Description

  The present invention relates to a fishing spinning reel that winds a fishing line around a spool via a fishing line guide provided on a rotor portion that rotates in conjunction with a rotation operation of a handle.

  Usually, a fishing spinning reel includes a rotor provided with a fishing line guide and a spool around which a fishing line is wound, and simultaneously rotates the rotor by rotating a handle and simultaneously reciprocates the spool. It has a configuration. The rotor is formed with a pair of arm portions facing each other on both sides of the rear portion of the cylindrical main body portion, and the fishing line is connected to the spool that moves back and forth via the fishing line guide portion provided on one arm portion. Is to be wound.

  In the fishing spinning reel having the above-described structure, when a fish hits and the handle is wound up, a large load is applied to the fishing line (during winding operation when a heavy load is applied, In such a case, the rotor arm portion is deformed radially inward, and depending on the situation, the inner surface of the arm portion may hit the outer periphery of the skirt of the spool. Further, when the drag is fed out, there is a problem that pulsation occurs due to the deformation of the arm portion, and the smooth fishing line cannot be fed out.

  Therefore, for example, Patent Document 1 discloses a fishing spinning in which a belt-shaped reinforcing member is bridged in a circular arc shape on the fishing line discharge position side at a predetermined distance from the outer periphery of the rotor on the distal end side of the pair of arm portions. A reel is disclosed.

Japanese Patent No. 2894422

However, in the fishing spinning reel disclosed in Patent Document 1, the reinforcing member is disposed between the tip ends of the pair of arm portions at a predetermined distance from the outer periphery of the cylindrical portion of the rotor so as to surround a part of the outer periphery of the spool. Since the structure is constructed in the shape of an arc, the weight is biased toward the front side of the rotor, and therefore it is difficult to achieve an efficient weight balance. Further, since the reinforcing member is arranged on the outer peripheral side of the spool for winding the fishing line, the fishing line is easily entangled with the reinforcing member, and the reinforcing member is in the way and it is difficult to lock the fishing line to the line holder.
Further, in the fishing spinning reel disclosed in Patent Document 1, the arm portion has a thick-walled base portion due to the reinforcing member being erected on the distal end side. However, the inertial force is increased due to the weight of the rotor, and the rotor rotation / stop operation sensitivity is poor, and it cannot respond sensitively to fish shin (inferior fishing operability).

  The present invention has been made by paying attention to the above-described problem, and can sufficiently reinforce the arm portion without hindering fishing line operation, and can achieve weight reduction of the entire rotor and has excellent weight balance. An object is to provide a spinning reel.

  In order to achieve the above-described object, a fishing spinning reel according to the present invention has a rotor fixed to a drive shaft that rotates in conjunction with a rotation operation of a handle provided on a reel body, and the rotor includes: A fixed portion fixed to the drive shaft; and a pair of arm portions formed to face both sides of the fixed portion and projecting forward; The member is constructed and fixed from outside or inside of one arm part to outside or inside of the other arm part.

  According to the fishing spinning reel having the above-described configuration, the reinforcing member separate from the rotor is constructed and fixed from the outside or inside of one arm portion to the outside or inside of the other arm portion. Even if a large load is applied to the part, stress can be dispersed by the reinforcing member, and the arm part can be effectively reinforced and prevented from being deformed, and unnecessary while reducing the weight of the entire rotor. Incurring weight can be avoided. Further, since the reinforcing member has a substantially annular shape, it is possible to avoid an uneven weight of the rotor and to achieve an efficient weight balance (a good balance of rotation of the rotor). Furthermore, since the reinforcing member is disposed not on the outer peripheral side of the spool but around the arm portion, there is no possibility that the fishing line may get entangled with the reinforcing member. Therefore, the fishing line operation is not hindered. In addition, because the rotor can be made as light as possible, the inertia of the rotor can be reduced, and the operation sensitivity of the rotation and stop of the rotor can be improved, making it possible to respond sensitively to changes in the tension of the fishing line. , Fish confidence sensitivity is improved significantly (fishing operability is improved).

  ADVANTAGE OF THE INVENTION According to this invention, while being able to fully reinforce an arm part, without inhibiting fishing line operation, the spinning reel for fishing excellent in the weight balance which can achieve weight reduction of the whole rotor is obtained.

The spool 5 is provided.

