Description
本考案は、大気中に露出した回転可能なカザグルマの羽根の表面に太陽光線を反射するアルミ箔や野鳥の天敵であるハヤブサ、タカ、ワシ等、猛禽類の写真を1個もしくは複数個取り付け、太陽光の可視光線や紫外線等を選択的に受けて乱反射させ、田畑、果樹園、ごみ集積所等に飛来し、カラス、ヒヨドリ、ムクドリ、スズメ、オナガ等の鳥類がその可視光線や紫外線の反射光を受けることによりそれら鳥類の天敵であるハヤブサ、タカ、ワシ等の猛禽類の存在を認識させ、且つ警戒させることにより当該場所に近寄らず、農作物や果実等の被害を免れるために、カザグルマ装置全体の中に2個の回転軸系を持ち、カザグルマの羽根が回転するだけでなくカザグルマの回転する軸と直角方向にも回転可能な軸系を持つ、設置が簡単で簡易構造の鳥飛来防止カザグルマに関する。 The present invention attaches one or more photographs of bird of prey, such as aluminum foil reflecting sun rays on the surface of rotatable feathers of Kazaguruma exposed in the atmosphere, falcons, hawks, eagles that are natural enemies of wild birds, Selectively receives visible rays and ultraviolet rays of sunlight, and diffuses them, then jumps to fields, orchards, garbage dumps, etc., and birds such as crows, buddies, starlings, sparrows, and long-tailed birds reflect their visible rays and ultraviolet rays. Kazaguruma equipment is used to recognize the presence of birds of prey such as falcons, hawks, and eagle by receiving light, and to avoid being damaged by crops and fruits, etc. Easy to install and have a simple structure with two rotating shafts in the whole and not only rotating the blades of kazaguruma but also rotating in the direction perpendicular to the axis of rotation of kazaguruma About birds flying prevention windmill.
従来、日本古来から親しまれてきた折り紙等のジャンルに属するカザグルマは、自然の風の力を受けて回転するため、回転体そのものに色彩性や創作的な形状等の創意工夫が施されて人々に楽しまれてきた歴史がある。一方、カラス等の鳥類の被害を防止するため、ステンレス鋼材を用いて不規則に動くようにして長期間使用しても鳥類が慣れ難く、光を乱反射する効果が少なくなり難い構成にした鳥害防止装置がある。（例えば、特許文献１、実用新案文献２、実用新案文献３参照。）
Traditionally, Kazaguruma, which belongs to the genre such as origami that has been popular since ancient times in Japan, rotates under the force of natural wind, so the rotator itself has been devised such as color and creative shapes. Has a history of being enjoyed by. On the other hand, in order to prevent damage to birds such as crows, bird damage that is difficult for birds to get used to even if used for a long period of time by using stainless steel to move irregularly, making it difficult to reduce the effect of irregular reflection of light There is a prevention device. (For example, see Patent Document 1,
カザグルマが回転する動力源は自然の風に求められ、回転体そのものに色彩性や創作的な形状等の創意工夫が施されて人々に楽しまれるために利用されてきた。時には、田畑等に設置し鳥類飛来を防止する目的で使用されることはあったが、ヒヨドリやカラス等は学習能力が高く、すぐに慣れてそのような効果は無くなるという問題があったものの、カザグルマが風によって動いている時は近寄らないということは確認されていた。
一方、リンゴ園や柿園等では収穫期が近づくとヒヨドリ等の野鳥は果実の成熟度を果実からの太陽光線による反射される紫外線によりそのことを感知し、集団で来襲してそれらの果実をむしばみ、穴をあけ商品価値を損ねるという被害は毎年すべての果樹園にて発生している。
この被害を防止するために、リンゴ園や柿園等の周囲にメッシュの細かい網を設置し、上方には針金等を張って試みているが効果はない。完全に被害を防止するためには果樹園周囲の他に上方部も網で覆うことが必要になるが、広大な面積を覆うためには莫大な費用がかかることになり、これを実行することはないのが実情である。
また、カザグルマ等の回転体の装飾物において、その羽根の表面に太陽光線を反射させるアルミ箔等や野鳥の天敵であるハヤブサ、タカ、ワシ等、猛禽類の写真を複数枚接着あるいは圧着し、太陽光等を選択的に受けて乱反射させ特に羽根車の回転体の凸凹面部に接着、圧着し、低回転あるいは高回転においても太陽光線を不規則に乱反射させると同時にハヤブサ、タカ、ワシ等、猛禽類の写真を接着し、赤、緑、青等の可視光線だけでなく紫外線領域を大変よく反射させて、可視光線のほかに紫外線の色を識別することができるカラス、ヒヨドリ、ムクドリ、スズメ、オナガ等の鳥類に対しハヤブサ、タカ、ワシ等、猛禽類の存在を認識させ、風速、太陽光線の方向、位置によって常に反射光の方向、強さ等が一定ではなく、刻々変わる状況を作り出すことによりヒヨドリ、カラス等の学習能力を混乱させたり、恐怖感を与えることによりカラス、ヒヨドリ、ムクドリ、スズメ、オナガ等の鳥類の飛来を防止し農作物の被害を免れることを目的としたカザグルマは回転したりすることでより効果を発揮することが実験結果において確認されている。一方、カザグルマに正対した方向で、且つ一定以上の風速の風が吹いて初めてカザグルマが回転をするため、そのような風が吹く時はカラス、ヒヨドリ、ムクドリ、スズメ、オナガ等の鳥類の飛来を防止することに効果があったが、風のない時、風速が低い時、風速が早くてもカザグルマに正対する風が吹かない時や微風の時はカザグルマは回転せず、その効果が減退するという問題を有していた。
