Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a fishing rod.

[0002]

2. Description of the Related Art Conventionally, in order to manufacture a rod of this type, a prepreg obtained by impregnating a reinforcing fiber such as carbon fiber with a thermosetting resin such as phenol is wound around a mandrel to form a rod material. In addition, winding a molding tape such as polyester or polypropylene for molding on the outer peripheral surface of the rod material in a spiral shape and baking it, peel off the molding tape after baking, and finish the outer peripheral surface of the rod material with the molding tape removed It was processed and then painted after finishing. As this finishing process, generally, the spiral ridges attached to the surface of the rod material by the molding tape are removed to smooth the surface (even the unevenness) and at the same time paste the paste on the smooth surface. As shown in FIG. 8, in order to improve the surface roughness, a centerless polishing machine (including a belt sander polishing machine) 10 is used for polishing, and then coating is performed. Or, after roughening the surface by buffing to improve the adhesion with the paint,
The undercoating is applied, then the surface of the coated part is polished again, and then the final coating is applied. This finish is applied in several layers until the surface is smooth.

[0003]

When the above-mentioned finishing method is adopted, polishing is performed by a centerless polishing machine (including a belt sander polishing machine) 10, and FIGS.
As shown in 0, no reinforcement fibers 2 remained on the surface of the rod material 5 and only a few scattered fragments of the cut fibers 2 were found to scatter the reinforcement fibers 2. It is presumed that it is taken. Moreover, on the surface of the rod material 5, there were further seen a recessed processing mark 9 along the circumferential direction, which was probably due to sanding. Therefore, since the reinforcing fiber 2 is removed and cut from the surface of the rod material 5, the strength improving effect due to the presence of the reinforcing fiber 2 cannot be expected not only in the surface of the rod material 5 but also in the entire rod material. However, a decrease in mechanical strength such as bending strength was unavoidable. In addition, depending on the method of smoothing by buffing and painting, not by the method of sanding,
On the surface of No. 3, the smoothness was not sufficient, and there was room for improvement in smoothness itself due to the addition of streaks 9 by buffing. For this reason, the amount of coating had to be increased, and the weight of the rod was not reduced. An object of the present first invention is to provide a fishing rod that can have a higher rod strength than before by setting the surface state of the rod material after finishing processing to a state different from the conventional state.

[0004]

The characteristic constitution according to the first aspect of the present invention is that there is a portion where resin is exposed and a portion where reinforcing fiber is exposed on the surface of the rod material after finishing. The effect is as follows.

[0005]

As shown in FIG. 6, when the resin 2 is exposed, the fibers 2 are not completely lifted from the resin 3, but the lower half of the cross section is embedded in the resin and the upper half Since it can be considered that the reinforcing fiber 2 and the resin 3 are integrated, the integrated state of the reinforcing fiber 2 and the resin 3 is maintained. Thereby, the function of improving the strength of the resin 3 by mixing the reinforcing fibers 2 with the resin 3 is not largely impaired.

[0006]

As a result, since the finishing process can be performed without cutting the reinforcing fiber while maintaining the integrated state of the reinforcing fiber and the resin to a minimum, the strength of the rod is increased as compared with the conventional one. It is possible to improve the operability of the rod, such as being able to sufficiently cope with the impact force during the matching operation when the fish is caught by the needle, and to extend the life of the rod. The second object of the present invention is, in addition to the object of the first invention, to provide a fishing rod capable of favorably coating the surface of the rod material after finishing.

[0007]

The characteristic constitution according to the second aspect of the present invention is that, on the surface of the rod material after finishing, there are a portion exposed by the resin and a portion exposed by the reinforcing fiber, and
The reinforcing fibers partially maintain a continuous state in the orientation direction and form a coating layer on the outer surface of the rod material, and the function and effect thereof are as follows.

