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 In a through fishing rod, a fishing line guide is provided to reduce fishing line resistance and to prevent local abrasion of the rod pipe.
Japanese Patent Application Laid-Open No. 56-127032 discloses a structure in which a number of annular bodies as guides having substantially the same inner diameter are arranged inside a rod pipe. Japanese Utility Model Laid-Open Publication No. 3-67554 discloses a structure in which coil guides having substantially the same thickness are disposed inside a rod pipe.

[0003]

In the former, a large number of rings having an inner diameter sufficiently smaller than the inner diameter of the rod pipe are provided, so that when the fish is caught and wound, the fishing line remains in the rod pipe even if the rod pipe is bent. This makes it difficult for the fishing line to come into contact with the water droplets adhering to the inner surface of the rod pipe, and the winding resistance can be reduced. However, on the other hand, there is a disadvantage that the frictional resistance due to this portion is considerably large when the fishing line is thrown because the inner diameter of the ring is small.

In the latter case, the inner diameter of the coiled guide is large, and the frictional resistance at this portion during throwing is small, but the contact of the fishing line with the inner surface of the rod pipe cannot be prevented, and the fishing line resistance increases. In particular, if water droplets adhere to the inside of the rod tube, the throwing distance does not increase, and there is a disadvantage that the throwing property of the device and the accuracy of the throwing position are lacking.

[0005] Accordingly, the present invention provides a through fishing rod that improves the balance between the inner diameter of the fishing line guide ring and the inner diameter of the rod pipe in the rod pipe including the tip, and efficiently reduces the fishing line resistance during throwing. Aim.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned object, according to the present invention, three or more fishing line guide rings are provided in a rod-shaped region having a tapered front portion or a substantially constant diameter inside surface including a tip portion. Then, the ratio of the inner diameter of each fishing line guide ring to the inner diameter of the rod at that position is set to 50% or more at the tip part, less than 50% at the intermediate part, and the base part is formed larger than the intermediate part. A through fishing rod characterized in that the thickness of the fishing line guide ring in the base portion is formed to be greater than the thickness of the fishing line guide ring in the middle portion. In claim 2, the inner surface of the tip having an inner diameter of about 4 mm or less is formed as a smooth surface, and the inner surface of the tip is not provided with a fishing line guide ring except for the front and rear ends. It is formed in a tapered or stepped enlarged portion that is steeper than the spike portion, and the rear portion that is continuous with the enlarged portion has a tapered or substantially constant inner diameter. And a fishing line guide ring protruding from the fishing rod.

[0007]

According to the first aspect of the present invention, the inner spike portion of the rod tube region including the spike portion has a small inner diameter, and the fishing line guide ring is made thin to facilitate the insertion of the fishing line at the time of throwing and to reduce the insertion resistance. (Because the inner diameter of the tip is very small, the fishing line comes into contact with water adhering to the inner surface of the rod pipe regardless of the thickness of the fishing line guide ring. The fishing line resistance is about the same as when the wall is made thicker).
The opening ratio is set to 0% or more, and the middle portion behind the opening has an inner diameter larger than that of the spike portion. Therefore, it is easy to secure an opening large enough to facilitate the insertion of the fishing line at the time of throwing. Even if it is reduced to 50% or less, a sufficient opening can be ensured, the opening ratio can be reduced, and a thick fishing line guide ring can be formed. Since the inner portion at the rear is larger, the thickness of the fishing line guide ring can be made larger than that of the middle portion to prevent the fishing line from coming into contact with water droplets attached to the inner surface of the rod pipe. The opening ratio is also made larger than that of the middle portion to reduce the penetration resistance of the fishing line at the time of throwing.

According to experiments, when the inner surface of the rod pipe is wet, the fishing line resistance is smaller when the inner diameter is 4 mm or less than when the inner diameter is 4 mm or more. This is considered to be because, when the inside diameter is small, water droplets continue in the rod pipe to form a bulk, and the fishing line passes through the inside thereof, so that the fishing line is almost in a state of receiving only the viscous resistance of water. Based on this, claim 2
In the corresponding structure, it is not necessary to provide a fishing line guide ring provided to avoid contact with the inner surface of the rod or the water droplets adhering to the inner surface of the tip of the rod having an inner diameter of about 4 mm or less. In addition to reducing the insertion resistance, the rod pipe inner surface is formed smooth to reduce frictional resistance with the inner surface. This rear part is a rod pipe having a large inner diameter through the enlarged diameter part, and in order to prevent the fishing line from contacting water droplets attached to the inner surface of the rod pipe, a fishing line guide ring protruding inward is arranged. I have. In addition, even if such a projected fishing line guide ring is provided, it has a large opening and the insertion resistance is sufficiently small. Further, the enlarged diameter portion is formed in a steep taper or a stepped shape, so that the contact of the fishing line with a water droplet in this region is reduced as much as possible, and the fishing line resistance is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a side view of a fishing rod according to the present invention.
A spike rod 14 is joined to 2. Fishing line 20 unwound from the reel 18 mounted on the reel fixing device
Is a fishing line introduction guide 10A formed at the front of the former rod 10.
Through the inside of the rod tube, and is drawn out from the top guide 16 at the tip.

