Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drag mechanism, and more particularly, to a drag mechanism of a spinning reel that is mounted between a spool of a spinning reel and a spool shaft to apply a drag force to the spool.
[0002]
[Prior art]
Generally, a drag mechanism for applying a drag force to a spool is mounted on a front drag type spool of a spinning reel. By installing the drag mechanism, it becomes difficult for the fishing line to break even when the load suddenly increases when a fish is applied to the device. A drag mechanism is provided between the spool shaft and the spool rotatably supported by the spool shaft, and a knob for screwing to the spool shaft to adjust a drag force; and a spool between the knob and the spool. A friction portion provided non-rotatably on the shaft. The knob portion is arranged so as to be able to contact the friction portion, and the friction portion is usually mounted in a circular recess formed in the front portion of the spool.
[0003]
In this type of drag mechanism, a drag force is applied to the spool by turning the knob and pressing the friction portion toward the spool. Drag force can be adjusted by adjusting this pressing force. There is a known knob provided with a sound generating mechanism for generating a click sound when rotated. By providing the sound generating mechanism, the operation feeling at the time of the drag operation can be improved. The knob portion includes a first member non-rotatably mounted on the spool shaft, and a second member axially arranged in parallel with the first member and rotatably provided with the first member and screwed to the spool shaft. It has a member and a sound generating mechanism disposed between the first member and the second member to generate sound by the relative rotation of both members. When the second member of the knob is turned, the second member advances and retreats with respect to the spool shaft, and rotates relative to the first member, so that the sound generating mechanism emits sound.
[0004]
Generally, in a drag mechanism having a friction portion, when the friction portion gets wet with water, the friction force changes and the drag force changes even when the knob is located at the same position. In view of this, there is conventionally known a device in which a sealing member is mounted between the knob and the circular concave portion of the spool in front of the friction portion to prevent water from entering the friction plate from the outer peripheral side of the knob (for example, Patent Document 1).
[0005]
In the drag mechanism having the conventional sound generating mechanism, a gap is generated between the two members of the knob because the sound generating mechanism includes the two members having the knobs arranged side by side. Therefore, even if the seal member is mounted between the knob and the spool, a gap remains between the two members. When water intrudes into the knob portion from this gap, there is a possibility that the intruded water may enter the friction portion along the spool shaft penetrating the center portion of the knob portion. Therefore, the gap between the two members of the knob is also sealed by the two seal members.
[0006]

See JP-A-11-196729 (page 4, right column, see FIG. 2)
[0007]
[Problems to be solved by the invention]
In the above-described conventional configuration having a sound generating mechanism, a seal member for sealing a gap between the knob and the spool in front of the friction portion of the drag mechanism, and two seals for sealing a gap between two members arranged side by side with the knob. Water is prevented from entering the friction portion by a total of three seal members. For this reason, the seal structure for waterproofing the friction portion becomes complicated.
[0008]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a drag mechanism for a spinning reel that can prevent liquid from entering a friction portion with a simple seal structure.
[0009]
[Means for Solving the Problems]
A drag mechanism for a spinning reel according to a first aspect of the present invention is a mechanism that is mounted between a spool of the spinning reel and a spool shaft to apply a drag force to the spool, and includes a knob, a friction part, and a seal member. Have. The knob is provided with a first member having a flange portion and being provided on the spool shaft so as to be non-rotatable and movable in the axial direction, and a knob provided on the spool shaft so as to face the first member and to be rotatable relative to the first member. A second member protruding in a cylindrical shape toward the first member so as to cover the flange portion, a connecting member for connecting the first member and the second member in an axially immovable and rotatable manner, A sound generating mechanism is provided between the first member and the second member and emits sound by the relative rotation of the two members, and is used for adjusting the drag force by hand. The friction portion is disposed between the knob and the spool, and is pressed toward the spool by the knob. The seal member is disposed between the spool and the first member in front of the friction portion, and is a member that simultaneously seals a gap between the spool and the first member and a gap between the first member and the second member.
[0010]
In this drag mechanism, when the second member of the knob portion screwed to the spool shaft is turned, at least a part of the knob portion advances and retreats with respect to the spool shaft, and the force for pressing the first friction plate toward the spool fluctuates. The power can be adjusted. At this time, the first member and the second member rotate relatively, and the sound generating mechanism emits sound. Further, even if the knob is wet, for example, the seal member prevents the liquid from entering the inside from the gap between the outer peripheral side of the knob and the spool and the gap between the first member and the second member. Therefore, intrusion of the liquid from the knob portion to the friction portion can be suppressed. Here, since the second member of the knob portion projects toward the first member so as to cover the flange portion of the first member, for example, the sealing member disposed between the spool and the first member may be protruded. By also contacting the portions, the gap between the spool and the first member and the gap between the first member and the second member can be simultaneously sealed. For this reason, it is possible to prevent the liquid from entering the friction portion with a simple seal structure.

