Description

本発明は、鳥類営巣防止具に関する。 The present invention relates to a bird's nest prevention device.

従来、上方突出状の複数本の針を、複数列に配設して、電柱や鉄塔に設置し、鳥類の駐鳥を防止するものがあった（例えば特許文献１参照）。 Conventionally, there has been one in which a plurality of needles protruding upward are arranged in a plurality of rows and installed on a utility pole or a steel tower to prevent birds from being parked (see, for example, Patent Document 1).

特開昭６１－２３９８３２号公報Japanese Unexamined Patent Publication No. 61-239832

しかし、カラス等の鳥類は、巣作りする際に、巣の材料となる小枝等の巣材を上方から落下（投下）させるため、駐鳥を防止するための従来の上記複数列の針を具備する構成では、巣材が針に引っ掛かって、営巣されるという問題があった。 However, birds such as crows are equipped with the conventional multi-row needles to prevent bird parking in order to drop (drop) nest materials such as twigs, which are the materials for nests, from above when building nests. In this configuration, there is a problem that the nest material is caught by the needle and nests.

そこで、本発明は、駐鳥を防止しつつ、営巣を確実に防止可能な鳥類営巣防止具の提供を目的とする。 Therefore, an object of the present invention is to provide a bird nesting preventive device capable of reliably preventing nesting while preventing bird nesting.

本発明の鳥類営巣防止具は、上方突出状の複数本の針と、該複数本の針の基端部を連結する細長状の基端連結部と、を絶縁性樹脂で一体状に成形した鳥類営巣防止具であって、上記複数本の針が、上記基端連結部の長手方向に沿って１列のみ列設されており、隣り合う上記針の上下中間部を相互に連結する中間連結杆部を有し、複数本の上記中間連結杆部は、側面視で千鳥状に配設されているものである。
また、上記中間連結杆部は、横断面円形状であって、直径寸法を２ｍｍ以上４ｍｍ以下に設定したものである。
また、上記基端連結部の設置裏面から上記針の先端までの高さ寸法を、１７０ｍｍ以上２３０ｍｍ以下に設定し、上記針の先端から上記中間連結杆部までの上下寸法を、８０ｍｍ以上１５０ｍｍ以下に設定したものである。 In the bird's nest prevention device of the present invention, a plurality of upwardly projecting needles and an elongated base end connecting portion connecting the proximal ends of the plurality of needles are integrally molded with an insulating resin. A bird's nest prevention device in which the plurality of needles are arranged in only one row along the longitudinal direction of the proximal end connecting portion, and an intermediate connection is provided to connect the upper and lower intermediate portions of the adjacent needles to each other. The plurality of intermediate connecting rod portions having a rod portion are arranged in a staggered manner in a lateral view.
Further, the intermediate connecting rod portion has a circular cross-sectional shape, and the diameter dimension is set to 2 mm or more and 4 mm or less.
Further, the height dimension from the installation back surface of the base end connecting portion to the tip of the needle is set to 170 mm or more and 230 mm or less, and the vertical dimension from the tip of the needle to the intermediate connecting rod portion is 80 mm or more and 150 mm or less. It is set to.

本発明によれば、カラス等の鳥類が巣作りする際に、小枝等の棒状の巣材が上方から落下（投下）されても、針に巣材が引っ掛かるのを防止できる。つまり、針によって駐鳥を防止しつつ、営巣を確実に防止できる。 According to the present invention, when a bird such as a crow nests, even if a rod-shaped nest material such as a twig is dropped (dropped) from above, the nest material can be prevented from being caught by the needle. In other words, the needle can prevent bird nesting while reliably preventing nesting.

本発明に係る鳥類営巣防止具の実施の一形態を示す斜視図である。It is a perspective view which shows one embodiment of the bird nesting prevention device which concerns on this invention. 拡大斜視図である。It is an enlarged perspective view. 側面図である。It is a side view. 正面図である。It is a front view. 平面図である。It is a plan view. 底面図である。It is a bottom view.

