Moreover, FIG. 5 is a photograph (photo at the time of a usage experiment) which shows an example of the usage state of the cover 1 for cable tensioning fasteners.
Note that, hereinafter, the direction that is the longitudinal (axial) direction of the cable 200 in the usage state of the cover 1 for the cable holder 200 will be simply referred to as the "axial direction."

索体引留め金具１００は、図４に示されるように、ワイヤロープ等の索体２００の端末を引留めるために、索体２００の端末部をアイ加工するためのものである。索体引留め金具１００は、くさび形状部分を有する第１の部材１０１と、第１の部材１０１及び索体２００を内部に収める筒状体部を有する第２の部材１０２とを備える。第１の部材１０１のくさび形状部分と、索体２００が、第２の部材１０２の筒状体部に挿通され、第１の部材１０１が打ち込まれる（スライドさせて嵌合される）ことにより、第１の部材のくさび形状に基づいて発生する圧力によって索体２００を拘束するものである。また、索体引留め金具１００は、第１の部材１０１の打ち込み状態を維持するために、第１の部材１０１の後端側を係止する係止ピン１０３を備えている。

The cable tensioning fitting 100 includes a first member 101 having a wedge-shaped portion, and a second member 102 having a cylindrical body portion in which the first member 101 and the cable 200 are housed. The wedge-shaped portion of the first member 101 and the cable body 200 are inserted into the cylindrical portion of the second member 102, and the first member 101 is driven (slided and fitted). The cable body 200 is restrained by pressure generated based on the wedge shape of the first member. Further, the cable tensioning fitting 100 includes a locking pin 103 that locks the rear end side of the first member 101 in order to maintain the driven state of the first member 101.
Note that the cable tensioning fastener 100 is based on the technical idea disclosed in Patent Documents 1 and 2, and its structure and operation are described in each document, so the following description regarding the cable tensioning fastener 100 will be made here. Further explanation will be omitted.

本実施形態の索体引留め金具用カバー１は、図４に示した索体引留め金具１００専用のカバーであり、図１～３に示されるように、
索体引留め金具１００の外側を覆うカバー本体部である、第１側面体１１及び第２側面体１２と、
前記カバー本体部の、索体引留め金具１００が索体２００に取り付けられた状態における索体２００の軸線方向（長手方向）の両端部において、索体２００を挿通させる索体挿通部と、
を備えている。 The cable tensioning fitting cover 1 of this embodiment is a cover dedicated to the cable tensioning fitting 100 shown in FIG. 4, and as shown in FIGS. 1 to 3,
A first side body 11 and a second side body 12, which are cover body parts that cover the outside of the cable tensioning fitting 100;
A cable insertion portion through which the cable body 200 is inserted at both ends of the cover main body in the axial direction (longitudinal direction) of the cable body 200 in a state where the cable cable retaining fitting 100 is attached to the cable body 200;
It is equipped with

カバー本体部は、軸線方向に沿った平面で分割された第１側面体１１及び第２側面体１２によって構成され、これらを相互に接続する接続部であって、第１側面体１１及び第２側面体１２の接合状態と分離状態の間の各側面体の相互の動作（カバーの開閉動作）を許容する接続部１３を備えている。即ち、接続部１３はヒンジ的な機能を有している。
各図からも理解されるように、カバー本体部は、索体引留め金具１００の外径形状に概ね沿った形状を有している。
第１側面体１１の外周には、係止部１１４が４箇所に形成されており、これに対応する形で、第２側面体１２の外周に被係止部１２４が４箇所に形成されている。第１側面体１１と第２側面体１２を接合する（カバーを閉じる）際に、各係止部１１４と被係止部１２４が係合して、両者の接合状態が維持されるものである。 The cover main body is composed of a first side body 11 and a second side body 12 that are divided by a plane along the axial direction, and is a connecting portion that connects these to each other. A connecting portion 13 is provided that allows mutual movement of the side bodies (opening/closing operation of the cover) between the joined state and the separated state of the side bodies 12. That is, the connecting portion 13 has a hinge-like function.
As can be understood from each figure, the cover main body has a shape that generally follows the outer diameter shape of the cable tensioning fitting 100.
Locking parts 114 are formed at four locations on the outer periphery of the first side body 11, and correspondingly, locked parts 124 are formed at four locations on the outer periphery of the second side body 12. There is. When joining the first side body 11 and the second side body 12 (closing the cover), the respective locking portions 114 and the locked portions 124 are engaged to maintain the joined state between the two. .

