TECHNICAL FIELD OF THE INVENTION
The present invention relates to a curb installed along a boundary of a roadway of a road, and in particular, a curb provided with a reflecting plate so that a driver such as an automobile can easily recognize the boundary of the roadway at night. About.
[0002]
[Prior art]
In order to clearly divide a roadway from a sidewalk or a side road, a curb is often installed along the boundary of the roadway. In order to make it easier for a driver such as an automobile running on the road to recognize the boundary of the road even at night, a reflector may be provided on the curb.
[0003]
Hereinafter, a conventional configuration example of such a curb will be described with reference to the drawings. FIG. 8 is a sectional perspective view showing an installation state of a curb according to a conventional example.
[0004]
In this conventional example, a sidewalk 12 is provided one step higher along the end of the roadway 10. The curbs 14 are arranged in a row along the corner of the sidewalk 12 and the boundary with the road 10.
[0005]
The curb 14 is a concrete member having a substantially L-shaped cross section in a direction perpendicular to the longitudinal direction. The curb 14 has an upper surface 16 arranged along the edge of the road surface of the sidewalk 12, and a step surface between the sidewalk 12 and the road 10. , And a side surface 18 facing the roadway 10. A reflection plate 20 is provided on the side surface 18.
[0006]
As described above, when the reflector 20 is provided on the side of the curb 14 installed along the boundary of the road 10 facing the road 10, the light of the headlight of the automobile or the like is reflected at night by the reflector 20. Therefore, the driver can easily recognize the boundary of the road 10 and greatly helps prevent a traffic accident.
[0007]
[Problems to be solved by the invention]
However, when the reflector 20 is provided on the side surface 18 of the curb 14 like the curb 14, the reflector 20 is disposed at a low position that is not much different from the road surface of the road 10, so that the vehicle is traveling on the road 10. It is difficult for a driver of a car or the like to visually recognize a reflector far away. In addition, a large amount of sewage and dust splashed by an automobile or the like running on the roadway 10 is likely to adhere to the reflector 20, which may significantly deteriorate the visibility (reflectivity) of the reflector 20. Further, pebbles and the like scattered by traveling of an automobile or the like may hit the reflecting plate 20, and the reflecting plate 20 may be damaged.
[0008]
Moreover, when cleaning, checking, and repairing the reflecting plate 20 provided on the side surface 18 of the curb 14, the worker performs these operations with a considerably low bent position, and the working posture is cramped. . For example, when performing these tasks from the sidewalk 12 which is one step higher than the roadway 10, the worker must reach out even below his / her feet.
[0009]
The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a curb in which the visibility of the reflector is good and the reflector is less likely to be stained or damaged.
[0010]
[Means for Solving the Problems]
The curb of the present invention is a curb installed on a road, a curb main body, a convex portion protruding upward from an upper surface of the curb main body, and a reflector provided on at least a part of a side surface of the convex portion. In the curb provided with, the attached body is provided from the upper surface of the curb main body to one side surface, and the attached body is integrally provided with the convex portion , and the attached body is an integral ceramic including the convex portion. It is characterized by being manufactured.
[0011]
In the curb according to the present invention, since the reflector is provided on the protrusion protruding upward from the upper surface of the main body of the curb, it is disposed at a position considerably higher than the road surface of the road. For this reason, a driver of an automobile or the like traveling on a roadway can easily visually recognize a reflector of a curb farther than a conventional curb. In addition, dirty water, dust, pebbles, and the like splashed by a running vehicle or the like are unlikely to hit the reflecting plate, so that the reflecting plate is less stained and the reflecting plate is prevented from being damaged. Furthermore, when performing work such as cleaning of the reflector, the worker does not need to bend down too low, and can work in a comfortable posture.
[0012]
In the curb according to the present invention, the protrusion has a first side surface extending in the longitudinal direction of the curb main body, and a second side surface extending in a direction substantially orthogonal to the longitudinal direction, and at least a road. It is preferable that reflection plates are provided on the first side surface on both sides and on both second side surfaces. With this configuration, not only the first side surface on the road side but also the second side surfaces orthogonal to the first side surface are provided with the reflectors, so that the visibility of the reflectors is extremely good.
[0013]
In the present invention, a reflection plate may be further provided on the first side surface on the sidewalk side of the projection. This makes it easy to visually recognize the reflector even from a bicycle running on the sidewalk.
