Summary of the Invention

Problems to be Solved by the Invention

[0004] After fishing, the spinning reel for fishing may be washed. For example, water is discharged from a faucet to wash it. At this time, since the reel is washed from various directions such as up, down, left, and right, water may enter between the rotor and the body, and this entered water may further enter the body (that is, the one-way clutch). Furthermore, when dust and sand enter, it is difficult to discharge them even after washing, thus impairing the performance of the reel.

[0005] An object of the present invention is to provide a spinning reel for fishing with improved water resistance and reel performance.

Means for Solving the Problems

[0006] The spinning reel for fishing according to the present invention comprises a first cylindrical portion provided on the reel body and housing a one-way clutch inside, a second cylindrical portion having a front wall that rotates in conjunction with the rotation of the handle, a rotor having a pair of support arms facing each other on both sides of the second cylindrical portion and projecting forward, and a spool that moves back and forth when the rotor rotates and around which the fishing line is wound, wherein the second cylindrical portion overlaps with the first cylindrical portion in at least a portion, and a front wall through hole is formed in the front wall of the second cylindrical portion that opens between it and the outer circumferential surface of the first cylindrical portion.

[0007] In the spinning reel for fishing with the above configuration, the front wall of the second cylindrical part that constitutes the rotor has a through-hole in the front wall that opens between it and the first cylindrical part provided in the reel body. Therefore, even if water enters between the rotor and the body when the reel is washed from various directions (up, down, left, and right), the water can easily drain out through the through-hole in the front wall of the rotor, preventing water from accumulating inside. In this way, the water permeability is improved, making it more difficult for water to enter the one-way clutch housed inside the first cylindrical part, thus improving water resistance. Furthermore, even if sand and dust enter, they can be easily washed out and removed without impairing the performance of the reel. [Effects of the Invention]

[0008] According to the present invention, a spinning reel for fishing can be obtained with improved water resistance and reel performance. [Brief explanation of the drawing]

[0010] Hereinafter, embodiments of the spinning reel for fishing according to the present invention will be specifically described with reference to the drawings. Figures 1 to 6 show one embodiment of a spinning reel for fishing according to the present invention. In the following description, the front (front, front side) and rear (rear, rear side) of the spinning reel for fishing refer to the directions shown in the figures, with the front being the spool side and the rear being the reel body side. Furthermore, the radial direction refers to the diameter direction when the spool axis is viewed from the axial direction.

[0011] The reel body 2 of the spinning reel 1 for fishing has a leg portion 2A formed thereon that is attached to a fishing rod. Inside the reel body 2, a handle shaft 3A is rotatably supported via a bearing, and a handle 3 for winding is attached to the end of the handle shaft 3A. A known drive force transmission mechanism 30 is connected to the handle shaft 3A, which rotates the rotor 10 in accordance with the rotation operation of the handle 3 and moves the spool 5 back and forth via a known oscillating mechanism.

[0012] The spool 5 is formed of, for example, a light metal such as aluminum, an aluminum alloy, or a magnesium alloy, or a synthetic resin material, and has a fishing line winding cylinder portion 5a around which a fishing line is wound, and a front flange portion 5b and a rear flange portion (skirt portion) 5c that define the amount of winding of the fishing line winding cylinder portion 5a in the front-rear direction.

[0013] A pair of support arms 11 and 12 are formed on the rotor 10 so as to extend forward in the axial direction and face each other at an interval of approximately 180°. The spool 5 is positioned between the pair of support arms and is reciprocally driven back and forth. At the tip portions of the respective support arms 11 and 12, bail support members 14 and 15 are supported rotatably between a fishing line winding position and a fishing line releasing position via rotation support portions 14a and 15a. Further, a base end portion of a semi-annular bail 17 is attached to each of the bail support members 14 and 15, and the bail 17 is rotatable together with the bail support members 14 and 15. And a known fishing line guiding device 50 for guiding the fishing line to the spool 5 is provided at the tip of one of the bail support members (bail support member 15).

