Description

Technical Field

[0001] The present invention relates to a fishing line guide and a fishing rod equipped with the fishing line guide.

Background Art

[0002] Conventionally, fishing rods that can be equipped with various fishing reels such as spinning reels and double-bearing reels are known. In such fishing rods, fishing line guides for guiding the fishing line paid out from the fishing reel are attached at predetermined intervals in the longitudinal direction of the fishing rod. Usually, the fishing line guide has a configuration including a fishing line insertion portion (guide ring holding portion to which a guide ring is attached) through which the fishing line is inserted, a guide leg fixed to the rod of the fishing rod, and a connecting portion connecting the fishing line insertion portion and the guide leg. Further, such a fishing line guide is formed in a plate shape from metal, synthetic resin, or fiber-reinforced resin (see FIG. 8 of Patent Document 1), and is fixed to the rod by placing the guide leg on the rod, fixing the guide leg, and applying resin.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the plate-shaped fishing line guide as described above does not have sufficient rigidity, if it is thickened to ensure rigidity, the weight increases and it is affected by wind resistance, which may reduce the operability of the fishing rod. In addition, the appearance also deteriorates due to the thickening of the fishing line guide. Furthermore, the fishing line guide described above has a shape in which the connecting portion rises in an arc from the guide leg fixed to the rod surface and transitions to the fishing line insertion portion. The rising portion transitioning from the guide leg to the connecting portion is the portion where the largest load (bending stress) is applied. If the rigidity of this portion is insufficient, the fishing line guide is likely to be damaged, such as bending or breaking.

[0005] The present invention has been made by focusing on the above-described problems, and an object thereof is to provide a fishing line guide that has good operability of a fishing rod, is efficiently lightweight, and is less likely to be damaged, and a fishing rod equipped with such a fishing line guide.

Means for Solving the Problems

[0006] In order to achieve the above object, the fishing line guide according to the present invention includes a guide leg that serves as a fixing portion for the rod, a fishing line insertion portion through which the fishing line is inserted, and a connecting portion that rises from the guide leg and connects to the fishing line insertion portion, and is characterized in that a rib protruding toward the tip side of the rod is formed from the vicinity of the fixing portion of the guide leg toward the fishing line insertion portion.

[0007] According to the fishing line guide having the above-described configuration, by forming a rib protruding toward the tip side of the rod from the vicinity of the fixing portion of the guide leg toward the fishing line insertion portion, rigidity can be efficiently ensured without increasing the weight. That is, when the fishing line gets caught or the like, the largest load acts in the vicinity of the fixing portion of the guide leg on the fishing line guide. By forming a rib from this portion toward the fishing line insertion portion, an efficient reinforcing effect can be obtained. In addition, since a sufficient reinforcing effect is obtained, damage such as the guide leg or the connecting portion being damaged, bent, or broken is prevented.

[0008] Further, the present invention provides a fishing rod equipped with the above-described fishing line guide. Such a fishing rod has a plurality of the above-described fishing line guides that efficiently increase rigidity without increasing the weight, so that the weight of the entire fishing rod does not increase and the operability does not deteriorate.

Effects of the Invention

[0009] According to the present invention, a fishing line guide with good operability of a fishing rod, which is efficiently lightweight and less likely to cause damage, and a fishing rod equipped with such a fishing line guide can be obtained.

Mode for Carrying Out the Invention

[0011] FIG. 1 is a view showing an embodiment of a fishing rod according to the present invention. The fishing rod 1 shown in FIG. 1 is configured as a telescopic type in which the middle rod 5 and the tip rod 7 are housed in the base rod 3 and are sequentially telescoped and combined. Each rod is configured as a tubular body, and is created, for example, by winding a prepreg sheet made of a fiber reinforced resin impregnated with a synthetic resin in reinforcing fibers. The tubular body made of such a material is created by a known manufacturing method, and the rod constituting the fishing rod of the present invention may have a solid structure in addition to such a tubular structure. Further, the number of rods (the number of combined rods) housed inside the base rod 3 is arbitrary, and the combining method may be other than the telescopic type, such as a side-by-side type or an inro joint type. Further, the fishing rod may be a single rod instead of combining a plurality of rods.

