FIG. 3 is a perspective view showing the nails of the fish and shellfish collecting tool according to the present embodiment. FIG. 4 is a diagram further showing the nails of the fish and shellfish collecting tool according to the present embodiment. 4(a) is a front view, FIG. 4(b) is a bottom view, and FIG. 4(c) is a cross-sectional view taken along the line AA of the bottom view of FIG. 4(b).

魚介類採取具の爪１０は、第１方向に延び、魚介類採取具に取り付ける基部１２と、基部１２が延びる第１方向から第２方向に方向を転換する屈曲部１５と、屈曲部１５から第２方向に延び、海底の土壌を掘り起こすための爪先を取り付ける先端部１６とを有する弾性金属線材１１を有している。弾性金属線材１１は、所定径を有するばね鋼によって構成されてもよい。 The claw 10 of the seafood collecting tool extends in the first direction and is attached to the seafood collecting tool, the base portion 12, the bent portion 15 that changes the direction from the first direction in which the base portion 12 extends to the second direction, and the bent portion 15. It has an elastic metal wire 11 extending in the second direction and having a tip portion 16 for attaching a toe for excavating soil on the seabed. The elastic metal wire 11 may be made of spring steel having a predetermined diameter.

また、魚介類採取具の爪１０は、弾性金属線材１１の少なくとも屈曲部１５を覆うように、弾性金属線材１１に嵌められた金属管１９を有している。金属管１９は、弾性金属線材１１との間に所定の間隙を有するように所定の内径を有している。金属管１９は、鋼管で構成されてよく、ステンレス鋼管で構成されてもよい。 Further, the claw 10 of the fish collecting tool has a metal tube 19 fitted to the elastic metal wire 11 so as to cover at least the bent portion 15 of the elastic metal wire 11. The metal tube 19 has a predetermined inner diameter so as to have a predetermined gap with the elastic metal wire 11. The metal tube 19 may be a steel tube or a stainless steel tube.

弾性金属線材１１の基部１２は、魚介類採取具に取り付けるために弾性金属線材１１の一端１１ａが所定の形状に曲げられた第１曲げ部１３を有している。第１曲げ部１３は、この魚介類採取具の爪１０を魚介類採取具の桁にボルトとナットとで取り付けるために適した形状であってもよい。 The base portion 12 of the elastic metal wire 11 has a first bent portion 13 in which one end 11a of the elastic metal wire 11 is bent into a predetermined shape in order to be attached to the fish and shellfish collecting tool. The first bent portion 13 may have a shape suitable for attaching the claw 10 of the seafood collecting tool to the girder of the seafood collecting tool with bolts and nuts.

弾性金属線材１１の基部１２は、弾性金属線材１１の一端１１ａに形成された第１曲げ部１３に隣接して緩衝部１４を有している。緩衝部１４は、第１方向及び第２方向を含む面内において、魚介類採取具に取り付けられた第１曲げ部１３に対するこの魚介類採取具の爪１０の角度の変動を緩衝している。緩衝部１４は、第１方向及び第２方向に直交する方向を軸として弾性金属線材１１が巻かれてなるコイルばねによって構成されている。緩衝部１４によって、海底の土壌を掘り起こしてホタテ貝を採取するときにホタテ貝に与える衝撃が和らげられ、ホタテ貝の損傷が低減される。 The base portion 12 of the elastic metal wire rod 11 has a buffer portion 14 adjacent to the first bent portion 13 formed at the one end 11 a of the elastic metal wire rod 11. The cushioning portion 14 cushions the variation in the angle of the claw 10 of the fish collecting tool with respect to the first bending portion 13 attached to the fish collecting tool in the plane including the first direction and the second direction. The cushioning portion 14 is composed of a coil spring formed by winding the elastic metal wire 11 around a direction orthogonal to the first direction and the second direction as an axis. The buffer portion 14 reduces the impact on the scallops when the soil on the seabed is dug up and the scallops are collected, and damage to the scallops is reduced.

