  The known fishing spinning reel described above employs a worm shaft system for the oscillating mechanism that converts the rotational movement of the handle into the reciprocating movement of the spool, and this worm shaft is located under the drive shaft on which the handle is mounted. Since it is installed between the front and rear parts in the side gear box, the reel body is enlarged.

  In this case, as a means for reciprocating the spool, an oscillating gear system capable of downsizing the reel body (a gear provided on the drive shaft is engaged with a slider that moves back and forth integrally with the spool shaft). Even if an attempt is made to adopt a method in which the rotation of the handle is converted into a longitudinal movement of the spool by meshing with the oscillating gear, a cam for operating the return mechanism is integrally provided at the end of the drive shaft. The reel body cannot be downsized. That is, even if an oscillating gear type idle gear is to be installed on the drive shaft, the reel is enlarged in the drive shaft direction (the axial direction becomes thicker) because the cam is arranged.

  The present invention has been made on the basis of the above-described problems, and includes a switching mechanism for switching the spool between a restricted state and a free state, and a return mechanism for returning the spool from the free state to the restricted state, thereby reducing the size of the reel body. An object is to provide a spinning reel for fishing.

  In order to achieve the above object, a fishing spinning reel according to the present invention is provided at a front portion of a reel body, and includes a spool around which a fishing line is wound, and a handle rotatably supported by the reel body. The rotor is rotatable through a pinion gear that meshes with a drive gear that is rotated by a winding operation, and a rotor that guides the winding of the fishing line around the spool via a fishing line guide, and the rotational movement of the handle is reciprocated back and forth of the spool. An oscillating mechanism having an oscillating gear to be converted, a switching mechanism having an operation member capable of switching between a restricted state for restricting rotation of the spool and a free state for making the spool free, and the switching in the spool free state A return mechanism that returns the mechanism to a restricted state by a winding operation of the handle, and a drive shaft on which the handle is mounted is A gear and a second gear are provided so as to be integrally rotatable. A return gear for operating the return mechanism and an oscillating gear are engaged with each of the first gear and the second gear, and a spool shaft inserted into the pinion gear is engaged. The meshing portion of the return gear is arranged on the drive gear side, and the meshing portion of the oscillating gear is arranged on the opposite side of the drive gear with respect to the spool shaft.

  In the fishing spinning reel having the above-described configuration, a return gear for operating the return mechanism with respect to the first gear and the second gear provided so as to be integrally rotatable on a drive shaft on which the handle is mounted, and an oscillating mechanism Each of the oscillating gears, and the return gear meshing portion is disposed on the drive gear side with respect to the spool shaft inserted through the pinion gear, and the spool gear is disposed on the opposite side to the drive gear. Since the meshing portion of the oscillating gear is arranged, the space in the reel body can be used efficiently, and the reel body can be miniaturized.

  According to the present invention, it is possible to reduce the size of a reel body of a fishing spinning reel that includes a switching mechanism that switches a spool between a restricted state and a free state, and a return mechanism that returns the spool from a free state to a restricted state. Become.

It is sectional drawing along CC line.

  A reel leg 1 of a spinning reel for fishing is integrally formed with a reel leg 1A to be attached to a fishing rod. A fishing line guide (not shown) is provided in front of the reel leg 1A, and the rotor is rotatably supported. 2 and a spool 3 that is supported so as to be movable back and forth in synchronization with the rotational motion of the rotor 2 and on which a fishing line is wound.

  A handle shaft (drive shaft) 4 is rotatably supported in the reel body 1 via a bearing 4a, and a handle 5 is attached to the protruding end portion. Further, a winding drive mechanism is engaged with the handle shaft 4, and this winding drive mechanism is attached to the handle shaft 4 and has a drive gear (face gear) formed with internal teeth (tooth portion 7a). 7 and a pinion gear 9 which meshes with the drive gear 7 and extends in a direction perpendicular to the handle shaft 4 and has a hollow portion extending in the axial direction therein. In this case, a recess 7b is formed on the radially inner side of the tooth portion 7a of the drive gear 7, and a part of the tooth portion of the first gear 15A, which will be described later, is provided in the recess 7b. It is configured to mesh with the gear 51.

  The pinion gear 9 is rotatably supported in the reel body via a bearing 9a, and is connected to rotate the rotor 2 integrally. A spool shaft 3a extending in a direction perpendicular to the handle shaft 4 and having the spool 3 mounted on the tip side is inserted into the hollow portion so as to be movable in the axial direction. When the handle 5 is driven to rotate, the spool shaft 3a is reciprocated back and forth by an oscillating mechanism 10 described later.

