Description

  The present invention relates to a fishing rod provided with a tip rod made of metal.

  In recent years, fishing rods are made of fiber reinforced resin including reinforcing fibers, and have improved bending rigidity, torsional rigidity, etc., and the diameter and weight of fishing rods have been reduced, making handling easier. As the overall diameter of the fishing rod is reduced, the tip of the fishing rod becomes thinner. However, depending on the type of fish, a large load is applied to the tip of the fishing rod, making it difficult to balance the strength of the fishing rod. In addition, when the tip of the hook is wound up with a reel, the top guide part or the tip of the tip breaks when a local load is applied by winding up the fishing line with a reel. To do.

  Thus, as a means for improving the strength of the tip rod, for example, as proposed in Patent Document 1, a fishing rod using a tapered metal pipe having a uniform taper shape has been proposed. This proposal further describes a technique for performing surface treatment by winding a corrosion-resistant coating or prepreg around the surface of a metal tube. Of course, solid fishing rods are also distributed in fishing rods made of metal materials.

JP-A-53-134686

  In the cited document 1 described above, the metal tube is tapered and tapered using swaging. In addition, it is described that when this method is used, the tip portion becomes thick, so that the thickness is adjusted to be thin by grinding. Moreover, the structure which manufactures a metal plate by roll winding processing or pipe processing is also proposed.

  However, even if it is made flexible by adjusting the wall thickness, it has a uniform hollow structure. However, when a fishing rod having a different thickness is required, simply adjusting the thickness is not versatile and does not provide a satisfactory structure even when applied easily. Also, if it is a long-pointed rod like a kite, it is not possible to make everything with a metal tube, and it is necessary to connect to a resin rod in the middle when looking from the bending state of the whole fishing rod, Document 1 does not provide any technique.

  Therefore, an object of the present invention is to provide a fishing rod having a tip which is light and has sufficient rigidity, bends with good sensitivity in response to fish faith, and has a tip that is easy to distinguish.

  In order to achieve the above object, a fishing rod according to an embodiment of the present invention includes a solid portion having an arbitrary length disposed on a tip side and formed of a metal material extending in a cylinder with a straight axis and the solid portion. Formed by any one of the metal material or the fiber reinforced resin material, the tip part including the hollow part that follows the hollow part, the elongated cylindrical shape formed by the fiber reinforced resin material, and the ear part. And a spear that is composed of a joint part that joins the parts.

  In another embodiment, the tip part including a hollow part having an arbitrary length disposed on the tip side is formed of a metal material extending in a cylinder with a straight axis, and an elongated cylinder formed of a fiber reinforced resin material. It has a scissors that are formed of either a metal holding part or a fiber reinforced resin material, and a joint part that joins the head part and the head holding part.

  According to the present invention, it is possible to provide a fishing rod having a tip that is light and has sufficient rigidity, bends with good sensitivity in response to fish faith, and has a tip that is easy to distinguish.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 (a) is a diagram showing an overall external configuration of a fishing rod according to the first embodiment, FIG. 1 (b) is a cross-sectional view of the material of the tip rod before processing, and FIG. 1 (c) is It is a figure which shows the cross-sectional structure of a tip heel part. As another example, FIG. 2A is a cross-sectional view of a material of a spikelet before processing, and FIG. 2B is a diagram illustrating a cross-sectional structure of a spikelet portion. Hereinafter, as a fishing rod of the present embodiment, a joint rod that is divided into a plurality of pieces and joined by a splicing type, a swinging type, or the like is described as an example. The present invention can be equally applied to a so-called one-piece bag provided with a tip portion.

  As shown to Fig.1 (a), the fishing rod 1 comprises the tip rod 2, the 2nd rod 3, and the main rod 4 from the rod tip side, and comprises one fishing rod. The tip 2 of the present embodiment is made of a resin using a tip 2a employing a metal tip, a resin sheet bonded to the tip 2a, and impregnating a fiber reinforced resin into a reinforcing fiber such as carbon, a so-called prepreg. It is comprised by the head holding part 2b.

