Description

The present invention relates to an animal invasion prevention fence that prevents animals from invading a field or the like.

In recent years, agricultural damage caused by wild animals such as ino and deer has become more serious. As part of measures against such damage, the fields are fenced to prevent wild animals from invading the fields.

As such a fence, for example, there is an invention described in the following patent documents.

Patent Document 1 describes a directional guidance device for preventing the invasion of wild boar. Specifically, the direction guidance device includes a plurality of nets installed in multiple rows in the horizontal direction at positions above the ground by a predetermined height, a plurality of holding members for supporting the nets, and a holding member. It is provided with a plurality of ropes to be held and a plurality of columns to support the ropes. Therefore, when the boar steps into the direction guidance device to invade the buttock, the boar gets entangled with the net, and the net is caught between the hoofs such as the main hoof and the auxiliary hoof, causing discomfort. Give up the invasion of the buttock.

Patent Document 2 describes a fence using a wire mesh. Specifically, the fence here includes a plurality of strut units, a furring rod extending between the upper portions of adjacent strut units, and a rhombic wire mesh formed by winding a plurality of rows of wires. In addition, the thickness of the winding on the uppermost side of the diamond-shaped wire mesh is formed larger than the thickness of the other windings, and both ends of the furring rod inserted into the mesh on the uppermost side of the diamond-shaped wire mesh are connected to the pair of adjacent column units. It is laid horizontally between them, and a brace is stretched between the head of the extra length formed on the upper part of the main body of the column and the middle part of the furring rod. By doing so, it is possible to reliably prevent bending and deformation of the diamond-shaped wire mesh, and it is possible to provide a simple beast-proof fence that can be easily assembled and disassembled by a small number of people.

Patent Document 3 also describes a beast-proof fence using a wire mesh. Specifically, the beast-proof fence was extended by hanging it on a plurality of columns erected on the installation surface at intervals, a hanging rod laid between the upper parts of adjacent columns, and a hanging rod. It is equipped with a wire mesh. Further, the total height of the wire mesh is larger than the standing height of the columns, and the wire mesh has a strip-shaped laying portion in which the lower end thereof is bent along the installation surface and laid toward the front of the wire mesh. Such a configuration provides a beast-proof fence with low construction cost.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the same members are designated by the same reference numerals in principle, and the repeated description will be omitted. Further, in the following description, the inside is a direction toward the field 10, and the outside is a direction away from the field 10. Further, the left-right direction is the direction in which the animal invasion prevention fences 11 are lined up.

FIG. 1 is a top conceptual view showing an animal invasion prevention fence 11.

The field 10 is a field for cultivating root vegetables such as potatoes, potatoes and onions.

The animal invasion prevention fence 11 is installed so as to surround the entire circumference of the field 10 in order to prevent the animal 19 from invading the field 10 which is a predetermined area. By doing so, as will be described later, it is possible to prevent animals 19 such as wild boars from invading the field 10 and prevent root vegetables and the like cultivated in the field 10 from being devoured.

FIG. 2 is a perspective view showing the configuration of the animal invasion prevention fence 11. The field 10 shown in FIG. 1 is surrounded by a plurality of parallel animal intrusion prevention fences 11.

The animal intrusion prevention fence 11 mainly includes an insertion portion 12, an animal contact portion 13, and a guide portion 14.

The insertion portion 12 is a member having an opening 15 through which a part of the animal 19 can be inserted. The insertion portion 12 is a member in which rod-shaped steel materials having a thickness of about several mm are crossed and joined in a mesh shape. The size of the mesh is such that the legs 20 of the animal 19 described later can pass through, and for example, the mesh is a substantially square having a side length of 13 cm to 17 cm. Here, the mesh of the insertion portion 12 is the opening 15 through which the leg 20 of the animal 19, which will be described later, is inserted.

