Description

  The present invention relates to a fishing line guide formed of a resin material impregnated with reinforcing fibers and a fishing rod provided with the fishing line guide.

Among general fishing rods (hereinafter referred to as fishing rods), there is a fishing rod provided with a plurality of fishing line guides (hereinafter referred to as fishing line guides). The fishing line guide provided on these fishing rods is attached to either the upper surface or the lower surface of the rod depending on the type of reel used.
These fishing line guides are usually configured by fitting a guide ring made of SiC or the like into which a fishing line is inserted and supported in a frame made of a metal material having corrosion resistance such as titanium or stainless steel.

  With fishing rods, the strength of the fishing rod has been improved and the weight of the rod has been reduced as the diameter is reduced. When many fishing line guides having a metal frame are attached to a fishing rod that realizes this weight reduction, this is a factor that hinders the weight reduction of the rod.

  For a fishing line guide made of such a metal material, for example, Patent Document 1 discloses a frame with a prepreg, that is, a woven fabric base material made of reinforcing fibers such as a carbon material covering a plurality of layers coated with a thermosetting resin. There has been proposed a fishing line guide that is lightened by being formed. This fishing line guide is produced by stacking a plurality of prepregs and forming them by pressurization and heat treatment, and cutting or punching the fishing line guide.

JP 2011-004651 A

  For example, when the fishing line guide has a structure of a supporting leg part of a monopod (so-called single foot) connected to one fixed part as shown in FIG. 2A, the load due to the road line passing through the guide ring is The fishing line guide is concentrated on the bent part rising from the fixing part for fixing the fishing line guide to the fishing rod. Even when the fishing rod is carried, the impact on the bent portion is the strongest even when the tip end side of the guide ring is hit.

  For this reason, the prepreg is added and formed thick so as to be applied to the bent portion from the fixed portion to the support leg portion, thereby realizing the necessary strength. Further, a prepreg having the same thickness as or larger than the prepreg disposed inside is applied to both surfaces of the guide ring so that the joints and the like are not exposed.

  In the case of this structure, as shown in FIG. 8, when pressing and heat treatment with a mold are performed, the surface of the fiber sheet 10 a additionally disposed for reinforcement and the lower fiber sheet 10 b are caused to be covered by the step. In some cases, a small triangular gap m having a substantially triangular shape may occur between the fiber sheet 9a and the fiber sheet 9a. When the gap m exists, the strength is lower than that without the gap m, and the strength characteristics vary. Furthermore, even if the fishing line guide has a strength characteristic within the range of design performance (manufacturing standard), a product with a gap m sealed according to the user's appearance is a good product, and a product with a gap is a defective product. It can be judged. In addition, it is preferable that the gap m is closed in view of appearance.

  Therefore, the present invention includes a fishing line guide that fills a gap generated by the sheet end portion of a fishing line guide formed by a plurality of laminated fiber reinforced resin sheets, and that can provide a good appearance while preventing a decrease in strength, and the fishing line guide. The purpose is to provide fishing rods.

  In order to achieve the above object, a fishing line guide according to an embodiment of the present invention has an annular shape in which a plurality of reinforcing fibers are arranged and a plurality of fiber sheets impregnated with a heat-curing resin material are laminated to guide the fishing line. A frame main body integrally forming a fishing line guide portion, a supporting leg portion extending from an end portion of the fishing line guide portion, and a fixing portion bent and extended from a distal end side of the supporting leg portion, up to an end surface of the frame main body A gap sealing member for impregnating the reinforcing fiber arranged along the extending direction of the end portion with the resin material with respect to a short-width fiber sheet that does not reach and has an end portion in the laminate; A stop member is disposed in contact with the end portion of the short-width fiber sheet, and at the time of pressurizing and heating the frame body, an end surface of the end portion and a fiber sheet laminated so as to sandwich the end surface Change the cross-sectional shape Is allowed, characterized in that the embedding.

  According to the present invention, a fishing line guide that fills a gap generated by a sheet end portion in a fishing line guide formed by a plurality of laminated fiber reinforced resin sheets, prevents a decrease in strength, and obtains a good appearance, and the fishing line guide. A fishing rod can be provided.

