JP 2006-340661 A Japanese Patent Application No. 2009-83178

  In the fishing line guide disclosed in Patent Document 1 described above, since the frame is formed of a metal material, the weight increases and the flexibility is poor, which is a bottleneck in improving the performance of the fishing rod. For example, in a fishing rod that is required to be lighter, if a large number of fishing line guides as described above are attached along the axial length direction, desired performance cannot be exhibited. Therefore, according to the fishing line guide proposed in Patent Document 2 described above, since the frame of the fishing line guide is formed of fiber reinforced resin (for example, FRP or FRTP), it is possible to solve such a problem. .

  By the way, in the fishing line guide proposed in Example 1 of Patent Document 2, since the frame of the fishing line guide is formed from a plate-like body, the surface becomes flat and there is room for further improvement in terms of appearance. There is. In other words, like the frame disclosed in Patent Document 1, although it is bent, it is a flat part when considering the extending direction of each surface, and the frame is cut out and formed. Since the edge portion of the frame is cut out in a direction perpendicular to the planar portion, the directionality on the frame surface is poor, and there is room for improvement in view of the appearance shape.

The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a fishing line guide made of a fiber reinforced resin that can be reduced in weight and improved in strength and has a good appearance.

  In order to achieve the above object, the present invention is a method of manufacturing a fishing line guide having a frame comprising a ring holding part and a fixing part attached to a fishing rod, and comprising a fiber reinforced prepreg, A primary processing for forming the outer shape of the frame from a laminated material in which fiber reinforced prepregs are laminated, and a secondary processing for heating the laminated material to change the shape of the frame to a predetermined shape. The frame is cut out from the laminated material before or after the secondary processing.

  According to the method for manufacturing a fishing line guide having the above-described configuration, in the primary processing, the outer shape of the frame is specified, and then the laminated material is further heated and subjected to the secondary processing to thereby obtain a partial shape of the frame. In addition, it is possible to adjust the shape of the details with high accuracy, and this makes it possible to reduce the weight and improve the strength and to obtain a fishing line guide with improved texture. Note that the frame is cut out from the laminated material at the time of the primary processing, and the secondary processing may be performed on the cut frame, or the secondary processing is performed subsequent to the primary processing. Thereafter, a frame cut-out process may be performed. The fiber reinforced prepreg may be one in which a reinforcing fiber is impregnated with a thermoplastic resin, or one in which a reinforcing fiber is impregnated with a thermosetting resin.

  In order to achieve the above object, the present invention includes a ring holding part and a fixing part attached to a fishing rod, and a frame cut out from a laminated material of fiber reinforced prepreg formed in a plate-like body. The frame has a planar portion that becomes the surface of the plate-like body, and has a processing surface at any part, and the extending direction of the surface of the processing surface Crosses the extending direction including the planar portion.

  In the fishing line guide having the above-described configuration, since the frame portion of the fishing line guide is constituted by the fiber reinforced prepreg, a lightweight and high strength fishing line guide can be obtained. In addition, for example, in the frame, in addition to the planar portion formed when the plate-like body is cut out, a processing surface that is in a direction intersecting the extending direction including the planar portion at a desired position Therefore, the fishing line guide is improved in the appearance of the entire frame.

  Hereinafter, embodiments of a fishing line guide and a manufacturing method thereof according to the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing an example of a fishing rod to which a fishing line guide according to the present invention is attached. The fishing rod 1 is formed by joining a plurality of rods 2, and a reel seat 5 on which a fishing reel (not shown) is mounted is provided on the base end side, and each rod has a predetermined interval. The fishing line guide 10 for guiding the fishing line fed out from the fishing reel is mounted. In this case, the fishing line guide 10 is mounted by placing a fishing line fixing portion, which will be described later, on the surface of the rod and winding the thread or bonding it. In addition, about a fishing line guide, it may be comprised as what is called a fixed guide fixed with respect to a rod, and may be comprised as an idle guide which can slide along a rod. Further, the fishing rod is not particularly limited in its configuration, such as a single rod, a row rod, a swing rod, and the fishing line guide of the present embodiment is an introduction guide portion of a mid-type fishing rod. It is also possible to apply to the top guide part.

