Description

  The present invention relates to a fishing rod including a tip rod including a hollow tip portion formed 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 fishing line winds up the fishing line with a reel, or when a hook is applied and a local load is applied, the top guide fitting part or the tip part breaks. An accident occurs.

  On the other hand, as a technique for improving the strength of the spikelet, for example, Patent Literature 1 proposes a spikelet using a solid metal rod as a tip part (small diameter rod). The prepreg sheet is attached so that the small-diameter frame has a tapered inclination (taper) from the front side of the connecting portion (the former side end of the small-diameter frame) to be inserted into the end portion (large-diameter frame). An inclined joint portion wound and solidified is provided. The large-diameter housing into which the connecting portion is inserted is formed in a hollow structure in which a prepreg sheet is wound in a tapered shape. The taper of the inclined connecting portion is provided so as to be connected to the taper of the large-diameter frame without a step.

  The cited reference 1 described above is a joint structure in which the tip of the tip is inserted into a large-diameter casing formed of a hollow resin member with a joint portion of a metal solid rod-shaped tip (small-diameter casing). For this reason, the rigidity of the overlapping part of the housing by the rod member and the resin member that become the connecting portion is larger than before and after. In Cited Document 1, since an inclined joint portion is provided on the tip side leading to the joint portion, a smooth hanging curve is obtained from the small-diameter housing to the insertion opening end of the large-diameter housing. However, it has a structure in which stress tends to concentrate at the boundary with the hollow portion of the large-diameter frame following the solid joint. For this reason, the connection from the joint portion to the large-diameter frame is not a continuous continuous curve.

  Therefore, the present invention has a structure having a high rigidity and a smooth hanging curve by connecting a tip portion having a hollow structure at least at a portion related to the joint portion to a hollow portion or a solid-structured head holding portion, and receiving fish trust. An object of the present invention is to provide a fishing rod having a tip that is bent with high sensitivity and is easy to distinguish.

In order to achieve the above object, a fishing rod according to an embodiment of the present invention is provided with a tip having a first joint portion in which a metal tube material is elongated straight from the tip of the tip and is straight at least on the heel side. And a second joint location of a hollow structure or a solid structure , which is formed of a fiber reinforced resin material, has a straight shape at least at the tip side, and fits into the first joint location . comprising the intersubunit portion, when inserted, said the first between the ends of the ear sandwiching member and the end portion of the joint, have at least the metal pipe of clearance distances change due to thermal expansion of the material you, that have a ear Sakisao.

  According to the present invention, at least the portion related to the joint has a hollow structure with a tip part having a hollow structure or a solid structure, and has a high rigidity and a smooth hanging curve. It is possible to provide a fishing rod having a tip that can be easily received and flexed with high sensitivity.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram illustrating a conceptual configuration example of a tip of a fishing rod according to the first embodiment. Hereinafter, the head kite of each embodiment is equally applied to any of the joints that are divided into a plurality of pieces and joined together by a side-by-side type etc. to become a single kite, or a total kite, a so-called one-piece kite, or a swing kite can do. Further, in the following description, at the position where the heel is present, the heel side with a small diameter is referred to as the tip side or the tip side, and the heel end side with a large diameter is referred to as the heel side or the rear end side.

  As shown in FIG. 1, the fishing rod 1 has a configuration example in which a plurality of joints (not shown) are connected to the base after the head rod (first node) 4 and the second rod (second node) 5. It is. The tip 4 is integrally formed by joining the tip 2 formed of a metal material to be the tip and the tip 3 formed of a resin material.

  The tip portion 2 of the present embodiment has a tapered hollow structure (so-called so-called tapering process) in which a metal tube material is tapered by tapering using a swaging process so that the diameter of the tip extends from the tip to a straight axis. , Tubular). The tip 2 is made of, for example, a Ni—Ti alloy, a Ni—Ti—Fe alloy, a Ni—Ti—Cu alloy, a β titanium alloy (β phase: body-centered cubic), or Ni—Ti as a metal material. A synthetic metal having an elastic elongation (elongation) of 3% or more, preferably 5 to 8%, using a material such as a Cr-based alloy is suitable. In this example, the tip portion 2 is formed so that at least the heel side opens with a hollow structure (pipe structure).

