Description

[Technical Field]

[0001] The present disclosure relates to a reel seat and a fishing rod including the same. [Background technology]

[0002] A reel seat is attached to a fishing rod body for mounting the reel to the fishing rod. The reel seat has a fixed hood that secures the reel leg at one end of the reel to the reel seat body through which the fishing rod body is inserted, and a male screw of a certain length in the direction that secures the reel leg at the other end of the reel facing the fixed hood. The reel seat includes a movable hood that can be moved in the axial direction of the fishing rod by rotating a nut that is threadedly coupled to the male screw. The movable hood, together with the fixed hood, clamps the reel legs at both ends to secure the reel.

[0003] Japanese Patent Publication No. 2001-61381 (Patent Document 1) discloses a fishing rod including a movable hood. Referring to FIG. 1, a reel (2) is attached to a reel seat (3). The reel seat (3) includes a fixed hood (4) that secures one leg (2a) of the reel (2) and a movable hood (5) that secures the other leg (2b) of the reel (2). The other leg (2a) of the reel (2) is covered by the fixed hood (4), and the other leg (2b) of the reel (2) is covered by the movable hood (5), thereby securing the reel (2) to the reel seat (3). As a nut (6) located on one side of the movable hood (5) rotates, the movable hood (5) can move toward or away from the fixed hood (4) along the central axis (0) of the fishing rod (1).

[0004] As shown in Figure 1, when a user is holding the reel seat 3 while fishing, it is necessary to prevent the nut 6 from unintentionally rotating due to the user's hand, loosening the reel 2's connection to the reel seat 3. Therefore, the nut 6 of a conventional reel seat 3 is divided into a hood-side portion 6a where the user's fingers or palm may be placed while fishing, and a hood-side portion 6b that is gripped when securing or releasing the reel 2. The outer surface of the nut 6 is formed with a knurled portion 6c to prevent slippage between the hand and the nut 6.

[0005] The nut 6 of a conventional reel seat 3 must have a relatively long hood-side portion 6a to prevent the nut 6 from rotating during fishing, and the portion 6b on the opposite side of the hood must also be relatively long to allow for easy rotation of the nut 6. This limits the conventional nut 6 in that it is difficult to provide a compact or lightweight design. [Prior art documents] [Patent documents]

[0030] FIG. 2 shows a reel seat (100) according to one embodiment. FIG. 3 shows the process of assembling a movable hood assembly (130) to a seat body (110) according to one embodiment. FIG. 4 shows the movable hood assembly (130) assembled to the seat body (110) according to one embodiment. FIG. 5 shows the connection between a nut (150) and a movable hood (140) according to one embodiment. FIG. 6 is a side view showing the process of assembling a movable hood (140) to a seat body (110) according to one embodiment. FIG. 7 is a cross-sectional view of the movable hood assembly (130) of FIG. 4 taken along line VII-VII in FIG. 4.

[0031] Referring to Figure 2, the reel seat 100 is configured to secure the reel 20 to the fishing rod. The reel 20 includes a support 23 extending toward the reel seat 100 and a pair of reel legs 21, 22 extending in both directions from the lower end of the support 23 in the axial direction D1. The pair of reel legs 21, 22 are coupled to the reel seat 100, thereby securing the reel 20 to the fishing rod. The pair of reel legs 21, 22 includes a first leg 21 extending toward the fixed hood 111 of the fishing rod (or toward the movable hood 140) relative to the support 23 of the reel 20, and a second leg 22 extending in the opposite direction from the first leg 21 (or toward the movable hood 140).

[0032] The reel seat (100) includes a seat body (110) that is coupled to the fishing rod body (30). The seat body (110) is configured to support a pair of reel legs (21, 22).

[0033] The reel seat 100 may include a grip 113 coupled to the seat body 110. The grip 113 may be configured so that a portion of the seat body 110 is inserted into the grip 113. When the grip 113 is coupled to the seat body 110, the grip 113 may be configured so that there is no step at the boundary between the grip 113 and the seat body 110.

[0034] A fixed hood (111) and a movable hood assembly (130) secure the reel legs (21, 22) to the seat body (110). The seat body (110) includes a fixed hood (111) configured to cover a first leg (21) of the pair of reel legs (21, 22). The fixed hood (111) may be integrally formed with the seat body (110) or may be provided as a separate member from the seat body (110) and then coupled to the seat body (110).

