Abstract

PROBLEM TO BE SOLVED: To provide a fishing rod guide having two support legs formed by three pairs of heat-curable prepregs, in which such a phenomenon is prevented that strength between products is not always uniform due to the presence or absence of void generated in a branch part of the legs.SOLUTION: The branch parts of the two support legs of the fishing rod guide having the two support legs formed by three fiber-reinforced resin layers provided to a fishing rod are sealed with a heat-curable resin member or prepreg to thereby prevent stripping off and breaking of the prepreg in the branch part.

Description

  The present invention relates to a fishing line guide formed of a resin material impregnated with reinforcing fibers and a fishing rod provided with the fishing line guide.

  Among general fishing rods (hereinafter referred to as fishing rods), there is a fishing rod provided with a plurality of fishing line guides (hereinafter referred to as fishing line guides). The fishing line guide provided on these fishing rods is attached to either the upper surface or the lower surface of the rod depending on the type of reel used.

  For example, in the case of a fishing rod equipped with a biaxial reel (or bait reel used in freshwater and seawater) often used for boat fishing, the fishing line guide is attached to the upper side of the fishing rod. On the other hand, in the case of a fishing rod equipped with a spinning reel that is used mostly on rods, sandy beaches, or ponds, the fishing line guide is attached to the lower side of the fishing rod. These fishing line guides are usually configured by fitting a guide ring made of SiC or the like that is inserted into and supported by a frame made of a metal material such as titanium or stainless steel.

JP 2011-004651 A

  With the progress of fishing rod manufacturing technology, the strength has been improved, and the weight of the rod has been reduced as the diameter is reduced. When a large number of fishing line guides having the above-described metal frame are attached to a fishing rod that achieves this weight reduction, the weight of the entire rod is increased. For example, in a fishing rod using a spinning reel, for example, a throwing rod having a length of more than 4 m that disposes a device from the beach, there is a demand to increase the flying distance as much as possible. Therefore, since the flying distance is affected by the speed at which the rod tip swings out as well as the flexible flexibility of the fishing rod, the long throwing operation is greatly affected by the degree of deflection of the rod and the weight reduction.

  As a fishing line guide that realizes weight reduction, for example, in Patent Document 1, a prepreg, that is, a frame made of reinforced fibers such as carbon fiber or other prepregs, which is impregnated with a thermosetting resin, is formed. A fishing line guide has been proposed. In Patent Document 1, a fishing line guide having a monopod (so-called single foot) supporting leg portion connected to one fixed portion and a bipod (so-called double foot) connected to the two fixed portions formed by a pre-gre. A fishing line guide having a support leg has been proposed. For the biped fishing line guide, only a conceptual configuration is presented.

  When this biped fishing line guide is actually formed, there is a structure in which there is a branching point that branches from one ring holding portion to the front and rear support legs. As shown in FIG. 11, the branch portions are bonded and thermally cured so that the three sets of sheet members 11, 12, and 13 come into contact with each other. These sheet members are formed in a woven fabric in which reinforcing fibers such as carbon fibers are knitted into a plain weave, or in an aligned form in which the fibers are arranged side by side. For this reason, if a crease is made at the time of bonding, there arises a problem that each thin fiber breaks and becomes weak in strength.

  For this reason, as shown in FIG. 11, at least one sheet member 13 is addressed from the lower side to the branching point A of the two sets of sheet members 11 and 12 that branch forward and backward from the ring holding portion. It becomes a structure which mutually contacts. When these sheet members are cured, the central portion 19 of the branch point A becomes a gap or becomes sealed with the resin that has oozed out from each sheet member, resulting in manufacturing variations in the fishing line guide.

  Even if a fishing line guide that satisfies the design performance (manufacturing standard) has a gap at the branching point, it is a non-defective product in which the center part of the branching point A is sealed by the user's appearance. May be judged as a defective product.

  Accordingly, the present invention provides a fishing line guide formed of a resin material impregnated with a lightweight reinforcing fiber and a fishing rod provided with the fishing line guide, in which the presence or absence of gaps at branch points is unified and there is no manufacturing variation. Objective.

