Description

[Technical Field]

[0001] The present invention relates to a dual-bearing reel spool and a dual-bearing reel. [Background technology]

[0002] The spool of a dual-bearing reel has a bobbin trunk and a pair of flanges. Fishing line is wound around the outer periphery of the bobbin trunk. The pair of flanges are located on both ends of the bobbin trunk. The outer periphery of the bobbin trunk of the spool disclosed in Patent Document 1 is slightly inclined with respect to the spool's rotation axis so that the diameter expands toward the pair of flanges.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-127378 Summary of the Invention [Problem to be solved by the invention]

[0004] In dual-bearing reels, improving the static balance of the spool when fishing line is wound around it improves the rotation feel during casting. To improve the static balance of the spool, it is preferable that the first layer of fishing line, which is wound around the bobbin trunk first, does not shift when the second layer of fishing line is wound around the bobbin trunk. With conventional dual-bearing reel spools, there is a risk that the first layer of fishing line will shift when the second layer of fishing line is wound around the bobbin trunk, leaving room for improvement.

[0005] An object of the present invention is to provide a spool and a dual-bearing reel that can improve the rotation feeling during casting. [Means for solving the problem]

[0006] According to a first aspect of the present invention, a spool for a dual-bearing reel includes a bobbin trunk, a wall, and a pair of flanges. The bobbin trunk has an outer circumferential surface around which fishing line is wound and at least one through-hole that penetrates the outer circumferential surface in the radial direction of the spool's rotational axis. The wall extends from the inner circumferential surface of the bobbin trunk toward the rotational axis and is positioned so as not to overlap with the at least one through-hole when viewed radially. The pair of flanges extend from both ends of the bobbin trunk in a direction away from the rotational axis. The outer circumferential surface of the bobbin trunk has a tapered surface that slopes toward the pair of flanges and approaches the rotational axis.

[0007] In the dual-bearing reel spool according to the first aspect, the outer peripheral surface of the bobbin trunk has a tapered surface that slopes toward the pair of flanges and approaches the rotation axis. This prevents the first layer of fishing line, which is wound first around the bobbin trunk, from shifting when the second layer of fishing line is wound around the bobbin trunk. This improves the static balance of the spool when the fishing line is wound around it, thereby improving the rotation feel during casting. Furthermore, because at least one through-hole and the wall do not overlap when viewed radially, a knot for securing the fishing line to the spool can be easily placed in the through-hole. This prevents the fishing line knot from protruding from the outer peripheral surface of the bobbin trunk, allowing the fishing line to be wound around the spool according to the winding lead. As a result, the static balance of the spool when the fishing line is wound around it is improved, thereby improving the rotation feel during casting.

[0008] With respect to a second aspect of the present invention, in the dual-bearing reel spool according to the first aspect, at least one through-hole in the bobbin trunk has a first through-hole located in the axial center of the rotational axis of the bobbin trunk and a second through-hole located adjacent to the first through-hole in the circumferential direction of the rotational axis. In the dual-bearing reel spool according to the second aspect, the fishing line can be easily secured to the spool by passing the fishing line through the first through-hole and the second through-hole. Furthermore, the fishing line can be started to be wound onto the spool from the axial center of the rotational axis of the bobbin trunk.

[0009] With regard to the third aspect of the present invention, in the dual-bearing reel spool according to the first aspect, at least one through-hole and wall of the bobbin trunk is positioned off-center in the axial direction of the rotation axis of the bobbin trunk. In the dual-bearing reel spool according to the third aspect, it is possible to prevent the wall thickness near the center of the bobbin trunk from increasing, thereby achieving low inertia of the spool.

