Description
Field of the Invention
The present invention relates to a click sound generator for making a click sound when the rotor of a spinning reel is rotated to wind a fishline.
Background of the Invention
A changer for enabling or preventing the backward rotation of a rotor of a spinning reel and a changer for unabling or preventing the generation of a click sound comprise a ratchet wheel, a pawl, a clicking toothed wheel, and a clicking claw. In a conventional click sound generator, a click sound generation selecting lever for manipulating a clicking claw is provided separately from an anti-reversing lever for selecting the forward or backward rotation of a rotor. In another conventional click sound generator, a clicking claw is changed over through a separate lever directly coupled to an anti-reversing cam.
Each of the conventional click sound generators has problems, however, in that a large number of component parts is required and the construction of the click sound generator is complicated making it troublesome, difficult, and time-consuming to assemble. Also, the prior art click sound generators are expensive and relatively heavy, which hinders the reduction in the size and weight of a reel.
Summary of the Invention
An object of the present invention is to overcome the problems and disadvantages of the prior art.
An object of the present invention is a click sound generator for a spinning reel wherein rotation of an anti-reversing lever between a first position enabling reverse rotation of the reel and a second position preventing reverse rotation of the reel moves the click sound generator from a position wherein no click sound is generated to a position when a click sound is generated.
Another object of the present invention is a click sound generator including a single lever that prevents or enables the generation of a click sound and also prevents or enables reverse rotation of the spinning reel.
A further object of the present invention is a click sound generator that is easy to assembly, light-weight, and inexpensive to manufacture.
These and other objects are attained by a click sound generator for a spinning reel having a reel body supporting an anti-reverse lever mounted on a rotatable anti-reverse lever shaft for rotation between a reverse rotation prevention position and a reverse rotation enabling position comprising a clicking toothed wheel, a clicking claw mounted on the anti-reverse lever shaft, a spring for biasing the clicking claw into contact with the clicking toothed wheel when the anti-reverse lever shaft is in the reverse rotation prevention position, and an anti-reverse lever cam provided on the anti-reverse lever shaft for contacting the clicking claw to move the clicking claw against the bias of the spring and out of contact with the clicking toothed wheel when the anti-reverse lever is rotated from the reverse rotation prevention position to the reverse rotation enabling position.

Detailed Description of the Preferred Embodiment
In the click sound generator for a spinning reel of the present invention, an anti-reversing lever for preventing the backward rotation of a rotor and for selecting the generation or non-generation of a click sound is provided with an anti-reversing lever cam. A clicking claw can be disabled by the anti-reversing lever cam, and an anti-reversing pawl can be disabled by the groove end of an anti-reversing lever shaft. The selection of forward and backward rotation of the rotor and the selection of generation or non-generation of the click sound can be simultaneously performed by the anti-reversing lever. This reduces the number of component parts of the click sound generator and simplifies the construction thereof.
In the click sound generator, a clicking toothed wheel and a ratchet wheel are secured to a quill or similar member that projects out of a front portion of a body of a spinning reel. The clicking claw, which can be optionally engaged with or disengaged from the clicking toothed wheel, is supported on an anti-reversing lever shaft projecting out of the front portion of the body of the reel so that the clicking claw is turnable as well as movable in the axial direction of the anti-reversing lever shaft. A spring urges the clicking claw in a direction to engage the claw with the clicking toothed wheel. The anti-reversing pawl is supported at the front portion of the body of the reel so that the pawl is turnable. The anti-reversing pawl is also engaged with the ratchet wheel by a guide spring so that the pawl can be optionally disengaged from the ratchet wheel. The anti-reversing lever cam has a cam surface for moving the clicking claw and is secured to the front end portion of the anti-reversing pawl, so that the clicking claw and the anti-reversing pawl can be moved in the axial direction of the anti-reversing lever shaft and turned against the forces of the springs by the rotation of the anti-reversing lever shaft.
