Description

[Detailed description of the invention] A. Purpose of the invention [Field of industrial application] The present invention relates to a drag mechanism for a double-bearing reel for fishing.

[Conventional example]

The drag mechanism of conventional double-bearing reels (especially baitcasting reels) has a star-shaped drag handle attached to the bottom of the handle, and is configured to adjust the drag force by screwing in or loosening this. The drag handle is provided to rotate together with the handle.

In addition, in the conventional double bearing reel mentioned above, a level wind mechanism is provided so that the fishing line can be evenly wound around the spool, and a master gear is provided at one end of the traverse cam shaft and interlocked with the spool shaft by a gear transmission mechanism. In addition to the connection, a drag force is built into the master gear side, and a handle is attached to both the left and right ends of the traverse cam shaft so that the left and right handles can be attached interchangeably, and the spool and level wind mechanism are connected by rotation of the traverse cam shaft. The present applicant had previously proposed a device configured to drive and rotate.

However, when the above-mentioned drag mechanism is attached to the above-mentioned left and right handle double-bearing reel, if the handle is attached to the gear side of the traverse cam shaft, that is, the side to which the master gear is attached, it can be used in the same way as a conventional reel. If it is installed on the side opposite to the gear side, the drag handle will remain on the gear side of the traverse cam shaft and rotate as the handle rotates, so the drag handle may get in the way when palming or pinch your fingers. There are problems that may cause problems such as danger.

[Problem that the invention attempts to solve]

Therefore, as a result of studies in view of the above-mentioned conventional problems, the present invention was developed by omitting the conventional drag handle in a double-bearing reel in which handles can be attached interchangeably to both the left and right ends of the traverse cam shaft. The rotating body for drag adjustment should not protrude outward from the reel body, and instead of the above drag handle, a drag switch is provided on the side frame, and by switching the drag switch, the handle can be attached to either the left or right side. When reeling in the fishing line, it is easy to perform reel operations such as palming by wrapping the reel in your hand, and it is safe without any danger.Moreover, the operability of the drag is not as constant as with the gear side. The purpose of this design is to make it possible to adjust the drag by easily rotating the handle in the forward or reverse direction, regardless of whether the handle is attached to the left or right side.

B. Structure of the invention [Means for solving the problem] In other words, the invention replaces handles at both left and right ends of the traverse cam shaft, which is interlocked and connected to the spool shaft by a gear transmission mechanism between the left and right side frames. In a drag mechanism for a double bearing reel, the drag mechanism is formed so that it can be mounted, has a built-in drag on the master gear side attached to the traverse cam shaft, and has a ratchet mechanism on the side plate a side of the master gear, The drag latch is provided on the traverse cam shaft, and the drag latch and the drag control screw are connected to each other via a moving means such as a cam or a screw so that the drag can be compressed or moved in the direction of decompression by forward or reverse rotation of the traverse cam shaft. A drag pawl pivotally supported on a side plate and a ratchet between the drag pawl and the traverse cam shaft to prevent rotation of the drag chute and the drag control screw by being removably engaged with the drag pawl. A reverse stopper pawl is rotatably supported on the side plate so that it can be engaged and detached, and a drag switch is rotatably supported on the side plate via a dead point spring so that it can be engaged and detached from the drag latch and ratchet. However, when the drag latch, which is integrated with the drag control screw, engages with the drag pawl due to the switching operation of the drag switch, the ratchet and the reverse stopper pawl do not engage, and in other cases, the drag latch and the drag pawl engage with each other. The above-mentioned problem has been solved by making it possible to selectively combine cases in which the ratchet and the reversing pawl can engage with each other.

〔Example〕

The embodiments of the present invention will be described below in detail based on the drawings. First, the double-bearing reel has a spool shaft 23 and a traverse cam shaft 3 of the level wind mechanism 2 with a bearing 4 interposed between the left and right side frames 1, 1. A ratchet 5 for preventing reverse rotation is fixed in the side frame 1 at one side end of the traverse cam shaft 3, and
A master gear 6 is rotatably loosely fitted, and a plurality of drag washers 7a... and a plurality of spring washers 7b... are attached to the traverse cam shaft 3 in the axial direction thereof. A drag 7 is built in, and both left and right ends 3a of the traverse cam shaft 3 are provided facing an opening 8 provided in the cover plate 1b of the side frame 1. A handle 10 is formed on both ends 3a of the traverse cam shaft 3 so that the handle 10 can be attached to the left and right sides interchangeably by connecting means 9 that can be easily attached and detached by means of a missing circular portion 9a and a set screw 9b. The spool shaft 23 and the spool shaft 23 are configured to be interlocked and connected to the master gear 6 via a gear transmission mechanism 24.

Here, the side frame 1 is formed hollow by fixing the cover plate 1b to the outside of the side plate 1a with screws 11, etc., and the ratchet 5, master gear 6, and drag are installed inside the side frame 1. 7. The gear transmission mechanism 24 is arranged.

The level wind mechanism 2 has a traverse cam 2a, a guide tube 2b, a thread guide and a slider (not shown), and the thread guide reciprocates in the left-right direction by the rotation of the traverse cam shaft 3, as is known. It is formed like this.

Thus, as shown in FIGS. 1 and 2, the drag mechanism of the present invention has a drag latch 12 in the side frame 1 near one end of the traverse cam shaft 3, and in the vicinity of one end of the traverse cam shaft 3. A moving means 13 is interposed therebetween so as to be able to reciprocate in the axial direction by rotating or reversing, and the moving means 13 includes cam means, screw means, etc., and the screw means is shown in the embodiment.