以下、図示の実施形態に基づき本発明を詳説する。
本発明に係る鳥類営巣防止具は、図１乃至図５に示すように、上方突出状の複数本の針１と、複数本の針１の基端部を連結する細長状の基端連結部２と、を絶縁性樹脂で一体成形している。 Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
As shown in FIGS. 1 to 5, the bird nest prevention device according to the present invention has an elongated base end connecting portion that connects a plurality of upwardly projecting needles 1 and a base end portion of the plurality of needles 1. 2 and 2 are integrally molded with an insulating resin.

そして、複数本の針１が、基端連結部２の長手方向（前後方向）Ｎに沿って、１列のみ列設されている。複数本の針１は、幅方向同位置（左右方向同位置）に配設されており、図４のように正面視で１本に（重なって）見える。即ち、平面視一直線上に、複数本の針１が列設されている。 Then, a plurality of needles 1 are arranged in only one row along the longitudinal direction (front-back direction) N of the proximal end connecting portion 2. The plurality of needles 1 are arranged at the same position in the width direction (same position in the left-right direction), and can be seen as one (overlapping) in the front view as shown in FIG. That is, a plurality of needles 1 are arranged in a row on a straight line in a plan view.

さらに、隣り合う針１，１の上下中間部を相互に連結する中間連結杆部３を有している。中間連結杆部３は、隣り合う針１，１を長手方向Ｎに連結するように、針１と針１の間に１本ずつ設けられている。中間連結杆部３は、全体として長手方向Ｎに沿って複数本設けている。中間連結杆部３は、側面視で、針１の針軸心に直交状（設置面Ｇが水平面状の場合において水平状）に設けている。 Further, it has an intermediate connecting rod portion 3 for connecting the upper and lower intermediate portions of the adjacent needles 1 and 1 to each other. The intermediate connecting rod portion 3 is provided one by one between the needle 1 and the needle 1 so as to connect the adjacent needles 1 and 1 in the longitudinal direction N. A plurality of intermediate connecting rod portions 3 are provided along the longitudinal direction N as a whole. The intermediate connecting rod portion 3 is provided so as to be orthogonal to the needle axis of the needle 1 (horizontally when the installation surface G is a horizontal plane) in a side view.

カラス等の鳥類が巣作りする際に、巣の材料となる小枝等の棒状の巣材を上方から落下（投下）させた場合に、中間連結杆部３は、落下してくる巣材が設置面Ｇや基端連結部２に到達する前に、（先に）接触して、巣材を左右外方へ滑落させて（はじいて）、設置面Ｇ上や基端連結部２上に堆積するのを防止する。 When a bird such as a crow makes a nest, when a rod-shaped nest material such as a twig that is a material for the nest is dropped (dropped) from above, the falling nest material is installed in the intermediate connecting rod portion 3. Before reaching the surface G or the base end connecting portion 2, contact (first), the nest material is slid (flicked) outward to the left and right, and deposited on the installation surface G or the base end connecting portion 2. Prevent it from happening.

さらに、隣り合う針１と針１の間に、雪が降ってくる際に、中間連結杆部３によって、雪が左右方向（幅方向）Ｗに分離した雪の塊となって、左右外方に滑落しやすい。また、針１と針１の間に、一旦、堆積した雪の塊が中間連結杆部３によって、左右方向Ｗに分割されて、滑落しやすい。このように、中間連結杆部３が存在することによって、雪の塊が大きくなることを防止できる。
また、針列が１列のため、針列を複数列設けた場合と比べて、針１が、雪の滑落を邪魔しない（積雪の成長を助けない）。 Further, when snow falls between the adjacent needles 1 and 1, the intermediate connecting rod portion 3 makes the snow a mass of snow separated in the left-right direction (width direction) W and slides outward to the left and right. It's easy to do. Further, the snow mass once accumulated between the needle 1 and the needle 1 is divided in the left-right direction W by the intermediate connecting rod portion 3 and easily slides down. As described above, the presence of the intermediate connecting rod portion 3 can prevent the snow mass from becoming large.
Further, since the needle row is one row, the needle 1 does not interfere with the sliding of snow (it does not help the growth of snow) as compared with the case where a plurality of needle rows are provided.

