Description

The present invention relates to an animal invasion prevention fence for preventing the invasion of animals, a method for constructing the animal invasion prevention fence, and an animal invasion prevention method using the animal invasion prevention fence.

Fences (animal invasion) on the ground along the boundary of the areas where you want to prevent animal invasion (animal invasion prevention area) in order to prevent animal damage such as agricultural products being devoured by wild animals and human beings being attacked by wild animals. Prevention fences) are being installed. As the animal invasion prevention fence 10 of this kind, as shown in FIG. 7, a fence having only a wire mesh erected on the ground can be mentioned. However, the animal invasion prevention fence 10 in which only the wire mesh is installed cannot prevent the invasion of animals. This is because ferocious animals such as ingots and clever animals, even if there is an animal invasion prevention fence 10, can crush the animal invasion prevention fence 10 and destroy the animal invasion prevention fence 10 or the ground below the animal invasion prevention fence 10. This is because they try to break through the animal invasion prevention fence 10 by digging up and sneaking through the animal invasion prevention fence 10.

In this regard, in Patent Document 1, as shown in FIG. 1 of the same document, the fence main body 1 is tilted upward from the front side to the back side with respect to the ground, and the fence main body 1 is tilted. The fence main body 1 and the fence support 2 have a plurality of vertical wires 4 spaced in the left-right direction and a plurality of horizontal wires 5 spaced in the front-rear direction. An animal invasion prevention fence (animal invasion prevention fence) formed from a wire mesh 3 fixed in a grid pattern has been proposed.

In Patent Document 1, beasts such as deer, ingots, and foxes have a habit of disliking foreign matter from touching their feet (paragraph 0036 of the same document). When the main body 1 is arranged at an angle to invade fields, pastures, etc., as shown in FIG. 3 of the same document, the feet are in a state of entering the portion near the rear end of the fence main body 1 ( Paragraph 0035) of the same document, it is stated that the invasion of beasts into fields, rangelands, etc. can be effectively prevented.

JP-A-2017-042081

However, the animal invasion prevention fence of Patent Document 1 is formed by bending one wire mesh 3, the fence main body 1 is on the front side of the bending position of the wire mesh 3, and the fence is on the back side of the bending position of the wire mesh 3. It serves as a support portion 2 (claim 1 of the same document). In other words, the fence main body 1 and the fence support 2 have an integrally continuous shape. Therefore, the animal invasion prevention fence of Patent Document 1 is a fence main body 1 (a part that gives a sense of discomfort to the feet of an animal trying to invade) depending on the environment in which it is installed, the type of animal to prevent invasion, and the like. ) Could not be adjusted in the inclination angle and length (the length along the horizontal direction from the bent position of the wire mesh 3 to the edge on the front side of the fence main body 1). In addition, the animal invasion prevention fence of Patent Document 1 cannot function as an animal invasion prevention fence because when a wild boar or the like lifts the front edge of the fence main body 1 with the tip of the nose, the entire fence rises and falls. It also had the drawback of. Further, since the animal invasion prevention fence of Patent Document 1 has a three-dimensional shape having a bent portion, it has a drawback that it is not only bulky during transportation and storage but also difficult to construct. ..

The present invention has been made to solve the above-mentioned problems, and it is possible not only to give a sense of discomfort to an animal approaching it and to discourage invasion, but also to prevent the environment in which it is installed and invasion. The present invention provides an animal invasion prevention fence capable of adjusting the inclination angle and length of a portion that gives a sense of discomfort to the feet of an animal attempting to invade, depending on the type of animal to be invaded. In addition, it is difficult for the force applied to the part that gives a sense of discomfort to the feet of the animal trying to invade to reach the whole, and even if a force in the direction of lifting is applied to the part, the form that can prevent the invasion of the animal can be maintained. It is also an object of the present invention to provide an animal invasion prevention fence. Furthermore, it is also an object of the present invention to provide an animal invasion prevention fence that is not bulky during transportation and storage and is easy to construct. Furthermore, it is also an object of the present invention to provide a method for constructing the animal invasion prevention fence and an animal invasion prevention method using the animal invasion prevention fence.

The above issues are
The first panel installation process, which installs the first panel on the ground along the boundary of the animal invasion prevention section,
A net-like second panel that is separate from the first panel is inclined so that the front side is near the ground and the back side is floating from the ground on the front side of the boundary line in the first panel. It is constructed by going through the second panel installation process,
After construction, the feet of animals approaching the first panel from the front side of the first panel to break through the first panel fit into the mesh of the second panel, or the net forming the second panel. The solution is to provide a method of constructing an animal invasion prevention fence, characterized in that the wire bites into the sole of the foot, thereby discouraging the animal from approaching the first panel.

In this way, by arranging the mesh-like second panel in a slanted position on the front side of the first panel, the feet of the animals approaching to break through the animal invasion prevention fence will fit into the mesh of the second panel. The net wire forming the second panel can be made to bite into the sole of the foot, which is a weak point of animals with hoofs. Therefore, it is possible to give a sense of discomfort to the feet of the animal, discourage the animal from invading (the willingness to break through the first panel), and achieve an excellent animal invasion prevention effect. ..

In addition, by making the second panel (the part that gives a sense of discomfort to the feet of the animal) separate from the first panel (the part that supports the second panel, etc.), the back side of the second panel with respect to the first panel By changing the support position of the edge portion, the inclination angle and length of the second panel (the length along the horizontal direction from the back edge portion to the front edge portion) can be adjusted. Therefore, it is possible to adjust the tilt angle and length of the second panel according to the environment in which it is installed, the type of animal to be prevented from invading, and the like. In addition, even if a lifting force is applied to the second panel, at least the first panel can maintain its original shape and maintain the function of preventing the invasion of animals. Further, since the first panel and the second panel can be separated and stacked, it is possible to facilitate the transportation and storage of the animal invasion prevention fence. In addition, after the flat first panel is erected on the ground, the first panel can be supported by the second panel in an inclined state, so even weak women and the elderly can install an animal invasion prevention fence. It can be easily installed.

