Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod formed by connecting a plurality of rod bodies, in particular, a base rod and a base rod connected to the tip side of the base rod in a swinging manner, and the positional relationship between them is shown. The present invention relates to a fishing rod that can be adjusted to adjust the entire length of the fishing rod.

[0002]

2. Description of the Related Art In a conventional swing-type fishing rod, a plurality of tubular rod bodies can be inserted into the rod body on the rod base side sequentially from the rod body on the tip side. When fishing, each rod body is sequentially pulled out toward the tip side, fitted and fixed, and used as one rod body. On the other hand, at the time of storage, the rod body on the tip side is sequentially stored in the rod body on the rod base side to provide a compact state.

Further, there is a conventional swing-out type fishing rod which is devised so that the positional relationship between the upper rod and the upper rod can be adjusted and the length of the entire rod can be changed for fishing.
The original rod of the fishing rod devised in this way has a first fitting female part on the inner peripheral surface of the tip end side end and a second fitting female part on the inner peripheral surface of the rod base side end. The female portion or the second fitting female portion is adapted to be fitted on the rod-side end of the top rod and the peripheral surface on the tip side, respectively. That is, in the state where the base rod is pulled out to the tip side (hereinafter referred to as "extended state"), the male fitting portion of the base rod is fitted with the first female fitting portion of the base rod, and the base rod is In the state of being inserted into the base rod (hereinafter referred to as the "stored state"), the fitting male part of the base rod is fitted with the second fitting female part of the base rod.

In this manner, the base rod and the base rod can be fitted and connected and fixed to each other in any of the "stretched state" and the "stored state", and the length of the entire rod can be changed depending on the situation. It will be possible to fish by changing.

[0005]

SUMMARY OF THE INVENTION With such a swing-type fishing rod, or with a swing-type fishing rod in which the overall length of the fishing rod can be adjusted by the mutual relationship between the original rod and the upper rod. In order to improve the mutual fitting force, the inner diameter of the fitting female portion of the base rod and the outer diameter of the top rod are precisely set. For this reason, the base rod acts like a cylinder of the piston, and the air resistance when pulling out or storing the base rod is increased, which may hinder the smooth movement of the base rod into and out of the base rod. is there.

That is, since the base rod is a rod body with a large diameter located closest to the rod base, it is formed as a tapered cylindrical body, but it is generally a rod body with a single taper rate or a small taper change. For this reason, if the diameters of the fitting female part of the base rod and the fitting male part of the top rod are precisely matched, air leakage will occur even in places other than the fitting part (diameters of both rods). Difference)
Is small, there is a possibility that the above-mentioned piston phenomenon may occur. In particular, this phenomenon is remarkable when the rod body on the tip side of the original rod has a solid rod body or a fishing line locking device.

Such a piston phenomenon between the base rod and the top rod may induce suction of water or dust from the gap of the bottom plug attached to the end of the base rod of the base rod. In addition, an unpleasant sound may be generated when the rod is taken in and out. An object of the present invention is to provide a fishing rod capable of smoothly putting a fishing rod in and out of the fishing rod.

[0008]

The fishing rod according to the first aspect of the present invention is a fishing rod for use in fishing, comprising a large-diameter rod body and a small-diameter rod body connected to the tip side of the large-diameter rod body in a swing-out manner. Is equipped with. Then, the large-diameter rod body has a fitting taper portion whose inner peripheral surface is a fitting female portion from the tip end side end to the rod base side, and a large diameter continuously extending to the rod base side of the fitting taper portion. The first taper portion has a diameter, and the second taper portion is continuous with the rod base side of the first taper portion and has a larger diameter toward the rod base side and has a smaller taper inclination than the first taper portion. Further, the small-diameter rod body has a male fitting portion at the rod-base-side end portion, which has a diameter larger than that of the other portion and can be fitted to the inner peripheral surface of the fitting tapered portion.

In this fishing rod, the large-diameter rod body and the small-diameter rod body are connected in a swinging manner, and the small-diameter rod body can be freely taken in and out of the large-diameter rod body. When fishing, pull out the small-diameter rod body to the tip side of the large-diameter rod body, and fix the male fitting part of the small-diameter rod body by fitting it to the inner peripheral surface of the mating taper part of the large-diameter rod body. To do. In addition, at the time of storage, this fitting is released and the small-diameter rod body is stored in the large-diameter rod body.

Here, the large-diameter rod body has a first taper portion in which the taper inclination increases partially, and the first taper portion has an inner diameter of the fitting taper portion and the second taper portion in the large-diameter rod body. The difference between is expanding. As a result, the diameter difference between the inner diameter of the second tapered portion of the large-diameter rod body and the outer diameter of the small-diameter rod body (in particular, the outer diameter of the fitting male portion) becomes large, and a sufficient clearance is maintained therebetween. And this clearance suppresses what is called a piston phenomenon. Further, the provision of the first taper portion partially prevents the large-diameter rod body from unduly increasing the change in taper.

