Description

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

  The fishing spinning reel has a structure in which a bale for picking up a fishing line is released into a fishing line releasing state. The spool includes a winding body portion around which the fishing line is wound, a front flange portion that defines the amount of fishing line to be wound on the front side, and a rear flange portion (also referred to as a skirt portion) that is defined on the rear side, When the fishing line is discharged, the fishing line is spirally discharged forward while contacting the outer peripheral edge of the front flange portion and receiving resistance.

  The spool is formed of an aluminum alloy, a magnesium alloy, a synthetic resin material, or the like for the purpose of reducing the weight, but at least the outer peripheral edge portion of the front flange portion is subject to wear due to contact at the time of discharging the fishing line and fishing line. In order to prevent scratches, a separate ring-shaped member having wear resistance is attached as disclosed in Patent Documents 1 and 2, for example.

JP-A-2014-1212279 JP-A-2002-204640

The above-described conventional ring-shaped member is joined and fixed so that the fishing line sliding contact guide surface is continuous from the outer peripheral edge portion of the front flange portion toward the upper front.
By the way, the above-mentioned ring-shaped member does not always come into contact with the fishing line wound around the fishing line winding body during the fishing line discharging operation. That is, the fishing line on the rear side (skirt side) from the substantially center of the fishing line winding body swells radially outward and is released forward while being unraveled without any trouble, so that the fishing line to the outer peripheral surface of the ring-shaped member is There is almost no contact and it is extended.
On the other hand, the fishing line near the vicinity of the front flange portion is discharged upward while being guided upward while being in contact with the upper side from the wall surface on the inner side (the fishing line winding body side) of the ring-shaped member. I received resistance, which is a factor that can not extend the flight distance.

  In addition, as a result, the unwinding condition of the fishing line wound around the front flange portion in the unwinding direction is deteriorated, and the fishing line discharged at high speed pushes the previous fishing line on the spool out of the spool. Backlash phenomenon occurs. If backlash actually occurs, it will take time and effort to solve it, damage the fishing line, and it becomes easy for the line to get entangled.Furthermore, there is a problem such as the fishing line cutting into the fishing line and cutting the fishing line. there is a possibility.

  The present invention has been made in view of the above problems, and a spool of a fishing spinning reel and a spinning reel for fishing capable of reducing the resistance given to the fishing line at the front flange portion of the spool when the fishing line is discharged. The purpose is to provide.

In order to achieve the above-mentioned object, a spool of a fishing spinning reel according to the present invention includes a fishing line winding body portion around which a fishing line is wound, a front flange portion that defines a line winding amount of the fishing line winding body portion, and A rear flange portion, and an outer peripheral surface that extends in the front-rear direction is formed at a radially outer end of the front flange portion, and a convex portion whose surface projects radially outward on the front side on the outer peripheral surface. And a gap is formed between the outer peripheral surface and the convex portion so that the discharged fishing line does not come into surface contact .

  The spool having the above-described structure has an outer peripheral surface extending in the front-rear direction formed at the radially outer end of the front flange portion that defines the front side of the fishing line wound around the fishing line winding body, and the front side of the spool has a diameter. By providing a convex part whose surface protrudes outward in the direction, the fishing line released from the fishing line winding body part is separated from the inner wall surface extending along the radial direction of the front flange part that regulates the fishing line. After that, it comes into contact with the convex portion without slidingly contacting the outer peripheral surface extending in the front-rear direction, and comes into sliding contact with the convex portion to move forward. That is, in the outer peripheral region of the front flange portion, the contact area with respect to the fishing line released forward is reduced, so that the release resistance can be reduced as much as possible. As described above, when the fishing line is discharged, the resistance to the fishing line is reduced, so that the reduction of the flight distance is suppressed, and the fishing line in the wound state is stably discharged, so that the occurrence of backlash is suppressed. It becomes possible.

  The present invention is characterized by being a fishing spinning reel equipped with a spool having the front flange portion as described above.

  ADVANTAGE OF THE INVENTION According to this invention, the spool which can reduce the resistance given to a fishing line in the front flange part of a spool at the time of discharging a fishing line, and the fishing spinning reel provided with the spool which has such a function are obtained.