[0014] Incidentally, as will be described later, the rotor 10 includes a second cylindrical portion (cylindrical portion) 20, and the pair of support arms 11 and 12 are formed so as to project forward via connection portions 23A and 23B that project radially outward from the rear portion of the second cylindrical portion 20. An arc-shaped bridge 25 that projects radially outward from the outer peripheral surface of the second cylindrical portion 20 is formed at the rear portion of the rotor 10 and the first cylindrical portion 18 provided on the reel body 2 is disposed inside the arc-shaped bridge 25 and the second cylindrical portion 20. That is, the first cylindrical portion 18 and the second cylindrical portion 20 are disposed in a state of overlapping in the axial direction with a gap.

[0015] The first cylindrical portion 18 and the second cylindrical portion 20 may be in a state where all of their respective cylindrical walls overlap in the axial direction, or may be in a state where at least a part thereof overlaps. In the configuration shown in FIG. 3, the first cylindrical portion 18 shows a state where the outer side in the radial direction is entirely covered by the second cylindrical portion 20. However, for example, the second cylindrical portion 20 may be configured not to cover the rear end side of the first cylindrical portion 18. Further, the first cylindrical portion 18 may be integrally formed with the reel body 2, or may be formed separately from the reel body 2 and have a structure that is integrated.

[0016] Inside the first cylindrical portion 18, the constituent members constituting the driving force transmission mechanism 30 are accommodated. The constituent members to be accommodated rotatably insert a spool shaft 5A that rotatably supports the spool 5, and include a part of a pinion gear 31 that meshes with the face gear 3B and a known one-way clutch 32 disposed on the outer peripheral surface side of the pinion gear 31. This one-way clutch 32 has a function (reverse rotation prevention function) of allowing rotation in the fishing line winding direction of the rotor 10 and restricting rotation in the reverse direction, and by operating a switching lever (not shown), it is configured to allow rotation of the rotor 10 in the reverse direction.

[0017] FIGS. 1 and 2 show a fishing line winding state. When the handle 3 is rotationally operated in this state, the rotor 10 is rotationally driven via the driving force transmission mechanism, and the spool 5 is reciprocally driven back and forth via the oscillating mechanism. As a result, the fishing line is evenly wound around the fishing line winding drum portion 5a of the spool 5 via the fishing line guiding device 50 of the bail support member 15 that rotates with the rotor 10.

[0018] When the bail 17 is rotated (rotated in the direction of the arrow) to the fishing line release position along with the rotation of the bail support members 14 and 15 from the fishing line winding state shown in the figure, the fishing line wound around the spool 5 becomes in a releasable state (not shown). Then, after releasing the fishing line in this fishing line release state and rotating the bail 17 from the fishing line release position to the fishing line winding position, the fishing line is picked up by the bail 17 and guided to the fishing line guiding device 50, and becomes the fishing line winding state shown in FIGS. 1 and 2.

[0019] Next, the configuration of the rotor 10 will be described. The rotor 10 is integrally formed from a lightweight and high-strength material, such as an aluminum alloy, magnesium alloy, or hard resin. The pair of support arms 11 and 12 are integrally formed on the rotor 10, projecting forward along the spool shaft 5A at approximately 180° intervals, and the second cylindrical portion 20 is formed between the pair of support arms 11 and 12. As shown in Figure 3, this second cylindrical portion 20 is integrally formed with the rotor 10.

[0020] The cylindrical wall 21 constituting the second cylindrical portion 20 is partially closed at the front by the front wall 22, and its rear end is open in a substantially circular shape. In this case, the rear end of the cylindrical wall 21 is integrated with the arc-shaped bridge 25, and the rear end of the arc-shaped bridge 25 is open in a substantially circular shape. Furthermore, the cylindrical wall 21 has a cylindrical wall opening (drainage opening) 21a formed therein to reduce weight. In this embodiment, the cylindrical wall opening 21a opens in an arc shape along the circumferential direction from the upper side of the cylindrical wall 21 to the rear end, and the area other than the part facing the pair of support arms 11, 12 (the pair of arc-shaped walls 21e) has a cylindrical wall opening 21a of substantially the same shape. The lower ends of each arc-shaped wall 21e are connected to the lower ends of the support arms 11, 12 via the connecting parts 23A, 23B, and the surface of each arc-shaped wall 21e faces the support arms 11, 12 at a constant distance.

