第2の構成の釣り針においては、製造時の歩留まり及び作業効率を向上させ、製造コストの低減を図ることができる。つまり、これを製造するに当たり、第1針部と第2針部とを有する第1針体と、第3針部と第4針部とを有する第2針体とを重ね合わせ、第1軸部と、第2軸部と、第3軸部と、第4軸部とをチューブ体に挿入するだけで、複数の針部が略錨形状に組まれた製造中間品(加熱前ユニット)を簡単かつ速やかに組み上げることができ、この加熱前ユニットを加熱処理することにより、チューブ体によって、上記各軸部を簡単かつ確実に結束でき、さらに、チューブ体の内側に設けられた接着剤によって、チューブ体と、上記各軸部と、接着剤とが一体化していることにより、上記結束状態がより確実なものとなる。よって、略錨形状を呈する釣り針において、製造作業者の習熟度を問わず、一定の品質で、品質の安定した釣り針を、歩留まり良く、かつ、効率良く得ることができる。   In the fishing hook of the second configuration, the yield and work efficiency at the time of manufacturing can be improved, and the manufacturing cost can be reduced. That is, in manufacturing this, the first needle body having the first needle portion and the second needle portion and the second needle body having the third needle portion and the fourth needle portion are overlapped to form the first shaft. An intermediate product (unit before heating) in which a plurality of needle parts are assembled in a substantially bowl shape simply by inserting the part, the second shaft part, the third shaft part, and the fourth shaft part into the tube body By simply heat-treating this pre-heating unit, the above-mentioned shaft portions can be easily and reliably bound by the tube body, and further, by an adhesive provided inside the tube body, Since the tube body, each of the shaft portions, and the adhesive are integrated, the above-described binding state is more reliable. Therefore, in the fishing hook having a substantially rod shape, a fishing hook having a constant quality and a stable quality can be obtained with high yield and efficiency regardless of the level of proficiency of the manufacturer.

また、第3には、上記第1又は第2の構成において、接着剤は、熱収縮前のチューブ体(32’、62’)の内周面に設けられたホットメルト接着剤層(34’、64’)が、チューブ体を収縮させるための加熱処理の際に、融解し、放熱により再固化したものであることを特徴とする。   Thirdly, in the first or second configuration, the adhesive is a hot melt adhesive layer (34 ′) provided on the inner peripheral surface of the tube body (32 ′, 62 ′) before heat shrinkage. 64 ′) is characterized in that it is melted and re-solidified by heat radiation during the heat treatment for shrinking the tube body.

第3の構成の釣り針においては、製造時の歩留まり及び作業効率をさらに向上させ、製造コストのさらなる低減を図ることができる。つまり、例えば、チューブ体の加熱処理後に、熱収縮したチューブ体の内側に接着剤を注入する場合、狭い隙間に接着剤を注入する必要があるため、十分な量の接着剤を充填できないこともあり得るが、本構成のものにおいては、チューブ体と各軸部との間にホットメルト接着剤層を確実に設けることができ、また加熱処理の際、各軸部どうしの隙間に接着剤の融液が浸透するので、チューブ体の内側を接着剤で埋め尽くし、接着をより確実なものとすることができる。   In the fishing hook of the third configuration, it is possible to further improve the production yield and work efficiency, and further reduce the production cost. In other words, for example, when the adhesive is injected into the heat-shrinkable tube body after the heat treatment of the tube body, it is necessary to inject the adhesive into a narrow gap, so that a sufficient amount of adhesive may not be filled. However, in this configuration, a hot melt adhesive layer can be reliably provided between the tube body and each shaft portion, and the adhesive can be placed in the gap between the shaft portions during the heat treatment. Since the melt permeates, the inside of the tube body can be filled with an adhesive, and adhesion can be made more reliable.

第4の構成の釣り針の製造方法においては、製造時の歩留まり及び作業効率を向上させ、製造コストの低減を図ることができる。つまり、第1針部と第2針部とを有する第1針体の第1折り返し部に、第3針部と第4針部とを有する第2針体の第2折り返し部を差し込むだけで、複数の針部が略錨形状に組まれた製造中間品(針体ユニット)を簡単かつ速やかに組み上げることができ、この針体ユニットの第1軸部と、第2軸部と、第3軸部と、第4軸部とをチューブ体に挿入し、チューブ体を加熱処理することにより、収縮したチューブ体によって、上記各軸部を簡単かつ確実に結束でき、さらに、チューブ体の内側に設けられた接着剤によって、チューブ体と、上記各軸部と、接着剤とが一体化していることにより、上記結束状態がより確実なものとなる。よって、略錨形状を呈する釣り針において、製造作業者の習熟度を問わず、一定の品質で、品質の安定した釣り針を、歩留まり良く、かつ、効率良く得ることができる。   In the manufacturing method of the fishing hook of the 4th structure, the yield and work efficiency at the time of manufacture can be improved, and reduction of manufacturing cost can be aimed at.

第6の構成の釣り針の製造方法においては、製造時の歩留まり及び作業効率を向上させ、製造コストの低減を図ることができる。つまり、第1針部と第2針部とを有する第1針体と、第3針部と第4針部とを有する第2針体とを重ね合わせ、第1軸部と、第2軸部と、第3軸部と、第4軸部とをチューブ体に挿入するだけで、複数の針部が略錨形状に組まれた製造中間品(加熱前ユニット)を簡単かつ速やかに組み上げることができ、この加熱前ユニットを加熱処理することにより、チューブ体によって、上記各軸部を簡単かつ確実に結束でき、さらに、チューブ体の内側に設けられた接着剤によって、チューブ体と、上記各軸部と、接着剤とが一体化していることにより、上記結束状態がより確実なものとなる。よって、略錨形状を呈する釣り針において、製造作業者の習熟度を問わず、一定の品質で、品質の安定した釣り針を、歩留まり良く、かつ、効率良く得ることができる。   In the method for manufacturing a fishing hook of the sixth configuration, the yield and work efficiency at the time of manufacturing can be improved, and the manufacturing cost can be reduced. In other words, the first needle body having the first needle portion and the second needle portion and the second needle body having the third needle portion and the fourth needle portion are overlapped, and the first shaft portion and the second shaft By simply inserting the head portion, the third shaft portion, and the fourth shaft portion into the tube body, a production intermediate product (unit before heating) in which a plurality of needle portions are assembled in a substantially bowl shape can be easily and quickly assembled. By heating the unit before heating, the shaft portions can be easily and surely bound by the tube body, and further, the tube body and each of the above-described parts can be bonded by an adhesive provided inside the tube body. Since the shaft portion and the adhesive are integrated, the above-described bundling state is more reliable. Therefore, in the fishing hook having a substantially rod shape, a fishing hook having a constant quality and a stable quality can be obtained with high yield and efficiency regardless of the level of proficiency of the manufacturer.

