  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 viewed from the direction of arrow A, and FIG. 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. Further, the fishing line guide is attached so that the ring holding part is on the tip side and the fixing part is on the side of the head. In the following, the front side means the tip side, and the rear side is the base end side (the base side) Side).

  The fishing line guide 1 includes a frame 3 formed of a laminated material having a plurality of fiber reinforced resin layers in which fiber reinforced prepregs (hereinafter referred to as prepregs) in which reinforced fibers are impregnated with synthetic resin are laminated (configuration of prepregs). The detailed description of the method for manufacturing the frame and the frame will be given 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 into 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 that connects the two, and is formed in a plate shape in which the width in the left-right direction is larger than the thickness of the ring holding portion 7 in the axial direction (arrow A direction in FIG. 1; front-rear direction). .

  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. As will be described later, the support legs 8 may be formed along the vertical direction (defined as the longitudinal axis X of the frame) when the fishing line guide is viewed from the front (the axial length direction of the fishing rod). As shown in the figure, it may be formed so as to be inclined with respect to the vertical direction.

  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.

  In addition, the bent portions 10a and 10b formed in 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.

  As will be described later, the frame 3 is formed by pressing or the like from a prepreg in which a bent portion having a configuration as described above is formed in advance (which is a plate-like body after thermoforming). At this time, it is formed to have a predetermined outer shape. In the present embodiment, as shown in FIG. 2, the support leg portion 8 rising from the end portion of the fixed portion 5 via the first bent portion 10a gradually becomes wider as it moves upward, and the guide ring 6 is attached. It is integrally connected to a substantially circular ring holding portion 7 in which an opening 7a to be attached 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 with reference to FIGS. 4 and 5, and then the laminated state of a plurality of prepregs constituting the frame and the arrangement state of reinforcing fibers of the laminated prepregs will be described. To do.

  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 includes an upper mold 51 and a lower mold 52 that are divided vertically, and the laminated prepreg (laminated material 20) 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 part 50a is formed according to the position where the laminated material 20 is set, and the mold release agent is coated in the surface area.

  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 laminated material 20 is placed on the lower mold 52, the bent forming convex parts 52a and 52b are formed at positions corresponding to the bent parts 10a and 10b, and the upper mold 51 is bent. Bending formation concave portions 51a and 51b are formed corresponding to the convex portions 52a and 52b.

  Note that the laminated material 20 may be set in a 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, as described above, since the mold 50 is divided vertically, the laminated material 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 the laminated material 20 to the lower mold | type 52, the laminated material 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, each 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. 5, 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.

  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.

  Next, when the frame 3 is formed by the prepreg as described above, a preferable arrangement mode of the prepreg will be described with reference to FIG. The fishing line guide of FIG. 6 is attached to the fishing rod 40 in such a direction that the ring holding portion 7 is on the front side (the tip side) and the fixing portion 5 is on the rear side (the main rod side). FIG. 6 is a view of the frame 3 as viewed from the front side (the tip side).

  As described above, the frame 3 is constituted by the laminated material 20 having a plurality of fiber reinforced resin layers in which prepregs in which reinforcing fibers are impregnated with synthetic resin are laminated in the front-rear direction. Layer prepregs are used. Here, for the sake of convenience, the first layer 20a, the second layer 20b, the third layer 20c, and the fourth layer 20 are sequentially moved from the front side (the tip side) to the rear side (the former side). It is defined as a layer 20d, a fifth layer 20e, a sixth layer 20f, a seventh layer 20g, and an eighth layer 20h (in such a laminated structure, a gap between the fourth layer 20d and the fifth layer 20e, which is the center on the laminated side, is defined as It becomes the center C of the laminated material 20). In FIG. 6, the vertical direction when the fishing line guide is viewed from the front (the axial direction of the fishing rod) is defined as the longitudinal axis X of the frame, and the fiber direction in each layer is indicated by diagonal lines or lattice lines.

  The front and rear surfaces (the first layer 20a and the eighth layer 20h) that are the outermost layers of the laminated material 20 are constituted by fiber reinforced resin layers of woven fabric. In this case, as shown in FIG. 6, the reinforcing fibers constituting the woven fabric are set so as to be in a direction along the longitudinal axis X and a direction (horizontal direction) perpendicular thereto. Is desirable.

