BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an animal invasion prevention fence according to an embodiment of the present invention will be described in detail with reference to the drawings.

First, an animal intrusion prevention fence 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view of a state where a sheet of the animal intrusion prevention fence 1 and a part of a wire mesh are removed, and FIG. 2 is a side view of the animal invasion prevention fence 1.

The animal invasion prevention fence 1 is an animal invasion prevention fence for animals such as monkeys, and is continuous along the entire circumference of the area where it is desired to prevent the invasion of the animal or along the line which prevents the passage of the animal. Will be placed in the As shown in FIG. 1, the animal intrusion prevention fence 1 includes a support column 2 standing on the ground at predetermined intervals (for example, 1 to 5 m) along the entire circumference of the region or the above line, and the support column 2. The wire netting 4 is supported by the wire netting 4 and extends upward from the ground, and the seat 6 is supported by the pillar 2 and extends upward from the upper end of the wire netting 4.

The pillar 2 is made of metal such as steel, and its lower end is used for fixing a concrete foundation 8 buried in the ground, like conventional fence pillars and pasture fence pillars. It is inserted and fixed in the hole 8a, and is arranged so as to extend substantially vertically from the ground upward. The lower part of the animal intrusion prevention fence 1 is formed of a wire mesh that allows the wind to pass therethrough, so that the foundation 8 is more difficult than a fence formed of a wall that blocks the wind.
The structure and construction of can be simple.

An extension member 10 is connected to the upper end of the column 2. This extension member 10 is attached to the upper end of the support column 2 by a fixing means such as a bolt so as to extend obliquely upward in the direction of entry of the target animal, that is, outside the area surrounded by the animal intrusion prevention fence 1. Has been.

The middle portion and the upper end portion of each column 2 are connected by a lower horizontal connecting member 12 and an upper horizontal connecting member 14, which extend substantially horizontally. These connecting members 12, 14
Is a rod-shaped member formed of a metal material such as steel, and is fixed to the column 2 by a fastener such as a bolt or welding. The height position of the lower lateral connecting member 12 is the height position of the upper end of the wire netting 4. A wire 16 is connected to the upper end of each extension member 10. Wire 16
For example, the annular member 1 attached to the upper end of the extension member 10.
By being inserted in 8, the extension members 10 are connected to the upper ends thereof.

The upper end of the wire mesh 4 is a lower horizontal connecting member 12
It is arranged so as to extend upward from the ground by being fixed to the support column 2 with a wire or a mounting metal fitting, and the portion overlapping the support column 2 is supported by the support column 2 and the lower lateral connecting member 12. There is. The lower end of the wire netting 4 is fixed to the ground by an anchor member 20 arranged at an interval narrower than the interval between the columns 2 so that the wire net 4 does not turn up.

In the present embodiment, the mesh of the wire net 4 is in the shape of a turtle shell, and the monkey cannot pass through the mesh, but is sized to allow small animals such as rats and snakes to pass through.

The seat 6 is arranged between the wire 16 connecting the upper end of the extension member 10 and the lower lateral connecting member 12. Therefore, the sheet 6 is arranged so as to extend upward from the upper end of the wire net 4. As mentioned above,
Since the extension member 10 extends so as to be inclined outward, the seat 6 is also inclined outward. The inclination angle of the wall sheet 6 is appropriately selected between about 5 and 45 degrees according to the type of target animal, and in the present embodiment, about 5 to 3 degrees.
0 degree is preferable, and about 10 to 15 degree is more preferable.

At the upper end of the sheet 6, holes 6a reinforced with eyelets are formed at predetermined intervals. Fixed rope 22
Through the hole 6a and the upper side of the wire 10,
The upper end of the sheet 6 is connected to the wire 10 in a state of being suspended from the wire 10 by continuing to place the sheet 6 through the adjacent holes 6 a. Further, the lower end of the sheet 6 is folded back to be processed into a loop (bag) portion 6b, and the lower lateral connecting member 12 is passed through the loop portion 6b. Further, the attachment 24 penetrates the seat 6 from the outside of the loop portion 6b and is attached to the lower horizontal connecting member 12, and the lower end of the seat 6 is fixed to the lower horizontal connecting member 12.