[0012] A reel seat 9 having a reel foot mounting portion is disposed on the proximal end side of the base rod 3. On this reel seat 9, a fixed hood and a movable hood are provided on both axial sides of the reel foot mounting portion. By placing the reel foot of the fishing reel 100 on the reel foot mounting portion and moving the movable hood in the axial direction, the reel foot is tightened and fixed on the reel foot mounting portion. Note that the movable hood may be disposed on either the tip side or the proximal end side, or both sides may be configured as movable hoods.

[0013] Fishing line guides 10 and 10A for guiding the fishing line are attached to the base rod 3, the middle rod 5, and the tip rod 7 (the fishing line guide 10A is a top guide). A plurality of the fishing line guides 10 are arranged on the surface of each rod at a predetermined interval along the axial direction. Note that these fishing line guides 10 include those of a type fixed by a fixing method as described later (fixed guides) and those of a type slidable along the rod surface when the rod is stored (floating guides).

[0014] Next, with reference to FIGS. 2 to 6, the configuration of the fishing line guide 10 attached to the fishing rod described above will be described. In these figures, a fixed guide fixed to the surface of the rod is shown, and the attachment position with respect to each rod is on the front end side. For this reason, depending on the outer diameter of the rod to which it is attached, its size and the like are appropriately changed.

[0015] The fishing line guide 10 of the present embodiment includes a guide leg 11 extending in the axial direction of the rod to which it is attached, a fishing line insertion portion 13 through which the fishing line is inserted, and a connecting portion 15 that rises from the tip side end of the guide leg 11 and is connected to the fishing line insertion portion 13. These are formed in a flat plate shape. The fishing line guide 10 of the present embodiment is integrally formed by injection molding a fiber-reinforced resin impregnated with a matrix resin (for example, a thermosetting resin such as an epoxy resin, an unsaturated polyester, a phenol, a vinyl ester, or a thermoplastic resin such as a polyether sulfone (PES), a polyphenylene sulfide (PPS), a polyether ketone (PEEK), a polycarbonate (PC), a polyamide (PA), etc.) with short fibers or long fibers serving as reinforcing fibers (for example, various reinforcing fibers such as carbon fibers and glass fibers).

[0016] Further, the fishing line guide 10 of the present embodiment has a single-leg structure in which the guide leg 11 extends in the axial direction of the base end side, and at the tip side end of the guide leg 11, it becomes a connecting portion 15 that rises while curving, and has a structure in which the fishing line insertion portion 13 having a circular opening 13A is provided on the upper end side of the connecting portion 15. In this case, a guide ring formed of ceramics, metal, or the like may be attached to the circular opening 13A so as to enhance the slidability of the fishing line.

[0017] In the above-described configuration, the guide leg 11 is an area that serves as a fixed portion with respect to the rod 5 (see FIG. 7). The connecting portion 15 is defined as the area on the upper side from the inflection point P1 where it begins to rise in a curved shape with respect to the rod surface (horizontal plane P) when viewed from the side in a state where the fishing line guide is fixed to the rod surface. Further, the fishing line insertion portion 13 is defined as the area above the position P2 which is the lowermost end inside the circular opening 13A. For this reason, when viewed from the side, the lower edge line 15A on the lower surface side (tip side of the rod) of the connecting portion 15 is curved, and the upper edge line 15B on the upper surface side (base end side) is also curved in the same manner (the connecting portion has a substantially uniform wall thickness). In the example shown in FIG. 3, the inflection point P1 of the edge line 15A exists at a position slightly raised from the lowermost end (horizontal plane P) of the guide leg 11. However, depending on the shape of the rib 20 to be protruded, which will be described later, the edge line 15A may extend to the lowermost end of the guide leg 11. That is, the inflection point P1 of the lower edge line 15A that defines the connecting portion 15 may exist at the lowermost end (horizontal plane P) of the guide leg 11.

