Description

Fly fishing reel with compound drag mechanism {FLY FISHING REEL HAVING COMPOSITE DRAG MECHANISM}

The present invention relates to a fly fishing reel, and more specifically, to a fly fishing reel having a drag mechanism that can adjust the drag force of the spool.

Fly fishing usually involves pre-releasing the fishing line from a fly fishing reel, collecting it under the angler's feet on board or on the beach, then throwing the fishing line. Thus, the fly fishing reel performs a storage function of storing a considerable amount of fishing line wound around it. In addition to this storage function, a drag is provided as the fishing line is released from the reel spool, allowing the angler to adjust the action when retrieving the fish caught in the fishing line.

This drag is also used to resist the loosening of the fishing line by the fish, preventing the fish from getting tired quickly or running away from the fish at very long distances. When used in this manner, it is preferable to adjust the amount of drag torque and to smoothly perform the drag action. In the simplest reels, the same amount of drag is applied to both reels of rotation, and on more complicated reels, the spool when the angler is unrolled from the reel, rather than the drag to the direction of rotation. Greater drag is given for the direction of rotation.

Drag mechanisms are generally divided into two types. One type is to use a pawl that engages a ratchet gear attached to a rotating spool. Such a mechanism has proved difficult to adjust in most instances because it does not impose a smooth torque resistance on spool rotation. Another type is to use friction of a disk or pad against a rotating spool or a member that rotates with the spool. This friction drag mechanism incorporates a type of coupling that allows the drag to operate only when the fishing line is released from the spool. In such a disc drag mechanism, water or oil accumulated on the surface of the pad during operation severely deforms the drag setting to change the torque or cause it to operate unevenly.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the conventional drag mechanism.

Another object of the present invention is to provide a new concept of a drag mechanism that utilizes both the principle of a type of drag mechanism using a pole and the type of a drag mechanism of friction type.

In order to achieve the above object, according to the present invention, in a fly fishing reel having a reel frame and a spool rotatably mounted about a shaft within the reel frame, mounted on the shaft to rotate with the spool A cam member shot upwardly by the shot member; A ratchet gear disposed coaxially with the cam member and below; A first drag mechanism frictionally engaged with the teeth of the ratchet gear; And a second drag mechanism disposed below the ratchet gear. According to this, when the spool rotates in the direction in which the fishing line is released, the ratchet gear is rotated by the cam member moved downward, whereby the first and second drag mechanisms are operated.

The cam member consists of an upper and lower cam member formed to engage with each other, and the lower cam member is formed to co-rotate with the spool. The upper cam member has a cam-like protrusion that is radially opposed to the lower surface thereof and has a right-sided triangular cross section extending obliquely downward. The lower cam member includes a contact portion in contact with a right angle portion of the cam-shaped protrusion of the upper cam member, a slide portion in contact with the inclined portion of the cam-shaped protrusion, and an engagement boss engaged with the bridge portion of the ratchet gear.

The first drag mechanism includes a pawl arranged to frictionally engage the teeth of the ratchet gear to impart rotational resistance to the ratchet gear when the spool rotates in the direction in which the fishing line is released and to generate a click sound; A spring is provided to impart a constant elasticity to the pole.

The second drag mechanism includes a friction plate having a engaging piece engaged with the bridge portion of the ratchet gear so as to co-rotate with the ratchet gear, a lining washer that imparts rotational resistance to the friction plate, and a drag plate whose height can be adjusted in the axial direction. Equipped.

Hereinafter, a fly fishing reel having a compound drag mechanism according to the present invention will be described in detail with reference to the embodiment shown in the drawings.

Typically, a fly fishing reel is composed of a reel frame and a spool rotatably mounted within the reel frame. However, FIG. 1 schematically shows a reel frame without the spool shown. It should be noted that the reel shown in the figures is designed for right handed handling.

Inside the hollow cylindrical portion of the spool 50, the shaft 12 is inserted in the axial direction, as shown in Figs. The shaft 12 is provided with a compound drag mechanism using both a gear type and a friction type. This drag mechanism has a pair of cam members 24, 26 inserted inside the hollow cylinder portion of the spool so as to co-rotate with the spool. These cam members 24 and 26 are coaxially mounted to the shaft 12.