[0035] The movable hood assembly (130) includes a movable hood (140) configured to cover the second leg (22) of the pair of reel legs (21, 22), and a nut (150) configured to move the movable hood (140) along the central axis (O) (or in the axial direction (D1)). The movable hood (140) is coupled to the seat body (110) so as to be movable in the axial direction (D1). As the movable hood (140) moves to cover the second leg (22), the second leg is fixed to the seat body (110).

[0036] In the present disclosure, the hood (111, 140) covering the reel legs (21, 22) means that the hood is positioned above at least a portion of the reel legs (21, 22) and at least a portion of the reel legs (21, 22) and at least a portion of the hood (111, 140) overlap in the vertical direction.

[0037] 2 to 4, a first gap (G1) exists under the fixed hood (111), and when the end of the first leg (21) is received in the first gap (G1), the fixed hood (111) covers the end of the first leg (21). A second gap (G2) exists between the movable hood (140) and the seat body (110), and the end of the second leg (22) is received in the second gap (G2), and the movable hood (140) covers the end of the second leg (22).

[0038] The fixed hood 111 and the movable hood 140 can cover the reel legs 21 and 22 and press the reel legs 21 and 22 downward. Referring to FIG. 2, the reel legs 21 and 22 may have inclined surfaces that become lower as they move away from the support 23, and the hoods 111 and 140 may have a shape that becomes higher toward the support 23. When the fixed hood 111 and the movable hood 140 approach each other in the axial direction D1 while contacting the inclined surfaces of the reel legs 21 and 22, the fixed hood 111 and the movable hood 140 can press the first leg 21 and the second leg 22 downward, respectively. This allows the legs (21, 22) of the reel to be tightly fitted between the seat body (110) and the hoods (111, 140), and the reel (20) to be firmly fixed to the reel seat (100).

[0039] The movable hood (140) is coupled to the seat body (110) so as to be movable in the axial direction (D1) along the central axis (O). In this disclosure, the axial direction (D1) refers to a direction aligned with the central axis (O) of the fishing rod body (30). The movable hood (140) is configured to selectively cover the other, second leg (22) of the pair of reel legs (21, 22), depending on its position on the seat body (110). For example, when the movable hood (140) approaches the fixed hood (111), it covers the second leg (22), and when the movable hood (140) moves away from the fixed hood (111), it does not cover the second leg (22).

[0040] The seat body (110) may include a guide groove (114) extending in the axial direction (D1) on its outer surface. Referring to FIG. 3, the guide groove (114) may be provided on each side of the outer surface of the seat body (110). The movable hood (140) includes a guide protrusion (146) received in the guide groove (114). The movable hood (140) may include a pair of guide protrusions (146) received in the pair of guide grooves (114), respectively. The guide protrusions (146) extend in the axial direction (D1). When the movable hood (140) is coupled to the seat body (110), the guide protrusions (146) are received in the guide groove (114), thereby limiting the movement of the movable hood (140) relative to the seat body (110) in the axial direction (D1).

[0041] The nut (150) is coupled to the movable hood (140) and configured to adjust the position of the movable hood (140) on the central axis (O). The nut (150) is configured to be movable on the seat body (110) along the central axis (O) as the nut (150) rotates around the central axis (O). The nut (150) may be threadedly coupled to the seat body (110) so as to be rotatable in the circumferential direction (D2) of the central axis (O). The seat body (110) may include, on its outer peripheral surface, a male thread (112) whose rotation axis is the central axis (O), and the nut (150) may be threadedly coupled to the male thread (112). The nut (150) may include, on its inner peripheral surface, a female thread (156) that engages with the male thread (112) of the seat body (110). Due to the interference between the male thread (112) and the female thread (156), the nut (150) can move along the central axis (O) on the seat body (110) while rotating about the central axis (O).

[0042] 3, 5, and 7, the movable hood 140 may include an annular portion 144 and a hood portion 142 extending from the annular portion 144. The annular portion 144 may have a shape that surrounds the outer circumferential surface of the seat body 110. The hood portion 142 extends in the axial direction D1 from an upper semicircular portion of the annular portion 144. Guide protrusions 146 may be disposed on both ends of the hood portion 142 in the circumferential direction D2.

[0043] 7 and 8, the annular portion 144 may include a locking groove 145 formed in the circumferential direction D2 on its inner circumferential surface. The nut 150 includes a connecting portion 152 that is connected to the movable hood 140. The connecting portion 152 may include a locking protrusion 153 that is formed in the circumferential direction D2 and is received in the locking groove 145 of the annular portion 144. When the connecting portion 152 of the nut 150 is inserted into the annular portion 144, the locking protrusion 153 is fitted into the locking groove 145, thereby rotatably connecting the nut 150 to the movable hood 140.

