Description

The present invention is a bird control device stretched around a bird damage prevention target area in order to prevent birds from invading the bird damage prevention target area, and the bird damage prevention device is used to reach the bird damage prevention target area. Regarding bird control methods to prevent the invasion of birds.

In order to prevent bird damage such as eating crops and dropping feces on buildings and automobiles, bird damage control equipment is installed in places where birds are to be prevented from invading (bird damage prevention target areas). As a bird damage control device, a tape having a special pattern (see, for example, Patent Document 1) and a tape that reflects light (see, for example, Patent Document 2) are known. Although this type of bird pest control device was relatively easy to install, it could not always be said to have an excellent bird control effect. In particular, for smart birds with high learning ability, there is a risk that the bird control effect will not be achieved after a certain period of time has passed since the installation.

Further, as a bird control device, one having a driving portion (see, for example, Patent Document 3) is also known. It is hard to say that this kind of bird control device is also excellent in controlling smart birds. Further, a bird control device having a driving portion is often expensive, and has a drawback that the installation cost becomes enormous when the area of the bird damage prevention target portion is large. In addition, the bird control device having a driving part has a drawback that it is difficult for elderly people and the like to install it by themselves, and it is difficult for farmers who are aging in recent years to use it.

The present invention has been made to solve the above problems, and is to provide a bird control device capable of exhibiting an excellent bird control effect at a low cost even though it is easy to install. .. It is also an object of the present invention to provide a bird control method for preventing birds from invading a bird damage prevention target site by using this bird control device.

The above issues are
It is a bird control device that is stretched around the bird damage prevention target area to prevent birds from invading the bird damage prevention target area.
Warp and weft stretched in the horizontal direction,
Multiple warps that hang down from the weft at predetermined intervals,
It is solved by providing a bird pest control device characterized by being composed of.

As described above, the bird control device of the present invention has a simple structure including a warp and a plurality of warps, and thus can be provided at a low price. Further, the bird control device of the present invention can be installed by tying the end of the warp and weft to the pillar material, and the installation is very easy. Further, the bird control device of the present invention has an excellent bird control effect.

This is because the inventor has tried various measures to prevent bird damage, but birds dislike hitting something on their wings when they are flying, and something hits their wings. At that time, he quickly flew away from the place and discovered that he had a habit of never returning to the surrounding area. In this regard, we thought that if the feathers of birds hit the hanging warp threads, birds would not be able to enter the bird damage prevention target area, and we developed the bird control device of the present invention and tested its effect. This is because an excellent bird control effect was confirmed. Further, in the bird control device of the present invention, the warp is only hung from the weft, and the lower end of the warp is in a free state, so that there is no risk of unnecessarily damaging the bird that hits the warp. It has become.

In the bird control device of the present invention, the thickness of the weft and the warp varies depending on the material and the like, and is not particularly limited. However, if the weft and the warp are made too thin, the warp and the warp may be easily broken, and it may be difficult to impart the necessary strength to the weft and the warp. Therefore, the diameter of the weft and the warp is preferably 0.01 mm or more. The diameter of the weft and the warp is more preferably 0.05 mm or more, and further preferably 0.1 mm or more.

On the other hand, if the wefts and warps are made too thick, the birds can easily notice their existence, and the birds may avoid the wefts and warps and invade the bird damage prevention target portion. In other words, it is presumed that the above-mentioned habits of birds will be best exerted by those who cannot understand what hits their wings (those who surprised birds), and wefts and warps. If it stands out, it may be difficult for the above habits to be exhibited. Therefore, the diameter of the weft and the warp is preferably 1 mm or less. The diameter of the weft and the warp is more preferably 0.7 mm or less, and further preferably 0.5 mm or less.

