Description

Technical Field

[0001] The present invention relates to a reciprocating movement mechanism for a spinning reel and a spinning reel having the reciprocating movement mechanism. Background Technology

[0002] A reciprocating mechanism has been disclosed in conventional spinning reels. This reciprocating mechanism includes a sliding gear that rotates in conjunction with the rotation of a 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 protruding from the gear body. The boss engages with a locking groove in a slider. By moving the boss along the locking groove, the slider moves the spool shaft in the back-and-forth direction.

[0003] In conventional reciprocating mechanisms, a clearance is provided between the outer peripheral surface of the boss and the wall of the engagement groove in order for the boss of the cam gear to move along the engagement groove of the slider. Because of this clearance, when the boss moves along the engagement groove, the outer peripheral surface of the boss may collide with the wall of the engagement groove, causing a collision noise. To suppress this situation, in the spinning type winding wheel of Patent Document 1, an annular elastomer is sandwiched between the boss and the engagement groove.

[0004] Patent document 1: Japanese Patent Application Publication No. 2004-065119.

[0005] In the reciprocating mechanism of Patent Document 1, the annular elastomer is subjected to load and deforms while sliding contact during movement, which makes it difficult to maintain the durability of the annular elastomer. In particular, when the annular elastomer is held in the annular retaining groove provided on the boss, the annular elastomer slides in contact with the engaging groove while the annular retaining groove suppresses the degree of deformation of the annular elastomer, so the surface of the annular elastomer is easily damaged. Summary of the Invention

[0006] The present invention was made in view of the above-mentioned problems. The object of the present invention is to improve the durability of the annular elastomer in the reciprocating movement mechanism and the spinning winding wheel of the spinning winding wheel, which can suppress the collision between the boss portion of the second gear and the engagement groove of the slider.

[0007] A reciprocating mechanism for a spinning reel according to one aspect of the present invention comprises a first gear, a second gear, a slider, and an annular elastic body. The first gear rotates in conjunction with the rotation of a handle shaft. The second gear has a gear body that meshes with the first gear and a boss protruding from the gear body. The slider has an engagement groove that engages with the boss. The slider moves along the engagement groove via the boss, causing the reel shaft to move in the back-and-forth direction. The annular elastic body is fitted onto the boss in such a way that it contacts the open end of the engagement groove.

[0008] In the reciprocating mechanism of the present invention, the annular elastomer fitted onto the boss portion of the second gear is in contact with the opening end of the engagement groove of the slider, and the boss portion moves along the engagement groove. With this structure, collisions occurring between the boss portion of the second gear and the engagement groove of the slider can be suppressed, and since the boss portion bears the load, the durability of the annular elastomer can be improved.

[0009] In another aspect of the present invention, in the reciprocating movement mechanism of a spinning winding wheel, it is preferred that an annular elastomer is disposed between the opening end of the engagement groove and the gear body.

[0010] In this configuration, the annular elastomer contacts the outer peripheral surface of the boss, the gear body, and the opening end of the engagement groove. In this state, as the boss moves along the engagement groove, the annular elastomer, supported by the outer peripheral surface of the boss and the gear body, is compressed by the opening end of the engagement groove. This allows for stable compression of the annular elastomer.

[0011] In another aspect of the present invention, the reciprocating mechanism of a spinning winding wheel preferably has a maximum front-to-back distance at the opening end of the engagement groove that is greater than the distance between the front-to-back walls at the end portion of the engagement groove's boss portion. In this case, since the maximum distance at the opening end of the engagement groove is greater than the distance between the walls of the engagement groove, the annular elastomer can be properly contacted with the opening end of the engagement groove.

[0012] In another aspect of the present invention, the reciprocating mechanism of a spinning winding wheel preferably includes an engaging recess at the end of a boss portion and a wide portion formed to be wider than the engaging recess, which contacts the annular elastomer. In this case, because the engaging groove has a wide portion, the annular elastomer can be properly contacted with the opening end of the engaging groove.