[0010] With regard to a fourth aspect of the present invention, in the dual-bearing reel spool according to the first aspect, the pair of flanges includes a first flange and a second flange positioned axially opposite the first flange, the bobbin trunk further includes an annular rib protruding from the inner peripheral surface of the bobbin trunk toward the rotational axis, the wall is positioned between the axial center of the rotational axis of the bobbin trunk and the first flange, and the rib is positioned between the axial center of the rotational axis of the bobbin trunk and the second flange. The dual-bearing reel spool according to the fourth aspect can increase the rigidity of the spool.

[0011] With respect to the fifth aspect of the present invention, in the dual-bearing reel spool according to the fourth aspect, at least one through-hole is disposed between the wall portion and the first flange portion. In the dual-bearing reel spool according to the fifth aspect, the static balance of the spool can be improved when fishing line is wound around it, and the inertia of the spool can be reduced.

[0012] With respect to a sixth aspect of the present invention, in the dual-bearing reel spool according to any one of the first to fifth aspects, the wall portion overlaps with the tapered surface when viewed from the radial direction. In the dual-bearing reel spool according to the sixth aspect, the static balance of the spool can be improved when fishing line is wound around it.

[0013] With regard to a seventh aspect of the present invention, in a dual-bearing reel spool according to any one of the first to sixth aspects, the outer peripheral surface of the bobbin trunk is located at the axial center of the rotational axis of the bobbin trunk and further has a flat surface extending along the axial direction of the rotational axis, with the tapered surface located adjacent to the flat surface. The dual-bearing reel spool according to the seventh aspect can improve the static balance of the spool when fishing line is wound around it.

[0014] With regard to an eighth aspect of the present invention, in the dual-bearing reel spool according to any one of the first to seventh aspects, at least one through-hole has an elliptical shape that is longer in the circumferential direction of the rotation axis than in the axial direction of the rotation axis. The dual-bearing reel spool according to the seventh aspect can improve the static balance of the spool when fishing line is wound around it.

[0015] According to a ninth aspect of the present invention, a dual-bearing reel includes a spool according to any one of the first to eighth aspects and a level wind mechanism for winding fishing line evenly around the spool. With the dual-bearing reel according to the ninth aspect, the static balance of the spool can be improved when fishing line is wound around the spool, thereby improving the rotation feel when casting.

[0016] With respect to a tenth aspect of the present invention, in the dual-bearing reel according to the ninth aspect, the level wind mechanism has a line guide that guides the fishing line, the line guide having an opening through which the fishing line passes, and the opening of the line guide having an upper edge that tapers from bottom to top. In the dual-bearing reel according to the tenth aspect, when the fishing line is wound onto the spool via the level wind mechanism, the fishing line is easily guided at a single point at the upper edge, making it possible to wind the fishing line onto the spool according to the line winding lead. This improves the static balance of the spool when the fishing line is wound onto the spool.

[0017] In the dual-bearing reel of the tenth aspect, the opening further has a lower edge that is positioned below the upper edge and protrudes forward from the upper edge. The dual-bearing reel of the eleventh aspect can prevent the fishing line from interfering with the level wind guard positioned in front of the level wind mechanism during casting. [Effects of the Invention]

[0020] 1 is a perspective view of a dual-bearing reel 1 equipped with a spool according to one embodiment of the present invention, and FIG. 2 is a front view of the dual-bearing reel 1.

[0021] As shown in Figures 1 and 2, dual-bearing reel 1 comprises a reel body 2, a handle 3, and a spool 4. Dual-bearing reel 1 also comprises various mechanisms (not shown), such as a rotation transmission mechanism that transmits the rotation of the handle 3 to the spool 4, a clutch mechanism, a casting control mechanism, a spool braking mechanism, and a drag mechanism.

[0022] In the following description, the direction in which the fishing line is let out when fishing is referred to as the front, and the opposite direction as the rear. Furthermore, left and right refer to the left and right when viewing the dual-bearing reel 1 from the rear. Furthermore, the direction in which the rotation axis X of the spool 4 extends is referred to as the axial direction, the direction perpendicular to the rotation axis X is referred to as the radial direction, and the direction around the rotation axis X is referred to as the circumferential direction.

