Description

  The present invention relates to a fishing reel provided with a drag mechanism that applies a braking force to the rotation of a spool that is rotatably supported between side plates of the reel body, and a reverse rotation prevention mechanism that prevents the spool from reversing in the direction of feeding the fishing line. About.

  The drag lever provided on one side plate of the reel body is swung in the front-rear direction to move the spool in the axial direction to drive the spool, and a drag disk that is prevented from reversing is attached to the friction plate provided on the spool flange. Patent Document 1 discloses a fishing reel (lever drag reel) provided with a drag mechanism that press-contacts and applies a braking force to rotation of a spool in a fishing line feeding direction.

  Thus, this type of fishing reel is widely used mainly for medium to large reels because a large force is applied when the spool is rotated.

The fishing reel disclosed in Patent Document 1 uses a reverse rotation prevention mechanism that uses a ratchet to prevent the reverse rotation of the drag disk that is brought into pressure contact with the friction plate of the spool flange, and for winding that transmits the rotational force of the handle to the spool. The transmission system includes a gear transmission mechanism and the drag mechanism.
No. 7-39413

  However, as described above, in the structure in which the reverse rotation prevention of the drag disk is performed by the reverse rotation prevention mechanism using the ratchet, rattling occurs in the rotation direction of the ratchet, which causes rattling when the spool reverse rotation is stopped. It has been pointed out that there is a problem that undesirably becomes a shock when the fish are combined and lacks certainty.

  In addition, the fishing reel includes a high-speed gear (first gear) and a low-speed gear (second gear) that are idle-supported on the handle shaft and engaged with either one of the two gears so that power from the handle shaft can be obtained. An engagement piece for transmitting the gear is slidably attached to the handle shaft along the axis of the handle shaft, and the third gear and the fourth gear meshing with the high speed gear and the low speed gear are loosely supported on the spool shaft, The gear speed change mechanism is configured by mounting an operation shaft for setting the position of the engagement piece in the handle shaft. However, the meshing backlash between the high and low speed gears and the third and fourth gears, The looseness in the reverse direction of the handle greatly occurs due to the looseness of engagement with the low-speed gear, which is not preferable for actual fishing operation and store quality (the customer confirms the performance by operating various reels). It was a fact.

  The present invention has been devised in view of such circumstances, and an object of the present invention is to provide a fishing reel in which the handle is prevented from rattling in the reverse direction and the quality is improved.

  In order to achieve such an object, the invention according to claim 1 is characterized in that a high-speed winding high-speed gear and a low-speed winding low-speed gear are idle-supported on the outer periphery of a cylindrical handle shaft on which the handle is mounted. An engagement member that engages with either the high-speed gear or the low-speed gear and transmits power from the handle shaft is provided slidably along the axis of the handle shaft while being rotated around the handle shaft. In a fishing reel in which an operating member for setting the position of the engaging member is mounted in the handle shaft so that it can be pressed from the outside, the rolling member of the rolling one-way clutch contacts the outer periphery of the handle shaft. The rolling-type one-way clutch allows rotation in one direction of the handle shaft and prevents rotation in the other direction, and the handle shaft is disposed on the axial side portion of the rolling-type one-way clutch. Lee through Characterized by being rotatably supported by the body.

  According to the first aspect of the invention, since the reverse rotation prevention of the spool during actual fishing is performed by the reverse rotation prevention mechanism using the rolling type one-way clutch on the handle shaft, unnecessary shocks are eliminated at the time of fish matching. In addition, the rolling type one-way clutch instantly regulates the rotation of the handle in the reverse direction during actual fishing and store display, so there is no backlash in the reverse direction of the handle and the store quality is dramatically improved. It was improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 7 show a fishing reel according to one embodiment of the present invention. Like the fishing reel disclosed in Patent Document 1, this embodiment relates to a lever drag reel, which is shown in FIG. As described above, the spool 5 is supported on the spool shaft 3 supported by the reel body 1 so as to be rotatable and movable in the axial direction, through the bearings 7 and 9, and from the cylindrical handle shaft 13 to which the handle 11 is attached. A fishing reel 19 is provided with a winding power transmission system that transmits power to the spool 5 via the gear transmission mechanism 15 and the drag mechanism 17.

