Description

The present invention relates to a load cone (so-called color cone: registered trademark), which is a safety device.

Road cones are often used as safety equipment at accident/construction sites, streets, event venues, and the like.
Regarding the load cone, there is no separate standard in JIS or the like. However, most of them have a conical main body and a square pedestal on the lower side of the main body (Fig. 1 of Patent Document 1, etc.).

Japanese Utility Model Laid-Open No. 55-145518

A load cone may be used alone, but may also be used by organically connecting multiple load cones so that a cone bar is installed between the load cones to form a regulation zone. .
In addition, since the main body of the load cone is hollow, a plurality of load cones can be superimposed for storage and movement.
At this time, since the pedestal is square, it gives a messy impression unless the directions of the pedestal are aligned.

Therefore, the inventor of the present application has completed the present invention in order to solve the above-described problems of the conventional road cone and to provide a road cone with improved convenience and design.

A first invention of the present invention is a load cone for a safety device comprising a conical main body and a pedestal wider than the main body on the lower side of the main body, wherein the pedestal has a circular cross section. It is characterized by being formed in
The second invention is that the pedestal has a diameter equal to one side of the conventional pedestal having a square cross section of the existing load cone, and a height higher than that of the conventional pedestal. It is the same road cone characterized.
A third aspect of the present invention is the same load cone characterized in that both side edges of the pedestal in longitudinal section are curved.
A fourth aspect of the present invention is the same load cone characterized in that both side edges of the pedestal in longitudinal section are tapered.
A fifth aspect of the present invention is the same load cone characterized in that all or part of the pedestal is made of a high specific gravity material.

The present invention has the following effects.
(1) Since the pedestal portions of the load cones are formed to have a circular cross section, the pedestal portions are always oriented in the same direction even when a plurality of load cones are installed, and there is no need to align the pedestal portions. Therefore, the installation of the load cone is completed only by arranging the load cone at a predetermined position. Likewise, when stacking a plurality of load cones, it is not necessary to align the directions of the pedestals. It leads to work efficiency (shortening of working hours, etc.) when using the road cone.
(2) Since the pedestal portion of the load cone is formed to have a circular cross section, the pedestal portion has no corners, so that the foot or the like can be prevented from coming into contact with the corners of the pedestal portion and stumbling, thereby improving safety.
(3) Since the pedestal portion of the load cone is formed to have a circular cross section, the load cone can be moved while being rolled by tilting the load cone so that the side surface of the pedestal portion is in contact with the ground. In the case of the load cone, which is popular these days and integrates the pedestal and the cone bed (weight), it is necessary to lift and move the load cone, which is quite hard work (especially transporting the load cone in layers). If it can be rolled and moved, the road cone can be transported very easily.
(4) By forming the pedestal portion of the load cone to have a circular cross-section, the shape of the entire load cone is rounded and the feeling of oppression is eliminated. Therefore, it becomes a mark to feel kindness.
(5) The pedestal portion of the load cone has a circular cross section and both side edges of the longitudinal section are curved (doughnut shape), so that the load cone can stand on its own in a slanted state (has self-supporting capability). For example, when a load cone that is being carried diagonally reaches a predetermined position, it can stand on its own simply by letting go of the hand. In addition, even if one of the pedestals of the road cone installed outdoors is blown up by the wind, the angle at which it returns to its original position is large, so it is easy to return to its original position (it has a resilience).

An embodiment of a load cone according to the present invention will be described below with reference to the drawings.

1 to 4 are explanatory diagrams showing a first embodiment of the load cone 10. FIG.
As shown in the left diagram of FIG. 1 , the load cone 10 includes a conical body portion 20 and a pedestal portion 30 wider than the body portion 20 below the body portion 20 . Then, the pedestal portion 30 is formed in a “cylindrical shape” having a circular cross section.
The right view of FIG. 1 shows the load cone 10 from the bottom, but the main body 20 is hollow (the same applies to other embodiments). As a result, they can be superimposed in the same manner as conventional load cones.

FIG. 2 illustrates the pedestal 30. As shown in FIG.
FIG. 2(a) shows the dimensions of the pedestal portion of the currently popular cone bed (weight) integrated load cone. According to this, its volume is 35 cm x 35 cm x 4 cm = 4900 cubic cm, and if 1 g/1 cubic cm, its weight is 4900 g.

