Embodiment Construction

[0081] To get started see figure 1 - 3. A bicycle 10 is shown with a front (first) shift operating device 20 and a rear (second) shift operating device 22 according to a preferred embodiment of the present invention. The bicycle 10 basically includes a frame 12 , a drive train or transmission 14 , a front wheel 16 and a rear wheel 18 . Frame 12 includes a handlebar 13 pivotally coupled thereto. Specifically, the handlebar 13 is fixedly coupled to the front fork of the frame 12 for driving the bicycle 10 through the front wheel 16 . The transmission train or transmission 14 includes a front derailleur 15, a rear derailleur 17, a chain C, a plurality of rear sprockets RS coupled to a rear wheel 18, and a rear sprocket RS with a plurality of front sprockets FS coupled thereto. The front crank FC. Front and rear derailleurs 15 and 17 are coupled to the frame 12 for moving / shifting the chain C laterally between the respective sprockets FS and RS in a more conventional manner. F...

Abstract

A bicycle shift operating device basically includes first operating member operatively coupled to a winding mechanism by a follower link and an operating link. A second operating member is also preferably operatively coupled to the winding mechanism. The cable winding mechanism is mounted on a first pivot axle and is configured to be selectively retained in a plurality of shift positions. In one shift operating device, the operating link is pivotally mounted on the first pivot axle. In an alternate shift operating device, the operating link is pivotally mounted on a second pivot axle that is spaced from the first pivot axle and parallel to the first pivot axle. The first operating member is preferably arranged to reciprocate in a first direction. The second operating member is preferably arranged to move in a second direction that is substantially parallel to the first direction.

Description

technical field [0001] The present invention generally relates to a bicycle shift operating device. More specifically, the present invention relates to a shift operating device in which a shift lever moves in a generally parallel direction. Background technique [0002] Cycling is becoming an increasingly popular form of recreation as well as a mode of transportation. Moreover, cycling has become a very popular competitive sport among both amateurs and professionals. Whether the bicycle is used for recreational, transportation or competitive purposes, the bicycle industry is constantly improving the various components of the bicycle. One part of the bicycle that has been extensively redesigned is the bicycle transmission. Specifically, bicycle transmissions typically include front and rear shifting mechanisms designed to operate front and rear derailleurs to move the derailleurs laterally over a plurality of sprockets. A sprocket is usually coupled to the front crank and...
