Description

  The present invention relates to a spinning reel for fishing, and more particularly to a spinning reel for fishing provided with an oscillating mechanism for converting a rotational operation motion of a handle shaft mounted on a reel body into a reciprocating motion of a spool.

  Generally, an oscillating mechanism for converting the rotational movement of the handle into the longitudinal movement of the spool is provided in the reel body of the spinning reel for fishing. While this oscillating mechanism reciprocally moves the spool shaft provided with a spool at the tip in the front-rear direction through a sliding body that moves back and forth by the rotational operation of the handle, it moves through the fishing line guide portion of the rotor that rotates in conjunction with the handle. The fishing line is wound on the spool.

  As such an oscillating mechanism, one using a traverse cam shaft (see, for example, Patent Document 1) and one using a reduction gear (see, for example, Patent Document 2) are known. In any of the oscillating mechanisms, a sliding body that transmits power from the handle to the spool shaft is integrally connected to the spool shaft, and is linearly guided along the front-rear direction by the guide shaft.

Thus, the guide shaft for guiding the sliding body is inserted into the reel body so as to be parallel to the traverse cam shaft, and is prevented from falling off by a retainer screwed to the reel body. In the case of using a reduction gear, an E-type retaining ring is attached to an annular groove formed on the outer peripheral surface of the guide shaft, and the retaining shaft is locked to the partition wall of the reel body to prevent the guide shaft from coming off. Yes.

  By the way, in such a spinning reel for fishing, when the guide shaft is maintained or when the guide shaft is replaced, the retainer or the stop is removed after removing a member such as a cover fixed to the reel body by screwing. It is necessary to remove the wheel and take out the guide shaft from the reel body. For this reason, there is a possibility that the retainer or the retaining ring may be lost or damaged, and the number of parts is large, and an extremely troublesome work is required for installation and removal.

  The present invention has been made based on such circumstances, and it is an object of the present invention to provide a fishing spinning reel with good workability capable of easily attaching and detaching a guide shaft.

  The present invention that achieves the above object includes an oscillating mechanism that converts a rotational operation motion of a handle shaft mounted on a reel body into a back-and-forth reciprocating motion of a spool shaft, and the oscillating mechanism is a support formed on the reel body. The guide shaft is supported by one end portion and guides the back-and-forth movement of the sliding body integrally connected to the spool shaft. The guide shaft is connected to the reel body by a mounting screw of a cover member attached to the reel body. It is characterized by being fixed to.

  According to the spinning reel for fishing of the present invention, the guide shaft is fixed to the reel main body with the mounting screw of the cover member, so there is no need to provide a dedicated member for fixing the guide shaft to the reel main body. By reducing the number of parts and the assembly process, the manufacturing cost is reduced, the fishing spinning reel is reduced in weight, and the guide shaft can be easily attached and removed.

  1 and 2 show a fishing spinning reel 10 according to a preferred embodiment of the present invention. This fishing spinning reel 10 has a reel body 12 to which a lid (not shown) is detachably fixed with a plurality of set screws (not shown), for example, on one side of a rigid body portion 12a. It can be attached to a fishing rod via a rod attachment portion 12c formed at the end of the leg portion 12b extending from the rod. In the internal space of the reel body 12, a winding drive mechanism 18 for rotating the rotor 14 to wind the fishing line around the spool 16 and an oscillating mechanism 20 for reciprocating the spool 16 back and forth are provided. It has been.

  The winding drive mechanism 18 of the present embodiment includes a drive gear 26 that is rotatably supported in the reel body 12 and is fixed to a handle shaft 24 that is rotated by a handle 22, and a pinion gear 28 that meshes with the drive gear 26. Is provided. The pinion gear 28 extends in the front-rear direction orthogonal to the handle shaft 24 and is supported on the reel body 12 through two front and rear bearings 30 and 32 so as to be freely rotatable on the rear end side of the cylindrical shaft 28a. Is provided. The rotor 14 provided with the bail 34 and the fishing line guide part (not shown) is integrally attached to the tip of the cylindrical shaft 28a.

  A spool shaft 36 passes through the pinion gear 28 and the cylindrical shaft 28 a and extends in a direction perpendicular to the handle shaft 24. The spool shaft 36 is arranged concentrically with the cylindrical shaft 28 a and can move back and forth along the direction perpendicular to the handle shaft 24 with respect to the cylindrical shaft 28 a and the reel body 12. A spool 16 around which a fishing line is wound is attached to the tip of the spool shaft 36.

