Description

[Technical field]

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

[0002] Fishing spinning reels are equipped with a spool shaft that moves back and forth in response to the rotation of the handle, and a spool is attached to the spool shaft (see Patent Document 1). The spool is configured to be rotatable relative to the spool shaft, and the spool shaft and the spool are equipped with a spool sounding mechanism that notifies the user of the relative rotation. The spool sounding mechanism is composed of a sounding body provided on the spool side and a sounding member provided on the spool shaft side.

[0003] As shown in Patent Document 1, the sound-producing body is, for example, a ratchet groove formed on the inner peripheral surface of the spool. The sound-producing member is, for example, a click pawl spring having a protrusion that protrudes radially outward. When the spool rotates in response to the reeling out of the fishing line during actual fishing, the protrusion of the click pawl spring engages with the convex and concave portions of the ratchet groove, generating a clicking sound. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2005-073670 A Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, the concave portion of the ratchet groove is semicircular, so the deformation of the click pawl spring increases with respect to the rotational movement distance of the spool when the fishing line is released, and the click pawl spring is more likely to experience elastic resistance during drag operation. This causes a problem that smooth drag operation is hindered. In addition, with the conventional structure, each sliding part is more likely to wear out, which causes a problem of reduced noise generation.

[0006] The present invention was created to solve such problems, and its object is to provide a fishing spinning reel that can reduce resistance during drag operation while preventing a decrease in sound generation. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a fishing spinning reel that includes a spool that is rotatably and frictionally coupled to the tip of a spool shaft provided in a reel body by a drag device, and that includes a spool sound generating mechanism that is configured by engaging a sound generating member provided on the spool shaft with a sound generating body formed in a convex and concave shape on the inner peripheral surface of the spool, The sounding body includes an inner peripheral wall, an outer peripheral wall disposed outside the inner peripheral wall, and a ratchet groove provided on an inner surface of the outer peripheral wall, and the ratchet groove has convex portions and concave portions alternately formed in the circumferential direction, the concave portion has a first apex which is a boundary between one of the adjacent convex portions, a first surface which is continuous with the first apex and is concave in the radially outward direction, a second surface which is continuous with the first surface, and a second apex which is continuous with the second surface and is a boundary between the concave portion and the other of the adjacent convex portions, the second surface is formed on the opposite side to the direction in which the spool rotates when the fishing line is reeled out, a distance L2 from the second apex to the deepest part of the concave portion is longer than a distance L1 from the first apex to the deepest part of the concave portion, and the sound-generating member protrudes in the radially outward direction. and engages with the ratchet groove. A click spring having a plate shape and a protruding portion is provided. The click pawl spring is disposed between the inner peripheral wall and the outer peripheral wall in the circumferential direction, and an acoustic space is formed by the protruding portion of the click pawl spring and the recessed portion. It is characterized by:

[0008] According to the present invention, since the distance L2 is longer than the distance L1, the sound-generating member moves smoothly from the second surface to the second apex. This reduces the resistance during drag operation. In addition, by providing a depth in the radially outward direction on the first surface side, the acoustic space required for sound generation is secured. In addition, since the sound-generating member moves smoothly on the second surface side, wear of each sliding portion can be prevented. This makes it possible to prevent a decrease in sound generation. In addition, according to the present invention, the provision of the protruding portion can further improve sound generation. In addition, it is preferable that a plate-shaped support portion constituting the sound-producing member is sandwiched between a washer inserted onto the spool shaft and a step portion of the spool shaft, and that the click claw spring is supported by the support portion.

[0009] In addition, it is preferable that the first surface is a curved surface and the second surface is an inclined surface. According to the present invention, the sound generating member can move more smoothly from the second surface to the second top portion. Effect of the Invention

[0011] According to the fishing spinning reel of the present invention, it is possible to reduce resistance during drag operation while preventing a decrease in sound generation. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] A spool of a fishing spinning reel according to one embodiment of the present invention will be described below with reference to the drawings as appropriate. In the description of the embodiment, "up and down" and "front and back" refer to the directions shown in Fig. 1, and "left and right" refer to the directions shown in Fig. 2.

