Description

Technical Field

[0001] The present invention relates to fishing bait. Background Art

[0002] Conventionally, there has been a problem with fishing lures such as baitwood becoming lodged on the seabed due to snagging on rocks, seaweed, or the bottom of nets. Furthermore, conventional fishing lures, such as those described in Patent Document 1, have a technique in which a component such as a hook breaks when the strength of the lure body (main body) falls below a predetermined value.

[0003] By breaking the attachment member in this manner, even when the bait becomes stuck on the bottom, the hook and the body can be separated, and the body can be recovered without remaining on the seabed.

[0004] Patent Document 1: Japanese Patent No. 7162036.

[0005] However, in conventional fishing lures with a structure where the hook and other attachment components break from the main body, as shown in Patent Document 1, the breaking strength of the attachment components must be less than the strength of the fishing line. Consequently, this makes it more difficult to catch large fish compared to conventional fishing lures, and there is room for improvement in this regard. Summary of the Invention

[0006] The present invention has been made in view of such circumstances, and an object thereof is to release the body of the lure from the stuck state while ensuring the strength of the engagement portion between the mounting member and the body.

[0007] (1) A first embodiment of the fishing lure of the present invention is characterized in that it comprises: an assembly component having an engaging portion engaged with a main body, and an engaged portion in the main body covering the engaging portion, wherein at least one of the engaging portion of the assembly component and the engaged portion of the main body is formed of a material that can be decomposed in water.

[0008] According to the first embodiment of the fishing lure of the present invention, at least one of the engaging portion of a mounting component, such as a hook eye or line eye, attached to the main body of the lure and the engaged portion of the main body engaged therewith is formed of a water-degradable material such as a biodegradable resin. Therefore, when the lure is continuously immersed in water (e.g., in the sea), the portion made of the water-degradable material decomposes. For example, if the water-degradable material is a biodegradable resin, biodegradation occurs. Consequently, the engagement between the engaging portion and the engaged portion is released. Even if the lure becomes stuck, the decomposition of at least one of the engaging portion and the engaged portion separates the main body and the mounting component, allowing the lure to be released from the stuck state.

[0009] Furthermore, this lure utilizes a structure that utilizes a decomposable portion to separate the main body from the mounting member that is stuck in the bottom. This differs from conventional structures that set the mounting member's breakage strength to be less than the strength of the fishing line, and then recover the main body by breaking the mounting member when it becomes stuck. Therefore, this lure maintains sufficient strength at the point where the mounting member engages the main body, enabling the same catching of large fish as conventional lures without damaging the mounting member.

[0010] (2) According to claim 2 of the present invention, in the lure of claim 1, a gap communicating with the surface of the main body is preferably present between the engaging portion and the engaged portion.

[0011] In this case, if the bait remains in the water (in the sea), water will seep from the surface of the body into the gap between the engaging portion and the engaged portion, causing the disassembly of at least one of the engaging portion and the engaged portion to proceed. As a result, the gap between the engaged portion and the engaging portion becomes larger, causing looseness, making it easier for the engaging portion and the engaged portion to be released.

[0012] (3) According to the third aspect of the present invention, in the fishing lure of the first or second aspect, the attachment member is preferably at least one of an eye of the line, an eye of the hook, and a hook.

[0013] In this case, the engaging portion of at least one of the eye of the line, the eye of the hook, and the hook, or the engaged portion of the main body engaged therewith, disintegrates in water (in the sea), allowing it to be separated from the main body in water (in the sea). This allows the bait to be released from the stuck state even if, for example, a weight installed on the line side becomes stuck.

[0014] (4) According to a fourth aspect of the present invention, in the fishing lure according to any one of the first to third aspects, the engaging portion may be a pin member that engages the mounting member and the engaged portion.

[0015] In this case, since at least one of the pin member and the engaged portion of the main body engaged with the pin member disassembles in water (in the sea), the assembly component having the pin member can be separated from the main body in water (in the sea).

[0016] (5) A fifth aspect of the present invention may be the fishing lure according to any one of aspects 1 to 4, wherein the main body has a hollow portion, and the engaged portion may be separated from the hollow portion.

