Description
【０００１】[0001]
本考案は、支線に沿わせてケーブルの延線作業を行う際、支線に移動自在に吊 架して用いるケーブル延線用具に関するものである。 The present invention relates to a cable extension tool that is movably suspended on a branch line when the cable is extended along the branch line.
【０００２】[0002]
用具主体に吊線に沿って転動する支車と、ケーブルに接して回動する一対のロ ーラーを備えた構造の移動金車（第一従来例）と称するものがある。 BACKGROUND ART There is a so-called movable metal wagon (first conventional example) having a structure in which a tool is mainly used to roll along a suspension line and a pair of rollers are rotated in contact with a cable.
【０００３】 移動金車はケーブル延線用具としてそれなりに機能するものであるが、全体が 金属製であるため重量が嵩み、取扱い上の不便さがあるだけでなく、構造上、吊 線に組付ける際の作業性が悪い欠点がある。A mobile wagon functions as a cable-drawing tool as it is, but since it is made of metal as a whole, it is heavy and inconvenient to handle. There is a drawback that workability when assembling is poor.
【０００４】 この移動金車、殊に重量の嵩む欠点を回避するものとして、金属杆をなす環状 に屈曲して用具主体を構成し、該用具主体のなす環形状の一側を開放できるよう にする一方、用具主体の上円弧部には支線に接して回動するリング体を、下円弧 部にはケーブルに接して回動するリング体を組付けた構造のもの（第二従来例） がある。As a means for avoiding the disadvantage of being heavy in weight, in particular, this moving gold wheel is configured so that a tool main body is formed by bending it into an annular shape that forms a metal rod, and one side of the ring shape formed by the tool main body can be opened. On the other hand, there is a structure in which a ring body that rotates in contact with a branch line is attached to the upper arc portion of the tool main body, and a ring body that rotates in contact with the cable is attached to the lower arc portion (second conventional example). is there.
【０００５】[0005]
第二従来例は、用具主体を金属杆を屈曲して構成したことおよびリング体を樹 脂製にしたことによって、第一従来例の重量の嵩む欠点を解決したものではある が、なす環形状内に吊線を挿入したり、或いは延線作業後に、なす環形状内より ケーブルを外す際、用具主体を構成する金属杆の弾性を利用して、用具主体のな す環形状の一側を開放しなければならない。 The second conventional example solves the heavy weight defect of the first conventional example by forming the tool main body by bending a metal rod and by making the ring body made of resin. When inserting the suspension wire into the cable or removing the cable from the ring shape after wire drawing, use the elasticity of the metal rod that constitutes the tool body to open one side of the tool body. Must.
【０００６】 すなわち、用具主体にはリング体を介してケーブルの重量が負荷されるため相 応の剛性有る金属杆で構成する必要が有り、そのため、弾性を利用してなす環形 状の一側を開放するといっても、その作業が煩雑とならざるを得ない。That is, since the weight of the cable is mainly loaded on the tool body through the ring body, it is necessary to configure the metal rod with a corresponding rigidity. Therefore, one side of the ring shape formed by utilizing elasticity is used. Even if it is opened, the work must be complicated.
【０００７】 また、第二従来例は用具主体を構成する金属杆を貫通させるようにして樹脂製 のリング体を用具主体に組付けてあるため、該リング体に吊線ないしケーブルが 接しても必ずしも円滑に回動しない場合がある。Further, in the second conventional example, since the resin-made ring body is attached to the tool main body so as to penetrate the metal rod that constitutes the tool main body, even if the suspension wire or the cable comes into contact with the ring body, it is not always necessary. It may not rotate smoothly.
【０００８】 本考案は斯様な点に着目して案出したものである。The present invention has been made in view of such a point.
【０００９】[0009]
