Description

Technical Field

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

[0002] In a fishing rod using a fishing reel, in order to mount the fishing reel on the fishing rod, a reel seat is mounted on a rod body. The reel seat has a fixed cover for fixing one reel leg of the fishing reel to the reel seat body, and the rod body of the fishing rod is inserted and passed through the reel seat body. The reel seat also has a convex thread, and the convex thread has a certain length in a direction opposite to the fixed cover and in which the other reel leg of the fishing reel is fixed. The reel seat includes a movable cover, and the movable cover can be moved in the axial direction of the fishing rod by rotating a nut threadedly connected to the convex thread. The movable cover and the fixed cover fixedly support the reel legs, thereby fixing the fishing reel.

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

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

[0005] In the conventional nut 6 of the reel seat 3, in order to prevent the nut 6 from rotating during fishing, the cover side portion 6a should be provided with a relatively long length. In addition, in order to facilitate the rotation of the nut 6, the opposite cover side portion 6b should be provided with a relatively long length. Therefore, the conventional nut 6 has a limitation in providing a compact or light-weight nut. Summary of the invention

[0061] Figure 2 1 is a view showing a reel seat 100 according to one embodiment. Figure 31 is a view showing a process of assembling the movable cover assembly 130 to the seat body 110 in one embodiment. Figure 4 1 is a view showing a state in which the movable cover assembly 130 is assembled to the seat body 110 in one embodiment. Figure 5 1 is a view showing the connection of the nut 150 and the movable cover 140 in one embodiment. Figure 6 1 is a side view showing a process of assembling the movable cover 140 to the seat body 110 in one embodiment. Figure 7 yes Figure 4 The movable cover assembly 130 is along Figure 4 Cross-sectional view along line VII-VII.

[0062] refer to Figure 2 , the reel seat 100 is configured to fix the reel 20 to the fishing rod. The reel 20 includes a support member 23 extending toward the reel seat 100 and a pair of reel legs 21 and 22 extending from the lower end of the support member 23 in opposite directions to each other in the axial direction D1. The pair of reel legs 21 and 22 are coupled to the reel seat 100, thereby fixing the reel 20 to the fishing rod. The pair of reel legs 21 and 22 include a first leg 21 and a second leg 22, the first leg 21 extending toward the fixed cover 111 of the fishing rod relative to the support member 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 seat 100 includes a seat body 110 coupled to the shaft body 30. The seat body 110 is configured to support a pair of reel legs 21 and 22.

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

[0065] The fixed cover 111 and the movable cover assembly 130 fix the reel legs 21 and 22 to the seat body 110. The seat body 110 includes the fixed cover 111 configured to cover the first leg 21 of the pair of reel legs 21 and 22. The fixed cover 111 may be formed integrally with the seat body 110, or may be coupled to the seat body 110 after being provided as a member separate from the seat body 110.

[0066] The movable cover assembly 130 includes a movable cover 140 configured to cover the second leg 22 of the pair of reel legs 21 and 22, and a nut 150 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 seat body 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 seat body 110.

[0067] In the present disclosure, the description that the covers 111 and 140 cover the reel legs 21 and 22 means that the covers are provided on at least a portion of the reel legs 21 and 22, and at least a portion of the reel legs 21 and 22 and at least a portion of the covers 111 and 140 overlap each other 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 body 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 may press the reel legs 21 and 22 downward while covering the reel legs 21 and 22. Figure 2 , the reel legs 21 and 22 may have an inclined surface that gradually descends in a direction away from the support member 23, and the covers 111 and 140 may have a shape that gradually rises toward the support member 23. When the fixed cover 111 and the movable cover 140 approach each other in the axial direction D1 while contacting the inclined surfaces of the reel legs 21 and 22, the fixed cover 111 and the movable cover 140 may respectively press the first leg 21 and the second leg 22 downward. Therefore, the reel legs 21 and 22 may be tightly fitted between the seat body 110 and the covers 111 and 140, and the reel 20 may be firmly fixed to the reel seat 100.