[0044] By rotating the nut (150) rotatably coupled to the movable hood (140), the movable hood (140) can move along the central axis (O) on the seat body (110) together with the nut (150). For example, when the nut (150) is rotated clockwise, the movable hood assembly (130) advances toward the fixed hood (111). When the nut (150) is rotated counterclockwise, the movable hood assembly (130) retreats from the fixed hood (111). In this disclosure, clockwise and counterclockwise refer to the rotational directions, respectively, when the reel seat (100) is viewed from the movable hood (140) toward the fixed hood (111) in the axial direction (D1). Furthermore, in this disclosure, the term "forward" in the axial (D1) movement of the movable hood (140), nut (150), etc. means the movement of the movable hood (140) toward the fixed hood (111), and the term "rearward" means the movement of the movable hood (140) away from the fixed hood (111).

[0045] The seat body 110 may include a protrusion 116 that is disposed below the hood portion 142 when the movable hood 140 moves toward the fixed hood 111. That is, the protrusion 116 of the seat body 110 is disposed so as to overlap the hood portion 142 of the movable hood 140 in the circumferential direction D2. When the movable hood 140 moves toward the fixed hood 111 and the hood portion 142 is partially disposed on the protrusion 116, at least a portion of the guide protrusion 146 may be covered by the protrusion 116 and not be exposed to the outside of the reel seat 100.

[0046] The movable hood 140 may include a reinforcing cover 148 that prevents deformation of the movable hood 140 and the guide protrusions 146. The reinforcing cover 148 surrounds the outside of the movable hood 140 and the guide protrusions 146. The reinforcing cover 148 may be made of a material that has higher rigidity than the material of the movable hood 140 or the guide protrusions 146. For example, the movable hood 140 and the guide protrusions 146 may be made of plastic, and the reinforcing cover 148 may be made of a metal such as aluminum or stainless steel.

[0047] Figure 8 is a side view of a nut 150 according to one embodiment. Figure 9 is a front view of a nut 150 according to one embodiment. Figure 10 is a cross-sectional view of the nut 150 of Figure 8 taken along line XX in Figure 8. Figure 11 is a cross-sectional view of the nut 150 of Figure 9 taken along line XI-XI in Figure 9.

[0048] Referring to Figure 8, the nut (150) may be provided in a generally annular shape. The nut (150) includes a connecting portion (152) and an operating portion (154) extending from the connecting portion (152). The connecting portion (152) is configured to be rotatably coupled to the movable hood (140) in the circumferential direction (D2). The operating portion (154) is a portion that is operated to rotate the nut (150). The operating portion (154) is exposed to the outside of the reel seat (100) and can be gripped by a user.

[0049] The operating portion 154 of the nut 150 may have a generally cylindrical shape. While the operating portion 154 of the nut 150 in the drawings of the present disclosure has a cylindrical shape with a constant radius along the axial direction D1, embodiments of the present disclosure are not limited thereto, and in other embodiments, the operating portion 154 of the nut 150 may have a conical shape with a varying radius along the axial direction D1.

[0050] A plurality of recesses 160 are arranged in the circumferential direction D2 in the operating portion 154 of the nut 150. Referring to Figures 7 and 8, the recesses 160 may be defined by a bottom surface 161 recessed from the outer circumferential surface 157 of the operating portion 154 toward the center of the nut 150, and side surfaces extending from the edges of the bottom surface 161.

[0051] 8 to 11, the side surfaces of the recess (160) may include a pair of first side surfaces (162a, 162b) extending from both edges of the bottom surface (161) in the circumferential direction (D2) and a pair of second side surfaces (163a, 163b) extending from both edges of the bottom surface (161) in the axial direction (D1). The pair of first side surfaces (162a, 162b) may face each other in the circumferential direction (D2), and the pair of second side surfaces (163a, 163b) may face each other in the axial direction (D1). The pair of first side surfaces (162a, 162b) may extend in the axial direction (D1), and the pair of second side surfaces (163a, 163b) may extend in the circumferential direction (D2).