[0014] As shown in FIG. 1, a fishing spinning reel R1 mainly comprises a reel body 1 having legs 1A for attachment to a fishing rod (not shown), a rotor 2 rotatably mounted in front of the reel body 1, and a spool 10 movable back and forth in synchronization with the rotational motion of the rotor 2.

[0015] A handle shaft 3 is rotatably supported by the reel body 1 via a bearing (not shown), and a handle 4 for use in winding is attached to the protruding end of the handle shaft 3. A shaft cylinder is fixed to the handle shaft 3 in a manner that prevents it from rotating. A drive gear 6 having internal teeth for winding and driving the rotor 2 is formed integrally with this shaft cylinder. This drive gear 6 extends in a direction perpendicular to the handle shaft 3 and meshes with a pinion gear 7a of a drive shaft cylinder 7 having a hollow portion extending axially therein.

[0016] The drive shaft tube 7 is rotatably supported on the reel body 1 via bearings, and a spool shaft 8 extending in a direction perpendicular to the handle shaft 3 and having a spool 10 attached to its tip end is inserted into its hollow portion so as to be movable in the axial direction.

[0017] A known oscillating mechanism 9 for moving the spool shaft 8 back and forth is provided at the rear end of the spool shaft 8.

[0018] The drive shaft cylinder 7 extends toward the spool 10, and the rotor 2 is attached to its front end via a nut 7b (see FIG. 2). Note that the drive shaft cylinder 7 is restricted from rotating in the reverse direction (rotating in the fishing line releasing direction) by a one-way clutch (not shown).

[0019] The rotor 2 includes a cylindrical portion 2a (see FIG. 2) located within the skirt portion 10a of the spool 10, and a pair of arm portions 2b, 2c. At the front end of each arm 2b, 2c, bail support members 2d, 2e are supported so as to be rotatable between a line winding position and a line releasing position, and a bail 2f for picking up the released fishing line is disposed between these bail support members 2d, 2e. One base end of the bail 2f is attached to a line roller 2g that is integrally provided with the bail support member 2d, and the other base end is attached to the bail support member 2e.

[0020] 1, the spool 10 has a cylindrical shape and is provided with a fishing line winding body 10c around which a fishing line (not shown) is wound between a skirt portion 10a and a front flange 10b. The details of the spool 10 will be described later.

[0021] In such a fishing spinning reel R1, when the handle 4 is operated for reeling, the rotor 2 is rotated via the drive gear 6 and the pinion gear 7a, and the spool 10 is moved back and forth via the pinion gear 7a and the oscillating mechanism 9. As a result, the fishing line (not shown) is evenly wound around the fishing line winding trunk 10c of the spool 10 via the line roller 2g.

[0022] Next, a detailed description will be given of the spool 10. As shown in Figures 2 and 4, the spool 10 includes a spool body 11 and a sound generating body 20 provided separately from the spool body 11. Note that, although the spool body 11 and the sound generating body 20 are separate bodies in this embodiment, they may also be integrated. As shown in Fig. 2, the spool body 11 is attached to the spool shaft 8 via a retaining member 30. The spool shaft 8 has a body portion 8a having a circular cross section and a tip portion 8b having a substantially oval cross section. The outer circumferential surface of the tip portion 8b has a straight portion and a curved portion. A step portion 8c is formed at the boundary between the body portion 8a and the tip portion 8b.

[0023] The holding member 30 is attached to the tip portion 8b. A through hole 8d is formed in the tip portion 8b, penetrating in the direction perpendicular to the axis. A locking pin 33 for locking the holding member 30 is inserted into the through hole 8d.

[0024] The holding member 30 is cylindrical and has a base 31a and a flange 31b through which the tip 8b of the spool shaft 8 is inserted. The base 31a has a circular inner periphery 31c (see FIG. 3) having an inner diameter that is fitted to the curved portion of the tip 8b having a substantially oval cross section, and an inner periphery 31d (see FIG. 2) having a substantially oval cross section that is formed in front of the circular inner periphery 31c and is fitted to both the straight and curved portions of the tip 8b having a substantially oval cross section. The inner periphery 31d has a through hole 32 through which a locking pin 33 is inserted. The through hole 32 is connected to the through hole 8d of the tip 8b of the spool shaft 8. The holding member 30 is attached so as to be immovable in the axial direction and imrotatable in the axial direction by locking the locking pin 33 to the through hole 8d through the through hole 32.