  The panicle holding part 3 is formed in a taper shape in which a fiber reinforced resin sheet in which a reinforced fiber such as carbon is impregnated with a resin, a so-called prepreg is wound, and a hollow structure is formed so that the heel diameter increases toward the buttock side. The winding of the sheet differs in rigidity and bending characteristics depending on the winding direction of the fiber of the sheet. The general fiber direction is wound so as to be parallel or orthogonal to the longitudinal direction (straight axis direction) of the fishing rod. Furthermore, by adding two fiber directions with an inclination of ± 45 degrees with respect to the crossing direction, for example, the longitudinal direction (straight axis direction) of the fishing rod, the twisting prevention of the rod and the characteristics of the rigidity and the hanging curve Can be changed. Further, a connecting portion 3 a that is fitted into the opening end of the tip portion 2 is provided at the tip of the tip portion 3 that is joined to the tip portion 2.

  The connecting portion 3a has any one of a hollow cylindrical shape, a hollow frustum shape, a solid columnar shape, and a solid frustum shape. The connecting portion 3a is fitted into the tip portion 2 and fixed using an adhesive or the like. In the following description, the connecting portion or the connecting member suggests a portion that is bonded and fixed together using adhesion or the like, and the joining portion or the joining member suggests a portion that is detachably fitted together.

Although the ear holding part 3 of the present embodiment has a hollow structure made of a fiber reinforced resin material as an example, it may be a solid structure filled with an equivalent or different resin material. Further, similarly to the tip part 2, the head holding part 3 can be formed in a hollow structure or a solid structure by using the same processing method using a metal tube material. When both the tip part 2 and the head holding part 3 are formed of a metal material, a desired bending condition and rigidity can be set by combining not only the same metal material but also metals having different characteristics. For example, if you want a super elastic effect and a flexible bend for the tip part 2, Ni-Ti alloy is used, and a β-titanium alloy is used for the head holding part 3 to reduce weight. For example, various combinations can be implemented.
Also, if the fishing rod is designed to have a fishing line guide, it is arranged so that the foot part of the guide hangs on this joint part, and the wound line or resin material used to fix the foot part is used to reinforce the joint part. It is also possible to do.

In addition, although the tip part 2 of this embodiment demonstrated as an example the hollow structure, if a junction part or a junction location is at least a hollow structure, in a tip side, a filler, for example, a resin member will be melt | dissolved in a hollow structure. Then, the strength may be increased as a solid structure closely embedded.
Furthermore, in order to detachably attach to the succeeding second basket 5, a joint formed in a straight columnar shape (solid) or a cylindrical shape (hollow) on the heel side of the head holding part 3 The part 3b is provided so as to extend. This joint part 3b is detachably fitted into the joint opening end of the subsequent second cage 5.

  As described above, according to the present embodiment, the tip portion of the hollow structure made of the metal material in the tip tip has high rigidity and maintains high sensitivity compared to the tip portion made of the fiber reinforced resin. Yes. Furthermore, if it is the same diameter, weight reduction is realizable compared with the tip part of a solid structure. For the hollow structure, the selection of the metal material and the thickness (the thickness of the salmon) enables the design specifications of the rigidity, the hoop curve (the bent shape of the salmon when the fish is caught) and the diameter of the salmon. It can be designed relatively freely.

  Furthermore, in this embodiment, since it is the structure which fits the connection part of the head holding part 3 inside the opening of a tip part, with respect to the external fitting structure which covers the connection part (hollow structure) of the head holding part 3 on a tip part As a result, the rigidity of the joint can be kept low, and a curve with no sudden curvature change can be realized. Therefore, not only the sensitivity transmitted to the hand, but also the magnitude of the load (the size of the fish caught) can be seen from the angle of the angler.

[Second Embodiment]
Next, a second embodiment will be described. FIG. 2 is a diagram illustrating a configuration example of a joint portion of the tip of a fishing rod according to the second embodiment. This embodiment has a so-called inlay-type joining structure in which the tip part and the head holding part of the tip heel use a straight connecting member.