  The handle shaft 4 is provided with a first gear 15A and a second gear 15B coaxially and integrally rotatable. In the present embodiment, the first gear 15A and the second gear 15B are individually formed integrally with the handle shaft 4, and as shown in FIG. 3, with respect to the spool shaft 3a (its axis X). The drive gear 7 side and the reel main body side (the side opposite to the drive gear) are formed separately. The first gear 15 </ b> A and the second gear 15 </ b> B may be formed integrally with the handle shaft 4 without being separated, and in this case, the tooth portion only needs to be distributed with respect to the axis X.

  In the present embodiment, a part of the tooth portion of the first gear 15A is provided in a recess 7b formed on the radially inner side of the tooth portion 7a of the drive gear 7, as shown in FIG. In the recess 7b, a return gear 51, which will be described later, is disposed and meshed with the first gear 15A. The second gear 15B is engaged with an oscillating gear 14 of an oscillating mechanism 10 described later. For this reason, with respect to the spool shaft 3a inserted through the pinion gear 9, the meshing portion of the return gear 51 is positioned on the drive gear 7 side, and the meshing portion of the oscillating gear 14 is positioned on the opposite side of the drive shaft with respect to the spool shaft 3a. It is configured as follows.

  The oscillating mechanism 10 is configured by an oscillating gear system, and is attached to the rear end portion of the spool shaft 3a, and is engaged with the slider 12 in which a guide groove 12a is formed, and the guide groove 12a. And an oscillating gear (interlocking gear) 14 provided with an eccentric protrusion 14a.

  The oscillating gear 14 is meshed with the second gear 15B described above. When the handle 5 is rotated, the oscillating gear 14 is rotationally driven via the second gear 15B, and the slider 12 (spool 3 is reciprocated back and forth by the engagement relationship between the eccentric protrusion 14a provided on the oscillating gear 14 and the guide groove 12a.

  With the above-described configuration, when the handle 5 is wound up, the rotor 2 is rotationally driven via the drive gear 7 and the pinion gear 9, and the spool 3 reciprocates in the front-rear direction via the oscillating mechanism 10 described above. The fishing line is evenly wound on the spool 3 via the fishing line guide portion of the rotating rotor 2.

  A known drag mechanism (front drag mechanism) 17 is provided between the spool 3 and the spool shaft 3a to apply a braking force to the rotation of the spool (not shown). A sub-drag mechanism 20 is installed on the rear end side of the spool shaft 3a. When the spool 3 is in a free state (a state in which the spool shaft 3a rotates freely) by a switching mechanism which will be described later, an auxiliary is provided. A braking force (drag force) can be applied to the spool shaft 3a.

  Specifically, the sub-drag mechanism 20 includes an adjustment screw 21 that is rotated with respect to the cylindrical portion 1 a that is formed to protrude from the rear end of the reel body 1, and an axial movement that accompanies the rotation operation of the adjustment screw 21. Thus, a braking member 23 that can apply a predetermined braking force via the pressing spring 22 is provided. On the rear end side of the spool shaft 3a, a collar 24 is disposed through which a non-circular portion of the rear portion of the spool shaft 3a is inserted in a state of being non-rotatably fitted so as to be movable in the axial direction. Even when the braking force is applied between the main body 1 and the collar 24 and the spool shaft 3a can be freely rotated by the switching mechanism, the adjustment screw 21 is rotated to assist the rotation of the spool 3. It is possible to apply a braking force to.

  In the reel body 1, the switching mechanism 30 that switches between a restricted state that restricts the rotation of the spool 3 and a free state that makes the spool free, and the switching mechanism 30 that is in the spool free state are controlled by winding the handle 5. A return mechanism 50 for returning to the state is provided. Hereinafter, these mechanisms will be described.

  The “spool regulation state” in the present embodiment means a state in which the rotation of the spool shaft 3a is prevented and a desired drag force acts between the spool shaft 3a and the drag mechanism 17 or a spool lock state. The “spool free state” means that the spool shaft 3a is in a free rotation state. Accordingly, the spool free state includes a state in which a small rotational resistance is applied to the spool by the sub-drag mechanism 20.

  The switching mechanism 30 projects from the reel body 1 to the outside and is provided in the reel body 1 with a switching lever (operation member) 31 that can be rotated. And a stopper member 34 that is slidably driven along.