In the method for constructing the animal invasion prevention fence of the present invention, the form of the first panel is not particularly limited as long as it can support the inner edge of the second panel. However, it is preferable to use a net-like first panel. This makes it possible not only to make the first panel excellent in visibility, but also to make it lightweight and excellent in workability. In addition, if a second panel having a hooking portion provided on the inner edge of the first panel for hooking the mesh of the first panel is used, the hooking portion is hooked on the first panel. By switching the mesh of the panel, it is possible to adjust the tilt angle of the second panel in multiple steps.

In the method for constructing the animal invasion prevention fence of the present invention, the inclination angle at which the second panel is installed is not particularly limited. However, if the front edge of the second panel is higher than the ground, it becomes easier for the animal to insert the tip of the nose or the like between the front edge of the second panel and the ground. For this reason, the front edge of the second panel should be as low as possible on the ground. Specifically, the height of the front edge of the second panel from the ground is preferably in the range of 0 to 5 cm. The height of the front edge of the second panel from the ground is more preferably 4 cm or less, further preferably 3 cm or less, and optimally 2 cm or less.

At this time, if the edge on the back side of the second panel is also at a low position near the ground, the second panel will be located along the ground (as if the second panel was placed on the ground). There is a risk that the animal whose feet are placed on the upper surface of the second panel will not feel uncomfortable. Therefore, the height of the inner edge of the second panel from the ground is preferably 10 cm or more. The height of the back edge of the second panel from the ground is more preferably 15 cm or more, and even more preferably 20 cm or more. The height of the back edge of the second panel from the ground is not particularly limited, but if it is too high, it is inevitable unless a long one is used for the second panel. In addition, the tilt angle of the second panel becomes large, which may make it difficult for animals to place their feet on the second panel. Therefore, the height of the inner edge of the second panel from the ground is usually up to about 100 cm.

In the method of constructing the animal invasion prevention fence of the present invention, it is also preferable to fix the front edge of the second panel to the ground with an anchor. Similarly, it is also preferable to fix the lower edge portion of the first panel to the ground with an anchor. This makes it possible to prevent the front edge of the second panel and the lower edge of the first panel from rising from the ground. Therefore, it becomes possible to make the animal invasion prevention fence more difficult to break through.

By the way, the above problem is
The first panel, which stands on the ground along the border of the animal invasion prevention area,
A mesh-like second panel that is separate from the first panel and is inclined so that the front side is near the ground and the back side is floating from the ground on the front side of the boundary line in the first panel. When,
Consists of
The feet of animals approaching the first panel from the front side of the first panel to break through the first panel fit into the mesh of the second panel, or the net wire material forming the second panel is the foot. It is also solved by providing an animal invasion prevention fence, which is characterized in that the animal is discouraged from approaching the first panel by digging into the back.
This animal invasion prevention fence can be suitably used in the above-mentioned construction method of the animal invasion fence of the present invention.

The above problem is also solved by providing an animal invasion prevention method for preventing the invasion of animals by using the animal invasion prevention fence of the present invention. This makes it possible to prevent even ferocious and clever animals, such as wild boars, from entering the invasion prevention target area.

As described above, according to the present invention, not only can an animal approaching it feel uncomfortable and lose its motivation to invade, but also depending on the environment in which it is installed, the type of animal to prevent invasion, and the like. It is possible to provide an animal invasion prevention fence that can adjust the inclination angle and length of the portion that gives a feeling of strangeness to the feet of the animal trying to invade. In addition, it is difficult for the force applied to the part that gives a sense of discomfort to the feet of the animal trying to invade to reach the whole, and even if a force in the direction of lifting is applied to the part, the form that can prevent the invasion of the animal can be maintained. It will also be possible to provide animal intrusion prevention fences. Further, it is possible to provide an animal invasion prevention fence that is not bulky during transportation and storage and is easy to construct. Furthermore, it is also possible to provide a method for constructing the animal invasion prevention fence and an animal invasion prevention method using the animal invasion prevention fence.

FIG. 5 is a view showing a state in which the second panel 12 is viewed from a direction perpendicular to the second panel 12.

In FIGS. 1 to 3, the x-axis, the y-axis, and the z-axis are shown for convenience of explanation. The orientations of the x-axis, y-axis, and z-axis are common in FIGS. 1 to 3. Further, in FIG. 1 and the like, the field is illustrated as a section 50 (animal invasion prevention section) for preventing the invasion of the animal 60, but the animal invasion prevention section 50 is not limited to the field, but is a garden, a road, or the like. You can also do it. Further, in FIG. 1 and the like, the wild boar is illustrated as an animal 60 that prevents invasion into the animal invasion prevention section 50, but the animal 60 is not limited to the wild boar and may be another animal such as a deer or a monkey. You can also.

As shown in FIG. 1, the animal invasion prevention fence 10 of the present invention is composed of a first panel 11 and a second panel 12 which are separate bodies (separate members) from each other. The first panel 11 is erected on the ground G along the boundary line 51 of the animal invasion prevention section 50. The first panel 11 may be a member having a continuous surface shape without an opening or the like, but in the present embodiment, a net-like plate material is used as the first panel 11. The first panel 11 is a portion that functions as a barrier that makes it difficult for the animal 60 to invade the animal invasion prevention section 50.

On the other hand, the second panel 12 is a net-like plate material arranged on the front side (negative side in the y-axis direction in FIG. 1) of the boundary line 51 of the first panel 11 with an upward inclination. The second panel 12 is arranged so as to be inclined so that the front edge thereof is near the ground G and the back edge of the second panel 12 is floating from the ground G. The second panel 12 is a portion that exerts a function of giving a sense of discomfort to the feet of the animal 60 approaching the first panel 11 in order to invade the animal invasion prevention section 50.