When the animal intrusion prevention fence 11 is installed, the installation portion 16 is configured to come into contact with the ground plane 17 on which the animal intrusion prevention fence 11 is installed. The ground plane 17 is not shown here. In the animal intrusion prevention fence 11 shown in FIG. 2, the insertion portion 12 also serves as the installation portion 16.

The animal contact portion 13 is configured such that the lower end side thereof is connected to the inner end side of the insertion portion 12 and a part thereof is arranged on the upper side of the insertion portion 12. The animal contact portion 13 is a member in which linear steel materials having a thickness of about several mm are crossed and joined in a mesh shape, similarly to the insertion portion 12. Here, the animal contact portion 13 is inclined upward toward the outside. By forming the animal contact portion 13 in such an inclined structure, the animal contact portion 13 can receive the lifting motion of the animal 19, as will be described later. Further, the animal contact portion 13 and the insertion portion 12 may be formed of one mesh-like member bent into a substantially L-shape having an acute angle at the bent portion.

The guide portion 14 is configured to guide the animal contact portion 13 and the insertion portion 12 so as to be movable only in the vertical direction. The guide portions 14 are arranged at both ends of the animal intrusion prevention fence 11 in the left-right direction. As the guide portion 14, a rod-shaped member can be adopted, and for example, a reinforcing bar can be adopted. The lower end of the guide portion 14 is embedded, for example, substantially perpendicular to the ground. Here, the guide portion 14 of the portion embedded in the ground is shown by a broken line.

The animal contact connecting portion 191 is a portion of the animal intrusion prevention fence 11 at both ends in the left-right direction, which connects the upper end portion of the animal contact portion 13 and the guide portion 14 so as to be movable only in the vertical direction. The animal contact connecting portion 191 is a substantially ring-shaped member made of, for example, a metal or a synthetic resin.

The installation connecting portion 192 is a portion that movably connects the intermediate portions on the left and right sides of the insertion portion 12 as the installation portion 16 and the guide portion 14 only in the vertical direction. The configuration of the installation connecting portion 192 is the same as that of the animal contact connecting portion 191.

FIG. 3A is a side view showing a state in which the animal 19 approaches the animal invasion prevention fence 11. Here, the wild boar is exemplified as the animal 19. First, the animal 19 attempting to invade the field 10 approaches the animal invasion prevention fence 11. At that time, the leg 20, which is the forefoot of the animal 19, is trampling the insertion portion 12.

FIG. 3B is a side view showing a state in which the animal 19 lifts the animal intrusion prevention fence 11. Animal 19 attempts to lift the animal intrusion prevention fence 11 using its nose and head. At that time, the animal 19 lifts the inclined animal contact portion 13 upward. As described above, the animal contact portion 13 and the insertion portion 12 are made movable in the vertical direction by the guide portion 14. Therefore, the animal contact portion 13 and the insertion portion 12 are lifted upward by the movement of the animal 19.

At that time, the leg 20 of the animal 19 is inserted through the opening 15 of the insertion portion 12. Therefore, when the animal 19 lifts the animal contact portion 13 upward, the insertion portion 12 also rises with the leg 20 inserted through the opening 15. Therefore, since the free movement of the leg 20 is hindered, the animal 19 instinctively dislikes such a state. In addition, the insertion portion 12 comes into contact with the lower part of the body of the animal 19, and the animal 19 instinctively dislikes such a state. By doing so, the animal 19 stops the operation of lifting the animal invasion prevention fence 11 for invasion, and gives up the invasion into the field 10. When the animal 19 stops lifting the animal intrusion prevention fence 11, the animal contact portion 13 and the insertion portion 12 fall to the upper surface of the ground contact surface 17 due to the action of gravity and return to the original state. Therefore, even after the animal 19 attempts to invade the field 10, it is possible to prevent the formation of a gap that allows the animal 19 to invade between the animal invasion prevention fence 11 and the ground plane 17. ..

