Description

Marking Block for Traffic Line

This issue is installed on the roadway to call the driver's attention and reflect the headlights of the vehicle at night to accurately indicate the location of the lane, thus preventing traffic accidents that may occur due to the invasion of the center line or prohibited entry area. The present invention relates to a road sign bottle designed to prevent accidents and promote safe driving.

Generally, the boundary line between the center line, shoulder, or bicycle lane of a driveway, the boundary between the driving lane and the access lane, the boundary between the driving lane and the access lane, the no-access zone, the safety zone on the roadway, the safety zone in front of the school or the crosswalk A marker bottle protruding on the surface of the road is placed on the boundary line of the stop line, such that the driving vehicle is in contact with the driver when the vehicle violates the boundary line.

In addition, the cover bottle as described above is provided with a reflector to reflect back light of the headlights shining from a vehicle running at night so that the driver can easily distinguish the lane from a long distance.

Conventionally, most road marker bottles have a structure in which the indicator sphere protruding on the surface of the road has a trapezoidal tetrahedral structure, and the pillars formed integrally with the bottom of the indicator sphere are fixed to the surface layer of the road. The reflector is equipped with the same.

That is, the road marker bottle conventionally used is considered to be a trapezoidal tetrahedron so that only the visibility of the driver in the longitudinal direction (bidirectional) of the road direction is secured, and has an unstable structure that is vulnerable to compression force, bending force and horizontal resistance force.

Therefore, the conventional road marker bottle is a sign sphere protruding on the surface of the road is angled in the shape of a trapezoidal tetrahedron, so that the structure is easily damaged due to a large horizontal impact upon contact with the driving wheel of the vehicle, as well as the impact noise • There was a problem of creating psychological anxiety for the driver due to vibration.

In addition, since the indicators protruding on the surface of the road are subjected to a large impact, the struts are buried in an unstable structure, so buried and irregular rotation occurs on the soft asphalt pavement due to impact force, compressive force, and bending stress. In the case of durability, the pavement was damaged due to the horizontal impact.

In addition, the conventional road sign bottle is a front and rear surface inclined irrespective of the complex road environment of various types of vehicles, such as small vehicles, large vehicles, special vehicles that the reflector that reflects the headlights of the vehicle at night driving retroreflective Since the incident angle of the reflector is limited, the angle of incidence of the reflector is limited and the reflectance angle of the reflector is inconsistent with the driver in the case of a road where the longitudinal or planar line of the road is curved or in a large vehicle. There was a high risk of accidents.

On the other hand, it is impossible to replace or dismantle only the indicators of the marker bottle. Therefore, when the reflection function of the reflector is deteriorated due to the friction of soil, sand or the like, the cost of removing and reinstalling the entire marker bottle is greatly incurred. In addition, there was a problem that the road quality is damaged by being completely buried in the surface layer of the road during the repaving work according to the maintenance of the road.

Therefore, the subject matter of the present invention was devised to solve various problems appearing in the aforementioned conventional road marking bottles.

Therefore, the purpose of this paper is to increase the durability of the indicators protruding on the surface of the road only by the compressive force, and to ensure the incident angle and the reflection angle of the reflector regardless of small, large, or special vehicles to ensure the visibility of the road marker bottle with good visibility. To provide.

Another object of this paper is to provide a road marker bottle to secure the installation of the shoreline buried in the surface layer of the road to maintain a more stable installation state.

Still another object of the present invention is to provide a road marker bottle, which is capable of replacing or dismantling only the indicator by screwing a marker that protrudes onto the surface of the road and a pillar embedded in the surface layer of the road.

Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings in accordance with a preferred embodiment of the present invention.

