Description

  The present invention relates to a fishing reel provided with a backlash prevention device for preventing over-rotation when releasing a fishing line of a spool rotatably supported between side plates of a reel body.

  Conventionally, when a fishing line is released (for example, when casting), if the spool rotation speed becomes faster than the fishing line withdrawal speed (over-rotation), a backlash phenomenon occurs, causing problems such as entanglement and biting. A casting reel is equipped with a backlash prevention device for automatically preventing such a spool over-rotation phenomenon.

  Usually, the backlash prevention device is configured to apply a braking force to the rotation of the spool. For example, a magnetic braking device using a magnetic force as disclosed in Patent Document 1 is known. In this magnetic braking device, a conductor that rotates integrally with a spool is positioned in a magnetic field formed by a magnet, and a braking force is applied to the rotation of the conductor by an electromagnetic force that is generated along with the rotation of the conductor. A braking force is applied to the spool that rotates integrally with the body.

  Specifically, the magnetic braking device disclosed in Patent Document 1 is unnecessary at the casting initial stage and the final stage by causing the conductor to advance and retreat against the biasing force in the magnetic field according to the rotation speed of the spool during casting. The spool rotation is eliminated to improve the flight distance, and the conductor that moves in the axial direction in accordance with the rotation speed of the spool can be selected between an operating state and a non-operating state.

FIG. 1 is a plan view showing an internal configuration, FIG. 2 is an enlarged view showing a configuration of a magnetic braking device portion, and FIG. 2 is an enlarged view showing a state in which the magnet is moved from the state shown in FIG. 2, FIG. 4 is a view schematically showing the cam action in the configuration shown in FIGS. 2 and 3, and FIG. It is sectional drawing (a bearing is abbreviate | omitted) along the AA line.

  As shown in FIG. 1, a dual-bearing type reel 1 as a fishing reel according to this embodiment includes left and right side plates 1a and 1b and left and right frames 2a and 2b covered with both side plates 1a and 1b. It has a reel body. A spool shaft 5 is rotatably supported between the left and right frames 2a and 2b via a bearing 7, and a spool 5a around which a fishing line is wound is integrally fixed to the spool shaft 5.

  A pinion gear 8 that is movable along the axial direction of the spool shaft 5 is attached to the end of the spool shaft 5 that protrudes from the right frame 2b. The pinion gear 8 is released from an engagement position (power transmission state) where the pinion gear 8 is engaged with the spool shaft 5 and rotates together with the spool shaft 5 by a known switching means (not shown) and the engagement state with the spool shaft 5. And the disengaged position (power cut off state). A drive gear 12 meshes with the pinion gear 8, and a handle 9 a is attached to an end of the handle shaft 9 attached to the drive gear 12. Therefore, when the handle 9a is rotated, the spool shaft 5 is rotationally driven via the drive gear 12 and the pinion gear 8, and the spool 5a is rotated accordingly.

  Further, a known level wind device 10 is disposed between the left and right frames 2a and 2b on the fishing line feeding direction side of the spool 5a. The level wind device 10 is configured such that the fishing line guide 11 through which the fishing line is inserted moves left and right by rotating the handle 9a, and the fishing line is evenly distributed to the spool 5a as the fishing line is wound up. Wind.

  Further, in the present embodiment, a magnetic braking device 20 is provided on the left side plate side to prevent the spool 5a from over-rotating during the fishing line releasing operation.

  The magnetic braking device 20 includes a cylindrical moving body 22 that is disposed on the outer peripheral surface of the spool shaft 5 and that can move along the axial direction and is fitted in a non-rotating manner. On the outer peripheral surface of the moving body 22, a notch-shaped support member 22a formed by extending in the radial direction at a predetermined interval is formed, and each support member 22a is movable in the radial direction. Thus, the centrifugal collar (radial direction moving member) 23 is supported. When the spool shaft 5 (and the moving body 22) rotates together with the spool 5a, the centrifugal collars 23 move radially outward with respect to the support member 22a by centrifugal force.

  An annular conductor 30 is supported on one side of the centrifugal collar 23 (on the left frame 2a side). The conductor 30 is movable in the axial direction with respect to the spool shaft 5 as the movable body 22 moves.