The figure which shows one structural example of the fishing spinning reel which attached the spool which concerns on one Embodiment of this invention. The enlarged view of the spool shown in FIG. It is the figure which expanded the area | region of the front flange part of the spool shown in FIG. 2, and was the figure which showed the sliding state of the fishing line typically. It is a figure contrasted with FIG. 3, and the figure which expanded the area | region of the front flange part of the conventional spool, and was the figure which showed the sliding state of the fishing line typically.

Hereinafter, embodiments of a spool of a fishing spinning reel according to the present invention and a fishing spinning reel equipped with such a spool will be specifically described with reference to the drawings.
FIG. 1 is a diagram showing an example of the structure of a fishing spinning reel equipped with a spool according to an embodiment of the present invention, and FIG. 2 shows a spool mounted on the fishing spinning reel shown in FIG. It is a figure which expands and shows.

First, an outline of the overall configuration of a fishing spinning reel will be described.
In the present invention, the front-back direction means a direction along the axis X of the spool shaft of the spool 10 as shown in FIG. 2, and the reel body side is the rear side. The radial direction means a direction orthogonal to the axis line X. FIG. 2 is a sectional view taken along the axis X of the spool (axial center of the spool shaft), and the spool has the same sectional shape over 360 °.

  A reel main body 1 which constitutes a fishing spinning reel includes a reel leg 1a mounted on a fishing rod, and a rotor 5 rotatably supported in front of the reel leg 1a and a front and rear in synchronization with a rotational movement of the rotor 5. A spool 10 is provided which is movably supported and around which fishing line is wound.

  A handle shaft 7a is rotatably supported in the reel body 1, and a handle 7 is attached to a protruding end portion of the handle shaft 7a. A winding drive mechanism is engaged with the handle shaft 7a. As is well known, the winding drive mechanism is attached to a handle shaft and has a drive gear (drive gear) 8 having internal teeth formed thereon, which meshes with the drive gear 8 and extends in a direction orthogonal to the handle shaft 5a. , And a pinion gear in which a hollow portion extending in the axial direction is formed.

  A spool shaft that rotatably supports the spool 10 is inserted into the pinion gear so as to be axially movable back and forth. A known oscillating mechanism is engaged with the rear side of the spool shaft, and when the handle 7 is rotated, the spool 10 is reciprocated back and forth through the oscillating mechanism and the spool shaft. The rotor 5 is fixed to the pinion gear by tightening a rotor nut on the front side of the pinion gear. As a result, when the handle 7 is wound up, the rotor 5 is rotated, the spool 3 is reciprocated back and forth in synchronization with this rotation, and the fishing line is passed through the fishing line guide device 5A that rotates with the rotor 5. It is wound around the spool 10.

Next, the configuration of the spool 10 described above will be described.
The spool 10 is made of a metal having a low specific gravity such as aluminum, an aluminum alloy, a magnesium alloy, or a synthetic resin material, and has a fishing line winding body 20 around which fishing line is wound and a fishing line winding body 20. Has a front flange portion 30 and a rear flange portion (skirt portion) 40 that define the amount of bobbin winding in the front-rear direction. The fishing line S is wound on the surface of the fishing line winding body 20 as shown in FIG. In this case, as described above, when the fishing line is wound around the spool 10, the spool 10 is reciprocally driven in the front-rear direction by the rotation operation of the handle 7 in the winding direction, around which the fishing line guide along with the rotor 5. Since the device 5A rotates, the fishing line S is wound around the fishing line winding body portion 20 substantially uniformly. FIG. 2 shows a state in which the fishing line S is wound substantially evenly around the fishing line winding body portion 20, and the rotation state is restricted by the front flange portion 30 and the rear flange portion 40 on both sides in the front-rear direction. Therefore, the winding amount of the fishing line is determined by the radial height of each flange portion (the line SW indicated by the dotted line is the maximum winding amount). In a fishing spinning reel such as a surf type which casts long-distance tricks, as shown in FIG. 2, the front flange portion 30 and the rear flange portion 40 are low in height and the longitudinal direction of the fishing line winding body portion 20 is long. , So-called shallow groove type spool.

