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.
In addition, in the above-described frame, a bent portion is inevitably formed at a portion between the fixing portion fixed to the fishing rod and the ring holding portion for holding the guide ring. When a large load is applied by being caught, there is a problem that the bent portion is easily damaged.

  The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a fishing line guide that can be reduced in weight, has excellent deflection characteristics, and can prevent breakage of a bent portion.

A fixed portion, a ring holding portion to which the guide ring is attached, and a supporting leg portion positioned between the fixing portion, and the fishing line guide is attached to a bent portion rising from the fixing portion toward the supporting leg portion. When viewed from the front, a reinforcing layer having reinforcing fibers in the vertical direction is provided.

  The fishing line guide configured as described above has a structure in which the frame portion is formed by laminating a plurality of fiber reinforced resin layers, so that the weight can be reduced and the flexibility can be improved. The fishing rod that has been made can easily exhibit its original characteristics. Moreover, even if a large load is applied to the fishing line guide, it can be damaged even if a large load is applied to the fishing line guide by arranging a reinforcing layer having reinforcing fibers along the rising direction at the bent portion rising from the fixed portion toward the support leg portion. It becomes possible to prevent.

  According to the present invention, a fishing line guide that is light in weight, excellent in bending characteristics, and capable of preventing breakage of a bent portion can be obtained.

Hereinafter, an embodiment of a fishing line guide according to the present invention will be described with reference to the drawings.
FIGS. 1 to 3 are views showing a first embodiment of a fishing line guide according to the present invention, and FIG. 1 is a front view of the fishing line guide (viewed from the front side of the fishing rod) and a frame. FIG. 2 is an enlarged view showing a laminated structure of prepregs constituting FIG. 2, FIG. 2 is a side view of the fishing line guide shown in FIG. 1, and FIG. 3 is an enlarged sectional view of a bent portion of the frame. The direction of arrow A 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 is attached so that the ring holding portion is on the tip side and the fixing portion is on the side of the fishing rod. It has been. In the following, the front side means the tip side, and the rear side means the base end side (marshal side).

  The fishing line guide 1 includes a frame 3 formed of a laminated material having a plurality of fiber reinforced resin layers in which fiber reinforced prepregs (hereinafter referred to as prepregs) in which reinforced fibers are impregnated with synthetic resin are laminated (configuration of prepregs). The detailed description of the method for manufacturing the frame and the frame will be given later).

  The frame 3 includes a fixing portion 5 attached to the outer surface of a fishing rod (rod tube) 40, a ring holding portion 7 to which a guide ring 6 through which a fishing line is inserted is attached, and a ring holding portion 7 and the fixing portion 5 And is formed in a plate shape having a width in the left-right direction larger than the thickness in the axial direction (arrow A direction in FIG. 2; front-rear direction) of the ring holding portion 7.

  The fixing portion 5 is a portion (also referred to as a foot portion) that is fixed to the surface of the fishing rod at the lower end of the frame. In the present embodiment, the fixing portion 5 extends in the axial direction, and the contact surface 5a on the back side of the fishing rod is In a state where it is placed on the surface, it is fixed by thread fastening, adhesion or the like. In addition, the fixing | fixed part 5 can take various shapes, such as one leg and two legs.

  The ring holding part 7 is a part for fastening the guide ring 6 so as to guide the fishing line in a state of being separated from the surface of the fishing rod. The ring holding portion 7 is formed with an opening for fitting and fixing the guide ring 6 and has a substantially circular outer shape as a whole. The guide ring 6 inserted into the opening is formed in a ring shape, and is formed of a member having a small sliding resistance at the fishing line guide surface 6a which is the inner peripheral surface thereof, for example, titanium, aluminum, SUS, ceramics, or the like. Has been. The guide ring 6 is fitted and fixed to an opening formed in the ring holding portion 7 after the frame 3 is integrally formed by the prepreg.

  The support leg 8 is a part for connecting the fixing part 5 and the ring holding part 7 so that the guide ring 6 is separated from the surface of the fishing rod. The support legs 8 may be formed so as to be along the vertical direction X when the fishing line guide is viewed from the front (in the axial direction of the fishing rod), or inclined with respect to the vertical direction X as shown in FIG. You may form so that it may do.

  The frame 3 is formed with at least one bent portion. In the present embodiment, a first bent portion (a bent portion that rises from the end of the fixed portion 5 toward the support leg portion 8) 10a is formed at the boundary portion between the fixed portion 5 and the support leg portion 8, and A second bent portion 10 b that is bent more gently than the first bent portion is formed on the ring holding portion 7 side of the support leg portion 8. In this case, the first bent portion 10 a is a bent portion having the steepest bending angle in the frame 3.