[0017] In this case, the engaged portion is separated from the hollow portion of the main body. Therefore, even if at least one of the engaging portion and the engaged portion disassembles in water, the hollow portion of the main body does not form a hole communicating with the outside. Therefore, even if at least one of the engaging portion and the engaged portion disassembles, when the assembly component is separated from the main body as at least one of the engaging portion and the engaged portion disassembles, the main body can easily float due to the hollow portion, and the main body can be effectively released from the bottom state.

[0018] (6) A sixth aspect of the present invention may be the fishing lure according to any one of aspects 1 to 5, wherein the main body has a buoyancy greater than its weight.

[0019] In this case, after the engagement state with the attachment member is released, the main body can float due to buoyancy and can be recovered by floating.

[0020] (7) A seventh aspect of the present invention may be the fishing lure according to any one of aspects 1 to 6, wherein the material degradable in water is a marine biodegradable resin.

[0021] In this case, even if the bait is left in the sea unintentionally by the fisherman, such as by a card bottom, at least one of the engaging portion of the attachment member and the engaged portion of the lure body can be biodegraded to release the engagement.

[0022] Furthermore, since at least one of the engaging portion and the engaged portion is made of a marine biodegradable resin, even if the area of ​​contact between the engaging portion or the engaged portion and the seawater is small, the seawater will penetrate the entirety of at least one of the engaging portion and the engaged portion due to capillary action, thereby efficiently causing the marine biodegradable resin in at least one of the engaging portion and the engaged portion to biodegrade.

[0023] Effects of the Invention

[0024] According to the fishing lure of the present invention, the strength of the engaging portion between the attachment member and the main body can be ensured, and the main body of the fishing lure that is stuck in the bottom can be released from the stuck state. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 It is a perspective view showing a fishing lure according to an embodiment of the present invention.

[0026] Figure 2 yes Figure 1 Side view of the bait shown.

[0027] Figure 3 This is a perspective view of a fishing lure according to a second embodiment. DETAILED DESCRIPTION

[0028] Hereinafter, embodiments of the fishing lure of the present invention will be described with reference to the accompanying drawings. In the drawings, the scale of each component may be appropriately changed as needed to make each component a size that can be visually recognized.

[0029] (First embodiment)

[0030] Figure 1 It is a perspective view of the fishing lure 1 according to the first embodiment. Figure 2 yes Figure 1 A side view of the fishing lure 1 is shown.

[0031] like Figure 1 and Figure 2 As shown, the bait 1 of the embodiment is used for fishing, and is a general bait imitating the shape of a shrimp, that is, a so-called lure, formed of a material such as ABS resin, as an example.

[0032] Here, in the fishing lure 1, the direction connecting the head 11 and the tail 13 in a straight line is defined as the front-back direction X1, the head 11 side is defined as the front or front side, and the tail 13 side is defined as the rear or rear side. Furthermore, the following description will be made with the lateral direction perpendicular to the front-back direction X1 defined as the left-right direction X2 when viewed from above.

[0033] The fishing lure 1 includes a pair of bifurcated main bodies 10, an umbrella hook 20 (mounting component, hook) having a shaft 21 (engaging portion) that engages with the rear end 10b of the main body 10, an eyelet 30 (mounting component) having an engaging ring 31 (engaging portion) that engages with the front end 10a of the main body 10, and a sinker 40 (mounting component) attached to the lower portion of the main body. The sinker 40 is secured between the bifurcated main bodies 10 by a fixing pin 41 (engaging portion) made of a material that decomposes in water, such as magnesium.

[0034] The main body 10 is formed into a streamlined shape, and the peripheral edges of a pair of half-divided main bodies are joined together by bonding or welding. The main body 10 is integrally provided with a head 11, a body 12, and a tail 13. Figure 1 and Figure 2 In FIG. 1 , the left side of the paper is the front end portion 10 a on the head portion 11 side of the main body 10 , and the right side of the paper is the rear end portion 10 b on the tail portion 13 side of the main body 10 .

[0035] The main body 10 has the largest cross section at the center 10e in the front-back direction X1. That is, the main body 10 becomes thicker from the front end 10a to the center 10e and becomes thinner from the center 10e to the rear end 10b, forming a smooth curve as a whole.

