MOTORIZED INSTALLATION FOR MANEUVERING A SCREEN AND ASSOCIATED SCREEN DEVICE

摘要

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.

主权项

1. A motorized installation for maneuvering a screen having a first mobile end and a second opposite end, including;
at least two winding units positioned at the same one of the first or second end of the screen, wherein each of the two winding units includes a winding drum associated with a driving gear motor, the winding drums being guided so as to rotate mechanically independently of each other and an electronic control circuit including means for synchronizing the two winding units.
