JP 2006-340661 A

The fishing line guide described in Patent Document 1 has a problem that it is heavy because the material is metal. Further, in terms of specific strength and specific rigidity, there is a limit to using metal as a material, which has been a major obstacle to improving the total performance as a fishing rod.
In addition, since the fishing line guide is made of a metal frame, it can be made a hard and strong frame, but the flexibility cannot be ensured, and the tension applied to the fishing line is transmitted directly to the rod through the guide ring, resulting in An excessive load or impact was applied, and there was a problem that the tubule was easily damaged and easily damaged.

  The present invention has been made under such a background, and an object thereof is to provide a fishing line guide that is light in weight and excellent not only in specific strength but also in flexibility.

In order to solve the above-mentioned problems and achieve such an object, the fishing line guide of the present invention includes a fixing part fixed to the rod, a ring holding part to which a guide ring through which the fishing line is inserted, A fishing line guide having a frame having a support leg portion interposed between and connecting between the fixing portion and the ring holding portion, wherein the frame includes the fixing portion, the support leg portion, and the ring holding portion. Are integrally formed of a resin reinforced with reinforcing fibers.
According to the fishing line guide, since the frame including the fixing portion, the support leg portion, and the ring holding portion is integrally formed of the resin reinforced by the reinforcing fiber, a conventionally known metal such as stainless steel or titanium is used. Compared with the case of using a frame, the weight can be greatly reduced and the specific strength can be increased. Further, in combination with the use of a frame having a support leg portion between the fixed portion and the ring holding portion, and the fact that the frame is integrally formed of a resin reinforced with reinforcing fibers, the reinforcing fibers Therefore, it is possible to provide a fishing line guide that can fully utilize the rigidity and flexibility of the, and can ensure both high strength and flexibility.

The frame is preferably integrally formed by laminating three or more fiber reinforced resin layers obtained by impregnating a reinforced fiber with a resin.
In this case, the FRP structure fishing line guide can be manufactured by a simple method of simply stacking the fiber reinforced resin layers, and the quality can be made uniform. Further, the direction of the reinforcing fiber can be set to be multidirectional, and the strength can be further increased in this respect.

The support leg part includes a center in the left-right width direction of the fixed part and a center of the ring holding part on a virtual flat surface extended so as to remove a bent part or a curved part when the support leg part has a bent part or a curved part. It is preferable to have the reinforcing fiber inclined at a predetermined angle with respect to the center line connecting the two.
In this case, when the bending load is applied to the support leg portion, the reinforcing fiber in the support leg portion is compared with the case where the reinforcing fiber is arranged along the center line connecting the center of the ring holding portion and the center of the fixing portion in the left-right width direction. A load acts diagonally along the fiber center. As a result, it is possible to further ensure flexibility.

It is preferable that the narrow portion of the support leg has a layer in which the direction of the reinforcing fiber is arranged in a direction along the longitudinal direction of the narrow portion.
In this case, the narrow portion having relatively insufficient strength can be reinforced by the reinforcing fibers disposed in the direction along the longitudinal direction of the narrow portion, and the necessary portions can be efficiently reinforced.

The ring holding part preferably has reinforcing fibers arranged to extend in three or more directions.
Multi-directional loads are easily applied to the ring holding portion via the guide ring. In this case, by having the reinforcing fibers extending in three or more directions, the ring holding portion can sufficiently counter the multidirectional load applied through the guide ring. Further, since the deformation of the ring holding portion can be suppressed when multidirectional loads are applied, the holding force of the guide ring is improved.

It is preferable that the ring holding part has a reinforcing fiber disposed so as to extend along a circumferential direction of the ring holding part.
In this case, deformation of the portion where the guide ring is set can be suppressed by the reinforcing fibers arranged so as to extend along the circumferential direction of the ring holding portion. For this reason, the holding force of the guide ring is improved.

It is preferable that the support leg portion has a bent portion, and the thickness of the bent portion is set larger than the thickness of the ring holding portion.
In this case, efficient reinforcement can be performed by reinforcing the bent portion where the largest load is easily applied. Further, a good rigidity balance is secured with the ring holding portion reinforced by the guide ring, and the strength of the fishing line guide can be improved in a balanced manner.

