Description

本発明は、電柱を支持している支線にツタ等の蔓性の植物が巻き上がるのを防ぐ蔓巻防止装置に関し、該蔓巻防止装置を支線に対し簡単に取り付ける方法に関するものである。   The present invention relates to a vine prevention device that prevents a vine plant such as ivy from rolling up on a branch line supporting a utility pole, and relates to a method for easily attaching the vine prevention device to a branch line.

ツタ等の蔓性植物が生い茂る場所では、電柱を支持するために地上から斜めに張られた支線にその蔓性植物が巻き上がり電柱の上部まで達することがあり、これが原因で地絡事故を発生させるおそれがあった。
このように蔓性植物が支線に巻き上がるのを防止するための蔓巻防止装置が下記特許文献１、２に示されており、特許文献１に示された蔓巻防止装置は、筒状の防止具本体内に支線を挟着する爪部材を備えることにより支線に対し強い挟着力が得られるものである。また、特許文献２に示された蔓巻防止装置は、支線に取り付けられた固定体を防止具本体が包み込み、内包後に固定体と防止具本体が一体化する構造である。しかしこれらの蔓巻防止装置は、支線が通常は複数本の鋼線を螺旋状に撚り合わせた索条からなるものであったので、風によって該防止具本体に回転トルクが掛かるとその鋼線に沿って該防止具本体が回転し、ずり落ちるおそれがあった。 In locations where vines such as ivy grow thickly, the vines may roll up to the branch line that is slanted from the ground to support the utility pole, reaching the top of the utility pole, causing a ground fault There was a risk of causing it.
As described above, Patent Documents 1 and 2 show prevention devices for preventing the vines from being wound on the branch lines. The prevention device for the vines shown in Patent Document 1 has a cylindrical shape. A strong clamping force can be obtained for the branch line by providing a claw member for clamping the branch line in the prevention tool main body. In addition, the anti-wound device shown in Patent Document 2 has a structure in which a fixing body attached to a branch line is wrapped by a prevention tool main body, and the fixing body and the prevention tool main body are integrated after inclusion. However, since these branching prevention devices usually consist of ropes in which a plurality of steel wires are spirally twisted, if the rotational torque is applied to the main body of the prevention device by the wind, There was a possibility that the main body of the preventive device would rotate along the axis and slip off.

また、下記特許文献３に示された蔓巻防止装置は、支線にＵボルトを固定し、該Ｕボルトの上部に円筒状の防止具本体が支持されるように構成されたものであり、特許文献４に示された蔓巻防止装置は、板状の防止具本体を支持してなるものであり、これらの特許文献に示された構成では、防止具本体が自由に回転し得るので、防止具本体の回転トルクがＵボルト等の固定体に伝わらず、固定体が回転しないために上記のようなずり落ちが防止される。
また、下記特許文献５に示された蔓巻防止装置は、支線に取り付けられた固定体を防止具本体が包み込み、内包後に固定体に対して防止具本体が回転自在に取り付けられ、風によって該防止具本体が回転しても固定体に回転トルクが掛かることなく、ずり落ちが防止されるようにしたものである。 Moreover, the anti-wound device shown in Patent Document 3 below is configured such that a U-bolt is fixed to a branch line, and a cylindrical prevention device main body is supported on the upper portion of the U-bolt. The anti-wound device shown in Document 4 is configured to support a plate-shaped prevention tool body, and in the configurations shown in these patent documents, the prevention tool body can rotate freely, so that prevention is achieved. Since the rotational torque of the tool body is not transmitted to a fixed body such as a U-bolt and the fixed body does not rotate, the above-described sliding is prevented.
Further, in the anti-wound device shown in Patent Document 5 below, the main body of the protective device wraps the fixed body attached to the branch line, and the main body of the protective device is rotatably attached to the fixed body after inclusion, Even if the preventer main body rotates, the stationary body is not subjected to rotational torque, and slipping is prevented.

