The present invention relates to a road boundary stone, to form a cut surface in the corner portion of both ends of the most vulnerable portion of the road boundary stone to prevent breakage and to arrange the reflecting means on the cut surface so that the vehicle driver can identify it at night It relates to a road boundary stone that can protect the vehicle driver and sidewalks.

The road boundary stone is installed on the boundary between the roadway and the sidewalk to distinguish the roadway and the sidewalk and at the same time, it is formed as a step to act as a barrier to prevent the vehicle from entering the sidewalk.

1 is a perspective view of a conventional boundary stone, and the conventional road boundary stone is usually made of stone or concrete molding, and as shown in the drawing, the part where the front and the upper surface are exposed to the road is faceted, but the front, the upper and the side are The corners meet each other at right angles, which are so fragile that they are easily broken during transportation or disembarkation of the boundary stone, or they are easily broken by external impacts such as bumping or stopping at installation or stopping. In addition, if it is damaged in this way, it is not only coarse in appearance, but also two adjacent boundary stones are installed by connecting the joints with mortar, etc. If the corner is broken, the mortar is dropped from here and the entire boundary stone is applied when a secondary shock such as a vehicle is applied. The problem is that structural problems are bad, such as aggravating the damaged state.

In addition, when driving at night on a road without a street light or a low light, traffic accidents such as crashing into a road boundary stone and entering a sidewalk occurred frequently due to failure to detect a road boundary stone. To prevent this, reflective objects such as luminous paint and reflective tape were attached to the boundary stone. In addition, the angle of the reflector was adjusted so that the light of the vehicle headlight reflected from the reflector and transmitted to the vehicle driver. As a conventional technique in which the reflector is attached and the angle of the reflector is adjusted, registered utility model No. 20-0235031 (registered on June 08, 2001, prior art 1) 'Luminous road boundary stone' and registered utility model No. 20-0230682 (2001.05) .04 Registration, prior art 2) 'Pedestrian road boundary stone with reflector' and the like.

In the prior art 1, the reflector is installed to protrude in front of the boundary stone, which is easily damaged when the vehicle or motorcycle is in close proximity and takes a lot of manpower and time to repair it. Becomes In addition, in the prior art 1 and the prior art 2 to make a recess (or groove) in which the reflector is recessed in the front of the boundary stone, and installing the reflector here is to seriously damage the body of the boundary stone to make the recess (or groove), the boundary stone itself The structural problem of lowering the strength of the material is generated, and additional steps and a small molding mold are required to make the recessed parts, and the material cost and labor cost are input to raise the manufacturing cost. In addition, the prior art 1 and the prior art 2 has a problem that it is easy to break because the corner is formed to have a sharp or right angle as described above.

The present invention has been made to solve the above problems, the primary object is to form a cut surface in the front end edge of the boundary stone to prevent the portion is damaged by an external impact,

It is a secondary object to arrange the reflecting means on the incision surface so that the light emitted from the vehicle is reflected by the reflecting means and directed toward the driver's front so that the road boundary section can be clearly identified.

Road boundary stone of the present invention for achieving the above object,

It has a rectangular columnar shape, and forms cutting surfaces at both end edges of the front surface adjacent to the road boundary, and arranges reflecting means on the cutting surfaces.

In addition, the incision surface is characterized in that the headlights of the vehicle is directly irradiated and formed on the upper surface of the exposed surface of the boundary stone so that the driver can easily check.

And the angle formed by the side of the incision surface formed at one end so that a large amount of light is irradiated to the incision surface is small and the angle formed by the incision surface formed on the other end is large.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a state diagram in which the boundary stone is arranged on the road boundary with the reflecting means 20 according to a preferred embodiment of the present invention, Figure 3 is a perspective view and a cutaway surface of the boundary stone formed with a cutting surface 10 in the corner according to the present invention There are various forms.

2 and 3, it can be seen that the incision surface 10 is formed at the edge of the exposed surface (ie, the front surface). To install on the roadside of the boundary stone, the sides of the boundary stone are arranged to face each other and the butted part is filled with mortar, etc. to install the construction joints (1) or to use the formwork at the site to make and install concrete casting.

