Abstract
A hold and release mechanism for holding and releasing a cable includes a toothed-disk arrangement coupled with the cable take-up device for rotating together about a first axis. The toothed-disk arrangement includes a plurality of teeth at an outer periphery of the toothed-disk arrangement. The plurality of teeth includes locking and safety teeth. The locking catch engages with one of the locking teeth for holding the toothed-disk arrangement in a first rotational position. The safety catch engages with one of the safety teeth for holding the toothed-disk arrangement in a second rotational position.
Claims16
A bicycle shifter, comprising:
- a cable take-up device of a bicycle shifter for holding an actuation cable in a plurality of actuation positions with the cable take-up device, the plurality of actuation positions being stop and hold positions of the cable ranging from a maximum pull-out position to a maximum pull-in position, the hold and release mechanism;
- a cable hold and release mechanism configured for step-by-step releasing of the actuation cable in a release direction, the cable hold and release mechanism comprising:
- a toothed-disk arrangement coupled with the cable take-up device for rotating together about a first axis, the toothed-disk arrangement including a plurality of teeth at an outer periphery thereof, the plurality of teeth including locking and safety teeth, the locking teeth disposed in a first tooth plane orthogonal to the first axis, the safety teeth disposed in a second tooth plane that is orthogonal to the first axis and offset relative to the first tooth plane, and
- an adjustable locking pawl including locking and safety catches, the locking catch engaging with one of the locking teeth for holding the toothed-disk arrangement in a first rotational position, the safety catch engaging with one of the safety teeth for holding the toothed-disk arrangement in a second rotational position,
- wherein the maximum pull-out position of the plurality of positions corresponds to a maximum pull-out length of the actuation cable and is not achieved through engagement of the locking catch with a tooth.
