[0024] Hereinafter, embodiments of a fishing rod according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are designated by the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for the sake of convenience.
[0025] Figure 1 is a diagram showing one embodiment of a fishing rod according to the present invention. As shown in the figure, a fishing rod 1 according to one embodiment of the present invention comprises a rod body 2, a reel 6 attached to the rod body 2 via a fishing line guide 9 (also called a reel seat, but referred to as a fishing line guide in this specification) which will be described later, and a fishing line guide 10 attached to the rod body 2. In the embodiment shown in the figure, each of the fishing line guide 9 and the fishing line guide 10 corresponds to an attachment part attached to the outer circumferential surface of the rod body.
[0026] The rod body 2 is constructed by connecting, for example, a butt rod 3, a middle rod 5, and a tip rod 7. These rod bodies are joined, for example, using a straight joint. The butt rod 3, middle rod 5, and tip rod 7 can be joined using a telescoping method, a reverse straight joint method, a spigot joint method, or any other known joining method. The rod body 2 may also be constructed from a single rod body.
[0027] The butt rod 3, middle rod 5, and tip rod 7 are each constructed, for example, as a tubular body made of fiber-reinforced resin. This fiber-reinforced resin tubular body is produced by winding a fiber-reinforced resin prepreg (prepreg sheet) in which reinforcing fibers are impregnated with a matrix resin around a core and then heating and curing the prepreg sheet. The reinforcing fibers contained in the prepreg sheet can be, for example, carbon fiber, glass fiber, or any other known reinforcing fiber. The matrix resin contained in the prepreg sheet can be a thermosetting resin such as epoxy resin. After the prepreg sheet has cured, the core is removed. The outer surface of the tubular body is polished as appropriate. Each rod body may be constructed in a solid shape.
[0028] In the illustrated embodiment, the butt rod 3, middle rod 5, and tip rod 7 are provided with a plurality of line guides 10 (line guides 10A-10D) that guide the fishing line that is let out from the reel 6. More specifically, the butt rod 3 is provided with line guide 10A, the middle rod 5 is provided with line guide 10B, and the tip rod 7 is provided with line guide 10C. A top guide 10D is provided at the tip of the tip rod 7. Details of the line guides 10 will be described later.
[0029] A fishing line guide according to one embodiment of the present invention will be described with reference to Figures 2 to 7. Figure 2(a) is a front view of a fishing line guide 10 according to one embodiment, Figure 2(b) is a side view of the fishing line guide 10 according to one embodiment, and Figure 2(c) is a perspective view of the fishing line guide 10 according to one embodiment. Figure 3 is a diagram illustrating a method for attaching the fixing portion of a fishing line guide according to one embodiment of the present invention to a fishing rod body, and Figure 4 is a diagram illustrating a second leg portion 13 of the fishing line guide 10 according to one embodiment of the present invention. Figure 5 is a diagram illustrating an end face of the fixing portion 1 of a fishing line guide according to one embodiment of the present invention. Figure 6 is a diagram illustrating a protruding portion of a fishing line guide according to one embodiment of the present invention, and Figure 7 is a diagram illustrating a method for fixing the protruding portion of a fishing line guide according to one embodiment of the present invention to a fishing rod body.
[0030] As shown in FIG. 2, a fishing line guide 10 according to one embodiment of the present invention comprises a guide body 11 having a ring holder 9 to which an annular guide ring (not shown) is attached, a first leg 12 extending from the guide body 11, a second leg 13 branching off from the guide body 11 and extending at an angle (angle β in FIG. 2(b)) different from the angle in the extension direction of the first leg 12 (angle α in FIG. 2(b)), and a fixing part 14 formed between and connected to the first leg 12 and the second leg 13 for fixing to the rod body 2 of the fishing rod 1, and a through hole (space or gap) 15 is formed between the first leg 12, the second leg 13, and the fixing part 14. 2, angle α refers to the angle of first leg 12 at the end position of first leg 12, and angle β refers to the angle of second leg 13 at the end position of second leg 13. In the illustrated example, second leg 13 has the same angle (α) as first leg 12 at the position where it branches off from guide body 11, and because second leg 13 is curved in the extension direction, its angle gradually approaches angle (β) and is formed to finally reach angle (β), but this is not limited to the illustrated example and various embodiments are possible.
[0031] According to the fishing line guide 10 of one embodiment of the present invention, it is possible to provide a fishing line guide that is lightweight, does not hinder the bending of the rod body, and can be held to the rod body with sufficient fixing force without coming loose from the fixing point on the surface of the rod body even when a load is applied to the guide.
