[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence corner connecting device used for connecting a corner portion between a fence body and a fence body. (Prior Art) Conventionally, there is a device shown in FIG. 10 as a device for connecting the corner portions of a fence body provided on, for example, a flat land and a sloping ground. The connecting device in the figure is a furring strip 1 that constitutes one fence body.
00 is fixed to the end portion of the first connecting member 101, and the second connecting member 103 is fixed to the end portion of the furring strip 102 constituting the other fence body. The first and second connecting tools 10
Reference numerals 1 and 103 denote semicircular projections 101 having a tip semicircular shape in a relative positional relationship with each other on approximately one half of the fence body on one side in the inward and outward directions.
a, 103a. The above-mentioned connecting device is constructed by combining the two protrusions 101a and 103a.
By screwing a screw 104 on a, both furring edges 101,
102 and both fence bodies are connected, and the connection angle of the other furring strip 102 with respect to one furring strip 100 can be vertically adjusted around the screw 104 in accordance with the angle of the sloping ground with respect to the flat ground. . (Problems to be Solved by the Invention) However, the conventional coupling device as described above is not suitable for each furring strip 1
No. 01, 102 only constitutes a pivotally connected portion by the screw 104. For example, as a load that is easily applied to the fence, it depends on the strength of the screw 104 itself with respect to the force from the vertical direction and the direction inside and outside the site. Since it is a structure, it cannot be said that the strength as a corner part is sufficient, and it becomes necessary to separately support the corner ends of both fences with columns in order to secure the strength, resulting in work man-hours and cost. However, there is a problem that it is not preferable, and it has been a problem to solve these problems. (Purpose of the Invention) The present invention has been made to solve such a conventional problem. It is possible to adjust the angle in the vertical direction and improve the strength against the force from the vertical direction and the inside / outside direction of the site. It is an object of the present invention to provide a fence corner connecting device that can realize the reduction in the number of columns and the like as the strength is improved.

[Constitution of device]

(Means for Solving the Problems) A fence corner connecting device according to the present invention includes a first connecting member having a mounting portion for one fence body and a second connecting member having a mounting portion for another fence body. A pivoting portion is provided so that the pivoting portions are pivotally attached to each other by a horizontal axis orthogonal to the longitudinal direction of the fence body, and the horizontal axis is centered on a portion of the first connecting tool facing the second connecting tool. As a convex portion extending substantially in a fan shape over a predetermined angle range, a concave portion into which the convex portion rotatably enters is provided at a portion of the second coupling tool facing the first coupling tool. This configuration solves the conventional problem by adopting a configuration in which the opening edge portion intersects the vertical direction of the horizontal axis and is inclined along an imaginary line that is inclined in a direction opposite to the first coupling tool. As a means to (Effect of the Invention) In the fence corner connecting device according to the present invention, the first and second connecting members attached to each fence body are rotatably connected by the horizontal shaft provided in the pivotal portion, and at this time, the convex portion is By advancing into the concave portion, in addition to the connection state by the horizontal axis, the convex portion and the concave portion are engaged with each other, and the strength of the fence against the force from the vertical direction and the inside / outside direction of the site is improved. In addition, the corner connecting device of the fence,
In order to prevent rotation restriction by the convex portion and the concave portion, the opening edge portion of the concave portion is in the above inclined state. Thereby, the second connector is, for example, with respect to the horizontally provided first connector,
