Abstract
Description
Technical Field
[0001] This invention relates to a fishing reel equipped with a one-way clutch. Background Technology
[0002] Traditionally, spinning reels for fishing include a reverse-rotation prevention mechanism. This mechanism allows the rotor to rotate in the line winding direction by rotating the handle, and prevents the rotor from rotating when the handle is reversed. Typically, the reverse-rotation prevention mechanism consists of a one-way clutch comprising: an inner ring that engages with a pinion to prevent rotation; a retainer located radially outward of the inner ring to hold multiple rolling components; and an outer ring located radially outward of the retainer and fixed to the reel body to prevent rotation.
[0003] As a fishing reel equipped with such a one-way clutch, Patent Document 1 discloses a fishing reel incorporating a one-way clutch. This one-way clutch allows rotation in one direction of a rotary drive shaft supported within the reel body and prevents rotation in the other direction. The one-way clutch is characterized by having an assembly structure comprising: an inner ring; an outer ring; a first retainer having a retaining portion for retaining a force-applying spring that applies force to multiple rolling components; and a second retainer mounted on the first retainer to clamp the outer ring axially. A fixing portion is provided on the reel body to restrict the rotational movement of the one-way clutch. Protrusions extending radially outward are formed on the first retainer and the outer ring, respectively. The rotational movement of the one-way clutch is restricted by the fixing portion of the reel body and the protrusions.

Detailed Implementation
[0020] Hereinafter, embodiments of the fishing reel according to the present invention will be specifically described with reference to the accompanying drawings. In the various drawings, common components are labeled with the same reference numerals throughout. For ease of explanation, the drawings are not necessarily described to an exact scale; this should be noted.
[0021] First, refer to Figure 1 , Figure 2 The overall configuration of a fishing reel according to one embodiment of the present invention will be described. Figure 1 This is an exploded perspective view of a fishing reel according to one embodiment of the present invention. Figure 2 This is a cross-sectional view illustrating an embodiment of a fishing reel according to the present invention. Furthermore, in the following description of the one-way clutch, the direction that will become the drum side is defined as front (upper side), the direction that will become the reel body side is defined as rear (lower side), the axial direction X is defined as the axis of the drum shaft, and the center O is defined as the axis position of the drum shaft (see reference). Figure 2 ).
[0022] One embodiment of the present invention relates to a fishing reel, which is a spinning reel (hereinafter referred to as a fishing reel) 1. A reel foot 2A, which is mounted on a fishing rod, is integrally formed on the reel body 2. At the front of the reel body 2 are: a rotor 3, which is rotatably supported; and a conventional drum (not shown), which is supported to move back and forth synchronously with the rotational movement of the rotor 3. The rotor 3 has a pair of arms 3a that rotate around the drum. A guide ring support member 3b, on the front end of each arm 3a, is rotatably supported between a line winding position and a line release position. At this time, the base end of one of the guide rings 5 is mounted on a line guide portion (line roller) 6 integrally provided on the guide ring support member 3b.
[0023] Within the reel body 2, a handle shaft is rotatably supported by bearings, and a handle (not shown) is mounted on its protruding end. A drive force transmission mechanism 10 is provided on the handle shaft, which transmits its driving force to the rotor 3 to rotate it when the handle is rotated. Furthermore, the drive force transmission mechanism 10 includes: a drive gear rotatably mounted integrally on the handle shaft; and a pinion 11 having pinion teeth that mesh with the drive gear. The pinion 11 extends in a front-rear direction orthogonal to the handle shaft and functions as a rotation drive shaft, the latter having an axially extending cavity 11a formed inside. A spool shaft (not shown) passes through the cavity 11a, engaging with a swing mechanism (not shown) that moves the spool back and forth when the handle (not shown) is rotated, and a spool is mounted on the top end of the spool shaft.
[0024] A pinion 11 is rotatably supported on the reel body 2. The pinion 11 extends toward the spool side, and a rotor 3 is integrally rotatably mounted on its top end. A through-hole of a boss 3A formed in the center portion of the rotor 3 is fitted into the top end of the pinion 11 and secured by a fastening nut (not shown). Furthermore, a one-way clutch 20 constituting a reverse-prevention mechanism is disposed on the pinion 11. With this configuration, when the handle is reeled in, the rotor 3 is rotated via the drive force transmission mechanism 10, and the spool moves back and forth in the front-to-back direction via the swing mechanism (not shown) and the spool shaft (not shown). Thus, the fishing line is evenly wound onto the spool through the fishing line guide 6 of the rotating rotor 3.