弾性金属線材の屈曲部１５は、基部１２が延びる第１方向から先端部１６が延びる第２方向に弾性金属線材１１が延びる方向を転換している。屈曲部１５において、弾性金属線材１１は、第１方向及び第２方向を含む面内において所定径の円周の一部を形成してもよい。ここでは、屈曲部１５は、頂角が略１２０°をなす円弧によって構成されている。 The bent portion 15 of the elastic metal wire changes the direction in which the elastic metal wire 11 extends from the first direction in which the base 12 extends to the second direction in which the tip 16 extends. In the bent portion 15, the elastic metal wire rod 11 may form a part of a circumference having a predetermined diameter in a plane including the first direction and the second direction. Here, the bent portion 15 is formed by an arc having an apex angle of about 120°.

本実施の形態において、弾性金属線材１１の屈曲部１５には、金属管１９が嵌められている。金属管１９は、少なくとも弾性金属線材１１の屈曲部１５を覆うものであればよく、さらに基部１２及び／又は先端部１６の一部を覆うように延長されてもよい。金属管１９は、弾性金属線材１１が屈曲部１５を形成するように曲げ加工される前の段階において、予め弾性金属線材１１の屈曲部１５に相当する部分に嵌められ、弾性金属線材１１が屈曲部１５に曲げ加工されるときに同時に曲げられる。曲げ加工の後で、金属管１９は、屈曲部１５を含む弾性金属線材１１とともに熱処理されてもよい。 In the present embodiment, a metal tube 19 is fitted in the bent portion 15 of the elastic metal wire rod 11. The metal tube 19 may cover at least the bent portion 15 of the elastic metal wire 11, and may be extended so as to cover a part of the base portion 12 and/or the tip portion 16. The metal tube 19 is fitted in a portion corresponding to the bent portion 15 of the elastic metal wire 11 in advance before the elastic metal wire 11 is bent to form the bent portion 15, and the elastic metal wire 11 is bent. When the part 15 is bent, it is bent at the same time. After bending, the metal tube 19 may be heat-treated with the elastic metal wire 11 including the bent portion 15.

弾性金属線材１１の先端部１６は、海底の土壌を掘り起こす爪先を取り付けるために弾性金属線材１１の他端１１ｂが所定の形状の曲げられた第２曲げ部１７を有している。第２曲げ部１７は、この魚介類採取具の爪１０に爪先を取り付けるために適した形状であってもよい。 The tip 16 of the elastic metal wire 11 has a second bent portion 17 in which the other end 11b of the elastic metal wire 11 is bent in a predetermined shape in order to attach a toe for digging soil on the seabed. The second bent portion 17 may have a shape suitable for attaching a toe to the nail 10 of the fish and shellfish collecting tool.

本実施の形態の魚介類採取具の爪１０においては、弾性金属線材１１の屈曲部１５に金属管１９が嵌められ、屈曲部１５を覆って保護している。この魚介類採取具の爪１０を用いてホタテ貝を採取するときに、ホタテ貝は金属管１９によって阻止され、屈曲部１５に衝突することがない。したがって、屈曲部１５にホタテ貝が衝突することによる屈曲部１５の破損を防止することができる。また、従来の魚介類採取具の爪のような挟み板などの部材を必要としない。 In the claw 10 of the fish and shellfish collecting tool according to the present embodiment, the metal tube 19 is fitted into the bent portion 15 of the elastic metal wire 11, and the bent portion 15 is covered and protected. When collecting scallops using the claws 10 of this seafood collecting tool, the scallops are blocked by the metal tube 19 and do not collide with the bent portion 15. Therefore, it is possible to prevent breakage of the bent portion 15 due to the scallop colliding with the bent portion 15. Further, it does not require a member such as a sandwich plate such as a nail of a conventional fish and shellfish collecting tool.

