Description

[Detailed description of the invention] [Industrial application field] In the present invention, a first intermediate rod material between a former rod and a head and a second intermediate rod material provided inside the first intermediate rod material are used. The stored state of retreating into the first intermediate rod material, the second intermediate rod material is withdrawn outward, and the large diameter portion of the original rod side end is attached to the tip end side end of the first intermediate rod material. The present invention relates to a swing rod configured to be extendable and contractable into an extended state in which it is engaged and frictionally held.

[Conventional technology]

Conventionally, in the swing rod having the above-described configuration, all the intermediate rod members between the former rod and the tip are configured to be able to hold the friction only in the extended state.

[Problems to be solved by the invention]

The above-mentioned conventional structure has a fishing use form in which all the intermediate rod materials are pulled out and the rod is extended to the longest state, and a transport storage form in which all the intermediate rod materials and ears are stored in the original rod to shorten the overall length. Although it is provided so as to be switchable, the above conventional structure has the following disadvantages.

In other words, in the fishing mode, since the total length of the rod is always constant, for example, when the fish is caught, the tip of the fishing line may be at a position away from the angler's hand, making it difficult to fish.

In addition, the condition of the rod when the fish is hooked is constant depending on the type of the rod, and it is necessary to appropriately change the condition to the first condition or the body condition according to the difference in the fishing conditions such as the type of fish and the difference in the fishing place. Was impossible, and there was a problem that multiple rods had to be prepared.

The purpose of the present invention is to eliminate the above-mentioned disadvantages.

[Means for solving the problem]

The characteristic configuration of the present invention is that in the drawing rod described at the beginning, the large diameter which can be fixed to the second intermediate rod material by the frictional engagement with the tip end side of the first intermediate rod material in the housed state. A bulging portion is provided, and the thickness of the large-diameter bulging portion is formed so as to be in a thin state toward the tip of the rod, and in the storage state, between the large-diameter portion and the large-diameter bulging portion. , The first
An air gap is formed between the inner peripheral surface of the intermediate rod material and the outer peripheral surface of the second intermediate rod material, and the operation and effect are as follows.

[Action]

In the extended state in which the large-diameter portion is engaged with the tip end of the first intermediate rod material, the entire length of the rod is long, and the rod has a single cylindrical structure over the entire length of the rod, so that it can be easily bent. The fishing by the condition is enabled.

In the stored state in which the large-diameter bulging portion is engaged with the tip end of the first intermediate rod material, the overall length of the rod is reduced, and the first intermediate rod material and the second intermediate rod material are In the overlapping part of the above, a double cylinder structure is formed to increase the bending rigidity,
It becomes easier to bend only on the tip side than the intermediate rod material, and fishing by the first condition is possible.

At this time, since a gap is formed between the first intermediate rod member and the second intermediate rod member, and the large-diameter portion and the large-diameter bulging portion are held by frictional engagement, It is possible to prevent the rigidity from becoming extremely high as compared with those provided in close contact, and to allow bending,
The first tone can be obtained to the extent that the bending of the entire rod is not hindered.

Further, the large-diameter bulging portion is formed in the pressure portion so as to be easily frictionally engaged, but the thickness is gradually reduced toward the tip of the rod. Even when the projection is in frictional engagement with the mating side, the rigidity at this portion is not increased and the stress concentration is reduced.

[Effect of the invention] Therefore, it is possible to change and adjust the total length of the rod according to the difference in the fishing situation, and it is also possible to change the condition such as tip condition and body condition without increasing rigidity and stress concentration etc. As a result, practical convenience was improved.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 shows the swing rod according to the present invention. This draw rod is configured by sequentially inserting a plurality of intermediate rod members (3) between a former rod (1) and a tip (2). That is, the former rod (1), the tip (2), and each of the intermediate rods (3) are each formed in a gently tapered cylindrical body, and the former rod (1)
The intermediate rod material (3) having a smaller diameter than the large diameter side opening of the intermediate rod material (3) and the ear tip (2) are sequentially inserted and the base end of the original rod (1) is butt plug (5). It is closed by. Then, the inner diameter of the original rod (1) is formed to be slightly smaller than the inner diameter of the intermediate rod material (3) on the inner diameter side of the inner rod material (3). The rod (3) and the large-diameter portion of the tip (2) prevent the pull-out to the outside, and are configured to maintain the rod in the extended use state by frictionally holding the rod. By retracting and storing the ear tip (2) in the original rod (1), it is configured such that the entire length convenient for transportation can be set to a short storage state.

Then, as shown in FIGS. 1 (a) and 3, the large diameter of the end of the second intermediate rod material (3b) on the side of the original rod (1), which is provided inside the first intermediate rod material (3a) on the way. Part (6) is the first intermediate rod material (3
The second intermediate rod material (3b) is arranged closer to the tip (2) side in the longitudinal direction while being engaged with the end of the tip (2) of (a) to be frictionally held and set in an extended state. A large-diameter bulging portion (7) as a large-diameter bulging portion is formed at the portion, and the large-diameter bulging portion (3b) is accommodated inside the first intermediate rod material (3a). The bulge (7) is the first intermediate rod (3a)
It is configured to be able to fix the relative position by frictional engagement with the end of the tip (2). Further, in a state where the second intermediate rod material (3b) is housed in the first intermediate rod material (3a), the large-diameter portion (6) of the second intermediate rod material (3b) engages and engages. A substantially cylindrical engagement sleeve (8) for holding friction is attached to the first intermediate rod material (3).
It is attached to the inner side of a). The large-diameter bulging portion (7) has a medium-high pressure state at the intermediate position, and has a small diameter so as to become thinner toward the front of the medium position. This can reduce stress concentration.

Then, in a state where the second intermediate rod material (3b) is in the storage position, between the large-diameter portion (6) and the large-diameter bulging portion (7) of the second intermediate rod material (3b), A gap (S) is formed between the inner peripheral surface of the first intermediate rod member (3a) and the outer peripheral surface of the second intermediate rod member (3b).

With this configuration, by setting the second intermediate rod member (3b) in the extended state, it is possible to set a trunk condition that bends over a long range when a fish catches (second example). By changing the second intermediate rod material (3b) to the stowed state, the rigidity is increased in this overlapped part, and it is set to a bend that bends only at the tip side part. (See FIG. 2 (b)). In addition, the structure that holds friction, and by forming the gap (S), can be set in a pre-adjusted state even in the housed state while allowing bending and preventing breakage by dispersion of stress. (See FIG. 1 (b)).
In particular, damage can be prevented when an excessive load is applied due to a sudden fish pull or the like.

(Another embodiment)

The large-diameter bulging portion (7) may be formed on all the intermediate rod materials of the intermediate rod (3).

Further, a threading guide may be provided on the outer peripheral surface on the small diameter side of each intermediate rod material.

In the present invention, it is also possible to use an intermediate rod material having a different tone.
