Summary of the Invention
Problems to be Solved by the Invention
[0005] In a conventional double-bearing reel, when a fisherman tries to change the rotational speed of the spool while holding the handle grip, the fisherman has to release his hand from the handle grip and operate the speed change operation portion of the handle arm. For this reason, there has been a problem that it is difficult to smoothly change the rotation of the spool during the operation of the handle.
[0006] An object of the present invention is to provide a double-bearing reel capable of easily changing the rotation of the spool during the operation of the handle.
Means for Solving the Problems
[0007] A double-bearing reel according to the first aspect of the present invention comprises a reel body, a handle shaft, a spool, a transmission mechanism, a handle assembly, and a speed control mechanism.
[0008] The handle shaft is rotatably supported relative to the reel body. The spool is rotatably mounted relative to the reel body. The spool rotates in conjunction with the rotation of the handle shaft. The transmission mechanism selectively transmits the rotation of the handle shaft to the spool at a first gear ratio and at least one second gear ratio different from the first gear ratio.
[0009] The handle assembly comprises a handle arm mounted on the handle shaft and a handle grip mounted on the handle arm. The gear shift mechanism has a gear shift operating section. The gear shift operating section is used to selectively switch between the first gear ratio and the second gear ratio of the transmission mechanism. The gear shift operating section is provided on the handle grip.
[0010] In this double-bearing reel, the speed control unit is located on the handle, allowing the angler to easily operate the speed control unit while holding the handle. In other words, with this double-bearing reel, the angler can easily change the spool's rotation speed while operating the handle.
[0011] In a double-bearing reel according to a second aspect of the first aspect of the present invention, preferably, the speed change operation unit has a first operation unit for switching from a first speed ratio to a second speed ratio, and a second operation unit for switching from the second speed ratio to the first speed ratio.
[0012] In this configuration, the gear ratio is switched from the first gear ratio to the second gear ratio by operating the first control unit, and from the second gear ratio to the first gear ratio by operating the second control unit. This allows the angler to easily change the spool rotation while operating the handle.
[0013] In a double-bearing reel according to a third aspect of the second aspect of the present invention, preferably, at least one of the first operating part and the second operating part is arranged to be movable forward and backward relative to the handle grip. In this configuration, the angler can easily switch the gear ratio by moving the first operating part and / or the second operating part forward and / or backward relative to the handle grip.
[0014] In a double-bearing reel according to a fourth aspect of any one of the first to third aspects of the present invention, preferably, the speed change operating unit is arranged to be able to move forward and backward relative to the handle in a first operating state and a second operating state. The first operating state is a state in which it is possible to switch from a first speed ratio to a second speed ratio. The second operating state is a state in which it is possible to switch from a second speed ratio to a first speed ratio.
[0015] In this configuration, the angler can easily switch gear ratios by moving the gear shifting mechanism forward and backward relative to the handle.
[0016] In a double-bearing reel according to a fifth aspect that follows any one of the first to fourth aspects of the present invention, the speed change operating section preferably includes a first rack shaft, a first pinion shaft, a second rack shaft, and a second pinion shaft.
[0017] The first rack shaft is operated by the first operating section. The first rack shaft includes the first rack shaft body and the first rack gear section provided on the rack shaft body. The first pinion shaft is operated by the first rack shaft. The first pinion shaft includes the first pinion shaft body, the first pinion gear section provided on the first pinion shaft body and engaging with the first rack gear section, and the second pinion gear section provided on the first pinion shaft body.
[0018] The second rack shaft is operated by the first pinion shaft. The second rack shaft includes a second rack shaft portion, a circumferential rack portion provided on the second rack shaft portion and engaging with the second pinion gear portion, and a second rack gear portion provided on the second rack shaft portion. The second pinion shaft is operated by the second rack shaft. The second pinion shaft includes a second pinion shaft body, a third pinion gear portion provided on the second pinion shaft body and engaging with the second rack gear portion, and a fourth pinion gear portion provided on the second pinion shaft body.
[0019] In this configuration, by providing a circumferential rack section on the second rack shaft, it becomes possible to rotate the second pinion gear section around the axis center of the second rack shaft. In other words, the handle grip can be rotatably attached to the handle arm 33.
[0020] In a double-bearing reel according to a sixth aspect that follows any one of the first to fourth aspects of the present invention, the speed change mechanism preferably includes a speed change motor that selectively switches between a first speed change ratio and a second speed change ratio of the transmission mechanism in response to an operation signal from a speed change operation unit.
