Description

Technical Field

[0001] The present invention relates to a spinning reel.

Background Art

[0002] In a spinning reel, various problems are known to occur at dead points when the spool reciprocates back and forth, that is, at the position where the spool is arranged at the most forward position and the position where the spool is arranged at the most rearward position. For example, when the fishing line is released, at the dead point, the fishing lines come into contact with each other, resulting in the generation of noise and an increase in the release resistance of the fishing line. As a result, it is known that the casting distance decreases. Therefore, in order to solve the problems at this dead point, technologies such as increasing the diameter of the spool, extending the stroke of the reciprocating movement of the spool (see, for example, Patent Document 1), and making the winding pitch of the fishing line finer (see, for example, Patent Document 2) have been proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the prior art, when the diameter of the spool is increased, the rotor for winding the fishing line around the spool also has a larger diameter. Here, in order to secure a space for allowing the rotation of this rotor, it is necessary to increase the distance from the fishing rod mounting leg portion to the housing portion. That is, there is a problem that the spinning reel becomes larger due to the increase in the diameter of the spool.

[0005] Further, when the stroke of the reciprocating movement of the spool is increased, the length of the reciprocating movement mechanism in the front-rear direction increases. Therefore, in order to accommodate this reciprocating movement mechanism, it is necessary to increase the size of the housing portion. That is, an increase in the stroke amount of the reciprocating movement of the spool causes a problem that the housing portion, that is, the spinning reel becomes larger.

[0006] On the other hand, compared with the above-described technique, when the winding pitch of the fishing line is made finer, it is effective in suppressing the enlargement of the spinning reel. However, the finer the winding pitch of the fishing line is made, the more necessary it is to prepare a complicated structure such as a reduction mechanism with a large reduction ratio or a difficult-to-manufacture part such as a worm shaft with a thin wall thickness between grooves. That is, problems occur such that the structure of the spinning reel becomes complicated and the manufacturing cost of the spinning reel becomes high.

[0007] For example, as a form in which the reduction mechanism with a large reduction ratio is configured by a simple gear train, it is conceivable to configure the gears with a small module. However, when the gears are configured with a small module, it is necessary to design the gears while considering the strength of the gears. Therefore, in order to design appropriate gears according to the thickness of the fishing line and the size of the spool, it is necessary to perform a lot of trial productions and complicated strength calculations.

[0008] As described above, the conventional techniques for solving the problems at the dead points have various problems as described above.

[0009] Therefore, in the present invention, a basic structure useful in designing the reciprocating movement mechanism and the spool is proposed. That is, in the present invention, reference values for designing the reciprocating movement mechanism and the spool are set, and the reciprocating movement mechanism and the spool are designed using these reference values.

[0010] An object of the present invention is to propose a spinning reel having a basic structure that can preferably solve the problems of conventional spinning reels.

Means for Solving the Problems

[0011] The spinning reel according to one aspect of the present invention includes a spool shaft, a spool, a pinion gear, a reciprocating mechanism, and an intermediate gear. The spool shaft is supported so as to be movable in the front-rear direction with respect to the reel body. The spool is connected to the spool shaft. Fishing line is wound around the spool. The pinion gear is rotatably supported by the reel body. The reciprocating mechanism reciprocates the spool shaft in the front-rear direction.

[0012] The intermediate gear is disposed between the pinion gear and the reciprocating mechanism. The intermediate gear decelerates the rotation of the pinion gear and transmits it to the reciprocating mechanism. The value obtained by dividing the stroke amount of the spool shaft by the winding pitch of the fishing line and the module of the intermediate gear is 60 or more.

[0013] This spinning reel is configured such that the value obtained by dividing the stroke amount of the spool shaft by the winding pitch of the fishing line and the module of the intermediate gear is 60 or more. By designing the reciprocating mechanism and the spool using this configuration, the problems of conventional spinning reels can be preferably solved.

[0014] In the spinning reel according to another aspect of the present invention, it is preferable that the value obtained by dividing the stroke amount of the spool shaft by the winding pitch of the fishing line and the module of the intermediate gear is 150 or less.

[0015] In the spinning reel according to another aspect of the present invention, it is preferable that the winding pitch is 1.0 mm or less.

