Detailed Description of the Invention

[0001]

The present invention relates to a bird damage prevention device for preventing damage from harmful birds such as starlings, crows and sparrows in the cultivation of various crops such as rice and tomato as well as fruit cultivation of cherries and pears. In particular, it is an object of the present invention to provide a bird chasing tool having a novel structure which makes it difficult for a harmful bird to get used to and has a long-term prevention effect.

After the selection work in early spring, fertilization, and other work, the buds that have just started to sprout can be eaten, and disinfecting work, pollination work, thinning work, and other labor-intensive work are repeated to bring up fruits with great effort. The damage that various crops such as cultivated are messed up near the harvest time is a serious problem for growers because it directly affects the yield, and various measures to prevent it In addition to the various binding cords and hanging cords that have been widely used for a long time as tools, various shapes and structures are lined up in stores every year, and the most suitable one is selected. Cultivating farmers who have to select and adopt have no guarantee that what was effective in the previous year will be effective again in that year, and their effectiveness cannot be confirmed unless they are used. From the fact that knows well on the experience of the door, I get busy to gather information for the.

In the case of a binding cord or a hanging cord made of a vapor-deposited film having a gold-silver-like glossy surface, it is not always clear how effective the bird damage is, but it has been used for a long time in fields and fields. However, branches such as orchards extend intricately, and they are tall and are not often used in places where visibility is not good, so that instead of spreading sesame or nets, it may cause pollution. In addition to installing a powerful explosion sound generator, find the equipment that the bird fears or hates, such as hanging the hanging pattern such as the first pattern, the design of the natural enemy, and recently a powerful magnet etc. Have been commercialized.

[0004] However, in order to spread nets and install a roaring sound generator, a large amount of light cost is required, and a great deal of time is required for complete maintenance. In some cases, it is not possible to achieve complete control, such as the fact that some of the birds do not have the desired effect, such as some birds that are less effective, etc. After that, the fact is that the bird damage prevention measures are expected to have some effect, such as giving up looking around halfway.

In this situation, when looking at the actual situation of a particularly simple hanging type bird damage prevention device, for example, a hanging device with a first pattern or a hanging device using a ferromagnetic material is available. Even if it is uncomfortable for the harmful bird, it is suspended in the same place in a stable state, and when I look at it for a long time, there is absolutely no surprise,
It was not devised to suddenly encounter something strange, so it is highly possible that the timidity of the harmful birds could not be used.

Therefore, for example, Japanese Patent Laid-Open No. 60-15374.
Invention No. 3, Invention No. 60-22185, No. 1
No. 8131, No. 2-46576, No. 5-268862, No. 8-80153, etc. are devised for rotating the display portion with the first pattern. Characterized in that it causes a change in the reflection of light, or, for example, the actual Kaihei 4-1
No. 03483, No. 4-43025, No. 4-43026, etc. have been proposed, all of which are certainly compared to those already in practical use,
Although a new movement is added and it is recognized that there is a possibility that it may cause a sudden action to the harmful birds and raise alertness, the structure of the former structure and the latter type respectively When it is complicated or requires a large-scale structure and a large number of pieces are needed in a wide area such as an orchard, there are many tools that are not always suitable. .

In view of such a situation, the present invention is interested in a hanging type bird-catching device which has a particularly simple structure and is suitable for use in large numbers at low cost.
After many years of experimentation in the field, compared with this type of preventive device that has been put to practical use or proposed so far, it can be realized with a much simpler structure. Although it is a fixed position type, it can be expected that sudden changes can always be expected with changes in the weather, and it has been verified that the harmful rotation of the harmful birds is clearly dampened in the invasion behavior. The expression bird catching tool has been completed, and the configuration thereof will be described in detail below by taking up some concrete examples.

As will be clearly understood from the examples described later, the hanging rotary bird catching device of the present invention has the following structure. That is, it is composed of a strip-shaped corrosion-resistant thin plate having a bow structure having a wind-holding portion which is greatly curved, and has one side of which has a metallic luster finish surface and is covered with a transparent temporary adhesive surface protective thin film layer, On the other hand, one side of is a yellow or gold single color, or it is a painted finish surface with those colors as ground colors so that multiple striped patterns of different colors such as black and red appear. At the center of the upper end, a hanging string with an untwisting metal fitting interposed is attached to the center of the upper end, and at the center of the bow-shaped structure that serves as the wind-holding portion, a block-shaped block for controlling the posture of the corrosion-resistant thin plate is provided. It is a hanging rotary bird catching tool that attaches and integrates metal pieces.