ところで、これらの蔓巻防止具のように、防止具本体と固定体とからなるものは、固定体を支線に取り付ける作業と、防止具本体を支線に取り付ける作業とが必要であるので少なくとも２回の取付作業が必要であって面倒であるとともに、雑草が多く生えた足場が悪い環境でこのような作業をしなければならないので危険であった。
また、防止具本体は、蔓巻を防ぐために太くて長く形成されたものであるので、これを一方の手で支えながら爪部材やボルトを操作し支線に固定するといった取付作業は、特に一人の作業者によって行うことは容易でなかった。
本発明は、蔓巻防止具の風などによるずり落ちを防止するという効果を維持しつつ、かつ蔓巻防止具の上記のような取付作業上の問題点を解決しようとするものである。 By the way, since these preventive devices are composed of a prevention tool main body and a fixed body, an operation of attaching the fixed body to the branch line and an operation of attaching the prevention tool main body to the branch line are required, so at least twice. It is dangerous because it is necessary to carry out such work in an environment where a lot of weeds grow and the scaffolding is poor.
In addition, since the main body of the prevention tool is thick and long to prevent the swarm, the mounting work such as operating the claw member or bolt and fixing it to the branch line while supporting it with one hand is particularly difficult for one person. It was not easy to do by an operator.
The present invention is intended to solve the above-described problems associated with the installation of the anti-winding tool while maintaining the effect of preventing the anti-winding tool from slipping off due to wind or the like.

The main body 1 is formed by blowing a synthetic resin having weather resistance so that the semi-cylindrical body 1a and the semi-cylindrical body 1b are integrally formed through a thin hinge portion 2 on one side edge. The Concave grooves 4a and 4b having a semicircular cross section for guiding a branch line, which will be described later, are formed on substantially the center lines of the inner surfaces 3a and 3b of the semi-cylindrical bodies 1a and 1b, respectively. The engaging portion 5a is recessed in the side edge opposite to the hinge portion 2, and the engaging claw 5b protrudes from the side edge opposite to the hinge portion 2 of the semi-cylindrical body 1b. Further, a protrusion 6a is formed around the inner surface 3a of the semi-cylindrical body 1a, and a recess 6b into which the protrusion 6a is fitted is formed around the inner surface 3b of the semi-cylindrical body 1b. Reference numerals 7a and 7b denote rotational braking members made of an elastic material such as rubber installed in a part of the concave grooves 4a and 4b. The rotational braking member is formed by integrally forming a plurality of fins in contact with the branch line on the inner peripheral edge. Become. 8a is a guide piece protruding from one side edge of the groove 4a, and 8b is a recess formed by expanding a part of the groove 4b so that the guide piece can be accommodated. Further, half-cut mushroom-like protrusions 9a and 9b having a bulging tip are integrally formed at one end of the semi-cylindrical bodies 1a and 1b. And the screw hole-shaped engaging part 10 used as the temporary latching means mentioned later is formed in the outer peripheral part of the protrusion part 9a of one half cylindrical body 1a. Further, a hook-like hook 11a is fixed by a screw 11c near the concave groove 4a of one half-cylindrical body 1a on the side opposite to the protruding portion 9a. 11b is a recess formed by expanding a part of the groove 4b of the other semi-cylindrical body 1b so that the hook 11a can be accommodated.

この防止具本体１は、蝶番部２を屈曲させて半筒状体１ａ，１ｂの相対する内面３ａ，３ｂを合着し、突条６ａを凹条６ｂに嵌合し、係合爪５ａを係合部５ｂに係合することにより円筒形になる。円筒形にしたときのこの防止具本体１の直径Ｗおよび長さＬは、蔓性植物が巻き付かない寸法（例えば、直径１８０ｍｍ、長さ１２００ｍｍ程度）にする。   In the main body 1 of the preventive device, the hinge portion 2 is bent so that the opposing inner surfaces 3a and 3b of the semi-cylindrical bodies 1a and 1b are joined together, the protrusion 6a is fitted into the recess 6b, and the engaging claw 5a is attached. A cylindrical shape is obtained by engaging with the engaging portion 5b. The diameter W and the length L of the prevention device main body 1 when it is formed into a cylindrical shape are set to dimensions (for example, a diameter of 180 mm and a length of about 1200 mm) that the vines do not wind.

