Description

[Technical Field]

[0001] The present invention relates to a spool and a spinning reel. [Background technology]

[0002] Conventionally, the release of fishing line from the spool is controlled by providing an inclined surface on the outer periphery of the front flange of the spool, thereby preventing backlash caused by the line being released all at once. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4346632 [Patent Document 2] Patent No. 6783667 Summary of the Invention [Problem to be solved by the invention]

[0004] When reeling in a spinning reel, the fishing line can sometimes be wound loosely around the spool. If you cast while the fishing line is loosely wound around the spool, the loose line can go over the front flange and be released, which can also cause backlash (line tangles).

[0005] An object of the present invention is to provide a spinning reel spool that can suppress the occurrence of backlash. [Means for solving the problem]

[0006] A spool according to a first aspect of the present invention is a spool for a spinning reel, and includes a bobbin trunk and a front flange. The bobbin trunk extends in the axial direction. The front flange is located at the axial front end of the bobbin trunk. The front flange has a first wall portion, a first annular portion, and a second wall portion. The first wall portion is located on the outer periphery of the bobbin trunk and extends radially outward. The first annular portion is located forward of the outermost diameter portion of the first wall portion and extends forward. The second wall portion extends radially outward relative to the outer periphery of the first annular portion.

[0007] With this spool, the second wall portion prevents the fishing line wound loosely around the spool from climbing over the first annular portion and being released during casting, thereby providing a spinning reel spool that can prevent backlash.

[0008] The second wall portion of the spool according to the first aspect of the present invention extends flatly in a radial direction perpendicular to the axial direction relative to the outer peripheral surface of the first annular portion, and in this case, the second wall portion can further prevent the fishing line wound loosely around the spool from climbing over the first annular portion and being released during casting.

[0009] The second wall portion of the spool according to the third aspect of the present invention has a slope that slopes radially inward toward the front, which makes it possible to increase the axial dimension of the spool.

[0010] The first annular portion of the spool according to any one of the first to third aspects of the present invention has an outer circumferential surface that extends flat in the axial direction and has a diameter that is substantially the same as the diameter of the line wound around the bobbin trunk, which corresponds to the upper limit of the amount of line that can be wound around the bobbin trunk. In this case, the first annular portion can be used as a guide for the amount of line that can be wound around the bobbin trunk.

[0011] The spool of a fifth aspect according to any one of the first to fourth aspects of the present invention further comprises an annular spool ring including the second wall portion. In this case, the second wall portion can be formed by the spool ring.

[0012] A spool according to a sixth aspect of the present invention is a spinning reel spool, comprising: a bobbin trunk extending in the axial direction; a first wall extending radially outward from the bobbin trunk; a second wall disposed forward of the outermost diameter portion of the first wall; and a retaining portion that retains the fishing line of a lower layer that is exposed from the outermost layer of fishing line wound in layers around the bobbin trunk so that it does not go beyond the second wall. With this spool, the second wall can prevent the fishing line wound loosely around the spool from going over the second wall and being released during casting.

[0013] A spinning reel according to a seventh aspect of the present invention comprises a spool according to any one of the first to sixth aspects. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a spinning reel spool that can suppress the occurrence of backlash. [Brief explanation of the drawings]

[0016] A spinning reel according to an embodiment will now be described with reference to the drawings. Figure 1 is a side view of a spinning reel 1. As shown in Figure 1, the spinning reel 1 includes a reel body 2, a handle 4, a spool 6, a rotor 8, a bail arm 10, and a line roller 12.

[0017] In the following description, the direction in which the rotation axis X of the spool 6 extends is referred to as the axial direction, the direction perpendicular to the rotation axis X is referred to as the radial direction, and the direction around the rotation axis X is referred to as the circumferential direction. Within the radial direction, the direction approaching the rotation axis X is referred to as the radially inward direction, and the direction away from the rotation axis X is referred to as the radially outward direction. Additionally, the direction in which the fishing line is released during casting will be referred to as the forward direction, and the opposite direction will be referred to as the rearward direction. In this embodiment, the front-to-rear direction coincides with the axial direction.

