Abstract:
1. 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, the fixed structure having an inner portion and an outer portion, the cable failure device being mountable onto the cable-operated door and being 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 comprising: a support bracket mountable onto a bottom portion of the cable-operated door, the support bracket comprising: a guiding assembly operatively mounted onto the support bracket for guiding the movement of the cable-operated door along the fixed structure, the guiding assembly travelling along the inner portion of the fixed structure; a braking assembly operatively mounted onto the support bracket, the braking assembly being operable between a rest position where the guiding assembly is allowed to guide the cable-operated door along the fixed structure, and an operable position triggered by a given loss of tension detected in the tensioned 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; and a safety arm operatively connected to the braking assembly and cooperating with the tensioned cable so as to detect said given loss of tension, the safety arm being operable between a safety configuration where it is positioned over at least one fastener of said at least one 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 cable-operated door, and a retracted configuration where the safety arm is positioned away from said at least one fastener when said given tension is no longer present in the cable, thereby enabling the user to access said at least one fastener.