At least one of the support leg part or the bent part formed on the support leg part has a bending rigidity along a reference surface perpendicular to both the fixed part and the ring holding part, along the reference surface of the ring holding part. It is preferable that it is set larger than the bending rigidity.
The fixing part is reinforced by a soot tube and the ring holding part is reinforced by a guide ring. For this reason, it is the supporting leg part that receives the largest load, and stress concentrates on the bent part among the supporting leg parts. Thus, since the bending rigidity of the support leg part to which a comparatively large load is applied or the support leg bending part where stress is easily concentrated is increased, the support leg part and the bent part of the support leg part can be prevented from being damaged or broken. Further, the weight can be reduced as compared with the case where means for increasing the bending rigidity, such as increasing the thickness, is applied to the entire frame. In other words, the strength and weight of the entire fishing line guide can be increased at the same time.

It is preferable that the said supporting leg part has a reinforcement part.
In this case, by reinforcing the supporting leg portion to which a relatively large load is applied, the strength and weight of the entire fishing line guide can be increased at the same time as described above.

It is preferable that the said supporting leg part has a peeling prevention layer which prevents peeling of a reinforced fiber or a reinforcing fiber layer in the outermost layer of a fiber reinforced resin layer.
In this case, it is possible to prevent the progress of peeling of the reinforcing fiber or the peeling of the reinforcing fiber layer from the supporting leg portion that is easily damaged by a relatively large load, and it is possible to provide a fishing line guide that is excellent in both strength and appearance.

It is preferable that the fixing portion is set such that a bending rigidity along a reference surface orthogonal to both the fixing portion and the ring holding portion is smaller than a bending rigidity along the reference surface of the support leg portion.
Since the fixing portion is reinforced by the soot tube, high bending rigidity is not required. On the other hand, the support leg is not reinforced by another member such as a soot tube, although a strong bending load is applied. For this reason, the strength as a fishing line guide can be improved in a well-balanced manner and the weight can be reduced by reinforcing the supporting leg portion that requires higher bending rigidity than the fixed portion.

It is preferable that an average thickness of the fixing portion is set larger than an average thickness of the ring holding portion.
The ring holding portion reinforced by the rigid guide ring is strongly reinforced by the fixing portion reinforced by the soot tube. For this reason, by making the average thickness of the fixing portion thicker than the average thickness of the ring holding portion, the strength as a fishing line guide can be improved in a well-balanced manner and the weight can be reduced.

  As described above, according to the present invention, it is possible to obtain a fishing line guide that is light in weight, excellent in specific strength and flexibility, and can improve total performance as a fishing rod.

<First Embodiment>
1st Embodiment of the fishing line guide of this invention is described based on FIGS.
FIG. 1 is a side view showing a fishing rod provided with a fishing line guide according to a first embodiment of the present invention. As shown in FIG. 1, the fishing rod 1 has a fishing line guide 10 and a top guide 10 ′ fixed to the rod pipe 2 at predetermined intervals in the length direction.

It is an enlarged view of the principal part.
The fishing line guide 10 includes a frame 11 and a guide ring 12 that is supported by the frame 11 and through which the fishing line is inserted. The frame 11 includes a fixing portion 13 that is fixed to the soot tube 2, a ring holding portion 14 that is disposed at a position spaced apart from the fixing portion 13 when viewed from the side, and that holds the guide ring 12, and a fixing portion 13 And a support leg portion 15 interposed between the ring holding portion 14 and connecting them.
In addition, after fixing the fixing | fixed part 13 to the rod tube 2 and winding a thread | yarn material from the outer side to the area | region shown by X in FIG. 5, a thread stopper and an adhesive agent are apply | coated, and the rod tube 2 is applied. Although fixed, the illustration of the thread material and the adhesive is omitted in FIG.

As shown in FIG. 3, the fixing portion 13 and the ring holding portion 14 are disposed so as to be spaced apart from each other at an appropriate interval and to form a predetermined inclination angle θa in a side view. The support leg portion 15 is connected to the fixing portion 13 so as to make a predetermined inclination angle θb in a side view, and to the ring holding portion 14 so as to make a predetermined inclination angle θc. A second bent portion 15B, and a flat portion 15C interposed between the first bent portion 15A and the second bent portion 15B. The predetermined inclination angles θa, θb, and θc are appropriately set according to the purpose of use and the type and diameter of the reinforcing fibers interposed in the frame 11 described later. However, the inclination angle θb of the first bent portion 15A is preferably set to a value larger than the inclination angle θc of the second bent portion 15B. For example, the tilt angle θa is set within the range of 35 ° to 100 °, the tilt angle θb is set within the range of 30 ° to 90 °, and the tilt angle θc is set within the range of 5 ° to 60 °.
Further, the flat portion 15C does not necessarily need to be flat, and is curved with a curvature that is small enough to be distinguished from the first and second bent portions 15A and 15B, instead of the second bent portion, if necessary. May be.

