Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reverse rotation prevention device for regulating and controlling the rotation direction of a rotor in a fishing 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 enters an idle state in the guide slot, thereby rotating the shaft cylinder portion. Also,
In the reverse 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. Accordingly, Japanese Patent Application Laid-Open No. 6-22567
A reverse rotation preventive device as disclosed in Japanese Patent Publication No. 3 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.

In this conventional reverse rotation preventing device, a switching lever (rotating operating member) for controlling the operation of the annular holding member is provided.
Are provided integrally or integrally with the annular holder. Also, each rolling member is fitted into each guide slot of the annular holding body, so that it bites between the annular outer frame and the collar that regulates the outward movement of the rolling member, that is, performs a wedge action. In addition, it is possible to switch to be released on the contrary.

[0006]

However, the conventional anti-reverse device has a structure in which the rolling member is indirectly moved via the annular holder by operating the switching lever via the annular holder. For example, even if it is desired to switch the clutch immediately, the switching operation causes play, and the clutch is not necessarily switched instantaneously.

In other words, when the switching lever is moved, the annular holding member moves, and the rolling member fitted in the guide slot moves, so that a force transmission mechanism causes a time lag in the movement of the switching lever post member. There is a problem that instantaneous clutch switching cannot be performed and the effect becomes dull.

Also, when assembling the entire clutch, in the conventional reverse rotation preventing device, the annular outer frame is externally inserted with the annular holding body attached to the collar and the rolling members fitted in the respective guide holes. However, if even one of the several rolling members is not completely fitted in the guide slot, the rolling member becomes a hindrance, making it impossible to cover the annular outer frame, thereby deteriorating workability.

Furthermore, the reverse rotation preventing device for a fishing reel is composed of a combination of small components and is assembled to an important component such as a rotor rotating shaft.
Or the increase or decrease of grease has a great effect on the operation of the entire fishing reel, and the rotation of the handle feels rough,
It may also generate abnormal noise. Therefore, each component used in the reverse rotation prevention device requires very high accuracy, and the manufacturing cost increases.

The present invention has been made in view of the above circumstances. That is, an object of the present invention is to provide a fishing reel, particularly a spinning reel, that realizes instantaneous switching and stable operation and quality, can be easily assembled, and can reduce the manufacturing cost. Is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a device for preventing reverse rotation of a fishing reel according to the present invention will now be described in detail with reference to the drawings, including the operation thereof.

FIG. 1 is a sectional view showing a configuration example of a spinning reel according to the present invention. In the drawing, 1 is a reel body, 2 is a drive gear that rotates by operating a handle (not shown), 3 is a rotor rotating shaft that meshes with the drive gear 2, that is, a pinion gear, 4 is a main shaft, and the main shaft 4 is Pinion gear 3
And a plurality of components described later. 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 slider 8 has the main shaft 4 described above.
Are linked. A spool 9 is attached to the front end of the main shaft 4, and the reciprocating movement of the slider 8 also causes the spool 9 to reciprocate in a predetermined stroke in the front-rear direction.

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 etc. are interlocked with 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 operation and 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, especially the reverse rotation, can be selectively restricted by the reverse rotation preventing device 12 interposed between the reel body and the rotor rotation shaft (that is, the pinion gear 3). . That is, in this example, as shown in FIG. 2, the bearing 11 is externally fitted on the rotor side of the pinion gear 3, and the reverse rotation preventing device 12 is connected to the bearing 11.

The operating lever 13 interposed between the bearing 11 and the reverse rotation preventing device 12 causes
The operation of the reverse rotation prevention device 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 to an appropriate position on the reel body 1 by a screw 9 or the like. The operating lever 13 is connected to a positioning frame 22 of the reverse rotation preventing device 12 via a rolling roller 21 as described later, and is provided between the end of the operating lever 13 and the reel body 1 as shown in FIG. The spring 14 is stretched.

