Description

[Technical Field]

[0001] The present invention relates to an animal-proof fence that prevents animals from entering no-entry zones on expressways and the like, and in particular to an animal-proof fence that can guide animals into passable zones and prevent animals from entering no-entry zones. [Background technology]

[0002] Conventionally, when wild animals enter no-entry zones on expressways and other roads, it can cause traffic accidents and other problems, so animal-proof fences are installed near such no-entry zones along the no-entry zones.

[0003] Such animal-proof fences require a desired strength and height to prevent damage caused by animals colliding with them, or to prevent animals from entering by jumping over or digging through the ground where the fence is installed.

[0004] Furthermore, as described in Patent Document 1, the netting that makes up the animal-proof fence is made of threads containing capsaicin, which repels animals, so that when animals touch the fence, they are repelled and retreat from the fence, preventing them from entering the no-entry zone.

[0005] As described in Patent Document 2, such substances with animal repellent properties are known to be composed of a core substance made of a single or blend of plant essential oil extracts of herbs with animal repellent properties, encapsulated in a microcapsule with a water-soluble coating, and are known to contain capsaicin as the core substance.

[0007] However, conventional animal-proof fences exert their repellent effect when animals come into direct contact with the fence, such as by touching the fence with their face, biting it, or licking it.However, there is a problem in that if an animal were to jump over the fence, for example, it would be able to enter the no-entry zone.

[0008] Furthermore, near no-entry zones, passable zones that allow animals to enter are generally provided. These passable zones are, for example, bridges or tunnels that cross expressways, and allow animals to move to the other side of the expressway without entering the expressway. However, because such passable zones are provided in predetermined locations, there is a problem in that they cannot be used effectively unless animals are aware that they are allowed to pass through.

[0009] Therefore, the present invention has been made in consideration of the above problems, and aims to provide an animal-proof fence that can prevent animals from entering the no-entry zone and can guide animals into the pass-through zone to safely prevent animals from entering the no-entry zone. [Means for solving the problem]

[0010] The animal-proof fence of the present invention is an animal-proof fence that prevents animals from entering an intrusion-free zone, and includes an animal-proof fence body that is arranged approximately parallel to the edge of the intrusion-free zone, and a fence that guides the animals to a pass-through zone that allows the animals to enter. a pair and a guide fence, a pair The guide fence is In plan view Gradually towards the passable zone Horizontal Spacing So that it narrows V-shaped The animal-proof fence is arranged in a manner that its height from the ground surface gradually decreases as it approaches the passable zone, and the surface of the animal-proof fence body contains a repellent that repels animals when the animals come into contact with it.

[0011] In the animal-proof fence according to the present invention, it is preferable that the repellent contains microcapsules in which at least capsaicin is encapsulated.

[0012] In addition, in the animal-proof fence according to the present invention, it is preferable that the guide fence is arranged at an angle relative to the animal-proof fence main body.

[0013] In the animal-proof fence according to the present invention, it is preferable that the surface of the guide fence contains the repellent.

[0014] In addition, in the animal-proof fence according to the present invention, it is preferable that the concentration of the repellent contained in the guide fence is lower than the concentration of the repellent contained in the animal-proof fence body.

[0015] In addition, in the animal-proof fence according to the present invention, it is preferable that the concentration of the repellent contained in the guide fence varies along the extension direction of the guide fence.

[0016] The above summary of the invention does not list all of the necessary features of the present invention, and subcombinations of these features may also constitute inventions. [Effects of the Invention]

[0017] The animal-proof fence of the present invention comprises an animal-proof fence main body arranged approximately parallel to the edge of the no-entry zone, and a guide fence that guides animals to the pass-through zone that allows animals to enter, and the guide fence is configured so that its height gradually changes as it approaches the pass-through zone, and the surface of the animal-proof fence main body contains a repellent that repels animals when they come into contact with it.Therefore, in addition to guiding animals that approach the animal-proof fence to the pass-through zone by the guide fence, since the surface of the animal-proof fence main body contains the repellent, if an animal touches the animal-proof fence main body, it can be made to retreat from the animal-proof fence main body, thereby preventing animals from entering the no-entry zone.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0021] As shown in Figure 1, the animal-proof fence 10 of this embodiment comprises an animal-proof fence main body 11 arranged approximately parallel to a no-entry zone 1 that does not allow animals to enter, such as on a highway, and a guide fence 12 arranged at a predetermined distance from the animal-proof fence main body 11.