また、第7には、上記第6の構成において、加熱前ユニット形成工程において、略直角に交差する第1溝部と第2溝部が設けられた板状の保持部における第1溝部に第1本体部と第3本体部を配置するとともに、第2溝部に第2本体部と第4本体部を配置した状態で、固定具を取り付けることを特徴とする。   Seventhly, in the sixth configuration, in the pre-heating unit formation step, the first main body is formed in the first groove portion in the plate-like holding portion provided with the first groove portion and the second groove portion intersecting at substantially right angles.

第7の構成の釣り針の製造方法においては、製造時の歩留まり及び作業効率をさらに向上させ、製造コストのさらなる低減を図ることができる。つまり、各針部における各本体部の側部が各溝部の側面によって支持されるので、加熱前ユニットの据わりが安定し、また加熱前ユニットにおける各軸部が保持部に対して略垂直に保持され、各軸部に取り付けられている固定具が傾かないので、チューブ体の内側において、ホットメルト接着剤層の融液が均等に拡散、浸透することから、再固化した接着剤が偏在せず、品質がより安定した釣り針を、さらに歩留まり良く、かつ、さらに効率良く得ることができる。   In the method for manufacturing a fishing hook of the seventh configuration, the yield and work efficiency at the time of manufacturing can be further improved, and the manufacturing cost can be further reduced. In other words, the side part of each main body part in each needle part is supported by the side surface of each groove part, so that the unit before heating is stable and each shaft part in the unit before heating is held substantially perpendicular to the holding part. Since the fixture attached to each shaft part does not tilt, the melt of the hot melt adhesive layer diffuses and penetrates evenly inside the tube body, so that the re-solidified adhesive is not unevenly distributed. Further, a fishing hook with more stable quality can be obtained with higher yield and further efficiency.

なお、上記第7の構成において、第1溝部と第2溝部の深さが、第1針体における第1本体部の下端から第1軸部の下端までの長さ及び第2本体部の下端から第2軸部の下端までの長さよりも短く形成されるとともに、第2針体における第3本体部の下端から第3軸部の下端までの長さ及び第4本体部の下端から第4軸部の下端までの長さよりも短く形成されているものとしてもよい。   In the seventh configuration, the depth of the first groove portion and the second groove portion is the length from the lower end of the first main body portion to the lower end of the first shaft portion in the first needle body and the lower end of the second main body portion. To the lower end of the second shaft portion, the length from the lower end of the third main body portion to the lower end of the third shaft portion in the second needle body, and the lower end of the fourth main body portion to the fourth. It is good also as what is formed shorter than the length to the lower end of an axial part.

本発明に基づく釣り針及びその製造方法によれば、複数の針部を有する第1針体と、第1針体と同一の構成を有する第2針体とを、加熱により収縮するチューブ体により、結束することによって、誰にでも簡単、迅速、かつ、確実に錨形状を呈する釣り針を形成することができ、チューブ体の内側に接着剤を設けることにより、確実に結束することができる。よって、製造時の歩留まり及び作業効率を向上させ、製造コストの低減を図ることができる。   According to the fishing hook and the manufacturing method thereof according to the present invention, the first needle body having a plurality of needle portions and the second needle body having the same configuration as the first needle body are heated by a tube body that contracts by heating, By binding, anyone can easily, quickly and surely form a fishing hook having a rod shape, and by providing an adhesive on the inside of the tube body, binding can be ensured. Therefore, the yield and work efficiency at the time of manufacture can be improved and the manufacturing cost can be reduced.

また、チューブ体を、熱収縮前のチューブ体の内周面上にホットメルト接着剤層が設けられたものとすることにより、熱収縮後のチューブ体の内側を隙間なく接着剤で埋め尽くして、接着をより確実なものとすることができる。よって、製造時の歩留まり及び作業効率をさらに向上させ、製造コストのさらなる低減を図ることができる。   In addition, the tube body is provided with a hot-melt adhesive layer on the inner peripheral surface of the tube body before heat shrinkage, so that the inside of the tube body after heat shrinkage is filled with an adhesive without any gaps. Adhesion can be made more reliable. Therefore, the yield and work efficiency at the time of manufacture can be further improved, and the manufacturing cost can be further reduced.

次に、針体10と針体20を組み合わせることにより、針体ユニット7A(図3、図5を参照)を形成する(針体ユニット形成工程)。つまり 針体20の折り返し部22の上端部を、針体10の折り返し部12における軸部14a側と、折り返し部12における軸部16a側との間に差し込み、針体10の中心軸C1で軸部14aと軸部16aとの間を通り、軸部14a及び軸部16aに沿った中心軸C1と、針体20の中心軸C2で軸部24aと軸部26aとの間を通り、軸部24a及び軸部26aに沿った中心軸C2とが略一致し、かつ、針体20の平面方向が針体10の平面方向に対して略直角に交差する(「針体10の平面方向に対して直角に交差する」としてもよい)ように、針体10と針体20との相対位置を調整する。また、針体10と針体20との相対位置を上下方向にずらして、折り返し部12の上端部と折り返し部22の上端部の間に隙間を形成する。   Next, the needle body unit 7A (see FIGS. 3 and 5) is formed by combining the needle body 10 and the needle body 20 (needle body unit forming step). That is, the upper end portion of the folded portion 22 of the needle body 20 is inserted between the shaft portion 14a side of the folded portion 12 of the needle body 10 and the shaft portion 16a side of the folded portion 12, and the center axis C1 of the needle body 10 is Passes between the shaft portion 14a and the shaft portion 16a, passes through between the shaft portion 24a and the shaft portion 26a at the center axis C1 along the shaft portion 14a and the shaft portion 16a, and the center axis C2 of the needle body 20, and passes through the shaft portion 24a and the central axis C2 along the shaft portion 26a substantially coincide with each other, and the plane direction of the needle body 20 intersects the plane direction of the needle body 10 at a substantially right angle (“with respect to the plane direction of the needle body 10”). The relative positions of the needle body 10 and the needle body 20 are adjusted so that the needle body 10 and the needle body 20 intersect each other. Further, the relative position between the needle body 10 and the needle body 20 is shifted in the vertical direction to form a gap between the upper end portion of the folded portion 12 and the upper end portion of the folded portion 22.

