Description

[Detailed explanation of the invention] (Industrial application field) This invention is mainly used for fishing rods used for sweetfish fishing.
Specifically, the present invention relates to a fishing rod whose overall length can be adjusted.

(Prior Art) In general, a fishing rod for sweetfish fishing consists of a hand-side rod body, a tip, and a plurality of intermediate rod bodies. The intermediate rod bodies are each pulled out to the outside, and a fishing line is attached to the tips of the fishing rods by a predetermined length longer than the entire length of the fishing rod.

By the way, when fishing for sweetfish using the above-mentioned fishing rod, when attaching the fishing line to a predetermined length longer than the entire length of the fishing rod, the tip side of the fishing line must be further forward than the rod end of the rod body on the hand side. As a result, when catching a hooked ayu along with a decoy ayu by grasping the bottom of the rod body on the hand side, it is difficult to pull the ayu upward from the water surface. There was a problem in which the fish often ran out of sweetfish and missed the catch.

In other words, if the length of the fishing line is approximately the same as the total length of the fishing rod, it will be easier to catch the sweetfish that has caught. When exchanging decoy ayu while holding the tail, it is difficult to exchange the decoy ayu because the length of the fishing line is too short.

Therefore, as shown in Japanese Utility Model Application Publication No. 53-135392, an auxiliary rod body is conventionally fitted around the outer periphery of the hand side rod body so as to be able to advance toward the rear with respect to the hand side rod body. A first fitting portion is provided on the proximal outer circumference of the proximal rod body and the distal inner circumference of the auxiliary rod body, and the first fitting portion is fitted when the auxiliary rod body advances, and the distal end portion of the proximal rod body is provided. A second fitting part is provided on the outer periphery of the auxiliary rod body to fit into the inner periphery of the distal end of the auxiliary rod body when the auxiliary rod body is retracted, and a second fitting part is provided on the inner periphery of the proximal end of the auxiliary rod body when the auxiliary rod body is retracted. A length-adjustable fishing rod has been proposed in which a conical holding member into which the inside of the proximal end of the proximal rod body is fitted and supported is fixed.

(Problem to be Solved by the Invention) However, in this conventional fishing rod, the holding member is formed into a conical shape that becomes smaller in diameter toward the front from the part fixed to the inner peripheral surface of the auxiliary rod, and the tapered outer surface In addition, since the proximal edge of the proximal rod body is arranged to abut linearly, the holding member can only eliminate the wobbling of the proximal rod body in the radial direction; The member could not prevent the auxiliary rod from moving in the advancing direction.

In other words, in the conventional fishing rod, the fitting length of the second fitting part is increased without providing a fitting length on the outer surface of the holding member, and the auxiliary rod body is advanced at this second fitting part. The holding member prevents movement in the radial direction, and the holding member only prevents rattling in the radial direction. Therefore, when a load is applied to the fishing rod and the rod body is deformed, the degree to which the fitting force of the second fitting part increases, and as a result, the second fitting part becomes larger.
When the fitting force of the fitting part becomes too large and a load is applied, it is difficult to advance the auxiliary rod body immediately, which delays the retrieval of hooked sweetfish. , the fish will be brought into the shore, and the auxiliary rod body will have to be advanced with great force, so when advancing, the rod body on the tip side will move vertically more than the rod body on the hand side. There was a problem that the sweetfish would easily swing and lose the hook, and the sweetfish would often be missed.

Furthermore, since the holding member is fixed to the inner circumferential surface of the auxiliary rod body, if there is a dimensional error in the inner diameter of the proximal end of the auxiliary rod body, the rod element formed into a hollow, gently conical shape may be damaged. If there is a dimensional error in the inner diameter of the proximal end of the auxiliary rod body due to an error in the cutting position when cutting both ends of the body to form the auxiliary rod body, this dimensional error may cause the holding member to be attached to the auxiliary rod body. There have been problems in that it has not been possible to attach the holding member reliably, or it has been impossible to attach the holding member to the auxiliary rod body at all.

