Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaze guidance sign that is installed on a roadside or a median strip of a road and guides a gaze by reflecting light of a headlight with respect to traffic of vehicles at night.
[0002]
[Prior art]
Line-of-sight guides installed on the roadside and median strips of the road are conventionally provided with a reflector on top of a steel pipe as a support, and the light irradiated to the car light is retroreflected by the reflector, and the driver is on the roadside In addition, it is designed to recognize the position or alignment of the median strip and drive safely. The reflector is generally a reflector using a prism, a reflection sheet provided with fine glass beads, a buried type of large glass beads, or the like. These vary in size, shape, color, number, etc., and are reflected to enhance visibility in areas where the traffic is used, especially in areas that call attention, such as heavy traffic, sharp curves, and intersections. A lot of body is attached or a larger reflector is used.
[0003]
On the other hand, for example, an aluminum mold material having a complicated cross-sectional shape described in Japanese Utility Model Application No. 9-007428 is used as a support column body, and a number of sign bodies that are erected on the roadside and the median strip are integrated into a reflector or sign. There is disclosed a multifunctional gaze guidance mark in which a plate or the like is appropriately fitted and fixed.
[0004]
In addition, these conventional line-of-sight guide signs are made with a strong emphasis on traffic safety and durability, the columns are made of metal such as steel pipes or aluminum molds, and the members such as reflectors are made of different types of synthetic resins. Or a glass bead molded body, and is fastened with a metal member or fixed with a strong adhesive.
[0005]
[Problems to be solved by the invention]
However, since the gaze guides as described above are all made of metal, the base is destroyed or bent when the car comes into contact with it, and the reflector is not restored due to impact or deformation of the post. As a result, the original function was lost at that time, and there was a fear that various vehicles and traffic would be hindered. Once the reflector is dropped, the structure cannot be restored on site, so it must be replaced with a new one along with the column. As a result, there was a problem in terms of the cost burden associated with removal and new installation work in addition to being unable to respond promptly while agile response was required. In addition, a molded body having a complicated cross-sectional shape such as an aluminum mold material of the support main body is difficult to mold and does not have a dimensional accuracy for fitting, so that the yield is reduced and the cost is increased.
[0006]
Further, the conventional line-of-sight guidance mark is formed of a composite material composed of a metal member and several kinds of synthetic resins, including replacement of a support column, and has a structure that cannot be easily disassembled even if they are separated and collected. For this reason, they cannot be recycled, and are discarded as bulky garbage without effective utilization of resources.
[0007]
Therefore, the present invention is intended to solve such conventional problems and provide a visual guidance indicator that functions effectively in practice and can be recycled.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows. That is, the line-of-sight guide mark according to the present invention is fitted in the concavo-convex groove formed in the column main body and is engaged with the engagement wing of the holding body having the engagement wing so that the reflector can be inserted vertically. The cap is attached to the upper end of the column main body, and the stopper is fixed to the lowermost edge of the reflector, and the reflector is sandwiched and stopped.
[0009]
In the column main body, two opposing outer peripheral wall surfaces of the hollow cylindrical body are both flat, both end edges of the plane portion protrude in a rib shape, and an uneven groove is provided in the central portion to form the column main body. Such a column main body has a simple shape without undercut and has been considered for improving the moldability. A holding body having locking wings is fitted into the concavo-convex groove and fixed by adhesion or screwing. In this way, the support body is provided with the locking wings, and the reflector having the back surface shape adapted to the locking wings is locked, and the ribs are narrowed to the left and right to allow insertion. In this way, the holding body is arbitrarily fixed vertically and front and back along the concave and convex grooves, and the number of reflectors, the color, and the shape are appropriately changed so as to be arranged efficiently. Thereafter, a cap is placed on the upper end of the support body so that the reflector does not come out, and a reflector that is loosely fitted with a stopper attached to the bottom of the reflector is provided.
[0010]
The reflector is loosely fitted and sandwiched between the cap and the stopper so that the reflector can be easily removed by removing the cap, and separation and recovery can be performed when replacing or recycling the reflector when it is damaged. Considerations that can be made easier.
[0011]
On the other hand, the holding body may have a reflector on the back surface, the abdominal surface forms a vertically split half surface shape of the cylindrical column main body, and a pair of them are embraced and fitted to the column main body so as to be freely inserted. This holding body has a latch on the back surface to which the reflector is fitted, and a fitting portion is formed on the joint surface where the pair is assembled so as to be hugged to the column main body. The reflector does not necessarily have to be attached to the back surface of the holding body. If the line-of-sight guide mark of the present invention is a single-sided type, the reflector does not have to be attached to one side of the pair of holding bodies. In addition, since the holding body can be inserted into the column main body so that a plurality of gaps are provided between the plurality of connected column bodies, even if the column main body is greatly bent, it is held loosely between the cap and the stopper. . When the column main body is cylindrical, a holding portion may be provided on the overlap portion of the holding body and the holding portion overlapping portion of the cap and the stopper so that the pair of holding bodies do not rotate, and may be engaged with each other. This is not necessary if the column body has a deformed cylindrical body having a catch.
