Description

The present invention relates to a spinning reel spool for fishing and a spinning reel for fishing that winds and holds a fishing line.

A spinning reel for fishing has a structure in which a bail for picking up a fishing line is placed in a fishing line releasing state to release the fishing line. The spool includes a fishing line winding body on which the fishing line is wound, a front flange portion that defines the amount of winding of the fishing line on the front side, and a rear flange portion (also referred to as a skirt portion) that defines the amount of winding of the fishing line on the rear side. When releasing the fishing line (trigger), the fishing line is released forward in a spiral from the fishing line winding barrel. When the fishing line is to be wound, 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. As a result, when the handle provided on the reel body is operated to wind, the spool reciprocates back and forth in synchronization with the rotating operation of the handle, and the fishing line guide is provided on the rotor that is rotationally driven and rotates around the spool. The fishing line is evenly wound on the fishing line winding barrel through the section.

As described above, when the fishing line is repeatedly released and wound on the spool, the fishing line wound on the fishing line winding body may become entangled in the skirt in a loop. , fishing line may enter the rotor from the spool due to line dander (also referred to as line dropping). Therefore, in order to prevent such line entanglement, Patent Documents 1 and 2 disclose methods such as forming a taper on the outer peripheral surface of the skirt portion of the spool or forming a circumferential groove so that the fishing line does not drop onto the rotor. It is disclosed to provide a difficult shape.

Patent No. 3922442 Japanese Patent Application Laid-Open No. 2008-118918

As described above, the skirt portion of the conventional spool is designed so as to prevent the line from dropping, but sufficient consideration is not given to facilitating the removal of the tangled fishing line forward. That is, during actual fishing, the fishing line is often caught on the skirt portion, and in such cases, it is preferable that the fishing line is easily pulled forward during the next casting operation in order to eliminate the tangling of the line.

If a taper is formed in the skirt portion as in the above-described prior art, when the fishing line is entangled behind the taper, the fishing line will be caught at the boundary between the taper and the cylindrical portion (position of the inflection ridge line) during the next casting operation. is resisted and cannot effectively exit forward. Similarly, in a configuration in which a circumferential groove is formed on the outer peripheral surface of the skirt portion, the fishing line is likely to enter the circumferential groove portion and cannot be effectively pulled out forward. Furthermore, if you continue to wind the line without noticing a relatively small amount of dander due to a change in tension, the tapered portion of the skirt will inadvertently add resistance when the line is released next time. It is possible.

The present invention has been made in view of the above-described problems, and is a fishing spinning wheel provided with a skirt portion that facilitates the fishing line to be pulled out forward during the next casting operation even if the line is entangled in the skirt portion of the spool. It is an object of the present invention to provide a reel spool and a fishing spinning reel with such a function.

In order to achieve the above object, the spool of the spinning reel for fishing according to the present invention comprises a line winding body around which the fishing line is wound, and a skirt formed on the rear side of the fishing line winding body. , the outer peripheral surface of the skirt portion has a front end portion having a maximum diameter behind the fishing line winding body portion, and gradually decreases in diameter from the front end portion to the rear end portion, and the In the area where the diameter is reduced, the curved surface is formed without a step from the rear to the front end.

With the above-described spool, even if the line gets entangled in the skirt portion during actual fishing, the curved surface of the spool allows the line to be easily pulled out forward when the line is released by casting. That is, when the fishing line slides forward, the curved surface does not have a step such as a ridge line or an inflection point. It slides without being caught, and as a result, it is possible to effectively suppress the thread entanglement phenomenon.

Further, the present invention is characterized by a spinning reel for fishing equipped with a spool having a skirt portion as described above.

ADVANTAGE OF THE INVENTION According to the present invention, there is provided a spinning reel spool for fishing that allows the line to be easily pulled out forward during the next casting operation even if the line is entangled in the skirt portion of the spool, and a spinning for fishing equipped with such a function. You get a reel.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the spool of the spinning reel for fishing according to the present invention and the spinning reel for fishing equipped with such a spool will be specifically described with reference to drawings.
FIG. 1 is a diagram showing one configuration example of a spinning reel for fishing equipped with a spool according to one embodiment of the present invention, and FIG. It is a figure which expands and shows a principal part.

First, with reference to FIG. 1, an outline of the overall configuration of a spinning reel for fishing will be described.
In the present invention, the front side (front end) of the skirt of the spool means the left side in FIG. means.

A reel body 2 of a spinning reel 1 for fishing is provided with a reel leg 2a attached to a fishing rod. A spool 20 is provided which is operably supported and on which fishing line is wound.