[0021] In this configuration, anglers can easily switch gear ratios by operating the gear shift control unit.
[0022] In a double-bearing reel according to a seventh aspect of the present invention, which follows any one of the first to sixth aspects, the transmission mechanism preferably includes a pinion gear and a drive gear. The pinion gear includes a first pinion gear and a second pinion gear different from the first pinion gear. The drive gear is provided on the handle shaft. The drive gear includes a first drive gear that meshes with the first pinion gear and a second drive gear that meshes with the second pinion gear.
[0023] The transmission mechanism selectively switches between a first transmission state and a second transmission state. The first transmission state is a state in which the rotation of the handle shaft can be transmitted to the first pinion gear via the first drive gear. The second transmission state is a state in which the rotation of the handle shaft can be transmitted to the second pinion gear via the second drive gear.
[0024] In this configuration, when the angler operates the speed change operation unit, the first transmission state and the second transmission state are selectively switched. Thereby, the speed ratio can be easily switched.

Modes for Carrying Out the Invention
[0027] Hereinafter, an embodiment of a two-bearing reel according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the two-bearing reel 1 includes a reel body 3, a spool shaft 5 (see FIG. 2), a spool 7, a handle shaft 9 (see FIG. 2), a handle assembly 11, a transmission mechanism 13 (see FIG. 2), and a speed change mechanism 15 (see FIG. 2).
[0028] In the following description, as shown in Figure 2, the first axial direction refers to the axial direction in which the first axis X1 of the spool shaft 5 extends. The first radial direction refers to the radial direction away from the first axis X1 of the spool shaft 5. The first circumferential direction refers to the circumferential direction around the first axis X1 of the spool shaft 5. The first circumferential direction includes the rotational direction of the spool shaft 5.
[0029] The second axial direction refers to the axial direction in which the second axis X2 of the handle shaft 9 extends. The second radial direction refers to the radial direction away from the second axis X2 of the handle shaft 9. The second circumferential direction refers to the circumferential direction around the second axis X2 of the handle shaft 9. The second circumferential direction includes the direction of rotation of the handle.
[0030] As shown in Figure 1, the reel body 3 has a frame 17, a first cover 19, and a second cover 21. The frame 17 has a first main body portion 17a, a second main body portion 17b, and a connecting portion 17c. The first main body portion 17a is formed in an annular shape. The second main body portion 17b is formed in an annular shape. The second main body portion 17b is positioned at a distance from the first main body portion 17a in the first axial direction. The connecting portion 17c connects the first main body portion 17a and the second main body portion 17b. The connecting portion 17c is formed integrally with the first main body portion 17a and the second main body portion 17b.
[0031] The first cover 19 covers the outer surface of the first main body portion 17a in the first axial direction. The first cover 19 is attached to the first main body portion 17a. The second cover 21 covers the outer surface of the second main body portion 17b in the first axial direction. The second cover 21 is attached to the second main body portion 17b. The second cover 21 has a first cover body 21a and a second cover body 21b. The first cover body 21a is attached to the second main body portion 17b. The second cover body 21b is attached to the first cover body 21a.
[0032] As shown in Figure 2, the spool shaft 5 has a first axis X1. The spool shaft 5 is positioned between the first cover 19 and the second cover 21 in the first axial direction. For example, the spool shaft 5 is positioned between the first cover 19 and the second cover body 21b in the first axial direction.
[0033] The spool shaft 5 is rotatably supported separately by bearings 23a and 23b on the first cover 19 and the second cover 21. For example, one end of the spool shaft 5 is rotatably supported by bearing 23a on the first cover 19. The other end of the spool shaft 5 is rotatably supported by bearing 23b on the second cover body 21b. The spool shaft 5 is supported by bearings 23a and 23b so as to be movable in the first axial direction relative to the first cover 19 and the second cover body 21b.
[0034] The spool 7 rotates in conjunction with the rotation of the handle shaft 9. As shown in Figure 2, the spool 7 is positioned between the first cover 19 and the second cover 21 in the first axial direction. One flange 7a of the spool 7 is positioned on the inner circumference of the first main body portion 17a of the frame 17. The other flange 7b of the spool 7 is positioned on the inner circumference of the second main body portion 17b of the frame 17.
[0035] The spool 7 is rotatably mounted on the reel body 3. For example, the spool 7 is rotatably supported on the spool shaft 5 via bearings 25a and 25b. The spool 7 is connected to the spool shaft 5 via a drag structure 27. The drag structure 27 is positioned between the spool shaft 5 and the spool 7.