That is, the animal 60 attempting to invade the animal invasion prevention section 50 breaks through the first panel 11 (overcoming the first panel 11, destroying the first panel 11, or moving under the first panel 11). To dig up), the first panel 11 is approached from the front side (negative side in the y-axis direction) of the first panel 11. However, the second panel 12 is inclinedly arranged on the front side of the first panel 11. Therefore, the animal 60 approaching the first panel 11 steps on the second panel 12, and its feet fit into the mesh of the second panel 12, or the net wire rod forming the second panel 12. Will bite into the sole of the animal 60. Therefore, the animal 60 feels uncomfortable at his feet.

The animal 60, such as a wild boar, has a habit of extremely disliking the occurrence of discomfort at the feet. In this regard, as described above, the second panel 12 gives a feeling of strangeness to the feet of the animal 60 approaching the first panel 11 so that the animal 60 does not approach the first panel 11 any more. Becomes possible. In other words, it is possible to discourage the animal 60 trying to approach the first panel 11 and prevent the animal 60 from invading the animal invasion prevention compartment 50.

The inclination angle θ (FIG. 3) of the second panel 12 is not particularly limited. However, if the inclination angle θ of the second panel 12 is made too small, the second panel 12 will be placed on the ground G, and even if the animal 60 (FIG. 1) steps on the second panel 12, the feet will feel uncomfortable. It may be less likely to occur. Therefore, the inclination angle θ of the second panel 12 is usually set to 1 ° or more. The inclination angle θ of the second panel 12 is preferably 2 ° or more, and more preferably 3 ° or more.

On the other hand, if the inclination angle θ (FIG. 3) of the second panel 12 is made too large, it becomes difficult for the animal 60 (FIG. 1) to step on the second panel 12. In addition, the animal 60 (FIG. 1) may consider not only the first panel 11 but also the second panel 12 as a barrier, and may attack the second panel 12 by ramming or the like. Therefore, the inclination angle θ of the second panel 12 is usually set to 30 ° or less. The inclination angle θ of the second panel 12 is preferably 20 ° or less, and more preferably 10 ° or less. In this embodiment, the inclination angle θ of the second panel 12 is about 4 to 5 °.

As already described, the height of the front side (negative side in the y-axis direction) edge of the second panel 12 from the ground G is in the range of 0 to 5 cm, and the back side (y-axis direction) of the second panel 12 is set. The height of the edge portion (on the positive side) from the ground G is preferably in the range of 10 to 100 cm. In the present embodiment, the front edge of the second panel 12 is in contact with the ground G, and the height of the front edge of the second panel 12 from the ground G is approximately 0 cm. There is. Therefore, it is difficult for the animal 60 (FIG. 1) such as a wild boar to insert the tip of the nose or the like between the front edge of the second panel 12 and the ground G. On the other hand, the height of the back edge of the second panel 12 from the ground G is about 20 cm.

The first panel 11 and the second panel 12 are separated from each other. In the animal invasion prevention fence 10 of the present invention, the first panel 11 is mainly erected on the ground G, and then the first panel 11 is placed on the first panel 11. It is assumed that the construction is carried out through a procedure of supporting the two panels 12 in an inclined state. The back edge of the second panel 12 may adopt a structure of fixing to the first panel 11 with a bolt or the like. However, in this case, not only is the work time-consuming, but the second panel 12 is integrated with the first panel 11, and the force applied to the second panel 12 is applied to the first panel 11. There is a possibility that the first panel 11 may be turned upside down together with the second panel 12. Therefore, it is preferable that the back edge of the second panel 12 is supported in a detachable state with respect to the first panel 11.

In the present embodiment, as shown in FIG. 4, the first panel 11 is formed of a net-like plate material composed of a plurality of vertical mesh wires 11a and a plurality of horizontal mesh wires 11b. As shown in FIG. 5, a hooking portion 12c is provided on the inner edge of the second panel 12, and as shown in FIG. 3, the hooking portion 12c of the second panel 12 is provided in the lateral direction of the first panel 11. The edge of the second panel 12 on the back side is supported by the first panel 11 by hooking on the net wire rod 11b of the above. Therefore, the second panel 12 can be tilted by a simple operation of hooking the hooking portion 12c to the net wire rod 11b. Further, it is also possible to adjust the inclination angle θ of the second panel 12 by switching the mesh of the first panel 11 (the net wire rod 11b in the lateral direction) on which the hooking portion 12c is hooked. Further, it is possible to release the force applied to the second panel 12 around the hooking portion 12c and make it difficult for the force to be transmitted to the first panel 11.

The first panel 11 is erected with respect to the ground G as described above. In the present embodiment, as shown in FIG. 4, a protruding portion 11d is provided at the lower edge portion of the first panel 11, and by embedding the protruding portion 11d in the ground, the lower side of the first panel 11 is provided. The first panel 11 can be erected without a gap in the space. In the animal invasion prevention fence 10 of the present invention, the first panel 11 is a portion having a function as a barrier, but in reality, the animal 60 (FIG. 1) approaches the first panel 11 by the second panel 12. Therefore, the first panel 11 is not required to be as durable as the conventional animal invasion prevention fence. Therefore, the first panel 11 may be erected on the ground G by itself, such as by embedding the protruding portion 11d in the ground, but there is a problem that the installation stability of the first panel 11 is deteriorated. It may occur.

Therefore, in the present embodiment, as shown in FIGS. 1 and 2, support frames 20 for supporting the first panel 11 are provided at predetermined intervals to improve the installation stability of the first panel 11. If the first panels 11 adjacent to each other on the left and right have a structure in which they are connected to each other by a connecting means (cable tie or the like) which is not shown, the integrity of the adjacent first panels 11 is enhanced and the installation stability of the first panel 11 is enhanced. And durability can be increased. Further, in the present embodiment, as shown in FIG. 2, anchors 30a are driven into the lower edge portion of the first panel 11 at predetermined intervals, and the lower edge portion of the first panel 11 is fixed to the ground G. Therefore, it is possible to prevent the first panel 11 from rising from the ground G.

