[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a structure of a pedestrian road boundary block with a reflector. More specifically, the visibility of a boundary block is improved by ensuring that the reflected light can be visually recognized by a driver of any vehicle at an appropriate distance. The present invention relates to a pedestrian road boundary block with a reflector.

[0002]

[Prior art]

 A concrete block that separates the roadway from the sidewalk and secures the safety of pedestrians and automobiles is generally called a pedestrian road boundary block. As shown in the perspective view of FIG. Are laid side by side alongside the road.

The cross-sectional shape perpendicular to the longitudinal direction is generally a symmetrical trapezoidal shape (in FIG. 6B, a trapezoidal shape that is vertically stacked in two steps), and has a width of about 20 to 40 cm and a height of about 25 to 40 cm. The lengthwise dimension is about 0.5 to 2 m.

A side end surface of the pedestrian road boundary block (reference numeral 15), which corresponds to an end of the laid pedestrian road boundary block 10, is formed with an inclined surface 5 to avoid damage caused by riding on an automobile tire. In order to increase the visibility of the boundary block from the vehicle at night, the light from the headlights of the vehicle hits the end face on the block side and is reflected by the driver to the pedestrian path. A walkway boundary block 15 with a reflector is generally used in which a reflector 12 is provided on the inclined surface 5 in a direction substantially perpendicular to the block longitudinal direction so that the existence of the boundary block can be easily recognized.

FIG. 6 shows an example of a conventional pedestrian road boundary block with a reflector.

FIG. 1A is a side view of a pedestrian boundary block 1 with a reflector, which has a large curved end surface 2 and a slanted surface 3, and is reflected by the slanted surface 3 (close to the longitudinal direction). A plate 12 is arranged.

FIG. 1B is a front view of the pedestrian road boundary block 1 with the reflector.

FIG. 5C is a side view of the pedestrian road boundary block 2 with a reflector in which the block side end surface is the inclined surface 5 as in the case of FIG. 5, and the concave portion 6 is recessed in the inclined surface 5 in the block longitudinal direction. It is a pedestrian road boundary block with a reflector plate having a structure in which a reflector plate 12 is provided on the substantially vertical surface of one end of the recessed portion 6 while being provided.

By providing the reflection plate 12 in the recess of the concave portion 6, even when a tire of an automobile rides on an inclined surface, the tire does not directly contact the reflection plate 12, and thus there is an advantage that it is not easily damaged. is there.

Further, since the lower surface 7 forming the concave portion 6 is not a horizontal surface but is inclined downward toward the outside, water and sand dust are not accumulated in the concave portion 6, and the reflecting surface is not polluted. It is a structure.

As shown in the perspective view of FIG. 4, the reflection plate 12 has a reflection surface 13 having a size of Y = 30 to 60 mm in length and X = 60 to 180 mm in width, and reflects light of yellow or orange color. It is a plastic reflector 12.

Further, as can be seen from FIG. 4, in the embedded type reflection plate 12, locking protrusions 17 for mounting and fixing are provided on the left and right of the reflection surface 13 so as to protrude in the direction opposite to the reflection surface. .

Upon installation, the reflector 12 is attached and fixed with a double-sided tape at a predetermined position inside the block mold, and then the concrete is poured and fixed easily.

Since the locking protrusion 17 is embedded inside the concrete block, it cannot be seen from the outside, and only the reflecting surface 13 is exposed.

Although the reflecting surface 13 is slightly perpendicular to the block longitudinal direction, the reflected light of the headlight (the height position is higher than the reflecting plate) is inclined to the elevation angle by tilting the vertical angle slightly to the back. Is set to.

[0016]

[Problems to be solved by the device]

 In the above-described conventional walkway boundary block 15 with a reflector, the main reflecting direction of the reflecting surface 13 of the reflecting plate 12 is a direction perpendicular to the reflecting surface (front reflection), so that the driving of an automobile facing the vehicle is performed. The matching of the position of the viewpoint of the hand and the reflected light from the reflection surface 12 of the headlight light is given only once.

