  • Patent number: 8342224
    Abstract: An architectural louver shade assembly comprising a shade canopy mounted to a rotatable central axle tube that supports a rod rib assembly to which the shade canopy is attached by adjustable tensioners that mechanically stretch and tension the fabric element of the shade canopy to remove wrinkles and sags. A wax cylinder piston attached by elements of a wax piston pressure system that changes the pitch of the shade canopy in response to temperature with a gas spring unit that returns the shade canopy to its default, horizontal orientation with decreasing temperatures. An optional manual/mechanical system that, through use of control cables, changes the pitch of the shade canopy with a gas spring unit that returns it to a default orientation. A camber cable assembly that maintains an equal compression load on the rib arm units that directly support the shade canopy, and carrier brackets that support the central axle tube and connect the louver shade assembly to a building wall.
