Spinning reel rotor braking device

  The present invention relates to a rotor braking device, and more particularly to a spinning reel rotor braking device that brakes a rotor rotatably mounted on a reel body in response to swinging of a bail arm that swings between a yarn winding posture and a yarn releasing posture. About.

  In general, a spinning reel rotor is provided with a bail arm for guiding fishing line to a spool. The bail arm can take a line-winding posture that guides the fishing line to the outer periphery of the spool when winding the fishing line, and a line-releasing posture that is tilted from the line-winding position so as not to get in the way when the fishing line is unwound from the spool. In order to maintain the bale arm in the yarn winding posture and the yarn releasing posture, and to return the yarn releasing posture to the yarn winding posture in conjunction with the rotation of the rotor in the yarn winding direction, a bale reversing device is provided in the rotor. (For example, refer to Patent Document 1).

Conventional bail tripping device, the tip in the vicinity of the pivot center of the bail arm is engaged, the toggle spring mounted on the rotor, the tip is locked in the vicinity of the pivot center of the bail arm, the proximal end reel A rod-shaped moving member that moves back and forth toward the main body and a switching protrusion provided on the reel main body so as to come into contact with the moving member. The toggle spring distributes and urges the bale arm in two postures, and holds the bail arm in two postures. When the bail arm swings in the yarn releasing posture, the moving member moves backward to a position where it contacts the switching protrusion. When the rotor rotates in the yarn winding direction, the rotor moves forward in contact with the switching projection. The forward movement causes the toggle spring to contract, and the toggle spring returns the bale arm to the yarn winding posture.

  Spinning reels with improved rotation transmission efficiency are easy to rotate in the yarn winding direction. When the rotor rotates, the rotational phase may easily shift even if the rotor is rotated to a rotational phase suitable for casting and summing.

In the conventional configuration, in order to prevent the rotation of the rotor in the yarn releasing posture, a braking member that contacts the reel body and brakes the rotor is mounted on the moving member. When the moving member moves to the contact position, the braking member contacts the front surface of the reel body and is compressed to brake the rotor. When the rotor is elastically braked at the time of the bale reversal in this way, the rotation of the rotor can be prevented and the rotor can be rotated in the yarn winding direction as necessary.

  In the conventional configuration, the braking member mounted on the moving member contacts the reel body and is compressed to brake the rotor. For this reason, if the contact position of the moving member fluctuates back and forth due to manufacturing errors, mounting errors, etc., the compression amount of the braking member fluctuates. When the amount of compression varies, the braking force of the rotor varies, and the rotor cannot be stably braked. Therefore, an annular braking member made of elastic resin is mounted on the reel body, and the moving member is moved from the end of the braking member toward the outer surface in a direction intersecting the pressing direction of the braking member to be brought into contact with the braking member. It is possible.

  However, with such a configuration, braking is performed only at a portion where the moving member contacts the braking member, so that the braking force varies and the braking force may become unstable. When the braking force becomes unstable in this way, the predetermined braking force is not always exhibited, and the operability may be deteriorated.

  Therefore, a braking member having an annular friction portion made of an elastic resin that frictionally engages with the reel body and a plurality of engaging portions with which the protruding portions of the moving member engage is provided. It is further conceivable to frictionally slide the friction portion relative to the reel body when the protruding portion engages with the engaging portion. With such a configuration, braking is performed uniformly by the entire portion of the friction portion, so that the braking force can be stabilized.

  Such a brake member is an annular member made of an elastic resin, and for example, the entire friction portion is inserted into a mounting groove formed on the outer periphery of the front end portion of the reel body so that the friction portion slides on the reel body. It is mounted so that the inner peripheral surface comes into contact. As described above, when the friction member is mounted so that the entire inner peripheral surface thereof is in contact with the mounting groove, for example, if the braking member is distorted due to an error in the manufacturing process, a part of the friction portion is in good contact with the mounting groove. There is a risk that it will not. If a part of the friction part does not come into good contact with the mounting groove, the braking force varies and the braking force may become unstable.