[0018] As shown in Figure 1, the reel body 2 has an internal space. The internal space of the reel body 2 houses mechanisms such as a rotor drive mechanism that drives the rotor 8 and an oscillating mechanism that winds the fishing line evenly around the spool 6.

[0019] The handle 4 is rotatably supported by the reel body 2. The handle 4 is located on the left side of the reel body 2. However, the handle 4 may also be located on the right side of the handle body.

[0020] The spool 6 is connected to a spool shaft via a drag mechanism (not shown). The spool shaft extends in the front-to-rear direction and is supported by the reel body 2 so as to be movable in the front-to-rear direction.

[0021] Fishing line is wound around the outer periphery of the spool 6. The spool 6 moves back and forth integrally with the spool shaft in response to rotation of the handle 4. Details of the spool 6 will be described later.

[0022] The rotor 8 is a member for winding fishing line onto the spool 6. The rotor 8 rotates around the rotation axis X via a rotor drive mechanism as the handle 4 rotates. The rotor 8 has a first rotor arm 8a and a second rotor arm 8b. The first rotor arm 8a and the second rotor arm 8b are disposed radially outward from the spool 6. The second rotor arm 8b is disposed radially opposite the first rotor arm 8a.

[0023] The bail arm 10 is configured to be swingable relative to the rotor 8. The bail arm 10 is swingably attached to the tip of each of the first rotor arm 8a and the second rotor arm 8b.

[0024] The bail arm 10 has a first bail support member 10a, a second bail support member 10b, and a bail 10c. The first bail support member 10a is swingably attached to the tip of the first rotor arm 8a. The second bail support member 10b is swingably attached to the tip of the second rotor arm 8b. The bail 10c is fixed to the first bail support member 10a and the second bail support member 10b. The bail 10c extends in an arc between the first bail support member 10a and the second bail support member 10b.

[0025] The line roller 12 is disposed at the tip of the first bail support member 10a. The line roller 12 guides the fishing line onto the spool 6 in response to the rotation of the rotor 8.

[0026] 2, the spool 6 has a bobbin trunk 20, a front flange 22, a rear flange 24, a skirt 26, and a fixing member 28. The bobbin trunk 20 extends in the axial direction. Fishing line is wound around the outer circumferential surface of the bobbin trunk 20.

[0027] The front flange 22 is disposed at the front end of the bobbin trunk 20. The front flange 22 extends radially outward from the front end of the bobbin trunk 20.

[0028] As shown in FIG. 3, the front flange 22 has a first wall portion 30, a first annular portion 32, a second wall portion (an example of a retention portion), and a second annular portion .

[0029] The first wall 30 is disposed on the outer periphery of the bobbin trunk 20. The first wall 30 extends radially outward from the front end of the bobbin trunk 20. The first wall 30 has a tapered shape and is inclined so that the radially outer side is positioned further forward than the radially inner side. The first wall 30 is formed integrally with the bobbin trunk 20. The outermost diameter of the first wall 30 is a guide position for determining the amount of fishing line to be wound around the bobbin trunk 20. In other words, the outer diameter of the front end of the fishing line to be wound around the bobbin trunk 20 is approximately the same as the outer diameter of the outermost diameter of the first wall 30.

