Summary of the Invention

Problems to be Solved by the Invention

[0004] When fixing the grip to the rod blank, in order to make the grip thick until it has approximately the same outer diameter as the reel seat, the mass tends to increase. In order to achieve weight reduction, materials such as cork can be used, but there are problems that the workability is poor and it is difficult to widen the design range. Also, when the rod blank is relatively thin, if trying to increase the adhesion area with the grip, the adhesion surface has to be extended in the axial length direction, resulting in a low degree of design freedom.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a fishing rod capable of improving the degree of design freedom and achieving weight reduction.

Means for Solving the Problems

[0006] To solve the aforementioned problems, the present invention provides a rod, a pair of fixed and movable hoods into which the reel legs of a reel are inserted, a reel seat through which the rod is inserted, and an attachment to the end of the reel seat. tube The assembly comprises a cylindrical body and the reel seat Adhering to the outer surface of the hood Attached It comprises a main body and a hollow extension that is continuous with the main body and extends to the vicinity of the rod, with the diameter decreasing as it moves away from the reel seat, and the extension is spaced apart from the rod. It is characterized by being present.

[0007] According to the present invention, a cylindrical body can be used as a grip. Since the cylindrical body is cylindrical and hollow inside, it can be made lighter. Furthermore, because the cylindrical body is attached to the end of the reel seat, which has a larger diameter than the rod shaft, the contact area with the cylindrical body can be increased compared to attaching it to the rod shaft. This reduces the limitations during attachment and increases the degree of design freedom. Furthermore, the reduced diameter of the extended portion of the cylindrical body improves grip. The axial length can also be shortened, allowing for miniaturization. Additionally, the cylindrical body can be easily fixed to the end of the reel seat by adhesive. Moreover, damage to the cylindrical body due to the bending of the rod shaft can be prevented.

[0009] Furthermore, it is preferable that the cylindrical body is made of metal. According to the present invention, the strength of the cylindrical body can be increased, and because it has higher moldability compared to EVA, urethane, cork, etc., steps and gaps between components can be reduced or eliminated.

[0012] Furthermore, the reel seat is provided with a central portion and ends at the ends of the central portion, and it is preferable that a stepped surface is formed by the ends of the reel seat having a smaller diameter than the central portion, and that the cylindrical body is attached to the stepped surface so that the outer circumferential surface of the main body of the cylindrical body and the outer circumferential surface of the central portion of the reel seat are flush. According to the present invention, gripping ability can be further improved.

[0013] Furthermore, it is preferable that the extended portion has an opening that opens to the side. According to the present invention, grip comfort can be further improved, and the design can be enhanced. [Effects of the Invention]

[0014] According to the fishing rod of the present invention, it is possible to improve the degree of freedom in design, improve the grip, and reduce the weight.

Mode for Carrying Out the Invention

[0016] <First Embodiment> Hereinafter, referring to the attached drawings, a first embodiment of the fishing rod according to the present invention will be described. In the description of the drawings, the same elements are denoted by the same reference numerals, and duplicate descriptions will be omitted as appropriate. In the following description, "front and rear" and "up and down" follow the arrows in FIGS. 1, 2, and 5. This direction is used for convenience of explanation and does not limit the direction of the present invention.

[0017] As shown in FIG. 1, the fishing rod 1 includes a rod shaft 2, a reel seat 3, a cylindrical body 4, a rear grip 5, and an end grip 7. The fishing rod 1 is configured such that the rod shaft 2 is inserted through these members in the order of the cylindrical body 4, the reel seat 3, the rear grip 5, and the end grip 7 from the tip side of the rod.

[0018] The rod 2 is a cylindrical member made of resin or wood that serves as the body of the fishing rod 1. The rod 2 may be composed of a single piece or may have a joint structure composed of multiple pieces. The reel seat 3 is a cylindrical member to which the reel leg portion R1 of the fishing reel is detachably fixed. The material of the reel seat 3 is not particularly limited, but in this embodiment, it is formed of resin in consideration of weight reduction. The rod 2 is inserted through the hollow portion inside the reel seat 3. As shown in FIG. 5, the reel seat 3 is fixed to the rod 2 by adhesion via a spacer 9.

[0019] As shown in FIG. 2, the reel seat 3 includes a central portion 31, a front end portion (end portion) 32, and a rear end portion (end portion) 33. The central portion 31 is a portion that constitutes the axial center of the reel seat 3 and has a hollow interior. A flat mounting surface 51 is formed on the upper surface of the central portion 31. The mounting surface 51 is the portion where the central portion of the reel leg portion R1 is mounted.