[0070] The movable cover 140 is coupled to the seat body 110 so as to be movable along the central axis O in an axial direction D1. In the present disclosure, the axial direction D1 refers to a direction parallel to the central axis O of the rod body 30. The movable cover 140 is configured to selectively cover the second leg 22, which is the other of the pair of reel legs 21 and 22, according to the position of the movable cover on the seat body 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 body 110 may include a guide groove 114 extending along the axial direction D1 on its outer surface. Figure 3 , the guide groove 114 may be provided on each lateral side of the outer surface of the seat body 110. The movable cover 140 includes a guide protrusion 146 accommodated in the guide groove 114. The movable cover 140 may include a pair of guide protrusions 146 accommodated in the pair of guide grooves 114, respectively. The guide protrusion 146 extends in the axial direction D1. When the movable cover 140 is coupled to the seat body 110, the guide protrusion 146 is accommodated in the guide groove 114, and thus, the movement of the movable cover 140 relative to the seat body 110 is limited to the axial direction D1.

[0072] The nut 150 is coupled to the movable cover 140 and is configured to adjust the position of the movable cover 140 along the central axis O. The nut 150 is configured to move along the central axis O on the seat body 110 by its rotation 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 includes a male thread 112 having a rotation axis on the central axis O on its outer peripheral surface, and the nut 150 may be threadedly coupled to the male thread 112. The nut 150 may include a female thread 156 on its inner peripheral surface that engages with the male thread 112 of the seat body 110. Due to the interaction of the male thread 112 and the female thread 156, the nut 150 may move along the central axis O on the seat body 110 while rotating around the 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 body 110. The cover portion 142 extends from an upper semicircle of the annular portion 144 in the axial direction D1. A guide protrusion 146 may be provided at each of both ends of the hood portion 142 in the circumferential direction D2.

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

[0075] By the rotation of the nut 150 rotatably coupled to the movable cover 140, the movable cover 140 can be moved on the seat body 110 along the central axis O together with the nut 150. For example, when the nut 150 is rotated in the clockwise direction, the movable cover assembly 130 advances toward the fixed cover 111. When the nut 150 is rotated in the counterclockwise direction, the movable cover assembly 130 retracts from the fixed cover 111. In the present disclosure, the clockwise direction and the counterclockwise direction respectively refer to the clockwise rotation direction and the counterclockwise rotation direction when the reel seat 100 is observed from the movable cover 140 toward the fixed cover 111 along the axial direction D1. In addition, in the present disclosure, the term "advancement" with respect to the movement of the movable cover 140, the nut 150, etc. in the axial direction D1 refers to the movement in the direction in which the movable cover 140 moves toward the fixed cover 111, and the term "retraction" refers to the movement in the direction in which the movable cover 140 moves away from the fixed cover 111.

[0076] The seat body 110 may include a protruding portion 116, and when the movable cover 140 moves toward the fixed cover 111, the protruding portion 116 is disposed below the cover portion 142. That is, the protruding portion 116 of the seat body 110 is disposed 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 disposed above the protruding portion 116, at least a portion of the guide protrusion 146 is covered by the protruding portion 116 and may not be exposed to the outside of the reel seat 100.

[0077] The movable cover 140 may include a reinforcement cover 148 that prevents deformation of the movable cover 140 and the guide protrusion 146. The reinforcement cover 148 surrounds the outside of the movable cover 140 and the guide protrusion 146. The reinforcement cover 148 may be made of a material having higher rigidity than that 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 reinforcement cover 148 may be made of a metal such as aluminum or stainless steel.

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

[0079] Reference Figure 8, the nut 150 may be provided in a substantially annular shape. The nut 150 includes a connecting portion 152 and a manipulation portion 154 extending from the connecting portion 152. The connecting portion 152 is configured to be coupled to the movable cover 140 so as to be rotatable in the circumferential direction D2. The manipulation portion 154 is a portion manipulated to rotate the nut 150. The manipulation portion 154 is exposed to the outside of the reel seat 100 and may be grasped by a user.

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

[0081] A plurality of recessed portions 160 are provided in the manipulation portion 154 of the nut 150 in the circumferential direction D2. Figure 7 and Figure 8 Each of the recessed portions 160 may be defined by a bottom surface 161 that is recessed from the outer peripheral surface 157 of the manipulation portion 154 toward the center of the nut 150 , and a side surface that extends from an edge of the bottom surface 161 .

