Description

[0001] The present invention relates to a spinning reel, more particularly to a spinning reel capable of casting a fishing line in a forward direction.

[0002] Conventional spools generally have a spool body and a skirt portion provided in the rear portion of the spool body. The rotor has a wall portion through which the spool shaft penetrates, and a cylindrical portion, at least a portion of which radially overlaps the skirt portion on the inside of the skirt portion. The radial overlap of the skirt portion and the cylindrical portion prevents the fishing line from penetrating the skirt portion and from becoming entangled with the spool shaft due to the fishing line penetrating the skirt portion (see JP 4 324 462 B2).

[0003] Such coils are disclosed, for example, in EP 3 498 092 A1 and US 2010 0 327 097 A1.

[0004] To prevent fishing line from entering the skirt portion of the spool by overlapping the cylindrical portion of the rotor with a portion of the skirt portion in the radial direction, it is necessary to overlap a portion of the cylindrical portion with the skirt portion in the radial direction, even when the spool is moved to the furthest forward position. Therefore, for example, in a spinning reel where the longitudinal movement of the spool is large, the cylindrical portion is formed with a long axial length.

[0005] If the wall portion is located at the front end of the cylindrical portion, when the cylindrical portion has a long axial length, the cylindrical portion has a large internal space, and the amount of water that can enter the cylindrical portion increases. Therefore, in JP 4 324 462 B2, the cylindrical portion protrudes further forward than the wall portion. In this case, if water penetrates the cylindrical part and the water accumulates inside the cylindrical part, there is a risk that the water inside the cylindrical part will penetrate into the reel body.

[0006] For this purpose, EP 3 498 092 A1, for example, provides drainage holes in the coil body that allow water to drain out of the cylindrical section.

[0007] An object of the present invention is to reduce or prevent the ingress of water from the cylindrical part of the rotor into the interior of the reel body, as well as to prevent the ingress of fishing line into the skirt portion of the spool.

[0008] The spinning reel according to one aspect of the present invention can cast (reel) the fishing line in the forward direction. The spinning reel includes a reel body, a handle, the spool shaft, the spool, a rotor, and a drain hole. The handle is rotatably supported by the reel body. The spool shaft reciprocates the reel body according to the rotation of the handle. The spool moves together with the spool shaft. The spool has a spool body and a skirt portion disposed in the rear portion of the spool body and having a larger diameter than the outer diameter of the spool body. The rotor can rotate relative to the reel body.The rotor includes a wall portion having a smaller diameter than the outer diameter of the skirt portion and through which the spool shaft penetrates in the axial direction, a first cylindrical portion projecting forward from the wall portion and at least partially overlapping the skirt portion of the spool in the radial direction, and a second cylindrical portion projecting rearward from the wall portion. The drainage hole extends from the interior to the exterior of the first cylindrical portion of the rotor. The drainage hole includes an inclined portion that slopes rearward in a direction away from the spool shaft. Since water draining from the drainage hole is more easily directed outward, water is less likely to remain in the skirt portion of the spool in this embodiment.

[0009] In this spinning reel, since at least a portion of the first cylindrical portion of the rotor radially overlaps a portion of the skirt portion of the spool, the penetration of the fishing line into the skirt portion of the spool can be prevented. Furthermore, when water enters the first cylindrical portion of the rotor from the front, the water that has entered the first cylindrical portion is discharged from the drainage hole to the outside of the first cylindrical portion. Thus, since it is possible to prevent or reduce the accumulation of water inside the first cylindrical portion, the penetration of water from the first cylindrical portion into the interior of the reel body can be prevented or reduced.

[0010] Preferably, the drainage hole extends along the circumferential direction of the first cylindrical portion. In this embodiment, it is possible to effectively and promptly drain the water that has penetrated into the first cylindrical portion to the outside.

