A connecting rod 6 capable of twisting deformation. In the present invention, the direction along the axial center of the cylindrical wire insertion portion 4 is referred to as the axial direction L, and for the bird flying prevention device, it is connected to the wire insertion portion 4 (cover 3). Assuming the attached state, it is referred to as the axial direction L. The plurality of clip portions 1 are arranged with a predetermined pitch, and between the adjacent clip portions 1, 1, inclined obstacle protrusions 2, 2 are arranged as described later.

図１〜図６に示したように、各クリップ部１は、（電線保護カバー３への取付状態で、）電線挿通部４を左右両側から挟持すると共にカバー３の下辺突条部５が通される切れ目11を下部に有する正面視円環状挟持部10を具備する。挟持部10は、側方に開口する窓部17を有するフレーム材18を正面視円環状に弯曲形成したものである。具体的には、各挟持部10は、窓部17を上側窓部17Ａと下側窓部17Ｂとに分割する軸心方向Ｌに平行な補強用横杆部15，15を、上下中間位置に両側に有する。言い換えると、挟持部10は、切れ目11を下部に有する閉ループ形状である。そして、フレーム材18のうち横杆部15よりも下側に配設される下側枠部18Ｂは、上側に配設される上側枠部18Ａよりも狭い間隔を有するように形成され、下側枠部18Ｂの軸心方向Ｌの幅寸法は、上側枠部18Ａが成す窓部17Ａの幅寸法と略同じ大きさに設定される（図４，図５参照）。   As shown in FIGS. 1 to 6, each clip portion 1 holds the wire insertion portion 4 from both the left and right sides (when attached to the wire protection cover 3) and allows the lower ridge portion 5 of the cover 3 to pass. A front-view annular holding part 10 having a cut 11 formed in the lower part is provided. The sandwiching portion 10 is formed by bending a frame material 18 having a window portion 17 that opens to the side into an annular shape when viewed from the front. Specifically, each sandwiching portion 10 has reinforcing horizontal flange portions 15 and 15 parallel to the axial direction L dividing the window portion 17 into an upper window portion 17A and a lower window portion 17B at the upper and lower intermediate positions. Have on both sides. In other words, the clamping part 10 has a closed loop shape having the cut 11 at the lower part. The lower frame portion 18B disposed below the horizontal flange portion 15 in the frame member 18 is formed to have a narrower interval than the upper frame portion 18A disposed on the upper side. The width dimension in the axial direction L of the frame portion 18B is set to be approximately the same as the width dimension of the window portion 17A formed by the upper frame portion 18A (see FIGS. 4 and 5).

また、各クリップ部１は、挟持部10の切れ目11を成す両下縁部12，12に、カバー３の電線挿通部４に上方から嵌込む際に誘導する一対の弯曲片部13，13を下方拡開状に有する。弯曲片部13は、外方側が半円弧形状を有する小片部材を、下面側が凸状となるように緩やかに弯曲形成したものであり、下側枠部18Ｂの下端に固着される。また、下縁部12，12間の切れ目11の間隔寸法Ｄ₁₁は、自由状態（カバー３に取付けられていない状態）において、カバー３の下辺突条部５の厚さ（横幅）よりも僅かに大きな間隔を有する。取付部７は、弯曲片部13以外が全て線条体から形成されており、軽量化が図られると共に、弾性変形し易くなりカバー３に嵌込み易い構造である。
そして、各弯曲片部13には１個の挿通用孔14が形成されており、取付部７がカバー３に取付けられた状態に於て、各クリップ部１の一対の弯曲片部13，13の孔14，14に紐状の離脱防止部材16を通して、両端部が留められる（図３参照）。これによれば、離脱防止部材16がカバー３の下辺突条部５を下方から包囲しており、装置に外力が掛かりクリップ部１がカバー３の電線挿通部４から脱しかけても、離脱防止部材16が、カバー３の下辺突条部５の下端に引っ掛かるため離脱が防止される。なお、離脱防止部材16の一端が一方の弯曲片部13に一体成形され、防止部材16の他端を他方の弯曲片部13の孔14に通して留めるように形成するのも良い。
また、連結杆６は、正面視において略平坦な底面と弯曲凸状の上面部とを有する略蒲鉾型の細線材から成る。 In addition, each clip portion 1 has a pair of bent piece portions 13 and 13 that are guided to the lower edge portions 12 and 12 that form the cut line 11 of the sandwiching portion 10 when fitted into the wire insertion portion 4 of the cover 3 from above. It has a downward expanding shape. The bent piece portion 13 is formed by gently bending a small piece member having a semicircular arc shape on the outer side so that the lower surface side is convex, and is fixed to the lower end of the lower frame portion 18B. Further, the distance D ₁₁ of the cut 11 between the lower edge portions 12 and 12 is slightly smaller than the thickness (lateral width) of the lower ridge portion 5 of the cover 3 in a free state (in a state where it is not attached to the cover 3). Have a large spacing. The mounting portion 7 is formed of a linear body except for the bent piece portion 13 and is light in weight, and is easily elastically deformed and easily fitted into the cover 3.
Each bent piece 13 is formed with one insertion hole 14, and the pair of bent pieces 13, 13 of each clip portion 1 in a state where the attaching portion 7 is attached to the cover 3. Both ends are fastened to the holes 14 and 14 through the string-like detachment preventing member 16 (see FIG. 3). According to this, the detachment preventing member 16 surrounds the lower ridge 5 of the cover 3 from below, and even when an external force is applied to the apparatus and the clip portion 1 is detached from the wire insertion portion 4 of the cover 3, the detachment prevention is prevented. Since the member 16 is hooked on the lower end of the lower ridge portion 5 of the cover 3, detachment is prevented. Note that one end of the separation preventing member 16 may be formed integrally with the one bent piece 13 and the other end of the preventing member 16 may be fastened through the hole 14 of the other bent piece 13.
The connecting rod 6 is made of a substantially bowl-shaped thin wire material having a substantially flat bottom surface and a curved convex upper surface portion when viewed from the front.

