Description

Technical Field

[0001] This invention relates to a guide for a fishing rod. Background Technology

[0002] As an existing fishing rod guide, there is a known guide comprising: a guide ring for inserting fishing line; and a guide frame fixed to the rod body, extending outward in the direction of rod diameter to hold the guide ring; and having a frame in the guide frame composed of annular line for holding the guide ring (for example, see Patent Documents 1 and 2).

[0003] Patent Document 1 describes a structure in which the outer peripheral surface of the guide ring is made into a flat surface, and a D-shaped flat portion is formed in the portion corresponding to the inner peripheral surface of the frame.

[0004] In addition, Patent Document 2 describes a structure in which a curved peripheral groove is provided on the outer peripheral surface of the guide ring to accommodate a frame made of metal wire with a circular cross-section.

[0008] Patent Document 2: Japanese Patent No. 6553455 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] However, in the fishing rod guide shown in Patent Document 1 above, although the fixing force can be improved to a certain extent by increasing the contact area between the D-cut flat surface in the frame and the outer peripheral surface of the guide ring, there is a problem that the contact area cannot be increased beyond the area of ​​the flat surface.

[0011] Furthermore, in this case, there is a problem with locating the flat surface of the frame to the outer circumferential surface of the guide ring. In particular, positioning the guide ring along its central axis becomes difficult, and there are concerns that axial misalignment may lead to cracking of the bonded portion and a reduction in fixing force.

[0012] In the case of Patent Document 2, compared with the flat surface as in Patent Document 1, the contact area between the curved outer peripheral surface of the frame and the curved surface of the outer peripheral groove can be increased. In addition, positioning can be easily performed. However, there is a concern that sufficient space may not be provided for the placement of adhesives, etc., and the desired fixing force may not be obtained.

[0013] Furthermore, in existing fishing rod guides, the frame, made of metal wire with a circular cross-section, is shaped along the curved circumferential groove of the guide ring. As a result, the frame tends to become excessively thick, which is one of the factors that hinders weight reduction.

[0014] This invention was made with this in mind, and its purpose is to provide a guide for fishing rods that facilitates the positioning of the frame and guide rings, prevents the reduction of the fixing force of the two, and enables lightweighting.

[0015] Technical means to solve the problem

[0016] (1) The guide for fishing rods of the present invention is characterized by comprising: a guide ring for through which fishing line passes; and a guide frame fixed to the rod body and extending outward in the direction of rod diameter to hold the guide ring; the guide ring having an outer peripheral groove along an outer peripheral edge located outward of the central axis of the guide ring in the direction of rod diameter; the guide frame having: a frame consisting of annular wire for holding the guide ring; and a support foot fixed to the rod body, connected to and supporting the frame; and the first opposing surface of the outer peripheral groove and the second opposing surface of the frame opposite to at least a portion of the frame having different shapes.

[0017] According to the fishing rod guide of the present invention, the first opposing surface of the outer peripheral groove of the guide ring, which is disposed opposite to at least a portion of the frame, and the second opposing surface of the frame, which is disposed opposite to the first opposing surface, have different shapes. Therefore, the opposing surface area of ​​the first opposing surface and the second opposing surface can be increased. Thus, a larger contact area between the guide ring and the frame can be ensured, thereby improving the fixing force between them.

[0018] Furthermore, according to the fishing rod guide of the present invention, the first opposing surface of the guide ring is simply arranged opposite to the second opposing surface of the frame, thus making it easy to position the frame and the guide ring.

[0019] Furthermore, in the case of the present invention, it is not necessary to make the cross-sectional shape of the frame consistent with the shape of the outer peripheral groove of the guide ring. Therefore, the thickness or cross-sectional shape of the frame can be reduced, thereby achieving weight reduction.

[0020] Furthermore, according to the present invention, by fixing the frame with its second opposing surface housed within the outer peripheral groove of the guide ring, the protruding portion of the second opposing surface extending from the outer peripheral groove can be minimized. Therefore, it is possible to prevent damage to the frame protruding from the outer peripheral groove, as was the case previously, or to prevent fishing line from tangling around the protruding portion, or to prevent seawater accumulation due to seawater adhesion.

[0021] (2) Preferably, the first opposing surface has a concave shape portion recessed toward the center of the guide ring, and the second opposing surface has a planar shape portion along the central axis of the guide ring.