カバー本体部の軸線方向の両端部に形成される索体挿通部は、図４，５からも理解されるように、索体引留め金具１００の使用時において、索体引留め金具１００の軸線方向の両端から出ている索体２００を通すためのものである。
索体引留め金具１００は、所定の範囲の径の索体に対して利用可能なものであり、また、取り付け状態において索体の位置が変わり得る（個別の取り付け状態に基づいて変化し得る）ものである。従って、索体引留め金具用カバー１の索体挿通部は、これらの索体の径の違いや位置の違いを吸収しつつ、なるべく隙間が生じないようにカバーできるものであることが好ましく、索体と弾性的に接触する弾性接触部として形成されることが好ましい。
本実施形態では、弾性接触部として、櫛歯状の部材である櫛歯部１１１ａ、１１１ｂ、１２１ａ、１２１ｂを備えている。第１側面体１１の軸線方向の両端に弾性的に変形可能な櫛歯部１１１ａと１１１ｂがそれぞれ形成され、第２側面体１２の軸線方向の両端に弾性的に変形可能な櫛歯部１２１ａと１２１ｂがそれぞれ形成されている。
各櫛歯部１１１ａ、１１１ｂ、１２１ａ、１２１ｂの、各歯（若しくは毛）は、それぞれ軸線方向の外側へと向かう方向成分をもって延在している。同時に、第１側面体１１と第２側面体１２の接合面から離れた位置から、接合面へと向かう方向成分（第１側面体１１の各歯（若しくは毛）は、図２（ｄ）において上方へ向かう方向成分、第２側面体１２の各歯（若しくは毛）は、図２（ｅ）において下方へ向かう方向成分）をもって延在し、接合面を超える位置まで（第１側面体１１の各歯（若しくは毛）は、図２（ｄ）において接合面より上側まで、第２側面体１２の各歯（若しくは毛）は、図２（ｅ）において接合面より下側まで）延在している。
当該構成により、第１側面体１１と第２側面体１２を接合した（カバーを閉じた）際には、櫛歯部１１１ａと櫛歯部１２１ａの各歯（若しくは毛）が相互に弾性的に変形しながら接触し、同様に、櫛歯部１１１ｂと櫛歯部１２１ｂの各歯（若しくは毛）が相互に弾性的に変形しながら接触する。弾性接触部が櫛歯状に形成されていることにより、索体２００が通る箇所の歯（若しくは毛）のみ、索体２００が通るように弾性的に変形することが可能であるため、索体の径の違いや位置の違いを吸収しつつ、なるべく隙間が生じないようにカバーすることができる。当該作用の観点からは、各歯（若しくは毛）の間の隙間はなるべく小さい（無い）方が好ましく、また、各歯（若しくは毛）もなるべく細い方が好ましいと言える。ただし、各歯（若しくは毛）をあまり細くし過ぎると、“コシ”（弾性力）が無くなり、索体との密着力（隙間を低減する力）が低下する場合もあるため、各歯（若しくは毛）の太さは、使用する材料などとの関係も考慮して適宜定めるようにするとよい。
なお、図５の写真からも一部見て取れるように、櫛歯部１１１ａ（１１１ｂ）と櫛歯部１２１ａ（１２１ｂ）の各歯（若しくは毛）は、図３で示したように相互に接触して合掌したような構成となるものに限らず、各歯（若しくは毛）が互いに各歯の隙間に入り込むようにクロスした状態となる形態もある。 As can be understood from FIGS. 4 and 5, the cable insertion portions formed at both ends of the cover main body in the axial direction are connected to the axis of the cable tensioning fitting 100 when the cable tensioning fitting 100 is used. This is for passing the cables 200 coming out from both ends of the direction.
The rigging fastener 100 is available for rigging of a predetermined range of diameters, and the position of the rigging can change in the attached condition (which can change based on the particular attached condition). It is something. Therefore, it is preferable that the cable insertion part of the cover 1 for the cable suspension fitting is capable of absorbing differences in the diameter and position of these cables, and can cover the cables with as few gaps as possible. Preferably, it is formed as an elastic contact portion that elastically contacts the cord.
In this embodiment, comb-teeth portions 111a, 111b, 121a, and 121b, which are comb-teeth-shaped members, are provided as the elastic contact portions. Elastically deformable comb teeth portions 111a and 111b are formed at both ends of the first side body 11 in the axial direction, and elastically deformable comb teeth portions 121a and 111b are formed at both ends of the second side body 12 in the axial direction. 121b are formed respectively.
Each tooth (or hair) of each comb tooth portion 111a, 111b, 121a, 121b extends with a direction component toward the outside in the axial direction. At the same time, the direction component (each tooth (or hair) of the first side body 11 from a position away from the joint surface of the first side body 11 and the second side body 12 toward the joint surface is Each tooth (or hair) of the second side body 12 extends with an upward direction component and a downward direction component in FIG. Each tooth (or hair) extends above the joint surface in FIG. 2(d), and each tooth (or hair) of the second side body 12 extends below the joint surface in FIG. 2(e). ing.
With this configuration, when the first side body 11 and the second side body 12 are joined (the cover is closed), the teeth (or bristles) of the comb tooth portion 111a and the comb tooth portion 121a elastically interact with each other. Similarly, the teeth (or bristles) of the comb tooth portion 111b and the comb tooth portion 121b contact each other while being elastically deformed. Since the elastic contact portion is formed in a comb-teeth shape, only the teeth (or hairs) where the cable body 200 passes can be elastically deformed so that the cable body 200 passes through. While absorbing differences in diameter and position, it is possible to cover with as few gaps as possible. From the viewpoint of the effect, it is preferable that the gap between the teeth (or bristles) be as small as possible (no gap), and it is also preferable that each tooth (or bristles) be as thin as possible. However, if each tooth (or hair) is made too thin, it will lose its "elasticity" and the adhesion force (force to reduce gaps) with the cable may decrease. The thickness of the bristles should be determined as appropriate, taking into consideration the relationship with the materials used.
In addition, as can be partially seen from the photograph in FIG. 5, the teeth (or bristles) of the comb tooth portion 111a (111b) and the comb tooth portion 121a (121b) are in contact with each other as shown in FIG. It is not limited to a configuration where the palms are joined together, but there is also a configuration where the teeth (or hairs) are crossed so that they fit into the gaps between the teeth.