  The oscillating mechanism 20 that reciprocates the spool 16 in the front-rear direction is formed as a so-called reduction gear type in this embodiment. The oscillating mechanism 20 has a large gear 40 that meshes with and interlocks with a small gear 38 that rotates integrally with the handle shaft 24, and protrudes from the large gear 40 and is eccentric from the rotation center axis of the large gear 40. When the large gear 40 rotates when the engaging protrusion 42 is engaged with the cam groove 48 of the sliding body 46 integrally connected to the rear end portion of the spool shaft 36 with the screw 44 in this embodiment, The sliding body 46 can be driven in the front-rear direction along the guide shaft 50. In the oscillating mechanism 20, when the drive shaft 18 is rotated by the rotation operation of the handle 22, the large gear 40 that meshes with the gear 38 on the drive shaft 18 is decelerated and rotated. The engaging protrusion 42 rotates, and the sliding body 46 reciprocates back and forth by the guide of the cam groove 48 engaged with the engaging protrusion 42. Therefore, the spool shaft 36 attached to the sliding body 46 reciprocates (backs and forth) along the axial direction in the cylindrical shaft 28a. The spool stroke, which is the longitudinal movement distance of the spool shaft 36, is determined by the amount of eccentricity of the engagement protrusion 42 from the rotation center axis of the interlocking gear and the longitudinal distance of the cam groove 48.

  In the fishing spinning reel 10 thus formed, when the handle 22 is rotated to rotate the handle shaft 24, the spool 16 is moved via the spool shaft 36 attached to the sliding body 46 of the oscillating mechanism 20. While reciprocating back and forth, the rotor 14 is rotationally driven via the drive gear 26, pinion gear 28 and cylindrical shaft 28a of the winding drive mechanism. Accordingly, the fishing line is wound on the spool 16 almost uniformly while being guided by the fishing line guide portion 32.

  In the present embodiment, a reverse rotation prevention mechanism including a well-known one-way clutch 52 that prevents reverse rotation of the rotor 14 (rotation in the direction of feeding the fishing line from the spool) is disposed in the reel body 12. This reverse rotation prevention mechanism can be switched through a switching lever 54 provided on the rear end wall portion of the reel body 12, and the rotor 14 can be switched between a state in which the rotor 14 can be rotated forward and backward and a state in which the rotor 14 can rotate forward and cannot be rotated in reverse. . Regardless of the state of the rotor 14, when the handle 22 is rotated in the forward rotation direction (rotation in the direction of winding the fishing line on the spool), the bail 34 at the fishing line discharge position is moved through a known return mechanism (not shown). 1 can be returned to the fishing line winding position shown in FIG.

  As shown in an enlarged view in FIG. 2, the guide shaft 50 that guides the sliding body 46 through a leg portion 46 a that extends downward, that is, in a direction away from the spool shaft 36, is placed in the body portion 12 a of the reel body 12. It is arranged in parallel with the spool shaft 36. The guide shaft 50 is formed in an elongated rod shape having a circular or non-circular cross-sectional shape, and is supported by a bottomed structure fixing hole 56 (support portion) formed in the reel body at one end side. The rear end side is supported by a support hole 58 that is coaxial with the fixing hole 56 and is formed so as to penetrate the boss or protrusion 12d of the body portion 12a.

  The support hole 58 is formed to be relatively long along the axial direction in parallel with the spool shaft 36, and when the guide shaft 50 is received from the opening end opened to the outside on the rear end side, the guide shaft 50 is It is possible to guide forward while maintaining a parallel state with the spool shaft 36. That is, the support hole 58 is formed to have an axial length that can move the guide shaft 50 in parallel with the spool shaft 36 while suppressing the deflection of the tip of the guide shaft 50 inserted from the opening end. The cross-sectional shape is formed in a shape and a size that form a slight gap between the guide shaft 50 and a slidable portion. The cross-sectional shape of the fixing hole 56 that supports the distal end side of the guide shaft 50 is preferably formed similarly to the cross-sectional shape of the support hole 58.

  The guide shaft 50 inserted through the fixed hole 56 and the support hole 58 formed as described above is prevented from moving forward at the bottom side of the fixed hole 56 at the front end side, and the cover member attached to the reel body 12 at the rear end side. The rear portion 62 a of the mounting screw 62 of the 60 is prevented from moving backward and is fixed to the reel body 12. The length of the guide shaft 50 exposed between the fixed hole 56 and the support hole 58 in the internal space of the reel body 12, that is, the length in the axial direction for forming the guide portion, is substantially equal to the spool stroke described above. However, it may be longer than the spool stroke as long as interference with the leg 46a of the sliding body 46 is prevented. The guide shaft 50 may be inserted into a through hole or groove formed in the leg 46a as long as it can guide the sliding body 46 via the leg 46a. It may be in sliding contact with the side of 46a. In the case of sliding contact with the side of the leg 46a, for example, it is guided with the leg 46a sandwiched between appropriate portions such as the wall of the reel body 12, or the two guide shafts 50 Guidance can be provided with the leg 46a interposed therebetween.

