  • Patent number: 6634586
    Abstract: An anti-reversional mechanism for a trolling reel is to provide a ratchet wheel on a pressing wheel of the trolling reel, and two pawl members detachably engaged with the ratchet wheel for preventing the pressing wheel from reversional rotation. Each of the pawl members has an elongated slot. A control ring is elastically clamped on the periphery of the pressing wheel and has two driving rods respectively received in the elongated slots of the pawl members. Since the orientation of the elongated slot and the displacement direction of the control ring form a predetermined included angle, the pawl members are driven by the control rods of the control ring to be disengaged with said ratchet wheel while the pressing wheel rotates in a right direction such that the pressing wheel can rotate freely.

  • Publication number: 20030146321
    Abstract: A one-way clutch for a fishing spool includes a hollow cylindrical mounting seat, an inner ring sleeved non-rotatably on a driving shaft, and a retainer sleeved on the inner ring. An outer ring is sleeved on the retainer, and is disposed within the seat. A cover is connected fixedly to the seat so as to confine the inner ring, the retainer, and the outer ring within the seat. A bearing is disposed between the cover and the shaft. Several rollers are retained on an annular wall of the retainer between the inner and outer rings. A push lever of the retainer is operable so as to rotate the annular wall between a braking position, where the shaft is permitted to rotate in a single direction, and a release position, where the shaft is permitted to rotate in two directions.