  The inner layer sides (second layer 20b and seventh layer 20g) of the first layer 20a and the eighth layer 20h are aligned in one direction along the longitudinal axis X (which may not exactly match). It is comprised by the axial direction fiber reinforced resin layer which consists of a reinforced fiber.

  Further, the inner layer side (the third layer 20c and the sixth layer 20f) is an oblique fiber reinforced resin in which the reinforcing fibers are obliquely inclined rightward (defined by +) with respect to the longitudinal axis X when viewed from the front. Consists of layers. In this case, it is only necessary to incline in the right direction with respect to the longitudinal axis X, but the inclination angle with respect to the longitudinal axis X is preferably in the range of 10 ° to 60 °, and the oblique angles of the reinforcing fibers of both layers are It does not have to match exactly.

  Further, the inner layer side (the fourth layer 20d and the fifth layer 20e) is an oblique fiber reinforced resin in which the reinforcing fibers are inclined leftward (defined by −) with respect to the longitudinal axis X when viewed from the front. Consists of layers. In this case, it is only necessary to incline leftward with respect to the longitudinal axis X, but the inclination angle with respect to the longitudinal axis X is preferably in the range of −10 ° to −60 °, and the oblique angles of the reinforcing fibers of both layers Does not have to match exactly.

  Therefore, the layers before and after the center C in the laminated material 20 are both oblique fiber reinforced resin layers (the fourth layer 20d and the fifth layer 20e) in which the reinforcing fibers are inclined in the left direction, Both are oblique fiber reinforced resin layers (third layer 20c and sixth layer 20f) in which the reinforcing fibers are inclined to the right. That is, the oblique fiber reinforced resin layer in which the reinforcing fibers are inclined in the opposite directions with respect to the longitudinal axis X of the frame is disposed on one side and the other side with respect to the center C of the laminated material 20. (The fourth layer 20d and the sixth layer 20f, and the third layer 20c and the fifth layer 20e).

  Further, in the aspect of the present embodiment, oblique fiber reinforced resin layers in which reinforcing fibers are inclined in the same direction with respect to the longitudinal axis X of the frame are arranged on one side and the other side with respect to the center C of the laminated material 20. The fourth layer 20d and the fifth layer 20e, and the third layer 20c and the sixth layer 20f are provided.

  According to the configuration of the laminated material 20 as described above, the weight of the frame itself can be reduced, and a fishing line guide excellent in specific strength, specific rigidity, and flexibility can be constructed. In particular, on the one side and the other side with respect to the center C of the laminated material 20, the oblique fiber reinforced resin layers in which the reinforcing fibers are inclined in directions opposite to each other with respect to the longitudinal axis X of the frame are disposed. Even when a fish is caught, a load is applied to the frame 3 of the fishing line guide, and even if the fish is bent back and forth or twisted, the bending direction does not deviate, so that damage and the like can be effectively suppressed. Further, since the location where the fishing line hits the guide ring is difficult to concentrate due to the bending of the frame 3, it is possible to prevent the fishing line from being worn.

  Further, in the configuration described above, the reinforcing fibers are in the same direction with respect to the longitudinal axis X of the frame in the direction away from the center C in the stacking order on one side and the other side of the center C of the laminated material 20 respectively. Since the slanted fiber reinforced resin layers are inclined in the same order, the bending rigidity and the torsional rigidity can be made the same before and after the frame of the fishing line guide 1, and the frame is constant against the load. This will prevent distortion in the direction.

  Moreover, the laminated material 20 having the above-described configuration includes axial fiber reinforced resin layers (second layer 20b and seventh layer 20g) made of reinforcing fibers aligned in one direction along the longitudinal axis X. As a result, the bending rigidity in the longitudinal axis direction can be increased.

  Furthermore, since the laminated material 20 having the above-described configuration includes the fiber reinforced resin layer of the woven fabric on the front and rear surfaces (the first layer 20a and the eighth layer 20h) which are the outermost layers, the reinforced fiber even when the fishing line contacts It is difficult to cause tearing or peeling, and the strength can be improved and stabilized, and the inner fiber-reinforced resin layer can be effectively protected.

