Abstract

PROBLEM TO BE SOLVED: To prevent a backlashing outward from a flange part in the spool of a spinning reel. SOLUTION: The cross section vertical to the spool axis 15 of the front end part 7c of a spool body is circular and the cross-section vertical to the spool axis 7c of a flange unit 8 is oval including the circular portion of the front end part 7c. The distance A along the major axis of the oval part from the periphery of the spool body to the periphery of the flange unit 8 is different from the distance B along the minor axis of the oval part from the periphery of the spool body to the periphery of the flange unit 8 (the minimum position) in the difference between the major axis and the minor axis. In this case, a fishline can be wound to the minimum position of the flange unit 8 and the part of difference in distance between A-B of the flange unit 8 is brought to be unable to be wound with the fishline. Thus, the part of the distance difference A-B causes a wall to hardly occur a backlashing outward from the flange unit.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool,
The present invention relates to a spinning reel spool that can move back and forth with respect to a reel body.

[0002]

2. Description of the Related Art A spinning reel generally includes a reel body rotatably supporting a handle, a rotor, and a spool. This spool is movable back and forth with respect to the reel body, and has a cylindrical bobbin trunk around which a fishing line is wound, a flange portion disposed at the front end of the bobbin trunk and having a larger diameter than the bobbin trunk, and a spool bobbin. And a skirt portion integrally formed at the rear. The flange portion is fixed to the bobbin trunk by a flange fixing member.

[0003] In this type of spool, the bobbin trunk is mounted directly or via a drag mechanism on a spool shaft rotatably supported on a reel body, and the cross section perpendicular to the spool shaft of the bobbin trunk is circular. Is formed. The section of the flange section perpendicular to the spool axis is a concentric circle having a larger diameter than the section perpendicular to the spool axis of the bobbin trunk.

[0004]

In such a conventional spool, when a fishing line is wound around the bobbin trunk, the angler winds the fishing line around the outer diameter of the flange portion. Then, wrap the fishing line while paying attention so that the outer circumference of the fishing line wound around the bobbin trunk does not exceed the outer diameter of the flange, and finish the winding work before the outer diameter of the fishing line becomes equal to the outer diameter of the flange. I do.

However, in such a conventional winding operation of the fishing line around the spool, the fishing line may be wound up to the outer peripheral end of the flange portion. When the fishing line is wound to the outer peripheral end in this way, the so-called “backlash” that the wound fishing line spills off from the flange portion easily occurs. An object of the present invention is to prevent backlash from a flange portion outward in a spool of a spinning reel.

[0006]

A spool of a spinning reel according to a first aspect of the present invention is a spool of a spinning reel that is movable back and forth with respect to a reel body together with a spool shaft. A cylindrical bobbin body to be cut, and a flange portion disposed at a front end of the bobbin trunk portion and having an outer peripheral portion projecting outward from the outer peripheral portion of the bobbin trunk portion over the entire periphery. Has a portion where the height of the flange portion from the bobbin trunk is different from the other portions.

When the fishing line is wound around the bobbin trunk in such a spool, the diameter of the outer peripheral portion of the fishing line and the outer diameter of the flange portion become the same at the portion where the height of the flange portion is the lowest (minimum position). Become. In this state, a sufficient distance difference is left between the higher portion (maximum position) of the other portion of the flange portion and the outer periphery of the fishing line. Therefore, when performing the winding operation of the fishing line, the fishing line may be wound around the minimum position of the flange portion as a guide, and the operation may be completed when the height becomes the same as the height of the outer peripheral portion of the fishing line.

[0008] Here, the fishing line can be wound around the bobbin trunk in a state where backlash from the flange portion to the outside hardly occurs. A spinning reel spool according to a second aspect of the present invention is the spinning reel spool according to the first aspect, wherein at least one of the bobbin trunk portion and the flange portion has a non-circular cross section substantially perpendicular to the spool shaft. ing.

