Description

Title of the invention: Concealment device comprising a motorized drive device

[0001] The present invention relates to a concealment device.

[0002] Generally speaking, the present invention relates to the field of occultation devices comprising a motorized drive device setting a screen in motion, between at least a first configuration and at least a second configuration.

[0003] A motorized drive device comprises an electromechanical actuator of a movable closing, concealing or sun protection element, such as a blind or any other equivalent material, hereinafter called a screen.

[0004] Document FR-A-3 111 939 is already known, which describes a screening device comprising a screen, a screen holding device, a load bar, a motorized drive device and an electrical power supply device. A first end of the screen is fixed to the screen holding device. A second end of the screen is fixed to the load bar. The motorized drive device comprises an electromechanical actuator configured to move the screen. The electrical power supply device comprises a battery, a first electrical connection element secured to the load bar or the screen and a second electrical connection element secured to the holding device. The battery is secured to the screen holding device. The battery is electrically connected to the electromechanical actuator and to the second electrical connection element.The first electrical connection element is configured to be electrically connected to an external electrical power supply source. The first electrical connection element is configured to cooperate with the second electrical connection element, so as to establish an electrical connection between the first electrical connection element and the second electrical connection element, only when the screen is in a retracted configuration corresponding to a battery recharging configuration, in order to electrically connect the external electrical power supply source to the battery, to recharge the battery. The electrical power supply device comprises an elastic element fixed on the charging bar or on the screen. The first electrical connection element is integral with the elastic element.The elastic element comprises a spring and makes it possible to compensate for a misalignment of the first electrical connection element relative to the second electrical connection element, when the screen reaches the retracted configuration. When the screen . is in the retracted configuration, the first electrical connection element and the second electrical connection element are thus aligned along an axis of movement of the screen. This concealment device is generally satisfactory.

[0005] However, this concealment device has the disadvantage that the elastic element is fragile and can break after a significant number of usage cycles, thus preventing the battery from being recharged. In addition, the elastic element is not very aesthetic, because it is particularly visible to a user of the device.

[0006] The present invention aims to resolve the aforementioned drawbacks and to propose a concealment device making it possible to easily connect a first electrical connection element to a second electrical connection element, when the screen reaches a retracted configuration, while being robust and aesthetic.

[0007] To this end, the invention relates to a screening device comprising: - a screen, - a holding device, for supporting the screen, a first end of the screen being attached to the holding device, - a load bar, a second end of the screen being fixed to the load bar, - an electromechanical actuator, configured to drive the screen along an axis of movement between a retracted configuration of the screen and a deployed configuration of the screen, the load bar then being moved relative to the holding device, - an electrical power supply device, comprising at least: • a main battery, the main battery being integral with the holding device, the main battery being electrically connected to the electromechanical actuator and configured to electrically power the electromechanical actuator in order to drive the screen between its retracted configuration and its deployed configuration, • a first electrical connection element, the first electrical connection element being secured to the load bar, the first electrical connection element being configured to be electrically connected to an electrical power supply source, • a second electrical connection element, the second electrical connection element being integral with the holding device, the second electrical connection element being electrically connected to the main battery,

[0008] According to the invention, the occultation device further comprises a device attachment secured to the holding device. The attachment device is configured to exert a force on the load bar when the screen approaches the retracted configuration, the force being oriented in a attachment direction having at least one component along an axis perpendicular to the axis of movement, the force tending to bring the load bar closer to the holding device in the attachment direction towards a connection position of the load bar. The attachment device is configured to ensure mechanical contact between the load bar and the holding device in order to establish an electrical connection between the first electrical connection element and the second electrical connection element when the screen is in the retracted configuration and the load bar in the connection position.

[0009] Thus, when the screen reaches or approaches its retracted configuration, the force exerted by the attachment device makes it possible to move the load bar so as to bring the first electrical connection element into contact with the second electrical connection element, thus ensuring electrical contact between these electrical connection elements.

[0010] In this way, it is advantageously not necessary to use an elastic element or a very precise adjustment system to compensate for a misalignment of the first electrical connection element relative to the second electrical connection element, when the screen reaches its retracted configuration, which improves the robustness and aesthetics of the occulting device.