  A ring-shaped member 31, which is separate from the spool, is attached to the front flange portion 30. The ring-shaped member 31 is for preventing the spool portion from being worn due to the contact with the discharged fishing line and preventing the fishing line from being scratched. The ring-shaped member 31 is made of a hard metal such as a stainless alloy or a titanium alloy, or aluminum or aluminum. It is made of alloy, ceramics, or the like.

  Here, the configuration of the front flange portion 30 and the ring-shaped member attached to the front flange portion will be described with reference to FIG.

  The ring-shaped member 31 is attached to the front side of the outer peripheral surface 32 of the front flange portion 30. The outer peripheral surface 32 is provided at the radially outer end of the front flange portion 30 and has a constant length along the front-rear direction. That is, the outer peripheral surface 32 constitutes the flange portion 30, and is directed toward the front side at the upper end position of the inner wall surface 32a of the front flange portion against which the fishing line wound on the fishing line winding body 20 abuts. It is a ring-shaped annular surface that extends. Therefore, an inflection point P1 where the surface of the inner wall surface 32a changes exists between the outer peripheral surface 32 and the inner wall surface 32a. The inflection point P1 is a position where the fishing line in contact with the inner wall surface 32a moves away when the fishing line is discharged.

  The outer peripheral surface 32 can be configured by, for example, a surface parallel to the axis X, a surface inclined with respect to the axis X, or a curved surface along the axis X, but the outer surface of the ring-shaped member 31 ( Any material may be used as long as it creates a gap R between the convex portion 31b). In the present embodiment, as shown in FIG. 3, it is configured by a substantially flat surface that gradually rises toward the front side along the axis X (plane X1 parallel to the axis X).

  The ring-shaped member 31 attached to the outer peripheral surface 32 includes an annular protrusion 31a formed at an intermediate portion on the inner surface side and a convex portion (surface) 31b formed on the outer surface side and having a bulged surface. ing. In this ring-shaped member 31, the annular projection 31a is applied to the front end edge 32b of the outer peripheral surface 32, the holding member 35 is fitted from the front side, and the female screw portion 35b formed on the cylindrical portion 35a of the holding member is wound with a fishing line. By being screwed into the male screw portion 20b formed on the annular main body 20a of the rotating body portion 20, the front body member 32 is sandwiched and fixed between the front end edge 32b and the holding member 35.

  The surface of the convex portion (surface) 31b of the ring-shaped member 31 has a cross-sectional shape that rises as it moves forward and has a maximum bulge position P2. That is, the convex portion (surface) 31b that causes the gap R in the present embodiment bulges while curving upward from the bulging base end position P3 to the maximum bulging position P2 with respect to the surface of the outer peripheral surface 32. The ring-shaped member 31 is attached to the front flange portion of the spool.

  By attaching the ring-shaped member 31 having the above-described configuration to the front flange portion 30, it is discharged between the inflection point P1 and the bulging base end position P3, as described below. The gap R where the fishing line does not come into surface contact is formed. Specifically, when the bail provided with the fishing line guide device 5A is rotated to the fishing line discharging position to release the engagement with the fishing line and the fishing line is discharged by casting the fishing rod, the fishing line winding body portion 20. The fishing line wound around is released in a spiral shape while being unwound. As described above, the fishing line near the vicinity of the front flange portion 30 is discharged forward while being guided upward while being in contact with the surface of the ring-shaped member, and therefore receives contact resistance, which reduces the flight distance. It is a factor. In the present invention, when the ring-shaped member 31 is attached to the front flange portion 30, the outer peripheral surface 32 is provided so that the above-described gap R is formed, so that the contact resistance to the fishing line is reduced as much as possible. It is configured to do.

  Hereinafter, this operation will be described while comparing FIG. 3 showing the configuration of the present embodiment and FIG. 4 showing the configuration in which the conventional ring-shaped member is attached. Since the fishing line is released while unwinding the wound state around the fishing line winding body portion 20, the fishing line moves forward while contacting with the ring-shaped member while rotating (raising spirally). 3, 4A and 4B, in order to make the behavior of the fishing line easy to understand, the transition state of the fishing line is shown in one cross section.

