Description

The present invention relates to a fishing rod, and more particularly to a fishing rod used in boat fishing and having a feature in the original rod portion.

Recent fishing rods have a structure capable of exhibiting preferable performance depending on the target fish. Among fishing rods used in boat fishing, for example, a fishing rod targeting sea bream is required to have lightweight and highly flexible fishing rod characteristics. In other words, the sea bream is very cautious, and if you use a thick fishing line or if the bait attached to the gimmick moves unnaturally, it will affect the fishing result. It is desirable that the fishing rod as a whole be flexible and supple so that it does not move naturally (movement that bounces due to the elasticity of the rod).

For example, on page 114 of Non-Patent Document 1, a fishing rod for boats (Riomaster; registered trademark) suitable for sea bream fishing is disclosed, and a reel is attached so that the entire fishing rod can be bent flexibly. The structure is such that the original rod can be sufficiently bent. In order to make the main rod flexible, it is preferable that the diameter is small. Specifically, considering weight reduction, if the diameter is about 7 to 10 mm, the main rod can be sufficiently bent. It is possible. In addition, the above-mentioned fishing rod is equipped with a front grip, a mid grip, and a rear grip so as to have good grip during actual fishing, and these grips have a good grip. For example, a foaming material made of synthetic resin such as EVA or urethane, or a natural material such as cork is used.

By the way, the above-mentioned fishing rod may be detachably attached to and operated from the fishing rod holder attached to the ship's edge, and in such a usage mode, a rod clamp (also referred to as a clamp head) for the fishing rod holder is used. Must be clamped between the mid grip and the rear grip where the rod rod is exposed. In this case, as described above, the diameter of the original rod is reduced, and the holding state of the rod clamp is not stable (especially, when a heavy electric reel is attached, the rod rod tends to rotate and is stable. Since the fishing rod cannot be held), as shown in FIG. 6, a tubular spacer 120 having a larger diameter is attached to the original rod 100 between the mid grip 110 and the rear grip 130, and a tubular spacer 120 having a larger diameter is attached to the surface of the portion. By covering with a carbon pipe 140 that has been subjected to a treatment such as surface coating, the rod clamp can be stably sandwiched.

A foaming material (highly foaming material) is used for the tubular spacer mounted between the mid grip and the rear grip described above so as not to increase the weight. However, since the foam material has a large dimensional error, there is a problem that eccentricity is likely to occur between the mid grip and the rear grip located on both sides in the axial direction. As described above, since the mid grip and the rear grip are also made of a foamable material having a large dimensional error, it is difficult to secure the concentricity between these grips and the spacer, and therefore, in practice, When these members are attached to the original rod, an eccentric state may occur at the boundary portion between the carbon pipe and the mid grip and the boundary portion between the carbon pipe and the rear grip, which may cause a sense of discomfort. For this reason, conventionally, in order not to cause such a sense of incongruity, the dimensional error is taken into consideration in advance, and the diameter difference between the mid grip and the rear grip is increased with that of the carbon pipe at the boundary portion between the mid grip and the rear grip. I try to absorb.

As a result, the wall thickness of the mid grip and the rear grip becomes thick, and the weight of the original rod portion increases. Further, if the diameters of the mid grip and the rear grip are increased, the diameter difference between the mid grip and the rear grip becomes large, so that a good appearance (slender appearance) cannot be obtained.

The present invention has been made by paying attention to the above-mentioned problems, and is a fishing rod having a large diameter original rod with a spacer interposed between the grips to be gripped and held, and the weight can be reduced. The purpose is to provide a fishing rod with a good appearance.

In order to achieve the above object, the fishing rod according to the present invention is attached to the original rod rod, and a spacer is arranged between the front grip and the rear grip, each of which is made of a flexible material, and the spacer is provided. A tubular body is press-fitted upward to increase the diameter between the grips, and the spacer is formed by extending the front grip to the rear side, and the tubular body is attached to the extended extension portion. It is characterized by being adhered.

