Description

  The present invention relates to a dual bearing reel.

  Dual bearing reels generally include a casting control mechanism. The casting control mechanism is a mechanism that brakes the rotation of the spool shaft by applying a frictional force to the spool shaft. As a result, the rotational speed of the spool shaft at the time of thread feeding is suppressed, and backlash is prevented. Also, when dropping a device in boat fishing or the like, a casting control mechanism is also used to adjust the falling speed of the device in the sea. In the dual-bearing reel described in Patent Literature 1, an operation lever is swingably attached to the reel body in order to facilitate operation of the casting control mechanism. By swinging the operation lever, the braking force on the spool shaft can be adjusted, and the falling speed of the in-process can be adjusted.

JP-A-9-275861

When the casting control mechanism as described above is adjusted to an appropriate braking force using the operation lever, the operation lever may be extended in a direction that is difficult for the angler to operate. For example, when the operation lever extends in the direction toward the fishing rod mounting side, a problem arises that it is difficult for the angler to operate. Further, there is a problem that the fishing line is hooked on the operation lever and becomes entangled.

  An object of the present invention is to provide a dual-bearing reel having an operation lever capable of improving the operability of the operation lever and reducing the occurrence of thread entanglement.

  A dual bearing reel according to a first aspect of the present invention includes a reel body, a spool, a spool shaft, a one-way clutch, and an operation lever. The spool is rotatable with respect to the reel body. The spool shaft rotates integrally with the spool. The one-way clutch has an outer ring and a rolling element. The outer race is rotatable with respect to the reel body. The rolling element transmits the rotation of the spool shaft in the line payout direction to the outer race. The one-way clutch is attached to a spool shaft. The operation lever is attached to the reel body. The operation lever extends in the radial direction and is flat. The operation lever is configured to adjust a braking force for braking the rotation of the outer ring.

  According to this configuration, when the spool shaft rotates in the line payout direction, the rotation of the spool shaft is transmitted to the outer ring via the rolling elements. That is, the spool shaft and the outer ring rotate in conjunction with each other. Since the outer ring is braked by the operation lever, the spool shaft is also braked. As a result, the rotation speed of the spool shaft at the time of thread feeding is suppressed, and backlash is prevented. On the other hand, when the spool shaft rotates in the line winding direction, the rotation of the spool shaft is not transmitted to the outer race. That is, since the spool shaft and the outer ring do not rotate in conjunction with each other, the spool shaft is not braked. Therefore, it is possible to suppress the rotation resistance from being generated on the spool shaft during the winding of the yarn, and the spool shaft can rotate smoothly.

  The operation lever for adjusting the braking force on the outer wheel extends in the radial direction. For this reason, it is possible to operate the operation lever while performing palming. Since the operation lever has a flat shape, the operability of the operation lever is improved, and the fishing line is hardly entangled with the operation lever.

  Preferably, the operation lever has a first extending portion, a second extending portion, and a connecting portion. The first and second extending portions extend in the radial direction. Further, the first and second extending portions are arranged at an interval from each other in the width direction. The connecting portion extends in the width direction so as to connect the respective distal end portions of the first and second extending portions.

  A dual bearing reel according to a second aspect of the present invention includes a reel body, a spool, a spool shaft, a one-way clutch, and an operation lever. The spool is rotatable with respect to the reel body. The spool shaft rotates integrally with the spool. The one-way clutch has an outer ring and a rolling element. The outer race is rotatable with respect to the reel body. The rolling element transmits the rotation of the spool shaft in the line payout direction to the outer race. The one-way clutch is attached to a spool shaft. The operation lever is attached to the reel body. The operation lever is configured to adjust a braking force for braking the rotation of the outer ring. The operation lever has a first extending portion, a second extending portion, and a connecting portion. The first and second extending portions extend in the radial direction. The first and second extending portions are arranged at an interval from each other in the width direction. The connecting portion extends in the width direction so as to connect the respective distal end portions of the first and second extending portions.

