Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tip rod, and more particularly to a pen tip for a through rod through which a fishing line is inserted.
[0002]
[Prior art]
In the penetrating rod, the fishing line passes through a fishing line provided in the rod body when the fishing line is fed and wound. The fishing line extends outward from the tip of the housing. In such a penetrating rod, when the fishing line passes through the fishing line, the fishing line comes into contact with the inner surface of the fishing line and receives a sliding resistance, and when this sliding resistance is large, the fishing line is fed or wound. It is difficult to remove smoothly. In addition, since the direction of the fishing line changes at the tip of the rod, the fishing line is easily rubbed and cut or weakened at the corner of the rod tip.
[0003]
Therefore, in order to reduce the sliding resistance in the fishing line, a spiral line is formed in the fishing line and the protrusion is used as a fishing line support (Japanese Utility Model Publication No. 5-88259). ). In this technique, the spiral convex portion, which is a fishing line support portion, is formed of the same material as that of the casing, and the convex portion is not easily separated from the casing and has excellent durability. In addition, since the tip surface of the convex portion has a certain area, the contact area with the fishing line is moderate, and it is possible to prevent a problem of contact stress from occurring in the convex portion and the fishing line.
[0004]
In addition, a top guide is provided at the front end of the housing in order to protect the fishing line at the front end of the housing. The top guide has a tapered tubular body made of metal or the like and spreads toward the tip, and a protective ring made of ceramic with a small friction coefficient attached to the inner surface of the tubular body. This tube is fixed to the outer periphery of the tip of the tip of the tip by fitting. In this top guide, the protective ring smoothly guides the fishing line to prevent the fishing line from being cut or weakened.
[0005]
A specific technique of the top guide is disclosed in Japanese Patent Laid-Open No. 4-117232. This technique reduces the resistance when the fishing line passes by forming the radius of curvature of the cross section of the protective ring arranged on the inner surface of the tip of the top guide to be equal to or greater than the radius of the tip of the housing.
[0006]
[Problems to be solved by the invention]
By combining the two conventional techniques, the contact resistance to the fishing line in the fishing line path and the top guide can be reduced, and the fishing line can be protected and the fishing line can be moved smoothly.
However, in the latter technique when combining the conventional techniques, there is a problem in that the inner diameter of the protective ring of the top guide is larger than the inner diameter of the heel body, so that it comes into contact with the convex portion at the tip formed on the inner surface of the heel body. Since the convex portion is formed by winding a tape having a rectangular cross section around a mandrel in the former technique, the convex portion has a rectangular cross section. For this reason, when the two conventional techniques are combined, the fishing line may come into contact with the projection on the tip side, and the fishing line may be worn out or the passage resistance of the fishing line may increase.
[0007]
An object of the present invention is to reduce contact between a fishing line and a fishing line support portion on the tip side of the main body of the rod body in a penetrating rod head with a top guide attached to the tip of the main body having a convex fishing line support portion. An object of the present invention is to reduce the passage resistance of the fishing line and to sufficiently protect the fishing line.
[0008]
[Means for Solving the Problems]
The threading rod for threading rods according to the first aspect is a rod for threading rods through which the fishing line is inserted, and includes a rod body, a fishing line support part, and a top guide. The rod body has a fishing line passage inside. The fishing line support portion is disposed at least at a part on the tip side of the inner surface of the fishing line passage, has a trapezoidal cross section, and has an arcuate portion at an inner peripheral corner. The top guide has a cylindrical guide body disposed on the tip side of the heel body, a semicircular cross section mounted on the inner surface of the guide body, and a circular arc portion having a radius of curvature larger than the radius of curvature of the arcuate portion. One or a plurality of guide rings having an inner diameter on the main body side smaller than the inner diameter of the fishing line support portion.
[0009]
Here, the fishing line is prevented from being damaged by excessive stress because it contacts the inner periphery of the fishing line support portion having a trapezoidal cross section within the rod body. Moreover, since the inner diameter of the guide ring on the rod body side is smaller than the inner diameter of the fishing line support portion, the fishing line is less likely to contact the fishing line support portion on the tip side, and the fishing line is less likely to be damaged on the tip side of the rod body. Even if the fishing line comes into contact, the fishing line support portion has an arc-shaped portion, so that the passage resistance is small and the fishing line is hardly damaged. Further, since the radius of curvature of the arc portion of the guide ring is larger than the radius of curvature of the arc portion of the fishing line support portion, the resistance when the fishing line passes can be reduced.
