Description

The present invention relates to a spinning reel.It is known that at the dead points of a spinning reel, various problems occur as the spool reciprocates, that is, at the foremost and rearmost positions of the spool. For example, when the fishing line is released or ejected, noises are generated and the release resistance of the fishing line increases 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 coil diameter and a coil having an extended stroke distance has been proposed. JP 2019-106 898 A discloses such a device, for example. Further, an apparatus having a technology for making the winding pitch of the fishing line finer has been proposed. For example, JP H11-86 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 becomes larger as the spool diameter is increased. Therefore, the distance between the fixing foot of the fishing rod and the housing must be increased to allow space for the rotor to rotate. That is, the larger diameter of the bobbin results in enlargement of the spinning reel.Moreover, when the reciprocating mechanism stroke distance of the spool is increased, the length of a reciprocating mechanism in the front-rear direction needs to be increased. It is therefore necessary to enlarge the housing to accommodate the reciprocating mechanism. That is, the spinning reel must be larger due to the larger stroke distance of the reciprocating motion of the spool.On the other hand, it has been found that the size of the spinning reel can be effectively reduced as compared with the above-mentioned technology, if the winding pitch of the fishing line is finer. 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 difficult-to-manufacture components, such as a worm shaft having a thin wall thickness between the grooves. It will be appreciated that more complicated spin-wound bobbin structures can be associated with high manufacturing costs.In addition, since the thickness of the used fishing line varies with the size of the spool, it is difficult to set an appropriate winding pitch for the fishing line depending on the thickness of the fishing line.Thus, it has been found that the prior art for solving the problem at the dead points is associated with the various problems described above.Therefore, the present invention proposes a basic structure useful in the construction of a reciprocating mechanism and coils. That is, in the present invention, reference values to be used in the construction of the reciprocating mechanism and the spool are set, and these reference values are used to design the reciprocating mechanism and the spool.The present invention aims to provide a spinning reel having a basic structure which can suitably solve the problems of conventional spinning reels.A spinning reel according to an aspect of the present invention includes a reel body, a reel shaft, and a reel. The spool shaft is movably supported on the reel body in the front-rear direction at a reciprocal stroke distance. The coil is connected to the coil shaft. The spool has a spool into which a fishing line can be wound. The coil also has a front flange extending radially outward from the front end of the bobbin. The outer diameter of the front flange is here less than 60 mm. The first value obtained when dividing the stroke distance of the spool shaft by the winding pitch of the fishing line is equal to or larger than 20.In the spinning reel, the front flange has an outer diameter of less than 60 mm. The first value obtained when dividing the stroke distance of the spool shaft by the winding pitch of the fishing line is equal to or larger than 20 By this configuration, in a spinning reel in which the front flange has an outer diameter of less than 60 mm, the amount of fishing line that can be wound on the spool in the front-rear direction can be suitably increased. By constructing a reciprocating mechanism and a spool using this configuration, the problems of the conventional spinning reels can be solved.In the spinning reel according to another aspect of the present invention, the first value resulting from dividing the stroke distance of the spool shaft by the winding pitch of the fishing line is preferably less than or equal to 30.In the spinning reel according to another aspect of the present invention, the second value resulting from multiplying the first value by the outer diameter of the front flange is preferably 950 or more and 1500 or less. By this configuration, in a spinning reel in which the front flange has an outer diameter of less than 60 mm, by designing the reciprocating mechanism and the spool in accordance with the outer diameter of the front flange, the problems of the conventional spinning reels can be suitably solved.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. By constructing a reciprocating mechanism and a spool using this configuration, the problems of the conventional spinning reels can be solved appropriately.The spinning reel according to another aspect of the present invention preferably further includes a handle, a pinion, a first middle gear, a second middle gear, and a reciprocating mechanism. The handle is rotatably mounted on the roller body. The gearwheel is rotatably mounted on the roller body. The rotation of the handle is transmitted to the gear.The first center gear is rotatable about a first axis parallel to the spool axis. The first middle gear has a first large diameter gear engaged with the gear and a first small diameter gear smaller in diameter than the first large diameter gear and rotating together with the first large diameter gear.The second center gear is rotatable about a second axis that is parallel to the first axis. The second middle gear has a second large diameter gear engaged with the first small diameter gear and a second small diameter gear smaller in diameter than the second large diameter gear and integrally rotates with the second large diameter gear.The reciprocating mechanism reciprocates the spool shaft. The reciprocating mechanism has a driven gear engaged with the second small diameter gear and a worm shaft rotating together with the driven gear.Since the fishing line can be wound around the spool while reducing the speed of reciprocation of the spool shaft, the problems of conventional spinning reels can be 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 understanding of the invention and many attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description taken in conjunction 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 reciprocating 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 numerical values of the basic structure and comprehensive throwing and winding values for conventional spinning reels and the spinning reel of the present invention.Selected embodiments will now be described with reference to the accompanying drawings, in which like reference numerals designate corresponding or identical elements throughout the several drawings.As shown in FIG. 1, a spinning reel 1 to which an embodiment of the present invention is applied includes a reel body 3, a handle 5, a spool 7, and a rotor 9.

