Description

  The present invention relates to a fishing spinning reel provided with a rotor reverse rotation prevention mechanism.

As is well known in the art, a fishing spinning reel (hereinafter referred to as “spinning reel”) has a semi-annular veil at the tip of a pair of support arms provided on a rotor via a bale support member and a fishing line winding position. It is attached to the discharge position so that it can be reversed.
Then, when the bale is tilted to the fishing line discharge position and the device is cast, the fishing line wound around the spool is fed out spirally, and when the bale is reversed to the fishing line winding position and the handle is wound up, the rotor is The fishing line is wound on a spool that rotates (forward rotation) in the fishing line winding direction and reciprocates in the front-rear direction of the reel body in conjunction with the rotation of the rotor.

By the way, the conventional spinning reel has a reverse rotation prevention mechanism that prevents the rotation of the drive mechanism that rotationally drives the rotor during casting or fishing line winding operation and prevents the rotation of the rotor in the fishing line feeding direction (reverse rotation). As a mechanism for preventing reverse rotation, a rolling type one-way clutch (hereinafter referred to as “one-way clutch”) is used to switch between rotation of the rotor in both forward and reverse directions and prevention of reverse rotation of the rotor. Is widely known. The one-way clutch is accommodated in a bottomed cylindrical storage portion provided at the front portion of the reel body, and the storage portion projects from the cylindrical portion of the rotor.

In Patent Document 1, a seal member is attached to the front portion of the storage portion to make the one-way clutch waterproof, and water that has entered the storage portion through a slight gap of the seal member due to capillary action or the like has accumulated. A spinning reel is disclosed in which a through-hole for draining water is provided at the bottom of the storage portion, and the through-hole is closed with a lid member when the spinning reel is used.
JP 2003-259770 A

However, as described above, the through hole has a structure that is closed by the lid member when the spinning reel is used. Therefore, when draining water, the lid member must be removed using a tool or the like. In some cases, the through hole is closed by the lid member, so that the water accumulated in the storage unit cannot be drained during actual fishing.
Furthermore, in order to positively drain water from the through hole, there is an annoyance that requires an operation unrelated to the actual fishing operation, such as swinging or shaking the spinning reel.

The present invention has been devised in view of such circumstances, and an object thereof is to provide a spinning reel capable of draining water with a simple operation .

In order to achieve such an object, the present invention provides a rotor rotatably supported by a reel body on which a fishing rod mounting leg is formed, a drive mechanism for driving the rotor by operating a handle attached to the reel body, and a casting time. And a reverse rotation prevention mechanism comprising a one-way clutch for preventing reverse rotation of the rotor by preventing reverse rotation of the drive mechanism during the winding operation of the fishing line, and a reel body having a storage portion for storing the one-way clutch. rotor at a spinning reel which projects into the cylindrical portion of the inner peripheral surface of the cylindrical portion of the rotor, with a tapered surface expanding to the rear of the reel body, housed on the opposite side to the fishing rod attachment leg A through hole for draining is provided on the peripheral wall of the portion so as to face the inner peripheral surface of the cylindrical portion .

According to the present invention, since the through hole for draining the storage portion is provided on the opposite side of the fishing rod mounting leg, that is, below the spinning reel, even if water enters the storage portion, In addition, there is an advantage that it is not necessary to perform an operation unrelated to the actual fishing operation, such as when water is efficiently dripped from the through-hole efficiently when the handle is operated and the spinning reel is shaken or shaken in order to positively drain the water.
And the water dripped from the through-hole adheres to the internal peripheral surface of the cylindrical part of a rotor. However, since the rotor rotates at high speed by operating the handle during actual fishing, the water adhering to the inner peripheral surface of the cylindrical portion receives a force in the outer peripheral direction by centrifugal force, but the inner peripheral surface is a tapered surface that expands backward. Therefore, the direction of the force of the water droplet is changed by such a tapered surface, and as a result, water can be actively drained to the outside through the gap between the rotor and the reel body which is the rear.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 3 show a first embodiment of a spinning reel according to the present invention . In FIG. 1, reference numeral 1 denotes a hollow supported rotatably on the front portion of a reel body 5 via bearings 2 and 3. A rotor shaft (flyer shaft) has a rotor 7 fixed to the tip thereof with a nut 9. In addition, a drive gear 17 that is non-rotatably fitted to the handle shaft 15 of the handle 13 is meshed with the pinion 11 provided on the outer periphery of the rear end side of the rotary shaft 1, and the handle 13 is rotated (winding operation). Is transmitted from the drive gear 17 and the pinion 11 to the rotary shaft 1 so that the rotor 7 rotates in the direction of winding the fishing line.

