摘要： A bicycle gear shifting system having rotatable front and rear handgrip shift actuators operatively associated with control cables for shifting respective front and rear derailleur mechanisms. In some forms of the invention the control cable is directly actuated by the handgrip rotator, while in other forms the shifter rotator drives a separate "jack spool" which in turn actuates the control cable. A cam on either the handgrip rotator or the jack spool is configured so as to substantially compensate for increasing force of the derailleur return spring during down-shifting. Compensation is provided in the shift actuators of the invention for various lost motions in the derailleur shifting mechanisms and control cable systems. The shift actuators of the invention also provide overshift movement of the derailleur mechanisms in the down-shifting direction so as to overshift the bicycle chain a sufficient amount beyond the destination derailleur sprocket so that the chain will approach the destination sprocket in the same direction as it would in the up-shifting direction. The shift actuators of the invention also provide equalization for the higher derailleur return spring force during down-shifting than during up-shifting, and allow fine-tuning to avoid chain rasp, which is particularly important for "cross-over" riding.
摘要翻译：一种自行车换档系统，其具有可操作地与用于移动相应的前拨链器和后拨链器机构的控制电缆相关联的前后手柄换档致动器。在本发明的一些形式中，控制电缆由手柄旋转器直接致动，而在其它形式中，换向器旋转器驱动单独的“千斤顶滑阀”，从而驱动控制电缆。手柄旋转器或千斤顶卷轴上的凸轮被构造成基本上补偿了向下换档期间拨链器复位弹簧的增加的力。在本发明的换档致动器中提供了用于拨链器换档机构和控制缆索系统中的各种不动的补偿。本发明的换档致动器还提供拨链器机构沿向下移动方向的过渡运动，以便使自行车链条超出目的地拨链器链轮的足够数量，使得链条将以与其相同的方向接近目的地链轮会在向上移动的方向。本发明的换档致动器还提供了在下移期间比在上移期间更高的拨链器复位弹簧力的均衡，并且允许微调以避免链锉，这对于“交叉”骑乘特别重要。

摘要： The disclosed speed-change gear includes a fitting secured to the frame of a bicycle, a parallel link means having an outside link and an inside link whose one ends are pivotally connected to the fitting, a movable member pivotally connected to the opposite ends of the inside and outside links, a changeover frame rotatably secured to the movable member, which changeover frame carries a guide wheel and a tension wheel of a chain, and a cam means adapted to selectively move said movable member so as to shift the speed-change ratio by changing the position of said changeover frame to shift the chain to the desired step of a multi-step sprocket assembly of the bicycle. The cam means has a spring-biased cam rotatably mounted on a shaft connecting the outside link to the fitting, which cam rotates together with a wire-operated reel coaxially mounted on said shaft. The rotation of the cam actuates said parallel link means through a lever pivotally carried by a shaft connecting the inside link to the fitting.

摘要： A connecting mechanism for two members of a bicycle derailleur is provided with first and second bearings interposed between a supporting tubular member provided at a first member, such as a base member or movable member of the derailleur, and a shaft provided at a second member, such as a bracket member or chain change-over cage, each of the first and second bearings comprising a tubular portion inserted between the inner periphery of the supporting tubular member and the outer periphery of the shaft and a flange portion opposite to an end face of the supporting tubular member. At least one of the first and second bearings is provided at the flange portion thereof with an annular groove opening at one axial side of the flange portion. An annular elastically deformable sealing member is loosely fit into the groove and is elastically deformed to compensate for errors in the axial dimensions of the supporting tubular member, shaft, or bearings, thereby eliminating gaps produced at the surfaces of members slidably contacting with the bearings.

摘要： A four link member derailleur for a bicycle, which comprises a fixing member, two linkage members, and a movable member having a chain guide, and a return spring is provided with a control element having a plurality of engageable portions corresponding to the number of speed change stages and with a retainer engageable with each engageable portion at the control element to retain the movable member in a desired speed stage. The control element and retainer cooperate during shifting such that if a stroke of a control cable supported to the retainer is less than a given length, the retainer retains its engagement with each engageable portion, while if the stroke is greater than the given length, the retainer disengages from the engageable portion. A tension spring for stretching the cable and biasing the retainer in the direction of its disengagement from the engageable portions and an energy conservation spring for conserving energy when the cable is pulled to swing the retainer, are used to operate the movable member in rapid traverse-after the retainer disengages from the engageable portions.

摘要： In a device for shifting the drive chain on a multi-speed bicycle, a unit having a plurality of concentrically arranged different diameter chain wheels is secured on the axle of the bicycle's driven wheel. A chain trained over one of the chain wheels, passes over a chain guide wheel, and is rotatably supported on a movable support member. By displacing the chain guide wheel, the chain can be moved onto a selected chain wheel. A linkage arrangement is connected to the movable support member and to an adjusting switch for selecting one of the chain wheels. The linkage arrangement includes a first linkage part connected to the movable support member and a second linkage part articulated to the first linkage part so that the two parts are movable relative to one another. A cam disc is mounted on the second linkage part and a cam disc follower is mounted on the first linkage part. A readjustment spring forms a part of the guide device and acts on the first linkage part for maintaining the follower in contact with the cam disc.

摘要： A derailler for bicycles for moving the chain to sprocket wheels of varying diameters in which the control mechanism of the derailler includes a spring loaded linkage such that if the actuating cable is moved while the bicycle is not moving, the cable will not be subjected to stretching and breaking, but a spring loaded linkage allows the cable to move and exerts a spring bias on the derailler such that shifting occurs after the bicycle is placed in motion thus preventing injury and breakage to the mechanism.
