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 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 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 holder is provided.
Are provided integrally or integrally with the annular holder, and each guide slot of the annular holder has a projection for urging each rolling member to bite into the collar, i.e., to perform a wedge action. Is provided. By this generation, the reverse rotation can be quickly acted.

[0007]

However, when the rolling member bites between the collar and the annular outer frame, the sensitivity of the reverse rotation preventing function is poor because the rolling member plays. Moreover,
Since the switching is performed by one movement of the annular holder,
Mechanical overload is applied to the annular holder and the rotating operation member. Further, the annular outer frame body that regulates the outward movement of the rolling member,
The shape of the inner peripheral wall is unique, and precision is required for manufacturing, and as a result, the manufacturing cost is increased.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a fishing reel reversing prevention device which realizes proper, agile, smooth operation with a simple configuration in a spinning reel and has a sharp effect.

With the configuration in which the wedge-shaped pawl is directly driven by the clutch lever in this way, a quick and accurate clutch section switching operation can be guaranteed.

[0019]

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.

FIG. 1 shows a configuration example of a spinning reel according to this embodiment. In the figure, 1 is a reel body, 4 is a drive gear rotated by a handle 2 (not shown), 5 is a rotor rotating shaft meshing with the drive gear 4, that is, a pinion gear, and 6 is a main shaft. It supports a plurality of components, which will be described later. A rotor 7 is connected and fixed to the shaft end of the pinion gear 5, and a handle 2
The rotation operation rotates the rotor 7 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 fishing reel basically has two mechanisms, a rotating mechanism for rotating the rotor 7 and a sliding 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 the gears 8, 9 and the slider 10 are linked to the rotation of the rotor 7.
The spool 11 is slid back and forth through the like. By this rotation / sliding operation, 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.

Here, the rotation of the rotor 7 can be selectively restricted by a clutch portion interposed between the reel body and the rotor rotation shaft (that is, the pinion gear 5). That is, in this example, as shown in FIG. 3, the bearing 13 is externally fitted on the rotor 7 side of the pinion gear 5 and the clutch 1
Connect 4 The operation of the clutch unit 14 is controlled by a clutch lever 15 interposed between the bearing 13 and the clutch unit 14.

The pair of clutch levers 15 are connected to the clutch section 14 as described later. As shown in FIGS. 4 and 5, a spring 16 is stretched at an end of the clutch lever 15. The elasticity of the spring 16 urges the clutch portion 14, specifically, the clutch lever 15, in a predetermined direction. A check cam 17a of the operating rod 17 is engaged between the ends of the clutch lever 15, and the operating lever 18 attached to the end of the operating rod 17 allows the clutch lever 15 to be moved from outside the reel body 1 to the outside. 15 can be driven (see FIGS. 1 and 2).

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

Here, the clutch unit 1 according to the present embodiment will be described.
Reference numeral 4 denotes a sleeve 22 fixed to a rotor rotation shaft (pinion gear 5) as shown in FIG. 5 or 6, a retainer 23 holding a plurality of wedge-shaped poles 24 around the sleeve 22, and an outer periphery of the sleeve 22. And an outer frame body 25 that forms an annular pole accommodating portion 26 with the surface.

The retainer 23 is divided into an inner retainer 27 and an outer retainer 28 which are rotatable relative to each other. Each of the inner retainer 27 and the outer retainer 28 has a pole holding portion 27a, 28a. One wedge-shaped pole 24 is attached to each of the corresponding pole holding portions 27a and 28a of the inner retainer 27 and the outer retainer 28. As will be described later, the relative rotation of the inner retainer 27 and the outer retainer 28 allows the wedge-shaped pole 24 in the pole holding portions 27a, 28a to stand or tilt.

The outer peripheral surface of the sleeve 22 and the inner peripheral surface of the outer frame 25 are arranged concentrically at a predetermined interval D (see FIG. 5), and the wedge-shaped pole 24 can be engaged with and disengaged from both peripheral surfaces. It has become. That is, as shown in FIG. 5, when the pole holding portions 27a of the inner retainer 27 and the pole holding portions 28a of the outer retainer 28 are accurately aligned and aligned, the wedge-shaped portions in the two pole holding portions 27a, 28a are formed. The position of the pawl 24 is regulated so as to stand substantially in the diameter direction of the clutch portion. When the inner retainer 27 and the outer retainer 28 rotate relative to each other from the state shown in FIG. 5, the wedge-shaped pole 24 in the pole holding portions 27a and 28a tilts.

Each of the inner retainer 27 and the outer retainer 28 has a pair of clutch levers (a clutch lever 29 on the inner retainer side and a clutch lever 30 on the outer retainer side) which are arranged substantially parallel to each other. . The clutch levers 29 and 30 constitute the clutch lever 15, and can be formed integrally with the inner retainer 27 and the outer retainer 28, respectively.

At the ends of the clutch levers 29 and 30,
Pins 29a and 30a are implanted.
A tension spring 16 is stretched between 9a and 30a. Therefore, the clutch lever 29 on the inner retainer side and the clutch lever 30 on the outer retainer side are urged toward each other by the elastic force of the spring 16 (FIG. 5, arrow A). The two clutch levers 29,
The biasing direction with respect to 30 coincides with the direction in which the wedge-shaped pole 24 strengthens the engagement in the pole housing portion 26. That is, the wedge-shaped pole 24 is urged between the inner peripheral surface of the outer frame body 25 and the outer peripheral surface of the sleeve 22 in a direction to strengthen the engagement.

