A step portion which is formed of a flexible material and has a thinner wall around the connection portion to the display portion than the other portion of the support portion, and further has a step portion contacting the road surface along the outer periphery of the bottom surface. It is characterized by that.

によって大きなものとなる。この結果、倒れようとする
表示部は、もとの直立位置に戻る。[Operation] In the construction safety cone of the present invention having the above-mentioned configuration, since the support portion provided on the outer periphery of the lower end of the display portion is made of a flexible material having elasticity, for example, the vehicle comes into contact with the display portion and When tilted, the support part bends with the tilt, and the stored elastic energy gives the display part a restoring force that opposes the motive force in the falling direction. This restoring force becomes large when the plate-shaped portion of the support portion is deformed and the step portion around the connection portion is deformed. As a result, the display unit that is about to collapse returns to its original upright position.

すかったといえる。Further, as shown in the schematic view of FIG. 1 (A), when the display portion A1 is inclined, the following behavior is exhibited. That is, as described above, the stepped portion that is thinner than the other portions of the support portion B1 is formed around the connection portion of the support portion B1 to the outer periphery of the lower end of the display portion A1. Therefore, the display portion A1 is rotated and tilted around the portion P1 in which the stepped portion near the lower end thereof is disposed, so that the position of the center of gravity G1 of the display portion A1 does not become high and the center of gravity G1 is The amount of horizontal movement is also small. By suppressing the movement amount of the center of gravity G1, the display unit A1 is more likely to return to the original upright position. In this respect, conventionally, as shown in FIG. 1 (B), the display portion A2 and the support portion B2 are integrally formed of a hard material, and the display portion A2 is centered on the end portion P2 of the support portion B2. Since it rotates and tilts, the position of the center of gravity G2 becomes higher, and the amount of movement of the center of gravity G2 in the horizontal direction also increases, and it can be said that it was easy to fall.

考案の工事用安全コーンは一層倒れにくい。Further, since the construction safety cone of the present invention is provided with the stepped portion which is in contact with the road surface along the outer periphery of the support portion formed of the flexible material having elasticity, for example, when the vehicle is accidentally contacted. When the display part receives momentary force, when the support part tries to separate from the road surface, the stepped part,
Due to the plate-like portion which is slightly spaced from the road surface due to the stepped portion and is closer to the road surface side due to the weight of the display portion, the support portion exerts an attraction force to the road surface. Due to this suction force, the construction safety cone of the present invention is more difficult to fall.
また、本考案の工事用安全コーンにおいては、支持部B1

撓材により形成されているから破損することはない。In addition, in the construction safety cone of the present invention, the support portion B1
Even if the vehicle accidentally rides on the plate-shaped portion, the supporting portion B1 is formed of a flexible material and therefore is not damaged.

A stepped portion 7 is provided around the entire circumference of the stepped portion 7 and. As shown in FIG. 3, the stepped portion 7 is formed continuously from the plate-shaped portion and curved toward the front side. In the example,
The thickness t1 is formed to be slightly smaller than the thickness t2 of the plate portion. Corner C, which is the connecting portion between the step 7 and the plate-like portion
In, the front side is formed by a roundness having a small radius R1, and the back side is formed by a roundness having a relatively large radius R2.

The connection portion 5 and the display portion 1 are fixed by the caulking member 9 or the like. A collar portion 11 that supports the lower end of the display portion 1 is formed inside the step portion 7.

の厚みt3は２［mm］程度のものである。A stepped portion 13 is integrally formed on the bottom surface of the support portion 3 along the entire circumference thereof. In the embodiment, the stepped portion 13
Has a thickness t3 of about 2 [mm].

との直立位置に戻る。In the construction safety cone of the embodiment thus configured, since the support portion 3 provided on the outer periphery of the lower end of the display portion 1 is made of a flexible material having elasticity, for example, a vehicle comes into contact with the display portion 1 When tilted, the support part 3 bends in accordance with the tilt, and the stored elastic energy gives the display part 1 a restoring force that opposes the kinetic force in the falling direction. This restoring force becomes large when the plate-shaped portion of the support portion 3 is deformed and the step portion 7 having a thickness slightly smaller than that of the plate-shaped portion is deformed. As a result, the display unit 1 that is about to collapse returns to the original upright position.

は、一層、もとの直立位置に戻りやすくなる。Further, in the embodiment, the corner portion C, which is a connecting portion between the step portion 7 and the plate-like portion, is sharply configured by the minute roundness R1 on the front side and is gently configured by the large roundness R2 on the back side.
Further, since the step portion 7 is formed thinner than the other portions of the support portion 3, the support portion 3 is easily bent at the corner portion C. Therefore, when the display section 1 is tilted, the support section 3 is bent at the corner C, and the display section 1 is rotated and tilted about a portion near the lower end thereof, so that the center of gravity of the display section 1 is changed. It does not increase, and the amount of movement of the center of gravity in the horizontal direction also decreases. By suppressing the movement amount of the center of gravity, the display unit 1
Is more likely to return to its original upright position.

れにくい。Further, when a momentary force acts on the display unit 1 such as when the vehicle accidentally comes into contact, the support unit 3 is provided along the outer periphery of the bottom surface of the support unit 3 when the support unit 3 tries to separate from the road surface. From the stepped portion 13 and the plate-like portion which is slightly spaced from the road surface by the stepped portion 13 and approaches the road surface side due to the weight of the display unit 1, the support portion 3 is attracted by the road surface.
Due to this suction force, this construction safety cone is more difficult to fall down.

This measurement was carried out on a conventional construction safety cone having substantially the same size as the example, and it was found that

ある。Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, a structure in which a step portion is intermittently provided around the connection portion of the support portion to the display portion, or the support portion is provided. It is needless to say that the present invention can be implemented in various modes without departing from the scope of the present invention, such as a configuration in which a plurality of stepped portions are provided along the outer periphery of the bottom surface of the vehicle so as to contact the road surface.

きわめて倒れにくいという優れた効果を奏する。Effects of the Invention As described above in detail, according to the construction safety cone of the present invention, even if the vehicle accidentally comes into contact and the cone-shaped display portion tilts, the support portion around the lower end falls to the display portion. Since a restoring force that opposes the kinetic force of the direction is given, it immediately returns to the original upright position. Further, since the display unit rotates and tilts around the portion where the thin-walled step portion is disposed, movement of the center of gravity of the display unit due to tilting is suppressed. Further, due to the action of the stepped portion provided along the outer circumference of the bottom surface of the support portion, the support portion is attracted to the road surface. For this reason,
It has an excellent effect that it is extremely hard to fall down.
