Description

The front head is fine and has a fishing rod with the front head

The present invention relates to a front fine crucible formed by a combination of a metal and a fiber-reinforced resin, and a fishing rod having the front fine crucible.

In recent years, the fishing rod is formed of a fiber-reinforced resin containing reinforcing fibers, and the bending stiffness and/or torsional rigidity are improved, and the diameter and weight of the fishing rod are increased, and the operation becomes easy. In addition, the diameter of the fishing rod is reduced, and the load is greatly applied to the steamed bread due to the fish species, and the balance design of the strength of the fishing rod becomes difficult. Moreover, in the case where the hoe is still wound by the reel in a state where the fishing line is wound, or a local load is applied by putting the fishing rod, a top guide portion or The accident of the broken tip.

For this reason, for example, as proposed in Patent Document 1, a fishing rod having a tapered and uniform tapered metal pipe as a tip is proposed as a means for improving the strength of the front fine. Further, in this proposal, a technique of performing surface treatment by winding a corrosion-resistant coating film or a prepreg on the surface of a metal pipe is described. Of course, by metal materials In the formed fishing rod, a solid structure of the front fine sputum is also circulated.

[Patent Document 1]: Japanese Patent Laid-Open Publication No. 53-134686

In the aforementioned Patent Document 1, the metal pipe is subjected to tapered processing by swaging processing. Further, it is described that when this method is used, since the tip portion is thickened, it is adjusted by polishing to reduce the thickness. Further, a configuration manufactured by performing roll processing or tube processing on a metal plate has also been proposed.

However, even if it has flexibility due to the adjustment of the wall thickness, since the front fineness is uniformly hollow, the deflection of the special scorpion like a fish species, such as a squid or a green scorpion, is different. When the fishing rod is required, there is no versatility by thickness adjustment alone, and it is not a satisfactory structure even if it is easy to apply. In addition, in the case of the squid, it is not possible to use a metal tube. If it is seen from the deflection of the entire fishing rod, it is necessary to connect it to the resin in the middle. However, Patent Document 1 does not provide any Technology.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a fishing rod which is lightweight and has sufficient rigidity and which is capable of flexibly deflecting the fish bite and which is easy to distinguish from the fish hook.

In order to achieve the above object, the present invention is a front end fine crucible for use on a tip end of a fishing rod, comprising: a cylindrical tip end holding portion formed of a fiber-reinforced resin material; formed of a metal material and having at least The solid portion of any length placed on the side of the boring head and the hollow portion of any length adjacent to the solid portion are partially changed in the longitudinal direction of the hollow portion to change the wall thickness, and the rigidity is partially changed. The tip portion is formed by any one of a metal material or a fiber-reinforced resin material, and the joint portion between the tip end portion and the tip end holding portion is joined.

Moreover, the present invention is a fishing rod having a front fine structure composed of the foregoing configuration.

According to the present invention, it is possible to provide a fishing rod which is lightweight and has sufficient rigidity and which is excellent in the sensitivity to withstand the fish bite, and the fish hook is easy to distinguish the head fine and the fishing rod having the front fine.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1(a) is a view showing the overall appearance of the fishing rod according to the first embodiment, Fig. 1(b) is a cross-sectional view showing the material of the front fine layer before processing, and Fig. 1(c) is a front view showing A diagram of the cross-sectional structure of the fine section. Fig. 2(a) is a cross-sectional view showing another example of the material of the front fine layer before processing, and Fig. 2(b) is a view showing the cross-sectional structure of the front fine portion. In the following description, the fishing rod of the present embodiment has been described as an example of a plurality of knots that are divided into a plurality of roots and joined by a joint type or a telescopic type, and is a single knot. However, the fishing rod can be similarly applied to The hammer head is provided with a so-called single knot of the tip portion of the structure of the present embodiment.

