Description

Electromechanical actuator, screening device and closing, screening or solar protection installation comprising such an electromechanical actuator or such a screening device

The present invention relates to an electromechanical actuator for a closing, screening or solar protection installation, in other words an electromechanical actuator for a closing, screening or solar protection installation, as well as a motorized drive device comprising such an actuator. The invention also relates to a closing, screening or solar protection installation comprising a screen driven in displacement by such an electromechanical actuator or which includes such a motorized drive device.

In general, the present invention relates to the field of concealment devices comprising a motorized drive device moving a screen between at least a first position and at least a second position.

A motorized drive device generally 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, called by the continued screen.

Electromechanical actuators are already known for closing, screening or solar protection installations which comprise a casing, a torque support, an electric power cable, an electric motor, an electronic control unit and a cover. The torque support is arranged at one end of the casing and cooperates with a holding device to take up the forces exerted by the electromechanical actuator. The power supply cable is configured to be connected to an electrical power supply network. The electric motor is mounted inside the housing and is supplied with electrical energy by means of the electrical supply cable. The electronic control unit comprises at least one electronic card arranged inside the torque support. The cover is mounted on a head of the torque support.

When installing such electromechanical actuators, it is common to have to adapt the torque support to a support of the holding device. Indeed, there is a wide variety of supports, which have different shapes with which the torque support must be compatible in order to be mounted.

For this, it is common to add an adapter to the torque support, making it possible to make the connection between the torque support and the support of the holding device, without having to adapt the shape of the torque support. Such an adapter is generally attached to one end of the torque support.

However, these adapters have the disadvantage of being inserted between the torque support and the support of the holding device, which creates an extra thickness at the end of the electromechanical actuator. This additional thickness leads to the creation of a space around the screen, between the screen and a side edge of an opening on which the closing, screening or solar protection installation is mounted, which generates light leaks . Thus, the occultation created by the screen is lower. Consequently, the addition of an adapter is unattractive and does not provide satisfactory screening.

The object of the present invention is to solve these drawbacks and to propose an electromechanical actuator, as well as a closing, screening or solar protection installation comprising such an electromechanical actuator, which can be easily adapted to the support of a holding device without degrading the concealment provided by a screen belonging to the installation.

Further, the torque bracket includes a mounting plate, the mounting plate being attached to one end of the torque bracket head by being mounted in a cutout in the side face of the cover. In addition, the mounting plate is provided with an opening configured to cooperate with a projecting part of a fixed support of a holding device to take up the forces exerted by the electromechanical actuator.

Thanks to the invention, the mounting plate is integrated into the electromechanical actuator so as not to protrude from the cover and not to create extra thickness at the end of the electromechanical actuator. Thus, the distance between the support of the holding device and the electromechanical actuator is minimal, which improves the concealment provided by the screen of an installation comprising such an electromechanical actuator.

Thus, the stop 33 of the torque support 21 makes it possible to limit the sinking of the first part 21a of the torque support 21 into the casing 17, in the direction of the axis of rotation X.

In addition, the stop 33 of the torque support 21 delimits the first and second parts 21a, 21b of the torque support 21 with respect to each other.

Thus, only the first part 21a of the torque support 21 is arranged inside the casing 17 of the electromechanical actuator 11, following the fitting of the torque support 21 inside the casing 17, until the stop 33, in particular in the assembled configuration of the electromechanical actuator 11, and the second part 21b of the torque support 21 extends outside the casing 17.

Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to rotate a connecting element, not shown, connected to the winding tube 4. The connecting element is made in the form of a wheel .

When the electromechanical actuator 11 is put into operation, the electric motor 16 and the reducer rotate the output shaft 20. In addition, the output shaft 20 of the electromechanical actuator 11 rotates the tube. winding 4 via the connecting element.

Thus, the winding tube 4 rotates the screen 2 of the screening device 3, so as to open or close the opening 1.

