Description

  The present invention relates to a fishing rod rod body formed by winding a prepreg into a cylindrical body.

The fishing rod body is made by aligning reinforcing fibers such as carbon fibers, winding a prepreg sheet formed by impregnating the aligned reinforcing fibers with a resin such as epoxy, and winding it around a mandrel having a predetermined tapered shape, In general, the wound cylindrical shape is formed by firing.
In contrast to the case where the prepreg sheet is used to form a casing, the reinforcing fiber is aligned in the circumferential direction, and the prepreg impregnated with the thermosetting resin is cut into a narrow tape shape to form a slit tape. There are some which form and form this casing by winding the slit tape in a spiral shape over the entire length of the casing.

JP 2000-198154 A (paragraph number [0020] and FIGS. 1 and 2)

The above-described conventional configuration is configured by winding a first main pattern configured by cutting a prepreg obtained by aligning reinforcing fiber groups along the circumferential direction of the ridge into a sheet shape as an inner layer, and as an intermediate layer, Three main patterns made by cutting a prepreg with reinforcing fiber groups aligned along the axial direction of the ridge are cut into a sheet shape, and the reinforcing fiber groups are aligned in the circumferential direction as an outer layer. A slit tape made by cutting the prepreg into a tape shape is formed by spirally winding the length corresponding to the entire length of the housing, and the fishing rod is composed of the inner layer, the intermediate layer, and the outer layer. There was something to do.
However, in this case, since the direction of the reinforcing fiber is only arranged in the axial direction or the circumferential direction, when these casings are formed on the swing bar, the strength is insufficient at the mating portion. There was a thing.
In other words, in the swing rod, the outer peripheral surface of the heel end of the heel side skeleton is the inner peripheral surface of the heel tip of the heel side skeleton while the heel side skeleton is pulled out from the butt end skeleton. The configuration is adopted in which the extended state of the tip side casing is maintained by being in pressure contact. In this case, the outer peripheral surface of the heel end portion of the heel side housing that is in pressure contact with each other is referred to as the mating portion.
Here, in the case where the reinforced fiber disposed in the mating portion is formed of a prepreg that is disposed only in the axial direction or in the circumferential direction, the mating portion is in the axial direction of the ridge. In some cases, sufficient strength against the shearing force acting from the direction of tilting cannot be exhibited, and resin peeling, cracking, or generation of cracks may be observed at the mating portion.

  An object of the present invention is to provide a fishing rod that eliminates the above-mentioned drawbacks and that allows the outer peripheral surface of the rod to have a predetermined conical shape.

〔Constitution〕
A characteristic configuration of the invention according to claim 1 is that a prepreg slit tape in which reinforcing fiber groups are aligned along the circumferential direction of the ridge is spirally wound around a mandrel over a length corresponding to the entire length of the skeleton. The inner layer and the outer layer are respectively configured by turning, and the intermediate layer located between the inner layer and the outer layer is formed of a prepreg in which reinforcing fibers are aligned along the axial direction of the rod. Consists of a main pattern cut to a length equivalent to the full length,
The wrapping reinforcement pattern is disposed further inside than the heel tip of the inner layer, and the wrapping reinforcement pattern is shorter in the axial direction than the main pattern and the reinforcing fiber group is disposed on the heel axis. Prepregs arranged in alignment along the fourth inclination angle, the length in the axial direction is shorter than the main pattern, and the reinforcing fiber group is symmetrical to the reinforcing fiber group of the prepreg and the saddle axis The prepregs that are aligned and arranged in a state where
A buttock reinforcement pattern is disposed outside the buttock end portion of the outer layer, the buttock reinforcement pattern is shorter in the axial direction than the main pattern, and the reinforcing fiber group is arranged with respect to the heel axis. A state in which the length of the prepreg arranged in alignment along the third inclination angle, the length in the axial direction is shorter than the main pattern, and the reinforcing fiber group is symmetric with respect to the reinforcing fiber group of the prepreg and the saddle axis The operation effect is as follows.

