Abstract: The present disclosure concerns a system for driving a Venetian blind comprising a blind assembly which comprises a Venetian blind, an electric motor for actuating the movement of said Venetian blind and first electronic means configured to generate a drive signal for driving said electric motor; a control unit having drive means for driving the movement of said Venetian blind, a power source for generating a current signal to power said electric motor and second electronic means that are in signal communication with said drive means and with said power source for controlling said electric motor; a two-wire power line disposed between said control unit and said blind assembly to power said electric motor with said current signal and the first electronic means are in signal communication with said second electronic means via said two-wire power line.

Abstract: The invention refers to a system comprising a Venetian blind or the like housed within a double glazing or a double glass. The blind comprises a multiplicity of slats movable by means of a shaft rotatable around a longitudinal axis thereof and housed in a rolling-shutter box of the double glazing. The closure system comprises means for rotating the shaft around the longitudinal axis thereof. The rotation means are housed in a lateral profile of the double glazing and are commanded by a slider translatable between an upper end stop, at which the blind is completely raised, and a lower end stop, at which the blind is completely lowered. The closure system further comprises a first mechanism which prevents a movement of the blind until, during the transport or assembly of the closure system, the rolling-shutter box is disconnected from the lateral profile.

Abstract: A spacer profile for an insulating glazing unit for maintaining a space between glazing panes includes a profile body formed from a first heat insulating material that has, viewed in a cross section perpendicular to a longitudinal direction, outer side walls extending in a height direction and that has a distance in a transverse direction smaller than a first width, each side wall having an inner protrusion protruding towards the opposite side wall into a recess which is open to the inner side, and a diffusion barrier film made from a second material and firmly bonded with the profile body and, viewed in the cross section perpendicular to the longitudinal direction, extending over the profile body on the outer side of the spacer profile and continuous thereto in the height direction on the outside of the side walls and/or in the same to a second height and into the protrusions.

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: A double glazing system, including a first sheet of glass, a second sheet of glass, a spacer element including a first surface for coupling with the first sheet of glass and a second surface for coupling with the second sheet of glass, a blind, or a screen, said spacer element made from low thermally conductive material including rubber and/or silicone foam. The spacer element includes support means including a housing made of a substantially “T”-shaped groove made on a surface perpendicular to the first surface and to the second surface. The support means include two lateral sections for guiding said blind, screen or the like having respective substantially “T”-shaped portions and being able to be engaged in said housing, the lateral sections including respective free ends for supporting respective end portions of said blind, screen or the like.

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.
