Description

[Technical Field]

[0001] The present invention relates to a handle knob for a fishing reel. [Background technology]

[0002] In conventional fishing reels, seawater can seep into the handle knob, get into the zipper, reel, etc., and when the water in the seawater evaporates, the components of the seawater, mainly consisting of tide, can stick to the bearings of the support shaft that rotatably supports the handle knob, preventing it from rotating normally, a phenomenon known as tide sticking.The end of the support shaft is thought to be the route through which seawater can seep in, and in order to prevent seawater from seeping in from the outside, a plug-shaped member, a cover, etc. is provided over the end of this support shaft (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2009-148173 [Patent Document 2] Patent Publication No. 2004-236541 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if the handle knob cover or the like is used as a waterproof plug as in Patent Documents 1 and 2, when actually fishing, external loads are applied, such as when gripping the handle knob tightly and turning the handle, etc. Therefore, loads such as bending and compression are applied to the plug-shaped part that is intended to be waterproof, and there is a possibility that the waterproof function will be impaired.

[0005] Furthermore, in Patent Documents 1 and 2, an O-ring is provided on the outer periphery of the part that fits into the hollow member to prevent water from getting in the hollow member, but there is a risk that the O-ring, which is made of rubber or the like, may deteriorate when it comes into contact with seawater that contains various components, mainly tides, and solids such as fine sand.

[0006] SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems of the prior art, and has as its object to provide a fishing reel handle knob that can prevent seawater from entering the handle knob. [Means for solving the problem]

[0007] (1) The present invention is a fishing reel handle knob. In its first aspect, the handle knob includes a spindle having an outer periphery and fixed to a handle arm, a bearing provided on the outer periphery, a cylindrical member rotatably provided on the spindle via the bearing, an insertion hole through which the cylindrical member is inserted from one end and which is open at the other end, a handle knob having a fixed end fixed to one end of the cylindrical member so as to rotate integrally with the cylindrical member inserted in the insertion hole, and an open end supported on the other end of the cylindrical member, and a waterproof plug that waterproofs the open end, the waterproof plug comprising an insertion portion that is inserted from the insertion hole toward the open end, and a waterproof portion that is disposed on the outer periphery of the insertion portion and abuts against the inner periphery of the insertion hole.

[0008] This waterproof plug is inserted into an insertion hole in a handle knob through which a cylindrical member, on which a support shaft is rotatably mounted, is inserted toward the open end of the cylindrical member. The waterproof plug comprises an insertion portion and a waterproof portion. The insertion portion can be securely inserted into the insertion hole, and the waterproof portion is located on the outer periphery of the insertion portion and abuts against the inner periphery of the insertion hole, sealing the insertion hole. This waterproof portion prevents seawater from entering the insertion hole from the outside, thereby preventing malfunction of the handle knob due to tidal buildup caused by the adhesion of tidal components contained in seawater inside the support shaft of the handle arm inserted into the cylindrical member of the handle knob. The insertion portion and waterproof portion that make up the waterproof plug can be either separate or integrated. Integrating the insertion portion and waterproof portion allows for a simpler structure, thereby ensuring waterproofness while reducing costs.

[0009] In a second aspect of the present invention, in the first configuration, the waterproof portion can be configured to have a strip-shaped protrusion formed around the periphery of the insertion portion on the leading insertion side.

[0010] In the configuration of the second aspect of the present invention, the waterproof portion is formed as a strip-shaped protrusion on the leading insertion side, and by providing the strip-shaped protrusion on the leading insertion side, it is possible to prevent a gap from occurring between the waterproof portion and the cylindrical member. According to the configuration of the second aspect of the present invention, since an O-ring is not provided, there is no risk of deterioration of the sealing portion over time. In addition, the number of parts is small and the configuration is simple, which improves productivity and reduces costs.

[0011] A third aspect of the present invention is the first or second aspect, wherein the waterproof portion has a tapered portion whose diameter increases from the rear end side of the insertion portion toward the front end side of the insertion portion.

[0012] In the configuration of the third aspect of the present invention, by making the waterproof section a tapered section that expands in diameter from the insertion section toward the leading end of the insertion of the cylindrical member, the range of elastic diameter reduction is widened, and the pressing force at which it abuts against the inner periphery of the cylindrical member can be increased, particularly at the leading end of the insertion. With this configuration, by elastically deforming the tapered waterproof section, it abuts on the inner periphery of the cylindrical member at a surface, thereby reliably maintaining the waterproof state.