[Action]
That is, the length along the axial direction is shorter than that of the main pattern, and the prepreg in which the reinforcing fiber group is arranged so as to be inclined with respect to the vertical axis, and the length along the axial direction is shorter than that of the main pattern. And a wrapping reinforcement pattern and a buttock reinforcement pattern formed by superimposing the reinforcing fiber group and the prepreg that is arranged in a symmetric manner with respect to the reinforcing fiber group of the prepreg, Because it is arranged at the heel tip and butt end, both reinforcement patterns are applied to the shear force acting in a state where the heel side skeleton is pulled out from the heel side skeleton and inclined to the heel axis. On the other hand, a counter force is exhibited, and a resin peeling phenomenon or the like at the mating portion can be suppressed.
In addition, in the present invention, sufficient tension is applied to the tape by arranging the reinforcing fiber group in the circumferential direction and applying a slit tape having a narrow width with respect to the axial direction as the inner and outer layers. The slit tape can be wound around the mandrel, and the reinforcing fiber constituting the slit tape can be spirally continuous from the heel end to the butt end of the casing. Since the strength is sufficiently exhibited and the tape itself is narrow, it can be wound more easily than the case of winding a prepreg sheet.
Moreover, since the fibers are arranged in the circumferential direction, the reinforcing fibers aligned in the circumferential direction exert a counter-force to try to deform the cross section of the housing into an elliptical shape that spreads horizontally, To improve the shape retention of the cross section of the housing.
On the other hand, as the intermediate layer is wound from above the slit tape, the main pattern made of a prepreg sheet in which reinforcing fibers are aligned along the cocoon axis, it acts on the cocoon by the downward load acting on the tip. The resistance force against the tensile force and the like along the saddle axis direction caused by the bending moment is increased, and the folding of the scissors due to the bending can be avoided in advance.
As described above, since the slit tape has a short width along the axial direction of the ridge, it is not difficult to wind uniformly over the entire length like a sheet-like prepreg. The tape layer can be used to build the inner layer.

〔effect〕
As a result, a fishing rod along the desired conical shape can be produced, and a rod capable of suppressing the generation of voids and the peeling of the resin can be provided.

  The characteristic configuration of the invention according to claim 2 is characterized in that the intermediate layer includes a first main pattern obtained by cutting a prepreg in which reinforcing fibers are aligned along the axial direction of the ridge to a length corresponding to the entire length of the skeleton, The prepreg in which the reinforcing fibers are aligned along the axial direction of the second main pattern cut into a length corresponding to the entire length of the casing is polymerized, and the effect is as follows. It is as follows.

[Function and effect]
While exhibiting the effect with respect to the invention which concerns on Claim 1, there exist the following effects.
In other words, a double-layered main pattern is arranged as an intermediate layer, and the alignment direction of the reinforcing fibers of the main pattern is arranged along the saddle axis direction, so that the bending moment acting on the fishing rod when the fish hits the needle The tensile force along the heel axis direction is generated by the above, but when the reinforcing fiber arranged in the heel axis direction exerts a counter force against the tensile force and prevents damage of the heel, etc. Therefore, it is possible to increase the counter force, to increase the cross-sectional secondary moment with respect to the bending moment, and to improve the strength against bending.

  The characteristic configuration of the invention according to claim 3 is that an intermediate butt reinforcement pattern is disposed outside the butt end portion of the intermediate layer between the intermediate layer and the outer layer, A prepreg having reinforcing fiber groups arranged along the second inclination angle with respect to the saddle axis and having a shorter length in the axial direction than the main pattern, the reinforcing fiber group of the prepreg, and the saddle axis The reinforced prepregs are arranged in a symmetric state with respect to the main pattern, and the prepreg having a shorter length along the axial direction than the main pattern is overlapped, and its function and effect Is as follows.

[Function and effect]
That is, since the middle buttock reinforcement pattern is also arranged inside the outer layer, the direction inclined with respect to the axial direction of the middle buttock reinforcement pattern with respect to the shearing force propagating from the buttock end of the outer layer Since the reinforcing fibers aligned in the above exhibit the counteracting force, peeling of the reinforcing fibers, settling of the resin and the like can be prevented.

  The characteristic configuration of the invention according to claim 4 is that an inner buttock reinforcement pattern is arranged inside a buttock end portion of the inner layer, and the inner buttock reinforcement pattern is longer in the axial direction than the main pattern. A prepreg in which the length of the reinforcing fiber group is aligned along the first inclination angle with respect to the saddle axis, and the length of the reinforcing fiber group in the axial direction is shorter than that of the main pattern. The reinforced fiber group and the prepreg that are arranged so as to be symmetric with respect to the saddle axis are overlaid, and the effects thereof are as follows.

