Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of the structure of a road reflective sign, and particularly refers to a main body made of a colorless and transparent reinforced glass, the upper side of which is a hemisphere and the lower side of which is a cylindrical body. A transparent colored thin film is provided on the periphery of the bottom surface of the cylindrical body, and then a metal reflective layer is applied to the outer side of the transparent colored thin film. Since it can be plated, it not only increases the light reflection intensity, but also improves corrosion resistance and extends its life.

[0002]

[Prior art]

 The "reflective sign for road" has a substantial and necessary function for road separation, and the effect of the reflection that it achieves is a safety facility that alerts the driver to the road condition. The "reflective sign for use" is extremely important, and the influence of the superiority or inferiority of the reflective effect is also large.

A conventional road reflection sign is made by spraying a reflection layer B of aluminum or aluminum alloy on the bottom portion A of green transparent tempered glass by a plating method (see FIGS. 1 and 2).

[0004]

[Problems to be solved by the device]

 It has properties such as high strength, abrasion resistance, resistance to aging, and good weather resistance, but it is colored on the whole clear tempered glass, and its bottom is plated with a reflection layer of aluminum or aluminum alloy. Therefore, if you want to change the color, you have to change the color of the glass, which makes it impossible to meet the diverse needs of customers and increases problems for the vendor.

Referring to FIGS. 3 and 4, another road reflective sign has two plastic reflectors D put in a hollow glass C, and a resin layer E is further filled inside the hollow glass C. However, since its reflection angle is only 180 ° and its reflection area is small, the portion protruding from the road surface becomes large, and when a car passes through the road sign, large fluctuations occur.

[0006]

[Means for Solving the Problems]

 The main object of the present invention is to provide a road reflective sign with extremely good reflection strength, which is provided with a transparent colored thin film on the lower side of the main body made of colorless transparent tempered glass, and A metal reflective film is coated on the outer side of the transparent colored thin film, which has the characteristic that it can meet various requirements in addition to obtaining better reflection intensity.

Another object of the present invention is to provide a road reflective sign having a colored layer, a metal reflective layer and an anticorrosion layer coated on the underside of the body, which is highly corrosion resistant. It has the characteristic that its service life is extended. Still another object of the present invention is to provide a reflective sign for a road in which the coating method of the colored layer can be changed according to the actual demand, and the colored layer is a single color, or two halves of each color, or two parts of the metal reflective layer. With only 1 applied, a reflection angle of 360 ° or 180 ° can be achieved, and depending on the construction road (one-way, two-way or curved road), the best reflection effect is exhibited. It has characteristics.

【Example】

 Referring to FIG. 5, the present invention has a body 1 made of colorless and transparent tempered glass, the body 1 has a hemisphere 11 on the upper side, and the hemisphere 11 on the lower side is connected to the hemisphere 11. A cylindrical body 12 is provided, and a transparent colored thin film 2 is applied to the bottom peripheral edge of the cylindrical body 12, and the transparent colored thin film 2 has the same expansion coefficient as that of the main body 1. Yellow, red, or other The transparent glass, which is the color specified by the traffic regulations, can be used as an alternative, and the application method can be designed to be a single color or two-color halves 21 and 22 according to actual needs (Fig. 6). (See also together), so that it is formed in two colors with different directions, but if it is used for a one-way road, a transparent colored thin film is formed on one half of the periphery of the cylindrical body 12. 2 may be applied. A metal reflective layer 3 is coated on the outer side of the transparent colored thin film 2, and only half of the metal reflective layer 3 can be coated, whereby only half is reflected and half is not reflected. And a corrosion-resistant layer 4 can be plated on the outside of the metal reflection layer 3, and the corrosion-resistant layer 4 has a fluorine resin coating, an epoxy resin coating with good weather resistance, Even if the main body 1 of the road reflective sign is installed in a special environment (for example, an industrial park), a metal reflective layer 3 (aluminum, aluminum, The aluminum alloy, stainless steel, or titanium) is prevented from corroding to the outside, and the anticorrosion layer 4 covers the metal reflection layer 3 in a completely sealed manner.

Next, referring to FIG. 7, when the incident light rays 51 and 52 enter the upper hemisphere 11 of the main body 1, they are refracted and applied to the lower cylinder 12 to form a metal reflection layer. 3, the metal reflection layer 3 reflects the incident light rays 51 and 52, and the reflected light rays 51 ′ and 52 ′ are also refracted by the hemisphere 11, so that the reflection angle is large and the reflection strength is strong. A reflective sign for the road can be obtained.

As shown in FIG. 8, the cylindrical body 12 on the lower side of the main body 1 may be embedded in the ground 6 to expose only the hemisphere 11 and the upper end 121 of the cylindrical body 12.

[Effect of device]

 To summarize the above, the present invention is indeed an excellent road reflective sign, and its advantages will be explained here. 1. Respond to financial effects. Since it reflects color with a transparent colored thin film, it is not necessary to color all road reflective markings, that is, it has different combinations of variations, so it can meet various requirements. Moreover, since the transparent colored thin film is bonded between the body of the tempered glass and the metal reflective layer, the transparent colored thin film may fall off or be peeled off by the tire or under the influence of the sun or rainwater weather factors. Never.

2. The useful life can be effectively extended. Since the corrosion resistant layer is plated on the bottom side, it is possible to prevent corrosion caused by the metal reflective layer being buried in the ground for a long period of time and to secure the reflective effect. 3. It has characteristics such as high strength, wear resistance and maintenance. Since the present invention is made of tempered glass, it does not easily attach dust, does not break even if hit by a large vehicle, and has good safety.

[0013] 4. It can be used according to various road conditions. The metal reflective layer can be applied to the whole or only the lower half and is subject to a 360 ° or 180 ° reflection selection and has a wide range of applications.
