Description

[Detailed Description of the Invention] The present invention relates to a drag assist 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 in which the device is released in a state in which it is released is currently in use.

However, the drag mechanism A of the conventional reel mentioned above
As shown in FIG. 1, a bearing 19 is interposed between a pinion 4 of a tube shaft 3 that rotatably supports a rotor 2 on a main body 1, and a boss portion 5a of a reel housing 5 screwed to the main body 1. The master gear 7 of the ratchet shaft 6 rotatably supported is engaged with the ratchet shaft 6, and the master gear 7 is fitted with a cup-shaped ratchet 8 provided at the inner end of the ratchet shaft 6 with a washer 9 interposed therebetween. , furthermore, a disk portion 11 at the inner end of the drag shaft 10 inserted into the ratchet shaft 6;
A plurality of drag washers 12 and spring washers 13 are interposed in a layer between the master gear 7 and the drag knob 15 by forming a threaded portion 14 at the end of the drag shaft 10 protruding from the ratchet shaft 6. , bush 16 and set screw 17
Since the rotor is screwed through the latchet shaft 6, rotational force can be transmitted to the rotor 2 by operating the handle 18 attached to the ratchet shaft 6, both in the case of an open drag and when the drag force is minimized. Therefore, it is not possible to perform automatic kick when reversing the bail arm from the fishing line release state to the reeling state, and therefore, the bail arm must be reversed by manual operation each time. In addition, since it is necessary to tighten the drag knob when using the auto-kick, the drag knob must be loosened again when using the open drag, which is extremely difficult to use.

Therefore, in a spinning reel equipped with the above-mentioned drag mechanism A, the present applicant has developed a drag auxiliary mechanism that allows rotational force to be transmitted to the master gear, that is, the rotor, by operating the handle in forward or reverse directions, regardless of the strength of the drag force. The present invention is a further improvement of the above-mentioned drag assist mechanism, and its purpose is to provide an automatic locking system with an open drag and minimal drag force. The drag knob pressure force can be automatically released.

The drag assisting mechanism B of the present invention will be described in detail below with reference to the actual drawings. In FIG.
The spring holder 22 is formed in the polygonal part 20, and the projections 24 are formed in the fitting hole 23 as shown in FIG. The same number of handle bosses 25 are provided, and the handle bosses 25 are provided in the threaded portion 21 in the direction indicated by the arrow a in FIG. They are screwed together so that they rotate toward the drag knob 15 side by forward rotation (in the fishing line winding direction), and
A drag assisting member 26 is interposed between the spring holder 22 and the drag knob 15. The drag auxiliary member 26 uses a compression spring 26a and a washer 26b in the illustrated example, but a spring washer or the like may be used instead.

Further, the spring holder 22 and the handle boss 25 are connected by a torque spring 27.

That is, a coil spring is applied as the torque spring 27. This torque spring 27
has one end 27a hooked to an engagement hole 22a drilled in the spring holder 22, and the other end 27b hooked to an engagement hole 25a drilled in the handle boss 25, and in this state, it cannot be pressed against the drag knob 15. The pressure still doesn't work. As shown in Figure 2, each engagement hole 2
It is preferable to assemble them by applying a twisting torque force to the extent that looseness in the fitting between the torque springs 2a and 25a and the torque spring 27 is removed.

In Fig. 1, 28 is the main shaft;
Reference numeral 9 indicates a reversal prevention pawl that engages with the ratchet 8.

Therefore, in the above configuration, the drag assist mechanism B
is operated independently of the adjusted state of the drag. Therefore, if the handle 18 is quickly rotated in the normal rotation direction shown by arrow a in FIG. 2 with the drag adjusted very weakly, the handle boss 25 will be The engagement hole 25 formed in the handle boss 25 is rotated forward on the screw 21 of the ratchet shaft 6 due to the slight frictional resistance and inertia of the bearing on the ratchet shaft.
End 27 of torque spring 27 hooked to a
Since twisting force is applied to a and 27b and this rotational force is activated, the torque spring 27 is also slightly distorted and rotates together with the spring holder 22 by the angle β shown in FIG. The master gear 7 moves in the direction of the drag knob 15 by screwing through the auxiliary member 26 and tightens the drag via the auxiliary member 26, thereby increasing the drag force and attempting to rotate the master gear 7 in order to reverse the not-illustrated tightening lever of the rotor 2. The bail arm reversing force acts as a stationary force on the rotor 2, and the handle boss 25 further spirals and twists the torque spring 27 in the spring holder 22 to strengthen the drag force and reverse the not-shown twist lever. On the other hand, twisting torque is stored in the torque spring 27 and is used to reverse and return the handle 18.

Therefore, when the bail arm (not shown) is tilted down with an open drag to return the fishing line from the fishing line release state to the fishing line reeling state, the automatic locking can be performed simply by rotating the handle 18 in the forward direction. , no drag operation is required at that time.

When the forward rotation of the handle 18 is released after the above-mentioned auto-kick, the torque spring 27 has stored torsional torque during the forward rotation of the above-mentioned handle, so the handle 18 is returned in the reverse direction by the elastic return of the torque spring 27, and the handle boss 25 screws in the direction away from the drag knob 15,
The pressing force on the drag knob 15 can be released to create an open drag, and when the drag is opened, the torque force of the torque spring 27 will be in the initial setting state.

As explained above, the drag auxiliary mechanism according to the present invention includes the drag mechanism A formed by inserting the drag shaft 10 into the ratchet shaft 6 to which the handle 18 is attached, and which is fixed to the main shaft when releasing the fishing line. In a spinning reel in which the rotor slips against the spool, the handle 18
Since the rotational force can be transmitted to the master gear 7 by the forward and reverse operations of the rotor 2, when the drag force is set to an open drag or the drag force is minimized, a kicking force for reversing the bail arm can be applied to the rotor 2 to perform automatic kicking. In addition, especially according to the present invention, by releasing the support for the handle after auto-kick, the torque spring 27 allows the handle 18 to return to reverse rotation and automatically return to open drag, so that the handle cannot be operated in reverse. This has the effect of further improving the functionality and operability of this type of mechanism.
