[0001] The present invention relates to fishing tackle.

Background Art

[0002] A fishing line guide for guiding a fishing line is known. The fishing line guide includes a frame attached to the outer peripheral surface of a fishing rod and a guide ring fixed to the frame through which the fishing line is actually inserted. The frame is integrally formed with a ring holding portion for holding the guide ring through which the fishing line is inserted and a fixing portion for attaching to the outer surface of the fishing rod. The frame was generally integrally formed by pressing a metal plate material such as stainless steel or titanium. When the product is made of a metal material, it is heavy and has poor performance such as flexibility. When a large number of fishing line guides having the above structure are mounted along the axial length direction, the whole becomes heavy, and a fishing rod that requires further weight reduction cannot exhibit the desired performance.

[0003] From such a viewpoint, a fishing line guide made of fiber reinforced plastic has been proposed. For example, "a method for manufacturing a fishing line guide having a ring holding portion and a fixing portion attached to a fishing rod and having a frame made of a fiber reinforced prepreg, the method comprising setting a laminate obtained by laminating a fiber reinforced prepreg in which a matrix resin is a thermoplastic resin in a mold, performing a primary processing treatment of pressing and fixing to form an outer shape of the frame having a planar portion, setting the laminate after the primary processing treatment in a mold different from the above mold, heating and pressing at a temperature at which the matrix resin becomes a plastic state to apply a shape change to the frame details to form a processing surface intersecting the extending direction of the planar portion, and performing a secondary processing treatment of curing at room temperature, and cutting out the frame from the laminate before or after the secondary processing treatment" has been proposed.

[0004] A method for manufacturing a fishing line guide comprising a ring-holding portion and a fixing portion for attachment to a fishing rod, and having a frame made of fiber-reinforced prepreg, is proposed (Patent No. 5460441), comprising: a primary processing treatment in which a laminated material made of fiber-reinforced prepreg, in which the matrix resin is a thermosetting resin, is set in a mold, and heated, pressurized, and fixed to form the outer shape of the frame having a planar portion, and a secondary processing treatment in which the laminated material processed in the primary processing treatment is set in a mold other than the mold, and heated and pressurized at a temperature higher than the heating temperature of the uncured state to change the shape of the details of the frame, thereby forming a processed surface that intersects the extension direction of the planar portion and fully curing, wherein the frame is cut out from the laminated material before or after the secondary processing treatment.

[0005] A method for manufacturing a fishing line guide has been proposed, comprising the steps of: arranging a fiber-reinforced synthetic resin material, which has reinforcing fibers and synthetic resin as matrix materials, in a groove for frame molding formed in a mold along its extension direction; and heat-molding the fiber-reinforced synthetic resin material, wherein the mold has a space for arranging a guide ring, and when arranging the fiber-reinforced synthetic resin material in a groove for frame molding formed in the mold along its extension direction, a guide ring is placed in the space and an anti-burr member is placed at the position where the guide ring is placed, and the guide ring is heat-molded together with the fiber-reinforced synthetic resin material under pressure.

[0006] A method for manufacturing a fishing line guide has been proposed, comprising the steps of: arranging a fiber-reinforced synthetic resin material, which has reinforcing fibers and synthetic resin as matrix materials, in a groove for frame molding formed in a mold along its extension direction; and heat molding the fiber-reinforced synthetic resin material, wherein the fiber-reinforced synthetic resin material is composed of a filamentous body in which a large number of reinforcing fibers are bundled together along the axial direction, and this is arranged along the extension direction of the groove in the mold, and the filamentous body is continuously arranged in a portion of at least two of the ring-holding portion, support leg portion, and fixing portion that constitute the frame.

[0007] A fishing line guide has been proposed (Patent No. 5514061) that "has a frame made of fiber-reinforced synthetic resin, and comprises a ring-holding portion for inserting a fishing line and a support leg portion for separating the fishing line from the surface of the fishing rod, wherein the frame has a portion on which reinforcing fibers of a thread-like body, in which a large number of reinforcing fibers are arranged in a bundle along the axial direction, are disposed."

[0037] [Figure 1] Perspective view from one side (front) of the fishing line guide according to the present invention. [Figure 2] Perspective view of the fishing line guide according to the present invention, from the other side (back). [Figure 3] Cross-sectional view of the fishing line guide according to the present invention [Figure 4] Cross-sectional view of the fishing line guide according to the present invention [Figure 5] Perspective view of the lower half of the mold [Figure 6] Perspective view of the upper half of the mold in an inverted state. [Modes for carrying out the invention]

[0038] Embodiments of the present invention will be described.

[0039] The first invention is a fishing tackle. The fishing tackle is, for example, a fishing line guide. The main body of the fishing line guide is made of a fiber-containing resin composition. The main body is equipped with ribs. Previous proposed fishing line guides did not have ribs (rib structure). In contrast, the present invention is provided with ribs (rib structure). This improves mechanical strength. Moreover, because it has ribs (rib structure), the fishing line guide of the present invention is lighter than previous fishing line guides.

