Description

Technical Field

[0001] This disclosure relates to a reel seat and a fishing rod including the reel seat. Background Technology

[0002] In fishing rods using reels, a reel holder is attached to the rod body to mount the reel. This reel holder has a retaining cover for securing one reel leg to the holder, through which the rod body inserts and passes. The reel holder also has a convex thread with a length in the direction opposite to the retaining cover and in which the other reel leg is secured. The reel holder includes a movable cover that can move axially in the fishing rod by rotating a nut threaded to the convex thread. The movable cover and the retaining cover securely support the reel leg, thereby fixing the reel in place.

[0003] Japanese Patent Publication No. 2001-61381 discloses a fishing rod including a movable cover. (Reference) Figure 1 The reel 2 is mounted on the reel seat 3. The reel seat 3 includes a fixed cover 4 that fixes one leg 2a of the reel 2 and a movable cover 5 that fixes the other leg 2b of the reel 2. One leg 2a of the reel 2 is covered by the fixed cover 4, and the other leg 2b of the reel 2 is covered by the movable cover 5, thereby fixing the reel 2 to the reel seat 3. When the nut 6 located on one side of the movable cover 5 is rotated, the movable cover 5 can move along the central axis O of the fishing rod 1 toward or away from the fixed cover 4.

[0004] like Figure 1 As shown, when a user grips the reel seat 3 during fishing, the nut 6 may be accidentally rotated by hand. Therefore, loosening of the reel 2 and reel seat 3 should be prevented. For this purpose, the nut 6 in a conventional reel seat 3 is divided into a cover side 6a and an opposite cover side 6b. During fishing, the user's fingers or palm can be positioned on the cover side 6a, while the opposite cover side 6b is gripped when the reel 2 is fixed or not. A knurled portion 6c is formed on the outer peripheral surface of the nut 6 to prevent slippage between the hand and the nut 6.

[0005] In the conventional reel seat 3, the nut 6 requires a relatively long cover side 6a to prevent it from rotating during fishing. Conversely, the cover side 6b is also required to facilitate rotation of the nut 6. Therefore, conventional nuts 6 have limitations in providing compact or lightweight nuts. Summary of the Invention

[0015] In one embodiment, the length of the operating part in the axial direction can be in the range of 7 mm to 10 mm.

[0016] In one embodiment, the movable cover may include an annular portion adjacent to the nut. The difference between the outer circumference of the operating portion and the outer circumference of the annular portion may be in the range of 0 mm to 1 mm.

[0017] In one embodiment, the winding reel seat may further include: a locking ring disposed on one side of the nut and coupled to the seat body for axial movement; and a locking nut coupled to the locking ring for circumferential rotation and threaded to the seat body for circumferential rotation. When the locking nut rotates, the locking ring may press the nut toward the retaining cover in the axial direction.

[0018] In one embodiment, the difference between the outer circumference of the operating part and the outer circumference of the locking ring can be in the range of 0 mm to 1 mm.

[0019] In one embodiment, the nut may include a plurality of ridges, each ridge being disposed between adjacent recesses of a plurality of recesses and arranged in a circumferential direction.

[0020] The disclosed embodiments relate to a fishing rod including a reel seat. According to one embodiment, the fishing rod includes a rod body and a reel seat, according to the above embodiment, coupled to the rod body.

[0061] Figure 2 This is a view showing a winding wheel holder 100 according to one embodiment. Figure 3This is a view illustrating the process of assembling the movable cover assembly 130 onto the base 110 in one embodiment. Figure 4 This is a view showing the state in which the movable cover assembly 130 is assembled to the base 110 in one embodiment. Figure 5 This is a view showing the connection between the nut 150 and the movable cover 140 in one embodiment. Figure 6 This is a side view illustrating the process of assembling the movable cover 140 to the base 110 in one embodiment. Figure 7 yes Figure 4 The movable cover assembly 130 along Figure 4 Sectional view of line VII-VII.

[0062] refer to Figure 2 The reel holder 100 is configured to secure the reel 20 to the fishing rod. The reel 20 includes a support 23 extending toward the reel holder 100 and a pair of reel legs 21 and 22 extending opposite to each other in an axial direction D1 from the lower end of the support 23. The pair of reel legs 21 and 22 are coupled to the reel holder 100, thereby securing the reel 20 to the fishing rod. The pair of reel legs 21 and 22 includes a first leg 21 and a second leg 22, the first leg 21 extending toward the retaining cover 111 of the fishing rod relative to the support 23 of the reel 20, and the second leg 22 extending in the opposite direction to the first leg 21 (or toward the movable cover 140).

[0063] The reel holder 100 includes a seat 110 connected to the rod 30. The seat 110 is configured to support a pair of reel legs 21 and 22.