[0011] According to other advantageous aspects of the invention, the occultation device comprises one or more of the following characteristics, taken individually or in all technically possible combinations:

[0012] - The force exerted by the hooking device tends to bring one end of the load bar of the holding device in the hooking direction.

[0013] - The first electrical connection element and the second connection element electrical are opposite each other along the axis of movement when the screen is in the retracted configuration.

[0014] - The second electrical connection element comprises electrical contacts extending parallel to the hooking direction, which are spring pins comprising a retractable pin subjected to the action of a spring or are in the form of metal plates. The first electrical connection element comprises electrical contacts which are in the form of metal plates, or respectively are spring pins comprising a retractable pin subjected to the action of a spring.

[0015] - The hooking device comprises a magnet and the force exerted by the device The grip on the charging bar when the screen is in the retracted configuration corresponds to an attractive force exerted by the magnet on the electrical contacts in the form of metal plates.

[0016] - The magnet of the hooking device is arranged between two electrical contacts under spring pin shape of the first electrical connection element or the second electrical connection element.

[0017] - The hanging device comprises a bracket and a slide extending parallel in accordance with the hooking direction, the bracket being fixed to the holding device by means of the slide, the second electrical connection element and the magnet being carried by the bracket.

[0018] - The direction of attachment is perpendicular to the axis of movement and the direction of attachment is perpendicular to an axis of rotation of the electromechanical actuator.

[0019] - The hanging device comprises a bearing surface extending in a plane parallel to an axis of rotation of the electromechanical actuator and oblique to the axis of movement, the approach direction being perpendicular to the plane of the support surface, the support surface being fixed relative to the holding device, the support surface being configured to generate the force when the electromechanical actuator moves the screen from its deployed configuration to its retracted configuration and when the load bar is in contact with the support surface.

[0020] - The first electrical connection element is arranged at one end of the bar charging and the hooking device comprises a housing, in which the second electrical connection element is arranged and towards which the bearing surface guides the end of the charging bar when the electromechanical actuator moves the screen from its deployed configuration to its retracted configuration.

[0021] - The first electrical connection element comprises metal tracks arranged along the support surface and the second electrical connection element is arranged on an outer face of the load bar opposite the support surface.

[0022] - The electrical energy supply device further comprises a battery secondary, secured to the charging bar and electrically connected to the first electrical connection element, and a photovoltaic solar panel, secured to the charging bar and electrically connected to the secondary battery, the photovoltaic solar panel being a source of electrical energy supply for the first electrical connection element.

[0023] - The electrical power supply device further comprises a connector charging, the charging connector being secured to the charging bar, the charging connector being electrically connected to the first electrical connection element and being configured to be electrically connected to an external power supply source.

[0024] The invention will appear more clearly on reading the description which follows, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0030] [Fig.6] [Fig.6] is a schematic perspective view of part of the installation illustrated in Figures 1, 2, 4 and 5.

[0031] [Fig.7] [Fig.7] is a schematic perspective view similar to that of [Fig.6], with certain elements of the installation in [Fig.6] hidden.

[0032] [Fig.8] [Fig.8] groups together two inserts showing, in side view, an installation comprising a concealment device in two configurations, the concealment device being in accordance with a second embodiment of the invention.

[0033] First of all, with reference to Figures 1 and 2, an installation 6 is described, comprising a closing, concealing or solar protection device 3 according to a first embodiment of the invention, installed in a building B comprising an opening 1, window or door. This installation 6 is equipped with a screen 2 belonging to the closing, concealing or solar protection device 3, in particular a motorized blind.

[0034] The closing, concealing or sun protection device 3 is hereinafter called the “concealing device”. The concealing device 3 comprises the screen 2.

[0035] The blackout device 3 may comprise a blind, in particular a canvas, a roller blind, a pleated blind or a slatted blind. The present invention applies to all types of blackout device.

[0036] The occulting device 3 comprises a winding tube 4 and a motorized drive device 5. The motorized drive device 5 comprises an electromechanical actuator 11 illustrated in [Fig.3].

[0037] The screen 2 of the occulting device 3 is wound on the winding tube 4 driven by the motorized drive device 5. Thus, the screen 2 is movable between a wound position, in particular high, also called wound configuration or retracted configuration or high configuration, and an unrolled position, in particular low, also called unrolled configuration or low configuration.