The fishing rod with the above configuration has a spacer between the front grip and the rear grip when the diameter of the rod (former rod) is increased. It is possible to secure the concentricity of the spacer. For this reason, the occurrence of misalignment between the two is prevented, the front grip does not need to be unnecessarily thickened, the weight can be reduced as a whole, and the boundary portion where the front end portion of the spacer shifts to the front grip portion. A slender appearance can be obtained without unnecessarily swelling. In addition, the front grip is press-fitted from the base end side of the original rod, but when the front grip is press-fitted, the spacer is also press-fitted as it is, improving workability and using a thin-walled spacer. realizable.

Further, the spacer disposed between the grips in the present invention can also be formed by extending the grip to the front side after being press-fitted into the original rod rod.

According to the present invention, with respect to a fishing rod having a main rod rod having a large diameter with a spacer interposed between grips to be gripped and held, weight reduction can be achieved and a good appearance can be obtained.

Hereinafter, embodiments of the fishing rod according to the present invention will be described. Since the present invention is characterized in that the diameter between the grips attached to the original rod rod is increased, the original rod rod portion will be illustrated and described in the following embodiments. Therefore, as a fishing rod, the number of rod rods connected and the structure of rods connected to each other are not limited.

1 and 2 are views showing a first embodiment of the present invention, FIG. 1 is a partial cross-sectional view showing the configuration of a main rod portion, and FIG. 2 is a mid grip and a rear grip shown in FIG. It is a partial cross-sectional view which shows the structure between.
In the present embodiment, the original rod 5 constituting the fishing rod 1 is configured as a tubular member, and as is known, a prepreg sheet in which reinforcing fibers are impregnated with a synthetic resin is wound around a core metal and heat-treated. It is formed by curing the synthetic resin and then decentering it. The outer peripheral surface of the original rod 5 is formed in a straight shape along the axial direction, and the diameter thereof is formed in the range of about 7 to 10 mm, and the load acts on the rod tip side of the prepreg sheet. At that time, a structure in which the original rod itself can be bent is used. Then, the following constituent members are press-fitted into the straight rod 5 from the rear end side indicated by the arrow D1 and adhered to and fixed to the surface thereof.

The constituent members that are press-fitted and fixed to the original rod rod 5 are a front grip 10, a cylindrical reel seat 20, a mid grip 30, and a rear grip 40 from the rod tip side.
In the present embodiment, three grips are press-fitted and fixed to the original rod rod, and a portion between the mid grip 30 and the rear grip 40 is an exposed portion of the original rod rod, and a spacer and a tubular body are attached thereto. The diameter is increased. Therefore, the front grip specified in the claims means the mid grip 30, and the rear grip means the rear grip 40.
The three grips 10, 30, and 40 that are press-fitted and fixed to the original rod 5 are formed of a material that is lightweight and comfortable to grip, for example, a flexible foam material such as EVA, cork, or the like. NS. When a foaming material is used, it is preferable to use a foaming material having low foaming so that a certain degree of strength can be maintained.

The front grip 10 is formed so as to gradually reduce its diameter as it shifts to the front end side, and is fixed so that the reel seat 20 abuts on the rear end. The configuration of the reel seat 20 is not limited, but the main body 21 which is tubular and has the reel leg mounting surface 21a, the fixed hood 22 provided on the rear side of the main body 21 and fixing the reel legs, and the main body. A nut 23a for screwing into a male screw portion 21b provided on the front side of the 21 is provided, and a moving hood 23 for tightening and fixing the reel leg is provided. That is, the reel leg of the reel is placed on the reel leg mounting surface 21a, the rear side of the reel leg is fitted to the fixed hood 22, and in this state, the tightening nut 23a of the moving hood 23 is rotated to operate the moving hood 23. The reel is attached / detached by approaching / separating the fixed hood 22 from the fixed hood 22.
The reel seat 20 may have a finger hook 25 or the like formed on the side opposite to the reel leg mounting surface, or the front side may be a fixed hood and the rear side may be a moving hood.

