Description

[Technical Field]

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

[0002] A typical waterproof structure provided in conventional spinning reels comprises a cylindrical member fitted onto the outer periphery of a spool shaft provided in the reel body, and a rotor provided at the front of the cylindrical member, with a lip seal of a sealing member that provides waterproofing around the entire circumference between the cylindrical member and the rotor, and abuts the rotor in a liquid-tight manner in the radial direction perpendicular to the spool shaft (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5961407 [Patent Document 2] Patent No. 6261971 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional designs where the lip seal is extended in the radial direction, the lip's elastic deformation (tension force) is increased to contact the object in order to prevent a decrease in waterproofing due to eccentricity between the attached parts. This increases friction torque and reduces rotational efficiency, which leaves room for improvement.

[0005] The present invention was made in consideration of these circumstances, and its purpose is to provide a waterproof structure and spinning reel that can reduce torque by suppressing the effects of eccentricity and making it difficult for water pressure to act on the main lip itself, thereby suppressing the increase in torque caused by the waterproof seal acting on the spinning reel. [Means for solving the problem]

[0006] (1) The waterproof structure of the present invention is a waterproof structure provided for a spinning reel that includes a cylindrical member disposed on the outer periphery of a spool shaft and a rotor provided at the front of the cylindrical member, and is characterized in that it has a sealing member that provides waterproofing around the entire circumference between the cylindrical member and the rotor, the sealing member having a main lip that abuts liquid-tightly against the rotor in the axial direction of the spool shaft, and at least one of the rotor and the cylindrical member having an annular wall portion that covers the contact portion where the main lip abuts around the entire circumference from the outer periphery.

[0007] According to the waterproof structure of the present invention, the main lip of the seal member and the rotor are in liquid-tight axial contact, and the annular wall portion provided on the outer periphery of the contact area forms a labyrinth, which makes it difficult for water pressure to act on the main lip, eliminating the need for increased elastic deformation of the lip. This suppresses the increase in torque caused by the waterproof seal acting on the spinning reel, thereby achieving lower torque.

[0008] Furthermore, the present invention can prevent problems such as the need for precision in centering the seal member during reel assembly, which is the case in conventional cases where the main lip of the seal member makes contact in the radial direction, and a decrease in waterproofness when the seal member is misaligned from the specified position, thereby improving assembly.

[0009] (2) It is preferable that the seal member has an auxiliary lip between the contact portion and the annular wall portion, the auxiliary lip extending in the axial direction of the spool with a gap provided with respect to the rotor.

[0010] In this case, by providing an auxiliary lip between the main lip and the annular wall portion, water pressure is further prevented from acting on the main lip, thereby improving waterproof performance.

[0011] (3) A lubricant may be filled in an area surrounded by the main lip, the auxiliary lip, and the rotor.

[0012] In this case, since the region is filled with a lubricant, it is possible to increase the rotational efficiency, further reduce torque, and improve waterproof performance.

[0013] (4) The surface of the annular wall may be treated to be water repellent.

[0014] In this case, the water-repellent effect of the annular wall portion can prevent water from entering the inner periphery, and further, water pressure can be made less likely to be applied to the main lip.

[0015] (5) The main lip may be characterized in that it gradually extends from an inner periphery side to an outer periphery side in the radial direction as it moves axially toward the rotor.

[0016] In this case, the tip of the main lip, that is, the position that comes into contact with the rotor, is disposed closer to the outer periphery than the base end, so that the water pressure resistance of the main lip can be improved.

[0017] (6) A spinning reel according to the present invention is characterized by having the waterproof structure according to any one of (1) to (5).

[0018] The present invention can provide a spinning reel that has the above-mentioned waterproof structure. [Effects of the Invention]

[0019] The waterproof structure and spinning reel of the present invention reduce the effects of eccentricity and make it difficult for water pressure to act on the main lip itself, thereby suppressing the increase in torque caused by the waterproof seal acting on the spinning reel and achieving low torque.

[0021] Hereinafter, embodiments of a waterproof structure and a spinning reel according to the present invention will be described with reference to the drawings. Note that in each drawing, the scale of each component may be changed as necessary to make each component large enough to be visible.

[0022] As shown in FIGS. 1 and 2, the spinning reel 1 of this embodiment includes a reel body 10, a handle 2 rotatably supported on the reel body 10, a rotor 3, and a spool 4.

[0023] The rotor 3 is rotatably supported at the front of the reel body 10. The spool 4 winds fishing line onto its outer periphery and is positioned at the front of the rotor 3 so that it can move back and forth. In FIG. 1, the handle 2 is attached to the left side of the reel body 10 when in use. The handle 2 can be attached to either the left or right side of the reel body 10.