[0064] The reel holder 100 may include a gripper 113 connected to a seat 110. The gripper 113 may be configured such that a portion of the seat 110 is inserted into the gripper. The gripper 113 may be configured such that when the gripper 113 is connected to the seat 110, there is no step difference at the boundary between the gripper and the seat 110.

[0065] A retaining cover 111 and a movable cover assembly 130 secure the winding wheel legs 21 and 22 to the base 110. The base 110 includes a retaining cover 111 configured to cover the first leg 21 of the pair of winding wheel legs 21 and 22. The retaining cover 111 may be integrally formed with the base 110, or it may be attached to the base 110 after a component configured to be separate from the base 110.

[0066] The movable cover assembly 130 includes a movable cover 140 and a nut 150. The movable cover 140 is configured to cover the second leg 22 of a pair of winding wheel legs 21 and 22. The nut 150 is configured to move the movable cover 140 along the central axis O (or in the axial direction D1). The movable cover 140 is coupled to the base 110 so as to be movable in the axial direction D1. When the movable cover 140 moves to cover the second leg 22, the second leg is fixed to the base 110.

[0067] In this disclosure, the description of covers 111 and 140 covering the winding wheel legs 21 and 22 means that the covers are disposed on at least a portion of the winding wheel legs 21 and 22, and at least a portion of the winding wheel legs 21 and 22 overlaps with at least a portion of the covers 111 and 140 in the vertical direction.

[0068] refer to Figures 2 to 4 A first gap G1 exists below the fixed cover 111. When the end of the first leg 21 is accommodated in the first gap G1, the fixed cover 111 covers the end of the first leg 21. A second gap G2 exists between the movable cover 140 and the seat 110. The end of the second leg 22 is accommodated in the second gap G2, and the movable cover 140 covers the end of the second leg 22.

[0069] The fixed cover 111 and the movable cover 140 can press down on the winding wheel legs 21 and 22 while covering them. (See reference...) Figure 2 The winding wheel legs 21 and 22 may have inclined surfaces that gradually decrease in the direction away from the support member 23, and the covers 111 and 140 may have a shape that gradually increases towards the support member 23. When the fixed cover 111 and the movable cover 140 approach each other in the axial direction D1 while in contact with the inclined surfaces of the winding wheel legs 21 and 22, the fixed cover 111 and the movable cover 140 may press the first leg 21 and the second leg 22 downward, respectively. Therefore, the winding wheel legs 21 and 22 can be tightly fitted between the seat 110 and the covers 111 and 140, and the winding wheel 20 can be firmly fixed to the winding wheel seat 100.

[0070] The movable cover 140 is coupled to the base 110 so that it can move along the central axis O in the axial direction D1. In this disclosure, the axial direction D1 refers to the direction parallel to the central axis O of the rod 30. The movable cover 140 is configured to selectively cover the second leg 22, which is the other of a pair of winding wheel legs 21 and 22, depending on the position of the movable cover on the base 110. For example, the movable cover 140 moving toward the fixed cover 111 covers the second leg 22, while the movable cover 140 moving away from the fixed cover 111 does not cover the second leg 22.

[0071] The seat 110 may include a guide groove 114 extending in the axial direction D1 on its outer surface. (See reference...) Figure 3 The guide groove 114 may be provided on each lateral side of the outer surface of the seat 110. The movable cover 140 includes a guide protrusion 146 received in the guide groove 114. The movable cover 140 may include a pair of guide protrusions 146 respectively received in a pair of guide grooves 114. The guide protrusions 146 extend in the axial direction D1. When the movable cover 140 is coupled to the seat 110, the guide protrusions 146 are received in the guide groove 114, and therefore, the movement of the movable cover 140 relative to the seat 110 is restricted to the axial direction D1.

[0072] Nut 150 is coupled to movable cover 140 and configured to adjust the position of movable cover 140 along central axis O. Nut 150 is configured to move along central axis O on base 110 by rotation of itself about central axis O. Nut 150 may be threadedly coupled to base 110 so as to be rotatable in the circumferential direction D2 of central axis O. Base 110 includes a convex thread 112 having a rotation axis on central axis O on its outer circumferential surface, and nut 150 may be threadedly coupled to convex thread 112. Nut 150 may include a concave thread 156 on its inner circumferential surface that engages with convex thread 112 of base 110. Due to the interaction of convex thread 112 and concave thread 156, nut 150 may move along central axis O on base 110 while rotating about central axis O.

[0073] refer to Figure 3 , Figure 5 and Figure 7 The movable cover 140 may include an annular portion 144 and a cover portion 142 extending from the annular portion 144. The annular portion 144 may have a shape surrounding the outer peripheral surface of the seat 110. The cover portion 142 extends from the upper semicircle of the annular portion 144 in the axial direction D1. Guide protrusions 146 may be provided at each of the two ends of the hood portion 142 in the circumferential direction D2.