[0022] As shown in FIG. 2, for example, the animal-proof fence main body 11 includes support posts 15 arranged at a predetermined interval relative to the ground G, a wire mesh section 13 attached in a planar manner between the support posts 15, and a wire section 14 stretched horizontally above the wire mesh section 13. The lower part of the wire mesh section 13 may also include a stealth wire mesh 16 embedded in the ground G. This stealth wire mesh 16 may be configured integrally with the wire mesh section 13, or may be configured separately from the wire mesh section 13 so that it can be attached after the installation of the animal-proof fence main body 11. In this way, the provision of the stealth wire mesh 16 can prevent the intrusion of small animals, such as those that dig into the ground and slip through the animal-proof fence main body 11. Furthermore, in addition to the stealth wire mesh 16 embedded in the ground G, a wire mesh may also be installed at the ground level in the gap between the animal-proof fence main body 11 and the ground G.

[0023] The wire mesh portion 13 is formed as a diamond-shaped wire mesh, tortoiseshell wire mesh, or mesh (grid-like) made by weaving together coated wires 20, which are core wires covered with synthetic resin or the like, with a mesh size that is small enough to prevent animals from passing through. As shown in Figure 3, the coated wire 20 is made by applying adhesive 22 to zinc-plated iron wire 24, which has been surface-treated with zinc plating 23, and then extruding coating material 21 concentrically around the iron wire 24, which is the core wire, using an extrusion molding machine. Because the coated wire 20 is made with such an adhesive coating, it has high durability and can prevent the spread of corrosion of the iron wire 24 even if it is scratched.

[0024] Furthermore, the covering material 21 is made of a synthetic resin such as polyethylene mixed with a repellent. The repellent is preferably a microcapsule containing a spicy ingredient such as capsaicin, and the microcapsules are preferably formed to have a size of 15 to 25 μm.

[0025] In this way, by mixing a repellent into the covering material 21, when an animal comes into direct contact with the wire mesh portion 13 by touching it with its nose, biting it, licking it, or the like, the microcapsules are destroyed and the pungent ingredients and the like adhere to the animal, thereby providing a repellent effect, causing animals to retreat from the animal-proof fence main body 11 and preventing them from entering the impenetrable belt 1. Note that, like the wire mesh portion 13, the stealth wire mesh 16 is preferably structured with a core wire covered with a coated wire, and the mesh shape may be the same as that of the wire mesh portion 13, or may be changed as appropriate depending on the small animals that dig into the ground G.

[0026] The wire portion 14 may be a wire coated with the same coating material as the above-mentioned coating material 21 and stretched between the posts 15, or a wire not containing any repellent may be used.

[0027] The guide fence 12 is configured to guide animals to a passable zone 2 that is located near the no-entry zone 1 or that intersects with the no-entry zone 1. The passable zone 2 is, for example, a tunnel or underpass that passes under the no-entry zone 1, or a bridge that is built above the no-entry zone 1.

[0028] As shown in FIG. 1, the guide fence 12 is disposed at an angle relative to the animal-proof fence main body 11, and is disposed in a generally V-shape facing the passable zone 2.

[0029] As shown in Figure 4, the guide fence 12 is configured so that it gradually becomes taller as it approaches the passable zone 2. Specifically, the position farthest from the passable zone 2 (left side in Figure 4) has a first guide fence 12a which consists only of a wire mesh section 13, the position closest to the passable zone 2 (right side in Figure 4) has a third guide fence 12c which has a higher wire mesh section 13 and also has a wire section 14 arranged on it, and between the first guide fence 12a and the third guide fence 12c is a second guide fence 12b which has a wire section 14 arranged on top of the wire mesh section 13, similar to the animal-proof fence main body 11.

[0030] The guide fence 12 preferably uses a covering material 21 mixed with a repellent, similar to the animal-proof fence main body 11. Here, it is preferable that the concentration of the repellent mixed into the guide fence 12 is lower than the concentration of the repellent mixed into the animal-proof fence main body 11.

[0031] In this way, the concentration of the repellent is set higher in the animal-proof fence main body 11 than in the guide fence 12, so animals can be prevented from approaching the animal-proof fence main body 11, and as a result, animals can be prevented from entering the no-entry zone 1. Furthermore, even if an animal strays between the animal-proof fence main body 11 and the guide fence 12, it can be encouraged to move along the guide fence 12, which has a lower concentration of repellent.

[0032] It is also preferable that the concentration of the repellent mixed into the animal fence main body 11 and the guide fence 12 varies along the extension direction of the animal fence main body 11 and the guide fence 12. By configuring them in this way, it is possible to make the repellent effect different between places far from the passable zone 2 of the animal fence main body 11 and the guide fence 12 and places close to it, and to effectively evacuate animals that approach the animal fence main body 11 and the guide fence 12 or guide them to the passable zone 2.