[0025] Next, refer to Figure 1 and Figure 2 as well as Figures 3 to 10 The one-way clutch 20 on a fishing reel 1 according to one embodiment of the present invention will be described.

Figure 9 (b) is a diagram illustrating the projected length of the one-way clutch 20 of the fishing reel 1 according to an embodiment of the present invention in the clutch engaged state (locked state), as described later. Figure 10 This is a diagram illustrating the relationship between the force-applying spring 24 and the boss 31 on the one-way clutch 20 of the fishing reel 1 according to one embodiment of the present invention.
[0026] like Figures 3 to 5As shown, a fishing reel 1 is fitted with a one-way clutch 20. This one-way clutch 20 allows rotation of a rotary drive shaft supported within the reel body 2 in one direction and prevents rotation in the other direction. The one-way clutch 20 has a retainer 23 (assembly structure) that connects a first retainer 23A and a second retainer 23B by overlapping vertically. The first retainer 23A includes an inner ring 21, an outer ring 27, multiple rolling elements 25, multiple force-applying springs 24 that apply force to each of the multiple rolling elements 25, and multiple retaining portions 23a that retain each of the multiple force-applying springs 24. The second retainer 23B is mounted on the first retainer 23A in such a way that it clamps the outer ring 27 axially. The first retainer 23A and the second retainer 23B are connected such that they can rotate circumferentially within a specified angle range (e.g., within a specified angle range). Figure 4 The retainer 23 rotates relative to the second retainer 23B in the direction indicated by the arrow. As described above, the retainer 23 is modularized (a modular structure that integrates multiple components; also called an ASSY), thereby enabling integrated operation. Furthermore, by constructing the retainer 23 with multiple components (first retainer 23A and second retainer 23B), the axial disengagement of components such as the outer ring can be suppressed, making modularization easy. The one-way clutch 20 is configured such that, by operating an operating lever (not shown) provided on the fishing reel 1, the first retainer 23A rotates relative to the second retainer 23B through the rotational action of the operating part 29 provided on the first retainer 23A that is linked to the action of the operating lever, thereby enabling the one-way clutch 20 to be engaged or disengaged. That is, the first retainer 23A is provided with an operating part 29 for performing a relative rotational action with the second retainer 23B.
[0027] According to the fishing reel 1 of the present invention, a fishing reel is provided that can switch between reversing and non-reversing the one-way clutch, and can suppress the size (height) of the one-way clutch. When the operating part is rotated at a predetermined angle in the circumferential direction, the holding part 23a presses the spring, and the rolling member 25 abuts against the wedge (sloping wedge) shaped surface described later, thereby disabling the reversal of the one-way clutch. On the other hand, when the operating part is rotated in the opposite direction in the circumferential direction at a predetermined angle, the rolling member 25 moves to the free area described later, thereby making the rolling member 25 and the inner ring 21 non-contact, and as a result, enabling the reversal of the one-way clutch.
[0028] The inner ring 21 is prevented from rotating relative to the pinion 11 and functions as a drive shaft that rotates integrally with the pinion 11. Specifically, the cross-section of the pinion 11 has a partially non-circular portion, and by engaging the non-circular portion of the inner ring 21 with this portion, the inner ring 21 can rotate integrally with the pinion 11. The retainer 23 is disposed radially outward of the inner ring 21, and as described above, it is constructed by overlapping and integrating the first retainer 23A and the second retainer 23B in the vertical direction. In this embodiment, they are arranged with the first retainer 23A on the lower side and the second retainer 23B on the upper side, and these first retainers 23A and second retainers 23B are integrally connected and installed in a manner that clamps the outer ring 27.
[0029] Furthermore, while there are no particular limitations on the connection structure (engaging fixing part) of the integrated first retainer 23A and second retainer 23B, the one-way clutch 20 in the fishing reel 1 according to one embodiment of the present invention has the following configuration: On the first retainer 23A, a displaceable locking part protruding axially is formed at predetermined intervals in the circumferential direction; simultaneously, a locked part that is embedded in the locking part is formed at a corresponding position on the second retainer 23B. In this configuration, by moving the second retainer 23B axially in a manner that clamps the outer ring 27 and engaging the locking part with the locked part, the first retainer 23A and second retainer 23B can be integrated. Details will be described later.
