Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly to an improvement of a fishing reel provided with a drag mechanism that applies a braking force to the rotation of a spool around which fishing line is wound.

[0002]

2. Description of the Related Art Generally, a fishing reel is equipped with a drag mechanism for applying a braking force to the rotation of a spool in a line-feeding direction. In such a drag mechanism, a rotating body such as a spool or a drive gear is rotatably frictionally coupled to a support shaft of the reel unit, and the drag force can be adjusted by changing the frictionally coupled state. ing.

The drag mechanism is generally an adjusting member (star drag or the like) screwed onto the handle shaft of the winding drive mechanism.
Can be roughly classified into a method of adjusting the braking force by a rotating operation and a method of adjusting the braking force by a rotating operation of a lever-shaped adjusting member rotatably supported on one side of the reel unit.

The former method is mainly used for small to medium-sized reels because the adjusting member can be easily rotated while the handle is held. In contrast,
The latter method is widely used mainly for medium-sized to large-sized reels because it can be adjusted while holding the reel body and a large force can be easily applied only by rotating the lever.

The latter type of drag mechanism used for medium to large reels includes, for example, Japanese Utility Model Publication No. 4-259.
As disclosed in Japanese Patent Laid-Open No. 77-77, the spool is axially displaced by a turning operation of a lever-shaped adjusting member to adjust the pressure contact force of a single plate, or an actual flat blade 2-1201.
As disclosed in Japanese Patent Laid-Open No. 64, there is known one in which a plurality of braking plates are accommodated in a reel body accommodating portion on a drive shaft of a power transmission mechanism (planetary gear support).

[0006]

However, the drag mechanism of the type disclosed in the above-mentioned two publications has some problems as described below.

That is, in the drag mechanism disclosed in Japanese Utility Model Publication No. 4-25977, since the spool is displaced in the axial direction, a level wind mechanism (parallel winding device) for uniformly winding the fishing line on the spool may be incorporated. Have difficulty.
Further, since the drag mechanism is provided near the spool that is constantly exposed to seawater, it is difficult to waterproof the drag mechanism. Furthermore, when increasing the gear ratio to increase the winding speed, it is necessary to increase the diameter of the drive gear, which may result in an increase in the size of the entire reel.

The drag mechanism of Japanese Utility Model Laid-Open No. 2-120164 is disclosed as an example of application to an electric reel. However, a braking member constituting the drag mechanism is formed in a cylindrical portion integrally formed with the reel body or in an interlocking gear. Since it is housed inside, the degree of freedom in design is restricted, such as the material and position of the tubular part being restricted. In addition, manual winding is impossible, and even if a manual winding drive mechanism is installed, it is difficult to equip it easily and compactly. May increase in size).

The present invention has been made in view of the above circumstances, and its main purpose is to increase the manual winding drive mechanism without increasing the size of the main body and without impairing the degree of freedom in design. It is an object of the present invention to provide a fishing reel capable of speeding up and easily waterproofing a drag mechanism. Another object of the present invention is to provide a fishing reel capable of both electric winding and manual winding while achieving the main purpose.

[0010]

In order to solve the above-mentioned problems, the present invention provides a spool which is rotatably supported between both side plates of a reel body and a rotating operation of a handle provided on the one side plate. In a fishing reel including a manual winding drive unit configured to rotate the spool in a fishing line winding direction, a planetary gear transmission mechanism provided between the spool and the manual winding drive unit. A drive shaft that transmits the power of the manual winding drive unit to the planetary gear transmission mechanism; and a drag mechanism that is provided on the drive shaft and that applies a braking force to the rotation of the spool in the fishing line feeding direction, The power of the manual winding drive unit is transmitted from the drag mechanism to the planetary gear transmission mechanism via the drive shaft to rotate the spool in the fishing line winding direction.

A pinion gear 38 is fitted to the outer peripheral surface of the pressing body 24 via a locking pin 37. That is, the pinion gear 38 can rotate integrally with the pressing body 24. The drive gear 66 of the manual winding drive unit 150 meshes with the pinion gear 38.

The manual winding drive unit 150 includes a handle H
And a handle shaft 65 that rotates integrally with the handle H, and a drive gear 66 that is fitted in the handle shaft 65 to prevent rotation.

Further, at the base end of the handle shaft 65, when the spool 8 is rotated in the fishing line winding direction by the spool driving motor 10, the handle shaft 65 is not rotated in association with the reverse rotation. A prevention mechanism is provided. This reverse rotation preventing mechanism includes a ratchet gear 67 having ratchet pawls 67a formed on the outer peripheral surface at a predetermined pitch, and a stopper (not shown) that is constantly engaged with the ratchet pawl 67a with a constant biasing force.

