The base frame is stretched to form a framework, and the bottom mesh body is stretched on the base frame, and the mesh body is arranged between the base frame and the skeleton located on one end side and around each skeleton. It is stretched so that the upper part of the base frame can be covered in a state of being arranged at a predetermined angle, and a cylindrical fish entry path is provided at an appropriate position of the net body, and the skeleton located on the other end side with the base frame On the other hand, in a foldable fish trap attached with a locking hook for stopping the collapsed skeleton on the base frame, both sides of the base frame where the skeletons are pivotally attached, and the engagement between the base frame and the skeleton At the part where the hook is attached and the part where the hook is locked Is obtained by employing the structure in which a protective member for preventing the wear of the site al.

上記保護部材が、金属もしくは合成樹脂を用いたＣリング又はパイプで形成され、ベース枠又は骨子を形成する金属線材に対して外嵌状に取付けられている構造とすることができる。   The protective member may be formed of a C ring or a pipe using a metal or a synthetic resin, and may be attached to a metal wire that forms a base frame or a frame.

ここで、ベース枠は長円形に形成され、骨子は第１乃至第３の骨子からなり、各骨子のベース枠に対する枢着は、各骨子の両端に屈曲形成した円弧状部を中棧に外嵌して取付けることによって行われ、また、係止フックは、金属線材を用い、一端側に屈曲形成した円弧状部をベース枠に回転可能に取付け、他端側に設けた屈曲部を第３の骨子に対して係脱させることができる構造になっている。   Here, the base frame is formed in an oval shape, and the skeleton is composed of first to third skeletons, and each skeleton is pivotally attached to the base frame with an arcuate portion bent at both ends of each skeleton. The locking hook is made of a metal wire, and an arcuate portion bent at one end is rotatably attached to the base frame, and a bent portion provided at the other end is third. It is structured to be able to be engaged and disengaged with respect to the outline of

また、上記した魚進入路は、網体の部分で開口し、網体から内側へ先端が小径となる筒状の網で形成され、この魚進入路の先端側がベース枠の両側に固定した紐で引っ張り状態に保持され、外部からの魚の侵入を許容し、内側からの魚の脱出を阻止する所謂戻りや返しの機能を有している。   Further, the fish approach path described above is formed of a cylindrical net having an opening at the net portion and having a small diameter inward from the net body, and the fish entrance path is fixed to both sides of the base frame. And has a so-called return and return function that allows fish from the outside to enter and prevents escape of the fish from the inside.

On the upper surface side of the frame 22, first to third skeletons 23 to 25 formed in a U-shape that is substantially half of the base frame 22, using a metal wire that has also been subjected to rust prevention treatment, are attached to the base frame 22. A frame is assembled by pivotally attaching to the intermediate collar 26 so as to be able to turn up and down, and a base net 27 is stretched on the base frame 22, and between the base frame 22 and the first skeleton 23 located on one end side, and The mesh body 28 is stretched along the periphery between the first to third skeletons 23 to 25 so as to cover the upper portion of the base frame 22 in a state where the skeletons 23 to 25 are arranged at a predetermined angle. And between the base frame 22 of the mesh body 28 and the first outline 23, The cylindrical fish entry paths 29 and 29 are provided so as to protrude inwardly between the three main bodies 24 and 25, and the third main body 25 that is tilted on the base frame 22 is provided at the tip of the base frame 22 at the other end side. A locking hook 30 for stopping the frame 22 is attached.

上記の魚進入路２９、２９は、網体２８の部分で開口し、網体２８から内側へ先端が小径となる筒状の網で形成され、この魚進入路２９、２９の先端側がベース枠２２の両側に固定した紐３１で引っ張り状態に保持され、網体２８の内部に対して外部からの魚の侵入を許容し、内側からの魚の脱出を阻止する所謂戻りや返しの機能を有している。   The fish entry paths 29 and 29 are formed by a cylindrical net having an opening at a portion of the net body 28 and having a small diameter at the tip inward from the net body 28, and the tip side of the fish entry paths 29 and 29 is a base frame. 22 has a so-called return and return function that is held in tension by the strings 31 fixed on both sides of the 22 and allows the fish from the outside to enter the inside of the net body 28 and prevents the fish from escaping from the inside. Yes.

