Abstract: A device for actuating a curtain/awning in a double glazing includes a pulley supported by support elements connected to connection elements integrally connected to a wall of the double glazing at the movement group. A ring of cord is partially wound around the pulley and is maintained taught by a tensioning element, it too connected to the wall of the double glazing. By applying a tension to the cord ring, a torque is generated tending to rotate the pulley. The torque is transmitted by suitable transmission elements to the group for moving the curtain/awning. The support elements of the pulley are separated from the connection elements for values of tension applied to the cord ring that are greater than a pre-established limit value. The separation cancels the tension of the cord.

Abstract: Inside a glass-enclosed chamber is a Venetian blind connected to internal elements for operating it, the elements being workable from outside to raise, lower and incline the slats. The raw slats of the blind are obtained by moulding a rolled strip of aluminum alloy hardened by magnesium. The strip has not been lapped in order to maintain a degree of roughness on both surfaces, ready to receive a reflecting layer. Reflective stratification includes a layer of pure aluminum adherent to the body of the slat that serves to fix a reflective type of interferential dielectric multilayer. Average thickness of the layer of sputtered aluminum depends on the diffusivity of reflected radiation required in relation to the maximum height of the peaks of surface roughness on the body of the slats. Useful multilayers increase reflectance to levels averaging over 85% on a wide interval of wavelengths from near infrared to ultraviolet.