[0012]
The material of the column body may be steel or aluminum mold material, but at least the column body is made of thermoplastic synthetic resin, giving the column flexibility and causing rebound resilience even if it touches a car or a person. By restoring to the original state, damage may be minimized. The column main body is suitably made of, for example, thermoplastic synthetic resin such as polyethylene, polypropylene, ABS resin, AAS resin, vinyl chloride resin, polyurethane resin, and thermoplastic polyester as a flexible, impact resistant, moldable, and inexpensive resin. . In addition, since the reflector receives light and retroreflects it, a hard resin that is highly transparent and hard to be damaged is selected. For example, an acrylic resin, a polycarbonate resin, a methacrylic resin, or glass is used. Therefore, the column main body and the reflector must be used together as different materials, and can be separated and collected by being removed by the fitting structure. The cap is screwed with a screw and can be removed when the reflector is repaired or recycled.
[0013]
Furthermore, at least the support body and the support body may be formed of the same thermoplastic synthetic resin. For example, if polyethylene is used, heat fusion by ultrasonic waves is possible, and the support body is easily and firmly bonded to the support body. It can be made. Therefore, the holding body is unevenly fitted into the concave and convex grooves of the column main body, and is fused and integrated completely, and the reflector is reliably positioned by accurately positioning in the width direction of the column main body. It can be locked in between. By using the same resin in this way, it can be integrated without screwing, so that separate collection becomes more advantageous.
[0014]
In addition, in the reflectors disposed above and below the column main body, it is preferable that the holding body is fixed across the lower edge of the upper reflector and the upper edge of the lower reflector. The reflector is regulated in the lateral direction by the ribs of the column body, and is narrowed in the vertical direction by the cap and stopper, and then the reflector is loosely fitted to the retaining wings of the holder and engaged with the column body. Since it is stopped, the column main body bends, and thus a deviation occurs at the joint of the reflector, but the edge of the reflector is locked so that it does not jump out and come off. Therefore, the column main body can be bent while the reflector is securely held. Therefore, when the line-of-sight guide mark of the present invention is erected, the reflector protrudes even if it is swung by a slight impact or contact. Restore without.
[0015]
In addition, the protrusion side in which a steel pipe can be freely inserted may be formed in the longitudinal direction on the inner wall portion of the cylindrical body forming the column main body. Since the column body swings when it is made of thermoplastic synthetic resin, it can be rigidly installed by removing the cap and inserting the steel pipe in places where it is necessary to attach it firmly. .

The reflector 3 has a back surface shape adapted to the locking wing 21 of the holding body 2, is slid and locked from the upper part of the column body 1, is in contact with the upper edge of the uppermost reflector 3, and is attached to the column body 1. A cap 4 is attached to the upper end, a stopper 5 is fixed in contact with the lower edge of the lowermost reflector 3, and the reflector 3 is sandwiched and held.
[0018]
The column main body is formed by extruding the rib and the concavo-convex groove. However, since the cross-sectional shape is simple and there is no undercut, the moldability is good and the yield is high. In addition, the holding body is easily attached so that even a complicated locking structure can be reliably provided. In addition, since the reflector is loosely fitted to the support body via the holder, the reflector can be easily replaced by removing the upper cap, and it is easy to separate and take out the material by type. The structure makes it easy to collect and recycle.
[0019]
Further, the support main body 1 and the holding body 2 are made of a thermoplastic synthetic resin, particularly polyethylene. When ultrasonic waves are applied, both resins are thermally fused to obtain strong adhesion, and the reflector 2 is locked. The locking wings 21 are provided with sufficient strength.
[0020]
The locking wings 21 are arranged along the concave and convex grooves 12 of the column main body 1, and the back surface of the reflector 3 is inserted between the ribs from the end of the column main body 1 in a shape that fits the locking wings 21. Since the reflector 3 can be locked over the entire length of the two planes of the column main body 1, a single plate or a plurality of plates are arbitrarily connected and inserted. In the reflector 3, the reflection portion 31 on the front surface and the locking portion 32 on the back surface are integrally formed of polycarbonate resin, but the reflection portion 31 and the locking portion 32 are formed of different materials and can be collected separately. It may be combined by a method.
