Description

  The present invention relates to a fishing reel provided with a reel body that houses a drive unit such as a take-up drive mechanism or a reverse rotation prevention mechanism that is driven by a rotating operation of a handle.

  Usually, a fishing reel is configured to wind a fishing line around a spool via a power transmission mechanism by rotating a handle. For example, in a spinning reel as a fishing reel, a rotor having a fishing line guide portion is rotated via a drive shaft by rotating a handle, and the fishing line is wound around a spool. Further, such a fishing reel is equipped with a reverse rotation prevention device so that the rotor does not reverse due to the feeding of the fishing line wound around the spool during actual fishing.

  By the way, a fishing reel is used in a severe environment where seawater, sand, foreign matters, etc. are easily attached and invaded. Therefore, waterproof measures are taken for each part of the reel. For example, in the spinning reel disclosed in Patent Document 1, a waterproof structure is provided by a seal member to a reverse rotation prevention mechanism provided between the cylindrical shaft portion and the drive shaft formed in the front portion of the reel body, and water enters the inside. I try not to.

Japanese Patent No. 3981219

  The waterproof structure disclosed in Patent Literature 1 covers an opening of the cylindrical portion as a housing portion formed at the front portion of the reel body with a cover member, and is an elastic member covered on the outer periphery of the cover member The lip portion of the inner peripheral edge portion is brought into frictional contact with the outer periphery of the drive shaft disposed in the cylindrical portion, thereby preventing water from entering the inside.

  However, in the waterproof structure, it is difficult to obtain a high degree of concentricity between the tip of the lip portion of the cover member provided in the cylindrical portion and the drive shaft due to the influence of variations in component dimensions and the like. The frictional contact pressure between the lip portion and the drive shaft is not constant, and the waterproof performance is not stable. Moreover, the tip of the lip portion is easily worn with the progress of use, and in this case, the waterproof performance is lowered.

  Moreover, the subject that the rotational performance of a rotating component falls (rotation becomes heavy) by the influence of the friction contact pressure variation etc. remains.

  The present invention has been made paying attention to the above circumstances, and the object of the present invention is to reliably prevent water from entering a drive unit provided in a storage unit formed on a reel body, and water or the like can enter. An object of the present invention is to provide a fishing reel that can always obtain a stable driving performance even in a harsh environment.

In order to solve the above-described problems, the present invention provides a fishing reel in which a fishing line is wound around a spool supported by a reel body by a rotation operation of a handle coupled to a take-up drive mechanism built in the reel body. A pinion that is formed in a concave shape on the reel body, and that partially accommodates and supports a pinion that rotates in conjunction with the operation of the handle, and that includes a receiving recess that is provided with an anti-reverse mechanism inside, an opening of the receiving recess, and the pinion And a magnetic seal mechanism for sealing the opening by forming a magnetic circuit therebetween and holding a magnetic fluid therebetween.

According to the above configuration, since the opening of the housing recess is effectively and reliably sealed by the magnetic seal mechanism that holds the magnetic fluid by the magnetic circuit, water can be reliably prevented from entering the housing recess, Various drive elements (for example, gears ) including the pinion to be accommodated and the reverse rotation prevention mechanism can be protected from seawater, sand, foreign matters, and the like. Therefore, a stable driving performance (for example, a reverse rotation prevention function, a winding driving performance, etc.) can always be obtained even in a harsh environment where water or the like easily enters.

In the above configuration, the magnetic seal mechanism includes a magnet, a cylindrical magnetic body that is fitted to the pinion and forms a magnetic circuit with the magnet, and the magnet and the magnetic body. You may comprise by the magnetic fluid hold | maintained. According to this, since the magnetic seal is constituted by fitting the cylindrical magnetic body with respect to the pinion, there is no need to form in an easy magnetic material corrode example pinion, whereby the pinion of corrosion (Thus, there is no need to subject the pinion to corrosion treatment or the like), and the material for forming the pinion is not restricted, so that an optimal material can be selected. In addition, the cylindrical magnetic body to be fitted allows the concentricity in the seal region (the concentricity between the pinion and the magnetic seal) to be obtained with high accuracy, and therefore, a reliable sealing state can always be realized, Excellent stability of waterproof performance. In addition, the cylindrical magnetic body which comprises a magnetic seal mechanism does not need to be directly fitted in the pinion of a fishing reel. For example, a configuration in which a cylindrical magnetic body is fitted to a non-magnetic color member or the like attached to the pinion may be used. The cylindrical magnetic body may be made of a magnetic material that is deposited on the outer peripheral surface of the nonmagnetic collar member by, for example, plating or vapor deposition (physical vapor deposition, chemical vapor deposition, or the like).