The mid grip 30 is press-fitted and fixed to the rear side of the reel seat 20.
The tip of the mid grip 30 is in contact with the fixed hood 22 of the reel seat, and the diameter of the mid grip 30 is gradually reduced from that portion to the rear side (this diameter-reduced region is an exposed portion and is gripped). Part 31). The mid grip 30 is formed with an extension portion (rear extension portion) 32 that extends (extends) toward the rear side integrally with the grip portion 31. The extension portion 32 is formed in a straight shape so as to be press-fitted in close contact with the outer peripheral surface of the original rod 5, and the diameter of the original rod 5 is increased between the mid grip and the rear grip 40. It has a function as a spacer.

After the mid grip 30 is press-fitted and fixed from the rear, a tubular body 35 is press-fitted and fixed to the outer peripheral surface of the extension portion 32. The tubular body 35 is lightweight and preferably has high strength because a rod clamp is sandwiched therein, and one made of fiber reinforced resin is used. That is, the diameter of the original rod rod can be efficiently increased by thickening the extension portion 32 to secure the diameter and attaching a lightweight (thin wall thickness) and high-strength tubular body 35. It is possible. In this case, the wall thickness t of the tubular body 35 may be formed to be about 0.5 to 1.0 mm, and the surface of the tubular body 35 is surface-treated with the same pattern as the outer surface of the original rod 5. It may be applied, or a surface treatment having a different pattern may be applied.

As described above, the mid grip 30 on which the extension portion 32 is formed is formed of a foamable material such as EVA. The mid grip 30 is formed with a through hole into which the original rod 5 is fitted along the central axial direction, and on the outer peripheral surface thereof, an exposed grip portion 31 and a grip portion 31 that is exposed to the rear. A tubular extension portion 32 that extends and is adhered to the tubular body 35 is integrally formed. In the mid grip 30 having such a shape, for example, a through hole having substantially the same diameter as the diameter of the original rod 5 is formed in the above-mentioned foam material formed in a cylindrical shape, and then the through hole portion is chucked. The surface may be processed so that the grip portion 31 and the extension portion 32 are formed. Alternatively, the grip portion 31 and the extension portion 32 can be formed by centerless processing or the like.

The wall thickness T of the extension portion 32 of the mid grip 30 is not particularly limited, but when processing an effervescent EVA, it can be formed in a range of about 2 to 4 mm, and the diameter of that portion can be formed as a spacer. It is possible to increase the diameter by about 4 to 8 mm. Further, the tubular body 35 to be press-fitted can be attached to the boundary portion between the grip portion 31 and the extension portion 32 of the mid grip 30 so that the tubular body 35 can be positioned and flush with the surface of the tubular body 35. It is preferable to form a step portion (stop portion) 34 corresponding to the wall thickness of the tubular body 35.

The step portion 34 may be configured such that the end surface of the tubular body 35 formed and press-fitted in the direction perpendicular to the axial direction comes into contact with the surface, or an inclined surface whose diameter gradually increases toward the tip side. It may be composed of a stepped surface that expands in diameter in a stepped manner. In the case of the latter configuration, it is possible to form a slight gap G (adhesive pool) between the tubular body 35 and the end face thereof. That is, when the adhesive is applied and the tubular body 35 is press-fitted, the adhesive applied to the inner surface of the tubular body 35 is squeezed and accumulated in the gap G which becomes the adhesive pool, which exerts an anchor effect. It is possible to effectively prevent the peeling of the tubular body.

In the above configuration, when the outer diameter of the extension portion 32 is d and the inner diameter of the tubular body 35 is d1, it is preferable to form the extension portion 32 and the tubular body 35 so that d ≧ d1. When the tubular body 35 is press-fitted, the extension portion 32 is elastically deformable, so that the extension portion 32 can be press-fitted even if the outer diameter of the extension portion 32 is the same as or slightly larger than the inner diameter of the tubular body 35. Further, since the difference in diameter between the two members is small, misalignment is less likely to occur, the state of adhesion of the tubular body 35 to the outer peripheral surface of the extension portion 32 is stable, and peeling between the two members is suppressed.

