Explanatory drawing of the laminated molded body which forms a part of fishing line guide. Explanatory drawing of one process which manufactures a fishing line guide. Explanatory drawing of one process which forms the frame of a fishing line guide. The enlarged view of the fixing | fixed part of the fishing line guide of FIG. Explanatory drawing of the state which attached the fishing line guide to the rod.

1 and 2 show a fishing line guide 10 according to an embodiment of the present invention. The fishing line guide 10 of this embodiment is formed as an outer guide that prevents the fishing line from adhering to the outer surface of a fishing rod 8 of a fishing rod. It can be attached to a required position on the outer periphery of the soot tube 8 formed with a slight gradient, and can be fixed using appropriate fixing means such as a spool, a thread stopper, or an adhesive. If necessary, it is held at a required position by appropriate friction holding means, and if necessary, it is moved back and forth in the axial direction parallel to the axis C of the tub tube 8 from the front tip side to the rear base side. It may be moved and held at a required position by a frictional force.

  In the same manner as usual, the soot tube 8 is a deflection direction in which a fiber reinforced prepreg sheet obtained by impregnating a reinforcing fiber such as carbon fiber with a synthetic resin such as an epoxy resin is inclined at an appropriate angle with respect to the circumferential direction, the axial length direction, or the axial length direction. It is possible to use a hollow soot tube in which the plurality of fiber layers are laminated by winding them together.

  The fishing line guide 10 attached to the rod 8 includes a plate-like frame 18 having a fishing line guide portion 14 that holds the guide ring 12 and a support leg portion 16 that supports the fishing line guide portion 14 on one end side. The frame 18 is integrally formed with a fixing portion 20 on the other end side of the support leg portion 16, and the fixing portion 20 is fixed on the outer surface of the tub tube 8 by fixing means such as bobbin winding or adhesion.

  A through hole 14a for holding the guide ring 12 is formed in the fishing line guide portion 14, and the guide ring 12 held through the through hole 14a has a fishing line guide on the inner surface formed by a smooth annular curved surface. The fishing line is guided through a fishing line conduction hole having a surface 12a and surrounded by the fishing line guide surface 12a.

  In FIG. 1, the guide ring 12 is oriented so that the center axis O of the fishing line passage hole is substantially parallel to the axis C of the rod 8 and is greatly expanded in a funnel shape as shown on the left side of FIG. It is shown in a state of being held by the frame 18 with the end 12b on the side facing the fishing reel (not shown) side. The opposite end portion 12c slightly expands in diameter toward the opposite side to the end portion 12b. The outer peripheral side edge portions of these end portions 12b and 12c are engaged with the peripheral edge portion of the through hole 14a from both sides of the fishing line guide portion 14, and are prevented from coming off.

  The guide ring 12 is preferably formed of a hard material having higher wear resistance than the frame 18, such as silicon carbide (SiC), alumina oxide, tungsten carbide, ceramic or metal.

  The fishing line guide portion 14 for holding the guide ring 12 has an outer peripheral edge formed in a ring shape having a larger diameter than the end portion 12b on the enlarged diameter side of the guide ring 12, and the guide ring 12 is fitted into the through hole 14a. When held together, the outer peripheral edge protrudes to the outer peripheral side of the guide ring 12. As a result, even if the radial dimension of the end portion 12b of the guide ring 12 is short, the fishing line is reliably guided together with the guide ring 12, and is arranged at a required distance from the outer surface of the rod pipe 8 by the support leg portion 16. The

  The support leg portion 16 has outer edge portions 16 a extending in a smooth curved shape from the outer peripheral edge portion of the fishing line guide portion 14 on both sides, and these outer edge portions smoothly transition to both edge portions of the fixing portion 20. Thereby, sufficient strength for holding the fishing line guide portion 14 at a required position is secured, and further, formation of a corner portion where the fishing line is easily caught is prevented.

  When the width between the outer edge portions 16a of the support leg portion 16 is larger than necessary to maintain the required strength, a recess 16b as shown in FIG. 2 is formed through the plate thickness direction. Also good. The number of such recesses 16b is not limited to one, and a plurality of such recesses 16b may be provided, or may be provided in one or both along the axial direction of the central axis O of the fishing line passage hole without being formed to penetrate therethrough. Good. In any case, it is preferable to form a smooth outer surface having no corners or protrusions that are easily hooked by fishing lines.