In the above configuration, the cylindrical magnetic body may be non-rotatably fitted to the non-magnetic pinion, and the magnet is supported by a cover member that covers the opening of the housing recess. May be.

  According to the present invention, it is possible to reliably prevent water from entering the drive unit provided in the housing unit formed in the reel body, and to always obtain stable drive performance even in a harsh environment where water or the like easily enters. A fishing reel can be provided.

  Hereinafter, embodiments of a fishing reel according to the present invention will be specifically described with reference to the accompanying drawings.

  1 to 3 show a spinning reel as a fishing reel according to a first embodiment of the present invention. As shown in FIG. 1, a reel leg 1 of a spinning reel according to the present embodiment is integrally formed with a reel leg 2 attached to a fishing rod, and a rotor 3 rotatably supported in front of the reel leg 2 A spool 4 supported so as to be movable back and forth in synchronism with the rotational movement of the rotor 3 is disposed.

  The rotor 3 includes a pair of arm portions 3a that rotate around the spool 4, and a bail support member 3c having a base end portion of the bail 3b attached to the front end portion of each arm portion 3a is used for winding a fishing line. It is rotatably supported between the position and the fishing line discharge position. Note that one base end portion of the bail 3b is attached to a fishing line guide portion 3d provided integrally with the bail support member 3c.

  A handle shaft 5 is rotatably supported in the reel body 1, and a handle 6 is attached to the protruding end portion. The handle shaft 5 is engaged with a take-up drive mechanism. The take-up drive mechanism meshes with the drive gear 7 and a drive gear 7 mounted on the handle shaft 5 so as to be integrally rotatable. A pinion 8 extending in a direction orthogonal to the handle shaft 5 and having a hollow portion extending in the axial direction therein is provided.

  The pinion 8 is rotatably supported in the reel body 1 via a bearing 9 and extends toward the spool 4 side, and the rotor 3 is attached to the tip portion. The bearing 9 is held by a bearing set screw 30 that is screwed into the reel body 1.

  Further, the pinion 8 is provided with a rolling one-way clutch 10 at an intermediate portion thereof, and the one-way clutch 10 is operated by rotating a switching operation lever 11 provided outside the reel body 1. A known reverse rotation prevention mechanism (stopper) for preventing reverse rotation of the handle 6 (rotor 3) in the fishing line feeding direction is configured.

  A spool shaft 12 extending in a direction perpendicular to the handle shaft 5 and having the spool 4 mounted on the tip side is inserted into the hollow portion formed in the pinion 8 so as to be movable in the axial direction. The pinion 8 is engaged with a known spool reciprocating device 13 for reciprocating the spool 4 (spool shaft 12) back and forth.

  In the fishing spinning reel having such a configuration, when the winding operation is performed by the handle 6, the rotor 3 is driven to rotate through the winding drive mechanism, and the spool 4 is moved through the spool reciprocating device 13. Since it is reciprocated back and forth, the fishing line is wound evenly around the winding body 4a of the spool 4 via the fishing line guide 3d.

  As shown in FIG. 2, the rolling one-way clutch 10 includes an inner ring 21 that is non-rotatably fitted to the pinion 8, a cage 27 that is disposed outside the inner ring 21, and an outer side of the cage 27. And an outer ring 25 arranged on the outer side.

  On the inner peripheral surface of the outer ring 25, a free rotation region where the plurality of rolling members 28 held by the cage 27 can freely rotate and a wedge region which prevents the rotation of the plurality of rolling members are formed. Each rolling member is biased to the wedge region by a spring member provided in the cage 27. The outer ring 25 is prevented from rotating with respect to the reel body 1 by a detent plate 37 disposed concentrically on the radially outer side of the cage 27. Specifically, as clearly shown in FIG. 3, a locking projection 37 a protruding outward in the radial direction is provided on a part of the rotation stop plate 37 in the circumferential direction, and the locking projection 37 a. Is locked in the locking groove 39 of the reel body 1 through the notch 25a of the outer ring 25, so that the outer ring 25 is prevented from rotating relative to the reel body 1 by the locking projection 37a.

