Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional lure, since the core member has a rod shape, there is a risk that the main body portion slips off the core member when the prey clings to the main body portion.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a lure capable of preventing displacement of the main body portion.

Means for Solving the Problems

[0006] The lure according to the present invention includes a fishing line fixing portion connected to a fishing line on the proximal end side, a rigid core member having a rod shape, a main body portion provided on the proximal end side of the core member and having a cylindrical shape and serving as a portion where the prey clings, and a fishing hook attached to the distal end side of the core member. The core member includes a displacement prevention portion that prevents displacement of the main body portion by expanding the diameter toward the main body portion between the main body portion and the fishing hook, and is characterized in that.

[0007] According to the present invention, a displacement prevention part is provided between the main body and the hook, thereby restricting the movement of the main body toward the hook. Therefore, even if a downward force is applied when the catch is lifted due to the weight of the catch and the force applied when lifting it, the main body can be prevented from shifting toward the hook.

[0008] Furthermore, it is preferable that the main body portion is provided with a covering member that covers the outer circumferential surface.

[0009] According to the present invention, the covering member can be given color, pattern, etc. Furthermore, it is possible to prevent the main body from being bitten and damaged by prey.

[0010] Furthermore, it is preferable that the core material portion is provided with a displacement prevention portion between the fishing line fixing portion and the main body portion, which expands in diameter toward the main body portion to prevent displacement of the main body portion.

[0011] According to the present invention, since a displacement prevention part is provided between the fishing line fixing part and the main body part, it is possible to prevent the main body part from shifting towards the base end.

[0012] Furthermore, it is preferable that the core material portion has a higher specific gravity than the main body portion.

[0013] According to the present invention, since the core material is heavier than the main body, the hook side can be oriented downwards in the water. This makes it easier for the catch to get caught on the hook when it is pulled up.

[0014] Furthermore, it is preferable that an artificial eye is attached to the displacement prevention part.

[0015] According to the present invention, since the core material is rigid, it is possible to easily attach an artificial eye.

[0016] Furthermore, it is preferable that a recess is formed on the outer circumferential surface of the displacement prevention portion, and that the artificial eye is positioned in the recess.

[0017] According to the present invention, the amount by which the artificial eye protrudes from the outer peripheral surface of the displacement prevention portion can be reduced.

[0018] Further, it is preferable that the artificial eye has a substantially hemispherical shape, the concave portion has a flat bottom, and the artificial eye is disposed on the bottom.

[0019] According to the present invention, since the artificial eye can be disposed on the flat bottom, the adhesion of the artificial eye can be improved.

[0020] Further, it is preferable that the height dimension of the artificial eye is smaller than the depth dimension of the concave portion. According to the present invention, since the artificial eye does not protrude outside the outer peripheral surface of the displacement prevention portion, it is possible to make the artificial eye difficult to fall off.

[0021] Further, it is preferable that the artificial eye is a weight member. According to the present invention, since there is no need to separately prepare a weight, the number of parts can be reduced.

Effects of the Invention

[0022] According to the present invention, it is possible to provide a lure that can prevent displacement of the main body portion.

Modes for Carrying Out the Invention

[0024] <First Embodiment> Embodiments of the present invention will be described below with reference to the attached drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant explanations are omitted as appropriate.

[0025] The lure 100 according to this embodiment is a fishing lure mainly for catching squid, octopus, and the like. As shown in Figure 1, the lure 100 according to this embodiment comprises a core material part 1, a main body part 2, a covering member 3, a fishing hook 4, and an artificial eye 5.

