Description
[Technical Field]
[0001] The present invention relates to a spinning reel. [Background technology]
[0002] It is known that various problems occur in spinning reels at the dead points when the spool reciprocates back and forth, i.e., at the positions where the spool is located at the most forward and the most rearward positions. For example, when releasing the fishing line, the fishing lines come into contact with each other at the dead points, generating noise and increasing the resistance to releasing the fishing line. This is known to result in a decrease in casting distance. To solve the problems at the dead points, various techniques have been proposed, including increasing the diameter of the spool, extending the stroke of the spool's reciprocating movement (see, for example, Patent Document 1), and reducing the reel pitch of the fishing line (see, for example, Patent Document 2). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-106898 [Patent Document 2] Japanese Patent Application Publication No. 11-000086 Summary of the Invention [Problem to be solved by the invention]
[0004] In conventional technology, when the diameter of the spool is increased, the rotor that winds the fishing line onto the spool also becomes larger. To ensure sufficient space for the rotor to rotate, the distance from the fishing rod attachment leg to the housing must be increased. In other words, increasing the diameter of the spool results in an increase in the size of the spinning reel.
[0005] Furthermore, extending the stroke of the spool's reciprocating movement increases the length of the reciprocating mechanism in the front-to-rear direction. This means that the housing must be larger to accommodate the reciprocating mechanism. In other words, the increased stroke of the spool's reciprocating movement results in an increase in the size of the housing, and therefore the spinning reel itself.
[0006] On the other hand, compared to the aforementioned technology, winding the fishing line at a finer pitch is effective in preventing the spinning reel from becoming larger. However, the finer the fishing line winding pitch, the more complex the structure, such as a reduction mechanism with a large reduction ratio, and the more difficult to manufacture parts, such as a worm shaft with a thin groove between the grooves, are required. In other words, problems arise such as the spinning reel's structure becoming more complex and its manufacturing costs increasing.
[0007] Furthermore, since the thickness of the fishing line used varies depending on the size of the spool, it is difficult to set an appropriate fishing line winding pitch depending on the thickness of the fishing line.
[0008] Thus, the prior art for solving the problem of dead points has various problems as described above.
[0009] Therefore, the present invention proposes a basic structure that is useful for designing a reciprocating mechanism and a spool. That is, in the present invention, reference values are set when designing a reciprocating mechanism and a spool, and the reciprocating mechanism and the spool are designed using these reference values.
[0010] SUMMARY OF THE INVENTION An object of the present invention is to propose a spinning reel having a basic structure that can satisfactorily solve the problems of conventional spinning reels. [Means for solving the problem]
[0011] A spinning reel according to one aspect of the present invention comprises a reel body, a spool shaft, and a spool. The spool shaft is supported on the reel body so as to be reciprocatable in the front-to-rear direction. The spool is connected to the spool shaft. The spool has a bobbin body around which fishing line is wound and a front flange extending radially outward from the front end of the bobbin body. The outer diameter of the front flange is less than 60 mm. The stroke of the spool shaft divided by the fishing line winding pitch is 20 or greater.
[0012] In this spinning reel, the front flange has an outer diameter of less than 60 mm. The value obtained by dividing the stroke of the spool shaft by the fishing line winding pitch is 20 or greater. This configuration allows for an advantageous increase in the amount of fishing line wound in the front-to-rear direction on the spool in a spinning reel with a front flange having an outer diameter of less than 60 mm. By designing a reciprocating mechanism and spool using this configuration, the problems associated with conventional spinning reels can be advantageously solved.
[0013] In a 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 is equal to or less than 30. By designing the reciprocating mechanism and spool using this configuration, the problems of conventional spinning reels can be effectively solved.
[0014] In a spinning reel according to another aspect of the present invention, it is preferable that the value obtained by dividing the stroke of the spool shaft by the winding pitch of the fishing line and multiplying the result by the outer diameter of the front flange is equal to or greater than 950 and equal to or less than 1500. In this configuration, in a spinning reel whose front flange has an outer diameter of less than 60 mm, the problems of conventional spinning reels can be solved by designing the reciprocating mechanism and spool according to the outer diameter of the front flange.
