DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer fence provided on a sidewalk of a park where people walk, such as a promenade.

[0002]

2. Description of the Related Art A conventional outer fence of this type has a structure in which a horizontal rail is hung on a column erected at a predetermined interval, and is made of a material made of wood or a concrete bar. Some have been used.

[0003]

The conventional outer fence is made of either wood or concrete bars.
There are two types of horizontal rails, which are simply attached along the side of the column with bolts, and those where the both ends of the horizontal rail are embedded and connected to the column, and this horizontal bar is positioned inside between the columns. In the case where the horizontal rail runs along the horizontal rail, this horizontal rail hinders pedestrians, and in the case where the horizontal rail is located inside the column, the structure of the joint between the horizontal rail and the column becomes complicated, and the cost increases. There is a problem.

A top tree is fixed to the upper end of each pillar. When the outer fence is bent, the ends of the top tree must be treated according to the bending angle. conventionally,
Since the top trees were machined at an angle corresponding to each bending angle, they were expensive for general-purpose students.

Further, the conventional outer fence has a function of easily distinguishing the sidewalk from the outside of the sidewalk, and generally lacks consideration for a disabled person passing through the sidewalk.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a good appearance and a good sense of contact with a human body in addition to a human-friendly form. It is an object of the present invention to provide an outer fence capable of having a property.

[0007]

In order to achieve the above-mentioned object, an outer fence according to the present invention comprises a column erected on the ground at a predetermined interval, and a laterally mounted laterally mounted at a middle of the column in the height direction. In the outer fence consisting of a crosspiece and a top tree along the upper end of each column, wood is used for these members, round materials are used for the column and the horizontal column, and the cross-sectional shape of the horizontal column is substantially set on the side of the column on the sidewalk side of the column. A groove is formed in which 1/2 is fitted, and a horizontal rail is fitted in this groove and bolted together. In addition, the ends of the horizontal rails are alternately combined and joined, and a bolt is inserted through the combined joint. Then, it is configured such that both ends of a through hole of each bolt are closed with a wooden plug.

In the above outer fence, a plug is formed at the upper end of each column, a groove provided on the lower surface of the top tree is fitted into this plug, and the end of the adjacent top tree and the column are connected to each other. Of the joint plate fixed to the upper surface of the plug body of the column is fixedly connected to the bottom surface of the groove of the adjacent top tree.

[0009]

[Operation] A horizontal beam is attached to a side surface of a pillar erected at a predetermined interval on the side of a sidewalk so that approximately half of the cross-sectional shape thereof is shifted to the side of the sidewalk. Further, the cross rails are staggered and joined at their respective ends in a staggered manner, and are bolted to the struts at this portion. The opening of the bolt hole for attaching this is closed with a wooden plug, so that the bolt and nut cannot be seen from the outside.

[0010] In addition, the top end of the post is fitted with a plug provided at the upper end of the post, the end of the top end is fitted with the plug of the post, and the top of the post is joined together with the adjacent top end by a joint plate. Attached to the plug.

The length of the cross bar 2 is an integral multiple, for example, twice as long as the interval between the columns 1, and both ends thereof are identical at the same cutting angle (for example, 30 °) as shown in FIG. The crosspieces are cut obliquely in the direction, and by joining these diagonally cut portions, the adjacent horizontal rails 2 are alternately combined and joined with the same diameter. Each of the horizontal bars 2 is fixed to the column 1 at the middle and both ends thereof.
A bolt hole 6B through which the bolt 5 penetrates is provided at a portion to be fixed. At the outer end of the bolt hole 6B, a nut 6 (or the head of the bolt 5) to be screwed into the bolt 5 is buried, and a seat hole 6D into which a wooden plug 7B is fitted is provided. As shown in FIG. 4 (B), the mutual connecting portions of the horizontal rails 2 may be formed so that both ends are formed in a stepped shape and are connected alternately.

The top tree 3 has an integral multiple, for example, twice as long as the spacing between the columns 1, as in the case of the cross bar 2, and a groove 8 having a rectangular cross section is formed on the lower surface thereof over the entire length in the longitudinal direction. It is provided. On the other hand, a plug 9 is formed at the upper end of each column 1 to fit tightly into the groove 8 of the top block 3. The upper surface and the lower surface of the top tree 3 are shaped to bulge in an arc shape.

The ends of the top trees 3 are connected to each other by a joint plate 10 at the column 1. This joint plate 10
A wood screw 11 is attached to the upper end of the plug 9 of the column 1
