Description

The present invention relates to a fishing rod characterized by a fixing structure for fixing attachment parts such as a fishing line guide and a reel seat to a rod and a fishing line guide that constitutes the attachment parts.

2. Description of the Related Art Conventionally, fishing rods that are used with reels have parts such as fishing line guides and reel seats (hereinafter also referred to as attachment parts) fixed to the surface of the rod. When the fishing line guide is fixed to the rod, for example, as disclosed in Patent Document 1, the foot and the rod are mounted on the rod while the foot (fixed portion) of the fishing line guide is placed on the rod. First, the fishing line guide is tightly bound to the rod by winding the winding line over and then, in the tightly bound state, an adhesive synthetic resin agent is applied to the wound portion of the winding line to harden it. ing. In this case, it is possible to prevent the fixed part fixed on the rod from slipping off (displacement) in the axial direction by providing a pair of overhanging parts that protrude outward on both sides in the width direction of the foot part. is.

Further, the above-described fishing line guide is generally formed of a metal material. For example, Patent Document 2 discloses that the frame of the fishing line guide is integrally formed of fiber-reinforced resin. In such a fishing line guide, as described above, the leg is placed on the rod, and the winding line is wound around the leg and the rod. It can be fixed by applying it to the winding part of the winding thread.

Patent No. 4722189 JP 2012-75347 A

When the fishing line guides are fixed to the rod constituting the fishing rod at predetermined intervals in the axial direction, the fishing line guides fixed to the base side are of high height. In addition, the length of the leg of each fishing line guide in the axial direction is determined by the fact that the guide ring portion fixed to the frame receives a moment in various directions and a large force acts on the leg. , a certain length is ensured to prevent slippage.

However, as the axial length of the foot increases, the rigid portion on the rod also increases, and when the entire fishing rod bends, the stress acting on the foot increases, hindering flexibility. , causing damage to the fishing rod. For this reason, when the fishing line guide is fixed on the rod, it is preferable to shorten the axial length of the leg as much as possible. The strength of the raised proximal end is weakened, and it becomes easy to break, and the fixing strength of the foot cannot be secured sufficiently.

The present invention has been made with a focus on the above-described problems, and when fixing a fixed part of a fiber-reinforced resin attachment part (such as a fishing line guide) to a rod, the flexibility of the whole is not hindered. To provide a fishing rod whose fixing strength is sufficiently secured at a fixing portion, and a fishing line guide fixed to the fishing rod.

In order to achieve the above object, a fishing rod according to the present invention has a fiber-reinforced resin attachment part placed on a molded rod, and a thermosetting resin sheet is attached to a fixing portion of the attachment part. The mounting part is fixed to the pole and rod by winding and heating the member, and the sheet member is wound around the pole and rod so as to cover at least the upper surface of the fixing part, and the mounting part is heated. The component and the sheet member are characterized in that the same kind of matrix resin is used.

The sheet member used for fixing the fixing portion of the fiber-reinforced resin attachment part to the rod and rod is wound around the rod and rod so as to cover at least the upper surface of the fixing part. Since the matrix resin of the member is the same type, the adhesiveness (improvement in fixing strength) of the upper surface of the fixing portion can be improved during heating, and the fixing strength of the attachment part can be ensured. As a result, the length of the fixed portion of the attachment part can be shortened, the rigidity of the rod can be reduced, and the flexibility of the fishing rod can be improved and damage can be prevented. The fixed portion may be configured to be fixed in a state in which the upper and lower surfaces are sandwiched by the sheet member, and the sheet member may be composed of one sheet, or may be composed of a plurality of sheets. Also good.

ADVANTAGE OF THE INVENTION According to the present invention, when the fixing part of the attachment part made of fiber-reinforced resin is fixed to the rod, the fishing rod does not hinder the flexibility of the whole and the fixing strength of the fixing part is sufficiently secured; A fishing line guide is obtained which is fixed to the fishing rod.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the fishing rod which concerns on this invention is concretely described, referring an accompanying drawing.
FIG. 1 is a diagram showing one embodiment of a fishing rod according to the present invention. The fishing rod 1 of this embodiment includes a base rod 3, a middle rod 5 and a tip rod 7 (each rod is also referred to as a rod), and each rod is jointed in parallel (each rod is The joint method of the rod may be a draw-out type, spigot joint type, or the like). Further, the fishing rod 1 of the present embodiment is provided with a reel seat 9 on the base rod 3, and the base rod 3, the middle rod 5 and the tip rod 7 are fed from a reel R attached to the reel seat 9. A line guide is mounted in place to guide the line that is being pulled. In FIG. 1, the fishing line guide provided on the base rod 3 is indicated by 10A, the fishing line guide provided on the middle rod 5 is indicated by 10B, and the fishing line guide provided on the tip rod 7 is indicated by 10C. A top guide 10D is attached to the tip of the tip rod 7. As shown in FIG. These fishing line guides 10A to 10C and reel seat 9 constitute attachment parts fixed to the surface (outer peripheral surface) of the rod.

