Abstract:
In order to control the light or air permeability of an elastic extensible screen (1) disposed between an area to be protected and an external area, and having a permeability that varies with a pulling force exerted on the screen, a motorized mechanism (3) adjusts the pulling force on the screen in response to a setpoint signal, which can be determined on the basis of one or a plurality of signals from one or a plurality of sensors (12, 14, 15), in particular light sensors.
Abstract:
A motor-driven carriage (100) for opening/closing a curtain, includes a housing (110) that is provided with two members (124, 126) for suspending the housing from a rail (50), wherein a friction wheel (112), which is driven by an electric motor and which is to contact at least one rolling surface (56, 57) of the rail, is rotatably mounted inside the housing. The carriage (100) also includes a cradle (150) provided with two other members (155, 156) for suspending the cradle from the rail (50), which are separate from the members (124, 126) for suspending the housing (110), as well as elements (153, 154) for coupling to the curtain. The cradle is mounted onto the housing (110) and is driven by the housing when the latter moves along the rail, the housing (110) and the cradle (150) optionally being capable of relative movement there between.

Abstract:
The invention relates to a screen device (10) comprising a screen (16) movable between a retracted position and a deployed position, bearing on a load bar (12), and motorized by an installation comprising at least two winding units (24), each comprising a winding coil (26) associated with a driving gear motor (28), the winding coils (26) being guided to rotate relative to the box (18) mechanically independently from one another. A control circuit (32) synchronizes the two winding units (24) by driving each gear motor (28) so as to ensure the horizontal position of the load bar. To that end, the control circuit (32) is connected to one or more sensors (34), for example accelerometers, delivering a signal representative of the levelness of the load bar.