FIG. 4A is a perspective view showing the configuration of the animal intrusion prevention fence 11 according to another embodiment of the present invention. The configuration of the animal intrusion prevention fence 11 shown in this figure is basically the same as that shown in FIG. 2, and the configurations of the insertion portion 12 and the installation portion 16 are different.

Here, the installation portion 16 is connected to the lower ends of both ends of the animal contact portion 13 in the left-right direction, and extends linearly toward the outside. As the installation portion 16, a rod-shaped member such as a steel rod or a plate-shaped member can be adopted. An installation connecting portion 192 is arranged in the middle of the installation portion 16, and the installation portion 16 is movably supported only in the vertical direction by a guide portion 14 through which the installation connecting portion 192 is inserted.

The insertion portion 12 is a separate member from the installation portion 16. As described above, the insertion portion 12 is made of a mesh-like member, and the side side of the inner end portion thereof is rotatably connected to the lower side of the animal contact portion 13 via the rotation support portion 21. The rotation support portion 21 is, for example, a binding member made of a wire or the like. A plurality of rotation support portions 21 are formed at substantially equal intervals along the inner side of the insertion portion 12.

FIG. 4B is a perspective view showing the configuration of the animal intrusion prevention fence 11 when it is lifted. In such a state, since only the inner side of the insertion portion 12 is rotatably connected to the lower side of the animal contact portion 13, only the inner end portion thereof is in an inclined state, and the outer end portion thereof is shown in the figure. Not in contact with the ground plane 17.

FIG. 5A is a diagram showing an animal invasion prevention fence 11 according to another embodiment of the present invention, and is a side view showing a state in which the animal 19 approaches the animal invasion prevention fence 11.

First, the animal 19 attempting to invade the field 10 approaches the animal invasion prevention fence 11, and the leg 20 of the animal 19 is trampling the insertion portion 12. Further, the insertion portion 12 is arranged on the upper surface of the ground contact surface 17 which is the ground.

FIG. 5B is a side view showing a state in which the animal 19 lifts the animal intrusion prevention fence 11.

The animal 19 uses its nose and head to lift the animal intrusion prevention fence 11. At that time, the animal 19 lifts the inclined animal contact portion 13 upward. As described above, the animal contact portion 13 and the installation portion 16 are movable in the vertical direction by the guide portion 14. Therefore, the animal contact portion 13 and the installation portion 16 are lifted upward by the animal 19. On the other hand, since only the inner side of the insertion portion 12 is rotatably connected to the lower side of the animal contact portion 13, only the inner end portion thereof rises, and the outer end portion contacts the ground plane 17 (not shown). is doing. That is, the insertion portion 12 is in an inclined state in which it is inclined downward toward the outside.

At that time, the leg 20 of the animal 19 is inserted through the opening 15 of the insertion portion 12. Therefore, when the animal 19 lifts the animal contact portion 13 upward, the insertion portion 12 also rises with the leg 20 inserted through the opening 15. Therefore, since the free movement of the leg 20 is hindered, the animal 19 instinctively dislikes such a state. By doing so, the animal 19 stops the operation of lifting the animal invasion prevention fence 11 for invasion, and gives up the invasion into the field 10. When the animal 19 stops lifting the animal invasion prevention fence 11, the animal contact portion 13 falls to the upper surface of the ground contact surface 17 due to the action of gravity. Further, the insertion portion 12 also rotates in the opposite direction and returns to the original state.

FIG. 6A is a perspective view showing an animal invasion prevention fence 11 according to still another form. The structure of the animal intrusion prevention fence 11 shown in this figure is basically the same as that shown in FIG. 4, and the shape of the insertion portion 12 is different.

Here, the insertion portion 12 is composed of a plurality of split insertion portions 121 having a strip shape. The inner end portion of the split insertion portion 121 is rotatably connected to the lower end portion of the animal contact portion 13 via the rotation support portion 21. In the left-right direction, the split insertion portions 121 may be arranged apart from each other or may be arranged so as to be in close contact with each other.