As shown in Fig. 1(a), the fishing rod 1 joins the front fine head 2, the second jaw 3, and the main jaw 4 from the side of the head to form a fishing rod. The front fine tube 2 of the present embodiment is constituted by a member made of a metal tip. The tip portion 2a is joined to the tip portion 2a, and a resin sheet in which a fiber-reinforced resin is impregnated with reinforcing fibers such as carbon, that is, a resin-made tip holding portion 2b of a so-called prepreg is used.

As shown in Fig. 1(c), the tip end portion 2a of the metal tip is formed by a solid portion (solid) made of metal on the distal end side and a hollow portion (so-called tubular) 6b. As shown in Fig. 1(b), the tip end portion 2a of the present embodiment is formed by, for example, a tipping material 5 having a slender cover shape (bottom portion 5a and tube portion 5b) made of a titanium alloy. Fine tapered processing to stretch it. Further, in FIG. 1(b), although the cover-shaped tip material is shown, as shown in FIG. 2(a), the swaging material 7 in the shape of a cylinder (tube) may be used by swaging. The tapered shape is processed, and as shown in Fig. 2(b), it is elongated into a tube shape.

Further, even if the tubular tip material 7 is used, the shape of the tube of the thin tip portion can be broken by the tapered processing to form a solid portion. Further, the filling member may be partially inserted into the front end of the hollow structure to be fixed, and a part of any portion may be a solid structure.

The prior art is a well-known fine structure of a solid structure or a front structure of a hollow structure in which a metal pipe made of stainless steel which is proposed in Patent Document 1 is elongated. Further, as described in Patent Document 1, the solid portion of the front end is a structure in which a rod-shaped member in which a synthetic resin is wound, such as a steel wire or a carbon fiber, is inserted.

In general, although the front end of the solid structure is high in rigidity, if it is compared with the hollow structure, there is weight and sensitivity. not tall. On the other hand, although the front fine structure of the hollow structure is not high in rigidity compared with the solid structure, it has high rigidity as compared with the front fine layer made of fiber-reinforced resin. Further, the front end of the hollow structure is compared with the solid structure, and if it has the same diameter, weight reduction can be achieved, and the diameter of the mast can be relatively freely set in accordance with the design specifications.

However, in the configuration in which the rod-shaped member is inserted as a solid portion in the hollow portion of the front end, which is proposed by the prior art, although the rigidity is adjusted, the weight can be reduced in weight compared with the hollow portion. Further, since the rod-shaped members of different bodies are inserted into the elongated hollow portion of the front end, even if an adhesive or the like is used, it is not easy to be adhered to eliminate the gap. Further, even when the gap is filled, when the center of gravity is deviated from the center of the diameter of the mast due to the deviation between the rod member and the adhesive, the load is twisted and the curved shape is changed when the load is applied.

Therefore, according to the present embodiment, the tip end portion 2a of the head portion 2 is a solid structure 6a having an arbitrary length at the tip end, and the tip end is a hollow structure 6b, whereby the diameter is reduced and the diameter is ensured. The strength of the distal end portion can be reduced by the hollow structure of the tip end holding portion 2b side while maintaining the high sensitivity peculiar to the metal material.

Further, in the modification, even if the tip portion 2a is formed in a hollow structure, the configuration of the hollow tip structure holding portion 2b can be obtained, and the same function and effect can be obtained. Therefore, since the insertion is not performed after the formation of the front fineness to embed the filler in the hollow portion, the center of gravity does not deviate from the center of the diameter of the mast, and the distortion like the deformation of the flaw does not occur.

In addition, although the fishing rod of the embodiment is not equipped with a fishing line guide The fishing rod of the fishing line guide is described as an example. However, even if a fishing line guide is provided, the same function can be obtained.

Next, the second embodiment will be described.

Fig. 3 (a) is a cross-sectional view showing a structure of a front end fine, and Fig. 3 (b) is a cross-sectional view showing a material of a front fine film before processing according to the second embodiment. In the present embodiment, a solid portion in which a plurality of portions are disposed in a hollow portion of the front fine portion is configured.