[0023] The reel body 2 has a frame 6, a right cover 7 that covers the right side of the frame 6, and a left cover 8 that covers the left side of the frame 6. The frame 6 has a first side plate 6a, a second side plate 6b that is arranged axially spaced apart from the first side plate 6a, and a plurality of connecting portions 6c that connect the first side plate 6a and the second side plate 6b.

[0024] The handle 3 is rotatably attached to the side of the reel body 2. In this embodiment, the handle 3 is attached to the right side of the reel body 2.

[0025] The spool 4 is rotatably supported on the reel body 2 between the first side plate 6a and the second side plate 6b. The spool 4 is fixed to a spool shaft 10 (see FIG. 4) that is rotatably supported on the reel body 2, and is rotatably supported on the reel body 2 via the spool shaft 10. In this embodiment, the rotational axis X of the spool 4 coincides with the axis of the spool shaft 10.

[0026] Fig. 3 is a rear view of the spool 4. Fig. 4 is a cross-sectional view of the spool 4. As shown in Figs. 2 and 3, the spool 4 has a bobbin trunk 21, a pair of flanges 22, a shaft mounting portion 23, a wall 24, and a rib 26.

[0027] The bobbin trunk 21 is generally cylindrical. The bobbin trunk 21 extends in the axial direction. The bobbin trunk 21 has an outer peripheral surface 31 around which the fishing line is wound, and at least one through-hole 32. The outer peripheral surface 31 has a flat surface 34 and a tapered surface 35. The flat surface 34 is located at the axial center C of the bobbin trunk 21. The flat surface 34 extends along the axial direction.

[0028] The tapered surface 35 is inclined in a direction approaching the rotation axis X toward the pair of flange portions 22. The tapered surface 35 is inclined so that the distance to the rotation axis X gradually decreases as it approaches the axial center C of the bobbin trunk 21. The taper angle of the tapered surface 35 with respect to the rotation axis X is preferably within a range of 0.1° to 3°, and more preferably 1 to 2°.

[0029] The tapered surface 35 is disposed adjacent to the flat surface 34. The tapered surface 35 has a first tapered surface 35a and a second tapered surface 35b. The first tapered surface 35a is disposed to the right of the axial center C of the bobbin trunk 21. The first tapered surface 35a is connected to the right end of the flat surface 34. The second tapered surface 35b is disposed to the left of the axial center C of the bobbin trunk 21. The second tapered surface 35b is connected to the left end of the flat surface 34. The second tapered surface 35b has a shape symmetrical to the first tapered surface 35a.

[0030] At least one through-hole 32 is disposed on the outer peripheral surface 31 and penetrates radially from the outer peripheral surface 31 to the inner peripheral surface 33 of the bobbin trunk 21. The at least one through-hole 32 is disposed at the axial center C of the bobbin trunk 21. When viewed radially, the at least one through-hole 32 overlaps with the flat surface 34. The at least one through-hole 32 has an elliptical shape that is longer in the circumferential direction than in the axial direction.

[0031] In this embodiment, the at least one through hole 32 has a plurality of through holes including a first through hole 32a and a second through hole 32b. In this embodiment, six through holes 32 are formed in the bobbin trunk 21. The first through hole 32a and the second through hole 32b are arranged adjacent to each other in the circumferential direction. It is desirable that the through holes 32 be arranged evenly in the circumferential direction.

[0032] The pair of flanges 22 are generally disk-shaped. The pair of flanges 22 extend from both ends of the bobbin trunk 21 in a direction away from the rotation axis X. The pair of flanges 22 extend radially outward from both ends of the bobbin trunk 21. The pair of flanges 22 are inclined so as to widen axially outward as they extend radially outward.