[0022] In this case, a larger space (area) can be ensured between the guide ring and the frame, and an adhesive can be filled in this space (area), thereby increasing the adhesion strength between the second opposing surface and the outer peripheral groove and improving the fixing force of both.

[0023] (3) The feature may also be that the first opposing surface has a planar shape portion along the central axis direction of the guide ring, and the second opposing surface has a concave shape portion recessed in the direction opposite to the central direction of the guide ring.

[0024] In this case, a larger space (area) can be ensured between the guide ring and the frame, and an adhesive can be filled in this space (area), thereby increasing the adhesion strength between the second opposing surface and the outer peripheral groove and improving the fixing force of both.

[0025] (4) The feature may also be that there is a space between the first opposing surface and the second opposing surface, and the space is filled with adhesive.

[0026] By designing it in this way, sufficient space (filled area) can be ensured between the second opposing face with a square cross-section and the outer peripheral groove. By filling this filled area with adhesive, the fixing force between the second opposing face and the outer peripheral groove can be further improved.

[0027] Furthermore, by filling the gap between the frame and the guide ring with adhesive, the gap (step) formed between the frame and the guide ring can be eliminated, and seawater will not remain in the step section as before, thus inhibiting the accumulation of seawater.

[0028] (5) The feature may also be that at least one of the first opposing surface and the second opposing surface is disposed on at least a portion of a half-circumference on the side away from the rod body.

[0029] In this case, the connection area between the frame and the guide ring can be connected intermittently or partially in the circumferential direction. Therefore, compared with the case of connection throughout the entire circumference, the cross-sectional area of ​​the component can be reduced, thereby achieving weight reduction.

[0030] (6) The feature may also be that the second opposite surface is formed by shaping a portion of the wire of the frame into a planar shape.

[0031] In this case, by forming a second opposing surface by shaping a portion of the frame wire into a planar shape, the contact area with the first opposing surface can be increased.

[0032] (7) The feature may also be that the second opposite face is formed by forming a portion of the wire of the frame into a square cross section.

[0033] In this case, the frame is, for example, a square with a rectangular cross-section. Therefore, the surface area of ​​the portion housed within the outer peripheral groove of the guide ring can be larger, thus ensuring a larger contact area between the frame and the outer peripheral groove. Consequently, for example, a larger filling area for adhesive can be ensured between the square-section frame and the outer peripheral groove, thereby increasing the fixation strength between the frame and the outer peripheral groove and improving their securing force.

[0034] Furthermore, in the case of the present invention, the width of the square portion can be equivalent to the width of the slot, so the thickness of the frame wire can be thinner than before, thereby achieving a lightweight overall design for the fishing rod guide.

[0035] (8) The feature may also be that the frame includes the wire and a sleeve disposed on a portion of the wire, and the second opposing surface has a planar shape portion on the sleeve, and the second opposing surface is disposed on the sleeve.

[0036] In this case, a square sleeve, which is a different component from the wire of the frame, can be arranged to cover the wire. The square sleeve is received and fixed in the outer peripheral groove of the guide ring. In this case, the square sleeve has, for example, a rectangular cross-sectional shape. Therefore, the surface area of ​​the portion of the sleeve received in the outer peripheral groove can be larger, thereby ensuring a larger contact area between the sleeve and the outer peripheral groove. Thus, a larger filling area for adhesive can be ensured between the sleeve and the outer peripheral groove, thereby increasing the fixation strength between the sleeve and the outer peripheral groove and improving their fixing force.

[0037] In addition, by making the sleeve a different part from the wire, thinner wires can be used.

[0038] Furthermore, in this invention, the sleeve can be made of a different material than the wire. For example, by using a material with good adhesion, the fixing force with the guide ring can be improved.

[0039] (9) The feature may also be that at least a portion of the cross section of the sleeve is square.

[0040] In this case, the wires constituting the frame are themselves formed with a square cross-section, so there is no need to use other components to form the second opposing surface. As a result, the frame can be easily manufactured, and the increase in component costs can be suppressed.

[0041] (10) The sleeve may also have a receiving portion for receiving the wires of the frame.

[0042] In this case, the contact area between the sleeve and the wire housed in the housing can be increased.

