Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drag mechanism for a double-bearing fishing reel.

[Conventional technology]

Conventionally, in the above-mentioned drag mechanism, one in which a drag member is attached to a master gear portion that transmits rotation of a handle to a spool shaft is known.

However, in the above drag mechanism and other conventional drag mechanisms, a star-shaped drag handle is attached to the lower part (base) of the handle arm, and the drag handle is screwed in or loosened by rotating the drag handle forward or backward. In particular, since the structure is designed to adjust the drag force, the handle arm gets in the way when operating the drag handle, making it difficult to adjust the drag force.
Further, there is a problem in that the adjustment cannot be made quickly in response to fish traffic, etc.

Therefore, the applicant has proposed a drag mechanism in which the drag handle is removed and a drag switch is provided in the side frame instead, and the drag force can be adjusted by switching the drag switch and using a handle for rotating the spool. It is now the first to apply.

The above-mentioned drag mechanism is effective in that it can solve the problems of the conventional mechanism described above, but the drag switch for engaging and disengaging the drag pawl on the drag latch and the reversal prevention pawl on the ratchet uses a dead point spring. and each switching position, that is, the OFF position.
Since the structure is such that each drag switch is biased and held in the ON position, when the drag switch is switched from the normal state to the drag adjustment state, or vice versa, it resists the elastic force of the dead point spring. Since the drag switch must be rotated to a position beyond its dead center, the switching operation tends to be unsmooth, and people often forget to switch the drag switch from the drag adjustment position to the normal position. If you turn the handle in this state, you may end up messing up the pre-adjusted drag force.

[Problem that the invention attempts to solve]

The present invention is an improved version of the drag mechanism described above, in which the drag switch is biased and held in the OFF position (normal position) by an anti-cam spring interposed in the anti-cam, so that the drag switch can be pushed and turned with a finger. After adjusting the drag force with the handle, the drag switch automatically returns to the OFF position, thereby avoiding the inconvenience caused by forgetting to switch the drag switch to the OFF position, and making the operation of the drag switch smooth and light. Its purpose was to make it possible to do so.

[Means for solving problems]

That is, in the present invention, a ratchet 7, a master gear 8, and a drag 9 are provided on the handle shaft from the base end side of the handle shaft 2 to the side plate 3 side in the hollow portion of the side frame 1 and the side plate 3. In a double-bearing reel drag mechanism configured such that the drag force can be adjusted by tightening and loosening a ratchet, a master gear, and a drag part, the tightening and loosening means is provided with a drag latch 10 on the handle shaft between the drag part and the side plate. When the drag latch is in a non-rotating state, the drag is tightened when the handle shaft is rotated, and the drag is loosened when the handle shaft is reversed. It is equipped with a rotational direction control means for engaging and disengaging,
A drag switch 1 concentrically grips a reversal prevention pawl 16, which is also provided with a disengagement member for disengaging the engagement with the ratchet by the pressing force of an anti-cam 18.
4 and 4 are respectively pivotally attached to the claw shaft 17. The drag switch has an operating portion 14c exposed outward from the side frame.
and the pressing portion 1 that comes into contact with the abutting piece 18a of the anti-cam.
4a and a pressing portion 14b.

Furthermore, a drag pawl 15 is provided coaxially with the drag switch and on the side plate side. The drag claw has a contact part 15b that contacts the pressing part 14b of the drag switch at one end, and a claw part 15a that engages and disengages from the drag latch at the other end, and the drag claw engages with the drag latch by a resilient means. When the drag switch operating section is manually operated in a direction that resists the repulsive force exerted by the anti-cam, the pressing section 14b of the drag switch separates from the abutting section, so that the repulsive force applied to the drag claw Accordingly, the hook is rotated, and the claw portion of the drag hook and the drag claw are configured to engage with each other. Further, the contact piece of the anti-cam is subjected to an elastic force by the resilient means in the direction of contacting the pressing portion 14a of the drag switch, and the drag switch is rotated counterclockwise by the contact piece of the anti-cam. The above-mentioned problem has been solved by constructing a structure in which the drag switch is pressed counterclockwise by the abutting part of the drag switch, and the claw part at the other end of the drag claw rotates to a position away from the drag chain, leaving the drag switch stationary. be.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. As shown in FIGS. 1 to 4, a handle shaft 2 is rotatably mounted between a pair of side frames 1 constituting the reel body. A handle 5 is removably fixed to the handle shaft 2 with a screw 6, located outside the side plate 3 which is supported and fixed to the outside of the side frame 1 by screws or the like.

