REFLECTION MEMBER FOR PROTECTIVE FENCE COLUMN
PROBLEM TO BE SOLVED: To provide a reflection member for a protective fence column, for reducing manufacturing cost, easily fittable in a column by manpower without using a tool, without risk of damaging fitting to the column, reducing influence imparted to a person even when striking on the person by scattering by damaging by a collision accident of a vehicle to a protective fence, and having the further high light reflection effect.SOLUTION: In a reflection member for a protective fence column composed of a cylindrical reflection member body 3 fitted in a cap of a column 1 with the cap of a protective fence, a plurality of claws formed toward the inside on the lower edge of the reflection member body 3 and a light reflection material 5 provided on a side surface of the reflection member body 3, in which a cover-shaped abutting part 6 for abutting on an outer surface of the cap is formed in an upper part of the reflection member body 3, and a diameter of a circle of connecting a tip part of the claw before fitting in the reflection member body 3, is smaller than a diameter of an outer peripheral surface of the cap, and when fitting the reflection member body in the cap, the claw expands outward against elastic force, and is restored to an original state by the elastic force after completing fitting-in, a light reflection surface 7 is formed in the abutting part 6.SELECTED DRAWING: Figure 1
【課題】製造コストが安く、工具等を使わず人手により容易に支柱に嵌め込むことができ、支柱に対して嵌め込み損じるおそれがなく、しかも、防護柵への車の衝突事故等により破損して飛散し、人に当たった場合であっても人に与える影響が少なく、しかも、さらに高い光反射効果を有する防護柵支柱用反射部材を提供する。【解決手段】防護柵のキャップ付き支柱１のキャップに嵌め込まれる、円筒形状の反射部材本体３と、反射部材本体３の下縁に内側に向けて形成された複数個の爪と、反射部材本体３の側面に設けられた光反射材５とからなり、反射部材本体３の上部には、前記キャップの外面に当接する蓋状の当接部６が形成され、反射部材本体３の嵌め込み前の前記爪の先端部を結ぶ円の直径は、前記キャップの外周面の直径より小さく、前記反射部材本体を前記キャップに嵌め込む際には、前記爪は、弾性力に抗して外方に広がり、嵌め込みが完了した後は、弾性力により元の状態に復帰する防護柵支柱用反射部材において、当接部６には、光反射面７が形成されている。【選択図】図１
