Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved drag adjustment device for a spinning reel.

Conventional drag adjustment devices are operated by simply rotating the adjustment knob that is in pressure contact with the drag shear, and in this case, the scale displayed on the adjustment knob is displayed starting from the point at which drag braking begins. is the current situation.

However, it is extremely difficult to correctly align the starting point of this display scale with the starting point of drag braking due to accuracy errors in the drag washer and the springs that press against it.

In addition, the drag device also has a defect in which the drag shear becomes worn or the spring weakens during long-term use, causing the base point of drag braking to no longer match the starting point of the display scale.

The present invention has been developed to improve these deficiencies, and an adjustment tube that presses the drag shear of the spool sliding shaft is screwed into a tube protruding from the rear of the spinning reel housing through a spring so that it can move forward and backward. , the handle tube slidably fitted in the axial direction of the adjustment tube and the adjustment tube are fitted to each other so that the position in the circumferential direction can be rotatably adjusted by the engagement uneven portion, and the grip tube is activated. The gist of this is that the adjustment cylinder is biased in the opposite direction.

To explain an embodiment of the present invention with reference to the drawings, a sleeve is fitted to the rear part of the housing 1 of the spinning reel so as to be freely axially movable and rotate integrally with the occluded shaft portion 2' of the spool sliding shaft 2. A drag washer 8 is rotatably supported on the sleeve 3 and includes a washer 4 that engages with the sleeve 3 and a washer 7 that engages with a slot 6 of a cylindrical body 5 protruding from the housing 1. An adjusting cylinder 9 is fitted onto the rear end surface of the drag washer 8 and is pressed into contact with the cylindrical body 5 via a spring 10.

Further, a bottom part of a handle tube 12 formed to be worn on the outside of the cylinder body 5 is fitted into the protruding shaft part 11 formed at the rear end of the adjustment cylinder 9, so that the bottom part of the handle cylinder 12 is freely axially fitted. Screw 1 screwed into
The spring 14 interposed between the collar head 13' of No. 3 urges the handle tube 12 toward the adjustment tube 9, and the convex portion protrudes opposite to the outer circumference of the adjustment tube 9. 15.15 is a recessed portion 16. which is bored around the inner bottom surface of the handle tube 12. 16. 16...
Further, protrusions 17 and 17' are provided on the outer surface of the cylinder body 5 and the inner surface of the handle tube 12, respectively, to restrict rotation of the handle member 12.

In the figure, 18 is a display scale provided on the handle barrel 12, 19 is a spool fixed to the tip of the spool sliding shaft 2, 20 is a rotor rotated from the handle shaft 21 via a drive gear 22 and a pinion 23, 24 is a sliding piece of the spool sliding shaft 2, and 25 is a braking reference point provided at an arbitrary position on the housing 1 so as to face the display scale 18.

Since the embodiment of the present invention is constructed as described above, after the adjusting cylinder 9 is screwed into the cylinder body 5 to the position where the drag washer 8 starts to perform a braking action, the handle cylinder 12 is pushed backward against the spring 14. The fitting position of the protrusion 15 of the adjustment tube 9 and the recess 16 of the handle tube 12 is adjusted so that the starting point of the display scale 18 coincides with the braking reference point 25, and the two are fitted together. In addition, even if the starting point of the display scale 18 and the braking reference point 25 become mismatched due to wear of the drag washer 8, embrittlement of the spring 14, etc. during long-term use of the drag device, the same procedure as described above will be applied. The fitting positions of the grip tube 12 and the adjustment tube 9 are rotated and adjusted to match.

After aligning the starting point of the display scale 18 of the handle tube 12 with the braking reference point 25 of drag braking in this way, the handle tube 12 is rotated to a predetermined display scale and the fishing line is wound up. When a large load greater than the drag braking force corresponding to the set display scale is applied, the spool sliding shaft 2 slips and rotates.

In the above embodiment, the adjustment tube 9 has a convex portion 15.15, and the handle tube 12 has a concave portion 16, 16.16, but conversely, the adjustment tube 9 has a concave portion 16.16. ..., a convex portion 15.15 can also be formed on the handle tube 12,
Also, the protrusions 17, 17' are not absolutely necessary.

Of course, the present invention allows the drag action of the spool sliding shaft to be adjusted by rotating the handle tube that is integrally connected to the adjustment tube using spring biasing force, and adjusting the degree of pressure contact of the adjustment tube against the drag washer to be strong or weak. In particular, the handle tube has an engaging uneven portion that allows rotation of the fitting position in the circumferential direction with the adjustment tube, so the drag shear may wear out with long-term use and the frictional force changes, or the drag shear may be pressed against the drag shear. Even if the starting point position of the display scale does not match the braking reference point due to embrittlement of the spring, etc., it is possible to correct it again by rotating the fitting position of the handle tube.
Moreover, future adjustment operations can be performed simply by pulling the handle tube against the spring and rotating the engagement position of the retaining uneven portion, making it possible to readjust the adjustment extremely easily and quickly. It has characteristics and practicality.
