[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more specifically, by operating an operating member provided on one side of a reel body, drag force (braking force) is applied to a spool rotatably mounted between side plates of the reel body.

2. Description of the Related Art Recently, as disclosed in Japanese Utility Model Publication No. 1-42463 or Japanese Utility Model Publication No. 4-25977, a spool is rotatably supported between side plates of a reel body and is displaced to a side plate of the reel body. By operating the lever-shaped operation member (hereinafter referred to as "drag lever") that is possible,
There is known a fishing reel called a lever drag reel equipped with a drag device that applies a drag force to the spool.

According to this fishing reel, when the fishing line is subjected to a large pulling force due to a strong pull of the fish or a sudden reversal, the cutting of the fishing line is prevented by the original function of the drag device. Of course, by switching the drag device from the non-operating state to the operating state by operating the drag lever,
The drag device functions like a conventional clutch mechanism, and the driving force by the winding operation of the handle is transmitted to the spool via the drag device, and the spool rotates in the winding direction.

This structure is widely used mainly for medium to large-sized fishing reels because a large braking force is applied when the spool is rotated. by the way,
Conventionally, many fishing reels such as a dual bearing reel and an electric reel are equipped with a reverse rotation preventing device for preventing reverse rotation of a rotating shaft that rotates in conjunction with a winding operation of a handle or a spool motor in a reel body. However, also in the fishing reels of the above-mentioned respective publications referred to as lever dragrilles, the reverse rotation preventing device is similarly mounted.

In the fishing reel disclosed in Japanese Utility Model Publication No. 1-42463, the pinion gear meshing with the drive gear of the handle shaft cannot be relatively moved to the handle side of the spool shaft that rotatably supports the spool between the side plates. Attached to
Reversing the handle shaft when feeding the fishing line, by integrally attaching the drag disk of the drag device equipped with the ratchet part to the side opposite to the handle of the spool shaft, and by attaching the locking claw that locks to the ratchet part to the side plate. We are trying to prevent it.

Further, in the fishing reel disclosed in Japanese Utility Model Publication No. 4-25977, a ratchet is integrally attached to a drive gear attached to a handle shaft, and a locking claw for locking the ratchet portion is provided on a side plate. It is also attached to the wheel to prevent the handle shaft from rotating backwards.

[Problems to be Solved by the Invention] However, the actual fairness 1
The fishing reel disclosed in Japanese Patent Publication No. 424663 has a handle portion of a spool shaft for transmitting a winding driving force of a handle (meshing portion of a drive gear and a pinion gear), and a reverse rotation preventing portion (a drag portion) on a side opposite to a handle. Disk),
Due to the structure in which the action points of force are arranged at both ends of the spool shaft, the spool shaft may be deformed due to the influence of the torsional load applied to the spool shaft, and the spool-free property may be impaired.

Further, in order to reduce the influence of the torsional load, it is necessary to make the spool shaft thicker so as to have strength, but by making the spool shaft thicker, the weight of the entire reel increases. There is. On the other hand, actual fair 4-25977
In the fishing reel disclosed in the publication, when the reverse rotation is stopped when the fishing line is suddenly delivered, the reverse rotation force is transmitted through the pinion gear and the drive gear, so that the gears can be used for a long period of time. There is a risk that the tooth surface of the stencil may be damaged or deformed, and the winding rotation performance may be impaired.

The present invention has been devised in view of the above circumstances, and provides a fishing reel in which a reliable reverse rotation preventing function can be obtained by a reverse rotation preventing device without impairing the spool-free property and the winding rotation performance. The purpose is to

Furthermore, the plurality of planetary gears 53 are supported by the third carrier 61, and the carrier 61 is connected to the rotary drive shaft 37 via a locking pin 63.

