DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a spool mounted on a fishing spinning reel.

[0002]

2. Description of the Related Art As is well known in the art, a spinning reel for fishing uses a semi-annular bail at the tip of a pair of support arms provided on a rotor to a fishing line winding position and a fishing line discharging position via a bail support member. Each is mounted so that it can be inverted. When the veil is moved down to the fishing line release position and the fishing rod is vigorously swung down and the device is thrown, the fishing line wound on the spool is released in a spiral shape, and the veil is reversed to the fishing line winding position, and the handle is operated. When the rotor is rotated in the fishing line winding direction, the fishing line is wound on a spool that traverses back and forth in conjunction with the rotation of the rotor.

As shown in Japanese Utility Model Laid-Open Publication No. 63-37869 or FIG. 7, a spool 1 conventionally mounted on a spinning reel of this type includes a front flange 3, a fishing line winding body 5, and a rear side. And a flange 7. Generally, the line winding surface 5a of the fishing line winding body 5 is formed in a tapered shape (positive taper) having a smaller diameter toward the front in the spool axial direction, and the fishing line is tapered along the line winding surface 5a. It is to be turned.

[0004]

However, in the conventional spool shape as described above, when the fishing rod is vigorously swung down and the fishing line is discharged far away, the fishing line is wound around the thread winding surface 5a near the rear side flange portion 7. Although the turned fishing line is smoothly fed out, there is a possibility that the fishing line near the front flange 3 may break forward due to the momentum at the time of release and the line resistance between the fishing lines.

Further, even when the fishing line is wound on the spool 1 which traverses in the front-rear direction by the rotation of the rotor, the fishing line winding body 5 in the vicinity of the front flange portion 3 is formed because the fishing line winding body 5 has a positive taper. It was a fact that the fishing line wound around the trunk portion 5 had some line breakage. It has been pointed out that when such a line break occurs in the fishing line, a smooth fishing line feeding operation cannot be performed, and the flight distance of the fishing line cannot be increased.

Japanese Utility Model Registration No. 3007531 discloses a spool in which a line winding surface 9a of a fishing line winding body 9 is formed into a tapered shape (reverse taper) in a direction opposite to the line winding surface 5a as shown in FIG. 11 are disclosed. According to the spool 11, since the line winding surface 9a has a reverse taper, the line winding surface 9a is not affected by the momentum at the time of release, and the line break of the fishing line 13 can be prevented.

However, the fishing line winding surface 9a of the fishing line winding body 9 is
By using a reverse taper, line breakage can be prevented, but since the line resistance between the fishing lines 13 at the time of releasing the fishing line becomes larger than that of the positive taper, there remains a problem that the flight distance of the fishing line 13 cannot be secured. I have.

The present invention has been devised in view of the above circumstances, and it is intended to prevent the line from breaking when the fishing line is released.
It is an object of the present invention to provide a spool of a fishing spinning reel in which a flight distance of a fishing line is improved.

[0009]

In order to achieve the above object, the invention according to claim 1 is to form a front flange and a rear flange on the front side and the rear side of a fishing line winding body, and to form the fishing line. In the spool of the fishing spinning reel in which the winding body is formed in a tapered shape in which the diameter gradually decreases toward the front in the spool axial direction, the front flange portion has a tapered shape in a direction opposite to the fishing line winding body. ,
Set the taper angle sequentially smaller from the front end of the front flange
A plurality of tapered portions are formed, and a fishing line can be wound around each of the tapered portions.

According to a second aspect of the present invention, there is provided a spinning reel spool for fishing wherein a front flange and a rear flange are formed on a front side and a rear side of a fishing line winding body. The body has a plurality of tapered portions that gradually decrease in diameter toward the front in the spool axial direction, and the tapered portion on the rear flange portion side is provided .
The taper angle is gradually reduced from the tapered portion toward the front flange portion side .

