Description

  The present invention relates to a braking operation structure, and more particularly, to a fishing reel spool operating structure that is attached to a reel body of a fishing reel and is operated by adjusting a braking force of the spool.

  2. Description of the Related Art Conventional fishing reels have widely adopted a braking operation structure that adjusts various mechanisms built into the reel body by a turning operation to change the braking force of the spool. Such a brake operation structure includes, for example, one that adjusts the drag force of the rear drag mechanism of the rear drag type spinning reel.

  A braking operation structure used in a conventional spinning reel rear drag mechanism includes a mounting portion, an operation knob, a sound output member, and a fixing bolt. The mounting portion is formed to protrude cylindrically at the rear portion of the reel body, and has a male screw portion on the outer periphery. The operation knob is formed in a cylindrical shape with a bottom so that the mounting portion can be accommodated, and has an internal thread portion on the inner periphery. The female screw portion can be screwed into the male screw portion of the mounting portion. The operation knob includes a pressing member, and this pressing member is disposed at the rear portion of the rear drag mechanism on the inner peripheral portion of the mounting portion. The pressing member includes a cylindrical pressing portion and a protruding portion protruding in a cylindrical shape from the pressing portion. The pressing portion is disposed on the rear drag mechanism side and is a portion that presses the rear drag mechanism. The protruding portion is formed with a smaller diameter than the pressing portion, and is disposed on the operation knob side and attached to the operation knob. Concavities and convexities are formed at predetermined intervals on the outer periphery of the protruding portion.

  The sound emitting member is, for example, a semicircular spring member, and both end portions penetrate the mounting portion from the outer peripheral side to the inner peripheral side. Both end portions of the sound emitting member are engaged with irregularities formed on the outer periphery of the protruding portion of the pressing member at the inner peripheral portion of the mounting portion. Moreover, the both ends of the sound output member can be engaged with the rear portion of the pressing portion of the pressing member, thereby restricting the rearward release of the pressing member. The fixing bolt penetrates the bottom of the operation knob from the outside on the bottom side of the operation knob and fixes the pressing member to the operation knob.

In the conventional braking operation structure, first, a pressing member is mounted on the rear part of the rear drag mechanism assembled to the reel body. Next, the sound output member is mounted on the mounting portion, and both ends of the sound output member are engaged with the unevenness of the protruding portion of the pressing member behind the pressing portion of the pressing member. Finally, the operation knob is mounted while being screwed to the mounting portion, and is fixed to the pressing member using a fixing bolt. In the braking operation structure assembled in this way, when the operation knob is rotated, both end portions of the sound output member repeatedly collide with the unevenness of the pressing member to generate a click sound. At this time, the pressing member fixed to the operation knob with the fixing bolt presses or releases the rear drag mechanism, and the drag force of the rear drag mechanism is adjusted. Here, if the operation knob is continuously rotated in the direction to release the pressing of the rear drag mechanism, the pressing member moves rearward together with the operation knob, and eventually the pressing portion rear portion of the pressing member is located at both ends of the sound output member. Abutted and locked. In this way, the operation knob including the pressing member is prevented from falling off the mounting portion.

  In the conventional braking operation structure, when the operation knob is rotated in the direction to release the pressing of the rear drag mechanism, the rear portion of the pressing portion of the pressing member is prevented so that the operation knob including the pressing member does not fall out of the mounting portion. The both ends of the sound emitting member are brought into contact with and locked. However, if the operation knob is further rotated in the direction in which the rear drag mechanism is released in a state where the rear portion of the pressing member is in contact with both ends of the sound output member, the female screw portion of the operation knob and the mounting thereof are attached. There is a risk that the degree of wear of the male thread portion of the portion will increase. Further, depending on the situation, there is a risk that the threads of the internal thread portion of the operation knob and the external thread portion of the mounting portion may be damaged. Then, it becomes difficult to rotate the operation knob stably.

