The direction of arrow D in FIGS. 3 and 3 coincides with the axial length 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 the original. It is attached to be on the heel 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 of fiber reinforced resin layers formed by impregnating reinforcing fibers with synthetic resin. Here, the “fiber reinforced resin layer” is a laminate in which sheet-like prepregs are stacked and laminated, or tape-like or thread-like ones are stacked, bundled, or tape, thread-like or sheet-like prepregs are combined. The thickness, width, cross-sectional shape, etc. of the layer can be arbitrarily laminated according to the shape of each part of the fishing line guide. Such a frame may be obtained by cutting a fiber reinforced prepreg formed into a plate shape into a frame shape as described later, or a fiber reinforced resin is disposed in a space for forming a fishing line guide of a mold and a fishing line guide. May be molded (in this case, cutting is not necessary) and can be produced by any method. However, in each of the following embodiments, for convenience, the frame 3 is formed by 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 structure 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. Each fiber-reinforced resin layer is formed by laminating a plurality of prepregs as will be 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 fiber reinforced resin layer 5 on the front side and the fiber reinforced resin layer 6 on the rear side are based on the thickness in the axial direction (arrow D direction; front and rear direction in FIG. 1) of a contact portion 8 (8a, 8b) described later. Is also formed in a plate shape having a large width in the left-right direction.

  In the present embodiment, the front fiber reinforced resin layer 5 is formed as a substantially annular contact portion 8a. Further, the fiber reinforced resin layer 6 on the rear side includes a fiber reinforced resin in a direction substantially perpendicular to the D direction from the contact portion 8b and a contact portion 8b on the upper side in contact with the contact portion 8a. A pair of supporting leg portions 6b extending obliquely so as to be separated from the layer 5 and a fishing rod fixing portion 6a extending bent backward toward the rear side so as to be integrated at the lower ends of the supporting leg portions 6b are formed. doing.

  In the fishing line guide according to the present embodiment, the abutting portion 8a constituting the front-side fiber reinforced resin layer 5 and the abutting portion 8b in the upper region, which is a part of the rear-side 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 the fishing line is inserted is provided. Further, in this case, each support leg portion 6b is in a state of protruding from the rear surface h of the holding portion H at a substantially intermediate position in the vertical direction of the holding portion H with the same width W as the width W of the rear surface h. That is, in this embodiment, the thickness W of the holding part H in the left-right direction is larger than the thickness of the width in the front-rear direction, and under that condition, the support leg part 6b has at least the front surface or A branch portion 6g (a portion branched from the holding portion) protruding from the rear surface (rear surface in the present embodiment) is formed. That is, the branch portion 6g has a width in the left-right direction and a width in the front-rear direction of the holding portion H. Are formed from the side having the larger dimension (the width in the left-right direction of the holding part having a large thickness). As described above, when the branching portion protrudes from the front surface (or the rear surface (second embodiment described later)) of the holding portion, the direction of the reinforcing fiber can be stabilized, and the strength can be improved and stabilized. It is possible to prevent the left and right widths from increasing, and it is possible to reduce the size and weight. Furthermore, catching of the fishing line can be prevented. Further, when the branching portion of the support leg portion is formed from at least the larger dimension of the thickness of the holding portion in the horizontal direction and the width in the front-rear direction, the integrated range of the holding portion and the support leg portion is formed. Can be expanded, and strength can be improved, miniaturized, and lightened. In this embodiment, each support leg 6b protrudes from the rear surface h of the holding part H with the same width W as the width W of the rear face h. However, the width of the support leg 6b is the portion of the branching part 6g. The width from the position past the branch portion to the fixed portion 6a is formed wider or smaller than the branch portion, or the direction is adjusted. It is possible.

  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. The openings 5c and 6c are 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 fishing rod fixing portion 6a is a portion (also referred to as a foot portion) that is fixed to the surface of the fishing rod (rod tube), and is a plate-like piece that extends in the rearward direction of the fishing line guide. In a state where it is placed on the surface according to the longitudinal direction of the fishing rod, it is fixed by, for example, applying an adhesive to the outside after winding the thread. In addition, about the fixing | fixed part 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 6 on the rear side, the boundary portion with the fishing rod fixing portion 6a on both sides of the support leg portion 6b, and the boundary portion with the contact portion 8b (the protruding portion) are respectively provided. A first bent portion 6e and a second bent portion 6f that is bent more gently than the first bent portion are formed.