[0052] The recess 160 has a shape recessed toward the central axis O when viewed from the axial direction D1. Referring to Figure 10, the recess 160 may be partially defined between two of the protruding surfaces 158 by a bottom surface 161 recessed toward the central axis O from the protruding surfaces 158, and a pair of first side surfaces 162a, 162b extending from the bottom surface 161 to the protruding surfaces 158 on both sides.

[0053] The recess 160, when viewed from the side, has a shape that is recessed toward the central axis O. Referring to Figure 11, the recess 160 may be partially defined by a bottom surface 161 that is recessed from the outer circumferential surface 157 toward the central axis O, and a pair of second side surfaces 163a, 163b that extend from the bottom surface 161 to the outer circumferential surface 157 on both sides.

[0054] 10 and 11, the side surfaces of the recess 160 may extend at an angle from the bottom surface 161. For example, the first side surfaces 162a and 162b may form an angle greater than 90° with the bottom surface 161, and the second side surfaces 163a and 163b may form an angle greater than 90° with the bottom surface 161.

[0055] Referring to Figure 8, the side of the recess (160) is provided at an angle to the bottom surface (161), so that when viewed from above, the side of the recess (160) can have a trapezoidal shape with the edge adjacent to the bottom surface as the shorter base. The trapezoid shape in this disclosure is not limited to a trapezoid according to the strict mathematical definition, but also includes a shape in which one of two bases that appear to face each other is shorter than the other, and the distance between a pair of side edges connecting both ends of the two bases increases from the shorter base to the longer base. Furthermore, the trapezoid shape in this disclosure also includes a trapezoidal shape in general, even if the sides defining the trapezoid are curved rather than straight.

[0056] 8 and 11, the lower surface (162c) of the first side surface (162a, 162b) may have a trapezoidal shape with the short base at the edge adjacent to the bottom surface (161). The second side surface (163a, 163b) may have a trapezoidal shape with the short base at the edge in contact with the bottom surface.

[0057] The side surfaces of the recess 160 may extend from the edge of the bottom surface 161 to form an obtuse angle with the bottom surface 161. The pair of first side surfaces 162a, 162b may extend such that the distance between them in the circumferential direction D2 increases as they move away from the bottom surface 161. The pair of second side surfaces 163a, 163b may extend such that the distance between them in the axial direction D1 increases as they move away from the bottom surface 161.

[0058] As the side surfaces of the recess 160 are inclined from the bottom surface 161, the contact area between the user's fingertips and the surface defining the recess 160 can be increased. This allows the user to easily apply force to the recess 160 in the circumferential direction D2 and the axial direction D1. If the side surfaces of the recess 160 were extended perpendicularly from the bottom surface 161, the contact area between the user's fingertips and the surface of the recess 160 would be smaller. Applying force to a small area would result in the fingertips being pressed with high pressure, which could cause discomfort such as pain. This would prevent the nut 150 from being rotated with sufficient force, preventing the movable hood 140 from applying sufficient pressure to the reel legs 21 and 22, which could further cause problems such as an unstable connection between the reel 20 and the reel seat 100. The recess 160 according to the embodiment of the present disclosure has its side surface inclined from the bottom surface 161, which increases the contact area between the finger and the recess 160, thereby allowing a relatively strong force to be applied comfortably to the nut 150. The nut 150 can be used to move the movable hood 140 toward the fixed hood 111 so that the movable hood 140 can sufficiently pressurize the reel legs 21, 22, thereby allowing the reel 20 to be firmly coupled to the reel seat 100.

[0059] Furthermore, the recess (160) of the nut (150) according to one embodiment of the present disclosure is recessed toward the central axis (O) even when viewed from the side, making it easy to apply a force in the axial direction (D1) to the nut (150). Applying a force in the axial direction (D1) to the nut (150) can further facilitate movement of the movable hood (140) in the axial direction (D1). For example, when rotating the nut (150) clockwise to advance the movable hood (140) toward the fixed hood (111), pushing the nut (150) toward the fixed hood (111) can more easily advance the movable hood (140). Furthermore, when rotating the nut (150) counterclockwise to retract the movable hood (140) from the fixed hood (111), pulling the nut (150) away from the fixed hood can more easily retract the movable hood (140).