[0024] The handle 2 has a handle grip 21 and a handle arm 22 to the tip of which the handle grip 21 is rotatably attached. A handle shaft 23 (described later) is formed at the base end of the handle arm 22 so as to extend in a direction intersecting the handle arm 22, and is non-rotatably attached to a handle shaft 23 (described later).

[0025] The reel unit 10 has a reel body 11 having an internal space, and a cover member 12 that is removably attached to the reel body 11 to close the space in the reel body 11.

[0026] The reel body 11 is made of, for example, an aluminum alloy, and has a T-shaped rod mounting leg 110 that extends forward and backward integrally formed at the top. As shown in Figure 2, the reel body 11 contains within its interior space a rotor drive mechanism 5 that rotates the rotor 3 in conjunction with the rotation of the handle 2, and an oscillating mechanism 6 that moves the spool 4 forward and backward to evenly wind up the fishing line.

[0027] A circular flange 13 is formed at the front end of the reel body 11 and the cover member 12. The cover member 12 is made of, for example, an aluminum alloy, and is fastened to the reel body 11 with screws at multiple locations. A cylindrical portion 14 is provided on the front surface of the flange portion 13, the outer periphery of which projects forward.

[0028] The reel body 11 accommodates, from the front, a first bearing 15A through which a spool shaft 41 of the spool 4 (described later) passes and which rotatably supports the rear end of the spool shaft 41. The reel body 11 and the cover member 12 each have a circular through-hole (not shown) through which the handle shaft 23 can be inserted. A rolling bearing 24 that rotatably supports the handle shaft 23 is accommodated around the through-hole on the inner surface of the reel body 11 and the cover member 12.

[0029] As shown in Figures 1 and 2, the rotor 3 has a rotor body 31, a bail arm 32 attached to the tip of the rotor body 31 so as to be able to swing freely between a line-releasing position and a line-winding position, and a bail flip mechanism 33 attached to the rotor body 31 for returning the bail arm 32 from the line-releasing position to the line-winding position.

[0030] As shown in Figure 2, the rotor body 31 has a cylindrical portion 310 that is rotatably mounted on the reel body 11 around the spool shaft 41. As shown in Figure 1, the bail arms 32 are provided on the sides of the cylindrical portion 310, facing each other. The cylindrical portion 310 and the bail arms 32 are made of, for example, an aluminum alloy and are molded as a single unit. A bail 34, which guides the fishing line to the spool 4 and is made of a wire that is curved in a generally U-shape, is fixed between the tips of the opposing bail arms 32.

[0031] 3, a front wall 313 is formed at the front of the cylindrical portion 310. A through hole 311a is formed in the center of the front wall 313, and the front portion 16a of the pinion gear 16 and the spool shaft 41 pass through this through hole 311a. A rotor fixing cover 35 for fixing the rotor 3 is disposed in front of the front wall 313.

[0032] Inside the cylindrical portion 310 of the rotor 3, a reverse rotation prevention mechanism 50 for prohibiting or releasing the reverse rotation of the rotor 3 is disposed. The reverse rotation prevention mechanism 50 has a roller clutch 51, which is a roller-type one-way clutch attached to the inner periphery of the cylindrical portion 14 of the reel body 11, and a stopper knob (not shown) that is located at the bottom of the reel body 11 and switches the roller clutch 51 between an activated state and a deactivated state. The roller clutch 51 has an outer ring attached to the front side of the cylindrical portion 14 and an inner ring attached to the outer periphery of the pinion gear 16. Here, the roller clutch 51 is switched between an activated state and a deactivated state by swinging the stopper knob left and right.

[0033] As shown in Figure 1, the spool 4 is disposed between the opposing bail arms 32 of the rotor 3, and is attached to the tip of the spool shaft 41 via a drag mechanism 60 (see Figure 2). The spool 4 has a bobbin trunk 42 around which fishing line is wound, a skirt portion 43 formed integrally with the rear portion of the bobbin trunk 42, and a flange portion 44 formed integrally with the front end of the bobbin trunk 42.

[0034] As shown in Figure 2, the rotor drive mechanism 5 has a handle shaft 23 to which the handle 2 is non-rotatably attached, a drive gear 18 that rotates together with the handle shaft 23, and a pinion gear 16 that meshes with this drive gear 18.

[0035] The pinion gear 16 is cylindrical and made of stainless steel alloy, and a front portion 16a of the pinion gear 16 passes through the center of the rotor 3 and is fixed to the rotor 3 by a nut member 19. A rear portion 16b and a middle portion 16c of the pinion gear 16 are rotatably supported by the reel body 10 via a first bearing 15A and a second bearing 15B, which are rolling bearings, respectively.

