[0001] cross-reference

[0002] This application claims priority based on Japanese Patent Application 2022-099912 (filed on June 21, 2022), the contents of which are incorporated herein by reference in their entirety.

[0003] The present invention relates to a nut, a reel holder for a fishing rod having the nut, and a fishing rod having the reel holder for a fishing rod. Background Technology

[0004] Various devices for securing rod mounts of fishing reels to fishing rods are known in the past. For example, the reel securing device disclosed in Patent Document 1 includes a reel base body with a mounting portion for holding the rod mount of the fishing reel. A retaining cover is provided at one end of the reel base body to secure one end of the rod mount. A movable cover is mounted at the other end of the reel base body, movable relative to the retaining cover.

[0005] The movable cover is configured to include: an insertion part into which the other end of the fishing rod mounting foot can be inserted; and an operating knob that is rotatably mounted in the insertion part. The operating knob is configured to include: a cylindrical base that engages with a threaded portion formed on the other end of the reel holder body; and a decorative cover component mounted on the outer peripheral surface of the base. The cover component is fixed to the base using an adhesive. Adhesive is applied to both the outer peripheral surface of the base and the inner peripheral surface of the cover component.

[0006] Furthermore, Patent Document 2 discloses a nut for a fishing rod reel holder. This nut engages with the external thread of the reel holder body and is used to move a movable cover. It comprises: an inner cylinder having an internal thread on its inner circumferential surface that engages with the external thread of the reel holder body; and an outer cylinder fixed to the outside of the inner cylinder, its outer circumferential surface forming at least a portion of the outer circumferential surface of the nut. The outer cylinder has a through hole extending in the inward and outward directions, and a fixing portion for fixing the outer circumferential surface of the inner cylinder and the inner circumferential surface of the outer cylinder at a position farther from the movable cover than the through hole. Preferably, the fixing portion has at least one of an adhesive portion and a threaded portion. When the fixing portion has an adhesive portion, the outer circumferential surface of the inner cylinder and the inner circumferential surface of the outer cylinder can be easily fixed by adhesion.

[0009] Patent Document 2: Japanese Patent Application Publication No. 2020-89310 Summary of the Invention

[0010] However, in the cable reel fixing device disclosed in Patent Document 1, adhesive is applied to both the outer peripheral surface of the base and the inner peripheral surface of the cover member. Therefore, during installation, excess adhesive may overflow from the end of the cover member, damaging the decorative appearance. Furthermore, when a cover member with a through-hole is used to improve the decorative appearance of the movable cover, there is a problem that overflowing adhesive can easily enter the through-hole. Moreover, even when using a cover member with a through-hole, the area where the through-hole can be formed is limited in order to bond the inner surface of the cover member to the base.

[0011] Furthermore, although the nut for moving the movable cover disclosed in Patent Document 2 can achieve a high degree of decoration and can rotate smoothly, there is a problem that, since a fixing part is provided to fix the outer circumferential surface of the inner cylinder and the inner circumferential surface of the outer cylinder, and the outer circumferential surface of the inner cylinder and the inner circumferential surface of the outer cylinder are fixed by adhesive or screw fixing structure, it is impossible to form a through hole in the area of ​​the fixing part, which restricts the area where a through hole can be formed. As a result, there is still a limitation in improving the decoration.

[0012] The present invention was made in view of the above circumstances, and the technical problem to be solved is to provide a nut that not only reliably fixes the outer cylindrical part and the inner cylindrical part and allows for smooth rotation, but also significantly improves the decorative appearance, a fishing rod reel holder having the nut, and a fishing rod having such a fishing rod reel holder.

[0023] In one embodiment of the present invention, the nut is configured such that the diameter of the outer cylindrical portion is in the range of 10 mm to 30 mm.

[0024] One embodiment of the present invention relates to a fishing rod configured to have a fishing rod reel seat and a rod body, wherein the fishing rod reel seat has any of the nuts described above.

