Accordingly, when the artificial nest 1 is attached to a steel tower or a power distribution post, a bird to build a nest can be guided to the artificial nest attached to a safe place to prevent earth fault, short-circuiting failure, etc., caused by collapse of the nest. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a bird's artificial nest installed in a structure such as a steel tower and a distribution pole.

  Conventionally, it has been a problem that birds nest on steel towers and distribution poles. When the bird's nest collapses, there is a risk that the collapsed nest material may cause a ground fault that touches the wires and the aggregates of the tower and distribution poles, or a short-circuit accident that touches two different types of wires. .

  As a countermeasure against such an accident, a nesting cage was previously installed on a steel tower and a power distribution pole in a safe place even if a bird built a nest, and the bird was guided to the nesting cage for nesting.

  However, because the conventional nesting cage 100 has a strong artificial color such as a cup-shaped mesh material as shown in FIG. 4, the probability of birds nesting in this conventional nesting cage 100 is low. It was. Therefore, even if the nesting cage 100 is installed on a steel tower and a power distribution pole, birds will nest in places other than the place where the nesting cage 100 is installed, so that the above-mentioned ground fault and short circuit accident can be effectively prevented. There was concern that could not.

  Therefore, an object of the present invention is to solve the above-described problems and to provide an artificial nest having a high probability that a bird will nest.

  The artificial nest according to claim 1, which is an invention made to solve the above-described problems, has a bottom portion and a side portion rising from a peripheral portion of the bottom portion by randomly bending a long nest material. It is characterized by being formed in a substantially bowl shape.

  Conventional nesting baskets are geometrically patterned with straight lines and curves, and appear artificial, so it is conceivable that birds have avoided nesting, but the artificial nest of the present invention is a long nest material Can be bent at random and formed into a substantially hook-like shape, which makes it look natural, increasing the probability of birds nesting.

  Therefore, if this artificial nest is attached to a steel tower and distribution pole, it is possible to prevent birds from nesting in places other than where the artificial nest is installed. It is possible to prevent a ground fault or a short-circuit accident that occurs with a higher probability than when a conventional nesting basket is attached.

  In addition, when this artificial nest is used, it is possible to guide the bird to a safe place on the steel tower and the distribution pole so that the bird is not electrocuted and nesting.

  Next, as described in claim 2, with respect to the bottom portion, adjacent nest members are fixed to each other, and a plurality of side surface portions are formed along the peripheral portion of the bottom portion, and upward from the peripheral portion of the bottom portion. It may be formed in a shape including a plurality of base portions that rise up and at least one braided portion that can be braided into the base portion along the peripheral portion of the bottom portion.

  In the conventional nesting cage, the shape of the nesting cage is fixed in order to prevent the deformation of the shape. However, in the invention described in claim 2, if several bases are selected from a plurality of bases and the braided part is knitted into the base, the size and shape of the nest can be adjusted according to the taste and body shape of the bird. It can be changed freely.

  Therefore, if this artificial nest is attached to a steel tower and distribution pole, it is possible to prevent birds from nesting in places other than where the artificial nest is installed. It is possible to prevent a ground fault or a short-circuit accident that occurs with a higher probability than when a conventional nesting basket is attached.

  The artificial nest described above may be formed of a plurality of nest materials. However, as described in claim 3, it is needless to say that the artificial nest may be formed of a single long nest material.

Embodiments to which the present invention is applied will be described below.
[First Embodiment]
Here, FIGS. 1 and 2 are perspective views of the artificial nest of the first embodiment, FIG. 1 is a diagram for explaining a state in which the braided portion is knitted in the base portion, and FIG. 2 is a diagram showing the braided portion from the base portion. It is a figure for demonstrating the state removed.

  As shown in FIG. 1, the artificial nest 1 of the present embodiment has a substantially bowl shape having a bottom portion 2 and a side portion 3 rising from a peripheral portion of the bottom portion 2 by bending a long nest material 10 at random. Is formed.

  Further, in the bottom portion 2, adjacent nest members 10 are fixed to each other.

  Further, the side surface portion 3 is formed in a plurality along the peripheral portion of the bottom portion 2, has a plurality of base portions 30 rising upward from the peripheral portion of the bottom portion 2, and has a base portion 30 along the peripheral portion of the bottom portion 2. And two knitting portions 32 that can be knitted with respect to each other.

  Specifically, the artificial nest 1 is created as follows.

  The nest material 10 made of polyethylene resin is sequentially injected and sent out on the surface of the mold formed in a substantially truncated cone shape, and the sent nest material 10 is sent out so as to be bent at random on the die.