  When the bent portion as described above is formed in the frame 3, by forming the second bent portion 6f that gently bends, it is possible to set the bending angle by bending the entire frame 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 at or near the boundary portion between the fishing rod fixing portion 6a and the supporting leg portion 6b (the first bent portion 6e in the figure corresponds). Is set smaller than the bending angle of the bent portion (the second bent portion 6f in the figure corresponds) in the contact portion 8b side (the angle at which the tangent lines intersect before and after the bent portion). It is preferable.

  In this way, by setting the bending angle of the bent portion on the abutting portion 8b side to be small, it is possible to alleviate stress concentration in a portion where the load becomes large, such as when a fishing line is applied, and to stabilize the strength. Can be planned.

  In addition, about the above-mentioned support leg part 6b, between two bending parts was formed linearly as shown in the figure, but between two bending parts, even if it forms in the curved shape which has a predetermined curved surface Alternatively, the entire support leg portion may be formed of a curved surface.

  The bent portions 6e and 6f formed on the frame 3 as described above are regions that are easily damaged due to stress concentration. However, by using the manufacturing method and the configuration of the prepreg described later, the specific strength is obtained. In addition, the specific rigidity is 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, for example, as shown in FIG. 5, the plurality of prepregs include an axial length direction fiber resin layer 21 in which reinforcing fibers are aligned along a direction rising from a fishing rod (which is 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. The fibers (fiber reinforced resin layer) of these fiber reinforced resins are continuous from at least a part of the holding part H to at least a part of the support leg part 6b. In particular, in this embodiment, as clearly shown in FIG. 4, the fiber (fiber reinforced resin layer) of the fiber reinforced resin 6 on the rear side continues (over the entire length) from the fishing rod fixing portion 6a to the contact portion 8b. On the other hand, the fiber reinforced resin layer 5 on the front side also extends continuously over the entire length. 5 shows the prepreg laminated structure (laminate 6A) of the fiber reinforced resin layer 6 on the rear side, the fiber reinforced resin layer 5 (laminate 5A) on the front side has a similar laminated structure. The For simplicity, the seven layers in FIG. 5 are depicted as four layers in FIGS.

  In this embodiment, an 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. 5, 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. Also, the bent portions 6e and 6f can be relatively strengthened, and a fishing line guide that is lightweight and has an excellent strength balance can be obtained. The mesh width of the woven fabric layer 23 is preferably smaller than the minimum width in the region of the fishing rod fixing portion 6a and the contact portions 8a and 8b.

  Next, a method for forming the frame 3 having the above-described 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. 5, 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. However, as described above, the bent portions 6e and 6f 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.

  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 composed of an upper mold 51 and a lower mold (bottom mold) 52 that are divided vertically, and the upper mold 51 is further divided into a left and right mold (front). (Part type and rear type) 51a, 51b. 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 mold 50 is a mold that can open or close at least a three-way mold (bottom mold 52, front mold 51a, rear mold 51b) in a molded state. A pin or a piece may be used, and any structure may be used as long as a predetermined portion of the mold 50 can be opened and closed in three or more directions. The movement and structure of the frames and pins for opening and closing in three directions or more can be arbitrarily set.

  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 the lower mold 52 is bent at positions corresponding to the bent portions 6e and 6f when the laminated materials 5A and 6A are placed. A recess 52e is formed. Further, the left mold 51a is formed with a bend forming convex portion 51e corresponding to the bend forming concave portion 52e. Further, the hollow portion 55 is formed between the lower die 52 and the left die 51a so that the fishing rod fixing portion 6a is 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 formed as shown in FIG. 7 and 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. 1, the part showing the center part of both such fiber reinforced resin layers is shown with the dashed-two dotted 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 portion, voids in the bent portions 6e and 6f of the molded frame can be prevented, and the strength can be improved and stabilized. In addition, the bent portions 6e and 6f 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. Alternatively, it is preferable that the fiber ratio of the bent portions 6e and 6f is higher than that of the front and rear regions. For example, as described in the above-described process, it is possible to increase the fiber ratio of the bent portion by increasing the pressing force in the bent portion region during heat forming, and the fiber ratio of the bent portion can be increased. By doing so, it is possible to obtain a fishing line guide that is not easily damaged even when the frame is bent due to the load acting.

