Description

ROAD MARKER USING OPTICAL FIBER}

The present invention relates to a road sign that emits light.

'Road sign' is a road attachment under Article 3 of the Road Act and Article 30 of the Regulations on Structural / Facility Standards of Roads, followed by severe deterioration of visibility at night or in rainy weather. It means the line of sight induction facility to complement traffic alignment and to induce the driver's gaze clearly and to promote traffic safety and smooth communication.

At night or in the rain, it is more difficult for the driver to recognize the lane, which increases the probability of a car accident.

Therefore, road markers are appropriately installed in areas that need to supplement the functions of road markings such as road center lines, lane boundaries, dedicated lanes, roadblocks, and safety zones and to raise the driver's awareness of linear induction or changes in the road environment.

Roadway zone line, rapid curve, tunnel, lane reduction / separation / consolidation section, passage change, traffic island, interchange gore area, two-way road including left turn lane, multi-lane road that is not physically separated, road width This narrow bridge is a typical installation section.

Korean Patent Application No. 10-2001-0060710 discloses the structure of a road sign bottle.

On the other hand, the general road sign bottle is divided into a reflective type and a light emitting type according to the driving method, and the light emitting type is subdivided into a flashing type, a lighting type and a switching type.

The reflective road sign is a structure that reflects the headlight of the vehicle without the self-luminous function.

Therefore, it is relatively inexpensive and easy to install, but in order to implement a reflective surface at a predetermined angle, it must be installed to protrude a certain amount from the road surface, thereby degrading road stability and running performance and shortening the life due to wear of the reflective surface.

On the other hand, the light-emitting road sign has a light emitting function such as LED (light-emitting diode) built-in has a self-light emitting function.

Therefore, since it may be buried in the ground so as not to protrude from the road surface, there is an advantage in stability and runability, but there is a problem in that the structure is complicated and the failure rate is high because a power supply device for light emission is required.

Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

The present invention relates to a road sign bottle installed on a road surface so that a driver of a vehicle traveling on a road can quickly recognize a lane or the like by emitting light.

By the way, the present invention has an object of making the road sign bottle excellent in inducing the driver's gaze, low production cost, easy installation, long life and energy efficiency.

To this end, in the present invention, by providing the optical fiber in the road sign bottle, the optical fiber is emitted from the object such as the headlights of the vehicle or the street lamps of the surroundings, and then diverted again through the optical fiber.

That is, a structure that emits light by receiving electric energy has a problem of high failure rate, high manufacturing cost, difficult installation, and short life, and low energy efficiency.

Therefore, it is provided with an optical fiber for re-emitting light by receiving the surrounding light without using a separate electric energy, by the optical fiber to have the effect that the road sign to emit light.

However, if the light is to be received in only one direction, and the light is emitted only in one direction, the effect of inducing the eyes does not meet expectations, so install a plurality of optical fibers and emit light through each optical fiber. The direction to be made is a plurality of directions.

To explain the effect of this structure as a specific example, if the distance generated by the driver's vehicle does not reach the distance, but there is a vehicle driving in the opposite lane, the road is driven by the light of the vehicle driving in the far lane. Since the marker can emit light, it will be possible to identify road markers over long distances.

The technical idea of the present invention as described above can be applied to both a buried road sign bottle and a protruding road sign bottle.

The road sign bottle of the present invention implemented in a buried type, has a cover bottle body 100 exposed on the road surface.

In addition, the upper surface of the installation space 101 is buried in the road surface, and coupled to the lower side of the cover bottle body 100 has a space forming body 200 is to be blocked by the cover bottle body (100).

In addition, it is located in the installation space 101 of the space forming body 200, each having a plurality of optical fiber installation body 400 which is installed to face in a different direction.

Moreover, it has a some optical fiber 600.

However, a large difference occurs in the effect of achieving the object of the present invention depending on the installation form of the optical fiber.

The installation form of the optical fiber for achieving the object of the present invention can be largely divided into three forms.

Specifically, as shown in FIG. 3A, one end is fixed to one optical fiber installation body 400 and the other end is fixed to the other optical fiber installation body 400.

Another installation form of the optical fiber 600, so that the optical fiber is installed for each optical fiber installation body 400, as shown in B of FIG. 3, the middle portion of the optical fiber is bent and both ends are in the same optical fiber installation body 400 It is fixed but is fixed in the same direction.

In addition, it can be implemented in the form as shown in C of Fig. 3 is applied to both the installation form.

The road sign bottle of the present invention embodied in a protruding shape has a road surface exposure portion 10 exposed on the road surface as shown in FIG. 5.

In addition, it has a road surface fixing portion 20 which is located below the road surface exposure portion 10 and fixed to the road surface.

In addition, both ends have an optical fiber 60 fixed to the road surface exposed portion 10.

Even in the structure of the exposed road sign bottle, the installation form of the optical fiber 60 can be largely divided into three types.

Specifically, as shown in FIG. 5B, the ends of the optical fiber are fixed to face in different directions.

In another installation form of the optical fiber 60, as shown in Figure 6A, both ends are fixed to the road surface exposed portion 10, but the middle portion is bent and both ends are fixed to face in the same direction.

In this structure, some or all of the plurality of optical fibers 60 should be directed in different directions.

As another form, it may be implemented in the form as shown in B of FIG.