  According to this configuration, for the same reason as described above, the rotational speed of the spool shaft at the time of thread feeding is suppressed, and backlash is prevented. Further, it is possible to suppress the occurrence of rotational resistance on the spool shaft during winding of the yarn, and the spool shaft can rotate smoothly.

  The operation lever for adjusting the braking force on the outer wheel extends in the radial direction. For this reason, it is possible to operate the operation lever while performing palming. Since the operation lever has the first and second extending portions arranged at intervals in the width direction, the operability of the operation lever is improved, and the fishing line is hardly entangled with the operation lever. ing.

  Preferably, a radially outer end of the operation lever is concave toward the reel body. According to this configuration, the operation lever can be operated by putting a finger on the concave portion of the operation lever.

  Preferably, a radially outer edge of the operating lever is recessed radially inward. According to this configuration, the operation lever can be operated by putting a finger on the concave portion of the operation lever.

  Preferably, the corner on the tip side of the operation lever is chamfered. According to this configuration, even if the fishing line is hooked on the operation lever, the fishing line can be smoothly released from the operation lever.

  Preferably, the distal end of the operation lever is disposed on the reel body side with respect to the base end of the operation lever. According to this configuration, even if the fishing line is hooked on the operation lever, the fishing line can be smoothly released from the operation lever.

  Preferably, the operation lever has an opening. According to this configuration, the operation lever can be reduced in weight.

  The operation lever has a concave portion that is concave toward the reel body. According to this configuration, the operation lever can be operated by touching the concave portion with a finger.

  Preferably, the operation lever has a smaller width at the radially outer end than at the radially inner end. According to this configuration, even if the fishing line is hooked on the operation lever, the fishing line can be smoothly released from the operation lever.

  Preferably, the operation lever has a cylindrical portion and a lever portion. The cylindrical portion is screwed to the reel body and is movable in the axial direction by rotation. The lever portion extends radially from the cylindrical portion.

  Preferably, one end in the width direction of the lever portion extends from a contact point with the cylindrical portion. According to this configuration, there is no step between the cylindrical portion and the lever portion, and the fishing line is less likely to be caught on the lever portion.

  Preferably, the lever portion has a width that is the same as the diameter of the cylindrical portion.

  Preferably, the operation lever is swingably attached to the reel body. Then, the braking force is adjusted by swinging the operation lever.

  Preferably, the operation lever is screwed to the reel body and presses the outer ring in the axial direction.

  According to the present invention, the operability of the operation lever is improved, and the occurrence of thread entanglement is reduced.

Note that the axial direction refers to the direction in which the spool shaft extends. The radial direction refers to the radial direction of a circle centered on the spool shaft, and the circumferential direction refers to the circumferential direction of the circle centered on the spool shaft.
The width direction means the width direction of the operation reel.

[Double bearing reel]
As shown in FIGS. 1 and 2, the dual-bearing reel 100 includes a reel body 2, a spool 3, a spool shaft 4, a one-way clutch 5, and an operation lever 6. The dual-bearing reel 100 further includes a first friction plate 7, an urging member 8, and a handle 9.

[Reel body]
The reel unit 2 includes a first reel unit 21 and a second reel unit 22. The first reel main body 21 and the second reel main body 22 are spaced from each other in the axial direction. The first reel main body 21 and the second reel main body 22 are connected to each other via a plurality of connecting portions 23.

  The first reel body 21 has a first side plate 21a and a first cover 21b. The first reel body 21 has a housing space inside. The rotation transmitting mechanism 11 and the like are housed in the housing space. The second reel body 22 has a second side plate 22a and a second cover 22b. The first side plate 21a and the second side plate 22a are connected to each other via a connecting portion 23. The first side plate 21a, the second side plate 22a, and the connecting portion 23 are integrally formed, and constitute a frame of the reel body 2.

