Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly, to a spinning reel mounted on a fishing rod and winding a fishing line around an axis of the fishing rod.

[0002]

2. Description of the Related Art A spinning reel generally has a reel body having a handle, a spool mounted on the reel body so as to be movable back and forth, for winding a fishing line around an outer periphery, a rotor for guiding the fishing line to the spool, and a handle for the rotor. And an oscillating mechanism for rotating the spool back and forth in synchronization with the rotation of the rotor.

The spool has a cylindrical bobbin trunk, a large-diameter flange disposed at the front of the bobbin trunk, and a skirt integrally formed at the rear of the bobbin trunk. In general, when a fishing line made of a nylon material is used, the bobbin trunk is often formed in a tapered cylindrical shape so that the fishing line is released without resistance during casting. However, when a fishing line made of a high-strength polyethylene material is used, some of the fishing line is formed in a thick tapered cylindrical shape in order to prevent a backlash phenomenon in which the fishing line is released at one time during casting.

The oscillating mechanism includes a mechanism for moving a spool back and forth by rotation of an oscillating gear, a screw shaft that rotates in conjunction with a rotor, and a slider that engages with the screw shaft and moves back and forth. There is a cam type. The traverse cam type has a small change in speed at the time of forward / backward movement and has a stable thread winding shape. In the traverse cam type oscillating mechanism, the spool is moved back and forth via a spool shaft mounted on the slider so as not to move in the axial direction.

[0005]

In the conventional spinning reel spool, the shape of the bobbin trunk must be properly used depending on the material of the fishing line, and the management of the spool is troublesome. Therefore, it is conceivable to configure the bobbin trunk with a straight cylinder, that is, a cylinder having an outer peripheral surface parallel to the axis. However, in a spinning reel configured to move the spool back and forth by a traverse cam type oscillating mechanism, simply forming the bobbin trunk with a straight cylindrical body may result in a bobbin shape that bulges at both ends of the bobbin trunk. There is. This is because, in the case of the traverse cam type oscillating mechanism, the front and rear movement speed of the spool is constant in the bobbin shape at the intermediate portion of the bobbin trunk, but the speed gradually decreases at both ends to change the direction. . To prevent this, a technique in which the bobbin trunk is formed in an arc shape bulging outwardly is disclosed in Japanese Patent Application Laid-Open No. 57-16633. When the bobbin trunk is formed in an arc shape in this way, when the spool is moved back and forth by the traverse cam type oscillating mechanism, the intermediate portion of the bobbin trunk tends to have a swollen bobbin shape.

SUMMARY OF THE INVENTION An object of the present invention is to provide a spinning reel having a traversing cam type oscillating mechanism, in which a spool wound on a spool is flattened along an axis.

[0007]

A spinning reel according to a first aspect of the present invention is a reel mounted on a fishing rod and winding a fishing line around an axis along the axis of the fishing rod.
The vehicle includes a spool, a rotor, a rotor drive mechanism, and an oscillating mechanism. The reel body has a handle and is mounted on a fishing rod. A spool body having a circumferential surface parallel to the axis and a pair of tapered surfaces that gradually decrease in diameter from both ends of the circumferential surface, around which a fishing line is wound;
A front flange portion provided at a front portion of the bobbin trunk portion, and is mounted on the reel body so as to be movable back and forth. The rotor is rotatably mounted on the reel body and guides the fishing line to the spool. The rotor drive mechanism transmits the rotation of the handle to the rotor. The oscillating mechanism has a screw shaft that rotates in synchronization with the rotation of the rotor, and a moving member that engages with the screw shaft and moves back and forth, and moves the spool back and forth.

In this spinning reel, when the handle is rotated in the line winding direction, the spool moves forward and backward and the rotor rotates, so that the fishing line is uniformly wound around the spool. At this time, the speed gradually decreases due to the direction change at the forward end and the backward end of the spool. For this reason, more fishing line is wound around this portion than at other portions. Therefore, a tapered surface with a gradually decreasing diameter is formed in this portion so that the outer peripheral side does not bulge in a bump-like manner even if a large amount of fishing line is wound around this portion. For this reason, even if the spool is moved back and forth by the traverse cam type oscillating mechanism, the spool shape of the spool can be flattened along the axis.

The spinning reel according to the second aspect of the present invention is the spinning reel according to the first aspect.
, The axial length of the circumferential surface is in the range of 25% to 75% of the axial length of the entire bobbin trunk. In this case, since the length of the tapered surface is larger than that of the circumferential surface, the shape of the thread can be flattened even if the speed changes gently. The spinning reel according to the third aspect is the spinning reel according to the first or second aspect.
, The minimum diameter of the tapered surface is in the range of 90% to 99% of the maximum diameter.