[0025] An embodiment of the present invention relates to a fishing rod reel holder comprising: a reel holder body having a reel foot holding portion for holding reel feet; a movable cover guided by the outside of the reel holder body and configured to be movable along the axial direction of the reel holder body; and a nut disposed on the outside of the reel holder body for moving the movable cover in the axial direction.

Detailed Implementation

[0036] The embodiments of the fishing rod according to the present invention will now be described in detail with reference to the accompanying drawings. In the multiple drawings, common components are labeled with the same reference numerals. For ease of explanation, the drawings are not necessarily drawn to an exact scale; this should be noted.

[0037] Figure 1 This figure illustrates one embodiment of the fishing rod according to the present invention. As shown, a fishing rod 1 according to one embodiment of the present invention includes: a rod body 2; a reel 6 mounted on the rod body 2 via a reel holder 9; and a fishing line guide 10 mounted on the rod body 2. In the illustrated embodiment, the reel holder 9 and the fishing line guide 10 each correspond to mounting parts mounted on the outer peripheral surface of the rod body.

[0038] The rod body 2 is constructed, for example, by connecting the first section 3, the middle section 5, and the tip section 7. These rod bodies are joined, for example, by a plug-in joint. The first section 3, the middle section 5, and the tip section 7 can be joined by a pull-out method, a reverse plug-in method, a sleeve method, or any other known joining method. The rod body 2 can also be constructed from a single rod body.

[0039] The first section 3, the middle section 5, and the tip section 7 are, for example, tubular bodies made of fiber-reinforced resin. These tubular bodies are manufactured by winding a fiber-reinforced resin polyester film (prepreg) impregnated with a matrix resin in reinforcing fibers onto a mandrel, and then heating and curing the prepreg. The reinforcing fibers included in the prepreg can be, for example, carbon fiber, glass fiber, or any other known reinforcing fibers. The matrix resin included in the prepreg can be a thermosetting resin such as epoxy resin. After the prepreg is cured, the mandrel is removed. Furthermore, the outer surface of the tubular body is appropriately ground. Each rod section can also be made solid.

[0040] In the illustrated embodiment, multiple line guides 10 (line guides 10A to 10D) are provided on the first section 3, the middle section 5, and the tip section 7 to guide the fishing line released from the reel 6 mounted on the reel seat 9. More specifically, line guide 10A is provided on the first section 3, line guide 10B is provided on the middle section 5, and line guide 10C is provided on the tip section 7. Although a top guide 10D is provided at the top of the tip section 7, detailed description is omitted.

[0041] Next, refer to Figure 2 The reel holder 9, which includes a reel holder body 12 and a nut 8, will be described. The reel holder 9 includes a reel holder body 12, which has a reel foot mounting surface (reel foot mounting portion) 12a along its axial direction for mounting the reel foot 6a of a fishing reel 6. The reel holder body 12 is generally formed into a cylindrical shape. Furthermore, the reel holder body 12 is formed from a suitable material such as synthetic resin (e.g., polyamide synthetic fiber or ABS resin) or metal (e.g., SUS, aluminum, titanium, brass). The reel holder body 12 may be configured to have a length of, for example, 60-160 mm, but is not limited to this.

[0042] In addition, the reel holder body 12 is formed with a grip portion 12b, which has a curved outer surface. The curved outer surface slightly raises the opposite side of the reel foot mounting surface 12a, making it easy to grip when held by the hand by supporting the pad of the thumb or its proximal part.

[0043] The reel foot mounting surface 12a of the reel holder body 12 is formed to be flat, or formed to have a greater curvature and be substantially flat than other circumferential portions (e.g., grip portion 12b) adjacent to the reel foot mounting surface 12a of the reel holder body 12, and is formed to be Figure 2 The diagram shows the axial extension of the reel holder body 12. A retaining cover 14 is integrally mounted on one end (the rod end side) of the reel holder body 12. One end of the reel foot mounting surface 12a of the reel holder body 12 is disposed inside the retaining cover 14.