  Next, the configuration of the fishing line guide attached to the fishing rod shown in FIG. 1 will be described with reference to FIGS. 2 is a perspective view showing the first embodiment of the fishing line guide, FIG. 3 is a front view of the fishing line guide shown in FIG. 2, and FIG. 4 is a longitudinal section of the fishing line guide shown in FIG. 5 is a cross-sectional view taken along line AA in FIG. 3, FIG. 6 is a cross-sectional view taken along line BB in FIG. 3, and FIG. 7 is taken along line CC in FIG. 8 (a) and 8 (b) are cross-sectional views showing modifications of the supporting leg portion shown in FIG. 6, and FIG. 9 is an enlarged cross-sectional view of a portion where the guide ring is mounted in the ring holding portion. FIG. In FIG. 4, the D1 direction is the front side (the tip side), and the D2 direction is the rear side (the front end side).

  The fishing line guide 10 includes a frame 12 formed of a fiber reinforced prepreg (hereinafter referred to as a prepreg) in which a reinforcing fiber is impregnated with a synthetic resin (the prepreg configuration and a detailed manufacturing method of the frame will be described later). . The frame 12 is fixed to the fixing portion 15 attached to the outer surface of the fishing rod (竿 2) shown in FIG. 1, the ring holding portion 17 to which the guide ring 40 through which the fishing line is inserted is attached, and the ring holding portion 17. And a support leg portion 18 connecting the portion 15. The synthetic resin constituting the prepreg may be thermoplastic (FRTP) or thermosetting (FRP) as described later.

  The fixing portion 15 is a portion (also referred to as a foot portion) that is fixed to the surface of the fishing rod at the lower end of the frame. In the present embodiment, the fixing portion 15 extends in the axial direction, and the contact surface 15a on the back side of the fishing rod is It is formed of a plate-like piece that is fixed by thread fastening, adhesion, or the like while placed on the surface.

  The ring holding part 17 is a part for fastening the guide ring 40 so as to guide the fishing line in a state of being separated from the surface of the fishing rod. The ring holding portion 17 is formed with an opening 17a for fitting and fixing the guide ring 40, and has a substantially circular outer shape as a whole. In this case, the guide ring 40 inserted into the opening 17a is configured in a ring shape and has a small sliding resistance at the fishing line guide surface 40a, which is the inner peripheral surface thereof, such as titanium, aluminum, SUS, ceramics, etc. Is formed by. The guide ring 40 is fitted and fixed to the opening 17a of the ring holding portion 17 after the frame 12 is integrally formed by the prepreg. The “ring holding portion” includes a configuration in which the fishing line is directly guided through the opening 17a without mounting the guide ring, in addition to the above-described guide ring 40 being mounted to guide the fishing line.

  The support leg portion 18 is a portion that connects the fixing portion 15 and the ring holding portion 17 so that the ring holding portion 17 (guide ring 40) is separated from the surface of the fishing rod. In this case, depending on the configuration of the fishing line guide, the fixing portion 15 may be formed as it is in the ring holding portion without forming the support leg portion. Further, the support leg portion 18 of the present embodiment gradually becomes wider as it moves upward, and is integrally connected to the substantially circular ring holding portion 17 described above. In this case, as shown in the figure, the support leg 18 may be formed with an opening (thickening) 18a in order to reduce the weight.

  The frame 12 of this embodiment is formed by cutting out a plate-like body as will be described later. The frame 12 may be formed in a simple flat plate shape so that it can be applied to the floating guide, or it can be bent by forming a support leg portion between the fixed portion 15 and the ring holding portion 17 as shown in the figure. It is good also as a structure which has a part. If the bent portion is formed in the frame, as will be described later, the bent portion may be formed by bending the corresponding region in advance with respect to the flat plate-like body. A first bent portion 19 is formed at a boundary portion between the fixed portion 15 and the support leg portion 18, and a second bent portion that is bent more gently than the first bent portion on the ring holding portion 17 side of the support leg portion 18. 20 is formed.