  When forming the bent portion as described above in the frame 3, in particular, by forming the second bent portion 10 b in the support leg portion 8, the bending angle by bending the entire frame can be set stepwise. Thus, the strength can be improved by dispersing the stress concentration. Further, if a plurality of bent portions 10a and 10b are formed in the frame 3 as described above, a bent portion (in the drawing, in the boundary portion between the fixed portion 5 and the support leg portion 8 or in the vicinity thereof) It is preferable to set the bending angle of the bent portion (corresponding to the second bent portion 10b in the drawing) formed on the support leg portion 8 smaller than that of the first bent portion 10a.

  The bent portions 10a and 10b formed on the frame as described above are regions that are easily damaged due to stress concentration, but by using a manufacturing method and a prepreg configuration as described later, the specific strength, In addition, the specific rigidity is improved. In particular, by providing a reinforcing layer, which will be described later, at the bent portion (at least the first bent portion 10a), it is configured so that it is difficult to be damaged even if a load due to a fishing line acts. In addition, about the 2nd bending part 10b, the structure which is not formed may be sufficient.

  The frame 3 is formed by pressing or the like from a prepreg (a plate-like body after thermoforming) in a state in which a bent portion having a configuration as described above is formed in advance. Is formed. In the present embodiment, as shown in FIG. 1, the support leg portion 8 rising from the end portion of the fixed portion 5 via the first bent portion 10a gradually becomes wider as it moves upward, and the guide ring 6 is attached. It is integrally connected to a substantially circular ring holding part 7 in which an opening to be worn is formed. In this case, as shown in the figure, the support leg portion 8 may be formed with an opening (thickening) 8a in order to reduce the weight.

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

  As described above, the frame 3 is formed by sequentially stacking a plurality of prepregs in which reinforcing fibers are impregnated with a synthetic resin in the front-rear direction (fishing line insertion direction; direction of arrow A in FIG. 2). In this case, for example, the prepreg is configured in a state in which reinforcing fibers such as carbon fibers and glass fibers are aligned in a predetermined direction, or in a knitted sheet shape, and a thermosetting resin (for example, epoxy resin). And a thermoplastic resin (for example, nylon) impregnated as a matrix resin. In addition, although the flame | frame 3 is comprised by the some fiber reinforced resin layer, it becomes the structure containing 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 10a and 10b are formed in the frame 3, and thus this portion is reinforced. A reinforcing layer is disposed (the configuration of the reinforcing layer will be described later).

  A plurality of prepregs stacked are set in a mold 50 as shown in FIG. The mold 50 according to the present embodiment includes an upper mold 51 and a lower mold 52 that are divided vertically, and the laminated prepreg (laminated material 20) is set at a predetermined position of the lower mold 52. Between the upper mold | type 51 and the lower mold | type 52, the cavity part 50a is formed according to the position where the laminated material 20 is set, and the mold release agent is coated in the surface area.

  The upper mold 51 constituting the mold 50 is concave and the lower mold 52 is convex, and the cavity portion (this cavity is formed between the two so that the frame 3 is formed when both are pressed. 50a is formed (corresponding to the thickness of the frame 3). Then, when the laminated material 20 is placed on the lower mold 52, the bent forming convex parts 52a and 52b are formed at positions corresponding to the bent parts 10a and 10b, and the upper mold 51 is bent. Bending formation concave portions 51a and 51b are formed corresponding to the convex portions 52a and 52b.

  Note that the laminated material 20 may be set in a lower mold in a state where the whole is overlapped at a time, or may be laminated in a plurality of times, for example, one by one. By dividing into a plurality of times as described above, the movement of the reinforcing fibers can be reduced, and the lower mold 52 can be accurately set at a predetermined position. In the present embodiment, as described above, since the mold 50 is divided vertically, the laminated material 20 is placed on the lower mold 52 and held in a predetermined shape according to the shape of the mold. Of course, the mold is merely an example, and the mold dividing direction can be in any form such as a horizontal direction or an inclined direction.

  And after setting the laminated material 20 to the lower mold | type 52, the laminated material 20 is pressurized and fixed. About this pressurization and fixation, you may clamp | tighten with the upper mold | type 51, and may press with a hand or a pressing tool. At this stage, the shape corresponding to the shape of the frame after molding, including the bent portion, is maintained, thereby preventing the occurrence of internal residual stress after molding, and the strength can be improved and stabilized. (At this stage, each prepreg is in an uncured state (including after temporary curing), and the bent portion is formed before heat curing).

