Description

本発明は、営巣材撤去具に関し、特に、構造物の高所に形成された巣を撤去するのに用いられる営巣材撤去具に関する。   The present invention relates to a nesting material removing tool, and more particularly, to a nesting material removing tool used for removing a nest formed at a height of a structure.

送電線の鉄塔上部等の高所に営巣された鳥類の巣は、停電事故防止のために速やかに撤去される必要がある。巣の撤去作業においては、撤去する営巣材（木の枝、羽根、植物のつる、金属、土等）の飛散防止対策及び撤去後の営巣材を収納するための袋等が必要となる。   Birds nests nesting in high places such as the upper part of transmission towers need to be removed promptly to prevent power outages. In the nest removal work, it is necessary to take measures to prevent the nesting material (tree branches, feathers, plant vines, metal, soil, etc.) to be scattered and to store the nesting material after removal.

現状、営巣材の撤去には、営巣材の飛散防止としてビニールシート等を利用している。しかしながら、ビニールシート等は、巣を撤去する際に平坦に広げられた状態で利用されるため、特に構造物の高所等では、風の影響により波打つことがあった。このため、ビニールシート上に撤去された営巣材が、飛散又は落下することがあった。そこで、傘状に展開することで風の影響を排除し、営巣落下物を確実に取得する営巣落下物取得装置が知られている（例えば、特許文献１）。   At present, the removal of nesting materials uses vinyl sheets to prevent the nesting material from scattering. However, since a vinyl sheet or the like is used in a state where it is spread flat when the nest is removed, the vinyl sheet may wave due to the influence of the wind, particularly at a high place of the structure. For this reason, the nesting material removed on the vinyl sheet may be scattered or dropped. Therefore, there is known a nesting fallen object acquisition device that removes the influence of wind by deploying in an umbrella shape and reliably acquires nesting fallen objects (for example, Patent Document 1).

特許文献１に係る落下物取得装置は、高所への運搬が容易であり、巣の撤去時に営巣材を飛散又は落下させないという点で非常に有用である。さらに、巣の撤去時及び運搬時を通じて、営巣材を飛散又は落下させないことはより有用である。   The fallen object acquisition apparatus according to Patent Document 1 is very useful in that it can be easily transported to a high place and the nesting material is not scattered or dropped when the nest is removed. Furthermore, it is more useful not to scatter or drop the nesting material during removal and transportation of the nest.

本発明は、斯かる事情に鑑み、巣の撤去時及び運搬時を通じて、営巣材を飛散又は落下させない営巣材撤去具を提供することを課題とする。   In view of such circumstances, an object of the present invention is to provide a nesting material removal tool that does not scatter or drop the nesting material during removal and transportation of the nest.

本発明に係る営巣材撤去具は、構造物の高所に形成された巣を撤去するのに用いられる営巣材撤去具であって、長尺状に形成され、長手方向に伸縮可能な支柱部と、可撓性を有し、長尺状に形成され、一端側が支柱部の一端側に回動自在に支持されることで、他端側が支柱部の他端側に対して接離可能に設けられる複数の骨部と、それぞれ隣り合う骨部間を覆うように、複数の骨部に取り付けられるシート状の被覆部と、複数の骨部の他端側のそれぞれに取り付けられる紐状部と、支柱部の他端側に設けられ、紐状部を挿通する挿通孔を有し、挿通孔において紐状部を係止可能な係止部とを備える。   The nesting material removal tool according to the present invention is a nesting material removal tool used to remove a nest formed at a high position of a structure, and is formed in a long shape and can be extended and contracted in the longitudinal direction. And it is flexible, is formed in a long shape, and one end side is pivotally supported on one end side of the column part, so that the other end side can contact and separate from the other end side of the column part A plurality of bone portions, a sheet-like covering portion attached to the plurality of bone portions so as to cover between adjacent bone portions, and a string-like portion attached to each of the other ends of the plurality of bone portions; , Provided on the other end side of the column part, having an insertion hole for inserting the string-like part, and having a locking part capable of locking the string-like part in the insertion hole.

本発明に係る営巣材撤去具によれば、鉄塔等である構造物の高所に形成された巣を撤去するに際し、各骨部を支柱部側にまとめた状態で運搬される。具体的に、支柱部は、伸張された状態にされる。紐状部は、係止部の挿通孔内を支柱部の一端側から他端側へ挿通孔内を摺動する。これにより、骨部の一端側は、支持部の一端側に対して回動される。骨部の他端側は、支持部の他端側（係止部）に近接される。すなわち、骨部の長手方向は、支柱部の軸方向に沿う方向に向けられる。上記換言すれば、営巣材撤去具は、いわゆる傘を畳んだ状態で運搬される。   According to the nesting material removing tool according to the present invention, when removing the nest formed at the height of a structure such as a steel tower, the bone parts are transported in a state where they are gathered on the support column side. Specifically, the support column is in an extended state. The string-like portion slides in the insertion hole in the insertion hole of the locking portion from one end side to the other end side of the support column. Thereby, the one end side of a bone part is rotated with respect to the one end side of a support part. The other end side of the bone part is close to the other end side (locking part) of the support part. That is, the longitudinal direction of the bone part is directed in a direction along the axial direction of the support column part. In other words, the nesting material removing tool is transported in a state where a so-called umbrella is folded.

