Description

[Technical field]

[0001] The present invention relates to a reciprocating mechanism for a spinning reel, and to a spinning reel having this reciprocating mechanism. [Background technology]

[0002] A reciprocating mechanism has been disclosed for a conventional spinning reel. The reciprocating mechanism has a sliding gear that rotates in conjunction with the rotation of the handle shaft, and a cam gear that meshes with the sliding gear. The cam gear has a gear body that meshes with the sliding gear, and a boss portion that protrudes from the gear body. The boss portion engages with an engagement groove of a slider. The slider moves the spool shaft in the front-rear direction as the boss portion moves along the engagement groove.

[0003] In conventional reciprocating mechanisms, a clearance is provided between the outer circumferential surface of the boss and the wall surface of the engagement groove in order to move the boss of the cam gear along the engagement groove of the slider. This clearance can cause the outer circumferential surface of the boss to collide with the wall surface of the engagement groove when the boss moves along the engagement groove, which can cause a collision noise. To prevent this, the spinning reel of Patent Document 1 has an annular elastic body interposed between the boss and the engagement groove. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2004-065119 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the reciprocating mechanism of Patent Document 1, the annular elastic body receives a load and deforms while sliding in contact with the engaging groove during movement, which causes problems with the durability of the annular elastic body. In particular, when the annular elastic body is held in an annular retaining groove provided in the boss portion, the annular elastic body slides in contact with the engaging groove while the degree of deformation of the annular elastic body is suppressed by the annular retaining groove, so the surface of the annular elastic body is easily damaged.

[0006] The present invention has been made in consideration of the above problems, and an object of the present invention is to improve the durability of the annular elastic body in a spinning reel reciprocating mechanism and spinning reel that can suppress collisions that occur between the boss portion of the second gear and the engagement groove of the slider. [Means for solving the problem]

[0007] A spinning reel reciprocating mechanism according to one aspect of the present invention includes a first gear, a second gear, a slider, and an annular elastic body. The first gear rotates in conjunction with rotation of the handle shaft. The second gear has a gear body that meshes with the first gear and a boss portion that protrudes from the gear body. The slider has an engagement groove with which the boss portion engages. The slider moves the spool shaft in the front-rear direction as the boss portion moves along the engagement groove. The annular elastic body is attached to the boss portion so as to contact the open end of the engagement groove.

[0008] In the reciprocating mechanism of the present invention, the boss portion moves along the engagement groove of the slider with the annular elastic body attached to the boss portion of the second gear in contact with the open end of the engagement groove of the slider. With this configuration, it is possible to suppress collisions between the boss portion of the second gear and the engagement groove of the slider, and the boss portion bears the load, thereby improving the durability of the annular elastic body.

[0009] In the spinning reel reciprocating mechanism according to another aspect of the present invention, the annular elastic body is preferably disposed between the open end of the engagement groove and the gear body.

[0010] In this case, the annular elastic body contacts the outer peripheral surface of the boss portion, the gear body, and the open end of the engagement groove. In this state, when the boss portion moves along the engagement groove, the annular elastic body is compressed by the open end of the engagement groove while being supported by the outer peripheral surface of the boss portion and the gear body. This allows the annular elastic body to be stably compressed.

[0011] In a spinning reel reciprocating mechanism according to another aspect of the present invention, it is preferable that the maximum distance in the front-to-rear direction at the open end of the engagement groove is greater than the distance between the front-to-rear wall surfaces at the portion where the tip of the boss portion of the engagement groove is located. In this case, since the maximum distance of the open end of the engagement groove is greater than the distance between the wall surfaces of the engagement groove, the annular elastic body can be suitably brought into contact with the open end of the engagement groove.

[0012] In a spinning reel reciprocating mechanism according to another aspect of the present invention, it is preferable that the engagement groove has an engagement recess in which the tip of the boss is disposed, and a wide portion that is wider than the engagement recess and with which the annular elastic body comes into contact. In this case, since the engagement groove has the wide portion, the annular elastic body can be suitably brought into contact with the open end of the engagement groove.

[0013] In the spinning reel reciprocating mechanism according to another aspect of the present invention, the boss is preferably formed in a cylindrical or truncated cone shape, which allows the boss to move smoothly inside the engagement groove.