At this time, the edge of the boundary stone is fragile and fragile, but the bottom edge of the boundary stone in contact with the floor and the back edge in contact with the sidewalk block (2) are invisible to the field of view so that even if there is damage such as being broken, it does not affect the aesthetics. And even if it breaks, the damaged part is filled by mortar or sand, so there is no problem in structure, but it is exposed at both end edges of the front of the boundary stone adjacent to the road, so it is aesthetically sloppy in case of breakage. It gradually breaks away from the damaged parts such as mortar, which binds adjacent boundary stones, and weakens the binding force between adjacent boundary stones, causing structural problems such as severe damage of the boundary stones due to shaking of the entire boundary stone by the impact of vehicles. do. Forming the incision surface 10 in the corner to prevent this is stronger to the impact, such as to prevent the damage or structural defects caused by such.

Referring to Figure 3 showing the various forms of the incision surface 10, a triangular-shaped incision surface (10a) formed by obliquely cutting the upper edge where the three sides meet, incision vertically from the upper surface to the lower surface or from the upper surface to the middle The formed rectangular incision surface (10b, c), the upper portion of the corner is inclined inclined and the lower portion is inverted inverted trapezoidal shape formed by cutting the surface (10d) can be a variety of shapes. In addition, the corner where the front and the upper surface of the boundary stone meet is also preferable to cut to a flat surface or to smooth the surface treatment to prevent breakage.

Reflecting means 20 is arranged on the cutting surface 10 to prevent the driver from driving the vehicle at night to identify the boundary stone, thereby preventing traffic accidents. As the reflecting means 20, a reflective paint may be painted on the cut surface 10, a reflective film reflecting light may be attached to the cut surface 10, or a diffuse reflector may be attached to diffuse reflection. .

When forming the incision surface (10) at both end corners of the boundary stone is to be noted that a large amount of light is incident on the reflecting means 20 arranged on the incision surface 10, a large amount of the incident light It is necessary to increase the driver's ability to recognize the boundary stone by reflecting it to the driver's field of view.

In order to increase the discriminating power, the area of the incision surface 10 and the angle between the incision surface 10 and the front / upper surface / side surface should be considered.

The larger the area of the incision surface 10, the greater the amount of incident light is advantageous, but there is a certain limitation because it weakens the strength, safety of the boundary stone.

FIG. 4 is a view for explaining the effect of the angle between the incision surface 10 and the incidence on the incidence and reflection of light, and the incision surface 10 is a triangle. The angle formed by the incision surface 10 with each surface should be adjusted so that a large amount of light is incident on the incision surface 10, and the light reflected and reflected is reversed in the direction of incidence, that is, the field of view of the driver. Before explaining this, in the tetrahedron cut out as shown in FIG. 4A, the length of the corner formed by the upper surface and the front surface is L1, the length of the corner formed by the upper surface and the side is L2, and the length of the corner formed by the front surface and the side is L3. A cut surface in which light is incident and reflected is defined as an A cut surface 10A and a cut surface adjacent thereto is called a B cut surface 10B.

4B is for explaining an appropriate incision angle of the B incision surface 10B. Referring to this, the B incision surface 10B should not interfere with the progress of light incident and reflected on the A incision surface 10A. The B incision surface 10B indicated by the dotted line blocks the path of the incident light and is in a solid line. The marked B incision surface 10 does not block the path of light.

In other words, the larger the angle formed by the B-cutting surface 10B with the side surface (that is, the longer L1 is), the greater the amount of incident light. However, if the incision angle is increased, the volume of the incision is increased, which impairs the strength and safety of the boundary stone. Therefore, it is preferable that the angle | corner which B cut surface 10B leads to a side surface is 45-80 degree | times.

In addition, if the angle formed by the B cut surface 10 formed at one end and the side is large, the vehicle does not interfere with the progress of light incident on the A cut surface 10 formed at the other end when the car moves along the boundary stone. When the car faces the front direction of the boundary stone, such as when rotating on the road to change the traveling direction while driving, a large amount of light is incident and reflected on the B incision surface 10, thereby enhancing the driver's boundary stone identification.

4C is for explaining a proper incision angle of the A incision surface 10 and the upper surface. The angle formed between the A cut surface 10A to which light is irradiated and the top surface is related to the height of the vehicle (that is, the height of incident light).

If the vehicle is high, the angle formed by the A incision surface 10A with the upper surface should be small (i.e., L3 should be short), such as the A incision surface 10A indicated by the solid line, and if the vehicle is low, the A incision surface 10A indicated by the dotted line Larger angles (ie, longer L3) are beneficial.