[0021] In this way, the cylindrical wall opening 21a is formed to be large by removing the rear end edge of the cylindrical wall 21, so that this portion becomes a through hole, and an arc-shaped bridge 25 is disposed in this portion so as to project radially in substantially the same plane as the rear end edge of the cylindrical wall 21. The arc-shaped bridge 25 is integrally formed with the cylindrical wall 21 and a pair of support arms 11 and 12, and is formed in an annular (approximately ring-shaped) manner radially outward from the cylindrical wall opening 21a, forming the rear part of the second cylindrical portion 20 of the rotor 10 (the rear end of the cylindrical wall 21), and also connecting the respective sides of the bases of the support arms 11 and 12.

[0022] Therefore, the cylindrical wall opening 21a is positioned radially inward of the arc-shaped bridge 25, extending from the rear end edge of the cylindrical wall 21 toward the arc-shaped bridge 25. In this embodiment, the cylindrical wall opening 21a is formed opposite to each of the positions where the pair of support arms 11 and 12 are formed at approximately 90° angles, and is integrated with the arc-shaped bridge 25. As a result, the cylindrical wall opening 21a becomes a large opening area (water-permeable hole) extending from the second cylindrical portion 20 to the arc-shaped bridge 25, ensuring water permeability even when the reel is washed with water while turned sideways, thereby improving water resistance and reel performance. Furthermore, since the cylindrical wall opening 21a is formed on both sides of the arc-shaped wall 21e opposite the pair of support arms 11 and 12, the rotor 10 can be made lighter while efficiently maintaining its strength.

[0023] Furthermore, the cylindrical wall opening may be formed above the position where the pair of support arms 11 and 12 are formed (the position of the connection portion 23A and 23B). In addition, it is preferable that the arc-shaped bridge 25 is integrally formed from the same material as the support arms 11 and 12.

[0024] The front wall 22 of the cylindrical wall 21 of the second cylindrical portion 20 is provided with a flat bridge 22A that is radially bridged across the front end opening of the cylindrical wall 21 by a predetermined width. In this case, both sides of the bridge 22A may be formed to have a wide space extending to the arc-shaped bridge 25 by the opening in the cylindrical wall 21a, but in this embodiment, both sides of the upper end of the arc-shaped wall 21e are connected by semi-annular frames 21c and 21d. That is, the bridge 22A is bridged across the cylindrical wall 21 of the second cylindrical portion 20 between the two support arms 11 and 12, and both sides of it are equipped with the semi-annular frames 21c and 21d to form a space.

[0025] In this case, the rotor can be made lighter by making the cylindrical wall opening 21a larger, but if it is made too wide in the circumferential direction, the strength will decrease. In particular, since a large load acts on the position where the support arms 11 and 12 are formed, it is preferable not to form an opening in at least a certain range of arc region facing the support arms 11 and 12. Furthermore, the semi-annular frames 21c and 21d may be formed along the upper edge of the cylindrical wall 21 (arc wall 21e), but in this embodiment they are formed below the upper edge of the cylindrical wall 21, thereby effectively preventing deformation of the arc wall 21e and stabilizing the cap member by engaging it with the cap member described below.

[0026] The front wall 22 of the cylindrical wall 21 of the second cylindrical portion 20 is equipped with a cap member (a cap-shaped cover member) 22B attached to the surface of the bridge 22A and integrally formed from synthetic resin or the like. Therefore, the front wall 22 of the cylindrical wall 21 of the second cylindrical portion 20 is composed of the bridge 22A and the cap member 22B. The front wall 22 may also be integrally formed with the rotor 10 (second cylindrical portion 20).

[0027] The bridge 22A has an opening 22a through which the spool shaft is inserted and for mounting a nut 36 that rotatably secures the pinion gear 31, which is a component of the drive force transmission mechanism. Also, the boss 22k of the cap member 22B is fitted into Four holes 20b are formed in positions corresponding to the boss (there may be any number of holes, and their positions are not limited).