そして、営巣材撤去具は、構造物の高所における設置位置において、いわゆる傘を開いた状態で設置される。具体的に、支柱部は、伸張された状態のままにされる。紐状部は、係止部の挿通孔内を支柱部の他端側から一端側へ向けて摺動する。これにより、骨部の一端側は、支持部の一端側に対して回動される。骨部の他端側は、支柱部の他端側（係止部）から離間される。被覆部は、隣り合う骨部間を覆っているので、袋を開いた状態にされる。紐状部は、挿通孔において係止されることで、袋を開いた状態に被覆部を維持される。骨部は、可撓性を有することから、鉄塔等の構造物の形状に合わせて曲げ利用される。   And the nesting material removal tool is installed in a state where the so-called umbrella is opened at the installation position in the high place of the structure. Specifically, the support column is left in an extended state. The string-like portion slides in the insertion hole of the locking portion from the other end side to the one end side of the column portion. Thereby, the one end side of a bone part is rotated with respect to the one end side of a support part. The other end side of the bone part is separated from the other end side (locking part) of the support column part. Since the covering part covers between the adjacent bone parts, the bag is opened. The string-like portion is locked in the insertion hole, so that the covering portion is maintained in a state where the bag is opened. Since the bone part has flexibility, it is bent and used in accordance with the shape of a structure such as a steel tower.

これにより、鉄塔等の構造物の形状に合わせて被覆部を展開することができ、ひいては被覆部と鉄塔等の構造物との間の隙間を作らずに設置することができる。例えば、鉄塔の角部の内側に営巣材撤去具を設置する場合、鉄塔の構造物に沿って被覆部を展開できるので、鉄塔の構造物と被覆部との間から営巣材が落下することを防止できる。   Thereby, a coating | coated part can be expand | deployed according to the shape of structures, such as a steel tower, and by extension, it can install, without making the clearance gap between structures, such as a coating | coated part and a steel tower. For example, when installing a nesting material removal tool inside the corner of a steel tower, the covering part can be deployed along the structure of the steel tower, so that the nesting material falls between the structure of the steel tower and the covering part. Can be prevented.

被覆部上に撤去された営巣材が置かれた後、紐状部が、支柱部の一端側から他端側へ向けて挿通孔内を摺動する。骨部の一端側は、支柱部の一端側に対して回動される。骨部の他端側は、支柱部の他端側（係止部）に近接される。このとき、被覆部上には撤去された営巣材が置かれているので、骨部は、営巣材の存在により撓む。具体的に、骨部は、撤去された営巣材の形状に合わせ、支柱部の径外方向に向けて円弧状に撓む。支柱部は、骨部の撓みに合わせて長手方向に収縮される。被覆部は、隣り合う骨部間を覆うので、支柱部の一端側を底、支柱部の他端側を開口とする袋状に形成される。紐状部は、挿通孔において係止されることで、袋状にした状態に被覆部を維持する。また、係止部は、紐状部により骨部の他端部と近接又は当接するので、被覆部の開口を塞ぐ蓋として機能する。これにより、営巣材撤去具は、巣の撤去位置から地上までの運搬の間、営巣材の地上への落下を防止する。   After the removed nesting material is placed on the covering portion, the string-like portion slides in the insertion hole from one end side to the other end side of the support column portion. One end side of the bone part is rotated with respect to one end side of the column part. The other end side of the bone part is brought close to the other end side (locking part) of the column part. At this time, since the removed nesting material is placed on the covering portion, the bone portion is bent due to the presence of the nesting material. Specifically, the bone portion bends in an arc shape toward the radially outward direction of the support portion in accordance with the shape of the removed nesting material. The strut is contracted in the longitudinal direction in accordance with the bending of the bone. Since the covering portion covers between adjacent bone portions, the covering portion is formed in a bag shape having one end side of the supporting column portion as a bottom and the other end side of the supporting column portion as an opening. The string-like portion is locked in the insertion hole to maintain the covering portion in a bag shape. Moreover, since the latching | locking part adjoins or contact | abuts the other end part of the bone part with a string-shaped part, it functions as a lid | cover which closes the opening of a coating | coated part. Thereby, the nesting material removal tool prevents the nesting material from falling to the ground during transportation from the nest removal position to the ground.

また、本発明に係る営巣材撤去具は、骨部の他端側先端に、構造物に骨部を固定可能な固定部を有してもよい。   Moreover, the nesting material removal tool which concerns on this invention may have a fixing | fixed part which can fix a bone part to a structure in the other end side tip of a bone part.

かかる構成によれば、骨部の他端側先端が鉄塔等の構造物に固定されるので、営巣材撤去具を構造物に対して安定して設置することができる。   According to such a configuration, since the tip of the other end side of the bone part is fixed to a structure such as a steel tower, the nesting material removing tool can be stably installed on the structure.

また、本発明に係る営巣材撤去具において、被覆部は、隣り合う骨部間の距離を可変とすべく骨部に取り付けられてもよい。   Further, in the nesting material removing tool according to the present invention, the covering portion may be attached to the bone portion so that the distance between the adjacent bone portions is variable.

