  • Patent number: 7618003
    Abstract: A baitcast reel includes a spool having a spool shaft rotatably connected to the reel, a centrifugal brake including a shoe housing connected to the spool shaft, rotated together with the spool, and having a plurality of brake shoes slidably inserted in grooves radially formed, a brake drum accommodating the shoe housing and the guide plate, and having a plurality of brake stages frictionally contacting the brake shoes for selectively restricting rotation of the brake housing, and a knob rotatably coupled to the brake housing for moving the brake drum moving portion back and forth, and a magnetic brake including a dial positioned coaxially with the knob and being flush with a side of a main cover, and a magnet holder having magnets moved back and forth along a rotating shaft by a cam surface of the dial.

  • Patent number: 6959886
    Abstract: A brake device of a bait casting reel includes a shoe housing coupled to the spool shaft and having a plurality of pairs of sliding grooves and a plurality of pairs of insertion pins; a plurality of brake shoes slidably received in the sliding grooves and defined with elongate holes in which the insertion pins are inserted; a brake drum defining a plurality of braking surfaces which have different inner diameters; a brake drum moving member into which the brake drum is fitted; a sub cover fixed to a main cover with the brake drum moving member accommodated in the sub cover; springs placed between the brake drum moving member and the sub cover; and a cam member rotatably coupled to the sub cover and defined with a plurality of sets of cam grooves which have different engagement heights.

  • Patent number: 6957787
    Abstract: A centrifugal braking device for a bait casting reel. A spool has a spool shaft which is rotatably coupled to a reel body. A brake housing is coupled to one end of the spool shaft to be rotated integrally with the spool and has sliding grooves. Brake elements are slidably received in the sliding grooves to be rotated integrally with the spool. A brake drum can be brought into frictional contact with the brake shoes to selectively limit rotation of the brake housing to some extent. The brake elements are positioned differently from one another by a predetermined angle along a circumferential direction and slidably received in the sliding grooves, respectively. A frictional force between outer end surfaces of the brake elements and an inner surface of the brake drum is selectively increased or decreased depending upon a rotation direction of the brake elements.