As described above, the drive mechanism for driving the rotor 7 includes the handle shaft 15 and the drive gear 17, the pinion 11, and the rotary shaft cylinder 1 that are attached to the handle shaft 15.
A pair of support arms 19 are integrally extended to the front of the reel body 5 at the base of the rotor 7, and a bail support member 21 is attached to the tip of the support arms 19, respectively, at the fishing line winding position and the fishing line. It is reversibly attached to the discharge position. A semi-annular bail 23 is attached between the bale support members 21, and the line roller 25 is rotatably attached to one bail support member 21.

In the figure, reference numeral 27 denotes a spool shaft that is slidably supported by being inserted into the rotary shaft 1. A spool 29 is attached to the rotor-side protruding end of the spool shaft 27, and a traverse to the rear end side of the spool shaft 27. A mechanism (spool reciprocating device) 31 is mounted.
As is conventionally known, the traverse mechanism 31 includes a screw shaft (traverse cam shaft) 33 that is rotatably supported in the reel body 5 in parallel with the spool shaft 27, and a cam groove 35 provided on the outer periphery of the screw shaft 33. And a follower gear 39 that is fitted to the front end of the screw shaft 33 and meshes with the pinion 11, and the slider 37 is a spool. The rear end portion of the shaft 27 is fixed with screws 41.

  Then, when the bale 23 is tilted to the fishing line discharge position and the device is cast, the fishing line wound around the spool 29 is fed out spirally, and the bail 23 is tilted toward the fishing line winding position and the handle 13 is wound up. Then, the screw shaft 33 rotates through the pinion 11 and the driven gear 39, and the slider 37 that engages with the cam groove 35 through the engaging claw reciprocates on the screw shaft 33. The spool 29 is reciprocated in the front-rear direction of the reel body 5 via the spool shaft 27 connected to the moving element 37, and the fishing line is wound around the spool 29.

Further, a fishing rod mounting leg 43 is provided on the reel body 5 upward.
In addition to the above-described configuration, the spinning reel 44 according to the present embodiment also prevents the drive mechanism that rotationally drives the rotor 7 from rotating in the casting direction of the rotor 7 during casting or fishing line winding operation. An anti-reverse mechanism 47 using a one-way clutch 45 that prevents the rotation (reverse rotation) is mounted.

2 and 3 show details of the reverse rotation prevention mechanism 47, in which 49 is a bottomed cylindrical storage portion protruding from the front of the reel body 5 around the spool shaft 27. Protrudes into the cylindrical portion 7a at the center of the rotor 7, and a one-way clutch 45 is accommodated therein. In the present embodiment, the storage portion 49 is formed integrally with the reel body 5, but may be formed separately from the reel body.
The one-way clutch 45 includes an outer ring 51 fixed to the inner periphery of the storage portion 49, an inner ring 53 that is fixed to the outer periphery of the rotating shaft cylinder 1 having a non-circular cross section, and a plurality of rollers 55 in the circumferential direction. A retainer 57 that is held at equal intervals, and a stopper ON / OFF switching plate (hereinafter referred to as a “switching plate”) 61 that engages with a convex engagement portion 59 provided outside the retainer 57. The retainer 57 is rotatably disposed between the inner and outer rings 53 and 51. As shown in FIG. 2, the one-way clutch 45 is prevented from coming off by two thin disk-like pressing plates 63 and 65 fixed to the storage portion 49, and the inner ring 53 is connected via the bearing 2. It is supported by the storage portion 49.

  Thus, as shown in FIG. 3, the outer circumference of the inner ring 53 is a circular circumferential surface, whereas the inner circumference of the outer ring 51 has a shallow groove as a wedge area from a deep groove as a non-wedge area in the circumferential direction. A recess 67 formed in each of the rollers 55 is provided to correspond to each roller 55, and the roller 55 bites between the wedge region and the inner ring 53 to prevent the inner ring 53 and the rotating shaft cylinder 1 from being reversed. When the roller 55 is moved, the inner ring 53 and the rotary shaft cylinder 1 can rotate in both forward and reverse directions with respect to the outer ring 51.

  The switching plate 61 is provided with a projecting piece 71 in which a cam hole 69 is formed. A stopper ON / OFF switching lever (hereinafter referred to as “switching”) inserted into the cam hole 69 on the rear side of the reel body 5. The operating rod 75 of 73) is engaged. As described above, the storage portion 49 for storing the one-way clutch 45 is formed in a cylindrical shape. However, as shown in FIG. 3, the protrusion 71 and the operating rod 75 are provided on the peripheral wall of the storage portion 49. A convex storage portion 49 a to be stored and disposed projects from the fishing rod mounting leg 43.

