  In the above-described known technology, since the frame is made of a metal material, the weight is heavy and the performance such as flexibility is poor, which is a bottleneck in improving the performance of the fishing rod. For example, in a fishing rod that is required to be lighter, if a large number of fishing line guides as described above are attached along the axial length direction, desired performance cannot be exhibited.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a fishing line guide that is light in weight, excellent in specific strength, specific rigidity, and flexibility, and a method for manufacturing the same.

  In order to achieve the above object, a fishing line guide according to the present invention has a frame made of fiber reinforced synthetic resin, and includes a ring holding portion through which the fishing line is inserted and a support leg portion that separates the fishing line from the surface of the fishing rod. The frame has a portion in which reinforcing fibers of a filamentous body are disposed.

  The fishing line guide having the above-described structure can be reduced in weight because the frame portion is made of fiber-reinforced synthetic resin, and the fishing rod equipped with the fishing line guide having such a structure can easily exhibit its original characteristics. . In addition, the frame constituting the fishing line guide has a portion where the reinforcing fibers in the form of filaments are arranged, so that the orientation direction of the reinforcing fibers is in the extending direction of the frame in at least a part of the frame. Since there is a portion that is in the along state, the flexibility can be improved, and a fishing line guide having high specific strength and specific rigidity can be obtained.

  In addition, in order to achieve the above-described object, a method for manufacturing a fishing line guide according to the present invention includes a frame molding groove in which a fiber reinforced synthetic resin material impregnated with a synthetic resin as a matrix material is formed in a mold. It has the process of arrange | positioning along the extension direction in the inside, and the process of heat-molding the said fiber reinforced synthetic resin material, It is characterized by the above-mentioned.

  As described above, a frame forming groove is formed in the mold, and a fiber reinforced synthetic resin material is disposed in the groove portion along the groove direction, and then the fiber reinforced synthetic resin material is heated. By molding, it is possible to easily form a fishing line guide frame having excellent flexibility and high specific strength and high specific rigidity.

  According to the present invention, a fishing line guide that is light in weight and excellent in specific strength, specific rigidity, and flexibility can be obtained, and such a fishing line guide can be easily manufactured.

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, with reference to FIG.1 and FIG.2, 1st Embodiment of the fishing line guide which concerns on this invention is described. In these drawings, FIG. 1 is a front view of a fishing line guide, and FIG. 2 is a perspective view showing an arrangement example of fiber reinforced materials constituting a frame in the fishing line guide shown in FIG. The direction of arrow D1 in FIG. 2 coincides with the axial length direction of the fishing rod when the fishing line guide is attached to the fishing rod, and the fixing portion is attached to the fishing rod with the base rod side (see FIG. 1). FIG. 2 is a view seen from the direction of arrow D1). Hereinafter, the front side (front side) means the tip side, and the rear side (rear side) means the base end side (margin side). The left-right direction is the left-right direction with respect to the axis X when the frame is viewed from the direction of the arrow D1.

  The fishing line guide 1 includes a frame 3 made of a so-called fiber reinforced synthetic resin, in which a reinforced fiber is impregnated with a synthetic resin. The frame 3 is integrated with a ring holding portion 5 that holds a guide ring 20 through which a fishing line is inserted, and a support leg portion 7 that is integrated on the lower side (fishing rod side) of the ring holding portion 5 and that has an opening 7A at the center. It has. Further, the frame 3 of this embodiment includes a fixing portion 6 for attaching a fishing rod that is bent at the end portion (lower end portion) of the support leg portion 7 and is fixed to the surface of the fishing rod by spooling, bonding, or the like. Between the holding part 5 and the fixed part 6, a support leg part 7 having the opening 7 </ b> A is provided. That is, the fixed portion 6 is integrally formed by bending the end portion of the support leg portion 7 toward the base end side. As shown in FIG. 2, the support leg portion 7 is raised obliquely upward from the fixed portion 6 so that the fishing line is not easily caught.

  By forming the support leg portion 7 between the ring holding portion 5 and the fixing portion 6, the fishing line inserted into the ring holding portion 5 (guide ring) has a certain gap with the outer surface of the fishing rod. Secure. In the fishing line guide according to the present invention, the length of the support leg portion 7 in the X direction is not limited as long as it can guide the fishing line away from the surface of the fishing rod. That is, the frame has a short distance from a fitting portion that is fixed to the surface of the fishing rod, such as a floating guide (see FIG. 12). Even so, the frame 3 </ b> B has a structure having a support leg portion 97 located between the ring holding portion 5 and the surface of the fishing rod.

  The ring holding portion 5 is formed in a plate shape having a width in the left-right direction larger than the thickness in the front-rear direction (arrow D1 direction in FIG. 2), and a guide ring 20 is fitted in the center region thereof. An opening 5A is formed. As will be described later, the opening 5A can be integrally formed when the frame 3 is molded by a mold. Further, the support leg portion 7 is formed with a through hole 7A so as to be bilaterally symmetric at a position including the center axis X, and the support leg portion 7 extends from the ring holding portion 5 via the branch portions 30 and 30 ′. A pair of left and right protrusions are provided so that the weight of the frame portion can be reduced (a structure in which no through hole is formed may be used).

  The guide ring 20 is formed in a ring shape, and is formed of a member having a small sliding resistance at the fishing line guide surface 20a, which is the inner peripheral surface thereof, such as titanium, aluminum, SUS, ceramics, or the like. As for the guide ring 20, when the frame 3 is integrally formed with a thread-like body as will be described later, an opening 5A is formed in the ring holding portion 5 and is fitted and fixed to this portion. For example, a guide ring is arranged in advance inside a portion that forms the ring holding portion, and a guide ring is formed by heating and molding a fiber-reinforced synthetic resin material wound in the circumferential direction on the outer side in the radial direction of the guide ring. It is possible to integrally form a frame to which is attached (a manufacturing method will be described later). Alternatively, after forming a frame having an opening, a guide ring may be fitted and fixed to the opening. The guide ring 20 may not be configured to be fitted into the opening 5A as a separate body. In other words, the ring holding portion 5 can be used as a separate guide ring by processing the ring holding portion 5 itself, in addition to the configuration in which the separate guide ring 20 is attached as described above. This includes a fishing line insertion opening in which a fishing line can be inserted without being attached.

  The frame 3 is made of a fiber reinforced synthetic resin material. This fiber-reinforced synthetic resin material is formed by impregnating a reinforcing fiber with a matrix material and integrally molded. For example, the matrix material is composed of a thermosetting resin or a synthetic resin made of a thermoplastic resin (fiber-reinforced synthetic resin). Resin). In this case, the reinforcing fiber is configured in a filamentous form in a manner described later, and the frame 3 includes at least a part of the fiber reinforced material that has become such a filamentous body. (The entire frame may be made of a fiber reinforced material formed into a filament.)

