Hereinafter, an embodiment of a fishing line guide according to the present invention will be described with reference to the drawings.
First, a configuration example of a fishing line guide according to the present invention will be described with reference to FIGS. In these drawings, FIG. 1 is a longitudinal sectional view of a fishing line guide, FIG. 2 is a view of FIG. 1 as viewed from the direction of arrow A, and FIG. 3 is a view showing that the fishing line guide is mounted on a fishing rod (a rod). It is a figure which shows a state. In FIG. 1, the direction of arrow A coincides with the axial direction of the fishing rod when the fishing line guide is attached to the fishing rod, and FIG. 3 is a view of the tip rod side from the main rod side. Yes.

  The fishing line guide 1 includes a frame 3 formed of a fiber reinforced prepreg (hereinafter referred to as a prepreg) in which a reinforced fiber is impregnated with a synthetic resin (the prepreg configuration and a detailed manufacturing method of the frame will be described later). . The frame 3 includes a fixing portion 5 attached to the outer surface of a fishing rod (rod tube) 40, a ring holding portion 7 to which a guide ring 6 through which a fishing line is inserted is attached, and the ring holding portion 7 and the fixing portion 5. And a support leg portion 8 for connecting the two.

  The fixing portion 5 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 5 extends in the axial direction, and the contact surface 5a on the back side of the fishing rod is In a state where it is placed on the surface, it is fixed by thread fastening, adhesion or the like. In addition, the fixing | fixed part 5 can take various shapes, such as one leg and two legs.

  The ring holding part 7 is a part for fastening the guide ring 6 so as to guide the fishing line in a state of being separated from the surface of the fishing rod. The ring holding part 7 is formed with an opening 7a for fitting and fixing the guide ring 6 and has a substantially circular outer shape as a whole. The guide ring 6 inserted into the opening 7a is formed in a ring shape, and is made of a member having a small sliding resistance at the fishing line guide surface 6a, which is the inner peripheral surface thereof, such as titanium, aluminum, SUS, ceramics, or the like. Is formed. The guide ring 6 is fitted and fixed to the opening 7 a of the ring holding portion 7 after the frame 3 is integrally formed by the prepreg.

  The support leg 8 is a part for connecting the fixing part 5 and the ring holding part 7 so that the guide ring 6 is separated from the surface of the fishing rod.

  The frame 3 is formed with at least one bent portion. In the present embodiment, the first bent portion 10 a is formed at the boundary portion between the fixed portion 5 and the support leg portion 8, and more gently on the ring holding portion 7 side of the support leg portion 8 than the first bent portion. A second bent portion 10b is formed. In this case, the boundary portion corresponds to a region that rises toward the ring holding portion 7 from the end portion of the fixing portion 5 that is actually fixed to the outer surface of the fishing rod.

  When forming the bent portion as described above in the frame 3, in particular, by forming the second bent portion 10 b in the support leg portion 8, the bending angle by bending the entire frame can be set stepwise. Thus, the strength can be improved by dispersing the stress concentration. Further, if a plurality of bent portions 10a and 10b are formed in the frame 3 as described above, a bent portion (in the drawing, in the boundary portion between the fixed portion 5 and the support leg portion 8 or in the vicinity thereof) It is preferable to set the bending angle of the bent portion (corresponding to the second bent portion 10b in the drawing) formed on the support leg portion 8 smaller than that of the first bent portion 10a. Specifically, the bending angle θ1 of the bending portion formed at or near the boundary portion between the fixed portion 5 and the supporting leg portion 8 is in the range of 30 to 90 degrees, and the bending portion formed on the supporting leg portion 8 is. The bending angle θ2 of the part is preferably in the range of 0 to 45 degrees with an angle smaller than that (θ1> θ2), and preferably 30 degrees or more and 100 degrees or less when both angles are combined.

  As shown in FIG. 1, the bending angle is defined by an angle at which tangent lines intersect before and after the bent portion. As described above, when the two bent portions 10a and 10b are formed on the frame, the relationship between the angles is preferably set as described above. Further, the bending angle between the fixing portion 5 and the ring holding portion 7 (the angle at which the lower surface tangent of the fixing portion 5 and the ring holding portion 7 intersect) θ3 may be set in the range of 30 to 100 degrees. preferable. Further, the above-described support leg portion 8 is formed in a straight line between the two bent portions 10a and 10b, but may be formed in a curved shape having a predetermined curved surface between the two bent portions 10a and 10b. Alternatively, the entire support leg portion may be formed of a curved surface.

  By forming the bent portion so as to have such an angular relationship, stress concentration on the specific bent portion can be prevented, and the strength can be stabilized.