  Next, the frame 3 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 by a liquid (water jet or the like), or cut out by a blade (end mill or the like), Alternatively, by adopting an arbitrary method such as cutout that deletes or destroys unnecessary portions, a plurality of frames 3 can be cut out from a single plate-like body 30 as shown in FIG. A strong fishing line guide can be efficiently manufactured.

  During this processing, it is preferable to simultaneously form the basic outer shape of the frame 3, that is, the contact portions 8a and 8b having the openings 5c and 6c, the support leg portion 6b and the fishing rod fixing portion 6a. You may form by the process. 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 may include forming the shape of the fishing rod fixing portion 6a into a curved surface so that it can be easily placed on the fishing rod, or polishing the end of the fixing portion so that it can be easily wound and threaded. To do.

  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, it is possible to polish the frame 3 without damaging the reinforcing fibers, and it is possible to stabilize the strength and to make a fishing line guide with an excellent appearance.

  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. Further, the fiber reinforced resin layer is continuous from at least a part of the holding part to at least a part of the support leg part (in this embodiment, the fiber (fiber reinforced resin layer) of the fiber reinforced resin 6 on the rear side is provided. The fishing line guide 1 is high because it extends continuously (over the entire length) from the fishing rod fixing portion 5a to the abutting portion 8b, while the front-side fiber reinforced resin layer 5 also extends continuously over the entire length). Strength can be realized.

  8 and 9 show a modification of the above-described first embodiment. In this modification, a fiber reinforced resin layer (at least two fiber reinforced prepregs) continuous over the entire length between the support leg portion 6b and the contact portion 8a (front side holding portion) constituting the fiber reinforced resin layer 5 on the front side. A reinforcing piece 100 (in particular, see FIG. 9) is provided (for example, a fiber reinforced resin layer formed by laminating one axial length fiber resin layer and the other oblique fiber resin layer). This reinforcing piece 100 prevents tearing between the contact portion 8 a and the layer 6.

  Therefore, in this modification, when the laminated material 5A, 6A is set in the mold 50 when the frame 3 is formed, the reinforcing piece 100 is attached to the support leg portion 6b and the contact portion 8a as shown in FIG. Arrange between.

  11 to 14 show a fishing line guide according to a second embodiment of the present invention. As shown in the drawing, the fishing line guide 1A of the present embodiment also includes a frame 3 formed of a laminated material having a plurality of fiber reinforced resin layers in which fiber reinforced prepregs in which reinforcing fibers are impregnated with synthetic resin are laminated in the front-rear direction. Yes.

  Specifically, the frame 3 includes a front-side fiber reinforced resin layer 5 and a rear-side fiber reinforced resin layer 6, and the front-side fiber reinforced resin layer 5 has a substantially semicircular ring shape on the upper side. The abutment part 8a, a support leg part (front side support leg part) 5b extending substantially vertically downward from the contact part 8a in a direction substantially perpendicular to the D direction, and a lower end of the support leg part 5b toward the front side. A fishing rod fixing portion 5a that is bent and extends is formed. On the other hand, the fiber reinforced resin layer 6 on the rear side includes, as in the first embodiment, a contact portion 8b that contacts the contact portion 8a, a support leg portion (rear side support leg portion) 6b, and a fishing rod fixing portion 6a. Formed (that is, unlike the first embodiment, the supporting leg portion protrudes from the front surface and the rear surface of the holding portion via the branching portion. The same applies to the fourth embodiment described later. ). In addition, since the form of the fiber reinforced resin layer 6 on the rear side is the same as that of the first embodiment, the form of the fiber reinforced resin layer 5 on the front side will be described below. Moreover, in this structure, the front side support leg part 5b may be arrange | positioned at the heel side (back side), and the back side support leg part 6b may be arrange | positioned at the heel side (front side), and an attachment direction is not limited.