[0018] As described above, the fishing line insertion portion 13 is integrated with the connecting portion 15, and the connecting portion 15 is formed so as to curve and rise from the guide leg 11. In this case, the rising angle α of the surface 15C on the tip side of the rod of the connecting portion 15 with respect to the guide leg 11 is not particularly limited. However, it is preferably formed in the range of 30° ≤ α ≤ 85° so that the fishing line can be smoothly guided and can easily come out even if the fishing line is entangled in a loop shape. Further, the surface 15C of the connecting portion 15 in the present embodiment is formed flush with the surface 13C on the tip side of the fishing line insertion portion 13 and serves as the surface Pd that defines the rising angle α.

[0019] In the fishing line guide 10, a rib 20 protruding toward the tip side of the rod is formed from the vicinity of the fixed portion of the guide leg 11 toward the fishing line insertion portion 13. As shown in FIG. 3, the rib 20 is formed so as to protrude from the ridge line 15A of the connecting portion 15 toward the tip side of the rod when the fishing line guide is viewed from the side, and at its upper end position 20a, it is integrated with the surface 15C of the connecting portion 15. That is, the protruding-side end face (the end face on the tip side of the rod) 20A of the rib 20 in the present embodiment is formed to be flush with the surface 15C of the connecting portion 15 and the surface 13C on the tip side of the fishing line insertion portion 13.

[0020] Generally, in the fishing line guide 10 of the above type, when the fishing line gets caught, a large load (the bending stress in the clockwise direction in FIG. 3) acts on the vicinity of the fixed portion from the guide leg 11 to the connecting portion 15 (the curved portion where it transitions from the inflection point P1 to the connecting portion 15). By forming the rib 20 in this portion, the rigidity is increased and an effective reinforcing effect can be obtained. That is, it is possible to ensure the rigidity that compensates for the low elastic modulus of the injection molding material (fiber-reinforced resin material).

[0021] The rib 20 may be formed on the surface 15C on the tip side of the connecting portion 15 in the region where the guide leg 11 of the fishing line guide transitions to the fishing line insertion portion 13. However, as shown in FIG. 5, it is preferably formed in the central portion of the surface 15C on the tip side of the connecting portion 15. That is, the rib 20 may be formed over the entire surface 15C on the tip side. However, as shown in FIG. 5, by forming it in the central portion, it is possible to efficiently enhance the reinforcing effect without increasing the weight of the entire fishing line guide. In this case, the upper end position 20a of the rib 20 may be formed to be located at the circular opening 13A of the fishing line insertion portion 13. However, since no particularly large load acts in the vicinity of the circular opening 13A, as shown in FIG. 5, it may be formed up to the substantially middle position of the connecting portion 15.

[0022] Also, as shown in FIG. 3, it is preferable that the rib 20 is formed to a height that does not protrude toward the tip side from the surface 13C on the tip side of the fishing line insertion portion 13, that is, a height that does not protrude toward the tip side from the surface Pd. This is because if it is formed too high (thick), the rigidity distribution will change significantly, and conversely, the strength may decrease. Also, if the rib 20 is high, it is likely to be affected by wind resistance, and the operability of the fishing rod will decrease. Therefore, it is preferable that the height is formed below the surface Pd.

[0023] Also, regarding the width W of the rib 20, in the present embodiment, as shown in FIGS. 5 and 6, it is formed with a uniform width, but it is preferable to form it so that the fixed side with respect to the rod blank is wider and it becomes narrower toward the fishing line insertion portion side. By configuring it in this way, an efficient reinforcing effect can be obtained without increasing the weight, and furthermore, it becomes possible to withstand a larger load without stress concentrating in part.

[0024] Furthermore, regarding the height H of the rib 20, it is preferable to form it so that the fixed side with respect to the rod blank is higher and it becomes lower toward the fishing line insertion portion 13 side. By configuring it in this way, the strength can be efficiently improved without stress concentrating in part, and in combination with the structure in which the width W changes, it becomes a tapered shape, so that molding can be easily performed. Also, on the upper end side of the rib 20, since it is less likely to be affected by wind resistance, a decrease in the operability of the fishing rod is prevented.