Thereafter, a heating step is performed, the matrix resin is cured and molded, and then a molded product (a plate-like body 30 having a bent portion) is taken out from the mold 50.
In addition, when the above-described bent portion is pressed and cured by the mold 50, it is preferable that the bent portion is pressed relatively stronger than the front and rear regions. Thus, by strongly pressing the area of the bent portion, voids in the bent portions (10a, 10b) of the molded frame can be prevented, and the strength can be improved and stabilized. In addition, the bent portions 10a and 10b of the molded frame 3 can have a higher fiber ratio than the front and rear regions (fixed portions and supporting leg portions), so that the bent portions that are easily damaged are reinforced. It becomes possible to do.

  Next, the frame is cut out from the plate-like body 30 so as to have a predetermined shape. As described above, since the prepreg is a plate-like body in which a bent portion is formed after the heat-curing treatment, it is cut out by pressing, cut out with a liquid (water jet, etc.), cut out with a cutting tool (end mill, etc.), etc. By adopting an arbitrary method, as shown in FIG. 5, it becomes possible to cut out a plurality of frames 3 from one plate-like body 30, and it is possible to efficiently manufacture a lightweight and high-strength fishing line guide. It becomes possible.

  During this processing, it is preferable to simultaneously form the basic outer shape of the frame 3, that is, the ring holding part 7 having an opening, the support leg part 8 having an opening 8a, etc., but these are formed in separate steps. You may do it. In addition, the plate-like body 30 is not limited to a simple planar shape, but the laminated thickness is changed depending on the position, or the plate-like portion extends in a plurality of directions (T-shape, inverted Y-shape, etc.) Or a curved surface shape, or a plurality of plate-like portions may be combined.

  Next, detailed processing is performed as necessary. This detailed processing corresponds to, for example, forming the shape of the fixing portion 5 into a curved surface so that it can be easily placed on a fishing rod, or polishing the end of the fixing portion so as to facilitate winding and threading. .

  Next, a surface treatment of the frame is performed. For example, by performing barrel processing, surface burrs are removed, and finish polishing is performed to such an extent that surface gloss is obtained. Regarding the degree of this polishing, it is possible to arbitrarily adjust the polishing agent, polishing time, etc. depending on the size, shape, material characteristics, etc. of the fishing line guide. By performing such barrel processing, the frame can be polished without cutting the reinforcing fibers, the strength can be stabilized, and a fishing line guide having an excellent appearance can be obtained.

  In addition, when performing such a polishing process, it is preferable to polish so that a part of the reinforcing fibers are exposed on the surface of the frame and a part of the matrix resin remains. By doing so, it becomes possible to further improve the gloss of the polished surface.

  Next, a film is formed on the whole or a part of the frame as necessary. For example, it is possible to perform coating to improve the appearance and protect the frame body, or to deposit metal or ceramics.

  Then, the guide ring 6 is attached to the opening portion of the frame formed as described above. As a method for attaching the guide ring, press-fitting, adhesion, curling, or any other fixing method can be employed.

  According to the fishing line guide formed by the manufacturing method as described above, the weight is lighter than that made of metal, and further, the structure is excellent in specific strength, specific rigidity, and flexibility. It becomes possible. For this reason, even if a large number of such fishing line guides are mounted, the entire fishing rod is not increased in weight, and the performance of the fishing rod is improved. In particular, a portion such as a tip rod can be further reduced in weight, so that it is easy to sense delicate hits, and the performance of the fishing rod can be further improved.

Next, when the frame 3 is formed by the prepreg as described above, a preferable arrangement mode of the prepreg will be described with reference to FIGS. 1 to 3 again.
As described above, the frame 3 is constituted by the laminated material 20 having a plurality of fiber reinforced resin layers in which prepregs in which reinforcing fibers are impregnated with synthetic resin are laminated in the front-rear direction. In this embodiment, eight layers of prepregs are used as a whole, and here, for convenience, as the laminated material 20 is shifted from the front side (point side) to the rear side (general side), in order, The first layer 20a, the second layer 20b, the third layer 20c, the fourth layer 20d, the fifth layer 20e, the sixth layer 20f, the seventh layer 20g, and the eighth layer 20h are defined. In this case, the fiber direction in each layer is indicated by diagonal lines or lattice lines. In FIG. 1, the vertical direction X when the fishing line guide is viewed from the front (in the axial direction of the fishing rod) is the direction in which the fixing portion 5 of the frame 3 is raised to form the bent portion 10a. It is the direction along.