[0025] A rear bearing 18b made of a bearing is fitted onto the outer surface of the rear part of the base 31a. The rear bearing 18b is held in place by a washer 34 arranged on the rear end surface of the base 31a. A support part 41 constituting a sound-producing member 40 is sandwiched between the washer 34 and the step part 8c of the spool shaft 8. The sound-producing member 40 includes the support part 41 made of metal and a click pawl spring 42 supported by the support part 41.

[0026] As shown in FIG. 3, the support portion 41 has four hook portions 41a extending on both the left and right sides. The click claw spring 42 is a thin plate-like metal member having elasticity. The click claw spring 42 has a generally U-shape as a whole when viewed from the front, and has a protruding portion 44 that protrudes to the left (diametrically outward). The tip of the protruding portion 44 has a curved surface. The protruding portion 44 is disposed between the left hook portions 41a, 41a. In addition, both ends 45, 45 of the click claw spring 42 are engaged with the right hook portions 41a, 41a.

[0027] As shown in FIG. 2, a support wall 12 and a middle wall 13 are formed on the inside of the spool body 11 as a structure for holding the spool body 11 on the holding member 30. The support wall 12 is substantially disk-shaped and extends from the inner surface of the fishing line winding body 10c toward the inside in the radial direction. The middle wall 13 is cylindrical and extends from the extended end of the support wall 12 toward the rear. A sounding body 20 is attached to the rear of the middle wall 13 by a screw structure described later. In addition, a cylindrical drag housing portion 18 (see FIG. 4) is formed on the front side of the support wall 12 to house a drag device T (see FIG. 1). The drag device T is a device that applies a braking force to the fishing line that is pulled out when a fish is hooked during actual fishing. By adjusting the drag knob Ta (see FIG. 1) of the drag device T, a desired braking force can be applied to the spool 10 rotatably held on the spool shaft 8.

[0028] The middle wall 13 is formed concentrically with the central axis O1 of the spool body 11, as shown in FIG. 4, and on its inside is formed an insertion hole 19 through which a part of the retaining member 30 and the tip portion 8b of the spool shaft 8 are inserted, as shown in FIG. 2. 2, the middle wall 13 has a large diameter portion 13a continuing to the support wall 12, and a small diameter portion 14 continuing to the rear side of the large diameter portion 13a. A step portion 16 (see FIG. 4) is formed on the outer surface of the middle wall 13 at the boundary between the large diameter portion 13a and the small diameter portion 14.

[0029] A ring-shaped partition wall 15 is formed on the inner peripheral surface of the large diameter portion 13a to divide the inner peripheral surface of the large diameter portion 13a into front and rear portions. A front bearing 18a made of a bearing is fitted into the inner peripheral surface of the large diameter portion 13a on the front side of the partition wall 15. The front bearing 18a is held in place by a retaining member 13b engaged with the inner peripheral surface of the large diameter portion 13a and the partition wall 15. An inner ring of the front bearing 18a is attached to the front outer peripheral surface of the base portion 31a of the holding member 30. The rear surface of the partition wall 15 abuts against the front surface of the flange portion 31b of the holding member 30 via two washers 35.

[0030] The front bearing 18a and the rear bearing 18b are arranged side by side in the front-rear direction between the holding member 30 and the middle wall 13. As a result, the spool body 11 is stably held at the tip end 8b of the spool shaft 8 by the two front and rear bearings 18a, 18b.

[0031] As shown in Figs. 2 and 4, the small diameter portion 14 is a portion to which the sounding body 20 is attached. A male screw portion 14a that functions as a screw portion of a screw-fit structure is formed on the outer peripheral surface of the rear portion of the small diameter portion 14. The male screw portion 14a is formed concentrically with the insertion hole 19 when viewed from the axial direction of the insertion hole 19. In other words, the male screw portion 14a is arranged concentrically with a circle centered on the central axis O1 of the spool. In this embodiment, the sounding body 20 is screwed into the small diameter portion 14, but it may be connected by press-fitting. On the other hand, an outer ring of the rear bearing 18b that is fitted on the holding member 30 side is attached to the inner peripheral surface of the rear portion of the small diameter portion 14.