第１側面体１１と第２側面体１２には、それぞれ、カバー本体部の外周を巻き回される結束部材（結束バンド等）を案内するガイド部１１２、１２２を備える。カバーを閉じた状態（図３の状態）において、補強的に索体引留め金具用カバー１を結束部材（結束バンド等）で縛る際に、結束部材（結束バンド等）のズレ防止等の作用を有するものである。なお、本実施形態では、ガイド部１１２、１２２が索体引留め金具用カバー１の一方側（図３の下側）にのみ設けられているが、ガイド部を適宜複数設けるものであっても勿論よい（本実施形態の場合においても、２本の接続部１３の間に結束部材を配することで、接続部１３がガイド部としても機能し得るため、ガイド部が上下２か所に設けられていると言える）。なお、係止部１１４と被係止部１２４の係合等によって、十分か係合力が得られる場合には、結束部材やこれを案内するガイド部は必ずしも必要ない。 The first side body 11 and the second side body 12 are respectively provided with guide portions 112 and 122 that guide a binding member (such as a binding band) wound around the outer periphery of the cover main body. In the closed state of the cover (the state shown in Fig. 3), when the cover 1 for the cable pulling fastener is tied up with a binding member (such as a binding band) for reinforcement, the function of preventing the binding member (such as a binding band) from slipping. It has the following. In addition, in this embodiment, the guide parts 112 and 122 are provided only on one side (lower side in FIG. 3) of the cover 1 for the cable tensioning fitting, but a plurality of guide parts may be provided as appropriate. Of course, this is fine (also in the case of this embodiment, by disposing the binding member between the two connecting parts 13, the connecting part 13 can also function as a guide part, so it is not necessary to provide the guide parts in two places, upper and lower). ). Note that if a sufficient engagement force is obtained by the engagement between the locking portion 114 and the locked portion 124, the binding member and the guide portion for guiding the binding member are not necessarily required.