[0014] A spinning reel according to one aspect of the present invention includes a reel body, a handle shaft rotatably supported by the reel body, a spool shaft supported for movement in a front-to-rear direction relative to the reel body, and the reciprocating mechanism described above. The reciprocating mechanism moves the spool shaft in the front-to-rear direction in response to rotation of the handle shaft. The spinning reel of the present invention can achieve the same effects as the reciprocating mechanism described above. Effect of the Invention

[0015] In the present invention, in a spinning reel reciprocating mechanism and a spinning reel, it is possible to suppress collisions between the boss portion of the second gear and the engagement groove of the slider, while improving the durability of the annular elastic body interposed between the two.

[Diagram 2] FIG. 2 is a side view of the spinning reel with the side cover and the driver removed. [Diagram 3] FIG. [Figure 4A] FIG. [Figure 4B] FIG. [Diagram 5] FIG. [Figure 6] FIG. 13 is a partially enlarged cross-sectional view of an oscillating mechanism according to another embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] As shown in FIG. 1, a spinning reel 1 embodying one embodiment of the present invention comprises a reel body 3, a handle 5, a rotor 7, a spool 11, a driver 13 (see FIG. 2), and an oscillating mechanism 30 (see FIG. 2).

[0018] As shown in Fig. 1, the handle 5 is rotatably supported by the reel body 3. In this embodiment, an example is shown in which the handle 5 is disposed on the left side of the reel body 3, but the handle 5 may be disposed on the right side of the reel body 3. As shown in Fig. 2, an oscillating mechanism 30 for moving the spool 11 in the front-rear direction is disposed in the internal space of the reel body 3.

[0019] The rotor 7 is used to wind the fishing line onto the spool 11. As shown in Figures 1 and 2, the rotor 7 is disposed at the front of the reel body 3. The rotor 7 is configured to be rotatable relative to the reel body 3. For example, as shown in Figure 2, the rotor 7 is connected to a pinion gear 17 so as to be rotatable together with the reel body 3. The pinion gear 17 is rotatably supported by the reel body 3. The rotor 7 rotates in conjunction with the rotation of the pinion gear 17.

[0020] Fishing line is wound around the spool 11. The spool 11 is configured to be movable integrally with the spool shaft 9. For example, the spool 11 is attached to the tip of the spool shaft 9. As shown in FIG. 2, the spool shaft 9 is configured to be movable toward and away from the reel body 3. For example, the spool shaft 9 is supported so as to be movable in the front-rear direction relative to the reel body 3. More specifically, the spool shaft 9 is inserted into the inner periphery of a cylindrical pinion gear 17. The spool shaft 9 reciprocates in the front-rear direction relative to the reel body 3 by operation of the oscillating mechanism 30. The front-rear direction is the direction in which the spool axis X1 of the spool shaft 9 extends.

[0021] 2, the driver 13 has a drive shaft 21, a drive gear 23, and a sliding gear 31 (an example of a first gear). The drive shaft 21 rotates in conjunction with the rotation of the handle 5. For example, the handle shaft 6 of the handle 5 is attached to the drive shaft 21.

[0022] The drive shaft 21 has a drive axis X2. For example, the drive shaft 21 is formed in a cylindrical shape. The handle shaft 6 is detachably attached to the inner periphery of the drive shaft 21. The handle shaft 6 is rotatably supported by the reel body 3.

[0023] The drive gear 23 is used to rotate the rotor 7. The drive gear 23 is provided on the drive shaft 21. The drive gear 23 meshes with the pinion gear 17. The sliding gear 31 is used to move the spool shaft 9. The sliding gear 31 is provided on the drive shaft 21 with a gap between it and the drive gear 23. The spool shaft 9 and a guide shaft 34 (described later) are disposed between the drive gear 23 and the sliding gear 31. The sliding gear 31 meshes with a cam gear 33 (an example of a second gear) described later.

[0024] The drive gear 23 and the sliding gear 31 rotate in conjunction with the rotation of the handle 5 (handle shaft 6). When the drive gear 23 and the sliding gear 31 rotate, the pinion gear 17 and the cam gear 33 rotate.

[0025] The oscillating mechanism 30 moves the spool shaft 9 in the front-rear direction in conjunction with the rotation of the handle shaft 6. As shown in Fig. 3, the oscillating mechanism 30 has a sliding gear 31, a cam gear 33, a guide shaft 34, a slider 35, and an O-ring 40 (an example of an annular elastic body). Note that in Fig. 3, the teeth of the sliding gear 31 and the teeth of the cam gear 33 are shown in a simplified manner.

