Description

The present invention relates to a spinning reel for fishing, and more particularly to a spinning reel for fishing that has features in its rotor portion.

A spinning reel for fishing has a structure that includes a rotor that rotates in conjunction with a spool that moves back and forth by the winding and rotation operation of the handle.The rotor has a pair of support arms that rotate around the spool. ) are integrally formed. A bail support member (arm lever) is supported at the tip of each of the pair of support arms so as to be rotatable between a fishing line winding position and a fishing line releasing position, and a fishing line guide device is attached to one bail support member. has been done. Furthermore, the base end of the bail that picks up the fishing line is connected to each bail support member, and the bail is rotated (reversed) between the fishing line winding position and the fishing line release position as the bail support member rotates. It looks like this.

The spool includes a fishing line winding body portion around which the fishing line is wound, a front flange portion that defines the winding amount of the fishing line on the front side, and a rear flange portion (skirt portion) that defines the amount of winding of the fishing line on the rear side, By rotating the bail to the fishing line release position, the fishing line is released in a spiral shape from the fishing line winding body. Further, when the bail is reversed and returned to the fishing line winding position, the fishing line is picked up by the bail and guided to the fishing line winding body of the spool via the fishing line guide section (line roller) of the fishing line guide device. As a result, when the handle provided on the reel body is operated to wind up, the spool is reciprocated back and forth in synchronization with the rotating operation of the handle, and the fishing line is provided on the rotor and rotates around the spool. The guide portion allows the fishing line to be evenly wound around the fishing line winding body.
Further, the reversing mechanism for reversing and returning the bail is housed inside one of the support arms, and by attaching a cover member to the front side of the support arm with a screw member, the reversing mechanism is housed without being exposed. .

By the way, in a spinning reel for fishing, a pair of support arms and a bail support member are located around the spool around which the fishing line is wound, so when releasing or winding the fishing line, the surroundings of these support arms etc. The thread is likely to become tangled near the rotor, and in some cases, the thread may fall inside the rotor. Furthermore, if a screw member (attachment member) for fixing or rotatably supporting a functional member such as the cover member to another member is exposed, it may cause thread entanglement.

Therefore, Patent Document 1 discloses a configuration in which the fixing screws of the cover member attached to the front surface side of the support arm are attached from the inside of the rotor, so that the head of the fixing screw and the recess for attachment are not exposed to the front surface side. This disclosure is intended to prevent the fishing line from getting caught on the fixing screw, to prevent the fixing screw from rusting, and to improve the appearance.

JP 2002-027875

Merely preventing the fixing screw of the cover member from being exposed from the surface of the support arm as in the above-mentioned known technology is not sufficient as a countermeasure against thread entanglement. That is, in the spinning reel for fishing disclosed in Patent Document 1, as shown in FIG. 2, the screw for fixing the line slider constituting the fishing line guide part and the recess for attachment are exposed on the outer surface. , There are insufficient measures to prevent thread entanglement with screws. In addition, due to the influence of slackness of the fishing line, twisting of the line, posture of the reel, etc. during actual fishing, when the fishing line falls to the rear of the rotor, it tends to become entangled in the connection between the cylindrical part of the rotor and the support arm, causing the fishing line to guide the fishing line. Measures against thread entanglement are insufficient for the rotor body equipped with the device.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a spinning reel for fishing equipped with a rotor that does not easily cause line entanglement during actual fishing.

In order to achieve the above object, a spinning reel for fishing according to the present invention moves back and forth by rotating a handle rotatably supported on a reel body, and has a spool around which a fishing line is wound, and a spool attached to the handle. A rotor that rotates by a rotation operation, a pair of bail support members that are distributed and held by a reversing mechanism at a fishing line winding position and a fishing line release position on a pair of support arms provided on the rotor, and the pair of bail support members are A fishing line guide section attached to one side, a line roller disposed between the bail support member and the fishing line guide section for guiding the fishing line to the spool, and a reversing mechanism housed in the support arm are closed. a cover member that closes the opening of the support arm, and a mounting member that attaches each of the fishing line guiding section, the bail support member, and the cover member to the cover member; It is characterized in that it is arranged so as not to be exposed from the outer surface of the rotor and bail supporting member included therein.

