Description

Technical Field

[0001] The present invention relates to a fishing rod characterized by a joint structure (assembly structure) between adjacent large-diameter rod sections and small-diameter rod sections.

Background Art

[0002] Generally, a fishing rod having a plurality of rod sections is configured such that adjacent rod sections are joined by a joint structure. As the joint structure, a butt joint type, a reverse butt joint type, an inlay type, and an outcast type are known. By joining them, the overall length of the fishing rod can be increased, and by releasing the joined state, the storage dimension of the fishing rod can be shortened. Normally, as disclosed in Patent Documents 1 and 2, for example, a tapered portion is formed at the joint portion between the large-diameter rod section and the small-diameter rod section. When the rod sections are inserted into each other in the axial direction, the rod sections are fitted together by the joint of the tapered portions.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the joint structure disclosed in Patent Document 1 described above, a tapered portion is formed on the outer peripheral surface of the small-diameter rod section, and a straight portion and a tapered portion are formed on the inner peripheral surface of the large-diameter rod section. The two are fitted together by combining the straight portion and the tapered portion. Such a joint structure has a problem that rattling is likely to occur because a gap is formed between the joint positions. In addition, since the taper fitting (sliding) between the small-diameter rod section and the large-diameter rod section is long, there is a problem that it becomes difficult to insert and remove due to sticking.

[0005] The integrated structure disclosed in Patent Document 2 described above forms straight portions and tapered portions alternately along the circumferential direction on the inner peripheral surface of the large-diameter rod, and fits a small-diameter rod having a reverse tapered portion formed on the outer peripheral surface to such an inner peripheral surface. Also in such a fitting structure, since the two are fitted together by combining the straight portion and the tapered portion, there is a problem that the taper alignment of the small-diameter rod and the large-diameter rod is long, and it becomes difficult to insert and remove them due to the sticking phenomenon.

[0006] Furthermore, in the integrated structure as described above, when axial looseness occurs in the fitted state, the fitting force becomes weak, and there is a problem that it easily comes off.

[0007] The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a fishing rod having an integrated structure in which the large-diameter rod and the small-diameter rod can be easily integrated, the fitting force can be improved, rattling is less likely to occur, and sticking is difficult.

Means for Solving the Problems

[0008] In order to achieve the above object, a fishing rod according to the present invention has an integrated structure in which the outer peripheral surface of the small-diameter portion is inserted into the inner peripheral surface of the large-diameter portion to integrate the two. The integrated structure is formed in a part of the circumferential direction of the inner peripheral surface of the large-diameter portion, and extends in the axial direction with a flat surface at the top, and is formed to extend in the axial direction in a part of the circumferential direction of the outer peripheral surface of the small-diameter portion, and includes an opposing surface opposing the flat surface of the boss portion. With the flat surface of the boss portion and the opposing surface being made to coincide, the outer peripheral surface of the small-diameter portion is inserted into the inner peripheral surface of the large-diameter portion, and the large-diameter portion and the small-diameter portion are rotated relative to each other to bring the large-diameter portion and the small-diameter portion into an integrated state.

[0009] According to the fishing rod having the above-described configuration, when joining adjacent rod bodies, the boss portion formed on a part of the circumferential direction of the inner peripheral surface of the large-diameter portion and the opposing surface formed on a part of the circumferential direction of the outer peripheral surface of the small-diameter portion are aligned, and the small-diameter rod body is inserted into the large-diameter rod body. Then, in a state where both are inserted to a certain extent (for example, when a tapered portion is formed on the outer surface of the small-diameter portion and the insertion of the small-diameter portion is restricted), when the large-diameter portion and the small-diameter portion are relatively rotated, the flat surface of the boss portion and the opposing surface of the small-diameter portion are displaced in the circumferential direction, and the flat surface of the boss portion receives an expanding action by contacting the circumferential surface of the small-diameter portion and enters a joined state. In this case, since the flat surface of the boss portion and the opposing surface of the small-diameter portion are aligned for insertion and removal, the joining operation of adjacent rod bodies can be easily performed. Also, by relatively rotating both, a joined state is achieved over the axial direction of the boss portion, so that the fitting force is improved and loosening and rattling are less likely to occur.

Effect of the Invention

[0010] According to the present invention, a fishing rod having a joining structure in which the large-diameter rod body and the small-diameter rod body can be easily joined, the fitting force can be improved, rattling is less likely to occur, and sticking is difficult to occur can be obtained.