[0044] The reel holder body 12 has an integrally formed cylindrical body with a guide groove and a threaded portion 18 at the other end (the rod end side). A cylindrical portion mounting surface 16a is formed on the cylindrical body, connected to or slightly stepped on the reel foot mounting surface 12a of the reel holder body 12. In one embodiment of the invention, a step is formed between the reel foot mounting surface (reel foot mounting portion) 12a and the cylindrical portion mounting surface 16a, allowing for the placement of a back retaining portion of the reel foot holding portion 28, so that the back retaining portion of the reel foot holding portion 28 (described later) and the reel foot mounting surface 12a are as close as possible to a single plane. The cylindrical portion mounting surface 16a is also continuously formed on the threaded portion (external threaded portion) 18. At the other end (the rod end side), a movable cover 22 is axially movable on the outside of the cylindrical body and the threaded portion 18. Here, the cable reel holder body 12 and the movable cover 22, or the cable reel holder body 12 and the movable cover 22 and the nut 8 described later, are referred to as the cable reel holder 9, but details are omitted.

[0045] like Figure 2 As shown, on the fixing cover 14 of the cable reel holder body 12, the opening 14a that receives one end of the cable reel foot 6a opens toward the movable cover 22. The opening 14a of the fixing cover 14 is formed such that the height of the inner surface gradually decreases toward the front of the cable reel holder body 12. When one end of the cable reel foot 6a is inserted into the opening 14a and pressed by the opening 14a, force (pressing) is applied to the cable reel foot 6a toward the cable reel foot mounting surface 12a disposed inside the fixing cover 14.

[0046] Furthermore, the fixing cover 14 is not limited to being integrally mounted on the cable reel holder body 12. It can also be formed as a separate structure from the cable reel holder body 12 using metal or rigid synthetic resin, and can be firmly fixed to the cable reel holder body 12. In the case of being made of metal, it is preferable to place a resin component at the part that abuts against the cable reel foot 6a of the cable reel 6, so as to prevent damage to the components caused by metal-to-metal contact.

[0047] The movable cover 22 is formed in the shape of a sleeve, with an axial hole through which the threaded portion (external threaded portion) 18 of the reel holder body 12 passes, and has a cover body 26 and a reel foot retaining portion 28 fixed inside the cover body 26. A nut 8 according to one embodiment of the present invention is rotatably connected to the rear part (rod end side) of the cover body 26 of the movable cover 22. This nut 8 is formed, for example, of synthetic resin, metal, polyamide synthetic fiber, ABS resin, aluminum, brass, etc., the cover body 26 is formed, for example, of metal (SUS, brass), etc., and the reel foot retaining portion 28 is formed, for example, of polyamide synthetic fiber, etc.

[0048] The nut 8 has an internal thread 24 formed on its inner circumference that engages with the threaded portion (external thread) 18, while its outer circumference is designed to prevent slippage and facilitate rotation. The front end of the nut 8 is connected (locked) to the rear end of the cover body 26 in a state where it can rotate freely and is prevented from coming off. More specifically, the nut 8 has a locking portion 25 (see below). Figure 3 The locking part 23, which is locked to the rear end of the cover body 26 (see below), is locked in place. Figure 3 It can be configured to allow free relative rotation and prevent detachment. In addition, various connection structures between the nut 8 and the cover body 26 can be considered, and it is not limited to a specific shape.

[0049] The nut 8 is screwed into the threaded portion (external threaded portion) 18 of the reel holder body 12 and is configured to be rotatable. As described above, since the cover body 26 is connected to the nut 8, when the nut 8 is rotated in the positive direction relative to the threaded portion (external threaded portion) 18, the nut 8 approaches the fixed cover 14, and at the same time, the cover body 26 of the movable cover 22 approaches the fixed cover 14. On the other hand, when the nut 8 is rotated in the opposite direction relative to the threaded portion (external threaded portion) 18, the nut 8 separates from the fixed cover 14, and at the same time, the cover body 26 of the movable cover 22 separates from the fixed cover 14.