That is, as clearly shown in FIG. 2, a threaded portion 13a is carved on the outer periphery of the traverse cam shaft 3, and the drag latch 12 is screwed into the threaded portion 13a. Alternatively, as shown in the figure, the drag control screw 14 is screwed into the threaded portion 13a, and the drag latch 12 is inserted into the drag control screw 14. It may be fixed and integrated.

Also, within the side frame 1, the ratchet 5
On one side of the drag latch 12, a claw shaft 15 fixed between the side plate 1a and the cover plate 1b allows a drag claw 16 and a reverse stopper claw 17 to be freely engaged with the drag latch 12 and the ratchet 5, respectively. The claw portion 16a of the drag claw 16 is rotatably supported by the drag latch 12.
The drag pawl 16 is formed so as to be engaged in either normal or reverse rotation of the pawl shaft 1.
5, and has one end hooked to the side frame 1 etc. and the other end hooked to the drag claw 16.
As a result, it is elastically biased in the direction of engagement with the drag latch 12.

On the other hand, the pawl portion 17a of the reversal prevention pawl 17 is provided so as to engage with the ratchet 5 only when the ratchet 5 is reversed.

Furthermore, within the side frame 1, the drag claw 1
A drag switch 19 is pivotally attached to one side of the reverse stopper claw 17 and protrudes slightly outward from an opening (not shown) provided in the cover plate 1b, so that the drag switch 19 can be switched and operated using a boss 20. With a dead point spring 21 interposed by hooking one end to the side plate 1a and the other end to the drag switch 19.
It is elastically biased toward the ON/OFF switching position, and furthermore, the drag claw 16 and reverse stopper claw 1
Pressing portions 19a and 19b are provided on the 7 side, respectively, and the drag pawl 16 and reverse stop pawl 17
Contact pieces 16b and 17b protrude from the shaft support respectively.
and the above drag switch 19.
In the position shown in FIG. 1 when the switch is turned OFF, the pressing portion 19a presses the abutment piece 16b of the drag claw 16, and as a result, the drag claw 16 resists the elastic force of the drag claw spring 18 and drags the drag claw. 12
At this time, the reverse stopper pawl 17 is held rotatably around the pawl shaft 15, and when the handle 10 is reversed, it engages with the ratchet 5, causing the reverse rotation to occur. It is designed to prevent

Further, the drag switch 19, the drag pawl 16, and the reverse stop pawl 17 move the drag switch 19 to the first position.
The drag switch 19 is rotated in the direction of the arrow a from the OFF state shown in the figure to a position beyond the dead point of the dead point spring 21, and then the drag switch 19 is further rotated in the direction of the arrow a by the spring 21 and turned on. When the position is reached, the pressing part 19b presses the abutting part 17b, thereby rotating the reversing pawl 17 counterclockwise from the position shown in FIG. 1 to release the engagement with the ratchet 5, and the handle At this time, the other pressing part 19a is displaced counterclockwise from the position shown in FIG. 1, so that the contact part 16b
, the drag claw 16 is released from the drag claw spring 18.
is provided to stop the drag latch 12 from rotating in the forward or reverse direction.

Therefore, by rotating the traverse cam shaft 3 in the forward or reverse direction using the handle 10 in the above-mentioned ON state, the drag latch 12 is moved in the axial direction by the moving means 13, compressing the drag 7, and releasing the compression. Drag force can be adjusted arbitrarily.

Furthermore, after adjusting the drag force to the desired value, when the drag switch 19 is turned OFF and operated, the drag pawl 16 is removed from the drag clutch 12, and the drag switch 19 is turned off.
Since the fixation is released, rotation of the handle 10 causes the drag latch 12 to rotate together with the traverse cam shaft 3, and the drag force is maintained at a desired value that has been adjusted in advance.

Here, when screw means is adopted as the moving means 13, the threaded portion 13a may be either a left-hand thread or a right-hand thread.

FIG. 3 shows another embodiment of the present invention.

In this embodiment, the drag claw 16, the reverse stopper claw 17, and the drag switch 19 are shafted by a common shaft 15', which is provided by coaxially disposing the claw shaft screw 15 and the boss 20 in the previous embodiment. The other parts are the pressing parts 19a, 19b and the contact part 16.
Although the positional relationship between b and 17b is different from that of the previous embodiment, its function is the same as that of the above embodiment.

In addition, in FIGS. 1 and 3, 22 indicates a clutch.

[Effect of idea]

As explained above, the drag mechanism of the double-bearing reel according to the present invention is constructed so that the handle 10 can be attached interchangeably to both the left and right ends of the traverse cam shaft 3, and
A dual-handle dual-bearing reel with a built-in drag 7 on the side of the master gear 6 attached to one end of the traverse cam shaft 3, in which the rotating body such as the drag handle protrudes outward from the reel body as in the conventional example. Therefore, even if the handle 10 is attached to either the left or right side, it is easier to perform palming, etc., and there is less risk of getting your fingers caught in the rotating body, making it safer. Also, in terms of drag operability, it is better than the conventional example. Since the drag handle does not have to be placed on the gear side, there is no problem in attaching the handle 10 to either the left or right end of the traverse cam shaft 3, and after switching and operating the drag switch 19. By simply turning the handle 10 in the forward or reverse direction as desired, the drag force can be adjusted quickly in response to fish movements, etc., and the desired value of the drag force can be easily obtained.