The radial direction is the direction away from the coil axis X 1, and the circumferential direction and the rotational direction are directions around the coil axis X 1.The reciprocating mechanism 21 moves the spool shaft 15 in the front-rear direction. The reciprocating mechanism 21 moves, for example, the spool shaft 15 in association with the rotation of the handle shaft 11 in the front-rear direction. The reciprocating mechanism 21 is disposed in an inner space of the reel body 3.As illustrated in FIGS. 2 and 4, the reciprocating mechanism 21 includes a worm shaft 23, a carriage 25, and a worm shaft gear 27 (an example of a driven gear).

In this state, the worm shaft 23 rotates integrally with the worm shaft gear 27.As shown in FIG. 2, the gear 17 is formed cylindrically and is rotatably supported by the reel body 3. The gear 17 is disposed on the radially outer side of the spool shaft 15. The gear 17 rotates with respect to the spool shaft 15 and about the spool axis X 1.As shown in FIG. 5, the reduction mechanism 19 reduces the rotation of the gear 17 and transmits it to the reciprocating mechanism 21, and in FIG. 5, the teeth of the individual gears are omitted. The areas in which the gears mesh are shaded.The reduction mechanism 19 is disposed between the gear 17 and the reciprocating mechanism 21. The reduction mechanism 19 is disposed between the gear 17 and the worm shaft gear 27, for example.The reduction mechanism 19 includes a first center gear 31 and a second center gear 33. the first center gear 31 is rotatable about a first axis A 1 parallel to the spool axis X 1. The first middle gearwheel 31 is rotatably mounted on the roller body 3. The first middle gear 31 has a first large diameter gear 31 aand a first small diameter gear 31 b.The first large diameter gear 31 ais engaged with the gear 17. the rotation axis of the first large diameter gear 31 ais the first axis A 1.

The second small diameter gear 33 bis meshed with the worm shaft gear 27.When the handle shaft 11 is rotated by the turning operation of the handle 5, the drive gear 13 is rotated. The rotation of the drive gear 13 is transmitted to the gear 17, and the rotation of the gear 17 is transmitted to the worm shaft gear 27 via the above-described reduction mechanism 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 part of the reel body 3 and is formed to be rotatable with respect to the reel body 3. The rotor 9 is disposed on the radially outer side of the gear 17 and is mounted so as to be integrally rotatable with respect to the gear 17.When the handle shaft 11 is rotated by the rotating operation of the handle 5, the drive gear 13 rotates, and the rotation of the drive gear 13 is transmitted to the gear 17. The rotor 9 rotates in association with the rotation of the gear 17.The spinning reel 1 having the above-described configuration is constructed 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.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 7a.The winding pitch P of the fishing line is not constant but depends on the structure of the reciprocating mechanism 21. Therefore, here, the average winding pitch of the fishing line is used as the winding pitch P of the fishing line. The average winding pitch of the fishing line is obtained by dividing one revolution of the stroke distance (S × 2) by the number of revolutions of the rotor 9 during one revolution of the reciprocating motion of the spool shaft 15.The first value (S / P) resulting from dividing the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line is greater than or equal to 20. The first value (S / P) resulting from dividing the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line is less than or equal to 30.