2. Description of the Related Art Conventionally, a clutch mechanism in a fishing dual bearing reel is disclosed in Japanese Patent Publication No. 6-59155, which discloses an inner end of a handle shaft to which a manual handle is attached or an inner end of the handle shaft. A return pin or a ratchet gear provided at the inner end of an electric gear arranged so as to be coaxially driven and actuated actuates a cam plate connected to a clutch operation lever, and is coupled to a pinion gear by a cam of the cam plate. By operating the shifter, the pinion gear and the spool are driven and connected, and the clutch mechanism in the spool free fishing line unwinding state is switched to the fishing line winding state.

However, as described above, when the return pin or ratchet gear for operating the cam plate and the shifter or pinion gear operated by the cam plate are arranged in parallel and are not arranged coaxially, the operation of the cam plate is not performed. Due to restrictions on the arrangement of various operating members around the pinion gear, such as the direction and shifter arrangement, this design required a great deal of labor as well as skill.

A clutch mechanism has been proposed.

However, the above-mentioned clutch mechanism in which the clutch mechanism is switched by a pinion shaft which is drivingly connected to a motor shaft requires not only a mechanism for manually switching to a state in which the clutch mechanism is driven and connected to the spool, but also requires a separate mechanism for winding the fishing line. Since the pinion shaft is always operated during driving of the spool drive motor, a problem arises in that peripheral members such as the pinion shaft and bearings for supporting the pinion shaft must be strengthened. There is also a problem that the diameter must be increased.

The handle shaft 5a has a plurality of friction plates. The main gear 8 is rotatable mutually via a drag mechanism 7 comprising
2A and 3A are rotatable only in the fishing line winding direction indicated by an arrow A in FIGS. 2A and 3A.
The drag mechanism 7 corrects a drag adjustment knob 7a screwed into the vicinity of the manual handle 5 of the handle shaft 5a.
By reversing the rotation, the frictional force between the plurality of friction plates is adjusted so that the braking force between the handle shaft 5a and the main gear 8 can be adjusted. The main gear 8 is integrally rotatable with a second arm ring 23 of the planetary gear reduction mechanism 10 which is incorporated in a motor shaft 31a of a spool drive motor 31 described later and rotatably supported on the side plate 3b via a bearing. The gear is meshed with the first gear 19 provided in.

Here, the planetary gear reduction mechanism 10 incorporated in the motor shaft 31a of the spool drive motor 31 will be described. The spool drive motor 31 is integrated between the left and right frame plates 2a, 2b of the frame 2. The motor shaft 31a is non-rotatably accommodated in a motor case 2d which is mounted in a fixed manner, and the motor shaft 31a is moved in only one direction by a one-way clutch 13 provided between the end of the left frame plate 2a and the motor case 3d. It is provided rotatable. A first sun gear 27 is fixed to an end of the motor shaft 31a on the right frame plate 2b side,
The first sun gear 27 has a shaft 46a extended toward the spool drive motor 31 at a position eccentric from the rotation axis of a substantially disk-shaped portion of a first arm ring 46 rotatably mounted on the motor shaft 31a. Plurality of first planetary gears 25 rotatably supported
Are meshed so as to surround the first sun gear 27, and the first planetary gear 25 is always meshed with the internal gear 20 rotatably supported by the bearing 14 on the motor case 2d.
On the other side of the first bracelet 46, a second sun gear 26 that rotates integrally is provided.

Of the second planetary gear 24 is the second sun gear 26
, And the second planetary gear 24 is also always meshed with the internal gear 20.

On the outer periphery of the internal gear 20, an internal gear 2
0, and a gear 66 that can rotate integrally with the gear 66 is provided.
Is a connecting gear 28 provided to be supported by the reel body 1.
The connection gear 28 meshes with the gear portion 6a of the pinion gear 6 of the drive connection end member.
The internal gear 20 has a gear 16 so that it rotates coaxially and integrally.
The gear 16 meshes with a driven gear 32 fixed to an end of a traverse cam shaft 29a of the level wind mechanism 29.

Accordingly, when the spool drive motor 31 is driven, the rotation of the motor shaft 31a in the forward rotation direction is the first rotation.
By rotating the sun gear 27 and rotating the first planetary gear 25, the first planetary gear 25 revolves around the first sun gear 27 together with the first arm ring 46 while meshing with the internal gear 20 and the first sun gear 27. Rotating the second sun gear 26 on the other side of 46,

The second arm ring 23 is rotated through the second arm ring 23, and the second planetary gear 24 supported by the second arm ring 23 is rotated while revolving around a second sun gear 26 meshed therewith. At this time, the revolving motion of the second planetary gear 24 is transmitted from the second sun gear 26 to the motor shaft 31a, but since the motor shaft 31a is prevented from rotating by the one-way clutch 13, the second planetary gear 24 Rotates the internal gear 10 while revolving around the second sun gear 26 in a non-rotating state, thereby rotating the pinion gear 6 in the same manner as when the spool drive motor 31 is driven. Activate the wind mechanism 29.

