Description

  The present invention relates to a fishing rod having a characteristic in a fixing structure of a fishing line guide for guiding a fishing line.

  In general, a fishing line guide for guiding a fishing line is attached to the fishing rod, and the fishing line inserted through the fishing line guide can be smoothly discharged and collected without being entangled with the fishing rod.

  These fishing line guides have a frame made of metal or synthetic resin, and with the legs provided on the frame placed on a fishing rod, a thread is wound around the frame to synthesize the winding part. It is fixed to the fishing rod by applying a resin adhesive.

  However, even when the fishing line guide is fixed to the fishing rod by the thread-like body and the adhesive as described above, there is a problem that the fishing line guide is loosened and its fixing position is shifted. Therefore, Patent Document 1 discloses a fishing line guide in which fine irregularities are formed on the upper surface of the leg portion in order to prevent loosening of the leg portion of the fishing line guide attached to the fishing rod.

JP 2000-139283 A

  However, since the frame of the fishing line guide disclosed in Patent Document 1 is made of metal, the compatibility (familiarity) with the synthetic resin adhesive is not sufficient. For this reason, even if the wound filaments can be prevented from being displaced by the fine irregularities on the upper surface of the leg portion, it is difficult to firmly perform the final fixing with the synthetic resin adhesive.

  The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a fishing rod in which legs of a fishing line guide are firmly attached.

  In order to solve the above problems, the present invention provides a fishing rod in which a fishing line guide having a leg portion made of fiber reinforced resin is attached to a rod, and the leg portion is formed on the upper surface of the leg portion of the fishing line guide. The reinforcing fiber of the fiber reinforced resin to be exposed is exposed, and the fishing line guide has the leg portion placed on the rod, and the thread-like body covers the upper surface of the leg portion so as to cover the upper surface. The reinforcing fiber exposed to the upper surface of the leg portion of the fishing line guide is in contact with the adhesive in that state. .

  According to the fishing rod of the above configuration, the reinforcing fiber exposed on the upper surface of the leg portion of the fishing line guide attached to the rod is covered with the adhesive (contacts with the adhesive), so that the reinforcing fiber constituting the leg portion of the fishing line guide The side surface of the fiber and the cut fiber protruding end are structurally firmly bonded to the adhesive. Therefore, the leg portion of the fishing line guide can be firmly attached and fixed to the rod, and the loosening of the leg portion can be effectively prevented. In addition, when the reinforcing fiber exposed on the upper surface of the leg portion of the fishing line guide is in contact with the filament wound around the upper surface of the leg portion, the exposed fiber protruding end is in contact with and engaged with the filament. Therefore, the attachment and fixing of the fishing line guide leg to the rod is further strengthened by the holding action by the thread-like body.

  Further, in the above configuration, the distal end of the upper surface of the leg portion of the fishing line guide is provided with a distal inclined surface that is inclined downward toward the distal end, and the reinforcing fibers exposed at the distal inclined surface are directed in a plurality of directions. It is preferable to extend. Moreover, the upper surface of the leg part of a fishing line guide has a side inclined surface which inclines downward toward the respective left and right side edges, and the reinforcing fibers exposed on the side inclined surface are directed in a plurality of directions. Preferably it extends. In this way, when the inclined surface is provided on the upper surface of the leg portion of the fishing line guide, all the layers of the fiber reinforced resin layer constituting the leg portion can be exposed on the surface (upper surface), and therefore the direction of the reinforcing fiber of each layer (For example, the long axis direction of the fishing rod, the oblique direction that forms a predetermined angle with respect to the long axis direction of the fishing rod) and the like, the reinforcing fibers exposed on the inclined surface can be extended in a plurality of directions. From any direction, the adhesive or thread can be engaged with the reinforcing fiber, and peeling of the adhesive or loosening of the thread can be effectively prevented. Further, if such inclined surfaces are provided on the left and right of the upper surface of the leg portion, the exposure directions of the reinforcing fibers exposed on the inclined surfaces (outwardly protruding directions) are inevitably opposite to each other on the left and right. The back and forth movement of the leg can be supported from both sides by the fiber. Therefore, it is possible to reliably prevent the leg portion from moving back and forth.