次に、固定具30’を針体ユニット7Aに取り付ける(固定具取付け工程「加熱前ユニット形成工程」)。つまり、固定具30’は、図6示すように、筒状を呈し、熱収縮する材料により形成されたチューブ体32’と、チューブ体32’の内側の面に設けられたホットメルト接着剤層34’とを有し、この固定具30’の一方の端部から針体ユニット7Aの折り返し部12及び折り返し部22を挿入し、折り返し部12の少なくとも上側の部分が固定具30’における他方の端部から突出した状態とする。   Next, the fixing tool 30 ′ is attached to the needle body unit 7 </ b> A (fixing tool attaching process “pre-heating unit forming process”). That is, as shown in FIG. 6, the fixture 30 ′ has a tubular shape and is formed of a tube body 32 ′ formed of a heat-shrinkable material, and a hot melt adhesive layer provided on the inner surface of the tube body 32 ′. 34 ', and the folded portion 12 and the folded portion 22 of the needle body unit 7A are inserted from one end of the fixture 30', and at least the upper portion of the folded portion 12 is the other portion of the fixture 30 '. It shall be in the state which protruded from the edge part.

上記のチューブ体32’は、ポリオレフィン、ポリ塩化ビニル等の樹脂に電子線を照射し、架橋反応を引き起こすことにより、形状記憶性が付与された形状記憶樹脂から形成され、加熱されることにより軟化し、主に径方向に収縮し、放熱により硬化し、収縮した状態を維持できるものであり、また、ホットメルト接着剤層34’は、ポリアミド、ポリオレフィン等の熱可塑性樹脂により形成され、加熱されることにより、融解し、変形性、流動性が出現し、放熱後には固化して、融解時に接触していた非接触面に固着するものである。   The tube body 32 'is formed from a shape memory resin imparted with shape memory by irradiating a resin such as polyolefin or polyvinyl chloride with an electron beam to cause a crosslinking reaction, and is softened by heating. However, it is shrinkable mainly in the radial direction, cured by heat dissipation, and can maintain the shrunken state. The hot melt adhesive layer 34 'is formed of a thermoplastic resin such as polyamide or polyolefin and heated. As a result, it melts, exhibits deformability and fluidity, solidifies after heat dissipation, and adheres to the non-contact surface that was in contact with the melt.

次に、固定具30’を加熱することにより、チューブ体32’を収縮させるとともに、ホットメルト接着剤層34’を融解させる。(加熱工程)。つまり、固定具30’が取り付けられた針体ユニット7Aを電気炉等の加熱炉内に投入し、チューブ体32’が収縮を開始する温度以上で、かつ、熱変性等によって劣化してしまわない温度以下の範囲で、図4に示すように、チューブ体32’が収縮して、軸部14aと、軸部16aと、軸部24aと、軸部26aとを締付け、また、ホットメルト接着剤層34’が融解し、その融液が、チューブ体32’と、軸部14aと軸部16aと軸部24aと軸部26aとの間の隙間や、軸部14a、軸部16a、軸部24a、軸部26aどうしの間の隙間に浸透し、隙間を埋めた状態となるまでの間加熱する。   Next, the fixing member 30 ′ is heated to contract the tube body 32 ′ and melt the hot melt adhesive layer 34 ′. (Heating step). That is, the needle body unit 7A to which the fixing tool 30 ′ is attached is put into a heating furnace such as an electric furnace, and the tube body 32 ′ is not deteriorated due to heat denaturation or the like at a temperature higher than the temperature at which the tube body 32 ′ starts to shrink. In the range below the temperature, as shown in FIG. 4, the tube body 32 'contracts to fasten the shaft portion 14a, the shaft portion 16a, the shaft portion 24a, and the shaft portion 26a, and a hot melt adhesive. The layer 34 ′ is melted, and the melted liquid is the tube body 32 ′, the gap between the shaft portion 14 a and the shaft portion 16 a, the shaft portion 24 a and the shaft portion 26 a, the shaft portion 14 a, the shaft portion 16 a and the shaft portion. It penetrates into the gap between the shaft portions 26a and 24a and heats until the gap is filled.

そして、加熱炉から被加熱品を取り出し、加熱工程おける加熱を終了することにより、放熱させて、ホットメルト接着剤を固化させ(接着剤固化工程)、釣り針5Aを得る。   Then, the article to be heated is taken out from the heating furnace, and the heating in the heating process is terminated, so that the heat melt is dissipated and the hot melt adhesive is solidified (adhesive solidifying process) to obtain the fishing hook 5A.

この製造方法によれば、釣り針5Aは、図4に示すように、熱収縮したチューブ体32’が放熱後、硬化したものであるチューブ体32により、軸部14aと、軸部16aと、軸部24aと、軸部26aとが締め付けられ、チューブ体32と、軸部14aと軸部16aと軸部24aと軸部26aとの間や、軸部14a、軸部16a、軸部24a、軸部26aどうしの間には、ホットメルト接着剤層34’が融解し、再固化した接着剤34が充填されており、チューブ体32と、その内側全体が一体となって、針体10と針体20とが強固に固定されている。   According to this manufacturing method, as shown in FIG. 4, the fishing hook 5 </ b> A includes the shaft portion 14 a, the shaft portion 16 a, and the shaft by the tube body 32 that is a heat-cured tube body 32 ′ after heat dissipation. The portion 24a and the shaft portion 26a are tightened, and the tube body 32, the shaft portion 14a, the shaft portion 16a, the shaft portion 24a, the shaft portion 26a, the shaft portion 14a, the shaft portion 16a, the shaft portion 24a, the shaft Between the portions 26a, the hot melt adhesive layer 34 'is melted and filled with the re-solidified adhesive 34, and the tube body 32 and the entire inside thereof are integrated to form the needle body 10 and the needle. The body 20 is firmly fixed.