  The bent portions 10a and 10b formed on the frame as described above are regions that are easily damaged due to stress concentration. However, by using a manufacturing method and a prepreg configuration as described later, Strength and specific rigidity are improved.

  Further, as will be described later, the frame 3 is formed by pressing or the like from a prepreg (a plate-like body after heat forming) in a state in which a bent portion having the above-described configuration is formed in advance. At this time, it is formed to have a predetermined outer shape. In the present embodiment, as shown in FIG. 2, the frame 3 has a support leg portion 8 that rises from the end of the fixed portion 5 via the first bent portion 10a, and gradually becomes wider as it moves upward. The ring 6 is integrally connected to a substantially circular ring holding portion 7 in which an opening 7a is formed. In this case, as shown in the figure, the support leg portion 8 may be formed with an opening (thickening) 8a in order to reduce the weight.

  Next, a method of forming the frame 3 having the above-described form will be described with reference to FIGS. First, the overall manufacturing process will be described, and then the prepreg lamination state and the arrangement state of the prepreg reinforcing fibers to be laminated will be described.

  As described above, the frame 3 is formed by a prepreg in which a reinforcing fiber is impregnated with a synthetic resin. In this case, for example, the prepreg is configured in a state in which reinforcing fibers such as carbon fibers and glass fibers are aligned in a predetermined direction, or in a knitted sheet shape, and a thermosetting resin (for example, epoxy resin). And a thermoplastic resin (for example, nylon) impregnated as a matrix resin.

  First, the prepreg as described above is cut into a predetermined shape, and this is overlaid so as to form a plurality of layers. The number of prepregs to be stacked (number of layers) and the configuration of individual prepregs are not particularly limited. However, as described above, the bent portions 10a and 10b are formed in the frame 3, and the frame 3 can be used in use. In consideration of the load, the characteristics of the fishing rod to be mounted, the mounting portion, and the like, the type of prepreg and the conditions for stacking are arbitrarily adjusted.

  The prepregs laminated in this way are set in a mold 50 as shown in FIG. The mold 50 according to the present embodiment is composed of an upper mold 51 and a lower mold 52 that are divided vertically, and the stacked prepregs (denoted by reference numeral 20) are placed at predetermined positions on the lower mold 52. Set. Between the upper mold | type 51 and the lower mold | type 52, the cavity part 50a is formed according to the position where the laminated | stacked prepreg 20 is set, and the mold release agent is coated in the surface area | region.

  The upper mold 51 constituting the mold 50 is concave and the lower mold 52 is convex, and the cavity portion (this cavity is formed between the two so that the frame 3 is formed when both are pressed. 50a is formed (corresponding to the thickness of the frame 3). Then, when the prepreg 20 laminated in the sheet shape is placed on the lower mold 52, the bent forming convex parts 52a and 52b are formed at the positions corresponding to the bent parts 10a and 10b described above, and the upper mold 51 Are formed with bending recesses 51a and 51b corresponding to the bending protrusions 52a and 52b.

  The prepreg 20 may be set in a lower mold in a state where the entire prepreg 20 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 this embodiment, since the mold 50 is divided vertically as described above, the prepreg 20 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 a prepreg to the lower mold | type 52, the mounted prepreg 20 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 stage, the shape corresponding to the shape of the frame after molding, including the bent portion, is maintained, thereby preventing the occurrence of internal residual stress after molding, and the strength can be improved and stabilized. (At this stage, the prepreg is in an uncured state (including after temporary curing), and the bent portion is formed before heat curing).

  Thereafter, a heating step is performed, the matrix resin is cured and molded, and then a molded product (a plate-like body 30 having a bent portion) is taken out from the mold 50.

  In addition, when the above-described bent portion is pressed and cured by the mold 50, it is preferable that the bent portion is pressed relatively stronger than the front and rear regions. Thus, by strongly pressing the area of the bent portion, voids in the bent portions (10a, 10b) of the molded frame can be prevented, and the strength can be improved and stabilized. In addition, the bent portions 10a and 10b of the molded frame 3 can have a higher fiber ratio than the front and rear regions (fixed portions and supporting leg portions), so that the bent portions that are easily damaged are reinforced. It becomes possible to do.

  Next, the frame is cut out from the plate-like body 30 so as to have a predetermined shape. As described above, since the prepreg is a plate-like body in which a bent portion is formed after the heat-curing treatment, it is cut out by pressing, cut out with a liquid (water jet, etc.), cut out with a cutting tool (end mill, etc.), etc. By adopting an arbitrary method, as shown in FIG. 6, it becomes possible to cut out a plurality of frames 3 from one plate-like body 30, and it is possible to efficiently manufacture a lightweight and high-strength fishing line guide. It becomes possible.