[0016] In the spinning reel according to another aspect of the present invention, it is preferable that the spool has a thread winding barrel portion around which fishing line is wound on the outer periphery, and a front flange extending radially outward from the front end of the thread winding barrel portion. In this case, the outer diameter of the front flange is less than 60 mm.

[0017] In the spinning reel according to another aspect of the present invention, the intermediate gear preferably has a first intermediate gear and a second intermediate gear. The smaller of the module of the first intermediate gear and the module of the second intermediate gear is selected as the module of the intermediate gear.

[0018] The first intermediate gear is rotatably provided about a first axis parallel to the spool axis. The first intermediate gear has a first large-diameter gear that meshes with a pinion gear, and a first small-diameter gear that is smaller in diameter than the first large-diameter gear and rotates integrally with the first large-diameter gear.

[0019] The second intermediate gear is rotatably provided about a second axis parallel to the first axis. The second intermediate gear has a second large-diameter gear that meshes with the first small-diameter gear, and a second small-diameter gear that is smaller in diameter than the second large-diameter gear and rotates integrally with the second large-diameter gear. The reciprocating mechanism has a driven gear that meshes with the second small-diameter gear, and a worm shaft that rotates integrally with the driven gear. With this configuration, the fishing line can be wound around the spool while decelerating the movement of the spool axis in the front-rear direction. Therefore, with a relatively simple structure, the problems of conventional spinning reels can be preferably solved.

Advantages of the Invention

[0020] The spinning reel of the present invention can preferably solve the problems of conventional spinning reels.

Embodiments for Carrying Out the Invention

[0022] As shown in FIG. 1, a spinning reel 1 adopting an embodiment of the present invention includes a reel body 3, a handle 5, a spool 7, and a rotor 9. As shown in FIG. 2, the spinning reel 1 further includes a handle shaft 11, a drive gear 13, a spool shaft 15, a pinion gear 17, a reduction mechanism 19, and an oscillating mechanism 21 (an example of a reciprocating movement mechanism). Note that FIG. 2 is a view in which the side cover 1a and the main body guard 1b of the spinning reel 1 shown in FIG. 1 are removed.

[0023] As shown in FIG. 1, the handle 5 is rotatably supported by the reel body 3. In the present embodiment, an example in which the handle 5 is disposed on the left side of the reel body 3 is shown. The handle 5 may be disposed on the right side of the reel body 3. The handle 5 is attached to the handle shaft 11.

[0024] As shown in FIG. 2, the handle shaft 11 is rotatably supported by the reel body 3. The drive gear 13 is attached to the handle shaft 11 so as to be rotatable integrally with the handle shaft 11. The drive gear 13 meshes with the pinion gear 17.

[0025] A fishing line is wound around the spool 7. As shown in FIG. 2, the spool 7 is configured to be movable in the front-rear direction with respect to the reel body 3 together with the spool shaft 15. The spool 7 is connected to the spool shaft 15. For example, the spool 7 is connected to the tip of the spool shaft 15 via a drag mechanism (not shown).

[0026] The spool 7 has a central axis X2. In a state where the spool 7 is connected to the spool shaft 15, the central axis X2 of the spool 7 is coaxial with the spool axis X1 described later.

[0027] As shown in FIG. 3, the spool 7 has a thread winding body portion 7a, a front flange 7b, and a skirt portion 7c. Fishing line is wound around the outer periphery of the thread winding body portion 7a. The thread winding body portion 7a is formed in a cylindrical shape. The front flange 7b extends radially outward from the front end of the thread winding body portion 7a. The front flange 7b is formed integrally with the thread winding body portion 7a. The front flange 7b is formed in a disk shape. The front flange 7b has an outer diameter R. The outer diameter R of the front flange 7b is defined by the outer peripheral surface 7b1 of the front flange 7b. A spool collar 10 is disposed radially outside the front flange 7b (see FIG. 2). The spool collar 10 covers the outer peripheral surface 7b1 of the front flange 7b.