かかる構成によれば、被覆部が、隣り合う骨部間の距離を可変することができるので、骨部の可撓性を高めることができる。   According to this structure, since the coating | coated part can change the distance between adjacent bone parts, the flexibility of a bone part can be improved.

また、本発明に係る営巣材撤去具において、紐状部は、長手方向に沿って所定の間隔で径を太くした膨大部を有し、挿通孔は、膨大部を挿通可能な第１挿通孔と、第１挿通孔に連設され、膨大部を挿通不能な第２挿通孔を有してもよい。   Moreover, in the nesting material removing tool according to the present invention, the string-like portion has a huge portion whose diameter is increased at predetermined intervals along the longitudinal direction, and the insertion hole is a first insertion hole through which the huge portion can be inserted. And a second insertion hole that is continuous with the first insertion hole and cannot be inserted through the enormous portion.

かかる構成によれば、紐状部が、第１挿通孔の位置に置かれることで、第１挿通孔は、膨大部を挿通することができる。これにより、紐状部は、挿通孔内を自由に移動することができる。一方、紐状部が、第２挿通孔の位置に置かれることで、第２挿通孔は、膨大部を挿通することができない。これにより、紐状部は、第２挿通孔の端部と膨大部との係止により、膨大部の位置以上、挿通孔内を自由に移動することができない。したがって、膨大部及び第２挿通孔は、紐状部の係止手段として機能する。これにより、営巣材撤去具の設置位置において、骨部及び被覆部を支柱部から自由に離間させることができるとともに、決定された、骨部及び被覆部の支柱部からの離間距離で、骨部及び被覆部を固定することができる。   According to such a configuration, the string-like portion is placed at the position of the first insertion hole, so that the first insertion hole can pass through the enormous portion. Thereby, the string-like portion can freely move in the insertion hole. On the other hand, a string-like part is put in the position of the 2nd penetration hole, and the 2nd penetration hole cannot penetrate a huge part. Thereby, the string-like part cannot move freely in the insertion hole more than the position of the enormous part due to the engagement between the end part of the second insertion hole and the enormous part. Therefore, the enormous part and the second insertion hole function as a locking means for the string-like part. Thereby, at the installation position of the nesting material removal tool, the bone part and the covering part can be freely separated from the support part, and the bone part and the covering part can be separated at a determined distance from the support part. And the covering portion can be fixed.

以上の如く、本発明に係る営巣材撤去具によれば、巣の撤去時及び運搬時を通じて、営巣材を飛散又は落下させないというすぐれた効果を奏する。   As described above, the nesting material removing tool according to the present invention has an excellent effect that the nesting material is not scattered or dropped during removal and transportation of the nest.

In addition, the covering portion 30 can change the degree of bending of the folds 301, 302, and 303 according to the bending of the bone portion main body 201. Accordingly, the degree of spread can be changed, and the flexibility of the bone body 201 is ensured. That is, the covering portion 30 is attached to the bone portion main body 201 with a tolerance that allows the distance between the adjacent bone portion main bodies 201 to be changed by the bending of the bone portion main body 201.

紐状部４０は、係止部５０に挿通される紐状部本体４０１と、紐状部本体４０１の一端側に設けられるフック部４０２とを有する。   The string-like part 40 has a string-like part main body 401 inserted through the locking part 50 and a hook part 402 provided on one end side of the string-like part main body 401.

紐状部本体４０１は、骨部２０の数と同数設けられる。紐状部本体４０１は、一端側でフック部４０２に接続され、他端側で、複数の骨部本体２０１の他端側にそれぞれ接続される。例えば、紐状部本体４０１のそれぞれは、一端側でフック部４０２に接続され、他端側で、８本の骨部本体２０１の他端側にそれぞれ接続される。紐状部本体４０１は、係止部５０と連結部２０３との間の距離をより短くするように、係止部５０の挿通孔を摺動することで、図１（ａ）及び図１（ｂ）に示すように、支柱部１０の他端側と骨部２０の他端側とを近接させる。これにより、紐状部本体４０１は、被覆部３０を袋状にして、持ち運び可能な状態とする。   As many string-like main bodies 401 as the number of bone parts 20 are provided. The string-like part main body 401 is connected to the hook part 402 on one end side, and is connected to the other end side of the plurality of bone part main bodies 201 on the other end side. For example, each of the string-like portion main bodies 401 is connected to the hook portion 402 on one end side, and is connected to the other end sides of the eight bone portion main bodies 201 on the other end side. The string-like portion main body 401 slides through the insertion hole of the locking portion 50 so as to shorten the distance between the locking portion 50 and the connecting portion 203, whereby FIG. 1 (a) and FIG. As shown to b), the other end side of the support | pillar part 10 and the other end side of the bone part 20 are made to adjoin. Thereby, the string-like-part main body 401 makes the covering part 30 into a bag shape so that it can be carried.