FIG. 6 is a front view showing an arrangement state of the reinforcing fibers R in the outermost fiber reinforced prepreg (after forming, a fiber reinforced resin layer, hereinafter referred to as “prepreg”) in the support leg portion 15 of the frame 11. It shows the stacked state of the prepreg P ₁ ~P _4, (a) the total cross-sectional view, (b) ~ (g) is a diagram showing the orientation of the reinforcing fibers in the prepreg. As shown in these figures, the frame 11 is integrally formed by laminating three or more layers (for example, about 5 to 20 layers) of prepregs P _{1 to} P _{4 in} which a reinforcing fiber R is impregnated with a resin. .

In this embodiment, the frame 11 includes a central prepreg P ₁ disposed on a central neutral shaft and intermediate prepregs P ₂ and P ₃ disposed on both sides toward the outside of the central prepreg P _1. The outermost prepreg P ₄ disposed on the outermost side is provided, and a total of seven prepregs are laminated.

As the matrix resin for the prepregs P _{1 to} P ₄ , a thermosetting resin or a thermoplastic resin is used. Specifically, an epoxy resin, a polyamide resin, a phenol resin, or the like is used.
The reinforcing fiber R for the prepregs P _{1 to} P ₄ has a tensile modulus of 3.92 × 10 ¹¹ (N / m ² ) or less (for example, 1.96 × 10 ^{11 to} 3.92 × 10 ¹¹ (N / m The high-strength fibers of ² )) are preferably used, but are not particularly limited, and any reinforcing fiber can be used. Specifically, carbon fiber, glass fiber, aramid fiber, metal fiber, synthetic resin fiber, or the like is used.

The direction of the reinforcing fiber R will be described by taking the support leg portion 15 as an example. As shown in FIG. 4, the center of the fixing portion 13 and the center of the ring holding portion 14 are included in the center prepreg P ₁ . DOO center line L connecting the (FIGS. 4 and 7 (b) ~ (e) refer) used reinforcing fibers R in one direction引揃layers disposed in parallel to, the intermediate layer prepreg P ₂ in the reinforcing fiber R of unidirectional引揃layers sloping right oblique is used with respect to the center line L (FIG. 7 (c)), is in the prepreg P ₃ of the intermediate layer, the center line L woven perpendicular to the parallel each reinforcing fiber R of unidirectional引揃e layer is used which is inclined diagonally to the left (FIG. 7 (d)), it is in the outermost layer of the prepreg P _4, with respect to the center line L for Layer reinforcing fibers are used (FIG. 7E). The same applies to the fixing part 13 and the ring holding part 14 which are other parts constituting the frame 11.

The left oblique direction of the prepreg P ₃ in the right oblique direction of the prepreg P ₂ of the intermediate layer inclination angle θd and the intermediate layer inclination angle θe is set within the range of, for example, 10 ° to 60 °. Examples of the reinforcing fiber fabric layer include plain weave, satin weave, and triaxial weave. Further, it may be woven. Further, the mesh size w of the woven fabric is set to be smaller than the minimum width of the portion to be arranged, for example, the width of the narrow portion 15E (described later) divided into two forks of the support leg portion 15.
This is merely an example, and the direction and type of the reinforcing fiber R can be appropriately changed as necessary. For example, in the central prepreg P ₁ , the reinforcing fiber R of the unidirectional alignment layer that is inclined right or left with respect to a center line L connecting the center of the fixing portion 13 in the left-right width direction and the center of the ring holding portion 14. May be used. Further, reinforcing fibers of the fabric layer may be used for any of the central prepreg P ₁ , the intermediate prepreg P _{3, and the} outermost prepreg P ₄ . In this case, it is preferable to laminate so as to change the direction of the mutual reinforcing fibers in the prepreg.

The elastic modulus of the reinforcing fibers in the central prepreg P ₁ and the intermediate layer prepregs P ₂ and P ₃ is preferably set to be higher than the elastic modulus of the reinforcing fibers R in the outermost prepreg P ₄ . This is to ensure both high strength and flexibility as a fiber reinforced plastic.