In the spinning reel for fishing having the above-mentioned configuration, the attachment member for attaching each of the fishing line guiding portion, the bail support member, and the cover member is connected to the rotor including the cover member and the bail support member in the area around the rotor. By configuring the fishing line so that it is not exposed from the outer surface, entanglement of the fishing line can be effectively prevented when the fishing line is released/taken up during actual fishing. Note that the attachment member may be, for example, a screw member, a member in which an E-type retaining ring is attached to an insert-molded pin, a self-tapping screw, etc., and is not limited to a specific structure.

According to the present invention, it is possible to obtain a spinning reel for fishing equipped with a rotor that does not easily cause line entanglement during actual fishing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fishing spinning reel according to the present invention will be specifically described with reference to the drawings.
1 to 3 are diagrams showing an example of the configuration of a fishing spinning reel according to an embodiment of the present invention. First, an overview of the overall configuration of a fishing spinning reel will be explained. In addition, in the following description, the front and rear of the rotor mean the directions shown in FIGS. 1 and 2.

A reel body 2 of a fishing spinning reel 1 is formed with a leg portion 2A that is attached to a fishing rod. A handle shaft is rotatably supported within the reel body via a bearing, and a handle 3 that is operated for winding is attached to an end of the handle shaft. Further, a known driving force transmission mechanism is connected to the handle shaft, and as the handle 3 is rotated, the rotor 10 is rotationally driven, and the spool 5 is moved back and forth via a known oscillating mechanism. It looks like this.

The spool 5 is made of, for example, a metal with a light specific gravity such as aluminum, an aluminum alloy, a magnesium alloy, or a synthetic resin material. It has a front flange portion 5b and a rear flange portion (skirt portion) 5c that define the amount of thread winding of the trunk portion 5a in the front-rear direction.

A pair of support arms 11 and 12 are formed on the rotor 10 so as to extend forward in the axial direction and face each other at approximately 180° intervals, and the spool 5 is located between the pair of support arms. It is driven back and forth. At the tips 11A, 12A of each support arm 11, 12, rotary support parts 14a, 15a of bail support members 14, 15 are rotatably supported between a fishing line winding position and a fishing line release position. (See Figure 4). Further, a base end portion of a semi-annular bail 17 is attached to each of the bail support members 14 and 15, and the bail 17 is rotatable together with the bail support members 14 and 15. A fishing line guide device 50 for guiding the fishing line to the spool is disposed at the tip of one bail support member 15 (see FIG. 2).

As is well known, the fishing line guide device 50 includes a fishing line guiding section (line roller) 51 that guides the fishing line to the spool 5, and a fishing line guiding section (line slider) 53 that guides the fishing line from the bail 17 to the line roller 51. One base end 17a of the bail 17 is connected to the fishing line guiding section 53. The bail 17 has a hollow shape and is integrally connected to the attachment part 53a of the fishing line guiding part 53; It may be configured such that it is coupled to the fishing line guiding section 53, or it may be configured such that it extends directly from the attachment section 53a of the fishing line guiding section 53 and is integrally formed with the fishing line guiding section 53. Further, it is preferable that the attachment part 53a of the fishing line guiding part 53 and the base end part 17a of the bail 17 are connected flush with each other without any difference in level.

1 to 3 show the fishing line winding state, and when the handle 3 is rotated in this state, the rotor 10 is rotationally driven via the driving force transmission mechanism, and the spool 5 is moved back and forth via the oscillating mechanism. It is driven back and forth. Thereby, the fishing line is evenly wound around the fishing line winding trunk 5a of the spool 5 via the line roller 51 of the fishing line guide device 50 of the bail support member 15 that rotates together with the rotor 10.

When the bail 17 is rotated (rotated in the direction of the arrow) from the fishing line winding state shown in the figure to the fishing line release position with the rotation of the bail support members 14 and 15, the fishing line wound around the spool 5 is The state is in a released state (not shown). After releasing the fishing line in this fishing line releasing state, when the bail 17 is rotated from the fishing line releasing position to the fishing line winding position, the fishing line is picked up by the bail 17 and guided to the line roller 51 along the fishing line guiding section 53. Then, the fishing line is wound up as shown in the figure.

The bail 17 is rotated between a fishing line release position and a fishing line winding position, and is distributed and held in either position. In this case, rotation (reversal return) from the fishing line release position to the fishing line winding position is performed manually by grasping the bail 17 by hand, or via a reversing mechanism when the handle 3 is operated to wind the fishing line. Is possible. Since this reversing mechanism is well known, its structure will be omitted, but it can be built into one of the support arms 11 and 12, and it can be built into the support arm 12 on the side to which the fishing line guide device 50 is attached. ing. Therefore, a recess 12B' for accommodating the reversing mechanism is formed on the outside of the support arm 12, and the opening of the recess 12B' is closed by a cover member 12B attached to the support arm 12. (See Figure 8).

