<First Embodiment>
FIG. 1 is an explanatory view of a fishing line showing a first embodiment of the present invention, (a) is a partial view of the fishing line, and (b) is an enlarged cross-sectional view of the fishing line in the AA section of (a). It is a figure, (c) is an enlarged view of a sectional view of a fishing line in the BB section of (a), (d) and (e) are enlarged views of a transverse section of a fishing line in a modification of the first embodiment. It is.

  In FIG. 1, the fishing line is schematically illustrated for easy understanding, so the dimensional ratio is different from the actual one.

  1 (a), (b) and (c), a fishing line 1 is arranged in parallel with the core wire 2 made of fiber and the axial direction of the core wire 2, and the first side wire made of one metal strand. 3 and a second side wire 4 wound around the outer periphery of the first side wire 3 and the core wire 2 and made of four metal strands (4a, 4b, 4c and 4d). In addition, although the cross-sectional shape of the metal strand of the 2nd side wire 4 is described as an ellipse, since the 2nd side wire 4 has wound the outer periphery of the core wire 2 and the 1st side wire 3 helically, drawing The notation is described as an ellipse, and the cross section of the metal strand forming the second side line 4 is circular.

  Since the core wire 2 is formed from a fiber formed of a material described later, it is more flexible than a metal wire having the same cross-sectional area. 1 (b) and 1 (c), the outer diameter of the core wire 2 is the outer diameter of the metal wire of the first side wire 3 or the metal wire of the second side wire 4 in order to obtain flexibility as a fishing line. The outer diameter of the wires (4a, 4b, 4c and 4d) is sufficiently large. Further, in the cross sectional view of the fishing line 1 (FIGS. 1B and 1C), the cross sectional area of the core wire 2 should be larger than the sum of the cross sectional area of the first side line 3 and the cross sectional area of the second side line 4. Is preferred.

  Further, in FIG. 1A, the second side wire 4 is wound so as to be S-wound with respect to the outer periphery of the first side wire 3 and the core wire 2, but is not limited to the S-winding. The 2-side wire 4 may be wound so as to be Z-wound with respect to the outer periphery of the first side wire 3 and the core wire 2. In addition, S winding refers to a form in which the second side line 4 is wound from the lower left to the lower right direction in FIG. 1A, and Z winding refers to a form in which the second side line 4 is wound from the lower right to the upper left. Point to.

  In FIG. 1B, the first side line 3 and the second side line 4 are located on the outer periphery of the core wire 2, but as shown in FIG. 1C, the second side line 4 is It is wound so as to cover the outer periphery of the one side line 3. Further, in FIG. 1C, the strand 4a and the strand 4d of the second side wire 4 are not in contact with the outer periphery of the core wire 2, but the strand 4a and the strand of the second side wire 4 are shown. The wire 4a and the wire 4d of the second side wire 4 may be arranged so that the wire 4d contacts the outer periphery of the core wire 2.

  As described above, the fishing line 1 includes the core wire 2 made of fiber, the first side wire 3 made of one metal strand arranged in parallel to the axial direction of the core wire 2, the first side wire 3, and the core wire 2. And a second side wire 4 made of four metal strands (4a, 4b, 4c and 4d) wound around the outer periphery, so that the flexibility of the fishing line is secured by the core wire 2 made of fiber. The straightness of the fishing line is ensured by the first side line 3 to prevent the fishing line 1 from being stretched, and the second side line 4 is used to prevent the core wire 2 from being worn, thereby extending the flexibility of the fishing line 1. Both robustness can be achieved.

  Although it does not specifically limit as a material which forms the core wire 2, For example, a polyarylate fiber, a polyparaphenylene benzoxazole (PBO) fiber, an aramid fiber, an ultrahigh molecular weight polyethylene fiber, a polyimide fiber, carbon fiber is mentioned, for example. It is done. In addition, the core wire 2 of this embodiment is comprised by the one fiber core which bundled multiple fibers mentioned above.

  The material of the metal wire forming the first side wire 3 and the metal wire forming the second side wire 4 is not particularly limited, but for example, stainless steel (SUS304, SUS316, etc.), cobalt chrome Examples include alloys, nickel cobalt alloys, brass, titanium or titanium alloys, tungsten, rhenium tungsten alloys, and the like.

  The material of the metal strands forming the first side line 3 and the second side line 4 may be the same metal or different metals. Moreover, even if it is a case where it forms from a several metal strand like the 2nd side wire 4, the material of each strand may be the same metal and a different metal may be sufficient as it.