The line roller 41 is rotatably attached to the tip of the first bail support member 40. The fixed shaft cover 47 has a deformed conical shape with a sharp tip. A bail 43 having a shape obtained by curving a wire in a substantially U shape is fixed between the distal end portion of the fixed shaft cover 47 and the second bail support member 42. The first and second bail support members 40 and 42, the line roller 41, the bail 43, and the fixed shaft cover 47 constitute the bail arm 17 that guides the fishing line to the spool 4. The bail arm 17 is swingable between a yarn winding posture shown in FIG. 3A and a yarn releasing posture reversed from the yarn winding posture shown in FIG.

  The bale reversing mechanism 18 is disposed in the storage space 48 of the first rotor arm 31. The bale reversing mechanism 18 is provided to return the bail arm 17 from the yarn releasing posture to the yarn winding posture in conjunction with the rotation of the rotor 3 and to maintain the state in both postures.

  As shown in FIGS. 3 to 6, the bail reversing mechanism 18 includes a toggle spring mechanism 50 that is swingably mounted on the first arm portion 31 b in the storage space 48, and can move substantially back and forth in the storage space 48. The mounted moving member 51, the switching member 52 detachably mounted on the flange portion 2d so as to be able to contact the moving member 51, the rotor braking mechanism 54 having the braking member 65 for braking the rotor 3, and the yarn release It has a regulating mechanism 75 that regulates the return of the bail arm 17 in the posture to the yarn winding posture.

  As shown in FIG. 3, the toggle spring mechanism 50 is disposed in the first rotor arm 31 so that the bail arm 17 can take a first position where the yarn winding posture is in a yarn winding posture and a second position where the bale arm 17 is in a yarn releasing posture. This is a mechanism for holding the bail arm 17 in the yarn winding posture and the yarn releasing posture. The toggle spring mechanism 50 has a rod 55 having one end locked to the first bail support member 40 and the other end extending along the first arm portion 31b, and a coil spring 57 that urges the rod 55 toward the advance side. doing.

  As shown in FIG. 4, the rod 55 has a locking portion 55 a that is bent toward the first bail support member 40 so that the rod 55 is locked in the engagement hole 40 a of the first bail support member 40. Yes. Further, the rod 55 has a locking projection 55b for locking the front end portion of the coil spring 57 at the intermediate portion, and has a curved portion 55c slightly curved at the rear end portion. A washer 56 with which the tip of the coil spring 57 abuts is attached to the locking projection 55 b, whereby force is uniformly transmitted from the tip of the coil spring 57 to the rod 55.

  The coil spring 57 is guided in contact with a guide sheet 34 made of synthetic resin such as polyamide synthetic resin, which is mounted on the arm portion 31b. The guide sheet 34 has a wall surface portion 34a that is bent so as to guide one side surface of the coil spring 57 and to lock the base end portion. The wall surface portion 34 a has a height that can contact the side portion and the base end portion of the coil spring 57. As a result, the coil spring 57 is easily expanded and contracted, and the arm portion 31b is not damaged when the coil spring 57 is expanded and contracted.

  The distal end portion of the coil spring 57 that is locked by the washer 56 has a smaller winding diameter than the other portions. As a result, a large gap is generated between the coil spring 57 and the rod 55 except at the tip, and even if the rod 55 changes its position inside the coil spring 57, the coil spring 57 is hardly deformed. A boss portion that contacts the inner peripheral surface of the base end portion of the coil spring 57, a cover portion that covers the outer peripheral surface of the base end portion, and the like may be provided to lock the base end portion of the coil spring 57. Further, the boss portion and the cover portion may be attached to the arm portion 31b so as to swing around an axis parallel to the swing axis of the first bail support member 40. For example, it is conceivable that an arc convex portion is formed on the base end surface of the boss portion and an arc concave portion that engages with the arc convex portion is formed in the arm portion 31b so that the boss portion can swing freely.

