Definitions

the present invention relates to a motor drive device for a screening device, in other words a motor drive device for a screening device.
the present invention also relates to a screening device, in particular a closure device, comprising a screen that can be rolled up around a tube by means of the motorized drive device.
the present invention relates to the field of screening devices comprising a motorized drive device that sets a screen in motion between at least a first position and at least a second position.
a motorized drive device comprises an electromechanical actuator for a movable closing, shading or solar protection element such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter called a screen. .
the motor drive device includes a tube, a mounting bracket, a first jaw, a second jaw, and an electromechanical actuator.
the tube is configured to be fixed relative to a frame.
the mounting bracket is fixed to the tube by means of the first and second jaws.
Each of the first and second jaws is held relative to the mounting bracket by means of a hinge, respectively along a first side of the tube and along a second side of the tube.
the second side of the tube is opposed to the first side of the tube with respect to a longitudinal axis of the tube.
the electromechanical actuator is fixed on the mounting bracket. This motorized drive device is generally satisfactory.
this motorized drive device has the drawback of keeping the tube bearing against the mounting support by means of the first and second jaws, that is to say by means of two additional sub-assemblies with respect to the support. disassembly.
the motorized drive device is complex to industrialize, since it requires a large number of parts for the tube to be held in position against the mounting support by means of the first and second jaws articulated with respect to the mounting support. .
the holding in position of the first and second jaws between them is achieved by clamping elements, so as to guarantee a clamping force against the tube by means of the mounting support and the first and second jaws.
the mounting support and the first and second jaws are made from metal parts in the form of cut, bent and/or stamped sheets.
the mounting support and the first and second jaws are brought into contact with the tube via the edges of the metal parts in the form of sheets constituting the mounting support and the first and second jaws.

the clamping force of the mounting support and the first and second jaws on the tube is carried out on areas of small dimensions corresponding to the thickness of the sheets forming the mounting support and the first and second jaws.
the distribution of the clamping force of the assembly support and of the first and second jaws on the tube is limited to these areas of small dimensions and can cause local deformation and, more particularly, shearing of the tube at the level of the contact zones, on the one hand, between the mounting support and the tube and, on the other hand, between the first and second jaws and the tube.
Such a shearing effect of the tube 4 by the mounting support and/or the first and second jaws can be accentuated in the case where the edges of the metal parts in the form of sheets, which constitute the mounting support and the first and second jaws , have burrs.
the object of the present invention is to resolve the aforementioned drawbacks and to propose a motorized drive device for a screening device, as well as a screening device comprising such a motorized drive device, making it possible to simplify assembly of the motor-drive device and to avoid deformation of the tube of the motor-drive device when fixing the latter against the mounting bracket by means of clamping elements, while minimizing the costs of obtaining the motor drive device.

such a construction of the motorized drive device allows the mounting bracket to be fixed to the tube by means of a single flange. This simplifies assembly of the motor drive device and avoids deformation of the tube when fixing the latter against the mounting bracket and the single flange by means of the clamping elements, while minimizing the costs of obtaining the device motor drive.
a clamping force is exerted directly on the tube by the single flange, in particular an internal surface of the single flange, and by the mounting support, in particular an internal surface of the mounting support, by means of on the one hand, of the articulation between the single flange and the mounting support of the first side of the tube and, on the other hand, of the clamping elements connecting the single flange to the mounting support of the second side of the tube.

the tube comprises at least one hole.
the single bridle includes at least one pawn.
the pin of the single flange is inserted into the hole of the tube, so as to position the single flange and the mounting bracket relative to the tube, in rotation around the longitudinal axis of the tube and in translation along the longitudinal axis of the tube.
the clamping elements comprise at least one screw and at least one nut.
the nut is arranged in a receptacle of the mounting support, so as to be captive.
the single flange comprises at least one opening.
the mounting bracket includes at least one mounting hole. Further, the single flange opening and the mounting bracket fixing hole cooperate with the clamping elements.
At least one concave zone of an internal surface of the single flange has a radius of curvature equivalent to an external radius of the tube.
at least one concave area of an inner surface of a housing of the mounting bracket has a radius of curvature equivalent to the outer radius of the tube.
the mounting support comprises first gadroons, extending along the longitudinal axis of the tube.