[0060] The nut 150 may include a protruding surface 158 having a larger outer radius than the outer peripheral surface 157. Referring to Figure 11, the first side surfaces 162a, 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, the provision of the protruding surface 158 further increases the height of the first side surfaces 162a, 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). The first side surfaces (162a, 162b) are surfaces on which a force in the circumferential direction (D2) is applied by the fingertips, and the higher the height of the first side surfaces (162a, 162b) from the bottom surface (161), the more steadily and strongly the user can apply force to rotate the nut (150) through the fingertips. In addition, torque is determined in part by the magnitude of the product of the magnitude of the force applied to the second side surfaces (163a, 163b) and the distance from the central axis (O) to the point of application of the force. As the height of the first side surfaces (162a, 162b) increases, the point of application of the force can be moved farther from the central axis (O), and therefore, a strong torque can be applied to the nut (150) even with a relatively small force.

[0061] 7 and 8, the nut 150 may include an inclined surface 159 extending from the axial end (D1) of the protruding surface 158. The outer radius of the inclined surface 159 gradually decreases from the boundary with the protruding surface 158 toward both ends of the operating portion 154 in the axial direction (D1). The outer radius of the inclined surface 159 at both ends of the operating portion 154 in the axial direction (D1) may be the same as the outer radius of the outer surface 157. The operating portion 154 of the nut 150 contacts the movable hood 140 (or the annular portion 144 of the movable hood 140), but by disposing the inclined surface 159 between the movable hood 140 and the protruding surface 158, it is possible to eliminate or minimize any discomfort that may occur when a user grips the area between the movable hood 140 and the protruding surface 158. Furthermore, the operating portion (154) of the nut (150) contacts the lock ring (180) described below, but since the inclined surface (159) is disposed between the lock ring (180) and the protruding surface (158), any discomfort that may arise when the user grips the area between the lock ring (180) and the protruding surface (158) can be eliminated or minimized.

[0062] The recesses 160 may be arranged at regular intervals in the circumferential direction D2 of the operating portion 154. For example, five recesses 160 may be arranged at regular intervals in the circumferential direction D2 of the operating portion 154. When viewed in the axial direction D1, the angle θ1 between the pair of first side surfaces 162a, 162b, i.e., the included angle between the pair of first side surfaces 162a, 162b, may be in the range of 144° to 150°. If the included angle θ1 between the pair of first side surfaces 162a, 162b is less than 144°, as described below with reference to FIGS. 12 and 13, the mold for molding the nut 150 becomes complicated, thereby increasing the manufacturing cost of the nut 150. If the angle θ1 is greater than 150°, the recesses 160 may be slippery when pressed with a fingertip. Furthermore, if the included angle θ1 between the pair of first side surfaces 162a, 162b is greater than 150°, most of the force applied by the fingertips to the first side surfaces 162a, 162b will be directed toward the central axis O. In other words, the magnitude of the force in the circumferential direction D2 that actually rotates the nut 150 will be reduced. This may result in the nut 150 not being tightened sufficiently to secure the reel 20 firmly to the reel seat 100, or the nut 150 being tightened too much may not be easily loosened.

[0063] In the embodiment of the present disclosure, five recesses (160) are arranged in the circumferential direction (D2), but this is merely an example, and in other embodiments the number of recesses (160) may be two to four, or six or more.

[0064] When viewed in the axial direction (D1), the bottom surface (161) of the recess (160) may have an arc shape centered on the central axis (O). For example, the bottom surface (161) of the recess (160) may have a shape similar to the outer circumferential surface of a cylinder having the central axis (O) as its central axis. In this case, the ratio (R2 / R1*100) of the radius (R2) of the bottom surface (161) of the recess (160) to the outer circumferential radius (R1) of the annular portion (144) may be in the range of 90% to 93%.

[0065] The nut 150 of the present disclosure includes a plurality of recesses 160 on the outer peripheral surface 157, and the nut 150 can be easily rotated by fitting a finger into the recesses 160, thereby reducing the overall length of the nut 150 and providing a compact size. The axial length D1 of the operating portion 154 of the nut 150 can be within a range of 7 mm to 10 mm.

[0066] The outer radius of the portion of the operating portion 154 of the nut 150 adjacent to the movable hood 140 may be the same as the outer radius of the annular portion 144. The difference between the outer radius of the operating portion 154 of the nut 150 and the outer radius of the annular portion 144 may be in the range of 0 mm to 1 mm. Referring to FIG. 7, the difference (R3-R1) between the outer radius (R3) of the outer peripheral surface 157 of the nut 150 and the outer radius (R1) of the annular portion 144 may be in the range of 0 mm to 1 mm. As another example, the difference (R4-R1) between the outer radius (R4) of the protruding surface 158 of the nut 150 and the outer radius (R1) of the annular portion 144 may be in the range of 0 mm to 1 mm.