The base rod 3, the middle rod 5, and the tip rod 7 are preferably made of tubular bodies made of fiber-reinforced resin. A fiber-reinforced resin prepreg (prepreg sheet) impregnated with a flexible synthetic resin is wound around a metal core, subjected to a heating process, and then decored to form a tubular shape of a predetermined size according to a standard method. In addition, each rod can be formed in various ways, such as forming a solid shape or joining a tubular body to a solid core material (for example, a superelastic alloy wire or a superelastic resin material). is possible.

The rod and rod configured as described above have their outer surfaces subjected to a surface treatment such as painting, and the mounting parts described above are attached to the rods in a surface-treated state. Hereinafter, the fixing structure of the attachment part of the present embodiment will be described by exemplifying the fishing line guide 10B fixed to the middle rod 5. As shown in FIG.
2 and 3 are diagrams showing the configuration of the fishing line guide 10B, where FIG. 2 is a side view and FIG. 3 is a front view.

The fishing line guide 10B is formed in a plate shape from a fiber-reinforced resin material in which reinforcing fibers are impregnated with a synthetic resin. In the present embodiment, the matrix resin constituting the fiber-reinforced resin material is, for example, a thermosetting resin such as urea resin, melamine resin, phenol resin, epoxy resin, unsaturated polyester resin, alkyd resin, urethane resin, or the like. By impregnating any reinforcing fiber such as organic fiber, carbon fiber, or glass fiber with the thermosetting resin, the fiber reinforced resin material is configured, and the fiber reinforced resin material is heat-molded A body of a fishing line guide is formed.

The fishing line guide 10B includes a fixing portion (foot portion) 11 fixed to the surface of the rod (middle rod) 5, a ring holding portion 12 to which a guide ring 12a through which the fishing line is inserted, and a ring holding portion 12. A supporting leg portion 15 that connects with the fixed portion 11 is provided.

The fixed portion 11 extends in the axial direction and is fixed by a sheet member wound around the rod 5 so as to cover the upper and lower surfaces of the fixed portion 11 (the configuration of the sheet member will be described later). Note that the fixed portion 11 can have various shapes such as one-legged and two-legged.

The ring holding portion 12 is a portion to which a guide ring 12a is fixed so as to guide the fishing line while being separated from the surface of the rod. The ring holding portion 12 is formed with an opening 12b into which the guide ring 12a is fitted and fixed, and has a substantially circular (or substantially elliptical) outer shape as a whole. The guide ring 12a fitted into the opening 12b has a ring shape and is made of a member with low sliding resistance, such as titanium, aluminum, SUS, or ceramics. The guide ring 12a is fitted and fixed in the opening 12ba of the ring holding portion after the main body of the fishing line guide is formed of the fiber-reinforced resin material described above.

The supporting leg portion 15 is a portion that connects the fixing portion 11 and the ring holding portion 12 so as to separate the guide ring 12a from the surface of the rod, and defines the height H of the fishing line guide. The height H of the fishing line guide is defined by the length from the surface of the rod (back surface of the fixing portion 11) to the upper end of the ring holding portion 12, as shown in FIGS.

The fixed portion 11 is bent in the axial direction at the lower end position of the supporting leg portion 15 and has a constant length L in the axial direction. Here, the length L of the fixing portion in the axial direction is defined by the length from the position P where the supporting leg portion 15 rises from the fixing portion 11 to the tip position P1 of the fixing portion.

In the present invention, the fixing structure of the fixing part 11 to the rod makes it possible to shorten the length L of the fixing part 11 with respect to the height H of the fishing line guide. The length of the fixing part 11 is shortened in spite of the large shape), and stress concentration applied to the guide fixing part when the rod is bent is reduced.

