Description

The present invention relates to a portable color cone (registered trademark) formed to be foldable.

The present invention is a plastic that is formed into a hollow conical shape and colored red or orange as a device for traffic control at road construction sites, telephone lines and electric wire construction along roads, construction work sites, parking lots, etc. A lot of corn is used. Particularly at road construction sites, after the commuting time period ends, color cones are installed on the road at predetermined intervals, and are cleaned up after one day of construction. However, the conventional color cone is thick and heavy so that it will not be blown by the wind, and it can only be carried by stacking about three at the same time. In addition, loading and unloading from the truck bed is heavy labor, Since it is bulky, there is a problem that it cannot be transported in large quantities.

Also, when working on telephone lines and electric wires along the road, the bucket cars work while moving sequentially, so the guards standing beside them had to move with heavy color cones each time. . When vehicles are regulated at construction sites, not only are color cones installed, but traffic is also guided by waving red and green flags alternately. In addition, a blinking guide light is used at night. For this reason, the security guard had to move with a color flag and a guide light in addition to the color cone, which could be misplaced.

In addition, a color cone has been proposed that is lightweight, easy to carry, and easy to assemble on site. For example, a plurality of folding lines in the vertical direction of a half-folded pyramid body and a punched hole of the same shape that can fit the pyramid body into a two-fold seat plate are drilled, and the pyramid body is fitted into the hole in the seat plate There has been proposed a foldable color cone (Patent Document 1) configured so as to be assembled.

However, this color cone is made of wood, foam, paper cardboard, plastic cardboard, metal plate, etc., and is easy to transport and assemble, but foam and paper cardboard can be blown away by the wind, It is necessary to form the seat plate with a heavy material.

In addition, a base plate having a holder, a column inserted into the holder, a slide cylinder that slides around the outer periphery of the column, a slide ring fixed to the column, an interlock sleeve, and one end of the slide ring and the interlock sleeve can be freely rotated. There has also been proposed an umbrella-shaped foldable color cone (Patent Document 2) provided with a connecting rod attached to the open / close rod at the other end and a skirt covering the outer periphery of the open / close rod. Since the sign part and the base plate can be separated and the sign part can be folded like an umbrella, it is small and easy to store and transport.

However, since this umbrella-shaped foldable color cone is entirely covered with a skirt, it may be blown off by a strong wind, and the base plate must be formed of a heavy material. In addition, Patent Documents 1 and 2 do not have a space for storing color flags and guide lights, and have to carry them separately, causing a problem of misplacement.