  As shown in FIG. 3, the first reel body 21 further has a protrusion 24. The protrusion 24 has a cylindrical shape and protrudes outward in the axial direction. Specifically, the protrusion 24 protrudes axially outward from the first cover 21b. The operation lever 6 is attached to the protrusion 24. Specifically, a screw portion is formed on the outer peripheral surface of the protruding portion 24. Then, the operation lever 6 is screwed into the protrusion 24. The protruding portion 24 communicates the accommodation space of the first reel body 21 with the outside. One end of the spool shaft 4 is rotatably supported in the protrusion 24.

[spool]
As shown in FIG. 2, the spool 3 is disposed between the first reel body 21 and the second reel body 22. Specifically, the spool 3 has a substantially cylindrical shape and extends in the axial direction. The spool 3 is rotatable with respect to the reel body 2. The spool 3 is rotatably supported on the reel body 2 via a spool shaft 4.

[Spool axis]
The spool shaft 4 rotates integrally with the spool 3. The spool shaft 4 is rotatably supported by the first reel body 21 and the second reel body 22. The spool shaft 4 is rotatably supported by the first reel body 21 and the second reel body 22 via the first and second bearing members 12a and 12b.

[One-way clutch]
As shown in FIG. 4, the one-way clutch 5 is attached to the spool shaft 4. The one-way clutch 5 has an outer ring 51 and a plurality of rolling elements 52. The outer race 51 is rotatable with respect to the reel body 2. Specifically, the outer ring 51 is rotatable with respect to the protrusion 24. The outer ring 51 is arranged with a gap from the inner peripheral surface of the protrusion 24.

  The outer ring 51 is sandwiched between the first friction plate 7 and the second friction plate 13 in the axial direction. That is, the rotation of the outer ring 51 is braked by the first and second friction plates 7 and 13.

  The rolling element 52 is disposed between the spool shaft 4 and the outer ring 51. The rolling elements 52 transmit the rotation of the spool shaft 4 in the line payout direction to the outer race 51. On the other hand, the rolling elements 52 do not transmit the rotation of the spool shaft 4 in the line winding direction to the outer race 51.

[Operation lever]
As shown in FIG. 3, the operation lever 6 is attached to the reel body 2. The operation lever 6 has a flat shape and extends in the radial direction. Both corners on the distal end side of the operation lever 6 are chamfered. Both corners on the distal end side of the operation lever 6 may be R-chamfered or C-chamfered.

  The operation lever 6 is screwed into the protrusion 24 of the reel body 2. For this reason, the operation lever 6 can swing with respect to the reel body 2. When the operation lever 6 swings, the operation lever 6 moves in the axial direction.

  The operation lever 6 can adjust a braking force for braking the rotation of the outer ring 51. Specifically, by swinging the operation lever 6 and moving it in the axial direction, the force for pressing the outer wheel 51 can be adjusted, and thus the braking force on the outer wheel 51 can be adjusted.

  As shown in FIG. 5, the operation lever 6 has a cylindrical portion 61 and a lever portion 62. The length L of the operation lever 6 is, for example, about 20 to 40 mm. The length L of the operation lever 6 is a length from the rotation axis of the spool shaft 4 in the radial direction. The length direction of the operation lever 6 extends substantially parallel to the radial direction, and the width direction of the operation lever 6 is substantially orthogonal to the length direction of the operation lever 6.

  The cylindrical portion 61 has a screw portion formed on the inner peripheral surface. The cylindrical portion 61 is screwed into the protrusion 24. Therefore, the cylindrical portion 61 is movable in the axial direction by rotating. The outer diameter of the cylindrical portion 61 is, for example, about 15 to 25 mm.

  The lever portion 62 extends from the cylindrical portion 61 in the radial direction. The width W of the lever portion 62 is, for example, about 15 to 25 mm. In the present embodiment, the width W of the lever portion 62 is substantially the same as the diameter of the cylindrical portion 61. That is, both end edges of the lever portion 62 in the width direction extend radially from the contact point with the cylindrical portion 61. Therefore, no step is formed between the lever portion 62 and the cylindrical portion 61 when viewed in the axial direction.

  The lever portion 62 has a first extending portion 621, a second extending portion 622, and a connecting portion 623. The first extending portion 621 and the second extending portion 622 are arranged at intervals in the width direction. The first extension 621 and the second extension 622 extend in the radial direction.

