Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a color cone in which a lighting device can be disposed for marking the outer area of obstacles occurring on a road.

<Prior Art> In order to make it easier for drivers of approaching cars to recognize road construction sites and obstacles on the road from a distance, a large number of safety cones are placed in a line outside the area. However, as shown in Japanese Utility Model Publication No. 54-33313, conventional cones of this kind are made of red synthetic resin and hollow cones arranged on a rectangular platform with an open bottom end. It has a structure in which a lighting fixture support boss is formed on the inner surface of the upper wall.

[Problem to be solved] However, in the color cone with the above-mentioned structure, the lower surface of the base plate is the grounding part all around, so there is There was a problem that the safety of the color cone deteriorated because the base part was placed on it.

《Means for solving the problem》 The present invention provides a collar cone that can be maintained in a stable posture even when using a power supply line.
To this end, a pair of lighting fixture support bosses are provided that protrude from the inner surface of the upper wall of the base plate, and reinforcing ribs are provided that protrude downward from the inner surface of the upper wall of the base plate outside the support bosses. It is characterized in that the four corners of the base plate are formed into ground legs by providing electric wire insertion holes in the ribs and cutting out the intermediate portions of the lower edges of the four circumferential side walls of the base plate.

<Operation> In the present invention, electric wire insertion holes are formed through the reinforcing ribs formed downward from the inner surface of the upper wall of the base plate, and the middle part of the lower edge of the four peripheral side walls of the base plate is cut out. The four corners of the board are formed into ground legs, so when a power supply line is inserted into the wire insertion hole, the fitted power supply line acts as a weight on the color cone, and the base board straddles the power line. This prevents the base plate from riding on the power supply line and jeopardizing stability.

<<Example>> FIG. 1 is a vertical side view, and FIG. 2 is a bottom perspective view.

This color cone is integrally formed of synthetic resin colored in a warning color such as red, and consists of a hollow cone part 1 and a rectangular base part 2.

The base portion 2 is formed with an open bottom surface, and a hollow cone portion 1 is continuously extended upward from the upper wall 3. A pair of support bosses 5 for supporting the lighting fixture 4 are formed on the inner surface of the upper wall 3 of the base plate section 2.
This support boss 5 is arranged on a line connecting the longitudinal center portions of opposing side wall portions 6 of the base plate portion 2.

Further, a support boss 5 on the inner surface of the upper wall of the base plate portion 2 is provided.
An annular reinforcing rib 7 extends downward from the outer side of the reinforcing rib 7, and the protruding height of the reinforcing rib 7 is such that its lower edge 8 is located higher than the ground surface and does not touch the ground. . A wire insertion hole 9 is transparently provided in the wall surface of the reinforcing rib 7 located on a line perpendicular to a line connecting the support bosses 5.
is a vertically oriented slit groove 10 that opens at the lower edge of the reinforcing rib 7.

The lower edges 11 of the four side walls 6 of the base plate part 2 are cut off leaving a little connecting part at both ends, and ground legs 12 are formed at the four corners of the base plate part 2. The cut height of this cut portion is such that it can straddle the power supply line to the lighting fixture 4.

In the color cone configured as described above, when a power supply line is fitted into the wire insertion hole 9, the fitted power supply line acts as a weight on the color cone, and the base part 2 is placed in a state where it straddles the power supply line. Therefore, the base plate part 2 will not ride on the power supply line and lose stability.

[Effects] In the color cone of the present invention, the lower edges of the four circumferential side walls of the base plate, which is formed into a substantially rectangular shape, are cut off leaving only the areas near both ends of each side wall, and ground legs are formed at the four corners. Therefore, since the power supply line of the lighting device passes through the cut-out portion, there is no possibility that the base plate part will ride on the power supply line. This prevents the color cone from being supported unstablely.

In addition, since the reinforcing ribs protrude downward from the inner surface of the upper wall of the base plate, the weight of the base plate increases, so the center of gravity of the collar cone is sufficiently low, and the reinforcing ribs are connected to the electric wires. Since the insertion hole is transparent, by fitting the power supply line into the wire insertion hole, the weight of the power supply line can be added to the cone, and stability can be further increased.