  In order to achieve the above object, a fishing line guide according to an embodiment of the present invention includes a fishing line guide portion that guides a fishing line, and a first portion that extends from the end portion of the fishing line guide portion to one side and is provided with a fixing portion at the tip end. A leg part and a second leg part branching from either the end part of the fishing line guide part or the first leg part and extending to the other and having a fixing part at the tip are integrally configured. A first fiber reinforced resin layer formed by laminating a plurality of sheet-like synthetic resins including reinforcing fibers, which form the fishing line guide portion and the first leg portion, and the branched portion From the first leg portion, the second fiber reinforced resin layer, which is fixed to the first fiber reinforced resin layer and laminated with the synthetic resin forming the fishing line guide portion and the second leg portion. It reaches the second leg through the branching point, and the first fiber reinforced resin layer and the second leg. A third fiber reinforced resin layer in which the synthetic resin fixed to the fiber reinforced resin layer is laminated, and the branched portion surrounded by the first fiber reinforced resin layer to the third fiber reinforced resin layer. And a branch gap member positioned at the same position.

  According to the present invention, a fishing line guide that is unified with the presence or absence of gaps at branch points, has no manufacturing variation, and is formed of a resin material impregnated with reinforcing fibers and is reduced in weight with high strength, and a fishing rod provided with the fishing line guide. Can be provided.

[First Embodiment]
FIG. 1 is a diagram showing an external configuration of a fishing rod provided with a fishing line guide according to an embodiment of the present invention, FIG. 2 is a diagram showing an external configuration of a fishing line guide according to the first embodiment, and FIG. It is a figure for demonstrating cross-sectional structure.

  The fishing rod 1 of this embodiment is a type in which a double-axis reel (or bait reel) (not shown) is mounted on the reel seat 3 of the bat 2, and a plurality of fishing line guides 5 are provided on the upper surface of the rod body 4 at intervals. A top guide 6 is provided at the tip of the hook. In the following description, the tip side of the fishing rod is referred to as the front, and the heel side is referred to as the rear.

  The fishing line guide 5 includes a frame 8 formed of a fiber reinforced resin material impregnated with a resin, which will be described later, and a guide ring 7 made of SiC or the like. The guide ring 7 is fitted in a ring-shaped ring holding portion (fishing line guide portion) 8 a provided on the upper portion of the frame 8. In each of the embodiments including the following, the ring holding portion 8a has an annular shape such as a circle, an ellipse, an oval, a track shape, and the like, and its end is all on the peripheral end, for example, the upper end, the lower end, and the side Includes edges.

  FIG. 2 shows a fishing line guide 5 having two support legs 8b and 8c as an example. These support legs 8b and 8c have a height (length) for separating the fishing line (road line) from the fishing rod by a predetermined distance. In the description of the present embodiment, of the two legs of the fishing line guide shown in FIG. 3, a main leg that extends substantially linearly from the ring holding part (fishing line guide part) 8a and fixes the leg connected to the fixing part to the rod. Part (first leg) 8c. Further, the leg branched from the other ring holding part 8a and connected to the fixing part is referred to as an auxiliary leg part (second leg part) 8b for supporting the main leg part 8c and preventing thread warp. Of course, the fishing line guide 5 may fix any leg part toward the tip of the hook or the bottom of the hook, and the main or auxiliary relationship in the leg part is not limited.

  The main leg portion 8c extends along the frame surface from two midpoints of the ring holding portion 8a, forms a V-shape by lightening to reduce weight, is bent horizontally, and is connected to the fixing portion 8e. . The auxiliary leg portion 8b is branched at a branching point A obliquely downward from two points in the middle of the ring holding portion 8a, has a V shape, and is horizontally bent and fixed to provide a guide for preventing entanglement of the fishing line. It is connected to the part 8d. Each of the fixing portions 8d and 8e is placed at a predetermined position of the fishing rod, is fixed by winding a thread, and is subjected to wrapping and coating processing with a resin or the like from the surface of the thread.