[0040] The main body preferably includes a substantially ring-shaped portion through which a fishing line is inserted. The main body preferably includes a support portion for attaching the substantially ring-shaped portion to a fishing rod. The support portion preferably comprises a base (trunk) located on the fishing rod side. The support portion preferably comprises branch portions (branching portions: the tips of these branch portions (branching portions) connect to the ring-shaped portion) that branch off at the tip of the base (trunk). The aforementioned roughly ring-shaped portion may be annular, and may be circular, elliptical, or a polygon such as a triangle or quadrilateral. The aforementioned roughly ring-shaped portion may be partially interrupted (it may be an open annular shape (roughly C-shaped)), that is, it does not necessarily have to be a closed shape. However, it is generally a closed annular shape. The support portion is, for example, roughly Y-shaped. The tip of the branch (branch) of this roughly Y-shaped portion is connected to the roughly ring-shaped portion. The roughly Y-shaped portion supports the roughly ring-shaped portion. The roughly Y-shaped portion may also include the following case: The tip side of the roughly Y-shaped portion is roughly V-shaped. That is, there are two tips on the tip side, but there may be three or more. There can be any number of tips, but in reality it will probably be two or three. This is because the more tips there are, the heavier it becomes. When a force from the fishing line acts on the aforementioned roughly ring-shaped portion, this force acts on the tip of the support portion (branch portion) that supports the aforementioned roughly ring-shaped portion. Since there is not just one but multiple support portions (branch portions), that is, because the support portion (supporting tip) is roughly Y-shaped, the support portion is resistant to bending (twisting). Although it is resistant to bending (twisting), the mechanical strength of each support part (branch) is reduced because the tip of the support part (branch) is divided into, for example, two parts. Therefore, in order to compensate for the reduction in mechanical strength, it was decided to add ribs to the branch. The inner part of the branch is thin-walled. The outer part of the branch is thick-walled. The thick-walled part is the rib. The reason why the rib structure was preferred was as follows: The rib structure (i.e., a structure in which the ribs are located further out than in the inner part) had greater resistance to deformation pressure such as twisting than a rib structure in which the inner part of the branch was thick-walled and the outer part was thin-walled. The rib structure may be configured in locations other than the branching portion. For example, a rib may be formed in the substantially ring-shaped portion located between the branching portions. The outer ring portion of the substantially ring-shaped portion located between the branching portions is thin-walled, while the inner ring portion of the substantially ring-shaped portion is thick-walled. The thick-walled portion is the rib. Since the inner portion of the branching portion is made thin-walled, the outer ring portion is made thin-walled. The structure would become more complex if the order were reversed.

[0041] Preferably, the extension direction of the branch portion (branch) of the substantially Y-shaped portion was in a direction approximately tangential to the substantially ring-shaped portion. The reason for this is as follows: When the connection direction between the branch portion and the substantially ring-shaped portion is in a direction approximately tangential to the substantially ring-shaped portion, the branch portion can firmly withstand the force applied to the substantially ring-shaped portion. The width of the branch portion of the roughly Y-shaped section was preferably wider than the width of the roughly ring-shaped section. The reason for this is as follows: Increasing the width of the branch portion increases the mechanical strength of the branch portion, allowing it to easily withstand the force applied to the roughly ring-shaped section. The thickness of the ribs at the branching (branching) portion of the aforementioned roughly Y-shaped section was preferably approximately the same as the thickness of the aforementioned roughly ring-shaped section. The reason for this is as follows: By making them the same thickness, the structure was simplified. The width of the base (trunk: the part at the root from which the branched portion (branch portion) originates) of the roughly Y-shaped section preferably decreased almost monotonically from the tip (where the branched portions connect) to the base (bending position). The thickness of the base (trunk) of the roughly Y-shaped section preferably increased almost monotonically from the tip to the bending position. The reason for this is as follows: By increasing the thickness even when the width narrowed, the mechanical strength of the base (trunk) could be ensured. In other words, the base could firmly withstand the force applied to the roughly ring-shaped section. Preferably, the thickness of the base (trunk) of the aforementioned roughly Y-shaped section was such that it thinned from the point past the bend toward the base end. The reason for this is as follows: In order to make it easier to fix the base to the fishing rod, the thickness was made thinner from a point approximately midway between the bend and the base end toward the base end. The aforementioned fibers were located across the substantially ring-shaped portion and the substantially Y-shaped portion.

[0042] The structure of the fishing line guide may, as appropriate, adopt the content disclosed in Patent Document 1 (Japanese Patent No. 5460441) and Patent Document 2 (Japanese Patent No. 5514061). For example, the structure of the main body may, as necessary, adopt the content disclosed in Patent Document 1 and Patent Document 2. For example, a metal (e.g., Ti, Al, Mg, SUS, etc.) or ceramic ring may be provided on the substantially ring-shaped part. The base (main body) of the substantially Y-shaped part may be made into a structure that is easy to attach to a fishing rod, for example, a bent shape.