本実施例の釣り針5Aは、基本的には以上のように製造されるものであるが、加熱前ユニット形成工程において、図7に示すように、保持具Gを用いてもよい。保持具Gは、金属製平板G1(保持部)の上面に溝G2が設けられており、溝G2は、縦溝G3(第1溝部)と、縦溝G3に略直角に交差する横溝G4(第2溝部)と、縦溝G3と横溝G4との交点を中心とした凹部(非貫通穴)(略円柱状の凹部)G5と、を有し、縦溝G3と横溝G4の深さが、針体10における本体部14dの下端から軸部14aの下端までの長さ(軸部14aの軸線方向の長さ)h1及び本体部16dの下端から軸部16aの下端までの長さ(軸部16aの軸線方向の長さ)h2よりも短く形成されるとともに、針体20における本体部24dの下端から軸部24aの下端までの長さ(軸部24aの軸線方向の長さ)h3及び本体部26dの下端から軸部26aの下端までの長さ(軸部26aの軸線方向の長さ)h4よりも短く形成されている。   The fishing hook 5A of the present embodiment is basically manufactured as described above, but a holding tool G may be used as shown in FIG. The holder G is provided with a groove G2 on the upper surface of a metal flat plate G1 (holding portion). The groove G2 includes a vertical groove G3 (first groove portion) and a horizontal groove G4 (substantially perpendicular to the vertical groove G3). Second groove portion) and a recess (non-through hole) (substantially cylindrical recess) G5 centered on the intersection of the vertical groove G3 and the horizontal groove G4, and the depth of the vertical groove G3 and the horizontal groove G4 is The length from the lower end of the main body portion 14d to the lower end of the shaft portion 14a in the needle body 10 (the length in the axial direction of the shaft portion 14a) h1 and the length from the lower end of the main body portion 16d to the lower end of the shaft portion 16a (shaft portion) The length of the needle body 20 from the lower end of the main body portion 24d to the lower end of the shaft portion 24a (the length of the shaft portion 24a in the axial direction) h3 and the main body Length from the lower end of the portion 26d to the lower end of the shaft portion 26a (length in the axial direction of the shaft portion 26a) h4 Remote it is formed short.

そして、縦溝G3と横溝G4との交点を通る垂直線上に針体ユニット7Aの中心軸(針体10の中心軸C1及び針体20の中心軸C2)を合わせ、縦溝G3に針体20の本体部24dと、針体20の本体部26dを配置し、横溝G4に針体10の本体部14dと、針体10の本体部16dを配置することにより、保持具G上において、針体ユニット7Aは、その軸集合部(軸部14a、16a、24a、26aが集合している部分)を平板G1に対し略垂直とした状態で保持される。   Then, the central axes of the needle body unit 7A (the central axis C1 of the needle body 10 and the central axis C2 of the needle body 20) are aligned on a vertical line passing through the intersection of the vertical groove G3 and the horizontal groove G4, and the needle body 20 is aligned with the vertical groove G3. The main body portion 24d and the main body portion 26d of the needle body 20 are disposed, and the main body portion 14d of the needle body 10 and the main body portion 16d of the needle body 10 are disposed in the lateral groove G4. The unit 7A is held in a state in which the shaft collection portion (portion where the shaft portions 14a, 16a, 24a, and 26a are gathered) is substantially perpendicular to the flat plate G1.

つまり、針体ユニット7Aは、折り返し部22が、折り返し部12の内側における下端部またはその近傍に位置しており、つまり、針体10と針体20とは、上下方向の位置をずらしていることから、針体10の最下端部(本体部14dの最下端部と本体部16dの最下端部)は、針体20の最下端部(本体部24dの最下端部と本体部26dの最下端部)よりも上方に位置しており、そのため、例えば平面上に針体ユニット7Aを載置すると、本体部14d側または本体部16d側に傾いて、本体部14d及び本体部16dのいずれか一方と、本体部24dと、本体部26dとによる3点支持状態となるが、保持具Gを用いることにより、縦溝G3の側面によって、本体部24d及び本体部26dの側部が支持されるので、針体ユニット7Aは傾くことなく、軸集合部が略垂直な状態に保たれる。   That is, in the needle body unit 7A, the folded portion 22 is located at or near the lower end portion inside the folded portion 12, that is, the needle body 10 and the needle body 20 are displaced in the vertical direction. Therefore, the lowermost end portion of the needle body 10 (the lowermost end portion of the main body portion 14d and the lowermost end portion of the main body portion 16d) is the lowermost end portion of the needle body 20 (the lowermost end portion of the main body portion 24d and the lowermost end portion of the main body portion 26d). Therefore, for example, when the needle body unit 7A is placed on a flat surface, the needle body unit 7A is inclined toward the main body portion 14d or the main body portion 16d, and either the main body portion 14d or the main body portion 16d. On the other hand, the main body portion 24d and the main body portion 26d are in a three-point support state, but by using the holder G, the side portions of the main body portion 24d and the main body portion 26d are supported by the side surfaces of the vertical groove G3. So needle body unit 7 Without tilting the shaft set portion is kept substantially vertical state.

また、縦溝G3と横溝G4の深さに差異を設けて、縦溝G3と横溝G4とを段差状に形成してもよく、例えば、深く形成した縦溝G3に針体20を差し込み、浅く形成した横溝G4に針体10を差し込み、針体10と針体20の双方の最下端部が溝G2の底によって支持されるようにすれば、針体10と針体20との上下方向での相対位置が一定となり、製品品質が安定する。   Further, the vertical groove G3 and the horizontal groove G4 may be provided with a difference in depth, and the vertical groove G3 and the horizontal groove G4 may be formed in a step shape. For example, the needle body 20 is inserted into the deeply formed vertical groove G3 to make it shallow. If the needle body 10 is inserted into the formed lateral groove G4 and the lowermost ends of both the needle body 10 and the needle body 20 are supported by the bottom of the groove G2, the needle body 10 and the needle body 20 can be moved vertically. The relative position is constant, and the product quality is stabilized.

この保持具Gによれば、軸集合部が略垂直な状態に保たれることにより、例えば、ホットメルト接着剤層34’が、融解した際に粘性の低いものであっても、仕上がり品(釣り針5A)のチューブ体32内で接着剤34が偏在していることがない。   According to the holder G, the shaft assembly portion is maintained in a substantially vertical state. For example, even if the hot melt adhesive layer 34 ′ has a low viscosity when melted, a finished product ( The adhesive 34 is not unevenly distributed in the tube body 32 of the fishing hook 5A).