  On the other hand, in the conventional braking operation structure, the operation knob is screwed into the mounting portion. And the fixing bolt penetrates the bottom part of the operation knob from the bottom part side outer side of the operation knob, and fixes the pressing member to the operation knob. When the pressing member is fixed to the operation knob using the fixing bolt in this way, the bolt head appears on the outer surface of the bottom of the operation knob, and thus the appearance of the operation knob may be impaired.

  As shown in FIG. 1, the reel body 1 a has a rotor driving mechanism 7 for rotating the rotor 2, and the spool 3 is moved in the front-rear direction along the rotation axis of the rotor 2. And a level wind mechanism 8 for winding up the fishing line uniformly.

  The rotor drive mechanism 7 has a master gear 11 that rotates together with the handle shaft 10 a and a pinion gear 12 that meshes with the master gear 11. The pinion gear 12 is formed in a cylindrical shape, and a front portion thereof extends through the center portion of the rotor 2 to the spool 3 side. The pinion gear 12 is rotatably supported by bearings 13a and 13b supported by the body 1a. The spool shaft 14 passes through the center portion of the pinion gear 12 so as to be movable in the front-rear direction along the rotation axis. The spool 3 is mounted at the tip of the spool shaft 14 so as not to rotate. A predetermined gap is secured between the inner diameter and the outer diameter of the spool shaft 14 at the center of the pinion gear 12.

  The level wind mechanism 8 is a mechanism that moves the spool shaft 14 in the front-rear direction by rotating the handle shaft 10 a by the handle 10. The level wind mechanism 8 includes a screw shaft 15 disposed on the lower back side of the spool shaft 14, a slider 16 that moves in the front-rear direction along the screw shaft 15, and a guide shaft disposed below the screw shaft 15 (see FIG. And an intermediate gear (not shown) that is fixed to the tip of the screw shaft 15 and meshes with the pinion gear 12. The screw shaft 15 and the guide shaft are disposed in parallel with the spool shaft 14.

  As shown in FIGS. 2 and 3, the rear lag mechanism 9 includes a cylindrical bush 18, a friction engagement portion 19 including friction plates 19a, 19b, and 19c arranged in three front and rear sides, and friction The engaging portion 19 includes a coil spring 21 for pressing the friction plates 19a, 19b, and 19c, and a pressing member 22 that presses the coil spring 21.

  The bush 18 is mounted on the outer periphery of the rear portion of the spool shaft 14 so as not to rotate but to move in the axial direction. On the central outer peripheral surface of the bush 18, an uneven portion 18a and a flange portion 18b formed side by side in the circumferential direction for sound output are arranged side by side in the front-rear direction. A chamfered portion 18 c is formed on the outer peripheral surface of the rear portion of the bush 18. In addition, a long hole portion 18 d that is rotatably mounted on a chamfered portion 14 a formed at the rear end portion of the spool shaft 14 is formed on the inner peripheral portion of the bush 18. The tip of the leaf spring 20 attached to the reel body 1a is in contact with the uneven portion 18a. Thereby, when the bush 18 rotates together with the spool shaft 14 during the drag operation, the leaf spring 20 vibrates and generates sound.

  The friction plates 19a are drag washers, and a total of three friction plates 19a are arranged from the rear portion of the flange portion 18b. The friction plate 19b is a washer with an ear whose outer peripheral portion is locked in the locking groove 1e and is non-rotatably engaged with the mounting tube portion 1c and cannot rotate with respect to the mounting tube portion 1c. Two pieces are attached to the end. The friction plate 19c is a key washer that is non-rotatably mounted on the bush 18 by the chamfered portion 18c, and is mounted fourth from the front. In addition, the number and shape of the friction plates 19a, 19b, and 19c of the friction engagement portion 19 are examples, and are not limited to the present embodiment. One end of a coil spring 21 disposed at the rear portion of the friction engagement portion 19 is in contact with the rear surface of the friction plate 19a.

