【０００１】
【発明の属する技術分野】
本発明は、道路のセンターライン、歩車道分離、ゼブラゾーンなどに利用される再帰反射レンズ付き視線誘導標識柱に関するものである。
【０００２】
【従来の技術】
前記の如き再帰反射レンズ付き視線誘導標識柱には特許第１５０２４９３号（特開昭５９−１６５７０９号参照）がある。この従来技術は、再帰反射レンズをプラスチックからなるホルダーに装着し、ベースの成型に際しそのホルダーをベースと一体に溶着するものであって、再帰反射レンズをベースと強固に取り付けることはできるが、再帰反射レンズの材質として耐熱材（無機ガラス材）しか使用できないばかりでなく、ホルダーに装着した再帰反射レンズをベースの成形型に装着して溶着成形法により固定しなければならないので、製作工程が多く、生産性が悪いという不具合がある。
【０００３】
また、実開平３−１２２１１１号公報、特開平４−１０５１１４号公報には、組立て方式により視線誘導標識柱を製作することが記載されているが、この従来例ではベース部分に再帰反射機能を付与することができない。なお、市販されている視線誘導標識柱には、ベース部分に反射機能を付与している製品もあるが、このものは、ベースに反射材をビス止めなどにより固定しているため、車輌の踏み付けなどにより反射材が脱落しやすく、かつ、ビスがタイヤに損傷を与えたりする危険がある。
【０００４】
【発明が解決しようとする課題】
本発明は、前記の如き従来技術の問題点を改善し、組立て方式によりベース部分に再帰反射レンズを組付けることができ、しかも、その組付けは極めて強固であって、タンクローリーなどの大型車輌により踏み付けられても脱落するおそれがない再帰反射レンズ付き視線誘導標識柱を提供することを目的とする。
【０００５】
【課題を解決するための手段】
前記の目的を達成するため、本発明は、下端にコア台座を一体に形成せしめると共にそのコア台座から下方に向ってボルトを突設した標識柱本体と、該標識柱本体のコア台座の外周に嵌合してコア台座をとり囲むと共にその中央に起立部を形成させたベースと、前記コア台座の底面からベースの底面にかけて当接する底面プレートと、露出部とそれより大径の反対面を有する基部とを段部を介して一体に結合された再帰反射レンズとよりなり、
前記コア台座とベースとの嵌合面を上方に向って縮径するテーパ面となし、かつ、該ベースの前記起立部に前記再帰反射レンズの露出部のみを挿入し得る貫通孔を設け、その貫通孔に再帰反射レンズの露出部を挿入してその先端をベースから露出させると共に前記段部を前記ベースの起立部の内面に当接させ、この状態でベースの下方からコア台座をベース中に嵌合してコア台座の外面とベースの内面との間に再帰反射レンズの基部を挟着保持すると共に、その挟着保持状態を前記コア台座から突出されボルトに装着した底面プレートとボルトに螺着したナットとにより維持すべくなしたことを特徴とする。
【０００６】
本発明の再帰反射レンズ付き視線誘導標識柱は、前記の如く、下端にコア台座を一体に形成させた標識柱本体と、該標識柱本体のコア台座の外周に嵌合してコア台座をとり囲むベースと、前記コア台座の底面からベースの底面にかけて当接する底面プレートと、露出部とそれにより大径の反射面を有する基部とを段部を介して一体に結合された再帰反射レンズとよりなり、前記コア台座とベースとの嵌合面を上方に向って縮径するテーパ面となし、かつ、該ベースに前記再帰反射レンズの露出部のみを挿入し得る貫通孔を設け、その貫通孔に再帰反射レンズの露出部を挿入してその先端をベースから露出させると共に前記段部を前記ベースの起立部の内面に当接させ、この状態でベースの下方からコア台座をベース中に嵌合してコア台座の外面とベースの内面との間に再帰反射レンズの基部を挟着保持すると共に、その挟着保持状態を前記コア台座から突出されたボルトに螺合したナットの締付けにより維持すべくなしたので、ビスを全く使用しない組立て方式によりベース部分に再帰反射レンズを組付けすることができ、しかも、その組付けは極めて強固であって、大型車輌により踏み付けられても脱落するおそれがないので、車輌により頻繁に踏み付けられる可能性があるセンターラインへの設置も可能な再帰反射レンズ付き視線誘導標識柱を提供することができる。
【０００７】
【発明の実施の形態】
以下、添付図面について本発明の再帰反射レンズ付き視線誘導標識柱の実施の形態を説明する。
図１は、本発明にかかる再帰反射レンズ付き視線誘導標識柱の各構成部材を分解して示す説明図であって、図中（Ａ）に示すコア台座付き標識柱本体１−１と同（Ｂ）に示すベース１−２と、同（Ｃ）に示す再帰反射レンズ１−３と、同（Ｄ）に示す底面プレート１−４とから構成されている。
