Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wild bird flight control device.

[0002]

2. Description of the Related Art Due to environmental changes, recently,
Various birds such as pigeons often nest in houses and various structures, and along with this, pollution caused by excrement of wild birds is becoming serious. In particular, in buildings such as stations and factories, so-called H-shaped steel is often used as a frame structure material, as shown in FIG. 19A, and beams made of H-shaped steel are left exposed on the attic or the like. The horizontal surface of this H-shaped steel is a good nesting place for pigeons. Specifically, in the case of the top beam in the middle of the building, Fig. 19 (b)
As shown in (1), a gap of about 10 to 20 cm is created between the lower surface of the second floor and the roofing material for structural reasons, and wild birds such as pigeons fly in here, making it a good place to stay. When pigeons make nests in such places, a large amount of pigeon droppings and the like fall under the nests and adhere to people and products that pass underneath, causing damage to clothes and products. .

In order to prevent such damage, the following various types of wild bird flying control devices for pigeons have been developed. (1) Bird-following balloons As shown in Fig. 20, a balloon in the shape of "eyes" that makes the bird feel a sense of fear is installed at a place where wild birds are likely to fly.
It is a way to keep wild birds away from such places. It is common to see such balloons installed in farm orchards. However, if this bird-following balloon is attached to a building, it will spoil the appearance. It is effective at the time of installation, but soon it gets used to it and the effect disappears. It is impossible to keep the same state for a long period of time, and there is a problem such as danger if gas leaks and hangs down and there is a high voltage line.

(2) Canned odor Canned odor is a canned product containing a substance that produces an odor that birds and the like do not like. By installing this canned product in a place where birds can fly and nest, It is designed to prevent flying or nesting (see FIG. 21). This canned food is effective at the time of installation, but it is not 100% perfect, and pigeons soon become accustomed to this smell and come flying. Furthermore, this odor generation has a limited life and must be replaced. In addition, canned food is dangerous to drop, close to people, and cannot be used in places with infants. Further, if the place where the canned food is installed is high, the work becomes difficult. In addition to the above, the odor control of birds is not limited to the above-mentioned canned foods, but any problem has the above-mentioned problems.

(3) Magnet It is known that the pigeon has a homing instinct that utilizes the earth's magnetism, so that it is possible to distort the sense of direction of the pigeon when a high magnetic field is generated by the magnet. Is a method of controlling pigeons with a magnet. As shown in FIG. 22, a large number of magnets are installed on a handrail, a beam or the like using wires or the like to prevent the dove from stopping on the beam or the like. The flying control method using a magnet is said to be the most effective and effective control method at present. However, this magnetic control method is not very effective for other wild birds. About 40% of pigeons are used to living in a high magnetic field and stop forcibly. Furthermore, since the dove touches the body of the pigeon, the attachment part eventually peels off, and the line comes off and breaks, causing a aesthetic problem. Also, in a building with a steel frame, the magnets will eventually become pillars,
It sticks to the beam and loses its effect, and on top of that a large magnet is at risk of falling. There are problems such as the installation work is very difficult.

(4) Wires or Wires As shown in FIG. 23, a method in which a large number of wires are stretched around a place where a pigeon or the like is likely to fly to eliminate the space for the pigeon or the like to stop. According to this method, one obstacle iron wire is not effective in a place where the width of the surface is large, and even if two or three wires are attached in parallel, the wire stays between the wires. The wire will loosen if the bracket is not attached properly. Construction is difficult to fix the bracket securely. In particular, welding is required for steel aggregates, which may cause a fire hazard and damage the product. Further, this method has a problem that the effect can be exhibited only by about 30% as a whole.

(5) Net As shown in FIG. 24, the net is stretched around a place where a pigeon or the like is likely to fly, so that the pigeon or the like is not stopped by a beam or the like. According to this method, the appearance of the building is impaired by the net, and it is very difficult to attach a net attachment member, a metal object, and the like. Since the net mounting hardware is bolted or welded, there is a risk of damaging the product below or the product. It is impossible to completely block the space between the net and the building by actual work. As a result, the net offers a great place for pigeon nesting. Further, it is impossible to close up the space of the details, which is a very rough work, and the pigeons continue to fly in most places where measures have been taken.