The present invention was devised in view of the above problems, and its main purpose is to adjust the overall length of the fishing rod by advancing and retracting the auxiliary rod body from the hand side rod body. The auxiliary rod body can be advanced immediately even when the auxiliary rod body is hooked, and if a load is applied to the fishing rod with the auxiliary rod body retracted, the rod body on the hand side will not wobble. Another object of the present invention is to prevent the occurrence of dimensional errors in the rod body when adjusting the length of the fishing rod short by retracting the auxiliary rod body. In addition to being able to effectively maintain the adjusted state adjusted to a short length, the holding member for holding the retracted auxiliary rod body can be easily and reliably opposed to the base of the proximal rod body regardless of the size of the rod body. The point is to allow it to be installed in the desired position.

(Means for solving the problems) As shown in the embodiment of the drawings, the fishing rod of the present invention has an auxiliary rod body 2 having a butt plug A on the proximal end side on the outer periphery of the rod body 1 on the hand side. Fitted into the proximal side rod body 1 so as to be able to extend toward the rear, and on the proximal outer circumference of the proximal side rod body 1 and the distal side inner circumference of the auxiliary rod body 2,
A first fitting part 7 that fits when the auxiliary rod body 2 is advanced is provided on the outer periphery of the proximal rod body 1, and a first fitting part 7 is provided on the outer periphery of the proximal rod body 1. A second fitting part 8 that fits around the circumference is provided, and the butt plug A is made of a flexible material, has a fitting length extending in the length direction of the rod body, and has a second fitting part 8 that fits around the rod body. It has a fitting inner circumferential surface 5a into which the proximal outer circumferential surface of the rod body 1 is fitted, and when the auxiliary rod body 2 is retracted, the auxiliary rod body 2 is fitted in the radial and longitudinal directions with respect to the proximal rod body 1. Attaching a holding member 5 that retains the movement of the holding member 5, and supporting the outer circumferential surface of the holding member 5 opposite to the fitting inner circumferential surface 5a on the proximal end side of the auxiliary rod body 2,
The auxiliary rod body 2 is attached to the tip side of the hand side rod body 1.
It is characterized in that the proximal rod body 1 forms a non-shuttle part 13 that is exposed to the auxiliary rod body 2 when the rod body 1 is moved backward and held by the holding member 5.

(Function) By advancing and retracting the auxiliary rod body 2 fitted onto the outer periphery of the hand side rod body 1, the overall length of the fishing rod can be adjusted, while the fitting inner circumferential surface 5 of the holding member 5
Since a has a fitting length that extends in the length direction of the rod body, the auxiliary rod body 2 retreats when no load is applied.
This not only prevents the proximal end of the proximal rod 1 from wobbling, but also allows the auxiliary rod 2 to be kept from moving in the advancing direction. The length of the fitting at the second fitting portion 8 can be shortened, that is, the holding force can be weakened. As a result, even if the rod bodies are deformed when a load is applied to the fishing rod, the fitting length of the second fitting portion 8 can be shortened, so the degree of increase in the fitting force will not increase so much. Therefore, even if the fitting force of the second fitting part 8 on the distal side increases when a load is applied, the increase is
Since the size can be made smaller than when the holding member 5 is not provided on the base side, the auxiliary rod body 2 can be easily advanced even when a load is applied to the fishing rod. Since the non-cancelled part 13 is provided on the front side of the body 1, the auxiliary rod body 2 can be easily advanced by grasping or pinching the non-clinical part 13. Therefore, even when a load is applied to the fishing rod, the auxiliary rod body 2
It is possible to immediately advance the ayu, and the sooner the sweetfish can be taken in, the more
In rock fishing, it is possible to catch a fish without it entering the shore, and furthermore, the auxiliary rod body 2 can be advanced instantly, so when advancing, the rod body on the tip side can be swung vertically. The auxiliary rod body 2 can be advanced without causing the fish to fall, and the more the fish can be taken in without losing sight of the sweetfish.

