Description

[Technical field]

[0001] The present invention relates to a lure for use in lure fishing and a method for manufacturing a lure. [Background technology]

[0002] Fishing using lures is called lure fishing, and there are many enthusiasts of this sport. There are many different types of lures, and they can be freely selected depending on the target fish, water temperature, and the user's preferences.

[0003] Among various lures, top water lures, which float on the water surface, have been used for a long time in lure fishing and are said to be highly interesting lures. Top water lures not only encourage fish to prey on them as artificial bait, but also intimidate fish and arouse their curiosity, which can induce them to bite the lure. As mentioned above, top water lures float on the water surface, so they can move on the water surface. Therefore, you can see fish jumping on the lure on the water surface and biting it, making them one of the most popular lures. For example, it is possible to lure large fish such as tuna near the water surface with a top water lure and catch them.

[0004] A lure, which is an artificial bait, is required to move similarly to a real fish. For example, when fishing for a fish that preys on fish that move on the water surface, the lure is required to move similarly to the preyed fish, and buoyancy is required to move the lure on the water surface. In addition, the center of gravity is also important for controlling the movement and posture of the lure. A top water lure needs to have a specific gravity lighter than water so that it floats on the water surface, and materials such as resin and wood are used. Resin lures are the most widely used because they are easy to mass-produce and have a high degree of freedom in shape. On the other hand, wooden lures have a low specific gravity and move similarly to a real fish. Therefore, wooden lures are excellent in terms of fishing results, and wooden top water lures have many fans. For example, Patent Document 1 can be cited as a conventional resin lure. For example, Patent Document 2 can be cited as a conventional wooden lure. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4346186 [Patent Document 2] JP 2004-222630 A Summary of the Invention [Problem to be solved by the invention]

[0006] As mentioned above, resin lures are widely used, but because they have a higher specific gravity than wooden lures, it is difficult to make them move like real fish. On the other hand, wooden lures are good for catching fish because they are easier to make move like real fish, but the strength of the wood itself is often lower than that of resin materials, and with continued use, water gradually seeps into the interior from the painted surface, making the wooden parts prone to deterioration. Therefore, wooden lures are less durable than regular resin lures. As such, conventional resin lures and wooden lures each have their own advantages and disadvantages, so there is a need to develop a lure that combines the good points of both.

[0007] The present invention has been made in view of the above background, and aims to provide a lure that is excellent in terms of fishing results because it can move in a manner similar to that of a real fish, and that also has excellent durability, and a manufacturing method thereof. [Means for solving the problem]

[0008] The carbon lure of the present invention is a fishing lure that imitates a roughly spindle-shaped fish, and comprises a main body that forms the outer shell of the lure, a connecting support member and a sinker provided inside the main body, a resin member filled inside the main body, and a plurality of eyes protruding to the outside of the main body, the connecting support member being a member that connects the plurality of eyes and supports the sinker, and the main body being a molded body of woven carbon fiber fabric impregnated with a thermosetting resin.

[0009] The main body consists of two divided bodies divided along the longitudinal direction of the approximately spindle shape, and the two divided bodies have joints that fit into each other, one of the joints is a female joint without a step, and the other joint is a male joint having an outer periphery located on the outside of the joint and a step located on the inside, the outer periphery of the step part fits into the inner periphery of the female joint, and the outer periphery surface of the outer periphery of the male joint and the outer periphery surface of the female joint are joined without a step.

[0010] The fiber direction of the carbon fiber woven fabric is not perpendicular to the longitudinal direction of the approximately spindle shape.

[0011] The method for manufacturing a carbon lure of the present invention is a method for manufacturing a fishing lure that imitates a roughly spindle-shaped fish, and includes a step of manufacturing two split bodies that are split along the longitudinal direction of the roughly spindle shape and that constitute the main body that becomes the outer shell of the lure, and a step of joining the two resulting split bodies, wherein the step of manufacturing the split bodies includes a placement step of placing a prepreg made of woven carbon fiber fabric impregnated with a thermosetting resin along a concave mold having a groove in the shape of the lure outer shell, a loading step of loading a resin nest from above the prepreg, and a molding step of heating and baking the prepreg and resin nest while sandwiched between a pressing plate that presses them against the concave mold to harden the prepreg.