The line roller 51 of the fishing line guide device 50 is formed into a cylindrical shape and is rotatably supported between the bail support member 15 and the fishing line guide section 53. The line roller 51 of this embodiment has a known bearing (not shown) interposed in the shaft portion of an attachment member (screw member in this embodiment) 55 that fixes the fishing line guide portion 53 to the bail support member 15. is rotatably supported.

The fishing line guide section 53 is integrally formed of a lightweight and highly slidable metal material, such as a thin film of stainless steel alloy or aluminum alloy, and has a substantially circular opening 53b on the bail support member 15 side. The mounting portion 53a is connected to the base end 17a of the veil 17 on the opposite side of the opening 53b.

Further, the fishing line guide portion 53 is formed with a recess 53A in which the head 55a of the attachment member 55 is accommodated without protruding outward. The recessed portion 53A is formed between a pair of inclined portions 53d that gradually widen and rise on both sides along the axial direction from the mounting portion 53a toward the bail supporting member side. The upper end sides of the pair of inclined parts 53d on both sides of the recessed part 53A are integrated with a ring-shaped annular part 53e, and the bail supporting member side forms the opening 53b. The lower end side is integrated with the mounting portion 53a.

In the above configuration, the attachment member 55 is inserted from the bail 17 side (in the direction of arrow D1 in FIG. 4), and the line roller 51 is rotatably supported with a bearing interposed in the intermediate portion of the shaft portion of the attachment member. There is. Furthermore, the male threaded portion formed at the end of the shaft portion is screwed and fixed to the female threaded portion provided on the inner surface of the bail support member 15, and the fishing line guide portion 53 is fixed to the bail support member 15. . Therefore, as shown in FIGS. 2 and 3, the attachment member 55 for attaching the fishing line guide portion 53 to the bail support member 15 faces the bail 17 side and is exposed from the outer surface of the bail support member 15. Therefore, it is possible to form the outer surface into a smooth surface to suppress entanglement of the fishing line.

Next, the basic structure of the rotor 10 will be explained in detail with reference to FIGS. 4 to 10 in addition to FIGS. 1 to 3.
The main body 10A of the rotor 10 is integrally formed of a lightweight and strong material such as an aluminum alloy, a magnesium alloy, or a hard resin. The pair of support arms 11 and 12 are integrally formed on the main body 10A so as to protrude forward along the spool axis with an interval of approximately 180° between the pair of support arms 11 and 12. A cylindrical portion 20 is formed therein.

The cylindrical wall 21 of the cylindrical portion 20 is closed on the front side by a front wall 22, and has a substantially circular opening at the rear end. A ring-shaped portion 25 is integrally formed at the rear end of the cylindrical wall 21 so as to protrude in the radial direction within substantially the same plane, and this ring-shaped portion 25 forms the rear end of the rotor. Both sides of the base of the support arms 11 and 12 are connected to each other and are integrated with the support arm. The ring-shaped portion 25 may be formed into a single ring shape, but the outer circumferential surface of the ring-shaped portion 25 in this embodiment is arranged along the ring-shaped portion 25 radially outward between the support arms 11 and 12. A curved wall 25a is integrally formed therein. This curved wall 25a is integrated with connecting portions 26a to 26d, which will be described later, and is flush with the surface of the connecting portion, and has a smooth bowl shape whose diameter gradually increases forward from the lower edge of the ring-shaped portion 25. It has a surface shape of

The front wall 22 includes a flat bridge 20A that radially connects the front edge of the opening of the cylindrical wall 21 with a predetermined width, and a cap member 22A that is attached to the surface of the bridge 20A. As shown in FIGS. 4 and 5, the cap member 22A includes a circumferential wall 22a, an annular flange portion 22b projecting radially outward at the upper opening edge of the circumferential wall, and a substantially rectangular opening 22d in the central region. The bottom portion 22c is formed with a bottom portion 22c. The circumferential wall 22a is provided with a pair of arcuate walls 22a' that hang down in an arc shape at two opposing locations, and on the back surface of the bottom portion 22c, there are provided a pair of arcuate walls 22a' that hang down in an arc shape at two opposing locations. A boss 22e is formed on the bridge 20A so that it can be attached to the bridge 20A.