(6) Attachment of Iron Plate, etc. This is a method of welding and fixing an iron plate, etc. on a beam where a pigeon or the like is likely to come in and stop. This method, by welding the cut iron plate,
It is dangerous because it is attached to a beam. Installation costs are very high. As it becomes more visible, additional work such as painting work will increase. There is a problem such as.

(7) Combination of each of the above-mentioned flying control devices It has been attempted to prevent wild birds such as pigeons from flying by properly combining the above flying control devices. Has the drawbacks mentioned above,
It is not always effective in preventing the flight of pigeons.

[0010]

Therefore, from the background described above, the present inventors have found that they are easy to install, can be easily installed anywhere, and even if a pigeon or the like comes in, they will stay on a beam or the like. We propose a flying prevention device that can be completely prevented,
It is intended to solve the above problems. This wild bird flight control device is designed to slope the horizontal planes such as beams at the high places inside the building preferred by pigeons and to close the gaps in the building to prevent nesting. , It can be easily applied to various shapes of places, and it does not hurt people's eyesight or aesthetics.

[0011]

[Means for Solving the Problems] The technical means taken by the present invention to achieve the above-mentioned technical object comprises a fixed surface and a sliding surface which are connected at an angle of a predetermined angle or more. It is fixed to a horizontal surface such as a beam at a high place inside a building that pigeons prefer, and the horizontal surface such as a beam is sloped by the sliding surface, and the gap between the buildings is closed to prevent nesting of wild birds. It is in the fly control equipment.

[0012]

[Function] The fixed surface of the flying bird control device is placed on the horizontal surface of the beam. At this time, mount so that there is no gap between the upper end of the sliding surface and the vertical wall. Further, if there is a protrusion or the like on the vertical surface, a necessary notch may be formed on the free end side of the sliding surface so as to avoid it. The slit portion on the sliding surface side is turned over, and in this state, the fixing surface and the horizontal surface of the beam are fixed by an appropriate fixing means such as a U clip or a bolt clip, and then the rolled surface on the sliding surface side is bent to cover the clip head. , Installation is complete. In this way, by mounting a plurality of flying prevention devices on all horizontal surfaces of the beam where a pigeon or the like is likely to stop, it is possible to reliably prevent flying birds. According to this method, even when the beam is looked up from below, the flying prevention device does not come into contact with the eyes and does not impair aesthetics.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a wild bird flight control device according to a first embodiment of the present invention, and FIG. 2 is a perspective view of a wild bird flight control device according to a first embodiment of the present invention with a fixing surface facing upward,
FIG. 3 is a cross-sectional view of the wild bird flying prevention device according to the first embodiment of the present invention, and FIG. 4 is a mounting explanatory view of the wild bird flying prevention device according to the first embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes a flying bird control device, and this flying control device 10 comprises a sliding surface 1 and a fixed surface 2. The sliding surface 2 is a surface for preventing the bird from stopping, and the fixed surface 2 is a surface for mounting the flying prevention device on a beam or the like. The fixed surface 1 and the sliding surface 2 are formed, for example, by bending a single tin plate or stainless steel plate whose surface is hard to stop even if a bird tries to stop, and the width WA of the surfaces 1 and 2 is WB can be freely determined according to the width of the beam to be mounted, but normally the following dimensions are basically manufactured in advance in a factory.

[0015]

[Table 1]

As shown in FIG. 4, the flying pest control device in which the width WA of the sliding surface 1 is constant forms the angle θ between the sliding surface and the fixed surface, as shown in FIG.
It is possible to cope with beams of various widths simply by changing. The fixed surface 2 is a surface for fixing the pest control equipment to a beam or the like, and can have a necessary width WB, but it is considered that the optimum width is usually 50 mm. Further, the length L of the flying prevention device may be appropriately set according to the attachment site.

On the sliding surface 1 side, a plurality of U-shaped slits 3 are formed at intervals of 60 to 70 cm as shown in the drawing along the bending line between the sliding surface 1 and the fixed surface 2. A plurality of pairs of slits 4 having a predetermined length are formed on the free end side of the fixed surface. These slits may have any suitable size, but it is preferable that the slit 3 is about 4 cm square, and the slit 4 is about 2 cm wide and about 3 cm long in consideration of the size and workability of the clamp for fixing the flying prevention device.

