Description

  The present invention relates to a fishing rod formed by connecting a plurality of rods, and particularly to a rod located closest to the tip.

  Some fishing rods used for fishing are used by connecting a plurality of rods as a single fishing rod. Many of the rods constituting such a fishing rod are hollow cylindrical members made of fiber reinforced resin. However, in the conventional fishing rod, there is a fishing rod in which the small diameter rod (pointer rod) located closest to the tip of the rod is a solid rod (solid rod). In such fishing rods, this solid rod is bonded and fixed to the second rod connected to the rod side, and the solid rod and the hollow rod constitute the tip rod There is also a thing.

  This structure is adopted because the tip end of the tip of the tip of the tip of the tip is made as small as possible so that it reacts sensitively to the fish and is rich in elasticity. For this purpose, the material is hollow. Specifically, this type of fishing rod has a fitting male portion formed at the base end portion of the solid rod, and the tip end of the second rod body is coated with an adhesive. It is inserted and fixed to the part (see, for example, Patent Document 1).

  In such a spike, it is necessary to sufficiently maintain the connection strength of both the solid and hollow ridges. Various techniques for this have been proposed. For example, in Patent Document 1 described above, irregularities are formed on the surface of the solid connecting portion, and both are bonded and fixed. Moreover, the technique which provides a reinforcement layer in the outer peripheral surface of both connection part is also proposed (refer patent document 2).

However, the problem that occurs in the connecting portion between the solid rod and the hollow rod that occurs in this type of fishing rod is not limited to the maintenance of the coupling force between the two rods as described above. Since the bending rigidity differs between the solid rod and the hollow rod, the bending in the axial length direction in the vicinity of the connecting portion between the both rods becomes not smooth. The head rod is a rod body located on the most tip side that must transmit the force from the fish applied through the fishing line to the entire fishing rod, and the need to make the bend smooth is different from other rods. Big compared to the body.

  The present invention provides a spikelet with a smooth bend in the axial direction.

  A point rod according to the present invention is a point rod located on the most tip side of a fishing rod, and has a main body and a solid rod body having a connecting portion at a heel side end of the main body portion, and a connection between the solid rod body A hollow housing having a receiving portion into which the portion is inserted at the tip side end portion and a connecting portion being inserted and fixed to the receiving portion. The main body portion of the solid rod body has a tapered portion that increases in diameter from the tip side end portion toward the heel side and a non-tapered portion that continues to the heel side of the tapered portion and does not change in diameter in the axial direction. The axial length of the non-tapered portion is 1 to 10% of the axial length of the entire main body.

  In this spike, a part of the main body part adjacent to the connecting part on the base side of the solid rod body is a non-tapered part, and the non-tapered part is set to a predetermined length of the whole main body part. Has been. By setting such a non-tapered portion, an abrupt change in bending rigidity in the axial length direction between the hollow housing and the solid housing is suppressed. When the fish is involved in the mechanism and a large force is applied from the fishing line to the tip of the tip, the bend in the axial length direction of the tip of the tip becomes smooth and the operability is improved.

  Furthermore, you may make it further provide the slide-type guide which is positioned in the predetermined | prescribed axial direction direction position of the surrounding surface of the solid rod body of a tip tip, and can slide to the tip side from a position.

  The solid frame has a pre-made top guide attached to the end of the tip side, and a hollow frame is connected to the base side. The diameter tends to be restricted to a constant diameter. By setting a non-tapered portion on the base side of the solid rod body, in the solid rod body having a certain axial length length, the taper portion taper on the tip side becomes a relatively steep taper. . Since the slide type guide is positioned by being externally fitted at a predetermined position in the axial length direction of the solid casing by the diameter of the inner diameter and the outer diameter of the solid casing, the sharpness of such a taper can be prevented. The slide guide is highly accurate (fixed stability).

  Moreover, in the tip collar according to the present invention, the taper portion of the main body portion of the solid rod body is continuous with the first taper portion extending from the tip end portion toward the collar side and the collar side of the first taper portion. Compared with the taper of the first taper portion, it is divided into a second taper portion having a gentler taper ratio and a diameter increasing toward the base side, and the length of the first taper portion and the second taper portion in the axial length direction is divided. The ratio may be set to be 1: 4 to 1: 5. In this way, in particular, by setting a partially steep taper region on the tip side of the tip of the tip, the tip side particularly shows a sharp reactivity among the tip of the tip, and reacts sensitively to the fish clams.

  The tip of the present invention has a smooth bend in the axial length direction including the solid part and the hollow part, and is excellent in operability.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
A fishing rod that employs the first embodiment of the present invention is configured by, for example, a plurality of rods such as a marine rod, a former rod, and a middle rod being sequentially connected in a parallel manner or the like. A reel sheet 2 for detachably mounting the reel R is provided on the peripheral surface of the main rod 1 which is a casing located closest to the flange side. On the other hand, the most prominent body arranged on the tip side is the ear tip 3, and the ear case 4 is arranged on the base side of the tip end 3. In FIG. 1, the casings located between those other than the former basket 1, the head basket 3 and the head holder 4 are omitted. The main casing 1 and other intermediate casings are cylindrical members made of carbon fiber reinforced resin, glass fiber reinforced resin, or the like, which are tapered to have a diameter that decreases toward the tip side. A fitting portion for connecting the skeletons is formed on the tip side or the heel side of each skeleton. Further, if necessary, a fishing line guide for guiding the fishing line L from the reel R is attached to the peripheral surface of each casing.

  As shown in FIG. 2, the tip rod 3 is formed by connecting a solid rod body 10 on the tip side and a hollow rod body 11 on the hook side and bonding and fixing them to form a single rod body. In the tip rod 3, a top guide 12 is attached to the tip side end portion (that is, the tip side end portion of the solid rod body 10), and the tip side end portion (that is, the collar of the hollow rod body 11). A connecting portion for connecting to the hot pot 4 is formed at the former end portion. Furthermore, a plurality of fishing line guides 13 are also mounted at intervals in the axial direction.