第１側面体１１と第２側面体１２にそれぞれ形成されている膨出部１１３、１２３は、索体引留め金具１００の係止ピン１０３に干渉しないように内部スペースを形成しているものである。係止ピンを用いない索体引留め金具のような場合には、必ずしも必要が無いものである。 The bulges 113 and 123 formed on the first side body 11 and the second side body 12 respectively form an internal space so as not to interfere with the locking pin 103 of the cable tensioning fitting 100. be. This is not necessarily necessary in the case of a cable tensioning fitting that does not use a locking pin.

索体引留め金具用カバー１の取り付け作業は、上記説明した構成及び図４，５等からも容易に理解されるように、索体２００に取り付けられた索体引留め金具１００（図４）に対し、開いた状態の索体引留め金具用カバー１の第１側面体１１若しくは第２側面体１２の一方をあてがうように配置し、他方を、接続部１３をヒンジ的に曲げることでカバーを閉じるように動作させ、各係止部１１４と各被係止部１２４を係合させることで行われる。
この際に、櫛歯部１１１ａと櫛歯部１２１ａ及び櫛歯部１１１ｂと櫛歯部１２１ｂのそれぞれが、両端部から飛び出る索体２００に対して、その周りを覆うように、且つ、隙間が低減されるように付勢されて、索体２００と係合するような構成となる。
なお、より密閉度を高めるために、櫛歯部（索体挿通部）の部分にコーキング加工をするようにしてもよい。 As can be easily understood from the above-described configuration and FIGS. 4, 5, etc., the work of attaching the cover 1 for the cable tensioning fitting is performed by attaching the cable tensioning fitting 100 (FIG. 4) attached to the cable 200. , one of the first side body 11 and the second side body 12 of the cover 1 for the cable tensioning fitting in the open state is placed so as to be applied, and the other side is covered by bending the connecting portion 13 like a hinge. This is done by closing the locking portions 114 and engaging the locked portions 124.
At this time, each of the comb-teeth portion 111a and the comb-teeth portion 121a and the comb-teeth portion 111b and the comb-teeth portion 121b are arranged so as to cover the circumference of the cable body 200 protruding from both ends, and to reduce the gap. The structure is such that it is biased so as to engage with the cable body 200.
In addition, in order to further improve the degree of sealing, caulking may be applied to the comb tooth portion (cord insertion portion).

以上のごとく、本実施形態の索体引留め金具用カバー１によれば、索体を引留めるために使用される索体引留め金具において、これをカバーすることで、融雪剤（塩）等の索体引留め金具への接触が低減され、その耐食性、耐久性を向上させることができる。
本実施形態の索体引留め金具用カバー１は、上記から理解されるように、その取り付け作業が簡便であり、作業効率の面でも優れている。 As described above, according to the cover 1 for cable tensioning fasteners of the present embodiment, by covering the cable tensioning metal fittings used for fastening the cables, snow melting agent (salt), etc. Contact with the cable tensioning fasteners is reduced, and its corrosion resistance and durability can be improved.
As understood from the above, the cover 1 for the cable tensioning fastener according to the present embodiment is easy to install and has excellent work efficiency.