  In the one-way clutch 10 having such a configuration, when the inner ring 21 rotates forward together with the pinion 8 (the rotor 3 rotates in the fishing line winding direction), the rolling member 28 of the retainer 27 is positioned in the free rotation region of the outer ring 25. Therefore, the rotational force of the inner ring 21 is not transmitted to the outer ring 25 (not blocked by the outer ring 25), and thus the rotor 3 rotates together with the pinion 8 without any trouble. On the other hand, when the inner ring 21 tries to rotate in reverse with the pinion gear 13 (the rotor 8 rotates in the fishing line feeding direction), the rolling member of the retainer 27 is positioned in the wedge region of the outer ring 25, and thus the rotational force of the inner ring 21 is increased. Is transmitted to the outer ring 25, which serves as a stopper, and the rotation (reverse rotation) of the pinion 8 and the rotor 3 is prevented.

  The operation of the reverse rotation preventing mechanism with such a one-way clutch 10 can be controlled by the switching operation lever 11. Specifically, as shown in FIGS. 2 and 3, the switching operation lever 11 has a switching cam 33 that extends substantially parallel to the spool shaft 12 in the reel body 1, and the tip of the switching cam 33. The protrusion 33 a is engaged with the engagement hole 32 a of the operating arm 32. Further, the operating arm 32 is connected to the retainer 27 through the notch 25 b of the outer ring 25. Therefore, in this configuration, when the holder 27 is rotated via the switching cam 33 and the operating arm 32 by rotating the switching operation lever 11, the rolling member 28 held by the holder 27 is moved. A reversible position (a position where the rotor 3 can be rotated in reverse) where the outer ring 25 is forcibly held in the free rotation region of the outer ring 25 against the biasing force of the spring member, and the outer ring 25 by the biasing force of the spring member. It is possible to selectively switch between a reverse rotation prevention position (a position where the reverse rotation of the rotor 3 is prevented) to be positioned in the wedge region.

Next, the magnetic seal mechanism disposed in the spinning reel having the above configuration will be described.
As shown in FIG. 2, the reel body 1 partially accommodates a pinion 8 (and / or an inner ring 21 that rotates integrally with the pinion 8) as a driving member that rotates in conjunction with the operation of the handle 6. The housing recess 40 supported by the groove 9 is formed in a concave shape. The accommodation recess 40 accommodates and holds the one-way clutch 10 of the above-described reverse rotation prevention mechanism in a positioned state (a reverse rotation prevention mechanism is provided in the accommodation recess 40), and on the front side facing the spool 4 side. An opening 40a is provided. Since there is a possibility that moisture, foreign matter or the like may enter the opening 40a through a route indicated by an arrow in the drawing, the opening 40a is partially closed by the cover member 42 and partially left by the cover member 42. In the opening 42a, a magnetic circuit is formed between the opening 42a and the outer peripheral surface of the pinion 8 made of a nonmagnetic material (for example, a copper alloy, an aluminum alloy, etc.), and a magnetic fluid is held therebetween. Thus, a magnetic seal mechanism 50 for sealing the opening 42a is provided. The outer peripheral end of the cover member 42 is attached to the reel body 1 by a set screw 60, and a seal member 62 is interposed between the inner surface of the outer peripheral end of the cover member 42 and the mounting end surface of the reel main body 1. It is inserted.

  The magnetic seal mechanism 50 for sealing the inside of the housing recess 40 for housing the driving elements such as the one-way clutch 10 and the pinion 8 includes a magnet 51 disposed so as to surround the pinion 8 with a predetermined gap. A magnetic circuit is formed between the holding member (magnetic ring) 52 to be held and the magnet 51 by being fitted (externally fitted) to the pinion 8 (thus having at least an axial length facing the holding member 52). The cylindrical magnetic body 53 and the magnetic fluid 55 held between the magnet 51 and the cylindrical magnetic body 53 are configured as one unit (that is, if the cover member 42 is removed from the reel body 1, The magnetic seal mechanism 50 (the magnet 51, the holding member 52, the magnetic body 53, and the magnetic fluid 55) is also removed together with the cover member 42).