  Examples of the reinforcing fibers constituting the fiber-reinforced synthetic resin material (individual reinforcing fibers constituting the thread-like body) include high elastic fibers such as carbon, glass, and boron, and metal fibers such as SUS, titanium alloy, and NT alloy. Can be used. Moreover, as a matrix material which comprises a fiber reinforced synthetic resin material with a reinforced fiber, a thermosetting resin and a thermoplastic resin can be used. In this case, an epoxy resin, a phenol resin, a cyanate resin, a polyester resin, a vinyl ester resin, an acrylic resin, a melamine resin, a urea resin, or the like can be used as the thermosetting resin. In addition, as the thermoplastic resin, an adhesive rubber resin, an acrylic resin, a polyamide resin or a polysulfide resin, a thermoplastic epoxy resin, etc., a hot melt polyolefin resin, a polyester resin, a polyamide resin, Examples include acrylic resins, urethane resins, styrene-isoprene-styrene block copolymers, ethylene-vinyl acetate copolymers, and the like.

  The filament is an aggregate constituting a frame formed to have continuity with one or a plurality of reinforcing fibers, and can be used in various thicknesses depending on the frame, and a plurality of reinforcing fibers are aligned. Or a bundle of fibers in a braid shape, and it is only necessary to include reinforcing fibers oriented in the extending direction at the portion constituting the frame. The extending direction here means a direction extending in a direction including a surface constituting the frame, and at least a part of the frame (ring holding part 5, supporting leg part 7, fixing part 6, or It is only necessary that the reinforcing fiber is oriented in the extending direction of each part of the frame in the part connecting them. For example, the ring holding portion 5 of the frame extends in an annular shape surrounding the opening 5A, and the reinforcing fiber or the fiber bundle thereof is directed along an annular shape (curved shape) that matches the shape of the ring holding portion 5. Arranged. Similarly, the support leg portion 7 extends in the direction away from the left and right with respect to the axis X, and the fixing portion 6 extends in the front-rear direction. It is arranged so as to be oriented along the extending direction.

  Specifically, the reinforcing fiber constituting the fiber-reinforced synthetic resin material is a long fiber (at least 10 mm or 1 around the ring holding portion) so that the above-described constituent parts of the frame or the entire shape can be integrally formed. All of the reinforcing fibers constituting the fiber-reinforced synthetic resin material (filament) are composed of long fibers. It is preferable. For example, in the above-described frame configuration, when considering using such a fiber reinforced synthetic resin material for the ring holding part 5 and the support leg part 7, if the ring holding part 5, the ring holding part 5 in the circumferential direction is used. Although it is preferable to arrange continuously around the entire circumference, it takes into account, for example, that the physical properties of the long fibers are effectively exhibited without extending over the entire circumference, for example, continuous over a quarter of the entire circumference. It may contain reinforcing fibers. Moreover, if it is the support leg part 7, it is preferable to arrange | position to the longitudinal direction full length, but considering that the physical property of a long fiber is exhibited effectively without extending over the full length, for example, 1 of the total length / 2 or more continuous reinforcing fibers may be included.

  The amount of the synthetic resin impregnated is preferably 35% by weight ± 15% by weight in the filamentous portion. In this case, it is possible to partially distribute a large amount of resin, such as a branched portion described later or an outer layer portion having a cross-sectional shape. Furthermore, the synthetic resin impregnation amount of the entire frame or each portion (any one of the ring holding portion 5, the supporting leg portion 7 and the fixing portion 6) is determined based on the synthetic resin impregnation amount of the rod portion of the fishing rod to which the fishing line guide is attached. Increasing the number is preferable for stabilizing the strength by reducing voids and preventing interlaminar shear, and for protecting the surface fibers.

  Here, the structure of the filament used for forming the frame will be specifically described. As long as the filamentous body is impregnated with a synthetic resin and the reinforcing fibers, which are the above-described long fibers, are arranged along the axial direction, for example, a bundle of many reinforcing fibers along the axial direction is bundled. It is possible to configure in the form of a shape. That is, the filamentous body can be configured as shown in FIGS. 3A to 3G, for example.

  FIG. 3A shows a filament 25 formed by bundling a large number of reinforcing fibers (fiber bundles) 25a configured as long fibers along the axial direction. FIG. 3B shows a structure in which a large number of reinforcing fibers (fiber bundles) 25a configured as long fibers are bundled along the axial direction, and twisted as a whole to form the filament 25. FIG. 3C shows a yarn-like body 25 formed by knitting a large number of reinforcing fibers (fiber bundles) 25a configured as long fibers along the axial direction into a knitted yarn or braid. FIGS. 3D and 3E show a core material that extends in the axial direction (for example, a bundle of many reinforcing fibers, or another member that extends in the axial direction (for example, a hollow material or a foam material). The reinforcing fiber 25a may be wound around the 25b so as to be in a crossing spiral shape or circumferential direction, The thread-like body 25 is configured by knitting with a ding or the like. In addition, about the reinforcement fiber in FIG.3 (b) to (d), what was comprised as a single yarn may be sufficient.

  FIG. 3 (f) shows a sheet-like member (prepreg sheet 25c) obtained by impregnating a large number of reinforcing fibers arranged in one direction with a synthetic resin, cut into a predetermined width, and then wound to form a filament 25. In the configuration shown in FIG. 3G, a thread-like body 25 is formed by stacking a plurality of prepreg sheets 25c cut into a narrow width. Thus, the filament 25 may be one obtained by winding a prepreg sheet having reinforcing fibers aligned in the axial direction, one obtained by stacking a large number of sheets, or one having a tape shape.

  As described above, the filament 25 that forms the frame of the fishing line guide only needs to be in a state in which the reinforcing fibers are oriented in the axial direction, and the cross-sectional shape and thickness as the filament are determined. It is not limited to specific structures, such as the relationship between the reinforced fibers which comprise. That is, for the filamentous body 25, various aspects such as those in which a plurality of reinforcing fibers are aligned in the longitudinal direction, those in which a plurality of reinforcing fibers are entangled with each other, and those in which a single yarn is wound or braided, etc. Can be configured. Alternatively, a filament formed by mixing fibers of a thermoplastic resin material (eg, polyamide resin, acrylic resin, etc.) in a reinforcing fiber (eg, carbon fiber, glass fiber, etc.) may be used. The formed frame may be a combination of the configurations shown in FIGS. 3A to 3G.

