Description

[Detailed explanation of the invention] (Field of industrial application) This invention relates to fishing reels, specifically spinning reels in which a flyer equipped with a bail rotates by the rotation of a handle, and a spool reciprocates back and forth in the axial direction. Regarding reels.

(Prior art) The drag mechanism in conventional spinning reels is a spool drag that is performed by keeping the flyer stationary and rotating the spool.The strength or weakness of the braking force that acts on the reverse rotation of the spool can be adjusted by adjusting the drag on the front of the spool. This is done by operating a knob or an adjustment dial at the rear of the gearbox.

(Problem to be solved by the invention) When fishing with a spinning reel equipped with the above-mentioned spool drag, there is a fishing method in which the fish is caught while interacting with the hooked fish, that is, the pull of the hooked fish is strong. If this is the case, weaken the drag force so that the fishing line is reeled out by the pull of the fish, and when the movement (pull) of the fish becomes slow, increase the drag force to forcibly reel the fishing line. Front drag and rear drag like this have the disadvantage that it is difficult to respond quickly.

In addition, with a spool drag, the spool around which the fishing line is wound slips against the reel shaft when the flyer equipped with the bail is stationary, so the spool slips and the fishing line that is fed out does not move as it is being reeled in. The problem is that the fishing line tends to twist because it slips in a fixed position instead of unraveling by following the opposite direction.

The present invention was developed in view of the problems of the conventional technology as described above, and its purpose is to allow the fishing line to be paid out and reeled in according to the pull of the fish hooked on the bait without causing the line to twist. To provide a fishing reel that can be used for fishing.

(Means for Solving the Problems) In order to achieve the above object, the fishing reel of the present invention has a fishing reel in which a flyer equipped with a bail rotates by rotation of a handle, and a spool reciprocates back and forth in the axial direction. This is a rotating spinning reel, in which a hollow main gear shaft is rotatably supported between the side plates of a gear box, and a main gear having a circular hole bored in a non-circular shaft portion of the main gear shaft having an oval or other external shape can freely rotate. At the same time, drag washers constituting the drag mechanism are disposed on both sides of the main gear in the axial direction, and the drag mechanism is mounted on the main gear shaft.

Further, an intermediate shaft is fitted and freely rotated inside the circular hole of the main gear shaft, and a handle shaft is fitted and engaged with the intermediate shaft so that it can rotate integrally.
A drag screw is engaged and integrated with the outer side of the intermediate shaft in the axial direction.

A drag nut is screwed onto the outside of the drag screw, and the drag nut is engaged with a non-circular shaft portion of the main gear shaft to prevent rotation.
It can be moved along the axial direction by rotating the drag screw.

Also, one end of the drag nut in the axial direction can be moved toward and away from the washer of the drag mechanism so that a pressing force acts directly on the washer group, or a bearing or a bearing is provided between the drag nut and the drag washer.
It is also possible to press indirectly through a pressing force transmitting member such as a drag sleeve.

(Function) The drag nut screwed into the drag screw of the intermediate shaft, which rotates as the handle rotates, is partially engaged with the main gear shaft and is prevented from rotating, so the handle shaft cannot be rotated in the forward or reverse direction. By rotating, the drag nut slides along the axis on the outside of the main gear shaft, pressing the drag washer directly or indirectly through the bearing and drag sleeve, and applying pressure to the drag washer. becomes weak.
That is, when the handle is rotated in the positive direction (fishing line winding method), the drag nut slides and presses the drag washer, and the main gear is integrated with the main gear shaft via the drag washer, resulting in a forced winding state. becomes. When the handle is rotated in the opposite direction, the drag nut slides in a direction that releases the pressure on the drag washer, and if a tension greater than the frictional engagement force that holds the main gear in a unitary rotation is applied to the fishing line, the flyer will rotate in the opposite direction. It becomes possible.

The strength of the frictional engagement force applied to the main gear can be adjusted by rotating the handle in the forward direction to increase the strength, and by rotating the handle in the reverse direction to decrease the strength.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a gearbox with left and right side plates 1a, 1.
A main gear shaft 2 is rotatably supported on the shaft 2, and a projecting edge 3 is provided on the outer peripheral surface of the shaft 2 in the middle in the longitudinal direction. A main gear 4 is fitted to the outside of the oval-shaped non-circular shaft portion 2a to freely rotate, and drag washers 5 are disposed on both sides of the main gear 4. , so that the main gear 4 is clamped.

Further, an intermediate shaft 6 having a circular outer shape in cross section is inserted into the inside of the main gear shaft 2, and the non-circular shaft portion 2a side is extended and protruded outward to make it larger in diameter than the inner diameter of the main gear shaft 2.
One half of the protruding portion is slotted into an oval cross-section to form an engaging shaft portion 6a, and a drag screw 7 is fitted and engaged with the engaging shaft portion 6a so as to be freely rotatable. The thread shape formed on the outer peripheral surface of the drag screw 7 is the oval-shaped shaft portion 2 of the main gear shaft 2.
A drag nut 9 is fitted between the outer surface and the cylindrical portion 8 of the side plate 1a, is engaged with the oval shaft portion 2a to prevent rotation, and is slidable in the axial direction. A bearing 10 and a drag sleeve 11 are interposed between the drag washer 5 and the drag washer 5. The drag sleeve 11 has a circular outer shape, has an oval hole 11a in the center that engages with the non-circular shaft portion 2a, and is formed to rotate integrally with the main gear shaft 2 and to be slidable in the axial direction. Further, an engaging protrusion 12 is protruded from the surface of the drag sleeve 11 facing the drag washer 5 and is located on the diametrical line. It is fitted into a notch 14 continuous to an oval hole of a non-return gear 13 which is fitted to rotate integrally therewith, and is connected to the drag washer 5.