In this case, the bobbin trunk and the flange portion can be formed in any shape as compared with the conventional bobbin trunk and the flange portion having a circular cross section perpendicular to the spool shaft. Thus, a difference in height between the bobbin trunk portion and the flange portion is likely to occur. A spinning reel spool according to a third aspect of the present invention is the spinning reel spool according to the first or second aspect, wherein at least one of the bobbin trunk portion and the flange portion has an elliptical cross section substantially perpendicular to the spool axis. Is formed.

In this case, for example, when the cross section perpendicular to one of the spool shafts is circular, the cross section perpendicular to the other spool shaft is an ellipse having a short axis or a long axis equal to the diameter of the circle. Thereby, a difference in height between the bobbin trunk portion and the flange portion is likely to occur. A spinning reel spool according to a fourth aspect of the present invention is the spinning reel spool according to the third aspect, wherein both the bobbin trunk portion and the flange portion are
The shape of the cross section substantially perpendicular to the spool axis is elliptical,
In addition, they are formed such that their long axes are orthogonal to each other.

In this case, since the height of the bobbin trunk and the flange is formed so as to gradually change, the bobbin trunk and the flange can be smoothly and continuously formed in an outer shape and arranged in a well-balanced manner. it can. A spool of a spinning reel according to a fifth aspect of the present invention is the spool of the spinning reel of the first aspect, wherein both the bobbin trunk portion and the flange portion are circular in cross section substantially perpendicular to the spool shaft, and are mutually centered. Are formed to be eccentric.

In this case, by shifting the center between the bobbin trunk and the flange, a difference in height between the bobbin trunk and the flange tends to occur. The spinning reel spool according to a sixth aspect of the present invention is the spinning reel spool according to the fifth aspect, wherein the bobbin trunk portion and the flange portion are relatively movable such that their center positions coincide with each other and the height of the flange portion is constant. is there.

In this case, for example, the fishing line can be moved to a concentric position when the fishing line is released, and can be decentered when the fishing line is wound.

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. The spool 4 includes a spool body 7 having a cylindrical bobbin trunk 7a around which a fishing line is wound and a large-diameter cylindrical skirt portion 7b integrally formed at the rear of the bobbin trunk 7a, and a spool bobbin 7a. And a flange fixing member 9 for fixing the flange portion 8 to the spool body 7.

The spool body 7 is a cylindrical member having two stages, large and small, obtained by forging an aluminum alloy, for example, and is rotatably mounted on the spool shaft 15 by two bearings 56 and 57. The bobbin trunk 7 a is

The circumferential surface 16a is formed at the center of the cylindrical portion 16 in the axial direction,
The pair of tapered surfaces 16b are formed on both sides thereof with the same axial length. On the peripheral surface of the cylindrical portion 16, for example, a large number of annular grooves 16e having a triangular cross section are formed at intervals in the axial direction. A female screw portion 16 d for mounting the flange fixing member 9 is formed on the inner peripheral surface of the cylindrical portion 16. Bearings 56 are provided on the inner peripheral portions of the boss portions 18a and 18b.
57 are mounted. The protrusion 16 c is provided to sandwich the flange 8 with the flange fixing member 9.

The skirt portion 7b is connected to the cylindrical portion 30 of the rotor 3.
Is forged integrally with the bobbin trunk 7a so as to cover the body. The flange portion 8 is a scratch-resistant plate member made of metal or hard ceramic that is formed so as to be inclined forward toward the outer periphery and the inclination angle is 7 degrees or less. The outer diameter of the flange portion 8 is formed to be substantially the same as that of the skirt portion 7b. The flange portion 8 is sandwiched and fixed between the bobbin trunk 7a by a flange fixing member 9 screwed into the female screw portion 16d on the inner peripheral surface of the bobbin trunk 7a.

