Improvements to stacking panel shutter doors
In a torsion spring counter balancing mechanism 10 for a stacking panel shutter door, one end of the torsion spring 14 is fixable to a drive transmission shaft 13 of the door, the drive transmission shaft being adapted to raise and lower the shutter of the door. The other end of the spring is fixable to a separate rotatable member 15 of the mechanism. The mechanism is adapted to enable both the drive transmission shaft and the rotatable member to rotate, during opening and closing of the door, in such a manner as to cause respective ends of the spring to rotate in tandem in the same direction, but at different speeds during the opening and closing operation. This may be achieved via a reduction drivetrain 16, 17, 18, 23. The arrangement is stated to facilitate the use of a smaller size motor 26 than would otherwise be required.
