Abstract
A bicycle operating device comprises a base, an operating member, a hydraulic cylinder, a piston, a connecting link, and a guiding structure. The operating member is pivotally coupled to the base. The hydraulic cylinder is mounted to the base. The piston is movably provided in the hydraulic cylinder. The connecting link is pivotally coupled to each of the operating member and the piston to move the piston relative to the hydraulic cylinder in response to a pivotal movement of the operating member relative to the base. The guiding structure is coupled to the piston to guide the piston relative to the base.
Claims21
A bicycle operating device comprising:
- a base;
- an operating member pivotally coupled directly to the base;
- a hydraulic cylinder mounted to the base;
- a piston movably provided in the hydraulic cylinder;
- a connecting link pivotally coupled to each of the operating member and the piston to move the piston relative to the hydraulic cylinder in response to a pivotal movement of the operating member relative to the base;
- and
- a guiding structure coupled to the piston to guide the piston relative to the base, wherein
- the hydraulic cylinder includes a cylinder bore, and
- the piston includes
- a piston body movably provided in the cylinder bore, and
- a piston rod pivotally coupled to the piston body to operatively couple the connecting link to the piston body.
A bicycle operating device comprising:
- a base;
- an operating member pivotally coupled to the base;
- a hydraulic cylinder mounted to the base;
- a piston movably provided in the hydraulic cylinder;
- a connecting link pivotally coupled to each of the operating member and the piston to move the piston relative to the hydraulic cylinder in response to a pivotal movement of the operating member relative to the base;
- and
- a guiding structure coupled to the piston to guide the piston relative to the base, wherein