[0074] Reference Figure 7 and Figure 8 The annular portion 144 may include an engagement groove 145 formed in the circumferential direction D2 on its inner circumferential surface. The nut 150 includes a connecting portion 152 that connects to the movable cover 140. The connecting portion 152 may include an engagement protrusion 153 formed in the circumferential direction D2 and received in the engagement groove 145 of the annular portion 144. When the connecting portion 152 of the nut 150 is inserted into the annular portion 144, the engagement protrusion 153 engages in the engagement groove 145, thus the nut 150 is rotatably coupled to the movable cover 140.

[0075] By rotating the nut 150, which is rotatably connected to the movable cover 140, the movable cover 140 can move along the central axis O on the base 110 together with the nut 150. For example, when the nut 150 rotates clockwise, the movable cover assembly 130 advances toward the fixed cover 111. When the nut 150 rotates counterclockwise, the movable cover assembly 130 retracts from the fixed cover 111. In this disclosure, clockwise and counterclockwise directions refer to the clockwise and counterclockwise rotation directions when the winding wheel seat 100 is viewed along the axial direction D1 from the movable cover 140 toward the fixed cover 111. Furthermore, in this disclosure, the term "advance" in relation to the movement of the movable cover 140, nut 150, etc., in the axial direction D1 refers to movement in the direction in which the movable cover 140 moves toward the fixed cover 111, and the term "retract" refers to movement in the direction in which the movable cover 140 moves away from the fixed cover 111.

[0076] The seat 110 may include a protrusion 116, which is positioned below the cover portion 142 when the movable cover 140 moves toward the fixed cover 111. That is, the protrusion 116 of the seat 110 is positioned adjacent to the cover portion 142 of the movable cover 140 in the circumferential direction D2. When the movable cover 140 moves toward the fixed cover 111 and the cover portion 142 is partially positioned above the protrusion 116, at least a portion of the guide protrusion 146 is covered by the protrusion 116 and may not be exposed to the outside of the winding reel seat 100.

[0077] The movable cover 140 may include a reinforcing cover 148 to prevent deformation of the movable cover 140 and the guide protrusion 146. The reinforcing cover 148 surrounds the exterior of the movable cover 140 and the guide protrusion 146. The reinforcing cover 148 may be made of a material with higher stiffness than the material of the movable cover 140 or the guide protrusion 146. For example, the movable cover 140 and the guide protrusion 146 may be made of plastic, and the reinforcing cover 148 may be made of a metal such as aluminum or stainless steel.

[0078] Figure 8 This is a side view of a nut 150 according to one embodiment. Figure 9 This is a front view of a nut 150 according to one embodiment. Figure 10 yes Figure 8 Nut 150 along Figure 8 A sectional view of line XX. Figure 11 yes Figure 9 Nut 150 along Figure 9 A sectional view of line XI-XI.

[0079] Reference Figure 8The nut 150 may be configured in a generally annular shape. The nut 150 includes a connecting portion 152 and an actuating portion 154 extending from the connecting portion 152. The connecting portion 152 is configured to engage with a movable cover 140 so that it can rotate in the circumferential direction D2. The actuating portion 154 is the portion that is actuated to rotate the nut 150. The actuating portion 154 is exposed to the outside of the winding reel seat 100 and can be gripped by a user.

[0080] The actuating portion 154 of the nut 150 may have a generally cylindrical shape. In the accompanying drawings of this disclosure, the actuating portion 154 of the nut 150 has a cylindrical shape with a constant radius along the axial direction D1, but the embodiments of this disclosure are not limited thereto. In other embodiments, the actuating portion 154 of the nut 150 may have a conical shape, the radius of which varies along the axial direction D1.

[0081] Multiple recessed portions 160 are provided in the operating portion 154 of the nut 150 in the circumferential direction D2. (See reference...) Figure 7 and Figure 8 Each recessed portion 160 may be defined by a bottom surface 161 and a side surface, the bottom surface 161 being recessed from the outer peripheral surface 157 of the operating portion 154 toward the center of the nut 150, and the side surface extending from the edge of the bottom surface 161.

[0082] Reference Figures 8 to 11 The side surfaces of the recessed portion 160 may include a pair of first side surfaces 162a and 162b extending from the two edges of the bottom surface 161 in the circumferential direction D2, and a pair of second side surfaces 163a and 163b extending from the two edges of the bottom surface 161 in the axial direction D1. The pair of first side surfaces 162a and 162b face each other in the circumferential direction D2, and the pair of second side surfaces 163a and 163b face each other in the axial direction D1. The pair of first side surfaces 162a and 162b may extend in the axial direction D1, and the pair of second side surfaces 163a and 163b may extend in the circumferential direction D2.

