Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel provided with a drag mechanism which allows a spool to rotate and delivers a fishing line when an excessive load is applied to the fishing line.

[0002]

2. Description of the Related Art Conventionally, as a fishing reel of this type,
For example, as described in JP-A-10-117645, a spool supported by a spool shaft extending from the reel body and a rotor that rotates coaxially with the spool shaft are provided, and the rotor is handled by a handle on the reel body side. There is known a spinning reel in which a fishing line that engages with a rotor is wound around a spool by rotating the spool. Further, in this reel, when the tension applied to the spool from the fishing line side becomes larger than a predetermined force due to sudden pulling of the fish hooked on the fishing hook, the reel is allowed to rotate with respect to the reel unit, and the fishing line is fed out. It is equipped with a so-called drag mechanism that prevents cutting. That is, the reel is provided with a plurality of friction plates that are in pressure contact with each other between the spool and the spool shaft, and when the tension applied to the fishing line exceeds the pressing force of each friction plate, a braking force due to the friction resistance of each friction plate is applied. However, the spool rotates relative to the spool shaft.

[0003]

However, in the structure using a plurality of friction plates in the drag mechanism as in the conventional reel, the so-called stick-slip, which causes static friction and dynamic friction between the friction plates intermittently, causes There has been a problem that the braking force on the spool becomes unstable and the load of the fishing line suddenly fluctuates when the fishing line is paid out. Further, the conventional friction plates used for reels have a problem in that they are easily deteriorated due to intrusion of frictional heat or seawater and have low durability.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a fishing device which can always provide a stable braking force to the rotation of the spool and which is excellent in durability. The purpose is to provide reels.

[0005]

In order to achieve the above object, the present invention comprises, in claim 1, a structure in which a fishing line is wound around a spool in association with a rotating operation of a handle attached to a reel unit, When tension above a certain level is applied to the fishing line side,
In a fishing reel adapted to allow rotation of a spool while applying a predetermined braking force, a rotating body which rotates integrally with the spool side and a passive member which is arranged on a member side which produces a rotation difference with respect to the spool. A plurality of rollers disposed at predetermined intervals in the circumferential direction of the rotating body between the facing surfaces of the rotating body and the passive body in the axial direction of the rotating body; A holding body that holds the rolling body so as to make a predetermined inclination angle with respect to each of the included planes, and a rotating body and a passive body so that the facing surfaces of the rotating body and the passive body come into contact with each roller at a predetermined contact pressure And a pressing means for pressing in the axial direction. As a result, the rotation of the spool is restricted by the frictional force due to the pressure contact between each roller and the rotating body and the passive body, and when a tension of a predetermined value or more acts on the fishing line side, the rotation of the spool is allowed and the fishing line is paid out. At that time, the spool rotates while applying a braking force due to contact friction between each roller and the rotating body and the passive body. That is, when the rotating body and the passive body rotate relative to each other, each roller rolls while contacting the rotating body and the passive body, but the rolling axis of each roller is relative to the plane including the rotating axis of the rotating body. Since the rollers are inclined by a predetermined angle, each roller rolls while causing sliding friction between the roller and the passive body. At that time, even if static friction occurs at low rotation speed, the rolling of each roller instantly shifts to dynamic friction, so that static friction and dynamic friction rarely occur intermittently.

In this case, according to the second aspect of the present invention, each of the rollers is provided so that its rolling axis is inclined in the same direction with respect to the plane including the rotation axis of the rotating body. Further, claim 3
In the above, each roller is provided such that its rolling axis is alternately inclined by a predetermined number in the opposite direction with respect to the plane including the rotation axis of the rotating body. Further, in claim 4, at least some of the rollers are provided so as to have different inclination angles with respect to the other rollers.

According to a fifth aspect of the present invention, in the fishing reel according to the first, second, third or fourth aspect, the contact pressure between each roller by the pressing means and the rotating body and the passive body can be arbitrarily adjusted. A pressure adjusting means is provided. As a result, in addition to the effect of the first, second, third, or fourth aspect, the magnitude of the braking force applied to the spool is arbitrarily adjusted by changing the contact pressure between each roller and each rotating body.

1 to 3 show a first embodiment of the present invention. FIG. 1 is a partial cross-sectional side view of a spinning reel to which the present invention is applied, and FIG. A sectional view and FIG. 3 are front views of the roller and the cage.

This reel is composed of a reel body 10, a spool 20 around which the fishing line is wound, and a rotor 30 around which the fishing line is wound around the spool 20.

The reel main body 10 has a mounting portion 10a fixed to the fishing rod side at the upper part, and the handle 1 is provided on one side surface side thereof.
1 is rotatably attached. A spool shaft 12 that supports the spool 20 is provided on the front end side of the reel body 10, and the spool shaft 12 reciprocates in the axial direction in association with the rotation of the handle 11. Since a mechanism for reciprocating the spool shaft 12 is well known, illustration and specific description thereof will be omitted. Further, a plurality of grooves 12 extending in the axial direction are formed on a part of the outer peripheral surface of the spool shaft 12.
a are provided at intervals in the circumferential direction, and the tip end side of the spool shaft 12 is formed in a screw shape.

