Japanese Patent Laying-Open No. 2006-75018 (paragraph number [0024], FIG. 6) JP 2005-27593 A (paragraph number [0004], FIG. 6)

The fishing rod employs a configuration in which the hand side rod supports the tip side rod which is approximately 1.5 times the total length of the hand side rod in a cantilevered state. Therefore, a large load is applied to the heel tip of the hand side skeleton while the heel end of the tip side skeleton is fitted inside.
In spite of having to support such a large load, the heel tip of the proximal housing is only formed in a cylindrical body having a substantially constant thickness, and the strength may not be sufficient. there were.
Therefore, as shown in FIG. 6 of Patent Document 2, it is conceivable to arrange a reinforcing pattern (hereinafter referred to as a reamer pattern) to reinforce the wall thickness on the inner peripheral surface side of the heel tip portion of the proximal skeleton. .
However, even in such a configuration, the outer peripheral surface of the heel tip of the heel side skeleton is raised, or a step portion is formed on the main pattern wound around the reamer pattern. There have been problems such as generation of wrinkles and a decrease in strength due to meandering of reinforcing fibers.
On the other hand, in order to avoid the meandering of the fibers described above, it is also conceivable to wind a reamer pattern around the outer peripheral surface of the heel tip of the proximal housing as shown in FIG.
However, even in this case, a step is formed between the portion where the reamer pattern is wound and the outer peripheral surface of the main pattern located on the base side of the reamer pattern, and the appearance is deteriorated at this step portion. At the same time, in order to level the stepped portion, it is corrected with a resin paint, and further, a leveling process is applied by a centerless polishing machine.
An object of the present invention is to provide a fishing rod that suppresses a decrease in bending strength and the like, eliminates an uncomfortable feeling in appearance design, and is easy to manufacture.

〔Constitution〕
A feature of the invention according to claim 1 is that the proximal side casing is configured to have an inner layer disposed at the distal end of the collar, and an outer side disposed over the entire length of the proximal side casing outside the inner layer. The inner layer is formed by winding a fiber-reinforced prepreg reamer pattern around a small-diameter tip portion of a core metal, and bulges inward from an inner peripheral surface located on the heel side from the heel tip portion. The outer layer is formed on the base portion side of the small-diameter tip portion to a large-diameter portion that is larger than the outer diameter of the small-diameter tip portion and exhibits a constant or substantially constant outer diameter until reaching the base end. The main pattern made of fiber reinforced prepreg is wound, and the outer peripheral surface is configured to be a straight outer peripheral surface having a constant or substantially constant outer diameter, and the function and effect are as follows.

[Action]
The rod tip portion of the proximal rod body, by forming the inner layer that bulges inwardly from an inner peripheral surface located Saomoto side of the rod tip portion of the proximal rod body, hand source side rod body It was possible to increase the thickness of the heel tip without causing a step on the outer peripheral surface, and to secure a bending strength sufficient to connect and support the tip side skeleton.
On the other hand, the outer layer formed by winding the main pattern made of fiber reinforced prepreg can be formed on a straight outer peripheral surface having a constant or substantially constant outer diameter, and can suppress deterioration in appearance. In addition, as in the prior art, this is because the main pattern made of fiber reinforced prepreg that forms the outer layer is wound around the outer side of the inner layer, but the reinforcing fiber of the main pattern is also present due to the presence of the inner layer. Is not meandering.
As a result, the strength of the fiber is sufficiently exhibited.
Furthermore, since the outer peripheral surface of the outer layer is configured to have a constant outer diameter or a substantially constant outer diameter over the entire length, a processing step for leveling the step is not required or reduced even if necessary. Therefore, the mounting operation is facilitated even when the reel seat or the grip portion is externally mounted.

〔effect〕
As described above, by forming the inner layer that bulges inward and the outer layer in which the outer diameter of the outer peripheral surface is wound constant or substantially constant, a decrease in bending strength and the like is suppressed, and the appearance design is improved. It was possible to provide a fishing rod that was easy to manufacture and that was free from discomfort.