[0010]
The threading rod for threading according to the invention 2 is easy to manufacture in the rod according to the invention 1 because the fishing line support portion is formed in a spiral shape. Further, since the fishing line support portion can be formed integrally with the rod body, the fishing line support portion is not easily peeled off from the rod body, and the fishing line support portion is not easily damaged.
In the saddle according to claim 1 or 2, the penetrating rod for threading according to the third aspect of the present invention is such that the fishing line support portion has a trapezoidal outer peripheral width of 0.6 to 1.2 mm and a height of 0.1 mm. Since it is 2 to 0.6 mm, the area of the connecting portion between the fishing rod support portion and the main body of the fishing rod is appropriately secured, the strength and durability of the fishing line support portion are improved, and an appropriate interval is provided from the inner surface of the fishing line path. Can support the fishing line well.
[0011]
Here, if the width | variety of an outer side is too narrow, the intensity | strength and durability of a fishing line support part will fall. On the other hand, if the width is too wide, the width of the inner periphery of the trapezoidal cross section increases accordingly, so that the contact resistance with the fishing line increases and the fishing line does not move smoothly. If the height of the trapezoidal cross section is too high, the internal space of the fishing line path becomes narrow and it becomes difficult to pass the fishing line. If the height is too low, when wet fishing line passes, moisture accumulates between the inner surface of the fishing line path between the fishing line support parts and the fishing line, creating resistance to the movement of the fishing line and making it difficult for the fishing line to move smoothly. . In addition, even when the fishing line is not wet, it is easy to come into contact with the inner surface of the fishing line and the resistance against the fishing line increases.
[0012]
In the fishing rod according to any one of the inventions 1 to 3, the guide rod for the through rod according to the invention 4 is a tube portion formed integrally with the rod main body on the tip side and having a thickness thicker than the rod main body. A tip fishing line support part arranged on the inner surface of the cylinder part and continuing to the fishing line support part, a fitting cylinder part fitted to the inner surface of the opening end of the cylinder part, and an inner surface screwed to the inner surface of the fitting cylinder part Has a tapered guide tube portion that expands toward the tip side, and a guide ring is mounted on the inner surface of the guide tube portion.
[0013]
Here, since the guide cylinder part fitted with the guide ring via the fitting cylinder part is screwed to the cylinder part formed integrally with the bag main body, only the part can be replaced even if the guide ring is damaged. .
In the fishing rod according to any one of the inventions 1 to 3, the guide rod for the through rod according to the invention 5 is a taper-shaped resin that is fitted on the tip side outer periphery of the rod body and has an outer surface extending toward the tip side. A cylindrical part and a two-stage step part which is arranged on the inner side of the tip part of the cylinder part and whose tip side has a larger inner diameter than the proximal side, and there are two guide rings attached to each of the step parts. The inner diameter of the guide ring is smaller than the inner diameter of the fishing line support portion, and the inner diameter of the guide ring on the tip side is larger than the inner diameter of the fishing line support portion.
[0014]
Here, since the cylindrical portion is made of resin, the weight of the top guide can be reduced. In addition, since the guide ring is also arranged at the tip of the tube portion, the fishing line is unlikely to contact the tube portion, and the tube portion is not easily damaged even if it is made of resin. Furthermore, since the outer shape is a tapered shape, the fishing line is not easily entangled.
In the fishing rod according to the fifth aspect of the present invention, the point rod side guide ring is mounted from the inner surface of the step portion to the end surface, so that the fishing line is more in contact with the cylindrical portion made of resin. This makes it difficult to damage the tube portion.
[0015]
In the fishing rod according to any one of the inventions 1 to 3, the guide rod for the through rod according to the seventh aspect of the present invention is a tube portion formed integrally with the rod main body on the tip side and having a thickness larger than that of the rod main body. A tip fishing line support portion disposed on the inner surface of the tube portion and continuing to the fishing line support portion; and a step portion formed on the inner surface of the opening end portion of the tube portion, and the guide ring is directly attached to the step portion. Yes.
[0016]
Here, since the guide body is formed integrally with the rod body, the outer diameter of the top guide is not so large as compared with the rod body, and the fishing line is not easily entangled.
In the fishing rod according to any one of the inventions 1 to 7, the guide rod for the through rod according to the invention 8 is made of cermet ceramics, so that the surface is smooth, the friction coefficient is low, and the durability is also high. . For this reason, the resistance of the fishing line can be reduced and the durability of the top guide can be increased.
[0017]

An arcuate portion 45 is provided at an inner peripheral corner portion of the fishing line support portion 40. Arc-shaped portions 46 are also provided at the outer peripheral corners of the fishing line support portion 40.
