【考案の詳細な説明】 ［産業上の利用分野］ 本考案は重量物を貯蔵する場合には、他の堅い物体と接
触することによる表面の傷付きを防止する梱包用緩衝材
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cushioning material for packing which prevents damage to the surface due to contact with other hard objects when storing heavy objects.

［考案の背景］ 重量物の貯蔵を例えば表面を特殊塗装した輸出用大径鋼
管について説明する。これらの鋼管は製造後出荷時期が
来るまで一応貯蔵場に積み上げて保管される。鋼管は水
平にちどり形に積み上げられるが、各鋼管が隣接の鋼管

品価値が大巾に低下することになる。[Background of the Invention] Storage of heavy goods will be described, for example, for a large-diameter steel pipe for export whose surface is specially coated. These steel pipes are once piled up and stored in the storage area until the time of shipment after manufacturing. Steel pipes are piled up horizontally in a striped shape, but if each steel pipe is in direct contact with the adjacent steel pipes, it is a heavy weight, so it is hard to hit, the surface of the steel pipe is scratched, and the special coating is also peeled off. The product value will drop significantly.

そのため従来は貯蔵する鋼管の２ケ所以上に断面矩形の
ゴム帯を１回巻きし、両端の穴に別の細い連結用ロープ
を通して結び合わせて鋼管に取り付け、積み上げ時は隣
接鋼管との間に挾むことにより、緩衝材として鋼管の表
面を保護していた。Therefore, in the past, a rubber band with a rectangular cross section was wound once around two or more places of the steel pipe to be stored, and it was attached to the steel pipe by tying it through another thin connecting rope through the holes at both ends, and when it was stacked, it was inserted between adjacent steel pipes. Thus, the surface of the steel pipe was protected as a cushioning material.

しかし下積みの鋼管は上積みの鋼管が増す毎に更に下方
に押し下げられるが、ゴム帯は鋼管との摩擦が大きいの
で滑り動くことが出来ず、隣接部の表裏に生じた摩擦力
によって長期間には永久的伸びを作り、積み替え時には
役に立たなくなる。又上記の力により連結用ロープが切
断することもある。However, the lower stacked steel pipes are pushed down further each time the upper stacked steel pipes increase, but the rubber band cannot slide due to the large friction with the steel pipes, and due to the frictional force generated on the front and back of the adjacent part, it will not be possible for a long time. Creates permanent growth and becomes useless when transshipping. Also, the above-mentioned force may break the connecting rope.

ゴム帯自体については、非常に重く一人で一本を辛うじ
て運搬できる程度であり、従って作業性は極めて低い。
製作には時間が掛り急場に間に合わず、且つ高価であ
る。又加工性が悪く、僅か長すぎても切断が困難であ
り、連結用ロープを通す穴を開けることは不可能であ
る。The rubber band itself is very heavy and can barely be carried by one person alone, and therefore the workability is extremely low.
Manufacturing is time consuming, too late to be in the emergency, and expensive. Further, the workability is poor, and even if the length is too long, it is difficult to cut it, and it is impossible to make a hole for passing the connecting rope.

又ゴム帯は巻いても自力で直線に伸びるため、貯蔵には
広い面積を必要とし貯蔵費がかさむ欠点もある。Further, since the rubber band stretches in a straight line by itself even when wound, it has a drawback that it requires a large area for storage and the storage cost is high.

［考案が解決しようとする問題点］ ゴム帯は上記の如く多数の問題点を持っているので、本
考案では軽くて作業性がよく、かさばらず、安価で、切

ない重量物に対する梱包用緩衝材を提供する事を目的と
する。[Problems to be solved by the device] Since the rubber band has a number of problems as described above, the present invention is light and easy to work with, is not bulky, is inexpensive, can be freely cut and stretched. An object of the present invention is to provide a cushioning material for packing heavy objects whose connecting portion is not cut.

したものを使用する。[Means for Solving the Problems] In the present invention, a single outer yarn (yarn) made of plastic fibers, for example, polypropylene fibers is further twisted to form a composite yarn (strand), which is formed by combining a large number of the yarns for a hollow outer portion. Use a braided rope with a large number of string-shaped plastic or synthetic fibers to prevent flattening of the braid and a rope for connecting both ends.

クあるいは合成繊維６が配置されている。In FIG. 1 and FIG. 2 which is an enlarged view thereof, 1 is a single composite yarn, 2 is a composite yarn, and 3 is a fiber. In the sectional view of FIG. 3, reference numeral 5 is a synthetic fiber connecting rope, and a large number of string-shaped plastics or synthetic fibers 6 are arranged between the outer rope 4 and the outer braid structure rope 4 to prevent flattening.