  The switching lever 31 is supported so as to be rotatable about the support shaft 31a with respect to the reel body 1, and a regulating piece 31b and a contact piece 31c are formed on the support portion of the switching lever 31. .

  A distribution holding spring 33 installed between the restriction piece 31b and the reel body 1 is connected, and the switching lever 31 is moved to the state shown in FIG. 1 (switching lever ON) and the spool free shown in FIG. It is arranged and held in the state (switching lever OFF). In this case, the restricting piece 31b abuts on a kick plate, which will be described later, in the state shown in FIG. 1 to restrict the rotation of the kick plate, and in the state shown in FIG. It comes to contact | abut to the inner surface.

  Further, when the switching lever 31 is rotated, the contact piece 31c contacts the contact portion 34a formed at the front end portion of the stopper member 34, and the kick piece 68 formed on the kick plate 60 described later. Will be kicked by.

  The stopper member 34 is supported by the reel body 1 so as to be able to move along the spool axis direction. The stopper member 34 is always rearward by a biasing spring 35 disposed between the stopper member 34 and the reel body 1. It is energized towards. An engagement / disengagement portion 34b is formed on the rear end side of the stopper member 34 so as to be engaged with and disengaged from the ratchet 3b fixed to the spool shaft 3a. In the state of being urged rearward by the urging force, the engagement / disengagement portion 34b engages with the ratchet 3b to prevent the spool shaft 3a from rotating.

  Further, a contact portion 34a is formed at the front end portion of the stopper member 34, and when the switching lever 31 is turned from the ON state shown in FIG. 1 to the OFF state shown in FIG. The stopper member 34 moves against the urging force of the urging spring 35 against the urging force 31c. In this case, when the stopper member 34 is moved forward, the engagement / disengagement portion 34b is detached from the ratchet 3b, so that the spool shaft 3a can be freely rotated (see FIG. 2).

  Then, the switching mechanism 30 switched to the spool free state is returned from the state shown in FIG. 2 to the state shown in FIG. Hereinafter, the configuration of the return mechanism 50 will be described.

  The return mechanism 50 includes a gear (return gear) 51 that meshes with a first gear 15 </ b> A provided integrally with the handle shaft 4, and a kick plate 60 that is driven as the return gear 51 rotates. ing.

  In this case, the return gear 51 meshes with the first gear 15A in the substantially opposite direction to the oscillating gear 14 that meshes with the above-described second gear 15B. Thus, transmission to the return gear 51 and the oscillating gear 14 is enabled. Moreover, the tooth | gear part 51a of the return gear 51 is arrange | positioned so that it may mesh | engage with the 1st gearwheel 15A in the recess 7b of the drive gearwheel 7 as mentioned above.

  The return gear 51 is supported so as to be rotatable with respect to the reel body 1, and a cam 51b is integrally formed on the same axis adjacent to the tooth portion 51a. In this case, as shown in FIGS. 1 and 2, the cam 51b is formed at two positions along the rotation direction at substantially 180 ° intervals, and the return gear 51 rotates in the clockwise direction in the state shown in FIG. When this is done, it can come into contact with the contact portion 61 formed at one end of the kick plate 60.

  A long hole 63 is formed in the kick plate 60, and a pin 65 attached to the reel body 1 is engaged with the long hole 63. Further, a tension spring 67 is disposed between the kick plate 60 and the reel body 1, and the kick plate 60 is constantly biased counterclockwise around the pin 65. ing. In this case, in the ON state shown in FIG. 1, the kick plate 60 is restricted from rotating by the tension spring 67 by the restriction piece 31 b of the switching lever 31 described above. That is, the kick plate 60 tries to rotate counterclockwise around the pin 65 by the urging force of the tension spring 67, but the rotation is restricted by the restricting piece 31b. .

  A kick piece 68 is bent at the other end of the kick plate 60 so that when the kick plate 60 is driven by the cam 51b, the contact piece 31c of the switching lever 31 described above is kicked. It has become.

  The operation of the fishing spinning reel constructed as described above will be described.

  Initially, as shown in FIG. 1, the switching mechanism 30 is in an ON state. In this state, since the engaging / disengaging portion 34b of the stopper member 34 is engaged with the ratchet 3b, the spool shaft 3a is in a fixed state, and a desired drag force is applied to the spool 3 via the front drag mechanism 17. It will be in the state which acted.

