[0004]

By the way, in an electric transmission, depending on whether the gear ratio of meshing gears is set to a high speed state or a low speed state, torque is insufficient or high speed winding is performed. The problem that performance is inferior is pointed out.

On the other hand, the mechanical transmission requires a structure for turning on / off the drive system of the speed reduction mechanism, which increases the number of parts, complicates the structure, and increases the size and weight of the entire reel. End up. For this reason, problems have been pointed out that fishing operability such as winding and unwinding, portability, and the like are deteriorated and troubles are induced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show a first embodiment of the present invention. As shown in FIG. 1, the electric fishing reel 1 of this embodiment includes a reel body 4 to which a manual handle 2 is attached. Between the left and right frames constituting the reel body 4, the spool shaft 10 is rotatably supported via a bearing 80, and the spool 12 is disposed so as to surround the spool shaft 10.

A spool drive motor (hereinafter simply referred to as a motor) 14 capable of rotating in the forward and reverse directions is held between the left and right frames of the reel body 4. This motor 14
The rotational force of the rotational drive shaft 14a is a transmission mechanism 19 to be described later.
And the first reduction mechanism 15 are transmitted to the drive gear 45. That is, the drive gear 45 is
A rotational force is obtained from the motor 14 and is driven to rotate.

The drive gear 45 is meshed with a spool drive gear 60 that is fixed to one end of the spool shaft 10 via a gear 47. That is, the rotational force of the drive gear 45 is transmitted to the spool shaft 10. Further, between the other end of the spool shaft 10 and the spool 12, the spool 1 is decelerated while reducing the rotational force of the spool shaft 10.
A second speed reduction mechanism 17 having a planetary gear for transmitting to 2 is provided.

Therefore, in the above configuration, when the motor 14 is driven and the rotary drive shaft 14a is rotated, the rotational force is transmitted to the first reduction mechanism 15 via the speed change mechanism 19, and this first While being decelerated by the decelerating mechanism 19, it is transmitted to the drive gear 45 to rotate it. The rotational force of the drive gear 45 is transmitted to the spool 12 through a power transmission mechanism including the gears 47 and 60, the spool shaft, and the second speed reduction mechanism 17, and rotates the spool 12.

In this embodiment, the drive gear 45 rotates in the reverse direction (counterclockwise rotation in FIGS. 3 to 5; the same applies hereinafter).
Then, a plurality of gears constituting the power transmission mechanism are meshed so that the spool 12 rotates in the fishing line winding direction.

Next, the structure of the speed change mechanism 19 will be described in detail.

As shown in an enlarged view in FIG. 2, the speed change mechanism 19 includes a pinion gear 20 that is fixed to the rotation drive shaft (output portion) 14 a of the motor 14 and a pinion gear 2.
A low-speed gear 22 and a high-speed gear 25 that individually mesh with 0, a small-diameter small gear 29 that rotates integrally with the low-speed gear 22, and a large-diameter large gear 35 that rotates integrally with the high-speed gear 25. The rotational speed of the spool 12 is switched between the high speed mode and the low speed mode.

The low-speed gear 22 and the high-speed gear 25 are set to have the same outer diameter (the same gear ratio with the pinion gear 20) (not to mention the same). The low speed gear 22 is connected via the first one-way clutch 23.
The first rotary shaft 24 is rotatably supported. Also,
The high speed gear 25 is rotatably supported by the second rotating shaft 28 via the second one-way clutch 26.

The first rotating shaft 24 is provided with bearings 21 and 4.
3 is rotatably supported between the first frame 50 of the reel body 4 and a carrier 40 described later.
The second rotary shaft 28 is connected to the bearings 27 and 33 through
The first frame 50 and the second frame 5 of the reel body 4
1 is supported so as to be rotatable.