[0033] By changing the concentration of the repellent in this way, animals approaching the animal-proof fence main body 11 and the guide fence 12 can be encouraged to move toward the passable zone 2. For example, if the concentration of the repellent is configured to decrease toward the passable zone 2, animals will be guided in the direction where the concentration of the repellent is decreasing, and if they move in the direction where the concentration of the repellent is increasing, they will be encouraged to move away from the animal-proof fence main body 11 and the guide fence 12, thereby preventing them from entering the no-entry zone 1.

[0034] As a specific method for changing the concentration of the repellent, a covering material 21 in which the repellent is mixed can be used for the entire wire mesh portion of the animal-proof fence main body 11 and the guide fence 12, and the repellent concentration can be mixed in so that it changes in any direction, or a repellent can be mixed into some of the covered wires 21 of the wire mesh portion to change the repellent concentration of the entire wire mesh portion.

[0035] In this way, with the animal-proof fence 10 of this embodiment, the repellent contained in the animal-proof fence main body 11 prevents animals from entering the no-entry zone 1 by causing them to retreat due to its repellent effect, and the guide fence 12 guides animals to the passable zone 2, thereby preventing animals from entering the no-entry zone 1.As a result, the synergistic effect of these two factors makes it possible to prevent animals from entering the no-entry zone 1.

[0036] Furthermore, as shown in Figure 5, it is preferable that the guide fence 35 is configured so that its height gradually increases toward the passable zone 2, and that the third guide fence 12c', which is positioned closest to the passable zone 2 and configured to have the highest height from the surface of the ground G, is equipped with a passage means 30 that allows animals to pass through.

[0037] The passage means 30 is configured to allow animals that have strayed between the animal-proof fence main body 11 and the guide fence 35 to pass through the guide fence 35 so that they can move to the opposite side of the guide fence 35 from the animal-proof fence main body 11, and is preferably configured, for example, as a covered opening 31 or tunnel 32 formed below the third guide fence 12c'.

[0038] As shown in Figure 6, the covered opening 31 is configured by a lid 18 that closes the opening 17 formed below the third guide fence 12c' from the side opposite the animal-proof fence main body 11, and the lid 18 can be rotated open and closed relative to the opening 17 via a hinge 19. With this configuration, if an animal wanders into the area between the animal-proof fence main body 11 and the guide fence 35, the animal that has wandered into the vicinity of the third guide fence 12c' can push open the lid 18 of the covered opening 31 from the side of the animal-proof fence main body 11, and move to the side of the guide fence 35 opposite the animal-proof fence main body 11, allowing the animal to escape from the intrusion prevention zone 1.

[0039] In addition, the covered opening 31 is configured so that the opening 17 is blocked by the cover 18 from the side opposite the animal-proof fence main body 11, and therefore it is not possible for animals to enter between the guide fence 35 and the animal-proof fence main body 11 from the side opposite the guide fence 35 from the animal-proof fence main body 11.

[0040] 7, the guide fence 40 may be configured so that its height from the ground surface G gradually decreases toward the passable zone 2. By installing the guide fence 40 in this manner, animals that stray between the animal-proof fence main body 11 and the guide fence 40 can easily jump over the guide fence 40 and escape from the no-entry zone 1. In this case, it is preferable to configure the concentration of the repellent contained in the guide fence 40 so that it gradually decreases toward the passable zone 2, as this will allow animals to be guided along the guide fence 40.

[0041] Furthermore, as shown in Figure 8, an embankment 33 may be formed so that the height of the guide fence 50 itself is constant, but the ground surface gradually rises toward the passable zone 2, and a tunnel 32 may be provided as a means of passage below the embankment 33. This configuration allows animals to easily jump over the guide fence 50 from above the embankment 33, and animals that do not jump can escape from the no-entry zone 1 by passing through the tunnel 32.

[0042] In this way, the height of the guide fence from the ground surface can be changed as appropriate depending on the animal behavior at the installation location. For example, in an environment where there are many jumping animals, the guide fence should be structured to make it easier for animals to jump over, while in an environment where there are many animals that tend to burrow underground, it is preferable to use stealth wire mesh 16 to prevent intrusion from underground and to use tunnels 32 to encourage animals to retreat from the guide fence.

[0043] In the above embodiment, the animal-proof fence main body 11 and the guide fence 12 are described as being composed of the wire mesh portion 13 and the wire portion 14, but the animal-proof fence main body 11 and the guide fence 12 may be composed of only the wire mesh portion 13 without the wire portion 14. Also, the guide fence 12 is described as having a stepped height, but the guide fence 12 may be formed so that its height increases continuously. It is clear from the claims that such modified or improved embodiments are also included within the technical scope of the present invention. [Explanation of symbols]
