Patent number: 6123280Abstract: A switchable anti-reverse mechanism for a fishing reel having an inner assembly which is fixedly mounted to the pinion of the fishing reel. The front end portion of the inner assembly is mounted to the rotor of the fishing reel. An outer assembly includes a housing having a plurality of slots and a cylindrical member having an opening extending coaxially with the pinion axis. The inner assembly is positioned within the opening of the outer assembly. The anti-reverse mechanism also includes means for allowing relative rotation around the pinion axis between the inner and outer assemblies in the line-winding direction and preventing relative rotation between the inner and outer assemblies in a reverse direction which is opposite to the line-winding direction. A plunger is movable along the plunger axis from a lock position to an unlock position, the plunger axis being parallel to the pinion axis.Type: GrantFiled: June 28, 1999Date of Patent: September 26, 2000Assignee: Heligear Engineering (HK) Co., Ltd.Inventors: Shu-Cheong Yuen, Chung Cheung

Patent number: 6116531Abstract: A fishing reel drag mechanism includes a spool for a fishing line, a brake drum attached coaxially to the spool, and a resilient circular brake shoe positioned inside the brake drum. The outer diameter of the brake shoe is slightly smaller than the inner diameter of the brake drum. A gap is provided on the brake shoe, and a movable spreader is positioned in the gap. When the spreader is moved to a first position, the brake shoe is in a relaxed position spaced from the brake drum, so that the spool may rotate with zero drag. When the spreader is gradually moved to a second position, the gap is gradually expanded by the spreader, and the brake shoe is gradually expanded against the brake drum. The drag on the brake drum is thus adjusted by changing the width of the gap with the spreader. Grooves arranged concentrically around the brake shoe provide additional compliance which improves smoothness in drag application and the range of drag force provided.Type: GrantFiled: November 19, 1998Date of Patent: September 12, 2000Assignee: Pacific ProductsInventor: John N. Young

Patent number: 6113018Abstract: A rolling member fitted into a guide recess and capable of performing a wedge action on a collar of a rotary quill is held by an annular holder in such a manner that the longitudinal movement of the rolling member can be restricted and the outside of the annular holder is rotatably fitted with an annular outer frame for restricting the outward movement of the rolling member, thereby forming a clutch main body. By rotating the annular holder by use of a rotation operation member provided in the annular holder, the rolling member is controlled such that it can be restricted and held at an operative position allowing the wedge action or at a non-operative position prohibiting the wedge action, thereby switching the rotary quill to a reversal preventive position or to a reversal allowable position. Also, the clutch main body is constructed as detachable one unit.Type: GrantFiled: June 7, 1999Date of Patent: September 5, 2000Assignee: Daiwa Seiko, Inc.Inventors: Kazuo Hirano, Eiji Shinohara, Takashi Higashimoto