[0082] Reference Figures 8 to 11 , the side surface of the recessed portion 160 may include a pair of first side surfaces 162a and 162b extending from two edges of the bottom surface 161 in the circumferential direction D2, respectively, and a pair of second side surfaces 163a and 163b extending from two edges of the bottom surface 161 in the axial direction D1, respectively. 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 in the axial direction D1, the concave portion 160 has a shape that is concave in a direction toward the central axis O. Fig.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 surface 158 toward the central axis O between two protruding surfaces 158 among 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 a side view, the concave portion 160 has a shape that is concave in a direction toward the central axis O. Fig.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 Fig.10 and Fig.11 , the side surface of the concave portion 160 may extend obliquely from the bottom surface 161. For example, the first side surfaces 162a and 162b may form an angle greater than 90 degrees with the bottom surface 161, and the second side surfaces 163a and 163b may form an angle greater than 90 degrees with the bottom surface 161.

[0086] Reference Figure 8 , since the side surface of the recessed portion 160 is arranged obliquely relative to the bottom surface 161, when the recessed portion 160 is observed from above, each side surface of the recessed portion 160 may have a trapezoidal shape having an edge of the adjacent bottom surface as a short bottom. The trapezoidal shape in the present disclosure is not limited to a trapezoid defined by a strict mathematical definition. The trapezoidal shape may include a shape in which one of the two bottoms positioned opposite to each other is shorter than the other of them in appearance, and the distance between a pair of inclined edges at both ends of each of the two bottoms interconnected each other gradually increases from the short bottom toward the long bottom. In addition, the trapezoidal shape of the present disclosure may include an approximate trapezoidal shape in which the sides defining the trapezoid are not straight lines but curves.

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

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

[0089] Since the side surface of the recessed portion 160 is inclined from the bottom surface 161, the contact area between the user's fingertips and the surface defining the recessed portion 160 can be increased. Therefore, it is easy to apply force to the recessed portion 160 in the circumferential direction D2 and the axial direction D1 by the fingertips. In the case where the side surface of the recessed portion 160 extends vertically from the bottom surface 161, the contact area between the fingertips in contact with each other and the surface of the recessed portion 160 will be reduced, and the fingertips applying force to the small contact area will be pressed with high pressure, and discomfort such as pain may be caused to the fingertips. As a result, the nut 150 cannot be rotated with a strong force, and the movable cover 140 cannot press the reel legs 21 and 22 with sufficient force. Therefore, there may be a problem that the connection between the reel 20 and the reel seat 100 becomes unstable. In the recessed portion 160 according to one embodiment of the present disclosure, the side surface of the recessed portion is formed to be inclined from the bottom surface 161. Therefore, the contact area between the finger and the recessed portion 160 increases, and therefore, 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 reel legs 21 and 22, and this enables the reel 20 to be firmly coupled to the reel 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 advances toward the fixed cover 111 by the rotation of the nut 150 in the clockwise direction, pushing the nut 150 toward the fixed cover 111 can more easily advance the movable cover 140. Furthermore, when the movable cover 140 is retracted from the fixed cover 111 by the rotation of the nut 150 in the counterclockwise direction, 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 peripheral radius than the outer peripheral surface 157. Fig.11, each of the first side surfaces 162a and 162b may include a lower surface 162c extending from the bottom surface 161 up 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, since the protruding surface 158 is provided, 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 to which a force in the circumferential direction D2 is applied 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 stably and strongly apply a force to rotate the nut 150 by the fingertip. In addition, the torque may be partially determined by the size of the product of the size of the force applied to the second side surfaces 163a and 163b and the distance from the central axis O to the application point. As the heights of the first side surfaces 162 a and 162 b become higher, the force application point may be moved away from the central axis O, and thus, a strong torque may 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 from an end of the protruding surface 158 in the axial direction D1. 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 manipulation portion 154 in the axial direction D1. At either end of the manipulation 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 manipulation 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 provided between the movable cover 140 and the protruding surface 158, the inconvenience that occurs when the user grips the area between the movable cover 140 and the protruding surface 158 can be eliminated or minimized. In addition, the manipulation portion 154 of the nut 150 contacts the locking ring 180, which will be described later. Since the inclined surface 159 is provided between the locking ring 180 and the protruding surface 158 , it is possible to eliminate or minimize inconvenience that occurs when a user grips an area between the locking ring 180 and the protruding surface 158 .