[0067] Figure 12 shows a closed die set for forming a nut 150 according to one embodiment, and Figure 13 shows the die set of Figure 12 in an open state.

[0068] 12 and 13, the nut 150 according to one embodiment can be manufactured using a mold set consisting of an upper mold M1 and a lower mold M2. The upper mold M1 and the lower mold M2 can each include cavities C1 and C2 corresponding to a portion of the shape of the nut 150.

[0069] The nut 150 may include five recesses 160 evenly spaced in the circumferential direction D2. Referring to Figure 12, the nut 150 may include a first recess 160a, a second recess 160b, a third recess 160c, a fourth recess 160d, and a fifth recess 160e arranged in counterclockwise order. The nut 150 may 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 in counterclockwise order.

[0070] The nut 150 may be formed by a mold set in such a way that the center of the second recess 160b and the center of the fifth protruding surface 158e are aligned with the V-axis. The internal cavities C1 and C2 of the upper mold M1 and the lower mold M2 may be provided symmetrically with respect to the V-axis.

[0071] The upper mold (M1) may include a cavity (C1) capable of forming the surface of the nut from a first boundary (B1) of the first recess (160a) and the first protruding surface (158a) in a counterclockwise direction to a second boundary (B2) of the third recess (160c) and the fourth protruding surface (158d). The lower mold (M2) may include a cavity (C2) capable of forming the remaining surface of the nut (150), i.e., the surface of the nut from the second boundary (B2) in a counterclockwise direction to the first boundary (B1). The H-axis is a horizontal axis connecting the first boundary (B1) and the second boundary (B2).

[0072] In each of the five recesses (160), the included angle (θ1) between the pair of first side surfaces (162a, 162b) may be in the range of 144° to 150°. When the angle between the pair of first side surfaces (162a, 162b) in the circumferential direction (D2) is 144° or more, the angle (θ2) between any surface of the nut (150) located in the first quadrant (Q1) of the four quadrants formed by the H axis and the V axis and the H axis is 90° or more. In particular, the angle between the first side surface (162a) between the bottom surface (161) of the first recess (160a) and the second protruding surface (158b) and the H axis is not an acute angle. Furthermore, the angle (θ3) between any surface of the nut (150) located in the second quadrant (Q2) and the -H axis is 90° or more. In particular, the angle formed by the first side surface 162b between the bottom surface 161 of the third recess 160c and the third protruding surface 158c with respect to the -H axis is not an acute angle. That is, the width W1 of the nut 150 formed by the upper mold M1 in the H axis direction monotonically decreases upward (i.e., toward the +V axis). Therefore, a portion of the nut 150 formed through the upper mold M1 (i.e., the portion located on the first and second quadrants Q1 and Q2 of the HV plane) can be easily separated from the upper mold M1 when the cavity C1 of the upper mold M1 is opened. If the included angle (θ1) between the pair of first side surfaces (162a, 162b) is less than 144°, the nut (150) will include a portion where the width (W1) in the H-axis direction increases upward. In this case, interference between the nut (150) and the upper die (M1) will make it difficult for the nut (150) to be separated from the upper die (M1).

[0073] When the included angle θ1 between the pair of first side surfaces 162a, 162b is 144° or more, the width W2 of the nut 150 in the H-axis direction present on the third and fourth quadrants Q3 and Q4 also monotonically decreases downward (i.e., toward the -V-axis). Therefore, a portion of the nut 150 formed through the lower mold M2 (i.e., the portion located on the third and fourth quadrants of the HV plane) can be easily separated from the lower mold M2 when the cavity C2 of the lower mold M2 is opened.

[0074] When the included angle θ1 between the pair of first side surfaces 162a, 162b is 144° or more, the nut 150 can be formed using a mold set with a simple structure as shown in Figures 12 and 13. This improves the precision of the mold and reduces the costs of manufacturing and maintaining the mold.

[0075] Figure 14 shows the operation of rotating the nut (150) with a finger to move the movable hood (140) toward the fixed hood (111). Figure 15 shows the operation of rotating the nut (150) with a finger to move the movable hood (140) back from the fixed hood (111). Figure 16 shows the state when the reel seat (100) according to one embodiment is gripped.

[0076] Referring to Figure 14, a user can position the tips of their index finger (F2) and thumb (F1) in the recesses 160 and rotate the nut 150 clockwise about the central axis (O) to advance the movable hood 140. Referring to Figure 15, a user can position the tips of their index finger (F2) and thumb (F1) in the recesses 160 and rotate the nut 150 counterclockwise about the central axis (O) to retract the movable hood 140.