  In the present embodiment, as shown in FIG. 2, the ring holding portion 5 and the supporting leg portion 7 constituting the frame 3, and also the fixing portion 6 are configured by continuously arranging the filaments 25 having the above-described configuration. It is said. Specifically, the filament 25 passes from the fixing portion 6a on one end side (left side) to the one end side (left side across the through hole 7A) 7a of the supporting leg portion 7 with the axis X as a boundary. Then, the ring-shaped ring holding portion 5 around the opening 5A is turned around (around one or more turns in FIG. 2), and the other end side of the support leg portion 7 (on the right side with the through hole 7A interposed therebetween) ) Through 7b and continuing to the fixed portion 6b on the other end side (right side). That is, the reinforcing fiber 25a constituting the filament 25 is in a state of being arranged so as to be directed in the extending direction from the fixed portion 6 to the support leg portion 7 (the support leg portion 7 to the fixed portion 6). Furthermore, it is arranged in a state where it circulates around the ring holding portion and continues along the entire frame shape. Thereby, the surrounding area of the frame 3 is reinforced by the continuous reinforcing fibers 25a of the filamentous body.

  Further, in addition to the above-described thread-like body 25, a separate thread-like body 25 </ b> A is disposed in a region from the fixing part 6 to the support leg part 7. Specifically, the filament 25A passes from the fixing part 6a on one end side (left side) to the one end side (left side across the through hole 7A) 7a of the supporting leg part 7 with the axis X as a boundary. Folded on the upper side of the through hole 7A and partially provided with the filament 25 in the opening 5A region of the ring holding part. Further, the other end side of the support leg part 7 (with the through hole 7A interposed therebetween) (Right side) It continues so that it may pass through 7b to the fixing | fixed part 6b of the other end side (right side).

  As described above, the fishing line guide is provided by continuously disposing the reinforcing fibers 25a constituting the filaments 25 and 25A in the ring holding part 5 and the supporting leg part 7 constituting the frame 3 and the fixing part 6 as well. As a result, the weight can be reduced, the flexibility can be improved, and a structure having excellent specific strength and specific rigidity can be obtained. However, when forming the frame 3, as described above, it is not necessary that all the reinforcing fibers are in a continuous state. That is, there may be a portion where the filamentous body is not partially disposed. In addition, the orientation direction, the fiber amount, and the like of the reinforcing fiber 25a can be arbitrarily adjusted when forming the filamentous body, and the type and form of the reinforcing fiber are arbitrarily selected according to the arrangement mode and the shape of the frame. It is possible. Further, as described above, the reinforcing fibers oriented in the extending direction of the frame 3 are reinforced in the extending direction when the cross section (any position where the reinforcing fibers are disposed) is viewed. It is sufficient that the ratio of the fiber occupies 1/3 or more, and more preferably occupies 1/2 or more so that the specific strength and the specific rigidity can be improved while improving the flexibility described above. .

  Further, in the present embodiment, the fishing line guide has a fixing portion 6 that is fixed to the surface of the fishing rod by winding, bonding, or the like, and that protrudes in the longitudinal direction of the fishing rod, and has a bottom surface side as a mounting surface for the fishing rod surface. However, such a fixing portion 6 is preferably formed integrally with the frame 3 in order to reduce weight and increase rigidity. Note that the fixing portion may be formed of a separate material, and the frame structure having the support leg portion 7 and the ring holding portion 5 as described above may be fixed to such a fixing portion. Also, as shown in FIG. 12, even in the case where the fishing line guide 1B is configured as an idle guide, the fixing portion 96 (the fixing portion in this case has a through hole 96a that is detachably locked to the fishing rod of the fishing rod). A cylindrical structure (to be a fixed cylinder) may be formed of a separate synthetic resin, and a frame structure as described above may be attached thereto. Of course, the fixed cylinder 96 may be integrated with the fixed portion 97 a formed integrally with the support leg portion 97.

  As described above, a more preferable configuration of the frame 3 formed by the filaments 25 will be described.

  Since the frame 3 includes the annular ring holding portion 5 and the support leg portion 7, as shown in an enlarged view in FIG. 4, the frame 3 has a branch portion that branches in different directions. That is, the frame 3 is branched in different directions at a portion (shown as a branching portion 30) where the annular ring holding portion 5 and the supporting leg portion 7 intersect. It is preferable to have a configuration in which reinforcing fibers are provided so as to extend from one branching direction to the other branching direction or to each other branching direction. Specifically, in the configuration of the present embodiment, the A-B direction (corresponding to the reinforcing fiber 25a of the filament 25), the B-C direction (corresponding to the reinforcing fiber 25a of the filament 25A), the A-C direction (filament) As in the case of the reinforcing fiber 25a of the body 25), it is preferable that the reinforcing fiber of the filamentous body is arranged so as to extend from one direction to the other branching direction at the branching portion.

  Thus, it becomes possible to improve the intensity | strength of a branch part by arrange | positioning so that a reinforced fiber may continue in a branch part. In addition, about such a branch part, it exists not only in the position as shown in FIG. 4, but in various positions depending on the structure of a fishing line guide. For example, in a two-leg type fishing line guide (see FIG. 11) as in the second embodiment described later, at the lower end portion of the ring holding portion 5, there is a support leg portion 57 on one side and a support leg portion 58 on the other side. Between them, there are branch portions 30A extending from one direction to the other direction, respectively, but in the direction D-E (corresponding to the reinforcing fiber 25a of the thread 25), the direction E-F (thread-like) The reinforcing fiber 25a of the body corresponds to the reinforcing fiber 25a) and the DF direction (corresponding to the reinforcing fiber 25a of the reinforcing fiber 25C of the filamentous body corresponds) also in the branch portion 30A from one direction to the other branch respectively. It is preferable to arrange reinforcing fibers of the filamentous body so as to extend in the direction.

  In the configuration as described above, it is preferable that the branch portions 30 and 30 </ b> A have a portion having a higher synthetic resin ratio (% by weight) than the support leg portions 7, 57 and 58. Specifically, in the configuration shown in FIGS. 4 and 11, the central portions P <b> 1 and P <b> 2 of the branch portions 30 and 30 </ b> A, or in the configuration shown in FIG. 4, the side where the through hole 7 </ b> A is formed. The portion P3 corresponds to this, and by increasing the ratio of the synthetic resin in these portions, the rigidity at the branch portion can be relatively lowered. In other words, for parts that become wider, such as branch parts, by reducing the rigidity, it is possible to prevent the load from concentrating on parts with a small width such as support legs and ring holding parts, and the overall strength of the frame It becomes possible to improve balance and rigidity balance.