[0036] As shown in Figure 2, the drag structure 27 includes a braking disc 27a and a friction disc 27b. The braking disc 27a is mounted on the spool shaft 5 so as to rotate integrally with the spool shaft 5. The friction disc 27b includes at least one friction disc. The friction disc 27b is positioned in the first axial direction between the side of the flange 7a of the spool 7 and the braking disc 27a.
[0037] As shown in Figures 1 and 2, the drag lever 29 is pivotably mounted on the reel body 3. For example, the drag lever 29 is pivotably mounted on the second cover 21. For example, the drag lever 29 is pivotably mounted on the second cover body 21b. By pivoting the drag lever 29 relative to the second cover body 21b, the spool shaft 5 and the braking disc 27a reciprocate in the first axial direction via the moving mechanism 31 shown in Figure 2.
[0038] The moving mechanism 31 moves the spool shaft 5 and the braking disc 27a in a first axial direction away from the drag lever 29 and in a first axial direction approaching the drag lever 29, according to the direction of oscillation of the drag lever 29.
[0039] For example, if the damping disc 27a moves in the first axial direction toward the drag lever 29 due to the oscillation of the drag lever 29, the damping disc 27a will move toward the flange 7a of the spool 7. In this case, the pressure force of the friction disc 27b against the flange 7a of the spool 7 will increase. As a result, the rotation of the spool shaft 5 is transmitted to the spool 7 via the friction disc 27b.
[0040] When the braking disc 27a moves in the first axial direction away from the drag lever 29 due to the oscillation of the drag lever 29, the braking disc 27a moves away from the flange 7a of the spool 7. In this case, the pressure force of the friction disc 27b against the flange 7a of the spool 7 decreases. When the braking disc 27a moves away from the friction disc 27b, the rotation of the spool shaft 5 is not transmitted to the spool 7, and the spool 7 rotates freely.
[0041] As shown in Figure 2, the handle shaft 9 has a second axis X2. The second axis X2 is positioned parallel to the first axis X1 of the spool shaft 5. That is, the handle shaft 9 is positioned parallel to the spool shaft 5. The handle shaft 9 is rotatably supported relative to the reel body 3. For example, the handle shaft 9 is rotatably supported relative to the second cover body 21b of the second cover 21. The handle shaft 9 is formed in a cylindrical shape. The operating shaft 51 of the switching structure 41, which will be described later, is positioned on the inner circumference of the handle shaft 9.
[0042] As shown in Figure 2, the handle assembly 11 is mounted on the handle shaft 9. For example, the handle assembly 11 has a handle arm 33 and a handle grip 35. The handle arm 33 is mounted on the handle shaft 9. For example, the handle arm 33 is mounted integrally with the handle shaft 9 so as to be rotatable.
[0043] The handle grip 35 is attached to the handle arm 33. The handle grip 35 is rotatably mounted on the handle arm 33 about a second rack shaft 65, which will be described later. In detail, the handle grip 35 includes a gripping portion 35a and a connecting portion 35b, and rotates around the second rack shaft 65 via a bearing 69a, with the second rack shaft 65 passing through the connecting portion 35b. The gripping portion 35a is the part that is gripped by the angler. The connecting portion 35b protrudes from the gripping portion 35a and is positioned between the gripping portion 35a and the handle arm 33.
[0044] The transmission mechanism 13 shown in Figures 2 and 3 selectively transmits the rotation of the handle shaft 9 to the spool 7 at a first gear ratio and a second gear ratio different from the first gear ratio. As shown in Figures 2 and 3, the transmission mechanism 13 includes a transmission gear 37, a drive gear 39, and a switching structure 41.
[0045] As shown in Figure 2, the transmission gear 37 is mounted on the spool shaft 5. The transmission gear 37 includes a first transmission gear 37a and a second transmission gear 37b. The first transmission gear 37a is formed in a cylindrical shape. The first transmission gear 37a is mounted on the outer circumferential surface of the spool shaft 5 so as to rotate integrally with the spool shaft 5.
[0046] The second transmission gear 37b is different from the first transmission gear 37a. The second transmission gear 37b is formed with a larger diameter than the first transmission gear 37a. The second transmission gear 37b is formed in a cylindrical shape. The second transmission gear 37b is arranged side by side with the first transmission gear 37a in the first axial direction. The second transmission gear 37b is mounted on the outer circumferential surface of the first transmission gear 37a so as to rotate integrally with the spool shaft 5. The second transmission gear 37b may also be mounted on the outer circumferential surface of the spool shaft 5 so as to rotate integrally with the spool shaft 5.