Next, the clutch mechanism according to the present invention will be described. The pinion gear 6 is mounted on the spool shaft 4a so as to be slidable in the axial direction.
A clutch recess 15b is formed on the end face opposite to the clutch shaft 15a to be engaged with the clutch pin 15a implanted in a direction intersecting with the spool shaft 4a. As shown in FIG. 2, the clutch pin 15a and the clutch recess 15b are joined. In this state, the pinion gear 6 is stopped by the spool shaft 4a, and the pinion gear 6 and the spool 4 are configured to rotate integrally. As shown in FIG.
5a and the clutch recess 15b are not connected,
The spool 4 provided integrally with the spool shaft 4a is configured to be freely rotatable.

An annular groove 6a is formed near the other end of the pinion gear 6, and a shifter 41 is rotatably and non-slidably engaged with the annular groove 6a.

b, a pair of shafts 41 erected in parallel with the spool shaft 4a.
a, 41a slidably supported by the shafts 41a,
The clutch pin 15a and the clutch recess 15b are constantly urged by the springs 41b and 41b provided on the outer surface of the clutch 41a in a direction in which the clutch pin 15a and the clutch concave portion 15b try to be engaged.

Further, a spool OFF lever 15c, which is vertically movable between the right and left frame plates 2a and 2b of the reel body 1, is pushed down between the right frame plate 3b and the shifter 41, thereby causing the spool to be depressed. Clutch OFF position and clutch ON with the same shaft center as shaft 4a and pinion gear 6.
The cam plate 40 is rotatably supported at a position, and is biased to two positions of a clutch OFF position and a clutch ON position by a dead point spring 40b (FIGS. 2A and 3A). The pinion gear 6 is moved together with the shifter 41 by the action of cams 40a, 40a projecting from the surface of the spring 41b, 41 facing the shifter 41.

The spool 5 is moved in the axial direction of the spool shaft 4a so that the clutch recess 15b is disengaged from the clutch recess 15b to cut off the drive connection between the pinion gear 6 and the spool 4 and switch to the spool free rotation state.

Further, as shown in FIGS. 2B and 3B, a tapered portion 6b having a large diameter at the center and a small diameter at the annular groove is formed at the center of the annular groove 6a formed at the other end of the pinion gear 6. When the pinion gear 6 is in the clutch ON state, the cam plate 40 is rotatably fitted on the small-diameter outer peripheral surface of the tapered portion 6b, and when the pinion gear 6 is in the clutch OFF state, the cam plate 40 is engaged. The large-diameter outer peripheral surface is engaged with the cam plate 40 so that the pinion gear 6 and the cam plate 4
0 is formed so as to be able to rotate integrally with the spool shaft 4a.

Therefore, the clutch mechanism 1 according to this embodiment is
Reference numeral 5 denotes a clutch pin 15a on the spool 4 side and a pinion gear 6 which are urged by a spring 41b, 41b urged by a shifter 41 rotatably engaged near the other end of the pinion gear 6 when the clutch is ON. Since the clutch recess 15b at one end is engaged and the cam plate 40 is rotatably fitted on the small-diameter outer peripheral surface of the tapered portion 6b of the pinion gear 6, the cam plate 40 is driven by the manual handle 5 or the spool drive motor 31. The spool 4 can be driven to wind with the winding drive of the pinion gear 6, and the fishing line can be wound on the spool.

When the cam plate 40 is rotated by pushing down the clutch OFF lever 15c, the cam 40a of the cam plate 40 causes the pinion gear 6 and the shifter 41 to move on the spool shaft against the spring force of the springs 41b, 41b. Sliding movement causes clutch pin 15a on spool 4 side
Is disengaged from the clutch recess 15b at one end of the pinion gear 6, and the clutch is switched to the OFF state, so that the fishing line wound on the spool 4 in the free spool rotation state can be fed out by its own weight such as a tackle or a weight. At the same time, the large-diameter outer peripheral surface of the tapered portion 6b of the pinion gear 6 is
It is engaged so as to be able to rotate integrally with 0.