  When the above-described bent portion is formed on the frame 12, in particular, by forming the second bent portion 20 on the support leg portion 18, the bending angle by bending the entire frame is set stepwise. It is possible to improve the strength by dispersing the stress concentration.

  As will be described later, the frame 12 is formed by cutting out from a prepreg laminated material formed on a plate-like body, so that the frame has a planar portion that becomes the surface of the plate-like body. . The planar portion means a portion having a planar shape excluding a processing surface formed by secondary processing described later, and is a portion formed by the surface of a plate-like body in the present embodiment. For this reason, even if the plate-like body is bent to form the fixing portion 15, the ring holding portion 17, and the support leg portion 18 between them, the surface of each part remains as it is. The portion becomes a “planar portion”.

  In the present invention, after performing the primary processing for forming the outer shape of the frame on the prepreg, further, the secondary processing processing (processing processing to change the shape by heating) is performed on the desired planar portion, A feature is that a processing surface that intersects the extending direction of the planar portion is formed. That is, by performing such secondary processing, for example, the planar portion is inclined at a predetermined angle, or the planar portion extending in the length direction is formed in a mountain shape or an arc shape in cross section. Or a concave portion or a convex portion is partially formed with a flat portion left. The processing surface formed by such secondary processing processing is a curved surface (planar shape, curved with respect to a planar portion, such as forming a taper in a proper position, forming a stop, or forming a chamfer. In this way, it is possible to obtain a three-dimensional appearance rather than a flat appearance when viewed as a whole frame.

  Here, the processing surface formed by the secondary processing in the frame 12 of the present embodiment will be specifically described.

  FIG. 5 is a cross-sectional view taken along the line AA of FIG. As described above, the ring holding portion 17 is formed with the opening 17a for fixing the guide ring 40. In FIG. 5, the plane including the axis X is a planar portion. That is, the surface part on the tip side and the heel side of the ring holding part 17 is a planar part formed by the primary processing, and the opening 17a is formed by the cutting process. In this case, the drawing processing surface may be formed by secondary processing on the inner surface portion where the guide ring 40 is mounted (see FIG. 9).

  6 is a cross-sectional view taken along line BB in FIG. As described above, since the opening 18a is formed in the support leg portion 18, the support leg portion 18 includes the left leg 18b and the right leg 18c. In this case, the shapes of the left leg and the right leg are formed so that the inner opening side projects forward (tip side) D1. That is, in FIG. 6, the plane including the axis X is a flat portion, but the left leg 18 b and the right leg 18 c protrude forward with an inclination angle θ with respect to such a flat portion. Secondary processing is performed so as to have such a flat inclined surface.

  FIG. 7 is a cross-sectional view taken along line CC in FIG. As described above, although the opening 18a is formed in the support leg portion 18, the lower side thereof is a portion where the left leg 18b and the right leg 18c are integrated. The part to be integrated is formed in a V-shaped cross section so that the center side protrudes forward D1. That is, in FIG. 7 as well, the surface including the axis X becomes a planar portion, but such a planar portion is subjected to secondary processing so as to have planar composite surfaces 18d and 18e.

  In addition, the above-mentioned processing surface shows an example and can be variously modified. For example, with respect to the left legs 18b and 18c, as shown in FIG. 8 (a), the center of the radius of curvature exists on the axis X and curved, or as shown in FIG. It can be appropriately modified, for example, bent into a letter shape. In this case, if the curve is tightened or the V-shaped bending angle is excessively increased, the strength of the reinforcing fiber may meander after the secondary processing, and the strength may decrease. It is preferable not to bend or greatly bend. Specifically, in the case of a curved surface, it is preferable to form the reinforcing fiber so that the reinforcing fiber bends and changes its direction at a radius of 5 times or more, preferably 10 times or more the diameter of the reinforcing fiber. In addition, if a bent surface is used, the secondary processing is performed in a range where the angle of bending is 90 ° or less (preferably, the angle α shown in FIG. 8B is 60 ° or less (but 5 ° or more)). It is preferable. Furthermore, if a bent part is to be formed, it is preferable to form a flat surface (a flat surface in a state in which the flat surface before the secondary processing and the fiber direction and the laminated state are maintained) on the side.

