A fastening ring 11 made of stainless steel having a 1a is rotatably mounted on the outside, and the fastening ring 11 is slidable in the axial direction between the tapered flange 10a of the grip ring 10 and the annular flange 9. I have. A front grip 12 is externally mounted on the rod tip side of the grip ring 10.

Next, a description will be given of the handle portion 1 into which the fitting portion of the rod body 2 having the above-described configuration is fitted.

The handle portion 1 has a tubular body 13 formed by impregnating carbon fiber as a reinforcing fiber with a synthetic resin.
, And the insertion hole 3 is formed from the tubular body 13. A reinforcing pipe 14 made of stainless steel is externally fitted to the end of the tubular body 13 on the rod tip side. The reinforcing pipe 14 has a straight pipe 15 having a thinner wall thickness and a uniform diameter than the tubular body 13, and a straight pipe 15. And the straight pipe 1
And a connecting pipe 16 having a diameter larger than 5.

The reinforcing pipe 14 is, as shown in FIG.
Is fitted over substantially the entire length of the tubular body 13 into which the tubular portion 13 is fitted, and the tubular body 13 in the fitted region is reinforced. The connecting pipe 16 has a tapered portion 16
a, which has a widened shape which is widened toward the rod tip side as a whole, and is externally mounted on the tubular body 13 so as to protrude from the rod tip side end surface 13a of the tubular body 13 to the rod tip side for a predetermined length. Be done. As shown in FIG. 3, a female screw portion 18 that is screwed with the male screw portion 11a of the fastening ring 11 is formed on the inner peripheral surface of the rod tip side at the projecting portion 17 protruding from the tubular body 13 to the rod tip side. The rod end side (the rod end side end surface 13a of the tubular body 13)
Is formed with an annular inner projection 19. The rod-end-side end surface 19a of the inner projection 19 is a contact surface with which the rod-side end surface 9a of the annular flange 9 comes into contact when the rod body 2 is fitted.

The inner projection 19 is provided with the locking projection 8.
As in the case of the locking projection 8, the locking notch 20 serving as a locking portion with which the concave and convex engagement is performed penetrates the inner projection 19 in the axial direction.
A pair is formed so as to face 0 degrees. As described above, the locking notch 20 is provided near the opening so as to engage with the locking projection 8 near the opening of the fitting hole 3.

Further, as shown in FIG. 5, when the annular flange 9 is in contact with the inner projection 19 in the axial direction, a predetermined axial direction is formed between the rod end side end surface 13a of the tubular body 13 and the locking projection 8. The distance between the rod end side end surface 19a of the inner projection 19 and the rod end side end surface 13a of the tubular body 13 so that the gap 21 can be formed;
And the axial length of the locking projection 8 are set. still,
As shown in FIG. 1, the tubular body 13 is provided with a pipe-shaped reel sheet 22 and a detachable tail plug 23.
In the figure, the reel sheet 22 is omitted.

The fishing rod according to the present embodiment has the above configuration.
The rod body 2 can be mounted on the handle 1 by fitting the fitting portion of the rod body 2 into the rod tip side of the tubular body 13. The engaging projection 8 engages with the notch 20 so that the fitted rod body 2 is locked by the locking notch 20 and the handle portion 1 is locked.
Relative rotation with respect to. Then, at the same time when the locking projection 8 engages with the locking notch 20, the annular flange 9 abuts on the inner projection 19 in the axial direction, and the fitting of the rod body 2 is stopped.

Thereafter, the male screw portion 11a of the fastening ring 11
Is screwed into the connecting pipe 16, the rod-side end face 11 b of the fastening ring 11 presses the annular flange 9 in the axial direction toward the handle portion 1, and the fastening ring 11 is tightened. 9 is the inner projection 19 and the fastening ring 1
1, the rod body 2 is completely pressed and sandwiched in the axial direction, so that the rod body 2 is completely integrated with the handle part 1 so that the rod body 2 can be prevented from coming off from the handle part 1. Conversely, after use, the rod body 2 can be easily separated by loosening the fastening ring 11 and pulling out the rod body 2 from the handle portion 1.

As described above, the separated state and the integrated state can be easily used by using the fastening ring 11, but the fishing rod is compared with the conventional anti-rotation structure using a pin as follows. There are significant advantages.

That is, the tubular body 1 of the rod body 2 and the handle 1
3 is adapted to prevent the rotation of the rod body 2 by engaging the concave and convex in the radial direction, so that there is no need to separately attach a pin to the handle portion 1 as in the conventional case, and processing and assembly are conventionally performed. In addition to being easier than the conventional type, the rotation can be prevented more reliably than the conventional type in which the rod body 2 is engaged with the end face because it is engaged with the concave and convex in the radial direction. Thus, the strength of the handle portion 1 can be prevented from being reduced. In particular, since the engagement is performed in the vicinity of the opening of the insertion hole 3, the processing is further facilitated as compared with the case where the engagement is performed inside the insertion hole 3.