[0032] The sounding body 20 is a member that is attached to the middle wall 13 of the spool body 11 by a screw structure, and has a cylindrical shape. The sounding body 20 is entirely made of resin, for example, fiber-reinforced resin containing carbon fiber, glass fiber, or the like. In other words, it has a hardness difference with respect to the click pawl spring 42 that serves as the sounding member. The sounding body 20 and the sounding member 40 (click pawl spring 42) engage with each other to form a spool sounding mechanism.

[0033] 2 and 4, the sounding body 20 includes a ring-shaped bottom wall 21, an inner circumferential wall 22 extending rearward from a radially inner portion of the bottom wall 21, and an outer circumferential wall 23 disposed radially outward from the inner circumferential wall 22 with a gap therebetween and extending rearward from a radially outer portion of the bottom wall 21. The sounding body 20 includes a recessed portion (annular recessed space portion) 25 surrounded by the bottom wall 21, the inner circumferential wall 22, and the outer circumferential wall 23. The recessed portion 25 opens annularly toward the rear, as shown in FIG.

[0034] 2 and 4, a female thread portion 22a that functions as a screw thread portion of a screw structure is formed on the entire inner peripheral surface of the inner peripheral wall 22. The female thread portion 22a can be screwed into the male thread portion 14a of the middle wall 13.

[0035] As shown in FIG. 3, a ratchet groove 24 is formed on the inner peripheral surface of the outer peripheral wall 23. The protruding portion 44 of the click pawl spring 42 resiliently abuts against the ratchet groove 24. As shown in FIG. 5, the ratchet groove 24 is composed of convex portions 51 and concave portions 61 formed alternately on the entire inner peripheral surface of the outer peripheral wall 23. The concave portions 61 are formed to be concave in the radially outward direction. The portions formed between the adjacent concave portions 61, 61 are the convex portions 51. The concave portions 61 have a first surface 62 and a second surface 63. A corner portion that is a boundary between the convex portion 51 on one side of the concave portion 61 is defined as a first apex 64. A corner portion that is a boundary between the convex portion 51 on the other side of the concave portion 61 is defined as a second apex 65. In addition, the position of the concave portion 61 that is farthest from the central axis O1 of the spool (see FIG. 4) is defined as a deepest portion 66. In addition, the boundary between the first surface 62 and the second surface 63 is indicated by an imaginary line 67.

[0036] One circumferential side of the deepest part 66 is designated as direction P, and the other side is designated as direction Q. Direction P refers to the direction in which the spool 10 rotates when a fish is hooked and the fishing line is released during actual fishing. The second surface 63 is formed in the recess 61 on the side in direction Q (opposite to the direction in which the spool 10 rotates when the fishing line is released).

[0037] The first surface 62 is a curved surface (arcuate surface) that continues from the first apex 64 to the imaginary line 67. On the other hand, the second surface 63 is an inclined surface that continues from the imaginary line 67 to the second apex 65. A distance L2 from the second apex 65 to the deepest part 66 is longer than a distance L1 from the first apex 64 to the deepest part 66. In other words, the deepest part 66 is located closer to the first apex 64 (toward the P direction) than the center of the width direction of the recess 61. This makes the shape of the recess 61 asymmetrical.

[0038] In addition, on the premise that the above-mentioned distances L1 and L2 are satisfied, the first surface 62 may be an inclined surface, and the second surface 63 may be a curved surface (an arc-shaped surface). In addition, on the premise that the above-mentioned distances L1 and L2 are satisfied, both the first surface 62 and the second surface 63 may be curved surfaces, or both may be inclined surfaces.

[0039] As shown in Figures 2 and 4, the rear end of the outer peripheral wall 23 protrudes rearward from the rear end of the inner peripheral wall 22, and is disposed in the inner region of the skirt portion 10a, utilizing the space formed between the outer peripheral wall 23 and the cylindrical portion 2a of the rear rotor 2. As a result, the region of the recessed portion 25 surrounded by the outer peripheral wall 23 expands toward the rear. This contributes to improving the sound-producing effect. In addition, the rear end of the outer peripheral wall 23 expands in diameter in a tapered shape, and functions as a guide for the click pawl spring 42 during assembly.

