Description

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 such as pigeons from flying to prevent feces and other damages caused by the birds.

[0002]

2. Description of the Related Art Recently, many pigeons are inhabiting in various places, and many pigeons are seen especially in parks and shrines and temples. Pigeons are a symbol of peace, and because they are cute, they are popular with everyone and are very popular with children. However, this pigeon also has some harmful parts. This is because the excrement of feces pollutes various places and spoils the appearance, and the feces are acidic, which causes corrosion of metal parts. It may also be a source of infection of various pathogenic bacteria (parrot disease, etc.). Besides, not only damaging feces but also screaming in the residential area disturbs the sleep and is harmful.

Various measures have been implemented so far as means for preventing the harmful pigeons from flying. This can be achieved by installing needles, nets, etc., to prevent the pigeons from flying directly, by installing false eyeballs, causing the pigeons to scare them away, or by using ultrasound with a wavelength that the pigeons do not like. Numerous ideas have been devised and put into practice, such as a method of generating a sound to prevent a pigeon from flying, a method of installing a substance that emits an odor that hates a pigeon, and a method of keeping it away. However,
None of these methods was able to obtain an absolute effect.

Therefore, based on the theory that the homing property of pigeons is related to the earth's magnetic field, a device was devised to prevent the pigeons from flying by locally generating an abnormal magnetic field.
It has been implemented. In the case of the device for preventing bird damage, as an example, in the case of the device for preventing bird damage, S-pole and N of one magnet body are used.
It is intended to prevent birds by generating a fluctuating magnetic field by rotating by using the natural wind around the middle part of the pole as an axis. As a next example, the S pole and N pole of one magnet body are also used. By using a motor to rotate the middle part of the pole as an axis, a fluctuating magnetic field is generated to try to protect the bird. In addition,
In the 1080090 "bird-preventing device using fluctuating magnetic field" and the actual Kaihei 1-146881 "pigeon flying prevention device", the magnet body is fixed to the tension wire, and it is installed at a predetermined position, and the bird raises itself. By fluctuating the magnetic field by the wind, it tries to prevent birds. Next, the actual Kaihei 4-2
The 8080 "birds flying prevention device" is intended to prevent birds by generating a fluctuating magnetic field by rotating a plurality of magnet bodies attached to a propeller using wind.

Each of these methods also has advantages and disadvantages. In other words, in Japanese Utility Model Laid-Open No. 1-63386, "A device for preventing bird harm" controls the movement of one magnet body, and the control method is to use natural wind, and there is no wind to some extent. Sometimes it does nothing.
It is also an inefficient method of moving one magnet body with one motor. Moreover, the rotation of the magnet body is limited to the shape of the magnet body, and the range of the fluctuating magnetic field is very small. In the actual Kaihei 1-108090 "bird-preventing device using fluctuating magnetic field" and the actual Kaihei 1-146881 "pigeon fly-prevention device", the wind generated by the bird itself is used, and its wind force is also small, and Since it requires a means of connecting with a string, it is troublesome and the effect cannot be said to be sufficiently exerted. In Japanese Utility Model Laid-Open No. 4-28080 "Bird flying prevention device", since the former two are one magnet body, a plurality of them are moved at the same time. However, this method also uses a considerable amount of wind, does not function at all when there is no wind, the position of the fluctuating magnetic field depends on the wind direction even if there is wind, it is one-sided, there is a certain direction This is only a part of the effect, and is not fully effective.

[0006]

Therefore, according to the present invention,
The instability of having to take advantage of considerable wind, as seen so far, is to be solved as described below.

[0007]

SUMMARY OF THE INVENTION In the present invention, the above object is to provide a bird flying prevention device in which a permanent magnet is supported at one end of a spring member and the other end of the spring member is fixed to a fixing base. Solve.

An excellent effect can be brought about by disposing a plurality of bird flying prevention devices thus constructed at intervals such that the magnetic forces of the permanent magnets of the respective devices interfere with each other.

