Description

Torque limiting device for fishing reel and fishing reel

The present invention relates to a torque limiting device for a fishing reel and the fishing reel.

A known fishing reel is known to have a torque limiting device that limits the torque between a rotating shaft member of the fishing reel and a rotating member supported by the shaft member. For example, the fishing reel of Patent Document 1 has a torque limiting device that limits the torque between a handle shaft and a gear supported by the handle shaft. The torque limiting device has: a pin member and a push member. The pin member and the push member are arranged in a through hole formed in the handle shaft.

[The problem the invention is trying to solve]

As is known, the diameter of the through hole in which the pin member and the push member are arranged is smaller than the length of the driven gear in the axial direction of the handlebar shaft. Therefore, for example, the outer diameter of the push member cannot be greater than the length of the driven gear in the axial direction. That is, since the design freedom of the push member is low, it is difficult to improve the durability of the torque limiting device.

The subject of the present invention is to improve the durability of a torque limiting device for a fishing reel and a fishing reel. [Technical means for solving the problem]

The torque limiting device of the fishing reel of the present invention is used to limit the torque between the rotating shaft member of the fishing reel and the rotating member supported by the shaft member. The torque limiting device is provided with: a housing portion, a locking portion, at least one pin member, and at least one pushing member. The housing portion is provided on the shaft member and is open in the radial direction of the shaft member. The locking portion is formed on the inner circumferential surface of the rotating member. At least one pin member is arranged in the housing portion so as to be able to move forward and backward toward the rotating member and can be engaged with the locking portion. At least one pushing member is arranged in the housing portion to push the pin member toward the rotating member. The length of the housing portion in the axial direction of the shaft member is greater than the length of the rotating member in the axial direction.

In the torque limiting device of the fishing reel, since the length of the receiving portion in the axial direction of the shaft member is greater than the length of the rotating member, the design freedom of the pushing member arranged in the receiving portion can be increased. As a result, since, for example, the outer diameter of the pushing member can be greater than the length of the rotating member in the axial direction, the durability of the pushing member can be improved. As a result, the durability of the torque limiting device can be improved.

The pushing member may be a coil spring. The outer diameter of the pushing member may be greater than the length of the rotating member in the axial direction. In this case, since the outer diameter of the coil spring is greater than the length of the rotating member in the axial direction and the wire diameter of the coil spring can be larger than the conventional one, the durability of the coil spring can be improved. As a result, the durability of the torque limiting device can be improved.

The shaft member may have a shank portion that abuts against the rotating member in the axial direction. The receiving portion may be formed by cutting off a portion of the shank portion. In this case, since the receiving portion is formed by cutting off a portion of the shank portion, even if the length of the receiving portion in the axial direction is increased, the shaft member can be prevented from being enlarged in the axial direction.

The engaging portion may have an inclined surface that gradually approaches the axis of the shaft member toward the hub. In this case, when the pin member is engaged with the engaging portion, the inclined surface of the engaging portion generates a force that pushes the rotating member toward the hub, so the rotating member is not easy to move.

Another fishing reel of the present invention comprises: a reel body, a shaft member rotatably supported by the reel body, a rotating member supported by the shaft member, and the above-mentioned torque limiting device capable of limiting the torque between the shaft member and the rotating member.

In this fishing reel, since the length of the housing portion in the axial direction of the shaft member is greater than the length of the rotating member, the design freedom of the push member disposed in the housing portion can be improved. As a result, since, for example, the outer diameter of the push member can be greater than the length of the rotating member in the axial direction, the durability of the push member can be improved. As a result, in the fishing reel, the durability of the torque limiting device can be improved. [Effect of the invention]

According to the present invention, the durability of the torque limiting device of a fishing reel and the fishing reel can be improved.

The double-bearing reel 100 used in one embodiment of the present invention is as shown in FIGS. 1 to 3, and comprises: a reel body 2, a reel 3, an operating rod 4, and a reel drive mechanism 13 (see FIG. 3). The double-bearing reel 100 is an electric reel that drives the reel 3 to rotate by the motor 12 using the power supplied from an external power source. The double-bearing reel 100 is an example of a fishing reel. In the following description, the axial direction means the direction in which the reel shaft 10 and the drive shaft 30 described later extend.

