Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional two-bearing reel, for example, a boss portion for guiding the swing of a clutch operation member is press-fitted into a hole portion of a first side plate of a frame. In this case, in the process of forming a hole portion in the first side plate of the frame and / or the process of fitting and bonding the boss portion to the hole portion, the first side plate of the frame may be deformed. As a result, there is a possibility that the accuracy of the frame desired by the designer cannot be sufficiently ensured.

[0005] An object of the present invention is to provide a two-bearing reel capable of improving the accuracy of a frame.

Means for Solving the Problems

[0006] Regarding a first aspect of the present invention, the double bearing reel comprises a frame, a clutch operating member, a side cover, and a boss portion. The frame has a first side plate and a second side plate facing the first side plate. The first side plate has an inner surface facing the second side plate, an outer surface opposite to the second side plate, and a hole extending from the outer surface toward the inner surface.

[0007] The clutch operating member is positioned between the first side plate and the second side plate. The clutch operating member swings relative to the first side plate and the second side plate. The side cover is attached to the first side plate on the side opposite to the second side plate. The boss portion is provided on the side cover between the first side plate and the side cover. The tip of the boss portion is inserted into a hole in the first side plate and protrudes from the inner surface. The tip of the boss portion guides the swing of the clutch operating member.

[0008] In the first aspect of the double bearing reel of the present invention, a boss portion is provided on the side cover, and the tip of the boss portion guides the oscillation of the clutch operating member. In this configuration, since the boss portion is not directly provided on the first side plate, the precision of the frame can be improved compared to the conventional configuration.

[0009] With respect to a second aspect of the present invention, the two bearing reels relating to the first aspect may be configured as follows: The boss portion is formed integrally with the side cover.

[0010] In the double bearing reel relating to the second aspect of the present invention, the boss portion is formed integrally with the side cover, thereby ensuring the rigidity of the boss portion.

[0011] With respect to a third aspect of the present invention, the two bearing reels relating to the first aspect may be configured as follows: The boss portion is formed separately from the side cover.

[0012] In the double bearing reel according to the third aspect of the present invention, the boss portion is formed separately from the side cover, which improves the ease of assembly of the boss portion.

[0013] With respect to a fourth aspect of the present invention, the bearing reels relating to the first or third aspect may be configured as follows: The boss portion is formed in a cylindrical shape. A reinforcing member is arranged on the inner circumference of the boss portion.

[0014] In the double bearing reel according to the fourth aspect of the present invention, the reinforcing member is arranged on the inner circumference of the boss portion, thereby improving the rigidity and strength of the boss portion.

[0015] With respect to a fifth aspect of the present invention, the double bearing reel relating to the first aspect may be configured as follows: The clutch operating member has a lever body and a recess. The recess is provided in the lever body and extends in the direction in which the lever body swings. The tip of the boss portion is positioned in the recess.

Embodiment for Carrying Out the Invention

[0019] As shown in FIG. 1, the two-bearing reel 1 adopting one embodiment of the present invention includes a reel body 3 that can be attached to a fishing rod, a handle 4 for spool rotation disposed on the side of the reel body 3, and a spool 7 rotatably attached to the reel body 3. As shown in FIG. 2, the two-bearing reel 1 further includes a rotation transmission mechanism 13, a clutch mechanism 25, and a clutch control device 30. As shown in FIG. 3, the two-bearing reel further includes a clutch operation member 11 (an example of a clutch operation member) and a boss portion 50.

[0020] Hereinafter, as shown in FIGS. 1 to 3, the rotation axis of the spool 7 is denoted as the spool axis X. Also, the direction in which the spool axis X extends and the direction along the spool axis X are denoted as the axial direction, and the direction around the spool axis X centered on the spool axis X is denoted as the circumferential direction (rotation direction). Further, the direction away from the spool axis X centered on the spool axis X is denoted as the radial direction.

[0021] <Reel body> As shown in FIGS. 1 and 2, the reel body 3 includes a frame 5, a first side cover 6a and a second side cover 6b attached to cover both sides of the frame 5, and a front cover 8 (see FIG. 1) attached to the front of the frame 5.

