Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a reel drag system that is provided at the rear end of the spool shaft of a fishing reel and controls the rotation of the spool that is attached to the tip of the spool shaft. In particular, it eliminates the phenomenon of sticking between various washers and other parts installed in the drag system, ensuring smooth rotation of the spool shaft in a drag-free state, and crimping when the drag is at its maximum. This invention relates to a drag system for a fishing reel that can increase the fishing power of the reel by increasing the force.

B. Prior Art The drag system of a commonly used fishing reel usually uses a large number of washers made of various standards and materials in order to increase the fishing force when the drag is maximized.

Among these washers, a large number of Teflon washers had to be used to reduce the sliding friction between the washers during drag-free operation.

Therefore, the conventional drag system configured in this way requires a large number of washers (8 to 10 pieces) including expensive Teflon washers, so it is difficult to achieve a certain level of fishing force when the drag is at its maximum. However, this has led to a decrease in productivity and an increase in manufacturing costs.

Furthermore, as the drag adjustment knob is adjusted, a sticking phenomenon is induced between the washer and the washer or the member adjacent to the washer, which are pressed into close contact with each other, making it difficult to rotate smoothly when the drag is free. There were other defects and inconveniences.

c.Means for solving the problems The present invention was devised by taking into consideration the defects and inconveniences of the conventional drag system. Although the number of washers required is greatly reduced by using a washer, etc., the fishing force at maximum drag is significantly increased, and the sticking phenomenon induced between the washers and the adjacent members is suppressed by using the elasticity of a separate coil spring. It has been resolved.

d Examples The present invention will be described in detail below with reference to the accompanying drawings.

As shown in the drawings, the rear end portion of the spool shaft 12 protrudes inside a circular tubular retaining portion 11 formed at the rear portion of the reel body 10. The insertion part 1
A pressure adjustment screw 14, in which a compression spring 13 is housed, is screwed from the outside of 1. A click metal 15 is provided between the compression spring 13 and the spool shaft 12 and has a shaft tube portion 15a and a click gear portion 15b which are inserted into the rear end of the spool shaft 12.
and metal washers 16, 17, etc. are interposed. A drag adjustment knob 18 is fixedly covered by a fixing screw 19 on the outer side of the pressure adjusting screw 14 .

A support tube 15c having the same outer diameter as the diameter of the click gear part 15b is formed extending rearward at the rear peripheral edge of the click gear part 15b of the click metal 15. Support tube 15c and its inner central shaft tube portion 15a
An annular hollow portion 15d having a constant width and depth is formed between the two, and a coil spring 20 having appropriate elasticity is interposed within the hollow portion 15d. A washer 21 having a high coefficient of friction, such as asbestos made of rubber and asbestos, is interposed between the outer end of the coil spring 20 and the metal washer 17. Washiya 2
1 and the metal washer 17 are fitted into the shaft tube portion 15a, and are resiliently supported by springs 20, 13 on the front and rear thereof. In the drawing, unexplained symbol 11a
22 is a stainless steel plate washer interposed between the rear end of the compression spring 13 and the inner surface of the pressure adjustment screw 14;
indicates a spool, and 24 indicates a rotor.

The effects of the embodiment of the present invention constructed as described above are as follows.

FIG. 2A shows the drag-free state. At this time, the pressure adjustment screw 14 is completely moved backward to the selected limit position by the screw adjustment of the drag adjustment knob 18, and the washers 21 and 17 fitted in the shaft tube part 15a of the click metal 15 are moved forward. support tube 15c end and rear pressure adjustment screw 1
4, respectively, by a predetermined distance from the tip. In this state, the pressure adjusting screw 14 and compression spring 13 do not apply any pressure force between the front surface of the gear portion 15b of the click metal 15, the washer 16 in front of it, the compression spring 13, and the washer 22 behind it, and the spool shaft 12 free rotations are now possible.

In order to brake the spool shaft 12 in the above-mentioned condition, first tighten the drag adjustment knob 18 and gradually move the pressure adjustment screw 14 forward, and the compression spring 13 installed in the pressure adjustment screw 14 will move forward. Washers 17 and 21 are moved forward together. Along with this, each of the adjacent members 22, 13, 17, 21, 20, in which the coil spring 20 in contact with the front surface of the washer 21 is compressed,
A predetermined contact load is generated between 15 and 16, and thereby a resistance force (frictional force) against the rotational force of the spool shaft 12 acts. Therefore, if the amount of tightening of the pressure adjusting screw 14 is gradually increased in this state, a desired braking force can be applied to the rotating spool shaft 12.

When the drag adjustment knob 18 is tightened to the maximum in this manner, as shown in FIG. Washiya 21,
Both the front and rear parts of 17 are made of click metal support tube 15
c and the tip of the pressure adjustment screw 14, and is made of a click metal gear part 15b.
The front surface is connected to the insertion part 11 via the front washer 16.
The inner step portion 11a is in close contact with the inner step portion 11a. Also, since the rear end of the compression sprig 13 is in close contact with the inner surface of the pressure adjustment screw 14 via the washer 22, the spool 12
Almost perfect braking against rotation can be expected.

Therefore, in this embodiment, the conventional method of stacking a large number of Teflon washers is not used;
By using a washer made of asbestos or the like having a large coefficient of friction as the washer 21, the adhesion between adjacent members can be increased and the fishing force of the reel can be significantly increased.

On the other hand, when the compression state of the drag adjustment knob 18 is loosened in order to switch to the drag-free state in the above-mentioned state, the pressure adjustment screw 14 is moved backward and the compression force applied to the compression sprig 13 is released. At the same time, due to the restoring elasticity of the coil spring 20 elastically installed in the hollow portion 15d of the click metal 15, the washers 21, 17 that are in close contact with the end of the support tube 15c are pushed rearward by the backward movement width of the pressure adjusting screw 14. Along with this, the support tube 15c and washer 21 of the click metal 15, which are in close contact with each other, are separated and returned to the state shown in FIG. The sticking phenomenon is completely eliminated and the spool shaft 12 and spool 23 can rotate smoothly.

e Effects of the invention As explained above, the drag system according to the invention has a simple structure in which a coil spring and an asbestos washer are provided between the click metal and the washer, which eliminates the phenomenon of sticking between the braking members and improves the drag system. Not only can the spool shaft rotate smoothly when it is free, but it also eliminates the need for expensive Teflon washers, greatly reducing the amount of washers required, reducing manufacturing costs and improving productivity. Moreover, there are advantages such as increasing the fishing force of the reel and increasing the reliability of the product.