上記第１乃至第３の骨子２３乃至２５のベース枠２２に対する枢着は、各骨子２３乃至２５の両端に屈曲形成した円弧状部３２を中棧２６に外嵌して取付けることによって行われ、また、係止フック３０は、ステンレスのような金属線材を用い、一端側に屈曲形成した円弧状部３３をベース枠２２に回転可能に取付け、他端側に設けた屈曲部３４を第３の骨子２５に対して係脱させることができる構造になっている。   The first to third skeletons 23 to 25 are pivotally attached to the base frame 22 by attaching the arcuate portions 32 bent at both ends of the respective skeletons 23 to 25 to the inner collar 26 and attaching them. The locking hook 30 is made of a metal wire such as stainless steel, and an arcuate portion 33 bent at one end side is rotatably attached to the base frame 22 and a bent portion 34 provided at the other end side is attached to a third portion. The structure can be engaged with and disengaged from the main body 25.

上記のような折り畳み式の魚捕獲器２１において、ベース枠２２の各骨子２３乃至２５を枢着した中棧２６の両側の部位と、前記ベース枠２２の係止フック３０を取付けた部分及び第３の骨子２５の係止フック３０を係止する部位の合計四箇所の位置に、これらの部位の摩耗を防ぐと共に、耐食性を維持するための保護部材３５が取付けられている。   In the foldable fish catcher 21 as described above, the parts on both sides of the center rod 26 to which the skeletons 23 to 25 of the base frame 22 are pivotally attached, the portions where the locking hooks 30 of the base frame 22 are attached, and the first Protective members 35 for preventing wear of these portions and maintaining corrosion resistance are attached to a total of four positions where the locking hooks 30 of the third skeleton 25 are locked.

この保護部材３５は、図４の（ｂ）と(ｃ)に示すように、ステンレス、真鍮等の金属もしくはビニール等の合成樹脂を用いたＣリング又はパイプで形成され、Ｃリングの場合は骨組みの組み立て後に後付けで、また、パイプの場合は骨組みの組み立て前に先付けによって取付け、ベース枠２２又は骨子２５を形成する金属線材に対して外嵌状となるようカシメ等によって固定されている。   As shown in FIGS. 4B and 4C, the protective member 35 is formed of a C ring or a pipe using a metal such as stainless steel or brass, or a synthetic resin such as vinyl. In the case of a pipe, the pipe is attached by prior attachment before assembling the frame, and is fixed by caulking or the like so as to be externally fitted to the metal wire forming the base frame 22 or the skeleton 25.

上記のような保護部材３５の取付けによって、ベース枠２２に対する第１乃至第３の骨子２３乃至２５の両端に屈曲形成した円弧状部３２と係止フック３０の円弧状部３３は保護部材３５に外嵌し、かつ、係止フック３０の第３の骨子２５に対する係脱は保護部材３５を介して行われるので、ベース枠２２及び第３の骨子２５に対して、第１乃至第３の骨子２３乃至２５と係止フック３０は直接的な接触部分が生じないことになり、これにより、ベース枠２２及び第３の骨子２５の摩耗発生と防錆処理の損傷発生を防ぐことになる。   By attaching the protective member 35 as described above, the arc-shaped portion 32 bent at both ends of the first to third skeletons 23 to 25 with respect to the base frame 22 and the arc-shaped portion 33 of the locking hook 30 become the protective member 35. Since the outer fitting and the engagement / disengagement of the locking hook 30 with respect to the third skeleton 25 are performed via the protective member 35, the first to third skeletons with respect to the base frame 22 and the third skeleton 25 are provided. 23 to 25 and the locking hook 30 do not cause a direct contact portion, thereby preventing the base frame 22 and the third skeleton 25 from being worn and rust-proofing from being damaged.

