Title: Inclinable glance guidance mark post
Inventor: KURIHARA NORIMASA
IPC: E01F9/588
Filed: 1994-12-06
Abstract: PURPOSE: To prevent the occurrence of discoloration or fade of color caused by UV rays by constituting the wall of a pole with an inner layer and an outer layer which comprise different types of polyurethane-based thermal plastic elastomer and mounting a reflective mark which comprises a retroreflective sheet and fluorescent paint, on the surface of the outer layer. CONSTITUTION: An inner layer 13 and an outer layer 14 which constitute the wall of a pole, are arranged to be made of different types of polyurethane-based thermoplastic elastomer, thereby varying an index of refraction against ultraviolet rays. Furthermore, a non-yellow change polyurethane-based elastomer is applied to the outer layer 14 so as to prevent the change of color. Even when a light color-based color tone, such as blue or yellow, is given to the outer layer 14, the UV rays are arranged not to reach the inner layer 13 substantially, thereby protecting the color tone of the pole 10 from changed color or faded color for a long time.  In addition, the outer layer 14 of the pole 10 is arranged to be transparent or semi-transparent to visible light so that the light may be penetrated and directed at the inner layer, thereby recognizing the color the inner layer 13 with a reflective light from a mixed pigment coated on the inner layer 13. At night, when light strikes on the reflexive mark 12, fluorescent light is produced or the light is retro-reflected, thereby enabling the light to be recognized.
