摘要： A shift lever apparatus for use in bicycles comprising first and second ratchet wheels and first and second switch levers, all of them being mounted on a main shaft. The first and second switch levers contain first and second ratchet pawls for engaging with the first and second ratchet wheels, respectively. The first and second ratchet wheels are connected to a cam via a gear set so as to cause the cam to rotate in forward and reverse directions, respectively. The outer periphery of the cam consists a plurality of spiral sectors, each of which having monotonically increasing radius, alternated with a plurality of circular sectors, each of which having constant radius. When a follower, which is provided in the shift lever apparatus, is in contact with one of the spiral sectors, a movement of the first or the second lever will cause the cam to rotate, in a forward or reverse direction, and the follower to pull or release the shifting cable according, thus allowing the derailleur to shift gear upward or downward.

摘要： An improved rear derailleur for changing the gear ratio of a bicycle is disclosed. It includes a fixed member, a movable member, a parallelogram mechanism connecting the fixed member with the movable member, and a cable adjusting screw which is screwed to a screw socket fixed on the fixed member. The cable adjusting screw is connected to a first end of a cable, wherein the cable has a second end fixed to a movable member. The cam member comprises a guiding surface for guiding the cable between the cable adjusting screw and the movable member. The guiding surface of the cam member is structured substantially coinciding a portion of a fictitious circle centered at a rotating pin which connects an outer linkage of the parallelogram with a second end of the fixed member. Furthermore, the cable adjusting screw is positioned in such a manner that its extension is always substantially tangential to the guiding surface of the cam member, so as to allow the cable to be pulled in a direction substantially coincident with the axial extension of the cable adjusting screw.

摘要： The present invention relates to a bicycle speed change lever apparatus which is mounted near the handlebar of a bicycle. A lever apparatus is used for pushing a ratchet member, allowing the ratchet member to produce a positive or negative rotation, which further drives a cable-pulling member, thus allowing the cable to be tightened or relaxed by the cable-pulling member to accomplish an in or back shift. A position maintaining mechanism is also provided for effectuating the shift change, and the cable is allowed to maintain a certain amount of tension. The speed change lever apparatus eases the shifting operation and makes the in shift or back shift more precisely controlled.

摘要： A multiple sprocket assembly for use in a bicycle comprising: (1) at least a large sprocket wheel and a small sprocket wheel, each of the large and small sprocket wheels having a plurality of teeth on an outer edge thereof, and the large sprocket wheel having more teeth than the small sprocket wheel; (2) each of the sprocket wheels being adapted to engage with a chain guided by a derailleur; the chain comprising a plurality of rollers connected in series by link plates. The multiple sprocket assembly is characterized in that the small sprocket wheel has at least two consecutive teeth, each with a portion of its side surface trimmed off, and the large sprocket wheel has at least three consecutive teeth each also with a portion of its side surface trimmed off, so as to avoid interference between the link plates and the large sprocket when the chain is being shifted from the small sprocket to the large sprocket. In a preferred embodiment, at least two of the trimmed portions on the small sprocket are formed on the first distal side surface, and the trimmed portions on the large sprocket contain at least two trimmed portions on the second distal side surface and at least one trimmed portion on the second proximal side surface. The side surfaces of the teeth of the small sprocket are trimmed in such a manner such that the escape roller will not be immediately lifted up, but will be pushed laterally as a result of the trimmed portions of the small sprocket. The side surfaces of the teeth of the large sprocket are trimmed in such a manner such that one of the surfaces contains an axially extending portion, which serves as a fulcrum for the engage roller to be pivotally engaged with the large sprocket.