[0032] The fishing line guide 10 is typically made of, but is not limited to, metal, resin, or fiber-reinforced resin. While metal is typically used as the material for the guide ring, ceramics (e.g., SiC) and other materials may also be used. As shown in FIGS. 1 and 2(b), the fishing line guide 10 is tilted upward from the rear (the butt end of the fishing rod) to the front (the tip end of the fishing rod) of the fishing rod body 2 when attached. That is, when attached to the fishing rod body 2, the fishing line guide 10 assumes a tilted position toward the front of the fishing rod body 2 (toward the tip of the fishing rod 1). The "front-rear direction" refers to the front-rear direction (the extension direction of the fishing rod 1) shown in FIG. 1. This front direction is the direction from the butt end toward the tip of the fishing rod 1 along the rod shaft. The "up-down direction" refers to the direction perpendicular to the front-rear direction, with the upper side relative to the front-rear direction being the up direction and the lower side being the down direction.
[0033] The ring holder 9 has a through hole 9a that passes through the ring holder 9 along the guide central axis. The through hole 9a is defined by an inner peripheral surface 9b of the ring holder 9 and has, for example, a shape that is symmetrical left to right and up to down when viewed from the front. The guide central axis passes through the center of the through hole 9a and extends in the front-to-rear direction.
[0034] Next, an annular guide ring (not shown) is press-fitted into the through-hole 9a of the ring holder 9. The guide central axis passes through the center of the guide ring. This guide ring is formed, for example, from ceramics, metal, alloy, or a composite material thereof. The guide ring may have a base material layer, an inner surface layer formed on the inner peripheral surface of the base material layer, and an outer surface layer formed on the outer peripheral surface of the base material layer. The base material layer is made of an alloy containing, for example, Co, Ni, Cr, Mo, Fe, and inevitable impurities. The base material layer may also contain Mn, Ti, and / or Nb. The inner surface layer and the outer surface layer are made of, for example, chromium carbide (CrC), titanium carbide (TiC), or vanadium carbide (VC). The inner surface layer and the outer surface layer may have a high hardness of approximately 1300 Hv to 3000 Hv on the Vickers hardness scale. Further details are omitted.
[0035] 2, the guide body 11 has a first connecting portion 11a and a second connecting portion 11b, which connect the already-described ring holding portion 9 to a first leg portion 12 and a second leg portion 13, which will be described later, and a space is formed between the bottom of the ring holding portion 9 and the first connecting portion 11a and the second connecting portion 11b. In this way, the weight of these connecting portions can be reduced.
[0036] As shown in Figure 2, in the fishing line guide 10 according to one embodiment of the present invention, the through hole 15 is configured to have a triangular shape when viewed in a direction parallel to the width direction of the guide body 11 (the left-right direction in Figure 2(a)) (viewed from the side in Figure 2(b)). In this way, a truss structure can be formed, resulting in a lightweight and highly rigid guide. Furthermore, the closed fastening portion makes it possible to effectively prevent the guide from slipping out. Here, as mentioned above, because the second leg portion 13 is curved, the through hole 15 does not have a triangular shape in the strict sense, but can be said to have an approximately triangular shape, and in this specification, the term "triangular shape" includes an approximately triangular shape.
[0037] Furthermore, in the fishing line guide 10 according to one embodiment of the present invention, the angle (α) of the extension direction of the first leg 12 differs from the angle of the extension direction of the second leg 13 by a range of 5 to 45 degrees. In this way, it is possible to form a lighter and more rigid guide.
[0038] In addition, in the fishing line guide 10 according to one embodiment of the present invention, the thickness (X) of the ring holder 9 shown in Figure 2(b) is in the range of 1.5 mm to 2.5 mm. In this way, it is possible to prevent a direct impact from being applied to the guide ring.
[0039] In the fishing line guide 10 according to one embodiment of the present invention, the thickness (Y) of the first leg 12 shown in FIG. 2(b) is in the range of 0.5 mm to 1.2 mm. In this way, it is possible to achieve a lighter weight while maintaining the necessary rigidity and strength. In addition, in the fishing line guide 10 according to one embodiment of the present invention, the thickness (Z) of the second leg 13 shown in FIG. 2(b) is in the range of 0.5 mm to 1.2 mm. In this way, it is possible to achieve a lighter weight while maintaining the necessary rigidity and strength.