  A taper surface 5b is formed on the back surface side of the fishing line winding surface of the spool 5a as an axial direction conversion control section that gradually increases in diameter toward the left frame 2a. The tapered surface 5b is in surface contact (engagement) with the inclined surface 23a formed on the outer surface of the centrifugal collar 23 and guides the movement of the centrifugal collar 23 when the centrifugal collar 23 moves radially outward. It is like that. That is, the centrifugal collar 23 supported by the support member 22a of the moving body 22 is moved in the radial direction by the engaging action with the inclined surface 23a due to the centrifugal force accompanying the rotation of the spool shaft 5 (spool 5a) and is tapered. The moving body 22 guided along the surface 5b and supporting the annular conductor 30 is moved in the axial direction toward the left frame 2a (the radial movement of the centrifugal collar 23 is caused by the movement of the moving body 22). Converted to axial movement).

  Further, between the retainer 26 fixed to one end of the spool shaft 5 and the moving body 22, the moving body 22 is always urged toward the spool 5a (the conductor 30 is magnetized by a magnet described later). A spring member 27 (which is always urged toward the spool 5a in the direction away from the center) is inserted.

  Further, the magnetic braking device 20 is provided with a magnet 40 that is disposed on the left side plate 1a constituting the reel body and that exerts a magnetic force between the conductor 30 that is movable in the axial direction. The magnet 40 may be configured to apply a magnetic force to the conductor 30 that advances and retreats in the axial direction in accordance with the rotation of the spool 5a so as to apply a braking force to the conductor 30. An inner magnet 41 that is annularly formed and opposed to the inner surface side of the conductor 30 with a predetermined interval; and an outer magnet that is annularly disposed and disposed on the outer surface side of the conductor 30 with a predetermined interval. And a magnet 42. That is, the conductor 30 can advance and retreat in a magnetic field generated in a gap between the inner magnet 41 and the outer magnet 42, and applies a magnetic braking force to the spool 5a. The magnets 41 and 42 are attached to the holders 45 and 46 via yokes (not shown) for magnetic shielding.

  The annular magnet 40 is held by an axial movement holding mechanism 50 so as to be movable in the axial direction. Hereinafter, a configuration example of the axial movement holding mechanism 50 will be described.

  The axial movement holding mechanism 50 has a support plate 51 mounted on the left side plate 1a, and a shaft with respect to the outer periphery of the support portion 51a that is formed on the support plate 51 so as to surround the left end portion of the spool shaft 5. And a magnet holder 53 that is fitted to prevent rotation so as to be movable in the direction. In this case, the magnet holder 53 includes an inner annular wall 53a and an outer annular wall 53b, and the inner annular wall 53a is fitted to the support portion 51a so as to be able to move in the axial direction. . The inner magnet 41 is attached to the outer periphery of the inner annular wall 53a with a holder 45 interposed, and the outer magnet 42 is rotatable on the inner peripheral side of the outer annular wall 53b with a holder 46 interposed. It is arranged.

  The inner annular wall 53a is formed with an annular recess (notch) 54 that opens toward the spool side, and a biasing spring 55 between the retainer 51c attached to the tip of the support portion 51a. The magnet holder 53 is urged in the direction opposite to the spool. The inner annular wall 53a is formed with a spiral cam surface 56 that opens toward the anti-spool side and is annular and has a height difference along the circumferential direction.

  Further, a knob (first knob) 60 is rotatably mounted on the support plate 51 so as to enter the opening edge 1a ′ of the left side plate 1a attached to the support plate so as to be exposed to the outside. Yes. The first knob 60 is imparted with a moderation in the rotational direction by a biasing member 62 (configured by an engagement pin and a spring) interposed between the support plate 51, and a flange 60a is provided at the opening edge 1a '. It is secured by facing each other. Further, the first knob 60 is integrally formed with an engaging projection 60b that engages with the helical cam surface 56 having the above-mentioned height difference. The cam surface 56 and the engaging projection 60b are The engagement relationship is always maintained by the urging force of the urging spring 55.