[0047] As shown in Figures 2 and 3, the drive gear 39 is mounted on the handle shaft 9. The drive gear 39 includes a first drive gear 39a and a second drive gear 39b. The first drive gear 39a is a drive gear for high-speed winding. The first drive gear 39a is rotatably mounted on the handle shaft 9. The first drive gear 39a meshes with the first transmission gear 37a. The gear ratio of the first drive gear 39a and the first transmission gear 37a determines the first gear ratio.
[0048] The second drive gear 39b is a drive gear for low-speed winding. The second drive gear 39b is formed to have a smaller diameter than the first drive gear 39a. The second drive gear 39b is rotatably mounted on the handle shaft 9. The second drive gear 39b meshes with the second transmission gear 37b. The second drive gear 39b is different from the first drive gear 39a. The gear ratio of the second drive gear 39b and the second transmission gear 37b determines the second gear ratio.
[0049] As shown in Figure 3, a first positioning member 43a is attached to the tip of the handle shaft 9. The first positioning member 43a positions the second drive gear 39b relative to the handle shaft 9. The second positioning member 43b is positioned between the first drive gear 39a and the second drive gear 39b in the second axial direction. The second positioning member 43b positions the first drive gear 39a relative to the second drive gear 39b. As a result, the first drive gear 39a and the second drive gear 39b are positioned with a gap between them in the second axial direction and are positioned relative to the handle shaft 9.
[0050] As shown in Figure 3, the switching structure 41 is used to engage the engaging piece 45 with the first drive gear 39a or the second drive gear 39b. The switching structure 41 is located on the handle shaft 9. For example, the switching structure 41 is located between the second main body portion 17b of the frame 17 and the handle assembly 11.
[0051] The switching structure 41 includes an engaging piece 45, a first biasing member 47, a second biasing member 49, and an operating shaft 51. The engaging piece 45 is positioned between the frame 17 and the operating shaft 51 in the second axial direction. For example, the engaging piece 45 is positioned between the second main body portion 17b of the frame 17 and the operating shaft 51 in the second axial direction.
[0052] The engaging piece 45 is mounted on the handle shaft 9 so as to rotate integrally with the handle shaft 9. The engaging piece 45 is mounted on the handle shaft 9 so as to move in the second axial direction relative to the handle shaft 9. For example, as shown in Figure 3, the engaging piece 45 is positioned inside a slit 9a that extends in the second axial direction on the handle shaft 9. The engaging piece 45 moves in the second axial direction along the slit 9a.
[0053] The engaging piece 45 selectively engages with the first drive gear 39a and the second drive gear 39b. The engagement of the engaging piece 45 with the first drive gear 39a and the engagement of the engaging piece 45 with the second drive gear 39b are selected by the movement of the operating shaft 51, which will be described later.
[0054] Figure 3 shows the state in which the engaging piece 45 is engaged with the first drive gear 39a. When the engaging piece 45 is engaged with the first drive gear 39a, the first drive gear 39a rotates integrally with the handle shaft 9. In this case, the first transmission gear 37a rotates together with the first drive gear 39a. With this configuration, the rotation of the handle shaft 9 is transmitted to the first transmission gear 37a via the first drive gear 39a. This state is the first transmission state.
[0055] In the first transmission state, the first drive gear 39a rotates while meshed with the first transmission gear 37a, causing the spool 7 to rotate at high speed via the spool shaft 5 and the drag structure 27.
[0056] When the engaging piece 45 moves in the second axial direction (to the left in Figure 3) due to the movement of the operating shaft 51 and engages with the second drive gear 39b, the second drive gear 39b rotates integrally with the handle shaft 9. In this case, the second transmission gear 37b rotates together with the second drive gear 39b. With this configuration, the rotation of the handle shaft 9 is transmitted to the second transmission gear 37b via the second drive gear 39b. This state is the second transmission state.
[0057] In the second transmission state, the second drive gear 39b rotates while meshed with the second transmission gear 37b, causing the spool 7 to rotate at a low speed via the spool shaft 5 and the drag structure 27. In this way, the transmission mechanism 13 selectively switches between the first transmission state and the second transmission state via the engaging piece 45.
[0058] As shown in Figure 3, the first biasing member 47 is positioned in a compressed state between the spring holding member 44 and the second axial direction of the engaging piece 45. The second biasing member 49 is positioned in a compressed state between the engaging piece 45 and the second axial direction of the tip of the operating shaft 51. The engaging piece 45 is positioned between the first biasing member 47 and the second biasing member 49 in the second axial direction.
