[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reverse rotation preventing device for regulating and controlling a 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 (1993) -2005, a bearing that rotates in only one direction due to 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 reversing rotation of a fishing spinning reel in which a locking plate projecting into a guide groove hole of the bearing member is projected from a regulating plate provided on the bearing member, and an operating rod for rotating the regulating plate is supported on a housing. Prevention 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 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, Japanese Patent Application Laid-Open No.
A reverse rotation prevention device as disclosed in Japanese Patent Application Laid-Open Publication No. H10-209,873 has been developed. This device is provided with a separate annular holding body for holding the rolling member so as to stably operate the rolling member, and is useful as a device overcoming the above-mentioned disadvantages.

[0006]

However, in the conventional reverse rotation preventing device, the rolling member is moved via the annular holding member by operating the switching lever. As described above, since the rolling member is indirectly moved via the annular holding member, even if the clutch is to be switched immediately, for example, there is play in the switching operation and the clutch is necessarily instantaneously disengaged. Not replace.

That is, when the switching lever is moved, the annular holding member moves, and the rolling member fitted in the guide slot moves. This is a force transmission mechanism. This does not result in a typical clutch switch. There is no so-called sharp effect. In addition to the above structural problems, there is a problem in assembling the entire clutch.

That is, in the conventional reverse rotation preventing device, when assembling the clutch, the annular holding body is attached to the collar, and the annular outer frame is externally inserted in a state where the rolling members are fitted into the respective guide slots. However, if even one of the several rolling members is not completely fitted in the guide slot, the rolling member hinders the external outer frame from being inserted. The recent assembly is very cumbersome.

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 attached to the front end of the main shaft 4, and the reciprocating movement of the slider 8 causes the spool 9 to reciprocate a predetermined stroke back and forth.

As described above, the fishing reel basically has two mechanisms, a rotating mechanism for rotating the rotor 5 and a sliding mechanism for sliding the spool 9. According to this basic mechanism, the rotor 5 is rotated forward and reverse through the drive gear 2 and the pinion gear 3 by rotating the handle, and the gears 6 and 7 and the slider 8 are linked to the rotation of the rotor 5. The spool 9 attached to the front end of the main shaft 4 is slid back and forth. 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 clutch 5, which is interposed between the reel body and the rotor rotation shaft (ie, the pinion gear 3), is configured to selectively restrict the rotation of the rotor 5, particularly the reverse rotation. That is, in this example, as shown in FIG. 2, the bearing 11 is fitted on the rotor side of the pinion gear 3, and the clutch means 12 is connected to the bearing 11.

The operating lever 13 interposed between the bearing 11 and the clutch means 12 causes
The operation of the clutch means 12 is controlled.
A bearing holder 17 is fitted around the bearing 11 as shown in FIGS. 1 and 2, and a bearing retainer 18 for fixing the bearing 11 is fastened in place to the reel body by screws 19 or the like. The operating lever 13 is connected to a positioning frame 22 of the clutch means 12 via a rolling roller 21 as described later, and a spring 14 is provided between the end of the operating lever 13 and the reel body 1 as shown in FIG. Is stretched.

Due to the elasticity of the spring 14, the clutch means 12, more specifically the operating lever 13, is constantly urged in a direction in which a rolling roller 21, which will be described later, bites into the sleeve 20 in the wedge-shaped storage portion 23a to strengthen the engagement. You. A check cam 15a of the operating rod 15 is engaged with a cam hole 13a at an end of the operating lever 13. When the operating lever 16 attached to the end of the operating rod 15 is moved, the reel body is moved. 1, the operating lever 13 can be driven from outside (FIG. 1).

Here, the clutch means 12 and the operating lever 1
3 are interconnected as shown in FIG. The clutch means 12 in the present embodiment includes a sleeve 20 fixed to a pinion gear 3 that is a rotor rotation shaft,
0 and a positioning frame 22 for positioning the plurality of rolling rollers 21 around
2 is rotatable), an operating lever 13 for inserting and holding a part of the rolling roller 21 protruding from the positioning frame 22.
And an outer frame body 23 that forms a wedge-shaped accommodating portion 23 a between the outer peripheral surface of the sleeve 20.

The rolling roller 21 is formed in an elongated cylindrical shape, and is arranged and accommodated in the wedge-shaped accommodation portion, specifically, between the sleeve 20 and the wedge-shaped accommodation portion 23a. The positioning frame 22 includes a body 22A and a flange 22B extending outward from an end of the body 22A, and is integrally formed of, for example, a synthetic resin material. Thus, the flange 22 is

Are formed, and in this example, the roller holding portions a (which are hollowed out) are provided in parallel with each other at six circumferentially divided positions of the body portion 22A.