次に、障害突部２について説明する。
図１〜図６に於て、障害突部２は、各クリップ部１の前後中間位置において、連結杆６上に起立状に立設された上向き障害突部２Ａと、隣り合うクリップ部１，１間に於て正面視上方拡開状に突設された傾斜障害突部２Ｂと、を有する。
先ず、上向き障害突部２Ａは、軸心方向Ｌにおける各クリップ部１の中央位置において連結杆６に上方へ真っ直ぐ突設されている。また、上向き障害突部２Ａは、連結杆６の下部に開口する細長状の収納空洞部21が形成されており、他の装置の障害突部２Ａが差込まれて、鳥類飛来防止装置を二つ以上積み重ね可能である（図６，図10参照）。 Next, the obstacle protrusion 2 will be described.
In FIG. 1 to FIG. 6, the obstacle protrusion 2 includes an upward obstacle protrusion 2 </ b> A standing upright on the connecting rod 6 at the front and rear intermediate positions of each clip portion 1, and the adjacent clip portions 1, 2. 1 and an inclined obstacle protrusion 2B that protrudes upward in a front view.
First, the upward obstacle protrusion 2 </ b> A protrudes straight upward from the connecting rod 6 at the center position of each clip portion 1 in the axial direction L. Further, the upward obstacle protrusion 2A is formed with an elongated storage cavity 21 that opens at the bottom of the connecting rod 6, and the obstacle protrusion 2A of another device is inserted, so that the bird flying prevention device 2 Two or more can be stacked (see FIGS. 6 and 10).

次に、傾斜障害突部２Ｂについて説明すると、隣り合うクリップ部１，１の間には、左右一対の傾斜障害突部２Ｂ，２Ｂが正面視上方拡開状に設けられる。この一対の傾斜障害突部２Ｂ，２Ｂは、下部に形成された小円弧状の基部22，22をもって、連結杆６に一体に設けられている。このように、上向き障害突部２Ａと、左右一対の傾斜障害突部２Ｂ，２Ｂとは、軸心方向Ｌにずれた位置にて突設されており、軸心方向Ｌから見て放射状に配設される（図３，図６参照）。
また、隣り合う障害突部２Ｂの基部22とクリップ部１の間には、連結杆６を切断可能とする隙間Ｓが形成されている（図２，図４，図５参照）。
上向き障害突部２Ａと傾斜障害突部２Ｂは共に細長四角錐状に形成され、尖り状の頂部を有するが、頂部を尖り状ではなく、弯曲上面を有する丸形状としてもよい。 Next, the inclination obstacle protrusion 2B will be described. Between the adjacent clip parts 1 and 1, a pair of left and right inclination obstacle protrusions 2B and 2B are provided so as to expand upward in a front view. The pair of inclined obstacle protrusions 2B and 2B are integrally provided on the connecting rod 6 with small arc-shaped base portions 22 and 22 formed in the lower portion. As described above, the upward obstacle protrusion 2A and the pair of left and right inclined obstacle protrusions 2B and 2B are protruded at positions shifted in the axial direction L, and are arranged radially when viewed from the axial direction L. (See FIGS. 3 and 6).
Further, a gap S is formed between the base portion 22 of the adjacent obstacle protrusion 2B and the clip portion 1 so that the connecting rod 6 can be cut (see FIGS. 2, 4 and 5).
Both the upward obstacle protrusion 2A and the inclination obstacle protrusion 2B are formed in an elongated quadrangular pyramid shape and have a pointed apex, but the apex may be a round shape having a curved upper surface instead of a pointed shape.