  The toggle spring mechanism 50 having such a configuration includes the coil spring 57 that is the axis of the swing shaft, the center position of the base end, the swing axis O of the first bail support member 40 (the axis of the mounting pin 39), and the like. Are arranged so that the locking position of the rod 55 with respect to the first bail support member 40 is different in the yarn winding posture and the yarn releasing posture. The position overlapping this line segment is the dead point of the toggle spring mechanism 50 (the position where the coil spring 57 is most compressed). Thereby, the toggle spring mechanism 50 can distribute and urge the bail arm 17 in both postures with the dead center in between, and can hold the posture in both postures. The dead point of the toggle spring mechanism 50 is biased toward the yarn releasing posture.

  The moving member 51 is, for example, a member formed by bending both ends of a metal wire such as a stainless alloy in directions different by 90 degrees. The moving member 51 is attached to the first arm portion 31b so as to be substantially movable back and forth at a first position (separation position) shown in FIG. 3 (a) and a second position (contact position) shown in FIG. 3 (b). ing. As shown in FIGS. 3 to 6, the moving member 51 has its front end 51 a bent to the outer peripheral side and locked to a substantially sector-shaped engaging groove 40 b formed in the first bail support member 40. . The intermediate portion 51 b extends along the first arm portion 31 b on the radially inner side from the rod 55.

  The rear end portion 51 c penetrates the guide groove 36 and protrudes inward to a position where it slightly overlaps the braking member 65 constituting the rotor braking mechanism 54. The width of the guide groove 36 is substantially the same as the diameter of the moving member 51. Therefore, the radially inner side of the intermediate portion 51 b of the moving member 51 is guided back and forth along the guide groove 36 in conjunction with the swinging of the bail arm 17. The outer peripheral side of the bent portion of the intermediate portion 51b and the rear end portion 51c is guided in the front-rear direction and the radial direction by the guide member 67. The guide member 67 is fixed to the first cover member 31c, and a concave groove 67a that is curved so that the rear end portion 51c is fitted is formed inside.

  The guide member 67 is formed with, for example, a cylindrical mounting hole 67b in which a pressing spring 68 made of a coil spring can be mounted and is opened in the concave groove 67a. The pressing spring 68 is mounted in the concave groove 67 a in a compressed state, and presses the intermediate portion 51 b of the moving member 51 to urge the rear end portion 51 c toward the braking member 65. A pressing member 69 in which a semicircular arc-shaped recess 69 a is formed so as to engage with the outer peripheral surface of the intermediate portion 51 b of the moving member 51 is attached to the tip of the pressing spring 68. The pressing member 69 is provided to allow the intermediate portion 51b of the moving member 51 to move forward and backward, and to efficiently transmit the urging force of the pressing spring 68 to the intermediate portion 51b.

  When the bail arm 17 is in the yarn releasing posture, the locking end of the moving member 51 in the engaging groove 40b is closer to the yarn winding posture than the line connecting the rear end portion 51c and the swing center of the bail arm 17. positioned. That is, the moving member 51 has a first position in the same direction from a line segment connecting the axis of the rear end 51c and the swing axis of the first bail support member 40 when in the contact position (FIG. 3B). It arrange | positions so that the latching position to the 1st bail support member 40 may exist in (separation position) and 2nd position (contact position). Thereby, when the rear end 51c of the moving member 51 is pressed by the switching member 52, the first bail support member 40 can be returned to the yarn winding posture side. When in the second position (contact position), the end surface of the rear end portion 51 c bites inward slightly from the outer peripheral surface on the back side from the front end surface of the braking member 65. For this reason, even if the moving amount of the moving member 51 slightly fluctuates, the same braking force can always be obtained.