[0077] When the fingertips are accommodated in the recesses (160), the first side surfaces (162a, 162b) of the recesses (160) prevent the fingertips from slipping in the circumferential direction (D2) or the axial direction (D1), allowing for easy and stable application of circumferential (D2) and axial (D1) forces to the nut (150). The user can easily rotate the nut (150) by using their fingertips to apply circumferential (D2) force to the first side surfaces (162a, 162b) of the recesses (160).

[0078] The recess 160 of the nut 150 has second side surfaces 163a, 163b that can receive axial force D1, allowing the user to rotate the nut 150 by pushing or pulling the second side surfaces 163a, 163b. That is, the user can simultaneously apply circumferential force D2 and axial force D1 to the nut 150 using their fingers. Because the nut 150 is threadedly coupled to the seat body 110, it moves in the axial direction D1 when rotated clockwise. Therefore, when the user rotates the nut 150 with their fingers, it is advantageous to push or pull the nut 150 in the axial direction D1. Furthermore, when the nut 150 is rotated, the user's fingertips also move in the axial direction D1 while being accommodated in the recess 160 of the nut 150, so it is more natural to push or pull the nut 150 in the axial direction D1 when rotating the nut 150. According to the embodiment of the present disclosure, the user can push or pull the nut 150 while rotating it, thereby eliminating or minimizing the stress felt by the user when rotating the nut 150.

[0079] 16, the recess 160 is recessed toward the central axis O of the nut 150 rather than the outer circumferential surface 157 or the protruding surface 158, so that when fishing, the fingertips or pads can be placed on the outer circumferential surface 157 or the protruding surface 158 of the nut 150, excluding the recess 160. This prevents the nut 150 from being unintentionally turned by the fingers while fishing.

[0080] Figure 17 shows a movable hood assembly 230 according to one embodiment. Figure 18 is a front view of the nut 250 of Figure 17. Figure 19 shows the nut 250 of Figure 17 in a gripped state.

[0081] Referring to Figures 17 and 18, the nut 250 may include a knurling portion 258 disposed between adjacent recesses 160 among the multiple recesses 160. The knurling portion 258 may include multiple 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 be radially convex or pointed. A groove 258b extending in the axial direction D1 is disposed between adjacent ridges 258a. The knurling portion 258 in Figures 17 and 18 includes three ridges 258a, but this is merely an example, and the number of ridges 258a may be two or four or more.

[0082] 19, the nut 250 includes a knurled portion 258, so that when the index finger F2 and thumb F1 surround the operating portion 154, the friction between the fingers and the operating portion 154 is increased and the nut 250 does not slip. This allows the nut 250 to be turned with greater force. Furthermore, when gripping the nut, positioning the tips of the fingers in the recesses 160 further increases the friction between the hand and the nut 250.

[0083] Figure 20 shows the process of assembling the lock nut assembly 170 to the seat body 110 in one embodiment. Figure 21 shows the state in which the lock nut assembly 170 is coupled to the seat body 110 in one embodiment. Figure 22 shows the process of coupling a lock ring 180 to a lock nut 190 in one embodiment. Figure 23 is a side view of the process of assembling the lock nut assembly 170 to the seat body 110 in one embodiment. Figure 24 is a cross-sectional view of the movable hood assembly 130 and lock nut assembly 170 in Figure 21 taken along line XXIV-XXIV in Figure 21.

[0084] 20 and 21, the reel seat 100 may further include a lock nut assembly 170. The lock nut assembly 170 is coupled to the seat body 110 and disposed on one side of the movable hood assembly 130. The lock nut assembly 170 is configured to prevent the nut 150 from loosening.

[0085] The lock nut assembly 170 includes a lock ring 180 and a lock nut 190. The lock ring 180 is disposed on one side of the nut 150 and is connected to the seat body 110 so as to be movable in the axial direction D1. Referring to Figure 22, the lock ring 180 is connected to the lock nut 190, and the assembly of the lock ring 180 and the lock nut 190, i.e., the lock nut assembly 170, is connected to the seat body 110.