FIG. 2 shows a vertical sectional view of the tip rod 14. As shown in FIG.
A fishing line guide ring G8 made of ceramics or the like is held by a holding body HG such as a resin member and screwed to the rear end of the tip rod 14. Another fishing line guide ring G0 is attached to the tip of the top guide 16. In the following fishing line guide rings, both fishing line guide rings G0 and G8 are excluded. The fishing line guide ring G1 of this embodiment is
It is attached not to the inner surface but to the tip, and unlike the other nearby fishing line guide rings G2, is formed in a thick circular cross section.

The rod tube of the head rod 14 has a tapered inner surface with a tapered front, and a fishing line guide ring G of each size is formed on the inner surface.
.., G7 are provided. This tip rod 14
Are divided into three regions, that is, a head portion Z1, a middle portion Z2, and a base portion Z3 sequentially from the front. There is a relative margin in the inside diameter of the proximal portion Z3, and even if the thickness t of the fishing line guide rings G5, G6, G7 is formed to be thick, the inner diameter thereof is relatively large, and the fishing line 20 is thrown at the time of throwing. , The insertion resistance is small. On the other hand, water droplets adhere to the inner surface of the rod pipe, and if the fishing line 20 comes into contact with the water droplets, the fishing line resistance at the time of throwing increases, but the fishing line guide rings G5, G
If G6 and G7 have a predetermined thickness, almost no contact with the inner surface of the rod pipe of the approaching portion Z3 or water droplets can be prevented, and the yarn resistance at the time of throwing can be reduced.

At the tip Z1, the inside diameter is considerably small, and the fishing line guide rings G2, G3 are formed to be thin in order to secure a predetermined inner diameter with respect to the size of the fishing line 20. A fishing line guide ring G4 is provided at an intermediate portion Z2 between the tip portion Z1 and the base portion Z3, and has a thickness substantially equal to that of the fishing line guide ring G5. Each fishing line guide ring G3, G2
Each inner diameter is set so that G1 does not become much smaller than this inner diameter. That is, each thickness (the amount by which the fishing line guide ring G1 projects inward from the inner position of the rod pipe) is set.

Therefore, the insertion resistance of the fishing line 20 at the time of throwing can be reduced. In addition, in the tip part Z1, the inside diameter of the rod is very small, so that the fishing line comes into contact with water adhering to the inner surface of the rod pipe regardless of the thickness of the fishing line guide ring, and the fishing line resistance to water is small. Is about the same as the case of thickening. Therefore, since the insertion resistance of the inner diameter described above is more important than the fishing line resistance of the fishing line 20 against water, the structure of the tip portion Z1 whose opening ratio is increased to 50% or more reduces the line resistance at the time of throwing. be able to.

The percentage of the inner diameter of each of the fishing line guide rings described above with respect to the rod inner diameter at that position is shown by a line L1 in FIG. 2 and is less than 50% in the intermediate portion Z2.
The tip part Z1 is 50% or more, and the base part Z3 is formed gradually larger from the middle part. Further, as shown by line L2, the thickness of each fishing line guide ring is formed so as to be gradually thinner in the direction from the intermediate portion to the tip portion, and is set to be substantially constant in the direction from the intermediate portion to the original portion. ing. Of course, it may be formed thicker sequentially, which depends on the inner diameter of the rod pipe. In the above, the tip rod 14 is divided into three areas Z1,
Although the invention is divided into Z2 and Z3, the present invention is not limited to the most distal rod pipe (tip rod), but is applied to a rod pipe area including a tip part regardless of the presence or absence of a joint part.

