Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool support structure for a spinning reel having a front drag mechanism.

[0002]

2. Description of the Related Art Conventionally, a structure shown in FIG. 5 is generally known as a spool supporting structure in a spinning reel having a front drag mechanism. The structure is such that a recess 103 is formed in the front surface of a spool 102 that is rotatably and detachably attached to a spool shaft 101.
A multi-plate drag washer 104 is housed in 03, and the drag washer 104 is retained by a clip ring 105 attached to the peripheral surface of the recess 103. Further, a drag knob 106 is screwed onto the tip of the spool shaft 101, and by rotating the drag knob 106, the drag washer 104 is pressed to change the drag force, or the spool 102 is detached and the spool 102 is detached. Has become.

By the way, since the drag mechanism exerts a drag force by friction of the drag washer, the drag washer wears during use and the drag force stops working. Therefore, it is possible to replace a worn drag washer. When replacing the drag washer in the above conventional spinning reel, remove the drag knob from the spool shaft,
The clip washer that holds the drag washer stored on the spool is removed, and the drag washer is replaced. However, the work of removing the clip ring is very troublesome because it must be done carefully using a special tool so as not to lose or break the clip ring. Further, when the spool is replaced, the spool cannot be replaced unless the drag knob is removed, so there is a risk that the drag knob may be accidentally lost when performing the replacement work on a rocky place or on a ship.

The present applicant has developed a spinning reel shown in FIG. 6 in order to solve the above drawbacks. In this structure, a cylindrical fixed drag body 202 is fixed to a spool shaft 201 that moves back and forth by the rotation of a handle, and a cylindrical rotary drag body 203 is freely rotatable and axially slidable on the fixed drag body 202. Mounted on the resistance plate 204 facing the ends of the drag bodies 202, 203.
205 is integrally provided, a drag washer 206 is inserted between the resistance plates 204, 205, and a cylindrical drag knob 207 is screwed onto the tip of the spool shaft 201 to rotate with the drag knob 207. A spring 208 is elastically mounted between the ends of the drag body 203, and a spool 209 having a through hole formed in the axial direction is detachably screwed onto the rotary drag body 203, and the minimum diameter of the through hole in the spool 209 is dragged. It is configured to be larger than the maximum diameter of the knob 207.

According to the spinning reel having the above structure, when the drag washer is replaced, the rotary drag body having the spool screwed thereon is slidably attached to the fixed drag body, and the drag washer is mounted between the drag bodies. Therefore, if you rotate the drag knob to remove the drag adjustment body from the spool shaft and pull out the spool, the rotary drag body is pulled out integrally with the spool, which exposes the drag washer and allows you to easily replace the drag washer. I was able to do it. Also, when replacing the spool, the spool is screwed into the rotating drag body, so that it is possible to remove only the spool by tightening the drag knob sufficiently and rotating the spool. Can be prevented.

[0006]

However, in the spinning reel configured as described above, it is possible to eliminate the trouble of exchanging the drag washer, but since the drag knob has to be removed, the drop of the drag knob occurs when exchanging the drag washer. The problem of loss has occurred. Furthermore, since the diameter of the drag knob screwed onto the tip of the spool shaft is smaller than the minimum diameter of the through hole in the spool, when the reel becomes smaller, the drag knob becomes smaller accordingly, and when adjusting the drag force. There was a new operational problem that the drag knob was difficult to turn. Also, the spool is attached to the rotating drag body by screwing, so when removing the spool, the drag knob should be tightened sufficiently and the rotating drag body should rotate with respect to the fixed drag body unless the drag force is maximized. As a result, the spool becomes idle and the spool cannot be removed. That is, the drag force must be set every time the spool is replaced, and it takes time to start fishing again.

The present invention has been made in order to solve the problems of the above-mentioned prior art. The object of the present invention is to enable replacement of the drag washer and spool without removing the drag knob. Even if the reel becomes small, you can easily adjust the drag force.
It is to provide a supporting structure for a spinning reel that can hold a set drag force and change the spool with one touch.

[0008]

An annular locking recess is formed at the tip of a spool shaft that is moved back and forth by the rotation of a handle to fix a cylindrical fixed drag body, and to rotate the cylindrical fixed drag body on the fixed drag body. The drag body is attached so as to be freely rotatable and slidable in the axial direction. An engaging portion is formed along the axial direction on the outer circumference of the rotary drag body, and a resistance plate facing both ends of the drag body is integrally formed. And a drag washer is inserted between the resistance plates to form a drag body, and a drag adjustment body having a non-circular cross section and a tubular shape is screwed into the tip of the spool shaft and rotated with the drag adjustment body. A spool in which a spring is elastically mounted between the ends of the drag body to form a through hole in the drag body in the axial direction, and an engaging portion that engages with an engaging portion of the rotary drag body is formed in the through hole. In addition to being detachably mounted, a drag knob that has a through hole in the axial direction on the spool tip surface is freely rotatable and attached so that the drag knob is at least larger than the minimum diameter of the through hole. Has a non-circular engagement recess that engages with the drag knob in a disengageable manner, and has a bottom surface of the engagement recess that is formed by parallel linear rods that engage with the engagement recess of the spool. A ring spring having a ring portion is attached so that the sandwiching portion can be expanded outward in the radial direction, and an expanding cylinder for expanding the sandwiching portion of the ring spring is inserted through a through hole in the drag knob. Further, the minimum diameter of the through hole in the spool is made larger than the maximum diameter of the drag adjusting body.

According to the above-mentioned means, when the drag force is adjusted, when the drag knob of the spool engaged with and held by the rotating drag body is rotated, the drag adjusting body screwed to the spool shaft is detachable from the drag knob. Since it is engaged with, it rotates integrally and moves while varying the urging force of the spring elastically mounted between this drag adjusting body and the rotating drag body in the drag body, and the urging force of this spring adjusts the drag force. Done. To replace the spool,
By pushing the expanding cylinder of the spool, the sandwiching portion provided on the ring spring is pushed and expanded, and it is disengaged from the hook recess of the spool shaft, so that the spool can be pulled out, and the spool can be replaced. When installing, by inserting the spool into the spool shaft, the sandwiching part provided on the ring spring is expanded by the conical part at the tip of the spool shaft, and when passing through the conical part, it is clamped in the retaining recess on the spool shaft. The parts are engaged to hold the spool on the spool shaft. When replacing the drag washer, rotate the drag adjustment body screwed to the spool shaft in the direction of weaker drag force, remove it from the spool shaft, and pull out the rotating drag body in order to expose and replace the drag washer. It will be possible. When installing after replacing the drag washer, the above procedure can be reversed. In any of the above-described spool replacement work and drag washer replacement work, the drag knob can be freely rotated with respect to the spool and is retained, so that the drag knob can be prevented from being lost. Also, the spool can be replaced while maintaining the drag force.

Further, since the drag knob has a diameter larger than the minimum diameter of the through hole of the spool, the drag knob does not become difficult to operate even if the reel becomes small.