  The first extending portion 621 and the second extending portion 622 have a shape that follows the shape of the reel body 2. Specifically, as shown in FIG. 6, each of the first extending portion 621 and the second extending portion 622 has a step portion 624 at a radially central portion. For this reason, the leading ends of the first extending portion 621 and the second extending portion 622 are arranged on the reel body 2 side with respect to the base end. Note that the base ends of the first extending portion 621 and the second extending portion 622 are ends on the cylindrical portion side.

  As shown in FIG. 5, the connecting portion 623 connects the tip of the first extension 621 and the tip of the second extension 622. The connecting portion 623 extends in the width direction. The connecting portion 623 is formed integrally with the first extending portion 621 and the second extending portion 622.

  As shown in FIG. 4, a seal member 63 is disposed between the inner peripheral surface of the cylindrical portion 61 and the outer peripheral surface of the protrusion 24. The sealing member 63 can prevent foreign matter from entering the inside of the reel body 2. The seal member 63 imparts rotational resistance to the operation lever 6 so that the operation lever 6 does not rotate against the intention of the angler.

  The first friction plate 7 is arranged between the outer ring 51 of the one-way clutch 5 and the operation lever 6. The first friction plate 7 is an annular plate and is in contact with the outer ring 51. The first friction plate 7 is in contact with the outer ring 51 but not in contact with the rolling elements 52. The first friction plate 7 is made of, for example, carbon cloth. The operation lever 6 presses the outer ring 51 in the axial direction via the first friction plate 7.

[Biasing member]
The urging member 8 urges the outer ring 51 of the one-way clutch 5 toward the operation lever 6. That is, the urging member 8 urges the outer ring 51 so that the outer ring 51 does not separate from the first friction plate 7. The urging member 8 urges the outer ring 51 via the second friction plate 13. The second friction plate 13 has an annular shape and is in contact with the outer ring 51 of the one-way clutch 5. The second friction plate 13 is not in contact with the rolling element 52.

  The urging member 8 is restricted from moving in the direction away from the one-way clutch 5 in the axial direction. Specifically, the urging member 8 is supported by the first bearing member 12a. The movement of the first bearing member 12a in the direction away from the one-way clutch 5 is restricted by a step portion 241 formed on the inner peripheral surface of the protruding portion 24.

  The biasing member 8 is, for example, a disc spring. The outer peripheral portion of the urging member 8 urges the outer ring 51 of the one-way clutch 5 via the second friction plate 13. The inner peripheral portion of the biasing member 8 is supported by the inner race of the first bearing member 12a.

  In the axial direction, the distance L1 between one end surface 4a of the spool shaft 4 and the bottom surface 61a of the cylindrical portion 61 of the operation lever 6 is determined by the amount of expansion and contraction of the urging member 8 between the uncompressed state and the maximum compressed state. It is larger than L2 (L1> L2). Thereby, even if the urging member 8 is completely compressed, the end surface 4a of the spool shaft 4 does not contact the bottom surface 61a of the cylindrical portion 61.

[handle]
As shown in FIG. 2, the handle 9 is a member for rotating the spool shaft 4 and is rotatably mounted on the first reel body 21. When the handle 9 rotates, the spool shaft 4 is rotated via the rotation transmission mechanism 11.

[Rotation transmission mechanism]
The rotation transmission mechanism 11 is a mechanism that transmits the rotation of the handle 9 to the spool shaft 4. The rotation transmission mechanism 11 has a drive shaft 11a, a drive gear 11b, a pinion gear 11c, and a clutch mechanism 11d. The drive shaft 11a rotates integrally with the handle 9. The drive gear 11b rotates integrally with the drive shaft 11a. The pinion gear 11c meshes with the drive gear 11b. The pinion gear 11c is cylindrical, and the spool shaft 4 passes through the inside of the pinion gear 11c.

