Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool attaching / detaching mechanism for a fishing spinning reel.

[0002]

2. Description of the Related Art Japanese Patent Laying-Open No. 7-213201 discloses a spool attaching / detaching mechanism in a fishing spinning reel (hereinafter referred to as "prior art 1").

[0003] In the prior art 1, the fishing spinning reel has a brake cylinder rotatably mounted on a spool shaft which is reciprocally slidable in the front-rear direction, which is stopped from rotating. Is stopped and held. A male screw is provided at the front portion of the spool shaft, and a pressing body is screwed into the male screw. A braking element is interposed between the pressing body and the brake cylinder, and the braking element and the brake cylinder are connected to the pressing body and the spool. It is sandwiched between the stopper on the shaft. In addition, a drag knob for turning the pressing body around the spool shaft is rotatably provided. Further, a locking member made of a ring-shaped spring is detachably attached to the tip of the spool shaft, and the drag knob and the spool are sandwiched between the locking member and the brake cylinder from the front and rear. Thus, by rotating the drag knob, the pressing body can be rotated to increase or decrease the braking force of the braking element on the brake cylinder.

[0004] The tip of a push button placed on the tip of the spool shaft comes into contact with the above-mentioned locking tool. If the push button is pushed in against the spring force of the locking tool, the locking tool is pushed out by the tip of the push button and separated from the spool shaft. Thereby, the spool can be pulled out from the spool shaft.

Japanese Patent Application Laid-Open No. Hei 9-119 also discloses a spool attaching / detaching mechanism in a fishing spinning reel (hereinafter referred to as "prior art 2").

In the prior art 2, a fixed drag body is fitted around the outer periphery of the spool shaft, and a rotary drag body is rotatably fitted around the fitted portion of the fixed drag body. A drag washer is interposed between the resistance plates of the drag body, an elastic body is arranged between the rotary drag body and the drag knob, and a spool is screwed to the outer periphery of the rotary drag body. Here, the inner diameter of the spool is configured to be larger than the outer diameter of the drag knob, and the spool can be removed without removing the drag knob.

[0007]

However, in the prior art 1, the operation of detaching the locking tool from the spool shaft or the spool receiver is regarded as simply pressing the push button. For this reason, when the hand holding the spool hits the push button by mistake during the feeding or winding operation of the fishing line, the spool, the drag knob or the like may fall off the spool shaft.

On the other hand, in the prior art 2, in order to remove the spool, it is necessary to first tighten the drag knob sufficiently. More specifically, in order to release the screwing between the rotary drag body and the spool, the fixed drag body is pressed with a force larger than the force required to release these screwing prior to rotating the spool. It is necessary to maximize the braking force by the drag mechanism, that is, the frictional resistance between the fixed drag body and the rotary drag body so that the rotary drag body is pressed and held. Therefore, when the spool is mounted again, it is necessary to adjust the braking force again.

An object of the present invention is to prevent the spool, the drag knob and the like from dropping off the spool shaft even if the hand gripping the spool accidentally hits the drag knob side during the operation of feeding or winding the fishing line, and re-attaching the spool. It is an object of the present invention to provide a fishing spinning reel spool attachment / detachment mechanism that does not need to adjust the braking force again.

The drag knob 8 is provided rotatably around the spool receiver 2 so as to turn the pressing body 6 to increase or decrease the braking force of the braking element 7 on the spool 3.

In the spinning reel having the above-described basic configuration, the spool attaching / detaching mechanism A of the present invention is characterized in that the locking tool 5 is disposed in the recess 8a provided in the drag knob 8, and the locking tool 5 does not come loose. As described above, the front side of the spool shaft is covered with the drag knob 8.

The structure of the drag knob 8 and its peripheral portion will be described in detail below. As shown in FIG. 4, the drag knob 8 has a concave portion 8a which is opened rearward at a central portion thereof. The bottom of the concave portion 8a is constituted by a part of the arch-shaped portion 8b. Except for the arch-shaped portion 8b, the concave portion 8a is open forward.
At the center of the inner surface of the arch-shaped portion 8b, a projection receiver 8c for the projection 5a provided at the tip of the locking tool 5 is formed.