  The preferred combination of the metal strand of the first side wire 3 and the metal strand of the second side wire 4 is that the bending rigidity of the metal strand forming the first side wire 3 is the metal strand forming the second side wire 4. A combination that is greater than the bending stiffness of the wire. As a specific example of the combination, the material of the metal wire forming the first side wire 3 is rhenium tungsten alloy, and the material of the metal wire forming the second side wire 4 is stainless steel such as SUS316. Stainless steel such as SUS316 that has been subjected to strong processing (including many martensite phases that have appeared due to work hardening), and the metal that forms the second side wire 4. There is a combination of stainless steel such as SUS316, which is obtained by normal processing of the material of the wire (containing more austenite phase than martensite phase). Further, the present invention is not limited to these specific combinations, and is a combination in which the bending rigidity of the metal strand forming the first side line 3 is larger than the bending rigidity of the metal strand forming the second side line 4. I just need it.

  Thus, since the bending rigidity of the metal strand forming the first side line 3 is larger than the bending rigidity of the metal strand forming the second side line 4, the second side line positioned on the outer periphery of the first side line 3. Even when 4 rubs against the rocky place of the fishing ground, the presence of the first side line 3 can suppress the curl deformation of the second side line 4, thereby improving the robustness of the fishing line 1 and the straightness of the fishing line 1. Therefore, the sensitivity of the fishing line 1 can be prevented from being lowered.

  Further, as a method for producing the fishing line 1, the first side wire 3 is arranged so as to be parallel to the axial direction of the core wire 2, and then the second side wire 4 is arranged on the outer periphery of the first side wire 3 and the core wire 2 using a twisting machine or the like. The fishing line 1 can be produced by winding the. Moreover, you may produce the fishing line 1 using a well-known technique, without being limited to this.

Next, a modification of the first embodiment will be described.
FIG.1 (d) is the figure of the cross-sectional view of the fishing line 11 which showed the modification of 1st Embodiment. In FIG.1 (b), although the outer diameter of the metal strand of the 1st side wire 3 and the 2nd side wire 4 was the same, it is not limited to this, The metal of the 1st side wire 3 and the 2nd side wire 4 The outer diameters of the wires may be different. Preferably, from the relationship of the bending rigidity of the metal strands of the first side line 3 and the second side line 4 described above, the metal of the first side line 3 and the second side line 4 as shown in FIG. The outer diameters of the strands are the same, or as shown in FIG. 1 (d), the outer diameter of the metal strand of the first side wire 13 is the second side wire 14 (14a, 14b, 14c and 14d) larger than the outer diameter of the metal wire.

  Since the outer diameter of the metal strand of the first side wire 13 is larger than the outer diameter of the metal strand of the second side wire 14, the bending rigidity of the metal strand of the first side wire 13 is further increased, and the first The curling deformation of the two-side line 14 can be further prevented, and the robustness and sensitivity of the fishing line 11 can be improved.

  Further, in FIG. 1B, the four metal wires forming the second side line 4 are arranged in parallel, but the second side line 14 is arranged as shown in FIG. The four metal strands to be formed may be arranged in parallel (2 each) (14a and 14b and 14c and 14d). In this case, as a preferable arrangement form of the second side line 14, the metal strands of the second side line 14 are arranged point-symmetrically with respect to the center point O of the core wire 2 as shown in FIG. It is preferred that By arranging the second side lines 14 symmetrically, even if the metal strands forming one of the second side lines, for example, 14a and 14b rub against the rocky place of the fishing ground, the other second The metal wires 14c and 14d and the first side wire 13 forming the side wire 14 can prevent the fishing line 11 from being curled by the metal wires 14a and 14d of the second side wire 14.

  Further, the metal strands 14a and 14b and 14c and 14d forming the second side wire 14 described in FIG. 1D are wound in the same direction with respect to the outer periphery of the core wire 2 and the first side wire 13. However, the metal strands 14c and 14d can be wound as a third side wire (not shown) in the opposite direction to the metal strands 14a and 14b of the second side wire 14.

FIG.1 (e) is the figure of the cross-sectional view of the fishing line 21 which showed another modification of 1st Embodiment.
In FIG. 1 (b), the four metal strands forming the second side wire 4 are arranged without a gap, but the present invention is not limited to this and is described in FIG. 1 (e). As shown, the four metal wires (24a, 24b, 24c and 24d) forming the second side wire 24 may be arranged to have a gap C, and the gap C is constant. It does not have to be constant.

