Description

[Technical field]

[0001] The present invention relates to a device for driving out bats from their nests, and for preventing or obstructing their entry after driving them out. of Regarding construction methods. [Background technology]

[0002] In the past, damage caused by bats under the eaves of ordinary houses was common. In the event that bats invade, there were methods to repel them, such as bat sprays, repellents, and sprays that could be sprayed or applied to bat nests.

[0003] Also, as a conventional repellent, Patent Document 1 discloses a structure for preventing bats from landing under the eaves. This structure is such that, under the eaves where the eaves seen from below the eaves edge form an acute corner with the exterior wall, a shielding member inclined in the opposite direction to the eaves is fixed between the eaves and the exterior wall along the longitudinal direction of the corner, and the shielding member separates the eaves and the exterior wall by the shielding member so that even if a bat clinging upside down to the exterior wall braces its front and rear legs and protrudes the lower end of its back toward the eaves, the lower end of its back does not touch the eaves, and furthermore, the shielding member is made of a plate with a smooth surface, and the upper and lower ends of the shielding member serve as attachment parts fixed to the eaves and the exterior wall, and the middle part serves as a concealing part that covers the corner, and the hanging length of the attachment part fixed to the exterior wall is longer than the height of the bat. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 2766789

[0005] However, conventional sprays, repellents, and sprays require application to the entire inner surface of the wall, which is cumbersome, for example, when the nest is in the ceiling. In addition, spraying the sprays, repellents, and sprays may drive the bats further inside.

[0006] In addition, the climbing prevention structure described in Patent Document 1 cannot be installed after bats have taken up residence. It is also necessary to wait for the bats to fly away and then install the structure after confirming that there are no bats inside the building, which is inefficient. If this is neglected, bats may be left behind or trapped inside the building. Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, an object of the present invention is to provide a device for driving out bats, which can prevent bats from being left behind or trapped inside a building, and a method for installing the same. [Means for solving the problem]

[Diagram 5] 1 is a flowchart showing a method for installing a trap for driving out bats according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described in detail with reference to Figs. 1 to 5. The bat eviction device 100 of this embodiment is used to evict bats from their nests and prevents or obstructs their entry after eviction. Note that the present invention is not limited to the following embodiment.

[0019] In the case of ordinary houses built in the Japanese style with horizontal siding on vertical trusses, depending on the type of exterior wall 1 and how the roof is handled, bats may invade the space between the exterior wall 1 and the waterproof sheet.

[0020] In addition, as shown in Figure 1, in Japanese-style houses where rafters 4 can be seen under the eaves 3, there is depth to the door panel, so bats may fly in to rest. For example, in the case of the oil bat, if there is a gap G of 10 mm or more around the vertical truss of the house or around the rafter 4 as shown in Figure 2, the oil bat will start hiding in this gap G and may even take up residence.

[0021] In Fig. 2, gap G exists between the decorative board 2 and the rafter 4. The decorative board 2 is disposed between the rafters on the front side of the door panel, and is attached to the sheathing board 5 and the eaves beam 6. The eviction device 100 is used at an access point N for bats that includes gap G. In the case of this embodiment, the access point N is the sheathing board 5 and the eaves beam 6 that sandwich gap G, and the decorative board 2 and the rafter 4 that sandwich gap G.

[0022] The driving-out device 100 includes a woven wire mesh 10, an outlet 20, linear projections 30, and an attachment portion 50. The driving-out device 100 has a size sufficient to cover the access location N.

[0023] Examples of the woven wire mesh 10 include woven wire fabric conforming to JIS G 3555 and industrial woven wire mesh conforming to JIS G 3556. The woven wire mesh 10 includes annealed iron wire woven wire mesh, galvanized iron wire woven wire mesh, and stainless steel wire wire mesh.

[0024] The woven wire mesh 10 is preferably made of stainless steel wire produced using a stainless steel wire material and a heat-resistant steel wire material containing 10.5% or more of chromium. The stainless steel wire conforms to JIS G 4309.

[0025] The woven wire netting 10 has vertical wires 12 and horizontal wires 13. The wire diameter is 0.020 mm or more and 14.0 mm or less, preferably more than 0.16 mm and 0.50 mm or less, and more preferably 0.4 mm. The wire diameter refers to the diameter of the wires of the mesh wire netting 10.

[0026] The woven wire netting 10 preferably has mesh 15 that is sufficiently finer than the target bat species in order to prevent physical intrusion of the bat species. The mesh 15 refers to the area surrounded by the vertical lines 12 and the horizontal lines 13.

