[Technical field]

[0001] This invention belongs to the technical field of wild animal trapping fence structures that are installed on outdoor ground to guide and trap wild animals to a designated location. [Background technology]

[0002] In recent years, the population of wild animals has increased rapidly due to a decline in the hunting population and the aging of hunters. The increase in the population of wild animals belonging to the Cervidae, Bovidae, and Suidae families is particularly notable, and this has led to a continuous stream of widespread human damage, including damage to crops in agriculture, damage to reforestation and bark stripping in forestry, and damage caused by vehicle collisions in the transportation industry. Various techniques for capturing wild animals with the aim of preventing such damage have been disclosed (see, for example, Patent Documents 1 and 2).

[0003] As can be seen clearly in Figure 2, the remote control system for capturing harmful animals described in Patent Document 1 is composed of components such as edging material 14, intersecting wire material 15, etc., for the device main body (fence structure) for capturing wild animals. As can be seen from Figures 1 and 2, the animal capture device of Patent Document 2 has a device body (fence structure) for capturing wild animals that is made up of a fence unit consisting of vertical sides 11a and horizontal sides 11b and wire mesh 12 made of steel pipes or the like, and components such as posts 15.

[0014] Next, an embodiment of a fence structure for capturing wild animals according to the present invention will be described with reference to the drawings. EXAMPLES

[0015] The fence structure for capturing wild animals according to the present invention is a fence structure 10 for capturing wild animals, constructed by joining vertical members 1 and horizontal members 2 by means of fastening nuts 4 to bolts 3, as shown in Figure 1 etc., and is characterized in that the vertical members 1 and horizontal members 2 are both made of structural steel, an opening 5 formed by the vertical members 1 and horizontal members 2, which is provided within a height range that a captured wild animal can contact, is of a size that the wild animal cannot pass through and is not provided with any surface material such as wire mesh or netting, and the shaft 3a of the bolt 3 and the nut 4 are provided so as not to be exposed to the capture space S side of the fence structure 10. The main body of the fence structure 10 is constructed by continuously arranging fence units 10a, each of which is made up of the vertical member 1 and the horizontal member 2, in the horizontal direction.

[0016] FIG. 1 is a plan view showing the overall configuration of a fence structure 10 for capturing wild animals according to the present invention, FIGS. 2 to 7 are arrow views taken along lines AA to FF in FIG. 1, and FIGS. 8 to 15 are explanatory diagrams showing enlarged views of key parts (parts A to H) of FIGS. 2 to 4. In the drawing, reference numeral 6 denotes a reinforcing rib plate, reference numeral 7 denotes a brace (diagonal member) made of L-shaped steel, reference numeral 8 denotes a base plate, reference numeral 9 denotes an anchor, reference numeral 13 denotes a joint plate (attachment plate), and reference numeral 20 denotes a foothold for observers and the like. Reference numeral T denotes a facility for guiding and temporarily accommodating wild animals in the capture space S (hereinafter abbreviated as a detention facility), reference numeral X denotes the installation location of a trap lid attached to the fence structure 10, and reference numeral Y denotes the installation location of an entrance lid for guiding wild animals to the detention facility T.

[0017] Next, the configuration of the fence unit 10a which constitutes the main body of the fence structure 10 will be described. As shown in Figures 2 to 4, the fence unit 10a is formed in a frame shape by providing horizontal members 2 (channel steel 2) in three parallel tiers between vertical members 1 (pillar members 11) erected on the left and right (approximately 2 m wide in this embodiment), and the second and third tiers of horizontal members 2 from the top are arranged so that the channel steel 2 in the second tier opens downwards, and the channel steel 2 in the third tier opens upwards, as also shown in Figure 14. A number of (nine in the illustrated example) vertical frame members (angle steel) 12 are arranged at approximately equal intervals (approximately 20 cm wide in this embodiment) between the openings of the channel steels 2 arranged above and below, and the screen section is constructed by erecting them vertically using bolts 3 as joints.