中間連結杆部３は、横断面円形状であって、直径寸法ｄ（図３参照）を２ｍｍ以上４ｍｍ以下に設定している。
２ｍｍ未満であると、雪の左右方向Ｗへの（上述の）分離・分割の作用が得られなくなる。さらに、樹脂成型が困難になると共に、製品搬送中や施工中等に変形や破損する虞れがある。４ｍｍを超えると、鳥類が脚で掴みやすくなって、駐鳥される虞れがある。 The intermediate connecting rod portion 3 has a circular cross-sectional shape, and the diameter dimension d (see FIG. 3) is set to 2 mm or more and 4 mm or less.
If it is less than 2 mm, the action of separating / dividing the snow in the left-right direction W (described above) cannot be obtained. Further, resin molding becomes difficult, and there is a risk of deformation or damage during product transportation, construction, or the like. If it exceeds 4 mm, it becomes easier for birds to grasp with their legs, and there is a risk that they will be parked.

そして、複数本の中間連結杆部３は、側面視で、上下の千鳥状に配設している。長手方向Ｎに隣り合う一方の中間連結杆部３（３Ａ）の上下位置と、他方の中間連結杆部３（３Ｂ）の上下位置とを、相違させている。鳥類の一方の脚が、一方の中間連結杆部３（３Ａ）を掴み、鳥類の他方の脚が、他方の中間連結杆部３（３Ｂ）を掴もうとしても、高さ（上下位置）が異なり、姿勢が不安定になるため、鳥類が本能的に嫌がって、駐鳥を防止する。 The plurality of intermediate connecting rods 3 are arranged in an upper and lower staggered manner in a side view. The vertical position of one intermediate connecting rod portion 3 (3A) adjacent to each other in the longitudinal direction N is different from the vertical position of the other intermediate connecting rod portion 3 (3B). Even if one leg of the bird grabs one intermediate connecting rod 3 (3A) and the other leg of the bird tries to grab the other intermediate connecting rod 3 (3B), the height (upper and lower position) is high. Unlike, the posture becomes unstable, so birds instinctively dislike it and prevent it from being parked.

また、図３に示すように、一方の中間連結杆部３Ａ（の上縁３ａ）から他方の中間連結杆部３Ｂ（の上縁３ａ）までの上下段差寸法Δｈは、１５ｍｍ以上３０ｍｍ以下に設定するのが望ましい。１５ｍｍ未満であると駐鳥される虞れが高まる。３０ｍｍを超えると、一方（上位置の）中間連結杆部３Ａが、針１の先端11に接近し過ぎて針１による駐鳥防止効果が弱くなる。或いは、他方（下位置の）中間連結杆部３Ｂが、設置面Ｇに接近し過ぎて、落下してくる巣材が、下位置の中間連結杆部３Ｂに当接する前に、設置面Ｇに当接して、巣材が設置面Ｇと下位置の中間連結杆部３Ｂとによって傾斜状に引っ掛かって残存する虞れがある。 Further, as shown in FIG. 3, the vertical step dimension Δh from one intermediate connecting rod portion 3A (upper edge 3a) to the other intermediate connecting rod portion 3B (upper edge 3a) is set to 15 mm or more and 30 mm or less. It is desirable to do. If it is less than 15 mm, the risk of being parked increases. If it exceeds 30 mm, one of the intermediate connecting rods 3A (at the upper position) is too close to the tip 11 of the needle 1, and the effect of preventing the bird from being trapped by the needle 1 is weakened. Alternatively, the other (lower position) intermediate connecting rod 3B is too close to the installation surface G, and the falling nest material comes into contact with the installation surface G before the falling nest material comes into contact with the lower intermediate connecting rod 3B. There is a possibility that the nest material may be in contact with the installation surface G and the intermediate connecting rod portion 3B at the lower position to be caught in an inclined manner and remain.

さらに、基端連結部２の設置裏面２ｂから針１の先端11までの高さ寸法Ｈを、１７０ｍｍ以上２３０ｍｍ以下に設定し、針１の先端11から中間連結杆部３（の上縁３ａ）までの上下寸法ｈを、８０ｍｍ以上１５０ｍｍ以下に設定している。 Further, the height dimension H from the installation back surface 2b of the base end connecting portion 2 to the tip 11 of the needle 1 is set to 170 mm or more and 230 mm or less, and the intermediate connecting rod portion 3 (upper edge 3a) from the tip 11 of the needle 1 is set. The vertical dimension h up to is set to 80 mm or more and 150 mm or less.