[0027] For example, when the target bat is a pigeon bat, the mesh 15 preferably has an opening of 10 mm or less, more preferably 16 meshes. The opening refers to the distance between two adjacent vertical or horizontal lines 12, and the mesh refers to the number of openings per 25.4 mm.

[0028] The woven wire mesh 10 can be manufactured by a plain weave wire mesh. That is, the woven wire mesh 10 is manufactured by intersecting the vertical wires 12 and horizontal wires 13 one by one at a fixed interval. Since the access points N vary depending on the construction site, the woven wire mesh 10 is cut to a size appropriate for the construction site before use.

[0029] The woven wire netting 10 has a portion cut to form a weave gap 11. The weave gap 11 has a predetermined area. The area is formed such that the width X is equal to or larger than the mesh size of the woven wire netting 10 but smaller than the overall width of the woven wire netting 10, and the length Y is shorter than the head and body length of the target bat. The width X refers to the distance of the horizontal line 13 in a cut, missing state or in an unwoven state. The length Y refers to the distance of the vertical line 12 in a cut, missing state or in an unwoven state.

[0030] 2 shows an example of a weave deviation 11 in which some of the horizontal wires 13 have been cut and removed. In the weave deviation 11, multiple horizontal wires that exist within a length Y from one side or one horizontal wire of the woven wire mesh 10 at both ends of the width X have been cut and removed, resulting in multiple wires 31.

[0031] The exit 20 is an opening intentionally formed in the woven wire mesh 10 for the exit of bats. The exit 20 has an opening area larger than the area of ​​the mesh 15. The opening area of ​​the exit 20 is expressed as the product of the width X and the length Y. The exit 20 opens in an opening direction D, which is diagonally downward as shown in FIG. 3.

[0032] The protruding member 30 is composed of the exit 20 and a plurality of lines 31. The plurality of lines 31 are inclined, and the inclination direction of the linear protrusion 30 is parallel to the opening direction D. The linear protrusion 30 can also serve as an exit guideway for the bats in the nest.

[0033] The multiple lines 31 cover the outlet 20 in front view. Furthermore, the multiple lines 31 are inclined diagonally downward at a predetermined angle θ from the surface of the woven wire mesh 10 in side view. The angle θ is determined in relation to the opening height of the protruding member 30 described below. For example, it may be within a range of 20 degrees or more and 45 degrees or less. Furthermore, the multiple lines 31 protrude forward from the surface of the woven wire mesh 10 in bottom view, as shown in FIG. 4.

[0034] The wire 31 is an obstruction member intentionally formed at the exit 20 to prevent or hinder the entry of bats. The wire 31 is preferably a soft stainless steel wire. The tensile strength of the multiple wires 31 is 680 to 930 N / mm 2 , 610~860N / mm 2 , 580~830N / mm 2 However, the test method shall be in accordance with JIS Z 2241.

[0035] The length of the line 31 is set to be shorter than the head and body length of the target bat. For example, if the target bat is an oil bat, the length is preferably within 30 mm. The width X of the protruding member 30 on which the multiple lines 31 are arranged is available in various versions so as to be adaptable to the construction site.

[0036] Moreover, it is preferable that the linear protrusion 30 has a warp 40 on the line 31. The warp 40 refers to the longest distance from the imaginary straight line from the base 32 to the tip 33 of the line 31 to the perpendicular line to the line 31, or the part of the longest distance. Examples of the warp 40 include a lower back warp, a center warp, a tip warp, an inward warp, and a bamboo shoot warp. Moreover, the tips 33 of the multiple lines 31 may be aligned in one direction, but it is preferable that the tips 33 of each are randomly oriented in various directions, as shown in Figures 2 to 4.

[0037] The opening height of the protruding member 30 refers to the distance of a perpendicular line from the opening plane of the exit 20 to the tip 33 of the line 31, or, if a curvature 40 is present, the distance of a perpendicular line from the opening plane of the exit 20 to the curvature 40, and it is preferable that this distance is sufficient to allow the bats to exit.

[0038] For example, in the case of the target bat, the oil bat, which has a small body and high athletic ability, the opening height of the protruding member 30 is preferably within the range of 8 mm to 15 mm. If it exceeds 15 mm, it will be physically possible for the bat to enter, while if it is less than 8 mm, it will be impossible for the bat to exit, or a congestion of exiting oil bats will occur.

