Description

  The present invention relates to a wild animal invasion prevention device installed in a passage such as an agricultural forest road in order to prevent food damage caused by wild animals such as moths, deer, moths and moths on cultivated crops, planted seedlings and the like.

  Conventionally, damage to crops has been mainly caused by moths and deers, but in recent years, damage by complex beast species including these has increased due to the expansion of habitats such as moths and moths. In order to prevent food damage caused by wild animals, fences such as fences and iron nets are generally installed around farmland, and door fences that can be opened and closed are provided at the entrance, but people and vehicles enter and exit. Opening and closing the door fence each time is troublesome, and if you forget to close the door fence, wild animals may invade from it.

  In order to cope with this problem, Japanese Patent Application Laid-Open No. H10-228667 discloses a grid having an opening size that allows a leg of a wild animal to enter and a depth that does not reach the bottom of the hole even when the elbow joint or knee joint of the leg is stepped on. It has been proposed to install a panel or honeycomb-like panel (grating) at the entrance / exit of farmland or the like.

JP2011-160731A

  Wild animals have a habit of instinctively injuring leg injuries because injured legs are life-threatening. The panel disclosed in Patent Document 1 does not hinder people and vehicles from entering and exiting, but has a myriad of openings that allow wild animals to enter. It has the effect of holding the heart and preventing the invasion of wild animals such as sharks and deers, but in wild animals that do not have hoofs such as sharks and sharks Some individuals walk along the pier and invade.

  An object of this invention is to provide the wild animal invasion prevention apparatus which can prevent the invasion of a wild animal more reliably.

  The invention according to claim 1 is a wild animal intrusion prevention device installed to prevent a wild animal from entering a passage through which a vehicle or a person passes through the passage. A panel formed with a large number of openings on the front, rear, left and right to enter, and a sheet that covers the panel and is fixed by a fixing means, and the sheet has a cut into which a leg of a wild animal enters a position corresponding to the opening It is formed.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the sheet is made of a colored or opaque material so that the opening cannot be seen through.

  According to the first aspect of the present invention, when the wild animal steps into the sheet on the opening, the leg enters the opening through the cut, and the wild animal is feared to exert an invasion preventing effect.

  According to the second aspect of the present invention, since the wild animal cannot visually recognize the opening, it is difficult to walk along the panel rail avoiding the opening.

Hereinafter, a wild animal intrusion prevention device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an example of a panel constituting the apparatus. The panel 1 is arranged in a rectangular frame 2 with a main member 3 indicated by an arrow in a lateral direction toward an invasion direction of an animal which is an advancing direction of a passage ( The auxiliary member 4 is formed in a zigzag manner and fixed to the main member 3 by refracting peaks and valleys, and is integrated with the two members 3 and 4. A trapezoidal and rhomboid-shaped opening 5 of a species into which a leg of a wild animal enters is formed on the front, rear, left and right.

  In addition to the panel 1 shown in FIG. 1, for example, the main member 8 is arranged in parallel with the main member 8 in a rectangular frame 7 as shown in FIG. A panel 11 in which a rhombus opening 10 is formed so that a leg of a wild animal enters by both members 8 and 9 crossing the main member 8 in parallel, as shown in FIG. 14 are arranged in parallel at regular intervals in the lateral (left and right in FIG. 3) direction of the animal in the direction indicated by the arrow, and the auxiliary member 15 is inclined with respect to the direction of passage of the passage and the main member 14 at the same regular intervals. A panel 17 in which a large number of rhombus or parallelogram openings 16 are formed on both the front and rear and right and left sides so that a wild animal's foot can enter with both members 14 and 15, and a combination of a vertical (main) member and a horizontal (auxiliary) member A grid is formed, and the opening formed by the main member and auxiliary member is rectangular. No grating-like panel, the honeycomb forming the opening it is possible to use a panel or the like which forms a hexagonal or other openings can also be used panel forming a circle, an ellipse other arbitrary shape.

  FIG. 4 shows a rubber or resin sheet 18 to be put on the panel 1 shown in FIG. 1, which has weather resistance, abrasion resistance and strength to withstand biting and pulling by animals, and is preferably further colored or opaque. The main member 3, the auxiliary member 4, and the opening 5 are prevented from being seen through. The sheet 18 is also provided with cross-cuts 19 having the same pitch as that of the main member 3 in the horizontal direction (left and right direction in FIG. 4) and the same pitch as that of the auxiliary member 4 in the vertical direction (front and rear direction in FIG. 4). As shown in FIG. 5, the cut 19 has a large-diameter hole 21 at the center of the cross-shaped cut 19 and small holes 22 at the front, rear, left and right cut ends.

  The shape of the cut 19 is not limited to that shown in the figure. For example, the cut 19 is formed in a three-pronged shape from the large diameter hole 21 as shown in FIG. 6, or the large diameter as shown in FIG. May be formed radially (eight sides in the illustrated example) from the holes 21.

  The holes 21 and 22 described above are used to easily bend the sheet at the cut portion and make it easier for the animal's leg to enter. However, even if the holes 21 and 22 are not formed, the animal's leg can enter through the cut 19. Is possible.

  The sheet 18 shown in FIG. 4 is placed on the panel 1 shown in FIG. 4 so that a cross 19 is located at the center of the opening 5 (FIG. 8), and the side edge bending margin 23 (see FIG. 4). Is bent along the frame 2 and fixed to the frame 2 with screws 24 as fixing means (FIG. 9).

  The attachment of the sheet side edge to the frame 2 may be performed by a clip 26 as shown in FIG. 10 or may be bonded by an adhesive or a double-sided tape without using the screw 24 or the clip 26. In these cases, therefore, the fastening means is the clip 26, double-sided tape, or the like, but other fastening means may be used. The fastening means is not particularly limited as long as the sheet 18 can be fastened to the panel 1.

  The sheet to be put on the panel is formed in accordance with the shape of the opening in the sheet 18 for the panel having different pitches of the main member and the auxiliary member, or the panel having the above-mentioned various forms of opening. Then, the sheet 18 is mounted on the panel so that each cut is accommodated in the opening.

  The panel on which the seat 18 is mounted is formed so that the leg does not reach the bottom of the hole when the first joint of the animal leg enters the opening, but the height of the panel is not sufficient. When the elbow or knee joint of an animal leg enters the opening, if the leg hits the ground, the passage of the installation site is dug down so that it does not hit.