[0018] Specifically, the bolt 3 joining means aligns bolt holes drilled in advance in the horizontal member 2 and the vertical frame member 12, passes the bolt 3 through the aligned bolt hole from the capture space S side, and fastens a nut 4 to join the horizontal member 2 and the vertical frame member 12 together, thereby erecting the vertical frame member (angle iron) vertically between the horizontal members (channel steel) 2 arranged above and below (see FIG. 14). In this way, by arranging the shaft 3a of the bolt 3 and the nut 4 so as not to be exposed to the capture space S side of the fence structure 10, the captured wild animal can be protected from injury.

[0019] Incidentally, the vertical frame members 12 are set to a height (about 2 m in this embodiment) that captured wild animals cannot jump over, and the openings 5 ​​formed between adjacent vertical frame members 12 are formed to a size (about 20 cm wide in this embodiment) that the wild animals cannot pass through. Moreover, the openings 5 ​​are not provided with surface materials such as wire mesh or netting.

[0020] The height dimension (about 2 m) and installation interval (about 20 cm) of the vertical frame members 12 are not limited to these, and are appropriately designed and changed according to the size and physical ability (especially jumping power) of the wild animals to be captured. In short, the structure is designed so that the captured wild animals cannot pass through (escape). Of course, the size of the horizontal members 2 is also appropriately designed and changed according to the structural design. For reference, the member sizes used in this embodiment are merely examples, and the pillars 11 are H-shaped steel 11 measuring 125×125×6.5×9 mm, with a height of about 3 m (2 m + 1 m) (the tall pillar 11 in the center of FIG. 2 is about 2×2=4 m). The horizontal members 2 are channel members 2 measuring 125×65×6×8 mm, with a length of about 2 m (the horizontal members 2 at both ends of FIG. 2 are about 1 m). The vertical frame members 12 are angle steel 12 measuring 50×50×6 mm, with a height of about 2 m as mentioned above.

[0021] Next, the structure of the fence structure 10 other than the main body (the fence unit 10a) will be described.

[0022] The bracing members (diagonal members) 7 provided at both ends in Fig. 2 are made of L-shaped steel 2 measuring 100 x 100 x 10 mm, and as shown in Fig. 1, two are provided at right angles when viewed from the planar direction, thereby increasing the strength and rigidity of the fence structure 10 to be constructed and stabilizing it. The four bracing members 7 are each attached at their upper ends by bolt fastening means to the middle of the flanges of the pillars 11 that make up the fence unit 10a, via joint plates 13 to which they are welded (see also Fig. 15), and their lower ends are attached by fastening means such as welding to a base plate 8 fixed with anchors 9 (see also Figs. 3 and 4). For reference, the component sizes used in this embodiment are merely an example; a square flat steel plate of 400 x 400 x 12 mm is used for the base plate 8, and a round steel bar with a diameter of 75 mm and a length of approximately 1 m is used for the anchors 9. In this embodiment, four anchors 9 are disposed at the corners of one base plate 8. The base plate 8 and the anchor 9 are used as supporting members for the bracing member 7, and also as supporting members for one end of the channel member 2 that opens upward and is placed on the ground, as shown in Figures 5 to 7. In this embodiment, the one end of the channel member 2 is welded to the upper surface of the base plate 8.

[0023] In addition, in the center of FIG. 2, a trap lid (not shown) is attached to the X section between adjacent pillars 11, which are 4m long by adding two 2m-high pillars 11 (see also FIG. 6). This trap lid is installed so that it can be automatically dropped by automatic control or manually. When guiding wild animals such as deer into the capture space S, it is always positioned at the top, and it is automatically dropped when the animals are captured. Similarly, in the center of FIG. 5, an introduction port (not shown) is attached to the Y section between adjacent pillars 11, which are 4m long by adding two 2m-high pillars 11. This introduction port is also installed so that it can be automatically dropped by automatic control or manually, and it is always positioned at the top when guiding wild animals such as deer into the containment facility T, and it is automatically dropped when the animals are captured.

[0024] In this embodiment, the fence structure 10 is attached to the storage facility T as shown in Figure 1, thereby allowing movement therethrough, but this is not limited to this. Of course, it can also be formed in an endless shape that surrounds the capture space S in a plan view, as shown in Figures 16 and 19.

