Abstract

The invention provides a force-unloading mechanism of a fishing reel for use in fishing. In the force-unloading mechanism, operation of an operating unit can be carried out with a small operating force even if a braking force is large. The force-unloading mechanism (23) is used for inhibiting rotation of a winding reel (12) for winding wires in a paying off direction of a double-bearing fishing reel (100) and has a driving shaft (300) having a first outer thread part (30f), a star-shaped force-unloading mechanism (3), a friction mechanism (4), and a fluororesin-containing non-electrolytic nickel plating (90). The star-shaped force-unloading mechanism (3) has an inner thread part (3d) threaded on the first outer thread part (30f). The friction mechanism (4) changes a frictional force by enabling the star-shaped force-unloading mechanism (3) to swing and inhibits rotation of the winding reel (12) in the paying off direction. The fluororesin-containing non-electrolytic nickel plating (90) is formed on the first outer thread part (30f).

As shown in Figure 3, the star-like force mechanisms 3 that unloads has: main part 3b, and it has multiple operating portion 3a that are radial setting; Nut part 3c, its in main part 3b can with this main part 3b unitary rotation, and can move axially; Nut part 3c has the internal thread part 3d for being screwed on the 1st external thread part 30f.The star-like force mechanisms 3 that unloads is for to press the functional unit so that the brake force of defined is adjusted to the friction mechanism 4 being arranged on driving shaft 30 at its base end side.Star-like unloading between force mechanisms 3 and the 1st one-way clutch 86,4 disc springs 88 are installed.Disc spring 88 is for passing to keep plate 62 described later by the star-like power that screws tight buffering of unloading force mechanisms 3.Disc spring 88 is arranged on star-like unloading between the nut part 3c of force mechanisms 3 and the inner ring 86b of the 1st one-way clutch 86.

The star-like force mechanisms 3 that unloads screws tight degree by adjusting it, the inner ring 86b that can make the 1st one-way clutch 86 between disc spring 88(with reference to Fig. 3,4) move vertically, wherein the 1st one-way clutch 86 is arranged on driving shaft 30 on the 2nd side cover 7.,, by rotating the star-like force mechanisms 3 that unloads, adjust the pressing force of disc spring 88.Thus, can carry out meticulous adjustment to brake force by the star-like force mechanisms 3 that unloads.

Friction mechanism 4 has: keep plate 62, and it is bonded on driving shaft 30 and can unitary rotation; An example of ratchet 61(friction plate).Keep plate 62 is plectane parts, and between the 1st unload power pad 63a by handle 2 sides an example with driven wheel 31(the 2nd friction plate) contact.Keep plate 62 be arranged on the 3rd fastener 30e upper and can with driving shaft 30 unitary rotation.Keep plate 62 clamps driven wheel 31 with ratchet 61.In addition, keep plate 62 connects and contacts the inner ring 86b of the 1st one-way clutch 86, and can not rotate to it.Therefore, the inner ring 86b of the 1st one-way clutch 86 can with driving shaft 30 unitary rotation, and the star-like pressing force that unloads force mechanisms 3 is passed to and unloads power plate 62.On the central part that unloads power plate 62, be formed with conjugate foramen 62a, this conjugate foramen 62a can engage with inner ring 86b and can unitary rotation, and can engage with the 3rd fastener 30e of driving shaft 30 and can unitary rotation.Driving shaft 31 unloads power pad 63b between the 2nd and contacts with ratchet 61.

The 2nd unloads the frictional disk that power pad 63b is ring-type, and is arranged between ratchet 61 and driven wheel 31.Be provided with annular element 64 in the 2nd inner circumferential side of unloading power pad 63b.Annular element 64 can rotate with respect to driving shaft 30.In addition, annular element 64 has the engagement pin 64a that is positioned at driven wheel 31 sides.Any one in a pair of conjugate foramen 31a, 31b that engagement pin 64a forms and connects with on the side of driven wheel 31 engages.Therefore, annular element 64 rotates with the rotation of driven wheel 31.The thickness of annular element 64 is less than the 2nd thickness that unloads power pad 63b.Therefore, press and unload power plate 62 by the star-like force mechanisms 3 that unloads, even if driven wheel 31 clamps by keep plate 62 and ratchet 61, also can not make pressing force act on annular element 64, thereby this annular element 64 can rotate.

