[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bird coming-in prevention device for preventing birds, for example, pigeons, sparrows, crows, etc., from coming to temples, train stations, balconies of houses, eaves, warehouses, fields, etc.

[0002]

[Prior Art]

 Traditionally, wild birds have been regarded as unfavorable for living in cities, that is, the harmful thing is that the birds that settled in a certain place pollute the place with feces excreted. As a result, the aesthetic appearance is impaired, and the feces can be a source of infection by various pathogens. In particular, since feces are acidic, they discolor car coatings and oxidize metal objects such as reinforcing bars to promote discoloration or corrosion. Furthermore, it is said that the number of birds that have become accustomed to urban life these days is increasing not only by degrading the agricultural products in the fields, but also by using household waste as their food. In addition to the above, damage by bird calls, defeathering, nests, etc. has occurred. Therefore, in order to prevent damage from these birds, so-called pseudo-eyeballs, windmills, artificial sounds, various pseudo-models, etc., in which a large eyeball is drawn on the balloon surface, have been conventionally devised.

[0003]

[Problems to be solved by the device]

 However, conventional equipment and devices can only be installed in places that are limited in terms of aesthetics and cost, and while they are effective for the time being after installation, they have long-term efficacy. Was not. For example, in a pseudo-eyeball, a bird that does not care about this movement will not escape, and onomatopoeia and the like are effective in preventing the arrival of birds, but on the other hand, it creates new environmental pollution as noise and can always be used. is not.

However, in recent years, homing properties in birds are related to the magnetic ore inside the head, and it has been announced at academic societies and is becoming popular. In view of the above points, the present invention disturbs the magnetic ore of birds by causing anomalous magnetic field locally, gives an unpleasant sensation, and prevents homing, and harms other than birds. It is intended to provide a bird flight prevention device that can be easily installed in any place without giving it.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a thread wire provided with locks at both ends, a branch wire having one end fixed at a proper position of the thread wire, and another end fixed to the branch wire, with a magnet body inside. The gist is a bird flight prevention device consisting of a spherical magnetic material that is internally mounted in a floating state, and it is also possible to make birds more uneasy by using transparent threads such as Tegus or nylon as the thread line and branch line. It was Further, by adjusting the length of the thread to be stretched, the thread can be easily stretched according to the distance between the locked members such as columns for stretching the thread. Also, as the branch line, change the length of the other branch line adjacent to it to make it easier to disturb the magnetic field generation, and use sulcan, which is mainly used as a fish tool, as a fixing means for the branch line and the thread line. Thus, it is possible to freely rotate about the branch line and to generate magnetic field disturbance in multiple directions by rotating about the thread line. Furthermore, by drawing a pseudo eyeball on the outer surface of the magnetic material, such as a bird's unfavorable color, the effect is not only on the magnetic ore of the bird, but it also gives a visual fear or discomfort. It is to prevent it.

[0007]

[Action]

 As described above, the bird flying prevention device of the present invention has one end of a branch wire fixed to a suitable position of a thread wire provided with locks at both ends, and a magnet body is attached to the other end of the branch wire in a floating state. A spherical magnetic material is fixed, and it can be easily attached to the vicinity of the bird's landing point by just stretching the thread line with the above-mentioned locking tool. It can be adjusted without being affected by the member spacing. Even if the magnetic body of this device is in a stationary state, it will affect the magnetic ore of birds, but since the magnet body is installed in a floating state, for example, birds may come into contact or wind If a part of the device, such as a magnetic substance, a branch line, or a thread line, oscillates due to, for example, the magnetic field flow in a stationary state is changed, and the magnetic field is disturbed by this change, stimulating the bird's magnetic ore It gives a feeling.