  As is well known, a handle shaft 73 on which the handle 2 is mounted is rotatably supported in the reel body 1 via a bearing, and the handle shaft 73 can be operated to rotate the handle 2 by the rotor. 3 and a power transmission mechanism 75 for transmission to the spool 5 is engaged.

  In this case, the power transmission mechanism 75 includes a drive gear 72 that is mounted on the handle shaft 73 so as to be integrally rotatable, and a rotary shaft cylinder (drive shaft) 8 that extends in a direction orthogonal to the handle shaft 73. And. A pinion 8 a that meshes with the drive gear 72 is formed on the rear side of the rotary shaft cylinder 8, and the rotor 3 is rotated by screwing a rotor nut 9 at the tip, as will be described later. It is attached to the shaft tube 8.

  In addition, a spool shaft 5a holding the spool 5 around which the fishing line is wound is inserted into the rotary shaft cylinder 8 at the front. A known oscillating mechanism 80 is connected to the spool shaft 5a, and when the handle shaft 73 is rotated by a rotation operation of the handle 2, the spool shaft 5a is driven back and forth in the axial direction.

  With the above-described configuration, by rotating the handle 2, the rotor 3 is rotationally driven via the power transmission mechanism, and the spool 5 is reciprocated back and forth via the oscillating mechanism. The fishing line is wound evenly around the fishing line winding body 5 b of the spool 5 via the fishing line guide 15 provided in the rotor 3.

Next, the configuration of the rotor 3 will be described.
The rotor 3 includes a plate-like fixing portion 20 that is fixed to the rotating shaft cylinder (drive shaft) 8 and a pair of arm portions 22 and 22 that are formed to protrude radially outward on both sides of the fixing portion 20. And have.

  The fixing portion 20 is a portion that is fixed to the rotating shaft cylinder 8 by the rotor nut 9. In this embodiment, as shown in FIG. 5, a region that extends in a direction orthogonal to the axial direction and has a predetermined area. It is configured as. Specifically, the fixing portion 20 of the present embodiment is configured to be flat so that the rotor 3 can be fixed to the rotary shaft cylinder 8 by a fixing member such as the rotor nut 9, and an opening 20 a is formed in the center portion thereof. Then, by inserting the rotary shaft cylinder 8 here and screwing the rotor nut 9, the rotor 3 is fixed to the rotary shaft cylinder 8. The center of the fixed portion 20 (the central region of the opening 20a) is a portion through which the spool shaft 5a is inserted.

  On the other hand, each arm part 22 and 22 is comprised so that it may protrude to radial direction outward from the periphery of the fixing | fixed part 20, and it is radial direction (approximately 180 degrees) centering | focusing on the rotating shaft cylinder 8 penetrated in this embodiment. A pair is formed so as to extend at an interval. Specifically, each of the arm portions 22, 22 extends rearward along the axial direction from both sides of the plate-like fixing portion 20, extends radially outward, and then extends forward again along the axial direction. Accordingly, the rotary shaft cylinder (drive shaft) 8 is positioned so as to face the both sides of the rotary shaft cylinder (drive shaft) substantially in parallel. In addition, as will be described later, these arm portions 22 are directed from the front to the rear so as to surround the fixed portion 20 from the outside or inside of one arm portion 22 to the outside or inside of the other arm portion 22. A belt-shaped reinforcing member 25 that is separate from the rotor 3 that is formed in a substantially annular shape when viewed is fixed.

  Further, as described above, the pair of arm portions 22, 22 are formed so as to protrude from the peripheral edge of the fixed portion 20 toward the rear side, and thus, between the pair of arm portions 22, the rotor 3. An open portion S is formed on the rear side of the fixed portion 20 (see FIG. 4 and the like). That is, the rear portion of the fixed portion 20 of the rotor 3 has an opening (opening portion S) having no peripheral wall on the side facing the reinforcing member 25. In the open portion S, a cylindrical portion (cap) 1A that protrudes forward from the reel body 1 is arranged. In this case, a part of the power transmission mechanism 75 described above is accommodated in the cylindrical portion 1A. Thereby, the reel main body 1 is made compact.