The anchor 30a for fixing the first panel 11 is not particularly limited, and has a simple form (for example, a peg used for installing a tent, in which the upper end portion of a linear bar has a "C" shape. It may be a bent one, etc.). However, if the anchor 30a has a simple form, the anchor 30a may come off the ground G. Therefore, in the present embodiment, as the anchor 30a, a special anchor 30 having a structure that does not easily come off when driven into the ground G as shown in FIG. 6 is used. FIG. 6 is a diagram showing an example of an anchor 30 used for fixing the first panel 11 and the like.

The anchor 30 shown in FIG. 6 is composed of an anchor main body 31 and an anchor separate body 32. The anchor body 31 includes a separate insertion portion 31a for inserting the anchor separate body 32, a movable piece portion 31b provided so as to be rotatable from both left and right sides at the lower portion of the anchor main body 31, a first panel 11, and the like. It is provided with an object holding portion 31c for holding the fixed object. On the other hand, the separate anchor body 32 is provided with ratchet portions 32a on the left and right sides of the lower portion thereof. Inside the anchor body 31, a pair of left and right gear portions (not shown) for engaging with the ratchet portion 32a are provided. The gear portion is connected to the movable piece portion 31b, and when the gear portion rotates, the movable piece portion 31b rotates in the direction of the arrow A and protrudes.

The anchor 30 fixes an object to be fixed such as the first panel 11 to the ground G in the following steps 1 and 2.
[Procedure 1]
The anchor body 31 in a state where the movable piece portion 31b is closed (a state in which the anchor body 31 does not protrude from the left and right sides) is driven into the ground. The driving work of the anchor main body 31 is performed by hitting the flat plate portion provided at the upper end portion of the anchor main body 31 with a hammer or the like. At this time, the lateral mesh wire 11b of the first panel 11 is set to fit in the object holding portion 31c of the anchor body 31.
[Procedure 2]
The anchor separate body 32 is inserted into the separate body insertion portion 31a of the anchor main body 31 that has been driven into the ground. At this time, the ratchet portion 32a meshes with the gear portion, the gear portion rotates, and the movable piece portion 31b rotates in the direction of the arrow A so as to project to the left and right in the ground. When the resistance when inserting the separate anchor body 32 is large, it is preferable to hit the flat plate portion provided at the upper end portion of the separate anchor body 32 with a hammer or the like.

In the anchor 30 driven into the ground by the above steps 1 and 2, since the movable piece portion 31b is in a state of spreading to the left and right in the ground, even if it is attempted to be pulled out upward, the resistance of the movable piece portion 31b causes it. It has a structure that cannot be easily pulled out. In the present embodiment, as described above, the edge portion on the front side of the second panel 12 is also constructed in contact with the ground G, and as shown in FIG. 2, the front side of the second panel 12 is constructed. The edge is also fixed to the ground with an anchor 30b. If the anchor 30 shown in FIG. 6 is also used for the anchor 30b for fixing the second panel 12, the front edge of the second panel 12 can be firmly fixed to the ground G. Similar to the protruding portion 11d (FIG. 4) provided on the lower edge portion of the first panel 11, the protruding portion 12d is also provided on the front edge portion of the second panel 12 as shown in FIG. The protrusion 12 can be embedded in the ground.

The material of the first panel 11 and the second panel 12 is not particularly limited as long as it has the required strength, but is usually a metal such as stainless steel. It is preferable that the surface of the metal is subjected to a rust preventive treatment such as galvanizing. Further, the net wire rods 11a and 11b (FIG. 4) of the first panel 11 and the net wire rods 12a and 12b of the second panel 12 may have a spirally twisted structure. As a result, the strength of the first panel 11 and the second panel 12 can be increased, and the durability of the animal invasion prevention fence 10 can be further increased.

The form of the first panel 11 and the second panel 12 is not particularly limited, but is usually rectangular. The opening of the first panel 11 is not particularly limited as long as the animal 60 (FIG. 1) can recognize that there is a barrier, but the opening is usually 20 to 25 cm. On the other hand, since the second panel 12 is a portion that gives a sense of discomfort to the feet of the animal 60, it is appropriately determined according to the type of the animal 60 to be prevented from invading (particularly, the size of the sole of the animal 60) and the like. To. For example, when it is desired to prevent the invasion of wild boar, the opening of the second panel 12 is usually 8 to 15 cm. In this embodiment, the opening of the second panel 12 is about 10 cm.

Further, the dimensions of the first panel 11 and the second panel 12 are also different depending on the type of animal 60 to prevent invasion and are not particularly limited. For example, assuming that the invasion of wild boar and the like is assumed, the height of the first panel 11 is preferably in the range of 100 to 150 cm, and the length of the second panel 12 (net wire in the vertical direction). The length in the direction along 12a) is preferably in the range of 100 to 150 cm. The width of the first panel 11 and the second panel 12 (the length in the direction along the net wire rods 11b and 12b in the horizontal direction) is not particularly limited, but if it is made too narrow, a large number of the first panel 11 and the second panel It becomes necessary to construct 12, and if it is made too wide, the dimensions of each of the first panel 11 and the second panel 12 become large, which may make it difficult to transport and construct. Therefore, the width of the first panel 11 and the second panel 12 is usually in the range of 100 to 300 cm, preferably in the range of 150 to 250 cm.

