Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag mechanism, and more particularly to a drag mechanism for a fishing reel for braking the rotation of a spool for a spool mounted on a reel body of a fishing reel in a line feeding direction.

[0002]

2. Description of the Related Art Fishing reels such as spinning reels, dual-bearing reels and single-bearing reels are provided with a drag mechanism for braking the rotation of a spool in a line payout direction. The drag mechanism can adjust the drag force by operating the drag operation member. Generally, a drag mechanism of a fishing reel includes a first member provided on a spool or an interlocking member interlocking with the spool.
A disk and a second disk provided opposite to the first disk and capable of being pressed against the first disk by operating a drag operation member. In a dual-bearing reel, the second disk is changed to a first disk (for example, a main gear) by operating a star drag screwed to a handle shaft or a drag lever (an example of a drag operation member) provided swingably on the reel body. On the other hand, the spool is braked by being pressed against the first disk by being relatively moved in the axial direction of the handle shaft and the spool shaft. In the spinning reel, a drag knob provided at the end of the spool and screwed to the spool shaft is rotated, and the second
By moving the disk in the axial direction of the spool shaft,
The spool is braked by being pressed against a disk (for example, a spool).

In the drag mechanism of this type of fishing reel,
During drag operation, both disks rotate relative to each other with a constant frictional force due to the pulling of the fish. Thereby, a stable drag force is obtained.

[0004]

In the conventional drag mechanism utilizing the frictional force, the frictional force between the two disks is set to be large at the beginning of the drag operation and then reduced from the difference between the static friction coefficient and the dynamic friction coefficient. A so-called start-up hiccup is likely to occur due to the drag force provided. When start-up hiccups occur, the tension applied to the fishing line changes rapidly, so that the fishing line is liable to dander and the fish is likely to come off the hook. In addition, a phenomenon in which the drag force fluctuates due to a difference in pulling, that is, a difference in the payout speed of the fishing line at the time of drag operation, easily occurs. When such a phenomenon occurs, even if the drag force is set correctly, the drag force fluctuates, and the drag setting must be repeated.

[0005] It is an object of the present invention to provide a drag mechanism for a fishing reel that minimizes fluctuations in drag force due to differences in starting and scratching and pulling.

[0006]

A drag mechanism for a fishing reel according to a first aspect of the present invention is a mechanism for braking the rotation of a spool for a bobbin mounted on a reel body of a fishing reel in a line payout direction. It has one disk, a second disk, and an adjustment mechanism. The first disk rotates in conjunction with the spool and has an annular first braking surface.
The second disk is non-rotatably connected to the reel body at least in the line reel-out direction, has a second braking surface facing the first braking surface of the first disk, and presses the first disk. The adjusting mechanism is a mechanism that can adjust the pressing force of the second disk. At least one of the first braking surface of the first disk and the second braking surface of the second disk has one or a plurality of annular grooves.

In this drag mechanism, when the drag is actuated and the spool rotates in the line feeding direction, the first disk rotates in conjunction with the spool and rotates relative to the second disk. At this time, the second disk presses the first disk at this time, and the spool is braked. This pressing force can be adjusted by the adjusting mechanism, and the drag force can be adjusted arbitrarily. Here, since an annular groove is formed along one of the braking surfaces in the rotation direction, the coefficient of static friction and the coefficient of kinetic friction are close to each other, and the first disk starts rotating smoothly with respect to the second disk at the beginning of the drag operation. , Start hibernation can be suppressed. Further, as shown in FIGS. 5 and 6, the degree of dependence on the line payout speed is reduced, so that fluctuations in drag force due to differences in pulling can be suppressed.

According to a second aspect of the present invention, there is provided a drag mechanism for a fishing reel according to the first aspect, wherein the plurality of annular grooves are arranged concentrically. In this case, since the annular groove is arranged concentrically, it is not necessary to change the shape during processing,
It is easy to form an annular groove.

A drag mechanism for a fishing reel according to a third aspect of the invention is the mechanism according to the first or second aspect, wherein the fishing reel is a spinning reel, and the first disk is formed integrally with the spool on the inner peripheral side of the spool. The second disk is mounted non-rotatably on a spool shaft that is non-rotatable with respect to the reel body and has a spool rotatable and axially immovable. In this case, since the spool and the first disk are integrated, the configuration of the drag mechanism is simplified.

A drag mechanism for a fishing reel according to a fourth aspect of the present invention is the mechanism according to the first or second aspect, wherein the fishing reel is a dual-bearing reel, and the first disk is a main gear that rotates in conjunction with the spool. The second disk has a main gear rotatably mounted thereon and is non-rotatably mounted on a handle shaft which is prohibited from rotating in the line payout direction.
In this case, in the star drag type drag mechanism of the dual-bearing reel, it is possible to suppress the drag fluctuation due to the starting hiccup and the feeding speed.

A drag mechanism for a fishing reel according to a fifth aspect of the present invention is the drag mechanism according to any one of the first to fourth aspects, wherein the drag disk is disposed between the first disk and the second disk so as to be in contact with both disks. Is further provided. In this case, since the drag disk is interposed therebetween as compared with a configuration in which both disks directly rub against each other, the fluctuation of the drag force can be further suppressed.