また、この防止具本体１を支持するための固定体２０を図２に開状態にて示す。該固定体２０は、耐候性を有する合成樹脂を射出成形することにより半円筒状の一対の半割体２０ａと半割体２０ｂとが形成され、該半割体２０ａおよび半割体２０ｂの一側縁に形成された蝶番部２１ａ，２１ｂに支軸２２を貫挿することにより、該半割体２０ａと半割体２０ｂとが開閉可能なるように連結される。該半割体２０ａ，２０ｂの内面中心線上に支線を通すための凹溝２３ａ，２３ｂが形成され、また、該半割体２０ａの蝶番部２１ａと反対側側縁に係合部２４ａが凹設され、該半割体２０ｂの蝶番部２１ｂと反対側側縁には係合爪２４ｂが突設される。また、図３にも示したように、該半割体２０ａおよび半割体２０ｂの一端部に前記防止具本体１の突出部９ａ，９ｂを外側から抱持し得る内径を有した筒状連結部２５ａ，２５ｂが一体に形成される。また、該半割体２０ａおよび半割体２０ｂの他端部には、スカート部２６ａ，２６ｂが一体に形成される。２７は半割体２０ａ内および半割体２０ｂ内に形成された補強用リブである。   Moreover, the fixed body 20 for supporting this prevention tool main body 1 is shown in an open state in FIG. The fixed body 20 is formed by injection molding a weather-resistant synthetic resin to form a pair of half-cylindrical halves 20a and 20b, and one of the halves 20a and 20b. By inserting the support shaft 22 into the hinge portions 21a and 21b formed on the side edges, the half body 20a and the half body 20b are connected so as to be openable and closable. Concave grooves 23a and 23b for passing branch lines are formed on the inner center lines of the halves 20a and 20b, and an engaging part 24a is recessed on the side edge opposite to the hinge part 21a of the halves 20a. An engaging claw 24b is projected from the side edge of the half body 20b opposite to the hinge portion 21b. Further, as shown in FIG. 3, a cylindrical connection having an inner diameter capable of holding the protruding portions 9a and 9b of the main body 1 from the outside at one end of the half body 20a and the half body 20b. The portions 25a and 25b are integrally formed. Skirt portions 26a and 26b are integrally formed at the other end portions of the half body 20a and the half body 20b. Reference numeral 27 denotes a reinforcing rib formed in the half body 20a and in the half body 20b.

３０は一方の半割体２０ａに設けた挟着機構で、該挟着機構３０は、半割体２０ａの中心線の一側から起立し表面に滑止用ゴム等の弾性材３１が張設された起立壁３２と、該中心線を間に挟むように該起立壁３２の反対側にボルト３３によって回転可能に軸支されたカム形の爪部材３４とからなり、該爪部材３４の表面に滑止用ゴム等の弾性材３５を張設すると共に、該爪部材３４を図１０にも示したようにボルト３３を中心とする矢印の方向に付勢し、該爪部材３４を起立壁３２表面に圧接させる巻きバネ（図示されず）を該爪部材３４内に設けている。３７は該爪部材３４の一側面に突設された指掛用の摘子部である。なお、この一方の半割体２０ａの筒状連結部２５ａには、後述するように仮止のための係合孔２８が貫通状に形成される。   Reference numeral 30 denotes a clamping mechanism provided on one half body 20a. The clamping mechanism 30 is erected from one side of the center line of the half body 20a, and an elastic material 31 such as non-slip rubber is stretched on the surface. And a cam-shaped claw member 34 pivotally supported by a bolt 33 on the opposite side of the upright wall 32 so as to sandwich the center line therebetween, and the surface of the claw member 34 An elastic material 35 such as a non-slip rubber is stretched on the claw member 34, and the claw member 34 is urged in the direction of the arrow about the bolt 33 as shown in FIG. A coil spring (not shown) that is brought into pressure contact with the surface of 32 is provided in the claw member 34. Reference numeral 37 denotes a finger gripper projecting from one side of the claw member 34. In addition, an engagement hole 28 for temporary fixing is formed in a through shape in the cylindrical connecting portion 25a of the one half body 20a as described later.

この蔓巻防止装置は、図３、図４に示したように、一方の半筒状体１ａの突出部９ａを一方の半割体２０ａの筒状連結部２５ａによって抱持させ、該筒状連結部２５ａに形成された係合孔２８に仮係止手段となる摘子ネジ４１を貫挿し該摘子ネジ４１を突出部９ａに形成された係合部１０に螺合することにより、該半筒状体１ａと半割体２０ａとが互いに分離しないように連結し、この連結状態にて工場から出荷される。   As shown in FIG. 3 and FIG. 4, this convolution prevention device holds the projecting portion 9a of one half-cylindrical body 1a by the cylindrical connecting portion 25a of one half-divided body 20a. By inserting a knob screw 41 serving as a temporary locking means into the engaging hole 28 formed in the connecting portion 25a and screwing the knob screw 41 into the engaging portion 10 formed in the protruding portion 9a, The half cylindrical body 1a and the half split body 20a are connected so as not to be separated from each other, and are shipped from the factory in this connected state.