More specifically, it is composed of a strip-shaped corrosive-resistant metal thin plate having a bow structure having a wind-holding portion, which is curved to a large extent, one side of which has a metallic luster finish surface and a transparent temporary adhesion surface. Whether it is covered with a protective thin film layer and the other side is made yellow or gold single color, or multiple stripes consisting of different colors such as black and red appear with those colors as ground color On the other hand, at the center of the upper end, attach a hanging strap with an appropriate length at the center of the upper end with an untwisting metal fitting interposed, and at the center of the bow-shaped structure that becomes the wind holding part. Can be a hanging rotary bird catching device having a configuration in which a massive metal piece for attitude control of a corrosion-resistant thin metal plate is attached in a protruding shape and integrated.

More specifically, it is composed of a strip-shaped corrosion-resistant metal thin plate having a bow structure having a wind-holding portion, which is curved to a large extent, and has a metallic glossy finish on one side and is transparent. Cover with an adhesive surface protection thin film layer and make the other side yellow or gold single color, or make them appear as multiple striped patterns consisting of different colors such as black or red with ground color as the background color. On the other hand, while making it a painted finish surface,
At the center of the upper end, attach a hanging string with an untwisting metal fitting on the tip side, and at the center of the bow-shaped structure that serves as the wind holding part, control the attitude of the corrosion-resistant thin metal plate. It can be said that the gist of the configuration is a hanging rotary bird catching device in which a massive metal piece for use in a projecting manner is attached and integrated so that the mass of the projecting side is large.

The corrosion-resistant thin plate is a portion that forms the base of the bird chasing device of the present invention, and has a strip shape as a whole (a vertically elongated shape is sufficient, and therefore, a rectangular outside shape, a vertically elongated elliptical shape, and their contours are appropriately used. It is possible to use uneven shapes.), And materials that can maintain a bowed structure with a large lateral curvature for a long period of time, such as those made of various synthetic resins by injection molding, aluminum plates, stainless steel plates, etc. It is formed of a curved metal plate that does not easily corrode, and the concave side is used as a wind holding part, and the structure is such that the wind is held in the same place and the force of the wind is easily received. There must be.

Moreover, in this corrosion-resistant thin plate, the surface on the side of the wind-holding portion is formed as a mirror surface, and the light reflected by the movement of itself becomes a slightly converging state like a concave mirror, and is as far as possible. In addition to being reflected, up to the rotation and fluctuation of the corrosion-resistant thin plate itself so that the light reaches irregular directions, so that good reflected light can be obtained, if the material is synthetic resin, Mirror surface is made by plating or metal foil is laminated and integrated into a mirror surface to form a mirror surface by any known means, and if it is made of a thin metal plate, it is polished to make it transparent. A good reflection effect can be obtained by providing a coating layer or by making it difficult to produce gloss, for example, by using a brass plate or a copper plate, by plating or by bonding and integrating a metal foil for forming a mirror surface. Is formed to It must have, as a result,
It is not only emitted from one point with uniform light, but the threatening effect on the harmful birds is enhanced. By the way, in order to prevent the mirror surface of the corner from getting dirty or scratched before the use stage, it is assumed that a transparent temporary adhesive surface protection thin film layer is attached beforehand to the surface, and it is used at the use stage. It should be peeled and removed.

On the other hand, the opposite surface of the corrosion-resistant thin plate, that is, the convex surface side, is not a mirror-finished surface as described above, but is a painted surface such as yellow or gold, or these are ground-colored and black or other dark-colored It is necessary to combine the strips so that the striped pattern becomes the exposed surface, and the corrosion-resistant thin plate rotates,
Light from the mirror surface is intermittently emitted when rocking, while when rotation or rocking is slow or stopped, the ground color or the ground color with a striped pattern warns the harmful birds. Shall function. It should be noted that the finish surface of this surface is preferably such that the ground color portion is not peeled off by applying a paint finish, but if the durability equivalent to that is expected,
It goes without saying that it is of course possible to adopt a structure in which printing sheets and the like are laminated and adhered.

In the posture of the above-mentioned corrosion-resistant thin plate, that is, in the posture in which the upper end is suspended by a suspending cord, which will be described later, the curved metal piece has a curved lower end edge which projects right below the suspending portion and is slightly upward. The function is to suppress and control the tendency of the bow-shaped structure to be moderately adjusted, and is attached to the central portion of the bow-shaped structure that serves as the wind-holding portion, and preferably, the tip is heavy to form a protruding shape. It is attached with the structure so that the rotation from the hanging part around the vertical axis can be caused from the hanging part as much as possible, and even a slight wind force can cause smooth rotation and rocking. It must be formed, and a metal piece having a columnar shape, a prismatic shape, a T-shape, or the like is attached to a predetermined location of the corrosion-resistant thin plate by an appropriate means such as adhesion, screwing, or the like and integrated. In addition, this lump metal piece is formed of a ferrite magnetic body or other magnetic body itself, or has a structure in which a magnetic body is attached only to the tip part, and the property that harmful birds dislike strong magnetic field lines was incorporated, It may be designed to be a more effective bird catching device.