[0093] A plurality of recessed portions 160 may be provided at equal intervals in the circumferential direction D2 of the manipulation portion 154. For example, five recessed portions 160 may be provided at equal intervals in the circumferential direction D2 of the manipulation portion 154. When viewed in the axial direction D1, an angle θ1 formed by the pair of first side surfaces 162a and 162b (i.e., an included angle of the pair of first side surfaces 162a and 162b) may be in the range of 144 degrees to 150 degrees. In the case where the included angle θ1 of the pair of first side surfaces 162a and 162b is less than 144 degrees, there may be a problem that a metal mold for molding the nut 150 becomes complicated, as will be described later. Fig.12 and 13 As described above, the manufacturing cost of the nut 150 is increased. In the case where the angle θ1 is greater than 150 degrees, there may be a problem that the fingertip easily slips when the fingertip pushes the recessed portion 160. In addition, in the case where the angle θ1 of the pair of first side surfaces 162a and 162b is greater than 150 degrees, most of the force of the fingertip pushing the first side surfaces 162a and 162b is directed toward the central axis O. In other words, with respect to the thrust, the magnitude of the force in the circumferential direction D2 that actually rotates the nut 150 is reduced. Therefore, although the nut 150 is firmly tightened, the reel 20 cannot be firmly fixed to the reel seat 100, and on the other hand, the firmly tightened nut 150 cannot be easily loosened.

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

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

[0096] The nut 150 of the present disclosure includes a plurality of recessed portions 160 in the outer peripheral surface 157, and the nut 150 can be easily rotated by engaging the recessed portions 160 with the fingertips. 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 manipulation 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 circumferential radius of the portion of the manipulation portion 154 of the nut 150 adjacent to the movable cover 140 may be equal to the outer circumferential radius of the annular portion 144. The difference between the outer circumferential radius of the manipulation portion 154 of the nut 150 and the outer circumferential radius of the annular portion 144 may be in the range of 0 mm to 1 mm. 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 may 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 may be in the range of 0 mm to 1 mm.

[0098] Fig.12 1 is a view showing a closed state of a metal die set for forming a nut 150 according to one embodiment. Fig.13 It is shown Fig.12 View of the metal mold set in the opened state.

[0099] Reference Fig.12 and Fig.13 The nut 150 according to one embodiment may be manufactured using a metal mold set consisting of an upper mold M1 and a lower mold M2 . The upper mold M1 and the lower mold M2 may include cavities C1 and C2 corresponding to a partial shape of the nut 150 , respectively.

[0100] The nut 150 may include five recessed portions 160 disposed at equal intervals in the circumferential direction D2. Fig.12 The nut 150 may include a first concave portion 160a, a second concave portion 160b, a third concave portion 160c, a fourth concave portion 160d, and a fifth concave portion 160e sequentially arranged in a counterclockwise direction. 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 sequentially arranged in a counterclockwise direction.

[0101] The nut 150 may be formed by a metal mold set such that the center of the second concave portion 160b and the center of the fifth protruding surface 158e are aligned on the V axis. The inner cavities C1 and C2 of the upper and lower molds M1 and M2 may be disposed in a symmetrical form about the V axis.

[0102] The upper mold M1 may include a cavity C1 that may form a surface of the nut from a first boundary B1 between the first concave portion 160a and the first protruding surface 158a to a second boundary B2 between the third concave portion 160c and the fourth protruding surface 158d in a counterclockwise direction. The lower mold M2 may include a cavity C2 that may form the remaining surface of the nut 150, that is, the surface of the nut from the second boundary B2 to the first boundary B1 in a counterclockwise direction. The H axis is a horizontal axis interconnecting the first boundary B1 and the second boundary B2.

[0103] The angle θ1 of a pair of first side surfaces 162a and 162b in each of the five concave portions 160 may be in the range of 144 to 150 degrees. In the case where the angle between the pair of first side surfaces 162a and 162b facing each other in the circumferential direction D2 is 144 degrees or more, in the four quadrants formed by the H-axis and the V-axis, the angle θ2 formed by any surface of the nut 150 existing in the first quadrant Q1 and the H-axis is 90 degrees or more. In particular, the angle formed by the first side surface 162a between the bottom surface 161 of the first concave portion 160a and the second protruding surface 158b and the H-axis is not an acute angle. In addition, the angle θ3 formed by any surface of the nut 150 existing in the second quadrant Q2 and the negative H-axis is 90 degrees or more. In particular, the angle formed by the first side surface 162a between the bottom surface 161 of the third concave portion 160a and the third protruding surface 158c and the negative H-axis is not an acute angle. That is, in the nut 150 formed by the upper mold M1, the width W1 in the H-axis direction decreases monotonically upward (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. In the case where the angle θ1 between 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 upward. 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] In the case where the angle θ1 between the pair of first side surfaces 162a and 162b is 144 degrees or more, 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 direction). 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 quadrant and the fourth quadrant in the HV plane) can be easily separated from the lower mold M2.