高さ寸法Ｈが１７０ｍｍ未満であると、鳥類に対する威嚇（忌避）効果が弱まる。２３０ｍｍを超えると製造や搬送や施工の取扱いが困難になって使い勝手が悪くなる。
また、上下寸法ｈを８０ｍｍ未満にすると、中間連結杆部３を掴もうとする鳥類に針１の先端11が接触しにくくなって、駐鳥防止効果が弱まる。また、１５０ｍｍを超えると、設置面Ｇに接近し過ぎて、落下してくる巣材が、中間連結杆部３に当接する前に、設置面Ｇに当接して、巣材が設置面Ｇと中間連結杆部３とによって傾斜状に引っ掛かって残存する虞れがある（巣材が堆積する虞れが高まる）。 If the height dimension H is less than 170 mm, the threatening (repellent) effect on birds is weakened. If it exceeds 230 mm, it becomes difficult to manufacture, transport, and handle the construction, and the usability deteriorates.
Further, when the vertical dimension h is less than 80 mm, the tip 11 of the needle 1 is less likely to come into contact with the bird trying to grip the intermediate connecting rod portion 3, and the effect of preventing bird parking is weakened. Further, if it exceeds 150 mm, the nest material comes into contact with the installation surface G before the nest material that falls too close to the installation surface G abuts on the intermediate connecting rod portion 3, and the nest material comes into contact with the installation surface G. There is a possibility that it will be caught in an inclined shape by the intermediate connecting rod portion 3 and remain (the possibility that the nest material will be deposited increases).

また、長手方向Ｎに隣り合う針１と針１の間の間隔寸法Ｋは、２０ｍｍ以上４０ｍｍ以下に設定している。
２０ｍｍ未満であると、針１同士が接近し過ぎて、威嚇効果が低下すると共に、巣材が引っ掛かる虞れが高くなる。４０ｍｍを超えると、針１同士の間隔が開きすぎて、針１と針１の間に鳥類（の頭）が侵入しやすくなって駐鳥される虞れが高くなる。 Further, the distance dimension K between the needles 1 adjacent to each other in the longitudinal direction N is set to 20 mm or more and 40 mm or less.
If it is less than 20 mm, the needles 1 come too close to each other, the threatening effect is reduced, and the risk of the nest material being caught increases. If it exceeds 40 mm, the distance between the needles 1 becomes too wide, and it becomes easy for birds (heads) to invade between the needles 1 and the risk of being parked increases.

また、針１は、基端（下部）から先端（上部）11に次第に縮径するテーパ状に形成され、頂部が丸山型に形成されている。
また、テーパ状の針１は、基端部から上下中間所定位置までの上下所定領域（部位）は、上下方向に沿った複数本の溝部12が形成されている。溝部12は、平面視（図５参照）で、針軸心廻りに等間隔に４つ配設されている。つまり、針１は、上下所定領域の横断面形状を十字状に形成している。また、上下所定領域よりも上位置の上部領域は、横断面を、円形状に形成している。 Further, the needle 1 is formed in a tapered shape in which the diameter is gradually reduced from the base end (lower part) to the tip end (upper part) 11, and the top portion is formed in a round mountain shape.
Further, in the tapered needle 1, a plurality of groove portions 12 are formed along the vertical direction in the upper and lower predetermined regions (sites) from the base end portion to the upper and lower intermediate predetermined positions. Four groove portions 12 are arranged at equal intervals around the center of the needle axis in a plan view (see FIG. 5). That is, the needle 1 has a cross-shaped cross-sectional shape in the upper and lower predetermined regions. Further, the upper region above the upper and lower predetermined regions has a circular cross section.