Further, at the boundary portion between the grip portion 31 and the extension portion 32 of the mid grip 30 (the portion where the step portion 34 is formed), the outer diameter of the boundary portion P1 at the rear end portion of the mid grip 30 is set to D, and the tubular body. When the outer diameter of 35 is D1, it is preferable to form the grip portion 31 and the tubular body 35 so that D ≧ D1.
That is, by setting the outer diameter at the rear end of the grip portion 31 to be the same as or slightly larger than the outer diameter of the tubular body 35, the transition region from the tubular body to the grip portion is made substantially uniform. It is possible to finish the appearance beautifully (it becomes a slender appearance). In addition, since the shape has such a slender appearance, the weight of the mid grip can be reduced. Further, by making the diameters of the two substantially the same, a large step is not generated at the boundary portion between the grip portion 31 and the extension portion 32, so that the stress concentration when the main rod 5 is bent is minimized. It is possible to reduce the rigidity gap between the two.

Then, after the tubular body 35 is press-fitted into the extension portion 32, the rear grip 40 is press-fitted into the main rod 5. In the present embodiment, the extension portion 32 and the tubular body 35 are formed to have the same length, and after the tubular body 35 is press-fitted, the front end edge of the rear grip 40 is press-fitted so as to come into contact with the end face thereof. It is fixed. In this case, when the outer diameter at the boundary portion P2 at the front end of the rear grip 40 is D2, it is preferable to form the rear grip so that D2 ≧ D1 with the outer diameter D1 of the tubular body 35. .. That is, by setting the outer diameter at the front end of the rear grip 40 to be the same as or slightly larger than the outer diameter of the tubular body 35, the transition region from the tubular body to the rear grip is substantially flush with the mid grip portion. It can be shaped and the appearance can be beautifully finished (it becomes a slender appearance).

According to the above configuration, since the extension portion 32 serving as the spacer is integrally formed with the mid grip 30, it is possible to secure the concentricity between the two, and therefore, as in the conventional case, The mid grip 30 does not need to be thickened, the weight can be reduced, and the appearance can be made slender and beautifully finished. Further, unlike the conventional method, a simple tubular spacer is not press-fitted into the main rod, but an extension portion (spacer) integrated with the mid-grip 30 is press-fitted. Therefore, when the mid-grip is press-fitted, the spacer is also integrated. Since it is press-fitted, the press-fitting operation can be easily performed even if the extension portion is made thinner. That is, in the conventional spacer, when the wall thickness is thinned, there is no stiffness at the time of press-fitting the main rod, and the press-fitting work cannot be easily performed, or it is necessary to make the wall thickness thick to some extent. No such problem arises.

Further, as in the conventional configuration, in the configuration in which a spacer separate from the front grip is press-fitted, when the original rod 5 is greatly bent, the distance between the rear end edge of the mid grip and the spacer is widened, so that the spacer is released from the mid grip. There was a problem of peeling (cracking), but in the above configuration, the spacer is integrated with the same material as the front grip, so even if the original rod bends significantly, such peeling will occur. There is no such thing. Further, since such peeling is unlikely to occur, it is possible to prevent poor adhesion and abnormal noise.

The fishing rod 1 provided with the above-mentioned original rod 5 is used for boat fishing, and the outer diameter of the original rod is thin and lightweight, and the original rod itself has a structure that is easily bent. As described above, since the midgrip 30 and the extension portion 32 which is the spacer are concentric, the outer diameter D at the rear end boundary portion P1 of the midgrip and the tubular body 35 which is press-fitted into the extension portion The diameter difference of the outer diameter D1 of the above can be reduced as much as possible. Specifically, even if D is set to 15 mm and D1 is set to 14 mm and the diameter difference between the two is set to 1 mm or less (one-sided wall thickness is 0.5 mm or less), there is a step that deteriorates the appearance between the two. It can be prevented from occurring. Further, since the tubular body 35 can be press-fitted, the outer diameter D can be further reduced, whereby the surface of the tubular body 35 and the surface of the midgrip 30 can be made substantially uniform as described above. It will be easy to do.