As shown in Fig. 3(a), in the present embodiment, as in the above, the solid portion 11a of the front end fine 11 is placed on the boring head, and then the hollow portion 11b is disposed. It is a structure in which the solid portion 11c is formed in the middle of the hollow portion 11b. In this configuration, as shown in FIG. 3(b), the tip material 12 having the structure in which the wall portion 12c is added is used in the above-described cover shape (the bottom portion 12a and the cylindrical portion 12b), and the taper is processed by swaging. Make it stretch.

The arrangement or thickness of the wall portion 12c in the tip material 12 can be arbitrarily set, and is set as a result of performing actual machining so as to be a desired position or thickness after the swaging process.

Further, as shown in FIG. 3(c), the narrow portion 13 having a thick thickness may be formed so as to protrude from the inner side in place of the solid portion 11c in the front fine string 11. By arranging the narrow portion 13, the bending shape or the bending condition can be changed by partially changing the bending rigidity. The bending rigidity can be adjusted by adjusting the protruding shape of the narrowed portion 13 or the width thereof.

According to the first embodiment of the present embodiment, high sensitivity and weight reduction in the first embodiment can be achieved, and one or more solid portions or narrow portions 13 can be arranged at an arbitrary position and size in the hollow portion. The stiffness changes locally, in addition to the required bending stiffness or torsional stiffness, to achieve the desired flexural shape. In particular, the multi-section and slender front squeegee can obtain the desired flexural shape, and the movement of the stern tip when the fish bite the hook is changed, and the change can be grasped as sensitivity. Further, although not shown, the thickness may be changed by partially changing the outer tapered portion in the longitudinal direction, and the rigidity may be partially changed.

Next, a third embodiment will be described.

Fig. 4 is a view showing an external configuration of a front end with an introducer according to a third embodiment. Fig. 5 is a view showing a cross-sectional structure of a joint structure of a tip end portion and a tip end holding portion in the front fine boring of the embodiment. In the present embodiment, the same components as those in the above-described first embodiment are denoted by the same reference numerals, and their description is omitted.

In the present embodiment, the tip end portion 2a and the tip end holding portion 2b are connected to each other in the front head portion 21 in which the top guide 23 and the plurality of line guides 24a to 24e are disposed. In the present embodiment, the faucet joint using the joint member 25 will be described as an example. However, it is of course possible to adopt a joint structure of the inserts in which the tip end portion 2a and the tip end holding portion 2b are fitted to each other.

As shown in FIG. 5, the tip end portion 2a and the tip end holding portion 2b constitute a spigot joint structure composed of the joint member 25 forming the joint portion. The joint member 25 is formed into a cylindrical shape of a solid structure by, for example, a metal member or a resin member (a member that is cured by winding the prepreg), and is inserted into both the tip holding portion 2b and the tip portion 2a by the adhesive. And so on. A fishing line is placed between the tip holding portion 2b and the tip portion 2a. The foot part of the introducer is fixed in a state of crossing the gap 27. The gap 27 is buried with an epoxy resin or the like together with the fixed leg of the fishline guide.

According to the present embodiment, it is possible to maintain the strength by the engagement of the joint member 25 and to achieve the same bending state as the deflection state of the front end fine. Further, it is possible to select the hardness of the material of the joint member 25 (such as a fiber-reinforced resin or a metal material), and to adjust the deflection of the front fine. Further, in the present embodiment, the fishing rod in which the fishing line guide is disposed has been described as an example. However, it is of course also applicable to a fishing rod in which the guide is not disposed.

Next, a modification of the third embodiment will be described.

Fig. 6 is a view showing a cross-sectional structure of a joint portion of a front end fine cymbal in an introducer-equipped fishing rod according to a modification of the third embodiment. In this modification, the joint member connecting the tip end portion 2a and the tip end holding portion 2b is changed from a solid structure to a hollow structure.

As shown in Fig. 6, the tip end portion 2a and the tip end holding portion 2b are connected by a joint member 26 having a hollow cylindrical (tube) shape inside.

