Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for preventing birds such as pigeons and murk birds from flying into private houses and other structures.

[0002]

[Prior art]

 In order to prevent the pigeons from flying, it is known that a large number of magnets are attached to a wire at predetermined intervals, and both ends of the wire are attached to a support metal (see Japanese Utility Model Publication No. 4-10789).

In such a bird flying prevention device using a magnet, one problem is how to attach the magnet to the filament. However, in the device disclosed in the above-mentioned publication, , A lid mounting hole is provided on the flat surface of the hemispherical magnet, and a mounting projection is provided on the back surface of the lid, and a guide groove is provided to vertically divide the projection into two parts to reach the back surface of the lid. The magnet is attached to the filament by passing it through the guide groove and inserting the protrusion of the lid into the above-mentioned attachment hole of the magnet.

[0004]

[Problems to be solved by the device]

 However, according to the mounting structure as described above, a lid for mounting is required, a mounting hole needs to be provided in the magnet, and a guide groove needs to be provided in the lid. Further, since the lid needs to be fixed to the magnet, there is a problem that the structure is complicated and the manufacturing cost is high.

Therefore, an object of the present invention is to provide a bird flying prevention device in which a magnet is attached to a filament by a simple structure.

[0006]

[Means for Solving the Problems]

 A first means for achieving the above object is a bird flying prevention device in which magnets are attached to a wire at predetermined intervals, and a through hole is provided in the magnet, and the wire is provided in the through hole. A pair of caulking fittings each having a pipe that communicates with the center hole on one side of the flange, insert the flanges of the pair of caulking fittings into the wire on both sides of each magnet with the flanges facing the magnets. The pipe is caulked against both end faces to be integrated with the filament, and the magnet is attached so that the through hole thereof coincides with the direction of the filament.

The second means is a bird flying prevention device in which magnets are attached to the wire at predetermined intervals, and a through hole is provided in the magnet, and a small hole that is aligned with the through hole on one side of the magnet. Apply a holding plate with a hole, insert the wire from the other side of the magnet into the through hole and the small hole of the holding plate by bundling them in two, and tie the insertion end with the outside wire of the holding plate. A knot is formed to prevent the magnet from coming off, and the magnet is attached so that the through hole faces in a direction perpendicular to the direction in which the filament extends.

[0008]

[Action]

 In the bird flying prevention device according to the first and second means, both ends of the filament are attached to columns fixed at a required interval and stretched horizontally. A large number of magnets attached to the filament form magnetic fields of the required strength around them, so birds such as pigeons do not approach the magnetic fields and do not approach them.

【Example】

 1 and 2 show an embodiment of a bird flying prevention device according to the above-mentioned first means, which is a large number of magnets 1, two caulking metal fittings 2 for each magnet 1 and nylon tex etc. And the line 3 of.

The magnet 1 is a ferrite magnet, has a cylindrical shape, and has a through hole 4 formed between the centers of both end surfaces thereof.

The caulking metal fitting 2 is formed by drawing a circular plate, and has a pipe 7 communicating with the central hole 6 on one side of the flange 5.

The wire 3 is inserted into the pipe 7 of each caulking metal fitting 2 and the through hole 4 of the magnet 1, and the pipes 7 are caulked while the flanges 5 of each caulking metal fitting 2 are applied to both end surfaces of the magnet 1. It is integrated with the filament 3.

In this way, the required number of magnets 1 are aligned with the direction of the through holes 4 and the direction in which the filaments 3 extend, and the magnets 1 are attached to the filaments 3 at the required intervals.

A pillar 8 as shown in FIGS. 3 and 4 is used to fix these filaments 3. The column 8 is formed by bending an aluminum material into an L shape and attaching a tightening band 10 to the substrate 9. A fixing screw hole 11 is also provided in the substrate 9. Further, a mounting hole 13 for the wire 3 is provided at the upper end of the standing plate 12.

In order to mount the wire 3 in the mounting hole 13, the caulking metal fitting 2 ′ similar to that described above is used, and the end of the wire 3 is inserted in the direction from the pipe 7 to the flange 5 ′. A knot 14 is formed on the outside of the flange 5'to prevent it from coming off, and the pipe 7'is caulked to be integrated with the filament 3.

The pipe 7 is inserted from the outside of the mounting hole 13, and the flange 5 ′ is brought into contact with the outer surface of the upright plate 12. The substrate 9 is fixed to the handrail of the building's veranda or the like by using the tightening band 10 or the screw hole 11.

When the filament 3 becomes long, the two columns 8 may be back-to-back and the coupling hole 13 ′ may be coupled and fixed with a screw and a nut, as shown by the alternate long and short dash line in FIG. 4.

It is to be noted that hook metal fittings 16 as shown in FIG. 5 may be attached to both ends of the linear member 3 so as to be engaged with the attachment hole 13 of the column 8 or a part of the building. By using this hook fitting 16, it can be easily attached and detached.

Next, FIG. 6 shows an embodiment of a bird flying prevention device according to the above-mentioned second means. In this case, the same magnet 1 as in the above case is used and the through hole 4 Apply the above-mentioned caulking metal fitting 2 on both sides, bend the wire 3 into two and pass it through each pipe 7, and make a knot 15 at the two-folded part of the wire 3 drawn out to one caulking metal 2 side, and prevent it from coming off. Plan. In this case, the magnet 1 is attached so that the through hole 4 is oriented at right angles to the direction in which the filament 3 extends.

In this case, the caulking metal fitting 2 may be only the one on which the knot 15 is formed, and the caulking metal fitting 2 on the opposite side may not be provided. Further, since the caulking metal fitting 2 on the side of the knot 15 is intended to prevent the knot 15 of the filament 3 from coming off, the pipe 7 is not necessarily required, but only the flange 5, that is, a simple holding plate having a small hole. May be

When installing the embodiment of the above-mentioned second means, the pillar 8 similar to that shown in FIGS. 3 and 4 and the hook metal fitting 16 shown in FIG. 5 are used.

FIG. 7 shows the magnet 1 integrated with the filament 3 by passing the filament 3 through the through hole 4 of the magnet 1 and filling the through hole 4 with an adhesive 17.

In any of the embodiments described above, a magnetic field is formed by each magnet 1 in the vicinity where the magnet is installed, so birds such as pigeons avoid the magnetic field and do not approach.

[0024]

[Effect of device]

 As described above, according to the present invention, since the magnet can be attached to the filament by an extremely simple means, the manufacturing cost of the device can be reduced.