The angle θ between the sliding surface 1 and the fixed surface 2 is optimally about 40 degrees as shown in FIG. This angle θ is the minimum angle at which the bird cannot slide and stop even if it tries to stop. However, this angle can be changed as shown in FIG. 4 depending on the state of the portion to be attached, and as a result, even if the flying rod-shaped device has the sliding surface 1 formed to have a constant width, the width WH of the horizontal plane varies. Can be adapted to beams. Since the flying pest control device having the above-mentioned configuration is developed only for use on the upper surface of the horizontal surface of the beam where wild birds may stop, and because it is formed as a slope having a sliding surface angle of 40 degrees, It is barely noticeable and is aesthetically pleasing.

Next, the procedure for attaching the wild bird flying prevention device will be described with reference to the drawings. (1) When attaching a flying pest control device to a beam made of H-shaped steel (Figs. 5 to 8) To attach the flying pest control device 10 of a wild bird to a beam made of H-shaped steel, first, as shown in FIG. The surface defined by the U-shaped slit 3 is turned upward, and the angle θ (40 degrees or more) is changed according to the width of the beam, and the fixed surface 2 is placed on the horizontal surface of the beam (FIG. 6). At this time, mount so that there is no gap between the upper end of the sliding surface and the vertical wall.
Further, if there is a protrusion or the like on the vertical surface, a necessary notch may be formed on the free end side of the sliding surface so as to avoid it.

In this state, as shown in FIG. 7, the fixing surface 2 and the horizontal surface of the beam are fixed by an appropriate fixing means such as a U clip 5 or a bolt clip 6, and then the above-mentioned rolled surface is bent to cover the clip head. Installation is complete. In this way, by mounting a plurality of flying prevention devices on all horizontal surfaces of the beam where a pigeon or the like is likely to stop, it is possible to reliably prevent wild birds from flying (FIG. 8). According to this method, even when the beam is looked up from below, the flying prevention device does not come into contact with the eyes and does not impair aesthetics.

(2) When attaching a flying prevention device to the furring strip made of C-shaped steel (FIGS. 9 to 11), as shown in FIG. 9 (a), the surface of the sliding surface 1 defined by the slit 3 is directed upward. Turning up and changing the angle θ (however, 40 degrees or more) according to the width of the furring strip, the fixing surface 2 is placed on the horizontal surface of the furring strip as shown in FIG. At this time, mount so that there is no gap between the upper end of the sliding surface and the vertical wall. In this state, as shown in FIG. 9 (b) and FIG. 10 (b), insert a finger from the opening of the sliding surface and bend the slit surface of the fixing surface 2 downward (c of FIG. 10) to fix it to the opening of the furring strip. To do. After that, the above-mentioned rolled surface is bent to close the opening and the attachment is completed (FIG. 11). In this way, by mounting a plurality of flying prevention devices on all horizontal surfaces of the furring strip where a pigeon or the like is likely to stop, it is possible to reliably prevent flying of wild birds.

Next, a wild bird flying control device according to a second embodiment of the present invention will be described. This embodiment is for preventing wild birds from stopping between the beam and the floor or roof on the second floor as shown in FIG. As shown in FIG. 13, the flying prevention device is W-shaped, and a fixed surface 2 is formed at the lower end of each sliding surface 1. As shown in FIG. 13, this flying prevention device can be mounted by changing the shape of the mountain shape or the folding depth of the mountain shape according to the gap H and the width W of the mounting place. On the side of the sliding surface 1, the sliding surface 1
A plurality of U-shaped slits (not shown) are formed at intervals of 60 to 70 cm along the bending line between the fixed surface 2 and the fixed surface 2, and the free end of the fixed surface is formed. A plurality of pairs of slits (not shown) having a predetermined length are formed on the side.

This double mountain type flying prevention device is attached to an H-shaped steel in the same manner as in the first embodiment, but has a sliding surface of 40.
Since it has an angle of -60 degrees, it does not come in contact with the eyes, and since the clip used is commercially available, the appearance is not deteriorated. There is no problem even if there are existing fluorescent lights, smoke detectors, and other wiring. Easy to install and semi-permanent. Easy to remove and install even when wiring work etc. Since the width can be changed freely, it can be used in any field.