  The support leg portion 16 is integrally formed with a fixing portion 20 at an end portion separated from the fishing line guide portion 14, and the frame 18 can be fixed to the rod tube 8 via the fixing portion 20. The fixed portion 20 has a plate shape having a width smaller than the outer diameter of the soot tube 8 to be attached, and the back surface 22 opposite to the support leg portion 16 is placed on the soot tube 8. Form a surface.

  The surface 24 on the side of the support leg 16 is formed in a curved shape that is gradually curved toward the side of the tubule 8 along the longitudinal direction of the fixed part 20 on the free end side separated from the support leg 16. In addition, the surface 24 may have a curved shape that gradually curves toward the side tube 20 toward the side edge portions 20 a and 20 a along the width direction of the fixed portion 20. By forming the surface 24 of the fixing portion 20 in such a curved surface shape, a smooth outer surface without a corner portion or a convex portion that is easy to catch a fishing line when fixed to the rod tube 8 can be formed. , Winding and threading are easy.

  The back surface 22 of the fixed portion 20 can be formed as a flat surface as shown in FIG. 2, but may be formed as a curved surface along the outer surface of the tub tube 8. In the case of forming on the curved surface, the mounting surface is suitably adapted to the outer surface shape of the soot tube 8, and the fixing force to the soot tube 8 can be improved.

  As described above, the fixed leg 20 and the fishing line guide 14 are connected to each other, and the support leg 16 that places the fishing line guide 14 in the required direction and position is provided with the fixed bent part 26 and the guide bent part 28. is there. By adjusting the bending angles of these bent portions 26 and 28, the postures of the fishing line guide portion 14 and the guide ring 12 with respect to the fixed portion 20 can be changed. The guide ring 12 shown in FIG. 1 has a central axis O arranged in parallel to the axis C of the soot tube 8, and is obviously not limited to this and can be oriented in various directions.

  The inclination angle α1 of the fixed-side bent portion 26 formed between the intermediate portion 16a of the support leg portion 16 and the fixed portion 20 is in the range of 30 to 90 degrees, and is formed between the intermediate portion 16a and the fishing line guide portion 14. The inclination angle α2 of the guide side bent portion 28 is in the range of 0 to 45 degrees, and the angle obtained by adding both inclination angles, that is, the angle of the fishing line guide section 14 with respect to the fixed portion 20 is 30 degrees or more and 100 degrees or less. Is preferred.

  The frame 18 having the structure as described above is formed of a laminated molding material 30 in which at least a part including the fixing portion 20 is formed by laminating a fiber reinforced prepreg in which a reinforcing fiber is impregnated with a synthetic resin to form a plate shape. When the entire frame 18 is formed of the laminated molding material 30, the manufacturing process is simplified and the frame 18 can be formed into a lightweight structure.

  FIG. 3 shows an example of a laminated structure of the laminated molding material 30 in which the direction in which the reinforcing fibers are aligned is oriented in various directions. Such a laminated molding material 30 may be formed by laminating a plurality of fiber reinforced prepregs impregnated with a thermosetting resin such as an epoxy resin as a matrix resin on a reinforcing fiber such as carbon fiber or glass fiber. It is also possible to use a thermoplastic resin instead of the thermosetting resin.

  The laminated molded body 30 has a fiber reinforced resin layer 32 in the longitudinal direction in which the reinforcing fibers extend along the longitudinal direction of the fixing portion 20 at the center in the thickness direction, and the reinforcing fibers are disposed above and below the longitudinal direction of the fixing portion 20. The fiber reinforced resin layers 34 and 36 in the intersecting direction oriented in the direction intersecting with the fiber are disposed, and the woven fabric layers 38 and 38 woven with the reinforcing fibers are disposed outside the fiber reinforced resin layers in the intersecting direction. It is. A symbol M indicates a neutral surface in the thickness direction of the laminated molded body 30.

  As shown in FIGS. 1 and 2, the fixing portion 20 is not only formed in an elongated plate shape along the axis C of the soot tube 8, but, for example, the circumferential dimension of the soot tube 8 is the soot tube. It is also possible to form longer than the axial length direction of 8, or the bent portion 26 can be formed in a smooth curved shape.

