Description

  The present invention relates to a drag knob assembly, and more particularly to a spinning reel that can be attached to a spool shaft of a spool of a spinning reel that feeds a fishing line forward and adjusts the drag force of a drag friction portion for applying a drag force to the spool. The present invention relates to a reel drag knob assembly.

  In general, a front drag type spool of a spinning reel that feeds a fishing line forward 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 a spool shaft and a spool rotatably supported by the spool shaft, and is a drag knob assembly for adjusting a drag force by being screwed to the spool shaft, a drag knob assembly, and a spool. And a drag friction part having one or a plurality of drag washers provided therebetween. The drag knob assembly is disposed so as to come into contact with the drag friction portion, and the drag friction portion is usually mounted in a circular recess formed in the front portion of the spool.

In this type of drag mechanism, a mechanism that allows a liquid to enter the drag friction portion with a simple seal structure is known (for example, see Patent Document 1). In the conventional drag mechanism, the drag knob assembly includes a first member having a flange portion and a second member that is screwed onto the spool shaft. The second member is formed to project in a cylindrical shape toward the first member so as to cover the collar portion. In addition, a seal member is provided for simultaneously sealing the gap between the spool and the drag knob assembly and the gap between the first member and the second member. The seal member is mounted on the outer peripheral surface of the first member, the front surface is in contact with the rear end surface of the cylindrical portion of the second member, and the outer peripheral portion is in contact with the inner peripheral surface of the spool.

  In the conventional configuration, since two gaps are sealed by one seal member, liquid enters the inside of the drag friction portion through the outer periphery of the spool shaft from the gap between the first member and the second member. Can be prevented.

  However, in the conventional configuration, for example, when water is poured into a bucket or the like for cleaning, the seal member may be pushed down and deformed by water pressure. When the seal member is deformed, a gap is generated between the seal member and the rear end surface of the cylindrical portion of the second member, and there is a possibility that the liquid flows into the drag knob assembly.

  An object of the present invention is to prevent the inflow of liquid into the drag knob assembly even when water pressure acts on the seal member.

  The spinning reel drag knob assembly according to the first aspect of the present invention can be attached to the spool shaft of the spinning reel spool that feeds the fishing line forward, and adjusts the drag force of the drag friction portion for applying the drag force to the spool. The spinning reel drag knob assembly includes a knob portion, a first seal member, and a second seal member. The knob portion has a collar portion, and is provided with a first member that is not rotatable on the spool shaft and is movable in the axial direction. The knob portion is provided to be rotatable relative to the first member, and is screwed onto the spool shaft and covers the collar portion. A second member having a protruding portion that protrudes in a cylindrical shape toward the first member, and a connecting member that connects the first member and the second member so as not to move in the axial direction and to be rotatable. It is for adjustment. The first seal member is a member that is disposed between the spool and the first member and seals a gap between the spool and the first member. The second seal member is disposed between the first seal member and the second member, has a cylindrical contact portion that can contact the outer peripheral surface of the protruding portion of the second member, and the first member and the second member It is a member which seals the clearance gap between.

  In this drag knob assembly, the second seal member disposed between the first member and the second member has a cylindrical contact portion that contacts the outer peripheral surface of the cylindrical protrusion of the second member. The gap between the first member and the second member is sealed by the second seal member. In addition, the first seal member disposed between the spool and the first member seals between the spool and the first member. Here, the 2nd seal member is contacting the outer peripheral surface of the protrusion part of the 2nd member by the cylindrical contact part. For this reason, when the 1st seal member and the 2nd seal member are formed in one, even if water pressure acts on the 1st seal member and it is pushed down, it becomes difficult to change the 2nd seal member. For this reason, even if water pressure acts on the two seal members, it becomes difficult for the liquid to flow into the drag knob assembly from between the first member and the second member. In addition, when the first seal member and the second seal member are separated, the second seal member is less likely to be deformed even if the first seal member is deformed, and liquid is further added to the inside of the drag knob assembly. It becomes difficult to flow in.