[0013] In a fourth aspect of the present invention, in any of the first to third aspects, the waterproof plug can be configured to have a flange body provided at the rear end of the insertion portion and having an outer diameter larger than the outer diameter of the waterproof portion.

[0014] In the configuration of the fourth aspect of the present invention, a flange body is provided to seal the opening on the other end of the cylindrical member where seawater is expected to seep in, so that the flange body extends to the periphery of the opening and abuts to cover the opening, thereby sealing the path for seawater to seep in. According to this configuration, the provision of this flange body, together with the waterproof portion, can achieve reliable waterproofing.

[0015] A fifth aspect of the present invention is any one of the first to fourth aspects, further comprising a cover member that is attached to the handle knob and holds and covers the inserted rear end side of the waterproof plug.

[0016] In the configuration of the fifth aspect of the present invention, a cover member is provided that presses against and covers the waterproof plug and flange body, preventing seawater from coming into direct contact with the waterproof plug and flange body and lengthening the path through which seawater can penetrate, thereby maintaining the waterproof function of the waterproof plug for a long period of time. The cover member can also be used as a nameplate.

[0017] A sixth aspect of the present invention may be configured such that in any one of the first to fifth aspects, the waterproof part is a separate cap that covers the leading end of the insertion part.

[0018] In the configuration of the sixth aspect of the present invention, by using a waterproof portion that covers the leading insertion side of the insertion portion with a separate cap, it is possible to arbitrarily select an elastic material suitable for waterproofing. For example, if the insertion portion is molded from resin, there is a possibility that a part line may occur around the periphery. However, by using a separate cap as the waterproof portion, this part line abuts against the inner periphery of the cylindrical member, creating a gap and eliminating the risk of water seepage. Furthermore, by using a separate cap on the leading insertion side of the insertion portion made of a resin that is more rigid than the resin of the insertion portion, the position when inserted into the insertion hole is more stable, there is no risk of gaps occurring, and waterproofing is improved. [Effects of the Invention]

[0019] The present invention solves the problems of the prior art as described above, and can provide a fishing reel handle knob that can prevent seawater from entering the handle knob. [Brief explanation of the drawings]

[Figure 6] FIG. 10 is a partially enlarged cross-sectional view showing part A (FIG. 2) of the handle knob according to the fourth embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0021] (Description of the First Embodiment) A first embodiment of a fishing reel handle knob according to the present invention will be described below with reference to Figs. 1 to 3. Fig. 1 is a side view showing the overall configuration of a fishing reel according to the first embodiment of the present invention. Fig. 2 is a side sectional view of the handle knob shown in Fig. 1. Fig. 3 is a partially enlarged sectional view showing part A (Fig. 2) of the handle knob shown in Fig. 2.

[0022] Although the following describes an embodiment of a spinning reel for fishing, it goes without saying that the present invention can also be applied to other types of reels that use similar handle knobs (for example, double-bearing reels, electric reels, etc.). For convenience, as shown in FIG. 1, the direction in which the fishing line is released (toward the tip of the fishing rod, not shown) will be referred to as the "front" and the side of the reel leg (attachment leg) attached to the fishing rod, not shown, will be referred to as the "up" in the following description.

[0023] <Overall structure of a fishing reel> The fishing reel 1 according to this embodiment is a spinning reel, and when the handle 2 is rotated, a bobbin-like part called the spool 4 moves back and forth, while the rotor 3 rotates around the spool 4, winding the fishing line 40 onto the spool 4. 1 shows a fishing reel 1 attached to a fishing rod (not shown), and for convenience in the following description, the direction in which the fishing line is let out (toward the tip of the fishing rod (not shown)) may be referred to as "front" and the side of the leg 50 attached to the fishing rod (not shown) may be referred to as "up." Furthermore, although the handle 2 and spool 4 (described below) rotate, they may be described in the stationary state shown in FIG. 1.

[0024] Referring to FIG. 1, a fishing reel 1 comprises a reel body 10, legs 50 integrated with the reel body 10, a rotating rotor 3, and a spool 4 supported on the front side of the reel body 10 so as to be movable back and forth, which moves back and forth in synchronization with the rotation of the rotor 3 and on which fishing line 40 is wound.

[0025] Rotation of the rotor 3 (about the front-to-rear axis) and back-to-back movement of the spool 4 are actuated by rotating (about the left-to-right axis) the handle 2, which is rotatably supported on the reel body 10, to reel in the fishing line 40. Depending on the user's dominant hand, the handle 2 can be attached to the front (left side) or back (right side) of Figure 1, with the handle shaft 22 as a support shaft.