  The switching member 52 is a member made of synthetic resin such as polyamide synthetic resin or polyacetal, for example. As shown in FIGS. 5 and 6, the switching member 52 is detachably attached to the flange portion 2 d at a split portion between the reel body 2 a and the lid member 2 b. It is attached to. A rectangular notch 53 is formed in a divided part of the reel body 2a and the lid member 2b. The switching member 52 includes a mountain-shaped cam portion 60 having two inclined surfaces 60 a and 60 b, a constricted portion 61 formed integrally with the cam portion 60, and a flange portion 62. The inclined surface 60a is an inclined surface that protrudes forward toward the rotor 3 on the downstream side in the yarn winding rotation direction of the rotor 3 indicated by an arrow in FIG. The inclined surface 60b is an inclined surface in which the protruding amount decreases from the protruding portion of the inclined surface 60a toward the downstream side in the yarn winding rotation direction. The protruding amount of the protruding end 60c that protrudes most on the inclined surfaces 60a and 60b is the toggle spring mechanism 50 when the moving member 51 whose rear end portion 51c contacts the inclined surface 60a presses the bail arm 17 toward the yarn winding posture. It is set to exceed the dead center.

  The constricted portion 61 has a size that can be fitted into the notch 53, and forms a gap between the cam portion 60 and the flange portion 62 that has substantially the same dimensions as the thickness of the flange portion 2 d. The flange portion 62 has a larger cross section than the constricted portion 61 and contacts the back surface of the flange portion 2d. When the inclined surface 60b is provided, when the bail arm 17 is in the yarn releasing posture, even if the reverse rotation (rotation in the yarn unwinding direction) is forcibly applied and the moving member 51 comes into contact with the switching member 52, the bail reversing mechanism 18 The moving member 51 is smoothly guided to the switching member 52 on the inclined surface 60b.

  The rotor braking mechanism 54 brakes the rotor 3 when the bail arm 17 swings in the yarn releasing posture, and is mounted on the moving member 51 and the mounting groove 2f formed on the base end side of the cylindrical portion 2e. And a braking member 65. That is, the moving member 51 constitutes the bale reversing mechanism 18 and also constitutes the rotor braking mechanism 54.

The braking member 65 is provided to brake the rotation of the rotor 3 when the bail arm 17 is in the yarn releasing posture. The braking member 65 is composed of two members, a first semi-circular brake member 65a and a second brake member 65b made of an elastic material. The first braking member 65a and the second braking member 65b are pressed against the circular mounting groove 2f by a spring member 66 mounted in an annular groove 65e formed on the outer periphery of the side portion. The braking member 65 includes a friction portion 65c that frictionally engages with the mounting groove 2f and a plurality of engagement portions 65d with which the rear end portion 51c of the moving member 51 engages. The engaging portion 65d is an engaging groove that is disposed on the outer periphery of the braking member 65 with a space therebetween and that engages with the rear end portion 51c. Further, the braking member 65 is formed with a plurality of tapered portions 65f inclined toward the engaging portion 65d at a plurality of locations. The tapered portion 65f is an inclined surface formed to guide the rear end portion 51c to the engaging portion 65d.

  As shown in FIG. 10 in an enlarged manner, the braking member 65 further includes an annular main body portion 65g that is mounted in the mounting groove 2f. A friction portion 65c is formed on the inner peripheral side of the main body portion 65g, and the front-rear length A of the friction portion 65c is shorter than the front-rear length B of the main body portion 65g. Therefore, a first gap 2g is formed between the front side wall surface 2i of the mounting groove 2f and the front end surface of the friction portion 65c, and between the rear side wall surface 2j of the mounting groove 2f and the rear end surface of the friction portion 65c. A second gap 2h is formed. The front-rear length of the first gap 2g is longer than the front-rear length of the second gap 2h. The front-rear length B of the main body 65g is substantially the same as the front-rear length of the mounting groove 2f. Therefore, the front-rear length A of the friction part 65c is shorter than the front-rear length of the mounting groove 2f.

  Further, as shown in FIG. 10, the main body portion 65g has a first annular portion 65h formed on the front side and a second annular portion 65i formed on the rear side with a larger diameter than the first annular portion 65h. ing. The first annular portion 65h has a front portion of the friction portion 65c on the inner peripheral side, and the second annular portion 65i has a rear portion of the friction portion 65c on the inner peripheral side. A plurality of engaging portions 65d are formed on the outer peripheral side of the second annular portion 65i, and an annular groove 65e is formed on the outer peripheral side of the second annular portion 65i located outside the friction portion 65c. Further, the second annular portion 65i is formed with a protruding portion 65j that protrudes rearward from the mounting groove mounting groove. The protruding portion 65j extends to the rear end side of the cylindrical portion 2e, and the tip portion thereof is disposed so as not to contact the flange portion 2d.

