Description

本考案は、海苔養殖時に海苔網と海苔網を固定するためのロープ間に使用される連結用フックに関する。  The present invention relates to a connecting hook used between a nori net and a rope for fixing the nori net during nori cultivation.

海苔養殖時に海苔網を漁場へ固定する為に、周囲にブイまたは棒木設置する。それらから直接的または間接的に引き出したロープに耳網との脱着が容易なフックをつけて海苔網が四方向へ広がるように使用されてきた。
このようなフックに関する従来技術として特許文献1〜4が提案されている。特許文献1は、耳網の太さのばらつきがあっても外れにくいフックが記載されている。特許文献2及び3は、海苔網を固定する際の作業効率を上げるための技術が記載されている。特許文献4は、弾性材料を用いており、耳網を係止するために切り込みを指で押し開いて装着するため、外れにくく海苔網の網紐に引っ掛かりにくい技術が記載されている。
In order to fix the seaweed net to the fishing ground during seaweed cultivation, buoys or sticks are installed around it. It has been used so that nori nets spread in four directions by attaching hooks that can be easily detached from ear nets to ropes drawn directly or indirectly from them.
Patent documents 1 to 4 have been proposed as conventional techniques related to such a hook. Patent Document 1 describes a hook that does not easily come off even if the thickness of the ear net varies. Patent Documents 2 and 3 describe techniques for increasing work efficiency when fixing a laver net. Patent Document 4 describes a technology that uses an elastic material and pushes the notch with a finger in order to lock the ear net, so that it does not easily come off and is not easily caught by the net string of the laver net.

特開昭61−74933JP-A 61-74933 特開平7−327533JP-A-7-327533 特開2001−148952JP2001-148952A 実登3028289Actual climb 3028289

特許文献1〜3に記載の従来技術のフックは、耳穴を通す入り口形状が開いた状態である。また、特許文献4に記載の従来技術のフックは、耳穴を通す入り口形状はしまった状態であるが、弾性材料を用いているため耳網が引っ張られると切り込み部が開いてしまうことは容易に考えることができる。
このような従来技術のフックでは、海苔網の設置後に海が荒れた場合等に、当該海苔網の網紐が引っ掛かる事態や、別の海苔網の耳網や網紐が引っ掛かる事態が発生してしまう。海苔網を構成する網紐は耳網に比べて細い構造であるため、フックに引っ掛かった状態では時間とともに負荷が高くなり切れる事が多い。またそれが一度ではなく繰り返し発生する事となると、網全体が大きく損なわれてしまう事になる。
The prior art hooks described in Patent Documents 1 to 3 are in a state where the shape of the entrance through which the ear hole is passed is opened. In addition, the hook of the prior art described in Patent Document 4 is in a state where the shape of the entrance through which the ear hole is passed, but since the elastic material is used, it is easy for the notch to open when the ear net is pulled. Can think.
In such a prior art hook, when the sea is rough after the laver net is installed, a situation where the net string of the seaweed net is caught or a case where another ear net or net string is caught occurs. End up. Since the net string constituting the laver net is a thin structure compared to the ear net, the load increases with time and often breaks when hooked on the hook. If this happens repeatedly instead of once, the entire network will be greatly damaged.

本考案の請求項1に記載の養殖海苔網用フックは、養殖海苔網の耳網と固定用ロープを連結するためのフックであって、ロープを連結するための貫通した穴を有する連結部と、同連結部から長手方向に伸びたフック本体部と、同フック本体の伸びた先から連結部方向へU字に湾曲することで耳網を係止するための係止部と同係止部への耳網を挿入する挿入口を形成するフック先端部を有し、同係止部に耳網を挿入した後に、同フック先端部とフック本体部を表裏から挟み込むように取り付けることで、同挿入口を塞ぐための蓋部を有することにより、耳網の挿入口から海苔網の網紐が係止部へ挿入し引っ掛かることを防止することができる。
本考案の請求項2に記載の養殖海苔網用フックは、前記フック本体部及び前記フック先端部は、その表裏面に前記蓋部が挟み込む際の長さと幅及び厚さに相当する分を削ることで同蓋部の取り付けを容易に行うためのガイド部を有している。