[0025] Next, a joining structure using the bolts 3 for the fence structure 10 will be described.

[0026] For example, Figures 8A to 8C are explanatory diagrams of part A in Figure 2, in which the top of a pillar material (H-shaped steel) 11 extended to a height of 4 m and a horizontal member (channel steel) 2 of 1.2 m in length with an opening facing downwards are connected by a joining means of bolts 3 via two joint plates 13 welded to each of them. Incidentally, the nuts 4 in the figure are welded nuts, and the efficiency of the work is improved by previously welding them to the joint plate 13 on the side of the pillar material (H-shaped steel) 11. The reinforcing rib plate 6 provided at the joint between the pillar material 1 and the cross member 2 is provided at the center of the web of the channel steel 2. The shaft 3a and nut 4 of the bolt 3 are hidden by the flange of the pillar 1 and cannot be seen from the capture space S. However, since part A in Fig. 2 is located 4 m above the ground, even if the shaft 3a and nut 4 of the bolt 3 were exposed, there is no risk of injury to the captured wild animal if they come into contact with them.

[0027] 9A to 9C are explanatory diagrams of part B in Fig. 4, in which the top of a pillar (H-shaped steel) 11 with a height of 3m (2m + 1m) and a horizontal member (channel steel) 2 with a length of 2m and an opening pointing downwards are connected by joining means of bolts 3 to a flange of the pillar 11 and a joint plate 13 attached by welding to the horizontal member (channel steel) 2. A reinforcing rib plate 6 provided at the joint between the pillar 1 and the horizontal member 2 is provided in the center of the web of the channel steel 2. The shaft 3a and nut 4 of the bolt 3 are hidden by the flange of the pillar 1 and cannot be seen from the capture space S. However, since part B in Fig. 4 is located 3 m above the ground, even if the shaft 3a and nut 4 of the bolt 3 were exposed, there is no risk of injury to the captured wild animal if they come into contact with them.

[0028] Figures 10A to 10C are explanatory diagrams of part C in Figure 2, in which a 4m-tall pillar material (H-shaped steel) 11 at a height of 2m in the middle part is connected to a 2m-long cross member (channel steel) 2 with an opening facing downwards by a joining means of bolts 3 via two joint plates 13 welded to each of them. Incidentally, the nuts 4 in the figure are welded nuts, and are welded in advance to the joint plate 13 on the pillar (H-shaped steel) 11 side to improve work efficiency. The reinforcing rib plate 6 provided at the joint between the pillar 1 and the cross member 2 is provided at the center of the web of the channel steel 2. Meanwhile, the joint plates 13, bolts 3, and weld nuts 4 located at the top and bottom of Fig. 10B are used to butt-join pillars 11 with a height of 2 m in the vertical direction. The shaft 3a and nut 4 of the bolt 3 are hidden by the flange of the pillar 1 and cannot be seen from the capture space S. Therefore, there is no risk of the captured wild animal coming into contact with them and being injured.

[0029] 11A-C are explanatory diagrams of part D in FIG. 3, in which a 4m-high pillar (H-shaped steel) 11 is connected at a height of 2m in the middle of the pillar (H-shaped steel) and a 2m-long horizontal member (channel steel) 2 with an opening facing downward, by a joint means of bolts 3 between the flange of the pillar 11 and a joint plate 13 attached to the horizontal member (channel steel) 2 by welding. The joint plate 13 and bolts 3 also play a role in butt-joining the pillar 11 in the vertical direction. A reinforcing rib plate 6 provided at the joint between the pillar 1 and the horizontal member 2 is provided in the center of the web of the channel steel 2. Meanwhile, the joint plate 13, bolts 3, and nuts 4 located on the left side of FIG. 11A are used to butt-join the 2m-high pillar 11 in the vertical direction. The shaft 3a and nut 4 of the bolt 3 are hidden by the flange of the pillar 1 and cannot be seen from the capture space S. Therefore, there is no risk of the captured wild animal coming into contact with them and being injured.