[0015] In a spinning reel according to another aspect of the present invention, the winding pitch is preferably 1.0 mm or less. By designing the reciprocating mechanism and spool using this configuration, the problems of conventional spinning reels can be effectively solved.
[0016] A spinning reel according to another aspect of the present invention preferably further includes a handle, a pinion gear, a first intermediate gear, a second intermediate gear, and a reciprocating mechanism. The handle is rotatably supported on the reel body. The pinion gear is rotatably supported on the reel body. Rotation of the handle is transmitted to the pinion gear.
[0017] The first intermediate gear is rotatable about a first axis parallel to the spool shaft and includes a first large-diameter gear that meshes with the pinion gear and a first small-diameter gear that has a smaller diameter than the first large-diameter gear and rotates integrally with the first large-diameter gear.
[0018] The second intermediate gear is rotatable 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 has a smaller diameter than the second large diameter gear and rotates integrally with the second large diameter gear.
[0019] The reciprocating mechanism reciprocates the spool shaft in the front-to-rear direction and includes a driven gear that meshes with the second small diameter gear and a worm shaft that rotates integrally with the driven gear.
[0020] This configuration allows the fishing line to be wound onto the spool while slowing down the forward and backward movement of the spool shaft, thereby effectively solving the problems associated with conventional spinning reels with a relatively simple structure. [Effects of the Invention]
[0021] The spinning reel of the present invention can effectively solve the problems of conventional spinning reels. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0023] As shown in Figure 1, a spinning reel 1 embodying one embodiment of the present invention includes a reel body 3, a handle 5, a spool 7, and a rotor 9. As shown in Figure 2, the spinning reel 1 further includes a handle shaft 11, a drive gear 13, a spool shaft 15, a pinion gear 17, a speed reduction mechanism 19, and an oscillating mechanism 21 (an example of a reciprocating mechanism). Note that Figure 2 shows the spinning reel 1 shown in Figure 1 with the side cover 1a and body guard 1b removed.
[0024] As shown in FIG. 1 , the handle 5 is rotatably supported on the reel body 3. In this embodiment, the handle 5 is disposed on the left side of the reel body 3. The handle 5 may also be disposed on the right side of the reel body 3. The handle 5 is attached to a handle shaft 11.
[0025] 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 a pinion gear 17.
[0026] Fishing line is wound around the spool 7. As shown in FIG. 2, the spool 7 is configured to be movable back and forth relative 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).
[0027] The spool 7 has a central axis X2. When the spool 7 is connected to the spool shaft 15, the central axis X2 of the spool 7 is coaxial with a spool axis X1, which will be described later.
[0028] As shown in FIG. 3, the spool 7 has a bobbin trunk 7a, a front flange 7b, and a skirt portion 7c. Fishing line is wound around the outer periphery of the bobbin trunk 7a. The bobbin trunk 7a is formed in a cylindrical shape. The front flange 7b extends radially outward from the front end of the bobbin trunk 7a. The front flange 7b is formed integrally with the bobbin trunk 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 outward of the front flange 7b (see FIG. 2). The spool collar 10 covers the outer peripheral surface 7b1 of the front flange 7b.
[0029] The skirt portion 7c is formed integrally with the rear end of the bobbin trunk 7a. The skirt portion 7c has a rear flange 7c1 and a tubular portion 7c2. The rear flange 7c1 extends radially outward from the rear end of the bobbin trunk 7a. The rear flange 7c1 is formed integrally with the bobbin trunk 7a. The rear flange 7c1 is formed in a disk shape. The tubular portion 7c2 extends rearward from the outer periphery of the rear flange 7c1. The tubular portion 7c2 is formed integrally with the rear flange 7c1. The tubular portion 7c2 is formed in a cylindrical shape.