In the bird control device of the present invention, the materials of the weft and the warp are not particularly limited. Examples of the materials for the weft and the warp include synthetic resin filaments and natural fiber yarns. As the synthetic resin filament, for example, a single-line synthetic resin fiber such as nylon or fluorocarbon used for fishing line (Tegus), a knitting thread called a PE line having higher strength, or the like can be preferably used. Further, as the natural fiber yarn, cotton yarn or the like used for octopus yarn or the like can be preferably used. The color of the weft and the warp is not particularly limited, but is preferably transparent, green, black, or the like. By making the weft and the warp such a color, it becomes possible for birds to make it difficult for birds to notice the existence of the bird pest control device of the present invention.

In the bird control tool of the present invention, the interval between the warps varies depending on the type (body length) of the bird to be controlled, and is not particularly limited. When trying to control relatively small birds such as sparrows and swallows, the warp spacing is set narrow. However, if the intervals between the warp threads are too narrow, the warp threads may become conspicuous. Therefore, the interval between the warps is preferably 1 cm or more. The warp spacing is more preferably 5 cm or more, and even more preferably 10 cm or more.

On the other hand, when controlling relatively large birds such as crows, the warp spacing can be set wide. However, if the interval between the warps is too wide, the bird may be able to invade the bird damage prevention target portion without the warps hitting the feathers of the bird. Therefore, the interval between the warps is preferably 50 cm or less. The interval between the warps is more preferably 40 cm or less, and further preferably 30 cm or less.

In the bird control device of the present invention, the hanging length of the warp (the length of the portion hanging from the weft; the same applies hereinafter) is not particularly limited. However, if the hanging length of the warp is made too short, the bird may be able to invade the bird damage prevention target portion without the warp hitting the feather of the bird. Therefore, the hanging length of the warp is preferably 50 cm or more. The hanging length of the warp is more preferably 100 cm or more, and further preferably 120 cm or more.

On the other hand, if the hanging length of the warp is too long, not only the warp is easily entangled when the bird pest control device is stored, but also the installation of the bird pest control device may be difficult. Therefore, the hanging length of the warp is preferably 3 m or less. The hanging length of the warp is more preferably 2.5 m or less, and further preferably 2 m or less.

In the bird control device of the present invention, the method of fixing the upper end portion of the warp to the weft is not particularly limited. Examples of the method for fixing the upper end portion of the warp to the weft include binding, adhesion, welding and the like. However, the fixing method by binding is troublesome when mass-producing bird pest control equipment. Therefore, in the case of mass production of bird control equipment, it is preferable to adopt adhesion or welding as a method for fixing the upper end portion of the warp to the weft. As a method by adhesion, a method of applying an adhesive to the joint portion between the weft and the warp and solidifying is exemplified, and as a method by welding, a molten resin is applied to the joint portion between the weft and the warp. Examples thereof include a method of solidifying and a method of melting the warp or weft itself by heat and then fixing the warp and weft.

When the bird control device of the present invention described above is stretched around the bird damage prevention target portion, it becomes possible to prevent the invasion of birds into the bird damage prevention target location. It is preferable that the bird damage control device of the present invention is stretched so as to surround the bird damage prevention target portion. Further, the bird pest control device of the present invention may be laid in a single layer at the same height, but the bird pest control device is multiplexed (multi-stage) so that one bird control device and another bird control device have different heights. ) Is also preferable. This makes it difficult for birds to enter the bird damage prevention target area without the warps touching the wings, and it becomes possible to further enhance the bird damage prevention effect.

As described above, according to the present invention, it is possible to provide a bird control device capable of exhibiting an excellent bird control effect at a low cost even though it is easy to install. It is also possible to provide a bird control method for preventing birds from invading a bird damage prevention target site by using this bird control device.

It is a figure which showed the state which stretched the bird control device of this invention in a multi-stage. It is a figure which showed the bird control device of this invention. It is a figure which showed an example of the storage form of the bird control device of this invention. It is a figure which showed other example of the storage form of the bird control device of this invention.