[0028] The cap member 22B comprises a circumferential wall 22c, an annular flange portion (locking portion) 22d that protrudes radially outward from the upper opening edge of the circumferential wall to suppress thread slippage, and a top plate 22f having an insertion hole 22e formed in the central region through which the spool shaft 5A is inserted. The circumferential wall 22c is provided with a pair of arc-shaped walls 22g that hang down in an arc shape at two opposing locations, and the back surface of the top plate 22f is attached in contact with the bridge 22A. The cap member 22B is attached to the bridge 22A by, for example, fitting the bosses 22k that are formed to protrude at four locations into the holes 20b and then bonding, welding, or the like.

[0029] The top plate 22f of the cap member 22B has a front wall through-hole 22h that opens between it and the outer circumferential surface of the first cylindrical portion 18 provided on the reel body 2. This front wall through-hole 22h has an opening shape formed by an arc and a straight line connecting both ends of the arc at two opposing locations on the top plate 22f. When the cap member 22B is attached to the bridge 22A, the front wall through-hole 22h can be viewed from the front in the axial direction, and the front end region from the outer circumferential surface to the top surface of the first cylindrical portion 18 can be seen.

[0030] By providing the front wall through-hole 22h in the cap member 22B, when washing with tap water, water that enters from between the first cylindrical part 18 and the second cylindrical part 20 can be drained out of the reel through the front wall through-hole 22h of the top plate 22f, making it less likely for the one-way clutch 32 described above to be submerged in water.

[0031] In this embodiment, multiple (two) front wall through holes 22h are formed in the top plate 22f of the cap member 22B. These are formed in positions that are symmetrical (point-symmetrical) with respect to the insertion hole 22e through which the spool shaft 5A is inserted, so that the rotational balance of the rotor 10 does not decrease.

[0032] Furthermore, since the two front wall through-holes 22h formed at the aforementioned locations are formed to extend radially between the pair of support arms 11 and 12, a reduction in rotor strength can be efficiently suppressed. While there are no limitations on the position or number of front wall through-holes 22h formed in the top plate 22f, it is preferable to form them radially inward relative to the outer circumferential surface of the first cylindrical portion 18. Forming them in this position allows water to flow more easily along the outer circumference of the first cylindrical portion 18 (improving water permeability).

[0033] The through-holes in the front wall of the cap member 22B are not limited to the top plate 22f as described above, but may also be formed in other parts of the cap member 22B. For example, by forming through-holes (drainage openings; not shown) on the surface of the arc-shaped hanging wall 22g so as to open radially, it is possible to further improve water permeability and make it easier for water to flow when the reel is turned sideways.

[0034] When the cap member 22B is attached to the bridge 22A, the annular flange portion 22d is locked against the upper edge of the arcuate wall 21e of the cylindrical wall 21, and the pair of arcuate walls 22g that hang down in an arc shape are locked against the semi-annular frames 21c and 21d, respectively, closing the upper side of the cylindrical wall opening 21a.

[0035] By applying the top plate 22f of the cap member 22B to the surface of the bridge 22A and welding the boss 22k protruding from the hole 20b, the cap member 22B is attached to the bridge 22A, and the front wall through hole 22h serves as a drainage opening. This is the result.

[0036] Furthermore, when the cap member 22B is attached to the bridge 22A, it is preferable that the front wall through-hole 22h is located in front of the cylindrical wall opening 21a. With this configuration, water can easily flow from the cylindrical wall opening 21a to the front wall through-hole 22h. Also, it is preferable that the upper end of the cylindrical wall opening 21a is formed to be substantially flush with the front wall 22 of the second cylindrical portion. With this configuration, it is preferable that water does not easily enter the one-way clutch 32 housed in the first cylindrical portion 18.

[0037] The arc-shaped bridge 25 connects both sides of the lower end of the arc-shaped wall 21e of the cylindrical wall 21 with a frame structure, and the connected portion defines the opening at the rear end of the second cylindrical portion 20. As a result, the rotor body 10 is effectively reinforced at the pair of support arms 11 and 12 that are subjected to large loads, making it possible to reduce the weight as much as possible while maintaining the necessary strength.