Further, as shown in FIG. 5, between the ends of the clutch lever 29 on the inner retainer side and the clutch lever 30 on the outer retainer side, as shown in FIG. In the example, it is almost elliptical)
Are arranged. The check cam 17a is rotatable via the operating rod 17 by operating the operating lever 18.

In the above configuration, as described above, the rotation mechanism of the rotor 7 and the slide mechanism of the spool 11
By performing the rotation and sliding operations, the fishing line is wound on the winding portion 11a of the spool 11 via the line roller 12.
Can be wound up or fed out. When rotating the rotor 7, the clutch unit 14 causes the rotor 7 to rotate.
In particular, the reversal can be selectively restricted.

Now, the clutch unit 14 is operated and the rotor 7
It is assumed that the reversal of is restricted. First, operation lever 1
8, the check cam 17a fixed to the end portion of the clutch lever 29, 3 via the operating rod 17 as shown in FIG.
Arrange so that it does not touch the end of “0”. As a result, the clutch levers 29 and 30 approach each other due to the elasticity of the spring 16, and the inner retainer 27 and the outer retainer 2
The eight pole holding portions 27a, 28a are aligned.

In this state, as shown in the figure, the length L1 of the wedge-shaped pole 24 in the radial direction of the clutch portion is larger than the distance D between the sleeve 22 and the outer frame 25 (L1>).
D). At this time, the rotor 7 (sleeve 22)
In the normal rotation direction C, the rotation is free, and in the reverse rotation direction C ′, the wedge-shaped poles 24 are engaged (bite) with the outer peripheral surface of the sleeve 22 and the inner peripheral surface of the outer frame 25, respectively. Regulate the reversal.

Here, the end of the wedge-shaped pole 24 to be engaged with the outer peripheral surface of the sleeve 22 and the inner peripheral surface of the outer frame 25 has an irregular shape R (the center of curvature is offset). Therefore, it is easy to bite in the reverse rotation direction C ′. That is, taking the uppermost wedge-shaped pole 24a of FIG. 5 as an example, the radius of curvature of the upper or lower surface on the right side is smaller than that of the upper or lower surface on the left side. The degree of engagement differs depending on how the curvature radius is obtained. If the length of the wedge-shaped pole 24 is slightly larger than the distance D between the sleeve 22 and the outer frame body 25, the wedge-shaped pole 24 can be in the locked state, and is not limited to the above-described end shape. . For example, even if the end portions have the same radius of curvature on the left side and the right side, they can be naturally used. When the space between the clutch levers 29 and 30 is parallel as shown in FIG. 5, the wedge-shaped pawl 24 is completely locked.

By operating the clutch levers 29 and 30 in this manner, the wedge-shaped pawl 24 can be directly moved. When the clutch unit 14 is operated (ON),
By directly moving the wedge-shaped pole 24 as described above, it is raised or tilted. Therefore, the clutch section 14 is quickly and accurately operated, and the reverse rotation can be reliably prevented. When the clutch unit 14 is ON, the rotor rotation shaft operates smoothly without being restricted from rotating in the normal rotation direction.

On the other hand, when the clutch section 14 is not operated, that is, when the reverse rotation of the rotor 7 is not restricted (when OFF),
By operating the operation lever 18, the check cam 17a is rotated via the operation rod 17 as shown in FIG. As a result, the clutch levers 29 and 30 expand as shown (arrow B),
The inner retainer 27 and the outer retainer 28 rotate relative to each other. Then, the wedge-shaped poles 24 in the pole holding portions 27a and 28a are tilted and come out of the engaged state.

In this state, as shown in FIG.
The length L2 of the clutch part 4 in the radial direction is smaller than the distance D between the sleeve 22 and the outer frame 25 (L2 <D). At this time, the forward rotation direction C and the reverse rotation direction C ′ of the rotor 7 are
In both cases, the rotation is free, and when the clutch unit is OFF, the rotation is not restricted in both the forward and reverse directions.

As described above, since the wedge-shaped pawl 24 is not a rolling member but is formed in a cam shape, when the clutch portion 14 is turned on, it can stand or tilt at the position. As compared with the conventional one, there is no time loss in which the rolling member moves laterally and bites between the collar and the annular outer frame.

By simply changing the attitude of the wedge-shaped pole 24, the clutch portion can be switched ON / OFF, and accurate operation of the clutch portion can be ensured, and the switching can be performed sharply. In addition, since there is no lateral movement in the movement of the wedge-shaped pole 24, no impact force acts and the check strength can be significantly increased.

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 wedge-shaped poles and the like are not limited to the above embodiment, and can be appropriately selected.

[0042]

As described above, according to the present invention, a proper reverse rotation preventing operation is guaranteed in this kind of spinning reel. By moving the wedge-shaped pole directly by the clutch lever, a quick clutch section switching operation is possible, and the switching effect becomes extremely sharp. Since the operating noise can be greatly reduced, it is highly usable. The shape of the outer frame is simple, has good workability, and is inexpensive.
