Description

  The present invention relates to a fishing spinning reel, and more particularly, to a fishing spinning reel in which a reel body has a reel body in which a leg portion attached to a fishing rod is extended and a lid that covers an opening of the reel body. .

  In general, a reel body of a spinning reel includes a reel body that houses and supports a drive mechanism for driving various members by a rotational movement of a handle, and a lid that covers an opening of the reel body. Normally, the lid is fixed to the reel body using a plurality of screws so that the drive mechanism in the reel body can be maintained and maintained. By projecting the screw for fixing the lid to the reel body to the outside, the fishing line is easily caught, which may hinder the fishing operation, and a suitable appearance cannot be formed.

In order to prevent such catching of the fishing line and to improve operability and appearance, a spinning reel for fishing has been developed in which a fixing screw for fixing the cover plate is covered with a cover and is prevented from being exposed to the outside. (For example, refer to Patent Document 1).
In this spinning reel, the reel body and the lid are firmly fixed with fixing screws, and the fixing screws are covered with a cover, so that these fixing screws are not exposed to the outside, and fishing lines are caught. Can be prevented.

In addition, the connecting means is formed on both the reel body and the cover plate, and the cover plate is rotated around the axis of the handle shaft to switch the connecting means between the connected state and the separated state. Spinning reels that can fix or separate a cover plate have been developed (see, for example, Patent Document 2).
Japanese Utility Model Publication No. 2-17071 Japanese Patent Laid-Open No. 5-70272

  In the case where the fixing screw is covered with the cover, not all of the cover plate is fixed, but the cover plate on the leg side attached to the fishing rod is not fixed. When picking up, the reel body on the leg side tends to bend upward, that is, on the side of the fishing rod. As a result, a gap is created between the lid plate and the reel body when winding the heavy load, and the winding efficiency and durability of the drive mechanism are increased. This causes a problem such as a decrease in performance or a decrease in the rigidity of the reel body.

  In the case of a spinning reel that can be fixed or separated by rotating the reel body and the lid, the concentricity of the reel body and the lid plate, that is, the drive shaft of the drive mechanism in the reel body is set to the reel body and the lid plate. It is difficult to maintain a high degree of concentricity when supported by bearings provided on each of these, and it is difficult to obtain good rotational performance. Particularly, since the connecting means is separated or fixed by rotating the cover plate, there is a high possibility that the reel body and the cover plate will be loose or the outer peripheral shape may be displaced. This further reduces the rotational performance.

  The present invention has been made based on such circumstances, and the reel body and the lid can be fastened and fixed in a well balanced manner without exposing the screw to the outside, and the efficiency and rigidity during the winding operation can be achieved. An object of the present invention is to provide a fishing spinning reel capable of preventing the decrease of the above.

  A spinning reel for fishing according to the present invention that achieves the above object includes a reel body having a reel body with legs extended to a fishing rod and a lid that covers an opening of the reel body, and the reel body. A handle shaft that is supported and rotates to drive the rotor, and the lid is a fishing spinning reel that is fastened and fixed to the reel body so that the fixing screw is not exposed to the outside. A lift preventing portion is formed in the vicinity of the leg portion to engage with an engaging member attached to the reel body to prevent the lift from the reel body.

  The engaging member is preferably provided with a cover member that is mounted on the outer surface of the reel body.

  According to the spinning reel for fishing of the present invention, the lifting prevention portion provided on the lid body engages with the engaging member attached to the reel body in the vicinity of the leg portion, thereby resisting a large load. Even when the fishing line is wound up, the lid body is prevented from floating from the reel body, so that the reel body and the lid body can be fastened and fixed firmly and balanced without exposing the screw to the outside. It is possible to prevent a reduction in efficiency and rigidity during operation.

  When the engaging member is provided on the cover member mounted on the outer surface of the reel body, the cover body and the lid body can be fixed to the reel body at the same time, simplifying the work process and reducing the number of parts. Thus, the cost can be reduced.