[0036] The pinion gear 16 is attached to the reel body 10 so as to be rotatable about an axis that extends along the axial direction of the fishing rod, and a front portion 16a of the pinion gear 16 passes through the center (through-hole 311a) of the rotor 3 and is fixed to the rotor 3 by a nut member 19. The pinion gear 16 has a cylindrical portion 16A through whose inner periphery the spool shaft 41 passes with a gap, and a toothed portion 16B that is provided on the outer periphery of the rear portion of the cylindrical portion 16A and meshes with the drive gear 18. The outer periphery of the front portion 16a of the cylindrical portion 16A of the pinion gear 16 is attached so as to be non-rotatable relative to the rotor 3.

[0037] The cylindrical portion 16A of the pinion gear 16 is a cylindrical member made of a stainless steel alloy, and a rear portion 16b and a middle portion 16c are rotatably supported by the reel body 10 via a first bearing 15A and a second bearing 15B, respectively. A spool shaft 41 passes through the interior of the cylindrical portion 16A. A gap is formed between the cylindrical portion 16A and the spool shaft 41.

[0038] The toothed portion 16B is formed in a helical shape on the outer periphery between the rear portion 16b and the middle portion 16c of the cylindrical portion 16A, and meshes with the drive gear 18. The toothed portion 16B also meshes with the middle gear of the oscillating mechanism 6, which will be described later.

[0039] A male thread is formed on the outer peripheral surface of the front portion 16a of the pinion gear 16, and a nut member 19 is screwed onto this male thread. The nut member 19 is prevented from rotating by a retainer 19A. The retainer 19A is fixed to the front wall 313 of the rotor 3 by a plurality of screw members 19B attached from the front (see FIG. 3).

[0040] The spool shaft 41 is a shaft member made of a stainless steel alloy, and has a front end connected to the spool 4 via a drag mechanism 60, and a slider 61 of the oscillating mechanism 6 (described later) fixed to its rear end. The spool shaft 41 passes through the inner periphery of the pinion gear 16, and the outer periphery of the spool shaft 41 forward of the front portion 16a of the cylindrical portion 16A is rotatably supported by a third bearing 15C. The third bearing 15C is a rolling bearing attached to the outer periphery of the spool shaft 41.

[0041] The oscillating mechanism 6 is a mechanism for moving the spool shaft 41, which is connected to the center of the spool 4 via a drag mechanism 60, in the forward and backward direction, thereby moving the spool 4 in the same direction. The oscillating mechanism 6 is of a traverse cam type and includes an intermediate gear 62 that meshes with the teeth 16B of the pinion gear 16, a threaded shaft 66 that is attached to the reel body 11 so as to be rotatable about an axis parallel to the spool shaft 41, and a slider 61 that moves forward and backward as the threaded shaft 66 rotates. The rear end of the spool shaft 41 is attached to the slider 61 so as to be non-rotatable and non-movable in the axial direction.

[0042] A disk-shaped mounting plate 53 is provided coaxially with the spool shaft 41 on the front surface of the roller clutch 51. A seal member 7 for waterproofing the roller clutch 51 is attached to a front surface 53a of the mounting plate 53. That is, the seal member 7 waterproofs the entire periphery between the pinion gear 16 and the rotor 3.

[0043] A bottomed cylindrical cover member 17 (cylindrical member) for covering the front side of the roller clutch 51 is attached to the front end portion 14a of the cylindrical portion 14 of the reel body 11 via a first watertight ring 173 made of an O-ring made of synthetic resin. As shown in Fig. 4, a through-hole 17a, through which the spool shaft 41 and the pinion gear 16 are inserted, is formed in the center of the bottom wall 171 of the cover member 17. As shown in Fig. 5, the seal base end portion 72 of the seal member 7 is sandwiched between a rear surface 171b of the bottom wall 171 of the cover member 17 and a front surface 53a of the mounting plate 53, thereby fixing the seal member 7.

[0044] The cover member 17 has a cylindrical annular wall portion 172 that protrudes forward from a front surface 171a of a bottom wall 171. The annular wall portion 172 is disposed in a state where it enters a recessed groove 314 that is formed as an annular recess in a rear surface 313b of a front wall 313 of a cylindrical portion 310 of the rotor 3, thereby forming a labyrinth structure. In other words, the recessed groove 314 and the annular wall portion 172 form a labyrinth structure, which makes it difficult for water to enter the interior radially inward of the annular wall portion 172. The surface of the annular wall portion 172 may be water-repellent. Making the annular wall portion 172 water-repellent makes it more effective as a labyrinth structure.