Mode for carrying out the invention

[0012] FIG. 1 is a view showing a main part of an embodiment of a fishing rod according to the present invention. The fishing rod 1 according to the present embodiment has a structure in which a plurality of rods are joined in a side-by-side manner, and each of the original rod 3, the middle rod 5, and the tip rod 7 is joined by a joining structure 10 in an end region P thereof. In this case, the number of middle rods (the total number of joints) is not limited, and a two-piece structure in which the tip rod 7 is directly joined to the original rod 3 may be used.

[0013] The original rod 3 and the middle rod 5 are formed of a tubular body made of a fiber-reinforced resin. For example, a fiber-reinforced resin prepreg (prepreg sheet) in which a synthetic resin such as an epoxy resin is impregnated into reinforcing fibers (mainly carbon fibers, glass fibers, etc.) is wound around a mandrel and then subjected to a heating process, and then demolded, etc., and is formed according to a conventional method. Further, the tip rod 7 may be formed as a tubular body, similar to the original rod 3 and the middle rod 5, or may be formed as a solid body, or a combination of a tubular body and a solid body.

[0014] Next, the joining structure 10 of the fishing rod 1 described above will be described with reference to FIGS. 2 to 4. FIG. 2 is a view schematically showing the joining structure 10 between the adjacent original rod 3 and the middle rod 5. In this case, since the original rod and the middle rod are joined adjacent to each other and have a tapered structure, the original rod 3 is also referred to as a large diameter rod, and the middle rod 5 is also referred to as a small diameter rod. As described above, in the present embodiment, a side-by-side type is used as the joining structure 10. For this reason, the end portion (also referred to as a small diameter portion) of the small diameter rod 5 becomes the male side and is inserted and fitted into the female side which is the end portion (also referred to as a large diameter portion) of the large diameter rod 3.

[0015] In addition, the joint structure 10 of the fishing rod according to the present invention can be applied not only to the butt-joint type described above, but also to the reverse butt-joint type, the inro type, and the telescopic type. Therefore, in the joint area of the reverse butt-joint type, the end of the small-diameter rod 5 becomes the large-diameter part (female side), and the end of the large-diameter rod 3 becomes the small-diameter part (male side). Also, in the joint area of the inro type, in the configuration where the inro (core material) is press-fitted and fixed to the end of the large-diameter rod 3, the end of the small-diameter rod 5 becomes the large-diameter part (female side), and the exposed inro becomes the small-diameter part (male side). In the configuration where the inro (core material) is press-fitted and fixed to the end of the small-diameter rod 3, the end of the large-diameter rod 3 becomes the large-diameter part (female side), and the exposed inro becomes the small-diameter part (male side). Also, in the telescopic type, the end of the small-diameter rod 5 becomes the small-diameter part (male side), and the end of the large-diameter rod 3 becomes the large-diameter part (female side).

[0016] Since the joint structure 10 of the present embodiment adopts the butt-joint type, the end of the small-diameter rod 5 (small-diameter part 5A) is the male side, the end of the large-diameter rod 3 (large-diameter part 3A) is the female side, and the outer peripheral surface of the small-diameter part 5A is inserted into the inner peripheral surface of the large-diameter part 3A to join the two (in FIG. 2, the mating length in the axial direction is indicated by the symbol L).

[0017] The original rod 3 and the middle rod 5 that are joined adjacent to each other are formed by winding a prepreg sheet, and it is preferable that a reinforcing prepreg sheet is wound at least in the portion of the mating length L. The prepreg sheets constituting each rod are those in which the reinforcing fibers are directed in the axial direction, those directed in the circumferential direction, those directed in the inclined direction, and those woven into a woven fabric, and these are used in appropriate combinations.

[0018] FIG. 3 and FIG. 4 are diagrams showing the configurations of the small-diameter rod 5 and the large-diameter rod 3, respectively. FIG. 3(a) is a perspective view, FIG. 3(b) is an end view seen from the axial direction, FIG. 4(a) is a perspective view, and FIG. 4(b) is an end view seen from the axial direction.

[0019] The integrated structure 10 includes a boss portion 3c formed on a part of the circumferential direction of the inner circumferential surface 3a of the large-diameter portion 3A, extending in the axial direction and having a flat top surface 3b, and a part of the circumferential direction of the outer circumferential surface 5a of the small-diameter portion 5A formed to extend in the axial direction and having an opposing surface 5b opposing the flat surface 3b of the boss portion 3c. These flat surfaces 3b and opposing surface 5b may be slightly separated or may be in a state of being in contact to some extent when the small-diameter rod is inserted into the large-diameter rod (it is preferable if even when in contact, the sliding resistance is not large). Also, they may not be strictly horizontal planes and may be in a state where some curvature is formed.