  1 to 4 show a fishing spinning reel 10 according to a preferred embodiment of the present invention. The spinning reel 10 for fishing is a reel body in which a lid 12b (see FIG. 4) is detachably fixed to one side of a rigid reel body 12a by a plurality of fixing screws (not shown), for example, three. 12 and can be attached to a fishing rod through a rod attachment portion 12d formed at an end portion of a leg portion 12c extending from the upper portion of the reel body 12a. The reel body 12a is formed with an internal space A that is open on one side, and a winding drive mechanism for rotating the rotor 14 and winding the fishing line around the spool 16 in the internal space A. 18 and an oscillating mechanism 20 that reciprocates the spool 16 back and forth. The internal space A containing such various mechanisms is closed by the lid body 12b and blocked from the outside.

  The reel body 12a and the lid body 12b forming the reel body 12 are opposed to the engaging recess 13a provided on the lower side of the reel body 12a on the opposite side of the leg portion 12c and the back surface of the lid body 12b, that is, the reel body 12a. By engaging with the engaging convex portion 13b protruding from the side, it is accurately positioned at a required position covering the opening of the internal space A. In contrast to the illustrated embodiment, the engaging protrusion 13b may be provided on the reel body 12a, and the engaging recess 13a may be provided on the lid 12b. In addition, the engagement recess 13a and the engagement protrusion 12b, which serve as a certificate of incorporation, are not limited to a pair, and the formation positions thereof are also set as appropriate.

  The lid body 12b accurately positioned with respect to the reel body 12a is engaged with the reel body 12a by screwing a fixing screw inserted into an attachment hole formed in the lid body 12b into the screw hole 11 shown in FIG. Mounted firmly. In this embodiment, a total of three screw holes 11 are formed on the spool 16 side, two on the front side and one on the rear side of the reel body 12a located in the rotor 14, and the rear fixing screw is externally provided by a rear cap described later. It is covered so as not to be exposed.

  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. As shown in FIG. 4, the handle shaft 24 is rotatably supported by a bearing 30a mounted on the reel body and a bearing 30b supported by the lid 12b. The pinion gear 28 driven by the handle shaft 24 and the drive gear 26 extends in the front-rear direction perpendicular to the handle shaft 24 and is rotatably supported by the reel body 12 via the front and rear bearings 32a and 32b. It is provided on the outer peripheral portion on the rear end side of the cylindrical shaft 28a. 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. The engaging protrusion 42 is engaged with the cam groove 46 of the sliding body 44 integrally connected to the rear end portion of the spool shaft 36 with a screw or the like. It can be driven in the front-rear direction along the guide shaft 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.

  Further, as shown in FIG. 1, a rear cap 50 extending from the bottom of the reel main body 12 to the lower part of the leg portion 12c is provided as a cover member at the rear of the reel main body 12. Yes. The rear cap 50 is formed by smoothly forming an outer shape of the rear portion of the reel body extending from the bottom to the rear portion of the reel body 12 and a part of the leg portion 12c into a smoothly continuous outer shape, thereby preventing the fishing line and the like from being caught. Further, by forming a gap B between the reel body 12a and the reel body 12a, the reel body 12 can be protected from an external impact.

  The rear cap 50 of the present embodiment has a truncated cone-shaped protrusion 52 that abuts the rear part of the lower portion of the reel body 12 a protruding forward and upward from the lower position. A mounting hole 56 is recessed. The mounting hole 56 is such that the head of the fixing screw 54 does not protrude outward when the fixing screw 54 is screwed into the screw hole of the reel body 12a with the protrusion 52 engaged with the reel body 12a. It is formed to a depth. In addition, an engaging portion 60 that closely engages with a recess 58 formed in the rear portion of the leg portion 12c and an elongated protrusion 62 that protrudes forward are provided at an upper portion of the rear cap 50. The elongated protrusion 62 has a cylindrical outer shape, and has a length and thickness sufficient to function as an engaging member that supports the lifting prevention portion 72 of the lid 12b, as will be described later.

  In order to hold the rear cap 50 on the reel body 12a, the reel body 12a is formed with a screw hole for screwing the fixing screw 54 and a support hole 64 for accommodating the elongated protrusion 62 of the rear cap 50. The support hole 64 has a cross-sectional shape that fits closely to the protrusion 62, communicates with a mounting hole 66 that receives the fixing screw 68 from the front of the reel body 12a, and penetrates the reel body 12a in the front-rear direction. A fixing screw 68 mounted from the front in the mounting hole 66 is screwed into a screw hole 62a formed in the protrusion 62 of the rear cap 50, whereby the rear cap 50 is engaged with the reel body 12a and firmly fixed. be able to. The mounting hole 66 is also formed with a depth at which the head of the fixing screw 68 that is tightened and fixed does not protrude to the outside, thereby preventing catching of a fishing line or the like.