  In addition, when improving the strength balance and the rigidity balance of the entire frame, the central portions P1 and P2 of the branch portions 30 and 30A are more than the outer portions 31 and 31A of the frame at the positions other than the above-described configuration. What is necessary is just to make the synthetic resin ratio high to some extent (it should just be made 10 weight% or more high). Alternatively, the synthetic resin ratio may be increased by 10% by weight or more than the ring holding part 5. Alternatively, the synthetic resin ratio may be increased in the central portion P1 of the branch portion 30 than in the portion P3 on the side where the through hole 7A is formed. Alternatively, in the configuration in which the through hole 7A is formed in the branch portion 30 as described above, the portion P3 on the through hole side has a higher synthetic resin ratio than the outer portion 31 of the branch portion 30, or the ring holding portion 5 Alternatively, the synthetic resin ratio may be increased.

  That is, the central part P1 of the branch part 30 and the part P3 in which the through-hole is formed have a synthetic resin ratio higher than that of the reinforcing fiber, or the synthetic resin ratio is relatively smaller than other parts. By increasing the number (for example, 35 to 65% by weight or more), it is possible to effectively improve the strength balance and the rigidity balance of the entire frame.

  In addition, as shown in FIG. 2, in the configuration in which the fixing portion 6 fixed to the surface of the fishing rod is formed on the frame, the bent portion 32 is formed between the support leg portion 7. About the amount of the reinforcing fiber of the part 32, it is preferable to arrange more in the support leg part 7 or more. As a result, it is possible to effectively prevent peeling or breakage of the reinforcing fibers at the bent portion where the stress acts. In addition to increasing the amount of reinforcing fiber in the bent portion 32 as described above, the synthetic resin ratio (% by weight) of this portion is increased as compared with the support leg portion 7, or the meat is larger than the support leg portion 7. The thickness may be increased or the cross-sectional area may be increased. Alternatively, a reinforcing layer may be formed by attaching a resin sheet, a prepreg sheet, a metal sheet, or the like to the bent portion 32 or the bent portion including a part of the fixed portion and the support leg portion. .

  Further, the bent portion and the fixed portion (particularly on the bent portion side of the fixed portion) connected to the bent portion may be configured by any one of the following a) to d) or a combination of two or more thereof. . That is, a) The amount of reinforcing fiber in the bent portion or the fixed portion is made larger than the amount of reinforcing fiber in at least one of the support legs (minimum fiber amount portion). B) Although it is preferable to increase the synthetic resin ratio (% by weight) as compared with the support legs, the synthetic resin ratio can be decreased and can be arbitrarily set when the amount of fibers is large. C) Thicken the wall (preferably 10% or more thicker than the support leg). D) Increase the cross-sectional area (in the case where the support leg portion is divided into a plurality of parts, it is preferable to make the cross-sectional area larger than the cross-sectional area including these plural parts).

  By configuring as described above, it is possible to prevent peeling and breakage of the reinforcing fibers in the bent portion and the fixing portion region at a position continuous to the bent portion. Further, a reinforcing layer may be formed from the fixed portion (bending portion side) to the bending portion and the supporting leg portion (bending portion side), thereby preventing the reinforcing fibers from being peeled off or damaged. Become.

  Furthermore, it is preferable that a large amount of reinforcing fiber is also disposed in the fixing portion 6 as compared with the support leg portion 7 or one end side (7a or 7b) of the support leg portion. That is, by increasing the amount of the reinforcing fiber in the fixing portion 6, it is possible to prevent breakage that causes a decrease in strength inherent to the fixing portion, such as thread winding, and to improve the strength balance of the entire guide. The amount of reinforcing fiber in the fixed part is preferably increased on the bent part side of the fixed part as in the bent part, but the amount of reinforcing fiber is preferably decreased on the opposite side of the bent part. It is possible to improve the flexibility of the fishing rod by reducing the amount of reinforcing fiber in the entire fixing portion (particularly the reinforcing fiber in the longitudinal direction) than the bent portion.

  In addition, about the above structures, it is possible to apply also to the type of fishing line guide as shown in FIG. That is, in the two-leg type fishing line guide, bent portions 82 and 83 are formed between the pair of fixed portions 75 and 76 and the support leg portions 57 and 58. As for the amount of reinforcing fiber 83, it is arranged more than the support legs 57, 58 or the synthetic resin ratio (% by weight) of these bent parts is increased compared to the support legs 57, 58. Alternatively, the thickness of the support leg portions 57 and 58 may be increased, or the cross-sectional area may be increased. Alternatively, a reinforcing layer may be separately formed on such bent portions 82 and 83.

  Next, a method for forming the frame 3 having the above-described form will be described with reference to FIGS. In these drawings, FIG. 5 is a side sectional view showing a mold structure for molding a frame constituting the fishing line guide shown in FIG. 1, and FIG. 6 is formed on the convex surface of the mold shown in FIG. FIG. 7 is a plan view showing a state in which the fiber reinforced material (filamentous body) is disposed in the groove formed, and FIG. 7 is a concave side with respect to the fiber reinforced material disposed in the groove formed on the convex surface. It is sectional drawing which shows the state which pressed the metal mold | die.

  The frame 3 as shown in FIGS. 1 and 2 can be formed by a mold 40 shown in FIG. The mold 40 can be made of a metal material, but can be made of any material (in addition to castings, ceramics, and synthetic resins, natural materials such as sand and stone may be used). The mold 40 of this embodiment is composed of an upper mold 41 and a lower mold 42 that are divided vertically. FIG. 6 shows that the upper mold 41 is opened with respect to the lower mold 42 and the lower mold 42 is moved upward. A schematic view as seen from FIG. In this case, the lower mold 42 is formed with a ridge 43 having a substantially triangular cross section in which one end surface side is a gentle inclined surface 43a, 43b and the other end surface side is a steeper inclined surface 43c. The peak portion 43 is formed corresponding to the bent portion that forms the ring holding portion 5, the support leg portion 7, and the fixing portion 6 of the frame 3. That is, the fixed portion 6 of the frame 3 is formed on the steep slope 43c side, and the connecting portion 7 and the ring holding portion 5 of the frame 3 are formed on the gentle slope 43a, 43b side.

