Description

  The present invention is intended to provide a sign for a road safety, which has a very high guidance effect on the driver of the vehicle and has little resistance and damage even when a person or vehicle comes into contact.

  Traditionally, traffic safety signs on the outside of the road have been installed in places that are easily accessible to the driver's line of sight. Widely used on expressways, general roads, parking lots, etc.

  Even from the above situation, a high-performance reflective material that directionally reflects using a vehicle headlight is attached to a small sign that is used for traffic safety, making it easy for the driver to see. However, the number of elderly drivers is increasing in recent years, and it is necessary to install universal design signs that are friendly to such drivers.

  Patent Document 1 includes a diffusing lens having a diamond-cut surface on the back surface of the curved surface portion of the elastic base having a substantially fan-shaped cross section having a hollow inside and an arc-shaped curved surface on the outer wall. There is a description of a reflector for road, which is provided with a light reflecting member.

  In Patent Document 2, it can be easily installed at the time of curb block installation work, and it has excellent durability and visibility, and does not interfere with retroreflection even if there is a small amount of dust or snow, and for snow removal work. To provide mobile gaze guidance and its facilities that will not cause any problems. A reflector is attached to one side of a substrate made of an elastic body to form a reflection portion, and a rotation axis is formed on the other side of the substrate in a direction perpendicular to the substrate, and the rotation axis is A movable line-of-sight guide mark that is supported by the support portion and is capable of rotating the substrate is sandwiched between curb blocks in which a plurality of curb blocks are arranged, and the reflection part of the substrate protruding from the curb block is attached to the curb stone. There is a description that it is erected on the upper surface of the block or is tiltable on the side surface.

In Patent Literature 3, the road dividing line and the parking width line of the parking lot are covered with snow and cannot be seen due to snow or heavy fog. Therefore, even if snow is piled up, the three-dimensional board FIG. 1 is arranged into a three-dimensional board line so that the line does not disappear. When the plate of symbol 2 in FIG. 1 is stepped on, it is tilted to prevent slipping as symbol 2 in FIG. The board of symbol 2 in FIG. 1 absorbs solar heat and melts the snow on and around the surface of the solid board of symbol 1 in the drawing. And then, a material with elasticity and resilience is processed into the solid board shown in FIG. a.

  The problem to be solved is that various signs used for road safety are installed in consideration of the driver's line of sight, and the installation location is necessary for the vehicle to pass safely on the road. It is required to be installed at a place and have a high visual effect regardless of day or night.

  In the configuration of Patent Document 1, a base that is a pedestal is a molded product having a hollow space. Then, a diamond-cut molded product is inserted as a reflective material into the groove of the molded product. However, in this situation, the marking part cannot be enlarged or changed in shape according to the situation of the installation place, and there is nothing to reflect on the back side of the molded product having a hollow space, so the place to be used is Limited.

  With the configuration of Patent Document 2, even if a curb can be installed, it cannot be installed on an existing curb, and the direction of the reflector when it is installed cannot be changed. This is inconvenient because there is a situation where the headlight light is not reflected at an angle at which the light of the headlight is reflected, even if the direction of is limited.

  In the configuration of Patent Document 3, there is a difference between what is used by being affixed to the road surface and what is used as a sign, and it is meaningful to indicate only a plate-like protrusion and an arrow-shaped direction. There is a difference from what is marked. The fixed part stands upright and is constructed at an angle, and it is used only for marking during snowfall in a snowy country, and is severely damaged.

  In addition, tall plastic poles have a visual recognition effect on the driver, intimidation and flexibility, and are effective for traffic safety as such, but these poles are installed on narrow roads In such a case, the driving of the vehicle becomes extremely tight. Therefore, unstable driving is forced, which causes a traffic accident.

  Is it possible to supply a sign that is durable, easy to construct, and can be provided at a low price while maximizing the traffic safety effect with careful consideration for a long time in the road environment as described above? Was studied.

  In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that the arrow-shaped plate-like reflective sign with the lower end attached to the pedestal and the sign are integrally fixed so as to be inclined when viewed from the side. It is to provide a sign with an arrow.