Moreover, the holding member 5, which holds the proximal rod body 1 by the fitting inner circumferential surface 5a, has an outer circumferential surface opposite to the fitting inner circumferential surface 5a on the proximal end side of the auxiliary rod body 2. Therefore, when a radial load is applied to the proximal end of the proximal rod body 1 using the distal second fitting part 8 as a fulcrum due to the load applied to the fishing rod, the holding member 5 Since only one radial side portion thereof is pressed against the carrier side and compressed, the amount of movement of the proximal rod body 1 in the radial direction due to the load is very small. In other words, the proximal rod body 1 moves in the radial direction by the amount that one radial side portion of the holding member 5 is compressed in the thickness direction. Since the holding member 5 is only compressed in the radial direction, that is, the thickness direction, the amount of compression is small, and therefore, even if the proximal rod body 1 moves by this amount of compression, the amount of movement is small. It doesn't move so much that it rattles. Therefore, even though the holding member 5 is flexible, it is possible to effectively prevent the auxiliary rod body 2 on the proximal end side of the hand side rod body 1 from rattling, and it can be used repeatedly. Also, it is possible to avoid damage to the holding member 5 due to the load in the radial direction and cracking of the proximal opening of the proximal rod body 1.

Further, the holding member 5 having the fitting inner circumferential surface 5a is
Since it is made of a flexible material, even if there is a dimensional error in the outer diameter of the proximal end due to cutting of the proximal rod 1, the auxiliary rod 2 will not be affected by this dimensional error. This makes it possible to maintain movement in the radial and longitudinal directions with respect to the proximal rod body 1.

(Example) The illustrated fishing rod is a fishing rod mainly used for sweetfish fishing, and 1 is a proximal rod body in which a plurality of intermediate rod bodies 6 and tips (not shown) are provided so as to be swingable; As is clear from FIG. 1, this hand-side rod body 1 is formed into a hollow, gently conical shape, and an auxiliary rod with a diameter larger than that of the hand-side rod body 1 is provided on the outer periphery of this hand-side rod body 1. The body 2 is fitted into the mantle so that it can move forward and backward.
Further, as is clear from FIG. 1, this auxiliary rod body 2 is also formed into a hollow, gently conical shape.

and on the outer peripheral surface of the hand side rod body 1, and
First and second mating parts 11 and 12 are formed over a predetermined length at the front and rear parts of the length direction, respectively, and each mating part of the proximal rod body 1 is formed on the inner periphery of the tip of the auxiliary rod body 2. 11 and 12, and the third mating part 21 and the second mating part provided on the outer periphery of the rear end of the proximal rod body 1 are formed. 12 form a first fitting part 7 that fits into each other when the auxiliary rod body 2 advances rearward with respect to the proximal rod body 1, and the third mating part 21 of the auxiliary rod body 2, A first fitting part 11 provided on the front outer periphery of the proximal rod body 1 forms a second fitting part 8 that fits into each other when the auxiliary rod body 2 is retracted.

Further, as is clear from the embodiment shown in FIG. When the body 2 retreats and is held by the holding member 5, the proximal rod body 1 forms a non-shuttle part 13 exposed to the auxiliary rod body 2, and the rear end of the auxiliary rod body 2 and a butt ring 4 with a screw hole.
and a butt rubber 3b having an annular holding surface on the inner periphery,
A butt plug A consisting of a plug body 3 screwed into the screw hole of the butt ring 4 is attached to the annular holding surface of the butt rubber 3b of the butt plug A when the auxiliary rod body 2 is retracted.
A holding member 5 is provided which contacts the outer circumferential surface of the proximal end portion of the proximal rod body 1.

As is clear from FIG. 1, this holding member 5 is
It has a fitting length extending in the length direction of the rod bodies 1 and 2, and is provided with a fitting inner circumferential surface 5a into which the proximal outer circumferential surface of the proximal rod body 1 is fitted. The outer circumferential surface of the member 5 facing the fitting inner circumferential surface 5a is
It is supported on the base end of the auxiliary rod body 2 via the butt rubber 3b and the butt ring 4. Further, the holding member 5 is made of a flexible material such as synthetic resin. Note that the holding member 5
In addition to being made of synthetic resin, it may also be made of rubber.