  With the above-described configuration, by rotating the first knob 60, the magnet holder 53 is attached to the biasing spring 55 by the action of the cam surface 56 and the engaging protrusion 60b as schematically shown in FIG. It can be moved (in the direction of the arrow) to the spool side along the axial direction against the urging force. Further, by rotating the first knob 60 in the reverse direction, the magnet holder 53 is made to react along the axial direction by the action of the cam surface 56 and the engagement protrusion 60b and the biasing force of the biasing spring 55. It can be moved to the spool side. In this case, by moving the magnet holder 53 along the axial direction, the overlapping area of the inner magnet 41 and the outer magnet 42 attached to the conductor 30, that is, the initial setting position can be changed. It is possible to adjust the initial magnetic braking force and the final magnetic braking force acting on the conductor 30 positioned at the position. FIG. 3 shows a state where the magnet holder 53 is moved to the spool side along the axial direction.

  In the present embodiment, among the magnets 40 held by the magnet holder 53, the outer magnet 42 (holder 46) is configured to be rotatable. Specifically, a gear 70 is attached to the outer peripheral surface of the holder 46 to which the outer magnet 42 is attached (may be integrally formed on the outer periphery of the holder 46), and the outer annular wall 53b of the magnet holder 53 is also provided. In addition, an opening 53d extending in the axial direction is formed, and the intermediate gear 71 rotatably supported by the support plate 51 is meshed with the opening 53d.

On the other hand, a knob (second knob) 75 is rotatably mounted on the support plate 51 so as to be exposed to the outside. The second knob 75 is disposed so as to penetrate the support plate 51, is prevented from being detached by the retainer 76, and is biased by an urging member 77 (composed of an engagement pin and a spring) interposed between the second tab 75 and the support plate 51. Moderation is given in the direction of rotation. An input gear 72 that meshes with the intermediate gear 71 is attached to the inner end of the second knob 75 in the axial direction.

  With the above-described configuration, by rotating the second knob 75, the gear 70, that is, the outer magnet 42 can be rotated by the above-described gear coupling structure as schematically shown in FIG. In this case, since the polarity relationship (NN, NS) changes with the inner magnet 41 by rotating the outer magnet 42, the magnetic braking force acting on the conductor 30 positioned therebetween is changed. It becomes possible to adjust.

  Next, the operation of the dual bearing type reel 1 having the above-described configuration will be described.

  For example, when the spool 5a rotates by casting, the moving body 22 also rotates integrally with the spool 5a. Since the centrifugal force acting on the centrifugal collar 23 is weak until the rotational speed of the spool 5a reaches a predetermined magnitude immediately after the start of casting, the pressing force of the centrifugal collar 23 on the tapered surface 5b of the spool 5a is weak. Is smaller than the biasing force of the spring member 27. Therefore, as shown in FIG. 2, the moving body 22 hardly moves in the axial direction with respect to the spool shaft 5, and the conductor 30 attached to the moving body 22 is between the inner magnet 41 and the outer magnet 42. It does not rush into the annular space formed in.

  Thereafter, when the rotational speed of the spool 5a increases and the centrifugal force acting on the centrifugal collar 23 exceeds a predetermined magnitude, that is, the axial component of the pressing force of the centrifugal collar 23 against the tapered surface 5b of the spool 5a is springed. When it becomes larger than the urging force of the member 27, the moving body 22 starts to move relative to the spool shaft 5 against the urging force of the spring member 27 due to the engagement guide action of the centrifugal collar 23 and the tapered surface 5 b. Then, when the conductor 30 enters the annular space (magnetic field) formed between the inner magnet 41 and the outer magnet 42 by this movement, the conductor 30 enters the penetration amount (movement amount) and the rotation speed. The force corresponding to is received from the magnetic field. Accordingly, the braking force associated with this force also acts on the spool 5 a that rotates integrally with the conductor 30. In other words, the magnetic braking force corresponding to the rotational speed of the spool 5a can be increased or decreased. As a result, the spool 5a is prevented from over-rotating and the backlash phenomenon is suppressed.