なお、カバー３に取付状態で、各傾斜障害突部２Ｂが、鉛直方向に対して成す傾斜角度θ₂ は20°〜40°であり、略30°であるのが望ましい。θ₂ が20°未満であると、カバー３が捩じれた状態（カバー３の下辺突条部５が側方下傾となる状態）になる場合、その捩じれ具合が大きい場合に傾斜障害突部２Ｂが上方向を向かず、鳥類飛来防止機能が低くなる。また、θ₂ が40°超過であると、カバー３の捩じれ具合が小さい場合（例えば、カバー３が20°捩じれて保持される場合）に上向き障害突部２Ａ・傾斜障害突部２Ｂが共に上方向を向かず、鳥類飛来防止機能が低くなる。 In addition, the inclination angle θ ₂ formed with respect to the vertical direction by each inclination obstacle protrusion 2B in the state of being attached to the cover 3 is 20 ° to 40 °, and is preferably about 30 °. If θ ₂ is less than 20 °, when the cover 3 is twisted (the lower ridge 5 of the cover 3 is tilted downward in the side), the tilt obstacle protrusion 2B when the twist is large. However, the bird's flight prevention function is lowered. If θ ₂ exceeds 40 °, both the upward obstacle protrusion 2A and the inclined obstacle protrusion 2B are upward when the twist degree of the cover 3 is small (for example, when the cover 3 is twisted and held by 20 °). The bird's flying prevention function becomes low without turning in the direction.

そして、複数の障害突部２…と取付部７はプラスチック等の弾性変形可能な絶縁材料から成り、一体に射出成形されている。即ち、クリップ部１は挟持部10と弯曲片部13，13が一体形成されて成り、複数のクリップ部１…が連結杆６と一体形成されて取付部７を成す。   The plurality of obstacle protrusions 2 and the mounting portion 7 are made of an elastically deformable insulating material such as plastic and are integrally injection-molded. That is, the clip portion 1 is formed by integrally forming the sandwiching portion 10 and the bent piece portions 13, 13, and the plurality of clip portions 1 are integrally formed with the connecting rod 6 to form the attachment portion 7.

次に、本発明の鳥類飛来防止装置を電線保護カバー３に取付ける手順について説明する。図７に於て、取付部７のクリップ部１の弯曲片部13，13の下面を、電線に取付済みの電線保護カバー３の電線挿通部４に上方から押し付けると、弯曲片部13，13が電線挿通部４の上面に沿ってスライドし、挟持部10が左右方向外方へ弾性変形により拡がりつつ誘導される。そして、クリップ部１の挟持部10を電線保護カバー３に完全に外嵌して、図１〜図３に示したように、弾性力で復元してカバー３を挟持すればセット完了である。挟持部10は上述のように窓部17を有する線条体から成り、非常に柔軟に弾性変形するので、上方から押し込むだけで容易にセットできて、少人数でも迅速に取付可能である。取付けた状態において、カバー３の下辺突条部５が、挟持部10の下縁部12，12間の切れ目11を通って下方へ突出するため、下辺突条部５の上部が下縁部12，12によって両側から受けられており、装置は、風等の外力を受けてもカバー３に対して揺動（回転）しない。   Next, a procedure for attaching the bird flying prevention apparatus of the present invention to the wire protection cover 3 will be described. In FIG. 7, when the lower surfaces of the bent piece portions 13 and 13 of the clip portion 1 of the attachment portion 7 are pressed from above onto the electric wire insertion portion 4 of the electric wire protection cover 3 attached to the electric wire, the bent piece portions 13 and 13 are pressed. Slides along the upper surface of the wire insertion part 4, and the clamping part 10 is guided while expanding outwardly in the left-right direction by elastic deformation. And if the clamping part 10 of the clip part 1 is completely externally fitted to the electric wire protection cover 3, and it restore | restores with an elastic force and clamps the cover 3 as shown in FIGS. 1-3, it is set completion. As described above, the sandwiching portion 10 is composed of a linear body having the window portion 17 and is elastically deformed very flexibly. Therefore, the sandwiching portion 10 can be easily set simply by pushing from above, and can be quickly attached even by a small number of people. In the mounted state, the lower ridge portion 5 of the cover 3 protrudes downward through the cut 11 between the lower edge portions 12 and 12 of the clamping portion 10, so that the upper portion of the lower ridge portion 5 is the lower edge portion 12. , 12, and the device does not swing (rotate) with respect to the cover 3 even when an external force such as wind is received.

