Spinning reel drag mechanism
A drag mechanism is arranged between a spool and a spool shaft and includes at least one first drag washer, at least one second drag washer and a drag knob. The at least one first drag washer has on an outer circumferential portion with at least one interlock protrusion. The at least one second drag washer is arranged with respect to the first drag washer along an axial direction of the spool. The drag knob is configured to be threaded onto the spool shaft to selectively adjust an amount of pressure acting on the first and second drag washers.
1. A spinning reel spool assembly comprising:
a spool having a drag housing recess formed in an internal circumferential surface of the spool, the drag housing recess having at least one interlock groove extending in a longitudinal direction of the spool, and a flange fastening member having a tubular section threaded into the drag housing recess; and
a spinning reel drag mechanism configured to brake a rotation of the spool and arranged between the spool and a spool shaft, the spinning reel drag mechanism including
at least one first drag washer having an outer circumferential portion with at least one interlock protrusion configured to engage with the interlock groove, the outer circumferential portion being free of an interlock protrusion at a section diametrically opposed to the at least one interlock protrusion, the at least one first drag washer being non-rotatable with respect to the spool in the drag housing recess and having an outside diameter that is smaller than an internal diameter of the tubular section of the flange fastening member.
at least one second drag washer configured to be arranged with respect to the first drag washer along the longitudinal direction of the spool, the at least one second drag washer being non-rotatable with respect to the spool shaft, the at least one second drag washer having an outside diameter that is smaller than an internal diameter of the tubular section of the flange fastening member, and
a drag knob configured and arranged to be threaded onto the spool shaft to selectively adjust an amount of pressure acting on the first and second drag washers,
the internal diameter of the tubular section being smaller than a maximum dimension of the at least one first drag washer, the maximum dimension being a length from an outermost edge of the at least one interlock protrusion to the outer circumferential portion at the section diametrically opposed to the at least one interlock protrusion.
2. The spinning reel spool assembly as recited in claim 1 , wherein
the outer circumferential portion has a plurality of interlock protrusions arranged within an angular phase of 90 degrees or less therebetween.
3. The spinning reel spool assembly as recited in claim 2 , further comprising
a seal member disposed between the drag knob and the first and second drag washers to prevent liquids from penetrating to the first and second drag washers.
4. The spinning reel spool assembly as recited in claim 2 , further comprising
one or more drag disks arranged between the first and second drag washers.
5. The spinning reel spool assembly as recited in claim 2 , further comprising
a retaining mechanism for retaining the at least one first and second drag washers inside the spool.
6. The spinning reel spool assembly as recited in claim 1 , further comprising
a seal member disposed between the drag knob and the first and second drag washers to prevent liquids from penetrating to the first and second drag washers.
7. The spinning reel spool assembly as recited in claim 1 , further comprising
one or more drag disks arranged between the first and second drag washers.
8. The spinning reel spool assembly as recited in claim 1 , further comprising
a retaining mechanism for retaining the at least one first and second drag washers inside the spool.
9. A spinning reel comprising:
a handle;
a reel unit rotatively supporting the handle;
a rotor rotatively supported on a front of the reel unit;
a spool disposed at a front of the rotor and having a drag housing recess formed in an internal circumferential surface of the spool, the drag housing recess having at least one interlock groove extending in a longitudinal direction of the spool, and a flange fastening member having a tubular section threaded into the drag housing recess;
a spool shaft disposed generally parallel to the longitudinal direction of the spool; and
a spinning reel drag mechanism configured to brake a rotation of the spool and arranged between the spool and the spool shaft, the spinning reel drag mechanism including
at least one first drag washer having an outer circumferential portion with at least one interlock protrusion configured to engage with the interlock groove, the outer circumferential portion being free of an interlock protrusion at a section diametrically opposed to the at least one interlock protrusion, the at least one first drag washer being non-rotatable with respect to the spool in the drag housing recess and having an outside diameter that is smaller than an internal diameter of the tubular section of the flange fastening member,
at least one second drag washer configured to be arranged with respect to the first drag washer along the longitudinal direction of the spool, the at least one second drag washer being non-rotatable with respect to the spool shaft, the at least one second drag washer having an outside diameter that is smaller than an internal diameter of the tubular section of the flange fastening member, and
a drag knob threaded onto the spool shaft to selectively adjust an amount of pressure acting on the first and second drag washers,
the internal diameter of the tubular section being smaller than a maximum dimension of the at least one first drag washer, the maximum dimension being a length from an outermost edge of the at least one interlock protrusion to the outer circumferential portion at the section diametrically opposed to the at least one interlock protrusion.
10. The spinning reel drag mechanism as recited in claim 9 , wherein
the outer circumferential portion has a plurality of interlock protrusions arranged within an angular phase of 90 degrees or less therebetween.
11. The spinning reel as recited in claim 10 , further comprising
a seal member arranged between the drag knob and the flange fastening member to prevent liquids from penetrating to the first and second drag washers.
12. The spinning reel as recited in claim 10 , further comprising one or more drag disks arranged between the first and second drag washers.
13. The spinning reel as recited in claim 10 , further comprising
a retaining mechanism for retaining the drag washers that is detachably disposed between an end face of the tubular section that faces the first and second drag washers and the first and second drag washers.
14. The spinning reel as recited in claim 9 , further comprising
a seal member arranged between the drag knob and the flange fastening member to prevent liquids from penetrating to the first and second drag washers.
15. The spinning reel as recited in claim 9 , further comprising
one or more drag disks arranged between the first and second drag washers.
16. The spinning reel as recited in claim 9 , further comprising
a retaining mechanism for retaining the drag washers that is detachably disposed between an end face of the tubular section that faces the first and second drag washers and the first and second drag washers.
