Description

  The present invention relates to a fishing spinning reel provided with a reverse rotation prevention device for preventing reverse rotation of a rotor that rotates in conjunction with a handle operation.

  In general, a spinning reel for fishing equipped with a reverse rotation prevention device that prevents reverse rotation of a rotor that rotates in conjunction with handle operation, for example, when a fishing line is wound up while preventing reverse rotation of the rotor, for example, By pulling, an excessive tensile force may be applied to the fishing line and the fishing line may be cut, or the locking part and the supporting part of the reverse rotation preventing device may be damaged by a sudden impact force.

In order to absorb the shock given to the fishing line or the reverse rotation prevention mechanism by such an excessive tension action, the ratchet is supported rotatably on the rotor as a reverse rotation prevention member that is prevented from rotating by the operation of the rotation prevention means. A spinning reel is known in which a shock absorber is provided between a rotor and a ratchet (see, for example, Patent Document 1).
JP 60-30632 A

  However, in this conventional spinning reel, a ratchet is provided on the outer periphery of the cylindrical portion that supports the rotor or the pinion shaft through which the spool shaft is inserted, and one end of a coiled spring attached to the outer periphery of the cylindrical portion that supports the rotor is provided. Since the shock absorber is formed by supporting it with the rotor and supporting the other end with a ratchet, it is impossible to absorb a large impact force when the rotor rotates in reverse because of the moment or torque acting.

Further, when the rotation of the rotor is prevented, that is, when the ratchet is prevented from rotating by the rotation preventing means and the coiled spring as the shock absorber is completely tightened, the rotor and the ratchet are connected to the respective ends of the coiled spring. Since they are connected via the parts, the support area for transmitting the force is extremely small, the support strength is insufficient, and the durability is poor. Further, even when a restricting means for restricting the rotation range is provided between the ratchet and the rotor, this restricting means is protruded from the rotor side to a protrusion protruding from the side surface of the ratchet separately from the shock absorber. The support area for transmitting force is extremely small, sufficient support strength is not obtained, and durability is inferior.

  The present invention has been made based on such circumstances, and has a small and lightweight structure for preventing reverse rotation that can absorb a large impact force at the time of reverse rotation of the rotor and can obtain stable shock absorption performance over a long period of time. An object of the present invention is to provide a fishing spinning reel provided.

The fishing spinning reel of the present invention that achieves the above object includes a reverse rotation prevention device that prevents reverse rotation of a rotor that rotates about a rotation support shaft in conjunction with a handle operation. A spinning reel for fishing that alleviates the impact force associated with the feeding of the fishing line through the fishing line guide, wherein the anti-reverse device is attached to the inner circumferential part of the cylindrical part of the rotor. And a blocking member that engages with the anti-reverse body and prevents the reverse-rotation body from moving in the reverse direction when the rotor rotates in the reverse direction. And a resilient member that is interposed between the anti-reverse body and the rotor and absorbs an impact force acting on the anti-reverse body when the reverse rotation of the rotor is prevented, and the anti-reverse body comprises the rotor Cylinder A ring-shaped portion extending along the portion and an engaging protrusion protruding from the end of the ring-shaped portion, and the engaging protrusion of the reverse rotation preventing body is interposed between the rotor and the reverse rotation preventing body. The protective ring is housed in the dome formed in the protective annular body together with the elastic member, and is brought into contact with the end wall portion of the dome by the urging force of the elastic member. And forming one assembling unit .

In the spinning reel for fishing according to the present invention, the reverse rotation preventing body that engages with the blocking member is supported on the inner peripheral portion of the cylindrical portion of the rotor so as to be rotatable by a predetermined angle, and the impact is absorbed by the resilient member. At the position where the anti-reverse body is greatly spaced radially outward from the rotation support shaft, the impact when the rotor is prevented from reversing is absorbed. large impact force can be absorbed, since the reverse rotation preventing member may be supported in a stable state, it is possible to obtain a stable shock absorbing performance over a long period of time, further, the reverse rotation preventing a protective annulus By forming one assembly unit with the body and the elastic member, the assembling work is extremely simple, and the contact of the reverse rotation prevention body and the elastic member with the rotor is prevented, thereby improving the durability. Can.