The resin impregnation amount of the prepregs P _{1 to} P ₄ is preferably set to 15 to 60 weight percent, and the center prepreg P ₁ , the intermediate layer prepregs P ₂ and P ₃ , the outermost layer prepreg P _4, and the outside It is preferable to gradually increase the resin impregnation amount as it goes. This is because the flexibility is improved, and peeling or breakage from the outer layer can be prevented.

The fixed portion 13 has a plate-like shape as a whole, and a tapered portion 13a whose thickness gradually decreases at the tip portion. The contact surface 13b of the fixing portion 13 with respect to the soot tube 2 may be formed in a concave shape so as to correspond to the outer peripheral surface of the soot tube 2.
The fixed portion 13 is preferably an average thickness T ₁ is set to be thicker than the average thickness T ₂ of the ring holding portion 14, such as the same thickness can be arbitrarily set.

  A circular hole 14a is formed in the center of the ring holding portion 14, and a guide ring 12 made of metal or ceramics is fitted therein. The guide ring 12 can be fixed to the ring holding portion 14 even if the guide ring 12 is directly formed by attaching a metal or ceramic material to the inner peripheral surface of the circular hole 14a by vapor deposition or coating in addition to press-fitting or bonding. Good. The guide ring 12 is expanded in diameter so that one side (left side in FIG. 3) expands outward. This is for preventing the guide ring from coming off and for rounding the inner peripheral portion of the guide ring in advance so as not to damage the fishing line.

Since the ring holding part 14 is formed by laminating the prepregs P _{1 to} P ₄ having the reinforcing fibers R extending in different directions as described above, the reinforcing fibers R arranged in multiple directions of three or more directions after all. Have In addition, you may arrange | position reinforcement fiber in the ring holding part 14 along the circumferential direction of the ring holding part 14 as needed. With such a configuration, a stronger holding force can be secured for the guide ring 12.

  The support leg 15 has a first bent portion 15A which is a connecting portion to the fixed portion 13 and is formed in a single curved plate shape. It is connected to the part 14. That is, the first bent portion 15A is not simply bent in the thickness direction, but extends outward along the width direction and is divided into two forks. Further, a hollow opening 15D is formed in the center of the flat portion 15C, and narrow portions 15E and 15E are formed on the left and right sides of the opening 15D, respectively. In the first bent portion 15A, the ratio of width to thickness (width / thickness) is set to about 2-9.

  Here, the narrow portions 15E and 15E of the support legs have layers in which the direction of the reinforcing fibers is arranged in the direction along the longitudinal directions Y and Y ′ of the narrow portions 15E and 15E. This layer is not limited to a single layer and may be a plurality of layers. Further, a unidirectional alignment layer disposed on the lower layer side or the upper layer side of this layer in parallel to the center line L connecting the center of the fixing portion 13 in the left-right width direction and the center of the ring holding portion 14. In some cases, a layer having a reinforcing fiber R or a layer having a reinforcing fiber of a fabric layer perpendicular to and parallel to the center line L may be provided.

  In addition, the direction along the longitudinal directions Y and Y ′ mentioned here includes, of course, a direction extending straight to the longitudinal directions Y and Y ′ in the direction parallel to the direction. The direction including the direction extending at an angle of ± 5 degrees with respect to the longitudinal directions Y and Y ′, more broadly at an angle of ± 10 degrees, is included. Further, in the narrow width portions 15E and 15E, the length of the reinforcing fiber is twice or more, more preferably three times or more the width dimension m of the narrow width portions 15E and 15E. In the support leg portion 15 of this embodiment, narrow portions 15E and 15E are formed on both sides of the central opening 15D, respectively. However, when the opening 15D is not provided, the narrow portion 15E has a width at the support leg portion. The narrowest part.

Since the support leg portion 15 is formed by stacking the prepregs P _{1 to} P ₄ having the reinforcing fibers R extending in different directions as described above, the first and second bent portions 15A and 15B at both ends are eventually removed. With respect to the center line L connecting the center in the left-right width direction of the fixed portion 13 and the center of the ring holding portion 14 on the virtual flat surface (in fact, the same surface as the flat portion 15C) extended in a flat shape The reinforcing fiber R is inclined at a predetermined angle (see FIGS. 7C and 7D). In this embodiment, as the support leg portion 15, an example in which a bent portion is provided at both ends and a flat portion 15 </ b> C is provided at the center is provided. A surface that is flattened so as to remove the curved portion is called a virtual flat surface.
The first thickness T ₃ of the second bent portion of the support leg 15 is set larger than the thickness T ₄ of the flat portion 15C. The thickness T ₄ of the flat portion 15C is set larger than the average thickness T ₁ of the fixing portion 13.