[0033] The pair of flange portions 22 has a first flange portion 22a and a second flange portion 22b. In this embodiment, the first flange portion 22a is disposed at a position closer to the handle 3 in the axial direction than the second flange portion 22b. The first flange portion 22a extends radially outward from the right end of the first tapered surface 35a. The second flange portion 22b is disposed opposite the first flange portion 22a in the axial direction. The second flange portion 22b is farther from the handle 3 in the axial direction than the first flange portion 22a. The second flange portion 22b extends radially outward from the left end of the second tapered surface 35b.

[0034] The shaft mounting portion 23 is disposed on the inner periphery of the bobbin trunk 21. The shaft mounting portion 23 is formed in a cylindrical shape. The shaft mounting portion 23 has a through-hole 23a that penetrates in the axial direction. The spool shaft 10 is press-fitted and fixed into the through-hole 23a.

[0035] The wall portion 24 connects the bobbin trunk 21 and the shank attachment portion 23. The wall portion 24 is generally disk-shaped. The wall portion 24 extends in the radial direction. The wall portion 24 extends from the inner circumferential surface 33 of the bobbin trunk 21 toward the rotation axis X. The wall portion 24 extends from the outer circumferential surface of the shank attachment portion 23 toward the inner circumferential surface 33 of the bobbin trunk 21. As shown in FIG. 4 , the wall portion 24 has a plurality of through holes 24a that penetrate in the axial direction. The multiple through holes 24a are arranged at intervals from one another in the circumferential direction.

[0036] The wall portion 24 is disposed in a position that does not overlap at least one of the through holes 32 when viewed from the radial direction. The wall portion 24 is disposed in a position offset from the axial center C of the bobbin trunk 21. The wall portion 24 is disposed in a position biased toward the handle 3 with respect to the axial center C of the bobbin trunk 21. The wall portion 24 is disposed between the axial center C of the bobbin trunk 21 and the first flange portion 22a, and is disposed in a position closer to the first flange portion 22a than the second flange portion 22b in the axial direction. The wall portion 24 overlaps with the first tapered surface 35a of the tapered surface 35 when viewed from the radial direction.

[0037] The rib 26 is an annular rib that protrudes from the inner circumferential surface 33 of the bobbin trunk 21 toward the rotation axis X. The rib 26 is located between the axial center C of the bobbin trunk 21 and the second flange portion 22b. When viewed from the radial direction, the rib 26 overlaps with the second tapered surface 35b of the tapered surface 35. The rib 26 is located on the inner circumferential surface 33 of the bobbin trunk 21 close to the second flange portion 22b. When viewed from the radial direction, the rib 26 does not overlap with the shaft attachment portion 23.

[0038] As shown in Figures 2 and 5, the dual-bearing reel 1 is equipped with a level wind mechanism 40 for evenly winding the fishing line around the spool 4. The level wind mechanism 40 includes a worm shaft 41, a guide member 42, a sliding member 43, and a fishing line guide 44. The worm shaft 41 extends in the axial direction. The worm shaft 41 is rotatably supported by the reel body 2. A spiral groove is formed on the outer circumferential surface of the worm shaft 41. The guide member 42 is a member for guiding the sliding member 43. The guide member 42 is formed in a cylindrical shape. The guide member 42 is disposed radially outward of the worm shaft 41. The sliding member 43 has an engaging member 43a that meshes with the spiral groove of the worm shaft 41. When the worm shaft 41 rotates in response to rotation of the handle 3, the sliding member 43 reciprocates in the axial direction along the guide member 42.

[0039] The fishing line guide 44 is disposed on the sliding member 43. The fishing line guide 44 is fixed to the sliding member 43 so as to be movable integrally with the sliding member 43. The fishing line guide 44 is fixed to a fixing hole 43b of the sliding member 43. The fishing line guide 44 may be integral with the sliding member 43. The fishing line guide 44 extends in the front-to-rear direction. The upper part of the fishing line guide 44 is inclined upward toward the rear. The lower part of the fishing line guide 44 extends in a substantially horizontal direction.

