DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing reverse rotation of a fishing reel, and more particularly to a device for preventing reverse rotation of 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. 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.

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, On the other hand, it is possible to switch so as to be released.

[0007]

However, in the conventional apparatus, when the rolling member is locked between the collar and the annular outer frame, that is, when the rolling member bites, there is play in the operation of the rolling member, so that the sensitivity of the reverse rotation preventing function is reduced. Inevitably worse. That is, there is no sharp effect. In an actual fishing spot, agile reel action is often required, and the conventional device cannot always sufficiently satisfy such a case. On the other hand, the annular outer frame body that regulates the outward movement of the rolling member has a unique and complicated inner peripheral wall shape, and requires high precision in manufacturing, resulting in high manufacturing costs.

The present invention has been made based on such technical background, and has a simple structure in a spinning reel.
It is an object of the present invention to provide a fishing reel reversal prevention device that realizes proper, agile, smooth operation, and has a sharp effect.

[0009]

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.

FIGS. 1 and 2 show an example of the configuration of a spinning reel according to this embodiment. In the drawing, 1 is a reel body, 2 is a handle, 3 is a handle arm, 4 is a drive gear rotated by the handle 2,
Reference numeral 5 denotes a pinion gear that meshes with the drive gear 4, and reference numeral 6 denotes a main shaft. The main shaft 6 supports a plurality of components described below, including the pinion gear 5. 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 fishing reel basically has two basic structures: 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 the gears 8, 9, the slider 10, and the like are interlocked with the rotation of the rotor 7. The spool 11 is slid back and forth through the intermediary. This rotation
By the sliding operation, the fishing line can be wound or fed out to the winding portion 11a of the spool 11 via the line roller 12.

Here, the spinning rule is configured so that the rotation of the rotor 7 can be selectively restricted by a clutch portion interposed between the reel body 1 and the rotor rotation shaft (ie, the pinion gear 5). I have. That is, in this example, as shown in FIG.
And a clutch 14 is connected to the bearing 13. The operation of the clutch 14 is controlled by a clutch lever 15 interposed between the bearing 13 and the clutch 14.

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

A bearing holder 19 is fitted around the bearing 13 mounted on the shaft of the pinion gear 5, and a bearing retainer 20 for fixing the bearing 13 is provided at an appropriate position on the reel body 1 by, for example, a screw 21 or the like. Is concluded.

Here, the clutch 14 in this embodiment is
5 and 6, a sleeve 22 fixed to a rotor rotation shaft (pinion gear 5), and an outer frame body 23 forming an annular pole accommodating portion 24 between an outer peripheral surface of the sleeve 22 and , Sleeve 22 and outer frame 2
3 includes a wedge-shaped pole 25 disposed between the sleeve 22 and a retainer 26 that holds the plurality of wedge-shaped poles 25 around the sleeve 22 in a detachable manner.

Each wedge-shaped pole 25 is arranged in an R-shaped groove 23 a provided on the inner peripheral surface of the outer frame 23. A pole holding portion 26a is formed on the retainer 26, and each of the pole holding portions 26a is formed.
One wedge-shaped pole 25 is mounted for each a. As will be described later, the rotation of the retainer 26 causes the pole holding portion 26a to rotate.
The posture of the wedge-shaped pole 25 inside can be raised or inclined.

The outer peripheral surface of the sleeve 22 and the inner peripheral surface of the outer frame body 23 are arranged concentrically at a predetermined interval D (see FIG. 5), and the wedge-shaped pole 25 can engage with these peripheral surfaces. It has become. That is, as shown in FIG. 5, the pole holding portion 26a of the retainer 26 is
When the wedge-shaped pole 25 in the pole holding portion 26a is disposed close to the position a, the position of the wedge-shaped pole 25 is regulated substantially along the diametrical direction. When the retainer 26 rotates as shown in FIG. 5 from the state shown in FIG. 5, the wedge-shaped pole 25 in the pole holding portion 26a is rotated.
Is inclined.

The retainer 26 has a clutch lever 1
5, the retainer 26 and the clutch lever 1
5 can also be separated by fitting. Also, both can be formed integrally. A tension spring 16 is stretched over the end of the clutch lever 15 as described above.
Due to the elasticity of the spring 16, the clutch lever 15
The wedge-shaped pole 25 is urged in the pole housing portion 24 in a direction to increase the engagement.

As shown in FIG. 5, a check cam 17a fixed to the end of the operating rod 17 is arranged in the engagement hole 15a at the end of the clutch lever 15. The check cam 17a is rotatable by operating the operation lever 18 via the operation rod 17.

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 14 can selectively restrict particularly the reverse rotation of the rotor 7.