  The specific gravity of the fixed part 13, the ring holding part 14, and the support leg part 15 is preferably set to be the smallest in the order of the support leg part 15 and the ring holding part 14. This is because it is ideal that the specific gravity decreases as the distance from the axial center of the soot tube 2 increases. Moreover, it is preferable to set it as the specific gravity of 2.5 or less as the whole flame | frame 11, and it is more preferable to set it as 0.7-1.7 specific gravity.

At least one of the support leg 15 or the first and second bent parts 15A and 15B formed on the support leg 15 is a reference plane Z (on the paper surface in FIG. 3) orthogonal to both the fixing part 13 and the ring holding part 14. The bending rigidity in the direction along the parallel plane) (see the arrow directions of F and F ′ in FIG. 3) is set to be larger than the bending rigidity along the reference plane Z of the ring holding portion 14. .
Further, at least one of the support leg portion 15 or the first and second bent portions 15A, 15B formed on the support leg portion 15 has a bending rigidity in the direction along the reference plane Z at a position where the fishing line guide 10 is fixed. It is set to be larger than the bending rigidity of the soot tube 2a.
Further, the fixed portion 13 is set so that the bending rigidity in the direction along the reference surface Z is smaller than the bending rigidity in the direction along the reference surface Z of the support leg portion 15.

  As means for increasing the bending rigidity, it is only necessary to increase the second moment of section perpendicular to the bending direction. For example, the sectional area perpendicular to the neutral axis is set large. Alternatively, there is a means of increasing the thickness in the bending direction. In addition, the amount of reinforcing fibers may be increased. Furthermore, there are means such as increasing the mixing ratio of reinforcing fibers. In this embodiment, the thickness is increased, but the present invention is not limited to this, and one of other means may be employed, and two or more of the above-described means may be used in combination.

A method for manufacturing the fishing line guide according to the first embodiment will be described.
First, the prepregs P ₁ , the prepregs P ₂ and P _{3 of} the middle layer, and the prepreg P _{4 of} the outermost layer are cut into a predetermined shape, for example, a rectangular shape.
The cut prepregs are overlapped so that the extending directions of the reinforcing fibers arranged in them are in a predetermined direction (see FIGS. 7B to 7E).

  The number of layers to be superimposed (number of layers) is arbitrarily adjusted depending on the type of prepreg, the conditions for overlapping. For example, it is possible to set all the prepregs at the same time. Alternatively, the prepregs can be grouped and overlapped in advance, and finally the stacked prepregs can be further overlapped and set. Is possible. If the number of prepregs to be laminated increases, the latter can be more advantageous because it can be set with high accuracy.

The superimposed prepregs P _{1 to} P ₄ are set at predetermined positions of a mold whose surface is coated with a release material. It is also possible to directly set the prepregs P _{1 to} P ₄ one by one in the mold.
FIG. 8 is a cross-sectional view showing a state in which the prepregs P _{1 to} P ₄ are set on the molds 20A and 20B and are applied with pressure so as to have a predetermined shape. In this illustrated example, since the molds 20A and 20B divided in the vertical direction are used, the superimposed prepreg is first set on the lower mold 20B. In addition, as shown in FIG. 8, the direction of mold division is not necessarily limited to the vertical direction, and may be the horizontal direction or the tilt direction, and can be arbitrarily changed.

After the prepregs P _{1 to} P ₄ are set in the lower mold 20B in this way, the upper mold 20A is lowered and clamped and fixed, and the prepregs P _{1 to} P ₄ are heated and molded while being pressurized.
At this time, the first and second bent portions 15 </ b> A and 15 </ b> B are held so as to have a predetermined shape so as to have an angle formed by the frame 11 after molding. By doing so, generation of internal residual stress after molding can be prevented, and strength and stability can be improved.