[0011] Preferably, the drainage hole is formed at a boundary portion between the wall portion and the first cylindrical portion. In this embodiment, the intrusion of water from the first cylindrical portion into the interior of the roller body can be further reduced because it is possible to reduce or prevent the accumulation of water on a front surface portion of the wall portion within the first cylindrical portion.

[0012] Preferably, the rear end portion of the inclined portion of the drainage hole is connected to the outer peripheral portion of the second cylindrical portion. In this embodiment, the water leaking from the drainage hole is more easily directed to the outside.

[0013] Preferably, the rotor also includes a pair of rotor arms that oppose each other on the radially outer side of the first cylindrical portion and the second cylindrical portion. The drainage hole is arranged in a position so as not to overlap the pair of rotor arms in the radial direction. In this embodiment, the water flowing out of the drainage hole can be easily drained outward without being interfered with by the rotor arms.

[0014] By the present invention, it is possible to reduce or prevent the entry of water from the cylindrical part of the rotor into the interior of the reel body and also to prevent the penetration of fishing line into the skirt part of the spool.

[0015] A more complete appreciation of the invention and many of the attendant advantages will be readily attained as the same becomes better understood from the following detailed description when considered in conjunction with the accompanying drawings, in which: Fig. 1 is a side view of a spinning reel utilizing an embodiment of the present invention; Fig. 2 is a cross-sectional view of the spinning reel; Fig. 3 is a perspective view of a rotor; and Fig. 4 is a cross-sectional view of the rotor.

[0016] A spinning reel 100 employing an embodiment of the present invention is capable of casting a fishing line in a forward direction. Fig. 1 is a side view of the spinning reel 100. As in Fig. 1, the spinning reel 100 comprises a reel body 2, a handle 3, a spool shaft 4 (see Fig. 2), a coil 5, a rotor 6 and a drainage hole 7 (see Fig. 3).

[0017] In the following description, the direction in which the fishing line is cast (unwound) during fishing is referred to as the front, and the opposite direction is referred to as the rear. Furthermore, left and right mean left and right as viewed from the rear of the spinning reel 100. Furthermore, the direction in which the spool shaft 4 extends is referred to as the axial direction, the direction orthogonal to the spool shaft 4 is referred to as the radial direction, and the direction around the axis of the spool shaft 4 is referred to as the circumferential direction. The axial direction in the present embodiment coincides with the longitudinal direction.

[0018] Fig. 2 is a cross-sectional view of the spinning reel 100. The reel body 2 includes a reel body portion 2a and a cylindrical portion 2b. The reel body portion 2a has an interior space surrounding a known swing mechanism 12 and a not-shown portion of a known rotor drive mechanism that drives the rotor 6. The cylindrical portion 2b extends axially from the front portion of the reel body portion 2a. A one-way clutch 14 is disposed within the cylindrical portion 2b.

[0019] The handle 3 is rotatably supported by the reel body 2. In the present embodiment, the handle 3 is mounted on the left side of the reel body 2. The handle 3 can also be mounted on the right side of the reel body 2.

[0020] The spool shaft 4 is supported by the longitudinally extending reel body 2. The spool shaft 4 moves the reel body 2 back and forth through the swing mechanism 12 according to the rotation of the handle 3.

[0021] The spool 5 is mounted on the spool shaft 4 by a nut member (not shown) that cuts into the distal end of the spool shaft 4 and moves integrally with the spool shaft 4. That is, the spool 5 moves together with the spool shaft 4 reciprocally back and forth with respect to the reel body 2. The Fig. 1 and Fig. The position of the spool 5 shown in Fig. 2 indicates the position in which the spool 5 has moved furthest backward with respect to the reel body 2.

[0022] The spool 5 has a spool body 5a and a skirt portion 5b. The fishing line is wound around the outer circumference of the spool body 5a. The skirt portion 5b is formed integrally with the spool body 5a in the rear portion of the spool body 5a. The skirt portion 5b has a cylindrical shape and extends in the axial direction. The outer diameter of the skirt portion 5b is larger than the outer diameter of the spool body 5a.

