Description

The present invention relates to a triangular cone installed on a construction site on a road.

When the work vehicle is stopped on the road for construction work such as wiring of overhead cables, it is obliged to install a safety fence around the work vehicle in order to ensure the safety of the work. For the safety fence, for example, a triangular cone (also referred to as a safety cone, a pylon, or a color cone (registered trademark)) and a cone bar are used. The triangular cone is a conical shape with a pedestal. The cone bar is a rod of yellow and black tiger stripes (white and red stripes and fluorescent yellow and black stripes), and is provided with rings at both ends for attaching the cone bar to the tip of the triangular cone. When installing the safety fence, place triangular cones around the work vehicle at intervals of the length of the cone bar, and attach the cone bar to the tip of the triangular cone. To install a safety fence that surrounds the work vehicle, 4 to 6 cone bars are required. A cone bar tape attached to the tip of a triangular cone is also known as a substitute for the cone bar (for example, Non-Patent Document 1).

Here, a general installation of a security fence using a triangular cone and a cone bar will be described. After stopping the work vehicle at the construction site, take out the triangular cone. The triangular cones are stacked and placed on the work vehicle. After taking out the triangular cone, place the triangular cone around the work vehicle. When the work vehicle is parked on the road shoulder, triangular cones are placed in front of and behind the work vehicle and on the side of the work vehicle on the roadside. The side of the work vehicle cannot be covered with a single cone bar, so multiple triangular cones are placed. After placing the triangular cone, remove the cone bar from the work vehicle and attach it to the triangular cone.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiments described below, and changes may be made without departing from the spirit of the present invention.

FIG. 1 is a perspective view showing the configuration of the triangular cone 1 of this embodiment.

A triangular cone 1 shown in FIG. 1 includes a conical hollow main body 10, an outlet 11 provided at an upper portion of a side surface of the main body 10, and a base 12 provided around a bottom portion of the main body 10. Although not shown, the main body 10 has an installation portion for attaching the cone bar tape 20 therein. The main body 10 and the base 12 are molded of synthetic resin such as polyethylene. The height of the triangular cone 1 is 700 mm, and the base 12 is 385 mm square. The size of the triangular cone 1 is not limited to this, and may be any size suitable for the intended use.

The outlet 11 is a hole that is elongated in the vertical direction and penetrates the side surface of the main body 10. The upper end of the outlet 11 is located at a position where the ring does not interfere with the outlet 11 when the ring at the tip of the cone bar is fitted to the triangular cone 1. A plurality of outlets 11 may be provided.

The cone bar tape 20 is built in the hollow portion of the main body 10. As a mounting portion to which the cone bar tape 20 is attached, a commercially available cone bar tape 20 may be placed by providing a stand in the hollow portion, or a cone bar tape 20 may be wound by providing a shaft in the hollow portion. The cone bar tape 20 can be taken out from the take-out port 11. An example of a method of fixing the cone bar tape 20 will be described. The cone bar tape 20 is fixed to a circular base that serves as an installation portion, and the tip of the cone bar tape 20 is inserted from the opening of the base 12 and taken out from the outlet 11. The base on which the cone bar tape 20 is fixed is inserted from the opening of the base 12 and fixed to the main body 10. The bottom surface of the base and the inner wall of the main body 10 may be fixed with an L-shaped metal fitting. The size of the table is about the size of the inner circumference of the main body 10 below the outlet 11. A mainspring may be provided inside the main body 10 so that when the cone bar tape 20 is slightly pulled and then released, the cone bar tape 20 is wound.

The length of the cone bar tape 20 is about 5 m, which is about the entire length of a general work vehicle. The width of the cone bar tape 20 is about 5 cm. The length and width of the cone bar tape 20 are not limited to this, and may be any size suitable for the intended use. The cone bar tape 20 has a yellow and black tiger pattern (a white and red striped pattern or a fluorescent yellow and black striped pattern). The letters may be written on the cone bar tape 20. For the cone bar tape 20, a synthetic resin such as polyvinyl chloride can be used.