  As shown in FIG.1 (c), the tip part 2a of the metal top is formed of a solid part (solid by metal) 6a on the tip side and a hollow part (so-called tubular) 6b. As shown in FIG. 1B, the tip portion 2a of the present embodiment is subjected to a swaging process by using, for example, an elongated cap shape (bottom portion 5a and cylindrical portion 5b) made of a titanium alloy material. It is extended by tapering taper. In addition, in FIG.1 (b), although the cap-shaped tip material is shown, as shown to Fig.2 (a), the pipe-shaped tip material 7 is taper-tapered using a swaging process. As shown in FIG. 2 (b), it may be extended into a pipe shape.

  Moreover, even if the cylindrical tip material 7 is used, depending on the taper taper process, the pipe shape of the thin tip portion can be crushed and can be formed to be a solid part. Moreover, it is also possible to make a part of arbitrary places into a solid structure by inserting and adhering a filling member partially within the hollow tip.

  As a conventional technique, a solid tip (solid structure) or a hollow tip made by extending a metal tube made of stainless steel as proposed in Citation 1 is known. Furthermore, as described in the cited document 1, the solid part of the spikelet has a structure in which a rod-like member in which a synthetic resin is wound around a steel wire or carbon fiber is inserted.

  In general, a solid tip structure having a solid structure can obtain high rigidity, but has a weight and is not high in sensitivity as compared with a hollow structure. On the other hand, the hollow tip of the hollow structure is not high in rigidity compared to the solid structure, but has high rigidity compared to the tip of the fiber-reinforced resin. Furthermore, if the hollow structure of the tip rivet has the same diameter as that of the solid structure, the weight can be reduced, and the diameter of the ridge can be set relatively freely according to the design specifications.

  However, the solid structure by inserting a rod-like member into the entire hollow portion of the tip of the tip proposed in the prior art can adjust the rigidity, but the weight is reduced compared to the hollow portion. I can't. In addition, since a separate rod-shaped member is inserted into the elongated hollow portion of the tip of the tip, it is not easy to close the gap by using an adhesive or the like. In addition, even if the gap is filled, if the bar-shaped member and the adhesive are biased and the center of gravity deviates from the center of the diameter of the heel, twisting occurs when a load is applied, and the curved shape changes. Resulting in.

  Therefore, according to the present embodiment, the tip 2a of the tip of the tip 2 is reduced in diameter by making the tip a solid structure 6a having an arbitrary length and a hollow structure 6b following the tip. By ensuring the strength of the tip portion while realizing the above and making the ear holding part 2b side have a hollow structure, it is possible to maintain the high sensitivity peculiar to the metal material while reducing the weight.

Moreover, as a modification, even if it is the structure which forms the ear | tip part 2a as a hollow structure and succeeds the hollow holding | maintenance part 2b of a hollow structure, an equivalent effect can be acquired. Therefore, since the filling is not inserted so as to embed the filling in all the hollow portions after the formation of the tip ridge, the center of gravity does not deviate from the center of the diameter of the heel, and the twist that inhibits the bending of the heel does not occur.
In addition, although the fishing rod of this embodiment has described the fishing rod in which the fishing line guide is not provided as an example, of course, even if a fishing line guide is provided, an equivalent effect can be obtained.

Next, a second embodiment will be described.
Fig.3 (a) is sectional drawing of the material of the tip spikelet before a process which concerns on 2nd Embodiment, FIG.3 (b) is a figure which shows the cross-section of a tip spikelet. In this embodiment, it is the structure which has arrange | positioned the several partial solid part in the hollow part of the tip.