[0009]

The bird flying prevention device composed of the above-mentioned means has a simple structure in which the permanent magnet is supported at one end of the spring material and the other end of the spring material is fixed to the fixing base, so that a slight disturbance such as vibration or wind Easily swings the permanent magnet in various directions,
Generate a fluctuating magnetic field.

If a plurality of the bird flying prevention devices are installed at intervals such that the magnetic forces of the permanent magnets of the respective devices interfere with each other, when the permanent magnets of one device swing due to disturbance or force, the permanent magnets of the respective devices will be The magnetic fields fluctuate as they attract or repel and interfere with each other.

[0011]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a bird flying prevention device. The permanent magnet 1 is fixedly supported by inserting one end of the spring material 2 into a spring material 2 formed of a coil spring, and the spring material 2 is abutted and fixed to a fixing base 3 to form a bird flying prevention device as a whole.

FIG. 2 is a perspective view showing another embodiment of a bird flying prevention device. In this embodiment, a spring material 2 in which a linear spring 2b is inserted inside a coil spring 2a in which a coil diameter is changed from top to bottom in a conical shape and is combined, is interposed between a permanent magnet 1 and a fixed base 3. The permanent magnet 1 has a spring member 2
The spring member 2 is fixed to one end of the spring member 2 and is fixed to the fixing base 3 to form a bird flying prevention device as a whole.

Here, the shape of the permanent magnet 1 does not have to be specified, and plate-shaped, rod-shaped, spherical, disk-shaped, etc. may be determined in consideration of the relationship with the spring material, and the spring material 2 The shape of is also not limited, and may be determined by considering the size and weight of the permanent magnet, the direction of deformation, the height dimension, etc., alone or in combination with coil springs, linear springs, leaf springs, etc. Good.

The fixing table 3 is provided with a bolt hole 3a in the fixing table 3 as shown in FIG. 3 can be attached mechanically, or as shown in FIG. 3B, a magnet 5 is provided on the lower surface of the fixing base 3 so that it can be easily attached to and detached from the iron plate portion C. As described above, it is preferable that the fixing base 3 is equipped with the hose band 6 so that the fixing base 3 can be installed by being wound around the pipe body D or the like.

The bird flying prevention device constructed as described above is installed alone or in plural at a predetermined place.

As a method of setting the permanent magnets of each of the plurality of bird flying prevention devices so that the permanent magnets can swing effectively, the devices are arranged so that the magnetic forces of the permanent magnets of each device interfere with each other. Good to deploy. By the way, Figure 4 (a) (b)
As shown in (c) and (d), the magnets are arranged at regular intervals in consideration of the magnetization direction and magnetic force. (A) is arranged at intervals in the direction in which magnetic force repels spherical permanent magnets, (B) is arranged at intervals in the direction in which spherical permanent magnets are attracted, and (C) is a direction in which rectangular permanent magnets are repelled. (D) is an example in which the magnets are arranged at intervals in a direction in which a rectangular solid permanent magnet is attracted.

Further, since the bird flying prevention device is individually independent, a plurality of birds flying prevention devices can be freely installed according to the situation of the site.

As shown in, an intensive siege deployment is possible. Again 3
Dimensional deployment is also easy.

[0018]

As described above, the present invention has the following effects. In claim 1, the bird flying prevention device has a structure in which the permanent magnet is supported at one end of the spring member and the other end of the spring member is fixed to the fixing base. Due to the action of the weight and the spring material, the permanent magnet oscillates due to a disturbance such as a slight vibration, wind, or flying of a bird, so that a fluctuating magnetic field can be generated. Further, when a plurality of the devices are installed, each device is an independent device, so that any device can be installed depending on the situation of the site.

In the second aspect of the present invention, when a plurality of the devices are installed, the permanent magnets of the devices are arranged so that the magnetic forces interfere with each other. Therefore, one permanent magnet oscillates by disturbance or by force. However, the permanent magnets of the devices interfere with each other in the directions of attraction or repulsion, the magnetic field fluctuates, and the fluctuating magnetic field prevents birds from flying.