  For the fiber reinforced resin layers 20a and 20h of such a woven fabric, as shown in FIG. 7, the mesh width w of the main fibers knitted with the reinforcing fibers (usually, many reinforcing fibers were bundled. The fiber bundle is configured in a state, and since the fiber bundle is knitted to form a woven fabric, the mesh is specified by the width of the fiber bundle), and the width W of the support leg portion 8 of the frame 3 (here It is preferable to use a width that is smaller than the minimum width corresponding to the width of the part.

  By disposing such fiber reinforced resin layers 20a and 20h of woven fabric, it is possible to prevent the reinforcing fibers from being peeled and damaged more reliably, and to improve and stabilize the strength. In addition, the above-described 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 widths of the fiber reinforced resin layers 20a and 20h of the woven fabric be smaller than the minimum widths in the fixed portions 5 and the ring holding portions 7 as well. .

  In the arrangement mode shown in FIG. 7, regarding the woven fabric, the direction of the stitches is along the longitudinal axis X of the frame, but it is preferable to incline the knitted fabric by a predetermined angle with respect to the longitudinal axis X. By inclining in this way, the reinforcing fiber can be directed in the direction along the extending direction of the support leg 8 configured as described above, and in the direction perpendicular thereto, and the reinforcing fiber can be broken or peeled off. It can be effectively prevented.

  Further, in the above-described configuration, the oblique fiber reinforced resin layers (the fourth layer 20d and the sixth layer 20) provided on the one side and the other side of the center C with the reinforcing fibers inclined in opposite directions, respectively. For the layer 20f and the third layer 20c and the fifth layer 20e), it is preferable to use prepregs having the same fiber amount.

  By using such a prepreg, the front and rear rigidity of the frame can be easily made the same, and the rigidity balance can be obtained in the front and rear. The pair of left and right support legs 8 are formed of the same laminated material 20 formed by laminating the same prepreg in the same laminating order, and balances rigidity and the like.

  FIG. 8 is a view showing a second embodiment of the frame portion, and is an enlarged view showing a laminated structure of prepregs constituting the frame.

  The laminated material 22 of this embodiment uses a total of four prepregs. Similar to the above-described embodiment, the first layer 22a, the second layer 22b, the third layer 22c, in order, as the laminated material 22 moves from the front side (point side) to the rear side (general side). It is defined as the fourth layer 22d (in such a stacked structure, the center between the second layer 22b and the third layer 22c is the center C of the stacked material 22 in the stacking order).

  The front and rear surfaces (the first layer 22a and the fourth layer 22d) that are the outermost layers of the laminated material 22 are constituted by fiber reinforced resin layers of woven fabric.

  Further, the inner layer side (second layer 22b) of the first layer 22a is an oblique fiber reinforced resin layer in which the reinforcing fibers are inclined to the right, and the inner layer side (third layer) of the fourth layer 22d. 22c) is an oblique fiber reinforced resin layer in which the reinforcing fibers are inclined to the left. That is, an oblique fiber reinforced resin layer in which reinforcing fibers are inclined in opposite directions with respect to the longitudinal axis X of the frame is disposed on one side and the other side with respect to the center C of the laminated material 22. Yes.

  According to the frame having such a configuration, as in the above-described embodiment, even if a load is applied to the frame 3 of the fishing line guide to bend back and forth or torsion occurs, the bending direction does not deviate, so that damage or the like is effective. Can be suppressed. Further, since the location where the fishing line hits the guide ring is difficult to concentrate due to the bending of the frame 3, it is possible to prevent the fishing line from being worn. Furthermore, in this embodiment, since the weight can be reduced by reducing the number of layers, the configuration is suitable for the fishing line guide on the tip side of the fishing rod.

  FIG. 9 is a view showing a third embodiment of the frame portion, and is an enlarged view showing a laminated structure of prepregs constituting the frame.

  The laminated material 24 of this embodiment uses nine layers of prepregs as a whole. Similar to the above-described embodiment, the first layer 24a, the second layer 24b, the third layer 24c, in order, as the laminated material 24 moves from the front side (point side) to the rear side (general side). The fourth layer 24d, the fifth layer 24e, the sixth layer 24f, the seventh layer 24g, the eighth layer 24h, and the ninth layer 24i are defined. With such an odd number of layers, the fifth layer 24e forms a core material layer that becomes the center C in the stacking order.