また、基端連結部２は、電柱や鉄塔等の電力設備（送電設備）において駐鳥や営巣を防止すべき面（駐鳥営巣防止面）Ｇに、固着される部位であって、平面視で、魚の骨型である。
図１乃至図６に示すように、基端連結部２は、複数本の針１の基端部を連結する一直線状（一本状）の縦杆部21と、縦杆部21から幅方向外方へ（左右外方へ）夫々に突出する横脚杆部22と、長手方向Ｎに隣り合う横脚杆部22，22の間に配設され縦杆部21から左右外方へ夫々突出する平面視矩形状のブロック型の補強脚部23と、を備えている。 Further, the base end connecting portion 2 is a portion fixed to a surface (bird nesting prevention surface) G in which bird parking and nesting should be prevented in electric power equipment (power transmission equipment) such as utility poles and steel towers, and is viewed in a plan view. And it is a fish bone type.
As shown in FIGS. 1 to 6, the proximal end connecting portion 2 has a linear (single) vertical rod portion 21 for connecting the proximal end portions of a plurality of needles 1 and a width direction from the vertical rod portion 21. It is arranged between the horizontal leg rods 22 protruding outward (to the left and right outward) and the horizontal leg rods 22 and 22 adjacent to each other in the longitudinal direction N, and protrudes outward from the vertical rod 21 respectively. It is provided with a block-shaped reinforcing leg portion 23 having a rectangular shape in a plan view.

左右一対の横脚杆部22，22は、複数本の各針１に夫々対応するように、針１と長手方向Ｎの位置を対応（一致）させて、突風等による針１の横倒れを防止する。また、長手方向Ｎに隣り合う横脚杆部22，22の先端部を相互に連結する横脚先端連結部を有していない（省略している）ので、設置面（駐鳥営巣防止面）Ｇの幅寸法が小さく、横脚杆部22の先端部が、設置面Ｇから突出した場合であっても、駐鳥される虞れがない。 The pair of left and right horizontal leg rods 22, 22 correspond (match) the positions of the needle 1 and the longitudinal direction N so as to correspond to each of the plurality of needles 1, so that the needle 1 falls sideways due to a gust or the like. To prevent. In addition, since it does not have a horizontal leg tip connecting portion (omitted) that connects the tips of the horizontal leg rods 22 and 22 adjacent to each other in the longitudinal direction N (omitted), the installation surface (bird nesting prevention surface). Even if the width dimension of G is small and the tip of the horizontal leg rod portion 22 protrudes from the installation surface G, there is no possibility that birds will be parked.

左右一対の補強脚部23，23は、長手方向Ｎの位置を、針１と針１の間に対応（一致）させている。補強脚部23は、横脚杆部22よりも幅方向寸法（左右突出寸法）を短く設けている。また、横脚杆部22よりも長手方向寸法（前後方向寸法）を大きく設けて、扁平形状とし、駐鳥防止面との接触面積を増加させて倒れや位置ズレを防止している。 The pair of left and right reinforcing legs 23, 23 correspond (match) the position in the longitudinal direction N between the needle 1 and the needle 1. The reinforcing leg portion 23 is provided with a width direction dimension (left-right protruding dimension) shorter than that of the horizontal leg rod portion 22. In addition, the longitudinal dimension (front-back dimension) is larger than that of the horizontal leg rod 22 to form a flat shape, and the contact area with the bird-parking prevention surface is increased to prevent falling or misalignment.

なお、基端連結部２を、電柱や鉄塔の腕金の上面等の設置面Ｇに固定（固着）する手段は、基端連結部２（縦杆部21や横脚杆部22）を下方から抱き込み状に保持する金具（取付具）を介してネジ止めする固定や、コの字状のクランプ金具（取付具）による固定、粘着テープ、接着剤、樹脂製の結束バンド（取付具）等による固定等自由である。 The means for fixing (fixing) the base end connecting portion 2 to the installation surface G such as the upper surface of the utility pole or the arm metal of the steel tower is to lower the base end connecting portion 2 (vertical rod portion 21 or horizontal leg rod portion 22). Fixing by screwing via a metal fitting (attachment) that holds it in a hug shape, fixing with a U-shaped clamp metal fitting (attachment), adhesive tape, adhesive, resin binding band (attachment) It is free to fix by such as.

