    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 plug for use in a counterbalancing mechanism of a cable-operated door . The plug is mounted about an overhead shaft and used for operatively connecting the overhead shaft to a torsion spring coaxially mounted thereon. The plug includes a cylindrical collar and a cylindrical flange. The cylindrical coll ar has opposite first and second portions. The collar is provided with a hooking sl ot for hooking a free end of the torsion spring therein and the torsion spring has a segment coaxially mounted about the first portion of the collar. The cylindrical flange is rigidly affixed to the second portion of the collar. The flange is used for transferring a torque between the torsion spring and the overhead shaft when the flange is securely fixed about the overhead shaft. The plug further includes a shouldering floor of a given length faced against the hooking slot and extending inside the collar, from the second portion towards the first portion thereof , between the collar and the overhead shaft.

    Abstract: A plug for operatively connecting a torsion spring onto a corresponding component of a counterbalancing mechanism of a door assembly. The plug includes a connecting portion for removably connecting the plug onto the corresponding component, a substantially cylindrical collar insertable into an end portion of the torsion spring, an anchoring portion disposed on a bottom section of the collar for cooperating with a coil of the end portion of the torsion spring so as to pivotally anchor the collar onto the end portion of the torsion spring, and a clip projecting from a top section of the collar, and being disposed at a location on the collar substantially diametrically opposite from where the anchoring portion is disposed on the bottom section of the collar. The clip is shaped and sized for clasping past an end coil of the torsion spring and operatively engaging with the same so as to securely mount the plug onto the end portion of the torsion spring in a clip-like manner, thereby enabling the plug to be mounted onto the torsion spring quickly and easily.

    Abstract: A ratchet-like system for winding a rolling door assembly. The ratchet- like system includes a support bracket, a cam, and a biasing device. The support bracket is preferably mounted onto a fixed structure of the rolling door assembly. The cam is pivotally mounted about the support bracket and positioned adjacent to a portion of an overhead shaft of the assembly. The cam is shaped and sized to cooperate with this portion of the overhead shaft between a first position, where the cam allows rotation of the overhead shaft along a first direction, and a second position, where the cam has a surface engaged with the overhead shaft and where further rotation of the overhead shaft along a second direction, opposite to the first direction, is blocked by the cam. The biasing device is used for urging the surface of the cam onto the overhead shaft. The ratchet-like system is particularly useful for adjustably controlling the rotation of the overhead shaft of the rolling door assembly during the winding thereof.
