Description

[Detailed Description of the Invention] The present invention relates to a drag mechanism for a spinning reel for fishing.

Conventionally, in the above-mentioned reel, the spool is fixed to the main shaft, and the rotor is slip-rotated with respect to the spool, and when the fishing line is released, the rotor is slip-rotated by the drag operation to untwist the fishing line. A device that is released in a state in which it is released is being implemented.

However, according to the above-mentioned conventional reel drag mechanism, both in the case of an open drag and when the drag force is minimized, it is not possible to apply rotational force to the rotor by operating the handle attached to the ratchet shaft. Automatic locking cannot be performed when reversing the bail arm from the fishing line release state to the reeling state, so manual operation must be performed each time, or the drag knob must be tightened when automatic locking is performed. Therefore, when using it as an oven drag, the drag knob had to be further loosened, making it extremely difficult to use.

However, regardless of the strength of the drag force, a drag mechanism that can transmit rotational force to the master gear, that is, the rotor by operating the handle in the forward or reverse direction, was proposed by the applicant and is related to the earlier application. According to such a drag mechanism, for example, if the drag was set to slip at 500 g, even if a 400 g fish was caught, the drag would slip due to the resistance of the fishing line guide, making it impossible to wind up the fishing line.

The present invention was developed in consideration of the above-mentioned circumstances, and was developed in such a way that the drag force is increased by rotating the handle in the forward direction (in the direction of winding up the fishing line).
The fishing line can be reeled in even if there is a fish with a weight that corresponds to the pre-adjusted drag force, and the drag force can be quickly adjusted by rotating the handle in the opposite direction.For example, even in cases where excessive tension is applied, etc. It has a drag mechanism that allows immediate response.

The drawings showing an embodiment of the present invention will be described in detail below. In FIG. 1, a pinion 2 of a tube shaft that rotatably supports a rotor (not shown) on a main body 1;
A master gear 6 of a ratchet shaft 5 rotatably supported via a bearing 4 is engaged with the boss portion 3a of the lid 3 screwed to the main body 1, and this master gear 6 is provided at the inner end of the ratchet shaft 5. A washer 8 is interposed between the cup-shaped ratchet 7 and the disc portion 10 provided at the inner end of the drag shaft 9, which is inserted into the ratchet shaft 5. A plurality of drag washers 11 and spring washers 12 are interposed in a layered manner.

Thus, the drag mechanism A of the present invention, as shown in FIG. 14, with a drag spring 15 interposed between the ratchet shaft 5
A cam boss 16 is slidably supported in the axial direction and fixedly supported in the periaxial direction at the end, and a handle boss 17 is mounted on the protruding end of the drag shaft 9 that protrudes from the end of the ratchet shaft 5, and a spring is attached to the handle boss 17. It is rotatably supported in a fixed position by a nut 19 through a washer 18, and a torsion spring 20 is interposed between the handle boss 17 and the cam boss 16 to rotate the handle 21 in the normal rotation direction, that is, in the fishing line winding direction. It is biased to be repellent.

Then, the cam boss 16 and handle boss 17
As shown in FIGS. 2 to 4, on the opposing surfaces of the A cam 23 consisting of inclined surfaces 23b, 23b that slope upward in the forward rotation direction of the handle is provided between the portions 23a, 23a and engaged with each other.
As shown in FIG. 2A, the inclined surfaces 23b, 23b
The handle 21 is elastically biased in the upward direction, that is, in the forward rotation direction of the handle, thereby eliminating play in the handle 21 and holding the handle at a constant position.

Here, the mounting hole 16a of the cam boss 16 is formed in the same oval shape as the cross-sectional shape of the ratchet shaft 5, so that they can move relative to each other in the axial direction.
It is fixed in the axial direction.

Further, a coil spring is used as the torsion spring 20, and the end portion is connected to the cam boss 16 and the handle boss 2.
According to the illustrated example, the cam 23 is provided on a cam boss 16.

That is, the protrusions 23a, 23a and the inclined surface 23b,
23b are provided at two symmetrical positions.

In the above configuration, when the handle 21 is rotated in the forward direction, the protrusions 22, 22 of the handle boss 17 slide on the inclined surfaces 23b, 23b of the cam 23, and the second
As shown in figures A to B, the inclined surfaces 23b, 23b
move to a high place. Therefore, the cam boss 16 compresses the drag spring 15 by the slope amount h of the inclined surfaces 23b, 23b, and moves to the right in FIG.
The compressive force is transmitted to the drag shaft 9 through the handle boss 17, and the disc portion 10 compresses the drag washer 11 and spring washer 12, thereby increasing the drag force.

The fishing line is wound in such a state,
If the pull of the fish becomes strong and excessive tension is applied to the fishing line, rotate the handle 21 in the opposite direction.
Since the protrusions 22, 22 of the handle boss 17 move to the lower parts of the inclined surfaces 23b, 23b of the cam 23, the drag spring 15 causes the cam boss 16 to move on the ratchet shaft 5 to the left in FIG. , 23b by the amount of gradient h, the drag washers 11,
The amount of compression of the spring washer 12 becomes smaller,
As a result, the drag force decreases.

Further, fine adjustment of the drag force is performed by screwing the drag knob 14 forward and backward.

As explained above, according to the drag mechanism of the spinning reel for fishing according to the present invention, when the handle 21 is rotated in the forward direction to reel in the fishing line, the drag force is adjusted in advance to the desired drag force by the drag knob 14. By the cam 23 of the cam boss 16, the cam boss 16 compresses the drag spring 15 and moves.
Since the drag force increases, it is possible to reliably wind up the fishing line under the pre-adjusted drag force.Also, if excessive tension is suddenly applied to the fishing line during winding, use the handle 21.
By rotating the drag force by a certain angle in the opposite direction, the drag force can be instantaneously lowered, allowing a quick response to prevent fishing line breakage, etc. Furthermore, the drag can be adjusted by using the drag knob 14 separately from the handle 21. Furthermore, since the handle 21 is resiliently biased in the forward rotation direction by the torsion spring 20, the forward rotation can be performed independently as described above.
Although the rotation is reversible, the handle 21 does not rattle during forward rotation, making it easy to operate the handle and providing excellent convenience.