The power source that rotates Kazaguruma is required by the natural wind, and the rotating body itself has been used to be enjoyed by people with creative ideas such as color and creative shape. Sometimes it was installed in fields and used for the purpose of preventing birds from flying, but chicks, crows, etc. had high learning ability, but there was a problem that such an effect disappeared immediately. It was confirmed that Kazaguruma would not approach when it was moving by the wind.
On the other hand, when the harvest season approaches in apple orchards, wild birds such as budbirds sense the maturity of fruits by the ultraviolet rays reflected by the sun rays from the fruits, and invade them as a group. The damage of punching, punching and detracting from commercial value occurs every year in all orchards.
In order to prevent this damage, attempts have been made by installing a fine mesh net around apple orchards and vineyards, and extending a wire or the like above, but this is not effective. In order to completely prevent damage, it is necessary to cover the upper part of the orchard and the upper part with a net, but enormous costs will be required to cover a vast area. There is no actual situation.
Also, in rotating ornaments such as Kazaguruma, glue or crimp multiple photos of bird of prey, such as aluminum foil that reflects sunlight on the surface of its feathers and wild falcons such as falcons, hawks, eagles, Selectively receive sunlight, etc., and diffusely reflect, in particular, adhere and crimp to the uneven surface of the rotating body of the impeller, irregularly reflect sunlight rays even at low or high rotation, and at the same time falcon, hawk, eagle, etc. Grow birds, birds, starlings, and sparrows that can be attached to a photo of birds of prey, and can reflect not only visible light such as red, green, and blue, but also the UV region, and distinguish the color of UV light in addition to visible light. , Such as falcons, hawks, eagles, and other birds of prey, and the direction and intensity of the reflected light are not always constant depending on the wind speed, the direction and position of the sun rays. Kazaguruma is intended to confuse the learning ability of chicks, crows, etc. by creating frightens, and to avoid the damage of crops by preventing the arrival of birds such as crows, bullies, starlings, sparrows, etc. It has been confirmed in the experimental results that a more effective effect can be obtained by rotating. On the other hand, because the kazaguruma rotates in the direction facing the kazaguruma and blows at a wind speed above a certain level, birds such as crows, dolphins, starlings, sparrows, and long-tailed birds fly when such a wind blows. However, when there is no wind, when the wind speed is low, even when the wind speed is high, the wind does not blow against the Kazaguruma, or when the wind is light, the Kazaguruma does not rotate and its effect diminishes Had the problem of doing.