  The spinning reel drag knob assembly according to a second aspect of the present invention is the knob according to the first aspect, wherein the second seal member further has an annular recess formed on the inner peripheral side of the contact portion and engaged with the end surface of the protruding portion. In this case, the inner peripheral surface can be sealed in addition to the outer peripheral surface of the rear end portion of the protruding portion, so that the liquid is less likely to flow into the drag knob assembly.

  A spinning reel drag knob assembly according to a third aspect of the present invention is the knob according to the first or second aspect, wherein the first member has an annular groove on the outer peripheral surface, and the first seal member is a retaining ring attached to the annular groove. Therefore, the movement in the direction away from the second seal member is restricted. In this case, since the backward movement of the first seal member can be restricted by the retaining ring, it is not necessary to directly attach the first seal member to the annular groove or the like. For this reason, a 1st seal member can be reinforced by putting a backup ring etc., and even if a hydraulic pressure acts on a 1st seal member, it can make it difficult to deform | transform a 1st seal member.

  A spinning reel drag knob assembly according to a fourth aspect of the present invention is the knob according to any one of the first to third aspects, wherein the first seal member has a lip portion having a tapered cross section that contacts the inner peripheral surface of the spool. In this case, since the contact area between the spool and the first seal member is reduced, even if the spool and the first seal member rotate relative to each other, it is difficult to affect the rotation of the spool.

  A spinning reel drag knob assembly according to a fifth aspect of the present invention is the knob according to any one of the first to fourth aspects, wherein the knob portion is disposed between the first member and the second member. And a sound generation mechanism that generates sound by relative rotation. In this case, even if a sound generation mechanism is provided between the first member and the second member, the inflow of liquid into the drag knob assembly can be prevented.

  A spinning reel drag knob assembly according to a sixth aspect of the present invention is the knob according to the fifth aspect, wherein the first member is made of metal, and the sound generation mechanism is non-rotatably mounted on the front surface of the collar portion of the first member. A synthetic resin sounding plate having a plurality of sounding recesses formed at intervals in the circumferential direction, and a striking member movably mounted on the second member while being biased toward the sounding recesses; ,have. In this case, since the first member is made of a metal having high heat resistance, even if heat from the friction portion is transmitted, problems due to heat hardly occur. Further, by making the portion where the sound output recess is formed from a synthetic resin, the sound output recess can be easily manufactured, and, for example, by using a synthetic resin having high slidability such as polyacetal, it is strong. Even if a striking force is applied, it can be operated with a light force, and the durability of the sound output recess is improved.

  The spinning reel drag knob assembly according to a seventh aspect of the present invention is the knob according to any one of the first to sixth aspects, wherein the second member includes a knob body, a nut portion, and a spring member. The knob body is made of a synthetic resin knob body having a disk portion and a projecting portion having a smaller diameter than the disk portion, and a metal disk-shaped cover portion fixed to the front surface of the knob body so as to cover the disk portion. And a metal operation knob fixed to the front surface of the cover portion along the radial direction. The nut portion is attached to the knob body so as not to rotate and to move in the axial direction, and is screwed onto the spool shaft. The spring member is a member disposed between the nut portion and the first member.

  In this case, since the front surface of the collar portion of the knob body made of synthetic resin is covered with the metal cover portion, the design of the front surface of the drag knob assembly is improved and the front surface is hardly damaged. In addition, it is possible to easily form the structure for housing the sound generation mechanism and the collar portion of the first member by molding a synthetic resin.

  According to this invention, the 2nd seal member is contacting the outer peripheral surface of the protrusion part of the 2nd member by the cylindrical contact part. For this reason, when the 1st seal member and the 2nd seal member are formed in one, even if water pressure acts on the 1st seal member and it is pushed down, it becomes difficult to change the 2nd seal member. For this reason, even if water pressure acts on the two seal members, it becomes difficult for the liquid to flow into the drag knob assembly from between the first member and the second member. In addition, when the first seal member and the second seal member are separated, the second seal member is less likely to be deformed even if the first seal member is deformed, and liquid is further added to the inside of the drag knob assembly. It becomes difficult to flow in.

