[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence, and more particularly, to a fence used for a road, a street, a passage in a facility, or the like.

[0002]

2. Description of the Related Art Generally, in order to separate a boundary between a roadway and a sidewalk, a fence body having a cross bar between the columns is provided via a joint bracket attached to a column standing at an appropriate interval. is set up.

[0003] In this fence structure, one of the two-part brackets developed earlier by the applicant is bolted to a support,
A horizontal rail is sandwiched between one of the brackets and the other bracket and attached with bolts (see Japanese Utility Model Laid-Open No. 59-140320). The vertical rail extends longitudinally inside the hollow horizontal rail. A plate which is mounted on a column with mounting bolts penetrating through the hollow horizontal rail together with the vertical plate (see Japanese Utility Model Laid-Open No. 62-26418).
Alternatively, the joint bracket is formed by a pair of mounting brackets provided with clamping pieces on both sides of the column clamping section, and at least one of the locking pieces projecting inside the column clamping section is drilled on the side of the column body. That are to be locked in the locking holes

[0004] On the other hand, conventionally, sidewalk fences and traffic signs are provided separately, and although both aesthetic and constructional problems have been encountered, they have been neglected.

[0005]

However, the technique described in Japanese Utility Model Laid-Open Publication No. 59-140320 has a problem that the bracket is attached to the column with a plurality of bolts, so that it cannot be applied unless the column has a large diameter. Also, since the brackets are bolted and the horizontal rails are inserted and bolted into the through holes formed by both brackets, the horizontal rails are installed in an inclined shape or bent in a horizontal plane. When the fence was installed on an inclined ground or bent on a horizontal plane, the joint bracket had to be changed in design. 62-26
The technique described in Japanese Patent No. 418 has a structure in which a mounting bolt penetrates a horizontal rail and a support body, so that it cannot be applied to a sloping ground as described above, and the bolt head is exposed to the outside side. Therefore, the appearance was impaired and it was dangerous for pedestrians. The technique described in Japanese Utility Model Laid-Open Publication No. 2-101816 has a structure in which a pair of mounting brackets is used to hold a column and a crosspiece. In this method, the locking piece formed on the mounting bracket is locked in the locking hole formed in the support body, so that it is necessary to make a hole in the support body at the site, resulting in poor assembly workability. was there. In addition, since the bolts and bolts penetrate the crosspieces held between the holding pieces, the bolt heads and nuts are exposed to the outside to impair the aesthetic appearance as described above and pose a danger to pedestrians. Was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and allows a cross beam to be easily erected on a pillar body without exposing a bolt head or the like to the outside and to a sloped land without changing the design. It is an object of the present invention to provide a fence body capable of coping with the installation of a building. Furthermore, by making the fence post also available as a pole post,
It is intended to be able to respond to environmental beautification around the fence body.

[0007]

In order to achieve the above-mentioned object, the fence of the present invention comprises a plurality of columns which are erected at appropriate intervals and a joint bracket which is attached to the columns. On the premise of a fence consisting of a crosspiece to be erected, the support body has a narrow opening-shaped fitting groove that opens to the outside along the longitudinal direction, and the joint bracket has an angle with the fitting groove. A lower bracket body having a connecting piece that is adjustably attached, an upper bracket body that cooperates with the lower bracket body to form a through hole of the horizontal rail, and a fixing bolt and a nut that fixes these bracket bodies. (Claim 1).

In the present invention, in addition to the above configuration,
It is preferable that the support body has a narrow opening-shaped fitting groove that opens to the outside along the longitudinal direction, and that a pole receiving piece is protrudingly provided inside the pillar of the fitting groove.

The shape and structure of the joint bracket are not limited as long as the joint bracket can be attached to the fitting groove provided in the support so that the angle can be adjusted. Is formed in a U-shape, a mounting hole is formed in the connecting piece, a contact surface between the lower bracket body and the upper bracket body is formed in an inclined shape, and a step which engages with both contact surfaces with each other. It is better to form a part (claim 3).

The material of the support, the joint bracket and the crosspiece may be any material as long as it has high corrosion resistance and durability. Preferably, the support and the crosspiece are made of an extruded aluminum alloy. It is preferable that the lower bracket body and the upper bracket body constituting the joint bracket are formed of an aluminum alloy casting, and it is more preferable that these surfaces are subjected to, for example, baking coating made of polyurethane resin.

The lower end of the support may be buried and fixed in the ground as usual, but it may be fitted in a hole in the ground, or may be a standing member such as a base plate to make it portable. Or the like attached to

According to the fence of the present invention configured as described above, the connecting piece of the lower bracket is attached to the fitting groove provided in the longitudinal direction of the support so that the angle can be adjusted. By inserting the horizontal rails into through holes formed in the body and the upper bracket body and fixing these bracket bodies with fixing bolts and nuts, the horizontal rails can be erected between the columns so as to be tiltable. (Claim 1). Therefore, even on a sloping ground, the horizontal rail can be erected in accordance with the inclination angle of the installation surface using the same joint bracket without changing the design of the joint bracket. Further, since the bolt head, the nut, and the like are not exposed to the outside, the appearance can be improved, and the danger of a pedestrian can be prevented.
