[Prior art]

 Conventionally, as a display pillar, the display and coloring such as distance, guidance, guidance, etc. have been made directly on the side surface of a pillar made of synthetic resin, metal, concrete or the like.

[0003]

[Problems to be solved by the device]

 Display pillars are required to be installed so that the surrounding landscape is not damaged and the necessary information displayed on them can be accurately transmitted. Therefore, the display pillars have different colors and sizes depending on the purpose of installation, location, display contents, etc., and the types are also diversified. For example, the distance display pillars, which are mainly installed along roads for road management and display the distance from the starting point of the road, have different types of distance display for each item, so the number of types is huge. There is.

However, in the conventional display column as described above, since the display and coloring are directly made on the side surface of the columnar body, it is difficult to mass-produce and it is troublesome to manufacture and the diversified type as described above is used. Couldn't handle enough. In addition, when the display content of the display pillar was changed after it was once installed, it was necessary to replace the display pillar, which was a troublesome task.

Further, in the above-mentioned display pillar, since the normal display or coloring is provided on the side surface of the columnar body made of normal synthetic resin, metal, concrete, etc., the display becomes difficult to see at night, and the visual confirmation at night is made. The sex was inferior. For this reason, there is a case where the above-mentioned display is printed on a reflection sheet and the reflection sheet is attached to the side surface of the columnar body in order to improve night visibility, but the reflection sheet is very expensive and the reflection sheet can be attached. It was a lot of work. Further, since the reflection sheet has low reflection brightness, it is inferior in visibility from a long distance and is not sufficient.

In view of the above, the present invention solves the above-mentioned problems of the related art, makes it possible to easily change the display content even after being manufactured at low cost by mass production and installed, and which has excellent visibility at night. It is intended to provide pillars.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view showing an embodiment of a display column of the present invention, FIG. 2 is an exploded perspective view of the display column of FIG. 1, FIG. 3 is a cross-sectional view of FIG. 1, and FIG. 4 is a display column of FIG. FIG. 3 is a partial cross-sectional perspective view showing an example of a display body.

In the drawings, 1 is a columnar body made of a synthetic resin such as ABS resin, polypropylene, vinyl chloride resin or the like, or a metal such as aluminum or steel. At least one side surface of the columnar body 1 is a smooth surface 11 having the same width over the entire length, and the inside thereof is hollow for weight reduction. Regarding the method for producing the columnar body 1, usually, the synthetic resin or metal is continuously molded into a long hollow columnar body by an extrusion molding machine or a pultrusion molding machine, and then the long hollow columnar body is appropriately lengthened. The method obtained by cutting into pieces is preferably used.

It is preferable that the shape of the columnar body 1 is a substantially triangular columnar shape in which two side surfaces are smooth surfaces 11 as shown in FIGS. 1 to 3, but a part of the side surface is notched along the longitudinal direction. It may be a cylinder having a smooth surface formed as a result, a curved columnar shape such as an elliptic cylinder, or a prismatic shape having a large number of side surfaces as a smooth surface such as a quadrangular prism or a polygonal prism.

At both ends of the smooth surface 11, L-shaped holding edges 12 are formed inwardly facing each other along the length direction. The holding edge 12 is usually integrally formed of the same material as the columnar body 1, but the members of the holding edge 12 may be separately manufactured and attached to both ends of the smooth surface 11. .

In order to increase the bending strength of the hollow columnar body 1, it is preferable that a reinforcing bar 14 is provided between the inner walls of the side surfaces in the longitudinal direction as shown in FIG. The reinforcing bars 14 are made of synthetic resin or metal, and vertical plates 16 having concave grooves 15 formed on the side edges are radially arranged, and the concave grooves 15 are formed on the inner wall of the columnar body 1. It is engaged with the ridge 17 and attached to the inner wall of the columnar body 1. Of course, the reinforcing bar 14 may be omitted, or the same material as that of the columnar body 1 may be integrally formed.
