Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag mechanism, and more particularly to a drag mechanism for a spinning reel which is mounted between a spool of a spinning reel and a spool shaft to apply a drag force to the spool.

[0002]

2. Description of the Related Art Generally, a spool of a spinning reel is equipped with a drag mechanism for applying a drag force to the spool. By installing a drag mechanism, it is difficult for the fishing line to break even if the load rises sharply when fish is caught in the tackle. The drag mechanism is provided between the spool shaft and the spool rotatably supported by the spool shaft, and is provided between the knob and the spool for screwing the spool shaft to adjust the drag force. And a friction plate that is non-rotatably provided on the shaft. The knob part
It is arranged so that it can contact the friction plate.
It is mounted in a circular recess formed in the front part of the spool.

In this type of drag mechanism, a drag force is applied to the spool by rotating the knob to press the friction plate against the spool. The drag force can be adjusted by adjusting the pressing force. It is known that the knob portion is provided with a sounding mechanism for generating a click sound when rotating. By providing the sounding mechanism, the operation feeling during drag operation can be improved. The knob portion includes a first member non-rotatably mounted on the spool shaft, a second member facing the first member and rotatable relative to the first member, and screwed to the spool shaft. It has a sounding mechanism which is arranged between the first member and the second member and produces a sound by relative rotation of both members. When the second member of the knob portion is rotated, the second member advances and retreats with respect to the spool shaft, and relatively rotates with respect to the first member, so that the sounding mechanism produces a sound.

[0004]

Generally, in a drag mechanism having a friction plate, when the friction plate gets wet with water, the frictional force fluctuates and the dragging force changes even if the knob portion is at the same position.
Therefore, it is known that a seal member is mounted in front of the friction plate between the knob and the circular recess of the spool to prevent water from entering the friction plate from the outer peripheral side of the knob. However, in the drag mechanism having the conventional sounding mechanism, since the knob portion is composed of the two members and the sounding mechanism, there is a gap between the two members of the knob portion. Therefore, even if a seal member is mounted between the knob portion and the spool, if water enters the inside of the knob portion through this gap, the intruded water penetrates the center portion of the knob portion along the spool shaft and the friction plate. There is a risk of invading the side.

An object of the present invention is to suppress the intrusion of liquid into the friction plate and make it difficult for the drag force to fluctuate.

[0006]

A drag mechanism for a spinning reel according to a first aspect of the present invention is a mechanism mounted between a spool of a spinning reel and a spool shaft for exerting a drag force on the spool, and a knob portion. A first friction plate, a first seal portion, and a second seal portion.
The knob part is a cylindrical part and a ring-shaped collar part with a larger diameter than the cylindrical part.
Is installed on the spool shaft so that it cannot rotate and can move axially.
And the first member that has been eclipsed, and in front of the first member in the spool axial direction.
On the outer circumference of the knob body and the knob body that are arranged side by side
The first member is fixed and the first member is housed so that it can rotate relative to the inside.
Between a first member and a second member having a bottomed cylindrical cover member that faces the first member, is rotatable relative to the first member, and is screwed onto the spool shaft; And a sounding mechanism that produces sound by relative rotation of both members, and is for manually adjusting the drag force. The first friction plate is a plate disposed between the knob portion and the spool and non-rotatably mounted on the spool shaft. The first seal portion is a seal portion that is mounted in front of the first friction plate so as to be capable of contacting the spool and the cylindrical portion of the first member, and prevents the liquid from flowing into the inside between them. The second seal part is the cover part
It is installed between the tip of the tubular part of the material and the knob body.
First to prevent liquid from flowing into the interior through the gap
The seal member, the rear end of the flange portion of the first member and the cover member.
It is installed between the bottom part and the liquid flows into the interior through the gap between them.
A second seal member for preventing
It is a seal portion for preventing liquid from flowing into the inside from between the member and the second member.

In this drag mechanism, when the second member of the knob portion screwed onto the spool shaft is turned, the knob portion advances and retreats with respect to the spool shaft, and the force pressing the first friction plate toward the spool side fluctuates, causing drag force. Can be adjusted. At this time, the first member and the second member relatively rotate, and the sounding mechanism produces a sound. Further, even if the knob portion gets wet with water, for example, the first and second seal portions allow the liquid to enter the inside through the gap between the outer peripheral side of the knob portion and the spool and between the first member and the second member. As a result, the liquid can be prevented from entering the first friction plate through the knob portion. Therefore, if the knobs are at the same drag setting position, the drag force is unlikely to change. Well
Also, the gap between the cover member and the knob body and the first member
Are sealed by the first and second sealing members, respectively.
Therefore, even if the cover member covers the first member,
The liquid does not enter the inside between the body and the first member.

