[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic control barricade for restricting a vehicle from entering a road construction site or the like.

[0002]

2. Description of the Related Art At the site of road construction and traffic accidents, barricades are built to control the entry of vehicles. Conventionally,
For the construction of this type of barricade, a cone-shaped sign called a color cone is often used, and the color cone is arranged around the site at an appropriate interval to restrict the entry of the vehicle. The tops of the color cones are often connected by connecting bars provided with fitting rings at both ends.

[0003] The above-mentioned color cone is rigid, so that it is liable to be bulky or collapsed during transportation, and is damaged when a vehicle or a person collides accidentally, or the color cone itself is damaged. Or there is a problem.

To cope with this problem, for example, Japanese Utility Model Laid-Open No. 4-1220 discloses a display part (standing part) connected to a stable part (base part), and this display part is made of a foldable soft synthetic resin material. There is disclosed an air-standing sign that is formed in a hollow shape and inflates the display unit by injecting air into the hollow.

[0005]

SUMMARY OF THE INVENTION The above-described conventional air-standing type signage is capable of extracting air and being foldable, and
Since it has a buffering action, the problem of the color cone can be solved.However, since the sign bodies are separately formed one by one, it is necessary to inject air into each sign body individually. There is a problem that it takes time to inflate and stand. In addition, when arranging the respective sign objects, it is necessary to position these installation intervals at an appropriate interval, for example, an interval corresponding to the length of the connecting bar, and there is a problem that it takes time to set at the installation site. .

An object of the present invention is to provide an air-standing type traffic control barricade which can be set at an installation site in a short time.

[0007]

In order to solve the above-mentioned problems, a traffic control barricade according to the present invention comprises a base portion grounded on a road surface, and an upright portion standing on the road surface, and at least the upright portion is provided. A plurality of signage members formed of a foldable soft sheet material in a bag shape and into which air is injected,
The inside of each of the sign bodies is connected in series by an air supply pipe whose pipe wall is formed of bellows and is expandable and contractible, and an air supply source is connected to the sign body on one end side connected in series. Are connected to an air supply pipe communicating with the inside of the sign body, and air is supplied from the air supply source from the air supply pipe connected to the sign body on one end side to connect the sign bodies. Air is injected into each of the sign bodies through an air supply pipe of the bellows, and the upright portions of the connected sign bodies are inflated and erected.

[0008] That is, a plurality of sign bodies into which air is injected are connected in series by an air supply pipe which has a bellows-shaped tube wall and can be extended and contracted, and is connected to the sign body on one end side. By supplying air from a single air supply source from a pipe, all connected sign objects can be inflated and raised in a short time, and the installation interval and arrangement shape of each sign object can be adjusted arbitrarily. Made it possible. In addition, by contracting the air supply pipe of the bellows, the barricade can be stored compactly, and transport is easy.

[0009] A bypass passage is provided for passing a part of the air supplied from the air supply pipe on the side of the air supply source into each of the sign bodies through the air supply pipe directly connected to the next sign body. Accordingly, air can be simultaneously injected into each of the connected sign objects, and the time for inflating and raising all the sign objects can be further reduced.