[0043] The fibers in the fiber-containing resin composition that constitutes the main body of the fishing line guide are reinforcing fibers. Examples of such fibers include inorganic fibers. Organic fibers may also be used. A combination of both may be used. The fibers only need to satisfy the following requirements: (length of 1 / 4 or more of the circumference of the substantially ring-shaped portion) ≤ (length of the fiber in the longitudinal direction). Or, (length of 1 / 2 or more of the length from the base end of the substantially Y-shaped portion to the end of one branch) ≤ (length of the fiber in the longitudinal direction). Preferably, (length from the base end of the substantially Y-shaped portion to surround a part of the circumference of the substantially ring-shaped portion) ≤ (length of the fiber in the longitudinal direction). Although it varies depending on the size of the main body, a specific value is, for example, 1 cm or more. Preferably, 2 cm or more. More preferably, 3 cm or more. Even more preferably, 6 cm or more. There are no particular restrictions on the average fiber length of the continuous reinforcing fibers used in the present invention, but from the viewpoint of improving moldability, a range of 0.05 to 20000 m was preferred. More preferably, 100 to 10000 m. More preferably, the length was 1000 to 7000 m. A combination of fiber lengths exceeding 3 cm (6 cm) and fiber lengths of 3 cm (6 cm) or less is also acceptable. Unless otherwise specified, the fiber length in this invention is the weight-average fiber length. The average fiber diameter of the fiber was preferably 3 μm or more. More preferably 4 μm or more. Even more preferably 5 μm or more. Preferably 50 μm or less. More preferably 20 μm or less. Even more preferably 12 μm or less. The average fiber diameter is the diameter of a single yarn.

[0044] Examples of the inorganic fibers include, but are not limited to, carbon fibers, silicon carbide fibers, alumina fibers, boron fibers, glass fibers, and metal fibers. Multiple types of fibers may be used in combination, rather than just one type. In addition, carbon fibers were preferred from the viewpoint of mechanical strength and lightness. Examples of the carbon fibers include polyacrylonitrile (PAN) carbon fibers, petroleum / coal pitch carbon fibers, rayon carbon fibers, cellulose carbon fibers, lignin carbon fibers, phenolic carbon fibers, and vapor-grown carbon fibers. One or more of these may be used as appropriate. Preferably, the carbon fibers used have a tensile modulus of 100 GPa to 1000 GPa. The form of the carbon fibers is not particularly limited. The carbon fibers may be continuous or discontinuous. Examples of continuous fibers include carbon fibers arranged in one direction (unidirectional material). Examples of discontinuous fibers include materials in which carbon fibers are arranged in a resin so as to be oriented in a specific direction, or materials in which carbon fibers are randomly dispersed in the in-plane direction. The carbon fibers may be in the form of single filaments, fiber bundles, or mixtures of both. Generally, carbon fibers are in the form of fiber bundles, consisting of several thousand to tens of thousands of filaments. When using carbon fiber bundles as carbon fibers, if the carbon fiber bundles are used as is, the entangled parts of the fiber bundles may become locally thicker, making it difficult to obtain carbon fiber reinforced resin processed products with thin-walled ends. Therefore, when using carbon fiber bundles as carbon fibers, it is preferable to widen or open the carbon fiber bundles before use. Examples of the aforementioned metal fibers include Al fibers, Au fibers, Ag fibers, Fe fibers, and stainless steel fibers. Examples of organic fibers include aramid fibers, aromatic polyamide fibers, cellulose fibers, polyethylene fibers, and poly(paraphenylenebenzobisoxazole) fibers (Zylon, manufactured by Toyobo Co., Ltd.). The fibers may be treated with a treatment agent. Examples of the treatment agent include sizing agents and surface treatment agents. For example, the treatment agent disclosed in Japanese Patent Publication No. 4894982 is an example. It is advantageous when the treatment agent on the fiber surface reacts with the functional groups (reactive groups: polar groups) of the resin. The treatment agent is selected from the group consisting of, for example, epoxy resin, urethane resin, silane coupling agent, water-insoluble polyamide resin, and water-soluble polyamide resin. Preferably, it is selected from the group consisting of epoxy resin, urethane resin, water-insoluble polyamide resin, and water-soluble polyamide resin. One type or two or more types may be used.

