Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. 1, (a) is a front view showing the first net 12 in the first bird repelling net 10 according to the present invention, (b) is a perspective view showing the first locking member 14, and (c) is 2 is an exploded perspective view showing a magnet 16. FIG. 2A is a front view showing a state in which the first bird repelling net 10 is attached, and FIG. 2B is a partially enlarged view thereof. FIG. 3 is an explanatory diagram showing a usage state of the first bird repelling net 10. 4A and 4B are explanatory views showing a state in which the first bird repelling net 10 is attached to a building.

The first bird repelling net 10 is composed of a first net 12, a first locking member 14, and a magnet 16, and can be easily installed in a building such as a veranda in an apartment to repel birds such as pigeons. It can be done.

The first net 12 is knitted from a plurality of elastic horizontal cords 17 and a plurality of vertical cords 18 crossing the horizontal cords. For example, polyethylene, which is a strong special resin material used for high-voltage electric wires and the like. It consists of wire rods mainly made of stainless steel.

For the knitting of the first net 12, for example , a string having a thickness of about 0.8 mm is used, a plurality of strings are arranged in parallel at intervals of about 25 mm, and then a horizontal string 17 is formed, and then a plurality of pieces at the same intervals These strings are arranged in parallel, and both are crossed at about 90 degrees to form a vertical string 18. And what is necessary is just to fasten the other string sequentially in the intersection 19 with respect to one string. In addition, it is not always necessary that the wire diameter of the horizontal string 17 and the vertical string 18 is the same.

Therefore, the mesh 20 of the first net 12 is about 25 mm square , for example, which is a size that can be easily pulled out by itself even if a pigeon or the like accidentally puts a neck. In addition, as described above, the thickness of the string is about 0.8 mm, which is a wire diameter that becomes inconspicuous when installed in a building together with the coating by photocatalytic processing described later, It means that the wire diameter is also strong enough not to be cut by a pigeon or the like.

Each string is previously coated with a coating (not shown) by photocatalytic processing using , for example, titanium dioxide. This photocatalytic processing is generally said to have a self-cleaning action of decomposing various bacteria, toxins and harmful substances into clean water and carbon dioxide gas, and not only can the first net 12 be kept clean (disappearance). Odor, sterilization, antibacterial action), and dirt that adheres to the surface of the net is prevented, and the first net 12 does not stand out even when used for many years.

The first locking member 14 is entirely formed of a metal material such as stainless steel, for example, and has a fixing portion 22 that is a smooth flat plate at the bottom. For example, when the fixing portion 22 is attached to a flat wall surface using a strong adhesive , the fixing portion 22 has such a size that the first locking member 14 can have a load resistance of 1 kg.

The first locking member 14 has a slightly narrowed tip, and is bent in a curl shape , for example, to form a connecting portion 24. The first net 12 can be pulled by being locked, such as by inserting some stitches 20 into the connecting portion 24, or by hooking the ends of some strings formed in a ring shape.

The tip shape of the first locking member 14 is not limited to the illustrated curl shape, but may be anything that can pull the tip of the string or the mesh. For example, like the third locking member 52 used in the second bird repelling net 30 to be described later, the tip is slightly narrowed, bent at about 120 degrees to form a hook portion, and further a connection hole is formed in the center of the hook portion You may employ | adopt the shape which was made. In this case, even if it is a general person, it is easy to connect a string, and the installation operation | work of the 1st net | network 12 becomes very easy, without relying on a specialist.

The magnet 16 is made of, for example, a plastic magnet and can be attached to the first net 12 with sufficient durability. The magnet 16 is composed of hemispheres 26 and 27 having N and S poles. Make a sphere. This magnetic sphere has a strength of about 1300 gauss.

In addition, on the inner side surface (cut surface) of each hemisphere 26.27, a cross-shaped groove portion 28 is formed in which a horizontal string and a vertical string can be inserted, and a substantially square is formed in the center, and an intersection of both nets is inserted. can do. Therefore, the magnets 16 can be attached to the first net 12 by combining the hemispheres to sandwich the first net 12.

In order to use such a first bird repelling net 10, firstly, a strong adhesive is used on the veranda of the apartment where the first locking member 14 is to be installed, and the horizontal direction is about 25 cm as a guide. Install vertically. At this time, if the wall painting of the apartment, such as belanda, is scraped with a screwdriver or a cutter, etc., and the bonded first locking member 14 is temporarily fixed with gummed tape for about one day and then removed the next day, etc. The one locking member 14 can be reliably fixed to the wall surface. In addition, in order to maintain sufficient strength, the first locking member 14 is attached to both the horizontal and vertical wall surfaces in the vicinity of each corner.