[0030] As shown in Figure 2, the spool shaft 15 is supported so as to be able to move back and forth in the front-to-rear direction relative to the reel body 3. The spool shaft 15 is inserted into the inner periphery of a cylindrical pinion gear 17. The spool shaft 15 moves back and forth in the front-to-rear direction relative to the reel body 3 by operation of the oscillating mechanism 21.
[0031] The spool shaft 15 has a spool axis X1. The front-rear direction and the axial direction are directions in which the spool axis X1 extends. The radial direction is a direction away from the spool axis X1. The circumferential direction and the rotational direction are directions around the spool axis X1.
[0032] The oscillating mechanism 21 moves the spool shaft 15 in the front-to-rear direction. For example, the oscillating mechanism 21 moves the spool shaft 15 in the front-to-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.
[0033] As shown in Figures 2 and 4, the oscillating mechanism 21 has 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-to-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.
[0034] The worm shaft 23 has a shaft body 23a and a groove 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 23b is provided on the outer peripheral surface of the shaft body 23a. A pawl member 26, which will be described later, engages with the groove 23b.
[0035] 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 back and forth as the worm shaft 23 rotates.
[0036] For example, as shown in Figure 4, a pawl member 26 is attached to the slider 25. The pawl member 26 is rotatably attached to the spool shaft 15 and the slider 25. The pawl member 26 engages with the groove portion 23b of the worm shaft 23. As a result, when the worm shaft 23 rotates, the pawl member 26 moves along the groove portion 23b of the worm shaft 23. As a result, the slider 25 moves in the front-rear direction.
[0037] 2 and 4, the worm shaft gear 27 is attached to the worm shaft 23. For example, the worm shaft gear 27 has a rotation axis W2. The worm shaft gear 27 is attached to the worm shaft 23 so 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.
[0038] 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 reduction mechanism 19.
[0039] 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.
[0040] As shown in Figure 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 radially outward of the spool shaft 15. The pinion gear 17 rotates relative to the spool shaft 15. The pinion gear 17 rotates around the spool axis X1.
[0041] 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, and the portions where the gears mesh with each other are hatched.
[0042] The reduction mechanism 19 is disposed between the pinion gear 17 and the oscillating mechanism 21. For example, the reduction mechanism 19 is disposed between the pinion gear 17 and the worm shaft gear 27.
[0043] The reduction gear mechanism 19 has a first intermediate gear 31 and a second intermediate gear 33. The first intermediate gear 31 is rotatably mounted about 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 large diameter gear 31a and a first small diameter gear 31b.
[0044] 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 formed integrally 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.
[0045] The second intermediate gear 33 is rotatably provided about 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 large diameter gear 33a and a second small diameter gear 33b.
[0046] 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 formed integrally 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.
[0047] When the handle shaft 11 is rotated by rotating 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 reduction mechanism 19 described above. The rotation of the worm shaft gear 27 is transmitted to the worm shaft 23. The rotation of the worm shaft 23 moves the slider 25 and the spool shaft 15 in the front-to-rear direction.
[0048] As shown in Figures 1 and 2, the rotor 9 is used to wind fishing line onto the spool 7. The rotor 9 is located at the front of the reel body 3. The rotor 9 is configured to be rotatable relative to the reel body 3. The rotor 9 is located radially outward of the pinion gear 17. The rotor 9 is attached to the pinion gear 17 so as to be rotatable integrally with it.
[0049] When the handle shaft 11 is rotated by rotating 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.
[0050] The spinning reel 1 having the above configuration is configured as follows: The outer diameter R of the front flange 7b shown in Figures 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.
[0051] The fishing line is wound at a pitch P of 1.0 mm or less. For example, the fishing line is preferably wound at a pitch P of 0.4 mm or more and 1.0 mm or less. More preferably, the fishing line is wound at a pitch P of 0.55 mm or more and 0.90 mm or less. The fishing line is wound at a pitch P that is the axial distance between adjacent pieces of fishing line on the bobbin trunk 7a.
