DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reverse rotation preventing device for a reel, and more particularly to a reverse rotation preventing device for regulating and controlling the rotation direction of a rotor in a spinning reel.

[0002]

2. Description of the Related Art In fishing, usually, when winding up a fishing line, a reel provided with a reverse rotation preventing function is always used. For example, a spinning reel disclosed in Japanese Patent Application Laid-Open No. 54-141285 discloses a reverse rotation preventing device.
In this device, a bearing that rotates in only one direction by a movement locking action of a bearing member is mounted on a shaft cylinder portion of a rotor of a spinning reel, and a locking piece located in a guide groove hole of the bearing member of the bearing is mounted. A protruding regulating plate is provided so as to be reciprocally rotatable, and is operated by an operating rod supported on a housing.

According to the spinning reel reverse rotation preventing device, when the operating rod is rotated, the regulating plate is rotated by the projection of the cam, and the locking piece is moved to the end of the guide slot, the shaft cylinder portion is rotated. During the rotation in the forward rotation direction, the bearing member enters the idle rotation state in the guide slot, thereby rotating the shaft cylinder portion. In the reverse rotation of the barrel, the bearing member prevents the barrel from rotating,
This is to prevent the rotation of the rotor from reversing. Therefore, the fishing line operation can be efficiently performed by arbitrarily switching the winding, unwinding, and reverse rotation preventing operations of the fishing line.

However, since a method in which the bearing member is switched to the tightened or released state by the movement of the small locking piece provided on the regulating plate is adopted, the positional relationship between the locking piece and the bearing member is reduced. May not be stable and not always satisfactory.

Therefore, a reverse rotation prevention device as disclosed in Japanese Patent Application Laid-Open No. 6-225573 has been developed. This device is provided with a separate annular holding body for holding the rolling member so that the rolling member performs a stable operation, and is useful as a device overcoming the above-mentioned drawbacks.

In this conventional reverse rotation preventing device, a switching lever (rotating operating member) for controlling the operation of the annular holder is provided.
Are provided integrally or integrally with the annular holder, and each of the guide slots of the annular holder is provided so that each rolling member bites between the annular outer frame and the collar, i.e., performs a wedge action, and It is possible to switch so as to be released.

However, in this conventional reverse rotation preventing device, the switching lever and the annular holding member are integrally formed, and the operation of the switching lever causes the rolling member to move at one end via the annular holding member. . in this way,
Since the rolling member is moved in two stages indirectly via the annular holding member, for example, when it is desired to switch the clutch immediately, play occurs in the switching operation, and it is not always possible to switch the clutch instantaneously. Conventionally, when the switching lever is operated, the annular holding member moves, and the rolling member that is fitted in the guide slot moves.This is a dynamic transmission mechanism. There is no instantaneous clutch switching. That is, the switching operation with a sharp effect cannot be performed.

In addition to the above structural problems, there is also a problem in assembling the entire clutch. That is,
In the conventional anti-reverse device, when assembling the clutch, the annular holding body is extrapolated to the collar, but if even one of several rolling members is not completely fitted in the guide slot, The annular outer frame cannot be extrapolated with the support of the rolling members. Further, in the conventional reverse rotation prevention device, the number of parts such as the annular holding body, the annular outer frame, the rolling member, the collar, and the rotating operation member is large, and the structure around the clutch is complicated. Therefore, the number of assembling steps is increased, and the cost is increased.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a reverse rotation prevention device according to the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of a spinning reel according to this embodiment. In the figure, 1 is a reel body, 2
Is a drive gear that rotates by operating a handle (not shown), 3 is a rotor shaft that meshes with the drive gear 2,
That is, the pinion gear 4 is a main shaft, and the main shaft 4 supports a plurality of components described below, including the pinion gear 3. A rotor 5 is connected and fixed to the shaft end of the pinion gear 3, and the rotor 5 is rotated forward and reverse by rotating a handle (not shown).

Reference numeral 6 denotes a gear fixed to the drive gear 2, and 7 denotes a gear that meshes with the gear 6. The rotation of the gear 7 causes the slider 8 engaging with the protrusion 7a to move back and forth (FIG. 1).
, The front and rear directions are indicated by arrows F and R, respectively). The main shaft 4 is connected to the slider 8. A spool 9 is supported at the front end of the main shaft 4, and the slide 9 also causes the spool 9 to reciprocate back and forth by a predetermined stroke.

