Description
本発明は、鳩、カラス等の鳥類の飛来を防止し、糞害や巣作りによる建物等の汚染、損傷を防止する装置に関する。 The present invention relates to an apparatus for preventing birds such as pigeons and crows from flying, and preventing contamination and damage to buildings due to dung damage and nesting.
鳥類の飛来に伴う様々な被害が近年大きな問題になっている。例えば、神社、仏閣においては、鳩の糞がこれらを汚染し、貴重な建造物の美観を損なうだけでなく、腐食問題を引き起こして保存管理に支障をきたす。また、観光客が鳥の落とす糞によって衣服の汚染等の害を被ることも多い。このような事情は、居住用住宅や工場、倉庫等においても同じである。 Various damages caused by the arrival of birds have become a major problem in recent years. For example, in shrines and temples, pigeon dung pollutes them, not only detracting from the beauty of precious buildings, but also causes corrosion problems that impede conservation management. In addition, tourists often suffer from damage such as clothes contamination by droppings dropped by birds. This situation is the same in residential houses, factories, warehouses, and the like.
上記のような鳥害を防止するには、鳥類の飛来そのものを防ぐ対策が必要である。ネットを張って鳥の侵入を阻むのは、その対策の一つであるが、それには大がかりな工事が必要であり、かつ、ネット自体が建物の美観を損なうという難点がある。 In order to prevent bird damage as described above, it is necessary to take measures to prevent birds from flying. One of the measures to prevent the invasion of birds by setting up a net is a large-scale construction, and the net itself impairs the beauty of the building.
通電した金属線を張り巡らせて、それに触れた動物に電気的ショックを与え、田畑への侵入を防止する技術は広く知られている。その原理を鳥類の飛来防止に利用することも下記の特許文献１〜３によって提案されている。 A technique for stretching an energized metal wire and applying an electric shock to an animal that touches the metal wire to prevent entry into a field is widely known. The use of this principle to prevent birds from flying has also been proposed by the following Patent Documents 1 to 3.
特許文献１では張架台に設けた孔に導線を通して保持する装置が提案されている。この装置では、導線は上記の孔に通されてからボルト等で固定されるので、導線が大気温度の変化で膨脹、収縮を繰り返すと張架台に応力がかかり、設置面から剥離してしまう。特許文献２（特開２０００−３２９０１号公報）に開示されているのも張架台に設けた孔に導線を通してこれを固定する方式の装置である。その装置にも特許文献２の装置と同様の欠点がある。これらに共通するのは、導線に張力を与えて弛みを防ぐのが必須であるという思想であり、そのために導線を張架台に固定することとしているのである。
Patent Document 1 proposes a device that holds a lead wire through a hole provided in a stretcher. In this apparatus, since the conducting wire is fixed with a bolt or the like after passing through the hole, if the conducting wire repeatedly expands and contracts due to a change in the atmospheric temperature, stress is applied to the gantry and peels off from the installation surface. Patent Document 2 (Japanese Patent Application Laid-Open No. 2000-32901) also discloses a device of a type that fixes a wire through a hole provided in a stretcher base. The apparatus has the same drawbacks as the apparatus of
特許文献３に開示されている装置は、固定器具に設けた溝に導線を嵌め込んで設置し、導線に触れた鳥類に電気的ショックを与えるものである。この装置では、導線は溝に嵌め込むだけであるから、設置作業は簡易である。しかし、溝に嵌め込んだだけの導線は、わずかな外力ではずれやすく、外れ落ちた導線は役に立たないから、装置が長期使用に耐えないという大きな難点がある。
The device disclosed in
本発明の目的は、これまでに提案されている鳥類飛来防止装置の欠点を無くし、設置作業が簡単で、しかも設置後の破損が起きにくく耐久性に富んだ鳥類の飛来防止装置を提供することにある。 An object of the present invention is to provide a bird flying prevention device that eliminates the disadvantages of the bird flying prevention devices that have been proposed so far, is easy to install, and is less likely to be damaged after installation and has high durability. It is in.
本発明は、導電体として剛性の大きな硬質金属製のものを使用すれば、導線を担持体に固定する必要がないという知見に基づき、そのような伝導体の担持方法を改良してなされた。本発明の鳥類の飛来防止装置は、下記のとおりのものである。 The present invention has been made by improving the method for supporting such a conductor based on the knowledge that if a conductor made of a hard metal having high rigidity is used, it is not necessary to fix the conductive wire to the carrier. The birds flying prevention apparatus of the present invention is as follows.
