Hereinafter, embodiments of a fishing line guide and a method for manufacturing the same according to the present invention will be described with reference to the drawings.
First, a first embodiment of a fishing line guide according to the present invention will be described with reference to FIGS. In these drawings, FIG. 1 is a perspective view of a fishing line guide, FIG. 2 is a longitudinal sectional view of the fishing line guide, and FIG. 3 is a sectional view taken along line AA of FIG. The arrow D direction in FIGS. 1 and 2 coincides with the axial direction of the fishing rod when the fishing line guide is attached to the fishing rod, the front fixing portion is the tip side, and the rear fixing portion is It is attached so as to be on the Marshal side. Hereinafter, the front side (front side) means the tip side, and the rear side (rear side) means the base end side (margin 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 a synthetic resin are laminated in the front-rear direction ( The configuration of the prepreg, the lamination mode, and the detailed manufacturing method of the frame will be described later.

  The frame 3 is composed of a front-side fiber reinforced resin layer 5 and a rear-side fiber reinforced resin layer 6, and each fiber-reinforced resin layer is formed by laminating a plurality of prepregs as described later. A plurality of fiber reinforced resin layers formed for each prepreg are further laminated and integrated by press molding with a mold. In this case, the front-side fiber reinforced resin layer 5 and the rear-side fiber reinforced resin layer 6 have a width in the left-right direction rather than the thickness in the axial direction (arrow D direction; front-rear direction in FIG. 1) of the contact portion 8 described later. Is formed in a large plate shape.

  In the present embodiment, the front-side fiber reinforced resin layer 5 has a substantially circular contact portion 8a on the upper side and extends in a direction perpendicular to the D direction, and its lower end is substantially perpendicular to the front side. Are bent to form a fishing rod fixing portion 5a. Furthermore, the fiber reinforced resin layer 6 on the rear side has a substantially circular contact portion 8b on the upper side and extends in a direction orthogonal to the D direction, and the fiber reinforced resin layer 5 on the front side in the middle region. The lower end is bent toward the base end side to form a fishing rod fixing portion 6a.

  For this reason, the fishing line guide of the present embodiment has a state in which the upper region (the contact portions 8a and 8b) which are a part of the front fiber reinforced resin layer 5 and the rear fiber reinforced resin layer 6 face each other. The contact portions 8a and 8b form a holding portion H, and a guide ring 9 through which a fishing line is inserted is provided. Further, the fishing rod fixing portions 5a and 6a are respectively connected to the front-side fiber reinforced resin layer 5 and the rear-side fiber reinforced resin layer 6, more specifically, connecting portions (support leg portions) integrated with the contact portions 8a and 8b. ) It is bent below 5b and 6b, and a predetermined distance is maintained between the guide ring 9 and the outer periphery of the fishing rod by the connecting portions 5b and 6b.

  In the present embodiment, openings (through holes) 5c and 6c for holding the guide ring 9 are formed in the contact portions 8a and 8b, respectively. This opening is formed by cutting or the like after being integrated in a state where the upper regions of the front-side fiber reinforced resin layer 5 and the rear-side fiber reinforced resin layer 6 face each other.

  The front and rear fishing rod fixing portions 5a and 6a are portions (also referred to as feet) that are fixed to the surface of the fishing rod, and are a plate-like piece extending in the front-rear direction of the fishing line guide, and a contact surface on the back side thereof. In a state where 5d and 6d are placed on the surface of the fishing rod in accordance with the longitudinal direction of the fishing rod, they are fixed by, for example, winding a thread and then applying an adhesive to the outside thereof. In addition, about the fixing | fixed part 5a, 6a, various shapes can be taken.

  The openings 5c and 6c formed in the contact portions 8a and 8b have the same shape and have a substantially circular outer shape as a whole. The guide ring 9 to be inserted into the opening is configured in a ring shape, and is formed of a member having a small sliding resistance at the fishing line guide surface 9a which is the inner peripheral surface thereof, for example, titanium, aluminum, SUS, ceramics or the like. ing. The guide ring 9 is fitted and fixed to the openings 5c and 6c formed in the contact portions 8a and 8b after the frame 3 is integrally formed by the prepreg.

  Moreover, it is preferable to form at least one or more bent portions in the front-side fiber reinforced resin layer 5 and the rear-side fiber reinforced resin layer 6. In the present embodiment, the fiber-reinforced resin layer 5 on the front side is bent at a boundary portion between the fishing rod fixing portion 5a and the connecting portion 5b more gently than the first bent portion 5e and the first bent portion. Two bent portions 5f are formed, and the fiber reinforced resin layer 6 on the rear side has first portions on both sides of the connecting portion 6b at the boundary portion with the fishing rod fixing portion 6a and at the boundary portion with the contact portion 8, respectively. A bent portion 6e and a second bent portion 6f that is bent more gently than the first bent portion are formed. In this case, either one of the first bent portions 5e or 6e becomes the bent portion having the steepest bending angle in the frame 3.