  The pressing member 22 has a large-diameter flange portion 22a having a recessed front surface so that the other end of the coil spring 21 can be locked at the front end portion. Further, an uneven portion 22b arranged in the circumferential direction for sound output is formed on the central outer peripheral surface of the pressing member 22. A connecting portion 22c protruding in the radial direction in an X shape is formed on the outer peripheral surface of the rear end. A spring member 24 mounted on the mounting cylinder portion 1c is in contact with the uneven portion 22b. On the outer peripheral surface of the flange portion 2a of the pressing member 22, a male screw portion 22d that is screwed into the female screw portion 1d of the mounting cylinder portion 1c is formed.

  The spring member 24 is formed by bending an elastic wire into a semicircular shape, and a pair of projecting portions 24a bent so as to project inward are formed at both ends of the semicircle. The spring member 24 is mounted in an annular mounting groove 25 formed in the mounting cylinder portion 1c. Two through portions 25a are formed in the annular mounting groove 25, and the projecting portion 24a passes through the through portion 25a and contacts the concavo-convex portion 22b. The spring member 24 has a function of generating a sound during the drag operation and a function of preventing the pressing member 22 from coming off. That is, the protruding portion 24a contacts the back side of the flange portion 2a to prevent the pressing member 22 from coming off from the inner peripheral portion of the mounting cylinder portion 1c.

  As shown in FIGS. 2 and 3, the braking operation structure 6 includes the mounting cylinder portion 1 c provided at the rear portion of the reel body 1 a of the reel body 1, an operation knob 27 for adjusting the braking force of the spool 3, and The screw member 28 is fixed to the operation knob 27 by screwing.

  The mounting cylinder portion 1c is a cylindrical member formed integrally with the reel body 1a, and has the retaining groove 26 and the annular mounting groove 25 arranged side by side as described above on the outer peripheral surface. Moreover, the mounting cylinder part 1c has the internal thread part 1d in the inner peripheral surface.

  The operation knob 27 is formed in a bottomed cylindrical shape whose rear end is slightly reduced in diameter so that the mounting cylinder portion 1c can be accommodated, and the braking force of the spool 3 can be adjusted by a turning operation. A female screw portion 27 a is formed on the distal end side of the inner peripheral surface of the operation knob 27. An engagement recess 27 b that protrudes toward the pressing member 22 is formed on the bottom surface of the operation knob 27. The engaging recess 27b engages with the connecting portion 22c so as not to rotate but to move in the axial direction. Accordingly, when the operation knob 27 is rotated, the pressing member 22 screwed into the female screw portion 1d is rotated and moved back and forth, the coil spring 21 is expanded and contracted, and the drag force is increased or decreased.

  The screw member 28 includes first and second divided members 28a and 28b each having a half-cut hooked cylindrical shape obtained by dividing the hooked cylindrical member into two on the diameter. On the outer peripheral surfaces of the first and second split members 28a and 28b, large-diameter flange portions 31a and 31b that contact the operation knob 27 at the front end portions are formed on the inner peripheral surface of the operation knob 27 at the intermediate portion. Male screw portions 29a and 29b that can be screwed into the portion 27a are formed. The flange portions 31a and 31b are formed so as to protrude outward in the radial direction, and the outer diameters of the flange portions 31a and 31b are larger than the outer shape of the male screw portions 29a and 29b. Accordingly, when the female screw portion 27 a formed on the inner periphery of the operation knob 27 is screwed into the male screw portions 29 a and 29 b formed on the outer periphery of the screw member 28, the operation knob 27 is moved to the flange portion 31 a of the screw member 28. , 31b to be securely attached to the screw member 28. At the rear end portions of the inner peripheral surfaces of the first and second divided members 28a, 28b, retaining half-projections 30a, 30b for engaging with the retaining groove 26 are formed projecting radially inward. ing. A pair of positioning protrusions 32a (FIG. 3) is formed on the split surface of the first split member 28a facing the second split member 28b. A pair of positioning holes (not shown) are formed on the split surface of the second split member 28b facing the first split member 28a. Thus, the two divided members 28a and 28b are reliably positioned, and the divided male screw portions 29a and 29b are aligned so as to be able to be screwed into the female screw portion 27a.