  In this case, the magnet 51 is formed in a ring shape having a predetermined thickness so that the pinion 8 can be inserted, and the holding member 52 sandwiches the magnet 51 thus formed from both sides. Configured to hold.

  The holding member 52 is formed so as to sandwich and hold the ring-shaped magnet 51, and a recess 51 </ b> A is formed along the circumferential direction inside thereof, and is supported by the cover member 42 together with the magnet 51. Specifically, the holding member 52 is sandwiched and held between the cover member 42 that is in contact with one side and the support plate 63 that is in contact with the other side and is attached to the inner surface of the cover member 42. A seal member 69 is interposed between the cover member 42 and the holding member 52. The holding member 52 is configured such that a slight gap G is generated between the holding member 52 and the outer surface of the cylindrical magnetic body 53.

  The cylindrical magnetic body 53 is formed of an iron-based material, for example, steel, SUS430, SUS440C, SUS630, and the like. Accordingly, the magnet 51 holds the holding member 52 and the cylindrical magnetic body 53. A magnetic circuit is formed between the two. Note that the length of the cylindrical magnetic body 53 may be long enough to generate the magnetic circuit (a length that can stably hold the magnetic fluid 55). The holding member 52 is formed to be slightly longer than the axial length so as to be covered. The magnetic body 53 is positioned by having one end applied to the end surface of the inner ring 21 of the one-way clutch 10 and the other end applied to the end surface of the rotor 3. In this case, it is preferable that the magnetic body 53 is non-rotatably fitted to the nonmagnetic pinion 8. That is, when the cylindrical magnetic body 53 is non-rotatably fitted (circularly fitted and supported) so as to rotate integrally with the pinion 8, moisture or the like is generated between the inner periphery of the magnetic body 53 and the outer periphery of the pinion 8. Invasion can be effectively suppressed.

The magnetic fluid 55 is configured by dispersing magnetic fine particles such as Fe ₃ O ₄ in a surfactant and base oil, and has a characteristic of reacting when the magnet is brought close to the magnet. For this reason, as shown in FIG. 2, the magnetic fluid 55 is contained in the recess 51 </ b> A and the magnetic circuit formed by a magnet 51, a holding member 52 that holds the magnet 51, and a cylindrical magnetic body 53. It is stably held in the gap G and seals the opening 42a.

  As described above, according to the present embodiment, the opening 42a of the housing recess 40 is effectively and reliably sealed by the magnetic seal mechanism 50 that holds the magnetic fluid 55 by the magnetic circuit. Infiltration can be reliably prevented, and various drive elements (for example, the one-way clutch 10 of the reverse rotation prevention mechanism) including the pinion 8 housed in the housing recess 40 can be protected from seawater, sand, foreign matter, and the like. Therefore, a stable driving performance (for example, a reverse rotation prevention function, a winding driving performance, etc.) can always be obtained even in a harsh environment where water or the like easily enters.

  In the above configuration, the magnetic seal mechanism 50 includes a magnet 51, a cylindrical magnetic body 53 that is fitted to the pinion 8 and forms a magnetic circuit with the magnetic 51 stone, and the magnet 51 and the magnetic body 53. And a magnetic fluid 55 held between the two. Thus, if the magnetic seal is configured by fitting the cylindrical magnetic body 53 to the pinion 8, for example, the pinion 8 does not need to be formed of a magnetic material that easily corrodes. Therefore, it is possible to select an optimum material because the material for forming the pinion 8 is not restricted. . In addition, the cylindrical magnetic body 53 to be fitted allows the concentricity in the seal area (the concentricity between the pinion 8 and the magnetic seal) to be obtained with high accuracy, and therefore a reliable sealing state is always realized. Yes, it has excellent waterproof performance.

  FIG. 4 shows a second embodiment of the present invention. As illustrated, in this embodiment, the inner ring 21 of the one-way clutch 10 and the magnetic body 53 of the magnetic seal mechanism 50 are integrally formed. Other configurations are the same as those of the first embodiment described above. Therefore, it is possible to obtain the same operational effects as those of the first embodiment and to reduce the number of parts, which is beneficial.

