[0020] Hereinafter, an embodiment of a fishing rod according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are designated by the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for the sake of convenience.

[0021] 1 is a diagram showing one embodiment of a fishing rod according to the present invention. As shown in the figure, a fishing rod 1 according to one embodiment of the present invention comprises a rod body 2, a reel R attached to the rod body 2 via a reel seat 9, and a fishing line guide 10 attached to the rod body 2. In the illustrated embodiment, each of the reel seat 9 and the fishing line guide 10 corresponds to an attachment part attached to the outer circumferential surface of the rod body.

[0022] The rod body 2 is formed by connecting, for example, a butt rod 3, a middle rod 5, and a tip rod 7. These rod bodies are joined, for example, in a parallel joint. The butt rod 3, middle rod 5, and tip rod 7 can be joined by a telescoping type, a reverse parallel joint type, a spigot joint type, or any other known joint type. The rod body 2 may be formed from a single rod body.

[0023] The base rod 3, the middle rod 5, and the tip rod 7 are each formed of, for example, a tubular body made of fiber-reinforced resin. This tubular body made of fiber-reinforced resin is produced by winding a fiber-reinforced resin prepreg (prepreg sheet) in which reinforcing fibers are impregnated with a matrix resin around a core bar, and heating and curing the prepreg sheet. As the reinforcing fibers contained in the prepreg sheet, for example, carbon fiber, glass fiber, and any other known reinforcing fibers can be used. As the matrix resin contained in the prepreg sheet, a thermosetting resin such as an epoxy resin can be used. After the prepreg sheet is cured, the core bar is de-cored. In addition, the outer surface of the tubular body is appropriately polished. Each rod body may be formed in a solid shape.

[0024] In the illustrated embodiment, the butt rod 3, middle rod 5 and tip rod 7 are provided with a number of line guides 10 (line guides 10A-10D) that guide the fishing line that is let out from the reel 6 attached to the reel seat 9. More specifically, the butt rod 3 is provided with line guide 10A, the middle rod 5 is provided with line guide 10B, and the tip rod 7 is provided with line guide 10C. A top guide 10D is provided at the tip of the tip rod 7, but details will be omitted.

[0025] Next, referring to FIG. 2, the basic structure of the reel seat body 12 and the reel seat 9 will be described. Explain. Reel seat 9 The reel seat body 12 has a reel leg mounting surface 12a along its axial direction on which the reel leg 6a of the fishing reel 6 is mounted. The reel seat body 12 is formed in a cylindrical shape as a whole. The reel seat body 12 can be configured to have a length of, for example, 100 to 200 mm, but is not limited thereto.

[0026] In addition, the reel seat body 12 is slightly bulged on the side opposite the reel leg mounting surface 12a, and a bulged portion (trigger) 12b is formed with a curved outer surface that supports the ball of the foot or the area nearby when gripped with the hand to make it easy to grip.

[0027] The reel leg mounting surface 12a of the reel seat body 12 can be formed flat or approximately flat with a larger curvature than other circumferential portions (e.g., grip portion 12b) adjacent to the reel leg mounting surface 12a of the reel seat body 12, and is formed to extend in the axial direction of the reel seat body 12 shown in Fig. 2. A fixed hood 14 is integrally disposed at one end (rod base side) of the reel seat body 12. One end of the reel leg mounting surface 12a of the reel seat body 12 is disposed inside the fixed hood 14.

[0028] A movable hood 22 is attached to the other end (rod tip side) of the reel seat body 12 so as to be movable in the axial direction. The reel seat body 12 and the movable hood 22 are sometimes collectively referred to as the reel seat 9, but details will be omitted.

[0029] Next, a fishing rod handle member 20 according to one embodiment of the present invention will be described with reference to Fig. 3 (and Fig. 2). Here, the fishing rod handle member 20 is composed of the reel seat body 12 and the grip 4 formed adjacent to the reel seat body 12, and a connecting member may be provided between them as necessary. Note that the fishing rod handle member 20 can be called the fishing rod handle member 20 including the reel seat 9 and the grip 4, but this embodiment will be described as above.