[0013] In another aspect of the present invention, the reciprocating mechanism of a spinning winding wheel preferably has a boss formed in the shape of a cylinder or a frustum conical. This allows the boss to move smoothly within the engaging groove.

[0014] A spinning reel according to one embodiment of the present invention comprises: a reel body; a handle shaft rotatably supported by the reel body; a spool shaft movably supported relative to the reel body in a front-rear direction; and the aforementioned reciprocating mechanism. The reciprocating mechanism is linked to the rotation of the handle shaft, causing the spool shaft to move in the front-rear direction. The spinning reel of the present invention achieves the same effects as the aforementioned reciprocating mechanism.

[0015] Invention Effects

[0016] In this invention, in the reciprocating movement mechanism of the spinning winding wheel and the spinning winding wheel, the durability of the annular elastomer sandwiched between the boss of the second gear and the engagement groove of the slider can be improved while suppressing the collision that occurs between them.

[0024] The spinning type winding wheel 1 adopts one embodiment of the present invention, as shown in the figure. Figure 1 As shown, it includes a winding reel body 3, a handle 5, a rotor 7, a drum 11, and a drive unit 13 (see reference). Figure 2 ) and swing mechanism 30 (refer to Figure 2 ).

[0025] like Figure 1 As shown, the handle 5 is rotatably supported by the winding reel body 3. In this embodiment, an example is shown where the handle 5 is positioned on the left side of the winding reel body 3, but the handle 5 can also be positioned on the right side of the winding reel body 3. Figure 2 As shown, an oscillating mechanism 30 for moving the drum 11 in the front-back direction is arranged in the internal space of the winding wheel body 3.

[0026] Rotor 7 is used to wind fishing line into spool 11. For example... Figure 1 and Figure 2 As shown, the rotor 7 is positioned at the front of the winding reel body 3. The rotor 7 is configured to rotatably rotate relative to the winding reel body 3. For example, as... Figure 2As shown, the rotor 7 and the pinion 17 are rotatably connected as a single unit. The pinion 17 is rotatably supported by the winding wheel body 3. The rotor 7 and the pinion 17 rotate in tandem.

[0027] The fishing line is wound onto the spool 11. The spool 11 is configured to move integrally with the spool shaft 9. For example, the spool 11 is mounted at the end of the spool shaft 9. Figure 2 As shown, the spool 9 is configured to move forward and backward relative to the winding reel body 3. For example, the spool 9 is supported so as to be movable in the front-back direction relative to the winding reel body 3. Specifically, the spool 9 is inserted into the inner circumference of the cylindrical pinion 17. The spool 9 reciprocates in the front-back direction relative to the winding reel body 3 by means of the action of the oscillating mechanism 30. The front-back direction is the direction in which the spool axis X1 of the spool 9 extends.

[0028] like Figure 2 As shown, the drive unit 13 has a drive shaft 21, a drive gear 23, and a sliding gear 31 (an example of the 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 mounted on the drive shaft 21.

[0029] The drive shaft 21 has a drive shaft center X2. For example, the drive shaft 21 is formed in a cylindrical shape. The handle shaft 6 is detachably mounted on the inner circumference of the drive shaft 21. The handle shaft 6 is rotatably supported by the winding wheel body 3.

[0030] Drive gear 23 is used to rotate rotor 7. Drive gear 23 is located on drive shaft 21. Drive gear 23 meshes with pinion 17. Sliding gear 31 is used to move drum shaft 9. Sliding gear 31 is located on drive shaft 21 at a distance from drive gear 23. Drum shaft 9 and guide shaft 34 (described later) are arranged between drive gear 23 and sliding gear 31. Sliding gear 31 meshes with cam gear 33 (an example of the second gear) described later.

[0031] The drive gear 23 and the sliding gear 31 rotate in conjunction with the rotation of the handle 5 (handle shaft 6). If the drive gear 23 and the sliding gear 31 rotate, the pinion 17 and the cam gear 33 will rotate.