A string 21 for fixing the tip portion to another triangular cone is attached to the tip portion of the cone bar tape 20. The size of the loop of the string 21 is about the size of the ring at the tip of the commercially available cone bar. The triangular cone to which the string 21 is attached may be a commercially available triangular cone or the triangular cone 1 of this embodiment. When the cone bar tape 20 is stored inside the main body 10, the string 21 is exposed. By pulling the string 21, the cone bar tape 20 can be pulled out from the inside of the main body 10.

By making the string 21 flexible and freely deformable, the conventional triangular cone 50 can be overlaid on the triangular cone 1 as shown in FIG. Further, there is no obstruction when attaching a cone bed (weight) to the triangular cone 1.

Next, an example of use of the triangular cone 1 of this embodiment will be described.

FIG. 3 is a diagram for explaining a usage example of the triangular cone 1 of the present embodiment. In the usage example shown in FIG. 3, one triangular cone 1 of this embodiment, three conventional triangular cones 50A to 50C, two cone bars 60A and 60B, and two signboards 70A and 70B are used. ..

In FIG. 3, the triangular cone 1 of the present embodiment is arranged on the roadway side in front of the work vehicle 100 parked near the shoulder of the road, and the conventional triangular cone 50A is arranged on the sidewalk side in front of the work vehicle 100. ing. Further, conventional triangular cones 50B and 50C are arranged on the roadside and the sidewalk behind the work vehicle 100, respectively.

When the cone bar tape 20 is installed on the road side, the cone bar tape 20 is pulled out from the triangular cone 1 and attached to the triangular cone 50B arranged on the road side behind the work vehicle 100. Since the length of the cone bar tape 20 is longer than the entire length of the work vehicle 100, it is possible to reduce the number of triangular cones installed on the road side. Since the cone bar tape 20 is built in the triangular cone 1, it is sufficient to install the triangular cone 1 and then take out the cone bar tape 20 and attach it to the triangular cone 50B.

A cone bar 60A is attached between the triangular cone 50A and the triangular cone 1 arranged on the sidewalk side in front of the work vehicle 100. A cone bar 60B is attached between the triangular cones 50B and 50C arranged on the road side and the sidewalk behind the work vehicle 100. Signboards 70A and 70B are attached to the cone bars 60A and 60B.

As described above, by using the triangular cone 1 of the present embodiment, it is possible to reduce the number of cone bars to be used, and it becomes unnecessary to walk with many cone bars on a road having a large traffic volume.

Since the conventional triangular cones 50A to 50C can be stacked on the triangular cone 1, no space is required when the triangular cones 1 and 50A to 50C are mounted on the work vehicle 100.

Subsequently, a modified example of the triangular cone 1 of the present embodiment will be described.

FIG. 4 is a perspective view showing a configuration of a modified example of the triangular cone 1 of the present embodiment.

The triangular cone 1 shown in FIG. 4 differs from the triangular cone 1 of FIG. 1 in that the top of the main body 10 is removed and an opening 13 is provided in the upper portion of the main body 10. The size of the diameter of the upper portion of the main body 10 is set so that the ring of the cone bar 60 can be attached.

FIG. 5 shows an example of the cone bar tape 20 stored in the main body 10. The cone bar tape 20 is housed in a case 80. When the cone bar tape 20 is pulled, the cone bar tape 20 is pulled out from the case 80. When the take-up button 81 arranged at the center of the case 80 is pressed, the pulled-out cone bar tape 20 is taken up in the case 80. When the cone bar tape 20 is housed inside the main body 10, the winding button 81 can be operated from the opening 13. When the cone bar tape 20 is pulled out too much, the cone bar tape 20 can be adjusted to an appropriate length by operating the winding button 81. In the case of the triangular cone 1 having no opening in the upper portion of the main body 10 shown in FIG. 1, the cone bar tape 20 having no winding button is stored.