In the present invention, the reinforcing layer is arranged on the bent portion 10 a rising from the fixed portion 5 toward the support leg portion 8. In this case, in the present embodiment, the reinforcing layer is arranged over substantially the entire length of the frame extending from the fixing portion 5 to the ring holding portion 7, and accordingly, the reinforcing layer is also disposed at the bent portion 10b. It has a configuration.
Here, the reinforcement layer increases the bending rigidity of the frame 3 in the front-rear direction when the fishing line guide is attached to the fishing rod 40, and the change in the bending angle when the bent portion 10a is bent by a load is reduced. If it is a layer to be reinforced and a reinforcing fiber extending along the rising direction (vertical direction X) described above is included in any one of the prepregs constituting the laminated material 20, the reinforcing fiber is included. good. Specifically, in FIG. 1, the prepregs constituting the second layer 20b and the seventh layer 20g interposed between the plurality of fiber reinforced resin layers are reinforced fibers along the vertical direction X (rise direction). Are arranged in one direction, and have a function as a reinforcing layer for reinforcing the bent portion. And it is preferable that such a reinforcement layer is arrange | positioned in the outer layer side among the prepregs laminated | stacked so that the reinforcement effect in a bending part may be improved.

  A prepreg in which reinforcing fibers are inclined with respect to the vertical direction X is disposed on the inner layer side of the laminated material 20 to improve the strength in the twisting direction with respect to the frame. Specifically, as described above, the third layer 20c and the sixth layer 20f on the inner layer side of the second layer 20b and the seventh layer 20g functioning as the reinforcing layer have the reinforcing fibers vertically when viewed from the front. An oblique fiber reinforced resin layer obliquely inclined rightward with respect to the direction X is formed. In this case, the inclination angle in the right direction with respect to the vertical direction X is preferably in the range of more than 10 ° and not more than 60 °, and the inclination angles of the reinforcing fibers in both layers do not have to coincide with each other. Further, the inner layer side (the fourth layer 20d and the fifth layer 20e) is constituted by an oblique fiber reinforced resin layer in which the reinforcing fibers are inclined leftward with respect to the longitudinal axis X when viewed from the front. . In this case, it is only necessary to incline in the left direction with respect to the vertical direction X, but the inclination angle in the left direction with respect to the vertical direction X is preferably in the range of more than 10 ° and not more than 60 °. The oblique angles need not match exactly.

The first layer 20a and the eighth layer 20h outside the above-described reinforcing layers (second layer 20b and seventh layer 20g) are outermost layers, and the prepreg constituting this layer is a woven fabric shape. It is equipped with the reinforced fiber comprised. In this case, as shown in FIG. 1, the reinforcing fibers constituting the woven fabric are set so as to be in a direction along the vertical direction X and a direction (horizontal direction) perpendicular thereto. Is preferred.
In addition, since the layer by the prepreg comprised in such a woven fabric also contains the reinforced fiber extended in the perpendicular direction X (rise direction of a bending part), it has a function which reinforces a bending part.

  According to the configuration of the laminated material 20 as described above, the weight of the frame itself can be reduced, and a fishing line guide excellent in specific strength, specific rigidity, and flexibility can be constructed. In particular, when a slanted fiber reinforced resin layer inclined rightward and leftward with respect to the vertical direction X of the frame is disposed on the inner layer side of the laminated material 20, a fishing line such as when casting or fish is caught. Even if a load is applied to the frame 3 of the guide to bend back and forth or torsion occurs, the bending direction does not deviate, so that damage or the like can be effectively suppressed. Further, since the location where the fishing line hits the guide ring is difficult to concentrate due to the bending of the frame 3, it is possible to prevent the fishing line from being worn.

  In addition, the laminated material 20 having the above-described configuration is a fiber-reinforced resin layer (second layer 20b and seventh layer 20g) having reinforcing fibers aligned in a direction along the vertical direction X (direction along the bent portion); Since the reinforcing fiber is arranged along the curve of the bent portion, the bending rigidity is increased. Therefore, even when a load is applied such that the fishing line is caught by the fishing line guide and the bent part is pulled in the front-rear direction, breakage of the bent part can be effectively prevented. Further, at this time, although a load is applied so that a plurality of fiber reinforced resin layers are separated at the same time, the bending layer is prevented from being deformed by the reinforcing layers (the second layer 20b and the seventh layer 20g), and thus delamination occurs. It is suppressed.

  In the present embodiment, the second layer 20b and the seventh layer 20g have a structure in which the second layer 20b and the seventh layer 20g are continuously arranged from the fixing portion 5 to the ring holding portion 7, and thus the bent portions 10a and 10b described above. It becomes possible to reinforce effectively without delamination in the portion. In particular, the second layer 20b and the seventh layer 20g (reinforcing layer) are in a state of being interposed between the plurality of fiber reinforced resin layers and are located on the inner layer side of the bent portion, so that the reinforcing layer itself is peeled off. Can also be prevented.