A drag mechanism for a spinning reel according to a second aspect of the present invention is the mechanism according to the first aspect, further comprising a second friction plate which is non-rotatably mounted on the spool and is arranged so as to face the first friction plate. In this case, since the drag force is generated by the plurality of friction plates, the drag force can be finely adjusted. A drag mechanism for a spinning reel according to a third aspect of the present invention is the mechanism according to the first or second aspect of the invention, wherein the first seal member is O.
The second seal member is a washer-shaped seal ring.

A spinning reel drag machine according to a fourth aspect of the present invention.
The structure is the mechanism according to any one of Inventions 1 to 3,

When water enters from this gap, even if the seal plate 71 is provided, water enters the friction part 62 through the gap between the first member 63 and the spool shaft 15, wets the friction part 62, and changes the drag force. I have something to do.

As shown in FIGS. 4 and 5, the sounding mechanism 65 is retractably housed in a sound output hole 75 formed in the cylindrical portion 63a of the first member 63 and a recess 67b formed in the knob body 67.

The outer diameter D1 is, for example, 1.2 mm, and the outer diameter D2 is 3
mm. Outer diameter D1 is 20% to 50% of outer diameter D2
It is desirable to be in the range of. In this way, the contact portion 76a
By reducing the outer diameter of the sound output holes 75, the intervals of the sound output holes 75 can be narrowed and the number thereof can be increased. Moreover, the mass of the sound producing pin 76 itself does not become so small as compared with the case where the spring receiving portion 76b and the contact portion 76a have the same diameter. Therefore, inertia is maintained and a crisp click sound is generated. Moreover, since it is not necessary to reduce the wire diameter of the sound producing spring 77, the spring force can be maintained high and the sharpness can be improved.

As shown in FIG. 2, the friction portion 62 includes a first disk 81 that contacts the first member 63 and a first disk 8.
The second disk 82 that contacts the first member with the felt member interposed therebetween.
And a drag sounding mechanism 83 that comes into contact with the second disk 82 with the felt member sandwiched therebetween. First disk 81
The inner peripheral portion of which is locked to the spool shaft 15,
Rotate with. The outer periphery of the second disk 82 is locked to the spool 4 and rotates together with the spool 4. The drag sounding mechanism 83 sounds when the spool shaft 15 and the spool 4 rotate relative to each other, that is, when the dragging operation is performed.

[Reel Operation and Operation] Before fishing, the drag force is adjusted according to the size and type of fish. To adjust the drag force, turn the knob body 67. When the knob body 67 is rotated clockwise, for example, the coil spring 70 is screwed by the nut 69 screwed onto the spool shaft 15.
The first member 63 is pressed toward the friction portion 62 side via. This increases the drag force. At this time, the first member 6
Due to the relative rotation between the third member 64 and the second member 64, the sound producing pin 76 repeatedly collides with the sound producing hole 75 at a predetermined interval to generate a light clicking sound with good crispness.

At the time of casting, the bail arm 44 is reversed to the line releasing posture. As a result, the first bail support member 40 and the second bail support member 42 swing. In this state, cast the fishing rod while hooking the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously due to the weight of the tackle. When the handle 1 is rotated in the yarn winding direction in this state, the rotor 3 is rotated in the yarn winding direction by the rotor driving mechanism 5, and the bail arm 44 is rotated.
Is returned to the line winding position by the bale reversing mechanism 46, and the fishing line is wound around the spool 4.

When fishing, the reel may be wet due to waves or the like. Also in this case,
Since the seal plate 71, the seal ring 72, and the O ring 73 are attached to the drag mechanism 60, water is unlikely to enter the friction portion 62. Therefore, once the drag force is adjusted, the drag force rarely changes due to water wetting. [Other Embodiments] (a) In the above embodiment, the first member 63 and the second member 64 are provided.
Although and are arranged to face each other in the axial direction, they may be arranged to face each other in the radial direction. In this case, the sounding mechanism may be arranged along the radial direction.

(B) In the above embodiment, the seal ring and the O-ring prevent water from entering through the gap between the first member and the second member. However, the seal member is directly attached to the facing surface of both members. May be. In this case, the number of seal members can be reduced.

[0031]

According to the present invention, even if the knob portion is wet with water, for example, the first and second seal portions cause the gap between the outer peripheral side of the knob portion and the spool and the gap between the first member and the second member. Since the liquid is prevented from entering the inside through the gaps, it is possible to suppress the liquid from entering the first friction plate from the knob portion. Therefore, if the knobs are at the same drag setting position, the drag force is unlikely to change.