  FIG. 4 is an enlarged cross-sectional view of a branch point in the fishing line guide. As shown in FIG. 4, the frame 8 includes a laminated sheet 11 (first fiber reinforced resin layer), a laminated sheet 12 (second fiber reinforced resin layer), and a laminated sheet 13 (third The fiber reinforced resin layer) is abutted and thermally cured. These prepregs are sheet members impregnated with a matrix resin that is knitted into a plurality of reinforcing fibers, for example, carbon fibers arranged in the same direction, or woven into a plain weave or the like and cured by heat processing. These sheet members are superposed by combining the fiber directions of the reinforcing fibers into a plurality of directions so that the frame 8 has strength based on the design value. In this case, the strength in the direction along the fiber direction is increased. When a prepreg in which reinforcing fibers are knitted into a plain weave or the like is used, the knitting width is set to be a width narrower than the width of the frame portion having the minimum finished dimension, for example, the auxiliary leg portion 8b.

  Further, the bending radius (R) of the main leg portion 8c and the auxiliary leg portion 8b at the branch point A is preferably at least such that damage such as bending of the reinforcing fiber does not occur. This degree varies depending on the material of the reinforcing fiber used, the fiber diameter, the fiber arrangement direction (alignment direction), and the like, and has various numerical values. When used for a guide, assuming that the layer thickness t1 of the main leg 8c is the layer thickness t2 of the auxiliary leg 8b, the radius R is larger than t1 and t2, for example, the radius R is preferably 2 mm or more.

  As the reinforcing fiber in the present embodiment, glass fiber, aramid fiber, metal fiber, synthetic resin fiber or the like can be used in addition to carbon fiber. Moreover, as a matrix resin, a thermosetting resin or a thermoplastic resin can be applied, for example, an epoxy resin, a polyamide resin, a phenol resin, an unsaturated polyester resin, etc. can be used. As the branch gap member 14, other members are not as rigid as the matrix resin, but ABS resin, synthetic rubber, foaming material, and the like can also be applied. However, among the other members, members that do not dissolve at the curing temperature of the matrix resin are preferable. A material that is less rigid than the fiber-reinforced resin layer forming the frame can be easily deformed and can be a guide that is not easily damaged.

  The branch point A shown in FIG. 11 described above is bonded and thermally cured so that the three laminated sheets 11, 12, and 13 come into contact with each other from three directions. The conventional branch point A is sealed due to the generation of voids or oozing of excess resin.

  This bifurcation point A has a first action or two legs in which when the attached fishing rod is bent, the distance between the two legs is narrowed and the fishing line is pulled up in the direction of pulling the ring holding part 8a away from the fixing part (pulling the support leg part). One of the second actions occurs in which the gap is widened and the fishing line presses the ring holding portion 8a downward toward the fixed portion. In other words, a fishing rod using a spinning reel with a fishing line guide disposed below the fishing rod has a first action when the fishing line is loaded and bent downward. On the other hand, when a fishing line guide is disposed on the upper side of a fishing rod and a double rod reel is used, the fishing line is loaded with a load and bent downward. These actions are due to the change in the load applied to the fishing line, the bending state of the fishing rod changes, and the load applied directly from the fishing line also changes, so that the fishing line guide 5 is subjected to a load that changes in strength or vibration. Yes. Due to these loads, a pressing or peeling force acts on each joint surface of the three sets of laminated sheets 11, 12, and 13 at the branch point A.

  Therefore, in this embodiment, as shown in FIG. 4, the gap at the branch point A is integrally provided so as to be filled with a branch gap member 14 made of a resin material equivalent to the sheet member. Since this branching gap member 14 is in close contact (welding) to each joint surface of the laminated sheets 11, 12, 13, the force acting between the joint surfaces can be reduced. Moreover, the peeling or crack which arises between the joint surfaces of a lamination sheet is prevented.