[0045] The seal member 7 is a lip member made of an elastic synthetic resin such as nitrile rubber. As shown in Figures 4 and 5, the seal member 7 includes a seal main body 71, a seal base end portion 72 that is disposed on the outer circumferential side of the seal main body 71 and is sandwiched between the bottom wall 171 of the cover member 17 and the front surface 53a of the mounting plate 53, a main lip 73 that extends forward from the seal main body 71, and an auxiliary lip 74 that is disposed on the outer circumferential side of the main lip 73 and extends forward from the seal main body 71. The seal main body 71, seal base end portion 72, main lip 73, and auxiliary lip 74 are integrally molded.

[0046] 5, the seal body 71 is disposed inside the through hole 17a of the cover member 17. That is, the seal body 71 is interposed between the through hole 17a and the outer peripheral surface 315a of the inner peripheral wall 315 that extends rearward from the inner peripheral end of the front wall 313 of the rotor 3. The seal body 71 covers the entire front side of the roller clutch 51.

[0047] The main lip 73 is provided so that a lip tip 73a faces the front wall 313 of the rotor 3 in the axial direction and is in contact with the rear surface 313b of the front wall 313. The main lip 73 gradually extends from the inner circumferential side to the outer circumferential side in the radial direction as it approaches the front wall 313 of the rotor 3 in the axial direction. The main lip 73 abuts liquid-tightly against the front wall 313 of the rotor 3 in the axial direction of the spool shaft 41. Although FIG. 5 shows the lip tip 73a of the main lip 73 overlapping the front wall 313, the lip tip 73a is in liquid-tight contact with the rear surface 313b of the front wall 313 while being bent relative to the rear surface 313b.

[0048] The contact portion of the front wall 313 with which the lip tip 73a of the main lip 73 abuts is covered over the entire periphery from the outer periphery side by the annular wall portion 172 of the cover member 17.

[0049] The auxiliary lip 74 is disposed on the outer circumferential side with a gap therebetween relative to the main lip 73. The auxiliary lip 74 is disposed such that a lip tip 74a faces the rear surface 313b of the front wall 313 of the rotor 3 in the axial direction, and is in contact with or close to (close to) a convex portion 313c that convex rearward from the rear surface 313b of the front wall 313 (see FIG. 5 ). That is, a gap S1 of, for example, approximately 0.5 mm is formed between the lip tip 74a of the auxiliary lip 74 and the convex portion 313c. The lip tip 74a of the auxiliary lip 74 is located rearward of the lip tip 73a of the main lip 73.

[0050] In an area surrounded by the main lip 73 and auxiliary lip 74 of the seal member 7 and the front wall 313 of the rotor 3, a grease retaining portion 75 for retaining grease 8 (lubricant) is provided.

[0051] The grease retaining portion 75 is filled with grease 8 from a gap S1 between a lip tip 74a of the auxiliary lip 74 and the convex portion 313c of the front wall 313. The grease 8 is filled throughout the grease retaining portion 75, and a portion of it may be filled in a region 76 between the auxiliary lip 74 and the annular wall portion 172. The type of grease 8 as a lubricant can be selected as appropriate.

[0052] Next, the waterproof structure and the operation of the spinning reel 1 configured in this manner will be described in detail with reference to the drawings.

[0053] 3 and 5, in this embodiment, a waterproof structure including a seal member 7 is provided in the front portion of a cylindrical cover member 17 that houses the roller clutch 51, thereby preventing water from entering the inside of the roller clutch 51. That is, in this embodiment, the main lip 73 of the seal member 7 and the rotor 3 are brought into liquid-tight contact in the axial direction, and the annular wall portion 172 of the cover member 17 provided on the outer periphery of the contact portion forms a labyrinth, making it difficult for water pressure to act on the main lip 73. In other words, by bringing the main lip 73 into axial contact with the rotor 3, the contact pressure does not change significantly even if eccentricity occurs between them, so there is no need to increase the elastic deformation of the lip. This makes it possible to suppress an increase in torque acting on the spinning reel 1, thereby achieving low torque.

[0054] Furthermore, in this embodiment, as in the conventional case where the main lip 73 of the seal member 7 contacts in the radial direction, precision is required for centering the seal member 7 during reel assembly, and if the seal member 7 is misaligned from the specified position, the waterproof performance is reduced. This can be prevented, thereby improving assembly.

