Description

  The present invention relates to a bird control device that prevents birds such as pigeons and crows from entering a veranda or a bay window.

  In recent years, birds such as pigeons and crows inhabiting cities have increased, and feces excreted by these birds and fecal pollution caused by pathogenic bacteria contained therein have become a problem. For example, on the verandas and bay windows of apartments, birds such as pigeons and crows often stop instead of perching and rest, and the verandas and bay windows are often soiled by feces. . Therefore, in order to prevent birds such as pigeons and crows from entering a veranda or the like, various bird eviction devices and devices are provided.

As a conventional bird control device of this type, for example, the applicant of the present patent application previously applied for a utility model registration and is described in Patent Document 1. Patent Document 1 describes a bird repelling device for preventing birds such as pigeons and starlings from entering a veranda.
The bird repelling device described in Patent Document 1 includes a support column and an arm having a central portion fixed and attached to the upper portion of the support column. A magnetic body is provided at both ends of the arm, and the arm has a central portion. It is configured to be swingable as a fulcrum.

Japanese Utility Model Publication No. 7-30077 (page 2-3, FIGS. 1-11)

  However, in the above-described conventional bird repelling device, a magnetic object attached to both ends of the arm is used to repel birds that do not like magnetism, and when a magnetically insensitive bird tries to stop on the arm, the arm is shaken by its own weight. I was moved to surprise the birds and fly away. Therefore, this bird repellent device cannot effectively perform its function unless the bird approaches the arm or contacts the arm.

  The present invention has been made in view of such a conventional problem, and even if a bird does not approach or come into contact with a bird control device, an arm or a support column is caused by the action of a naturally flowing wind. Oscillates so that the magnets can rotate naturally and allow the magnetism to swing around. An object of the bird control device that swings by the wind is to allow birds such as pigeons to be seen from a distance so that the birds do not enter a veranda or a bay window.

  In order to solve the above-described problems and achieve the object of the present invention, the bird control device of the present invention has a support column and an axial middle portion extending in a direction substantially orthogonal to the direction in which the support column extends. And a pair of magnets attached to both sides in the axial direction of the swing arm. At least one of the support column and the swing arm can be bent and deformed, and at least one of the pair of magnets, the swing arm, and the support column is subjected to wind to bend at least one of the support column and the swing arm. It is characterized by the provision of blades that increase the oscillation due to deformation.

  Moreover, although the bird control apparatus of this invention is not necessarily limited, it is preferable to provide a blade | wing on a pair of magnet. Similarly, although not limited, the pair of magnets is composed of a combination of two magnet pieces that can be joined to each other, and the blades are composed of a sheet-like or plate-like member having a diameter larger than that of the magnet pieces, The blade may be sandwiched between two magnet pieces and fixed with an adhesive, or may be riveted or swaged. The pair of magnets may be rotatably supported by the swing arm, and the pair of magnets may be provided with a plurality of wind-receiving pieces that protrude outward in the radial direction. Furthermore, the blades can be fixed to the swing arm. And a blade | wing can be set as the structure which rotatably supports to a rocking | swiveling arm or a support | pillar, and attaches a magnet to the blade | wing. Moreover, it is preferable that the magnetic force of a magnet exists in the range from 1000 gauss to 1500 gauss.

  According to the bird control apparatus of the present invention, even when the bird does not approach or come into contact with the bird control apparatus, at least one of the swing arm and the support column is swung by the action of the naturally flowing wind to swing the bird control apparatus. The bird can be surprised by the swing of the moving arm and the magnet, and the magnet can be swung around by bending the swing arm or the support column. As a result, the birds can be afraid by swinging the swinging arm and the like, and the birds can be driven away by the magnetic field generated by the magnet attached to the swinging arm. Intrusion can be prevented.

