  • Spurring device capable of accelerating the speed of a bicycle upon release of the bicycle from a braked state
    Patent number: 6139036
    Abstract: A spurring device includes a carriage lever pivoted on a mounting frame around a pivot axis parallel to a rotating axis of a rear sprocket wheel of a bicycle. The carriage lever has a front lifted portion and a rear depressed portion opposite to each other relative to the pivot axis. The front lifted portion is adapted to be pulled by a manually operated brake cable to move upwards to bring the rear depressed portion towards a rear tire of the bicycle. A rear axle is rotatably mounted on the rear depressed portion around a rotating axis parallel to the pivot axis. A frictional rotary member is mounted on and is rotatable with the rear axle to frictionally engage the rear tire when the rear depressed portion is brought towards the rear tire so as to be driven together with the rear axle to rotate clockwise. Simultaneously, a first biasing member is disposed on the rear axle to accumulate a biasing force for urging the rear axle to rotate counterclockwise.