なお、本実施形態では、カバー本体部の形状が、図４に示した索体引留め金具１００の外形形状に概ね沿った形状で形成されることで、図４に示した索体引留め金具１００の専用のケースであるものを例としているが、本発明をこれに限るものではない。上記説明した概念に沿って、適宜カバー本体部の形状を各索体引留め金具の形状に合わせて変更することで、各索体引留め金具に対して本発明を利用することができる。また、カバー本体部は、個別の索体引留め金具の外形形状に概ね沿った形状とすることを必須とするものではなく、汎用的な形状とすることで、複数の索体引留め金具に対して利用可能なものとしてもよい。 In addition, in this embodiment, the shape of the cover main body portion is formed in a shape that roughly follows the outer shape of the rope suspension fitting 100 shown in FIG. Although 100 dedicated cases are taken as an example, the present invention is not limited thereto. In accordance with the above-described concept, the present invention can be applied to each rope tensioning fitting by appropriately changing the shape of the cover main body portion to match the shape of each rope tensioning fitting. In addition, the cover main body part does not necessarily have to have a shape that roughly follows the external shape of each individual cable tensioning fastener, but can be made into a general-purpose shape so that it can be used with multiple cable tensioning fasteners. It may also be available for use.

本実施形態では、カバー本体部が２つの側面体によって形成されるものを例としたが、本発明をこれに限るものではなく、カバー本体部が３つ以上の部材によって構成されるものであってもよい。
また、本実施形態では、２つの側面体が接続部によって接続されているものを例としたが、カバー本体部を構成する部材が相互に接続されていないもの（例えばバラバラの部品を組み立てるもの等）であっても構わない。
接続部は各部材を、カバー開状態と閉状態の間で保持できる任意の形状としてよい。図６（ａ）には、接続部の別の形状の一例（接続部１３´）を示した。 In this embodiment, the cover main body is formed of two side bodies, but the present invention is not limited to this, and the cover main body may be formed of three or more members. You can.
In addition, in this embodiment, the two side bodies are connected by a connecting part, but the cover main body is not connected to each other (for example, when assembled from separate parts, etc.). ).
The connecting portion may have any shape capable of holding each member between the cover open state and the closed state. FIG. 6A shows an example of another shape of the connecting portion (connecting portion 13').

本実施形態では、索体挿通部としての櫛歯部が、カバー本体部の軸線方向の両端部側面において全体的に設けられているものを例としたが、本発明をこれに限るものではなく、索体挿通部が部分的に設けられるもの等であってもよい。図６（ｂ）には、そのようなものの一例を示した。図６（ｂ）の例では、櫛歯部１１１ｂ´と櫛歯部１２１ｂ´が、上部側半分程度にのみ形成されている。図４、５からも理解されるように、索体引留め金具１００では、アイ加工側の側面では、索体２００が上端及び下端に存在する傾向となるのに対し、反対側の側面では、索体２００が上部側にしか存在しない傾向となるため、索体２００の存在する位置に合わせて、櫛歯部１１１ｂ´と櫛歯部１２１ｂ´が上部側半分程度にのみ形成されているものである。このように、各索体引留め金具の構成に合わせて、索体が存在し得る範囲にのみ索体挿通部を形成するようにしてもよい（例えば、索体が軸線方向の一方側からのみ出るような場合には、索体挿通部を軸線方向の一方側のみに設けるようにしてもよい）。 In the present embodiment, the comb tooth portions serving as the cable insertion portions are provided entirely on the side surfaces of both ends in the axial direction of the cover main body portion, but the present invention is not limited to this. , the cable insertion portion may be partially provided. FIG. 6(b) shows an example of such a device. In the example of FIG. 6(b), the comb tooth portion 111b' and the comb tooth portion 121b' are formed only in about half of the upper side. As can be understood from FIGS. 4 and 5, in the cable tensioning fitting 100, on the eye-processed side, the cables 200 tend to exist at the upper and lower ends, whereas on the opposite side, Since the cable body 200 tends to exist only on the upper side, the comb tooth portion 111b' and the comb tooth portion 121b' are formed only in about half of the upper side in accordance with the position where the cable body 200 is present. be. In this way, depending on the configuration of each cable anchorage fitting, the cable insertion portion may be formed only in the range where the cable can exist (for example, if the cable can be inserted only from one side in the axial direction). In such a case, the cord insertion portion may be provided only on one side in the axial direction).