In the exposure type road sign bottle, it is preferable that the portion where the optical fiber 60 is installed forms the inclined surface 11 because light enters the optical fiber 60 and light diverges smoothly.

In addition, there is an effect that can reduce the impact applied when the wheel of the vehicle traveling on the exposed portion.

The optical fibers 60 and 600, which are the components of the present invention, are preferably fixed while several or tens are gathered to form an optical fiber bundle, in consideration of ease of manufacture, manufacturing cost, light emission, and the like.

In the present invention, a separate fixing means 300 for firmly coupling the above-described space forming body 200 may be further provided.

The fixing means 300, the upper portion is caught in the through hole 210 formed in the lower surface of the installation space 101 of the space forming body 200, the lower portion is passed through the through hole 210 pin is fixed to the road surface or It may be in the form of a conventional bolt, piece, anchor bolt.

The fixing means 300 as described above may be provided in plural. In this case, a plurality of the through holes 210 may be formed to correspond to the number of the fixing means 300.

The cover bottle body 100, which is a component of the present invention, may be in the form of a disc, or may be in the form of a square plate.

The space-forming body 200 which is a component of the present invention may have a form in which a part of the lower part is buried under the road surface of the road or the whole is buried.

The coupling method of the cover bottle body 100 and the space forming body 200 may be implemented to be a spiral coupling method.

The optical fiber, which is a component of the present invention, may be a plastic optical fiber, which is a thin clad made of a core made of high purity acrylic resin (PMMA: poly methylmethacrylate) and a special fluorinated poly methylmethacrylate (F-PMMA). Optical fibers composed of clad layers can be used.

Since the optical fiber has a large light receiving angle, a large amount of incident light is suitable for receiving a vehicle light or various lights around a road.

In addition, it is excellent in bending resistance and strong against bending, and transmits only light, so there is no heat generated from the optical fiber itself, and there is no electrical risk such as leakage, discharge, etc., so it can be installed in a narrow and dangerous place.

In addition, since the optical fiber does not need a lamp or a power supply, there is little risk of damage, and since it can be used semi-permanently without A / S because it can maintain a constant illuminance, it is suitable as a light emitting member of a road sign bottle.

If the cover bottle body 100, which is a component of the present invention, is formed of a copper alloy as used in a conventional road cover bottle, the light of the vehicle does not pass through the cover bottle body 100, it is difficult to emit light through the optical fiber.

Therefore, in the road sign bottle using the optical fiber of the present invention, it is preferable that a certain area of the cover bottle body 100 is formed of a transparent epoxy resin and the remaining area is formed of a reflector so that a light movement path can be secured smoothly.

At least the point toward the end of the optical fiber of the cover bottle body 100 needs to be made of a transparent material, it is possible to use an epoxy resin as a transparent material. (The transparent epoxy resin for optical fiber and light diffusion is minute vibration, air pressure And it is not affected by humidity, which does not significantly shorten the life span of road signs.)

In addition, parts (part or all) other than the part implemented with a transparent material (epoxy resin) are made to be a reflector.

Even in such a configuration, the optical fiber installation body 400 should be installed in an inclined shape toward the center of the cover bottle body 100 so that the optical fiber receives and emits light smoothly.

The cover bottle body 100, which is a component of the present invention, has a width wider than an open upper surface of the space-forming body 200 to cover the upper surface of the space-forming body 200 and protrude downward in the remaining area. Means 350 may be formed.

By fixing the auxiliary fixing means 350 on the road surface it is possible to further improve the fixing force.

The auxiliary fixing means 350 as described above, the cover bottle body 100 covers the upper surface of the space forming body 200, the side formed of a transparent epoxy resin of the cover bottle body 100 and the side formed of a reflector desired position It can play a role of being fixed to.

The auxiliary fixing means 350 may be implemented in the form of a triangular pointed end.

The optical fiber installation body 400, which is a component of the present invention, is implemented in a unitary form with the cover bottle body 100 to facilitate the assembly work, even if the repair is required, it is possible to quickly repair, and to facilitate the repair work. .

In the present invention, when the road surface is made of wood, tiles, marble and the like, as shown in FIG. 7, the space-forming body 200 is fixed (by buried form) by a mounting nut spirally coupled to the outside of the space-forming body 200. May be fixed).

In other words, between the cover bottle body 100 and the installation nut is placed wood (1) or tile or marble is tightened by the installation nut 310 to be fixed.

Of course, in the case of an exposed road sign bottle, the installation nut is fastened to the outside of the road surface fixing portion 20 so that the road surface fixing portion 20 can be fixed (fixed in a buried form).

The road sign bottle using the optical fiber of the present invention can make the driver easily recognize the lane because the optical fiber receives and emits the light of the vehicle or the surroundings even when the vision is unclear in bad weather or at night, thereby allowing the driver to quickly and accurately in the road situation Allow to react.

In addition, the road sign bottle using the optical fiber of the present invention, even if the vehicle or the surrounding light is emitted from any direction of the road sign bottle has an effect that makes the road sign bottle more clearly recognized by the divergence of light in various directions.

In the present invention, the space forming body 200 is formed with a plurality of protrusions 230 protruding along the outer circumferential surface, it can be fixed firmly when fixed under the road surface.

Reference numeral 110 is a fastening portion of the cover bottle body 100 and the space forming body 200.