[0020] The front end portion 32 is a portion that constitutes the front end of the reel seat 3. As shown in FIG. 5, the front end portion 32 generally has a cylindrical shape and is solid. The front end portion 32 includes a large diameter portion 34 and a small diameter portion 35. The large diameter portion 34 is a portion continuous with the central portion 31. The outer diameter of the outer peripheral surface 34a of the large diameter portion 34 is slightly smaller than the outer diameter of the outer peripheral surface 31a of the central portion 31. A stepped surface 37 perpendicular to each other is formed between the outer peripheral surface 34a and the outer peripheral surface 31a.

[0021] The small diameter portion 35 is a portion continuous with the front side of the large diameter portion 34. The outer peripheral surface 35a of the small diameter portion 35 is slightly smaller than the outer peripheral surface 34a of the large diameter portion 34 (see the upper part in FIG. 5). An inclined stepped surface 38 is formed between the large diameter portion 34 and the small diameter portion 35. A molding groove 53 that is formed during molding and extends in the axial direction is formed at the lower part of the small diameter portion 35.

[0022] A fixed hood (a fixed hood) 36 is formed on the upper part of the front end portion 32, cut out from the large diameter portion 34 to the small diameter portion 35. The fixed hood 36 is a hole that opens to the rear, and is the part into which the front end of the reel leg portion R1 is inserted. The fixed hood 36 is provided with a flat mounting surface 52. The mounting surface 52 is formed at approximately the same height as the mounting surface 51 of the central portion 31. The mounting surface 52 is the part on which the front end of the reel leg portion R1 is mounted.

[0023] The rear end portion 33 is the part that constitutes the rear end of the reel seat 3, as shown in Figures 1 and 2. The rear end portion 33 is generally cylindrical and hollow. On the outer circumferential surface of the rear of the rear end portion 33, Male screw A structure has been formed, Female thread The operating cylinder 10 is screwed into the operating cylinder 10. The front end of the operating cylinder 10 is rotatably engaged with the movable hood (movable hood) 6. In addition, a rear grip 5 is provided on the outer circumferential surface of the operating cylinder 10, extending in the circumferential and axial directions. The rear grip 5 is made of a flexible material such as natural cork, artificial cork, or the foamed resin EVA (ethylene vinyl acetate copolymer).

[0024] The movable hood 6 is a cylindrical member that is inserted into the rear end portion 33 and has a hole at its upper part that opens forward. The movable hood 6 is formed to be movable in the front-rear direction relative to the rear end portion 33. A flat mounting surface 54 is provided on the part of the rear end portion 33 that corresponds to the movable hood 6. The mounting surface 54 is formed at approximately the same height as the mounting surface 51 of the central portion 31. The mounting surface 54 is the part on which the rear end of the reel leg portion R1 is placed. A ring member 60 is attached to the outer circumferential surface of the movable hood 6. The ring member 60 is decorated or has bumps and grooves to improve grip. The ring member 60 may be omitted.

[0025] When the rear grip 5 is rotated forward or backward around axis C, the operating cylinder 10 moves in the front-to-back direction due to its screw engagement. Consequently, the movable hood 6 also moves in the front-to-back direction, allowing the reel leg R1 to be fixed or released. As shown in Figures 4 and 5, the cylindrical body 4 comprises a main body portion 41 and an extension portion 42. The material of the cylindrical body 4 is not particularly limited, but it is formed from, for example, metal, resin (including fiber-reinforced resins such as carbon fiber resin and glass fiber resin), etc. The cylindrical body 4 has a grip function for the user to hold. The main body portion 41 is cylindrical and hollow. The outer circumferential surface 41a of the main body portion 41 is decorated or has bumps or grooves to improve grip. The outer circumferential surface 41a may also be a flat surface.

[0026] The inner circumferential surface 41b of the main body portion 41 has a large-diameter inner circumferential surface 41b1, a small-diameter inner circumferential surface 41b2, and an inclined inner circumferential surface 41b3. The large-diameter inner circumferential surface 41b1 is slightly larger in diameter than the small-diameter inner circumferential surface 41b2. The inclined inner circumferential surface 41b3 is an inclined surface between the large-diameter inner circumferential surface 41b1 and the small-diameter inner circumferential surface 41b2. The large-diameter inner circumferential surface 41b1 is in surface contact with the outer circumferential surface 34a of the large-diameter portion 34. The small-diameter inner circumferential surface 41b2 is in surface contact with the outer circumferential surface 35a of the small-diameter portion 35. The inclined inner circumferential surface 41b3 is in surface contact with the stepped surface 38.

[0027] As described above, the front end portion 32 is fitted inside the main body portion 41. The end face 41c of the main body portion 41 abuts against the stepped surface 37. The front end portion 32 and the main body portion 41 may be attached by fitting, press-fitting, screwing, etc., but in this embodiment they are fixed by adhesive bonding.