[0040] As shown in Fig. 4, a gap S1 is formed between the outer peripheral wall 23 and the fishing line winding trunk portion 10c and the skirt portion 10a (line stopper portion 10s) of the spool body 11 on the radially outer side. The gap S1 functions as a finger insertion portion when attaching and detaching the sound generating body 20 to and from the spool body 11. The gap S1 also makes it easier for the sound of the sound generating body 20 to resonate.

[0041] When attaching the sounding body 20 to the spool body 11, the sounding body 20 is inserted into the inside of the skirt portion 10a from the rear of the spool body 11, the inner peripheral wall 22 of the sounding body 20 is aligned with the small diameter portion 14 of the middle wall 13 of the spool body 11, and the sounding body 20 is rotated in the screwing direction. As a result, the female thread portion 22a is screwed into the male thread portion 14a, and the sounding body 20 is attached to the spool body 11 (middle wall 13). The bottom wall 21 of the sounding body 20 is abutted against the step portion 16 of the middle wall 13 by screwing, and the sounding body 20 is pressed and fixed to the middle wall 13 by this abutment. Since the bottom wall 21 of the sounding body 20 abuts against the step portion 16, damage due to over-tightening of the sounding body 20 can be prevented. After attachment, the sounding body 20 can be removed from the spool body 11 by releasing the screwing.

[0042] When the sound producing body 20 is attached to the spool body 11, as shown in FIG. 2, the rear bearing 18b, the sound producing body 20, and the outer diameter portion of the spool body 11 (the fishing line winding body portion 10c and the skirt portion 10a) are arranged in this order from the axis of the insertion hole 19 (the central axis O1 of the spool body 11) toward the radially outward direction.

[0043] Next, the operation of the spool sound generating mechanism will be described while comparing the comparative example and the example. FIG. 6 is a comparison table comparing the operation state of the comparative example and the example for the spool sound generating mechanism. The upper part of FIG. 6 shows the comparative example (the form of Patent Document 1), and the lower part shows the example (the embodiment of the present invention). Each figure shows the engagement state when the spool rotation angle increases by 1° from left to right. The deformation amount D shown in the figure indicates the deformation amount of the protrusion 44. The deformation amount D is based on the position of the tip of the protrusion 44 when the spool rotation angle is 0°, and indicates the distance from the reference to the tip of the protrusion 44 (the movement distance in the radial outward direction). When the fishing line is reeled out, the click pawl spring 42 does not rotate, and the sound generating body 20 (spool 10) rotates to generate a sound.

[0044] FIG. 7 is an enlarged view showing a comparative example when the spool rotation angle is 0°. FIG. 8 is an enlarged view showing a comparative example when the spool rotation angle is 4°. As shown in FIGS. 7 and 8, the ratchet groove of the comparative example is composed of convex portions 71 and concave portions 81 formed alternately in the circumferential direction of the inner peripheral surface. The shape of the concave portions 81 is symmetrical and has a semicircular curved surface. The boundaries between the concave portions 81 and the adjacent convex portions 71 are defined as a first apex 84 and a second apex 85, respectively. The center line of the concave portions 81 in the width direction is defined as a center line V1.

[0045] As shown in FIG. 7, when the spool rotation angle of the comparative example is 0°, the center line 44a, which is the center line in the width direction of the protrusion 44 of the click claw spring 42, is located on the center line V1 of the recess 81. At this time, the protrusion 44 is in a state of being deeply fitted into the recess 81. In addition, since the curvature of the recess 81 is larger than the curvature of the tip of the protrusion 44, the deepest part 86 of the recess 81 does not contact the protrusion 44, and the protrusion 44 abuts (is in point contact with) both the first apex 84 and the second apex 85. As shown in FIG. 6, when the spool rotation angle is 1 to 3°, the protrusion 44 slides while contacting the second apex 85. Then, as shown in FIG. 8, when the spool rotation angle is 4°, the center line 44a of the protrusion 44 is located near the second apex 85 of the recess 81, and the deformation amount D is 0.25 mm.

