Abstract
Description
[Technical Field]
[0001] The present invention relates to a fishing reel. [Background technology]
[0002] Conventionally, fishing reels have been provided with a reel body, a handle rotatably attached to the reel body, a drive shaft that rotates integrally with the handle, a spool rotatably supported on the reel body, a drive gear that rotates integrally with the spool, a drag mechanism that regulates the relative rotation between the drive shaft and the drive gear, and a spool shaft that rotates integrally with the spool; in this way, the drag mechanism is provided on the drive gear shaft assembly (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 6649699 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in fishing reels with this type of drag mechanism (commonly referred to as a "star drag mechanism"), the output from the spool is reduced to a value divided by the gear ratio, resulting in a problem where the maximum drag force is lower than that of spinning reels or lever drag reels. To solve these problems, for example, if the number of drag groups on the drive gear shaft is increased to strengthen the drag force, the handle will be moved away from the reel body by the same amount, which will cause the reel to wobble when winding with the handle, making it difficult to apply force.Furthermore, if the drag force is strengthened, the resistance strength of the roller clutch will also need to be strengthened, which will require a larger roller clutch, which will increase the size of the reel, and there is room for improvement in this regard.
[0005] The present invention was made in consideration of these circumstances, and its purpose is to provide a fishing reel that can add drag force as needed while preventing the reel from becoming too large. [Means for solving the problem]
[0006] (1) A first aspect of the fishing reel of the present invention is characterized by comprising a reel body, a handle rotatably mounted on the reel body, a drive shaft that rotates integrally with the handle, a spool rotatably supported on the reel body, a drive gear that rotates integrally with the spool, a first drag mechanism that regulates the relative rotation between the drive shaft and the drive gear, a spool shaft that rotates integrally with the spool, a second drag mechanism that regulates the relative rotation between the spool shaft and the reel body, and a regulation switching mechanism that switches the second drag mechanism between a regulated state and an unregulated state.
[0007] According to the first aspect of the fishing reel of the present invention, when the drag force (braking force) on the spool shaft by the first drag mechanism is insufficient, the restriction switching mechanism can be switched to a restriction state in which the second drag mechanism restricts the relative rotation between the spool shaft and the reel body, thereby adding drag force by the second drag mechanism to the drag force by the first drag mechanism.
[0008] (2) In a second aspect of the present invention, in the fishing reel of the first aspect, the second drag mechanism has a first drag plate that rotates integrally with the spool shaft, a second drag plate that is arranged opposite the first drag plate around the spool shaft, and a regulating portion that regulates the relative rotation between the first drag plate and the second drag plate, and the regulation switching mechanism preferably switches the rotation of the second drag plate around the spool between rotatable and non-rotatable.
[0009] In this case, the restriction switching mechanism switches between the restricted state and the non-restricted state by switching the rotation of the second drag plate between rotatable and non-rotatable, so that drag force can be added as needed with a relatively simple configuration.
[0010] (3) Aspect 3 of the present invention is a fishing reel according to aspect 2, wherein the second drag plate has an engagement recess, and the restriction switching mechanism has a restriction switching operation unit and an engagement claw unit that can engage with the engagement recess, and the restriction switching operation unit is used to engage and disengage the engagement recess and the engagement claw unit, thereby switching the second drag plate between rotatable and non-rotatable around the spool.
[0011] In this case, by engaging and disengaging the engagement recess of the second drag plate with the engagement claw portion of the restriction switching operation portion, the rotation of the second drag plate around the spool can be easily switched between rotatable and non-rotatable.
[0012] (4) In a fourth aspect of the present invention, in the fishing reel of the third aspect, it is preferable that the engagement recess of the second drag plate has a gear shape that prevents a first rotation in the fishing line releasing direction and allows a second rotation in the fishing line rewinding direction.
[0013] In this case, when the second drag plate makes a second rotation in the fishing line winding direction, the gear-shaped engaging recess allows the second rotation, so that the second drag plate can be rotated.
[0014] (5) A fifth aspect of the present invention may be characterized in that the fishing reel of any one of the first to fourth aspects further includes an adjustment mechanism that adjusts the restricting force of the second drag mechanism.
[0015] In this case, the restricting force of the second drag mechanism can be adjusted by the adjustment mechanism.
[0016] (6) In a sixth aspect of the present invention, in the fishing reel of the fifth aspect, it is preferable that the adjustment mechanism has an adjustment switching operation part that switches between an adjustable state and an unadjustable state.