By the way, in the above-mentioned animal invasion prevention fence 10, the support frame 20 is installed separately from the animal invasion prevention fence 10 after the fact. Further, when the animal invasion prevention fence 10 described above is installed, the hooking portion 12c of the second panel 12 is hooked on the net wire rod 11b in the lateral direction of the first panel 11, and when the fence is removed or transported. Was supposed to remove the hooking portion 12c of the second panel 12 from the lateral mesh wire 11b of the first panel 11 to separate the first panel 11 and the second panel 12. In this regard, by devising the following method for attaching the support frame 20 to the animal invasion prevention fence 10, the animal invasion prevention fence 10 is hooked on the net wire rod 11b with the hooking portion 12c, and the first panel 11 The animal invasion prevention fence 10 can be folded and transported while the second panel 12 and the second panel 12 are connected to each other.

FIG. 8 is a diagram showing a state in which the animal invasion prevention fence 10 of another embodiment is constructed. In the animal invasion prevention fence 10 of FIG. 8, the support frame 20 is connected to the first panel 11 via the first ring 21 and the second ring 22. By attaching the support frame 20 to the first panel 11 via the two rings (first ring 21 and second ring 22) in this way, the support frame 20 has a high degree of freedom with respect to the first panel 12. (For example, it can rotate in the direction of arrow B or arrow C in FIG. 8). Therefore, if the third ring 23 is provided at the tip of the support frame 20, the support frame 20 is oriented in the direction of arrow B in FIG. 8 when the animal invasion prevention panel 10 is installed (when the support frame 20 is used). The third ring 23 is fitted into the end of the lateral mesh wire 12b in the second panel 12 to keep the support frame 20 in a stretched state, while the animal invasion prevention panel 10 is being transported. Folds the second panel 12 in the direction of arrow D in FIG. 8 with respect to the first panel 11, and rotates the support frame 20 in the direction of arrow C in FIG. 8 to move the third ring 23 into the first panel 11. It becomes possible to fit and fix the fixed portion 11e provided in the above.

Further, in the animal invasion prevention fence 10 of the present invention, as shown in FIG. 1, when a plurality of animal invasion prevention fences 10 are constructed side by side, it is possible to devise a connecting structure of adjacent animal invasion prevention fences 10. it can. That is, by using the panel connector 40 shown in FIG. 8, it becomes possible to easily and firmly connect the adjacent animal invasion prevention fences 10. The panel connector 40 has a pair of spring arms 41 and 42 formed by bending one metal wire rod into a "U" shape. Hooks that can be locked to each other are provided at the lower ends of the spring arms 41 and 42, and the lateral mesh wire 11b of the first panel 11 is provided in the middle of the spring arms 41 and 42. A bent portion is provided so that it can be addressed to. As shown by the arrow F in FIG. 8, the panel connector 40 has an intermediate portion thereof located behind the adjacent first panel 11d in the adjacent animal invasion prevention fence 10, and the bent portion is each animal. The hooks are engaged with each other on the rear side in a state of being located on the front side of the lateral net wire rod 11b in the intrusion prevention fence 10, and are attached to the boundary portion of the adjacent animal intrusion prevention fence 10. .. As a result, the adjacent animal invasion prevention fence 10 can be firmly attached by the elasticity of the panel connector 40 by an easy method without using a bolt or the like.

By the way, in the animal invasion prevention fence 10 of FIGS. 1 to 5 described above, even if the invasion of the wild boar can be prevented, an animal having a jumping power such as a deer or a light animal such as a monkey is an animal invasion prevention fence. There is a possibility of jumping over 10 or climbing over. In this regard, by adopting the following configuration, the animal invasion prevention fence 10 can more reliably prevent the invasion of deer and monkeys.

FIG. 9 is a diagram showing a state in which the animal invasion prevention fence 10 of another embodiment is constructed. FIG. 10 is a view showing a state in which the animal invasion prevention fence 10 of FIG. 9 is being constructed, and a state in which the additional rod 13a is inserted into the upper end portion of the first panel 11. FIG. 11 is a view showing a state in which the animal invasion prevention fence 10 of FIG. 9 is being constructed, and after the additional rod 13a is inserted into the upper end portion of the first panel 11.

9 to 11 and FIGS. 12 and 13 described later also show the x-axis, the y-axis, and the z-axis as in FIGS. 1 to 5 and the like. The orientations of the x-axis, y-axis, and z-axis are common in FIGS. 9 to 13. In the following, for convenience of explanation, the animal invasion prevention fence 10 shown in FIGS. 1 to 5 is referred to as "animal invasion prevention fence 10 of the first embodiment", and the animal invasion prevention fence 10 shown in FIGS. 9 to 13 is referred to as "the first. It may be referred to as "animal invasion prevention fence 10" of the second embodiment. Regarding the animal invasion prevention fence 10 of the second embodiment, only the part different from the animal invasion prevention fence 10 of the first embodiment will be described, and the description of the part common to the animal invasion prevention fence 10 of the first embodiment will be omitted. As the configuration not mentioned in the animal invasion prevention fence 10 of the second embodiment, the same configuration as the animal invasion prevention fence 10 of the first embodiment can be adopted.

In the animal invasion prevention fence 10 of the first embodiment, as shown in FIG. 2, nothing was arranged on the upper side of the first panel 11. On the other hand, in the animal invasion prevention fence 10 of the second embodiment, as shown in FIG. 9, the extension panel 13 is attached to the upper side of the first panel 11. In the animal invasion prevention fence 10 of the second embodiment, the height of the animal invasion prevention fence 10 is increased by the extension panel 13, and an animal having a jumping power such as a deer or a light animal such as a monkey can invade. It is possible to prevent it more reliably. In the animal invasion prevention fence 10 of the second embodiment, the extension panel 13 is provided as follows.

That is, in the animal invasion prevention fence 10 of the first embodiment, as shown in FIG. 2, a horizontal net wire 11b is arranged at the uppermost edge of the first panel 11, and the upper end of the vertical net wire 11a is arranged. The part was not protruding. On the other hand, in the animal invasion prevention fence 10 of the second embodiment, as shown in FIG. 10, the horizontal net wire 11b is not arranged at the uppermost edge of the first panel 11, and the vertical net wire 11b is not arranged. The upper end of 11b protrudes upward. As shown in FIGS. 10 and 11, the replenishment rods 13a are attached to the upper ends of the vertical net wire rods 11b at predetermined intervals, and then the horizontal wire rods 13b are stretched between the replenishment rods 13a. As a result, the animal invasion prevention fence 10 can be extended upward.

