A bicycle operating apparatus is provided with a base member, a ratchet, a pawl member and an operating member. The ratchet is rotatably disposed around a ratchet axis, and biased in a first direction about the ratchet axis. The operating member moves the pawl member from a first position to a second position. The pawl member has a pawl portion and first and second support portions. The pawl portion engages with the ratchet teeth while the pawl member is in the second position to regulate rotation of the ratchet in the first direction. The first support portion pivotally supports the pawl member around a first axis as the pawl member moves from the first position to the second position. The second support portion pivotally supports the pawl member around a second axis while the pawl member is in the second position.

A pawl carrier system comprising a pawl hub disposed substantially coaxially to a pawl carrier, a spring circumferentially disposed between the pawl hub and the pawl carrier, a pawl pivotably mounted to the pawl hub on a pivot joint, the pivot joint comprising an axially extending pin mounted to the pawl hub, wherein the axially extending pin extends through the pawl carrier and the pawl hub. A ratchet carrier system is provided comprising a ratchet carrier disposed substantially coaxially to a ratchet hub, wherein the ratchet hub comprises a ratchet tooth, a spring circumferentially disposed between the ratchet carrier and the ratchet hub and a retaining pin axially extending through the ratchet carrier and the ratchet hub.

The invention relates to an actuation device (1) for a parking brake and is comprised of a parking brake lever (2) swivel-mounted on a bearing block (3) and a blocking device by means of which the parking brake lever (2) can be fixed in place in a swivel position on the bearing block (3). The blocking device has a locking segment (11) that is connected to the bearing block (3) and a pawl (12) mounted on the parking brake lever (2). The bearing block (3) and the locking segment (11) are designed to be one piece and are made of a die-cast part or an injection-molded part.

A parking brake control assembly having a brake actuator includes an engagement member, a retention member, a release actuator, and a biasing member. In a first position of brake actuator, the retention member is arranged to engage the engagement member upon movement of the brake actuator from a first position to a second position to hold the brake actuator in the second position. Movement of the brake actuator from the first to the second position causes the release actuator to move relative to the retention member such that the biasing member provides a force on the retention member tending to disengage the retention member from the engagement member so that upon movement of the brake actuator to return the brake actuator from the second position to the first position, the retention member disengages from the engagement member enabling the brake actuator to be returned to the first position.
