Description

  The present invention relates to a fishing rod housing having a reinforcing structure in the outermost layer of the head of the rod and a method for manufacturing the same.

  As the above-mentioned reinforcing structure, the prepreg in which the glass fibers are arranged in the state of intersecting the outermost layer of the mouth and the intersected glass fibers are impregnated with the synthetic resin is arranged along the shaft axis from the tip of the head of the head portion. There was one that was limited to a short length (see Patent Document 1).

Noto 2577431 gazette (Lines 34 to 38 of the fifth column of the gazette)

In order to arrange a reinforcing pattern made of a cross-shaped prepreg on the outermost layer of the above-described head portion, as shown in FIG. 6, the reinforcing pattern 3 is arranged on the outer peripheral surface of the main pattern 4 to be described later. .
As a result, a step corresponding to the thickness of the reinforcing pattern 3 is formed between the butt end of the reinforcing pattern 3 superimposed on the outer peripheral surface of the main pattern 4 and the outer peripheral surface of the main pattern 4. Moreover, since the reinforcing pattern 3 is made of knitted glass fibers as reinforcing fibers, the thickness is inevitably thick, and the step cannot be ignored. In addition, since the reinforcing fibers are knitted, the arrangement state of the reinforcing fibers tends to be uneven on the cut end face, and the end face of the reinforcing pattern 3 is difficult to be clarified.
In the process of manufacturing the housing, after winding the main pattern on the mandrel and before firing, in order to maintain the shape retention of the shell material wound with the main pattern, a forming tape is spiraled around the surface of the shell material. It is supposed to be wound around.
On the other hand, the heel end of the reinforcing pattern is cut in a state along the circumferential direction of the heel.
Therefore, when the molding tape reaches the butt end of the reinforcing pattern, it cannot be wound with the posture aligned, the spiral pitch is disturbed, or the amount of folding between adjacent molding tapes is not uniform. There is. As a result, problems such as uneven butt end positions of the reinforcing pattern to be positioned are likely to occur.
Therefore, as a means for solving this, the shape of the butt end of the reinforcing pattern is devised, and the width along the circumferential direction of the heel gradually increases toward the butt end side so as to follow the spiral winding state of the molding tape. The extension part (refer 3A of FIG. 3) of the narrow width shape which becomes short is formed.
However, even in this case, it is necessary to hide this part with a resin paint or the like because the extension part appears to impair the aesthetic sense as the butt end of the reinforcing pattern. A process is required, and the work load increases.
Since the reinforcing pattern itself is configured so that the reinforcing fibers intersect, the resin paint is absorbed in the portion surrounded by the reinforcing fibers intersecting, and the enclosed portion can be sufficiently covered with the paint. However, there is room for improvement in this aspect because holes are likely to be formed.

  An object of the present invention is to provide a fishing rod housing that can easily make the heel end of the reinforcement pattern more clearly stand out compared to the prior art and can suppress a step in providing the reinforcement pattern. .

〔Constitution〕
The characteristic configuration of the invention according to claim 1 is that the outermost layer has a reinforcing pattern made of a cross prepreg arranged in a state of intersecting the reinforcing fibers, and the axial direction length is longer than the reinforcing pattern, and the reinforcing fibers And a main pattern made of an alignment prepreg that is aligned in one direction, with the reinforcing pattern positioned at the head portion and the main pattern positioned on the buttock side of the reinforcing pattern. In addition, the heel end side end portion of the reinforcing pattern is formed in an extended portion where the width along the circumferential direction of the heel decreases toward the heel end side, and the heel side end portion of the main pattern is formed on the reinforcement pattern. The function and effect are as follows, being overlaid on the outer peripheral surface of the extended portion.

[Action]
In order to satisfactorily finish the butt end of the reinforcing pattern, the shape of the butt end side of the reinforcing pattern is formed in an extended portion in which the width along the circumferential direction of the heel decreases toward the butt end side. By superimposing the heel end portion of the main pattern on the outer peripheral surface of the extended portion, the heel end of the reinforcing pattern can be covered with the main pattern.
On the other hand, the tip side end portion of the main pattern is exposed, and a step corresponding to the thickness of the main pattern is formed. However, since the main pattern itself is the one in which reinforcing fibers are aligned, the thickness of the prepreg However, it can be made thinner than a reinforcing pattern in which reinforcing fibers are crossed. Thereby, the step at the heel end of the main pattern can be reduced as compared with the conventional configuration.
In addition, since the reinforcing fibers are aligned, the reinforcing fibers on the cut end surfaces are not likely to be uneven, and the end surfaces can be clearly positioned more easily than the reinforcing pattern. In addition, since the level difference can be reduced, even when the molding tape is wound, pitch disturbance, wrinkles, and the like are reduced as compared with the prior art, and the shape of the main pattern wrinkle tip can be easily adjusted.
On the other hand, the step formed by the butt end of the reinforcing pattern arranged inside the main pattern has an extension portion as described in the section of the conventional configuration, so that the molded tape is wound around The occurrence of inconveniences, such as leaning, is less likely to occur. In addition, since the extended portion is covered with the main pattern, it is not necessary to perform a process such as covering with a resin paint, which has been conventionally required, and the manufacturing burden is reduced.

