Description

  The present invention relates to a fishing reel, and more particularly to a fishing reel provided with a magnetic braking device that prevents over-rotation of a spool during a fishing line releasing operation.

  In general, a fishing system is provided with a magnetic braking device in which a cylindrical or ring-shaped conductor that rotates integrally with the spool is disposed opposite to a magnet on one side of a spool that is rotatably supported between side plates of a reel body. Reel is known. Such a fishing reel magnetic braking device is disposed between a side portion of one end in the axial direction of the spool and the outer plate of the reel body, and when the spool rotates at a high speed, Depending on the magnitude of the eddy current generated in the rotating conductor, a force in the direction opposite to the rotation direction of the spool acts on the spool as a braking force.

  As a fishing reel equipped with such a magnetic braking device, a tapered surface is formed inside the fishing line winding body of the spool, and a radially moving member that moves in the radial direction by the action of centrifugal force due to the spool rotation is a spool shaft. It is mounted so as to be movable in the axial direction as well, and the radial movement of the radial movement member due to centrifugal force when the spool rotates is converted into axial movement via the tapered surface inside the fishing line winding body, Along with a support member that supports a radial direction moving member, there is a device that moves a conductor provided on the support member back and forth within a magnetic field of a magnetic braking device and automatically adjusts a braking force according to an increase or decrease of a spool rotation speed (for example, a patent) Reference 1).

Also, a conductor is provided on the outer spool shaft on one side of the spool flange so as to be movable in the axial direction, and a taper surface is formed at the spool-side facing portion of this conductor to move in the radial direction when the spool rotates. There is one in which a direction moving member is engaged with the tapered surface and the radial movement of the radial moving member is converted into an axial movement of a conductor (for example, see Patent Document 2).
Japanese Patent Laid-Open No. 10-262518 JP-A-10-309158, FIG.

However, like the fishing reel shown in each embodiment of Patent Document 1, a configuration in which the moving direction of the radial moving member is moved in the axial direction by a tapered surface formed inside the fishing line winding body of the spool. In this case, in order to increase the spool capacity by changing the radial dimension of the spool, the outer diameter of the spool must be increased, and the spool becomes larger. Thereby, the whole fishing reel is also enlarged.
Further, as in Patent Document 2, when the movement of the radial movement member is converted into the axial movement of the conductor by the tapered surface formed on the spool-side facing portion of the conductor, the spool shape is a deep groove shape and the bobbin winding Although the capacity can be increased, the axial arrangement size of the conductor that is provided on the spool shaft on one side of the spool flange and has a tapered surface on the spool side facing portion is increased, and the axial direction of the reel unit is large. Turn into. As a result, the entire fishing reel is also enlarged.
In other words, all of the conventional fishing reels use the conversion part formed by one inclined surface formed in one member to change the radial movement of the radial movement member into the axial movement of the conductor. Due to the structure to be converted, a required axial space of the conversion part is necessary, and further, when the spool form is accommodated in the spool body of the spool to increase the spool volume, the entire spool becomes large, etc. There is a problem that the fishing reel cannot be made compact and compact while securing the spool capacity.
The present invention has been made based on such circumstances, and an object thereof is to secure a bobbin winding amount while reducing the size and size of a fishing reel equipped with a magnetic braking device.

The fishing reel of the present invention that achieves the above object has a conductor supported on one side of a spool rotatably supported by a reel body so that the conductor can be displaced, and the conductor is reeled in accordance with the rotational speed of the spool. In a fishing reel provided with a magnetic braking device that moves back and forth in a magnetic field of a magnet provided on a main body and increases or decreases a magnetic braking force acting on the spool, the magnetic braking device is fixed to a spool shaft including the spool. A support pin that extends in the radial direction of the spool shaft, and a movable member that is attached to the support pin through a long hole formed long in the axial direction of the spool shaft and is movable in the radial direction by rotation of the spool. A conductor-side engagement portion and a spool-side engagement portion that engage with the movable member on the conductor side and the spool side, respectively, and the spool-side engagement portion and the spool-side engagement portion are engageable with each other. One of the members, and, on one of the movable member engaged with to the conductive member side engagement portions, the converting means for converting the radial movement of the movable member in the axial movement of the conductor were formed It is characterized by.