[0059] In this state, the operating shaft 51 is biased in the second axial direction away from the spring holding member 44 by the first biasing member 47 and the second biasing member 49. The first biasing member 47 and the second biasing member 49 are, for example, coil springs.
[0060] As shown in Figure 3, the operating shaft 51 is used to move the engaging piece 45. The operating shaft 51 is located on the inner circumference of the handle shaft 9. For example, the operating shaft 51 moves in the second axial direction relative to the handle shaft 9 on the inner circumference of the handle shaft 9 in accordance with the operation of the transmission mechanism 15, which will be described later.
[0061] When the engaging piece 45 is engaged with the first drive gear 39a, if the operating shaft 51 moves in the second axial direction toward the spring retaining member 44, the engaging piece 45 is biased toward the spring retaining member 44 by the second biasing member 49. As a result, the engaging piece 45 moves toward the spring retaining member 44 and engages with the second drive gear 39b. When the engaging piece 45 is engaged with the second drive gear 39b, as described above, the rotation of the handle shaft 9 is transmitted to the second transmission gear 37b via the second drive gear 39b.
[0062] When the engaging piece 45 is engaged with the second drive gear 39b, if the operating shaft 51 moves in the second axial direction toward the handle assembly 11, the engaging piece 45 is biased toward the handle assembly 11 by the first biasing member 47. As a result, the engaging piece 45 moves toward the spring holding member 44, and the engaging piece 45 engages with the first drive gear 39a. When the engaging piece 45 is engaged with the first drive gear 39a, as described above, the rotation of the handle shaft 9 is transmitted to the first transmission gear 37a via the first drive gear 39a.
[0063] As shown in Figure 4, the gear shift mechanism 15 includes a gear shift operating unit 53, a locking member 55, a first operating structure 57, and a second operating structure 59. The gear shift mechanism 15 may also include an operating shaft 51. The gear shift operating unit 53 is used to selectively switch between the first gear ratio and the second gear ratio of the transmission mechanism 13. For example, the gear shift operating unit 53 selectively switches between the first gear ratio and the second gear ratio by operating the switching structure 41 described above.
[0064] As shown in Figure 1, the gear shift operation unit 53 is provided on the handle grip 35. The gear shift operation unit 53 has a first operation button 53a (an example of the first operation unit) and a second operation button 53b (an example of the first operation unit).
[0065] The first operation button 53a is used to switch from the first gear ratio of the transmission mechanism 13 to the second gear ratio of the transmission mechanism 13. The first operation button 53a is positioned to move forward and backward relative to the handle grip 35. For example, as shown in Figure 4, the first operation button 53a is fixed to the first rack shaft 61, which will be described later. The first operation button 53a is positioned to move forward and backward relative to the handle grip 35 together with the first rack shaft 61.
[0066] The second operation button 53b is used to switch from the second gear ratio of the transmission mechanism 13 to the first gear ratio of the transmission mechanism 13. The second operation button 53b is positioned to move forward and backward relative to the handle grip 35. For example, as shown in Figure 4, the second operation button 53b is fixed to the locking member 55. The second operation button 53b, together with the locking member 55, is positioned to move forward and backward relative to the handle grip 35.
[0067] The locking member 55 is positioned on the gripping portion 35a. As shown in Figure 4, the locking member 55 engages with the first rack shaft 61, which will be described later. As shown in Figure 5, the locking member 55 has a first hole 56 and a second hole 58. The first rack shaft 61 is inserted through the first hole 56. An engaging portion 56a is formed in the first hole 56. The engaging portion 56a engages with the engaging recess 61c of the first rack shaft 61. The engaging recess 61c is a groove formed on the outer circumferential surface of the first rack shaft 61.
[0068] When the engaging portion 56a is engaged with the engaging recess 61c, the first operation button 53a, which is fixed to the first rack shaft 61, is in a non-pressable state. The second operation button 53b is in a pressable state. When the engaging portion 56a and the engaging recess 61c are released, the first operation button 53a is in a pressed state, and the second operation button 53b is in a non-pressable state.
[0069] A contact portion 35c, provided on the gripping portion 35a, is positioned on the inner circumference of the second hole 58. A projection 58a for holding the spring member 60 is formed in the second hole 58. One end of the spring member 60 is positioned on the outer circumference of the projection 58a. The other end of the spring member 60 contacts the contact portion 35c. As a result, the locking member 55 and the second operating button 53b are biased by the spring member 60 in a direction away from the contact portion 35c of the gripping portion 35a.