  The longitudinal fiber reinforced resin layer 32 disposed at the center in the thickness direction improves the bending balance of the rod tube 8 and improves and stabilizes the strength of the rod tube 8 and the fishing guide 10. It is preferable to form the reinforcing fiber having an elastic modulus (tensile elastic modulus) smaller than the elastic modulus (tensile elastic modulus) of the reinforcing fiber in the axial length direction. Furthermore, most of the reinforcing fibers (for example, 50% or more or 70% or more) arranged in the fixed portion have an elastic modulus (tensile elasticity) smaller than the elastic modulus (tensile elastic modulus) of the reinforcing fibers in the axial direction of the tub tube 8. It is preferable to form the reinforcing fiber having a ratio).

  The fiber reinforced resin layer 32 is formed by stacking a plurality of fiber reinforced prepregs in which reinforcing fibers are aligned in one direction at an angle of 0 ° ± 5 ° (or 0 ° ± 10 °) with respect to the axial length direction of the tub tube 8. It is preferable to form them.

  The fiber reinforced resin layers 34 in the intersecting direction are each oriented in a direction intersecting at a preferred angle of approximately 45 degrees within a range of 25 to 65 degrees with respect to the longitudinal direction of the fixed portion 20 and oriented in opposite directions. The inner oblique fiber layer 34a and the outer oblique fiber layer 34b are formed. Similarly, the cross-direction fiber reinforced resin layer 36 disposed on the opposite side across the longitudinal fiber reinforced resin layer 32 is also approximately 45 in the range of 25 to 65 degrees with respect to the longitudinal direction of the fixed portion 20. It has an inner oblique fiber layer 36a and an outer oblique fiber layer 36b whose degrees intersect at a preferred angle and are oriented in opposite directions.

  The oblique fiber layers 34 a, 34 b, 36 a, 36 b of the fiber reinforced resin layers 34, 36 each have a reinforcing fiber of 45 ° ± 15 ° (or 45 ° ± 30 °) with respect to the axial length direction of the soot tube 8. It is preferable to form a fiber reinforced prepreg aligned in one direction at an angle so as to overlap the fiber reinforced resin layer 32 at the center.

  By disposing the fiber reinforced resin layers 34 and 36 in the intersecting direction on both sides in the thickness direction of the fiber reinforced resin layer 32 in the longitudinal direction, the weight of the fishing line guide 10, especially the fixing portion 10 is reduced, and the strength is improved and stabilized. Can be achieved.

  The fiber amount of the reinforcing fibers formed by the fiber reinforced resin layers 34 and 36 in the intersecting direction and the woven fabric layer 38 to be described later is at least half (1/2 or more) of the entire reinforcing fiber amount forming the fixing portion 20. Thus, when attached to the soot tube 8, the bending balance of the soot tube 8 can be improved, the stress concentration can be relaxed, and the strength can be improved.

  The woven fabric layer 38 disposed outside the fiber reinforced resin layers 34 and 36 in the intersecting direction can be formed by interweaving, for example, fiber bundles made of a plurality of reinforcing fibers as the reinforcing fibers. As the weaving structure of the woven fabric layer 38, various woven structures such as a biaxial woven fabric in which fiber bundles extending in two directions are combined or a triaxial woven fabric in which fiber bundles extending in three directions are combined are formed. It is possible. In any case, the direction of the main fibers or fiber bundles of the fabric layer 38 is inclined with respect to the longitudinal direction of the fixing portion 20 (in the range of 45 ° ± 15 ° or 45 ° ± 30 °), and is relative to the longitudinal direction. It is preferable to arrange them symmetrically.

  The woven fabric layer 38 includes reinforcing fibers (fiber bundles) extending at an angle of 45 ° ± 15 ° with respect to the axial length direction and reinforcing fibers (fiber bundles) extending at an angle of 0 ° to 70 ° with respect to the axial length direction. ) And a fiber reinforced prepreg formed by weaving. The fiber reinforced prepreg forming the woven fabric layer 38 has a resin content (RC: wt%) greater than that of the fiber reinforced prepreg in the axial length direction forming the fiber layer 32 in the axial length direction.

