Description

  The present invention relates to a dual-bearing reel for fishing in which a spool around which fishing line is wound is rotatably supported between side plates of a reel body.

  Generally, in a fishing reel, for example, a double-bearing type reel is provided with a clutch mechanism. When this clutch mechanism is turned on (clutch ON), the rotation of the handle shaft is transmitted to the spool so that the fishing line can be wound around the spool. On the other hand, when the clutch mechanism is operated to disengage (clutch OFF), the spool supported between the side plates of the reel unit can be freely rotated and the fishing line can be discharged to a desired point by the casting operation.

  By the way, as a casting method for discharging a lure to a predetermined point using such a double-bearing type reel, there is a fishing method (pitching, skipping) in which a light fishing lure is used to shake the fishing rod small and fly to the point. When performing this fishing method, if the weight of the spool is heavy, the inertia may be too large to extend the flight distance, and the lure may not fly to a predetermined pond, which may adversely affect the fishing results.

  Therefore, conventionally, through holes are formed in the flanges formed on both sides of the bobbin trunk of the spool, or the flanges are separated into an inner flange and an outer flange and Patent Document 1 and Japanese Patent Laid-Open No. 2004-135242 disclose an outer flange portion formed of a material having a small specific gravity to reduce the mass of the spool peripheral side to reduce the inertia of the spool and improve the spool-free performance during light casting. It is known from US Pat.

Japanese Unexamined Patent Publication No. 10-165057 JP-A-2004-141103

  However, in Patent Document 1, in order to reduce inertia of the spool, eight hole portions are formed at both ends of a bobbin trunk portion integrally formed with a flange portion in the circumferential direction. Has several problems because a plurality of circular hole portions are formed in the circumferential direction in the region including the rising R portion of the flange portion that projects radially outward at both ends of the bobbin trunk.

  That is, in general, a small-diameter fishing line is densely wound between both flanges of the bobbin trunk with a certain constant tension. , A powerful force acts in the direction of expanding outward in the axial direction. Such a force may cause deformation in the hole that has been weakened and weakened in strength, and the outer circumference of the flange may be brought into contact with the frame of the reel body (spool contact phenomenon), or the fishing line may make strong contact with the hole. There is also a possibility that the fishing line will be broken by causing thread scratches and thread habits. In addition, since the position where both flanges are present is generally a position close to the bearing that supports the spool shaft, water droplets from the fishing line containing a large amount of water easily enter the bearing through the hole and easily adhere to the bearing, There is also a possibility that the bearing performance will be deteriorated.

  On the other hand, in Patent Document 2, as described above, the outer flange portion (magnesium alloy, synthetic resin) having a smaller specific gravity than the inner flange portion (aluminum alloy) is outsert-molded to affect the inertial force during spool rotation. Although the outer flange part is made easier to reduce the weight, the flange part is a part that is formed to be thin (about 0.5 mm) in order to reduce the weight of the entire rotating spool, so another material is combined (outsert molding). It is very difficult to manufacture and the strength is not stable, resulting in high manufacturing cost. Further, it is difficult to maintain the rotational weight balance with high precision due to the influence of the combination of different materials, and casting noise (abnormal noise or vibration) may occur, which may deteriorate the casting performance.

  The present invention has been made in view of the above-mentioned problems, and it is possible to effectively reduce the weight without hindering the strength and to improve the flight distance (improvement of the light cast performance) of a light lure or the like. An object of the present invention is to provide a double bearing type reel including

In order to solve the above-mentioned problems, the present invention supports a spool, which is rotatable by operating a handle provided on one side of the side plates, between left and right side plates configured by attaching a cover to a side portion of a frame. In the dual-bearing reel as described above, the spool includes a bobbin trunk around which fishing line is wound, and flanges formed on both sides of the bobbin trunk, wherein the flange is formed on the bobbin trunk. It is composed of a large-diameter flange portion provided on one side and a small-diameter flange portion provided on the other side of the bobbin trunk, and the large-diameter flange portion and the above-mentioned large-diameter flange portion are provided on the side portions of the respective frames of the left and right side plates. A fitting portion is formed in which the outer circumference of the small-diameter flange portion is fitted with a minute gap, and the large-diameter flange portion has an exposed state where the fishing line wound around the bobbin trunk does not reach so that a summing operation can be performed. Done, Serial characterized Rukoto formed by a separate material than the small-diameter flange portion.