[0020]
The fishing line support portion 40 has an outer peripheral width W2 set to 0.6 to 1.2 mm. Because of the trapezoidal cross section, the inner peripheral width W1 is slightly smaller than the outer peripheral width W2. The height H is set to 0.2 to 0.6 mm. As described above, the fishing line support portion 40 is formed in a spiral shape, but its lead angle θ (see FIG. 2) is set to 50 ° or less.

[0021]
In order to provide the fishing line support portion 40 having such a structure on the rod main body 14A, the manufacturing technique disclosed in the aforementioned Japanese Utility Model Laid-Open No. 5-88259 can be applied. In this manufacturing process, conditions such as the width, thickness, winding lead angle, etc. of the resin tape wound around the mandrel for manufacturing the bag main body 14A, or the characteristics of the prepreg, the characteristics of the synthetic resin and the reinforcing fiber constituting the prepreg By adjusting the above, the trapezoidal shape structure of the fishing line support portion 40 is formed.
[0022]
The intermediate rod 13 has five layers as shown in an enlarged view in FIG. The basic structure of the marshal 12 is the same as that shown in FIG.
The intermediate rod 13 has a fishing line passage 15b in the inside, like the tip rod 14. The wall surface of the innermost first layer 13a, that is, the wall surface of the fishing line passage 15b is a smooth surface, and no convex fishing line support portion is formed. On the outer periphery of the first layer 13a, a second layer 13b, a third layer 13c, a fourth layer 13d, and a fifth layer 13e are sequentially stacked. Each of the layers 13a to 13e is formed of a prepreg in which a large number of reinforcing fibers are embedded. In the first layer 13a and the fifth layer 13e, the reinforcing fibers are oriented in the circumferential direction, and in the second layer 13b, the third layer 13c, and the fourth layer 13d, the reinforcing fibers 44 are oriented in the axial direction.
[0023]
As shown in FIG. 6, the top guide 18 includes a thick tube portion 51 that is integrally formed at the tip of the rod main body 14 </ b> A of the tip rod 14, and a fitting that is fitted to the inner peripheral surface of the tip of the thick tube portion 51. It has a combined tube portion 52, a guide tube portion 53 that is screwed onto the inner peripheral surface of the tip of the fitting tube portion 52, and a guide ring 54 that is fitted into the inner peripheral surface of the guide tube portion 53.
The thick-walled cylinder portion 51 is formed integrally with the heel body 14A by forming a plurality of layers of prepreg on the outer peripheral surface of the tip portion of the prepreg to be the heel body 14A. A fishing line support portion 40 is also formed on the inner surface of the thick tube portion 51. A reamed stepped portion 51a is formed on the inner surface of the distal end of the thick-walled tube portion 51, and a fitting tube portion 52 is fitted and bonded to the stepped portion 51a.
[0024]
A female screw part 52a is formed on the inner surface of the front end of the fitting cylinder part 52, and a guide cylinder part 53 is screwed into the female screw part 52a. As a result, the guide tube portion 53 is detachable from the fitting tube portion 52. The guide cylinder part 53 has a taper part 53a spreading toward the tip side on the inner surface and a step part 53b formed on the inner peripheral side of the taper part 53a. A guide ring 54 is attached to the stepped portion 53b.
[0025]
The guide ring 54 is made of a cermet ceramic molded body. The cross-sectional shape of the guide ring 54 is a curved shape that protrudes smoothly toward the center side. An arc portion 54 a is formed at the tip of the guide ring 54, and its radius of curvature R ₃ is larger than the radius of curvature R ₁ of the arcuate portion 45 of the fishing line support portion 40. The inner diameter D ₁ of the guide ring 54 is smaller than the inner diameter d ₀ of the convex portion of the fishing line support portion of the tip rod 14.
[0026]
Here, since the guide tube portion 53 with the guide ring 54 attached thereto is screwed into the thick tube portion 51 formed integrally with the bag main body 14A via the fitting tube portion 52, the guide ring 54 is damaged. However, it is only necessary to replace the guide tube portion 53 to which the new guide ring 54 is attached.
Next, in particular, a method for manufacturing the spike basket 14 will be briefly described.
[0027]
First, a release agent made of wax or the like is applied to the outer periphery of the mandrel, and a release tape made of polypropylene resin is tightly wound thereon. Next, a prepreg for forming the fishing line support portion 40 to be molded, the first to fourth layers 14 a to 14 d and the thick tube portion 51 of the top guide 18 is wound around the outer periphery of the release tape. As described above, the fishing line support portion 40 is formed by winding a tape-shaped prepreg impregnated with a resin of Tyranno fiber spirally at a predetermined pitch. The four prepreg layers 14a to 14d and the thick tube portion 51 are formed by densely winding a prepreg tape formed by impregnating a resin with carbon fiber.