1 to 6 show a fishing spinning reel 10 according to a preferred embodiment of the present invention.
As shown in FIG. 1 as a whole, the fishing spinning reel 10 of the present embodiment has a reel body 12 and a reel mounting leg portion 14 extending from the reel body 12. At the end, a rod attachment portion 14a attached to a fishing rod (not shown) is formed. A handle shaft 16 is rotatably supported in the reel body 12 via a ball bearing (not shown), and a handle 18 is attached to an end of the handle shaft 16. A drive gear 22 that forms a part of the drive mechanism 20 is disposed at a portion of the handle shaft 16 disposed in the reel body 12.

The drive gear 22 is engaged with a pinion gear 26 that extends in a direction orthogonal to the handle shaft 16 and is rotatably supported in the cylindrical projection 12a of the reel body 12 via bearings 24a and 24b. ing. The pinion gear 26 is formed at the proximal end portion of the rotating shaft cylinder 28 having a cylindrical structure, and a shaft cylinder portion 32 that is a rotation support shaft of the rotor 30 rotates at a distal end portion opposite to the pinion gear 26. The rotating shaft 28 is integrally fixed by a nut 34. The tightening force of the nut 34 is supported by the cylindrical protrusion 12a of the reel body 12 from the shaft tube portion 32 through a pair of bearings 24a and 24b with the spacer 23 interposed therebetween. A pair of arm portions 36 project from a radially opposing portion of the base end portion of the rotor 30, and the arm portions 36 extend in the axial direction from the base end portion of the rotor 30 toward the tip end side. The bail 38 is attached to the front end portion so as to be reversible. One end of the bail 38 is attached to a fishing line guide (not shown) provided on the handle 18 side.

  A spool shaft 40 is slidably supported in the pinion gear 26 and the rotating shaft cylinder 28, and is operated by the handle shaft 16 via the drive gear 22 and the pinion gear 26 described above. The rating mechanism 42 can be driven to reciprocate with a constant stroke along the axial direction. A spool 44 having a winding body portion 44 a around which a fishing line is wound and a skirt portion 44 b in which the rotor 30 is disposed is detachably attached to the tip end of the spool shaft 40, and the handle shaft 16 together with the spool shaft 40. Can be reciprocated in a direction perpendicular to.

  In the fishing spinning reel 10, when the handle 18 is rotated to rotate the handle shaft 16, the spool 44 reciprocates back and forth with a constant stroke via the oscillating mechanism 42 and the spool shaft 40, and at the same time, the drive gear The rotor 30 rotates via the 22 and the pinion gear 26. As a result, the fishing line is evenly wound around the winding body 44 a of the spool 44 through the fishing line guide that rotates together with the rotor 30.

  As shown in an enlarged view in FIGS. 2 to 6, the rotor 30 of this embodiment includes a cylindrical portion 46 that surrounds the above-described shaft tube portion 32, a tip portion of the shaft tube portion 32, and an intermediate portion of the cylinder portion 46. The cylindrical portion 46 has both ends on the reel body 12 side and the spool 40 side opened outward in the axial direction. In the cylindrical portion 46, the reel body 12 side protrudes from the shaft cylinder portion 32 to surround the cylindrical protrusion 12 a of the reel body 12, and the spool 44 side protrudes from the rotating shaft cylinder 28 to accommodate the nut 34 therein. The cylindrical portion 46 is formed longer than the stroke length of the spool 44, and the inside of the cylindrical portion 46 is not exposed from the skirt portion 44b when the spool 44 reciprocates.

  In the rotor 30, there is provided a reverse rotation preventing device 50 for preventing the rotation in the reverse rotation direction indicated by the solid arrow R in FIG. The reverse rotation preventing device 50 according to the present embodiment is configured such that when the rotor 30 rotates in the reverse rotation direction R, the reverse rotation prevention body 52 having an annular structure supported so as to be rotatable by a predetermined angle along the inner periphery of the cylindrical portion 46. A blocking member 54 that engages with the prevention body 52 and prevents the reverse rotation prevention body 52 from moving in the reverse rotation direction R, and is interposed between the reverse rotation prevention body 52 and the rotor 30 to block the reverse rotation of the rotor 30. Sometimes, the rotor 30 is formed of a resilient member 56 that absorbs the impact force applied to the anti-reverse body 52.

