Abstract
A device including a tube for winding and unwinding a screen which is controlled in rotation by a gear motor and which is supported on a fixed head and wherein a rotational part mounted within the tube is kinematically linked to rotate with the tube with the part including elements that are used to reflect a position of the rotational part and which elements are detected by senors that are connected to an electronic processing unit. A tightly sealed partition secured to the head is further provided to define, on one side, a first compartment for receiving at least the rotational part and, on the other side, a second compartment for receiving at least the electronic processing unit.

A device for driving a screen between open and closed positions relative to an opening, comprising a gear motor unit, a winding tube for displacing the screen and defining an inner chamber in which the gear motor is mounted, the winding tube being controlled in rotation about an axis by the gear motor unit, a head fixedly mounted on a support structure adjacent the opening and supporting the winding tube, a rotational part within the winding tube, drive means for rotating the rotational part in response to rotation of the winding tube, the rotational part including an element representative of a position and/or a displacement of the winding tube, sensor means for detecting the position and/or the displacement of the element, the sensor means being connected to an electronic processing unit adapted to determine the position and/or the displacement of the winding tube, a partition secured to the head and extending therefrom into one end of the winding tube, the partition defining, on one side toward the head, a first compartment in which the rotational part is mounted and, on another side, a second compartment in which at least the electronic processing unit is mounted, the partition sealing the second compartment so that the electronic processing unit is sealed relative to the first compartment and the rotational part, the partition including a first axial wall extending from the head inwardly within the one end of the winding tube toward the motor and a radial wall closing the first axial wall within the winding tube, and the first axial wall including at least one wall segment in which the rotational part is positioned.
A closure device for an opening in a building, wherein the closure device comprises a screen mounted to be wound upon a winding tube, a device for driving the winding tube to deploy or rewind the screen relative to the opening, a gear motor unit mounted within the winding tube for displacing the screen and defining an inner chamber in which the gear motor is mounted, the winding tube being controlled in rotation about an axis by the gear motor unit, a head fixedly mounted on the building adjacent the opening and supporting the winding tube, a rotational part within the winding tube, drive means for rotating the rotational part in response to rotation of the winding tube, the rotational part including an element representative of a position and/or a displacement of the winding tube, sensor means for detecting the position and/or the displacement of the element, the sensor means being connected to an electronic processing unit adapted to determine the position and/or the displacement of the winding tube, a partition secured to the head and extending therefrom into one end of the winding tube, the partition defining, on one side, a first compartment in which the rotational part is mounted and, on another side, a second compartment in which at least the electronic processing unit is mounted, the partition sealing the second compartment so that the electronic processing unit is sealed relative to the first compartment and the rotational part, the partition including a first axial wall extending from the head inwardly within the one end of the winding tube toward the motor and a radial wall closing the first radial wall within the winding tube, and the first axial wall including at least one wall segment in which the rotational part is positioned.