[0046] FIG. 9 is an enlarged view showing an embodiment when the spool rotation angle is 0°. FIG. 10 is an enlarged view showing an embodiment when the spool rotation angle is 4°. As shown in FIG. 9 and FIG. 10, in the embodiment, the shape of the recess 61 is asymmetrical with the deepest part 66 being eccentric as described above, and includes a first surface 62 which is a curved surface and a second surface 63 which is an inclined surface. The radius of curvature of the first surface 62 is smaller than the radius of curvature of the recess 81 of the comparative example shown in FIG. 7. The depth dimension of the deepest part 66 of the recess 61 is the same or approximately the same as the depth dimension of the deepest part 86 of the recess 81. The center line of the recess 61 in the width direction is defined as center line V2.

[0047] When the spool rotation angle of the embodiment is 0°, the center line 44a of the protrusion 44 of the click claw spring 42 is located on the center line V2 of the recess 61. At this time, the protrusion 44 is in a state of being deeply fitted into the recess 81. At this time, the protrusion 44 does not contact the deepest part 66 and the second apex 65, but abuts against the first apex 64 and the second surface 63. The center line 44a of the protrusion 44 is located on the Q direction side of the deepest part 66. As shown in FIG. 6, when the spool rotation angle is 1 to 3°, the protrusion 44 slides along the second surface 63. Then, as shown in FIG. 10, when the spool rotation angle is 4°, the center line 44a of the protrusion 44 is located near the second apex 65 of the recess 61, and the deformation amount D is 0.19 mm. Although specific illustration is omitted, in the embodiment, when the spool rotation angle is 7°, the deformation amount D is 0.25 mm. When the spool 10 further rotates and the protrusion 44 drops from the first apex 64 of the adjacent recess 61 into the recess 61 at 0° (when part of the protrusion 44 hits the second surface 63), a clicking sound is generated.

[0048] According to the present embodiment described above, since the distance L2 of the recess 61 is longer than the distance L1, the protrusion 44 of the click pawl spring 42 moves smoothly from the second surface 63 on the Q direction side to the second apex 65. In other words, the radially outward movement distance of the protrusion 44 with respect to the spool rotation angle is shorter than in the comparative example, and the deformation amount of the click pawl spring 42 is also smaller. This makes it possible to reduce resistance during drag operation.

[0049] Also, by providing a depth in the radially outward direction on the first surface 62 side, an acoustic space (space surrounded by the recess 61 and the protrusion 44) required for sound generation can be secured. This makes it possible to reduce resistance during drag operation while producing a good sound with a sense of precision. Also, since the protrusion 44 of the click pawl spring 42 moves smoothly on the second surface 63 side, wear of each sliding part, particularly wear of the second surface 63 and the second apex 65, can be prevented. This makes it possible to prevent wear of the ratchet groove 24 while preventing a decrease in sound generation.

[0050] In addition, the second surface 63 may be a curved surface, but by making it an inclined surface, the protrusion 44 of the click pawl spring 42 can move more smoothly from the second surface 63 to the second apex 65.

[0051] Furthermore, by providing the click pawl spring 42 having the protruding portion 44 protruding in the radially outward direction, it becomes easier to engage with the ratchet groove 24, and sound generation can be further improved. Furthermore, on the premise that the distances L1 and L2 are satisfied, the radius of curvature of the first surface 62 and the inclination angle of the second surface 63 can be set appropriately. As a result, the number of pitches (the number of recesses 61) of the ratchet groove 24 can be designed in the same way as before, and sound generation and main drag performance can be the same as before.

[0052] In addition, as in this embodiment, by providing the sound generator 20 using the space at the rear of the spool 10, which can be made larger in diameter, it is possible to increase the number of pitches of the ratchet groove 24. This allows the sound pitch associated with the rotation of the spool 10 to be finer, enabling the sound to be generated with a sense of precision.

[0053] Although the embodiment of the present invention has been described above, appropriate design changes are possible within the scope of the present invention. For example, the spool body 11 and the sounding body 20 may be integral or separate. The sounding body 20 may be provided at another location on the inner circumferential surface of the spool body 11. Furthermore, the boundary between the first surface 62 and the second surface 63 (see imaginary line 67) is set on the Q direction side of the deepest part 66 in the above-described embodiment, but it may be a position that overlaps with the deepest part 66, or may be set on the P direction side of the deepest part 66.
