Modes for Carrying Out the Invention

[0017] An anti-animal net according to an embodiment of the present invention will be described with reference to the drawings. N shown in FIG. 1 is an anti-animal net used at the site of agricultural management, etc., and is, for example, a net suitable for medium-sized animals such as badgers, raccoon dogs, tanukis, Japanese martens, weasels, moles, Siberian weasels, and wild boars such as wild boars.​ The anti-animal net N is a net that is erected on the ground G and has a netting, and is used to prevent animals from entering. It has a first net 1, a second net 2, and a third net 3 from bottom to top. The anti-animal net N supplies current from a power source (not shown) to the conductive member 4 to prevent animals from entering the anti-animal net N.

[0018] The first net 1 shown in Fig. 1 is deformed (bent and deformed) corresponding to the unevenness of the ground G to close the gap with the ground G, or, although not shown, is deformed corresponding to the unevenness of the ground G, abuts on the ground G, and soil 100 (in Fig. 1, the soil 100 in Fig. 2 is omitted, but as in Fig. 1, the soil 100 may be omitted, but preferably, as in Fig. 2, the soil 100 may be piled on the first net 1 abutting on the ground G.) is piled on the first net 1 abutting on the ground G, and at least the connection part between the first net 1 and the second net 2 is covered with the soil. The first net 1 is, for example, a Russell net, and the material of its netting is formed of polyester, nylon, etc. The reason why the soil 100 is piled on the first net 1 abutting on the ground G is that animals such as raccoon dogs and badgers have the habit of digging holes, and when they dig a hole and hit an obstacle (in this embodiment, the first net 1) in the ground G, it utilizes the habit of stopping digging holes.

[0019] Also, the second net 2 is a harder net than the first net 1. As shown in Figs. 1 and 2, it is erected on the ground G, or is a harder net than the first net 1 so as not to be bitten by the above animals, and is erected on the ground G, or is a harder net than the first net 1 so that the second net 2 can stand on its own, and is erected on the ground G. The second net 2 is a hard net using a fused thread as the main part, and is, for example, a product named Bellcouple (registered trademark) manufactured by KB Seiren Co., Ltd. The second net 2 is a net that is harder than the first net 1 and is erected with respect to the ground G, that is, the second net 2 is harder than the first net 1 and can stand independently, with less deformation (or less aging) in the natural environment such as seasons and weather. Animals such as badgers, raccoons, tanukis, anagumas, tengus, and wild boars recognize the erected second net 2 as a wall surface, that is, they create a surface with respect to the space. Therefore, the above animals explore the boundary with the space above the net with their snouts and forelimbs. Due to this exploration behavior, they touch the wire part above the third net 3 and get electrocuted. At this time, since the above animals place their forelimbs on the net, in order to surely lead to electrocution, it is desirable that the height is maintained without deforming even under the pressure of the forelimbs or snouts.

[0020] Also, the third net 3 is softer than the second net 2 and holds the conductive member 4 of the electric fence at least from one side of the mesh to the other side and from the other side to the one side, and the conductive member (bare wire, wire, etc.) 4 of the electric fence is held by the third net 3. The third net 3 is, for example, a Russell net, and the material of its mesh is formed of polyester, nylon, etc. In order to enhance self - standing, fused yarn may be mixed. Note that 10 shown in FIG. 2 is inside the animal - proof net N, and 20 is outside the animal - proof net N. Also, the above - mentioned electric fence has a weak current that is controlled by a power supply device (not shown) so as not to cause electrocution flowing through the conductive member (bare wire, wire, etc.) 4 to give a shock. With the electric fence, it is possible to prevent animals such as badgers, raccoons, tanukis, anagumas, tengus, snow rabbits, Siberian weasels, and wild boars from entering the animal - proof net N with a mild electric shock.

[0021] Therefore, according to the above-mentioned anti-animal net N, when an animal approaches the net or tries to dig the ground directly under the net with the first net 1, it will entangle the animal's feet to prevent intrusion, or since soil 100 is piled on the first net 1 in contact with the ground G, animals such as badgers, raccoon dogs, etc. will prioritize the action of digging holes to invade, so there is a physical and psychological anti-intrusion effect as an obstacle directly under the net. Moreover, the second net 2 is a net harder than the first net 1 and is erected with respect to the ground G, that is, the second net 2 is harder than the first net 1 and can stand independently, with less deformation (or less aging change) in the natural environment such as seasons and weather. Animals such as wild boars, bears, raccoon dogs, badgers, monkeys, and wild boars will recognize the erected second net 2 as a wall surface, that is, it will form a surface with respect to the space. Therefore, the above animals will explore the boundary with the space above the net with their snouts and front legs. Due to this exploration behavior, they will touch the conducting wire part above the third net 3 and get an electric shock. At this time, in order to surely lead to an electric shock because the above animals place their front legs on the net, it is desirable that the height is maintained without deforming even under the pressure of the front legs or snouts. Furthermore, if an animal tries to stand up and climb over the net, it will touch the conductive member 4 of the electric fence and get an electric shock, and the animal can be kept away from the anti-animal net N. The third net 3 is softer than the second net 2, and the conductive member 4 of the electric fence can be easily held on the third net 3 by passing the conductive member 4 at least from one side of the mesh to the other side and from the other side to the one side.

