20120295745 | BICYCLE FRONT DERAILLEUR - A bicycle front derailleur is basically provided with a base member and a movable member. The base member includes a bicycle mounting portion. The movable member is movably supported to the base member between a retracted position and an extended position relative to the base member. The movable member includes a first guide plate having a first inner surface and a second guide plate having a second inner surface. The first and second inner surfaces face each other to form a chain receiving slot therebetween. The second guide plate includes an adjustable guide member that is arranged at the chain receiving slot to move between at least two different positions relative to the second guide plate. | 11-22-2012 |
20130072333 | BICYCLE FRONT DERAILLEUR - A bicycle front derailleur is basically provided with a base member, a movable member and a biasing arrangement. The biasing arrangement is operatively disposed between the base member and the movable member such that a biasing force of the biasing arrangement is smaller during an early range of a movement range of the movable member as the movable member moves from a first position to a second position. The biasing arrangement includes a first biasing member, a second biasing member and a pre-load body. The first and second biasing members selectively bias the movable member. The pre-load body maintains the second biasing member in a loaded state such that the second biasing member applies the second biasing force only after the movable member has partially moved from the first position towards the second position. | 03-21-2013 |
20130085026 | BICYCLE FRONT DERAILLEUR WITH A VARIABLE ACTUATION RATIO - A front derailleur comprises a base member structured to be attached to a bicycle frame member, a chain guide operatively connected to the base member, and an actuation mechanism coupled to the base member and to the chain guide for moving the chain guide relative to the base member between a first position corresponding to a location for positioning a chain on a first sprocket and a second position corresponding to a location for positioning the chain on a second sprocket. The actuation mechanism is configured so that an actuation ratio of the derailleur when the chain guide is located in the first position is greater than or equal to 1.5 times the actuation ratio when the chain guide is located in the second position. | 04-04-2013 |
20140038759 | CHAIN CONNECTING PIN - A chain connecting pin basically includes a pin body, a connecting portion and an inserting portion. The pin body has a first axial end face and a second axial end face, the second axial end face having a recessed surface with respect to an outermost edge of the second axial end face. The connecting portion is attached to the recessed surface of the second axial end face of the pin body. The inserting portion is attached to the connecting portion. | 02-06-2014 |
20140128189 | BICYCLE DERAILLEUR - A bicycle derailleur is basically provided with a base member, a movable member and a connecting structure. The base member includes a bicycle mounting portion. The movable member is movable with respect to the base member between a first position and a second position that is farther than the first position from the base member. The connecting structure movably connects the movable member to the base member. The connecting structure moves the movable member with an actuation ratio that descends and then ascends as the movable member moves from the first position towards the second position. | 05-08-2014 |
20140148287 | FRONT DERAILLEUR - A front derailleur basically includes a fixed member, a movable member, a driven link and a first link. The fixing member is configured to be fixed to a bicycle frame. The movable member is movably supported with respect to the fixed member. The driven link is operatively coupled to the movable member. The first link movably connects the movable member to the fixed member, and is adjustably coupled to the driven link in a fixed position by a fixing structure to establish a fixed rest position of the movable member with respect to the fixed member. | 05-29-2014 |
20140155204 | FRONT DERAILLEUR - A front derailleur unit basically includes a fixed member and a movable member. The fixed member is configured to be releasably attached to a plurality of different type mounting units. The different type mounting units is detachably attached to a bicycle frame. The movable member is movably supported to the fixed member to move with respect to the fixed member. | 06-05-2014 |
20140155205 | FRONT DERAILLEUR - A front derailleur basically includes a fixed member, a main body, a movable member and a support member. The fixing member is configured to be fixed to a bicycle frame. The main body is attached to the fixing member. The movable member is movably supported to the main body with respect to the fixing member. The support member is movably attached to one of the fixing member and the main body. The support member including an operated portion selectively operated by an operating element and positioned between the fixing member and the main body. | 06-05-2014 |
20140349793 | FRONT DERAILLEUR - A front derailleur is basically provided with abuse member, a chain guide, a link mechanism and a cable guiding structure. The base member is fixedly coupled to a bicycle. The chain guide is configured to guide a chain. The link mechanism movably couples the chain guide to the base member between a retracted position and an extended position in response to movement of an operation cable. The link mechanism includes a cable attachment portion that is configured to be attached to the operation cable. The cable guiding structure guides the operation cable from the cable attachment portion. The cable guiding structure is disposed on at least one of the base member and the link mechanism. The cable guiding structure has a cable exit that is arranged such that the operation cable exits forwardly from the cable guiding structure towards the front of the bicycle. | 11-27-2014 |
20150018145 | FRONT DERAILLEUR - A front derailleur is provided for mounting to a bicycle having a crank axis. The front derailleur is provided with a base member, a chain guide and a link mechanism. The base member is mounted on the bicycle for positioning in a predetermined adjustment direction. The chain guide guides the chain. The link mechanism movably couples the chain guide to the base member. The link mechanism includes a first link member pivotally arranged in relation to the base member about a first link axis and pivotally arranged in relation to the chain guide about a second link axis. The first link axis and the second link axis are arranged non-parallel and non-orthogonal to the predetermined adjustment direction when viewed from the axial direction of the crank axis in a state where the base member is mounted to the bicycle. | 01-15-2015 |