The first one-way clutch 23 and the second one-way clutch 26 are set so that their rotational directions for transmitting force are opposite to each other. That is, for example, when the low speed gear 22 rotates in the reverse direction, the first one-way clutch 23 transmits the rotational force to the first rotating shaft 24 and the low speed gear 22 rotates in the forward direction (the timepieces in FIGS. 3 to 5). Rotation around; the same below)
Then, the rotational force is not transmitted to the first rotating shaft 24. On the other hand, the second one-way clutch 26 is, for example, when the high-speed gear 25 rotates forward,
The rotational force is transmitted to the second rotary shaft 28, and the high speed gear 2
When 5 is reversed, the rotational force is not transmitted to the second rotating shaft 28.

A small gear 29 is fixed to the first rotating shaft 24 so as to rotate integrally therewith. Further, the second rotary shaft 28 has a large gear 3 so as to rotate integrally therewith.
5 is fixed. The large gear 35 is connected to the small gear 2.
9 meshes. The gear ratio between the large gear 35 and the small gear 29 is set so that the ratio between the rotational speed of the spool 12 in the high speed mode and the rotational speed of the spool 12 in the low speed mode becomes a desired value.

As shown in FIG. 1, the reel body 4 is provided with a low speed mode switch S1 and a high speed mode switch S2 as switching operation members for switching modes of the rotational speed of the spool 12. In this case, when the low speed mode switch S1 is turned on, the rotational drive shaft 14a of the motor 14 is rotated forward, and when the high speed mode switch S2 is turned on, the rotational drive shaft 14a of the motor 14 is reversed. Yes.

As shown in FIG. 2, the first reduction mechanism 1
5 is disposed between the sun gear 30 and the second frame 51 and the sun gear 30 which are fixedly fitted to the first rotating shaft 24, and is formed on the sun gear 30 and the second frame 51. A plurality of (three in the present embodiment, see FIG. 3) planetary gears 36 respectively engaged with the internal teeth 31 are provided. The planetary gear 36 is rotatably supported by the carrier 40 via a support shaft 37. The carrier 40 has bearings 41, 4
2 through the second frame 51 and the third frame 52.
It is supported so that it can rotate between. The carrier 40 is fitted with the aforementioned drive gear 45 in a non-rotating manner.

Next, the operation of the electric fishing reel 1 having the above structure will be described with reference to FIGS.

First, when the low-speed mode switch S1 is turned ON, as shown in FIGS. 3 and 4, the rotational drive shaft 14a of the motor 14 is rotated forward. When the rotation drive shaft 14a rotates forward, the low speed gear 22 meshing with the pinion gear 20 is achieved.
And the high speed gear 25 are reversed. At this time, the first one-way clutch 23 transmits the rotation of the low-speed gear 22 to the first rotating shaft 24 by the above-described action, while the second one-way clutch 26 transmits the rotation of the high-speed gear 25 to the second rotation shaft 24. Not transmitted to the rotary shaft 28. Therefore, the first rotating shaft 24 is rotated at a rotational speed corresponding to the rotational speed of the rotational drive shaft 14a and the gear ratio between the pinion gear 20 and the low-speed gear 22, and the low-speed gear 2 is rotated.
2 and the second rotating shaft 28 does not rotate.

When the first rotary shaft 24 rotates in the reverse direction in this way, the small gear 2 fitted to the first rotary shaft 24 is prevented.
9 also reverses, and the large gear 35 meshing with this reversely rotates. As a result, the second rotary shaft 28 to which the large gear 35 is fitted to prevent rotation rotates in the forward direction. In this case, the rotation direction of the second rotating shaft 28 and the rotation direction of the high-speed gear 25 are opposite to each other, but since the second one-way clutch 26 is interposed therebetween, both 25, 28 The rotation is not hindered.