本実施形態では、索体挿通部としての櫛歯部が、カバー本体部（側面体）と一体的に形成されるものを例としているが、本発明をこれに限るものではなく、櫛歯部がカバー本体部とは別体で形成されて、カバー本体部と組み合わされる（接着など）ものであってもよい。
また、複数の櫛歯部を重ね合わせるようにしてもよい。櫛歯部の歯（若しくは毛）の間の隙間をカバーするように、複数の櫛歯部においてその歯（若しくは毛）の位置が互い違いとなるように、櫛歯部を重ね合わせるようにすると、隙間をより低減したケースとし得る。
本実施形態では、櫛歯部の歯（若しくは毛）が、それぞれ軸線方向の外側へと向かう方向成分をもって延在しているものを例としているが、本発明をこれに限るものではなく、櫛歯部の歯（若しくは毛）が、軸線方向の内側へと向かう方向成分をもって延在しているものであってもよい。即ち、本実施形態では、カバー本体部の両側面から外側へと向かうように歯（若しくは毛）が形成されているが、カバー本体部の内部へと向かうように歯（若しくは毛）が形成されるものであっても構わない。或いは、側面体の接合面へと向かう成分のみを持った方向に歯（若しくは毛）が形成されているものであってもよい。
また、本実施形態では、櫛歯部の歯（若しくは毛）が、２つの側面体の両方に形成されているものを例としたが、本発明をこれに限るものではなく、例えば、２つの側面体のいずれか一方にのみ櫛歯部の歯（若しくは毛）が形成されているようなものであってもよい。例えば、本実施形態における第１側面体１１の櫛歯部１１１ａを単なる板状の部材とし、これ対して第２側面体１２の櫛歯部１２１ａが当接し、第２側面体１２の櫛歯部１２１ｂが単なる板状の部材で、これ対して第１側面体１１の櫛歯部１１１ｂが当接するような構成であってもよい。 In this embodiment, the comb-teeth portion as the cable insertion portion is formed integrally with the cover main body (side body), but the present invention is not limited to this, and the comb-teeth portion may be formed separately from the cover body and combined with the cover body (by adhesion, etc.).
Further, a plurality of comb teeth portions may be overlapped. When the comb teeth are overlapped so that the positions of the teeth (or bristles) are alternated in a plurality of comb teeth so as to cover the gaps between the teeth (or bristles) of the comb teeth, A case may be made in which the gap is further reduced.
In this embodiment, an example is given in which the teeth (or bristles) of the comb tooth portion each extend with a direction component toward the outside in the axial direction, but the present invention is not limited to this. The teeth (or bristles) of the tooth portion may extend with a direction component directed inward in the axial direction. That is, in this embodiment, the teeth (or bristles) are formed so as to go outward from both side surfaces of the cover body, but the teeth (or bristles) are formed so as to go inside the cover body. It doesn't matter if it is Alternatively, the teeth (or bristles) may be formed in a direction with only a component toward the joint surface of the side body.
Further, in this embodiment, the teeth (or bristles) of the comb tooth portion are formed on both of the two side bodies, but the present invention is not limited to this. The comb teeth (or bristles) may be formed only on one side of the side body. For example, the comb-teeth portion 111a of the first side body 11 in this embodiment is a simple plate-like member, and the comb-teeth portion 121a of the second side body 12 is in contact with the comb-teeth portion 111a of the second side body 12. 121b may be a simple plate-shaped member, and the comb tooth portion 111b of the first side body 11 may be in contact with this member.