  Next, the operation of the rear drag reel will be described.

  When the yarn is fed from the reel unit 1, the bail arm 4 is tilted to the yarn release side. When the fishing rod is cast, the fishing line is fed out from the spool 3. At the time of winding the yarn, the bail arm 4 is returned to the yarn winding side. When the handle 10 is rotated in the yarn winding direction in this state, this rotational force is transmitted to the pinion gear 12 via the handle shaft 10a and the master gear 11. The rotational force transmitted to the pinion gear 12 rotates the rotor 2 at the front portion of the pinion gear 12. On the other hand, the rotational force transmitted to the pinion gear 12 rotates the screw shaft 15 via an intermediate gear (not shown) that meshes with the pinion gear 12. At this time, the slider 16 engaged with the spiral groove of the screw shaft 15 is guided by the guide shaft and moves in the front-rear direction. When the slider 16 moves, the spool shaft 14 and the spool 3 reciprocate in the front-rear direction together with the slider 16. By such rotation of the rotor 2 and movement of the spool 3 back and forth, the fishing line guided from the bail arm 4 and the line roller 5 is uniformly wound around the outer periphery of the spool 3 in the front-rear direction.

  The rear drag mechanism 9 brakes the spool 3 and can adjust the drag force on the spool 3 by rotating the operation knob 27. When the operation knob 27 at the rear part of the reel body 1 is tightened, the pressing member 22 moves forward, and the coil spring 21 that contacts the pressing member 22 is pressed. Then, the plurality of friction plates 19a, 19b, 19c of the friction engagement portion 19 are pressed against each other, and the bush 18 is pressed toward the reel body 1a by the plurality of friction plates 19a, 19b, 19c. Thus, when the bush 18 is pressed toward the reel body 1a, the spool shaft 14 that cannot rotate with respect to the bush 18 is also difficult to rotate, and the drag force acting on the spool 3 is increased. On the other hand, when the operation knob is loosened, the pressing member 22 moves rearward, and the state where the coil spring 21 is pushed is gradually released. Then, the pressing of the bush 18 by the friction plates 19a, 19b, and 19c is released, and the spool shaft 14 that cannot rotate with respect to the bush 18 is easily rotated, and the drag force acting on the spool 3 is weakened.

  Next, the assembly procedure of the braking operation structure will be described.

  When assembling the braking operation structure 6, the rear drag mechanism 9 is first assembled and the spring member 24 is mounted in the annular mounting groove 25. Then, both the split members 28a and 28b are attached to the mounting cylinder portion 1c in a state where the half annular protrusions 30a and 30b are engaged with the retaining groove 26.

The mounting cylinder portion 76 includes a male screw portion 77 formed on the reel body 51 a and a cylindrical portion 83 formed integrally with the male screw portion 77. The first and second screw members 78 and 79 are provided with female screw portions 84a and 84b that can be screwed into the male screw portion 77 of the mounting cylinder portion 76, respectively. The cylindrical portion 83 is formed to have a larger diameter than the inner diameters of the female screw portions 84a and 84b of the first and second screw members 78 and 79.

  The first and second screw members 78 and 79 are divided into a semi-cylindrical shape in the axial direction, and the first and second butted portions 85a and 86a (85b and 86b) are formed on the screw members 78 and 79, respectively. Yes. The first screw member 78 is mounted on the mounting cylinder portion 76 so that it can be screwed on the rear side of the male screw portion 77 and the second screw member 79 is positioned on the front side of the male screw portion 77. In the first butted portions 85a and 85b of the first and second screw members 78 and 79, projecting portions 88a and 88b projecting in the radial direction are respectively formed on the outer peripheral surfaces. In order to transmit the operation of the second screw member 79 to the pressing member 72 between the second screw member 79 and the pressing member 72, a locking portion that locks the pressing member 72 so as not to be rotatable and to be movable in the axial direction. 87 is arranged.