The fixing structure of this embodiment will be described below with reference to FIGS. 2 to 4. FIG.
In this embodiment, the fixed portion 11 of the fishing line guide is fixed by two sheet members. Specifically, first, a thermosetting resin sheet member (first sheet member) 20A is wound around the rod 5, and the fixed portion 11 of the fishing line guide is placed thereon. Then, a thermosetting resin sheet member (second sheet member) 20B is wound thereon, fixed with a tightening tape (not shown), and placed in a heating furnace in that state for heat treatment. .

Both the first sheet member 20A and the second sheet member 20B are configured as prepreg sheets in which reinforcing fibers are impregnated with a thermosetting resin as a matrix. The same kind of material as the matrix resin that constitutes is used.

Although the first sheet member 20A is wound once in the drawing, the number of turns and the thickness are not limited. For example, the first sheet member 20</b>A may be cut into one ply or less and placed on the rod 5 , or may be cut into one ply or more and wound around the rod 5 . In this case, if two or more plies are wound around the rod, the weight increases and the winding work becomes difficult, so the number of windings is preferably two or less.

A second sheet member 20B is further wound around the fixing portion 11 placed on the first sheet member 20A. The second sheet member 20B is wound by one or more plies so as to cover all the already wound (or placed) first sheet members 20A. By covering the entire first sheet member 20A with the second sheet member 20B in this manner, the fixing portion 11 can be stably held between the first sheet member 20A and the second sheet member 20B. , the fixing strength can be improved.

The number of turns and the thickness of the second sheet member 20B are not particularly limited, either, but it is preferable that the number of plies is two or less in consideration of weight reduction and easiness of the winding work. Moreover, the sheet member may be wound so as to cover only the upper surface side of the fixed portion 11 . That is, when the resin flows into the lower surface side of the fixing portion 11 (between the lower surface of the fixing portion 11 and the pole and rod), the first sheet member 20A may not be arranged.

The first sheet member 20A and the second sheet member 20B may be composed of a resin sheet using a thermosetting resin as a base material. and workability (the resin sheet is likely to be deformed and damaged during work), it is preferable to use a prepreg sheet in which reinforcing fibers are impregnated with a synthetic resin. When the sheet members 20A and 20B are made of prepreg sheets, the orientation direction of the reinforcing fibers is not particularly limited. It is preferable to include reinforcing fibers arranged in an oblique direction (for example, arranged at an angle of 45° with respect to the axial direction X). In other words, the fishing line guide receives a moment in various directions from the fishing line when casting or when a fish is caught, but since the reinforcing fibers are arranged in an oblique direction, stress acts in various directions. However, it is possible to improve the fixing strength.
The reinforcing fibers may be aligned in one direction, may be woven in a plain weave, or may have a structure in which a plurality of layers are laminated.

As described above, if the fixing portion 11 can be stably fixed in a state of being sandwiched between the sheet members 20A and 20B (a state in which the upper and lower surfaces of the fixing portions are covered), the configuration of the sheet members 20A and 20B can be appropriately modified. is possible.

As described above, the fishing rod to which the fixing portion 11 is fixed is placed in the heating furnace and subjected to heat treatment. At this time, when the sheet members 20A and 20B reach a predetermined curing temperature as the temperature of the heating furnace rises, the respective thermosetting resins are once liquefied, and thereafter the curing reaction proceeds. If the fixing part 11 and the fixing part 11 are made of the same resin material, the wettability (affinity) between the liquid and the fixing part is good, and the liquid easily flows into the irregularities on the surface of the fixing part without gaps. Effect) and adhesiveness (fixing force) is improved. Further, since the sheet members 20A and 20B and the fixed portion 11 have the same matrix resin, the intermolecular interaction is enhanced, the chemical adhesiveness is improved, and the fixing strength is increased.