Fabric layer 38 of this is the size of the stitches formed by the fiber bundles intersect one another, is preferably formed smaller than the minimum width portion of the support leg 16 (for example, sites of both sides of the recess 16b). In particular, it is preferable to reduce the size of the stitches at the bent portion 26 and to reduce the size of the fixing portion 20 and the fishing line guide portion 14 as well.

  By disposing such a fabric layer 38 on the outermost side, it is possible to prevent the reinforcing fibers from peeling from the outer layer and stabilize the strength.

  These reinforcing fibers forming the fiber reinforced resin layers 34 and 36 in the cross direction may have the same elastic modulus as the reinforcing fibers forming the fiber reinforced resin layer 32 in the longitudinal direction.

  In addition, when the fiber bundle of the fabric layer 38 is formed by combining fiber bundles extending in multiple directions of three or more directions, the fiber reinforced resin layer 32 in the longitudinal direction is omitted, and the fibers of the laminated molding 30 It is also possible to form the reinforced resin layer entirely from the fabric layer 38.

  4 to 6 show an outline of a manufacturing process for manufacturing the frame 18 made of such a laminated molding material 30 using the molds 40 and 42. FIG.

  A fiber reinforced prepreg sheet (not shown) that forms each of the fiber reinforced resin layers 32, 34, and 36 and the fabric layer 38 is cut into a predetermined shape, and the fiber direction is overlapped along the fiber direction of the laminate 30 described above. . The number of fiber-reinforced prepreg sheets or the number of layers to be laminated can be arbitrarily adjusted according to the type of fiber-reinforced prepreg sheets and the conditions for stacking. For example, the entire required amount of the laminated molded material 30 is overlapped. However, by dividing into a plurality of times, it is possible to set the molds 40 and 42 with high accuracy in a state in which the movement of the reinforcing fibers in each fiber-reinforced prepreg sheet is reduced.

  The molds 40 and 42 are preferably formed with a plurality of corresponding recesses 40a and 42a. These molds 40 and 42 are coated with a release agent in advance, and a fiber reinforced prepreg sheet laminated in accordance with the recesses 40a and 42a is set. The fiber reinforced prepreg sheets may be set in a state where they are overlapped in advance, or may be set one by one. Since the illustrated molds 40 and 42 are divided vertically by sandwiching the neutral surface M (FIG. 3) of the laminated molding material 30, a fiber-reinforced prepreg sheet is placed on the lower mold 40. The mold 40 can be held in accordance with the shape. The surface on which the recess 40a is formed may be disposed horizontally, may be inclined, and can be disposed in an appropriate direction.

  After the fiber reinforced prepreg is set in the mold 40, the fiber reinforced prepreg is pressurized with the upper mold 42 and fixed to the mold 40. At this time, the bent portions 26 and 28 are formed in the fiber reinforced prepreg sheet in an uncured state (including after temporary curing) and held in a shape corresponding to the shape of the frame 18. Thereby, generation | occurrence | production of the internal residual stress after shaping | molding can be prevented, and a strength improvement and stabilization can be aimed at. The pressing of the mold 42 against the mold 40 can be performed by using a fastening tool or a pressing tool in addition to pressing by hand.

  When the pressure is applied, the bent portions 26 and 28, particularly the bent portion 26 bent at a large angle, are formed by applying a relatively stronger pressure than the adjacent portions such as the fixed portion 20 and the support leg portion 16, thereby forming the bent portion 26. , 28 can be prevented from generating voids, and strength can be improved and stabilized.

  Thereafter, the fiber-reinforced prepreg sheet is heat-cured and taken out from the molds 40 and 42 as a laminated molding material 30 formed into a predetermined shape.

  As shown in FIG. 5, the laminated molding material 30 taken out from the molds 40 and 42 is formed as a band-like plate-like body 44, and is formed in a state in which a large number of parts to be formed on the frame 18 are connected. The plate-like body 44 is not limited to a long belt-like shape, and may be formed, for example, in a T shape or a Y shape. Moreover, not only the site | part which forms the flame | frame 18 is arrange | positioned in the same direction, but it can also arrange | position to a reverse direction alternately, or can also arrange several site | parts in group form.