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 reciprocating mechanism 21. The stroke distance S of the spool shaft 15 is preferably greater than or equal to 12 mm and less than or equal to 25 mm.The second value ((S / P)×R) resulting from multiplying the first value (S / P) resulting from dividing the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line and the outer diameter R of the front flange 7 bis greater than or equal to 950 and less than or equal to 1500. This relationship is expressed by the relational expression "950≤{(S / P)×R}≤1500".FIG. 7 shows, in tabular form, each of the numerical values described above and comprehensive evaluations for the ejection and retrieval of a spinning reel 1 to which embodiments of the present invention have been applied (adopted models 1 and 2), a spinning reel 1 which can use embodiments of the present invention by changing the specifications of adopted models 1 and 2 (comparative model 3), and conventional spinning reels (conventional models 1-6).The "comprehensive evaluations for the casting and feeding" in FIG. 7 show the results of a plurality of tests performed to evaluate the casting and feeding (winding of the fishing line) 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 the "comprehensive evaluations 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 comprehensive rating A 1 of the adopted model 1 has the highest rating as compared with the comprehensive ratings A 2 and A 3 of the conventional models 1 and 4, respectively. in the size category B, the overall rating B 1 of the adopted model 2 has the highest rating as compared with the overall ratings B 2 and B 3 of the conventional models 2 and 5, respectively. in the size category C, the overall rating C 1 of the comparative model 3 has the highest rating as compared with the overall ratings C 2 and C 3 of the conventional models 3 and 6, respectively. That is, the overall ratings A 1, B 1 and C 1 of the adopted models 1, 2 and the comparative model 3 have reached in each of the size categories A, b and C are the highest score.The above-described spinning reel 1 has the following features. In the spinning reel 1 in which the front flange 7b has an outer diameter R of less than 60 mm, the first value (S / P) resulting from the division of the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line is greater than or equal to 20.In the spinning reel 1 in which the front flange 7b has an outer diameter R of less than 60 mm, the problems of the conventional spinning reels can be suitably solved by setting the first value (S / P) resulting from the division of the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line to be less than or equal to 30.In the spinning reel 1 in which the front flange 7 bhas an outer diameter R of less than 60 mm, the second value ((S / P)×R) resulting from multiplying the first value (S / P) resulting from dividing the stroke distance S of the spool shaft 15 by the winding pitch P of the fishing line by the outer diameter R of the front flange 7 bis greater than or equal to 950 and less than or equal to 1500. Consequently, the problems of conventional spinning reels can be suitably solved by constructing the reciprocating mechanism 21 and the spool 7 in accordance with the outer diameter R of the front flange 7b.In the spinning reel 1 in which the front flange 7 bhas an outer diameter R of less than 60 mm, the problems of the conventional spinning reels can be suitably solved by setting the winding pitch P to be less than or equal to 1.0 mm.Since the spinning reel 1 in which the outer diameter R of the front flange 7 bis less than 60 mm has the first middle gear 31 and the second middle gear 33, it is possible to wind the fishing line around the spool 7 abecause the speed of movement of the spool shaft 15 in the front-rear direction is reduced. Thus, the problems of the conventional spinning reels can be solved appropriately with a relatively simple construction.Embodiments of the present invention may be used in a spinning reel.REFERENCE NUMERALS1 Spinning reel 1 aSide cover 1 b Body guard 3 Reel body 5 Handle 7 Reel 7 a Spulenkörper 7 bFront flange 7 b 1 Outer peripheral surface 7 c Randbereich 7 c 1 Rear flange 7 c 2 Cylindrical portion 9 Rotor 10 Reel flange 11 Handle shaft 13 Drive gear 15 Reel shaft 17 Gear 19 Reduction mechanism 21 Reciprocating mechanism 23 Worm shaft 23 aShaft body 23 b Nut portion 25 Slider 26 Ratchet member 27 Worm shaft gear 27 a Zahnrad body 27 b Einsteck hole 31 First middle gear 31 aFirst large diameter gear 31 bFirst small diameter gear 33 Second middle gear 33 aSecond large diameter gear 33 bSecond small diameter gear A 1First axis A 2Second axis P Winding pitch R outer diameter S stroke distance W1 rotation axis W2 rotation axis X1 coil axis X2 center axis