〔effect〕
As described above, by changing the superposition of the reinforcing pattern and the main pattern, it is possible to easily determine the end of the main pattern on the surface and make it difficult to form a step. It became easy to manufacture.

  The characteristic configuration of the invention according to claim 2 is the guzzle portion on the outer peripheral surface of the heel material formed by winding an inner main pattern made of a prepreg in which a reinforcing fiber is impregnated with a resin around the mandrel in the invention according to claim 1 In addition, the reinforcing pattern is wound, and on the heel end side of the reinforcing pattern, the length in the heel axis direction is longer than that of the reinforcing pattern, and the reinforced fiber is aligned along the heel axis direction. The outer main pattern is wound to form the outermost layer, and the tip side end of the outer main pattern is wound over the outer peripheral surface of the extension portion of the reinforcing pattern, and the forming tape is wound on the outermost layer. After the firing, the molding tape is peeled off, and after the firing, it is cut to a predetermined length and then subjected to a polishing treatment, and the effects thereof are as follows.

[Function and effect]
That is, the rod material is fired in a state where the molding tape is wound, and after the firing, the molding tape is peeled off, cut into a predetermined length, and subjected to a polishing treatment to constitute a casing.
When applying this molding tape, the thickness of the outer main pattern is not as thick as the reinforcing pattern, so a step corresponding to the thickness of the heel end of the outer main pattern is formed, but the outer main pattern is a reinforcing fiber. Since the step is smaller than that of the reinforcing pattern, the winding pitch and the like are less disturbed, and the occurrence of wrinkles at the front end of the outer main pattern can be suppressed.
To form the outermost layer with the reinforcing pattern and the outer main pattern, after applying the reinforcing pattern to the head portion of the inner main pattern in advance, the tip side end of the outer main pattern is formed with the narrow shape of the reinforcing pattern. A first method of winding in a state of being overlapped on the outer peripheral surface of the butt end side or a second method of winding the integrated main pattern on the inner main pattern after the outer main pattern is previously superimposed on the reinforcing pattern The method can be adopted. As a result, the first method can be adopted when it is desired to wind the reinforcing pattern and the outer main pattern without any deviation, and when the relative positional relationship between the reinforcing pattern and the outer main pattern is positioned as set. Can adopt the second method.
Therefore, two kinds of production methods can be selected, and a degree of freedom in production can be secured.

  The body used for mountain stream dredging will be explained. As shown in FIG. 1, the outer peripheral surface of the butt end side end portion 1 </ b> A of the small diameter casing 1 is pressed against the inner peripheral surface of the tip end side end portion 2 </ b> A of the large diameter casing 2. The structure which maintains a drawer state is taken. In this case, since an applied force acts on the tip side end portion 2A of the large diameter casing 2, an outward opening force acts on the tip side end portion 2A of the large diameter casing 2.

  A reinforcing pattern 3 is wound around the outer peripheral surface of the heel side end portion 2A of the large-diameter frame 2 for the purpose of countering this outward opening force. As shown in FIG. 3, the reinforcing pattern 3 uses glass fibers g instead of carbon fibers c having high rigidity for the purpose of enhancing flexibility, and weaves the glass fibers g so that the glass fibers g cross each other. A prepreg sheet is formed by impregnating a fiber group with a thermosetting resin such as epoxy, and the prepreg sheet is cut into a predetermined shape.

As shown in FIG. 3, the reinforcing pattern 3 has a short length along the axial direction and is applied only to the head portion, and the shape of the buttock side end is positioned on the buttock side. The part a is formed in the extended part 3A in which one side a is formed on a hypotenuse close to the other side b and the width L in the circumferential direction is gradually reduced. Therefore, the reinforcing pattern 3 has a trapezoidal shape as a whole.
The reinforcing pattern 3 can have a thickness of 0.2 mm to 0.3 mm, and is preferably set to 0.25 mm.