When the spool 8 is rotated in the fishing line winding direction by
In the rotation direction, the stopper engages with the ratchet pawl 67a in the locking direction, so that the ratchet gear 67 is prevented from rotating and the handle shaft 65 is prevented from rotating in association with the rotation of the spool driving motor 10. . Therefore, the power of the spool driving motor 10 is reduced by the speed reduction mechanism 40.
Is transmitted only to the spool 8 via. On the other hand, when the spool 8 is rotated in the fishing line winding direction by the rotation operation of the manual handle H, the stopper engaged with the ratchet pawl 67a in the rotation direction is the ratchet gear 67.
Since the rotation of the handle shaft 54 is allowed, the handle shaft 54 can be rotated in conjunction with the rotation operation of the manual handle H.

As shown in FIG. 1, the spool 8
A level wind mechanism 95 that operates in conjunction with the rotation of the spool 8 is provided in front of. The level wind mechanism 95 includes a worm shaft having a traverse groove formed on an outer peripheral surface thereof and a gear 121 attached to an end thereof, a tubular body 120 for accommodating the worm shaft, and the worm shaft engaging with the traverse groove. Engagement member 128 that slides left and right along the tubular body 120 by rotation of the shaft
And has a hole 128a formed in the engaging element 128.
The fishing line wound around the spool 8 is guided via the. Therefore, when the handle H is rotated, the spool 8 is rotated and the engaging member 128 is slid to the left and right, whereby the spool 8 is rotated.
The fishing line is evenly wound around.

Next, the operation of the fishing reel 1 having the above-described structure during actual fishing will be described.

First, when the drag operating member 27 is rotationally operated in one direction, the first cam member 29 fitted in the drag operating member 27 to prevent rotation is rotated, and accordingly, the second cam member 30 is rotationally driven. It moves in the axial direction of the shaft 45. As a result, the bearing 28, the leaf spring 25, and the pressing body 24 are moved in the axial direction against the biasing force of the compression coil spring 26, and the pressing body 24 is pressed.
The brake plates 21A, 21B, 22 are pressed by the brake plates. As a result, the braking plates 21A, 21B and 22 are rotated by the rotary drive shaft 4
5 is slid along the axial direction, and the braking plates 21A, 21
The friction surfaces of B and 22 are pressed against each other via the lining material 23, and the braking plate 21A is pressed against the container 20 with a predetermined pressing force. Then, the pressing force at this time acts on the rotary drive shaft 45 via the braking plate 22, so that the components of the pressing mechanism including the pressing body 24 are frictionally coupled to the rotary drive shaft 45, and the spool 8 is predetermined. The drag force of is generated.

When the manual handle H is rotated clockwise with the predetermined drag force thus formed, the drive gear 66 and the pinion gear 38 meshing with the drive gear 66 are rotated, and the pressing body integral with the pinion gear 38 is rotated. 24 rotates. Then, the rotational force of the pressing body 24 is transmitted to the rotary drive shaft 45 in accordance with the frictional coupling force by the press mechanism, and rotates the third carrier 62 connected to the rotary drive shaft 45 counterclockwise. . At this time, the planetary gear 59 rotates counterclockwise and revolves around, and rotationally drives the internal gear 52 with the counterclockwise speed increased.
As a result, the spool 8 is rotationally driven in the fishing line winding direction. It should be noted that the first sun gear 50 tries to rotate clockwise by the counterclockwise rotational drive of the internal gear 52, but the rotational drive is performed by the one-way clutch 90 located on the opposite side of the motor 10. Regulated by.

When the spool driving motor 10 is driven in the normal direction (clockwise) regardless of the manual handle H, the first sun gear 50 is rotationally driven in the clockwise direction. By this rotational drive, the planetary gear 51 rotates counterclockwise and revolves clockwise, and the third sun gear 58 rotates clockwise. In this rotation direction, since the rotation of the handle shaft 65 is restricted by the above-described reverse rotation preventing mechanism, the rotation of the pinion gear 38 (pressing body 24) connected to the handle shaft 65 via the drive gear 66 (clockwise rotation). Is regulated. As a result, the rotary drive shaft 45 frictionally coupled to the pinion gear 38 and the third carrier 62.
Is kept stationary in a fixed position without rotating. Therefore, when the third sun gear 58 rotates in the clockwise direction, the plurality of planetary gears 59 rotatably supported by the third carrier 62 do not revolve around the third sun gear 58 and have a fixed position. And rotate counterclockwise.