[Function and effect]
As described above, since the inner buttock reinforcement pattern is provided further inside the inner layer at the position of the buttock end of the casing, the inner buttock reinforcement pattern, the middle buttock reinforcement pattern is provided at the position of the buttock end of the casing. A reinforcement pattern and an outer buttock reinforcement pattern are arranged. Therefore, since the reinforcing pattern can be provided for each layer as well as the outer surface that is in contact with the mating pressure contact surface, it is possible to increase the resistance against shearing force and effectively prevent deformation of the heel.

As described above, the casing A is formed by winding each pattern around the mandrel 4 sequentially. Further, the inclination angle θ of the reinforcing fiber in each reinforcing pattern can be set in a range of 0 ° to 90 °, but is preferably set in a range of 45 ° to 80 °. Furthermore, the inclination angles from the first inclination angle θ ₁ to the fourth inclination angle θ ₄ may be set to the same angle, and the inclination angles may be set to different angles.

[Second Embodiment]
A method for manufacturing the casing A will be described. Although not shown, in the first embodiment, as the second stage, the first and second main patterns 2A and 2B are overlapped and wound, but in the second embodiment, as the intermediate layer Ab Only the first main pattern 2A may be wound. Other than this, the inner layer Aa, the outer layer Ac, the wound winding reinforcing pattern 5 and the buttock reinforcing pattern 6 are the same.

  That is, in the second embodiment, only the first main pattern 2A is applied as the intermediate layer Ab. As a result, the resistance to the tensile force in the intermediate layer Ab is lowered, but the weight of the bag can be reduced instead. In this case, it can be used for a slightly smaller kite for small fish compared to the kite shown in the first embodiment.

[Third Embodiment]
A method for manufacturing the casing A will be described. As shown in FIG. 3, as a first stage, the wound reinforcement pattern 5 and the first buttock reinforcement pattern 7 are wound around the mandrel 4, and the wound reinforcement pattern 5 and the first wound around the mandrel 4. The first slit tape 1 as the inner layer Aa is wound from above the buttock reinforcement pattern 7. As the second stage, the first main pattern 2A and the second main pattern 2B are wound as an intermediate layer Ab from above the wound first slit tape 1. The second buttock reinforcement pattern 8 is wound from above the second main pattern 2B. Further, as the third stage, the second slit tape 3 as the outer layer is wound from above the second main pattern 2B and the second buttock reinforcement pattern 8, and the third buttock reinforcement pattern 6 from above the second slit tape 3 is wound. Is to be wound.

That is, in the third embodiment, as the buttock reinforcement pattern, the first buttock reinforcement pattern 7 is arranged inside the first slit tape 1 and the second buttock reinforcement pattern 8 is replaced with the second main pattern 2B. The point arrange | positioned on the outer side differs from 1st Embodiment.
As a result, a buttock reinforcement pattern is provided for each layer, so that a reinforcement pattern can be provided for each layer as well as the outer surface that contacts the mating pressure contact surface, and the resistance to shearing force can be increased. And can effectively prevent deformation of the heel. Therefore, as a rod to which the third embodiment is applied, it can be applied when fishing a large fish compared to that of the second embodiment. Two buttocks reinforcement patterns exhibit a resistance against the shearing force, and can suppress deformation and the like at the mating portion B.

  In the third embodiment, the second buttock reinforcement pattern 8 is provided on the second main pattern 2B. However, the position where the second buttock reinforcement pattern 8 is provided is the first main pattern 2A. And the second main pattern 2B, or inside the first main pattern 2A. Moreover, you may provide in the above-mentioned three places inside the 1st main pattern 2A, between the 1st main pattern 2A and the 2nd main pattern 2B, and the 2nd main pattern 2B outside.

[Another implementation structure]
(1) The configuration of the third buttock reinforcement pattern 6 may be as follows.
That is, as the third buttock reinforcement pattern 6 described above, a prepreg formed by inclining the reinforcing fiber c group with respect to the saddle axis X is overlapped so that the reinforcing fiber c group intersects each other. Combined 6A was used.

