[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod.

[0002]

2. Description of the Related Art From the viewpoints of improving the slipperiness of a fishing line and preventing frictional damage on the inner peripheral surface of a rod tube, it is particularly necessary to press-fit or glue a fishing line guide into a formed rod tube and fix it after forming the rod tube. Japanese Unexamined Patent Publication No. 56-127032 discloses a through fishing rod in which a single fiber fishing line guide ring is integrally formed on the inner peripheral surface of a rod pipe.

[0003]

However, in the former publication in which the rod is fixed after the rod tube is formed, the fishing line guide is removed or displaced during fishing by bending or deformation of the fishing rod. Also, in the latter publication, the fishing line guide annular body has a circular cross-sectional shape, and the height is about the same as the width dimension,
The inner peripheral surface of the fishing line guide annular body is regulated by the outer peripheral surface of the mandrel at the time of forming the rod tube, and when the fiber reinforced prepreg is wound from the outside, the fiber line reinforced prepreg has a fishing line guide annular body portion having an outward convex shape. Become. For this reason, when heated and baked, the fibers meander and the strength of the rod tube decreases.

Accordingly, an object of the present invention is to provide a through fishing rod in which a fishing line guide is firmly fixed to the inner peripheral surface of a rod pipe, and the fixing prevents a reduction in strength of the rod pipe.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention provides a fishing line guide having a width larger than a thickness on an inner peripheral surface of a rod pipe formed by winding a prepreg obtained by impregnating or mixing resin with high-strength fiber. The outer peripheral side of the rod is integrally fixed in an embedded manner , the inner peripheral side protrudes from the inner peripheral surface of the rod pipe, and the outer side of the rod pipe of the fishing line guide fixing portion wider than the thickness is the fishing line guide.
A through fishing rod characterized by being gently swelled substantially along the outer periphery of the fishing rod.

[0006]

[Action] fishing line guide, with the inner peripheral side is to be the projecting state, since the integrally fixing the outer peripheral side to the embedded form on the inner circumferential surface of the rod tube, it is possible to reduce the fishing line resistance have be firmly fixed However, since this fishing line guide is wider than its thickness, the rod tube at the fishing line guide site swells gently so as not to protrude suddenly, and the fibers meander in a suddenly deformed shape during firing, reducing the rod tube strength. Can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 shows a first embodiment of a through fishing rod according to the present invention. High-strength fiber such as carbon is impregnated with a thermosetting resin such as epoxy resin, or a fiber-reinforced prepreg (used in a broad sense including thermoplastic resin) mixed with thermoplastic resin such as polyamide is wound and fired. An annular fishing line guide 12 of ceramics or the like is provided on the inner periphery of the formed rod tube 10.

The fishing line guide 12 has a width B which is larger than a thickness, and has a wide flat cross section.
The dimension B is about several millimeters or more. The outer periphery of the fishing line guide 12 is integrated with the inner peripheral surface 10S of the rod tube 10 so as to be embedded. However, in this embodiment, the buffer layer 14 is interposed between the inner peripheral surface 10S of the rod tube 10 and the fishing line guide 12. The fishing line guide 12 has its outer peripheral side facing the buffer layer 1.
4 is buried in the inner peripheral surface 10S of the rod pipe, with the inner peripheral surface 12S protruding from the inner peripheral surface 10S of the rod pipe.

As described above, since the fishing line guide 12 is embedded in the inner peripheral surface 10S of the rod tube 10 and is integrally fixed at the time of heating and firing, the fixing portion 10B of the fishing line guide 12 of the rod tube 10 bulges outward. . However, since the fishing line guide 12 is wide and has a flat cross-sectional shape, the bulging portion 10B bulges wide and smoothly with respect to the other flat main body 10A.

As a result, the fiber of the bulging portion 10B does not meander much, the strength of the rod 10 is maintained, and the inner peripheral surface 12S of the wide flat fishing line guide 12 protrudes inside. It is possible to provide a high-strength fishing rod that smoothly guides the fishing line. However, the thickness of the bulging portion 10B is
It is preferable to form the layer slightly thicker than 0A to prevent the strength from being reduced. Also, the inner peripheral surface 1 of the fishing line guide 12
Since 2S has a wide flat shape, the fishing line can be smoothly guided without being damaged as compared with a small circular case.

The fishing line guide 12 can be made of a material other than the ceramics, such as a metal, a resin-based fiber reinforced material, or a metal-based fiber reinforced material. Also, the buffer layer 1
4 is a rubber having a lower elastic constant (softer) than the rod 10;
A fiber reinforced prepreg, a synthetic resin, a resin tape (or a sheet), or the like is used. Since the buffer layer 14 exists, the bulging portion 10B can bulge more smoothly, and the influence of the fishing line guide 12 on the bending deformation of the fishing rod is reduced.

Next, a method of manufacturing the fishing rod shown in FIG. 1 will be described. As shown in FIG. 2 , a receiving member layer 22 made of an elastic member such as a silicon tube or a clay-like member is interposed on a mandrel 20, and an annular fishing line guide 12 having an inner diameter for fastening the receiving member layer 22 to some extent is provided outside the receiving member layer 22. insert.

Thereafter, a resin tape or the like for the buffer layer 14 is wound so as to cover each fishing line guide 12, and a fiber-reinforced prepreg is wound thereon, and the outer periphery is tightened with a tightening tape or the like. By heating and firing, the rod tube 10 and each annular fishing line guide 12 are integrated. After cooling, the fastening tape and the mandrel 20 are removed, and finally the receiving member layer 22 is removed.

As described above, since the receiving member layer 22 was present at the time of molding, the inner peripheral side of each annular fishing line guide 12 buried therein protrudes from the rod pipe inner peripheral surface 10S. Further, since the fixing portion of each fishing line guide 12 is not pressed from the outside with an excessive force, the rod tube at that portion swells outward smoothly, and as a result, the meandering of the fiber is small, and the rod tube strength is reduced. Can be held.

[0015]

As is apparent from the above description, according to the present invention, since the outer peripheral side of the fishing line guide is integrally fixed when the rod tube is fired, the fixing is strong, and the inner peripheral side of the fishing line guide is the inner peripheral surface of the rod tube. As the fishing line guide is wider than its thickness, the outside of the rod tube at the fixed part gently swells, and the rod line's strength is reduced because it does not suddenly protrude. It is possible to provide a fishing rod that can prevent fish from flowing through.