In this state, the counterclockwise rotational movements of the plurality of planetary gears 59 are decelerated and transmitted to the internal gear 52 engraved on the end face of the spool 8.
Rotate 2 counterclockwise. Along with this, the spool 8 rotates in the fishing line winding direction (counterclockwise).
As a result, the fishing line is evenly wound around the spool 8 via a fishing line guide mechanism (not shown). During such electric winding, the manual rotation handle H does not rotate at a high speed because the reverse rotation prevention mechanism functions.

On the other hand, when the drag operating member 27 is rotated in the other direction, the pressing body 24 is pushed back by the urging force of the compression coil spring 26, and the braking plates 21A, 21B, 22.
The two are separated from each other. Therefore, the frictional coupling force between the components of the pressing mechanism including the pressing body 24 and the rotary drive shaft 45, that is, the drag force is weakened. Then, the drag operation member 27
When the spool is fully rotated in the other direction, finally the spool 8
Is maintained in a freely rotatable state. In this state, the fishing line can be paid out from the spool 8 by a free fall of the tackle.

As described above, in the fishing reel 1 of the present embodiment, the speed reduction mechanism 40 composed of the planetary gear mechanism is provided between the spool 8 and the manual winding drive section 150, and the manual operation is performed. The drag mechanism 16 is mounted on the rotary drive shaft 45 that transmits the power of the winding drive unit 150 to the reduction mechanism 40.
0 is provided, and the spool 8 is rotated in the fishing line winding direction by transmitting the power of the manual winding drive unit 150 from the drag mechanism 160 to the reduction mechanism 40 via the rotation drive shaft 45.

In this way, if the power of the manual winding drive unit 150 is transmitted to the spool 8 via the planetary gear mechanism, the speed of the manual winding drive mechanism can be increased without increasing the size of the entire reel. Can be done easily. Further, since the drag mechanism 160 is not provided near the spool 8 which is constantly exposed to seawater or the like, the drag mechanism 160 can be easily waterproofed. In fact, in the present embodiment, the seal member 80 is provided at the one end opening of the accommodation portion 20a of the accommodation body 20, and the outer peripheral surface portion of the rotary drive shaft 45 to which the accommodation body 20 and the pressing body 24 are fitted is O. Since the rings 82 and 84 are arranged, the drag mechanism 160
The waterproofness of can be significantly improved.

In particular, in this embodiment, the rotary drive shaft 45
, But also serves as a third carrier 62 that supports the planetary gear 59 of the reduction mechanism 40. That is, the rotary drive shaft 45 is
It is connected to the third carrier 62 and rotates integrally with this carrier 62. Moreover, the motor 10 is provided inside the spool 8, and the rotary shafts 10a and 10b of the motor 10 and the rotary drive shaft 45 are coaxially arranged. Therefore, these electric winding mechanisms including the motor 10 are attached to the reel unit 4
Not only can it be compactly installed inside, but the manual winding drive mechanism 150 can be simply and compactly installed on the electric reel 1 equipped with such an electric winding mechanism. Makes the entire reel compact (prevents an increase in the size of the entire reel) without sacrificing design flexibility while allowing the functions to coexist.
be able to.

Further, in this embodiment, the drag mechanism 160
A drag operating member 27 for adjusting the braking force is attached to the right side plate 4a ′ of the reel unit 4 so as to be rotatable in the front-rear direction. Therefore, it is possible to smoothly perform a favorable series of complex fishing operations of the manual winding operation and the drag adjusting operation.

Further, since the fishing reel 1 of the present embodiment does not have the form in which the spool 8 is axially displaced to apply the drag force, the level wind mechanism 95 for uniformly winding the fishing line on the spool is easy. Can be incorporated into.

Further, in this embodiment, the braking plates 21A, 2
Since the 1B and 22 and the lining material 23 are accommodated in the accommodating body 20 that is separate from the reel body 4, the drag mechanism 160 can be equipped without restricting the degree of freedom in design.

Needless to say, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, the present invention is applied to the electric reel, but the present invention can also be applied to the non-electric reel (manual reel). Further, in the above-described embodiment, an example in which the spool drive motor 10 is housed in the spool 8 is shown, but the spool drive motor 10 may be provided outside the spool 8.

[0044]

As described above, according to the fishing reel of the present invention, the speed of the manual winding drive mechanism can be increased without increasing the size of the main body and without impairing the degree of freedom in design. Also, the drag mechanism can be easily waterproofed. Further, it is possible to perform both electric winding and manual winding while achieving these effects.
