Description

[Detailed explanation of the invention] <Industrial application field> This invention is related to road signs at night, and uses the reflection from lights emitted by cars to confirm road conditions, thereby improving safe driving. Concerning the development of reflectors for use as signs.

<Prior Art> Conventionally, road signs of this kind have been installed in various places, but they need to be displayed in various forms depending on the purpose of use and location. As a result, there were many different types, and it was not possible to manufacture them economically.

<Problems that the invention attempts to solve> (1) From the above, the first thing to do is to produce it economically.

(2) The manufactured reflector must be suitable for the location where it will be used.

(3) Ensuring that appropriate signs are available depending on the road conditions at the site.

<Means for solving the problem> Based on the above, as shown in an example of implementation, the present invention uses a flexible synthetic resin such as transparent polycarbonate with a prism collective reflection surface 1 provided on the inner surface. First, a reflection band 2 of a constant width is provided. The back surface of the reflective band is provided with notched grooves 3 of a predetermined angle, for example, 30 degrees, at equal intervals, and the width between the notched grooves is divided into one reflective plate 4. If this is made into a circle as shown in Figure 4, the notch groove 3 will have a notch angle of 30 degrees at 11 places, and if the notch grooves at both ends are each 15 degrees, the total notch will be 360 degrees. The groove becomes circular and is reflected on the entire circumference. Therefore, the reflector 4 for one surface is formed in an arc shape as shown in FIG. 2, and the width of the reflector may be changed depending on the diameter of the arc surface or the size of the radius.

When connecting the reflective bands 2 in the vertical direction, cut portions 5 are provided at both ends in the longitudinal direction, and the cut portions are aligned and bonded with an appropriate adhesive as shown in FIG. In addition, Fig. 6A shows a U-shaped reflective cutout groove that uses two reflecting plates 4 on two sides to form a mountain shape in two directions, and B uses three sides to reflect in three directions: the front, left and right sides. It can be freely obtained by molding separately from part 3. It goes without saying that the angle of the notched groove 3 may be changed depending on the number and shape of the reflecting plate 4 used.

<Effects of the invention> The present invention is a strip-shaped reflector as described above, and since the material is flexible polycarbonate, it is very convenient because it can be divided and used in a variety of ways depending on its location and installation method. This also has the effect of making it economical to manufacture.
