Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector for mounting on a wall surface, which is easily and reliably mounted at low cost on a side wall of a road and provides visibility at night.

[0002]

2. Description of the Related Art Conventionally, for example, on a side wall of a highway or the like,
The reflector is attached to a main body made of metal, synthetic resin, or the like, and a plurality of the main bodies are attached to the side wall with bolts or an adhesive. Such a reflector uses a prism, glass beads or a reflection sheet, is provided with an appropriate angle so that the light of the car is retroreflected, and is fixed to the main body with concave and convex fits or screws or an adhesive, and is attached to the wall surface. A hole was previously drilled with a concrete drill and screwed using, for example, an anchor bolt, or surface-bonded chemically with a two-component curable adhesive such as epoxy resin, or the main body was previously attached to the side wall. A method of fixing the reflector to the main body later is known.

[0003]

However, since the reflector has a structure in which the main body and / or screws are made of metal or a composite material of different kinds of resins, the material procurement and inventory management are not performed. Not only is it complicated, but it is difficult to reduce the material cost because it is manufactured through complicated steps such as fitting and screwing in the manufacturing process.

[0004] In addition, when installing on a side wall of a highway or the like, it is necessary to complete the construction in a shorter time more efficiently under traffic regulations. Work has to be performed, the work time is prolonged, and the installation cost is increased due to the necessity of mounting members.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and to reduce the cost of the product, and to provide a reflector for mounting on a wall surface, which can be easily and firmly mounted on a road side wall.

[0006]

In order to achieve the above object, according to the present invention, a plate and a leg which stands vertically on the back surface of the plate are formed integrally with each other. It is preferable that a reflector that reflects light retroreflectively be formed on the surface of the device. By integrally molding the legs, productivity is improved and costs are reduced.In installation work, openings such as holes and grooves are provided in walls such as expressways to fasten bolts and other fastening members. The body can be easily attached to the wall surface by inserting or press-fitting the legs without using it, and the retroreflective function by night light can be obtained because the reflector is formed on the surface of the plate.

On the surface on which the reflector is formed, a large number of V-shaped grooves having an engraving angle of at least 90 degrees or more are juxtaposed and juxtaposed, and the reflector is formed on one wall in one direction of each of the V-shaped grooves. It is preferable that the reflector is buried and has an optical axis perpendicular to the one wall surface. When attaching the main body of the present invention to a wall surface, the V-shaped groove formed on the surface of the plate body is oriented in the vertical direction, and the reflector is fixed in the light direction of the car,
The plate close to the wall receives light at a thin oblique angle with respect to the direction in which the car travels, but a reflector is embedded in one wall of a V-shaped groove carved on the surface of the plate. So
The light of the car is retroreflected substantially in accordance with the light receiving angle and the radiation angle of the reflector.

The reflector may be formed in an intermittent row of a V-shaped groove. That is, when the surface of the plate is irradiated with light at an extremely thin angle, for example, when receiving the light of a car traveling close to the side wall, the light is buried in one wall of the V-shaped groove. Since the reflector that has been hidden or overlapped by the peak of the V-shaped groove, efficient retroreflection in proportion to the number of reflectors is not performed. Therefore, it is preferable that the formed reflectors are not buried in one row of the V-shaped groove in all rows but are formed in intermittent rows at least every other row.

In addition, the form of retroreflecting light received from a thin wall surface is not necessarily a form in which a reflector is buried in a mold wall having a surface shape adjacent to the V-shaped groove. May be curved, and a reflector such as a burrism or a reflection sheet may be formed on the surface. Since this curved surface can receive and irradiate the light irradiated at a thin angle on the wall surface, it can be retroreflected.

The legs may be formed in a plate shape or a cylindrical rod shape. The leg is integrally formed with the plate, but the plate-shaped leg and the plate are integrally formed into an elongated shape by, for example, extrusion molding, and the plate is cut into a predetermined size to obtain a plate. A reflector may be formed on the surface of the substrate, and, for example, a rod-shaped leg and a plate may be integrally molded by injection molding, and the reflector may be molded simultaneously or formed in another process.

When the leg is formed in a plate shape and has a T-shaped or L-shaped cross section, for example, a groove can be cut into a wall surface by a cutter or the like, and the plate-shaped leg can be inserted or press-fitted and attached. Alternatively, if a part of the plate of the leg is cut out to form a rod, the rod-shaped leg can be inserted or press-fitted into a hole formed by drilling the wall surface.

The leg may be formed, for example, as a single cylindrical rod at the center of the back surface of the plate, or a plurality of rods may be erected. However, since it is necessary to drill with a drill according to the number of the legs when mounting on a wall surface, it is preferable that two legs are formed in consideration of workability at the site and deviation after installation. Good. The length of the leg is preferably set in consideration of the holding force of the main body and the work of processing the wall surface. When the legs are inserted or pressed into the wall surface, for example, by injecting a two-liquid epoxy resin or the like into the holes in the wall surface in advance, the holding force of the legs is increased and the legs can be firmly attached.