The reel body 2 includes a frame 7, a first side cover 8a, and a second side cover 8b. The frame 7 includes a first side plate 7a, a second side plate 7b, a plurality of connection parts 7c, and a mechanism mounting plate 9.

The first side plate 7a is arranged on the right side facing the front (the direction in which the fishing line is discharged) of the frame 7. The second side plate 7b is arranged on the left side of the frame 7 with a gap in the axial direction from the first side plate 7a. The plurality of connecting parts 7c extend in the axial direction to connect the first side plate 7a and the second side plate 7b. The mechanism mounting plate 9 is arranged between the first side plate 7a and the first side cover 8a. The mechanism mounting plate 9 is arranged between the first side plate 7a and the first side cover 8a, and various mechanisms are installed in the mechanism mounting plate 9.

The first side cover 8a covers the right side of the first side plate 7a of the frame 7. The second side cover 8b covers the left side of the second side plate 7b of the frame 7.

As shown in FIG. 2, the reel 3 is rotatable with respect to the reel body 2 and is arranged between the first side plate 7a and the second side plate 7b. The reel 3 is supported by the reel shaft 10 extending in the axial direction inside the reel body 2. The reel 3 is rotatably mounted on the reel shaft 10 as a whole. The reel shaft 10 is rotatably supported by the reel body 2 via a pair of bearings 11a and 11b arranged on the reel body 2. The reel shaft 10 of this embodiment extends in the left-right direction.

The operating lever 4 is rotatable with respect to the reel body 2. The operating lever 4 is provided on the first side cover 8a side of the reel body 2.

The reel drive mechanism 13 transmits the rotation of the operating rod 4 and the motor 12 to the reel 3. As shown in FIG. 3 , the reel drive mechanism 13 includes a first rotation transmission mechanism 14 and a second rotation transmission mechanism 15.

The first rotation transmission mechanism 14 decelerates the rotation of the motor 12 and transmits it to the reel 3. Specifically, the first rotation transmission mechanism 14 includes a planetary gear mechanism (not shown) connected to the output shaft of the motor 12, a first gear member 60, a second gear member 61, and a pinion 32.

The rotation of the motor 12 is transmitted to the first gear member 60 through the planetary gear mechanism. The second gear member 61 is engaged with the first gear member 60. The second gear member 61 is an intermediate gear for transmitting the rotation of the first gear member 60 to the small gear 32, and is engaged with the small gear 32.

The pinion gear 32 is rotatable around the axis of the reel shaft 10, and the reel shaft 10 passes through the inner periphery. The pinion gear 32 is provided on the reel body 2 so as to be movable in the axial direction between a connection position where the pinion gear 32 is integrally rotatably connected to the reel shaft 10 and a release position where the connection with the reel shaft 10 is released. The pinion gear 32 is engaged with the clutch yoke 41 described later, and moves in the axial direction together with the clutch yoke 41. The pinion gear 32 has an annular recess 32a with which the clutch yoke 41 is engaged.

The second rotation transmission mechanism 15 transmits the rotation of the operating rod 4 to the reel 3 via the first rotation transmission mechanism 14. The second rotation transmission mechanism 15 includes a drive shaft 30, a drive gear 31, and a third gear member 62.

The drive shaft 30 is an example of a shaft member. The operating lever 4 is connected to the drive shaft 30 so as to be rotatable as an integral unit. The drive shaft 30 is rotatably supported by the reel body 2. The drive shaft 30 extends in the left-right direction. As shown in FIG. 5 , the drive shaft 30 has: a mounting portion 30a, and a butt portion 30b. The mounting portion 30a is a portion on which a rotating member 52 described later is mounted. The outer peripheral surface of the mounting portion 30a is formed in a cylindrical shape. The butt portion 30b extends further outward in the radial direction of the drive shaft 30 than the mounting portion 30a. The outer diameter of the butt portion 30b is formed to be larger than the outer diameter of the mounting portion 30a. The button portion 30b is disposed adjacent to the mounting portion 30a on the side of the operating rod 4 relative to the mounting portion 30a.

The drive shaft 30 is prohibited from rotating in the opposite direction of the wire winding direction by a roller clutch (not shown) installed on the first side cover 8a. In addition, the drive shaft 30 is also prohibited from rotating in the opposite direction of the wire winding direction by a claw-type one-way clutch composed of a rotating member 52 and a claw member 54 (see FIG. 4 ) that can engage with the rotating member 52.