Then, the fishing reel 6 according to the present embodiment.
The reference numeral 5 applies a braking force to the spool 9 which is rotated by the feeding of the fishing line on the rotary drive shaft 37 described above.
A drag device 69 is provided which exerts a braking action that permits the rotation of the fishing line in the fishing line payout direction, and uses this braking action to switch the spool 9 between the spool-free state and the fishing line winding state, and is rotationally driven. A drag lever 71 for adjusting the drag force of the drag device 69 is attached to the side plate 7 on the shaft 37.

As shown in FIG. 2, the drag device 69 has a cylindrical friction braking body 73 to which the rotary drive shaft 37 is axially inserted and rotatably attached to the rotary drive shaft 37, and the friction brake body 73. A first washer 75 that meshes with and rotates integrally with the first washer 75, two washers 77 and 78 that are rotationally fixed to the rotary drive shaft 37, and rotates in the front-rear direction with respect to the side plate 7 of the reel unit 1. Of the lever-shaped drag lever 71 that is mounted so as to be movable, a pressing mechanism that moves so as to press the washers 75, 77, 78 when the drag lever 71 is rotated in the front-rear direction, and the washers 75, 77, 78. The washer 75, 7 is provided with a lining material 79 interposed between the braking surfaces.
The 7, 78 and the lining material 79 are accommodated in the concave accommodating portion 81 of the friction braking body 73 and are movable in the axial direction of the rotary drive shaft 37.

The above-mentioned pressing mechanism is provided with the drag lever 7
The first cam member 83, which is engaged with the first rotation stopper, and the second cam member 83, which is engaged with the cam member 83 and moves in the axial direction of the rotary drive shaft 37 by the rotation of the cam member 83 accompanying the operation of the drag lever 71. Cam member 85, a pressing member 87 that is held by the cam member 85 and moves in the axial direction together with the cam member 85, and a pressing body 89 that is rotatably fitted and supported by the rotary drive shaft 37 to press the washer 78. And the pressing member 87
And a pressing body 89, and includes a leaf spring 91 and a bearing 41 which are pressed and moved by the pressing member 87. The cam members 83 and 85 are housed in a support member 93 formed in the side plate 7 of the reel body 1 and having a cylindrical shape in plan view, and supported by the support member 93 so as to be movable in the axial direction of the rotation drive shaft 37. ing.

The rotation of the cam member 85 is restricted by engaging with a detent groove 95 formed in the inner surface of the support member 93 along the axial direction.
Supports the end portion of the rotary drive shaft 37 rotatably as described above, and can move in the axial direction with respect to the rotary drive shaft 37, and the leaf spring 91 is fitted to the outer periphery of the rotary drive shaft 37. Thus, the rotary drive shaft 37 can move in the axial direction.

As shown in FIG. 3, a predetermined gap 97 is formed between the pressing member 87 and the end of the rotary drive shaft 37 to allow the pressing member 87 to move in the axial direction. Also,
Between the friction braking body 73 and the washer 77 and between the washer 77 and the washer 78 on the pressing body 89 side, respectively.
A compression coil spring 99 is wound around the outer circumference of the rotary drive shaft 37, and the compression coil spring 99 urges the friction braking body 73 and the washers 77, 78 in a direction in which they are axially separated from each other.

A retaining plate 101 for preventing the drag lever 71 from falling is screwed to the side plate 7 of the reel unit 1 via a retaining ring 103. The above-mentioned pressing member 87 is engaged with the fine adjustment knob 105, and the operation of the fine adjustment knob 105 causes the pressing member 87 to move in the axial direction. The pinion gear 107 is integrally rotatably fitted on the outer periphery of the small diameter portion of the friction braking body 73, and the drive gear 109 of the manual winding drive mechanism 11 is meshed with the pinion gear 107.

The manual winding drive mechanism 11 includes a handle 13
And a handle shaft 67 to which the handle 13 is attached, and a drive gear 109 fitted in the handle shaft 67 to prevent rotation. When the spool motor 23 drives the spool 9 to be wound up, the handle shaft 67 is prevented from rotating in conjunction with this, and when the spool reversing force is generated by the sudden feeding of the fishing line, the handle shaft 67 is rotated. A reverse rotation preventing device 111 for preventing reverse rotation is provided between the friction braking body 73 and the side plate 7.

