Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a clutch ON / O.
The present invention relates to a fishing dual-bearing reel having a clutch mechanism capable of smoothly and reliably performing an FF switching operation.

[0002]

2. Description of the Related Art Conventionally, a dual-bearing type reel for fishing has been disclosed in, for example, Japanese Patent Laid-Open No. 58-71832 and Japanese Utility Model Laid-Open No. 63-107.
As disclosed in Japanese Patent No. 172, there is provided a clutch mechanism capable of engaging and disengaging the spool shaft and the pinion with a return actuating piece biased by a predetermined spring force.

With such a structure, when the spool shaft and the pinion are not engaged (clutch OFF state), the return actuating piece engages with the return rotary member provided on the handle shaft. ing. Then, when the return rotary body is rotated from this state via the handle shaft, the return rotary body pushes back the return operating piece, whereby the engagement between the return operating piece and the return rotating body is released. As a result, the spool shaft and the pinion are in the engaged state (clutch ON state)
Will be returned to.

In such a dual-bearing type fishing reel, in order to confirm the free rotation performance of the spool when the clutch is OFF, for example, at the store, when the handle shaft is rotated at a high speed in the clutch ON state, or at a predetermined time. The operation of disengaging the clutch (clutch OFF operation) is performed at the timing. In this case, that is, when the clutch is switched from the ON state to the OFF state, the above-mentioned return actuating piece is gradually engaged with the return rotating body by the spring force while interlocking with the clutch switching operation.

During this engaging operation, the return rotary member is rotating at a high speed, so that the return operating piece cannot engage with the return rotary member (that is, the clutch cannot be disengaged). , There is a case that it becomes a half clutch state. In this case, the return actuating piece continuously or intermittently contacts the return rotating body that is rotating at a high speed, so that not only abnormal noise is generated but also contact with the return rotating body. The contact portion of the operating piece for restoration that is worn out is worn or damaged. Such a half-clutch state is a problem that occurs even when the clutch lever is erroneously pressed during a matching operation or a fishing line winding operation, and there is an urgent need for improvement.

Therefore, in order to improve such a problem, for example, Japanese Utility Model Registration No. 3021083 discloses:
A clutch mechanism has been proposed in which the timing for engaging the return actuating piece with the return rotating body is delayed so that the half-clutch state is unlikely to occur.

[0007]

However, even in the clutch mechanism proposed in Utility Model Registration No. 3021083, when the clutch is switched from the ON state to the OFF state, the return operating piece is interlocked with the clutch switching operation. Meanwhile, the spring force gradually engages the return rotary body. In this case, the spring force acting on the return actuating piece also gradually decreases, so that the engaging force of the return actuating piece with respect to the returning rotating body rotating at high speed becomes weak. As a result, although the problem that the clutch can be in the half-clutch state is slightly alleviated as compared with the conventional clutch mechanism, the clutch cannot be smoothly and reliably disengaged, and the clutch may be in the half-clutch state. .

The present invention has been made to solve such a problem, and an object thereof is to delay the timing at which the return actuating piece is engaged with the return rotary member and to act on the return actuating piece. An object of the present invention is to provide a dual-bearing type fishing reel equipped with a clutch mechanism capable of smoothly and reliably performing a clutch ON / OFF switching operation by increasing a spring force.

[0009]

In order to achieve such an object, a dual-bearing type fishing reel according to the present invention has a rotating body for return provided on a handle shaft and a clutch ON / OFF.
Clutch cam that rotates in conjunction with operation and clutch ON
When the clutch is switched from OFF to the clutch OFF state, a return operation piece having an engagement portion that engages with the return rotation body and a desired engagement portion when engaging the engagement portion of the return operation piece with the return rotation body And a biasing spring for applying the engaging force of No. 1 to the engaging portion of the return actuating piece, and the clutch cam resists the spring force of the biasing spring when switching from clutch ON to clutch OFF. There is provided an operation restricting portion that can be engaged after the engaging portion of the return operation piece is separated from the return rotating body.