The bail arm 34 includes a fixed shaft 43 fixed to the front end of the first bail support member 40 and cantilevered by the first bail support member 40, and a fixed shaft cover 44 disposed on the front end side of the fixed shaft 43. And a bail 45 for connecting the fixed shaft cover 44 and the second bail support member. Further, the bail arm 34 includes a fixing bolt 46 that fixes the fixed shaft 43 to the first bail support member 40, and a detent member 47 that prevents the fixing bolt 46 from rotating.

  As shown in FIGS. 4 to 6, the first bail support member 40 is a member made of an aluminum alloy whose outer surface is covered with a metal film formed by, for example, chromium plating. This chrome plating makes the surface hard and prevents damage to the outer surface due to contact with the fishing line. A first storage recess 40 a in which the head 46 a of the fixing bolt 46 is stored is formed on the distal end side of the outer surface of the first bail support member 40. Further, on the base end side, a circular second storage recess 40b in which a head 49a of a mounting bolt 49 for mounting the first bail support member 40 to the first rotor arm 31 is stored is formed.

The line roller 41 is formed with a first tube portion 41b and a second tube portion 41c with a small-diameter guide groove 41a formed at the center in the axial direction. The first cylinder portion 41b enters the fixed shaft cover 44 and has a smaller diameter than the second cylinder portion 41c. The second cylinder portion 41 c enters a circular third storage recess 40 e formed at the tip of the first bail support member 40. Inside the line roller 41, collars, spacers and washers for mounting the bearings 48a and 48b are mounted.

  As shown in FIG. 2, a reverse rotation prevention mechanism 50 for prohibiting the reverse rotation of the rotor 3 is disposed inside the connecting portion 30 of the rotor 3. The reverse rotation prevention mechanism 50 includes a roller type one-way clutch 51 on which an inner ring rotates freely. This reverse rotation prevention mechanism 50 always prohibits the reverse rotation of the rotor 3 in the yarn feeding direction, and does not take a state of permitting the reverse rotation.

  In addition to the first and second members 66 and 67, the knob portion 63 further includes a connecting member 74 that connects the first and second members 66 and 67 so as not to be axially movable and rotatable.

  The first member 66 is a metal member such as an aluminum alloy having a collar shape having a ring-shaped collar part 66a and a cylindrical part 66b having a smaller diameter than the collar part 66a. The first member 66 is provided on the spool shaft 15 so as not to rotate but to move in the axial direction. A sounding disc (an example of a sounding plate) 69 constituting the knob sound generating mechanism 68 is provided on the front end surface of the collar portion 66a so as to be integrally rotatable.

  The sound output disc 69 is a member made of synthetic resin, and a large number of sound output recesses 69a are formed on the front surface thereof at intervals in the circumferential direction. On the rear surface of the sound emitting disk 69, a plurality of connection protrusions 69b that fit into a plurality of connection holes 66e formed in the flange 66a are formed. As a result, the sound disk 69 is prevented from rotating with respect to the first member 66.

The connecting member 74 is a C-shaped spring member having four corner portions 74a corresponding to substantially square corners. The connecting member 74 is mounted on the inner peripheral surface of the projecting portion 75b by engaging the corner portion 74a with an annular groove formed on the inner peripheral surface of the projecting portion 75b. The connecting member 74 prevents the collar portion 66a from coming off when the three arc portions 74b between the corner portions 74a contact the rear surface of the collar portion 66a.

  The nut portion 72 is a hexagonal nut, for example, and is screwed into a male screw portion 25 b formed on the outer peripheral surface of the spool shaft 15 and compresses the spring member 73 in accordance with the rotation of the knob body 75.

  The first seal member 64 is a disk-shaped member made of, for example, synthetic rubber. The first seal member 64 is disposed between the inner peripheral surface of the mounting cylinder portion 53 a of the support cylinder portion 53 of the spool 4 and the outer peripheral surface of the cylindrical portion 66 b of the first member 66. The first seal member 64 is restricted from moving backward by a retaining ring 70 attached to the annular groove 66d. The first seal member 64 has an inner peripheral surface attached to the cylindrical portion 66 b of the first member 66, and an outer peripheral portion in contact with the inner peripheral surface of the mounting cylindrical portion 53 a of the support cylindrical portion 53. A disc-shaped reinforcing plate 81 made of, for example, a stainless alloy is embedded in the first seal member 64. The reinforcing plate 81 is inserted into the mold when the first seal member 64 is molded, and is insert-molded. A lip portion 64 a having a tapered cross section that contacts the inner peripheral surface of the mounting cylinder portion 53 a is formed on the outer peripheral portion of the first seal member 64. The lip portion 64a is inclined forward. Further, an annular protrusion 64b having a triangular cross section protruding forward is formed in the middle of the radial direction. The annular protrusion 64b contacts the back surface of the second seal member 65. Further, the front surface of the lip portion 64 a of the first seal member 64 is also in contact with the rear end portion of the outer peripheral surface of the second seal member 65.