As shown in the figure, the reverse rotation preventing device 111 is provided with a plurality of ratchets (reverse rotation preventing portions) 113 provided in the circumferential direction along the outer circumference of the cylindrical friction braking body 73, and is fixed with respect to the ratchet 113. It is composed of a locking claw (locking member) 115 that is constantly engaged by a biasing force, and the locking claw 115 is screwed to the inner periphery of the side plate 7. Then, when the spool 9 is driven to be wound up by the spool motor 23, the ratchet 113 engages with the engaging claw 115 in the engaging direction in the rotating direction, and rotation of the friction braking body 73, that is, rotation of the handle shaft 67 is prevented. It is supposed to be done.

Therefore, the driving force of the spool motor 23 is
It is transmitted only to the spool 9 via the planetary gear transmission mechanism 35. On the other hand, when the spool 9 is rotated in the fishing line winding direction by the handle operation, the locking claw 115 allows the friction braking body 73 to rotate in the rotation direction, and is interlocked with the rotation operation of the handle 13. Steering wheel shaft 67
Can be rotated.

In addition, reference numeral 117 in FIG. 1 denotes a connector for connecting a power supply cord (not shown). Since the present embodiment is configured in this manner, if the fishing reel 65 is connected to an external power source on the ship via a power cord (not shown),
The spool motor 23 can be driven. When the drag lever 71 is operated in the actuating direction, the cam member 83 that is fitted in the drag lever 71 by rotation is rotated, and the cam member 85 moves in the axial direction of the rotary drive shaft 37. As a result,
The bearing 41, the leaf spring 91, and the pressing body 89 are the compression coil spring 9.
The washer 75, 77, 78 is pressed by the pressing body 89 against the spring force of 9 and the washer 75, 77, 78 is slid in the axial direction of the rotary drive shaft 37, and each washer 75, 77, 78 is slid in the axial direction. The braking surfaces are pressed against each other via the lining material 79, and the washer 77 is pressed against the friction braking body 73 with a predetermined pressing force. Then, the pressing force at this time acts on the rotary drive shaft 37 from the washer 77,
The components of the pressing mechanism including the pressing body 89 are the rotary drive shaft 37.
Is frictionally coupled to the spool 9 to generate a predetermined drag force on the spool 9.

The adjustment of the strength of the drag force changes according to the operation amount of the drag lever 71. Then, with the predetermined drag force thus generated, the handle 13
When the winding operation of the drive gear 10
Since the pinion gear 107 is rotated by 9, the friction braking body 73 integrated with the pinion gear 107 is rotated, and the rotation of the friction braking body 73 is transmitted to the rotary drive shaft 37 according to the friction coupling force of the pressing mechanism to rotate the rotation. The carrier 61 connected to the drive shaft 37 rotates counterclockwise.

At this time, the planetary gear 55 rotates counterclockwise and revolves around the sun gear, and rotationally drives the internal gear 47 with the speed increased counterclockwise. As a result, the spool 9 is rotationally driven in the fishing line winding direction. The internal gear 4
The sun gear 43 tries to rotate clockwise by the counterclockwise rotational drive of 7, but the rotational drive is blocked by the one-way clutch 31.

During the winding operation of the handle 13, the drag lever 71 attached to the side plate 7 on the rotary drive shaft 37 does not rotate in association with the handle operation. Further, when the spool motor 23 is driven, the first sun gear 43 is rotationally driven clockwise. As a result, the planetary gear 45 is driven to rotate counterclockwise and revolves clockwise, and the third sun gear 53 rotates clockwise. In this rotation direction, the ratchet 113 and the locking claw 115 are rotated. Since the rotation of the friction braking body 73 is blocked by the locking, the pinion gear 107 does not rotate and the rotation of the handle shaft 67 is blocked. As a result, the rotation drive shaft 37 and the carrier 53 do not rotate, but the sun gear 53 rotates clockwise, so that the planetary gear 55 supported by the carrier 53 does not revolve around the sun gear 53 and is constant. It will rotate counterclockwise at the position.

