Patent number: 6964389Abstract: A fishing reel includes an adjustable dynamic drag mechanism and a static drag mechanism connected to a brake mechanism. The static drag mechanism allows a user to select a predetermined amount of static drag whereas the manually adjustable dynamic drag mechanism allows the user to instantly add more drag. The fishing reel also allows a user to set a maximum total drag (i.e., the combination of the static and the maximum dynamic drag) such that the user cannot accidentally add too much dynamic drag that could result in the total drag exceeding the strength of the fishing line. The fishing reel preferably includes an adjustable leverage mechanism that allows the user to select the desired amount of mechanical advantage. In the preferred embodiment, the brake mechanism includes a ratchet plate, a yoke, and a friction ring disposed between the plate and the yoke.Type: GrantFiled: December 5, 2003Date of Patent: November 15, 2005Inventors: Doug Hill, Mark J. McMenemy

Patent number: 6964388Abstract: A fishing reel includes a spool disk, a handle disk mounted coaxially and in juxtaposition with the spool disk, a winding handle or crank affixed to the handle disk, and a brake mechanism, including an actuator incorporated in the handle, for applying a drag braking torque between the spool disk and the handle disk. The braking torque is controllable by a user by squeezing the handle while holding the handle for cranking. Accordingly, the user does not have to let go of the winding handle in order to apply or vary the drag.Type: GrantFiled: April 5, 2004Date of Patent: November 15, 2005Inventor: Roger Ritter

Patent number: 6283394Abstract: An automatic gravity controlled fishing line brake which is automatically activated when the fishing line goes slack. The fishing line is fed through an opening in an arm of the brake assembly. When the line is taught, such as when it is being cast or when a fish strikes, the tension on the line is used to elevate the arm and disengage the brake. When the fishing line tension is relieved, such as when the line hits the water or when a fish changes direction, gravity automatically lowers the arm and engages the brake on the fishing reel line spool. The brake pads prevent the fishing line spool from rotating and thus prevent the unraveling of fishing line.Type: GrantFiled: November 16, 1999Date of Patent: September 4, 2001Inventor: Hirsh E. Ryen

Patent number: 5411218Abstract: A drag mechanism for a fishing reel having a spool shaft supported at both the ends thereof. The drag mechanism employs rolling members as drag members so that the durability of the mechanism is enhanced, and the dragging function thereof is kept stable and good for a long time even under severe conditions under which sea water, sand or the like is likely to cling to the mechanism. One of drag member holders is secured to the spool of the reel so as to be rotated together with the spool. The other of the holders is secured to the spool shaft so as to be rotated together therewith. The tapered outside circumferential surface of one of the holders faces the tapered inside circumferential surface of the other of them. The rolling members are fitted in between the tapered surfaces. The drag mechanism can be used to drag the reverse rotation of the spool by frictional resistances to the rolling and sliding of the rolling members.Type: GrantFiled: June 29, 1993Date of Patent: May 2, 1995Assignee: Daiwa Seiko, Inc.Inventors: Masayuki Uehara, Hiroshi Hashimoto, Tadashi Furubayashi