  Such a mold 40 has a convex surface and a concave surface that are in contact with each other, and a groove for forming the frame 3 is formed on either surface side. In this case, it is preferable to form a frame forming groove 45 on the convex surface side (the surface of the lower mold 42 on which the ridges 43 are formed). Specifically, as shown in FIG. 6, the groove 45 is provided with the filaments 25 and 25A configured as described above, and the groove 45 is formed in a portion where the opening 5A of the ring holding part 5 is formed. The circular convex portion 46 is formed, and a substantially triangular convex portion 46a is formed in a portion where the through hole 7A of the support leg portion 7 is formed, and a frame forming groove 45 is formed around the convex portion. Has been. Thereby, regarding the ring holding part 5, the support leg part 7, and the fixing part 6 constituting the frame 3 shown in FIGS. 1 and 2, the filaments 25 and 25 </ b> A are continuously arranged over these parts. The thread-like body may be configured such that the thread-like body is continuously disposed over at least two of the ring holding part 5, the support leg part 7, and the fixing part 6. Moreover, it is preferable that the thread-like body is easily put in the groove 45, and it may be put in one state, but a large number of thread-like bodies may be put in the groove separately.

  As described above, by forming the frame forming groove 45 on the convex surface side (the surface of the lower mold 42 where the peak portion 43 is formed), the strength of the frame 3 having the bent region is lowered. It becomes possible to form with high quality without. Specifically, first, as shown in FIG. 6, the process of disposing the filaments 25 and 25A along the extending direction while curving (forming a loop) with respect to the groove 45 is performed. However, when the filaments 25 and 25A are embedded in the grooves 45, the tensile force S is applied to the filaments 25 and 25A at one end protruding from the mold, and the tensile force is indicated by an arrow. As shown in the figure, the filaments 25 and 25A can be deeply inserted into the groove 45 in order to move in the direction of the straight line L with no peaks.

  As described above, the filaments 25 and 25A can be easily arranged in a straight state in the groove 45 formed in advance along the extending direction of the groove. That is, it becomes possible to arrange the filaments 25 and 25A with high accuracy in the groove by a simple work, and the filaments 25 and 25A do not meander or float in the groove, improving the quality and strength. In addition, the frame 3 that can be stabilized can be formed.

  On the other hand, a convex portion 47 is formed on the upper die 41 having a concave surface so as to correspond to the groove 45 formed in the lower die 42 to be pressed. When the upper die 41 is pressed against the lower die 42, the convex portion 47 becomes a portion that presses the exposed portions of the filaments 25, 25A disposed in the groove 45. Thus, after arrange | positioning a thread-like body in the groove | channel 45, the upper mold | type 41 is pressed against the lower mold | type 42, and the process shown in FIG.1 and FIG.2 is performed by performing the heat-molding process in a pressurized state. 3 can be formed. In this case, the thread-like body that has been previously shaped into the shape of a groove in the mold (preliminarily cured) may be inserted.

  In addition, about the shape of the groove | channel 45 formed in the above-mentioned lower mold | type 42, and the shape of the convex part 47 of the upper mold | type 41 which penetrates in the groove | channel 45, regarding the cross-sectional shape of the flame | frame 3 formed, the following forms are possible. It is preferable to be configured so as to be obtained. That is, the upper mold 41 and the lower mold 42 are related to the cross-sectional shape of at least one of the support leg portion 7 and the ring holding portion 5 after the frame molding, and the maximum width portion is on the front end side or the rear end side in the front-rear direction. It is located and it is set as the structure from which this width | variety becomes small toward the other side from this largest width part. Specifically, as shown in the cross-sectional shape of FIG. 7 (the cross-sectional shape of the support leg 7 is shown, the arrow D1 direction is the front end side, and the arrow D2 direction is the rear end side), P5 which is the rear end side In this position, the cross-sectional shape has the maximum width, and the front end side, which is the other side, has a curved shape that gradually decreases in width toward the end. For this reason, the parting line of the groove 45 formed in the lower mold has a curved surface (substantially U-shaped in cross section) 48 with a narrow front end side, whereby the upper mold 41 is pressed. Thus, a frame structure having the maximum cross-sectional width on the rear end side can be easily manufactured.

  According to the frame structure having the cross-sectional shape as described above, the filamentous body is stably disposed in the groove 45 during frame molding, and the meandering and kinking of the reinforcing fiber can be reduced, and the characteristics of the reinforcing fiber are more effective. The strength of the fishing line guide can be improved and stabilized. In addition, combined with the above-described tension effect of the filamentous body, it is possible to clean the outer surface after frame molding, so it is possible to simplify or omit post-processing steps as described later. Become.

  FIG. 8 is a diagram showing a modification of the cross-sectional shape of the frame. The cross-sectional shape of the frame in this modification is provided with a curved surface having a maximum width at the position of P6 on the rear end side and a smaller width on the front end side on the other side, as in the configuration shown in FIG. However, the front end is not a curved surface but a flat surface, and the curved surface is formed so as to shift to the flat surface). For this reason, the parting line of the groove 45 formed in the lower mold is a flat front end surface 49 and a curved surface 48a gradually narrowing from the position P7 on the front end side so as to shift to the flat front end surface 49. Thus, the frame structure having the maximum cross-sectional width on the rear end side can be easily manufactured. Moreover, in this modification, the protrusion 47a which protrudes in the curved shape is formed in the center of the convex part 47 of the upper mold | type 41, and when pressing the filament 25 (25A), the recessed part curved to a rear-end surface 3e is formed. This makes it possible to reduce the weight of the frame 3 without reducing specific strength and specific rigidity. The cross-sectional shape of the frame is not limited to the above-described embodiment, but can be any cross-sectional shape depending on the shape of the groove of the mold and the way of dividing the mold (how to divide, number, direction, etc.).

  As described above, after the filaments 25 and 25A are disposed in the groove 45 along the extending direction, the matrix material is cured and the frame is formed by performing a heating process. Thus, the frame molded in the mold can be easily removed by providing the mold with a pressing pin for removing the frame from the mold or inserting the pressing pin. Detail processing is applied accordingly. For example, the detailed processing may be performed by forming the shape of the fixed portion 6 of the fishing rod into a curved shape so that it can be easily placed on the fishing rod, or by polishing the end of the fixed portion so that it can be easily wound and fastened. Applicable.

  The frame 3 may be subjected to surface treatment after molding. 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.

  Next, a film may be formed on the whole 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 20 is attached to the opening 5A of the ring holding part 5 of the frame 3 formed as described above. As a method for attaching the guide ring 20, any fixing method such as press-fitting, adhesion, curling, or the like can be employed.

