Description

Road Sign {Road Eye}

The present invention relates to a road marker, and is excellent in durability and weatherability, so that the reflector and the phosphorescent material are not discolored or detached even in an external impact, and the convex lens is placed on the reflector surface to increase the reflex reflection brightness. Road pedestrians and drivers can clearly identify road signs.

In order to mount a conventional road marker on the surface of a road, a hole is firstly formed in the road, and a road sign is installed by inserting an anchor attached to the pole of the road marker into the hole.

Conventional road signs consist of a die-cast material to withstand the impact of the vehicle. As the road markers are made of diecast material, friction with the wheels of the vehicle does not occur so much that the wheels slip from the top surface of the road markers. In order to overcome such a problem, the conventional road markers have a height as high as 3 to 5 cm. As soon as a vehicle crashes into a highly configured road mark, the impact is transmitted to the driver, so the driver recognizes that he is in a lane equipped with a road sign.

However, a strong momentary shock caused by a vehicle passing over a high-level conventional road sign makes the novice driver feel uneasy, and there is a risk of a secondary accident as a sudden turn to avoid a road sign. It is also concerned about the damage of the wheel due to impact. As described above, the conventional road markers are configured to recognize the driver by shocking the vehicle, which poses a risk of secondary accident.

In addition, in the conventional road markers, when a reflector is attached to an inclined side facing a road running direction, or a light emitting body is mounted, a driver of a vehicle traveling along the road visually confirms the reflector or the light emitter and recognizes the lane Lt; / RTI > In this case, a vehicle entering from the side of the road is disadvantageous in that it can not recognize a reflector or a light emitter of the road sign.

Also, in the case of a road marker with a reflector attached thereto, if the reflector is impregnated with a foreign substance, the function of the reflector is lost. In the case of the light emitting body, the light emitting body may not emit light due to its own failure.

In addition to these problems, the road markers should be installed on the road surface with a perforator to drill a hole with a depth of about 5 cm to insert the pillar. Therefore, there is a disadvantage that the amount of work required for the entire work before the installation of the road sign, the working time is lengthened, and the road is broken.

Disclosure of the Invention The present invention has been made to solve the problems of the prior art as described above, and it is an object of the present invention to provide a road marking bottle coated integrally so that the reflector and the phosphorescent body are not discolored or detached even under an external influence or an external impact have.

In addition, the present invention provides a road sign designed for a vehicle driver and a pedestrian who are traveling on a long distance, night, or rainy day, as well as a vehicle driver and a pedestrian located in different directions, It has its purpose.

Further, according to the present invention, when the vehicle is brought into contact with the vehicle, the height of the vehicle is low, so that a large impact is not generated. However, the upper surface of the vehicle has a large friction with the vehicle wheel. The purpose is to provide a road sign constructed.

According to an aspect of the present invention, there is provided a road sign including a body having an inclined surface at an upper surface and a narrower area than a lower surface of the body, a phosphor disposed at an upper surface of the body, a reflector positioned at the inclined surface, And a transparent portion coated on the upper surface and the sloped surfaces, wherein the transparent portion covers the reflector is a convex lens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a road sign according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1A is a perspective view of a road sign according to an embodiment of the present invention, FIG. 1B is an exploded perspective view of the road sign shown in FIG. 1A, and FIG. 1C is a bottom view of a road mark shown in FIG.

1A to 1C, a road marker 100 includes a main body 110 having a quadrangular pyramid shape having a top surface and a bottom surface flat, a phosphorescent body 140 attached to the top surface of the main body 110, And a transparent transparent part 160 which covers the main body 110 to which the reflector 150 and the phosphorescent body 140 are attached, A portion of the transparent portion 160 covering the reflector 150 is formed of a convex lens 165.

In the following, we will explain the road signs in this way.

1A to 1C, the main body 110 has a quadrangular pyramid structure. The upper surface of the main body 110 is formed to have a smaller area than the lower surface of the main body 110, and four inclined surfaces are formed on four sides of the main body 110 .

Here, a concave portion is formed on the lower surface of the main body 110 in a predetermined pattern (hereinafter referred to as a concave pattern 135). The reason why the concave pattern 135 is formed on the lower surface of the main body 110 is that the adhesive applied on the lower surface of the main body 110 and the adhesive applied on the road are pushed by the road surface into the concave portion, It is possible to precisely adhere and fix it to the point where it is intended to be attached. If the undersurface is not formed and is flat, the road marker 100 is pushed by the liquid or gel adhesive and can not be accurately attached to the point of attachment. In addition, since the adhesive is adhered after being introduced into the recess, the area of contact with the adhesive greatly increases, and the road marker 100 can be fixed firmly on the road.

