Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod for jigging (fishing rod), and more particularly to a structure of a butt portion of the rod.

[0002]

2. Description of the Related Art Recently, sea fishing has become popular on a fishing boom, and boat fishing, in particular, is carried out offshore, and therefore has a real pleasure that cannot be enjoyed on land. Among boat fishing, jigging fishing is popular until it has become a sport today because it allows you to enjoy a realistic fight with large fish. When catching fish by jigging fishing, the point of fishing is to use a jig (prototype of lure) as bait and repeatedly perform a rod operation that gives a series of actions to the jig while scratching a fishing rod (rod).

For this reason, the jigging rods used must be as easy to handle as possible, and new rod products with improved structures and functions are being put on the market one after another. Recently, many rods of this type are made of a single relatively short rod pipe (a hollow rod pipe R1 is used in FIG. 7). At the same time, the rod operation during jigging can be easily performed. Also, in jigging fishing, fishing rods for the purpose of using PE lines have become mainstream,
By shortening the fishing rod, it became possible to easily lift the jig even if a heavier jig was dropped to a deeper point (for example, more than 200 m).

[0004] The jigging rod A is usually composed of a blanks portion 2 formed on the rod tip side and having a thread guide, and a bat portion 1 formed on the rod end side (FIG. 7).
reference). The butt portion 1 has a reel seat portion 3 for attaching a reel to the outside of the rod tube, and a grip for securely gripping the rod at the front and rear positions (rod end side, rod end side) of the reel sheet portion. (4, 5). FIG.
As shown in (1), the butt portion has the rod tube in common with the blanks portion, and the wall thickness of the rod tube increases toward the rod end. Since the butt portion 1 has the reel seat portion as described above, the thickness of the rod tube is larger than that of the blank portion, and the butt portion 1 has a structure with high rigidity.

[0005] By the way, the fishing rod absorbs the load (pull) of the fish by bending the rod tube, so that even a large fish can be caught. However, since the bat portion 1 includes the grip portions (4, 5) and the reel seat portion 3, a certain length is required. The proportion of the length is of course shorter. For this reason, the load at the time of fishing is received by bending the short blanks portion 2 of the rod A, and the shorter the blanks portion 2 is, the smaller the load that can be withheld. At this time, the butt portion hardly bends because of high rigidity,
As a result, a fulcrum is formed in a boundary region between a portion having a high flexural rigidity (butt portion 1) and a portion having a low flexural rigidity (blank portion 2), and the flexure changes extremely (in addition, the flexure changes)
The position of the largest deflection change is indicated by arrow a).

[0008] That is, as schematically shown in FIG. 8, a bending fulcrum comes near the tip end side of the rod tip side grip portion 4. In such a state, the portion where the load is concentrated is near the hand holding the grip portion, and the load on the arm is large. In addition, the concentration of stress at the fulcrum of the deflection may cause breakage of the rod.

[0007]

SUMMARY OF THE INVENTION The present invention has been made based on such a technical background, and aims at solving those problems. That is, an object of the present invention is to provide a jigging rod that can withstand a larger load, reduce the burden on anglers, and is excellent in operability. It is an object of the present invention to provide a jigging rod that is not biased toward the center.

[0008]

Means for Solving the Problems The present inventors have conducted intensive studies on such problems, and as a result,
Surprisingly, it has been found that the above-mentioned conventional problems can be solved by imparting flexibility to the butt portion, and the present invention has been completed based on this finding.

That is, the present invention resides in (1) a jigging rod comprising a butt portion and a blank portion, wherein the butt portion has flexibility.

(2) A jigging rod comprising a butt portion and a blanks portion, wherein the jigging rod has flexibility in a region other than the reel seat portion of the butt portion.

(3) A jigging rod in which a butt portion is provided with a hollow rod tube extending from a blank portion, and a reinforcing rod is mounted at a position corresponding to a reel seat portion of the hollow rod tube.

(4) A hollow rod tube having a butt portion extended from the blanks portion, a reinforcing rod is inserted into a region of the hollow rod tube in the reel seat portion, and the hollow rod tube is connected to the reel sheet portion. From the jigging rod which becomes gradually thinner toward the rod end.