  The tip portion 11 of the present embodiment is formed in a hollow structure or at least in the vicinity of the joint portion using a metal material equivalent to that in the first embodiment. The tip portion 11 has a tapered shape that tapers on the tip side, and only a hollow joint portion 11 a into which the spigot member 13 is fitted is formed in a straight shape. The panicle holding part 12 is formed in a taper shape in which a fiber reinforced resin sheet obtained by impregnating a resin such as carbon and a so-called prepreg is wound and a hollow structure is formed so that the heel diameter increases toward the buttock side. The Also in the panicle holding part 12, only the joining part 12a of the hollow structure which inserts the spigot member 13 is formed in straight shape.

  The spigot member 13 is made of a resin material equivalent to the head holding portion 12 and has a straight cylindrical shape (hollow pipe: hollow structure) having an outer diameter that is fitted into the inner diameter of each joint portion without a gap, or a columnar shape. (Solid structure). The spigot member 13 is not limited to the resin material, and may be formed in a hollow structure using a metal material equivalent to the tip portion 11. The rigidity can be adjusted by selecting the type of metal and adjusting the thickness.

  Usually, in the tip part 11 in which the spigot member 13 is inserted, the rigidity differs stepwise at the boundary between the overlapping part and the non-overlapping part with the spigot member 13. The boundary of the overlapping part with the spigot member 13 is the same in the head holding part 12 as well. On the other hand, by changing the rigidity of the inlay member 13 by slightly lowering the rigidity of the inlay member 13 by slightly lowering the rigidity of the inlay member 13, the rise or fall of the rigidity step of these boundary portions is inclined. The width can be reduced. That is, the change in rigidity from the head part 11 to the head holding part 12 can be reduced, the step-like change in the curve characteristic can be reduced, and the transmission of sensitivity is further improved.

  The length of the spigot member 13 has a length obtained by combining at least the joint portions 11a and 12a to be inserted. The spigot member 13 shown in FIG. 2 is formed so as to be slightly longer than the combined length, and is formed so that a gap is formed at the time of joining. This gap is not necessarily required, but is used as a joining margin or at least a distance considering thermal expansion in the metal forming the tip portion 11. Note that this gap is used as a filling point of the adhesive when painting the candy. For example, it may be filled with an epoxy resin or the like and processed so as to connect the joint portions 11a and 12a flatly. In addition, the member that fills the gap is preferably a member having elasticity even in a solidified state.

  Furthermore, the spigot member 13 is not only formed of one type of material, but may be a hollow laminated structure including, for example, an outer layer of a metal material and an inner layer of a resin material. On the contrary, a hollow laminated structure with an outer layer of a resin material and an inner layer of a metal material may be used. Further, a cylindrical outer layer made of a metal material and a solid structure in which a resin material is filled in the cylindrical shape may be used.

  According to this embodiment, it can join smoothly, without enlarging the outer diameter of a joining location by interposing a spigot member in the inner side of a tip part and a head holding part. Further, since the joining portion has a straight shape, for example, if a fishing rod to which a fishing line guide is attached, the fishing line guide can be more stably fixed by disposing a guide foot on the straight portion. Further, the guide foot portion is arranged across the gap portion, so that the joint portion between the tip portion and the head holding portion can be more firmly joined.

Is provided. Moreover, you may form the panicle holding part 14 in a hollow structure. In the vicinity of the tip of the panicle holding portion 14, a length similar to that of the joint portion 11a may be formed in a straight shape.

  The length of the connection part 15 has at least the length (inserted length) of the joining location 11a. The connecting portion 15 shown in FIG. 3 is formed to be slightly longer than this length, and is formed so that a gap is formed at the time of joining. This gap is not always necessary, but if provided, it is at least a distance considering the thermal expansion of the metal forming the tip portion 11. Further, similarly to the first embodiment described above, the gap may be filled with, for example, an epoxy resin or the like, and processing may be performed so as to connect the joint portion 11a and the head holding portion 14 flatly. In addition, the member that fills the gap is preferably a member having elasticity even in a solidified state.

  According to the present embodiment, the joint portion provided at the tip of the head holding portion is fitted and joined to the connection portion of the hollow structure of the tip portion, thereby smoothly joining without increasing the outer diameter of the joint portion.
