Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called "middle threading rod" in which fishing line from a reel is inserted through the inside of a rod body.

[0002]

2. Description of the Related Art A conventional general fishing rod is constructed by sequentially connecting a plurality of rod bodies having a fishing line passage into which a fishing line can be inserted, in a swing-out type or a splicing type. For example, a reel sheet to which a reel can be attached is formed on the base rod located closest to the hand side, and a fishing line introduction port for introducing fishing line from the reel to a fishing line passage inside the rod body on the tip side of the reel sheet. Is formed. Further, a top guide is provided at the tip end of the tip rod located closest to the tip.
Then, the fishing line from the reel attached to the reel seat is guided from the fishing line introduction port to the inside of the rod body, sequentially inserted through each rod body to reach the top guide on the tip side, and is led out to the outside from the top guide. Become.

Regarding such a fishing rod, the flexibility and flexibility of the tip rod located closest to the tip end is extremely important. This is because, when a fish hits the end of the fishing line, the tip rod reacts sharply to the movement of the fish and serves as an antenna for notifying the fisherman of this. For this reason, the tip rod is made into a thin and tapered rod body having a small diameter in order to improve flexibility and flexibility, and is manufactured from a relatively soft and elastic material.

[0004]

As described above, the tip rod has been devised in various ways so as to react sensitively when a fish catches it. However, simply devising the tip rod in such a way that it is rich in soft flexibility is not sufficient to detect the reaction of the fish. In order for the fisherman to be able to recognize the reaction of the tip rod satisfactorily, it is preferable that the most visible part of the tip side of the tip reacts partially and sharply. For this reason, the conventional tip rod is a tapered tubular body whose diameter is reduced toward the tip side so that it is bent more toward the tip side.

However, satisfactory results have not been obtained even with such conventional tip rods. That is, in the conventional tip rod, when the fish actually hits the device, the fishing rod was swung up and the fishing line was wound up, and when a large force was applied from the fishing line to the tip rod,
The rod body suddenly greatly bends from a position (see point A in FIG. 5: for example, a position of about 300 to 400 mm from the tip end side end) that is considerably deviated from the tip end side end to the rod base side without bending from the tip end side end for a while. You can see the phenomenon that The bending from the middle part in the longitudinal direction of such a tip rod is
The fisherman cannot respond to the delicate reaction such as when the fish showed an interest in the trick, and the reaction is slow, and the fisherman cannot easily recognize the reaction.

Therefore, there is a demand for the development of a tip rod in which the tip side is more sensitive and sensitive. An object of the present invention is to provide a hollow rod having improved reactivity of the tip rod, particularly, reactivity of the tip side end portion.

[0007]

[Means for Solving the Problems] A hollow fishing rod according to the first aspect of the present invention is a hollow fishing rod formed by connecting a plurality of fishing rod bodies having a fishing line passage through which a fishing line is inserted. A tip rod having a straight taper portion that is located closest to the tip side and has a taper that does not change from the tip end side to the rod base side, and a tapered portion that increases in diameter toward the rod base side adjacent to the rod base side of the straight taper portion. Is equipped with.

[0008] The tip rod of this centering rod is adjacent to the base of the rod when a force is exerted on the tip rod of the fishing line led out from the end on the tip side by force from the fish and a load is applied from the fishing line to the tip rod. The straight taper portion, which has a relatively smaller diameter than the taper portion, bends significantly as compared with the taper portion. Then, the tip end on the tip side partially reacts sensitively to the reaction from the delicate mechanism.

A second aspect of the present invention is the first aspect of the present invention, wherein the straight taper portion has an axial length of 100 to 100.
It is 150 mm. With the tip rod of this middle-strand rod, the straight taper portion provided in a predetermined range is sufficiently bent, and the fisherman can easily recognize the reaction when the fish is tackled. Invention 3 through rod is the invention 2 through rod,
The taper of the taper part is 1.5 / 1000 to 3/1000
Is.

By setting the taper within a predetermined range, the taper portion is sufficiently bent as compared with the straight taper portion. Invention 4 is a hollow rod according to Invention 1, wherein
Adjacent to the rod base side of the taper portion, there is further another rod base side straight taper portion, the axial length of the straight taper portion is 100 to 150 mm, and the axial length of the taper portion is 650 to 800 mm. The axial length of the rod-side straight taper portion is 150 to 200 mm.

By further providing the rod-base-side straight taper portion on the rod-base side, it is possible to set the taper ratio of the taper portion located at the center in the longitudinal direction to be larger. The difference in taper between the straight taper portion on the tip side and the taper portion is increased, and the partial bendability of the straight taper portion on the tip side is further emphasized.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] A first embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a centering rod adopting the first embodiment of the present invention includes a base rod 1 and a base rod 2 connected to the tip side of the base rod 1.
And a middle rod 3 connected to the tip side of the base rod 2 and a tip rod 4 connected to the tip side. These rods 1
The tip rod 4 is a tapered tubular member formed of a prepreg obtained by impregnating carbon fiber, glass fiber or the like with a synthetic resin. The top rod 2 to the tip rod 4 are sequentially inserted into the rod body on the rod base side from the tip side so that they can be inserted and removed freely, and are connected in a so-called swinging manner. However, the number of rod bodies is appropriately set according to the required length of the entire fishing rod and the like, and is not limited to four as described above, and an arbitrary number can be used.

