Description

  The present invention relates to a connecting member, in particular, a fishing reel connecting member that is used in a fishing reel and is connected to a non-circular portion formed on the outer periphery of a shaft member in a relatively non-rotatable manner.

  Fishing reels such as spinning reels and double-bearing reels are provided with a drag mechanism to prevent the fishing line from being cut by excessive tensile force acting on the fishing line. For example, in the case of a spinning reel, the conventional drag mechanism has a first drag washer that is connected to a spool shaft (an example of a shaft member) so as not to rotate relative to the spool shaft, and a second drag washer that is connected to the spool so as to rotate together. And brake the spool. In the case of a dual-bearing reel, it has a drag washer (an example of a connecting member) that is non-rotatably connected to a handle shaft (an example of a shaft member). Brakes the gear.

  In both the spinning reel and the dual-bearing reel, a pair of chamfered portions (an example of a non-circular portion) parallel to each other are formed on the outer peripheral surface of the shaft member so as to connect the drag washer in a non-rotatable manner. The drag washer is formed with a non-circular hole that engages with the non-circular portion at the center.

In this type of drag mechanism, the drag force of the drag mechanism may fluctuate when liquid enters the friction surface of the drag washer. In view of this, there has been conventionally known one in which a seal member is disposed on the outer peripheral portion of the pressing member of the drag knob that contacts the first drag washer (see, for example, Patent Document 1). A drag knob of a conventional drag mechanism has a non-circular hole that is non-rotatably engaged with a non-circular portion and is connected to the spool shaft so as not to be relatively rotatable, and a relative rotation with the press member. And an operation member that is freely connected and screwed onto the spool shaft. A seal member is disposed between the pressing member and the spool. This seal member can prevent liquid from entering the drag mechanism through the gap between the spool and the outer peripheral surface of the drag knob.

  In the conventional configuration, it is possible to prevent liquid from entering from a gap between the spool and the outer peripheral surface of the pressing member of the drag knob. However, it is difficult to prevent liquid from entering from the gap between the center portion of the pressing member and the spool shaft. That is, since the non-circular hole is formed in the pressing member, it is difficult to seal the gap between the non-circular hole and the outer peripheral surface of the spool shaft. In addition, if the seal member that engages with the non-circular portion is disposed between the non-circular hole and the non-circular portion, sealing can be performed. However, the seal member may be deformed when force is applied to the pressing member via the first drag washer as in the case of drag operation.

  An object of the present invention is to prevent a seal from being deformed when a force is applied to a connecting member of a fishing reel, so that a gap between the shaft member and the connecting member can be reliably sealed.

  A fishing reel connecting member according to a first aspect of the present invention is a member that is used in a fishing reel and is non-rotatably connected to a non-circular portion formed on an outer periphery of a shaft member, and includes a main body member and a seal member. I have. The main body member has a non-circular hole that is non-rotatably engaged with the non-circular portion. The seal member is a member made of an elastic body that is arranged in the axial direction in the non-circular hole and has a seal hole that can contact the non-circular hole and is provided in the main body member.

  In this connection member, the non-circular hole of the main body member engages with the non-circular portion of the shaft member, and the connection member is non-rotatably connected to the non-circular portion of the shaft member. Further, the seal hole of the seal member contacts the non-circular portion, and the gap between the non-circular portion and the non-circular hole is sealed. Here, since the non-circular hole that engages with the non-circular portion and the seal member that contacts and seals the non-circular portion are arranged side by side in the axial direction, the gap between the shaft member and the connecting member can be reliably sealed. At the same time, since the non-circular hole engages with the non-circular portion, the deformation of the seal member can be suppressed when a force is applied to the connecting member as in the drag operation.

  A connecting member for a fishing reel according to a second aspect is the member according to the first aspect, wherein the seal member is integrally formed with the main body member by insert molding. In this case, since the seal member is integrally formed with the main body member, the seal member is difficult to come off from the main body member.