Inside the intermediate shaft 6 described above, there is a handle shaft 15 with a square shaft that matches the square hole (square hole).
is inserted, and one side of the handle shaft 15 is integrally connected and fixed to a shaft receiver 16 by insert molding, and a handle arm 17 is foldably connected to the shaft receiver 16. A screw hole 18 is formed in the axis of the other side, and a shaft set screw 19 can be screwed therein. Therefore, by removing the shaft set screw 19, the handle shaft 15 can be removed.
can be freely removed from the intermediate shaft 6, allowing the handle to be replaced between the left and right sides.

In the figure, 20 is a coil spring that prevents the handle from wobbling when the drag is free. To prevent the handle from wobbling, the side end of the non-circular shaft portion 2a of the main gear shaft 2 and the intermediate portion protruding outward from the non-circular shaft portion 2a are used to prevent the handle from shaking in the forward and reverse directions. Although a gap is formed between the enlarged shaft portion of the shaft 6, if the coil spring 20 is not interposed between the shaft receiver 16 and the drag screw 7 engaged with the intermediate shaft 6, the fishing rod At the time of transfer, the intermediate shaft 6 is pushed by the side end of the shaft receiver 16 and moved by the previous distance, and the intermediate shaft 6 and main gear shaft 2 come into contact, producing a rattling metallic sound. Note that the looseness (play) is not large enough to provide support for forward and reverse rotation of the handle.

Therefore, as described above, the coil spring 20 is elastically mounted between the shaft receiver 16 and the drag screw 7, so that the shaft receiver 16 is urged outward by the tension of the coil spring 20. Pull the intermediate shaft 6 toward the shaft receiver 16 via the handle shaft 15 and the shaft set screw 19, and then tighten the intermediate shaft 6.
This means that the main gear shaft 2 and the main gear shaft 2 are held tensioned so that they do not collide. Thereby, it is possible to prevent the occurrence of rattling noises even when the fishing rod is transferred.

In the figure, 21 is a pinion gear, a flyer (not shown) is integrally connected and fixed to the part of this pinion gear that protrudes from the gear box by tightening a nut, and a spool (not shown) is attached to the tip of the reel shaft 22 that passes through the pinion gear 21. omission)
are connected and fixed. Further, 23 is a check claw, 24 is a parallel winding gear, 25 is a slider, and 26 is a clip ring.

With the above configuration, when the handle arm 17 is rotated in the forward direction, the handle shaft 15, intermediate shaft 6, and drag screw 7 are engaged and rotated as one body, and the drag nut 9 that is screwed into the drag screw 7 is prevented from rotating. Therefore, it moves to the right on the outer peripheral surface of the main gear shaft 2 along the axis,
By pressing the bearing 10 and the drag sleeve 12, the drag washer 5 is further compressed, increasing the surface pressure (frictional force) acting on the main gear 4, and the fishing line can be forcibly reeled in ( (See Figure 5).

Conversely, when the handle arm 17 is rotated in the opposite direction from the state shown in FIG. The surface pressure (frictional force) that had been
is capable of slip rotation with respect to the main gear shaft 2, and the braking force that is applied during the slip rotation is variably adjusted by the amount of reverse rotation of the handle arm.

Therefore, while holding the handle arm 17,
By rotating the handle arm 17 in the forward and reverse directions, the drag force (braking force) can be variably adjusted and can be quickly operated depending on the fishing situation.

(Effects of the invention) As detailed above, the fishing reel of the invention has the following features:
The drag nut screwed into the drag screw of the intermediate shaft, which rotates integrally with the handle shaft, is prevented from rotating and slides in the axial direction to press or release the drag washer installed on the main gear. When rotated in the positive direction, the drag nut moves along the axial direction and presses the drag washer, integrating the main gear with the main gear shaft by surface pressure, resulting in a forced winding state. Conversely, when the handle arm is rotated in the opposite direction, the surface pressure that makes the main gear engage and integrate becomes weaker, and when a reverse rotation force that is greater than the drag force is applied, the flyer will be reversed, and when the reverse rotation occurs, the The applied braking force can be variably adjusted by the amount of reverse rotation of the steering wheel.

Therefore, it is possible to forcibly reel in and reverse the slip simply by rotating the handle, and the braking force when reversing the slip can also be variably adjusted in a stepless manner, so the fishing line can be reeled in according to the degree of pull of the hooked fish, etc. You can quickly respond to operations such as lifting or pulling out. Further, the handle arm can be changed to left-handed or right-handed by removing the set screw and replacing the handle shaft. Furthermore, since the drag effect does not act on the reversal of the spool as described above, but on the reversal of the flyer, the fishing line is less likely to be twisted, allowing you to enjoy stable fishing.
