摘要： A cable failure device for a cable-operated door operated by a tensioned cable, the cable-operated door having a movement guided along a fixed structure, such as a guide rail. The cable failure device is configured for cooperating with the tensioned cable so as to immobilize the cable-operated door with respect to the fixed structure in the event of a loss of tension in the cable. The cable failure device included a support bracket for mounting the cable failure device onto the door, a guiding assembly operatively mounted for guiding the movement of the door along the fixed structure, and a braking assembly operatively mounted onto the support bracket, and operable between a rest position where the guiding assembly is allowed to guide the door along the fixed structure, and an operable position triggered by a given loss of tension detected in the tension cable where the braking assembly engages a portion of the fixed structure for braking movement of the cable-operated door with respect to the fixed structure. The cable failure device also includes a safety arm operatively connected to the braking assembly and cooperating with the tensioned cable so as to detect the given loss of tension. The safety arm is operable between a safety configuration where it is positioned over at least one fastener of a corresponding hole of the support bracket when there is still a given tension in the tensioned cable, for preventing a user from removing the support bracket from the door, and a retracted configuration where the safety arm is positioned away from the fastener when the given tension is no longer present in the cable, thereby enabling the user access to the fastener. Thus, the cable failure device is configured for immobilizing the door in the event of a loss of tension and for preventing a user from removing the device from the door when there is still tension in the cable.

摘要： A safety braking device configured for use with the counterbalancing system of a garage door. The safety braking device includes a support bracket, a ratchet wheel, a pawl arm, and a biasing spring. The support bracket is rigidly connected to a fixed structure and has a guiding slot. The ratchet wheel is securely mounted about the overhead shaft of the counterbalancing system and has at least one notch. The pawl arm has first and second ends, the first end of the pawl arm being pivotally connected to the support bracket and the second end of the pawl arm cooperating with the guiding slot and being movable with respect to the support bracket along said guiding slot. The first and second ends of the pawl arm are further connected to flanges of a plug on either side of the overhead shaft. The biasing spring is operatively connected between the support bracket and the pawl arm so as to exert a biasing force for biasing the pawl arm towards the ratchet wheel. The pawl arm is devised so that, an element thereof is adjacent to the ratchet wheel, said element being shaped and sized to be removably insertable into at least one notch of the ratchet wheel so as to block rotation of the ratchet wheel, and thus block rotation of the overhead shaft, in the event of a failure of the counterbalancing system of the door.
摘要翻译：一种配置成与车库门的平衡系统一起使用的安全制动装置。安全制动装置包括支撑托架，棘轮，棘爪臂和偏置弹簧。支撑支架刚性地连接到固定结构并具有引导槽。棘轮被牢固地安装在平衡系统的顶部轴上并且具有至少一个凹口。棘爪臂具有第一和第二端，棘爪臂的第一端枢转地连接到支撑托架，并且棘爪臂的第二端与引导槽配合并且可沿着所述引导槽相对于支撑托架移动。棘爪臂的第一端和第二端进一步连接到顶置轴的任一侧上的插头的凸缘。偏置弹簧可操作地连接在支撑支架和棘爪臂之间，以便施加用于将棘爪臂朝向棘轮偏压的偏置力。棘爪臂被设计为使得其元件与棘轮相邻，所述元件的形状和尺寸被设计成可拆卸地插入到棘轮的至少一个凹口中，以阻止棘轮的旋转，并因此阻挡在门的平衡系统发生故障的情况下，顶置轴的旋转。