一方、紐状部本体４０１は、係止部５０と連結部２０３との間の距離をより長くすることで、図２に示すように、支柱部１０の他端側と骨部２０の他端側とを離間させる。これにより、紐状部本体４０１は、被覆部３０を展開して、撤去した巣の営巣材を受けることができる状態とする。なお、紐状部本体４０１は、係止部５０と連結部２０３との間の距離を最大にしたとしても、骨部本体２０１の他端側が係止部５０と軸部２０２との間の高さ位置に位置する程度の長さであるのが好ましい。これにより、紐状部本体４０１は、可撓性を有する骨部本体２０１を、支柱部１０の一端側から他端側に向けて円弧状に撓んだ状態で維持する。   On the other hand, the string-like body 401 has a longer distance between the locking portion 50 and the connecting portion 203, so that the other end side of the strut portion 10 and the other end of the bone portion 20 as shown in FIG. Separate the sides. As a result, the string-like portion main body 401 is in a state where the covering portion 30 is expanded to receive the nest material of the removed nest. Even if the distance between the locking portion 50 and the connecting portion 203 is maximized, the other end side of the bone portion main body 201 has a height between the locking portion 50 and the shaft portion 202. It is preferable that the length be in the position. Thereby, the string-like part main body 401 maintains the flexible bone part main body 201 in a state of being bent in an arc shape from one end side to the other end side of the support column part 10.

また、紐状部本体４０１は、図４に示すように、長手方向に沿って所定の間隔で径を太くした膨大部４０３を有する。より詳しくは、紐状部本体４０１は、長手方向に沿って所定の間隔で径外方向に紐状部本体４０１の周面から突出する。   Further, as shown in FIG. 4, the string-like portion main body 401 has a huge portion 403 whose diameter is increased at predetermined intervals along the longitudinal direction. More specifically, the string-like portion main body 401 protrudes from the peripheral surface of the string-like portion main body 401 in the radially outward direction at a predetermined interval along the longitudinal direction.

フック部４０２は、紐状部本体４０１の一端側に接続される。また、フック部４０２は、フック保持部１０４に着脱自在に構成される。具体的に、フック部４０２は、持ち運び時、フック保持部１０４に取り付けられることで、紐状部本体４０１に持ち運び用の紐としての機能を持たせる。一方、フック部４０２は、展開時、フック保持部１０４から取り外されることで骨部２０及び被覆部３０を展開可能とするとともに、構造物に営巣材撤去具１全体を吊り下げるためのフックとして利用される。   The hook portion 402 is connected to one end side of the string-like portion main body 401. The hook unit 402 is configured to be detachable from the hook holding unit 104. Specifically, the hook unit 402 is attached to the hook holding unit 104 when being carried, so that the string-like portion main body 401 has a function as a carrying string. On the other hand, the hook portion 402 is used as a hook for detaching the nesting material removal tool 1 from the structure while being able to deploy the bone portion 20 and the covering portion 30 by being removed from the hook holding portion 104 during deployment. Is done.

係止部５０は、図４に示すように、紐状部本体４０１を挿通する挿通孔５０１を有する。係止部５０は、支柱部１０の他端側に設けられ、円盤状に形成される。挿通孔５０１は、係止部５０の厚さ方向に貫通する。また、挿通孔５０１は、骨部２０及び紐状部本体４０１の数と同数、即ち、本実施形態においては８つ設けられる。   As shown in FIG. 4, the locking portion 50 has an insertion hole 501 through which the string-like portion main body 401 is inserted. The latching | locking part 50 is provided in the other end side of the support | pillar part 10, and is formed in a disk shape. The insertion hole 501 penetrates in the thickness direction of the locking part 50. Further, the number of insertion holes 501 is the same as the number of the bone portions 20 and the string-like portion main bodies 401, that is, eight in this embodiment.

挿通孔５０１は、より径の大きい第１挿通孔５０２と、より径の小さい第２挿通孔５０３とを有する。第１挿通孔５０２と、第２挿通孔５０３とは連設されて設けられる。   The insertion hole 501 has a first insertion hole 502 with a larger diameter and a second insertion hole 503 with a smaller diameter. The first insertion hole 502 and the second insertion hole 503 are provided continuously.

第１挿通孔５０２は、紐状部本体４０１を挿通可能であるとともに、膨大部４０３を挿通可能な径で形成される。第１挿通孔５０２は、紐状部本体４０１及び膨大部４０３を挿通可能であることで、骨部２０と支柱部１０とのなす角度を調整する際に利用される。   The first insertion hole 502 is formed with a diameter through which the string-like body 401 can be inserted and the enormous portion 403 can be inserted. The first insertion hole 502 is used when the angle formed between the bone part 20 and the column part 10 is adjusted by allowing the string-like part main body 401 and the enormous part 403 to be inserted.

第２挿通孔５０３は、係止部５０の径外方向で第１挿通孔５０２に連設される。第２挿通孔５０３は、紐状部本体４０１を挿通可能であるが、膨大部４０３を挿通不能な径で形成される。第２挿通孔５０３は、膨大部４０３を挿通不能であることで、その開口端で膨大部４０３を係止する。これにより、第２挿通部５０３は、骨部２０と支柱部１０とのなす角度を固定する際に利用される。   The second insertion hole 503 is connected to the first insertion hole 502 in the radially outward direction of the locking portion 50. The second insertion hole 503 is formed with a diameter through which the string-like body 401 can be inserted but the enormous portion 403 cannot be inserted. Since the second insertion hole 503 cannot be inserted through the enormous portion 403, the enlarging portion 403 is locked at the opening end thereof. Thereby, the 2nd penetration part 503 is utilized when fixing the angle which the bone part 20 and the support | pillar part 10 make.

