Description

[Technical Field]

[0001] The present invention relates to various types of assembly parts fixed to a rod shaft, for example, a fishing rod to which a fishing line guide for guiding a fishing line is fixed, and to a method for fixing the assembly parts. [Background technology]

[0002] Conventionally, fishing rods equipped with reels have multiple line guides fixed along the axial direction to guide the fishing line as it is unwound from the reel. When a large tension acts on the fishing line, such as when a fish is hooked, the line guides can become loose or rattle relative to the rod shaft. For this reason, Patent Document 1 discloses the provision of a fixing aid for fixing the line guides to the outer periphery of the rod shaft.

[0003] The fixing aid is made of synthetic resin such as polyethylene or polypropylene, or fiber-reinforced resin, and has recesses or slits into which the legs of the fishing line guide fit. With the legs fitted into the recesses or slits, the fixing aid is fixed by wrapping the attachment line around the outer periphery of the rod. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-132558 Summary of the Invention [Problem to be solved by the invention]

[0005] The fishing rod disclosed in the above-mentioned Patent Document 1 is configured to have a separate fixing aid attached to the outer periphery of the rod shaft, which increases the number of work steps and requires alignment, making assembly work less efficient. Also, since a separate fixing aid must be attached to the rod shaft, the weight increases.

[0006] An object of the present invention is to provide a fishing rod in which the work of fixing assembled parts is easy and the weight increase is suppressed, and a fixing method that makes it easy to fix assembled parts to a fishing rod. [Means for solving the problem]

[0007] The present invention is a fishing rod having a resin protrusion printed on the surface of the rod shaft, characterized in that the resin protrusion has a certain height from the surface of the rod shaft so that the outer edge of the fixing part of the assembly part abuts against it.

[0008] The fishing rod described above is positioned by abutting the outer edge of the fixing portion of the attached part, such as the fishing line guide, against the resin protrusion formed by printing on the surface of the rod shaft. In this state, the attached part is fixed using a reel, synthetic resin, carbon cloth, etc., as in the conventional fixing method. Therefore, the fixing work of the attached part can be performed without providing a separate fixing auxiliary tool to the rod shaft, and the fixing work is easy and the weight increase is suppressed.

[0009] The present invention also provides a fixing method that facilitates the work of fixing an assembly part to a fishing rod, and this fixing method is characterized by forming a resin convex portion having a certain height from the surface of the rod by inkjet printing on the surface of the rod so that the outer edge of the fixing part of the assembly part can abut against it, positioning the outer edge of the fixing part of the assembly part by abutting against the resin convex portion, and fixing the fixing part of the assembly part to the surface of the rod with a fixing member.

[0010] As described above, the outer edge of the fixing part of the assembly part is configured to abut against the resin protrusion formed on the surface of the rod by inkjet printing, which makes it easy to form the resin protrusion and also allows for accurate control of the formation position, making alignment easy. In addition, since there is no need for a fixing auxiliary tool as in the past, it is possible to suppress weight increase. [Effects of the Invention]

[0011] According to the present invention, a fishing rod in which the work of fixing assembly parts is easy and an increase in weight is suppressed, and a fixing method in which the work of fixing assembly parts to a fishing rod is easy, can be obtained. [Brief explanation of the drawings]

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fishing rod and an embodiment of a method for fixing assembled parts according to the present invention will be specifically described with reference to the accompanying drawings. In the following embodiments, a fishing line guide is exemplified as an assembly part fixed to a fishing rod, but assembly parts include a hook keeper that secures the fishing line of the tackle, a plate-shaped reel seat that secures the reel, a fishing line introduction guide that guides the fishing line into the rod shaft, etc., and are not limited to fishing line guides.

[0014] 1 shows an embodiment of a fishing rod according to the present invention. The fishing rod 1 of this embodiment comprises a butt rod 3, a middle rod 4, and a tip rod 5, which are joined together using a straight joint. A reel seat 7 is provided on the butt rod 3, and fishing line guides that guide the fishing line being let out from a reel R attached to the reel seat 7 are fixed in appropriate positions on the butt rod 3, middle rod 4, and tip rod 5.