つまり、ホットメルト接着剤層34’の融液粘性が低く、また、針体ユニット7Aが傾き、チューブ体32’が傾いていると、加熱処理中のチューブ体32’内において、融液は高い位置から低い位置へと流下し、その後その状態で固化するため、チューブ体32内で接着剤34が偏在し、接着不良を生じるおそれがあるが、保持具Gの使用により、加熱処理中のチューブ体32’内において、ホットメルト接着剤層34’の融液は均等に拡散し、チューブ体32’の内側に存在する隙間に浸透し充填され、チューブ体32’の内側の隙間は、ホットメルト接着剤層34’の融液により埋め尽くされる。   That is, when the melt viscosity of the hot melt adhesive layer 34 ′ is low, and the needle body unit 7A is inclined and the tube body 32 ′ is inclined, the melt is high in the tube body 32 ′ during the heat treatment. Since the adhesive 34 is unevenly distributed in the tube body 32 because it flows down from the position to the lower position and then solidifies in that state, there is a possibility that adhesion failure may occur. In the body 32 ′, the melt of the hot melt adhesive layer 34 ′ diffuses evenly, penetrates and fills the gaps existing inside the tube body 32 ′, and the gap inside the tube body 32 ′ The adhesive layer 34 'is filled with the melt.

また、ホットメルト接着剤層34’の融液が流下し、チューブ体32’の下端部からはみ出し、チューブ体32から垂れ下がった状態で固化しても、保持具Gが凹部G5を有することから、垂れ下がった接着剤34によって、保持具Gと固定部30とが接着されてしまわない。   Further, even if the melt of the hot melt adhesive layer 34 ′ flows down, protrudes from the lower end portion of the tube body 32 ′, and solidifies in a state of hanging from the tube body 32, the holder G has the recess G5. The holder G and the fixing part 30 are not bonded by the hanging adhesive 34.

また、平行に設けられた複数の縦溝G3と、縦溝G3に直交する複数の横溝G4と、を有する保持具Gを使用すれば、一度に多くの製造中間品を取り扱うことができ、製造効率の向上を図ることができる。   In addition, if a holder G having a plurality of vertical grooves G3 provided in parallel and a plurality of horizontal grooves G4 orthogonal to the vertical grooves G3 is used, many intermediate products can be handled at a time. Efficiency can be improved.

実施例1の釣り針5Aは、以上のように構成され、また、以上のように製造され、これを使用する際には、例えば、フグ釣り用の仕掛けに用いるのであれば、図8に示すように、折り返し部12の内側の隙間S(すなわち、折り返し部12の上端部と折り返し部22の上端部の間の隙間)にハリスHの一方の端部を通し、折り返し部12に直接結び付けるか(又は、折り返し部22の内側の隙間にハリスを通して折り返し部22に結びつけてもよい)、あるいは、図示しないが、スナップ(バネ付勢により開閉可能とされているフック部)付サルカン等の連結用金具を介して、折り返し部12にハリスHの一方の端部を連結し、ハリスHの他方の端部をフグ釣り用仕掛けや鮎釣り用仕掛けにおける掛け針連結用のハリス連結部に結び付ける。また、図示しないが、例えば、ルアーに用いるのであれば、折り返し部12と、ルアー本体に設けられたアイ(フックを取り付けるための閉環状の金具)とをスプリットリング(線条材を螺旋状に巻回して形成された環状金具)を介して連結する。   The fishing hook 5A according to the first embodiment is configured as described above, and manufactured as described above. When the fishing hook 5A is used, for example, as shown in FIG. In addition, one end of Harris H is passed through the gap S inside the folded portion 12 (that is, the gap between the upper end portion of the folded portion 12 and the upper end portion of the folded portion 22) and directly connected to the folded portion 12 ( (Alternatively, Harris may be connected to the folded portion 22 through a gap inside the folded portion 22), or although not shown, a connecting bracket such as a sarkan with a snap (a hook portion that can be opened and closed by spring bias) Then, one end of Harris H is connected to the folded portion 12, and the other end of Harris H is connected to a Harris connecting portion for connecting a hook in a puff fishing device or a fishing device. Although not shown, for example, when used for a lure, the folded portion 12 and an eye (a closed ring metal fitting for attaching a hook) provided on the lure body are split rings (the wire rod is spirally formed). It connects via the annular metal fitting formed by winding.

なお、本実施例では、チューブ体32’と、チューブ体32’の内側の面に設けたホットメルト接着剤層34’と、を有する固定具30’により、固定部30を形成した釣り針5Aについて説明をしたが、ホットメルト接着剤層34’を有しない固定具(つまり、実質的にチューブ体32’)を用いてもよく、その場合は、熱収縮させた後のチューブ体32’(つまり、チューブ体32)の内側の隙間で、チューブ体32と、軸部14aと軸部16aと軸部24aと軸部26aとの隙間や、軸部14a、軸部16a、軸部24a、軸部26aどうしの隙間に接着剤を注入すればよい。   In the present embodiment, the fishing hook 5A in which the fixing portion 30 is formed by the fixing tool 30 ′ having the tube body 32 ′ and the hot melt adhesive layer 34 ′ provided on the inner surface of the tube body 32 ′. As described above, a fixing member (that is, the tube body 32 ′) that does not have the hot melt adhesive layer 34 ′ may be used. In this case, the tube body 32 ′ (that is, the tube body 32 ′ after heat shrinkage (that is, the tube body 32 ′). , The gap between the tube body 32, the shaft portion 14a, the shaft portion 16a, the shaft portion 24a, and the shaft portion 26a, the shaft portion 14a, the shaft portion 16a, the shaft portion 24a, the shaft portion. What is necessary is just to inject | pour an adhesive agent into the clearance gap between 26a.