  A fishing reel connecting member according to a third aspect of the present invention is the member according to the first or second aspect, wherein the noncircular portion has a pair of chamfered portions arranged in parallel to each other, and the noncircular hole is formed in the chamfered portion. It is a hole having a pair of engaging surfaces to be engaged. In this case, the non-circular portion can be formed with high accuracy by processing, and the non-circular hole can be formed with high accuracy by molding.

  A fishing reel connecting member according to a fourth aspect of the present invention is the member according to any one of the first to third aspects, wherein the main body member is disposed around a spool shaft of a spinning reel as a shaft member. In this case, in the connecting member of the spinning reel, it is possible to reliably prevent liquid from entering the drag mechanism through the gap between the spool shaft and the connecting member.

  A fishing reel connecting member according to a fifth aspect of the present invention is the member according to the fourth aspect, wherein the body member is a cylindrical spool support shaft as a shaft member that is non-rotatably and detachably connected to the spinning reel spool shaft. Installed. In this case, since the washer member is attached to the spool support shaft that is detachably attached to the spool shaft, the drag force is maintained by attaching and detaching the spool support shaft with the spool attached thereto. You can change the spool.

  A fishing reel connecting member according to a sixth aspect of the present invention is the member according to any one of the first to third aspects, wherein the main body member is disposed around the handle shaft of the dual-bearing reel. In this case, in the star drag mechanism of the dual-bearing reel, it is possible to reliably prevent liquid from entering from the gap between the handle shaft and the connecting member.

  The fishing reel connecting member according to a seventh aspect of the present invention is the member according to any one of the first to sixth aspects, wherein the seal hole protrudes so as to be able to contact the non-circular portion, and the tip is smaller and sharper than the non-circular hole. The lip portion is formed. In this case, when the lip with a sharp tip is brought into contact with the shaft member, the sliding resistance with the shaft member is reduced, the connecting member can be smoothly attached and detached, and when the connecting member is used as a drag knob, When the knob is turned in the slack direction, the drag force decreases smoothly.

  According to the present invention, since the non-circular hole that engages with the non-circular portion and the seal member that contacts and seals the non-circular portion are arranged side by side in the axial direction, the clearance between the shaft member and the connecting member is ensured. Since the non-circular hole engages with the non-circular portion, the deformation of the seal member can be suppressed when a force is applied to the connecting member as in the drag operation.

In addition, in FIG. 3, the cross section is drawn on the lower side of the front-rear axis X, and the side surface in a state where the upper side is slightly pressed is drawn.

  The push operation unit 66a is formed in a rounded button shape. The retaining collar 66b is engaged with the first inner peripheral portion 8h of the spool support shaft 8, and is retained by a C-type retaining ring 69 attached to the first inner peripheral portion 8h. A return spring 55 made of a coil spring is provided on the rear surface of the retaining collar portion 66b. The return spring 55 biases the push button 66 in the direction opposite to the pressing direction. Thus, when the push operation is stopped, the push button 66 returns to the initial position on the left side (front in the axial direction) in FIG. A protrusion 66e protruding in the radial direction is formed on the retaining collar 66b, and a slit 8j into which the protrusion 66e fits is formed at the front end of the spool support shaft 8 along the axial direction. . Thereby, the push button 66 is prevented from rotating. The cylindrical portion 66 c is disposed in the gap between the second inner peripheral portion 8 i and the spool shaft 15. The pressing portion 66d presses the second retaining member 68, and is a pair of inclined surfaces (FIG. 3) for deforming from the locking groove 15c of the spool shaft 15 beyond the outermost diameter portion of the tapered portion 15b. (Only one of them is shown) 66f.

When the center portion of the second retaining member 68 is locked to the locking groove 15c of the spool shaft 15, the notch 8g is formed closer to the spool shaft core than the outer peripheral surface of the locking groove 15c. It is arranged slightly curved. Due to the urging force generated by the bending deformation, the spool 4 is held on the spool shaft 15 in an unsteady manner.