[0017] In this case, by operating the adjustment switching operation portion, the adjustment mechanism can be easily switched between the adjustable state and the non-adjustable state, thereby adjusting the restricting force.
[0018] (7) A seventh aspect of the present invention is a fishing reel according to the fifth aspect, wherein the second drag mechanism has a first drag plate that rotates integrally with the spool shaft, a second drag plate that is provided opposite the first drag plate, and a regulating portion that applies a regulating force to the relative rotation between the first drag plate and the second drag plate, and the adjustment mechanism preferably has an adjustment portion that adjusts the regulating force exerted by the regulating portion.
[0019] In this case, the restricting force of the restricting portion is adjusted by the adjusting portion, whereby the restricting force of the second drag mechanism can be adjusted.
[0020] (8) Aspect 8 of the present invention may be characterized in that, in the fishing reel of aspect 7, the second drag mechanism is provided on the reel body and includes a switching device that connects or disconnects the rotation of an outer gear of the second drag plate, the rotation of which is restricted, and a gear that rotates integrally with the spool shaft.
[0021] In this case, a switching device provided on the reel body can couple or cut off the rotation of the outer peripheral gear of the second drag plate, whose rotation is restricted, and the gear that rotates integrally with the spool shaft.
[0022] (9) In a ninth aspect of the present invention, in the fishing reel of the seventh aspect, it is preferable that the adjustment part comprises an adjustment knob provided on the reel body, and an adjustment gear provided around the axis of the spool, which moves back and forth in the axial direction of the spool axis by the adjustment knob, thereby adjusting the regulating force of the regulating part.
[0023] In this case, by operating the adjustment knob, the regulation force of the regulating part that regulates the relative rotation between the first drag plate and the second drag plate can be adjusted by the adjustment gear that moves back and forth in the axial direction of the spool shaft. [Effects of the Invention]
[0024] According to the fishing reel of the present invention, it is possible to suppress an increase in the size of the reel while increasing the maximum drag force as needed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0026] Hereinafter, an embodiment of a fishing reel according to the present invention will be described with reference to the drawings. Note that in each drawing, the scale of each component may be changed as necessary to make each component large enough to be visible. In this embodiment, a dual-bearing fishing reel will be described as an example.
[0027] (Overall composition) As shown in FIGS. 1 and 2, the fishing reel of this embodiment is employed as a dual-bearing reel 1 capable of winding up a fishing line. The dual-bearing reel 1 comprises a reel body 10, a spool shaft 20 rotatably mounted in the center of the reel body 10, a spool 2 supported non-rotatably on the spool shaft 20, a handle 3 arranged on the side of the reel body 10, and a drag adjustment unit 4 for drag adjustment arranged on the reel body 10 side of the handle 3.
[0028] As shown in FIG. 2, the reel body 10 of the dual-bearing reel 1 is equipped with drag mechanisms 40, 50 that transmit the rotation of the handle 3 to the spool 2 in the fishing line reeling direction via the drive gear 34 and pinion gear 35, and also apply a drag force to the rotation of the spool 2 in the fishing line reeling direction.
[0029] (reel body) The reel body 10 comprises a pair of metal right and left plate frames 10A and 10B, a plurality of connecting frames 11 that connect the right and left plate frames 10A and 10B at the front, rear, and bottom, and cover members 12A and 12B that cover the outside of the right and left plate frames 10A and 10B, respectively. A rod attachment portion 13 for attaching the dual-bearing reel 1 to a fishing rod is integrally formed on the lower connecting frame 11. The right side plate frame 10A, the left side plate frame 10B and connecting frame 11 are integrally formed by cutting metal.
[0030] As shown in Figure 1, the right cover member 12A covers the outside of the right side plate frame 10A. The right side plate frame 10A and the left side plate frame 10B have openings through which the spool 2 can pass. The left cover member 12B (see Figure 4) rotatably supports the left end of the spool shaft 20.
[0031] As shown in Fig. 2, a rotation transmission mechanism 30A for transmitting the rotation of the handle 3 to the spool 2 is disposed in a first housing space S1 inside the right side plate frame 10A. Furthermore, a clutch control mechanism (not shown) for controlling the clutch mechanism in response to the operation of the clutch operating unit 14 shown in Fig. 1, and a first drag mechanism 40 (described later) are disposed in the first housing space S1. Furthermore, a second drag mechanism 50 (described later) is disposed in a second housing space S2 inside the left side plate frame 10B.