In the handle shaft 2, in the intermediate portion between the side frame 1 and the side plate 3, a ratchet 7, a master gear 8, and a drag portion 9 are arranged in order from the base end side to the distal end side of the handle shaft 2. A drag chain 10 is provided.

The ratchet 7 is fixed to the handle shaft 2,
The master gear 8 is loosely fitted onto the handle shaft 2. In addition, the drag section 9 has a plurality of drag washers 9', 9''... and spring washers 9a, 9b mounted on the handle shaft 2 in order from the master gear 8 side, and these are attached to the drag chain 10 in FIG. By compressing the master gear 8 from the side to the master gear 8 side, the master gear 8 is crimped to the flange 4 of the handle shaft 2 via the washer 11 and the ratchet 7, thereby strengthening the coupling force between the handle shaft 2 and the master gear 8. The coupling force is weakened by releasing the compression, and therefore, the drag force is adjusted by adjusting the amount of compression to an appropriate value.

The drag latch 10 is attached to the handle shaft 2 so as to be slidable in the axial direction by a known cam means (not shown) or a screw means as shown. According to the illustrated screw means, a boss 10a fixed to the drag latch 10 is screwed onto the threaded portion 2a of the handle shaft 2, and an O-ring 12 is interposed between the boss 10a and the washer 9''. A retaining ring 13 is fixed to the handle shaft 2 to prevent it from coming off toward the handle 5 side.

Thus, by engaging the drag claw described later with the drag latch 10 to prevent its rotation, by rotating the handle shaft 2 forward or backward, the drag latch 10 spirals on the shaft, and the drag portion 9
The drag force can be arbitrarily adjusted by compressing or loosening the compression.

The master gear 8 is interlocked with a spool shaft (not shown) installed between the pair of side frames 1 through a gear transmission mechanism, and transmits the rotation of the handle 5 to the spool shaft.

In addition, in the illustrated example, the traverse cam shaft is connected to the handle shaft 2.
However, the present invention is not limited to the illustrated example, and has a structure in which a hollow shaft is rotatably mounted on a shaft (not shown) fixed to the side frame 1, and the hollow shaft is used as the handle shaft 2. In such a case, a ratchet 7, a master gear 8, a drag portion 9, and a drag latch 10 may be provided on the hollow handle shaft 2 in the same manner as described above.

Also, the above ratchet 7 and drag ratchet 10
A drag switch 14, a drag pawl 15, and a reverse prevention pawl 16 are provided near the outside of the frame 1 so as to be rotatable by a pawl shaft 17 that stands up from the side frame 1, and the drag switch 14 extends outward from the side frame 1. The drag pawl 15 and the anti-reverse pawl 16 are pivotally supported to be removably engaged with the drag latch 10 and the ratchet 7, respectively, and the anti-cam 1 is protruded.
8 is rotatably supported on a boss 19 projecting from the side frame 1.

The drag claw 15 has one end hooked to the drag switch 14 and the other end of the interposed drag claw spring 20 to elastically bias the claw portion 15a in the direction of engagement with the drag latch 10. be.

Further, the anti-cam 18 also has an interposed anti-cam spring 2 with one end hooked to a spring hook 21 of the side frame 1.
The other end of the anti-cam 18 is hooked and resiliently biased in the counterclockwise direction in FIGS. A pressing portion 14a protruding radially from the drag switch 14 and a pawl rivet 16a of the anti-reverse pawl 16 are abutted in the circumferential direction, respectively, so that the anti-cam spring 22 causes the drag switch 14 to be moved as shown in FIG. It is resiliently biased in the clockwise direction, and the drag switch 14 is held at the drag OFF position shown in FIG. 1, that is, in the normal state. The reversal prevention pawl 16 is provided with a pawl spring 16b holding the ratchet 7 in such a manner that it is not engaged when the ratchet 7 rotates in the normal direction, but can be engaged only when the ratchet 7 rotates in the reverse direction.