本実施形態に係る営巣材撤去具１の構成については以上の通りであり、次に、本実施形態に係る営巣材撤去具１の作用について説明する。   About the structure of the nesting material removal tool 1 which concerns on this embodiment, it is as above, Next, the effect | action of the nesting material removal tool 1 which concerns on this embodiment is demonstrated.

まず、図１（ａ）及び図１（ｂ）に示すように、営巣材撤去具１は、骨部２０及び被覆部３０を折り畳んだ状態で高所にある巣の位置まで運搬される。このとき、紐状部本体４０１が支柱部１０の一端側から他端側に向けて引かれた状態で運搬されることで、骨部２０は、その他端側を支柱部１０の他端側に近接した状態に維持される。また、被覆部３０は、折り畳まれた状態に維持される。   First, as shown in FIGS. 1 (a) and 1 (b), the nesting material removal tool 1 is transported to the nest position at a high place with the bone part 20 and the covering part 30 folded. At this time, the bone portion 20 is transported in a state where the string-like portion main body 401 is pulled from one end side to the other end side of the column portion 10, so that the bone portion 20 has the other end side on the other end side of the column portion 10. Stay in close proximity. Moreover, the coating | coated part 30 is maintained in the folded state.

営巣材撤去具１が巣の位置まで持ち運ばれると、フック部４０２は、フック保持部１０４から取り外される。そして、紐状部本体４０１は、係止部５０の第１挿通孔５０２側を挿通する位置に移動される。これにより、紐状部本体４０１は、係止部５０の第１挿通孔５０２内を摺動可能になる。   When the nesting material removing tool 1 is carried to the nest position, the hook portion 402 is removed from the hook holding portion 104. Then, the string-like portion main body 401 is moved to a position where it is inserted through the first insertion hole 502 side of the locking portion 50. Thereby, the string-like portion main body 401 can slide in the first insertion hole 502 of the locking portion 50.

紐状部本体４０１は、係止部５０と連結部２０３との間の距離を長くするように、第１挿通孔５０１内を摺動することで、図３に示すように、骨部２０及び被覆部３０を展開する。そして、紐状部本体４０１が第２挿通孔５０３に位置されることで、骨部２０及び被覆部３０は、展開した状態で固定される。このとき、複数の骨部２０の他端側のそれぞれは、支柱部１０を中心として放射状に広がるように、紐状部本体４０１に張力を与える。すなわち、複数の骨部２０の他端側のそれぞれは、支柱部１０を中心として、紐状部本体４０１を係止部５０の径外方向へ付勢するように、紐状部本体４０１に張力を与える。これにより、紐状部本体４０１は、第１挿通孔５０２から第２挿通孔５０３へ向かう方向に付勢されるので、膨大部４０３は、第２挿通孔５０３の開口（端部）に係止され、その状態で維持される。したがって、膨大部４０３及び第２挿通孔５０３は、紐状部４０の係止手段として機能する。   As shown in FIG. 3, the string-like body 401 is slid in the first insertion hole 501 so as to increase the distance between the locking portion 50 and the connecting portion 203. The covering part 30 is developed. And the bone-like part main body 401 is positioned in the 2nd penetration hole 503, and the bone part 20 and the coating | coated part 30 are fixed in the expand | deployed state. At this time, each of the other ends of the plurality of bone portions 20 applies tension to the string-like portion main body 401 so as to spread radially around the support column portion 10. That is, each of the other ends of the plurality of bone portions 20 is tensioned to the string-like portion main body 401 so as to urge the string-like portion main body 401 in the radially outward direction of the locking portion 50 around the column portion 10. give. As a result, the string-like portion main body 401 is biased in the direction from the first insertion hole 502 toward the second insertion hole 503, so that the enormous portion 403 is locked to the opening (end) of the second insertion hole 503. And maintained in that state. Therefore, the enormous part 403 and the second insertion hole 503 function as locking means for the string-like part 40.

この状態で、フック部４０２は、構造物の高所に取り付けられる。これにより、例えば、図５（ａ）に示すように、営巣材撤去具１は、構造物の高所に取り付けられる。より具体的に、フック部４０２は、構造物の高所にある鉄骨２１に取り付けられる。これにより、営巣撤去具１は、構造物の高所にある鉄骨２１に取り付けられる。   In this state, the hook portion 402 is attached to a high place of the structure. Thereby, for example, as shown to Fig.5 (a), the nesting material removal tool 1 is attached to the high place of a structure. More specifically, the hook portion 402 is attached to the steel frame 21 at the height of the structure. Thereby, the nesting removal tool 1 is attached to the steel frame 21 at the height of the structure.