[0020] The boss portion 3c is formed along the axial direction over a predetermined length L1 from the open end 3d of the large-diameter portion 3A and is a portion where the wall thickness T1 of the large-diameter portion 3A is formed thick. In this case, the maximum height H of the boss portion 3c depends on the wall thickness T1 of the large-diameter rod 3 constituting the integrated structure 10, but it may be formed to be about 0.02 to 0.2 mm. Also, regarding the forming angle θ of the boss portion 3c with respect to the axis O, if it is too large, it becomes difficult to rotate relatively, and if it is too small, the fitting force does not improve, so it is preferably formed at 3° to 46° (a value derived by calculation). For such a boss portion 3c, for example, when forming the large-diameter rod 3, it can be created by forming a long groove over a predetermined length from the end on the above-mentioned mandrel.

[0021] Regarding the axial length L1 of the boss portion 3c, it is sufficient if it is easy to insert and remove and a certain degree of joint force (fitting force) can be ensured. In the configuration as in this embodiment, for example, it is formed in the range of 5 mm to 7 mm. As will be described later, a taper 5f is formed on the outer peripheral surface 5a of the small-diameter portion 5A of this embodiment, and the inner diameter portion at the tip of the large-diameter portion 3A is inserted after being applied to the taper 5f, so that the diameter expands, and finally the axial position is fixed. In this way, when the large-diameter portion and the small-diameter portion are inserted, if the axial length from the position where the large-diameter portion is applied to the taper 5f and expands and is fixed is defined as the press-fitting length La, regarding the axial length L1 of the boss portion 3c, it is possible to fit if it is equal to or greater than the press-fitting length La during fitting, and it is sufficient if it is formed in the range of at least 5 mm to 7 mm.

[0022] However, if the press-fitting length La and the axial length L1 of the boss portion 3c are close, the inserted small-diameter portion on the male side may not be sufficiently held on the surface of the boss portion 3c, and there may be problems with the fitting force and rattling. For this reason, it is preferable that the axial length L1 of the boss portion 3c is formed to be equal to or greater than the axial combined length L of the inner peripheral surface 3a of the large-diameter portion 3A and the outer peripheral surface 5a of the small-diameter portion 5A (L ≦ L1).

[0023] In this way, by forming the axial length L1 of the boss portion 3c to be equal to or greater than the combined length L, in the joined state, as shown in FIG. 2, the open end 5d of the small-diameter rod 5 is surely applied to the boss portion 3c. That is, the generation of a gap between the open end 5d of the small-diameter rod 5 and the inner peripheral surface 3a of the large-diameter rod 3 is suppressed, and even if the rod bends, the open end 5d of the small-diameter rod 5 is in a state of being applied to the boss portion 3c, and the generation of rattling can be prevented. Regarding the axial length L1 of the boss portion 3c, if it becomes shorter than the press-fitting length La during joining, there is a possibility that a sufficient joint force cannot be obtained during the rotation operation. Therefore, as described above, it is preferable that La ≦ L1.

[0024] On the outer peripheral surface 5a of the small-diameter portion 5A, a facing surface 5b is formed in a part in the circumferential direction so as to extend in the axial direction and face the flat surface 3b of the boss portion 3c. It is preferable that the flat surface 3b of the boss portion 3c and the facing surface 5b are each formed in the same shape (substantially rectangular shape in this embodiment) in plan view. By forming both surfaces in this way, as will be described later, it is possible to generate a stable joint force within the range of the combined length L in a state where the respective rods are relatively rotated.

[0025] The facing surface 5b can be formed by milling the outer peripheral surface 5a of the small-diameter portion 5A. In this case, for the milling depth T2 of the facing surface 5b, it is sufficient that a gap of about +0.1 mm to 0.2 mm is ensured with respect to the height H of the boss portion 3c (so that a slight gap is ensured between the flat surface and the facing surface).

[0026] On the outer peripheral surface 5a of the small-diameter portion 5A of this embodiment, a taper 5f that becomes smaller in diameter as it moves toward the tip (open end) is formed, and the facing surface 5b is formed by milling in the region of this taper 5f. In this case, it is preferable that the axial length L2 of the facing surface 5b formed on the taper 5f is formed to be equal to or greater than the axial combined length L of the inner peripheral surface 3A of the large-diameter portion 3 and the outer peripheral surface 5A of the small-diameter portion 5 (L ≦ L2).