[0083] When viewed along the axial direction D1, the recessed portion 160 has a shape that is concave in the direction toward the central axis O. (Refer to...) Figure 10 The recessed portion 160 may be partially defined by a bottom surface 161 and a pair of first side surfaces 162a and 162b. The bottom surface 161 is recessed from the protruding surfaces 158 toward the central axis O between two of the plurality of protruding surfaces 158, and the pair of first side surfaces 162a and 162b extend from the bottom surface 161 to the two protruding surfaces 158, respectively.

[0084] When viewed from the side, the recessed portion 160 has a shape that is concave in the direction toward the central axis O. (Refer to...) Figure 11 The recessed portion 160 may be partially defined by a bottom surface 161 and a pair of second side surfaces 163a and 163b. The bottom surface 161 is recessed from the outer peripheral surface 157 toward the central axis O, and the pair of second side surfaces 163a and 163b extend from the bottom surface 161 to the two outer peripheral surfaces 157, respectively.

[0085] Reference Figure 10 and Figure 11 The side surfaces of the recessed portion 160 can extend obliquely from the bottom surface 161. For example, the first side surfaces 162a and 162b can form an angle greater than 90 degrees with the bottom surface 161, and the second side surfaces 163a and 163b can form an angle greater than 90 degrees with the bottom surface 161.

[0086] Reference Figure 8 Since the side surfaces of the recessed portion 160 are inclined relative to the bottom surface 161, each side surface of the recessed portion 160 may have a trapezoidal shape when viewed from above, having an edge that serves as the adjacent bottom surface as the shorter base. The trapezoidal shape in this disclosure is not limited to a trapezoid defined by a strict mathematical definition. A trapezoidal shape may include a shape in which one of two bases positioned opposite to each other appears shorter than the other, and the distance between a pair of inclined sides at the ends of each of the two bases gradually increases from the shorter base toward the longer base. Furthermore, the trapezoidal shape in this disclosure may include an approximate trapezoidal shape in which the sides defining the trapezoid are curves rather than straight lines.

[0087] refer to Figure 8 and Figure 11 Each of the first side surfaces 162a and 162b may have a trapezoidal shape in its lower surface 162c, with the edge adjacent to the bottom surface 161 serving as a short base. Each of the second side surfaces 163a and 163b may have a trapezoidal shape, with the edge adjacent to the bottom surface serving as a short base.

[0088] The side surfaces of the recessed portion 160 may extend from the corresponding edges of the bottom surface 161 to form an obtuse angle with the bottom surface 161. A pair of first side surfaces 162a and 162b may extend such that the distance between them in the circumferential direction D2 gradually increases in the direction away from the bottom surface 161. A pair of second side surfaces 163a and 163b may extend such that the distance between them in the axial direction D1 gradually increases in the direction away from the bottom surface 161.

[0089] Because the side surface of the recessed portion 160 slopes from the bottom surface 161, the contact area between the user's fingertip and the surface defining the recessed portion 160 can be increased. Therefore, force can be easily applied to the recessed portion 160 in both the circumferential direction D2 and the axial direction D1 by the fingertip. When the side surface of the recessed portion 160 extends perpendicularly from the bottom surface 161, the contact area between the fingertip and the surface of the recessed portion 160 will decrease, and the fingertip applying force to the small contact area will be pressed with high pressure, potentially causing discomfort such as pain. As a result, the nut 150 cannot rotate with sufficient force, and the movable cover 140 cannot press the winding wheel legs 21 and 22 with sufficient force. Therefore, there may be a problem of unstable connection between the winding wheel 20 and the winding wheel seat 100. In the recessed portion 160 according to one embodiment of the present disclosure, the side surface of the recessed portion is formed to slope from the bottom surface 161. Therefore, the contact area between the finger and the recessed portion 160 is increased, and thus, a relatively strong force can be applied to the nut 150 without discomfort. The movable cover 140 can be moved toward the fixed cover 111 by means of the nut 150, so that the movable cover 140 can fully press the winding wheel legs 21 and 22, and this allows the winding wheel 20 to be securely connected to the winding wheel seat 100.

[0090] Furthermore, since the recessed portion 160 of the nut 150 according to one embodiment of the present disclosure is recessed toward the central axis O even when viewed from a side view, a force in the axial direction D1 can be easily applied to the nut 150. Applying a force to the nut 150 in the axial direction D1 can further facilitate the movement of the movable cover 140 in the axial direction D1. For example, when the movable cover 140 moves toward the fixed cover 111 by rotating the nut 150 clockwise, pushing the nut 150 toward the fixed cover 111 can more easily advance the movable cover 140. Furthermore, when the movable cover 140 retracts from the fixed cover 111 by rotating the nut 150 counterclockwise, pulling the nut 150 in a direction away from the fixed cover can more easily retract the movable cover 140.