  The clutch mechanism 11d transmits the rotation of the pinion gear 11c to the spool shaft 4 or cuts off the rotation. Specifically, the clutch mechanism 11d includes an engagement pin 11e and an engagement recess 11f. The engagement pin 11e penetrates the spool shaft 4 in the radial direction. The engagement recess 11f is a recess formed at one end of the pinion gear 11c. The rotation of the pinion gear 11c is transmitted to the spool shaft 4 by the engagement of the engagement pin 11e with the engagement recess 11f. On the other hand, when the engagement between the engagement pin 11e and the engagement recess 11f is released by moving the pinion gear 11c away from the engagement pin 11e, the rotation of the pinion gear 11c is not transmitted to the spool shaft 4.

[motion]
Next, the operation of the dual bearing reel 100 will be described. At the time of casting the fishing line from the spool 3, the spool shaft 4 rotates in the line feeding direction. The rotation of the spool shaft 4 in the line let-out direction is transmitted to the outer race 51 via the rolling element 52 of the one-way clutch 5, and the outer race 51 rotates. The outer ring 51 is pressed by the operation lever 6 via the first friction plate 7. That is, since the outer wheel 51 is braked by the operation lever 6, the rotation speed of the outer wheel 51 is suppressed. Since the outer race 51 and the spool shaft 4 are interlocked, the rotation speed of the spool shaft 4 at the time of thread feeding is also suppressed, and backlash is prevented.

  Further, when the operation lever 6 is swung, the operation lever 6 moves in the axial direction, so that the pressing force of the operation lever 6 on the outer ring 51 can be adjusted. That is, by swinging the operation lever 6, the braking force on the spool shaft 4 can be adjusted.

  On the other hand, when winding the fishing line, the spool shaft 4 rotates in the line winding direction. The rolling elements 52 do not transmit the rotation of the spool shaft 4 in the line winding direction to the outer race 51. That is, the spool shaft 4 and the outer ring 51 do not interlock, and the braking force by the operation lever 6 does not act on the spool shaft 4. Therefore, at the time of winding the yarn, no rotation resistance is generated on the spool shaft 4 by the operation lever 6, and the spool shaft 4 can rotate smoothly.

[Modification]
As described above, one embodiment of the present invention has been described, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the invention.

  For example, as shown in FIG. 7, the connecting portion 623 of the operation lever 6 may be recessed toward the reel body 2. With such a shape, the thumb fits to the connecting portion 623, and as a result, the operability of the operation lever 6 is improved.

  As shown in FIG. 8, the radial outer edge of the connecting portion 623 of the operation lever 6 may be recessed radially inward.

  In the above embodiment, the lever portion 62 has the first extension portion 621, the second extension portion 622, and the connecting portion 623, but the configuration of the lever portion 62 is not limited to this. For example, as shown in FIG. 9, the lever portion 62 may be composed of a single flat plate member. In this case, at least one opening 64 may be formed at the center of the lever 62 as shown in FIG. Further, the lever portion 62 may have a concave portion that is recessed toward the reel body 2 instead of the opening portion 64.

  Further, as shown in FIG. 11, the lever portion 62 may have a shape in which a radially outer end is smaller in width than a radially inner end. Specifically, the lever portion 62 may have a shape that tapers in the width direction.

  In addition, as shown in FIG. 12, the one-way clutch 5 may further include an inner ring 53. The inner ring 53 is attached to the spool shaft 4. The rolling elements 52 are arranged between the outer ring 51 and the inner ring 53.

  In the above embodiment, the biasing member 8 is supported in the axial direction by the first bearing member 12a, but is not particularly limited to this. For example, the biasing member 8 may be supported by a step formed on the inner peripheral surface of the protrusion 24.

  In the above embodiment, the one-way clutch 5 is disposed in the first reel body 21, but the one-way clutch 5 may be disposed in the second reel body 22. In this case, the operation lever 6 is also swingably attached to the second reel body 22. The operation lever 6 may be arranged in the second reel body 22. In this case, a part of the operation lever 6 is exposed from the outer peripheral surface of the second reel body 22.