[0043] The effects of the invention

[0044] The fishing rod guide according to the present invention facilitates the positioning of the frame and guide ring, prevents the reduction of the fixing force of the two, and enables weight reduction. Attached Figure Description

[0051] Hereinafter, embodiments of the fishing rod guide of the present invention will be described with reference to the accompanying drawings. Furthermore, in each drawing, the scale of each component may be appropriately changed as needed to make each component a visually perceptible size.

[0052] like Figures 1 to 3 As shown, the rod guide 1 of this embodiment is a guide component that is fixed to the outer peripheral surface 10a of the rod body 10 of the fishing rod and maintains the guide ring 2 for inserting the fishing line. Multiple rod guides 1 are arranged at predetermined intervals on the outer peripheral surface 10a of the rod body 10 in the rod axis direction.

[0053] The fishing rod guide 1 includes: a guide ring 2 for inserting and guiding the fishing line; and a guide frame 3 fixed to the rod body 10, extending outward in the direction of the rod diameter, and holding the guide ring 2.

[0054] Here, in the fishing rod guide 1 shown in the attached diagram, the axial direction of the rod body 10 is referred to as the front-rear direction X, and the rod tip side (front side) is indicated by the symbol X1, and the rod butt side (rear side) is indicated by the symbol X2. Furthermore, the direction orthogonal to the axial direction of the rod body 10 and passing through the central axis 2C of the guide ring 2 is designated as the vertical direction Z, with the direction away from the rod body 10 designated as the upper side by the symbol Z1, and the direction closer to the rod body 10 designated as the lower side by the symbol Z2. Additionally, the upper side Z1 is sometimes referred to as the front end side, and the lower side Z2 as the base end side. Furthermore, the direction orthogonal to the axial direction of the rod body 10 from a top view observed from the upper side Z1 is designated as the horizontal direction Y. Moreover, the axial direction of the rod body 10 (front-rear direction X) is the direction of the central axis 10C of the rod body 10, and is the length direction of the mounting foot 32 of the guide frame 3 described below; the horizontal direction Y is the direction of the short side (width direction) of the mounting foot 32. In addition, in the following description, the direction of rotation of the guide ring 2 about the central axis 2C when viewed from the central axis 2C direction is defined as the circumferential direction, and the direction orthogonal to the central axis 2C is defined as the radial direction.

[0055] (guide ring)

[0056] The guide ring 2 has an outer peripheral groove 21 and is coaxially held with the frame 30 of the guide holder 3. The outer peripheral groove 21 is located on the outer periphery that is further outward in the rod diameter direction than the central axis 2C of the guide ring 2. That is, the fishing line is directly guided by sliding on the inner peripheral surface 2a of the guide ring 2.

[0057] The guide ring 2 is formed in a circular ring shape, and its inner circumferential guiding surface is formed of a material with low sliding resistance to the fishing line, such as titanium, aluminum, SUS, or ceramic. Furthermore, in this embodiment, the guide ring 2 is provided as a circular ring, but it can also be elliptical or oblong. The guide ring 2 is formed, for example, by stamping a metal sheet into a predetermined shape.

[0058] like Figure 4 As shown, the inner circumferential surface 2a of the guide ring 2 forms a curved surface, which, when viewed in cross-section, points inward ( Figure 2 The guide ring 2 (shown on the central axis 2C side) protrudes and bends in the front-rear direction X. The outer peripheral groove 21 of the guide ring 2 has a concave curved surface 21A (first opposing surface) that is disposed opposite to at least a portion of the frame 30 (hereinafter). The concave curved surface 21A forms a concave shape that is recessed toward the center direction (central axis 2C side) of the guide ring 2.

[0059] The guide ring 2 has: a convex inner peripheral surface 2a, which is curved into an arc shape when viewed in a cross section along the vertical direction Z, protruding from the central axis 2C; and a concave outer peripheral surface (outer peripheral groove 21), which is curved into an arc shape, protruding from the central axis 2C.

[0060] Specifically, the outer peripheral groove 21 of the guide ring 2 has flange portions 21b and 21c. When viewed in cross-section, the bottom 21a of the central portion in the front-rear direction X protrudes radially outward on both sides. Thus, a concave outer peripheral groove 21 is formed between the two flange portions 21b and 21c on the outer peripheral surface of the guide ring 2, covering the entire circumference.