[0023] The rotor 6 can rotate relative to the reel body 2 and winds the fishing line around the spool body 5a of the spool 5 in accordance with the rotation of the handle 3. The rotor 6 is connected to a gear ring 16, to which the rotation of the handle 3 is transmitted so that they can rotate together. The rotation of the handle 3 is transmitted to the gear ring 16 via the rotor drive mechanism.

[0024] Fig. 3 is a perspective view of the rotor 6. Fig. 4 is a cross-sectional view of the rotor 6. As shown in the Fig. As shown in Figures 2 to 4, the rotor 6 includes a wall portion 61, a first cylindrical portion 62, a second cylindrical portion 63, and a pair of rotor arms 64. The wall portion 61 is disc-shaped and extends in the radial direction. The wall portion 61 has a smaller diameter than the outer diameter of the skirt portion 5b of the spool 5 and is located radially inward of the skirt portion 5b. In the center of the wall portion 61, there is a through hole 61a through which the spool shaft 4 extends in the axial direction. The wall portion 61 is connected to the ring gear 16 so as to be integrally rotatable by a nut member 18 that is screwed onto the distal end of the ring gear 16.

[0025] The first cylindrical portion 62 is cylindrical and protrudes forward from the outer end portion of the wall portion 61. Thus, the first cylindrical portion 62 is open to the front and covered by the wall portion 61 on the rear. At least a part of the first cylindrical portion 62 overlaps the skirt portion 5b of the spool 5 in the radial direction. Specifically, when the spool 5 has moved to the front position with respect to the reel body 2 and when the spool 5 has moved to the rearmost position with respect to the reel body 2, at least a part of the first cylindrical portion 62 overlaps the skirt portion 5b of the spool 5b in the radial direction. That is, the first cylindrical portion 62 is disposed radially inward of the skirt portion 5b of the spool 5b, and at least a portion thereof is disposed opposite to the inner peripheral portion of the skirt portion 5b of the spool 5b.Thereby, the penetration of the fishing line into the skirt portion 5b of the spool 5 through the first cylindrical portion 62 can be prevented.

[0026] In the present embodiment, the first cylindrical portion 62 is a separate body from the wall portion 61. In particular, the first cylindrical portion 62, as shown in the Fig. 2 and Fig. 3, a fixing portion 62a protrudes radially inward of the first cylindrical portion 62. The fixing portion 62a is fastened to the wall portion 61 with a screw element 20. The first cylindrical portion 62 is thereby fastened to the wall portion 61.

[0027] The second cylindrical portion 63 is cylindrical and protrudes rearward from the outer end portion of the wall portion 61. Accordingly, the second cylindrical portion 63 is open rearward, and the front side is covered by the wall portion 61. The first cylindrical portion 62 is arranged radially inward of the skirt portion 5b of the coil 5. As shown in Fig. 2, at least a portion of the second cylindrical portion 63 is disposed opposite the inner peripheral portion of the skirt portion 5b of the spool 5b when the spool 5 has moved to the rearmost position relative to the reel body 2. In this embodiment, the second cylindrical portion 63 does not overlap the skirt portion 5b of the spool 5 in the radial direction when the spool 5 has moved to the front position with respect to the reel body 2. However, a portion of the second cylindrical portion 63 may be configured to overlap the skirt portion 5b of the spool 5 in the radial direction when the spool 5 has moved to the front position with respect to the reel body 2. The second cylindrical portion 63 is formed integrally with the wall portion 61. The outer diameter of the second cylindrical portion 63 is approximately equal to the outer diameter of the first cylindrical portion 62.The cylindrical portion 2b of the roller body 2 is accommodated in the interior of the second cylindrical portion 63.

