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 restricting and controlling the rotation direction of a rotor in a spinning reel.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 54-14128
As disclosed in Japanese Patent Laid-Open Publication No. 5 (1999) -2005, a bearing that rotates in only one direction by the movement locking action of a bearing member is provided on a shaft cylinder portion of a rotor of a spinning reel, and a reciprocating pivot is provided at the front of the bearing. A locking piece that protrudes into the guide groove of the bearing member protrudes from the provided regulating plate, and the housing prevents a reverse rotation of the fishing spinning reel that supports an operating rod that rotates the regulating plate. Devices are known.

According to this spinning reel reverse rotation prevention device, when the operating rod is rotated to rotate the regulating plate by the projection of the cam and the locking piece is moved to the end of the guide slot, the shaft cylinder is rotated. When the portion is rotated in the normal rotation direction, the bearing member becomes idle in the guide slot, thereby rotating the shaft cylinder portion. In the reverse rotation direction, the bearing member prevents the rotation of the shaft cylinder portion, thereby preventing the rotor from rotating in the reverse direction.

However, since a method is employed in which the bearing member is switched to the tightened or released state by moving the small locking piece provided on the regulating plate, the positional relationship between the locking piece and the bearing member is reduced. It 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. In this device, an annular holding body for holding the rolling member is provided separately so that the rolling member can be operated stably.

However, in this conventional reverse rotation preventing device, a switching lever for controlling the operation of the annular holding member is provided integrally or integrally to restrict the amount of rotation of the annular holding member. In order to apply the anti-reverse device to the designed reel, all parts including the annular holder must be replaced. Therefore, there is no degree of freedom when applying this reverse rotation prevention device to another reel. In addition, when it is desired to change the mounting position (angle) of the clutch lever, it is necessary to change all the parts including the annular holder. Such a structure in which a plurality of parts are integrated, that is, a structure in which the annular holder and the switching lever are integrated, lacks versatility and is extremely inefficient in terms of manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a fishing reel reverse rotation preventing device according to the present invention will be described below with reference to the drawings. 1 and 2 show a configuration example of a spinning reel according to this embodiment. In the figure, 1 is a reel body, 2 is a handle, 3 is a handle arm, 4 is a drive gear rotated by the handle 2, 5 is a pinion gear that meshes with the drive gear 4, 6 is a main shaft, and the main shaft 6 is a pinion gear 5 to support a plurality of components described below, including the same. A rotor 7 is connected and fixed to the shaft end of the pinion gear 5, and the rotation of the handle 2 causes the rotor 7 to rotate forward and backward.

Reference numeral 8 denotes a gear fixed to the drive gear 4, and 9 denotes a gear that meshes with the gear 8. The rotation of the gear 9 causes the slider 10 engaged with the projection 9a to slide back and forth (in FIG. 2, the front and rear directions are indicated by arrows F and R, respectively). The main shaft 6 is connected to the slider 10. A spool 11 is supported at the front end of the main shaft 6, and the slide 11 also causes the spool 11 to reciprocate back and forth by a predetermined stroke as the slider 10 slides.

As described above, the spinning reel is provided with a rotation mechanism for rotating the rotor 7 and a slide mechanism for sliding the spool 11. According to this basic configuration, the rotation of the handle 2 causes the rotor 7 to rotate forward and reverse via the drive gear 4 and the pinion gear 5, and interlocks with the rotation of the rotor 7.
Spool 11 via gears 8, 9 and slider 10
Slide back and forth. By this rotation / sliding operation, the fishing line can be wound up or wound out around the winding portion 11a of the spool 11 via the line roller 12.

Here, the rotation of the rotor 7 can be selectively restricted by clutch means attached to the rotor rotation shaft, that is, the pinion gear 5. That is, in this example, as shown in FIG.
A bearing 13 is externally fitted on the rotor 7 side, and a clutch means 14 is connected to the bearing 13. The operation of the clutch means 14 is controlled by a clutch lever 15 located between the bearing 13 and the clutch means 14.

A bearing holder 19 is fitted around the bearing 13 mounted on the shaft of the pinion gear 5,
A bearing retainer 20 for fixing the bearing 13
Are fastened in place to the reel body 1 by screws 21 or the like .

As will be described later, the clutch lever 15 is provided with the clutch means 14, specifically, a clutch retainer 24.
As shown in FIGS. 4 and 5, a spring 16 is stretched between the end of the clutch lever 15 and the reel body 1. The elasticity of the spring 16 urges the clutch means 14 in a predetermined direction. The end of the clutch lever 15 has a check cam 17 of the operating rod 17.
a is engaged, and the clutch lever 15 can be driven from outside the reel body 1 by the operation lever 18 attached to the end of the operation rod 17 (FIG. 1,
(See FIG. 2).