The electronic control unit 15 of the electromechanical actuator 11 comprises an obstacle and limit switch detection device, not shown, when rolling up the screen 2 and when rolling up this screen 2.

The device for detecting obstacles and limit switches during winding and during unwinding of the screen 2 is implemented by means of the microcontroller 30 of the electronic control unit 15 and, in particular, by means of of an algorithm implemented by this microcontroller 30.

Here, the electronic control unit 15, in particular the first and second electronic boards 15a, 15, are supplied with electrical energy by means of the electrical supply cable 18.

Advantageously, the electronic control unit 15 is arranged at least partly inside the casing 17 of the electromechanical actuator 11.

Furthermore, the electronic control unit 15 can be arranged at least partly outside the casing 17 of the electromechanical actuator 11 and, in particular, mounted in the torque support 21.

Here, the first electronic card 15a of the electronic control unit 15 is arranged inside the casing 17 of the electromechanical actuator 11, in particular in the assembled configuration of the electromechanical actuator 11. In addition, the second card electronic 15b is arranged inside the torque support 21 of the electromechanical actuator 11, in particular in the assembled configuration of the electromechanical actuator 11.

Here, the electronic control unit 15 has no box for receiving the first electronic card 15a. This first electronic card 15a is, on the one hand, maintained, in particular plugged, in the torque support 21, in particular in a third part 21c of the torque support 21, called the central part, as illustrated in , and, on the other hand, held, in particular plugged, in a support, not shown, mounted at the end of the electric motor 16, in particular in the assembled configuration of the electromechanical actuator 11.

Here, the second electronic card 15b is held, in particular plugged, in a central rib of the torque support 21, in particular in a central rib of the second part 21b of the torque support 21.

In particular, the second electronic card 15b is arranged inside a housing 44 formed in the second part 21b of the torque support 21, more precisely in a head 21e of the second part 21b. The housing 44 is delimited, along the X axis, on the one hand by a wall 21d of the torque support 21, visible in FIGS. 4 and 6 to 8 and which forms, along the X axis, one end of the head 21e of the second part 21b of the torque support 21, and on the other hand by a wall 21f of the torque support 21, visible in FIGS. 6 and 7, substantially parallel to the wall 21d and arranged along the axis X, between the wall 21d and the first internal part 21a of the torque support 21. In addition, the external surface of the head 21e of the second part 21b is of cylindrical shape.

Furthermore, the electronic card 15b comprises a connector 19, mounted on the printed circuit board 40b and which makes it possible to connect the connection cables connecting the first and second electronic cards.

Here and as shown in , the torque support 21 further comprises a cover 22. The cover 22 is mounted on the end of the second part 21b of the torque support 21, more precisely on the head 21e of the second part 21b, in particular in the assembled configuration of the electromechanical actuator 11. In addition, the cover 22 closes the housing 44 in the assembled configuration of the electromechanical actuator. In Figures 4 and 8, cover 22 is omitted for clarity.

The torque support 21 comprises at least one selection device 41, in particular a button, which can be, for example, of the push type.

This or these selection devices 41 are configured to, when they are activated, adjust the electromechanical actuator 11 through one or more configuration modes, pair with the electromechanical actuator 11 one or more control units 12, 13, reinitialize one or more parameters, which can be, for example, an end-of-travel position, reinitialize the paired control unit(s) 12, 13 or even control the movement of the screen 2.

Here, the torque support 21 comprises a single selection device 41.

The number of torque support selection devices is not limiting and may be different. It may, in particular, be greater than or equal to two.

The torque support 21 comprises at least one display device 42.

This or these display devices 42 are configured to display a visual indication, which may be, for example, representative of an operating mode of the electromechanical actuator 11, in particular a configuration mode or a control mode, or even a state of a member of the motorized drive device 5 or of the electrical power supply device 31, in particular a state of charge of the battery 24.

Advantageously, the display device 42 comprises at least one light source not shown, in particular a light-emitting diode, mounted on the second electronic card 15b.