  Thus, since the metal strands forming the second side line 24 are arranged so as to have a gap C, even when the fishing line 21 is bent, the metal strands forming the second side line 24 are arranged. Since the strands are not in contact with each other, the flexibility of the fishing line 21 can be improved.

Second Embodiment
Next, the fishing line 31 of the second embodiment will be described with reference to FIG. 2A focusing on differences from the first embodiment. Portions common to the first embodiment are denoted by the same reference numerals in the drawing.
Note that FIG. 2A schematically shows the fishing line 31 for easy understanding, so the overall dimensions are different from the actual dimensions.

  In FIG. 2A, the fishing line 31 is first in that the first side line 23 arranged in parallel with the axial direction of the core wire 2 is formed of two metal strands (23a and 23b). Different from the embodiment.

  Thus, since the 1st side line 23 arrange | positioned in parallel with respect to the axial direction of the core wire 2 is formed with the strand of two metals, while improving the straightness of the fishing line 31 further, 2nd It is possible to further prevent curl deformation that occurs when the side line 4 comes into contact with the rocky place of the fishing ground.

  In addition, when arranging the metal strand which forms the 1st side line 23, it is necessary to set in the range which does not affect the softness | flexibility of the fishing line 31, and 2-4 are preferable.

Next, a modification of the second embodiment will be described.
FIG. 2B is a cross-sectional view of the fishing line 41 showing a modification of the second embodiment. In FIG. 2 (a), the first side wires 23 are arranged in parallel to the outer periphery of the core wire 2. However, as shown in FIG. 2 (b), the metal strands 33a forming the first side wires 33 are provided. And 33b can be arranged so as to be point-symmetric with respect to the center point O of the core wire 2.

  Since the first side line 33 is arranged point-symmetrically with respect to the center point O of the core wire 2 in this way, the first side line 33 is located on both sides of the core wire 2 and the core wire 2 is supported from both sides. The straightness of the fishing line 41 can be improved.

  Moreover, the fishing line 51 which is another modification of 2nd Embodiment is described in FIG.2 (c). The fishing line 51 has four metal wires (43a, 43b, 43c and 43d) forming the first side wire 43, and four metal wires (34a, 34b, 34c) forming the second side wire 34. And 34d). The four metal strands of the first side wire 43 are arranged symmetrically with respect to the center point O of the core wire 2, and one of the metal strands of the metal strands of the second side wire 34. (34a and 34b) and the other metal strand group (34c and 34d) are arranged symmetrically with respect to the center point O of the core wire 2.

  In this way, the metal strands forming the first side wires 43 and the metal strands forming the second side wires 34 are arranged so as to be point-symmetric with respect to the center point O of the core wire 2. Since the first side line 43 is positioned on the four side surfaces of the core wire 2, the straightness of the fishing line 51 is improved, and the metal strands (34a and 34b) forming one second side line 34 are fishing grounds. Even when it is in contact with a rocky place, the metal strands (34c and 34d) forming the first side line 43 and the other second side line 34 prevent the curl deformation of the one second side line 34. As a result, the fastness of the fishing line 51 can be improved.

  Although not shown, among the metal strands forming the second side wire 34, the strand 34b is disposed between the metal strand 43b and the strand 43c of the first side wire 43, The strand 34d is arranged between the metal strand 43a and the strand 43d of the first side wire 43, and the metal strands of the second side wire are point-symmetric with respect to the center point O of the core wire 2. It can also be arranged.

<Third Embodiment>
Next, the fishing line 61 of the third embodiment will be described with reference to FIG. 3A focusing on differences from the first embodiment. Portions common to the first embodiment and the second embodiment are denoted by the same reference numerals in the drawing.
3A schematically shows the fishing line 61 for easy understanding, the overall dimensions are different from the actual dimensions.

  3A, the fishing line 61 has three metal wires (53a, 53b, and 53c) that form the first side line 53, and the metal wire that forms the second side wire 44 of the fishing line 61. It has a configuration of two (44a and 44b). As apparent from FIG. 3A, the fishing line 61 is first in that the number of metal strands forming the first side line 53 is greater than the number of metal strands forming the second side line 44. Different from the embodiment.