【Example】

 The details of the present invention will be further described with reference to the accompanying drawings. 1 is an explanatory perspective view showing an embodiment of the present invention, FIG. 2 is an explanatory perspective view showing another embodiment of the present invention, and FIG. 3 is an explanatory perspective view showing an embodiment of a magnetic body of the present invention. FIG. 4 is a cross-sectional view of a magnetic body according to the present invention, and FIG. 5 is an explanatory perspective view showing another embodiment of the magnetic body according to the present invention. That is, the reference numeral 1 in the figure is a transparent thread such as Tegus, nylon thread, piano wire, or a thread line made of a thread that is hard to see. Further, locking tools 2 are provided at both ends of the thread line 1, and the locking tools 2 are those which are directly locked to the locked member 3 or the locked member 3 is wound. A thread fastener that can be locked to the thread line 1 is adopted, and further, a thread fastener such as a cotton fastener that can adjust the locking position to adjust the tension length or the tension strength of the thread line. Adopted. However, in a place where the locked member 3 does not exist as in this embodiment, for example, in a field, etc., it is possible to solve the problem by using a supporting tool (not shown) such as a rod as necessary. Then, at an appropriate place of the thread line 1, one end of a thread-like branch line 4 formed of the same material as the thread line 1 is fixed with an adhesive or the like, or a salcan mainly used for fishing equipment, etc. Stick through. When this sulcan is used, it can be rotated around the branch line 4 as a central axis, which can easily disturb the magnetic field of the magnetic substance described later in different directions, but on the other hand, the sulcan itself is visible to birds. Therefore, the reason why the thread line 1 and the branch line 4 are made transparent or difficult to see is to prevent the birds from seeing them and to slightly obstruct the purpose of contacting the thread line 1 or the branch line 4. However, it is an effective means from the viewpoint of magnetic field disturbance, and is appropriately selected depending on the place where the device is installed. Further, the magnetic field range can be changed by changing the length of the branch line 4 and the other branch line 4 adjacent to the branch line 4 as shown in FIG. It is conceivable that the distance between the four branch lines 4 is set to be at least the length of the long branch lines 4 so that adjacent branch lines 4 are not entangled with each other, and preferably about twice the branch lines 4.

Further, as shown in FIGS. 3 and 4, an example of one or a plurality of magnetic bodies 5 fixed to the other end of the branch line 4 is shown. The magnetic body 5 is a spherical body in which a spherical magnet body 6 is internally mounted in a floating state, and a locking piece 7 for fixing the branch line 4 is provided upright on the upper or lower part. However, in this embodiment, a thin resin such as a synthetic resin material formed into a spherical shape is adopted. Further, it is naturally possible to incorporate a plurality of the magnet bodies 6 or to form a synthetic resin material in which a magnet is impregnated into a spherical shape. FIG. 3A shows an example in which a single magnetic body 5 is fixed to the tip of one branch line 4, and when a plurality of magnetic bodies 5 are fixed to one branch line 4. Can be solved by forming the locking pieces 7 on the upper and lower portions of the magnetic body 5, as shown in FIG. 3B, for example. However, although it is certain that the magnetic field generated around the magnetic body becomes stronger as the number of magnetic bodies 5 increases, the magnetic field range of one magnetic body 5 (the magnetic force decreases as the distance from the magnetic body 5 increases), If there is at least one in the range that can be given to birds, it is not necessary to increase blindly, and if the magnetic force is simply increased, using a kid-type magnet body 6 as compared to a simple magnet. It is well known that its magnetic force is strong, and we are currently experimenting with this magnetic field range. FIG. 5 shows another embodiment of the magnetic body 5, in which the magnetic body 5 is disturbed by the magnetic body 5 by drawing a color or pattern which the bird does not like. Not only that, but it also visually prevents flying of birds. For example, as shown in the figure, a pseudo eyeball 8 is drawn on the surface of the magnetic body 5, or in the center which is not shown, the whole is colored red, A typical one is a black circle.

[Effect of the device]

 According to the bird flight prevention apparatus of the present invention configured as described above, attention is paid to the fact that the magnetic ore inside the body of the bird is a major factor that determines the homing property, directionality, etc. In order to prevent the magnetic ore from being disturbed, the magnetic substance is in a floating state without being fixed in position, so that the magnetic field range is changed to disturb the magnetic ore. Also, when the thread or branch is made transparent, it is expected that birds will come into contact with this thread or branch, and the contact will cause the magnetic substance to vibrate violently, resulting in extreme magnetic field disturbance. To ward off birds. However, if the installation location of this device is a place with strong wind, it is natural that magnetic field disturbance will occur regardless of the contact, and at least the movement of this branch line is not constant and monotonous. If it is an irregular one that cannot be predicted, it will be possible to prevent the birds from coming in without getting used to them. In addition, it is possible to visually prevent flying by drawing a color or pattern that the bird does not like, such as pseudo eyeballs, on the surface of the magnetic material. It can be easily installed in most places where you want to prevent it.