[0026] The handle 2 includes a handle knob 20 and a handle arm 21 to the tip of which the handle knob 20 is rotatably attached. The handle arm 21 is attached to the base end of a handle shaft 22.

[0027] The reel unit 10 includes a reel body 11 having an internal space and a body guard 12 that protects the rear of the reel body 11.

[0028] The reel body 11 is integrally provided with a leg 50 extending toward (upper side of) the fishing rod (not shown) and a T-shaped rod attachment portion 51 extending forward and backward from the upper end of the leg 51. The upper side of the rod attachment portion 51 is recessed along the curvature of the fishing rod's outer periphery, and this recessed portion abuts against the fishing rod to attach the fishing reel 1 to the fishing rod. Mechanisms that perform reel functions such as rotational drive and transmission are housed within the reel body 11. Furthermore, the spool shaft (not shown) of the spool 4 passes through the reel body 11, and supports the spool shaft, which extends in the forward and backward directions in FIG. 1, so that the spool shaft can move back and forth in the forward and backward directions.

[0029] The body guard 12 covers the rear of the reel body 11 and is fixed to the reel body 11 with screws or the like. The handle shaft 22 is supported by a support formed on the reel body 11 via a bearing for smooth rotation.

[0030] The spool 4 has a fishing line 40 wound around the outer periphery of a bobbin trunk 41. A rotor 3 is disposed around the spool 4, and a pair of rotor arms 35, 35 extend forward from the rotor 3. Bail arms 32, 32 are swingably disposed at the front ends of the rotor arms 35, 35. The bail arms 32, 32 are connected to both ends of a bail 31. A fishing line guide (line roller) 36 that guides the fishing line 40 to the spool 4 is provided on one side of the bail arms 32, 32.

[0031] The bail arms 32, 32 together with the bail 31 are arranged to be swingable relative to the rotor arms 35, 35 between a winding position in which the fishing line 40 can be wound onto the spool 4 and a releasing position in which the fishing line 40 can be released from the spool 4.

[0032] In Figure 1, the bail arms 32, 32 are shown in a winding position in which the fishing line 40 can be wound onto the spool 4. When the user rotates the handle 2 in this position, the bail arm 32 rotates around the spool 4 due to a mechanism that performs reel functions such as rotational drive and transmission, which is disposed within the reel body 11, and the fishing line 40 is wound onto the bobbin trunk 41 of the spool 4 through a fishing line guide section (line roller) 36 disposed on one of the bail arms 32, 32.

[0033] At this time, as described above, the spool 4 moves back and forth relative to the reel body 10, so that the fishing line 40 is wound evenly onto the bobbin trunk 41 of the spool 4.

[0034] <Handle knob configuration> Next, the configuration of the handle knob 20 will be described in more detail with reference to the drawings. As shown in Fig. 2, the handle knob 20 includes a spindle 23 fixed to a handle arm 21, a pair of bearings 24, 26 provided to abut the outer periphery of the spindle 23, and a handle knob 100 provided rotatably with respect to the spindle 23 via the bearings 24, 26.

[0035] The handle knob 100 is available in a variety of outer shapes, such as I-shaped, T-shaped, and round, to suit the fishing specifications, target fish, and angler preferences, and the material of the outer portion that the angler grips can be selected from rubber, metal, carbon, cork, and other materials. The internal structure of the handle knob 100 itself is designed and manufactured according to the outer shape and material. In this embodiment, a round-shaped handle knob 100 will be described as an example, and its internal structure will also be described in a simplified manner. The waterproof plug 120 described below can be applied to the handle knob 100 regardless of the outer shape and material.

[0036] The handle knob 100 in this embodiment has an oval outer shape that is long in the front-to-rear direction and short in the up-down direction in Fig. 1. As shown in Fig. 2, the interior of the handle knob 100 is formed by combining a first knob outer casing 102 that covers the bearing 26 side and a second knob outer casing 104 that covers the bearing 24 side. The first knob outer casing 102 and the second knob outer casing 104 house a first knob main body 106 and a second knob main body 108, respectively.

[0037] An insertion hole 110 is formed in the second knob outer casing 104, second knob main body 108, and first knob main body 106 of the handle knob 100, and passes from the handle arm 21 side to the left along the spindle 23. The insertion hole 110 is a through-hole into which a cylindrical member 112 is inserted from one end and is open at the other end. The cylindrical member 112, which is supported rotatably on the spindle 23, is inserted from an insertion opening 117 on the handle arm 21 side of the insertion hole 110.