[0050] The cover body 26, which moves axially within the reel holder body 12 by the rotation of the nut 8, opens forward and to its inner circumference. It has an opening 26a that is fixed in the state when a reel foot retaining portion 28 is provided, which is used to accommodate the rear end of the reel foot 6a of the fishing reel 6. When the movable cover 22 is installed onto the threaded portion (external threaded portion) 18 of the reel holder body 12, the opening 26a of the cover body 26 faces the opening 14a of the fixed cover 14. Unlike the opening 14a of the fixed cover 14, the opening 26a of the cover body 26 is formed such that the height of its inner surface gradually decreases towards the rear.

[0051] Next, refer to Figure 2 , 3 Sections 4, 5, and 6 further describe in detail the nut 8 according to one embodiment of the present invention. Figure 3 This is a cross-sectional view showing the central axis of the nut 8 and the movable cover 22 according to one embodiment of the present invention. Figure 4 This is a partial exploded view of a nut 8 according to one embodiment of the present invention. Figure 5 , 6 The images show the front view and top view of each component of the nut 8 according to one embodiment of the present invention.

[0052] One embodiment of the present invention relates to a nut 8 for engaging with an external threaded portion 18 of a reel holder body 12 having a reel foot mounting portion 12a for mounting reel feet 6a, thereby moving a movable cover 22. The nut 8 comprises: a nut base 15 having an internal threaded portion 24 on its inner circumferential surface for engaging with the external threaded portion 18 of the reel holder body 12, and being secured to the movable cover 22 via its end; and an inner cylindrical portion 16 having a convex portion (not shown) or a concave portion 19, which is fixed to the outer surface of the nut base 15. The outer cylindrical portion 17 has a concave portion (not shown) or a convex portion 20 that engages with the convex portion (not shown) or the concave portion 19, thereby being fixed to the outer side of the inner cylindrical portion 16, and its outer peripheral surface becomes at least a part of the outer peripheral surface of the nut. The outer cylindrical portion 17 has a through hole 21 extending in the inward and outward directions. When viewed in the axial (X) direction of the outer cylindrical portion 17, it is positioned where at least a part of the through hole 21 overlaps with at least a part of the concave portion (not shown) or the convex portion 20. Alternatively, either the convex portion or the concave portion can be provided on the inner cylindrical portion 16, and either the concave portion or the convex portion can be provided on the outer cylindrical portion 17 in a manner that engages with either the convex portion or the concave portion. Furthermore, various considerations can be made regarding the shape, structure, size, and number of the through hole 21. Although detailed descriptions are omitted, as other forms, it is also possible to use a form that is formed as shown in the figure. Figure 7 The outer cylindrical portion 17 of the through hole 21 shown. Furthermore, the illustrated example is merely illustrative and not intended to limit to a specific form.

[0053] Here, as Figure 5 As shown in (a), when viewed along this axial direction, the through hole 21 is positioned at a location that overlaps with the region where the protrusion 20 is formed in the region extending along this axial direction. That is, in this specification, when the positions along this axial direction are the same, the protrusion 20 and the through hole 21, which are positioned at different circumferential positions when viewed in the circumferential direction of the outer cylindrical portion 17, can be defined as being at a "position that overlaps when viewed in the axial direction" even if the circumferential positions are different.

[0054] According to one embodiment of the present invention, a nut is provided that not only reliably secures the outer and inner cylindrical portions and allows for smooth rotation, but also significantly enhances its decorative appeal. More specifically, existing methods suffer from the problem that, for securing the outer and inner cylindrical portions, an area for fixing is required along a predetermined axial length for bonding or screw fastening, resulting in the inability to form decorative through-holes or similar features in this area substantially circumferentially (necessitating a sacrifice in decorative appeal). In contrast, the nut according to one embodiment of the present invention, because it can be positioned where the through-hole 21 formed on the outer cylindrical portion 17 overlaps with or at least partially overlaps with the protrusion 20, allows the through-hole 21 for enhancing decorative appeal to be provided in a wider area than before, enabling both reliable securing of the outer and inner cylindrical portions while significantly improving decorative appeal.