硬質の金属棒からなる２本以上の導電体と、それを担持する２個以上の絶縁性担持体とを備えた鳥類の飛来防止装置であって、下記(1)から(3)までを特徴とする鳥類の飛来防止装置。
A bird flying prevention device comprising two or more conductors made of hard metal rods and two or more insulating carriers for supporting the conductors , characterized by the following (1) to (3) An anti-flight device for birds .
(1)上記絶縁性担持体は、合成ゴム製で、その形状が側面視Ｌ形で、そのＬ形を構成するいずれか１辺に２個以上の貫通孔、または各１辺にそれぞれ１個以上の貫通孔が設けられたものであること。
(2)導電体となる金属棒が直径1.5〜3.0mmのバネ用ステンレス鋼棒であること。
(3)所定位置に間隔をおいて設置された上記絶縁性担持体の間に、上記貫通孔中に摺動可能に挿通された前記導電体が配設されていること。
(1) The insulating carrier is made of synthetic rubber and has an L shape when viewed from the side, and has two or more through holes on any one side of the L shape, or one on each side. The above through holes are provided .
(2) The metal rod used as the conductor is a stainless steel rod for springs with a diameter of 1.5 to 3.0 mm .
(3) The conductors slidably inserted into the through-holes are disposed between the insulating carriers disposed at predetermined positions at intervals .
本発明の装置は、設置が容易で、しかも導電体に膨脹、収縮が生じても担持体にその影響を及ぼさない。従って、長期の使用に耐える耐久性に富むものである。 The device of the present invention is easy to install, and even if the conductor expands or contracts, it does not affect the carrier. Therefore, it is rich in durability to withstand long-term use.
以下、図面に示す具体例よって本発明の装置を説明する。 Hereinafter, the apparatus of the present invention will be described with reference to specific examples shown in the drawings.
図１は、絶縁性担持体の形状、寸法を説明するための図であり、(A)は側面図、(B)は正面図、即ち、(A)図の矢印方向から見た図である。図１の(A)に示すように、担持体１は側面視がＬ形である。そして、Ｌ形を構成する各辺２、３には貫通孔4-1〜4-5がある。なお、図示の例では、各辺の端部2-1および3-1が斜めに切断されていて切断面には微細な凹凸が設けてある。これは、後述する図２のように設置する場合、設置面に接着剤等で固定するときに接着をより強固にするためである。
FIG. 1 is a diagram for explaining the shape and dimensions of an insulating carrier, in which (A) is a side view, (B) is a front view, that is, a view seen from the direction of the arrow in FIG. . As shown in FIG. 1A, the carrier 1 is L-shaped in side view. And there are through holes 4-1 to 4-5 in the
担持体１は、絶縁性の材料でなければならない。また、長期間、太陽光や風雨にさらされることが多いので、耐候性のある材料が望ましい。加工性や価格をも考慮すれば、合成ゴムが好適である。 The carrier 1 must be an insulating material. Moreover, since it is often exposed to sunlight or wind and rain for a long time, a weather-resistant material is desirable. In consideration of processability and price, synthetic rubber is preferable.
図１に示す例では、辺２の長さL１が60mm、辺３の長さL２が45mmである。貫通孔の間隔は、それに挿通した金属棒の２本を鳥が両足で掴むことができる間隔にする。従って、その間隔は、飛来を防ぎたい鳥の種類に応じて選定すればよい。図示の例では、孔4-1と4-3の間隔が35mm、孔4-2と4-3の間隔が20mm、孔4-3と4-4の間隔が20mm、孔4-3と4-5の間隔が30mmである。このようにしておけば、大きさの異なる鳥にも対応できる。
In the example shown in FIG. 1, the length L 1 of the
各辺２、３は所定の厚みｔを有する。孔は厚みのほぼ中央に設けるのがよい。図示の例ではｔは8.5mmである。また、辺の幅Ｗは20mmである。
貫通孔は、Ｌ形を構成するいずれか１辺だけに設けてもよい。その場合は２個以上とする。また、それぞれの辺に各１個以上の貫通孔を設けてもよい。いずれの場合も貫通孔の総計は２個以上とする必要がある。なお、貫通孔が３個以上の場合に、これらの孔の全てに金属棒を挿通する必要はなく、これらの孔の任意の複数の孔に金属棒を挿通してもよい。
Each
You may provide a through-hole only in any one side which comprises L shape. In that case, two or more. One or more through holes may be provided on each side. In either case, the total number of through holes must be two or more. In addition, when there are three or more through holes, it is not necessary to insert the metal rods into all of these holes, and the metal rods may be inserted into any of a plurality of these holes.