  When forming the bent portion as described above in the frame 3, the second bent portions 5f and 6f that are gently bent are formed, so that the bending angle of the frame as a whole is set stepwise. Thus, the strength can be improved by dispersing the stress concentration. In particular, if a plurality of bent portions are formed on the frame 3, a bent portion formed in the vicinity of the boundary between the fishing rod fixing portions 5a, 6a and the connecting portions 5b, 6b (the first bent portion in the figure). The tangent lines between the bent portions formed on the contact portion 8 side (corresponding to the second bent portions 5f and 6f in the drawing) than the portions 5e and 6e) are before and after the bent portions. It is preferable to set a small (intersecting angle).

In this way, by setting the bending angle of the bent portion on the contact portion 8a, 8b side to be small, the stress concentration in the portion where the load becomes large can be reduced, such as when a fishing line is applied, and the strength can be reduced. Stabilization can be achieved.
Moreover, the connection parts (support leg parts) 5b and 6b should just protrude slightly from the contact parts 8a and 8b (holding part H).

  As for the connecting portions 5b and 6b described above, the two bent portions are formed in a straight line as shown in the figure, but the two bent portions are formed in a curved shape having a predetermined curved surface. Alternatively, the entire support leg portion may be formed of a curved surface.

  The bent portions 5e, 5f and 6e, 6f formed in the frame 3 as described above are regions that are easily damaged due to stress concentration. However, a manufacturing method and a prepreg configuration as described later are used. Thus, the specific strength and specific rigidity are improved. Note that a reinforcing layer may be provided at the bent portion so that damage is not easily caused even when a load is applied by a fishing line. Here, the reinforcing layer enhances the bending rigidity in the front-rear direction of the frame 3 when the fishing line guide is attached to the fishing rod, and reinforces the bending angle when the bent portion is bent by a load. Any of the prepregs of the plurality of prepregs constituting the laminated fiber reinforced resin layer may be configured to include a reinforced fiber extending along the direction rising from the fishing rod.

  Specifically, the plurality of prepregs, for example, as shown in FIG. 3, have an axial length direction fiber resin layer 21 in which reinforcing fibers are aligned along the direction rising from the fishing rod (the axial length direction of the fishing rod), It has oblique fiber resin layers 22a and 22b in which reinforcing fibers are aligned in a crossing direction having a predetermined angle with respect to the axial direction of the fishing rod, and a woven fabric layer 23 in which the reinforcing fibers are knitted. These fibers of the fiber reinforced resin continuously extend from the fishing rod fixing portion 5a to the contact portion 8. In addition, in FIG. 3, although the laminated structure (laminated material 6A) of the prepreg of the fiber reinforced resin layer 6 of the back side is shown, the fiber reinforced resin layer 5 (laminated material 5A) of the front side is also made into the same laminated structure. The

  In this embodiment, the axial length direction fiber resin layer is formed by a prepreg in which reinforcing fibers are aligned in the axial length direction in a neutral axis area (in FIG. 3, the neutral axis is indicated by X) which is an intermediate position of the thickness of the frame 3. 21 is disposed, and the reinforcing fiber is drawn 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 the aligned prepregs, and further woven by the prepregs in which the reinforcing fibers are knitted on the outermost layer (the entire surface on both sides may be partially outermost). A cloth layer 23 is provided. 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.

  In this way, when forming a fishing line guide made of fiber reinforced resin, when the frame itself is viewed from the front or plan, a prepreg is selected and laminated so that the reinforcing fibers are oriented in at least three directions. Is preferred. That is, by setting the direction of the reinforcing fibers to three or more directions, it is possible to form a fishing line guide that is efficient, lightweight, and excellent in strength. Further, as described above, by providing the axial length direction fiber resin layer 21 in the intermediate layer region of the frame 3, a bending force acts on the frame 3 by the tension of the fishing line along the axial length direction. Even so, it is possible to efficiently increase the specific rigidity in that direction while reducing the weight.

  Furthermore, it is preferable that the woven fabric layer 23 is disposed on the outermost layer of the frame 3 as in the above-described prepreg arrangement configuration. 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.

