Description

Road stud for intersection

The present invention relates to an intersection marker bottle, and more particularly, an intersection marker bottle installed at the center of an intersection to recognize the position of the intersection and at the same time to recognize an entrance situation of another vehicle entering from the left and right directions of the intersection. It is about.

In general, road markers are installed on the floor of the road to clearly distinguish lanes, center lines, or roadsides of the road, and reflectors are attached to the driver's vehicle so that they can be identified at night. It is.

In particular, the driver makes it easier for the driver to identify the road lane at night or in bad weather. In addition to the road center line, it is also used for displaying boundary lines, road obstacles, safety zones, road lines, guide lines, and the like.

The road sign bottle is composed of a body formed in a rectangular shape as a whole, and a reflecting plate attached to the front and rear of the body with a predetermined color. Such a road sign bottle is reflected only forward and backward (forward or backward direction) on the road surface. Therefore, only the vehicles traveling forward and backward on the road can identify the reflected light of the road marker, but the vehicle entering the side of the road at the intersection of '+' or 'T' can identify the reflected light of the road marker. There was no problem.

To this end, a reflector made of a convex mirror is installed at the intersection, but due to its large volume, the installation space and cost increase, and management and maintenance are difficult.

Republic of Korea Utility Model Registration No. 20-0350736 (2004.05.06), the road marker bottle 100 is formed in a circular shape so that it can be reflected in all directions, so even in severe roads such as 'T' intersections or mountainous areas There has been disclosed a total reflection road marker bottle having a wide angle of reflection for easy identification even in a distant lane (see FIG. 1).

However, such a conventional total reflection road marker bottle is a circular reflection as a whole, the reflection range can be increased, but there is a problem that the reflection efficiency is lowered by being dispersed without focusing the light in a specific direction to reflect.

In addition, since light is dispersed, reflectance reflected to the front surface is relatively low, and thus, it is difficult to recognize the location of the intersection from the vehicle entering the intersection.

In addition, the reflected light is distributed in the vertical direction as well as the left and right directions, there was also a problem that can not use the light efficiently.

Republic of Korea Utility Model Registration No. 20-0350736 (2004.05.06)

The present invention is to overcome the above-mentioned problems of the prior art, is installed at the center of the intersection of the light emitted in the front and rear direction by reflecting the light in a specific direction to reflect by refracting in the left and right direction to reflect the high reflectance The purpose is to provide a crossover marker bottle with excellent sex.

Another object of the present invention is to provide an intersection marker bottle in which the light irradiated in the front-rear direction is reflected by the left and right sides and at the same time, it is also reflected in the front to easily recognize the location of the intersection.

In addition, another object of the present invention is to provide an intersection marker bottle that reflects light irradiated in the front and rear directions to the left and right sides and simultaneously concentrates the light in the vertical direction to improve the light transmission efficiency.

In order to achieve the above object, the present invention, in the intersection marker bottle having a main body installed in the center of the intersection, the side reflector plane reflector is formed on at least one side of the main body to orthogonal to the vertical plane of the bisector of the intersection intersection angle An intersection marker is provided.

In addition, the main body is mounted thereon and fixed, but may further comprise a support plate fixed to the road surface of the intersection by forming a full-use flat reflector to be orthogonal to the vertical plane of the intersection intersection angle on the side.

In addition, a corner reflector may be further formed by chamfering the side edges of the main body to be perpendicular to the vertical plane of the intersection intersection angle.

The side reflector planar reflector has a flat front face, a plurality of semicircular grooves having a concave rear end of the flat cross section, and a rear face formed with a plurality of triangular grooves having a side cross section uneven at an angle of 90 degrees.

As shown, intersections such as back streets of residential areas, especially when parking in a narrow dense area, are not only difficult to identify the location of the intersection because the vehicles are closely parked on the left and right near the intersection, It will not be identified.

The intersection marker bottle of the present invention is an intersection marker bottle having a main body 10 installed at the center of an intersection, wherein at least one side surface of the main body 10 is perpendicular to the vertical plane of the bisector of the intersection intersection. (11) is formed.