この蔓巻防止装置を取付現場にて電柱（図示せず）の支線４０に取り付けるに際しては、図３に示したように、半筒状体１ａ，１ｂが上側で半割体２０ａ，２０ｂが下側となるように支線４０に前記フック１１ａを引っ掛け、一方の手で半割体２０ａを支えて凹溝４ａに該支線４０を合致させるとともに、他方の手で爪部材３４の摘子部３７に指を掛けて該爪部材３４が起立壁３２の表面から離間するように回転させ、該起立壁３２と該爪部材３４との間隔に支線４０を通して摘子部３７から指を離すことにより図１０に示したように巻きバネの弾性により該爪部材３４を該支線４０に圧接させ、該起立壁３２と該爪部材３４とで支線４０を挟着させる。なお、爪部材３４はカム形に形成されていて矢印の方向に回転すればするほど該爪部材３４の外周と起立壁３２との間隔が狭くなるので、支線４０が強固に狭着され、固定体２０がずり落ちるのが防がれる。そして、係合爪５ｂを係合部５ａに係合することにより、防止具本体１を該支線４０の周囲に取り付ける。なお、このとき、突条６ａが凹条６ｂに嵌合することにより半筒状体１ａと半筒状体１ｂとが隙間なく閉じられる。また、ガイド片８ａが支線４０に近接することにより支線４０のズレが防止される。また、半筒状体１ａと半筒状体１ｂとを閉じたとき、回転制動部材７ａ，７ｂに形成されたフィンが支線４０の外周に摺接することにより、強風時によって防止具本体１が回転するのがある程度抑制される。   When attaching this anti-wound device to the branch line 40 of the utility pole (not shown) at the installation site, as shown in FIG. 3, the semi-cylindrical bodies 1a, 1b are on the upper side and the half-divided bodies 20a, 20b are on the lower side. The hook 11a is hooked on the branch line 40 so as to be on the side, the half body 20a is supported by one hand, the branch line 40 is aligned with the concave groove 4a, and the knob 37 of the claw member 34 is held by the other hand. The fingernail 34 is rotated so that the claw member 34 is separated from the surface of the standing wall 32, and the finger is released from the knob portion 37 through the branch line 40 at a distance between the standing wall 32 and the claw member 34. As shown in FIG. 5, the claw member 34 is brought into pressure contact with the branch line 40 by the elasticity of the winding spring, and the branch line 40 is clamped between the standing wall 32 and the claw member 34. The claw member 34 is formed in a cam shape, and the distance between the outer periphery of the claw member 34 and the standing wall 32 becomes narrower as it rotates in the direction of the arrow, so that the branch line 40 is firmly attached and fixed. The body 20 is prevented from sliding down. And the prevention tool main body 1 is attached to the circumference | surroundings of this branch line 40 by engaging the engaging claw 5b with the engaging part 5a. At this time, the semi-cylindrical body 1a and the semi-cylindrical body 1b are closed without a gap by fitting the protrusions 6a to the recesses 6b. Further, since the guide piece 8a approaches the branch line 40, the shift of the branch line 40 is prevented. Further, when the semi-cylindrical body 1a and the semi-cylindrical body 1b are closed, the fins formed on the rotation braking members 7a and 7b are brought into sliding contact with the outer periphery of the branch line 40, so that the preventer main body 1 is rotated by a strong wind. It is suppressed to some extent.

そして、筒状連結部２５ｂを突出部９ｂの外周に被せると共に、係合爪２４ｂを係合部２４ａに係合し、半割体２０ａ，２０ｂを合着させる。これにより、図５、図８に示されるように突出部９ａ，９ｂが筒状連結部２５ａ，２５ｂによって外側から抱持された状態にて固定体２０および防止具本体１が支線４０に取り付けられる。その後、前記摘子ネジ４１を前記係合部１０、係合孔２８から抜脱し、該仮係止手段による固定体２０と防止具本体１との係止状態を解除する。これにより防止具本体１は固定体２０に対して回転自在となり防止具本体１が強風を受けて回転してもその回転トルクが該固定体２０に伝わらないようになる。   And while connecting the cylindrical connection part 25b on the outer periphery of the protrusion part 9b, the engaging claw 24b is engaged with the engaging part 24a, and the half parts 20a and 20b are united. As a result, as shown in FIGS. 5 and 8, the fixed body 20 and the prevention tool main body 1 are attached to the branch line 40 in a state where the protruding portions 9 a and 9 b are held from the outside by the cylindrical connecting portions 25 a and 25 b. . Thereafter, the knob screw 41 is removed from the engaging portion 10 and the engaging hole 28, and the locked state between the fixed body 20 and the prevention tool main body 1 by the temporary locking means is released. As a result, the prevention tool main body 1 is rotatable with respect to the fixed body 20, and the rotation torque is not transmitted to the fixed body 20 even if the prevention tool main body 1 is rotated by receiving a strong wind.