<Operation of one-touch attachment / detachment mechanism>
When the push button 66 is pressed, the inclined surface 66f of the pressing portion 66d of the push button 66 comes into contact with the second retaining member 68, and the inclined surface 66f moves the first and second retaining members 67, 68 rightward in FIG. And the first and second retaining members 67 and 68 are deformed. When the second retaining member 68 is deformed to a position exceeding the outermost diameter portion of the tapered portion 15 b of the spool shaft 15, the spool 4 can be detached from the spool shaft 15.

  When the removed spool 4 is mounted from the tip of the spool shaft 15, the first and second retaining members 67 and 68 are pressed by the tapered portion 15 b of the spool shaft 15. And if it exceeds the taper part 15b, it will be latched by the latching groove 15c by elasticity of the 1st and 2nd retainer members 67 and 68, and the spool 4 will be connected non-rotatably with a spool axis | shaft.

<Configuration of drag mechanism>
As shown in FIG. 2, the drag mechanism 9 includes a drag adjusting unit 57 that adjusts the drag force, and a friction unit 58 that adjusts the frictional force by the drag adjusting unit 57. The drag adjusting portion 57 includes an operation member 60 that is screwed onto the spool support shaft 8 and a pressing member (an example of a connecting member according to the present invention) 61 that is pressed by the operation member 60 and presses the friction portion 58. . The operation member 60 includes a knob handle 60b having knob protrusions 60a that project radially in three directions, and an operation member 60 having a knob flange 60c fixed to the knob handle 60b. A nut 62 that engages with the male threaded portion 8e of the spool support shaft 8 is mounted on the knob flange 60c so as not to rotate but to move in the axial direction. Between the nut 62 and the pressing member 61, a coil spring 63 for smoothly adjusting the drag force is mounted in a compressed state.

  The pressing member 61 is attached to the spool support shaft 8 disposed around the spool shaft 15 so as not to be relatively rotatable and to be movable in the axial direction. The pressing member 61 is connected to the operation member 60 so as to be rotatable relative to the operating member 60 and not to be dropped off. As shown in FIG. 5, the pressing member 61 includes a cylindrical main body member 70 with a flange and an elastic seal member 71 integrally formed on the main body member 70 by, for example, insert molding.

  As shown in FIGS. 6 and 7, the main body member 70 is a member made of, for example, a synthetic resin, and includes a cylindrical portion 70a and a retaining portion 70b having a larger diameter than the cylindrical portion 70a. . The cylindrical portion 70a has a non-circular hole 70c in its inner peripheral portion that is non-rotatably engaged with the non-circular portion 8c. The non-circular hole 70c is an oval hole having a pair of engagement surfaces 70d that engage with the chamfered portion 8c1. A stepped portion 70e for mounting the retaining ring 64a shown in FIG. 2 is formed on the rear surface of the flange portion 70b. The retaining ring 64a is retained by a retaining spring 64b retained on the inner peripheral surface of the knob flange 60c. As a result, the pressing member 61 to which the retaining ring 64a is attached is retained on the knob flange 60c so as to be relatively rotatable. In the body member 70, a plurality of inflow holes 70f for pouring an elastic molding material to be a seal member when the seal member 71 is insert-molded are arranged at intervals in the circumferential direction. In addition, a spring cylindrical storage space 70g in which the coil spring 63 is stored and abutted is formed in the front portion of the inner peripheral portion. As shown in FIG. 2, the tip of a seal ring 72 that seals the gap between the inner peripheral surface of the bobbin trunk 7 a and the outer peripheral surface of the pressing member 61 is in contact with the outer peripheral surface of the cylindrical portion 70 a of the main body member 70. Yes. The seal ring 72 is provided to prevent the liquid from entering the drag mechanism 9. The tip of the seal ring 72 is formed in a sharp lip shape. Thereby, even if the spool 4 rotates during the drag operation, the rotational resistance can be reduced.