言うまでもなく、担持体の大きさは図示のものに限られない。設置場所や飛来防止の対象鳥類に応じて、大きさを変えればよい。また、両辺の長さを同一にしてもよく、両辺のなす角度（θ）も必ずしも90°でなくてもよい。例えば、60°〜120°の範囲で選べばよい。 Needless to say, the size of the carrier is not limited to that illustrated. What is necessary is just to change a magnitude | size according to the installation place and the bird for prevention of flying. Further, the lengths of both sides may be the same, and the angle (θ) formed by both sides is not necessarily 90 °. For example, it may be selected in the range of 60 ° to 120 °.
図２は、本発明装置の一例の設置状態を示す斜視図である。図示のとおり、担持体１は、例えば60cmの間隔をもって、設置面に接着剤等で固定される。その貫通孔4-1、4-2、4-3・・・には、導電性の金属棒5-1、5-2および5-3・・・が挿通される。図２には３個の貫通孔に金属棒を挿通した例を示した。
貫通孔4-1、4-2、4-3・・・の直径は、金属棒が貫通孔の中で摺動できるようにするため、金属棒の直径よりもやや大きくする。ただし、むやみに大きくすると金属棒がガタついて不安定になるので、金属棒の直径より0.1〜1.5mm程度大きい直径とするのがよい。
金属棒は、硬質の金属で作られている。この金属棒は、貫通孔に挿通されるが、上記のとおりその径が貫通孔の径より小さいので、かりに金属棒に引張力がかかっても孔の中で自由に滑ることができる。即ち、金属棒の軸方向に生じた応力によって担持体１に力がかかることはない。従って、気温の変化等によって金属棒に膨脹や収縮が生じてもそれによって担持体に力がかかって設置面からはがれて転倒するようなことはない。
FIG. 2 is a perspective view showing an installation state of an example of the device of the present invention. As illustrated, the carrier 1 is fixed to the installation surface with an adhesive or the like with an interval of 60 cm, for example. The conductive metal rods 5-1, 5-2, 5-3,... Are inserted through the through holes 4-1, 4-2, 4-3,. FIG. 2 shows an example in which a metal rod is inserted into three through holes.
The diameters of the through holes 4-1, 4-2, 4-3,... Are slightly larger than the diameter of the metal bar so that the metal bar can slide in the through hole. However, if the size is increased excessively, the metal rod will become unstable and unstable, so the diameter should be about 0.1 to 1.5 mm larger than the diameter of the metal rod.
The metal bar is made of hard metal. This metal rod is inserted into the through-hole. Since the diameter thereof is smaller than the diameter of the through-hole as described above, the metal rod can slide freely in the hole even if a tensile force is applied to the metal rod. That is, no force is applied to the carrier 1 due to the stress generated in the axial direction of the metal rod. Therefore, even if the metal rod expands or contracts due to a change in temperature or the like, it does not force the carrier to peel off from the installation surface and fall down.
金属棒は、例えばSUS304等のバネ用ステンレス鋼であることが望ましい。ステンレス鋼は耐食性に優れ、長期間の使用でも錆びることがなく、導電性を失うこともない。金属棒の直径は、1.5〜３mmの範囲で選定すればよい。 The metal rod is preferably made of stainless steel for springs such as SUS304. Stainless steel has excellent corrosion resistance, does not rust even after long-term use, and does not lose electrical conductivity. What is necessary is just to select the diameter of a metal rod in the range of 1.5-3 mm.
金属棒の一端は電源（図示せず）に導線で接続される。例えば、金属棒5-1は正極に、金属棒5-2と5-3は負極に接続される。従って、鳥が金属棒5-1と5-2または5-1と5-3を片方づつの足で掴めば、その瞬間に体内に電気が流れて、そのショックで鳥は逃げ去る。なお、金属棒の他端は、固定する必要がない。 One end of the metal bar is connected to a power source (not shown) by a conductive wire. For example, the metal rod 5-1 is connected to the positive electrode, and the metal rods 5-2 and 5-3 are connected to the negative electrode. Therefore, if a bird grabs the metal rods 5-1 and 5-2 or 5-1 and 5-3 with one leg, electricity will flow into the body at that moment, and the bird will escape by the shock. It is not necessary to fix the other end of the metal bar.
