Description

[Detailed description of the invention] (Related industrial field) The present invention relates to the structure of a fishing rod. More specifically, it relates to the structure of a fishing rod that uses multiple parts connected together.

(Prior Art) Figure 4 shows an ordinary two-piece fishing rod. The fishing rod 1 consists of a tip rod 1a and a base rod 1b, which are joined at a tip joint portion 2 of the base rod 1b. 2a is the tip rod 1a
This is the joining part.

The fishing rod 3 shown in FIG. 5 has a joint part having a mating part 5 inserted between the tip rod 1a and the base rod 1b, so that it can be extended longer than the rod shown in FIG. 4 by this amount.

Now, how to join such a joining rod is shown in FIGS. 6 to 8. The joining method shown in Figure 6 is so-called "parallel joining"
Then, as shown in Figure 6b, connect the mating part 2a of the tip rod 1a to the base rod 1.
It is designed to be inserted into the end joint part 2 of b. The mating part 2a has a cylindrical shape, and the relationship between the outer diameter A on the rod tip side of the mating part, the outer diameter B on the base side, and the inner diameter C of the tip joint part 2 of the original rod 1b is AB, and it is cylindrical. Or it tapers and becomes thicker towards the tip of the rod.

Also, A>C, and the tip rod 1a is the base rod 1b.
, and are adapted to fit together at the mating portion 2a between AB.

FIG. 7 is a "swing out" joint, which connects mutually tapered sections. That is, the main rod 1
If the tip side inner diameter A of b, the tip side outer diameter B of the mating part 2a of the tip rod 1a, and the base side outer diameter are C, AB, that is, it has a cylindrical or tapered shape.

B<C, that is, it is tapered.

With this configuration, it is convenient to handle because it is only necessary to pull the tip rod 1a. However, it has the disadvantage that it cannot produce thinner rods than the above-mentioned parallel joints.

FIG. 8 shows a "spigot" joint, which has a joining part 2a with a tapered diameter on the tip rod 1a side, which is inserted into the joining part 2 of the base rod 1b for joining. In this case, the mating portion 2a is A in FIG.
B, ie, cylindrical or tapered toward the base. Similarly, the mating part on the main rod side is CD, that is, cylindrical or tapered.

In the case of this "pilot" joint, the thinnest rod can be designed, but it is disadvantageous in terms of cost compared to the above two joint methods.

The above three joints are the basic ones. Also,
There is no rule as to which joint is the top or bottom of the rod, but the thicker end is generally the bottom when swinging out.

(Problems to be Solved by the Invention) The present invention provides a fishing rod in which the length of the rod can be extended by a connecting part 4 as shown in FIG. This is what I am trying to do. Furthermore, in order to facilitate the extension operation, it is provided immediately following the grip portion so that the extension operation can be performed smoothly.

(Means for solving the problem) In a fishing rod consisting of a tip rod, a base rod, and a grip,
A swing-out mating part is provided at the base of the main rod, a parallel joint part is provided at a predetermined distance from the swing-out joint part, and correspondingly, a cylindrical part for the parallel joint is provided at the tip of the grip part. Further, a tapered part for swinging and joining is provided adjacent to the inside of the cylindrical part, and the length can be easily adjusted by these swinging and joining parts and the parallel seaming part.

(Embodiment of the invention) FIG. 1 shows a fishing rod according to the invention. It is composed of a tip rod 1a, a base rod 1b, and a grip part 1c. An extension portion corresponding to part 4 of FIG. 5 in a known fishing rod is integrally provided within the rod.

FIG. 2 shows the connection structure between the base rod 1b and the grip portion 1c. As shown in Fig. 2a, the main rod 1b has a swinging joint part (see Fig. 7) 6 at its base, and a parallel joint part (see Fig. 6) 7 at a certain distance from this swinging matching part 6. have.

The grip part 1c corresponds to the above-mentioned structure of the main rod 1b.
is provided with a tapered part 6' for swinging and joining at its tip and a cylindrical part 7' for parallel joining adjacent to the tip of this tapered part 6'.

FIG. 2b shows a state in which the swinging part 6 of the base rod 1b and the tapered part 6' of the grip part 1c are engaged, that is,
The rod is shown in an extended state.

FIG. 2c shows a state in which the rod is retracted from the state shown in FIG. 2b, and the joint portion 7 of the base rod 1b is engaged with the cylindrical portion 7' of the grip portion 1c.

In addition, in order to set the base rod 1b in the grip part 1c with the above configuration, either divide the base rod 1b between the swinging part 6 and the joint part 7 into two, or divide the grip part 1c into two. Furthermore, the parallel joint portion 7 may be processed later.

FIG. 3 shows another example of the parallel joint portion in FIG. 2. In this case, the parallel joint part 8 is not considered as a joint part, but as a kind of rattling prevention, and a part 8 for the joint joint is fixed to the base of the grip part 1c, and the base rod 1 is fixed to the base of the grip part 1c.
The ends of b may be joined in parallel.

In the above explanation, the fishing rod is the tip rod 1a and the base rod 1.
Although the two-jointed rod (b) has been illustrated, the present invention is of course applicable to the case where there are three or more jointed rods, that is, when the tip rod consists of 1b to 1n.

(Effects of the invention) As described above, in the present invention, since the extension mechanism is provided integrally with the rod between the base rod and the grip, it is extremely easy to extend and retract.

Furthermore, as shown by curve B in Fig. 9, according to the conventional splicing method, the spliced portion C bends as shown in the figure.
Although this part is weakened, in the method of the present invention, as shown by curve A in Fig. 9, a load P is applied to the tip of the tip rod.
Even if it is stiff, the joint part C' (it is lower than the joint part C in the conventional type because it is close to the grip)
is straight, and there is no problem in terms of strength even if a large load P is applied.