[0040] Furthermore, in the fishing line guide 10 according to one embodiment of the present invention, the thickness (L) of the fixed portion 14 shown in FIG. 2(b) is in the range of 0.2 mm to 1.0 mm. This allows for weight reduction while maintaining the required strength. Furthermore, depending on the ring size, the length of the fixed portion 14 can be set in the range of 3 mm to 15 mm. This allows for a shorter length than conventional fishing line guides, resulting in a technical feature of less impeding the bending of the fishing rod body. Furthermore, since the line winding area of the fixed portion 14 is not sloped, the line is less likely to slip even with a shorter winding length, and the holding force can be stabilized. Furthermore, the width of the fixed portion 14 (the width in the short direction of the fixed portion 14 (the length viewed in the circumferential direction of the fishing rod body when attached)) may be narrowed at one or more locations. In other words, the fixed portion 14 may have recesses formed at one or more locations. In this way, the line is wound by hooking it into the recesses, thereby further improving the holding force of the fishing line guide.
[0041] In the fishing line guide 10 according to one embodiment of the present invention, the thickness (X) of the ring holding portion 9 is equal to or greater than the thickness (Y) of the first leg portion 12 or the thickness (Z) of the second leg portion 13, and the thickness (L) of the fixing portion 14 is equal to or less than the thickness (Y) of the first leg portion 12 or the thickness (Z) of the second leg portion 13. In this way, it is possible to reduce the weight while maintaining the required strength.
[0042] Next, as shown in Figure 3, in the fishing line guide 10 according to one embodiment of the present invention, the fixing part 14 is attached to the outer surface of the fishing rod body by a line spool (example of Figure 3), a line clip, or a sheet winding. In this way, it is possible to improve the fixing force of the fishing line guide.
[0043] Next, as shown in Figure 4, in the fishing line guide 10 according to one embodiment of the present invention, the second leg 13 is partially detachable (as in Figure 4(a)) or openable (as in Figure 4(b)). In this way, a line or sheet for winding, fastening, or winding a sheet can be easily and reliably inserted into the through-hole 15, so that the fixing part 14 of the fishing line guide 10 can be easily fixed to the fishing rod body 2.
[0044] Next, as shown in Figure 5, in a fishing line guide 10 according to one embodiment of the present invention, one or more recesses (grooves) 18 (in the illustrated example, multiple recesses (grooves)) are formed along the longitudinal direction P of the second surface 17 of the fixing portion 14, on the side opposite to the first surface (end surface) 16 on which the fishing rod body 2 is disposed when the fishing line guide 10 is in use. In this way, it is possible to improve the fixing force of the fishing line guide. Here, when multiple recesses 18 are provided, the spacing between adjacent recesses 18 is set to, for example, 1 mm or more, and the maximum depth of each recess 18 can be, for example, 0.3 mm, but is not limited thereto.
[0045] Next, as shown in Figure 6, in a fishing line guide 10 according to one embodiment of the present invention, fixed portion 14 is provided with a protruding portion 19 that extends from fixed portion 14 and protrudes outward (to the left (in the case of Figure 6) or to the right on the paper surface of Figure 6) beyond second leg portion 13 (in the case of Figure 6) or first leg portion 12. In this way, the line-holding resin is less likely to peel off, and even if it does peel off and whiten, the whitening can be made less visible.
[0046] Next, as shown in Figure 7, in the fishing line guide 10 according to one embodiment of the present invention, the protrusion 19 is attached to the outer surface of the fishing rod body 2 by using a line spool (in the case of Figure 7), a line clip, or a sheet winding. In this way, the line clipping thread absorbs the resin, making it difficult for the resin to peel off, and even if it does peel off and turn white, the whitening can be made less visible.
[0047] Next, as shown in Figure 8, in a fishing line guide 10 according to another embodiment of the present invention, the second leg 13 may be formed on the opposite side of the first leg 12 from the side on which the second leg 13 shown in Figure 2 is provided. In this case, the angle (θ) of the second leg 13 shown in Figure 8 is set to a range of 90 to 150 degrees. In this way, the two fixing points required in the current two-leg guide can be reduced to one, thereby shortening the installation time. The other configurations are the same as those already described, so further details will be omitted.
[0048] Next, as shown in FIGS. 1 and 2 (or FIG. 8), a fishing rod 1 according to one embodiment of the present invention is configured to include any one of the fishing line guides 10 described above and a rod body 2.
[0049] According to a fishing rod according to one embodiment of the present invention, it is possible to provide a fishing rod equipped with a fishing line guide that is lightweight, does not hinder the bending of the rod body, and can be held to the rod body with sufficient fixing force without coming loose from the fixed point on the surface of the rod body even when a load is applied to the guide.
[0050] The dimensions, materials, and arrangement of each component described in this specification are not limited to those explicitly described in the embodiments, and each component can be modified to have any dimensions, materials, and arrangement that can be included in the scope of the present invention. Furthermore, components not explicitly described in this specification can be added to the described embodiments, and some of the components described in each embodiment can be omitted.
