Abstract

PURPOSE: To provide the subject device capable of preventing birds such as pigeons from coming flying, designed to shakably hold magnets floated by the repulsive force between the identical poles and continue to generate fluctuating magnetic field for a long time. CONSTITUTION: Plural disklike magnets 1, 1 in such a state as to lie floated by the repulsive force between the identical poles are held by threading a stem shaft 2 through the respective shaft holes 1a of the magnets. The respective inner diameters of the magnets are such as to be shakable for them, and the magnets shake in a floating state even by slight wind pressure due to birds' coming flying or slight vibrations of the magnets due to the passage of e.g. vehicles, thus generating fluctuating magnetic field.

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. That is, in the actual Kaihei 1-63386 "device for preventing bird damage", the movement of one magnet body is controlled, and the control method is also the method of the present application in which natural wind is used. When there is no, it does not function at all.
Also, it is 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 "dove-flying prevention device", it is a method of the present invention in which the wind generated by the bird itself is used. Since the wind power is also small, it cannot be said that the effect is fully exerted. In the actual Kaihei 4-28080 "bird flying prevention device", while the former two are one magnet body, a plurality of them are simultaneously moved, so that it can be said that it is efficient in that respect. However, if there is no wind above a certain level, it does not function sufficiently, and even if there is wind, the position of the fluctuating magnetic field depends on the wind direction and is one-sided, and it is an effect of only a certain part of a certain direction. It cannot be said to be effective.

[0006]

Therefore, according to the present invention,
As will be seen so far, the following points are intended to solve the drawbacks of utilizing a certain amount of wind or individually utilizing a power source such as a motor.

[0007]

SUMMARY OF THE INVENTION In the present invention, the above-mentioned problems can be solved easily by using a slight wind pressure or a slight vibration of a mounting base material for a magnet that is floated by a repulsive force with a plurality of magnets facing the same pole. The solution is to hold it so that it swings.

[0008] For example, magnets floating facing the same pole are swung by wind pressure or vibration by being swingably fitted to a mandrel shaft, or are swingably held in a holding frame. By virtue of the small amount of wind pressure and the slight vibration of the mounting base material, it swings.

[0009]

The plurality of magnets have the property that the same poles repel each other. The present invention utilizes this property to cause a plurality of magnets to face each other with the same poles repelling each other, and to swingably hold these magnets on a mandrel shaft or a holding frame, so that they can be shaken by a slight wind pressure or vibration. It is operated to generate a fluctuating magnetic field.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 is a principle diagram showing a situation in which two disc-shaped magnets 1 and 1 have south poles facing each other and repelling each other. The same is true even if the N poles face each other.

Next, FIGS. 2 to 6 show concrete examples. FIG. 2 and FIG. 3 are a schematic front view and a schematic plan view, respectively, showing the configuration of the axis-floating bird flying prevention device. In the plurality of disc-shaped magnets 1, the same poles face each other, and in a state where they repel each other, the mandrel shaft 2 provided so as to project upward from the base 3 is inserted into the shaft hole 1a. Shaft hole 1a
Has a swingable inner diameter with the magnet 1 held on the mandrel shaft 2. In this embodiment, the lowermost magnet 1
Does not float by using a non-magnetic material for the base 3. In this way, the magnet floating bird flying prevention device is formed as a whole, and is installed on the mounting base material A using the bolt 4. In the magnet floating type bird flying prevention device thus configured, since the plurality of magnets 1 are held in a state of being floated on the mandrel shaft 2, a slight wind pressure caused by flying birds and a slight vibration caused by passing of a vehicle etc. Also rocks.

FIG. 4 and FIG. 5 are a schematic front view and a schematic plan view, respectively, showing the configuration of a bird flying prevention device of a frame floating type. The plurality of disk-shaped magnets 1 are levitated in a frame 5 of a tubular body that surrounds the magnets 1 so that the same poles repel each other so that they do not protrude laterally. In this embodiment, the lowermost magnet 1 is pushed down by the repulsion and therefore does not float. The magnet floating type bird flying prevention device thus configured is installed using the bolt 4 on the mounting base material A. FIG. 6 shows an embodiment in which the frame 5 surrounds the magnet 1 by several arc-shaped plates, and the front view is shown in FIG.
Is the same as In the magnet floating type bird flying preventive device thus configured, since the plurality of magnets 1 are held in a state of being floated in the frame 5, a slight wind pressure due to flying birds and a slight amount due to passage of a vehicle or the like may occur. It also swings due to vibration.

Any one of the magnet floating type bird flying prevention devices shown in these embodiments can be arranged according to the situation of the site.

[0014]

According to the first to third aspects of the present invention, a plurality of magnets are made to face the same pole, and the magnets levitated by the repulsive force are swingably held, so that the magnets are always in a floating state. Therefore, it fluctuates even with a slight wind pressure and a slight vibration to generate a fluctuating magnetic field. Further, the oscillation continues after that, and the fluctuating magnetic field continues to be generated for a long time.

In the second and third aspects, since the magnet levitated by the repulsive force is swingably held by the mandrel shaft or the holding frame, the appearance is simple and there is no sense of discomfort even if installed in any place.