  When the switching lever 31 is turned in the direction of the arrow from the state shown in FIG. 1, the contact piece 31c is rotated clockwise about the support shaft 31a, and comes into contact with the contact portion 34a of the stopper member 34. The stopper member 34 is shifted to the spool side against the biasing force of the biasing spring 35. At this time, as shown in FIG. 2, the engaging / disengaging portion 34b of the stopper member 34 is detached from the ratchet 3b, and the spool shaft 3a (spool 3) is in a freely rotatable state. This state is held by the distribution holding spring 33.

  As a result, the spool 3 is in a completely free state, so that when a fish is caught, the fishing line can be pulled out as it is. In this state, a drag force can be supplementarily applied to the rotation of the spool 3 by rotating the adjusting screw 21 of the sub-drag mechanism 20 described above.

  Further, the restricting piece 31b is separated from the kick plate 60 by the turning operation of the switching lever 31 in the direction of the arrow, and the restriction is released. Therefore, the kick plate 60 is centered on the pin 65 by the tensile force of the tension spring 67. As counterclockwise. As a result, as shown in FIG. 2, the contact portion 61 formed at one end portion of the kick plate 60 enters the rotation locus of the cam 51 b of the return gear 51.

  In this state, if the rotor 2 is set in a reversible state, the handle shaft 4 (the gear 15) rotates clockwise in FIG. 2 when a fish is caught. At this time, although the return gear 51 rotates in the counterclockwise direction, the circular arc surface 51c formed around the cam 51b is in sliding contact with the kick plate 60, thereby affecting the operation of the switching mechanism 30 and the return mechanism 50. Never give.

  In the state shown in FIG. 2, when the handle 5 is wound up, the gear 15 rotates counterclockwise, and the return gear 51 (cam 51b) rotates clockwise. Accordingly, the kick plate 60 is moved rearward against the urging force of the tension spring 67 by the cam 51b (moved rearward due to the engagement relationship between the long hole 63 and the pin 65) and the other end. The kick piece 68 formed on the portion kicks the contact piece 31c of the switching lever 31.

  Thereby, the switching lever 31 is rotated counterclockwise about the support shaft 31a, and is returned to and held in the state shown in FIG. Further, since the contact piece 31 c is detached from the contact portion 34 a of the stopper member 34 by the rotation of the switching lever 31, the stopper member 34 is shifted rearward by the biasing force of the biasing spring 35. As a result, the engagement / disengagement portion 34b of the stopper member 34 is engaged with the ratchet 3b, and is again switched to the restricted state where the rotation of the spool 3 is restricted.

  The fishing spinning reel having the above-described configuration employs an oscillating gear system as a mechanism for reciprocating the spool 3 back and forth, so that the reel body 1 can be downsized.

  A return gear 51 that operates the return mechanism 50 with respect to the first gear 15A and the second gear 15B that are provided on the handle shaft 4 on which the handle 5 is mounted so as to be integrally rotatable, and the oscillation that constitutes the oscillation mechanism 10. Each of the gears 14 is meshed, and the meshing portion of the return gear 51 is disposed on the drive gear 7 side with respect to the spool shaft 3a inserted through the pinion gear 9, and is oscillated on the opposite side of the drive gear 7 with respect to the spool shaft 3a. Since the meshing portion of the gear 14 is disposed, the space in the reel body 1 can be used efficiently, and the reel body 1 can be reduced in size and weight.

  In particular, in the present embodiment, the first gear 15A is positioned in the recess 7b of the drive gear 7, and the meshing portion with the tooth portion 51a of the return gear 51 is disposed here. In addition, the return gear 51 can be efficiently installed in a limited space, and the reel body 1 can be further reduced in size (thinned) and reduced in weight.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously.

  The present invention relates to a fishing spinning reel including a gear oscillation type oscillating mechanism 10 and a switching mechanism 30 for switching between a restricted state for restricting the rotation of the spool 3 and a free state for making the spool free. The meshing portions of the return gear 51 and the oscillating gear 14 that operate the return mechanism 50 that automatically returns to the restricted state by the take-off operation are spooled with respect to the first gear 15A and the second gear 15B provided on the handle shaft 4. It has the characteristic in arrange | positioning so that it may distribute with respect to the axis | shaft 3a, About other structures, it can deform | transform suitably.

  For example, the configuration and operation direction of the stopper member 34, the mutual engagement relationship and arrangement of the switching lever 31, the stopper member 34, and the kick plate 60 are not limited to the above-described embodiment, and may be modified as appropriate. Is possible. Further, the first gear 15A and the second gear 15B provided on the handle shaft 4 may be provided separately on the handle shaft 4 so as to be integrally rotatable.
