DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for connecting rods to each other.

[0002]

2. Description of the Related Art A conventional fishing rod is generally used as a single fishing rod by sequentially connecting a plurality of tapered cylindrical rods made of a material such as carbon fiber reinforced resin. Here, the rod bodies of the fishing rod are connected by a connection structure called a swing type or a parallel type. For example, in a fishing rod of the draw-out type,
The pole bodies on the tip side are sequentially connected so as to be housed inside the rod body on the pole base side. The rod-side outer peripheral surface of the tip-side rod body is a fitting male part, and the tip-side inner peripheral surface of the rod-side rod body is a fitting female part. The male fitting portion is fitted to the female fitting portion while being pulled out from the rod body at the base of the rod, and is connected and fixed.

[0003]

As described above, in the conventional fishing rod, when the rod bodies are connected to each other and fixed, the rod bodies are overlapped with each other at a connecting portion (for example, a fitting male portion and a fitting female portion). As a result, the thickness of the portion is doubled. And in such a part where the rod bodies overlap and become thick, the flexibility of that part is naturally inferior to other parts, and there is a possibility that the continuous bending condition of the entire fishing rod may be impaired. .

Further, when the rods are fitted together, the rods may be too strongly fitted and fixed in some cases, and thereafter it may be difficult to release the connection between the rods. An object of the present invention is to provide a connecting structure of a rod that can prevent sticking of the rods without impairing the flexing condition of the fishing rod.

[0005]

A connecting structure according to a first aspect of the present invention is a structure for connecting a rod body constituting a fishing rod used for fishing, and has a fitting female portion on an inner peripheral surface on a tip side. A rod body and a tip side rod body having a fitting male portion which can be fitted and fixed to the fitting female portion on the outer peripheral surface of the rod base side, and a hole penetrating in the radial direction in the fitting male portion is formed. Become.

In this connection structure, the fitting male part of the tip side rod body is fitted to the fitting female part of the rod base side rod body and connected and fixed. Here, a hole is formed in the fitting male part so as to penetrate the tip side rod body in the radial direction, and so-called meat stealing is partially performed. Thereby, the overlapping portion at the time of connection between the tip-side rod body and the rod-side rod body is reduced as much as possible, and a decrease in the degree of partial bending of the rod body is reduced. Further, the contact area between the fitting male part and the fitting female part can be reduced to prevent sticking of the rod bodies, which contributes to weight reduction.

A connecting structure according to a second aspect of the present invention is the structure according to the first aspect of the present invention, wherein a plurality of holes are formed in the tip-side rod body in the fitting male portion so as to be circumferentially separated. In this case, a plurality of holes are formed in the fitting male portion so as to be spaced apart in the circumferential direction, and it is possible to further reduce a decrease in the degree of partial bending of the rod body.

A connecting structure according to a third aspect of the present invention is the structure according to the first or second aspect, wherein the rod-side rod body further has a hole penetrating in a radial direction in the fitting female portion, and is fitted with the fitting male portion. At positions where the holes of the mating female part are displaced in the circumferential direction, markings are given to the rod-side rod body and the tip-side rod body, respectively.

In this connection structure, holes penetrating in the radial direction of the tip-side rod body and the rod-side rod body are formed not only in the male fitting part but also in the female fitting part. Overlapping parts can be reduced. When the holes of the male fitting part and the female fitting part overlap each other at the same position, problems such as easy entry of dust into the strength surface and the rod body may occur, but the markings provided on each match. Thus, by making the rod-side rod body and the tip-side rod body coincide with each other in the circumferential direction, the holes can be prevented from overlapping each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] A first embodiment of the present invention will be described below with reference to the drawings.

[0011] A fishing rod employing the first embodiment of the present invention comprises:
As shown in FIG. 1, a former rod 1, a former rod 2, a middle rod 3, and a head rod 4 are sequentially connected to the tip side of the former rod 1 in a swinging manner. Each rod body is a tapered cylindrical member made of a prepreg material in which carbon fiber or glass fiber is impregnated with a synthetic resin.