  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, a structure with high quality and excellent specific strength, specific rigidity, and flexibility. It becomes possible. For this reason, even if a large number of such fishing line guides are mounted, the entire fishing rod is not increased in weight, and the performance of the fishing rod is improved. In particular, a portion such as a tip rod can be further reduced in weight, so that it is easy to sense delicate hits, and the performance of the fishing rod can be further improved. Further, since the reinforcing fiber oriented in the extending direction as described above is arranged in the region of the ring holding portion 5 and the region of the support leg portion 7, the flexibility can be improved, so that the fishing line is caught, etc. Even if a large load is applied, breakage or the like hardly occurs. Furthermore, in the area | region which transfers to the support leg part 7 from the fixing | fixed part 6, since a bending | flexion angle is large, it will be in the state effectively reinforced with the reinforced fiber which has such directionality, although a big bending stress acts. Therefore, it is possible to make it difficult to cause damage or the like.

  Further, by integrally forming the frame with the mold 40 using the filaments 25 and 25A as described above, it is easy to arbitrarily change the width, thickness, cross-sectional area, cross-sectional shape, etc. of the frame, and the degree of freedom in design. Becomes higher. In addition, it is possible to provide a high-performance fishing line guide that efficiently utilizes the characteristics of the reinforcing fiber, such as excellent specific strength and specific rigidity.

  Furthermore, in the above-described configuration, in order to improve the reinforcing effect and rigidity when the filamentous body is disposed in the groove 45, a fiber-reinforced prepreg sheet can be partially disposed and used in combination with any material. can do. In particular, by arranging auxiliary materials (for example, prepreg sheets, resin sheets, metal films, etc. cut into a predetermined shape) at parts where any of width, thickness, or cross-sectional area changes, the necessary parts can be reinforced. The rigidity can be improved.

  In the above-described configuration, the reinforcing fibers directed in the extending direction of the frame 3 may not be bundled, and the reinforcing fibers continuous along the frame are arranged at intervals. It may be. Further, the reinforcing fibers are preferably provided without being interrupted along the entire frame (in particular, the ring holding portion 5 is preferably provided without being interrupted over the entire circumference). You may provide the continuous fiber along the extending direction for every holding | maintenance part, fixing | fixed part, connection part, etc. of this.

In the above-described method for manufacturing a fishing line guide, an example in which a thread-like body for forming a frame (a fiber reinforced material in which a reinforcing fiber is impregnated with a synthetic resin) is disposed in the groove 45 of the mold has been described. Such a method may be used.
That is, the reinforcing fiber made of the material as described above is put in the groove 45 of the mold first, and then the above-mentioned synthetic resin is filled into the groove 45, or the reinforcing fiber and the synthetic resin are filled. You may put in the groove | channel 45 simultaneously. Furthermore, after filling the synthetic resin into the groove 45 of the mold, the reinforcing fiber may be put into the groove so as to be in contact with the synthetic resin. Alternatively, the above-described filamentous body may be disposed in the groove, and the reinforcing fibers may be separately placed in the groove 45 or may be filled with a synthetic resin by combining the above-described methods.

  FIG. 9 is a cross-sectional view showing a modified example of the frame structure, and FIG. 10 is a view showing a method of forming the frame shown in FIG. 9 (only the lower mold is shown).

  As the fiber reinforced material for forming the frame, for example, a plurality of fiber bundles (thread-like bodies) made of a large number of reinforcing fibers as shown in the respective drawings of FIG. 3 described above (two thread-like bodies 125a and 125b in the figure). It is also possible to configure such that the outside is covered with the outer layer 130). In this case, the outer layer 130 can be constituted by a glass scrim, a woven fabric containing carbon fibers, winding of a resin film, braiding with a plurality of reinforcing fibers, and the like. After the molding, as shown in FIG. 9, a plurality of filaments 125a and 125b and the outer layer 130 are integrated.

  In the frame structure as described above, the outer layer 130 may be wound around the outer periphery of the thread-like bodies 125a and 125b in a combined state, and may be placed in the groove 45 formed in the lower mold 42 described above. As shown in FIG. 10, first, the outer layer 130 may be disposed in the groove 45 formed in the lower mold 42, and the thread-like bodies 125 a and 125 b may be put in the groove 45. In the latter case, specifically, the groove 45 of the lower mold 42 is coated with a release agent, and the resin is coated on the groove 45 to be in a semi-dry state, and then the outer layer 130 is disposed. Then, the filaments 125a and 125b are combined and placed in the groove 45, and the protrusions 130a of the outer layer 130 are wound around the filaments 125a and 125b and arranged (the protrusions 130a of the outer layer 130 are not provided). May be). Thereafter, as shown in FIGS. 5 to 8, the frame can be formed by pressing the upper mold 41 against the lower mold 42 and performing a heat forming process in a pressurized state.

  Thus, by winding the outer layer around the thread-like body, delamination of the reinforcing fibers and the thread-like body can be prevented, and the strength can be improved. Further, by providing the outer layer 130, it is possible to improve the appearance as a colored outer layer or a woven outer layer of reinforcing fibers.

  In the configuration described above, the two filaments 125a and 125b are wound around the outer layer 130. However, there may be one filament or three or more filaments. When there are two or more thread-like bodies, peeling between the thread-like bodies can be prevented by inserting stitches (sewing) at the boundary portions between the thread-like bodies. Moreover, about the outer layer 130, the structure wound partially may be sufficient besides winding the whole outer periphery. In this case, in the case of a plurality of filamentous bodies, it is preferable in terms of strength to cover at least a part of the boundary portion. Further, by continuously covering the entire circumference (360 ° in FIG. 9) for 180 ° or more, the appearance when viewed from a specific direction can be improved. The outer layer 130 is preferably provided with reinforcing fibers in the circumferential direction so as to surround the filamentous body. In particular, bending portions and branching portions can be improved in strength by arranging reinforcing fibers in the circumferential direction. Furthermore, the structure which does not need to improve an external appearance and is hard to visually recognize may be the structure which does not wind an outer layer.

FIG. 11 is a view showing a second embodiment of the fishing line guide according to the present invention, and is a side view showing the directing direction of the reinforcing fiber of the fiber reinforcing material. FIG. 12 is a view showing a third embodiment of the fishing line guide according to the present invention.
The present invention is not limited to the one-leg type fishing line guide as in the above-described embodiment, and can be applied to various forms of fishing line guides.

