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 having the above-mentioned structure, the trouble of replacing the drag washer can be eliminated, but when replacing the spool, the spool is screwed into the rotating drag body. When the set drag force is weaker than the force, when the spool is rotated in the direction to remove it, the rotating drag body rotates with respect to the fixed drag body as the spool rotates, causing the spool to idle. And the spool cannot be removed. That is, the spool cannot be removed unless the drag force is larger than the tightening force with which the spool is screwed into the rotating drag body.Therefore, every time the spool is replaced, the drag knob should be fully tightened to remove the spool. I had to adjust the setting of the drag force after installing a different spool, and it took time to start fishing again.

The present invention has been made in order to solve the problems of the above-mentioned prior art, and the purpose thereof is to allow the spool to be replaced without removing the drag knob and to set the spool. An object of the present invention is to provide a support structure for a spinning reel that can hold the drag force and change the spool.

[0008]

A tubular fixed drag body is fixed to the outer periphery of a spool shaft that moves back and forth by the rotation of a handle, and the tubular rotary drag body is freely rotatable in the axial direction. And a removable disk-shaped resistance plate is integrally formed on both ends of the drag body, and a drag washer is inserted between the resistance plates to form a drag body. A spring is elastically mounted between the tip of the rotary drag body and a drag knob screwed to the tip of the spool shaft, and a spool with a through hole formed in the axial direction is removable on the outer periphery of the rotary drag body in the drag body. The minimum diameter of the through hole in the spool, which is screwed, is larger than the maximum diameter of the drag knob. When the rotation of the rotary drag body rotates in the direction to disengage the spool from the rotary drag body, the rotary drag body is locked to the fixed drag body, and the rotation of the rotary drag body changes the spool to the rotary drag body. The rotating drag body is provided with a reverse rotation preventing mechanism configured to rotate relative to the fixed drag body when rotating in the tightening direction. The reverse rotation prevention mechanism locks the rotary drag body to the fixed drag body and rotates the spool to the rotary drag body when the rotation of the rotary drag body rotates in the direction of removing the spool from the rotary drag body with respect to the fixed drag body. The rotating drag body may be a mechanism that rotates with respect to the fixed drag body when rotating in the tightening direction, and specifically, it can be achieved by means such as a ratchet mechanism or a one-way clutch. In the ratchet mechanism, the resistance plate of the rotary drag body is integrally formed with a cylinder body coaxial with the resistance plate of the rotary drag body on the surface facing the resistance plate of the fixed drag body. The diameter is set to be slightly larger than the diameter of the fixed drag body, and an axial concavo-convex portion that is continuous along the circumferential direction of the cylinder is formed at the end of this tubular body, while the concavo-convex portion is formed on the resistance plate of the fixed drag body. An elongated plate-like engaging plate that is engaged with and disengages from the concave portion to restrict rotation of the rotary drag member is attached. The engaging plate is rotatable about the axial direction, and one end portion of the engaging plate is always engaged with the engaging concave portion. It is biased so as to be aligned, and the other end is brought into contact with the convex portion provided on the resistance plate to regulate the rotation of the engagement plate. Further, an inclined surface that inclines from the tip edge toward the inner circumference is formed on the inner peripheral surface of the convex portion of the uneven portion that constitutes a part of the ratchet mechanism, and the base end portion of this inclined surface is the engagement plate. Was positioned outside the tip of the. The reverse rotation prevention mechanism is a one-way clutch,
The directional clutch is inserted between the outer peripheral surface of the tubular portion of the fixed drag body and the inner peripheral surface of the tubular portion of the rotary drag body, and the one-way clutch rotates integrally with the rotary drag body, and is removable and fixed drag. It is removable from the body.

According to the above means, when the drag force is adjusted by rotating the drag knob screwed to the spool tip, the spring elastically mounted between the drag knob and the rotary drag body in the drag body changes the biasing force. While moving, the drag force is adjusted by the biasing force of this spring. When replacing the spool, if the spool is rotated in a direction to loosen the screw engagement with the rotary drag body, the reverse drag mechanism locks the rotary drag body to the fixed drag body. Therefore, even if the spool is set in a state in which the drag force is weaker than the tightening force for the rotating drag body, the spool is disengaged from the rotating drag body without spinning. When installing, reverse the above removal work.