  Further, the surface layer is in the same laminated state as in the primary processing even after the secondary processing described above, and has, for example, a plain weave, satin fold, and triaxial weave appearance. Specifically, as shown in FIG. 9, as described above, the surface portions on the tip side and the heel side of the ring holding portion 17 are formed with a planar portion by the primary processing process, and the opening 17a is formed by the cutting process. However, the inner surface portion to which the guide ring 40 is attached may be formed with a processing surface 17d that is bent along the fishing line insertion direction from the planar portion by secondary processing. In this case, it is preferable to perform the secondary processing so that the stacked state of the ring holding portion 17 and the stacked state on the processing surface 17d are the same.

  Further, portions where the reinforcing fibers change at a steep angle, such as a bent portion (a position indicated by reference sign P in FIGS. 2 and 3), are not easily formed along the length direction because damage is likely to occur. preferable. If it must be formed, the thickness or cross-sectional area of the part is 1.3 times or more, preferably 1.5 times or more than the part before and after the reinforcing layer, for example. It is better to make it larger (however, it is not necessary to make it more than 3 times).

  Next, a method for forming the frame 12 having the above configuration will be described. First, the overall steps of the primary processing will be described with reference to FIGS. 10 to 13, and then the steps of the secondary processing, and the prepreg lamination state and the reinforcing fiber arrangement state will be described.

  As described above, the frame 12 is formed by a prepreg in which a reinforcing fiber is impregnated with a synthetic resin. In this case, the prepreg is configured in a state in which reinforcing fibers such as carbon fiber, glass fiber, and aramid fiber are aligned in a predetermined direction or in a knitted sheet shape, and a thermoplastic resin (for example, nylon) , Polypropylene, polyphenyl sulfide, thermoplastic polyurethane) or thermosetting resin (for example, epoxy resin, phenol resin, polyester resin) is impregnated as a matrix resin. The matrix resin may be in an uncured state, a semi-cured state, or a cured state at normal temperature. In addition, when performing a secondary processing process, the process process differs in the case of a thermoplastic resin and the case of a thermosetting resin.

First, a laminated material using a prepreg of a thermoplastic resin will be described.
First, the prepreg as described above is cut into a predetermined shape, and is laminated so as to form a plurality of layers to form a laminated material. FIG. 10 shows a plate-like laminate 30 in which seven prepregs are laminated (fiber reinforced resin layers formed by laminating prepregs are indicated by reference numerals 30a to 30d, respectively; the same prepreg Are given the same reference numerals). In this case, the number of prepregs to be overlapped (number of layers) and the configuration of individual prepregs are not particularly limited. However, as described above, the bent portions 19 and 20 are formed on the frame 12, and in use. In consideration of the load applied to the frame 12, the characteristics of the fishing rod to be mounted, the mounting portion, and the shape of the processing surface formed by the secondary processing, etc. Is done.

  The laminated material 30 may have a plate shape (in addition to a simple flat plate shape, for example, a T shape, a Y shape, or an H shape) or a tubular shape (a hollow cylindrical shape or an oval shape). It is possible to make any shape depending on the desired shape of the frame after cutting out, such as a shape.

  A primary processing is performed with respect to the prepreg laminated | stacked as mentioned above. In this primary processing, first, a mold 50 as shown in FIG. 12 is set. The mold 50 according to the present embodiment includes an upper mold 51 and a lower mold 52 that are divided vertically, and the laminated prepreg (laminated material 30) is set at a predetermined position of the lower mold 52. Between the upper mold | type 51 and the lower mold | type 52, the cavity 50a is formed according to the position where the laminated material 30 is set, and the mold release agent is coated in the surface area.