[0030] As shown in the figure, in the fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12, in which the reel leg mounting portion 12a on which the reel leg 6b is mounted, and the grip 4 are formed as separate bodies. By forming the two as separate bodies in this way, it is advantageous in that it is possible to select an appropriate material and to easily expand the variation in shape. The reel seat body 12 and the grip 4 can be joined by adhesion, press-fitting (fitting) or screw fastening, but are not limited to these. In addition, in the fishing rod handle member according to one embodiment of the present invention, at least either the reel seat body or the grip is formed in part or in whole from carbon fiber reinforced plastic. In this way, it is possible to reduce costs by adopting an appropriate material or manufacturing method while maintaining the necessary functions. In addition, as shown in FIG. 4(b) described later, the fishing rod handle member 20 according to one embodiment of the present invention can be formed hollow. In this way, it is possible to significantly reduce the weight without affecting the sensitivity of the fishing rod.

[0031] In the fishing rod handle member 20 according to one embodiment of the present invention, at least one of the reel seat body and the grip may be made entirely or partially of carbon fiber reinforced plastic (CFRP). At least one of the reel seat body and the grip may be made entirely or partially of CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a hybrid. By making them of such materials, it is possible to suppress an increase in weight while ensuring sufficient rigidity and strength as the handle member 20 used for a fishing rod.

[0032] Next, with reference to FIG. 10, an embodiment of the fishing rod handle member 20 according to the present invention will be described in which the reel seat main body 12, on which the reel leg mounting portion 12a on which the reel leg 6b is mounted, is formed as a separate body from the grip 4.

[0033] First, in the example shown in FIG. 10(a), the reel seat body 12 is made of a resin material, and its end (the right end on the paper) is located 27 mm (to the right on the paper) behind the bulging portion (trigger) 12b in the axial direction of the reel seat body, and the grip 4 is connected to the end, and the grip is made of a fiber-reinforced plastic (FRP) material. One or more connecting members (not shown) may be provided between the reel seat body 12 and the grip 4. The material of the one or more connecting members may be configured similarly to the reel seat body 12 or the grip 4 (same below). Similarly, in the example shown in FIG. 10(b), the reel seat body 12 is made of a resin material, and its end (the right end on the paper) is inclined 27 mm (to the right on the paper) behind the bulging portion (trigger) 12b in the axial direction of the reel seat body, and the grip 4 is connected to the end, and the grip is made of a fiber-reinforced plastic (FRP) material. In addition, one or more connection members (not shown) may be provided between the reel seat body 12 and the grip 4.

[0034] 10(c), the reel seat body 12 is made of fiber reinforced plastic (FRP) material, and its end (the right end on the paper) is located 13 mm (right on the paper) behind the bulge (trigger) 12b in the axial direction of the reel seat body, and the grip 4 is connected to the end, and the grip is composed of a front part 26 and a rear part 27, the front part 26 is made of fiber reinforced plastic (FRP) material, and the rear part is made of a resin material. Note that one or more connecting parts (not shown) may be further provided between the front part 26 and the rear part 27. In the example shown in Fig. 10(d), the reel seat body 12 is made of a resin material, and its end (the end in the right direction of the paper) is located 13 mm (the right direction of the paper) behind the bulging part (trigger) 12b in the axial direction of the reel seat body, and the grip 4 is connected to the end, and the grip is composed of a front part 28 and a rear part 29, and both the front part 28 and the rear part 29 are made of a fiber reinforced plastic (FRP) material. Note that one or more connecting parts (not shown) may be further provided between the front part 28 and the rear part 29. Here, various shapes, structures, materials, and dimensions of the reel seat body 12 and the grip 4 are conceivable, and it is not intended to limit them to a specific embodiment.

[0035] Next, with reference to FIG. 12, we will explain another aspect of the fishing rod handle member 20 according to one embodiment of the present invention, in which the reel seat body 12, on which the reel leg mounting portion 12a on which the reel leg 6b is mounted, and the grip 4 are formed as separate bodies.