金属棒は硬質金属製であるから、担持体の孔に挿通しやすく、取付作業は容易である。金属棒の硬さは、鳥の重量がかかっても大きなたわみが生じない程度の剛性を金属棒が持つように選定すればよい。図示の例では各貫通孔の径を３mmとし、これに径２mmのSUS304のバネ用ステンレス鋼の棒を挿入している。 Since the metal rod is made of hard metal, it can be easily inserted into the hole of the carrier and the mounting operation is easy. The hardness of the metal rod may be selected so that the metal rod has a rigidity that does not cause a large deflection even when the weight of the bird is applied. In the illustrated example, the diameter of each through hole is 3 mm, and a stainless steel rod for spring of SUS304 having a diameter of 2 mm is inserted into this.
金属棒としては、通常は、取り扱いに便利な約２m程度のものを使用する。これをおよそ40〜100cmの間隔をおいて設置された担持体の孔に挿通していく。長い距離にわたって設置する場合には、金属棒の両端部を図３に示すようなバネ鋼製のスプリング６で連結していけばよい。このスプリングの内径を金属棒の径とほぼ同じにしておけば、一旦その内部に嵌め込んだ金属棒は、引き抜く方向に張力をかけても容易にははずれない。また、このスプリングの位置で湾曲させることができるので、曲線状に金属棒を張り巡らすのにも好都合である。
As a metal rod, a metal rod of about 2 m that is convenient for handling is usually used. This is inserted through the holes of the carrier installed at an interval of approximately 40-100 cm. In the case of installation over a long distance, both ends of the metal rod may be connected by
設置に際しては、正極に接続した金属棒と負極に接続した金属棒とは隣り合うようにするのが望ましい。なお、金属棒の間隔を近づけすぎるとスパークして放電損失が生じる。スパーク防止には、一般に、1000Ｖごとに１mm以上の間隔が必要とされるので、負荷する電圧に応じて最小間隔が決まる。 When installing, it is desirable that the metal bar connected to the positive electrode and the metal bar connected to the negative electrode be adjacent to each other. Note that if the distance between the metal rods is too close, sparking occurs and discharge loss occurs. In order to prevent sparks, an interval of 1 mm or more is generally required for every 1000 V, so the minimum interval is determined according to the voltage applied.
前記のように金属棒の一端は電源（バッテリー）に接続されるが、他端は特に固定しないままでよい。電源は市販のバッテリーでよく、例えば自動車用のバッテリーも使用できる。電源としては、高電圧パルス（パルス電圧が5,000〜10,000Ｖのもの）の発生回路を有するものを使用するのがよい。例えば、約１秒の周期で高電圧のパルスを発信するものが望ましい。 As described above, one end of the metal rod is connected to the power source (battery), but the other end may be left unfixed. The power source may be a commercially available battery. For example, a battery for automobiles can also be used. As the power source, it is preferable to use a power source having a circuit for generating a high voltage pulse (having a pulse voltage of 5,000 to 10,000 V). For example, it is desirable to transmit a high voltage pulse with a period of about 1 second.
以上、本発明の望ましい態様を説明した。図１に示した形状の担持体は、図２に示す態様だけでなく、例えばＬの一辺を設置面に固定してもよい。その場合にも２本の金属棒を鳥が掴みやすくなるように貫通孔の位置を決める。 The preferred embodiments of the present invention have been described above. The carrier having the shape shown in FIG. 1 is not limited to the mode shown in FIG. 2, and for example, one side of L may be fixed to the installation surface. Even in that case, the position of the through hole is determined so that the two metal bars can be easily grasped by the bird.
本発明の装置は、どのような場所にも容易に取り付けることができる。担持体は接着剤で固定できるので、取付が容易で、既存の建物等に傷をつけることなく施工することができる。しかも、ネットや柵のように目立つこともないので、建物等の美観を損なうこともない。また、例えば野外の特定の場所で一定の時間だけ鳥の飛来を防ぎたい場合などには、本発明装置をその場所に臨時に設置することもできる。 The device of the present invention can be easily installed anywhere. Since the carrier can be fixed with an adhesive, it is easy to install and can be constructed without damaging existing buildings. Moreover, since it does not stand out like a net or a fence, it does not impair the beauty of the building. In addition, for example, when it is desired to prevent a bird from flying for a certain period of time at a specific place in the field, the apparatus of the present invention can be temporarily installed at that place.
本発明の装置に触れて電気的なショックを受けた鳥は、以後、この装置の近辺には寄りつかなくなる。従って、前述した鳥の飛来による様々な被害をきわめて効果的に防止することができる。 Birds that have received an electrical shock by touching the device of the present invention will no longer be able to approach the device. Therefore, various damages caused by the above-mentioned bird flight can be prevented very effectively.
