BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through fishing rod,
In particular, it relates to the structure of the fishing line introduction portion.

[0002]

2. Description of the Related Art Conventionally, a fishing line introduction guide provided with a guide hole is loaded in an opening of a fishing line introduction portion for guiding a fishing line from the outside to the inside of a rod tube in a through fishing rod.
As shown in FIG. 3, the thickness of the introduction guide 8 is set to be larger than the thickness of the rod tube 9. Inner peripheral surface 9
It is formed so as to protrude from a. This is a fishing line L guided into the rod tube 9 by the guide hole of the introduction guide 8.
This is to prevent the rod from contacting the inner peripheral surface of the rod tube 9 so that a thread path is not formed in the rod tube.

When the thickness of the rod tube 9 is set to be small from the viewpoint of reducing the weight of the fishing rod, even if the inner edge 8a of the introduction guide 8 protrudes from the inner peripheral surface of the cylinder of the rod tube 9, Thus, the fishing line L can be introduced into the rod pipe in a state where the introduction angle is reduced. When the thickness of the rod tube 9 is set to be thin,
It was inferior in strength and was not suitable for fish with strong pulling or heavy fish. Therefore, if the thickness of the rod pipe is increased, such a problem can be avoided. However, the thickness (fitting depth) of the corresponding introduction guide 8 must be set to be proportionally large.

[0004]

However, as described above, if the thickness of the introduction guide 8 is set to be large, the introduction angle of the fishing line L guided from the outside of the rod tube to the inside becomes steeply inclined. As shown in FIG. 3, the fishing line L has two edges: an upper end (outer) edge on the entry side of the introduction guide 8 and an inner edge.
It comes into a bent state when it comes into contact with some places, and the yarn resistance increases. In such a bent state, the frictional resistance of the line when the fishing line L moves in the horizontal direction of the rod (the direction perpendicular to the longitudinal direction, that is, the direction perpendicular to the paper surface) becomes extremely large, and the winding operation of the fishing line is performed. And adversely affect the release operation. To prevent this, refer to Introduction Guide 8
The guide hole may be formed long in the longitudinal direction. However, if the guide hole is long, foreign substances such as seawater and dust easily enter the inside of the rod pipe, which is not preferable. Further, when the inner edge 8a of the introduction guide 8 is configured to protrude from the inner peripheral surface of the rod tube 9, in the case of a projecting rod, when the small diameter rod tube is closed, the inner peripheral portion 8a of the rod guide 9 is closed. There were not a few inconveniences such as collision with the inner edge of the small-diameter rod tube protruding from the surface and damaging the small-diameter rod tube and the introduction guide 8.

The present invention has been proposed in view of the above-mentioned problems of the prior art. Even if the guide hole of the introduction guide is set to be small so as to prevent the invasion of foreign matters and the like as much as possible, the present invention can be applied during winding or during winding. A comfortable operability can be obtained by reducing the frictional resistance to the fishing line during feeding, and when the small-diameter pipe is closed in the large-diameter pipe having the introduction guide, the rear end of the small-diameter pipe is caught by the introduction guide. It is an object of the present invention to provide a fishing rod that does not collide or collide.

[0006]

According to the present invention, a fishing line introduction hole for introducing a fishing line from the outside to the inside of a rod tube is formed, and a fishing line guide having a guide hole formed in the fishing line introduction hole is mounted. In a fishing rod, a wall thickness and an outer diameter dimension of the rod pipe around the fishing line introduction part are formed larger than other parts (the rod pipe main body), and a wall surface defining the fishing line introduction hole, and a cylinder inner peripheral surface. At least a portion of the side opening corresponding to the fishing line path is formed so as to be inclined corresponding to the fishing line path, and at least the rod tip side of the inner end portion of the introduction guide is located closer to the inner peripheral surface of the rod pipe main body. It is characterized in that it is formed so as to be located radially outward.

[0007]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the following description, for convenience of explanation, a description will be given on the assumption that a guide rod is attached to an original rod pipe (large-diameter rod pipe) by taking a swing rod as an example.

As shown in FIG. 1 and FIG. 2, a through fishing rod according to an embodiment of the present invention is composed of an original rod tube 1 and a small diameter rod tube 2 (middle rod tube, head tube) joined thereto. Be composed.
The original rod tube 1 has a reel leg fixing device 10 for fixedly attaching the reel R and a grip portion 11, and a fishing line led out from the reel R at a predetermined position on the joint portion side with the small-diameter rod tube as the distal end side. The fishing line introduction part 3 which guides the inside of the rod pipe is formed.

