A pair of elastic sealing rings are respectively interposed between the free ends of the flange portions and the peripheral wall so as to seal the first and second gaps for preventing dust and liquid from entering into the end chambers via the opening and the intermediate chamber from the exterior of the casing.Type: GrantFiled: January 23, 2002Date of Patent: June 10, 2003Inventor: Eugene Hong

Patent number: 6550709Abstract: The fly fishing reel of this invention comprises a housing that includes a mounting shoe for attaching the reel to a fishing rod, a hub attached axially to the center of the housing, a spool containing a centrally mounted spindle supported within the hub, and an adjustable, highly effective and efficient drag system coupled between the spool and housing. The drag system is a unidirectional variable friction brake that includes a first and second inner bearing races and first and second outer bearing races. The inner bearing races each have convex hemispherical friction surfaces. The outer bearing races each have concave hemispherical friction surfaces. The outer races are rotationally fixed by interlocking geometry with the hub. The inner races encase a unidirectional roller clutch which receives the spindle attached to the spool. The hemispherical friction surfaces are longitudinally concentric with the rotational axis of the spindle.Type: GrantFiled: April 10, 2001Date of Patent: April 22, 2003Assignee: Native ReelsInventor: Michael Vashro

Patent number: 6511007Abstract: The double-bearing type reel has a spool for winding up a fishing line and a drag mechanism 5 slipping to rotate the spool when a predetermined tension acts on the line wound round the spool. The drag mechanism comprises an outer ring, an inner shaft, a plurality of rollers arranged between the outer ring and the inner shaft so as to roll, and a torque adjusting section for moving the outer ring and the inner shaft relatively in an axial direction. The rollers are arranged between tapered roll surfaces which are an inner circumferential surface of the outer ring and an outer circumferential surface of the inner shaft and have center axes inclined against center axes of the outer ring and the inner shaft.Type: GrantFiled: October 20, 2000Date of Patent: January 28, 2003Assignee: Ken Matsuura Racing Service Co., Ltd.Inventor: Ken Matsuura

Patent number: 6508426Abstract: This invention relates to a fishing reel (10) which comprises a reel body (12), a spool (14) rotatable relative to the reel body, a handle (16) for rotating the spool, and a drive bearing (32) connecting the handle to the spool. The drive bearing (32) is in the form of a ball-bearing including a plurality of balls (34) which are mounted to the handle (16) and which are arranged to rotate so that rotation of the handle (16) at a first velocity is transferred to the spool (14) at a second velocity greater than the first velocity.Type: GrantFiled: November 30, 2001Date of Patent: January 21, 2003Inventor: Giles Whittle-Herbert

Publication number: 20030001035Abstract: Spool is mounted rotatably via bearings on spool shaft of a spinning-reel, and is furnished with first and second bearing housings, bobbin trunk, and front and rear flanges. At least a part of second bearing housing is made of metal. The bobbin trunk, which is furnished with the first and second bearing housings, is a synthetic-resin manufacture outer circumferentially onto which fishing line is wrapped. The front and rear flanges are arranged on the front and rear of the bobbin trunk, and are larger in diameter than the bobbin trunk. With the present invention, it is easier to take out and replace the spool bearing although the bobbin trunk is subjected to compressive force.Type: ApplicationFiled: May 31, 2002Publication date: January 2, 2003Applicant: SHIMANO, INC.Inventor: Yasuhiro Hitomi

Patent number: 6460793Abstract: To avoid an odd sensation when gripping a dual-bearing fishing reel unit and to prevent attaching/detaching by mistake, a dual-bearing reel body having: a spool-cranking handle disposed on one side surface and a spool disposed inside, and including a frame; a spool support member; a nub; a first side-cover; and a second side-cover. The reel frame includes a pair of proximal and distal side-plates and arranged at a predetermined spacing, and a circular opening a through which the spool can be passed is provided on the distal side-plate. The spool support member rotatively supports one end of a spool shaft and is detachably mounted to distal side-plate, such that detaching the spool support member reveals the first opening. The nub is for attaching/detaching the spool support member and is provided on the spool support member. The first side-cover can be opened and closed and covers the outer side of the side-plate, together with the spool support member and the nub.Type: GrantFiled: October 2, 2000Date of Patent: October 8, 2002Assignee: Shimano, Inc.Inventors: Hirokazu Hirayama, Jun Sato

Patent number: 6457662Abstract: A spinning reel rotor drive device that keeps thrust force from acting upon the one-way clutch. The rotor drive device 5 for a spinning reel drives a rotor in the reeling direction according to the rotation of a handle rotatably supported on a reel unit, and prevents the rotor from reversing in the line winding-out direction, said apparatus comprising a face gear 11, a pinion gear 12, a bearing 16, a restriction member 17, and a rotation check mechanism 13. The bearing is fitted in a state of restricted movement to the rear thereof on the barrel 14 of the reel unit in order to rotatably support the pinion gear on the reel unit. The restriction member is fixed to the reel unit in order to restrict the forward movement of the bearing. The rotation check mechanism has a roller-type one-way clutch provided ahead of the restriction member, and prevents the rotor from reversing in the line winding-out direction.Type: GrantFiled: July 13, 2000Date of Patent: October 1, 2002Assignee: Shimano Inc.Inventor: Jun Sato

Publication number: 20020125358Abstract: Nut that screws together with pinion gear, and bearing that is arranged on the inner circumferential side of the nut, are provided on the front of a spinning-reel rotor. Pressing member is mounted on the front faces of the nut and bearing, such that it abuts on outer race of bearing. Pressing member is installed so as to be rotatable with respect to spool shaft, which is a rod element. Pressing member is water-repellency treated over all its surfaces, including the face that forms a clearance with spool shaft. The present invention prevents invasion of water droplets into rotatory-component clearances in a water-sealing component assembly composed of a relatively rotatable plurality of components, while sustaining rotational efficiency of the rotatory components.Type: ApplicationFiled: February 25, 2002Publication date: September 12, 2002Applicant: SHIMANO INC.Inventor: Koji Takikura

Publication number: 20020113156Abstract: A fishing reel includes a spool rotatably supported in a bearing arrangement on a spindle unit. The spindle unit is a held-together unit incorporating an elongated spindle and a bearing housing supported on the spindle by at least two spaced apart rolling bearings. Annular end washers on the spindle shield off the interior of the housing from the surrounding environment via a small slot acting as a seal. The housing has at least one exterior radially extending shoulder and the spool has at least one internal projection intended to engage the shoulder of the housing to define the axial position of the spool relative to the bearings while also taking up axial load in one direction. A resilient member between the bearing housing and the spool gives play-free contact between the housing and the spool and gives a pretension of the spindle unit against the shoulder of the housing.Type: ApplicationFiled: February 1, 2002Publication date: August 22, 2002Inventors: Lars Andren, Folke Ostling, Maurice Richard, Patrik Svensson