そして、各クリップ部１において、左右弯曲片部13，13の挿通用孔14，14に紐状の離脱防止部材16を通して、カバー３の下辺突条部５を下方から包囲するようにして、両端部を留める（図３参照）。仮に、装置にカバー３から離脱するような外力が掛かりクリップ部１がカバー３の電線挿通部４から脱しかけても、離脱防止部材16が、カバー３の下辺突条部５の下端に引っ掛かるため離脱が防止される。なお、電線に取付ける前の電線保護カバー３に対しても本発明の装置を着脱するのもよく、電線に取付後のカバー３に着脱する場合と異なり、横に寝かせた状態で着脱可能である。   And in each clip part 1, the string-like detachment preventing member 16 is passed through the insertion holes 14 and 14 of the left and right curved piece parts 13 and 13 so as to surround the lower ridge part 5 of the cover 3 from below. The part is fastened (see FIG. 3). Even if an external force is applied to the apparatus so as to be detached from the cover 3 and the clip portion 1 is detached from the wire insertion portion 4 of the cover 3, the separation preventing member 16 is caught on the lower end of the lower ridge portion 5 of the cover 3. Withdrawal is prevented. Note that the apparatus of the present invention may be attached to and detached from the wire protection cover 3 before being attached to the wire, and can be attached and detached in a state of being laid down, unlike the case of being attached to and detached from the cover 3 after being attached to the wire. .

また、連結杆６を、相互に隣り合うクリップ部１と傾斜障害突部２Ｂの間の隙間Ｓにより、切断工具を用いて切断することで、容易に分断できるので、現場にて、容易に所望の長さに加工でき、加工性と作業性が上がる。また、各クリップ部１は単独でもカバー３を挟持可能であり、連結杆６をどの部位で分断しても、クリップ部１がカバー３を確実に挟持する。また、クリップ部１と傾斜障害突部２Ｂとが交互に連結杆６に取り付けられていることから、連結杆６をどのような所望の位置で分断しても、装置は障害突部２Ｂを含むようになる。   Further, the connecting rod 6 can be easily divided by cutting with a cutting tool by the gap S between the adjacent clip portion 1 and the inclined obstacle protrusion 2B. Can be machined to a long length, improving workability and workability. In addition, each clip part 1 can hold the cover 3 alone, and the clip part 1 securely holds the cover 3 regardless of where the connecting rod 6 is divided. In addition, since the clip portions 1 and the inclined obstacle protrusions 2B are alternately attached to the connecting rod 6, the apparatus includes the obstacle protrusion 2B regardless of the desired position of the connecting rod 6. It becomes like this.

また、電線保護カバー３内に複数本の電線を通した場合カバー３の電線挿通部４の外径が大きくなるが、各クリップ部１は、電線挿通部４の形状に合わせて変形して取付可能である。また、取付けられた状態で、各クリップ部１は弾発付勢力（復元力）によってカバー３の電線挿通部４を締め付けるため、脱落が防止される。   Further, when a plurality of electric wires are passed through the electric wire protection cover 3, the outer diameter of the electric wire insertion portion 4 of the cover 3 is increased, but each clip portion 1 is deformed according to the shape of the electric wire insertion portion 4 and attached. Is possible. Moreover, since each clip part 1 tightens the electric wire insertion part 4 of the cover 3 by the elastic biasing force (restoring force) in the attached state, drop-off is prevented.

そして、図９（Ａ）に示したように、電線（及び、保護カバー３）が捩じれる（カバー３の下辺突条部５が側方下傾となる）と、図９（Ｂ）のように、連結杆６が捩じれ変形して、クリップ部１…はカバー３に外嵌した状態で捩じれに追従する。クリップ部１…は１本の捩じれ変形自在な背骨状の連結杆６によって連結されており、連結杆６は、カバー３の捩じれ具合に柔軟に対応して捩じれるので、クリップ部１…がカバー３を挟持する状態が保たれ、離脱するのが防止される。
また、捩じれたクリップ部１…は、その傾斜障害突部２Ｂ…が上方向を向くので、鳥類飛来防止機能は保たれる。 Then, as shown in FIG. 9A, when the electric wire (and the protective cover 3) is twisted (the lower ridge 5 of the cover 3 is tilted sideways), as shown in FIG. 9B. In addition, the connecting rod 6 is twisted and deformed, and the clip portions 1... Follow the twist while being fitted on the cover 3. The clip portion 1 is connected by a single twistable deformable spine-shaped connecting rod 6, and the connecting rod 6 is twisted in a flexible manner corresponding to the twisted state of the cover 3, so that the clip portion 1. 3 is maintained and is prevented from being detached.
Also, the twisted clip portion 1 has the tilt obstacle projection 2B facing upward, so that the bird flying prevention function is maintained.