[0028] The extension portion 42 is continuous with the front end of the main body portion 41 and extends in a direction away from the reel seat 3. The extension portion 42 decreases in diameter as it moves away from the reel seat 3, approaching the rod 2. The rod 2 is inserted through an insertion hole 44 formed at the front end of the extension portion 42. The rod 2 is configured so as not to come into contact with the extension portion 42. In other words, the inner diameter of the insertion hole 44 is larger than the outer diameter of the rod 2. Multiple openings 43 that open to the side are formed in the extension portion 42. The shape and number of openings 43 can be set as appropriate.

[0029] A decorative ring 8 made of resin or metal is provided inside the extension portion 42. The decorative ring 8 comprises a flange portion 8a and a rising portion 8b. The flange portion 8a is plate-shaped and ring-shaped. The flange portion 8a is bonded to the end face of the front end portion 32 with adhesive. The rising portion 8b is the part that rises forward from the flange portion 8a. The rising portion 8b decreases in diameter as it approaches the front. The rising portion 8b may be in contact with the rod 2 as in this embodiment, or it may be spaced apart.

[0030] According to the embodiment described above, the cylindrical body 4 can be used as a grip. Since the cylindrical body 4 is cylindrical and hollow inside, it can be made lighter. In addition, since the extended portion 42 of the cylindrical body 4 has a reduced diameter, the gripping ability can be improved. Conventionally, when the outer diameter of the rod is relatively small, as in this embodiment (for example, around 3 to 10 mm), in order to attach a grip or the like, it is necessary to increase the contact length in the axial direction C to secure the contact area, which limits the design freedom.

[0031] In this embodiment, since the cylindrical body 4 is attached to the front end 32 of the reel seat 3, which has a larger diameter than the rod 2, the contact area with the cylindrical body 4 can be increased compared to attaching it to the rod 2. In other words, because the outer diameter of the front end 32 is larger, the contact length in the axial direction C can be shorter. This reduces the restrictions during installation and increases the degree of design freedom.

[0032] Furthermore, according to this embodiment, the strength of the cylindrical body 4 can be increased, and because it has higher moldability compared to EVA, urethane, cork, etc., steps and gaps between members can be reduced or eliminated. More specifically, the gap and step between the outer surface 41a of the cylindrical body 4 and the outer surface 31a of the central part 31 can be reduced or eliminated.

[0033] Furthermore, according to this embodiment, the main body portion 41 is bonded to the outer circumference of the fixed hood 36. This allows for a shorter axial length and miniaturization. Also, the cylindrical body 4 can be easily fixed to the front end portion 32 of the reel seat 3 by bonding. In addition, according to this embodiment, the extended portion 42 is spaced apart from the rod 2. This prevents the cylindrical body 4 from being damaged by the bending of the rod 2.

[0034] Furthermore, according to this embodiment, the outer circumferential surface 41a of the main body portion 41 of the cylindrical body 4 and the outer circumferential surface 31a of the central portion 31 of the reel seat 3 are flush or approximately flush. This further enhances the user's grip. Furthermore, according to this embodiment, the extended portion 42 has an opening 43 that opens to the side. This improves grip and enhances the design. Also, because the interior is visible through the opening 43, a decorative ring 8 can be provided to create a three-dimensional design. In addition, the decorative ring 8 is in contact with the rod 2 and covers the front end of the front portion 32, thus preventing water and foreign matter from entering the inside of the reel seat 3.

[0035] Furthermore, since the inner circumferential surface of the cylindrical body 4 is provided with a large-diameter inner circumferential surface 41b1 and an inclined inner circumferential surface 41b3, it is easier to insert the cylindrical body 4 into the front end portion 32. After insertion, the outer circumferential surface of the front end portion 32 and the inner circumferential surface of the cylindrical body 4 make surface contact along the axial direction C, thereby increasing the mounting strength.

[0036] <Second Embodiment> Next, a fishing rod according to the second embodiment of the present invention will be described. As shown in Figure 6, the second embodiment differs from the first embodiment in that a movable hood 6 is provided at the front end 32 and a fixed hood 36 is formed on the upper part of the rear end 33. In other words, while the first embodiment was an up-lock type, the second embodiment is a down-lock type (the same applies to the third and fourth embodiments). Also, the cylindrical body 4A differs from the first embodiment in that the outer diameter of the extended portion 42A is constant. The fishing rod 1A according to the second embodiment will be described focusing on the differences from the first embodiment.

