Patent ID: 7568558

Claim:
A bicycle brake apparatus adapted to be mounted to a bicycle frame, wherein the apparatus comprises: a securing bracket with an axle opening dimensioned to receive a bicycle wheel hub axle therethrough; a braked member that has a braking surface and is adapted to rotate with a bicycle wheel hub rotatably supported by the hub axle; a braking member adapted to contact the braking surface; an operating unit including an actuating arm that selectively causes the braking member to contact the braking surface in response to rotation of the actuating arm; and a locking unit structured for attachment to the securing bracket, wherein the locking unit extends in an axial direction of the hub axle and is dimensioned to nonrotatably engage the bicycle frame radially inwardly of a rotating portion of the brake apparatus; wherein the locking unit is coupled to the braking member to prevent the braking member from rotating around the axle opening; wherein the actuating arm is disposed axially between the locking unit and the braking member so that the actuating arm rotates relative to the locking unit and the braking member; wherein the locking unit comprises first and second bent tabs locking members extending in a same axial direction of the hub shaft, disposed radially outwardly from the axle opening and dimensioned to be inserted both at the same time into a hub axle mounting slot formed in the bicycle frame; wherein the axle opening is disposed between the first and second bent tabs locking members so that, when the bicycle brake apparatus is mounted to the bicycle frame, the hub axle and the first and second bent tabs locking members all are disposed within the hub axle mounting slot and are sandwiched between frame portions that form the hub axle mounting slot.
