Description

  The present invention relates to a fishing spinning reel provided with a drag device that provides resistance to rotation of a spool around which a fishing line is wound.

  2. Description of the Related Art Conventionally, a drag device incorporated in a fishing spinning reel is, for example, as disclosed in Patent Document 1, in front of a spool that is rotatably supported at the tip of a spool shaft that moves back and forth by the rotation of a handle. The brake member is housed in the portion, and the adjustment knob that is screwed to the tip of the spool shaft is rotated to apply a pressing force to the brake member, thereby adjusting the frictional engagement force of the spool with respect to the spool shaft. ing.

  Further, in the drag device having the above-described structure, the spool is rotatably supported via a ball bearing (radial bearing) with respect to the spool shaft so that the fishing line can be drawn smoothly when the drag is operated. The rear end of the spool is fixed to the spool shaft so that the ball bearing is not damaged when the drag is tightened (the outer ring supported by the spool is damaged or deformed due to excessive thrust load applied by drag tightening). It is restricted in the axial direction in a state where it is in contact with a friction plate (a facing portion where the rear end portion of the spool faces).

JP 2007-202416 A

  In the drag device having the above-described structure, when the adjusting knob is rotated to press the braking member, the spool rear end is also in pressure contact with the friction plate that regulates the spool in the axial direction. And the friction force (pressure contact force) of the rear end portion of the spool against the friction plate act (a plurality of friction forces having different friction characteristics act). For this reason, the drag slipout becomes unstable and worse, and particularly in a region where the drag braking force is small where a smooth slipout is required, this effect is likely to occur and a stable drag performance cannot be obtained. Arise. In particular, the frictional force at the rear end of the spool with respect to the friction plate is easily affected by the material and surface treatment of the spool and the friction plate, and adhesion of oil, grease, etc., so that the drag characteristics become more unstable.

  Further, in a situation where a drag force is applied, a braking force is applied to the fishing line drawn from the spool, so that forces in various directions (forces in the thrust direction, radial direction, etc.) act on the spool. It becomes like this. In particular, the spool of a fishing spinning reel is moved back and forth through the spool shaft by its unique oscillating mechanism, so that the fishing line is wound evenly in the axial direction. Depending on the spool diameter and position of the fishing line when the force is acting (position in the front-rear direction (axial direction) on the spool winding surface of the spool), the spool has various directions via the drawn fishing line. In the situation where the frictional force by the braking member and the characteristic of the frictional force at the rear end of the spool against the friction plate are different as described above, the braking force on the drawn fishing line is not stable.

  As a result, when the fishing line is pulled out, the initial stage of slipping is not stable as described above, and in the situation where the drag force is applied, an intermittent change in braking force (stick-slip phenomenon) occurs. Further, there is a problem that the possibility that the fishing line is cut or the mouth of the hung fish is raised is increased.

  The present invention has been made by paying attention to the problem inherent to spinning reels in that the braking force changes intermittently due to different forces acting in various directions on the spool when the drag force is applied as the spool moves back and forth. The purpose of the fishing spinning reel is provided with a drag device capable of obtaining a stable drag performance over the entire range of drag action, including a region where the drag braking force is small, which requires smooth sliding. Is to provide.

  In order to achieve the above object, a fishing spinning reel according to the present invention accommodates a braking member in a recess formed in a front portion of a spool rotatably supported by a spool shaft, and a tip portion of the spool shaft. In the configuration provided with a drag device that adjusts the frictional coupling force in the rotational direction of the spool with respect to the spool shaft by changing the pressure contact force of the braking member by rotating the adjusting body screwed to the spool shaft. And a pressure-contacting portion of the braking member acting on the spool, which is provided between the rear end portion of the spool and is disposed between the rear end portion and the facing portion. And a thrust bearing for supporting the force in the axial direction.

