The first sound producing portion is mounted to the spool shaft so as to be unrotatable when the spool rotates in a line releasing direction and rotatable when the spool rotates in a line winding direction. The pawl member is urged toward the saw tooth portions by a spring member. The spinning reel sound producing mechanism produces sound only when the spool rotates in the line releasing direction.Type: GrantFiled: February 25, 2004Date of Patent: December 6, 2005Assignee: Shimano Inc.Inventor: Ken'ichi Sugawara

Patent number: 6880777Abstract: A first bearing and a second bearing are mounted on an inner peripheral side of an inner peripheral portion of a bobbin portion. The first bearing and the second bearing are rotatably mounted on a spool shaft a tubular retaining member. An annular member is mounted to an outer periphery of the spool shaft so as to be prevented from moving rearward relative to the spool shaft. A through hole passes through the retaining member. The retaining member is non-rotatably coupled to the spool shaft by a pin member. A nut member is mounted on the outer periphery of the spool shaft, such that the retaining member is interposed and fixedly held between the annular member and the nut member.Type: GrantFiled: December 4, 2003Date of Patent: April 19, 2005Assignee: Shimano Inc.Inventor: Ken'ichi Sugawara

Patent number: 6874718Abstract: A fishing spinning reel includes a spool member surrounding rotatably a spindle for reeling a fishing line, and having front and rear friction walls. Front and rear friction members are mounted on the spindle and respectively have abutment areas to confront and to be brought into frictional engagement with the front and rear friction walls. A friction force adjusting member is retainingly movable relative to the spindle so as to be operated between depressing and releasing positions to hold the abutment area of the rear friction member in first and second frictional engagements of greater and smaller frictional forces with the rear friction wall, respectively.Type: GrantFiled: September 16, 2003Date of Patent: April 5, 2005Inventor: Liang-Jen Chang

Publication number: 20040227027Abstract: Drag adjustment knob adjusts the braking force applied to a spool mounted on a spool shaft that has a single-thread first male screw on its front end. The drag adjustment knob includes first and second adjustment units, a transmission unit, and a pressing unit. The first adjustment unit includes a first female screw that screws onto the first male screw. The transmission unit is non-rotatably but axially movably mounted onto the spool shaft to be in contact with the first adjustment unit, and includes a multi-thread second male screw. The second adjustment unit includes a second female screw, which screws onto the second male screw and has a greater screw lead than that of the first female screw. The pressing unit is disposed between the second adjustment unit and the drag mechanism so as to come into contact with both, and is non-rotatable but axially movable with the spool shaft.Type: ApplicationFiled: April 29, 2004Publication date: November 18, 2004Inventors: Koji Ochiai, Kei Saito, Tomokazu Kitazaki

Patent number: 6769639Abstract: A spinning reel has a drag assembly in its spool on one end of the reel body, and an adjustment knob for the drag assembly on another end of the reel body, where it is conveniently accessed during use of the reel. The reel has a handle arm with two slidably disposed handle arm portions, which are releasably secured together at selected positions to provide a variable length handle arm.Type: GrantFiled: July 18, 2001Date of Patent: August 3, 2004Assignee: W. C. Bradley/Zebco Holdings, Inc.Inventors: Robert W. Koelewyn, Donald C. Liu

Patent number: 6766975Abstract: An outer-side holding member (5) of a braking device (A) is fitted to the inner side of a large-diameter recessed portion (2g) in a rear portion of the inner side of a fishing-line winding barrel portion (2h) of a spool (2) in such a manner as to be prevented from rotating, and is prevented from coming off. An adjusting member 8 is provided at a distal end portion of the spool shaft for adjusting braking force of the braking device by relatively displacing an outer-side holding member (5) and the inner-side holding member (7) of the braking device in an axial direction.Type: GrantFiled: August 29, 2002Date of Patent: July 27, 2004Assignee: Daiwa Seiko, Inc.Inventor: Nobuyuki Yamaguchi

Patent number: 6726137Abstract: A spincast fishing reel has a reel frame to which front and rear covers are attached. The rear cover includes a pivotable thumb button which is depressed by a user when fishing line is to be cast. The front cover closes the face of the reel, but defines a forward opening through which the fishing line extends. A normally nonrotatable line spool is located inside of the front cover on a spool hub of the reel frame. Fishing line is wound onto the line spool by a rotatable pickup head located forward of the line spool. An improved drag arrangement includes a drag nut mounted on a threaded portion of the spool hub. A gear train arrangement is provided to operatively connect a suitable thumb wheel with the drag nut. Rotation of the thumb wheel by a user causes rotation 6f the drag nut, which varies the drag force imposed on the line spool.Type: GrantFiled: January 16, 2002Date of Patent: April 27, 2004Assignee: Shakespeare CompanyInventor: Chi Shing Li

Patent number: 6612511Abstract: A drag knob of a spinning reel includes a main knob unit, a presser unit and a retaining member. The knob unit is a die-cast member having a concave portion provided on the rear side, and interlocking grooves that are formed on the front side at a certain spacing in circumferential direction, and extend along an axis direction through an outer periphery of the concave portion up to a groove end. A portion of the presser unit is accommodated in the concave portion. The retaining member has corner portions that interlock with the interlocking grooves, and contact portions that are formed in one piece with the corner portions and contact the presser unit from the rear side. The retaining member has enough elasticity to be mounted in the concave portion to retain the presser unit. The present invention reduces the manufacturing costs of a fishing reel.Type: GrantFiled: December 6, 2002Date of Patent: September 2, 2003Assignee: Shimano Inc.Inventor: Keigo Kitajima