  The front fishing rod fixing portion 5a is a portion (also referred to as a foot) that is fixed to the surface of the fishing rod, and is a plate-like piece extending in the front-rear direction of the fishing line guide, and the contact surface 5d on the back side is the surface of the fishing rod. For example, after the thread is wound, it is fixed by applying an adhesive on the outside thereof. In addition, about the fixing | fixed part 5a, various shapes can be taken.

  Moreover, it is preferable to form at least one or more bent portions in the front fiber reinforced resin layer 5 as well as the rear fiber reinforced resin layer 6. In this embodiment, the front fiber reinforced resin layer 5 has a first bent portion 5e formed at the boundary portion between the fishing rod fixing portion 5a and the support leg portion 5b. The first bent portion 5e or 6e is the bent portion having the steepest bending angle in the frame 3.

  As described above, regarding the layer 5, when the bent portion as described above is formed in the frame 3, the entire frame is bent by forming the second bent portion 6 f that is gently bent. It is possible to set the bending angle by stepwise, and it is possible to improve the strength by dispersing the stress concentration. In particular, if a plurality of bent portions are formed on the frame 3, a bent portion (the first bent portion in the figure) is formed at or near the boundary portion between the fishing rod fixing portions 5a, 6a and the supporting leg portions 5b, 6b. Tangent lines intersect before and after the bent angle of the bent portion (corresponding to the second bent portion 6f in the figure) formed on the abutting portion 8 side rather than the portions 5e and 6e. The angle is preferably set small.

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

  Further, the fiber reinforced resin layer 5 on the front side of this embodiment also has the same laminated structure as that of the first embodiment (see FIG. 5), and the fiber reinforced resin layer (or the layer is configured). Reinforcing fiber) is continuous from at least a part of the holding part H to at least a part of the support leg part 5b. In particular, in the present embodiment, as clearly shown in FIG. 14, the fiber reinforced resin layer (or the reinforced fiber) of the front fiber reinforced resin 5 extends from the fishing rod fixing portion 5a to the contact portion 8a (full length). Extending continuously).

  Next, a method for forming the frame 3 having the above configuration will be described with reference to FIGS. 15 and 16.

  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. 5, 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 stacked (number of layers) and the configuration of individual prepregs are not particularly limited. However, as described above, the bent portions 5e and 6e, 6f are formed on the frame 3, and the prepreg is used in use. 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, the type of prepreg and conditions for stacking are arbitrarily adjusted.

  A plurality of laminated materials 5A and 6A laminated in this manner are set in a mold 50 as shown in FIG. 15 (in other words, a fiber reinforced resin layer or a reinforced fiber of a fiber reinforced resin frame is attached to a holding portion. Are arranged in a mold 50 having a bottom mold 52, a front mold 51a, and a rear mold 51b so as to be continuous from at least a part of the mold to at least a part of the support leg. Similarly to the first embodiment, the mold 50 according to the present embodiment is composed of an upper mold 51 and a lower mold 52 that are divided vertically, and the upper mold 51 is further divided into left and right. The left and right molds 51a and 51b are configured. 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 hollow portion 55 is located at a position corresponding to the bent portions 5e, 6e, 6f. Bending formation 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 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 5e, 6e, and 6f of the molded frame can be prevented, and strength can be improved and stabilized. Accordingly, the bent portions 5e and 6e, 6f 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 are easily damaged. 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 6e, 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 shown in FIG. 16 so as to have a predetermined shape (unnecessary portions are 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. 16, a plurality of frames 3 can be cut out from a single plate-like body 30, and a lightweight and high-strength fishing line guide can be efficiently manufactured. It becomes possible. The other manufacturing methods are the same as those in the first embodiment.

  As described above, the present embodiment has the same operational effects as the first embodiment, and the fishing rod fixing portions 5a and 6a are provided on both the front side and the rear side of the holding portion H of the guide ring. Therefore, the fishing line can be stably guided.