(Action) When fishing with a fishing spinning reel equipped with the spool according to each claim, as in the prior art, if the bale is tilted to the fishing line discharge position side and the device is thrown, the spool is wound around the spool. The fishing line is fed out in a spiral. In the spool according to the first aspect, since the front flange portion is formed in a reverse taper in a direction opposite to the fishing line winding body portion, the fishing line wound in such an area is affected by the force at the time of release. Line breakage does not occur, and the fishing line wound in such an area becomes a block, and the line breakage due to the line resistance and the like of the fishing line wound around the fishing line winding body near the front flange portion is actively performed. To prevent. Again
The taper angle is gradually reduced from the tapered part on the tip side of the side flange.
Between the fishing lines at the front flange when the fishing line is released.
Since the yarn resistance is reduced sequentially from the front end, the front flange
Has a large shadow on the flight distance of the fishing line
The fishing line has a good flight distance without affecting the sound.
Becomes

[0012] According to the invention of claim 2, fishing line
Since the taper angle of the tapered portion on the front flange portion side in the winding trunk portion is smaller than the tapered portion on the rear flange portion side, the line resistance between the fishing lines in the tapered portion on the front flange portion side is smaller than that of the conventional one. As a result, in the fishing line wound in such an area, the degree of occurrence of line breakage due to the momentum at the time of release of the line and line resistance is significantly reduced, and the line breakage during the winding operation is also reduced. Significantly reduced.

The fishing line wound around the tapered portion on the front flange portion forms a block, thereby actively preventing the fishing line wound on the fishing line winding trunk portion on the rear flange portion from breaking. Will be done.

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings.

[0015] Figure 1 shows a first embodiment of the invention according to claim 1, in FIG. 15 is a reel unit of a spinning reel 17, the rotor 19 to the front end of the reel body 15 is axially attached rotatably In addition, a pair of support arms 21 are formed integrally with the rotor 19 in the front-rear direction of the reel body 15. A bail support member (not shown) is mounted at the distal end of each support arm 21 so as to be reversible between a fishing line winding position and a fishing line discharge position, and a semi-annular bail is attached between the bail support members. I have.

The reel body 15 has the rotor 19
The spool 23 is mounted coaxially with the
Numeral 3 is screwed via a mounting nut 27 to the tip of a spool shaft 25 which is attached to the reel body 11 so as to be able to traverse. Further, a handle 29 for winding the fishing line is mounted on the reel body 15, and the rotating shaft of the handle 29 and the rotor 19 are connected to each other via a conventionally known gear mechanism 35 including a drive gear 31 and a pinion 33. The spool shaft 25 is moved by a well-known traverse mechanism 41 including a slider 37 and a traverse cam shaft 39 fixed to the rear end.
The reel unit 15 traverses in the front-rear direction in conjunction with the rotation of the rotor 19.

And like the conventional spinning reel,
When the bale is tilted to the fishing line release position and the device is thrown, the fishing line 43 wound around the spool 23 is fed out in a spiral shape, and the bale is inverted to the fishing line winding position and the rotor 19 is wound by the handle operation. When rotated in this direction, the fishing line 43 is wound around the spool 23 that traverses in the front-rear direction of the reel body 15 in conjunction with this.

Thus, the present embodiment is characterized in that the following improvement is applied to the spool 23 in the spinning reel 17 configured as described above. That is, as shown in FIGS. 1 and 2, the spool 23 according to the present embodiment is
A fishing line winding body 45 formed in a tapered shape (positive taper) in which a line winding surface 45a becomes gradually smaller in diameter in the axial direction forward of the spool shaft 25, and provided on the front side and the rear side of the fishing line winding body 45. The front flange portion 47 is formed by a front flange portion 47 and a rear flange portion 49, and the front flange portion 47 has a different taper angle in a direction (reverse taper) opposite to the taper shape of the fishing line winding body 45 (2). The first tapered portion 47a and the second tapered portion 47b.

The taper angle α of the first taper portion 47a located on the distal end side of the front flange portion 47 with respect to the spool shaft 25 is set to be larger than the taper angle β of the second taper portion 47b. Then, as shown in FIG.
However, the first and second tapered portions 47a,
It is wound around the spool 23 along the shape of 47b.

Since the spool 23 according to the present embodiment is constructed as described above, when fishing is performed with the spinning reel 17 to which the spool 23 is mounted, similarly to the related art,
If you throw the device by tilting the veil to the fishing line release position,
The fishing line 43 wound on the spool 23 is fed in a spiral shape. At this time, the rear flange 49
The fishing line 43 wound on the nearby line winding surface 45a is smoothly fed out.

Since the first taper portion 47a and the second taper portion 47b are formed in a reverse taper in a direction opposite to that of the fishing line winding body 45, the fishing line 43 wound in such a region is discharged. No line break occurs due to the influence of the momentum, and the fishing line 43 wound in such an area at the time of releasing the fishing line or winding the fishing line becomes a block, and the fishing line winding cylinder near the front side flange portion 47 is formed. The fishing line 43 wound around the portion 45 is actively prevented from breaking due to line resistance or the like.