固定部２０４は、構造物の高所に固定される。より詳しくは、複数の骨部２０に設けられた固定部２０４のそれぞれ又は一部は、構造物の高所に固定される。例えば、図５（ｂ）に示すように、固定部２０４ａ，２０４ｂ，２０４ｃ，２０４ｄ，２０４ｅが、鉄骨２２，２３の角部の形状に合わせて固定される。   The fixing portion 204 is fixed at a high place of the structure. More specifically, each or a part of the fixing portions 204 provided on the plurality of bone portions 20 is fixed at a height of the structure. For example, as shown in FIG. 5 (b), the fixing portions 204 a, 204 b, 204 c, 204 d, and 204 e are fixed according to the shape of the corners of the steel frames 22 and 23.

骨部本体２０１は、構造物の形状に合わせて撓む。例えば、図５（ｂ）に示すように、骨部本体２０１ｂ，２０１ｄが、鉄骨２２，２３の角部の形状に合わせて撓む。被覆部３０は、骨部本体２０１ｂ，２０１ｄの撓みに対応して、折目３０１，３０２，３０３で折り曲げられ又は伸ばされる。これにより、被覆部３０の端部は、構造物と隙間を作ることなく密接する。   The bone part main body 201 bends according to the shape of the structure. For example, as shown in FIG. 5B, the bone main bodies 201 b and 201 d bend according to the shape of the corners of the steel frames 22 and 23. The covering portion 30 is bent or stretched at the folds 301, 302, and 303 corresponding to the bending of the bone portion main bodies 201b and 201d. Thereby, the edge part of the coating | coated part 30 closely_contact | adheres without making a clearance gap with a structure.

この状態で、被覆部３０は、撤去された巣の営巣材を受ける。巣が撤去された後、フック部４０２は、構造物から取り外される。そして、紐状部４０１は、第１挿通孔５０２の位置に移動され、フック部４０２を係止部５０から離間する方向に第１挿通孔５０２内を摺動する。これにより、紐状部本体４０１は、連結部２０３を介して、骨部本体２０１の他端側を支柱部１０の他端側に近接させる。骨部本体２０１の他端側が支柱部１０の他端側に近接することで、被覆部３０は、折り畳まれて、袋状にされる。   In this state, the covering portion 30 receives the nesting material of the removed nest. After the nest is removed, the hook portion 402 is removed from the structure. The string-like portion 401 is moved to the position of the first insertion hole 502 and slides in the first insertion hole 502 in a direction in which the hook portion 402 is separated from the locking portion 50. Accordingly, the string-like portion main body 401 brings the other end side of the bone portion main body 201 close to the other end side of the support column portion 10 via the connecting portion 203. When the other end side of the bone part main body 201 comes close to the other end side of the column part 10, the covering part 30 is folded into a bag shape.

図６に示すように、被覆部３０は、袋状にされることで内部に撤去された営巣材Ｘを内包する形状となる。骨部本体２０１は、営巣材Ｘの形状に合わせて第２支柱部１０２の径外方向に撓む。紐状部本体４０１が骨部本体２０１の他端縁を係止部５０に近接又は当接するように第１挿通孔５０２内を移動することで、第１支柱部１０１は、第２支柱部１０２の内部に押し込まれる。したがって、被覆部３０は、開口部を係止部５０で閉じられた状態となる。これにより、営巣材撤去具１は、営巣材の運搬においても、営巣材Ｘを落下又は飛散させない。   As shown in FIG. 6, the covering portion 30 has a shape that encloses the nesting material X that has been removed into the bag shape. The bone main body 201 bends in the radially outward direction of the second support column 102 in accordance with the shape of the nesting material X. By moving the string-like main body 401 in the first insertion hole 502 so that the other end of the bone main body 201 comes close to or comes into contact with the locking portion 50, the first strut portion 101 becomes the second strut portion 102. It is pushed inside. Therefore, the covering portion 30 is in a state where the opening is closed by the locking portion 50. Thereby, the nesting material removal tool 1 does not drop or scatter the nesting material X even in the transportation of the nesting material.

以上より、本実施形態に係る営巣材撤去具１は、構造物の高所に形成された巣を撤去するのに用いられる営巣材撤去具１であって、長尺状に形成され、長手方向に伸縮可能な支柱部１０と、可撓性を有し、長尺状に形成され、一端側が支柱部１０の一端側に回動自在に支持されることで、他端側が支柱部１０の他端側に対して接離可能に設けられる複数の骨部２０と、それぞれ隣り合う骨部２０間を覆うように、複数の骨部２０に取り付けられるシート状の被覆部３０と、複数の骨部２０の他端側のそれぞれに取り付けられる紐状部４０と、支柱部１０の他端側に設けられ、紐状部４０を挿通する挿通孔５０１を有し、挿通孔５０１において紐状部４０を係止可能な係止部５０とを備える。   As mentioned above, the nesting material removal tool 1 which concerns on this embodiment is the nesting material removal tool 1 used for removing the nest formed in the high place of the structure, Comprising: It is formed in elongate shape and is longitudinal direction. The support column 10 can be expanded and contracted, and is flexible and is formed in an elongated shape. One end side of the support column 10 is rotatably supported by one end side of the support column 10, and the other end side is the other of the support column 10. A plurality of bone portions 20 provided so as to be able to contact and separate from the end side, a sheet-like covering portion 30 attached to the plurality of bone portions 20 so as to cover each adjacent bone portion 20, and a plurality of bone portions 20 has a string-like portion 40 to be attached to each of the other end sides, and an insertion hole 501 that is provided on the other end side of the support column portion 10 and passes through the string-like portion 40. The string-like portion 40 is inserted into the insertion hole 501. And a locking portion 50 that can be locked.

