Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a reversal prevention device for a spinning reel or a double bearing reel.

A so-called silent stopper system that does not generate noise during forward rotation is known as a means to prevent reverse rotation when a force in the reverse direction is applied to the rotor or double-bearing spool of a spinning reel. In the silent stopper, the anti-reversal ratchet is also used for the engagement bullet of the elastic actuating piece, so the elastic actuating piece does not reliably engage the engaging pawl and the locking pawl does not engage the anti-reverse ratchet. There are defects such as skipping over the mating teeth, resulting in a skipped stitch phenomenon, and the elastic actuating piece being easily worn and lacking in durability.

The present invention has been made to improve these defects, and the depth of the teeth of the rotating member that rotates forward or backward in conjunction with the handle shaft is adjusted to the depth of the engagement teeth of the anti-reversal pawl. A synthetic rubber,
The gist is that an elastic member made of synthetic resin is fixed, and an operating protrusion that deeply engages with the teeth of the gear is integrally formed on the elastic member.

An embodiment of the present invention will be described with reference to the drawings. As is well known, a rotating shaft cylinder 2 to which a rotor 1 of a spinning reel is fixed is formed to rotate forward or backward in conjunction with a handle shaft 3. A reverse prevention pawl 5 and a gear 6 are fixed to the front part side by side.

Therefore, the depth of the tooth portion 7 of the gear 6 is deeper in the axial direction than the engaging tooth portion 8 of the anti-reversal pawl 5, and the engaging side surface 7 on the reverse direction side is shaved in an inclined shape. ing.

Further, a metal locking pawl 9 that can freely engage with the anti-reverse ratchet wheel 5 is pivotally attached to the front surface of the casing 4 with a pin 10, and an engaging piece 11 at one end of the locking pawl 9 is supported by the casing 4. The locking pawl 9 has an actuating protrusion 15 on its surface that engages with the gear 6. An elastic member 16 made of synthetic rubber, synthetic resin, etc. is integrally fixed.

Therefore, the operating protrusion 15 is formed to be long so as to deeply engage with the teeth 7 of the gear 6, and when the locking pawl 9 engages with the engagement tooth 8 of the anti-reverse ratchet 5, the outer periphery of the gear 6 It is preferable to form it so that it is bent in a plane. In addition, 17 in the figure is a stopper of the locking pawl 9.

Since the embodiment of the present invention is constructed as described above, when the cam 14 is held in the position shown in FIGS. The locking pawl 9 is rotated outward to separate from the anti-reversal pawl 5 for engagement with the gear 6, and when the rotating shaft cylinder 2 is reversed, the elastic protrusion 15 is engaged for engagement with the gear 6. For seizure purposes, the locking pawl 9 is rotated inward to engage with the anti-reverse ratchet wheel 5 to prevent the rotor 1 from reversing.

Furthermore, when the engaging piece 11 of the locking pawl 9 is pressed by the cam 14 on the operating rod 13 as shown in FIG. The elastic protrusion 15 does not engage with the gear 6.
The rotor 1 can freely rotate in the normal direction simply by engaging and firing.

In the above embodiment, the anti-reversal pawl 5 and the gear 6 are fixed to the rotating shaft cylinder 2 of the rotor 1, but they can also be provided on the handle rotating shaft 3, or the gear 6 can be formed integrally with the rotor 1. Of course, the present invention can also be applied to a reversal prevention device for a double bearing type reel.

In the present invention, the rotating member that rotates forward or backward in conjunction with the handle shaft is provided with a reverse prevention pawl that can freely engage with the locking pawl and a gear that engages with the operating protrusion. By using anti-reversal pawls and gears that are optimally shaped for the functions required for the engagement action of the operating protrusion and the engagement action of the operating protrusion, the separation action during forward rotation and the locking action during reverse rotation of the locking pawl are ensured smoothly. It can be carried out.

In addition, the present invention is particularly characterized in that the gear has a tooth portion deeper than the engaging tooth portion of the reversal prevention pawl wheel formed in the axial direction, and a long operating protrusion engages with this tooth portion to spring the locking pawl. Therefore, the actuating protrusion can elastically urge the locking pawl inwardly or outwardly at a wide rotation angle to ensure that the locking pawl engages or disengages from the engagement teeth of the anti-reversal ratchet. In particular, it is possible to reliably prevent the phenomenon of stitch skipping of the locking pawl when switching instantaneously from normal rotation to reverse rotation.