[0070] As shown in Figure 2, the first operating structure 57 is located inside the gripping section 35a. As shown in Figure 4, the first operating structure 57 includes a first rack shaft 61 and a first pinion shaft 63. As shown in Figure 2, the first rack shaft 61 is located inside the gripping section 35a. The first rack shaft 61 is operated by a first operating button 53a. For example, the first rack shaft 61 is moved by the operation of the first operating button 53a.
[0071] As shown in Figure 4, the first rack shaft 61 includes a first rack shaft body 61a, a first rack gear portion 61b, and an engagement recess 61c. The first rack shaft body 61a is a shaft member that is long in one direction. One end of the first rack shaft body 61a is fixed to the first operating button 53a. The first rack gear portion 61b is provided at the other end of the first rack shaft body 61a.
[0072] The engaging recess 61c of the first rack shaft 61 shown in Figure 5 is provided on the outer circumferential surface of the first rack shaft body 61a, between one end of the first rack shaft body 61a and the first rack gear portion 61b. The engaging portion 56a of the locking member 55 engages with the engaging recess 61c of the first rack shaft 61.
[0073] As shown in Figure 2, the first pinion shaft 63 is located inside the gripping portion 35a. The first pinion shaft 63 is operated by the first rack shaft 61. For example, the first pinion shaft 63 rotates as the first rack shaft 61 moves. As shown in Figure 4, the first pinion shaft 63 includes a first pinion shaft body 63a, a first pinion gear portion 63b, and a second pinion gear portion 63c.
[0074] The first pinion shaft body 63a is a shaft member that is elongated in one direction. The first pinion shaft body 63a is rotatably supported on the inner surface of the gripping portion 35a via bearings 64a and 64b. The first pinion gear portion 63b is provided at one end of the first pinion shaft body 63a. The first pinion gear portion 63b engages with the first rack gear portion 61b. For example, the first pinion gear portion 63b meshes with the first rack gear portion 61b. The second pinion gear portion 63c is provided at the other end of the first pinion shaft body 63a.
[0075] As shown in Figure 4, the second operating structure 59 includes a second rack shaft 65 and a second pinion shaft 67. As shown in Figure 2, the second rack shaft 65 is located inside the handle grip 35 and the handle arm 33. The second rack shaft 65 is operated by the first pinion shaft 63. For example, the second rack shaft 65 is moved by the rotation of the first pinion shaft 63.
[0076] As shown in Figure 4, the second rack shaft 65 includes a second rack shaft body 65a, a circumferential rack portion 65b, and a second rack gear portion 65c. The second rack shaft body 65a is a shaft member that is elongated in one direction. As shown in Figure 2, the second rack shaft body 65a supports the inner surface of the gripping portion 35a via a bearing 69a.
[0077] More specifically, a boss member 66 is positioned between the second rack shaft body 65a and the inner surface of the gripping portion 35a. The second rack shaft body 65a is inserted through the inner circumference of the boss member 66. A bearing 69a is positioned between the boss member 66 and the inner surface of the gripping portion 35a.
[0078] As shown in Figure 4, the circumferential rack portion 65b is provided at one end of the second rack shaft body 65a. Multiple rack teeth are formed on the outer circumferential surface of one end of the second rack shaft body 65a in the circumferential rack portion 65b. The circumferential rack portion 65b engages with the second pinion gear portion 63c. The second rack gear portion 65c is provided at the other end of the second rack shaft body 65a.
[0079] As described above, the second rack shaft 65 is provided with a circumferential rack portion 65b, so that the first pinion shaft 63 (first pinion shaft body 63a) can rotate around the second rack shaft 65 (second rack shaft body 65a) with the second rack shaft 65 (second rack shaft body 65a) as its center, while the second pinion gear portion 63c is engaged with the circumferential rack portion 65b. With this configuration, the handle grip 35 is rotatably mounted on the handle arm 33.
[0080] As shown in Figure 2, the second pinion shaft 67 is located inside the handle arm 33. The second pinion shaft 67 is operated by the second rack shaft 65. For example, the second pinion shaft 67 rotates as the second rack shaft 65 moves. The second pinion shaft 67 is also operated by the operating shaft 51. For example, the second pinion shaft 67 rotates as the operating shaft 51 moves.
[0081] As shown in Figure 4, the second pinion shaft 67 engages with the operating shaft 51. Rotation of the second pinion shaft 67 causes the operating shaft 51 to move in the second axial direction. The second pinion shaft 67 includes a second pinion shaft body 67a, a third pinion gear portion 67b, and a fourth pinion gear portion 67c.
