BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing birds such as pigeons from entering a veranda or the like.

[0002]

2. Description of the Related Art In recent years, birds such as pigeons, crows, sparrows, and starlings that inhabit cities have increased, and excreted feces and pathogens have become a problem. For example, a method using a false eye, a needle, an ultrasonic wave, or the like has been proposed in order to prevent the above problem. Among them, bird repellent devices that use magnets, focusing on dislikes strong magnetism that disturbs the biomagnetism of birds themselves (which judge the direction of flight and are signs of homing) Have been proposed, and for example, an apparatus disclosed in Japanese Utility Model Publication No. 4-10789 is known.

[0003]

However, a method of simply attaching a plurality of hemispherical magnets at predetermined intervals to a tension line as in the invention disclosed in this publication has a certain degree of effect, but has a certain effect. However, there is a problem that satisfactory results cannot be obtained for the user, for example, the pigeon is insensitive to the above, and stops at the tension wire between the hemispherical magnets. The present invention has been made in view of the above-described conventional problems, and has as its object to provide a bird repellent device that can efficiently and reliably prevent birds such as pigeons from stopping on a veranda or the like.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a plurality of cylindrical magnets suspended in a horizontal direction between pillars so as to rotate when birds stop. and a cylindrical body with loosely fitted to the wire so as to cover the wire as a whole, the magnet is obtained by placing the cylindrical body between the magnets to be positioned at appropriate intervals. The present invention may also be configured such that a magnet is mounted on an impeller rotatable by wind, and the impeller is mounted on the support.

[0005]

According to the present invention, since the cylinder is loosely fitted between the magnets so that the magnets are located at appropriate intervals, it is possible to prevent a bird who dislikes magnetism from approaching, and is insensitive to magnetism. Even if the bird tries to stop, it cannot stop because the magnet and the tube rotate with respect to the wire, and escapes with a surprise. For this reason, birds, such as a pigeon, can be efficiently prevented from entering a veranda or the like. When an impeller with a magnet is mounted on a support, the impeller rotates due to the wind, causing a change in the magnetic field, and the area around the impeller is changed to an abnormal magnetic field to keep birds away. In addition, birds are surprised at the rotating impeller and become less accessible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an embodiment of a bird repellent device according to the present invention, and FIG. 2 is a partially enlarged sectional view thereof.

[0007] In these figures, 1 is a column such as a bolt, a round member, a square member, a plate, etc., 2 is a wire such as a wire suspended between the columns 1, and 3 is a rotatable wire 2 so as to cover the wire 2. The cylindrical magnet 4 fitted into the wire 4 is a cylindrical magnet positioning washer 5, and the cylindrical body 5 is rotatably fitted in the wire 2 like the magnet 3 so that the plurality of cylindrical magnets 3 are positioned at appropriate intervals. It is.

[0008] The pillar 1 is a place where birds do not have to stop and dung, for example, a handrail 6 on the veranda of a residential condominium, an adhesive 7 on a roof of a condominium or a temple, a building roof, or the like.
Fix with bolts. The height of the support 1 is changed depending on the type of bird. For example, it is preferably about 10 cm for a pigeon and about 20 cm for a crow. Since the cylindrical magnet 3 and the cylindrical body 5 are rotatably fitted into the wire 2, even if a bird tries to stop at this magnet, it cannot rotate and stop. The magnetic force is such that the bird feels the magnetism and affects the biomagnetism of the head. According to experiments, the magnetic force is 1500 gauss or more, and the distance between the magnets 3 is about two.
About 0 to 30 cm is preferable. The cylinder 5 is made of a relatively lightweight material such as straw, plastic or the like so that it can be easily rotated.

As a method of mounting the bird repellent device,
First, dust, oil, bird droppings, and the like on the surface of the installation place (for example, the veranda handrail 6) are thoroughly cleaned, and then fixed to the support base 8 with an adhesive 7 or screws. Then, after removing the nut 9 at the upper end of the support 1 and alternately fitting the cylindrical magnets 3 and the cylinders 5 of a predetermined number into the wire 2, the coil is wound once around the bolt head 1 a, and then tightened with the nut 9 to fix the peak. The remaining wire 2 is wound or cut around the shortest bolt. When the bird repellent device of this embodiment is installed in this way, the bird does not approach the magnet 3 because the bird dislikes magnetism. Also, even if a bird insensitive to magnetism tries to stop on the magnet 3 or on the cylindrical portion 5 between the magnets 3 and 3, the magnet 3 and the cylindrical body 5 are rotatable about the wire 2 as an axis. Because of that, it turns and surprises and flies away. For this reason, it is not polluted with feces.

FIGS. 3A and 3B show another embodiment of a bird repellent apparatus, in which a rotatable impeller 10 is mounted on the support 1 and a magnetic ball 12 is fitted into the impeller 11. FIG. . The blade 11 of the impeller 10 is rotated by the natural wind or the wind generated by the flapping of the bird's blade, and the magnetic field flies around, so that the same magnetic force can affect a wide range. In the experiment, depending on the wind power, 10
It was confirmed that the influence was up to about 100 times (approximately 2.0 to 30 m when installed at the intervals of 20 to 30 cm). This impeller 10 has the advantage that the number of magnets 3 can be reduced in some cases, and the use of natural winds does not require any driving costs. In some cases, the magnet 3 and the cylindrical body 5 are pressed against each other to prevent the wire 2 from being exposed.
-It may be urged by an urging member such as a coil spring from both sides of 1 toward the center.

FIG. 4 shows the bird repellent device of the present invention with a tiled roof 13.
The repelling device in which one wire rod 2 is stretched over the entire width of the roof is further shown in FIG.
This is an example in which the entire roof is attached in parallel at 0 cm intervals. With this installation, the entire roof has magnetism, no birds approach at all, and there is no danger of being polluted by feces.

FIGS. 5 and 6 show an example of a simple bird repellent device in which the cylindrical magnet 3 and the cylindrical body 5 are previously fitted into a plate-shaped support 14 and an impeller 10 is set at the center. Adhesive or one of the known attaching / detaching tools 15a is attached,
If the other attachment / detachment tool 15b is fixed in advance to the installation location of the apparatus, for example, a veranda handrail, it can be easily attached / detached, and has an advantage that it can be easily removed when unnecessary such as when drying a futon on the veranda. In addition, there is an advantage that no trouble is required for the installation because it is assembled in advance.