Thus, in the fishing line 61 of the present embodiment, since the number of strands forming the first side line 53 is larger than the number of metal strands forming the second side line 44, the straightness of the fishing line 61 is secured. Even if the second side line 44 is in contact with the rocky place of the fishing ground, the first side line 53 can effectively prevent the second side line 44 from being curled.
In the present embodiment, the second side wire 44 is formed of two metal strands (44a and 44b), but the second side wire 44 may be formed of one metal strand.

  Moreover, the fishing line 71 which is a modification of 3rd Embodiment is described in FIG.3 (b). As shown in FIG. 3B, there are four metal wires (43a, 43b, 43c and 43d) forming the first side line 43 of the fishing line 71, and the second side line 54 of the fishing line 71 is The number of metal strands to be formed is two (54a and 54b). Further, four metal strands forming the first side wire 43 and two metal strands forming the second side wire 54 are arranged point-symmetrically with respect to the center point O of the core wire 2. .

  In this way, the metal strands forming the first side lines 43 and the metal strands forming the second side lines 54 are arranged so as to be point-symmetric with respect to the center point O of the core wire 2. Since the first side line 43 is located on the four side surfaces of the core wire 2, the straightness of the fishing line 71 is improved, and the metal strand (54a) forming one second side line 54 is a rocky place of the fishing ground. Even if the first side wire 43 and the metal wire (54d) forming the other second side wire 54 can prevent curl deformation of the one second side wire 54, Thus, the fastness of the fishing line 71 can be improved.

<Fourth embodiment>
Next, the fishing line 81 according to the fourth embodiment will be described with reference to FIG. 4 focusing on differences from the first embodiment. Portions common to the first embodiment and other embodiments are denoted by the same reference numerals in the drawings.

  4 (a) and 4 (b), the fishing line 81 is different from that of the first embodiment in that the cross section of the metal strand forming the first side line 63 is rectangular. In addition, the first side line 63 is disposed such that the long side LS1 portion of the rectangular cross section of the metal strand forming the first side line 63 faces the outer periphery OC of the fishing line.

  As described above, the shape of the cross section of the metal strand forming the first side line 63 is a rectangular cross section, and the long side LS1 forming the rectangular cross section faces the outer periphery OC of the fishing line. Since the outer diameter of the fishing line 81 is reduced while securing the properties, the fishing line 81 can be prevented from dandruff.

  Further, since the first side wire 63 is in surface contact with the core wire 2, a frictional force is generated between the first side wire 63 and the core wire 2, and the first side wire 63 slides on the outer surface of the core wire 2. Accordingly, the fishing line 81 is more difficult to extend, and the sensitivity of the fishing line 81 can be improved.

  In order to effectively prevent the thread dandruff, the thickness of the rectangular cross section of the metal strand forming the first side wire 63 is smaller than the outer diameter of the metal strand forming the second side wire 4. It is preferable to do so. Thus, since the thickness of the rectangular cross section of the metal wire forming the first side wire 63 is smaller than the outer diameter of the metal wire forming the second side wire 4, the outer diameter of the fishing line 63 is reduced. And can further prevent thread dander.

  Moreover, the fishing line 91 is described in FIG.4 (c) as a modification of 4th Embodiment. As shown in FIG. 4C, the second side line 64 of the fishing line 91 is formed by four rectangular metal wires (64a, 64b, 64c and 64d), and has a rectangular cross section. The long side LS2 to be formed faces the outer periphery OC of the fishing line 91. As described above, the metal strand forming the second side wire 64 is a strand having a rectangular cross section, and the long side LS2 forming the rectangular cross section is opposed to the outer periphery OC of the fishing line 91 as described above. Since the outer diameter of the fishing line 91 is reduced while securing the robustness of the fishing line 91, the fishing line 91 can be prevented from dandruff.

  5 (a) and 5 (b), the fishing line 101 has a first side wire 63 formed from one metal wire having a rectangular cross section, and a second side wire 64 having a metal wire 4 having a rectangular cross section. It is different from the fourth embodiment in that it is formed from books (64a, 64b, 64c and 64d). Further, as in the fourth embodiment and the modification thereof, the long side LS1 of the rectangular cross section of the first side line 63 opposes the outer periphery OC of the fishing line 101, and further, the metal that forms the second side line 64 is far away. Of the rectangular cross section, the long side LS2 is opposed to the outer periphery OC of the fishing line 101.

  Further, when the first side line 63 and the second side line 64 are in contact with each other, the long side of the rectangular cross section of the first side line 63 forms the second side line 64 as shown in FIG. It arrange | positions so that the long side of the rectangular cross section of the strand 64c may be in surface contact among the metallic strands.