[0052] The line winding pitch P is not constant depending on the structure of the oscillating mechanism 21. For this reason, here, the average line winding pitch is used as the line winding pitch P. The average line winding pitch is the value (2S / N) obtained by dividing the reciprocating stroke distance (2S) by the number of rotations (N) of the rotor 9 during one reciprocating movement of the spool 7 back and forth.
[0053] The value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the fishing line winding pitch P is equal to or greater than 20. The value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the fishing line winding pitch P is equal to or less than 30. In other words, the value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the fishing line winding pitch P is equal to or greater than 20 and equal to or less than 30. This relationship is expressed by the relational expression "20≦(S / P)≦30".
[0054] 6, the stroke amount S of the spool shaft 15 is the amount of movement of the spool shaft 15 in the front-to-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.
[0055] The value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the fishing line winding pitch P and multiplying this by the outer diameter R of the front flange 7b ((S / P) x R) is 950 or more and 1500 or less. This relationship is expressed by the relational expression "950≦{(S / P) x R}≦1500".
[0056] Figure 7 shows a table of the above numerical values and an overall evaluation of casting and reeling for spinning reel 1 incorporating the present invention (adopting models 1 and 2), spinning reel 1 in which the present invention can be adopted by changing the specifications of adopting models 1 and 2 (comparison model 3), and conventional spinning reels (conventional models 1 to 6).
[0057] The "Overall Rating of Casting and Reeling" in Figure 7 is a ranking of the results of a paired comparison test conducted by multiple testers who evaluated quietness, feel of extension, winding stability, etc. when casting and reeling (winding in fishing line) each spinning reel in "size categories A, B, C." The letters in the "Overall Rating of Casting and Reeling" section indicate the size category, and the numbers indicate the order of evaluation.
[0058] For example, within size category A, the overall rating A1 of adopted model 1 is the highest compared to the overall ratings A2 and A3 of conventional models 1 and 4. Within size category B, the overall rating B1 of adopted model 2 is the highest compared to the overall ratings B2 and B3 of conventional models 2 and 5. Within size category C, the overall rating C1 of comparison model 3 is the highest compared to the overall ratings C2 and C3 of conventional models 3 and 6. In this way, the overall ratings A1, B1, and C1 of adopted model 1, adopted model 2, and comparison model 3 are the highest among the size categories A, B, and C.
[0059] The spinning reel 1 described above has the following features: In a spinning reel 1 in which the front flange 7b has an outer diameter R of less than 60 mm, the value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the fishing line winding pitch P is 20 or greater. By designing the oscillating mechanism 21 and spool 7 using this configuration, the problems of conventional spinning reels can be effectively solved.
[0060] In a spinning reel 1 in which the front flange 7b has an outer diameter R of less than 60 mm, the problem of conventional spinning reels can be solved by setting the value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the winding pitch P of the fishing line to 30 or less.
[0061] In a spinning reel 1 in which the front flange 7b has an outer diameter R of less than 60 mm, the value (S / P) obtained by dividing the stroke amount S of the spool shaft 15 by the fishing line winding pitch P, multiplied by the outer diameter R of the front flange 7b ((S / P) x R) is 950 or greater and 1500 or less. Thus, by designing the oscillating mechanism 21 and spool 7 according to the outer diameter R of the front flange 7b, the problems of conventional spinning reels can be resolved effectively.
[0062] In a spinning reel 1 in which the front flange 7b has an outer diameter R of less than 60 mm, the problems of conventional spinning reels can be suitably solved by setting the winding pitch P to 1.0 mm or less.
[0063] The spinning reel 1, in which the front flange 7b has an outer diameter R of less than 60 mm, has the first intermediate gear 31 and second intermediate gear 33, which allows the fishing line to be wound onto the bobbin trunk 7a while slowing down the forward and backward movement of the spool shaft 15. This allows the problems of conventional spinning reels to be solved with a relatively simple structure. [Industrial Applicability]