According to the present modification, the same operational effects as those of the third embodiment described above can be achieved. Further, by adjusting the thickness of the joint member 26, the deflection of the front fineness can be adjusted more than in the third embodiment. For example, the thickness of the joint member 26 may be made thinner than the thickness of the joint member, and the head side may be made thinner than the tail side, so that the amount of deflection on the side of the tip end can be increased. That is, the deflection of the tip end portion 2a and the tip end holding portion 2b can be flexed with a smooth curvature before and after the joint portion.

Next, a fourth embodiment will be described.

Fig. 7 is a view showing a cross-sectional structure of a joint portion of a front end fine cymbal in an introducer-equipped fishing rod according to a fourth embodiment. Fig. 8 is a view showing a cross-sectional structure showing an enlarged portion B of Fig. 7; Fig. 9 is a view showing a cross-sectional structure showing an enlarged portion C of Fig. 7;

The above-described tip portion 2a and the tip holding portion 2b are joined by a joint portion made of a fiber-reinforced resin wound around the end portion of the tip portion. In the present embodiment, the joint member 33 is formed at a level difference at the rear end of the tip end portion, and the tip portion of the joint member 33 is joined to the tip end holding portion 34. In the present embodiment, as in the first embodiment described above, the tip portion 32 is formed of a metal material, and the joint member 33 is formed of the above-described metal material or fiber-reinforced resin.

As shown in Fig. 8, the outer peripheral side of the metal tip portion 32 is polished to form a joint portion 32a which is stepped thin. The joint member 33 is fitted to the joint portion 32a so that the surface portion is a smooth surface (flat surface). Further, it may be fixed by an adhesive or the like (first overlapping structure). Next, as shown in FIG. 9, the joint member 33 is also ground by the outer peripheral side to form a joint portion 33a which is stepped thin. At this time, a laminated structure in which the joint portion 33a and the joint portion 32a overlap each other is formed.

In addition, the joint portion 33a of the joint member 33 is fitted with the tip end holding portion 34 so as to be connected to a flat surface (flat surface), and is fixed by an adhesive or the like (second overlap structure). Therefore, by overlapping the respective joint portions with the tip end holding portion 34, the tip portion 32 is laminated on the tip holding portion 34 with the joint member 33 interposed therebetween.

In the present embodiment, the joint portion 32a and the joint member 33 are connected to the joint surface of the joint portion 33a and the tip end holding portion 34 as a flat surface. This is because the foot portion of the line guide is hung on the seam, and conversely, when the foot portion is not hung, it is not necessary to form it as a flat surface.

According to the embodiment described above, the thickness and the joint area of each joint portion can be adjusted, and the thickness and the amount of overlap (area or length) of the tip end portion 32, the joint member 33, and the tip end holding portion 34 can be adjusted to adjust the front fine The deflection of the cockroach. In particular, in a state in which the joint member 33 is interposed, since the tip portion 32 to the tip holding portion 34 are integrally overlapped, the deflection can be flexed with smooth curvature at each joint portion.

In each of the above-described embodiments and modifications, the hollow structure is applied to the front end to reduce the weight of the fishing rod, and the configuration of the same diameter of the solid structure can increase the rigidity difference between the tip end portion and the tip end holding portion. The deflection caused by the hook on the fish bite hook is easy to change. Therefore, the movement when the tip is deflected together with the feeling transmitted to the hand changes, and the change can be grasped as sensitivity and can be realized. It is easy to grasp and has a good sensitivity. Moreover, sufficient rigidity can be ensured by the hollow structure and partially configured with the solid structural portion, and at the same time, the desired flexural shape can be obtained, not only the flexural state in which the appearance is easily known but also the fish of the hook can be realized. Easy and highly elastic fishing rod.

Moreover, the taper angles of the tip end portion 32 and the tip end holding portion 34 can be varied, that is, each can form a taper of a desired diameter. Accordingly, the portion of the taro is easily deflected, and the hook of the fish bite can be changed. Further, not only the outer shape but also the thickness of the tip portion 32 can be adjusted to set the required rigidity and deflection.
