Description

[Detailed description of the invention] The present invention relates to a safety cone indicator,
Safety cones, which are widely used especially at nighttime construction sites and traffic control areas, are equipped with a light-reflecting device made of transparent synthetic resin with many prism-shaped protrusions on the back. death,
When exposed to light from a car's headlights, etc., this marking device effectively reflects the light, clearly indicating the dangerous area to drivers, ensuring the safety of workers, passersby, and passing vehicles. It is for.

Safety cones are cone-shaped safety signs made of red synthetic resin, etc. Due to their material and shape, they are lightweight and durable, and can be stacked and carried, so they are widely used at construction sites and traffic control areas. ing. And for night use,
To improve visibility, a light bulb is generally installed inside the safety cone. However, the use of this light bulb caused problems not only in terms of electricity costs and the hassle of wiring, but also in terms of visibility. In other words, the light bulbs are illuminated from inside the safety cone through red synthetic resin, etc., so bicycles and pedestrians can easily be seen, but drivers of cars can't see them due to the lack of light when driving at high speeds. It was difficult to do so, and accidents such as contact with the safety cone were constant.

On the other hand, conventionally, an annular band 3 is arranged on the top of a safety cone 1' as shown in FIG. There were some devices that were fitted with lights to reflect light from automobile headlights, etc., to improve visibility at night. However, in this safety cone indicator using an annular band, the light reflecting block piece 2 made of transparent synthetic resin with many prism-shaped protrusions on the back side is not completely continuous, so the reflection may vary depending on the angle of the incident light. This results in a difference in direction, and when manufacturing, it requires a lot of effort to attach a plurality of light-reflecting block pieces 2 to the annular band 3, resulting in high costs and disadvantages. .

The present invention was made in view of the above-mentioned problems and provides a new safety cone indicator.The present invention is made of a transparent synthetic resin having a cylindrical shape on the upper part of the safety cone and a large number of prism-shaped protrusions on the back surface on the entire outer periphery. By installing a sign equipped with a light reflecting part made of a light reflecting part, etc., it reflects incident light from all directions equally and effectively, further improving visibility at night. Regarding manufacturing costs, it can be provided at a low price because it does not require the labor and effort of attaching a plurality of light-reflecting block pieces.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view of the main body 4 of the safety cone indicator, in which 5 is a mounting portion and 6 is a light reflecting portion. The main body 4 of the safety cone indicator generally consists of a mounting part 5 and a light reflecting part 6. Mounting part 5
is made of synthetic resin, etc., and the inner surface 5d of the mounting portion 5 is shaped like a truncated cone so as to be fitted onto the upper part of the safety cone, and as shown in FIG. A stopper recess 7 is provided around the entire circumference. By engaging this locking recess 7 with a locking protrusion 8 provided on the safety cone 1, the safety cone 1 is firmly fitted. Furthermore, it can also be fitted to a conventionally used safety cone 1' which does not have the locking convex portion 8. Here, the inside 5 of this mounting part 5
Of course, the locking recess 7 provided at d may be a convex portion, and the locking convex portion 8 provided on the safety cone 1 may be a recess. The outer surface 5c of the mounting portion 5 has a cylindrical shape, and its upper end 5a and lower end 5b are formed slightly larger. Then, this upper end 5a and lower end 5
c tightly wraps around the light reflecting section 6 attached in the middle thereof.

The light reflecting section 6 is made of transparent synthetic resin or the like, has a smooth surface 6c, and has a large number of prism-shaped protrusions 9 on the entire surface of its back surface 6d. FIG. 3 is a diagram showing a prism-shaped protrusion 9 formed on the back surface 6d of the light reflecting section 6. As shown in FIG. These prismatic protrusions 9
As a result, the light that perpendicularly enters the surface 6a of the light reflecting section 6 is totally reflected.

The light reflecting section 6 is attached so that the back surface 6d on which the prism-shaped protrusion 9 is formed is in contact with the outer surface 5c of the mounting section 5.

Further, the upper end 6a and the lower end 6b of the light reflecting section 6 are formed to be slightly larger, so that the light reflecting section 6 is attached in contact with the upper end 5a and the lower end 5b of the outer surface 5c of the attachment section 5.

As a result, the light reflecting part 6 is securely attached to the mounting part 5, and rainwater, dust, etc. can enter between the light reflecting part 6 and the mounting part 5, and the back surface of the light reflecting part 6
It is designed to prevent the light reflection ratio from decreasing due to adhesion to d.

Next, the operation of the embodiment according to the present invention will be explained.

When the safety cone indicator main body 4 according to the present invention is fitted as shown in Fig. 4 to a large number of safety cones 1 installed at nighttime construction sites and traffic control areas, the safety cone marking body 4 according to the present invention can be installed in large numbers at nighttime construction sites and traffic control areas. Prism-shaped protrusion 9 that is totally reflective when exposed to light
is formed on the entire circumference of the back surface 6d of the light reflecting portion 6,
Furthermore, since the surface 6c of the light reflecting section 6 is a vertical cylindrical surface, the generally horizontal incident light from automobile headlights, etc. can be reflected on the entire surface of the light reflecting section 6, providing an extremely advanced sign function. able to demonstrate.

Here, a light bulb or the like is provided inside the safety cone 1 to ensure visibility for bicycles and pedestrians who do not have effective irradiation light, and the safety cone marking body 4 according to the present invention is installed as a safety cone. If it is fitted onto the top of the cone 1, an even better sign can be obtained.

Next, in order to manufacture the safety cone marking main body 4 according to the present invention, the cylindrical mounting portion 5 and the rectangular plate-like light reflecting portion 6 are separately formed by die cutting, etc. The back surface 6d of the portion 6 is attached with adhesive or the like so as to be wrapped around the outer surface 5c of the attachment portion 5.

As described above, the safety cone marking device according to the present invention is easy to manufacture, so it can be provided at a low price. The entire surface has prism-shaped protrusions that effectively reflect light, making it highly visible. Furthermore, since it is only necessary to fit the main body of the indicator into the safety cone, installation work can be easily performed.Furthermore, it can also be fitted into the conventional safety cone, so if it gets dirty, By cleaning only the main body of the sign, it is possible to maintain extremely high level of sign function for many years.