Further, when the laminated prepreg is pressed and cured by a mold, the portion that becomes the first and second bent portions 15A and 15B has a stronger pressure than the other portion (the portion that becomes the fixing portion 13 and the ring holding portion 14). If the molding is carried out, voids can be prevented from occurring in the portions that become the first and second bent portions 15A and 15B, and the required portions can be increased in strength and stabilized. In addition, by laminating another prepreg on the portions to be the first and second bent portions 15A and 15B and performing pressure molding, the fiber ratio of the portion to be the bent portion can be made higher than the other portions. The portion that becomes the bent portion can be further strengthened.
In addition, it is preferable to set beforehand the thickness of the part used as the 1st, 2nd bending part 15A, 15B with a metal mold | die so that it may become thicker than another part.
Thereafter, the mold 20A, open the 20B, taken consisting prepreg _P 1 to P ₄ were heated and cured, the plate-shaped molded article 22 which is bent to a predetermined position from the mold.
The molded product 22 has a thickness of about 1.2 mm to 3.0 mm, and more preferably within a range of 1.2 mm to 2.6 mm.
Here, the molded product 22 has a plate shape in which a required portion is bent. However, the present invention is not limited thereto, and the shape may be a shape in which the laminated thickness changes depending on the position, or a T shape or an inverted Y shape in a side view. It is good also as a shape where a plate-shaped part divides | segments into multiple directions and extends so that a shape may be made.

FIG. 9 is a front view showing a state in which the frame 11 is cut out from the plate-shaped molded product 22. As shown in this figure, the frame 11 is cut out from the plate-shaped molded product 22. For cutting out the frame 11, there are a method using press working, a method of spraying a liquid from the tip of a nozzle such as a water jet, and a method using a blade such as an end mill.
The cutting process of the frame 11 includes three steps: the formation of the outer shape of the frame 11, the formation of the circular hole 14a of the ring holding portion, and the formation of the opening 15D of the support leg portion. These steps are preferably processed at the same time, but may be performed separately.

  Next, detailed processing is performed as necessary. For example, the abutment surface 13b of the fixing portion 13 with respect to the rod tube 2 is formed in a curved shape so that it can be easily placed on the rod tube 2, and the corners of the end portion of the fixing portion 13 are easily wound around and threaded. Is rounded to form a round.

Subsequently, barrel processing is performed to remove burrs from the surface of the frame 11, and finish polishing is performed to such an extent that surface gloss is obtained. The degree of polishing can be arbitrarily adjusted by appropriately selecting an abrasive or changing the polishing time depending on the size, shape, material characteristics, etc. of the fishing line guide 10.
At this time, it is preferable to polish the surface of the frame 11 so that the reinforcing fibers R are partially exposed and part of the matrix resin remains. By so doing, the gloss of the polished surface of the frame 11 can be made more prominent.

Next, a surface treatment for forming a coating on the whole or a part of the frame 11 is performed as necessary. For example, coating or plating may be applied to improve the appearance or protect the frame itself, or metal or ceramics may be deposited.
Next, the guide ring 12 is attached to the ring holding part 14. As a method for attaching the guide ring 12, there are a method of press-fitting or using an adhesive, a method of curling, and the like. In addition, after attaching the guide ring 12, you may perform the said barrel process and the said surface treatment.
Through the above steps, the fishing line guide 10 as shown in FIG. 3 can be manufactured.

In the embodiment, as shown in FIGS. 7B to 7E, the fixing portion 13 is disposed in parallel to the center line L connecting the center in the left-right width direction and the center of the ring holding portion 14. The prepreg P ₁ having the reinforced fibers R of the unidirectional alignment layer, the prepreg P ₂ having the reinforced fibers R of the unidirectional alignment layer inclined obliquely to the right with respect to the center line L, and the left with respect to the center line L The prepreg P ₃ having the reinforced fibers R of the unidirectionally aligned layer inclined obliquely and the prepreg P ₄ having the reinforced fibers of the fabric layer perpendicular to the center line L are used. Instead, as shown in FIG. 7 (f), the reinforcing fibers R of the unidirectional alignment layer inclined obliquely to the right with respect to the center line L and the reinforcing fibers R of the unidirectional alignment layer inclined obliquely to the left are overlapped. and prepregs _{P 5} having, as shown in FIG. 7 (g), Predetermined angle (15 degrees to 75 degrees, more preferably 30 to 60 degrees) with respect to center line L may be used prepreg P ₆ having a reinforcing fiber woven layer inclined.
Moreover, in the said embodiment, although the reinforced fiber was laminated | stacked by overlapping a prepreg, it is not restricted to this, You may laminate | stack a reinforced fiber on a part or all of a layer by a filament winding method.