  17 and 18 show a third embodiment of the present invention. In the present embodiment, in addition to the configuration of the second embodiment, the fiber reinforced resin layer (or reinforcing fiber) constituting the frame 3 is changed from at least a part of the front side support leg part 5b to at least a part of the rear side support leg part 6b. Is continuous. In particular, in this embodiment, the front fiber reinforced resin layer 5 (or reinforcing fiber) and the rear fiber reinforced resin layer 6 (or reinforcing fiber) are integrated and continuous. That is, the fiber reinforced resin layer (fibers constituting the fiber reinforced resin layer) is continuous (over the entire length) from the fiber reinforced resin layer 5 on the front side to the fiber reinforced resin layer 6 on the rear side.

Therefore, in this embodiment, when the frame 3 is formed, as shown in FIG. 18, the long laminated material 120 in which the laminated materials 5A and 6A are integrated is folded at the middle portion in the longitudinal direction. To set the mold 50.
As can be seen from the above, the fiber-reinforced resin layer (or only the reinforcing fibers forming the layer) may be continuous from the holding portion to the support leg portion as shown in the second embodiment described above, or As shown in the third embodiment, it may be continuous from one supporting leg part to the other supporting leg part.

  19 and 20 show a modification of the third embodiment. In this modification, a reinforcing layer (fiber is continuous) between the front support leg 5b and the rear support leg 6b over the entire length (at least two fiber-reinforced prepregs (for example, the inside is an axial length direction fiber resin). A fiber reinforced resin layer) 200 formed by laminating a layer and an oblique fiber resin layer on the outside. In particular, in the present modification, the rear end of the reinforcing layer 200 (two layers on the bottom surface) extends to the rear end of the rear fishing rod fixing portion 6a, and the front end of the reinforcing layer 200 is the front fishing rod fixing portion. It extends to reach the front end of 5a and is reinforced across the boundary between the fiber reinforced resin layer 5 on the front side and the fiber reinforced resin layer 6 on the rear side. The reinforcing layer 200 may be a reinforcing piece having a shorter length as long as it is provided so as to straddle the boundary.

  Therefore, in this modification, when the frame 3 is formed, as shown in FIG. 20, when the long laminated material 120 is set in the mold 50 in a state of being folded back at the middle portion in the longitudinal direction, The long reinforcing layer 200 is also set so as to be overlapped on the inner side of the laminated material 120 in a state of being folded back at the intermediate portion.

  21 to 23 show a fourth embodiment of the present invention. In the present embodiment, the holding portion H is configured by a front contact portion 8a, a rear contact portion 8b, and an intermediate portion 210 sandwiched between the contact portions 8a and 8b. The intermediate portion 210 is formed in an annular shape from the same material as the contact portions 8a and 8b, and the fibers are continuous over the entire length. The rest of the configuration is substantially the same as in the second embodiment (the support leg 5b of the front fiber reinforced resin layer 5 is substantially the same as the support leg 6b of the rear fiber reinforced resin layer 6). Except where configured).

  Therefore, in this embodiment, when the laminated material 5A, 6A is set in the mold 50 when the frame 3 is molded, the intermediate portion 210 is sandwiched between the contact portions 8a, 8b as shown in FIG. Arrange in the state.

  According to the present embodiment, the presence of the intermediate portion 210 increases the holding force for holding the guide ring 9 and can reliably prevent the guide ring 9 from falling off the holding portion H.

  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 1 is constituted by a fiber reinforced prepreg, and the specific strength, specific rigidity, etc. are increased, and in particular, as described above so as not to cause breakage in the bent portion region. It is characterized by using the manufacturing method and the arrangement mode of the prepreg. The prepreg constituting the above-described frame is not limited to the embodiment with respect to the configuration and type of reinforcing fiber, the elastic modulus, the resin impregnation amount, the thickness, and the like, and may be variously modified. Is possible.

  Further, the fishing line guide 1 does not have to be fixed to the fishing rod by a thread stopper or the like. For example, the fishing line guide 1 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.

  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.