このように本発明の取付方法では、一方の半筒状体１ａにフック１１ａが設けられているとともに、仮係止手段により半筒状体１ａと半割体２０ａとが予め係止されていることから、該フック１１ａを支線４０に引っ掛けた状態で挟着機構３０を操作すれば、半割体２０ａが分離することなく、一人の作業者によっても一度の操作で簡単かつ迅速に蔓巻防止装置が取り付けられる。   As described above, in the attachment method of the present invention, the hook 11a is provided on one of the semi-cylindrical bodies 1a, and the semi-cylindrical body 1a and the half-divided body 20a are previously locked by the temporary locking means. Therefore, if the clamping mechanism 30 is operated in a state where the hook 11a is hooked on the branch line 40, the half-split body 20a is not separated, and a single operator can easily and quickly prevent the spread of the swarm. The device is installed.

こうして取り付けられた蔓巻防止装置は、固定体２０が支線４０にしっかりと固定され、防止具本体１が回転してもその回転トルクが該固定体２０に伝わらないので、固定体２０が回転してずり落ちるようなことがない。また、強風によって防止具本体１に浮力が掛かっても、該防止具本体１は突出部９ａ，９ｂによって固定体２０と連結されているので、該防止具本体１だけが支線４０に沿って上昇するようなこともなく、防止具本体１が常に適切な高さに保持され、支線４０を蔓性植物が巻き上がるのを防止することができる。   Since the fixing body 20 is firmly fixed to the branch line 40 and the rotation torque of the prevention tool main body 1 is not transmitted to the fixing body 20, the fixing body 20 rotates. There is no such thing as falling down. Even if buoyancy is applied to the main body 1 of the preventive device due to strong winds, the main body 1 of the preventive device is connected to the fixed body 20 by the protruding portions 9a and 9b, so that only the main body 1 of the protective device rises along the branch line 40. Without such a thing, the prevention tool main body 1 is always hold | maintained at suitable height, and it can prevent that a vine plant rolls up the branch line 40. FIG.

また、図９に示されるように、係合部２４ａの外側に空隙２８が形成され、指もしくはドライバーなどの工具で係合爪２４ｂを弾性限度内にて湾曲させることで、係合爪２４ｂと係合部２４ａとはこのように一旦は係合させてもこの係合を解除（リリース）できるようにしている。このため所要メンテナンス時には、係合爪２４ｂと係合部２４ａとの係合を解除して半割体２０ａ，２０ｂを開くことで、該固定体２０内の挟着機構３０を容易に点検することができる。即ち、該固定体２０の筒状連結部２５ａ，２５ｂは突出部９ａ，９ｂを外側から抱持しているので、いちいち防止具本体１を開かなくても該防止具本体１を閉じたままの状態で固定体２０だけを開いて内部の挟着機構３０を簡単に点検し、必要に応じて修理、或いは部品交換をすることができる。なお、挟着機構３０は、摘子部３７に指を掛けて爪部材３４を回転させるだけで支線４０に簡単に取り付けられると共に、取り外す際にも摘子部３７に指を掛けて爪部材３４を回転させるだけで簡単にその挟着状態を解除できる。   Further, as shown in FIG. 9, a gap 28 is formed outside the engaging portion 24a, and the engaging claw 24b is curved within the elastic limit with a tool such as a finger or a screwdriver. In this way, the engagement portion 24a can be released (released) even if it is once engaged. For this reason, at the time of required maintenance, it is possible to easily check the clamping mechanism 30 in the fixed body 20 by releasing the engagement between the engagement claw 24b and the engagement portion 24a and opening the halves 20a and 20b. Can do. That is, since the cylindrical connecting portions 25a and 25b of the fixed body 20 hold the projecting portions 9a and 9b from the outside, the preventer main body 1 remains closed even if the preventer main body 1 is not opened each time. In this state, only the fixed body 20 is opened, the internal clamping mechanism 30 can be simply inspected, and repair or parts replacement can be performed as necessary. The pinching mechanism 30 can be easily attached to the branch line 40 by simply rotating the claw member 34 by placing a finger on the knob 37 and also removing the claw member 34 by hooking the finger on the knob 37 when removing it. The clamping state can be easily released simply by rotating the.