By using the fixing structure as described above, the fishing line guides 10A to 10D that are attached and fixed to the entire fishing rod can all be improved in fixing strength at the fixing portion, and the axial length direction of the fixing portion 11 can be improved. It is possible to shorten the length L. Specifically, the result of comparison between a fishing line guide fixed by a conventional fixing structure (conventional example 1) and a fishing line guide fixed by the above-described fixing structure (Examples 1 and 2) will be described.
The fishing line guides of Examples 1 and 2 shown in Table 1 below and the fishing line guide of Conventional Example 1 are made of the same fiber-reinforced resin material, and Conventional Example 1 is fixed to the rod of a fishing rod. The part is placed and wound with a thread, and a synthetic resin agent is applied and hardened (conventional fixed structure). In both Examples 1 and 2, a prepreg sheet impregnated with the same synthetic resin material as the fishing line guide is fixed to the rod of the fishing rod having the same structure so as to cover the fixed portion. Specifically, a single sheet member in which reinforcing fibers are arranged in an oblique direction is double-wound at the fixing portion by 1.5 turns (see FIG. 9). Similarly, the fixed part is placed on the rod and fixed so as to cover the upper surface side.

In Conventional Example 1, a fiber-reinforced resin fishing line guide manufactured and sold by the applicant is fixed to a fishing rod. In order to obtain the required fixing strength, the length L of the fixing portion is formed longer than in the first and second embodiments of the present invention. In Example 1, the fishing line guides made of the same fiber-reinforced resin and having the same height are fixed at the same position under the condition that the fixing portion of each fishing line guide does not come off or break ( It is a specification attached under a limit condition), and Example 2 is a condition that has a certain amount of extra force (a condition that provides sufficient fixing strength and does not hinder the flexibility of the fishing rod; use of a guide condition).

As is clear from this result, when fixing the fishing line guide made of fiber-reinforced resin to the rod, by covering the upper surface of the fixed part with a prepreg sheet made of the same synthetic resin material, during heating and curing, The affinity with the fixed portion is improved, the fixing force is improved, and the length L of the fixed portion 11 of the fishing line guide can be shortened. That is, even with a relatively large (high H) fishing line guide on which a large moment acts, the length L of the fixed portion can be shortened (the ratio of L/H can be reduced). It is possible to alleviate the inhibition of bending. Specifically, according to the fixing structure of the present embodiment, the plurality of fishing line guides fixed to the rod of the fishing rod can be fixed to the fishing rod with a smaller L/H ratio than in the conventional fixing structure. Even if a fishing line guide with (L/H) of 30% or less is included among a large number of fishing line guides used, it is possible to ensure sufficient fixing strength for the fishing line guide. As a result, stress concentration at the fixed portion can be reduced, and damage to the fishing rod can be prevented, and bending of the fishing rod can be made smooth.

In addition, Table 2 below shows an example of specifications of a conventional general metal (titanium) bobbin fixed type fishing line guide (fishing line guide in practice).
The fishing line guide of Conventional Example 2 shown in Table 2 is composed of a titanium frame with a relatively low height H, and the fishing line guide of Conventional Example 3 is formed with a relatively high height H. It is constructed with a titanium frame. In general commercially available metal fishing line guides, the axial length L of the fixed part is formed long so as to ensure sufficient fixing strength. , the greater the height H, the greater the axial length of the fixing portion.

FIG. 5 shows the relationship between the axial length L of the fixing portion and the height H of the fishing line guide for the conventional fishing line guides (conventional examples 1 to 3) and the fishing line guide of the present embodiment (examples 1 and 2). is a graph showing
As shown in the graph of FIG. 5, in the fixing structure of the present invention, even if the height H of the fishing line guide increases, the axial length L of the fixing portion can be shortened (reduced ratio of L/H). It is possible to smooth the bending of the fishing rod while maintaining the fixing strength of all the fishing line guides attached and fixed to the fishing rod.

In this case, considering the fishing line guide fixed on the tip side, the minimum guide height H is required to be about 5 mm, and the axial length L of the fixed portion is determined by the length of the fixed portion when winding the fixing sheet member. Considering workability, etc., it is preferable to secure at least about 3 mm. Therefore, when the fixing structure of the present invention is used, the specifications of the fishing line guides fixed to the respective rods are as shown in the graph of FIG. It is also possible to use fishing line guides that are fixed in position and that satisfy L ≤ 0.24H + 2.12, which is a condition that does not affect flexibility (conditions that are substantially below the mass production conditions described above). According to a fishing rod to which a fishing line guide made of fiber-reinforced resin that satisfies such conditions is fixed, it is possible to sufficiently maintain the fixing strength of the fishing line guide and smooth the bending of the fishing rod as a whole.