  Moreover, in embodiment mentioned above, the support legs 5b and 6b are protrudingly provided from the front surface (1st-4th embodiment) or the rear surface (2nd-4th embodiment) in the up-down direction intermediate position of the holding | maintenance part H. The fiber reinforced resin layer is continuous over the entire length of the support legs 5b and 6b and the holding part H, but the fiber reinforced resin layer is held from the protruding part of the supporting legs 5b and 6b protruding from the holding part H. It may be continuous over the upper side of the part H, or may be continuous from the projecting part of the supporting leg parts 5b, 6b projecting from the holding part H to the lower side of the holding part H. The fiber reinforced resin layer may be continuous from at least a part of the holding part H to at least a part of the support legs 5b and 6b.

  FIG. 25 shows a fifth embodiment of the fishing line guide according to the present invention. As shown in the drawing, the support leg portion of the present embodiment does not project from the rear surface of the holding portion H at a substantially intermediate position in the vertical direction of the holding portion H as in the first and second embodiments. It extends from the top Ha of H. Specifically, the fishing line guide of the present embodiment is positioned as a modification of the second embodiment, and is a laminated material in which fiber reinforced resin layers (for example, prepregs) in which reinforcing fibers are impregnated with synthetic resin are laminated in the front-rear direction. The frame 3 is formed. The fiber reinforced resin layer (or reinforcing fiber) constituting the frame 3 is continuous from at least a part of the front side support leg part 5b to at least a part of the rear side support leg part 6b. In particular, in this embodiment, the front fiber reinforced resin layer 5 (or reinforcing fiber) and the rear fiber reinforced resin layer 6 (or reinforcing fiber) are integrated and continuous. That is, the fiber reinforced resin layer (or the reinforced fibers constituting the layer) is continuous from the front fiber reinforced resin layer 5 to the rear fiber reinforced resin layer 6 (over the entire length). Then, the rear support leg portion 6b starts from the top portion Ha of the holding portion H and overlaps with a considerable portion excluding a part of the lower circular arc portion of the rear surface of the ring-shaped holding portion H ((b in FIG. 25). )), And extends obliquely downward toward the fishing rod fixing portion 6a. Moreover, in this embodiment, the outer surface of the back side support leg part 6b and the outer surface of the holding | maintenance part H are flush. Thereby, the width dimension in the left-right direction of the fishing line guide can be reduced, and entanglement of the fishing line with respect to the fishing line guide can be reduced. On the other hand, the front side support leg part 5b extends from the lower end of the holding part H to the fishing rod fixing part 5a by extending substantially vertically downward and bending in the horizontal direction. In addition, the front side support leg part 5b may extend from the front surface of the holding part H.

  In the present embodiment, the thickness t1 of the rear side support leg 6b is set to be larger than the thickness t2 of the front side support leg 5b. Therefore, the rear-side support leg portion 6b having a large thickness can be referred to as a main leg, and the front-side support leg portion 5b having a small thickness can also be referred to as an auxiliary leg. In this case, the bent portions 5e and 6e of the supporting leg portion can also be made thicker in the main leg and thinner in the auxiliary leg. Such thickness adjustment is possible because the support leg is formed of the fiber reinforced resin layer. When the support leg (plate) is formed by pressing a metal plate as in the prior art, the thickness cannot be adjusted. Further, by relatively changing the thickness of the main leg and the auxiliary leg as in the present embodiment, it becomes possible to reduce the weight and size of the main leg and the auxiliary leg as a whole. In addition, the balance design improves the strength balance.

  Further, in the present embodiment, the rear side support leg portion 6b has a wall thickness dimension t1 larger than its width dimension w1, so that it is possible to reduce the weight and increase the strength, and to change the fishing line for the guide. Can be reduced. In addition, the width dimension w1 of the back side support leg part 6b is set smaller than the width dimension w2 of the fishing rod fixing | fixed part 6a.

  In relation to the technical idea of distinguishing the support legs 5b and 6b from the main legs and the auxiliary legs by the thickness, FIGS. 26 to 28 show the thickness of each part of the frame 3 and the fiber reinforced resin layers ( Or the continuity of the reinforcing fibers) is shown.