A method for manufacturing the large-diameter housing 2 including the reinforcing pattern 3 having the above-described configuration will be described. First, the main pattern 4 will be described. As shown in FIG. 2, the main pattern 4 is a sheet-like prepreg formed by aligning reinforcing fibers such as carbon fibers c in one direction and impregnating the aligned reinforcing fiber group with a thermosetting resin such as epoxy. It is longer than the reinforcing pattern 3 in the axial direction, and is cut by a length corresponding to the entire length of the large-diameter housing 2.
As the reinforcing fiber, boron fiber or the like can be used in addition to the carbon fiber c. As the thermosetting resin, phenol or the like can be used, and in some cases, a thermoplastic resin can be used. The thickness of the main pattern 4 can be 0.13 mm to 0.15 mm.

Four main patterns 4 are prepared. That is, as shown in FIG. 2, the first main pattern 4 </ b> A composed of prepregs in which the carbon fibers c are aligned and arranged along the circumferential direction of the ridges is disposed in the first layer. In the second layer, a second main pattern 4B composed of a prepreg in which the carbon fibers c are aligned and aligned along the axial direction of the ridges is disposed. In the third layer, a third main pattern 4C composed of a prepreg in which the carbon fibers c are aligned and arranged along the circumferential direction of the ridges is disposed.
The main patterns 4A, 4B, and 4C from the first layer to the third layer are collectively referred to as an inner main pattern.

  As a method of forming the bag material 5 by winding the three main patterns 4A to 4C described above around the mandrel 6, the first main pattern 4A to the third main pattern in order from the first main pattern 4A at a time. There are two methods of winding the mandrel 6 at a time in a state where up to 4C is overlapped to form the bag material 5.

  As shown in FIG. 3, the reinforcing pattern 3 is wound around the heel-side end portion of the heel material 5 with respect to the heel material 5 formed by winding the main pattern 4 </ b> A or the like by adopting one of the methods described above. . In a state where the reinforcing pattern 3 is wound, the fourth main pattern 4D is wound around the buttock side of the reinforcing pattern 3.

As shown in FIGS. 3 and 4, the fourth main pattern 4D corresponds to the length in the axial direction of the reinforcing pattern 3 from the length along the axial direction of the inner main pattern 4A or the like in the fourth main pattern 4D. The heel side end 4d of the fourth main pattern 4D is wound in a state of being superimposed on the extended portion 3A of the narrow butt end of the reinforcing pattern 3 having a length.
Thus, although the method of winding the reinforcement pattern 3 and the 4th main pattern 4D in order may be taken, the tip side edge part 4d of the 4th main pattern 4D is previously made into the narrow shape of the reinforcement pattern 3. Alternatively, a method may be adopted in which the overlapped portion 3A is wound on the extended portion 3A of the buttock side end portion and the overlapped portions are wound simultaneously.

  As described above, the tip end 4d of the fourth main pattern 4D as the outer main pattern in which the carbon fibers c as the reinforcing fibers are aligned in a state along the saddle axis direction is an extended portion of the reinforcing pattern 3 Since it is applied in a state of being superimposed on 3A, a step is formed between the outer peripheral surface of the heel tip side of the fourth main pattern 4D and the surface of the reinforcing pattern 3.

However, since the thickness of the fourth main pattern 4D is thinner than that of the reinforcing pattern 3, the level difference formed at the heel end of the fourth main pattern 4D is not as large as that of the reinforcing pattern 3.
In addition, since the fourth main pattern 4D is formed by aligning the carbon fibers c, the end face of the heel tip is less likely to be disturbed as much as the reinforcing pattern.

As shown in FIG. 5, the bag material 5 with the outermost layer applied as described above is fired in a state in which a molding tape 7 such as polyester is spirally wound, and the molding tape 7 is peeled off after firing. Then, the large-diameter casing 2 is formed by cutting into a predetermined length and polishing.
When this molding tape 7 is applied, the thickness of the fourth main pattern 4D is not as thick as the reinforcing pattern, so there is little disturbance such as the winding pitch of the molding tape 7, and at the edge of the fourth main pattern 4D. Occurrence of wrinkles and the like can be suppressed. Further, since the extended portion 3A of the reinforcing pattern 3 is formed so as to gradually reduce the width in the circumferential direction of the heel, the heel side end portion 3A of the reinforcing pattern 3 overlaps with the fourth main pattern 4D. Then, when the molding tape 7 is wound, the occurrence of wrinkles and the like is good.

[Another embodiment]
(1) As the shape of the extended portion 3A of the reinforcing pattern 3, a shape in which the hypotenuse as the side a is formed in a straight line is shown. However, the side a may have an arc shape, It is not limited to things.
(2) As a configuration of the main pattern 4, if it is desired to reduce the weight of the casing A, it may be configured by the first main pattern 4 </ b> A and the fourth main pattern 4 </ b> D. The number of times of winding around the mandrel 6 is not limited to one ply but may be a plurality of plies.
