摘要： A dual-sided chain catcher (170) adjustably connected to a structural member (204) of a bicycle frame of a bicycle having a front derailleur (100). The dual-sided chain catcher comprises an inner guard (178) and an outer guard (176) connected to one another over a top of a crankset of the bicycle comprising a small chainring (212) and a large chainring (210). The inner guard is positioned to prevent a bicycle chain (200) from falling inside the small chainring during down-shifts by the front derailleur. The outer guard is positioned to prevent the bicycle chain from falling outside the large chainring during up-shifts by the front derailleur.

摘要： Embodiments of a front derailleur gear shifting system including various unique chain guides attached to and operating from a single pivot point. This derailleur system provides a simple, yet, elegant and robust improvement in shifting technique over conventional, lateral motion front derailleurs. Embodiments of open and closed annulus chain guides having specially shaped lifting and pulling surfaces for acting upon a bicycle chain during shifting are also disclosed. Additionally, as an optional enhancement, a dual-sided chain catcher that prevents unintended over-shifts in either direction is disclosed.

摘要： A front derailleur for use on devices such as bicycles is movable about a yaw axis while it moves laterally. The front derailleur may include a linkage in between a mount and a cage, with the linkage pivoting about two non-parallel axes. The front derailleur may include a linkage in between the mount and the cage that has links of different effective lengths. The front derailleur may include a single link and a cam.

摘要： A manually operated bicycle front derailleur assembly (12) includes a linkage assembly (42), a lever member (160) and a connecting link (162). The linkage assembly (42) is supported to a fixing member (40) and includes an inner link (82) pivotally coupled to the fixing member (40) at a first pivot point (A1), an extension arm (106) extending from proximate the first pivot point (A1), an outer link (84) pivotally coupled to the fixing member (40) at a second pivot point (A2), and a chain guide (44) pivotally coupled to the inner and outer links (82, 84) to move between an inner shift position and an outer shift position. The lever member (160) is pivotally supported relative to the fixing member (40) and the bicycle frame (20) spaced apart from the first and second pivot points (A1, A2). The connecting link (162) operatively connects the lever member (160) to the extension arm (106) such that the linkage assembly (42) moves in response to movement of the lever member (160).

The linkage assembly (42) is supported to a fixing member (40) and includes an inner link (82) pivotally coupled to the fixing member (40) at a first pivot point (A1), an extension arm (106) extending from proximate the first pivot point (A1), an outer link (84) pivotally coupled to the fixing member (40) at a second pivot point (A2), and a chain guide (44) pivotally coupled to the inner and outer links (82, 84) to move between an inner shift position and an outer shift position. The lever member (160) is pivotally supported relative to the fixing member (40) and the bicycle frame (20) spaced apart from the first and second pivot points (A1, A2). The connecting link (162) operatively connects the lever member (160) to the extension arm (106) such that the linkage assembly (42) moves in response to movement of the lever member (160).

摘要： Ce dérailleur comporte, entre le mécanisme d'articulation habituel qui permet d'effectuer le déplacement latéral de l'organe (12) de guidage de la chaîne, un mécanisme d'articulation supplémentaire (10, 11) grâce auquel l'organe de guidage (12) peut effectuer un déplacement pratiquement libre et de grande amplitude dans un plan perpendiculaire à l'axe (X-X) du pédalier.
Ceci améliore très sensiblement les conditions de passage de la chaîne d'un plateau à un autre.