  The upper die 51 constituting the mold 50 is concave, and the lower die 52 is convex, and the frame having the fixing portion 15, the ring holding portion 17 and the support leg portion 18 when both are pressed. The hollow portion 50a (which corresponds to the thickness of the frame 12) is formed between the two so that 12 is formed. Then, when the laminated material 30 is placed on the lower mold 52, the bent forming convex parts 52 a and 52 b are formed at positions corresponding to the bent parts 19 and 20 described above, and the upper mold 51 is bent and formed. Bending formation concave portions 51a and 51b are formed corresponding to the convex portions 52a and 52b.

  The laminated material 30 may be set in the lower mold in a state where the whole is overlapped at a time, or may be laminated in a plurality of times, for example, one by one. By dividing into a plurality of times as described above, the movement of the reinforcing fibers can be reduced, and the lower mold 52 can be accurately set at a predetermined position. In the present embodiment, since the mold 50 is divided vertically as described above, the laminated material 30 is placed on the lower mold 52 and held in a predetermined shape according to the shape of the mold. Of course, the mold is merely an example, and the mold dividing direction can be in any form such as a horizontal direction or an inclined direction.

  And after setting the laminated material 30 to the lower mold | type 52, the mounting material 30 is pressurized and fixed. At the time of this pressurization and fixation, the matrix resin is heated to the plastic temperature (depending on the material, 140 ° C. to 600 ° C.). About pressurization and fixation, it may be tightened with the upper mold 51, or may be pressed with a hand or a pressing tool. At this stage, the shape corresponding to the frame shape after molding, including the bent portion, is maintained.

  In addition, when pressing the above-mentioned bending part with the metal mold | die 50 and heating, it is preferable that the bending part presses relatively stronger than the area | region before and behind that. Thus, by strongly pressing the area of the bent portion, voids in the bent portions (19, 20) of the molded frame can be prevented, and the strength can be improved and stabilized. As a result, the bent portions 19 and 20 of the molded frame 12 can have a higher fiber ratio than the front and rear regions (fixed portions and supporting leg portions), thereby strengthening the bent portions that are easily damaged. It becomes possible to do.

  FIG. 11 shows a state in which a flat plate-like body (laminated material 30) in which prepregs are laminated is pressed and heated by the primary processing described above and then cured at room temperature (the outer shape of the frame 12 is configured). A plate-like body 30A) is shown. In this case, a plurality of the frame 12 are cut out from the formed plate-like body 30A, but this cutting process may be performed at a stage before the following secondary processing process, It may be performed at the stage where the secondary processing is completed.

Here, a process of cutting out individual frames from the formed plate-like body 30A will be described.
As described above, when the laminated material 30 is heat-treated with a mold and then taken out, it becomes a plate-like body 30A in which the bent portions 19 and 20 are formed. By adopting an arbitrary method such as cutting by pressing, cutting by liquid (water jet, etc.), cutting by a blade (end mill, etc.), etc., as shown in FIG. The plurality of frames 12 can be cut out from the plate-like body 30A, and a lightweight and high-strength fishing line guide can be efficiently manufactured.

  In this cutting process, it is preferable to simultaneously form the basic outer shape of the frame 12, that is, the ring holding portion 17 having the opening 17a, the support leg portion 18 having the opening 18a, and the like. May be formed. In addition, regarding the laminated material 30 for forming the plate-like body 30A, not only a simple planar shape but also a shape in which the laminated thickness is changed depending on the position or the plate-like portion extends in a plurality of directions (T Or a curved surface shape, or a plurality of plate-like portions may be combined.

  As described above, the secondary processing is performed on the cut out individual frames 12 or the plate-like body 30A before the cutting processing is performed in order to form the processing surface described above. Hereinafter, with reference to FIGS. 14 to 16, a process of forming the processing surface shown in FIGS. 6 and 7 will be described. Although secondary processing may be performed on the plate-like body 30A, in the following, the primary processing is finished and the secondary processing is performed on one frame 12 cut out from the plate-like body 30A. It will be described as being performed.

