Publication number: 20030218088Abstract: A handle assembly has a handle arm mounted to a fore-end of a handle shaft, a handle grip rotatively mounted to one end of the handle arm, and a rotation support portion made of a metal for rotatively mounting the handle grip to handle arm. The handle grip is a substantially egg-shaped member made of a synthetic resin, and is rotatively provided on the outward side of the rotation support portion. The handle grip is shaped such that the user can grip the whole of the handle grip with his palm. The handle grip also has first through fourth recesses such that the user can grasp the handle grip by attaching the thumb to the third recess, or pinch the handle grip between the thumb and fingertips by placing the thumb and index finger in the first and second recesses. Accordingly, it is possible to conduct high-speed winding easily.Type: ApplicationFiled: May 1, 2003Publication date: November 27, 2003Applicant: SHIMANO, Inc.Inventors: Hirokazu Hirayama, Kenichi Kawasaki, Tomoharu Sakurai

Publication number: 20030205637Abstract: A master gear shaft of a spinning reel has a through-hole having a rectangular cross-section formed on the inner periphery of the master gear shaft. A handle shaft has a head that interlocks with the right end of the master gear shaft, a trunk which extends from the head and is non-rotatively inserted into the through-hole, and a first threaded portion having a male screw projecting from the tip of the trunk. A handle arm has a boss for interlocking with the left end of the master gear shaft, a second threaded portion, which is a female screw threaded portion that engages with the first threaded portion and is provided on the boss, and an arm that extends from the boss in a direction interlocking with the master gear shaft. The handle assembly prevents a handle shaft from loosening from a master gear shaft in a spinning reel.Type: ApplicationFiled: April 15, 2003Publication date: November 6, 2003Applicant: SHIMANO.

Publication number: 20020185562Abstract: One preferred embodiment of the present invention provides a handle and shaft assembly including a rotatable shaft with a shaped end portion, where the shaped end portion has a non-circular cross-section. A handle cross-member is mounted to the shaft. A first distal portion of the cross-member is offset from the shaft. A pedestal is mounted to the distal portion of the cross-member. A ball portion is associated with the pedestal. In one embodiment, a knob defines a socket, which is coupled to the cross-member with a ball and socket joint. In a preferred shaft connection assembly, a locking member is fittingly engaged to the shaped end portion of the rotatable shaft such that the locking member and the rotatable shaft are substantially rigid in rotation. The locking member is also fittingly engaged with the cross-member such that the locking member and the cross-member are also substantially rigid in rotation.Type: ApplicationFiled: June 7, 2002Publication date: December 12, 2002Inventor: Joseph Landwerlen

Patent number: 6464158Abstract: For a round dual-bearing reel manufactured of metal, a handle attachment structure to impart a classic feel to the outward appearance of the reel unit, to prevent fishing line from getting tangled on, and debris from adhering to the outer surface of the handle. The handle attachment structure, for non-rotatively attaching a handle (2) to an end of a handle shaft (30) in which a male-threaded portion (30a) is formed, includes a handle arm (2a), a nut (28) and a retainer (29). The handle arm (2a) has an oblong hole (2c) with which the handle is mounted non-rotatively to the end of the handle shaft (30), and a non-circular accommodating recess (2d) of a predetermined depth formed around the oblong hole (2c) on an outer surface of the handle arm. The nut (28) has a polygonal nut portion (28), which is screwed to the end of the handle shaft (30).Type: GrantFiled: November 13, 2000Date of Patent: October 15, 2002Assignee: Shimano Inc.Inventor: Tomoharu Sakurai

Publication number: 20020096586Abstract: In known reels it has been attempted to attain the desired high speed, which is intended to maintain the tension of the line when a fish is swimming quickly towards the angler, by enlarging the outer diameter. This has the shortcoming that the handle is mounted on a large radius. This makes a fast cranking from the wrist impossible. When the handle is mounted on a smaller radius the force required in the struggle with a pulling fish becomes too great, which is equally disadvantageous.Type: ApplicationFiled: October 31, 2001Publication date: July 25, 2002Inventor: Karl-Heinz Henschel

Patent number: 6364229Abstract: A fishing reel having a frame and an operating mechanism on the frame. The operating mechanism includes a line carrying spool, an element that is rotatable relative to the frame around a first axis to cause line to be directed onto the spool, and a crank handle that is rotatable relative to the frame around a second axis to thereby cause the first element to be rotated around the first axis. The crank handle has a body with a first portion projecting radially in one direction from the second axis, a graspable element on the first body portion, and a counterbalance assembly. The counterbalance assembly includes a second portion of the body which projects radially from the second axis oppositely to the one direction and a first weight element attached to the second portion of the body.Type: GrantFiled: February 23, 2000Date of Patent: April 2, 2002Assignee: Brunswick CorporationInventor: Young Jue Kang

Patent number: 6315228Abstract: A baitcasting reel includes right and left cases constituting a reel body, and a level wind mechanism and a rotatable member disposed between walls of the right and left cases. The walls of the right and left cases and components interconnecting these walls are formed of a single material into an integral, one-piece unit. A lid is attached the integral, one-piece unit so that one of the cases has a space for accommodating a braking mechanism to act on a line takeup spool. The reel body has such an outer surface that outer wall surfaces of the integral, one-piece unit and lid are formed on the same plane.Type: GrantFiled: December 11, 1996Date of Patent: November 13, 2001Assignee: Shimano Inc.Inventor: Jun Sato

Patent number: 6105891Abstract: A handle assembly for a fishing reel includes a crank arm and a handle grip. The handle grip includes a linking member and a knob member having a smooth outer surface. The knob member defines first, second and third axes that are mutually perpendicular and meet at a point of intersection, and has a cross section in each plane perpendicular to the second axis that is bounded by at least a portion of a curve selected from the group consisting of a conic section and an oval. The portions define at least a portion of the smooth outer surface of the knob member. The cross sections decrease in area outward from the point of intersection along the second axis in either direction. The inventive handle assembly substantially conforms to the shape of a human palm, and enables a user to rapidly wind the knob member over an extended period of time without causing the user's hand to tire easily.Type: GrantFiled: December 2, 1998Date of Patent: August 22, 2000Assignee: Shimano, Inc.Inventors: Takeshi Ikuta, Jun Sato