また、本装置を図５に於て平面視したとき、弯曲片部13が、下側枠部18Ｂが成す下側窓部17Ｂ内に納まり（上下方向で重なる部分が無く）、かつ、下側枠部18Ｂが、上側枠部18Ａが成す上側窓部17Ａ内に納まり、かつ、連結杆６が、挟持部10の下縁部12，12が成す切れ目11内に納まる。かつ、平面視に於て、傾斜障害突部２Ｂは、クリップ部１・連結杆６に上下方向で重ならず、かつ、上向き障害突部２Ａは、連結杆６上に突設されている。従って、本装置は、上型と下型とを上下方向に合わせて射出成形を行うことが可能である。そして、射出による一体成形によって製造できることから大量生産が容易である。また、クリップ部１の挟持部10を形成するための中子（コア）が不要であり、金型の製造コストが抑えられる。   Further, when the apparatus is viewed in plan in FIG. 5, the bent piece portion 13 is accommodated in the lower window portion 17B formed by the lower frame portion 18B (there is no overlapping portion in the vertical direction), and the lower side The frame portion 18B is accommodated in the upper window portion 17A formed by the upper frame portion 18A, and the connecting rod 6 is accommodated in the cut 11 formed by the lower edges 12 and 12 of the sandwiching portion 10. In addition, in plan view, the inclined obstacle protrusion 2B does not overlap the clip part 1 and the connecting rod 6 in the vertical direction, and the upward obstacle protruding portion 2A protrudes on the connecting rod 6. Therefore, this apparatus can perform injection molding by aligning the upper mold and the lower mold in the vertical direction. And since it can manufacture by integral molding by injection, mass production is easy. Moreover, a core (core) for forming the clamping part 10 of the clip part 1 is unnecessary, and the manufacturing cost of the mold can be suppressed.

次に、二つ以上の本装置を積み重ねて梱包することについて説明する。
図６，図10に於て、上向き障害突部２Ａは、連結杆６の下部に開口する細長状の収納空洞部21が形成されている。従って、一（上側）の装置を他（下側）の装置に上方から重ねると、上側装置の上向き障害突部２Ａ…の収納空洞部21…に、下側の装置の上向き障害突部２Ａ…が差し込まれる（図10参照）。さらに、下側装置の連結杆６が、上側装置の切れ目11を通り、かつ、上側装置の弯曲片部13…及び下側枠部18Ｂ…が、下側装置の上側窓部17Ａ…を通って納まる状態になる。さらに、上側装置と下側装置の傾斜障害突部２Ｂ…が非接触状で上下に重なる。このように、装置をコンパクトに積み重ねて梱包できる。そして、上向き障害突部２Ａが収納されることで保護されて運搬時等の破損が防がれる。 Next, stacking and packing two or more present apparatuses will be described.
6 and 10, the upward obstacle protrusion 2 </ b> A is formed with an elongated storage cavity 21 that opens at the bottom of the connecting rod 6. Accordingly, when one (upper) device is overlapped with the other (lower) device from above, the upper obstacle protrusion 2A of the lower device is placed in the storage cavity 21 of the upper obstacle protrusion 2A of the upper device. Is inserted (see FIG. 10). Further, the connecting rod 6 of the lower device passes through the cut 11 of the upper device, and the bent piece portion 13 and the lower frame portion 18B of the upper device pass through the upper window portion 17A of the lower device. It will be in a state that fits. Further, the slope obstacle protrusions 2B of the upper device and the lower device overlap with each other in a noncontact manner. In this way, the devices can be stacked and packed compactly. And it is protected by storing the upward obstacle protrusion 2A, and damage during transportation is prevented.