  The front and rear surfaces (the first layer 24a and the ninth layer 24i), which are the outermost layers of the laminated material 24, are composed of fiber reinforced resin layers of woven fabric, and the inner layer side (the second layer 24b and the eighth layer 24h) It is comprised by the axial direction fiber reinforced resin layer which consists of a reinforced fiber arranged in one direction along the longitudinal axis X. As shown in FIG.

  In addition, the inner layer side (the third layer 24c and the seventh layer 24g) has an oblique fiber reinforced resin layer obliquely inclined rightward with respect to the longitudinal axis X and an oblique fiber reinforced resin obliquely inclined leftward. The inner layer side (the fourth layer 24d and the sixth layer 24f) is inclined to the left with respect to the longitudinal axis X, and is inclined to the right. It is comprised by the diagonal fiber reinforced resin layer.

  Further, the core material layer 24e serving as the center C is configured by an axial fiber reinforced resin layer made of reinforcing fibers aligned in one direction along the longitudinal axis X.

  Therefore, the layer before and after the center C (core material layer 24e) in the laminated material 24 is provided with the oblique fiber reinforced resin layer in which the reinforcing fibers are inclined in directions opposite to each other with respect to the longitudinal axis X of the frame. (The fourth layer 24d and the sixth layer 24f), and the outer layer is also in a state in which an oblique fiber reinforced resin layer in which reinforcing fibers are inclined in opposite directions is disposed (third layer 24c). And the seventh layer 24g).

  Furthermore, the laminated material 24 is in a state in which the fiber reinforced resin layers on both sides with respect to the center C (core material layer 24e) are laminated so that the fiber directions are symmetrical with each other toward the outer layer.

  According to the frame having such a configuration, as in the above-described embodiment, even if a load is applied to the frame 3 of the fishing line guide to bend back and forth or torsion occurs, the bending direction does not deviate, so that damage or the like is effective. Can be suppressed. Further, since the location where the fishing line hits the guide ring is difficult to concentrate due to the bending of the frame 3, it is possible to prevent the fishing line from being worn. Further, in the present embodiment, the core material layer 24e serving as the axial fiber reinforced resin layer is disposed in the center, so that a bending force is applied to the frame 3 by the tension of the fishing line along the axial length direction. However, it is possible to efficiently increase the specific rigidity in that direction while reducing the weight.

  Further, in this embodiment, the fiber reinforced resin layers on both sides with respect to the center C (core material layer 24e) are laminated so that the fiber directions are symmetrical to each other toward the outer layer. When a twisting force is applied, it is possible to improve specific strength against twisting in either the left or right direction.

  FIG. 10 is a view showing a fourth embodiment of the frame portion, and is an enlarged view showing a laminated structure of prepregs constituting the frame.

  In this embodiment, the supporting leg portion 8A for connecting the fixing portion 5 and the ring holding portion 7 is formed in a single plate shape without forming the central window portion (opening 8a) as in the above-described embodiment. is doing. As described above, the shape of the support leg portion 8A can be appropriately changed according to, for example, the type of fishing rod, the rod to which the fishing line guide is attached, and is formed in a plate shape as shown in the figure. The support legs can also be modified as appropriate by bending the middle part or chamfering. And as for the laminated material 26 of this embodiment, 10 layers of prepregs are used as a whole, and the laminated material 26 is moved from the front side (the tip side) to the rear side (the former side) similarly to the above-described embodiment. As the transition proceeds, the first layer 26a, the second layer 26b, the third layer 26c, the fourth layer 26d, the fifth layer 26e, the sixth layer 26f, the seventh layer 26g, the eighth layer 26h, and the ninth layer are sequentially arranged. The layer 26i and the tenth layer 26j are defined (in such an even number of layers, the center C of the laminated material 26 is between the fifth layer 26e and the sixth layer 26f).

