Description

The present invention relates to a spinning reel.It is known that at the dead points of conventional spinning reels, various problems occur as the spool reciprocates, i.e., at the foremost and rearmost positions of the spool. For example, when the fishing line is released or ejected, noises are generated and the draw-off resistance of the fishing line is increased at the dead points by the contact between the fishing lines. This results in a reduction in flight distance. In order to solve these problems at the dead points, a conventional apparatus having an increased bobbin diameter and a bobbin having an extended swing stroke has been proposed. For example, JP 2019 106 898 A describes such a device. In addition, an apparatus having a technology that makes the winding pitch of the fishing line finer has been proposed. For example, JP H11-086 A discloses such a device.It has been found that in the conventional devices, the diameter of the rotor for winding the fishing line around the spool is larger as the spool diameter is increased. Therefore, the distance between the root of the fishing rod attachment and the housing must be increased to provide space for the rotor to rotate. That is, the larger diameter of the bobbin results in enlargement of the spinning reel.In addition, when the reciprocating stroke of the spool is increased, the length of a reciprocating mechanism in the front-rear direction needs to be increased. Therefore, the housing needs to be enlarged to accommodate the reciprocating mechanism. That is, the spinning reel must be larger due to the larger stroke of the reciprocating motion of the spool.On the other hand, it has been found that a finer winding pitch of the fishing line effectively reduces the size of the spinning reel as compared with the above technology. However, it has been found that a finer pitch of winding also results in a more complicated structure of the spinning reel, such as a reduction mechanism having a high reduction ratio and components difficult to manufacture, such as a worm shaft having a thin wall thickness between the grooves. Complicated spin-wound bobbin structures can be connected with high manufacturing costs.A possible configuration of the above-mentioned reduction mechanism with a high reduction ratio may be, for example, a simple gear train with small modular gears. However, the use of small modular gears requires consideration of the strength of the gears in the construction of the gears. To construct appropriate gears depending on the size of the spool and the thickness of the fishing line, many prototypes must be made and complex strength calculations must be performed.It has thus been found that the prior art for solving the problem at the dead points is associated with the various problems described above.Therefore, in the present invention, a basic structure useful in the construction of reciprocating mechanisms and coils is proposed. That is, in the present invention, reference values to be used in the design of the reciprocating mechanism and the spool are set, and these reference values are used for the design of the reciprocating mechanism and the spool.An object of the present invention is to provide a spinning reel having a basic structure capable of appropriately solving the problems of conventional spinning reels.A spinning reel according to an aspect of the present invention includes a reel shaft, a reel, a pinion, a reciprocating mechanism, and an intermediate gear. The spool shaft is supported movably in the front-rear direction with respect to the spool. The coil is connected to the coil shaft. The fishing line may be wound around the spool. The pinion is rotatably mounted on the coil body. The reciprocating mechanism reciprocates the spool shaft.The intermediate gear is disposed between the pinion gear and the reciprocating mechanism. The intermediate gear reduces the rotational movement of the pinion and transmits it to the reciprocating mechanism. The first value, which is obtained by dividing the stroke distance of the spool shaft by the winding pitch of the fishing line and the modulus (M) of the idler gear, is greater than or equal to 60.The spinning reel is designed so that the first value obtained by dividing the stroke distance of the spool shaft by the winding pitch of the fishing line and the modulus (M) of the idler gear is greater than or equal to 60. The problems of the conventional spinning reels can be suitably solved by the construction of a reciprocating mechanism and a reel having this configuration.In the spinning reel according to another aspect of the present invention, the first value obtained by dividing the stroke distance of the spool shaft by the winding pitch of the fishing