Further, the first mating portion 11 is formed on the outer peripheral surface of a synthetic resin ring 14 provided on the outer periphery of the proximal rod body 1, as shown in FIG. 1, or is formed integrally with the proximal rod body 1. It is.

The auxiliary rod body 2 according to the present invention is used to adjust the overall length of the fishing rod, and the butt plug A is attached thereto in the same way as the proximal rod body of a general fishing rod. Therefore, no butt plug is attached to the proximal rod body 1 of the present invention.

In the fishing rod formed as described above, the auxiliary rod body 2 is fitted around the outer periphery of the hand side rod body 1 so that it can extend, so that the user can fish for sweetfish by holding this auxiliary rod body 2. . And the auxiliary rod body 2
As is clear from FIG.
is exposed to the auxiliary rod body 2, so when catching a caught sweetfish along with a decoy ayu, grasp the auxiliary rod body 2 and the non-mantle fitting part 13 of the hand side rod body 1,
The auxiliary rod body 2 can be easily advanced toward the hand side rod body 1.

When this auxiliary rod body 2 is advanced, the first fitting portion 7, that is, the third mating portion 21 provided on the auxiliary rod body 2, and the second The mating portions 12 fit into each other, and the auxiliary rod body 2 can be held in an extended state relative to the proximal rod body 1.

In addition, when shortening the overall length of the fishing rod, such as when changing a decoy sweetfish, it is possible to hold the hand-side rod body 1 and the auxiliary rod body 2 protruding from the hand-side rod body 1, and then move the auxiliary rod body. 2 was able to retreat instantly,
Because the overall length of the fishing rod can be shortened, in other words, the length of the fishing line relative to the fishing rod can be made longer.
This makes it easy to exchange decoy sweetfish.

Further, when the auxiliary rod body 2 is retreated with respect to the hand side rod body 1, the second fitting portion 8, that is, the third mating portion 21 provided on the auxiliary rod body 2, and the hand side rod body 1 are fitted into each other, and the second fitting part 12 of the proximal rod body 1 comes into contact with the fitting inner circumferential surface 5a of the holding member 5. Therefore, this holding member 5 and the second
The fitting portion 8 can effectively hold the retracted auxiliary rod body 2 to the proximal rod body 1.

In addition, since the fitting inner peripheral surface 5a of the holding member 5 has a fitting length extending in the length direction of the rod body, the fitting inner circumferential surface 5a of the holding member 5 has a fitting length extending in the length direction of the rod body, so that the fitting inner peripheral surface 5a of the holding member 5 has a fitting length extending in the length direction of the rod body. Not only can rattling be prevented, but the movement of the auxiliary rod body 2 in the advancing direction can be maintained. Therefore, simply by moving and holding the auxiliary rod body 2 with the holding member 5, the fitting length at the distal second fitting part 8 can be reduced. It can be made shorter, which means its holding power can be weakened. As a result, not only can the auxiliary rod body 2 be advanced quickly in the case of no load, but also the fitting of the second fitting portion 8 can be prevented even if the respective rod bodies are deformed under the load of the fishing rod. Since the length can be shortened, the degree of increase in the mating force will not be so large, and therefore,
Even if the fitting force of the second fitting part 8 on the tip side increases when a load is applied, the increase can be made smaller compared to the case where the holding member 5 is not provided on the base side. Even when a load is applied, the auxiliary rod body 2 can be advanced immediately, and the caught sweetfish can be taken in quickly, and the auxiliary rod body 2 can be advanced instantly.
At this time of advancement, the auxiliary rod body 2 can be advanced without vertically swinging the rod body on the tip side.
That's how much you can take in the ayu without cutting it.

