JP 2017-127248 A

An object of the present invention is to provide a fishing rod and a rod body which are tenacious and resistant to twisting and which can be lightened.

A fishing rod according to the present invention comprises a solid rod body, and the rod body blank comprises a solid body made of fiber-reinforced resin having the entire length of the blank and a sheet formed along the entire outer length of the solid body. A cylindrical main layer made of a prepreg having a shape, and two tape-like prepregs formed along the entire outer length of the main layer are spirally wound with a gap between them, and are wound so as to intersect each other. The main layer has a vertical fiber layer over the entire length of the blank in which the reinforcing fibers are along the direction of the center line of the rod body, and the vertical fiber layer at the rear end of the blank The number of turns of prepreg in the layer is greater than the number of turns of prepreg in the longitudinal fiber layer at the leading edge of the blank.

Reinforcement fibers along the direction of the center line of the rod body are called longitudinal fibers. The main layer of the blank of the solid-shaped fishing rod has a longitudinal fiber layer formed of longitudinal fiber prepreg (longitudinal fiber prepreg) over the entire length of the blank. Since the number of turns of the prepreg of the vertical fiber layer at the rear end of the blank is greater than the number of turns of the prepreg of the vertical fiber layer at the front end of the blank, the bending strength of the blank can be easily secured by the vertical fiber layer. In addition, the taper rate of the solid body does not need to be excessively increased, and the solid body can be made thinner.

In particular, the vertical fiber layer is composed of a plurality of vertical fiber prepreg layers formed by winding a plurality of sheet-like vertical fiber prepregs each having reinforcing fibers along the direction of the center line of the rod body, Each rear end portion of the plurality of longitudinal fiber prepreg layers is located at the rear end portion of the blank, each front end portion of the plurality of longitudinal fiber prepreg layers is located on the front side of the outer longitudinal fiber prepreg layer, and the plurality of longitudinal fibers It is preferable that the outermost longitudinal fiber prepreg layer positioned on the outermost side of the prepreg layers is formed over the entire length of the blank. By forming the vertical fiber layer from a plurality of vertical fiber prepreg layers in this way, the number of turns at the rear end of the vertical fiber layer can be easily made larger than that at the front end. Since the front ends of the outer longitudinal fiber prepreg layers are located closer to the front side, the outer longitudinal fiber prepreg layers can suppress the separation of the front ends of the inner longitudinal fiber prepreg layers.

Furthermore, the solid body has a front portion that expands rearward at a predetermined taper rate, and a rear portion that expands rearward at a taper rate smaller than the taper rate of the front portion or has a constant diameter. It is preferable to have By making the taper rate of the rear portion of the solid body smaller than that of the front portion, the weight of the solid body can be reduced. Then, the tension of the rod body can be set by the main layer, and in particular, the tension of the rear part of the rod body can be easily set by the main layer. Also, by providing a plurality of vertical fiber prepreg layers inside the outermost vertical fiber prepreg layer, the taper ratio of the rear portion of the blank can be gradually brought closer to the taper ratio of the front portion. Therefore, the longitudinal fiber prepreg having the length of the entire length of the main layer can be neatly wound.

Further, the fishing rod according to the present invention has a solid first rod body having a tip portion at the front end portion and a male joint portion at the rear end portion, and a male joint portion of the first rod body at the front end portion. A hollow second rod body having a detachably inserted female joint portion and a rod butt portion at the rear end portion, and the blank of the first rod body has the total length of the blank. A solid body made of fiber-reinforced resin, a tubular main layer made of sheet-shaped prepreg formed over the entire outer length of the solid body, and two tape-shaped prepregs formed over the outer length of the main layer. Cloth tape layers spirally wound with a space between each other and wound so as to cross each other, and the main layer is a vertical fiber layer in which the reinforcing fibers are along the direction of the center line of the rod body. over the entire length of the blank, and the number of turns of the prepreg of the longitudinal fiber layer at the rear end of the blank is greater than the number of turns of the prepreg of the longitudinal fiber layer at the front end of the blank.

A fishing rod with this configuration is composed of two rod bodies, a first rod body on the front side and a second rod body on the rear side. By making the first rod body on the front side solid, it is possible to produce a tenacious tone, and by making the second rod body on the rear side hollow, it is possible to prevent the fishing rod from becoming too heavy. can be made lighter.

In particular, the male joint portion is constituted by a predetermined length region of the rear end portion of the blank of the first rod body, and the male joint portion is provided with an auxiliary layer made of auxiliary prepreg outside the cloth tape layer. is preferred. By providing the auxiliary layer on the cloth tape layer, the dimensions of the outer peripheral surface of the male joint can be easily adjusted by polishing the auxiliary layer. Therefore, the male joint can be securely inserted into and fixed to the female joint.