FIG. 3 shows a second embodiment, in which a tip portion X1 of a tip rod 14 'has a gentle tapered tapered shape having an inner diameter of 4 mm or less, and a rear portion is formed as a steep tapered enlarged portion X2. The rear portion X3 is formed in a gentle tapered shape. Fishing line guide rings g3, g4, g5 of ceramics or the like are formed on the inner surface of the rear portion X3 so as to be formed so as to protrude inward. Accordingly, when the fishing line 20 passes through the inside of the rear portion X3, it is possible to prevent the fishing line 20 from coming into contact with water droplets adhering to the inner surface of the rod pipe.

On the other hand, the front end portion X1 is provided with fishing line guide rings g1 and g2 at the front and rear ends thereof, but is not provided except for this, and the inner surface of the front end portion is formed as a smooth surface. I have. The fishing line guide ring g2 at the rear end is provided at a position connected to the enlarged diameter portion X2. As a method for forming a smooth surface, a fluorine film or a prepreg having a high resin ratio is wound inside to form a fluorine layer or a resin layer when the rod tube 14 'is formed.

Experiments were conducted on the fishing line resistance when the inner surface of the rod tube was wet when the inner diameter of the rod tube was 2 mm, 4 mm, and 10 mm. 2) a state in which the inner surface is slightly wet, and a state in which the rod is so wet as when it is immersed in water.
Experimented on the street. The respective experimental results were 50% or less in the case of 4 mm and almost the same as in the case of 4 mm in the case of 2 mm in the former, based on the case of 10 mm. In the latter case, it was 67% or less for 4 mm and less than 50% for 2 mm.

If the inner diameter becomes large, the contact state between the fishing line 20 and water droplets attached to the inner surface of the rod tube hardly changes.
If it is larger than 0 mm, it is expected that the fishing line resistance is almost the same as that of 10 mm. Together with this experimental result, it can be seen that the fishing line resistance is smaller when the inner diameter is about 4 mm or less than when the inner diameter is larger. This is because when the inside diameter is large, about 10 mm, water droplets adhere to the inner surface, and the fishing line penetrates while contacting the water drops.However, when the inside diameter is small, the water drops continue in the rod pipe and become bulky. It is considered that this is because the fishing line passes through the line, and the fishing line is almost in a state of receiving only the viscous resistance of water.

In the through fishing rod, water enters through the winding operation of the fishing line 20 during fishing. However, a fishing line guide ring is provided in this spike region to reduce the inner diameter and increase the insertion resistance of the fishing line 20. Nevertheless, even if it is attempted to reduce the fishing line resistance without coming into contact with the water droplets on the inner surface of the rod pipe, the resistance to water is low regardless of the inner diameter of the fishing line guide ring because the water is in a bulk state, not in a state of water droplets. There is no great difference, and the fishing line resistance increases by the amount corresponding to the decrease in the inner diameter. Therefore, the structure of the tip portion X1 of this embodiment without the fishing line guide ring can reduce the fishing line resistance.

Although water droplets adhere to the inner surface of the enlarged diameter portion X2, the water droplets are easily dropped because of the sharp taper.
However, even if they come into contact with each other, the area is short and small, and does not cause a large fishing line resistance. Of course, a fishing line guide ring may be provided in this area.

Therefore, in the rod pipe having the structure shown in FIG.
Is hardly in contact with water in the form of drops, and since the inner diameter of the fishing line is as large as possible, the resistance when the fishing line is inserted is reduced.

In the above, the tip rod 14 'is divided into three regions X1,
Although the invention is divided into X2 and X3, the present invention is not limited to the most distal end of the rod pipe (tip rod), and is applied to a rod pipe area including the tip regardless of the joint. Therefore, as shown in FIG. 4, the present invention is also applied to the region where the tip rod and the second rod behind it are joined. In this case, the tip X

The fishing line guide rings g3 ', g4', etc. are the same as the fishing line guide rings g3, g4, etc. of FIG. 3, and the stepped portion X2 'is provided at the boundary with the small diameter portion for joining.
2 'is provided. Of course, a top guide 16 as shown in FIG. 1 and a fishing line guide ring g1 as shown in FIG. 3 are provided at the tip of the tip X1 '. Furthermore, the step-like portion X2 'in this example may be formed in a sharply tapered shape as shown in FIG.

[0023]

As is apparent from the above description, according to the present invention, since the balance between the inner diameter of the fishing line guide ring in the rod tube including the tip and the inner diameter of the rod tube is improved, the fishing line resistance at the time of throwing is reduced. It is possible to provide a fishing rod that can be reduced in size. Therefore, the throw distance is extended.