In the present invention, the reflector is rotated at an angle of 45 degrees with respect to the intersection as shown in FIG. 2 in order to refract and reflect only the lights of the vehicle to be crossed, that is, the vehicle entering from the side of the intersection, without reflecting the headlights of the own vehicle.

For example, if there is a vehicle “A”, “I”, “D” approaching an intersection of type “+”, the headlights illuminating at “A” are “I” or “D” along the path of ABC or ABD. Each of the vehicle is transmitted to the vehicle, and since the side reflector flat reflector 11 is disposed at an angle of 45 degrees, the light of the own vehicle is not reflected to the vehicle. Conversely, headlights from "I" and "C" vehicles are delivered to the "A" vehicle along the path of the C-B-A or D-B-A.

On the other hand, even at the intersection of the "T" type by installing the intersection marker bottle of the present invention in the same manner as described above, the headlights of all vehicles that cross at right angles can be recognized by the other vehicle, the vehicle suddenly protrudes from the side of the intersection Can prevent accidents.

In addition, since not all cross-driving vehicles approach in a direction perpendicular to orthogonal to my vehicle exactly, there may be some error in the installation angle even when the intersection marker is installed, so that the reflector allows a certain angle change. The installation structure is also required, and the change of such a structure can be variously modified without departing from the gist of the present invention.

On the other hand, in order to easily recognize the reflected light, the intensity of the headlights of the reflected party should be stronger than the surrounding brightness, so it is necessary to have a structure of a reflector that concentrates in a desired direction without scattering light as much as possible.

3A to 3C illustrate a structure for allowing light to be concentrated and transmitted without being dispersed.

3A to 3C are views for explaining the operation of the reflector of FIG. 2.

As shown, the side reflecting flat reflector 11 has a flat front face 11a, a plurality of semicircular grooves with concave rear surfaces of the flat cross section, and a plurality of triangular grooves with side cross-sections uneven at a 90 degree angle. It has a rear surface 12 formed. In this embodiment, a reflective material 12a is applied to the rear surface 12. The reflective material may be plated with a metal such as silver.

As shown in FIG. 3A, the reflector is made of glass or transparent plastic, and the front face 11a is flat and the rear face 12 has a 90-degree-long cross-sectional line extending horizontally. The rear surface 12 may be configured to apply a reflective material 12a as in the present embodiment or to reflect light entering the front surface by using total reflection. The 90 degree horizontal grooves are inserted so that the incoming light can be concentrated and reflected without being scattered. This will be described in detail below with reference to FIGS. 3B and 3C.

3B is a cross-sectional view taken along the line A-B in FIG. 3A. When light enters in the a direction, it is reflected in the d direction through b and c, and when light enters in the e direction, it is reflected in the h direction through f and g. Eventually, even if the angle of up and down changes slightly, the reflected light eventually goes to the same angle as the incoming path.

On the other hand, Fig. 3c shows a flat reflector on the back, where light coming from i goes through j through k, and light from l goes through m through n. As a result, only when light enters the reflector at right angles, the light is reflected in the input direction. In other cases, the reflected light goes in a direction different from the direction in which the light enters.

Here, the reflecting plate 11 of FIG. 3A has only 90 degrees of horizontal grooves, so when the incident angle changes up and down, the reflecting plate 11 goes in the incident light direction regardless of the change of the up and down angle, but when the incident angle changes in the left and right directions of the reflecting plate 11, Similarly, the angle of incidence and the angle of reflection are the same, but in opposite directions.

The reflection of light is a phenomenon in which the light bounces off the boundary of the medium as if the light in the wall bounced off the wall. The reflection of light follows the law of reflection. That is, the light rays incident on the interface and the light reflected from the interface are always symmetric with respect to the imaginary normal perpendicular to the boundary line. Therefore, the incident angle formed by the incident light and the normal and the reflected angle formed by the reflected light and the normal are always the same. This law of reflection can be explained by Fermat's minimum time principle and Huygens' principle.

Therefore, when the reflecting plate 11 of FIG. 3a is formed at the intersection cover bottle body 11 as shown in FIG. 2 and installed at an angle of 45 degrees, the incident light is refracted by 90 degrees in the left and right directions and is directed to the oncoming vehicle in the perpendicular direction. You will see the effect of preventing and focusing light scatter.