The hanging string serves to attach and hang the above-mentioned anticorrosion thin plate to a branch of a fruit tree, windproof net, windproof net or the like where bird damage is desired to be avoided, such as fishing line. It is possible to use not only a tough string but also a wire with a resin coating, etc., and a structure with a twist-back metal fitting will be placed in the middle of the place so that the lower corrosion-resistant thin plate can rotate smoothly. Should be. Hereinafter, the bird-catcher represented by the present invention, which is shown in the drawings, will be specifically described so that the structure of the hanging rotary bird-catcher included in the present invention can be more clearly understood.

[0018]

Second Embodiment Another typical embodiment of the present invention is shown in the whole perspective view of FIG. 5, the central vertical sectional view of FIG. 6, and the enlarged vertical sectional view of the essential part of FIG. In this embodiment, the base material of the corrosion-resistant thin plate 1 is made of an aluminum thin plate, has a bow-like structure that is largely curved by press molding or manual processing, and the concave surface side that becomes the wind holding portion 15 is polished. The surface 11 has a metallic luster finish, and the convex side is
An eyelet metal fitting is fitted into a small hole formed in the finish surface 11 of a gold background and formed near the center of the upper end to form a hanging hole 14 that protects the cut surface. One end side of the fishing line hanging string 4 The untwisting metal fitting 3 is attached to the other end of the hanging string 4, and the upper end ring of the metal fitting 3 is provided with a mounting portion 41 made of vinyl-coated wire (for example, product name Vinitai) or the like. It has a structure that makes it easier to suspend at the installation location.

[0020]

In the hanging rotary bird chasing device of the present invention having the above-described structure, the transparent temporary adhesive surface protective thin film layer is gently peeled off, and the hanging string is used to branch fruit trees, windproof nets, or It is a horizontal member supported by columns properly, and is used by suspending it at appropriate intervals at locations where there is no risk of the corrosion-resistant thin plate touching, and the wind-holding part of the corrosion-resistant thin plate is used.
Since it is formed so as to reliably receive the wind and be easily influenced by the wind, the bird-catching device of the present invention tries to start rotating even with some wind. At that time, the lumpy metal piece controls the posture of the corrodible thin plate, and as a result, a smooth rotation close to the rotation around the vertical axis passing through the suspended portion is guaranteed, and as described above, it is not. Even if the bird chasing tool according to the present invention is easily influenced by the wind, it is rotated and rocked by the wind to rotate and rock very smoothly.

In the process of rotation and rocking, the concave metallic lustered surface reflects sunlight on the wind-holding portion side of the corrosion-resistant thin plate in a converging manner, and the reflected light is reflected by the rotating shaft. It becomes a reflection in a non-constant direction due to the rocking of, and when viewed from a certain place, it will always be reflected as a light of a sudden phenomenon, and the effect of threatening the harmful bird becomes enormous. Since there is no reflection on the convex coated surface,
The reflection of the reflected light has the effect of promoting the emission in a more complicated state.

Further, in the state of being stopped without being affected by the wind, the repellent effect which has already been proved in the hanging cord or the binding cord provided with the light reflecting base material which reflects the metallic luster from the past is exhibited. , Corrosion-resistant thin plate Expected in the ground color of the convex side or the part of the ground color with a stripe pattern added,
This will have an effect on the harmful birds that fly up to nearby, and will have the effect of preventing damage to the fruit to the minimum. Both of these effects are due to the inconsistent wind strength. In addition, it will always be brought in a complicated relationship, and the effect of avoiding harmful birds will be further enhanced.

In particular, the hanging rotary bird catching device shown in the first embodiment has a characteristic that the structure is extremely simple and suitable for mass production, and it can be provided as a cheaper bird catching device. In the case of the structure of Example 2, the mass of the tip portion depends on the material of the corrosion-resistant thin plate 1, and in the embodiment, the size of the magnetic body 2 or the size of the magnetic body attachment piece 21 or the length of the protruding rod portion 22 thereof. By changing the thickness, etc., the advantage that the posture control can be optimized can be obtained, and the corrosion-resistant thin plate can be appropriately deformed like a metal material, and its curvature can be appropriately changed. If so, it is possible to change to a bow structure that realizes the smoothest rotation and swing in accordance with the average wind strength at that place, and it can be used as a bird catcher with higher practical value. Will be guaranteed The ones that feature also is exhibited say.

As described above, the hanging rotary bird catching device of the present invention is, due to its characteristic structure, difficult to handle and manage due to its complexity, and the phenomenon caused by it is scarcely changed. Compared to those that were insufficient in terms of the harmful bird intimidating effect or the harmful bird avoiding effect, etc., it is easy to manufacture and can be provided at low cost, handling and management are extremely easy, and the power of wind without power is used. Fruits and other products that have been carefully created for growers of fruit trees, etc., who are in a situation similar to wisdom compared to harmful birds, because they have been able to effectively use and effectively realize a complicated repellent environment for a long time. It is expected that it will be widely adopted and popularized as it will greatly contribute to the protection of birds from bird damage and the economic effect.
