[0030] Hereinafter, embodiments of the fishing rod according to the present invention will be specifically described with reference to the drawings. In the plurality of drawings, the same reference numerals are assigned to common structural elements in the plurality of drawings. It should be noted that, for the sake of convenience of explanation, each drawing is not necessarily drawn to an accurate scale.

[0031] Figure 1 is a view showing an embodiment of the fishing rod of the present invention. As shown in the figure, a fishing rod 1 according to an embodiment of the present invention includes: a rod body 2; a reel R, which is installed on the rod body 2 via a reel seat 9; and a fishing line guide 10, which is installed on the rod body 2. In the illustrated embodiment, the reel seat 9 and the fishing line guide 10 respectively correspond to mounting members installed on the outer peripheral surface of the rod body.

[0032] The rod body 2 is constituted by connecting, for example, the butt rod 3, the middle rod 5, and the tip rod 7. These respective rod bodies are joined, for example, in a plug-in manner. The butt rod 3, the middle rod 5, and the tip rod 7 can be joined by an ejection method, a reverse plug-in method, a socketing method, or any known joining method other than these. The rod body 2 may also be constituted by a single rod body.

[0033] The butt rod 3, the middle rod 5, and the tip rod 7 are constituted by, for example, tubular bodies made of fiber-reinforced resin. The tubular body made of fiber-reinforced resin is manufactured by winding a fiber-reinforced resin prepreg (prepreg sheet) obtained by impregnating reinforcing fibers with a matrix resin around a mandrel and heating the prepreg sheet to cure it. As the reinforcing fibers contained in the prepreg sheet, for example, carbon fibers, glass fibers, 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 mandrel is removed. Moreover, the outer surface of the tubular body is appropriately polished. Each rod body may also be configured to be solid.

[0034] In the illustrated embodiment, a plurality of fishing line guides 10 (fishing line guides 10A to 10D) for guiding the fishing line released from the fishing reel 6 mounted on the reel seat 9 are provided on the butt rod 3, the middle rod 5, and the tip rod 7. More specifically, the fishing line guide 10A is provided on the butt rod 3, the fishing line guide 10B is provided on the middle rod 5, and the fishing line guide 10C is provided on the tip rod 7. A top guide 10D is provided at the tip of the tip rod 7, but detailed description thereof is omitted.

[0035] Next, Figure 2 the reel seat main body 12 and the reel seat 9 will be described. The reel seat 9 has a reel seat main body 12, and the reel seat main body 12 has a reel leg mounting surface 12a for mounting the reel leg 6a of the fishing reel 6 along its axial direction. The reel seat main body 12 is integrally formed in a tubular shape. The reel seat main body 12 can be configured to have a length of, for example, 60 mm to 160 mm, but is not limited thereto.

[0036] In addition, the reel seat main body 12 bulges slightly on the side opposite to the reel leg mounting surface 12a, and when held by the hand, a gripping portion 12b having an outer surface with a curved shape that is easy to grip is formed by supporting the thumb ball or its vicinity.

[0037] The reel leg mounting surface 12a of the reel seat main body 12 can be formed flat, or can be formed substantially flat with a curvature larger than that of other circumferential portions (for example, the gripping portion 12b) adjacent to the reel leg mounting surface 12a of the reel seat main body 12, and is formed along Figure 2The axially extended state of the spool seat main body 12 shown. A fixed cover 14 is integrally provided at one end (rod butt side) of the spool seat main body 12. One end of the spool leg placement surface 12a of the spool seat main body 12 is disposed inside the fixed cover 14.

[0038] A movable cover 22 is axially movably assembled at the other end (rod tip side) of the spool seat main body 12. Sometimes, the spool seat main body 12 and the movable cover 22 are collectively referred to as the spool seat 9, but detailed description thereof is omitted.

[0039] Next, with reference to Figure 3 (and Figure 2 ), a handle member 20 for a fishing rod according to an embodiment of the present invention will be described. Here, the handle member 20 for a fishing rod includes the aforementioned spool seat main body 12 and a grip 4 formed adjacent to the spool seat main body 12. Additionally, the aforementioned spool seat 9 and the grip 4 may be included and referred to as the handle member 20 for a fishing rod, but in this embodiment, it is defined as above.