  In the secondary processing, the frame 12 (plate-like body 30A) is set in a mold 60 as shown in FIG. Similar to the above-described mold 50, the mold 60 is composed of an upper mold 61 and a lower mold 62 that are divided vertically, and irregularities are formed so that a processing surface is formed at a predetermined position. Has been. Specifically, a cavity 60 a in which the frame 12 is set is formed between the upper mold 61 and the lower mold 62. Further, the lower mold 62 is formed with a convex portion 62a in accordance with the opening of the support leg portion 18, and the left and right legs 18b and 18c are inclined on both sides of the convex portion 62a as shown in FIG. The inclined surfaces 62b and 62c are formed (see FIG. 15). Moreover, the lower mold | type 62 is formed with the mountain-shaped convex part 62d for forming the support leg part 18 in V shape as shown in FIG. 7 (refer FIG. 16). Then, in accordance with these convex portions 62a and 62d, concave portions 61a and 61d are also formed in the upper mold 61, respectively.

  Thereby, the cut frame 12 is set at a predetermined position of the lower mold 62, and then heated until the resin is in a plastic state, and when the resin is in a bendable state, pressure is applied to the mold, The processing surface is formed by maintaining the pressure state. And after that, the processing surface of the stable state is formed by cooling to normal temperature. The surface area of the upper mold 61 and the lower mold 62 is coated with a release agent.

  After the secondary processing described above is finished, a detailed processing is performed. This detailed processing is performed on the frame 12 after the secondary processing, but if the frame is not cut out, the plate-like body 30A at the time when the secondary processing is completed, or The frame 12 that has been cut out from the plate-like body 30A is applied. For example, the end portion of the fixed portion is formed so that the corner portion is rounded, the shape of the fixed portion 15 is formed in a curved shape so that it can be easily placed on a fishing rod, or the thread is wound and fastened easily. This applies to grinding and polishing.

  Next, a surface treatment is performed on each frame 12. For example, by performing barrel processing, surface burrs are removed, and finish polishing is performed to such an extent that surface gloss is obtained. Regarding the degree of this polishing, it is possible to arbitrarily adjust the polishing agent, polishing time, etc. depending on the size, shape, material characteristics, etc. of the fishing line guide. By performing such barrel processing, the frame can be polished without cutting the reinforcing fibers, the strength can be stabilized, and a fishing line guide having an excellent appearance can be obtained.

  In addition, when performing such a polishing process, it is preferable to polish so that a part of the reinforcing fibers are exposed on the surface of the frame and a part of the matrix resin remains. By doing so, it becomes possible to further improve the gloss of the polished surface.

  Next, a film is formed on the whole or a part of the frame as necessary. For example, it is possible to perform coating to improve the appearance and protect the frame body, or to deposit metal or ceramics.

  Then, the guide ring 40 is attached to the opening 17a portion of the frame formed as described above. As a method for attaching the guide ring, press-fitting, adhesion, curling, or any other fixing method can be employed.

Next, the case where it is a laminated material by the prepreg using a thermosetting resin is demonstrated.
First, as in the case of the above-described thermoplastic resin, the prepreg is cut into a predetermined shape, and the laminated material 30 is formed by overlapping the prepreg so as to form a plurality of layers, and the primary processing is performed.

  In the primary processing, as in the case of the thermoplastic resin, the laminated material 30 is set in a mold 50 as shown in FIG. 12, and the laminated material 30 is pressurized and fixed. About this pressurization and fixation, you may clamp | tighten with the upper mold | type 51, and may press with a hand or a pressing tool. At this time, heat treatment is performed at a temperature lower than the temperature at which the prepreg is cured, and processing is performed so that the laminated material 30 is in a semi-cured state (temporary cure). At this stage, the shape corresponding to the shape of the frame after molding, including the bent portion, is maintained, whereby a semi-cured plate-like body 30A is obtained (see FIG. 11). Here, the semi-cured state of the laminated material 30 means a state in which it can be machine-molded, such as being uncured and capable of shape deformation.