[0061] Between the two flanges 21b and 21c in the outer peripheral groove 21 of the guide ring 2, the frame 30 of the guide bracket 3 is engaged within an angle range of approximately 180 degrees from the central axis 2C to the upper side Z1 throughout the entire circumference of the circular cross section of the guide ring 2.

[0062] (guide frame)

[0063] like Figures 1 to 3 As shown, the guide frame 3 includes: a frame 30, which is composed of annular wires that hold the guide ring 2; a support foot 31, which is fixed to the rod body 10, connected to the frame 30 and supporting it; and a mounting foot 32, which is connected to the support foot 31 and fixed to the outer peripheral surface 10a of the rod body 10.

[0064] The guide bracket 3 is fixed to the outer peripheral surface 10a of the rod body 10 with the frame 30 facing the rod head side (front side X1) relative to the mounting foot 32. At this time, the mounting foot 32 extends in the front-rear direction X.

[0065] The guide frame 3 bends upwards towards Z1 from the front end of the mounting foot 32, and then extends upwards in a straight line towards Z1. The part of the guide frame 3 that bends upwards towards Z1 is the support foot 31. Furthermore, in this embodiment, the support foot 31 stands at a right angle relative to the mounting foot 32, and the central axis 2C of the guide ring 2 is parallel to the central axis 10C of the rod body 10. However, the support foot 31 can also stand at an angle where the central axis 2C of the guide ring 2 is not parallel to the central axis 10C of the rod body 10. For example, the support foot 31 can also be in a forward-leaning posture.

[0066] The support foot 31 is located between the frame 30 and the mounting foot 32, connecting the frame 30 and the mounting foot 32. Figure 1 As shown, the support legs 31 are two-legged structures arranged side by side. The left and right pair of support legs 31 are symmetrical to each other. The left and right pair of support legs 31 extend downward from both ends of the circumference of the frame 30, forming a V-shape when viewed from the front or rear.

[0067] The left and right pair of support legs 31 extend in a straight line along the tangents at both ends of the frame 30 in the circumferential direction, and are in such a state that they gradually approach each other as they move toward the mounting legs 32, that is, they reduce the distance between them, and extend toward the inside of the left and right direction Y, and abut against each other at the lower ends.

[0068] The upper end 31a of the support foot 31 is located on a plane orthogonal to the central axis of the frame 30 (the central axis 2C of the guide ring 2).

[0069] The mounting feet 32 ​​extend in a straight line from the lower end of the support feet 31 toward the rear X2 (the rod tip side) when viewed from above. In this embodiment, the mounting feet 32 ​​are two-leg structures formed by two predetermined length regions at both ends of a single metal wire. That is, the mounting feet 32 ​​are formed by two predetermined length regions at both ends of a single metal wire, configured as a pair of horizontally aligned parallel lines without any gap, each line extending rearward from the lower end 31b of the support feet 31. The pair of horizontally aligned lines are joined together to form an integral unit. The joining method is arbitrary, but welding is preferred.

[0070] Install 32 images of the feet Figure 3 In this way, the line 11 is wound around the outer circumference 10a of the rod body 10.

[0071] The frame 30 is supported by support feet 31 at a position away from the outer peripheral surface 10a of the rod body 10, and holds the guide ring 2 for guiding the fishing line on its inner peripheral surface. The frame 30 is made of metal wire bent into a U-shape, with its two circumferential ends connected to the upper ends 31a of a pair of support feet 31, respectively. The frame 30 holds the guide ring 2 on its inner peripheral surface by engaging with an outer peripheral groove 21 formed on the outer peripheral surface of the guide ring 2.

[0072] The metal wires constituting the frame 30 include, for example, titanium alloys, stainless steel, or aluminum alloys. In particular, from a lightweighting point of view, titanium alloys are preferred. The metal wires have a square cross-sectional shape. In this embodiment, the frame 30 is a solid frame.

[0073] Furthermore, regarding the metal wire of the frame 30, from the viewpoints of balancing lightweight and strength, and easily ensuring the contact area with the guide ring 2, a hollow metal wire, i.e., a wire tube, is preferred. Alternatively, a cavity without internal filler may also be used. The wire diameter (outer diameter) of the metal wire can be, for example, approximately 0.3 to 6 mm.