中空組紐を作って連結用ロープ５を通した物を、外側用
組紐構造ロープ４の中を貫通させたものでもよい。As the string-shaped plastic, a film tape may simply be twisted, but in order to further prevent flattening,
A hollow braid made of a hard plastic fiber such as an olefin fiber and made to pass through the connecting rope 5 may pass through the outside braid structure rope 4.

［作用］ 上記の組紐構造は引っ張れば長くて細くなり、太くすれ

目の締まり方により起こっているものである。伸縮性は
作業上有利であるが細過ぎては梱包上困るので、本考案
においては多数の紐形材料を挿入して組紐構造の縮小と
偏平化を防止している。[Operation] The above-mentioned braided structure becomes long and thin when pulled, and becomes short when thickened, but this is caused by the tightening of the knitting rather than the expansion and contraction of the fiber. Stretchability is advantageous for work, but too thin is difficult for packaging. Therefore, in the present invention, a large number of cord-shaped materials are inserted to prevent the braid structure from being reduced and flattened.

又組紐構造の表面に出ている各複合糸の撚り糸の繊維は
ロープの長さ方向に略平行に並んでいることと、プラス
チックあるいは合成繊維固有の表面性能とが相俟って滑
りがよく、摩擦係数は極めて小さい。Also, the fibers of the twisted yarns of the respective composite yarns appearing on the surface of the braided structure are arranged substantially parallel to the length direction of the rope, and the surface performance peculiar to the plastic or synthetic fiber is combined, and the slip is good, The coefficient of friction is extremely small.

更に上記ロープの内部を構成する物の材質も、全て又は
殆どがプラスチックあるいは合成繊維であるため、表面
の滑りがよく摩擦係数は小さい。従って組紐構造は伸び
縮みする事などによって、これを挾む重量物に多少の移
動があっても、何等無理する部分がなく、永久的変形も
連結用ロープの切断も起こらない。Furthermore, since all or most of the material constituting the inside of the rope is plastic or synthetic fiber, the surface is slippery and the coefficient of friction is small. Therefore, if the braided structure expands and contracts, and there is some movement of the heavy object that sandwiches the braided structure, there will be no unreasonable portion, and permanent deformation and disconnection of the connecting rope will not occur.

［考案の効果］ 本考案による梱包用緩衝材は従来の同長のゴム帯に比較
して極めて軽く10％以下に過ぎない。又形状の変化に対
して殆ど抵抗がないので作業性は極めてよく、短く折っ
て積み上げれば小面積に多量を収納することで貯蔵性も
非常によい。[Effect of the Invention] The cushioning material for packaging according to the present invention is extremely lighter than the conventional rubber band of the same length and is less than 10%. In addition, since there is almost no resistance to changes in shape, workability is extremely good, and by stacking it in a short area and storing a large amount in a small area, storage is also very good.

更に本考案のロープはナイフで切断できるので現物に合
わせて加工する事が出来る。切り口はほどけない様に接
着テープを巻くだけでよい。Furthermore, since the rope of the present invention can be cut with a knife, it can be processed according to the actual product. All you have to do is wrap the adhesive tape so that the cut end does not come loose.

機械で編むため納期が短く、最大利点はゴムに比べて相
当安価なことである。Since it is knitted with a machine, the delivery time is short, and the biggest advantage is that it is considerably cheaper than rubber.

重量製品は貯蔵から運搬車、販売先貯蔵場と度々積み替
えが行われるが、本考案による梱包用緩衝材は、従来の
ゴム帯に比し取替え必要品が少なく、例え切断しても取
替えは極めて簡単である。Although heavy products are often transshipped from storage to trucks and sales stores, the packing cushioning material according to the present invention requires less replacement than conventional rubber bands, and even if cut, replacement is extremely difficult. It's easy.

上記の多数の有利点からその製品の販売促進に寄与する
点が大きい。Many of the above advantages contribute to the promotion of the product.

本考案に係る梱包用緩衝材の用途は必ずしも重量物に限
定されるものではなく、積み上げられたり、表面の傷付
きが問題となる大型物例えば木造建築の飾り性などにも
利用出来る。The use of the cushioning material for packaging according to the present invention is not necessarily limited to heavy objects, but it can also be used for large objects such as piled up and surface scratches, for example, decorative properties of wooden construction.
