the outer shell portion 1 is not particularly limited. For example, polycarbonate, acrylic, polyethylene terephthalate having a weather resistance that transmits light emitted from a fluorescent pigment or a phosphorescent pigment and can withstand outdoor use is used. Talate is particularly preferred.
リブ構造部２の形成に用いられる合成樹脂は、外殻部１と一体に形成できるものであれば、特に限定されるものでなく、外殻部１に用いる合成樹脂の種類等を考慮して、適宜選択すればよい。 The synthetic resin used for forming the rib structure portion 2 is not particularly limited as long as it can be formed integrally with the outer shell portion 1, and in consideration of the type of synthetic resin used for the outer shell portion 1. It may be selected as appropriate.
次に、図３の形態について説明する。道路鋲１０は、４つの傾斜した外側面と上面とを有する外殻部１を備え、相対向して位置する外殻部１の外側面には再帰性反射部３が取付けられている。また、外殻部１の内側は空洞となされており、その空洞に充填材４が充填されている。 Next, the form of FIG. 3 will be described. The road fence 10 includes an outer shell portion 1 having four inclined outer surfaces and an upper surface, and a retroreflecting portion 3 is attached to the outer surfaces of the outer shell portions 1 located opposite to each other. Further, the inside of the outer shell portion 1 is formed as a cavity, and the filler 4 is filled in the cavity.
そして、再帰性反射部３を除く外殻部１の外側面には、蛍光塗装、蓄光塗装又は蛍光フィルムの貼着による処理５が施されている。 The outer surface of the outer shell portion 1 excluding the retroreflecting portion 3 is subjected to treatment 5 by fluorescent coating, phosphorescent coating, or fluorescent film sticking.
かかる構成の道路鋲となすことにより、カバー材等の別部材を必要とすることなしに、視認性に優れる道路鋲を簡単に製造することができる。 By using the road fence having such a configuration, a road fence with excellent visibility can be easily manufactured without requiring a separate member such as a cover material.
前記道路鋲１０において、外殻部１を形成する材料は、図１〜２に示す形態のように、蛍光顔料や蓄光顔料を配合するものでないので、任意の合成樹脂材料が使用でき、又充填材４は外殻部１の強度確保を図るものであるので、使用される充填材４は特に限定されるものではないが、強度確保のため硬質である必要があり、二液硬化型のエポキシ樹脂が一般に使用される。 In the road fence 10, the material forming the outer shell portion 1 does not contain a fluorescent pigment or a phosphorescent pigment as shown in FIGS. 1 and 2, so any synthetic resin material can be used and filled. Since the material 4 is intended to ensure the strength of the outer shell portion 1, the filler 4 used is not particularly limited, but must be hard to ensure the strength, and is a two-component curable epoxy. Resins are generally used.
本発明に係る道路鋲は、外殻部内側から垂下されたリブで形成されるリブ構造部を有し、外殻部を蛍光顔料又は蓄光顔料を含む合成樹脂で成形し、リブ構造部は蛍光顔料と蓄光顔料のいずれも含まない合成樹脂で成形すると共に、外殻部とリブ構造部とを一体に形成しているので、蛍光顔料又は蓄光顔料の使用量は少なくて済み、製造コストを抑えることができ、又外殻部を蛍光顔料又は蓄光顔料を含む合成樹脂で成形するので、蛍光顔料又は蓄光顔料が外殻部から剥がれる等による視認性の低下を防ぐことができる道路鋲として好適に利用することができる。 The road fence according to the present invention has a rib structure part formed by ribs suspended from the inner side of the outer shell part, the outer shell part is molded with a synthetic resin containing a fluorescent pigment or a phosphorescent pigment, and the rib structure part is fluorescent. Molded with a synthetic resin that contains neither pigments nor phosphorescent pigments, and the outer shell and rib structure are integrally formed, so less fluorescent pigments or phosphorescent pigments are used, reducing manufacturing costs In addition, the outer shell portion is formed of a synthetic resin containing a fluorescent pigment or a phosphorescent pigment, so that it is suitable as a road fence that can prevent a decrease in visibility due to the fluorescent pigment or the phosphorescent pigment peeling off from the outer shell portion. Can be used.
