Description
【考案の詳細な説明】 (a)産業上の利用分野 本考案は、旋網漁の魚網に付属した親子環に関するもの
である。[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a parent-child ring attached to a fishnet for purse seine fishing.
(b)従来の技術 従来、旋網漁の魚網に付属した親子環（Ｂ）は、丸棒を
環状に加工した親環に子環を入れた物であった。(b) Conventional Technology Conventionally, the parent and child ring (B) attached to a fishnet for purse seine fishing was a parent ring formed by processing a round bar into a ring and inserting the child ring.
(c)考案が解決しようとする問題点 しかし、この親環は内側を通るワイヤーロープによる
摩耗が激しく短期間の使用で摩滅し新品と交換している
のが現状であった。本考案は上記の欠点を除いて親子環
の耐用時間を伸ばし親子環取替に伴う手間と旋網漁の経
費削減に貢献できるものである。(c) Problems to be solved by the invention However, this parent ring was worn out by a wire rope passing through the inside and was worn out after a short period of use and had to be replaced with a new one. The present invention eliminates the above-mentioned drawbacks and extends the useful life of the parent-child ring, and can contribute to the labor required for replacing the parent-child ring and the reduction of the cost of purse seine fishing.
(d)問題点を解決する手段 既存の親子環（Ｂ）の親環は、断面形状が円形であ
り内側を通るワイヤーロープとの接触面積が小さく短期
間で摩滅していたが本考案の親子環（Ａ）の親環にお
いては、断面形状を特殊形状にし内側を通るワイヤーロ
ープとの接触面積を増大させた事を特徴としまた揚網時
の親子環の取り扱いは人力にたよっている為親子環の重
量は従来のものと同程度に保っている。(d) Means for solving the problem The parent ring of the existing parent-child ring (B) had a circular cross-sectional shape and a small contact area with the wire rope passing through the inside, and was worn out in a short period of time. The parent ring of the ring (A) is characterized by having a special cross-sectional shape to increase the contact area with the wire rope that passes through the inside, and because the parent-child ring is handled manually when the net is netted, the parent and child The weight of the ring is kept similar to the conventional one.
(e)作用 上記の様に親環とワイヤーロープとの接触面積を増大
させる事により親環の耐摩耗性が増大し、著しく親子
環（Ａ）の耐用時間が増大される。(e) Action By increasing the contact area between the parent ring and the wire rope as described above, the wear resistance of the parent ring is increased and the service life of the parent ring (A) is significantly increased.
(f)考案の効果 実地例について述べると既存の親子環（Ｂ）と同様の取
り扱いを行いその結果を調査してみたが既存の親子環
（Ｂ）に比べ耐摩耗性は増大し、耐用時間にして５〜６
倍もの伸びを見せた。また親子環（Ａ）の耐用時間増大
に呼応して使用しているワイヤーロープの寿命も増大
し、更に環巻き行程時には円滑な環の滑りが得られた。
種々の点より長期間のスムーズな環巻き作業が可能とな
ると同時に海中に張られた網の形状にも良い結果が得ら
れるのである。(f) Effect of the invention To describe a practical example, the same treatment as the existing parent-child ring (B) was conducted and the results were investigated, but the wear resistance was increased compared to the existing parent-child ring (B), and the service life was increased. 5-6
It showed double the growth. In addition, the life of the wire rope used was extended in response to the increase in the service life of the parent-child ring (A), and smooth ring slip was obtained during the ring winding process.
From various points, it is possible to perform a smooth winding work for a long period of time, and at the same time, good results can be obtained for the shape of the net stretched in the sea.