[0030] The first retainer 23A has a plurality of retaining portions 23a arranged at certain intervals in the circumferential direction. Each retaining portion 23a has an opening in the circumferential direction (e.g., Figure 5 As shown, in the recesses (opening in the counterclockwise rotation direction), the force spring 24 is supported by the base 23b and held within each recess. Furthermore, rolling members 25 are arranged between each holding portion, and each rolling member 25 is circumferentially (e.g., by the force spring 24) Figure 4 Apply force in the counterclockwise direction of rotation (or in the opposite direction).
[0031] The outer ring 27 is disposed radially outward of each rolling element 25 and is formed as an annular ring (or approximately an annular ring). Furthermore, as... Figure 4 , Figure 5 As shown, on the inner circumferential surface of the outer ring 27, wedge regions 27a that prevent the rotation of each rolling member 25 and free regions 27b that allow the rolling members 25 to rotate freely are continuously formed (multiple of these two regions are alternately formed on the inner circumferential surface of the outer ring 27). When each rolling member 25 held in the retainer 23 (first retainer 23A) is in a state where the force-applying spring 24 applies force to the wedge region side, it becomes a locked state. Furthermore, the outer circumferential surface 27d of the outer ring 27 is formed as a circle (including a roughly circular shape).
[0032] A protrusion 27c is provided on a portion of an outer ring 27 that is generally annular, projecting radially outward. This protrusion functions to restrict the rotation of the outer ring 27. The protrusion 27c is integrally formed, projecting radially outward from the outer peripheral surface 27d of the outer ring 27, and there are one or more such protrusions. In this case, since a large torque is applied to the outer ring, there is a possibility of stress concentration and bias towards one point; therefore, it is preferable to form two or more at equal intervals.
[0033] The first retainer 23A has the same shape as the outer ring 27, and preferably has a protrusion of approximately the same shape integrally formed at the same position (the position where they overlap in the axial direction) as the protrusion 27c of the outer ring 27. Similar to the outer ring, this protrusion is also provided in two places at 180° intervals and opposite each other in a manner that clamps the axis (center О), and has a rotation limiting function.
[0034] In addition, such as Figure 7 and Figure 8 As shown, in order to switch between the clutch disengagement state (free state) and the clutch engagement state (locked state) of the one-way clutch 20, the first retainer 23A is configured to be circumferentially (e.g., relative to the second retainer 23B) capable of switching between the clutch disengagement state (free state) and the clutch engagement state (locked state) of the one-way clutch 20. Figure 4 The first retainer 23A is more preferably configured to rotate relative to the second retainer 23B in the circumferential direction (e.g., in the direction indicated by the arrow) within a range of 0 to 20 degrees. Furthermore, the first retainer 23A is preferably configured to rotate relative to the second retainer 23B in the circumferential direction (e.g., in the direction indicated by the arrow). Figure 4 The relative rotation is within the range of 0 to 16 degrees in the direction indicated by the arrow. The reason for adopting the above angle range is based on the physical working range of each component. In addition, it is to achieve the following configuration: in the locked state, the rolling member 25 and the retaining part 23a will not interfere with each other, and the clutch engagement state (locked state) of the one-way clutch 20 can be reliably realized. In the free state, the rolling member 25 can disengage from the inner ring 21. Here, defining an angle as 0 degrees means that the operating part 29 is directed to one side (e.g., Figure 7 When the clutch reaches its destination in the right direction (or when the clutch ring 11 contacts the rolling element 25 if the clutch is engaged (locked), the relative angle between the first retainer 23A and the second retainer 23B is as follows: (e.g., when the clutch ring 11 contacts the rolling element 25) Furthermore, the specified angle of 20 degrees refers to the angle between the operating part 29 and the other side (e.g., in the right direction). Figure 7 The relative angle between the first retainer 23A and the second retainer 23B when the vehicle reaches the end point (in the left-middle direction) (or when the rolling element 25 has completely disengaged from the clutch ring 11 if the clutch is disengaged (free state)).
[0035] In addition, such as Figure 6 (and Figure 5 )as well as Figure 7 , 8 As shown, the second retainer 23B is configured to have a plurality of protrusions 31 on its inner (back) surface 23Ba. Furthermore, as... Figure 10 As shown, each of the plurality of bosses 31 is positioned 0.05 mm to 0.2 mm above each of the plurality of force-applying springs 24. With this configuration, during normal use, contact between the bosses 31 and the force-applying springs 24 can be avoided. At the same time, the bosses 31 can effectively prevent the force-applying springs 24 held on the retaining portion 23a from dislodging from the retaining portion 23a and moving upward.