  As shown in FIG. 5, the seal member 71 is an elastic member made of synthetic resin such as nitrile rubber, for example. The seal member 71 has a seal hole 71a that is arranged in the axial direction in the non-circular hole 70c and can contact the non-circular portion 8c. The seal hole 71a has an oval shape similar to the non-circular hole 70c. An annular lip portion 71b that is smaller than the non-circular hole 70c and has a pointed tip is formed at an intermediate position in the axial direction of the seal hole 71a. The lip portion 71b is formed so as to protrude in contact with the entire surface of the non-circular portion 8c.

  Thus, since the non-circular hole 70c that engages with the non-circular portion 8c and the seal member 71 that contacts and seals the non-circular portion 8c are arranged side by side in the axial direction, the spool support shaft 8 and the connecting member A non-circular gap that is difficult to seal with a certain pressing member 61 can be reliably sealed, and the non-circular hole 70c engages with the non-circular portion 8c, so that deformation of the seal member during drag operation can be suppressed. In addition, since the clearance on the outer peripheral side of the pressing member 61 is also sealed by the seal ring 72, the liquid is less likely to enter the drag storage space 7j. Further, since the lip portion 71b is provided in the seal member 71, the sliding resistance with the spool support shaft 8 is reduced, the pressing member 61 can be smoothly attached and detached, and the drag force when the drag adjusting portion 57 is rotated in the slack direction. Decreases smoothly.

  Between the operation member 60 and the pressing member 61, a drag knob sound generation mechanism 54 that emits sound when the operation member 60 is rotated to adjust the drag is mounted.

  As shown in FIG. 2, the friction portion 58 is mounted between the pressing member 61 and the mounting disc portion 7 e of the spool body 7. The friction part 58 includes first disks 76a and 76b that are non-rotatably connected to the non-circular part 8c of the spool support shaft 8, and a second disk with ears that is non-rotatably connected to the inner peripheral surface of the bobbin trunk 7a. 77, and a drag disk 78 disposed between the two first disks 76a and 76b and the second disk 77 and between the first disk 76b and the mounting disc portion 7e. The first disk 76 a is in contact with the pressing member 61 and is pressed by the pressing member 61. Since the first disk 76a cannot rotate with respect to the spool support shaft 8, it does not rotate relative to the pressing member 61. A seal member 71 is in contact with the front surface of the first disk 76a. The second disk 77 is non-rotatably connected to the bobbin trunk 7a by the ear 77a protruding in the radial direction being locked in the locking groove 7g. The friction portion 58 is prevented from coming off by a retaining spring 73.

<Reel operation and movement>
In this spinning reel, the bail arm 40 is brought down to the yarn releasing posture when the yarn is fed out during casting or the like. As a result, the fishing line is fed out in order from the front end side of the spool 4 due to its own weight. At this time, since the flange protective ring 25 made of a hard material having a large specific gravity is disposed on the outer peripheral portion which is easily damaged by contacting with the fishing line of the flange portion 7c, the wear resistance and durability of the outer peripheral portion of the flange portion 7c are maintained. can do.

  At the time of yarn winding, the bail arm 40 is returned to the yarn winding posture side. When the handle assembly 1 is rotated in the yarn winding direction, this is automatically performed by the action of a bale reversing mechanism (not shown). The rotational force of the handle assembly 1 is transmitted to the pinion gear 12 via the master gear shaft 10 and the master gear 11. The rotational force transmitted to the pinion gear 12 is transmitted from the front portion 12a to the rotor 3 and is transmitted to the oscillating mechanism 6 by the intermediate gear 23 that meshes with the pinion gear 12 via the speed reduction mechanism. As a result, the rotor 3 rotates in the yarn winding direction and the spool 4 reciprocates back and forth.