  FIG. 26 shows a configuration of a fiber reinforced resin layer similar to that of the second embodiment, that is, the front fulcrum 5b and the rear fulcrum 6b are configured by separate fiber reinforced resin layers 5 and 6, and each fiber reinforced resin is reinforced. The resin layer (or its reinforcing fiber) is continuous from the holding part H to the fixing parts 5a, 6a, and the front side supporting leg part 5b and the rear side supporting leg part 6b as in the third embodiment. A structure in which a configuration in which the reinforcing layer 200 is provided so as to extend along the entire length is shown. In this structure, the thickness T1 of the rear side support leg portion 6b in which the fiber reinforced resin layer 6 and the reinforcing layer 200 are combined; The thickness T2 of the front side support leg portion 5b combining the fiber reinforced resin layer 5 and the reinforcing layer 200 and the thickness T3 of the holding portion H combining the fiber reinforced resin layer 5 and the fiber reinforced resin layer 6 are T3. > T1> T2 (T3 = T2 Is set to a size relationship such that 2). That is, the upper part (holding part) of the fishing line guide is reinforced. However, the dimensional relationship such that T1 = T2 = T3 may be set to improve the balance of the entire guide, or the dimensional relationship such that T3 = T1> T2 may be set, and the rear side supporting leg as the main leg may be set. While improving the intensity | strength of the part 6b, you may improve the flexibility of the front side support leg part 5b as an auxiliary leg.

  FIG. 27 shows a structure in which the reinforcing layer 200 is excluded from the fixing portions 5a and 6a in the structure of FIG. In this structure, the thickness T1 of the rear side support leg 6b that combines the fiber reinforced resin layer 6 and the reinforcing layer 200, and the thickness T2 of the front side support leg 5b that combines the fiber reinforced resin layer 5 and the reinforcing layer 200 are combined. And a thickness T3 of the holding portion H that combines the fiber reinforced resin layer 5 and the fiber reinforced resin layer 6, a thickness T4 of the rear fixing portion 6a, and a thickness T5 of the front fixing portion T1. = T2 = T3> T4 = T5 is set to have a dimensional relationship. According to such a dimensional relationship, it is possible to improve the flexibility of the fixing portions 5a and 6a by thinning the fixing portions 5a and 6a.

  FIG. 28 shows a structure (the same structure as in the second embodiment) in which the reinforcing layer 200 is completely eliminated in the structure of FIG. In this structure, the dimensional relationship is set such that T3> T1 = T2. According to such a dimensional relationship, the weight of the guide can be reduced. In the present configuration, when the fiber reinforced resin layer 5 and the fiber reinforced resin layer 6 are desired to be continuously integrated, the fiber reinforced resin layer 5 and the fiber reinforced resin layer are formed as shown in FIG. It is desirable to form a boundary portion with 6 in a smooth curved shape to prevent an extreme change in fiber direction.

  FIG. 29 shows a sixth embodiment of the fishing line guide according to the present invention. In the present embodiment, unlike the first embodiment, the thickness W1 in the front-rear direction width of the holding portion H is larger than the thickness W in the left-right direction. 6b is formed with a branch portion 6g (a portion branched from the holding portion) protruding from the side surface of the holding portion H (the rear side support leg portion 6b is not from the narrow rear surface of the holding portion H but the holding portion). Extending from a wide range of H). That is, the branching portion 6g is formed so as to protrude from the side with the larger dimension (the width in the front-rear direction of the thicker holding portion) of the thickness of the holding portion H in the left-right direction and the front-rear width. On the other hand, the front side support leg part 5b extends from the lower end of the holding part H to the fishing rod fixing part 5a by extending substantially vertically downward and bending in the horizontal direction. In addition, the front side support leg part 5b may extend from the front surface of the holding part H. According to such a structure, it becomes possible to make the direction of the reinforcing fiber of the holding part H and the direction of the reinforcing fiber of the support legs 5b and 6b along the same direction using the wide surface of the holding part H, Strength improvement, stabilization, and weight reduction can be achieved. In addition, the horizontal width of the fishing line guide can be made relatively small, the size can be easily reduced, and the entanglement of the fishing line with the guide can be reduced. In the present embodiment, the fiber reinforced resin layer (or reinforced fiber) constituting the frame 3 is continuous from the holding portion H to the support leg portions 5b and 6b.