On the upper surface of the main body 110, a first groove 113 in which the phosphorescent body 140 can be positioned is formed. The phosphorescent member 140 is also fixed to the first groove 122 by an adhesive.

In addition, a second groove 122 is formed on the two inclined surfaces corresponding to each other in the main body 110, in which the reflector 150 is seated in the longitudinal direction of the inclined surface. The reflector 150 is also fixed to the second groove 122 by an adhesive.

After the reflector 150 and the phosphors 140 are attached and fixed to the main body 110, the transparent portion 160 covering the upper surface of the main body 110, that is, the upper and lower surfaces of the main body 110, It goes through.

The transparent part 160 is made of a transparent engineering plastic material and is coated on the body in a state of being mounted on the body under high temperature and high pressure conditions and then transmitted through the transparent part 160 to the reflector 150 and the phosphorescent body 140 Incident and reflected.

Engineering plastics are high-strength plastics which are stronger than steel, abundant in malleability than aluminum, and resistant to chemicals more than gold, which are used as industrial or structural materials. Performance and characteristics depend on its chemical structure. It is mainly composed of polyamide, polyacetyl, polycarbonate, PBT (polyester resin) and modified PPO (polyphenylene oxide) Is, in contrast, a few hundred thousand to several million polymeric materials.

Such an engineering plastic is excellent in strength and durability and protects the main body 110, the reflector 150, and the phosphorescent body 140 from impact and ultraviolet rays while being coated on the upper surface and the inclined surfaces of the main body 110.

On the other hand, the transparent part 160 made of engineering plastic has a convex lens 165 formed on the side surface of the transparent part 160 corresponding to the reflector 150.

As the convex lens 165 is formed at the portion corresponding to the reflector 150, the brightness of the retroreflective reflection is increased, so that the pedestrian and the driver can clearly see the road marker even at a long distance, at night or in a rainy day.

On the other hand, the transparent part 160 made of engineering plastic has a quadrangular pyramid-like protrusion 161 aligned on its upper surface, that is, the upper surface of the main body 110.

Since the pyramid-shaped protrusions 161 are formed in this way, the rainwater drains smoothly through the valleys between the protrusions 161 during rain, and the protrusions 161 are prevented from sliding And it is easy to recognize that the driver has entered the lane where the road sign 100 is installed. Such a slip prevention and driver's perception function can further enhance the effect by adding a separate projection 163 to the upper end of each of the projections 161. [

In addition, the transparent protrusion in the form of a pyramid is refracted while the light generated from the phosphorescent body 140 passes through the interface of the protrusion 161 and is emitted. Therefore, the light of the phosphorescent body 140 refracted anywhere and the light reflected by the reflector 150 can be recognized around the road sign 100.

Therefore, even if the road marker 100 is mounted on the road along the lane, the road marker 100 can be easily recognized not only in the vehicle running in the lane but also around the road.

The reflector 150 and the phosphorescent body 140 are attached and fixed to the main body 110 with an adhesive agent but the reflector 150 is seated in the second groove 122 and the phosphorescent body 140 is disposed in the first The transparent portion 160 covers the main body 110 and can coat the transparent portion 160 integrally with the main body 110 under high temperature and high pressure conditions. This is because the transparent part 160 is formed integrally with the main body 110 so that the reflector 150 and the phosphorescent body 140 are placed in the second groove 122 and the first groove 113, The reflector 150 and the phosphorescent material 140 do not separate from each other.

Before the coating process, the transparent portion 160 is formed with a convex lens 165 corresponding to the reflector 150, and when the transparent portion 160 covers the main body 110, the reflector 150 and the transparent portion 160 Convex lenses 165 are correspondingly positioned to form a high-temperature and high-pressure condition, and the transparent portion 160 is coated integrally with the main body 110. [

In FIG. 1, the main body 110 is formed in a shape of a quadrangular pyramid with a yellow horn, a luminous body 140 with a quadrangular shape, and a protruding portion 161 with a quadrangular pyramid shape. However, as illustrated in FIGS. 2 and 3, The marker can be formed in the shape of a triangular pyramid, and the color of the body 110 can be manufactured in various colors such as white, red, blue, and black. The luminous body 140 disposed on the upper surface of the main body 110 may be formed in various shapes such as a square, a triangle and an arrow and the protrusion 161 may be formed in various shapes such as a triangular pyramid as well as a quadrangular pyramid .