  As shown in FIG. 3 (a), in the present embodiment, the solid portion 11a of the tip ridge 11 is disposed at the heel, and the hollow portion 11b is subsequently disposed, as described above. Further, a solid part 11c is formed in the middle of the hollow part 11b. As shown in FIG. 3B, this structure is tapered by swaging using a tip material 12 having a structure in which a wall portion 12c is added to the cap shape (bottom portion 12a and cylindrical portion 12b) described above. It is extended by taper processing.

The arrangement and thickness of the wall portion 12c in the tip material 12 can be arbitrarily set, and can be set from the result of actual processing so as to be the position and thickness requested after the swaging processing. preferable.
Furthermore, as shown in FIG.3 (c), the solid part 11c in the tip hook 11 may be the constriction part 13 formed thickly so that it may protrude inside. By providing the narrowed portion 13, the bending shape and the degree of bending can be changed by partially changing the bending rigidity. The bending rigidity can be adjusted by adjusting the protruding shape and the width of the narrowed portion 13.

  According to the tip of the present embodiment, the high sensitivity and light weight in the first embodiment are realized, and one or more solid portions or constricted portions 13 are formed at an arbitrary position and size in the hollow portion. By arranging, the rigidity can be locally changed, and a desired bending shape can be realized in addition to the desired bending rigidity and torsional rigidity. In particular, it is possible to obtain a desired bending shape for a long and narrow tip of the tether, and when the fish is received, a change occurs in the movement of the tip of the tip, and the change can be regarded as sensitivity. Although not shown, the thickness may be changed and the rigidity may be partially changed by partially changing the outer tapered shape in the length direction.

Next, a third embodiment will be described.
FIG. 4 is a diagram illustrating an external configuration of a guide-tip scissor according to the third embodiment. FIG. 5 is a diagram showing a cross-sectional structure showing a joint structure between a tip part and a head holding part in the tip tip of the present embodiment. In the present embodiment, the same components as those of the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, the tip portion 2a and the head portion 2b are connected to each other in the tip rod 21 in which the top guide 23 and the plurality of fishing line guides 24a to 24e are arranged. In the present embodiment, the spigot joint using the joint member 25 will be described as an example. Of course, a joint structure in which the head part 2a and the head holding part 2b are fitted to each other may be employed.

  As shown in FIG. 5, the tip part 2 a and the head holding part 2 b are configured in an inlay joint structure with a joint member 25 that forms a joint part. The joint member 25 is formed, for example, by a metal member or a resin member (a member obtained by winding and solidifying a prepreg, etc.) into a solid cylindrical shape, and the head holding portion 2b and the tip portion 2a are fitted to each other, It is fixed with an adhesive. The foot portion of the fishing line guide is spanned between the head holding portion 2b and the tip portion 2a, and is fixed in a state of straddling the gap 27. The gap 27 is embedded with an epoxy resin or the like together with the foot portion of the fishing line guide fixed to the winding line.

  According to this embodiment, by the spigot joint using the joint member 25, it is possible to realize a bending condition in which the strength is maintained and the bending state of the tip of the tip is uniform. Further, by selecting the material of the joint member 25 in consideration of the hardness or the like of the material (fiber reinforced resin or metal material), it is possible to adjust the degree of deflection of the tip. In the present embodiment, a fishing rod provided with a fishing line guide has been described as an example, but of course, the same can be applied to a fishing rod not provided with a guide.

Next, a modification of the third embodiment will be described.
FIG. 6 is a diagram showing a cross-sectional structure of a joint portion of a tip rod in a fishing rod with guide according to a modification of the third embodiment. In this modified example, the joint member that connects the tip portion 2a and the head holding portion 2b is changed from a solid structure to a hollow structure.
As shown in FIG. 6, the tip part 2a and the head holding part 2b are connected by a joint member 26 having a hollow cylindrical (pipe) shape.