[0036] Furthermore, each of the plurality of bosses 31 of the second retainer 23B is configured such that, when the first retainer 23A rotates relative to it, each of the plurality of force-applying springs 24 is circumferentially (e.g., ...). Figure 4 The first retainer 23A can move relative to the second retainer 23B because the boss 31 will not collide with the force-adding spring 24 and can move relative to it.
[0037] In addition, such as Figure 5 As shown, in order to enable the rotational movement of the boss 31 of the second retainer 23B, each of the plurality of retaining portions 23a of the first retainer 23A is circumferentially (e.g., Figure 5 The first retainer 23A has a cutout 23e in the circumferential direction. According to this configuration, since the retaining part 23a is cut out in the circumferential direction while holding the force-adding spring 24 by means of the retaining part 23a, the boss 31 of the second retainer 23B can move up and down in the circumferential direction without colliding with the retaining part 23a, thereby enabling the first retainer 23A to rotate relative to the second retainer 23B within the aforementioned predetermined angle range.
[0038] More specifically, each of the plurality of retaining portions 23a of the first retainer 23A has a base 23b, on which are provided: a support wall 23d for supporting each of the plurality of force-adding springs 24; and the aforementioned cutout 23e for allowing the boss 31 of the second retainer 23B to rotate.
[0039] In addition, such as Figure 4 and Figure 5 As shown, the first retainer 23A has a locking portion 32, and the second retainer 23B has a locked portion 33 that locks with the locking portion 32. The locking portion 32 is configured to be circumferentially (e.g., relative to the locked portion 33) Figure 4 The first retainer 23A and the second retainer 23B can be connected such that the first retainer 23A can rotate relative to the second retainer 23B in the circumferential direction.
[0040] In addition, such as Figure 4 As shown, the locking portion 32 has a claw-shaped portion 32a, and the locked portion 33 has an opening portion 33a and an edge portion 33b. The claw-shaped portion 32a is locked to the edge portion 33b, and the claw-shaped portion 32a is configured to be able to move circumferentially (e.g., along the edge portion 33b). Figure 4 The first retainer 23A can rotate relative to the second retainer 23B in the circumferential direction (as indicated by the arrow). According to this configuration, the first retainer 23A can rotate relative to the second retainer 23B in the circumferential direction, and the first retainer 23A can be connected to the second retainer 23B.
[0041] In addition, such as Figure 4 As shown, in its locked state, the one-way clutch 20 has multiple rolling members 25 each in contact with a wedge-shaped surface 23f formed on the inner surface of the first retainer 23A, thereby preventing the rotation of the multiple rolling members 25. Here, the locked state means that by rotating the operating part 29 by a predetermined angle in the circumferential direction, the retaining part 23a presses the spring, the rolling members 25 abut against the wedge-shaped surface 23f, and the reversal of the one-way clutch is not possible (this is true throughout this specification).
[0042] In addition, such as Figure 9 (a) Figure 9 As shown in (b), in its locked state, the length of each of the plurality of bosses 31 is 45% to 55% of the axial (longitudinal) length S of each of the plurality of force springs 24, as projected from above (viewed from the upper side in the axial direction X of the one-way clutch 20) (projected length of each of the plurality of force springs 24 in the axial (longitudinal direction) (the axial length of the overlapping projections)). According to this configuration, not only can the bosses 31 be prevented from colliding with the rolling member 25, but the bosses 31 can also be used to effectively prevent the force springs 24 held on the retaining part 23a from disengaging from the retaining part 23a and disengaging upward.
[0043] The plurality of bosses 31 of the second retainer 23B are each configured to overlap at least a portion of each of the plurality of rolling members 25 when viewed axially from the one-way clutch 20. According to this configuration, the bosses 31 can be arranged in the space between the rolling members 25, the force spring 24, and the retaining portion 23a, effectively preventing the force spring 24, which is held in the retaining portion 23a, from disengaging from the retaining portion 23a and disengaging upwards, and reducing the axial dimension (height) of the one-way clutch 20.
[0044] The dimensions, raw materials, and configurations of the constituent elements described in this specification are not limited to those explicitly stated in the embodiments. These constituent elements can be modified within the scope of this invention to have arbitrary dimensions, raw materials, and configurations. Furthermore, constituent elements not explicitly stated in this specification may be added to the described embodiments, and some constituent elements described in each embodiment may be omitted.
