DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through fishing rod.

[0002]

2. Description of the Related Art When a fishing line drawn from a rear reel is introduced into an introduction hole of a fishing line guide member provided in a long hole for introducing a fishing line formed in a rod tube, the fishing line contacts the surface of the rod tube. In order to prevent the line resistance from increasing, a fishing line guide may be provided at a position higher than the rod pipe behind the introduction hole,
In this case, a holding member for holding the fishing line guide is required. In order to prevent the fishing line from being caught on the holding member, the side view shape may be set to have a bridge-shaped or mountain-shaped inclined portion. On the other hand, it is necessary to protect the fishing line guide member provided in the long hole formed in the rod tube from being damaged by collision with the outside or the like. In some cases, this is also used by legs extending the inclined portion of the holding member. The applicant of the present invention has previously applied in Japanese Patent Application No. 10-96877 to bring the leg portion close to or in contact with the guide member to close the gap where the fishing line bites into the rod tube.

[0003]

However, even with such a structure, particularly when fishing is performed with the holding member positioned below the rod pipe, that is, when a spinning reel is normally used. However, when the rod bends, the holding member of the fishing line introduction part also receives a bending force in the bending direction, and generally, the inclined part or the like is configured to set the member width in a side view to a predetermined value or more to increase the rigidity in the bending direction. ing. For this reason, the inclined portion or the like spreads the bending force by expanding in the left-right direction. However, the expansion may cause a plastic deformation, and may not return to the original state, thereby causing a gap into which the fishing line bites again. Accordingly, an object of the present invention is to prevent a fishing line from biting between a holding member and a rod tube or the like even when a fishing rod receives a strong bending force.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned object, according to the present invention, there is provided a rod tube made of fiber reinforced resin, wherein a long hole for introducing a fishing line is provided, A holding member holding a hard guide at a position distant from the tube surface is separated from the front side of the holding portion of the hard guide into left and right sides and extends forward while a pair of inclined portions approaching the elongated hole. A front end of each of the inclined portions, a leg extending substantially along a longitudinal direction of the rod pipe, and a side surface of the inclined portion, the leg, and a boundary between the inclined portion and the leg. H2, H
1, H2 ', and the widths of the inclined portion, the leg portion, and the boundary portion between the inclined portion and the leg portion in plan view are B2, B1, and B, respectively.
When 2 ′, at least B2 compared to B1 / H1
/ H2 or B2 '/ H2' is provided with a through fishing rod characterized by being large.

According to a second aspect of the present invention, a long hole for introducing fishing line is provided in a rod tube made of fiber reinforced resin, and a hard guide is held at a position behind the long hole and away from the surface of the rod tube. The holding member has a pair of inclined portions in a direction approaching the elongated hole while extending forward while being separated left and right from a front side portion of the holding portion of the hard guide, and a tip of each of the inclined portions is generally a rod. A through fishing rod having a leg extending along the longitudinal direction of the pipe, and a cover extending substantially vertically in a side view at a boundary between the leg and the inclined portion. I will provide a.

According to the first aspect, since at least one of B2 / H2 and B2 '/ H2' is larger than B1 / H1, the laterally extending permanent deformation of the boundary portion, which is a fishing line biting position, is prevented. To this end, the rigidity in the left-right spreading direction with respect to the rigidity in the vertical direction (bending direction) of the inclined portion or the boundary portion is improved as compared with the leg portions. In claim 2,
Even if the holding member is permanently expanded and deformed to the left and right when the fishing rod is bent, the cover portion is provided at the boundary in a substantially vertical direction in a side view, so that the fishing line can be prevented from biting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is a longitudinal sectional view showing the vicinity of a fishing line introduction portion of a fishing rod according to the present invention.
FIG. 3 is a side view, FIG. 3 is a top view thereof, and FIGS. 4 to 6 are detailed views of the fishing line guide member. In FIGS. A rod tube 50 made of a synthetic resin such as an epoxy resin as a matrix and reinforced with a reinforcing fiber such as carbon fiber.
Is provided with a long hole 50H.
In order to prevent direct contact with the fishing line 2, a fishing line guide member 54 having a fishing line introduction hole 54H, which is another long hole, is mounted.