[0032] (spool shaft) 2, the spool shaft 20 is rotatably supported by the right cover member 12A and the left cover member 12B. The spool shaft 20 is rotatably supported by two bearings, a first bearing 21A and a second bearing 21B, which are arranged on the outer circumferential surface of the spool shaft 20. The spool shaft 20 is fixed integrally with the spool 2.
[0033] (spool) As shown in FIGS. 2 and 3, the spool 2 has a bobbin trunk 22 and a pair of flanges 23 integrally formed on both ends of the bobbin trunk 22.
[0034] (handle) As shown in Figures 1 and 2, the drive shaft 30, which serves as the rotation axis of the handle 3, is disposed in front of and parallel to the spool shaft 20. The handle 3 is fixed to the protruding end of the drive shaft 30, which rotates integrally with the handle 3. The drive shaft 30 is rotatably supported by the reel body 10. The handle 3 has a handle arm 31 extending in a direction intersecting the drive shaft 30, and a handle grip 32 rotatably attached to the tip of the handle arm 31. The handle arm 31 is a metal plate-shaped member, and the drive shaft 30 is attached to a non-circular through-hole formed at the base end of the arm so as to be rotatable integrally with the handle 3.
[0035] (Rotation transmission mechanism) The rotation transmission mechanism 30A includes a mechanism that transmits a first rotation of the handle 3 in the fishing line winding direction to the spool 2, and a clutch mechanism that switches on and off the transmission of the first rotation in the fishing line winding direction from the spool 2 to the handle 3 side. The rotation transmission mechanism 30A comprises a pinion gear shaft 33 which is detachably connected to the spool shaft 20, a drive shaft 30 to which the handle 3 is fixed, a drive gear 34 connected to the drive shaft 30, and a pinion gear 35 which is provided on the pinion gear shaft 33 and meshes with the drive gear 34.
[0036] The pinion gear shaft 33 is engaged with the spool shaft 20 of the spool 2 in an externally fitted state. The spool shaft 20 is inserted into a through hole 33a of the pinion gear shaft 33. The pinion gear shaft 33 can be moved axially back and forth relative to the spool shaft 20 by switching on and off the clutch mechanism, and can be engaged and disengaged with the spool shaft 20 by moving it back and forth. In the engaged state, the pinion gear shaft 33 rotates integrally with the spool shaft 20. In other words, the rotation of the handle 3 is transmitted by the rotation transmission mechanism 30A, causing the spool 2 to rotate in the fishing line reeling direction.
[0037] The drive shaft 30 is disposed inside the right side plate frame 10A. The drive shaft 30 extends in the left-right direction and passes through the right cover member 12A in the axial direction, with the drag adjustment unit 4 and the handle 3 disposed at the end of the shaft. The drive shaft 30 corresponds to the handle shaft and is disposed in the left-right direction, i.e., parallel to the axial direction of the spool 2.
[0038] The drive shaft 30 is connected to the handle 3 and rotatably supported relative to the right side frame plate 10A. A drive gear 34 is provided on the drive shaft 30. Furthermore, a plurality of drag washers or plate washers made of thin metal plates that constitute a first drag mechanism 40 are provided on the drive gear 34 and are stacked in the axial direction on the drive shaft 30.
[0039] The drive gear 34 is connected to the left side X2 of the drive shaft 30 via the pinion gear 35 so that it rotates integrally with the drive shaft 30 when the fishing line is pulled in the reeling direction with less than the drag force, and the drive shaft 30 rotates relative to the drive gear 34 via the pinion gear 35 when the fishing line is pulled in the reeling direction with more than the drag force. The drive gear 34 has a gear on its outer periphery that meshes with the pinion gear 35. The pinion gear 35 has an outer circumferential gear that meshes with the drive gear 34 .
[0040] With the dual-bearing reel 1 configured in this manner, when the clutch is engaged and the reel is being manually wound, the rotational power from the handle 3 is transmitted to the spool 2 in the first rotation in the fishing line winding direction in the following order: handle 3, drive shaft 30, first drag mechanism 40 (and second drag mechanism 50), drive gear 34, pinion gear 35, pinion gear shaft 33, and spool 2. At this time, the dual-bearing reel 1 transmits rotational power from the handle 3 to the spool 2 by frictional forces of the drag washers and other components of the drag mechanism 40, thereby demonstrating drag performance.