However, the boundary stone that needs to be identified is the boundary stone that is 20-30 m in front of the vehicle, and more than 50 m away. Thus, the farther the distance between the vehicle and the boundary stone that needs to be identified is, the lower the incident light is (ie, the vehicle and the incision surface). Since the angle formed by the imaginary straight line connecting the ground becomes smaller), it is advantageous that the angle formed with the upper surface is large (that is, L3 is long), such as A cut surface 10A indicated by a dotted line. Therefore, in consideration of the distance of the boundary stone which needs to be identified, the preferred angle that the A cut surface 10A makes with the upper surface is 55 to 85 degrees.

4D and 4E illustrate the proper incision angle that the A incision surface 10A makes with the front or side surface. The angle formed between the front and side surfaces of the A cut surface 10A through which light is irradiated is the horizontal distance between the vehicle and the boundary stone in the horizontal direction (that is, the horizontal angle formed by the virtual straight line connecting the cut surface and the vehicle with the longitudinal direction of the boundary stone). Related.

If the vehicle has a large distance from the boundary stone, the angle formed with the front surface is small (i.e., L2 is short), as shown by the incision plane 10A indicated by the solid line in FIG. 4d, and the incision plane 10A indicated by the dotted line in FIG. 4e. The angle with the sides is advantageously large (i.e. longer L1),

If the separation distance is small, the angle formed with the front surface is large (that is, L2 is long) as shown by the cut line 10A indicated by the dotted line in FIG. 4D (ie, L2 is long). Is smaller (ie, L1 is shorter).

In addition, since the boundary stone that needs to be identified is at a distant distance, it is advantageous that the angle formed by the A cut surface 10A with the front surface is small and the angle formed with the side is large. The preferable angle is 55-85 degrees with the front surface and 5-35 degrees with the side surface.

In conclusion, since the boundary stone that requires much identification is installed more than 20m in front of the vehicle, as shown in FIG. 4F, the angle formed by the A cut surface 10A with each surface is large for the front and the upper surface (that is, L2 and L3 are long and ) The small side (ie, L1 is short) is the side, and the B incision surface 10 may be said to have a large angle with the side (ie, L1 is long).

And the edges respectively formed on both sides by the incision surface 10 is preferably matched with each other. This is because when the boundary stone is installed on the side of the road, the adjacent sides coincide with each other to facilitate the construction of the joint by mortar, and the separation of the mortar, which is later bonded by the construction, is prevented.

FIG. 5 is a view illustrating a state in which light is incident and reflected on reflecting means arranged on the cut surface of the boundary stone as a road in which the boundary stone is installed according to the present invention. As shown in the figure, in the present invention, since the cutting surfaces 10, on which the reflecting means 20 are arranged, are formed at both end corners of the boundary stone and enter the driver's field of view, the light emitted from the headlights of the vehicle is cut. It is naturally reflected from the reflecting means 20 of the surface 10 to face the driver's frontal view. In addition, since the incision angles of the A incision plane and the B incision plane are different from each other, the B incision plane does not prevent the progress of light incident on the A incision plane, so that the identification of the boundary stone is high and the boundary stones of the distant as well as the distance can be identified. In addition, the boundary stone installed in the lane opposite to the direction of travel of the vehicle can be identified to a distance without obstacles for safe driving.

As described above, the present invention forms a cut surface at the corner of the front portion adjacent to the road which is the most vulnerable part of the conventional boundary stone to have a strong resistance to external forces such as impact, thereby preventing breakage, thereby preventing aesthetics from being damaged. In addition, there is an economic effect of reducing the amount of mortar that joins the adjacent boundary stones as much as the space in which the incision surface is formed.

In addition, by arranging the reflecting means on the incision surface, the driver can clearly identify the boundary stone, and the incision surfaces at both ends of the reflecting means are arranged differently from each other so that the incident light is not blocked and the maximum amount of incident light is not blocked. The incident light is reflected and the reflected light naturally faces the driver's front, thus enhancing the driver's ability to recognize the boundary stone.

In addition, there is no need for additional processing for the boundary stone to install the reflecting means in the boundary stone, which reduces the manufacturing cost increase factor of the boundary stone, and forms cutouts at the corners of both ends of the boundary stone. There is an advantage that problems do not occur.

In the above description of the present invention, a road boundary stone having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art, and such modifications and changes are the protection scope of the present invention. Should be interpreted as belonging to.