Further, by making the tubular body 13 made of carbon, the handle portion 1 can be reduced in weight, and in addition, a contact surface and a locking notch 20 are provided on the metal connecting pipe 16 to exert a particularly large force. Since the portion is made of metal, sufficient strength can be ensured. In particular, by using stainless steel, corrosion that is particularly likely to occur in sea fishing can be prevented. Fastening ring 11
The same is true for Furthermore, since the annular flange 9 is configured to abut against the inner projection 19 to stop the fitting, the rod body 2 does not directly contact the rod end side end surface 13a of the tubular body 13, so that the rod end side end surface 13 can be cracked. There is an advantage that breakage of the film can be prevented.

On the other hand, on the rod body 2 side, it is possible to make the insertion pipe 6 from a metal other than the synthetic resin as described above, but it is not necessary to be as strong as the handle portion 1 side. By using a synthetic resin, the weight can be reduced. However, when the insertion pipe 6 is formed from a synthetic resin in this way, as described above, in order to prevent dimensional irregularities caused by water absorption and the like, and to ensure necessary and sufficient strength and durability. It is preferable to use glass-containing PBT.

Further, the locking projections 8 are provided not on the solid body 4 but on the separate insertion pipe 6, so that the locking projections 8 are protruded from the outer peripheral surface of the solid body 4 directly. The processing can be simplified, and the annular flange 9 has the locking projection 8.
Is reinforced, so that breakage of the locking projection 8 can also be prevented. In particular, as described above, when a plurality of locking projections 8 are provided,
Connecting the plurality of locking projections 8 with the annular flange 9,
It is preferable from the viewpoint of securing the strength of the locking projection 8. In addition, since the locking projection 8 does not abut the handle portion 1 such as the tubular body 13 or the connecting pipe 16 in the axial direction, the annular flange 9 abuts in the axial direction. A large force does not act in the direction, so that it is possible to prevent the locking projection 8 from being deformed or damaged due to an impact at the time of contact or repeated insertion / removal of the rod body 2, and to reliably engage the concave / convex for a long period of time. be able to.

In the above-described embodiment, carbon fibers are used as the reinforcing fibers of the solid body 4 and the tubular body 13, but glass fibers can also be used.
Further, the rod body 2 may be formed in a cylindrical shape. That is, the fitting portion may be hollow. Further, a configuration in which the tubular body 13 is provided only on the rod tip side of the handle portion 1 can be adopted.

In addition, various design changes can be made within the range intended by the present invention. For example, a concave groove which is concave in the axial direction is formed on the rod-side end surface of the handle portion 1 (the opening edge of the fitting hole 3). It is also possible to form the concave groove as a locking portion, or to form the locking portion like a key groove.

[0026]

As described above, in the fishing rod of the present invention, the locking projection and the locking portion are formed on the outer peripheral surface of the rod body and the handle portion, respectively, as a structure for preventing the rotation of the rod body. Therefore, there is no need to separately attach a pin to the inside of the insertion hole as in the related art, and processing and assembly are easier than in the past, and rotation is not stopped at the end face of the rod body as in the past, Since the outer peripheral surface of the rod main body is directly locked by the locking portion of the handle portion, an effect is obtained that the rotation of the rod main body can be more reliably prevented.

In particular, by providing an annular flange on the rod tip side of the locking projection and integrating this annular flange with the locking projection, the locking projection is reinforced and damage to the locking projection can be prevented.
In particular, the effect is great when a plurality of locking projections are provided. Further, since the locking projection is not in contact with the abutment surface of the handle portion to stop the fitting, but in a configuration in which the annular flange is abutted, the locking projection may be deformed or damaged by an impact due to the contact. Therefore, uneven engagement can be reliably performed for a long period of time.

Further, an insertion portion made of a synthetic resin or a metal is externally mounted on a rod base formed by impregnating a synthetic resin into a reinforcing fiber such as carbon fiber to form a fitting portion of the rod body. However, when the locking projection and the annular flange are formed on the insertion pipe, the processing becomes extremely easy as compared with the case where the locking projection and the like are formed directly on the rod base.

In the case where the locking portion is provided near the opening of the fitting hole so that the locking projection and the locking portion engage with each other near the opening of the fitting hole, the back side of the fitting hole (the rod). The processing of the locking portion is further facilitated as compared with the case where it is provided on the base side).

In particular, by forming the fitting hole from a tubular body formed by impregnating a synthetic resin into a reinforcing fiber such as a carbon fiber, the handle portion can be reduced in weight, and the end of the tubular body can be made lighter. By forming the locking portion on the metal connecting pipe externally attached to the, the strength of the locking portion can be sufficiently secured, and
Since the dimensional change of the locking portion due to water absorption or the like is small, rattling at the time of engagement can be more reliably prevented. In addition, by providing the contact surface on the metal connecting pipe instead of using the rod end side end surface of the tubular body as a contact surface, damage to the rod end side end surface of the tubular body due to contact of the rod body can be prevented. It can be reliably prevented.