In this case, since the seal member does not have a hard member made of metal or the like for backup, the diameter of the seal member is increased like a general O-ring to slide the outer peripheral surface of the first member. Can be easily installed in the annular groove. For this reason, a fixing member for fixing the seal member, such as a snap ring, and a space for mounting the fixing member are not required, and the space in the axial direction is compact.
[0012]
A drag mechanism for a spinning reel according to a third aspect of the present invention is the drag mechanism according to the first or second aspect, wherein the seal member has an annular mounting portion mounted on the first member, and extends from the mounting portion toward the inner peripheral surface of the spool. A first seal portion extending from the mounting portion to a projecting portion of the second member; In this case, the gap between the spool and the first member is sealed by the first seal portion extending from the annular mounting portion toward the inner peripheral surface of the spool, and the flange portion of the second member is sealed from the annular mounting portion. The gap between the first member and the second member is sealed by the second seal portion extending toward the projecting portion to be covered.
[0013]
A drag mechanism for a spinning reel according to a fourth aspect is the mechanism according to the third aspect, wherein the first seal portion has a lip portion having a tapered cross section. In this case, since the lip portion having the tapered cross section is formed at the contact portion with the spool, the contact area with the spool is reduced, and the first member that cannot rotate with respect to the spool shaft and the lip portion with respect to the spool shaft rotate. In this case, an increase in rotational resistance when the spool rotates relatively to the rotating spool can be suppressed.
[0014]
A drag mechanism for a spinning reel according to a fifth aspect of the present invention is the mechanism according to any one of the first to fourth aspects, wherein the friction portion is non-rotatably mounted on the spool and a first friction plate non-rotatably mounted on the spool shaft. A second friction plate disposed opposite to 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.
[0015]
A drag mechanism for a spinning reel according to a sixth aspect of the invention is the mechanism according to any one of the first to fifth aspects, wherein the second member has an operation portion on a front surface, and the first member has an operation portion on a rear end to cover a flange portion. A knob portion main body rotatably mounted on the spool shaft, a knob portion main body rotatably mounted on the spool shaft and having a cover portion protruding in a cylindrical shape and having a rear end surface in contact with the seal member; And a spring member disposed between the nut portion and the first member. In this case, when the operating portion of the knob main body is turned, the nut portion rotates together with the knob main body, the spring member expands and contracts, and the force of the first member pressing the friction portion changes, and the drag force changes. At this time, since the rear end surface of the cover portion is in contact with the seal member, it is difficult for liquid to penetrate through the gap between the cover portion and the flange portion.
[0016]
A drag mechanism for a spinning reel according to a seventh aspect of the invention is the drag mechanism according to the sixth aspect, wherein a locking portion is formed on an inner peripheral surface of the cover portion, and the connecting member is locked by the locking portion to prevent the flange portion from coming off. It is a member formed by bending a wire having elasticity.

A contact portion that comes in contact with the cover portion, and is a member that can be attached from the rear end side of the cover portion to prevent the flange portion from coming off. In this case, the flange of the first member is housed in the cover from the rear end of the second member, and in this state, the connecting member is housed in the cover while being compressed from the rear end so as to pass through the cover. Then, the engaging portion of the connecting member is positioned in the locking groove formed on the inner peripheral surface of the cover portion to release the compressed state. Then, since the locking groove is formed only up to the near side from the rear end face of the cover portion, a step is generated between the locking groove and the rear end face, the engaging portion is locked to the step, and the connecting member is connected to the second member. Cannot move to the rear end side. In this state, the contact portion comes into contact with the flange of the first member, and the first member cannot move to the rear end side. Therefore, the first component is prevented from coming off. Since the locking groove is formed from the front side toward the rear end face, it can be formed by a mold at the time of molding. Here, since the structure for locking the connecting member can be formed by molding, the locking structure for the connecting member can be realized without machining, and the processing cost can be reduced.