Here, the torque support 21 comprises a single display device 42.

The number of display devices is not limiting and may be different. It may, in particular, be greater than or equal to two.

Advantageously, the selection device 41 and the display device 42 are electrically connected, in other words are configured to be electrically connected, to the electronic control unit 15.

Here, the selection device 41 and the display device 42 are electrically connected, in other words are configured to be electrically connected, to the second electronic control board 15b.

Advantageously, the selection device 41 and the display device 42 are mounted on the printed circuit board 40b.

As a variant, the selection device 41 and/or the display device 42 can be electrically connected, in other words can be configured to be electrically connected, to the first electronic control card 15a.

The torque support 21 may comprise either the selection device(s) 41 or the display device(s) 42, or the selection device(s) 41 and the display device(s) 42.

The housing 44 houses, in other words is configured to house at least the selection device(s) 41 or the display device(s) 42, in particular in the assembled configuration of the electromechanical actuator 11.

In this way, the housing 44 receives, in other words is configured to receive, at least one of the selection device(s) 41 and the display device(s) 42, in particular in the assembled configuration of the electromechanical actuator 11 .

Here, the torque support 21 comprises a single housing 44, where the selection device 41 and the display device 42 are housed.

Advantageously, the electromechanical actuator 11 further comprises a cover 70, partially inserting into the housing 44 and closing this housing 44, the cover surrounding the second electronic card 15b.

Here, the cover 70 includes a button 72, configured to actuate the selection device 41 under the effect of a press from a user.

Furthermore, the cover 70 includes a light guide 74, configured to guide light emitted by the display device 42 to the outside of the electromechanical actuator 11.

Here, the cover 70 is surrounded by the cover 22, so as to be covered by the cover. In particular, the cover covers and masks the lines of junction between the cover 70 and the walls 21d and 21f of the housing 44. Thus, in the assembled configuration of the electromechanical actuator 11, the cover 70 cannot be disassembled. When the cover 22 is removed, then the cover 70 can be removed from the housing 44, to make the second electronic card 15b accessible.

In other words, cover 22 protects second electronic card 15b and cover 70.

Advantageously, in a variant not shown, the cover 70 is configured to protect the second electronic card 15b from electrostatic discharges, by increasing a creeping path traversed by an electrostatic discharge, between the outside of the cover 70 and the second electronic card 15b, and possibly to protect the second electronic card 15b from splashing water and humidity. The cover then has a solid outer surface and the activation of the selection device 41 takes place by movement of the cover itself or by deformation of a flexible part of the cover in line with the detection device.

The absorption of the forces exerted by the electromechanical actuator on the structure of the building B, ensured by the torque support 21, is in practice obtained by preventing the rotation of the torque support 21, around an axis X21 of the torque support confused with the axis of rotation X in the assembled configuration of the actuator 11, relative to the buildingB.

This blocking of the rotation of the torque support 21, and therefore of the rotation of the fixed elements of the electromechanical actuator 11, such as the casing 17, is obtained by the cooperation of the torque support with the holding device 9, 23, in particular in an assembled configuration of the electromechanical actuator 11 in the concealment device 3.

In practice the torque support 21 comprises an opening 80, which extends into the torque support 21 from the wall 21d of the torque support, parallel to the axis X21.

Here, the opening 80 comprises a central part 80a and four arms 80b, arranged perpendicular to each other around the central part 80a. Thus, in the example, the opening 80 has the shape of a cross.

Alternatively, the aperture 80 has a different shape, such as a five-pointed star shape, a triangular shape, or another polygonal shape.

The opening 80 is configured to receive, in other words receives, part of the holding device 9, 23, and more particularly a projecting part of a fixed support 23.

In the case of the variant illustrated in , where the fixed supports 23 are not used and where the winding tube 4 is held by means of the flanges 10 of the box 9, the opening 80 is configured to receive a projecting part of a fixing bracket fixed to a flange 10 of the box 9. For simplicity, in the following description, such a fixing lug will be assimilated to a fixed support 23.