[0028] As in the Fig. As shown in Figures 1 to 3, the pair of rotor arms 64 are arranged in opposite positions radially outward from the first cylindrical portion 62 and the second cylindrical portion 63. The pair of rotor arms 64 are formed integrally with the second cylindrical portion 63. The pair of rotor arms 64 are curved forward from the rear end portion of the second cylindrical portion 63 so as to be radially spaced from the first cylindrical portion 62 and the second cylindrical portion 63.

[0029] As in the Fig. 3 and Fig. As shown in Figure 4, the drainage hole 7 extends from the interior to the exterior of the first cylindrical portion 62 of the rotor 6. In this embodiment, the drainage hole 7 radially penetrates the first cylindrical portion 62 at a boundary portion between the wall portion 61 and the first cylindrical portion 62. The drainage holes 7 are arranged at two opposite locations at a distance in the circumferential direction. The drainage hole 7 extends along the circumferential direction of the first cylindrical portion 62 and is arranged in a position that does not overlap the pair of rotor arms 64 in the radial direction.

[0030] The drainage hole 7 has an inclined portion 7a. The inclined portion 7a extends along the circumferential direction of the first cylindrical portion 62 and is inclined rearward in a direction away from the spool shaft 4. In this embodiment, the inclined portion 7a is formed integrally with the first cylindrical portion 62 at the rear end portion of the first cylindrical portion 62. The inclined portion 7a is arranged in a position overlapping the first cylindrical portion 62 in the axial direction. The inclined portion 7a is mounted on a mounting portion 61b arranged at a boundary portion between the wall portion 61 and the second cylindrical portion 63. The fixing portion 61b has a shape corresponding to the inclined portion 7a and is inclined rearward in a direction away from the spool shaft 4.The rear end portion of the inclined portion 7a is seamlessly connected to the outer peripheral portion of the second cylindrical portion 63. That is, the inclined portion 7a is configured such that the outer peripheral surface of the rear end portion thereof is flush with the outer peripheral surface of the second cylindrical portion 63.

[0031] In the spinning reel 100 configured as described above, when water (including sea water) enters the first cylindrical portion 62 of the rotor 6 from the front, the water that has entered the first cylindrical portion 62 is discharged from the drainage hole 7 to the outside of the first cylindrical portion 62 as shown by the arrow in Fig.4. Since it is thus possible to reduce or prevent the accumulation of water inside the first cylindrical portion 62, the intrusion of water from the first cylindrical portion 62 into the interior of the reel body 2 can be reduced or prevented. Furthermore, since the drainage hole 7 is arranged at a boundary portion between the wall portion 61 and the first cylindrical portion 62, it is possible to reduce or prevent the accumulation of water at the front surface portion of the wall portion 61 within the first cylindrical portion 62. Thereby, the intrusion of water from the first cylindrical portion 62 into the interior of the reel body 2 can be further reduced.In addition, by disposing the inclined portion 7a in the drainage hole 7, the water leaking from the drainage hole 7 is more easily guided outward along the outer peripheral portion of the second cylindrical portion 63, and the water is less likely to remain in the skirt portion 5b of the spool 5b.

[0032] One embodiment of the present invention is described above, but the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the invention. In particular, the various embodiments and modified examples described in the present specification can be arbitrarily combined.

[0033] In the above-described embodiment, the drainage hole 7 is arranged at a boundary portion between the wall portion 61 and the first cylindrical portion 62, but the position and shape of the drainage hole 7 are not limited to the above-described embodiment. It is sufficient for the drainage hole 7 to extend from the inner space to the outer space of the first cylindrical portion 62. For example, the drainage hole 7 may radially penetrate into the intermediate portion of the first cylindrical portion 62 or connect the front surface portion of the wall portion 61 to the outer space of the first cylindrical portion 62. It is also sufficient for at least one of the drainage holes 7 to be provided. Furthermore, it is not necessary to provide the drainage hole 7 with the inclined portion 7a.

[0034] In the embodiment described above, the first cylindrical portion 62 and the wall portion 61 are separate bodies, but the first cylindrical portion 62 and the wall portion 61 may be a single unitary member.