A spinning reel according to a fourth aspect of the present invention is a spinning reel according to the first aspect.
The diameter of the circumferential surface is at least 55% of the diameter of the front flange portion, and the axial length of the bobbin trunk is at least 45% of the diameter. In this case, since the diameter of the bobbin trunk portion of the spool is 55% or more of the diameter of the front flange portion and the axial length of the bobbin trunk portion is 45% or more of the diameter, the diameter of the bobbin trunk portion is reduced. It becomes relatively large, making it difficult for the fishing line to have a winding habit. Also,
At the time of casting, the diameter of the bobbin trunk is relatively large with respect to the front flange portion. Therefore, even when the bobbin trunk is in a straight shape parallel to the axis, the discharge resistance is small.

A spinning reel according to a fifth aspect of the present invention is a spinning reel according to the first aspect.
In the reel according to any one of Items 1 to 4, the front flange portion is inclined forward toward the outer periphery and has an inclination angle of 7 degrees or less. In this case, since the front flange portion is inclined slightly forward from the vertical, the fishing line is more smoothly released, and the fishing line is less likely to be released from the front flange at one time, so that backlash can be further prevented.

A spinning reel according to a sixth aspect of the present invention is a spinning reel according to the first aspect.
6. The reel according to any one of items 1 to 5, wherein the rotor is
A cylindrical portion rotatably supported by the reel body, a pair of rotor arms disposed on opposite sides of the cylindrical portion and extending forward, and a fishing line guide portion swingably attached to a tip of the rotor arm. The spool further has a skirt portion integrally formed at a rear portion of the bobbin trunk so as to have a larger diameter than the bobbin trunk and to cover the cylindrical portion. Providing such a skirt makes it difficult for the fishing line to become entangled with the spool shaft.

A spinning reel according to a seventh aspect of the present invention is a spinning reel according to the first aspect.
In the reel according to any one of Items 1 to 6, a number of annular grooves are formed on the outer peripheral surface of the bobbin trunk at intervals in the axial direction. In this case, the frictional resistance to the fishing line at the start of winding is increased, and the fishing line is wrapped around the spool in an orderly manner.

The rotor 3 is, as shown in FIG.
0, and first and second rotor arms 31 and 32 provided on the side of the cylindrical portion 30 so as to face each other. The cylindrical portion 30 and the rotor arms 31, 32 are made of, for example, an aluminum alloy and are integrally formed. Cylindrical part 3

The bail arm 44 is swingable between a yarn guiding posture shown in FIG. 2 and a yarn releasing posture inverted from the yarn guiding posture.

A cover 45 is mounted on the outer peripheral side of the first bail support member 40, and inside the cover 45, the bail arm 44 is returned from the line releasing position to the line guiding position in conjunction with the rotation of the rotor 3. In addition, a bail reversing mechanism 46 for maintaining the state in both postures is arranged. Inside the cylindrical portion 30 of the rotor 3, a reverse rotation preventing mechanism 50 for prohibiting and releasing the reverse rotation of the rotor 3 is arranged. As shown in FIG. 1, the reverse rotation prevention mechanism 50 is a roller-type one-way clutch 51 in which the inner ring idles, and is a switch for switching the one-way clutch 51 between an operation state (reverse rotation prohibited state) and a non-operation state (reverse rotation permission state). And a mechanism 52.

As shown in FIG. 3, the spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3, and is mounted on the tip of the spool shaft 15 via a drag mechanism 60. Have been. The spool 4 has a bobbin trunk 4a around which the fishing line is wound, a skirt 4b integrally formed at the rear of the bobbin trunk 4a, and a flange plate 4c fixed to the front end of the bobbin trunk 4a. ing.

The bobbin trunk 4a is a cylindrical member obtained by forging an aluminum alloy, for example. The outer peripheral surface is a straight circumferential surface 4d parallel to the spool axis X.
A pair of tapered surfaces 4 whose diameter gradually decreases from both ends of the circumferential surface 4d
e and 4e. The circumferential surface 4d is formed at the center of the bobbin trunk 4a in the axial direction, and is formed of a pair of tapered surfaces 4e.
Are formed on both sides thereof with the same axial length. On the peripheral surface of the bobbin trunk 4a, for example, a large number of annular grooves 4f having a triangular cross section are formed at intervals in the axial direction. The bobbin trunk 4a is rotatably mounted on the spool shaft 15 by two bearings 56 and 57.

As shown in FIG. 4, a circumferential surface 4d of the bobbin trunk is provided.
Is at least 55%, preferably at least 60%, of the diameter D2 of the flange plate 4c. The diameter D1 is 45% to 120% of the axial length L of the entire bobbin trunk 4a. The axial length L1 of the circumferential surface 4d is in the range of 25% to 75% of the axial length L of the entire bobbin trunk 4a. In this case, since the length of the tapered surface is larger than that of the circumferential surface, the shape of the thread can be flattened even if the speed changes gently. Further, the minimum diameter D3 of the tapered surface 4e is in the range of 90% to 99% of the maximum diameter D1.