line and the modulus (M) of the intermediate gear is preferably less than or equal to 150.In the spinning reel according to another aspect of the present invention, the winding pitch is preferably less than or equal to 1.0 mm. In the spinning reel according to another aspect of the present invention, preferably, the spool includes a spool body around the outer periphery of which a fishing line can be wound, and a front flange extending radially outward from a front end of the spool body. In this case, the outer diameter of the front flange is less than 60 mm.In the spinning reel according to another aspect of the present invention, it is preferable that the intermediate gear includes a first intermediate gear and a second intermediate gear. The smaller one of the first intermediate gear module (M) and the second intermediate gear module (M) is selected as the intermediate gear module (M).The first intermediate gear is rotatable about a first axis parallel to the spool axis. The first intermediate gear has a first larger diameter gear that meshes with the pinion gear, and a first smaller diameter gear than the first larger diameter gear that integrally rotates with the first larger diameter gear.The second intermediate gear is rotatable about a second axis that is parallel to the first axis. The second intermediate gear has a second larger diameter gear that meshes with the first smaller diameter gear and a second smaller diameter gear that is smaller in diameter than the second larger diameter gear and rotates integrally with the second larger diameter gear. The reciprocating mechanism has an output gear that meshes with the second smaller-diameter gear and a worm shaft that rotates together with the output gear.Since the fishing line can be wound around the spool by this configuration while reducing the speed of reciprocation of the spool shaft, the problems of conventional spinning reels can be suitably solved with a relatively simple structure.The spinning reel of the present invention can suitably solve the problems of the conventional spinning reels.A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein: FIG. 1 is a side view of the spinning reel according to an embodiment of the present invention; FIG. 2 is a side view of the spin reel from which the side cover and the body guard have been removed; FIG. 3 is a side view of the spool; FIG. 4 is an exploded perspective view for explaining the oscillation mechanism; FIG. 5 is a side view for explaining the reduction mechanism; FIG. 6 is a side view for explaining a configuration used for increasing the winding amount of the fishing line; and FIG. 7 is a table showing the numerical values of the basic structure and the overall evaluation for casting and winding for conventional spinning reels and the spinning reel of the present invention.Selected embodiments will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the several drawings.As shown in FIG. 1, a spinning reel 1 aimed at an embodiment of the present invention includes a bobbin 3, a handle 5, a spool 7, and a rotor 9.

The spool shaft 15 is inserted through the inner peripheral portion of the cylindrical pinion 17. The spool shaft 15 can be reciprocated with respect to the spool 3 by the oscillating mechanism 21.The coil shaft 15 has a coil axis X 1. The front-rear direction and the axial direction are directions in which the coil axis X 1 extends. The radial direction is the direction away from the coil axis X 1, and the circumferential direction is the direction around the coil axis X 1.The oscillation mechanism 21 moves the spool shaft 15 in the front-rear direction. The oscillating mechanism 21 moves, for example, the spool shaft 15 in the front-rear direction in association with the rotation of the handle shaft 11.As illustrated in FIGS. 2 and 4, the oscillation mechanism 21 includes a worm shaft 23, a carriage 25, and a worm shaft gear 27 (an example of a drive gear). The worm shaft 23 rotates to move the spool shaft 15 and the carriage 25 in the front-rear direction. The worm shaft 23 is disposed in parallel with the spool shaft 15. The worm shaft 23 is rotatably supported on the bobbin 3, and the worm shaft 23 has a rotation axis W 1.The worm shaft 23 has a shaft body 23 aand a groove portion 23 b. The shaft body 23 ais a shaft member that is longer in one direction. The shaft body 23 aextends in the axial direction in which the rotation axis W 1 extends. The groove portion 23 bis disposed on the outer circumferential surface of the shaft body 23 a. The groove portion 23b is engaged with a ratchet member 26 which will be described later.The carriage 25 is mounted on the spool shaft 15. For example, the carriage 25 is fixed to the rear end of the spool shaft 15.

