Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod body, and more particularly, to a rod body for a hollow rod in which a fishing line can be inserted.

[0002]

2. Description of the Related Art A hollow fishing rod has a fishing line passage through which a fishing line is inserted. Further, in the rod body, an introduction port for introducing a fishing line is formed on the front side of the reel mounting portion, and an opening for introducing and extracting the fishing line is formed at the tip of the tip. In such a hollow rod, the fishing line sent from the reel is introduced into the fishing line passage inside the rod body from the introduction port, passes through the fishing line passage, and is guided to the outside from the opening at the tip of the tip.

[0003]

In such a fishing rod, it is necessary to reduce the contact area between the fishing line and the inner surface of the rod in order to reduce the resistance when the fishing line is introduced and led out. For this reason, the rod diameter at the tip portion becomes relatively large. Here, the tip portion of the fishing rod is required to be soft, that is, have relatively low rigidity and be tenacious. Therefore, a hollow rod that has no choice but to have a thick tip is manufactured using a material having a low elastic modulus (for example, a prepreg made of carbon fiber having a tensile elastic modulus of about 19 tons). However, there is a limit to softening the tip of the tip, and there is a problem that the tip becomes too stiff when maintaining a predetermined strength. If the tip is hard, it will be difficult to catch the delicate part of the fish with the tip.

Further, in the hollow rod, since the fishing line repeatedly passes through the fishing line passage on the inner surface and comes into contact with the inner surface with a strong force at this time, it must be sufficiently resistant to abrasion due to rubbing or the like. An object of the present invention is to provide
It is to adjust the condition of the tips. Another object of the present invention is to reduce the sliding resistance of the fishing line and reduce wear.

[0005]

The rod body according to the first aspect of the present invention is a rod rod for a hollow rod through which a fishing line can be inserted, and has an innermost layer and a first outer layer. The innermost layer is formed of a prepreg of a carbon fiber base material, and a fishing line can be inserted through the inner peripheral portion of the prepreg. The first outer layer is formed of a prepreg of a nonwoven fabric base material, and is arranged on the outer peripheral side of the innermost layer.

In this case, since the innermost layer that comes into contact with the fishing line is formed of the prepreg of the carbon fiber base material, the sliding resistance of the fishing line is small and the wear is small. Further, since the outer layer is formed by using the prepreg of the non-woven fabric base material, it is possible to suppress the rigidity and soften the tip of the tip. A rod body according to a second aspect of the present invention is the rod body according to the first aspect of the present invention, further including a second outer layer formed of a prepreg of a glass fiber base material and disposed on the outer peripheral side of the innermost layer. In this case, the strength can be maintained by the prepreg of the glass fiber base material, and the rigidity can be suppressed by inclining the fiber orientation with respect to the axial direction.

A rod body according to a third aspect is the rod body according to the second aspect, wherein the second outer layer is disposed on the outermost peripheral side. Since the second outer layer is a prepreg made of a glass fiber base material, it has less moisture infiltration than when the prepreg made of a non-woven fabric base material is arranged in the outermost layer. Also, it has high strength and is not easily scratched. A rod body according to a fourth aspect of the present invention is the rod body according to the second or third aspect, wherein the first outer layer and the second outer layer are alternately arranged.

A rod body according to a fifth aspect of the present invention is the rod body according to any one of the second to fourth aspects, wherein the second outer layer is arranged such that the orientation of the fibers is inclined with respect to the axial direction of the rod. Therefore, the rigidity can be lowered and the tone of the tip can be softened even if the glass fiber base material prepreg is used. A rod body according to a sixth aspect of the present invention is the rod body according to any one of the first to fifth aspects, wherein the rod body is used as a tip rod of the middle-range rod. In this case, the tone of the tip can be set to an appropriate softness even in the middle-pile rod.

BEST MODE FOR CARRYING OUT THE INVENTION A centering rod 1 shown in FIG. 1 is a swing-out rod and has a base rod 2 having a grip portion G, an intermediate rod 3 connected to a tip side of the source rod 2, and an intermediate rod 3. And a tip rod 4 connected to the tip side of the. As shown in FIG. 2, each rod body of the base rod 2, the intermediate rod 3, and the tip rod 4 has a tubular shape, and a fishing line passage 5 through which a fishing line can be inserted is formed inside.

