US 6,412,720 B1 · Dual-bearing reel brake device and drag cover attachment structured therefor

Abstract

A double-drag type lever-drag mechanism for a double-bearing trolling reel. The drag mechanism is configured to improve overall reel braking and drag performance by securing the brake release state reliably and by a design that curbs increase in spool inertia and provides for ease of operation and precision in attaching the drag cover. The lever drag mechanism 7 brakes the spool 3 rotation in the line spool-out direction, and is equipped with a brake disk 25 non-rotatably fitted to one end of the spool such to be axially shiftable a predetermined distance. Sandwiching the brake disk 25 between friction disk 26, immobilized against axially outward movement, and axially shiftable friction disk 27 rotates the drag/brake disks 25-27 unitarily with the spool 3. Against the spool 3 a coil spring 28 urges the brake disk 25 away from the spool 3. A shifting mechanism 29 reciprocates the spool 3 and drag/brake disks 25-27 axially. The mounting configuration for the drag cover includes a circular groove 3c radially beyond which is a plurality of circumferentially spaced threaded holes 3d in the end face of the spool 3; a tubular centering portion 41c that snugly fits into the circular groove 3c, radially extending from which is a ring-shaped mounting portion 41b; an O-ring 42 in the circular groove 3c making sealing contact circumferentially with the tubular centering portion 41c; and a plurality of machine screws 44 passing through-holes in the mounting portion 41b and screwed into the threaded holes 3d.

Dependent claims

A dual-bearing fishing reel spool-braking device for use in a dual-bearing reel having a reel main body, a handle rotatably supported by the reel main body, and a spool fitted rotatably to the reel main unit, rotation generated by the handle being transmitted to the spool through a rotational transmission path, said dual-bearing reel braking device being provided in the rotational transmission path to brake the rotation of the spool in a line-out direction, said dual-bearing reel braking device comprising:

a brake disk non-rotatably mounted on one end of the spool with a gap therebetween, such that said brake disk is shiftable a predetermined distance axially along the spool;
a first disk member to which rotation from the handle is transmitted, said first disk member being disposed facing said brake disk on a side of said brake disk away from the spool, said first disk member being axially immobile at least in a direction away from said brake disk, said first disk member being unrotatable in a line-out direction relative to the reel main unit;
a second disk member disposed facing said brake disk on a side of said brake disk closer to the spool, said second disk member being axially shiftable so as to part away from said first disk member, said second disk member being rotatable when said first disk member and said second disk member sandwich said brake disk;
a first urging member for urging said brake disk axially away from said second disk member;
and
shifting means for reciprocatingly shifting the spool and said second disk member axially to enable said first and second disk members to sandwich said brake disk.