FIG. 6B is a perspective view showing a configuration when the animal intrusion prevention fence 11 having such a configuration is lifted.

When the animal contact portion 13 is lifted, the animal contact portion 13 and the installation portion 16 are guided by the guide portion 14 and rise substantially vertically. On the other hand, the split insertion portion 121 rotates with the inner end portion as the center of rotation, and the outer portion is in an inclined state in which the outer portion is inclined downward. In reality, all the split insertion portions 121 are in an inclined state, but here, only the split insertion portions 121 arranged at the left end are inclined. By doing so, the individual split insertion portions 121 can be rotated at different angles of rotation so as to follow the uneven shape of the ground on which the animal intrusion prevention fence 11 is installed. Therefore, even if the uneven shape of the ground contact surface 17 on which the animal invasion prevention fence 11 is installed is large, it is possible to prevent the animal 19 from invading when the animal contact portion 13 is lifted.

FIG. 7A is a perspective view showing the configuration of the animal intrusion prevention fence 11 according to still another form. The structure of the animal intrusion prevention fence 11 shown in this figure is basically the same as that shown in FIG. 1, except that it has a drooping portion 18.

The hanging portion 18 is a member arranged below the insertion portion 12, and a mesh-shaped or plate-shaped member can be adopted. The inner surface of the hanging portion 18 is rotatably connected to the lower side of the animal contact portion 13 via a plurality of rotational support portions 22. The hanging portion 18 is arranged substantially horizontally between the insertion portion 12 and the ground plane 17 when the animal 19 does not lift the animal contact portion 13. On the other hand, when the animal 19 is lifting the animal contact portion 13, the hanging portion 18 rotates around the rotation support portion 22 and is inclined downward toward the outside.

FIG. 7B is a side view showing a configuration when the animal intrusion prevention fence 11 having such a configuration is lifted. Here, by lifting the animal 19, the animal contact portion 13 and the insertion portion 12 are guided and raised by the guide portion 14. On the other hand, the hanging portion 18 is tilted by rotating around the rotation support portion 22 as the center of rotation, and its outer end portion is in contact with the ground contact surface 17. By doing so, even when the animal contact portion 13 and the insertion portion 12 rise, the drooping portion 18 closes the gap formed below the insertion portion 12, and the small animal 19 passes through the gap in the field. It is possible to prevent the invasion of 10.

FIG. 8A is a side view showing the configuration of the animal invasion prevention fence 11 according to still another form. The structure of the animal intrusion prevention fence 11 shown here is basically the same as that shown in FIG. 3A, except that it has a cylindrical connecting portion 193.

The tubular connecting portion 193 is a substantially tubular member having a central axis along the vertical direction, and for example, a cylindrical pipe made of a synthetic resin such as vinyl chloride can be adopted. The upper end side of the tubular connecting portion 193 is connected to the upper end side of the animal contact portion 13, and the lower end side of the tubular connecting portion 193 is connected to the installation portion 16. Further, a cylindrical connecting portion 193 is inserted through the intermediate portion of the guide portion 14.

With reference to FIG. 8B, when the animal 19 lifts the animal contact portion 13 upward, the animal contact portion 13 and the installation portion 16 rise while being guided by the guide portion 14 inserted through the tubular connecting portion 193. For example, the guide portion 14, which is a reinforcing bar, slides well on the inner surface of the cylindrical connecting portion 193. Therefore, by adopting the cylindrical connecting portion 193, the ascending operation of the animal contact portion 13 and the installation portion 16 becomes smooth. Similarly, the lowering motion of the animal contact portion 13 and the installation portion 16 becomes smooth.

The configuration that employs the cylindrical connecting portion 193 can also be applied to the animal intrusion prevention fence 11 shown in FIGS. 4A, 6A, 7A, and the like.