[0036] In the example shown in FIG. 12, the reel seat body 12 is made of a resin material, and the bulge (trigger ) 12b, 13 mm behind it (to the right of the page) in the axial direction of the reel seat body. The front part 30 of the grip 4 is connected to the end part (the right end part of the drawing), and the front part 30 of the grip 4 is connected to the end part. The front part 30 is connected to the rear part 31 via a connecting part. The grip 4 is, for example, The reel seat body 12 is made of fiber reinforced plastic (FRP) material. The material of the fourth part is not limited to resin material or fiber reinforced plastic (FRP). The reel seat body 12 and the rear portion 31 may be made of the same or different materials. If the front portion 30 and the rear portion 31 are made of the same material, they may be molded as a single unit. In the example shown in FIG. 12, the rod body (Main rod) That is, in the example shown in FIG. (Main rod) is formed so as to pass from the left side of the page through the inside of the reel seat body 12 and the front part 30 of the grip 4 (i.e., these members are formed hollow), be exposed from the right end of the front part 30 as viewed from the page, and be inserted into the rear part 31 of the grip 4 (i.e., the rear part 31 is formed at least partially hollow). In this way, the distance between the front and rear parts can be freely set, different materials can be appropriately selected for the front and rear parts, the size of each part can be made smaller than in the case of integral molding, and molding is facilitated (this is true throughout this specification).

[0037] Next, a fishing rod handle member 20 according to one embodiment of the present invention will be described with reference to Figs. 4(a) and (b). As shown in the figures, the fishing rod handle member 20 according to one embodiment of the present invention includes a reel seat body 12 in which a reel leg placement portion 12a on which a reel leg 6b is placed is formed, and a grip 4 connected to the reel seat body 12. The reel seat body has a grip portion 21 in a range from 40 mm forward of the bulging portion (trigger) 12b to 100 mm (X) backward as viewed in the axial direction of the reel seat body, and a first portion 23 occupying at least 10° of the upper half of the grip portion 21 is configured to be a flat surface (in the illustrated example, the first portion 23 is a flat surface) or a curved surface having a larger radius of curvature than the other second portion 24 as viewed in the circumferential direction of the reel seat body. Here, the front of the bulging portion (trigger) 12b refers to the side on which the above-mentioned fishing rod body is attached, and the rear of the bulging portion (trigger) 12b refers to the side on which the above-mentioned fishing rod body is attached.

[0038] According to the fishing rod handle member 20 of the embodiment of the present invention, the reel seat body and the grip constituting the handle member can be formed in a desired shape, and the gripping ability when gripping the reel seat body can be significantly improved. grasping It has been found that by arranging a surface formed of a straight line or a curved surface close to a straight line at the part where the fingertips touch when the fishing rod is held, it functions to prevent rotation in the direction of rotation around the axial length of the grip part, which leads to a significant improvement in gripping ability. Here, when the angler holds the grip part of the fishing rod, it has been found that, considering the expected outer diameter of the grip part (for example, φ20 to 27 mm, but not limited thereto) and the width of the angler's fingers (10 to 19 mm), it is preferable that the ratio required for the fingers to exert the anti-rotation effect is at least 10° or more in the circumferential angle of the upper half of the grip part 21. It has also been found that it is even better if the central part of the grip part where the fingers touch (the central part where the fingers touch when viewed in the axial direction of the grip part, for example, the part 30 mm forward to 80 mm backward of the bulge part 12b) is 30° or more.

[0039] The fishing rod handle member 20 according to one embodiment of the present invention is configured such that the radius of curvature of the curved surface of the first portion 23 (a pair (two) of the first portions 23 are formed in the example shown in FIG. 4(b)) occupying at least 10° of the upper half of the grip portion 21 is R20 or more or -R30 or less. The number of the first portions 23 may be two as shown in FIG. 4(b), or one or three or more may be provided (the same applies throughout this specification). In this way, the transition portion between the first portion and the second portion can exert a rotation-stopping effect from the fingertips to the vicinity of the first joint when the fishing rod handle is gripped, so that the gripping ability can be significantly improved. In addition, the fishing rod handle member according to one embodiment of the present invention is configured such that the radius of curvature of the other second portion 24 (the lower half shown in FIG. 4(b)) is R13 or more and less than R20.

[0040] The fishing rod handle member according to one embodiment of the present invention is configured to have a transition portion between a first portion of the upper half of the grip and the other second portion. In addition, in the fishing rod handle member according to one embodiment of the present invention, the transition portion is an inflection curve (not shown) or an inflection surface (a cross section of an inflection surface 25 shown in FIG. 5 described later), and in the case of the inflection surface, the plane or the radius of curvature is in the range of R0.1 to R1.0. In this way, the transition portion plays a role of biting into (fitting into) the knuckles and exerting a rotation-stopping effect, so that it is possible to greatly improve the gripping ability.