The height of the extension panel 13 (the length of the replenishment rod 13a) is not particularly limited, but if it is too low, the significance of providing the extension panel 13 is reduced. Therefore, the height of the extension panel 13 is usually 30 cm or more. The height of the extension panel 13 is preferably 50 cm or more, and more preferably 70 cm or more. There is no particular upper limit to the height of the extension panel 13, but it is usually 1 to 2 m in consideration of the balance of attachment of the extension panel 13.

The replenishment rod 13a need not be attached to all the vertical mesh wires 11a in the first panel 11. In the examples of FIGS. 9 to 11, every 10 rods are added to the vertical mesh wire rod 11a and the rods 13a are attached. Further, the horizontal wire members 13b constituting the extension panel 13 may be provided in only one (only one stage), but it is preferable to provide a plurality of horizontal wires 13b (in a plurality of stages). Thereby, the extended height of the animal invasion prevention fence 10 can be increased. As the horizontal wire member 13b, a wire-shaped material such as a wire rope or a string, or a tape-shaped material can be used. It is also possible to make the horizontal wire 13b conductive and to pass an electric current through the horizontal wire 13b. This makes it possible to more reliably prevent the invasion of animals. The configuration in which an electric current is passed through the horizontal wire rod 13b exerts a particularly great effect on monkeys. When a current is passed through the horizontal wire 13b, the current may be passed through all the horizontal wires 13b, but it is sufficient to pass the current only through the uppermost horizontal wire 13b.

The replenishment rod 13a is not particularly limited as long as it can be attached to the upper side of the first panel 11 and the horizontal wire rod 13b can be adjusted, but in the animal invasion prevention fence 10 of the second embodiment, FIG. The replenishment rod 13a of the aspect shown in FIG. 13 is used. FIG. 12 is an enlarged perspective view of the replenishment rod 13a of FIGS. 9 to 11. FIG. 13 is a cross-sectional view showing a state in which the replenishment rod 13a of FIG. 12 is cut by a plane including the center line thereof.

The replenishment rod 13a shown in FIGS. 12 and 13 has a rod shape extending in the vertical direction (z-axis direction). The cross-sectional shape of the replenishment rod 13a is rectangular as shown in FIG. 12, but other cross-sectional shapes such as a circular shape, an elliptical shape, and a polygonal shape can also be adopted. Further, the replenishment rod 13a may have a constant thickness, but the animal invasion prevention fence 10 of the second embodiment is formed in a tapered shape as shown in FIGS. 12 and 13.

As shown in FIG. 13, the replenishment rod 13a is provided with a _{first panel mounting hole 13a 1 upward from the lower end surface thereof.} The first panel mounting hole 13a ₁ is a portion for inserting the upper end portion of the net wire rod 11a in the vertical direction in the upper panel 11, and is the same as the height of the portion protruding upward at the upper end portion of the net wire rod 11a. It is formed to a depth of or deeper. In the animal invasion prevention fence 10 of the second embodiment, the height of the portion protruding upward at the upper end portion of the net wire rod 11a in the vertical direction is set to about 10 cm, and the depth _{of the first panel mounting hole 13a 1 of the replenishment rod 13a is set.} Is about 11 cm. _{A downward convex portion 13a 7} is provided on the side of the opening _{of the first panel mounting hole 13a 1} at the lower end portion of the replenishment rod 13a. The downward convex portion 13a ₇ comes into contact with the outer peripheral portion of the lateral mesh wire rod 11b when the upper end portion of the vertical mesh wire rod 11a (FIG. 10) is inserted into the first panel mounting hole 13a of the replenishment rod 13a. It is a part. As a result, the stability of the replenishment rod 13a attached to the first panel 11 can be improved.

The inner diameter of the first panel mounting hole 13a ₁ may be constant, but in the animal invasion prevention fence 10 of the second embodiment, the first panel mounting hole 13a ₁ is formed in a tapered shape as shown in FIG. The inner diameter of the first panel mounting hole 13a ₁ becomes smaller as it goes to the upper side. Therefore, while easily inserting the Amisen member 11a to the first panel mounting holes 13a _1, is after once inserted the Amisen member 11a to the first panel mounting holes 13a _1, mesh wire 11a from the first panel mounting holes 13a ₁ Can be made difficult to come off. Further, in the animal invasion prevention fence 10 of the second embodiment, after inserting the upper end portion of the net wire rod 11a in the first panel 11 into the first panel _{mounting hole 13a 1 of the replenishment rod 13a, a bolt is bolted from the outer peripheral portion of the replenishment rod 13a.} By inserting an insertion fixture (not shown) such as, etc. inward, the outer peripheral surface of the net wire rod 11a is pressed by the tip of the insertion fixture, and the net wire rod 11a is fixed in _{the first panel mounting hole 13a 1.} I am trying to do it.

Further, as shown in FIGS. 12 and 13, the replenishment rod 13a is provided with _{horizontal wire rod mounting grooves 13a 2} , 13a ₃ , 13a ₄ , 13a ₅ , 13a _6. As shown in FIG. 9, the horizontal wire rod 13b is inserted into the horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a _6. As a result, each of the horizontal wire rods 13b can be worn in a stretched state and supported by the rod 13a. _{The horizontal wire rod mounting groove 13a 2} provided at the upper end of the replenishment rod 13a is a portion for mounting the horizontal wire rod 13b arranged at the top (uppermost stage), and is provided on the outer peripheral portion of the replenishment rod 13a. The horizontal wire rod mounting grooves 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ are used to mount the horizontal wire rods 13b arranged at the bottom (bottom stage) from the horizontal wire rods 13b arranged in the second row from the top. It is a part of.