Further, in the fishing rod of the above-described form, a rod clamp (not shown) is attached to the portion of the tubular body 35 between the mid grip 30 and the rear grip 40, and during actual fishing, the angler can move from the reel seat 20 to the mid. The area of the grip 30 is gripped and held by one hand, and the rear grip 40 is gripped and held by the other hand. Therefore, the maximum outer diameter of each grip is secured to be about 25 mm so as to be easy to grip, but as described above, the boundary portion with the tubular body 35 can be reduced in diameter (D is 18 mm in the conventional configuration). Therefore, the diameter difference between the maximum outer diameter of the grip and the outer diameter at the boundary portion can be made larger than before (conventionally, the diameter difference was about 7 mm, but in the above configuration, at least A diameter difference of 9 mm or more can be secured). As a result, in each grip, the taper in the region from the boundary portion to the maximum outer diameter can be made tighter than in the conventional case, so that the grip structure can be easily gripped and is not slippery.

FIG. 3 is a partial cross-sectional view showing the second embodiment of the present invention and showing the configuration between the mid grip and the rear grip of the original rod.
In this embodiment, an extension portion 42 extending forward so as to be press-fitted into the inner surface of the tubular body 35 of the above-described embodiment is formed on the front end side of the grip portion of the rear grip 40. Therefore, the tubular body 35 is formed so as to be slightly longer than the extension portion 32 of the mid grip 30.

In this case, if the extension portion 42 of the rear grip 40 is made too long, the stiffness becomes weak when press-fitting into the inner surface of the tubular body 35, so that the length thereof is secured to be 5 mm or less, preferably about 2 to 3 mm. I just need to be there. As described above, since the spacer (extension portion 32 of the mid grip) can accurately secure the concentricity with respect to the central axis of the original rod 5, the extension portion 42 is formed on the rear grip 40. , This portion can be easily press-fitted into the inner surface of the tubular body 35, so that it is not necessary to increase the diameter of the rear grip as in the mid grip. That is, since the rear grip 40 can also be finished to have a slender appearance, it is possible to reduce the weight and improve the appearance.

4 and 5 show a third embodiment of the present invention, FIG. 4 is a partial cross-sectional view showing the configuration of the original rod portion, and FIG. 5 is between the mid grip and the rear grip shown in FIG. It is a partial cross-sectional view which shows the structure.
In the above-described embodiment, various constituent members are press-fitted from the rear side to the original rod 5 as shown by the arrow D1 in FIG. 1 and fixed by adhesion. However, as shown by the arrow D2 in FIG. , The configuration may be such that various constituent members are press-fitted from the front side.

Therefore, in the present embodiment, the rear grip 40 is formed with an extension portion (extension portion 42A) extending toward the front side, and this extension portion 42A is used as a spacer. Further, the tubular body 35 is press-fitted into the extension portion 42A from the front side, and then the mid grip 30, the reel seat 20 and the front grip 10 are press-fitted in this order and fixed by adhesion.
In such a configuration, the original rod 5 does not need to have a straight shape, and can be formed into a tapered shape that gradually reduces in diameter toward the tip side. Further, a cap 60 for closing the through hole of the original rod rod (rear grip) is attached to the base end portion of the original rod rod 5. For this cap, a flange or the like is formed radially outward from the outer surface of the original rod rod, and the edge of the rear grip 40 to be press-fitted first is applied to the flange to fix the position. You may do so.

Even with such a configuration, it is not necessary to increase the diameter of the rear grip and the mid grip as in the above embodiment, the weight can be reduced as a whole, and the appearance can be beautifully finished. ..

Even in such a configuration, as in the embodiment shown in FIG. 3 described above, an extension portion 32A extending rearward is formed in the mid grip 31, and this portion is press-fitted into the inner surface of the tubular body 35. Alternatively, as shown in FIG. 2, the mid grip may be applied to the end edge of the tubular body without forming an extension portion.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be variously modified.
In the above configuration, the original rod 5 is configured as a tubular body, but may be configured as a medium entity. Further, the spacer may be arranged between the grips of the portion where the rod clamp for the fishing rod holder is bounded, and the grips attached to the original rod rod may be two places. Further, the shape, length, material, etc. of each grip that is press-fitted into the original rod and fixed by adhesion can be appropriately deformed.