The clutch plate 23 can be moved along the guide shafts 56a and 56b against the urging force of the urging spring. Specifically, in the clutch ON state, the clutch plate 23 is pressed and moved toward the clutch cam 52 by the urging force of the urging spring. Since the clutch plate 23 is engaged with the circumferential groove 21b of the pinion gear 21 as described above, the clutch plate 23
However, the pinion gear 21 can be engaged with the spool shaft 8 by being pressed and moved in the direction of the clutch cam 52. When the clutch ON state is switched to the clutch OFF state, the surface cam 58 interlocks with the rotation of the clutch cam 52 in a direction in which the surface of the clutch plate 23 is separated from the clutch cam 52 against the urging force of the urging spring. By pressing and moving, the engagement state between the pinion gear 21 and the spool shaft 8 can be released.

A hold spring 60 is provided in the clutch mechanism in order to hold the clutch cam 52 at the clutch ON position and the clutch OFF position during such a clutch ON / OFF operation. The hold spring 60 has one end supported by the clutch cam 52 and the other end supported by a support portion 62 formed on the flange 64 of the right frame 3b. This hold spring 60 applies a spring force in the direction of arrow S1 in the figure to the clutch cam 52 in the clutch ON state (see FIG. 2A), and in the clutch OFF state (see FIG. 3) in the direction of arrow S2 in the figure. This spring force can be applied to the clutch cam 52.

The above-mentioned return actuating piece 54 is arranged so as to be swingable about one guide shaft 56a. Specifically, the return operating piece 54 is arranged with the guide shaft 56a inserted through the elongated hole 54a formed in the return operating piece 54. Further, the return operating piece 54 is provided with an engaging portion 66 capable of engaging with the clutch return gear 37, and by swinging the return operating piece 54 around the guide shaft 56a, this engagement is performed. The joint portion 66 can be engaged with the clutch return gear 37.

Further, the clutch mechanism has a return actuating piece 5
A biasing spring 68 is provided to apply a desired engaging force to the engaging portion 66 of the returning operation piece 54 when the engaging portion 66 of No. 4 is engaged with the clutch returning gear 37. One end of the biasing spring 68 is locked to the return operating piece 54,
The other end is locked to a locking portion 70 formed on the flange 64 of the right frame 3b. And this biasing spring 6

6 is urged in a direction to engage with the clutch return gear 37.

Further, the clutch mechanism of the present embodiment is
By delaying the timing of engaging the return operation piece 54 with the clutch return gear 37 and increasing the spring force of the biasing spring 68 acting on the return operation piece 54, the clutch ON / OFF switching operation can be smoothly performed. A structure is provided to ensure the operation.

Specifically, the clutch cam 52 of the clutch mechanism has an operation restricting portion 72 having a cam shape inclined by a predetermined angle with respect to an arcuate locus with respect to the rotating shaft (spool shaft 8). Is provided.

The operation restricting portion 72 has a distance A between one end 72a and the center of rotation of the clutch cam 52 (center of the spool shaft 8) and the other end 72b and the center of rotation of the clutch cam 52 (spool shaft 8). Distance B) to the center of
It is formed so as to satisfy the relationship B.

Further, the return actuating piece 54 is formed with an abutting portion 74 capable of abutting against the operation regulating portion 72. In the clutch ON state (see FIG. 2A), the contact portion 74 is brought into contact with the one end 72a of the operation restricting portion 72 by the spring force of the biasing spring 68 acting on the return operation piece 54,
When switching from the clutch ON state to the clutch OFF state (see FIG. 2B), one end 72a of the operation restricting portion 72
Slides toward the other end 72b. Then, in the clutch OFF state (see FIG. 3), the contact portion 74 is
It is adapted to come off from the other end 72b of the operation restricting portion 72.

According to the relationship between the operation restricting portion 72 and the contact portion 74 of the return operating piece 54 as described above, first, in the clutch ON state (see FIG. 2A), the clutch cam 52 is The spring force of the hold spring 60 in the direction of the arrow S1 in the figure acts. At this time, the return operation piece 54 is maintained in a state in which the contact portion 74 thereof contacts the one end 72 a of the operation restricting portion 72 by the spring force of the biasing spring 68. In this case, the engaging portion 66 of the return operating piece 54 is in the disengaged state in which it is separated from the clutch returning gear 37 by a predetermined distance,
By rotating the handle 10 to rotate the handle shaft 10a, the spool 8a can be rotated in the fishing line winding direction.