Of the horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ , the horizontal _{wire rod mounting groove 13a 3 at} the upper end of the replenishment rod 13a is provided with a notch downward from the upper end surface of the replenishment rod 13a. It is formed. On the other hand, the horizontal wire rod mounting grooves 13a ₃ , 13a ₄ , 13a ₅ , 13a _{6 on} the outer peripheral portion of the additional rod 13a are provided by forming a plate-shaped piece upward on the outer peripheral portion of the additional rod 13a. The replenishment rod 13a having such a form can be formed, for example, by injection molding a resin. The horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ can also be formed by later making a notch in the replenishment rod 13 formed in a simple rod shape.

The arrangement and number of the horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , and 13a _{6 are not particularly limited.} However, if the number of horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ (the number of horizontal wire rods 13b) is small, the height of the extension panel 13 cannot be secured, and it is significant to provide the extension panel 13. Decreases. Therefore, the number of horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ is preferably two or more. The number of horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ is more preferably 3 or more, and further preferably 4 or more. The horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ are preferably provided at intervals of 10 to 20 cm in the vertical direction. There is no particular upper limit to the number of horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a _{6, but usually up to about 10.}

Subsequently, a modified example of the replenishment rod 13a will be described. In the following, two examples (first modification and second modification) will be described as modification of the replenishment rod 13a.

First, the replenishment rod 13a of the first modification will be described. FIG. 14 is an enlarged perspective view showing a first modified example of the replenishment rod 13a. FIG. 15 is a cross-sectional view showing a state in which the replenishment rod 13a of the first modification is cut by a plane including the center line thereof. Regarding the replenishment rod 13a of the first modification, only the part different from the replenishment rod 13a shown in FIGS. 12 and 13 (hereinafter, may be referred to as “basic replenishment rod 13a”) will be described, and only the portion different from the replenishment rod 13a of the basic form The explanation of the part common to the replenishment rod 13a is omitted. As the configuration not mentioned in the replenishment rod 13a of the first modification, the same configuration as the basic replenishment rod 13a can be adopted.

In the basic replenishment rods 13a shown in FIGS. 12 and 13, the lateral mesh wire rod 11b (see FIG. 9) in the first panel 11 is supported _{by the downward convex portion 13a 7 provided at the lower end of the replenishment rod 13.} It was supposed to be done. Further, the basic type replenishment rod 13a has a structure in which the net wire rod 13a in the lateral direction in the first panel 11 is supported only by the net wire rod 11b at the uppermost stage. Therefore, when the basic type replenishment rod 13a is attached to the upper side of the first panel 11 (when the vertical mesh wire material 11a of the first panel 11 is inserted into _{the first panel mounting hole 13a 1 of the replenishment rod 13a).} Since the replenishment rod 13a is supported only in the vicinity of the lower end portion, it is not always easy to maintain the stability of the replenishment rod 13a, for example, the replenishment rod 13a may wobble.

In contrast, in the replenishment rod 13a of the first modification shown in FIGS. 14 and 15, it is deeply form a first panel mounting holes 13a _1, first to the first panel mounting holes 13a ₁ of the shirttail rod 13a When the vertical mesh wire 11a in the panel 11 is inserted, the lower end of the replenishment rod 13a reaches the second step from the top of the horizontal mesh wire 11b in the first panel 11. _{For this reason, in the replenishment rod 13a of the first modification, slits 13a 8} for guiding the net wire rod 11b in the lateral direction from the lower end of the replenishment rod 13a are provided substantially parallel to the first panel mounting hole 13a _1.

At a _{predetermined location in the slit 13a 8} (a location where the uppermost lateral net wire 11b and the second horizontal net wire 11b from the top are located when the replenishment rod 13a is attached to the first panel 11). Is provided with _{a locking recess 13a 9} for locking the net wire rod 11b in the lateral direction of the first panel 11. By locking the net wire rod 11b in the lateral direction to the locking recess 13a ₉ , the vertical position of the additional rod 13a can be positioned with respect to the net wire rod 11b in the lateral direction. Like the replenishment rod 13a of the first modification, the replenishment rod 13a is formed on the upper side of the first panel 11 by deeply forming _{the first panel mounting hole 13a 1 and providing the slit 13a 8} and the locking recess 13a _9. When attached to, the replenishment rod 13a can be stabilized and the replenishment rod 13a can be made less likely to wobble.

Further, in the basic type replenishment rod 13a shown in FIGS. 12 and 13, of the horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ for mounting the horizontal wire rod 13b of the extension panel 13, the horizontal wire rod is attached. The grooves 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ are provided by forming a plate-shaped piece upward on the outer peripheral portion of the replenishment rod 13a, and the horizontal wire member 13b is attached to the replenishment rod 13a by attaching the horizontal wire rod. This was done by inserting the horizontal wire 13b from the upper side to the lower side of the grooves 13a ₃ , 13a ₄ , 13a ₅ , 13a _6. Therefore, even if the horizontal wire rod 13b is attached to the horizontal wire rod mounting grooves 13a ₃ , 13a ₄ , 13a ₅ , 13a _{6, the horizontal wire rod 13b may loosen.}

On the other hand, in the replenishment rod 13a of the first modification shown in FIGS. 14 and 15, disc-shaped protrusions are provided at a plurality of locations on the outer peripheral portion of the replenishment rod 13a, and the inner surface (replenishment) of each disc-shaped protrusion is provided. The annular groove formed in the gap between the surface on the side facing the rod 13a and the outer surface of the replenishing rod 13a becomes the horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ . The horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , and 13a ₆ are provided in an annular shape over the entire circumference of the respective disc-shaped protrusions. Therefore, as shown in the enlarged portion of FIG. 14, the horizontal wire rod 13b is inserted into _{the annular groove (horizontal wire rod mounting groove 13a 2} , 13a ₃ , 13a ₄ , 13a ₅ , 13a _{6) inside the disk-shaped protrusion.} It can be wrapped around. Therefore, it is possible to prevent the horizontal wire 13b attached to the horizontal wire mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a _{6 from} moving in the length direction and to prevent the horizontal wire 13b from loosening. ing.

