Description

[Detailed Description of the Invention] The present invention relates to an improvement of a reversing device for a spinning reel for fishing.

When throwing a bait with a spinning reel, the position where the fishing line hanging on the line roller of the rotor's bail arm can be reached with the index finger of the hand holding the fishing rod (hereinafter referred to as the centering position)
It is desirable that the rotor be held at

In order to achieve this purpose, it is considered that the anti-reversal pawl has one locking tooth and the rotor's anti-reversal position is aligned with this. Therefore, it is known from Japanese Utility Model Publication No. 57-12843 and Japanese Utility Model Publication No. 55-51174 that this centering mechanism is used in combination with a normal reverse rotation prevention gear. ing.

However, in the former method, the rotational positions of the anti-reverse pawl and the locking pawl that engage with the anti-reverse pawl and the centering pawl, respectively, are switched in three stages depending on the engagement position of the same cam or operating rod. Because of this, it is easy to make mistakes during fishing operations, and in particular, there are defects such as turning the cam in the wrong direction or turning the cam too far, resulting in missed prey.

In addition, in the latter method, the reversal prevention pawl that engages with the reversal prevention ratchet wheel and the locking pawl that engages with the centering ratchet wheel are each turned on and off using two independent operating members. The risk of erroneous operation has been reduced, but the anti-reverse pawl, anti-reverse pawl, centering pawl, and locking pawl, as well as the operating cams for the anti-reverse pawl and locking pawl, are not connected to the rotor. Since it is stored on the rear bottom surface, there is a defect that it is extremely difficult to apply it especially to small reels due to the space.

The present invention improves these defects by fixing a ratchet wheel with one locking tooth on each or either of the rotor rotation shaft and the drive shaft, and a reversal prevention ratchet wheel with locking teeth around the entire circumference. , a locking pawl and a reversal prevention pawl that can be freely engaged with the ratchet wheel and the reversal prevention pawl, respectively, are pivoted in the housing, and the housing is provided with a reversal prevention pawl at the same time as the locking pawl is separated from the ratchet wheel. The main feature of the present invention is to provide an operating member for separating the anti-reversal pawl from the anti-reverse ratchet wheel, and further provide a separate operating member on the casing for separating the anti-reverse pawl from the anti-reverse ratchet wheel.

To explain an embodiment of the present invention with reference to the drawings, a pinion 2 provided at the rear end of a rotor rotation shaft 1 of a spinning reel meshes with a drive gear 4 of a drive shaft 3, and as is known, rotation of the drive shaft 3 causes the rotor to rotate. A ratchet wheel 6 is formed to be able to rotate the rotor 5 and has one locking tooth on the rotor rotating shaft 1.
However, each of the drive shafts 3 has a reverse rotation prevention ratchet wheel 7 fixed thereto having a large number of locking teeth on its circumferential surface.

Further, a locking pawl 9 that can freely engage with the ratchet wheel 6 is pivotally mounted in the housing 8, and an engaging portion 10 provided at the other end of the locking pawl 9 can freely slide on the housing 8. When the operating member 11 is slid backward by the knob 13, the operating member 12 engages and pulls the engaging portion 10, and the locking claw is engaged. An elastic member 15 having an elastic protrusion 14 is fixed to the shaft attachment portion of the locking pawl 9, and the elastic protrusion 14 is attached to the drive shaft 3. It is formed to resiliently engage with a spool shaft oscillating gear 16 fixed to the spool shaft.

A reversal prevention pawl 17 that can freely engage with the reversal prevention pawl wheel 7 is pivotally attached to the rear part of the housing 8, and an engaging portion 18 and an engaging portion 19 are substantially opposed to the reversal prevention pawl 17.
The engaging portion 18 is provided with an operating protrusion 21 of an operating member 20 that is slidably attached to the housing 8;
The engaging portions 19 are formed to be able to freely engage with the rear end actuating portions 22 of the operating member 11, and furthermore, an elastic protrusion 2 that engages with the anti-reverse ratchet wheel 7 is provided at the shaft attachment portion of the anti-reverse pawl 17.
An elastic member 24 provided with 3 is fixed.

Since the embodiment of the present invention is constructed as described above, when throwing a fishing line, the operation member 20 is slid to the forward position and the reversal prevention pawl 17 is moved away from the operation member 11 with the reversal prevention pawl wheel 7 separated. When the rotor 5 is slid to the forward position, the locking pawl 9 is engaged with the ratchet wheel 6, and the rotor 5 is locked and held at the centering position. (See Figures 3 and 4) In addition, when preventing the rotor 5 from reversing, the first
When the operating member 20 is slid to the rear position as shown in the figure, the reversal prevention pawl 17 becomes engaged with the reversal prevention ratchet wheel 7, and the engaging portion 19 of the reversal prevention pawl 17 presses and slides the operational member 11 forward. Locking claw 9
is also engaged with the ratchet wheel 6.

In this case, however, the rotor 5 can be freely rotated in the fishing line winding direction by the elastic member 15 acting as a spring against the oscillating gear 16 and the elastic member 24 acting as a spring against the anti-reverse ratchet wheel 7.

Further, when the operating member 11 is slid to the rear position from this state, its operating portion 12 separates the locking pawl 9 from the engagement position of the ratchet wheel 6, and at the same time, the rear end operating portion 22 of the operating member 11 moves from the engaging position. 19 to separate the reversal prevention pawl 17 from the reversal prevention pawl wheel 7, and the rotor 5 becomes freely reversible in the forward and reverse directions as shown in FIG.

In the embodiment shown in FIG. 6, the operating portions 12 and 22 of the operating member 11 are formed as cams,
The operating member 20 is also a cam lever type, and ring-shaped springs 15 and 24 are used as means for making the locking pawl 9 and the reverse prevention pawl 17 freely engageable and detachable from the ratchet wheel 6 and the reverse prevention ratchet wheel 7, respectively. This is the case when .

Further, in the embodiment shown in FIG. 8 and FIG.
are provided respectively, and a locking pawl 9 and a reversal prevention pawl 17 are provided.
Clamping plate springs 15 and 24 are used as means for engaging and disengaging the ratchet wheel 6 and anti-reverse ratchet wheel 17, respectively.

Furthermore, in the embodiment shown in FIGS. 10 to 14, a ratchet wheel 6 and a reversal prevention ratchet wheel 7 are provided on the rotor rotating shaft 1, and a locking pawl 9 and a reversal prevention pawl 17 are coaxially supported so that both can be operated. Cam operating part 1 at the tip of member 11
2, and means for engaging and disengaging the locking pawl 9 and the reverse prevention pawl 17 with respect to the ratchet wheel 6 and the reverse prevention ratchet wheel 7 are respectively engaged with elastic members 25 provided on the drive shaft 3 and having a large number of elastic pieces. It was designed to match.

The present invention is a spinning reel in which the rotor centering mechanism and the reversal prevention mechanism are operated by independent and separate operation parts to prevent erroneous operation when throwing a fishing line. Since both the pawl and the claw are pivoted inside the housing, the rotor's reversal prevention mechanism and centering mechanism can be stored separately and compactly even in small reels with a small space at the rear bottom of the rotor. In this state, both the anti-reverse pawl and the centering pawl can be simultaneously moved to the disengaged position by operating the operating member, and the mechanism has an excellent feature of being extremely simple in construction and operation.