  FIG. 5 is a diagram conceptually showing production by press molding for forming the fishing line guide of the present embodiment. FIG. 6A shows an external configuration of a cured prepreg molded product including a fishing line guide manufactured by press molding, and FIG. 6B shows a configuration through which a branching portion of the cured prepreg molded product is seen through. FIG.

With reference to FIG.4 and FIG.5, shaping | molding of the fishing line guide 5 by the lamination sheets 11, 12, and 13 containing the branch gap member 14 is demonstrated.
In the present embodiment, laminated sheets 11, 12, and 13 in which a plurality of thin prepregs are stacked are loaded into dies 21, 22, and 23 for press molding. The surface of these molds is provided with a recess for setting the laminated sheet. Loading and holding of the laminated sheets 11 and 12 to the molds 21 and 22 may be held by mechanical parts such as metal claws or may be held electrically such as electrostatic adsorption. A release agent may be applied so that the laminated sheet can be easily removed after molding.

  Next, the molds 21, 22, and 23 are brought into contact with each other at a predetermined position as shown in FIG. 5 by a processing device (not shown). At that time, the branch gap member 14 is inserted so that the convex portion (tip portion) of each mold is sandwiched between the opposing portions (branch locations). The branch gap member 14 has a rod shape having a length exceeding the width of the laminated sheet, and uses a triangular shape whose cross section is close to the internal shape of the branch point. Although the cross section of the branch gap member 14 may be rectangular, there is a concern that corner portions of the branch gap member 14 may damage the laminate sheet during pressurization during thermal processing. Or the shape which touches by a curved surface is preferable.

  The prepreg molded product 20 is taken out from the cooled molds 21, 22, and 23. A thermoset prepreg molded product 20 including the frame 8 as shown in FIG. 6A is formed. Moreover, as shown in FIG.6 (b), in the branch location A, the resin member 14 melt | dissolves, it fills up a clearance gap, and it forms so that it may contact | adhere to each lamination sheet.

  The frame 8 is cut out from the prepreg molded product. As a cutting method, for example, a laser beam, a water jet, or an apparatus using a blade, for example, a laser processing apparatus, a water jet processing apparatus, a resin NC processing apparatus, or the like can be used. The method for cutting out the frame 8 is not particularly limited.

  When this cutting is performed, for example, the bottom surface of the fixing portion may be curved so that the bottom surface of the fixing portion is satisfactorily seated, or the groove is formed so that the fixing thread is easily hooked on the upper surface of the fixing portion. Processing may be performed. Further, the frame 8 may be subjected to chamfering processing or barrel polishing processing for preventing cracking from each edge and removing burrs. In addition, for surface protection, coating may be performed with a member having a thickness that does not increase weight and hardness (for example, ceramic, glass, or a metal having corrosion resistance (by salt water)). . For the film formation, a physical vapor deposition technique (PVD: evaporation method or sputtering method or the like) or a chemical vapor deposition technique (CVD: CVD method) can be used.

  Thereafter, the guide ring 7 is fitted into the ring holding portion 8a of the completed frame 8 by using a normal method and fixed with an adhesive or the like. In addition, depending on the load of the fishing rod used and the type of fishing line, the guide ring is not necessarily required. The inner surface of the ring holding part may be polished to a mirror surface, or a surface process for laminating a hard member may be performed separately. It may be processed so that the fishing line can be easily guided.

  As described above, according to the present embodiment, the branch gap member 14 made of a resin material is in close contact with the joint surface of each of the laminated sheets 11, 12, 13 and sealed at the center of the branch point A of the frame 8. Thus, the force acting between the joint surfaces can be reduced. Furthermore, it is possible to prevent peeling or cracking that occurs between the joint surfaces of the laminated sheets due to the action of fishing line load or the bending of the rod.