[0040] 5 and 6, the fishing line guide 44 has an opening 46 through which the fishing line is passed. The opening 46 is open toward the front. The opening 46 is formed to penetrate the fishing line guide 44 in the front-to-rear direction.

[0041] The opening 46 has an upper edge 46a and a lower edge 46b. The upper edge 46a has a shape that tapers upward. The upper edge 46a is formed so that its axial dimension gradually decreases upward. The upper end of the upper edge 46a is formed in an arc shape. The upper edge 46a is configured to make point contact with the fishing line when the fishing line is wound onto the spool 4. When the fishing line is wound onto the spool 4, the fishing line is guided at a point by the upper edge 46a. The lower edge 46b is positioned lower than the upper edge 46a. The lower edge 46b protrudes forward more than the upper edge 46a.

[0042] As shown in Figure 2, the lower edge 46b of the opening 46 is located above the level wind guard 9 disposed on the reel body 2. The level wind guard 9 is located in front of the sliding member 43. The axial distance from the lower edge 46b of the opening 46 to the level wind guard is smaller than the axial distance from the upper edge 46a of the opening 46 to the level wind guard. In other words, the lower edge 46b of the opening 46 is located axially closer to the level wind guard than the upper edge 46a of the opening 46.

[0043] In the dual-bearing reel 1 described above, the outer peripheral surface 31 of the bobbin trunk 21 of the spool 4 has a tapered surface 35 that slopes toward the rotation axis X as it approaches the pair of flanges 22, thereby preventing the first layer of fishing line that is wound first around the bobbin trunk 21 from shifting when the second layer of fishing line is wound around the bobbin trunk 21. This improves the static balance of the spool 4 when fishing line is wound around it, thereby improving the rotation feel when casting.

[0044] Furthermore, because at least one through-hole 32 and the wall portion 24 do not overlap when viewed from the radial direction, a knot for securing the fishing line to the spool 4 can be easily placed in at least one through-hole 32. This prevents the knot of the fishing line from protruding from the outer peripheral surface 31 of the bobbin trunk 21, making it possible to wind the fishing line onto the spool 4 according to the winding lead. As a result, the static balance of the spool 4 can be improved when the fishing line is wound onto the spool 4, improving the rotation feel during casting.

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

[0046] 7 is a cross-sectional view of a spool 104 according to another embodiment of the present invention. Regarding the spool 104, configurations that differ from the above embodiment will be described, and descriptions of configurations that are substantially the same as the above embodiment will be omitted.

[0047] At least one through-hole 132 in the bobbin trunk 121 of the spool 104 is positioned at a position offset from the axial center C of the bobbin trunk 121. The at least one through-hole 132 is positioned between the wall 124 and the first flange 22a. The wall 124 is positioned more biased toward the handle 3 with respect to the axial center C of the bobbin trunk 121 than in the previous embodiment. The distance from the wall 124 to the flat surface 134 in the axial direction is greater than the distance from the rib 126 to the flat surface 134.

[0048] The rib 126 overlaps with the flat surface 134 when viewed from the radial direction. The rib 126 overlaps with the shaft mounting portion 123 when viewed from the radial direction. The axial distance from the rib 126 to the wall portion 124 is smaller than the axial dimensions of the first tapered surface 135a and the second tapered surface 135b. The thickness of the flat surface 134 is thinner than the thickness of the flat surface 34 according to the previous embodiment. The thickness of the flat surface 134 is thinner than the thickness of at least a portion of the first tapered surface 135a.

[0049] In a dual-bearing reel in which the handle 3 is disposed on the left side of the reel body 2, the configuration of the spool 4, 104 may be adopted.

[0050] In the above embodiment, the flange portion located at the left end of the bobbin trunk 21 may be the first flange portion 22a, and the flange portion located at the right end of the bobbin trunk 21 may be the second flange portion 22b. [Explanation of symbols]