The fishing rod of invention 2 is the fishing rod of invention 1, wherein
The difference between the inner diameter at the tip side end of the second taper portion of the large diameter rod body and the outer diameter of the fitting male portion of the small diameter rod body is 0.5 mm to
It is set to about 1.0 mm. In this fishing rod, the necessary and sufficient air passage to the inside of the large-diameter rod body is secured by setting the difference in the predetermined diameter within the predetermined range.

A fishing rod according to a third aspect of the present invention is the fishing rod according to the first or second aspect, wherein the large-diameter rod body has a taper ratio of 2 /
1000-4 / 1000, the taper rate of the first taper portion is 20 / 1000-30 / 1000, and the taper rate of the second taper portion is 0.1 / 1000-2.0 / 10.
00. In this fishing rod, the taper rate of each part of the large diameter rod body is set within a predetermined range. By sequentially setting the taper to this extent, the pistons of the large diameter rod body and the small diameter rod body are eliminated.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. [Overall Structure of Fishing Rod] As shown in FIG. 1, a fishing rod adopting an embodiment of the present invention includes a base rod 1, a base rod 2 connected to the tip side of the base rod 1, and a base rod. It has a middle rod 3 connected to the tip side of 2 and a tip rod 4 connected to the tip side of the middle rod 3. These base rod 1 to tip rod 4 are tapered cylindrical members formed from prepregs made 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. Note that the number of rod bodies is appropriately set depending on the required length of the entire fishing rod and the like, and is not limited to four as described above, and any number can be used.

A fishing line locking device 5 is connected to the tip end of the tip rod located closest to the tip. Then, the fishing line L is connected to the fishing line lock 5. As the fishing line lock 5, a well-known one can be used. For example, a woolen member called a “snake mouth” or a rotating ball and a rotating body are arranged inside a tubular body. An example is one in which the fishing line can be locked. As for the tip rod, a solid rod body may be used unlike other rod bodies in order to reduce the diameter.

[Structure of the base rod 1 and the base rod 2] The base rod 2 and the base rod 1 of this fishing rod can be fixed to each other in both the extended state and the stored state. The structures of the base rod 1 and the base rod 2 will be described in detail below. First, the rod 1 will be described. As shown in FIG. 2, the base rod 1 is a tubular body that is tapered so that the diameter becomes smaller toward the tip side as a whole. Then, a butt plug 6 is detachably attached to the end portion on the rod base side. A nut member 7 is provided inside the end of the base rod 1 on the rod base side.
Is disposed, and the stopper ring 8 is disposed on the inner peripheral surface on the tip side. The buttocks 6 are removably screwed onto the nut member 7.

The stopper ring 8 has a plurality of projections on the inner peripheral surface thereof, which project radially inward and extend in the axial direction, and the rod base side end portion (fitting male portion) of the upper rod 2 on the inner periphery of the projections. Two
It is adapted to be fitted to the outer peripheral surface of a). The tip end side of the protrusion may be chamfered gently. Original pole 1
In detail, each of the taper portions is partially changed as follows. That is, as schematically shown in FIG. 2, the base rod 1 includes a fitting tapered portion 10 whose inner peripheral surface is a fitting female portion from the tip end side portion to the rod base side, and the fitting tapered portion 10. A first taper portion 11 that is continuous with the rod base side and has a larger diameter toward the rod base side, and a diameter that is continuous with the rod base side of the first taper portion 11 and has a larger diameter toward the rod base side, and taper inclination from the first taper portion 11 Is smaller than the second taper portion 12, a third taper portion 13 which has a larger diameter continuously from the rod base side of the second taper portion 12 toward the rod base side and has a larger taper slope than the second taper portion 12, and a third taper portion. 13 has a fourth taper portion 14 which is continuous with the rod base side and has a larger diameter toward the rod base side and has a smaller taper inclination than the third taper portion.

The fitting taper portion 10 is a portion to which an outer peripheral surface of a fitting male portion 2a of a main rod 2 described later is fitted on an inner peripheral surface thereof. Although it depends on the overall length of the original rod 1,
For example, the axial length of the entire base rod 1 is 700 to 800 mm.
Assuming the degree is, for example, the axial length is 100
~ 150 mm, taper rate is 2 / 1000-4
/ 1000 is set.

The first tapered portion 11 is the fitting tapered portion 1.
It is a portion that expands to the rod base side as compared with 0. This part also depends on the total length of the base rod 1, etc.,
For example, based on the above assumption, the axial length is 20 to
It is relatively short, about 40 mm, and the taper rate is 20/1000.
It is set to about 30/1000. The second taper portion 12 is a portion that is smaller than the first taper portion 11 and gradually expands toward the rod base. Second taper portion 12
May be set to a straight taper with almost no change in taper. This portion also depends on the entire length of the base rod 1 and the like, but for example, based on the above assumption, the axial length occupies the main portion of the base rod 1 and is relatively 300 to 500 mm. Long, taper rate 0.1 / 1000 to 2/1
It is set as small as about 000. This taper rate is preferably about 1.0 to 1.5.

