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). The braking assembly includes a swivel component (18) having opposite braking arm (19) and lever portion (20), the lever portion cooperating with the tensioned cable (3) so that in the event of a loss of tension in the cable (5), the braking arm (19) is urged onto an adjacent rail (7) via biasing means (21) for anchoring a knife (45) of the braking arm (19) into the rail (7) and stopping, or at the very least, slowing down the descent of the door (3), with respect to the rail (7).
Abstract:
A brake device (1) for a cable-operated door (3) operated by a tension cable (5), being mountable onto the cable-operated door (3) and configured for cooperating with the tension cable (5) so as to immobilize the cable-operated door (3) with respect to the fixed structure (7) by means of a braking arm (19) in the event of a loss of tension in the cable (5), the brake device (1 ) being improved in that it is provided with an anti-theft mechanism (67) including a catcher assembly (69) and a protrusion (71) operatively projecting from the braking arm (19). The catcher assembly (69) is operatively connectable to the fixed structure (7) and the protrusion (71) is shaped, positioned and sized with respect to the catcher assembly (69) so as to be engaged with the catcher assembly (69) when the braking arm (19) is operated into the engaged configuration caused by a given loss of tension in the cable (5), thereby preventing the cable-operated door (3) from being displaced upwardly along the fixed structure (7) as a result of the catcher assembly (69) abutting against the protrusion (71 ) of the braking arm (19).