The opening 13 may have a size such that the winding button 81 of the cone bar tape 20 housed inside the main body 10 can be operated. As the opening 13 is smaller, the height of the triangular cone 1 can be secured, and the loss of the function as the safety fence can be minimized.

The configuration in which the opening 13 is provided in the upper portion of the main body 10 is an example, and a window capable of operating the winding button 81 of the cone bar tape 20 may be provided on the side surface of the main body 10. The configuration in which the opening 13 is provided on the upper portion of the main body 10 is preferable because the winding button 81 can be operated from any direction of the triangular cone 1. Further, a conical crown may be attached to the opening 13.

Next, another modified example of the triangular cone 1 of the present embodiment will be described.

FIG. 6 is a side view showing the configuration of another modification of the triangular cone 1 of this embodiment. FIG. 7 is a sectional view taken along the line AA.

In the triangular cone 1 shown in FIG. 6, the outlet 11 reaches the opening 13 at the top of the main body 10. The main body 10 also has a similar outlet 11 on the back side of FIG. The upper part of the main body 10 is divided into two main body upper parts 10A and 10B.

A table 14 for mounting the cone bar tape 20 is attached to the lower side of the outlet 11 inside the main body 10. The table 14 is fixed to the side surface inside the main body 10 with a screw 15 below the outlet 11. As shown in FIG. 7, the base 14 is a circle having a diameter smaller than that of the opening 13. The cone bar tape 20 placed on the stand 14 is one that fits on the stand 14. The table 14 includes fixing portions 14A and 14B having a width narrower than that of the outlet 11, and the fixing portions 14A and 14B are fixed to the main body 10 at positions corresponding to the outlet 11. The base 14 may be fixed to the main body 10 by using an L-shaped metal fitting instead of the fixing portions 14A and 14B. Gaps 16</b>A and 16</b>B exist between the base 14 and the side surface inside the main body 10. When another triangular cone 1 is inserted from the opening of the base 12, the main body upper portions 10A and 10B of the other triangular cone 1 can be inserted into the gaps 16A and 16B, so that the triangular cones 1 can be stacked. When stacking the triangular cones 1, the cone bar tape 20 may be stacked with the cone bar tape 20 stored therein, or may be stacked after the cone bar tape 20 is taken out. By providing the fixing portions 14A and 14B so as to be rotationally symmetric, it is not necessary to align the triangular cones 1 in one direction when stacking them.

FIG. 8 is a cross-sectional view of the triangular cone 1 according to another modification at the position of the base 14. A triangular cone 1 according to still another modification is provided with only one outlet 11 and a base 14 fixed at one place below the outlet 11. More specifically, the fixing portion 14A is provided only on one side of the base 14, and only one side of the base 14 is fixed below the outlet 11 of the main body 10. An L-shaped metal fitting may be used instead of the fixed portion 14A. Even when the base 14 is fixed and one outlet 11 is provided as shown in FIG. 8, the upper portion of another triangular cone 1 is adjusted so that the outlet 11 of another triangular cone 1 corresponds to the fixing portion 14A. The triangular cones 1 can be stacked by inserting the into the gap 16 between the base 14 and the main body 10. By using only one take-out opening 11, it is possible to prevent the strength of the upper part of the triangular cone 1 from being lowered.

As described above, according to the present embodiment, the triangular cone 1 has the hollow main body 10, the outlet 11 formed on the side surface of the main body 10, and the installation portion arranged inside the main body 10. When the safety bar is installed on the road side of the stopped work vehicle 100 by incorporating the cone bar tape 20 inside the main body 10 and taking out the tip end to which the string 21 is attached from the outlet, the triangular cone 1 is arranged, Since it is only necessary to pull out the cone bar tape 20 and attach it to another triangular cone 50B, it is possible to install the security fence more easily.