The collision risk of intersecting vehicles is greatest when two vehicles approach the same speed at the same distance from the center of the intersection. In this case, as shown in FIG. 3A, a reflector having 90 degrees of horizontal grooves at an angle of 45 degrees to the road direction is shown. When placed and used, the brightest concentrated reflected light can be sent and received from the relative vehicle, which is very effective for vehicle identification.

The 90 degree uneven structure of the rear surface 12 of the reflecting plate 11 of this invention can utilize a retroreflective property. Retroreflective is a feature of light that defines the return of light to a place where it is emitted (called a light source) regardless of the angle at which light or other radiation hits it (this is different from mirror reflection, which is precisely because the mirror It only happens when it is vertical). This phenomenon can be obtained in two ways. One is a set of vertical mirrors (called a cube-corner), and the other is a transparent sphere with a reactive index. It is this property of light that makes it possible to secure high visibility and safe locations in places with heavy traffic, in construction sites, and in places where clarity is needed under any one adverse condition.

4A to 4C are views illustrating the reflector of FIG. 2 in detail in each direction. FIG. 4A is a plan view of the reflector, FIG. 4B is a front view, and FIG. 4C is a side view. As shown, the side reflecting flat reflector 11 has a flat front face 11a, a plurality of semicircular grooves with concave rear surfaces of the flat cross section, and a plurality of triangular grooves with side cross-sections uneven at a 90 degree angle. It has a rear surface 12 formed.

When the reflector plate 11, which is completely horizontal, as shown in FIG. 3A, is attached to the intersection cover bottle body 10 and installed at an angle of 45 degrees as shown in FIG. 2, the installation angle is not accurate or the angle of the approaching vehicle is not completely right angle. In some cases, some reflected light may be out of the driver's field of view.

In order to prevent this, as shown in Figure 4a to arrange the concave-convex groove of 90 degrees on the rear surface 12 of the reflector 11, when viewed in the plane above, as shown in the figure to follow the surface of a number of semi-circular winter, up and down It is a flat mirror, and the effect of the structure in which a plurality of convex mirrors are arranged to the left and right is achieved, and even when the angle of installation of the intersection marker bottle is slightly skewed or the angle of the approaching vehicle is not a perfect right angle, The driver may concentrate on the driver of the vehicle (see FIG. 5).

6A to 6C are perspective views illustrating other embodiments of the reflector of the present invention.

Instead of a horizontal stripe reflector as shown in FIG. 4A, a convex mirror 16a protruding in a semicircular shape on the front side as shown in FIG. 6A, and a cylindrical mirror 16b protruding a semi-cylindrical surface on the front side as shown in FIG. 6B. Alternatively, as shown in FIG. 6C, each reflecting plate 11 having one or more combinations of protruding elliptical mirrors 16c having a long vertical width and a narrow horizontal width may be used. In this case, since the reflected light is also dispersed up and down, the intensity of the reflected light reaching the driver's eye is slightly lower than that of the horizontal striped reflector 11, so that the lights of the crossing vehicles approaching the same distance are reflected more brightly. Although may be reduced, the reflection efficiency compared to the prior art is generally increased, the desired reflection efficiency target in the present invention can be achieved to some extent.

7 is a side view showing a second embodiment of the intersection marker bottle according to the present invention, Figure 8 is a perspective view of FIG.

As shown in FIG. 7, the side reflecting flat reflector 11 is formed upward at an angle of about 2.9 degrees from the vertical surface of the side surface. In the case of installing the reflector, it is preferable to face upward rather than to install it vertically. The reason is that when the vehicle approaches the intersection to some extent, the angle of incident light is slightly lowered, and it is efficient to arrange the reflector vertically in accordance with the incident direction.

Computing the most efficient angle above, assuming that the mean height of the headlights of the vehicle is about 1 m and the light is best seen when the vehicle is 10 m from the center of the intersection, the angle a is tan ^-1 (1/20) The calculation result is about 2.9 degrees. Therefore, as shown in the figure, it is preferable to form upwards at an angle of about 2.9 degrees from the vertical plane, but the value of such an angle may be adjusted to the upper and lower limits within a certain error range.