[0045] Various resins can be used as the resin for the fiber-containing resin composition that constitutes the main body of the fishing line guide. The main body is manufactured, for example, by additive manufacturing technology described later. Therefore, preferably, the resin is one that can be used in additive manufacturing technology (matrix resin). Examples of such resins include thermoplastic resins and thermosetting resins. Either one or the other may be used, or they may be used in combination. The resin may be of one type or two or more types. The resin may be in the form of a film (or sheet). The resin may be in the form of fibers (yarn or filament). If the resin is in the form of fibers, in this invention it is a so-called blended yarn (see, for example, WO2016 / 167136A1). In the case of a blended yarn, the technology disclosed in WO2016 / 167136A1 can be used. The resin is preferably one that has functional groups (reactive groups: polar groups). A resin without functional groups (reactive groups: polar groups) can also be used. Thermoplastic resins may consist solely of thermoplastic resin or have thermoplastic resin as the main component. In the present invention, either case is acceptable. In this specification, unless otherwise specified, the term thermoplastic resin includes both cases: cases consisting solely of thermoplastic resin and cases having thermoplastic resin as the main component. A thermoplastic resin as the main component means that the thermoplastic resin makes up 50% by mass or more. Preferably, it is 80% by mass or more. More preferably, it is 90% by mass or more. Thermosetting resins can consist solely of thermosetting resin or have thermosetting resin as the main component. In the present invention, either case is acceptable. In this specification, unless otherwise specified, the term "thermosetting resin" includes both cases: those consisting solely of thermosetting resin and those having thermosetting resin as the main component. A thermosetting resin as the main component means that the thermosetting resin accounts for 50% by mass or more. Preferably, it is 80% by mass or more. More preferably, it is 90% by mass or more. Examples of thermosetting resins include epoxy resins, vinyl ester resins, unsaturated polyester resins, diallyl phthalate resins, phenolic resins, maleimide resins, cyanate resins, benzoxazine resins, and dicyclopentadiene resins. Examples of thermoplastic resins include polyolefin resins, polystyrene resins, thermoplastic polyamide resins, polyester resins, polyacetal resins (polyoxymethylene resins), polycarbonate resins, (meth)acrylic resins, polyarylate resins, polyphenylene ether resins, polyimide resins, polyethernitrile resins, phenoxy resins, polyphenylene sulfide resins, polysulfone resins, polyketone resins, polyetherketone resins, thermoplastic urethane resins, fluoropolymer resins, and thermoplastic polybenzimidazole resins. Examples of the polyolefin resins include polyethylene resin, polypropylene resin, polybutadiene resin, polymethylpentene resin, vinyl chloride resin, vinylidene chloride resin, vinyl acetate resin, and polyvinyl alcohol resin. Examples of the aforementioned polystyrene resin include polystyrene resin, acrylonitrile-styrene resin (AS resin), and acrylonitrile-butadiene-styrene resin (ABS resin). Examples of the polyamide resin include polyamide 6 resin (nylon 6), polyamide 11 resin (nylon 11), polyamide 12 resin (nylon 12), polyamide 46 resin (nylon 46), polyamide 66 resin (nylon 66), and polyamide 610 resin (nylon 610). One of the polyamide resins mentioned above is nylon (hereinafter sometimes abbreviated as "PA"), which includes PA6 (also called polycaproamide, polycaprolactam, or poly-ε-caprolactam), PA26 (polyethylene adipamide), PA46 (polytetramethylene adipamide), PA66 (polyhexamethylene adipamide), PA69 (polyhexamethylene azepamide), PA610 (polyhexamethylene sevacamide), PA611 (polyhexamethylene undecamide), PA612 (polyhexamethylene dodecamide), PA11 (polyundecaneamide), PA12 (polydodecaneamide), PA1212 (polydodecamethylene dodecamide), PA6T (polyhexamethylene terephthalamide), P Examples include A6I (polyhexamethylene isophthalamide), PA912 (polynonameethylene dodecamide), PA1012 (polydecamethylene dodecamide), PA9T (polynonameethylene terephthalamide), PA9I (polynonameethylene isophthalamide), PA10T (polydecamethylene terephthalamide), PA10I (polydecamethylene isophthalamide), PA11T (polyundecamethylene terephthalamide), PA11I (polyundecamethylene isophthalamide), PA12T (polydodecamethylene terephthalamide), PA12I (polydodecamethylene isophthalamide), polyamide XD6 (polymetaxylylene adipamide), polyamide XD10 (polyxylylene sebaamide), etc. Examples of the aforementioned polyester resins include polyethylene terephthalate resin, polyethylene naphthalate resin, polybutylene terephthalate resin, polytrimethylene terephthalate resin, and liquid crystal polyester.

The resin used in the fiber-containing resin composition that constitutes the main body of the fishing line guide was preferably a thermosetting resin. Particularly preferred was a thermosetting resin with a water absorption rate of 2.0% or less.

[0046] From the viewpoint of lightweight properties and mechanical strength, the following ratios of resin to fiber in the fiber-containing resin composition constituting the main body of the fishing line guide were preferred. For example, a large amount of carbon fiber increased the mechanical strength, but resulted in a loss of lightweight properties. Conversely, a small amount of carbon fiber resulted in low mechanical strength. From this viewpoint, the preferred ratios of the two were as follows: Preferably, 20 / 100 ≤ (volume of resin) / (volume of fiber + volume of resin). More preferably, 25 / 100 ≤ (volume of resin) / (volume of fiber + volume of resin). Even more preferably, 30 / 100 ≤ (volume of resin) / (volume of fiber + volume of resin). Even more preferably, 35 / 100 ≤ (volume of resin) / (volume of fiber + volume of resin). Preferably, (volume of resin) / (volume of fiber + volume of resin) ≤ 55 / 100. More preferably, (volume of the resin) / (volume of the fibers + volume of the resin) ≤ 50 / 100. Even more preferably, (volume of the resin) / (volume of the fibers + volume of the resin) ≤ 45 / 100. Even more preferably, (volume of the resin) / (volume of the fibers + volume of the resin) ≤ 40 / 100.

