Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fishing reel, and in particular, prevents a rotating body such as a spool or a rotor from unintentionally rotating due to a pulling force of a fishing line in a feeding direction. For improvement of the reverse rotation prevention mechanism for.

[Conventional technology]

Conventionally, as a reverse rotation stop mechanism for fishing reels
Japanese Laid-Open Patent Application No. 5-32463 and Japanese Utility Model Publication No. 59-32282 are known.

In this type of reverse rotation stop mechanism, a ratchet wheel is fixed to a rotary shaft that is rotated by a rotating operation of a handle, a pawl member engaging and disengaging the ratchet wheel is rotatably attached to a reel frame, and the pawl member is spring-loaded. By keeping the engaged state with the rotation shaft, the rotation shaft cannot be rotated with respect to the rotation in the yarn feeding direction, and the rotation shaft can be rotated with respect to the rotation operation of the handle in the yarn winding direction. .

[Problems to be solved by the invention]

In the conventional reverse rotation prevention mechanism for fishing reels as described above,
The number of teeth of the ratchet wheel is generally composed of 6 to 8 teeth. Therefore, for example, even in the case of 8 teeth, the angle between the teeth is as large as 45 °, and therefore The angle until the claw member is locked and stopped in reverse rotation, that is, the idling angle becomes large, and there are problems as described below.

For example, when releasing the fishing line from the spinning reel,
When the bail is free and the fishing line is vigorously swung down, the handle arm rotates by the amount of play corresponding to the idling angle due to inertia,
At this time, when the bail arm collides with the bail return of the reel body, the bail is returned to the bobbin winding posture, and at the same time, the releasing thread is suddenly stopped by the bail that has been stopped in the reverse direction, so that the fishing line has an excessive tension. There is a risk that the thread will be cut and the thread will be cut.

In addition, when the fishing rod is vigorously lifted due to rooting,
A large impact force at the time of stopping reverse rotation acts on the ratchet wheel and the claw member, and the claw member and the like are damaged, which is likely to cause a failure. Further, since the idling angle is large when the reverse rotation is stopped, there is a problem that dandruff easily occurs.

[Purpose of device]

The present invention has been made in order to solve the above-mentioned problems, and reduces the idling angle at the time of stopping reverse rotation to enable reliable stop of reverse rotation, and at the same time, to reduce the impact force at the time of stopping reverse rotation. It is an object to provide a fishing reel that eliminates dandruff and thread cutting.

[Means for solving problems]

The present invention relates to a fishing reel in which rotation by a handle operation supported by a reel body is transmitted to a bobbin-wound rotating body via a rotation transmission system incorporated in the reel body. A one-way bearing is fitted to the outer circumference of the one-way bearing, and a ratchet wheel is fixed to the outer circumference of the one-way bearing while being retained, and a locking claw is switched and held between the engaged and disengaged states on the ratchet wheel. is there.

[Function of device]

In the present invention, since the reverse rotation stop mechanism is configured by the one-way bearing and the method of connecting the bearing to the reel body via the ratchet wheel and the locking claw, reliable reverse rotation stop is possible, and the idling angle when the reverse rotation is stopped. Also, the impact force can be reduced.

[Example of device]

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway side view showing an example in which a reverse rotation stop mechanism according to the present invention is applied to a spinning reel.

In the figure, reference numeral 1 is a reel body provided with legs 2 for attaching to a fishing rod. A hollow flyer shaft 4 passing through the front wall 3 of the reel body 1 at a right angle is rotatably mounted by a bearing 5. Has been done.

A pinion 6 is formed on the outer periphery of the protruding portion of the flyer shaft 4 in the reel body.
It is meshed with the drive gear 7 arranged inside. The drive gear 7 is perpendicular to the flyer shaft 4 and the reel body 1
A handle 10 for thread winding operation is fixed to a handle shaft 9 which is fixed to a drive shaft 8 which is rotatably provided horizontally and which is fitted and fixed in the drive shaft 8.