  The fishing rod 1 of this embodiment is a type in which a double-axis reel (or bait reel) (not shown) is mounted on the reel seat 3 of the bat 2, and a plurality of fishing line guides 5 are provided on the upper surface of the rod body 4 at intervals. A top guide 6 is provided at the tip of the heel. In the following description, the tip side of the fishing rod is referred to as the front, and the heel side is referred to as the rear.

  The fishing line guide 5 includes a fiber reinforced resin sheet (hereinafter referred to as a fiber sheet) in which linearly extending reinforcing fibers are lined and impregnated with a resin material, a frame body 7 formed of a so-called prepreg, and an annular shape made of SiC or the like. It comprises a guide ring 8.

  The fiber sheet in this embodiment is a sheet member impregnated with a matrix resin in which a large number of linearly extending reinforcing fibers, for example, carbon fibers are knitted in the same direction or woven into a plain weave or the like and cured by thermal processing. Moreover, as a matrix resin, a thermosetting resin or a thermoplastic resin can be applied, for example, an epoxy resin, a polyamide resin, a phenol resin, an unsaturated polyester resin, etc. can be used. However, among the other members, members that do not dissolve at the curing temperature of the matrix resin are preferable. As the reinforcing fiber in the present embodiment, glass fiber, aramid fiber, metal fiber, synthetic resin fiber or the like can be used in addition to carbon fiber.

  The frame main body 7 is bent from the ring-shaped ring holding part (fishing line guide part) 7a provided on the upper side, the supporting leg part 7b that supports the ring holding part 7a, and the supporting leg part 7b, and is shown in FIG. A fixing portion 7c for attaching to the unit 4 is integrally formed. A guide ring 8 is fitted and fixed to the ring holding portion 7a. The ring holding part 7a has a ring shape such as a circle, an ellipse, an oval, or a track.

  The support leg portion 7b has a height (length) for separating the fishing line (road line) from the fishing rod by a predetermined distance. The supporting leg portion 7b has a V shape from two lower portions of the ring holding portion 7a, and is bent horizontally and connected to the fixing portion 7c. The V-shape of the support leg portion 7b is a shape generated by hollowing out the inside into a substantially triangular shape so that the strength is not easily affected in order to reduce the weight. Therefore, the supporting leg portion 7b does not necessarily have a V shape. The fixing portion 7c is placed at a predetermined position of the fishing rod, is wound and fixed, and is lapped and coated with resin or the like from the yarn surface.

  As shown in FIGS. 3 and 4, for example, the frame body 7 includes fiber sheets 10 b to 10 g laminated, and a short reinforcing fiber sheet 10 a covering from the lower surface of the sheet to the bent portion is addressed from the lower surface side. Furthermore, on the outermost surface, the fiber sheets 9a and 9b are overlapped so as to cover the upper and lower surfaces of the short-width fiber sheet 10a, the fiber sheet 10b, and the fiber sheet 10g, and are integrally configured. In addition, these fiber sheets 9a, 9b, 10b to 10g are basically the same member such as a fiber reinforced resin sheet. The number of fiber sheets described above is a number based on the strength required at the time of design, and is not particularly limited. Further, the gap m (FIG. 8) that exists between the above-described fiber sheet 9 a and the short-width fiber sheet 10 a is filled and embedded with a gap sealing member 11 made of the same material as the fiber sheet described later.

  FIG. 5 is a diagram conceptually showing a plurality of laminated fiber sheets and a gap sealing member before being press-formed. 6A and 6B are views for explaining the gap sealing member. Fig.7 (a) is a figure which shows notionally manufacture by the press molding of the frame main body 7, FIG.7 (b) is a figure which shows the external appearance structure of the fiber sheet formed integrally.

  In this configuration, as shown in FIG. 5, rectangular fiber sheets 10 b to 10 g serving as cores are stacked, and a short reinforcing fiber sheet 10 a covering from the fixing portion 7 c on the lower surface of the sheet to the bent portion is addressed. . Further, the gap sealing member 11 is disposed so as to be continuous with the upper end of the short-width fiber sheet 10a, and the fiber sheets 9a and 9b disposed on the upper and lower surfaces are overlapped with each other. As shown in FIG. 7 (a), these stacked fiber sheets 15 are set in the recesses of the mold 12, heated while being pressed by the mold 13, and the resin of each fiber sheet is dissolved. Are integrally formed so as to be in close contact with each other.

  Here, the gap sealing member 11 shown in FIGS. 6A and 6B will be described.