なお、折り畳み式の魚捕獲器が大型の場合、係止フック３０はベース枠２２の幅方向の両側に二個が取り付けられた構造となり、従って、保護部材３５は、ベース枠２２において、両係止フック３０の取付け部分と、第３の骨子２５の両係止フック３０が係脱する二箇所の位置に取付けることになり、保護部材３５は合計六箇所に取付けられることになる。   When the foldable fish catcher is large, two locking hooks 30 are attached to both sides of the base frame 22 in the width direction. Therefore, the protective member 35 is coupled to the base frame 22 in both directions. It will be attached at two positions where the attachment portion of the stop hook 30 and both locking hooks 30 of the third skeleton 25 are engaged and disengaged, and the protection member 35 will be attached at a total of six locations.

The same parts as those in the first embodiment described above are denoted by the same reference numerals and are not described here.

この第２の実施の形態の魚捕獲器２１は、ベース枠２２の上面で両側位置に略半円形の取付け軸３６を立設し、第１乃至第４の骨子３７乃至４０の両端に屈曲形成した円弧状部３２を取付け軸３６に外嵌して取付け、ベース枠２２と一端側に位置する第１骨子３７の間及び各第１乃至第４の骨子３７乃至４０間の周囲に沿って網体２８を、各骨子３７乃至４０を所定角度の配置にした状態でベース枠２２の上部を覆うことができるように張設し、この網体２８のベース枠２２と第１骨子３７の間と、第３と第４の骨子３９、４０間に筒状の魚進入路２９を内側に突出するよう設け、ベース枠２２の他端側に、ベース枠２２上に倒した第４の骨子４０をベース枠２２に対して止めるための係止フック３０を取付けた構造になっている。   In the fish catcher 21 of the second embodiment, a substantially semicircular mounting shaft 36 is erected on both sides of the upper surface of the base frame 22 and bent at both ends of the first to fourth skeletons 37 to 40. The arcuate portion 32 is fitted onto the attachment shaft 36, and the mesh is formed between the base frame 22 and the first skeleton 37 located on one end side and between the first to fourth skeletons 37 to 40. The body 28 is stretched so as to be able to cover the upper part of the base frame 22 in a state where the respective frames 37 to 40 are arranged at a predetermined angle, and between the base frame 22 of the net body 28 and the first frame 37. A cylindrical fish entry path 29 is provided between the third and fourth skeletons 39 and 40 so as to protrude inward, and a fourth skeleton 40 that is tilted onto the base frame 22 is provided on the other end side of the base frame 22. A locking hook 30 for stopping the base frame 22 is attached.

この折り畳み式の魚捕獲器２１において、上記両側位置の取付け軸３６とベース枠２２の係止フック３０を取付けた部分及び第４の骨子４０の係止フック３０を係止する部位の合計四箇所の位置に、これらの部位の摩耗を防ぐと共に、耐食性を維持する保護部材３５が施されている。   In this foldable fish catcher 21, there are a total of four portions, that is, the portion where the mounting shaft 36 on both sides and the locking hook 30 of the base frame 22 are mounted and the portion where the locking hook 30 of the fourth skeleton 40 is locked. In this position, a protective member 35 for preventing the wear of these parts and maintaining the corrosion resistance is provided.

図８（ｃ）は、取付け軸３６に対する保護部材３５の取付け構造を示し、保護部材３５は、略半円形となる取付け軸３６の形状に合わせて弧状に成形したＣリングを、取付け軸３６に外嵌してカシメ等の手段で固定するものである。   FIG. 8C shows an attachment structure of the protection member 35 to the attachment shaft 36, and the protection member 35 has a C ring formed in an arc shape in accordance with the shape of the attachment shaft 36 that is substantially semicircular. It is externally fitted and fixed by means such as caulking.

この発明の魚捕獲器は、上記のような構成であり、第１の実施の形態の魚捕獲器２１の場合、使用しないとき、第１乃至第３の骨子２３乃至２５をその間に網体２８が収まるようにベース枠２２上の片側に折り畳み、全体を薄い扁平状とすることにより、嵩張らないようになっている。   The fish trap of the present invention is configured as described above.