  ADVANTAGE OF THE INVENTION According to this invention, the fishing rod in which the leg part of a fishing line guide is attached firmly can be provided.

It is a principal part longitudinal cross-sectional view with the partially expanded view of the fishing rod of FIG. It is a principal part top view with the partially expanded view of the fishing rod of FIG. It is an enlarged plan view which shows the exposure direction of the reinforcing fiber of the leg part of the fishing line guide of the fishing rod of FIG.

Hereinafter, an embodiment of a fishing rod according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a main part with a partially enlarged view of a fishing rod 50 according to an embodiment of the present invention in which the fishing line guide 1 is attached to the rod 40. As shown in the figure, the fishing line guide 1 is formed by laminating fiber reinforced prepregs (hereinafter referred to as prepregs) in which reinforcing fibers are impregnated with a synthetic resin in the front-rear direction (or in the vertical direction as a result of the leg portions described later). And a frame 3 formed of a laminate of a plurality of fiber reinforced resin layers.

  The frame 3 includes a fixing portion 5 attached to the outer surface of the rod 40, a ring holding portion 7 to which a guide ring 6 having a fishing line insertion hole 13 (see FIG. 2) through which a fishing line is inserted, and a ring holding portion 7 And a support leg portion 8 that connects between the fixed portion 5 and the ring holding portion 7. The ring holding portion 7 is formed in a plate shape having a width in the left-right direction larger than the thickness in the axis O direction (front-rear direction). However, the thickness in the front-rear direction and the width in the left-right direction of the frame 3 may be the same, or the thickness in the front-rear direction may be larger.

  In the present embodiment, the ring holding portion 7 is formed by providing an opening (through hole) 7 a for holding the guide ring 6 in the frame portion of the support leg portion 8. Moreover, the fixing | fixed part 5 is a site | part (it is also called a leg part) fixed to the surface of the rod 40 in the lower end of the flame | frame 3, In this embodiment, plate shape (it extends in the front-back direction of the fishing line guide 1). It is formed as a leg part. When the fishing line guide 1 is attached to the rod 40, the fixing portion 5 as the leg portion extends in the axial length direction (the direction of the axis O) of the fishing rod 50, and the contact surface 19 on the back side thereof is the rod 40. For example, after winding the filament 32, the adhesive 34 is applied to the outside of the filament 32 (the filament 32 is wound around the collar 40 so as to cover the upper surface 5a of the fixing portion 5). Then, the adhesive 34 is applied) to fix the fixing region 30. In addition, the fixing | fixed part 5 can take various shapes, such as one leg and two legs. The filament 32 is made of multifilament (may be monofilament) and is made of synthetic resin fiber such as nylon or natural fiber such as cotton. The adhesive 34 is, for example, an epoxy-based, acrylic-based, urethane-based or the like synthetic resin adhesive, and is also impregnated into the thread-like body 32.

  The ring holding part 7 is a part for fastening the guide ring 6 so as to guide the fishing line in a state of being separated from the surface of the rod 40. The ring holding portion 7 is formed with the above-described opening 7a (see FIG. 2) for fitting and fixing the guide ring 6, and has a substantially circular outer shape as a whole. The guide ring 6 inserted into the opening 7a is formed in a ring shape, and is formed of a member having a small sliding resistance at the fishing line guide surface 6a, which is the inner peripheral surface thereof, such as titanium, SUS, ceramics, or the like. ing. The guide ring 6 is fitted and fixed to an opening 7 a formed in the ring holding portion 7 after the frame 3 is integrally formed by the prepreg.

