[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a rim of a fence or the like and a column which can freely adjust the angle in a horizontal direction and a vertical direction.

[0002]

2. Description of the Related Art Conventionally, when an angle is changed in the horizontal direction when a fence, a fence or the like is stretched, or when an inclination angle such as a slope is required, the end of the body edge is attached to the column side of the plate. The end face to be contacted was processed according to the angle.

[0003]

The conventional connection structure between the rim and the column, which requires an angle in the horizontal or vertical direction, is as follows.
It was necessary to prepare many types of mounting plates according to the angle, or to process the mounting plate in accordance with the angle change at the site, which had the drawback that the workability was poor and the cost was high.

In order to solve the above problems, according to the present invention, it is possible to attach a connecting portion of a body edge to a column at an arbitrary angle in the vertical and horizontal directions without changing or processing the connecting portion for each angle. It is another object of the present invention to provide a connecting structure between a rim and a pillar that can improve cost.

[0005]

In order to solve the above-mentioned problems, the connecting structure according to the present invention comprises a pair of cylindrical bodies having one end face abutting on the support with the support interposed therebetween, and the other end of the cylindrical body having an end of the body edge. The heads of the hollow mounting caps for inserting and holding are slidably fitted, respectively, and a bolt through hole is formed in the head of the mounting cap, and a washer is provided in the bolt through hole. The pair of cylindrical bodies and the mounting cap, which are slidably fitted from the inside, are connected by bolts and nuts through washers, and the fitting surface of the outer head of the mounting cap and the cylindrical body. The inner fitting surface, the outer fitting surface of the washer, and the inner fitting surface of the bolt insertion hole are each formed as a concentric spherical surface.

[0006]

In order to explain the operation of the connecting structure of the present invention, the head of one of the mounting caps sandwiching the column is fitted into the rear end of the cylindrical body, and then a washer is inserted into the bolt hole from the rear end of the mounting cap. At the same time, the bolt is inserted into the washer, and the forward end is protruded from the head and the cylindrical body of the cap, and the tip of the bolt is inserted into the bolt insertion hole of the column. And
The cylindrical body is abutted on the column, and the forward end of the bolt is projected out of the column through the bolt insertion hole on the opposite side of the column.

Then, the front end of the other cylindrical body having the head of the mounting cap fitted to the rear end thereof is abutted to the opposing portion with the column interposed therebetween, and the forward end of the bolt is attached to the other cylindrical body and the mounting cap. Protrude into the mounting cap from the bolt insertion hole, insert the washer through the protruding tip of the bolt, insert the washer into the bolt insertion hole, and tighten it with the nut from the end of the bolt. And both cylindrical bodies are also fixed to the column.

When the angle is set in the horizontal direction or the vertical direction, the mounting cap is grasped and turned to the set angle, so that the outer fitting surface of the head is fitted to the inner fitting surface of the cylindrical body. It is slidably fitted, the outer fitting surface of the washer is slidably fitted on the inner fitting surface of the bolt hole of the mounting cap, and these fitting surfaces are all formed as concentric spherical surfaces. As a result, the mounting cap rotates in any direction, up, down, left, and right. Therefore, the mounting cap is turned at the set angle, the body edge is inserted from the rear end of the mounting cap, and the body edge is fastened to the mounting cap with the fastening bolt.

Although the operation of the present invention has been described above, when a bolt is inserted into a column, even if the bolt insertion hole of the column is not shifted horizontally but drilled in a position shifted so as to be inclined. Since the washer slides freely on the inner fitting surface of the bolt insertion hole of the mounting cap, the bolt can be obliquely inserted into the column without the mounting cap being horizontal and in line with the bolt.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal sectional front view of an embodiment of the present invention; FIG. 2 is a partially exploded perspective view of the same; 3 to 4 are front views showing a use state, and FIG. 5 is a plan view showing a use state.

In the drawings, reference numeral 1 denotes a column, 2 denotes a bolt insertion hole formed in the column 1, and 3 denotes a pair of left and right cylindrical members which abut on the position of the bolt insertion hole 2 of the column 1. The front end of the cylindrical body 3 that contacts the column 1 is formed in an arc shape so as to conform to the side surface shape of the column 1, and the rear end is an inwardly concave arcuate fitting surface 3.
A is formed. Reference numeral 4 denotes a cylindrical mounting cap, and a bolt insertion hole 5 is provided at the center of the head of the mounting cap. An arc-shaped fitting surface 5A dented toward the inside of the mounting cap 4 on the inner surface of the bolt insertion hole 5
Are formed. And the head 4 of the mounting cap
The outer fitting surface 4B of A is formed in a spherical arc concentric with the fitting surface 3A of the tubular body 3 so as to be slidably fitted into the fitting surface 3A of the tubular body 3. Further, the mounting cap 4 is formed so that one surface 4C of the body can be separated. Reference numeral 6 denotes a bolt hole formed in the body of the mounting cap 4.

Reference numeral 7 denotes a washer which is slidably fitted into the fitting surface 5A of the bolt insertion hole 5, and an outer fitting surface 7A of the washer 7.
Is formed in a spherical arc concentric with the fitting surface 5A of the bolt insertion hole 5. Reference numeral 8 denotes a bolt that penetrates through the cylindrical body 3 and the column 1 from inside one of the mounting caps 4 and passes through the cylindrical body 3 at the opposing portion and into the mounting cap 4. Reference numeral 9 denotes a nut of the bolt 8. Reference numeral 10 denotes a body edge, an end of which is inserted into the mounting cap 4 and fastened with a fastening bolt 11.

[0013]

According to the present invention, since the mounting cap slides in all directions as well as in the vertical and horizontal directions, the mounting cap can be mounted at an arbitrary angle, for example, when the direction is changed on an inclined or flat ground. Further, unlike the related art, there is no need for machining work on site, so that the workability is good, and since there is no need to change the mounting fixture every time the angle is changed, the cost is low and the invention is useful.