  Hold the plate with the reflective material on the flat part of the cross section of the fixing base made of metal or plastics, or the concave or convex part, and fix it with a click rivet or screw. Thus, the three-dimensional arrow-shaped sign was invented by being attached to the fixing base so as to be substantially oblique, and integrated with the sign.

  By separately configuring the fixing pedestal and the plate-like reflection indicator, the size and shape of the pedestal and the plate-like reflection indicator can be changed separately. In particular, the reflective reflector can be applied with a reflective material in the form of a plate, or can be cut out or punched after being applied in a large format. Therefore, it is possible to easily cope with multipurpose requirements with minimum investment.

    The invention of claim 2 is to provide a three-dimensional arrow-shaped sign characterized in that the arrow-shaped marking portion of the three-dimensional arrow-shaped sign of claim 1 is bent into a cylindrical shape, and both end faces thereof are fixed to a pedestal. is there.

  The reason for curving the plate-shaped reflection sign in a cylindrical shape is to prevent the higher plate-shaped reflection sign that is constructed obliquely on the fixing base from being deformed back and forth or left and right, and in the unlikely event that a pedestrian There is no risk of injury if the contact part is cylindrical even if it comes into contact.

  The invention of claim 3 is that the marking portion of the solid arrow-shaped sign is folded into a mountain shape, the arrow shape is marked on both side surfaces of the mountain shape, and both end surfaces are separately attached to the pedestal so that the sign is fixed integrally. The object is to provide a featured solid arrow-shaped sign.

  Folding the marking part into a chevron, marking the arrow with the shape of "<" on both sides, and fixing both end faces to the pedestal improves the independence. Since it is bent in a mountain shape, it is a gentle design for pedestrians and a gentle design for vehicles and bicycles.

  Bending the plate-shaped reflection sign object into a mountain shape and fixing both lower end surfaces thereof to the fixing pedestal allows the distance between the lower ends of the fixed portions to be increased, so the plate-shaped reflection indicating object configured on the fixing pedestal is Even if the height of the mountain is increased from 100 mm to 300 mm, the independence is greatly improved. Since the internal space is thus large, it can be processed in the internal space when it is fixed to a sign or the like with a rivet, so that it looks good and is not easily tampered with. Further, the Yamagata may be formed by plastics vacuum forming, or may be made of metal such as aluminum.

  Most of the conventional traffic safety products are configured with a reflective material on the sign board, or directly attached to a structure such as a guard rail, a guard pipe, and a curb.

  On the other hand, in the three-dimensional arrow-shaped sign of the present invention, the plate-like reflective sign is made of plastics or rubber, and a light-reflective reflective material is attached or attached to the plate-like reflective sign. Alternatively, a solid arrow-shaped sign was invented by fixing a plate-shaped reflective sign obliquely to a sign or a road structure on a fixing base made of plastic or a combination of metal and plastic.

  Various structures, such as signs for adding guardrails, guardrail rails or pipes of guardpipes themselves, can be fixed by attaching a plurality of arrow-shaped reflection indicators to rail-shaped plates, or at curved points. It is attached as an arrow-shaped sign indicating the traveling direction of the vehicle, or as a sign that clearly indicates the presence of a curved mirror or prompts confirmation.

  Because the sign has a three-dimensional arrow shape, it stands out well, and even if it comes in contact with the vehicle frequently, it can be expected to have considerable restoring force from its shape, it can be easily replaced, and it seems to be less damaged It is in a small sign.

  In addition to the three-dimensional projection of the plate-like reflection sign from the structure or sign, the color of the reflective material can be mixed with a single color or multiple colors using red, yellow, blue or fluorescent colors. It is easy to stand out in the daytime and can be easily seen from the vehicle at sunset and at night by reflection with a retroreflective material, as well as bicycles, pedestrians, especially elderly people with weak traffic However, it was devised so that the three-dimensional arrow shape has a high guidance effect and can exhibit a traffic safety effect.