[0026] As shown in Figures 1 and 2, the core material 1 is a rigid member in the shape of a rod. The core material 1 is formed of, for example, a thermoplastic resin (such as polycarbonate). The core material 1 can be formed, for example, by injection molding. The core material 1 has a higher specific gravity than the main body 2. The core material 1 comprises a shaft portion 10, a fishing line fixing portion 11, a displacement prevention portion 20, and a fishing hook fixing portion 30. In other words, the core material 1 is formed in a continuous sequence from the base end to the tip end, with the fishing line fixing portion 11, shaft portion 10, displacement prevention portion 20, and fishing hook fixing portion 30 in that order. In the following description, the fishing line fixing portion 11 side (left side in Figure 2) will be referred to as the base end, and the fishing hook fixing portion 30 side (right side in Figure 2) as the tip end.

[0027] As shown in Figure 2, the shaft portion 10 is a slender cylindrical shape and is the part to which the main body portion 2 is attached. The fishing line fixing portion 11 is provided continuously on the base end side of the shaft portion 10 and is the part to which the fishing line (not shown) is attached. The fishing line fixing portion 11 comprises a fishing line fixing main body portion 12 and a tapered portion 14. The fishing line fixing main body portion 12 is formed coaxially with the shaft portion 10 and is a cylindrical part. The fishing line fixing main body portion 12 has a circular through hole 13 for inserting the fishing line. The tapered portion 14 is formed continuously from the tip side of the fishing line fixing main body portion 12 and widens in diameter toward the main body portion 2. The tapered portion 14 is the part that restricts the movement of the main body portion 2 toward the base end side and fixes the end of the covering member 3, which will be described later.

[0028] As shown in Figure 3, the displacement prevention portion 20 is solid and frustoconical in shape, widening in diameter towards the main body portion 2. The displacement prevention portion 20 is formed between the shaft portion 10 and the fishhook fixing portion 30. The outer diameter of the base end of the displacement prevention portion 20 is approximately the same as, or slightly larger than, the outer diameter of the tip end of the main body portion 2. In other words, the outer diameter of the base end of the displacement prevention portion 20 is set such that the surface of the covering member 3 and the outer circumferential surface of the displacement prevention portion 20 are flush when the covering member 3 is attached to the main body portion 2. The displacement prevention portion 20 has a contact surface 21 that abuts against the main body portion 2 and a recess 22 in which the artificial eye 5 is placed.

[0029] The contact surface 21 is a plane formed on the base end side of the displacement prevention part 20 and is perpendicular to the axis of the core material part 1. The contact surface 21 contacts the end (tip side) of the main body part 2, thereby restricting the movement of the main body part 2 toward the tip side.

[0030] Recesses 22, 22 are formed on both sides of the displacement prevention section 20 in the width direction. That is, the recesses 22, 22 are positioned opposite each other. As shown in Figure 3, the recesses 22, 22 are grooves that are recessed on the axis side and into which the artificial eye 5 is attached. In this embodiment, two recesses 22 are formed, but there may be one or three or more. The recess 22 has a bottom portion 22a which is a flat surface into which the artificial eye 5 is placed. In this embodiment, the bottom portions 22a on both sides are inclined so that they become closer to each other as they move towards the tip. The bottom portion 22a may also be a flat surface parallel to the axis portion 10 without being inclined. The depth dimension of the recess 22 can be set as appropriate, but in this embodiment it is formed to be greater than the height dimension of the artificial eye 5.

[0031] The hook fixing part 30 is rod-shaped and is formed continuously with the tip of the displacement prevention part 20. Two hooks 4, 4 are attached to the hook fixing part 30. The number of hooks attached to the hook fixing part 30 may be one or three or more. The number and shape of the hooks 4 can be set as appropriate according to the application.

[0032] As shown in Figure 3, the main body 2 is a tubular soft member. The main body 2 is made of an elastic material such as an elastomer. In this embodiment, the main body 2 is made of an elastomer, but it may be made of any other material that has a specific gravity lower than water. The lure 100 is shaped to resemble a squid overall. Since the main body 2 is the part that prey grabs onto, it is preferable that it be made of a flexible material with elasticity that does not cause discomfort to the prey. The main body 2 can be attached to the shaft 10 of the core material 1 by inserting the core material 1 through the tubular hollow part of the main body 2. The diameter is largest in the central part (belly part) of the main body 2 and gradually decreases towards both ends of the main body 2. The base end of the main body 2 abuts against the tapered part 14 of the fishing line fixing part 11, and the tip end of the main body 2 abuts against the contact surface 21 of the displacement prevention part 20. The main body 2 may also be made of a hard material.