A preferred embodiment of the bird control device of the present invention will be described more specifically with reference to the drawings. FIG. 1 is a diagram showing a state in which the bird control tool 10 of the present invention is stretched around a bird damage prevention target portion 50. As shown in FIG. 1, the bird control tool 10 is stretched around the bird damage prevention target location 50 for the purpose of preventing the invasion of birds into the bird damage prevention target location 50. The bird control device 10 is composed of a weft 11 stretched in a substantially horizontal direction and a plurality of warps 12 hanging from the weft 11 at predetermined intervals.

As already mentioned, birds are reluctant to hit their wings when they are flying, and when something hits their wings, they immediately fly away from the place and never return to the surrounding area. The bird control tool 10 of the present invention makes the warp threads 12 touch the wings of birds to prevent birds from invading the bird damage prevention target location 50 (temporarily, the bird damage prevention target location). Even if it invades 50, it will fly away quickly from that place) to prevent bird damage at the bird damage prevention target location 50.

The lower end of the warp 12 of the bird control tool 10 may be fixed to a warp (not shown) different from the upper weft 11, but in this case, the birds may be caught in the warp 11 and damage the birds. There is. Therefore, in the present embodiment, the lower end portion of the warp 12 is a free end that is not fixed to other members or the like, so that the birds that touch the warp 12 are not injured unnecessarily. However, if the lower end of the warp 12 is a free end, the warp 12 may flutter and float due to wind or the like, making it difficult for the warp 12 to touch the feathers of birds, or making it easier for the warp 12 to get entangled. Therefore, a weight portion can be fixed to the lower end portion of each warp thread 12. The weight portion may be provided by fixing a member different from the warp thread 12, but it may also be provided by melting the lower end portion of the warp thread 12 by heat or the like to form a lump and solidifying it.

By the way, in FIG. 1, a field is illustrated as a bird damage prevention target location 50, but the bird damage prevention target location 50 is not particularly limited as long as it is necessary to prevent the invasion of birds, and is not particularly limited to a building or a parking lot. It can also be a place other than a field, such as a parking lot or a garden. Further, in FIG. 1, the bird control tool 10 is stretched by connecting the weft 11 of the bird control tool 10 to the upper part of the stake 20 erected around the bird damage prevention target portion 50 (field). However, if there are trees, buildings, or the like around the bird damage prevention target portion 50, the weft 11 of the bird control tool 10 may be tied to the trees, buildings, or the like.

Further, in FIG. 1, the bird control tool 10 is stretched so as to surround the entire circumference of the bird damage prevention target location 50, but the bird control tool 10 does not necessarily have the bird damage prevention target location 50 all around. It is not necessary to stretch it so as to surround it. If there are circumstances such as a limited invasion direction of birds, it is possible to install the bird control device 10 only in that direction. Furthermore, in FIG. 1, the bird pest control device 10 is stretched in a single layer at the same height, but as shown in FIG. 2, the height of one bird pest control tool 10 and that of the other bird pest control device 10 are different. It is also preferable to install the bird pest control device 10 in multiple stages (multi-stage) so as to be. FIG. 2 is a diagram showing a state in which the bird control device 10 of the present invention is stretched in two stages (multi-stage). This makes it difficult for birds to enter the bird damage prevention target portion without the warp 12 touching the wings, and it becomes possible to further enhance the bird damage prevention effect. The bird control device 10 can be installed in three or more stages such as three stages or four stages. This makes it possible to further enhance the bird damage prevention effect.

As described above, the bird control device 10 of the present invention is composed of a weft 11 stretched in a substantially horizontal direction and a plurality of warps 12 hanging from the weft 11. FIG. 3 is a diagram showing the bird control device 10 of the present invention. The weft 11 and the warp 12 in the bird control device 10 may be formed of different materials, but in the present embodiment, they are formed of the same material. Specifically, the weft 11 and the warp 12 are fishing lines (tegus) made of synthetic resin filaments. The diameters of the weft 11 and the warp 12 are about 0.2 to 0.3 mm, and their colors are transparent. By forming the weft 11 and the warp 12 with the transparent Tegs in this way, it is possible to make the weft 11 and the warp 12 less noticeable while being hard to break and having excellent strength. Further, since the Tegs has a certain degree of elasticity while having flexibility, if the warp lines 12 are formed by the Tegs, it is possible to make it difficult for the adjacent warp threads 12 to be entangled.

