Abstract
A brake device for a cable-operated door operated by a tension cable, being mountable onto the cable-operated door and configured for cooperating with the tension cable so as to immobilize the cable-operated door with respect to the fixed structure by a braking arm in the event of a loss of tension in the cable. The brake device is provided with an anti-theft mechanism including a catcher assembly and a protrusion operatively projecting from the braking arm. The catcher assembly is operatively connectable to the fixed structure and the protrusion is shaped, positioned and sized with respect to the catcher assembly so as to be engaged with the catcher assembly when the braking arm is operated into the engaged configuration caused by a given loss of tension in the cable, thereby preventing the cable-operated door from being displaced upwardly along the fixed structure as a result of the catcher assembly abutting against the protrusion of the braking arm.