[0105] In the case where the angle θ1 of the pair of first side surfaces 162a and 162b is 144 degrees or more, a lens having the following characteristics may be used. Fig.12 and Fig.13 The metal mold set of the simple structure shown is used to form the nut 150. This can improve the accuracy of the metal mold and save the cost of manufacturing and maintaining the metal mold.

[0106] Fig.14 1 is a view showing a motion of rotating the nut 150 by fingertips to move the movable cover 140 toward the fixed cover 111 . Fig.15 1 is a view showing a motion of rotating the nut 150 by fingertips to retract the movable cover 140 from the fixed cover 111 . Fig.16 1 is a view showing a state in which the reel seat 100 according to one embodiment is gripped.

[0107] Reference Fig.14 , the user positions the fingertips of the index finger F2 and the thumb F1 in the recessed portion 160 and rotates the nut 150 in the clockwise direction around the central axis O, whereby the movable cover 140 can be advanced. Fig.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 in the counterclockwise direction around the central axis O, whereby the movable cover 140 can be retracted.

[0108] When the fingertip is received in the concave portion 160, the first side surfaces 162a and 162b of the concave portion 160 prevent the fingertip from sliding in the circumferential direction D2 or the axial direction D1. Therefore, the force in the circumferential direction D2 and the force in 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 concave portion 160 in the circumferential direction D2 with the fingertip.

[0109] The recessed portion 160 of the nut 150 has second side surfaces 163a and 163b that can receive a force in the axial direction D1. Therefore, the user can rotate the nut 150 while pushing or pulling the second side surfaces 163a and 163b. That is, the user can apply a force in the circumferential direction D2 and a force in the axial direction D1 to the nut 150 at the same time through the fingertips. The nut 150 is threadedly coupled to the seat body 110, and when rotated in the clockwise direction, the nut 150 moves in the axial direction D1. Therefore, when the user rotates the nut 150 through the fingertips, pushing or pulling the nut 150 in the axial direction D1 facilitates the rotation of the nut 150. In addition, when the nut 150 rotates, the user's fingertips also move in the axial direction D1 while being accommodated in the recessed portion 160 of the nut 150. Therefore, when the nut 150 rotates, it is more comfortable to push or pull the nut 150 in the axial direction D1. According to one embodiment of the present disclosure, since the user may push or pull the nut 150 while rotating the nut 150 , the pressure felt by the user when rotating the nut 150 may be eliminated or minimized.

[0110] Reference Fig.16 , the recessed portion 160 is recessed toward the central axis O compared to the outer peripheral surface 157 or the protruding surface 158 of the nut 150. Therefore, during fishing, the fingertip or the inner surface of the finger can be placed on the outer peripheral surface 157 or the protruding surface 158 of the nut 150 except for the recessed portion 160. Therefore, the nut 150 can be prevented from being unintentionally rotated by the finger during fishing.

[0111] Fig.17 is a view showing a movable cover assembly 230 according to one embodiment. Fig.18 yes Fig.17 Front view of nut 250. Fig.19 It is shown Fig.17 FIG. 2 is a view of a state in which the nut 250 is gripped.

[0112] Reference Fig.17 and Fig.18 The nut 250 may include a knurled portion 258 disposed between adjacent recessed portions 160 among the plurality of recessed portions 160. The knurled portion 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 radial convex shape. A groove 258b extending in the axial direction D1 is disposed between adjacent ridges 258a. Fig.17 and 18 In the embodiment, the knurled portion 258 includes three ridges 258a, but this is only exemplary. The number of ridges 258a may be two or four or more.

[0113] refer to Fig.19 Since the nut 250 includes the knurled portion 258, when the index finger F2 and the thumb F1 surround the manipulation portion 154, the friction between the fingers and the manipulation portion 154 is further increased, and the fingers do not slip. Therefore, the nut 250 can be turned with a stronger force by hand. In addition, when the fingertips are positioned in the concave portion 160 during gripping, the friction between the hand and the nut 250 can be further increased.