  According to the above configuration, the fishing line is wound around the bobbin trunk with the small-diameter flange portion as the base to perform the casting operation, but since the spool weight on the small-diameter flange portion side is reduced, the inertial force of the spool can be reduced. Cast performance (distance such as a light lure) can be improved. In addition, the weight of the spool can be reduced (the inertial force of the spool can be reduced) without providing a hole or the like in the flange portion, so that the strength of the spool and the poor rotational balance do not occur. Further, according to the above configuration, the summing operation can be easily performed at the time of casting by using the exposed large-diameter flange portion that the fishing line wound around the bobbin trunk does not reach.

  Further, according to the above configuration, due to the difference in outer diameter between the small-diameter flange portion and the large-diameter flange portion, and the fitting portions where the outer circumferences of the large-diameter flange portion and the small-diameter flange portion are fitted with a minute gap therebetween are left and right side plates. Since they are formed on the side portions of the respective frames, the occurrence of thread catching can be effectively suppressed especially on the large-diameter flange portion side.

  In the above configuration, the annular spacer that forms a minute gap between the fitting portion of the frame on the side of the small-diameter flange portion or the supporting member fitted to the fitting portion of the frame is formed between the outer periphery of the small-diameter flange portion. It is preferably mounted. In this way, the spacer compensates for the difference in diameter between the small diameter flange portion and the large diameter flange portion, and an existing frame (of the reel unit main body) incorporating a normal spool having the same flange diameter on both sides of the bobbin trunk is used. The frame that constitutes the side plate) can be used, and compatibility can be ensured. Therefore, the spool can be attached / detached to / from the reel body not only from the side of the large-diameter flange portion but also from the side of the small-diameter flange portion (for spool replacement, maintenance, elimination of thread catching trouble, etc.).

  In addition, in the configuration in which such a spacer is provided, it is preferable to form an annular recess in the spacer into which the outer peripheral edge portion of the small diameter flange portion fits with a minute gap. By doing so, it is possible to realize a labyrinth structure in which the fitting portion and the annular recess are combined, so that it is possible to prevent complicated fishing line catching such that the fishing line penetrates deep into the fitting portion. .

  Further, it is preferable that the spacer is fixed to the support member and is attachable to and detachable from the fitting portion of the frame. With such a configuration, it is easy to remove the cover from the frame and attach and detach the spool.

  Needless to say, in the above-described configuration, in order to reduce the weight and improve the design, holes may be formed in the radially outer portion of the large-diameter flange portion in a penetrating state or a non-penetrating state.

  According to the present invention, it is possible to obtain a dual-bearing type reel provided with a spool that can effectively realize weight reduction without affecting strength and can improve flight distance of light lures (improvement of light cast performance).

The handle 70 is attached to a protruding end of a handle shaft 70a rotatably supported by the left side plate 1A, and when the handle 70 is wound and operated, its rotational driving force is changed to the left frame 2a and the left cover 3a. It is transmitted to the spool 5a (spool shaft 5) via a power transmission mechanism 8 installed between and.

  The power transmission mechanism 8 includes a drive gear 10 rotatably supported by the handle shaft 70 a and a pinion gear 12 meshing with the drive gear 10. The pinion gear 12 of the present embodiment is arranged coaxially with the spool shaft 5, and is rotatably supported by a pressing shaft 14 that comes into contact with the end surface of the spool shaft 5 with a predetermined pressing force by a spool free adjusting mechanism 30. . Both ends of the pinion gear 12 are rotatably supported by the bearing 9 with respect to the left side plate 1A.

  The pinion gear 12 is axially movable along the pressing shaft 14 so as to be disengaged from the spool shaft 5, and is engaged with the spool shaft 5 by the clutch mechanism 17 to be integrated with the spool shaft 5. It is moved between an engagement position (power transmission state) that rotates to the end and a non-engagement position (power interruption state) where the engagement state with the spool shaft 5 is released.

  As is well known, the clutch mechanism 17 includes a yoke 17a that engages with a circumferential groove 12a formed on the outer periphery of the pinion gear 12, a clutch drive member 17b that drives the yoke 17a in the axial direction, and a clutch drive member 17b. It is provided with a clutch lever 17c for moving the yoke 17a in the axial direction via the clutch lever 17c to switch between a clutch ON state and an OFF state. The clutch ON state shown in the figure (the state in which the pinion gear 12 is joined to the spool shaft 5) is provided. ), The pinion gear 12 slides to the left side in the figure, the connection state with the spool shaft 5 is released, and the power is cut off. As is well known, the clutch mechanism 17 is returned to the ON state by rotationally driving the handle 7 in the fishing line winding direction or performing a return operation of the clutch lever 17c.

