Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drag mechanism, and more particularly to a spinning reel drag mechanism that is mounted between a spool of a spinning reel and a spool shaft and applies a drag force to the spool.
[0002]
[Prior art]
In general, a front drag type spool of a spinning reel is equipped with a drag mechanism for applying a drag force to the spool. By installing the drag mechanism, even if the load suddenly rises when a fish is applied to the mechanism, the fishing line is hard to break. The drag mechanism is provided between the spool shaft and a spool rotatably supported by the spool shaft, and is configured to be engaged with the spool shaft to adjust the drag force, and the spool between the knob portion and the spool. And a friction part provided on the shaft so as not to rotate. The knob portion is disposed so as to be in contact with 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 portion and pressing the friction portion toward the spool. The drag force can be adjusted by adjusting the pressing force. In this knob part, a sound generation mechanism that generates a click sound when rotating is known. By providing the sound generation mechanism, the operation feeling at the time of drag operation can be improved. The knob portion includes a first member that is non-rotatably mounted on the spool shaft, and a second member that is provided in parallel with the first member in the axial direction and is rotatable relative to the first member and is screwed onto the spool shaft. A member and a sounding mechanism that is disposed between the first member and the second member and generates sound by relative rotation of both members. When the second member of the knob portion is turned, the second member advances and retreats with respect to the spool shaft, and rotates relative to the first member to generate sound.
[0004]
In general, in a drag mechanism having a friction part, when the friction part gets wet, the frictional force fluctuates and the drag force changes even when the knob part is in the same position. In view of this, there is conventionally known a structure in which a seal member is mounted between the knob portion and the circular concave portion of the spool in front of the friction portion so that water does not enter the friction plate from the outer peripheral side of the knob portion (for example, Patent Document 1).
[0005]
In the drag mechanism having the conventional sound generation mechanism, a gap is formed between the two members of the knob portion because it is composed of two members having the knob portion arranged in parallel and the sound generation mechanism. Therefore, even if the seal member is mounted between the knob portion and the spool, a gap between the two members remains. If water enters the inside of the knob portion from this gap, the intruded water may enter the friction portion side along the spool shaft that passes through the center portion of the knob portion. Therefore, the gap between the two members of the knob portion is also sealed with two seal members.
[0006]
[Patent Document 1]
See JP-A-11-196729 (see right column on page 4, FIG. 2).
[0007]
[Problems to be solved by the invention]
In the conventional configuration having the sound generation mechanism, a seal member that seals the gap between the knob portion and the spool in front of the friction portion of the drag mechanism, and two seals that seal the gap between the two members arranged side by side of the knob portion A total of three sealing members together with the members prevent water from entering the friction part. For this reason, the seal structure for waterproofing the friction part becomes complicated.
[0008]
SUMMARY OF THE INVENTION An object of the present invention is to make it possible to prevent liquid from entering a friction portion with a simple seal structure in a spinning reel drag mechanism.
[0009]
[Means for Solving the Problems]
A spinning reel drag mechanism according to a first aspect of the present invention is a mechanism that is mounted between a spinning reel spool and a spool shaft and applies a drag force to the spool, and includes a knob portion, a friction portion, and a seal member. I have. The knob portion has a collar portion and is provided with a first member that is non-rotatable and axially movable on the spool shaft, and is rotatably provided relative to the first member so as to face the first member, and is screwed onto the spool shaft. And a second member that protrudes in a cylindrical shape toward the first member so as to cover the flange, and the first member and the second member that are provided inside the second member are not movable in the axial direction and are rotatable. And a sound generating mechanism that is arranged between the first member and the second member and generates sound by relative rotation of both members, and is used for adjusting the drag force by hand. The friction portion is disposed between the knob portion and the spool and is pressed toward the spool by the knob portion. The seal member is a member that is disposed between the spool and the first member in front of the friction portion, and seals the gap between the spool and the first member and the gap between the first member and the second member at the same time. The first member has an annular groove on the outer peripheral surface. The seal member is made of a synthetic resin having elasticity attached to the annular groove, and includes an annular attachment portion attached to the annular groove, a first seal portion extending from the attachment portion toward the inner peripheral surface of the spool, and attachment A second seal portion extending from the portion toward the protruding portion of 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 moves forward and backward with respect to the spool shaft, and the force for pressing the first friction plate toward the spool fluctuates. You can adjust the power. At this time, the first member and the second member rotate relative to each other and the sound generation mechanism generates a sound. In addition, even if the knob is wet, for example, the seal member prevents liquid from entering from the gap between the outer periphery of the knob and the spool and the gap between the first member and the second member. Therefore, it is possible to suppress liquid from entering the friction portion from the knob portion. Here, since the second member of the knob portion protrudes toward the first member so as to cover the flange portion of the first member, for example, the seal member disposed between the spool and the first member is protruded. By contacting the portion, the gap between the spool and the first member and the gap between the first member and the second member can be sealed simultaneously. Therefore, it is possible to prevent the liquid from entering the friction portion with a simple seal structure.