[0041] In the fishing rod handle member according to one embodiment of the present invention, the grip is and a gripping portion is provided within a range of 100 mm (Y) from the rear end of the gripping portion, and at least the upper half of the gripping portion is The first portion, which occupies 10° in both cases, has a radius of curvature of 10° in the plane or in the circumferential direction of the grip. Larger than the other second part song It is configured to be a surface.

[0042] According to the fishing rod handle member 20 of the embodiment of the present invention, the reel seat body and the grip constituting the handle member can be formed into desired shapes, and the gripping ability when the reel seat body is gripped can be significantly improved. In this way, it has been found that by arranging a surface formed of a straight line or a curved surface close to a straight line at the part where the fingertips touch when gripping the grip, the grip has a function of preventing rotation in the direction of rotation about the axial length of the grip as the center of rotation, which leads to a significant improvement in gripping ability. Here, when the angler grips the fishing rod when gripping the fishing rod, it has been found that the ratio required for the rotation prevention effect of the fingers to be exerted is at least 10° or more in the circumferential angle of the upper half of the grip portion 21, taking into consideration the expected grip outer diameter (for example, φ20 to 27 mm, but not limited thereto) and the width of the angler's fingers (10 to 19 mm), it is preferable that the grip has a circumferential angle of at least 10° or more. It has also been found that in the portion of the grip where the fingers come into contact (for example, the portion of the grip in the range of 0 mm to 80 mm from the rear end in the axial direction), it is even better if the angle is 30° or more.

[0043] A fishing rod according to one embodiment of the present invention is configured to include a fishing rod handle member according to one embodiment of the present invention and a fishing rod body.

[0044] According to the fishing rod of the embodiment of the present invention, the reel seat body and the grip constituting the handle member can be formed into the desired shapes, and the gripping ability when holding the reel seat body can be significantly improved. In this way, by arranging the surface formed by a straight line or a curved surface close to a straight line at the part where the fingertips touch when holding the grip, it is possible to perform a rotation prevention function in the direction around the axial length of the grip as the rotation center, which leads to a significant improvement in gripping ability.

[0045] Next, with reference to Figs. 5-7, the grip portion 21 of the fishing rod handle member 20 according to one embodiment of the present invention will be described using its cross-sectional view (cross-section AA in Fig. 4(a)) (for convenience of description, the hollow portion is omitted). The same applies to the grip portion of the grip 4, but the grip portion 21 of the reel seat body 20 will be described below as an example. Here, the position of the first portion in the axial direction of the fishing rod handle member 20 according to one embodiment of the present invention is not limited to the position of the cross-section AA in Fig. 4(a), and can be the position already described. In addition, the circumferential position (of the cross-section) at which the first portion of the fishing rod handle member 20 according to one embodiment of the present invention is formed may be the same regardless of the axial position of the grip portion 21, or may be different depending on the position.

[0046] First, Fig. 5(a) shows an example of a cross-sectional view of the grip portion 21 of a fishing rod handle member 20, and Fig. 5(b) shows an enlarged view thereof. As shown in the figure, in the fishing rod handle member 20 according to one embodiment of the present invention, at least 10° (angle α in the circumferential direction) of the upper half of the grip portion 21 is Occupy The first portion 23 (in the example shown in FIG. 5(a), a pair (two) of the first portions 23 are formed) is configured to be a flat surface (in the example shown in FIG. 5(a), the first portion 23 is a flat surface) or a curved surface having a larger radius of curvature in the circumferential direction of the reel seat body than the other second portions 24. Note that the circumferential angle (the angle occupied by the upper half) (of its cross section) occupied by the first portion in the fishing rod handle member 20 according to one embodiment of the present invention may be the same regardless of the position in the axial direction of the grip portion 21, or may be different depending on the position. As described above, when an angler holds a fishing rod by gripping the fishing rod, taking into consideration the expected grip outer diameter (for example, but not limited to, φ20 to 27 mm) and the width of the angler's fingers (10 to 19 mm), the ratio required for the anti-rotation effect provided by the fingers to be exerted should be at least 10° in the circumferential angle of the upper half of gripping portion 21, and the central portion where the fingers contact (the central portion where the fingers contact in the axial direction of the gripping portion, for example, the portion 30 mm forward to 80 mm rearward of bulge 12b) can be 30° or more.