A predetermined fitting male part and a fitting female part are formed on each rod body, and the rod bodies are connected and fixed by fitting these. For example, as shown in FIG. 2, in the former rod 1 and the former upper rod 2, the inner peripheral surface of the tip end side of the former rod 1 is slightly smaller in diameter than other parts to form a fitting female part 1 a, The outer peripheral surface of the rod base side end of the former upper rod 2 is slightly larger in diameter than other parts to form a fitting male part 2a.
The inner diameter and the outer diameter are adjusted so as to match each other.

As shown in FIGS. 2 and 3, the fitting male portion 2a extends in the axial direction near the center in the axial direction so as not to reach the rod-side end, and is spaced apart in the circumferential direction. A plurality of holes 10 penetrate the upper rod 2 in the radial direction. The hole 10 is formed, for example, after a predetermined prepreg material is wound around a core material, fired, and subjected to a surface treatment or the like to form the original rod 2.

In this embodiment, three holes 10 are provided at intervals in the circumferential direction, but the number of holes 10 can be set arbitrarily. For example, as shown in FIGS. 4 and 5, it is also possible to provide two places and four places in the circumferential direction.

The same connection structure is used in relation to other rods. In this fishing rod, the former upper rod 2 is pulled out to the tip side of the former rod 1, the fitted male part 2a is fitted to the fitted female part 1a, and is connected and fixed. Here, a hole 10 is formed in the fitting male portion 2a so as to penetrate the upper rod 2 in the radial direction, and so-called meat stealing is partially performed. As a result, the portions (the male fitting portion 2a and the female fitting portion 1a) that overlap when the former upper rod 2 and the former rod 1 are connected to each other are connected.
Of the fishing rod) is reduced as much as possible to reduce a decrease in the degree of partial bending of the fishing rod. This allows for smooth operation of the fishing rod.

Further, since the contact area between the male fitting portion 2a and the female fitting portion 1a at the time of fitting is reduced, sticking of the rod bodies can be prevented, and detachment becomes easy. It also contributes to weight reduction. Second Embodiment Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

In the former rod 1 and the former upper rod 2 of the fishing rod employing the second embodiment of the present invention, similarly to the first embodiment,

This is the fitting male part 2a. The inner diameter and the outer diameter are adjusted so as to match each other.

As shown in FIG. 6, the fitting male portion 2a extends in the axial direction near the center in the axial direction so as not to reach the end on the rod base side, and has a plurality of holes 10 spaced apart in the circumferential direction. Penetrates the former pole 2 in the radial direction. Furthermore, this fitting female portion 1a also extends in the axial direction near the center in the axial direction so as not to reach the end on the tip side, and a plurality of holes 10 penetrate the main rod 1 in the radial direction at intervals in the circumferential direction. are doing.

A marking 20 is provided on each of the tip end of the original rod 1 and the tip end of the original upper rod 2. For example, the marking 20 is provided by surface painting, a seal, or the like. The markings 20 are shown on the former pole 2 and the former pole 1 so that the hole 10 of the former pole 1 and the hole 10 of the former upper pole 2 do not coincide with each other in the circumferential direction.

The former rod 1 and the former rod 2 have been described.
The same connection structure is used in relation to other rods. In this fishing rod, the former upper rod 2 is pulled out to the tip side of the former rod 1, the fitted male part 2a is fitted to the fitted female part 1a, and is connected and fixed. At this time, the connecting and fixing are performed at circumferential positions where the markings 20 coincide with each other. Here, the fitting male portion 2a is formed with a hole 10 that penetrates through the upper rod 2 in the radial direction, and has the same operation and effect as the first embodiment.
In addition, the markings 20 can also prevent the holes 10 of the former pole 2 and the holes 10 of the former pole 1 from being aligned with each other in the circumferential direction, and can prevent the fitting force or the strength from being unduly reduced. .

[Other Embodiments] (a) Instead of the above embodiment, the hole 10 may be formed only on the fitting female portion 1a side of the original rod 1.