Due to the elasticity of the spring 14, the reverse rotation preventing device 12, more specifically, the operation lever 13, constantly urges a rolling roller 21, which will be described later, in a direction to bite the sleeve 20 in the wedge-shaped accommodating portion 23a to strengthen the engagement. Have been. In addition,
A check cam 15a of the operating body 15 is engaged with a cam hole 13a at an end of the operating lever 13, and by moving an operating lever 16 attached to an end of the operating body 15, the The operation lever 13 can be driven from the outside. (Fig. 1)

Here, the reverse rotation preventing device 12 and the operating lever 1
3 are interconnected as shown in FIG. The reverse rotation preventing device 12 according to the present invention includes a sleeve 20, a rolling roller 2.
1, an outer frame 23, a positioning frame 22, and an operating lever 13.

The sleeve 20 is fixed to the pinion gear 3 which is a rotor rotation shaft. A plurality of rolling rollers 21 are arranged around the sleeve 20. Outer frame 2
3 forms a wedge-shaped accommodating portion 23a between the inner wall 23b and the outer peripheral surface 20a of the sleeve 20. Further, the outer wall 23c of the outer frame body 23 is formed in a shape that is non-rotatably fitted to the fixing portion 1a of the reel body 1, for example, a polygon, and the reverse rotation preventing device 12 is easily attached to the reel body 1. It can be assembled and fixed.

The rolling roller 21 is formed in an elongated cylindrical shape, and is arranged and housed in the wedge-shaped housing portion 23a, more specifically, between the sleeve 20 and the inner wall 23b of the outer frame body 23. The positioning frame 22 is integrally formed of, for example, a synthetic resin material from the body, 22A, and a flange 22B extending outward from its end. By providing the flange 22B on the positioning frame 22A in this manner, its rigidity can be sufficiently ensured. A roller holding portion a on which the rolling roller 21 is positioned is formed on the body portion 22A of the positioning frame 22, and in this example, each roller is parallel to each other at six circumferential positions of the body portion 22A. The holding portion a is provided by being hollowed out.

The roller holding portion a is divided into a long portion a1 and a short portion a2 which are connected to each other, and is formed in a step shape. The rolling roller 21 is fitted into the long portion a1, and the rolling roller 21
It is supported in a state that allows rotation. Also, the roller holding unit a
Is formed in a shape shorter than the entire length of the rolling roller 21. Further, the short width portion a2 serves to reduce the rolling frictional resistance of the rolling roller 21 and to store excess grease around the rolling roller 21. Thereby, it is possible to prevent the rotation of the handle from being loose and generating abnormal noise.

Incidentally, the roller holding portion a is provided with the positioning frame 2.
2 is parallel to the roller rotation axis when the sleeve 2 is mounted on the sleeve 20. 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.

A plurality of notches b (six in this example) are opened in the flange portion 22B of the positioning frame 22, and each notch b communicates with each of the roller holding portions a. Therefore, even when the positioning frame 22 is mounted on the sleeve 20, the rolling rollers 21 can be inserted from the flange side through the cutout holes b and can be easily mounted on the roller holding portions 22a. When the rolling roller 21 is mounted on the positioning frame 22, the rolling roller 21 is held in a state of protruding from a cutout hole of a flange 22B formed in communication with the roller holding portion a. .

The operating lever 13 is disposed in indirect sliding contact with the end face of the outer frame 23 via the flange 22B of the positioning frame 22. As shown in FIG. 3, a plurality of (six in this example) engaging portions 13b corresponding to the roller holding portions 22A of the positioning frame 22 are formed on the operating lever 13, and the engaging portions 13b are Is provided with a retaining portion 131. The end of the rolling roller 21 mounted on the positioning frame 22 and protruding from the flange 22B is inserted into the engaging portion 13b. In this state, the operating lever 13 and the positioning frame 22 are inserted. Will be assembled.
Further, the rolling roller 21 once mounted on the engaging portion 13b of the operating lever 13 is provided with the retaining portion 131 of the engaging portion 13b.
As a result, it does not come out of the positioning frame 22.