The third tapered portion 13 is the second tapered portion 1.
It is a portion that expands to the rod base side as compared with 2. Based on the above assumption, this part also has an axial length of 20 to 50.
mm, relatively short, taper ratio 30 / 1000-4
It is set to a large value of about 0/1000. Also, this third
At both axial ends of the tapered portion 13, a second tapered portion 12 and a fourth tapered portion 14 described later are respectively continuous.
A smooth curved surface may be set in the axial direction in order to maintain smooth continuity with.

The fourth tapered portion 14 is the third tapered portion 1.
It is a portion that is smaller than 3 and expands to the rod base side. Based on the above assumption, this part also has an axial length of 10 to 30.
mm is relatively short, with almost no taper ratio 0.1 / 1
It is set to about 000 to 1.0 / 1000 or as a straight taper. In the fourth tapered portion 14, the nut member 7 and the stopper ring 8 described above are arranged.

The element rod 2 will be described below. As schematically shown in detail in FIG. 3, the original upper rod 2 is a cylindrical body that is tapered like the original rod 1. The outer peripheral surface of the rod end is formed to have a slightly larger diameter than other parts,
The outer peripheral surface of the rod end is the fitting male portion 2a. Further, a bottom plug 9 may be arranged at the end of the base rod 2 on the base side of the rod, if necessary. The fitting male portion 2a is, for example, a method of partially laminating a prepreg material to increase the diameter, or a portion in which a taper change is provided at the rod base side end portion as in the case of the original rod 1. It can be formed by a method in which the diameter is increased and the diameter is increased. The outer diameter of the fitting male portion 2a is set so as to match the inner diameter of the fitting tapered portion 10 of the base rod 1 and the inner diameter of the stopper ring 7 described above while providing a taper change as necessary. (See Figure 4).

The outer diameter (φB) of the end portion of the base rod 2 on the rod base side
And the inner diameter (φA) at the tip side end of the second taper portion 12 of the base rod 1 is preferably set to 5 mm or more. Each rod body on the tip side of the upper rod 2 is provided with the same fitting portion as that of the conventional swing-type fishing rod.

In the fishing rod having such a structure, when fishing, each rod body is sequentially pulled out to the tip end side, and the rod bodies are fitted to each other in a swinging manner so that one fishing rod and a fishing line lock. Ingredient 5
Fishing line L is connected to and fishing is performed. Further, at the time of storage, the fitting of each rod body is released and the rod body on the tip side is sequentially stored in the rod body on the rod base side to make a compact state. Further, the base rod 1 and the base rod 2 should be fitted to each other not only in the state where the base rod 2 is pulled out from the base rod 1 (extended state) but also in the stored state (stored state). It is also possible to perform fishing while adjusting the length of the entire fishing rod.

That is, in the stretched state in which the base rod 2 is pulled out to the tip side of the base rod 1, the fitting male portion 2a of the base rod 2 is connected to the tip of the base rod 1 like a normal swing-type fishing rod. It is fitted and fixed to the inner peripheral surface of the fitting tapered portion 10 at the side end portion (FIG. 3).
reference). On the other hand, in the housed state in which the base rod 2 is inserted into the base rod 1, the male fitting portion 2a of the base rod 2 is inserted into the stopper ring 7 and fitted (see FIG. 4).

When the base rod 2 is put in and taken out of the base rod 1, the first taper portion 11 of the base rod 1 is divided into the fitting taper portion 10 and the second taper portion 12 of the base rod 1. The difference in inner diameter has been expanded. As a result, the diameter difference between the inner diameter of the second tapered portion 12 occupying most of the base rod 1 and the outer diameter of the base rod 2 (in particular, the maximum outer diameter at the rod base side end) becomes large, and in the meantime, Clear clearance is maintained. And this clearance suppresses what is called a piston phenomenon. Further, by providing the first tapered portion 11 partially with a relatively small axial length, it is possible to prevent the taper change from being unduly increased as a whole. To prevent such a closed piston,
It is possible to prevent an unpleasant sound from being generated when putting in and out, and to prevent water and dust from entering through the gap between the base rod 1 and the bottom plug 6.

In addition, the base rod 1 is also at the base end of the rod.
By providing the third taper portion that partially expands in diameter, a space for accommodating the nut member 7 and the stopper ring 8 can be partially formed at the rod-base-side end of the rod 1. [Other Embodiments] (a) In the above embodiment, the description is given of the type of fishing rod in which the length of the entire fishing rod can be adjusted. However, the present invention is not limited to such a type of fishing rod, and the present invention can be applied to a normal swing-type fishing rod. In this case, the third taper portion 13 to the fourth taper portion 14 can be omitted if necessary.
