2. Description of the Related Art Conventionally, a protective fence for surrounding a dangerous place on a road or a factory, or a pillar material used as a pillar or a pillar of a display fixture or the like for displaying or installing articles at an exhibition hall or the like. Is known to be formed from a light metal or synthetic resin tube. The necessary electrical wiring is installed along the surface of the tube.

This electric wire is connected to a display panel, a buzzer, a lamp attached to a protective fence or a display fixture and a sensor for activating them, or a mechanical device installed in the protective fence or a display cabinet. The wiring is mainly performed on the back side of the pillar (the side opposite to the side where people pass) from the viewpoint of design and safety.

For example, FIG. 5 (a) shows a pillar material a used for a protective fence, the pillar material a being made of an aluminum alloy having an irregular cross section, and having a transparent upper end. A cap b made of a synthetic resin is mounted, and a blinking lamp (not shown) is provided in the cap b.

Further, one of the longitudinal ribs c has an electric wire insertion pipe f composed of pipe pieces d and e which can be divided into two.
It is made detachable by a bolt g. To attach an electric wire to the column member a, first, the pipe piece d is attached to one vertical rib c using a bolt g, and then the electric wire is pushed into the groove of the pipe piece d, and a predetermined After inserting an electric wire through the electric wire insertion hole i formed at the position and connecting the electric wire to an electric appliance, the pipe piece e is fitted to the pipe piece d to form a mode as shown in FIG. Here, h is a bundle of electric wires.

[0006]

However, in the above-mentioned conventional column material, an electric wire insertion pipe f for accommodating an electric wire is formed as a separate member from the column material a, and two pipe pieces d and e are used. Since it is divided, it takes time and trouble to assemble it from the state of FIG. 5 (a) to the state of FIG. 5 (b), and there is a problem that quick construction is not possible. A similar problem occurs in the case of removal.

Further, since the electric wire insertion pipe f attached to the column material protrudes from the column material, it interferes with the passage and work of a person, and external force acts on the electric wire insertion pipe f, thereby causing the electric wire insertion pipe f to become inoperable. There is a risk of breakage and cutting of the wires, as well as appearance problems.

In view of the above-mentioned prior art, the present inventor has devised that as a result of using the internal cavities of the pillars, it is possible to solve these problems at once, and to complete the present invention. It has been reached.

In other words, the present invention solves the above-mentioned problems of the prior art, which makes it easy to attach and remove the electric wiring to and from the pillar, does not impede the passage or work of people, and also has an external appearance. The purpose of the present invention is to provide an excellent pillar material.

SUMMARY OF THE INVENTION The present invention is based on the following object: "A part of a tube wall is cut out in a longitudinal direction to form an opening, and a convex or concave streak is provided at both ends of the opening. A pillar material having a concave or convex ridge that can be inserted into the convex or concave ridge at an edge, and an insertion wall provided with an electric wire insertion hole inserted into the opening. ”As its gist.

That is, according to the present invention, a part of the tube wall itself is formed as a separate body and made detachable with respect to the tube wall, and the inner wall of the pillar is passed through the electric wire from the separate wall. By introducing it, the main point is to eliminate the problem of workability, danger, and appearance problems by eliminating the need for an electric wire insertion pipe.

As the material of the column material of the present invention, all of the conventionally used materials are employed. Also, the cross-sectional shape of the column material is not particularly limited, and may have a circular, square or any other irregular cross-section as long as it is a tubular body. In the case of the present invention, since a part of the pipe is cut out in the longitudinal direction, vertical ribs are provided on the inner and outer wall surfaces of the pipe, or those provided with partition walls parallel to the pipe axis inside the pipe, These ribs and partition walls are preferable because they exhibit a reinforcing function.

In the present invention, the opening provided in the tube wall is not limited to the one in which the entire tube wall is cut out to form a crack, but may be a part thereof.
If it does not communicate with one of the tube ends, an insertion wall described later cannot be inserted.

In the present invention, the ridge or the ridge provided on the opening and the insertion wall may have only one of the ridge or the ridge on one of the ridges or the ridge.
In any case, both the ridges and the dents may be provided. In addition, the ridges include those in which the opening or the edge of the insertion wall is used as it is.

[0015] The insertion wall used in the present invention may be made of the same material as that of the tube or of a different material. It is preferable to use one having the same curvature as that of the torso of the body.Especially, when the insertion wall is inserted into the tube, a part of the tube wall is actually cut out in the longitudinal direction. Those having the appearance of a notch obtained as described above are preferred.

Further, the insertion wall may be an integral body continuously in the longitudinal direction, or may be one that can be divided into a plurality of parts. If the holes are provided, the electric wires can be easily inserted.

The electric wire insertion hole provided in the insertion wall is
As described later, an opening may be provided so as to communicate with both end edges of the insertion wall, and the position of the insertion hole is determined by the convenience of wiring.

[0018]

According to the column material of the present invention, an opening is formed by cutting a part of the tube wall in the longitudinal direction, and a convex or concave ridge is provided at both ends of the opening. Alternatively, since there is a concave or convex ridge that can be inserted into the concave ridge, and an insertion wall in which an electric wire insertion hole is drilled is formed by being inserted into the opening, a part of the tube wall itself is formed. By making it separate and detachable from the pipe wall, the internal cavity of the pipe can be used as a storage space for electric wires, and the electric wire insertion pipe does not protrude from the pillar.