[0032] The swing mechanism 30 is linked to the rotation of the handle shaft 6, causing the drum shaft 9 to move in the back-and-forth direction. For example... Figure 3 As shown, the swing mechanism 30 includes a sliding gear 31, a cam gear 33, a guide shaft 34, a slider 35, and an O-ring 40 (an example of a ring-shaped elastomer). Additionally, in Figure 3 In the diagram, the teeth of the sliding gear 31 and the cam gear 33 are simplified and represented.

[0033] The sliding gear 31 constitutes the drive body 13 as described above. 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 rotatably supported by the winding wheel body 3 about an axis X3 parallel to the drive axis X2. The gear body 33a meshes with the sliding gear 31.

[0034] 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 extending from the drive shaft X2. The boss portion 33b engages with the engagement groove 37 of the slider 35, which will be described later.

[0035] When the boss portion 33b is disposed inside the engagement groove 37, it 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 also be formed in a frustum conical shape.

[0036] The guide shaft 34 is used to guide the slider 35 in the front-to-back direction. The guide shaft 34 is positioned above the drum shaft 9. The guide shaft 34 is arranged parallel to the drum shaft 9 (drum shaft X1) and is fixed to the winding reel body 3.

[0037] The slider 35 is used to move the spool shaft in the back-and-forth direction. The slider 35 has a slider body 36 and a locking groove 37. The slider body 36 is fixed to the rear end of the spool shaft 9. Furthermore, a guide shaft 34 is inserted through the slider body 36. The slider body 36 moves along the guide shaft 34 in the back-and-forth direction.

[0038] A locking groove 37 is provided on the slider body 36. A boss 33b is provided in the locking groove 37. For example, when the slider body 36 is assembled with the drum shaft 9 and the guide shaft 34, the locking groove 37 extends upward from the drum shaft 9. When the locking groove 37 is viewed from the handle 5 side in the drive shaft direction about the drive shaft center X2 ( Figure 3 In the case of ( ), the engagement groove 37 is formed into a curved shape.

[0039] like Figure 4A As shown, the engaging groove 37 has an engaging recess 38 and a wide portion 39 (an example of the opening end of the engaging groove). The end portion and the middle portion of the boss portion 33b are disposed in the engaging recess 38. When the engaging groove 37 is viewed from the outside in the drive shaft direction, the engaging recess 38 is formed into an inverted S-shape.

[0040] The engaging recess 38 is formed by a bottom surface 38a and a wall surface 38b surrounding the bottom surface 38a. The engaging recess 38 has a first end portion 38c1, a second end portion 38c2, and an intermediate portion 38c3 disposed 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. In the intermediate portion 38c3, a pair of wall surfaces 38b are arranged opposite to each other.

[0041] The wide portion 39 forms the opening end of the engaging groove 37. The base end of the boss portion 33b is disposed on the wide portion 39. The O-ring 40 contacts the wide portion 39. The wide portion 39 is formed to be wider than the engaging recess 38. In this embodiment, the wide portion 39 is an inclined surface extending outward from the boundary 38d of the engaging recess 38 (see reference). Figure 5 Furthermore, the wide portion 39 is an inclined surface that surrounds the boundary 38d of the engaging recess 38 (see reference). Figure 4A ).

[0042] For example, such as Figure 4B As shown, the maximum front-to-back distance D1 of the wide portion 39 (an example of "the maximum front-to-back distance of the opening end of the engaging groove") is greater than the front-to-back wall distance D2 of the engaging recess 38 (an example of "the distance between the front-to-back walls of the portion where the boss of the engaging groove exists").

[0043] Here, the maximum spacing D1 and the wall spacing D2 are defined on a plane orthogonal to the bottom surface 38a and parallel to the drum axis X1. This plane preferably passes through the middle portion 38c3 of the engagement groove 37.

[0044] The maximum gap D1 is measured using the portion of the wide section 39 (inclined surface) closest to the gear body 33a of the cam gear 33. The wall gap D2 is measured using a pair of opposing wall surfaces 38b in the engagement recess 38. The wall gap D2 can also be interpreted as the maximum wall gap of the engagement recess 38.