In this case, it is preferable to arrange the reinforcing layer on the outer surface side (the tip end side having a large curvature radius) of the plurality of fiber reinforced resin layers with respect to the intermediate position (indicated by reference numeral C).
The position where the reinforcing layer is disposed is not particularly limited. However, by arranging the reinforcing layer on the outer surface side, it is possible to enhance the reinforcing effect as compared with the case where the reinforcing layer is disposed on the inner surface side (general side).

  And since the laminated material 20 of the above-mentioned structure is equipped with the fiber reinforced resin layer of a woven fabric in the front-and-rear surface (1st layer 20a and 8th layer 20h) used as the outermost layer, even if a fishing line contacts, a reinforced fiber It is difficult to cause tearing or peeling, and the strength can be improved and stabilized, and the inner fiber reinforced resin layer can be effectively protected (having a function as a reinforcing layer). That is, by disposing the woven fiber reinforced resin layers 20a and 20h as the outermost layer, the reinforced fibers can be more reliably prevented from being peeled off and damaged, and the strength can be improved and stabilized. Further, the above-described bent portions 10a and 10b can be relatively strengthened, and a fishing line guide that is lightweight and has an excellent strength balance can be obtained.

The reinforcing fiber of the fiber reinforced resin layer constituting the reinforcing layer is along the vertical direction X when the fishing line guide is viewed from the front like the second layer 20b and the seventh layer 20g so that the reinforcing effect is enhanced. However, when the fishing line guide is viewed from the front, the inclination angle is 10 ° or less with respect to the vertical direction X (in the range of + 10 ° to −10 ° with respect to the vertical direction). For example, it may be configured as a woven fabric as described above as long as it is slightly inclined or has reinforcing fibers extending in the vertical direction X.
The reinforcing layer may be provided only in the bent region of the bent portion 10a, but it is preferable that the reinforcing layer is continuously provided from the fixed portion 5 to the support leg portion 8 through the bent portion 10a.

  FIG. 6 is a view showing a second embodiment of the fishing line guide according to the present invention, and is an enlarged sectional view of a bent portion of the frame. In the embodiments described below, the same reference numerals are assigned to the layers that are the same as the layers that constitute the laminated material 20 in the above-described embodiments, and detailed descriptions thereof are omitted.

  In the present embodiment, in addition to the above-described fiber reinforced resin layer (reinforcing layer) 20b, a reinforcing piece 22 is further arranged on the outer surface side of the bent portion 10a. Such a reinforcing piece 22 includes reinforcing fibers aligned in the direction along the vertical direction X. In the present embodiment, the second layer 20b (reinforcing layer) configured as described above, It is interposed between the first layer 20a. The reinforcing piece 22 does not form the frame 3 from the fixed portion to the ring holding portion, but may be any configuration that locally reinforces the bent portion 10a (if necessary, the bent portion 10b). Specifically, the configuration is such that the bent portion 10 a is covered from the end of the fixed portion 5.

  Thus, it is possible to enhance the reinforcing effect by disposing the reinforcing piece 22 as another reinforcing layer on the outer surface side of the bent portion. Of course, such a reinforcing piece may also be installed on the inner surface side of the intermediate position C, and by being disposed relatively on the outer surface side (position close to the outer surface side of the bent portion), Can also enhance the reinforcing effect.

As shown in this embodiment, the reinforcing piece 22a does not have a predetermined length like the reinforcing piece 22 of the second embodiment, but is arranged to reinforce only the bent portion 10a. There may be.

FIG. 8 is a view showing a fourth embodiment of the fishing line guide according to the present invention, and is an enlarged sectional view of a bent portion of the frame.
As shown in this embodiment, the reinforcing piece 22b is not interposed between the layers as in the reinforcing piece 22a of the third embodiment, but the outer layer (the outer side of the fiber reinforced resin layer 20a made of a woven cloth serving as the outermost layer). ) May be provided.

FIG. 9 is a view showing a fifth embodiment of the fishing line guide according to the present invention, and is an enlarged sectional view of a bent portion of the frame.
In this embodiment, instead of the reinforcing layers (second layer 20b, seventh layer 20g) in the first embodiment described above, the oblique reinforcing fiber layer 20b ′ made of a prepreg in which reinforcing fibers are inclined with respect to the vertical direction. , 20g ′, and the strength with respect to the torsional direction with respect to the frame is further improved.