  The solid rod body 10 is a rod-like / solid solid body with a taper that decreases in diameter toward the tip side as a whole. For example, it is formed by pressurizing and heating a carbon fiber reinforced resin in which carbon fibers are aligned in the axial direction and impregnated with a thermosetting resin. Thereafter, the peripheral surface is polished to adjust the outer diameter for each portion as follows.

FIG. 2 schematically shows how the diameter of the solid casing 10 changes.
The solid casing 10 has a main body 10a and a connecting portion 10b formed at the base end of the main body 10a and having a smaller diameter than the main body 10a. The connecting portion 10b has a two-stage structure of a portion that rapidly decreases in diameter toward the heel side and a portion that is continuously formed on the heel side and does not change in diameter in the axial direction. This connecting portion 10b is a portion that is inserted into the end of the hollow casing 11 and connected and fixed with an adhesive or the like. The main body 10a of the solid casing 10 is divided into three regions as follows. That is, the three regions include a first taper portion X that increases in diameter from the tip side end portion toward the heel side, a second taper portion Y that continues to the heel side of the first taper portion X, and a second This is a non-tapered portion Z whose diameter does not change in the axial length direction continuous to the base side of the tapered portion Y. For example, an example of a specific diameter and length of the solid casing 10 is shown. In one example, the entire length of the main body 10a in the axial direction is 500 mm. The outer diameter of the tip side end is 0.75 mm. The outer diameter of the first taper portion X, the second taper portion Y, and the critical point is about 1.10 mm. The axial length of the first taper portion X is 90 mm. The axial length of the second taper portion Y is 400 mm. Here, at the critical point between the second tapered portion Y and the non-tapered portion Z, the outer diameter is set to 1.75 mm. The length in the axial direction of the non-tapered portion Z is 10 mm. In addition, the said numerical value is an example and the length and diameter of each part are not limited to the said numerical value. The length of the non-tapered portion Z in the axial length direction may be set to 1 to 10% of the overall length of the main body portion 1a. The length ratio of the first taper portion X and the second taper portion Y in the axial length direction is preferably 1: 4 to 1: 5.

  The hollow casing 11 is a hollow pipe-shaped member that is tapered so that the diameter is reduced toward the tip side. Like other casings, it is formed from a prepreg material obtained by impregnating a reinforcing resin such as carbon fiber or glass fiber with a synthetic resin. The inner peripheral surface of the end portion on the tip side is cut according to the shape of the connecting portion 10b of the solid rod body 10 described above to serve as a receiving portion. The connecting portion 10b described above is inserted into the receiving portion, and the two casings are connected and fixed by an adhesive or the like. If necessary, an elastic resin paint may be applied to the peripheral surface across the two casings at the connecting portion, or an auxiliary prepreg material may be wound and further baked to integrate the two casings. .

  In the tip rod 3 composed of the solid rod body 10 and the hollow rod body 11, a plurality of slide guides 13 are arranged at predetermined axial length positions spaced apart in the axial length direction. It is attached. This slide-type guide 13 has a pipe-like portion as a fixed portion, and is positioned at a predetermined axial length position by fitting the inner peripheral surface of the pipe-shaped fixed portion and the outer peripheral surface of the tip 3 It is what is done. Therefore, if the fitting of the pipe-shaped fixing portion is released, each slide type guide 13 can be slid to the tip side. If such a slide-type guide 13 is used, each slide-type guide 13 is slid and moved to the tip side, so that each of the rods including the tip rod 3 is sequentially ejected into the rod-side housing. It is also possible to store it in the box.

  Such a sliding guide 13 includes, for example, one in the first taper portion X and two in the axial direction of the second taper portion 2, and a total of three in the head rod 3. The inner diameter of the fixed portion of each slide type guide 13 is set so as to be fitted to the actual housing 10 (see FIG. 2).

  Among such fishing rods, the tip rod 3 has a non-tapered portion Z in a part of the main body portion 10a adjacent to the connecting portion 10b on the heel side of the solid rod body 10. Further, the non-tapered portion Z is set to a certain predetermined axial length with respect to the axial length of the entire main body 10a. By setting such a non-tapered portion Z, an abrupt change in bending stiffness in the axial length direction of the hollow housing 10 and the solid housing 11 is suppressed. When the fish is engaged in the mechanism and a large force is engaged from the fishing line L to the tip rod 3 via the top guide 12 or each slide type guide 13, the bending in the axial length direction of the tip rod 3 becomes smooth. , Operability is improved.

  In particular, by setting the first taper portion X, which is a partially sharp taper region, on the tip side of the solid rod body 10 of the tip tip 3, the tip side especially in the tip tip 3 has a sharp reactivity. Shows and reacts sensitively to fish attack.

  Furthermore, since the solid rod body 10 has a pre-made top guide 12 attached to the end portion on the tip side, and the hollow rod body 11 is connected to the base side, the end portion on the tip side and the hook portion of the main body portion 10a. The outer diameter of the original side end tends to be restricted to a constant diameter. By setting the non-tapered portion Z on the base side of the solid rod body 10, in the solid rod body 10 having a certain axial length direction length, the first taper portion X and the second taper on the tip side thereof. The taper of the portion Y becomes a relatively steep taper. The sliding guide 13 is positioned by being externally fitted at a predetermined position in the axial length direction of the solid casing 10 by the diameter of the inner diameter of the fixed portion and the outer diameter of the solid casing 10. A sudden taper improves the fixing accuracy of the sliding guide 13 (stability when fixed).
