    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 sl ow down its descent, in the event of a failure in the counterbalancing mechanis m 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 ra il (7).

    Abstract: A plug mounted at one end of a torsional spring operatively connected to an overhead shaft of a counterbalancing mechanism of a garage door, wherein the plug comprises projecting interlocking means able to cooperate with corresponding matching means of a mating part of the counterbalancing mechanism, so that when the interlocking means of the plug are inserted into the corresponding matching means and when tension is applied to the torsional spring, the interlocking means interlock with said matching means of the mating part, thereby preventing the plug from being readily removed therefrom. The projecting interlocking means thus act as safety means because they provide an automatic locking mechanism which make the plug operate as a safety device as well. Hence, the plug according to the present invention has a dual purpose, that is, it can operate as a conventional plug, whether it be stationary or winding, as well as a safety device for the counterbalancing mechanism with which it cooperates, because of its projecting interlocking means.

    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: A security seal for a collar used for tensioning springs in garage door assemblies. A collar typically includes at least one set screw projecting outwardly and at least two winding holes. The security seal of the invention includes a generally longitudinal piece of flexible material having two opposite ends, the opposite ends being provided with a locking system for locking the opposite ends together in a permanent fashion. The seal also has at least one hollow cup adapted to receive the at least one set screw and at least two solid cups, each of the cups being adapted to fit with a corresponding winding hole. The hollow cup and the at least two solid cups are disposed on the security seal so that wh en the seal is locked above the collar, the hollow cup and the solid cups are in registration with the at least one set screw and the at least two winding holes respectively.