A small-diameter rod pipe 52 made of the same material as described above is spliced to the rod pipe 50 in a swing-out manner.
The fishing line guide member 54 is configured to hardly protrude into the inside of the rod tube 50 so that the small diameter rod tube 52 can be stored to the rear of the fishing line guide member 54. A tail plug 60 holding a ceramic fishing line guide ring 60G is screwed into the rear end of the small-diameter rod tube, through which the fishing line 12 is inserted to reach the front end. After the end of fishing, the rod may be stored with the fishing line inserted, but at the time of the next fishing, each rod pipe is pulled out and spliced. When the small diameter rod pipe 52 is pulled out, the attached fishing line may be attached to the rod pipe 50.
A base of a brush member 64 is adhered to a lower rear portion of the fishing line guide member main body 55 in order to prevent the fishing line guide member main body 55 from being drawn into and meshed with the joint portion. When the small diameter rod pipe 52 is pulled out, the brush can sweep the surface of the rod pipe 52 and push the attached fishing line 12 toward the rear end of the small diameter rod pipe 52.

The fishing line guide member is formed so as to surround the perimeter of the long hole 50H and has a main body portion 55 made of synthetic resin.
The semi-circular hard fishing line guides G1 and G2 are adhered and fixed. In this way, the fishing line is received by the hard fishing line guides G1 and G2, which are hard to wear, at the front and rear edges of the long hole 54H, which may come into particularly strong contact when the fish catches. The fishing line guide member 54 is adhesively fixed to the main body 55. The fishing line guide member main body portion 55 may be made of rubber other than synthetic resin, and is preferably formed of a softer material than the rod tube 50 so as to have a lower rigidity than the rod tube 50, but includes the hard fishing line guides G1 and G2. May be integrally formed of ceramic. The hard fishing line guides G1 and G2 are formed of a wear-resistant member such as metal in addition to ceramics.

A hard guide ring G3 made of ceramics is disposed at a position near the rear side of the long hole 54H (or the long hole 50H) and at a predetermined height from the surface of the rod pipe. For this reason, the holding member 56 for holding this is made of a plate-like member such as stainless steel or chrome-plated metal which is not easily rusted. This member 56 extends forward from the front side of the holding portion of the hard guide ring G3, and
And a pair of inclined portions 56K extending in a direction approaching the front end of the fishing line guide member.
It has a pair of legs 56A, and a front end and a rear end
Is fixed to the rod tube 50. In addition, the threading operation is convenient, and the upper part of the long hole 54H of the fishing line guide member 54 is completely open for weight reduction.

The member 56 can be formed by pressing a plate-like member, and the thickness of the entire member is substantially constant. The angled portion holding the guide ring G3 has a drawn shape, so that the rigidity of the member 56 can be ensured even with a thin plate. Further, each of the inclined portion and the leg portion has an L-shaped cross section or a shape similar to the L-shaped cross section to secure rigidity. In the leg, the fishing line guide member main body 55 is pressed from above at the inner corner of the L-shape. Alternatively, although the cross section is flat, a pair of legs are formed in a C-shape when viewed in the longitudinal direction from the front and back of the rod pipe, and the fishing line guide member main body 55 is inclined obliquely upward. And a pair of legs may be configured to contact the fishing line guide member main body 55.

This is a modified example. As another form, it may be close to or not in contact with the fishing line guide member main body 55, or may be partially in contact with it. In the embodiment, the leg 56A is connected to the fishing line guide member 54.
Along the rear end from the front end to the rear, so that when the external force is applied via the member 56, the force applied to the fishing line guide member is smaller than when the pressing area is short. Stress concentration can be prevented and its damage can be prevented.
In addition, since the leg portion covers more than two-thirds of its length from the front end to the rear along the fishing line guide member 54, the fishing line guide member 54 can be more protected than when the pressing area is short. .

However, the fishing line guide member 5
When the leg portion of the member 56 covers the fishing line guide member 4, the fishing line guide member is protected from external force. However, the member 54 has an inclined portion in the direction approaching the fishing line guide member from the front side of the holding portion of the hard guide ring G3. Since it has 56K, as can be seen in FIG. 1, a continuous acute angle gap is generated in the lower space of the slope at the boundary between the slope and the leg. At the time of threading or during fishing, the fishing line moves in a complicated manner, so that the fishing line may be bitten into this small gap. In order to prevent this, a triangular projection integrally formed at the time of injection molding on the upper surface of the main body 55 of the fishing line guide member 54, that is, a filling portion 54T is filled on the upper surface of the fishing line guide member 54 so as to fill the acute angle gap. Provided.