  FIG. 5 shows a third embodiment of the present invention. As illustrated, in this embodiment, the holding member 52 that holds the magnet 51 also serves as the cover member 42. That is, the holding member 52 and the magnet 51 serve as the cover member 42. Other configurations are the same as those of the first embodiment described above. Therefore, it is possible to obtain the same operational effects as those of the first embodiment and to reduce the number of parts, which is beneficial.

  FIG. 6 shows a fourth embodiment of the present invention. As shown in the figure, in the present embodiment, the magnet 51 constituting the magnetic circuit described above is directly supported by the cover member 42 instead of being held by the holding member. That is, the magnet 51 is sandwiched between the cover member 42 and the support plate 63, and the seal member 69 is inserted between the magnet 51 and the cover member 42. In this case, the magnet 51 is formed in a ring shape in advance, and a concave groove 51 a is formed on the inner peripheral surface so as to hold the magnetic fluid 55. That is, the concave groove 51a is formed along the circumferential direction so as to face the outer peripheral surface of the cylindrical magnetic body 53, and the magnetic fluid 55 is held in the concave groove 51a. According to such a configuration, the structure can be simplified and the number of parts can be reduced, which is beneficial.

  7 and 8 show a fifth embodiment of the present invention. In the above-described embodiment, the spinning reel is exemplified as the fishing reel. However, in the fifth embodiment, the present invention is applied to the dual-bearing type reel.

  As shown in the figure, the reel body 101 of the dual-bearing type reel includes left and right frames 102a and 102b, and left and right side plates 103a and 103b attached to the left and right frames 102a and 102b with a predetermined space. A spool shaft 105 is rotatably supported between the left and right frames 102a and 102b (left and right side plates 103a and 103b). A spool 106 around which a fishing line is wound is attached to the spool shaft 105.

  A handle shaft 109 on which a handle 108 is mounted is rotatably supported on the right side plate 103b side. A winding drive mechanism is coupled to the handle shaft 109, and the spool 106 is driven to rotate via the winding drive mechanism by rotating the handle 108. The handle shaft 109 is rotatable only in the fishing line winding direction by a one-way clutch 110 interposed between the handle plate 109 and the right side plate.

  The winding drive mechanism includes a drive gear 112 that is rotatably supported on the handle shaft 109 via a drag mechanism, and a pinion 113 that meshes with the drive gear 112. The pinion 113 is configured to be connected to and disconnected from the spool shaft 105 via a known clutch mechanism. When the clutch is in an ON state, the rotational driving force of the handle 108 is applied to the spool 106 via the drive gear 112 and the pinion 113. In the clutch OFF state, the driving force transmission state is canceled and the spool 106 is set in a free rotation state. The above-described clutch operation is performed by operating an operation lever (not shown) protruding from the reel body 101.

  A level wind mechanism 120 is provided in front of the spool 106 between the left and right plates 103a and 103b. The level wind mechanism 120 reciprocates left and right in front of the spool 106, and is supported between the fishing line guide body 121 having an insertion hole through which the fishing line is inserted and the left and right side plates 103a and 103b, and has an endless cam groove 123a on the outer periphery. The worm shaft 123 is formed.

  The worm shaft 123 is fixed between the left and right frames and is rotatably accommodated in a cylindrical member 125 in which a through hole is formed along the axial direction. The worm shaft 123 is accommodated in the fishing line guide body 121 through the through hole. The held engagement pin engages with the endless cam groove 123a to reciprocate the fishing line guide body 121 left and right. The fishing line guide body 121 is supported by a guide pillar (not shown) supported between the left and right frames so as to be prevented from rotating around the worm shaft 123 when reciprocating.

  A gear 130 that meshes with a gear 112 a that is connected to the drive gear 112 in the axial direction so as to rotate integrally with the drive gear 112 is provided at the end on the right side plate side of the worm shaft 123. The gear 130 is inputted with a rotational driving force by a winding operation of the handle 108 via the handle shaft 109, the driving gear 112 and the gear 112 a, and the rotational driving force is outputted to the worm shaft 123. .