以上のように、実施例1の釣り針5A及びその製造方法によれば、製造時の歩留まり及び作業効率を向上させ、製造コストの低減を図ることができる。つまり、針部14と針部16とを有する針体10の折り返し部12に、針部24と針部26とを有する針体20の折り返し部22を差し込むだけで、複数の針部14、16、24、26が錨形状に組まれた製造中間品(針体ユニット7A)を簡単かつ速やかに組み上げることができ、この針体ユニット7Aにおける軸集合部で、軸部14aと、軸部16aと、軸部24aと、軸部26aとが集合した軸集合部に固定具30’を取り付け、固定具30’を加熱処理することにより、熱収縮したチューブ体32’(つまり、チューブ体32)によって、軸集合部を簡単かつ確実に結束でき、さらに、チューブ体32の内側に設けられた接着剤34によって、チューブ体32と、軸集合部と、接着剤34とが一体化していることにより、上記結束状態がより確実のものとなる。よって、製造作業者の習熟度を問わず、一定の品質で、品質の安定した釣り針5Aを、歩留まり良く、かつ、効率良く得ることができる。   As described above, according to the fishing hook 5A of the first embodiment and the manufacturing method thereof, the yield and work efficiency at the time of manufacturing can be improved, and the manufacturing cost can be reduced. That is, a plurality of needle portions 14, 16 can be obtained by simply inserting the folded portion 22 of the needle body 20 having the needle portion 24 and the needle portion 26 into the folded portion 12 of the needle body 10 having the needle portion 14 and the needle portion 16. , 24, 26 can be easily and quickly assembled as a manufacturing intermediate product (needle body unit 7A). The shaft assembly portion of the needle body unit 7A includes a shaft portion 14a, a shaft portion 16a, The fixing member 30 ′ is attached to the shaft assembly portion where the shaft portion 24a and the shaft portion 26a are assembled, and the fixing device 30 ′ is heat-treated, so that the tube body 32 ′ (that is, the tube body 32) is thermally contracted. The shaft assembly portion can be easily and reliably bundled, and the tube body 32, the shaft assembly portion, and the adhesive 34 are integrated by the adhesive 34 provided inside the tube body 32. The above bundling shape There be a thing of the more reliably. Therefore, the fishing hook 5A having a constant quality and a stable quality can be obtained with good yield and efficiency regardless of the level of proficiency of the manufacturing operator.

また、針体10と針体20は同一の構成であるので、1つの構成の針体を用意すればよく、その点で製造コストの削減を図ることができる。   In addition, since the needle body 10 and the needle body 20 have the same configuration, it is only necessary to prepare a needle body having one configuration, and the manufacturing cost can be reduced in that respect.

次に、実施例2の釣り針について説明する。実施例2の釣り針5Bは、図9〜図17に示すように構成され、針体40(第1針体)と、針体40と同一の構成を有し、針体40に重ね合わせられた針体50(第2針体)と、針体40に針体50を固定し、針体40と針体50とを一体化している固定部60と、を有している。   Next, the fishing hook of Example 2 will be described. The fishing hook 5B of the second embodiment is configured as shown in FIGS. 9 to 17, has the same configuration as the needle body 40 (first needle body) and the needle body 40, and is superimposed on the needle body 40. The needle body 50 (second needle body), the needle body 50 is fixed to the needle body 40, and the fixing portion 60 that integrates the needle body 40 and the needle body 50 is provided.

針体40は、鋼鉄製(ステンレススチール製でもよい)の1本の線条材を切削加工、曲げ加工、焼き入れ処理等して形成され、図10〜図12に示すように、一般的な形状の2つの釣り針を結合したかのような構成を有している。   The needle body 40 is formed by cutting, bending, quenching, or the like from a single wire material made of steel (may be made of stainless steel). As shown in FIGS. It has a configuration as if two shaped fishing hooks were combined.

つまり、針体40は、その上端部に設けられた折り返し部42で、上記線条材の中央部を折り返し部位として該線条材を二つ折り状態にすることにより形成され、略逆U字形で下部側が上部側よりも細くなったヘアピン形状を呈し、一平面方向L1に沿って折り返し状に形成され、内側に釣り糸を通すための隙間Sが形成された折り返し部42(第1折り返し部)と、折り返し部42の一方の下端部から連設された針部44(第1針部)と、折り返し部42の他方の下端部から連設された針部46(第2針部)と、を有している。   That is, the needle body 40 is formed by folding the linear member in a folded state with the central portion of the linear member as the folded portion at the folded portion 42 provided at the upper end portion thereof, and has a substantially inverted U shape. A folded portion 42 (first folded portion) having a hairpin shape in which the lower side is thinner than the upper side, formed in a folded shape along one plane direction L1, and formed with a gap S for passing a fishing line inside; A needle portion 44 (first needle portion) provided continuously from one lower end portion of the folded portion 42 and a needle portion 46 (second needle portion) provided continuously from the other lower end portion of the folded portion 42.

次に、釣り針5Bの製造方法について説明する。まず、針体40(または針体50)に相当する長さの線分状に切断された鋼鉄製(またはステンレススチール製)の線条材の両端部を切削して針先部44c、46c(または針先部54c、56c)を形成し、次に、切削加工済みの中間品を折り曲げ、湾曲させて、針体40(または針体50)の形状に調製し、形状調製済み中間品に焼き入れ処理を施し、針体40(または針体50)を作製する。   Next, a method for manufacturing the fishing hook 5B will be described. First, both end portions of a steel (or stainless steel) wire rod cut into a line segment having a length corresponding to the needle body 40 (or the needle body 50) are cut to form needle tip portions 44c, 46c ( Alternatively, the needle tip portions 54c and 56c) are formed, and then the cut intermediate product is bent and curved to prepare the shape of the needle body 40 (or the needle body 50), and the shape adjusted intermediate product is baked. An insertion process is performed, and the needle body 40 (or the needle body 50) is produced.

次に、針体40と針体50とに、固定具60’を取り付けて加熱前ユニット7Bを形成する(加熱前ユニット形成工程)。つまり、固定具60’は、図6に示すように、筒状を呈し、熱収縮する材料により形成されたチューブ体62’と、チューブ体62’の内側の面に設けられたホットメルト接着剤層64’とを有し、図14、図15に示すように、この固定具60’の一方の端部から折り返し部42及び折り返し部52を挿入する。また、第1ユニット(針体40の折り返し部42と軸部44aと軸部46aとからなる部分)における背面側(本体部44d及び本体部46dと反対側)と、第2ユニット(針体50の折り返し部52と軸部54aと軸部56aとからなる部分)における背面側(本体部54d及び本体部56dと反対側)とを対向させて、第1ユニットと第2ユニットとを重ね、折り返し部42及び折り返し部52の少なくとも上側の部分が固定具60’における他方の端部から突出した状態とする。   Next, the fixing unit 60 ′ is attached to the needle body 40 and the needle body 50 to form the pre-heating unit 7 </ b> B (pre-heating unit forming step). That is, as shown in FIG. 6, the fixture 60 ′ has a tubular shape, a tube body 62 ′ formed of a heat-shrinkable material, and a hot melt adhesive provided on the inner surface of the tube body 62 ′. 14 and 15, the folded portion 42 and the folded portion 52 are inserted from one end of the fixture 60 ′. Further, the back side (the side opposite to the main body portion 44d and the main body portion 46d) of the first unit (the portion including the folded portion 42, the shaft portion 44a, and the shaft portion 46a) of the needle body 40, and the second unit (the needle body 50). The first unit and the second unit are overlapped with each other so that the back side (the side opposite to the main body portion 54d and the main body portion 56d) of the folded portion 52, the shaft portion 54a, and the shaft portion 56a is opposed to each other. It is assumed that at least the upper part of the part 42 and the folded part 52 protrudes from the other end of the fixture 60 ′.