The locking tool 5 is inserted into the recess 8a of the drag knob 8 such that the projection 5a is housed in the projection receiver 8c. As described above, the recess 8a of the drag knob 8 is also opened forward except for the arch-shaped portion 8b. Therefore, as shown in FIG. 3, a part of the locking tool 5 inserted into the recess 8 a is exposed at the tip side of the drag knob 8. It becomes possible from the side.

At the rear end of the drag knob 8, a support plate 17 having a similar oval insertion hole 17 a matching the oval cross section at the tip of the spool shaft 1 is rotatably disposed with respect to the drag knob 8. Is done. An O-ring 18 is disposed between the support plate 17 and the locking device 5 so as to prevent the locking device 5 from loosening.

As shown in FIG. 4, the support plate 17 is rotatably held by a drag nut holder 19 whose tip is fixed to the drag knob 8 by a screw 22. The inside of the rear end of the drag nut holder 19 is fitted with the pressing body 6 as a drag nut so that the pressing body 6 can be operated.
It has a hexagonal shape that matches its outer diameter.

Accordingly, the drag nut holder 19 rotatably holds the support plate 17 on the drag knob 8, and the support plate 17 thus held rotatably holds the locking member 5.

On the outer periphery of the drag nut holder 19,
A waterproof ring 20 is provided. This waterproof ring 20
Contacts the inner peripheral surface of the spool ring retainer 16 described above to maintain the airtightness between the drag nut holder 19 and the spool ring retainer 16.

In FIG. 4, a click mechanism 21 incorporated in the lower portion of the drag knob 8 is urged by a spring so as to protrude toward the rear end of the drag knob 8, The support plate 17 is resiliently engaged with a recess formed in the front surface of the support plate 17 at circumferential intervals. Thus, when the drag knob 8 is rotated, a slight vibration and a click sound are generated, and the adjustment of the braking force by the braking element 7 is tactually and audibly confirmed.

As shown in FIG. 4, the locking unit 5, the drag knob 8, the support plate 17, the drag nut holder 19, the waterproof ring 20, and the click mechanism 21 are combined with each other to form an adjustment unit as a single assembly. Configure the AU.

In order to mount the spool unit SU and the adjustment unit AU on the spool shaft 1, the spool shaft 1 is installed in the spool receiver 2 of the spool unit SU.
And the stopper 4 fixed to the spool shaft 1 is housed in the groove 2a of the spool receiver 2.

Next, the tip of the spool shaft 1 is inserted into the insertion hole 17a of the support plate 17 of the adjustment unit AU, and further inserted into the female screw of the locking member 5. In this state, the locking tool 5 exposed on both sides of the arched portion 8b from the distal end side of the drag knob 8 is rotated clockwise and screwed to the spool shaft 1. In this state, the support plate 17
Insertion hole 17a has a similar oval shape that matches the oval cross section at the tip of the spool shaft 1.
The support plate 17 is held so as not to rotate with respect to the spool shaft 1.

When the drag knob 8 is rotated clockwise in this state, the drag nut holder 19 operably receives the pressing body 6, so that the pressing body 6 also rotates clockwise, causing the drag spring 14 to rotate. As a result, the braking force by the braking element 7 increases. If the drag knob 8 is rotated in the counterclockwise direction, the braking force is reduced, contrary to the above operation.

After the adjustment of the braking force by the braking element 7 is performed, when the spool 3 is to be removed for maintenance or replacement, when the spool 3 is to be removed, the both ends of the drag knob 8 with the arch-shaped portion 8b interposed therebetween. Is rotated counterclockwise to release the screw engagement with the spool shaft 1, pull out the adjusting unit AU from the spool shaft 1, and further pull the spool unit SU from the spool shaft 1. You only have to get out.