  Further, a spring (not shown) is stretched between the projecting piece 71 and the inner wall of the storage portion 49, and the spring force causes the switching plate 61 and the retainer 57 to pass through as shown by a two-dot chain line in FIG. The roller 55 is urged toward the wedge region of the outer ring 51 (concave portion 67). When the switching plate 61 is rotated to the position shown by the solid line in FIG. 3 by operating the switching lever 73 against the spring force of the spring, the retainer 57 rotates in conjunction with this, so that the retainer 57 The roller 55 accommodated in the inner ring moves from the wedge region of the outer ring 51 (recessed portion 67) to the non-wedge region, and the one-way clutch 45 can rotate in the reverse direction (stopper OFF state; the rotor 7 can rotate in both forward and reverse directions). 3), and when this state is released by operating the switching lever 73, the switching plate 61 rotates to the position indicated by the two-dot chain line in FIG. The biased roller 55 bites between the wedge region of the outer ring 51 and the inner ring 53, and the one-way clutch 45 is switched to a reverse rotation prevention state (stopper ON state; reverse rotation prevention state of the rotor 7). It has become way.

As shown in FIGS. 2 and 3, the inner peripheral surface 7 b of the cylindrical portion 7 a of the rotor 7 is a tapered surface that expands to the rear of the reel body 5. Further, one through hole 77 for draining is provided on the peripheral wall of the storage portion 49 located on the opposite side of the fishing rod mounting leg 43 so as to face the inner peripheral surface 7b of the cylindrical portion 7a. Is opened below the spinning reel 44 .
The through hole 77 may be a circular hole or a long hole as long as it functions as a drain, and the shape and size are not particularly limited. It is also possible to provide a plurality of through-holes 77 with an emphasis on weight reduction and drainage function of the entire reel.

  Since the present embodiment is configured as described above, when the bail 23 is tilted to the fishing line discharge position and the device is cast, the fishing line wound around the spool 29 is fed out in a spiral shape, and the bail 23 is wound on the fishing line. When the handle 13 is wound up by being tilted to the position side, the rotor 7 rotates (forward rotation) in the fishing line winding direction, and the spool 29 is moved in the front-rear direction of the reel body by the traverse mechanism 31 in conjunction with the rotation of the rotor 7. The fishing line is wound around the spool 29 by reciprocating movement, but if the switching lever 73 is operated to bring the switching plate 61 to the position shown by the two-dot chain line in FIG. 53 and the one-way clutch 45 (reverse rotation prevention mechanism 47) enters the reverse rotation prevention state (stopper ON state), so that the rotation of the rotor 7 in the fishing line feeding direction (reverse) Rolling) is prevented.

On the other hand, when the switching plate 61 is rotated to the position shown by the solid line in FIG. 3 by operating the switching lever 73, the roller 55 moves from the wedge area of the outer ring 51 to the non-wedge area, and the one-way clutch 45 (reverse rotation prevention mechanism 47). ) Is switched to the reverse rotation possible state (stopper OFF state), so that the rotor 7 can be rotated in both forward and reverse directions.
During actual fishing, water enters the storage portion 49 through a slight gap between the holding plate 63 and the bearings 2 and 3 due to a capillary phenomenon or the like. A through hole 77 for draining water is formed on the peripheral wall of the storage portion 49. Since the opening is provided on the side opposite to the mounting leg 43, that is, below the spinning reel 44, the water that has entered the storage portion 49 naturally drops outside through the through-hole 77.

Since then Thus, Such dropwise water to the outside from the through hole 77 adheres to the inner circumferential surface 7b of the cylindrical portion 7a of the rotor 7 but the rotor 7 in actual fishing to high rotation by operating the handle 13, a cylindrical Although the water droplets adhering to the inner peripheral surface 7b of the portion 7a receive a force in the outer peripheral direction due to the centrifugal force , the inner peripheral surface 7b is a tapered surface that expands rearward. Is positively discharged to the outside through a gap 79 between the rotor 7 and the reel body 5 which is the rear .
Thus, in the present embodiment, the inner peripheral surface 7b of the cylindrical portion 7a of the rotor 7 is a tapered surface that expands to the rear of the reel body 5, and the peripheral wall of the storage portion 49 that is located on the opposite side of the fishing rod mounting leg 43. Further, since the through hole 77 for draining is provided opposite to the inner peripheral surface 7b of the cylindrical portion 7a, even if water enters the storage portion 49, unlike the conventional example of Patent Document 1, actual fishing It is not necessary to perform an operation unrelated to the actual fishing operation, such as when water is efficiently dripped from the through-hole 77 efficiently at the time of operation or when the handle is operated, and the spinning reel 44 is shaken or shaken to actively drain water.

And the water dripped to the outside from the through hole 77 adheres to the inner peripheral surface 7b of the cylindrical portion 7a of the rotor 7, but by rotating the rotor 7 by rotating the handle 13, the centrifugal force acting on the rotor 7 and Water droplets adhering to the inner peripheral surface 7b can be positively discharged from the gap 79 between the rotor 7 and the reel body 5 by a synergistic action with the inner peripheral surface 7b of the cylindrical portion 7a having a taper surface expanding rearward. Is possible.