A reel 11 around which the fishing line 10 is wound is mounted near the grip portion G of the base rod 2. Original pole 2,
Each of the intermediate rod 3 and the tip rod 4 has a gentle conical shape, and an inlet 12 for the fishing line 10 is formed at the tip portion of the base rod 2. In addition, a tubular fishing line guide 1 is provided at the tip of the tip rod 4.
3 is attached. The fishing line 10 drawn out from the reel 11 enters the inside of the base rod 2, the intermediate rod 3 and the tip rod 4 from the introduction port 12, and is drawn out from the fishing line guide portion 13 to the outside.

As shown in the enlarged view of FIG.
First prepreg layer 20 of carbon fiber base material as innermost layer
And two kinds of second to sixth prepreg layers 21 and 22 arranged on the outer periphery of the carbon fiber base material prepreg layer 20. The carbon fibers of the first prepreg layer 20 are oriented in the circumferential direction. Of the second to sixth prepreg layers, the second, fourth and sixth prepreg layers 21 (21
a, 21b, 21c) is a prepreg layer of a glass fiber base material, and the orientation of the glass fibers is 30 with respect to the axis of this rod.
。It is inclined. Further, the glass fiber base material prepreg layer 2
The third and fifth prepreg layers 22 (22a, 22b) arranged so as to be sandwiched by 1 are prepreg layers based on a nonwoven fabric.

In the tip rod 4 having such a structure, since the carbon fiber base material prepreg layer 20 is arranged in the innermost layer,
This innermost layer has a relatively high hardness, and the sliding resistance when the fishing line slides on the surface is small. Further, there is little damage due to sliding of the fishing line. Further, since the outer layer is formed by using the non-woven fabric base prepreg layer 22 and the glass fiber base prepreg layer 21 in which the fiber orientation is inclined with respect to the axis, the outer layer has a lower rigidity as compared with the conventional rod material. Yes, the rod becomes softer. Moreover, a stick stick with a strong stickiness can be obtained.

The glass fiber base material prepreg layer 21c
Since it is placed in the outermost layer, compared with the case where the non-woven fabric base material prepreg layer 22 is placed in the outermost layer, the penetration of water and the like is suppressed, and the strength is high, so that the surface is not scratched. It can be prevented. Next, a method for manufacturing the tip rod 4 will be briefly described. First, a release agent made of wax or the like is applied to the outer periphery of the mandrel, and then the carbon fiber base material prepreg 20 is wound around the outer periphery of the mandrel at a predetermined pitch. In addition, the five outer prepreg layers 21 and 22 are
It is formed by tightly winding a prepreg tape made by impregnating glass fiber with a resin and a prepreg tape made by impregnating a non-woven fabric with resin.

Since the innermost prepreg layer 20 is wound by using a prepreg tape in which carbon fibers are oriented in the length direction of the tape, the orientation of the carbon fibers as a rod is in the circumferential direction of the mandrel. It will be in line. Also,
The second, fourth and sixth prepreg layers 21a, 21b, 2
For 1c, since the prepreg tape in which the glass fibers are inclined and oriented in the tape width direction is used, each of these layers is in a state in which the glass fibers are oriented and inclined in the axial direction.

After arranging the prepreg layers in this manner, polyethylene terephthalate (PET) is formed around the prepreg layers.
A shape-retaining tape (not shown) made of polypropylene, polypropylene, or the like is wound and fired by a conventional method. After firing, the shape-retaining tape on the outer periphery is peeled off, and the release tape on the inner periphery is removed, whereby the tip rod 4 is obtained. [Other Embodiments] (a) The present invention can be similarly applied to a parallel connecting rod in addition to the illustrated drawing rod. Fig. 4 shows the details of the splicing type tip rod.

Briefly describing the tip rod 25 of this example, a top holder 26 is provided at the tip of the tip rod 25, and a guide ring 27 for guiding a fishing line is provided on the inner surface of the tip of the top holder 26 of the lake. Is fixed.
A guide ring 28 for guiding the fishing line is also provided in the axially intermediate portion of the fishing line passage. By these guide rings 27 and 28, the area where the fishing line contacts the inner surface of the rod is reduced, and the sliding resistance is reduced. The yarn 29 is wound on a part of the outer peripheral surface of the tip rod 25 over a predetermined range.

(B) The present invention can be applied not only to the tip rod 4 but also to other rod bodies.

[0018]

As described above, according to the present invention, it is possible to soften the tone of a hollow fishing rod even if the tip rod is thickened. In addition, in the fishing line passage of the hollow fishing rod, the sliding resistance of the fishing line can be reduced and the wear can be reduced.

When the prepreg layer of the glass fiber base material is arranged as the outermost layer, water is less soaked in and scratches are less likely to occur.