[0036] like Figure 2As shown, the body 12 of the main body 10 is formed with a hollow portion 100. The head 11 and tail 13 are solid. The main body 10 has engaged portions 14, 15, and 16 that respectively cover the shaft 21 of the umbrella hook 20, the engaging ring 31 of the eyelet 30, and the fixing pin 41 of the sinker 40.

[0037] In the main body 10 , at least the engaging portion (the shaft portion 21 , the engaging ring 31 , the fixing pin 41 ) and any one of the engaged portions 14 , 15 , and 16 thereof are formed of a material having a property of being decomposable in water.

[0038] Examples of materials that decompose in water include marine biodegradable resins made from biomass plastics, such as cellulose acetate or PHA (polyhydroxyalkanoate). Among PHAs, P3HB (poly[(R)-3-hydroxybutyrate]) and its copolymers, namely P3HB4HB (poly[(R)-3-hydroxybutyrate-co-4-hydroxybutyrate]), P3HBV (poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyvalerate]), and P3HBH (poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate]), are particularly well-characterized as materials with excellent biodegradability (marine biodegradability) in seawater.

[0039] In addition, the main body 10 has a buoyancy greater than its weight and can float due to the buoyancy.

[0040] The inner surface 10c of the main body 10, which faces the hollow portion 100, is provided with a reinforcement rib 101 that protrudes toward the hollow portion 100. The reinforcement rib 101 extends vertically, with the rib surface intersecting the front-back direction X1. The reinforcement rib 101 reinforces the main body 10, which is formed of a biodegradable resin material. This enhances the strength of the main body 10, making it more resistant to external pressure.

[0041] The shaft portion 21 of the umbrella hook 20 protrudes from the rear end portion 10b of the main body 10. The shaft portion 21 is a pin member that engages with the main body 10 with its axial direction oriented in the front-to-rear direction X1 of the main body 10, with a portion (fixed end portion 21a) inserted. The umbrella hook 20 is mounted on the shaft portion 21 protruding from the rear end portion 10b of the main body 10. The umbrella hook 20 includes the shaft portion 21 and is disposed outside the main body 10. The rear end portion 10b of the main body 10 has a first engaging hole 14a into which the fixed end portion 21a of the shaft portion 21 engages.

[0042] The first engaging hole 14a is included in a portion of the first engaged portion 14. The first engaged portion 14 is provided in the solid tail portion 13 of the main body 10, and is provided at a position separated from the hollow portion 100. Therefore, even if either the shaft portion 21 or the first engaged portion 14 disintegrates in water, the hollow portion 100 as a whole can remain sealed.

[0043] In addition, in the present embodiment, a gap communicating with the surface of the main body 10 may be partially provided between the shaft portion 21 and the first engaged portion 14 .

[0044] The eyelet 30 includes a snap ring 31, a line connecting ring 32, and a shaft body 33. The snap ring 31 is provided at one end of the shaft body 33, and the line connecting ring 32 is provided at the other end. The snap ring 31 and the shaft body 33 are inserted into and engaged with a second snap hole 15a, which opens at the front end 10a of the main body 10. The second snap hole 15a is a recessed portion having a substantially identical shape to the snap ring 31 and the shaft body 33 that are engaged with the main body 10. The line connecting ring 32 protrudes forward from the front end 10a of the main body 10 and is connected to a fishing line 34.

[0045] The second engaging hole 15a is included in a portion of the second engaged portion 15. The second engaged portion 15 is provided in the solid head portion 11 of the main body 10, and is provided at a position separated from the hollow portion 100. Therefore, even if either the engaging portion 31 or the second engaged portion 15 disintegrates in water, the hollow portion 100 as a whole can remain sealed.

[0046] In addition, in the present embodiment, a gap communicating with the surface of the main body 10 may be partially provided between the wire connecting ring 32 and the second engaged portion 15 .

[0047] The sinker 40 is sandwiched between the two divided parts of the main body 10 at the lower part of the head side of the body 12. The sinker 40 has a through hole 40a and is fixed to the main body 10 by engaging with a fixing pin 41 in the through hole 40a. The fixing pin 41 is inserted through the engagement hole 16a, which extends through each of the two divided parts of the main body 10.