When the first rotating shaft 24 is rotated in the reverse direction, the sun gear 30 fitted to the rotation is rotated in the reverse direction, and the planetary gear 36 meshing with the sun gear 30 is rotated forward with respect to the carrier 40. At this time, since the second frame 51 is fixed, the planetary gear 36 that meshes with the internal teeth 31 formed on the second frame 51 rotates in the forward direction (spinning) while the internal teeth 31 are rotating.
Carrier 4 that receives the reaction force from the side and supports the planetary gear 36
Sun gear 30 while applying a force to reverse this to zero
Revolve around. That is, the rotation of the first rotating shaft 24 is transmitted to the carrier 40 while being decelerated, and the carrier 40
Is reversely rotated integrally with the drive gear 45. That is, the motor 14
Is output to the drive gear 45 while being decelerated by the first speed reduction mechanism 15. In this case, the pinion gear 20 and the low speed gear 2
2 and the small gear 29 together with the first speed reduction mechanism 15 form a low speed reduction gear mechanism with a small gear ratio.
When the drive gear 45 is reversed, the spool 12 is rotated at a predetermined speed (low speed) in the fishing line winding direction via the power transmission mechanism (gears 47, 60, etc.) described above.

On the other hand, when the high-speed mode switch S2 is turned on, the rotational drive shaft 14a of the motor 14 is reversed as shown in FIG. When the rotary drive shaft 14a is reversed,
Both the low speed gear 22 and the high speed gear 25 that mesh with the pinion gear 20 rotate in the forward direction. At this time, the second one-way clutch 26 causes the rotation of the high speed gear 25 to the second speed by the above-described action.
The first one-way clutch 23 does not transmit the rotation of the low speed gear 22 to the first rotation shaft 24.
Therefore, the second rotary shaft 28 rotates forward together with the high speed gear 25 at a rotational speed corresponding to the rotational speed of the rotary drive shaft 14a and the gear ratio between the pinion gear 20 and the high speed gear 25, and the first rotary shaft. 24 does not rotate.

When the second rotating shaft 28 rotates in the forward direction in this way, the large gear 3 fitted to the second rotating shaft 28 is prevented from rotating.
5 also rotates in the forward direction, and the small gear 29 that meshes with it rotates in the reverse direction. Accordingly, the first rotating shaft 24 to which the small gear 29 is fitted to prevent rotation is also reversed. At this time, the rotation speed of the second rotation shaft 28 is amplified by a magnitude corresponding to the gear ratio between the large gear 35 and the small gear 29, and the first rotation shaft 24 is rotated from the small gear 29.
To be told. Therefore, the first rotating shaft 24 is rotated at a speed higher than that in the low speed mode. In this case, the rotation direction of the first rotating shaft 24 and the rotation direction of the low-speed gear 22 are opposite to each other, but the first interposed therebetween.
The one-way clutch 23 does not prevent the rotation of the two and 24.

When the first rotating shaft 24 is rotated in the reverse direction, the sun gear 30 engaged with the rotation of the first rotating shaft 24 is rotated in the reverse direction, and the planetary gear 36 meshing with the sun gear 30 is rotated in the forward direction (rotation). Revolving around, the carrier 40 is integrated with the drive gear 45 and reverses at a higher speed than in the low speed mode.
That is, also in this high speed mode, as in the low speed mode, the small gear 29 is reversed and the drive gear 45 is reversed via the speed reduction mechanism 15. In other words, in this embodiment, the direction of rotation output from the speed change mechanism 19 to the speed reduction mechanism 15 is the same regardless of whether the speed is low or high.

In this high speed mode, the pinion gear 20, the high speed gear 25, the large gear 35, and the small gear 29 are
A high speed reduction gear mechanism with a large gear ratio is configured together with the first reduction mechanism 15. Further, the drive gear 45
Is reversed, the aforementioned power transmission mechanism (gears 47, 60
Etc.), the spool 12 is rotated at a speed (high speed) faster than the low speed mode in the fishing line winding direction.

