Abstract:
1. A brake pad mechanism for an upward acting door, the door disposed between a pair of parallel tracks, the tracks having a vertical portion connected to a horizontal portion by curved portion, the door movable along the tracks between the open and closed positions, the brake pad mechanism comprising: a main body member coupled to the movable barrier, the main body member having a slot to receive a first and second brake pad support disposed within and engageable with at least one of the parallel tracks, wherein the first brake pad support moves away from the second brake pad support when moving to a braking position; a reset link engageable with a biased tensioning arm to position the first and second brake pad supports in a retracted position; a cable follower secured to the tensioning arm, the cable follower configured to receive a support cable; and wherein the tensioning arm is pivotable in response to movement of the door along the curved portion such that the reset link maintains engagement with the tensioning arm as the door travels along the curved portion to the open position; and wherein the tensioning arm further includes a curvilinear slot to receive a cam follower disposed on a lateral end of the reset link opposite a first biased connection of the reset link to the main body member, wherein the curvilinear slot at least partially encircles a second biased connection between the tensioning arm and the main body member, the cam follower movable within the curvilinear slot in response to movement of the tensioning arm.