[0038] The screen 2 extends along a displacement axis Z when it is unrolled. The Z axis is also the displacement axis Z of the screen under the effect of the motorized drive device 5. The displacement axis Z is vertical in the example.

[0039] The screen 2 of the occultation device 3 is a closing, occultation and / or solar protection screen, winding and unwinding around the winding tube 4, the internal diameter of which is greater than the external diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, during the assembly of the occultation device 3.

[0040] Advantageously, the concealment device 3 comprises a holding device 9, 23.

[0041] Advantageously, the holding device 9, 23 may comprise two supports 23. A support 23 is arranged at each end of the winding tube 4, in an assembled configuration of the concealing device 3.

[0042] Thus, the winding tube 4 is held by means of the supports 23. Only one of the supports 23 is visible in Figures 1 and 5. The supports 23 make it possible to mechanically connect the concealment device 3 to the structure of the building B, in particular to the wall M of the building B.

[0043] Advantageously, the holding device 9, 23 may comprise a box 9. Furthermore, the winding tube 4 and at least part of the screen 2 are housed inside the box 9, in the assembled configuration of the occulting device 3.

[0044] Generally, the box 9 is arranged above the opening 1, or in the upper part of the opening 1.

[0045] Here and as illustrated in [Fig. 1], the supports 23 are also housed inside the box 9.

[0046] Advantageously, the box 9 comprises two cheeks 10, as illustrated in [Fig. 2]. A cheek 10 is arranged at each end of the box 9, in the assembled configuration of the concealing device 3.

[0047] As a variant, shown in [Fig. 2], the winding tube 4 is held by means of the box 9, in particular by means of the cheeks 10 of the box 9, without using supports, such as the supports 23 mentioned above.

[0048] The electromechanical actuator 11 is, for example, of the tubular type. This makes it possible to rotate the winding tube 4 around an axis of rotation X, so as to unwind or wind the screen 2 of the occulting device 3.

[0049] Thus, the screen 2 can be wound and unwound on the winding tube 4. In the mounted state, the electromechanical actuator 11 is inserted into the winding tube 4.

[0050] The concealment device 3 further comprises a weighted load bar 8 for exert tension on the screen 2. The tension generated by the load bar 8 on the screen 2 is directed along the movement axis Z.

[0051] Advantageously, the load bar 8 comprises a first end 8a and a second end 8b. The second end 8b is opposite the first end 8a.

[0052] As visible in [Fig.2], the ends 8a, 8b of the load bar are engaged, in other words are configured to be engaged, in the grooves 29 of the lateral slides 26, so that the movement of the load bar 8 is guided by the lateral slides 26.

[0053] The roller blind, which forms the occultation device 3, comprises a fabric, forming the screen 2 of the roller blind 3. A first end 2b of the screen 2, in particular the upper end of the screen 2, called the high end, in the assembled configuration of the occultation device 3, is fixed to the winding tube 4, in other words is attached to the holding device 9, 23. In addition, a second end 2c of the screen 2, in particular the lower end of the screen 2, called the low end, in the assembled configuration of the occultation device 3, is fixed to the load bar 8. The load bar 8 is thus suspended under the screen 2 at its second end 2c.

[0054] Here, the canvas forming the screen 2 is made from a textile material.

[0055] In an exemplary embodiment, not shown, the first end 2b of the screen 2 has a hem through which a rod, in particular made of plastic material, is arranged. This hem produced at the first end 2b of the screen 2 is obtained by means of a seam of the fabric forming the screen 2. When assembling the screen 2 on the winding tube 4, the hem and the rod located at the first end 2b of the screen 2 are inserted by sliding into a groove provided on the external face of the winding tube 4, in particular over the entire length of the winding tube 4, so as to secure the screen 2 with the winding tube 4 and to be able to wind and unwind the screen 2 around the winding tube 4.

[0056] Whatever the embodiment, the first end 2b of the screen 2 is arranged at the level of the holding device 9, 23, in the sense that this first end 2b remains above the opening 1 in the assembled configuration of the concealing device 3.

[0057] In the case of a roller blind, the high position, or rolled-up position, or retracted configuration, corresponds to a predetermined high end-of-travel position, or to the loading bar 8 of the screen 2 resting against an edge of a box 9 of the roller blind 3, or to a configuration where the loading bar 8 is close to the holding device 9, 23. It may, in particular, be considered that the loading bar 8 is close to the holding device 9, 23 when the load bar 8 is located above the opening 1.