[0030] 12A and 12B are explanatory diagrams of part E in Fig. 1, in which a horizontal member (channel steel) 2 with openings facing upward in three right-angled directions is connected to the lower end of a 4m-tall pillar (H-shaped steel) 11 by fastening means using bolts 3. Specifically, the pillar (H-shaped steel) 11 and the channel steels 2 provided on the left and right are connected by fastening means using bolts 3 via two joint plates 13 welded to each of them. The remaining central horizontal member (channel steel) 2 is connected by fastening means using bolts 3 between the flange of the pillar 11 and the joint plate 13 provided on the horizontal member (channel steel) 2 by welding. Incidentally, the nuts 4 in the figure are welded nuts, and the efficiency of the work is improved by previously welding them to the joint plate 13 on the side of the pillar material (H-shaped steel) 11. The reinforcing rib plate 6 provided at the joint between the pillar material 1 and the cross member 2 is provided at the center of the web of the channel steel 2. The shaft 3a and nut 4 of the bolt 3 are hidden by the flange of the pillar 1 and cannot be seen from the capture space S. Therefore, there is no risk of the captured wild animal coming into contact with them and being injured.

[0031] 13A-C are explanatory diagrams of part F in FIG. 2, in which a horizontal member (channel steel) 2 with openings provided upward in three right-angled directions is connected to the lower end of a 4m-high pillar (H-shaped steel) 11 by a bolt 3 fastening means. Specifically, the pillar (H-shaped steel) 11 and the channel steel 2 provided on the left and right sides are connected by a bolt 3 fastening means via two joint plates 13 welded to each of them. Also, the pillar (H-shaped steel) 11 and the channel steel 2 provided above and below are connected by a bolt 3 fastening means between the flange of the pillar 11 and the joint plate 13 provided by welding to the horizontal member (channel steel) 2. Incidentally, the nut 4 in the figure is a welded nut, and is welded to the joint plate 13 on the pillar (H-shaped steel) 11 side in advance to improve the efficiency of the work. The reinforcing rib plate 6 provided at the joint between the pillar 1 and the horizontal member 2 is provided at the center of the web of the channel steel 2. The shaft 3a and nut 4 of the bolt 3 are hidden by the flange of the pillar 1 and cannot be seen from the capture space S. Therefore, there is no risk of the captured wild animal coming into contact with them and being injured.

[0032] Therefore, as explained above, the fence structure 10 of the present invention is constructed by joining vertical members 1 (e.g., H-shaped steel 11, angle steel 12) and horizontal members 2 (channel members 2) with a bolt means that fastens nuts 4 to bolts 3, and the opening 5 formed by the vertical members 1 and the horizontal members 2, which is provided at a height range where the captured wild animals can come into contact with them (in this embodiment, approximately 2 m from the ground), is of a size that the wild animals cannot pass through, and is not provided with any surface material such as wire mesh or net, and is characterized in that the shaft 3a of the bolt 3 and the nut 4 are not exposed to the capture space S side of the fence structure 10.