As shown in FIG. 4, the cross section of the front end 7c of the bobbin trunk 7a perpendicular to the spool shaft 15 is circular, and the cross section of the flange 8 perpendicular to the spool shaft 15 is the circular section of the front end 7c. It is an elliptical shape that encompasses. The distance A from the outer peripheral portion of the bobbin trunk 7a to the outer peripheral portion (maximum position) of the flange 8 along the major axis of the elliptical portion is from the outer peripheral portion of the bobbin trunk 7a along the minor axis of the elliptical portion. The distance B to the outer peripheral portion (minimum position) of the flange portion 8 is different from that of the elliptical portion by the difference between the major and minor axes.

When the fishing line is wound around the bobbin trunk 7a in such a spool 4, the fishing line is
(The distance B from the outer peripheral portion of the bobbin trunk 7a), and the fishing line can be prevented from being wound around the portion of the flange portion 8 at the distance AB. Therefore, the portion of the distance difference AB of the flange portion 8 becomes a wall, and backlash from the flange portion 8 to the outside is less likely to occur.

The flange fixing member 9 has a cylindrical screw portion 9a screwed into a female screw portion 16d formed on the inner peripheral surface of the spool body, and a drag formed integrally on the inner peripheral side of the screw portion 9a. A cylindrical drag storage portion 9b having a space in which a drag plate (described later) 62a to 62e of the mechanism 60 can be stored, and a contact portion provided at the tip of the screw portion 9a so as to be able to contact the flange portion 8; 9c.

On the outer peripheral surface of the screw portion 9a, a male screw portion 9 screwed to a female screw portion 16d formed on the inner peripheral surface of the cylindrical portion 16 is provided.
d is formed. The drag storage portion 9b is provided with a screw portion 9a.
Is arranged concentrically with the threaded portion 9a on the inner peripheral side of the threaded portion 9a, and its rear end extends to a position close to the disk portion 17. An annular spring mounting groove 9e for mounting, for example, a pentagonally bent spring member 65 for retaining the drag plates 62a to 62e is formed on the inner peripheral surface of the drag storage portion 9b. At the rear of the spring mounting groove 9e, a pair of locking grooves 9f, 9f for locking the drag plate 62c in a non-rotatable manner is formed along the axial direction. The contact portion 9c is a substantially disk-shaped member for connecting the screw portion 9a and the drag storage portion 9b and fixing the flange portion 8. The outer peripheral side portion of the contact portion 9c has a tapered conical shape, and its rear end surface is in contact with the flange portion 8.

The drag mechanism 60 is mounted between the spool 4 and the spool shaft 15 to apply 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 including a plurality of drag plates 62a to 62e pressed toward the spool 4 by the knob 61. Knob part 6
1 has a sound generating mechanism 61a and a nut 61b screwed to the spool shaft 15 therein. The drag plate 62 a is a metal disk member that is non-rotatably locked to the spool shaft 15 and contacts the knob 61. Drag plate 62b, 62
d is a disk member made of felt, for example. The drag plate 62c is a metal disk member having locking protrusions locked on the locking grooves 9f on the outer peripheral portion, and rotates together with the flange fixing member 9. The drag plate 62e is a metal disk member that is non-rotatably locked to the spool shaft 15, and has a sound generating mechanism 64 mounted at its rear end. The sound emitting mechanism 64 emits sound when the drag operates and the spool shaft 15 and the spool 4 rotate relative to each other.

Next, the operation and operation of the reel will be described. At the time of casting, the bail arm 44 is inverted to the line releasing posture. Thereby, the first bail support member 40 and the second bale support member 42 swing. In this state, the fishing rod is cast while hooking 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 3 is rotated in the yarn winding direction by the rotor drive mechanism 5, and the bail arm 44 is returned to the yarn winding position by the bail reversing mechanism (not shown). Since the reverse rotation of the rotor 3 is prohibited, the release of the fishing line stops.

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. Here, when the fishing line is wound on the spool 4 for the first time, the fishing line is wound only to the minimum position. Therefore, even if the fishing line is wound to the end at this time, backlash hardly occurs.