[0047] The second invention is a method for manufacturing fishing tackle. For example, a method for manufacturing the fishing line guide. The method comprises a molding step in which a resin composition having fibers (for example, containing fibers) is formed using a 3D printer. The method comprises a heating and pressurizing step in which the molded object obtained in the molding step is heated and pressurized.

[0048] Additive manufacturing (3D printer manufacturing technology) is a well-known technology. This technology is described as follows in the "FY2013 Patent Application Technology Trend Survey Report (Summary) 3D Printer": 3D printing (additive manufacturing technology) refers to the process of creating an object from a three-dimensional numerical representation by attaching material. In many cases, this is achieved by stacking layers upon layers. The term 3D printing is used in contrast to the two-dimensional representation produced on paper. The term "additive manufacturing technology" is used in ASTM F2792-12a (Standard Terminology for Additive Manufacturing Technologies). Manufacturing three-dimensional (not sheet-like) fiber-reinforced resin products using only additive manufacturing techniques was extremely difficult. In particular, when the amount of fiber was increased as much as possible (relatively reducing the amount of resin) to improve mechanical strength, manufacturing such products using only additive manufacturing techniques was very challenging. Therefore, in manufacturing the aforementioned fishing tackle, it was decided to heat and pressurize the molded object created using additive manufacturing technology.

[0049] The molding process (additive manufacturing process) is a process in which additive manufacturing technology is used. In the additive manufacturing process, for example, an additive manufacturing apparatus equipped with a nozzle is used. In the process, resin (plastic) and fibers are used. In the process, the resin (resin that forms the matrix) and the fibers may be supplied (discharged) from separate nozzles. Each material may be supplied (discharged) simultaneously. They may be supplied (discharged) with a time difference. Fiber-reinforced plastic material (material in which fibers are dispersed in resin) may be supplied (discharged) from a single nozzle. By the process, a fiber-reinforced plastic product of a desired shape is obtained. In the additive manufacturing process, for example, additive manufacturing technology using fused deposition modeling may be used. The additive manufacturing process may include, for example, a coating and printing step in which an unsolidified coagulant is applied and printed onto the upper surface of a laminate or onto a sheet surface to be bonded to the laminate, based on laminate region data in a predetermined cross-section of a three-dimensional model, and a bonding step in which the sheet with the unsolidified coagulant applied and printed on it is superimposed and bonded to the laminate in a heat-retaining state, or an additive manufacturing technique may be used that does not include a bonding step in which sheets with a coagulant selectively applied to their surface are laminated and the sheets are selectively bonded to each other by the coagulant, and an additive manufacturing technique may be used in which fibers and resin are used for molding. The fishing tackle (for example, the fishing line guide) may be molded by a single (one) additive manufacturing process. Product A may be a combination of parts A1, ..., Ak (where k is an integer less than or equal to n), ..., and An (where n is an integer greater than or equal to 2). In such cases, part A1 is formed by one (one) additive manufacturing process A1. Similarly, part Ak is formed by one (one) additive manufacturing process Ak. Part An is formed by one (one) additive manufacturing process An. When parts A1, ..., Ak, ..., An formed by additive manufacturing processes A1, ..., Ak, ..., An are combined, the resulting combination will have the same shape as product A.In other words, the additive manufacturing process may be completed in one step or in two or more steps. Either approach may be adopted.

[0050] In the molding process (additive manufacturing process), when the resin is a thermosetting resin, a temperature of 0°C or higher was preferred from the viewpoint of moldability. More preferably, it was 10°C or higher. Even more preferably, it was 20°C or higher. Even more preferably, it was 30°C or higher. A temperature of 350°C or lower was preferred. Even more preferably, it was 150°C or lower. Even more preferably, it was 100°C or lower. When the resin is a thermoplastic resin, from the viewpoint of moldability, a temperature of 30°C or higher was preferred. Even more preferably, it was 50°C or higher. Even more preferably, it was 100°C or higher. There are no particular restrictions on the upper limit. However, generally, a temperature of 700°C or lower was preferred. More preferably, it was 500°C or lower. Even more preferably, it was 450°C or lower. Even more preferably, it was 400°C or lower.

[0051] The product obtained through the additive manufacturing process was substantially flat. It was not a three-dimensional shape (solid shape). For example, it was not a solid shape having a flat surface and an intersecting surface that intersects the flat surface. It was not easy to obtain a three-dimensional shape (solid shape) product using additive manufacturing alone. It was easy (relatively easy) to obtain a substantially flat product using additive manufacturing. Because the product obtained through the additive manufacturing process had many fibers, not all of the fibers were integrally (rigidly) bonded by the resin. In the product, the fibers were partially separated. The fibers were only loosely connected. This separation means that the product (the product obtained through the additive manufacturing process) is not a fixed single shape. For example, if a force such as bending it into a roughly bow shape is applied to the product, the fibers will shift position. If all of the fibers were integrally (strongly) bonded by the resin, the fibers would not shift position even if such a force were applied to the product. Of course, this is different if you apply a force large enough to destroy it.