On the other hand, in this other embodiment, after winding the above-described polymer 6A, as shown in FIG. 4, it is assumed that a plurality of resin protrusions 9 are provided on the polymer 6A. Although a method for forming the resin protrusion 9 is not shown in the figure, the surface of the polymer 6A for forming the resin protrusion 9 is covered with a mask member having a large number of through holes, and the protrusion is formed on the mask member. By spraying the formed paint using a spray coating method, the paint is attached to the surface of the polymer 6A through the through-holes of the mask member, and the protrusions 9 are formed. Since the formation part of the protrusion 9 is formed on the back side that does not protrude from the heel tip of the buttock side skeleton in a state where the heel side skeleton is pulled out from the buttock side skeleton, the appearance is hardly impaired.
By forming the projections 9 in this way, the surface of the heel end portion of the heel side housing does not adhere to the inner peripheral surface of the heel tip portion of the heel side housing, and the projections 9 By forming a gap between them, moisture can be retained in this gap portion.

Therefore, as if the surface of the heel end of the heel side skeleton is in close contact with the inner peripheral surface of the heel tip of the heel side skeleton, moisture enters the contact area and the moisture The interposition may increase the degree of adhesion and may cause a sticking phenomenon. When this sticking phenomenon occurs, the tip side rod body once pulled out cannot be returned to the buttock side rod body. However, since the projection 9 is formed here, only the projection 9 is By contacting the inner peripheral surface of the heel tip of the side skeleton, the entire surface is not bonded, and moisture is also interposed between the adjacent projections 9, so that the heel end of the heel side skeleton Does not act in the direction of increasing the degree of adhesion with the inner peripheral surface of the heel tip of the buttock side skeleton.
The protrusions 9 may be formed independently instead of the third buttock reinforcement pattern 6.

(2) The configuration of the third buttock reinforcement pattern 6 may be as follows.
That is, as the third buttock reinforcement pattern 6 described above, a polymer 6A obtained by superposing prepregs formed by inclining the reinforcing fibers c with respect to the saddle axis X so that the reinforcing fibers c intersect each other. Was used. An auxiliary pattern 6B as described below may be used in combination with the polymer 6A.

That is, as shown in FIG. 5C, the auxiliary pattern 6B is formed on a prepreg 6a formed by impregnating a reinforcing fiber c such as carbon fiber in the circumferential direction with a thermosetting resin such as epoxy. A prepreg 6a formed by impregnating a thermosetting resin such as epoxy with a cross-set of highly flexible fibers c such as nylon and polyester, and by aligning carbon fibers and the like in the circumferential direction. Is wound from above the polymer 6A so that is on the inside.
As shown in FIG. 6, the length of the auxiliary pattern 6B along the axial direction is shorter than that of the polymer 6A, and the auxiliary pattern 6B is wound so as to be positioned on the tip side of the polymer 6A.

Here, the arrangement state of the polymer 6A and the auxiliary pattern 6B will be described. That is, the polymer 6 </ b> A located inside is arranged with a length corresponding to the length of the mating portion B. On the other hand, the auxiliary pattern 6B is arranged at a position shorter than the polymer 6A and closer to the tip side. Thus, even if the polymer 6A is installed in a length corresponding to the mating portion B, the tip side housing 1 is made shorter than the buttocks side housing 2 because it is shorter than the length of the mating portion B. When the drawer operation is performed, the heel tips of the polymer 6A and the auxiliary pattern 6B do not protrude beyond the heel tip of the buttock side housing 2, and the aesthetics can be improved.
Moreover, since the polymer 6A is provided on the shoulder portion on the tip side of the mating portion B, the strength of this portion can be improved, and in the vicinity of the tip side end in the mating portion B of the tip side housing 1 It is possible to avoid the breakage of the soot that is said to be “breaking”.

The prepreg 6b located on the front side of the housing in the auxiliary pattern 6B will be described in detail. As shown in FIG. 5 (a), in the prepreg 6b, a highly flexible fiber c is crossed and the fiber c is shaped like a turtle. The shape to be arranged in As shown in FIG. 5 (b), since the resin impregnated in the fiber c is polished and scraped off, only the fiber is exposed on the surface, and a turtle-like concave portion is formed. Has been. Resin fibers such as nylon and polyester are used as the highly flexible fibers used here.
Therefore, even if the prepreg 6b is positioned on the surface of the mating portion B and is in pressure contact with the prepreg constituting the mating portion B on the other side, moisture is interposed due to the presence of the turtle-like concave portion. However, moisture only accumulates in the turtle-like recesses and does not act in the direction of strengthening the pressure contact state, and the adhering state of the mating portion is relaxed.
(3) The configuration of the present invention can be applied not only to a swing rod type mountain stream rod, rod, etc., but also to a side-by-side type or inlay joint type fishing rod.