(5) A jigging rod having a solid rod pipe having a butt part extended from the blanks part, and a reinforcing rod externally inserted at a substantial position of a reel seat part of the solid rod pipe. Exists.

Further, (6) a hollow rod tube whose butt portion is extended from the blank portion is provided, and the area of the reel seat portion of the hollow rod tube is made thicker, and then gradually thinner toward the rod end side. And a jigging rod that gradually becomes thinner toward the blanks portion.

The present invention can also adopt a configuration in which two or more selected from the above 2 to 6 are combined as long as this object is met. Since the present invention has the above configuration, it is possible to provide a rod for jigging which is excellent in rod operation. Further, it is possible to provide a rod for jigging in which deflection is not extremely biased partially.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a jigging rod according to the present invention will be described below with reference to the drawings.
Note that the same reference numerals are used to refer to substantially the same parts as those of the conventional rod described in FIG.

[First Embodiment] FIG. 1 is a view schematically showing an entire rod according to a first embodiment of the present invention. FIG. 2 is an enlarged view of the butt portion according to the first embodiment of the present invention. FIG. 3 is a diagram schematically showing a state in which the rod is bent.

It should be noted that the fishing rod (hereinafter referred to as "rod A") here is a dedicated rod used for boat fishing, particularly a jigging rod A for fishing using a jig.
As shown in FIG. 1, the rod A here is formed from a single short hollow rod R1, so that a light weight effect can be sufficiently expected and the rod can be easily operated. .

The rod A comprises a blanks section 2 formed on the rod tip side and having a thread guide, and a butt section 1 formed on the rod end side. The butt portion 1 of the rod A has a hollow rod tube R1 extending from the blanks portion 2 in common.

The bat portion 1 is provided with a reel seat portion 3, and an area adjacent to the reel seat portion 3,
That is, the grip portions (4, 5) for gripping the rod A are provided at the front and rear positions (the rod tip side and the rod bottom side) of the reel seat portion 3. Here, the material of the hollow rod tube R1 is made of, for example, carbon prepreg, and preferably has an elastic modulus of 24,000 k from the viewpoint of bending.
Those having a range of gf / mm ² or less are preferably used.

By the way, in the present invention, the butt 1
This is the main feature in that a bendability (flexibility) is given to the. More specifically, it has a structure in which a region other than the reel sheet portion of the bat portion 1 is actively bent (bent) (this will be described in detail later). First, the reel seat portion 3 is assumed to have sufficient rigidity in consideration of the stability of mounting the reel. As shown in FIG. 2, a hollow rod tube R <b> 1 common to the butt portion 1 and the blanks portion 2 has the same diameter and the same thickness in both portions, but rigidity is given to the corresponding position of the reel seat portion 3. Reinforcing rod 6 is mounted (inserted).

That is, the reinforcing bar 6 is set to have the same length as the reel seat 3 and is inserted at a position where the reel seat 3 is attached. With such a structure, the area where the reel seat portion 3 is attached (the area of the reel seat portion 3) has high rigidity, and the area where the rod tip side grip portions 4 on both sides are attached (the pole tip side grip portion). Area 4) and the area where the rod-side grip section 5 is attached (the area of the rod-side grip section 5) have lower rigidity and tend to bend. That is,
In the butt section 1, the area other than the reel sheet section has flexibility.

Here, as the material of the reinforcing member, it is preferable to use a material such as carbon prepreg similar to the above-mentioned rod tube R1 or a metal having higher rigidity.
Further, the reinforcing rod 6 may be a hollow rod or a solid rod, and the form is not limited. By the way, in the rod A of this embodiment, as shown in FIG.
, The deflection of the rod A is hardly biased, and a uniform bending as a whole is formed.
By imparting flexibility to the butt portion 1 in this manner, the peak of bending does not come near the tip end side of the rod tip side grip portion 4 as in the related art (see FIG. 8), and the load is concentrated. Without this, rod breakage is also prevented.