A handle shaft 9a is rotatably supported in the reel body 2, and a handle 9 is attached to the protruding end of the handle shaft 9a. A take-up drive mechanism 10 is engaged with the handle shaft 9a. As is well known, the take-up drive mechanism 10 is attached to a handle shaft 9a and has a drive gear (drive gear) 11 formed with internal teeth. and a pinion gear 12 having an axially extending hollow portion formed therein.

A spool shaft 20S that rotatably supports the spool 20 is inserted through the pinion gear 12 so as to be axially movable back and forth. A known oscillating mechanism 14 is engaged with the rear side of the spool shaft 20S, and when the handle 9 is rotated, the spool 20 is reciprocated back and forth via the oscillating mechanism and the spool shaft. Further, the rotor 5 is fixed to the pinion gear 12 by tightening a rotor nut 12a on the front side of the pinion gear 12. As shown in FIG.

As is well known, the rotor 5 is formed with a pair of support arms extending axially forward and facing each other at an interval of approximately 180°, and the spool 20 is positioned between the pair of support arms. It is then reciprocated back and forth. An arm lever 6 (only one of which is shown in FIG. 1) is rotatably supported at the tip of each support arm between a fishing line winding position and a fishing line releasing position. A base end of a semi-annular bail 7 is attached to each arm lever 6 , and the bail 7 is rotatable together with the arm lever 6 . A fishing line guide device (line roller) 8 is arranged at the tip of one arm lever 6, as shown in FIG.

FIG. 1 shows a fishing line winding state. When the handle 9 is rotated in this state, the rotor 5 is rotationally driven via the winding drive mechanism 10, and the spool 20 reciprocates back and forth via the oscillator mechanism 14. driven. As a result, the fishing line is evenly wound around the spool 5 via the fishing line guide device 8 that rotates together with the rotor 5 . When the bail 7 is rotated from the fishing line winding state shown in FIG. 1 to the fishing line releasing position with the rotation of the arm lever 6, the fishing line wound around the spool 20 is released. After the fishing line (trigger) is released in this fishing line releasing state, the bail 7 is rotated from the fishing line releasing position to the fishing line winding position. The fishing line winding state shown in .

Next, the configuration of the spool 20 will be described with reference to FIGS. 1 and 2. FIG.
The shape of the spool 20 described below is specified by the shape showing one side surface as shown in FIG. It is

The spool 20 is made of a metal having a low specific gravity such as aluminum, an aluminum alloy, or a magnesium alloy, or a synthetic resin material. It has a front flange portion 20B and a rear flange portion (skirt portion) 20C that define the amount of line wound in the front-rear direction.

The outer peripheral surface of the skirt portion 20C is provided with a front end portion 21 that defines a line winding amount at a rear position of the fishing line winding body portion 20A, and the diameter of the front end portion 21 defines the line winding amount. The skirt portion 20C has a region whose diameter gradually decreases from the front end portion 21 toward the rear end portion 22. In this region where the diameter decreases, the curved surface 23 has no step from the rear to the front end. consists of The skirt portion 20C of this embodiment is formed so that the front end portion 21 has the maximum diameter of the skirt portion 20C, and the diameter gradually decreases toward the rear end portion 22 over the entire length L in the longitudinal direction. , and this area is composed of a single curved surface without steps.
Here, "no step" means that, in the above-mentioned gradually decreasing area, there is no ridgeline (a ridgeline caused by the intersection of surfaces) where compound surfaces intersect and become an inflection point. If no ridge line is formed, the curved surface also includes a curved surface composed of multiple surfaces.

Since the skirt portion 20C is composed of a smooth curved surface in this way, even if the fishing line is caught on the skirt portion, the surface of the skirt portion does not cause any resistance when the next tackle is released, and the front of the skirt portion 20C does not cause any resistance. It is possible to slide (get out of) the thread, and the thread entanglement can be eliminated. In addition, the curved surface gradually decreases in diameter toward the rear, thereby making it possible to reduce the weight of the spool. Further, by providing the maximum diameter portion of the skirt portion immediately behind the fishing line winding body portion 20A, it is possible to reduce the line dropping phenomenon.

The curved surface 23 described above is preferably formed over the entire length L of the skirt portion 20C. The fishing line can be easily pulled out. Specifically, the forming length L1 of such curved surface 23 may be formed in a range of 80% or more of the total length L of the skirt portion.

Further, the curved surface 23 is preferably surface-treated to have a surface roughness Ry of 1.0 μm or less so that the fishing line can easily slide. Such surface treatment includes, for example, when cutting the surface of the skirt portion 20C, using a cutting tool having an R tip, the cutting is performed so that the grain is not visible, or various mirror finishing processes are performed. It is possible to realize with Alternatively, if it is a spool made of resin, it can be realized by mirror-finishing the surface, such as plating.