かかる構成によれば、営巣材撤去具１を運搬する際には、被覆部３０が袋状に折り畳まれるので、営巣材撤去具１の運搬を容易にするとともに、撤去した巣の営巣材Ｘを落下又は飛散させずに運搬できる。一方、営巣材撤去具１を設置する際には、骨部２０が構造物に合わせて撓むので、構造物に合わせて営巣材撤去具１を設置することができ、営巣材Ｘを落下又は飛散させずに巣を撤去することができる。   According to such a configuration, when the nesting material removing tool 1 is transported, the covering portion 30 is folded into a bag shape, so that the nesting material removing tool 1 is easily transported and the nesting material X of the removed nest is removed. Can be transported without falling or splashing. On the other hand, when the nesting material removal tool 1 is installed, since the bone part 20 bends in accordance with the structure, the nesting material removal tool 1 can be installed according to the structure, and the nesting material X is dropped or dropped. The nest can be removed without splashing.

また、本実施形態に係る営巣材撤去具１は、骨部２０の他端側先端に、構造物に骨部２０を固定可能な固定部２０４を有する。   Moreover, the nesting material removal tool 1 according to the present embodiment has a fixing portion 204 that can fix the bone portion 20 to the structure at the tip of the other end side of the bone portion 20.

これにより、骨部２０の他端側先端が鉄塔等の構造物に固定されるので、営巣材撤去具１を構造物に対して安定して設置することができる。   Thereby, since the front-end | tip side of the other end side of the bone part 20 is fixed to structures, such as a steel tower, the nesting material removal tool 1 can be stably installed with respect to a structure.

また、本実施形態に係る営巣材撤去具１において、被覆部３０は、隣り合う骨部２０間の距離を可変とすべく骨部２０に取り付けられる。   Moreover, in the nesting material removal tool 1 according to the present embodiment, the covering portion 30 is attached to the bone portion 20 so that the distance between the adjacent bone portions 20 can be changed.

これにより、被覆部３０が、隣り合う骨部２０間の距離を可変にして骨部２０に取り付けられるので、骨部２０の可撓性を高めることができる。   Thereby, since the coating | coated part 30 is attached to the bone part 20 by making the distance between the adjacent bone parts 20 variable, the flexibility of the bone part 20 can be improved.

また、本実施形態に係る営巣材撤去具１において、紐状部４０は、長手方向に沿って所定の間隔で径を太くした膨大部４０３を有し、挿通孔５０１は、膨大部４０３を挿通可能な第１挿通孔５０２と、第１挿通孔５０２に連設され、膨大部を挿通不能な第２挿通孔５０３とを有する。   Further, in the nesting material removing tool 1 according to the present embodiment, the string-like portion 40 has a huge portion 403 whose diameter is increased at a predetermined interval along the longitudinal direction, and the insertion hole 501 is inserted through the huge portion 403. The first insertion hole 502 and the second insertion hole 503 that are connected to the first insertion hole 502 and cannot be inserted through the enormous portion.

これにより、紐状部４０が、第１挿通孔５０２の位置に置かれることで、第１挿通孔５０２は、膨大部４０３を挿通することができる。これにより、紐状部４０は、挿通孔５０１内を自由に移動することができる。一方、紐状部４０が、第２挿通孔５０３の位置に置かれることで、第２挿通孔５０３は、膨大部４０３を挿通することができない。これにより、紐状部４０は、第２挿通孔５０３の端部による膨大部４０３との係止により、挿通孔５０１内を自由に移動することができない。したがって、膨大部４０３及び第２挿通孔５０３は、紐状部４０の係止手段として機能する。これにより、営巣材撤去具１の設置位置において、骨部２０及び被覆部３０を支柱部１０から自由に離間させることができるとともに、決定された、骨部２０及び被覆部３０の支柱部１０からの離間距離で、骨部２０及び被覆部３０を固定させることができる。   Thereby, the string-like portion 40 is placed at the position of the first insertion hole 502, so that the first insertion hole 502 can pass through the enormous portion 403. Thereby, the string-like part 40 can move freely in the insertion hole 501. On the other hand, the string-like portion 40 is placed at the position of the second insertion hole 503 so that the second insertion hole 503 cannot pass through the enormous portion 403. Thereby, the string-like part 40 cannot move freely in the insertion hole 501 due to the engagement with the enormous part 403 by the end of the second insertion hole 503. Therefore, the enormous part 403 and the second insertion hole 503 function as locking means for the string-like part 40. Thereby, in the installation position of the nesting material removal tool 1, while being able to freely space | separate the bone part 20 and the coating | coated part 30 from the support | pillar part 10, from the determined support | pillar part 10 of the bone | frame part 20 and the coating | coated part 30 The bone portion 20 and the covering portion 30 can be fixed with a separation distance of.