なお、この実施形態で示した仮係止手段は、係合部１０、係合孔２８に摘子ネジ４１を差し込んだものであったが、仮係止手段はこのような摘子ネジに限らず、係合ピン、或いは、結束バンド等、公知の種々の手段を用い得る。図１１に示した実施形態は、先端部に係合用突起が形成されたキー４２を筒状連結部２５ａに形成された係合孔２８から半筒状体１ａの突出部９ａに形成された係合部１０に着脱自在に差し込むことにより該半筒状体１ａと半割体２０ａとが分離不能に連結されるようにしたものであり、該キー４２を抜き差しすることにより仮係止またはその解除を簡単にすることができる。また、図１２に示した実施形態は、プラスチック製の結束バンド４３を突出部９ａに形成された透孔４４と筒状連結部２５ａに形成された透孔４５に挿通することにより仮係止できるようにしたもので、該結束バンド４３は、結止部４３ａに結束解除用の突起４３ｂが形成されており、該突起を指先で摘むことにより結束を解除できる構造であるので、該突起４３ｂを摘んで該結束バンド４３を引っ張り出すことで取付現場においてこの仮係止状態を簡単に解除することができる。   In addition, although the temporary latching means shown by this embodiment inserted the thumbscrew 41 in the engaging part 10 and the engagement hole 28, temporary latching means is restricted to such a thumbscrew. Instead, various known means such as an engagement pin or a binding band can be used. In the embodiment shown in FIG. 11, a key 42 having an engagement protrusion formed at the tip is formed from the engagement hole 28 formed in the cylindrical connecting portion 25a to the protruding portion 9a of the semi-cylindrical body 1a. The semi-cylindrical body 1a and the half-split body 20a are connected to each other so as to be separable by being detachably inserted into the joint portion 10, and temporarily locked or released by inserting and removing the key 42. Can be easy. Further, the embodiment shown in FIG. 12 can be temporarily locked by inserting the plastic binding band 43 through the through hole 44 formed in the protruding portion 9a and the through hole 45 formed in the cylindrical connecting portion 25a. Since the binding band 43 has a structure in which a binding release projection 43b is formed on the fastening portion 43a and the binding can be released by pinching the projection with a fingertip. By pulling and pulling out the binding band 43, the temporarily locked state can be easily released at the installation site.

次に図１３〜図１６に従い本発明の実施例２を説明する。この実施例２は防止具本体内に固定体が内蔵されるものである。図１３に開状態としたものを示すように、防止具本体１は、図１４に示した固定体２０を収容するための半円筒形空隙からなる収納部１５ａ，１５ｂが半筒状体１ａ，１ｂにそれぞれ形成される。そして、一方の収納部１５ａの底壁に仮止のための係合孔２８が貫通状に形成される。なお、実施例１で示したような突出部９ａ，９ｂはこの防止具本体１には形成されない。その他の構造は実施例１と同様であるので同一部分または相当部分に同一符号を付すことにより説明を省略する。   Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, a fixed body is built in the prevention device main body. As shown in the open state in FIG. 13, the preventer main body 1 includes a semi-cylindrical body 1 a, housing portions 15 a and 15 b made of semi-cylindrical gaps for housing the fixed body 20 shown in FIG. 14. 1b, respectively. And the engagement hole 28 for temporary attachment is formed in the bottom wall of one accommodating part 15a in penetration shape. In addition, the protrusions 9a and 9b as shown in the first embodiment are not formed in the preventer main body 1. Since other structures are the same as those of the first embodiment, the same parts or corresponding parts are denoted by the same reference numerals, and the description thereof is omitted.