  The spring member 66 is an arc-shaped wire-like member that is attached to an annular groove 65e formed on the outer periphery of the second annular portion 65i side of the braking member 65, and has an elastic force that biases inward. . The spring member 66 has an opening between both ends for mounting on the braking member 65, and one end is bent and locked in the radial direction to prevent the spring member 66 from coming off from the annular groove 65e.

  The restricting mechanism 75 is provided at a facing portion between the bail arm 17 and the first arm portion 31b of the rotor 3, and when the bail arm 17 is disposed in the yarn releasing posture, the bail arm 17 returns to the yarn winding posture. This is a mechanism for releasing the restriction until the rear end portion 51c of the moving member 51 reaches the protruding end 60c of the inclined surface 60a when the bail arm 17 swings to the yarn winding posture. As shown in FIGS. 7 and 8, the restriction mechanism 75 includes a restriction pin 76 attached to the attachment hole 37 of the first arm portion 31b, a coil spring 77 that urges the restriction pin 76 toward the bail arm 17, and And a pressing portion 78 provided on the first bail support member 40.

  The restriction pin 76 is a metal pin having a large diameter contact portion 76a and a small diameter spring mounting portion 76b. The tip of the coil spring 77 is in contact with the step portion between the contact portion 76a and the spring mounting portion 76b. The coil spring 77 is disposed on the outer peripheral side of the spring mounting portion 76 b and biases the restriction pin 76 toward the first bail support member 40. The pressing portion 78 has two inclined surfaces 78a and 78b, and is formed to protrude toward the first arm portion 31b. When the pressing portion 78 swings from the yarn release posture to the yarn winding posture, the restriction can be released by passing the restriction pin 76 until the rear end portion 51c of the moving member 51 reaches the protruding end 60c of the inclined surface 60a. Placed in position. Specifically, as shown in FIG. 9A, the pressing portion 78 is positioned on the upstream side of the swinging direction from the regulating pin 76 to the yarn winding posture indicated by the arrow when the yarn is released, as shown in FIG. As shown in b), the toggle spring mechanism 50 is disposed at such a position as to pass through the regulation pin 76 before reaching the dead point during swinging to the yarn winding posture.

  In the bail reversing mechanism 18 having such a configuration, the toggle spring mechanism 50 can take a first position as shown in FIG. 3A and a second position as shown in FIG. is there. The first position corresponds to the yarn winding posture of the bail arm 17, and the second position corresponds to the yarn releasing posture of the bail arm 17. The rear end 51c of the moving member 51 is guided by the guide groove 36 at the first position (separation position) shown in FIG. 3A and the second position (contact position) shown in FIG. Can move back and forth. The first position (separation position) corresponds to the yarn winding posture, and the second position (contact position) corresponds to the yarn winding posture. In the second position (contact position), the rear end portion 51 c of the moving member 51 is engaged with the engaging portion 65 d of the braking member 65. At this time, in the rotor braking device 54, when the braking member 65 rotates together with the rotor 3, the friction portion 65c is frictionally engaged with the mounting groove 2f, so that the rotor 3 is braked.

  When the rotor 3 is rotated in the yarn winding direction by the operation of the handle 1 at the second position (contact position), the rear end portion 51c of the moving member 51 collides with the inclined surface 60a of the switching member 52 and rotates. 51 is pressed forward toward the first position (separation position), and when the dead point of the toggle spring mechanism 50 is exceeded, the bail arm 17 returns to the yarn winding posture. At this time, the restriction by the restriction pin 76 of the restriction mechanism 75 is released before the dead point of the toggle spring mechanism 50 is exceeded.