[0011]
Further, since the seal member does not have a hard member such as a metal for backup, the diameter of the seal member is increased and the outer peripheral surface of the cylindrical portion of the first member is slid like a general O-ring. Can be easily installed in the annular groove. For this reason, a fixing member such as a snap ring for fixing the seal member and a space for mounting it are unnecessary, and the axial space is also compact.
[0012]
Furthermore, the first seal portion extending from the annular mounting portion toward the inner peripheral surface of the spool seals the gap between the spool and the first member, and the protruding portion covers the flange portion of the second member 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 front.
[0013]
Drag mechanism of a spinning reel according to a second aspect is the mechanism according to the invention 1, the first seal portion includes a lip portion of tapered cross-section. In this case, since the lip portion having a 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 rotates with respect to the spool shaft. An increase in rotational resistance when the spool that rotates is relatively rotated can be suppressed.
[0014]
The spinning reel drag mechanism according to a third aspect of the present invention is the mechanism according to the first or second aspect , wherein the friction portion includes a first friction plate that is non-rotatably mounted on the spool shaft, and a first friction plate that is non-rotatably mounted on the spool. And a second friction plate disposed to face the plate. In this case, since the drag force is generated by the plurality of friction plates, the drag force can be finely adjusted.
[0015]
The spinning reel drag mechanism according to a fourth aspect of the present invention is the mechanism according to any one of the first to third aspects, wherein the second member has an operation portion on the front surface and the first member so as to cover the collar portion at the rear end. A knob portion body that protrudes in a cylindrical shape and has a rear end surface that comes into contact with the seal member, and is rotatably attached to the spool shaft, and is attached to the knob body in a non-rotatable and axially movable manner. And a spring member disposed between the nut part and the first member. In this case, when the operation 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 with which the first member presses the friction portion is changed to change the drag force. At this time, since the rear end surface of the cover portion is in contact with the seal member, it is difficult for the liquid to enter from the gap between the cover portion and the flange portion.
[0016]
The spinning reel drag mechanism according to a fifth aspect of the present invention is the mechanism according to the fourth aspect, wherein a locking portion is formed on the inner peripheral surface of the cover portion, and the connecting member is locked to the locking portion to prevent the collar portion from coming off. It is a member formed by bending a wire having elasticity.
[0017]
A spinning reel drag mechanism according to a sixth aspect of the present invention is the mechanism according to the fifth aspect , wherein the locking portion is spaced from the front surface through the inner peripheral surface of the cover portion to the front side of the rear end surface in the circumferential direction, and the spool shaft. A plurality of engaging grooves formed along the direction, and the connecting member includes a plurality of engaging portions that are engaged with the plurality of engaging grooves, and an integrally formed engaging portion from the rear end side to the flange portion. It is a member which has a contact part which contacts and can be installed from the rear end side of the cover part in order to prevent the collar part from coming off. In this case, the collar portion of the first member is stored in the cover portion from the rear end side of the second member, and in this state, the connecting member is stored in the cover portion while being compressed so as to pass through the cover portion from the rear end side. 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 to the near side from the rear end surface of the cover portion, a step is formed between the rear end surface, the engaging portion is locked at the step, and the connecting member is the second member. It becomes impossible to move to the rear end side. Further, in this state, the contact portion comes into contact with the flange portion of the first member, and the first member cannot move to the rear end side. For this reason, the first component is prevented from coming off. Since this 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 of the connecting member can be realized without machining, and the processing cost can be reduced.

As shown in FIG. 2, the spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3, and is attached to the tip of the spool shaft 15 via a drag mechanism 60. . As shown in FIG. 3, the spool 4 has a fishing line wound around its outer periphery, for example, an aluminum alloy bobbin trunk 4a, a skirt 4b integrally formed at the rear of the bobbin trunk 4a, and a bobbin trunk 4a. And a front flange portion 4c made of, for example, an aluminum alloy. The bobbin trunk 4 a is a cylindrical member, and the outer peripheral surface is constituted by a peripheral surface parallel to the spool shaft 15. The bobbin trunk 4a has a cylindrical portion 4d around which the fishing line is wound and a support portion 4e provided on the inner peripheral surface of the cylindrical portion 4d, and the support portion 4e is rotatable and restricted from moving backward. In this state, the spool shaft 15 is mounted. The front flange portion 4c is formed by bending the outer peripheral edge of a washer-like aluminum alloy sheet member forward by, for example, curling. The front flange portion 4c is fixed to the front surface of the bobbin trunk 4a by, for example, four screws 90 and is fixed to the front surface of the bobbin trunk 4a by, for example, a spool ring collar 55 screwed to, for example, four screws 91.