[0074] like Figure 4 As shown, the frame 30 is internally housed within the outer peripheral groove 21 of the guide ring 2, and is integrally connected to the guide ring 2 via an adhesive 4 filling the space S formed between the frame 30 and the outer peripheral groove 21. In cross-sectional view, the frame 30 is formed into a generally rectangular shape that is longer in the front-rear direction X, and has an inner peripheral surface 30a, an outer peripheral surface 30b, a front surface 30c, and a rear surface 30d. Furthermore, the frame 30 has a substantially uniform cross-sectional shape along its entire length. That is, the inner peripheral surface 30a is provided on the entire half-circumference of the side furthest from the rod body 10. Figure 1and Figure 2 The range of L shown can be set, but it can also be set at any part of the half-circle.

[0075] The inner circumferential surface 30a (second opposing surface) of the frame 30, when inserted into the outer circumferential groove 21 of the guide ring 2, is positioned opposite to the concave curved surface 21A formed in the outer circumferential groove 21. The inner circumferential surface 30a of the frame 30 has a cross-sectional view along the central axis 2C of the guide ring 2 (see reference). Figure 2 The planar shape portion 301 in the front-rear direction X. On both sides (front side X1, rear side X2) of the planar shape portion 301 in the front-rear direction X, inclined surfaces 302 are formed continuously with the front surface 30c and the rear surface 30d, respectively. A portion of the two inclined surfaces 302 of the frame 30 (corner portions 302a and 302b of the inclined surfaces 302) contacts the concave curved surface 21A of the outer peripheral groove 21.

[0076] In this way, the inner circumferential surface 30a of the frame 30 and the concave curved surface 21A of the outer circumferential groove 21 have different shapes. That is, in the fishing rod guide 1, a space S is formed between the concave curved surface 21A of the curved guide ring 2 and the inner circumferential surface 30a of the frame 30, which is formed by three planes (planar shape portion 301, a pair of inclined surfaces 302, 302). This space S is filled with adhesive 4. The guide ring 2 is held in the frame 30 by being fixed to the frame 30 by adhesive 4.

[0077] As an assembly method for fixing the guide ring 2 to the frame 30, adhesive 4 is applied or filled to the concave surface 21A of the outer peripheral groove 21 of the guide ring 2. The outer peripheral groove 21 is then engaged with the inner peripheral surface 30a of the frame 30. At this time, the outer peripheral groove 21 is positioned at the location where the inclined surface 302 of the inner peripheral surface 30a abuts against the concave surface 21A, and after the adhesive 4 hardens, the outer peripheral groove 21 is fixed and assembled to the inner peripheral surface 30a of the frame 30.

[0078] Next, based on the accompanying drawings, the function of the guide 1 for a fishing rod constructed in this way will be explained in detail.

[0079] In this embodiment, such as Figure 4 As shown, the curved concave surface 21A of the outer peripheral groove 21 of the guide ring 2, which is disposed opposite to at least a portion of the frame 30, and the planar inner peripheral surface 30a of the frame 30, which is disposed opposite to the concave surface 21A, have different shapes. Therefore, the surface area of ​​the concave surface 21A and the inner peripheral surface 30a being disposed opposite to each other can be increased. Thus, a larger contact area between the guide ring 2 and the frame 30 can be ensured, thereby improving the fixing force between the two.

[0080] In addition, in this embodiment, it is easy to position the frame 30 and the guide ring 2 by simply arranging the concave curved surface 21A of the guide ring 2 opposite to the inner peripheral surface 30a of the frame 30.

[0081] Furthermore, in this embodiment, it is not necessary to make the cross-sectional shape of the frame 30 consistent with the shape of the outer peripheral groove 21 of the guide ring 2. Therefore, the thickness or cross-sectional shape of the frame 30 can be reduced, thereby achieving weight reduction.

[0082] Furthermore, according to this embodiment, by fixing the frame 30 with its ring contact portion housed within the outer peripheral groove 21 of the guide ring 2, the protruding portion of the frame 30 extending from the outer peripheral groove 21 can be minimized. Therefore, it prevents damage to the frame protruding from the outer peripheral groove, as is the case previously, or the fishing line from becoming tangled in the protruding portion, or seawater accumulation due to seawater adhesion.

