Field of the Invention The present invention relates to a road sign installed on a road in an east-west direction, in which a translucent milky white reinforced plastic plate is provided from the back against the reverse rays of the morning sun and the west sun. Absorbs light, passes through a frame with a certain width or more, and passes through letters, arrows, and symbols where transparent reflective material is adhered to a transparent reinforced plastic plate on the signage surface. Are structures that can be clearly recognized. 2. Description of the Related Art A conventional road sign board has a certain sign when the morning sun and the west sun are behind the sign surface because the sign surface becomes black when viewed with the naked eye and the marked contents cannot be recognized. In the time zone of, the role as a sign cannot be fulfilled. [0003] Therefore, a sign installed on a road running in the east-west direction, which is presently invisible to a driver who has been driving for a certain period of time, is a great hindrance to road traffic. It was invented in order to respond to the improvement of road traffic safety by being able to see well in this backlight. According to the present invention, the recognition of a sign surface is improved by the following configuration. (B) Two types of reflectors are adhered to the transparent reinforced plastic plate (1) on the marking surface. (B) Translucent milky white reinforced plastic plate on the back (3)
Is installed. (C) A frame (4) is provided between the transparent reinforced plastic plate (1) on the marking surface and the translucent milky white reinforced plastic plate (3) on the back surface so as to have a certain distance or more. That is,
According to the present invention, a reflective material is adhered to a transparent reinforced plastic plate to form a sign surface, and a translucent milky white reinforced plastic plate capable of dispersing and transmitting a light beam is installed behind the transparent reinforced plastic plate, A plastic plate and the translucent milky white reinforced plastic plate are installed at a predetermined interval in a frame, and the translucent milky white reinforced plastic plate is
It has a reinforcing frame on its back . DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described. In the conventional sign, the sun rays from behind the sign surface strongly hit the driver's eyes while driving the car, and the sign surface is black. Appearance characters, arrows, and symbols are almost unrecognizable. Therefore, the light beam is conversely used, and when the light beam can pass through the translucent milky white reinforced plastic plate (3) on the rear surface, the light beam is dispersed and the transparent reinforced plastic plate (1) on the sign surface is dispersed. ) Are transmitted through the reflector (2)-for characters, arrows and symbols, which are adhered to the characters, arrows and symbols while reducing the light rays, and transmitted to the driver during driving. In addition, the translucent milky white reinforced plastic plate (3) on the back side is dispersed when the light beam passes, so that even if there is a structural skeleton for reinforcement necessary on the back side, it does not shadow the light source because it becomes a shadow. . Therefore, a large road sign with a large sign area can be manufactured. As described above, by arranging the translucent milky white reinforced plastic plate which disperses and transmits the reverse light behind the sign surface, the light can be effectively dispersed and transmitted. By installing the road sign manufactured in this configuration on an east-west road, it is possible to improve the safety of the driver who is driving a car and the provision of necessary information. Further, since the translucent milky white reinforced plastic plate has a reinforcing frame on the back surface, a large road sign with a large marking area can be manufactured.
