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 means of a braking arm in the event of a loss of tension in the cable, the brake device being improved in that it 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.

Abstract: A device (1) for use with a cable-operated door (3), such as garage doors (3) and the like, and a door assembly including the same. The device (1) is intended to reduce the risk of the door (3) falling, or at the very least slow down its descent, in the event of a failure in the counterbalancing mechanism of the door (3), which is generally represented by a loss of tension in a given tensioned cable (5) operating the door (3). The brake device (1) includes a support bracket (9), and a guiding assembly 15 and a braking assembly 17 mounted onto the support bracket (9).