[0038] The cylindrical member 112 is rotatable about the support shaft 23 via the bearings 24 and 26. That is, the user (angler) grips the handle knob 20 and rotates the handle arm 21 around the handle shaft 22, thereby smoothly reeling in the fishing line 40. For this reason, the cylindrical member 112 and the support shaft 23 are rotatably supported by the bearings 26 and 28, and it is necessary to reliably prevent seawater from entering the gap between the cylindrical member 112 and the support shaft 23, as tidal components contained in the seawater may cause the bearings 26 and 28 to stick, resulting in so-called tidal jamming, which would interfere with the rotation of the reel.

[0039] A fixed end 114 for fixing the cylindrical member 112 inside the handle knob 100 is formed at the end of the insertion hole 110 inside the second knob outer casing 104 on the bearing 24 side, and an open end 116 for supporting the cylindrical member 112 is also formed at the end of the bearing 26 of the insertion hole 110 inside the second knob outer casing 104. In this way, the cylindrical member 112 is integrated with the handle knob 100 and can rotate.

[0040] The bearing 26 is pressed against the open end 116 in the axial direction, restricting the movement of the support shaft 23 to the left. Furthermore, a female screw 28 is formed in the center of the end face of the support shaft 23 on the bearing 26 side, and by threading the male screw 30 into the female screw 28, the movement of the support shaft 23 to the right is restricted. In this way, the position of the support shaft 23 relative to the handle knob 100 is fixed left and right while remaining rotatable.

[0041] The handle knob 100 further includes a waterproof plug 120 that waterproofs the open end 116. For a detailed structure, referring also to Figure 3, which is a partially enlarged cross-sectional view of part A in Figure 2, the waterproof plug 120 is formed from an insertion portion 122 that is inserted from an opening 118 formed in the first knob body 106 on the left side of the insertion hole 110 toward the open end 116, and a waterproof portion 124 that is disposed on the outer periphery of the insertion portion 122 and has a strip-shaped protrusion that abuts against the inner periphery of the insertion hole 110.

[0042] Waterproof plug 120 is in the shape of a cap with a bottomed hole 128 formed therein, and is structured so that the diameter of waterproof plug 120 can be easily reduced in the direction of the tip of insertion when inserted into insertion hole 110. There are no particular restrictions on the material of waterproof plug 120, but either a plastic or elastic material can be used for insertion portion 122, and it is preferable that the material be one that can maintain its shape even after insertion into insertion hole 110, while it is preferable that waterproof portion 124 be made of a material that can deform at least more elastically than insertion portion 122. Note that insertion portion 122 and waterproof portion 124, which make up waterproof plug 120, can be used either as separate bodies or as an integrated body.

[0043] When the waterproof plug 120 is inserted into the insertion hole 110, the waterproof part 124 is pushed in while abutting against the inner periphery of the insertion hole 110 so as to rub against the inner periphery. At this time, although it depends on the sealing condition of the insertion hole 110, the air pressure inside the insertion hole 110 becomes higher than the outside, which improves the effectiveness of preventing seawater from entering.

[0044] This waterproof portion 124 abuts against the inner periphery of the insertion hole 110 to seal the insertion hole 110 and prevent seawater from entering the insertion hole 110 from the outside, thereby making it possible to avoid malfunction of the handle knob 100 due to tidal buildup caused by components of tide, etc. contained in seawater, adhering around the support shaft 23 of the handle arm 21 inserted into the cylindrical member 112 of the handle knob 100. Needless to say, the insertion hole 110 can be sealed even in a configuration that does not have a bottomed hole 128.

[0045] To further improve the waterproof function of the waterproof plug 120, after the waterproof plug 120 is inserted into the insertion hole 110, a cover member 130 can be attached to hold and cover the rear end 123 of the insertion portion of the waterproof plug 120. The cover member 130 may be attached by screwing with a cover member set screw 132, or by using an adhesive or the like. A sealant may also be interposed between the cover member 130 and the waterproof plug 120.

[0046] The cover member 130 can also be used as a nameplate. Generally, a "nameplate" is made of metal, plastic, or other material and displays necessary information in a manner that will not easily fade. In this embodiment, however, the cover member 130 displays necessary information as a regular nameplate and also holds the waterproof plug 120, thereby preventing the waterproof function from deteriorating. In other words, by covering and pressing the waterproof plug 120, seawater is not directly sprayed on the waterproof plug 120 and the path for seawater to penetrate is lengthened, so the waterproof function of the waterproof plug 120 can be maintained for a long period of time.