  In the present embodiment, the screw hole 64 for screwing the mounting screw 62 of the cover member 60 that covers the bottom from the rear part of the reel body 12 to form a smooth outer shape and that protects from an external impact is provided in the support hole 58. It is formed in a direction intersecting or orthogonal to the central axis. The screw hole 64 is formed in the boss portion 12d at a position where the rear end of the guide shaft 50 is disposed when the front end of the guide shaft 50 is brought into contact with the bottom wall of the fixing hole 56, and opens downward. When the mounting screw 62 of the cover member 60 is tightened in the screw hole 64, the mounting screw 62 closes the opening end of the support hole 58 and locks the rear end of the guide shaft 50, so that the guide shaft 50 is removed from the support hole 58. It is prevented from coming out. The cover member 60 is pressed against the boss portion 12d and firmly attached. The opening end of the support hole 58 is covered with the cover member 60, so that intrusion of foreign matter and deformation due to external force are prevented.

  As described above, the support hole 58 for supporting the guide shaft 50 and the screw hole 64 for screwing the mounting screw 62 of the cover member 60 are formed in the boss portion 12 d of the reel body 12, so that the guide shaft 50 is connected to the cover member 60. It is possible to fix the guide shaft 50 to the reel body 12 with 60 mounting screws 62, and it is not necessary to provide a dedicated member for fixing the guide shaft 50 to the reel body 12, and the manufacturing cost is reduced due to the reduction in the number of parts and the assembly process. In addition to being reduced, the fishing spinning reel 10 is reduced in weight, and the guide shaft 50 can be easily attached and removed.

  3 and 4 show an embodiment in which a traverse cam shaft 66 is used for the oscillating mechanism 20. Since various embodiments or modifications described below are basically the same as those in the above-described embodiment, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted.

  The oscillating mechanism 20 of the present embodiment has a traverse cam shaft 66 disposed in parallel to the spool shaft 36. The traverse cam shaft 66 has a helical cam groove 66a with which a projection 68a fixed to a sliding body 68 is engaged, and is rotated by a pinion gear 28 via a small gear 67 on the distal end side. Accordingly, when the handle 22 is rotated, the traverse cam shaft 66 is rotated, and the spool shaft 36 is reciprocated in the front-rear direction by the sliding body 68 guided by the cam groove 66a. A cover member 70 is attached to the outside of the rear portion of the traverse cam shaft 66.

  As shown in an enlarged view in FIG. 4, in this embodiment, a screw hole 64 for screwing the attachment screw 62 of the cover member 70 is formed coaxially with the support hole 58, and this open end is the attachment screw. Sealed at 62. The rear end portion of the guide shaft 50 whose one end portion is supported by the support portion of the reel body in the same manner as in the above-described embodiment is locked by the front end of the mounting screw 62 and pulled out from the support hole 58. It is prevented.

  In this embodiment, the screw hole 64 into which the mounting screw 62 of the cover member 70 is screwed is formed coaxially with the support hole 58, so that the support hole 58 and the screw hole 64 can be easily formed.

  FIG. 5 is substantially the same as the embodiment shown in FIGS. 1 and 2, but shows an embodiment in which the support hole 58 of the guide shaft 50 is opened to the spool side, that is, the front side of the reel body 12. Also in this embodiment, as in the embodiment shown in FIGS. 3 and 4, the mounting screw 62 of the cover member 60 is screwed into the screw hole 64 formed coaxially with the support hole 58 from the front. In this case, since the front part of the cover member 60 is bent inside the trunk part of the rotor 14 and disposed inside the rotor 14 of the mounting screw 64, the entire cover member 60 forms a smooth outer surface.

FIG. 6 shows an embodiment in which a screw hole 64 is formed in a direction intersecting the support hole 58.
In this embodiment, an upper cover member 72 and a lower cover member 74 are provided at the rear part of the fishing spinning reel 10, and the upper cover member 72 is fixed to the leg portion 12 b by an attaching screw 74, and the lower cover member 76. Is fixed to the reel main body 12 by mounting screws 62. A screw hole 64 into which the mounting screw 62 is screwed is formed along a direction intersecting the support hole 58 in a non-orthogonal state. In this way, by forming the screw hole 64 so as to intersect with the support hole 58 in an orthogonal or non-coaxial manner, the outer shape of the cap or cover member 74 can be formed in an appropriate shape, and the design The degree of freedom can be improved.

  Further, cover members 72 and 76 having different forms and different numbers of parts can be selectively attached to and detached from a plurality of attachment portions (screwed portions of attachment screws 62 and 74) formed from the bottom portion to the leg portion of one reel body. Thus, a reel body having a different appearance can be efficiently realized. It should be noted that the number of cover members is not limited to two, and a mounting portion may be provided on the reel body so that three cover members can be attached, and the number of cover members attached is not limited.

  FIG. 7 is the same as the embodiment shown in FIG. 6 except that the rear portion is covered with one large cover member 78 instead of the two cover members 72 and 76 shown in FIG. By forming the gap 80 in the intermediate portion, even if an impact acts on the cover member 78, the gap 80 can prevent the impact from acting on the reel body 12.

  Although various embodiments and modifications of the present invention have been individually described above, the present invention is not limited to any of the embodiments or modifications, and is appropriately combined or modified according to various applications. Is possible.