The fixing portion 11 of the fishing line guide described above can be appropriately modified.
As shown in FIG. 2, it is preferable to form a tapered portion 11a on the distal end side of the fixing portion 11, the thickness of which gradually decreases toward the distal end side. By forming such a taper 11a, it is possible to suppress a decrease in the rigidity of the rod due to the fixed portion, and by winding the sheet members 20A and 20B around the upper and lower surfaces of the fixed portion 11, the fixed portion can be The force applied can be effectively received by the sheet member, and damage to the fishing line guide can be prevented.

In this case, if the length of the taper 11a is too long, the fixing strength becomes weak, and if the length of the taper 11a is too short, it becomes impossible to effectively suppress the deterioration of the rigidity of the rod and rod. It is preferably formed in the range of 25 to 75%, more preferably 32 to 65% of the height L.

In addition, it is preferable that the fixed portion 11 is subjected to a surface treatment that enhances the anchor effect in the axial direction. For example, the surface of the fixing portion 11 is roughened, unevenness is formed, or a depression (concave portion) is formed in the width direction so that the fixing portion is difficult to come off in the axial direction. enters, the anchor effect is enhanced, and it is possible to make it difficult to pull out the fishing line guide.

Such surface treatment may be performed on the entire surface of the fixed portion, but the range between the position of the tip of the fixed portion 11 and the position of 25% and 40% of the length L of the fixed portion By forming it inside, it is possible to efficiently improve the adhesiveness and make it difficult to come off.

Further, in the fishing line guide having the above-described configuration, the base end region of the fixed portion 11 (as shown in FIG. 2, the range L2 from the raised position P of the support leg to the position P2 of at least 1.8 mm toward the tip position) ) is subjected to a large bending stress. This bending stress is caused by the fishing line passing through the guide ring.

Therefore, in the range L2 described above, it is preferable to increase the strength by increasing the thickness of the fixing portion 11 . However, if the wall thickness of this portion is increased, when the sheet member 20B is wound on the upper surface of the fixed portion, the gap between the two sides of the sheet member 20B becomes large, and the resin becomes unstable, resulting in insufficient fixing force. (Refer to FIG. 4(a); it is deformed for clarity).

In this embodiment, chamfers 11c are formed on both sides in the width direction of the upper surface of the fixing portion 11 to reduce the gap (see FIG. 4B). In order to prevent the strength from decreasing, chamfering is formed on the front side of the range L2 to prevent the strength from decreasing on the base end side (increase the thickness). That is, according to such a configuration, it is possible to effectively prevent breakage, breakage, etc. between the supporting leg portion and the fixed portion without lowering the fixing strength.

7 and 8 are diagrams showing modifications of the sheet member for fixing the fixing portion of the fishing line guide.
In this embodiment, one prepreg sheet 20 impregnated with the same matrix resin as the matrix resin of the fishing line guide made of fiber-reinforced resin covers the upper and lower surfaces of the fixing portion 11 of the fishing line guide 1 .

Specifically, the prepreg sheet 20 is wound around the rod 5, the fixed portion 11 of the fishing line guide is placed, the prepreg sheet 20 is wound as it is, and is wound on the upper surface of the fixed portion 11, and in this state, the The prepreg sheet 20 is fixed with a tightening tape (not shown) from above and heat-treated. In this case, as long as one prepreg sheet can be wound so as to cover the upper and lower surfaces of the fixing portion 11, the number of turns of the prepreg sheet and the winding start position are arbitrary. Since a prepreg sheet is sufficient, workability can be improved.

Further, when fixing the fixing part 11 with one sheet member (prepreg sheet 20), for example, as shown in FIG. can be In such a configuration, it is preferable to wind the sheet member so that the upper surface of the fixed portion 11 is doubled (approximately 1.5 turns) so that the resin can easily flow into the lower surface side of the fixed portion 11 . . Furthermore, when a single sheet member is wound, the fixed portion may be wound three or more times. According to the fixing method as shown in FIG. 9, the fixing part is placed on the rod and the winding work is performed, so that workability can be improved.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified in various ways.

In the above-described embodiment, the fishing line guide was exemplified as the attachment part, but the attachment part is the reel seat 9 shown in FIG. 1 formed of fiber reinforced resin. It is possible to apply the method. Further, regarding the sheet member for fixing the fixing member, as long as it is arranged so as to cover the upper and lower surfaces of the fixing member, there is no limitation in the winding method or the configuration of the sheet member. is not limited as long as it is of the same kind as the matrix resin of the mounting part.
