Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow fishing rod having a trunk soft tone.

[0002]

2. Description of the Related Art A hollow fishing rod having a fishing line inserted therein is used for the purpose of preventing entanglement of the line. For example, Japanese Unexamined Patent Publication No. 7-59491 discloses a large fishing rod in which a fishing line introducing portion is formed at a predetermined position of a splicing rod such as a middle rod spliced to a splicing portion of a front end of a base rod.

[0003]

However, since the fishing line is drawn into the fishing line introducing section from the reel located at the rear position, the rod tube region behind the fishing line introducing section largely bends and the fishing line is bent. This is inconvenient because it comes into contact with the surface, which increases the line resistance and damages the fishing line. Therefore, it is usual that the bending rigidity is set to be large behind the fishing line introducing portion. In addition, since the fishing line introducing portion is provided with a through hole for passing the fishing line from the outside to the inside, the rod tube is insufficient in strength as it is, so the rod tube is thickened and reinforced. Therefore, it has a high bending rigidity, and the operation parts such as the joint and the grip behind it,
It is also necessary to form the reel leg fixing portion and the like with high bending rigidity. That is, the fishing line introducing portion and the area behind the fishing line introducing portion have high bending rigidity and are difficult to bend.

Therefore, in the center fishing rod of the above-mentioned publication, the total length region of the rear portion of the fishing line introducing portion of the joint rod and the entire base rod does not bend so much, and the distance from the load position of the fish to the hand becomes long, and the load is increased. On the other hand, a large bending moment always acts on the hand, which makes it difficult to operate the fishing rod, and it can be said that the fishing rod is easily tired. Although this cannot be used as a fishing rod for large fish, it is unsuitable for fishing rods with small torso that target small fish and medium-sized fish.

Accordingly, it is an object of the present invention to make a hollow fishing rod suitable for a fishing rod with a soft trunk. Another object of the present invention is to easily detect in advance that the fishing rod of the soft trunk has a large deflection, and further to provide a hollow fishing rod suitable for the fishing rod of the soft trunk.

[0006]

SUMMARY OF THE INVENTION In view of the above object, the present invention according to claim 1 is such that the rod tube at the rear portion of the fishing rod has a small diameter portion and a large diameter portion having a larger outer diameter behind the small diameter portion. And a fishing line introducing section for introducing the fishing line into the rod tube from the outside in the large-diameter portion, a reel leg fixing section and an operating section for the fishing rod are formed behind the fishing line introducing section, and the fishing line introducing section is rearward from the fishing line introducing section. Is provided with a bending rigidity higher than that of the small diameter portion.

According to a second aspect of the present invention, the rod pipe at the rear portion of the fishing rod has a small diameter portion and a large diameter portion having a larger outer diameter behind the small diameter portion, and the fishing line is externally attached to the large diameter portion. A fishing line introducing section to be introduced into the pipe is provided, and an operating section of the fishing rod is formed behind the fishing line introducing section and on the front side of the reel leg fixing section, and the rear side from the fishing line introducing section is further compared with the small diameter section. (EN) Provided is a hollow fishing rod, which has a high bending rigidity and a bending rigidity of the operating portion is lower than a bending rigidity behind the reel leg fixing portion.

According to the first aspect of the present invention, the fishing line introducing portion is provided in the large diameter portion in the rear portion of the fishing rod, and the reel leg fixing portion and the operating portion are formed behind the fishing line introducing portion to have high bending rigidity, and the small diameter portion in front of the fishing rod introducing portion is formed. Is formed to have a much lower flexural rigidity than the high flexural rigidity part, so that sufficient bending occurs from the small diameter part at the rear part of the fishing rod, so that a middle fishing rod suitable as a trunk softening element can be provided.