  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 5e, 5f and 6e, 6f can be relatively strengthened, and a fishing line guide that is lightweight and excellent in strength balance can be obtained. In addition, the mesh width of the woven fabric layer 23 is preferably smaller than the minimum width in the areas of the fishing rod fixing portions 5a and 6a and the contact portions 8a and 8b.

  Next, a method for forming the frame 3 having the above configuration will be described with reference to FIGS.

  The frame 3 includes a plurality of prepregs (laminates) 5A constituting a front-side fiber reinforced resin layer having a laminated structure as shown in FIG. 3, and a plurality of sheets constituting a rear-side fiber reinforced resin layer. It is formed of a prepreg (laminated material) 6A. In this case, as described above, the prepreg constituting each layer 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. It has a configuration in which a curable resin (for example, epoxy resin) or a thermoplastic resin (for example, nylon) is impregnated as a matrix resin. In addition, although the flame | frame 3 is comprised by the some fiber reinforced resin layer, it may contain the reinforcement layer so that the above-mentioned bending part may be reinforced.

  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 superimposed (number of layers) and the configuration of individual prepregs are not particularly limited. As described above, the bent portions 5e, 5f and 6e, 6f are formed on the frame 3 and used. At this time, the type of prepreg and the conditions for overlapping are arbitrarily adjusted in consideration of the load applied to the frame 3, the characteristics of the fishing rod to be mounted, the mounting portion, and the like.

  A plurality of laminated materials 5A and 6A laminated in this way are set in a mold 50 as shown in FIG. The mold 50 according to the present embodiment is configured by an upper mold 51 and a lower mold 52 that are divided vertically, and the upper mold 51 is further configured by left and right molds 51a and 51b that are divided right and left. ing. In this case, the lower mold 52 is formed with a ridge 52a having a generally triangular shape in cross section, which has a gently curved inclined surface on one end surface and a vertical surface on the other end surface, and the top 52b of the ridge 52a is a boundary. Thus, the left and right molds 51a, 51b are configured to open in the left-right direction.

  The method for setting the laminates 5A and 6A to the mold is not particularly limited. For example, the laminates 5A and 6A are set so that the upper region from the top 52b of the peak portion 52a is in contact with each other (one of the two laminates). The two laminated materials are set as they are along the ridges 52a of the lower mold 52 below (there are portions where a fishing rod fixing part is not formed). It becomes a contact part). In this case, the laminated materials 5A and 6A may be set 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 fiber can be reduced, and it can be accurately set at a predetermined position. Further, a cavity 55 is formed between the left and right molds 51a, 51b of the upper mold 51 and the lower mold 52 in accordance with the position where the laminated materials 5A, 6A are set. The mold is coated.

  The hollow portion 55 corresponds to the thickness of the frame 3, and when the laminated material 5A, 6A is placed on the lower mold 52, the positions corresponding to the bent portions 5e, 5f and 6e, 6f described above. In addition, bend forming recesses 52d and 52e are formed. The right mold 51b is formed with a bend forming protrusion 51d corresponding to the bend forming recess 52d, and the left mold 51a is formed with a bend forming protrusion 51e corresponding to the bend forming recess 52e. Further, the hollow portion 55 is formed between the lower mold 52 and the left and right molds 51a and 51b so that the fishing rod fixing portions 5a and 6a are formed.

  In addition, about the above-mentioned metal mold | die, only an example was shown, About the direction of mold division, it can be set as arbitrary forms, such as making it into the left-right direction or an inclination direction.

  As described above, after the laminated materials 5A and 6A are set at predetermined positions of the lower mold 52, the laminated material 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. This plate-like body 30 is in a state in which the front-side fiber reinforced resin layer and the rear-side fiber reinforced resin layer are integrated in the region of the joint portions 8a and 8b. In FIG. A portion representing the central portion of the fiber reinforced resin layer is indicated by a two-dot chain line.

  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 part, voids of the bent parts 5e, 5f and 6e, 6f of the molded frame can be prevented, and the strength can be improved and stabilized. . In addition, the bent portions 5e, 5f and 6e, 6f of the molded frame 3 can be made to have a higher fiber ratio than the front and rear regions (fixed portions and supporting leg portions), and thus are easily damaged. The bent portion can be strengthened. Or it is preferable to make fiber ratio higher than the area | region before and behind about the bending parts 5e and 5f and 6e and 6f. 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.

  Next, the frame 3 is cut out from the plate-like body 30 so as to have a predetermined shape (the unnecessary portion is deleted (destroyed) from the plate-like body 30 and the frame 3 is taken out (leaves)). 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 that the basic outer shape of the frame 3, that is, the contact portions 8a and 8b having the openings 5c and 6c, the connecting portions 5b and 6b, the fishing rod fixing portions 5a and 6a, and the like are simultaneously formed. These may be formed in separate steps. 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.) ), A curved shape may be included, or an opening may be formed to reduce the weight.