[0052] The pressurization step (heating and pressurization step) is preferably a step in which the molded object, which has been placed in a mold and heated, is pressurized. The pressurization step may be performed in multiple stages. For example, it may be performed in two stages, such as a first pressurization step and a second pressurization step. The first pressurization step is performed at a relatively small pressure. The second pressurization step (second pressurization step) is performed at a larger pressure than the first pressurization step (first pressurization step). The change in pressurization force from small to large in the pressurization step may be in a step function or continuous. In other words, the pressurization force may gradually increase. Such a pressurization method is also considered to be performed in multiple stages. The first pressurization step is a step in which the product obtained through the additive manufacturing technology step is pressurized. In the first pressurization step, most of the fibers are integrally bonded by the resin. That is, the fibers are bonded to a certain extent firmly and integrally by the resin. When the fibers are integrally bonded by the resin, even if a large force is applied to the product, the fibers are less likely to shift position. Even if a large force is applied to a product that has undergone the first pressing process, the product is less likely to deform. Of course, this is not the case if a force large enough to cause destruction is applied. In contrast, when a large force is applied to a product obtained at the stage obtained through the additive manufacturing process, there was a risk of displacement of the fibers. The product obtained through the first pressing process has curved parts. Therefore, the shape of the product was three-dimensional. In contrast, the product obtained at the stage obtained through the additive manufacturing process is flat. Therefore, at this stage, the product does not have curved parts (surfaces intersecting a plane). In the first pressing process, a two-dimensional product is molded into a three-dimensional product. If the force applied in the first pressing process is too large, the fibers in the product obtained through the additive manufacturing process are not firmly integrated with the resin, so deformation is likely to occur. For this reason, it was preferable not to apply too large a force. In other words, the force applied in the first pressing process is smaller than the force applied to create the final product shape. In the first pressurization step, multiple products obtained through the additive manufacturing process may be stacked and pressed together. Of course, in some cases, only one product may be pressed.The second pressurization step is a step in which the product obtained through the first pressurization step is pressurized under heating. The force applied in the second pressurization step is greater than the force applied in the first pressurization step. That is, the force applied in the second pressurization step is the force applied to give the product its final shape. The volume of the product obtained through the second pressurization step is smaller than the volume of the product obtained through the first pressurization step. The pressure in the first pressurization step is less than the pressure in the second pressurization step. For example, (pressure in the first pressurization step) / (pressure in the second pressurization step) was 0.8 or less. For example, it was 0.7 or less. For example, it was 0.6 or less. For example, it was 0.5 or less. For example, it was 0.4 or less. For example, it was 0.02 or more. For example, it was 0.05 or more. For example, it was 0.1 or more. The pressure in the first pressurization step was 0.8 kPa or more. For example, it was 4 kPa or more. For example, 8.0 × 10. 5 It was below kPa. For example, 4.0 × 10 5 It was less than or equal to kPa. The pressure in the second pressurization step was 1 kPa or more. For example, it was 5 kPa or more. For example, 1.0 × 10 6 It was below kPa. For example, 5.0 × 10 5 It was less than or equal to kPa. (Volume of product obtained after the first pressurization step) / (Volume of product obtained after the second pressurization step) ≤ 2.5. For example, it was 2 or less. For example, it was 1.5 or less. For example, it was 1.05 or more. For example, it was 1.1 or more.

[0053] The pressurization step is preferably carried out under heating conditions. This is because raising the temperature above room temperature (e.g., 25°C) softens the resin (resin composition). As a result, the moldability under pressurization is improved. The heating temperature should have met the following conditions: For example, the temperature was above the melting temperature when using the 1 / 2 method with a flow tester CFT-500D (manufactured by Shimadzu Corporation) in accordance with the manual included with the device. Preferably, the temperature was {the melting temperature + 10°C} or higher. More preferably, the temperature was {the melting temperature + 20°C} or higher. Preferably, the temperature was {the melting temperature + 60°C} or lower. More preferably, the temperature was {the melting temperature + 50°C} or lower. Even more preferably, the temperature was {the melting temperature + 40°C} or lower. Even more preferably, the temperature was {the melting temperature + 30°C} or lower. If the resin is a thermoplastic resin, then any temperature exceeding the melting temperature is acceptable. If the resin is a thermosetting resin, then, for example, a temperature below the curing temperature is sufficient. The aforementioned melting temperature is also called the softening point (softening temperature). The temperature was determined by the following method: A constant-load extrusion type capillary rheometer (flow characteristic evaluation device: Flow Tester CFT-500D (manufactured by Shimadzu Corporation)) was used, and the procedure was carried out according to the manual provided with the device. In this device, a constant load is applied from the top of the sample to be measured (in this case, the sample is a resin without fibers, not a resin with fibers). The sample to be measured, filled in the cylinder, is heated and melted. The molten sample to be measured is extruded from the die at the bottom of the cylinder. A flow curve showing the relationship between the piston descent amount and the temperature is obtained. The melting temperature in the 1 / 2 method described in the manual was calculated as follows: Half of the difference between the piston descent amount Smax at the end of outflow and the piston descent amount Smin at the start of outflow is determined (let this be X. X = (Smax - Smin) / 2). The temperature of the flow curve at the point when the piston descent amount becomes X is the melting temperature in the 1 / 2 method. For example, when the resin was epoxy resin (thermosetting resin), the melting temperature (softening temperature) determined by the above method was approximately 70°C. When the resin was benzoxazine (thermosetting resin), the melting temperature (softening temperature) determined by the above method was approximately 80°C. When the resin was cyanate resin (thermosetting resin), the melting temperature (softening temperature) determined by the above method was approximately 80°C. When the resin is a thermosetting resin, the heating temperature was preferably (resin curing temperature - 70°C) or higher. More preferably (resin curing temperature - 60°C) or higher. Even more preferably (resin curing temperature - 50°C) or higher. Even more preferably (resin curing temperature - 40°C) or higher. Preferably (resin curing temperature + 20°C) or lower. Even more preferably (resin curing temperature + 10°C) or lower. Most preferably (resin curing temperature or lower). The curing temperature is the peak temperature in the DSC curve. The thermosetting temperature of epoxy resin (thermosetting resin) is approximately 120-180°C. The thermosetting temperature of benzoxazine resin (thermosetting resin) is approximately 120-200°C. The thermosetting temperature of cyanate resin (thermosetting resin) is approximately 150-250°C. If the resin is a thermosetting resin, after-curing may be performed.