  Further, in the present embodiment, the right side plate 103b of the reel body 101 has a concave recess 150 in which a handle shaft 109 as a drive member that rotates in conjunction with the operation of the handle 6 is partially received and supported by a bearing 149. Is formed. The accommodation recess 150 accommodates and holds the one-way clutch 110 of the above-described reverse rotation prevention mechanism in a positioned state (the reverse rotation prevention mechanism is provided in the accommodation recess 150), and an opening 150a is provided on the handle 108 side. Have. In the opening 150a, a magnetic circuit is formed between the opening 150a and the outer peripheral surface of the handle shaft 109 made of a nonmagnetic material (for example, a copper alloy, an aluminum alloy, etc.), and a magnetic fluid is supplied therebetween. A magnetic seal mechanism 200 that seals the opening 150a by holding is provided.

  In this configuration, an operating body 171 constituting a known drag mechanism 170 is screwed to the right end portion of the handle shaft 109. When the operating body 171 is rotated, the first pressing body 173, which is a collar member that is fitted to the handle shaft 109 so as to be movable in the axial direction and integrally rotatable, moves in the axial direction, via the disc spring 175. Then, the second pressing body 177 that also serves as the inner ring of the one-way clutch 110 is pressed, the friction member 178 is pressed with a desired pressing force, and a braking force is generated between the handle shaft 109 and the gear 112a.

  As described above, the right end portion of the handle shaft 109 can be rotated by the bearing 149 with respect to the reel body 101 (cylindrical support portion 190 forming the housing recess 150 formed in the right side plate 103b constituting the reel body 101). It is supported by. In this case, the bearing 149 is installed on the first pressing body 173 that is a collar member.

  The magnetic seal mechanism 200 that seals the bearing 149 and the one-way clutch 110 is installed on the handle 108 side with respect to the bearing 149, and holds the ring-shaped magnet 51 arranged so as to surround the handle shaft 109.

The magnetic body 53 includes a magnetic fluid (not shown) held between the ring-shaped magnet 51 and the cylindrical magnetic body 53. The cylindrical magnetic body 53 is fitted to the inner periphery of the inner ring of the bearing 149 and is restricted in the axial direction by a fastener, so that the first pressing body 173 does not move following the axial movement. It has become.

  The cylindrical magnetic body 53 only needs to have such a length that a magnetic circuit is generated between the magnet 51 and the holding member 52. In this embodiment, a flange 53d is formed at the base end, The bearing 149 is held so as not to come off.

  The ring-shaped magnet 51 of the magnetic seal mechanism 200 having the above-described configuration and the holding member 52 that holds the magnet are fitted (internally fitted) on the inner surface of the cylindrical support portion 190 adjacent to the bearing 149. One of the holding members 52 is retained by a non-magnetic washer 193 that is retained on the inner surface of the cylindrical support 190 via a retaining ring 192, and the other of the retaining members 52 is interposed with a non-magnetic washer 197. Is applied to the bearing 149.

  Also with such a magnetic seal mechanism 200, the inside of the housing recess 150 can be reliably sealed, and it is not necessary to form the handle shaft 109 with a magnetic material, and corrosion can be prevented.

  In the present embodiment, the first pressing body 173 may be made of a magnetic material. By comprising in this way, the cylindrical magnetic body 53 becomes unnecessary and it becomes possible to combine the function as a pressing body of a drag mechanism, and the function as a cylindrical magnetic body of a magnetic seal mechanism.

  Needless to say, the present invention is not limited to the above-described embodiments, and can be variously modified without departing from the scope of the invention. For example, the magnetic seal mechanism having the above-described configuration can be applied to an opening of an accommodation recess (a concave space that accommodates various drive units including a drive member) of various fishing reels. In addition, the installation position and the installation form are not particularly limited. Moreover, about the cylindrical magnetic body fitted by a drive member, it may be fitted externally or may be fitted internally. Furthermore, when configuring the magnetic seal mechanism, the configuration of the magnet that holds the magnetic fluid, the configuration that holds the magnet, the shape of the holding member, and the like can be modified as appropriate. Of course, the structure which attaches a magnet directly to a reel main body may be sufficient, without providing a holding member like the structure shown in FIG. Furthermore, the configurations shown in the drawings can be implemented in combination as appropriate.