As described above, the rotation mechanism for rotating the rotor 5 and the slide mechanism for sliding the spool 9 are provided. According to this basic configuration, the rotor 5 is rotated forward and reverse via the drive gear 2 and the pinion gear 3 by rotating the handle, and the gears 6 and 7 and the slider 8 and the like are interlocked with the rotation of the rotor 5. The spool 9 is slid back and forth through the intermediary. By this rotation / sliding operation, the fishing line can be wound up or wound out around the winding portion 9a of the spool 9 via the line roller 10.

Here, the rotation of the rotor 5 can be selectively restricted by clutch means attached to the rotor rotation shaft, that is, the pinion gear 3. That is, in this example, as shown in FIG.
The bearing 11 is externally fitted to the rotor 5 side, and the clutch means 12 is connected to the bearing 11. The operation of the clutch means 12 is controlled by an operation lever 13 interposed between the bearing 11 and the clutch means 12.

The operating lever 13 is connected to the clutch means 12 as described later. A spring 14 is stretched between the end of the operating lever 13 and the reel body 1 as shown in FIG. Due to the elasticity of the spring 14, the clutch means 12, more specifically, the operating roller 13 is moved by a rolling roller 22 described later into a sleeve
It is always given in the direction of biting 0 and strengthening the engagement. The operating rod 1 is provided in the cam hole 13a at the end of the operating lever 13.
5 are engaged with each other, and the operating lever 13 can be driven from the outside of the reel body 1 by the operating lever 16 attached to the end of the operating rod 15 (FIG. 1). ).

As shown in FIGS. 1 and 2, a bearing holder 17 is fitted around the bearing 11 mounted on the shaft of the pinion gear 3, and a bearing retainer 18 for fixing the bearing 11 is screwed. 19 fastens the reel body 1 in place.

Here, the clutch means 12 and the operating lever 1
3 are interconnected as shown in FIG. In the present embodiment, the clutch means 12 includes an outer frame body 21 that forms a wedge-shaped accommodation portion 21a between the sleeve 20 fixed to the pinion gear 3 that is the rotor rotation shaft and the outer peripheral surface of the sleeve 20.
A plurality of rolling rollers 22 supported by the outer frame body 21;
One end 22a of the rolling roller 22 protruding from the outer frame 21
And an operating lever 13 for inserting and holding the same.

In the present invention, the rolling roller 22 is tilted by rotating the operating lever 13 so that the rolling roller 22 is engaged or released between the sleeve 20 and the wedge-shaped receiving portion 21a. The above-mentioned operating lever 13 is urged by the above-mentioned spring 14 in a direction in which the rolling roller 22 is strengthened in the wedge-shaped accommodation portion 21a.

The rolling roller 22 is formed in an elongated cylindrical shape, and one end 22b is formed in a spherical shape. And it is accommodated in the wedge-shaped accommodation part 21a of the outer frame 21, specifically between the sleeve 20 and the wedge-shaped accommodation part 21a. In this example, the wedge-shaped housing portion 21a of the outer frame body 21 is arranged so as to divide the circumference into six parts, but differs depending on the number of rolling rollers 22 used.

The outer frame 21 is formed with a reduced diameter bottom portion 21b. The bottom portion 21b supports the end 22b of the rolling roller 22 on the small diameter side of each wedge-shaped accommodating portion 21a. Is provided. Since the end 22b of the rolling roller 22 is formed in a spherical shape as described above, the concave portion H of the bottom 21b is also formed in a spherical shape so as to correspond to the spherical surface. Therefore, the end 22b of the rolling roller 22
Can be freely inclined by being supported by the concave portion H at the bottom of the outer frame 21.

On the other hand, the operating lever 13 has a plurality of (six in this example) engaging portions 13b corresponding to the bottom 21b of the outer frame 21 as shown in FIG. The other end 22a of the rolling roller 22 is inserted into the engagement portion 13b.