[0047] Fig. 5(b) shows three profiles: the plane of Fig. 5(a) (A shown in Fig. 5(b)), B with a radius of curvature of R20, and C with a radius of curvature of -R30. It should be understood that the above-mentioned "large radius of curvature" means that the absolute value of the numerical value is large.

[0048] The first portion 23 shown in FIG. 5(b) is an example, and the radius of curvature of the curved surface of the first portion 23 (a pair (two) first portions 23 are formed in the example shown in FIG. 5(a)) occupying at least 10° of the upper half of the gripping portion 21 can be configured to be R20 or more or -R30 or less. The first portion 23 of the gripping portion 21 can be formed over an angle ranging from 5° to 45° in the circumferential direction of the upper half (40° (angle α) in the example shown in FIG. 5(a)). The angle can vary depending on the number of first portions 23 provided in the gripping portion 21. Between the first portion 23 and the second portion 24, an inflection curve (inflection point in cross section) or an inflection surface (curve in cross section) is formed as a transition portion, and the radius of curvature of the transition portion (inflection surface) is set to be in the range of R0.1 to R1.0. 5(a) and (b), an inflection surface 25 is formed, and the radius of curvature of the inflection is set in the range of R0.1 to R1.0. In this way, the shape is rounded rather than edgy so as not to injure the hand when gripping the glove, and the inflection surface 25 can bite into the knuckles to fit comfortably.

[0049] Here, the upper half refers to the portion of the grip part (as viewed in cross section) having an angle ranging from 0° to 180° as shown in FIG. 5(a). The lower half refers to the angle ranging from 180° to 360° as shown in FIG. 5(a). The other portion (second portion) 24 refers to a portion other than the first portion, but for convenience in this specification, it refers to the lower half. The angle range in which the first portion 23 is provided may be different or the same depending on the axial position of the fishing rod handle member 20. These are the same throughout this specification.

[0050] Next, Fig. 6 shows another example of a cross-sectional view of the grip portion 21 of the fishing rod handle member 20. As shown in the figure, the first portion 23 of the grip portion 21 can be formed over an angle ranging from 45 degrees to 90 degrees in the circumferential direction of the upper half (40° (angle β) in the example shown in Fig. 6). In the example shown, the first portion 23 is formed as a flat surface.

[0051] Next, Fig. 7 shows another example of a cross-sectional view of the grip portion 21 of the fishing rod handle member 20. As shown in the figure, the first portion 23 of the grip portion 21 can be formed over an angle ranging from 5 degrees to 60 degrees in the circumferential direction of the upper half (55° (angle γ) in the example shown in Fig. 7). In the example shown, the first portion 23 is formed into a curved surface with a radius of curvature of R20 or more or -R30 or less.

[0052] Next, FIG. 11 shows another example of a cross-sectional view of the grip portion 21 of the fishing rod handle member 20. As shown in FIG. 11(a) and (b), the first portion 23 of the grip portion 21 is composed of a portion 23A formed over an angle ranging from 5 degrees to 45 degrees in the circumferential direction of the upper half (40 degrees (angle α) in the example shown in FIG. 11) and a portion 23B formed over an angle ranging from 45 degrees to 90 degrees in the circumferential direction of the upper half (40 degrees (angle β) in the example shown in FIG. 11) (in the example shown, 23A and 23B are formed as a pair on the left and right (i.e., four portions in total)). In this way, the first portion 23 of the grip portion 21 is provided in two, and when formed as a pair, there are four in total. In this way, it is possible to further improve the anti-rotation effect when gripped. Here, the first portion 23 of the grip portion 21 is not limited to a specific embodiment, and various embodiments are possible. 11(b), a transition portion is formed between the portions 23A and 23B, but in FIG. 11(a), the portions 23A and 23B are formed continuously, and either mode can be selected as appropriate. In addition, when three first portions 23 are provided (for example, 23A, 23B, and 23C, although not shown), a transition portion can be formed between 23A and 23B, and a continuous portion can be formed between 23B and 23C.

[0053] As shown in FIGS. 4a and 4b, a fishing rod handle member 20 according to an embodiment of the present invention is In the fishing rod body of End but , and is configured to be attached to one end 15 of the reel seat body 12, the end 15 opposite the grip 4. By doing so, unlike many conventional methods, it is no longer necessary to pass the rod body through the entire or almost entire fishing rod handle member 20, which allows for a significant reduction in weight.