If this pedestal portion is made into a cylindrical pedestal portion without changing the height, the dimensions are as shown in FIG. 2(b). That is, 19.7 cm×19.7 cm×3.14×4 cm=4.874 cubic cm≈4900 cubic cm (4900 g). Then, the diameter becomes 39.4 cm (19.7 cm×2), and the width becomes 12.5% larger than that of the pedestal shown in FIG. In this case, the cone bed (weight)-integrated load cone, which is currently in widespread use, is larger in size, and convenience is impaired.

Therefore, if the pedestal has the same volume (weight) as that of FIG. (17.5 cm x 17.5 cm x 3.14 x 5.1 cm = 4904 cubic cm (4904 g) = 4900 cubic cm (4900 g)).

Fig. 3 shows a state in which the load cones are piled up for transportation (because the cone bed (weight) integrated load cones are heavy, the number that the worker can carry at one time is about 3). be).
The left diagram in FIG. 3 shows a currently popular cone bed (weight) integrated load cone superimposed, and the overall height is indicated by "X". The right view of FIG. 3 shows a state in which the load cones 10 provided with the pedestals 30 having the dimensions shown in FIG.
Both road cones have the same weight and width (which is the width of the pedestal), and differ only in height (X<Y), which is only 3.3 cm (4 cm x 3-5.1 cm x 3=-3.3 cm). It can be said that the labor of transporting both stacked load cones is almost the same for workers. That is, even if the currently popular square pedestal portion is replaced with the columnar pedestal portion 30 shown in FIG.

Rather, there are many merits of using the cylindrical pedestal portion 30 .
First, as shown in the left diagram of FIG. 1, the load cone 10 has the same appearance when viewed from any direction because the pedestal portion 30 is cylindrical. Therefore, even if a plurality of load cones 10 are installed or superimposed, the orientation of the pedestals 30 is always the same, and there is no need to align the orientations of the pedestals. Very convenient to handle.
Next, since the pedestal portion 30 has no corners, it is possible to prevent damage caused by contact with the corners of the pedestal portion 30, such as a foot or an object, resulting in high safety. In addition, since the pedestal portion 30 has no corners, the overall form of the load cone 10 is rounded, and a person coming into contact with the load cone 10 does not feel oppressed. The road cone 10 serves as a mark for feeling kindness.

Furthermore, as shown in FIG. 4, when the load cone 10 is tilted so that the side surface of the pedestal portion 30 is in contact with the ground, the load cone 10 can be moved and transported while being rolled. A load cone having a conventional square-shaped pedestal cannot be moved and transported in this way. In particular, it is effective in the case of a load cone in which a heavy pedestal and a cone bed (weight) are integrated.

5 and 6 are explanatory diagrams showing a second embodiment of the load cone 10. FIG.
The second embodiment differs from the first embodiment in the shape of the pedestal. The pedestal portion 40 of the second embodiment has a so-called “doughnut shape” having a circular cross section and curved side edges on the vertical cross section. This provides the same merits as in the first embodiment.

Advantages peculiar to the doughnut-shaped pedestal 40 are those shown in FIG. That is, the load cone 10 in an oblique state is provided with the pedestal portion 40 so that it can stand on its own (has self-support). As a result, when the load cone 10 being carried obliquely reaches a predetermined position, it can be placed as it is by releasing the hand. In addition, even if one of the pedestals of the road cone 10 installed outdoors is blown up by the wind, it can easily return to its original position (having a restoring force) because of the large return angle. Although it is necessary to raise the fallen load cone after a storm, an earthquake, or the like, such work is not necessary with the load cone 10 having the donut-shaped pedestal portion 40. - 特許庁

7 to 9 are explanatory diagrams showing third to fifth embodiments of the load cone 10. FIG.
The third to fifth embodiments differ from the first embodiment in the shape of the pedestal portion, as in the second embodiment.
In the load cone 10 of the third embodiment, the pedestal portion 50 is formed to have a straight tapered shape on both longitudinal cross-sectional side edges. It is the so-called "skirt type".
In the load cone 10 of the fourth embodiment, the pedestal portion 60 is tapered such that both side edges of its longitudinal section are curved. It is a so-called "bowl type".
In the load cone 10 of the fifth embodiment, the pedestal portion 70 is formed in a disc shape. It is a so-called "hat type".

The pedestals 30 to 70 may be entirely or partially made of a high specific gravity material so as to form the cone bed (weight) integrated load cone 10 . In particular, since the pedestal 70 is disc-shaped, it is necessary to form all or part of it from a material with a high specific gravity.

The load cone according to the present invention may be used alone, or may be used by connecting a plurality of load cones with a cone bar or the like. It can be widely used at accident sites, construction sites, event sites, etc., by lightening the burden on workers and installers.