[0055] In one embodiment of the present invention, the nut 8 is provided with two or more convex portions and concave portions (in... Figure 5 In the example, two protruding portions 20 are provided on the outer cylindrical portion 17. Figure 6 In this example, two recessed portions 19 are provided on the inner cylindrical portion 16. Here, as... Figure 5 As shown, the two convex portions 20 are positioned approximately 180 degrees apart in the circumferential direction, but are not limited to these positions; they can be spaced at larger or smaller angles. Furthermore, when three convex portions 20 are provided, the circumferential distance between adjacent convex portions can be approximately 120 degrees, but is not limited to this. The same applies to the concave portion 10. Various considerations can be made regarding the number or position (circumferential and axial) of the convex portions 19 and concave portions 20, and the design is not intended to be limited to a specific shape. This allows for a secure locking of the inner and outer cylindrical portions.

[0056] As described above, in one embodiment of the present invention, the nut 8 may also have a convex portion on the inner cylindrical portion 16 and a concave portion on the outer cylindrical portion 17.

[0057] In one embodiment of the present invention, the nut 8 has a rectangular parallelepiped shape in terms of the shape of the convex portion 20 and the space occupied by the concave portion 20. However, it should be noted that in the case of a rectangular parallelepiped shape, due to practical machining constraints (e.g., end milling constraints), the ends, end faces, or corners may be rounded or R-shaped, thus not necessarily a mathematically strict shape. For example, even if the convex portion 20 is rectangular parallelepiped, the corner of the end face on the radially protruding side of the nut 8 may be rounded, and the outer end of the side surface in the radial direction of the nut 8 may be R-shaped. The top and side surfaces of the rectangular parallelepiped shape may also be bent to form a convex or concave shape. Furthermore, even if the convex portion 20 is not rectangular parallelepiped, for example, when viewed in a radial cross-section of the nut 8, it may be trapezoidal or inverted trapezoidal, and the corners may be appropriately rounded or R-shaped. Furthermore, the shape may also be a cube, but various shapes and structures are also possible; the illustrated examples are merely illustrative and not intended to limit to a specific form.

[0058] In one embodiment of the present invention, the nut 8 is configured such that, when it is a cube (e.g., a cuboid), the length of the long side of the convex portion 20 is in the range of 3 mm to 5 mm, the length of the short side of the convex portion 20 is in the range of 0.5 mm to 1.5 mm, and the height of the convex portion 20 is in the range of 0.3 mm to 1.0 mm. The dimensions of the convex portion 20 can be various; the illustrated example is merely illustrative and not intended to limit to a specific form. This allows for a secure locking of the inner and outer cylindrical portions.

[0059] In one embodiment of the present invention, the nut 8 is configured such that, when it is a cube (e.g., a cuboid), the length of the long side of the concave portion 19 is in the range of 3 mm to 5 mm, the length of the short side of the concave portion 19 is in the range of 0.5 mm to 1.5 mm, and the height of the concave portion 19 is in the range of 0.3 mm to 1.0 mm. The dimensions of the concave portion 19 can be various; the illustrated example is merely illustrative and not intended to limit to a specific form. This allows for a secure locking of the inner and outer cylindrical portions.

[0060] In one embodiment of the nut 8, the inner cylindrical portion 16 has a wall portion 27 at either end of its outer circumferential surface in the axial direction (the end opposite to the movable cover 22), and the outer cylindrical portion 17 is fixed to the inner cylindrical portion 16 in a manner that abuts against the wall portion 27 (see reference). Figure 3 Furthermore, in one embodiment of the nut 8, the nut base 15 has a stepped portion 29, and the inner cylindrical portion 16 and the outer cylindrical portion 17 are fixed to the nut base 15 in such a way that they abut against the sidewall 30 of the stepped portion 29 (see reference). Figure 3In this way, the inner and outer cylindrical parts can be reliably locked.

[0061] In addition, such as Figure 5 As shown in (a), in one embodiment of the present invention, the convex portion 20 may be provided on the end of the inner cylindrical portion 16 or the outer cylindrical portion 17 from the side of the movable cover 22 on the nut 8. Figure 5 (a) The range is any area from the left end in the left-right direction of the drawing to X. This range can be, for example, the area from that end to 5 mm. More preferably, this range can be the area from that end to 3 mm. In this way, a reliable locking of the inner and outer cylindrical parts can be achieved.