本実施の形態の魚介類採取具の爪１０は、弾性金属線材１１の屈曲部１５に金属管１９が嵌められているため、屈曲部１５における強度が向上する。また、製造工程において、曲げ加工前の段階において予め弾性金属線材１１に金属管１９を嵌めて、弾性金属線材１１と金属管１９とを同時に曲げ加工するため、製造が容易である。曲げ加工時に弾性金属線材１１が金属管１９によって覆われて保護されているため、曲げ加工によって弾性金属線材１１に傷がつくことを防止することができる。さらに、屈曲部１５を金属管１９で覆って保護しているため、樹脂で覆った場合に起こり得るような海洋をプラスチックにより汚染する心配がない。 In the nail 10 of the fish and shellfish collecting tool according to the present embodiment, the metal tube 19 is fitted into the bent portion 15 of the elastic metal wire 11, so that the strength of the bent portion 15 is improved. Further, in the manufacturing process, the metal pipe 19 is fitted in advance to the elastic metal wire rod 11 before the bending work, and the elastic metal wire rod 11 and the metal pipe 19 are bent at the same time, so that the manufacturing is easy. Since the elastic metal wire 11 is covered and protected by the metal tube 19 during bending, it is possible to prevent the elastic metal wire 11 from being damaged by bending. Further, since the bent portion 15 is covered with the metal tube 19 for protection, there is no fear of contaminating the ocean with plastic, which may occur when covered with resin.

図５は、魚介類採取具の爪の第１変形例を示す斜視図である。第１変形例においては、図３及び図４に示した本実施の形態の魚介類採取具の爪１０と対応する構成要素について同様の参照符号を付して対応関係を示すものとする。他の変形例においても同様である。 FIG. 5: is a perspective view which shows the 1st modification of the nail|claw of a seafood sampling tool. In the first modification, the same reference numerals are given to the components corresponding to the claws 10 of the fish and shellfish collecting tool according to the present embodiment shown in FIGS. 3 and 4, and the corresponding relationships are shown. The same applies to other modified examples.

第１変形例の魚介類採取具の爪１０は、第１方向に延びる基部１２と、基部１２が延びる第１方向から第２方向に方向を転換する屈曲部１５と、屈曲部１５から第２方向に延びる先端部１６とを有する弾性金属線材１１を有している。基部１２には、弾性金属線材１１の一端１１ａに魚介類採取具に取り付けるための第１曲げ部１３が形成され、第１曲げ部に隣接して弾性金属線材１１がコイル状に巻かれた緩衝部１４が形成されている。先端部１６には、弾性金属線材１１の他端１１ｂに海底の土壌を掘り起こすための爪先２０を取り付けるための第２曲げ部１７が形成されている。また、第１変形例の魚介類採取具の爪１０は、弾性金属線材１１の少なくとも屈曲部１５を覆うように、弾性金属線材１１に嵌められた金属管１９を有している。 The claw 10 of the fish collecting tool according to the first modified example includes a base portion 12 extending in the first direction, a bent portion 15 that changes the direction from the first direction in which the base portion 12 extends to the second direction, and the bent portion 15 to the second portion. The elastic metal wire rod 11 has a tip portion 16 extending in the direction. The base portion 12 has a first bent portion 13 formed at one end 11a of the elastic metal wire rod 11 for attaching to a fish and shellfish collecting tool, and a buffer in which the elastic metal wire rod 11 is wound in a coil shape adjacent to the first bent portion. The part 14 is formed. A second bent portion 17 for attaching a toe 20 for digging up soil on the seabed is formed on the other end 11b of the elastic metal wire 11 at the tip portion 16. The claw 10 of the fish and shellfish collecting tool of the first modified example has a metal tube 19 fitted to the elastic metal wire 11 so as to cover at least the bent portion 15 of the elastic metal wire 11.

