Description
【０００１】
【発明の属する技術分野】
本発明は、車道のセンターライン、斜線変更線、分離帯などに利用される道路標識柱に関するものである。
【０００２】
【従来の技術】
近年、車輌が接触したときに弾性変形する中空の可倒式道路標識柱が高速道路から一般道路にわたって広く利用されている。これは、視認性が高く、標識柱本体が弾性を有することから、運転者などの安全性が確保されること、取り付けあるいは施工が簡単なことなどによる。
【０００３】
ところで、この種の道路標識柱においては、夜間走行中のドライバーなどの視認性を高めるため、標識柱本体に反射材や蛍光材などが取り付けられている。
【０００４】
図３はその最も簡単な例を示すもので、標識柱本体１に反射材３が直接貼り付けられている。なお、図において、２は路面設置用のベースである。しかし、図３のような構成の道路標識柱は、車輌等の衝突により反射材３が破損したり剥がれたりしやすいという問題がある。
【０００５】
上記のような問題を解決するため、図４に示すように、透明な保護テープ４を反射材３の上に貼り付けたものや、図５に示すように、本体１の外周に溝５を形成し、その溝５中に反射材３を貼り付けて反射材を保護するように構成したものが知られている。しかし、このようにしても、車輌などとの衝突により反射材や蛍光材が破損するケースがある。
【０００６】
さらに、上記のような問題を解決するため、反射材を内層と外層との間にサンドイッチした状態で標識柱本体を成形することが特許第２５６２５６６号により提案されている。
【０００７】
【発明が解決しようとする課題】
上記特許第２５６２５６６号の方法によれば、反射材や蛍光材などを確実に保護することはできるが、内層と外層との間に反射材や蛍光材をサンドイッチした状態で一体成形するため、製造方法が複雑で、コスト高になるという問題がある。
【０００８】
本発明は、上記のような問題点を改善し、反射材や蛍光材が破損し難く、かつ、安価に製作可能な道路標識柱を提供せんとするものである。
【０００９】
【課題を解決するための手段】
本発明は、前記の目的を達成するため、標識柱本体に、反射材ないし蛍光材を取り付けるための溝を深さ方向に複数段形成し、かつ、その最深段の溝に反射材ないし蛍光材を取り付けたことを特徴とする。
【００１０】
また、本発明は、標識柱本体に、反射材ないし蛍光材が取り付けられる道路標識柱において、標識柱本体に、反射材ないし蛍光材を取り付けるための溝を深さ方向に複数段形成し、かつ、その最深段の溝に反射材ないし蛍光材を取り付けると共に、その最深段の溝より表面側の溝に透明ないし半透明の保護部材を取り付けたことを特徴とする。
【００１１】
さらに、本発明は、前記の複数段に形成された溝の外周に該溝を取り囲む突起を形成させたことを特徴とする。
【００１２】
本発明は、前記の如く、標識柱本体に、反射材ないし蛍光材を取り付けるための溝を深さ方向に複数段形成し、かつ、その最深段の溝に反射材ないし蛍光材を取り付けたので、車輌等が衝突した際、最深段に取り付けられた反射材ないし蛍光材が車輌等と接触しようとするのを表面側の溝が阻害して反射材や蛍光材が破損されにくいようにすることができる。
【００１３】
また、最深段の溝より表面側の溝に透明ないし半透明の保護部材を取り付けると、前記の作用・効果と共に、透明ないし半透明の保護部材による保護効果が加わって反射材や蛍光材がさらに破損し難いようにすることができる。
【００１４】
さらに、複数段に構成された溝の外周に突起を形成するとその突起が車輌などと反射材や蛍光材とが接触しようとするのを阻害して、反射材や蛍光材の破損を一層低減することができる。
【００１５】
【発明の実施の形態】
以下、添付図面について本発明の実施の形態を説明する。
図１は本発明の第１の実施形態であって、１は標識柱本体を示し、下記物性を有するウレタンにより構成した。
