Description

The present invention relates to a road cone such as a color cone (registered trademark) mainly used for indoor line construction, a folding display as a warning display, and a construction barricade or display using a plurality of the display. Is.

In the indoor line construction, the road cone is used for "securing a section", "calling attention", and the like. Unlike road cones used outdoors, road cones used for indoor line construction do not require "internal lighting", and because there is no risk of being blown away by the wind, "movement prevention equipment (weights, etc.)" is not required. In many cases, lightweight and simple ones are often used.

At the indoor line construction site, the space for storing materials and equipment is limited, and there is a problem with the storage of road cones when not in use. In addition, it is difficult to transport because it is bulky to put together multiple pieces. In contrast, foldable and prefabricated road cones are also used.

The foldable color cone (registered trademark) shown in Patent Document 1 can be expanded and contracted in the vertical direction in a bellows manner in the installed state. Specifically, the road cone is an integrated type consisting of an upper cone, an annular tube composed of a multi-stage cone-shaped telescopic tube, and a cone stand, and the upper part of the cone is pulled up in a direction to be separated from the cone stand, and the annular tube is appropriately used. It can be adjusted to any height.

Further, the color cone (registered trademark) of Patent Document 2 is an assembly type. This is done by providing a vertical fold curve that folds the pyramid body or the conical body in half and a protrusion at the lower end edge, drilling a hole of the same shape in the double-folded seat plate, and the side or edge of the hole in the seat plate. It is configured so that it can be fitted and assembled along the above.

At that time, since the bottom surface in contact with the floor or the ground has a key shape, the installation area is extremely small as compared with the conventional conical shape. Therefore, it does not take up space. In addition, when not needed, each small plate can be expanded and flattened as a single piece, or can be stacked and folded, saving space for storage and transportation. It is also convenient to carry when folded in layers.

Further, according to the invention of claim 3, since each small plate has a vertical notch, it is possible to prevent further expansion of each small plate by passing a string through the notch. It is also possible to prepare two folding indicators and pass both ends of the plate-shaped bar through the notches of each folding indicator to make a barricade that is off limits or off limits. Of course, it can also be used as a display in this case.

Further, according to the invention of claim 4, since the stopper is attached, the bending angle of each small plate body is maintained, and it can be widely used as a display such as a road cone.

Further, according to the invention of claim 5, by providing the pedestal at the lower end of the folding display, the shape of each small plate body is maintained in the bent state, and each small plate body does not fall down and is stable. Stand up. Therefore, it can be widely and stably used as a display such as a road cone.