In other words, the angle formed by the straight line connecting the eyes of the approaching car driver and the reflector and the horizontal line (assuming a horizontal road) fluctuates to gradually increase as the distance approaches, and The reflected light of the headlights from the board directly enters the driver's eyes only once.

In addition, seat positions are different between passenger cars, large trucks, and buses, and it is not unusual for the driver's eye height to differ by about 1 m.

Therefore, if there is only one reflector 12, the appropriate distance to be visually recognized does not change for passenger cars and trucks, and therefore the reflected light from the reflector of headlight light is recognized by the driver. At least one of the cars will be out of sync at the timing.

Although the above situation is related to the vertical direction, it will be clear that the same situation applies to the horizontal direction.

That is, the visible distance of the reflected light changes depending on the difference between the right steering wheel and the left steering wheel, and the change in the horizontal angle of the line connecting the driver of the car and the reflecting plate facing each other. You can see it only once.

The conventional pedestrian road boundary block with a reflector is not sufficiently safe in terms of visibility.

In this respect, in order to ensure safety, it is conceivable to provide a light emitting body such as a light bulb or an LED that is lit by a solar cell or an electric wire laying on the longitudinal end face of the pedestrian road boundary block instead of the reflector. The method has problems in terms of cost and maintenance.

Further, even though the reflection plate is embedded in the concave portion and is not easily damaged, it cannot be said that the reflection plate is damaged due to contact with a tire wheel such as a truck.

The present invention has been made in view of the above-mentioned circumstances, and two reflectors are attached to the side end faces so that the vertical angles and the horizontal angles of the two reflectors are different, and further, the reflections of the two reflectors are different. It provides a pedestrian road boundary block with a reflector that enhances visibility by changing the color of light while considering safety.

[0026]

[Means for Solving the Problems]

 The present invention provides (1) one end face in the longitudinal direction of the block is formed as an inclined surface or a curved surface, and a reflecting plate is provided on the inclined surface or the curved surface in the longitudinal direction of the block where the reflecting surface is horizontal. In a pedestrian road boundary block with a reflector, which is provided in a substantially vertical direction, the pedestrian road boundary block with a reflector is provided in which two reflectors are independently arranged above and below the side end face. (2) Further, in the pedestrian road boundary block with a reflection plate described in (1) above, the upper and lower reflection plates of the two upper and lower reflection plates provided on the inclined surface are provided so as to have different vertical angles with respect to the block longitudinal direction. By providing a pedestrian road boundary block with a reflector, which is characterized in that (3), in the pedestrian road boundary block with a reflector described in (1) or (2) above, the upper and lower parts provided on the inclined surface are provided. Of (4) Furthermore, by providing a pedestrian road boundary block with a reflector, characterized in that the reflecting surface of the projection plate is provided so that the left and right angles with respect to the block longitudinal direction are different, (4) Furthermore, according to (1) or (2) above. In a pedestrian road boundary block with a reflector, by providing a pedestrian road boundary block with a reflector, the reflected light colors of the upper and lower two reflectors provided on the side end faces are different from each other. It achieves the purpose.

[0027]

[Embodiment of device]

 An embodiment of a pedestrian road boundary block with a reflector according to the present invention will be described in detail with reference to the drawings.

The same portions as those in the conventional pedestrian road boundary block 15 with a reflector shown in FIG. 1 are denoted by the same reference numerals.

FIG. 1 is a perspective view showing the shape of a pedestrian road boundary block with a reflector according to the present invention.

FIG. 2 is a longitudinal sectional view showing a mounting state of two reflectors of a pedestrian road boundary block with a reflector according to the present invention.

FIG. 3 is a diagram showing the relationship between the headlight light and the light reflected by the reflector of the vehicle driver facing the pedestrian road boundary block with the reflector according to the present invention.

First, FIG. 1 is a perspective view showing the shape of a pedestrian road boundary block 30 with a reflector according to the present invention.

A different point from the conventional one is that two concave portions 6a and 6b are provided in two steps in the vertical direction on the inclined surface 5 of the end surface on the block side, and the reflection plates 12a and 12b are separately arranged on the substantially vertical surface at the back of each concave portion. It is in the place where it was set up.