[0058] In the case of a roller blind, the low position, or unrolled position, or deployed configuration, corresponds to a predetermined low end-of-travel position, or to the loading bar 8 of the screen 2 resting against a threshold 7 of the opening 1, or to the complete unrolling of the screen 2, or to a configuration where the loading bar 8 is further from the holding device 9, 23 than in the retracted configuration. In other words, when the screen 2 is not in the retracted configuration, it is in the deployed configuration.

[0059] Advantageously, the motorized drive device 5 is controlled by a control unit. The control unit may be, for example, a local control unit 12 or a central control unit 13.

[0060] Advantageously, the local control unit 12 can be connected, by wired or wireless connection, with the central control unit 13.

This electronic control unit 15 is capable of putting the electric motor 16 of the electromechanical actuator 11 into operation, and, in particular, of allowing the electric motor 16 to be supplied with electrical energy.

The display elements may comprise light-emitting diodes and / or an LCD (acronym for the English term “Liquid Crystal Display”) or TFT (acronym for the English term “Thin Film Transistor”) display. The selection and display elements may also be implemented using a touch screen.

[0077] The local control unit 12 and / or central control unit 13 comprises at least a second communication module 36.

[0078] Thus, the second communication module 36 of the local control unit 12 or central control unit 13 is configured to transmit, in other words emit, control orders, in particular by wireless means, for example radioelectric, or by wired means.

[0079] Furthermore, the second communication module 36 of the local control unit 12 or central control unit 13 can also be configured to receive, in other words receives, control orders, in particular via the same means.

[0080] The second communication module 36 of the local control unit 12 or central control unit 13 is configured to communicate, in other words communicates, with the first communication module 27 of the electronic control unit 15.

[0081] Thus, the second communication module 36 of the local control unit 12 or central control unit 13 exchanges control orders with the first communication module 27 of the electronic control unit 15, either in a unidirectional manner or in a bidirectional manner.

[0082] Advantageously, the local control unit 12 is a control point, which may be fixed or mobile.

These control orders can be issued, in particular, by the local control unit 12 or by the central control unit 13.

[0085] The motorized drive device 5 can be controlled by the user, for example by receiving a control command corresponding to pressing the or one of the selection elements 14 of the local control unit 12 or central control unit 13.

[0120] Advantageously, at least a portion of the first part 21a of the torque support 21 is of generally cylindrical shape and is arranged inside the casing 17 of the electromechanical actuator 11, in the assembled configuration of the electromechanical actuator 11.

[0121] Advantageously, an outer diameter 0212 of at least a portion of the second part 21b of the torque support 21 is greater than an outer diameter 017 of the casing 17 of the electromechanical actuator 11.

[0122] Advantageously, the torque support 21 comprises a stop 33 configured to cooperate, in other words which cooperates, with the casing 17, at the level of the first end 17a of the casing 17, in the assembled configuration of the electromechanical actuator 11.

[0123] 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 in the casing 17, in the direction of the axis of rotation X.

[0124] Furthermore, the stop 33 of the torque support 21 delimits the first and second parts 21a, 21b of the torque support 21 relative to each other.

[0125] 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, up to the stop 33, in the assembled configuration of the electromechanical actuator 11.

[0126] Here, the stop 33 of the torque support 21 is produced in the form of a shoulder and, more particularly, in the form of a collar, in particular of cylindrical shape and with a rectilinear generatrix.

[0127] Advantageously, the electronic control unit 15 can be arranged at least partly inside the casing 17 of the electromechanical actuator 11.

[0128] Furthermore, the electronic control unit 15 may be arranged at least partly outside the casing 17 of the electromechanical actuator 11 and, in particular, mounted on one of the two supports 23, on one of the cheeks 10 of the box 9 or in the torque support 21.

[0129] Here, the first electronic card 15a of the electronic control unit 15 is arranged inside the casing 17 of the electromechanical actuator 11. Furthermore, the second electronic card 15b is arranged inside the torque support 21 of the electromechanical actuator 11.

[0130] Here and as illustrated in [Fig.3], the torque support 21 comprises a cover 22. Furthermore, the second electronic card 15b is arranged inside a housing formed between the second part 21b of the torque support 21 and the cover 22.