Secondly, the first net 12 is cut into a predetermined size, the ends in the four directions on both the upper and lower sides are folded back inward, and the hook of the first locking member 14 is hooked on the mesh 20 of the folded portion. At this time, in order to prevent the first net 12 from slackening, the hook after being hooked on the mesh 20 may be further rounded with pliers or attached with an adhesive and crushed with a hammer or the like.

Third, the first magnet 16 is attached to the mesh 20 of 12 cm from the wall surface at one corner. At this time, the hemispheres 26 and 27 of the N pole and the S pole are combined, and the intersection (cross portion) of the first net 12 is sandwiched by the groove 28, and the inner surfaces of both hemispheres are further fixed with an adhesive. Next, based on the first magnet 16, for example, the magnet 16 is fixed to the entire first net 12 at intervals of about 25 cm.

When this first bird repelling net 10 is installed on the veranda etc. of an apartment, even if a pigeon flies, it affects the biomagnetism inherent to birds within the range of magnetism and feels magnetism and is shocked. Surprise, flip and fly away. If a pigeon or the like comes into contact with the first net 12, the first net 12 swings and the attached magnet 16 swings back and forth and left and right. It is said to be a range.) Is expanded, and the pigeons can be further surprised.

Moreover, the first bird repelling net 10 coated with photocatalyst processing does not get dirty even after long-term use , and the thickness of the string is about 0.8 mm , Even if it is installed in Veranda, it is almost invisible from a distance.

In the second net 32, for example, a thick auxiliary string 33 having a wire diameter of about 2 mm to 5 mm, preferably 3 mm, is further attached in the vicinity of the ends in the four directions on both the upper and lower sides. The auxiliary string 33 is attached by cutting a knitted basic net into a predetermined size, turning up ends in both the upper and lower sides inward, and alternately inserting the auxiliary string 33 into the mesh 40 of the folded part. The material of the auxiliary string 33 is the same as that of the horizontal string.

The second locking member 34 includes a connecting portion 44 whose tip is bent in a curl shape and a flat circular plate fixing portion 42, which are the same as the first locking member 14, and thus description thereof is omitted here.

In addition, for example, a coil spring 46 is attached to the distal end of the connecting portion 44 in the second locking member 34 as an expandable member. Therefore, the auxiliary string 33 attached to the second locking member 34 can swing greatly.

Further, in the second bird repelling net 30, a third locking member 52 in which the tip is slightly narrowed , is bent at about 120 degrees to form a hook portion 54, and a coupling hole 56 is formed in the center of the hook portion 54. May be adopted. In this case, even a general person can easily connect the strings, and the installation work of the second net 32 becomes extremely easy.

The magnet 16 is composed of a hemisphere of N and S poles that attract each other, and a cross-shaped and circular groove is formed on the inner side (cut surface) of each hemisphere so as to sandwich the second net 32. Since it is the same as the magnet 16 in the first bird repelling net 10, its description is omitted here.

In order to use such a second bird repelling net 30, first, four corners on both the upper and lower sides on the wall surface of the veranda of the apartment where the second locking member 34 or the third locking member 52 is to be installed. Attach to the part using strong adhesive. Further, a strong adhesive or the like is used for the remaining wall surface with a distance of about 25 cm from the first locking member 14 (of course, it may be the second locking member 34 or the third locking member 52). And attach. The method of attaching these locking members to the wall surface with further strength is the same as that of the first bird repelling net 10.

Secondly, a basic net knitted with horizontal and vertical strings is cut to a predetermined size, the ends in both the upper and lower sides are folded inward, and the auxiliary string 33 is alternately inserted into the mesh 40 of the folded part. To do.

Third, the auxiliary string 33 is attached to the distal end of the second locking member 34 or the third locking member 52 with sufficient tension. Further, the second net 32 other than the four-direction corners hooks some meshes in the same manner as the first bird repelling net 10.

Fourth, the magnet 16 is attached in the same manner as the first bird repelling net 10.

When the second bird repelling net 30 is installed on a veranda or the like of an apartment, the pigeons are surprised as if they were shocked by the magnetism, and flip and fly away in the same way as the first bird repelling net 10 . Further, when a pigeon or the like comes into contact with the second net 32 even a little, the elastic second net 32 swings largely back and forth and left and right, so that the attached magnet 16 also swings greatly, and the range covered by the magnetism ( In general, it is said to be in the range of 16 to 25 cm from the magnet).

In addition, the second bird repelling net 30 does not get dirty even after long-term use, and even if it is installed in a condominium veranda, etc., it will be almost invisible from a distance. As with the first bird repelling net 10, the mesh has a size that can be sufficiently removed.

While some of the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within an equivalent range.