The skirt portion 4b is connected to the cylindrical portion 30 of the rotor 3.
Is forged integrally with the bobbin trunk 4a so as to cover the thread winding body 4a. The flange plate 4c is formed so as to be inclined forward toward the outer periphery and the inclination angle α is 7 degrees or less. The flange plate 4c is fixed to the bobbin trunk 4a by a spool ring collar 55 screwed to the inner peripheral surface of the bobbin trunk 4a.

By limiting the shape of the bobbin trunk 4a to the above numerical range, the diameter of the bobbin trunk 4a becomes relatively large with respect to the flange plate 4c, so that the fishing line is less likely to be curled. Further, even when the spool 4 is decelerated at the moving end when the fishing line is wound by the traversing cam type oscillating mechanism 6 on the bobbin trunk 4a having a substantially straight shape,
Since the tapered surfaces 4e are formed at both ends, the bobbin trunk 4
The shape of the bobbin is hardly changed at both ends of a, and the peripheral surface can be flattened.

At the time of casting, since the diameter of the bobbin trunk 4a is relatively large with respect to the flange plate 4c, the discharge resistance is small even if the bobbin trunk 4a has a straight shape parallel to the axis. In addition, since there is a release resistance rather than a taper, a backlash phenomenon in which the fishing line is released at a time can be prevented. Therefore, the fishing line can be wound regardless of the material of the fishing line.

The drag mechanism 60 is a mechanism mounted between the spool 4 and the spool shaft 15 for applying a drag force to the spool 4. The drag mechanism 60 has a knob 61 for manually adjusting the drag force, and a friction portion 62 composed of a plurality of disks pressed by the knob 61 toward the spool 4. [Reel Operation and Operation] At the time of casting, the bail arm 44 is reversed to the line releasing posture. This makes the first
The bail support member 40 and the second bale support member 42 swing. In this state, the fishing rod is cast while catching the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously by the weight of the device. When the handle 1 is rotated in the yarn winding direction after the device has landed,
The rotor driving mechanism 5 rotates the rotor 3 in the line winding direction, the bail arm 44 returns to the line winding position by the bail reversing mechanism 46, and the reverse rotation of the rotor 3 is prohibited. At the time of this casting, in the case of a fishing line of a nylon material, the bobbin trunk 4a of the spool 4
Is relatively large with respect to the flange plate 4c,
Even when the bobbin trunk 4a has a straight circumferential surface, the discharge resistance is reduced. Further, in the case of a fishing line made of a polyethylene material, the release resistance is larger than that of a tapered spool, so that backlash is less likely to occur. Moreover, if the front and rear positions of the spool 4 are adjusted by an appropriate position adjusting means such as a washer, the effect can be further enhanced. That is, if the position of the spool 4 is set to be later than usual, the thread winding shape becomes tapered, and the discharge resistance is further reduced. Conversely, if the distance is longer than before, the taper becomes thicker, the emission resistance increases, and backlash is less likely to occur.

When winding the fishing line, the handle 1 is rotated in the line winding direction. Then, the rotation is transmitted to the rotor 3 via the face gear 11 and the pinion gear 12, and the rotor 3 rotates. When the rotor 3 rotates, the fishing line guided by the line roller 41 is wound around the spool 4. At this time, since the bobbin trunk portion 4a of the spool 4 is substantially straight, the bobbin shape of the fishing line is less likely to collapse than the tapered bobbin trunk portion. Especially, spool 4
When the fishing line is tightly wound around the fishing line, the line winding shape is less likely to collapse, so that the fishing line is easily wound. Moreover, since the tapered surfaces 4e are formed at both ends, the spool shape can be flattened even if the spool 4 is decelerated at the moving end.

[Other Embodiments] (a) In the above embodiment, the tapered surfaces 4e of the same length are arranged on both sides of the circumferential surface 4d, but an oscillating mechanism in which the moving speed of the spool is different between forward and backward traveling is adopted. In such a case, the pair of tapered surfaces 4e may have different lengths. (B) In the above embodiment, the spool has a configuration in which the skirt covers the cylinder of the rotor. However, a spool in which the bobbin trunk covers the cylinder of the rotor like a spinning reel dedicated to throw fishing. The present invention can also be applied to

[0032]

According to the present invention, in consideration of the deceleration at the forward end and the backward end of the spool, the tapered surface is gradually reduced in diameter so that more fishing line is wound around both ends of the bobbin trunk than the circumferential surface. Is formed so that the outer peripheral side does not bulge in a bump-like manner even if a large amount of fishing line is wound around this portion. For this reason, even if the spool is moved back and forth by the traverse cam type oscillating mechanism, the winding shape of the spool can be flattened along the axis.
