DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing birds from flying, and more particularly to a technique for preventing birds from flying to a predetermined area such as an outdoor facility.

[0002]

2. Description of the Related Art In recent years, birds such as pigeons have come to shrines, temples, station buildings, condominiums, factories, and the like, and the dung damage caused by the birds has increased rapidly. Due to this dung damage, there is a problem that the aesthetic appearance of the facility is impaired, and various diseases such as parrot disease, cryptococcosis, Newcastle disease, etc. occur through the dung, and pigeons are currently a problem. There is a problem in that it may cause allergies or severe disorders, or may transmit pathogens or parasites that may cause death.

[0003] For this reason, conventionally, birds are prevented from flying by an eyeball pattern drawn on the balloon surface (this device is hereinafter referred to as a "eyeball-type birds flying prevention device"), and birds are magnetized by permanent magnets. (Hereinafter, this device is referred to as a “magnetic bird flight prevention device”) has been devised, and these devices are installed in a predetermined area such as an outdoor facility.

[0004]

However, the eyeball-type bird flying prevention device can cause the fear of birds' eyes and temporarily prevent the bird from flying, but the change is small, so that the bird's fear is raised. The power was weak. Therefore, there is a problem in that the birds become accustomed to the eyeballs due to their learning ability, and the effect of preventing flying is reduced or eliminated.

[0005] Further, in the magnetic birds flying prevention device, the range of the magnetic field of the permanent magnet is very narrow, and the fluctuation of the magnetic field is small. Therefore, also in this case, there is a problem that the magnetic stimulus to the birds is small, and even a slight magnetic field stimulus is easily accustomed by short-term learning, and the flying prevention effect is low.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a bird flying prevention device which has a high flying prevention effect and can make it permanent.

[0007]

In order to achieve the above-mentioned object, the present invention is configured as follows.

That is, according to the first aspect of the present invention, there is provided a birds flying prevention apparatus comprising: a ring-shaped magnet, an object which transmits or reflects light, and a reflector which is made of a non-magnetic material and reflects light. They are arranged in the shape of eyes.

According to the first aspect of the present invention, a magnet,
Since the shape of the eyes is formed by an object that transmits or reflects light and a reflector made of a non-magnetic material, a so-called threatening effect can cause a bird who has seen the eye to have high fear. In addition, since the magnet is formed in a ring shape, the magnetic field is spread over a wide range, and the strong magnetic force of the magnet over a wide range can strongly disturb the sense of direction of birds. Further, the threatening effect can be further enhanced by transmission or reflection of light by the object and reflection of light by the reflector.

According to a second aspect of the present invention, in the first aspect of the present invention, the magnet is an iris of the black eye, the object is a glass sphere and is a pupil of the black eye, and the reflector is a plate shape and the white eye is a white eye. Are arranged so as to correspond to each other.

According to the second aspect of the present invention, the ring-shaped magnet is arranged corresponding to the iris of the black eye, the glass ball is arranged corresponding to the pupil of the black eye, and the reflector is arranged corresponding to the white eye. The shape will give a more threatening effect.

According to a third aspect of the present invention, in the first or second aspect, the invention is rotatably supported.

According to the third aspect of the present invention, since the birds fly prevention device is rotated by wind power or the like, the rotation causes a change in the magnetic field and a change in the transmitted light and the reflected light. It is difficult for the learning effect to work and the permanence of the flying prevention effect can be enhanced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a bird flying prevention device according to an embodiment of the present invention.

FIG. 1 is a front view showing the structure of the birds flying prevention device, FIG. 2 is a cross-sectional view taken along section line AA of FIG. 1, and FIG. 3 is a cross-sectional view taken along section line BB of FIG. It is.

The bird flying prevention device 1 of this embodiment is
Factories, warehouses, stations, houses, apartment houses, building balconies,
It is installed at a desired place where it is desired to prevent birds from flying, such as a pedestrian bridge, an arcade, and a hospital.

The birds flying prevention device 1 includes a ring-shaped permanent magnet 10 corresponding to the iris of the iris.
And a glass bulb 20 attached to the central through hole 11 of the permanent magnet 10 via the caps 40a and 40b to transmit light so as to correspond to the pupil of the black eye, and a permanent magnet to correspond to the white eye. The device includes reflectors 30a and 30b having a substantially elliptical outer shape attached to the periphery of the device 10, and a key ring 50 that rotatably supports the device 1 at an appropriate location.

The permanent magnet 10 radiates a strong magnetic force of, for example, about 1300 gauss over a wide range from the ring-shaped end face.