[0012] the two divided bodies have joints that fit together, one of the joints being a female joint without a step, and the other joint being a male joint having an outer periphery disposed outside the first joint and a step disposed inside the first joint; In the molding process for manufacturing the divided body having the male joint, a step-forming member having a thin groove similar in shape to the edge of the concave groove and smaller than the inner dimension of the edge of the concave groove is placed between the concave mold and the pressing plate, and the step-forming member is placed so as to overlap the concave groove of the concave mold, and the prepreg is placed up to the inner diameter of the thin groove and the prepreg is hardened to form the step along the inner diameter of the thin groove. Effect of the Invention

[0013] The carbon lure of the present invention is a fishing lure that imitates a spindle-shaped fish, and includes a main body that constitutes an outer shell, a connecting support member and a weight provided inside the main body, a resin member filled inside the main body, and a number of eyes protruding from the outside of the main body, the connecting support member is a member that connects the multiple eyes and supports the weight, and the main body is a molded body of carbon fiber woven fabric impregnated with a thermosetting resin, so in addition to the lure's low specific gravity, the center of gravity can be set by the weight, and the outer shell material and the resin filled inside give it high strength. As a result, the carbon lure of the present invention can move in a manner similar to that of a real fish, so it is excellent in terms of fishing results and durability.

[0014] In addition, the main body is made up of two split bodies split along the longitudinal direction of the approximately spindle shape, and at the joints (male and female) of the two split bodies, the outer periphery of the stepped part of the male joint fits into the inner periphery of the female joint, so that the split bodies, which are molded bodies of woven carbon fiber fabric impregnated with thermosetting resin, can be firmly joined together, and the strength of the main body can be further increased. Also, since the outer peripheral surface of the outer peripheral part of the male joint and the outer peripheral surface of the female joint are joined without any steps, there are no irregularities at the joints between the split bodies, so that the appearance resembles a real fish, and an improvement in the fish attracting effect can be expected.

[0015] In addition, since the fiber direction of the carbon fiber woven fabric is not perpendicular to the longitudinal direction of the approximately spindle shape, the weave of the carbon fiber woven fabric looks like fish scales, which is more likely to attract nearby fish and lead to better fishing results.

[0016] The method for producing a carbon lure of the present invention includes a step of producing two split bodies divided along the longitudinal direction of a substantially spindle shape that constitutes the main body that becomes the outer shell of the lure, and a step of joining the two split bodies obtained, and the step of producing the split bodies includes a step of arranging a prepreg made of a carbon fiber woven fabric impregnated with a thermosetting resin along a concave mold having a concave groove in the shape of the lure outer shell, a step of loading a resin insert from above the prepreg, and a molding step of heating and baking the prepreg while sandwiching the prepreg and the resin insert between a pressing plate that presses against the concave mold to harden the prepreg, so that the prepreg can be pressed by the thermal expansion of the resin insert, and a lure body that is a carbon fiber woven fabric reinforced resin molded body can be produced without an autoclave or vacuum bag. This allows a lure with a low specific gravity, no structural defects, and a high-strength outer shell to be produced at low cost.

[0017] In addition, as a molding process for manufacturing a split body having a male joint out of the joints (male and female) of the two split bodies, a step-forming member having a thin groove similar in shape to the edge of the concave groove and smaller than the inner dimensions of the edge of the concave groove is placed between the concave mold and the pressing plate, and is overlapped on the concave groove of the concave groove.The prepreg is placed up to the inner diameter of the thin groove and then hardened to form a step along the inner diameter of the thin groove.This makes it possible to easily form a fitting shape during molding that can improve the joint strength between the split bodies in a carbon fiber woven fabric reinforced resin molded body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] An embodiment of the lure of the present invention will be described with reference to Fig. 1. Fig. 1 shows a perspective view of the inside of the lure with a partly transparent view. As shown in Fig. 1, the lure 1 is a fishing lure that imitates a spindle-shaped fish. The size of the lure 1 is, for example, about 20 cm in length in the longitudinal direction and about 3 cm in width. The lure 1 includes a main body 2 that constitutes an outer shell, a connecting support member 4 and a weight 6 provided inside the main body 2, a resin member 3 filled inside the main body 2, and a plurality of eyes 5 that protrude to the outside of the main body 2.

[0020] The main body 2 is a prepreg molded body made of carbon fiber woven fabric impregnated with a thermosetting resin. In general resin lures, ribs are often provided inside the main body to reduce the specific gravity and increase strength at the same time, but forming ribs with prepreg requires a lot of time during the molding process. When the main body is a prepreg molded body, the strength of the main body can be easily ensured even without ribs due to its high rigidity, so the inside of the main body 2 can be made hollow. The main body 2 has two through holes 12 in the abdomen. The lure 1 is a solid body with the resin member 3 filled from the through hole 12 inside the main body 2. The main body 2 may be provided with eyes, fins, a lip, a scale pattern, etc. as appropriate.