  According to the fishing spinning reel having the above-described structure, when the drag device adjusting body mounted on the front portion of the spool is rotated to tighten the drag, the spool has a tightening amount of the drag device adjusting body. As the pressure contact force of the braking member that changes with the load, a load along the spool axial direction (a load toward the spool rear end side) is applied. Since this load is supported by a thrust bearing inserted between the rear end portion of the spool and the opposed portion, not only the initial stage of braking when the braking force starts to act, but also the drag force is set to a large value in the spool. Even when a large thrust load is applied, friction resistance is not applied to the spool (in addition to the frictional force of the braking member, for example, friction characteristics such as the frictional force of the rear end of the spool against the friction plate as in Patent Document 1). Without any additional frictional force), smooth drag out performance is obtained. That is, it is possible to obtain a stable drag performance over the entire region of the drag action including the region where the drag braking force is required to be smoothly started.

  In the above configuration, the spool is preferably supported so as to be rotatable with respect to the spool shaft via a radial bearing which is a ball bearing, for example. In that case, since the rotation of the spool becomes smoother, it becomes possible to further smoothly draw out the fishing line when the drag force is operated, and it acts on the spool when the drag force is applied as the spool moves back and forth. Thrust bearings and radial bearings can support different forces in various directions in cooperation. In other words, a problem inherent to spinning reels is that the braking force changes intermittently (stick-slip phenomenon) due to different forces in various directions acting on the spool when the drag force acts as the spool moves back and forth. The bearing can solve the problem efficiently and effectively, and the stabilization of such a braking force can reduce the possibility that the fishing line breaks or the fish mouth breaks. In this case, the thrust bearing can support the thrust load even if a large thrust load is applied to the radial bearing via the spool with a large drag force, thus preventing the radial bearing from being damaged or deformed. You can also.

  Hereinafter, embodiments of a spinning reel for fishing according to the present invention will be described in detail with reference to the drawings. In the spinning reel for fishing, the rotor is rotationally driven by winding a handle provided on the reel body, and the spool is reciprocated in the front-rear direction, whereby the rotor rotates with respect to the spool. The fishing line is wound evenly through the fishing line guide portion. In the drawing, the main body structure of the spinning reel is omitted because it is generally known, and a spool mounted on a spool shaft that is moved back and forth by a known oscillating mechanism mounted on the main body so as not to rotate, and the spool The drag device portion will be described in detail.

  FIG. 1 is a cross-sectional view of a spool portion of a fishing spinning reel according to a first embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of a portion A (a portion indicated by a circular two-dot chain line) in FIG. It is.

  A spool 1 around which a fishing line is wound has a cylindrical shape including a winding body 1a around which a fishing line is wound, a front collar 1b, and a rear cylindrical part (also referred to as a skirt) 1c. A substantially disc-shaped support wall (spool rear end) 1d is integrally formed on the inner side in the radial direction behind the rotating drum portion 1a. An opening 1e is formed at the center of the spool rear end 1d, and the spool shaft is reciprocated along the front-rear direction (axial direction) via an oscillating mechanism (not shown) in the opening 1e. 2 is inserted.

  In this embodiment, a cylindrical support member (also referred to as a spool metal) 3 is fitted on the spool shaft 2, and the support member 3 is fixed to the spool shaft 2 by a support pin 4. So that it cannot move in the axial direction. A radial bearing 5 serving as a ball bearing is provided between the rear end 1d of the spool and a substantially central portion of the support member 3, and the spool 1 is rotatably supported with respect to the spool shaft 2. . Here, the radial bearing 5 has its inner ring 5b supported and fixed to the support member 3, and its outer ring 5a supported and fixed to the spool 1 (spool rear end 1d).

  In the present embodiment, a projection 1f protruding toward the opening 1e is formed on the spool rear end 1d, and the reel body side of the outer ring 5a of the radial bearing 5 is positioned. Further, the support member 3 of the present embodiment is integrally formed with a flange 3 a that protrudes radially outward on the reel body side with respect to the radial bearing 5. In the present embodiment, the flange 3a constitutes a facing portion 10 that faces the spool rear end 1d.

  A spool click mechanism 7 is installed on the flange 3 a of the support member 3. The spool click mechanism 7 includes an annular spring 7d held by a cap-like spring holding member 7a fixed radially outward of the flange 3a and a pair of openings 7c formed in the annular wall 7b of the spring holding member 7a. The ring spring 7d is engaged with the inner surface unevenness 1h of the annular wall 1g formed radially outward of the spool rear end 1d, so that a click sound is generated when the spool 1 rotates. I am doing so.

