Description

  The present invention relates to a fishing rod, and in particular, to a fishing rod having a characteristic of a pointed rod.

Conventionally, as disclosed in Patent Document 1, for example, a solid-shaped tip rod is inserted into a tubular head rod, and both are fixed by bonding, and the tip rod is bent flexibly. This is known. The spike head has a taper portion that decreases in diameter toward the head holding hook and a fitting portion that extends further from the taper portion toward the head holding hook side at the base end portion of the solid tip hook. In addition, the ear end has a taper portion that gradually increases in diameter toward the tip so that the taper portion of the tip end contacts the tip opening edge. For this reason, when a solid-shaped spikelet is inserted into a tubular spike holder, both taper portions come into contact with each other and are joined together.

  By the way, it is desirable that the above-described solid-shaped spike tips and tubular spike holders are connected in a straight line in consideration of balance when they are inserted and fixed integrally with an adhesive.

  However, when forming each of the solid-shaped spikelet and the tubular spikelet, when bending occurs in the axial length direction, or when forming the tapered portion in the region that becomes the joint portion as described above, Processing errors may occur, and if you insert a spike head and a hochi-mochi in a state where such bending or processing error has occurred and apply the taper parts to each other and join them together, they can be connected in a straight line It may not be possible.

  The present invention has been made on the basis of the above-described problem, and when a solid-colored spikelet is inserted into and bonded to a tubular spikelet, a fishing rod that becomes a spikelet joined together in a straight line The purpose is to provide.

  In order to achieve the above-described object, the fishing rod according to the present invention has a tip rod formed by inserting a solid-shaped tip rod into a tubular spike rod, and the front end of the tubular spike rod A cutout portion is formed in the partial region.

  According to the fishing rod having the above-described configuration, when the solid-shaped spikelet is inserted into the tubular spike holder and fixed with an adhesive, the tubular spike holder does not have to be connected in a straight line due to a processing error or the like. Since the notch portion is formed in the opening region, the diameter of the opening portion of the hot pot can be increased. For this reason, it is possible to finely adjust the axial direction of the spikelet and align it so that they are in a straight line. By bonding the two in this state, the spikelet spliced in a straight line A cocoon is obtained.

  According to the present invention, when a solid-shaped tip rod is inserted into a tubular head rod and bonded, a fishing rod is obtained that becomes a tip rod joined together in a straight line.

  1 and 2 are views showing a first embodiment of a fishing rod according to the present invention, FIG. 1 is a diagram showing an overall configuration, and FIGS. 2 (a) to 2 (d) show a configuration of a tip rod. It is a figure and is the figure which showed in order the manufacturing process at the time of creating a spikelet.

  The fishing rod 1 according to the present embodiment includes a base rod 3, a plurality of middle rods 5, and a tip rod 10, and the rods are joined together by a side-by-side type or a swing-out type. In this case, there may be a configuration without the intermediate rib 5, or a large number of pieces may be joined as shown in FIG.

  The base rod 3 and the center rod 5 are tubular bodies made of fiber reinforced resin. For example, a so-called prepreg sheet in which a reinforcing fiber (mainly carbon fiber, glass fiber, etc.) is impregnated with a synthetic resin is wound around a core metal. After passing through the heating step, it is formed in a predetermined size according to a conventional method such as decentering.

  Further, the fishing rod 1 may be of a type to which an outer guide for guiding the fishing line from the reel R is attached, or such an outer guide is not attached, and the fishing line that fastens the fishing line to the tip of the tip rod 10. The structure which attached the fastener may be sufficient.

  The tip cocoon 10 is composed of a solid stylus cocoon 12 on the tip side and a tubular stylus cocoon 15 into which the tip cocoon 12 is inserted.

  The tip cocoon 12 constituting the tip cocoon 10 is made of a solid and columnar material. Specifically, for example, a material such as glass fiber reinforced resin that has low rigidity and is easily bent, or a core material (solid core material) formed of glass fiber reinforced resin is provided with a coating layer made of fiber reinforced resin. If it is configured as a solid as a whole, it is not limited to a specific material.

  In the tip end 12 formed of the above-described material, an insertion portion 13 is formed on the rear end side thereof. The fitting portion 13 has a tapered portion 13A that is reduced in diameter toward the head holding rod and a columnar portion 13B that extends further from the tapered portion toward the head holding rod side.

  In addition, the hochi-mochi 15 that constitutes the tip cocoon 10 is a tubular body made of a fiber reinforced resin, like the above-described middle cocoon and the former cocoon, for example, a reinforced fiber (mainly carbon fiber or glass fiber). A so-called prepreg sheet impregnated with a synthetic resin is wound around a metal core, subjected to a heating step, and then decentered.

  A tapered portion 16 that gradually increases in diameter toward the distal end is formed at the distal end portion of the spike holder 15 so as to be in contact with the tapered portion 13A in a state where the fitted portion 13 of the spike collar 12 is fitted. ing.

  Further, a notch 20 is formed in the front end region of the tip of the hot pot 15 by notching a tubular portion. The notch 20 only needs to be configured so that the opening edge 15A of the head holder 15 can be expanded in the radial direction. By forming such a notch 20, the ear ridge 12 is inserted. At this time, since the fitted portion can be radially expanded, it is possible to finely adjust the central axis of the tip ridge 12 (adjustment operation so that the central axis of the tip ridge 12 coincides with the central axis of the spike holder 15). Become.

