【考案の詳細な説明】
この考案は、玉掛は作業用吊りひも等として用いられる
エンドレススリングに関するものである。[Detailed description of the invention] This invention relates to an endless sling used as a hanging cord for work.
従来、第１図に示すような、抗張力の大きい糸を何重に
も巻回してつくった無端状の芯材１を耐摩耗性に富んだ
柔軟な布からなる筒状の袋体２で包み、筒状の袋の両端
を重ね合わせて縫着したエンドレススリング（第２図）
３が玉掛は作業用吊りひも等として用いられている。Conventionally, as shown in Fig. 1, an endless core material 1 made by winding a yarn with high tensile strength many times is wrapped in a cylindrical bag body 2 made of a flexible cloth with high wear resistance. , an endless sling made by overlapping and sewing the ends of a cylindrical bag (Figure 2)
3. The sling is used as a hanging cord for work.
第２図において、３ａは袋体端部の縫着部である。In FIG. 2, 3a is a sewn portion at the end of the bag.
この種のエンドレススリングは、全体が柔軟であるため
被吊下物体の形状になじみやすく安定した吊下状態を得
ることができる。This type of endless sling is flexible as a whole, so it easily adapts to the shape of the suspended object and provides a stable suspended state.
しかしながら、エンドレススリングを長円状にして長円
の一端を他端内に通し第３図のようにその一端をフック
４に係止し、生皮した輪のなかに被吊下物体５を入れて
吊り下げる（チョーク吊り）場合は、被吊下物体５の重
量によって第４図に示すようにエンドレススリングの他
端６が一端７側を矢印のように滑り下りるため、一端７
側の袋部分がいわばしごかれた状態となり、破れやすか
った。However, if the endless sling is made into an oval shape, one end of the oval is passed through the other end, and one end is secured to the hook 4 as shown in FIG. 3, and the suspended object 5 is placed inside the rawhide ring. When hanging (choke hanging), the weight of the suspended object 5 causes the other end 6 of the endless sling to slide down the end 7 side as shown by the arrow, as shown in FIG.
The bag on the side was so squeezed that it was easy to tear.
特に一端７側に縫着部３ａが存在するとその部分から破
れが生じやすかった。In particular, if the sewn portion 3a was present on the one end 7 side, tearing was likely to occur from that portion.
この考案は、このような事情に鑑みなされたもので、全
部もしくは接合個所となる両端を除く部分が縦糸群から
なる無端状の芯材を柔軟な素材からなる筒状の袋体で包
んでなるエンドレススリングであって、筒状の袋体の長
手方向に沿う全周にわたってもしくは部分的に縦糸多数
と接触するよう芯村内を貫通する縫い目が入られて筒状
の袋体と芯材とが弱く結合されていることを特徴とする
エンドレススリングをその要旨とするものである。This idea was devised in view of the above circumstances, and consists of an endless core material whose whole or parts except for the two ends where they are joined are made up of a group of warp threads, and wrapped in a cylindrical bag made of a flexible material. It is an endless sling, and the cylindrical bag and the core material are weak because a seam is inserted through the core so as to contact the entire circumference along the length of the cylindrical bag or partially with a large number of warp threads. The gist of this is an endless sling that is characterized by being connected.
すなわち、上記のように袋体に芯材の縦糸多数と接触す
るよう縫い目を入れて縫い目部分が芯村内を貫通するよ
うにすることにより、袋体と芯材とを弱く結合させ、チ
ョーク吊りの際に、袋の一部をしごくような力が加えら
れてもその部分が芯材によって保持されるようになるた
め、力の向う方向に移動しなくなる。In other words, as mentioned above, by inserting seams in the bag body so that they come into contact with many of the warp threads of the core material, and making the seam portion penetrate through the inside of the core material, the bag body and the core material are weakly bonded, and the chalk hanging is made easier. Even if a force is applied to a part of the bag, that part will be held by the core material and will not move in the direction of the force.
したがって袋の破れが生じなくなる。Therefore, the bag will not be torn.
この縫目によってスリングの腰が強くなり、却って使い
やすくもなる。This seam makes the sling stronger and makes it easier to use.