[0062] In one embodiment of the nut 8, the surface area occupied by the through hole 21 in the entire surface area of ​​the outer peripheral surface of the outer cylindrical portion 17 (the surface area of ​​the outer peripheral surface without the through hole) is in the range of 50% to 80% relative to the surface area of ​​the entire region of the outer peripheral surface of the outer cylindrical portion 17 that forms at least a part of the outer peripheral surface of the nut 8 (the surface area of ​​the outer peripheral surface without the through hole). This allows for a secure locking of the inner and outer cylindrical portions.

[0063] In one embodiment of the present invention, the nut 8 is configured such that the radial thickness of the outer cylindrical portion 17 is in the range of 0.3 mm to 1.5 mm. Furthermore, in another embodiment of the present invention, the nut 8 is configured such that the diameter of the outer cylindrical portion 17 is in the range of 10 mm to 30 mm.

[0064] One embodiment of the present invention relates to a fishing rod 1 configured to include a fishing rod reel holder 9 and a rod body 2, wherein the fishing rod reel holder 9 has any of the aforementioned nuts 8. Thus, a fishing rod with a fishing rod reel holder is provided, wherein the nut of the fishing rod reel holder not only reliably secures the outer and inner cylindrical portions and allows for smooth rotation, but also significantly improves its aesthetic appeal.

[0065] In addition, such as Figure 2 , 3As shown in Figure 4, a fishing rod reel holder 9 according to one embodiment of the present invention includes: a reel holder body 12, having a reel foot holding portion 12a for holding a reel foot 6a; a movable cover 22, guided by the outside of the reel holder body 12 and configured to move along the axial direction of the reel holder body 12; and a nut 8, provided on the outside of the reel holder body 12 for moving the movable cover 22 in the axial direction. The nut is characterized by having: a nut base 15, having an internal thread 24 on its inner circumferential surface that engages with the external thread 18 of the reel holder body 12 for moving the movable cover 22 in the axial direction, and being secured at its end. The movable cover 22 has an inner cylindrical portion 16 with a convex portion (not shown) or a concave portion 19, which is fixed to the outside of the nut base 15; and an outer cylindrical portion 17 with a concave portion (not shown) or a convex portion 20 that engages with the convex portion (not shown) or the concave portion 19, thereby being fixed to the outside of the inner cylindrical portion 16, and its outer peripheral surface becomes at least a part of the outer peripheral surface of the nut 8. The outer cylindrical portion 17 has a through hole 21 that extends in the inward and outward directions. When viewed in the axial direction of the outer cylindrical portion 17, at least a part of the through hole 21 and at least a part of the concave portion (not shown) or the convex portion 20 are arranged in an overlapping position.

[0066] According to one embodiment of the present invention, a fishing rod reel holder is provided, which not only reliably secures the outer cylindrical portion and the inner cylindrical portion and allows for smooth rotation, but also significantly enhances the aesthetics.

[0067] Next, the results of the test (torque test) will be explained, which confirmed the bonding strength (fixed strength) between the outer and inner cylindrical portions when using the nut according to one embodiment of the present invention. The test was conducted using a torque meter with a rod tube retainer, on which the rod tube was fixed, and the torque (using a torque meter) was measured when force was applied to the nut in the rotational direction. The nut is screwed into the body of a reel seat mounted on the rod tube, thus confirming that there were no problems with the bonding strength (fixed strength) over a wide range from 5 kgf·cm to 100 kgf·cm.

[0068] The result showed that even when using [equipment / technology]... Figure 4 , Figure 7Even with a nut on either of the outer cylindrical portions, the outer and inner cylindrical portions will not separate, maintaining good adhesive strength (fixing strength). Thus, according to an embodiment of the present invention, the nut can reliably fix the outer and inner cylindrical portions. Therefore, using the nut according to an embodiment of the present invention not only reliably fixes the outer and inner cylindrical portions and allows for smooth rotation, but also significantly improves the decorative effect.