The spool 20 has a fishing line winding portion 20a on its outer peripheral surface.
And a recess 20b is provided on the axially front end face thereof. Further, a plurality of grooves 20c extending in the axial direction are provided on the inner peripheral surface of the recess 20b at intervals in the circumferential direction.
The spool shaft 12 is inserted into the spool 20 so as to penetrate in the axial direction, and a knob 21 is attached to the tip of the spool shaft 12. In this case, the knob 21 has a nut 21a.
Is fixed, and the knob 21 is rotatably engaged with the spool shaft 12 via a nut 21a. Also, the spool 20
In the concave portion 20b, a total of two rotary plates 22 that rotate integrally with the spool 20, a passive plate 23 arranged on the spool shaft 12 side, and a space between the facing surfaces of the rotary plates 22 and the passive plate 23 are arranged. There are provided a plurality of rollers 24 and a total of two cages 25 that hold the rollers 24 so that they can roll. Each rotary plate 22 is formed in an annular shape, and its outer peripheral surface side is engaged with each groove 20c on the spool 20 side so as to be movable in the axial direction. The passive plate 23 is formed in an annular shape, and its inner peripheral surface side is engaged with each groove 12a on the spool shaft 12 side so as to be movable in the axial direction. Each roller 24 includes one rotary plate 22 and one passive plate 2.
3 and between the other rotary plate 22 and the passive plate 23, and are in contact with the facing surfaces of the rotary plate 22 and the passive plate 23, respectively. As shown in FIG. 3, each cage 25 has a plurality of holes 25a for holding the rollers 24 at intervals in the circumferential direction, and the rolling axis A of each roller 24 is the rotation axis of each rotary plate 22. It is held so as to form a predetermined inclination angle θ with respect to a plane C including B (perpendicular to the paper surface). In this case, the rollers 24 are inclined in the same direction. In addition, one rotary plate 22 and the knob 21
A pressing member 26 that presses one of the rotary plates 22 toward the other rotary plate 22 is provided between and.
Is urged toward the rotary plate 22 by a coil spring 27 whose one end is in contact with the knob 21.

The rotor 30 is formed so as to cover the periphery of the spool 20, and is rotated coaxially with the spool shaft 12 by the handle 11 of the reel unit 10.
The rotor 30 and the handle 11 are linked by a gear (not shown), but since this mechanism is well known, a detailed description thereof will be omitted. The rotor 30 has a guide 31 that engages with the fishing line, and the guide 31 is adapted to rotate along with the rotor 30 along the circumferential surface of the spool 20.

In the reel configured as described above, the rotor 30 is rotated by rotating the handle 11 in a predetermined direction, and fishing line (not shown) is wound around the spool 20. At that time, the spool 20 reciprocates in the axial direction as the rotor 30 rotates, and the fishing line is evenly wound in the axial direction of the spool 20.

Further, due to the frictional force due to the pressure contact between each roller 24 of the spool 20 and each rotary plate 22 and passive plate 23,
Although the relative rotation of the spool 20 with respect to the spool shaft 12 is restricted, if a tension of a predetermined value or more acts on the fishing line side due to a sudden pull of a fish caught on a fishing hook or the like, the spool 2
The rotation of 0 is allowed and the fishing line is paid out. At that time, the spool 20 rotates while being applied with a braking force due to contact friction between each roller 24 and each rotary plate 22 and the passive plate 23. That is, when the rotary plates 22 and the passive plate 23 rotate relative to each other, the rollers 24 roll while contacting the rotary plates 22 and the passive plate 23, but the rolling axis A of each roller 24 is the rotary plate. Since each roller 24 is inclined by an angle θ with respect to the plane C including the rotation axis B of the rotation plate 22,
2 and the passive plate 23 roll while causing sliding friction. As a result, even if static friction occurs during low speed rotation, the rolling of each roller 24 instantly shifts to dynamic friction, so that stick-slip in which static friction and dynamic friction intermittently occur is extremely reduced.

When the knob 21 is rotated to increase or decrease the compression amount of the coil spring 27, each roller 2 is moved.
4, the contact pressure between each rotary plate 22 and the passive plate 23 changes, so that the braking force with respect to the rotation of the spool 20 is adjusted according to the amount of rotation of the knob 21.

As described above, according to the fishing reel of this embodiment, the braking force with respect to the rotation of the spool 20 is generated by the sliding friction accompanied by the rolling of each roller 24, so that the rotation is low. However, stick-slip can be extremely reduced, and a stable braking force can always be applied to the rotation of the spool 20. Further, since each roller 24, each rotary plate 22, and the passive plate 23 can be formed of a material having high strength such as metal, deterioration due to intrusion of frictional heat or seawater can be easily performed like a conventional friction plate. It does not occur, and the durability can be improved. Further, in the above configuration, each roller 24
Since the sliding friction of each roller 24 increases as the inclination angle θ of the roller 24 increases, the inclination angle θ of each roller 24 can be arbitrarily set at the time of designing to accommodate a wide range of reels from small to large.

Further, by rotating the knob 21, the spool 2
Since the braking force with respect to 0 rotation can be arbitrarily adjusted, it is possible to appropriately respond to the thickness and strength of the fishing line to be used.

In the above embodiment, the rollers 24 are tilted in the same direction. However, as shown in FIG. 4, the rolling axes A of the rollers 24 are the rotation axes B of the rotary plates 22. May be provided so as to be inclined one by one (or by a predetermined number of two or more) alternately with respect to the plane C including the same angle at the same angle. Further, as shown in FIG.
Is a plane C whose rolling axis A includes the rotational axis B of each rotary plate 22.
However, the rollers 24 having different inclination angles .phi.1, .phi.2, and .phi.3 may be included in the same number, respectively.

The braking force with respect to can be arbitrarily adjusted according to the amount of rotation of the knob 63.

In the second embodiment, the present invention is applied to both bearing reels, but it can also be applied to a single bearing reel in which only one end side of the spool shaft is supported by the reel body. is there.