また、図７，図８に示したように、傾斜障害突部２Ｂを横断面Ｈ型として、樹脂の使用量を減少し、軽量化を図りつつ、強度を確保することも、好ましい（図１〜図６のいずれにも応用可能）。
また、図示省略するが、本装置は設計変更自由であり、上述の上向き障害突部２Ａ、傾斜障害突部２Ｂに加えて、鉛直方向に対して成す傾斜角度が傾斜障害突部２Ｂよりも大きな障害突部２…を本装置に設けるのもよい。例えば、各クリップ部１の一対の横杆部15，15に、傾斜障害突部２Ｂの傾斜角度θ₂ よりも大きな傾斜角度をもって大傾斜障害突部２，２を取付けて、正面視上方拡開状に一体に突設する。このとき、上向き障害突部２Ａ、傾斜障害突部２Ｂ，２Ｂ、及び、大傾斜障害突部２，２が、軸心方向Ｌから見て、放射状に（紅葉の葉のように）配設され、カバー３が大きく捩じれた場合でも、大傾斜障害突部２が上方向に向いて鳥類飛来防止機能が発揮される。しかも、この大傾斜障害突部２は、クリップ部１の横杆部15から突設されることで、上下方向において他のどの部分とも重ならないので、上型・下型を上下方向に重ねて射出成形可能となるので有効である。 Further, as shown in FIGS. 7 and 8, it is also preferable to secure the strength while reducing the amount of resin used and reducing the amount of resin used by making the inclined obstacle protrusion 2B an H-shaped cross section (FIG. 1). Applicable to any of FIG. 6).
Although not shown, the design of the apparatus is freely changeable, and in addition to the upward obstacle protrusion 2A and the inclination obstacle protrusion 2B, the inclination angle formed with respect to the vertical direction is larger than that of the inclination obstacle protrusion 2B. Obstacle protrusions 2 may be provided in the apparatus. For example, the large inclined obstacle protrusions 2 and 2 are attached to the pair of horizontal flange parts 15 and 15 of each clip part 1 with an inclination angle larger than the inclination angle θ ₂ of the inclination obstacle protrusion 2B, and are expanded upward in front view. Protrusively integrated into the shape. At this time, the upward obstacle protrusions 2A, the inclination obstacle protrusions 2B and 2B, and the large inclination obstacle protrusions 2 and 2 are arranged radially (as in the leaves of autumn leaves) as viewed from the axial direction L. Even when the cover 3 is largely twisted, the large inclination obstacle protrusion 2 is directed upward, and the bird flying prevention function is exhibited. In addition, since the large inclined obstacle protrusion 2 is projected from the horizontal flange portion 15 of the clip portion 1 and does not overlap with any other portion in the vertical direction, the upper mold and the lower mold are stacked in the vertical direction. This is effective because injection molding is possible.

また、本装置は、連結杆６に例えば12個のクリップ部１…が連結状となって形成される。この場合、12個全てのクリップ部１…カバー３に嵌めるのは容易ではないことから、本装置を次のように設計変更することもできる。即ち、図１に於て、クリップ部１…のうち、例えば、１つ置きや２つ置きのクリップ部１を、下側枠部18Ｂと弯曲片部13，13が省略され上側枠部18Ａのみから成るように形成する。これによれば、装置をカバー３に嵌込む際に弾性変形で拡げて外嵌させるクリップ部１の数量が（全てのクリップ部１…が挟持部10を有する場合に比べて）少ないので、取り付けがスムーズとなる。
また、図１に示したように、１ユニットの本装置を、連結杆６の一端には傾斜障害突部２Ｂを突設させ、かつ、連結杆６の他端には障害突部２Ｂを設けないように形成することで、２つ以上の本装置を連続してカバー３に取付けた場合に、上向き障害突部２Ａと傾斜障害突部２Ｂとが所定ピッチで連続して配設されるようになる。 Further, in the present apparatus, for example, twelve clip portions 1... In this case, since it is not easy to fit all the 12 clip portions 1 to the cover 3, the design of this apparatus can be changed as follows. That is, in FIG. 1, of the clip portions 1..., For example, every other clip portion or every other clip portion 1, the lower frame portion 18B and the bent piece portions 13 and 13 are omitted, and only the upper frame portion 18A. It is formed to consist of According to this, since the number of clip parts 1 to be expanded and externally fitted by elastic deformation when the device is fitted into the cover 3 is small (compared to the case where all the clip parts 1. Becomes smooth.
In addition, as shown in FIG. 1, one unit of this apparatus is provided with an inclined obstruction protrusion 2 </ b> B at one end of the connecting rod 6 and an obstruction protrusion 2 </ b> B at the other end of the connecting rod 6. When the two or more devices are continuously attached to the cover 3, the upward obstacle protrusion 2A and the inclined obstacle protrusion 2B are continuously arranged at a predetermined pitch. become.