In the above configuration, the rolling roller 21 positioned and held by the roller holding portion a of the positioning frame 22 is moved by the switching operation of the operating lever 13 to the wedge-shaped housing portion 23.
a, when the rolling roller 21 is located at the large diameter portion of the wedge-shaped housing portion 23a, it freely rotates in the released state, and when located at the small diameter portion, the sleeve 20 and the inner wall 23b of the outer frame body 23 are located. And an engagement state in which the engagement state is established. Now, in a case where the reverse rotation preventing device 12 incorporated in the reel body 1 is operated to be in an engagement state for restricting the reverse rotation of the rotor 5, a so-called clutch ON is assumed.

First, as shown in FIG. 5, the operating lever 16 is operated, and the operating lever 13 is driven counterclockwise from the neutral position (not shown) via the operating body 15. As a result, since the end of the rolling roller 21 is inserted and held in the engaging portion 13b of the operating lever 13, the rotation of the operating lever 13 causes the rolling roller 21 to move toward the small-diameter portion side of the wedge-shaped accommodation portion 23a of the outer frame 23. Moving. At this time, together with the rolling roller 21,
The positioning frame 22 slightly rotates around the sleeve 20.

By operating the operating lever 13 in this manner, the rolling roller 21 can be directly moved.
for that reason. The movement of the operating lever 13 instantly causes the rolling roller 2 to move.
1 and the switching effect becomes extremely good. In this state, when the rotor 5 rotates in the reverse direction, the rolling roller 21 is rotated by the inner wall 23 b of the outer frame 23 and the outer peripheral surface 20 a of the sleeve 20.
And restricts the reverse rotation of the rotor 5.

In particular, the rolling roller 21 has a wedge-shaped accommodation portion 23.
In the small-diameter portion of a, it will bite into the inner wall 23b of the outer frame body 23 by line contact. However, unlike the related art, since the length of the rolling roller 21 can be set to be long in structure,
The contact length is increased, the biting effect is increased, and accurate clutch operation is guaranteed. Thus, the reverse rotation prevention device 1
At the time of the operation operation (ON) of 2, the reverse rotation prevention device 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. When the reverse rotation prevention device 12 is ON,
It goes without saying that the motor operates smoothly without restricting the rotation in the normal rotation direction.

Next, when the reverse rotation preventing device 12 is not operated, that is, when the reverse rotation of the rotor 5 is not restricted (OFF
Time). First, as shown in FIG.
Is operated, and the operating lever 13 is driven clockwise from the neutral position (not shown) via the operating body 15. As a result, the operating lever 13 is directly
To the large-diameter portion of the wedge-shaped accommodation portion 23a. here,
Together with the rolling rollers 21, the positioning frame 22 is
Around a little. At this time, the rolling roller 21 becomes free in the wedge-shaped accommodating portion 23a, and does not restrict the rotation of the rotor 5 in both the forward and reverse rotation directions.

As described above, the fishing reel of the present invention has an advantage that the assembly around the reverse rotation preventing device 12 can be performed extremely easily. In the assembling process of the reverse rotation preventing device 12, the rolling roller 21 can be 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, so that the positioning is performed from the engaging portion side of the operating lever 13. It can be mounted on the roller holding part a of the frame 22. Therefore, since the rolling roller 21 can be assembled after the outer frame body 23 is mounted on the positioning frame 22, the operation of assembling the reverse rotation preventing device 12 is extremely simple and efficient.

The present invention has been described above. However, the present invention is not limited to the above-described embodiment, and it can be said that various other modifications are possible without departing from the essence thereof. Not even. For example, the rolling roller 21 or the roller holding portion a holding the roller 21 or the operating lever 13
The number of the engaging portions 13b, the retaining portion 1 of the operating lever 13
The shape of 31 or the provision of the operating lever 13 and the retaining portion 131 separately are not limited to the above embodiment, and can be appropriately selected.

[0036]

As described above, according to the present invention, by directly moving the rolling roller by the operating lever, it is possible to ensure good switching and to reduce the rolling frictional resistance of the rolling roller. In addition, it is possible to improve the quality by preventing the feeling of rattling and abnormal noise of the rotation of the steering wheel, and to greatly improve the workability of assembling the reverse rotation preventing device, thereby improving the manufacturing efficiency.