[0026] As described above, the sliding gear 31 constitutes the driver 13. The cam gear 33 is used to move the slider 35 in the front-rear direction. The cam gear 33 has a gear body 33a and a boss portion 33b. The gear body 33a is supported by the reel body 3 so as to be rotatable around an axis X3 parallel to the drive axis X2. The gear body 33a meshes with the sliding gear 31.

[0027] The boss portion 33b protrudes from the gear body 33a. For example, the boss portion 33b protrudes from the gear body 33a in the direction in which the drive axis X2 extends. The boss portion 33b engages with an engagement groove 37 of the slider 35, which will be described later.

[0028] The boss portion 33b, while disposed inside the engagement groove 37, moves along the engagement groove 37 in conjunction with the rotation of the gear body 33a. The boss portion 33b is formed in a cylindrical shape. In this embodiment, an example in which the boss portion 33b is formed in a cylindrical shape is shown, but the boss portion 33b may be formed in a truncated cone shape.

[0029] The guide shaft 34 is used to guide the slider 35 in the front-rear direction. The guide shaft 34 is disposed above the spool shaft 9. The guide shaft 34 is disposed parallel to the spool shaft 9 (spool axis X1) and is fixed to the reel body 3.

[0030] The slider 35 is used to move the spool shaft in the front-rear direction. The slider 35 has a slider body 36 and an engagement groove 37. The slider body 36 is fixed to the rear end of the spool shaft 9. The guide shaft 34 is inserted into the slider body 36. The slider body 36 moves in the front-rear direction along the guide shaft 34.

[0031] The engagement groove 37 is provided in the slider body 36. The boss portion 33b is arranged in the engagement groove 37. For example, in a state in which the slider body 36 is attached to the spool shaft 9 and the guide shaft 34, the engagement groove 37 extends upward from the spool shaft 9. When the engagement groove 37 is viewed from the handle 5 side in the drive shaft direction relative to the drive shaft center X2 (as in FIG. 3), the engagement groove 37 is formed in a curved shape.

[0032] 4A, the engagement groove 37 has an engagement recess 38 and a wide portion 39 (an example of an open end of the engagement groove). The tip and middle portions of the boss portion 33b are disposed in the engagement recess 38. When the engagement groove 37 is viewed from the outside in the drive shaft direction, the engagement recess 38 is formed in an inverted S-shape.

[0033] The engagement recess 38 is formed by a bottom surface 38a and a wall surface 38b surrounding the bottom surface 38a. The engagement recess 38 has a first end portion 38c1, a second end portion 38c2, and an intermediate portion 38c3 provided between the first end portion 38c1 and the second end portion 38c2. At the first end portion 38c1 and the second end portion 38c2, the wall surface 38b surrounds the bottom surface 38a. At the intermediate portion 38c3, the pair of wall surfaces 38b are disposed opposite each other.

[0034] The wide portion 39 forms the open end of the engagement groove 37. The base end of the boss portion 33b is disposed in the wide portion 39. The O-ring 40 comes into contact with the wide portion 39. The wide portion 39 is formed to be wider than the engagement recess 38. In this embodiment, the wide portion 39 is an inclined surface extending outward from the boundary 38d with the engagement recess 38 (see FIG. 5). The wide portion 39 is also an inclined surface surrounding the boundary 38d with the engagement recess 38 (see FIG. 4A).

[0035] For example, as shown in FIG. 4B, the maximum front-to-rear spacing D1 in the wide portion 39 (an example of the "maximum front-to-rear distance at the opening end of the engagement groove") is greater than the front-to-rear wall spacing D2 in the engagement recess 38 (an example of the "distance between the front-to-rear wall surfaces at the portion where the tip of the boss portion of the engagement groove is located").

[0036] Here, the maximum distance D1 and the wall distance D2 are defined on a plane perpendicular to the bottom surface 38a and parallel to the spool axis X1. This plane preferably passes through the intermediate portion 38c3 of the engagement groove 37.

[0037] The maximum distance D1 is measured using a portion on the wide portion 39 (inclined surface) that is closest to the gear body 33a of the cam gear 33. The wall surface distance D2 is measured using a pair of wall surfaces 38b that face each other in the engagement recess 38. The wall surface distance D2 may be interpreted as the maximum wall surface distance in the engagement recess 38.