[0033] The covering member 3 is a member that covers the outer circumferential surface of the main body 2. The material of the covering member 3 can be set as appropriate, but in this embodiment, a cloth material is used. The covering member 3 can be formed by wrapping a single piece of cloth material around the main body 2, welding the ends of the cloth material together, and applying adhesive to the welded portion. The base end of the covering member 3 is attached so as to cover a part of the tapered portion 14, and its surface is wrapped and secured with thread material (not shown). As shown in Figure 4, the tip portion 3a of the covering member 3 is sandwiched between the main body 2 and the contact surface 21, and the tip portion 3a is attached to the contact surface 21 by adhesive. The covering member 3 may also be designed with colors, patterns, bumps, etc. to appeal to squid and octopuses. The covering member 3 may be omitted.

[0034] The artificial eye 5 is a component provided to enhance the appeal to prey, and is a roughly hemispherical component that mimics the eye of a squid. The artificial eye 5 is bonded to the bottom 22a of the recess 22. The height dimension of the artificial eye 5 can be set as appropriate, but in this embodiment it is smaller than the depth dimension of the recess 22. In other words, the artificial eye 5 is sized so that it does not protrude outward from the outer surface of the displacement prevention part 20. The shape of the artificial eye 5 may be, for example, spherical, oblate, or the like. The artificial eye 5 may also be a weight component.

[0035] As described above, the lure 100 of this embodiment is equipped with a displacement prevention part 20 between the main body 2 and the hook 4, thereby restricting the movement of the main body 2 toward the hook 4. In other words, even if a downward force acts on the main body 2 due to the weight of the catch and the force of catching it when a squid or other prey is caught, the main body 2 can be prevented from shifting toward the hook 4. Furthermore, damage to the covering member 3 due to displacement of the main body 2 can be prevented.

[0036] Furthermore, since the main body 2 is equipped with a covering member 3 that covers its outer periphery, the covering member 3 can be given color, patterns, etc. Also, by covering the main body 2 with the covering member 3, it is possible to prevent the main body 2 from being bitten and damaged by prey.

[0037] Furthermore, the core material 1 has a higher specific gravity than the main body 2. In other words, because the core material 1 is heavier than the main body 2, the hook 4 can be positioned downwards in the water. This makes it easier for the catch to get caught on the hook 4 when it is pulled up.

[0038] Furthermore, the artificial eye 5 is attached to the displacement prevention part 20. In other words, by attaching the artificial eye 5 to the rigid displacement prevention part 20, it is possible to attach the artificial eye 5 more easily than with the flexible main body part 2.

[0039] Furthermore, a recess 22 is formed on the outer surface of the displacement prevention part 20, which is recessed toward the axis, and the artificial eye 5 is positioned in the recess 22. By attaching the artificial eye 5 to the recess 22, the amount of protrusion from the outer surface of the displacement prevention part 20 can be reduced. This allows for the use of a larger artificial eye 5, which can visually appeal to prey and prevent the artificial eye 5 from falling off.

[0040] Furthermore, the artificial eye 5 is approximately hemispherical in shape, and the recess 22 has a flat bottom 22a, on which the artificial eye 5 is positioned. This allows the artificial eye 5 to be positioned on the flat bottom 22a, thereby improving the adhesion of the artificial eye 5.

[0041] Furthermore, the height dimension of the artificial eye 5 is formed to be smaller than the depth dimension of the recess 22. This prevents the artificial eye 5 from protruding beyond the outer surface of the displacement prevention part 20, making it less likely for the artificial eye 5 to fall out.