[0038] According to the above configuration, even if water enters the reel body, the opening 21a in the cylindrical wall of the second cylindrical section 20 and the through-hole 22h in the front wall of the front wall 22 improve water permeability and prevent water from entering the first cylindrical section 18 (water retention is suppressed), resulting in a spinning reel for fishing with improved water resistance. Furthermore, even if sand and dust enter, they can be easily removed by washing, without impairing the performance of the reel. In addition, in this embodiment, the first cylindrical section 18 and the second cylindrical section 20 are provided with a labyrinth structure 60 that prevents water from moving in a straight line, thereby preventing water from entering the first cylindrical section 18 and reliably preventing water from entering the one-way clutch 32 housed in the first cylindrical section 18.

[0039] In this case, it is preferable that the front wall through-hole 22h of the cap member 22B be formed radially outward with respect to the labyrinth structure 60, which is provided as follows, and in particular the circumferential wall 73 that forms the entrance side of the labyrinth structure 60, thereby reliably preventing water from entering the one-way clutch 32.

[0040] The labyrinth structure 60 of this embodiment will be described below with reference to Figures 3 and 5. The labyrinth structure 60 of this embodiment includes a cylindrical first mounting body 70 attached to the outer circumferential surface of the first cylindrical portion 18, and a substantially disc-shaped second mounting body 80 attached to the central region of the bridge 22A of the second cylindrical portion 20. These two components work together to suppress the intrusion of water into the interior.

[0041] Specifically, on the front side of the first mounting body 70, a plurality of circumferential walls 72, 73 are provided concentrically and at predetermined intervals from a central opening (which constitutes a circumferential wall) 71 through which the spool shaft 5A is inserted. This first mounting body 70 is fixed, for example, by press-fitting and bonding it to the outer circumferential surface of the first cylindrical portion 18. This first mounting body 70 may be formed separately from the first cylindrical portion 18 and integrated with the outer circumferential surface of the first cylindrical portion 18, or it may be formed integrally with the first cylindrical portion 18.

[0042] The rear side of the second mounting body 80 is provided with a plurality of circumferential walls 82, 83 adjacent to a central opening (forming a circumferential wall) 81 through which the spool shaft 5A is inserted, arranged concentrically and at predetermined intervals. This second mounting body 80 is fixed, for example, by press-fitting and bonding it to a cylindrical central projection formed on the back surface of the bridge 22A.

[0043] Furthermore, the method of attaching the first mounting body 70 and the second mounting body 80 may be a structure that fixes them in place by screws or the like.

[0044] The first mounting body 70 is attached to the first cylindrical portion 18, and the second mounting body 80 is attached to the bridge 22A When attached to the back surface, each of the circumferential walls 72, 73 and the circumferential walls 82, 83 enter the gaps between the circumferential walls on the other side, and the circumferential walls 72, 73, 82, 83 are in an adjacent state. As a result, a labyrinth structure is formed in which the intrusion direction of the infiltrating water bends, making it difficult for water to pass through the gaps between the circumferential walls of each mounting body, and it becomes possible to suppress water from intruding inside. In this case, the number of formed circumferential walls is not limited, but it is preferable to form two or more on each mounting body so that at least three or more bends can be obtained.

[0045] Also, for the labyrinth structure 60 described above, it is preferable to form the gap between the circumferential walls narrower on the outer side in the radial direction (the side where water infiltrates). That is, as shown in FIG. 7, for the gap G1 between the adjacent circumferential walls 73, 83 on the outer side in the radial direction, it is preferable to form it narrower (G1 < G2) than the gap G2 between the adjacent circumferential walls 72, 83 on the inner side in the radial direction. According to such a configuration, it becomes difficult for water to enter at the entrance portion where water first infiltrates, and the waterproofness can be enhanced. Note that such a relationship of the gaps may be configured by other circumferential wall portions where water infiltrates while bending.