  Thus, the shape of the cross section of the metal strand which forms the 1st side line 63 of the fishing line 101 and the metal strand which forms the 2nd side line 64 is a rectangular cross section, and long side LS1 and LS2 which form a rectangular cross section Is opposed to the outer periphery OC of the fishing line 101, so that the outer diameter of the fishing line 101 is reduced to further prevent the dandruff, and the core wire 2, the first side line 63, the first side line 63, and the second side line 64 Since the surfaces are in contact with each other, the fastness of the fishing line 101 can be further improved by dispersing the tension relating to the fishing line 101 to the core wire 2, the first side line 63, and the second side line 64.

The resin layer 5 covers the outer periphery of the core wire 2 and at the same time embeds the first side line 3 and the second side line 4 so that the cross-sectional view of the fishing line 111 is circular.

  Thus, since the fishing line 111 includes the resin layer 5 that covers the outer periphery of the core wire 2 and in which the first side line 3 and the second side line 4 are embedded, the first side line 3 and the second side line 4 are Since it does not slip with respect to the outer periphery of the core wire 2, the sensitivity of the fishing line 111 is improved, and the second side line is prevented from coming into direct contact with the rocky place of the fishing ground, so that the robustness of the fishing line 111 is further improved. be able to.

  The material for forming the resin layer 5 is not particularly limited, but various elastomers such as polyethylene, polypropylene, polyamide, polyester, polyurethane and polyamide elastomer, fluororesins such as polytetrafluoroethylene, polyimide and polyamide An imide etc. are mentioned.

  As a method for forming the resin layer 5 of the fishing line 111, extrusion molding or dissolving the resin in a solvent to prepare a resin solution, and the fishing line 111 (that is, the fishing line 1) not having the resin layer 5 is used as the resin. The fishing line 111 can be obtained by dipping in a solution of Moreover, you may produce the fishing line 111 using a well-known technique, without being limited to these methods.

  Further, as described above, the fishing line 111 illustrated in FIG. 6A has the outer periphery of the first side line 3 and the second side line 4 embedded in the resin layer 5, and the entire crossing of the fishing line 111 including the resin layer 5. Although the surface view is circular, as shown in FIG. 1C, the resin layer 5 is formed in consideration of the portion covering the outer periphery of the second side line 4 that covers the outer periphery of the first side line 3. It is also possible to embed the outer periphery of the second side line 4 covering the outer periphery of the first side line 3 and further provide a circular cross-sectional view of the entire fishing line 111 including the resin layer 5 (not shown).

  Moreover, like the fishing line 121 which is a modification of 6th Embodiment described in FIG.6 (b), the resin layer 15 remains so that the outline of the core wire 2, the 1st side line 3, and the 2nd side line 4 may remain. Is provided. Thus, by applying the resin layer 15 so that the outlines of the core wire 2, the first side line 3, and the second side line 4 remain, an increase in the outer diameter of the fishing line 121 due to the resin layer 15 can be suppressed. The yarn dander can be further prevented.

  Moreover, you may provide the resin layer 25 on the outer periphery of the fishing line 101 of 5th Embodiment like the fishing line 131 which is another modification of 6th Embodiment described in FIG.6 (c). By providing the resin layer 25 on the fishing line 101 of the fifth embodiment, the fastness of the fishing line 131 can be further improved.

  Further, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art within the technical idea of the present invention.

  For example, among the four metal strands forming the second side wire 4 of the fishing line 1 of the first embodiment, a strand having a rectangular cross section may be used in part. Moreover, the cross-sectional shape of the metal strand which forms the 1st side line 3 and the 2nd side line 4 of the fishing line 1 of 1st Embodiment may be an elliptical cross section.

  Moreover, the cross-sectional shape of the metal strand which forms the 1st side line 63 and the 2nd side line 64 of the fishing line 101 of 5th Embodiment may be a strand by which the vertex of the rectangular cross section was R chamfered. Even when the vertex of the rectangular cross section of the metal strand forming the first side line 63 and the second side line 64 is in contact with the core wire 2 by using the strand whose chamfered corner is used for the vertex of the rectangular cross section The core wire 2 is not damaged, and the fastness of the fishing line 101 can be ensured.

  Moreover, in each embodiment, although the core wire 2 was described as one fiber core, it is good also as the core wire 2 which twisted the several fiber core. By twisting the core wire 2 with a plurality of fiber cores, the flexibility of the core wire 2 can be increased.