In this state, the counterclockwise rotational movement of the planetary gear 55 is decelerated and transmitted to the internal gear 47,
As a result, the spool 9 rotates in the fishing line winding direction and the fishing line is wound. As described above, during this winding operation, even if the handle 13 does not rotate in conjunction with the action of the reverse rotation prevention device 111 and a sudden spool reverse rotation force is generated when the fishing line is delivered, the reverse rotation prevention device 111 causes the handlebar 13 to rotate. Reverse 13 is blocked.

On the other hand, if the drag lever 71 is rotationally operated in the non-operating direction, the drag force is gradually weakened, and if the drag lever 71 is sufficiently rotationally operated in the same direction, the spool 9 will be a spool such as a clutch OFF. In the free state, the fishing line can be paid out from the spool 9 by the free fall of the device.

As described above, in this embodiment, the rotary drive shaft 37 connected to the planetary gear transmission mechanism 35 is arranged between the planetary gear transmission mechanism 35 and the manual winding drive mechanism 11.
Then, the washers 75, 77, 7 are attached to the rotary drive shaft 37.
8 is provided with a ratchet 113 on the outer periphery of the friction braking body 73 of the drag device 69 frictionally coupled to the ratchet 113 via the lining material 79, and the locking claw 1 for locking the ratchet 113 is provided.
Since 15 is provided on the side plate 7 side to configure the reverse rotation prevention device 111, even if a sudden spool reverse rotation force is generated at the time of feeding the fishing line, the friction braking body 73 before the force is transmitted to the manual winding drive mechanism 11 is generated. Since the reverse rotation is prevented by the engagement of the ratchet 113 and the engagement claw 115, the reverse rotation force is not transmitted to the meshing portion of the pinion gear 107 and the drive gear 109, and as a result, the tooth surfaces of both gears 107 and 109 are damaged. It is possible to maintain good winding and rotating performance without the occurrence of deformation or deformation.

Further, according to the structure of this embodiment, unlike the above-mentioned Japanese Utility Model Publication No. 1-42463, the spool-free property is not impaired, and a plurality of braking members (washers 75, 77, 78 and The pinion gear 10 is attached to the cylindrical friction braking body 73 in which the lining material 79) is housed.
By integrally providing 7 and the ratchet 113, the braking unit, the power transmission unit, the reverse rotation prevention unit, and the like are integrated, and the reel as a whole can be made compact.

Furthermore, according to the present embodiment, in the manual / electric combined type reel as in the present embodiment, the motor power driving unit, the manual winding driving unit, and the drag device are drive-connected easily and reasonably. It is possible.

[0038]

As described above, according to the first aspect of the present invention, even if a sudden spool reverse force is generated at the time of feeding the fishing line, the drag is transmitted before the force is transmitted to the manual winding drive mechanism. Since the reverse rotation of the handle shaft is prevented by the reverse rotation prevention portion of the friction brake body of the device and the side plate side locking member, the tooth surface of the drive gear of the manual winding drive mechanism is not damaged or deformed. It has become possible to maintain good winding and rotating performance.

Further, the spool-free property is not impaired due to the influence of the twisting load. Furthermore, according to the invention of claim 2, the cylindrical friction braking body accommodating the plurality of braking members is integrally provided with the pinion gear and the reverse rotation preventing portion, whereby the braking portion, the power transmission portion, and the reverse rotation preventing portion are provided. By combining the parts and other parts, the entire reel can be made more compact.
According to the third aspect of the present invention, in the manual / electric combined type reel, the motor power drive unit, the manual winding drive unit, and the drag device can be easily drive-connected without difficulty.