そこで本考案は、カザグルマ等の回転体の装飾物において、その羽根の表面に太陽光線を反射させるアルミ箔等や野鳥の天敵であるハヤブサ、タカ、ワシ等、猛禽類の写真を1枚もしくは複数枚接着あるいは圧着し、太陽光等を選択的に受けて乱反射させ特に羽根車の回転体の凸凹面部に接着、圧着し、低回転あるいは高回転においても太陽光線を不規則に乱反射させると同時にハヤブサ、タカ、ワシ等、猛禽類の写真を接着し、赤、緑、青等の可視光線だけでなく紫外線領域を大変よく反射させて、可視光線のほかに紫外線の色を識別することができるカラス、ヒヨドリ、ムクドリ、スズメ、オナガ等の鳥類に対しハヤブサ、タカ、ワシ等、猛禽類の存在を認識させ、風速、太陽光線の方向、位置によって常に反射光の方向、強さ等が一定ではなく、刻々変わる状況を作り出すことによりヒヨドリ、カラス等の学習能力を混乱させたり、恐怖感を与えるために、風の方向にかかわらず、また風の風速が低くともカザグルマが回転もしくは揺動可能にして、カラス、ヒヨドリ、ムクドリ、スズメ、オナガ等の鳥類の飛来を防止し農作物の被害を免れることを目的とする。 Therefore, the present invention provides one or more photographs of birds of prey such as aluminum foil that reflects sunlight rays on the surface of its feathers, falcons, hawks, eagle, etc. Adhering or crimping sheets, selectively receiving sunlight, etc., and irregularly reflecting them, in particular, adhering and crimping to the uneven surface of the rotating body of the impeller, and irregularly reflecting sunlight rays even at low or high rotations, and at the same time falcons A crow that can distinguish the color of UV light in addition to visible light by adhering photographs of raptors such as hawks, eagle, etc. and reflecting not only visible light such as red, green, and blue but also the UV region. , Birds, such as fowls, starlings, sparrows, and long-tailed birds, recognize the presence of birds of prey such as falcons, hawks, eagle, etc., and the direction and intensity of reflected light are always constant depending on the wind speed, the direction and position of sunlight. In order to confuse learning skills such as dolphins and crows by creating an ever-changing situation, and to give a sense of fear, Kazaguruma can rotate or oscillate regardless of the direction of the wind and even if the wind speed is low The purpose is to avoid the damage of crops by preventing the arrival of birds such as crows, chicks, starlings, sparrows and long-tailed birds.
上記目的を達するために、本考案は、カザグルマの羽根自身が回転するだけでなく、カザグルマが装着されている回転円筒を貫通するカザグルマ固定軸をも回転することを可能にしたことである。即ち、90度曲げられたカザグルマ固定軸において、カザグルマ本体は従来と同じく設置地面と平行な軸に回転可能な構造とし、90度曲げられたカザグルマ固定軸は設置地面と鉛直な軸に回転可能な構造にしたことである。回転可能な軸系を2系統にしたことにより、カザグルマ装置全体は風が吹くと風の方向に関係なくカザグルマの羽根に風力として作用し、その鉛直軸に回転トルクを与えることになる。設置地面に対して鉛直方向に回転して風の方向とカザグルマそのもの自体が正対するように自動的に動き、風の力を最大限利用できるようになり、カザグルマ装置摺動部の摩擦力が小さいことと相まって、風速が低く微風状態であってもカザグルマは微回転もしくは揺動するようになる。
カザグルマの羽根そのものは任意数の羽根を有し、その表面に任意数のハヤブサ、タカ、ワシ等、猛禽類の写真のみかあるいは円形もしくは矩形のアルミ箔を同時に接着した簡素な構成である。ハヤブサ、タカ、ワシ等、猛禽類の写真の大きさはカザグルマの羽根を覆うぐらいの大きさでも良いし、少なくとも５ｃｍ２以上あればよい。接着する写真の枚数は１枚かあるいはカザグルマの羽根の枚数分が有れば良い。また、本カザグルマは創造的な、カラス等の鳥類が恐怖感を持つ形状にし、また、羽根の色彩は赤、青、黄、緑、黒、白等を単独で、あるいは組み合わせて、田畑、果樹園等に複数個設置することで効果は倍増することは言うまでもない。
In order to achieve the above object, the present invention makes it possible not only to rotate the blade of the kazaguruma itself but also to rotate the kazaguruma fixed shaft that penetrates the rotating cylinder on which the kazaguruma is mounted. That is, in the Kazaguruma fixed shaft bent 90 degrees, the Kazaguruma body is structured to be rotatable about an axis parallel to the installation ground, and the Kazaguruma fixed shaft bent 90 degrees is rotatable to an axis perpendicular to the installation ground. It is a structure. By making the rotatable shaft system into two systems, the entire Kazaguruma device acts as wind force on the blades of Kazaguruma regardless of the direction of the wind, and gives rotational torque to the vertical axis. It rotates in a vertical direction with respect to the installation ground and automatically moves so that the direction of the wind and the kazaguruma itself are directly facing each other, so that the wind force can be used to the maximum and the friction force of the sliding portion of the kazaguruma device is small Coupled with this, even if the wind speed is low and the wind is in a breeze, the kazaguruma will rotate or swing slightly.