  In order to make the road look wide and comfortable, the height from the sign surface was decided to be about 300 mm or less. In addition, the three-dimensional arrow-shaped sign is attached in a plate shape or a cylindrical shape or a mountain shape by processing a plate material, so that it is less likely to be damaged even when touched by a vehicle.

  Manufactured with highly elastic and flexible thermoplastic elastomer, rubber, polyolefin resin, polycarbonate resin, the wall thickness is 0.3mm to 5mm, the size is 30mm to 300mm in height and width The shape and dimensions of the plate-shaped reflective sign and the fixing base are determined according to the installation location.

  If the wall thickness is 0.3 mm or less, there is a problem in independence and strength, and if it is 5 mm or more, it becomes too thick and becomes an obstacle, which causes a secondary disaster.

  Further, when the plate-shaped reflection sign is configured in a cylindrical shape, it may be configured in a cylindrical shape having various shapes including a round shape. At this time, the size of the plate-shaped reflection marking portion may be the same as the size from the front when the plate-shaped reflection marking portion is formed of a plate material.

  The material of the fixing base may be metal, plastics, or a combination thereof. In the case of metal, plated steel plate, stainless steel, and aluminum are used. In the case of adopting aluminum, in addition to the pressed aluminum plate material, the extruded shape material requires less investment depending on the shape, and the product unit price can be reduced.

  In order to fix the plate-shaped reflective sign to the sign, the back surface of the fixing base under the plate-shaped reflective sign is almost smooth, and the fixing base and the sign are bonded with adhesive, double-sided tape, or screws. Secure with rivets.

  It was decided to apply a reflective material to the surface of the plate-shaped sign. The light retroreflective material affixed to the surface of the plate-shaped sign object protrudes from the sign so that the light of the vehicle headlight hits diagonally at a curved point, etc. Since the reflective material is oriented to the angle at which it shines best, it reflects well and improves visibility, which is effective for traffic safety. In addition, since the plate-like reflection sign is three-dimensionally attached, it becomes conspicuous well day and night for weak traffic people such as pedestrians.

  In addition, it is important that these three-dimensional arrow-shaped signs stand out best from the vehicle, but it can vary from large trucks to small light vehicles. The headlights are different in height and the width of the road is different, so the incident angle and the viewing angle of the headlights are also different. The reflective sheet used for the three-dimensional arrow-shaped sign may be a diamond-cut type or a small glass bead as long as the incident angle and the viewing angle can be changed.

  Although it is a relatively small plate-like reflective sign, it stands out from the sign or protrudes from structures such as guardrails, so it is highly visible to the driver even during the daytime, and the headlights that face downward at night However, the light is well-lighted and the visibility is greatly improved, so the traffic safety effect is higher both day and night.

  As described above, the three-dimensional arrow-shaped sign of the present invention has a high visual effect despite being relatively small for vehicles and people. The visibility is good when the reflective sheet is used in red, yellow, green, blue, fluorescent colors, etc., and the color of the projection is the closest to the road. It is easy to see because it is installed in a structure.

  Therefore, the road alignment looks good and the vehicle can travel with peace of mind. At night, the headlight of the vehicle can be installed as much as possible in front of the front with good reflection efficiency, so it reflects very well and can guide the line of sight smoothly.

  Plate-shaped and arrow-shaped three-dimensional signs can be manufactured with molded products composed of elastic thermoplastic elastomer, rubber, polyolefin resin, polycarbonate resin, etc. Minimal. Furthermore, because it is composed of a plate shape, cylinder shape, or mountain shape, even if it comes in contact with the vehicle, the elasticity and shape of the material can absorb impact, friction, and pressure, and the degree to which the molded product will be permanently deformed. Less is needed.

  The pedestal for fixing is configured at the bottom of the plate-shaped reflective sign, but it is constructed obliquely at the rising cross-section of the plate-shaped reflective sign so that the pedestal and the plate-shaped reflective sign are integrated. As a result, a three-dimensional sign can be manufactured at low cost. Further, there is no problem even if the plate-like end portion is bent to substitute the fixing base.