It is known that a wide variety of fixed supports 23 having various shapes can be used within the holding device 9, 23 to hold the winding tube 4.

To avoid having to adapt the shape of the opening 80 to the shape of the fixed support 23 of the installation 6, which would involve a wide variety of models of torque supports 21 that can be adapted to all shapes of fixed supports 23 , the torque support further comprises a mounting plate 90.

The mounting plate 90 of the torque support 21 is attached to the wall 21d of the torque support and is provided with an opening 92, which is aligned with the opening 80 of the torque support and whose shape is adapted to that of the part projecting from the fixed support 23, that is to say complementary to the shape of the fixed support 23.

To the , the trace of a fixed support 23 and of its projecting part 23a is shown in phantom, for illustrative purposes. Here, the fixed support 23 is in the form of a plate and its projecting part 23a extends perpendicular to the support, along an axis X23, with a cross-section in the shape of a cross with four branches 23b, each defined between two surfaces 23c. The projecting part 23a further comprises a circular central part 23d from which the branches 23b extend.

Here, the opening 92 of the mounting plate 90 comprises a central part 92a and four arms 92b, arranged perpendicular to each other around the central part 92a. Thus, in the example, the opening 92 has the shape of a cross.

In addition, each arm 92b has two bearing surfaces 92c.

By "bearing surface" is defined any surface of the opening 92 of the mounting plate 90 which generates a torque driving the torque support 21 in rotation when a force is exerted thereon, in other words any surface which transmits a force on a surface bearing against it in the event of rotation of the torque support, this force opposing the rotation of the torque support.

Thus, the opening 92 receives the projecting part 23a of the fixed support 23 and the bearing surfaces 92c of the opening 92 are in contact with the surfaces 23c of the projecting part 23a of the fixed support 23, at the operating clearance near, so that the rotation of the torque support 21 around the axis X21 is prevented in the mounted configuration of the electromechanical actuator 11 in the installation 6.

Thus, the opening 80 of the torque support 21 has a generic shape, provided to be able to receive various projecting parts of the fixed support 23 of different shapes, and the blocking of the rotation of the torque support 21 is ensured by the opening 92 of the mounting plate 90, which is specifically fitted to the protruding part 23a.

Moreover, the trace of the opening 92 of the mounting plate 90, projected in a plane perpendicular to the axis X21, is inscribed in the trace of the opening 80 of the torque support 21, projected in the same plane. In other words, several openings 92 are compatible with the opening 80 of the torque support, so that several plates 90 are compatible with the torque support 21 and thus make it possible to take up the forces exerted by the electromechanical actuator 11 by cooperation with the projecting part 23a of the fixed support 23.

It is advantageous to provide that the rotation of the torque support 21 is prevented by the opening of the mounting plate 90 rather than directly by the opening 80 of the torque support, because the mounting plate 90 is inexpensive and simpler to manufacture. It is thus easy to provide a wide variety of mounting plates 90, each adapted to a type of fixed support 23, more particularly to a geometry of projecting part 23a, thus making it possible to adapt a single torque support 21 to a large variety of fixed supports 23.

Another advantage of this system is to make it possible to use a different material for the mounting plate 90 and for the torque support 21. Indeed, the mounting plate being subjected to greater forces than the torque support, generated by the reaction of the fixed support 23 when the electromechanical actuator 11 is in operation, it is preferable that the material of the mounting plate 90 be very resistant, in particular harder than the material of the torque support 21.

Here, hardness is understood as the mechanical resistance that a material opposes to penetration.

Thus, the mounting plate is, for example, made of metallic material, for example stainless steel, which has good mechanical properties, that is to say which is resistant to wear, and the torque support is by example made of polymer material, preferably by molding, which makes it possible to produce a complex shape at a low cost price.

Advantageously, the mounting plate 90 is in one piece.

In practice, the mounting plate 90 is obtained by machining a solid plate, in which the mounting plate is cut, then in which the opening 92 is cut.