[0114] Fig. 20 1 is a view showing a process of assembling the locking nut assembly 170 to the seat body 110 in one embodiment. Fig.21 1 is a view showing a state in which the locking nut assembly 170 is coupled to the seat body 110 in one embodiment. Fig. 22 1 is a view illustrating a process of coupling the locking ring 180 to the locking nut 190 in one embodiment. Fig.23 FIG. 1 is a side view showing a process of assembling the locking nut assembly 170 to the seat body 110 in one embodiment. Fig.24 yes Fig.21 The movable cover assembly 130 and the locking nut assembly 170 are arranged along Fig.21 A cross-sectional view along line XXIV-XXIV.

[0115] Reference Fig. 20 and Fig.21 , the reel seat 100 may further include a locking nut assembly 170. The locking nut assembly 170 is coupled to the seat body 110 and is 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 is coupled to the seat body 110 so as to be movable in the axial direction D1. Fig. 22 The locking ring 180 is coupled to the locking nut 190 , and an assembly of the locking ring 180 and the locking nut 190 (ie, the locking nut assembly 170 ) is coupled to the seat body 110 .

[0117] The locking ring 180 is coupled to the locking nut 190 so as to be rotatable in the circumferential direction D2. Fig. 22 and Fig.24 , the locking ring 180 may include an engagement protrusion 182 extending in the circumferential direction D2, and the locking nut 190 may include an engagement groove 192 configured to receive the engagement protrusion 182 of the locking ring 180. The locking ring 180 is coupled to the seat body 110 so as to be movable in the axial direction D1. Fig.24The locking ring 180 may include, on its inner circumferential surface, a guide protrusion 184 received in the guide groove 114 of the seat body. The guide protrusion 184 of the locking ring 180 may extend in the axial direction D1.

[0118] The locking nut 190 is threadedly coupled to the seat body 110 so as to be rotatable in the circumferential direction D2. The locking nut 190 may include a female thread 194 on its inner circumferential surface, which is threadedly coupled to the male thread 112 formed on the outer circumferential surface of the seat body 110. Fig. 20 When the locking nut 190 is assembled on the seat body 110 and rotated in a clockwise direction, the locking nut can move forward in the axial direction D1 along the convex thread 112 of the seat body 110 .

[0119] The locking ring 180 may include an insertion portion 185 extending in a direction 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 in the axial direction D1 accordingly. 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 without rotating.

[0121] Reference Fig.23 and Fig.24 , when the locking nut 190 is rotated in the clockwise direction, the front surface 181 of the locking ring 180 may contact the rear surface 151 of the nut 150. When the locking nut 190 is turned strongly, the locking ring 180 may strongly push the rear surface 151 of the nut 150 toward the movable cover 140. In order to loosen the nut 150, the nut 150 needs to move backward (i.e., in a direction away from the fixed cover 111). However, in a state where the locking ring 180 pushes 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 body 110.

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

[0123] Fig.25 1 is a view showing a movement of moving the movable cover 140 toward the fixed cover 111 in a state where the locking nut assembly 170 is coupled to the seat body 110 . Fig.26 1 is a view showing a movement of retracting the movable cover 140 from the fixed cover 111 in a state where the locking nut assembly 170 is coupled to the seat body 110. Fig.25 and 26 , the nut 150 can be easily rotated even in a state where the locking nut assembly 170 is assembled to the seat body 110. The user can rotate the nut 150 only with the help of the fingertips by inserting the 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 to the recessed portion 160 of the nut 150, the user can easily rotate the nut 150 without inconvenience even if the locking nut assembly 170 is close to the nut 150.

[0124] Fig. 27 is a view showing a fishing rod according to one embodiment. Fig.28 1 is a view showing a fishing rod 10' according to another embodiment. The fishing rods 10 and 10' may include the reel seat 100 of the present disclosure. Fig. 27 , the fixed cover 111 and the movable cover assembly 130 may be arranged in a direction from the tip of the fishing rod toward the rear grip 40. Fig.28 , the movable cover assembly 130 and the fixed cover 111 may be arranged in a direction from the tip of the fishing rod 10 ′ toward the rear grip 40 .

[0126] So far, the technical concept of the present 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 changes can be made without departing from the technical concept and scope of the present disclosure that can be understood by a person of ordinary skill in the art to which the present disclosure belongs. In addition, it should be understood that such substitutions, modifications and changes fall within the scope of the attached claims.