Further, as shown in FIGS. 1 and 2, a one-way bearing 11 is fitted to the outer periphery of the reel body protruding portion of the flyer shaft 4, and the ratchet wheel 1 is attached to the outer periphery of the one-way bearing 11.
2 is concentrically fitted to prevent rotation. 13 is the above-mentioned claw wheel 1
Screw pin 14 on front wall 3 of reel body 1 close to 2
Is a dogleg-shaped locking claw that is rotatably attached by means of a spring 15. The locking claw 13 is urged by a spring 15 in a direction in which one end of the locking claw 13 is engaged with the ratchet wheel 12, and the other end thereof is
A cam 16 that engages and disengages the locking claw 13 with respect to the ratchet wheel 12 is engaged, and the cam 16 is fixed to a rod 17 penetratingly supported in the reel body 1 in the front-rear direction, and the rod 17 protrudes outside the reel body. A switching lever 18 is fixed to the end.

In FIG. 1, reference numeral 19 is a flyer arranged on the front surface of the reel body 1 and is provided with a bail 20. The flyer 19 is fitted concentrically with the tip of the flyer shaft 4 and screwed onto the flyer shaft 4. It is fixedly fastened integrally by a matching nut 21. Reference numeral 22 denotes a spool shaft penetratingly supported in the hollow hole of the flyer shaft 4 so as to be slidable in the axial direction thereof and non-rotatable relative to the flyer shaft 4. A spool 23 is attached to a front protrusion of the spool shaft 22 so as to be relatively rotatable. The spool 23 and the spool shaft 22 are frictionally coupled by a drag device 24. The protruding end of the spool shaft 22 inside the reel body is connected to an oscillating mechanism (not shown) that reciprocates the spool 23 in the front-rear direction in synchronization with the rotation of the flyer 19.

Next, the operation of the spinning reel of the present embodiment configured as described above will be described.

In FIG. 2, when the switching lever 18 is operated to the position shown by the solid line, the locking claw 13 is rotated clockwise by the spring 15 and one end of the locking claw 13 is locked to the claw wheel 12, so that the claw 13 is locked. It prevents the car 12 from rotating counterclockwise in the figure.

In this state, when the fishing line (not shown) wound around the spool 23 is to be discharged, the bail 20 is set free and the fishing line is swung down vigorously. As a result, the fishing line is sequentially paid out from the spool 23. At this time, the locking claw 13 is engaged with the ratchet wheel 12, and the rotation between the ratchet wheel 12 and the flyer shaft 4 in the reverse direction of the arrow B is locked by the one-way bearing 11. Since the roller is locked by being wedge-shaped engaged between the outer circumference of the flyer shaft 4 and the outer ring of the one-way bearing 11, the idling angle at the time of reverse rotation becomes small. Therefore, when the fishing line is discharged, the handle 10 hardly rotates due to the inertia of the fishing rod even if the fishing rod is swung down vigorously, and the arm 20a of the bail 20 which is freely set as in the conventional case hits the bail return 1a of the reel body 1. The bail 20 is not shaken off.

When the handle 10 is rotated in the yarn winding direction indicated by the arrow A in FIG. 1, the rotation is transmitted from the handle shaft 9 to the flyer shaft 4 through the drive shaft 8-drive gear 7-pinion 6 and the flyer 19 and The fishing line is wound around the spool 23 by rotating the bail 20. At this time, the one-way bearing 11 is in a free state with respect to the rotation of the flyer shaft 4 in the direction opposite to the arrow B, and is urged by the spring 15 in the direction in which the locking claw 13 is engaged with the ratchet wheel 12 to be in the engaged state. The holding wheel 12 is hardly rotated because it holds.

On the other hand, during the fishing line winding operation, when the tackle connected to the fishing line is rooted or a fish is caught in the tacking device and the fishing rod is greatly lifted and a sudden tension is applied to the fishing line, the ratchet wheel 12 and the one-way bearing are used. Since both of 11 bear the load at the time of stopping the reverse rotation, the locking claw 13 and the screw pin 14 thereof are not applied with an impact load, and there is no possibility of causing a trouble in strength. Since the idling angle is small, no yarn dandruff occurs and reliable reverse rotation stop is possible.