A large number of hemispherical sound output holes 65c are formed side by side in the circumferential direction on the front end surface of the flange portion 65a. An oval locking hole 65d is formed in the inner peripheral portion of the cylindrical portion 65b so as to lock the spool shaft 15 so as not to rotate. An annular groove 65e for mounting the seal member 63 is formed on the outer peripheral surface of the cylindrical portion 65b. The rear end face of the cylindrical portion 65b contacts the drag disk 62a of the friction portion 62.
[0030]
The second member 66 is provided to be rotatable relative to the first member 65 so as to face the first member, and is screwed to the spool shaft 15. The second member 66 is formed in a cylindrical shape toward the first member 65 so as to cover the flange 65 a.

[0032]
The operation unit 70a is a projection formed in a substantially trapezoidal shape along the diameter. The cover portion 70b projects cylindrically toward the first member 65 so as to cover the flange portion 65a, and a rear end surface thereof is in contact with the seal member 63. The locking groove 70c is formed in a semicircular shape on the inner peripheral surface of the cover portion 70b by a round hole formed from the operation portion 70a, and is formed from the rear end of the inner peripheral surface of the cover portion 70b to the near side. . The connecting member 67 is locked to the formation end 70f of the locking groove 70c. The round hole for forming the locking groove 70c is hidden by a seal 70d attached to the front surface of the knob main body 70. In this way, by sealing the seal 70d and closing the round hole, even if the locking groove 70c is formed by the round hole for molding, it becomes difficult for foreign substances such as water to enter the inside of the knob main body 70.
[0033]
In the center of the knob main body 70, a nut mounting portion 70e is formed in which a square nut portion 72 is mounted so as to be non-rotatable and axially movable. On the rear surface of the knob main body 70, a mounting hole 70g for accommodating the second sound generation mechanism 68 is formed. The nut portion 72 is screwed into a male screw portion 15a formed at the tip of the spool shaft 15. The spring member 73 is mounted between the nut portion 72 and the first member 65 in a compressed state.