A drag mechanism for a fishing reel according to a sixth aspect of the present invention is the mechanism according to the fifth aspect, wherein the drag disk is made of felt or carbon graphite. When the drag disk is made of felt, the coefficient of friction is reduced, and the fluctuation of the drag force due to the starting hiccup and the speed can be further suppressed. Also, when the drag disk is made of carbon graphite, deformation due to heat is reduced,
In particular, stable drag performance can be obtained even when the number of disks increases.

Is in contact with a cover member 68 described later to prevent the liquid from entering the inner peripheral side. The lip of the seal plate 71 is in contact with a cylindrical contact member 76 tightly fitted on the inner peripheral surface of the drag storage portion 4h. The contact member 76 is a high-precision part whose inner peripheral surface is machined, and the sealing performance can be improved by bringing the lip into contact with the inner peripheral surface of such a contact member 76.

The projection 71c of the seal plate 71 is in contact with the bottom. The cylindrical portion 68a of the cover member 68 is provided with two spring pins 74 on the outer peripheral surface of the knob main body 67, for example.
It is fixed by. Such a hollow spring pin 74 can be removed by inserting and hooking a wire-like jig from the center hole. Spring pin 7

The seal band 75 is an annular body made of an elastic body having a rectangular cross section, and is mounted in a slightly extended state.

The friction portion 62 includes a disk member (an example of a second disk) 81 that contacts the first member 63, a drag sound generating mechanism 83 mounted on the disk member 81, and a spool 4.
Has a disk-shaped wall portion (an example of a first disk) 4k, and a drag disk 82 disposed between the disk member 81 and the wall portion 4k. The disk member 81 has the inner disk portion 8

A drag sound generating mechanism 83 is attached to 1c, and is in contact with the front surface of the wall 4k via a drag disk 82 made of graphite. The drag sound generating mechanism 83 sounds when the spool shaft 15 and the spool 4 are relatively rotated, that is, when the drag is operated.

In the drag mechanism 60 configured as described above, since the two annular grooves 85 are formed in the wall 4k along the rotation direction, the coefficient of static friction and the coefficient of dynamic friction are close to each other, and the starting hiccup is reduced. Drag performance that is set to be suppressed can be stably exhibited. That is, if the coefficient of static friction and the coefficient of dynamic friction are significantly different, the drag force at the start of the drag operation becomes about 30 to 60% larger than the drag force thereafter, but by forming the annular groove 85, the value becomes 10 to 2%.
It can be suppressed to about 0%.

Further, the fishing line is less affected by the feeding speed of the fishing line due to the difference in pulling, and the drag force is stabilized regardless of the pulling strength. The effect of the difference in the feeding speed between the drag mechanism 60 having two annular grooves 85 according to the present invention and the conventional drag mechanism without the annular grooves was tested. The results of this experiment are shown in FIGS. Here, FIG. 5 shows a case of the product of the present invention equipped with the drag mechanism according to the present invention, and FIG. 6 shows a conventional product without an annular groove. The solid line is 1 m /
s shows the case where the fishing line was paid out at a low speed of s.
This shows a case where the program is fed at a high speed of m / s.

As is clear from FIGS. 5 and 6, in the product of the present invention, the fluctuation of the drag force between high speed and low speed is small.
The fluctuation range is about 17% on average. On the other hand, in the case of the conventional product having no annular groove, the average is 40%, and it can be seen that it fluctuates considerably between high speed and low speed. As a result, it was found that the set drag force greatly fluctuated with respect to the actual drag force due to the difference in fish pull.

As described above, by forming the annular groove 85, it is possible to suppress the starting scratching immediately after the start of the drag operation and to bring the drag force closer to the set drag force.
The drag force after the drag operation can be stabilized regardless of the difference in pull.

[Operation and Operation of Reel] In this spinning reel, the bail arm 40 is tilted to the line releasing position at the time of yarn feeding such as at the time of casting. As a result, the fishing line is sequentially fed out from the leading end side of the spool 4 by its own weight.

When winding the yarn, the bail arm 40 is returned to the yarn winding posture. When the handle assembly 1 is rotated in the yarn winding direction, this is automatically performed by the action of a bail reversing mechanism (not shown). The rotational force of the handle assembly 1 is
The power is transmitted to the pinion gear 12 via the master gear shaft 10 and the master gear 11. The torque transmitted to the pinion gear 12 is transmitted from the front portion 12 a to the rotor 3 and transmitted to the oscillating mechanism 6 by the intermediate gear 23 via a coupling mechanism meshing with the pinion gear 12. As a result, the rotor 3 rotates in the line winding direction and the spool 4 reciprocates back and forth.

When the fish is pulled on the fishing tackle with a stronger force than the drag force set, the drag mechanism 60 operates. At this time, the starting hiccup is suppressed, and the drag force thereafter becomes stable regardless of the difference in pulling.

[Other Embodiments] (a) In the above embodiment, a front drag type spinning reel has been described as an example. However, the present invention is also applicable to a rear drag type spinning reel and a drag mechanism of another type of fishing reel. Can be applied.

