Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a road sign board in which a road sign can be correctly recognized even in a backlight.

[0002]

[Prior art]

 Conventionally, road sign boards that are generally installed are those in which characters and figures are written on a metal plate with fluorescent paint.

[0003]

[Problems to be solved by the invention]

 Drivers traveling in the direction of the sun on a sunny day before sunrise or sunset can see characters and figures on the road sign in black because the back light of the sun makes it difficult to see the characters and figures on the road sign. This makes it difficult to check the image, which is a cause of traffic rule violations and accidents.

[0004]

[Means for Solving the Problems]

 In view of these points, the inventor has arrived at the present invention as a result of repeated trial production research, and the present invention is to make the characters or figures on the front surface brighter using sunlight shining from the back side of the sign board. This makes characters or figures appear brighter and easier to confirm.

[0005]

[Embodiment of the invention]

 The embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a front plate of a sign board, which is a stop sign board often seen on a road, which is painted red as a whole and “stop” in white. However, in the present invention, this character portion is cut out.

FIG. 2 shows a rear plate provided with a large number of through holes for daylighting, and the through holes are provided so as not to coincide with cutouts of characters on the front plate.

FIG. 3 is a central sectional view of the sign board, and shows a configuration in which a transparent plate is provided in a sandwich shape between the front plate and the back plate of FIGS. 1 and 2.

[0008]

【Example】

 In the figure, (1) is a front view of the surface plate, and the surface plate (1) of the stop sign shown in the figure is painted with red fluorescent paint, and the character (4) of "stop" is cut out at the center and displayed. Have been.

FIG. 2 is a front view of the back plate (2), in which a large number of lighting holes (5) are provided at positions not overlapping the cutout characters (4) of the front plate (1).

FIG. 3 is a central sectional view of the sign board, in which a transparent plate (3) for passing sunlight is sandwiched between a front plate (1) and a back plate (2). The transparent plate (3) is further formed so that the joining end thereof is formed obliquely toward the rear and joined so that at least a large amount of light can be obtained.

Therefore, not only is the front plate (1) slightly larger than the rear plate (2), but also the bonding surface of the rear plate (2) is preferably white.

Since the road sign board of the present invention has the above-described configuration, the solar light S impinging from behind the sign board enters through the through-hole (5) of the back board (2) and passes through the transparent board (3). The character (4) appears in the cut-out portion of the character (4), and the light is also incident from the joint end, so that the expression of the character (4) can be further brightened.

[0013]

[Effect of the invention]

 The road sign board of the present invention can accurately identify the sign by displaying only characters or figures brightly even in the case of back light, so it can be transmitted accurately without misunderstanding the sign at sunrise or sunset. Violations and accidents can be prevented before they occur.