The mounting plate 90 then defines an outer surface S90 and an inner surface S'90, which are substantially flat, have no reliefs and are parallel to each other.

By "have no reliefs", it is meant that the mounting plate 90 does not include any protrusion extending from the faces S90 and S'90.

Alternatively, the mounting plate is made of rigid polymer material.

In addition, the mounting plate 90 is fixed to the torque support 21 using fixing elements, such as for example screws, represented in the figures by their axis lines 95.

In practice, the torque support 21 comprises holes 94 and the mounting plate 90 comprises holes 96, the holes 94 and 96 being adapted to receive the screws 95.

Advantageously, and more particularly when the fixing elements are screws with a conical head, the holes 96 of the mounting plate each comprise a countersink, configured to house the head of a conical screw, so that this head does not protrude mounting plate 90.

Here, the torque support 21 and the mounting plate 90 each include two holes 94, 96. Alternatively, the number of holes 94, 96 is different, for example three holes 94 and three holes 96.

Fixing and removing the mounting plate 90 from the torque support 21 is therefore particularly simple, since it is carried out using fixing elements that are simple and quick to implement. Thus, it is easy to change the mounting plate installed on the torque support 21, for example if, during the installation of the electromechanical actuator 11, the user notices that the mounting plate 90 is not suitable for fixed support 23.

As visible in Figures 5 to 7, the cover 22 is here cylindrical in shape, with a base 100 and a side face 102.

In the assembled configuration of the electromechanical actuator 11, the side face 102 is parallel to, and in contact with, the wall 21d of the torque support 21.

Here, the side face 102 comprises an opening 104 arranged opposite the selection device 41 when the cover 22 is mounted on the torque support 21, so that the selection device 41 is accessible and activatable through the opening 104 , from outside the electromechanical actuator 11.

In practice, the button 72 of the cover 70 extends through the opening 104 to allow the actuation of the selection device 41.

Similarly, the side face 102 comprises an opening 106 arranged opposite the display device 42 when the cover 22 is mounted on the torque support 21, so that a visual indication emitted by the display device 22 is visible. through the opening 106, from the outside of the electromechanical actuator 11.

In practice, the light guide 74 of the cover 70 extends through the opening 106 to transmit the visual indication emitted by the display device 22 through the cover 22.

Thus, the openings 104 and 106 make it possible to connect the second electronic card 15b to the outside of the electromechanical actuator 11, facing the electronic components carried by the second electronic card.

In practice, the number of openings 104, 106 of the cover 22 is adapted to the number of selection devices 41 and display devices 42 of the second electronic card 15b. For example, if the electronic card does not include a display device 42, then the cover 22 does not include an opening 106.

Side face 102 of cover 22 includes a cutout 110, in which mounting plate 90 is mounted.

Advantageously, the shape of the cutout 110 is complementary to the shape of the mounting plate 90. The cover 22 and the mounting plate 90 are therefore complementary to hide the head 21e of the torque support 21.

Thus, in the assembled configuration of the electromechanical actuator 11, the mounting plate 90 does not protrude from the cover 22 and the outer surface S90 of the mounting plate is flush with the side face 102.

By "flush" is meant that the distance between the outer surface S90 of the mounting plate 90 and the side face 102 of the cover 22, measured along the axis of rotation X, is less than 2 mm, preferably less than 1 mm.

The fact that the outer surface S90 of the mounting plate 90 is flush with the side face 102 of the cover 22 is particularly advantageous, since this makes it possible to minimize the distance between the fixed support 23 and the electromechanical actuator 11, which avoids light leaks around the screen 2, when the screen 2 is in the unrolled position, particularly when the installation 6 does not include side slides 26. The electromechanical actuator 11 is also more aesthetic.

Advantageously, the side face 102 of the cover 22 comprises a rim 112, in other words a rabbet, arranged around the cutout 110. In practice, the rim 112 is a projection which extends the side face 102 towards the cutout 110 on part of thickness of the side face 102.