また、基端連結部２は、長手方向中間部に、横脚杆部22よりも上位置で左右外方へ突出する前後一対の横柱部25ｄ，25ｄを有する（平均台が前後に並んだような形状の）被把持部25を備えている（図１と図４と図５参照）。
被把持部25は、腕金等の電力設備に設置する際に、鋏状挟持機構を有する遠隔棒（やっとこ形状の長尺作業具）等の高所設置作業具に、把持される部位である。
そして、中間連結杆部３は、被把持部25が遠隔棒等の高所設置作業具で把持された場合に、全体形状が円弧山型状に撓むのを防止できる。つまり、中間連結杆部３によって針１と針１の間が開くような変形を防止でき、形状や姿勢が安定して、遠隔棒等の高所設置作業具を用いた高所への設置が容易となる。 Further, the base end connecting portion 2 has a pair of front and rear horizontal pillar portions 25d and 25d protruding outward to the left and right at a position above the horizontal leg rod portion 22 at the intermediate portion in the longitudinal direction (balance beam is arranged in front and back). It is provided with a gripped portion 25 (see FIGS. 1, 4 and 5).
The gripped portion 25 is a portion to be gripped by a high-place installation work tool such as a remote rod (a long work tool having a scissors shape) having a scissors-shaped pinching mechanism when it is installed in an electric power facility such as an arm. ..
Then, when the gripped portion 25 is gripped by a high-place installation work tool such as a remote rod, the intermediate connecting rod portion 3 can prevent the entire shape from bending into an arc mountain shape. That is, the intermediate connecting rod portion 3 can prevent deformation such that the needle 1 and the needle 1 are opened, the shape and posture are stable, and the installation in a high place using a high place installation work tool such as a remote rod can be performed. It will be easy.

なお、本発明は、設計変更可能であって、隣り合う針１と針１の間に、中間連結杆部３を、複数本、ラダー状（梯子状）に設けても良い。
長手方向Ｎに沿って配設された複数本の中間連結杆部３を、側面視で、上下略同位置（一直線上）に配設するも良い。針１及び基端連結部（ベース部）２の材質は、絶縁材料であり、例えば、ポリプロピレンが望ましい。また、図例においては、複数本の針１の高さ寸法Ｈは、全て同じであるが、各針１の高さ寸法Ｈを相違させるも良い。 In the present invention, the design can be changed, and a plurality of intermediate connecting rods 3 may be provided between the adjacent needles 1 in a ladder shape (ladder shape).
A plurality of intermediate connecting rods 3 arranged along the longitudinal direction N may be arranged at substantially the same position (on a straight line) in the vertical direction in a side view. The material of the needle 1 and the base end connecting portion (base portion) 2 is an insulating material, and for example, polypropylene is desirable. Further, in the illustrated example, the height dimensions H of the plurality of needles 1 are all the same, but the height dimensions H of each needle 1 may be different.

以上のように、本発明の鳥類営巣防止具は、上方突出状の複数本の針１と、該複数本の針１の基端部を連結する細長状の基端連結部２と、を絶縁性樹脂で一体状に成形した鳥類営巣防止具であって、上記複数本の針１が、上記基端連結部２の長手方向Ｎに沿って1列
のみ列設されているので、カラス等の鳥類が巣作りする際に、小枝等の棒状巣材を上方から落下（投下）させても、針１に巣材が引っ掛かりにくく、確実に営巣を防止できる。つまり、針１によって駐鳥を防止しつつ、営巣も確実に防止できる。鳥類が駐鳥する虞れのある駐鳥スペースを無くして、確実に駐鳥を防止できる。また、針列を複数列設けた場合と比べて、針１が積雪の大型化（成長）を助けることがない。つまり、寒冷地（豪雪地帯）の駐鳥営巣防止に最適である。 As described above, the bird nesting prevention device of the present invention insulates a plurality of upwardly projecting needles 1 and an elongated base end connecting portion 2 connecting the proximal ends of the plurality of needles 1. It is a bird nesting prevention device integrally molded with a sex resin, and since the plurality of needles 1 are arranged in only one row along the longitudinal direction N of the proximal end connecting portion 2, a crow or the like can be used. Even if a rod-shaped nest material such as a twig is dropped (dropped) from above when a bird nests, the nest material is less likely to be caught by the needle 1 and nesting can be reliably prevented. That is, the needle 1 can prevent bird nesting while reliably preventing nesting. Birds can be reliably prevented from being parked by eliminating the bird parking space where birds may be parked. Further, as compared with the case where a plurality of needle rows are provided, the needle 1 does not help the increase in size (growth) of the snow cover. In other words, it is most suitable for preventing bird nesting in cold regions (heavy snowfall areas).