When exchanging the drag washer, the drag adjusting body screwed to the spool shaft is rotated in the direction of weak drag force, removed from the spool shaft, and pulled out in the order of the rotating drag body. It is exposed and can be replaced. After assembling the drag washers, when assembling, the above-mentioned work may be reversed. The above-described work of replacing the spool and the drag washer can be performed by the same work method, whether the reverse rotation preventing mechanism is a ratchet mechanism or a one-way clutch. Also, in the case where the ratchet mechanism is used as the reverse rotation prevention mechanism, when the rotating drag body is attached to the fixed drag body, the inner peripheral surface of the convex portion of the uneven portion forming the ratchet mechanism formed in the cylindrical body of the fixed drag body is an inclined surface. age,
Since the base of this inclined surface is located outside the tip of the engagement plate, even if the tip position of the engagement plate of the ratchet mechanism does not align with the recess of the ratchet mechanism, the tip of the engagement plate will not contact the end face of the cylinder. It is guided along the inclined surface of the convex portion of the ratchet mechanism without contact. Also, in the case where the reverse rotation prevention mechanism is a one-way clutch, the reverse rotation prevention mechanism is a single assembly, so that the structure of the reel itself is simplified.

When the rotation of the drag body 3 rotates in the direction in which the spool is tightened on the rotary drag body 3, the rotary drag body 3 rotates with respect to the fixed drag body 2 and is equipped with a ratchet mechanism R that constitutes a reverse rotation prevention mechanism. Therefore, the rotation of the rotary drag body 2 is restricted.

The fixed drag body 2 is fixed in a radial direction from the outer peripheral surface of the tubular portion 2B to the spool shaft 1 by passing through a pin P in a direction perpendicular to the axial direction and having a pin P penetrating the tubular portion 2B. An engaging plate R1 forming a part of the ratchet mechanism R is attached to the tip surface of the resistance plate 2A. The engagement plate R1 is formed in a long piece shape having a circular mounting hole R1-1 formed at the center, and one end of the engagement plate R1 is substantially rectangular and the other end is tapered toward the end. Further, a cylindrical body R1-2 having the same inner diameter as the diameter of the mounting hole R1-1 is formed integrally with the mounting hole R1-1 on the coaxial line. Then, a screw B or the like is passed through a mounting hole of the engagement plate R1 and attached to the resistance plate 2A of the fixed drag body 2 so as to rotate about the axial direction of the drag body D.

The other end of the engaging plate R1 is brought into contact with the convex portion 2A-1 provided on the resistance plate 2A to regulate the rotation of the engaging plate R1.

In the rotary drag body 3, a threaded portion 3C is provided on the outer circumference of a cylindrical portion 3B, a sleeve 6 is inserted on the inner peripheral surface, and a washer 3D is inserted. This washer 3D is the tip of the fixed drag body 2. A cylindrical body 3E having the same diameter as that of the resistance plate 3A is integrally formed on the resistance plate 3A so that the resistance plate 3A is non-rotatably and slidably engaged, and the inner diameter of the cylinder body 3E is fixed. The diameter of the resistance plate 2A is slightly larger than that of the resistance plate 2A, and is formed so as to cover the resistance plate 2A of the fixed drag body 2. A part of the ratchet mechanism R is formed on the peripheral surface of the end of the cylindrical body 3E. The engaging portion R2 is provided. or,
The drag washer W is pressed by the resistance plate 3A of the rotary drag body 3 provided facing the resistance plate 2A of the fixed drag body 2. The engaging portion R2 forms concavo-convex portions R2-1 and R2-2 that are continuous along the peripheral side surface of the cylindrical body 3E, and the convex portions R2-2 in the concavo-convex portions R2-1 and R2-2.
The front end of the inclined surface R2-3 is inclined toward the inner circumference, and the base of the inclined surface R2-3 is located outside the front end of the engaging plate R1.

The ratchet mechanism R for restricting the rotation of the rotary drag body 2 rotates the rotary drag body 3 by engaging and disengaging the engaging plate R2 of the fixed drag body with the engaging portion R1 of the rotary drag body 3 described above. When the rotation of the rotary drag body 3 rotates in the direction to remove the spool 5 from the rotary drag body 3, the rotary drag body 3 is locked by the fixed drag body 2 and the rotary drag body 3 is locked. The rotating drag body 3 rotates with respect to the fixed drag body 2 when the spool rotates in the direction in which the spool 5 is fastened to the rotating drag body 3.