[0008]

In addition to the same operation as the first invention, the following operation is also provided. That is, since the reinforcing fiber maintains a partly continuous state in the orientation direction, it is not cut at each part of the entire length as in the conventional case, and in that respect, the function as the reinforcing fiber can be sufficiently exhibited. The strength of the rod is increased. Further, since the reinforcing fibers are also exposed on the surface of the rod material, buffing or the like for roughening the surface of the resin in order to improve the adhesiveness of the paint when only the resin is exposed. There is no need to do it, the reinforcing fiber has the function of roughening,
Improves paint adhesion.

[0009]

As a result, due to the close contact with the reinforcing fiber,
The peeling resistance of the paint itself can be further improved as compared with the case where the paint adheres only to the resin. The purpose of the third invention is to
In addition to the object of the second invention, it is another object of the present invention to provide a fishing rod which can reduce the amount of coating and achieve weight saving of the rod.

[0010]

The characteristic constitution according to the third aspect of the present invention resides in that the surface of the portion where the resin is exposed is a smooth surface having a small surface roughness. is there.

[0011]

In addition to the same function as the second aspect of the invention, since the surface of the resin is a smooth surface, it is not necessary to apply extra paint to eliminate the processing marks as in the conventional case.

[0012]

Therefore, it is sufficient to provide an amount sufficient to exert the decorative function as a paint and the protective function of the surface of the rod, which can contribute to the weight reduction of the rod. The purpose of the fourth invention is to
In addition to the object of the second aspect of the present invention, there is a point of providing a fishing rod which can be coated well.

[0013]

A feature of the present invention is that the surface of the reinforcing fiber is in a state of protruding from the surface of the portion where the resin is exposed. On the street.

[0014]

[Function] The surface of the resin is smooth, and the reinforcing fibers located between the resins and protruding from the surface of the resin have a very small diameter. It becomes a state in which small-diameter reinforcing fibers are regularly applied as ridges on the surface.

[0015]

Therefore, since the ridges formed by the reinforcing fibers serve as a medium for enhancing the adhesion between the resin and the paint, the buffing and polishing which are required to enhance the adhesion between the resin and the paint as in the conventional case. It does not require grooving such as sanding, and since the ridges made of reinforced fiber are thinner than those grooving with such relatively coarse abrasive grains,
Since each part of the surface of the rod material is uniform with the protrusions of the reinforcing fibers regularly arranged between the resin, it is easy to apply the coating and the coating is in a good condition. Present.

EXAMPLE As shown in FIG. 1, a method of forming a rod by using a mandrel 1 will be described step by step. As shown in FIG. 1, the carbon-based reinforcing fibers 2 are aligned in the circumferential direction and the epoxy-based thermosetting resin 3 is attached to the reinforcing fibers 2.
Mandrel 1 with prepreg 4 impregnated with
Wrap around. As shown in FIG. 1, the carbon-based reinforcing fiber 2 extends in the axial direction.
The prepreg 4 in which the epoxy thermosetting resin 3 is impregnated around the reinforcing fiber 2 is wound as a second layer. As shown in FIG. 1, a carbon-based reinforcing fiber 2 is further aligned in the circumferential direction, and a prepreg 4 obtained by impregnating the reinforcing fiber 2 with an epoxy thermosetting resin 3 is wound as a third layer. To form. As shown in FIG. 1, a carbon-based reinforcing fiber 2 is further aligned in the axial direction, and a prepreg 4 obtained by impregnating the reinforcing fiber 2 with an epoxy thermosetting resin 3 is wound as a fourth layer, and a rod material is used. 5 is formed. In order to wind each of the layers described above around the mandrel 1, the prepreg 4 is set on a surface plate, one end of the prepreg 4 is heat-treated, and the mandrel 1 is placed on the prepreg 4.
Is wound around the mandrel 1 to be molded. As shown in FIG. 2, a molding tape 6 made of polyester or the like is spirally wound around the outer peripheral surface of the third layer, and the rolled rod material 5 is put into a firing furnace 7 as shown in FIG. And fire it. After firing, as shown in FIG. 4, the forming tape 6 is peeled off, the rear rod material 5 is cut into a predetermined length, and the following finishing process is performed. As shown in FIG. 5, the rod material 5 is loaded into the layer of the abrasive material 8, the abrasive material 8 is made to flow by vibrating, and the abrasive material 8 is abraded by the relative movement of the abrasive material 8 and the rod material 5. Is done.