  When a fish is applied to the device, the drag mechanism 9 may be operated by pulling the fish and the spool 4 may be reversed. During the drag operation, the first disks 76 a and 76 b cannot rotate with respect to the spool support shaft 8, and the second disk 77 cannot rotate with respect to the spool 4, and therefore the first disk 76 a via the drag disk 78. , 76b and the second disk 77 slip. The drag force at this time is determined by the pressing force of the pressing member 61 to the first disk 76a set by turning the operation member 60 of the drag adjusting unit 57.

  When the spinning reel is washed with water, for example, if it is immersed in a bucket filled with water, the water tends to enter the drag storage space 7j inside the spool 4. However, the seal member 71 seals between the inner peripheral portion of the pressing member 61, which is a gap on the inner peripheral side of the drag storage space 7j, and the spool support shaft 8, and the pin member and the bobbin, which are gaps on the outer peripheral side. Since the space between the inner peripheral surface of the body portion 7a is sealed by the seal ring 72, it is possible to reliably prevent liquid from entering the drag storage space 7j.

  Further, since the spool 4 having the drag mechanism 9 can be attached / detached by the one-touch attaching / detaching mechanism 65, it is not necessary to turn the operation member 60 when attaching / detaching. For this reason, even if the spool 4 is attached and detached, the setting of the drag force does not change. Therefore, the drag force and the size of the fishing line can be appropriately set for the plurality of spools 4 according to the fish species to be fishing.

<Other embodiments>
(A) In the above-described embodiment, the present invention has been described by taking the pressing member mounted on the spool of the deep groove type spinning reel that can be attached and detached with one touch as an example, but the connecting member of the present invention is not limited to this. For example, the present invention can be applied to a pressing member or a first disk that is mounted on the spool shaft so as not to rotate directly.

  (B) In the embodiment, the seal member 71 is integrally formed with the main body member 70 by insert molding. However, the seal member may be provided separately from the main body member.

  (C) In the above embodiment, the present invention has been described by taking the pressing member of the spinning reel as an example. However, the present invention can also be applied to a connecting member that is non-rotatably mounted on the handle shaft and spool shaft of the dual-bearing reel. In FIG. 8, a star drag mechanism 109 is mounted on a handle shaft 110 as a shaft member of a dual-bearing reel. The star drag mechanism 109 brakes the rotation of the spool 112 in the yarn unwinding direction via the main gear 120. The star drag mechanism 109 includes a star drag 103 as an operation member that is screwed onto the handle shaft 110, a drag washer (an example of a connecting member) 161 that is non-rotatably mounted on the handle shaft, a drag washer 161, and the main gear 120. And a drag disk 162 disposed between the two. The handle shaft 110 has a non-circular portion 110b having a pair of chamfered portions 110a parallel to each other on the outer peripheral surface. The handle shaft 110 is prohibited from rotating in the yarn unwinding direction by the one-way clutch 125 mounted on the reel body 102, and can rotate only in the yarn winding direction.

  The drag washer 161 is non-rotatably engaged with the non-circular portion 110b, rotates integrally with the handle shaft 110, and has a non-circular hole 170a to which the inner ring 125a of the one-way clutch 125 is coupled so as to be integrally rotatable. And a seal member 171 having a seal hole 171a arranged in the axial direction in the non-circular hole 170a. The non-circular hole 170a has a pair of engagement surfaces (not shown) similar to those of the above-described embodiment that engage with the chamfered portion 110a in a non-rotatable manner. Further, in addition to the engagement surface, there is also an engagement recess (not shown) that engages with a pair of locking projections 125b formed to protrude inward in the axial direction on the inner ring 125a of the one-way clutch 125. . As a result, the inner ring 125a can also rotate integrally with the handle shaft 110. Note that the seal hole 171a does not have a recess corresponding to the engagement recess, and is formed so as to contact the entire circumference of the outer peripheral surface of the handle shaft 110. The seal member 171 is an elastic member made of the same material as that in the above embodiment, and has a lip portion (not shown) in the seal hole 171a. The seal member 171 is integrally formed with the main body member 170 by insert molding. Further, the seal member 171 is formed so as not to come into contact with the main gear 120 that is disposed adjacent to the drag washer 161 and relatively rotates during drag operation. Thus, since the seal member 171 is arranged so as not to contact the adjacent member that relatively rotates, even if the drag washer 161 that is the connecting member and the adjacent member rotate relatively, no frictional force is generated in the seal member 171. For this reason, damage and peeling of the seal member due to generation of frictional force can be reliably prevented.