[0048] The engaging hole 16a is included in a portion of the third engaged portion 16. The third engaged portion 16 is the portion of the body 12 of the main body 10 that holds the sinker 40 and is located at a position spaced apart from the hollow portion 100. Therefore, even if the fixing pin 41 or the third engaged portion 16 disintegrates in water, the hollow portion 100 as a whole can remain sealed.

[0049] In addition, in the present embodiment, a gap communicating with the surface of the main body 10 may be partially provided between the fixing pin 41 and the third engaged portion 16 .

[0050] Then, based on Figure 1 and Figure 2 The operation of the fishing lure 1 thus constructed will be described in detail.

[0051] The fishing lure 1 of this embodiment includes mounting components (hook 20, eyelet 30, and sinker 40) having engaging portions (shaft 21, engaging ring 31, and fixing pin 41) that engage with the main body 10, and engaged portions 14, 15, and 16 that cover the engaging portions (shaft 21, engaging ring 31, and fixing pin 41) in the main body 10. At least one of the engaging portions (shaft 21, engaging ring 31, and fixing pin 41) and the engaged portions 14, 15, and 16 is formed of a material that decomposes in water.

[0052] According to the fishing lure 1 of this embodiment, at least one of the shaft 21 of the umbrella hook 20, the engaging ring 31 of the eye 30, the fixing pin 41 of the sinker 40, and the engaged portions 14, 15, and 16 of the main body 10, which are attached to the main body 10 of the fishing lure 1 and engage therewith, is formed of a water-degradable material such as a biodegradable resin. Therefore, when the fishing lure 1 is continuously immersed in water (in the sea), the engaged portions 14, 15, and 16, which are made of a water-degradable material, decompose. For example, if the water-degradable material is a biodegradable resin, the engaged portions 14, 15, and 16 biodegrade. Therefore, the engagement between the shaft portion 21, the engaging ring 31, and the fixing pin 41 and the engaged portions 14, 15, and 16 is released. Even if, for example, the lure 1 becomes stuck, the body 10, the umbrella hook 20, the eyelet 30, and the sinker 40 can be separated by disassembling at least one of the engaging portions (the shaft portion 21, the engaging ring 31, and the fixing pin 41) and the engaged portions 14, 15, and 16. This allows at least the body 10 of the lure 1 to be released from the stuck state. Furthermore, if the shaft portion 21 is formed of a material that decomposes in water, there may be cases where only the umbrella hook 20 remains in the water.

[0053] Furthermore, this embodiment utilizes a structure that utilizes the decomposition of components that decompose in water to separate the main body 10 from the attached components (hook 20, eyelet 30, and sinker 40). This differs from conventional structures that set the breakage strength of the components below the strength of the fishing line, breaking the components when they become stuck and recovering the main body. Therefore, the lure 1 of this embodiment maintains sufficient strength at the points where the hook 20, eyelet 30, and sinker 40 engage the main body 10, enabling the reeling in of large fish without damaging the components, similar to conventional fishing lures.

[0054] In addition, in this embodiment, gaps communicating with the surface of the main body 10 are provided between the engaging portions (the shaft portion 21 , the engaging ring 31 , and the fixing pin 41 ) and the corresponding engaged portions 14 , 15 , and 16 .

[0055] With this configuration, when the fishing lure 1 remains in the water (in the sea), water seeps from the surface of the body 10 into the gaps between the shaft 21, the engaging ring 31, and the fixing pin 41, and the corresponding engaged portions 14, 15, and 16, further accelerating the disassembly of the engaged portions 14, 15, and 16. Consequently, the gaps between the engaged portion 14 and the shaft 21, the gap between the engaged portion 15 and the engaging ring 31, and the gap between the engaged portion 16 and the fixing pin 41 increase, causing looseness, making it easier to release the engagement between the shaft 21, the engaging ring 31, and the fixing pin 41 and the engaged portions 14, 15, and 16.