[0041] The drag mechanism includes a first drag mechanism 40 that restricts the relative rotation between the drive shaft 30 and the drive gear, a second drag mechanism 50 that restricts the relative rotation between the spool shaft 20 and the reel body 10, and a restriction switching mechanism 60 that switches the second drag mechanism 50 between a restricted state and a non-restricted state.
[0042] (1st drag mechanism) 2, the first drag mechanism 40 includes a stopper gear 42, a first drag washer 43, and a drive gear 34, which are arranged in this order from the base end 30b on the left side X2 of the drive shaft 30 to the tip end 30a on the right side X1 of the drive shaft 30, stacked in the axial direction X. Furthermore, a plurality of second drag washers 44 and a plurality of plate washers 45 are arranged on the right side X1 of the drive gear 34, stacked in the axial direction X. The stopper gear 42 and the plate washers 45 are attached to the drive shaft 30 so as to be non-rotatable.
[0043] In the first drag mechanism 40, the frictional force of the sliding surfaces on both sides of each drag washer 43, 44 transmits rotational power from the handle 3 to the spool 2, thereby exerting drag performance. In the dual-bearing reel 1, with the clutch engaged, rotational power from the handle 3 is transmitted to the spool 2 in the following order: handle 3, drive shaft 30, drag washers 43, 44, drive gear 34, pinion gear 35, pinion gear shaft 33, spool shaft 20, and spool 2. If the fishing line is pulled strongly in the reeling direction, a force greater than the drag force is applied to the drive gear 34, i.e., the force acts in the order of the spool 2, pinion gear 35, and drive gear 34. At this time, slippage occurs between the drive gear 34, drag washers 43 and 44, stopper gear 42, and plate washer 45, causing the fishing line to reel out.
[0044] (Second drag mechanism) As shown in FIG. 2, the second drag mechanism 50 supplements and adds a supplementary drag force to the drag force generated by the first drag mechanism 40. The second drag mechanism 50 includes a main drag plate 51 (first drag plate), a drag receiver gear 52 (second drag plate) provided opposite the main drag plate 51 around the spool shaft 20, and a drag nut 53 (restriction portion) that restricts the relative rotation between the main drag plate 51 and the drag receiver gear 52. The main drag plate 51, the drag receiver gear 52, and the drag nut 53 are arranged coaxially with the spool shaft 20.
[0045] As shown in FIG. 3 , the main drag plate 51 is a disc-shaped brake disc made of metal such as stainless steel, and is disposed between the drag receiver gear 52 and the drag nut 53. Specifically, a washer 54A made of carbon reinforced fiber or the like is interposed between the main drag plate 51 and the drag receiver gear 52, and a metal disc spring 54B is interposed between the main drag plate 51 and the drag nut 53. The main drag plate 51 is fixed to the spool shaft 20 so as not to rotate and rotates integrally with the spool shaft 20. The main drag plate 51 generates and adjusts a drag force in the axial direction X of the spool shaft 20 between the drag receiver gear 52 and the main drag plate 51 by adjusting the fastening of the drag nut 53 by advancing and retracting the drag plate 51 in the axial direction X relative to the spool shaft 20.
[0046] The drag receiver gear 52 is a stainless steel, disc-shaped brake disc. The left side (X2) of the drag receiver gear 52 has a receiving recess 52b recessed axially inward (right side (X1)) in the center of a plan view as seen from the axial direction (X) of the spool shaft 20. The main drag plate 51 is disposed coaxially with the drag receiver gear 52 in the receiving recess 52b. The bottom surface of the receiving recess 52b (corresponding to the plate surface of the drag receiver gear 52) and the main drag plate 51 are in contact via a first carbon washer 54A. The right side of the drag receiver gear 52 is in contact via a second carbon washer 54C.
[0047] As shown in FIGS. 3 and 5, the drag receiver gear 52 has a plurality of engagement recesses 52a in the circumferential direction on its outer periphery. The engagement recesses 52a have engagement surfaces 52c that face a first direction E1, which is one of the rotation directions, and a second direction E2, which is the opposite direction. The engagement recesses 52a are engaged with engagement claws 62 of a restriction switching mechanism 60 that restricts the rotation of the drag receiver gear 52 in the first direction E1 (first rotation). That is, when the drag receiver gear 52 rotates in the first direction E1 (first rotation), the engagement claws 62 engage with the engagement recesses 52a, causing the engagement claws 62 to abut against the engagement surfaces 52c, restricting and stopping the rotation of the drag receiver gear 52 in the first direction E1 (first rotation). On the other hand, when the drag receiver gear 52 rotates in the second direction E2 (second rotation), the engagement recesses 52a rotate over the engagement claws 62, allowing the drag receiver gear 52 to rotate in the second direction E2. That is, the engaging recess 52a of the drag receiving gear 52 has a gear shape that allows the second rotation in the fishing line winding direction.