〔Constitution〕
According to a second aspect of the present invention, there is provided an inner inclined surface portion which reams the reamer pattern and expands the inner peripheral surface of the inner layer with a gradient of 1/1000 mm to 5/1000 mm on the tip side. Since the outer peripheral surface of the base end portion of the tip side housing is formed on the outer inclined surface along the inner inclined surface, the following effects are also obtained.

[Function and effect]
Since the inner inclined surface part and the outer inclined surface part are formed, when the both end parts are connected by fitting the end part of the tip side casing into the tip end part of the hand side casing, Since the front side is formed in a shape that expands in diameter at a slope of 1/1000 mm to 5/1000 mm, the following can be said.

That is, the outer inclined surface portion of the tip side rod body can be processed without variation in a fixed fitting length by inclining at the inclination described above with respect to the shaft axis, and repeatedly fitted during actual fishing. This also prevents the fitting from becoming loose or the fitting length from changing. It tip side rod body is such that fixed even when the bending load on both acted in a state of being connected to the proximal rod body is small, adhesion between the outer inclined surface portion and the inner inclined surface portion holding As a result, the tip side housing is difficult to be removed from the hand side housing.

〔Constitution〕
A characteristic configuration of the invention according to claim 3 is that the inner layer is formed by winding a reamer pattern in which polyester reinforcing fibers are knitted, and the function and effect thereof are as follows.

[Function and effect]
That is, since the prepreg knitted with reinforcing fibers is wound as a reamer pattern, it exhibits strength not only in bending strength but also in the shearing direction as compared with the case of using just-aligned prepreg.
Moreover, compared to the case of using an aligned prepreg that uses highly elastic reinforcing fibers such as carbon fibers, polyester reinforcing fibers are used, so when processing the inner inclined surface portion, processing is easy. It can also contribute to weight reduction.

〔Constitution〕
The characteristic configuration of the invention according to claim 4 is that the inner inclined surface portion of the inner layer is formed in a rough surface, and the function and effect thereof are as follows.

[Function and effect]
Thus, when a bending force is applied in a state where the tip side casing is connected to the proximal side casing, the connection state is difficult to be released due to the rough surface, and no bending force is applied. Then, it is easy to release the connected state.

〔Constitution〕

Forming a small-diameter tip having a length slightly longer than the length corresponding to the layer, and being constant on the base side of the small-diameter tip until the outer diameter of the small-diameter tip is larger than the outer diameter of the small-diameter tip. The large diameter portion having a substantially constant outer diameter is formed, and the operation and effect thereof are as follows.

[Function and effect]
By using such a mandrel, the outer layer having a constant or substantially constant outer diameter can be formed as in the outer layer described in claim 1.
That is, since the small-diameter tip is formed, the reamer pattern is wound around the small-diameter tip so that the outer diameter is the same as the outer diameter of the large-diameter portion.
When the main pattern is wound from above the reamer pattern, an outer layer having an outer diameter that is constant or substantially constant is formed.
Thereby, processing steps such as polishing can be omitted or suppressed for the outer peripheral surface of the outer layer.

  Next, manufacture of the hand side housing 1 will be described. As shown in FIGS. 3 and 4, a cored bar 4 is prepared. The core metal 4 is a rod-shaped body formed by applying metal plating or the like to a heat-resistant and corrosion-resistant nickel / molybdenum alloy, surface-hardened steel (S45C), or the like. A small-diameter tip portion 4A having a length L slightly longer than the length corresponding to the inner layer 1B from the tip toward the base portion and exhibiting a constant outer diameter is formed. A large-diameter portion 4B that is larger than the outer diameter d of the small-diameter tip portion 4A and has a substantially constant outer diameter D is formed on the base portion side of the small-diameter tip portion 4A.

The outer diameter D of the large-diameter portion 4B is formed to be substantially constant, and is suppressed to a taper degree of 0.17 / 1000 mm from the tip to the base end.
The outer diameter d of the small-diameter tip 4A is formed to ensure only the inward protruding amount of the inner layer 1B, and has a constant or substantially constant outer diameter over the entire length along the axial direction. .

