Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a post sticking reflector that is attached to a post of a traffic safety facility such as a curve mirror, a sign post or a road fence.
[0002]
[Prior art]
Conventionally, a reflector attached to this type of support has been directly applied to the surface of the support by an adhesive layer formed on the back surface of a reflective tape that has been treated with fine glass beads on its surface. There is generally something affixed. In addition, a flat plate shaped body with large glass beads embedded at regular intervals as shown in FIG. 4 is fixed to the column with screws or rivets, and receives the light from the vehicle coming from one direction and retroreflects. There is something to let you do.
[0003]
[Problems to be solved by the invention]
However, when this support tape is newly installed in a traffic safety facility or the like, since the support surface is smooth and free from dirt, it does not peel off closely, but the reflective sheet is used to add a reflective function to the existing support post. If attached, the surface of the support surface is roughened and the surface becomes rough, resulting in insufficient adhesion of the reflective tape. If any gap is left, rainwater will enter and gradually peel off. There is. Accordingly, there is a problem that the durability of the reflective tape is inferior in durability.
[0004]
In addition, since the reflective tape is wound around a curved surface such as a support column, the reflective surface becomes a curved surface, and light irradiated from one direction is exposed to light from an oblique direction in most projection areas. However, in the reflective tape, light coming from a direction perpendicular to the reflective surface is most effectively retroreflected, and the retroreflective function inevitably deteriorates as the incident angle increases. Therefore, the projected area of the reflection sheet wound around the support becomes a strong reflected light and is not recurred. Further, the surface is easily damaged, and even if a small amount of dirt adheres to the surface, the brightness is lowered and visibility is deteriorated.
[0005]
On the other hand, the molded body in which the prism or the large glass beads are embedded may be improved in visibility because the light of light irradiated from one direction is efficiently retroreflected, but the prism or the molded body is unidirectional. In order to retroreflect the vehicle coming from the upper and lower lines of the road, multiple reflectors are pointed in each direction and the installation angle is fully considered. It will be necessary to install it above. In addition, the mounting work is troublesome when screwing, and the attached reflectors are not coherent and unsightly in design.
[0006]
Therefore, the present invention solves such problems as described above, and can be retro-reflected individually to vehicles coming from each direction of the route, and the reflection luminance is set to an efficient angle and easily attached to a column or the like. It is intended to provide a reflector for sticking a support.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows. That is, the post sticking reflector according to the present invention is attached to a post such as a road facility, and a reflection surface directed in each direction of the route is formed on the surface of the main body by a plurality of retroreflection groups, and the retroreflection group Each of which is directed to the optical axis in the same direction, the back side of the main body surface is a reflector for post sticking that has a concave shape that complements the post curved surface , the cross-sectional shape is substantially trapezoidal, One side forming the base of the trapezoid has a concave shape that is in close contact with the outer shape of the column as a mounting surface, and a reflecting surface is formed on the surface of the main body that forms the other three sides .
[0008]
According to the present invention, a reflective surface that independently retroreflects toward each route direction is formed on the surface of the main body, and the reflective surface includes a plurality of retroreflective groups that are directed in the same direction of the optical axis. When attached to a curved mirror post or the like standing on the shoulder of a T-junction, the reflecting surface is directed to the vertical line of the road and the branch road, and the reflected optical axis is fixed in the same direction. Even if the vehicle approaches from the direction, all the light emitted from one direction is totally reflected by the reflecting surface, and is reflected in the same direction as a strong light bundle.
[0009]
Moreover, since the back side of the surface of the main body forms a concave surface that complements the curved surface of the column so as to be in close contact with the wall surface of the column, no backlash occurs. Normally, the shape of the column used for traffic safety facilities is a round pipe, and the outer diameter is limited to approximately 4 types of 60.5, 76.3, 89.1 or 114.3 millimeters. If it is molded into a concave shape suitable for each outer diameter, there will be no practical problem.