  FIG. 11 shows a two-leg type fishing line guide 1A, and the frame 3A is arranged on the rear end side and the tip side from the ring holding part 5 holding the guide ring 20 and the lower side of the ring holding part 5, respectively. Supporting leg portions 57 and 58 extending toward the end, and fixing portions 75 and 76 bent at the ends of the respective supporting leg portions 57 and 58 are provided. These portions can also be formed by the filaments 25, 25B, and 25C in which a large number of reinforcing fibers are configured in a bundle shape in the axial direction, as in the above-described embodiment. Further, such a frame 3A can be formed, for example, in such a form that the upper mold is divided into left and right split molds that are divided by the portion of the frame 3A, and such a left and right split mold is pressed against the lower mold. . As shown in FIG. 11, in the configuration in which the guide ring is fixed to the ring holding portion, the thickness a of the ring holding portion 5 is the width in order to increase the fixing (adhesion) area of the guide ring. It is preferable to make it larger than b. In addition, the branch portion can increase the amount of reinforcing fiber or the ratio of reinforcing fibers than the support leg portion. In this case, the bending rigidity (specific rigidity) of the branch portion can be increased, and the strength of the branch portion can be intensively enhanced.

  The present invention can be applied to various types of fishing line guides. In addition to the configuration shown in FIG. 11, the fishing line guide (as shown in FIG. 12) having a fixing portion to be inserted into a swing-out type fishing rod. Further, the present invention can be applied to an idle guide 1B) having a fixed cylinder 96, or a top guide mounted on the tip rod. Further, the frame structure (for example, the shape and configuration of the support leg) is not limited to the configuration of the above-described embodiment.

Next, a preferred example of the ring holding portion of the fishing line guide frame formed as described above will be described with reference to FIGS.
As described above, the frame can be formed using, for example, a filamentous body as shown in FIG. 3, and the ring holding portion 5 is in a state where such a filamentous body is annularly arranged. ing.

In such a configuration of the ring holding portion 5, it is preferable to arrange the reinforcing fiber states on the inner peripheral side (guide ring side) A1 and the outer peripheral side A2 as follows.
That is, as a first example, as shown in FIG. 14, for example, the reinforcing fiber on the outer peripheral side A2 has a smaller crossing angle with respect to the circumferential direction, and the reinforcing fiber on the inner peripheral side has a relatively larger crossing angle than the outer peripheral side. Form.
FIG. 14 is an enlarged view showing the fiber state of the fiber-reinforced synthetic resin material constituting the ring holding portion. As shown in this figure, the reinforcing fiber F1 on the inner circumferential side A1 has a crossing angle θ1 with respect to the circumferential direction C relative to the circumferential direction C of the reinforcing fiber F2 on the outer circumferential side A2 as compared with the outer circumferential side A2. It arrange | positions so that it may become larger than crossing angle (theta) 2.

  By setting the state of the reinforcing fibers located in the ring holding part 5 as shown in FIG. 14, the inner peripheral side of the ring holding part is in a state in which the intervals between the reinforcing fibers are relatively clogged and inserted. The tendency for the reinforcing fibers to come into contact with the outer periphery of the guide ring 20 is increased, whereby the guide ring 20 can be stably held. In addition, as described above, the reinforcing fiber on the inner peripheral side has a relatively large crossing angle, so the temperature changes (the influence of heat during molding, the influence of heat generated by the insertion of fishing line during use, etc.) Even if the guide ring part is thermally deformed and the deformation in the circumferential direction is larger than that on the outer peripheral side, the reinforcing fiber can easily follow the thermal deformation of the guide ring, and the fixing state of the guide ring is stabilized. I can plan. That is, even if the temperature changes, internal stress is less likely to be generated in the guide ring 20 with the ring holding portion 5, and impact from the outside can be mitigated, and stable guide ring can be held. .

As a second example, for example, as shown in FIG. 15, the reinforcing fiber on the outer peripheral side A2 is linear with respect to the circumferential direction or has a small meandering amount, and the reinforcing fiber on the inner peripheral side is relatively closer to the outer peripheral side. It is formed so as to increase the amount of meandering.
FIG. 15 is an enlarged view showing a fiber state of the fiber-reinforced synthetic resin material constituting the ring holding portion. As shown in this figure, the reinforcing fibers F1 on the inner peripheral side A1 are arranged so that the amount of meandering is larger than that of the reinforcing fibers F2 on the outer peripheral side A2 as compared with the outer peripheral side A2.

  Even in such an arrangement, the meandering inner peripheral side is more likely to come into contact with the outer periphery of the guide ring 20 into which the reinforcing fiber portion is inserted, thereby stabilizing the guide ring 20. Can be held. In addition, since the reinforcing fiber on the inner circumference side is meandering and easily displaced along the circumferential direction, temperature changes (effect of heat during molding, influence of heat generated by insertion of fishing line during use, etc.) Even if the guide ring part is thermally deformed, the deformation in the circumferential direction is larger than that on the outer peripheral side, so that the reinforcing fiber can easily follow the thermal deformation of the guide ring, and the fixing state of the guide ring can be stabilized. That is, even if the temperature changes, internal stress is less likely to be generated in the guide ring 20 with the ring holding portion 5, and impact from the outside can be mitigated, and stable guide ring can be held. .

  14 and 15, the inner peripheral side A1 and the outer peripheral side A2 are shown adjacent to each other, but a plurality of intermediate layers (direction and thickness of reinforcing fibers, number of layers, Any number of filamentous bodies may be provided.

  Thus, by increasing the ratio of the reinforcing fibers on the outer peripheral side, the rigidity of the outer side of the ring holding part 5 becomes larger than that of the inner side, and the strength can be improved. Further, since the ratio of the reinforcing fibers is relatively small on the inner peripheral side of the ring holding portion, it is easily deformed and internal stress is generated in the guide ring 20 between the ring holding portion 5 even if a temperature change occurs. It becomes difficult and the impact from the outside can be reduced, and the guide ring can be held stably.

FIG. 16 is a view showing a modification on the base end side of the support leg portion of the frame formed as described above.
As described above, the fishing line guide frame as shown in FIG. 13 can be formed by the manufacturing method described with reference to FIGS. In this case, in the bending region where the fixing portion 6 transitions to the support leg portion 7, when the filamentous body is disposed along the longitudinal direction, the filamentous body is branched into two branches via the bending portion (see FIG. 1 and FIG. 1). In this branch region, there is a possibility that the strength decreases.