[0131] Advantageously, the torque support 21 comprises at least one button, not shown.

[0132] This or these buttons can make it possible to adjust the electromechanical actuator 11 through one or more configuration modes, to pair one or more control units 12, 13 with the electromechanical actuator 11, to reset one or more parameters, which may be, for example, an end-of-travel position, to reset the paired control unit(s) 12, 13 or even to control the movement of the screen 2.

[0133] Here, the torque support 21 comprises a single button.

[0134] The number of buttons of the torque support is not limiting and may be different. It may be, in particular, greater than or equal to two.

[0135] Advantageously, the torque support 21 comprises at least one display device, not shown, so as to allow a visual indication, which may be, for example, a state of charge of the main battery 24.

[0136] Advantageously, the display device comprises at least one lighting source, not shown, in particular a light-emitting diode, mounted on the second electronic card 15b and, optionally, a transparent or translucent cover and / or a light guide, to allow the passage of the light emitted by the lighting source.

[0137] Here, the torque support 21 comprises a single display device.

[0138] The number of display devices is not limiting and may be different. It may be, in particular, greater than or equal to two.

[0139] Advantageously, the output shaft 20 of the electromechanical actuator 11 is arranged inside the winding tube 4 and at least partly outside the casing 17 of the electromechanical actuator 11.

[0140] Here, one end of the output shaft 20 projects relative to the casing 17 of the electromechanical actuator 11, in particular relative to a second end 17b of the casing 17 opposite the first end 17a.

[0141] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive in rotation a connecting element, not shown, connected to the winding tube 4. The connecting element is produced in the form of a wheel.

[0142] When the electromechanical actuator 11 is put into operation, the electric motor 16 and the reducer 19 drive the output shaft 20 in rotation. In addition, the output shaft 20 of the electromechanical actuator 11 drives the winding tube 4 in rotation via the connecting element.

[0143] Thus, the winding tube 4 rotates the screen 2 of the occulting device 3, so as to open or close the opening 1.

[0144] The electrical energy supply device 31 will now be described with reference to FIGS. 4 to 7.

[0145] Advantageously, the electrical energy supply device 31 comprises a charging connector 40, arranged at the level of the charging bar 8. The charging connector 40 is for example a connector according to the USB standard, from the English “Universal Serial Bus”, preferably a USB Type-C connector.

[0146] The charging connector 40 is configured to be electrically connected, in other words is electrically connected, to an external power supply source 42 configured to provide the electrical power supply device 31 with electrical energy.

[0147] Advantageously, the external electrical power supply source 42 is a charger-converter that can be plugged into a wall electrical outlet, so as to provide a direct current power supply to the electrical power supply device 31 from an alternating current mains power supply network.

[0148] Advantageously, the external electrical power supply source 42 is connected to the charging connector 40 using a corresponding connector (not shown) at the end of an electrical power supply cable 43.

[0149] The electrical power supply device 31 further comprises a first electrical connection element 44 visible in FIGS. 4 and 5 and a second electrical connection element 46 visible in FIGS. 4 to 7.

[0150] The first electrical connection element 44 is arranged at the level of the load bar 8 of the concealment device 3. By “at the level of the load bar”, it is meant that the first electrical connection element 44 is integral with the load bar 8. In the example, the first electrical connection element 44 is integrated into the second end 8b of the load bar 8.

[0151] The first electrical connection element 44 is electrically connected to the charging connector 40. Thus, the first electrical connection element 44 is configured to be electrically connected, in other words is electrically connected, to the external electrical power supply source 42 via the charging connector 40, when the external electrical power supply source 42 is connected to the charging connector 40.

[0152] The second electrical connection element 46 is arranged at the level of the holding device 9, 23 of the screen 2. By “at the level of the holding device”, it is meant that the second electrical connection element 46 is integral with the holding device 9, 23, in particular with the box 9, with one of the cheeks 10 or with one of the supports 23, or with the torque support 21. In the example, the second electrical connection element 46 is fixed to one of the two supports 23 by means of a fixing lug 23a.