  During this processing, it is preferable to simultaneously form the basic outer shape of the frame 3, that is, the ring holding portion 7 having the opening 7a, the support leg portion 8 having the opening 8a, etc., but these are formed in separate steps. It may be formed. In addition, the plate-like body 30 is not limited to a simple planar shape, but the laminated thickness is changed depending on the position, or the plate-like portion extends in a plurality of directions (T-shape, inverted Y-shape, etc.) Or a curved surface shape, or a plurality of plate-like portions may be combined.

  Next, detailed processing is performed as necessary. This detailed processing corresponds to, for example, forming the shape of the fixing portion 5 into a curved surface so that it can be easily placed on a fishing rod, or polishing the end of the fixing portion so as to facilitate winding and threading. .

  Next, a surface treatment of the frame is performed. 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 6 is attached to the portion of the opening 7a 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, when the frame 3 is formed by the prepreg as described above, a preferable arrangement mode of the prepreg will be described.

  The frame 3 of the present embodiment is composed of a plurality of fiber reinforced resin layers obtained by laminating prepregs in which reinforcing fibers are impregnated with a synthetic resin. In this embodiment, as shown in FIG. 5, an axial length direction fiber resin layer 21 in which reinforcing fibers are aligned along the axial length direction of the fishing rod, and a crossing direction having a predetermined angle with respect to the axial length direction of the fishing rod. And oblique fiber resin layers 22a and 22b in which reinforcing fibers are aligned, and a woven fabric layer 23 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. 6, the neutral axis is indicated by X) that is an intermediate position of the thickness of the frame. The directional fiber resin layer 21 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 22a and 22b are arranged by 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 23 is disposed by the prepreg. The axial length direction fiber resin layer 21 may have a plurality of layers (1 to 4 layers). The oblique fiber resin layers 22a and 22b may have different directions of 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. In other words, by setting the direction of the reinforcing fiber to three or more directions, it is possible to form a fishing line guide that is efficient, lightweight and excellent in strength, and has excellent strength even if the frame width is reduced. Obtainable. Further, in this manner, the frame 3 has the reinforcing fibers disposed in the axial direction in the neutral axis area, and the reinforcing fibers are disposed in the direction intersecting the axial length direction outside the neutral axis area, and the outermost layer. By providing a woven fabric layer 23 knitted with reinforcing fibers, it is possible to realize an improved strength and stabilized fishing line guide 1 without causing breakage or breakage even if it is greatly deflected, and efficiently. Weight reduction can be achieved.

  Further, in this configuration, the frame 3 has a longer length than the amount of reinforcing fibers (reinforcing fibers of the long-direction fiber resin layer 21) oriented in the longitudinal direction from the fixing portion 5 toward the ring holding portion 7. It is preferable that a large amount of reinforcing fibers (reinforcing fibers of the oblique fiber resin layers 22a and 22b) oriented in the intersecting direction having an angle are disposed. According to this, it is possible to make the fishing line guide 1 difficult to break even if the fishing line guide 1 is greatly bent and the frame 3 is bent by a large load in the direction of the arrow in FIG.

  Further, in this configuration, the frame 3 has a thickness of the prepreg (woven fabric layer 23) disposed in the outermost layer rather than the thickness of the prepreg (long-direction fiber resin layer 21) disposed in the neutral axis area. Is thinner. If it does in this way, specific strength will improve, peeling of the reinforced fiber from an edge part can be prevented, and a big deflection will be attained.

  Moreover, it is preferable to arrange | position the woven fabric layer 23 in the outermost layer of the flame | frame 3 like the arrangement | positioning structure of the above-mentioned prepreg. This is because the surface of the frame 3 is a part that is easily hit by other objects and is easily peeled off, and the reinforcing fibers are peeled off from the edge 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.

  Further, for such a woven fabric layer 23, as shown in FIG. 8, the width w of the main fiber knitted with reinforcing fibers (usually, a large number of reinforcing fibers are bundled to form a fiber bundle. Since the fiber bundle is knitted to form a woven fabric, the mesh is specified by the width of the fiber bundle), but the width W of the support leg portion 8 of the frame 3 (the width here is the minimum). It is preferable to use one that becomes smaller than the width of the corresponding part.

  By disposing such a woven fabric layer 23, it is possible to prevent the reinforcing fibers from peeling and breaking more reliably, and to improve the strength and stabilize the strength. Further, the bent portions 10a and 10b can be relatively strengthened, and a fishing line guide that is light in weight and excellent in strength balance can be obtained. Of course, it is preferable that the mesh width of the woven fabric layer 23 is also smaller than the minimum width at the fixed portions 5 and the ring holding portion 7.