According to the present invention, when the movable member moves in the radial direction by the rotation of the spool, the respective conversion means disposed on both sides of the movable member, that is, both the spool side and the conductor side, cause the movement of the movable member in the radial direction. In order to convert the conductor into axial movement, the conductor is moved directly in the axial direction by the conductor-side conversion means by the radial movement of the movable member, and also indirectly by the spool-side conversion means via the movable member. Moved axially. With these two conversion means, the conductor can be moved back and forth in the magnetic field of the magnet provided on the reel body by a slight radial movement of the movable member, and the entire reel can be reduced in size and size.
Further, the engaging portion of the spool side conversion means can be provided on the axially outer side of the spool body of the spool, and a deep groove spool having a large spool capacity is formed while preventing the entire reel from being enlarged. Is possible.

1 to 7 show a fishing reel 10 according to a preferred embodiment of the present invention.
As shown in FIG. 1, the fishing reel 10 of this embodiment is formed as a double-bearing type manual winding reel, and a pair of outer plates 14 a and 14 b of the reel body 12 is wound with a bobbin in this embodiment. Both end portions of a spool shaft 18 having a large-capacity deep groove-shaped spool 16 are rotatably supported via ball bearings 15a and 15b as shown, for example. On the right end side of the spool shaft 18, a pinion 22 that is rotationally driven by the handle 20 via a drive gear (not shown) is arranged coaxially with the spool shaft 18.

  The pinion 22 is interlocked with a clutch lever 24 disposed between the outer plates 14a and 14b via a known transmission mechanism (not shown). By pressing the clutch lever 24 downward, the pinion 22 is moved along the axial direction. Can move. For example, when the clutch lever 24 is pushed down from the position where the pinion 22 is fitted to the right end portion of the spool shaft 18 shown in FIG. 1, that is, the winding state, the pinion 22 is moved by an appropriate transmission mechanism disposed in the right outer plate 14b. Move to the right. As a result, the pinion 22 can be separated from the right end of the spool shaft 18 (spool free state). Further, when the handle 20 is rotated in a state where the pinion 22 is separated, the pinion 22 is fitted to the right end portion of the spool shaft 18 via a known return mechanism (not shown) to return to the original state (winding state). The spool 16 that is integrated with the spool shaft 18 and the pinion 22 rotate integrally. Reference numeral 26 designates a handle 20 for winding a fishing line (not shown) evenly on a cylindrical fishing line winding body 16b located between a pair of flanges 16a, 16a formed on both sides of the spool 16. A known fishing line guide device that reciprocates between a pair of outer plates 14a, 14b in conjunction with fishing line winding rotation is shown.

On one side located on the opposite side of the handle 20, a magnetic braking device 28 for preventing the spool 16 from over-rotating is disposed. The magnetic braking device 28 includes an inner ring magnet 30 in which a plurality of pairs of magnetized N poles and S poles that orient the magnetic field in the radial direction are alternately reversed in the circumferential direction, and the inner ring magnet 30. And an outer ring magnet 32 magnetized in the reverse direction. The inner ring magnet 30 and the outer ring magnet 32 are attached to the left outer plate 14a via a ring-shaped inner holding plate 34 and an outer holding plate 36, respectively, and apply a magnetic field to the annular gap 38 disposed therebetween. Form. Such magnets can be formed of rare earth magnets (neodymium, samarium, cerium), ferrite magnets, etc., and are neodymium magnets based on magnetic properties such as maximum energy product, coercive force, and residual magnetic flux density. Most preferred.
The outer ring magnet 32 is configured to rotate by rotating the knob A mounted on the left side plate 14a so that the magnetism acting on the conductor 40 described below can be adjusted. On the other hand, the inner ring magnet 30 may be moved.