[0054] In the fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 The length (A) of the end 15 is configured to be 20-50 mm. As described above, it is no longer necessary to pass the rod body through the entire or substantially entire fishing rod handle member 20. Therefore, the weight can be significantly reduced. of End of The method of attachment to the fishing rod handle member 20 may be, for example, fitting (press-fitting), bonding, or fastening. but The above-mentioned mounting methods have the advantage that the rod body and the handle member can be attached and detached more easily.

[0055] Books In the fishing rod handle member 20 according to one embodiment of the invention, the fishing rod handle member is formed hollow, but the end 13 of the fishing rod body 3 may be provided with a circumferential rib in a region where the end 13 is attached to one end 15 of the reel seat body 12, the end 15 opposite the grip 4. In this way, it is possible to significantly reduce the weight without affecting the sensitivity of the fishing rod, and to increase the circumferential rigidity (crushing rigidity).

[0056] In the fishing rod handle member 20 according to one embodiment of the present invention, an inner layer (not shown) may be provided on the inside of the fishing rod handle member 20. In this case, a resin material can be used as the inner layer. In this way, it is possible to form a fishing rod handle member equipped with a reel seat that has high workability on the inner surface and is less susceptible to resin drying and fiber fuzz on the inner surface. More specifically, the presence of the inner layer on the inside of the fishing rod handle member 20 makes it possible to supply the necessary resin to the fibers, thereby stabilizing the physical properties (ensuring a lower limit of strength). In addition, when inserting or bonding a part into the inner layer, it may be necessary to perform additional processing on the inner diameter according to the dimensions of the part. If the inside is fuzzed, there is a problem that the processing allowance cannot be secured. However, the presence of the inner layer ensures a sufficient processing allowance, making it possible to mold a handle member with a more flexible and strong structure.

[0057] Next, referring to Figs. 8 and 9, a method for molding the reel seat body 12 and grip 4 of the fishing rod handle member 20 according to one embodiment of the present invention (when using carbon fiber reinforced plastic (CFRP)) will be described. First, as shown in Fig. 8a, the dimensions and shape of the core member are determined in accordance with the shape and dimensions of the reel seat body 12 of the fishing rod handle member 20 (for example, offset about 0.5-1 mm inward from the reel seat body 12), and a soluble core member is molded (molding of the core member). Possible methods for molding the core member include, but are not limited to, injection molding, casting, and formation using a 3D printer. The surface layer of the core member is covered with a non-soluble resin.

[0058] Next, as shown in Fig. 8b, prepregs are laminated around the core member to form a preform. Here, a dry carbon fiber base material not impregnated with resin may be used as the laminating material. Then, as shown in Fig. 8c, the preform is placed in a mold and pressurized under heat. Note that autoclave or RTM molding may be used, but is not limited to a specific embodiment.

[0059] Next, as shown in FIG. 8d, the molded product is subjected to secondary processing (dimension adjustment and deburring). More specifically, excess parts such as the front and rear of the molded product and burrs generated during molding are removed. Next, as shown in FIG. 8e, the molded product that has been subjected to secondary processing is put into water or warm water, etc., to dissolve the core member inside the molded product. In this manner, the reel seat body 12 is formed. After that, as shown in FIG. 8f, the outer surface of the reel seat body 12 is appropriately painted or printed. Then, as shown in FIG. 8g, parts for mounting the reel are attached. Finally, as shown in FIG. 8h, the reel can be placed and fixed on the reel seat body 12.

[0060] Next, as shown in Fig. 9a, the dimensions and shape of the core member are determined in accordance with the shape and dimensions of the grip 4 of the fishing rod handle member 20 (for example, offset about 0.5-1 mm inward from the grip 4), and a soluble core member is molded (molding of the core member). Possible methods for molding the core member include, but are not limited to, injection molding, casting, and molding with a 3D printer. The surface layer of the core member is covered with a non-soluble resin.

[0061] Next, as shown in Fig. 9b, a prepreg is laminated around the core member to form a preform. Here, a dry carbon fiber base material that is not impregnated with resin may be used as the lamination material.

[0062] 9c, the preform is placed in a mold and press-molded by heating and pressure, and may be molded in an autoclave or by RTM molding, but is not limited to a specific embodiment.