[0025] It is preferable to form a through-hole 22 in the rib 20. As shown in Fig. 3(a), the through-hole 22 of the present embodiment is formed on the side of the fixing part where a fixing thread 50 (see Fig. 7) for the guide leg 11 is wound. By forming the through-hole 22 at such a position, when fixing the fishing line guide 10 to the rod, it becomes possible to insert the wound thread 50 and wind it around, and it is possible to prevent the fishing line guide from coming off in the fixed state. Further, by forming the through-hole 22, weight reduction can be achieved, so a plurality of them may be formed, and some or all of them may be configured as recesses instead of through-holes. Note that the size (inner diameter) and shape of the through-hole are not limited, and for example, as shown in the through-hole 22A in Fig. 3(b), it can be appropriately deformed such as being formed to a size that allows two or more threads 50 to pass through.

[0026] As shown in Fig. 3, the end face (end face on the rod tip side) 20A on the protruding side of the rib 20 is formed flush with the surface 15C of the connecting part 15 and the surface 13C on the rod tip side of the fishing line insertion part 13, and the end face 20A is bent at approximately 90° and connected to the lower end face 20B that abuts against the surface of the rod to be fixed. In this way, since the lower end face 20B of the rib 20 abuts against the rod surface when the fishing line guide 20 is fixed to the rod, even if a large bending stress acts on the fishing line guide, it is difficult to wobble or deform, and it is possible to maintain a stable fixed state. That is, in a conventional fishing line guide without the rib 20, when fixed to the surface of the rod, the fixing resin is filled in the gap part of the curved connecting part, which not only makes the fixed state of the fishing line guide unstable but also causes a decrease in appearance. However, the presence of the rib 20 in such a gap part stabilizes the fixed state of the fishing line guide and prevents the appearance from deteriorating.

[0027] Further, the lower end face 20B of the rib 20 may be extended axially as it is and integrated with the guide leg 11 to serve as a fixing part that abuts against the surface of the rod. In this case, as shown in Figs. 5 and 6, it is preferable to form a groove 24 that extends along the axial direction of the rod in the part fixed to the rod surface.

[0028] Further, since the fishing line guide 10 of the present embodiment is difficult to come off and the fixing state can be stabilized by the above-described configuration, it is possible to reduce the thickness of the tip side 11A of the guide leg 11 to reduce the weight. Further, as shown in FIG. 2, by forming a large number of polygonal concave portions 15a in the connecting portion 15, it is also possible to reduce the weight. That is, according to the fishing rod in which a plurality of fishing line guides 10 having the above-described configuration are installed on the rod, the weight can be reduced, the operability can be improved, and the appearance is not deteriorated.

[0029] Next, with reference to FIG. 7, a method of fixing the fishing line guide 10 having the above-described configuration to the surface of the rod (here, the middle rod 5) will be described. When fixing the fishing line guide 10 to the surface of the rod 5, the guide leg 11 is placed on the surface of the rod 5, and a fixing thread 50 is wound around the periphery. Then, after winding the thread 50, a fixing resin is applied from its surface to stabilize the fixing state.

[0030] When winding the thread 50, since the thread can be passed through the through hole 22 formed in the rib 20 and wound around like a pillow, it is possible to improve the pull-out strength of the fishing line guide while improving the rigidity. In this fixing operation, in the conventional fishing line guide, the resin entered the gap between the rod surface and the workability was poor, but by forming the rib 20, the resin does not enter, and the workability can be improved. Further, since the resin enters the through hole 22 and an anchor effect is obtained between the rod surface, the fixing strength is improved and the fixing state of the fishing line guide is also stabilized.

[0031] Furthermore, as shown in FIG. 7(b), when the lower surface (guide leg) of the rib 20 is applied to the rod surface, by forming a groove 24 in the rib 20, the contact position 20P with respect to the rod becomes a two-point contact, and the fixing state can be stabilized.