[0046] Also, as shown in FIG. 8, regarding the gap G3 formed by the central circumferential walls 71, 81 among the plurality of adjacent circumferential walls constituting the labyrinth structure, it is preferable to form the water intrusion side narrower. According to such a configuration, even if water intrudes, a wide gap does not continue throughout, so the momentum of water immersion can be stopped, and the waterproofness can be enhanced. Note that such a gap may be configured by forming the gap between the central circumferential walls 71, 81 narrower than the gaps formed by the other circumferential walls, or may be a configuration in which the water intrusion side is narrowed in the middle of the water intrusion path.

[0047] Furthermore, it is preferable that the labyrinth structure 60 is formed such that the position P1 of the front edge of the radially outer circumferential wall 73 among the adjacent circumferential walls is positioned forward of the front end position P2 of the first cylindrical portion 18. With this configuration, even when cleaning with the spool shaft in the vertical direction (reel in the vertical direction), the water is more easily drained radially outward, thus preventing water from accumulating and improving water resistance.

[0048] The present invention can be modified in various ways beyond the embodiments described above. Other embodiments will be described below. In the embodiments described below, the same reference numerals are used for the same components as in the embodiments described above.

[0049] Figure 9 shows a second modified example of the rotor, where (a) is a perspective view and (b) is a front view from the axial direction. In this modified example, the front wall 22 is integrally formed with the second cylindrical portion 20 without providing the cap member 22B described above.

[0050] In other words, the front wall 22 is composed of the bridge 22A of the second cylindrical portion 20, and a top plate frame 22fa of a predetermined shape is formed on the inner surface of the annular wall 22ca at the front end of the second cylindrical portion 20, thereby forming a plurality (four) of front wall through holes 22ha. Preferably, the plurality of front wall through holes 22ha of the top plate frame 22fa are formed symmetrically with respect to the central opening 22a of the bridge 22A (insertion hole for inserting the spool shaft), and in this modified example, four substantially triangular front wall through holes 22ha are formed.

[0051] Figure 10 shows a third modified example of the rotor, where (a) is a perspective view and (b) is a front view from the axial direction. In this modified example, the front wall 22 is integrally formed with the second cylindrical portion 20, similar to the second embodiment.

[0052] Furthermore, the top plate frame 22fa is designed to have two roughly rectangular front wall through-holes 22ha. The front wall through-hole 22ha is formed symmetrically with respect to the central opening 22a of the bridge 22A.

[0053] Figure 11 shows a fourth modified example of the rotor, where (a) is a perspective view and (b) is a front view from the axial direction. The front wall 22 of this modified example is integrally formed with the second cylindrical portion 20, similar to the second and third modified examples.

[0054] Furthermore, the top plate frame 22fa is formed such that two approximately semicircular front wall through-holes 22ha are formed, and the front wall through-holes 22ha are formed symmetrically with respect to the central opening 22a of the bridge 22A.

[0055] As shown in the second to fourth modifications described above, the front wall 22 may have a structure without a cap member, and the shape, size, and number of through holes in the front wall can be modified as appropriate.

[0056] Figure 12 shows the internal structure of a second embodiment of a spinning reel for fishing. In the embodiment described above, the first cylindrical portion 18 only needs to house the one-way clutch 32, and its housing configuration and its arrangement with the first mounting body 70 of the labyrinth structure 60 can be modified as appropriate.

[0057] In the embodiment shown in Figure 12, the first cylindrical portion 18 is composed of a cylindrical wall 18A that houses the one-way clutch 32 and a first mounting body 70A that covers the outer circumferential surface of the cylindrical wall 18A, and the first cylindrical portion 18 is composed including the first mounting body 70A. Furthermore, the cylindrical wall 18A is separate from the reel body 2 and is provided on the reel body, housing the one-way clutch 32. In this case, the cylindrical wall 18A may house the one-way clutch 32 along its entire circumference, or it may have an opening formed along the circumferential direction in a part of its circumference. Furthermore, the cylindrical wall 18A may be separate from the first mounting body 70A and attached to the inner (or outer) surface of the first mounting body 70A, or it may be integrally formed with the first mounting body 70A.

[0058] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above and can be modified in various ways. For example, the shape, formation position, and number of the front wall through-holes 22h and 22ha can be modified as appropriate, and the configuration of the rotor 10 and the front wall 22 can also be modified as appropriate.