[0022] The animal is any one of wild boars, bears, raccoon dogs, badgers, monkeys, snow monkeys, Siberian weasels, wild boars, etc. When the upper end of the third net 3 is at a position 30 cm to 45 cm from the ground G in the case of Honshu (50 cm to 65 cm from the ground G in the case of Hokkaido), since the height of the anti-animal net N is low, a person can step over the anti-animal net N and enter the anti-animal net N. H is the height from the ground G to the upper end of the third net 3.

[0023] In addition, the first net 1, the second net 2, and the third net 3 are integrally sewn with, for example, a synthetic resin. If the second net 2 is a net knitted with a core-sheath type heat-sealing yarn, the animal-proof net N can be easily manufactured. In addition to the core-sheath type heat-sealing yarn made of a core-sheath type composite fiber in which the core has a high melting point and the sheath has a low melting point, there are side-by-side type heat-sealing yarns, heat-sealing yarns obtained by interweaving, twisting, combining, or blending a synthetic fiber having a low melting point with a synthetic fiber or natural fiber having a high melting point. Specific examples of these heat-sealing yarns include, for example, Bellcouple (registered trademark, manufactured by Kanebo Ltd., type LHC, filament, core: polyester, sheath: low melting point copolyester), Bellcouple (registered trademark, manufactured by Kanebo Ltd., type HCC, filament, core: polyester, sheath: nylon), Bellcouple (registered trademark, manufactured by Kanebo Ltd., type LCO, core: polyester, sheath: low melting point copolyester), etc. core-sheath type heat-sealing yarns; core-sheath type heat-sealing yarns for core-sheath type blended yarns such as Belcombi (registered trademark, manufactured by Kanebo Ltd., staple, core: polyester, sheath: low melting point polyester or polyethylene); staple heat-sealing yarns such as type PP-HB (manufactured by Chisso Corporation, propylene homopolymer, staple), type BF (manufactured by Daiwa Spinning Co., Ltd., ethylene homopolymer, staple), type 410 (manufactured by Eastman, copolyester, staple); side-by-side type heat-sealing yarns such as type ES (manufactured by Chisso Corporation, one side: polypropylene, the other side: polyethylene), etc. These can be used alone or in combination of two or more. In this embodiment, the core-sheath type heat-sealing yarn is not limited to a crystalline polymer, and can be similarly applied to the amorphous polymer described in JP-A-2018-150667.

[0024] In the case of the animal-proof net N shown in FIGS. 1 to 3, the third net 3 is softer than the second net 2, and the conductive member 4 is passed from one side of the mesh of the animal-proof net N to the other side and from the other side to the one side, and the conductive member 4 is held by the third net 3. However, the present invention is not limited to this. As shown in FIG. 4, the third net 3 may be formed of a conductive member, and a current from a power source (not shown) may be supplied to the third net 3 formed of the conductive member via the conductive member 4' to prevent animals from entering the animal-proof net N.

[0025] Also, in the case of the animal-proof net N shown in FIGS. 1 to 4, the third net 3 is provided. However, the present invention is not limited to this. As shown in FIGS. 5 and 6, the upper ends of the second nets 2 may be connected by a connecting member 5. The second net 2 holds the conductive member 4 at least by passing the conductive member 4 from one side of the mesh to the other side and from the other side to the one side. The conductive member 4 is held by the second net 2, and a current from a power source (not shown) may be supplied to the conductive member 4 to prevent the small animals from entering. In this case, the height from the ground G to the upper end of the second net 2 is preferably at a position of 30 cm to 45 cm from the ground G in the case of Honshu, and at a position of 50 cm to 65 cm from the ground G in the case of Hokkaido.

[0026] Also, as shown in FIG. 1, an intermediate conductive member 42 is provided on the second net 2 separately from the conductive member 4. The intermediate conductive member 42 is provided between the ground G and the conductive member 4 and is provided along the ground G. This is to prevent a young animal from standing up and touching the intermediate conductive member 42 through which the electricity of the animal-proof net N is flowing. In this case, the height from the ground G to the intermediate conductive member 42 is preferably at a position of 10 cm to 25 cm from the ground G in the case of Honshu, and at a position of 30 cm to 45 cm from the ground G in the case of Hokkaido.

[0027] Incidentally, as for the anti-animal net N described above, it is recommended to use the product named "Katamattakun" manufactured by Nakada Sangyo Co., Ltd., which is woven by integrating the first net 1, the second net 2, and the third net 3. Also, the color of the third net 3 in Fig. 1 (for example, white) may be made different from the color of the second net 2 (for example, black).