At this time, even if the adjusting unit AU is pulled out, the screwing state of the pressing body 6 to the spool receiver 2 does not change in the spool unit SU, in other words, the braking force adjusted as described above. Is still properly maintained. Therefore, in the procedure described above,
The spool unit SU and the adjustment unit AU may be attached to the spool shaft 1, and there is no need to readjust the braking force.

Since the arch-shaped portion 8a of the drag knob 8 prevents inadvertent rotation of the locking member 5, the drag knob 8, the spool 3 and the like do not accidentally fall off as in the prior art 1.

Next, a spool attaching / detaching mechanism B of a fishing spinning reel according to a second embodiment of the present invention will be described in detail with reference to FIGS.

Spool attaching / detaching mechanism B according to the second embodiment
Is the same as the spool attachment / detachment mechanism A according to the first embodiment, except that the locking member 23 is easily detachably attached to the distal end portion of the spool shaft 1 by rotating at a rotation angle of several tens degrees. It is. Therefore, the same components are denoted by the same reference numerals, and description thereof will be omitted.

In this state, the locking tools 23 exposed on both sides of the arched portion 8b from the tip side of the drag knob 8 are rotated clockwise to move the projection 1b of the spool shaft 1 in the inclined portion 24b of the guide groove 24. And further, it is engaged in the engaging portion 24c. In this state, since the insertion hole 17a of the support plate 17 has the same oval shape that matches the oval cross section at the tip of the spool shaft 1, the support plate 17 rotates with respect to the spool shaft 1. It is kept in an impossible state.

When the drag knob 8 is rotated clockwise in this state, the drag nut holder 19 operably receives the pressing body 6, so that the pressing body 6 also rotates clockwise, causing the drag spring 14 to rotate. As a result, the braking force by the braking element 7 increases. If the drag knob 8 is rotated in the counterclockwise direction, the braking force is reduced, contrary to the above operation.

After the braking force has been adjusted by the braking element 7, when the spool 3 is to be removed for maintenance or replacement, the spool knob 3 can be removed from both ends with the arch-shaped portion 8 b sandwiched from the tip end of the drag knob 8. Locking tool 23 exposed on
Is rotated counterclockwise to disengage the projection 1b of the spool shaft 1 from the guide groove 24, pull out the adjusting unit AU from the spool shaft 1, and further pull out the spool unit SU from the spool shaft 1. Good.

At this time, even if the adjusting unit AU is pulled out, the threaded state of the pressing body 6 with respect to the spool receiver 2 does not change in the spool unit SU, in other words, the braking force adjusted as described above. Is still properly maintained. Therefore, in the procedure described above,
The spool unit SU and the adjustment unit AU may be attached to the spool shaft 1, and there is no need to readjust the braking force.

The arch-shaped portion 8a of the drag knob 8 prevents the locking member 23 from being inadvertently rotated, so that the drag knob 8, the spool 3 and the like do not accidentally fall off as in the prior art 1.

Spool attachment / detachment mechanism B according to the second embodiment
Also, the O-ring 18 disposed between the support plate 17 and the locking member 23 applies a force acting to push the locking member 23 to the outside. Looseness is prevented.

In the first and second embodiments of the present invention,
Although the drag knob 8 has been described as having the arch-shaped portion 8a, the locking tool 5 or 23 is provided at the tip side of the drag knob 8.
A part of the drag knob 8 that conceals a part of the locking tool 5 or 23 is not limited to the arch shape, and may have any shape.

In the second embodiment of the present invention, the locking device 2
3, a pair of guide grooves 24 is formed at a position facing the peripheral wall, and a protrusion 1 b capable of engaging with the pair of guide grooves 24 of the locking member 23 is provided at the tip of the spool shaft 1. Alternatively, a projection may be provided on the peripheral wall of the locking member 23, and a guide groove may be formed at the tip of the spool shaft 1.