The second seal member 65 includes a cylindrical contact portion 65a that can contact the outer peripheral surface of the protrusion 75b of the knob body 75 of the second member 67, and a rear end surface of the protrusion 75b that is formed on the inner peripheral side of the contact portion 65a. And an annular recess 65b that engages with the outer peripheral surface of the cylindrical member 66b of the first member 66.

  In the drag knob assembly 61 having such a configuration, the second seal member 65 disposed between the first member 66 and the second member 67 is in contact with the outer peripheral surface of the protruding portion 75 b of the second member 67. The second seal member 65 seals the gap between the first member 66 and the second member 67. Further, the space between the spool 4 and the first member 66 is sealed by the first seal member 64 disposed between the spool 4 and the first member 66. Here, the 2nd seal member 65 is contacting the outer peripheral surface of the protrusion part 75b of the knob main body 75 of the 2nd member 67 with the cylindrical contact part 64a. For this reason, when the first seal member 64 and the second seal member 65 are integrally formed, the second seal member 65 is not easily deformed even if water pressure acts on the first seal member 64 and is pushed down. For this reason, even if water pressure acts on the two seal members 64 and 65, it is difficult for the liquid to flow into the drag knob assembly from between the first member 66 and the second member 67. In addition, since the first seal member and the second seal member are separate, even if the first seal member 64 is deformed, the second seal member 65 is less likely to be deformed, and the liquid is contained inside the drag knob assembly 61. Furthermore, it becomes difficult to flow in.

  As shown in FIG. 10, the knob sound generating mechanism 68 includes a sounding disc 69 having a sounding recess 69a, a striking pin (an example of a striking member) 82 movably attached to the knob main body 75, and a striking pin.

The drag washer 62 b is a metal disk member that can rotate integrally with the spool 4. The drag washer 62c is a metal disk member that cannot rotate with respect to the spool shaft 15 similarly to the drag washer 62a. The drag washer 62d is a disc member made of, for example, felt or graphite that is rotatable with respect to the spool 4 and the spool shaft 15. An oblong locking slot 62e that engages with a locking surface 15a formed on the front end side of the spool shaft 15 is formed at the center of the drag washers 62a and 62c. On the outer peripheral surface of the drag washer 62b, a plurality of (for example, eight) ears 62f projecting radially outward are formed. The ear portions 62f are arranged on the inner peripheral surface of the drag storage cylinder portion 52 at intervals in the circumferential direction, and are locked to a plurality of locking recesses 52a formed along the axial direction. As a result, the drag washer 62 b can rotate integrally with the spool 4.

  The drag washers 62 a to 62 d are prevented from being detached by a first support part 56 that supports the support cylinder part 53. Accordingly, the drag washers 62a to 62d cannot be attached or detached unless the retaining spring 55 disposed in front of the support cylinder portion 53 is removed.

  The drag sound generation mechanism 85 is a mechanism that generates a sound when the spool shaft 15 and the spool 4 are relatively rotated by the operation of the drag. As shown in FIG. 8, the drag sound generation mechanism 85 repeatedly hits the first sound generation member 86 with a first sound generation member 86 that is mounted on the back surface of the rear flange portion 4 h of the spool 4 and rotates together with the spool 4. 2 sound generating members 87.

  The first sounding member 86 has a cylindrical shape with a hook, and is a metal member in which a large number of arcuate sound emitting recesses 86a are formed on the inner peripheral surface. A name plate 88 is disposed on the rear surface of the first sounding member 86, and the first sounding member 86 together with the name plate 88 is screwed to the back surface of the rear flange portion 4h.