  As shown in FIGS. 2, 3, 5, and 6, the disk-like portion 48 of the rotor 30 has three notches 49 extending in an arc shape along the inner peripheral surface of the cylindrical portion 46. The same length along the direction is formed at equal intervals in the radial direction and the circumferential direction. On the other hand, the reverse rotation preventing body 52 supported by the rotor 30 is separated from the ring-shaped portion 58 along the inner peripheral surface of the cylindrical portion 46 from the end of the ring-shaped portion 58 at positions spaced apart from each other at equal intervals in the circumferential direction. It has an engaging protrusion 60 protruding to the spool 44 side, and this engaging protrusion 60 is mounted in a state of protruding into the notch 49 from the reel body 12 side. A protective annular body 62 made of, for example, synthetic resin is inserted between the rotor 30 and the reverse rotation prevention body 52, and direct contact between the rotor 30, the reverse rotation prevention body 52, and the elastic member 56 is prevented. ing. Thereby, generation | occurrence | production of the electric corrosion etc. by the contact of the dissimilar metal between the rotor 30, the reverse rotation prevention body 52, and the elastic member 56 can be prevented, and also the improvement of sliding property can be aimed at.

  The ring-shaped portion 58 of the reverse rotation preventing body 52 is formed with a base portion 58a that is thick in the radial direction and supported by the disk-shaped portion 48, and a step portion is formed with respect to the base portion 58a and is locked to the inner peripheral surface thereof. And a retaining plate 64 screwed to the disk-like portion 48 through a step formed between the base portion 58a and the tooth portion 58b. It is immovable in the direction and is held so as to be rotatable.

  The protective annular body 62 held by the retaining plate 64 together with the anti-reverse body 52 includes a peripheral wall portion 62a interposed between the ring-shaped portion 58 and the cylindrical portion 46 of the rotor 30, and a base portion 58a of the ring-shaped portion 58. And the flat plate portion 62b inserted between the disk-like portion 48 of the rotor 30 and the ring-like portion 58 of the anti-reverse body 52 together with the flat plate portion 62b inserted into the notch portion 49 of the rotor 30. And a dome portion 62c that defines a housing space. The flat plate portion 62b is disposed so as to overlap the base portion 58a of the ring-shaped portion 58 between the adjacent dome portions 62c, and does not protrude radially inward beyond the base portion 58a. Further, each dome portion 62c has a top wall portion on the spool 44 side of two arc-shaped peripheral wall portions 61a and two flat end wall portions 61b (see FIGS. 3 and 5) that abut against the wall surface of the notch portion 49. Closed at 61c (see FIGS. 2 and 5) and opened on the reel body 12 side, it extends in an arc shape corresponding to the above-mentioned notch 49, and the end of the side wall facing this opening has a notch 49 A locking edge 62d that contacts the disk-shaped portion 48 is formed along the peripheral edge of the disk.

  When the anti-reverse body 52 and the protective annular body 62 are mounted on the rotor 30, the engagement protrusions 60 of the anti-reverse body 52 and the present embodiment are provided in the respective dome parts 62 c of the protective annular body 62. In the embodiment, a resilient member 56 formed of a compression coil spring of the same size is inserted, and one end of this resilient member 56 is supported by an end wall portion 61b positioned in the forward direction in the reverse rotation direction R (see FIG. 4). The end is supported by the side surface of the engaging protrusion 60. Due to the urging force of the elastic member 56, the reverse rotation preventing body 52 brings the engaging protrusion 60 into contact with the other end wall portion 61b of the dome portion 62c. As a result, the protective annular body 62, the reverse rotation preventing body 52, and the elastic member 56 form one assembly unit. In this unit, each dome portion 62c is arranged on the outer peripheral portion of the protective annular body 62, so that the widest space is secured when the elastic member 56 and the reverse rotation preventing body 52 are assembled, and the coil spring is used. Since the formed elastic member 56 can be mounted in the dome portion 62c along the peripheral wall portion 62a, the attaching operation is extremely simple.