  Next, the secondary processing is performed on the semi-cured plate-like body 30A. When this secondary processing is performed, the frame 12 may be cut out from the semi-cured plate-like body 30A in the previous stage, or the cutting process may be performed thereafter.

  In the secondary processing, the frame 12 (plate-like body 30A) is set in a mold as shown in FIGS. That is, the frame 12 (plate-shaped body 30A) is set at a predetermined position of the lower mold, and then the pressure is applied to the mold, and the pressure state is maintained and the semi-cured frame 12 (plate-shaped body 30A). ) Is cured to form a processed surface.

  The frame 12 (plate-like body 30A) on which the processed surface is formed is then subjected to detailed processing and surface treatment as in the case of the thermoplastic resin described above, thereby obtaining a frame with improved appearance. Thus, if the matrix resin of the prepreg is thermosetting, in the primary processing, the outer shape of the frame is formed in a semi-cured state (uncured state) at a temperature lower than the curing temperature. In this state, the final frame form is obtained while performing heat treatment at a temperature higher than the curing temperature so that a further desired processing surface is formed.

  And in the secondary processing for the laminated material by the prepreg using the above-mentioned thermoplastic resin or thermosetting resin, depending on the material of the matrix resin, the deformation amount for forming the processing surface, the arrangement of the reinforcing fibers, etc. The pressurizing force, pressurizing time, heating temperature, and the like are adjusted, and these relate to the laminated structure of the fiber reinforced prepreg of the frame 12 formed into a predetermined shape after the secondary processing is finished, and the reinforcement in the planar portion It is preferable to adjust so that the direction of the fibers and the arrangement of the laminated layers are the same as the arrangement of the laminated layers and the direction of the reinforcing fibers in the laminated material during the primary processing. That is, it is preferable to perform the secondary processing after fixing the arrangement and direction of the reinforcing fibers after the primary processing. Here, the same means that even if the original shape is changed by the secondary processing, the direction of the reinforcing fibers and the arrangement state of the layers maintain the same arrangement state relative to the surface portion. Means.

  By doing in this way, the direction and lamination | stacking arrangement | positioning of the reinforcement fiber of the planar part which shape changes by secondary processing can be stabilized, and an intensity | strength improvement and stabilization can be aimed at now. In addition, the shape of the frame can be made arbitrary, and by maintaining the fiber direction, etc., in the same state as before processing, the appearance of the part where the lamination or fiber direction has been subjected to secondary processing and the part not added is maintained in the same state. This makes it possible to prevent the appearance of discomfort and achieve an excellent appearance.

  Next, when the frame 12 is formed by the prepreg as described above, a preferable arrangement mode of the prepreg will be described.

  As shown in FIG. 10, the laminated material 30 of the present embodiment includes an axial length direction fiber resin layer 30a in which reinforcing fibers are aligned along the axial length direction of the fishing rod, and a predetermined length with respect to the axial length direction of the fishing rod. It has diagonal fiber resin layers 30b and 30c in which reinforcing fibers are aligned in an intersecting direction having an angle, and a woven fabric layer 30d in which reinforcing fibers are knitted.

  Specifically, in this embodiment, the axial length is increased by a prepreg in which reinforcing fibers are aligned in the axial length direction in a neutral axis area (in FIG. 10, the neutral axis is indicated by X1) that is an intermediate position of the frame thickness. The directional fiber resin layer 30a is disposed, and on the outside (both sides) at a predetermined angle with respect to the axial length direction (the inclination angle is arbitrary, but is preferably 15 to 75 degrees, more preferably 30 to 60 degrees). The oblique fiber resin layers 30b and 30c are arranged by the prepregs in which the reinforcing fibers are aligned, and the reinforcing fibers are knitted in the outermost layer (the entire surface on both sides may be partially outermost). The woven fabric layer 30d is disposed by the prepreg. The axial length direction fiber resin layer 30a may have a plurality of layers (1 to 4 layers). The oblique fiber resin layers 30b and 30c may have different orientation directions of the reinforcing fibers in the respective layers.