When the switching lever 18 is operated to the position indicated by the chain double-dashed line in FIG. 2, the locking claw 13 is disengaged from the ratchet wheel 12, and the flyer shaft 4 is moved.
Is in a state in which it can freely rotate in the yarn winding and yarn feeding directions. This state is set when the fishing tackle is fed out or when the fish caught in the fishing tackle is fighting.

FIG. 3 is a sectional view of an essential part showing a second embodiment in which the reverse rotation stop mechanism of the present invention is provided on the handle shaft side of a spinning reel.

In the figure, the same parts as those in FIG. 1 are designated by the same reference numerals, the description thereof will be omitted, and the parts different from those of FIG. 1 will be mainly described.

That is, in this embodiment, as is apparent from FIG. 3, the one-way bearing 25 is fitted to the outer periphery of the one end portion of the drive shaft 8 horizontally rotatably mounted on the reel body 1 by the bearing 24. A locking claw 27 is fitted to the outer periphery of the direction bearing 25 so as to prevent the claw wheel 26 from rotating, and further, a locking claw 27 similar to that shown in FIG. It is a thing.

In the second embodiment configured as described above, the same effect as that of the first embodiment can be obtained.

4 and 5 show a third embodiment in which the reverse rotation stop mechanism of the present invention is applied to a dual bearing reel.

In the figure, 30 is a reel body, and a handle shaft 32 is rotatably supported by bearings 33, 33 between an inner plate 31a and an outer plate 31b of one side frame 31 constituting the reel body. Drive gear 3 on shaft 32
4, the drive gear 34 and the handle shaft 32 are frictionally coupled to each other by a drag device 35. A unidirectional bearing 36 is fitted on the outer circumference of the handle shaft 32.
A ratchet wheel 37 is fitted around the outer periphery of the so as not to rotate. Further, in the vicinity of the ratchet wheel 37, a locking claw 38 that engages with and disengages from the ratchet wheel 37 is pivotally attached to the inner plate 31a by a pin 39, and the locking claw 38 is fixed by a leaf spring 40.
It is urged in the direction of engaging with 7, and is switched in the engagement / disengagement direction by a switching lever 41 provided outside the side frame 31.

In the dual-bearing reel configured as described above, when the handle shaft 32 is rotationally operated in the direction of arrow B in FIG. 5, the handle shaft 32 is unidirectionally fixed and held via the ratchet wheel 37 and the locking claw 38. Since the bearing 36 is in the free state, the handle shaft 32 is rotated clockwise in FIG. 4, and this rotation is transmitted to the spool (not shown) via the drive gear 34.

Further, when a sudden tension is applied to the fishing line fed from the spool and an attempt is made to rotate the spool in the line feeding direction, the one-way bearing 36 locks to prevent the spool from rotating in the line feeding direction. Then, when a tension larger than the drag force of the drag device 35 acts on the fishing line, the drag device 35 slips, and the drive gear 34 rotates with respect to the handle shaft 32 in the locked state.
At the same time, the spool also rotates to prevent thread breakage.

Also in the third embodiment of the present invention, the first
The same effect as that of the embodiment can be obtained.

The reverse rotation stopping method of the present invention is not limited to the spinning reel and the dual-bearing reel as shown in each of the above-mentioned embodiments, but can be applied to a covered reel, a single-bearing reel, and the like.

[Effect of device]

As described above, according to the present invention, the one-way bearing is fitted to the outer circumference of the rotating body rotated by the handle operation, and the ratchet wheel is fixed to the outer circumference of the one-way bearing while being engaged with the ratchet wheel. Since the pawl is switched and held between the engaged state and the disengaged state, the idling angle at the time of the reverse rotation stop operation can be reduced and the hooking operation can be reliably performed, and the bail may accidentally fall off when the line dander or the fishing line is discharged. Therefore, it is possible to prevent the occurrence of trouble in practical use. Further, by releasing the locking claw from the ratchet wheel, the handle can be reversely rotated and the fishing line can be easily fed to a predetermined point, so that a wide range of fishing operations can be supported. Further, since the ratchet wheel is fitted around the outer periphery of the one-way bearing, the unitized commercially available one-way bearing can be easily configured to prevent the reel from rotating in reverse.