  As shown in FIG. 1 and FIG. 2, the gear transmission mechanism 15 includes a high-speed winding high-speed output gear (high-speed gear) 21 and a low-speed winding low-speed output gear (low-speed gear). ) 23, and the high-speed input gear 25 and the low-speed input gear 27 that are meshed with these and are idled on the outer periphery of the handle shaft 3, and the power from the handle shaft 13 is transmitted to the high-speed output gear 21 and the low-speed output gear 23. In order to transmit to either one, the engagement member (frame) 29 that can be engaged with the engagement holes 21a and 23a provided in the high-speed output gear 21 and the low-speed output gear 23, and the position of the engagement member 29 are set. The high-speed output gear 21 and the low-speed output gear 23 are constituted by a holding plate 37 and a washer by a tightening force of a nut 35 screwed to a screw portion 33 at the distal end on the insertion side of the handle shaft 13. With 39 Is lifting, it is idle supported via a collar 41 on the outer periphery of the handle shaft 13.

  As shown in FIG. 2, the engagement holes 21 a and 23 a are provided in the high-speed output gear 21 and the low-speed output gear 23 with an interval of 90 °, and the engagement member 29 is provided on the handle shaft 13. The pair of slits 43 provided at the distal end of the insertion side are slidably stopped and supported.

  Further, as shown in FIG. 1, the handle 11 is attached to the protruding end of the side plate 45 of the handle shaft 13 in a state in which the handle 11 is prevented from rotating. Built to be movable.

  As shown in FIGS. 2 and 4, the operation member 31 is a shaft member in which the engaging member 29 is screwed to the tip (may be integrated by press fitting, bonding, retaining ring, etc. other than screwing). 47, an operating shaft 49 that can be pressed from the outside, a coil spring 51 provided between the operating shaft 49 and the shaft member 47, a large-diameter head 53 of the shaft member 47, and an insertion tip of the handle shaft 13 The engaging member 29 is urged to both sides in the axial direction by the coil springs 51 and 57. The coil spring 57 is provided between the stepped portion 55 projecting from the inner periphery of the side. A circumferential groove 59 is provided at the outer end of the operation shaft 49.

  Thus, the coil spring 51 is set to have a spring force stronger than that of the coil spring 57. When the operating shaft 49 is pushed into the handle shaft 13 as shown in FIG. The shaft member 47 is pressed while the coil spring 57 is contracted, and the engagement member 29 is engaged with the engagement hole 23a of the low-speed output gear 3, and the restoring force of the coil springs 51 and 57 as shown in FIG. When the shaft member 47 moves in the direction of the arrow and the operation shaft 49 is pulled out, the engagement member 29 is engaged with the engagement hole 21 a of the high-speed output gear 21.

  Therefore, when the engaging member 29 is engaged with the engaging hole 23a of the low speed output gear 3 as shown in FIG. 4, the gear transmission mechanism 15 is in a low speed state, and the engaging member 29 is engaged with the high speed output gear 21 as shown in FIG. When engaged with the hole 21a, the gear transmission mechanism 15 is switched to a high speed state.

  3 to 7, the handle 11 is provided with a stopper 61 that engages with the circumferential groove 59 of the operation shaft 49, and the gear speed change mechanism 15 is in a low speed state as shown in FIG. At this time, the stopper 61 is engaged with the circumferential groove 59 so as to position and hold the operation shaft 49.

  As shown in FIGS. 3 and 4, the stopper 61 is disposed flush with the operation lever 65 mounted in the handle cover 64 attached to the base 63 of the handle 11 so as to be rotatable in the direction of the arrow. The two engagement pieces 67 are integrated so as to be connected to the operation lever 65 by sandwiching an engagement protrusion 69 provided on the inner periphery of the operation lever 65.