[0015] The fishing line guides of the fishing rod of this embodiment are fixed at one location (line guide 3A) at the tip of the butt rod 3, two locations (line guides 4A and 4B) at the tip and middle of the middle rod 4, and multiple locations (line guides 5A-5F) along the axial direction of the tip rod 5, with a top guide 5T fixed to the tip of the tip rod 5. The number and configuration of the line guides are not limited and can be modified as appropriate depending on the joint type, purpose, length, etc. of the fishing rod. For example, if the fishing rod is configured as a telescopic rod, the line guides 4A, 5A-5F arranged in the middle regions of each rod may be configured as floating guides.

[0016] The butt rod 3, middle rod 4, and tip rod 5 are each formed, for example, from a tubular body made of fiber-reinforced resin, and are formed into a tubular shape of predetermined dimensions according to a standard method, such as by winding a fiber-reinforced resin prepreg (prepreg sheet) made of reinforcing fibers (mainly carbon fiber or glass fiber) impregnated with a thermosetting synthetic resin such as epoxy resin around a core, heating the core, and then removing the core. In this case, the tip rod 5 can be formed in various ways, such as by being solid, or by joining a tubular body to a solid core material (for example, a superelastic alloy wire or a superelastic resin material). The middle rod 4 may be omitted, or two or more rods may be joined together. The configuration of the prepreg sheet, the number of windings (layers), the surface treatment method of the outer surface, etc. are well known, so detailed explanations will be omitted.

[0017] 2 is a perspective view of the fishing line guide 3A fixed to the butt rod 3. The fishing line guide 3A is positioned and fixed to the surface of the rod, which has been surface-treated. Note that the other fishing line guides fixed to the rod have the same structure, so the following explanation will focus on the fixing structure of the fishing line guide 3A.

[0018] 2, the fishing line guide 3A of this embodiment is fixed to the surface of the butt rod 3 and includes a fixed part 10 extending in the axial direction of the butt rod, and a plate-like leg part 11 that is formed on one end of the fixed part 10 and stands up at an angle. A circular opening is formed at the tip of the leg part 11, and an annular guide ring 12, through which the fishing line slides, is secured in this opening.

[0019] There is no limitation on the material that constitutes the fixed portion 10 and the leg portion 11, and they can be integrally formed from, for example, a metal material such as aluminum or a fiber-reinforced resin material. The guide ring 12 is formed from a hard material such as titanium, SUS, ceramics, etc., and its shape is not limited, and it can be an elliptical shape other than the circular shape shown in Fig. 2. Therefore, the shape of the opening of the leg portion 11 can be appropriately changed depending on the shape of the guide ring.

[0020] The fixed portion 10 of the fishing line guide 3A is a portion that is fixed in a positioned state on the surface of the butt rod 3, and in this embodiment, the fixed portion 10 is configured in an approximately rectangular shape with curved surfaces on the front and rear outer edges, and has a predetermined thickness (height H; see Figure 4).

[0021] A resin protrusion 20 is provided on the surface of the butt rod 3 by printing. This resin protrusion 20 is positioned by the outer edge 10a of the fixing portion 10 abutting against it. When positioning the resin protrusion 20, it is preferable that the entire outer edge 10a abuts so that the fixing portion 10 does not shift or wobble. The resin protrusion 20 of this embodiment is formed in an annular shape so that the fixing portion 10 of the fishing line guide 3A fits into it (the entire outer edge 10a of the fixing portion abuts), and is configured so that the fixing portion 10 can be fitted into a recess 20a surrounded by the annular wall.

[0022] As shown in Figures 2(a), 4(a) and 5, the annular resin protrusion 20 has a certain height H1 from the surface of the butt rod so that when the fixing portion 10 of the fishing line guide 3A is fitted into the recess 20a, the entire outer edge 10a abuts against it, thereby restricting circumferential and axial rattles.