The drag knob 4 screwed onto the spool shaft 1 is formed in a tubular shape, and the rotation of the drag knob 4 causes the rotary drag body 3 to move in the axial direction of the fixed drag body 2. Further, a groove 4B is provided so as to surround the screw hole 4A from the rear end surface of the drag knob 4 in the axial direction, and the drag spring S is inserted in the groove 4B. The drag spring S includes the groove portion 4A of the drag knob 4 and the washer 3 of the rotary drag body 3 described above.
It is elastically mounted between D and D, and pushes the rotary drag body 2 by moving the drag knob 4. It should be noted that the drag spring S is not limited to the coil spring, but the rotary drag body 3 can be moved by moving the drag knob 4.
Any material may be used as long as the pressing force for pressing can be varied.

The spool 5 screwed onto the drag body D is
The minimum inner diameter of the through hole 6A is formed to be larger than the maximum diameter of the drag knob 4 described above, and the threaded portion 5B is provided on the inner circumference of the minimum inner diameter portion so as to be detachable from the drag body D. . Further, a ring-shaped base 4C is applied to the front surface of the spool 5, and the outer peripheral edge of the base 4C is rotatably held and retained by a ring-shaped retainer 5C screwed onto the front surface of the spool 5. It is attached so as to rotate freely, and is structured so as not to hinder the rotation of the drag knob 4. On the front surface of the base 4C, two guard plates 4D that draw an arc continuous to the spherical surface of the tip of the drag knob 4 are projected toward the tip, and the two guard plates 4D facing each other with the drag knob 4 interposed therebetween are provided. , Drag knob 4
It prevents the fishing line from getting entangled. Also, the above-mentioned base 4C
The inner diameter of the base is slightly larger than the outer diameter of the drag knob 4, so that the base 4C can be freely inserted and removed together with the spool 5.

To replace the spool 5 in the spinning reel constructed as described above, the spool 56 can be rotated and unscrewed from the rotary drag body 3 to be pulled out in the axial direction. (Fig. 4) At this time, the rotating drag body 3
Is locked to the fixed drag body 2 by the ratchet mechanism R. Next, the spool to be replaced is screwed into the rotary drag body 3 and attached.

When the drag washer W is replaced, when the drag knob 4 is rotated in the direction in which the drag force is weak, the drag knob 4 screwed on the spool shaft 1 is disengaged from the spool shaft 1 and the rotary drag body is rotated. Since 3 is screwed to the spool 5, it is pulled out integrally with the spool 5, and the drag washer W is exposed and is in a replaceable state. (FIG. 3) When the drag washer W is replaced and then assembled, the above operation may be performed in reverse. At this time, the tip of the engaging plate R1 of the ratchet mechanism R is not aligned with the recess R2-1 of the ratchet mechanism R. Even if the engaging plate R1

It is inserted between the inner peripheral surface of the portion 3B. The one-way clutch 7 is oval-engaged in the rotary drag body 3 so as to be detachably fitted therein so as to rotate integrally with the rotary drag body 3 and to be put in and taken out through an opening portion of the rotary drag body 3. or,
The fixed drag body 2 can be inserted and removed in the axial direction. The one-way clutch 7 has a function of preventing reverse rotation of the one-way clutch 7 acting on the fixed drag body 2 when the rotation of the rotary drag body 3 rotates in a direction to remove the spool 5 from the rotary drag body 3. 3 is locked by the fixed drag body 2, and the rotation of the rotating drag body 3 is caused by the spool 5
When rotating in the direction to tighten the rotation drag body 3,
The rotating drag body 3 is adapted to rotate with respect to the fixed drag body 2. A ratchet r is provided across the resistance plate 2A of the fixed drag body 2 and the resistance plate 3A of the rotary drag body 3 so as to impart a moderation to the rotation of the spool 5 and generate a click sound.

[0021]

The present invention has the following effects due to the above configuration. Even if the drag knob is not removed, the spool can be replaced by unscrewing the spool, so the drag knob will not be lost when the spool is replaced. Also, since the spool can be replaced while the set drag force is maintained by the action of the reverse rotation prevention mechanism, the trouble of resetting the drag force each time the spool is replaced can be eliminated. Further, in the case where the reverse rotation preventing mechanism is a ratchet mechanism, even when the tip end position of the engaging plate of the ratchet mechanism does not match the recess of the ratchet mechanism when the rotating drag body is attached to the fixed drag body,
Since the tip of the engagement plate is guided along the inclined surface of the convex portion of the ratchet mechanism without contacting the end surface of the cylindrical body, the rotary drag body can be smoothly fitted into the fixed drag body. Even if the reverse rotation prevention mechanism is a one-way clutch, the same effect as that of a ratchet mechanism can be obtained. Further, even if the one-way clutch fails, the one-way clutch itself can be replaced, and the immediate effect can be obtained.