[0048] The drag nut 53 is attached to the left side X2 of the main drag plate 51 by a screw to be rotatable and movable relative to the spool shaft 20. The drag nut 53 is threadedly coupled to the spool shaft 20, and moves to the right side X1 in the axial direction X by tightening the threaded coupling by rotating the threaded coupling. As the drag nut 53 moves to the right side X1, it presses the main drag plate 51 from the left side X2, restricting relative rotation and generating a frictional force between the main drag plate 51 and the drag receiver gear 52. The frictional force is adjusted by moving the drag nut 53 back and forth in the axial direction X, thereby adjusting the drag force.
[0049] (Regulation Switching Mechanism) 5, the restriction switching mechanism 60 has a restriction switching operation unit 61 and an engagement claw unit 62 that can engage with the engagement recess 52a of the drag receiving gear 52. The restriction switching mechanism 60 engages or disengages the engagement recess 52a and the engagement claw unit 62 using the restriction switching operation unit 61, thereby switching the rotation of the drag receiving gear 52 around the spool 2 between rotatable and non-rotatable.
[0050] The restriction switching operation unit 61 is connected to the engagement claw 62 and is operated to selectively move the engagement claw 62 between an engaged and disengaged position with respect to the engagement recess 52a. The restriction switching operation unit 61 includes an operation unit main body 611, a connecting piece 612 extending from the operation unit main body 611, and a support shaft 613 that rotatably supports one end of the connecting piece 612 and the end 62a of the engagement claw 62.
[0051] 5, when the restriction switching operation unit 61 is operated to move from the disengagement position P1 (indicated by the two-dot chain line in FIG. 5) to the engagement position P2 (indicated by the solid line in FIG. 5), one end of the connecting piece 612 at the end 62a of the engagement claw 62 swings around the support shaft 613. As a result, the locking claw 622 at the tip 621a of the end 62a of the engagement claw 62 engages with the engagement recess 52a of the drag receiver gear 52, restricting rotation of the drag receiver gear 52 in the first direction E1, i.e., rotation in the fishing line reeling direction. As described above, the drag receiving gear 52 generates a frictional force between the drag nut 53 and the adjusted carbon washer by moving the drag nut 53 back and forth in the axial direction X relative to the spool shaft 20.
[0052] In this way, by operating the restriction switching mechanism 60, which switches the second drag mechanism 50 between a restricted state and an unrestricted state, the second drag mechanism 50 enters a state in which it adds and supplements the drag force generated by the first drag mechanism 40.
[0053] The operating unit main body 611 is fixed to the other end of the connecting piece 612 and is provided so as to protrude outward from an opening 12b formed in the left cover member 12B and be operable. As shown in Figure 2, the operating unit main body 611 is located in front of the left cover member 12B of the reel body 10, that is, on the left side X2 (opposite the handle 3) of the axial center of the spool. By providing the operating unit main body 611 in this position, a thumbing space can be provided on the handle 3 side (right side X1) from the axial center of the spool, making thumbing easier and improving usability.
[0054] In this way, when the drag force applied by the first drag mechanism 40 to the spool shaft 20 is insufficient, the restriction switching mechanism 60 can switch to a restriction state in which the second drag mechanism 50 restricts the relative rotation between the spool shaft 20 and the reel body 10, thereby adding the drag force applied by the second drag mechanism 50 to the drag force applied by the first drag mechanism 40. That is, in this embodiment, the maximum drag force can be added as needed by combining the drag forces of the first drag mechanism 40 and the second drag mechanism 50. Furthermore, the drag force applied by the second drag mechanism 50 can be prevented from damaging conventional stoppers and gears.
[0055] The drag force added by the second drag mechanism 50 is adjusted by the relative position of the drag nut 53 and the spool shaft 20 due to the threaded engagement between them. Therefore, it is possible to remove the spool 2 together with the second drag mechanism 50 from the reel body 10, adjust the drag nut 53, and then reassemble them into the reel body 10. However, in this embodiment, an adjustment mechanism 70 is provided that can adjust the drag force added by the second drag mechanism 50 without removing the spool 2 together with the second drag mechanism 50 from the reel body 10.