  As shown in FIG. 2, a reverse rotation prevention mechanism 70 for prohibiting and releasing the reverse rotation of the rotor 3 is disposed inside the cylindrical portion 30 of the rotor 3. The reverse rotation prevention mechanism 70 has a roller-type one-way clutch, and the reverse rotation of the rotor 3 is prohibited or released by switching the one-way clutch between the operating state and the non-operating state.

  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 71. The spool 4 includes a bobbin trunk 4a around which the fishing line is wound, a skirt 4b formed integrally with the rear part of the bobbin trunk 4a, and a flange 4c formed integrally with the front end of the bobbin trunk 4a. Have.

  Next, the operation and operation of the reel will be described in detail.

  At the time of casting, the reverse rotation preventing mechanism 70 makes the rotor 3 in a reverse rotation prohibition state, and holds the bail arm by hand to reverse the bail arm 17 to the yarn releasing posture. When the bail arm 17 is reversed to the yarn releasing posture, the first bail support member 40 and the second bale support member 42 are tilted backward, and the bale reversing mechanism 18 is in the second position as shown in FIG. Be placed. At this time, in the restriction mechanism 75, when the dead point of the toggle spring mechanism 50 is exceeded, the pressing portion 78 passes through the restriction pin 76. In a state where the bail arm 17 falls to the line releasing posture, the fishing line from the spool 4 can be easily fed out.

  In the swing from the yarn winding posture to the yarn releasing posture, in the toggle spring mechanism 50, the rod 55 swings counterclockwise while gradually retracting in FIG. 3 (a) by the rotation of the first bail support member 40. Then, the second position shown in FIG. At this time, retreat until the dead point is exceeded. When the dead point is exceeded, the rod 55 is advanced by the urging force of the coil spring 57, and the bail arm 17 is switched to the yarn releasing posture side and held in that posture. When the dead point is exceeded, the pressing portion 78 of the restricting mechanism 75 gets over the restricting pin 76 and restricts the swinging of the bail arm 17 to the yarn winding posture, and at the time when the pressing portion 78 passes the restricting pin 76 The pin 76 suddenly collides with the first bail support member 40 to produce sound.

  When the bail arm 17 swings to the yarn releasing posture, the rear end portion 51c of the moving member 51 is engaged with the engaging portion 65d of the braking member 65 along with this swinging. When the braking member 65 rotates together with the rotor 3, the friction portion 65c is frictionally engaged with the mounting groove 2f, so that the rotor 3 is braked.

  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. At this time, as described above, the bail arm 17 is regulated by the regulation mechanism 75 and is difficult to return from the yarn releasing posture to the yarn winding posture.

  After the casting, when the handle 1 is rotated in the yarn winding direction while the bail arm 17 is maintained in the yarn releasing posture, the rotor 3 is rotated in the yarn winding direction by the rotor drive mechanism 5. When the rotor 3 rotates in the yarn winding direction, the bail arm 17 returns to the yarn winding posture by the bale reversing mechanism 18.

  In such a rotor braking device 54, when the bail arm 17 swings from the yarn winding posture to the yarn releasing posture, the rear end portion 51c of the moving member 51 provided on the rotor 3 is engaged with the engaging portion 65d of the braking member 65. When the braking member 65 rotates together with the rotor 3, the friction part 65c is frictionally engaged with the mounting groove 2f, so that the rotor 3 is braked. Here, the friction portion 65c is frictionally engaged with the mounting groove 2f so as to be rotatable, so that the braking force is not limited to a part as in the prior art but is evenly applied to the whole part, so that the braking force is stabilized. Can do.

  Further, in this rotor braking device 54, the longitudinal length A of the friction portion 65c is shorter than the longitudinal length B of the main body portion 65g, so that the entire inner peripheral surface of the braking member 65 contacts the mounting groove 2f. There is no. Therefore, the contact area of the friction portion 65c with the mounting groove 2f decreases, so that the pressure per unit area increases and the influence of the pressure change amount can be reduced, so that the braking force can be stabilized. Furthermore, even if the braking member 65 is distorted due to an error in the manufacturing process or the like, the entire friction portion 65c can be reliably brought into contact with the mounting groove 2f by the spring member 66, so that the braking force can be further stabilized.