【０００８】
前記コア台座付き標識柱本体は、硬度Ａ８０〜９５、好ましくはＡ８５のウレタンパイプからなるパイプ本体１−１−３に反射シート１−１−２を貼着し、頭部１−１−１は発泡ポリウレタンで硬度Ｃ４０〜８０、好ましくはＣ６０を注型成形法によりパイプ本体１−１−３と一体化させる。この頭部付きパイプ本体の下端には、硬度Ａ８０〜９５、好ましくはＡ９０の注型ウレタン材により上方が縮径されたテーパ面１−１−７を有するコア台座１−１−５を注型成型法によりパイプ本体と一体に成型すると共に、そのコア台座１−１−５の成型に際し、パイプ本体１−１−３の補強本１−１−４と、コア台座より下方に向けて突出するボルト１−１−６と埋設設置する。
【０００９】
図１（Ｂ）に示すベース１−２は、硬度Ｄ３５〜７０、好ましくはＤ６４の射出成形用ウレタン材から構成され、前記標識柱本体のコア台座１−１−５の外周のテーパ面に嵌合してコア台座をとり囲むと共に、その中央に起立部１−２−３を形成し、かつ、その起立部に再帰反射レンズの露出部１−３−１を内側から挿入し得る貫通孔１−２−２を任意所要数形成する。
【００１０】
図１（Ｃ）に示す再帰反射レンズ１−３は、通称キャッアイと呼ばれるガラスや透明プラスチックなどにより成型された高輝度再帰反射レンズであって、ほぼ半球状をなす露出部１−３−１と、それにより大径の基部１−３−３とが段部１−３−２を介して一体に結合され、基部１−３−３の背面に金属箔などの反射面１−３−４が設けられている。なお、本発明に使用する再帰反射レンズは、特許第１５０２４９３号のようにベースと一体に溶着するものではないので、有機ガラス（ＭＭＡ材）、透明プラスチックなどの比較的耐熱性が劣る材質のものを使用することができ、これにより、射出成型が可能となって、安価で寸法精度の高い再帰反射レンズを使用することができる。
【００１１】
図１（Ｄ）に示す底面プレート１−４は、前記ベース１−２−１の底面から前記コア台座１−１−５の底面にかけて当接されるように中央部が隆起した形状をなし、その中央部に前記コア台座１−１−５から下方に向けて突出されたボルト１−１−６の挿通孔１−４−１が形式されている。
【００１２】
図２は、再帰反射レンズ１−３をコア台座付き標識柱本体１−１とベース１−２とにより挟着して組付けた状態を示す断面図であって、再帰反射レンズ１−３の露出部１−３−１をベース１−２の内側から貫通孔１−２−２中に圧入して（必要に応じ再帰反射レンズの露出部１−３−１の外径より貫通孔１−２−２の円径をやや小さくしておく）露出部１−３−１をベース１−２の長面から露出させておき、次いでベース１−２の底面側からコア台座付き標識柱本体１−１を挿入する。すると、コア台座１−１−５とベース１−２との嵌合面には上方に向って縮径するテーパ面となっているので、再帰反射レンズ１−３はコア台座１−１−５によって外方に押され、再帰反射レンズの段部１−３−２がベース１−２の内面に当接すると共にコア台座の表面が再帰反射レンズの背面を押圧した状態、すなわち、再帰反射レンズをベース１−２とコア台座１−１−５との間に挟着してた状態で組み付けることができ、この状態で、底面プレート１−４のボルト装着孔１−４−１をボルト１−１−６に合わせて底面プレート１−４をコア台座１−１−５とベース１−２の底面に当て、ウレタン平ワッシャ１−１−８を介しナット１−１−９をボルト１−１−６に締め付けて再帰反射レンズをベースに強固に組み付ける。
【００１３】
前記図２に示す実施態様は、ベースの底面に接着剤を塗布して路面上に接着固定するタイプの再帰反射レンズ付き視線誘導標識柱に本発明を適用した例を示すもので、図３はその製品の一例を示す外観図である。
【００１４】
図４は、路面中に埋設した埋設用脚に着脱自在にネジ止めできるようにしたタイプの再帰反射レンズ付き視線誘導標識柱に本発明を適用した例を示す図２と同様の断面図であって、ベース１−２の周縁部に固定用のボルト挿通孔１−２−４およびその頭部受座１−２−５を設けた点が異なるだけで、その他の構成は図２と同様であるので、その詳細な説明は省略する。また、このタイプの視線誘導標識柱の固定構造は例えば図５に示すとおりであるが、この構造も周知であるので、その詳細な説明は省略する。図６はこのタイプの製品の一例を示す外観図である。
【００１５】
【発明の効果】
以上に述べたように、本発明によれば、視線誘導標識柱のベース部分にビス留めや溶着法によらない組立て方式により再帰反射レンズを組み付けることができ、しかもその組付けは、大型車輌により踏み付けられても脱落するおそれがない強固なものとすることができる効果がある。