[0037] As shown in Figure 6, the fishing rod 1A comprises a rod shaft 2, a reel seat 3, a cylindrical body 4A, and a front grip 5A. The cylindrical body 4A is the grip portion and comprises a cylindrical, hollow main body 41A and an extended portion 42A. The outer diameter of the main body 41A is constant along the axial direction. The cylindrical body 4A is attached to the rear end 33 of the reel seat 3 by fitting the rear end 33 into the interior of the cylindrical body 4A. In other words, the main body 41A is attached to the outside of the fixed hood 36.

[0038] The extension portion 42A is continuous with the main body portion 41A and extends rearward. The extension portion 42A is cylindrical and has a constant outer diameter. The extension portion 42A itself does not come into contact with the rod 2. A cover member 61 is provided at the rear end of the extension portion 42A to cover the rear end. The cover member 61 may be omitted.

[0039] On the outer circumferential surface of the front part of the front end 32, Male screw A structure has been formed, Female thread The operating cylinder 10 is screwed into the movable hood 6. The rear end of the operating cylinder 10 is rotatably engaged with the movable hood 6. In addition, a front grip 5A is provided on the outer circumferential surface of the operating cylinder 10, extending in the circumferential and axial directions. The front grip 5A is made of a flexible material such as natural cork, artificial cork, or the foamed resin EVA (ethylene vinyl acetate copolymer).

[0040] The fishing rod 1A described above can achieve substantially the same effects as the first embodiment. In other words, the cylindrical body 4A may be attached to the rear end of the reel seat 3. Furthermore, since the cylindrical body 4A is attached to the rear end 33 of the reel seat 3, which has a larger diameter than the rod shaft 2, the contact area with the cylindrical body 4A can be increased compared to attaching it to the rod shaft 2. In other words, because the outer diameter of the rear end 33 is larger, the contact length in the axial direction C can be shorter. This reduces the restrictions during attachment and increases the degree of design freedom.

[0041] <Third Embodiment> Next, a fishing rod according to the third embodiment of the present invention will be described. As shown in Figure 7, the shape of the cylindrical body 4B in the third embodiment differs from that of the second embodiment. The fishing rod 1B according to the third embodiment will be described focusing on the differences from the second embodiment.

[0042] As shown in Figure 7, the cylindrical body 4B comprises a main body portion 41B, an extension portion 42B, and an opening 43B. The main body portion 41B is cylindrical and hollow. The extension portion 42B is continuous with the rear end of the main body portion 41B and widens in diameter towards the rear. The extension portion 42B itself does not come into contact with the rod 2. The opening 43B is a hole that opens laterally in the extension portion 42B. A cover member 61 is provided at the rear end of the extension portion 42B to cover the rear end. The cover member 61 may be omitted.

[0043] The fishing rod 1B described above can also achieve substantially the same effects as the first embodiment. That is, the cylindrical body 4B may be attached to the rear end of the reel seat 3, or the extended portion 42B may be widened towards the rear. This allows for variations in the grip configuration.

[0044] <Fourth Embodiment> Next, a fishing rod according to the fourth embodiment of the present invention will be described. As shown in Figure 8, the shape of the cylindrical body 4C in the fourth embodiment differs from that of the second embodiment. The fishing rod 1C according to the fourth embodiment will be described focusing on the differences from the second embodiment.

[0045] As shown in Figure 8, the cylindrical body 4C comprises a main body portion 41C and an extension portion 42C. The main body portion 41C is cylindrical and hollow. The extension portion 42C is continuous with the rear end of the main body portion 41C and is cylindrical. A stepped portion 42C1, which is smaller in diameter than other parts, is formed in the center of the extension portion 42C. The extension portion 42C itself does not come into contact with the rod 2. A cover member 61 is provided at the rear end of the extension portion 42C to cover the rear end. The cover member 61 may be omitted.

[0046] The fishing rod 1C described above can achieve substantially the same effects as the first embodiment. That is, the cylindrical body 4C may be attached to the rear end of the reel seat 3, or it may have a composite shape with steps, as in the extended portion 42C. This allows for variations in the grip shape.

[0047] While embodiments of the present invention have been described above, the design can be modified as appropriate without violating the spirit of the invention. For example, in this embodiment, the cylindrical body 4 is attached to the outside of the fixed hood 36, but it is not limited to this. For example, if the front end of the reel seat is formed to be long, it may be attached in front of the fixed hood. Also, in this embodiment, the cylindrical body 4 is attached to the outside of the fixed hood 36, but the cylindrical body may be attached to the outside of the movable hood. Furthermore, in the cylindrical body 4 of the first embodiment, the extended portion 42 is reduced in diameter, but it may have a constant outer diameter, be increased in diameter towards the front, or have a composite shape with bumps and dips.