[0023] The height H1 of the resin protrusion 20 is preferably equal to or less than the thickness (height) H of the fixing part 10 (H1≦H), which prevents a gap from occurring between the wound thread and the surface of the fixing part 10. Furthermore, since the diameter of the thread wound when positioning and fixing the fixing part 10 is about 0.2 mm, the winding operation can be easily performed by making the height H1 of the resin protrusion 20 0.2 mm or more (higher than the diameter of the thread to be wound).

[0024] The resin protrusions 20 are formed by printing after the base rod is surface-treated. Various printing methods (screen printing, offset printing, etc.) can be used for printing, but inkjet printing using an inkjet printer (not shown) is preferred. When printing by inkjet printing, both ends of the base rod 3 are chucked, and the head of the inkjet printer is scanned along the axial direction while rotating the base rod 3, thereby accurately forming the resin protrusions 20.

[0025] Furthermore, since inkjet printing makes it possible to precisely control the amount, density, and position of the ink applied, it is possible to simultaneously print multiple annular resin protrusions 20 spaced apart in the axial direction, such as the middle rod 4 and tip rod 5 shown in Figure 1, at precise positions.

[0026] The resin material (ink) used in the inkjet printing is not particularly limited in material or color as long as it can stably form the resin protrusions 20. For example, a colorant such as a pigment or dye may be mixed into a transparent or translucent synthetic resin such as epoxy or urethane, and a curing agent may be added to form the resin protrusions 20, or the colorant may be mixed into a UV-curable synthetic resin. Furthermore, printing may be performed using a thermosetting, solvent-drying, or two-component reactive synthetic resin.

[0027] For example, by forming UV-curable resin material (ink) into droplets using multiple spray nozzles and controlling them to overlap in the form of dots (increasing or decreasing the amount of dots), or by controlling the spraying while overlapping when moving the head back and forth along the axial direction, the thickness can be adjusted in the axial direction, and the resin protrusions 20 with a height H1 of 0.2 mm or more as described above can be easily formed with high precision. In addition, it is preferable that the resin protrusion 20 be formed in a color different from that of the surface of the butt rod 3 (by mixing a coloring agent such as a pigment into the resin to be applied) so that it can be easily identified when fixing the fishing line guide 3A.

[0028] In this embodiment, a base resin layer 25 is provided between the fixed portion 10 of the fishing line guide and the surface of the butt rod 3. The base resin layer 25 is provided on the surface (surface of the rod) within the recess 20a of the resin protrusion 20, and in this embodiment, is integrally formed with the resin protrusion 20 by inkjet printing when forming the resin protrusion 20.

[0029] By providing the base resin layer 25, when the fixing portion 10 of the fishing line guide is fitted into the recess 20a of the annular resin protrusion 20, it is possible to prevent scratches on the surface of the butt rod 3 and suppress rattle of the fixed fishing line guide. Furthermore, the presence of the base resin layer 25 makes it possible to improve strength against bending. The thickness of the base resin layer 25 is sufficient if it is thick enough to allow the outer edge 10a of the fixing portion 10 to be restricted by the resin protrusion 20 when the fixing portion 10 is fitted into the recess 20a, as shown in Figure 5.

[0030] It is also preferable that the resin protrusion 20 has an inclined surface 20b that gradually becomes thinner outward from the outer edge 10a of the fixing portion 10 of the fishing line guide. By forming the inclined surface 20b in this manner, when winding the fixing thread 30 (see Figures 2(b) and 4(b)), there is no step between the surface of the fixing part 10, making the fixing work easier and preventing the appearance from being degraded.

[0031] Next, a method for fixing the above-mentioned fishing line guide 3A to the surface of the butt rod 3 will be described. First, a resin protrusion 20 having a certain height H1 (0.2 mm or more) from the surface of the butt rod 3 is printed by inkjet printing on the surface of the butt rod 3 so that the outer edge 10a of the fixing part 10 of the fishing line guide will abut against it. Since the height of the resin protrusion 20 is 0.2 mm or more, the formation position of the resin protrusion can be determined.

