Description

[Technical field]

[0001] The present invention relates to a safety sign cone which is widely used as a road safety sign, an advertisement sign, a guide sign, etc. [Background technology]

[0002] Conventionally, generally cone-shaped safety sign cones made of plastic or the like have been used to indicate the limits of road widths such as roadways at road construction sites, or to guide vehicles at various event venues. The specific configuration of such safety sign cones is that a base plate that is substantially rectangular in plan view and has an outward flange shape is provided at the lower end of the cone-shaped main body, and this base plate allows the cone to be stably held upright.

[0003] Such safety cones are usually used outdoors, and the main body of the cone is made thin to reduce the overall weight, while the main body of the cone is made thick enough (diameter) to increase visibility, so that the wind resistance area is large. Therefore, if a safety cone is simply placed on the ground, it may move or fall over in strong winds.

[0004] To prevent the device from falling over, a cone bed (weight) weighing about 2 kg is sometimes used. Such a cone bed is generally made of hard rubber, and is ring-shaped or has a rectangular flat surface with a circular through hole in the center, and is configured so that the main body of the cone is inserted into the hole to press down on the base plate.

[0005] However, when using such a cone bed, it is necessary to quickly cover the safety sign cone with the cone bed after installing it, and if the safety sign cone falls over due to contact with a vehicle or the like, the cone bed may come off. Furthermore, since the cone bed itself is heavy, the installation and retrieval work is difficult, which presents problems.

[0006] For this reason, for example, in the following Patent Documents 1 and 2, multiple holes are drilled in the cone body and wind is allowed to pass through the holes to reduce wind pressure and prevent the cone from falling over. Also, in the following Patent Document 3, a vertically long hole is formed on the underside of the cone body, making the inside of the cone body visible from the outside, making it easy to check for the presence of suspicious objects.

[0007] [Patent Document 1] Japanese Utility Model Application Publication No. 64-045882 [Patent Document 2] Japanese Utility Model Application Publication No. 55-123017 [Patent Document 3] JP 2006-146105 A Summary of the Invention [Problem to be solved by the invention]

[0008] Incidentally, the above-mentioned safety sign cone is made of a relatively flexible thermoplastic resin such as polyvinyl chloride (PVC) so that it is not easily broken by the impact when a vehicle or a person hits it. Therefore, if a large number of holes are drilled in the main body of the cone as in the above-mentioned Patent Documents 1 to 3, the strength is significantly reduced, and it is easily broken by the impact when a person or a vehicle hits it. Furthermore, if it is installed in a place where the ground surface temperature reaches 50°C, such as asphalt or concrete in summer, the cone will soften due to the heat and lose its shape, causing a serious problem that it cannot perform its function. In addition to wind pressure, it may be washed away by the water flow when roads are flooded.

[0009] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a novel safety sign cone that exhibits excellent wind and water pressure resistance and can maintain its shape without being distorted by impact, heat, etc. [Means for solving the problem]

[0010] In order to solve the above problems, the first invention is a safety sign cone having a cone-shaped cone body made of thermoplastic resin, characterized in that the cone body has a plurality of vertically elongated elliptical holes formed in the circumferential direction and in the vertical direction. With this configuration, the cone can maintain its shape without losing its shape due to heat, impact, etc. while exhibiting excellent wind and water pressure resistance performance.

[0011] The second invention is a safety sign cone according to the first invention, characterized in that the cone body is divided into three regions in the height direction, a plurality of holes are formed in the upper region of the cone body along the circumferential direction, a plurality of holes are formed in the middle region of the cone body so as to be offset from each hole in the upper region, and a plurality of holes are formed in the lower region of the cone body so as to be offset from each hole in the middle region.

[0012] With this configuration, the holes in the upper region of the cone body allow wind to pass through, preventing the cone body from tipping over due to wind pressure. Also, the holes in the middle region of the cone body allow wind to pass through, preventing the cone body from tipping over and allowing the inside of the cone body to be easily viewed from the outside through the holes.