  The reinforcing member 25 is installed so as to surround the fixing portion 20 from the outer side or the inner side of the one arm portion 22 projecting radially outward to the fixing portion 20 to the outer side or the inner side of the other arm portion 22. It is a substantially annular belt-like member to be fixed. In particular, in this embodiment, the reinforcing member 25 is installed and fixed from the outside of one arm portion 22 to the outside of the other arm portion. As shown in FIG. 5, the annular shape may be any shape that surrounds the fixed portion 20 via a predetermined gap when the rotor 3 is viewed in plan view. Considering it, it is formed in an elliptical shape when viewed in plan. However, the shape, such as an elliptical shape or a circular shape close to a circle, is not specified, and can be changed as appropriate.

  In addition, a mounting portion 26 that extends toward the front and can be mounted on the arm portion 22 is formed in a part of the reinforcing member 25. Specifically, as shown in FIG. 5, a pair of mounting portions 26 of the present embodiment are provided on both sides of the reinforcing member 25 with an angular interval of approximately 180 degrees, and the reels are attached to the arm portion 22 in the attached state. It is formed in the front side edge part of the curved part 25b of the reinforcement member 25 which curves in the circular arc shape so that it may become convex toward the main body 1 side. The curved portion 25b extends in an arc shape forward while curving from the rear end base portion 25a of the reinforcing member 25 corresponding to the convex apex so as to connect the mounting portions 26 and 26 to each other. . For this reason, when FIG. 4 is viewed from the direction rotated by 90 °, as shown in FIGS. 2 and 3, the mounting portion 26 gradually approaches the front end portion of the curved portion 25 b of the reinforcing member 25 as it moves forward. The rear side of both mounting portions 26 that are formed to face each other is in an open state (a state in which the gap portion S1 is formed). Note that the opening forming the gap S1 is the widest at the rear end base portion 25a (opening width L: see FIG. 3) when viewed from the side, and gradually becomes narrower as it moves forward. . That is, the reinforcing member 25 attached to the arm portion 22 is formed in a substantially C-shape that expands toward the rear side.

  In the present embodiment, the support member 16 is rotatably supported on the front portion of the arm portion 22 to which the reinforcement member 25 is mounted, and the reinforcement member 25 is detachably fixed to the support portion. It has become so. Specifically, for example, the mounting shaft portion 22A protrudes radially outward from the front end portion of each arm portion 22, and a screw hole 22a is formed in the mounting shaft portion 22A to support the mounting shaft portion 22A. By screwing the screw member 30 into the screw hole 22a from the mounting hole 26a side while being inserted into the mounting hole 16a of the member 16 and the mounting hole 26a of the mounting portion 26 of the reinforcing member 25, the support member 16 and the reinforcing member 25 are engaged. (Mounting portion 26 of reinforcing member 25) is collectively mounted on arm portion 22. Such a mounting form can be appropriately modified. For example, each mounting part 26 may be attached to the inner side of the arm part 22 in the radial direction.

  In addition, the bail 17 which picks up a fishing line is attached to the rotatable support member 16, and the fishing line guide part 15 is provided on one base side of the bail 17. The support member 16 rotates between the fishing line release position where the fishing line is removed from the fishing line guide section 15 and the fishing line winding position where the fishing line is picked up via the bail 17 and guided to the fishing line guide section 15. It is possible to move. That is, it is possible to easily return to the state of winding the fishing line after releasing the fishing line.

  Further, in the present embodiment, as shown in FIG. 4, the support member 16 is placed between the fishing line winding position and the fishing line release position in one arm part 22 (arm part 22 on the fishing line guide part 15 side). A sorting and holding mechanism for sorting and holding is provided. This sort and hold mechanism has a configuration in which an arc-shaped groove is formed around the rotating portion of the support member 16 and a projection that fits into the groove is formed on the arm portion 22. Then, the support member 16 is engaged with one end 37 a of an engagement portion that engages with a known distribution holding spring 37, and the other end 37 b is fixed in the arm portion 22. It is possible to distribute and hold between the fishing line winding position and the fishing line discharge position.

  That is, when the support member 16 is in the fishing line winding position shown in FIGS. 1, 2, and 3, the support member 16 receives a counterclockwise force by the urging force of the sorting holding spring 37, but the protrusion is The position is maintained by applying to one end of the groove. Then, when the support member 16 is rotated clockwise by the angler's hand, the force is applied in the clockwise direction by the biasing force beyond the dead point of the sorting holding spring 37, but the other end of the groove The position (fishing line release position) is held by the projection being applied.