FIG. 9 is a perspective view showing the configuration of the animal intrusion prevention fence 11 according to still another form. The structure of the animal intrusion prevention fence 11 shown here is basically the same as that shown in FIG. 2, except that it has a weight portion 23.

Specifically, the weight portion 23 is a long member made of a material having a large specific gravity such as metal, and is arranged from the left end to the right end of the animal invasion prevention fence 11. As the weight portion 23, for example, a plurality of bundled reinforcing bars can be adopted. The weight portion 23 is fixed to the inner end portion of the installation portion 16 or the lower end portion of the animal contact portion 13. By adopting the weight portion 23, after the animal 19 lifts the animal contact portion 13 and the insertion portion 12, the falling motion of the animal contact portion 13 and the insertion portion 12 is promoted, and the space between the insertion portion 12 and the ground contact surface 17 is promoted. It is possible to suppress the formation of a gap in the animal.

The configuration in which the weight portion 23 is adopted can also be applied to the animal intrusion prevention fence 11 shown in FIGS. 4A, 6A, 7A and the like.

According to the present embodiment described above, the following main effects can be achieved.

That is, the invasion of the animal 19 can be effectively prevented. With reference to FIG. 3A, the animal 19 attempting to invade the field 10 first inserts the leg 20 into the insertion portion 12. Next, referring to FIG. 3B, when the animal 19 lifts the animal contact portion 13, the insertion portion 12 connected to the animal contact portion 13 is also lifted in a chain reaction to, for example, the base portion of the leg 20 of the animal 19. By doing so, the free movement of a part of the animal 19, for example, the forefoot, is restricted. Also, the animal 19 cannot lift the animal contact portion 13 any further. From this, the invasion of the animal 19 into the field 10 is prevented.

Further, with reference to FIG. 4A, by providing the installation portion 16 continuous from the lower end of the left-right end portion of the animal contact portion 13, the animal contact portion 13 can be stably installed at the installation location. ..

Further, referring to FIG. 4B, when the animal 19 lifts the animal contact portion 13, the insertion portion 12 is rotated to be tilted, and the outer end portion of the insertion portion 12 comes into contact with the ground plane 17. Therefore, the gap formed between the insertion portion 12 and the ground contact surface 17 does not become large, and it is possible to prevent the animal 19 from invading the field 10 through the gap.

Further, referring to FIG. 6B, the split insertion portions 121 are individually rotatably connected to the animal contact portion 13, so that the individual insertion portions 12 can rotate at an arbitrary angle, and the ground plane 17 and the insertion portion can be rotated. Even if the gap with 12 is made small and the unevenness of the ground contact surface 17 is large, it is possible to prevent the animal 19 from invading through the gap.

Further, referring to FIG. 2, since the animal contact portion 13 is inclined upward toward the outside, the cross-sectional shape of the animal invasion prevention fence 11 becomes substantially triangular, and the animal invasion prevention fence 11 has a substantially triangular shape. Machine strength can be improved.

Further, referring to FIG. 7B, when the animal contact portion 13 rises, the outer tip side of the droop portion 18 rotates downward, so that the gap between the animal contact portion 13 and the ground contact surface 17 is created by the droop portion 18. It is possible to prevent the animal 19 from invading the field 10 through the gap below the insertion portion 12 even when the animal contact portion 13 and the insertion portion 12 are lifted.

Although the embodiments of the present invention have been described above, the present invention is not limited to this, and changes can be made without departing from the gist of the present invention. In addition, the above-mentioned forms can be combined with each other.

For example, referring to FIG. 2, the animal contact portion 13 and the installation portion 16 may be made of a metal plate, a synthetic resin plate, a plate-shaped wood, or the like.

Further, in the animal intrusion prevention fence 11 shown in FIG. 2, two guide portions 14 are arranged at both ends in the left-right direction of the animal contact portion 13, but the position and number of the guide portions 14 are arbitrary. For example, the number of guide portions 14 may be 1 or 3 or more.