[0032] The present invention is not limited to the above-described embodiment, and various modifications are possible. Hereinafter, configuration examples of modification examples will be described. In explaining the following various modification examples, the same components as those in the above-described embodiments are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0033] FIG. 8 is a diagram showing a first modification example of a fishing line guide, where (a) is a plan view of a guide leg portion, (b) is a side view, and (c) is a diagram showing a modification example of the concavo-convex structure. As shown in this modification example, a plurality of concavo-convex portions 16 (anti-slip structure) may be formed along the axial direction in a portion of the surface of the guide leg 11 around which the thread 50 is wound. As shown in (b), these concavo-convex portions 16 may be formed by continuously forming concave portions 16a, or as shown in (c), may be formed by continuously forming convex portions 16b.

[0034] By forming such concavo-convex portions 16, when the thread is fixed, it is possible to prevent the thread from entering the concave portion region and the fishing line guide from coming off. Note that the manner of forming the concavo-convex portions can be variously deformed, and the anti-slip structure may be formed by roughening the surface or forming knurling or the like.

[0035] FIG. 9 is a diagram showing a second modification example of a fishing line guide, which is a plan view of a guide leg portion. As described above, the anti-slip structure formed on the guide leg 11 can also be configured by forming a wide portion 16A on the tip side of the guide leg 11.

[0036] FIGS. 10(a) and (b) are diagrams showing a third modification example of a fishing line guide, which are cross-sectional views of a guide leg portion, respectively. As described above, the rib 20 may be configured to be integrated with the guide leg 11 and applied to the rod surface for winding the thread, or may be configured to be fixed by directly applying the back surface of the guide leg 11 to the rod surface without extending in the axial direction.

[0037] In such a configuration, as shown in (a), the guide leg 11 may be configured with a curved surface along the surface of the rod, or as shown in (b), the guide leg 11 may be configured with a curved surface along the surface of the rod, and both sides 11d thereof may be configured to have a reduced wall thickness. In this way, by reducing the wall thickness of both sides, when winding the thread, both sides can be elastically deformed so as to contact the rod surface, and thus the fixing strength can be improved.

[0038] FIG. 11 is a diagram showing a fourth modification example of the fishing line guide, where (a) is a perspective view and (b) is a side view. In the fishing line guide 10 of the above-described embodiment, the guide leg 11 had a single-leg structure extending toward the proximal end side in the axial direction of the fishing rod. However, as shown in (a) and (b), it may be a two-leg structure extending to both sides in the axial direction of the fishing rod with respect to the fishing line insertion portion 13, and the fishing line insertion portion 13 may be configured to vertically rise. And in such a structure of the fishing line guide, the rib 20 may be formed only on one of the guide leg sides, but it is preferable to form it in each of the opposing regions of both guide legs 11. Further, as shown in (c), the fishing line insertion portion 13 may have a structure that rises obliquely.

[0039] FIG. 12 is a diagram showing a fifth modification example of the fishing line guide, where (a) is a perspective view and (b) is a side view. In the above-described embodiment and modification examples, the connecting portion 15 was formed in a plate shape. However, the connecting portion may have a frame structure extending from both sides of the fishing line insertion portion 13 to the guide leg 11. In this case, the above-described rib 20 may be formed on each frame 15F. In this way, the shape of the connecting portion 15 can also be appropriately deformed.

[0040] FIG. 13 is a diagram showing a second embodiment of the fishing line guide, which is an enlarged view showing the fishing line guide (tip guide) attached to the tip rod 7 shown in FIG. 1. The rib 20 of the fishing line guide 10A of this embodiment can be integrally formed with the cylindrical portion 19 that is press-fitted into the tip portion of the tip rod 7. The fishing line guide 10A is press-fitted into the tip rod 7 and adhesively fixed. By forming the through hole 22 in the rib 20, an anchor effect can be obtained, and the adhesive strength can be increased.

[0041] 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. In the above-described embodiment, the fixed guide fixed to the rod has been shown. However, a similar rib can also be formed at the connecting portion of the floating guide. Further, although the fishing line guide 10 is formed of a fiber-reinforced resin material, it can also be formed of a metal material or the like. Further, the present invention is characterized in that the rib 20 is formed on the surface on the tip side of the connecting portion rising from the fixed portion of the fishing line guide, and the other configurations are not limited to the shapes shown in the drawings. Furthermore, the size and shape of the rib 20 can be appropriately modified.