[0039] The mounting portion 50 is a portion of the woven wire mesh 10 for mounting to an access location N for bats. The mounting portion 50 is provided around the periphery of the weave gap 11. The mounting portion 50 is attached to the decorative board 2, the rafters 4, the sheathing board 5, and the eaves beam 6. Examples of methods for mounting the mounting portion 50 include silicone caulking, sealing, and mounting methods using screws or tackers.

[0040] Next, a construction method 200 for the driving-out device 100 will be described with reference to Fig. 6. Fig. 6 is a flow chart showing the construction method 200. The construction method 200 has steps S201 to S207.

[0041] First, in step S201, construction is started. When construction is started, it is preferable to confirm an access point N for bats at the construction site. However, it is not necessary to wait for or confirm the exit of the bats.

[0042] Next, in step S202, the woven wire mesh 10 is prepared. Since the access location N varies depending on the construction site, in step S202, the woven wire mesh 10 may be cut to a size appropriate to the construction site. In addition, the woven wire mesh 10 may be cut in step 206, or may be cut in both steps.

[0043] In step S203, cuts are made in the woven wire mesh 10 to form weave gaps 11. Specifically, multiple horizontal lines are cut in the longitudinal direction from one side of the woven wire mesh 10 by a length Y at both ends of the width X, and the multiple cut horizontal lines are removed (see FIG. 2).

[0044] In step S204, linear protrusions 30 are formed. For example, a finger is placed on the weave deviation 11, and the tip 33 of the line 31 is tilted around the base 32 of the line 31 as an axis. In this way, linear protrusions 30 consisting of outlets 20 and a plurality of tilted lines 31 are formed.

[0045] In step S205, the warp 40 is formed in the wire 31. For example, a method of applying force to the tip 33 of the wire 31 to form the warp 40, or a method of pinching the wire 31 with fingers to orient it in various directions can be used. Here, it is preferable to form the warp 40 so that the multiple wires 31 are randomly oriented in various directions.

[0046] In step S206, the mounting portion 50 is attached to the access location N. Specifically, silicone caulking or sealing is applied to the mounting portion 50, or a screw or a tacker is used. In this way, the expulsion device 100 is attached to the access location N.

[0047] In step S207, the installation of the drive-out device 100 is completed. After installation, there is no need to check for the exit of bats. If bats are inside, they will fly out from the exit 20 after installation.

[0048] As described above, the device 100 for driving out bats of this embodiment has the above-mentioned configuration, so that it is possible to prevent bats from being left behind or trapped in a building. Therefore, even if bats have taken up residence, it is possible to use the device in that location and drive them out.

[0049] That is, the access point N is covered with a woven wire mesh 10, so that bats can of It is possible to prevent entrance and exit from any location other than the exit 20. On the other hand, since the drive-out device 100 has the exit 20, the bats can exit from the exit 20. If the exit 20 opens in the opening direction D, which is diagonally downward, the bats can exit in the opening direction D.

[0050] Generally, bats fly out in the evening to catch food. It is said that bats have a homing instinct, and after flying out, they try to return to access point N.

[0051] However, the driving-out device 100 is equipped with the linear protrusions 30, and is therefore capable of preventing or obstructing the approach of bats to the access point N. The linear protrusions 30 are made up of a plurality of wires 31, and therefore the tips 33 of the plurality of wires 31 can come into contact with the approaching bats, and can act as an obstacle to approach or intrusion to prevent or obstruct the intrusion.

[0052] In addition, when the multiple wires 31 cover the exit 20 in a front view and protrude forward from the woven wire mesh 10 in a bottom view, the linear protrusions 30 can prevent entry or re-entry from the exit 20. Of course, it is also possible to prevent approaching the linear protrusions 30 or stopping to rest.

[0053] When the wires 31 have the curvature 40, the lengths of the wires 31 are different, and this allows for a wide range of approach distances and positions for bats. Also, when the tips 33 face in various directions, this allows for a wide range of approach directions for bats.

[0054] Furthermore, when the wire 31 is a soft stainless steel wire, the shape of the linear protrusions 30 can be maintained even when natural phenomena such as wind or rain occur, and deformation or swaying can be easily prevented. On the other hand, when the wire 31 is soft, the installer can easily and simply form deformations and warping 40 in the wire 31. This provides good workability.

[0055] Furthermore, if the wire 31 is soft, the bats can push the wire 31 from the inside when they exit, and it is possible to prevent the wire 31 from getting in the way of the bats' exit. On the other hand, if the tip 33 or the curve 40 gets in the way of the bats' entry, the bats cannot deform the tip 33 or the curve 40, and entry is prevented. This is effective in terms of expulsion, prevention of entry, and repelling.