According to a second aspect of the present invention, when the load from the small diameter portion is such that the front side largely bends and the rear portion does not substantially bend from the reel leg fixing portion, the bending rigidity of the operating portion is from the reel leg fixing portion to the rear side. Since it is formed to be low, it can be flexed to some extent, the flexural deformation is transmitted to the hand holding the operating portion, and it becomes easy to recognize the limit of breakage of the rod that largely flexes.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in more detail based on the embodiments shown in the accompanying drawings. FIG. 1 shows a joint-type medium-through fishing rod made of fiber-reinforced synthetic resin, in which a base rod 10, a middle rod 12, and a tip rod 14 are spliced side by side.
The tip of the original rod 10 is a splicing part TB1, and here the middle rod 1
The rear end portion 2 is spliced together, and the tip rod 14 is spliced at the joint portion TB2 at the front end portion of the middle rod 12. A top guide 16 is attached to the tip of the tip rod. Behind the joint portion TB1 is the rear portion of the fishing rod, and a small diameter portion 10A (or the same diameter may be used) that is smaller in diameter than the outer diameter of the joint portion is formed. 10
B, and the fishing line introducing portion 22 is provided in the large diameter portion 10C following this.
Is provided, and a reel leg fixing portion 10E to which a reel leg fixing device 18 for fixing the leg of the reel 20 is attached is formed in the rear thereof.

The front and rear of the reel leg fixing portion are fishing rod operating portions, and a gripping portion 10D held between the fishing line introducing portion 22 and the reel leg fixing portion 10E is held by the front hand, and the reel leg fixing portion 1 is provided.
Behind 0E is the operation area 10F for the fishing rod operated by the rear hand.
It is. Reference numeral 26 is a rod end part, which is removable. As described above, the rod tube has a large diameter from the fishing line introducing portion 22 to the rod butt, and its bending rigidity is higher than that of the small diameter portion 10A in the front portion thereof, and as will be described later at the load level of the target fish. In addition, the grip portion 10D hardly bends when the small diameter portion 10A largely bends, except that the grip portion 10D slightly bends. However, the small diameter portion 10A can be flexed sufficiently, and this fishing rod is
Is a fishing rod with a soft trunk that can be bent from the front region of the fishing rod and can be bent from the rear part of the fishing rod. Partly each joint T
B1 and TB2 have high bending rigidity because the front small-diameter rod tubes are spliced together, and have a small deflection, but since the length is short, they do not significantly affect the deflection characteristics of the entire fishing rod.

In the base rod 10 of this example, the joint portion TB1 has a length of 15 cm, the small diameter portion 10A has a length of 40 cm, and the sharp taper portion 1 has a length of 10 cm.
It is about 70 cm from 0B to the tail. The respective length ratios of the main rod, the middle rod, and the tip rod are as shown in the figure, and are substantially the same.
It is preferable that the length of the small-diameter portion is about three times or more the length of the joining portion TB1 in order to improve the flexibility from the front of the sharp taper portion 10B. In addition, since the fishing line introducing portion is arranged at the substantially central portion of the base rod 10 in this manner, there is no region of high bending rigidity other than the joint portion after the front portion thereof, so that the fishing rod can be easily bent. Become.

The height H (see FIG. 2) of the fishing line introducing hole 22A of the fishing line introducing portion 22 is set higher than the surface of the rod pipe of the large diameter portion 10C. This is the reel 20 in the rear near
This is to prevent the fishing line 24 drawn in from coming into contact with the grip portion 10D or the hand holding the grip portion 10D. Further, since the fishing line introducing portion 22 is formed to have a length as illustrated, the fishing line introducing angle becomes large, but since the fishing rod has a torso shape, it bends like a two-dot chain line 30 when fish is caught. Such bending is preferable because the large introduction angle of the fishing line 24 and the inclination angle of the bending of the rod come close to each other, and the line resistance when winding the tensioned fishing line on the reel decreases.

A plurality of so-called cartridge type fishing line guides are inserted and arranged in the inside rod 12, and the fishing line guides can be washed by easily taking out each of them from the rear end of the inside rod 12. Also, the cartridge can be replaced with a new one. Furthermore, a spiral fishing line guide is integrally formed on the inner surface of the tip rod 14 to reduce the insertion resistance of the fishing line.

