Abstract
A bicycle control device is configured with an operating member, a hydraulic braking unit and a shifting unit. The operating member is configured in the preferred embodiment to operate both the hydraulic braking unit and the shifting unit. The shifting unit is movably disposed around a center cylinder axis of a hydraulic brake cylinder to provide a compact structure. Also the operating member is configured to perform braking and speed change operations such that the braking operation is carried out without movement of the parts of the shifting unit.
Claims18
A shift and brake control device comprising:
- an operating member configured and arranged to perform a braking operation when moved along a braking path;
- a hydraulic braking unit including a hydraulic brake cylinder with a center cylinder axis, the operating member being configured to operate the hydraulic braking unit;
- and
- a shifting unit being movably disposed around the center cylinder axis of the hydraulic brake cylinder, the shifting unit including a wire take up member being movably disposed around the center cylinder axis of the hydraulic brake cylinder.
A shift and brake control device comprising:
- an operating member configured and arranged to perform a braking operation when moved alone a braking path;
- a hydraulic braking unit including a hydraulic brake cylinder with a center cylinder axis, the operating member being configured to operate the hydraulic braking unit;
- and
- a shifting unit being movably disposed around the center cylinder axis of the hydraulic brake cylinder, the operating member being operatively coupled to the shifting unit to perform a shifting operation when moved along a shifting path,
- the braking path lying in a plane that is perpendicularly arranged relative to a plane containing the shifting path.
A shift and brake control device comprising:
- a mounting portion including tubular clamping surface extending around a central axis;
- an operating member configured and arranged on the mounting portion to perform a braking operation when moved along a braking path and a shifting operation when moved along a shifting path;
- and
- a shifting unit configured and arranged on the mounting portion to be operated in response to the shifting operation by the operating member, and the shifting unit including a wire take-up member that is rotatable about an axis transverse to the central axis in response to movement of the operating member along the shifting path and that remains stationary relative to the mounting portion in response to the braking operation by the operating member.