As shown in Figs. 1 and 2, the road sign bottle in this disclosure has a head portion 11 formed in a spherical shape or a hemispherical shape, and the spherical surface of the head portion 11 is shown. A display sphere (10) having a reflector (12) for ventilating the driver's vision in the; It is connected to the center of the bottom of the display 10, vertically extending downward, a plurality of anti-rotation groove 21 is formed on the outer peripheral surface vertically, a plurality of pull-out projections 22 protruding outward at a predetermined height 22 It is characterized by a basic feature in the technical configuration that is formed;

This proposal having the above technical configuration is located at the center of the road or at a boundary for controlling the entry and running of the vehicle. As shown in FIG. 3, the head 11 of the indicator 10 is connected to the road. It is installed to protrude above the ground surface, and the support 20 is embedded in the surface layer (s) of the road and serves to inform the driver of the driving vehicle when the lane is separated from the driving vehicle.

In the embodiment of the present invention, the reflector 12 has an upper reflection part 12a formed in a circular shape around the apex of the head 11, its upper reflection part 12a and the head part 11 It consists of a plurality of lower reflection parts (12b) formed intermittently and elongated along the transverse direction between the lower ends of the.

This arrangement of the reflector 12 is not only possible to enter in all directions, but also reflected in all directions in a multi-reflective manner, to ensure the driver's visibility perfectly, regardless of curved roads, small, large, special vehicles Given.

The post 20 is basically formed in a cylindrical shape.

The anti-rotation groove 21 is formed in four places at the center of the front, rear, left and right while forming a triangular cross-section in the pillar-shaped support 20 body.

When the anti-rotation groove 21 is entangled with the surrounding surface material when it is buried in the surface layer of the road, even if a force to rotate the cover bottle in the horizontal direction is applied to sufficiently maintain the horizontal position of the cover bottle in response to this rotation force The giving role is faithful.

The anti-drawing protrusion 22 is formed of three layers, each of which is formed as a set of four protruding from the portion except the rotation preventing groove 21 of the support 20. The pull-out protrusion 22 has a wedge shape and protrudes outward.

When the anti-drawing protrusion 22 is embedded in the surface layer of the road, it is entangled with the surrounding surface material, so even if a force is applied to pull the cover bottle upward, the cover bottle maintains the vertical position of the cover bottle in sufficient response. The Lord plays a role.

In the present disclosure, the indicator 10 and the support 20 may be integrally formed, or may be implemented separately.

The preferred embodiment of the present invention provides a structure that is manufactured detachably and screwed together.

That is, the indicator 10 has a neck 13 which protrudes integrally downward from the center of the bottom of the head portion 11 and the male thread groove 14 is formed at the bottom thereof, and the support 20 has its body. It consists of a technical configuration that the female threaded hole 23 is formed in the upper side of the male screw groove 14 of the indicator sphere 10 is screwed.

According to such a screw-type detachable structure, when the turbidity of the reflector 12 is reduced, only the indicator 10 can be removed and replaced when the function is degraded. When resurfacing the surface layer, the display port 10 can be dismantled so as not to pollute the road environment.

As described above, the road sign bottle of the present disclosure has the following effects.

First, since the marking sphere protruding on the surface of the road is composed of a circular arc shape or a hemispherical shape that receives only a vertical compression force, there is no fear of pavement damage due to bending force and horizontal impact force or dropping of the cover bottle. Secure it.

Second, by providing a pull-out protrusion and a rotation preventing groove in the shore buried in the surface layer of the road to ensure a firm fixing force with the road pavement, there is no effect that the cover bottle is buried in the pavement or fall off.

Third, since it is made of a four-way three-dimensional display sphere to secure the incident angle and reflection angle of all vehicles, the long distance to secure safety, it is advantageous to reduce the risk of accidents and to secure visibility according to changes by vehicle and road conditions.

Fourth, since the upper part of the indicator sphere is a reflector, visibility is ensured even on curved roads and poor snow and rainy nights, which are poor in the longitudinal line and the plane line of the road.

Fifth, since the upper structure of the cover bottle is made of a spherical surface that slides well, soil, sand, or foreign matter is not deposited by snow, rain, etc., and thus the reflective ability is not degraded, thereby providing a condition of safe driving.