[0082] The second pinion shaft body 67a is a shaft member that is elongated in one direction. The second pinion shaft body 67a is rotatably supported on the inner surface of the handle arm 33 via bearings 68a and 68b. The third pinion gear portion 67b is provided at one end of the second pinion shaft body 67a. The third pinion gear portion 67b engages with the second rack gear portion 65c. For example, the third pinion gear portion 67b meshes with the second rack gear portion 65c. The fourth pinion gear portion 67c is provided at the other end of the second pinion shaft body 67a. The fourth pinion gear portion 67c is connected to the operating shaft 51.
[0083] In detail, the operating shaft 51 includes an operating shaft body 51a and a third rack gear section 51b. The operating shaft body 51a is a shaft member that is elongated in one direction. The third rack gear section 51b is provided at one end of the operating shaft body 51a. As shown in Figure 3, the third rack gear section 51b protrudes from the handle shaft 9 in the second axial direction. The third rack gear section 51b meshes with the fourth pinion gear section 67c.
[0084] When the above-described gear shifting mechanism 15 is in operation, the above-described switching structure 41 operates as follows. When the engaging piece 45 of the switching structure 41 is engaged with the first drive gear 39a (the state in Figure 3), the engaging portion 56a of the locking member 55 shown in Figure 5 and the engaging recess 61c of the first rack shaft 61 are released. In this state, the first operation button 53a is in a pressed state, and the second operation button 53b is in an unpressable state.
[0085] First, when the first operation button 53a of the gear shift operation unit 53 is pressed, the first rack shaft 61 of the first operation structure 57 moves in the pressing direction, and the first pinion shaft 63 of the first operation structure 57 rotates. At this time, the engaging portion 56a of the locking member 55 of the gear shift mechanism 15 engages with the engaging recess 61c of the first rack shaft 61. As a result, the first operation button 53a becomes unpressable, and the second operation button 53b becomes pressable.
[0086] Next, the rotation of the first pinion shaft 63 causes the second rack shaft 65 of the second operating structure 59 to move toward the reel body 3, and the second pinion shaft 67 of the second operating structure 59 rotates. This rotation of the second pinion shaft 67 causes the operating shaft 51 to move toward the second axial direction toward the spring retaining member 44. As a result, the engaging piece 45 is pressed by the second biasing member 49 and engages with the second drive gear 39b. In this state, when the handle assembly 11 rotates, the handle shaft 9, the engaging piece 45, and the second drive gear 39b rotate. In this case, the spool 7 rotates at a low speed.
[0087] Next, when the second operation button 53b of the gear shift operation unit 53 is pressed, the engagement of the engaging portion 56a of the locking member 55 and the engaging recess 61c of the first rack shaft 61 is released. In this state, the second operation button 53b cannot be pressed. With the engagement of the engaging portion 56a of the locking member 55 and the engaging recess 61c of the first rack shaft 61 released, the engaging piece 45 is pressed by the first biasing member 47 and engages with the first drive gear 39a. Subsequently, the operating shaft 51 is pressed by the second biasing member 49 and moves in the second axial direction away from the spring holding member 44.
[0088] The movement of the operating shaft 51 causes the second pinion shaft 67 to rotate, and the second rack shaft 65 to move away from the reel body 3. As a result, the first pinion shaft 63 rotates, and the first rack shaft 61 moves in the opposite direction to the pressing direction described above. This movement of the first rack shaft 61 returns the first operating button 53a from an unpressable state to an pressable state. In this state, when the handle assembly 11 rotates, the handle shaft 9, the engaging piece 45, and the first drive gear 39a rotate. In this case, the spool 7 rotates at high speed.
[0089] In the double-bearing reel 1 described above, the first operation button 53a and the second operation button 53b are provided on the handle grip 35, so the angler can easily operate the first operation button 53a and the second operation button 53b while holding the handle grip 35. In other words, with the double-bearing reel 1, the angler can easily change the rotation of the spool 7 while operating the handle.
[0090] (modified version) Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the invention.
[0091] • Variation 1 The gear shift operation unit 53 of the above embodiment may be configured as follows. As shown in Figure 6, the gear shift operation unit 53 includes a third operation button 153a. The third operation button 153a is positioned to be movable forward and backward relative to the handle grip 35.
[0092] By operating the third operation button 153a, the third operation button 153a can be switched between the first operation state and the second operation state. The first operation state is a state in which it is possible to switch from the first gear ratio to the second gear ratio. The second operation state is a state in which it is possible to switch from the second gear ratio to the first gear ratio.