[0091] The nut 150 may include a protruding surface 158 having a larger outer circumferential radius than the outer circumferential surface 157. (See reference...) Figure 11Each of the first side surfaces 162a and 162b may include a lower surface 162c extending from the bottom surface 161 to the height of the outer peripheral surface 157, and an upper surface 162d extending from the lower surface 162c to the protruding surface 158. That is, due to the provision of the protruding surface 158, the height of the first side surfaces 162a and 162b (i.e., the difference (R4-R2) between the outer peripheral radius R4 of the protruding surface 158 and the outer peripheral radius R2 of the bottom surface 161) becomes higher. The first side surfaces 162a and 162b are surfaces on which a force is applied in the circumferential direction D2 by a fingertip. Therefore, as the height of the first side surfaces 162a and 162b from the bottom surface 161 becomes higher, the user can apply a stable and strong force to rotate the nut 150 by fingertip. Furthermore, the torque can be determined in part by the product of the magnitude of the force applied to the second side surfaces 163a and 163b and the distance from the central axis O to the point of application. As the height of the first side surfaces 162a and 162b increases, the point of force application can move away from the central axis O, thus allowing a stronger torque to be applied to the nut 150 with a relatively small force.

[0092] Reference Figure 7 and Figure 8 The nut 150 may include an inclined surface 159 extending in the axial direction D1 from the end of the protruding surface 158. The outer circumferential radius of the inclined surface 159 gradually decreases from the boundary between the inclined surface 159 and the protruding surface 158 toward either end of the operating portion 154 in the axial direction D1. At either end of the operating portion 154 in the axial direction D1, the outer circumferential radius of the inclined surface 159 may be equal to the outer circumferential radius of the outer circumferential surface 157. The operating portion 154 of the nut 150 contacts the movable cover 140 (or the annular portion 144 of the movable cover 140). Since the inclined surface 159 is disposed between the movable cover 140 and the protruding surface 158, inconvenience that occurs when a user grips the area between the movable cover 140 and the protruding surface 158 can be eliminated or minimized. Furthermore, the operating portion 154 of the nut 150 contacts the locking ring 180, which will be described later. Since the inclined surface 159 is positioned between the locking ring 180 and the protruding surface 158, inconvenience that occurs when a user grips the area between the locking ring 180 and the protruding surface 158 can be eliminated or minimized.

[0093] Multiple recessed portions 160 may be arranged at equal intervals in the circumferential direction D2 of the operating portion 154. For example, five recessed portions 160 may be arranged at equal intervals in the circumferential direction D2 of the operating portion 154. When viewed in the axial direction D1, the angle θ1 formed by a pair of first side surfaces 162a and 162b (i.e., the included angle between the pair of first side surfaces 162a and 162b) may be in the range of 144 degrees to 150 degrees. If the included angle θ1 between the pair of first side surfaces 162a and 162b is less than 144 degrees, there may be a problem that the metal mold for molding the nut 150 becomes complicated, as will be discussed later. Figure 12 and 13 Therefore, the manufacturing cost of nut 150 increases. When the angle θ1 is greater than 150 degrees, there may be a problem where the fingertip easily slips when pushing the recessed portion 160. Furthermore, when the included angle θ1 of the pair of first side surfaces 162a and 162b is greater than 150 degrees, most of the force exerted by the fingertip on the first side surfaces 162a and 162b is directed towards the central axis O. In other words, regarding the thrust, the magnitude of the force in the circumferential direction D2 that actually rotates the nut 150 decreases. Therefore, although the nut 150 is securely tightened, the winding wheel 20 cannot be securely fixed to the winding wheel seat 100; on the other hand, the securely tightened nut 150 cannot be easily loosened.

[0094] In one embodiment of this disclosure, five recesses 160 are provided in the circumferential direction D2, but this is merely exemplary. In other embodiments, the number of recesses 160 may be two to four, or six or more.

[0095] When viewed in the axial direction D1, the bottom surface 161 of the recessed portion 160 can have an arcuate shape centered on the central axis O. For example, the bottom surface 161 of the recessed portion 160 can have the same shape as the outer circumferential surface of a cylinder whose central axis lies on the central axis O. In this case, the ratio (R2 / R1*100) of the radius R2 of the bottom surface 161 of the recessed portion 160 to the outer circumferential radius R1 of the annular portion 144 can be in the range of 90% to 93%.

[0096] The nut 150 disclosed herein includes a plurality of recessed portions 160 in its outer peripheral surface 157, and the nut 150 can be easily rotated by engaging a fingertip with the recessed portion 160. Therefore, the overall length of the nut 150 can be shortened, and the nut 150 can be provided in a compact size. The length of the operating portion 154 of the nut 150 in the axial direction D1 can be in the range of 7 mm to 10 mm.

