Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a spool support structure for a fishing spinning reel.

(Prior Art) Generally, the spool support in this type of spinning reel for fishing is fixedly held at a predetermined position at the front of the main shaft by a drag knob or the like.
The fishing line is wound around the spool by the back and forth movement of the spool and the flyer, which is equipped with a bail that rotates on the outside of the spool. The fishing line is wound flatly around the body of the spool due to the position of the line guide roller and the position of the spool which reciprocates back and forth. However, if the thickness (number) of the fishing line used for fishing is different, the winding position of the fishing line will shift, and the winding state will be biased towards the front or back of the body, resulting in a problem during use. This problem occurs when the fishing line collapses to the valley side where the amount of winding is small, causing the fishing line to become tangled.

Therefore, it is possible to adjust the reciprocating position of the spool relative to the line guide roller according to the thickness (number) of the fishing line used, thereby correcting the imbalance in the winding of the fishing line and making it flat. A spool position adjustment device for this purpose has been researched and developed.

A conventional example of the spool position adjusting device is Japanese Utility Model Publication No. 54-3108. This conventional structure utilizes a structure in which the spool is clamped and held by a click gear fixed to the main shaft and a drag knob screwed into the threaded rod at the tip of the main shaft, and the position of the click gear relative to the main shaft is aligned with the axis. The spool can be moved back and forth along the spool, thereby making it possible to adjust the mounting position of the spool in the back and forth direction.

However, in the conventional structure described above, in order to adjust the position of the spool, the spool must be removed from the main shaft and the click gear fixed and locked to the main shaft must be moved. However, the disadvantage is that adjusting the position of the spool requires a lot of effort and is difficult to operate.

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention aims to make it possible to easily adjust the position of the spool from the outside without disassembling the reel.

(Means for Solving the Problems) The technical means of the present invention for solving the above problems is to rotatably fit a drag case to the front part of the main shaft, and install a plurality of drags in the case. The spool accommodates the washer and applies frictional force to the rotation of the drag case relative to the main shaft, and the spool is fitted to the outside of the drag case so as to be slidable up and down. The spool is provided with an inclined surface and a protrusion having a height difference along the circumferential direction, and the spool is elastically biased by a spring in the direction in which it collides with the flange. to perform the rotation stop function.

The above-mentioned inclined surface has a height difference along one circumference, and its surface is made into a chevron-shaped or square-shaped uneven surface, etc., so that the position of the protrusion that abuts against the surface of the inclined surface does not change.

(Operation) The spool, which is pressed in the direction of colliding with the flange of the drag case by the elastic force of the spring, is pulled upward against the elastic force of the spring to release the engagement between the inclined surface and the protrusion. In this state, if you rotate the spool in the circumferential direction and release the pull-up of the spool at the desired position, the spool will be biased in the direction of colliding with the flange due to the elastic force of the spring, and the spool will be lower than the position before adjustment. Adjustable to move forward and backward.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. A click gear 2 is fixed to a small diameter stepped portion at the front of the main shaft 1, and the main shaft 1 ahead of the click gear 2 A cylindrical drag case 3 is rotatably fitted to the
A spool 4 is fitted to the outside of the drag case 3 so as to be vertically slidable.

The drag case 3 has a circular recess 5 in the upper half.
is formed, and a plurality of drag washers 6 are housed in the recess 5, and a flange 7 protruding outward in the radial direction is provided at the bottom of the drag case so as to face the bottom surface of the spool 4. There is.

The spool 4 fitted on the outside of the drag case 3 has a large diameter hole 8 formed inside thereof, and forms a space 10 containing a spring 9 between the spool 4 and the outer peripheral surface of the drag case 3, and facing the flange 7 on the bottom surface. A protrusion 11 is protrudingly provided at the position, and the base of a click pawl 13 is fixed with a set screw 14 to a mounting leg 12 protruding outward from the protrusion 11, and the tip thereof is connected to the click gear 2. They are designed to mesh together.

The upper surface of the flange 7 with which the protrusion 11 at the bottom of the spool 4 abuts is formed into an inclined surface 15 whose height increases sequentially along the circumferential direction, and the surface of the inclined surface 15 has a chevron-shaped cross section. The tip of 11 is formed into a chevron shape that engages with the chevron-shaped surface of the inclined surface 15.

The slope 15 formed on the surface of the flange 7 in the drag case 3 and the protrusion 1 on the bottom of the spool 4
The meshing structure with 1 is not limited to the above-mentioned chevron-shaped cross section, but may be as shown in FIG. 6. That is, in FIG. 6, the tip end surface of the protrusion 11 on the spool 4 side is a flat surface, and recesses 16 into which the protrusion 11 fits are formed at equal intervals on the inclined surface 15.

In the figure, 17 is a drag knob, and 18 is a spring holding nut, which is screwed onto the outer side of the upper end of the drag case 3 to force the spring 9 to be accommodated in the space 10.

To explain the position adjustment operation of the spool configured as above, first, the protrusion 11 of the spool 4
When moving the spool 4 forward from the state shown in FIG. When the part 11 is disengaged from the inclined surface 15 and the spool 4 is rotated clockwise (rightward) to release the lifting force of the spool 4 at the desired position, the spool 4 is lifted by the elastic force of the spring 9. The protrusion 11 is pressed toward the flange 7 and engages with the inclined surface 15 again to stop the rotation of the spool 4, and the spool 4 is adjusted to move forward as shown in FIG.

With the above structure, the drag case 3 and the spool 4 are engaged and integrated, and when a fish is caught on the fishing line (tackle) wound around the spool 4 and a force is applied in the direction of letting out the fishing line, the tension of the fishing line is reduced to the drag. When the friction force is greater than the friction force generated by pressing the drag shear 6, the drag case 3 and spool 4 rotate freely relative to the main shaft 1 as a unit, the fishing line is let out, and the drag mechanism is activated.
Of course, when the tension of the fishing line is smaller than the frictional force between the main shaft 1 and the drag case 3, the fishing line is wound onto the spool 4 by rotation of the handle. Further, the drag mechanism described above operates in the same manner even when the spool 4 is moved vertically with respect to the drag case 3.

(Effect of the invention) Since the spool support structure of the present invention has the configuration as described in detail above, the spool can be pulled up against the elastic force of the spring and rotated clockwise or counterclockwise at a desired angle. The position of the spool can be adjusted back and forth by moving it and releasing the pulling force.

In other words, there is no inconvenient operation such as disassembling the reel form and manipulating the internal structure, and it can be done simply by operating the spool from the outside while the reel form is in place, so if there is a change in the winding of the fishing line, it can be done quickly. You can adjust and deal with it.