The disc-shaped protrusions that form the horizontal wire rod mounting grooves 13a ₂ , 13a ₃ , 13a ₄ , 13a ₅ , 13a ₆ are made separately from the main body of the replenishment rod 13a, and are later replenished to the main body of the rod 13a. Although it may be fixed, it is preferable that it is integrally molded with the main body portion of the replenishment rod 13a. In this respect, if the molding die of the replenishment rod 13a has a structure divided into left and right (a structure divided in the x-axis direction), the replenishment rod 13a having the above-described form can be injection-molded.

Subsequently, the replenishment rod 13a of the second modification will be described. FIG. 16 is a perspective view showing the front side of the replenishment rod 13a of the second modification. FIG. 17 is a perspective view showing the back surface side of the replenishment rod 13a of the second modification. FIG. 18 is a perspective view showing a state in which the replenishment rod 13a of the second modified example is replenished up and down from the back surface side. As for the enlarged portion of FIG. 18, for convenience of explanation, the additional rod 13a added to the upper side is shown by shaded hatching.

Regarding the replenishment rod 13a of the second modification, only the part different from the replenishment rod 13a of the first modification shown in FIGS. 14 and 15 will be described, and the part common to the replenishment rod 13a of the second modification will be described. Omit. As the configuration not mentioned in the replenishment rod 13a of the second modification, the same configuration as the replenishment rod 13a of the first modification and the replenishment rod 13a of the basic shape can be adopted.

In the replenishment rod 13a of the first modification shown in FIGS. 14 and 15, when the replenishment rod 13a in the slit 13a ₈ provided upward from the lower end surface of the replenishment rod 13a is attached to the first panel 11 (FIG. 11). _{Locking recesses 13a 9} are provided at a location where the uppermost lateral mesh wire 11b is located and at a location where the second lateral mesh wire 11b from the top is located, respectively. The net wire rod 11b in the lateral direction is locked to the stop recess 13a _9.

On the other hand, in the replenishment rod 13a of the second modification, as shown in FIG. 17, a pair of left and right hooks 13a ₁₀ are provided in two stages at the lower part of the replenishment rod 13a, and the inner portion of _{each hook 13a 10 is provided.} Is provided with a locking recess 13a _9. The hook 13a ₁₀ is not only used when attaching the replenishment rod 13a to the first panel 11 (FIG. 11), but also replenishes another replenishment rod 13a on the upper part of one replenishment rod 13a as shown in FIG. It also makes it possible.

That is, as shown in FIG. 17, the replenishment rod 13a of the second modification has a pair of left and right notch portions 13a ₁₁ notched on the upper side surface thereof, and as shown in FIG. 18, the replenishment rod 13a on the lower side has a pair of left and right notch portions 13a 11. The lower part of the upper replenishment rod 13a is addressed to one side (negative side in the y-axis direction) of the upper part, the lower hook 13a ₁₀ of the upper replenishment rod 13a is attached to the left and right notches 13a of the lower replenishment rod 13a. _{Each of them is inserted into 11} and locked, and the upper hook 13a ₁₀ of the upper replenishment rod 13a is locked to the upper end portion of the lower replenishment rod 13a to add another to the upper side of one replenishment rod 13a. The rod 13a can be added.

As a result, even if there is a risk that the target animal may jump over the animal invasion prevention fence 10 simply by adding the animal invasion prevention fence 10 and extending it by one step of the rod 13a, the additional rod 13a is arranged in two or more steps. As a result, the animal invasion prevention fence 10 can be further extended upward to more reliably prevent the invasion of animals. The number of the replenishment rods 13a of the second modification to be connected vertically is not particularly limited, but if too many rods are connected, the installation stability of the extension panel 13 may decrease. Therefore, the number of the replenishment rods 13a of the second modification to be connected vertically is usually up to 5, preferably up to 3.

In this way, when a plurality of additional rods 13a are connected vertically, the rigidity of the additional rods 13a may become a problem. However, in the additional rods 13a of the second modification, as shown in FIGS. 16 and 17, the front side thereof. _{A plurality of ribs 13a 12} are provided on the back side and the back side. As a result, the rigidity of the replenishment rod 13a can be increased.

Further, when connecting the replenishment rod 13a of the second modification vertically, as described above, the replenishment rod 13a on the lower side is replenished on one side (negative side in the y-axis direction) on the upper side. The lower part of the rod 13a is addressed. Therefore, in the replenishment rod 13a of the second modification, the _{disk-shaped protrusion forming the uppermost horizontal wire holding groove 13a 2} is formed in the horizontal direction (negative side in the y-axis direction) as in the replenishment rod 13a of the first modification. If it is provided in the direction of protruding from the above, the protrusions may interfere with each other when the replenishment rod 13a is connected up and down.

Therefore, in the replenishment rod 13a of the second modification, the replenishment rod _{forming the uppermost horizontal wire holding groove 13a 2} is provided upward as shown in FIG. 16, and the replenishment rod is connected to the upper side. It is designed not to interfere with 13a. In addition, as a method of preventing the protrusions forming the horizontal wire holding groove 13a ₂ from interfering with each other, a method of forming a notch or a recess in a portion of the replenishment rod where the protrusion can hit, or removing the protrusion. An example is a method of providing the device in a possible state. This applies not only to the protrusion forming the horizontal wire holding groove 13a ₂ on the uppermost stage, but also to other protrusions such as the protrusion forming _{the horizontal wire holding groove 13a 3} on the second stage from the top.