[0013] Further, it is preferable to form a concave-convex locking portion at the tip and / or intermediate portion of the leg. When the leg is inserted by cutting a hole or groove on the wall surface, the convex and concave portions of the leg are required to be wider than the hole or groove, and the convex is pressed into the hole or groove to converge. The recess may be formed, or the protrusion may be deformed and accommodated. With such a configuration, by pressing the legs into the perforations or grooves formed in the wall surface, it is possible to quickly and firmly fix without using an adhesive. Also, the adhesive may be used together to more firmly attach. It is to be noted that a groove-like concave portion is provided in a part of the leg portion without a convex portion.
It may be physically locked by injecting and solidifying a liquid-curable adhesive or the like.

The material of the integrally formed product is not particularly limited, but is generally polyolefin resin, ABS resin, SBR resin, urethane resin, polycarbonate resin, vinyl chloride acrylic copolymer resin, ethylene It is made of a synthetic resin such as vinyl acetate copolymer resin or a metal such as aluminum die cast.

Next, an embodiment of the present invention will be specifically described with reference to the drawings. First, FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a cross-sectional view in which the embodiment is mounted on a wall surface and is an explanatory diagram. FIG. 3 is a perspective view showing a modified embodiment of FIG. 1. (A) shows an intermittent form in which a groove array to which a reflector is attached, and (B) shows a form in which a groove interval is widened. It is. FIG. 4 is a perspective view showing another embodiment of the present invention, in which (A) is a plate-like leg, (B) is a rod-like leg with a part of the plate cut away, (C) shows an example in which a curved reflector is attached. FIG. 5 is an installation sectional view in which an example of a locking structure is formed on a leg and attached to a wall surface.

In FIG. 1 and FIG. 2, a plate 1 and a leg 2 that stands vertically on the back surface of the plate 1 are integrally formed, and a right angle of engraving is formed on the surface of the plate 1. A plurality of reflectors 4 are buried side by side in one direction of each V-shaped groove 3, and the reflectors 4 are buried in the one-side wall 31. It is fixed so that it becomes a vertical optical axis.

The mounting structure is such that a hole A1 slightly larger than the leg portion 2 is formed in the wall surface A, the post-adhesive B is injected, and the leg portion 2 of the present invention is inserted and solidified. At this time, the adhesive B is filled in the concave groove 21 provided in the leg portion 2 to perform an anchoring effect and prevent the groove from coming off. The reflector 4 attached in this manner is formed at an angle at which the reflector 4 is retroreflected when receiving light a from an oblique direction with respect to the wall surface. Even if the light of the traveling car is illuminated at a shallow angle to the plate 1, the light axis of the reflector 4 is directed to the direction of the light of the car. Visibility can be given.

However, the angle of the light illuminating the plate 1 may be extremely small depending on the right and left curves. In such a case, the groove row shown in FIG. It is preferable to adopt a form in which a reflector is provided or the V-shaped groove (b) is formed with a wide space.

FIGS. 4A and 4B show a case where the leg 2 is integrally formed with the plate 1 on which the reflector 4 is formed. The T-shaped extruded main body is cut into strips, and a separately molded reflector 4
Are joined or fitted to the surface of the plate 1 to be integrated. The reflector may be formed in the shape of the V-shaped groove so as to correspond to oblique incident light, or may be a curved reflector capable of responding to light in multiple directions as shown in (c). A reflection sheet may be attached. Therefore, the reflector 4 attached to the surface of the plate 1 is not particularly limited in shape and material.

Further, the form having the plate-like legs 2 can be easily mass-produced by extrusion molding, but it is necessary to form a groove by grinding with a concrete cutter or the like when mounting on a wall surface. In (b) of FIG. 4, a part of the plate shape of (a) may be cut into a bar shape so as to be easily applied to a hole formed by drilling. Such a configuration is excellent in productivity, can greatly reduce the cost, and does not require a mounting member.

Further, in the leg of another embodiment shown in FIG. 5, a convex locking portion 21 is formed at the tip of the leg 2, so that the leg is formed in a hole in the wall surface. The press-fitting deforms the locking portion so as to stretch the inner wall of the hole and prevent the hole from coming off.

[0022]

Since the plate on which the reflector is formed and the legs attached to the wall are integrally formed, the productivity is excellent, the quality can be secured and the production cost can be reduced. In addition, since fastening to a wall surface does not require a fastener and can be performed extremely simply and reliably, the time and labor required for construction can be reduced, and the total cost can be reduced.