第５図はその一実施例を示すもので、無継目筒状の袋体
８の長手方向に沿って２本の縫い目９が平行に、かつ袋
体８の全長にわたって芯材１０の縦糸多数と接触するよ
う設けられ、その縫い目部分では、芯材１０内を貫通す
る縫い糸９ａにより袋体８と芯材１０とが弱く結合一体
化されている。FIG. 5 shows an example of this, in which two seams 9 are parallel to each other along the longitudinal direction of a seamless cylindrical bag 8, and a large number of warp threads of a core material 10 extend along the entire length of the bag 8. The bag body 8 and the core material 10 are weakly connected and integrated at the seam portion, which is provided so as to be in contact with each other, by the sewing thread 9a passing through the interior of the core material 10.
第６図は他の実施例を示すもので、筒状の袋体１１、帯
状の布材をその長手方向に沿う両側縁１１ａ、ｌｌｂを
重ね合わせて合わせ目を縫うことにより継目布状に構成
されており、その縫い糸１２ａにより縫い目１２が袋体
１１の長手方向に沿いかつ全長にわたって芯材１３の縦
糸多数と接触するよう設けられている。FIG. 6 shows another embodiment, in which a cylindrical bag 11 and a strip-like cloth material are constructed into a seamed cloth-like structure by overlapping both edges 11a and llb along the longitudinal direction and sewing the seams. The seam 12 is provided along the longitudinal direction of the bag body 11 and in contact with a large number of warp threads of the core material 13 over the entire length by the sewing thread 12a.
この実施例では、縫い目１２の縫い糸１２ａが筒状袋体
１１の構成作用と袋体１１・芯材１３の一体化作用とを
発揮している。In this embodiment, the sewing thread 12a of the seam 12 functions to construct the cylindrical bag 11 and to integrate the bag 11 and the core material 13.
第７図はさらに他の実施例を示すもので、筒状の袋体１
４が、帯状の布材をその長手方向に沿う両側縁を縫着し
て表裏を反転させることにより継目布状に構成されてお
り、筒状袋体１４の長手方向に沿って縫い目１５が袋体
１４の全長にわたって芯材１６の縦糸多数と接触するよ
う設けられている。FIG. 7 shows still another embodiment, in which the cylindrical bag body 1
4 is constructed in the form of a seamed cloth by sewing the longitudinal edges of a strip of cloth material and turning the front and back sides of the material. It is provided so as to be in contact with many warps of the core material 16 over the entire length of the body 14.
１６は芯材、１７は帯状の両側縁の縫い合わせ部である
。Reference numeral 16 indicates a core material, and reference numeral 17 indicates a seam portion on both side edges of the band.
なお、上記実施例は、縫い目を２本人れているが、１本
でもよく、３本以上でもよい。In the above embodiment, there are two stitches, but there may be one or three or more stitches.
また、袋体の全長にわたって入れるのではなく部分的に
入れるようにしてもよい。Further, instead of being inserted over the entire length of the bag, it may be inserted partially.
また、第１図に示す芯材１に代えて、両端２０．２１が
織組織化され、それ以外の部分２２が長さ方向を揃えた
縦糸の束からなる素材の両端組織部分を重ね合わせて縫
製加工２３した芯材１９を用いてもよい。In addition, instead of the core material 1 shown in FIG. 1, both ends 20 and 21 of the material are woven, and the other parts 22 are made of bundles of warp threads aligned in the length direction. A core material 19 that has been sewn 23 may be used.
この考案のエンドレススリングは、上記のように、筒状
の袋体の長手方向に沿う全周にわたってもしくは部分的

れられ、縫い目部分で芯材と袋体とが弱く一体化されて
いるため、チョーク吊り等の際に袋体がしごかれたよう
な状態にならず、したがって袋体の破れが生じないので
ある。As mentioned above, the endless sling of this invention has a seam that penetrates the core so that it contacts the entire circumference along the length of the cylindrical bag or a number of warp threads partially, and the core material at the seam part. Since the bag body and the bag body are weakly integrated, the bag body does not become strained when hanging chalk, etc., and therefore the bag body does not tear.
縫目によりスリングの腰の強さが調整され、使い易くも
なっている。The seams adjust the strength of the sling's waist, making it easier to use.