[0056] Furthermore, in this embodiment, the second engaged portion 15 of the main body 10, which is engaged with the engaging ring 31 of the eyelet 30, disassembles in water (in the sea), and can therefore be separated from the main body 10 in water (in the sea). Thus, even if a weight or the like provided on the line side becomes stuck, the lure 1 can be released from the stuck state.

[0057] In addition, in the present embodiment, the shaft portion 21 of the umbrella hook 20 is a pin member that engages the umbrella hook 20 with the first engaged portion 14 .

[0058] Thus, since at least one of the shaft portion 21 and the first engaged portion 14 of the main body 10 is disassembled in water (in the sea), the umbrella hook 20 can be separated from the main body 10 in water (in the sea).

[0059] In addition, in this embodiment, the main body 10 has the hollow portion 100 . The engaged portions 14 , 15 , and 16 are separated from the hollow portion 100 .

[0060] With this configuration, even if at least one of the shaft portion 21, engagement ring 31, fixing pin 41, and engaged portions 14, 15, and 16 that constitute the engaging portion disassemble underwater, the hollow portion 100 of the main body 10 does not form a hole communicating with the outside. Therefore, even if disassembly proceeds, when the umbrella hook 20, eyelet 30, and sinker 40 detach from the main body 10 as at least one of the engaging portion and the engaged portion disassembles, the main body 10 easily floats due to the presence of the hollow portion 100, effectively releasing the main body 10 from the stuck state.

[0061] In addition, in this embodiment, the buoyancy of the main body 10 is greater than its weight. Therefore, after the engagement with the umbrella hook 20, the eyelet 30 and the sinker 40 is released, the main body 10 can float and be recovered by the buoyancy.

[0062] Furthermore, in this embodiment, the material that decomposes in water is a marine biodegradable resin. Therefore, even if the lure 1 is left in the sea unintentionally by the angler, such as by a hook, at least one of the engaging portions (shaft 21, engaging ring 31, and fixing pin 41) of the assembly components (hook 20, eyelet 30, sinker 40) and the engaged portions 14, 15, and 16 of the main body 10 of the lure 1 biodegrades, releasing the engagement with the hook 20, eyelet 30, and sinker 40.

[0063] Furthermore, since the engaging portion (the shaft portion 21, the engaging ring 31, and the fixing pin 41) or the engaged portions 14, 15, and 16 are made of a marine biodegradable resin, even if the area of ​​contact between each portion and seawater is small, seawater will penetrate into the entirety of at least one of the engaging portion (the shaft portion 21, the engaging ring 31, and the fixing pin 41) and the engaged portions 14, 15, and 16 due to capillary action, thereby efficiently causing the engaging portion (the shaft portion 21, the engaging ring 31, and the fixing pin 41) and at least one of the engaged portions 14, 15, and 16 to undergo biodegradation.

[0064] In the fishing lure 1 of this embodiment configured as described above, the hook 20 , eyelet 30 , and sinker 40 as the assembly components can ensure the strength of the engagement portion with the body 10 , while the hook 20 , eyelet 30 , and sinker 40 can be released from the stuck state.

[0065] (Second embodiment)

[0066] Figure 3 It is a perspective view of a fishing lure 1A according to a second embodiment.

[0067] like Figure 3 As shown, the lure 1A of the second embodiment has a body 10A with an eye 30 similar to that of the first embodiment provided at the front end 10a of the head 11, a tail eye 50 provided at the rear end 10b of the tail 13, and a shank eye 60 provided on the lower surface 12a of the shank 12. The eye 30 has the same structure as that of the first embodiment, and therefore a detailed description thereof will be omitted.

[0068] The main body 10A includes engaged portions 17 and 18 that respectively cover a portion of the tail eye 50 (a first engaging member 51, described below) and a portion of the body eye 60 (a second engaging member 61, described below). At least one of the first engaging member 51, the second engaging member 61, and the engaged portions 17 and 18 of the main body 10A is formed from a biodegradable resin material that decomposes in water. The biodegradable resin can be the same material as that exemplified in the first embodiment.