  As shown in an enlarged view in FIGS. 2 and 3, a rectangular groove 70 is formed in a state intersecting or orthogonal to the central axis of the support hole 64. The groove 70 is open on one side of the reel body 12a, that is, the side on which the lid body 12b is attached, and accommodates the lifting prevention portion 72 protruding from the inner surface side of the lid body 12b. The groove 70 and the anti-lifting portion 72 are formed in a rectangular shape larger than the support hole 64 when viewed in a plane perpendicular to the axis of the support hole 64. Further, a round hole or a through hole 72a having an inner diameter corresponding to the outer diameter of the protrusion 62 of the rear cap 50 is formed in the lifting prevention portion 72 of the lid body 12b. The through hole 72a is coaxial with the support hole 64 when the lifting prevention portion 72 is inserted into the groove 70 and the lid 12b is accurately positioned so as to close the opening of the internal space A formed in the reel body 12a. To match the shape.

  The lid 12b formed with such a lift preventing portion 72 is installed in the reel body 12a after accommodating members constituting various mechanisms in the internal space A, and is mounted on one side of the internal space A. Close the formed opening. At this time, the engagement protrusion 13b provided at the lower portion of the lid 12b is fitted into the corresponding engagement recess 13a of the reel body 12a, so that it can be accurately positioned with respect to the reel body 12a. Then, the lifting prevention portion 72 protruding from the inner surface side of the lid 12b is inserted into the groove 70 provided in the upper portion of the reel body 12a, and the through hole 72a is aligned with the support hole 64. A fixing screw (not shown) is inserted into the mounting hole of the lid 12b and screwed into the screw hole 11 of the reel body 12a. Then, the elongated protrusion 62 of the rear cap 50 is inserted into the support hole 64, and the fixing screw 54 is inserted into the mounting hole. The lower part of the rear cap 50 is fixed to the lower part of the reel body 12a by being tightened to the screw hole of the reel body 12a via 56. Further, the upper portion of the rear cap 50 is formed by screwing a fixing screw 68 inserted into a mounting hole 66 formed in the upper portion of the reel body 12a into a screw hole 62a opened at the tip of the protrusion 62, thereby Tighten and fix to.

  The anti-lifting portion 72 is prevented from coming off by the protrusion 62 of the rear cap 50 fixed by the fixing screw 68, and does not require a separate fixing screw. Moreover, since the fixing screw 68 for fixing the protrusion 62 is accommodated in the mounting hole 66 of the reel body 12a, it is not exposed to the outside. Since the lifting prevention portion 72 is held at an accurate position regardless of the tightening amount of the fixing screw 68, the lifting prevention portion 72 is fastened and fixed in a balanced manner along the peripheral portion of the lid body 12b with three fixing screws. Can do.

  The fishing spinning reel 10 formed in this way has a force acting via a rod attachment portion 12d fixed to the fishing rod when rotating the handle 22 in response to a large load acting via the fishing line, Due to the hoisting force acting via the handle 22, the lid body 12b tends to float from the reel body 12a. In this embodiment, such a force to float is generated by the three fixing screws respectively screwed into the screw holes 11 and the floating protrusions 62 of the rear cap 50 which is an engaging member. The rising prevention portion 72 is supported in a well-balanced manner along the peripheral portion of the lid 12b, and even if the structure is lightweight, a decrease in the rigidity of the reel body 12 is suppressed. Thereby, the fall of the efficiency at the time of winding operation can also be prevented reliably.

  Furthermore, by tightening the fixing screw 68, the reel body 12a, the lid 12b, and the rear cap 50 can be fixed at the same time, the work process can be simplified and the number of parts can be reduced, and the manufacturing cost can be reduced. Can do.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, It is possible to combine or change suitably according to various uses. For example, the through-hole 72a formed in the lifting prevention portion 72 may be formed by, for example, a U-shaped groove instead of the round hole as shown in the figure as long as it can be locked by the protrusion 62 of the rear cap 50. it can. Further, although the fixing protrusion 62 of the rear cap 50 is shared as an engaging member for locking the lifting prevention portion 72, it may be formed of a member independent of the rear cap 50.
