摘要: A cable failure device for a mobilizing a garage door in the event of a failure of one of the cables or one of the elements holding the cables is described. The cable failure device of the invention includes a support structure mounted on the cable operated door and includes a connection point onto which a tensioned cable is connected. A braking assembly is mounted onto the support structure and includes a casing mounted onto the support structure and a brake operable between a rest position and an operable position. The brake is movably mounted to the support structure and is located adjacent the outside of a fixed frame such as guide rails and is adapted to co-operate with a roller on the garage door so that a portion of the guide rail lies between the roller and the brake. A tension detector co-operating with the tension cable is provided for detecting a tension in the tension cable and an actuator is operatively connected to the tension detector and to the brake. When the brake is in the rest position, the rollers guide the door along the rail and when the brake is triggered into the operable position by a loss of tension in the cable detected by the tension detector, it causes the actuator to actuate the brake so that it engages the outside of these rails, thereby urging the brake and one of the rollers towards each other. This combined action brakes the movement of the cable operated door and thus impedes its free falling to the ground, thereby preventing damages and injuries.