Now, the clutch 14 is operated and the rotor 7
It is assumed that the reversal of is restricted. First, operating lever 1
By the operation 8, the check cam 17 a fixed to the end of the operation lever 17 via the operation rod 17 is arranged so as not to contact the clutch lever 15 as shown in FIG. 5. This allows the clutch lever 15
Is rotated counterclockwise in FIG. 5 by a sufficient elasticity of the spring 16, and the pole holding portion 26 a of the retainer 26 is rotated.
Approaches the corresponding R-shaped groove 23a.

In this state, as shown in the drawing, the length L1 of the wedge-shaped pole 24 in the clutch radial direction is
Is larger than the distance D between the outer frame 23 and the outer frame 23 (L1>
D). At this time, the rotation of the rotor 7 (sleeve 22) is free in the normal rotation direction A, and the rotation is
In, the wedge-shaped pole 25 cuts into the outer peripheral surface of the sleeve 22 and the inner peripheral surface (R-shaped concave groove 23a) of the outer frame body 23, respectively, whereby the rotation thereof is regulated.

Here, the end of the wedge-shaped pole 25 to be engaged with the outer peripheral surface of the sleeve 22 and the inner peripheral surface of the outer frame 23 has a different shape R (the center of curvature is offset). And it is easy to bite in the reverse direction B. That is, taking the uppermost wedge-shaped pole 25A of FIG. 5 as an example, the radius of curvature of the upper surface or lower surface on the right side is smaller than the radius of curvature of the upper surface or lower surface on the left side. The wedge-shaped pole 25
If the length is slightly larger than the distance D between the sleeve 22 and the outer frame body 23, it can be locked, and the end shape is not limited to the above.

For example, on the upper surface or the lower surface of the end portion shape, even if the right side and the left side have the same radius of curvature, it is naturally applicable. However, it goes without saying that the degree of engagement (the degree of biting) of the wedge-shaped pole 25 with respect to the outer peripheral surface of the sleeve and the inner peripheral surface of the outer frame varies depending on the shape of the end portion of the wedge-shaped pole 25, for example, how to set the radius of curvature.

By operating the clutch lever 15 in this manner, the wedge-shaped pole 25 can be directly moved. When the clutch 14 is operated (ON), the wedge-shaped pole 25 is directly moved to stand up as described above. Therefore, the clutch 14 is instantaneously and accurately operated, and the reverse rotation can be reliably prevented. Note that the O of the clutch 14
At N, the rotor 7 operates smoothly without restricting rotation in the normal rotation direction.

On the other hand, when the clutch 14 is not operated, that is, when the reverse rotation of the rotor 7 is not restricted (at the time of OFF), the operation of the operation lever 18 causes the operation of the check cam 1 via the operation rod 17.
7a is rotated as shown in FIG. This causes the clutch lever 15 to rotate as shown. Then, the wedge-shaped pole 25 in the pole holding portion 26a is tilted and comes out of the engaged state.

In this state, the wedge-shaped pole 25 is
Is smaller than the distance D between the sleeve 22 and the outer frame 23 (L2 <D). At this time, the rotation of the rotor 7 is free in both the normal rotation direction A and the reverse rotation direction B, and when the clutch is OFF, the rotation is not restricted in both the normal and reverse rotation directions.

As described above, since the wedge-shaped pawl 25 is not a rolling member but is formed in a cam shape, when the clutch 14 is turned on, the wedge-shaped pawl 25 does not move laterally and can stand or tilt at that position. There is no time loss such that the rolling member moves laterally and bites between the collar and the annular member as compared with the conventional one. Further, R on the inner peripheral surface of the outer frame 23 is
The formation of the concave groove 23a is easy, the manufacturing process can be simplified, and the manufacturing does not take much trouble.

The clutch ON / OFF can be switched simply by simply changing the attitude of the wedge-shaped pole 25, so that accurate clutch operation can be ensured and the effect can be switched sharply. Also, since there is little play in the movement of the wedge-shaped pole 25 and there is little play, no impact force acts upon switching,
The durability against the non-return action increases.

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 are possible 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. The shape of the R-shaped concave groove on the inner peripheral surface of the outer frame body may be an appropriate curved surface in addition to the case where it is strictly formed in an arc shape. Any shape may be used as long as it can be disengaged by standing or tilting the wedge-shaped pole.

[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 upright or inclined by the clutch lever, an instantaneous and accurate clutch switching operation is possible, and the switching effect becomes extremely sharp. In addition, since the wedge-shaped pole is merely moved up or inclined and does not move laterally as in the related art, there is little impact when engaging the outer peripheral surface of the sleeve and the inner peripheral surface of the outer frame, and the durability is improved. Further, the shape of the outer frame body is simple, the workability is good, and the cost is lower than in the past.
