Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adjusting device for adjusting the rotation of a spool of a fishing spinning reel by drag braking.

Conventionally, the knob adjustment device for adjusting the drag braking of the spool in a well-known spinning reel for fishing was performed by rotating a dial-type knob located on the front of the spool or the rear of the casing. When adjusting the drag braking inside, the angler adjusts the rotation of the dial knob while concentrating on the bait or the fish, so even if there is an adjustment scale on the housing, it is important to visually check it. By grasping the dial instantly,
Because the driver relies solely on the sensation of his or her hands and quickly turns the dial knob in the forward and reverse directions, not only is the drag adjustment not performed correctly, but it is also difficult to accurately return the dial knob to the standard braking force setting position. Furthermore, while conventional dial-type knobs can be rotated without limit over the entire adjustment range from the minimum braking position to the maximum braking position, it is difficult to rotate the knob arbitrarily back and forth within a limited range. . However, in reality, there is little need for drag adjustment over the entire adjustment range, and rather it is often used within a limited range.

In the present invention, the standard braking force is set in advance using a standard braking force setting dial knob, and when setting a setting value other than the above setting value, the braking force setting lever knob is activated. A spool braking force adjustment device for a spinning reel for fishing that is easy to operate and allows you to easily set the desired braking force by feeling the rotation angle of the lever-type knob for setting the braking force. The purpose is to obtain.

Thus, a dial type knob 6 and a knob cover 7 for setting the standard braking force are provided at the rear of the housing 1, and are arranged in parallel with the above-mentioned knob and knob cover to set the braking force to a braking force other than the above-mentioned standard braking force. Setting lever knob 8
is provided, and lever 17 of the latter lever type knob is provided.
The tip of the dial knob 6 is formed to protrude outward from the outer peripheral surface of the dial of the former dial type knob 6, that is, the knob cover 7.

In the embodiments described above, the engaging protrusion 8b provided on the flange portion of the braking force setting lever type knob 8 is configured to be able to engage with the engaging stepped portion 14c of the cam member 14. An engaging stepped portion is provided on the flange side of the lever-type knob 8 for setting the braking force, and the cam member 14

When the braking force setting lever type knob 8 is rotated, for example, about 150 degrees from the state shown in FIG.
b is rotated upward, and the cam member 14 moves to the left on the outer periphery of the shaft cylinder 9, resulting in the state shown in FIG. With this amount of movement, a new braking force is applied by the drag braking member. Braking force setting lever knob 8 is connected to brake spring 1
3, a rotational force acts on the inner cylinder 6a of the standard braking force setting dial knob 6 into which the hollow shaft cylinder 8a is fitted, but the outer cylinder 6c engages with the knob cover 7. The knob cover 7 has a hollow cylinder portion 1a.
Since it is locked by the meshing tooth portions 1f and 7d, it cannot be rotated.

In addition, the present invention has a lever-type knob on one side that can be operated by either the left or right hand to set a braking force other than the standard braking force, and a dial-type knob on the other side for setting the standard braking force. By making the tip of the knob protrude beyond the circumferential surface of the dial-type knob, the lever-type knob can be used to control the braking amount within the desired braking range, making it easy to operate the lever even when the lever is operated not by visual operation but by sensual operation with the hand. The amount of adjustment can be approximately determined by the direction, and light and fine adjustments can be easily made by touching the lever with the fingertip, frequently adjusting the reciprocating movement, and adjusting the length of the lever. Further, even if the dial type knob and the lever type knob are arranged side by side, their shapes are different, so there is an effect that there is no possibility of erroneous operation.