[0032] As described above, the resin protrusion 20 is formed by an annular wall, and when the fixing portion 10 of the fishing line guide 3A is fitted into the recess 20a, the entire outer edge 10a of the fixing portion abuts, positioning the fishing line guide 3A. Because the resin protrusion 20 is formed by inkjet printing, the printing position (the position where the fishing line guide is fixed) can be accurately and easily positioned, and the fixing portion 10 is fitted in place, eliminating the need for a temporary fixing of the fishing line guide. Furthermore, because the base resin layer 25 is provided in the recess 20a by inkjet printing together with the resin protrusion 20, scratches on the surface of the butt rod are prevented, and rattle of the fishing line guide can be suppressed.

[0033] In this state, the fixed portion 10 of the fishing line guide is fixed to the surface of the butt rod 3 by winding the line 30, which is the fixing member. As described above, when winding the line 30, the inclined surface 20b is formed around the resin protrusion 20, so when winding the line 30, the step between the fixed portion 10 and the butt rod 3 is eliminated, making the fixing work (line winding work) easy. In addition, because the fixing position of the resin protrusion 20 is determined in advance by inkjet printing, there is no variation in the fixing position depending on the worker.

[0034] Then, with the thread 30 wound around it, synthetic resin is applied by brushing or the like to stabilize the fixed state. When fixing the fishing line guide 3A, in addition to using the line spool as a fixing member and applying synthetic resin as described above, a method of wrapping a carbon cloth as a fixing member around the fixing portion 10 and then hardening the resin may also be used. Such a fixing member makes the fixing work easier.

[0035] In this embodiment, there is no need to attach a separate fixing aid when fixing the fishing line guide, which helps prevent weight gain. Furthermore, the fixing portion 10 is placed in the gap (recess 20a) formed by the printed resin protrusions 20, and the synthetic resin brushed on during fixing is not filled in, which helps prevent weight gain. Furthermore, even if the thickness of the fixing rod or the shape of the guide fixing portion changes, this can be easily accommodated by simply changing the printing area, making it possible to easily form a shape that matches the curvature of the curved surface of the rod.

[0036] It is preferable that the resin protrusions 20 described above are printed so that the amount of constituent resin used decreases as you move toward the tip of the butt rod 3, middle rod 4, and tip rod 5. In this way, by reducing the weight of the rod on the tip side (the tip side of the rod), it is possible to improve flexibility. In this case, the amount of resin used to constitute the resin protrusions 20 needs to be equal to or less than the amount used in the resin protrusions on the tip side.

[0037] The shape of the resin protrusion 20 can be appropriately modified to match the shape (shape of the outer edge 10a) of the fixing part 10. For example, it can be appropriately formed to match the position where the outer edge 10a abuts, as shown in Figures 6(a) to 6(d).

[0038] As shown in the embodiment of Fig. 6(a), the base resin layer may not be provided. Also, as shown in the embodiment of Fig. 6(b), the resin protrusion 20A may be configured to abut only against the rear side of the outer edge 10a of the fixed part 10, or as shown in the embodiment of Fig. 6(c), the resin protrusion 20A may be formed in separate parts (resin protrusions 20B) without being annular, and may abut only against the front and rear ends of the outer edge 10a of the fixed part 10. Furthermore, as shown in the embodiment of Fig. 6(d), the base resin layer 25A may be provided in the configuration of the embodiment shown in Fig. 6(b).

[0039] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways. For example, in the configuration of the fishing line guide described above, the fixed part 10 is a one-leg guide, but it may be configured as a two-leg guide, and the leg part 11 can be modified as appropriate, for example, by being a frame shape with an opening instead of being a plate shape.

[0040] Furthermore, a fishing rod may be configured to have different types of fishing line guides attached, and the shape of the resin protrusion 20 may be different within a single fishing rod. Furthermore, the fixing method described above does not need to be applied to all rod shafts, and may be arranged on only some of the fishing line guide portions of the fishing rod.

[0041] The shape of the resin protrusion 20A can be modified as needed as long as it can be fitted with a fixing portion to prevent axial and / or circumferential rattle. Furthermore, the present invention can be applied to a variety of fishing rods, including single rods, telescopic rods, and spigot jointed rods, as long as they have a fixed fishing line guide.