In this state, the worm shaft 23 rotates integrally with the worm shaft gear 27.As shown in FIG. 2, the pinion 17 has a cylindrical shape and is rotatably supported on the spool 3. The pinion gear 17 is disposed on the radially outer side of the spool shaft 15. The pinion 17 rotates with respect to the spool shaft 15 and about the spool axis X 1.As shown in FIG. 5, the reduction gear 19 reduces the rotational movement of the pinion 17 and transmits it to the oscillating mechanism 21, and in FIG. 5, the teeth of the individual gears are omitted. The portions in which the gears mesh are shown shaded.The reduction gear 19 is disposed between the pinion 17 and the oscillation mechanism 21. For example, the reduction gear 19 is disposed between the pinion 17 and the worm shaft gear 27.The reduction gear 19 has a first intermediate gear 31 and a second intermediate gear 33. the first intermediate gear 31 is rotatable about a first axis A 1 parallel to the spool axis X 1. The first intermediate wheel 31 is rotatably mounted on the coil body 3. The first intermediate gear 31 has a first module M 1. The first modulus M 1 is calculated by dividing the diameter d 1 of the pitch circle of the first intermediate gear 31 by the number of teeth z 1 of the first intermediate gear 31. This formula is expressed as "M1=d1 / z1". In FIG. 5, the guide line indicating the number of teeth z 1 of the first intermediate gear 31 is indicated by the dashed double line.The first intermediate gear 31 has a first larger-diameter gear 31 aand a first smaller-diameter gear 31 b. The first larger diameter gear 31a meshes with the pinion 17. The rotation axis of the first larger diameter gear 31 ais the first axis A 1. The first smaller-diameter gear 31 bhas a smaller diameter than the first larger-diameter gear 31 a. The first smaller-diameter gear 31 bis formed integrally with the first larger-diameter gear 31 aand rotates integrally with the first larger-diameter gear 31 a. The rotation axis of the first smaller-diameter gear 31 bis the first axis A 1.The second intermediate gear 33 is rotatable about a second axis A 2 parallel to the first axis A 1. The second intermediate gear 33 is rotatably supported on the spool 3. The second idler gear 33 has a second module M 2. The second modulus M 2 is calculated by dividing the diameter of the pitch circle d 2 of the second intermediate gear 33 by the number of teeth z 2 of the second intermediate gear 33. This calculation formula is expressed as "M2=d2 / z2". In FIG. 5, the guide line indicating the number of teeth z 2 of the second intermediate gear 33 is indicated by the dashed double line.The second intermediate gear 33 has a second larger-diameter gear 33 aand a second smaller-diameter gear 33 b.

The second smaller-diameter gear 33 bis formed integrally with the second larger-diameter gear 33 aand rotates integrally with the second larger-diameter gear 33 a. The rotation axis of the second smaller-diameter gear 33 bis the second axis A 2. The second smaller-diameter gear 33 bengages with the worm shaft gear 27.When the handle shaft 11 is rotated by the rotational movement of the handle 5, the drive gear 13 is rotated. The rotation of the drive gear 13 is transmitted to the pinion gear 17, and the rotation of the pinion gear 17 is transmitted to the worm shaft gear 27 via the above-described reduction gear 19. The rotation of the worm shaft gear 27 is transmitted to the worm shaft 23, and the rotation of the worm shaft 23 moves the carriage 25 and the spool shaft 15 in the front-rear direction.As shown in Figs. 1 and 2, the rotor 9 is used for winding a fishing line onto the spool 7. The rotor 9 is disposed at a front portion of the bobbin 3, and is formed to be rotatable with respect to the bobbin 3. The rotor 9 is disposed on the radially outer side of the pinion gear 17 and is mounted so as to be integrally rotatable with respect to the pinion gear 17.When the handle shaft 11 is rotated by the rotational operation of the handle 5, the drive gear 13 rotates. The rotor 9 rotates in association with the rotation of the pinion 17.The spinning reel 1 having the above-described configuration is configured as follows. The outer diameter R of the front flange 7 billustrated in FIGS. 3 and 6 is less than 60 mm. For example, the outer diameter R of the front flange 7 bis preferably greater than or equal to 35 mm and less than 60 mm. More preferably, the outer diameter R of the front flange 7 bis greater than or equal to 40 mm and less than 56 mm. The outer diameter R of the front flange 7 bis determined by the outer circumferential surface 7 b 1 of the front flange 7 b.The winding pitch P of the fishing line is less than or equal to 1.0 mm. For example, the winding pitch P of the fishing line is preferably greater than or equal to 0.4 mm and less than or equal to 1.0 mm. Preferably, the winding pitch P of the fishing line may be greater than or equal to 0.55 mm and less than or equal to 0.90 mm. The winding pitch P of the fishing line is the axial distance between adjacent fishing lines on the spool body 7a.The winding pitch P of the fishing line is not constant but depends on the structure of