[0093] For example, the third operation button 153a is connected to the first rack shaft 61 via a press / return mechanism 154, similar to that of a retractable ballpoint pen. In the first operating state, where the third operation button 153a protrudes from the gripping portion 35a of the handle handle 35, when the third operation button 153a is pressed, the operating state of the third operation button 153a changes to a second operating state, where it approaches the gripping portion 35a of the handle handle 35.
[0094] With the engaging piece 45 shown in Figure 3 engaged with the first drive gear 39a, when the operating state of the third operation button 153a changes from the first operating state to the second operating state, the gear shift mechanism 15 and the switching structure 41 operate in the same manner as in the above embodiment, and the engaging piece 45 engages with the second drive gear 39b.
[0095] In this state, when the third operation button 153a is pressed again, the operating state of the third operation button 153a returns from the second operating state to the first operating state. In this case, the gear shifting mechanism 15 and the switching structure 41 operate in the same manner as in the above embodiment, and the engaging piece 45 engages with the first drive gear 39a. Even with this configuration, the same effects as in the above embodiment can be obtained.
[0096] • Variation 2 The gear shift mechanism 15 of the above embodiment may be configured as follows. The gear shift mechanism 115 shown in Figure 7 selectively switches the first gear ratio and the second gear ratio of the transmission mechanism 13 based on an operation signal from the gear shift operation unit 53.
[0097] For example, the transmission mechanism 115 includes transmitting units 155a and 155b, a receiving unit 156, a transmission motor 157, a cam member 158, and a connecting belt 159. The transmitting units 155a and 155b are provided on the handle grip 35. The receiving unit 156, the transmission motor 157, the cam member 158, and the connecting belt 159 are provided on the handle arm 33.
[0098] The speed control motor 157 rotates when the first operation button 53a or the second operation button 53b is pressed. By rotating the speed control motor 157, the cam member 158 rotates via the connecting belt 159. The cam member 158 is positioned opposite the end of the operating shaft 51 in the second axial direction. The connecting belt 159 is stretched between the motor shaft of the speed control motor 157 and the cam member 158.
[0099] When the first operation button 53a is pressed, a first operation signal for controlling the rotation of the speed change motor 157 is transmitted from the transmitting unit 155a to the receiving unit 156. This first operation signal causes the speed change motor 157 to rotate, and the cam member 158 rotates via the connecting belt 159. As a result, the operating shaft 51 approaches the spring retaining member 44, and the engaging piece 45 engages with the second drive gear 39b.
[0100] When the second operation button 53b is pressed, a second operation signal for controlling the rotation of the speed change motor 157 is transmitted from the transmitting unit 155b to the receiving unit 156. This second operation signal causes the speed change motor 157 to rotate, and the cam member 158 rotates via the connecting belt 159. As a result, the operating shaft 51 separates from the spring retaining member 44, and the engaging piece 45 engages with the first drive gear 39a. Even with this configuration, the same effects as in the above embodiment can be obtained.
[0101] (Other embodiments) (A) In the above embodiment, an example is shown in which the transmission mechanism 13 has one second gear ratio. The second gear ratio may have multiple second gear ratios. The multiple second gear ratios are different gear ratios from each other.
[0102] In this case, multiple second transmission gears 37b and multiple second drive gears 39b are provided. Multiple second transmission gears 37b and multiple second drive gears 39b are formed such that the gear ratio of each second transmission gear 37b and each second drive gear 39b that meshes with each second transmission gear 37b is different. This configuration makes it possible to realize multiple second gear ratios.
[0103] (B) In the above embodiment, an example is shown in which the circumferential rack portion 65b of the second rack shaft 65 is provided at one end of the second rack shaft body 65a, and the second rack gear portion 65c of the second rack shaft 65 is provided at the other end of the second rack shaft body 65a.
[0104] The positions in which the circumferential rack portion 65b is provided on the second rack shaft body 65a and the positions in which the second rack gear portion 65c is provided on the second rack shaft body 65a may be swapped. For example, the second rack gear portion 65c may be provided at one end of the second rack shaft body 65a, and the circumferential rack portion 65b may be provided at the other end of the second rack shaft body 65a.
[0105] In this case, the second rack gear portion 65c engages with the second pinion gear portion 63c. The circumferential rack portion 65b engages with the third pinion gear portion 67b. Even with this configuration, the same effects as in the above embodiment can be obtained. [Explanation of Symbols]
