Abstract: A device (1) for bending an extremity (3) of a torsional spring (5). The device includes a base plate (7); at least one flange (9) projecting from the base plate; at least one bulge (11) projecting from the at least one flange; a lever arm (13) pivotally mounted onto the at least one flange about a first pivot axis; and at least one cam pivotally mounted onto the lever arm about a second pivot axis. The lever arm is operable between first and second positions and each cam (15) has a contact surface (21) being positioned for operatively cooperating with a corresponding bulge. Prior to the bending operation, the extremity of the torsional spring is inserted between a given bulge and the contact surface (21) of a corresponding cam when the lever arm is in the first position. In operation, the extremity of the spring is bent about the given bulge by the contact surface of the corresponding cam when the contact surface is urged towards the bulge and forced about the same over the extremity of the spring as the lever arm is operated into the second position. The device enables an easier, simpler and more cost effective way of bending an extremity of a torsional spring, without the use of heat for bending the spring tail, and may be easily transportable from one site to another. Moreover, the device can be used for bending the extremities of torsional springs having different wire sizes.

Abstract: A winding system for winding a rolling door assembly. The winding system includes a support bracket, first and second gears. The suppart bracket is preferably rigidly connectable to a fixed structure of the rolling door assembly, and has a receiving device and a supporting device. The first gear is pivotally mounted about the receiving device of the support bracket and rotatable thereabout along opposite first and second directions of rotation. The second gear is pivotally mounted about the supporting device of the support bracket and rotatable thereabout along opposite first and second directions of rotation. The second gear is operatively connected to a corresponding end of the counterbalancing spring of the rolling door assembly and is also threadedly engaged with the first gear such that, a rotation of the first gear along one of its first and second directions of rotation causes the second gear to rotate along a corresponding one of its first and second directions of rotation, thereby resulting in a corresponding winding of the counterbalancing spring of the rolling door assembly.

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 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 chain keeper for retaining a chain operatively connected to a driving mechanism of a chain hoist system. The chain keeper has a support bracket an d a pair of plates. The support bracket is mountable onto a fixed structure, and has a substantially vertical longitudinal axis, and opposite top and bottom sections. Each plate has top and bottom portions. The plates project from the support brack et and are slanted with respect to the longitudinal axis thereof. The plates conver ge towards one another towards the bottom section of the support bracket, a slo t being defined between peripheral edges of the plates at the bottom section o f the support bracket. The slot is shaped and sized to slidably and removably receive therein a segment of the chain for retaining the same from substantial vertical movement along the longitudinal axis of the support bracket.

Abstract: A hydraulic governor device for use with a rotational shaft of a door assembly for controlling a rotation of said rotational shaft. The device includes a sleeve; first and second end coverings mounted respectively onto first and second ends of the sleeve so as to define an hydraulic flow path; a fluid substantially filling the hydraulic flow path; an input shaft extending through the ends coverings and the chamber, and being operatively connected to the rotational shaft of the door assembly; first and second pistons disks positioned inside the chamber and mounted about the input shaft, the pistons disks being connected to each other and being slidably movable along the input shaft; and a reciprocating assembly operatively connected between the input shaft and the piston disks and cooperating with the same for converting a rotation of the input shaft into a reciprocating movement of the pistons disks within a chamber, so that said reciprocating movement of the pistons disks inside the chamber causes in turn the fluid to travel along a reciprocating movement along the hydraulic flow path, said reciprocating movement of the fluid along the hydraulic flow path causing a damping effect of the rotation of the input shaft and thus controlling the rotation of the rotational shaft of the door assembly via a damping effect.

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).