As shown in FIGS. 3 and 4, a quill 4 is rotatably supported by a bearing 3 in a front bearing hole 2 of a body 1 of a spinning reel in such a manner that the quill is immovable in the axial direction thereof. A portion 4a of the quill 4, which has a unicircular cross section, projects out of the front portion 1a of the reel body 1. A clicking toothed wheel 7 having a shaft hole 5 reviews the portion 4a so that the quill 4 and the clicking toothed wheel 7 are not rotatable relative to each other.
As shown in FIGS. 1 and 3, a ratchet wheel 6 is non-rotatably fitted on the outside circumferential surfaces of the boss 7a of the clicking toothed wheel 7. A rotor 8 is secured to the front end portion of the quill 4 by a nut 9. A pinion provided on the rear end portion of the quill 4 (but not shown in the drawings) is engaged with a master gear (not shown) supported in the reel body 1 so that the quill, the ratchet wheel 6, the clicking toothed wheel 7, and the rotor 8 are rotated together in conjunction with the rotation of a handle (not shown).
A main shaft 10 is secured to the front end portion of a spool (not shown) and is movably inserted through the quill 4 so that the main shaft is reciprocated backward and forward by a reciprocative sliding mechanism (not shown) in conjunction with the rotation of the handle.
An anti-reversing lever shaft 11 is supported by the reel body 1 in parallel with the main shaft 10 so that the anti-reversing lever shaft 11 is immovable in the axial direction thereof. A changeover, anti-reversing lever 12 is secured to the anti-reversing lever shaft 11, at a portion that projects out of the rear portion of the reel body 1. A clicking claw 13 is provided on a portion of the anti-reversing lever shaft 11, which projects out of the front portion 1a of the reel body 1. The clicking claw is turnable as well as movable in the axial direction of the anti-reversing lever shaft 11.
As shown in FIG. 5, an anti-reversing lever cam 14 is secured to the front end of the anti-reversing lever shaft 11 by a screw 15 so that the clicking pawl 13 is prevented from coming off the anti-reversing lever shaft 11. A spring 16 is interposed between the clicking claw 13 and a boss 11a or collar of the anti-reversing lever shaft 11 and urges the clicking claw 13 in a direction to engage the clicking toothed wheel 7. The clicking claw 13 and the clicking toothed wheel 7 can be optionally engaged with or disengaged from each other, as shown in FIGS. 1 and 3.
An anti-reversing pawl 17, which can be optionally engaged with or disengaged from the ratchet wheel 6, is rotatably supported by a stepped screw 18 or the like at the front portion 1a of the reel body 1. The end of a guide spring 19 wound in an annular groove 7b of the outside circumferential surface of the boss 7a of the clicking toothed wheel 7 is engaged on the anti-reversing pawl 17. The frictional force of the guide spring 19 on the anti-reversing pawl 17 acts to engage the pawl with the ratchet wheel 6 so that the pawl can be disengaged therefrom.
As shown in FIG. 5, the anti-reversing lever cam 14 has a plurality of projections 14a (for example two projections located in symmetric positions in this embodiment) on the peripheral portion of the cam. One side of each of the projections 14a is provided with a cam surface 14b. The boss 11a of the anti-reversing lever shaft 11 is provided with a groove 11b for engaging the anti-reversing pawl 17 with the ratchet wheel 6.
When the anti-reversing lever cam 14 is turned from a position shown in FIG. 1 to a position shown in FIG. 2, by movement of the anti-reversing lever 12, the clicking claw 13 is moved in the axial direction of the anti-reversing lever shaft 11 by the cam surface 14b against the force of the spring 16 so that the clicking claw is separated from the clicking toothed wheel 7. At that time, the bent projection 17a of the anti-reversing pawl 17 is turned in the circumferential direction of the reel body 1 about the stepped screw 18 or the like, from a position shown in FIG. 1 to a position shown in FIG. 2, by the groove end 11c of the anti-reversing lever shaft 11 against the frictional force of the guide spring 19. The tip 17b of the anti-reversing pawl is separated from the ratchet wheel 6, so that the prevention of backward rotation of the rotor 8 is ceased and the generation of a click sound is stopped. The force of a tension spring 20 is applied in such a direction that the click sound is generated when each tooth 7c of the clicking toothed wheel 7 separates from the clicking claw 13.
