BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover bottle that reflects headlights at night or in rainy weather, and displays road boundaries. In particular, the present invention relates to a cover bottle having high reflectivity and excellent visibility and long life span.

At various boundaries of the road, such as the center line or the outer boundary of both sides of the road, a beacon is installed which can induce a driver's safe driving by reflecting the headlights at night or in rainy weather.

As a retroreflective means for reflecting the headlight light in such a cover bottle, it is usually a thin reflective sheet coated with glass beads, which are reflective materials or fine glass beads, or a multilayer structure having a fine retroreflective structure such as a tube corner at the back. Thin plate reflective sheets have been mainly used.

However, such conventional marker bottles are retroreflected by micro reflectors or reflecting structures, such as glass beads or tube corners included in the reflecting sheet, which inevitably accompany the surface when forming or processing the micro reflectors. The relative magnitude of surface roughness, which causes irregular refraction and scattering, is very large when compared to the size of the micro reflector, which causes a problem of low reflectance because the ratio of light being refracted or scattered is high.

In addition, in the case of the conventional label bottles, the reflective sheet having a multilayer structure for protecting the micro-reflector is poor in durability and the reflectance is abruptly decreased in a short period of time due to ultraviolet rays, moisture, and foreign substances, so the reflection life is very short. In a short period of time, gaze induction function was lost.

In addition, at least one layer of protective layer is required to secure the micro reflector such as glass beads or tube corners while protecting it from damage. There was a problem that was very high.

Nevertheless, the conventional cover bottles are expensive because the expensive reflective sheet is so thin that it is easy to be damaged and its durability is very short, so the replacement cycle is very short. There was a problem that should replace the entire cover bottle fixed to the buried. In addition, since replacement of the cover bottle requires excavation of a part of the roadbed, the replacement construction is very cumbersome, and there is an unreasonable problem of costing more than the construction cost.

Due to these problems, for example, the cover bottle vitreous body of Utility Model Registration No. 283381 or the like is formed using a large glass bead or a reflective egg as a reflecting means, or the entire label bottle is made of a transparent material such as glass to have a predetermined retroreflective structure. The same markers were also created.

However, the conventional road markers as described above, although the durability life slightly longer than the conventional markers using the reflective sheet described in the introduction, there is a problem that the visibility of the reflector is rather low due to the low reflection efficiency of the reflector. In addition, since the surface of the reflector is scratched or partially damaged due to the tire friction of the driving vehicle, the effective reflection life is not long because the reflection efficiency gradually decreases over time. In addition, the manufacturing cost was high and the replacement work was very cumbersome, which was very inefficient.

The present invention is to solve the problems of the prior art as described above, the present invention has a high reflectance efficiency of the reflector is not only excellent visibility, but also to maintain the initial reflectance for a long time to provide a label with a long reflection life.

An object of the present invention is to provide a label bottle having a semi-permanent lifespan by allowing the replacement of a reflector with a limited reflection life.

In addition, an object of the present invention is to provide a label bottle having a simple configuration and low manufacturing cost.

Cover bottle according to the present invention for achieving the above object, the head is installed on the boundary of the road; A plurality of reflecting portions having a fixed plate portion attached to the side of the head, and three reflecting surfaces integrally formed with the fixed plate portion and having approximately 90 degrees of inclination with respect to each other to retroreflect light to the reflecting surface. Reflector made; characterized in that it is included.
In the above configuration, the angle between reflective surfaces is within an angle of less than about 90 degrees to reach the driver's eye by reflecting the headlight light conically according to the distance between the driver and the light source (headlight) than 90 degrees. It can be designed larger or smaller at. That is, as is well known in the art, the angle between the reflective surfaces is slightly different according to each national standard or international standard that defines the reflection luminance according to measurement factors such as incident angle, observation angle, and measurement distance. Can be designed. Accordingly, in the description and claims of the present specification, the angle between reflective surfaces is written in '90 degrees' or 'approximately 90 degrees', which is not limited to 90 degrees even when the size of the angle is described as 90 degrees. It means that the design can be changed within the range of '89 to 91 degrees depending on the conditions.

The reflector is a single molded body of a transparent material such as glass or synthetic resin, and the reflecting part protrudes in the shape of a triangular pyramid having a vertical angle of about 90 degrees between the corners of the back of the fixing plate part and a vertical distance of 3 mm or more from the back of the fixing plate part to the rear end. It may be shaped and configured to form the reflective surface with the respective oblique sides of the triangular pyramid. The surface of the reflector may be UV-coated to protect the surface from being scratched by an external force and to prevent foreign substances such as dust from adhering, and may be detachably attached to the head by a detachable fixing means.

According to the above configuration, the cover bottle according to the present invention is installed at the boundary of various lanes such as the center line of the road, and retroreflects the headlight of the car incident from the front to the reflecting surfaces of the reflector installed on the side of the head. The boundary can be clearly displayed to the driver.