[0054] A mold is used in the pressing process. The mold comprises mold half A and mold half B. Mold half A and mold half B each have recesses (grooves) formed on their opposing surfaces, which have a concave surface and no corners. The molded product obtained in the additive manufacturing process is placed in the recess of mold half A. Mold half B is placed over it and pressurized. When mold half A and mold half B are combined, the space (cavity) formed by the recesses of mold half A and B is the shape of the final product. The inner surface of the recess (groove) has no corners. Therefore, the product obtained by applying pressure between mold half A and mold half B has no corners because the inner surface of the recess (groove) has no corners. If the cavity consists only of a groove formed on the upper surface of the mold half A (where the mold half B opposite the recess (groove) of the mold half A has a protrusion or is flat), then even if the groove has no corners, the product obtained in this way will have corners.

[0055] The present invention will be described in detail below. The following examples are merely one embodiment of the present invention. The present invention is not limited to the following examples. In other words, modified and applied examples that do not significantly impair the features of the present invention are also included in the present invention.

[0056] [Example 1] A thermosetting resin (benzoxazine resin: manufactured by Aica Kogyo Co., Ltd.) was used. Carbon fiber (manufactured by Mitsubishi Rayon Co., Ltd., Pyrofil-TR-50S-12000-AD, 8000 dtex, 12000 fiber count, fiber length 6 m) was also used. The mixing ratio was 40 parts by volume of the resin and 60 parts by volume of the carbon fiber.

[0057] A 3D printer (Velleman K8200) was used. Additive manufacturing technology was performed (nozzle temperature: 135°C, stage temperature: 50°C). This resulted in the production of product X made of the aforementioned composition. Product X obtained through the additive manufacturing process is substantially flat. It is not three-dimensional (solid). Because the amount of resin in product X is relatively small, not all of the fibers are integrally bonded by the resin. The fibers in product X were partially separated.

[0058] The product X obtained through the additive manufacturing process described above was placed inside the mold. First, 1.5 × 10 3 A pressure of kPa was applied. The molded product Y, after being pressurized, was removed from the mold and placed in the die. The die comprises a metal die half A (see Figure 5) and a metal die half B (see Figure 6). Grooves (recesses) 11 and 12 are formed on the surfaces of the die halves A and B. The shape of the space (cavity) formed by the grooves (recesses) 11 and 12 when the die halves A and B are joined together is the shape of the final product Z. The concave surfaces of the grooves (recesses) 11 and 12 have no corners. The removed molded product Y was first placed in the groove (recess) 11 of the die half A. The die half B was placed over the die half A in which the molded product Y was placed. Half of the molded product Y is located in the groove 11 of the die half A, and the remaining half of the molded product Y is located in the groove 12 of the die half B. 6.0 × 10 when heated to 180℃ 4 A pressure of kPa was applied to the molded product Y.

[0059] The fishing line guide Z obtained in this way is shown in Figures 1, 2, 3, and 4. Figure 1 is a perspective view of the fishing line guide Z. Figure 2 is a perspective view of the fishing line guide Z from the opposite side to that shown in Figure 1. Figure 3 is a cross-sectional view of the fishing line guide Z in the state shown in Figure 1, taken along a line connecting the vertex of the substantially ring-shaped portion 1 of the fishing line guide Z and the base end portion 3f of the substantially Y-shaped portion 2. Figure 4 is a cross-sectional view of the fishing line guide Z taken along a line perpendicular to the cross-sectional line in Figure 3, crossing the opening 6 of the fishing line guide Z. In each figure, 1 is the roughly ring-shaped section through which the fishing line will be passed (inner diameter of the ring: approximately 20.5 mm, outer diameter of the ring: approximately 23.7 mm, thickness: approximately 2.3 mm, width: approximately 1.6 mm).