Next, from the clutch ON state to the clutch O
When switching to the FF state (see FIG. 2B), if the clutch lever 50 is pressed in the direction of arrow T1, the clutch cam 52 rotates in the direction of arrow T2 around the spool shaft 8 in conjunction with this pressing operation. To do. At this time, the operation restricting portion 72 rotates the clutch cam 52 while maintaining a state in which the clutch cam 52 is inclined by a predetermined angle with respect to an arc-shaped locus with respect to the rotating shaft (spool shaft 8) of the clutch cam 52. Move with it. By the movement of the operation restricting portion 72 in this manner, the contact portion 74 of the return operation piece 54 that is in contact with the one end 72a of the operation restricting portion 72 is moved to the operation restricting portion 72.
From one end 72a toward the other end 72b.

The operation restricting portion 72 has a cam shape inclined by a predetermined angle so as to satisfy the relationship of A <B (see FIG. 2A) with respect to the rotation locus of the clutch cam 52. Therefore, when the contact portion 74 of the return actuating piece 54 slides from the one end 72a of the operation restricting portion 72 toward the other end 72b, the return actuating piece 54 causes the spring force of the biasing spring 68. And swings in the direction of arrow R1 (see FIG. 2B) around one guide shaft 56a. At this time, as the return actuating piece 54 swings in the direction of arrow R1, the engaging portion 66
Is further separated from the clutch return gear 37,
The biasing spring 68 extends in the direction of arrow G1 (see FIG. 2B). Then, the urging spring 68 expands in the direction of the arrow G1, so that the spring force of the urging spring 68 acting on the return operating piece 54 increases.

Then, in the clutch OFF state (see FIG. 3), the contact portion 74 of the return operating piece 54 is disengaged from the other end 72b of the operation restricting portion 72. At this time, the spring force of the urging spring 68 that has expanded in the direction of the arrow G1 and increased is released all at once, so that the urging spring 68 generates a strong spring force in the direction of the arrow G2 (see FIG. 3). This arrow G2
Due to the spring force in the direction, the return operating piece 54 swings in the direction of arrow R2 (see FIG. 3) about the one guide shaft 56a at once. At this time, the arrow R2 of the return actuating piece 54
With the swinging in the direction, the engaging portion 66 engages with the clutch return gear 37 vigorously and at high speed. As a result, the spool 8a is maintained in the free rotation state.

When returning from the clutch-off state to the clutch-on state again, one method is to push up the clutch lever 50 to return it to the state shown in FIG. 2 (a). The clutch lever 50 is shown in FIG.
When returning to the state of (a), the clutch cam 52
The spring force of the hold spring 60 in the direction of the arrow S1 in the figure causes the hold spring 60 to be returned to the state of FIG. At this time, due to the spring force of the urging spring 68, the contact portion 74 of the return actuating piece 54 is maintained in a state of abutting against the one end 72a of the operation restricting portion 72, and the engaging portion of the return actuating piece 54 is maintained. 66 is in a disengaged state separated from the clutch return gear 37.

Another method is to rotate the handle 10 in the fishing line winding direction. A return contact piece 76 is formed on the return operation piece 54 near the contact portion 74, while a return protrusion 78 is formed on the clutch cam 52 at a position facing the return contact piece 76. Has been done. When the handle 10 is rotated in the fishing line winding direction in the clutch OFF state (see FIG. 3), the clutch return gear 37 rotates in the direction of arrow H, and a pressing force is applied to the engaging portion 66 of the return operating piece 54. To do. The return operating piece 54, to which the pressing force is applied to the engaging portion 66, moves along the guide shaft 56a inserted into the elongated hole 54a, and the return contact piece 76 has the returning projection 78 of the clutch cam 52. Abut. Here, when the return protrusion 78 is pressed via the return contact piece 76 by further rotating the handle 10 to move the return operation piece 54, the clutch cam 52 will move to the arrow in FIG. 2B. It rotates in the direction opposite to T2. When this rotation amount exceeds a certain value, the spring force of the hold spring 60 in the direction of the arrow S1 in the figure acts on the clutch cam 52, and as a result, the clutch cam 52 is in the state shown in FIG. Be pulled back to. At this time, due to the spring force of the biasing spring 68,
The contact portion 74 of the return operating piece 54 has an operation restricting portion 72.
The engaging portion 66 of the return actuating piece 54 is kept in contact with the one end 72a of the above, and is in the disengaged state separated from the clutch returning gear 37.