[0083] Furthermore, in this embodiment, the concave surface 21A of the guide ring 2 has a concave shape that is recessed toward the center of the guide ring 2, and the inner peripheral surface 30a of the frame 30 has a planar shape along the central axis of the guide ring 2. Therefore, a larger space (area) can be ensured between the guide ring 2 and the frame 30, and the adhesive 4 can be fully filled in this space (area) as in this embodiment, thereby increasing the adhesion strength between the inner peripheral surface 30a and the outer peripheral groove 21 and improving the fixing force between them.

[0084] Furthermore, in this embodiment, sufficient space S (filled area) can be ensured between the inner peripheral surface 30a and the outer peripheral groove 21 of the frame 30. By filling this filled area with adhesive 4, the fixing force between the inner peripheral surface 30a and the outer peripheral groove 21 can be further improved.

[0085] Furthermore, by filling the space S between the frame 30 and the guide ring 2 with adhesive 4, the gap (step) formed between the frame 30 and the guide ring 2 can be eliminated, and seawater will not remain in the step portion as before, thereby suppressing the accumulation of seawater.

[0086] In addition, in this embodiment, at least one of the concave curved surface 21A and the inner circumferential surface 30a is provided in at least a portion of the half-circumference on the side away from the rod body 10. Therefore, the connection area between the frame 30 and the guide ring 2 can be connected intermittently or partially in the circumferential direction. Therefore, compared with the case of connection throughout the entire circumference, the cross-sectional area of ​​the component can be reduced, thereby achieving weight reduction.

[0087] In addition, in this embodiment, the width of the square portion in the frame 30 is equivalent to the width of the slot. Therefore, the wire of the frame 30 can be made thinner than before, thereby achieving a lightweight overall design of the fishing rod guide 1.

[0088] In the fishing rod guide 1 of this embodiment, configured as described above, the frame 30 and the guide ring 2 are easily positioned, which can prevent the fixing force of the two from decreasing and can achieve weight reduction.

[0089] (First variation)

[0090] Figure 5 The fishing rod guide 1A shown in the first modification example has the following structure: the frame 30A has a wire 33 with a circular cross-section and a sleeve 34 that houses a portion of the wire 33. In this first modification example, the wire 33 is a solid wire made by filling a hollow tube with a filler material 331 such as resin, but a hollow tube without filler material 331 can also be used directly. The guide ring 2 in the first modification example has the following structure: it has an outer peripheral groove 21 with the same concave curved surface 21A as in the above embodiment.

[0091] When viewed in cross-section, the sleeve 34 is generally square in shape, having a hollow through-hole 34b (receiving portion) that is longer in the front-rear direction X. The wire 33 is inserted through and received inside the through-hole 34b. That is, the sleeve 34 extends in a U-shape along the wire 33. The inner circumference of the sleeve 34 is disposed in the outer circumferential groove 21 of the guide ring 2, and is integrally connected to the guide ring 2 by an adhesive 4 filling the space S formed between the sleeve 34 and the outer circumferential groove 21.

[0092] Furthermore, in this first variation, the sleeve 34 is provided with a through hole 34b, but it is not limited to a through hole 34b. For example, it may also have a groove that allows the wire 33 to be engaged.

[0093] In addition, in this first modified example, the through hole 34b of the sleeve 34 is hollow, but the wire 33 can also be kept in the through hole 34b by filling the hollow part with a lightweight material such as a foaming agent.

[0094] The sleeve 34 has an inner peripheral wall 34A, an outer peripheral wall 34B, a front wall 34C, and a rear wall 34D. Furthermore, the sleeve 34 has a substantially uniform cross-sectional shape along its entire length. That is, the inner peripheral wall 34A is provided for the entire half-circumference on the side furthest from the rod body 10. Figure 1 and Figure 2 The range of L shown can be set, but it can also be set at any part of the half-circle.

[0095] When the inner peripheral wall 34A of the sleeve 34 is inserted into the outer peripheral groove 21 of the guide ring 2, its inner peripheral surface 34a is positioned opposite to the concave curved surface 21A formed in the outer peripheral groove 21. The inner peripheral surface 34a of the inner peripheral wall 34A has a planar shape portion 341 that is oriented along the central axis 2C of the guide ring 2 when viewed in cross-section. On both sides (front side X1, rear side X2) of the planar shape portion 341 in the front-rear direction X, inclined surfaces 342 are formed, which are continuously arranged with the front wall 34C and the rear wall 34D, respectively. A portion of the two inclined surfaces 342 of the sleeve 34 (corner portions 342a and 342b of the inclined surfaces 342) contacts the concave curved surface 21A of the outer peripheral groove 21.