  A coil spring 75 is provided between a protrusion 71 having an L-shaped cross section formed on the upper portion of the stopper 61 and a support member 73 mounted in the handle cover 64. It is always biased downward (in the direction of locking with the circumferential groove 59 of the operation shaft 49). Therefore, as shown in FIGS. 3 and 4, when the locking portion 77 provided on the stopper 61 is locked in the circumferential groove 59 of the operation shaft 49, such a state is maintained by the spring force of the coil spring 75. As described above, the operation shaft 49 is positioned and held.

  When the operation lever 65 is rotated from the position indicated by the solid line in FIG. 3 to the position indicated by the solid line in FIG. 5, the stopper 61 connected and engaged with the operation lever 65 is converted into a direction orthogonal to the operation shaft 49, and the coil spring. 75, and the locking portion 77 of the stopper 61 and the circumferential groove 59 are unlocked, and the restoring force of the coil springs 51, 57 releases the shaft member 47 and the operating shaft. 49 is instantaneously moved in the direction of arrow A in FIG. 6 so that the gear transmission mechanism 15 is switched to a high speed state. Then, as shown in FIG. 6, the locking portion 77 of the stopper 61 is pressed against the outer periphery of the operation shaft 49 by the restoring force of the coil spring 75, and the operating lever 65 is positioned near the position of FIG. It is configured to be held back.

  In order to switch the gear transmission mechanism 15 from the high speed state to the low speed state, the operation shaft 49 may be pressed inward as shown in FIG. 4 in the state of FIG.

  As shown in FIGS. 1 and 4, the handle shaft 13 is rotatably supported via bearings 79 and 81 disposed on the inner side and the outer side of the side plate 45 so as to be rotatable. A rolling one-way clutch (hereinafter referred to as “one-way clutch”) 83 is attached to the side plate 45 between 79 and 81.

  The rolling member 85 of the one-way clutch 83 comes into contact with the outer periphery of the handle shaft 13, and this cylindrical handle shaft 13 functions as an inner ring of the one-way clutch 83. Reversal prevention that allows rotation of the shaft 13 (handle 11) in the forward rotation direction (fishing line winding direction) and restricts rotation of the handle shaft 13 (handle 11) in the reverse rotation direction (fishing line feeding direction) by its wedge action. It functions as a mechanism and also functions as an anti-reverse mechanism for the spool 5 that is pressure-coupled to the drag mechanism 17.

  On the other hand, as shown in FIG. 1, the drag mechanism 17 includes a friction plate 89 attached to the spool flange 87 of the spool 5 and a drag disk 91 pressed against the friction plate 89, and is provided at the center of the drag disk 91. A thick connecting portion 93 is integrally connected to the low speed input gear 27, and the high speed input gear 25 is integrally connected to the low speed input gear 27.

  Further, a ratchet 95 for preventing the spool 5 from reversing in the direction of feeding the fishing line is fixed to the outer periphery of the connecting portion 93, and a locking claw 97 attached to the reel body 45 is locked to the ratchet 95. .

  Thus, in this embodiment, the reverse rotation prevention mechanism by the one-way clutch 83 on the handle shaft 13 and the reverse rotation prevention mechanism by the ratchet 95 on the spool shaft 3 prevent the reverse rotation of the spool 5 in the fishing line feeding direction. ing.

  Thus, the frictional force of the drag device 17 is adjusted as follows.

  A rotation knob 101 for adjusting the position of the cam body 99 arranged coaxially with the spool shaft 3 is screwed to the end of the spool shaft 3 on the handle 11 side. A drag lever 103 that swings around the coaxial axis and the axis of the spool shaft 3 is disposed between the two. As described above, the spool 5 is loosely supported on the spool shaft 3 via the bearings 7 and 9, and the position thereof is regulated by the disc spring 105 so that the movement toward the counter handle is prevented. .