  The electric conductor 40 of the magnetic braking device 28 is formed in a cylindrical shape that rotates integrally with the spool 16 and advances and retreats in the magnetic field formed in the annular gap 38 according to the rotational speed of the spool. The cylindrical conductor 40 is made of a nonmagnetic conductive material such as aluminum or copper. In particular, as shown in detail in FIG. 2, the conductor 40 of the present embodiment includes a boss portion 42 that is axially movable and non-rotatably mounted on the spool shaft 18, and a left outer plate of the boss portion 42. 14a is attached to a conductor support portion 46 having a disk-like portion 44 extending radially outward from the vicinity of the end portion close to 14a. The outer peripheral edge of the disk-like portion 44 is opposite to the handle 20, that is, the left outer side. It protrudes in the direction of the plate 14a and is fixed. The conductor support portion 46 can be formed of an appropriate resin or metal material as long as it has a strength capable of transmitting the braking force acting on the conductor 40 to the spool shaft 18. A resin material is preferable in terms of weight reduction.

As shown in detail in FIGS. 2 to 7, in order to allow the conductor 40 to move in the axial direction while making the conductor 40 unrotatable with respect to the spool shaft 18, the boss portion 42 of the conductor support portion 46 is provided with a handle, respectively. A pair of long holes 48 extending from the opening end on the 20 side to the intermediate portion are formed to face each other in the radial direction, and a support pin 50 penetrating the spool shaft 18 in the radial direction and being fixed is inserted into the long hole 48. . Further, the boss portion 42 forms a concave portion 42a having a shallow bottom portion 42b in the inner peripheral portion of the end portion facing the left outer plate 14a side, and the pressing spring 52 wound around the outer periphery of the spool shaft 18 It arrange | positions between the holding ring 19a latched by the groove | channel 18a, and the bottom part 42b of the recessed part 42a, and is urging | biasing the conductor support part 46, ie, the conductor 40, toward the spool 16 side. In order to stably support the conductor 40 against the urging force of the pressing spring 52, the regulating member 19b is fitted and locked to the circumferential groove 18b spaced inward by a predetermined distance from the circumferential groove 18a to the spool 16 side. is there. When the end of the boss portion 42 abuts against the restricting member 19b, the conductor support portion 46, that is, the conductor 40 is reliably prevented from moving in the spool 16 direction, and the conductor 40 and the inner and outer ring magnets 30, The positional relationship of 32 is reliably maintained. In addition, by setting the axial length of the long hole 48 of the boss portion 42 to a predetermined value, the support pin 50 is brought into contact with the closed end of the long hole 48 so that the shafts of the conductor support portion 46 and the conductor 40 can be contacted. It is also possible to restrict the direction movement.

A movable member 54 that can move on the support pin 50 in the radial direction of the spool shaft 18 is mounted on both ends of the support pin 50 protruding from the boss portion 42 so as to be movable in the axial direction. That is, as shown in FIGS. 2 and 4, the movable member 54 of the present embodiment is made of a soft or hard synthetic resin material and has a rectangular shape with chamfered upper corners along the long side in the axial direction of the spool 16. A long hole 56 that is long in the direction of the long side is formed through the center of the long side. As shown particularly in FIGS. 3 and 4, the long hole 56 has a width slightly larger than the outer diameter of the support pin 50 and is formed long in the direction of the spool shaft 18. Therefore, the movable member 54 can move relative to the support pin 50 along the longitudinal direction of the long hole 56, that is, the axial direction of the spool 16. A pair of guide walls 58 (see FIG. 4) is used to guide the movement in the radial direction of the spool so as not to rotate the movable member 54, and the movable member between the boss portion 42 of the conductor support portion 46 and the disk-shaped portion 44. The movable member 54 is slidably guided in the radial direction by projecting from a portion where the 54 abuts.
Note that the guide wall 58 may be omitted by forming the support pin 50 in a non-circular shape and engaging it with the oblong hole 56 so as to move and guide in the axial direction and the radial direction.