  Thus, when forming a fishing line guide made of fiber reinforced resin, it is preferable to select and laminate prepregs in which the reinforcing fibers are oriented in at least three directions when the frame itself is viewed in plan. That is, by setting the direction of the reinforcing fibers to three or more directions, it is possible to form a fishing line guide that is efficient, lightweight, and excellent in strength.

  Moreover, it is preferable to arrange | position the woven fabric layer 30d in the outermost layer of the flame | frame 12 like the arrangement | positioning structure of an above described prepreg. This is because the surface of the frame 12 is a part that is easily hit by other objects and is easily peeled off, and the reinforcing fibers are peeled off from the end of the frame such as when the frame is bent by the tension of the fishing line during actual fishing. Since there is a possibility of breakage, by arranging a woven fabric layer in which reinforcing fibers are knitted in this surface region, it is possible to effectively prevent tearing and peeling of the reinforcing fibers, improving strength, And stabilization can be achieved. In addition, the bent portions 19 and 20 can be relatively strengthened, and a fishing line guide that is lightweight and excellent in strength balance can be obtained.

  Moreover, it is preferable to arrange | position the axial direction direction fiber resin layer 30a in the intermediate | middle layer area | region of the flame | frame 12 like the above-mentioned structure. As a result, even if a bending force is applied to the frame 12 by the tension of the fishing line along the axial length direction, it is possible to efficiently increase the specific rigidity in that direction while reducing the weight.

  Moreover, it is preferable that the fiber ratios of the bent portions 19 and 20 are set higher than those before and after the bent portions 19 and 20. For example, as explained in the above-mentioned primary processing step, by increasing the pressing force in the region of the bent portion at the time of thermoforming, the resin can flow out and the fiber ratio of the bent portion can be increased. With such a configuration, it is possible to provide a fishing line guide that is not easily damaged even when the frame is bent due to an applied load.

  According to the fishing line guide formed by the manufacturing method as described above, the weight is lighter than that made of metal, and further, the structure is excellent in specific strength, specific rigidity, and flexibility. It becomes possible. For this reason, even if a large number of such fishing line guides are mounted, the entire fishing rod is not increased in weight, and the performance of the fishing rod is improved. In particular, a portion such as a tip rod can be further reduced in weight, so that it is easy to sense delicate hits, and the performance of the fishing rod can be further improved.

  Further, the frame 12 (or the plate-like body 30A) after the fiber-reinforced prepreg is laminated and cut out is subjected to heat processing (secondary processing) again, so that the partial shape and angle of the frame can be reduced. Adjustment and the like can be formed with high accuracy. In addition, it is possible to prevent the movement of the reinforcing fibers and the flow of the synthetic resin by adjusting the shape after fixing the arrangement and direction of the reinforcing fibers by laminating and improving the strength. As a result, stabilization can be achieved and a frame having a complicated shape can be formed.

  For example, like the frame 12A of the fishing line guide 10A shown in FIG. 17, the support legs 18A are formed from the ring holding part 17A toward the tip side and the heel side, and project in the front-rear direction at the ends of the support legs. It is also possible to adopt a structure having the fixing portion 15A. Alternatively, like the frame 12B of the fishing line guide 10B shown in FIG. 18, the support leg 18B is formed from the ring holding part 17B toward the tip, and the fixing part 15B protruding forward is formed at the end thereof. It is also possible to adopt a structure having a pair of supporting leg portions 18C inclined from the upper end portion of the ring holding portion 17B toward the main shaft side. In this case, the pair of support leg portions 18C can be processed into a processed surface as shown in FIGS. 6 and 8, and thereby a fishing line guide having an excellent appearance can be obtained. The fishing line guide shown in FIG. 18 can also be applied to the fishing line introduction guide portion of the Nakatsu fishing rod.