  In particular, when mounted on a curved sign, the reflective material conventionally formed on the sign plate changes the headlight direction, the incident angle on the sign changes as the vehicle approaches, and the sign no longer reflects. Cannot be seen, and gaze guidance cannot be performed.

  Also, when this plate-like reflective sign is configured on a sign of the type attached to the guardrail, if a reflective sheet is also formed on the back of this three-dimensional sign, the road alignment can be seen well from the vehicle in the opposite lane. It is convenient because it stands out well for pedestrians and bicycles.

  Although it is a sign with a small three-dimensional arrow, this three-dimensional arrow guides the vehicle because it stands up diagonally from the sign board surface or protrudes from a structure such as a guardrail, and it has a visual effect from the driver even in the daytime. At night, the headlights that shine downwards shine well, and the visibility is greatly improved, so that the road safety effect is higher both day and night.

  In particular, it can be said to be plate-shaped and easily sways in the wind. In addition to vehicles, bicycles, pedestrians, especially elderly people, and other traffic weak people have a high gaze guidance effect, and the effect is tremendous.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a plate-like reflective sign 2 (A) that is the center of the configuration of the solid arrow-shaped sign of the present invention. The height of the plate-like reflection object 2 (A) is 100 mm, the width is 100 mm, the base 3 is made of aluminum, the wall thickness is 1.5 mm, the bottom width is 25 mm, and the length is 100 mm. The reflective material 4 is pasted on the plate material. The plate material and the pedestal 3 are configured so that the plate material is inclined at 45 degrees with respect to the pedestal 3 in cross section. This oblique angle does not have to be 45 degrees, and may be freely configured to some extent depending on the installation location and the product. By slanting, there is little resistance to the driver, and even if it touches the car, it is hard to be damaged.

  The plate-shaped reflection sign 2 (A) is a pedestal that is obtained by pasting a reflection sheet on the surface and / or the back surface of a 0.5 mm polycarbonate resin plate and caulking at the lower end portion of the concavo-convex portion 5 of the cross section of the pedestal 3 3 is attached obliquely and integrated. In addition to caulking, it may be fixed with screws or an adhesive.

  FIG. 2 is a perspective view in which the plate-like reflection sign 2 (B) is formed into a cylindrical shape. A reflective material 4 with an arrow-shaped mark is affixed to the plate-like reflection sign 2 (B). The reflective material 4 having excellent light reflexivity used here may be a reflective material using a glass bead having a very small and high refractive index, or a reflective sheet having a diamond cut on a thin plastic sheet. It may be. Although a reflective sheet is affixed to the part which becomes the surface and back surface of the plate-shaped reflective sign 2 (B), it is convenient to affix it when it is a flat plate material before assembling.

  FIG. 3 is a perspective view of the three-dimensional arrow-shaped sign 1 (A) in which three plate-like reflective signs 2 (A) are attached to the side surface of a 500 mm long guardrail attached sign that is attached so as to cover the guardrail. is there. This guardrail mounting sign has traditionally been used as a warning sign by sticking a reflective material in a striped pattern on the surface, but the reflection performance of the headlight light from the side of the guardrail is naturally poor, so a corrugated reflective sheet is attached. It has been devised to reflect the light from the side by attaching the member in the center or by attaching a three-dimensional reflector by diamond-cut injection molding.

  However, these are only signs that reflect a little linearly on the side of the guardrail, and the visibility is only one. In the present invention, as shown in FIG. 3, the arrow is projected and attached in a three-dimensional manner, it becomes a sign that is very effective for clearly indicating the direction of road alignment and the presence of guardrails.

  FIG. 4 is a three-dimensional arrow-shaped marker 1 in which six plate-like reflective indicators 2 (A) are attached to the side surface of a strip-shaped molded article rail (A) 6 made of an extruded aluminum material at a 45-degree angle. (B). The pedestal 3 is fixed to the molded product with a click rivet. When there is a possibility that a vehicle, a person, a bicycle, or the like may come into contact with the side surface of the solid arrow-shaped sign 1 (B), a plate-like reflective sign having a cylindrical shape as shown in FIG. 2 may be attached.