  The frame 18 can be cut out and processed from the plate-like body 44 by an appropriate method such as pressing, cutting out by ejecting fluid such as a water jet, or cutting out using a cutting tool such as an end mill. When each frame 18 is processed from the plate-like body 44, it is preferable to process the through hole 14a of the fishing line guide portion 14 and the recess 16b of the support leg portion 16 simultaneously. If necessary, after the frame 18 is cut out, the through holes 14a, the recesses 16b, and the like may be processed.

  The cut frame 18 is processed in detail as necessary. For example, the back surface 22 of the fixed portion 20 is formed in a curved shape so that it can be easily placed on the outer surface of the soot tube 8, and the free end side corners are polished to make the free end side surface 24 curved. It is preferable to make the shape easy to wind or thread.

  After the necessary detailed processing is completed, burrs on the surface of the frame 18 are removed by barrel polishing, and finish polishing is performed so that gloss is obtained on the surface. The degree of this polishing is adjusted according to the characteristics of the fishing line guide 10 such as the size, shape and material, and an abrasive is used if necessary. In particular, the gloss of the polished surface can be further improved by forming the reinforcing fiber to be exposed on a part of the surface of the frame 18 and leaving a part of the matrix resin.

  Next, a film is formed on the whole or a part of the frame as necessary. For example, in order to improve the appearance by providing decoration and protect the frame 18, it may be painted, or metal or ceramics can be deposited.

  In principle, the fixing portion 20 does not need to be subjected to a decorative surface treatment, but in order to improve or stabilize the fixing strength with the tub tube 8, a resin layer softer than the matrix resin of the laminated molding material 30 is provided on the back surface. The coating 22 may be coated, or a paint mixed with particles may be applied to the back surface 22 or roughened by forming irregularities. Furthermore, a film having a high anti-slip effect can be formed on the back surface 22 of the fixed portion 20.

  On the contrary, the reinforcing fiber of the laminated molding material 30 may be exposed on the back surface 22 of the fixing portion 20, and the back surface 22 on which the reinforcing fiber is exposed may be placed and fixed on the soot tube 8.

  The guide ring 12 is attached to the through hole 14a of the frame 18 thus formed. The guide ring 12 can be formed of an appropriate hard material such as ceramic, and the guide ring 12 can be attached to the through hole 14a using an appropriate method such as press-fitting, adhesion, curling, or the like.

  The guide ring 12 is preferably fixed to the frame 18 after the surface treatment, but barreling may be performed after the guide ring 18 is fixed.

  The frame 18 thus formed is not limited to a plate-like shape having the same thickness, and the thickness, the amount of reinforcing fibers, or the tensile elastic modulus can be changed or adjusted depending on the part. The thickness, the amount of reinforcing fibers, or the tensile elastic modulus can be adjusted by variously changing the laminated thickness or the fiber reinforced prepreg to be laminated when the plate-like body 44 is formed.

  In particular, the bending portion 26 in the frame 18 is formed by forming the reinforcing fiber amount less than the bending portion 26 or increasing the proportion of the low elastic modulus reinforcing fiber over the majority of the entire length of the fixed portion 20. 28, the overall strength and durability of the fishing line guide 10 can be improved, and the strength, stabilization and deflection balance of the fishing rod to which the fishing line guide 10 is attached can be improved.

  As shown in FIG. 6, the bent portion 26 on the fixed portion 20 side has a radius of an inner curved surface 26 a that forms an angle smaller than 180 degrees between the support leg portion 16 and the fixed portion 20, and is more than 180 degrees. It is formed to be larger than the radius of the outer curved surface 26b forming a large angle, and the thickness t1 of the bent portion 26 is formed to be thicker than the thickness t2 at the intermediate position in the length direction of the fixed portion.

  As a result, the inner curved surface 26 a is curved more gently than the outer curved surface 26 b, the thickness of this portion increases, and the bent portion 26 is more relative to the support leg portion 16 and the fixed portion 22 in the frame 18. Strength can be improved. Therefore, the entire frame 18 is thinned, and the overall strength and durability of the fishing line guide 10 can be improved. The strength, stabilization and deflection balance of the fishing rod to which the fishing line guide 10 is attached can be improved.