In addition, the mounting plate 90 is advantageously provided with a shoulder 114, provided along an outer edge 90a of the mounting plate, the edge 90a being directed towards the wall 21d of the torque support 21.

In addition, the shoulder 114 and the rim 112 are of complementary shapes, so that in the assembled configuration of the electromechanical actuator 11, the shoulder rests on the rim and can exert thereon a force parallel to axis X21 and directed towards housing 17.

Thus, when the mounting plate 90 is fixed on the wall 21d of the torque support 21, the cover 22 is retained by the mounting plate by its edge, in contact against the shoulder.

The mounting plate 90 therefore also makes it possible to hold the cover 22 assembled on the torque support 21.

Alternatively, the flange 112 of the side face 102 is formed on only part of the cutout 110 and the shoulder 114 is formed on only part of the outer edge 90a of the mounting plate 90. For example, the flange 112 is formed on the cutout 110 in two portions, each portion having a length of between five and twenty millimeters, and the shoulder is formed on the edge 90a in two portions, each portion having a length of between five and twenty millimeters.

As a variant, the mounting plate 90 does not include a shoulder 114. The outer edge 90a then bears against the rim 112 of the cover 22, so as to hold the cover assembled on the torque support 21. Advantageously, in a such variant, the thickness of the mounting plate 90, measured along the axis X21, that is to say the distance between the surfaces S90 and S'90, is equal to or less than the thickness of the face side 102 of the cover 22, measured along the axis X21, so that the outer surface S90 of the mounting plate is flush with the side face 102. The rigidity of the mounting plate is thus maximized.

Here, the cover 22 also includes lugs 116, which are received in recesses 118 of the torque support 21, so that the cover 22 is snapped onto the torque support 21.

Thus, the cover 22 is mounted in two stages on the torque support 21: it is first snapped using the lugs 116, then fixed using the mounting plate 90.

In addition, the cover 22 is disassembled from the torque support in two stages: the mounting plate 90 is first removed, then the lugs 116 are moved away from the recesses 118, either using a tool, such as for example the tip of a flat screwdriver, or by elastic deformation of the cover.

This assembly and disassembly have the advantage of being particularly simple, which makes it possible to easily change the cover 22.

Thus, the cover 22 is easily changed, for example to modify its color or material, according to the preferences of a user of the installation 6.

As a variant, cover 22 is only held by snap-fastening onto torque support 21. Advantageously, in such a variant, mounting plate 90 does not include a shoulder 114 and cover 22 does not include a rim 112. In addition, in such a variant the cover 22 can be mounted and dismounted independently of the mounting plate 90, that is to say that the cover can be mounted and dismounted whether the mounting plate is mounted or dismounted. Likewise, mounting plate 90 can be assembled and disassembled independently of cover 22. Thus, cover 22 and mounting plate 90 are independently interchangeable.

In summary, the electromechanical actuator 11 is particularly advantageous, since it is simple to adapt to a fixed support 23, whatever the type of fixed support 23, and it is simple to customize, thanks to the mounting plate 90 and the cover 22, which are easily interchangeable.

In addition, the change of the mounting plate 90 and/or of the cover 22 is carried out without having to dismantle or modify the torque support 21 or disconnect the electrical connections located at the level of the torque support. This is particularly advantageous, because the torque support 21 is more complex and risky to disassemble, due to the presence of the electronic boards 15a and 15b which are fixed there and due to the connections, for example to the connector 19, which must be disconnected. in the event of disassembly of the torque support and which may be sensitive.

Moreover, when the mounting plate 90 is removed from the torque support 21, only a part of the wall 21 of the opening 80 is accessible from the outside of the electromechanical actuator 11. Thus, in this configuration, no element fragile of the electromechanical actuator, such as for example the electronic control unit 15 and in particular the second electronic card 15b and the connector 19, is not accessible. Changing the mounting plate 90 then presents no risk of damage to the electromechanical actuator. This advantage arises in particular from the fact that the dimensions of the mounting plate 90 are restricted with respect to the size of the torque support 21, the plate covering only part of the wall 21d of the torque support 21. The same advantage is present when cover 22 is removed, due to electronic card 15b being held in housing 44, closed by cover 70, and face 21d of the housing limiting access to electronic card 15b when cover 22 is took of.