  The second sound generation member 87 includes two striking pins 87a that advance and retreat toward the sound output recess 86a, and two spring members 87b that bias the two striking pins 87a toward the sound output recess 86a. Yes. The striking pin 87a is housed in a tubular housing member 89 that is non-rotatably engaged with the second locking surface 57d of the second support portion 57. The storage member 89 has a thick cylindrical storage body 89a having two storage grooves 89c for storing the striking pin 87a so as to be able to advance and retract, and is screwed to the storage body 89a to close the storage groove 89c. And a disc-shaped cover 89b that engages with the locking surface 57d. The two storage grooves 89c of the storage main body 89a open to the outer peripheral surface of the storage main body 89a, and are formed so that the interval between the two storage grooves 89c on the opening side is narrow. A locking slot 89d that engages with the second locking surface 57d is formed on the inner peripheral surface of the cover 89b. A washer 101 is disposed between the storage member 89 and the support wall portion 4 e of the spool 4.

  On the rear surface of the cover 89b, for example, three spool position adjusting washers 102 made of, for example, synthetic resin, which are engaged with the first locking surface 57c of the second support portion 57, and 2 for restricting the movement of the spool 4 to the rear. A sheet of restricting washers 103 and 104 is attached. The restricting washers 103 and 104 are formed with locking slots 103 a and 104 a that engage with the locking surface 15 a of the spool shaft 15 in the inner peripheral portion, and are not rotatable with respect to the spool shaft 15. The restriction washer 104 is a stepped washer, and holds the third seal member 105 together with the restriction washer 103. The outer peripheral portion of the third seal member 105 is in contact with the inner peripheral surface of the first sounding member 86. The third seal member 105 is provided in order to prevent liquid from flowing into the spool 4 including the friction portion 62 from the rear surface of the spool 4.

[Reel operation and operation]
Adjust the drag force according to the size and type of fish before fishing. To adjust the drag force, the drag knob assembly 61 is rotated. When the drag knob assembly 61 is rotated, for example, clockwise, the first member 66 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 66 and the second member 67, the striking pin 82 repeats the sound and collides with the recess 69a at a predetermined interval, and a crisp light click sound is generated.

  At the time of casting, the bale arm 34 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 assembly 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 34 is returned to the yarn winding position by the bale reversing mechanism (not shown). The fishing line moves from the bail 45 to the line roller 41 and is wound around the spool 4.

  When fishing, when a large fish is applied and the load on the line roller 41 increases, the fixed shaft 43 that is cantilevered by the first bail support member 40 vibrates with a slight inclination due to the fluctuation of the load. There is. In such a case, in the present embodiment, since the fixing bolt 46 for fixing the fixing shaft 43 to the first bail support member 40 is prevented from rotating by the rotation preventing member 47, the fixing bolt 46 is difficult to loosen.

  When the spinning reel is washed by immersing it in a bucket containing fresh water after fishing, the first seal member 64 may be pushed backward by water pressure and deformed. If the first seal member 64 is used to seal the gap between the first member 66 and the second member 67, the deformation of the first seal member 64 may cause liquid to flow into the drag knob assembly 61 from the gap. . However, in this embodiment, the cylindrical contact portion 65a that contacts the outer peripheral surface of the protruding portion 75b of the second member is provided in the second seal member 65, so even if the first seal member 64 is deformed by water pressure, It is difficult for liquid to enter the inside of the drag knob assembly 61. For this reason, it is difficult for the liquid to flow into the friction portion 62 from the inside of the drag knob assembly 61 through the outer peripheral portion of the spool shaft 15, and the fluctuation of the drag force due to the wetness of the friction portion 62 is less likely to occur.

[Other Embodiments]
(A) In the above-described embodiment, the first seal member 64 and the second seal member 65 are separated from each other, but may be integrally formed. Also in this case, the gap between the first member 66 and the second member 67 can be reliably sealed by the contact portion of the second seal member.

  (B) In the embodiment, the reinforcing plate 81 is embedded in the first seal member 64, but the reinforcing plate may not be embedded. In this case, since the entire first seal member has elasticity, it may be attached to an annular groove formed on the outer peripheral surface of the first member to prevent it from coming off.