[0013] Furthermore, the holes in the lower region of the cone body not only allow the inside of the cone body to be easily seen from the outside through the holes, but also prevent the cone body from being swept away by water when the road on which it is installed is flooded, as water passes through the holes in the lower region and passes through the inside and outside of the cone body. Furthermore, the holes in each region are offset from each other at the top and bottom, so that the load is not concentrated in one area and the strength of the cone body can be maintained. This allows the cone body to maintain its shape without losing its shape even when subjected to impact or heat.

[0014] The third invention is a safety sign cone according to the first or second invention, characterized in that the holes are formed in pairs at each height on either side of the central axis of the cone body. With this configuration, wind and water flowing into the cone body from one hole flows straight out to the other hole, reducing wind and water pressure on the cone body. This increases resistance to wind and water pressure and prevents the cone body from falling over or being swept away.

[0015] The fourth invention is the safety sign cone according to the first or second invention, characterized in that the height of the cone body is 600 mm or more, and each of the oblong holes has a major axis of 70 to 100 mm and a minor axis of 45 to 60 mm. With this configuration, the load is not concentrated in one area, and the strength of the cone body can be maintained, so that the shape can be maintained without losing its shape even when subjected to impact or heat.

[0016] The fifth invention is a safety sign cone according to the first or second invention, characterized in that the cone body is made of polyvinyl chloride (PVC) or polyethylene (PE). Among thermoplastic resins, polyvinyl chloride (PVC) and polyethylene (PE) are excellent in processability, weather resistance, impact resistance, etc., and have traditionally been widely used as materials for safety sign cones used outdoors. Even when polyvinyl chloride (PVC) or polyethylene (PE) is used, the safety sign cone of the present invention can achieve the above-mentioned effects.

[0017] The sixth invention is a safety sign cone according to the first or second invention, characterized in that a rubber base plate is provided at the bottom of the cone body. By providing such a rubber base plate, the cone body can be stably held against the impact force when a person or vehicle hits it, as well as against continuous forces due to wind pressure and water pressure. Effect of the Invention

[0018] The safety sign cone of the present invention has a conical cone body with multiple elongated elliptical openings formed in the circumferential and vertical directions, which not only allows it to remain stable even when subjected to wind pressure or water pressure, but also provides excellent internal visibility and allows it to firmly maintain its shape even when subjected to impact or heat, without easily losing its shape.

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Figures 1 to 4 show one embodiment of a safety sign cone 100 according to the present invention. As shown in the figures, the safety sign cone 100 is mainly composed of a cone-shaped cone body 10 and a base 20 connected to the bottom of the cone body 10.

[0021] The cone body 10 is made of a thermoplastic resin such as polyvinyl chloride (PVC) or polyethylene (PE), and although its size is not particularly limited, it is, for example, as shown in Fig. 2, a hollow elongated cone shape with a height of 600 to 1000 mm or more (700 mm in the illustrated example), a bottom diameter of 300 to 400 mm (345 mm in the illustrated example), and a top diameter of 50 to 100 mm (80 mm in the illustrated example). The plate thickness of this cone body 10 is, for example, about 2 to 5 mm, but is not limited to this. In addition, the cone body is colored in a conspicuous color such as red, green, or yellow.

[0022] The cone body 10 has a plurality of vertically elongated elliptical holes 11-13 formed (drilled) in the circumferential and vertical directions. More specifically, as shown in Fig. 2, the cone body 10 is divided into three regions Z1-Z3 in the height direction, and the upper region Z1 has four holes 11, 11, 11, 11 formed at equal intervals along the circumferential direction as shown in Fig. 3 and Fig. 4. Similarly, the middle region Z2 has four holes 12, 12, 12, 12 formed at equal intervals along the circumferential direction, but the opening positions of the holes 12, 12, 12, 12 are offset from the four holes 11, 11, 11, 11 in the upper region Z1, that is, the holes 12, 12, 12, 12 are drilled so that they are located between the holes 11, 11, 11, 11 when viewed from above as shown in Fig. 3.

[0023] Further, in the lower region Z3 below, four holes 13, 13, 13, 13 are formed at equal intervals along the circumferential direction, but the opening positions of the holes 13, 13, 13, 13 are offset from the four holes 12, 12, 12, 12 in the middle region Z2, that is, the four holes 13, 13, 13, 13 are drilled so as to be positioned between the holes 12, 12, 12, 12 when viewed from above as shown in Fig. 3. And, the holes 11, 11, 11, 11, 12, 12, 12, 12, 13, 13, 13, 13 are formed so as to be paired with each other on either side of the central axis of the cone body 10 at each height as shown in Figs. 2 and 3.