以上のように、本発明に係る電線保護カバー用の鳥類飛来防止装置は、電線保護カバー３に着脱自在に取着される取付部７と、取付部７から上方へ突設された複数の障害突部２とを、備え、取付部７は、カバー３を左右両側から挟持する弾性変形可能な複数のクリップ部１と、複数のクリップ部１の上部１ａを貫通して連結する１本の捩じり変形可能な連結杆６と、を具備するので、電線に取付済みの電線保護カバー３に上から被せるだけで装置を取付けることができ、少人数でも容易に取付可能となる。また、複数のクリップ部１…の夫々が、カバー３を左右両側から弾性力によって挟持するので、取付後に、取付部７が不意にカバー３から外れるのを確実に防止できる。
また、連結杆６が捩じれ変形可能なので、電線（カバー３）が捩じれても、クリップ部１…がカバー３に外嵌した状態で捩じれに柔軟に対応して追従することができ、クリップ部１…がカバー３から離脱するのを防止できる。 As described above, the bird flying prevention apparatus for an electric wire protection cover according to the present invention includes an attachment portion 7 that is detachably attached to the electric wire protection cover 3 and a plurality of obstacles protruding upward from the attachment portion 7. The mounting portion 7 includes a plurality of elastically deformable clip portions 1 that sandwich the cover 3 from the left and right sides, and one screw that penetrates and connects the upper portions 1 a of the plurality of clip portions 1. Since the connecting rod 6 that can be twisted is provided, the device can be attached simply by covering the wire protective cover 3 already attached to the wire from above, and even a small number of people can easily attach it. Further, since each of the plurality of clip portions 1 holds the cover 3 by elastic force from both the left and right sides, it is possible to reliably prevent the attachment portion 7 from being unexpectedly detached from the cover 3 after attachment.
Further, since the connecting rod 6 can be twisted and deformed, even when the electric wire (cover 3) is twisted, the clip portion 1 can flexibly follow the twist while being externally fitted to the cover 3, and the clip portion 1 Can be prevented from being detached from the cover 3.

また、クリップ部１は、カバー３に取付状態で、カバー３の円筒状電線挿通部４を左右両側から挟持すると共にカバー３の下辺突条部５が通される切れ目11を下部に有する正面視円環状（閉ループ形状）挟持部10を具備するので、両側からカバー３を確実に挟持して不意に外れることがない。しかも、切れ目11を成す挟持部10の下縁部12，12がカバー３の下辺突条部５の上部を両側から受けるので、外力等を受けても装置がカバー３に対して回転することがなく、障害突部２…を上向きに保持できて、鳥類の飛来を確実に防止できる。   Further, the clip portion 1 is attached to the cover 3, holds the cylindrical wire insertion portion 4 of the cover 3 from both the left and right sides, and has a cut 11 at the lower portion through which the lower ridge portion 5 of the cover 3 passes. Since the annular (closed loop shape) clamping part 10 is provided, the cover 3 is securely clamped from both sides and does not come off unexpectedly. In addition, since the lower edge portions 12 and 12 of the sandwiching portion 10 forming the cut 11 receive the upper portion of the lower ridge portion 5 of the cover 3 from both sides, the device can rotate with respect to the cover 3 even when receiving an external force or the like. The obstacle protrusions 2 can be held upward, and birds can be reliably prevented from flying.

また、挟持部10は、側方に開口する窓部17を有するフレーム材18が弯曲形成されたものなので、装置全体の軽量化を図ることができる。しかも、挟持部10が弾性変形し易いので、取付の際にスムーズにカバー３に嵌める作業を行うことができる。また、射出成形により容易に大量生産をすることができ、しかも、少ない材料で製造できるので、コストも低減できる。   Further, since the sandwiching portion 10 is formed by bending a frame material 18 having a window portion 17 that opens to the side, the weight of the entire apparatus can be reduced. In addition, since the clamping portion 10 is easily elastically deformed, it is possible to perform an operation of fitting the cover 3 smoothly in the mounting. In addition, mass production can be easily performed by injection molding, and the cost can be reduced because it can be manufactured with a small amount of material.

また、クリップ部１は、挟持部10の切れ目11を成す両下縁部12，12に、カバー３の電線挿通部４に上方から嵌込む際に誘導する一対の弯曲片部13，13を下方拡開状に有するので、弯曲片部13，13をカバー３の電線挿通部４に上方から押し付ければ、その下面が電線挿通部４の上面をスライドし、挟持部10がスムーズに側方へ拡がる。よって、カバー３への取付作業が非常に楽になるので、少人数でも容易に取付作業を行うことができ、現場での作業性を向上させることができる。   Further, the clip portion 1 has a pair of bent piece portions 13 and 13 that are guided when fitted into the wire insertion portion 4 of the cover 3 from above on the lower edge portions 12 and 12 that form the cut 11 of the holding portion 10. Since it has an expanded shape, if the bent pieces 13 and 13 are pressed against the wire insertion portion 4 of the cover 3 from above, the lower surface slides on the upper surface of the wire insertion portion 4, and the clamping portion 10 smoothly moves to the side. spread. Therefore, since the attachment work to the cover 3 becomes very easy, the attachment work can be easily performed even by a small number of people, and workability on the site can be improved.