Moreover, it is preferable that the first rod body has all the fishing line guides of the fishing rod, and the second rod body has the reel seat. The first rod body can produce a tenacious tone to the vicinity of the hand, and can produce a tone similar to a one-piece rod. Moreover, the weight of the fishing rod can be reduced by making the second rod body having the reel seat hollow. Furthermore, since the first rod body has all the fishing line guides, for example, the second rod body can be used by attaching the first rod body with other specifications. That is, the first rod body and the second rod body can be used in combination as appropriate.

Further, the rod body of the fishing rod according to the present invention is a solid rod body, and the rod body blank comprises a fiber-reinforced resin solid body having the total length of the blank and the outer total length of the solid body. A cylindrical main layer made of a sheet-shaped prepreg formed in the main layer, and two tape-shaped prepregs formed along the entire outer length of the main layer, each spirally wound with a gap and intersecting with each other The main layer has a vertical fiber layer along the entire length of the blank in which the reinforcing fibers are along the direction of the center line of the rod body, and the main layer has a longitudinal fiber layer over the entire length of the blank The number of turns of the prepreg of the longitudinal fiber layer at the end is greater than the number of turns of the prepreg of the longitudinal fiber layer at the front end of the blank.

As described above, a sticky tone can be secured by the solid body, and bending strength can be secured by the vertical fiber layer extending over the entire length of the main layer. By increasing the number of turns of the prepreg at the rear end of the vertical fiber layer, the taper rate of the solid body does not have to be excessively increased, the solid body can be made thinner, and the weight of the rod body can be reduced. Layers can ensure torsional strength.

<Cloth tape layer 32>
The cloth tape layer 32 is formed over the entire length of the outer peripheral surface of the main layer 31 . The cloth tape layer 32 presses the main layer 31 against the solid body 30 and presses the longitudinal fibers of the outer peripheral surface of the main layer 31 inward. The cloth tape layer 32 is formed over the entire length of the blank 10 . As shown in an enlarged perspective view of FIG. 4, the cloth tape layer 32 is formed by spirally winding first and second tape-shaped prepregs 61 and 62 with a gap therebetween and intersecting each other. It is formed by being wound on the

The first tape-shaped prepreg 61 is spirally wound around the outer peripheral surface of the solid body 30 while leaving a gap without overlapping. The pitch of the first tape-shaped prepregs 61 is arbitrary, and the interval between adjacent first tape-shaped prepregs 61 is arbitrary. It is larger than the width of the first tape-shaped prepreg 61 .

The second tape-shaped prepreg 62 is wound around the first tape-shaped prepreg 61 . The lead angles of the first tape-shaped prepreg 61 and the second tape-shaped prepreg 62 with respect to the direction of the center line of the solid body 30 are opposite to each other. The first tape-shaped prepreg 61 and the second tape-shaped prepreg 62 together form an X shape. Each lead angle is, for example, 45 degrees with respect to the centerline of the solid body 30 . As shown in FIG. 4, the intersecting direction of the woven cloth of the reinforcing fibers of the main layer 31 and the intersecting direction of the cloth tape layer 32 are different from each other and are in a mutually inclined relationship. The pitch of the second tape-shaped prepreg 62 is substantially the same as the pitch of the first tape-shaped prepreg 61 . The reinforcing fibers of the first and second tape-shaped prepregs 61 and 62 are continuous along the longitudinal direction of the respective prepregs 61 and 62 without interruption. The reinforcing fibers are, for example, carbon fibres.

A synthetic resin is impregnated between the reinforcing fibers. Therefore, the solid body 30, the main layer 31, and the cloth tape layer 32 contain synthetic resin in addition to reinforcing fibers. Although various kinds of synthetic resins may be impregnated, the synthetic resin of the solid body 30 and the synthetic resin of the prepregs 41, 42, 43 may be different from each other.

<Male side joint part 11>
The male joint portion 11 is formed by a predetermined length region of the rear end portion of the blank 10 . The length of the male side joint portion 11 is arbitrary, and is, for example, about several tens of millimeters. An auxiliary layer 33 is formed by winding an auxiliary prepreg 70 in a predetermined length region of the rear end portion of the blank 10 . The auxiliary prepreg 70 is wound outside the cloth tape layer 32 , and the auxiliary layer 33 covers the outside of the cloth tape layer 32 . The width of the auxiliary prepreg 70 corresponds to the length of the male joint portion 11 .

The fishing rod constructed as described above is composed of two rod bodies, a first solid rod body 1 on the front side and a second hollow rod body 2 on the rear side. Since the first rod body 1 on the front side is solid, a tenacious tone can be produced. In addition, since the second rod body 2 on the rear side is hollow, it is possible to prevent the fishing rod from becoming too heavy, and it is possible to reduce the weight of the fishing rod even though it is tenacious.