Sound generating mechanism 65 has: impulse pin 70, and it is arranged on geared parts 49 and can forward-reverse in driving shaft direction; Sounding recess 71, it is multiple, and is formed on the side with the contrary side of handle side of annular element 64, and interval arranges in a circumferential direction; Helical spring 72, it loads impulse pin 70 to annular element 64.Impulse pin 70 has the head that top engages with sounding recess 71.Impulse pin 70 and helical spring 72 are received to be contained in cylindrical portion 49a, and this cylindrical portion 49a is towards outstanding setting the in side of the handle side of geared parts 49.Cylindrical portion 49a, its size is set as inserting near the through hole 61b forming the centre bore of ratchet 61, and exposes towards annular element 64 sides.Multiple sounding recesses 71 are formed on the side of the impulse pin 70 of annular element 64, and interval arranges in a circumferential direction.In the sound generating mechanism 65 of said structure, by the effect of brake force, when driving shaft 30 and driven wheel 31 are relatively rotated, the impulse pin 70 that can not rotate with respect to driving shaft 30 collides and sounding repeatedly with the sounding recess 71 forming on annular element 64, and wherein annular element 64 rotates together with driven wheel 31.

Next, the action of this double-bearing fish-line wheel is described.

In the time of coiling fishing line, handle 2 is rotated to winding direction.The rotation of handle 2 is transmitted to the driven wheel 31 rotating with the rotation of driving shaft 30 and pinion 32 between unloading force mechanisms 23 by driving shaft 30.The rotation of pinion 32 by clutch mechanism 21 to transmitting with the chimeric spool axle 20 of pinion 32, thereby spool 12 is rotated and fishing line is rolled.The rotation of this driving shaft 30 is transmitted to transverse cam axle 46 between geared parts 49 and geared parts 48, by the rotation of transverse cam axle 46, fishing line guide part 47 is moved back and forth along spool axle 20.By this reciprocating motion, fishing line is roughly wrapped on spool 12 equably.

On the other hand, in the time of unwrapping wire, operated clutch handle 17 also makes the separated state of clutch mechanism 21 by clutch control mechanism 22.Thus, remove chimeric between spool axle 20 and pinion 32, even rotate because unwrapping wire makes spool 12, also this rotation can not passed to rotation transfer mechanism 19 and driving shaft 30.

Next, the action of unloading force mechanisms 23 is described.

When angling on fish, on fishing line, can form tension force.Thus, on spool 12, effect has the moment of torsion making to unwinding direction rotation.But, in the time acting on brake force on spool 12 and be less than the brake force setting, by by the star-like power that screws tight of unloading force mechanisms 3 and the effect of compressed disc spring 88, make driven wheel 31 unload power pad 63a between the 1st and be clamped in ratchet 61 and unload in power plate 62, and driven wheel 31 and driving shaft 30 can not be relatively rotated.In addition, because driving shaft 30 is by preventing its rotation to unwinding direction of reversing gearbox 66 engagements, so the spool 12 rotating with the rotation of driven wheel 31 can not rotate to unwinding direction.Have again, here owing to unloading and be inserted with the 1st between power pad 63b and the power of unloading plate 62 and driven wheel 31 and unload power pad 63a being inserted with the 2nd between ratchet 61 and driven wheel 31, thus by the pressing force of little disc spring 88 can make ratchet 61, the transferable moment of torsion that unloads between power plate 62 and driven wheel 31 increases.

When being attached to tension force on fishing line and increasing the moment of torsion that makes to be attached on spool 12 and increase, via ratchet 61, unload the 2nd between power plate 62 and driven wheel 31 and unload part that power pad 63b and the 1st unloads the face contact of power pad 63a and produce and slide.Thus, though engagement (prevention) rotation of driving shaft 30, driven wheel 31 overcomes the resistance of kinetic force of friction and rotates to unwinding direction, and spool 12 also rotates to unwinding direction.Thus, in the time acting on moment of torsion on spool 12 and exceed the value of defined, that is to say, do the used time when fishing line is subject to excessive tension force, unload force mechanisms 23 and move and spool 12 is rotated towards unwinding direction, thus fishing line when protection was subject to hightension effect.

When spool 12 rotates to unwinding direction as described above when upwards having angled fish, unload the sound generating mechanism 65 of force mechanisms 23 and sound.That is, now driving shaft 30 and driven wheel 31 relatively rotate, and the sounding recess 71 forming on the annular element 64 that makes to rotate with the rotation of driven wheel 31 is interfered and sent click (rattling away) sound with the impulse pin 70 rotating with the rotation of geared parts 49.Geared parts 49 can not rotate with respect to driving shaft 30.This click sound is that the sounding recess 71 with uniformly-spaced arranging that makes the head of impulse pin 70 be intermittence by the loading of helical spring 72 contacts and produces rhythmical sound.In the time that this sound produces, because being thinner than the 2nd, the thickness of annular element 64 unloads power pad 63b, and in addition, by the gap between engagement pin 64a and stop hole 31a, make annular element 64 radially or axially all maintain to a certain degree loosening state.