It is preferable to form an opening in the cylindrical wall 21 of the cylindrical portion 20 so as to reduce the weight. The opening in this embodiment is formed in an arc shape along the circumferential direction of the cylinder wall 21 from the upper side of the cylinder wall 21 to the area reaching the ring-shaped part 25, and is opposed to the pair of support arms 11 and 12. Openings 21d and 21e having substantially the same shape are formed in areas other than the certain range of arcuate walls 21a and 21b (see FIGS. 4 to 6).

By forming the openings 21d and 21e as described above in the cylindrical wall 21, the upper end sides of the arcuate walls 21a and 21b are connected by the semi-annular frames 21f and 21g. In this case, by forming the openings 21d and 21e large, the weight of the rotor can be reduced, but if they are formed too wide in the circumferential direction, the strength will decrease. In particular, since a large load is applied to the positions where the support arms 11 and 12 are formed, it is preferable that no openings be formed at least in a certain range of circular arc regions facing the support arms 11 and 12. Further, in this embodiment, the semi-annular frames 21f and 21g are formed at positions lower than the upper end of the cylindrical wall 21, thereby effectively preventing deformation of the arcuate walls 21a and 21b. Become.

The bridge 20A has an opening 20a formed in the center thereof through which the spool shaft is inserted, and a nut for fixing it to the pinion gear. , holes 20b are formed at four locations (which may be any location and the locations are not limited) at positions corresponding to the bosses. As shown in FIG. 5, the bridge 20A is connected to the cylindrical wall 21 of the cylindrical portion 20 between the support arms 11 and 12, and the semi-annular frame 21f, A space is formed between it and 21g.

For such a bridge 20A, the bottom 22c of the cap member 22A is brought into contact with the surface of the bridge 20A, and the boss 22e protruding from the hole 20b is welded (see FIGS. 9 and 10). It is attached to the bridge 20A and forms the front wall 22 together with the bridge (see FIG. 4). In this state, the space between the semi-annular frames 21f and 21g on both sides of the bridge 20A is closed by the bottom 22c of the cap member 22A and the arcuate wall 22a', and the frame-shaped cylindrical wall The upper part 21 can be effectively made lighter and dustproof.

The ring-shaped part 25 has the above-described openings 21d and 21e formed in the cylindrical wall 21 of the cylindrical part 20, so that both sides of the lower ends of the arcuate walls 21a and 21b of the cylindrical wall 21 have a semi-annular frame structure. They have a connected structure, and the connected portion becomes the ring-shaped portion 25 and defines the opening at the rear end of the cylindrical portion 20. In this case, the rear ends of the support arms 11 and 12 are integrally connected to a ring-shaped part 25 having a frame structure, and are integrated with the ring-shaped part 25. As a result, in the rotor main body 10A, the pair of support arms 11 and 12 on which a large load is applied are effectively reinforced, and it is possible to reduce the weight as much as possible while maintaining the necessary strength.
Note that the strength of the rotor can be improved by variously changing the sizes of the openings 21d and 21e formed in the cylindrical wall 21 of the cylindrical portion 20, the thickness of the ring-shaped portion 25, the surface shape, and the cross-sectional shape. At the same time, weight reduction can be effectively achieved.

Although there are no particular limitations on how to connect each side of the support arms 11, 12 and the ring-shaped portion 25 and their connection positions, in this embodiment, the support arms 11, 12 are Connection parts 26a, 26b, 26c, and 26d have a shape that is tapered from the rear end toward the side of the support arm without any step between each side part and the ring-shaped part (rear end of the rotor) 25. connected by forming a

In this case, the support arm 11 on the side where the reversing mechanism is not provided has connection parts 26a, 26b connected to both sides thereof, as shown in FIGS. 1 and 7. is formed into a bifurcated shape by opening the rear side (lower end side) of the support arm 11, and is connected to the ring-shaped portion 25 as it is. That is, a substantially rectangular opening 27 is formed between the connecting portions 26a and 26b, and the bail supporting member 14 is rotatably supported on the outside of the support arm 11 above the opening 27. .
Further, as shown in FIGS. 2 and 8, the support arm 12 on the side where the reversing mechanism is provided has connecting portions 26c and 26d connected to both sides thereof, and one connecting portion 26d. A substantially triangular opening 28 is formed therebetween. Further, the bail support member 15 is rotatably supported on the upper outer side of the support arm 12.