[0010]
Further, the reflection surface is composed of a group of glass beads in which a large number of glass beads are arranged at intervals, and each glass bead of the glass bead group is molded by being half-immersed on the surface of the main body, or the glass bead group is A semi-submerged reflecting plate is formed by fitting on the surface of the main body. That is, since the reflection optical axis of each glass bead of the glass bead group is formed in the same direction and the reflection surface is opposed to each route direction, the light of the headlight hitting the glass bead group is It receives light at a right angle to the reflecting surface and returns strong light. And even if the angle which light-receives on the said reflective surface shifts a little as a vehicle approaches, it can maintain in the range which does not reduce reflection luminance. As the glass beads used in the present invention, for example, large glass beads having a particle diameter of about 2 to 10 millimeters are preferably used, and the glass beads are regularly arranged with a certain distance without contact between the glass beads. It can be firmly fixed to the surface of the main body and it is difficult for dirt to adhere to it. Further, the retroreflective brightness is increased.
[0011]
On the other hand, it is technically difficult in the manufacturing process to dispose large glass beads on each of the polygonal surfaces formed by the reflecting surface, so a reflecting plate formed by arranging glass beads in a flat shape is retrofitted to the surface of the main body. A process may be taken. If the reflector can be attached to the surface of the main body by a retrofitting process, it is easy to omit the reflecting surface at an unnecessary angle where it is necessary to retroreflect only in both directions of the lane. In addition, at a complicated branch point, a plurality of them can be appropriately attached at an angle facing each route direction. The reflector does not necessarily need to be formed of a group of large glass beads. For example, a prism molded body or a reflector having a retroreflection function such as a high-intensity reflection sheet can be used.
[0012]
Further, an adhesive layer may be formed on the concave surface forming the back side of the main body surface, and the adhesive layer may be directly adhered to the side surface of the support. The adhesive layer is formed in a form in which a double-sided adhesive tape that adheres strongly is attached to the concave surface, or the adhesive is mechanically processed on the concave surface and protected by a release paper before use. Also good. The adhesive layer should be designed to increase the coating thickness and increase the adhesive strength so that the adhesive strength does not decrease even if the column surface is slightly rough. However, since this adhesive layer is outdoor specifications, it is necessary to select a material that fully considers water resistance and durability.
[0013]
In this way, it can be easily attached to new construction of traffic safety facilities, existing pillars, etc., and the light of cars approaching from each direction is efficiently retroreflected to guide the line of sight, or curved mirrors and roads The presence of a sign or the like can be easily recognized, thereby obtaining an effect of gazing at a curve mirror or a road sign.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be specifically described with reference to the drawings.
First, FIG. 1 is an installation view (a) and a partially enlarged perspective view (b) showing a state in which an embodiment of the present invention is attached to a column. FIG. 2 is an explanatory view showing the installation state of FIG. FIG. 3 is a front view and a top view showing several examples of another embodiment of the present invention. FIG. 4 is a perspective view showing a conventional embodiment, in which (a) is a belt-like reflector and (b) is a disk-like reflector.
[0015]
1 and 2 will be described in detail. The reflector 1 for post sticking of the present invention has a substantially trapezoidal cross-sectional shape, and is molded into the round shape of the post 3 so that one side forming the base of the trapezoid is in close contact with the outer shape of the post 3 as the mounting surface 2. The reflecting surface 4 is formed on the surface of the main body forming the other three sides. Further, an adhesive layer 21 is formed on the mounting surface 2 and is protected by a release paper until it is attached to the column 3.
[0016]
The reflective surface 4 has large glass beads 4a arranged on a plane at regular intervals, and reflectors 41, 42, and 43, which are integrally molded leaving a head, are fitted on each surface of the main body surface. 4 is formed. The angles of the reflection plates 41, 42, and 43 forming the reflection surface 4 are expanded by 60 degrees from the central reflection plate 42 to the left and right to form the reflection plates 41 and 43. That is, when the light of a vehicle traveling in the lane hits one of the reflecting plates 41, 42, 43 in the vertical direction, the light is most effectively retroreflected and within 15 degrees around the optical axis. Even if it shakes, the retroreflected light does not fade, but the reflected luminance gradually decreases as the angle further changes. Therefore, the angle is set so that the reflecting surface 3 faces in the direction in which the vehicle is located within the range of the deflection angle of 30 degrees with respect to the optical axis of the reflector.