[0086] The lock ring 180 is coupled to the lock nut 190 so as to be rotatable in the circumferential direction D2. Referring to Figures 22 and 24, the lock ring 180 may include a locking protrusion 182 extending in the circumferential direction D2, and the lock nut 190 may include a locking groove 192 configured to receive the locking protrusion 182 of the lock ring 180. The lock ring 180 is coupled to the seat body 110 so as to be movably in the axial direction D1. Referring to Figure 24, the lock ring 180 may include a guide protrusion 184 on its inner circumferential surface that is received in the guide groove 114 of the seat body 110. The guide protrusion 184 of the lock ring 180 may extend in the axial direction D1.

[0087] The lock nut 190 is threadedly coupled to the seat body 110 so as to be rotatable in the circumferential direction D2. The lock nut 190 may include an internal thread 194 on its inner circumferential surface that is threadedly coupled to the external thread 112 formed on the outer circumferential surface of the seat body 110. Referring to Figure 20, after being fitted to the seat body 110, the lock nut 190 can be rotated clockwise to advance in the axial direction D1 along the external thread 112 of the seat body 110.

[0088] The lock ring (180) may include an insert portion (185) extending in a direction toward the nut (150). The insert portion (185) is configured to be inserted into the nut (150). The nut (150) includes a receiving portion (155) configured to receive the insert portion (185). The insert portion (185) has an outer circumferential radius smaller than the outer circumferential radius (R5) of the lock ring (180), and when inserted into the receiving portion (155) of the nut (150), the nut (150) surrounds the insert portion (185) in the circumferential direction (D2).

[0089] When the lock nut (190) rotates around the central axis (O), the lock nut (190) moves in the axial direction (D1), which causes the lock ring (180) to also move in the axial direction (D1). Because the guide protrusions (184) of the lock ring (180) move along the guide grooves (114), the lock ring (180) moves only in the axial direction (D1) without rotating.

[0090] 23 and 24, by rotating the lock nut 190 clockwise, the front surface 181 of the lock ring 180 can be brought into contact with the rear surface 151 of the nut 150. Turning the lock nut 190 forcefully causes the lock ring 180 to press the rear surface 151 of the nut 150 firmly toward the movable hood 140. For the nut 150 to loosen, it must be able to move rearward (i.e., away from the fixed hood 111). However, with the lock ring 180 pressing against the nut 150, the nut 150 cannot move rearward. Therefore, by pressing the nut 150 with the lock ring 180, it is possible to prevent the nut 150 from loosening from the seat body 110.

[0091] The outer radius of the portion of the operating portion 154 of the nut 150 adjacent to the lock ring 180 may be the same as the outer radius of the lock ring 180. The difference between the outer radius of the operating portion 154 of the nut 150 and the outer radius of the lock ring 180 may be within a range of 0 mm to 1 mm. The difference (R3-R5) between the outer radius (R3) of the outer peripheral surface 157 of the nut 150 and the outer radius (R5) of the lock ring 180 may be within a 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 lock ring 180 may be within a range of 0 mm to 1 mm.

[0092] FIG. 25 illustrates the operation of moving the movable hood 140 toward the fixed hood 111 with the lock nut assembly 170 coupled to the seat body 110. FIG. 26 illustrates the operation of retracting the movable hood 140 from the fixed hood 111 with the lock nut assembly 170 coupled to the seat body 110. Referring to FIGS. 25 and 26, the nut 150 can be easily rotated even with the lock nut assembly 170 attached to the seat body 110. A user can rotate the nut 150 by placing only the tip of a finger in the recess 160 of the nut 150 and applying force in the circumferential direction (D2) to the nut 150. This allows the force of the finger to be concentrated in the recess 160 of the nut 150, allowing the user to easily rotate the nut 150 without any discomfort, even when the lock nut assembly 170 is close to the nut 150.

[0093] FIG. 27 shows a fishing rod according to one embodiment. FIG. 28 shows a fishing rod (10') according to another embodiment. The fishing rods (10, 10') may include the reel seat (100) of the present disclosure. Referring to FIG. 27, the fixed hood (111) and the movable hood assembly (130) may be arranged in a direction from the tip of the fishing rod toward the rear grip (40). Referring to FIG. 28, the movable hood assembly (130) and the fixed hood (111) may be arranged in a direction from the tip of the fishing rod (10') toward the rear grip (40).

[0094] Figure 29, referring to Figure 27, shows a fishing rod with a lock nut assembly 170 attached to one side of a movable hood assembly 230 according to one embodiment. Figure 30, referring to Figure 28, shows a fishing rod with a lock nut assembly 170 attached to one side of a movable hood assembly 230 according to one embodiment.