  As shown in FIGS. 5 and 6, the first operating member 81 is formed in a bottomed cylindrical shape and has a storage portion 83 a that can store the cylindrical portion 83. A pressing portion 90 is integrally formed at the bottom of the storage portion 83a. The first operation member 81 is attached to a first screw member 78 that is screwed onto the outer periphery of the external thread portion 77 of the attachment cylinder portion 76.

  The first and second operation members 81 and 82 have a concave portion 92a formed on the inner surface of the cylinder, and the concave portion 92a can be fitted into the protruding portions 88a and 88b of the first and second screw members 78 and 79. ing. Here, after fitting the recess 92a and the protrusions 88a, 88b, a restricting portion 93a is formed at the front part of the bottom of the recess 92a so that the protrusions 88a, 88b do not come out of the recess 92a. The restricting portion 93a is formed by a protrusion that protrudes from the bottom of the recess 92a toward the centers of the first and second screw members 78 and 79.

  Next, the operation of the rear drag reel will be described.

  When the yarn is fed from the reel unit 51, the bail arm 54 is tilted to the yarn release side. When the fishing rod is cast, the fishing line is fed out from the spool 53. At the time of winding the yarn, the bail arm 54 is returned to the yarn winding side. When the handle 60 is rotated in the yarn winding direction in this state, this rotational force is transmitted to the pinion gear 62 via the handle shaft 60a and the master gear 61. The rotational force transmitted to the pinion gear 62 rotates the rotor 52 at the front portion of the pinion gear 62. On the other hand, the rotational force transmitted to the pinion gear 62 rotates the screw shaft 65 via an intermediate gear (not shown) that meshes with the pinion gear 62. At this time, the slider 66 that meshes with the spiral groove of the screw shaft 65 is guided by the guide shaft 67 and moves in the front-rear direction. When the slider 66 moves, the spool shaft 14 and the spool 53 reciprocate in the front-rear direction together with the slider 66. Due to the rotation of the rotor 52 and the back-and-forth movement of the spool 3, the fishing line guided from the bail arm 54 and the line roller 55 is evenly wound around the outer periphery of the spool 53 in the front-rear direction.

  The rear drag mechanism 59 is for adjusting the drag force on the spool 53 by rotating the first and second operation members 81 and 82. When the first operating member 81 at the rear of the reel body 51 is tightened, the pressing portion 90 formed integrally with the first operating member 81 moves forward, and the coil spring 71 connected to the pressing portion 90 is pressed. Then, the surfaces of the plurality of friction plates 69a of the first friction engagement portion 69 are close to each other, and the first flange portion 73 of the bush 68 is sandwiched between the plurality of friction plates 69a. Thus, when the first flange portion 73 of the bush 68 is pressed, the spool shaft 64 that cannot rotate with respect to the bush 68 is also difficult to rotate, and the drag force acting on the spool 53 is increased. On the other hand, if the 1st operation member 81 is loosened, the press part 90 will move back and the state where the coil spring 71 was pushed in will be cancelled | released gradually. Then, the pressing of the first flange portion 73 by the friction plate 69 a is released, and the spool shaft 64 that cannot rotate with respect to the bush 68 is easily rotated, and the drag force acting on the spool 53 is weakened.

  When the second operation member 82 is tightened, the second screw member 79 rotates together with the second operation member 82. Then, the pressing member 72 moves forward along the spool shaft 64 via the engaging portion 87 disposed between the second screw member 79 and the pressing member 72. By the movement of the pressing member 72, the surfaces of the plurality of friction plates 70a of the second friction engagement portion 70 are close to each other, and the second flange portion 74 of the bush 68 is sandwiched between the friction plates 70a. By pressing the second flange portion 74 of the bush 68 in this way, the spool shaft 64 that cannot rotate with respect to the bush 68 is also difficult to rotate, and the drag force acting on the spool 53 is increased. On the other hand, when the second operation member 82 is loosened, the pressing member 72 moves rearward along the spool shaft 64 and is pulled back in the direction away from the second friction engagement portion 70. Then, the pressing of the second flange portion 74 by the friction plate 70a is released, and the spool shaft 64 that cannot rotate with respect to the bush 68 is easily rotated, and the drag force acting on the spool 53 is weakened.