[0021] The inside of the main body 2 is filled with urethane resin as the resin member 3. Since the inside of the main body is filled with the resin member, the strength of the lure is high and it has excellent durability. In addition, it is possible to prevent water from entering the inside of the main body 2. In addition to general urethane resin, for example, foamed polyurethane or silicone resin may be selected as the resin member. From the viewpoint of imparting the necessary buoyancy to the top water lure, it is preferable that the resin member has a low specific gravity. In addition, the resin member 3 may not fill the entire space inside the main body 2, but may fill only a predetermined amount. This can further reduce the specific gravity of the lure and further improve the buoyancy. In addition, the resin member 3 may be placed (filled) inside the main body 2 when the main body 2 is joined after being molded in advance. In addition, in this case, the resin member 3 may be fixed to the connecting support member 4.

[0022] The connecting support member 4 is a member that connects the multiple eyes 5 and supports the sinker 6. Specifically, the connecting support member 4 connects the eyes 5a, 5b, and 5c that are arranged at the head 2a, the abdomen 2b, and the tail 2c of the main body 2. A fishing line is attached to the eye 5a, and a fishhook is attached to the eyes 5b and 5c. The material of the connecting support member 4 is not particularly limited, and it can be made of resin or metal. Since each eye is mainly made of metal such as stainless steel, it is preferable that the connecting support member 4 is made of metal and is an integral member with each eye.

[0023] The connecting support member 4 is provided with a weight 6 on the tail 2c side for adjusting the center of gravity of the lure 1. The weight 6 is made of metal such as stainless steel, tungsten, or lead. In a typical resin lure, it is easy to fix the weight at any position by providing a shape such as a rib inside the main body. On the other hand, in the lure of the present invention, the inside of the main body 2 is a hollow structure, and as described above, it is not easy to provide a shape such as a rib. Based on this, in the lure of the present invention, the connecting support member 4 is provided in the hollow structure of the main body 2, and the weight 6 can be arranged at any position on the rod-shaped support part 4a. As a result, it is possible to arrange the weight in consideration of the posture of the lure in water, even though the main body is a hollow structure of a carbon fiber woven fabric reinforced resin molded body.

[0024] Figure 2 shows an exploded perspective view of the lure shown in Figure 1. The main body 2 is made up of two segments 7 separated along the longitudinal direction of the approximately spindle shape at a cross section passing through the back and abdomen.

[0025] Figure 3 shows the two segments before and after they are fitted together and joined. Figure 3(a) is a circumferential cross-sectional view of the abdomen before the two segments are joined, and Figure 3(b) is a circumferential cross-sectional view of the abdomen after the two segments are joined. Split segments 7a and 7b have joints 13a and 13b, respectively, which fit together.

[0026] The joint of the divided body 7a is a female joint 13a without a step. On the other hand, the joint of the divided body 7b is a male joint 13b having an outer periphery 13c arranged on the outside of this joint and a step 13d arranged on the inside. The outer periphery 13c of the male joint 13b has an abutting surface that abuts against the end face of the female joint 13a. The outer periphery of the male outer periphery 13c and the outer periphery of the female joint 13a are joined without a step. In the male joint 13b, the step width between the outer periphery of the outer periphery 13c and the outer periphery of the step 13d is approximately the same as or slightly larger than the thickness of the female joint 13a. The outer periphery of the step 13d fits into the inner periphery of the female joint 13a, and the joints are firmly fixed to each other by adhesive.

[0027] The method of joining the two divided bodies is not limited to the fitting method described above. For example, the end faces of each joint may be fixed together only with adhesive. Since the main body is a carbon fiber woven fabric reinforced resin molded body and its end faces are cut parts of the woven fabric, it may not be easy to bond them depending on the shape of the cut surface. In contrast, by using a structure in which the joints are fitted together, it is not necessary to consider the cut shape of the end faces of the divided bodies, and the structure is stable and the bonding area can be made large, so that the divided bodies can be firmly and reliably joined together.

[0028] The divided bodies constituting the main body are formed, for example, by heating and baking a prepreg in which a twill woven 3K carbon fiber fabric is impregnated with a thermosetting resin. Here, the "3K carbon fiber fabric" is a woven fabric using fiber bundles in which monofilaments with a fiber diameter of about several μm are arranged in a bundle of about 3000 pieces. Therefore, the main body has a high-strength outer shell and is excellent in durability. In addition, the fiber direction of the carbon fiber fabric is not perpendicular to the longitudinal direction of the approximately spindle shape of the lure, and for example, the fiber direction is about 45° relative to the longitudinal direction. As a result, the weave of the woven fabric looks like the scales of the fish that will be used as bait, so that a fish-attracting effect can be expected. In addition to the divided bodies molded using a prepreg in which a thermosetting resin has been previously impregnated into a carbon fiber fabric, the divided bodies may be molded by sequentially impregnating the carbon fiber fabric with a thermosetting resin and heat curing it.