  Next, detailed processing is performed as necessary. For example, the detailed processing is performed by, for example, forming the shape of the fishing rod fixing portions 5a and 6a into a curved shape so that the fishing rod fixing portions 5a and 6a can be easily placed on the fishing rod, Is applicable.

  Next, the surface treatment of the frame 3 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, the polishing time, etc. according to the size, shape, material characteristics, etc. of the fishing line guide 1. By performing such barrel processing, the frame 3 can be polished without cutting the reinforcing fiber, the strength can be stabilized, and a fishing line guide having an excellent appearance can be obtained.

  In addition, when performing such a grinding | polishing process, it is preferable to grind | polish so that a part of reinforcing fiber may be exposed to the surface of the flame | frame 3, and a matrix resin may remain partially. By doing so, it becomes possible to further improve the gloss of the polished surface. Further, the side surface of the frame 3 is polished so that the plurality of fiber reinforced resin layers are flush with each other.

  Next, a film is formed on all or a part of the frame 3 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 9 is attached to the openings 5c and 6c of the frame formed as described above. As a method for attaching the guide ring 9, any fixing method such as press-fitting, adhesion, curling, or the like can be adopted.

  According to the fishing line guide 1 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. Is 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. Furthermore, since the fishing rod fixing portions 5a and 6a are provided on both the front side and the rear side of the contact portions 8a and 8b, it is possible to stably hold the fishing rod and guide the fishing line stably.

  In the present embodiment, the fiber reinforced resin layer 5 on the front side and the fiber reinforced resin layer 6 on the rear side are formed as separate bodies with substantially the same shape, and the fiber reinforced resin layers 5 and 6 are, for example, It is integrally formed as a plate-shaped body in advance by a mold 60 as shown in FIG. In this case, the laminated material 5A (6A) constituting each fiber reinforced resin layer can have the same structure as in FIG. 3, and each laminated material 5A (6A) is set at a predetermined position of the lower mold 62. Then, by pressing with the upper mold 61, it is possible to form the front frame body 5F and the rear frame body 6F as shown in FIGS.

  In each frame body 5F, 6F formed as a plate-like body, the regions serving as contact portions in the first embodiment described above constitute joint portions 5H, 6H (holding portions H for holding guide rings), respectively. These portions are face to face and joined (contacted) with an adhesive or the like. In this case, as shown in FIG. 7, openings (through holes) 5C and 6C into which the guide rings 9 are fitted are formed in the frame bodies 5F and 6F, respectively, as shown in FIG. For this reason, the joining state of both frame bodies is maintained by joining the joint portions 5H and 6H of both frame bodies 5F and 6F with an adhesive or the like and fitting the guide ring 9 into the opening. . In addition, joining of both frame bodies may be integrated by heating, and the opening may be formed after joining both frame bodies 5F and 6F.

  According to the fishing line guide having such a configuration, the same effects as those of the above-described embodiment can be obtained, and the front and rear frame bodies can be formed in the same shape, thereby simplifying the production. Is possible. Further, the respective frame bodies 5F and 6F can be used as they are as one-foot guides as long as they are not joined at the joining portions 5H and 6H.

  Moreover, although the fishing line guide 1 demonstrated the structure fixed to a fishing rod by a thread stop etc., for example, you may be comprised as a floating guide slidably fitted with respect to a 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. Further, in the above-described embodiment, the fishing rod fixing portion is formed via the connecting portion on the front side fiber reinforced resin layer and the rear side fiber reinforced resin layer. The structure which forms a fishing rod fixing | fixed part from a contact part (joint part) may be sufficient.

  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.

  Further, the frame may be laminated such that the fiber reinforced resin layers on both sides with respect to the center of the fiber reinforced resin layer are symmetrical with respect to each other toward the outer layer. In addition, the frame has oblique fiber reinforcement in which reinforcing fibers are inclined in directions opposite to each other with respect to the longitudinal axis of the frame (the extending direction of the frame) on one side and the other side with respect to the center of the fiber reinforced resin layer. A resin layer may be provided. Further, the frame is provided with reinforcing fibers in the axial length direction (extending direction of the frame) in a neutral shaft region that is an intermediate position in the thickness direction (front-rear direction) of the frame, and outside the neutral shaft region. The reinforcing fibers may be arranged in a direction intersecting the axial length direction. Further, the side surface of the frame may be formed with a plurality of fiber reinforced resin layers appearing on the side surface.