Next, a first modification of the first embodiment will be described.
In the first embodiment described above, the branch gap member 14 made of only the resin member is inserted into the branch portion. However, as a first modification, as shown in FIG. A branch gap member 16 including the above may be used. The plurality of reinforcing fibers 15 are given strength in the width direction of the frame 8 by being inserted along the direction in which the branch gap member 16 extends.
Further, as a second modification, as shown in FIG. 7B, a prepreg 17 including reinforcing fibers 15 may be used as a branch gap member by being folded into a triangle in the fiber arrangement direction. Alternatively, the prepreg 17 may be used by being cut long and thin in the fiber arrangement direction.

Furthermore, as a third modified example, as shown in FIG. 7C, a prepreg 18 including the reinforcing fibers 15 may be rounded according to the size of the gap.
According to this modification, it is possible to provide a fishing line guide that has the same effect as that of the first embodiment described above, and further has increased strength with reinforcing fibers.

[Second Embodiment]
FIG. 8 is an enlarged view showing a branching point in the fishing line guide according to the second embodiment. FIG. 9 is a view for explaining press forming for forming a fishing line guide in the present embodiment. In the present embodiment, the same parts as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted.

The fishing line guide 31 of the present embodiment has a structure in which a gap 32 having the same shape is intentionally formed at the branching point A of the leg under a condition that satisfies design performance (manufacturing standard). As described above, even in the case of a fishing line guide that satisfies the performance, if there is a gap, the user may be regarded as having a gap as a defective product. Are intentionally formed to eliminate the presence or absence of voids.
As shown in FIG. 8, the branched portion A of the fishing line guide 31 is formed in a shape that matches the facing state of each surface of the three laminated sheets 11, 12, 13, in this embodiment, in a substantially triangular shape or a circular shape. An air gap 32 is provided. By providing this gap, the branching portion has a low rigidity, is easily deformed, easily follows the bending of the ridge, and is not easily damaged.

FIG. 9 illustrates the formation of the fishing line guide 31 that forms the gap 32.
Similarly to the first embodiment described above, the laminated sheets 11, 12, and 13 in which the prepregs are stacked are loaded into predetermined positions of the molds 21, 22, and 23 for press molding. Next, the molds 21, 22, and 23 are brought into contact with each other at predetermined positions as shown in FIG. At that time, the punching die 33 is inserted so that the convex portion (tip portion) of each mold is sandwiched between the opposing locations (branch locations). The punching die 33 is a rod member having a circular (cylindrical) cross section, and is made of, for example, metal. In a state where the punching die 33 is inserted, pressurization and thermal processing are performed by the dies 21, 22, and 23. In this heat treatment, the resin is melted and filled from each laminated sheet so as to fill the gap between the punching die 33 and the laminated sheets 11, 12, and 13.

  A prepreg molded product 20 similar to that shown in FIG. 6A is taken out from the cooled molds 21, 22, and 23. The punching die 33 is extracted from the thermoset prepreg molded product 20. Thereafter, similarly to the first embodiment, the frame is cut out from the prepreg molded product.

  According to the present embodiment, it is possible to provide the fishing line guide 31 in which a uniform gap is provided at the branch point. Therefore, there is no state in which the presence or absence of voids having different shapes at the branch location is eliminated, and it is possible to prevent a situation that is regarded as a defective product by the user. Moreover, since it is the space | gap of the uniform shape, it can be caught as a design which aimed at weight reduction. In addition, the standardized gap easily deforms because the branch portion has low rigidity, easily follows the bending of the ridge, and is not easily damaged.

[Modification of Second Embodiment]
As a modification, a mold member made of a triangular prism-shaped resin having a hollow inside may be used in place of the metal punching die 33. In addition, the resin material used for a formwork member selects the material which does not deform | transform or melt | dissolve in the case of heat-hardening with respect to a prepreg. It is also possible to use a thin metal having corrosion resistance against salt or the like. The formwork member is preferably a hollow triangular prism shape, but is not limited to this, and any other ring shape such as a hollow circle or an ellipse may be used as long as the shape is in contact with the laminated sheet. May be.
According to this modification, by using the mold member, the frame can be cut out without being drawn from the thermoset prepreg molded product. Thereby, a manufacturing process is simplified.