[0028]
The fishing line support portion 40 and the innermost prepreg layer 14a are produced by winding a prepreg tape with reinforcing fibers oriented in the length direction of the tape. Therefore, the fishing line support portion 40 and the prepreg layer 14a are reinforced. The orientation of the fibers is along the circumferential direction of the mandrel. For the second and third prepreg layers 14b and 14c, a prepreg tape in which the reinforcing fibers are oriented in the tape width direction is used, or a prepreg sheet in which the reinforcing fibers are oriented in the longitudinal direction is used. It is produced by winding it along the axial direction. As a result, the second and third prepreg layers 14b and 14c are in a state in which the reinforcing fibers are oriented in the axial direction.
[0029]
The fourth prepreg layer 14d is produced in the same manner as the first prepreg layer 14a. The reinforcing fibers are oriented in the circumferential direction.
Thus, after the prepreg that forms the fishing line support portion 40, the four prepreg layers 14a to 14d, and the prepreg that forms the thick tube portion 51 are arranged, the outer periphery is made of polyethylene terephthalate (PET), polypropylene, or the like. A shape-retaining tape (not shown) is wound and fired by a conventional method. If the outer shape-retaining tape is peeled off after firing and the inner-side release tape is removed, a bag main body 14A with a thick tube portion 51 as shown in FIGS. 3 and 5 is obtained.
[0030]
Here, a fishing line passage 15a having a circular cross section is formed on the inner periphery of the rod main body 14A, and a spiral fishing line support portion 40 having a trapezoidal cross section is formed on the inner peripheral surface of the fishing line passage 15a. A thick cylindrical portion 51 of the top guide 18 is formed integrally with the tip of 14A.
A step cylinder 51a is formed by reaming the tip of the thick-walled cylinder part 51, a fitting cylinder part 52 created separately is inserted into the step cylinder 51a, and a guide cylinder 54 is attached to the fitting cylinder part 52 in advance. By screwing the portion 53, a spike 145 with a top guide 18 is obtained.
[0031]
In the through rod 10 configured in this way, when used, the fishing line 30 fed out from the reel 20 is supported by the fishing line support portion 40 from the fishing line introduction port 16 through the fishing line passages 15b and 15a, and is guided by the top guide 18. It will be guided by the ring 54.
In the through rod 10 having such a structure, the fishing line support portion 40 is formed inside the tip rod 14 having a small inner diameter, which tends to increase the sliding resistance due to water or the like. The sliding resistance can be prevented from increasing.
[0032]
Further, the inner wall surfaces of the intermediate rod 13 and the main rod 12 are formed as smooth surfaces, and no fishing line support portion is formed. For this reason, there is no portion where the end portions of the head rod 14 and the intermediate rod 13 collide with each other when the tip rod 14 is stored in the intermediate rod 13 and when the intermediate rod 13 is stored in the main rod 12. , Generation of sound during storage and damage to the end can be suppressed. Furthermore, reinforcing fibers are oriented in the circumferential direction in the layers constituting the inner wall surface of the intermediate ridge 13 and the original ridge 12. For this reason, the inner wall surface becomes relatively hard and the inner wall surface itself is less damaged. Therefore, the hook of the heel end portion to the inner wall surface is reduced.
[0033]
Further, since the inner diameter D ₁ of the guide ring 54 is smaller than the minimum inner diameter d ₀ of the fishing line support portion 40, it becomes difficult for the fishing line to come into contact with the fishing line support portion 40 on the tip side, and the fishing line is less likely to be damaged on the tip side of the fishing line support portion 40. Become. Even if the fishing line is in contact, the fishing line support portion 40 has the arc-shaped portion 45, so that the passage resistance is small and the fishing line is hardly damaged. Furthermore, since the radius of curvature R ₃ of the arc-shaped portion of the guide ring 54 is larger than the radius of curvature R ₁ of the arc-shaped portion of the fishing line support portion, the resistance when the fishing line passes can be reduced.
[0034]
[Other Embodiments]
(A) As shown in FIG. 7, the top guide 68 may have a fitting cylinder portion 69 fitted to the outer peripheral surface of the tip end of the collar body 14 </ b> A and a guide ring 70.