[0028] The skirt portion 7c is formed integrally with the rear end of the thread winding body portion 7a. The skirt portion 7c has a rear flange 7c1 and a cylindrical portion 7c2. The rear flange 7c1 extends radially outward from the rear end of the thread winding body portion 7a. The rear flange 7c1 is formed integrally with the thread winding body portion 7a. The rear flange 7c1 is formed in a disk shape. The cylindrical portion 7c2 extends rearward from the outer peripheral portion of the rear flange 7c1. The cylindrical portion 7c2 is formed integrally with the rear flange 7c1. The cylindrical portion 7c2 is formed in a cylindrical shape.

[0029] As shown in FIG. 2, the spool shaft 15 is supported so as to be movable in the front-rear direction with respect to the reel body 3. The spool shaft 15 is inserted into the inner peripheral portion of a cylindrical pinion gear 17. The spool shaft 15 reciprocates in the front-rear direction with respect to the reel body 3 by the operation of the oscillating mechanism 21.

[0030] The spool shaft 15 has a spool axis X1. The front-rear direction and the axial direction are the directions in which the spool axis X1 extends. The radial direction is the direction away from the spool axis X1. The circumferential direction and the rotational direction are the directions around the spool axis X1.

[0031] The oscillating mechanism 21 moves the spool shaft 15 in the front - rear direction. The oscillating mechanism 21, for example, moves the spool shaft 15 in the front - rear direction in conjunction with the rotation of the handle shaft 11. The oscillating mechanism 21 is disposed in the internal space of the reel body 3.

[0032] As shown in FIGS. 2 and 4, the oscillating mechanism 21 includes a worm shaft 23, a slider 25, and a worm shaft gear 27 (an example of a driven gear). The worm shaft 23 rotates to move the spool shaft 15 and the slider 25 in the front - rear direction. The worm shaft 23 is disposed parallel to the spool shaft 15. The worm shaft 23 is rotatably supported by the reel body 3. The worm shaft 23 has a rotation axis W1.

[0033] The worm shaft 23 has a shaft body 23a and a groove portion 23b. The shaft body 23a is a shaft member that is long in one direction. The shaft body 23a extends in the axial direction in which the rotation axis W1 extends. The groove portion 23b is provided on the outer peripheral surface of the shaft body 23a. A claw member 26, which will be described later, engages with the groove portion 23b.

[0034] The slider 25 is attached to the spool shaft 15. For example, the slider 25 is fixed to the rear end of the spool shaft 15. The slider 25 moves in the front - rear direction by the rotation of the worm shaft 23.

[0035] For example, as shown in FIG. 4, a claw member 26 is attached to the slider 25. The claw member 26 is rotatably attached to the spool shaft 15 and the slider 25. The claw member 26 engages with the groove portion 23b of the worm shaft 23. Thereby, when the worm shaft 23 rotates, the claw member 26 moves along the groove portion 23b of the worm shaft 23. Thereby, the slider 25 moves in the front - rear direction.

[0036] As shown in FIGS. 2 and 4, the worm shaft gear 27 is mounted on the worm shaft 23. For example, the worm shaft gear 27 has a rotation axis W2. The worm shaft gear 27 is mounted on the worm shaft 23 such that the rotation axis W2 of the worm shaft gear 27 is concentric with the rotation axis W1 of the worm shaft 23. The worm shaft gear 27 rotates integrally with the worm shaft 23.

[0037] As shown in FIG. 4, the worm shaft gear 27 has a gear body 27a and an insertion hole 27b. The gear body 27a is formed in a disk shape. The gear body 27a meshes with a second small-diameter gear 33b (described later) of the speed reduction mechanism 19.

[0038] The insertion hole 27b is provided in the gear body 27a. For example, the insertion hole 27b penetrates the gear body 27a in the axial direction in which the rotation axis W2 of the worm shaft gear 27 extends. The worm shaft 23 is inserted into the insertion hole 27b. In this state, the worm shaft 23 rotates integrally with the worm shaft gear 27.

[0039] As shown in FIG. 2, the pinion gear 17 is formed in a cylindrical shape. The pinion gear 17 is rotatably supported by the reel body 3. The pinion gear 17 is disposed on the radially outer side of the spool shaft 15. The pinion gear 17 rotates with respect to the spool shaft 15. The pinion gear 17 rotates around the spool axis X1.