  Further, the support leg portion 8 is a portion that connects the fixing portion 5 and the ring holding portion 7 so that the guide ring 6 is separated from the surface of the flange 40. The support leg portion 8 may be formed along the vertical direction X (see FIG. 2) when the fishing line guide 1 is viewed from the front (in the axial direction of the fishing rod), or is inclined with respect to the vertical direction X. You may form as follows.

  The frame 3 has at least one bent portion. In the present embodiment, a first bent portion (a bent portion that rises from the end portion of the fixed portion 5 toward the support leg portion) 10a is formed at the boundary portion between the fixed portion 5 and the support leg portion 8, and further, the support leg. A second bent portion 10b that is bent more gently than the first bent portion 10a is formed on the ring holding portion 7 side of the portion 8. When such bent portions 10a and 10b are formed on the frame 3, in particular, by forming the second bent portion 10b on the support leg portion 8, the bending angle by bending the entire frame is set stepwise. It is possible to improve the strength by dispersing the stress concentration.

  By the way, the frame 3 of the fishing line guide 1 of the present embodiment is formed by pressing or the like from a prepreg (a plate-like body after heat forming) in a state where a bent portion having the above-described configuration is formed in advance. However, at this time, it is formed to have a predetermined outer shape. In the present embodiment, as shown in FIG. 1, the support leg portion 8 rising from the end portion of the fixed portion 5 via the first bent portion 10a gradually becomes wider as it moves upward, and the guide ring 6 is attached. It is integrally connected to a substantially circular ring holding portion 7 in which an opening 7a to be attached is formed. The support leg 8 may be formed with an opening (thinning) 8a (see FIG. 2) in order to reduce the weight.

  Specifically, the frame 3 includes a plurality of prepregs in which a reinforcing fiber is impregnated with a synthetic resin as described above in order in the front-rear direction (in the direction of the axis O in FIG. 1; It is formed by stacking sheets. In this case, the prepreg is configured, for example, in a state in which reinforcing fibers such as carbon fiber, glass fiber, and Kepler are aligned in a predetermined direction, or in a knitted sheet shape, and a thermosetting resin (for example, epoxy Resin, phenol resin) or thermoplastic resin (for example, nylon) is impregnated as a matrix resin. In addition, although the flame | frame 3 is comprised by the some fiber reinforced resin layer, it may contain the reinforcement layer so that the above-mentioned bending part may be reinforced. Further, the number of prepregs to be overlapped (number of layers) and the configuration of individual prepregs are not particularly limited. However, as described above, the bent portions 10a and 10b are formed in the frame 3, and in use. In consideration of the load applied to the frame 3, the characteristics of the fishing rod to be mounted, the mounting portion, and the like, the type of prepreg and conditions for stacking are arbitrarily adjusted.

  More specifically, the frame 3 of the present embodiment has a laminated structure as shown in FIG. 3 at least at a portion of the fixing portion 5 (preferably the entire fixing portion 5 as described later). Since 5 has an inclined surface, in FIG. 3, the layers stacked one above the other are exposed on the surface. That is, the frame 3 (fixed portion 5) has an axial length direction fiber resin layer 21 in which reinforcing fibers are aligned along the axial length direction of the fishing rod and a crossing direction having a predetermined angle with respect to the axial length direction of the fishing rod. It has diagonal fiber resin layers 22a and 22b in which reinforcing fibers are aligned, and a woven fabric layer 23 in which reinforcing fibers are knitted. In particular, in the present embodiment, the frame 3 (fixed portion 5) is predetermined with respect to the woven fabric layer 23, the axial length direction fiber resin layer 21, and the axial length direction in order from the upper surface (front surface) to the lower surface (rear surface). (The inclination angle is arbitrary, but +15 to +75 degrees is preferable, more preferably +30 to +60 degrees), and is opposite to the first oblique fiber resin layer 22a and the oblique fiber resin layer 22a. Second oblique fiber resin layer 22a in an orientation (inclination angle is arbitrary, but is preferably -15 to -75 degrees, more preferably -30 to -60 degrees), and yet another second oblique fiber resin An eight-layer structure is formed by the layer 22 a, another first oblique fiber resin layer 22 a, and another woven fabric layer 23.