The driving gear 31 is rotatably mounted on the driving shaft 30. The rotation of the driving shaft 30 is transmitted to the driving gear 31 through a well-known traction mechanism.

The third gear member 62 is engaged with the driving gear 31 and is integrally rotatably connected to the pinion support of the planetary gear mechanism. Thus, the rotation of the third gear member 62 is transmitted to the pinion support 32 via the pinion support, the first gear member 60, and the second gear member 61.

The double bearing reel 100 further includes a clutch mechanism 16 (see FIG. 2 ) and a clutch operating member 17 (see FIG. 3 ). Furthermore, the double bearing reel 100 further includes a clutch control mechanism 20 , a clutch return mechanism 22 , and a limiting member 24 , as shown in FIG. 4 and FIG. 6 .

The clutch mechanism 16 is a mechanism for transmitting and blocking the rotational force of the operating rod 4 to the spool 3. The clutch mechanism 16 has the same structure as the conventional one and is provided between the spool shaft 10 and the small gear 32. As shown in FIG. 2 , the clutch mechanism 16 has an engagement pin 16a and an engagement recess 16b.

When the clutch mechanism 16 is in the transmitting state, that is, when the pinion gear 32 is in the connecting position, the engagement pin 16a is engaged with the engagement recess 16b, so that the rotation of the pinion gear 32 is transmitted to the spool shaft 10. On the other hand, when the clutch mechanism 16 is in the blocking state, that is, when the pinion gear 32 is in the releasing position, the engagement pin 16a is disengaged from the engagement recess 16b, and the rotation of the pinion gear 32 is not transmitted to the spool shaft 10.

The clutch operating member 17 is supported by the reel body 2 so as to be movable in the up-down direction at the rear of the reel body 2. The clutch operating member 17 is movable between a first position indicated by a solid line and a second position indicated by a dotted line in FIG. 3 and is urged toward the first position.

As shown in FIG. 4, the clutch operating member 17 includes a rotating portion 18 and an operating portion 19. The rotating portion 18 is supported on the reel body 2 so as to be rotatable around the axis of the winding shaft 10. The rotating portion 18 includes a ring portion 18a, an insertion portion 18b, a first spring mounting portion 18c, and a connecting portion 18d. The ring portion 18a is supported movably on the outer peripheral surface of the first supporting portion 9a provided on the mechanism mounting plate 9. The insertion portion 18b penetrates the operating portion 19 in the axial direction and is connected to the operating portion 19 so as to be integrally movable.

The first spring mounting portion 18c is formed to extend radially outward from the outer peripheral portion of the ring portion 18a. One end of the first spring member 51 that pushes the clutch operating member 17 toward the first position is hooked on the first spring mounting portion 18c. The first spring member 51 is, for example, a coil spring. The other end of the first spring member 51 is hooked on the outer side surface of the first side cover 8a of the mechanism mounting plate 9.

The connecting portion 18d connects the ring portion 18a and the insertion portion 18b. A support shaft 18e for supporting a clutch claw 44 of the clutch control mechanism 20, which will be described later, is provided in the connecting portion 18d.

The operation portion 19 is a portion for operating the clutch operation member 17 by pushing it by hand. The operation portion 19 is arranged substantially parallel to the reel shaft 10. The operation portion 19 is movable along the first side plate 7a and the second side plate 7b via the first contact member 43a and the second contact member 43b.

The clutch control mechanism 20 alternately switches the clutch mechanism 16 between the transmission state and the blocking state whenever the clutch operating member 17 moves from the first position to the second position. The structure of the clutch control mechanism 20 is the same as that of the prior art, so it is briefly described here.

The clutch control mechanism 20 includes a clutch cam 40 , a clutch yoke 41 , and a clutch claw 44 .

The clutch cam 40 rotates in only one direction whenever the clutch operating member 17 moves from the first position to the second position. Specifically, the clutch cam 40 rotates in only a predetermined rotation phase RP in the first direction R1 shown in FIG. 6 whenever the clutch operating member 17 moves from the first position to the second position. The clutch cam 40 is rotatably mounted on the first supporting portion 9a of the mechanism mounting plate 9.