FIG. 2 is an enlarged view of the rear portion of the base rod 10. The large diameter portion 10C is formed with a long hole 10H in the front-rear direction into which the fishing line introducing pipe 22P provided with a fishing line guide made of ceramics at the front and rear ends is inserted in an inclined shape, and in order to compensate for the lack of strength due to the existence of this hole. , The rod tube in this area is thickened. Further, since the holding member 22S such as a synthetic resin holding the pipe 22P is fixed thereon, the strength is further improved. However, instead of the pipe held by the holding member, a fishing line introducing portion using a fishing line guide ring made of ceramics or the like which is arranged so as to cover the periphery of the hole 10H may be used.

A reel leg fixing portion 10E is provided slightly rearward of the fishing line introducing portion 22, and a grip between the reel leg fixing portion and the fishing line introducing portion is formed in a tapered shape in a forward tapered shape. The portion 10D has an average thickness smaller than that of the large diameter portion 10C, and in this embodiment, as shown in the figure, it starts from the rod pipe thickness of the large diameter portion and gradually decreases toward the rear. In the vicinity of the reel leg fixing portion 10E, the wall thickness is increased again, and the rear portion from the reel leg fixing portion 10E is formed to have the highest bending rigidity. The thick portion of the large-diameter portion 10C may be extended so as to partially enter the grip portion 10D.

Even when the small-diameter portion 10A largely bends, the rear portion of the reel leg fixing portion 10E hardly bends, but the gripping portion 10D can bend to some extent. The bending can be sensed, the limit of the large bending of the small diameter portion 10A can be recognized, and the fishing rod can be used with care so as not to damage it. In order to make the bending rigidity of the grip portion 10D smaller than the rear region from the reel leg fixing portion 10E (obviously, the bending rigidity is much higher than that of the small diameter portion 10A), in addition to adjusting the wall thickness of the rod tube, strengthening to be used The fibers may be changed to change the elastic modulus, or the amount of circumferential reinforcing fibers may be adjusted. In this way, the strength against crush fracture is maintained and the bending rigidity is reduced for a large diameter. In the wall thickness adjustment, not only the gradual decrease as shown, but also the gripping portion 10D is made thin as a whole,
The average wall thickness may be thinner than the wall thickness of the large diameter portion 10C.

When the small diameter portion 10A is subjected to a large bending load, the gripping portion 10D can be bent to some extent, but under normal load, there is almost no bending and there is no hindrance to the operation of the fishing rod.
On the outside of the rod tube of the grip portion 10D, a grip cylinder member 10DC of cork or foam synthetic resin is fitted and adhered,
The grip feeling is improved. Since the grip portion 10D is formed in a tapered shape, the grip cylinder member 10DC can be inserted from the rod tip side and firmly fixed and bonded. Further, the grip cylinder member 10DC can be inserted from the tip of the rod even if the rear portion of the grip portion 10D is formed to have a large diameter.

The taper of the rod tube outer surface 10DS of the grip portion 10D is set to be larger than 3/1000. Furthermore, (15/10
A taper of about 00) ± (10/1000) is preferable.
The splicing method of the hollow fishing rod according to the present invention may be a reverse parallel splicing method, a spigot method, a swaying method, or the like. Alternatively, one rod may be used.

[0020]

As is apparent from the above description, according to claim 1 of the present invention, the fishing line introducing portion is provided in the large diameter portion in the rear portion of the fishing rod, and the reel leg fixing portion and the operating portion are formed behind the fishing line introducing portion. Since it is formed with high bending rigidity, and the small diameter part in front of it is formed with lower bending rigidity than this high bending rigidity part, sufficient bending occurs from the small diameter part at the rear part of this fishing rod. It is possible to provide a hollow fishing rod suitable as a soft tone of the trunk. Further, according to claim 2, when the load is so large that the front side is largely bent from the small diameter part and the rear part is hardly bent from the reel leg fixing part, the bending rigidity of the operating part is rearward from the reel leg fixing part. Since it is formed to be lower than the above, it can be somewhat bent, and the bending deformation is transmitted to the hand holding the operating portion, and it becomes easy to recognize the breakage limit of the rod that largely bends.
