[Problems to be solved by the device]

 However, in this structure, a notch for this through hole, that is, for introducing the fishing line is formed in the front rod pipe, and even when the front and rear rod pipes are spliced together, the circumference of the notch for introducing the fishing line is formed. The rod pipe body is only the wall of the rod pipe, and the notch makes the fishing rod very weak.

[0004] Accordingly, an object of the present invention is to improve the strength of a hollow fishing rod provided with a hole for introducing a fishing line. It is also intended to prevent the edge of the hole from being blunted or cracked or cracked during the processing of the hole or during fishing.

[0005]

[Means for Solving the Problems]

 In view of the above-mentioned object, the present invention provides a rod tube formed of a fiber-reinforced composite material with a hole for introducing fishing line from the outside to the inside, and integrally forming a peripheral portion including an edge portion of the hole into a thick wall. A middle fishing rod is provided. Further, the reinforcing fiber at the edge of the hole is provided with a woven cloth.

Since the peripheral portion including the edge of the fishing line introducing hole of the rod pipe is integrally thickened, it is possible to reinforce the reduction in strength of the rod pipe due to the provision of the hole. Further, if the reinforcing fibers at the edge of the hole are provided with a woven cloth, it is difficult to cause wrinkles during processing of the hole or during fishing, and cracks and cracks can be prevented.

[Embodiment of device]

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 3 shows an example of the form of a hollow fishing rod according to the present invention. The front rod tube 11 is joined to the rear rod tube 13, and a top guide 23 is attached to the tip of the front rod tube 11. A reel seat 17 for fixing the reel 15 is attached to the rear rod pipe 13, and a fishing line introducing portion 21 for introducing the fishing line 19 into the rod pipe 13 is provided in the front position thereof. There is. The fishing line 19 is drawn out from the reel 15, is inserted into each rod tube through the fishing line introducing portion 21, and is led out from the top guide 23 to the outside.

FIG. 1 is a longitudinal sectional view of the fishing line introducing portion of FIG. 3, and FIG. 2 is a transverse sectional view taken along the line BB of FIG. The rod tube 13 is formed with a narrow elongated hole 35 that is long in the axial direction of the rod tube, and a tubular guide 47 held by an outer frame cylinder 37 is inserted into this hole 35 in an inclined shape. Has been. Since the existence of the hole 35 significantly reduces the strength of the rod tube 13, as shown in the figure, the peripheral portion including the edge portion of the hole 35 is formed in the thick portion 25 and integrally formed with the rod tube main body portion. There is.

In this embodiment, as shown in FIG. 4, the thick wall portion 25 has an intermediate layer 29 having a wall thickness almost the same as that of the main body portion 27 of the rod tube 13 and having a diameter slightly larger than that of the main body portion 27. The inner layer 31 is integrally formed inside the intermediate layer 29, and the outer layer 33 is integrally formed outside the intermediate layer 29.

The intermediate layer 29 is formed by extending the main body portion 27 of the rod tube 13, and like the main body portion 27, for example, a high-strength fiber such as carbon fiber mainly composed of axial length direction fibers is reinforced. It is made of a composite material. The inner layer 31 is made of, for example, a composite material in which a woven fabric of reinforcing fibers made of glass fibers, organic fibers, or the like is used as a reinforcing material. The outer layer 33 is made of, for example, a composite material in which a woven fabric of high-strength fibers such as carbon fibers and glass fibers is used as a reinforcing material.

The outer frame 37 has substantially the same length as the entire length of the thick wall portion 25, and is fixed to the thick wall portion 25 with an adhesive. In this embodiment, the positioning projection 39 formed on the front end of the outer frame 37 is fitted into the positioning recess 41 of the thick wall 25. The outer frame 37 may be formed integrally with the thick wall portion 25. A guide hole 45 that is inclined from the rear end portion 43 toward the narrow elongated hole 35 is formed in the outer frame 37. The substantially linear tubular guide 47 is inserted and fixed in the guide hole 45. The rear end 49 of the tubular guide is located outside the rod tube 13, and the front end 51 is located inside the rod tube 13.