As shown in FIG. 6 , the clutch cam 40 has a plurality of ratchet teeth 40a and a plurality of cam portions 40b. The plurality of ratchet teeth 40a are arranged at intervals in the circumferential direction on the outer peripheral surface of the clutch cam 40. The prescribed rotation phase RP is determined by the number of ratchet teeth 40a. In the present embodiment, the number of ratchet teeth 40a is 12, and the prescribed rotation phase RP is 30 degrees.

The ratchet teeth 40a include first ratchet teeth 40c and second ratchet teeth 40d. The first ratchet teeth 40c and the second ratchet teeth 40d are alternately arranged at intervals in the circumferential direction.

The cam portions 40b are provided at intervals in the circumferential direction at a phase PS associated with a predetermined rotation phase RP. The cam portions 40b move the clutch yoke 41 in the axial direction whenever the clutch operating member 17 moves from the first position to the second position.

The clutch yoke 41 is provided to move the pinion gear 32 to the connection position and the release position. As shown in FIG. 4 , the clutch yoke 41 is supported movably in the axial direction by the guide member 49 fixed to the first support portion 9a of the mechanism mounting plate 9. The clutch yoke 41 is urged in the axial direction toward the clutch cam 40 by the two second spring members 42 mounted on the guide member 49. The clutch yoke 41 has an engaging portion 41a that engages with the annular recess 32a of the pinion gear 32.

The clutch pawl 44 is supported on the support shaft 18e of the rotating part 18 so as to be swingable. The clutch pawl 44 rotates the clutch cam 40 in the first direction R1 by a predetermined rotation phase RP as the clutch operating member 17 moves from the first position to the second position. Specifically, the clutch pawl 44 engages with either the first ratchet tooth 40c or the second ratchet tooth 40d of the ratchet tooth 40a to push the clutch cam 40 in the first direction R1. The clutch pawl 44 is urged toward the ratchet tooth 40a by the third spring member 48 supported on the support shaft 18e of the rotating part 18.

The clutch return mechanism 22 is a mechanism for returning the clutch mechanism 16 to the transmission state by the rotation of the operating rod 4 when the clutch mechanism 16 is in the blocking state. The clutch return mechanism 22 has a rotating member 52. The rotating member 52 is supported by the drive shaft 30 and rotates in response to the rotation of the operating rod 4. The rotating member 52 is mounted on the mounting portion 30a. The rotating member 52 abuts against the collar portion 30b in the axial direction. The axial movement of the rotating member 52 is restricted by the collar portion 30b.

The rotating member 52 has a plurality of protrusions 52a and a connection hole 52b. The protrusions 52a are provided at intervals in the circumferential direction. When the clutch mechanism 16 is in the blocking state, the protrusions 52a engage with the first ratchet tooth 40c of the clutch cam 40 by the rotation of the operating lever 4, and the clutch cam 40 rotates in the first direction R1.

The protrusion 52a is not engaged with the second ratchet tooth 40d of the clutch cam 40. Specifically, the thickness of the second ratchet tooth 40d in the radial direction is formed thinner than the first ratchet tooth 40c. Furthermore, when the clutch mechanism 16 is in the transmission state, the protrusion 52a is arranged at a position close to the second ratchet tooth 40d. Therefore, even if the operating lever 4 rotates, the clutch cam 40 does not rotate in the first direction R1 due to the protrusion 52a.

The connection hole 52b is circular except for an engaging portion 72 described later, and the drive shaft 30 penetrates in the axial direction.

The limiting member 24 limits the operation of the clutch return mechanism 22 when the clutch mechanism 16 is switched from the transmission state to the blocking state by the movement of the clutch operating member 17.

Specifically, when the clutch mechanism 16 is in the transmission state, if the clutch operating member 17 is moved from the first position to the second position, the clutch mechanism 16 is switched from the transmission state to the blocking state by the rotation of the clutch cam 40. The limiting member 24 limits the operation of the clutch return mechanism 22 during at least a portion of the period from when the clutch operating member 17 returns to the second position when the clutch mechanism 16 is switched from the transmission state to the blocking state. At least a portion of the period includes when the clutch operating member 17 is in the second position.

As shown in FIG. 4 , the limiting member 24 is provided on the rotating portion 18 of the clutch operating member 17. Specifically, the limiting member 24 extends in a plate shape from the ring portion 18a of the rotating portion 18 in the axial direction. The limiting member 24 is provided integrally on the rotating portion 18. The limiting member 24 is formed by, for example, bending a portion of the rotating portion 18.

