DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird proofing device and a bird proofing device capable of preventing bird harm in a building such as fecal pollution caused by birds such as pigeons flying on the building.

[0002]

2. Description of the Related Art In general, birds, especially pigeons, have a habit of stopping at a beam of a building or an opening for a window, and a building is a good place for a pigeon to rest and stop. When the pigeon stops, pigeon droppings are left on the structure, but the pigeon droppings damage the appearance of the structure, oxidize and corrode the structure, contaminate it, and spread the pathogens to the human body. The substance has an adverse effect and produces an odor. In addition, flying pigeons generate noise. For this reason, bird harm such as fecal pollution has become a social problem in recent years, and there is a strong need for excellent bird proofing equipment and bird proofing equipment.

[0003] As a conventional bird-proof facility, there has been proposed a bird-proof facility that uses a net to prevent a pigeon from flying, stopping, or entering. In this method, a net is formed over the entire surface of a building, such as an opening for a window or a bird-proof part of a building. By setting such a net, a pigeon cannot stop or enter the building.

[0004]

However, as described above, bird-proofing equipment using a net has a net over the entire area of the bird-proofing spot in the building, which greatly impairs the appearance of the building, and The cost required for installation and maintenance work of the vehicle increases. In addition, it is conceivable to perform a partial bird protection treatment on a building other than the bird protection equipment, but it is difficult to perform reliable bird protection.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to provide reliable bird protection without impairing the aesthetics of a building, and to install and maintain the bird at low cost. It is an object to provide a device and its birdproofing equipment.

[0006]

According to the present invention, there is provided a bird-proofing device having a telescopic elastic part having a locking means at a tip thereof, and a through hole provided at a center thereof so that the elastic part can be adjusted to expand and contract. A fitting portion fitted to the elastic portion, inserted into the through hole,
And a striated portion having a retaining means at the inserted end. For example, a hook or the like as the locking means, a spring or rubber as the elastic part, a bolt or the like as the fitting part, a stopper or the like as the retaining means, and a wire such as a stainless wire as the linear part. Use etc.

Further, the birdproofing equipment of the present invention is provided with a stretchable elastic portion having a locking means at the tip and a through-hole at the center, and fitted to the elastic portion in a state where the expansion and contraction of the elastic portion can be adjusted. Using a bird-proofing instrument having a mating fitting portion and a linear portion inserted into the through hole and having a retaining means at the inserted tip, at a position less than approximately 2 cm from the edge of the installation location The bird protection device is characterized in that the wire section is stretched so that the tension can be adjusted at predetermined intervals of less than about 4 cm.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a bird protection apparatus and a bird protection equipment according to the present invention. FIG. 1 is a side view showing the bird-proofing device of the present invention in a stretched state, and FIG. 2 is a partially longitudinal side view showing the bird-proofing device of the present invention.

In FIG. 1 and FIG. 2, a bird-proofing device 1 mainly comprises a spring 2 which is formed with a hook-like hook 2a at its tip and which can be extended and contracted in a longitudinal direction, and a shaft portion on which a bolt head 3a and a male screw 3c are cut. 3b through hole 3 in the center of the hexagon bolt
d comprises a bolt 3 penetrating in the longitudinal direction, and a linear portion 4 having a stopper metal 4a made of aluminum or the like at at least one end.

[0010] The spring 2 has a bolt 3
Male screw 3c is screwed and can be removed. When the filament portion 4 is stretched, when the bolt 3 is tightened to increase the screwing amount of the male screw 3c, the spring 2 is extended and the filament portion 4 can be tensioned, and the bolt 3 is loosened to screw the male screw 3c. When the combined amount is reduced, the spring 2 contracts and the striated portion 4 can be relaxed, and the tension of the striated portion 4 can be adjusted. Further, the striated portion 4 is inserted into the through hole 3 d so that the stopper metal 4 a provided at the tip is not caught by the tip of the bolt 3. As the bolt 3, for example, a hexagonal bolt (4 mm × 25 mm) made of stainless steel is used.
The diameter of d is 2 mm or the like. In addition, the filament part 4 has, for example, a diameter of 0.5 to 1.0 m in which seven fine stainless steel wires are twisted.
m is used and its surface is coated with nylon.