[0056] In the adjustment mechanism 70 shown in FIG. 6, when the operating unit 614 (see FIG. 4) of the restriction switching mechanism 60 is operated to switch to the restriction position T1 (two-dot chain line shown in FIG. 4), the link mechanism 77 causes the locking pawl 71 to swing about the shaft 72 and engage with a gear portion 53a having multiple teeth in the circumferential direction on the outer circumferential surface of the drag nut 53. At this time, the position of the operating unit 614 is the restriction position, and the drag nut 53 is unable to rotate relative to the reel body 10 (left cover member 12B) due to engagement with the locking pawl 71. Note that the solid line of the operating unit 614 in FIG. 4 indicates the restriction release position T2.
[0057] When the drag nut 53 is unable to rotate relative to the left cover member 12B, rotating the spool 2 together with the spool shaft 20 generates relative rotation between the drag nut 53 and the spool shaft 20 due to the threaded engagement between them. This allows the drag nut 53 to move in the axial direction X relative to the spool shaft 20, adjusting the frictional force with the drag receiver 52. For example, when the operating unit 614 shown in FIG. 4 is switched to the restricting position T1 and the spool 2 is rotated in the fishing line-releasing direction, the drag nut 53 moves to the right side X1 in the axial direction X relative to the spool shaft 20, increasing the drag force added by the second drag mechanism 50. When the spool 2 is rotated in the fishing line-reeling direction, the drag nut 53 moves to the left side X2 in the axial direction X, adjusting the drag force added by the second drag mechanism 50 to decrease.
[0058] The dual-bearing reel 1 according to the first embodiment configured as described above can suppress an increase in the size of the reel while increasing the maximum drag force as needed.
[0059] (Second embodiment) The second drag mechanism 50A of the dual-bearing reel 1A (fishing reel) according to the second embodiment shown in FIGS. 7 to 10 includes a second braking force adjuster 80A (adjuster). Figure 7 is a cross-sectional view of a dual-bearing reel 1A according to a second embodiment. Figure 8 is a side view of the dual-bearing reel 1A shown in Figure 7, viewed from the axial left. Figure 9 is a perspective view showing the configuration of a second drag mechanism 50A of the dual-bearing reel 1A shown in Figure 7. Figure 10 is a cross-sectional view showing the main parts of the adjustment mechanism for the second drag mechanism 50A.
[0060] The dual-bearing reel 1 of the first embodiment described above is configured so that the drag nut 53 cannot rotate with respect to the reel body 10 (left cover member 12B) and the drag nut 53 moves toward and away from the spool shaft 20 by rotating the spool shaft 20 relative to it, thereby adjusting the drag force to be added or added. In contrast, as shown in Figure 7, the dual-bearing reel 1A of the second embodiment is configured differently from the dual-bearing reel 1 of the first embodiment described above mainly in that the rotation of the spool shaft 20 is restricted and the drag nut 53 is rotated relative to it, thereby moving the drag nut 53 toward and away from the spool shaft 20, and in that an adjustment knob 89 (see Figure 8) is provided on the left cover member 12B to enable adjustment. The basic configuration of the second drag mechanism 50A is the same as that of the first embodiment, and therefore a description thereof will be omitted here.
[0061] The dual-bearing reel 1A of the second embodiment will now be described in detail. As shown in Figures 9 and 10, the second braking force adjuster 80A includes an adjustment shaft 87 that is movable in the axial direction X, an adjustment gear 81 that is provided on the adjustment shaft 87 and rotates integrally with it, an adjustment knob 89 that rotates the adjustment gear, and a lock gear 55 that rotates integrally with the spool shaft 20.
[0062] The adjustment shaft 87 extends in the axial direction X in parallel with the spool shaft 20. A left end 87b of the adjustment shaft 87 is engaged with the left side of the adjustment knob 89. A rotation locking portion 87a is provided on the right end of the adjustment shaft 87. The rotation locking portion 87a is provided so as to be unrotatable with respect to the spool shaft 20, and is engaged with the gear portion 55a of the lock gear 55.
[0063] The adjustment gear 81 is provided so as to be rotatable integrally with the adjustment shaft 87. A retaining ring 86 prevents the adjustment gear 81 from moving in the axial direction X relative to the adjustment shaft 87. The adjustment gear 81 moves in the axial direction X together with the adjustment shaft 87 between a disengagement position P5 where the adjustment gear 81 is separated from the drag nut 53 (restriction portion) and a coupling position P6. The adjustment gear 81 also has a gear portion 81a on its outer circumferential surface. The gear portion 81a of the adjustment gear 81 engages with the gear portion 53a of the drag nut 53 at the coupling position P6.