[0040] As shown in FIG. 5, the speed reduction mechanism 19 reduces the rotation of the pinion gear 17 and transmits it to the oscillating mechanism 21. In FIG. 5, the gear teeth of each gear are omitted. Hatching is applied to the portions where the gears mesh with each other.

[0041] The speed reduction mechanism 19 is disposed between the pinion gear 17 and the oscillating mechanism 21. For example, the speed reduction mechanism 19 is disposed between the pinion gear 17 and the worm shaft gear 27. The speed reduction mechanism 19 has a first intermediate gear 31 and a second intermediate gear 33.

[0042] The first intermediate gear 31 is rotatably provided around a first axis A1 parallel to the spool axis X1. The first intermediate gear 31 is rotatably supported by the reel body 3. The first intermediate gear 31 has a first module M1. The first module M1 is calculated by dividing the diameter d1 of the pitch circle of the first intermediate gear 31 by the number of teeth z1 of the first intermediate gear 31. This calculation formula is expressed as "M1 = d1 / z1". In FIG. 5, the lead line indicating the number of teeth z1 of the first intermediate gear 31 is shown by a two-dot chain line.

[0043] The first intermediate gear 31 has a first large-diameter gear 31a and a first small-diameter gear 31b. The first large-diameter gear 31a meshes with the pinion gear 17. The rotation axis of the first large-diameter gear 31a is the first axis A1. The first small-diameter gear 31b is formed to have a smaller diameter than the first large-diameter gear 31a. The first small-diameter gear 31b is integrally formed with the first large-diameter gear 31a and rotates integrally with the first large-diameter gear 31a. The rotation axis of the first small-diameter gear 31b is the first axis A1.

[0044] The second intermediate gear 33 is rotatably provided around a second axis A2 parallel to the first axis A1. The second intermediate gear 33 is rotatably supported by the reel body 3. The second intermediate gear 33 has a second module M2. The second module M2 is calculated by dividing the diameter d2 of the pitch circle of the second intermediate gear 33 by the number of teeth z2 of the first intermediate gear 31. This calculation formula is expressed as "M2 = d2 / z2". In FIG. 5, the lead line indicating the number of teeth z2 of the second intermediate gear 33 is shown by a two-dot chain line.

[0045] The second intermediate gear 33 has a second large-diameter gear 33a and a second small-diameter gear 33b. The second large-diameter gear 33a meshes with the first small-diameter gear 31b. The rotation axis of the second large-diameter gear 33a is the second axis A2. The second small-diameter gear 33b is formed to have a smaller diameter than the second large-diameter gear 33a. The second small-diameter gear 33b is integrally formed with the second large-diameter gear 33a and rotates integrally with the second large-diameter gear 33a. The rotation axis of the second small-diameter gear 33b is the second axis A2. The second small-diameter gear 33b meshes with the worm shaft gear 27.

[0046] When the handle shaft 11 rotates by the rotational operation of the handle 5, the drive gear 13 rotates. The rotation of the drive gear 13 is transmitted to the pinion gear 17. The rotation of the pinion gear 17 is transmitted to the worm shaft gear 27 via the speed reduction mechanism 19 described above. The rotation of the worm shaft gear 27 is transmitted to the worm shaft 23. By the rotation of the worm shaft 23, the slider 25 and the spool shaft 15 move in the front-rear direction.

[0047] As shown in FIGS. 1 and 2, the rotor 9 is used for winding a fishing line around the spool 7. The rotor 9 is disposed at the front portion of the reel body 3. The rotor 9 is configured to be rotatable with respect to the reel body 3. The rotor 9 is disposed radially outside the pinion gear 17. The rotor 9 is mounted so as to be integrally rotatable with respect to the pinion gear 17.

[0048] When the handle shaft 11 rotates by the rotational operation of the handle 5, the drive gear 13 rotates. The rotation of the drive gear 13 is transmitted to the pinion gear 17. The rotor 9 rotates in conjunction with the rotation of the pinion gear 17.

[0049] The spinning reel 1 having the above configuration is configured as follows. The outer diameter R of the front flange 7b shown in FIGS. 3 and 6 is less than 60 mm. For example, the outer diameter R of the front flange 7b is preferably 35 mm or more and less than 60 mm. More preferably, the outer diameter R of the front flange 7b is 40 mm or more and less than 56 mm. The outer diameter R of the front flange 7b is defined by the outer peripheral surface 7b1 of the front flange 7b.