[0030] The first annular portion 32 is disposed forward of the outermost diameter portion of the first wall portion 30. The first annular portion 32 extends forward from the outermost diameter portion of the first wall portion 30. The first annular portion 32 is integrally formed with the first wall portion 30 and smoothly connected to the first wall portion 30. The first annular portion 32 has an outer peripheral surface 32a that extends flat in the axial direction. The first annular portion 32 has a diameter that is approximately the same as the diameter of the line wound around the bobbin trunk 20, which is determined based on the upper limit of the amount of line that can be wound around the bobbin trunk 20. The outer peripheral surface 32a of the first annular portion 32 is cylindrical and extends along the axial direction. In a cross-sectional view, the outer peripheral surface 32a of the first annular portion 32 extends parallel to the axial direction. The front corners of the outer peripheral surface 32a of the first annular portion 32 extend forward and radially inward. The outer peripheral surface 32a of the first annular portion 32 may be inclined radially inward or radially outward toward the front.

[0031] The second wall portion 34 is disposed in front of the first annular portion 32. The second wall portion 34 extends radially outward from the front end of the outer circumferential surface 32a of the first annular portion 32. The second wall portion 34 is sandwiched between the first annular portion 32 of the front flange 22 and the fixing member 28 in the axial direction.

[0032] As shown schematically in Figure 4, the second wall 34 prevents a lower layer 62 of fishing line 60 wound in layers around the bobbin trunk 20, exposed from the outermost layer 61, from passing beyond the first annular portion 32. More specifically, the first annular portion 32 and the second wall 34 prevent a slack portion 62a of the fishing line 60 wound around the bobbin trunk 20, exposed from the outermost layer 61, from passing beyond the first annular portion 32 during casting. The slack portion 62a is wound around the bobbin trunk 20 in a slack state. The left side in Figure 4 is the front, which is the direction in which the fishing line is released during casting.

[0033] The second wall portion 34 extends radially outward relative to the outer peripheral surface 32a of the first annular portion 32. The second wall portion 34 extends radially outward from the front end of the outer peripheral surface 32a of the first annular portion 32. The second wall portion 34 extends flatly in the radial direction relative to the outer peripheral surface 32a of the first annular portion 32. Note that the second wall portion 34 may be inclined so that the radially outer side is located further forward or rearward than the radially inner side.

[0034] The second annular portion 36 is disposed in front of the second wall portion 34. The second annular portion 36 extends forward from the outermost diameter portion of the second wall portion 34. The second annular portion 36 is integrally formed with the second wall portion 34. The second annular portion 36 has a first inclined portion 36a and a second inclined portion 36b. The first inclined portion 36a increases in diameter from the outermost diameter portion of the second wall portion 34 toward the front. The second inclined portion 36b is disposed in front of the first inclined portion 36a. The second inclined portion 36b decreases in diameter toward the front. The second inclined portion 36b is smoothly connected to the first inclined portion 36a. The axial dimension of the second inclined portion 36b is smaller than the axial dimension of the first inclined portion 36a.

[0035] In this embodiment, the second wall portion 34 and the second annular portion 36 are formed by a spool ring 6a that is disposed between the first annular portion 32 of the front flange 22 and the fixing member 28. Therefore, the second wall portion 34 is formed as a separate body from the first annular portion 32. However, the second wall portion 34 may also be formed integrally with the first annular portion 32.

[0036] The rear flange 24 is disposed at the rear end of the bobbin trunk 20. The rear flange 24 extends radially outward from the rear end of the bobbin trunk 20. The rear flange 24 is formed integrally with the bobbin trunk 20.

[0037] As shown in Fig. 5, the rear flange 24 has a wall portion 40. The wall portion 40 is disposed on the outer circumferential side of the bobbin trunk 20. The wall portion 40 extends radially outward from the rear end of the bobbin trunk 20. The wall portion 40 has a tapered shape and is inclined so that the radially outer side is located further rearward than the radially inner side.

[0038] The wall portion 40 has an indicator portion 40a and a flat portion 40b. The indicator portion 40a is an indicator of the amount of winding of the lower end of the fishing line wound around the bobbin trunk 20. The indicator portion 40a is an annular step formed on the wall portion 40. The indicator portion 40a has, for example, a groove shape. The indicator portion 40a has a shape that is concave from the front to the rear. The outer diameter of the indicator portion 40a (the distance from the rotation axis X to the indicator portion 40a) is approximately the same as the outer diameter of the first annular portion 32. The flat portion 40b extends annularly radially outward from the indicator portion 40a. The flat portion 40b extends flat in the radial direction.