The base rod 1 has a reel seat 5 on which a reel (not shown) can be detachably mounted, and a tail plug 9 is detachably mounted on the rod base end. Further, a fishing line introducing port 6 for inserting a fishing line from the reel therein is formed on the outer peripheral surface of the tip side. A fishing line introducing guide 7 for guiding the fishing line to the fishing line introducing port 6 is mounted near the fishing line introducing port 6.

On the other hand, the inside of each of the upper rod 2 to the tip rod 4 is a fishing line passage through which a fishing line is inserted. On the inner peripheral surface of the fishing line passage, a fishing line supporting protrusion or the like formed continuously in a spiral shape in the axial direction may be formed to reduce the contact area between the fishing line and the fishing line passage. A top guide 8 is detachably attached to the tip end side of the tip rod 4. Then, the fishing line from the reel is inserted from the fishing line introducing port 6 into the fishing line passage,
After being sequentially sent to the tip side, they are led out from the top guide 8.

As shown in detail in FIG. 2, this tip rod 4
Is a tapered tubular body as a whole, but in detail,
It has a two-stage structure of a straight taper portion X whose diameter does not change in the axial direction from the tip end side portion, and a taper portion Y which is continuous with the rod base side and whose diameter increases toward the rod base side. The axial length of the straight taper portion X depends on the axial length of the entire tip rod 4, but is about 100.
It is preferable to set it in the range of about 150 mm. The purpose is to ensure sufficient flexibility of the tip rod 4 in such a range. On the other hand, the taper portion Y is 1.5 / 1
It is a tapered portion of about 000 to 3/1000.
In the tip rod 4, a predetermined fitting portion is formed at the rod end so as to fit the middle rod 3 at the rod end in a swinging manner. A portion of the end portion where the taper does not change may be formed as a fitting portion.

The tip rod 4 of this two-stage structure is prepared by, for example, preparing a core material provided with a predetermined straight taper portion and a taper portion, and winding the necessary prepreg material around the outer periphery of the core material and firing it. Can be manufactured in. As the prepreg material, it is possible to use a relatively soft carbon fiber or glass fiber arranged in a bias shape and impregnated with a thermosetting resin. This prepreg material can be set to have a substantially constant wall thickness by winding the same material regardless of whether it is a straight taper part or a taper part.

In such a fishing rod, as described above,
Each rod body is successively pulled out to the tip side to form one fishing rod, and the fishing line from the reel is used by sequentially inserting it into the fishing line passage inside the rod body. When a fish is applied to a device connected to the tip of the fishing line, a force is sequentially applied to the rod body from the top guide 8 side of the tip rod 4 via the fishing line, and the rod body is bent.
At this time, in the tip rod 4, the straight taper portion X at the tip end portion is bent more remarkably because the diameter is relatively smaller than that of the taper portion Y adjacent to the tip side (see FIG. 3). ). Then, such a partial bending of the tip end side portion informs the fisherman of the subtle movement of the device.

[Other Embodiments] As shown in FIG. 4, the tip rod 14 may have a three-stage structure. That is, the tip rod 14 has a straight taper portion X whose diameter does not change in the axial direction from the tip end portion, and a taper portion Y which is continuous with the rod base side and whose diameter increases toward the rod base side. It has a three-stage structure consisting of a rod-side straight taper portion Z which is continuous to the rod-side and whose diameter does not change even when reaching the rod-side.

The axial length of the straight taper portion X depends on the axial length of the entire tip rod 4, but it is preferably set in the range of about 100 to 150 mm as in the above embodiment. On the other hand, the tapered portion Y
The taper becomes larger than that of the above-described embodiment by the amount of forming the rod-side straight taper portion Z. It depends on the axial length, but when the axial length of the tapered portion Y is set to about 650 to 800 mm, 2.5 / 100
It is preferable to form a taper portion of about 0 to 4/1000. The axial length of the rod-side straight taper portion Z can also be set arbitrarily, but in order to make the overall condition of the tip rod 14 good, it is preferably about 150 to 200 mm.

In the hollow rod having the tip rod 14 as described above, the difference between the straight taper portion X and the taper portion Y is further emphasized, and the tip side end of the tip rod 14 partially and sharply reacts.

[0021]

With the fishing rod according to the present invention, the reactivity of the tip side end of the tip rod is sufficiently improved, and the fisherman can recognize the delicate movement of the tackle.