[0021]
Further, the reflector 3 is locked by the locking wing 21 of the holding body 2, and a stopper 5 is provided in contact with the lower edge of the lowermost reflector 3. When the upper edge of the uppermost reflector 3 is in contact with the cap 4, the upper and lower deviations are restricted to narrow the reflector 3. The stopper 5 may be directly heat-sealed to the holding body 2 or the column body 1 or may be screwed with a screw or the like so that the reflector 3 does not shift downward. The cap 4 is screwed with a screw or the like in an appropriate structure, and the reflector 3 can be easily removed by removing the cap 4.
[0022]
In addition, the reflectors that are arranged on the upper and lower sides of the column main body are fixed to the holding body across the lower edge of the upper reflector and the upper edge of the lower reflector. The reflector is laterally regulated by the ribs of the column main body, and the vertical direction is narrowed by the cap and stopper, and the upper and lower parts of the reflector are locked by the retaining blades of the holder, and the column Since it is loosely fitted to the main body, when the column main body bends, it follows the bending and moves while the reflector is interposed, and is held without being damaged or deviated. Corresponding to such deformation, the holding body is heat-sealed across the part where the reflectors are provided continuously, and a gap for play is provided between the reflectors provided continuously. Therefore, even if the gaze guidance mark set up by the present invention swings with a restoring force even if it receives a slight impact or contact, it does not cause damage to the vehicle or person without causing damage to the main body.
[0023]
In addition, the column main body 1 has a hollow cylindrical shape, and a conductive protruding side 13 through which the steel pipe 6 can be inserted is provided on the cylindrical inner wall, so that the steel pipe 6 and the column main body 1 are integrated to increase the support force. Has been. Moreover, the cross-sectional shape of the hollow cylindrical column main body 1 is not necessarily rectangular, and the surface without the ribs 11 may be, for example, a convex curved surface or may be decorated. On the other hand, the rib 11 provided in the flat portion is fixed in position when the reflector 3 is locked, and the side surface is shielded so as not to be removed by mischief, and the support column has rigidity with the uneven groove in the center of the flat surface. It is

On the other hand, FIG. 4 and FIG. 5 are line-of-sight guide marks showing another embodiment of the present invention. A stopper 5 is fixed to the column 1, and a pair of holding bodies 2 along the outer surface of the column 1. Is fitted to the support column so as to be freely inserted into the support column, and the reflector 3 is fitted to the back surface of the holding body 2. A plurality of such reflectors are provided along a support column, and a holding body with a reflector is sandwiched between a cap 4 and a stopper 5 at the upper end of the support column body 1. The strut 1 may be a steel pipe, but a thermoplastic synthetic resin, particularly polyethylene, is preferably used in consideration of flexibility and bending and restoration even when external pressure is applied.
[0025]
The holding body 2 is divided into two parts and is integrally fitted with the concave and convex portions at the fitting portion 22, and the reflector 3 is attached to the back surface of the holding body 2, but is attached only to one side as necessary. May be made like that. In addition, in order to prevent rotation of the holding body 2, the upper and lower ends of the holding body, the cap and the stopper are provided with engaging portions 23, and are engaged with each other, and are engaged with the engaging portion 51 of the cap and the stopper.

【The invention's effect】
In the present invention, at least the support body and the holding body are formed of the same kind of thermoplastic synthetic resin, but the support body has a simple cross-sectional shape to improve productivity and product efficiency, and the support body exceeds the support body. It is structured to create a complicated locking structure by simply heat-sealing with sound waves. Therefore, it can be advantageously developed in terms of productivity, secondary workability, quality, and cost. Further, since the reflector is not tightly fixed to the column main body but is loosely fitted through the holding body and is narrowly provided, even if the column main body is bent, the reflector follows it and moves without difficulty. Therefore, even if a vehicle or a pedestrian comes in contact, the column main body bends and absorbs and restores the shock, so that the column is maintained without being damaged or the reflector not falling off. Even if the reflector is damaged, it can be easily replaced by removing the cap.
[0027]
Moreover, since the column main body is cylindrical and has the same cross-sectional shape, an arbitrary number of reflectors can be appropriately locked via the holding body. Therefore, it is possible to have a wide variation with a minimum number of members corresponding to traffic conditions and road surface conditions. In recent years, while recycling has been sought, the present invention can be made by heat fusion using the same resin, integrally formed, and by removing the cap, it is possible to easily collect and collect different types of resin reflectors. , The effective use of resources can be achieved. On the other hand, when the support strength is required depending on the installation location, the steel pipe can be inserted into the hollow inside of the column main body, so that it is possible to cope with the situation.