  In this way, when forming a fishing line guide made of fiber reinforced resin, when the frame itself is viewed from the front or plan, a prepreg is selected and laminated so that the reinforcing fibers are oriented in at least three directions. Is preferred. That is, by setting the direction of the reinforcing fibers to three or more directions, it is possible to form a fishing line guide that is efficient, lightweight, and excellent in strength.

  Further, it is beneficial to dispose the woven fabric layer 23 on the outermost layer of the frame 3 as in the above-described arrangement configuration of the prepreg. This is because the surface of the frame 3 is a part that is easily hit by other objects and is easily peeled off, and the reinforcing fibers are peeled off from the edge of the frame such as when the frame is bent by the tension of the fishing line during actual fishing. Since there is a possibility of breakage, by arranging a woven fabric layer in which reinforcing fibers are knitted in this surface region, it is possible to effectively prevent tearing and peeling of the reinforcing fibers, improving strength, And stabilization can be achieved.

  By disposing such a woven fabric layer 23, it is possible to prevent the reinforcing fibers from peeling and breaking more reliably, and to improve the strength and stabilize the strength. Further, the bent portions 10a and 10b can be relatively strengthened, and a fishing line guide that is light in weight and excellent in strength balance can be obtained. Of course, it is preferable that the mesh width of the woven fabric layer 23 is also smaller than the minimum width at the fixed portions 5 and the ring holding portion 7.

  Further, in the present embodiment, in the laminated structure as described above, the reinforcing fibers are exposed on the upper surface (surface) 5a of the fixing portion 5 as the leg portion of the fishing line guide 1, and the front end portion and the left and right sides of the upper surface 5a are exposed. By forming the inclined surfaces 15, 16, 16 on the side portions, all of the layers 23, 21, 22 a, 22 b, 22 b, 22 a, 21, 23 of the fiber reinforced resin layer constituting the fixing portion 5 are formed on the upper surface (surface ) Exposed at 5a. Moreover, since the directions of the reinforcing fibers of the layers 23, 21, 22a, 22b, 22b, 22a, 21, 23 are different as described above, the reinforcing fibers exposed at the inclined surfaces 15, 16, 16 are in a plurality of directions. It is in an extended state.

  Specifically, a tip-side inclined surface 15 that slopes downward toward the tip is provided at the tip of the upper surface 5a of the fixed portion 5 of the fishing line guide 1. Further, the upper surface 5a of the fixing portion 5 of the fishing line guide 1 has side inclined surfaces 16 and 16 that are inclined downward toward the respective left and right side edges. And these front end side inclined surface 15 and the side inclined surfaces 16 and 16 are formed continuously (the front end side inclined surface 15 is continuing to the left-right side surface side of the fixing | fixed part 5), and each inclined surface The widths of 15, 16, and 16 are gradually increased toward the front (in the direction opposite to the support legs 8). The tip side inclined surface 15 and the side inclined surfaces 16 and 16 may be formed at the time of frame molding or may be formed by polishing.

  The exposure of the reinforcing fibers on the upper surface (surface) 5a of the fixing portion 5 is achieved by polishing and roughening the surface (bottom surface, upper surface, side surface) of the fixing portion 5. By this roughening, the end portion 20 of the reinforcing fiber of the fiber reinforced resin constituting the fixing portion 5 is exposed (including the protrusion) on the upper surface (surface) 5a. In particular, at the uppermost surface, the end 20 of the cut fiber and the side surface of the continuous fiber are exposed by roughening the surface of the woven fabric layer 23. Further, the end portions 20 of the reinforcing fibers are exposed in all other layers appearing on the upper surface 5a. Then, these exposed reinforcing fibers come into contact with the adhesive 34 and the thread-like body 32 at the time of fixing described above, and are adhered and held by the adhesive 34 or locked to the thread-like body 32.