The portion where the fishing line introduction portion 3 of the original rod tube 1 is formed has a thick-walled shape formed to be larger than the outer diameter of the other portion (the rod tube main body). Note that, in the present embodiment, the inner diameter of the original rod tube 1 is set to the joint portion 15 with the small diameter rod tube 2.
, Except for the same dimension over the entire length in the longitudinal direction. Hereinafter, the thick portion is referred to as the thick portion 16.
, And the portion of the rod tube main body is referred to as a thin portion 17. Thin part 1
7, the thickness of the thick portion 16 is t2, and the thickness of the thick portion 16 is t2.
The wall thickness ratio when the wall thickness is t3 is t2 ≧ t
3> t1. The thickness t2 of the thick portion 16 is preferably about 1.5 times the thickness t1 of the thin portion 17.

A fishing line introduction hole 18 is formed in the thick portion 16 of the original rod tube 1 as an opening for communicating between the inside and the outside of the rod tube. The fishing line introduction hole 18 expands as it goes toward the inner peripheral surface side of the original rod tube 1 with the fitting wall surface portion 18a that mounts (fixes) the introduction guide 4 on the outer peripheral surface side of the original rod 1 in a fitted state. It is defined by the inclined wall portion 18b as shown in FIG. The angle of inclination of the inclined wall portion 18b on the rod tip side is
The angle is set so as to be substantially parallel to the approach angle. That is, the reason for forming the inclined wall portion 18b in this way is to prevent the fishing line L from contacting the original rod tube 1,
This is to prevent contact resistance from occurring and to prevent the rod tube from forming a thread path. In the illustrated example, an inclined wall surface portion 18c symmetrical to the inclined portion on the tip side is also formed on the rod tail side. However, in the present invention, the opening on the rod pipe inner peripheral surface side is formed so as to have an inclined wall surface part over the entire opening so that the opening gradually increases in diameter toward the rod pipe inner peripheral surface. Is also good.

In this embodiment, the inclined wall portions 18b, 1
The meeting position between the fitting wall portion 8c and the fitting wall portion 18a is the center position of the thick portion, but the present invention is not limited to this.

The guide hole 4a of the introduction guide 4 attached to the fishing line introduction hole 18 formed in the thick portion 16 has a long hole shape extending in the rod extending direction. It is not limited to the illustrated one. That is, the guide hole 4a may be inclined along the extending direction of the fishing line L. The inner edge (lower end in the drawing) of the introduction guide 4 is located inside the inclined wall surface 18a of the introduction hole 18 and is formed so as not to protrude into the inner peripheral surface of the rod pipe.
This is to prevent the fishing line L from contacting the lower edge of the introduction guide 4. Therefore, the lower end edge of the introduction guide 4 may be formed so as to be located radially outward from the inner peripheral surface of the rod pipe body over the entire area, or only the corresponding portion or the vicinity of the fishing line L path may be rod-shaped. You may comprise so that it may be located in the radial direction outer side from the inner peripheral surface of a pipe main body. The material of the introduction guide 4 is not particularly limited, but ceramic, metal, hard plastic, or the like is used.

A guide member 6 having a guide ring 6a is fixedly wound around the outer periphery of the fishing line introduction portion.
In addition, the method of fixing the guide member 6 to the outer peripheral surface of the original rod tube 1 is not limited to the pin-winding fixing method. Needless to say, it is good. The guide member 6 may be detachably attached.

In FIG. 2, at the rear end of the small diameter rod tube 2,
The plug 21 is detachably attached.
Is provided at the center with a guide ring having a guide hole formed therein.

[0015]

According to the present invention, since the thickness of the fishing line introduction portion of the fishing rod is increased, the strength can be improved even if the introduction hole is formed. In addition, the rod tip side portion of the inner edge portion of the introduction guide, that is, the portion corresponding to the fishing line path side does not protrude from the inner peripheral surface of the cylinder, and at least the fishing line path of the wall portion defining the introduction hole of the rod pipe. Since the corresponding portion is inclined so as not to obstruct the path of the fishing line, the fishing line does not bend and the contact resistance does not increase when the fishing line is wound or released. Further, according to the through fishing rod of the present invention, if the inner end portion of the introduction guide is configured not to protrude to the inner circumferential surface of the original rod tube over the entire circumference, the small diameter rod tube can be used as the original rod. The rear end does not collide with the lower edge of the introduction guide when displacing in the tube cylinder, so that no damage is caused thereby.