  In the embodiment shown in FIG. 8, the direction of the knitted fabric of the woven fabric is along the axial direction AX, but this is 45 degrees ± 15 degrees or 45 degrees ± 30 degrees with respect to the longitudinal direction AX. It is preferable to incline. By inclining in this way, breakage and peeling of the reinforcing fiber can be prevented. Moreover, you may comprise the whole layer by the above woven fabric layers.

  Moreover, it is preferable to arrange | position the axial length direction fiber resin layer 21 in the intermediate | middle layer area | region of the flame | frame 3 like the above-mentioned structure. As a result, even if a bending force is applied to the frame 3 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.

  Further, it is preferable that the fiber ratio of the bent portions 10a and 10b is set higher than that of the front and rear regions. For example, as described in the above-described process, it is possible to increase the fiber ratio of the bent portion by increasing the pressing force in the bent portion region during heat forming, and the fiber ratio of the bent portion can be increased. By doing so, it is possible to obtain a fishing line guide that is not easily damaged even when the frame is bent due to the load acting.

  Instead of increasing the fiber ratio of the bent portion, as shown in FIG. 7, the thickness T at the bent portion is formed to be thicker than the thickness T1 at the fixed portion 5 and the thickness T2 at the support leg portion 8. May be. Thus, by making the bent portion thicker than other regions, it is possible to effectively prevent breakage at the bent portion. Of course, it is preferable to increase the thickness and increase the fiber ratio as described above.

  For the bent portion, the synthetic resin impregnation amount of the outer layer portion inside the bent portion (the side indicated by the symbol P of the bent portion 10a in FIG. 7) is larger than the synthetic resin impregnation amount of the neutral axis portion in the thickness direction. It is preferable to increase the number.

  As described above, since a large load often acts in the direction of the arrow in FIG. 7 when a tension by a fishing line acts on the frame portion, it is damaged from the outer layer portion (the side indicated by P) inside the bent portion. Is likely to occur. For this reason, by increasing the amount of resin impregnation on such a region side, it becomes possible to provide a fishing line guide that is not easily damaged even if the frame is bent by a 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 does not become heavy, 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.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously.

  In the present invention, the frame portion constituting the fishing line guide is constituted by a fiber reinforced prepreg, and the specific strength, specific rigidity, etc. are increased, and in particular, the prepreg as described above is provided so as not to be damaged in the bent portion region. This is characterized by the use of this arrangement mode. The prepreg constituting the above-described frame is not limited to the embodiment with respect to the configuration and type of reinforcing fiber, the elastic modulus, the resin impregnation amount, the thickness, and the like, and may be variously modified. Is possible.

  In addition, the fishing line guide has been described as being fixed to the fishing rod by threading or the like. However, for example, the fishing line guide may be configured as an idle guide that is slidably fitted to the fishing rod. If it is such an idle guide, the structure which does not form a bending part in the above-mentioned flame | frame 3 may be sufficient. That is, as shown in FIG. 9, the frame 3A is formed in a flat plate shape, and an opening 5d is formed on one end side as the fixing portion 5A (the opening 5d is provided on the fixing portion 5A), and the other end. On the side, an opening 7c that can fix the guide ring is formed as the ring holding portion 7A. Further, the support leg portion 8A that connects the fixing portion 5A and the ring holding portion 7A is formed with a lightening 8c as necessary. The sliding fixing ring 5c is attached to the opening 5d, and the unevenness formed on the inner surface of the cylindrical body by fixing a cylindrical body (not shown) to the opening 5d to which the sliding fixing ring 5c is attached. The strip portion and the fishing rod are engaged.

  As described above, the frame may have a configuration in which a bent portion is not formed according to the mounting position of the fishing rod, and the prepreg used in the frame constituting such a fishing line guide has a single layer structure of a woven fabric layer. Anyway. Of course, a laminated structure as described above may be used, and a bent portion may be formed separately. Alternatively, the portion (region indicated by reference numeral 5D) to which the sliding fixing ring 5c is attached is formed to be thicker than the ring holding portion 7A, but the overall thickness may be the same. It is possible to set arbitrarily.

  In addition, as described above, the prepreg constituting the frame can efficiently increase the strength while reducing the weight if the orientation direction of the reinforcing fiber is three or more when viewed in a plan view in a stacked state. Although it is possible to improve, the directing direction of the reinforcing fibers of the prepreg constituting each layer and the stacking position thereof are not particularly limited and can be appropriately modified. In this case, as described above, the outermost layer of the frame is preferably provided with a woven fabric layer so that breakage and the like can be effectively prevented.