[0060] 2 is a roughly Y-shaped section. The tip of the roughly Y-shaped section 2 has a branched structure. That is, the roughly Y-shaped section 2 has two branch sections 2a and 2b at its tip. The tips 3a and 3b of the branch sections 2a and 2b are connected to the roughly ring-shaped section 1. The direction of extension of the branch sections 2a and 2b is the tangential direction to the roughly ring-shaped section 1. Since the connection direction between the branch sections 2a and 2b and the roughly ring-shaped section 1 is approximately the tangential direction to the roughly ring-shaped section 1, the branch sections 2a and 2b were able to withstand the force applied to the roughly ring-shaped section 1 without difficulty. The base (trunk) 2c of the roughly Y-shaped section 2 is a single trunk. The intersection point 3c of the branch section 2a and the branch section 2b is the tip of the base (trunk) 2c.

[0061] The roughly ring-shaped portion 1 and the roughly Y-shaped portion 2 are integrally constructed. This can be understood from the fact that the product X was obtained by additive manufacturing technology. Some carbon fibers dispersed in the thermosetting resin are longer than {(circumference of the roughly ring-shaped portion 1) + (length of the roughly Y-shaped portion 2)}. Therefore, some carbon fibers will exist spanning both the roughly ring-shaped portion 1 and the roughly Y-shaped portion 2.

[0062] The branched sections 2a and 2b are slightly bent at an intermediate position 3d (for example, about 2 / 3 of the total length from the tip sections 3a and 3b) (opening angle is, for example, about 160-175° (for example, 170°)). The base section 2c is bent at an intermediate position 3e (opening angle is, for example, about 125-145° (for example, 135°)). The length of the branched sections 2a and 2b is about 40 mm. The width of the branched sections 2a and 2b is made larger than the width of the ring-shaped section 1 so that the ring-shaped section 1 can be firmly supported even if the thickness of the thickened section of the branched sections 2a and 2b is about the same as the thickness of the ring-shaped section 1. The width of the branched sections 2a and 2b is about 3.2 mm. The thickness of the thickened section of the branched sections 2a and 2b is about 2.3 mm. The thickness of the thinned section of the branched sections 2a and 2b is about 1 mm. The length of the base 2c is approximately 35 mm. The width of the base 2c at its tip (the intersection of branch 2a and branch 2b) 3c is approximately 7 mm. The width of the base (trunk) 2c at the bending position 3e is approximately 4.6 mm. The thickness of the base 2c at its tip 3c is approximately 2.5 mm. The thickness of the base 2c at the bending position 3e is approximately 2.7 mm. The thickness of the base 2c at its base end 3f is approximately 1 mm. The width of the base 2c decreases almost monotonically from the tip 3c to the base end 3f. The thickness of the base 2c increases monotonically from the tip 3c to the bending position 3e. The reason for increasing the thickness is to ensure the mechanical strength of the base 2c, as the width of the base 2c is gradually narrowed. The thickness decreases from the bending position 3e to the base end 3f. However, the rate of decrease from approximately midway between the bending position 3e and the base end 3f to the base end 3f increases rapidly. The thickness of the base portion 2c at the point where it is attached to the fishing rod (approximately midway between the bending point 3e and the base end portion 3f, extending to the base end portion 3f) has been reduced to facilitate attachment to the fishing rod.

[0063] 4a and 4b are the thickened sections (ribs) in the branching sections 2a and 2b. 5a and 5b are the thinned sections in the branching sections 2a and 2b. The thickened sections (ribs) 4a and 4b are located on the outside of the branching sections 2a and 2b. The thinned sections 5a and 5b are located on the inside of the branching sections 2a and 2b (on the side of the opening 6 formed by the branching sections 2a and 2b). The meaning of "thickness" in the thickened sections is that they are "thicker" than the "thickness" of the thinned sections. The thickness of the thickened sections (ribs) 4a and 4b is the aforementioned thickness in the branching sections 2a and 2b (approximately 2.3 mm). The width of the thickened sections (ribs) 4a and 4b is approximately 1 mm. The width of the thinned sections 5a and 5b is approximately 2.2 mm.

[0064] A thin-walled section was also formed in the roughly ring-shaped section 1. A thin-walled section 7a was formed in the roughly ring-shaped section 1 at the position between the branched sections 2a and 2b. The width of the thin-walled section 7a is approximately 1 mm. The width of the thick-walled section 7b is approximately 0.6 mm. The thickness of the thick-walled section 7b is approximately 2.3 mm. The thickness of the thin-walled section 7a is approximately 1 mm.

[0065] [Comparative Example 1] In Example 1, no ribs were constructed. The presence of ribs allowed us to achieve weight reduction while maintaining the necessary rigidity. In other words, when comparing the fishing rod equipped with the fishing line guide of Example 1 with the fishing rod equipped with the fishing line guide of Comparative Example 1, the fishing rod equipped with the fishing line guide of Example 1 was significantly easier to use.