  The front and back surfaces (the first layer 26a and the tenth layer 26j) that are the outermost layers of the laminated material 26 are configured by fiber reinforced resin layers of woven fabric, and the inner layer side (the second layer 26b and the ninth layer 26i) It is comprised by the axial direction fiber reinforced resin layer which consists of a reinforced fiber arranged in one direction along the longitudinal axis X. As shown in FIG.

  Further, the inner layer side (the third layer 26c and the eighth layer 26h) is composed of an oblique fiber reinforced resin layer that is inclined in the right direction with respect to the longitudinal axis X, and the inner layer side (the fourth layer). 26d and the seventh layer 26g) are each composed of an oblique fiber reinforced resin layer obliquely inclined rightward with respect to the longitudinal axis X and an oblique fiber reinforced resin layer obliquely inclined leftward.

  Further, the layers (fifth layer 26e and sixth layer 26f) on both sides with respect to the center C of the laminated material 26 are opposite to each other with respect to the longitudinal axis X (the fifth layer 26e is in the left direction and the sixth layer 26f is in the right direction). ) Is provided with an oblique fiber reinforced resin layer in which the reinforcing fibers are inclined.

  Accordingly, the layers before and after the center C in the laminated material 26 are in a state in which the oblique fiber reinforced resin layers in which the reinforcing fibers are inclined in directions opposite to each other with respect to the longitudinal axis X of the frame (fifth). The layer 26e and the sixth layer 26f), and the outer layers are also provided with oblique fiber reinforced resin layers in which the reinforcing fibers are inclined in opposite directions (fourth layer 26d and seventh layer 26g). .

  Also in the frame having such a configuration, as in the above-described embodiment, even if the fishing line guide frame 3 is subjected to a load and bends back and forth or twists, the bending direction does not deviate. It becomes possible to suppress. Further, since the location where the fishing line hits the guide ring is difficult to concentrate due to the bending of the frame 3, it is possible to prevent the fishing line from being worn. In particular, also in the present embodiment, as in the third embodiment, the fiber reinforced resin layers on both sides with respect to the center C (between the fifth layer 26e and the sixth layer 26f) are in the fiber direction toward the outer layer. Are laminated so as to be symmetrical to each other. Therefore, when a force for twisting the frame is applied, it is possible to improve specific strength against twisting in either the left or right direction.

  In the configuration shown in FIGS. 6, 8, 9, and 10, the laminated materials 20, 22, 24, and 26 that constitute the frame 3 are axial fibers directed from the fixing portion 5 to the ring holding portion 7. It is preferable that the amount of reinforcing fibers in the oblique fiber resin layer is larger than the amount of reinforcing fibers in the resin layer. 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.

  In the above-described configuration, it is preferable that the bent portions 10a and 10b have a higher fiber ratio than the front and rear regions. For example, as explained in the manufacturing process described above, by increasing the pressing force in the region of the bent portion during heat molding, the resin can flow out and the fiber ratio of the bent portion can be increased. By comprising, it becomes possible to make it a fishing line guide which is hard to break even if a load acts and the frame bends.

  In place of increasing the fiber ratio of the bent portion, as shown in FIG. 11, the thickness T of the bent portion is set to the thickness T1 of the fixed portion 5 or the thickness T2 of the support leg portion 8 (support leg portion 8A). It may be formed thicker. 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.

  Further, with respect to the bent portion, the amount of synthetic resin impregnation in the outer layer portion inside the bent portion (the side indicated by the symbol P of the bent portion 10a in FIG. 11) is more than the amount of synthetic resin impregnated in the neutral axis portion in the thickness direction. It is preferable to increase the number.

  As described above, since a large load often acts on the frame portion in the direction of the arrow in FIG. 11 when the tension by the fishing line is applied, the frame portion 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.

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 enhanced, and in particular, the prepreg as described above is provided so that no breakage or the like occurs in the bent region. This is characterized by the use of this arrangement mode. About the prepreg constituting the above-mentioned frame, the type of reinforcing fiber, the elastic modulus, the direction of orientation (inclination angle), the configuration of the resin impregnation amount, the thickness, etc., and the lamination state are limited to the embodiment. However, various modifications are 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. 12, the frame 3A is formed in a flat plate shape, and an opening 5d is formed as a fixing portion 5A on one end side (the opening 5d is provided in 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 8B that connects the fixed 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.