  In the present embodiment, the support member 16 in the fishing line discharge position is reversed in the other arm portion 22 as a switching control member that automatically returns to the fishing line winding position by the rotation of the handle 2 (rotation of the rotor 3). A kick member 65 is disposed. As shown in FIG. 4, one end of the reverse kick member 65 is engaged with the arc-shaped groove of the support member 16, and the other end 65 a is positioned in the opening 22 b at the bottom (rear end) of the arm portion 22. When the support member 16 is rotated from the fishing line winding position to the fishing line release position, one end of the reverse kick member 65 comes into contact with the end surface of the arc-shaped groove, and the other end 65a of the reverse kick member 65 is reached. Is pushed outward from the opening 22b of the arm portion 22. When the rotor 2 is rotated by rotating the handle 2 from this state, the other end 65a of the reverse kick member 65 protruding from the opening 22b is brought into contact with a projection (not shown) protruding from the front surface of the reel body 1. The arm portion 22 is pushed back along the guide surface of the protrusion. Thereby, one end of the reversal kick member 65 reversely returns the support member 16 to the fishing line winding position via the end surface of the arc-shaped groove.

  According to the spinning reel for fishing having the above-described configuration, the reinforcing member 25 that is separate from the rotor 3 is installed and fixed from the outside or inside of one arm portion 22 to the outside or inside of the other arm portion 22. Even if a large load is applied to the arm portion 22 due to the tension of the arm portion 22, stress can be dispersed by the reinforcing member 25, and the arm portion 22 can be effectively reinforced and prevented from being deformed, and the entire rotor 3 can be prevented from being deformed. It is possible to avoid unnecessarily increasing the weight while reducing the weight. Further, since the reinforcing member 25 has a substantially annular shape, it is possible to avoid an uneven weight of the rotor 3 and to achieve an efficient weight balance (a good rotational balance of the rotor 3). Furthermore, since the reinforcing member 25 is disposed not on the outer peripheral side of the spool 5 but around the arm portion 22, there is no possibility that the fishing line may be entangled with the reinforcing member 25. Therefore, the fishing line operation is not hindered. Further, since the rotor 3 can be reduced in weight as much as possible, the inertia (inertia) of the rotor is reduced, the operation sensitivity of the rotation and stop of the rotor 3 is improved, and the tension of the fishing line is sensitive. It can react and fish sensitivity is improved significantly (fishing operability is improved).

  In this embodiment, the support member 16 and the reinforcing member 25 can be simultaneously attached to the arm portion 22 at the same time, so that the assemblability is good (the number of assembling steps is small and the manufacturing cost can be reduced). Become). In the present embodiment, since the rear portion of the fixing portion 22 of the rotor 3 forms the open portion S on the side facing the reinforcing member 25, the rotor 3 can be further simplified and reduced in weight. Become.

  Further, in this embodiment, since the cylindrical portion 1a of the reel body 1 in which various functional parts are installed is disposed between the pair of arm portions 22, the weight of the rotor 3 is reduced while making the reel body 1 compact. It is possible to reduce the weight as much as possible.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously. For example, the shape of the fixed portion 20, the width of each arm portion 22, the protruding length, and the connection mode between the arm portion 22 and the reinforcing member 25 can be appropriately modified. Moreover, about the whole shape of the reinforcement member 25 comprised in cyclic | annular form, you may comprise a curved part, a linear part, etc. in combination, or may comprise only a curved part, About structures, such as the thickness and width, Further, it may be configured symmetrically with the spool 5 interposed therebetween, or may be appropriately modified such as asymmetrical. Further, the reinforcing member 25 may be configured in a hollow shape. Further, the cross-sectional shape of the reinforcing member 25 can be appropriately modified such as circular, oval, rectangular, etc., and various patterns are formed on the surface thereof, for example, in order to improve the appearance. Or surface treatment. Further, there may be a part formed in a cylindrical shape by the fixing part 20 and the pair of arm parts 22. Furthermore, the screw member 30 for attaching the reinforcing member 25 and the support member 16 to the arm portion 22 may be tightened from the radially inner side of the arm portion 22, as shown in FIG. The material used for the rotor 3 and the reinforcing member 25 is appropriately selected from metal, resin, FRP, and the like, but the plate-like portions such as the fixed portion 20 and the pair of arm portions 22 and 22 of the rotor 3 are made of carbon. It is possible to reduce the weight as much as possible by combining and forming the woven fabric sheet by laminating and forming the reinforcing member 25 with resin and FRP.