  Thus, after the reverse rotation preventing body 52 and the elastic member 56 are assembled in the protective annular body 62 to form a unit structure, each dome portion 62c is inserted into the cutout portion 49 of the disk-shaped portion 48, and the reverse rotation preventing body. The retaining plate 64 holds the rotor 30 through a step formed on the inner peripheral portion of the ring-shaped portion 58 of 52. The protective annular body 62 is prevented from rotating with respect to the rotor 30 by fitting the dome part 62c to the notch part 49, and the flat plate part 62b is sandwiched between the disk-like part 48 and the ring-like part 58, The retaining edge 62d is held between the disc-shaped portion 48 and the retaining plate 64, thereby preventing axial movement. On the other hand, since the reverse rotation prevention body 52 is only held in contact between the protective annular body 62 and the retaining plate 64, the engagement protrusion 60 in the dome portion 62 c causes the elastic member 56 to move. It can rotate with respect to the rotor 30 while compressing. In this embodiment, as shown in FIGS. 2 and 6, an O-ring-shaped friction member 66 (rubber material) is disposed in an annular groove 58c formed on the outer peripheral surface of the reverse rotation preventing body 52, and the reverse rotation preventing body. 52 and the protective annular body 62 are formed in a structure capable of forming a frictional force.

  As shown in FIGS. 2 and 4, the blocking member 54 that prevents the reverse rotation preventing body 52 from rotating in the reverse rotation direction R is a portion facing the locking tooth 59 formed in the tooth portion 58 b, and the proximal end portion Is rotatably held by a support shaft 68 provided on the end surface of the cylindrical projection 12a of the reel body 12, and the locking claw 54a at the tip is engaged with the locking teeth 59 toward the rear in the reverse rotation direction R. Extends like a lever to the mating position. The operation pin 69 protrudes from an intermediate position of the blocking member 54, is inserted into a long hole 72 formed in the friction plate 70, and can move while being guided by the long hole 72.

  The friction plate 70 is held by elastically frictionally engaging a base portion 74 formed in a C shape with the peripheral portion of the shaft tube portion 32, and is provided with a stopper pin 76 that protrudes from the tubular protrusion 12 a. The movement range is specified. That is, when the rotor 30 rotates in the reverse rotation direction R, the shaft tube portion 32 and the cylindrical portion 46 move in the reverse rotation direction R, and the friction plate 70 moves in the reverse rotation direction R together with the shaft tube portion 32. As a result, the friction plate 70 moves the blocking member 54 via the elongated hole 72 and the operating pin 69, and engages the locking claw 54 a with the locking tooth 59. Thereby, the reverse rotation preventing body 52 in which the locking teeth 59 are formed is prevented from rotating in the reverse rotation direction R by the cylindrical protrusion 12 a of the reel body 12 via the blocking member 54. On the contrary, when the rotor 30 is rotated by the handle 18 in the forward rotation direction F (fishing line winding direction) indicated by a dotted line in FIG. 4, the friction plate 70 is rotated together with the shaft tube portion 32 in the clockwise direction. After the blocking member 54 is rotated in a direction in which the claw 54 a is separated from the locking tooth 59, the claw 54 a is locked by the stopper pin 76. As a result, the blocking member 54 is held at the position indicated by the two-dot chain line in FIG. When the engagement between the blocking member 54 and the locking teeth 59 is released, the rotor 30 can rotate in the forward rotation direction F without being blocked by the blocking member 54.

