Patent number: 9334016Abstract: A bicycle rear derailleur comprises a first member, a second member and a locking structure. The second member is pivotally attached to the first member about a pivot axis. The locking structure fixes a relative position of the first and second members with respect to a rotational direction about the pivot axis. The locking structure is configured to release the relative position of the first and second members from a fixed state upon a predetermined load being provided to one of the first and second members in the rotational direction with respect to the pivot axis.Type: GrantFiled: July 13, 2012Date of Patent: May 10, 2016Assignee: Shimano Inc.Inventors: Satoshi Shahana, Shingo Funai

Patent number: 8870693Abstract: A bicycle derailleur comprises a base member, a movable member movably coupled to the base member, and a chain guide coupled to the movable member for rotation around a rotational axis. A resistance-applying element applies resistance to rotational movement of the chain guide, and a resistance control element moves between at least different first and second positions. The resistance control element is operatively coupled to the resistance-applying element so that the resistance-applying element applies different first and second resistances to rotational movement of the chain guide when the resistance control element is disposed in the respective first and second positions. A jolt element is disposed within the movable member and is operatively associated with the resistance control element to provide a tactile jolt to a user as the user moves the resistance control element from the first position to the second position.Type: GrantFiled: May 21, 2012Date of Patent: October 28, 2014Assignee: Shimano, Inc.Inventors: Satoshi Shahana, Shingo Funai

Patent number: 8870692Abstract: A bicycle derailleur comprises a base member, a movable member movably coupled to the base member, and a chain guide coupled to the movable member for rotation around a rotational axis. A resistance applying element applies resistance to rotational movement of the chain guide. A resistance control element moves between at least different first and second positions, wherein the resistance control element is disposed so that the resistance control element can be directly manipulated by a user without using a tool. The resistance control element is operatively coupled to the resistance applying element so that the resistance applying element applies different first and second resistances to rotational movement of the chain guide when the resistance control element is disposed in the respective first and second positions.Type: GrantFiled: September 30, 2010Date of Patent: October 28, 2014Assignee: Shimano, Inc.Inventors: Sota Yamaguchi, Shingo Funai

Patent number: 8375823Abstract: A bicycle shift control device is provided with a stroke controlling structure that provides distinct shifting position for an operating member that is pivotally arranged to move between a rest position, a first shifting position and a second shifting position. The stroke controlling structure includes a guide member configured and arranged to stop movement of the operating member at the first shifting position when the operating member is progressive moved in the single operating direction from the rest position. The guide member is further configured and arranged to control further movement of the operating member from the first shifting position to the second shift position when the operating member is moved in a non-operating direction away from the first shifting position without returning to the rest position.Type: GrantFiled: July 26, 2006Date of Patent: February 19, 2013Assignee: Shimano Inc.Inventor: Shingo Funai

Patent number: 8042427Abstract: A bicycle shifter is configured to ensure that the position where a main shifter body is attached to a bicycle can be easily varied. The bicycle shifter basically has a mounting bracket, a main shifter body and a fixing mechanism. The mounting bracket is preferably configured be fixed to a handlebar of a bicycle. The main shifter body is mounted on the mounting bracket and has a shifter mechanism in the interior. The fixing mechanism is a mechanism whereby the main shifter body can be fixed in place on the mounting bracket at an arbitrary attachment position between a first position and a second position.Type: GrantFiled: August 28, 2006Date of Patent: October 25, 2011Assignee: Shimano Inc.Inventors: Tatsuya Kawakami, Shingo Funai

Patent number: 7628095Abstract: A bicycle shifting mechanism is provided with a wire takeup member and a positioning mechanism. The wire takeup member rotates about a rotational axis to wind and release an inner wire of a shift cable. The positioning mechanism selectively maintains the takeup member in one of a plurality of predetermined shift positions. The positioning mechanism has a first movable positioning member, a second movable positioning member separately movable relative to the first positioning member, a first toothed segment that moves with the takeup member, a second toothed segment that moves with the takeup member. The first and second movable positioning members alternately engage and disengage one of the first and second toothed segments, respectively, as the first and second movable positioning members are moved to perform a shifting operation between sequential shift positions.Type: GrantFiled: May 10, 2006Date of Patent: December 8, 2009Assignee: Shimano Inc.Inventor: Shingo Funai