The caps 40a and 40b are made of a non-magnetic material such as a synthetic resin.
1, the glass ball 20 is housed in the through hole 11, and the other cap 40b is fitted into the through hole 11. Thereby, the glass sphere 20 is attached to the through hole 11 of the permanent magnet 10 in a state where a part of the circular shape is exposed.

The reflectors 30a and 30b are formed by pressing a non-magnetic material having light reflectivity, for example, SUS or aluminum, into a plurality of (four in the drawing) rivet holes 31a.
And a flat portion 32 having a substantially elliptical shape,
A stopper portion 34 having a through hole 33. Reflector 3
The permanent magnet 10 is fitted between the two stopper portions 34a and 30b, and the rivet holes 31a to 31d are stopped by the rivets 60a to 60d. Thereby, the reflection plate 30a,
30 b is attached around the permanent magnet 10. In this attached state, a part of the end face of the permanent magnet 10 is annularly exposed.

Note that, above the reflection plates 30a and 30b,
The fastener 70 is riveted and this fastener 70
The end of the key ring 50 is attached. This key ring 5
Reference numeral 0 denotes a rotatable support for the reflectors 30a, 30b on which the glass sphere 20, the permanent magnet 10, and the like are assembled.
b is rotated or rocked.

According to such a bird flying prevention device 1,
Permanent magnet 10, glass ball 20, reflectors 30a, 30
b constitutes an eyeball shape. For this reason, it is possible to exert a threatening effect that a high fear can be caused to the birds that have seen the birds.

Further, since the birds flying prevention device 1 of this embodiment is rotatably supported by the key ring 50, it rotates or swings due to the wind, whereby the magnetic field fluctuates due to the permanent magnet 10. With
Fluctuations in transmitted light and reflected light by the glass sphere 20 and the reflectors 30a and 30b occur, which increases the threatening effect, makes it difficult for birds to learn, works less with eyeballs, and increases the permanence of the flying prevention effect. Can be.

In particular, the light hitting the glass sphere 20 is prism-like and is diffusely reflected in a wide direction and changes as if the pupil glowed, while the light hitting the reflectors 30a and 30b was complicated. Moreover, the light is irregularly reflected in a wide direction, and changes as if the white eyes glowed. Therefore, the fear-inducing ability, that is, the threatening effect can be further enhanced.

In addition, the glass bulb 20 and the cap 40
a, 40b and the reflectors 30a, 30b are formed of a non-magnetic material. Therefore, the magnetic force of the permanent magnet 10 is reduced by the glass sphere 20, the caps 40a and 40b, and the reflection plates 30a and 30a.
It is not absorbed by b. Further, since the permanent magnet 10 is formed in a ring shape, it can be spread over a wide range. Therefore, the bird's sense of direction can be strongly disturbed by the wide range of strong magnetic force of the permanent magnet 10. Therefore, the learning ability of the birds is difficult to work, and the familiarity with the magnetic fluctuation is reduced in combination with the fear-raising power for the eyeball.

(Other Embodiments) The birds flying prevention apparatus according to the present invention has been described based on the embodiments. However, it goes without saying that the contents of the present invention are not limited to the above embodiments. Yes, the following modifications are conceivable.

In the above-described embodiment, the glass sphere 20 which transmits light is used. However, the glass sphere 20 may be coated with a reflective material so as to have light reflectivity. You may make it reflective.

A wind receiver may be provided at an appropriate location, for example, at the periphery of the reflector so as to rotate or swing by a slight wind force.

Further, a driving source such as a motor may be connected to rotate the reflection plates 30a and 30b.

In the above embodiment, the permanent magnet 10 is used as the iris of the black eye, the glass ball 20 is used as the pupil, and the reflectors 30a and 30a are used.
Although b corresponds to each white eye, the present invention is not limited to this, and may be any arrangement that corresponds to the shape of the eyes.

[0031]

As described above, according to the bird flight prevention device of the present invention, the shape of the eyes is constituted by the magnet, the object that transmits or reflects light, and the reflector made of a non-magnetic material. The threatening effect can cause the birds who see it to have high fear. In addition, since the magnet is formed in a ring shape, the magnetic field is spread over a wide range, and the strong magnetic force of the magnet over a wide range can strongly disturb the sense of direction of birds. Further, the threatening effect can be further enhanced by transmission or reflection of light by the object and reflection of light by the reflector.

Further, since it is rotatably supported, the bird fly prevention device is rotated by wind force or the like, and a fluctuation of a magnetic field and a fluctuation of transmitted light and reflected light are caused. It is difficult to work and can increase the durability of the flying prevention effect.