また、弯曲片部13，13以外の部材が、全て線条体から形成されるので、装置全体の軽量化を図ることができると共に、弾性変形し易くなるので挟持部10が開き易くスムーズにカバー３に嵌める作業を行うことができる。また、連結杆６も線条体から形成されており、捩じれ変形し易いため、カバー３の捩じれ変形に非常に柔軟に対応して追従することができる。よって、クリップ部１…がカバー３から離脱するのが確実に防止される。   In addition, since all members other than the bent piece parts 13 and 13 are formed of a linear body, the entire apparatus can be reduced in weight, and can be easily elastically deformed so that the clamping part 10 can be easily opened and smoothly covered. 3 can be fitted. Further, since the connecting rod 6 is also formed of a linear body and easily twisted and deformed, it can follow the torsional deformation of the cover 3 in a very flexible manner. Therefore, the clip portions 1 are reliably prevented from being detached from the cover 3.

また、弯曲片部13は挿通用孔14が形成され、カバー３に取付状態で、各クリップ部１の一対の弯曲片部13，13の孔14，14に、紐状の離脱防止部材16を通して固定し、離脱防止部材16がカバー３の下辺突条部５を下方から包囲して離脱防止するように構成されているので、装置に、カバー３から離脱する方向へ外力が掛かって離脱しかけても、離脱防止部材16がカバー３の下辺突条部５の下端に引っ掛かるため離脱するのが防止される。   Further, the bent piece 13 is formed with an insertion hole 14, and is attached to the cover 3, and the string-like detachment preventing member 16 is passed through the holes 14, 14 of the pair of bent pieces 13, 13 of each clip portion 1. Since the detachment prevention member 16 surrounds the lower ridge 5 of the cover 3 from below to prevent detachment, the device is subjected to detachment by applying an external force in the direction of detachment from the cover 3. However, since the separation preventing member 16 is caught by the lower end of the lower ridge 5 of the cover 3, it is prevented from separating.

また、取付部７と複数の障害突部２が一体に射出成形されているので、製造が容易になり、大量生産を行うことができる。また、全体が強固な構造となり、カバー３に取付けた状態で外力を受けても破損しにくい。   Further, since the mounting portion 7 and the plurality of obstacle protrusions 2 are integrally formed by injection molding, manufacturing is facilitated and mass production can be performed. Moreover, even if the whole becomes a firm structure and receives external force in the state attached to the cover 3, it is hard to be damaged.

また、複数のクリップ部１は所定ピッチをもって配設され、かつ、隣り合うクリップ部１，１の間に、傾斜障害突部２Ｂ，２Ｂが正面視上方拡開状に配設され、かつ、隣り合う障害突部２Ｂとクリップ部１の間には隙間Ｓが形成されているので、連結杆６を、隙間Ｓの部位で切断工具を用いて切断できる。よって、現場にて、容易に所望の長さに加工でき、加工性と作業性が上がる。しかも、隣り合うクリップ部１，１間に傾斜障害突部２Ｂ，２Ｂが配設されているので、連結杆６をどの部位で分断しても、装置が傾斜障害突部２Ｂ，２Ｂを含む状態になり、カバー３に取付けて鳥類の飛来を確実に防止する機能を発揮できる。   Further, the plurality of clip portions 1 are arranged with a predetermined pitch, and between the adjacent clip portions 1, 1, the slant obstruction projections 2 </ b> B and 2 </ b> B are arranged so as to expand upward and are adjacent to each other. Since the gap S is formed between the matching obstacle protrusion 2B and the clip part 1, the connecting rod 6 can be cut at the site of the gap S using a cutting tool. Therefore, it can be easily processed to a desired length on site, and the workability and workability are improved. In addition, since the inclined obstacle protrusions 2B and 2B are disposed between the adjacent clip parts 1 and 1, the apparatus includes the inclined obstacle protrusions 2B and 2B regardless of where the connecting rod 6 is divided. Therefore, it can be attached to the cover 3 to exhibit the function of reliably preventing birds from flying.

また、軸心方向Ｌにおける各クリップ部１の中央位置に、上向きの障害突部２Ａが配設され、上向き障害突部２Ａと傾斜障害突部２Ｂとは、軸心方向Ｌから見て放射状に配設されているので、電線、及び、電線保護カバー３が捩じれた状態（カバー３の下辺突条部５が側方下傾となる状態）になってしまっても、通常（下辺突条部５が鉛直状態）では斜め上方を向いている障害突部２が上方を向くため、鳥類飛来防止機能を発揮できる。   Further, an upward obstacle protrusion 2A is disposed at the center position of each clip portion 1 in the axial direction L, and the upward obstacle protrusion 2A and the inclined obstacle protrusion 2B are radially viewed from the axial direction L. Even if the electric wire and the electric wire protection cover 3 are twisted (the lower ridge portion 5 of the cover 3 is inclined sideways), it is normal (the lower ridge portion). In the vertical state 5, the obstacle protrusion 2 that faces diagonally upward faces upward, so that the bird flying prevention function can be exhibited.