The fitting tube portion 69 is a taper-shaped resin member whose outer surface expands toward the tip side, and the inner diameter of the fitting cylindrical portion 69 is a two-stage step whose inner diameter gradually decreases from the tip side toward the heel side. Portions 69a and 69b are formed. A tip-side guide ring 70 is fitted from the tip of the fitting cylinder 69 to the inner peripheral surface of the stepped portion 69a. The guide ring 70 is formed of a cermet ceramic molded body. The guide ring 70 covers the distal end of the fitting tube portion 69, and the outer periphery of the guide ring 70 coincides with the outer periphery of the fitting tube portion 69. The cross-sectional shape of the guide ring 70 has a curved shape that protrudes smoothly toward the center side. A circular arc portion 70 a is formed at the tip of the guide ring 70, and its inner diameter D ₃ is larger than the inner diameter d ₀ of the fishing line support portion 40 of the tip rod 14.
[0035]
A guide ring 71 on the heel side is fitted into the second step portion 69 b of the fitting cylinder portion 69. The guide ring 71 on the heel side is also made of the same material as the guide ring 70 on the tip side. The cross-sectional shape of the guide ring 71 is also a curved shape that protrudes smoothly toward the center side. A circular arc part 71 a is formed at the tip of the guide ring 71, and its radius of curvature R ₄ is larger than the radius of curvature R ₁ of the arcuate part 45 of the fishing line support part 40. The inner diameter D ₂ of the guide ring 71 is smaller than the inner diameter d ₀ of the convex portion of the fishing line support portion 40.
[0036]
Here, since the fitting tube portion 69 is made of resin, the weight of the top guide 68 can be reduced. Further, since the guide ring 70 is also arranged at the tip of the fitting tube portion 69, the fishing line is difficult to contact the fitting tube portion 69, and the fitting tube portion 69 is hardly damaged even if it is made of resin. Furthermore, since the external shape of the fitting cylinder part 69 is a taper shape, a fishing line is hard to get entangled.
(B) As shown in FIG. 8, the top guide 78 may have a thick cylindrical portion 79 integrally formed on the outer peripheral surface of the tip end of the heel body 14 </ b> A and a guide ring 80.
[0037]
The thick-walled cylinder portion 79 is a member formed thicker than the heel body 14A at the tip of the heel body 14A, and a stepped portion 79a is formed on the inner surface of the tip. A guide ring 80 is fitted into the stepped portion 79a. The guide ring 80 is formed of a cermet ceramic molded body. The cross-sectional shape of the guide ring 80 has a curved shape that protrudes smoothly toward the center side. An arc portion 80 a is formed at the tip of the guide ring 80, and the radius of curvature R ₅ is larger than the radius of curvature R ₁ of the arcuate portion 45 of the fishing line support portion 40. The inner diameter D ₅ of the guide ring 80 is smaller than the inner diameter d ₀ of the convex portion of the fishing line support portion 40.
[0038]
Here, since the thick tube portion 79 is formed integrally with the rod main body 14A, the outer diameter of the top guide 78 is not so large as compared with the rod main body 14A, and the fishing line is not easily entangled.
(C) In addition to the illustrated embodiment, the structure of the through hole 10 can be configured by appropriately combining structures similar to those of a normal through hole. The structure of the reel 20, the grip portion 12, the fishing line introduction port 16, etc. can be the same as that of a normal through rod.
[0039]
(D) Of the top guide 18, the material of the fitting cylinder portion 52 and the guide cylinder portion 53 is the same material as that of the conventional top guide, and specifically, metal, synthetic resin, wood material, ceramics, etc. Can be mentioned.
(E) The material of the guide rings 54, 70, 71, 80 is preferably a material having a small friction coefficient and excellent durability, such as the cermet ceramics described above. Ceramics other than cermet ceramics, metals, and synthetic resins can also be used.
[0040]
(F) The present invention can be similarly applied to a side-by-side through rod instead of the swing rod.
[0041]
【The invention's effect】
In the penetricular rod for penetrating rods according to the present invention, the fishing line contacts with the inner periphery of the fishing line support portion having a trapezoidal cross section in the rod body, so that the fishing line can be prevented from being damaged by excessive stress. Moreover, since the inner diameter of the guide ring on the rod body side is smaller than the inner diameter of the fishing line support portion, the fishing line is less likely to come into contact with the fishing line support portion on the tip side, and the fishing line is less likely to be damaged on the tip side of the rod body. Even if the fishing line comes into contact, the fishing line support portion has an arc-shaped portion, so that the passage resistance is small and the fishing line is hardly damaged. Furthermore, since the radius of curvature of the arc-shaped portion of the guide ring is larger than the radius of curvature of the arc-shaped portion of the fishing line support portion, the resistance when the fishing line passes can be reduced.