The feather of Kazaguruma itself has an arbitrary number of feathers, and has a simple structure in which only an arbitrary number of falcons such as falcons, hawks, eagle, etc., or a circular or rectangular aluminum foil are bonded simultaneously on the surface. The size of the photo of the bird of prey, such as falcon, hawk, eagle, etc., may be large enough to cover the feathers of Kazaguruma, or at least 5 cm2. It is sufficient that the number of photographs to be bonded is one sheet or the number of feathers of kazaguruma. In addition, this Kazaguruma has a creative shape that scares birds such as crows, and the colors of its feathers are red, blue, yellow, green, black, white, etc., alone or in combination. Needless to say, the effect is doubled by installing several in the garden.
鳥類のメスはオスの羽根が放つ紫外線反射の強弱によってメスがオスを選択する際の判断基準になっており、健康なオスほどその羽根からの紫外線反射は強い。オスの求愛は羽根をそばだたせることにより行う紫外線反射を利用した求愛活動である。
また、鳥類は多くの果実の表面が成熟することによってテカテカと輝くことで紫外線反射を感知し、その網膜の吸収率によって果実が成熟したことを知るメカニズムになっている。ヒヨドリ等がリンゴの実をついばむのはその成熟化を紫外線吸収率に置き換えて検知しており、決して未成熟の青いリンゴは食しない。
リンゴの実を食するヒヨドリやカラスの天敵はハヤブサである。ハヤブサはヒヨドリを襲い、１日に２，３匹のヒヨドリを食する。ハヤブサはヒヨドリの羽根等の紫外線反射を検知し、また、ヒヨドリの糞、尿の紫外線反射からもその存在を嗅ぎ付け襲うのである。逆に言えば、ヒヨドリがハヤブサの羽根の紫外線反射を見つけるとハヤブサの存在を感知し近寄ってはこない。
本カザグルマは、自然の風がなく静止している時、任意枚の羽根の凸表面や凹表面及び平面上に接着した任意数のハヤブサ、タカ、ワシ等、猛禽類の写真やアルミ薄片に対する太陽光線の入射角が異なっており、その太陽光線の入射角に等しい反射角でもって可視光線や紫外線を反射している。即ち、任意数のハヤブサ、タカ、ワシ等、猛禽類の写真やアルミ薄片の位置に応じて太陽の位置と相まって反射方向が相違することになる。この反射方向は日中の、朝日が昇って日が沈むまでの太陽の位置によって、また春夏秋冬の地球の地軸の傾き角によっても微妙に可視光線や紫外線の反射方向が違うようになる。ましてや、カザグルマが静止した状態から自然の風の力を受けて回転すると、当該任意数のそれぞれのハヤブサ、タカ、ワシ等、猛禽類の写真やアルミ薄片に対する太陽光線からの反射方向は目まぐるしく変化し、カザグルマ自身は可視光線や紫外線の乱反射の回転体と化す。この回転中に太陽光線とアルミ箔の薄片が正対もしくは正対に近い位置にある時は鋭く可視光線や紫外線を反射することになる。このように、本発明のカザグルマが回転を始めると複数枚の羽根の凸表面や凹表面及び平面上に接着した任意数のハヤブサ、タカ、ワシ等、猛禽類の写真やアルミ薄片の中で、太陽光線を受ける位置にあるアルミ薄片の反射光線はそれぞれ方向を違え、強弱を違えて反射光を散乱させる。1日の間にも、春夏秋冬においてもそれは刻々変わっていく。カザグルマを回転させる風速がない場合でもその羽根が揺れるだけで反射光は微妙に変化するのである。カザグルマが回転もしくは揺動した方がヒヨドリ、カラス等は恐怖感を感じることは実験結果からも明らかである。
本カザグルマをリンゴ園の周囲、内部等ヒヨドリ等の目に検知できる位置に設置したとき、ヒヨドリ等はカザグルマの羽根表面のハヤブサの写真から発する紫外線反射からその存在を意識し決してリンゴ園には近寄ってこないのである。即ち、リンゴの成熟の１週間前程度から取り入れまでの期間に本カザグルマを１個ないし複数個設置することによりヒヨドリのリンゴ園への来襲を阻止できることになる。実験においてもこのことが証明されている。
以上から、1日単位においても、春夏秋冬どの季節においても刻々と変わる変化によって、ヒヨドリ、カラス等の学習能力を混乱せしめ、効率よく、合理的に、簡単な装置でもってヒヨドリ等の襲来を防止することができる。
Avian females are the criteria for female selection of males due to the intensity of ultraviolet reflections emitted by male wings. The more healthy males, the stronger the UV reflection from their wings. Male courtship is a courtship activity using ultraviolet reflection performed by putting out feathers.
In addition, birds have a mechanism that knows that the fruit has matured by the absorption rate of the retina because it senses UV reflection by shining with the categorization of the surface of many fruits. Bulbuls and the like pick the apple fruit by detecting its maturation by replacing it with UV absorption, and never eat an immature blue apple.