[0038] The O-ring 40 is used to suppress collision between the boss portion 33b and the engagement groove 37. As shown in Fig. 5, the O-ring 40 is attached to the boss portion 33b. For example, the O-ring 40 is attached to the base end portion of the boss portion 33b. In this state, the O-ring 40 contacts the wide portion 39 of the engagement groove 37.

[0039] 5 is a cross-sectional view of the sliding gear 31, the cam gear 33, and the slider 35 cut by a plane passing through the drive axis X2 of the drive shaft 21 and the axis X3 of the cam gear 33. In the cross-sectional view of FIG. 5, each component is shown diagrammatically for ease of explanation.

[0040] 5, the O-ring 40 is attached to the outer circumferential surface of the boss portion 33b at the base end of the boss portion 33b. In this state, the O-ring 40 contacts the gear body 33a and the wide portion 39 (inclined surface) of the engagement groove 37. As a result, the O-ring 40 contacts the wide portion 39 (inclined surface) of the engagement groove 37 while contacting the gear body 33a and the boss portion 33b. In this manner, the O-ring 40 is disposed between the gear body 33a and the boss portion 33b and the wide portion 39 (inclined surface) of the engagement groove 37.

[0041] In the oscillating mechanism 30, when the sliding gear 31 rotates in conjunction with the rotation of the handle shaft 6, the cam gear 33 rotates. The rotation of the cam gear 33 causes the boss portion 33b of the cam gear 33 to move along the engagement recess 38 of the slider 35. At this time, the O-ring 40 slides on the wide portion 39 of the slider 35 while in contact with the wide portion 39 of the slider 35. By operating the oscillating mechanism 30 in this manner, the slider 35 moves the spool shaft 9 in the front-rear direction while being guided by the guide shaft 34.

[0042] The above-mentioned spinning reel 1 has the following features.

[0043] In the oscillating mechanism 30 of the spinning reel 1, the boss portion 33b moves along the engagement groove 37 (engagement recess 38) with the O-ring 40 attached to the boss portion 33b of the cam gear 33 in contact with the wide portion 39 of the engagement groove 37 of the slider 35. With this configuration, collisions occurring between the boss portion 33b of the cam gear 33 and the engagement groove 37 of the slider 35 can be suppressed.

[0044] Furthermore, in the oscillating mechanism 30 of the spinning reel 1, the O-ring 40 contacts the outer circumferential surface of the boss portion 33b, the gear body 33a, and the wide portion 39 of the engagement groove 37. In this state, when the boss portion 33b moves along the engagement groove 37 (engagement recess 38), the O-ring 40 is compressed by the wide portion 39 of the engagement groove 37 while being supported by the outer circumferential surface of the boss portion 33b and the gear body 33a. This allows the O-ring 40 to be compressed stably.

[0045] In addition, in the oscillating mechanism 30 of the spinning reel 1, the maximum front-to-rear spacing D1 of the wide portion 39 is greater than the front-to-rear wall spacing D2 of the engagement recess 38, so that the O-ring 40 can be brought into contact with the wide portion 39 of the engagement groove 37 in an optimal manner.

[0046] Furthermore, in the oscillating mechanism 30 of the spinning reel 1, the engagement groove 37 has the wide portion 39, so that the O-ring 40 can be brought into suitable contact with the wide portion 39 of the engagement groove 37.

[0047] Furthermore, in the oscillating mechanism 30 of the spinning reel 1, the boss portion 33b is formed in a cylindrical or truncated cone shape, so that the boss portion 33b can move smoothly within the engagement groove 37.

[0048] (Other embodiments) (a) In the above embodiment, an example was shown in which the wide portion 39 of the engagement groove 37 was an inclined surface. Alternatively, as shown in Fig. 6, the wide portion 139 of the engagement groove 37 may be a step portion. In Fig. 6, the same reference numerals are used for configurations that are the same as those in the above embodiment. The configurations with the same reference numerals are as described in the above embodiment.

[0049] 6, the wide portion 139 (step portion) surrounds the boundary 38d with the engagement recess 38. The wide portion 139 (step portion) comes into contact with the O-ring 40. Even with this configuration, the same effects as in the above embodiment can be obtained. [Industrial Applicability]