  According to this modification, the same operational effects as those of the third embodiment described above can be achieved. Furthermore, by adjusting the thickness of the joint member 26, it is possible to adjust the degree of deflection of the tip heel more than in the third embodiment. For example, the thickness of the joint member 26 is not constant, but the tip side can be adjusted to be greater than the tip side so that the amount of deflection on the tip side is increased. That is, the bending state of the tip part 2a and the head holding part 2b can be bent with a smooth curvature before and after the joint part.

Next, a fourth embodiment will be described.
FIG. 7 is a view showing a cross-sectional structure of the joint portion of the tip rod in the fishing rod with guide according to the fourth embodiment. FIG. 8 is a diagram showing a cross-sectional structure in which the portion B in FIG. 6 is enlarged. FIG. 9 is a diagram showing a cross-sectional structure showing an enlarged C portion of FIG.

  The above-mentioned head part 2a and the head holding part 2b have a shape joined by a joint part made of a fiber reinforced resin wound around the end part of the head part. In the present embodiment, the joint member 33 is formed at the step at the rear end of the tip portion, and the ear holder 34 is joined to the step formed at the joint member 33. In the present embodiment, similarly to the first embodiment described above, the tip portion 32 is formed of a metal material and is formed of a fiber reinforced resin such as a prepreg, and the joint member 33 is formed of the above metal material or the fiber reinforced resin. It is formed.

  As shown in FIG. 8, the joining part 32a which was ground from the outer peripheral side of the metal tip part 32, and was made thin in steps is formed. The joint member 33 is fitted so that the surface portion is connected to the joint portion 32a as a smooth surface (flat surface). Further, it may be fixed with an adhesive or the like (first overlapping structure). Next, as shown in FIG. 9, the joint portion 33 a that is ground from the outer peripheral side and thinned in steps is also formed in the joint member 33. At this time, the joint portion 33a has a laminated structure in which the joint portion 32a is overlapped.

  Further, the ear support 34 is fitted so that the surface portion is connected to the joint 33a of the joint member 33 as a smooth surface (flat surface), and is fixed with an adhesive or the like (second overlapping structure). Therefore, each joint part is overlapped with the head holding part 34, so that the head part 32 is stacked on the head holding part 34 with the joint member 33 interposed therebetween.

  In addition, in this embodiment, it is set as the structure connected so that the joint surface of the surface side in the junction part 32a and the joint member 33, and the junction part 33a and the earring part 34 may become a flat surface. This is because the foot portion of the fishing line guide hits the joint, and on the contrary, when the foot portion does not hook, it does not necessarily have to be formed as a flat surface.

  According to the present embodiment described above, the thickness and the overlapping amount (area or length) of the tip part 32, the joint member 33 and the ear holding part 34 are adjusted by adjusting the thickness and the joining area of each joining part. By adjusting, it is possible to adjust the deflection of the tip. In particular, since the joint member 33 is interposed so as to have an integral overlap from the head part 32 to the head holding part 34, the bending condition can be bent at a smooth curvature at each joint part. Is possible.

  In each of the embodiments and the modifications described above, the tip of the tip is lightened by applying a hollow structure, and the rigidity of the tip and the tip of the tip is compared with the solid structure having the same diameter. Because the difference can be increased and the deflection due to the hitting of the tip of the tip is easy to change, the movement of the tip of the tip is changed along with the touch transmitted to the hand, and the change can be regarded as sensitivity. An easy-to-take and sensitive fishing rod can be realized. In addition, by arranging the solid structure part in a hollow structure partly, it is possible to obtain the desired bending shape while ensuring sufficient rigidity, and not only the bending state that is easy to see visually, but also the hooked fish A waisted fishing rod that can be easily taken in can be realized.

  Further, the taper angle of the head part 32 and the head holding part 34 can be changed, that is, each can be formed into a tapered shape having a desired diameter. Thereby, it is easy to bend the tip part, and change can be given to the hit by fish faith. Further, by adjusting not only the outer shape but also the thickness of the tip portion 32, the desired rigidity and bending condition can be set.