[0097] The outer radius of the portion of the operating part 154 of the nut 150 adjacent to the movable cover 140 can be equal to the outer radius of the annular portion 144. The difference between the outer radius of the operating part 154 of the nut 150 and the outer radius of the annular portion 144 can be in the range of 0 mm to 1 mm. (Refer to...) Figure 7 The difference (R3-R1) between the outer circumferential radius R3 of the outer circumferential surface 157 of the nut 150 and the outer circumferential radius R1 of the annular portion 144 can be in the range of 0 mm to 1 mm. As another example, the difference (R4-R1) between the outer circumferential radius R4 of the protruding surface 158 of the nut 150 and the outer circumferential radius R1 of the annular portion 144 can be in the range of 0 mm to 1 mm.

[0098] Figure 12 This is a view showing the closed state of a metal mold assembly for forming a nut 150 according to one embodiment. Figure 13 It is shown Figure 12 A view of the metal mold assembly in its open state.

[0099] Reference Figure 12 and Figure 13 According to one embodiment, the nut 150 can be manufactured using a metal mold assembly consisting of an upper mold M1 and a lower mold M2. The upper mold M1 and the lower mold M2 may each include cavities C1 and C2 corresponding to a portion of the shape of the nut 150.

[0100] The nut 150 may include five recessed portions 160 equally spaced along the circumferential direction D2. (See reference...) Figure 12 The nut 150 may include a first recessed portion 160a, a second recessed portion 160b, a third recessed portion 160c, a fourth recessed portion 160d, and a fifth recessed portion 160e arranged sequentially in a counterclockwise direction. The nut 150 may also include a first protruding surface 158a, a second protruding surface 158b, a third protruding surface 158c, a fourth protruding surface 158d, and a fifth protruding surface 158e arranged sequentially in a counterclockwise direction.

[0101] The nut 150 can be formed by a metal mold assembly such that the center of the second recessed portion 160b and the center of the fifth protruding surface 158e are aligned on the V-axis. The cavities C1 and C2 of the upper mold M1 and the lower mold M2 can be arranged symmetrically about the V-axis.

[0102] The upper mold M1 may include a cavity C1 that forms the surface of the nut, extending counterclockwise from a first boundary B1 between a first recess 160a and a first protruding surface 158a to a second boundary B2 between a third recess 160c and a fourth protruding surface 158d. The lower mold M2 may include a cavity C2 that forms the remaining surface of the nut 150, i.e., the surface of the nut extending counterclockwise from the second boundary B2 to the first boundary B1. The H-axis is a horizontal axis connecting the first boundary B1 and the second boundary B2.

[0103] The included angle θ1 of a pair of first side surfaces 162a and 162b in each of the five recesses 160 can be in the range of 144 degrees to 150 degrees. When the angle between a pair of first side surfaces 162a and 162b facing each other in the circumferential direction D2 is 144 degrees or greater, in the four quadrants formed by the H-axis and V-axis, the angle θ2 formed by any surface of the nut 150 present in the first quadrant Q1 with the H-axis is 90 degrees or greater. Specifically, the angle formed by the first side surface 162a between the bottom surface 161 of the first recess 160a and the second protruding surface 158b with the H-axis is not an acute angle. Furthermore, the angle θ3 formed by any surface of the nut 150 present in the second quadrant Q2 with the negative H-axis is 90 degrees or greater. Specifically, the angle formed by the first side surface 162a between the bottom surface 161 of the third recess 160a and the third protruding surface 158c with the negative H-axis is not an acute angle. In other words, in the nut 150 formed by the upper mold M1, the width W1 in the H-axis direction monotonically decreases upwards (i.e., in the direction of the positive V-axis). Therefore, when the cavity C1 of the upper mold M1 is opened, a portion of the nut 150 formed by the upper mold M1 (i.e., the portion located in the first quadrant Q1 and the second quadrant Q2 in the HV plane) can be easily separated from the upper mold M1. When the included angle θ1 of the pair of first side surfaces 162a and 162b is less than 144 degrees, the nut 150 will include a portion where the width W1 in the H-axis direction increases upwards. In this case, due to the interference between the nut 150 and the upper mold M1, it is difficult to separate the nut 150 from the upper mold M1.

[0104] When the included angle θ1 between the pair of first side surfaces 162a and 162b is 144 degrees or greater, the width W2 of the nut 150 in the H-axis direction (which exists in the third quadrant Q3 and the fourth quadrant Q4) also decreases monotonically downward (i.e., in the direction of the negative V-axis). Therefore, when the cavity C2 of the lower mold M2 is opened, a portion of the nut 150 formed by the lower mold M2 (i.e., the portion located in the third and fourth quadrants in the HV plane) can be easily separated from the lower mold M2.

[0105] When the included angle θ1 of a pair of first side surfaces 162a and 162b is 144 degrees or greater, a surface with the following characteristics can be used: Figure 12 and Figure 13 The simple structure of the metal mold assembly shown is used to form the nut 150. This can improve the precision of the metal mold and save on the cost of manufacturing and maintaining the metal mold.