[0029] The weaving pattern of the carbon fiber woven fabric constituting the prepreg is not limited to twill weave, but may be plain weave. Also, it is not limited to 3K, but may be 1K, 5K, etc. The carbon fiber material may be either polyacrylonitrile (PAN)-based or pitch-based. From the viewpoint of processability and strength, the carbon fiber woven fabric is preferably a 3K twill PAN-based carbon fiber woven fabric. Also, the thermosetting resin may be selected from, for example, epoxy resin, phenol resin, unsaturated polyester resin, etc. From the viewpoint of curability and mechanical properties of the cured product, the resin of the prepreg is preferably an epoxy resin.

[0030] The carbon lure of the present invention has a main body, which is the outer shell, made of a carbon fiber woven fabric reinforced resin molded body, and a resin member and a connecting support member (capable of supporting a weight) are provided inside the main body, so the specific gravity of the lure is small (less than 1), the center of gravity can be set on the connecting support member by using the weight, and the filled resin member can suppress the weight from shifting position. As a result, the carbon lure of the present invention can stably achieve movements similar to those of real fish, and is excellent in fishing results.

[0031] An embodiment of the manufacturing process of the lure of the present invention will be described below with reference to Figures 4 and 5. Figure 4 shows the positional relationship between the prepreg and the molding die when molding the prepreg into the divided bodies in the manufacturing process of the divided bodies. Figure 5 shows a cross-sectional view of the prepreg, a resin insert, and a molding die in the molding process in which the divided bodies are molded while pressing the prepreg with the insert.

[0032] The manufacturing process for the lure of the present invention includes a step of manufacturing two split bodies separated along the longitudinal direction of a generally spindle shape that constitutes the main body that becomes the outer shell of the lure (split body manufacturing step), and a step of joining the two resulting split bodies (joining step). Below, each step included in the split body manufacturing step will be explained in (1) to (3), and the joining step and other steps will be explained in (4) to (6).

[0033] (1) Placement process In the arrangement step, three prepregs (e.g., epoxy-impregnated carbon fiber woven fabric: 3K, thickness after curing: 0.2 mm) in which carbon fiber woven fabric is impregnated with a thermosetting resin are arranged along a concave mold 8, which is a molding die having a concave groove 81 that is the shape of the outer shell of the lure. Of the three prepregs to be layered, the prepreg to be arranged in the outermost shell is arranged so that the fiber direction of the carbon fiber woven fabric is at an angle of, for example, about 45° with respect to the longitudinal direction of the approximately spindle shape of the completed lure. In addition, when layering, the prepregs are arranged so that the fiber directions are not the same. Before arranging the prepregs, a release agent or the like is sprayed inside the concave groove 81 to form a release coating. In order to form a through hole for filling the resin member inside the main body, after arranging the prepregs, a semi-cylindrical jig is fitted into two places that correspond to the through holes of the abdomen after molding.

[0034] (2) Loading process In the loading step, a solid silicone resin insert 11 previously molded using a recessed mold 8 is loaded, and the prepreg is pressed against the inner surface of the recessed mold 8. The size of the insert 11 is such that the prepreg and the pressing plate 9 are in close contact with each other inside the recessed mold 8 before heating and firing. Any excess prepreg that protrudes from the gap between the recessed mold 8 and the silicone resin insert 11 during loading is removed with a cutter, and the ends of the prepreg are aligned on a flat surface (see FIG. 5(a)). Note that, before loading the resin insert, a release agent may be sprayed onto the prepreg arranged along the recessed mold, to form a release coating on the inner surface of the prepreg.

[0035] Due to its linear thermal expansion coefficient, the silicone resin insert expands appropriately under the heating and baking conditions of the epoxy resin-impregnated prepreg, and can sufficiently press the prepreg. This makes it unnecessary to evacuate (autoclave or vacuum bag) during the molding process. Furthermore, since the silicone resin insert has low surface energy, it is easy to release from the prepreg after the molding process even if no release agent is used. Note that the insert is not limited to silicone resin, and any resin that is heat resistant above the heating and baking temperature, soft, and thermally expandable can be appropriately selected.