[0096] In this way, the inner circumferential surface 34a of the sleeve 34 and the concave curved surface 21A of the outer circumferential groove 21 have different shapes. That is, in the fishing rod guide 1A of the first modified example, a space S is formed between the concave curved surface 21A of the curved guide ring 2 and the inner circumferential surface 34a formed by the three planes (planar shape portion 341, a pair of inclined surfaces 342, 342) in the sleeve 34. The space S is filled with adhesive 4. The guide ring 2 is held in the line 33 in a state where it is fixed to the line 33 by the adhesive 4 via the sleeve 34.

[0097] In the above-described first modified example, a square sleeve 34, which is a different component from the wire of the frame 30A, can be set to cover the wire. The square sleeve 34 is received and fixed in the outer peripheral groove 21 of the guide ring 2.

[0098] In this case, the sleeve 34 can be, for example, rectangular in cross-section. Therefore, the surface area of ​​the portion of the sleeve 34 housed within the outer peripheral groove 21 can be larger, thus ensuring a larger contact area between the sleeve 34 and the outer peripheral groove 21. Consequently, a larger filling area for the adhesive 4 can be ensured between the sleeve 34 and the outer peripheral groove 21, thereby increasing the adhesion strength between the sleeve 34 and the outer peripheral groove 21 and improving their fixing force.

[0099] Furthermore, by making the sleeve 34 a component different from the wire, a thinner wire can be used. Moreover, in this first modification, the sleeve 34 can be made of a different material than the wire; for example, by using a material with good adhesion, the fixing force with the guide ring 2 can be improved.

[0100] Furthermore, in this first modified example, at least a portion of the cross-section of the sleeve 34 is formed as a square, thus eliminating the need for other components to form the inner circumferential surface 34a. This allows for easy machining of the frame 30A and helps to suppress increases in component costs.

[0101] In addition, in this modified example, the sleeve 34 has a through hole 34b for receiving the wire of the frame 30A, thus increasing the contact area between the sleeve 34 and the wire received in the through hole 34b.

[0102] (Second variation)

[0103] Figure 6 The fishing rod guide 1B shown in the second modified example is configured such that a planar shape portion 221 is formed on the outer periphery of the guide ring 2A, and an inner peripheral groove 35 (concave shape portion) is provided on the inner periphery of the frame 30B. The guide ring 2A is fixed to the frame 30B by engaging a portion of the outer periphery of the guide ring 2A (planar shape portion 221) with the inner side of the inner peripheral groove 35 of the frame 30B.

[0104] In the second variation, the inner circumferential groove 35 of the frame 30B forms a curved surface that, when viewed in cross-section, curves in the front-rear direction X in a manner that is concave outward in the radial direction (away from the central axis 2C). The inner circumferential groove 35 has a concave curved surface 35A (a second opposing surface) disposed opposite to at least a portion of the guide ring 2A. The concave curved surface 35A constitutes a concave shape portion that is concave on the opposite side (opposite direction) in the radial direction toward the center direction (central axis 2C side) of the guide ring 2A.

[0105] Specifically, the inner peripheral groove 35 of the frame 30B has flange portions 35b and 35c, which, when viewed in cross-section, protrude radially outward from both sides of the bottom 35a of the central portion in the front-rear direction X. Thus, a concave inner peripheral groove 35 is formed between the two flange portions 35b and 35c on the inner peripheral surface of the frame 30B, extending across the entire length of the frame 30B.

[0106] When viewed in cross-section, the guide ring 2A is formed into a solid, approximately square shape that is longer in the front-rear direction X. The outer periphery of the guide ring 2A is disposed in the inner peripheral groove 35 of the frame 30B, and is integrally connected to the guide ring 2A by an adhesive 4 filling the gap S formed between the guide ring 2A and the inner peripheral groove 35.