[0022] As shown in FIG. 4, the frame 5 supports the handle shaft 17. As shown in FIGS. 2 and 3, the frame 5 has a first side plate 9a and a second side plate 9b disposed opposite to each other with a gap therebetween. The first side plate 9a and the second side plate 9b are connected by a connecting portion 9c. As shown in FIG. 2, the first side plate 9a has a first opening 9d. A bearing housing portion 16 is fixed to the first opening 9d.

[0023] As shown in Figure 3, the first side plate 9a has an inner surface 9a1, an outer surface 9a2, and a hole 9a3. The inner surface 9a1 is the surface facing the second side plate 9b. The outer surface 9a2 is the surface opposite to the second side plate 9b. The hole 9a3 extends from the outer surface 9a2 toward the inner surface 9a1. The hole 9a3 penetrates the first side plate 9a.

[0024] As shown in Figure 2, a clutch control device 30 (see Figure 3) is mounted on the second side plate 9b. The second side plate 9b has a second opening 9e through which the spool shaft 15 passes. As shown in Figures 2 and 3, the first side cover 6a is mounted on the first side plate 9a of the frame 5. As shown in Figures 2 and 3, the first side cover 6a is mounted on the first side plate 9a on the opposite side from the second side plate 9b. As shown in Figure 2, the second side cover 6b is mounted on the second side plate 9b of the frame 5.

[0025] <Spool> As shown in Figures 2 and 4, the spool 7 is rotatably positioned between the first side plate 9a and the second side plate 9b. The spool 7 is attached to the spool shaft 15 so as to be able to rotate integrally with the spool shaft 15. The spool shaft 15 is rotatably supported relative to the reel body 3. The axis of the spool shaft 15 is concentric with the spool axis X. For example, one end of the spool shaft 15 is rotatably supported relative to the first side plate 9a via a bearing 18a located in the bearing housing 16. The other end of the spool shaft 15 is rotatably supported by the second side cover 6b via a bearing 18b. An engagement pin 15a, which constitutes the clutch mechanism 25, is mounted on the spool shaft 15.

[0026] <Rotational transmission mechanism> The rotation transmission mechanism 13 shown in Figures 2 and 4 is for transmitting rotational force from the handle 4 to the spool 7. As shown in Figure 2, the rotation transmission mechanism 13 is located between the frame 5 and the second side cover 6b. As shown in Figure 4, for example, the rotation transmission mechanism 13 includes a handle shaft 17, a drag mechanism 19, a drive gear 21, and a pinion gear 23.

[0027] As shown in Figure 2, the handle 4 is mounted on the handle shaft 17. The handle shaft 17 is rotatably supported by the second side cover 6b and the frame 5. As shown in Figure 4, the drag mechanism 19 transmits the rotation of the handle shaft 17 to the drive gear 21 and also brakes the rotation of the spool 7 when the line is being dispensed. The drag mechanism 19 is positioned between the handle shaft 17 and the drive gear 21.

[0028] As shown in Figure 4, the drive gear 21 is rotatably mounted on the handle shaft 17. The rotation of the handle shaft 17 is transmitted to the drive gear 21 via the drag mechanism 19. When a torque exceeding a predetermined level is applied to the spool 7 during line payout, the drag mechanism 19 activates, causing the drive gear 21 to rotate relative to the handle shaft 17.

[0029] As shown in Figure 2, the pinion gear 23 is formed in a substantially cylindrical shape. The pinion gear 23 is positioned radially outward of the spool shaft 15 so that it can move axially relative to the spool shaft 15. The pinion gear 23 is positioned radially outward of the spool shaft 15 so that it can rotate circumferentially with the spool shaft 15 via the clutch mechanism 25. The axis of the pinion gear 23 is concentric with the spool axis X.

[0030] The pinion gear 23 is rotatably supported on the second side cover 6b via a bearing 18c. The pinion gear 23 is rotatably supported on the second side plate 9b via a bearing 18d. As shown in Figures 2 and 4, the pinion gear 23 meshes with the drive gear 21 and transmits the rotation of the drive gear 21 to the spool shaft 15 via a clutch mechanism 25.