[0055] Furthermore, in this embodiment, the sealing member 7 is provided with an auxiliary lip 74 that extends in the axial direction of the spool shaft 41 with a gap between the contact portion between the front wall 313 of the rotor 3 and the sealing member 7 and the annular wall portion 172, thereby making it even more difficult for water pressure to act on the main lip 73, thereby improving waterproof performance.

[0056] Furthermore, in the waterproof structure according to this embodiment, the sealing member 7 is provided with a main lip 73 and an auxiliary lip 74, and the area surrounded by the rotor 3 is filled with grease 8, thereby increasing rotational efficiency, further reducing torque, and improving waterproof performance.

[0057] Furthermore, in this embodiment, by making the surface of the annular wall portion 172 water-repellent, the water-repellent effect of the annular wall portion 172 can prevent water from penetrating into the inner circumference, and further makes it difficult for water pressure to be applied to the main lip 73.

[0058] Furthermore, in this embodiment, the main lip 73 gradually extends radially from the inner periphery toward the outer periphery as it axially approaches the front wall 313 of the rotor 3, and the lip tip 73a of the main lip 73, i.e., the position that contacts the rotor 3, is positioned closer to the outer periphery than the base end, thereby improving the water pressure resistance of the main lip 73.

[0059] In this embodiment, since the seal of the lip seal portion has the greatest effect on improving torque in the waterproof structure, it is possible to achieve a reduction in torque in that portion.

[0060] The waterproof structure and spinning reel 1 of this embodiment configured as described above suppress the effects of eccentricity and make it difficult for water pressure to act on the main lip 73 itself, thereby suppressing the increase in torque caused by the waterproof seal acting on the spinning reel 1 and achieving low torque.

[0061] Although the waterproof structure and spinning reel according to the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The embodiments and their modifications include, for example, those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are equivalent.

[0062] For example, in this embodiment, the seal member 7 is configured such that the auxiliary lip 74 is provided between the main lip 73 and the annular wall portion 172, but this auxiliary lip 74 may be omitted.

[0063] Furthermore, in this embodiment, the cover member 17 is used as the cylindrical member on which the annular wall portion is provided, but it is not limited to the cover member 17. For example, in a configuration in which the cover member 17 is omitted, the cylindrical portion 14 that protrudes forward of the reel body 11 may be the cylindrical member, and a configuration in which the annular wall portion is provided on this cylindrical portion 14 may also be applied. In short, it is sufficient to have a waterproof structure that can prevent water from entering between the rotor 3 and the inside of the cylindrical member that houses the rotor drive mechanism 5 such as the roller clutch 51.

[0064] In this embodiment, the area (grease holding portion 75) surrounded by the main lip 73, the auxiliary lip 74, and the rotor 3 is filled with grease 8 (lubricant), but this lubricant can be omitted. Furthermore, the area filled with the lubricant is not limited to the area of ​​the grease holding portion 75 as described above, and it is also possible to fill the lubricant up to the area between the auxiliary lip 74 and the annular wall portion 172, for example.

[0065] Furthermore, in this embodiment, the annular wall portion 172 is configured to be provided on the cover member 17, which is a cylindrical member, but the portion where the annular wall portion is provided is not limited to being a cylindrical member, and the annular wall portion may be provided on a part of the rotor 3. That is, the annular wall portion provided on the rotor 3 is provided, for example, to protrude rearward in the axial direction from the front wall 313 of the rotor 3 and to cover the entire periphery of the contact portion with which the main lip 73 abuts, from the outer periphery side.

[0066] Furthermore, in this embodiment, the annular wall portion 172 is positioned in a state where it enters a groove 314 formed as an annular recess in the rear surface 313b of the front wall 313 of the cylindrical portion 310 of the rotor 3, thereby forming a labyrinth structure, but this is not limited to a configuration in which the groove 314 is provided in such a front wall 313, and a configuration in which the groove 314 is not formed is also possible.

[0067] Furthermore, in this embodiment, the surface of the annular wall portion 172 is water-repellent, but the present invention is not limited to this.

[0068] In addition, in this embodiment, the shape of the main lip 73 is such that it gradually extends from the inner circumferential side to the outer circumferential side in the radial direction as it approaches the front wall 313 of the rotor 3 in the axial direction, but it is not limited to such an inclined shape.

[0069] In addition, in this embodiment, the rotor body 31 (front wall 313) is targeted as the contact portion against which the main lip 73 abuts, but this is not limited to the rotor body 31, and the main lip 73 may also abut against a separate member that rotates integrally with the rotor 3.

[0070] In addition, the configurations of the reel body 11, handle 2, rotor 3, spool 4, such as their shapes and sizes, can be changed as appropriate. [Explanation of symbols]