In this state, when a signal for rotating the spool drive motor 31 by a predetermined amount is sent to drive the spool drive motor 31 by a predetermined amount, or when the manual handle 5 is wound up, the spool drive motor 31 or When the pinion gear 6 is driven by the operation of the manual handle 5, the cam plate 40 is rotated by a predetermined amount, and the cam 40a of the cam plate 40 is disengaged from the shifter 41 to move on the spool shaft by the spring force of the springs 41b and 41b. The pinion gear 6 slides back to engage the clutch pin 15a on the spool 4 side with the clutch recess 15b at one end of the pinion gear 6, and the pinion gear 6 moves with the slide return of the pinion gear 6.
The engagement between the large diameter outer peripheral surface of the tapered portion 6b and the cam plate 40 is also released, the clutch is switched to the ON state, and the feeding of the fishing line from the spool is stopped.

The rotation drive signal for the predetermined amount to the spool drive motor 31 at the time of switching from the clutch OFF state to the clutch ON state in the previous operation is a feeding fishing line measured by a known fishing line feeding length measuring device (not shown). A comparison match signal between the length and a preset fishing line payout length,
Alternatively, a comparison coincidence signal between the spool rotation speed counted by a known spool rotation speed counting means (not shown) and a preset spool rotation speed, or a control panel 50 (FIGS. 2A and 3A) formed on the upper surface of the reel body 1 Provided shelf stop switch 51
In addition, the fishing line winding signal of the spool drive motor 31 at the time of winding the fishing line is continuously driven by an auto switch pressing signal received by the control panel 50 as in the conventional case. May be driven only by the pressing signal of the manual switch at the time of pressing, or may be an operation signal of an operation of a shift lever provided rotatably or slidably on the reel body 1 or the like.

In the embodiment, reference numeral 52 denotes a cam plate 4
0 is a one-way clutch interposed between the pinion gear 6 and the pinion gear 6 in order to ensure and facilitate the engagement, and is not an essential element in the present invention.

When the cam plate 40 is switched to the clutch OFF state, the kick claw 54 (FIG. 2A, The clutch mechanism 15 is switched from the clutch 0FF state to the clutch-on state by pushing the clutch mechanism 15 out of the rotation locus (FIG. 3A), but this clutch switching mechanism is not an essential element in the present invention. .

In the present embodiment, a magnet is provided on the cam plate 40, and the magnet provided on the cam plate is provided on the right frame plate or the right side plate corresponding to the clutch OFF position or the clutch ON position or both positions. By providing a detecting means such as a reed switch, the operation accuracy may be improved. In this embodiment, the spool shaft 4a
Is held by the left frame plate 2a and the right plate 3b, and the pinion gear 6 is supported by the spool shaft 4a. However, the spool shaft 4a is held by the left and right frame plates 2a, 2b as already known. The pinion gear 6 may be separately provided on the same axis as the spool shaft 4a and supported by a pinion shaft held by the right frame plate 2b and the right plate 3b.
In this embodiment, the coupling and disengagement of the spool 4 and the pinion gear 6 in the clutch mechanism 15 are performed by a clutch pin 15a planted in a direction intersecting with the spool shaft 4a and a clutch recess 15b formed at one end of the pinion gear 6. However, the engagement and disengagement portions formed on the right side surface of the spool 4 and the opposing surface of the pinion gear 6 may be connected and separated in a known manner.

In this embodiment, a manual drive coupling mechanism for transmitting rotation from the manual handle 5 or the spool drive motor 31 to the spool 4 is provided near the right side plate 3b on which the manual handle 5 is provided. Since the mechanism, the clutch mechanism, and the drive connection mechanism of the level wind mechanism are housed, there is no need to house any members necessary for driving the reel at a position near the left side plate 3a where the manual handle 5 is not provided. There is no need to provide a space for accommodating members. Therefore, the outer shape of the left side plate 3a can be reduced in size, and the holding ability of the left side plate 3a at the time of winding the fishing line can be improved.

The drive connection mechanism and the like required for driving the electric reel are collectively stored in the vicinity of the right side plate 3b provided with the manual handle 5, so that the drive connection mechanisms provided in the vicinity of the left and right side plates 3a and 3b are provided. There is no need to extend a drive shaft or the like for connecting the mechanisms between the left and right side plates 3a, 3b, so that the number of parts can be reduced, the mechanism can be simplified, and the weight can be reduced.