The limiting member 24 limits the interference between the first ratchet tooth 40c of the clutch cam 40 and the protrusion 52a of the rotating member 52 when the clutch mechanism 16 is switched from the transmission state to the blocking state by the movement of the clutch operating member 17. Specifically, the limiting member 24 rotates from the standby position indicated by the solid line in FIG. 6 to the limiting position indicated by the dotted line by rotating the rotating portion 18 accompanying the movement of the clutch operating member 17 from the first position to the second position. Thus, the rotation of the rotating member 52 in the wire winding direction WD is limited by the limiting member 24, and the operation of the clutch return mechanism 22 caused by the rotation of the operating rod 4 is prevented.

As shown in Fig. 6 and Fig. 7, the double bearing reel 100 further includes a torque limiting device 70. The torque limiting device 70 limits the torque transmitted between the drive shaft 30 and the rotating member 52. The torque limiting device 70 is provided to prevent damage to the limiting member 24 and the protrusion 52a when a large load is applied to the limiting member 24.

The torque limiting device 70 includes a receiving portion 71 , an engaging portion 72 , a pair of pin members 73 , and a pressing member 74 .

The receiving portion 71 is provided on the drive shaft 30. The receiving portion 71 is formed on the mounting portion 30a. The receiving portion 71 is opened in the radial direction of the drive shaft 30. In the present embodiment, the receiving portion 71 is composed of a through hole formed by penetrating the mounting portion 30a in the radial direction. The receiving portion 71 is formed by cutting off a portion of the butt portion 30b as shown in FIG. 5 and FIG. 8. A portion of the receiving portion 71 overlaps with the butt portion 30b in the radial direction.

As shown in FIG. 8 , the length L1 of the receiving portion 71 in the axial direction is greater than the length L2 of the rotating member 52 in the axial direction. The length L1 of the receiving portion 71 is preferably longer than the length L2 of the rotating member 52. FIG. 8 shows an embodiment in which the length L1 of the receiving portion 71 is longer than the length L2 of the rotating member 52.

The engaging portion 72 is formed on the inner circumferential surface of the rotating member 52. The engaging portion 72 is formed on the inner circumferential surface of the rotating member 52 so as to be recessed outward in the radial direction. The engaging portion 72 is formed in the connecting hole 52b. In the present embodiment, four engaging portions 72 are provided at intervals in the circumferential direction and are recessed from the mounting portion 30a side toward the connecting hole 52b.

The engaging portion 72 includes a stopper surface 72a, a first inclined surface 72b, and a second inclined surface 72c. The stopper surface 72a is formed along the front end of a pair of pin members 73. The first inclined surface 72b is a structure for pushing the rotating member 52 toward the wire winding direction WD. The inner diameter of the first inclined surface 72b is inclined in a straight line when viewed from the axial direction of the drive shaft 30, and is formed to gradually increase as it advances toward the wire winding direction WD.

The second inclined surface 72c is an example of an inclined surface. As shown in FIG. 8, the second inclined surface 72c is inclined toward the hub 30b and gradually approaches the shaft core C (see FIG. 7) of the drive shaft 30. In addition, the shaft core C of the drive shaft 30 extends in a direction perpendicular to the paper surface of FIG. 7. The second inclined surface 72c is formed across the stop surface 72a and the first inclined surface 72b. In addition, the second inclined surface 72c may be formed only on the stop surface 72a.

A pair of pin members 73 are arranged in the housing portion 71 so as to be able to move forward and backward toward the rotating member 52. The movement of the pair of pin members 73 in the radial direction is guided by the inner circumferential surface of the housing portion 71. The length L3 of the pair of pin members 73 in the axial direction is greater than the length L2 of the rotating member 52. The length L3 of the pair of pin members 73 is preferably longer than the length L2 of the rotating member 52. FIG. 8 shows an embodiment in which the length L3 of the pair of pin members 73 is longer than the length L2 of the rotating member 52. The length L3 of the pair of pin members 73 is shorter than the length L1 of the housing portion 71.