Moreover, the structure which can be removed from the other end part of the 2nd support | pillar part 102 may be sufficient as this hook. Thereby, it is possible to attach the nesting material removing tool 1 to the structure by a more flexible method, not only when the hook portion 402 is used.

また、本実施形態に係る営巣材撤去具１おいては、挿通孔５０１が、第１挿通孔５０２及び第２挿通孔５０３を連設した構成で説明した。これに代わり、図７（ａ）に示すように、挿通孔５０１は、１つの貫通孔で、貫通孔の内面５０４（縁面）にゴム等の摩擦係数の高い素材を有する構成であってもよい。この場合、紐状部本体４０１は、膨大部４０３を有しない構成であってよい。構造物に営巣撤去具１を取り付けるべく、骨部２０及び被覆部３０が展開された際には、紐状部本体４０１の周面は、挿通孔５０１の開口端部に押し付けられる。そして、紐状部本体４０１の周面が内面５０４の端縁に係止されることで、紐状部本体４０１及び挿通孔５０１とが係止手段として機能してもよい。   Moreover, in the nesting material removal tool 1 according to the present embodiment, the insertion hole 501 has been described with the configuration in which the first insertion hole 502 and the second insertion hole 503 are connected. Instead, as shown in FIG. 7A, the insertion hole 501 is a single through hole, and the inner surface 504 (edge surface) of the through hole may have a material having a high coefficient of friction such as rubber. Good. In this case, the string-like portion main body 401 may be configured without the enormous portion 403. When the bone part 20 and the covering part 30 are deployed in order to attach the nesting tool 1 to the structure, the circumferential surface of the string-like part main body 401 is pressed against the opening end of the insertion hole 501. And the string-like-part main body 401 and the insertion hole 501 may function as a locking means by locking the peripheral surface of the string-like-part main body 401 to the edge of the inner surface 504.

また、図７（ｂ）に示すように、挿通孔５０１は、上記のように貫通孔の内面５０４にゴム等の摩擦係数の高い素材を有する構成であるとともに、支柱部１０の一端側から他端側に向けて径の細くなる断面テーパ状の構成であってもよい。このようにすることで、紐状部本体４０１は、内面５０４の短径部分で係止され、紐状部本体４０１及び挿通孔５０１とが係止手段として機能してもよい。   Further, as shown in FIG. 7B, the insertion hole 501 is configured to have a material having a high coefficient of friction such as rubber on the inner surface 504 of the through hole as described above, and the other from the one end side of the support column 10. A cross-sectional taper configuration in which the diameter decreases toward the end side may be used. By doing so, the string-like portion main body 401 may be locked at the short diameter portion of the inner surface 504, and the string-like portion main body 401 and the insertion hole 501 may function as locking means.

また、図８に示すように、係止部５０は、円盤状の第１係止部５１と、第１係止部５１と同径であり、挿通孔５０１の軸位置を一致した状態で第１係止部５１と当接して設けられる第２係止部５２を有していてもよい。第１係止部５１は、支柱部１０に固定され、第２係止部５２は、支柱部１０を軸として回動自在に構成される。紐状部本体４０１が挿通孔５０１に挿通された状態で、第２挿通孔５２が回動されることで、紐状部本体４０１は、第１挿通孔５１及び第２挿通孔５２の境において、かしめられた状態になる。これにより、係止部５０は、紐状部本体４０１を係止することができる。なお、第２挿通孔５２は、紐状部本体４０１をかしめるのに十分な回動位置で、その状態を維持する図示しない維持手段を有しているのが好ましい。また、第２係止部５０２に対して、第１係止部５０が回動する構成としてもよい。   Further, as shown in FIG. 8, the locking portion 50 has the same diameter as the disk-shaped first locking portion 51 and the first locking portion 51, and the axial positions of the insertion holes 501 coincide with each other. You may have the 2nd latching | locking part 52 provided in contact with the 1 latching | locking part 51. FIG. The 1st latching | locking part 51 is fixed to the support | pillar part 10, and the 2nd latching | locking part 52 is comprised rotatably with the support | pillar part 10 as an axis | shaft. The second insertion hole 52 is rotated in a state where the string-like body 401 is inserted into the insertion hole 501, so that the string-like body 401 is at the boundary between the first insertion hole 51 and the second insertion hole 52. , It will be squeezed. Thereby, the latching | locking part 50 can latch the string-shaped part main body 401. FIG. In addition, it is preferable that the 2nd insertion hole 52 has a maintenance means (not shown) which maintains the state in the rotation position sufficient to crimp the string-like part main body 401. Further, the first locking part 50 may be configured to rotate with respect to the second locking part 502.

また、本実施形態における営巣材撤去具１において、被覆部３０は、骨部２０から脱着可能な構成であってもよい。例えば、営巣撤去具１が電柱に取り付けられる場合、被覆部３０は、その一部が骨部２０から取り外されることで、電柱の形状に合わせて設置可能となる。   Further, in the nesting material removing tool 1 in the present embodiment, the covering portion 30 may be configured to be removable from the bone portion 20. For example, when the nesting removal tool 1 is attached to a utility pole, the covering portion 30 can be installed in accordance with the shape of the utility pole by removing a part of the covering portion 30 from the bone portion 20.