  Further, according to the bird control device of the present invention, by providing the pair of magnets with the blades, the magnet can be efficiently swung so that the wind directly hits the magnet. At this time, a pair of magnets is formed by a combination of two magnet pieces, and a blade is formed of a sheet-like or plate-like member having a diameter larger than that of the magnet piece, and the blade is made of two magnets. A magnet having blades can be easily and inexpensively manufactured by sandwiching it with a piece and fixing it with an adhesive, a rivet or the like. In addition, a pair of magnets are rotatably supported on the swing arm, and each magnet is provided with a plurality of wind-receiving pieces projecting radially outward, so that the magnets are rotated and the magnetism of the magnets is surrounded by the rotational force. Can be scattered.

  Furthermore, according to the bird control device of the present invention, by providing the blades integrally with the swing arm, the magnet can be swung by applying wind force to the swing arm. In addition, the blade is rotatably supported on at least one of the swing arm and the support column, and the magnet is attached to the blade, thereby rotating the magnet through the blade and scattering the magnetism of the magnet around by the rotational force. Can do. In addition, by setting the magnetic force of the magnet within a range from 1000 gauss to 1500 gauss, pigeons and crows can be generated without causing harmful effects such as radio wave interference by the magnet on the veranda or bay window where the bird control device is installed. It is possible to effectively prevent the birds such as pigeons and crows from approaching the veranda or the like by generating a magnetic field of a magnet that is reluctant to birds.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1, the bird control device 1 according to the first embodiment of the present invention includes a support column 2, a swing arm 3, two tip magnets 4, 4, and one central magnet 5. And the stand 6.

  The support column 2 is formed by a coil spring (spring support) having an appropriate elasticity. The spring column 2 has a first end 2a and a second end 2b that protrude outward in the axial direction at both ends in the axial direction. As the material of the spring support 2, for example, stainless steel, spring steel and other metal spring materials are suitable, but engineering plastics having appropriate strength and elasticity can also be used. The spring column 2 is disposed with its axial direction directed in the vertical direction, and a second end 2b disposed below is fixed to and supported by the stand 6. In addition, the spring support | pillar 2 can also be formed with the pillar material which does not have elasticity or is elastic and has a very small rigidity.

  A spherically formed central magnet 5 is attached to the tip of the first end 2 a disposed above the support 2. The central magnet 5 is provided with a through hole penetrating in a direction perpendicular to the central magnet 5, and the tip of the first end 2 a is penetrated through the vertical through hole. The swing arm 3 is passed through the horizontal through hole of the central magnet 5. The vertical through hole and the horizontal through hole may be formed to intersect each other directly so as to intersect each other, or may be configured to intersect so as not to intersect with a predetermined gap. When orthogonally crossing the two through holes, the first end 2a of the support column 2 and the swing arm 3 are integrally formed orthogonal to each other. When the two through holes do not intersect with each other, the first end 2a of the support column 2 and the swing arm 3 are formed separately and independently.

  The height position of the central magnet 5, that is, the height of the support column 2 varies depending on the type of birds to be controlled. For example, when targeting a pigeon, about 10 cm, when targeting a crow Is preferably set to about 20 cm. The reason is that the height of the head of a pigeon is generally about 10 cm and the height of the head of a crow is about 20 cm. Further, the length of the swing arm 3 varies depending on the number, size, weight, and the like of the magnets. For example, as shown in the illustrated embodiment, when the magnets are arranged at the central portion and the three ends, The total length is preferably about 30 cm to 50 cm.

  The swing arm 3 is formed of a wire having an appropriate strength (for example, a piano wire, a spring steel wire, or the like). An intermediate portion in the axial direction of the swing arm 3 is fixed to the central magnet 5 so that the swing arm 3 can move integrally with the central magnet 5. Left and right tip magnets 4 and 4 are rotatably attached to both ends of the swing arm 3 in the axial direction. Each tip magnet 4 is supported rotatably with respect to the swing arm 3 while preventing movement in the axial direction by crimping the front and rear of the swing arm 3 in the axial direction. The left and right tip magnets 4 and 4 may be configured to be fixed to the swing arm 3 by adhering means such as an adhesive or press-fitting.