Peregrine falcons and crows that eat apple fruits are falcons. Peregrine falcon attacks the bullfinch and eats two or three buddies a day. Peregrine falcons detect UV reflections such as wings of buds, and sniff their presence from the reflections of chick dung and urine. In other words, if a chick finds an ultraviolet reflection from a falcon's feathers, it senses the presence of the falcon and does not approach it.
This Kazaguruma is a photo of a bird of prey such as falcons, hawks, eagle, etc. adhered to the convex or concave surface and plane of any number of wings when standing still without natural wind. The incident angles of light rays are different, and visible light rays and ultraviolet rays are reflected with a reflection angle equal to the incident angle of the sunlight. In other words, depending on the number of falcons, hawks, eagles and other birds of prey, and the position of the aluminum flakes, the reflection direction differs depending on the position of the sun. Depending on the position of the sun during the day until the sun rises and the sun goes down, and the inclination angle of the earth's earth axis in spring, summer, autumn and winter, the reflection direction of the visible light and ultraviolet light slightly changes. Moreover, when the Kazaguruma is rotated from a stationary state under the force of natural wind, the direction of reflection from the sun rays on the raptors such as falcons, hawks, eagle, etc. Kazaguruma itself turns into a rotating body of irregular reflection of visible light and ultraviolet rays. During this rotation, when the sunlight and the aluminum foil flakes are in the front or near the front, the visible light and ultraviolet rays are sharply reflected. Thus, when the kazaguruma of the present invention begins to rotate, any number of falcons, hawks, eagle, etc. adhered on the convex and concave surfaces and planes of the blades, among the pictures of raptors and aluminum flakes, The reflected rays of the aluminum flakes at the position where they receive sunlight are different directions, and the reflected light is scattered in different directions. It changes from day to day as well as spring, summer, autumn and winter. Even when there is no wind speed to rotate the kazaguruma, the reflected light changes subtly only by shaking the blade. It is clear from the experimental results that the fowl, crows, etc. feel fear when the kazaguruma rotates or swings.
When this Kazaguruma is installed in a position where it can be detected by the eyes such as the buds around the apple orchard, the chicks are conscious of their existence from the reflection of falcons on the surface of the feathers of Kazaguruma and never approach the apple orchard. It does not come. In other words, the installation of one or more kazaguruma during the period from about one week before apple maturation to the incorporation of the apple can prevent the bullock from attacking the apple orchard. This has been proved in experiments.
From the above, even in a single day, changes that change every moment in every season, such as spring, summer, and winter, disrupt the learning ability of chicks, crows, etc. Can be prevented.
