Abstract: An insulating glazing unit internally provided with a blind which is adapted to be moved from a fully gathered condition to an unfolded condition, and vice versa. The blind, in the gathered configuration, is arranged in the lower part and interacts with an arrangement for pulling a flap in order to unfold it from the bottom upward until the insulating glazing unit is fully blacked out.

Abstract: An actuation assembly in a double-glazing unit with a perimetric frame which supports two glass panes which form, between them, a sealed air space which accommodates a light blocking blind which is adapted to be orientated and/or moved from a fully packed or rolled-up condition to unfolded conditions and vice versa. The actuation assembly has a rotor which is arranged between the panes, is connected so as to rotate together with an actuation shaft of the light blocking blind, and is provided with one or more permanent magnets which are arranged with alternating polarities, and at least two electromagnets which are arranged so that when they are crossed by an electric current they generate respective magnetic fields whose polarities can vary according to the direction of the current and are arranged on corresponding angular positions with respect to the rotor.

Abstract: An actuator device connected with a blind arranged inside a hermetically sealed space of a double-glazing unit. The double-glazing unit has a pair of parallely extending glazed plates between which the hermetically sealed space is arranged, and a sealant layer extends perpendicularly between the glazed plates. The actuator device includes a first magnet which is arranged inside the hermetically sealed space, and a second magnet which is arranged externally of the hermetically sealed space. The first magnet is directly connected to a first part of the actuator device arranged inside the hermetically sealed space for actuating the blind dependent upon a sliding motion of the first magnet, and the second magnet is connected to a second part of the actuator device accessible outside of said hermetically sealed space to an operator for sliding the second magnet outside said hermetically sealed space.

Abstract: An actuation device for a Venetian blind or the like arranged inside a double-glazing unit comprises a first magnet, which is arranged inside the double-glazing unit and is directly connected to the respective actuation system, and a second external magnet. The second magnet is associated, in a box-like structure which is applied horizontally on the outside of the double-glazing unit, with a kinematic element extending between two end elements, one of which is arranged on an actuation rod which can rotate about its own axis.

Abstract: A device, particularly for compensating the internal and external pressures in a double-glazing unit, such double-glazing units comprising a frame which supports two sheets made of at least partially transparent material, a chamber being formed between the two sheets and being adapted to provide an air space for thermal and acoustic insulation. The device comprises a duct which connects the inside of the chamber to the outside environment and is shaped so as to form two siphons arranged in series, a first siphon, located towards the chamber, having a higher head than a second siphon, located towards the outlet of the duct into the outside environment, the device further comprising elements for absorbing the moisture of the air contained in the portion of duct between the siphons.

Abstract: Device for compensating pressure differences between the inside and the outside of an insulating glass frame, including a closed cylindrical hollow body which is arranged, so that its axis is not horizontal, between the inside and the outside of an insulating glass frame. A ball is movable within the body and has such a diameter as to be in contact with the wall, so as to fully separate the inside into two regions. At least one first hole for connection to the outside/inside is located in a suitable wall portion affected by the passage of the ball, and at least one second hole for connection to the inside/outside is located on the bottom.

Abstract: Motorized actuation device for a Venetian blind or the like placed inside an insulating glass frame including a first magnet, arranged inside the insulating glass frame and directly connected to the respective actuation system, and a second external magnet, the second magnet being associated with the translatory part of a kinematic system for converting the rotary motion into a translatory motion, and the kinematic system being connected to an actuation gearmotor.