[0027] In this way, by forming the axial length L2 of the facing surface 5b to be equal to or greater than the combined length L, when the small-diameter portion 5A is inserted into the large-diameter portion 3A and the insertion position is fixed by the taper 5f, no gap is generated in a state where the flat surface 3b of the boss portion 3c and the facing surface 5b face each other, so it is possible to prevent rattling.

[0028] Next, with reference to FIG. 5, the operation method for joining the large-diameter rod 3 and the small-diameter rod 5 in the above-described joining structure 10 will be described. First, align the large-diameter rod 3 (large-diameter portion 3A) and the small-diameter rod 5 (small-diameter portion 5A) axially. This alignment is to make the flat surface 3b of the boss portion 3c of the large-diameter portion 3A coincide with the opposing surface 5b of the small-diameter portion 5A in the circumferential direction. To facilitate the alignment, it is preferable to mark the surfaces of adjacent rods 3 and 5 with alignment marks 13 and 15 for inserting the flat surface 3b and the opposing surface 5b in coincidence (see Fig. 5(a)).

[0029] Then, with the flat surface 3b of the boss portion 3c of the large-diameter portion 3A and the opposing surface 5b of the small-diameter portion 5A aligned, insert the outer peripheral surface 5a of the small-diameter portion 5A into the inner peripheral surface 3a of the large-diameter portion 3A (see Fig. 5(b)). In this insertion operation, smooth incorporation can be achieved by the sliding of the flat surface 3b and the opposing surface 5b against each other. When the small-diameter portion 5A is inserted into the large-diameter portion 3A, a taper 5f that tapers as it moves toward the tip (open end) is formed on the outer peripheral surface 5a of the small-diameter portion 5A as described above. Thus, the open end 3d of the large-diameter portion 3A abuts against the taper 5f, thereby determining the alignment position of the insertion (see Fig. 5(b) and Fig. 2).

[0030] Next, with the alignment position determined, relatively rotate the large-diameter portion 3A and the small-diameter portion 5A as indicated by the arrow in Fig. 5(c). By relatively rotating the two rods, the flat surface 3b and the opposing surface 5b that were in the opposing state shift in the rotational direction, and the flat surface 3b of the boss portion 3c is subjected to a diameter-expanding action by the outer peripheral surface 5a of the small-diameter portion 5A. As a result, the large-diameter portion 3A and the small-diameter portion 5A are in a joined state along the axial direction, the fitting force is improved, and the two rods are difficult to come off. In this case, since the diameter-expanding action on the flat surface 3b is received over the combined length L of the two rods, the fitting force can be improved and the occurrence of rattling (play) can be suppressed.

[0031] Note that the diameter-expanding action of the flat surface 3b of the boss portion 3c described above may be performed until the facing relationship between the flat surface 3b and the facing surface 5b is lost. Although it also depends on the forming angle θ with respect to the axis O of the boss portion 3c shown in FIG. 4, a rotation operation of 90° or less is sufficient. Further, by increasing the rotation operation angle within 90°, the region of the diameter-expanding action on the flat surface 3b increases, and the two rods can be made more difficult to rotate and come off in the combined state.

[0032] According to the above-described combined structure 10, in a state where the alignment position is determined, such as aligning adjacent rods and performing an insertion operation to stop in the axial direction, the two rods can be brought into a combined state only by relatively rotating the two rods. Therefore, unlike the conventional combined structure of tapers, it is not necessary to apply pressure in the axial direction and fix at a position where it is forcibly stopped. Instead, it is only necessary to relatively rotate the rods at the alignment position, so that the combination operation can be easily performed, and the combined structure is difficult to rotate and come off. Also, unlike the conventional case, the fitting force does not easily vary.

[0033] Further, since the combination is made over the axial length (combined length L) of the flat surface 3b and the facing surface 5b, it is difficult for a gap to occur, and it is difficult for rattling or play to occur. In particular, by forming the axial length L1 of the boss portion 3c to be equal to or greater than the combined length L, the open end 5d of the small-diameter rod 5 is surely brought into contact with the boss portion 3c (see FIG. 2), and the occurrence of rattling can be surely prevented. Furthermore, since the combined state can be released by rotating the rods relative to each other, the operation for releasing the combined state can be more easily performed than the operation for pulling out in the axial direction.

