摘要： A bicycle derailleur gear shifting system having a rotatable handgrip actuator cam (74) which is coupled with derailleur shifting mechanism (54) through a control cable system (60, 64) so as to control the derailleur mechanism (56, 58). Separate actuator cams are associated with the front and rear derailleurs. For the down-shifting direction, at least the rear derailleur cam is configured so as to substantially compensate for increasing force of the derailleur return spring (208) so as to substantially compensate for numerous cumulative lost motions in the derailleur shifting mechanism (54) and cable system (60, 64), and for chain gap variations; and so as to overshift the chain a sufficient amount beyond the destination freewheel sprocket (54a) so that the chain will approach the destination sprocket (#5) in the same direction as it would in the up-shift direction, but not sufficient to cause a double shift, or derailling from the #1 sprocket. A front derailleur cam is configured to provide fine-tuning for ''cross-over'' riding.

摘要： A linear derailleur (200) for positioning a drive chain (48) in response to displacement of a plurality of control cables (86, 88). The derailleur (200) includes a linear actuator having a substantially uniform actuation ratio over the range of motion of the actuator and, hence, derailleur (200). The linear actuator also has a mean actuation ratio over its range of motion equal to Cos theta:1, where theta equals the angle of inclination of the actuator.

摘要： A hand-operated shift actuator (16) displaces a derailleur control cable (22). The actuator (16) includes a stationary member (60) that is affixed relative to a bicycle handlebar (44). Rotation of the rotating member (62) causes the control cable (22) to be displaced, thus actuating the derailleur (24) to which the control cable (22) is attached. A plurality of detent positions (104-115) each correspond to a derailleur overshift position. The rotating member (62) is rotatable in a first direction to any of these detent positions (104-114). A spring-loaded overshift corrector (90, 142) urges the rotating member (62) from an overshift position in a second direction to a respective new desired sprocket center position when the rotating member (62) is released by the hand of the rider.

Separate actuator cams are associated with the front and rear derailleurs. For the down-shifting direction, at least the rear derailleur cam is configured so as to substantially compensate for increasing force of the derailleur return spring; so as to substantially compensate for numerous cumulative lost motions in the derailleur shifting mechanism and cable system, and for chain gap variation; and so as to overshift the chain a sufficient amount beyond the destination freewheel sprocket so that the chain will approach the destination sprocket in the same direction as it would in the up-shift direction, but not sufficient to cause a double shift, or derailling from the #1 sprocket. A front derailleur cam is configured to provide fine-tuning for ''cross-over'' riding. In one form of the invention a secondary overshift boost cam is added axially in tandem with the primary cam, and is adaptable to both the front and rear derailleur shift actuators.

摘要： An improved two-piece control cable adjustment device (20) for offsetting a change of relative length between the outer sheath (12) and control wire (18) operatively linking a control mechanism such as a bicycle shifter (20) or brake lever to an operating mechanism such as a derailleur (24) or brake. The adjustment device includes an adjuster nut (40) having a threaded bore (42) cooperating with a mounting member threaded shaft (30) and an indexing mechanism achieved by the relative elastic deformation of rotatably engaging protrusions (32) and/or detents circumferentially formed on the cooperating adjuster nut (40) and mounting member, thereby enables riders to sense each increment of stepped adjustment. The adjuster nut (40) is configured to protectively enclose both the cooperating threads (30) and engaging portion of the protrusions (44) and detents from environmental exposure thereby preventing the trapping of external particles in the threads, a primary concern for use in the harsh mud and dirt environment common to off-road biking, and in turn preventing the premature wear and replacement of parts.
摘要翻译：一种用于抵消外护套（12）和控制线（18）之间的相对长度变化的改进的两件式控制电缆调节装置（20），其将诸如自行车换档器（20）或制动杆的控制机构可操作地连接到操作机构，如拨链器（24）或制动器。调节装置包括具有与安装构件螺纹轴（30）配合的螺纹孔（42）的调节螺母（40）和通过可旋转地接合的突出部（32）和/或棘爪的周向形成的相对弹性变形实现的分度机构在协调的调节螺母（40）和安装构件上，从而能够使乘客感测到阶梯式调节的每个增量。调节螺母（40）构造成保护性地包围协作螺纹（30）和突出部（44）的接合部分和棘爪不受环境暴露，从而防止外部颗粒捕获在螺纹中，这是主要关注在恶劣的泥土和土壤环境常见于越野自行车，反过来又能防止零件过早磨损和更换。

摘要： A brake operating device (30) is configured such that actuation of the brake lever (34) around the lever pivot (36) displaces the cable (38) in a direction transverse to the cable length toward the lever pivot (36), as the user is actuating the brake lever (34). This provides at least a 33 % increase in mechanical advantage over the actuation range of the brake lever (34).

摘要： A bicycle derailleur gear shifting system having a rotatable handgrip actuator coupled with a derailleur shifting mechanism through a control cable system so as to control the derailleur. The derailleur (50) includes an arcuate cable entraining surface (78) which substantially reduces the variation and magnitude of the actuation ratio between control cable linear displacement and movement of the derailleur p-knuckle (88). A b-knuckle flange (160) militates against the derailment of the drive chain from the upper guide wheel while permitting maximum lateral flexing of the drive chain (48) during shifting between sprockets (46) on the freewheel. A rigid arcuate surface (174) may be provided as an extension of the b-knuckle (170) in replacement of a segment of a Bowden cable housing (38) to obviate the accumulation of water and foreign matter.

摘要： A bicycle gear shifting system (10) having rotatable front and rear handgrip shift actuators (60, 66) operatively associated with control cables for shifting respective front and rear derailleur mechanisms. In some forms of the invention the control cable (62) is directly actuated by the handgrip rotator (60, 66). A cam on either the handgrip rotator (60, 66) is configured so as to substantially compensate for increasing force of the derailleur return spring during down-shifting.