It has the connection part 55c which connects the part 55a and the inner cylinder part 55b. Two types of screws 90 and 91 are alternately arranged at equal intervals in the connecting portion 55c.
[0030]
[Configuration of drag mechanism]
As shown in FIGS. 3 and 4, the drag mechanism 60 is a mechanism for braking the rotation of the spool 4 in the yarn unwinding direction and applying a drag force to the spool 4. The drag mechanism 60 includes a knob portion 61 for manually adjusting the drag force, a friction portion 62 having, for example, four drag disks 62 a to 62 d pressed against the spool 4 by the knob portion 61, and a friction portion 62. A seal member 63 for preventing liquid from entering the first sound generation mechanism 64 and a first sound generation mechanism 64 that generates sound when the drag is operated.
[0031]
As shown in FIGS. 5 to 7, the knob portion 61 includes a first member 65, a second member 66 disposed so as to face the first member 65, and both members 65, 66 being relatively rotatable and axially movable. It has the connection member 67 connected so that it cannot move, and the 2nd sounding mechanism 68 sounded by relative rotation of both the members 65 and 66. FIG.
[0032]
The first member 65 includes a ring-shaped flange portion 65a and a cylindrical portion 65b having a diameter smaller than that of the flange portion 65a, and is provided on the spool shaft 15 so as not to rotate but to move in the axial direction. A large number of hemispherical sound holes 65c are formed side by side in the circumferential direction on the front end surface of the flange portion 65a. An oblong locking hole 65d that locks the spool shaft 15 in a non-rotatable manner is formed in the inner peripheral portion of the cylindrical portion 65b. 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 surface of the cylindrical portion 65 b comes into contact with the drag disk 62 a of the friction portion 62.
[0033]
The second member 66 is opposed to the first member and is rotatably provided relative to the first member 65. The second member 66 is screwed into the spool shaft 15 and has a cylindrical shape facing the first member 65 so as to cover the flange portion 65a. It is a member which protrudes. The second member 66 is attached to the knob body 70, the nut body 72 that is non-rotatable and axially movable to the knob body 70, and is screwed into the spool shaft 15, and between the nut portion 72 and the first member 65. And a spring member 73 arranged.
[0034]
The knob body 70 is a cylindrical member with a flange made of synthetic resin, for example, injection molded. The knob body 70 includes an operation portion 70a formed on the front surface, a cover portion 70b formed with a circular recess opening on the rear end surface side, and a rear end surface from the operation portion 70a side through the inner peripheral surface of the cover portion 70b. For example, four locking grooves 70c formed at intervals in the circumferential direction and along the spool shaft 15 direction.
[0035]
The operation unit 70a is a protrusion formed in a substantially trapezoidal shape along the diameter. The cover part 70b protrudes in a cylindrical shape toward the first member 65 so as to cover the flange part 65a, and the rear end surface 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 portion 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. A round hole for forming the locking groove 70 c is hidden by a seal 70 d attached to the front surface of the knob body 70. Thus, by sticking the seal 70d and closing the round hole, even if the locking groove 70c is formed by the round hole for molding, foreign matters such as water are difficult to enter the knob body 70.
[0036]
At the center of the knob main body 70, a nut mounting portion 70e is formed on which a square nut portion 72 is mounted so that it cannot rotate but can move in the axial direction. A mounting hole 70g for accommodating the second sounding mechanism 68 is formed on the rear surface of the knob body 70. The nut portion 72 is screwed into a male screw portion 15 a formed at the tip of the spool shaft 15. The spring member 73 is mounted in a compressed state between the nut portion 72 and the first member 65.
[0037]
The connecting member 67 is a member formed by bending an elastic metal wire. The connecting member 67 is formed so as to be compressed into a quadrangle when attached, and to be slightly expanded when not attached. The square corner portion 67a protrudes radially outward from the flange portion 65a and is locked to the formation end 70f of the locking groove 70c, and the contact portion 67b connecting the corner portion 67a is formed on the flange portion 65a of the first member 65. Touch the rear side. As a result, the first member 65 is stored in a state in which the first member 65 is prevented from being detached from the cover portion 70b.
[0038]
As shown in FIG. 7, the second sound generation mechanism 68 includes a sound output hole 65c formed in the flange 65a of the first member 65, a sound output pin 77 mounted in the mounting hole 70g, and a sound output pin 77. And a coil spring 78 that urges toward the sound output hole 65c. A large number of sound output holes 65c are formed at intervals in the circumferential direction at positions that can face the mounting holes 70g. The sound output pin 77 is a pin having a central portion with a large diameter, a tip and a rear end with a small diameter, and a tip that is rounded into a hemisphere. When the knob body 70 and the first member 65 are relatively rotated during drag operation, The collision with the outlet hole 65c is repeatedly pronounced.