[0024] As shown in Figures 5, 6 and 9, a flange 14 is formed at the lower edge of the cone body 10 and extends radially outward, and multiple (several tens of) cylindrical or elliptical cylindrical protrusions 15, each of which is several millimeters high, are formed along the circumferential direction on the upper and lower surfaces of the flange 14.

[0025] On the other hand, the base 20 is a rectangular plate material (365 mm x 365 mm) that is integrally joined to the bottom of the cone body 10, and is made of a material that is elastic, such as natural rubber or synthetic rubber, and has a higher specific gravity than thermoplastic resins such as polyvinyl chloride (PVC). As shown in Figures 7 and 8, an opening 21 for fitting the cone body 10 is formed in the center of the base 20, and the flange 14 of the cone body 10 is attached to the edge of this opening 21.

[0026] That is, as shown in Fig. 8, a plurality of fitting holes 22 are drilled along the circumferential direction at the edge of the opening 21 of the base 20, and as shown in Fig. 10, slits 23 are formed so as to extend in the circumferential direction at the edge of the opening 21. Then, as shown in Fig. 11, the flange 14 of the cone body 10 is fitted into the slits 23, and each protrusion 15 on the flange 14 is fitted into each fitting hole 22 on the base 20 side, and then these are heat-welded to integrate the cone body 10 and the base 20.

[0027] The safety sign cone 100 of the present invention having such a configuration, when installed on a road or floor surface GL as shown in Fig. 12, notifies the surroundings of its presence and can exert various effects. That is, first, the holes 11, 11, 11 in the upper region Z1 of the cone body 10 allow wind to pass through, thereby preventing the cone body 10 from falling over due to wind pressure. In addition, the holes 12, 12, 12, 12 in the middle region Z2 of the cone body 10 also allow wind to pass through, thereby preventing the cone body 10 from falling over, and the inside of the cone body can be easily seen from the outside through the holes 12, 12, 12, 12. Therefore, if a suspicious object is placed inside the cone body 10, it can be easily found from the outside.

[0028] Furthermore, the holes 13, 13, 13, 13 in the lower region Z3 of the cone body 10 not only make it easy to see inside the cone body 10 from the outside through the holes 13, 13, 13, 13, but also, if the road on which this is installed is flooded, water will pass through the holes 13, 13, 13, 13 in the lower region Z3 and flow through the inside and outside of the cone body 10, preventing the cone body 10 from being swept away by water pressure.

[0029] In addition, since the holes 11, 11, 11, 11, 12, 12, 12, 12, 13, 13, 13, 13 are formed in pairs at each height on either side of the central axis of the cone body 10, wind and water that flow into the cone body 10 from one hole flows straight out to the other hole, reducing wind and water pressure on the cone body 10. This increases resistance to wind and water pressure and prevents the cone body 10 from falling over or being swept away.

[0030] And because the holes 11-13 in each of the regions Z1-Z3 are formed in an offset state above and below, the load is not concentrated in one area, and the strength of the cone body 10 can be maintained at a high level. This allows the shape to be maintained without losing its shape even when subjected to impact or heat. Furthermore, the rubber base 20 provided at the bottom of the cone body 10 allows it to resist the impact force when a person or vehicle hits it, as well as continuous forces due to wind pressure and water pressure, and therefore the cone body 10 can be held stably.

[0031] In this embodiment, as shown in Fig. 1, an opening 10a is provided at the top of the cone body 10, so that a sign or the like can be inserted and attached thereto, but the opening 10a may be omitted. Furthermore, by attaching reflective tape 16, 17 or the like to the cone body 10, visibility at night or from a long distance can be further improved. Also, although it depends on the material constituting the cone body 10 and the thickness of the cone body 10, when a thermoplastic resin such as polyvinyl chloride (PVC) is used, if the size or total area of ​​the holes 11 to 13 is made larger than this as shown in Figs. 1 and 2, the product will not be durable and will be difficult to maintain.