[0069] The tail eye 50 includes a first engaging member 51 (engaging portion) and a first hook connecting ring 52. The first engaging member 51 is inserted into and engaged with a fourth engaging hole 17a, which opens at the rear end 10b of the main body 10A. The fourth engaging hole 17a is a recessed portion having a substantially identical shape to the first engaging member 51 engaged with the main body 10A. The first hook connecting ring 52 protrudes rearward from the rear end 10b of the main body 10A and is connected to a fishing hook (fish hook) 53.

[0070] The fourth engaging hole 17a is included in a portion of the fourth engaged portion 17. The fourth engaged portion 17 is provided in the solid tail portion 13 of the main body 10A, and is provided at a position separated from the hollow portion 100. Therefore, even if at least one of the first engaging member 51 and the fourth engaged portion 17 disintegrates in water, the hollow portion 100 as a whole can remain sealed.

[0071] In addition, in the present embodiment, a gap communicating with the surface of the main body 10A may be partially provided between the first engaging member 51 and the fourth engaged portion 17 .

[0072] The shank eye 60 includes a second engaging member 61 (engaging portion) and a second hook connecting ring 62. The second engaging member 61 is inserted into and engaged with a fifth engaging hole 18a, which opens on the lower surface 12a of the shank 12 of the main body 10A. The fifth engaging hole 18a is a recessed portion having a substantially identical shape to the second engaging member 61 engaged with the main body 10A. The second hook connecting ring 62 protrudes downward from the lower surface 12a of the main body 10A and is connected to a hook (fish hook) 63.

[0073] The fifth engaging hole 18a is included in a portion of the fifth engaged portion 18. The fifth engaged portion 18 is provided on the lower surface 12a side of the body portion 12 in the main body 10A and is provided at a position spaced apart from the hollow portion 100. Therefore, even if at least one of the second engaging member 61 and the fifth engaged portion 18 disintegrates in water, the hollow portion 100 as a whole can remain sealed.

[0074] In addition, in this embodiment, a gap communicating with the surface of the main body 10A may be partially provided between the second engaging member 61 and the fifth engaged portion 18. Furthermore, the head portion 11, the body portion 12, and the tail portion 13 of the main body 10A may be separately provided so that the respective portions can freely swing in the left-right direction X2.

[0075] While the above descriptions describe embodiments of the fishing lure of the present invention, these embodiments are provided for illustrative purposes only and are not intended to limit the scope of the invention. The embodiments may be implemented in various other forms, and various omissions, substitutions, and modifications may be made without departing from the gist of the invention. The embodiments and their modifications include, for example, those readily apparent to those skilled in the art, those that are substantially equivalent, and those within the scope of equivalents.

[0076] For example, in the above embodiment, the assembly components include the parachute hook 20 (fish hook), the eye 30, the hook eyes 50 and 60, and the sinker 40, but are not limited to these. In short, any assembly component may be provided separately from the main body of the lure and assembled from the outside of the main body, and there are no particular restrictions on its function, type, or size.

[0077] Furthermore, while the engaging shape of the engaging portion and the engaged portion of the main body is, for example, a pin-shaped member is employed as the shaft portion 21 of the umbrella hook 20 in the first embodiment, this engaging shape is not limited thereto. Specifically, the pin-shaped engaging portion has the advantage of being easily detached from the main body when at least one of the engaging portion and the engaged portion is disassembled. However, since the assembly component and the main body are separated as soon as at least one of the engaging portion and the engaged portion is disassembled, other shapes other than a pin-shaped member, such as a thread eye or hook eye, may also be employed.

[0078] Furthermore, in this embodiment, the engaged portion is separated from the hollow portion of the main body, but the present invention is not limited thereto. That is, the engaged portion may be connected to the hollow portion of the main body.

[0079] Furthermore, the secondary blade structure such as the shape and number of divisions of the lure and the shape, number, and attachment position of the hooks attached to the lure can be changed as appropriate.

[0080] Various biomass plastics are exemplified as marine biodegradable resins, but the materials themselves do not necessarily have to be biologically derived. Examples include PBSA, PCL, PA4, and biodegradable materials with additives imparting marine biodegradability.

[0081] Furthermore, the material that can be decomposed in water is not limited to marine biodegradable resins, and may be, for example, a metal material with low environmental impact such as magnesium.