  Next, the assembly procedure of the braking operation structure 56 will be described.

  When assembling the braking operation structure 56, first, the divided second screw member 79 is screwed and attached to the front of the male screw portion 77 of the mounting cylinder portion 76. Subsequently, a retaining ring member formed in a C shape is mounted on the outer peripheral surface of the second screw member 79, and the second screw member 79 is fixed to the mounting cylinder portion 76. Then, the second operation member 82 formed in a cylindrical shape is fitted into the second screw member 79 from the cylindrical portion 83 side, and the concave portion 92a formed in the cylindrical inner surface of the second operation member 82 is inserted into the second screw member 79. It fits in the protrusion part 88b provided in the 1st butting | matching part 85a of 79. FIG. Next, the divided first screw member 78 is screwed and attached to the rear side of the male screw portion 77 of the mounting cylinder portion 76. Subsequently, the bottom portion of the first operating member 81 formed in the bottomed cylindrical shape is opposed to the cylindrical portion 83, and the pressing portion 90 formed in the bottom portion of the first operating member 81 is inserted into the mounting cylinder portion 76. Meanwhile, the cylindrical portion of the first operating member 81 is fitted into the first screw member 78. Then, the recess 92 a formed on the cylindrical inner surface of the first operation member 81 is fitted into the protrusion 88 a provided on the first screw member 78.

  In the braking operation structure 56 of the present embodiment assembled in this way, even if the cylindrical portion 83 is formed larger in diameter than the thread inner diameter of the female thread portions 84a and 84b of the first and second screw members 78 and 79, Since both screw members 78 and 79 are divided, they can be easily mounted on the mounting cylinder portion 76. Further, if the outer shapes of the screw members 78 and 79 are made larger than the outer shape of the cylindrical portion 83, the first and second operation members 81 and 82 can be easily attached to the screw members 78 and 79.

  On the other hand, even if the first and second operation members 81 and 82 and the first and second screw members 78 and 79 can be easily attached to the attachment cylinder portion 76, both the operation members 81 and 82 and the both screw members Considering that 78 and 79 do not fall out of the mounting cylinder portion 76 is important in terms of preventing problems such as the rear drag mechanism 59 being disassembled. In the braking operation structure 56 of the present embodiment, the screw members 78 and 79 are formed by the cylindrical portion 83 of the screw-in portion 86 formed larger than the screw thread inner diameter of the female screw portions 84a and 84b of the screw members 78 and 79. The drop-out from the mounting cylinder portion 76 is restricted. Further, since the concave portions 92a of both the operation members 81 and 82 are fitted into the projecting portions 88a and 88b of the both screw members 78 and 79, the both operation members 81 and 82 cannot rotate with respect to both the screw members 78 and 79 and the shaft The direction cannot be moved. For this reason, as long as the screw members 78 and 79 are prevented from falling off, the operation members 81 and 82 attached to the screw members 78 and 79 will not fall out of the mounting cylinder portion 76.

  From the above, in the braking operation structure 56 of the present embodiment, the operation knob (first and second operation members 81 and 82) can be easily mounted on the mounting cylinder portion 76 while the function of the rear drag mechanism 59 remains unchanged. In addition, the first and second operating members 81 and 82 can be stably rotated with respect to the mounting cylinder portion 76. In addition, the first and second operation members 81 and 82 can be prevented from being detached from the mounting cylinder portion 76 without using a fixing bolt, so that the first and second operation members 81 and 82 do not impair the appearance. Can be mounted on the mounting cylinder 76. In addition, both operation knobs can be prevented from falling off the mounting cylinder portion 76 without using a retaining member.