  By the way, in a situation where a drag force is applied by a drag device, which will be described later, since a braking force is applied to the fishing line L drawn from the spool 1, forces in various directions (thrust direction, radial direction, etc.) are applied to the spool 1. ) Will work together. In particular, the spool 1 of the spinning reel for fishing as in the present embodiment is moved back and forth via the spool shaft 2 by a unique oscillating mechanism, whereby the fishing line L is wound evenly in the axial direction. Therefore, the winding diameter and position of the fishing line L when the drag force is acting (position in the front-rear direction (axial direction) on the winding body 1a of the spool 1; for example, the reel of FIG. Depending on the rear position P1 on the main body side and the front position P2 on the tip side, different forces act on the spool 1 in various directions via the drawn fishing line L.

  Therefore, in this embodiment, in order to support such different forces in various directions, a thrust bearing 50 as a ball bearing is further provided in addition to the radial bearing 5. In particular, in the present embodiment, the thrust bearing 50 has a spool rear end 1d and a support member 3 (opposing portion) to support a thrust force acting on the spool 1 (a pressure contact force of a braking member of a drag device described later). As a flange 3a). Here, the axial bearings 50a and 50b on both the left and right sides in the axial direction of the thrust bearing 50 are supported and fixed to the support member 3 (flange 3a) and the spool 1 (spool rear end 1d), respectively.

  A bent wall 7e that bends substantially perpendicularly to the annular wall 7b of the spring holding member 7a of the spool click mechanism 7 is sandwiched between the support member 3 and radially outward of the flange 3a of the support member 3. A ring-shaped spacer 8 is attached as described above, and this spacer 8 is interposed between the thrust bearing 50 and the bent wall 7e.

  A recess 1A is formed on the front side (spool front) of the spool rear end 1d. When the spool 1 rotates in the fishing line feeding direction, a drag device that applies a braking force to the rotation is provided. 20 is installed.

  The drag device 20 includes a drag force adjusting body (hereinafter referred to as an adjusting knob) 22 exposed forward from the recess 1A, and a friction braking unit (braking) disposed in the recess 1A and applying a braking force to the spool. Member) 30, and a pressing member 40 that is installed between the adjustment knob 22 and the friction braking portion 30 and applies an axial pressing force to the friction braking portion 30 when the adjustment knob 22 is rotated. ing.

  The adjustment knob 22 is integrated with a nut member 23 that is screwed into the tip of the spool shaft 2. When the adjustment knob 22 is screwed in, the adjustment knob 22 is disposed between the nut member 23 and the pressing member 40. The pressing member 40 presses the friction braking unit 30 through the pressing force of the compression coil spring (elastic member) 41.

  The friction braking portion 30 preferably has a multi-plate structure and is disposed along the outer peripheral surface of the support member 3, and a desired friction force (braking force) with the front surface 1 d ″ of the spool rear end portion 1 d. Specifically, the friction braking portion (braking member) 30 is, for example, a metal washer (in this embodiment, the inner peripheral portion of which is fitted to the support member 3 to prevent rotation). (In the form, it constitutes a ratchet ring) 31, a metal washer 32 that is rotatably arranged with respect to the support member 3, and a metal washer in which the inner peripheral portion is fitted to the support member 3 in a detent state 33, and a lining material 35 interposed therebetween, and the pressing member 40 rotates the adjusting knob 22 to press the compression coil spring 41 according to the screwing amount of the nut member 23. After being spooled by being pressed with Part 1d desired contact pressure between the front 1d "occurs, the frictional coupling force in the rotational direction of the spool 1 (braking force) is regulated.

  The pressing member 40 holds a click plate 42 that engages with the irregularities 31a formed on the inner surface of the ratchet ring 31, and when the adjustment knob 22 is rotated, the click plate 42 engages with the irregularities 31a. It is configured to generate a click sound.

