A screen (1) includes a load bar (2), a flexible element (3) supporting the load bar, and a controlled member (4) for winding the flexible member, wherein the member is controlled according to a method that includes controlling the angular movement of the winding member (4) with a temporal set value (θ(t)) of the instantaneous angular position of the winding member, the temporal set value being predetermined from a profile representative of the desired instantaneous axial position for the load bar upon a movement between the first and second positions, using a polynomial function of a degree higher than or equal to 2, which approximates the relation between a value of the instantaneous axial position (H(t)) of the load bar and an instantaneous angular position (γ(t)) of the winding member (4).

This driving carriage for a sliding curtain comprises a body that can move along a rail by virtue of two pairs of carrier wheels supported by the carriage, this body being provided, between the two pairs of carrier wheels along the longitudinal axis of the carriage, with at least one opening designed to receive a part of an inner curved edge of the rail without the rail striking the carriage. This eliminates or greatly limits the risks of the carriage becoming jammed along the rail.

The control interface (3) can be used to control a system (1) comprising home automation appliances (2a to 2e). It comprises input keys (8, 9) and an information screen (4) and it is noteworthy in that the screen comprises a main area (5) subdivided into cells (6a, 6b), in each of which a symbol can be displayed, the cells being able to be associated with appliances or with groups of appliances and/or associated with appliance control commands. The invention also relates to methods of operating this interface.

The method describes the operation of a roller blind including a moving element that can be operated via an actuator and a handheld-type remote control used to set the value of an operating parameter of the system, the value of this parameter being modifiable between two limit values. In this method, after a modification of the setting of the parameter value, an acknowledgement signal is sent, the acknowledgement signals differing according to whether the parameter value is or is not a limit value.

The device has a winding drum (5) mounted fixedly in terms of translation in a frame (1) and to insure that the cord is wound in even turns without overlapping there is of a traveling nut (6) engaging with a screw thread formed on the winding drum and an eyelet for guiding (8) the cord at its entry into the frame (1). The nut moves between an end of the cord (7a) fixed to the drum and the guiding eyelet (8). In the traveling nut is furthermore advantageously mounted a retractable stop (13) controlled by the cord (7) in order to oppose the rotation of the drum in the direction of unwinding when the cord is slack.

The invention relates to a coupling device (200) to be installed between an output shaft and an input shaft, such as an output shaft of an electric motor and an input shaft of a reducing gear of an actuator for driving a screen or a hatch that is part of home-automation equipment for closure, solar protection, or projection. Said coupling device (200) includes a first member (201) which is rotatably secured, or suitable for being rotatably secured, to the output shaft, and which is provided with at least one longitudinal outer groove (2013), and a second member (202) which is rotatably secured, or suitable for being rotatably secured, to the input shaft, and which is provided with at least one longitudinal outer groove (2023). Said coupling device (200) further includes an element (203) for rotatably coupling the first and second members together, which has, on at least one surface (2031) thereof, at least two series (S1, S2) of lugs (204) projecting from said surface, wherein the lugs (204) are inserted into the longitudinal outer groove (2013) of the first member (201) and the longitudinal outer groove (2023) of the second member (202), respectively.
摘要:
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.

This spring-loaded brake (105) for an actuator for driving a household screen comprises a helical spring (30) each end of which forms a lug (32a, 32b) extending radially, a friction piece (40) comprising a friction surface (41) against which the helical spring (30) presses radially, an input piece (10) able to drive the rotation of the spring (30) about a central axis (X30) in one direction reducing the force of contact between the helical spring (30) and the friction surface, and an output piece (20) able to drive the rotation of the spring (30) about its axis in a direction increasing the force of contact between the helical spring and the friction surface. This brake (105) additionally comprises two pieces (10, 50) which always rotate as one about the axis (X30) of the spring and each of which forms an end stop (16, 57) to an axial movement of the helical spring (30). The end stop (16) formed by one of these pieces (10) is able to limit the axial movement of the spring in a first direction, whereas the end stop (57) formed by the other piece (50) is able to limit the axial movement of the spring in a second direction opposite to the first direction.
摘要:
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).