[0039] 2, the skirt portion 26 extends rearward from the outermost diameter portion of the rear flange 24. The skirt portion 26 has a cylindrical shape. The skirt portion 26 is integrally formed with the rear flange 24.

[0040] The fixing member 28 is screwed to the inner circumferential surface of the bobbin trunk 20. A portion of the fixing member 28 is disposed in front of the front flange 22. An adjustment knob 50 for adjusting the drag force of the drag mechanism is disposed on the inner circumferential surface of the fixing member 28.

[0041] As shown in Figure 6, if S1 is a first region bounded by a first line L1 passing through points A1 and B1, a second line L2 passing through points A1 and C, and a third line L3 passing through point B1 and parallel to the axial direction, and S2 is a second region bounded by first line L1, the second wall portion 34, and the outer peripheral surface 32a of the first annular portion 32, then it is preferable that the relationship S2 / S1 ≥ X (X is a constant) be satisfied. Note that X is preferably a large value, such as 1. By making the second region S2 larger than the first region S1, it is expected that the second wall portion 34 will have a greater effect on retaining the slack portion 62a of the fishing line.

[0042] Point A1 is the outermost diameter of the first wall portion 30. Point B1 is the point that comes into contact with the spool ring 6a at the shortest distance when the fishing line is released from point A1, and in this embodiment, is the outermost diameter of the second wall portion 34. Point C is the intersection of a line (second line L2) that passes through point A1 and is parallel to the radial direction and a line (third line L3) that passes through point B1 and is parallel to the axial direction.

[0043] As shown in FIG. 7, if the distance from point A1 to point C is h and the diameter of the fishing line wound around the bobbin trunk 20 is φd, the second wall 34 can be expected to retain the slack portion 62a of the fishing line by satisfying the relationship Y≧h / d≧X (X and Y are constants). X is, for example, 1, and Y is, for example, 10. In FIG. 7, point A2 is approximately the position of the indicator 40a, and is the outermost diameter of the rear end of the fishing line when it is wound around the bobbin trunk 20. Point B2 is the point where the fishing line first comes into contact with the spool 6 when it is released from point A2 via the shortest path. Point B2 is the outermost diameter of the spool ring 6a, which in this embodiment is the outermost diameter of the second annular portion 36 (the outermost diameter of the first inclined portion 36a).

[0044] In the spinning reel 1 configured as described above, the second wall portion 34 prevents the slack portion 62a of the fishing line wound loosely around the spool 6 from climbing over the first annular portion 32 and being released during casting. This makes it possible to provide a spinning reel 1 and a spool 6 for the spinning reel 1 that are capable of preventing backlash. Note that, although this embodiment illustrates X as 1 and Y as 10, the values ​​of X and Y were verified using a PE line, which is a braided line, and may be different when using a monofilament line such as nylon, fluorocarbon, or polyester.

[0045] <Other embodiments> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0046] As shown in FIG. 8, the outer peripheral surface 32a of the first annular portion 32 may be inclined radially inward toward the front.

[0047] As shown in FIG. 9, the dimension D1 of the outer circumferential surface 32a of the first annular portion 32 in the axial direction may be larger than the dimension D2 from the second wall portion 34 to the point B2 in the axial direction.

[0048] 10, the second wall portion 34 may have an inclined surface 52 that slopes radially inward toward the front. The second wall portion 34 has a shape that covers a part of the outer circumferential surface 32a of the first annular portion 32. This expands the second region S2.

[0049] 11, the spool ring 6a may be inclined radially inward toward the front side of the second wall portion 34. The axial dimension of the second inclined portion 36b may be greater than the axial dimension of the first inclined portion 36a. [Explanation of symbols]