[0050] The winding pitch P of the fishing line is 1.0 mm or less. For example, the winding pitch P of the fishing line is preferably 0.4 mm or more and 1.0 mm or less. More desirably, the winding pitch P of the fishing line is preferably 0.55 mm or more and 0.90 mm or less. The winding pitch P of the fishing line is the axial interval between adjacent fishing lines on the spool body 7a.

[0051] Note that the thread winding pitch P is not constant depending on the structure of the oscillating mechanism 21. Therefore, here, the average thread winding pitch is used as the thread winding pitch P. The average thread winding pitch is a value (2S / N) obtained by dividing the reciprocating stroke distance (2S) by the number of rotations (N) of the rotor 9 while the spool 7 reciprocates back and forth once.

[0052] The value (S / (P·M)) obtained by dividing the stroke amount S of the spool shaft 15 by the smaller module M of the first module M1 of the first intermediate gear 31 and the second module M2 of the second intermediate gear 33 is 60 or more. The value (S / (P·M)) obtained by dividing the stroke amount S of the spool shaft 15 by the smaller module M of the first module M1 of the first intermediate gear 31 and the second module M2 of the second intermediate gear 33 is 150 or less. These relationships are expressed by the relational expression "60≦(S / (P·M))≦150".

[0053] As shown in FIG. 6, the stroke amount S of the spool shaft 15 is the amount by which the spool shaft 15 moves in the front-rear direction by the oscillating mechanism 21. The stroke amount S of the spool shaft 15 is preferably 12 mm or more and 25 mm or less. The stroke amount S of the spool shaft 15 is more preferably 13 mm or more and 23 mm or less.

[0054] FIG. 7 shows the above numerical values and a comprehensive evaluation of casting and reeling in a spinning reel 1 (adopted models 1 and 2) adopting the present invention, a spinning reel 1 (comparative model 3) in which the present invention can be adopted by changing the specifications of adopted models 1 and 2, and a conventional spinning reel (conventional models 1 to 3) having an intermediate gear or a gear corresponding to the intermediate gear, presented in a table.

[0055] The "Comprehensive Evaluation of Casting and Reeling" in Figure 7 is the result of sensory evaluation and ranking using the paired comparison test method for the quietness, sense of elongation, stability of winding, etc. when multiple testers performed casting and reeling (fishing line winding) for each of the "Size Categories A, B, C" of each spinning reel. Note that the symbol of the "Comprehensive Evaluation of Casting and Reeling" indicates the size category with an alphabet and the evaluation order with a numerical value.

[0056] For example, among the size category A, the comprehensive evaluation A1 of the adopted model 1 is higher than the comprehensive evaluation A2 of the conventional model 1. Among the size category B, the comprehensive evaluation B1 of the adopted model 2 is higher than the comprehensive evaluation B2 of the conventional model 2. Among the size category C, the comprehensive evaluation C1 of the comparison model 3 is higher than the comprehensive evaluation C2 of the conventional model 3. Thus, the comprehensive evaluations A1, B1, C1 of the adopted model 1, the adopted model 2, and the comparison model 3 have received higher evaluations compared to the comprehensive evaluations A2, B2, C2 of the conventional models in each of the size categories A, B, C.

[0057] The spinning reel 1 described above has the following characteristics. The spinning reel 1 is configured such that the value (S / (P·M)) obtained by dividing the stroke amount S of the spool shaft 15 by the winding pitch P of the fishing line and the module M of the intermediate gears 31, 33 is 60 or more. By designing the oscillating mechanism 21 and the spool 7 using this configuration, the problems of conventional spinning reels can be preferably solved.

[0058] In the spinning reel 1, the value (S / (P·M)) obtained by dividing the stroke amount S of the spool shaft 15 by the winding pitch P of the fishing line and the module M of the intermediate gears 31 and 33 is 150 or less. In the spinning reel 1, the winding pitch P is 1.0 mm or less. In the spinning reel 1, the outer diameter R of the front flange 7b is less 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 while decelerating the spool shaft 15 in the front-rear direction. Thereby, with a relatively simple structure, the problems of conventional spinning reels can be suitably solved.