In particular, since the first rod body 1 constitutes the main part of the fishing rod and all the fishing line guides 3 of the fishing rod are provided on the first rod body 1, the butt part or the vicinity thereof can be provided with a tenacious tone. can be taken out easily. You can get a tone close to the so-called one-piece rod. Furthermore, since the first rod body 1 has all the fishing line guides 3, it is possible to attach the first rod body 1 of other specifications to the second rod body 2, for example. That is, the first rod body 1 and the second rod body 2 can be used in combination as appropriate. Moreover, since the second rod body 2 including the reel seat 4, the first grip portion 22, and the second grip portion 23 is hollow, the weight of the fishing rod can be reduced as compared with a one-piece rod. Since the female side joint portion 21 of the second rod body 2 is located inside the cylindrical reel seat 4, the male side joint portion 11 of the first rod body 1 is connected to the female side joint portion 21 of the second rod body 2. And the vibration is transmitted to the hand via the reel seat 4 . In addition, since the first rod body 1 extends to the position just in front of the hand holding the reel seat 4, it is possible to produce a condition in which the rod is bent greatly to the vicinity of the hand.

In addition, in the main part of the fishing rod, that is, in the first rod body 1 having a length exceeding half of the fishing rod, the main layer 31 is formed along the entire outer length of the solid body 30, so that the main layer 31 ensures bending strength. It is possible to make the solid body 30 thinner and lighter. In particular, the reinforcing fibers of the solid body 30 are vertical fibers, and the reinforcing fibers of the main layer 31 are all vertical fibers except for the woven fabric, so the bending strength of the blank 10 of the first rod body 1 is can be easily secured. In addition, by using carbon fibers for both the reinforcing fibers of the solid body 30 and the reinforcing fibers of the main layer 31 except for the woven fabric, it is possible to create a sticky yet tense tone.

Further, the front end portion 42a of the second prepreg 42 is located forward of the front end portion 41a of the first prepreg 41, and the front end portion 43a of the third prepreg 43 is located forward of the front end portion 42a of the second prepreg 42. Therefore, when the first rod body 1 is greatly bent, the second prepreg layer prevents the front end of the first prepreg layer from peeling, and the third prepreg layer prevents the front end of the second prepreg layer from peeling. be. By forming the outer prepreg longer toward the front in this way, the bending strength from the intermediate portion to the rear end portion of the first rod body 1 can be easily ensured without increasing the taper rate of the solid body 30. be able to.

Since the third prepreg layer, which is the outermost prepreg layer of the main layer 31, covers the entire length of the solid body 30, the solid body 30 is prevented from being exposed, and the solid body 30 at the front end of the main layer 31 is prevented from being exposed. Peeling can also be prevented. Furthermore, since the main layer 31 covers the entire length of the solid body 30, a smooth bending curve can be obtained. In particular, since the longitudinal fiber prepreg layer 35 of the third prepreg layer covers the entire length of the solid body 30, a smooth bending curve can be obtained and the bending strength of the blank 10 can be ensured. In addition, the vertical fiber layer of the main layer 31 is formed over the entire length, and the number of turns at the rear end of the vertical fiber layer is greater than the number of turns at the front end and is two or more plies. It can be made thinner and lighter, and the required bending strength can be ensured. Since the vertical fiber layer of the main layer 31 is composed of a plurality of vertical fiber prepreg layers formed by independently winding a plurality of vertical fiber prepregs, the winding of the vertical fiber layer at the rear end of the main layer 31 It is easy to make a large number of turns, and the strength can be easily secured by the main layer 31, and the weight can be reduced. However, the vertical fiber layer of the main layer 31 may be formed from one sheet of vertical fiber prepreg.

In the first rod body 1, the woven fabric prepreg layer 36 is formed over the entire length of the main layer 31 like a bandage, so cracks between longitudinal fibers of the main layer 31 can be suppressed. Since the woven fabric prepreg layer 36 is formed on the third prepreg layer, which is the outermost layer of the main layer 31, the woven fabric prepreg layer 36 prevents cracks that are likely to occur near the outer peripheral surface when the first rod body 1 is bent. can be effectively suppressed. In particular, since the reinforcing fibers of the woven fabric run along the direction of the center line of the first rod body 1 and the circumferential direction of the first rod body 1, it is possible to effectively suppress the occurrence of cracks between the fibers in the longitudinal direction. Since the cloth tape layer 32 strongly presses the longitudinal fiber prepreg layer 35 and the woven fabric prepreg layer 36 inward over the entire length, the woven fabric prepreg layer 36 is more effective in suppressing the occurrence of cracks.