  According to the fishing guide 10 formed in this way, the frame 18 is formed of the laminated molding material 30 formed by laminating fiber reinforced prepregs in which reinforcing fibers are impregnated with synthetic resin, thereby reducing the weight of the fishing line guide 10. The strength can be improved and stabilized, and the balance can be improved and the performance can be improved without impairing the flexibility of the fishing rod.

  If necessary, only the fixing portion 20 may be formed of such a laminated molding material 30. In this case, the same advantage can be obtained.

  The wall thickness t2 of the fixing portion 20 may be gradually or gradually decreased from the bent portion 26 toward the free side end portion, thereby adjusting the arrangement of the reinforcing fibers in the cross direction and adjusting the wall thickness t22. Thus, the flexibility of the fishing rod can be improved, and the strength and stability of the fishing line guide 10 can be improved. Although this thickness t2 depends on the type and size of the fishing line guide 10, it is preferably larger than 1.0 mm and not larger than 2.5 mm (or not larger than 2.0 mm).

  FIG. 7 shows a state where the fishing guide 10 thus formed is fixed to the rod 8.

  The fishing guide 10 is placed on the outer surface of the rod tube 8 in a state where the longitudinal direction of the fixing portion 20 is along the axial length direction of the rod tube 8, and is fixed by a bobbin portion (not shown).

  When the back surface 22 of the fixing portion 20 is coated with a resin layer softer than the matrix resin of the laminated molding material 30, the fishing line is placed on the outer surface of the rod tube 8 through this resin layer and fixed to the rod tube 8. While improving the flexibility of the fishing rod with the guide attached, the rod can be protected and the performance of the fishing rod can be improved.

  Further, when the back surface 22 having a roughened surface and formed with a high anti-slip effect is placed on the outer surface of the rod tube 8, the fixing force by the bobbin is increased and the fishing line guide 10 can be reliably held. .

  On the other hand, the back surface 22 from which the reinforcing fibers of the laminated molding material 30 are exposed may be placed and fixed on the outer surface of the rod 8, and in this case, fish transmission from the fishing guide to the rod is possible. A drop can be prevented and the performance of a fishing rod can be improved. Further, the reinforcing fiber of the soot tube 8 can be exposed to the outer surface, and the fixing portion 20 can be fixed to the soot tube 8 by contacting the back surface 22 of the fixing portion 20 to this portion. When the 30 reinforcing fibers and the reinforcing fibers of the tub tube 8 are in direct contact with each other, it is possible to increase the effect of transmitting fish faith.

  In any case, the reinforcing fibers forming the fiber reinforced resin layers 34 and 36 and the woven fabric layer 38 in the crossing direction are fixed with respect to the axial length direction of the soot tube 8. Since the reinforcing fibers are arranged in the direction and are formed of more than half (1/2 or more) of the entire reinforcing fiber forming the fixing portion 20, suitable flexibility in the longitudinal direction of the fixing portion 20 is obtained, and the soot tube 8 When attached to the tube, it is possible to improve the bending balance of the soot tube 8, alleviate the stress concentration, and improve the strength.

  In particular, such a fishing guide 10 is formed of a reinforcing fiber having a small tensile elastic modulus of the reinforcing fiber of the laminated molded material 30 of the fixed portion 20 with respect to the reinforcing fiber in the axial direction of the anchor tube 8. It is preferable to form it thicker than the wall thickness t2 in the center part in the longitudinal direction of the fixed portion 20 rather than the wall thickness t2. In this case, it is possible to prevent the bending characteristics from being lowered at the portion where the fishing line guide 10 is attached, improve the bending balance over the entire length of the rod 8 and improve the strength and stability of the fishing guide.

  When the synthetic resin content (RC: wt%) of the frame 18 (particularly the fixed portion 20) of the fishing guide 10 is compared with the synthetic resin content of the fiber layer in the axial length direction of the rod 8 by weight. , Preferably 10 wt% or more. Furthermore, it is good to make it high in the range of 15 wt% or more and 35 wt% or less. Thereby, the balance between the rod 8 and the frame 18 can be achieved, and the bending balance of the fishing rod can be improved and the strength and stability of the fishing guide 10 can be improved.

As the distance from the fishing reel increases, the size of the fishing line guide 14 and the guide ring 12 decreases, and the distance between the axis C of the rod 8 and the central axis O of the guide ring 12 also decreases.