As a method of fixing the upper end portion of the warp thread 12 to the weft thread 11, as described above, binding, adhesion, welding, or the like is exemplified. In this embodiment, as shown in FIG. 3, the upper end portion of the warp thread 12 is fixed (welded) to the weft thread 11 by applying the molten binding resin 13 to the joint portion between the weft thread 11 and the warp thread 12 and solidifying the bonded portion. )is doing.

As described above, the distance W (FIG. 3) between the adjacent warp threads 12 is preferably in the range of about 1 to 50 cm, but in the present embodiment, it is set to about 20 cm. This not only makes the presence of the warp 12 inconspicuous, but also makes it easier for the feathers of various types of birds, from small birds to large birds, to come into contact with the warp 12, expanding the use of the bird control device 10. Is possible. Further, the hanging length L (FIG. 3) of the warp 12 is preferably in the range of 50 cm to 3 m as described above, but in the present embodiment, it is set to about 1.5 m. As a result, it is possible to achieve an excellent bird damage prevention effect while making the bird control device 10 easy to store and easy to install.

By the way, since the bird control device 10 of the present invention has a structure in which a plurality of warps 12 are hung down, there is a possibility that the warps 12 may be entangled during storage or installation. The entanglement of the warp 12 can be prevented by devising the storage form of the bird pest control device 10 as follows.

FIG. 4 is a diagram showing an example of a storage form of the bird control device 10 of the present invention. In the example shown in FIG. 4, the bird control tool 10 is housed by winding a sheet 30 along with the bird control tool 10 in a roll shape. By adopting the bird control tool 10 in the storage form shown in FIG. 4, it is possible to prevent the warp 12 from being entangled during the transportation, sale, or installation of the bird control tool 10. When installing the bird control tool 10, the bird control tool 10 can be taken out without entwining the warp 12 by feeding out the bird control tool 10 together with the sheet 30.

The bird control device 10 in the storage form shown in FIG. 4 has a pair of upper and lower wefts 11 arranged substantially parallel to each other at predetermined intervals in the vertical direction, and a lower weft 11 having an upper end fixed to the upper weft 11. After winding the raw material of the bird control tool 10 composed of a plurality of warps 12 having a fixed lower end portion along the sheet 30, the wound body is cut at the middle portion in the vertical direction. By doing so, two can be obtained by one manufacturing process. The surface of the sheet 30 on the side along which the warp 12 is placed may be a lightly bonded surface so that the warp 12 is lightly adhered.

FIG. 5 is a diagram showing another example of the storage form of the bird control device 10 of the present invention. In the example shown in FIG. 5, the bird control tool 10 is housed in a storage tool 40 composed of a strip-shaped base material 41 and a pair of left and right protrusions 42 erected forward from the upper part of the base material 41. .. That is, the bird control tool 10 is housed by hanging the weft 11 of the bird control tool 10 around the pair of left and right protrusions 42 in the shape of an "8". By adopting the bird control tool 10 in the storage form shown in FIG. 5, it is possible to prevent the warp 12 from being entangled when the bird control tool 10 is installed. When installing the bird control tool 10, by feeding out the weft 11 from the tip end side of the protrusion 42, the bird control tool 10 can be taken out without entwining the warp thread 12.

Further, as shown in FIG. 5, by storing the bird control tool 10 stored in the storage tool 40 as it is in a container (not shown) such as a box or a bag, the bird control tool 10 can be transported or sold. At times, it is also possible to prevent the warp 12 from getting entangled.
