    Abstract: A device for bending an extremity of a torsional spring. The device includes a base plate; at least one flange projecting from the base plate; at least one bulge projecting from the at least one flange; a lever arm 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 has a contact surface 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 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 support 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.