  Further, at the end of casting, when the rotational speed of the spool 5a decreases and the centrifugal force acting on the centrifugal collar 23 becomes weak, that is, the axial component of the pressing force of the centrifugal collar 23 against the tapered surface 5b of the spool 5a becomes a spring. When it becomes smaller than the urging force of the member 27, the moving body 22 starts to return toward the initial position by the urging force of the spring member 27. Thereby, the conductor 30 gradually escapes from the annular space (magnetic field) formed between the inner magnet 41 and the outer magnet 42, and the force received from the magnetic field gradually decreases. Therefore, at the end of casting, an appropriate braking force can be applied to the spool and the back 8 lash can be effectively prevented without unnecessarily reducing the flight distance.

  Since the magnetic braking device 20 configured as described above can change the initial setting positions of the inner magnet 41 and the outer magnet 42 by the axial movement holding mechanism 50, the braking characteristics are optimal. It becomes possible to set the state.

  For example, by rotating the first knob 60, as shown in FIG. 3, the tip region of the conductor 30 is in an annular space (magnetic field) formed between the inner magnet 41 and the outer magnet 42 at the initial position. If it is set in a state where it has entered, it becomes possible to increase the braking force acting on the spool 5a at the initial stage or the final stage of casting, as compared with the initial setting state shown in FIG. As a result, it is possible to change and set the braking characteristics from the initial to the middle and the middle to the end of the rotation of the spool 5a, so it can be widely used from short cast to long cast according to various changes in the fishing grounds. It becomes possible to do.

  In the present embodiment, the second magnet 75 is rotated to rotate the outer magnet 42, thereby changing the polarity relationship (NN, NS) with the opposing inner magnet 41. It is possible to make it. For this reason, since the magnitude | size of the magnetic field formed between the inner magnet 41 and the outer magnet 42 can be adjusted, in addition to the above-mentioned movement adjustment of the magnet 40 in the axial direction, a wider change in braking characteristics is possible.・ Setting is possible.

Next, another embodiment of the present invention will be described.
FIG. 6 is a diagram showing a second embodiment of the present invention. The magnet holder 53 </ b> A in this embodiment holds the outer magnet 42, and the inner magnet 41 is fixed to the outer periphery of the support portion 51 a of the support plate 51. The magnet holder 53A is axially movable with respect to the support 51 and is prevented from rotating.

  The magnet holder 53A is integrally formed with a protruding portion that protrudes in the opposite direction to the spool side on the radially inner side, and a male screw portion 53B is formed there. On the other hand, the support plate 51 is provided with a first knob 60A that is rotatable and held off. A female screw portion 60B that is screwed into the male screw portion 53B is formed on the inner protruding portion of the first knob 60A.

  With the configuration described above, by rotating the first knob 60A, the magnet holder 53A can advance and retract in the axial direction due to the screwed relationship between the male screw portion 53B and the female screw portion 60B. That is, by rotating the first knob 60A, for example, as shown in FIG. 7, the magnet holder 53A can be moved to the spool side, and only the outer magnet 42 can be moved in the axial direction. .

  As described above, in the configuration in which the inner magnet 41 and the outer magnet 42 are disposed at a predetermined interval with respect to the conductor 30 as the magnetic braking device, only one of the magnets can be moved in the axial direction. With this, it becomes possible to adjust the braking force suitable for the required braking performance and the performance of the magnet. Of course, in this embodiment, the outer magnet 42 may be fixed and only the inner magnet 41 may be movable in the axial direction.

  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, an axial movement holding mechanism that holds a magnet so as to be movable in the axial direction may move the inner magnet 41 and the outer magnet 42 independently in the axial direction. As described above, since the inner magnet 41 and the outer magnet 42 can move independently in the axial direction, a wider range of braking characteristics can be set.

  In the above-described embodiment, the outer magnet 42 is configured to be movable and rotatable in the axial direction. However, any one of the magnets may be rotated independently. Further, in the above-described embodiment, the annular magnet is disposed opposite to the conductor 30 on the inner side and the outer side, but only one of them is provided with a magnet that moves in the axial direction. On the other hand, a magnetic material may be arranged opposite to the other. Furthermore, in the above-described embodiment, the movement and rotation in the axial direction of the magnet are configured to be adjusted steplessly, but may be configured to be adjustable stepwise.
