Abstract: 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.

Abstract: 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.

Abstract translation: 用于由拉紧的电缆操作的电缆操作门的电缆故障装置，电缆操作的门具有沿固定结构（例如导轨）引导的运动。 电缆故障装置被配置为与张紧的电缆配合，以便在电缆中的张力损失的情况下使电缆操作的门相对于固定结构固定。 电缆故障装置包括用于将电缆故障装置安装到门上的支撑支架，可操作地安装以用于引导门沿着固定结构的移动的引导组件，以及可操作地安装在支撑支架上的制动组件， 允许引导组件沿着固定结构引导门的静止位置，以及由张力电缆中检测到的给定的张力而触发的可操作位置，其中制动组件接合固定结构的一部分以制动电缆的运动 相对于固定结构的门。 电缆故障装置还包括可操作地连接到制动组件并与张紧的电缆配合以便检测给定的张力损失的安全臂。 安全臂可在安全构型之间操作，当安全构型位于支撑支架的相应孔的至少一个紧固件上时，在张紧的电缆中仍然具有给定的张力时，用于防止使用者从门上移除支撑托架 以及当给定的张力不再存在于电缆中时安全臂远离紧固件定位的缩回构型，从而使得使用者能够进入紧固件。 因此，电缆故障装置被配置为在失去张力的情况下固定门，并且当电缆中仍然存在张力时防止用户从门上移除设备。