As will be described later, when the end portion 22a of the rolling roller 22 is positioned on the side of the small diameter portion of the wedge-shaped housing portion 21a by operating the operating lever 13, the end portion 22a is parallel to the axial direction of the sleeve, and Bite. Further, when it is located on the large diameter portion side, the sleeve is inclined with respect to the axial direction of the sleeve, and can freely rotate in the wedge-shaped accommodation portion 21a.

In the above configuration, the fishing line is rotated and slid by the rotation mechanism of the rotor 5 and the slide mechanism of the spool 9 as described above, so that the fishing line is wound on the spool 9 via the line roller 10. 9a can be wound up or unwound. Rotor 5
Can be selectively restricted by the clutch means 12 particularly in the reverse rotation of the rotor 5.

Now, it is assumed that the clutch 12 is operated to restrict the reverse rotation of the rotor 5. Operation lever 16
Is operated to drive the operating lever 13 counterclockwise from the neutral position (not shown) as shown in FIG. As a result, the engaging portion 13b of the operating lever 13 coincides with the position on the extension of the bottom portion 21b of the outer frame 21, and the rolling roller 22 moves along the axial direction as shown in the small-diameter portion of the wedge-shaped accommodation portion 21a. Are arranged in parallel.

By arranging the roller at the small diameter portion in this manner, the rolling roller 22 can bite the sleeve 20. That is, when the rotor 5 rotates in the reverse direction, the rolling roller 22 bites into the wedge-shaped housing portion 21a and the sleeve 20 to restrict the reverse rotation.

In the present invention, by operating the operating lever 13 as described above, the rolling roller 2 is directly driven.
Since the clutch means 12 is operated (ON) by moving the lever 2, the transmission of the force at the time of switching is direct. Therefore, the rotor 5 is immediately prevented from reverse rotation. Needless to say, when the clutch means 12 is ON, it operates smoothly without restricting rotation in the normal rotation direction.

On the other hand, it is assumed that the clutch means 12 is not operated, that is, the reverse rotation of the rotor 5 is not restricted (OFF state). As shown in FIG. 4, the operating lever 16 is moved to move the operating lever 13 clockwise from the neutral position (not shown) via the operating rod 15 in the opposite direction. As a result, the engaging portion 13b of the operating lever 13 moves toward the large-diameter portion side of the wedge-shaped accommodation portion 21a of the outer frame 21 so as to be disengaged from the extension of the bottom 21b of the corresponding outer frame 21.
At this time, the rolling roller 22 is moved to the wedge-shaped
It is arranged at an angle in a and becomes free. Needless to say, when the motor is turned off, the rotation is not restricted in both the forward and reverse rotation directions of the rotor.

By the way, the above-mentioned clutch means 12 is turned on.
At this time, the rolling roller 22 is attached to the wedge-shaped accommodation portion 21a of the outer frame body 21.
Bites into the small diameter part by line contact at. Unlike the related art, the rolling roller 22 can be set long in structure, so that the contact length is increased, the biting effect is increased, and the strength of the non-return can be increased. In the production of the reel of the present invention,
Assembly around the clutch becomes extremely simple. That is, since the rolling roller 22 can be inserted from the engaging portion 13b of the operation lever 13 and can be mounted on the wedge-shaped receiving portion 21a of the outer frame 21, the assembling work is simple and easy. Furthermore, since the rolling roller 22 can be directly accommodated in the wedge-shaped accommodation portion 21a of the outer frame body 21 without using a so-called retainer or the like, the assembling becomes easier.

Although the present invention has been described above, the present invention is not limited only to the embodiment, and it goes without saying that various other modifications can be made without departing from the essence of the present invention. For example, the number of the rolling rollers or the number of the wedge-shaped housing portions 21a for housing the rolling rollers is not limited to the above-described embodiment, and can be appropriately selected.

[0040]

As described above, according to the present invention, in this kind of spinning reel, particularly, the rolling roller is directly moved by the operating lever, that is, the operating lever and the rolling roller are directly connected. In addition, instantaneous and accurate clutch switching operation can be guaranteed. In addition, the assembling workability can be greatly improved, the manufacturing efficiency can be improved, and the number of components can be substantially reduced, the structure can be simplified, and the cost can be reduced.