  As shown in FIG. 3, in the present embodiment, the fishing line S1 that has left the inner wall surface 32a (inflection point P1) of the front flange portion 30 moves forward without receiving frictional resistance in the gap R portion, The convex portion 31b of the ring-shaped member 31 is contacted (S2), and the surface thereof is lifted and separated at the position of the maximum bulging portion P2 (S3).

  On the other hand, in the conventional ring-shaped member 31A shown in FIG. 4, the fishing line S1 that has left the inner wall surface 32a of the flange portion 30A immediately contacts the surface 31b '(S2) and moves upward while moving to the maximum. Since they are separated at the bulging portion P2, compared to the configuration shown in FIG. 3, the frictional resistance to the fishing line from contact (S2) to separation (S3) becomes large, and the flight distance of the tackle does not extend.

  That is, in the present invention, the outer peripheral surface 32 extending in the front-rear direction is formed at the radially outer end of the front flange portion 30, and the convex portion (ring-shaped portion) whose surface projects radially outward is formed on the front side of this portion. By providing the convex portion 31b) of the member 31, it is possible to reduce a region where the fishing line comes into contact at the time of discharging, thereby reducing the contact resistance with respect to the fishing line and extending the flight distance of the tackle.

  Further, since the contact resistance with respect to the fishing line is reduced, the unwinding state of the fishing line wound near the front flange portion in the unwinding direction becomes good, and the fishing line discharged at high speed is Since it is possible to suppress the repelling of the fishing line from the spool (backlash phenomenon), it is possible to prevent the fishing line from being damaged and to prevent the fishing line from being entangled.

Next, a more preferable configuration of the ring-shaped member 31 in the configuration shown in FIG. 3 will be described.
As described above, at the upper end position of the inner wall surface 32a of the flange portion 30, the inflection point bent forward is P1, the maximum bulge position of the convex portion 31b is P2, and the convex portion 31b is bulged with respect to the outer peripheral surface 32. When the base end position is P3, the front-rear length between P1 and P2 is L1, and the front-rear length between P2 and P3 is L2, L2 is preferably in the range of 45 to 75% of L1. .

  The L2 corresponds to the approximate thickness of the ring-shaped member 31 in the front-rear direction, and if it is too thin, the fishing line may be damaged. Therefore, at least 20% or more of the L2 is secured relative to the L1. It is preferable that the gap R is wide, but it is not preferable in terms of strength. On the contrary, if the L2 is too thick, the sufficient gap R cannot be formed. Therefore, it is preferably at least 75% or less with respect to the L1. Even if the fishing line having a large diameter is wound around the spool 10 to a certain extent, it is possible to secure the gap R that effectively prevents the fishing line from coming into contact with each other as long as it is 75% or less.

  Further, by reducing the radial height of the ring-shaped member 31, the discharge angle θ can be made gentle and the contact resistance to the fishing line can be reduced as much as possible. Specifically, when the radial height at the maximum bulge position P2 (radial height between the P2 and P3) is H, the length of the ring-shaped member 31 in the substantially front-back direction (between P2 and P3). It is preferable to set (L2 ≧ H) below the length L2) in the front-rear direction. Such a dimensional relationship makes it possible to stabilize the fixed state because the ring-shaped member is flat, and to suppress the amount of bulge to loosen the discharge angle θ, effectively reducing the contact resistance to the fishing line. Can be reduced.

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 variously modified.
In the structure described above, the attachment structure of the ring-shaped member 31 can be appropriately modified. In addition, although the convex portion 31b in the present embodiment is formed of a curved surface, it may be a flat surface that gradually rises toward the front, or a concave shape that gradually rises, or these shapes. It may be a composite structure. That is, in the present invention, if the outer peripheral surface 32 extending in the front-rear direction is formed at the radially outer end of the front flange portion 30, the cross-sectional shape of the ring-shaped member 31 attached to the front side thereof is appropriately determined. It can be transformed.

  Further, in the above-described configuration, the ring-shaped member 31 is configured as a separate body from the spool, but may be integrally formed with the spool (for example, integrally formed of aluminum, aluminum alloy, or synthetic resin material). Furthermore, the spinning reel for fishing and the spool can be appropriately modified in shape and material according to the target fish, fishing method, etc., and may be configured as a deep groove type spool, for example. .