なお、固定具60’は、上記固定具30’と同一の構成を有するものであるので、ここではその詳細についての説明を省略する。   Since the fixture 60 'has the same configuration as the fixture 30', a detailed description thereof is omitted here.

次に、固定具60’を加熱することにより、チューブ体62’を収縮させるとともに、ホットメルト接着剤層64’を融解させる。(加熱工程)。つまり、加熱前ユニット7Bを電気炉等の加熱炉内に投入し、チューブ体62’が収縮を開始する温度以上で、かつ、熱変性等によって劣化してしまわない温度以下の範囲で、図14に示すように、チューブ体36’が収縮して、軸部44aと、軸部46aと、軸部54aと、軸部56aとを締付け、また、ホットメルト接着剤層64’が融解し、その融液が、チューブ体62’と、軸部44aと軸部46aと軸部54aと軸部56aとの間の隙間や、軸部44a、軸部46a、軸部54a、軸部56a同士の間の隙間に浸透し、隙間を埋めた状態となるまでの間加熱する。   Next, the fixing member 60 ′ is heated to contract the tube body 62 ′ and melt the hot melt adhesive layer 64 ′.

The length of the needle body 50 from the lower end of the main body portion 54d to the lower end of the shaft portion 54a (the length of the shaft portion 54a in the axial direction) and the main body portion. Shorter than the length from the lower end of 56d to the lower end of the shaft portion 56a (the length of the shaft portion 56a in the axial direction). It is formed.

そして、この保持具Gの縦溝G3と横溝G4の交点を中心とする領域において、例えば、縦溝G3に針体40の本体部44dと、針体50の本体部54dを配置するとともに、横溝G4に針体40の本体部46dと、針体50の本体部56dを配置することにより、縦溝G3にの側面によって、本体部44dの側部と本体部54dとが支持され、横溝G4によって、本体部46dの側部と本体部56dの側部とが支持され、保持具G上において、針体40と針体50とは、軸部44aと、軸部46aと、軸部54aと、軸部56aとが平板G1に対して略垂直な状態で保持され、この状態で固定具60’を取り付ける。   And in the area | region centering on the intersection of the vertical groove G3 and the horizontal groove G4 of this holder G, while arrange | positioning the main-body part 44d of the needle body 40 and the main-body part 54d of the needle body 50 in the vertical groove G3, for example, By arranging the main body portion 46d of the needle body 40 and the main body portion 56d of the needle body 50 on G4, the side portion of the main body portion 44d and the main body portion 54d are supported by the side surfaces of the vertical groove G3, and the lateral groove G4 The side part of the main body part 46d and the side part of the main body part 56d are supported, and on the holder G, the needle body 40 and the needle body 50 include the shaft part 44a, the shaft part 46a, the shaft part 54a, The shaft portion 56a is held in a state substantially perpendicular to the flat plate G1, and the fixture 60 ′ is attached in this state.

この保持具Gによれば、加熱前ユニット7Bを保持した保持具Gを加熱炉に投入して固定具60’を加熱することにより、軸部44aと軸部46aと軸部54aと軸部56a軸を略垂直な状態に維持した状態で、固定具60’を加熱することができるため、例えば、ホットメルト接着剤層64’が、融解した際に粘性の低いものであっても、仕上がり品(釣り針5B)のチューブ体62内で接着剤64が偏在していることがない。   According to this holder G, by inserting the holder G holding the pre-heating unit 7B into the heating furnace and heating the fixture 60 ′, the shaft portion 44a, the shaft portion 46a, the shaft portion 54a, and the shaft portion 56a. Since the fixture 60 ′ can be heated with the shaft maintained in a substantially vertical state, for example, even if the hot-melt adhesive layer 64 ′ has a low viscosity when melted, it is a finished product. The adhesive 64 is not unevenly distributed in the tube body 62 of the (fishhook 5B).

つまり、ホットメルト接着剤層64’の融液粘性が低く、また、加熱前ユニット7Bが傾き、チューブ体62’が傾いていると、加熱処理中のチューブ体62’内において、融液は高い位置から低い位置へと流下し、その後その状態で固化するため、チューブ体62内で接着剤64が偏在し、接着不良を生じるおそれがあるが、保持具Gの使用により、加熱処理中のチューブ体62’内において、ホットメルト接着剤層64’の融液は均等に拡散し、チューブ体62’内に存在する隙間に浸透し充填され、チューブ体62’の内側の隙間は、ホットメルト接着剤層64’の融液により埋め尽くされる。   That is, when the melt viscosity of the hot-melt adhesive layer 64 ′ is low, and the pre-heating unit 7B is inclined and the tube body 62 ′ is inclined, the melt is high in the tube body 62 ′ during the heat treatment. Since the adhesive 64 is unevenly distributed in the tube body 62 to cause poor adhesion because it flows down from the position to the lower position and then solidifies in that state, the use of the holder G causes the tube to be heated. In the body 62 ', the melt of the hot melt adhesive layer 64' spreads evenly, penetrates and fills the gaps existing in the tube body 62 ', and the gaps inside the tube body 62' are hot melt bonded. It is filled with the melt of the agent layer 64 ′.

また、ホットメルト接着剤層64’の融液が流下し、チューブ体62’の下端部からはみ出し、チューブ体62から垂れ下がった状態で固化しても、保持具Gが凹部G5を有することから、垂れ下がった接着剤64によって、保持具Gと固定部60とが接着されてしまわない。   Further, even when the melt of the hot melt adhesive layer 64 ′ flows down, protrudes from the lower end portion of the tube body 62 ′, and solidifies in a state of hanging from the tube body 62, the holder G has the recess G5. The holder G and the fixing part 60 are not bonded to each other by the hanging adhesive 64.