[0107] The guide ring 2A has an outer peripheral surface 22a, an inner peripheral surface 22b, a front surface 22c, and a rear surface 22d. The inner peripheral surface 22b of the guide ring 2A is curved into an arc shape. The outer peripheral surface 22a (the first opposing surface) of the guide ring 2A, when inserted into the inner peripheral groove 35 of the frame 30B, is positioned opposite to the concave curved surface 35A formed in the inner peripheral groove 35. The outer peripheral surface 22a has a planar shape portion 221 that, when viewed in cross-section, is along the central axis 2C of the guide ring 2A. Inclined surfaces 222, continuously disposed with the front surface 22c and the rear surface 22d, are formed on both sides (front side X1, rear side X2) of the planar shape portion 221 in the front-rear direction X. A portion of the two inclined surfaces 222 of the guide ring 2A (corner portions 222a and 222b of the inclined surfaces 222) contacts the concave curved surface 35A of the inner peripheral groove 35. In the second modified example, adhesive 4 is also filled between the front surface 22c and the rear surface 22d and the inner peripheral groove 35 (concave surface 35A) of the frame 30B.

[0108] In the second modified example of the fishing rod guide 1B, the outer peripheral surface 22a of the guide ring 2A and the concave curved surface 35A of the inner peripheral groove 35 have different shapes. That is, in the second modified example of the fishing rod guide 1B, a space S is formed between the concave curved surface 35A of the curved frame 30B and the outer peripheral surface 22a formed by the three planes (planar shape portion 221, a pair of inclined surfaces 222, 222) in the guide ring 2A. This space S is filled with adhesive 4. The guide ring 2A is held in the frame 30B in a state where it is fixed to the frame 30B by the adhesive 4.

[0109] In the aforementioned second modification, the outer peripheral surface 22a of the outer peripheral groove 21 of the guide ring 2A, which is disposed opposite to at least a portion of the frame 30B, and the concave curved surface 35A of the frame 30B opposite to the outer peripheral surface 22a, have different shapes. Therefore, the opposing surface area of ​​the outer peripheral surface 22a and the concave curved surface 35A can be increased. Thus, a larger contact area between the guide ring 2A and the frame 30B can be ensured, thereby improving the fixing force between them.

[0110] In addition, in this embodiment, it is only necessary to align the outer peripheral surface 22a of the guide ring 2A with the second opposing surface of the frame 30B, so it is easy to position the frame 30B and the guide ring 2A.

[0111] Furthermore, in this embodiment, it is not necessary for the cross-sectional shape of the frame 30B to match the shape of the outer peripheral surface 22a of the guide ring 2A. Therefore, the thickness or cross-sectional shape of the frame 30B can be reduced, thereby achieving weight reduction.

[0112] Furthermore, in the second modification, the outer peripheral surface 22a has a planar shape along the central axis of the guide ring 2A, and the concave surface 35A has a concave shape recessed in the direction opposite to the central direction of the guide ring 2A. Therefore, a larger space S (area) can be ensured between the guide ring 2A and the frame 30B, and the adhesive 4 as in this modification can be fully filled in the space (area), thereby increasing the adhesion strength between the concave surface 35A and the outer peripheral surface 22a and improving the fixing force between them.

[0113] The embodiments of the fishing rod guide of the present invention have been described above, but these embodiments are provided as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in many other ways, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The embodiments or their variations may include, for example, content that can be easily conceived by those skilled in the art, substantially the same content, or content of equal scope.

[0114] For example, in this embodiment, the first opposing surface and the second opposing surface are disposed on any part of the half-circumference on the side away from the rod body 10, but they can also be the entire half-circumference as in the above embodiment, or they can be discontinuous in the circumferential direction.

[0115] In this embodiment, an example of using adhesive 4 to fix the frames 30, 30A, 30B to the guide rings 2, 2A is shown, but it is not limited to adhesive 4. For example, it can also be a riveting fixing method.

[0116] In this embodiment, the protruding front end side of the fishing rod guide is defined as the upper side in the direction away from the rod body 10 in the vertical direction. However, this is the case where the fishing rod guide is installed on the upper side of the rod body of a dual-axis reel. In the case of a spinning reel rod body, the fishing rod guide is installed on the lower side of the rod body 10. Therefore, in this case, the direction away from the rod body of the protruding front end side of the fishing rod guide is the lower side.

[0117] In this embodiment, metal wire is used as the frame, but it can also be a frame formed of metal plates.

[0118] In addition, in this embodiment, the supporting foot 31 and the mounting foot 32 are configured as a two-leg structure, but they can also be a one-leg structure.