Advantageously, the torque support 21 also includes fasteners 120, which extend from the wall 21d parallel to the axis X21.

In the example, the torque support 21 includes two fasteners 120.

The fasteners 120 form organs, independent of the mounting plate 90, to maintain the torque support 21 relative to the fixed support 23 and prevent the rotation of the torque support 21 around the axis X21. For example, the fasteners 120 are configured to receive two fixing pins belonging to the fixed support 23 and which extend parallel to the axis X23.

Thus, the torque support 21 offers two different mounting possibilities to the fixed support 23.

Advantageously, the mounting plate 90 also includes two notches 122, the shape of which is complementary to the shape of the fasteners 120. When the mounting plate 90 is fixed to the torque support 21, the fasteners 120 of the torque support are arranged in the recesses 122, so that the mounting plate 90 partially surrounds the clips and the clips 120 are flush with the outer surface S90 of the mounting plate, as best seen in . This makes it possible to leave the fasteners 120 free if necessary.

We now describe, and with reference to the inserts A) and B) of the , two variants of the mounting plate 90, and more specifically the differences between these two variants and the mounting plates 90 shown in Figures 3, 6, 7 and 8.

The opening 92 of the mounting plate 90 of the insert A) comprises four arms 92b arranged around the central part 92a, substantially of the same length, as does the mounting plate of FIGS. 6 and 7. With respect to the central part 92a of the mounting plate of Figures 6 and 7, the central part of the mounting plate of the insert A) is larger, that is to say that it can receive a projecting part 23a whose the circular central part 23d has a larger diameter, while the arms 92b are shorter.

The opening 92 of the mounting plate 90 of the insert B) comprises only two arms 92b arranged around the central part 92a and diametrically opposed. In addition, compared to the arms 92b of the insert A), the arms of the mounting plate of the insert B) are wider, that is to say that the distance separating the two bearing faces 92c of each arm, measured perpendicular to these support surfaces, is greater. Thus, the opening 92 can receive a projecting part 23a whose branches 23b are thicker. Similarly, the lengths of the arms 92b are greater than the lengths of the arms of the insert A)

Many modifications can be made to the embodiments described above, without departing from the scope of the invention.

As a variant, the projecting part 23a of the support has a different geometry, for example with a star-shaped cross section, a section with two or three branches or a polygonal section. In this case the geometry of the opening 92 is adapted. The opening 92 then comprises a different number of arms 92b, for example two arms or three arms, or a different shape, such as for example a triangular shape. The opening of the mounting plate 92 must in all cases remain compatible with the opening 80 of the torque support, in other words, the shape of the opening 92 fits into the shape of the opening 80 of the torque support. couple.

Whatever the shape of the opening 92, the opening has at least one bearing surface 92c.

Alternatively, not shown, the opening 110 of the cover 22 is substantially equal to the perimeter of the mounting plate 90, so that the mounting plate fits into the opening of the cover 22 without the torque support 21 is visible between the cover and the mounting plate. In this variant, the mounting plate 90 does not include a shoulder and the cover opening does not include a rim. The plate is simply mounted in the lid opening and both can be removed separately.

Alternatively, not shown, the electromechanical actuator 11 is inserted into a rail, in particular of square or rectangular section, which can be opened at one or both ends, in particular in the assembled configuration of the concealment device 3 Furthermore, the electromechanical actuator 11 can be configured to drive a drive shaft on which the cords for moving and/or orienting the screen 2 are wound.

Furthermore, the embodiments and variants envisaged can be combined to generate new embodiments of the invention, without departing from the scope of the invention.
