Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sign pole for preventing a pedestrian from crossing a roadway by standing upright on a road surface at a centerline or a median strip of a roadway or at a boundary portion of a sidewalk.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, a steel fence b is provided at a median strip a of a road in order to prevent a pedestrian from crossing a road c. However, when such a steel fence b is provided, there is an inconvenience that, when a vehicle or the like collides with the fence b, the vehicle or the fence b may be damaged, leading to a secondary accident.

[0003] Here, in order to improve the above disadvantage, there is a hollow standing road sign disclosed in, for example, Japanese Patent No. 1451316. In this road sign, a required number of road sign columns composed of an elastic body and a hollow standing body are provided at predetermined intervals on a road surface, thereby restricting crossing or separating a sidewalk. In this way, by providing the road sign pillar made of an elastic body and a hollow standing image body, the road sign pillar itself is elastically deformed even if a vehicle collides, so that damage to the vehicle, the road sign pillar, and the like can be prevented. . Moreover, even if it is damaged, it is possible to reduce the risk of a serious secondary accident.

[0004] However, the above-mentioned Patent No. 1451316
However, even if an attempt is made to use a road sign disclosed in Japanese Patent Application Publication No. H11-107, a gap is provided between adjacent road sign columns, pedestrians can pass freely. As shown in the figure, if there is a pedestrian crossing e at a position distant from the station d, even if a required number of columns of the road sign columns f are provided in order to regulate the crossing from the vicinity of the station, a person can pass between the road sign columns f. There was the inconvenience of crossing through.
For this reason, the inconvenience is improved by using a road signpost as shown below.

Referring to FIG. 9, a description will be given of a road sign post for improving the above-mentioned inconvenience. The road sign pillar 100 shown in FIG. 9 is made of an elastic body and is integrally formed in a substantially T-shape. Specifically, as shown in FIG.
The sign pillar main body 101 and the beam 103 are integrally molded, the sign pillar main body 101 and the beam 103 which are separate components are integrally provided by a casting method, the sign pillar main body 101
And the beam 103 is fixed to the marker pillar main body 101 with rivets. In this case, a pedestal 1 for erecting the road sign pillar 100 on the road surface
Reference numeral 09 is also provided integrally below the marker pillar main body 101.

[0006] The generally T-shaped road sign pillars 100 integrally provided as described above are provided in a required number of rows (not shown), and the projecting beams 103 of the respective road sign pillars 100 are fixed and used. Thus, the above-mentioned Patent No. 14513
No. 1 at the interval between the road signs disclosed in Japanese Patent No. 16
Since No. 03 is located, the pedestrian cannot cross the road unless the pedestrian crosses the beam 103 or the like, so that crossing can be prevented.

[0007]

However, the substantially T-shaped road sign post 100 of the related art has the following disadvantages because it is integrally formed in the manufacturing process.

First, since the road sign pillar 100 is integrally formed in the manufacturing process, the road sign pillar 100 is manufactured and transported.
There is an inconvenience that workability deteriorates because the overhanging beam 103 is in the way and difficult to handle.

Secondly, the road sign post 100 is packed in a storage box 110 such as a cardboard box and transported to the installation site after the production is completed, but as shown in FIG. There is an inconvenience that the space inside the storage box 110 is increased, and many road sign posts 100 cannot be transported at one time.

Third, as described above, time and labor are required due to the deterioration of the work efficiency at the manufacturing site and the deterioration of the transportation efficiency to the installation site, and the cost for the manufacturing operation and the transportation operation is increased. There was an inconvenience.

Fourth, the screw-in type beam 103 can be easily installed at an installation site because of its easy installation. However, a hard material must be used as the material of the beam 103 in order to prevent breakage of the screw portion due to, for example, galling during the screwing operation, and if the beam 103 hangs down by its own weight and deteriorates its appearance. There is a problem that it is difficult to apply other materials other than the hard material, and the aesthetic appearance remains deteriorated.

Fifth, although the beam 103 fixed with rivets can be assembled at the installation site, there is an inconvenience that the operation takes time.

An object of the present invention is to provide an inexpensive road sign pole which can solve the disadvantages of the conventional example, can improve the production efficiency and the transportation efficiency, and has an excellent appearance.

[0014]

As described above, the road sign pillar according to the present invention is provided with its components detachably provided separately, so that it is possible to eliminate a situation in which a protruding beam becomes a hindrance as in the conventional example at a manufacturing site. Therefore, manufacturing workability can be improved. Further, in the transportation step to the installation site, for example, the storage box as in the conventional example can be stored in the storage box without creating useless space, so that the transportation efficiency can be improved. And because of this, it is possible to shorten the time related to the manufacturing operation and the transportation operation and reduce the number of labor,
The cost can be reduced.

Further, the beam is fixed to the marker column main body by at least two fixing members having a clamping portion capable of holding the beam together with the marker column body, and a locking member for locking the separation of the clamped fixing members. Conventionally, the beam itself is screwed by using the fixing mechanism having the structure or the fixing member having the first engaging portion that engages with the marker pillar main body and the second engaging portion that engages with the through hole provided in the beam. Other materials can be applied to the beam material as compared to the example. For example, in the case where the beam hangs down under its own weight, by applying another material (for example, a lighter material), it is possible to prevent the beam from hanging down and improve the appearance.

Further, by extending the holding portion of the beam in each fixing member of the fixing mechanism in the axial direction of the beam, it is possible to prevent the beam from drooping and improve the appearance. Further, by setting the hardness of the beam to durometer A95 or more, it is possible to obtain an unprecedented excellent road sign pole that can prevent drooping and improve the aesthetic appearance.