A jaw 53 is formed at the rear end of the tubular guide 47, and the jaw is inserted into a recess 55 formed at the end of the outer frame cylinder 37. The tubular guide 47 is bonded or press-fitted. And is fixed to the outer frame cylinder 37. An annular guide ring 57 made of a wear-resistant material such as silicon carbide, zirconia, or alumina is inserted and fixed in the recess 55. The front end portion 51 of the tubular guide 47 abuts on the tip of the narrow elongated hole 35 of the thick portion 25, and then protrudes inside the rod tube 13. Further, a chamfered flat surface or a chamfered curved surface is formed on the inner surface of the front end of the tubular guide 47.

The angle between the central axis of the tubular guide 47 and the central axis of the rod tube 13 is preferably 20 degrees or less, and more preferably 5 to 15 degrees. Moreover, the outer diameter of the tubular guide 47 is preferably 30% or less of the outer diameter of the thick portion 25. By doing so, the width of the narrow elongated hole 35 can be reduced, and the strength of the rod tube 13 can be reduced. It can prevent the deterioration.

In the hollow fishing rod configured as described above, the thin long hole 35 having a long diameter portion in the axial direction of the rod pipe 13 is formed in the thick portion 25 integrally formed with the rod pipe 13. At the same time, an outer frame cylinder 37 is attached to the outside of the thick portion 25, and a substantially straight line is formed in a guide hole 45 formed by being inclined from the rear end portion 43 of the outer frame cylinder toward the narrow elongated hole 35. Since the tubular guide 47 of the rod guide is inserted and fixed, the rear end portion 49 of the tubular guide is positioned outside the rod tube 13, and the front end portion 51 is positioned inside the rod tube 13, the fishing line introduction portion of the rod tube 13 The rigidity can be significantly improved as compared with the conventional one, and the sliding resistance of the fishing line at the fishing line introduction portion can be significantly reduced as compared with the conventional one.

That is, a thick portion 25 in which a narrow elongated hole 35 is formed is formed in a portion of the rod tube 13 excluding a joint portion, and an outer frame cylinder 37 is attached to the thick portion. Since the tubular guide 47 is inserted into the outer frame 37, the rigidity of the fishing line introducing portion 21 of the rod tube 13 can be significantly improved as compared with the conventional case. In particular, by reducing the outer diameter of the tubular guide 47, it is possible to reduce the width of the narrow elongated hole 35, and it is possible to prevent the rigidity of the fishing line introducing portion 21 from being greatly reduced.

Further, in the hollow fishing rod configured as described above, it is possible to easily reduce the angle formed by the tubular guide 47 and the rod tube 13, and the sliding resistance of the fishing line 19 in the fishing line introducing portion 21. Can be significantly reduced from the conventional one. In the above embodiment, the annular guide ring 57 is arranged at the rear end of the tubular guide 47, and the chamfered portion is provided at the front end, so that the sliding resistance of the fishing line 19 can be further reduced.

As shown in FIG. 3, the position of the reel seat 17 and the position of the fishing line introducing portion 21 are formed so as to be separated from each other by a predetermined distance. Since it can be easily formed at a predetermined distance from the surface, the fishing line introducing portion 21 does not interfere when gripping the reel sheet 17, and the fishing line 19 can be prevented from coming into contact with the hand.

Further, in the hollow fishing rod constructed as described above, since the thick portion 25 has the multi-layer structure using the woven cloth, it is possible to process the narrow elongated hole 35 or to use the fishing rod. It prevents the occurrence of cracks, and also prevents cracks, cracks, etc. from occurring even when a large stress is applied. In the above embodiment, the fishing line introducing portion 21 is formed in the rod rod 13 on the rear side, but the present invention is not limited to this example. For example, the fishing line introducing portion is formed in a rod pipe such as a middle rod. Of course, it's okay.