Further, when the spool is formed in a reverse taper shape as already described with reference to FIG. 8, the line resistance between the fishing lines at the time of releasing the fishing line becomes larger than that of the positive taper, so that the flying distance of the fishing line does not increase. There are drawbacks. However, in the present embodiment, the first taper portion 47a and the second taper portion 47b having the reverse taper are formed in the front flange portion 47, but from the first taper portion 47a on the tip side of the front flange portion 47 to the second taper portion 47b. And the taper angle are sequentially set to be smaller to reduce the yarn resistance in the front flange portion 47 sequentially from the front end side.
Does not significantly affect the flight distance of the fishing line.

Therefore, if the spool 23 according to the present embodiment is used, the fishing line 43 during the release of the fishing line and the winding of the fishing line can be used.
It is possible to improve the flight distance of the fishing line 43 while preventing line breakage. Figure 3 shows a second embodiment of the spool according to claim 1. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the figure, reference numeral 51 denotes a spool.
Similarly to the spool 23, 1 is a fishing line winding body 53 formed in a tapered shape (positive taper) in which a line winding surface 53a gradually becomes smaller in diameter in the axial direction forward of the spool shaft 25; 53 includes a front flange portion 55 and a rear flange portion 57 provided on the front side and the rear side, respectively. The front flange portion 55 is composed of two first taper portions 55a and second taper portions 55b having different taper angles in the opposite direction (reverse taper) to the taper shape of the fishing line winding body 53,
The taper angle of the first taper portion 55a located on the front end side of the front flange portion 55 with respect to the spool shaft 25 is the second taper portion 55a.
It is set larger than the taper angle of b. And
The fishing line 43 is moved from the fishing line winding body 53 to the first and second taper portions 5.
It is configured to be wound around the spool 51 along the shapes of 5a and 55b.
A flat portion 53b parallel to the spool shaft 25 is provided on the front side of the fishing line winding body 53.

Thus, even if the spool 51 according to the present embodiment is used, the first tapered portion 55a provided on the front flange 55
And the second taper portion 55b are formed in a reverse taper in a direction opposite to that of the fishing line winding body 53, so that the fishing line 43 wound in such a region is broken by the force at the time of releasing the fishing line. Also, even in the flat portion 53b, the degree of occurrence of line breakage is smaller than when the fishing line 43 is wound around the liner surface 53a having a positive taper.

The fishing line 4 wound around these areas
The block 3 serves to positively prevent the line breakage due to the line resistance and the like of the fishing line 43 wound around the liner surface 53a having the positive taper. Further, in the present embodiment, the taper angle is gradually set to be gradually smaller from the first taper portion 55a to the second taper portion 55b and the flat portion 53b, and the yarn resistance in the front flange portion 55 is sequentially reduced from the front end side. Because it is reduced, the front flange 5
By making 5 a reverse taper, the flight distance of the fishing line 43 is not significantly affected.

Therefore, even if the spool 51 according to the present embodiment is used, it is possible to improve the flight distance of the fishing line 43 while preventing the line from breaking when the fishing line is released.
In each of the above embodiments, two reverse taper portions having different taper angles are provided on the front flange portion, but the number of such taper portions is not limited to two. Figure 4 shows a first embodiment of a spool according to claim 2. In this embodiment, the same components as those in the embodiment shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

[0028] At a 4, 59 in the spool, the spool 59 includes a fishline winding barrel portion 61 which is formed into successively smaller diameter tapered (positive taper) toward the axially forward of the spool shaft 25 The fishing line winding body 61 includes two first taper portions (first thread winding surfaces) 61a having different taper angles and a second taper portion. (Second thread winding surface) 61b.

The first tapered portion 61a located on the front flange 63 side is formed in the axial direction of the spool shaft 25 to have a size of about １ ／ of the second tapered portion 61b. The angle γ is set smaller than the taper angle δ of the second taper portion 61b, and the taper angle γ is a gentler angle than the fishing line winding body 5 of the conventional spool 1 shown in FIG. .

Since the spool 59 according to the present embodiment is constructed as described above, when fishing with a spinning reel equipped with the spool 59, the bale is tilted to the fishing line discharge position side and the device is thrown. The fishing line 43 wound around the fishing line winding body 61 of 59 is fed out in a spiral shape, but the fishing line winding body 61 is formed into a positive taper, and occupies the main part of the fishing line winding body 61 again. Since the taper angle δ of the second taper portion 61b is set to be larger than the taper angle γ of the first taper portion 61a, the fishing line 43 is smoothly fed.