In addition, since the vertical fiber prepreg layer 35 and the woven fabric prepreg layer 36 are formed by winding the third prepreg 43, which is a laminated sheet, the woven fabric of the reinforcing fibers can be easily spread over the entire length of the main layer. Can be rolled. In addition, by using the laminated sheet, the woven fabric prepreg layer 36 can be adjacent to the vertical fiber prepreg layer 35, and the occurrence of cracks in the vertical fiber prepreg layer 35 can be suppressed by the adjacent woven fabric prepreg layer 36. can. Moreover, when at least the rear portion of the laminated sheet is wound more than once and the number of turns is two or more plies, the two or more woven fabric prepreg layers 36 suppress the inward progress of cracks.

Furthermore, since the cloth tape layer 32 is formed over the entire length of the outer side of the main layer 31, the torsional strength of the first rod body 1 can be ensured. Since the male joint part 11 is provided with the auxiliary layer 33 outside the cloth tape layer 32, the dimensions of the outer peripheral surface of the male joint part 11 can be easily adjusted by polishing the auxiliary layer 33. be able to. Therefore, even if the cloth tape layer 32 is formed up to the rear end portion of the first rod body 1, the male side joint portion 11 can be securely inserted and fixed to the female side joint portion 21.例文帳に追加

In this embodiment, the third prepreg 43 is wound with the first sheet 51 on the outside, but the third prepreg 43 is wound with the second sheet 52 on the outside as shown in FIG. It may be rotated. In this case, the outer peripheral surface of the main layer 31 , that is, the outermost surface is entirely formed of the second sheet 52 , and the outer peripheral surface of the main layer 31 is composed of the woven fabric prepreg layer 36 . If the outer peripheral surface of the main layer 31 is a woven fabric prepreg layer 36, the inner vertical fiber prepreg layer 35 is covered with the woven fabric prepreg layer 36, thereby preventing the vertical fibers from being exposed to the outside.

Further, in the above-described embodiment, the taper rate of the solid body 30 is constant over the entire length, but the solid body 30 may have a variable taper rate. For example, as shown in FIG. 7, the solid body 30 may include a front portion 80 that expands rearward at a predetermined taper rate and a rear portion 81 that has a constant diameter. By making the rear part 81 of the solid body 30 straight with a constant diameter, the weight of the solid body 30 can be reduced, and the weight of the first rod body 1 can be further reduced. The taper rate of the rear part of the blank 10 can be adjusted by the main layer 31, and the tension of the first rod body 1, especially the tension of the rear part of the first rod body 1 can be easily set.

In the configuration of FIG. 7, the main layer 31 includes a first prepreg layer formed from the first prepreg 41, a second prepreg layer formed from the second prepreg 42, a third prepreg layer formed from the third prepreg 43, and a fourth prepreg layer formed from the fourth prepreg 44 . The first prepreg 41, the second prepreg 42 and the third prepreg 43 are longitudinal fiber prepregs, and the first prepreg layer, the second prepreg layer and the third prepreg layer are longitudinal fiber prepreg layers. The fourth prepreg 44 is a laminated sheet, and the fourth prepreg layer is the outermost prepreg layer of the main layer 31 . The fourth prepreg layer has a laminated structure of a longitudinal fiber prepreg layer formed from the first sheet 51 and a woven fabric prepreg layer formed from the second sheet 52 . In this embodiment, the vertical fiber prepreg layers of the first prepreg layer, the second prepreg layer, the third prepreg layer, and the fourth prepreg layer constitute the vertical fiber layers of the main layer 31 .

The fourth prepreg layer has a length that spans the entire length of the solid body 30 .

A front end portion 43 a of the third prepreg 43 is located forward of a front end portion 42 a of the second prepreg 42 . In this way, the front end portion 41a of the first prepreg 41, which is the innermost prepreg, is positioned near the boundary portion 82, and the front end portion 42a of the second prepreg 42 on the outer side is positioned forward of the boundary portion 82, The rear portion 81 of the blank 10 of the first rod body 1 can be easily tapered. In addition, since the outer prepreg is longer and the front end is located on the front side, the taper rate of the rear portion of the blank 10 can be gradually brought closer to the taper rate of the front portion, and the fourth prepreg 44 can be wound neatly. can be turned. The rear portion 81 of the solid body 30 may not have a straight shape, and the rear portion 81 of the solid body 30 may have a tapered shape that expands rearward at a taper rate smaller than that of the front portion 80. good too.

Although the vertical fiber prepreg layer and the woven fabric prepreg layer in the outermost prepreg layer were formed from laminated sheets, the vertical fiber prepreg layer and the woven fabric prepreg layer over the entire length of the main layer 31 were each separately formed from a single prepreg layer. may be formed. In that case, the longitudinal fiber prepreg layer and the woven fabric prepreg layer over the entire length of the main layer 31 are preferably adjacent to each other.

In addition, in the above embodiment, the male side joint portion 11 of the first rod body 1 is constituted by a predetermined length region of the rear end portion of the blank 10.