また、平行に設けられた複数の縦溝G3と、縦溝G3に直交する複数の横溝G4と、を有する保持具Gを使用すれば、一度に多くの製造中間品を取り扱うことができ、製造効率の向上を図ることができる。   In addition, if a holder G having a plurality of vertical grooves G3 provided in parallel and a plurality of horizontal grooves G4 orthogonal to the vertical grooves G3 is used, many intermediate products can be handled at a time. Efficiency can be improved.

実施例2の釣り針5Bは、以上のように構成され、また、以上のように製造され、これを使用する際には、例えば、フグ釣り用の仕掛けに用いるのであれば、図17に示すように、隙間S(固定部60の上端部から上方に突出した、折り返し部42及び折り返し部52の内側の部分)にハリスHの一方の端部を通し、折り返し部12に直接結び付けるか、あるいは、図示しないが、スナップ(バネ付勢により開閉可能とされているフック部)付サルカン等の連結用金具を介して、折り返し部12にハリスHの一方の端部を連結し、ハリスHの他方の端部をフグ釣り用仕掛けや鮎釣り用仕掛けにおける掛け針連結用のハリス連結部に結び付ける。また、図示しないが、例えば、ルアーに用いるのであれば、折り返し部12と、ルアー本体に設けられたアイ(フックを取り付けるための閉環状の金具)とをスプリットリング(線条材を螺旋状に巻回して形成された環状金具)を介して連結する。   The fishhook 5B according to the second embodiment is configured as described above, and manufactured as described above. When the fishhook 5B is used, for example, if used for a device for puffer fishing, as shown in FIG. In addition, one end of Harris H is passed through the gap S (the portion inside the folded portion 42 and the folded portion 52 that protrudes upward from the upper end portion of the fixed portion 60), and is directly connected to the folded portion 12, or Although not shown in the figure, one end of Harris H is connected to the folded portion 12 via a connecting fitting such as a snap (with a hook portion that can be opened and closed by spring bias), and the other end of Harris H is connected. The end is connected to a Harris connecting portion for connecting a hook in a puffer fishing device or a kite fishing device. Although not shown, for example, when used for a lure, the folded portion 12 and an eye (a closed ring metal fitting for attaching a hook) provided on the lure body are split rings (the wire rod is spirally formed). It connects via the annular metal fitting formed by winding.

なお、本実施例では、チューブ体62’と、チューブ体62’の内側の面に設けたホットメルト接着剤層64’と、を有する固定具60’により、固定部60を形成した釣り針5Bについて説明をしたが、ホットメルト接着剤層64’を有しない固定具(つまり、実質的にチューブ体62’)を用いてもよく、その場合は、熱収縮させた後のチューブ体62’(つまり、チューブ体62)の内側の隙間で、チューブ体62と、軸部44aと軸部46aと軸部54aと軸部56aとの隙間や、軸部44a、軸部46a、軸部54a、軸部56aどうしの隙間に接着剤を注入すればよい。   In the present embodiment, the fishing hook 5B in which the fixing portion 60 is formed by the fixing tool 60 ′ having the tube body 62 ′ and the hot melt adhesive layer 64 ′ provided on the inner surface of the tube body 62 ′. Although described, a fixing device (that is, a tube body 62 ′) that does not have the hot melt adhesive layer 64 ′ may be used. In this case, the tube body 62 ′ (that is, the tube body 62 ′ after heat shrinkage) , The gap between the tube body 62, the shaft portion 44a, the shaft portion 46a, the shaft portion 54a, and the shaft portion 56a, the shaft portion 44a, the shaft portion 46a, the shaft portion 54a, and the shaft portion. What is necessary is just to inject | pour an adhesive agent into the clearance gap between 56a.

以上のように、実施例2の釣り針5B及びその製造方法によれば、製造時の歩留まり及び作業効率を向上させ、製造コストの低減を図ることができる。つまり、針部44と針部46とを有する針体40と、針部54と針部56とを有する針体50とを重ね合わせ、これに固定具60’を取り付けるだけで、複数の針部14、16、24、26が錨形状に組まれた製造中間品(加熱前ユニット7B)を簡単かつ速やかに組み上げることができる。   As described above, according to the fishing hook 5B and the manufacturing method thereof according to the second embodiment, it is possible to improve the manufacturing yield and work efficiency and to reduce the manufacturing cost. That is, the needle body 40 having the needle portion 44 and the needle portion 46 and the needle body 50 having the needle portion 54 and the needle portion 56 are overlapped, and a plurality of needle portions are simply attached thereto. An intermediate product (unit 7B before heating) in which 14, 16, 24, and 26 are assembled in a bowl shape can be easily and quickly assembled.

また、チューブ体62’が収縮したチューブ体62により、軸部44aと、軸部46aと、軸部54aと、軸部56aとが、締め付けられて結束され、チューブ体62の内側に設けられた接着剤64によって、チューブ体62と、軸部44aと、軸部46aと、軸部54aと、軸部56aと、接着剤64とが一体化していることにより、上記結束状態がより確実のものとなる。よって、製造作業者の習熟度を問わず、一定の品質で、品質の安定した釣り針5Aを、歩留まり良く、かつ、効率良く得ることができる。   In addition, the tube body 62 ′ is contracted, and the shaft portion 44 a, the shaft portion 46 a, the shaft portion 54 a, and the shaft portion 56 a are fastened and bound by the tube body 62, and provided inside the tube body 62. Since the tube body 62, the shaft portion 44a, the shaft portion 46a, the shaft portion 54a, the shaft portion 56a, and the adhesive 64 are integrated by the adhesive 64, the above-described binding state is more reliable. It becomes. Therefore, the fishing hook 5A having a constant quality and a stable quality can be obtained with good yield and efficiency regardless of the level of proficiency of the manufacturing operator.

また、針体40と針体50は同一の構成であるので、1つの構成の針体を用意すればよく、その点で製造コストの削減を図ることができる。   Further, since the needle body 40 and the needle body 50 have the same configuration, it is only necessary to prepare a needle body having one configuration, and the manufacturing cost can be reduced in that respect.