[0040] As shown in the figure, in a handle member 20 for a fishing rod according to an embodiment of the present invention, the spool seat main body 12 having a spool leg placement portion 12a for placing the spool leg 6a and the grip 4 connected to the spool seat main body 12 are integrally formed. The outer layer 18 of the handle member for a fishing rod is formed of carbon fiber reinforced plastic, and its inner layer 17 is formed of resin. Additionally, the handle member 20 for a fishing rod according to an embodiment of the present invention is formed hollow.

[0041] Here, as the outer layer 18, CFRP or CFRTP may also be used, but it is not limited thereto. Additionally, as the inner layer 17, ABS, acrylic, PEI, or nylon can be used, but it is not limited thereto. The resin used for the inner layer 17 can be appropriately selected to have good affinity with the resin contained in the outer layer 18. In this way, the adhesion and bonding property between the outer layer 18 and the inner layer 17 can be improved.

[0042] According to the handle member 20 for a fishing rod according to an embodiment of the present invention, a handle member for a fishing rod having a spool seat with high processability of the inner surface, less likely to cause resin depletion, and no fiber burrs on the inner surface can be provided.

[0043] Next, with reference to Figure 4 in (a) of Figure 4 and (b) of

[0044] In the handle member 20 for a fishing rod according to an embodiment of the present invention, the handle member 20 for a fishing rod is configured to be formed of carbon fiber reinforced plastic (CFRP). Further, in this way, as the material of the outer layer 18 of the handle member 20 for a fishing rod, it may also be formed of CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a mixture. By forming with such materials, as the handle member 20 for a fishing rod, it is possible to suppress an increase in weight while ensuring sufficient rigidity and strength. Further, inside the outer layer 18 of the handle member 20 for a fishing rod, a resin material can be used as the inner layer 17. In this way, it is possible to form the handle member for a fishing rod of the spool seat having high workability of the inner surface, less likely to cause resin depletion, and no fiber burrs on the inner surface.

[0045] More specifically, in the case of only the outer layer 18, if the resin of the handle member becomes too little due to molding deviations caused by the core member, molding conditions, etc. described later, the physical properties related to strength will deteriorate. For example, the crushing strength of the annular portion decreases, or the handle is easily bent. On the contrary, by having the inner layer 17 inside the outer layer 18, it is possible to supply the necessary resin to the fibers, thereby stabilizing the physical properties (guaranteeing the lower limit of strength). Further, when inserting or bonding a member to the inner layer 17, additional processing of the inner diameter needs to be performed to match the size of the member, but if there are burrs on the inner side, there is a problem that the machining allowance cannot be ensured. On the contrary, as in the present invention, by having the inner layer 17 inside the outer layer 18, it is possible to sufficiently ensure the machining allowance, and thus it is possible to mold a handle member having a softer and stronger structure.

[0046] Further, as Figure 4 shown in (a) of Figure 4 and (b) of

[0047] In the handle member 20 for a fishing rod according to an embodiment of the present invention, the length (A) of the end portion 15 of the spool seat main body 12 is configured to be 20 - 50 mm. Thus, as described above, since it is not necessary to pass the rod body through the entire or substantially the entire handle member 20 for a fishing rod, a significant reduction in weight can be achieved.

[0048] Here, for the method of attaching the end portion 13 of the rod body 3 of the fishing rod to the fishing rod handle member 20, for example, fitting (pressing in), adhesion, or fastening is considered, but it is not limited thereto. According to the attachment methods listed herein, there is an advantage that the attachment and detachment of the rod body and the handle member become easier.

[0049] Next, with reference to Figure 5 , the fishing rod handle member 20 of an embodiment of the present invention will be described. As shown in the figure, in the fishing rod handle member 20 of an embodiment of the present invention, the fishing rod handle member is formed hollow, but it may have a circumferential rib in a region where the end portion 13 of the rod body 3 of the fishing rod is attached to the end portion 15 on the side opposite to the handle 4 of the end portion 15 of the reel seat main body 12. In this way, the weight can be significantly reduced without affecting the sensitivity of the fishing rod, and the circumferential rigidity (crushing rigidity) can be improved.

[0050] The fishing rod 1 of an embodiment of the present invention is configured to include any of the above-described fishing rod handle members 20 and the rod body 3. According to the fishing rod 1 of an embodiment of the present invention, a fishing rod with high workability of the inner surface, less likely to cause resin exhaustion, and no fiber burrs on the inner surface can be provided.