Furthermore, since the holding member 5 is flexible and has the fitting inner circumferential surface 5a having a fitting length, the outer diameter of the proximal end can be adjusted by cutting the proximal rod body 1. Even if there is a dimensional error, the base end portion of the auxiliary rod body 2 can be held in the length direction with respect to the proximal rod body 1 without being affected by this dimensional error. Since the outer circumferential surface opposite to the fitting inner circumferential surface 5a is supported on the proximal end side of the auxiliary rod body 2, the second fitting part 8 is used as a fulcrum to support the proximal end side of the proximal rod body 1. The acting radial load can be carried on the proximal end side of the auxiliary rod body 2. Therefore, when a radial load acts on the proximal end side of the hand side rod body 1, the holding member 5 Since only one side in the radial direction is pressed against the carrier side and compressed, the amount of movement of the proximal rod body 1 in the radial direction due to the load is very small, and it does not move to the extent that it rattles. It is. As a result, even though the holding member 5 has flexibility, it is possible to prevent the holding member 5 from shaking against the auxiliary rod body 2 on the proximal end side of the proximal rod body 1, and even after repeated use. It is also possible to avoid damage to the member 5 due to the load in the radial direction and cracking of the proximal opening of the proximal rod body 1.

Furthermore, since the holding member 5 is attached to the butt plug A of the auxiliary rod body 2, even if there is a dimensional error in the inner diameter of the proximal end of the auxiliary rod body 2, it is possible to Even if there is a dimensional error in the inner diameter of the proximal end of the auxiliary rod body 2 due to an error in the cutting position when cutting the auxiliary rod body 2, the holding member 5 can be easily attached regardless of this dimensional error. , and can be installed reliably.

(Effects of the invention) As explained above, according to the invention, the fitting inner circumferential surface 5a of the holding member 5 has a fitting length extending in the length direction of the rod body, so that the auxiliary rod body that has retreated 2
Not only can the proximal rod body 1 on the proximal side be prevented from wobbling, but also the movement of the auxiliary rod body 2 in the advancing direction can be maintained. The length of the fitting at the fitting portion 8 can be shortened, that is, the holding force can be weakened.
As a result, not only can the auxiliary rod body 2 be advanced quickly when there is no load, but also the fitting of the second fitting portion 8 can be prevented even if the rod bodies are deformed when a load is applied to the fishing rod. Since the length can be shortened, the degree of increase in the fitting force is not so great. Therefore, even if the fitting force of the second fitting part 8 increases when a load is applied, the increase will not be so large. can be made smaller than when the holding member 5 is not provided on the base side, so even when a load is applied to the fishing rod, the auxiliary rod body 2 can be advanced immediately, and the faster the fishing rod is hooked, the sweetfish can be caught. In addition, since the auxiliary rod body 2 can be immediately advanced, the auxiliary rod body 2 can be advanced without causing the tip side rod body to swing in the vertical direction, and that is all. This allows you to take in sweetfish without letting them run out.

Further, the holding member 5 having the fitting inner circumferential surface 5a is
Since it is made of a flexible material, even if there is a dimensional error in the outer diameter of the proximal end due to cutting of the proximal rod body 1, the auxiliary rod body 2 will not be affected by this dimensional error. This makes it possible to maintain movement in the radial and longitudinal directions with respect to the proximal rod body 1.

Further, the holding member 5, which holds the proximal rod body 1 by the fitting inner circumferential surface, supports the outer circumferential surface facing the fitting inner circumferential surface 5a on the proximal end side of the auxiliary rod body 2. Therefore, the radial load acting on the proximal side of the proximal rod body 1 using the distal second fitting part 8 as a fulcrum can be borne on the proximal side of the auxiliary rod body 2. Although the holding member 5 has flexibility, the auxiliary rod body 2 on the proximal side of the proximal rod body 1
It is possible to prevent rattling against the
Even after repeated use, it is possible to avoid damage to the holding member 5 due to the load in the radial direction and cracking of the proximal opening of the proximal rod body 1.

In addition, since the holding member 5 is attached to the butt plug A on the proximal end side of the auxiliary rod body, even if there is a dimensional error in the inner diameter on the proximal side of the auxiliary rod body 2, that is, on both ends of the molded rod body. Due to an error in the cutting position when cutting the end to form the auxiliary rod body 2 of a predetermined length, the auxiliary rod body 2
Even if there is a dimensional error in the inner diameter on the proximal end side, the holding member 5 can be easily and
It can be installed reliably.