[0042] Furthermore, by using the artificial eye 5 as a weight component, there is no need to prepare a separate weight for the mechanism, thus reducing the number of parts.

[0043] Furthermore, the tip 3a of the covering member 3 is sandwiched between the main body 2 and the contact surface 21, and the tip 3a is attached to the contact surface 21 by adhesive. This prevents the covering member 3 from peeling off from the main body 2. In addition, this makes the boundary between the covering member 3 and the displacement prevention part 20 smooth and without any steps, which reduces the discomfort felt when prey latches onto the main body 2.

[0044] <Second Embodiment> Next, the lure according to the second embodiment will be described. As shown in Figure 5, the second embodiment differs from the first embodiment in that a displacement prevention part is also formed on the base end side of the main body. In other words, the lure 200 comprises a core material part 201, a main body part 2, a covering member 3, a fishhook 4, and an artificial eye 5. The main body part 2, covering member 3, fishhook 4, and artificial eye 5 are the same as in the first embodiment, so their description will be omitted. The second embodiment will be described focusing on the differences from the first embodiment.

[0045] As shown in Figure 5, the core material portion 201 comprises a shaft portion 10, a fishing line fixing portion 11, displacement prevention portions 20, 40, and a fishing hook fixing portion 30. In other words, in addition to the configuration of the first embodiment, the core material portion 201 includes a displacement prevention portion 40 that expands in diameter toward the main body portion 2 between the fishing line fixing portion 11 and the main body portion 2. The shape of the displacement prevention portion 40 is the same as that of the displacement prevention portion 20 described above, and it has a contact surface 41 that abuts against the tip end of the main body portion 2 and a recess 22 on which the artificial eye 5 is placed. The outer diameter of the tip end of the displacement prevention portion 40 is approximately the same as or slightly larger than the outer diameter of the base end of the main body portion 2. In other words, the outer diameter of the tip end of the displacement prevention portion 40 is set such that the outer surface of the outer surface of the covering member 3 and the outer surface of the displacement prevention portion 40 are flush when the covering member 3 is attached to the main body portion 2.

[0046] In this embodiment, the recess 22 is provided only in the displacement prevention portion 40, but it is sufficient if it is provided in at least one of the displacement prevention portions 20 and 40.

[0047] The lure 200 of this embodiment, as described above, can achieve the same effects as the first embodiment. Furthermore, the core material portion 201 is provided with a displacement prevention portion 40 that expands in diameter toward the main body portion 2 between the fishing line fixing portion 11 and the main body portion 2, thereby preventing displacement of the main body portion 2. This prevents the main body portion 2 from shifting not only toward the tip but also toward the base end, allowing the main body portion 2 to be fixed more firmly.

[0048] Furthermore, while the tapered portion 14 can restrict the movement of the main body portion 2 toward the base end to some extent, the outer diameter of the end of the displacement prevention portion 40 in this embodiment is formed to be approximately the same as the outer diameter of the end of the main body portion 2 including the covering member 3. This makes it possible to more effectively prevent the main body portion 2 from shifting toward the base end. In addition, since the surface of the covering member 3 and the outer circumferential surface of the displacement prevention portion 40 are flush, unnatural steps can be reduced, which can reduce the discomfort caused when prey latches onto it.

[0049] While embodiments of the present invention have been described above, the design can be modified as appropriate without violating the spirit of the invention. For example, in this embodiment, a flat bottom surface 22a is provided in the recess 22, but a configuration in which a small groove or the like is provided in the bottom 22a to improve the adhesive strength due to the anchoring effect is also possible.

[0050] Furthermore, although a configuration in which the tip 3a of the covering member 3 is sandwiched and fixed between the main body 2 and the displacement prevention part 20 has been described, the covering member 3 may also be fixed to the outer surface of the displacement prevention part 20 by adhesive or by winding thread, etc., without being sandwiched.