  Further, with the movable member 54 interposed therebetween, a conductor-side engagement portion 60 is disposed on the conductor support portion 46, and a spool-side engagement portion 62 is disposed on the spool 16 facing this, and the movable member 54 is disposed. When the spool rotates, it moves radially outward and engages both of these engaging portions, whereby the radial movement of the movable member 54 is converted into the axial movement of the conductor 40.

  In the present embodiment, the conductor-side engagement portion 60 and the spool-side engagement portion 62 are annular tapered surfaces (the conductor-side engagement portion 60 and the spool-side, respectively) that sequentially expand outward from the spool shaft 18 in the radial direction. The taper surfaces of the engagement portions 62 are formed so as to face each other in the axial direction, and the taper surfaces are opposed to each other and are inclined in opposite directions with the movable member 54 interposed therebetween. The surface acts as conversion means for converting the radial movement of the movable member 54 into the axial movement of the conductor 40. In the present embodiment, the radially outer corners of the movable member 54 are also formed as inclined surfaces corresponding to the opposing tapered surfaces, but the conductor-side engagement portion 60 and the spool-side engagement portion 62 As long as it can move smoothly along each tapered surface, it is not necessary to form such an inclined surface, and a small chamfered shape, an R shape, or a curved surface may be used.

As shown in FIG. 2, when the spool 16 is not rotating, the conductor support portion 46 is pressed toward the spool 16 by the urging force of the pressing spring 52, so that the conductive means that is a conversion means formed by a tapered surface is used. The body side engaging portion 60 is pressed to the spool 16 side and is locked to the spool side engaging portion 62 by a converting means formed by a tapered surface via the movable member 54. The conductor 40 is located outside the gap 38 (on the spool 16 side), and is thus maintained in a non-braking state that is hardly affected by the magnetic fields of the inner ring magnet 30 and the outer ring magnet 32. At this time, when the support pin 50 abuts on the end portions of the long hole 48 of the boss portion 42 and the long hole 56 of the movable member 54, and the regulating member 19 b engages with the respective end portions of the boss portion 42 and the movable member 54. In this case, the conductor support 46 and the movable member 54 are securely held, and rattling is prevented.

FIG. 7 shows a magnetic braking state when the spool 16 rotates at a high speed.
The movable member 54 moves radially outward along the support pin 50 by centrifugal force. The taper surface as the converting means for forming the conductor-side engaging portion 60 converts the radial movement of the movable member 54 into the axial movement of the conductor 40, whereby the conductor support 46 and the conductor 40 are moved to the left. The conductor 40 moves to the outer plate 14 a side, and the conductor 40 moves into the gap 38. Further, the tapered surface as the converting means forming the spool side engaging portion 62 moves the movable member 54 that moves radially outward along the long hole 56 toward the left outer plate 14 a in the axial direction. This radial and axial movement of the movable member 54 indirectly moves and converts the conductor 40 in the axial direction via the movable member 54. Thereby, when the movable member 54 moves in the radial direction, the amount of movement of the conductor 40 in the axial direction by the conversion means of the conductor-side engagement portion 60 and the amount of movement of the conductor 40 by the conversion means of the spool-side engagement portion 62 The conductor 40 is greatly moved in the axial direction by the amount of axial movement by both the conversion means.

  Therefore, in this embodiment, when the movable member 54 moves in the radial direction by the rotation of the spool 16, the conversion means disposed on both the spool 16 side and the conductor 40 side, which are both sides of the movable member 54, are used. A certain tapered surface converts the radial movement of the movable member 54 into the axial movement of the conductor 40. That is, the conductor 40 is directly converted and moved in the axial direction by the movable member 54 that contacts the tapered surface of the conductor-side engagement portion 60, and indirectly through the movable member 54 by the tapered surface of the spool-side engagement portion 62. In particular, the conductor 40 is moved in the axial direction, and the conductor 40 can be moved back and forth in the magnetic field of the inner ring magnet 30 and the outer ring magnet 32 by a slight radial movement of the movable member 54. Compactness is possible. In other words, when the movable member 54 moves in the radial direction by the same distance as the conventional fishing reel, it is possible to secure an axial stroke twice that of the conventional one.