[0033] In this way, the fence structure 10 for capturing wild animals according to the present invention is constructed by joining vertical members 1 (e.g., H-shaped steel 11, angle steel 12) and horizontal members 2 (channel members 2) with a bolt means that fastens nuts 4 to bolts 3. Therefore, it can be dismantled by releasing the fastening state between the bolts 3 and the nuts 4, and is a portable structure that can be reconstructed at the next installation site, and also has the following effects. (1) Since the fence structure 10 is constructed using structural steel such as H-shaped steel 11, channel steel 2, and angle steel 12, it is possible to realize a wild animal capture fence structure 10 that has high strength and rigidity, and is sufficiently able to withstand wind loads, snow loads, or collisions (impacts) with wild animals such as deer, and has excellent strength, rigidity, and durability. (2) Since the bolt shaft 3a and the nut 4 are not exposed to the capture space S, a fence structure 10 for capturing wild animals can be realized that is extremely safe and does not injure captured wild animals such as deer. (3) In the past, when a fence structure (main body of the device) was constructed using aggregates, wire materials, or wire mesh, damage to the aggregates, wire materials, or wire mesh could result in injuries to the legs of wild animals such as deer that came into contact with the damaged area. In the present invention, a fence structure 10 for capturing wild animals that is safe and does not cause the above-mentioned injuries can be realized by using shaped steel with high strength and rigidity. (4) Since a three-dimensional structure with excellent flexibility and deformability can be constructed using structural steel as the main component, a fence structure 10 for capturing wild animals can be realized that can easily be attached with a trap drop lid material or an entrance lid to a containment facility, or that can be easily connected to a facility T for temporarily containing wild animals. (5) Since a three-dimensional structure with excellent flexibility and deformability can be constructed using structural steel as the main component, it is possible to easily realize a fence structure 10 for capturing wild animals that has a height and component arrangement that prevents wild animals such as deer from jumping over it. (6) The opening 5 formed by the vertical members 1 and the horizontal members 2 made of structural steel is not provided with any surface materials such as wire mesh or netting, and has excellent visibility and transparency, making it possible to realize a fence structure 10 for capturing wild animals that can easily ease the fear of wild animals such as deer and easily guide them into the capture space. (7) It is possible to realize a fence structure 10 for capturing wild animals that is excellent in workability, economy, and rationality, since it can be repeatedly constructed and dismantled by tightening and loosening the bolts 3 and the nuts 4. In addition, it is possible to realize a fence structure 10 for capturing wild animals that is excellent in maintainability, since damaged members can be easily replaced. EXAMPLES

[0034] 16 to 22 show different examples of the above-mentioned Example 1 (see especially FIG. 16 and FIG. 19). The main difference between the wild animal capture fence structure 10 according to this Example 2 and the above-mentioned Example 1 is that it is formed in an endless shape (rectangular shape) surrounding the capture space S in a plan view, and that it does not have a bracing member 7. Also, compared to the above-mentioned Example 1, it is different in that it uses a vertical member 1' (approximately an I-shaped steel, or a reinforcing steel 11' that is a welded one-piece product that is approximately U-shaped in plan view and has a flange attached to the web portion) with a long web length. The other configurations are the same as those of the above-mentioned Example 1, so the same reference numerals are used and the description thereof is omitted as appropriate. Note that the illustration of the bolt 3 and the nut 4 is omitted for convenience, but the shaft portion 3a of the bolt 3 and the nut 4 are provided so as not to be exposed to the capture space S side of the fence structure 10.

[0035] That is, the fence structure for capturing wild animals according to the second embodiment is a fence structure for capturing wild animals constructed by joining vertical members 1 and horizontal members 2 by means of fastening nuts 4 to bolts 3, as in the first embodiment, and the vertical members 1 and horizontal members 2 are both shaped steel, the opening 5 formed by the vertical members 1 and horizontal members 2, which is provided within a height range where the captured wild animals can come into contact, is of a size that the wild animals cannot pass through, and is not provided with a surface material such as a wire mesh or net, and the shaft portion 3a of the bolt 3 and the nut 4 are provided so as not to be exposed to the capture space S side of the fence structure 10. In addition, the structure constructed by continuously providing fence units 10a consisting of the vertical members 1 and the horizontal members 2 in the horizontal direction remains unchanged. Furthermore, it remains unchanged that it is a relocatable structure that can be dismantled by releasing the fastening state between the bolts 3 and the nuts 4 and reconstructed at the next installation site. Therefore, the wild animal capturing fence structure 10 according to the second embodiment has the same operational effects as those of the first embodiment (for details, see paragraph

[0033] above).

[0036] Although an embodiment of the present invention has been described above with reference to the drawings, it should be noted that the present invention is not limited to the illustrated examples, and includes the scope of design modifications and application variations that would normally be made by a person skilled in the art, provided that the scope does not deviate from the technical concept of the present invention. For example, in the present embodiments 1 and 2, H-shaped steel 11, approximately I-shaped steel 11', or reinforcing steel 11' is used for the column material, angle steel is used for the vertical frame material 12, and channel steel is used for the horizontal material 2, but this is not limited to this and other steel shapes can also be used.