  A gap sealing member 11 shown in FIG. 6A is a member for sealing the gap m generated between the fiber sheet 9a, the fiber sheet 10a, and the fiber sheet 10b. The gap sealing member 11 has the same structure as that of the fiber sheet, and as shown in FIG. 6A, has a prismatic shape in which a large number of reinforcing fibers are arranged in the same linear direction n.

  The gap sealing member 11 is disposed at the upper end of the fiber sheet 10a shown in FIG. 5, and is pressed by the fiber sheet 9a, the fiber sheet 10a, and the fiber sheet 10b when being pressurized and heated for melting. Each reinforcing fiber moves in accordance with the shape of the substantially triangular gap m. That is, the pressure from the sheet surfaces 9a and 10b and the sheet end 10a generated by the pressurization of the mold acts in a direction perpendicular to the fiber arrangement direction of the gap sealing member 11, and is dissolved and fluidly sealed. The reinforcing fibers of the member 11 are moved together with the resin material. By changing the cross-sectional shape, the sheet surfaces are in close contact with each other without any gap or lift, and are solidified integrally to seal the gap m.

  The gap sealing member 11 shown in FIG. 7A has a prismatic shape, but may be a cylindrical gap sealing member 14 as shown in FIG. 7B. The shape is not particularly limited as long as the substantially triangular gap can be embedded. In addition, the gap sealing member 11 may be a thin fiber sheet wound or folded.

  Further, the loading and holding of the fiber sheet 15 in the mold 12 may be held by a mechanical part such as a metal claw, or may be held electrically such as electrostatic adsorption. A release agent may be applied so that the fiber sheet 15 can be easily removed after molding.

  Thereafter, as shown in FIG. 7B, the fiber sheet (prepreg molded product) 15 formed integrally from the cooled molds 12 and 13 is taken out. The frame body 7 is cut out from the bent plate-shaped fiber sheet 15. As a cutting method, for example, a laser beam, a water jet, or an apparatus using a blade, for example, a laser processing apparatus, a water jet processing apparatus, a resin NC processing apparatus, or the like can be used. Thus, the method of cutting out the frame main body 7 is a known method and is not particularly limited.

  Furthermore, when this cutting is performed, for example, the bottom surface of the fixing portion 7c may be curved so that the bottom surface of the fixing portion 7c is satisfactorily seated, and the fixing thread is easily hooked on the upper surface of the fixing portion. Groove processing may be performed.

  Further, the frame main body 7 may be subjected to chamfering processing, taper processing, and barrel polishing processing for preventing cracking from each edge and removing burrs. In addition, for surface protection, coating may be performed with a member having a thickness that does not increase weight and hardness (for example, ceramic, glass, or a metal having corrosion resistance (by salt water)). . For the film formation, a physical vapor deposition technique (PVD: evaporation method or sputtering method or the like) or a chemical vapor deposition technique (CVD: CVD method) can be used.

  Thereafter, the guide ring 8 is fitted into the ring holding portion 7a of the completed frame body 7 using a normal method, and is fixed with an adhesive or the like. In addition, depending on the load of the fishing rod used and the type of fishing line, the guide ring is not necessarily required. The inner surface of the ring holding part may be polished to a mirror surface, or a surface process for laminating a hard member may be performed separately. It may be processed so that the fishing line can be easily guided.

  As described above, according to the present embodiment, in order to strengthen the fixing portion 7c of the frame body 7, the gap generated by the end portion of the added fiber sheet is embedded by the gap sealing member made of the fiber sheet member. The gap can be sealed. Therefore, even if a reinforcing member having an end is added inside the stack of the frame main body, variation in strength characteristics due to the gap can be prevented. Furthermore, the finish on the side surface of the fishing line guide is improved, and the appearance is improved. In the present embodiment, the gap generated by the end portion of the fiber sheet used for reinforcing the fixing portion 7c is taken as an example. It may be an application example for sealing the gap.

Further, in the present embodiment, the fishing line guide having one support leg has been described as an example. However, the present invention is not particularly limited, and any one can be used as long as the gap is generated by the end of the fiber sheet added by reinforcement or the like. The present invention can also be applied to such places, and even a fishing line guide having two or more support legs can be easily implemented in the same manner.
When such a fishing line guide is employed in a fishing rod that has been reduced in weight, the weight of the fishing rod as a whole can be reduced without hindering the weight reduction of the fishing rod.