[0064] The adjustment knob 89 engages the adjustment shaft 87 so as to be movable in the axial direction X, and is provided on the left cover member 12B (see FIG. 8) in a state in which the adjustment shaft 87 can be adjusted and rotated. The adjustment shaft 87 is biased relative to the adjustment knob 89 from the coupling position P6 toward the disengaging position P5 by a biasing member such as a spring (not shown).
[0065] The lock gear 55 is attached to the left side surface of the flange portion 23B on the left side X2 of the spool 2, and has a gear portion 55a on its outer periphery (see FIG. 7). The rotation stop portion 87a of the adjustment shaft 87 engages with the gear portion 55a of the lock gear 55, thereby restricting the rotation of the lock gear 55 and preventing the spool shaft 20 from rotating.
[0066] To adjust the drag force of the second drag mechanism 50A configured in this manner, first, the adjustment shaft 87, which is biased by a biasing member (not shown) relative to the adjustment knob 89 toward the disconnecting position P5, is moved in the axial direction X toward the coupled position P6 against the biasing force of the biasing member. At that time, the adjustment gear 81 moves in the axial direction X together with the adjustment shaft 87 to the coupled position P6. The adjustment gear 81a is coupled to the gear portion 53a of the drag nut 53 (restriction portion).
[0067] In this state, rotating the adjustment knob 89 rotates the adjustment shaft 87, which in turn rotates the adjustment gear 81. The rotation of the adjustment gear 81 rotates the gear portion 53a of the drag nut 53, causing the drag nut 53 to advance or retreat in the axial direction X relative to the spool shaft 20, thereby adjusting the drag force.
[0068] When the adjustment shaft 87 moves to the coupling position P6, the rotation locking portion 87a of the adjustment shaft 87 engages with the gear portion 55a of the lock gear 55, restricting the rotation of the spool shaft 20. Therefore, in the second drag mechanism 50A, the drag nut 53 is able to rotate relative to the spool shaft 20, and the drag nut 53 can be advanced or retreated in the axial direction X relative to the spool shaft 20 to adjust the additional drag force as needed.
[0069] (Third embodiment) The dual-bearing reel 1B (fishing reel) according to the third embodiment shown in FIGS. 11 to 16 is configured such that the drag receiver 52 and the drag nut 53 are provided in the second braking force adjustment section 80A, whereas in the first and second embodiments described above, the second drag mechanism 50A having the drag receiver 52 and the drag nut 53 directly regulates the rotation of the spool shaft 20.
[0070] FIG. 11 is a cross-sectional view showing the second drag mechanism 50B of a dual-bearing reel 1B according to the third embodiment. FIG. 12 is a side view of the dual-bearing reel 1B shown in FIG. 11, viewed from the left side X2. FIG. 13 is a perspective view omitting the left cover member 12B and various operating sections shown in FIG. 12. FIG. 14 is a view of the second drag mechanism 50B, viewed from the right side X1 in the axial direction X. FIG. 15 is a diagram explaining the operation of the switching device of the second drag mechanism shown in FIG. 14, with (a) showing the disconnected position and (b) showing the connected position. FIG. 16 is a cross-sectional view showing the second drag mechanism 50B according to the third embodiment and the main parts of the adjustment mechanism for adjusting the drag force.
[0071] 11 and 12, the left cover member 12B is provided with the switching operation lever 73 and adjustment knob 85 of the restriction switching mechanism 70A. The switching operation lever 73 is shaped so as to be swingable about a shaft portion 73a. The adjustment knob 85 is shaped so as to be rotatable about the axial direction X.
[0072] As shown in Figures 13 and 14, the restriction switching mechanism 70A of the second drag mechanism 50B according to the third embodiment includes a switching operation lever 73 provided on the left cover member 12B (see Figures 11 and 12), a movable member 74 that swings integrally with the switching operation lever 73, a connecting gear 75 that is moved by the movable member 74 from a disconnecting position P5 (solid lines shown in Figures 13 and 14) away from the drag nut 53 (restriction portion) to a connecting position P6 (dashed two-dot lines shown in Figures 13 and 14), and a gear plate 76 that rotatably supports the connecting gear 75. In the drawing, meshing teeth (gears) provided on the outer circumferential surfaces of the shaft gear 56, connecting gear 75, and adjusting gear 81, which rotate integrally with the spool shaft 20, are omitted from the drawing.