As described above, by forming the above-mentioned openings 27 and 28 in the connection parts and making each connection part tapered toward the front, it is possible to reduce the weight of the main body of the rotor, and the design This makes it possible to improve the In this case, the edges defining each opening 27, 28 may be formed in a direction perpendicular to the surface of the support arm, but as in this embodiment, the edges that define the openings 27, 28 may be formed with an inclination that gradually widens from the inside to the outside. The use of surfaces (slanted edges 27a, 28a) not only improves the design, but also makes it difficult for the fishing line to get tangled, making it possible to effectively prevent line breakage and the like.

The attachment method for rotatably supporting the bail support members 14 and 15 on the support arms 11 and 12 is as shown in FIG. The rotation support portions 14a and 15a of the support members 14 and 15 are abutted, and the attachment member (in this embodiment, the insert This is done by tightening a molded pin with an E-shaped retaining ring (member) 30 (the support arm 11 side is similarly fixed; see FIG. 10). In this case, U-shaped recesses 11a and 12a are formed in the inner surfaces of the distal ends of the support arms 11 and 12, respectively, so that the attachment member 30 inserted from the inside does not protrude. .

As a result, the attachment member 30 is not exposed from the outer surface of the support area of the bail support members 14 and 15, and the outer surface of the bail support member can be made a smooth surface, making it difficult for the fishing line to become entangled. can.

As shown in FIG. 8, a boss 12d is formed on the inner surface of the cover member 12B that closes the reversing mechanism housed in the support arm 12. As shown in FIG. This boss 12d is formed with a female threaded portion (a configuration into which a self-tapping screw is screwed) is formed, and the attachment member (threaded member) 35 is inserted into the boss 12d from the inside in the radial direction in the direction of arrow D3 in FIG. By screwing together, the cover member 12B is attached to the support arm 12. For this reason, a screw hole 12d' is formed in the bottom surface of the recess 12B' that accommodates the reversing mechanism of the support arm 12 at a position corresponding to the boss 12d of the cover member 12B to be attached. By tightening the fixing member 35 in the D3 direction, the cover member 12B is attached to the support arm 12, and the reversing mechanism disposed in the recess 12B' is closed.

In this case, as shown in FIG. 4, openings 21h and 21i are formed in the arcuate walls 21a and 21b of the cylindrical wall 21 of the rotor, respectively, so that the attachment member 35 can be easily fixed. I have to. That is, with the cover member 12B attached to the support arm 12 housing the reversing mechanism, the attachment member 35 and a jig (not shown) for fixing it are attached to the opening 27 of the support arm 11 and the cylindrical wall 21 of the rotor. The cover member 12B can be inserted through the openings 21h and 21i, making it possible to easily attach the cover member 12B.

As a result, the attachment member 35 is not exposed from the outer surface of the cover member 12B attached to the support arm 12, and the outer surface can be made smooth, making it difficult for the fishing line to become entangled.
In addition, in the above-described configuration, the cylindrical portion 20 of the rotor has a plurality of openings 21d, 21e, 21h, and 21i formed in its cylindrical wall 21, and a plurality of openings 21d, 21e, 21h, and 21i are formed through the connecting portions 26a, 26b, 26c, and 26d. Since the ring-shaped portion 25 and the support arms 11, 12 are integrated into a frame structure, it is possible to maintain strength and reduce weight as much as possible. Particularly, the parts of the support arms 11 and 12 on which a large load is applied are reinforced by the arcuate walls 21a and 21b, and are connected to the connecting parts 26a, 26b, 26c, and 26d by the ring-shaped part 25. , good balance and improved strength.

According to the spinning reel for fishing having the rotor 10 as described above, attachment members 55, 30, 35 for attaching the fishing line guide portion 53, the bail support members 14, 15, and the cover member 12B, respectively, are provided. Since the cover member 12B is arranged so as not to be exposed from the outer surface of the rotor 10 and the bail support member 14, line entanglement can be effectively prevented during fishing line winding/fishing line release during actual fishing. It becomes possible.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways.
For example, the shapes of the support arms 11 and 12 and the bail support members 14 and 15 shown in the figures are merely examples, and can be modified as appropriate. In this case, the exposed portion may have irregularities on its surface as long as it is such that the fishing line is hard to get caught in it or can be easily removed even if it gets caught. Regarding the openings formed in the cylindrical wall 21 of the cylindrical part 20 of the rotor, if the strength can be ensured by the ring-shaped part 25 and the connecting parts 26a, 26b, 26c, and 26d, the shape, number of openings, and position of the openings can be determined. can be modified as appropriate. Furthermore, if necessary, an opening other than the one described above may be formed.