It will be apparent that the arrangement of the two independent reflection plates 12a and 12b improves the visibility as compared with the conventional case.

Next, in FIG. 2, the vertical angles θ 1 and θ 2 which make the reflecting surfaces of the two reflectors 12 a and 12 b in the pedestrian road boundary block 30 with the reflector a line S perpendicular to the block longitudinal direction are different. Is shown (θ1> θ2).

In this case, as can be seen from FIG. 3, when the vertical angles θ1 and θ2 are distances L that are appropriate for the driver A and B of the vehicle approaching each other to recognize the boundary block, respectively ( A is a driver of a heavy-duty truck, B is a driver of an ordinary passenger car, and the heights H1 and H2 of each viewpoint are usually different from H1> H2.) Headlight D1, If the reflected lights R1 and R2 of D2 are set to enter, it can be said that the visibility is the best.

If there is only one reflector, there is a risk that any driver may not be visually recognized at an appropriate distance, but the above-mentioned configuration solves the problem.

Next, although the above-mentioned example is the case of the vertical angle of the reflecting surface, the same situation applies to the horizontal angle of the reflecting surface.

That is, the position of the driver is different depending on whether the vehicle is the right steering wheel or the left steering wheel, and the horizontal angle of the line connecting the opposing vehicle driver and the reflector changes every moment. With each reflector, the reflected light is good enough to enter the eye only once, and the visible distance changes.

Therefore, it is apparent that the right and left angles of the two reflectors 12a and 12b can be improved by appropriately setting them so that they are different from each other.

As described above, in the pedestrian road boundary block with a reflector according to the present invention, two reflectors are vertically arranged on the end face on the block side, and the vertical angle and the horizontal angle of both are preliminarily set at the time of manufacturing. It is set with consideration given to both passenger cars and trucks with different driver's eye height, so that the reflected light can be reliably reflected at an appropriate distance to be recognized (boundary block Existence) will be visible from any car.

In addition, the driver of the approaching vehicle receives the reflected light twice, so that the position of the pedestrian road boundary block can be identified more reliably.

Further, if the colors of the reflected light of the two reflectors are made different, the driver's consciousness is that the first reflected light is visually recognized at a distant position and the second reflected light is visually recognized at a closer position. Since it is clear, it is not difficult for the recognition of pedestrian road boundaries to become clearer.

Further, even if one of the two reflectors is damaged due to the contact of the longitudinal tire wheel, if the other is safe, temporary visibility is secured, so only one conventional reflector is used. It can be said that the safety is higher than the case.

It should be noted that the reflector used in the pedestrian road boundary block with the reflector may be a general-purpose one from the past, and in addition to the above-mentioned embedded type, it may be a type simply attached to the block with an adhesive (retrofitting type). Good.

As described above, the pedestrian road boundary block according to the present invention is provided with two reflectors attached to the end faces thereof, and by changing the vertical and horizontal angles of both reflectors and the color of the reflected light, the pedestrian road boundary block. It is an excellent device that dramatically improves the visibility of the.

[0047]

[Effect of device]

 Since the pedestrian road boundary block with a reflector according to the present invention is configured as described above, (1) the two reflectors are vertically arranged on the end face of the block, so that the visibility is one. It is higher than the case, and even if one of the reflectors is damaged, the other plays the role of reflection, so that it has an excellent effect of improving safety.

(2) Two reflection plates are arranged vertically on the end face on the block side, and the vertical angle and horizontal angle of both are set to different angles in advance at the time of manufacturing, so the reflected light should be recognized. It has the excellent effect that it can be seen from any car at an appropriate distance and that it enhances safety.

(3) Since the reflected light enters the eyes of the driver of the approaching vehicle twice, it has an excellent effect that the position of the pedestrian road boundary block can be more reliably identified.

(4) If the colors of the reflected light of the two reflectors are made different, the first visual recognition of the reflected light at a distant position and the second visual recognition of the reflected light make the driver's recognition clear. Therefore, it has an excellent effect that the recognition of the boundary of the pedestrian road becomes clearer.