[0073] 11 and 12, the switching operation lever 73 (adjustment switching operation portion) is biased to the disconnection position P5 (solid line in FIG. 12). As shown in FIGS. 13 and 14, the movable member 74 is formed in a substantially L-shape, and one first arm 741 is biased by a spring member 740 so that the movable member 74 is at the disconnection position P5. The other second arm 742 of the movable member 74 has a third arm 743 at the center in the longitudinal direction thereof that protrudes toward the shaft gear 56 that rotates integrally with the spool shaft 20. The third arm 743 protrudes at a right angle to the second arm 742.
[0074] 15(a) to the connecting position P6 shown in FIG. 15(b), the movable member 74 swings the connecting gear 75 in the direction of engaging with the shaft gear 56 at the second arm 742. When the movable member 74 is switched from the connecting position P6 to the disconnecting position P5, the third arm 743 swings the connecting gear 75 in the direction of moving away from the shaft gear 56, as shown in FIG. 15(a).
[0075] As shown in Figures 13 and 14, the connecting gear 75 has a gear portion 75a on its outer circumferential surface. The shaft gear 56 has a gear portion 56a on its outer circumferential surface. The connecting gear 75 is rotatably supported on one end of the gear plate 76 via a rotation shaft 75b. As described above, the connecting gear 75 is provided so as to be switchable, together with the gear plate 76, between a disengaged position P5 and a coupled position P6. The connecting gear 75 is coupled to the shaft gear 56 at the coupled position P6, and rotates together with the shaft gear 56. The connecting gear 75 also meshes with an adjusting gear 81 of a braking force adjusting unit 80, which will be described later. That is, the rotation of the connecting gear 75 coupled to the shaft gear 56 is transmitted to the adjusting gear 81. In this way, in the second drag mechanism 50B, a switching device consisting of a switching operation lever 73, a movable member 74, and a connecting gear 75 connects or disconnects the rotation of the gear portion 81a of the adjustment gear 81, whose rotation is restricted, and the shaft gear 56, which rotates integrally with the spool shaft 20.
[0076] As shown in FIG. 16, the second drag mechanism 50B includes a braking force adjusting section 80 (adjusting section) that engages with the connecting gear 75 to apply a restricting force. The braking force adjustment unit 80 includes an adjustment gear 81 that meshes with the connecting gear 75 (see FIGS. 13 and 14), a pair of a first drag plate 82A (corresponding to the "drag receiving gear 52" in the first embodiment) and a second drag plate 82B (corresponding to the "drag nut 53" in the first embodiment) that apply a drag force to the adjustment gear 81, a tubular portion 83 that fixes the first drag plate 82A, a shaft portion 84 that screws into the nut tubular portion 83 and extends parallel to the spool shaft 20, an adjustment knob 85 that is provided at one end (the end on the left side X2) of the shaft portion 84 and that rotates the shaft portion 84, and an adjustment nut 88 that is provided at the other end (the end on the right side X1) of the shaft portion 84 and screws into the tubular portion 83.
[0077] The braking force adjuster 80 restricts the rotation of the adjustment gear 81 by applying frictional force between a pair of drag plates 82A, 82B and a pair of washers 82a, 82b (corresponding to the first carbon washer 54A, the disc spring 54B, and the second carbon washer 54C in the first embodiment) made of carbon reinforced fiber or the like. In other words, drag force is added to the rotation of the spool shaft 20 as needed.
[0078] When the adjustment knob 85 of the braking force adjustment unit 80 is rotated, the adjustment nut 88 rotates together with the shaft portion 84, moving in the axial direction of the shaft portion 84 relative to the cylindrical portion 83, and adjusting the clamping force (friction force) of the pair of drag plates 82A, 82B via the disc spring 821.
[0079] In this way, in the dual-bearing reel 1B according to the third embodiment, the second drag mechanism 50B, whose drag force has been adjusted, can be connected or disconnected from the spool shaft 20 using the switching operation lever 73 of the restriction switching mechanism 70A, so that the drag force adjusted by the braking force adjustment unit 80 of the second drag mechanism 50A can be added or added as needed.
[0080] As described above, in the third embodiment, the second drag mechanism 50B is not directly mounted on the spool shaft 20, so when adjusting the drag force to be added or imparted, there is no need to fix either the spool shaft 20 or the drag nut 53 so that they cannot rotate relative to each other.
[0081] Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The embodiments and their modifications include, for example, those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are equivalent.