Further, a pressing portion 14b protruding radially from the drag switch 14 and an abutting piece 15b protruding radially from the drag claw 15 are butted against each other in the circumferential direction, thereby causing the drag claw 15 to is operated against the resiliency of the drag pawl spring 20, and is held in a position disengaged from the drag latch 10.

In the above configuration, under normal conditions when drag adjustment is not performed, the reverse rotation prevention pawl 16 does not engage with the latch 7 during normal rotation but engages with it during reverse rotation, while the drag pawl 15 does not engage with the drag latch 10 in the first rotation. It is maintained in the state shown in the figure.

When adjusting the drag, manually operate the operating portion 14c exposed from the side plate 1 of the drag switch 14 with your fingertips, rotate it counterclockwise in FIG. 1, and hold it. At this time, the pressing portion 14a of the drag switch 14 presses the abutment piece 18a, so the anti-cam 18 is rotated clockwise against the elastic force of the anti-cam spring 22. When the anti-cam 18 is rotated clockwise, the pressing portion 18b
presses the pawl rivet 16a in the circumferential direction, so the anti-reverse pawl 16 is rotated counterclockwise and disengaged from the ratchet 7.

Further, since the pressing portion 14b of the drag switch 14 also moves counterclockwise, the pressure on the abutment piece 15b of the drag claw 15 is released, and the drag claw 15
is rotated counterclockwise by the elastic force of the drag claw spring 20, and its claw portion 15a engages with the drag latch 10, resulting in the state shown in FIG.

In this state, the handle shaft 2 can be rotated forward or reverse by the handle 5, so if the handle shaft 2 is rotated forward or reverse as desired, the drag latch 10
Since rotation is prevented by the engagement of the drag pawl 15, the threaded portion 2a of the handle shaft 2 screws in the axial direction to compress the drag portion 9 or loosen the compression, thereby reducing the drag force. can be adjusted at will.

After adjusting the drag, to return to the normal state, that is, the fishing line winding state, when you release your finger pressing and holding the operating part 14c of the drag switch 14, the anti-cam 18 moves counterclockwise due to the elastic force of the anti-cam spring 22. Since it is rotated in the circumferential direction, the contact piece 1
Since the pressing part 14a is pressed at 8a, the drag switch 14 returns to rotation in the clockwise direction. At this time, the pressing part 14b presses the contact piece 15b, so the drag pawl 15 resists the elastic force of the drag pawl spring 20. Then, it is rotated clockwise, and the engagement with the drag latch 10 is released. At this time, the pressure on the pawl rivet 16a by the pressing portion 18b is released, so that the anti-reverse pawl 16 returns to its normal state as shown in FIG. 1 in which it can engage with the ratchet 7.

[Effect of the invention] As explained above, the drag mechanism of the double bearing reel according to the invention is configured, so the drag switch 14 is always elastically biased in one direction by the anti-cam spring 22 via the anti-cam 18. Therefore, after adjusting the drag force, simply by releasing the finger pressing and holding the drag switch 14, the anti-cam spring 22 will automatically return to the normal state, so the drag switch 14 should be reversed each time the drag is adjusted. Since there is no need to reset the drag mechanism, the operability of this type of drag mechanism can be improved, and the inconvenience caused by forgetting to switch the drag switch to the normal position after adjusting the drag can be avoided.

Furthermore, when the reversal prevention pawl 16 and the ratchet 7 are engaged with each other with tension on the fishing line, when the reversal prevention pawl 16 is released from the ratchet 7, in the conventional configuration, the reversal prevention pawl 16 is provided with a release part. The pressing force increases because the pressing force is increased because the pressing part 14a of the drag switch 14 presses the abutment piece 18a of the anti-cam 18, and this force is applied to the reversing prevention pawl 16 by the pressing part 18b which is closer to the rotation center of the anti-cam 18. Since it acts on the rivet 16a, it has the effect of being able to be released with a lighter force than when pressing the anti-reverse claw 16 directly due to the lever principle.
