Description

  The present invention relates to a column extension member that is attached to an electric fence, a welded wire mesh, or the like that is installed to prevent invasion of harmful animals.

  In recent years, with the increase in the number of wild animals such as wild boars, monkeys and deer, and changes in habitats, so-called food damage that eats crops such as fields and orchards has become a major social problem. In addition, animals invade mountains, ranches, and golf courses, causing various damage.

  Various methods have been used in the past to prevent such damage caused by harmful animals, but a bare wire is stretched around the field as a representative example, and an impact voltage is applied to the bare wire. There is an electric fence designed to do. This is because a high-voltage pulse voltage is applied to the bare wires supported by the pillars, each connected to the plus or minus electrode, and the animals touching the plus and minus poles of these bare wires are affected by electric shock. It is dissipated by feeling pain and prevents invasion.

  In addition, a method is widely used in which a net is stretched around the field or a welded wire mesh is stretched to prevent the invasion of animals.

  However, animals with high jumping power, such as deer, and animals with high climbing ability, such as monkeys, may invade fields by jumping over electric fences, nets, etc., or climbing up columns. Therefore, in order to prevent such a situation, a method has been proposed in which a return member is provided on the upper part (Patent Document 1) and a column is extended (Patent Document 2).

  The present invention also provides means for effectively preventing the invasion of animals as described above. More specifically, the present invention can be easily attached to an electric fence, a support of a welding wire mesh, or a net or the welding wire mesh itself. An object is to provide a column extension member.

  The configuration of the present invention that achieves the above object is as follows.

  (1) A column extension member according to claim 1 is provided with a base end portion provided with a hollow portion into which an insulator is fitted, an extension for obliquely extending from the base end portion, and a hook for a bare electric wire or a net. And a branch portion having a stop portion.

  (2) The column extension member according to claim 2 is the invention according to claim 1, wherein a hook for hooking to a welded wire mesh or a net is provided at the upper part of the base end portion and a groove portion is provided in the vertical direction. did.

  (3) In the invention described in claim 1 or 2, the column extending member according to claim 3 is configured by providing a hole 25 at a portion where the branch portion 30 extends from the base end portion 20.

  Hereinafter, how the present invention configured as described above works to solve the problem will be described with reference to the drawings.

  2 is a rear view of the present invention, and FIG. 5 is a bottom view. In the column extending member according to the present invention, a cavity portion 21 is provided on the back side of the base end portion 20. 7 and 8 are explanatory views showing a process of attaching the column extension member 10 according to the present invention to the insulator 2 provided on the column 1, and as shown in the figure, the insulator 2 of the electric fence post 1 is attached. The support column 1 can be extended by being fitted in the hollow portion 21.

  FIG. 9 shows a state in which the column extending member according to the present invention is attached to the welded wire mesh 4 constituting the animal net. As shown in FIG. 10, the hook 23 is hooked to the horizontal bar 4a constituting the mesh of the welded wire mesh 4, and the column extending member 10 is attached to the welded wire mesh 4 by fitting the vertical bar 4b into the groove portion 22. It becomes possible.

  FIG. 11 shows a state in which the column extending member 10 according to the present invention is attached to the column 1 using the band member 4. The band member 4 is loosely inserted into the hole 25 provided in the portion where the branch portion 30 is extended, and the binding band 4 is wound around the outer peripheral surface of the base end portion 20 and the support column 1, thereby This makes it possible to attach the column extending member 10.

  As described above, according to the present invention, it is possible to extend the strut, and as shown in FIG. 9, it is possible to effectively infiltrate the animal by stretching the bare electric wire 5 on the strut extending member or stretching the net. It becomes possible to deter.

  In particular, because the branch-like portion of the column extension member is provided in an oblique direction, it feels like an overhanging bare electric wire or net is covered from the top for animals trying to invade. The deterrence effect is extremely high, and the intrusion can be deterred as much as possible.

  Hereinafter, an embodiment of a preferred invention will be outlined with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

  As shown in FIGS. 1 to 6, the column extension member 10 according to the present invention is provided integrally with the base end portion 20, which is a portion for attaching to a column or a welded wire mesh, and the base end portion 20. The branch portion 30 extends obliquely upward from the end portion 20. As the material, various resins such as a resin having high hardness such as FRP and a resin having high elasticity such as polypropylene and polyethylene can be used.

  The branch portion 30 extends obliquely upward from the front side of the base end portion 20, and a plurality of locking portions 31 are provided. As shown in FIG. 3, the locking portion 31 has a plurality of layers of rod bodies 31 a, and a curved portion 31 b is formed between the rod bodies 31 a. The curved portion is provided with a barb 31c for preventing the bare electric wire from being easily pulled out. With such a shape, it is possible to hook a bare electric wire constituting the electric fence, and it is also possible to hook a net or the like.

  The base end portion 20 has a substantially rectangular parallelepiped shape, and a hollow portion 21 is formed therein. As shown in FIGS. 2 and 5, the hollow portion 21 is open on the back side, and the open end portion is provided with a pair of locking projections 24 formed from the bottom surface to the plane and formed thick. By providing this locking projection 24, the width H of the open end becomes narrower than the width of the cavity 21, and the base end 20 and the lever are locked by such a shape, and the column extending member 10 is from the lever provided on the column. This prevents it from coming off.

  A groove portion 22 is formed in the cavity portion 21 by providing a partition wall 26. As shown in FIG. 4, the groove portion 22 reaches the upper end of the base end portion 20 and is configured to have a shape in which the upper end is opened.

  A pair of hooks 23 are provided on the upper portion of the base end portion 20. The pair is formed because the groove 22 is divided up to the upper end edge.

  As shown in FIG. 3, a pair of hole portions 25 is provided on the back surface side of the base end portion 20, at a portion where the branch-like portion 30 extends. A band member such as a binding band, a wire, a U-bolt, or the like is loosely inserted into the hole 25, and is fastened and fixed to the column.