[Second Embodiment] FIG. 4 is an enlarged view showing a butt portion according to a second embodiment of the present invention. What is different from the first embodiment is a region where the rod-side grip section 5 is attached (rod-side grip section 5).
Is that the thickness of the hollow rod tube R1 gradually becomes thinner from the reel seat portion 3 toward the rod end.

Here, in order to reduce the thickness of the rod tube of the rod side grip portion 5, the inner diameter is constant and the outer diameter is reduced. However, it is naturally possible to make the outer diameter constant and make the inner diameter smaller. In this embodiment,
Since the rigidity of the region where the rod-side grip portion 5 is attached (the rod-side grip portion 5) is lower, the portion is easily bent.

[Third Embodiment] FIG. 5 is an enlarged view of a butt portion according to a third embodiment of the present invention. The difference from the first embodiment is that a solid rod pipe is used. As shown in the figure, a solid rod pipe R2 common to the butt section 1 and the blanks section 2 has the same diameter.

At a corresponding position of the reel seat portion 3, a hollow reinforcing rod 6 for providing rigidity is attached (externally inserted). Due to the reinforcing rod 6, the area where the reel seat 3 is mounted (the area of the reel seat 3) has high rigidity, and the area where the rod-side grip 4 is mounted (the area of the rod-side grip 4). ) And the area where the rod-side grip section 5 is attached (area of the rod-side grip section 5)
Has low rigidity and is easily bent.

[Fourth Embodiment] FIG. 6 is an enlarged view showing a butt portion according to a fourth embodiment of the present invention. In this embodiment, in the area of the butt section 1, the thickness of the solid rod pipe at the corresponding position of the reel seat section 3 is increased. And the rod side grip section 5
The thickness of the rod pipe gradually decreases from the reel seat portion 3 toward the rod end.

Here, the outer diameter is gradually reduced in order to reduce the thickness of the rod tube of the rod side grip portion 5. Similarly, the thickness of the rod tube of the rod tip side grip portion 4 is gradually reduced from the reel seat portion toward the rod tip side. Here, in order to reduce the thickness of the rod tube at the rod tip side grip portion, the outer diameter is gradually reduced.

However, in these cases, it is of course possible to make the rod as thin as possible by gradually increasing the inner diameter of the rod tube at the rod end side grip part 5 or the rod tip side grip part. Also in this embodiment, portions other than the reel sheet portion are easily bent, and the flexibility of the bat portion 1 is guaranteed.

Although the present invention has been described above, the present invention is not limited only to the embodiment, and it goes without saying that other various modifications can be made without departing from the essence of the present invention.

For example, the present invention is not limited to a jigging rod, but may be applied to a rod composed of one rod tube used for other purposes, such as a lure rod. Further, it is not always necessary to use a common hollow rod tube or solid rod tube in which the butt portion extends from the blanks portion, and the butt portion and the blanks portion may have separate rod tubes. In such a case, it is necessary to devise such that the thickness of the connecting portion of the rod pipe at the rod tip side grip portion does not increase.

Further, the reinforcing bar 6 may be set to be longer than the reel sheet 3 or may be extended before and after a substantial position where the reel sheet 3 is attached. In this case, the reinforcing rod 6 is formed so as not to form a fulcrum of bending at both ends of the reinforcing rod 6.
It is preferable that both ends are formed to have gradually smaller diameters or thinner walls. As a result, it is possible to smooth the deflection of the entire rod without disturbing an extreme change in the deflection, to disperse the load applied to the rod, and to concentrate the stress on both ends of the reinforcing rod and to break the rod. Can be prevented.

[0034]

As described above, according to the jigging rod of the present invention, when the rod is bent, both the butt portion and the blanks portion are bent, so that the bending force is dispersed and concentrated at one place. Never do. Therefore, unlike the related art, since a large bent portion does not come near the portion that grips the grip portion, the burden on the arm is reduced. Further, by dispersing the bending force over the entire rod, concentration of the load can be avoided, breakage or the like can be prevented, and a larger load can be endured.