[0106] Figure 14 This is a view showing the movement of the movable cover 140 toward the fixed cover 111 by rotating the nut 150 with a fingertip. Figure 15 This is a view showing the movement of retracting the movable cover 140 from the fixed cover 111 by rotating the nut 150 with a fingertip. Figure 16 This is a view showing the state in which the winding reel seat 100 is gripped according to one embodiment.

[0107] Reference Figure 14 The user positions the tips of their index finger F2 and thumb F1 in the recessed portion 160 and rotates the nut 150 clockwise around the central axis O, thereby allowing the movable cover 140 to move forward. (See reference...) Figure 15 The user positions the tips of the index finger F2 and the thumb F1 in the recessed portion 160 and rotates the nut 150 counterclockwise around the central axis O, thereby allowing the movable cover 140 to retract.

[0108] When a fingertip is accommodated in the recess 160, the first side surfaces 162a and 162b of the recess 160 prevent the fingertip from sliding in the circumferential direction D2 or the axial direction D1. Therefore, forces in the circumferential direction D2 and the axial direction D1 can be easily and stably applied to the nut 150. The user can easily rotate the nut 150 by applying force to the first side surfaces 162a and 162b of the recess 160 in the circumferential direction D2 with their fingertip.

[0109] The recessed portion 160 of the nut 150 has second side surfaces 163a and 163b that can receive forces in the axial direction D1. Therefore, the user can rotate the nut 150 while simultaneously pushing or pulling the second side surfaces 163a and 163b. That is, the user can simultaneously apply a force in the circumferential direction D2 and an axial direction D1 to the nut 150 using their fingertips. The nut 150 is threaded to the housing 110, and when rotated clockwise, the nut 150 moves in the axial direction D1. Therefore, pushing or pulling the nut 150 in the axial direction D1 facilitates its rotation when the user rotates it with their fingertips. Furthermore, as the nut 150 rotates, the user's fingertips also move along the axial direction D1 while being accommodated in the recessed portion 160 of the nut 150. Therefore, pushing or pulling the nut 150 in the axial direction D1 is more comfortable when the nut 150 rotates. According to one embodiment of this disclosure, since the user can push or pull the nut 150 while rotating it, the pressure felt by the user when rotating the nut 150 can be eliminated or minimized.

[0110] Reference Figure 16 Compared to the outer peripheral surface 157 or protruding surface 158 of the nut 150, the recessed portion 160 is recessed towards the central axis O. Therefore, during fishing, the inner surface of a fingertip or finger can rest on the outer peripheral surface 157 or protruding surface 158 of the nut 150, except for the recessed portion 160. This prevents the nut 150 from being unintentionally rotated by the fingers during fishing.

[0111] Figure 17 This is a view showing a movable cover assembly 230 according to one embodiment. Figure 18 yes Figure 17 Front view of nut 250. Figure 19 It is shown Figure 17 A view of the nut 250 being gripped.

[0112] Reference Figure 17 and Figure 18 The nut 250 may include knurled portions 258 disposed between adjacent recesses 160 in a plurality of recesses 160. The knurled portions 258 may include a plurality of ridges 258a arranged in the circumferential direction D2. The ridges 258a extend in the axial direction D1. When viewed in the axial direction D1, the ridges 258a may have a radially convex shape. Grooves 258b extending in the axial direction D1 are disposed between adjacent ridges 258a. Figure 17 and 18 In the knurled portion 258, there are three ridges 258a, but this is only an example. The number of ridges 258a can be two, four or more.

[0113] refer to Figure 19 Because the nut 250 includes a knurled portion 258, the friction between the fingers and the operating portion 154 is further increased when the index finger F2 and thumb F1 are around the operating portion 154, and the fingers do not slip. Therefore, the nut 250 can be turned with greater force by hand. Furthermore, the friction between the hand and the nut 250 can be further increased when the fingertips are positioned in the recessed portion 160 during gripping.

[0114] Figure 20 This is a view illustrating the process of assembling the locking nut assembly 170 to the base 110 in one embodiment. Figure 21 This is a view showing the state in which the locking nut assembly 170 is engaged with the seat 110 in one embodiment. Figure 22 This is a view illustrating the process of attaching a locking ring 180 to a locking nut 190 in one embodiment. Figure 23 This is a side view showing the process of assembling the locking nut assembly 170 to the seat 110 in one embodiment. Figure 24 yes Figure 21 The movable cover assembly 130 and the locking nut assembly 170 are along Figure 21 A sectional view of line XXIV-XXIV.

[0115] Reference Figure 20 and Figure 21 The winding reel holder 100 may also include a locking nut assembly 170. The locking nut assembly 170 is coupled to the seat 110 and disposed on one side of the movable cover assembly 130. The locking nut assembly 170 is configured to prevent the nut 150 from loosening.