[0031] <Clutch mechanism> The clutch mechanism 25 is configured to be able to connect the handle 4 and the spool 7, and to be able to disconnect the handle 4 and the spool 7. As shown in Figure 2, the clutch mechanism 25 is composed of an engagement groove 23a of the pinion gear 23 and an engagement pin 15a of the spool shaft 15.

[0032] For example, when the pinion gear 23 moves along the spool shaft 15 away from the spool 7, the engagement groove 23a and the engagement pin 15a of the spool shaft 15 are released. This releases the connection between the spool shaft 15 and the pinion gear 23, resulting in a clutch-off state (disconnected state). In this case, the spool 7 becomes free to rotate.

[0033] On the other hand, when the pinion gear 23 moves along the spool shaft 15 toward the spool 7, the engagement groove 23a engages with the engagement pin 15a. This connects the spool shaft 15 and the pinion gear 23, resulting in a clutch-on state (connected state). In this case, the spool 7 rotates in conjunction with the rotation of the handle shaft 17.

[0034] <Clutch control device> As shown in Figures 2 and 4, the clutch control device 30 is configured to control the clutch mechanism 25 in response to the operation of the clutch operating member 11. As shown in Figure 2, the clutch control device 30 is positioned between the frame 5 and the second side cover 6b.

[0035] As shown in Figures 2 and 4, the clutch control device 30 includes a clutch support member 46, a clutch yoke 41, a clutch cam 43, and a connecting member 42.

[0036] The clutch support member 46 is mounted on the frame 5, for example, the second side plate 9b. The clutch support member 46 supports the clutch yoke 41 so that it can move in the axial direction. The clutch support member 46 supports the clutch cam 43 so that it can rotate in the circumferential direction.

[0037] The clutch yoke 41 is supported by a pair of guide portions 46a of the clutch support member 46. The clutch yoke 41 moves axially along the pair of guide portions 46a of the clutch support member 46. The clutch yoke 41 engages with the pinion gear 23, causing the pinion gear 23 to move axially along the spool shaft 15. This movement of the pinion gear 23 switches the clutch mechanism 25 between the clutch-on state and the clutch-off state.

[0038] As shown in Figure 2, a coil spring 44 is positioned between the clutch yoke 41 and the second side cover 6b. The coil spring 44 is positioned on the outer circumference of each guide portion 46a in a compressed state.

[0039] As shown in Figures 2 and 4, the clutch cam 43 is positioned on the clutch support member 46 so as to be rotatable around the spool axis X. The rotation of the clutch cam 43 causes the clutch yoke 41 to move axially.

[0040] As shown in Figures 2 to 4, the connecting member 42 connects the clutch operating member 11 and the clutch cam 43. The connecting member 42 is mounted on the clutch cam 43. As shown in Figure 2, the connecting member 42 is positioned axially between the clutch cam 43 and the clutch support member 46. As shown in Figures 3 and 4, the clutch operating member 11 is attached to the connecting member 42 via a fixing member, such as a screw member 60.

[0041] <Clutch operating member and boss portion> As shown in Figures 1 and 3, the clutch operating member 11 is located at the rear of the reel body 3. The clutch operating member 11 is connected to the clutch cam 43 (see Figure 4) of the clutch control device 30 via a connecting member 42.

[0042] The clutch operating member 11 is used as a thumb rest during thumbing. The clutch operating member 11 is used for switching the clutch mechanism 25. The clutch operating member 11 is configured to swing between the clutch-on position shown in Figure 1 and the clutch-off position located below in Figure 1.

[0043] The pivot point of the clutch operating member 11 is concentric with the pivot points of the clutch cam 43 and the connecting member 42. In other words, the pivot point of the clutch operating member 11 is concentric with the spool axis X.

[0044] As shown in Figure 1, the clutch operating member 11 is positioned between the first side plate 9a and the second side plate 9b. The clutch operating member 11, together with the connecting member 42, swings relative to the first side plate 9a and the second side plate 9b. The clutch operating member 11 is guided by a boss portion 50 (see Figure 3) provided on the first side cover 6a.