[0045] O-ring 40 is used to suppress collisions that occur between the boss 33b and the engagement groove 37. For example... Figure 5 As shown, the O-ring 40 is fitted onto the boss portion 33b. For example, the O-ring 40 is fitted onto the base end of the boss portion 33b. In this state, the O-ring 40 contacts the wide portion 39 of the engagement groove 37.

[0046] in addition, Figure 5 It 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 shaft center X2 of the drive shaft 21 and the shaft center X3 of the cam gear 33. Figure 5 The sectional views are schematic representations of the structures to facilitate explanation.

[0047] In detail, such as Figure 5 As shown, the O-ring 40 is fitted onto the outer peripheral surface of the boss portion 33b at its base end. In this state, the O-ring 40 contacts the gear body 33a and the widest portion 39 (inclined surface) of the engagement groove 37. Thus, the O-ring 40 contacts the widest portion 39 (inclined surface) of the engagement groove 37 while in contact with the gear body 33a and the boss portion 33b. In this way, the O-ring 40 is positioned between the gear body 33a and the boss portion 33b and the widest portion 39 (inclined surface) of the engagement groove 37.

[0048] In the swing mechanism 30, if the sliding gear 31 rotates in conjunction with the rotation of the handle shaft 6, the cam gear 33 rotates. Due to the rotation of the cam gear 33, the boss portion 33b of the cam gear 33 moves along the engaging recess 38 of the slider 35. At this time, the O-ring 40 slides against the wide portion 39 of the slider 35 while in contact with it. By actuating the swing mechanism 30 in this way, the slider 35 is guided by the guide shaft 34 while the drum shaft 9 moves in the back-and-forth direction.

[0049] The aforementioned spinning type winding wheel 1 has the following characteristics.

[0050] In the oscillating mechanism 30 of the spinning type winding wheel 1, the O-ring 40, which is fitted onto the boss portion 33b of the cam gear 33, is in contact with the wide portion 39 of the engagement groove 37 of the slider 35, and the boss portion 33b moves along the engagement groove 37 (engagement recess 38). With this structure, collisions that occur between the boss portion 33b of the cam gear 33 and the engagement groove 37 of the slider 35 can be suppressed.

[0051] Furthermore, in the oscillating mechanism 30 of the spinning reel 1, the O-ring 40 contacts the outer peripheral 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 (engaging recess 38), the O-ring 40 is compressed by the wide portion 39 of the engagement groove 37 while being supported by the outer peripheral surface of the boss portion 33b and the gear body 33a. Thus, the O-ring 40 can be stably compressed.

[0052] Furthermore, in the swing mechanism 30 of the spinning type winding wheel 1, since the maximum distance D1 in the front-to-back direction of the wide portion 39 is larger than the wall distance D2 in the front-to-back direction of the engaging recess 38, the O-ring 40 can be properly contacted with the wide portion 39 of the engaging groove 37.

[0053] Furthermore, in the oscillating mechanism 30 of the spinning type winding wheel 1, since the engaging groove 37 has a large width portion 39, the O-ring 40 can be properly contacted with the large width portion 39 of the engaging groove 37.

[0054] Furthermore, in the swing mechanism 30 of the spinning type winding wheel 1, since the boss portion 33b is formed in the shape of a cylinder or a frustum cone, the boss portion 33b can move smoothly inside the engaging groove 37.

[0055] (Other implementation methods)

[0056] (a) In the foregoing embodiment, an example is shown where the widest portion 39 of the engaging groove 37 is an inclined surface. Instead, as... Figure 6 As shown, the wide portion 139 of the engaging groove 37 can also be a stepped portion. Figure 6 In this document, the same reference numerals are used for structures identical to those in the aforementioned embodiments. For structures with the same reference numerals, the description of the aforementioned embodiments applies.

[0057] like Figure 6 As shown, the wide portion 139 (step portion) surrounds the boundary 38d of the engaging recess 38. The O-ring 40 contacts the wide portion 139 (step portion). With this configuration, the same effect as in the aforementioned embodiment can be obtained.