The sheet 6 is made of, for example, polyester fabric,
It is made of a canvas sheet made of vinyl chloride, EVA, vinyl acetate, or the like. In addition, the sheet 6 preferably has a strength of TH-5000 class so that the monkey does not break even if it touches the nail. At least the surface of the sheet 6 in the monkey intrusion direction (outside) is smooth, and there is no clue such as a protrusion or a hole with which the monkey can reach.

The height (vertical length) of the seat 6 is set to about 120 cm or more so that even if a monkey climbing up to the uppermost portion of the wire net 4 jumps, the upper edge of the seat 6 cannot be touched. .

Further, the upper edge of the seat 6 is arranged at a height position such that even if a monkey jumps up from the ground, the upper edge cannot be touched, for example, a position about 300 to 350 cm from the ground. .

According to the first embodiment configured as described above, even if the monkey tries to pass through the mesh of the wire net 4, the mesh size of the wire net 4 is smaller than that of the monkey.
You cannot pass through. Further, even if the monkey climbs on the wire net 4, the monkey 6 cannot climb above the wire net 4 because the monkey 6 has a smooth surface on which the monkey 6 does not reach. Further, even if the monkey climbing up on the wire net 4 tries to reach the upper edge of the wall sheet 6 or jumps to the upper edge, the sheet 6 has a predetermined height.
The monkey cannot reach the upper edge of the seat 6. Further, even if the monkey tries to jump from the ground to the upper edge of the seat 6, the upper edge of the seat 6 is located at a height position where the monkey cannot get over, so that the monkey cannot get over the fence. In this way, the invasion (passage) of the monkey can be prevented.

With such a structure, the invasion of monkeys and the like can be effectively prevented without using electricity. Therefore, the Ministry of International Trade and Industry (now the Ministry of Economy, Trade and Industry) Ordinance 74 (prohibition of facilities for electric fences)
According to the regulations, it can be installed around houses and urban areas where the installation of electric fences is prohibited.

In this embodiment, the wire mesh 4 and the sheet 6 which are relatively lightweight materials are used, and since the wire mesh 4 is not subjected to the force of wind, the foundation 12 for fixing the support 2 is simplified. Can be realized. Also, sheet 6
Is inclined toward the invading direction of the monkey, so that it is difficult for the monkey to climb and the force of the wind received by the animal invasion prevention fence 1 can be weakened.

Furthermore, since the lower portion has a mesh size that allows passage of small animals such as mice and snakes although monkeys cannot pass through, the small animals are protected from animal invasion fence 1.
It is possible to freely cross the road and maintain the ecosystem of the facility.

The sheet 6 may be composed of a plurality of sheet materials that are longitudinally butted at the support columns 2 or a plurality of sheet materials that are laterally butted at a predetermined height position. good. In this case, the workability of the laying work is improved, and the work can be performed relatively easily even when the facility is installed on a slope.

In the above embodiment, the sheet 6 is used as the wall means.
However, a plate member may be used instead of the sheet. As the plate member, various plates such as a resin plate such as FRP, a metal plate, and a wooden plate are used. When the plate member is used as described above, the strength is increased and the durability is improved as compared with the sheet 6.

Next, with reference to FIG. 2, an animal intrusion prevention fence 30 according to a second embodiment of the present invention will be described. FIG. 2 is a front view of the animal invasion prevention fence 30.

The animal invasion preventive fence 30 has basically the same structure as the animal invasion preventive fence 1 of the first embodiment. Therefore, the same parts as those in the first embodiment are designated by the reference numerals, and the description thereof will be omitted.

As shown in FIG. 2, a plurality of belt-shaped electrodes 32 extending in the lateral direction are provided on the front side (the monkey intrusion side) of the sheet 6. In the present embodiment, the belt-shaped electrode 32 is a stainless steel plate. The belt-shaped electrode 32 is attached on the sheet 6 so as not to form the unevenness which becomes a clue of the monkey. 1 for each electrode plate 32
A power source 34 such as a 2V battery is connected via an electric wire 36. A current may be passed through the electrode plate 32 all the time, or a current may be passed intermittently. In the latter case, the electrode plate 32 and the power source 34 are connected via an appropriate control device.

According to this structure, when the monkey climbs up the wire netting 4 and puts his or her hand on any of the electrode plates 32, a current flows between the monkey and the grounded wire netting 4, and the monkey is electrically connected. Receive a shock.