Such a cover bottle has three reflecting surfaces formed on the rear surface thereof, and thus reflects most of the incident light in the incident direction irrespective of the incident angle of the light and the refractive index of the material itself. In addition, as long as the reflector is not damaged or scratched on the surface, the reflectance is not lowered by ultraviolet rays or moisture, and thus the initial high reflectance can be maintained for a long time. In particular, since the reflector is installed on the concave surface formed on the side of the head so that its surface is positioned inwardly lower than the outermost surface of the head to avoid friction with the tire or the like, there is no fear of scratching by the tire or the like. Even if it loses its reflection function, only the reflector can be replaced with a new one to restore the reflection function, so the initial reflection luminance can be maintained semi-permanently unless the head is lost.

Hereinafter, a preferred embodiment of the label bottle according to the present invention.

Example 1

1 shows a perspective view of a road on which a cover bottle according to the first embodiment is installed, and FIGS. 2 and 3 show a perspective view of the cover bottle according to the first embodiment and a side cross-sectional view taken along the line A-A of FIG. 4 shows a perspective view of a reflector according to the first embodiment.

As shown in FIG. 1, the cover bottle 10 is installed at the boundary of the road to inform the driver of various boundaries on the road at night or in the rain, and the cover bottle 10 according to the first embodiment is illustrated in FIGS. 2 and 3. As shown, the anchor 11 embedded in the ground of the road, the head 12 is installed on the top of the anchor 11 protrudes over the road surface, the reflector 13 is attached to the side of the head 12, etc. Consists of.

As shown in FIG. 4, the reflector 13 is a rectangular plate-shaped fixed plate portion 130 fixed to the side of the head 12 and a triangular pyramid protrudes from the rear surface of the fixed plate portion 130 to each other. A single molded body in which a plurality of reflecting portions 131 forming the reflecting surfaces 131a, 131b, and 131c are formed integrally with three sides contacting at approximately 90 degree angles, and formed of a transparent material such as glass or transparent synthetic resin. In some cases, pigments may be mixed to give a specific color of light when needed. The reflector 13 is preferably molded by injection, but may be manufactured through a machining process. In the case of manufacturing by injection method, the surface roughness of the front surface and the reflecting surfaces 131a, 131b, and 131c of the fixed plate part 130 may exceed the predetermined level so that the reflectance may be lowered. Machining process may be performed to smooth the process. The reflective surfaces 131a, 131b, and 131c may reflect light because the light is refracted at the front of the fixed plate part 130 and is mostly incident above the critical angle. However, the reflective surfaces 131a, 131b, and 131c may reflect even when the incident angle is smaller than the critical angle. In order to further increase the reflection film (not shown) may be coated through a vacuum deposition process or the like. The reflecting film may be replaced by reflecting means such as silver foil attached to the rear surface of the reflector or other reflecting means such as a glossy layer formed directly on the wall surface of the settling groove 12b. The size and quantity of the reflective parts 131 may be variously changed within a range in which the vertical distance D from the rear surface of the fixed plate part 130 to the vertex of the reflective part 131 is 3 mm or more. When the vertical distance D is 3 mm or less, the reflectance is not preferable because of the influence of surface roughness.

As shown in FIG. 3, the reflector 13 is formed on the side surface of the head 12 so as not to be rubbed into a tire, and thus may have a function of cushioning function on the recessed surface 12a immersed inward. It adheres by the resin adhesive 14. At this time, the reflecting portions 131 on the rear surface are accommodated in the settling groove 12b formed in the head.

Meanwhile, the head 12 is shaped into a substantially square shape when viewed from above, but may be changed into a circle, a hexagon, an octagon, and other various shapes. In this case, the structure of the reflector may be changed to a suitable shape according to the shape of the head.

An anchor is embedded in the ground to fix the head 12, and is excluded from the configuration in the attachable label bottle.

In the cover bottle 10 according to the first exemplary embodiment of the present invention having such a configuration, the head 12 is installed to protrude above the road surface on the boundary line of the road. The headlight light incident from the front of the reflector 13 is formed by the three reflecting surfaces 131a, 131b, and 131c formed on the rear surface of the reflector 13 according to the incident angle or material material. Irrespective of the refractive index and the like can be reflected with a high luminance in the incident direction, by displaying the boundary line of the road clearly to induce the driver to drive safely.

In the cover bottle 10, most of the incident light of the reflector 13 is hardly affected by the surface (the front surface of the fixing plate 130 and the surface roughness of the reflective surfaces 131a, 131b, and 131c). The reflection brightness is very high, so the visibility is very high, and therefore, the visibility is very excellent and the driver can clearly imprint the boundary of the road, etc., so the driving safety effect is very high. Therefore, as long as there is no damage or scratches on the surface, the reflectance does not decrease due to external factors such as ultraviolet rays or moisture, and does not directly rub against the tire on the stepped concave surface 12a on the front or back of the head 12. It is installed so that there is little risk of scratching or damaging the tire, so that the initial high reflection brightness can be maintained semi-permanently. If the reflection function is lost for reasons such as being damaged, the damaged reflector 13 can be broken and removed and then replaced with a new one to immediately restore the reflection function. Therefore, the life of the reflection within the range of the head 12 or the like is not damaged or lost. It can be maintained permanently.