FIG. 8 shows a first modification.
The various modifications or embodiments described below are basically the same as those in the above-described embodiment, and thus the same reference numerals are given to the same parts and the detailed description is omitted.

  In this modification, the spool side engaging portion 62 is provided as a separate member from the spool 16. That is, the spool-side engaging portion 62 of this modification is provided on a frustoconical receiving member 64 fixed to the spool shaft 18 on the outer side in the axial direction of the bobbin trunk 16b of the spool 16. On the left outer plate 14a side, an annular tapered surface that expands from the spool shaft 18 radially outward forms a converting means. The receiving member 64 also functions as a regulating member that supports the conductor support portion 46 against the urging force of the pressing spring 52.

  According to this modification, the spool-side engaging portion 62 that supports the movable member 54 is formed by a separate member positioned outside the spool 16, so that the spool body of the spool 16 is formed into a deep groove shape and its internal space is reduced. Even when the reel cannot be used, it can be formed on a spool having a large spool capacity while preventing the entire reel from becoming large.

  FIG. 9 shows a second modification. Here, the conductor side engaging portion 60 and the spool side engaging portion 62 are formed by short cylindrical protrusions that protrude from the conductor supporting portion 46 and the spool 16 to the movable member 54 side, respectively. On the other hand, the movable member 54 is formed with tapered surfaces 70 and 72 facing the protruding conductor engaging portion 60 and the spool side engaging portion 62 on both sides. As in the above embodiment, conversion means for converting the radial movement of the movable member 54 into the axial movement of the conductor 40 is formed.

10 shows that the converting means, that is, the tapered surface is formed on the conductor-side engaging portion 60, and the spool-side engaging portion 62 is formed by a cylindrical protrusion, and the converting means on the spool 16 side is used as the tapered surface 72 of the movable member 54. The modification formed by is shown.
FIG. 11 shows a modification in which the conductor-side engaging portion 60 is formed by a short cylindrical protrusion and the converting means on the conductor 40 side is formed by the tapered surface 70 of the movable member 54, contrary to FIG. 10. In this modification, the conversion means on the spool 16 side is formed by a tapered surface of the spool side engaging portion 62 formed on the inner side of the spool body of the spool 16 as in the embodiment shown in FIGS. is there.

  FIG. 12 shows a modification suitable for the shallow groove-shaped spool 16 having a relatively small pincushion capacity. In this modification, a spool-side engagement portion 62 is formed at the end of a short cylindrical protrusion 17 protruding in the axial direction from the radially inner side of a cylindrical bobbin trunk 16b around which a fishing line is wound. . The spool-side engaging portion 62 is formed with a tapered surface that is reduced in diameter toward the right outer side plate 14b as conversion means. In this case, it is possible to arrange both the conductor 40 side and spool side conversion means on the radially inner side of the winding drum portion of the spool 16.

  As described above, in any case, the movable member 54 is half of the conventional one when the inclination angle of the tapered surface is the same as the conventional one by the conversion means that is the tapered surface arranged on both sides of the movable member 54. When the same axial stroke as in the prior art is secured with the same amount of radial movement, and the same radial travel as in the prior art, it is possible to secure an axial stroke twice that of the prior art. Thereby, the internal space formed by these tapered surfaces, that is, the space for securing the movement of the movable member 54 is extremely smaller than that of the conventional one, and the moving distance of the movable member 54 can be reduced. The internal space can be effectively utilized as a minimum.

In addition, this invention is not restricted to the above-mentioned embodiment or various modifications, It is possible to combine these embodiment and modifications variously. For example, one or both of the conductor-side engaging portion 60 and the spool-side engaging portion 62 shown in FIG. 12 can be formed with short protrusions as shown in FIGS.