And a coil spring 78 that urges toward the sound output hole 65c. A large number of sound output holes 65c are formed at positions that can face the mounting holes 70g at intervals in the circumferential direction. The sound output pin 77 is a pin having a large diameter at the center portion, a small diameter at the front and rear ends, and a rounded hemisphere at the front end. When the knob main body 70 and the first member 65 rotate relative to each other at the time of drag operation, sound is output. The collision with the outlet hole 65c is repeatedly sounded.
[0036]
As shown in FIG. 4, the drag disk 62 a of the friction portion 62 is a metal disk member that is in contact with the first member 65 and cannot rotate with respect to the spool shaft 15. The drag disk 62b is a disc member made of, for example, felt and rotatable with respect to the spool 4 and the spool shaft 15. The drag disk 62c is a metal disk member that cannot rotate with respect to the spool 4. The drag disk 62d is a disc member made of, for example, felt and rotatable with respect to the spool 4 and the spool shaft 15. At the center of the drag disk 62a, a long groove-shaped locking hole 62e is formed to engage with the chamfered portion 15b formed parallel to each other at the tip of the spool shaft 15. A pair of lugs 62f projecting outward in the radial direction are formed on the outer peripheral surface of the drag disk 62c. The lugs 62f extend axially along the inner peripheral surface of the cylindrical portion 4d of the bobbin trunk 4a. It is locked in the locking groove 4f formed. As a result, the drag disk 62c cannot rotate with respect to the spool 4.
[0037]
A retaining spring 75 is in contact with the front surface of the drag disk 62a. The retaining spring 75 has a pentagonal shape different from the connecting member 67, and each corner 75a projects radially outward from the drag disk 62a and is formed on the inner peripheral surface of the cylindrical portion 4d of the bobbin trunk 4a. The contact portion 75b is in contact with the drag disk 62a, and the drag disks 62a to 62d are prevented from coming off. As a result, the drag disks 62a to 62d do not fall off even when the knob 61 is removed from the spool shaft 15.
[0038]
The seal member 63 includes a mounting portion 63a mounted on the first member 65 in the annular groove 65e, a first seal portion 63b extending from the mounting portion 63a toward the inner peripheral surface of the spool ring collar 55, and a first seal portion 63a extending from the mounting portion 63a. A second seal portion 63c extending toward a protruding portion of the two members 66 (the rear end surface of the cover portion 70b). The mounting portion 63a is a ring-shaped portion having an inner diameter that is locked in the annular groove 65e having a rectangular cross section. The first seal portion 63 b seals a gap between the spool 4 and the first member 65, and has a lip portion having a tapered cross section that comes into contact with the inner peripheral surface of the inner cylindrical portion 55 b of the spool ring collar 55 of the spool 4 at the tip. 63d. Since the lip portion 63d having the tapered cross section is formed at the contact portion with the spool 4, the contact area with the spool ring collar 55 is reduced, and the first member 65 that cannot rotate with respect to the spool shaft 15 is formed. An increase in rotational resistance when the spool 4 that rotates with respect to the spool shaft 15 rotates relatively can be suppressed. The second seal portion 63c seals a gap between the first member 65 and the second member of the knob 61, and has a rectangular cross section that contacts the rear end surface of the cover 70b.
[0039]
Here, since the second member 66 of the knob 61 projects toward the first member 65 so as to cover the flange 65a of the first member 65, the second member 66 is disposed between the spool 4 and the first member 65. The gap between the spool 4 and the first member 65 and the gap between the first member 65 and the second member 66 can be simultaneously sealed by bringing the seal member 63 into contact with the projecting portion. Therefore, it is possible to prevent the liquid from entering the friction portion 62 with a simple seal structure.
[0040]
The first sounding mechanism 64 is a mechanism that emits sound when the spool shaft 15 and the spool 4 rotate relative to each other due to the operation of the drag. As shown in FIG. 3, the first sound generating mechanism 64 collides with the sound output member 81 non-rotatably mounted on the spool shaft 15 and swingably mounted on the back surface of the support 4e of the spool 4. And a spring member (not shown) for urging the claw member 82 toward the sounding member 81.
[0041]
[Reel operation and operation]
Adjust the drag power according to the size and type of fish before fishing. To adjust the drag force, the knob body 70 is turned. When the knob main body 70 is turned, for example, clockwise, the first member 65 is pressed toward the friction portion 62 via the spring member 73 by the nut portion 72 screwed to the spool shaft 15. This increases the drag force. At this time, due to the relative rotation of the first member 65 and the second member 66, the sounding pin 77 repeatedly collides with the sounding hole 65c at a predetermined interval, and generates a light click sound with good crispness.
[0042]
At the time of casting, the bail arm 44 is inverted to the line releasing posture. Thereby, the first bail support member 40 and the second bail support member 42 swing. In this state, the fishing rod is cast while catching the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously by the weight of the device. When the handle 1 is rotated in the line winding direction in this state, the rotor 3 is rotated in the line winding direction by the rotor driving mechanism 5, the bail arm 44 is returned to the line winding position by the bail reversing mechanism (not shown), and the fishing line is returned. It is wound around the spool 4.
[0043]
When fishing, the reel may get wet due to the waves hitting the reel. Also in this case, since the seal member 63 is mounted on the drag mechanism 60, the gap between the spool 4 and the first member 65 and the gap between the first member 65 and the second member 66 are sealed. For this reason, it is difficult for water to enter the friction portion 62 from the gaps. For this reason, once the drag force is adjusted, the drag force is less likely to fluctuate due to water wetting.

[Other embodiments]
(A) In the above embodiment, the two gaps are sealed by a sealing member made of an elastic body, but a hard ring-shaped or tubular reinforcing member for backup may be interposed inside the elastic body. In this case, since the seal member cannot be mounted in the annular groove or the like, a separate fixing member such as a retaining ring is separately required.
[0045]
(B) In the above embodiment, the seal member is mounted on the first member, but the seal member may be mounted on the spool side. In this case, when the knob 61 is loosened and the drag mechanism 60 is deactivated, the knob 61 moves forward in the spool axial direction, so that the second seal portion 63c of the seal member 63 separates from the rear end surface of the second member 66. I do. However, in the normal drag operation state, the second seal portion 63c can contact the rear end face of the second member 66 to seal the gap between the two members 65, 66.

【The invention's effect】
According to the present invention, since the second member of the knob portion projects toward the first member so as to cover the flange of the first member, for example, a seal member disposed between the spool and the first member The gap between the spool and the first member and the gap between the first member and the second member can be simultaneously sealed by contacting the first member with the projecting portion. For this reason, it is possible to prevent the liquid from entering the friction portion with a simple seal structure.