The clutch means 14 and the clutch lever 15 are interconnected as shown in FIG. 6 or FIG.
Here, as shown in FIGS. 8 and 9, the clutch means 14 is connected to the inner ring 13a of the bearing 13 and fixed to the rotor rotating shaft (that is, the pinion gear 5).
2, a retainer 24 (see FIG. 11) for holding a plurality of rolling rollers 23 around the sleeve 22, and an outer frame body 25 for forming a wedge-shaped accommodation portion 25a between the sleeve 22 and the outer peripheral surface.
(See FIG. 10).

The rolling roller 23 is formed in an elongated cylindrical shape, and is held by a holding portion 24a (FIG. 11) of a retainer 24. The retainer 24 has an uneven portion 24b at its end (FIG. 9). As shown in FIGS. 5 to 7, the clutch lever 15 has an uneven portion 15a which fits into the uneven portion 24b of the retainer 24. The uneven portion 15a of the clutch lever and the uneven portion 24b of the retainer fit. By combining
The clutch lever 15 and the retainer 24 are mutually connected. The clutch lever 15 and the retainer 24 are configured separately, but each has an uneven portion 15a having the same dimensions.
And the same number of uneven portions 24b.

As shown in FIG. 10, the inner peripheral surface of the outer frame 25 is formed so that the diameter thereof is gradually reduced at regular intervals to provide a wedge-shaped accommodation portion 25a. The rolling roller 23 rotates freely in the large diameter portion of the wedge-shaped accommodation portion 25a, and bites into the wedge-shaped accommodation portion 25a of the outer frame 25 in the small diameter portion.

In the above configuration, as described above, through the rotation mechanism of the rotor 7 and the slide mechanism of the spool 11,
By performing rotation (winding function) and sliding operation (oscillating function), the fishing line is wound around the winding portion 11a of the spool 11 via the line roller 12,
Or it can be paid out. When the rotor 7 is rotated, the clutch means 14 can selectively restrict particularly the reverse rotation of the rotor 7.

Now, when the clutch means 14 is operated to restrict the reverse rotation of the rotor 7, the clutch lever 15 is moved counterclockwise as shown in FIG. 4 or FIG. (Angle -θ). As a result, as shown in FIG. 7A, the rolling roller 23 held by the holding portion 24a of the retainer 24 moves to the small-diameter portion side of the wedge-shaped accommodation portion 25a of the outer frame 25. By operating the clutch lever 15 in this manner, when the rotor 7 rotates in the reverse direction, the rolling roller 23 bites into the wedge-shaped accommodation portion 25a and regulates the reverse rotation.

As described above, the operation of the clutch means 14 (O
At the time of N), the clutch lever 15 is urged by the spring 16 in the direction in which the rolling roller 23 strengthens the engagement. In addition, the clutch roller 14 is not extremely strongly pressed by the clutch lever 15 toward the small diameter portion side of the rolling roller, but is pressed by the spring force. Therefore, the operation of the clutch means 14 (O
N) At the time, when the rotor 7 is going to rotate in the reverse direction,
The rolling roller bites between the wedge-shaped accommodating portion 25a and the sleeve 22 instantaneously by the spring force to regulate the reverse rotation. When the clutch means 14 is ON, the spring 16 has a strength that does not restrict the rotation in the normal rotation direction, and operates smoothly.

On the other hand, when the clutch means 14 is not operated, that is, when the reverse rotation of the rotor 7 is not restricted, the operation lever 18
By operating the clutch lever 15, the clutch lever 15 is driven in the clockwise direction (the angle θ) as shown in FIG. 4 or FIG. As a result, as shown in FIG. 7B, the rolling roller 23 held by the holding portion 24a of the retainer 24 moves to the large-diameter portion side of the wedge-shaped accommodation portion 25a of the outer frame 25. At this time, the rolling roller 23 is
It becomes free within a and does not regulate the rotation in both the forward and reverse directions.

By the way, as described above, the clutch lever 15 and the retainer 24 are formed separately, and are connected to each other by fitting the concave and convex portions 15a and 24b. When the clutch means 14 is ON, the clutch lever 15 is appropriately driven by operating the operation lever 18, and
Thus, the reverse rotation of the rotor 7 can be reliably prevented in the reverse rotation prevention mode.

Further, since the clutch lever 15 and the retainer 24 are provided separately, it is possible to effectively cope with a change of the model only by replacing the clutch lever 15 while sharing the retainer 24. For example, the reverse rotation preventing device can be applied to a reel having a larger design by using a clutch lever 15 having a longer length. Further, the degree of freedom in assembling these components can be increased, and the assemblability can be greatly improved. That is, when assembling the clutch lever 15 to the retainer 24, for example, as shown by a two-dot chain line in FIG. Alternatively, it can be arranged downward. Thereby, the arrangement of the operation lever 18 and the operation rod 17 can be freely set as needed without changing the shape and the like of the outer frame 25.

Although the present invention has been described above, the present invention is not limited to the embodiment, and it goes without saying that various other modifications are possible without departing from the essence of the present invention. For example, the number and the like of the concave and convex portions 15a and the concave and convex portions 24b provided on the clutch lever 15 and the retainer 24 can be appropriately set as needed.