  The drag washer 161 having such a configuration also has the same effect as the above embodiment.

  (D) In the said embodiment, although this invention was demonstrated to the example for the connection member (pressing member and drag washer) provided in the drag mechanism, this invention is not limited to these, For example, spinning which has a non-circular part The present invention can also be applied to an inner ring of a rotor or a one-way clutch that is connected to a pinion gear of a reel so as not to be relatively rotatable.

  In FIG. 9, the pinion gear 12 is a cylindrical member through which the spool shaft 15 can pass, and is rotatable with respect to the spool shaft 15. The spool shaft 15 is supported by the pinion gear 12 so as to be rotatable and axially movable. The pinion gear 12 has a chamfered portion 12c as a non-circular portion 12b on the outer peripheral surface. The chamfered portion 12c is formed from the front portion 12a of the pinion gear 12 to the front side of the gear portion 12d.

  An inner ring (an example of a connecting member) 253 of the one-way clutch 51 of the reverse rotation prevention mechanism 50 is connected to the pinion gear 12 so as not to be relatively rotatable. A cap member 257 for assisting sealing is interposed between the inner ring 253 and the boss portion 42 of the rotor 3. The cap member 257 is mounted so as to cover the outer peripheral surface and the end surface of the end portion of the boss portion 42 of the rotor 3, and is disposed between the inner ring 257 and the boss portion 42. The inner ring 253 includes a main body member 255 having a non-circular hole 255a that engages with the chamfered portion 12c, and a seal member 256 having a seal hole 256a arranged in the non-circular hole 255a in the axial direction. The non-circular hole 255a has a pair of engaging surfaces (not shown) similar to those in the above-described embodiment that engage with the chamfered portion 12c in a non-rotatable manner. The seal member 256 is an elastic member made of the same material as that of the above embodiment, and has a lip portion (not shown) in the seal hole 256a. The seal member 256 is integrally formed with the main body member 255 by insert molding. The main body member 255 is in contact with the cap member 257, thereby preventing deformation of the seal member 256 when the nut 33 is tightened.

  In addition, a washer-shaped seal plate 259 is attached to a cover plate 258 that is disposed in front of the one-way clutch 51 and prevents the inner ring 253 from falling off in order to prevent liquid from entering from the outer peripheral side of the inner ring 253. . The seal plate 259 has an outer peripheral side attached to the inner periphery of the cover plate 258, and an inner peripheral side having a tapered lip is in contact with the outer peripheral surface of the cap member 257.

  By mounting the inner ring 253 having such a configuration on the pinion gear 12, it is possible to prevent liquid from entering the inside of the reel body 2 from the gap between the inner ring 253 and the pinion gear 12. In particular, since the inner ring 253 is formed by machining rather than molding, machining costs increase if the non-circular hole 255a is machined into the same shape as the non-circular portion. For this reason, the non-circular hole 255a is usually formed as a rectangular hole with rounded corners having an engagement surface that engages with the chamfered portion 12c. In this case, the gap with the outer peripheral surface of the pinion gear becomes large, and the liquid easily enters. Thus, by providing such a seal member 256a, it is possible to prevent liquid from entering. Such an embodiment also has the same effect as the above embodiment.