  As shown in FIG. 2, the tip magnet 4 is formed by two hemispherical magnet segment pieces 4a and 4b, and as a whole, the tip magnet 4 composed of one sphere is constructed. ing. Each magnet division piece 4a, 4b is provided with a through hole 7 penetrating the central portion thereof. One end of the through-hole 7 is opened at the center of the flat portion of the magnet split pieces 4a and 4b, and the other end is opened at the center of the curved surface portion. A blade 8 having a diameter larger than that of the magnet segment pieces 4a and 4b is sandwiched between the two magnet segment pieces 4a and 4b so as to be integrally formed.

  The blade | wing 8 is formed of the disk-shaped member which has a larger diameter than the diameter of the magnet division pieces 4a and 4b. As the material of the blade 8, for example, metal, plastic, paper, rubber, or other plate material can be used. A central hole 9 penetrating between the front and back surfaces is provided in the central portion of the blade 8. The blade 8 is for receiving wind flowing around the tip magnet 4 and is not limited to the circular shape shown in this embodiment as long as it can receive the wind. Other examples of the shape of the blade 8 include, for example, a quadrangle, a hexagon, an octagon, a star, and other various shapes. The two magnet segment pieces 4a and 4b and the blades 8 may be fixed using an adhesive, or may be sandwiched by the magnetic force of the two magnet segment pieces 4a and 4b.

  The tip magnets 4 and 4 and the center magnet 5 can be applied in various sizes and shapes as long as the strength of the generated magnetic force is in the range of 1000 gauss to 1500 gauss. In general, birds such as pigeons and crows are known to dislike the magnetic force of magnets, and when magnetic force is applied to the brains of pigeons and crows, pigeons and crows can be dissipated from the place. For this purpose, the strength of the magnetic force of the magnet is preferably in the range of 1000 gauss to 1500 gauss, and the preferred strength is about 1300 gauss. The reason is that when the magnetic force is less than 1000 gauss, since the strength of the magnetic force is weak, there is little influence of the magnetic force on pigeons and crows, and it is difficult to dissipate pigeons. Further, when the magnetic force is 1500 gauss or more, the influence of the magnetic force on the surrounding environment becomes too large, which may cause harmful effects such as radio wave interference. On the other hand, when the magnetic force is about 1300 gauss, it is possible to reliably control pigeons and crows by making the magnetic force act reliably on pigeons and crows approaching the magnetic field.

  The stand 6 is for supporting the support column 2 with good stability, and has a support plate 11 formed in a disk shape. A support shaft 12 for supporting the second end 2 b of the support column 2 is provided at the center of one surface of the support plate 11.

The support plate 41 of the stand 6 is provided with a plurality of insertion holes 42 for screwing the stand 6 to a handrail of a veranda.

  FIG. 10 is a diagram illustrating an example of a usage pattern of the bird control device according to the embodiment of the present invention. The bird control device 1 (15, 18, 28, 33, 38) according to the present invention described above is a place where it is difficult for the birds to stop and dung, for example, the handrail 51 of the veranda 50 of a residential apartment, the apartment It can be installed on the roof of temples, temples, panapets on the roofs of buildings, and decks of small ships.

  The bird control device 1 (15, 18, 28, 33, 38) is fixedly or detachably attached to a desired position such as a handrail 51 of the veranda 50 or a roof. When the bird control device 1 (15, 18, 28, 33, 38) is fixed and attached at a desired position, for example, the stand 6 is fixed using an adhering means such as an adhesive or welding. On the other hand, when the bird control device 1 (15, 18, 28, 33, 38) is detachably attached to a desired position, for example, a detachable attachment means such as a fixing screw or a magnet is used.