本考案に基づく実施の形態について添付した図面に基づき説明する。本考案に係るカザグルマ装置は、１は羽根を表している。羽根は２円筒外表面に装着固定され、５揺動軸の設置地面と平行な軸部に挿入されその軸部から逸脱しないようコマ３および４によって軸方向の移動が制限されている。当該２円筒内径と５揺動軸外径とは適切なクリアランスを有している。５揺動軸の設置地面と鉛直軸部は９円筒に挿入され、鉛直方向の位置は５揺動軸に固定された６コマの下部に設けられた５揺動軸鉛直方向に自在に移動可能な７円板があり、５揺動軸は6コマ、７円板、９円筒の上部端面が重力により接するまで挿入される。当該９円筒内径と５揺動軸外径とは適切なクリアランスを有している。８は抜け止め用のコマであり、下方突風が吹いた時の脱落防止用のため設置される。簡易的には絶縁テープにて代用することは可能である。１０は設置地面に打ち込まれる竿、杭でありステイを介して９円筒と固定される。尚、５揺動軸はほぼ直角に曲げられているが、正確には、その角度は90度以上、100度以下の範囲である。この理由は強風が吹いた時、１羽根の先端が撓んで５揺動軸もしくは９鉛直円筒に接触し破壊するのを防止するためである。
Embodiments based on the present invention will be described with reference to the accompanying drawings. In the kazaguruma apparatus according to the present invention, reference numeral 1 denotes a blade. The blades are mounted and fixed on the outer surface of the two cylinders, inserted into the shaft portion parallel to the installation ground of the five swing shafts, and axial movement is restricted by the tops 3 and 4 so as not to deviate from the shaft portion. The two cylindrical inner diameters and the five swing shaft outer diameters have an appropriate clearance. The installation ground and vertical shaft of the 5 swing shaft are inserted into 9 cylinders, and the vertical position is freely movable in the vertical direction of the 5 swing shaft provided at the bottom of 6 frames fixed to the 5 swing shaft. There are 7 discs, 5 swinging shafts are inserted 6 frames, 7 discs, 9 until the upper end face of 9 cylinders touches by gravity. The 9 cylindrical inner diameter and the 5 rocking shaft outer diameter have an appropriate clearance. 8 is a retaining piece, and is installed to prevent falling off when a downward gust of wind blows. In simple terms, it is possible to substitute an insulating tape.
図１において、１カザグルマの羽根は５揺動軸の設置地面と平行に回転し、同時に５揺動軸は設置地面と鉛直方向円筒を中心に回転する。１羽根と正対する風が吹いた時は問題なく１羽根は回転するが、１羽根と正対しない風が吹いたとしてもその風が羽根に風力として作用し、５揺動軸を回転させる回転トルクとして働くため１羽根と風が正対するまで回転する。５揺動軸、１羽根を始めとした回転物の質量は小さく、従って摺動抵抗は極めて小さい。このことは微風であっても、この１羽根、5揺動軸は回転、もしくは揺動することを示している。 In FIG. 1, the blades of 1 kazaguruma rotate parallel to the installation ground of the 5 swing shafts, and at the same time, the 5 swing shafts rotate around the installation ground and the vertical cylinder. One wind rotates without any problem when a wind that faces one blade is blown, but even if a wind that does not face one blade blows, the wind acts as a wind force on the blade and rotates to rotate the five swing shafts. Since it acts as a torque, it rotates until one blade and the wind face each other. The mass of the rotating object including the 5 rocking shaft and 1 blade is small, and therefore the sliding resistance is extremely small. This indicates that even with a slight breeze, the one blade and the five swing shafts rotate or swing.
従来の人間界から見た鳥追い装置とは違い、鳥類の紫外線感知能力から追求した鳥追い装置であり、実験的にも確かめられており、りんご園、柿園だけでなく枇杷園等の果樹園、キャベツ、ブロッコリー、スイカ畑等の野菜畑、ゴミ集積所等に広く利用可能である。 Unlike the conventional bird chasing device seen from the human world, it is a bird chasing device pursued from the ability of birds to detect ultraviolet rays, and has been confirmed experimentally, not only apple orchards, but also orchards such as vineyards, cabbage It can be widely used in vegetable fields such as broccoli and watermelon fields, and garbage dumps.