For this reason, as shown in FIG. 16, it is preferable to arrange the reinforcing member 100 in a bifurcated portion (an opening region 200 on the base end side divided into two forks). In this case, the reinforcing member 100 is preferably made of the same fiber-reinforced synthetic resin material as that of the filamentous body that forms the frame. That is, by using the same material as the frame, it is possible to prevent the reinforcing member from peeling off. Further, by forming the reinforcing member 100 such that the height h2 thereof is higher than the height h1 of the fixed portion 6, the torsional strength of the frame can be effectively improved.
In addition, such a reinforcing member 100 is disposed in the gap between the bifurcated branch portions when the filamentous body is disposed in the groove 45 as shown in FIG. 6, or the filamentous body itself is bent. What is necessary is just to arrange | position in the area | region. By arranging the reinforcing member in such a position, the supporting leg portion that branches after the mold is heated and molded is reinforced by integrally joining the opening region of the base end portion thereof. Become. The reinforcing member 100 can be made of synthetic resin or metal material.

FIG. 17A is a view showing another modification on the base end side of the support leg portion of the frame, and FIG. 17B is a cross-sectional view of the base end side of the support leg portion.
The reinforcing member 101 of this modified example is disposed in the peripheral region in addition to the opening region 200 of the branching portion that is divided into two branches of the support leg portion. As described above, the reinforcing member can be provided in the peripheral region in addition to the opening region of the branching portion that is divided into the bifurcated portions of the support leg portion, thereby further enhancing the reinforcing effect (improving torsional strength). In addition, such a reinforcing member 101 is flush with the surface of the frame so that the reinforcing member does not protrude, as shown in the drawing, on the side where the fishing line is caught and pulled out, i.e., on the surface of the frame side of the frame, Surface treatment may be performed so as not to cause unevenness.

FIG. 18 is a view showing another embodiment of a mold structure for forming a frame constituting a fishing line guide.
In this example, it is a figure which shows an example of the method of mounting | wearing with a guide ring simultaneously with shape | molding a flame | frame with a metal mold | die. As shown in the figure, the mold 40A is basically composed of an upper mold 41A and a lower mold 42A as in the embodiment shown in FIG. 5, but the lower mold 42A has a guide ring. In order to form the fixed ring holding portion, a punching die 42B is provided (the punching die is pulled downward in the figure). A cylindrical convex portion 42C is formed at the upper end portion of the punching die 42B, and the guide ring 20 is provided between the cylindrical convex portion 42C and the lower die 42A and between a groove 45A described later. And space S1 in which the fiber reinforced synthetic resin material used as a ring holding part is arranged is formed.

  Further, the upper die 41A is formed with a circular recess 41C corresponding to the position where the ring holding portion is formed (specifically, corresponding to the position where the guide ring 20 is disposed). A frame forming groove 45A is formed between the upper mold 41A and the lower mold 42A, as in the configuration shown in FIG.

  When the frame is formed by the above-described mold structure, first, the die 42B is set on the lower mold 42A, and a burr preventing member (a material having a good sealing property) is formed on the outer circumferential step portion of the cylindrical convex portion 42C. (For example, a soft member such as rubber) 44 is disposed, and the guide ring 20 is fixed thereon so as to be fitted around the cylindrical convex portion 42C. Then, the filament 25 is disposed in the groove 45A along the extending direction thereof, and is disposed so as to wind around the outer peripheral side of the guide ring 20 fixed in the space S1, and then also in the recess 41C. A burr prevention member (soft member) 44 is disposed, and the upper die 41A is pressed against the lower die 42A to pressurize and heat. At this time, as shown in FIG. 18, the guide ring 20 is in a state where the upper and lower sides are pressed by the burr preventing member 44 (the guide ring is sandwiched and sealed by the burr preventing member). During the heating process, the resin does not flow into the guide ring 20 from the ring holding portion region.

  Then, after the heating step is finished, the punching die 42B is pulled out and the upper and lower dies 41A and 42A are divided, whereby the frame on which the guide ring 20 is mounted is formed. In this case, since the resin does not flow to the inner surface side of the guide ring 20 by the burr preventing member 44 during the heating process, it is possible to prevent burrs from being generated at the boundary portion between the guide ring 20 and the ring holding portion.

  Of course, the manufacturing method for simultaneously mounting the guide rings as described above is only an example, and it is possible to appropriately change the arrangement mode of the burr preventing member, the direction in which the mold is pulled out, and the like.

  As described above, when the guide ring is mounted on the ring holding portion, the guide ring formed of a material such as SIC or titanium is fixed to the ring holding portion, and the ring holding portion itself is a guide ring or guide ring. There is a method of forming as a part of. And, in the case of the method of fixing the guide ring like the former to the ring holding part, as shown in FIG. 18, a method of arranging the fiber reinforced synthetic resin material and the guide ring in the mold and fixing them while simultaneously molding them. After the frame is formed by various methods, the guide ring is bonded to the ring holding portion by bonding or welding, or the guide ring is bonded to the frame at the final step after polishing or surface treatment. It is possible to attach the guide ring to the ring holding part at any stage of the manufacturing process.

  Further, when the ring holding part is formed as a guide ring or a part of the guide ring, a smooth fishing line guide that guides the fishing line to the ring holding part at the same time when the fiber reinforced synthetic resin material is arranged and molded in the mold. A method for forming a surface, a method for forming a fishing line guide part by polishing the ring holding part after forming a frame, or a wear-resistant ceramic material, metal material for the fishing line guide part of the ring holding part, It can be formed by coating a synthetic resin material or the like and smoothly polishing the surface as necessary.

  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, any one of the frame portions constituting the fishing line guide 1 only needs to include a portion in which the reinforcing fibers are formed into a thread-like body. That is, the reinforcing fiber of the fiber reinforced synthetic resin constituting the frame only needs to be oriented in the extending direction of the frame, and such reinforcing fibers are not necessarily configured in bundles with a large number. It is not necessary. Further, the type of reinforcing fiber oriented in the extending direction of the frame, the elastic modulus, the resin impregnation amount, the diameter and the like, the arrangement state, and the like are not limited to the above-described embodiment, and may be variously modified. Is possible.

  In addition, it is possible to appropriately change the manner in which the filaments are arranged when the frame is formed using the mold. For example, in addition to the arrangement example of the filamentous body shown in FIG. 2, the filamentous body is disposed in an annular shape around the ring retaining portion 5, and the ring retaining portion is substantially half-circulated from the fixing portion on one end side via the support leg portion. After winding, the thread-like body may be arranged so as to reach from the supporting leg portion on the other end side to the fixed portion (as shown in FIG. 2, it is not necessary to wind once around the ring holding portion). . Further, the filamentous body can be appropriately modified, such as being arranged in an annular shape or a substantially C shape with respect to the groove formed in the mold. Further, the frame molding die 40 described above is merely an example, and the mold splitting direction can be set to an arbitrary form such as a horizontal direction or an inclined direction.