As described above, according to the clutch mechanism of the present embodiment, when the clutch ON state is switched to the clutch OFF state, the engagement portion 66 of the return operating piece 54 is further separated from the clutch return gear 37. By
Clutch return gear 37 when the clutch is switched off
By making it possible to delay the timing of engaging the return operation piece 54 with, and at the same time, increasing the spring force of the biasing spring 68 acting on the return operation piece 54,
It is possible to increase the engaging force and the engaging speed of the engaging portion 66 of the return operating piece 54 with respect to the clutch returning gear 37.
Therefore, at the time of switching the clutch off, the engaging portion 66 of the return actuating piece 54 can be vigorously engaged with the clutch returning gear 37 at a predetermined timing and with a high engaging force. As a result, clutch ON / O
It is possible to realize a dual-bearing fishing reel equipped with a clutch mechanism capable of smoothly and reliably performing an FF switching operation.

Therefore, according to such a dual-bearing type fishing reel, the clutch O is used to confirm the free rotation performance of the spool 8a when the clutch is OFF, for example, at a store.
Even when the handle shaft 10a is rotated at a high speed in the N state and the clutch is disengaged at the same time or at a predetermined timing (clutch OFF operation), the return operating piece 54
It is possible to engage the engaging portion 66 of the clutch engaging gear 66 with the clutch returning gear 37 at a predetermined timing and with a high engaging force. As a result, it is possible to completely eliminate the inconvenience of being in the half-clutch state, so that the clutch can be smoothly and reliably disengaged.

Furthermore, for example, when the clutch lever 50 is erroneously pressed during a matching operation or a fishing line winding operation, in the present embodiment, the engaging portion 66 of the return operating piece 54 of the clutch mechanism is engaged with the clutch return gear. Since it can be maintained in a state of being further separated from 37, the engaging portion 66 of the returning operation piece 54 with respect to the rotating clutch returning gear 37.
It is possible to avoid a half-clutch state in which the vehicle contacts continuously or intermittently.

The present invention is not limited to the above-mentioned embodiment, but can be modified in various ways as follows.

As the supporting portion 62 for supporting the other end of the hold spring 60, for example, the supporting pin 6 as shown in FIG.
2'may be used. The support pin 62 'has a flange 64
The right frame 3b can be set through the insertion hole 64a formed in the right frame 3b.
A support groove 80 for supporting the insertion tip end side of the support pin 62 'inserted in the insertion hole 64a is formed in b.

According to this structure, when the support pin 62 'is set in the insertion hole 64a and the support groove 80,
Since the spring force of the hold spring 60 acts on the support pin 62 ′, the support pin 62 ′ is maintained in a state of being in surface contact with the insertion hole 64 a and the support groove 80. Hold spring 6
Since the spring force of 0 is relatively strong, the frictional force between the support pin 62 'and the insertion hole 64a and the support groove 80 is maintained high. Therefore, the support pin 62 'does not come out of the insertion hole 64a and the support groove 80.

As the locking portion 70 for locking the other end of the biasing spring 68, for example, a locking pin 70 'as shown in FIG. 4 (b) may be used. The locking pin 70 'has a flange 6
Through the insertion hole 64a 'formed in the right frame 3b
Can be set in the insertion hole 6
The insertion tip of the locking pin 70 'inserted through 4a' is in contact with the right frame 3b. Further, the locking pin 70 'is formed with a stepped portion 82 having a smaller diameter than the other portions.
Specifically, the stepped portion 82 is located between the flange 64 and the right frame 3b in a state where the locking pin 70 'is inserted into the insertion hole 64a' and the insertion tip is brought into contact with the right frame 3b. It is formed so as to be positioned in the area of. The other end of the biasing spring 68 is adapted to be locked to the step portion 82.