  The notch 20 of the present embodiment is configured by slits 21 extending in the axial length direction at predetermined intervals (four locations at approximately 90 ° intervals) along the circumferential direction on the opening edge 15A of the hot pot rod 15. Has been.

  Such a slit 21 can be formed by forming a tubular body and then cutting from the end side. By forming such a slit 21, the opening of the hot pot 15 is formed. As shown by the arrow in the cross-sectional view of FIG. 2A, the edge 15A can be increased in diameter over 360 °. It is possible to adjust and join them in a straight line.

  Specifically, as shown in FIG. 2 (b), the adhesive 25 is applied to the surface of the insertion portion 13 of the spikelet 12, and the spikelet 12 is inserted in this state. Make fine adjustments so that the central axes match. Then, in a state where the center axes of the two coincide with each other, as shown in FIG. 2C, the fastening tape 27 is wound from the outside to fix them together. After that, the fastening tape 27 is peeled off and a predetermined surface treatment (polishing, coating, etc.) is performed to form the tip hook 10.

  In this state, by the fine adjustment process described above, the tip 12 and the head 15 are aligned and joined in the axial length direction, so that the tip is not bent or twisted as a whole.竿 杆 10 is obtained.

  In addition, since the slit 21 extends in the axial direction, it suppresses the progress of cracks (circumferential cracks) that are likely to occur at the joint between the tip rod 12 and the head rod 15 when the tip rod is bent. It becomes possible to do. In addition, the crack here is a crack in the circumferential direction that occurs in the coating film at the position of the opening edge 15A (when it occurs in the surface layer region) when the tip end 12 is joined to the end holder 15 and the surface is painted. And the main body is not cracked). Such a crack (break) is caused by, for example, the difference in rigidity between the tip 12 and the head 15 when the both edges are curved. Occurs in the part. By forming the slits 21 as described above, it is possible to suppress such circumferential cracks.

  In addition, you may form the reinforcement layer 30 as shown in FIG.2 (d) in the outer layer of the joining part 17 of the head spear 12 and the head holder 15 which are joined as mentioned above. The reinforcing layer 30 can be formed, for example, by winding a fiber reinforced resin sheet (prepreg sheet), heating and firing, or winding the fiber reinforced resin sheet as shown in the drawing.

  Thus, by forming the reinforcing layer 30 on the outer layer of the joint portion 17, it is possible to suppress radial expansion at the notch 20 portion, and from the above-described cracks and opening edges in the axial direction. It becomes possible to prevent the tearing toward. In particular, it is possible to effectively prevent cracks from occurring in the slit portion and tearing along the axial length direction at the base portion of the slit even if the tip rod 10 is greatly bent during actual fishing.

  In the case of a fiber reinforced resin sheet, the reinforcing fibers are aligned in the inclined direction, or in the biaxial or triaxial direction so that the tearing when bent can be effectively prevented and the bending becomes easy. It is preferable to use one.

  FIG. 3 is a diagram showing a second embodiment of the present invention, where (a) is a diagram showing the configuration of a spike candy and a spike holder, and (b) is a joint of the spike candy and the spike holder. It is a figure which shows a state.

  In this embodiment, the slits 41 constituting the notches 20 are formed on the opening edge 15A of the hot pot 15 along the circumferential direction at predetermined intervals (four locations at approximately 90 ° intervals), and each slit. Has a shape in which the opening edge side is wide and the slit width is gradually narrowed toward the base end side. That is, the notch 20 is formed by cutting the opening edge 15A into a mountain shape.

  According to the cutout portion 20 having such a shape, it becomes easier to expand the diameter in the radial direction as compared with the above-described embodiment, so that the range of fine adjustment of the tip ridge 12 can be further expanded. Become. Moreover, since the direction of the slit 41 is also different from the direction of the crack (crack) which becomes the circumferential direction as described above, it is possible to suppress the progress thereof as in the above-described embodiment.

  Furthermore, in the above-described configuration, the adhesive easily enters the slit portion at the time of joining the head rod 12 and the head rod 15, so that it is possible to improve the holding force against the circumferential torque.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the shape of above-described embodiment, It can change variously. For example, the cutout portion formed in the front end region of the above-described hochimochi bowl 15 is formed at a predetermined interval along the circumferential direction, for example, as shown in FIG. 4 in addition to the slits as described above. It is also possible to configure with a hole 50. The shape and the number of such holes 50 are arbitrary (however, they are arranged uniformly so as to expand the diameter over 360 °), and after forming a tubular body, drilling and cutting are performed. It is possible to form.

  In this way, by forming the notch portion with the hole 50, as in the case of the slit described above, the center axis of the tip can be finely adjusted, and the adhesive enters the hole 50. The holding force can be improved with respect to the circumferential torque. In addition, since the adhesion between the tapered portions of the tip 12 and the head 15 is strengthened, it is possible to improve the bonding strength between them. Of course, you may comprise a notch part with the above-mentioned combination of a slit and a hole.