図１４に示すように、固定体２０は、耐候性を有する合成樹脂を射出成形することにより半円筒状であって両端部に切欠円板状の端板５０が一体に形成され、該端板５０に支線４０を中心部まで導入し得るように切込５１を形成したものであり、実施例１と同様の挟着機構３０が設けられる。該挟着機構３０の起立壁３２の表面に設けられた弾性材３１には挟着時に支線４０がずれ難いようにするために凹欠３２ａを形成している。なお、このようなずれ止めのための凹欠は爪部材３４表面の弾性材３５に形成してもよい。そして、図１５、図１６に示されるように該固定体２０の底部に仮止のためのネジ孔状の係合部１０が形成される。なおこの固定体２０は、実施例１のように一対の半割体からなるものではない。実施例２のその他の構造は実施例１と同様である。   As shown in FIG. 14, the fixed body 20 is semi-cylindrical by injection-molding a synthetic resin having weather resistance, and end plates 50 having notched discs are integrally formed at both ends. A notch 51 is formed in 50 so that the branch line 40 can be introduced to the center, and a clamping mechanism 30 similar to that in the first embodiment is provided. The elastic member 31 provided on the surface of the upright wall 32 of the clamping mechanism 30 is provided with a recess 32a so that the branch line 40 is not easily displaced during clamping. In addition, you may form the notch for such a shift prevention in the elastic material 35 of the nail | claw member 34 surface. Then, as shown in FIGS. 15 and 16, a screw hole-like engagement portion 10 for temporary fixing is formed at the bottom of the fixed body 20. The fixed body 20 is not composed of a pair of halves as in the first embodiment. Other structures of the second embodiment are the same as those of the first embodiment.

この蔓巻防止装置は、上記収納部１５ａに固定体２０を収容し、係合孔２８に仮係止手段となる摘子ネジ４１を貫挿し該摘子ネジ４１を係合部１０に螺合することにより、半筒状体１ａと固定体２０とを互いの分離を不能に連結した仮係止状態にて工場から出荷される。   In this anti-wound device, the fixed body 20 is housed in the housing portion 15a, a knob screw 41 serving as a temporary locking means is inserted into the engagement hole 28, and the knob screw 41 is screwed into the engagement portion 10. By doing so, the semi-cylindrical body 1a and the fixed body 20 are shipped from the factory in a temporarily locked state in which separation from each other is impossible.

そしてこの蔓巻防止装置を取付現場にて支線４０に取り付けるに際しては、実施例１で示したように、フック１１ａに支線４０を引っ掛け、該支線４０を切込４６に入れるとともに、摘子部３７に指を掛けて爪部材３４を回転させ、図１６に示されるように、該爪部材３４と起立壁３２とで該支線４０を挟着させる。そして、係合爪５ｂを係合部５ａに係合し、半筒状体１ａと半筒状体１ｂとを閉じることにより、固定体２０を該防止具本体１内に収容した状態にて該固定体２０および防止具本体１が支線４０に取り付けられるようにする。その後、前記摘子ネジ４１を前記係合部１０、係合孔２８から抜脱し、該仮係止手段による固定体２０と防止具本体１との連結状態を解除する。これにより防止具本体１は固定体２０に対して回転自在となり防止具本体１が強風を受けて回転してもその回転トルクが該固定体２０に伝わらない状態としてこの蔓巻防止装置を支線４０に取り付けることができる。   Then, when attaching this device to the branch line 40 at the installation site, as shown in the first embodiment, the branch line 40 is hooked on the hook 11a, the branch line 40 is put into the notch 46, and the knob portion 37 is also inserted. A finger is put on the claw member 34 to rotate it, and the branch line 40 is clamped between the claw member 34 and the standing wall 32 as shown in FIG. Then, the engaging claw 5b is engaged with the engaging portion 5a, and the semi-cylindrical body 1a and the semi-cylindrical body 1b are closed, so that the fixed body 20 is accommodated in the protective device main body 1 in the state of being contained. The fixed body 20 and the prevention tool main body 1 are attached to the branch line 40. Thereafter, the knob screw 41 is removed from the engaging portion 10 and the engaging hole 28, and the connection state between the fixed body 20 and the prevention tool main body 1 by the temporary locking means is released. As a result, the prevention device main body 1 is rotatable with respect to the fixed body 20, and even if the prevention device main body 1 rotates by receiving strong wind, the rotation preventing torque is not transmitted to the fixed body 20 so that the torsion prevention device is connected to the branch line 40. Can be attached to.

この取付方法では、一方の半筒状体１ａにフック１１ａが設けられているとともに、仮係止手段により半筒状体１ａと固定体２０とが予め連結されていることから、該フック１１ａを支線４０に引っ掛けた状態で挟着機構３０を操作する際に固定体２０が分離することなく、一人の作業者によっても二度手間になることなく、簡単かつ迅速に取付を完了することができる。   In this attachment method, the hook 11a is provided on one half-cylindrical body 1a, and the half-cylindrical body 1a and the fixed body 20 are connected in advance by temporary locking means. When the clamping mechanism 30 is operated while being hooked on the branch line 40, the fixing body 20 is not separated, and can be completed easily and quickly without being troubled by a single operator. .