[0045] As shown in Figure 5, the clutch operating member 11 has a lever body 51 and a recess 52. The lever body 51 is the part operated by the angler. The recess 52 is provided in the lever body 51. In detail, the recess 52 is provided on the side of the lever body 51 on the first side cover 6a side. The recess 52 extends in the direction in which the lever body 51 swings. For example, the recess 52 is a long groove curved in the direction of swinging.

[0046] As shown in Figure 3, the boss portion 50 is provided on the first side cover 6a between the first side plate 9a and the first side cover 6a. The boss portion 50 is formed integrally with the first side cover 6a. The boss portion 50 is formed in a cylindrical shape so as to protrude from the first side cover 6a.

[0047] As shown in Figures 3 and 6, the tip 50a of the boss portion 50 is inserted through the hole 9a3 of the first side plate 9a. The tip 50a of the boss portion 50 protrudes from the inner surface 9a1 of the first side plate 9a. As shown in Figure 5, the tip 50a of the boss portion 50 is positioned in the recess 52 of the clutch operating member 11. In this state, when the clutch operating member 11 is operated, the lever body 51 moves in the swinging direction with the tip 50a of the boss portion 50 positioned in the recess 52.

[0048] In the double-bearing reel 1 having the above configuration, the clutch cam 43 rotates when the clutch operating member 11 is operated, and the clutch cam 43 presses against the clutch yoke 41. As a result, the clutch yoke 41 moves axially away from the spool 7. This switches the clutch mechanism 25 from the clutch-on state to the clutch-off state.

[0049] On the other hand, when the clutch return mechanism (not shown) is activated by operating the handle 4, the clutch cam 43 rotates in the opposite direction to the rotation direction described above. As a result, the clutch yoke 41 is biased by the coil spring 44 and moves axially toward the spool 7. This switches the clutch mechanism 25 from the clutch-off state to the clutch-on state.

[0050] The double-bearing reel 1 described above has the following features. In the double-bearing reel 1, a boss portion 50 is provided on the first side cover 6a, and the tip portion 50a of the boss portion 50 guides the oscillation of the clutch operating member 11. In this configuration, since the boss portion 50 is not directly provided on the first side plate 9a, the precision of the frame 5 can be improved compared to the conventional configuration.

[0051] In the double-bearing reel 1, the boss portion 50 is integrally formed with the first side cover 6a, so the rigidity of the boss portion 50 can be ensured. In the double-bearing reel 1, the tip portion 50a of the boss portion 50 is positioned in the recess 52 of the lever body 51, so the boss portion 50 can stably swing the lever body 51.

[0052] (modified version) (A) The boss portion 150 in the above embodiment may be formed separately from the first side cover 6a, as shown in Figure 7. In this case, a mounting hole 6a1 is provided on the inner surface of the first side cover 6a. The boss portion 150 is fitted into the mounting hole 6a1. In this state, the boss portion 150 may be fixed to the mounting hole 6a1 by a fixing means such as an adhesive. In this configuration, since the boss portion 150 is formed separately from the first side cover 6a, the ease of assembly of the boss portion 150 can be improved.

[0053] (B) The boss portions 50, 150 in the above embodiment and the above modified example (A) may be a bottomed cylindrical boss portion 250, as shown in Figure 8. In this case, a reinforcing member 55 is arranged on the inner circumference of the boss portion 250. The reinforcing member 55 is, for example, a metal shaft-shaped member. It is preferable that the reinforcing member 55 is press-fitted into the inner surface of the boss portion 250. The reinforcing member 55 may be attached to the inner surface of the boss portion 250 by a fixing means such as an adhesive. In this configuration, since the reinforcing member 55 is arranged on the inner circumference of the boss portion 250, the rigidity and strength of the boss portion 250 can be improved.

[0054] <Other Embodiments> 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.

[0055] (a) In the above embodiment, an example was shown in which the pinion gear 23 is moved in the axial direction using a clutch cam 43 and a clutch yoke 41. Alternatively, the pinion gear 23 may be moved in the axial direction using a mechanism other than the clutch cam 43 and clutch yoke 41. [Explanation of symbols]