Next, a case will be described in which the above-mentioned bird-proofing equipment is disposed at a required place such as a building to provide bird-proofing equipment. FIG.
FIG. 2 is a front view showing the birdproofing equipment of the present invention.

In FIGS. 1 and 3, the bird-proofing equipment using the bird-proofing equipment 1 is provided in an opening 10 in a window frame portion of a building, and includes a spring 2 and a bolt screwed thereto. Numerals 3 are arranged on the bottom surface 10a of the opening 10 at predetermined intervals, and the striated portions 4 are stretched from the upper surface 10b of the opening 10 to the bottom surface 10a.

In the above birdproofing equipment, the angles 12 are fixed to the bottom surface 10a and the upper surface 10b by anchor bolts 11, respectively. The angle 12 is, for example, 3 mm × anodized.
20mm x 30mm angle, vertical standing part 1
An engaging hole 12b for the striated portion 4 or the hook 2a is provided in 2a. Engagement hole 12b of standing portion 12a on bottom surface 10a
The hook 2a of the spring 2 is locked to the end, the end of the striated body 4 is passed through the locking hole 12b of the erected portion 12a of the upper surface 10b, and the end of the striated body 4 is an aluminum lock. It is fixed to the striated portion 4 by a fixing portion 5.

Since the distal end of the linear portion 4 is stopped by the distal end of the penetrating bolt 3, the tension of the stretched linear portion 4 is determined by the amount of screwing of the bolt 2 to the spring 2. Adjustment is possible by utilizing the expansion and contraction of the spring 3.

The upright portion 12a of the angle 12
The spring 2 is provided at a position within approximately 2 cm from the edge of the bottom surface 10 a or the top surface 10 b, and is located at a position of approximately less than 2 cm.
And a bolt 3 are arranged, and the linear portion 4 is stretched in a vertical direction. Further, the bird protection device 1 is provided at predetermined intervals of less than approximately 4 cm in the longitudinal direction of the angle 12, and the linear portions 4 are stretched. This is because taking into account the minimum distance 4 cm at which the pigeon can directly enter from the flying state, and setting the depth space to less than 2 cm, there is no room to stop from the flying state. If there is an interval of 4 cm or more, the pigeon can directly enter from the flying state,
In addition, if there is a space of 2 cm or more, the space once stops and closes the blade, and then enters through a space of 4 cm in width. Pigeons have the ability to learn, and once they have tried and determined that invasion is impossible, they give up entering the area.

In the above-mentioned bird-proofing device 1 and bird-proofing equipment, the case where the spring 2 and the bolt 3 are provided at one end of the wire portion 4 has been described, but they may be provided at both ends of the wire portion 4 with the same configuration. The configuration in which the striated portion 4 is stretched to attach the bird-proofing device 1 to a building is also appropriate in other than the above-described embodiment, and it is possible to install the bird-proofing device 1 in various buildings, structures, and the like by using various mounting devices. , Its applicability is extremely high. In addition, since an intermediate base material is not required when attaching the bird-proofing instrument 1, installation cost and the like can be suppressed.

Further, since the striated portion 4 is extremely thin, the striated portion 4 is not conspicuous, does not impair the aesthetic appearance, and does not obstruct the field of view and external light. Furthermore, the wire section 4 is made of twisted stainless steel wire and covered with nylon, etc., so that the bird-proofing equipment and bird-proofing equipment are all-weather type, have excellent weather resistance, and have durability against corrosion and ultraviolet rays. Can be excellent.

The bird-proofing device 1 comprises a spring 2 and a bolt 3
Can be adjusted to adjust the amount of threading, and the filament 4 can be tensioned or relaxed, and the spring 2 and the bolt 3 can be detached to remove the tensioned filament 4. In the work or building maintenance or repair work, the linear part 4
Work can be easily performed without cutting or removing itself. In addition, since the bird-proofing device is easily detachable, it can be used for purposes other than bird-proofing.
