Patent number: 10605299Abstract: A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.Type: GrantFiled: May 22, 2015Date of Patent: March 31, 2020Assignee: Shimano Inc.Inventors: Atsuhiro Nishimura, Kenji Ose, Takamoto Asakawa

Patent number: 9829035Abstract: A bicycle control cable is provided with a central wire, an outer case and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The outer case surrounds at least a portion of an axial length of the central wire. The outer case has a radially innermost surface. The radial protrusion spirally extends along one of either the radially outermost surface of the central wire or the radially innermost surface of the outer case in a direction intersecting with a center longitudinal axis of the bicycle control cable. The radial protrusion reduces a sliding resistance of the central wire relative to the outer case. The central wire is configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the bicycle control cable within the outer case to operate a bicycle component.Type: GrantFiled: May 17, 2012Date of Patent: November 28, 2017Assignee: Shimano Inc.Inventors: Atsuhiro Nishimura, Kenji Ose, Takamoto Asakawa, Osamu Kariyama, Yoshimitsu Miki, Tooru Iwai

Publication number: 20130081508Abstract: A bicycle control cable is provided with a central wire and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The radial protrusion extends along the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire. The radial protrusion reduces a sliding resistance of the central wire. The central wire and the radial protrusion are configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.Type: ApplicationFiled: September 29, 2011Publication date: April 4, 2013Applicant: SHIMANO INC.Inventors: Atsuhiro NISHIMURA, Kenji OSE, Takamoto ASAKAWA

Patent number: 7758250Abstract: A bicycle hub is provided that comprises a hub axle, a hub body rotatably mounted on the hub axle by a pair of bearings. The bicycle hub also has an inner tubular structure including a pair of inner tubes. One of the inner tubes is fixedly secured relative to a first body end adjacent to a first bearing, while the other inner tube is fixedly secured relative to the second body end adjacent to the second bearing. The inner tubes have inner free end portions that are telescopically arranged so that the inner tubes can be used with several different has that have different axial widths.Type: GrantFiled: October 27, 2005Date of Patent: July 20, 2010Assignee: Shimano Inc.Inventors: Takanori Kanehisa, Atsuhiro Nishimura

Patent number: 7461904Abstract: A bicycle hub assembly includes a hub shell, a freewheel body and a sealing structure there between. The sealing structure includes a seal that has a lip that extends in an axial direction to engage a radially extending surface on the sealing plate. In one embodiment, the seal is installed in a seal retaining portion formed on the hub shell. In another embodiment, the seal is installed on the freewheel and contacts a radially extending surface on the hub shell.Type: GrantFiled: June 17, 2005Date of Patent: December 9, 2008Assignee: Shimano Inc.Inventors: Takanori Kanehisa, Atsuhiro Nishimura

Patent number: 7413350Abstract: A bicycle hub is provided that comprises a hub axle, a hub body, a bearing and a clearance adjusting member. The bearing includes an outer ring coupled to the hub body, an inner ring coupled to the hub axle, and a plurality of rolling components disposed between the outer ring and the inner ring. The clearance adjusting member is disposed with respect to the outer ring of the bearing such that at least a portion of the clearance adjusting member is disposed axially inwardly of the outer ring. The clearance adjusting member is configured and arranged to prevent a grease inside the bearing to leak toward an axially inward direction of the hub axle with a prescribed radial clearance being maintained between the clearance adjusting member and one of the hub axle and the outer ring of the bearing.Type: GrantFiled: April 27, 2007Date of Patent: August 19, 2008Assignee: Shimano Inc.Inventors: Takanori Kanehisa, Atsuhiro Nishimura