  In FIG. 4, the exposure direction (protrusion direction) of the reinforcing fibers exposed (including the protrusions) on the tip side inclined surface 15 and the side inclined surfaces 16 and 16 is indicated by arrows. As shown in the figure, the reinforcing fibers exposed at the tip side inclined surface 15 extend in a plurality of directions, and the reinforcing fibers exposed at the side inclined surfaces 16, 16 also extend in a plurality of directions. . Moreover, in this embodiment, since the inclined surfaces 16 and 16 are provided in the right and left both sides of the fixing | fixed part 5 in the laminated structure mentioned above, exposure of the reinforced fiber inevitably exposed by the inclined surfaces 16 and 16 like illustration is carried out. The directions (outward protruding directions) are opposite to each other on the left and right (the exposure direction is opposite on the left and right of the center line O1 in the same layer).

  As described above, according to the fishing rod 50 of the present embodiment, the reinforcing fiber exposed on the upper surface 5a of the fixing portion (leg portion) 5 of the fishing line guide 1 attached to the rod 40 is covered with the adhesive 34 (adhesion). Therefore, the side surfaces of the reinforcing fibers constituting the fixing portion 5 of the fishing line guide 1, the cut fiber protruding end 20, and the like are structurally and firmly coupled to the adhesive 34. Therefore, the fixing portion 5 of the fishing line guide 1 can be firmly attached and fixed to the rod 40, and loosening of the fixing portion 5 can be effectively prevented. Further, in the present embodiment in which the reinforcing fiber exposed on the upper surface 5 a of the fixed portion 5 of the fishing line guide 1 contacts the thread-like body 32 that covers the upper surface of the fixed portion and is wound, the exposed fiber protruding end 20 is formed on the thread-like body 32. Since they are bonded in a state of abutting engagement, the fixing action of the fishing line guide leg to the rod 40 is further strengthened by the holding action by the thread-like body 32.

  Further, in the present embodiment, the front end portion of the upper surface 5 a of the fixed portion 5 of the fishing line guide 1 is provided with a front end inclined surface 15 that is inclined downward toward the front end, and the reinforcing fiber exposed at the front end inclined surface 15. Are extending in a plurality of directions, and the upper surface 5a of the fixing portion 5 of the fishing line guide 1 has side inclined surfaces 16 and 16 that are inclined downward toward the left and right side edges thereof, The reinforcing fibers exposed at the side inclined surfaces 16 and 16 extend in a plurality of directions. As described above, when the inclined surfaces 15, 16, 16 are provided on the upper surface 5 a of the fixing portion 5 of the fishing line guide 1, each of the fiber reinforced resin layers 23, 21, 22 a, 22 b, 22 b, 22 a, constituting the fixing portion 5. Since all of 21 and 23 can be exposed to the upper surface 5a, the reinforcing fibers exposed at the inclined surfaces 15, 16, and 16 can be arranged in a plurality of directions by changing the directions of the reinforcing fibers of each layer as in the present embodiment. The adhesive 34 and the thread-like body 32 can be engaged with the reinforcing fiber from various directions, and the peeling of the adhesive 34 and the loosening of the thread-like body 32 can be effectively prevented. Further, since such inclined surfaces 15, 16, 16 are provided on the left and right of the upper surface 5 a of the fixing portion 5, the reinforcing fiber exposed direction (outward protrusion) is inevitably exposed on the inclined surfaces 15, 16, 16. (Direction) is opposite to each other on the left and right, and therefore, the back and forth movement of the fixing portion 5 can be supported from both sides by the fibers. Therefore, it is possible to reliably prevent the movement of the fixed portion 5 in the front-rear direction.
