1. An automated louvre window system for a window opening, the system including:
- a. a plurality of louvre members;
b. a plurality of louvre end clips where each one of the plurality of louvre end clips is associated with a respective one of the plurality of louvre members;
c. a surround frame including a plurality of frame members, including a pair of U-shaped louvre gallery members, each louvre gallery member having a face wall through which the plurality of louvre end clips are mounted and a pair of side walls extending substantially perpendicularly thereto;
d. at least some of the plurality of louvre end clips each having a respective pivot member attached thereto and extending through at least one of the plurality of frame members; and
e. a drive mechanism for opening and closing the louvre members to cover and seal the window opening, the drive mechanism including a pair of substantially rigid operating bars adapted to open and close the louvre members by their movement, each of the substantially rigid operating bars having a first portion to abut a slide surface of a respective one of the pair of U-shaped louvre gallery members and a second portion extending substantially perpendicularly thereto with a number of engagement sections with one of the pair of operating bars provided on either side of the respective pivot member of each of the at least some of the plurality of louvre clips and engaged therewith, a substantially planar powered drive wheel, at least one substantially planar link member associated with both the wheel and at least one of the substantially rigid operating bars of the louvre window system, a plane defined by the respective first portions of each of the substantially rigid operating bars, the substantially planar powered drive wheel and the at least one substantially planar link member all being parallel to one another, the at least one link member having a first end attached pivotally but directly with the powered drive wheel and a second end attached pivotally but directly with at least one of the operating bars such that linear movement of the rigid operating bars decreases for a unit radial movement of the drive wheel during a period when increased load is experienced in a louvre opening sequence or closing sequence.

1. An automated louvre window system for a window opening, the system including:
-
a. a plurality of louvre members; b. a plurality of louvre end clips where each one of the plurality of louvre end clips is associated with a respective one of the plurality of louvre members; c. a surround frame including a plurality of frame members, including a pair of U-shaped louvre gallery members, each louvre gallery member having a face wall through which the plurality of louvre end clips are mounted and a pair of side walls extending substantially perpendicularly thereto; d. at least some of the plurality of louvre end clips each having a respective pivot member attached thereto and extending through at least one of the plurality of frame members; and e. a drive mechanism for opening and closing the louvre members to cover and seal the window opening, the drive mechanism including a pair of substantially rigid operating bars adapted to open and close the louvre members by their movement, each of the substantially rigid operating bars having a first portion to abut a slide surface of a respective one of the pair of U-shaped louvre gallery members and a second portion extending substantially perpendicularly thereto with a number of engagement sections with one of the pair of operating bars provided on either side of the respective pivot member of each of the at least some of the plurality of louvre clips and engaged therewith, a substantially planar powered drive wheel, at least one substantially planar link member associated with both the wheel and at least one of the substantially rigid operating bars of the louvre window system, a plane defined by the respective first portions of each of the substantially rigid operating bars, the substantially planar powered drive wheel and the at least one substantially planar link member all being parallel to one another, the at least one link member having a first end attached pivotally but directly with the powered drive wheel and a second end attached pivotally but directly with at least one of the operating bars such that linear movement of the rigid operating bars decreases for a unit radial movement of the drive wheel during a period when increased load is experienced in a louvre opening sequence or closing sequence. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An automated louvre window system for a window opening, the system including:
-
a. a plurality of louvre members; b. a plurality of louvre end clips where each one of the plurality of louvre end clips is associated with a respective one of the plurality of louvre members; c. a surround frame including a plurality of frame members, including a pair of U-shaped louvre gallery members, each louvre gallery member having a face wall through which the plurality of louvre end clips are mounted and a pair of side walls extending substantially perpendicularly thereto; d. at least some of the plurality of louvre end clips each having a respective pivot member attached thereto and extending through at least one of the plurality of frame members; and e. a drive mechanism for opening and closing the louvre members to cover and seal the window opening, the drive mechanism including a pair of substantially rigid operating bars adapted to open and close the louvre members by their movement, each of the substantially rigid operating bars having a first portion to abut a slide surface of a respective one of the pair of U-shaped louvre gallery members and a second portion extending substantially perpendicularly thereto with a number of engagement sections with one of the pair of operating bars provided on either side of the respective pivot member of each of the at least some of the plurality of louvre clips and engaged therewith, a substantially planar powered drive wheel, at least one substantially planar link member having a first end attached pivotally but directly with the substantially planar powered drive wheel and a second end attached pivotally but directly with at least one of the substantially rigid operating bars of the louvre window system such that linear movement of the rigid operating bars decreases for a unit radial movement of the drive wheel during a period when increased load is experienced in a louvre opening sequence or closing sequence, a plane defined by each of the respective first portions of the substantially rigid operating bars, the substantially planar powered drive wheel and the at least one substantially planar link member all being parallel to one another; an energy accumulation system including an energy accumulation portion and an energy storage portion, such that the energy accumulation portion collects or accumulates energy from a renewable source which is then stored in the energy storage portion, the energy storage portion releases at least a portion of the energy stored therein upon demand to the window opening and closing mechanism to open and close the automated louvre window system, wherein the drive mechanism is contained within the surround frame.