[0116] The locking nut assembly 170 includes a locking ring 180 and a locking nut 190. The locking ring 180 is disposed on one side of the nut 150 and coupled to the seat 110 so as to be movable in the axial direction D1. (See reference...) Figure 22 The locking ring 180 is connected to the locking nut 190, and the assembly of the locking ring 180 and the locking nut 190 (i.e., the locking nut assembly 170) is connected to the seat 110.

[0117] The locking ring 180 is connected to the locking nut 190 so that it can rotate in the circumferential direction D2. (See reference...) Figure 22 and Figure 24 The locking ring 180 may include an engaging protrusion 182 extending in the circumferential direction D2, and the locking nut 190 may include an engaging groove 192 configured to receive the engaging protrusion 182 of the locking ring 180. The locking ring 180 is coupled to the seat 110 so as to be movable in the axial direction D1. (See reference...) Figure 24The locking ring 180 may include a guide protrusion 184 on its inner circumferential surface, which is received in a guide groove 114 of the seat. The guide protrusion 184 of the locking ring 180 may extend in the axial direction D1.

[0118] A locking nut 190 is threadedly connected to a housing 110 so that it can rotate in the circumferential direction D2. The locking nut 190 may include a concave thread 194 on its inner circumferential surface, which threadedly connects to a convex thread 112 formed on the outer circumferential surface of the housing 110. (Refer to...) Figure 20 When the locking nut 190 is mounted on the seat 110 and rotates clockwise, the locking nut can advance along the convex thread 112 of the seat 110 in the axial direction D1.

[0119] The locking ring 180 may include an insertion portion 185 extending toward the nut 150. The insertion portion 185 is configured to be inserted into the nut 150. The nut 150 includes a receiving portion 155 configured to receive the insertion portion 185. The outer circumferential radius of the insertion portion 185 is smaller than the outer circumferential radius R5 of the locking ring 180. When the insertion portion 185 is inserted into the receiving portion 155 of the nut 150, the nut 150 surrounds the insertion portion 185 in the circumferential direction D2.

[0120] When the locking nut 190 rotates about the central axis O, the locking nut 190 moves in the axial direction D1, and the locking ring 180 also moves accordingly in the axial direction D1. Since the guide protrusion 184 of the locking ring 180 moves along the guide groove 114, the locking ring 180 moves only in the axial direction D1 and does not rotate.

[0121] Reference Figure 23 and Figure 24 When the locking nut 190 is rotated clockwise, the front surface 181 of the locking ring 180 can contact the rear surface 151 of the nut 150. When the locking nut 190 is forcefully rotated, the locking ring 180 can forcefully push the rear surface 151 of the nut 150 against the movable cover 140. To loosen the nut 150, the nut 150 needs to move backward (i.e., away from the fixed cover 111). However, with the locking ring 180 pushing the nut 150, the nut 150 cannot move backward. Therefore, by pushing the nut 150 with the locking ring 180, the nut 150 can be prevented from being loosened from the seat 110.

[0122] The outer radius of the portion of the operating part 154 of the nut 150 adjacent to the locking ring 180 can be equal to the outer radius of the locking ring 180. The difference between the outer radius of the operating part 154 of the nut 150 and the outer radius of the locking ring 180 can be in the range of 0 mm to 1 mm. The difference (R3-R5) between the outer radius R3 of the outer circumferential surface 157 of the nut 150 and the outer radius R5 of the locking ring 180 can be in the range of 0 mm to 1 mm. The difference (R4-R5) between the outer radius R4 of the protruding surface 158 of the nut 150 and the outer radius R5 of the locking ring 180 can be in the range of 0 mm to 1 mm.

[0123] Figure 25 This is a view showing the movement of the movable cover 140 toward the fixed cover 111 with the locking nut assembly 170 engaged with the base 110. Figure 26 This is a view showing the movement of the movable cover 140 retracting from the fixed cover 111 with the locking nut assembly 170 engaged with the base 110. (Refer to...) Figure 25 and 26 Even with the locking nut assembly 170 assembled to the base 110, the nut 150 can be easily rotated. The user can rotate the nut 150 using only their fingertips by inserting their fingertips into the recessed portion 160 of the nut 150 and applying force to the nut 150 in the circumferential direction D2. Therefore, since the force of the finger can be concentrated on the recessed portion 160 of the nut 150, the user can easily rotate the nut 150 without inconvenience, even when the locking nut assembly 170 is close to the nut 150.

Fishing rods 10 and 10' may include the reel seat 100 of this disclosure. (See also...)

[0126] So far, the technical concept of this disclosure has been described with reference to some embodiments and examples shown in the accompanying drawings. However, it should be understood that various substitutions, modifications, and alterations can be made without departing from the technical concept and scope of this disclosure, which would be understood by one of ordinary skill in the art. Furthermore, it should be understood that such substitutions, modifications, and alterations fall within the scope of the appended claims.