According to this structure, the locking pin 70 'is inserted into the insertion hole 64a' and the other end of the biasing spring 68 is provided with the stepped portion 82.
Since the other end of the urging spring 68 functions as a stopper in a state in which the locking pin 70 'is locked to the stepped portion 82,
It does not move vertically beyond the range of. Therefore, the locking pin 70 'does not come out of the insertion hole 64a'.

The support pin 62 'shown in FIG. 4 (a) is used.
Instead of the lock pin 7 shown in FIG.
You may use 0'as the support part 62 which supports the other end of the hold spring 60.

By the way, for example, at a store, a clutch OF is provided.
In order to confirm the free rotation performance of the spool 8a at the time of F, when the handle shaft 10a is rotated at a high speed in the clutch ON state, or when an operation of disengaging the clutch (clutch OFF operation) is performed at a predetermined timing. , The engagement timing of the engaging portion 66 of the return actuating piece 54 and the clutch return gear 37 rotating at a high speed in the direction of arrow H is deviated, and a half as shown in FIG. 5 and FIG. It may be in a clutch state.

In this case, by applying a pressing force from the clutch returning gear 37 to the engaging portion 66, the returning operating piece 54 is pushed back in the direction of arrow P, and the returning operating piece 54 is returned. A pressing force is applied to the return projection 78 of the clutch cam 52 by the contact piece 76. As a result, the clutch cam 52 moves in the arrow direction (that is, the clutch O
It will be pushed back to N state. Alternatively, the return contact piece 76 of the return operation piece 54 hits the return projection 78 of the clutch cam 52, and further rotation of the clutch cam 52 is restricted. As a result, the clutch cannot be released.

Therefore, in order to solve such a problem, in the clutch mechanism of this modification, a predetermined shape (for example, a substantially V shape, a substantially A cutout portion 84 having an inclined surface (tapered surface) having an arc shape is provided.

With such a structure, when the clutch mechanism is now in the half-clutch state, as shown in FIG. 6B, when the return actuating piece 54 is pushed back in the direction of arrow P, the clutch cam 52 returns. The projection 78 for insertion enters the notch 84 of the return actuating piece 54 and comes into sliding contact with the inclined surface (tapered surface) of the notch 84, thereby exerting a force in the direction of arrow Q on the return actuating piece 54. Is operated, the return operating piece 54 moves in the direction of arrow Q. That is, the return operation piece 54 moves in a direction in which the engaging portion 66 thereof is separated from the clutch return gear 37.

Then, as shown in FIG. 7A, when the return projection 78 of the clutch cam 52 is completely inserted into the notch 84 of the return operation piece 54, the return operation piece 54.
The engaging portion 66 of is completely separated from the clutch return gear 37. At this time, the urging spring 68 is slightly stretched in the direction of the arrow to increase its spring force.

From this state, the spring force of the urging spring 68 acts on the return actuating piece 54 again, so that the return actuating piece 54 has one of the guide shafts 5 similar to the above-described embodiment.
It swings at once in the direction of arrow R2 about 6a. At this time, as the return actuating piece 54 swings in the direction of arrow R2, the engaging portion 66 engages with the clutch return gear 37 vigorously and at high speed (see FIG. 7B).

According to the present invention, it is possible to eliminate the shift in the engagement timing between the engaging portion 66 of the return operating piece 54 and the clutch return gear 37 that rotates at a high speed in the direction of arrow H. It is possible to check the free rotation performance of the spool 8a when the clutch is OFF, without entering the clutch state.

The clutch mechanism according to the present invention can be applied to all types of reels, including the dual-bearing type fishing reel of the above-described embodiment.

[0059]

According to the present invention, by delaying the timing of engaging the return actuating piece with the return rotary member and increasing the spring force acting on the return actuating piece,