[0034] The present invention can also be applied to a fishing rod of a type to which a reel is attached (a fishing rod having a fishing line guide attached to the rod). FIG. 6 is a view showing a second embodiment applied to a fishing rod with a fishing line guide, and is a view showing a combined structure portion. In these figures, FIG. 6(a) is a view seen from the axial direction of the state before insertion of the large-diameter rod and the small-diameter rod, FIG. 6(b) is a view seen from the axial direction of the state where the small-diameter rod is aligned and inserted into the large-diameter rod, and FIG. 6(c) is a view seen from the axial direction of the state where the large-diameter rod and the small-diameter rod are relatively rotated. Next, the second embodiment will be described (for the constituent members similar to those in the first embodiment, the same reference numerals are given and detailed descriptions thereof are omitted).

[0035] As shown in Fig. 6(a), on the surfaces of the large-diameter rod 3 (large-diameter portion 3A) and the small-diameter rod 5 (small-diameter portion 5A), which are adjacent rods, fishing line guides 23 and 25 for inserting a fishing line by a known attachment method such as line fixing are provided. Also, similar to the configuration shown in Fig. 5, the marks 13 and 15 formed on the surfaces of the respective rods 3 and 5 are formed such that the fishing line insertion directions of the fishing line guides 23 and 25 are displaced between adjacent rods (the positions of the fishing line guide 23 and the fishing line guide 25 are displaced in the circumferential direction) (see Figs. 6(a) and 6(b)). That is, when the small-diameter rod is inserted into the large-diameter rod and fixed in the mating position with the marks 13 and 15 aligned, as shown in Fig. 6(b), the fishing line insertion directions of the fishing line guides 23 and 25 are in a state of being displaced in the circumferential direction.

[0036] In this state, by relatively rotating the adjacent rods 3 and 5 so that the fishing line insertion directions of the fishing line guides 23 and 25 are made to coincide as shown in Fig. 6(c), it is possible to make both rods in a joined state. Thus, the present invention can also be applied to a fishing rod to which a fishing line guide is attached. In this case, regarding the angle α (see Fig. 6(b)) by which the adjacent fishing line guides 23 and 25 are displaced in the circumferential direction when the rods are inserted into each other, it is preferable to form the guide mounting position, the size of the boss portion 3c, and the opposing surface 5b so that it is 45° to 90°, whereby it is possible to improve the strength of the joined state.

[0037] In the configuration of the above-described embodiment, the boss portion 3c formed in the large-diameter portion 3A, and the opposing surface 5c of the small-diameter portion 5A that opposes the flat surface 3b of the boss portion 3c are formed at one location in the circumferential direction, but may be formed at a plurality of locations at equal intervals along the circumferential direction. In this way, by forming at a plurality of locations (preferably 2 to 4 locations), it is possible to improve the joining strength between the rods and more effectively suppress rattling and looseness.

[0038] In addition, when forming at one location in the circumferential direction as in the above-described embodiment, it is preferable that the boss portion 3c and the opposing surface 5b are formed in consideration of the bending direction of the fishing rod as shown in FIG. 2. That is, if the bending direction when a load acts on the fishing rod is the direction indicated by the arrow D, if the boss portion 3c and the opposing surface 5b are provided on the tensile side with respect to the axis O in the joined state, even if the fishing rod bends, the opening end 5d of the small-diameter portion is in contact with the boss portion 3c, so rattling and looseness can be reliably suppressed.

[0039] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments and can be variously modified. The integrated structure 10 according to the present invention is characterized in that a boss portion 3c is formed on the inner peripheral surface of the large-diameter portion, an opposing surface 5b is formed on the outer peripheral surface of the small-diameter portion with respect to the flat surface 3c of the boss portion, and by combining these, the fitting force is increased by the insertion operation and the rotation operation, thereby preventing disengagement and rotation prevention. In the above-described embodiment, the prepreg sheet constituting the integrated structure 10 can be appropriately deformed in terms of the number of windings, the type of reinforcing fiber, the resin impregnation amount, the wall thickness, etc., according to the type of fishing rod, the diameters of the large-diameter rod and the small-diameter rod, the installation position of the integrated structure, and the like. Also, the combined length L, the length L1 of the boss portion 3c, the length L2 of the opposing surface, the formation angle θ of the boss portion, etc. can also be appropriately deformed.

[0040] Furthermore, the inner peripheral surface 3a of the large-diameter portion 3A may be formed in a straight shape or may be formed with a taper. Also, the outer peripheral surface 5a of the small-diameter portion 5A may be formed in a straight shape. In this case, in the combination of straight shapes, it may be configured such that the position of the insertion alignment is determined, such as by forming a stepped portion or a mark on the outer peripheral surface 5a.