  In this fishing spinning reel 10, a blocking member 54 is disposed at a position indicated by a two-dot chain line in FIG. 4 so that the rotor 30 can be rotated forward and backward, and a blocking member 54 is disposed at a position indicated by a solid line. A switching cam 78 is provided for switching between normal rotation and non-reverse rotation, and switching operation of the switching cam 78 is performed by a switching lever provided on the rear end wall of the reel body 12 as shown in FIG. 80. When the switching lever 80 is disposed at the reverse rotation prevention position, the blocking member 54 is disposed at a position indicated by a solid line in FIG. When the reverse rotation prevention position is switched to the forward / reverse rotation possible position, the blocking member 54 is disposed at a position indicated by a two-dot chain line by the switching cam 78, and the rotor 30 is moved in either the reverse rotation direction R or the forward rotation direction F. It can rotate freely.

When the blocking member 54 is in the reverse rotation prevention position indicated by the solid line in FIG. 4, the reverse rotation prevention device 50 formed in this way moves the rotor 30 in the reverse rotation direction R around the shaft cylinder portion 32 by, for example, fish pulling. When a force to rotate is applied abruptly, the sudden force acts on the rotor 30 via a pair of arms 36 (FIG. 1) to rotate the rotor 30 in the reverse rotation direction R, pay out a fishing line. At this time, the anti-reverse device 50 provided on the rotor 30 prevents the anti-reverse body 52 from rotating with respect to the reel body 12 by the locking teeth 59 and the blocking member 54 engaged therewith. On the other hand, the rotor 30 and the protective annular body 62 rotate in the reverse rotation direction, and compress the elastic member 56 with the engaging protrusion 60 . Thereby, the big impact force accompanying the feeding of the fishing line through the fishing line guide part is relieved. When each elastic member 56 is completely compressed, the disk-like portion 48 of the rotor 30 and the engaging protrusion 60 of the reverse rotation preventing body 52 are connected via the compressed elastic member 56, and the rotor 30. Reversal is prevented. Since the force in the reverse rotation direction R acting on the rotor 30 acts on the plurality of engaging protrusions 60 from the disk-like portion 48 via the plurality of resilient members 56, the support area for transmitting the force is extremely large, Support strength is extremely high. Since the rotor 30 rotates in the reverse rotation direction R when a magnitude exceeding the frictional force between the friction member 66 and the protective annular body 62 is applied, the friction member 66 and the protective annular body 62 are rotated. The impact force is also reduced by the frictional force between the two.

  According to the fishing spinning reel 10, the reverse rotation preventing body 52 that engages with the blocking member 54 via the locking teeth 59 is supported on the inner peripheral portion of the cylindrical portion 46 of the rotor 30 so as to be rotatable by a predetermined angle. When the impact is absorbed by the member 56, the reversal prevention body 52 absorbs the impact when the rotor 30 rotates in the reverse direction at a position where the reversal prevention body 52 is largely spaced radially outward from the shaft cylinder portion 32. A large impact force during reverse rotation of the rotor 30 can be absorbed without increasing the size or weight. Further, since the reverse rotation preventing body 52 can be supported in a stable state, stable shock absorbing performance can be obtained over a long period of time.

  Further, when the elastic member 56 is formed of a spring and absorbs an impact force acting in the circumferential direction between the reverse rotation preventing body 52 and the rotor 30, the shaft member 32, which is a rotation support shaft, is used. A large installation space can be secured while being far away from each other, and the elastic member 56 can be easily and efficiently assembled and disassembled.

  Further, by attaching the reverse rotation preventing body 52 and the elastic member 56 to the rotor 30 via the protective annular body 62, the reverse rotation preventing body 52 and the elastic member 56 come into contact with the rotor 30 and wear. Further, by preventing electrolytic corrosion due to contact of such different metals, the durability can be greatly improved.

  The resilient member 56 that absorbs such an impact replaces the spring in the above-described embodiment, and uses a pair of magnets 86 as shown in FIG. Alternatively, as shown in FIG. 8, it may be formed of a block-like rubber member 96.

  In the above-described embodiment or modification, the three dome parts 62c are arranged at equal intervals along the circumferential direction, and the elastic member 56 is arranged on each of them. However, such dome parts 62c have two or four dome parts 62c. In this case, a notch 49 corresponding to the disk-like portion 48 of the rotor 30 is formed.