the oscillating mechanism 21. Therefore, the average winding pitch P is used here. The average winding pitch is detected by dividing a stroke distance (S×2) by the number of revolutions of the rotor 9 during one reciprocation of the coil shaft 15.The first value (S / (P·M)) obtained by dividing the stroke distance S of the spool shaft 15 by the smaller module M from the first module M 1 of the first intermediate gear 31 and the second module M 2 of the second intermediate gear 33 is greater than or equal to 60; the first value (S / (P·M)) obtained by dividing the stroke distance S of the spool shaft 15 by the smaller module M from the first module M 1 of the first intermediate gear 31 and the second module M 2 of the second intermediate gear 33 is less than or equal to 150. These relationships are expressed by the relational expression "60≤S / (P·M))≤150".As shown in FIG. 6, the stroke distance S of the spool shaft 15 is the amount by which the spool shaft 15 is moved in the front-rear direction by the oscillation mechanism 21. Preferably, the stroke distance S of the spool shaft 15 is greater than or equal to 12 mm and less than or equal to 25 mm. More preferably, the stroke distance S of the spool shaft 15 is greater than or equal to 13 mm and less than or equal to 23 mm.FIG. 7 shows, in tabular form, each of the above-described numerical values and overall evaluation for casting and winding a spinning reel 1 in which the embodiments of the present invention have been implemented (Assumed Models 1 and 2), a spinning reel 1 which can implement embodiments of the present invention by changing the specifications of the Assumed Models 1 and 2 (Comparative Model 3), and conventional spinning reels having an idler gear or a gear corresponding to an idler gear (Conventional Models 1-3).The "overall evaluation for casting and winding" in FIG. 7 shows the results of a plurality of tests performed to evaluate casting and winding (fishing line winding) for each of the "size categories A, B, C" of each spinning reel on the basis of sensory evaluations and grades by a paired comparison test method with respect to quietness, strain feeling, winding stability, and the like. In the code for "total rating for casting and winding", the letters stand for the size category and the numerical value for the rating.In the size category A, for example, the total score A 1 of the adopted model 1 has the highest score compared to the total score A 2 of the conventional model 1. in the size category B, the total score B 1 of the adopted model 2 has the highest score compared to the total score B 2 of the conventional model 2. in the size category C, the total score C 1 of the comparative model 3 has the highest score compared to the total score C 2 of the conventional model 3. in this way, the total scores A 1, B 1, and C 1 of the adopted models 1, 2, and the comparative model 3 in each of the size categories A, B, and C have acquired values higher than the total scores A 2, B 2, and C 2 of the conventional models.The above-described spinning reel 1 has the following features. The spinning reel 1 is configured such that the first value (S / (P·M)) obtained by dividing the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line and the modulus M of the idler gears 31, 33 is equal to or larger than 60. By thus constructed construction of the oscillating mechanism 21 and the spool 7, the problems of the conventional spinning reels can be suitably solved.In the spinning reel 1, the first value (S / (P·M)) obtained by dividing the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line and the modulus M of the idler gears 31, 33 is less than or equal to 150. In the spinning reel 1, the winding pitch P of the fishing line is less than or equal to 1.0 mm. In the spinning reel 1, the outer diameter R of the front flange 7b is smaller than 60 mm. Since the spinning reel 1 has the first intermediate gear 31 and the second intermediate gear 33, the fishing line can be wound around the spool body 7a because the speed of movement of the spool shaft 15 in the front-rear direction is reduced. As a result, the problems of the conventional spinning reels can be suitably solved with a relatively simple structure.Embodiments of the present invention may be used in a spinning reel.REFERENCE NUMERALS1 Spinning reel 1 aSide cover 1 bBody guard 3 Bobbin 5 Handle 7 Reel 7 a Body 7 bFront flange 7 b 1 Outer peripheral surface 7 c Schürze part 7 c 1 Rear flange 7 c 2 Cylindrical part 9 Rotor 10 Reel collar 11 Handle shaft 13 Drive wheel 15 Reel shaft 17 Pinion 19 Reduction gear 21 Oscillating mechanism 23 Worm shaft 23 aShaft body 23 b Nuten portion 25 Slider 26 Ratchet member 27 Worm shaft wheel 27 aWheel body 27 b Einführungs hole 31 First intermediate gear 31 aFirst larger gear 31 bFirst smaller gear 33 Second intermediate gear 33 aSecond larger gear 33 bSecond smaller gear A 1First axis A 2Second axis d 1 Diameter d 2 Diameter P Winding pitch R diameter S: stroke distance W 1: rotation axis W 2: rotation axis X 1: spool axis X 2: central axis z 1: number of teeth (the first intermediate gear 31): z 2: number of teeth (the second intermediate gear 33)