In addition, as shown in FIG. 8, at least one side surface of the main body 10 is formed with a side reflecting flat reflector 11 so as to orthogonal to the vertical plane of the bisector of the intersection intersection angle, and seating the main body 10 thereon. It is fixed by, but further comprises a support plate 13 is fixed to the road surface of the intersection by forming a full-use flat reflector plate 13a to be orthogonal to the vertical plane of the intersection intersection angle on the side.

In this case, the total reflection planar reflector 13a is disposed at a 45 degree angle with respect to the side reflector planar reflector 11.

Therefore, it is possible to easily recognize the position of the intersection by refracting and reflecting the light irradiated in the front-rear direction to the left and right and at the same time.

9 is a perspective view showing a third embodiment of the intersection marker bottle according to the present invention.

As shown, the side reflector planar reflector 11 is formed on at least one side of the body 10 to orthogonal to the vertical plane of the bisector of the intersection intersection angle, and the intersection intersection angle by chamfering the side edges of the body 10. An edge reflecting plate 14 formed to be orthogonal to the vertical plane of is further formed. In addition, it further includes a support plate 13 which seats and fixes the main body 10 thereon and the lower part is fixed to the road surface of the intersection.

In this case, the edge reflector 14 is disposed at a 45 degree angle with respect to the side reflecting flat reflector 11. The surface of the side reflecting plane reflecting plate 11 is planar, and the edge reflecting plate 14 may be planar or some smooth surface.

When approaching the intersection at night in a very dark place, the intersection marker does not reflect my headlights, so it is difficult to identify the intersection. In addition, there is a case where it is difficult to quickly distinguish whether the vehicle is the right vehicle or the left vehicle even when the light from the crossover planned vehicle is reflected. Therefore, in order to facilitate nighttime identification, as shown in FIG. 9 at the corner of the intersection marker bottle chamfered to install the corner reflector 14 in the forward facing corner, the vehicle in progress can see the headlight reflected light of the vehicle The position of the intersection can be identified, and since the reflected light of the entry vehicles on the left and right sides is seen from the left and right side reflecting flat reflector 11 on the left and right, it is possible to distinguish the left and right approach vehicles.

In addition, since the intersection marker bottle of the present invention is installed at the center of the intersection of the back road, pedestrians and bicycles can pass, and for safety during pedestrian and bicycle traffic, bicycle wheels are pedestrians at the corners of the top of the marker bottle body 10. In addition, care should be taken to provide grooves or protrusions in the upper corners to prevent the bicycle wheels from slipping. To this end, a plurality of concave anti-slip grooves 15 are formed at intervals of a predetermined width at corners where the side and upper surfaces of the main body 10 are in contact with each other.

10a to 10e is a view showing a state in which the intersection marker of the present invention is applied to the intersection by applying in various forms.

When the present invention is applied, it can be utilized not in orthogonal intersections but in T-shaped or three-way. As shown in FIG. 10a, the rectangular cover bottle 10 of the first embodiment of the present invention may be used as it is, and may be manufactured in a triangular form in which reflective plates 11 are disposed on two surfaces as shown in FIG. have.

Where the narrow road and the wide road meet may be installed so that the reflector plate 11 is disposed on one surface of the intersection marker bottle 10 as shown in FIG. If the road is orthogonal, it is recommended that the angle of the reflector be 45 degrees to the road, but if the road is not at right angles, the angle should be changed.

If the road crossing angle is not a right angle as shown in FIG. 10d, the reflector 11 should be disposed to be perpendicular to the bisector of the road crossing angle. Even in the case of a three-way intersection as shown in FIG. 10E, the intersection marker bottle 10 may be deformed into a triangle so that the reflector plate 11 is installed at right angles to the bisector of the road intersection.

As a result of examining various applications, the intersection marker bottle 10 of the present invention can be defined as having a reflector plate 11 perpendicular to the bisector of the road intersection angle, and at an intersection perpendicular to this definition, the installation angle of the reflector plate is 45 degrees with the road is consistent with that illustrated in FIG. 1, and in other cases, as shown in FIGS. 10D and 10E, the reflected light of the crossover vehicle light may be easily detected by another driver.