  Here, when a fixing screw is used as the fixing means, for example, as illustrated in FIG. 10, an insertion hole 42 is provided in the support plate 41 of the stand 6, and the insertion hole 42 and the fixing screw are used for fixing. That is, the screw shaft portion of the fixing screw is inserted into the insertion hole 42 of the support plate 41, the tip of the screw shaft portion is screwed into the screw hole provided in the handrail 51, and the handrail 51 or the like is fixed with the fixing screw. The bird control device 1 (15, 18, 28, 33, 38) is tightened and fixed at the position.

  Moreover, when using a magnet as a fixing means, a magnet is fixed to the lower surface of the support plate 11, for example. In this case, when the mounting surface of the stand 6 is a magnetic metal material, the bird control device 1 (15, 18, 28, 33, 38) can be placed at a predetermined position such as the handrail 51 only with a magnet attached to the support plate. ) Can be detachably attached. On the other hand, when the attachment surface of the stand 6 is a nonmagnetic surface such as wood or concrete that does not have magnetism, a magnet or a magnetic plate is attached to the nonmagnetic surface. This makes it possible to easily remove the futon when it is not necessary, for example, when drying the futon on the veranda.

  It is preferable to install a plurality of bird control devices 1 (15, 18, 28, 33, 38) in a straight line. In this case, between the adjacent bird control devices 1 (15, 18, 28, 33, 38), the same magnetic poles are made to face each other (pluses or minuses), so that the magnets repel each other and swing more greatly. It becomes possible.

  Here, when pigeons, crows, and the like approach the handrail 51 to stop on the handrails 51 of the veranda 50, the surroundings of the bird control device 1 (15, 18, 28, 33, 38) by the flapping of pigeons, crows, etc. The air is disturbed, and the wind generated by flapping is blown to the bird control device 1 (hereinafter, reference numerals 15, 18, 28, 33, and 38 are omitted). Since the wind pressure at this time is substantially proportional to the area receiving the wind pressure, the wind force acting on the left and right tip magnets 4 and 4 and the central magnet 5 is larger than the wind force acting on the support column 2 and the swing arm 3. In particular, since the blades 8 are respectively attached to the left and right tip magnets 4 and 4, the wind force acting on the left and right tip magnets 4 and 4 is larger than the wind force applied to other portions. And since the support | pillar 2 which supports the rocking | fluctuating arm 3 is formed by the coil spring which has big elasticity (flexibility), the center magnet 5 and the rocking | fluctuation arm 3 have the lower part of the support | pillar 2 as a rocking | swiveling center, The left and right tip magnets 4, 4 are swung in a certain direction.

  Accordingly, the left and right tip magnets 4 and 4 are largely swung in the same direction according to the rotation amount of the swing arm 3. By the large movement of the left and right tip magnets 4 and 4, pigeons and crows can be surprised to fly away. Furthermore, the magnets are scattered around by the swinging of the left and right tip magnets 4, 4, and the magnetic field around the bird control device 1 is fluctuated to be an abnormal magnetic field so that the birds can be kept away.

  Thus, according to the bird control device 1 (15, 18, 28, 33, 38) of this embodiment, birds such as pigeons and crows dislike magnetism, so that they are kept away from the veranda 50 and the roof. Can be driven away. Even if a bird that is insensitive to magnetism tries to stop on the swing arm 3, the swing arm 3 swings loosely, so that the bird can be surprised to fly away.

  In the above-described embodiment, the example in which the swing arm 3 and the magnet are installed in one stage on one plane has been described. However, the swing arm 3 and the magnet are installed in a plurality of stages on two or more planes. Can do.

  As described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, an example in which a coil spring is used as the support 2 has been described. Therefore, the support can be elastically deformed and the swing arm can be swung (or turned) greatly. It may be formed of a rigid body such as a hollow pipe. In this case, only the swing arm can be elastically deformed to swing (or rotate) the left and right tip magnets.