  At this time, with respect to the bottom portion 2, the nest material 10 is placed on the mold so that a plurality of base portions 30 are raised from the bottom portion 2 while the nest material 10 is closely spaced. Further, the nest material 10 is placed on the mold so that a knitted portion 32 for knitting into the base 30 is formed along the periphery of the bottom portion 2.

  Then, when the injection of the nest material 10 is completed, the nest material 10 forming the bottom 2 of the nest is lightly crushed so as to adhere to each other and cooled for a predetermined time.

  Finally, as shown in FIG. 2, since there is a portion where the base 30 and the braided portion 32 are bonded, the artificial nest 1 of this embodiment is completed by peeling it off.

  In the artificial nest 1 of this embodiment manufactured in this way, the bottom portion 2 is fixed to the adjacent nest materials, and the side portion 3 is freely knitted by the braided portion 32 with respect to the plurality of base portions 30. Be able to.

  Therefore, in the artificial nest 1 of the present embodiment, the bird can freely change the size and shape of the nest according to their preference and body shape, so if this artificial nest 1 is attached to a steel tower and a distribution pole, this Compared to the case where a conventional nesting cage with no freedom is attached, the probability that a bird can be guided to a safe place where the artificial nest 1 is installed is increased. This increases the probability that the bird will nest at the place where the artificial nest 1 is installed. Compared to the case of using a conventional nesting cage, the bird will nest at a place other than the place where the artificial nest 1 is installed. Can be prevented with high probability.

  Further, the artificial nest 1 of the present embodiment has a natural shape in which the long nest material 10 is randomly curved, and is also a natural shape in that the braided portion 32 can be knitted into the base portion 30. Compared to an artificial one such as a conventional nesting cage, the probability of birds nesting in this artificial nest 1 is increased.

As a result, when this artificial nest 1 is used, there is a higher probability of ground faults and short circuit accidents caused by the collapse of the nests made by birds on steel towers and distribution poles compared to the case where conventional nesting cages are attached. Can be prevented.
[Second Embodiment]
Next, a second embodiment will be described.

  Here, FIG. 3 is a perspective view of the artificial nest of the second embodiment.

  In the following description, the same components as those in the first embodiment will be described using the same reference numerals.

  As shown in FIG. 3, the artificial nest 1 of the present embodiment has a substantially bowl shape having a bottom portion 2 and a side portion 3 rising from a peripheral portion of the bottom portion 2 by bending a long nest material 10 at random. Is formed.

  Specifically, the artificial nest 1 is created as follows.

  The nest material 10 made of polyethylene resin is sequentially injected and sent out on the surface of the mold formed in a substantially truncated cone shape, and the sent nest material 10 is sent out so as to be bent at random on the die.

  At this time, with respect to the bottom portion 2, the nest material 10 is placed on the mold so that a plurality of base portions 30 are raised from the bottom portion 2 while the nest material 10 is closely spaced. Further, the nest material 10 is placed on the mold so that the braided portion 32 is formed along the periphery of the bottom portion 2 while sewing between the base portions 30.

  Then, after the injection of the nest material 10 is completed, the entire nest material 10 is lightly crushed so that the nest material 10 is adhered to each other, and cooled for a predetermined time, whereby the artificial nest 1 of the present embodiment is completed.

  The artificial nest 1 of the present embodiment thus manufactured has a natural shape in which a long nest material 10 is randomly bent, and a natural shape in which a braided portion 32 is knitted into the base 30. Therefore, the probability that a bird nests in this artificial nest 1 is increased compared to an artificial one such as a conventional nesting cage.

As a result, when this artificial nest 1 is used, there is a higher probability of ground faults and short circuit accidents caused by the collapse of the nests made by birds on steel towers and distribution poles compared to the case where conventional nesting cages are attached. Can be prevented.
(Other embodiments)
In the first embodiment described above, the artificial nest 1 having two braided portions 32 has been described, but it is needless to say that one braided portion 32 may be formed or three or more braided portions 32 may be formed.

  Moreover, in the said embodiment, although the polyethylene-type resin was used as the nest material 10, what kind of thing may be used if it is a flexible insulating plastic.

  The present invention is not limited to the above-described embodiment as long as it matches the gist of the invention described in the claims.

It is a perspective view of the artificial nest of 1st Embodiment, and is a figure for demonstrating the state which knit the braided part in the base. It is a perspective view of the artificial nest of 1st Embodiment, and is a figure for demonstrating the state which removed the braided part from the base. It is a perspective view of the artificial nest of 2nd Embodiment. It is a perspective view of the conventional nesting basket.