As described above, the first tapered portion 61a on the front flange 63 side is set at a gentler angle than the second tapered portion 61b and the fishing line winding body 5 of the spool 1 in FIG. From the fishing line 4 in the first tapered portion 61a.
3. The mutual line resistance is reduced as compared with the conventional art. As a result, in the fishing line 43 wound in such a region, the degree of occurrence of line breakage due to the momentum at the time of releasing the line and the line resistance is significantly reduced, and Thread breakage during the winding operation is also significantly reduced. And
The fishing line 43 wound around the first tapered portion 61a forms a block, and the fishing line 43 wound around the second tapered portion 61b.
The yarn breakage due to the yarn resistance or the like is positively prevented.

Therefore, the spool 59 according to the present embodiment can also improve the flight distance of the fishing line 43 while preventing the line from breaking during the release of the fishing line or the winding of the fishing line. FIG. 5 shows a second embodiment of the spool according to claim 2 , in which 67 is a spool, and the spool 67 according to this embodiment is also a fishing line winding body 69 and a front flange provided before and after it. 71 and a rear flange 73.

The fishing line winding body 69 has two first taper portions (first thread surface) 69a and a second taper portion (first taper surface) 69, each of which has a diameter gradually decreasing toward the front in the axial direction of the spool shaft 25. A first tapered portion 69a located on the side of the front flange portion 71 is approximately one-fourth the size of the second tapered portion 69b. And the spool shaft 2
5, the taper angle ε of the first taper portion 69a is set smaller than the taper angle θ of the second taper portion 69b located on the rear flange portion 73 side.
Also, the angle is set to be gentler than that of the fishing line winding body 5 of the conventional spool 1 shown in FIG. 7, but in the present embodiment, in addition to such a structure, the spool shaft 25
And a flat portion 69c parallel to the flat portion 6 is provided.
9c and the first and second tapered portions 69a and 69b form a fishing line winding body 69.

As described above, the spool 6 according to this embodiment is
7, the first and second tapered portions 69a and 69b are formed into a positive taper, and the taper angle θ of the second tapered portion 69b occupying the main portion of the fishing line winding body 69 is also the first tapered portion 69a.
It is set to be larger than
3 will be fed out smoothly.

Then, the first tapered portion 6 on the front flange 71 side.
9a is the second taper portion 69b or the conventional spool 1 shown in FIG.
Since the taper angle is set to be gentler than that of the fishing line winding trunk portion 5, the line resistance between the fishing lines 43 at the first taper portion 69a is reduced as compared with the conventional case, and as a result, the winding is performed in such a region. In the fishing line 43, the degree of line breakage due to the momentum and line resistance at the time of release of the line is significantly reduced, and the line breakage during the winding operation is also significantly reduced. In the flat portion 69c, since the degree of line breakage is smaller than that in the first taper portion 69a, the fishing line 43 wound around these regions becomes a block, and the second taper portion 69a
The line breakage due to the line resistance and the like of the fishing line 43 wound around b is positively prevented.

Therefore, according to the spool 67 according to the present embodiment, the flying distance of the fishing line 43 is improved while the line breakage at the time of releasing the fishing line and winding the fishing line is more reliably prevented as compared with the spool 59. It is possible to achieve. 6 Claim 2

a and 75b constitute the fishing line winding body 75 of the spool 77, and these are connected in a round shape, and the front flange 79 is formed separately from the fishing line winding body 77. is there.

The front flange 79 is formed by oil-impregnable powder metallurgy (for example, aluminum, copper, stainless steel, etc.) having a minute internal cavity into substantially the same shape as that of the front flange 63. It has a structure fixed to the tip of the fishing line winding body portion 77. In addition, in the drawing, reference numeral 83 denotes a rear flange. Thus, also in the present embodiment, it is possible to improve the flight distance of the fishing line 43 while preventing the line from breaking during the release of the fishing line or the winding of the fishing line, as in the above-described embodiments. However, as described above, in the present embodiment, since the front flange 79 is formed by powder metallurgy capable of impregnating oil, frictional resistance is reduced by an oil impregnation effect, and it is possible to reduce sound emission during fishing line releasing operation. .