The abrasive 8 is granular and has a hardness higher than that of the thermosetting resin 3 of the prepreg 4, and the reinforcing fiber 2
The polishing material 8 having a lower hardness is used. As shown in FIG. 6, the surface state of the rod material 5 that has been finished in this way is such that the reinforcing fibers 2 are projected from between the resins 3. In this projecting state, the resin 3 does not project the entire cross section but a part of the cross section. Therefore, resin 3
The integrated state with the reinforcing fiber 2 is not impaired and the strength is sufficient. Moreover, the reinforcing fiber 2 maintains its aligned state (orientation) and is in a continuous state in which it is not cut over substantially the entire length of the rod material 5, and exhibits the reinforcing function as the reinforcing fiber 2. Here, the orientation direction means the fiber direction at the time of forming the prepreg,
In this embodiment, the reinforcing fibers 2 are arranged in the aligned state, but if the reinforcing fibers 2 are arranged in a vertical and horizontal sheet form, the state in which they are arranged in the vertical and horizontal directions is referred to as the oriented state. To Then, as shown in FIG. 7, the reinforcing fibers 2 are kept aligned and exposed on the surface of the rod material 5, and 5
Since only a part of the fibers having a diameter of micron to 8 microns are exposed, it is possible to form a rough surface in which very fine fibers are projected in an extremely uniform state. Since the fibers 2 are thin, it is impossible to engrave such fine protrusions by processing using a sander or the like. Therefore, if the surface of the rod material 5 on which such uniform and fine ridges are formed is coated as described later, it is possible to obtain a glossy and smooth coated surface which has never been seen in the past. After applying the finishing process described above, the rod material 5
The surface of is painted using a painting method such as ironing to form a painted surface.

[Other Examples] Other thermosetting resins can be used as the prepreg 4, and thermoplastic resins can be used if circumstances permit, and the reinforcing fiber 2 is made of glass other than carbon fiber. Fibers and boron fibers can be used. Although the prepreg 4 is wound in a plurality of layers, it may be a single layer, and the direction of the reinforcing fibers 2 is not limited to the one described above, and if at least the first layer 2 is set in the circumferential direction, The second layer 3 and the third layer 4 may be in either the circumferential direction or the axial direction. The prepreg 4 is not limited to one in which the reinforcing fibers 2 are aligned in one direction, but may be one in which the reinforcing fibers 2 are arranged in an orthogonal state. In the finishing process with the abrasive material 8, the abrasive material 8 is made to have fluidity by vibration, but the abrasive material 8 may be sprayed onto the surface of the rod material 5 for processing, and as a method of providing fluidity, Alternatively, a method other than vibration may be used. As a state where the rod is partially continuous in the orientation direction, it is not limited to one that maintains a continuous state over substantially the entire length of the rod axis, but it is partially half of the entire length of the rod even if it is cut at one or two places. The position may be one that maintains a continuous state. Further, a continuous state may be maintained in the intermediate portion excluding the joining portions with other rods formed at both ends of the rod. Furthermore, if the above-mentioned fourth layer is obtained by orienting the reinforcing fibers 2 in the circumferential direction, the individual reinforcing fibers 2 aligned in the circumferential direction may be maintained in a continuous state in the circumferential direction. Of course, in this case as well, it may be cut at any place in the circumferential direction. As the reinforcing fibers 2 aligned in the circumferential direction, there is a structure in which a prepreg tape is wound in a spiral shape. In this case, the reinforcing fibers 2 are reinforced over the entire length of the prepreg tape. Fiber 2
May be continuous. However, it may be cut at any position in the circumferential direction, and the reinforcing fiber 2 located at the width end of the tape may be cut.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