[Third Embodiment]
FIG. 10 is an enlarged view showing a branching point in the fishing line guide according to the second embodiment. In the present embodiment, members equivalent to those in the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted. In fishing rods that target small fish, since the load applied to the rod is relatively small, the fishing line guide is not required to have much strength and may be most demanded to be light.

  In the present embodiment, the laminated sheet (first fiber reinforced resin layer) and the laminated sheet 12 (second fiber reinforced resin layer) are separated from the branching point A under the ring holding part by two supporting leg parts (main leg part 8b, auxiliary leg). A fishing line guide 41 branched to a portion 8c) and connected to a fixing portion (not shown). The branch gap member 42 is assigned to the branch portion A during the thermosetting process for the laminated sheets 11 and 12 and is dissolved and fixed to the surfaces of the respective leg portions. The branch gap member 42 is made of the above-mentioned thermosetting resin or thermoplastic resin made of the same material as the fishing rod, and may include a plurality of reinforcing fibers. Moreover, you may utilize a prepreg.

According to the present embodiment, by providing the branch gap member 42 at the branch point of the support leg portion, it is possible to prevent the laminated sheets 11 and 12 from being torn or peeled off. Furthermore, it is suitable for a fishing line guide mounted on a fishing rod with a relatively small load for small fish, and further weight reduction can be realized.
In addition, although each embodiment mentioned above demonstrated the fishing line guide provided with the fixing part of two legs, it can be applied with respect to the guide which has a branch location, and the branch of the top guide attached to a tip as an other than this. The same effect can be applied to the location, and the same effect can be obtained.

  As described above, according to each embodiment of the present invention, it is possible to provide a fishing line guide suitable for a fishing rod that has been reduced in weight as the fishing rod manufacturing technology advances. That is, when a large number of fishing line guides having a metal frame are attached to a lighter fishing rod, not only the weight of the entire rod is increased, but also the weight balance of the entire fishing rod is deteriorated.

  This is a small size (compared to the main rod side) on the tip side of the rod, but a large number of fishing line guides are attached at close intervals. When looking from the weight balance of the rod itself, the tip of the rod tends to be heavier than a fishing rod with a conventional structure. It becomes difficult to handle. In a fishing rod using a spinning reel, for example, a throwing rod having a length of more than 4 m for throwing a device away from the beach, there is a demand to increase the flight distance as much as possible. Therefore, since the flying distance is influenced by the speed at which the rod tip swings out, along with the flexible flexibility of the fishing rod, the long throwing operation is greatly affected by the bending degree, weight reduction, and weight balance of the rod.

For such problems, by applying the fishing line guide to which each of the embodiments described above is applied, the weight of the entire rod is reduced, and the same throwing method as before without greatly changing the weight balance of the rod. With this, you can increase the speed at which the tip swings out.
Furthermore, the fishing line guide frame is made of a resin material similar to that of the fishing rod, so when it is fixed to the fishing rod, it deforms following the bending of the fishing rod. Thus, it is possible to achieve the desired degree of bending of the rod without impairing the flexible flexibility of the fishing rod.

In each of the embodiments described above, the first and second leg portions extend independently from the end portions of the ring holding portion (fishing line guide portion) 8a independently of each other. It is not limited. For example, the structure which extends independently from the edge part of the same location of the ring holding | maintenance part (fishing line guide part) 8a may be sufficient.
Furthermore, as shown in FIG. 12, the structure which one leg part branches and extends from the other leg part may be sufficient. For example, the second leg portion 8b is provided by branching from the middle of the first leg portion 8c extending from the ring holding portion (fishing line guide portion) 8a formed by the laminated sheet 11 and the laminated sheet 12. In this case, a branch point A is generated between the first leg portion 8c and the second leg portion 8b. Even in such a configuration, by applying the first to third embodiments described above, a fishing line guide in which a resin member is filled in a gap at a branching place or a uniform shaped gap is provided at a branching place. Can be provided.