A prepreg is wound around such a metal core 4 to manufacture the proximal housing 1. As shown in FIG. 3, a reamer pattern 5 shorter than the entire length of the cored bar 4 and a main pattern 6 having a length corresponding to the entire length are wound.

As shown in FIG. 4, the other side 6c facing the one side 6a of the first main pattern 6A in a superposed state is at a position where the width W3 enters from the one side 6b of the second main pattern 6B.
Accordingly, the interval c corresponds to the width of one ply when wound around the cored bar 4, and the width W3 corresponds to two plies. Therefore, the width W2 of the first main pattern 6A has a width corresponding to 3 plies.
On the other hand, the width W3 of the second main pattern 6B has a width corresponding to two plies, and the width W4 of the remaining portion has a width corresponding to three plies. It has a width of 5 plies.

The two main patterns 6A and 6B are formed as follows. A prepreg sheet as a fiber reinforced resin sheet is formed by aligning reinforced fibers such as carbon fibers in one direction and impregnating the aligned reinforced fiber group with a thermosetting resin (or thermoplastic resin) such as an epoxy resin. . The prepreg sheet is cut into a predetermined shape to form the main pattern 6.
As the reinforcing fiber constituting the prepreg, specifically, glass fiber, aramid fiber, alumina fiber, etc. can be used in addition to carbon fiber, and as the resin, in addition to epoxy resin, thermosetting such as phenol resin, polyester resin, etc. A thermoplastic resin such as a conductive resin or PV (E) can be used. Further, the prepreg may be configured by impregnating a woven material with a resin.

As shown in FIG. 3, the reamer pattern 5 is formed by impregnating a woven or non-woven fabric made of polyester fiber with a thermosetting resin such as a polyester resin to form a prepreg sheet and cutting it into a predetermined shape. Alternatively, an aligned prepreg of glass (carbon) fibers may be used.
The reamer pattern 5 has a width W1 corresponding to two plies, and the thickness t1 is smaller than the thickness t3 of the second main pattern 6B and larger than the thickness t2 of the first main pattern 6A.

As shown in FIGS. 3 and 4, the reamer pattern 5 formed as described above is wound so as to fit into the small-diameter tip portion 4 </ b> A of the cored bar 4. The winding amount of the reamer pattern 5 is 2 plies, and the reamer pattern 5 is wound so that the outer peripheral surface after winding is flush with the outer peripheral surface of the large-diameter portion 4B of the cored bar 4.
After winding the reamer pattern 5, as shown in FIG. 4, the first main pattern 6A and the second main pattern 6B that are integrally connected are wound around the core from the first main pattern 6A. Then, as shown in FIG. 5, the first main pattern 6A is wound for two plies, and the second main pattern 6B for one ply is wound. Further, the first main pattern 6A is wound by one ply on the second main pattern 6B, and the second main pattern 6B for four plies is wound. In this way, the outer layer 1C is formed as shown in FIG.
Furthermore, although not shown, in order to reinforce the strength of the front portion of the proximal housing 1, a front portion reinforcement pattern is wound around the outside of the second main pattern 6B. The tip portion reinforcing pattern may be provided with a mouth portion reinforcing with a glass fiber cloth PP on the outside.

  After winding the reamer pattern 5 and the main pattern 6, the molding tape is spirally wound over the entire length of the main pattern 6 and fired together with the cored bar 4. After firing, the molded tape is peeled off, both ends are cut and cut into a predetermined length, and finish processing is performed to form the ridge material 1A.

  As described above, the outer layer 1C is formed to have a constant or substantially constant outer diameter over the entire length in a state in which the main pattern 6 is wound. Therefore, a centerless polishing step for adjusting the outer peripheral surface of the outer layer 1C. May be suppressed and buffed.

As shown in FIG. 6, the inner inclined surface portion 1 </ b> F is formed on the inner peripheral surface of the heel end portion of the heel material 1 </ b> A with a reamer tool (not shown). That is, the inner peripheral surface of the inner layer 1 </ b> B is formed on the inner inclined surface portion 1 </ b> F whose diameter is increased by an inclination of 1/1000 mm toward the tip side. The degree of inclination of the inner inclined surface portion 1F may be between 0.5 / 1000 mm and 5/1000 mm.