A pair of pin members 73 can be engaged with the engaging portion 72. A pair of pin members 73 has a head portion 73a with a spherical front end and a shaft portion 73b with a smaller diameter than the head portion 73a. The rotating member 52 rotates along with the rotation of the drive shaft 30 by pressing the stop surface 72a with the head portion 73a. If a torque greater than the allowable value acts between the drive shaft 30 and the rotating member 52, the head portion 73a will retreat toward the inside of the accommodating portion 71, and the drive shaft 30 will rotate relative to the rotating member 52. That is, if a torque greater than the allowable value acts between the drive shaft 30 and the rotating member 52, only the drive shaft 30 will rotate. When the pair of pin members 73 are engaged with the engagement portion 72, the pair of pin members 73 presses the rotation member 52 toward the hinge portion 30b via the second inclined surface 72c.

The pushing member 74 is arranged in the accommodating portion 71. The pushing member 74 pushes a pair of pin members 73 toward the rotating member 52. The pushing member 74 is, for example, a coil spring, and is installed on the shaft portion 73b of the pair of pin members 73 in a compressed state. The outer diameter D1 of the pushing member 74 is greater than the length L2 of the rotating member 52 in the axial direction. As shown in FIG. 8, the outer diameter D1 of the pushing member 74 is preferably longer than the length L2 of the rotating member 52. FIG. 8 shows an embodiment in which the outer diameter D1 of the pushing member 74 is longer than the length L2 of the rotating member 52. The outer diameter D1 of the pushing member 74 is smaller than the length L1 of the accommodating portion 71. The inner diameter of the pushing member 74 is larger than the outer diameter of the shaft portion 73b and smaller than the outer diameter of the head portion 73a.

In the torque limiting device 70 of the above structure, since the length L1 of the housing portion 71 in the axial direction is greater than the length L2 of the rotating member 52, the degree of freedom in design of the pressing member 74 disposed in the housing portion 71 can be increased. As a result, for example, since the outer diameter of the pressing member 74 (here, the outer diameter D1 of the coil spring) can be greater than the length L2 of the rotating member 52, the durability of the pressing member 74 can be improved. As a result, the durability of the torque limiting device 70 can be improved. In addition, since the length L3 of the pair of pin members 73 in the axial direction can also be greater than the length L2 of the rotating member 52, the durability of the torque limiting device 70 can be further improved.

<Other implementations> Although one implementation of the present invention has been described above, the present invention is not limited to the above-mentioned implementation, and various modifications can be made without departing from the essential scope of the invention. In particular, the multiple implementations and variations described in this specification can be arbitrarily combined as needed.

(a) In the above-mentioned embodiment, although the fishing reel is an electric reel in which the spool 3 is driven by the motor 12, the present invention can also be applied to a double-bearing reel for manual winding.

(b) In the above-mentioned embodiment, the restricting member 24 is integrally provided on the rotating portion 18, but it is not necessarily required to be integrally provided on the rotating portion 18. Furthermore, the restricting member 24 is not necessarily required to be provided on the rotating portion 18.

(c) In the above-mentioned embodiment, the rotating member 52 has a structure that combines the one-way clutch and the clutch return mechanism 22, but the rotating member 52 does not necessarily have a structure that combines the one-way clutch and the clutch return mechanism 22. The ratchet member that can be engaged with the pawl member 54 and can rotate integrally with the drive shaft 30 may be provided separately from the rotating member 52.

(d) In the above-mentioned embodiment, the torque limiting device 70 is a structure that limits the torque transmitted between the drive shaft 30 and the rotating member 52. However, the torque limiting device 70 may limit the torque between the snail shaft of the uniform winding mechanism that uniformly winds the fishing line onto the reel 3 and the driven gear supported by the snail shaft. Furthermore, the torque limiting device 70 may limit the torque between the drive shaft 30 and other rotating members supported by the drive shaft 30. For example, the torque between the rotating member that transmits rotation to the driven gear and the drive shaft 30 may be limited. Furthermore, it is also possible to limit the moment between the winding shaft 10 and the rotating member supported by the winding shaft 10.

(e) The torque limiting device 70 only needs to have at least one pin member 73. The torque limiting device 70 only needs to have at least one engaging portion 72. The receiving portion 71 does not necessarily need to penetrate the mounting portion 30a in the radial direction. Furthermore, the outer peripheral surface of the mounting portion 30a on which the rotating member 52 is mounted does not necessarily need to be cylindrical.