[0056] Furthermore, the linear projections 30 have a tensile strength of the multiple wires 31 of 680 to 930 N / mm 2 , 610~860N / mm 2 , 580~830N / mm 2 In the case of , it has moderate viscosity, good repellency, and is easy to apply.

[0057] Furthermore, when the wire diameter of the wire 31 is more than 0.16 mm and not more than 0.50 mm, for example, 0.4 mm, the wire 31 is thin and has a certain stiffness. Therefore, the wire 31 is easy to apply, and the sharp tips 33 of the linear projections 30 have a high repellent effect.

[0058] When the exit 20 opens obliquely downward and the linear protrusions 30 are inclined along the opening direction, the bats can exit from the exit 20 along the linear protrusions 30. of It can respond to the characteristics and prevent approach or intrusion.

[0059] When the woven wire mesh 10 is made of stainless steel wire, it is possible to prevent rust from occurring. It is also resistant to deterioration over time and can withstand long-term use. In other words, it can exert its effect as a repellent for bats for a long period of time.

[0060] According to the construction method 200 of this embodiment, construction can be easily and quickly performed without checking whether bats have flown away and are not still in the building. In other words, construction can be easily and quickly performed even when bats are living in the building. Therefore, for example, there is no need to wait until evening to perform construction, or to check whether bats have flown away or are not still inside the building. Therefore, construction can be performed quickly without having to wait until nighttime.

[0061] Furthermore, the construction method 200 can be applied to construction sites that do not have a gap G. For example, construction can be performed between rafters that do not have a gap G. Construction can also be performed in Japanese-style houses where the rafters 4 are not visible under the eaves 3. When construction is performed between rafters, for example, the opening width X of the outlet 20 and the width of the linear protrusion 30 in which the multiple lines 31 are arranged can be formed within a range of 10 mm to 200 mm.

[0062] (Modifications of the invention) In addition ,Ko Devices for driving out arachnids and The present invention The configuration related to the construction method is not limited to the above embodiment, and the configuration related to the woven wire mesh, outlet, linear protrusions, warping, shape of the mounting part, and structure or each process can be appropriately changed within the scope that does not deviate from the spirit of the present invention.

The manufacturing method of the woven wire mesh is not limited to the plain weave wire mesh, and may be, for example, a twill weave wire mesh or a tatami weave wire mesh.

[0064] Also, while Fig. 2 shows a woven wire net with a square mesh, the present invention is not limited to this. The woven wire net may be of any shape as long as it can be attached to the access point of the bats, and can be adapted to suit the access point. Fig. 2 shows the woven wire net with ears, but the ears do not have to be present. The ears are the loop-shaped folded parts on the outside of the horizontal lines.

[0065] Moreover, the weave gap in the woven wire mesh is not limited to a weave gap in which a slit is made in the woven wire mesh and a part of the horizontal wire is cut and removed, and may be, for example, a state in which the horizontal wire is not woven, or a state in which the vertical wire and the horizontal wire are not woven. The weave gap may be a state in which a slit is made in the woven wire mesh and a part of the vertical wire is cut and removed, or a state in which the vertical wire is not woven. That is, the weave gap may be formed by making a slit in the woven wire mesh. The position of the slit does not have to be one side as shown in FIG. 2, but may be the other side or the center. If the slit is not located on the side, it is sufficient to cut part of the wire to make it tilted.

[0066] moreover ,Ko The trap for driving out Albatrosses is not limited to the above embodiment in which the lines are inclined obliquely downward as shown in Fig. 3. For example, the lines may be inclined in the length direction, width direction, or obliquely upward.

[0067] And again ,Ko The trap for driving out Albatrosses is not limited to one having a curved wire as in the above embodiment, and may be, for example, one having an inclined wire without a curve.

[0068] Furthermore, the access points for the bats are not limited to places including gaps between the decorative boards and the rafters, as in the above embodiment, but may be places having other gaps, or may be access points for the bats that do not have gaps.

[0069] The method of installing the trap for driving out bats according to the present invention is not limited to the above embodiment, which includes a step of forming a warp. For example, the trap may be attached to an access point for bats without forming a warp.

[0070] Furthermore, the method of installing the bat repellent device of the present invention is not limited to installation in Japanese-style houses where rafters are visible under the eaves, as in the above embodiment, but can also be installed in houses where rafters are not visible under the eaves.