Next, the function and effect of the fishing line guide having the above configuration will be described.
Since the fishing line guide 10 is integrally formed of a resin reinforced with reinforcing fibers, a frame 11 having a fixed portion 13, a supporting leg portion 15 and a ring holding portion 14 is made of a conventionally known stainless steel, titanium or the like. Compared with the one using a metal frame, the weight can be greatly reduced and the specific strength is improved. Further, the frame 11 in which the fixed portion 13 and the ring holding portion 14 are separated and the support leg portion 15 is interposed between them is used, and the frame 11 is integrally formed of a resin reinforced with reinforcing fibers. In combination, the rigidity and flexibility of the reinforcing fiber can be fully utilized, and both strength and flexibility that cannot be obtained with conventional metal guides are ensured.

In addition, the frame 11 has a configuration in which three or more layers of prepregs P _{1 to} P _{4 in} which a reinforcing fiber is impregnated with a resin are laminated and formed integrally. With such a configuration, the prepreg is simply stacked. A fishing line guide having an FRP structure can be manufactured by a simple method. Further, the quality of the frame 11 can be made uniform only by managing the spacing and orientation between the reinforcing fibers of the prepreg in advance. Further, the directions of the reinforcing fibers R can be set to be multidirectional, and in this respect, the strength can be further improved.

The reinforcing fiber R inside the support leg 15 is inclined at a predetermined angle θd, θe with respect to a center line L connecting the center in the left-right width direction of the fixed part and the center of the ring holding part on the virtual flat surface along the flat part 15C. Since it is disposed in an inclined manner, it is easy to ensure flexibility and high strength as compared with, for example, those having only reinforcing fibers extending along the center line L. That is, when tension is applied to the fishing line and bending loads in the F and F ′ directions in FIG. 3, for example, are applied to the support leg portion 15 via the ring holding portion 14, the inclination angles θd and θe are inclined with respect to the center line L. A slanting load acts on the reinforcing fibers R in the supporting leg portion along the fiber center line. For this reason, it is possible to avoid applying a strong load to the reinforcing fiber R, and as a result, it is possible to ensure flexibility.
Further, the narrow width portion 15E of the support leg portion 15 has a layer in which the direction of the reinforcing fiber R is arranged in the direction along the longitudinal direction Y, Y ′ of the narrow width portion, so that the strength is relatively insufficient. The narrow portion 15E can be reinforced by reinforcing fibers arranged in the direction along the longitudinal direction Y, Y ′ of the narrow portion, and efficient reinforcement of necessary portions can be performed.

  In addition, multidirectional loads are easily applied to the ring holding portion 14 via the guide ring 12 to be attached. By the way, in the ring holding part 14, the internal reinforcing fibers R are arranged so as to extend in three or more directions (four directions in this embodiment). Can fully counter load in the direction. Further, since the ring holding portion 14 can be prevented from being deformed in multiple directions, the holding force for the guide ring 12 is also improved.

  In addition, as what arrange | positions the reinforcement fiber R inside a ring holding | maintenance part so that it may extend in three or more directions, it is not restricted to the example shown in this embodiment, 360 degree | times is the number of orientations of a reinforcement fiber. You may arrange | position so that it may be equally divided | segmented, or you may arrange | position so that the ratio of the reinforcement fiber of the direction along the connection part with the support leg part 15 may be made high.

  Further, reinforcing fibers may be arranged in the ring holding part 14 so as to extend along the circumferential direction of the ring holding part 14. In this case, the reinforcing fibers extending along the circumferential direction can suppress deformation of the circular hole 14a, which is a portion where the guide ring is set, and can improve the holding force with respect to the guide ring 12 as described above. .

First the support leg 15, the second bent portion 15A, 15B are provided, these bent portions 15A, the thickness _{T 3} of 15B is set larger than the thickness _{T 2} of the ring holding portion 14. Efficient reinforcement can be performed by increasing the thickness of the bent portions 15A and 15B to which the largest load is applied. In addition, a good rigidity balance is secured with the ring holding portion 14 reinforced by the guide ring 12, and the strength of the fishing line guide 10 can be improved in a balanced manner.

The fixing portion 13 is reinforced by the soot tube 2, and the ring holding portion 14 is reinforced by the guide ring 12. For this reason, the largest load is applied to the support leg portion 15, and among the support leg portions 15, the bending portions 15 </ b> A and 15 </ b> B receive the largest load. By making the thicknesses T ₃ and T ₄ of the supporting leg portion 15 and the bent portions 15A and 15B of the supporting leg portion 15 which are easily loaded in this way thicker than the thicknesses T ₁ and T ₂ of the fixing portion and the ring holding portion, The bending rigidity in the F and F ′ directions in FIG. Thereby, it can prevent that the support leg part 15 and the bending parts 15A and 15B of a support leg part are damaged or broken. Further, the weight can be reduced as compared with the case where the thickness of the entire frame 11 is increased. That is, it is possible to simultaneously increase the strength and weight of the entire fishing line guide.