For example, the curved surface formed on the skirt portion 20C can be configured as follows. Another embodiment of the spool will be described below, but the same reference numerals are given to the same parts as in the above-described embodiment, and detailed description thereof will be omitted.

FIG. 3 shows a second embodiment of the spool.
As noted above, the curved surface may be composed of compound surfaces, provided that no ridges are formed. For example, the curved surface 33 shown in FIG. 3 has a compound surface including two curved portions 33a and 33b with different curvature radii. It is formed so as to be radially outward, opposite to the spool shaft. In this case, the skirt portion 20C begins to decrease in diameter rearward from the curved portion 33a, and also gradually decreases in diameter from the curved portion 33b to the rear end portion 22. In the range up to , the shape is such that the ridge does not appear.

In this way, even if the curved surface has a plurality of curved portions, if there is no ridgeline at the boundaries between them, the fishing line will not get caught and can be easily pulled out forward. When the curved portion is formed of a plurality of surfaces, it is preferable that the radius of curvature of the side surface along the axial direction of the curved portion is large so that the fishing line can be easily pulled out. Specifically, it preferably includes a curved surface (corresponding to the curved portion 33b in the figure) with R10 (curvature radius of 10 mm) or more, and all curved portions may be configured with R10 or more.

FIG. 4 shows a third embodiment of the spool.
In this embodiment, a projection 25 for preventing thread dropout is formed on the outer peripheral surface of the rear end portion of the skirt portion 20C of the second embodiment. The convex portion 25 is configured as a ring-shaped flange that bulges in the radial direction at the rear end position 33c of the curved surface 33. By forming such a convex portion 25, the fishing line can be pulled from the skirt portion. Dropping into the rotor from the gap (see FIG. 1) between the end portion 22 and the rotor 5 can be effectively prevented.
Although the shape of such a convex portion is not limited, as shown in the figure, a wall surface 25a perpendicular to the axial center X of the spool and an inclined surface 25b gradually increasing in diameter toward the front are provided. It is preferable to make the shape provided. According to such a shape, it is possible to make it difficult for the thread to come off, and even if the thread does come off, it can be easily pulled out forward. Moreover, the convex part may be configured to be intermittently formed along the circumferential direction.

FIG. 5 shows a fourth embodiment of the spool.
As described above, the skirt portion 20C gradually decreases in diameter from the front end to the rear end, and in the region where the diameter decreases, the skirt portion 20C has a curved surface without a step from the rear to the front end. If so, the shape of the surface can be modified as appropriate.

It is assumed that the fishing line is looped around the position P of the front end portion 21 of the skirt portion 20C, like the curved surface 43 shown in FIG. The position on the rear end 22 side of the skirt portion 20C at the opposite position on the opposite side of the axis X of the spool is defined by P1, and the positions sequentially transferred to the front side are defined by P2, P3, P4 . . . , P1) is D1, (P, P2) is D2, (P, P3) is D3, and (P, P4) is D4, the curved surface 43 satisfies D4<D1. If the shape is formed so as to be the same and there is no ridge line, the fishing line can be easily pulled out. Then, by making the surface shape D4<D3<D2<D1 so that it gradually becomes shorter (the yarn length becomes shorter) as it moves forward, even if the yarn is entangled, it can be easily removed smoothly. can.

FIG. 6 is a diagram showing a modification of the embodiment described above, and (a) to (c) are diagrams showing examples of shapes of openings formed in the skirt portion of the spool, respectively. This modification shows an example in which an opening is formed in the skirt portion 20C of the spool of the above-described fourth embodiment.
A plurality of openings may be formed in the skirt portion of the spool in order to improve the design and reduce the weight. is preferred. For example, as shown in (a), openings 50 having the same width and extending in the axial direction, or as shown in (b), openings 51 having the same width and extending in the axial direction along the inclined direction. Alternatively, as shown in (c), each opening is formed to be longitudinally elongated in the axial direction, such as an opening 52 having a shape that extends along the axial direction while changing so as to increase in width toward the front. preferably.

With such an opening shape, the resistance to the fishing line is reduced, and the fishing line can be easily pulled out forward.

According to the spinning reel for fishing equipped with the spool as described above, even if the fishing line gets entangled in the skirt portion during actual fishing, the entangled fishing line can be easily removed when the next tackle is released, resulting in tangling or dropping of the line. can be effectively prevented.

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.
In the above configuration, the spinning reel and spool for fishing can be appropriately modified according to the target fish, usage, and the like. For example, a shallow groove type spool or a deep groove type spool may be used. Also, the surface shape of the skirt portion can be appropriately modified as long as it has a curved surface without ridges within a certain range in the front-rear direction.