[0063] Next, as shown in Fig. 9d, the molded product is subjected to secondary processing (size adjustment and deburring). More specifically, excess parts at the front and rear of the molded product and burrs generated during molding are removed.

[0064] Next, as shown in Fig. 9e, the molded product that has been subjected to the secondary processing is put into water or warm water, etc., and the core member inside the molded product is dissolved. In this manner, the grip 4 is formed. After that, as shown in Fig. 9f, the outer surface of the fishing rod handle member 20 is appropriately painted or printed. Thereafter, by connecting a grip molded in the same manner to the reel seat main body molded as described above, the fishing rod handle member 20 according to one embodiment of the present invention can be formed.

[0065] In this manner, a fishing rod handle member 20 according to one embodiment of the present invention is formed, i.e., a fishing rod handle member 20 comprising a reel seat body 12 having a gripping portion and a reel leg mounting portion 12a on which the reel leg 6b is mounted, and a grip 4 connected to the reel seat body 12.

[0066] According to the fishing rod handle member 20 of one embodiment of the present invention formed in this manner, it is possible to form the reel seat body and grip that constitute the handle member into the desired shapes, while greatly improving the gripping ability when holding the reel seat body.

[0067] Next, another molding method for the fishing rod handle member 20 according to one embodiment of the present invention will be described. First, the dimensions and shape of the core member (for example, offset about 0.5-1 mm inward from the reel seat body and grip) are determined according to the shape and dimensions of the reel seat body and grip of the fishing rod handle member 20 (design of the core member). Using water-soluble sand, a sand-molded core member is formed according to the dimensions and shape of the core member.

[0068] Next, a preform is formed around the core member using carbon that is not impregnated with resin. Specifically, cross material (woven fabric), NCF (non-crimp fabric), braid (braided cord), and UD tape can be used, but are not limited to these. In addition, the carbon fiber needs to be shaped for the core member, and at that time, a binder is used to give it tackiness. The type of binder can be epoxy, rosin, polyamide, polyphenylene sulfide, polyetherimide, polyethersulfone, polysulfone, polyphenylene ether, polyimide, polyamideimide, phenoxy, etc., but are not limited to these. Here, in the above example, a case where carbon that is not impregnated with resin is used has been described, but a method in which a prepreg in which resin has been previously impregnated in carbon cloth or the like is directly laminated around the core by a hand lay-up method or the like and molded (cured) may also be used. The preform is set in a mold and resin is injected (RTM molding method). After that, the core member in the sand mold is removed underwater. Finally, the molded product is subjected to deburring, polishing, painting, etc. to form the reel seat body and grip.

[0069] In this RTM method, a low-viscosity resin is poured into the reel seat body. Even for complex shapes such as grips, resin withering, voids, and other unimpregnated areas are minimized. This has the advantage that it can be avoided. In addition, it uses a material that has better formability than prepreg. in tree This allows the fibers to be molded into complex shapes without placing excessive stress on them. Furthermore, since the exterior is formed by a mold and the interior is formed by a core material, It is possible to mold the inside and outside to the desired dimensions, and the molded products have good surface conditions. As described above, the RTM molding method has the advantage of stabilizing quality and avoiding insufficient strength. It becomes possible to do so.

[0070] Next, another molding method of the fishing rod handle member 20 according to one embodiment of the present invention will be briefly described. First, a mold molded to match the shape and dimensions of the reel seat body and the grip is prepared. Prepreg is placed in the mold as a preform, and a molded product is formed by pressing the prepreg against the outer mold in the mold by air pressure (internal pressure molding). After that, the molded product is subjected to deburring, polishing, painting, etc., to form the reel seat body and the grip. In such an internal pressure molding method, the prepreg is pressed against the mold (outer mold) by internal pressure to mold, so that the outer surface of the molded product can be molded better. In addition, the use of prepreg allows the production of a molded product with a relatively small amount of resin, making it possible to reduce the weight of the product.

[0071] The dimensions, materials, and arrangement of each component described in this specification are not limited to those explicitly described in the embodiments, and each component can be modified to have any dimensions, materials, and arrangement that can be included in the scope of the present invention. In addition, components not explicitly described in this specification can be added to the described embodiments, and some of the components described in each embodiment can be omitted.
