An actuator for opening and closing a closure including a motor, a sprocket rotated by the motor, and a chain driven by the sprocket and having a first end connected to the closure and a second end positioned within a casing. The actuator also includes a support mounted so as to reciprocally movable relative to the sprocket and having a guide through which a portion of the chain is movable so that the movement of the support is due to the chain being driven by the sprocket.

The actuator (1) of the invention includes a motor (8), a sprocket (8) rotated by the motor, and a chain (4) driven by the sprocket (3) and having a first end (41) to be connected to opening (F) to be actuated. The actuator (1) also includes a bearing (5) for a portion (45) of the chain (4), said bearing being mounted so as to be capable of free translation along an axis (X2) perpendicular to rotation axis (X3) of the sprocket (3) and being provided with means (6) for interaction with the chain so that the translation movement of the bearing along the axis (X2) is due to the chain (4) being driven by the sprocket (3).

Each screen (1) of a group of screens is configured by a method in which a function is approximated, the function giving the instantaneous axial position (H(t)) of the load bar (2) thereof along an axis (Z) of translation in the form of a function having, as a variable, the instantaneous angular position (y(t)) of a winding device (4). The load bars of the screens are sequentially moved into a plurality of positions in which the load bars are aligned, and then the angular position (y(t)) of the winding device is determined. Next, the coefficients defining the approximation function of each screen are determined. The movement of the load bar of each screen is controlled by an instantaneous angular-position set value (θ(t)), which is in turn predetermined from a representative profile using the one-to-one approximation function.

This electric actuator for driving a home-automation screen is provided with a spring brake (105) comprising a helical spring (130), a friction part (140) having a friction surface (141) against which the helical spring (130) bears radially. Said brake further comprises an inlet part (110) suitable for driving the spring in rotation in a direction reducing the contact force between the spring (130) and the friction part (140), and an outlet part (120) connected to the screen.While the screen is being lowered, the inlet part (110; 210) drives the spring (130; 230) in rotation with the contact force being decreased to the extent that the outlet part (120; 220) is released in rotation, without direct contact between the inlet part and the outlet part. The inlet part (110; 210) has at least two contact surfaces (113a, 113d; 213b, 217c) suitable for transmitting drive torque (CM) for raising the screen (2), by direct contact, to at least two corresponding contact surfaces (123a, 123d; 223b, 227a) of the outlet part (120; 220).

An automated control method for a solar protection screen (SCR) installation (INST) comprising retroreflecting-type slats (B1, B2, B3) which can be inclined between two extreme inclinations, wherein, in the presence of direct solar radiation, the slats are inclined at a first intermediate inclination, equal to the maximum aperture inclination (AMAX) of the screen relative to a preferred direction, as long as an inclination threshold automatically controlled in relation to the height of the sun (ATH) remains less than the maximum aperture inclination.
摘要:
Motorized device (2) for rolling up cords or tapes (13, 15) of Venetian or folded blinds, equipped with an automatic stopping device detecting a blockage of the motor. This automatic stopping device consists of a screw (6) carrying a traveling nut (7) rotationally retained in a tubular housing (9). Stoppage of the motor is caused by the detection of a blockage of the motor by the travelling nut (7) rotationally retained in a tubular housing (9). Stoppage of the motor is caused by the detection of a blockage of the motor by the travelling nut (7), or the blind, coming up against the casing. The bottom stopping point is adjusted by unblocking the cage (9) and rotationally driving it.