[0047] In this embodiment, the cover member 130 that is attached to the handle knob 110 and holds and covers the rear end of the waterproof plug 120 after insertion is described as also serving as a nameplate, but another member such as a lid may be used instead of the nameplate.

[0048] (Description of the second embodiment) Next, a second embodiment of the present invention will be described with reference to Fig. 4. Fig. 4 is a partially enlarged cross-sectional view showing part A (see Fig. 2) of the handle knob according to the second embodiment. In the following explanation, explanations of the same configuration as in the first embodiment will be omitted, and only the different configurations will be described.

[0049] 4, the waterproof plug 220 according to the second embodiment is formed with a tapered section 226 that increases in diameter from the rear end of insertion of the insertion section 222 toward the front end of insertion (from left to right in FIG. 4), and this tapered section 226 constitutes a waterproof section 224 that abuts against the inner periphery of the insertion hole 110. Like the first embodiment, this waterproof plug 220 is also in the shape of a cap with a bottomed hole 228 formed therein.

[0050] The waterproof plug 220 has a waterproof section 224 with a tapered section 226, so that when the waterproof plug 220 is inserted, even if the waterproof plug 220 is slightly tilted relative to the axis of the insertion hole 110, the waterproof plug 220 can reliably abut against the inner periphery of the insertion hole 110, thereby achieving a tightly sealed state. Furthermore, by providing a bottomed hole 228, the elastic displacement of the waterproof plug 220 can be effectively utilized during insertion, achieving a reliable inserted state.

[0051] In the second embodiment, as in the first embodiment, the waterproof plug 220 is covered and pressed with the cover member 130, so that seawater does not come into direct contact with the waterproof plug 220 and the path through which seawater can penetrate can be lengthened, thereby maintaining the waterproof function of the waterproof plug 220 for a long period of time.

[0052] (Description of the third embodiment) Next, a third embodiment of the present invention will be described with reference to Fig. 5. Fig. 5 is a partially enlarged cross-sectional view showing part A (see Fig. 2) of the handle knob according to the third embodiment. In the following description, explanations of configurations similar to those of the first and second embodiments will be omitted, and only configurations that differ will be described.

[0053] 5, the waterproof plug 320 according to the third embodiment is provided with a flange body 326 that is provided on the rear insertion end side of the insertion portion 322 and has an outer diameter larger than that of the waterproof portion 324. The flange body 326 extends to the periphery of the opening 118 and abuts against the first knob body 106 so as to cover the opening 118. Also in the third embodiment, the waterproof plug 320 is inserted into the insertion hole 110, a bottomed hole 328 is formed in the waterproof plug 320, and the cover member 130 covers and presses the waterproof plug 320.

[0054] The flange body 326 may be molded integrally as part of the waterproof plug 320, or may be a separate body that is adhered, fixed, or attached to the waterproof plugs 120 and 220 of the first and second embodiments.

[0055] In this way, by providing flange body 326 and sealing opening 118 through which seawater is expected to infiltrate beyond bearing 26 at the other end of cylindrical member 112, it is possible to restrict the path of seawater infiltration, and by providing this flange body 326, in combination with waterproof section 324, reliable waterproofing can be achieved.

[0056] (Description of the Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to Fig. 6. Fig. 6 is a partially enlarged cross-sectional view showing part A (see Fig. 2) of the handle knob according to the fourth embodiment. In the following explanation, explanations of configurations similar to those of the first, second, and third embodiments will be omitted, and only configurations that differ will be described.

[0057] Referring to Figure 6, the waterproof plug 420 of the fourth embodiment has a configuration similar to that of the first, second and third embodiments, and includes an insertion portion 422 that is inserted into the insertion hole 110, a waterproof portion 424 that abuts against the inner periphery of the insertion hole 110, a flange body 426 that seals the opening 118, and a cover member 130 that covers and presses against the waterproof plug 420.

[0058] However, in the first, second and third embodiments, the waterproof plug 420 could be applied as an integrated or separate part, but in this embodiment, it has a separate cap-shaped waterproof part 424 fitted into a fitting part 428 formed on the insertion tip side of the insertion part 422.

[0059] With this configuration, the insertion portion 422 and the waterproof portion 424 are separate bodies, and different materials can be used. For example, if the insertion portion 422 is made of resin, there is a possibility that a parting line will occur around it, but by making the waterproof portion 424 a separate cap, this parting line will come into contact with the inner periphery of the cylindrical member 112, creating a gap and eliminating the risk of water seepage.

[0060] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can be modified and used within the scope of the invention. [Explanation of symbols]