[0014]
In addition, when the reflection plate is also provided on the first side surface on the sidewalk side of the convex portion, the reflection plate provided on the first side surface on the roadway side of the convex portion due to a sharp curve, for example. Even if the light is not reflected from the headlights of the vehicle due to being on the back side (facing side) of the convex portion when viewed from the traveling vehicle, the reflectors provided on the first side surface and the second side surface on the sidewalk side respectively have heads. Since the light is reflected, the driver can clearly see the position of the curb.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
[0016]
FIG. 1 is a perspective view of a curb according to an embodiment of the present invention, and FIGS. 2 (a) and (b), FIGS. 3 (a) and (b), and FIGS. 4 (a) and (b). ) Are a top view, a bottom view, a front view, a rear view, a left side view, and a right side view of the curb, respectively. 5 and 6 are sectional views taken along lines VV and VI-VI in FIG. 3 (a), respectively, and FIG. 7 is a sectional view taken along line VII-VII in FIG. 2 (a). It is sectional drawing which follows.
[0017]
The curb 30 has a curb main body 31 made of concrete or the like, and an attached body 40 arranged from the upper surface of the curb main body 31 to one side surface.
[0018]
The attachment body 40 has a substantially L-shaped cross section in a direction orthogonal to the longitudinal direction, and has an upper surface 44 extending in the horizontal direction, and a side surface 46 hanging down from one longitudinal side of the upper surface 44. Is provided. At an intermediate portion in the longitudinal direction of the upper surface 44 of the base portion 42, a convex portion 48 protruding upward is provided. The base portion 42 and the convex portion 48 is formed on the thus integrally with ceramic.
[0019]
The convex portion 48 has a pair of first side surfaces 50, 51 extending in the longitudinal direction of the base portion 42, that is, the longitudinal direction of the curb body 31, and extends in a direction orthogonal to the first side surfaces 50, 51. It has a substantially trapezoidal shape having a pair of second side surfaces 52, 53. The first side surfaces 50, 51 and the second side surfaces 52, 53 have reflectors 54, 55, 56, 57, respectively. Is provided.
[0020]

However, in order to protect the reflecting surface, the convex portions 48 are provided. The surfaces of the reflection plates 54 to 57 may be provided so as to be depressed from the surface.
[0021]
The upper surface 44 of the attachment 40 is flush with the upper surface of the curb body 31, the side surface 46 is flush with the side surface of the curb body 31, and the projection 48 projects upward from substantially the center of the upper surface of the curb body 31. I have.
[0022]
Similar to the curbstone 14 shown in FIG. 8, the curbstones 30 are arranged in a row along the corners of the sidewalk that is provided one step higher along the edge of the roadway. The curb 30 is arranged such that the upper surface of the curb main body 31 is arranged along the edge of the road surface of the sidewalk, and the side surface faces the road along the step surface between the sidewalk and the road.
[0023]
In the curb 30 thus installed, the reflectors 54 to 57 are arranged at a position considerably higher than the road surface of the roadway as compared with the conventional curb. Therefore, a driver such as a car traveling on a roadway at night can clearly see even the reflectors 54 to 57 of the curb 30 that are relatively far away. Also, it is rare that sewage water, dust, pebbles, etc., splashed by a running automobile or the like fly up to and hit the reflectors 54 to 57, and the reflectors 54 to 57 may be significantly deteriorated in visibility due to dirt or damage. Absent. Then, when performing operations such as cleaning and inspection of the reflection plates 54 to 57, the worker does not need to bend down so much, and can perform these operations in a relatively comfortable posture.
[0024]
In addition, in the curb 30, since the first side surface 51 on the sidewalk side and the second side surfaces 52, 53 are also provided with the reflection plates 55, 56, 57, respectively, for example, the vehicle is running on a road. When the car approaches a sharp curve, the reflector 54 of the first side surface 50 facing the roadway of the curb 30 from the middle of the curve is located on the back side (the side facing away) when viewed from the car. Also, the reflector 55 facing the sidewalk side and the reflectors 56 and 57 facing the direction orthogonal to the reflector 54 reflect the light of the headlights, respectively, so that the position of the curb 30 can be clearly recognized by the driver. it can. As a result, the driver can accurately grasp the situation ahead of the road, and can perform calm and safe driving without panic even on a sharp curve.
[0025]
Further, in the curb 30, the reflection plate 55 is also provided on the first side surface 51 on the side of the side of the protrusion 48, so that, for example, the light of the light of the bicycle running on the side at night is reflected. Then, the rider of the bicycle can visually recognize the boundary of the sidewalk. Thus, it is possible to prevent the bicycle running on the sidewalk from falling onto the road at night. Since the reflectors 56 and 57 of the second side surfaces 52 and 53 also reflect the light of the bicycle light, the boundary of the sidewalk is very easy to understand.