Further, since the drive connection mechanism and the like necessary for driving the electric reel are assembled in the vicinity of the right side plate 3b provided with the manual handle 5, the operation of assembling them into the reel body can be simplified. In addition, repairs in the event of malfunction or maintenance after use can be easily performed not only by removing the right side plate 3b provided with the manual handle 5, but also during cleaning of the fishing line after fishing and during fishing. The attachment and detachment of the spool for replacing the fishing line can be performed only by disassembling the left side ear side plate 3b side.

Since the level wind mechanism 29 is provided, the fishing line can be uniformly wound on the spool 4. However, a drive connection mechanism for drivingly connecting the level wind mechanism 29 and the spool drive motor 31 is also provided. Since it is stored near the right side plate 3b provided with the manual handle 5,
Repair or the like can be easily performed by simply removing the right side plate 3b even when the level wind mechanism is malfunctioning or during maintenance.

In the electric fishing reel according to the present embodiment, even when the spool line is being wound by the spool drive motor 31, the manual handle 5 can be rotated in the fishing line winding direction. Therefore, the operation of the spool 4 and the level wind mechanism 29 by the spool drive motor 31
Since the operation of the spool 4 and the level wind mechanism 29 by the rotation of the manual handle 5 in the fishing line winding direction can be used together, additional winding can be performed at either one of the high-speed rotation speeds, and only quick reversal is possible. In addition, it is possible to prevent burnout due to an excessive load on the spool drive motor 31.

The reel leg 39 of the electric fishing reel according to the present embodiment is provided at the lower portion of the reel body 1 and substantially at the center of the reel body 1 in the left-right direction. That is, it may be provided close to the right side plate 3b to which the manual handle 5 is attached. Providing the reel leg 39 at the center of gravity in this manner improves the balance when the fishing rod is mounted, and also improves the balance between the fishing rod equipped with the reel and the manual handle 5.
Can be made close to each other, so that the winding operation of the fishing line by the manual handle 5 can be stabilized.

On the opposing surfaces of the pinion gear 6 and the gear 50a, meshable concave and convex portions 6b 'and 50c are provided, respectively. The pinion gear 6 moved against the spring force meshes with the gear 50a.

On the other hand, when the clutch mechanism 15 is switched on by operating the clutch lever 15c as shown in FIG. 5, the pinion gear 6 moves on the spool shaft 4a toward the spool 4 by the restoring force of the spring 41b, and the right side of the spool 4 At the same time, the gear 50a is also moved by the restoring force of the spring 51, and the engagement between the pinion gear 6 and the gear 50a is released.

A single gear 50b meshing with the gear 50a is rotatably mounted inside the right plate 3b, and the gear 50b has a structure further meshing with the gear 15e. When the clutch lever 15c is in the clutch OFF position and the pinion gear 6 and the gear 5
When the winding power is transmitted to the pinion gear 6 via the handle shaft 5a and the main gear 8 when the manual handle is rotated when the gears 0a and 0a are meshed with each other, the power transmission mechanism 5
The gear 15e is transmitted to the gear 15e via the 0 gears 50a and 50b, and the gear 15e rotates in the direction of the arrow H as shown in FIG. 6B to return the clutch lever 15c to the clutch ON position. .

Accordingly, the return of the clutch lever 15e causes the eccentric pin 15d protruding from the gear 15e to move to the cam plate 40.
Is moved in the direction of arrow G as shown in FIG. 6B, and the cam 40a of the cam plate 40 is disengaged from the shifter 41 to switch to the clutch ON state.

In the figure, reference numeral 60 denotes a magnet mounted on the cam plate 40, and a reed switch 61 which is turned on and off by the magnet 40 is mounted on a guide member 40f of the cam plate 40, and the cam plate 40 moves. Depending on the position, the clutch ON state or clutch OFF state can be detected.

The double bearing reel for fishing in this embodiment is
Because it is configured as above, to do fishing,
First, the clutch lever 15c is moved to the clutch O shown in FIG.
By operating in the FF state, the coupling between the spool 4 and the pinion gear 6 is released by the cam plate 40 and the clutch is turned off, and the spool 4 is freely rotated. It is paid out from spool 4.

Therefore, when the angler returns the clutch lever 15c to the clutch ON state shown in FIG. 6A at a predetermined water depth, the spool 4 and the pinion gear 6 are connected to each other, the clutch is turned ON, and the spool 4 is wound up. You. If the manual handle is wound, the gear 15e is transmitted from the pinion gear 6 to the gear 15e via the gears 50a and 50b, and the gear 15e rotates in the direction of arrow H in FIG. 6B to return the clutch lever 15c to the clutch ON state. Gear 1