[0036] (3) Molding process In the molding process, the prepreg and silicone resin insert 11 are sandwiched between a pressing plate 9 that presses against the concave mold 8. The pressing plate 9 and the concave mold 8 are fixed by inserting bolts (not shown) into multiple fixing holes provided at the four corners and the center of the long sides. While being pressed, the prepreg is thermally cured by heating and baking at normal pressure, for example, at about 120°C to 150°C for about 3 hours to 5 hours to form the divided bodies (see FIG. 5(a)). During heating and baking, the silicone resin insert 11 thermally expands and presses uniformly against the prepreg, so that an outer shell can be molded according to the design that matches the inner shape of the concave mold 8.

[0037] Here, the process for manufacturing a split body having a male joint will be described with reference to Figures 4(b) and 5(b). The process for manufacturing a split body having a male joint is partially different from the process for manufacturing a split body having a female joint (Figures 4(a) and 5(a)).

[0038] Between the mold 8 and the pressing plate 9, a step-forming member 10 is placed, which is provided so as to overlap the groove 81 of the mold 8, and has a thin groove 10b similar in shape to the edge of the groove 81 and smaller than the inner dimension of the edge of the groove 81. With the prepreg placed up to the inner diameter of the thin groove 10b, the prepreg is cured to form a step 13d along the inner diameter of the thin groove 10b. More specifically, in the placing step, a prepreg slightly larger in size than the groove 81 of the mold 8 is placed, and then in the loading step, the insert 11 is loaded. Thereafter, the step-forming member 10 is placed against the mold 8 so that the end of the prepreg protruding from the groove 81 is aligned with the inner diameter of the thin groove 10b. At this time, the excess prepreg protruding from the thin groove 10b of the step-forming member 10 is removed by a cutter. Finally, in the molding step, the prepreg and insert 11 are pressed against the recessed mold 8 by a pressing plate 9 disposed on the step-forming member 10, while being heated and baked to be molded.

[0039] As a result, a step portion 13d is formed on the inside of the joint of one of the divided bodies 7b. When the two divided bodies are joined with adhesive, the protruding width of the step portion 13d from the step surface (the thickness of the step portion forming member 10) becomes the main adhesive margin. This protruding width is set to a width that allows these divided bodies to be joined with sufficient strength. In addition, it is preferable to provide a gap of the adhesive layer between both divided bodies at the joint so that these divided bodies can be joined without a step on the outer periphery. By providing this gap, even if there is a distortion in the shape of the step portion of the joint of the divided bodies, the adhesive layer can absorb the distortion. From the viewpoint of providing this gap, it is preferable that the thickness T of the divided body 7a that fits into the divided body 7b has the following relationship with the inner dimension W1 of the outer edge of the recessed groove 81 and the inner dimension W2 of the outer edge of the thin groove 10b. T:(W1-W2) / 6 <T<(W1-W2) / 2 This provides the above-mentioned effect of providing a gap between the outer periphery of step portion 13d of the male joint and the inner periphery of female joint portion 13a, and as this gap does not become too large, the structure is more stable and can be fixed with an appropriate amount of adhesive.

[0040] Both divided bodies may be formed using a pressing plate and a concave mold without using a step forming member. In this case, two divided bodies each having a female joint are obtained. In the joining process, the end faces of the female joint are bonded together with an adhesive to obtain the main body. Bonding only the end faces results in a smaller bonding area than bonding the male and female joints. It is preferable that the end faces are smooth in order to achieve a higher adhesive strength in a small area.

[0041] (4)Joining process An adhesive such as an epoxy adhesive is applied to the joints of the two divided bodies, and the male and female joints are fitted together while the connecting support member that supports the weight is sandwiched between them to obtain the main body. Before the joining process, the weight is fixed in a desired position on the support part of the connecting support member.

[0042] (5) Polishing process The bonded body is immersed in water and waterproof sandpaper is used to remove burrs and adhesive from the surface of the body and to polish it.

[0043] (6) Filling process In the filling process, a resin material such as urethane resin is filled through a through hole provided in the abdomen of the body, and the lure is completed by hardening it (for example, the shape shown in Figure 1). In addition, eyes, fins, lips, scale patterns, etc. can be appropriately provided on the body as necessary.

[0044] In order to mold a complex three-dimensional shape with small curvature using laminated prepregs, generally, advanced processing technology and production equipment (such as an autoclave) are required. By using the manufacturing method of the present invention, a lure with a high-strength outer shell without structural defects can be manufactured inexpensively using simple equipment.

[0045] The carbon lure and the method for manufacturing the carbon lure of the present invention have been described above with reference to the drawings, but the configuration of the present invention is not limited thereto. [Industrial Applicability]

[0046] The carbon lure of the present invention and the carbon lure manufactured by the manufacturing method of the present invention are excellent in terms of fishing results because they can move in a manner similar to that of a real fish, and they are also highly durable, so they can be used as lures for a wide range of purposes.