  In addition, as a means for increasing the bending rigidity of the support leg part 15 and the bent parts 15A and 15B of the support leg part, in addition to increasing the thickness, a center line connecting the center of the fixing part 13 in the left-right width direction and the center of the ring holding part 14 The cross-sectional area of the support leg 15 and the bent portions 15A and 15B orthogonal to L is relatively widened, the amount of reinforcing fibers R is increased, the mixing ratio of reinforcing fibers R is increased, and aramid is further increased. It is conceivable to use reinforcing fibers R having high specific strength such as fibers.

  Further, the support leg portion 15 to which a large load is easily applied is not limited to simply increasing the bending rigidity, but may be reinforced in total by using a reinforcing portion. As a reinforcing part that reinforces the support leg part 15, a reinforcing prepreg is used separately from the prepreg that forms the fixing part 13 and the ring holding part 14, and this reinforcing prepreg is laminated together with other prepregs and formed integrally. . Alternatively, a reinforcing material made of a metal material such as titanium or stainless steel or a resin material may be formed into a plate shape or a fiber shape, and these may be interposed between prepregs. Further, the reinforcing portion may be disposed over the entire support leg portion 15, or may be disposed only on a part of the support leg portion 15, for example, the bent portions 15A and 15B.

Further, in the prepreg P4 of the outermost layer of the support leg portion 15, the center in the left-right width direction of the fixing portion 13 and the ring holding portion 14 on the virtual flat surface extended so as to remove the bent portion and the curved portion. Reinforcing fibers R of a fabric layer that extend in directions perpendicular to and parallel to a center line L connecting the centers are arranged. The reinforcing fiber R of the fabric layer can prevent the reinforcing fiber from peeling off or the reinforcing fiber layer from peeling off from the support leg portion 15 where the load is most easily applied and the damage is easily advanced. An excellent fishing line guide.
In this embodiment, the outermost prepreg P ₄ of the entire frame 11 including the fixing portion 13 and the ring holding portion 14 is not limited to the support leg portion 15, and the prepreg P ₄ having the fiber layer is used. However, the present invention is not limited to this, and a prepreg having reinforcing fibers of a fabric layer only on the outermost layer of the support leg portion 15 may be used.

Further, the ring holding portion 14 is reinforced by a guide ring 12 having high rigidity, and is strongly reinforced by a fixing portion 13 reinforced by the soot tube 2. Here, the fixed portion 13 is set such that the average thickness T ₁ is thicker than the average thickness T ₂ of the ring holding portion 14. That is, by making the average thickness of the fixing portion 13 weak in strength larger than the average thickness of the ring holding portion 14, the strength as a fishing line guide can be improved in a well-balanced manner and the weight can be reduced.

Further, the fixing portion 13 has a bending rigidity in a direction along the reference plane Z orthogonal to both the fixing portion and the ring holding portion (see the arrow directions of F and F ′ in FIG. 3). Is set to be smaller than the bending rigidity.
Since the fixing portion 13 is reinforced by the soot tube 2, high bending rigidity in the direction along the reference plane Z is not necessary. On the other hand, the support leg portion 15 is not reinforced by another member such as the soot tube 2 although a strong bending load is applied. For this reason, the strength of the fishing line guide can be improved in a well-balanced manner and the weight can be reduced by reinforcing the support leg 15 that requires high bending rigidity while suppressing the bending rigidity of the fixing portion 13 from being increased more than necessary. It becomes.

  In addition, in the fishing rod 1, the fishing line guide 10 is fixed to the rod pipe with the bending rigidity in the direction along the reference plane Z of at least one of the support leg portion 15 or the bent portions 15A and 15B formed on the support leg portion. It is set larger than the bending rigidity of the soot tube 2a at the position. In this way, by setting the bending rigidity of the support leg part 15 and the bending parts 15A and 15B of the support leg part to be relatively larger than the bending rigidity of the rod tube 2a, the balance between flexibility and rigidity can be obtained when viewed from the whole fishing rod. In addition, the fishing line guide can be prevented from being damaged.