FIG. 7 shows a star drag type drag mechanism of a dual bearing reel, FIG. 8 shows a lever drag type drag mechanism of a dual bearing reel, and FIG. 9 shows a drag mechanism of a single bearing reel. Is shown.

In FIG. 7, the star drag type dual-bearing reel is a reel in which a spool 90 and a handle shaft 91 to which a handle 99 is non-rotatably mounted at the end are connected via a clutch mechanism 92. The drag force of the drag mechanism 93 that brakes the rotation of the spool 90 in the line feeding direction is adjusted by rotating the star drag 94. The drag mechanism 93 is arranged in the middle of a rotation transmission mechanism 95 that transmits the rotation of the handle 99. The drag mechanism 93 includes a star drag 94 screwed to the handle shaft 91, a main gear (an example of a first disk) 96 that rotates in conjunction with the spool 90, and a disk member (non-rotatably mounted on the handle shaft 91). An example of the second disk 97, and a drag disk 98 disposed between the main gear 96 and the disk member 97. The rotation of the handle shaft 91 in the line feeding direction is prohibited. Two annular grooves 96a are formed on the contact surface of the main gear 96 with the drag disk 98. The disk member 97 is a star drag 9
4 and presses the main gear 96 via the drag disk 98.

In the drag mechanism 93 of the star drag type dual-bearing reel having the above-described structure, the start-up hiccup is improved by the annular groove 96a, and the fluctuation of the drag force due to the difference in pulling can be suppressed.

In FIG. 8, the lever drag type dual bearing reel is a reel in which a spool 105 and a spool shaft 106 are connected via a clutch mechanism 107. In the drag mechanism 100 that brakes the spool 105, the drag force is adjusted by the spool shaft 106 moving in the axial direction by the swing operation of the drag lever 101. Drag mechanism 100 is arranged in the middle of rotation transmitting mechanism 103 that transmits the rotation of handle 102. The drag mechanism 100 includes the spool 9
There is provided a first drag portion 110 non-rotatably mounted on the spool shaft 106 which rotates in conjunction with the rotation shaft 0, and a second drag portion 111 connected to the rotation transmission mechanism 103. The rotation of the rotation transmission mechanism 103 in the line payout direction is prohibited.
The two drag portions 110 and 111 are disposed so as to be able to press against each other. When the drag lever 101 is operated, the first drag portion 110 moves in the axial direction together with the spool shaft 106,
The pressing force with the second drag portion 111 changes, and the drag force is adjusted. A disk (an example of a first disk) 110a made of graphite is fixed to the first drag portion 110, and a stainless steel alloy is attached to the second drag portion 111 so as to face the disk (an example of the second disk) 110a. Disk 111a is fixed. On the opposing surface of the disk 111a, two annular grooves 111b are formed concentrically.

In the drag mechanism 100 having such a structure,
Spool 1 by pulling fish exceeding the set drag power
When the first drag portion 110 rotates with respect to the second drag portion 111 by rotating the 05 in the line feeding direction, the same effect as in the above-described embodiment can be obtained. The same effect can be obtained also in a lever drag type dual bearing reel in which a disk is directly fixed to a spool.

In FIG. 9, the single-bearing reel is a reel in which the spool 121 is directly rotated by the handle 120. The drag mechanism 122 that brakes the spool 121 includes:
The drag force is adjusted by the swing operation of the drag knob 123. The drag mechanism 122 is disposed inside the spool 121. The drag mechanism 122 includes a cylindrical holder 125 connected to a spool shaft 130 via a one-way clutch 124, a disk member 128 mounted on the holder 125, and a drag disk 126 arranged in contact with the disk member 128. And a pressing mechanism 127 for pressing the drag disk 126. On the braking surface of the disk member 128 facing the drag disk 126,
An annular groove 128a is formed. One end surface of the holder 125 is in contact with the inner end surface of the spool 121 via two washers 129a and 129b. The one-way clutch 124 allows the holder 125 to rotate in the line winding direction with respect to the spool shaft 130, but prohibits relative rotation in the line payout direction. Drag disk 12
Reference numeral 6 denotes a graphite ring-shaped member,
It is arranged between the other end surface of the second member 25 and the pressing mechanism 127 so as to be able to contact both.

In this embodiment as well, the same effects as in the above embodiment can be obtained when the fishing line is pulled out by hand or when the fishing line is drawn out by pulling a fish. (B) In the above embodiment, the annular grooves are arranged concentrically, but they may be arranged eccentrically. Further, the location where the annular groove is formed is not limited to the first disk which rotates in conjunction with the spool, and may be formed on the second disk or on both disks.

[0052]

According to the present invention, since an annular groove is formed in one of the braking surfaces along the rotation direction, the coefficient of static friction and the coefficient of kinetic friction are close to each other, and the first disk is moved relative to the second disk at the beginning of the drag operation. The disc starts to rotate smoothly, and startup hiccups can be suppressed. Further, since the degree of dependence on the line feeding speed is reduced, fluctuations in drag force due to differences in pulling can be suppressed.