また、隣り合う上記針１，１の上下中間部を相互に連結する中間連結杆部３を有するので、落下してくる巣材が、設置面（駐鳥営巣防止面）Ｇや基端連結部２に到達する前に、中間連結杆部３に接触するため、巣材が左右外方へ滑落したり、巣材がはじかれて、設置面Ｇ上や基端連結部２上に堆積するのを防止できる。また、雪の塊が大きくなることを防止できる（積雪の成長を防止できる）。 Further, since the intermediate connecting rod portion 3 for connecting the upper and lower intermediate portions of the adjacent needles 1 and 1 to each other is provided, the falling nest material can be the installation surface (bird nesting prevention surface) G or the base end connecting portion. Before reaching 2, the nest material slides outward to the left and right because it comes into contact with the intermediate connecting rod portion 3, or the nest material is repelled and deposited on the installation surface G or the base end connecting portion 2. Can be prevented. In addition, it is possible to prevent the snow mass from becoming large (it is possible to prevent the growth of snow).

また、複数本の上記中間連結杆部３は、側面視で千鳥状に配設されているので、鳥類の一方の脚が、一方の中間連結杆部３Ａを掴み、鳥類の他方の脚が、他方の中間連結杆部３Ｂを掴もうとしても、高さ（上下位置）が異なり、姿勢が不安定になるため、鳥類が本能的に嫌がって、中間連結杆部３への駐鳥を防止できる。 Further, since the plurality of the intermediate connecting rods 3 are arranged in a staggered manner in a lateral view, one leg of the bird grips one of the intermediate connecting rods 3A, and the other leg of the bird holds the other. Even if you try to grab the other intermediate connecting rod 3B, the height (upper and lower position) will be different and the posture will be unstable, so birds will instinctively dislike it and you can prevent birds from being parked in the intermediate connecting rod 3. ..

また、上記中間連結杆部３は、横断面円形状であって、直径寸法ｄを２ｍｍ以上４ｍｍ以下に設定したので、中間連結杆部３を鳥類が掴みにくくなって駐鳥を防止できると共に、十分な強度が得られて、製品搬送中や施工中等に変形や破損するのを防止できる。また、樹脂金型の製造も容易である。 Further, since the intermediate connecting rod portion 3 has a circular cross-sectional shape and the diameter dimension d is set to 2 mm or more and 4 mm or less, it becomes difficult for birds to grasp the intermediate connecting rod portion 3 and birds can be prevented from being parked. Sufficient strength can be obtained to prevent deformation or damage during product transportation or construction. In addition, it is easy to manufacture a resin mold.

また、上記基端連結部２の設置裏面２ｂから上記針１の先端11までの高さ寸法Ｈを、１７０ｍｍ以上２３０ｍｍ以下に設定し、上記針１の先端11から上記中間連結杆部３までの上下寸法ｈを、８０ｍｍ以上１５０ｍｍ以下に設定したので、針１による鳥類への威嚇（忌避）効果を保持しながらも、中間連結杆部３への駐鳥を防止できる。また、針１が長過ぎず、製造や取扱いが容易で使い勝手が良い。中間連結杆部３を掴もうとする鳥類の腹部に針１の先端11が接触して駐鳥防止効果を向上できる。また、巣材が、設置面Ｇと中間連結杆部３とに引っ掛かるのを防止できる。 Further, the height dimension H from the installation back surface 2b of the base end connecting portion 2 to the tip 11 of the needle 1 is set to 170 mm or more and 230 mm or less, and from the tip 11 of the needle 1 to the intermediate connecting rod portion 3. Since the vertical dimension h is set to 80 mm or more and 150 mm or less, it is possible to prevent birds from being parked in the intermediate connecting rod portion 3 while maintaining the threatening (repelling) effect of the needle 1 on birds. In addition, the needle 1 is not too long, is easy to manufacture and handle, and is easy to use. The tip 11 of the needle 1 comes into contact with the abdomen of a bird trying to grab the intermediate connecting rod portion 3, and the effect of preventing bird parking can be improved. Further, it is possible to prevent the nest material from being caught between the installation surface G and the intermediate connecting rod portion 3.