[0017]
More specifically, the post sticking reflector 1 of the present invention is attached in the middle of the post 3 to which the curve mirror 31 is attached, and the reflecting surface 4 in the direction of the upper and lower lanes a and b projected to the carp mirror 31 and the branch road c. Reflective plates 41, 43 and 42 are oriented in the respective route directions. The car coming from the branch c direction always emits strong retroreflected light because the light strikes the reflector 42 located at the center of the main body at right angles and without shaking until it approaches, and the cars in the upper and lower lanes a and b are respectively Is set at an angle that is bent 60 degrees outward from the central reflector 42 so that the right and left lights strike the reflectors 41 and 43 on the left and right sides of the main body at substantially right angles. That is, the reflection plate 42 in the central portion forms a parallel plane with respect to the vertical road, and the left and right reflection surfaces 41 and 43 are formed at an angle expanded 60 degrees from the parallel plane. The headlight light L1 emitted from a distance of 80 meters from which light reaches when the light is set downwards, the deflection angle to the light L2 of the headlight when approaching almost immediately is centered on the optical axis of the reflecting surface And within 30 degrees, good retroreflected light can be obtained. In this way, the driver knows the existence of the curve mirror from a distance, and pays attention to the image projected on the curve mirror.
[0018]
FIG. 3 is a front view and a top view showing several examples of another embodiment of the present invention, and adjusting the size and arrangement of the reflectors attached to the reflecting surface formed at different angles on the surface of the main body. Thus, the reflection luminance is increased. In other words, all the large glass beads placed on the reflector have the optical axis in the same direction and are designed to efficiently retroreflect the light. Therefore, the larger the large glass beads group, the larger the reflected light is. Become recursive. Accordingly, the amount and size of the reflector are appropriately selected so that the reflected luminance can be changed with respect to the priority road or priority route of the route or depending on the brightness of the surrounding illumination.
[0019]
The substrate for forming the reflector for sticking a support of the present invention is flexible, such as polyethylene resin and ABS resin, is strong against impact, has excellent weather resistance, and holds glass beads to protect the glass beads themselves. Sufficient resin is selectively used. The color of the substrate is not particularly limited, but black is preferably used in consideration of weather resistance, retroreflectivity, visibility, and the like. The glass beads used here are mirror-finished by vapor deposition plating on the half of the sphere, so that the light incident on the glass beads can be obtained by molding the mirror part half-embedded in the base material. It is totally reflected at the mirror surface and is efficiently recurred without being affected by the color of the substrate itself. Furthermore, the glass beads may have a true sphere shape, but considering the refractive index of the glass beads, the headlight light can be retroreflected without waste if it is an atypical sphere whose focal point is just a spherical surface. It is still preferable.
[0020]
Further, when glass beads are used as the reflector, a part of the glass beads are exposed and embedded on the surface of the base material, so that light coming obliquely can be taken in and retroreflected. Therefore, a wide light receiving angle of the headlight can be taken, and even if it receives light from a wider angle, it is retroreflected. Furthermore, since the surface of the glass beads that receive light is smooth and hard, dirt is difficult to adhere and is easily removed.
[0021]
【The invention's effect】
It can be easily attached to the side of the pillar where a road curve mirror etc. is installed, and it effectively receives the light of the headlight irradiated from each direction and reflects it as a strong light retroreflecting, so there is a line-of-sight effect It is expensive and avoids contact with and collision with the column, and at the same time, the presence of the curved mirror can be recognized even from a distance, so it is possible to drive safely by carefully checking the image of the curved mirror. Therefore, a traffic accident can be prevented beforehand.