  If the groove 11 is formed in the cross section of the rail (A) 6 made of the extruded aluminum material, the strength of the rail (A) 6 is increased, and the mounting screw in the groove 11 is also attached to the structure. Because it fits in the head, it becomes a beautiful sign.

  FIG. 5 is a cross-sectional view in which the plate-like reflective indicator 2 (A) is changed to the plate-like reflective indicator 2 (B) with the solid arrow-shaped marker 1 (B) in FIG. The arrow shape of the plate-like reflection marking object 2 (B) protrudes from the side surface 10 of the guardrail and can be visually recognized, and this arrow shape has high visibility for guiding the traveling direction of the vehicle.

  FIG. 6 is a perspective view in which the solid arrow-shaped sign 1 (B) of FIG. 4 is attached to a retaining wall 13 such as an elevated road. In this figure, the plate-like reflection indicator 2 (A) of FIG. 1 is attached, but the plate-like reflection indicator 2 (B) may be used. It attaches to a concrete retaining wall with a screw, a bolt, etc. using the recessed part of the groove | channel 11 of a rail (B) 7.

  FIG. 7 is a cross-sectional view of the solid arrow-shaped sign 1 (C) attached by the band metal fitting 16 so as to be held from the outside to the side surface of the beam 9 of the guard pipe. If the rail (B) 7 has a C-shaped groove for inserting bolts or nuts at the top and bottom of its cross-section, it can be easily mounted with a hat-shaped band bracket 16 that is usually used when mounting to the beam. I can do it. Also at this time, the plate-like reflective indicator 2 (A) protrudes from the side surface of the beam 9 and can be visually recognized, and the arrow indicates the direction of travel of the vehicle, so that the visibility is high.

  FIG. 8 is an invention for making it easier to see a sign having an arrow shape of “<”. This arrow is also a sign that expresses the traveling direction of the road such as a curve, and is usually used with a reflective sheet pasted on the plane of the sign board, but the direction of the headlight of the car changes every moment at the curve point In many cases, it is difficult to determine which direction the sign should be directed, especially on sharp curves, because the direction of the sign from one direction cannot be processed. Had been installed on.

  FIG. 8 is a perspective view of a three-dimensional arrow-shaped marker 1 (D) in which two surfaces are formed by projecting the surface of the marker into a chevron, and the U-shaped reflecting material 4 is marked on each of the two surfaces. The pedestals 3 of both ends of the chevron-shaped chevron plate-shaped reflection marking object 15 are fixed to the aluminum plate material. The material constituting the chevron may be made of resin such as polycarbonate, or may be made of metal such as an aluminum plate. Further, the reflecting material at this time may be a reflecting sheet or a molded product of a reflecting prism. By using the solid arrow-shaped sign 1 (D) having such a configuration, the sign serves as two signs for vehicles coming from both the left and right sides of the curve point. Become.

  FIG. 9 is a perspective view of the solid arrow-shaped sign 1 (E) attached to the column of the curve mirror 12. Curved mirrors that are usually mounted at a position of about 3 meters above the ground are sometimes mounted at high places, making it difficult to visually recognize their presence and mirror surface. And urged visual recognition.

  However, for the vehicle from the side of the curve mirror 12, the caution sign is not visible. Therefore, as shown in FIG. 9, the plate-shaped reflective sign 2 </ b> A or 2 </ b> B is formed on the front surface of the curved mirror with the three-dimensional arrow-shaped label 1 (E) facing the mirror surface. The presence and confirmation of the curved mirror 12 is configured in an easily visible form with an arrow.

  We have described the utility of the sign with a three-dimensional arrow, but due to changes in the times, there are various structures and brightness around the road. Although it has been developed and used, it is also close to the limit, and there is a need for maintenance-free signs based on new ideas.

  Self-luminous products using light-emitting diodes and batteries, such as products using LEDs, are also excellent because they have excellent visibility, but they are expensive, and after 5 years, the performance of LEDs will drop and the life of the battery will also be shortened. run out. Considering such a thing, I think that the present invention which is inexpensive and requires almost no maintenance is really necessary.