  A known drag mechanism 19 is installed between the handle shaft 70a and the drive gear 10 so that a desired braking force can be applied to the spool 5a when a fish is caught and a fishing line is paid out. Has become. A one-way clutch 20 is installed between the handle shaft 70a and the left cover 3a so that the handle shaft 70a can be rotated only in the fishing line winding direction. In the figure, reference numeral 58 is a known braking mechanism that applies a braking force to suppress excessive rotation of the spool 5a in the free rotation state during casting.

  Further, between the left and right side plates 1A and 1B, a level wind mechanism 22 is installed on the front side of the spool 5a. As is well known, the level wind mechanism 22 engages with the interlocking gear 22a that meshes with the drive gear that rotates integrally with the handle shaft 70a, the screw shaft 22b that integrally rotates with the interlocking gear 22a, and the screw shaft 22b that is not shown. The fishing line guide body is provided, and by rotating the handle 7, the screw shaft 22b is rotated to reciprocate the fishing line guide body in the left-right direction.

  Therefore, according to the above-described configuration, by winding the handle 70, the spool 5a is rotationally driven via the drive gear 10, the pinion gear 12, and the like, and the level wind mechanism 22 moves the fishing line guide body in the left-right direction. The fishing line is evenly wound around the spool 5a.

  As clearly shown in FIG. 2, the spool 5a of the present embodiment has a cylindrical bobbin trunk 5A around which fishing line is wound, and a circle formed so as to extend from both sides of the bobbin trunk 5A in the radial direction. It is provided with annular flange portions 5B and 5C. In this case, the flange portions 5B and 5C are the large diameter flange portion 5B provided on one side of the bobbin trunk 5A, the left side plate 1A side in the present embodiment, and the other side of the bobbin trunk 5A, the right side plate in the present embodiment. It is composed of a small-diameter flange portion 5C provided on the 1B side. Further, the outer diameter of the large-diameter flange portion 5B (for example, φ32 to φ36 mm) is set to be larger than the outer diameter of the small-diameter flange portion 5C (for example, φ26 to φ30 mm), so that the bobbin trunk portion 5A has almost the same diameter as the small-diameter flange portion 5C. The fishing line can be wound up to the maximum outer diameter (the outermost diameter of the line wound by the broken line L in FIG. 2). The large-diameter flange portion 5B and the small-diameter flange portion 5C are made of the same material as the bobbin trunk 5A, but may be made of different materials.

  Further, in the present embodiment, on the side portion of the left frame 2a of the left side plate 1A, an outer peripheral edge portion of the large-diameter flange portion 5B, specifically, a short tubular fitting portion 5Ba extending in the axial direction is provided with a minute gap s. A fitting portion (fitting hole) 62 for fitting and fitting is formed. Similarly, also on the side portion of the right frame 2b of the right side plate 1B, a fitting portion (fitting portion) for fitting the outer peripheral edge portion of the small-diameter flange portion 5C, specifically, a short tubular fitting portion 5Ca extending in the axial direction. A hole 61 is formed. In this embodiment, the inner diameters of the fitting portions 61 and 62 are set equal to each other so that the spool 5a can be attached to and detached from the reel body 1 from both the handle side and the non-handle side, but they may be different.

  Further, in the present embodiment, the annular spacer 40 is fitted in the fitting portion 61 so as to compensate for the difference in diameter between the small diameter flange portion 5C and the large diameter flange portion 5B, and this spacer 40 has a small diameter flange portion 5C. The outer peripheral edge portion (fitting portion 5Ca) is fitted with a minute gap s therebetween (the minute gap s is formed between the outer periphery of the small diameter flange portion 5C) and an annular recess 40a is formed.

  In this case, the spacer 40 is, for example, a support member that constitutes a known opening / closing mechanism that allows the right cover 3b to be opened and closed with respect to the right frame 2b (allows the right cover 3b to be attached to and detached from the right frame 2b). Set plate 63 (for example, a switching member for switching the open / closed state of the open / close mechanism is mounted). In particular, in the present embodiment, the set plate 63 and the spacer 40 are such that the fitting convex portion 40b of the spacer 40 is fitted into the concave portion 63b formed in the mounting annular convex portion 63a of the set plate 63 (for example, fixed by an adhesive). The right frame 2b (fitting portion) so that the annular convex portion 63a of the set plate 63 and the spacer 40 fit in the fitting portion (fitting hole) 61 of the right frame 2b in the integrally assembled state. 61) is detachably attached. An O-ring 93 is inserted between the spacer 40 and the set plate 63.

