[Free Fence]
<1> Overall configuration (Fig. 1)
The flexible fence 1 of the present invention is a fence that can be installed along the slope of the ground or the bend of the boundary.
In this example, an example in which the free fence 1 is used as a fence to prevent wild boars, deer, and other animals from harm will be described, but the application is not limited to this, and can be used for various other applications.
The flexible fence 1 includes at least a plurality of anchor posts 10 and fence panels 20 extending between the anchor posts 10. - 特許庁In this example, a stay material 30 is further provided.
One feature of the flexible fence 1 is a structure in which the fence panel 20 can be rotated around the long axis of the anchor post 10 and slidable along the long axis.

<2> Anchor post The anchor post 10 is a post that supports the fence panel 20 .
The anchor strut 10 is made of a rod-shaped body with a circular cross section, and includes at least a linear strut body 11 and a locking end 12 provided at the head of the strut body 11 .
In this example, the locking end 12 has an inverted U-shaped hook shape formed by folding back the head portion of the support body 11 .
However, the structure of the locking end 12 is not limited to this, and may be, for example, an inverted L shape, an inverted T shape, or a stud head shape. The point is that the structure can fix the height of the fence panel 20 by pressing the loop end 22a from above by driving.

<3> Fence Surface Material The fence surface material 20 is a surface material having a shielding function.
The fence surface material 20 is made of a welded wire mesh in which a plurality of vertical wires 21 and a plurality of horizontal wires 22 are assembled in a grid.
The mesh of the fence panel 20 can be appropriately selected depending on the application. In this example, the mesh of the fence surface material 20 is vertically elongated to provide a structure that makes it difficult for small animals such as raccoons and palm civets to crawl up.
The lower ends of the vertical wires 21 protrude downward from the lowermost row of horizontal wires 22 to constitute a penetration end 21a for penetrating into the ground.
Both ends of the horizontal wire 22 constitute loop ends 22a for connecting with the anchor post 10 .

<3.1> Loop end (Fig. 2)
The loop end 22 a is the portion that connects the fence panel 20 to the anchor post 10 .
The loop end 22a is formed by folding both ends of the horizontal wire rod 22 into a U shape when viewed from above.
A communication path is defined in loop ends 22a of a plurality of horizontal wires 22 arranged vertically in parallel with each other so that the support body 11 of the anchor support 10 can be communicated with.
In this example, one longitudinal wire 21 connects the folded ends of the loop ends 22a.
Since both ends of the horizontal wire 22 are not ring-shaped structures but loop ends 22a folded back, for example, when a vermin collides with the fence panel 20, the loop ends 22a are elastically deformed to open and absorb the impact. Thus, it is possible to prevent the anchor strut 10 from being deformed or tilted due to transmission of impact to the anchor strut 10 .
In addition, by connecting the tip of the loop end 22a with the vertical wire 21, even if the loop end 22a is momentarily opened at the time of impact, the vertical wire 21 on the loop end 22a of the adjacent fence panel 20 is on the impact receiving side. By suppressing the loop end 22a of the fence panel 20 from the outside, it is possible to prevent the fence panel 20 from detaching from the anchor post 10. - 特許庁

<4> Stay Material The stay material 30 is a member that reinforces the fence panel 20 .
In this example, a long metal anchor whose head is folded back like a hook is used as the stay member 30 .
The hook of the head of the stay member 30 is locked near the center of the fence panel 20, and the tip is driven into the ground to connect the fence panel 20 and the ground, and the fence panel 20 is oriented perpendicular to the plane. to reinforce.
It is effective to arrange the stay material 30 on the vermin side of the fence panel 20, but it is more preferable to arrange it on both sides of the fence panel 20 in the plane direction.
The stay member 30 is not limited to a metal anchor, and may be another rod-shaped body or a cord-shaped body such as a wire rope that connects the fence panel 20 and the ground.

<5> Fence structure (Fig. 3)
The fence structure A is a structure in which a plurality of flexible fences 1 are continuously installed on the ground.
The fence structure A is installed, for example, in the following procedure.
The fence panel 20 is installed at an installation place, and the lower penetrating end 21a is inserted into the ground and fixed.
Subsequently, the post main body 11 of the anchor post 10 is communicated with the inside of the loop end 22a of the fence panel 20, and the lower end is driven into the ground. Here, in the flexible fences 1 other than the flexible fence 1 at the extreme end, two adjacent fence panels 20 share one anchor post 10. - 特許庁Therefore, the loop ends 22a of the two fence panels 20 are overlapped (FIGS. 2(a) and 2(b)), and the anchor post 10 is communicated with the overlapped loop ends 22a (FIG. 2(c)). type in.
The fence structure A of the present invention rotates the other side of the fence panel 20 around the anchor column 10 in a state in which the anchor posts 10 are driven only on one side of the fence panel 20, and the flexible fence 1 can be freely moved. Since it can be bent at any angle and extended, the degree of freedom in design is high. In addition, since the orientation of the fence panel 20 can be adjusted on site according to the conditions of the installation site, such as standing trees and unevenness of the ground, there is a high degree of freedom in construction.

<6> Installation on a slope (Fig. 4)
When installing the fence structure A along the inclination direction of the ground, the heights of two adjacent fence panels 20 are shifted up and down according to the inclination of the ground and connected to one anchor post 10. do.
In this example, as the fence panel 20, the fence panel 20 having a width of 1/4 of the fence panel 20 for flat ground is used. By using the narrow fence panel 20 in this manner, the fence structure A can be installed without difficulty even if the slope is steep.
In the fence structure A of the present invention, even if the ground has unevenness along the direction of inclination, the penetrating end 21a of the fence panel 20 is installed by penetrating the ground. There is no gap between