[0039]
As shown in FIG. 4, the drag disk 62 a of the friction portion 62 is a metal disk member that contacts the first member 65 and cannot rotate with respect to the spool shaft 15. The drag disk 62 b is a disc member made of, for example, felt that is rotatable with respect to the spool 4 and the spool shaft 15. The drag disk 62 c 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 that is 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 that engages a chamfered portion 15b formed parallel to each other at the tip of the spool shaft 15. A pair of ears 62f projecting radially outward is formed on the outer peripheral surface of the drag disk 62c. The ears 62f are along the inner peripheral surface of the cylindrical portion 4d of the bobbin trunk 4a along the axial direction. The locking groove 4f formed in this way is locked. As a result, the drag disk 62 c is not rotatable with respect to the spool 4.
[0040]
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 that of the connecting member 67, and each corner 75a protrudes radially outward from the drag disk 62a and is formed on the inner peripheral surface of the tubular portion 4d of the bobbin trunk 4a. The contact portion 75b is brought into contact with the drag disk 62a and the drag disks 62a to 62d are prevented from coming off. Thereby, even if the knob part 61 is removed from the spool shaft 15, the drag disks 62a to 62d do not fall off.
[0041]
The seal member 63 includes an attachment portion 63a attached to the first member 65 in the annular groove 65e, a first seal portion 63b extending from the attachment portion 63a toward the inner peripheral surface of the spool ring collar 55, and a first portion from the attachment portion 63a. A second seal portion 63c extending toward the 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 to the annular groove 65e having a rectangular cross section. The first seal portion 63b seals the gap between the spool 4 and the first member 65, and has a tapered cross-sectional lip portion that contacts the inner peripheral surface of the inner cylindrical portion 55b of the spool ring collar 55 of the spool 4 at the tip. 63d. Thus, since the lip portion 63d having a 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 provided. An increase in rotational resistance when the spool 4 rotating relative to the spool shaft 15 rotates relative to the spool shaft 15 can be suppressed. The second seal portion 63c seals the gap between the first member 65 and the second member of the knob portion 61, and has a rectangular cross section that contacts the rear end surface of the cover portion 70b.
[0042]
Here, since the second member 66 of the knob portion 61 protrudes toward the first member 65 so as to cover the flange portion 65 a of the first member 65, it is disposed between the spool 4 and the first member 65. By bringing the seal member 63 into contact with the protruding portion, 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 sealed simultaneously. Therefore, it is possible to prevent the liquid from entering the friction portion 62 with a simple seal structure.
[0043]
The first sound generation mechanism 64 is a mechanism that generates a sound when the spool shaft 15 and the spool 4 rotate relative to each other by the operation of the drag. As shown in FIG. 3, the first sound generation mechanism 64 collides with the sound output member 81 that is non-rotatably mounted on the spool shaft 15 and swingably mounted on the back surface of the support portion 4 e of the spool 4. And a spring member (not shown) that urges the claw member 82 toward the sound output member 81.
[0044]
[Reel operation and operation]
Adjust the drag force according to the size and type of fish before fishing. To adjust the drag force, the knob body 70 is turned. When the knob body 70 is rotated, 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 into 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 sound output pin 77 repeats the collision with the sound output hole 65c at a predetermined interval and generates a light click sound with good crispness.
[0045]
At the time of casting, the bale arm 44 is reversed to the yarn releasing posture. As a result, the first bail support member 40 and the second bail support member 42 swing. In this state, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then released vigorously due to 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, and 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.
[0046]
When fishing, waves can get on the reel and the reel can get wet. 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 gap. For this reason, once the drag force is adjusted, the drag force is less likely to fluctuate due to water wetting.
[0047]
[Other Embodiments]
(A) In the above-described embodiment, the two gaps are sealed by the elastic sealing member, but a hard ring-like or cylindrical 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 required separately.
[0048]
(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 portion 61 is loosened and the drag mechanism 60 is deactivated, the knob portion 61 moves forward in the spool axial direction, and therefore the second seal portion 63c of the seal member 63 separates from the rear end surface of the second member 66. To do. However, in a normal drag operation state, the second seal portion 63c can contact the rear end surface of the second member 66 and seal the gap between the members 65 and 66.

【The invention's effect】
According to the present invention, since the second member of the knob portion protrudes toward the first member so as to cover the flange portion of the first member, for example, a seal member disposed between the spool and the first member Is also brought into contact with the protruding portion, so that the gap between the spool and the first member and the gap between the first member and the second member can be sealed simultaneously. Therefore, it is possible to prevent the liquid from entering the friction portion with a simple seal structure.