  Here, for attachment / detachment of the spool 5a to / from the reel body 1 from the side of the small diameter flange portion 5C, the right frame 2b is opened by the right cover 3b using the opening / closing mechanism described above (for example, the right cover 3b is removed from the right frame 2b). It becomes possible by. On the other hand, the spool 5a can be attached to and detached from the reel body 1 from the large-diameter flange portion 5B side by using various known attachment and detachment techniques.

  As described above, according to the double-bearing reel of the present embodiment, the fishing line is wound around the bobbin trunk 5A based on the small-diameter flange portion 5C to perform the casting operation, but the spool on the small-diameter flange portion 5C side is used. Since the weight can reduce the inertial force of the spool 5a, the light cast performance (the flight distance of a light lure or the like) can be improved. Further, since the weight of the spool 5a can be reduced (the inertial force of the spool 5a can be reduced) without providing holes or the like in the flange portions 5B and 5C, it is possible to prevent the strength of the spool 5a from being lowered and the rotation balance to be poor. Further, according to the configuration of the present embodiment, at the time of casting, the exposed large-diameter flange portion 5B (the portion 85 on the radially outer side of the large-diameter flange portion 5B that the fishing line wound around the bobbin trunk portion 5A does not reach (see FIG. It is also possible to easily perform the summing operation using (2))).

  Further, according to the present embodiment, due to the difference in outer diameter between the small-diameter flange portion 5C and the large-diameter flange portion 5B, the outer circumferences of the large-diameter flange portion 5B and the small-diameter flange portion 5C are fitted with a minute gap s. Since the fitting portions 61, 62 to be formed are formed on the side portions of the frames 2a, 2b of the left and right side plates 1A, 1B (and / or by the annular recess 40a), the occurrence of thread catching is caused especially on the large-diameter flange portion 5B side. It can also be effectively suppressed.

  Further, in the present embodiment, the annular spacer 40 that forms the minute gap s with the outer periphery of the small diameter flange portion 5C is attached to the set plate (support member) 63 that is fitted into the fitting portion 61 of the right frame 2b. Therefore, the spacer 40 compensates for the difference in diameter between the small diameter flange portion 5C and the large diameter flange portion 5B, and an existing spool (not shown) having the same flange diameter on both sides of the bobbin trunk 5A is incorporated. A frame (frame that constitutes the side plate of the reel unit) can be used, and compatibility can be ensured. Therefore, not only from the large-diameter flange portion 5B side, but also from the small-diameter flange portion 5C side, the spool 5a can be attached to and detached from the reel unit 1 (for spool replacement, maintenance, thread clogging, etc.). .

  Further, in the present embodiment, the annular recess 40a into which the outer peripheral edge portion of the small-diameter flange portion 5C is fitted with the minute gap s is formed in the spacer 40. Therefore, the labyrinth according to the combination form of the fitting portion 61 and the annular recess 40a is formed. It is possible to realize a structure, and it is possible to prevent complicated fishing line catching such that the fishing line penetrates deep into the fitting portion 61.

  Further, in the present embodiment, since the spacer 40 is fixed to the set plate 63 and is attachable / detachable to / from the fitting portion 61 of the frame 2b, the work of removing the cover 3b from the frame 2b and attaching / detaching the spool 5a becomes easy. .

  Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, in order to reduce the weight and improve the design, a hole 85 is formed in the radially outer portion 85 (see FIG. 2) of the large-diameter flange portion 5B in a penetrating state or a non-piercing state (not shown). It may be formed. Further, in the above-described embodiment, the spacer 40 is eliminated, and the fitting portion 5Ca of the small-diameter flange portion 5C has a minute gap in the fitting portion (fitting hole) 61 of the frame 2b, similarly to the large-diameter flange portion 5B side. Then, it may be directly fitted. In that case, since the inner diameter of the fitting portion 61 is smaller than the inner diameter of the fitting portion 62, the spool 5a is generally attached / detached to / from the reel body 1 only from the non-handle side.