As described above, in the electric fishing reel 1 of the present embodiment, the gear ratio of the meshing gears is switched depending on the rotation direction of the pinion gear 20, and the first reduction mechanism 1 is switched.
5 is provided, and the rotational speed (winding speed) of the spool 12 can be switched between the high speed mode and the low speed mode only by switching control of the rotational direction of the motor 14. That is, the speed reduction is performed by switching the rotation direction of the motor 14 and using the coupling action of the one-way clutches 23 and 26 without providing an operation mechanism for changing the meshing state of the gears (changing the gear ratio). Since the rotational force of the motor 14 is selectively transmitted to either the gear mechanism or the high speed reduction gear mechanism, the entire reel can be reduced in size and weight without complicating the structure. The fishing operability and portability are improved.

Further, in this embodiment, the speed change is realized only by changing the rotation direction of a part of the meshing gears by switching the rotation direction of the motor 14, so that the switching between the high and low speed modes is smooth (this) On the other hand, since the mechanical transmission changes the meshing state of the gears, there is an impact at the time of switching between the high and low speed modes), and it is possible to avoid a situation where the fish is burred at the time of mode switching.

Further, the electric reel 1 for fishing according to the present embodiment.
The gear ratio of the meshing gears is not set to only one of the high speed state and the low speed state as in an electric transmission, but it has both a low speed reduction gear mechanism and a high speed reduction gear mechanism. Therefore, there is no problem that torque is insufficient or high-speed winding performance is inferior during low-speed rotation. That is, the fishing electric reel 1 of the present embodiment has a structure that corrects the disadvantages of both the mechanical transmission device and the electric transmission device, and takes advantage of both, and increases the size of the motor 14. Therefore, a high torque and high speed winding performance can be obtained. Further, unlike the electric transmission, the winding speed can be switched while the motor 14 maintains full power.

Further, the electric reel 1 for fishing according to the present embodiment.
Are provided on the reel body 4 with switches S1 and S2 for switching the rotation direction of the motor. Therefore,
Switching between high-speed mode and low-speed mode (switching of winding speed)
Can be set arbitrarily by the angler according to the actual winding situation,
A wide range of winding operations can be easily performed.

In the present embodiment, it is desirable that the rotation direction of the motor 14 is automatically switched in accordance with the change in the load acting on the spool 12 when winding the fishing line. That is, a known tension measuring device for measuring the tension of the fishing line (for example, a spool 12 bearing provided with a strain gauge) is provided, and when a torque is applied in the direction of feeding the fishing line, or the fishing line is tensioned. If it is, it is preferable to automatically switch to the low speed mode (the motor 14 rotates forward). According to this, since the rotation direction of the motor 14 changes according to the load at the time of actual fishing line winding, and automatically switches between the high speed mode and the low speed mode, the optimum winding according to the load acting on the fishing line is achieved. The winding operation can be performed without trouble under certain conditions.

In this embodiment, the motor 14
It is desirable to provide motor output adjusting means (power lever or the like) for increasing or decreasing the output of. According to this,
Since it is possible to perform two systems of combined operations of switching between high and low speed modes and increasing / decreasing motor power, the performance of the motor 14 can be maximized, and a wide and delicate winding operation can be performed. That is, the range of speed change is widened, and high-speed and high-torque winding performance can be easily obtained.

In this embodiment, the motor 14 is set to the low speed mode during the forward rotation and is set to the high speed mode during the reverse rotation. However, this form may be reversed. That is, the motor 14 may be set to the low speed mode during the reverse rotation and set to the high speed mode during the normal rotation.

FIG. 6 shows a second embodiment of the present invention. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

In the first embodiment, the one-way clutches 23 and 26 are provided on a separate shaft from the motor 14, but in this embodiment, the one-way clutches 23 and 26 are provided coaxially with the motor 14. . In this case, a gear 70 meshing with the low speed gear 22 is fixed to the first rotating shaft 24 and a gear 72 meshing with the high speed gear 25 is fixed to the second rotating shaft 28. . The other configuration is the same as that of the first embodiment, and therefore the same effect as that of the first embodiment can be obtained.