The upper cam member 24 has a diameter approximately equal to the diameter of the bearing 22 mounted just above the member 24. The upper cam member 24 has a cam-like protrusion 24a that is opposite to the bottom surface in the radial direction and has a right-sided triangular cross section extending obliquely downward.

The lower cam member 26 has a contact portion 26b in contact with a right angle portion of the cam-shaped protrusion 24a of the upper cam member 24, and a slide portion 26c in contact with an inclined portion of the cam-shaped protrusion 24a. Have The lower cam member 26 also has an engagement boss 26a that engages with the bridge portion 20a of the ratchet gear 20.

It should be noted that the above-described upper and lower cam members 24 and 26 are shot upwards at all times upwards by the spring 21 disposed on the ratchet gear 20. That is, in the state where the spool is free to rotate, the lower cam member 26 is not in contact with the ratchet gear 20 at all.

The ratchet gear 20 is in frictional contact with the pawl 36 which is always deflected by the spring 34. Therefore, when the ratchet gear 20 rotates, the pole 36 comes into contact with the teeth of the ratchet gear to provide a drag force in the rotational direction of the ratchet gear and generate a click sound. The direction of rotation of the ratchet gear to which the drag force is applied can be selected by adjusting the direction of the spring force of the spring 34 imposed on the pawl 36. For example, the pawl shown in FIG. 1 is arranged to impose a drag force when the ratchet gear 20 rotates clockwise. In this embodiment, the spring force adjustment of the spring 34 depends on the arrangement direction of the spring fixing arm 32.

Below the ratchet gear 20, the friction plate 40, the lining washer 42, and the drag plate 44 are arranged coaxially. The friction plate 40 has a engaging piece 40a that engages with the bridge portion 20a of the ratchet gear so as to co-rotate with the ratchet gear 20. The drag plate 44 may adjust the friction force between the friction plate 40 and the lining washer 42 by a drag adjustment nub 15 provided on the outer surface of the reel frame 10. This gram adjustment nub 15 is screwed into the screw hole 37 of the drag plate 44 via the washer 17 and the hole 19 of the reel frame 10. An upper end of the threaded shaft of the drag adjustment nub 15 is provided with a female threaded opening 16, in which a bolt and a nut are fastened to prevent the drag adjustment nub 15 from escaping from the reel frame.

The operation of the fly fishing reel having a compound drag mechanism according to the present invention described above will be described in detail.

2 is a cross-sectional view schematically showing a state in which the spool rotates clockwise, that is, the fishing line is wound. In this state, since the contact portion 26a of the lower cam member 26 is in contact with the right angle portion of the upper cam member 24, the upper cam member 24 is rotated by the lower cam member 26. At this time, since the lower cam member 26 is shot upward by the spring 21, the engagement boss 26a of the lower cam member 26 does not contact the bridge portion 20a of the ratchet gear 20. Not in free state. Therefore, when the spool rotates clockwise, the ratchet gear 40 does not rotate.

3 is a cross-sectional view schematically showing the state when the spool rotates counterclockwise, that is, the fishing line is released. In this case, the slide portion 26c of the lower cam member 26 moves along the inclined portion of the upper cam member 24 so that the engaging boss 26a of the lower cam member 26 moves the ratchet gear 20. Is in contact with the bridge portion 20a. When the lower cam member rotated by the spool contacts the ratchet gear, the ratchet gear also rotates.

The ratchet gear 20 is in constant engagement with the pawl 36 and the engaging piece 40a of the friction plate 40 that are shot by the spring 34. Therefore, when the ratchet gear 20 rotates, the ratchet gear is subjected to a constant drag force by the pawl. Since the drag force by the pawl is determined by the spring force of the spring 34 connected to the pawl, it cannot be adjusted separately during the use of the reel.

In addition, the ratchet gear 20 rotates the friction plate 40 provided below the gear. The friction plate 40 is subject to rotational resistance by friction with the lining washer 42 interposed between the friction plate and the drag plate 44. This rotational resistance is transmitted to the spool 50 via the ratchet gear 20 and the lower cam member 26.

While the right handed fly fishing reel has been described so far, it should be noted that the left handed fly fishing reel can be provided if the inclined portion and the slide portion of the cam member are formed in the opposite directions as shown in the drawings.

According to the above-described configuration, the fly fishing reel according to the present invention can use both the gear type and the friction type drag mechanism by contacting the ratchet gear and the friction plate.