[0051] The fishing rod reel seat main body 12 of an embodiment of the present invention is a reel seat main body 12 having the rod body 3 of the fishing rod attached to one end and the fishing rod handle 4 attached to the other end. It has a reel leg placement portion 12a for placing the reel leg 6a. The entire fishing rod reel seat main body 12 is integrally formed. The outer layer 18 of the fishing rod reel seat main body 12 is formed of carbon fiber reinforced plastic, and the inner layer 17 of the fishing rod reel seat main body 12 is formed of resin. In addition, the reel seat main body 12 of an embodiment of the present invention is formed hollow.

[0052] According to the fishing rod reel seat main body 12 of an embodiment of the present invention, a reel seat main body 12 with high workability of the inner surface, less likely to cause resin exhaustion, and no fiber burrs on the inner surface can be provided.

[0053] In the fishing rod handle member 20 of an embodiment of the present invention, the carbon fibers of the carbon fiber reinforced plastic (CFRP) are configured to be continuously formed along the length direction of the fishing rod handle portion. Thereby, weight reduction can be achieved by ensuring bending rigidity, and the vibration of the rod caused by a fish biting can be sensitively transmitted to the hand.

[0054] Next, with reference to Figure 5 , the molding method of the fishing rod handle member 20 of an embodiment of the present invention will be described. First, as Figure 5As shown in (a) of [Figure 0], the size and shape of the core component are determined according to the shape and size of the handle component 20 for fishing rods (for example, offset about 0.5 - 1 mm inward from the handle component 20 for fishing rods), and the soluble core component is shaped (shaping of the core component). The shaping method of this core component can consider injection molding, injection molding, formation using a 3D printer, etc., but is not limited to this. It should be noted that the surface layer of the core component is covered with a non-soluble resin.

[0055] Next, as Figure 5 shown in (b) of [Figure 0], prepreg is laminated around this core component to form a preform. Here, as the laminated material, a dry carbon fiber base material not impregnated with resin can also be used.

[0056] Then, as Figure 5 shown in (c) of [Figure 0], this preform is placed in a mold, heated, and pressed to perform stamping molding. In addition, it can also be autoclave molding, RTM molding, etc., but is not limited to a specific method.

[0057] Next, as Figure 5 shown in (d) of [Figure 0], secondary processing (size adjustment, deburring) is performed on the molded product. More specifically, redundant parts such as the front and back of the molded product and burrs generated during molding are removed.

[0058] Next, as Figure 5 shown in (e) of [Figure 0], the molded product after secondary processing is put into water, warm water, etc., to dissolve the core component located inside the molded product. In this way, the handle component 20 for fishing rods is formed. Then, as Figure 5 shown in (f) of [Figure 0], painting or printing is appropriately performed on the outer surface of this handle component 20 for fishing rods. Then, as Figure 5 shown in (g) of [Figure 0], components for mounting a reel, etc., are installed. Finally, as Figure 5 shown in (h) of [Figure 0], a reel can be placed and fixed on this handle component 20 for fishing rods.

[0059] In this way, the handle component 20 for fishing rods of one embodiment of the present invention is formed, that is, a handle component 20 for fishing rods is formed, in which a reel seat main body 12 having a reel leg placement portion 12a for placing the reel leg 6a and a handle 4 connected to the reel seat main body 12 are integrally molded. The outer layer 18 of this handle component 20 for fishing rods is formed of carbon fiber reinforced plastic, and the inner layer 17 of this handle component 20 for fishing rods is formed of resin. Here, the inner layer 17 is formed by making the non-soluble resin formed on the surface layer of the above-mentioned core component closely adhere to the outer layer 18.

[0060] The handle member 20 for a fishing rod according to an embodiment of the present invention thus formed can provide a handle member for a fishing rod having a spool seat with high workability of the inner surface, less likely to cause resin depletion, and no fiber burrs on the inner surface.

[0061] The dimensions, materials, and arrangements of the respective structural elements described in this specification are not limited to those explicitly described in the embodiments, and each of these structural elements can be deformed into any dimensions, materials, and arrangements that can be included within the scope of the present invention. Additionally, structural elements not explicitly described in this specification can be added to the described embodiments, or a part of the structural elements described in each embodiment can be omitted.