また、こうして取り付けられた蔓巻防止装置は、固定体２０が支線４０にしっかりと固定され、防止具本体１が回転してもその回転トルクが該固定体２０に伝わらないので、固定体２０が回転してずり落ちるようなことがない。また、防止具本体１に固定体２０が内蔵されているので、強風によって該防止具本体１に浮力が掛かっても、該防止具本体１が支線４０に沿って上昇するようなことなく、防止具本体１を常に適切な高さに保持し得る。   Further, in the anti-wound device attached in this way, the fixed body 20 is firmly fixed to the branch line 40, and the rotation torque is not transmitted to the fixed body 20 even when the prevention device main body 1 rotates. There is no such thing as rotating and sliding down. Moreover, since the fixed body 20 is built in the prevention device main body 1, even if buoyancy is applied to the prevention device main body 1 due to strong wind, the prevention device main body 1 is prevented from rising along the branch line 40. The tool body 1 can always be held at an appropriate height.

図１７は実施例２における仮係止手段の他の実施形態を示したもので、この実施形態では結束バンド４３を収納部１５ａの底壁に形成された透孔４４，４５から固定体２０の中心孔中に通すことにより固定体２０と防止具本体１とを仮係止状態にできるようにしている。このように実施例２の場合も仮係止手段として公知の種々の手段を用い得る。   FIG. 17 shows another embodiment of the temporary locking means in Example 2. In this embodiment, the binding band 43 is connected to the fixing body 20 from the through holes 44 and 45 formed in the bottom wall of the storage portion 15a. By passing through the center hole, the fixed body 20 and the prevention tool main body 1 can be temporarily locked. Thus, also in Example 2, various known means can be used as the temporary locking means.

また、図１８は、固定体２０の挟着機構３０の他の実施形態を示したもので、外周縁にリブ３５ａが形成された弾性材３５を爪部材３４に表面に装着し、図１９に示したように支線４０を挟着した際に該リブ３５ａによって支線４０が弾性材３１と弾性材３５との間から抜脱し難くなるように配慮したものである。   FIG. 18 shows another embodiment of the clamping mechanism 30 of the fixed body 20. An elastic material 35 having a rib 35a formed on the outer peripheral edge is attached to the surface of the claw member 34, and FIG. As shown, when the branch line 40 is sandwiched, the rib 35a is considered to make it difficult for the branch line 40 to be pulled out from between the elastic material 31 and the elastic material 35.

また、実施例２で示した固定体２０は、防止具本体１に内蔵したものであるので、内部の挟着機構３０等が悪戯に操作されるおそれがない。このため固定体２０を実施例１のように一対の半割体から構成しなくてもよく、製造コストが軽減されるとともに開閉操作が不要で取付が一層容易になる。なお、固定体２０を防止具本体１に内蔵する場合であっても、図２０に例示したように、該固定体２０を一対の半割体２０ａ，２０ｂから構成してもよいことは勿論である。   In addition, since the fixed body 20 shown in the second embodiment is built in the prevention tool main body 1, there is no possibility that the internal clamping mechanism 30 and the like are misoperated. For this reason, it is not necessary to comprise the fixed body 20 as a pair of halves as in the first embodiment, the manufacturing cost is reduced, and the opening / closing operation is unnecessary, and the attachment is further facilitated. Even when the fixing body 20 is built in the prevention device main body 1, as shown in FIG. 20, the fixing body 20 may be composed of a pair of halves 20a and 20b. is there.

また、実施例１、２に示したフック１１ａは、半筒状体１ａにビス１１ｃにより固着したものであったが、半筒状体１ａと一体成形されていてもよい。また、フックを半筒状体１ａの上部だけでなく中間部や下部にも設け、支線に半筒状体１ａを２箇所以上で引っ掛け、半筒状体１ａが支線とほぼ平行に吊下されるようにしてもよい。   Moreover, although the hook 11a shown in Examples 1 and 2 was fixed to the semi-cylindrical body 1a with the screw 11c, it may be integrally formed with the semi-cylindrical body 1a. Also, hooks are provided not only at the upper part of the semi-cylindrical body 1a but also at the middle part and the lower part. The semi-cylindrical body 1a is hooked on the branch line at two or more places, and the semi-cylindrical body 1a is suspended substantially parallel to the branch line. You may make it do.