Next, the effect of the drag operation in the fishing spinning reel configured as described above will be described.
Since the spool 1 is rotatably supported with respect to the spool shaft 2 (supporting member 3 fixed to the spool shaft 2) via the radial bearing 5, the fishing line L can be smoothly pulled out when the drag force is operated. It becomes possible to. In addition, when the adjustment knob 22 of the drag device 20 attached to the front portion of the spool 1 is rotated to tighten the drag, a braking force acts on the spool 1 via the friction braking portion 30, and the spool 1 A braking force (drag force) can be applied to the rotation. In this case, the spool 1 has a load along the direction of the spool shaft 2 (a load toward the spool rear end 1d side) as a pressure contact force of the friction braking portion 30 that varies with the tightening amount of the adjustment knob 22 of the drag device 20. However, since this load is supported by the thrust bearing 50 inserted between the spool rear end 1d and the facing portion 10 (support member 3), the braking force starts to act. Of course, even if the drag force is set to a large value and a large thrust load is applied to the spool 1, no frictional resistance is given to the spool 1 (in addition to the friction force by the friction braking unit 30). (For example, without applying a further frictional force having a different frictional characteristic such as the frictional force of the rear end of the spool against the friction plate as in Patent Document 1) Performance is obtained. That is, it is possible to obtain a stable drag performance over the entire region of the drag action including the region where the drag braking force is required to be smoothly started.

  In the present embodiment, the thrust bearing 5 and the radial bearing 50 can support different forces in various directions acting on the spool 1 when the drag force is applied as the spool 1 moves back and forth. In other words, a problem inherent to spinning reels is that the braking force changes intermittently (stick-slip phenomenon) when different forces in various directions are applied to the spool 1 when a drag force is applied as the spool 1 moves back and forth. 5 and the radial bearing 50 can solve the problem efficiently and effectively, and the stabilization of such braking force can reduce the possibility that the fishing line breaks and the hooked fish breaks. In this case, the thrust bearing 50 can support the thrust load even if a large thrust load is applied to the radial bearing 5 through the spool 1 by setting the drag force large. Deformation can also be prevented.

  Further, in the present embodiment, the cylindrical support member 3 is fitted and fixed to the spool shaft 2, and the opposing portion 10 is formed integrally with the support member 3, so that the assembling accuracy can be improved and the bearing can be improved. It becomes possible to perform the positioning of 5, 50 with high accuracy.

Next, another embodiment of the present invention will be described.

  In this embodiment, the radial bearing 5 is excluded from the configuration of the first embodiment, and other configurations are the same as those of the first embodiment. Even in such a configuration, since the axial load acting on the spool 2 in accordance with the drag pressure contact force can be supported by the thrust bearing 50, the drag force is set to be large as well as the initial stage of braking where the braking force starts to act. Even if a large thrust load is applied to the spool 1, no frictional resistance is given to the spool 1 (in addition to the frictional force by the friction braking unit 30, for example, after the spool against the friction plate as in Patent Document 1). A smooth drag-out performance of the drag can be obtained without applying a further frictional force having a different frictional characteristic such as a frictional force at the end.

  In this embodiment, the support member 3 is excluded from the configuration of the first embodiment, and the inner ring of the radial bearing 5 is directly supported by the spool shaft 2. Further, the facing portion 10A facing the spool rear end portion 1d is configured by a stopper 60 (specifically, a spool-side surface 60a of the stopper 60) applied to the step portion 2A formed on the spool shaft 2. A thrust bearing 50 is inserted between the stopper 60 and the spool rear end 1d, and a protrusion 60b is formed on the stopper 60 to position the radial bearing 50 in the radial direction.

  As described above, the radial bearing 5 that rotatably supports the spool 1 may be disposed directly with respect to the spool shaft 2, and the opposing portion 10 is also axially disposed with respect to the spool shaft 2. You may comprise by the member (for example, stopper 60 as shown in figure) fixed so that it might not move.

There are other configurations that can be modified as appropriate.

  For example, the configuration of the drag device 20 is merely an example, and is not limited to the configuration shown in the figure. Further, the arrangement configuration example of the protrusions for positioning and holding various bearings can be appropriately modified. Further, the rear end surface 1d 'of the spool rear end 1d or the facing portion facing the thrust bearing 50 may be a member integrated with the spool shaft 2, and as described above, the integrated member itself may be used. The facing portion may be formed, or a different member such as a friction plate may be attached to the integrated member to constitute the facing portion. Although not shown, a configuration in which both the support member and the radial bearing are excluded from the above-described first embodiment also falls within the scope of the present invention.