  Further, the cam surfaces of the cam body 99 and the drag lever 103 are configured to climb up, and when the drag lever 103 is swung, the spool shaft 3 is slid in the axial direction on the reel body 1 on the handle 11 side. It is designed to move.

  Therefore, when adjusting the frictional force between the friction plate 89 of the drag mechanism 17 and the drag disk 91, the position of the cam body 99 is set to an appropriate position by the rotary knob 101, and the drag lever 103 is operated. When the spool shaft 3 is pulled toward the handle 11, the spool 5 moves in the direction of the drag disk 91, so that the friction force between the friction plate 89 and the drag disk 91 increases, and conversely, the spool shaft 3 is counteracted. When pushed into the handle side, the frictional force of the drag mechanism 17 decreases. If the friction plate 89 and the drag disk 91 are separated from each other, the friction force of the drag mechanism 17 is eliminated, and the spool 5 is allowed to roll.

  In addition, in FIG. 1, 107 is a known click mechanism comprising a click gear 109 mounted on the side opposite to the handle of the spool 5 and a click body 111 which can be freely engaged and disengaged therewith.

  Since the present embodiment is configured as described above, in order to feed the fishing line, the drag lever 103 is operated to separate the friction plate 89 and the drag disk 91, and the spool 5 becomes free. The fishing line is fed out by rotating in the fishing line feeding direction.

  On the other hand, in order to wind up the fishing line when the fish is caught, the drag lever 103 is operated and the spool shaft 3 is slid to the handle 11 side so that the friction plate 89 is pressed against the drag disc 91. When adjusting the frictional force with the drag disk 91, the rotary knob 101 may be operated.

  Then, if the operating shaft 49 is pushed into the handle shaft 13 and the engaging member 29 is engaged with the engaging hole 23a of the low speed output gear 23 as shown in FIG. When the operating force of the handle 11 is transmitted to the spool 5 and the operating lever 65 is operated as shown by the solid line in FIG. 5 in this low speed state, the stopper 61 (the locking portion 77) and the circumferential groove of the operating shaft 49 59, the operation shaft 49 and the shaft member 47 are moved in the direction of arrow A, and the engagement member 29 is engaged with the engagement hole 21a of the high-speed output gear 21, as shown in FIG. The gear transmission mechanism 15 is switched to a high speed state.

  Further, during the winding operation, a load is applied to the spool 5 in the direction of feeding the fishing line by pulling the fish. Since the ratchet 95 has a degree of freedom in the rotation direction, the spool 5 tries to rotate in the fishing line feeding direction, but the high-speed output gear meshed with the high-speed input gear 25 and the low-speed input gear 27 integral with the drag disk 91. 21 or the low speed output gear 23 is engaged with the engaging member 29, and the engaging member 29 is controlled by the one-way clutch 83 in the fishing line feeding direction. Therefore, the rotation of the spool 5 in the fishing line feeding direction is restricted by the one-way clutch 83.

  When a strong reverse load is applied to the spool 5 and the one-way clutch 83 slips and does not act as a wedge, the anti-reverse mechanism by the ratchet 95 and the locking claw 97 functions, and the fishing line feeding direction of the spool 5 Rotation to is surely regulated.

  Furthermore, the one-way clutch 83 instantaneously regulates the rotation of the handle 11 in the reverse direction during actual fishing or store display.

  As described above, this embodiment is configured so that the reverse rotation prevention of the spool 5 (drag disk 91) during actual fishing is performed by the reverse rotation prevention mechanism using the one-way clutch 83 on the handle shaft 13, so that it is not necessary when fish are combined. And the one-way clutch 83 instantaneously regulates the rotation of the handle 11 in the reverse direction at the time of actual fishing or display at the store, so that the handle 11 is not rattled in the reverse direction. Quality has improved dramatically.