第１変形例の魚介類採取具の爪１０は、屈曲部１５が略９０°の頂角を有する円弧によって構成されている点で、屈曲部１５が略１２０°の頂角を有する円弧によって構成された図３及び図４に示した本実施の形態の魚介類採取具の爪１０と相違している。他の構成については、前記本実施の形態の魚介類採取具の爪１０と同様である。 The claw 10 of the fish collecting tool of the first modified example is configured such that the bent portion 15 is formed of an arc having an apex angle of approximately 90°, and the bent portion 15 is formed of an arc having an apex angle of approximately 120°. This is different from the claw 10 of the fish and shells collecting tool of the present embodiment shown in FIGS. 3 and 4. Other configurations are the same as those of the claw 10 of the fish and shellfish collecting tool of the present embodiment.

図５においては、弾性金属線材１１の先端部１６の第２曲げ部１７に取り付けられた爪先２０も併せて示されている。爪先２０は、海底の土壌を掘り起こすために延びたエッジ２１と、この爪先２０を第２曲げ部１７に取り付けるための結合部２２とを有している。 In FIG. 5, the toe 20 attached to the second bent portion 17 of the tip portion 16 of the elastic metal wire 11 is also shown. The toe 20 has an edge 21 extending to dig up the soil on the sea floor, and a joint portion 22 for attaching the toe 20 to the second bent portion 17.

第１変形例の魚介類採取具の爪１０においても、弾性金属線材１１の屈曲部１５に金属管１９が嵌められ、屈曲部１５は金属管１９によって覆われて保護されている。したがって、爪先２０のエッジ２１で海底の土壌を掘り起こしてホタテ貝を採取するときに、ホタテ貝が屈曲部１５に衝突して屈曲部１５を破損することが防止されている。他にも、前記本実施の形態の魚介類採取具の爪１０と同様の効果を有する。 Also in the claw 10 of the fish and shellfish collecting tool of the first modified example, the metal tube 19 is fitted into the bent portion 15 of the elastic metal wire 11, and the bent portion 15 is covered and protected by the metal tube 19. Therefore, when the soil on the seabed is dug up at the edge 21 of the toe 20 to collect the scallop, the scallop is prevented from colliding with the bent portion 15 and damaging the bent portion 15. Besides, it has the same effect as the claw 10 of the seafood collecting tool of the present embodiment.

図６は、魚介類採取具の爪の第２変形例を示す斜視図である。第２変形例の魚介類採取具の爪１０は、第１方向に延びる基部１２と、基部１２が延びる第１方向から第２方向に方向を転換する屈曲部１５と、屈曲部１５から第２方向に延びる先端部１６とを有する弾性金属線材１１を有している。基部１２には、弾性金属線材１１の一端１１ａに魚介類採取具に取り付けるための第１曲げ部１３が形成されている。 FIG. 6 is a perspective view showing a second modified example of the nail of the fish and shellfish collecting tool. The claw 10 of the fish and shellfish collecting tool of the second modified example has a base portion 12 extending in the first direction, a bent portion 15 that changes the direction from the first direction in which the base portion 12 extends to the second direction, and the bent portion 15 to the second portion. The elastic metal wire rod 11 has a tip portion 16 extending in the direction. The base portion 12 has a first bent portion 13 formed at one end 11a of the elastic metal wire 11 for attaching to a fish and shellfish collecting tool.

第２変形例の屈曲部１５は、第１方向から第２方向に向かう第３方向に方向を転換した後で第３方向から第２方向に方向を転換するように２箇所の曲げで形成されている。先端部１６には、弾性金属線材１１の他端１１ｂに海底の土壌を掘り起こすための爪先２０を取り付けるための第２曲げ部１７が形成されている。また、第２変形例の魚介類採取具の爪１０は、弾性金属線材１１の基部１２の一部及び屈曲部１５を覆うように、弾性金属線材１１に嵌められた金属管１９を有している。図６においては、弾性金属線材１１の先端部１６の第２曲げ部１７に取り付けられた爪先２０も併せて示されている。 The bent portion 15 of the second modification is formed by bending at two places so as to change the direction from the first direction to the second direction and then to change the direction from the third direction to the second direction. ing.