That is, the roller holding part a is
When the roller 2 is mounted on the sleeve 20, the roller 2 is parallel to the sleeve 20, and the rolling roller 21 positioned and held by the roller holding portion a can be rotated in the same state as the sleeve 20. The shape of the roller holding part a is set to be slightly larger than the rolling roller 21 to ensure that the rolling roller 21 mounted on the roller holding part a freely rotates in a stable state without rattling. I do. A plurality of notches b (six in this example) are opened in the flange 22B of the positioning frame, and each notch b communicates with each roller holding part a. Therefore, even when the positioning frame 22 is mounted on the sleeve 20, each rolling roller 21 is inserted from the flange side through the notch hole b, and
a can be easily mounted.

FIG. 4 shows a configuration in which a resilient body S for supplementing the stability of the rolling roller 21 positioned and held by the roller holding portion a is additionally provided. The resilient body S is provided so as to always urge the rolling roller 21 in a direction opposite to the rotation when the rotation of the rotor 5 is the rotation of the winding (clockwise). Therefore, the rolling roller 21 that rotates in the roller holding unit by the bias of the elastic body S can always perform stable rotation smoothly, which is more preferable. Further, even if the strict dimensional relationship between the roller holding part a and the rolling roller 21 as described above is not guaranteed, the elastic body S adjusts it.

The operating lever 13 is provided with a flange 22 of the positioning frame.
It is arranged in indirect sliding contact with the end face of the outer frame body 23 via B. As shown in FIG. 3, the operating lever 13 is formed with a plurality of (six in this example) engaging portions 13b corresponding to the roller holding portions 22A of the positioning frame. A part 131 is provided. This engagement portion 13
The end of the rolling roller 21 mounted on the positioning frame 22 is inserted into b, and the operating lever 13 and the positioning frame 22 are assembled in such a state.

Further, the rolling roller 21 once mounted on the engaging portion 13b of the operating lever is provided with the retaining portion 13 of the engaging portion.

Engages with the inner wall surface of the wedge-shaped accommodating portion 23a and the outer peripheral surface of the sleeve 20 to restrict the reverse rotation of the rotor.

In particular, the rolling roller 21 bites into the small-diameter portion by line contact at the wedge-shaped accommodating portion 23a of the outer frame body. However, unlike the conventional case, the length of the rolling roller 21 can be set large. Therefore, the contact length is increased, the biting effect is increased, and accurate clutch operation is ensured. As described above, when the clutch unit 12 is operated (ON), the clutch unit 12 can be instantaneously switched by directly moving the rolling roller 21 with the operation lever 13 as described above, and the reverse rotation prevention state is immediately established. become. The clutch means 1
Needless to say, when the switch 2 is ON, it operates smoothly without restricting rotation in the normal rotation direction.

Next, when the clutch means 12 is not operated, that is, the reverse rotation of the rotor 5 is not restricted (OFF
Time). First, as shown in FIG.
, The operating lever 13 is driven clockwise in the opposite direction from the neutral position (not shown) via the operating rod 15. As a result, the operating lever 13 is directly
To the large-diameter portion side of the wedge-shaped accommodation portion 23a of the outer frame. Here, the positioning frame 22 slightly rotates around the sleeve 20 together with the rolling rollers 21. At this time, the rolling roller 21 becomes free in the wedge-shaped accommodating portion 23a.
At F, the rotation is not restricted in both the forward and reverse rotation directions of the rotor.

The fishing reel of the present invention has an advantage that the assembly around the clutch can be performed very easily. In the clutch assembling step, the rolling roller 21 is set in a state where it is positioned and held in the roller holding portion a through the notch hole b of the positioning frame 22,
Then, the operating lever 13 is brought into contact with the side surface of the flange portion 22B of the positioning frame, and the end of the rolling roller 21 is mounted on the engaging portion 13b. Therefore, the outer frame 23 is moved to the positioning frame 22.
Since the rolling roller 21 can be assembled after being mounted on the clutch, the operation of assembling the clutch can be performed extremely simply and efficiently.

Further, in the case of FIG.
In this case, the washer A may be attached to the roller holding portion a after passing through the engagement portion 13b of the operation lever and the cutout hole b of the flange portion 22B of the positioning frame, so that the assembling becomes easier.

Although the present invention has been described above, the present invention is not limited to the embodiment, and it goes without saying that other various modifications are possible without departing from the essence of the present invention. For example, the number of rolling rollers or the number of roller holding portions for holding 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, the rolling roller is directly moved by the operating lever, that is, by directly connecting the operating lever and the rolling roller, the instantaneous clutch switching operation is performed. Is performed, and a sharp switching can be guaranteed. In addition, the workability of assembling the click switch can be greatly improved, and the production efficiency can be improved.