The filling portion may be formed of the same resin member as the main body of the fishing line guide member, but a slightly more elastic member such as rubber is formed integrally with the fishing line guide member. When the member 56 is mounted, the member 56 may be assembled so as to be pressed slightly, so that even if the manufacturing error between the member 56 and the fishing line guide member 54 is slightly large, it is possible to prevent a gap which normally causes a line bite. Further, a filling portion may be provided on the side of the boundary portion of the member 56 by bonding or integrally forming (a cover portion). In addition, a form in which it is pushed into the gap may be used. The presence of such a filling portion also serves as a member that supports the inclined portion of the member 56.

However, apart from the case of the cover portion, if the rod is strongly bent while fishing while the holding member 56 is positioned below the rod, the inclined portion 56 of the holding member may be bent.
Although K is affected by the bending force, FIG.
, The width H2 (H2 ′) as in this example.
If it is secured to some extent, it is difficult to bend in the vertical direction. For this reason, the inclined portion tends to expand in the width direction (left-right direction) of the rod tube 50 in plan view shown in FIG. In the specific drawings disclosed in the earlier application (Japanese Patent Application No. 10-96877), the inclined portion 5 is disclosed.
The inner peripheral edge of the 6K in plan view is indicated by a two-dot chain line 56 in FIG.
H ", the width dimension is considerably smaller than the width H2. Therefore, the rigidity in the left-right direction is considerably smaller than that in the up-down direction, and therefore the stiffness expands in the left-right direction. Since the width B2 is increased to about the width H2, the expansion is prevented, so that it is prevented from expanding right and left and being permanently deformed, and as a result, it is possible to prevent the occurrence of a gap into which the fishing line bites.

If, instead of the width B2, the width B2 'at the boundary between the inclined portion and the leg is large to some extent, even if most of the inclined portion 56K is narrow, the vicinity of the boundary portion is prevented from spreading left and right. Thus, it is possible to prevent the occurrence of a gap into which the fishing line bites. Claim 1 of the present application describes such a structure for improving rigidity in the left-right direction by changing the width B1 in the left-right direction of the leg 56A to the width H1 in the vertical direction.
B2 / H2 or B2 / H2 compared to the ratio B1 / H1 divided by
2 '/ H2' is expressed as being large. In order to reduce the threading operation and line insertion resistance, the long hole 5 of the fishing line guide member 54 is used.
It is preferable to completely open the upper part of 4H, and therefore, generally, the width B1 of the leg is set smaller than the upper and lower width H1. The widths H1 and H2 in side view are generally approximately the same. The width H2 'is also substantially the same as the above unless the cover is provided.

FIG. 3 is a plan view of the inclined portion 56K of the member 56.
Even if the inner peripheral edge is thin as shown by a two-dot chain line 56H "(as in the prior application) and expanded in the left-right direction under the influence of the bending force, as shown by a two-dot chain line 56C in FIG. A cover portion 5 extending toward the center of the rod tube 50 in a side view at a boundary portion.
If 6C is provided, biting of the fishing line can be prevented. The cover portion may further extend in the front-rear direction. Preferably, the forward portion (the lower portion in FIG. 2) of the cover portion 56C is locked to the rod tube 50 and the fishing line guide member 54. That is, a groove may be provided on the surface of the rod tube or the like, and the tip of the cover may be engaged with the groove, or the cover may be screwed or riveted to the rod or the like.

Further, unlike the above-described concept, the rigidity of the inclined portion 56K of the member 56 in the bending direction (vertical direction) of the rod is reduced to facilitate bending in the vertical direction, and is flexible so as to return to its original state after bending. With this configuration, permanent deformation due to bending is prevented, and it is possible to prevent the fishing line from biting. As a specific example, the inclined portion 56K and the leg portion 56A of the member 56 are formed by an elongated plate-like portion, the width direction of the plate is set to the left-right direction (the plate thickness direction is set to the up-down direction), and approximately 90 degrees at the boundary. The legs are twisted so that the width direction of the plate is the vertical direction (the thickness direction is the horizontal direction). In the above, the description has been given based on the drawings of the embodiment having the fishing line guide member 54.
Irrespective of the presence of the fishing line guide member 54, the leg 5
6A may directly contact the rod pipe.

[0019]

As is apparent from the above description, according to the present invention, even when the fishing rod receives a strong bending force, it is possible to prevent the fishing line from biting between the holding member and the rod tube, etc. It becomes a good fishing rod.