[0153] The second electrical connection element 46 is electrically connected to the main battery 24. In the example, the electrical power supply device 31 comprises a partially shown electrical cable 47, which is electrically connected on the one hand to the second electrical connection element 46 and on the other hand to the main battery 24. For example, the electrical cable 47 extends from the second electrical connection element 46 to the main battery 24 via a fixing lug 23a, then the torque support 21, at the first end 17a of the casing 17. The electrical cable 47 may comprise one or more cable portions and one or more electrical connectors, for example an electrical connector integrated into the torque support.

[0154] The second electrical connection element 46 is configured to cooperate, in other words cooperates, with the first electrical connection element 44 so as to establish an electrical connection between the first electrical connection element 44 and the second electrical connection element 46, consequently between the source external electrical power supply 42 and the main battery 24. This cooperation can only take place when the screen 2 is placed in the retracted configuration and the first and second electrical connection elements are opposite each other. A connection position of the charging bar 8 is defined as a position in which an electrical connection is established between the first electrical connection element 44 and the second electrical connection element 46.

[0155] Thus, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is implemented only when the first electrical connection element 44 is arranged in proximity to the second electrical connection element 46 or, preferably, against, i.e. in contact with, the second electrical connection element 46, so as to be able to recharge the main battery 24 from the external electrical power supply source 42.

[0156] In this way, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is implemented without an electrical power cable connecting the first electrical connection element 44 to the second electrical connection element 46, so as to guarantee the reliability of this electrical connection and to minimize the costs of obtaining the occultation device 3.

[0157] In the example, when the screen 2 is in the retracted configuration and the charging bar 8 is in the connection position, the first electrical connection element 44 and the second electrical connection element 46 are aligned, that is to say are opposite each other, along an axis Y perpendicular to the axis of movement Z and perpendicular to the axis of rotation X.

[0158] Preferably, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is made using electrical contacts. In a variant of the invention not shown, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is made by induction.

[0159] In the example, this electrical connection is made using electrical contacts. For this purpose, the second electrical connection element 46 comprises four electrical contacts 48, which are Pogo type pins, or spring pins, that is to say pins composed of a pin sliding in a cylinder, the pin being constrained relative to the cylinder by an internal spring. In other words, each electrical contact 48 comprises a retractable pin subjected to the action of a spring.

[0160] In practice, the four electrical contacts 48 are grouped into two groups of two electrical contacts, the two electrical contacts of the same group being electrically connected to each other. In other words, the electrical contacts 48 are duplicated, that is to say redundant, allowing the second electrical connection element 46 to operate normally in the event of failure of an electrical contact 48.

[0161] In a non-shown variant of the invention, the second electrical connection element 46 does not comprise two groups of two electrical contacts 48, but comprises two electrical contacts 48.

[0162] In a variant of the invention not shown, each contact group comprises a number of electrical contacts 48 other than two, for example three or four.

[0163] In a non-shown variant of the invention, the second electrical connection element 46 comprises electrical contacts of a type other than Pogo type pins.

[0164] In the example, the first electrical connection element 44 comprises two electrical contacts 50, which are metal plates extending perpendicular to the electrical contacts 48 of the second electrical connection element 46. Advantageously, the electrical contacts 50 are made with a ferromagnetic material.

[0165] When the screen 2 is in the retracted configuration, the electrical contacts 48 of a first of the two groups of two electrical contacts 48 of the second electrical connection element 46 are in contact with a first electrical contact 50 of the first electrical connection element 44 and the electrical contacts 48 of the second of the two groups of two electrical contacts 48 of the second electrical connection element 46 are in contact with the second electrical contact 50 of the first electrical connection element 44. In particular, the electrical contacts 48 are point-type contacts while the electrical contacts 50 in the form of metal plates are surface-type contacts. This allows an electrical connection without requiring precise alignment between the electrical contacts 48 and 50. Any misalignments of the load bar 8 relative to the holding device 9, 23 along the Z axis, but also along the X axis, are thus compensated.

[0166] Furthermore, the fact that the electrical contacts 48 are spring pins is particularly advantageous for ensuring a reliable electrical connection with the electrical contacts 50, because the spring of a spring pin makes it possible to push the pin of this spring pin against the corresponding electrical contact 50, making it possible to obtain a sufficient contact force for a reliable passage of an electric current.

[0167] In the example, the electrical power supply device 31 operates in direct current. Thus, a direct current flows between the first electrical connection element 44 and the second electrical connection element 46. In practice, the electrical contacts 48 of a first of the two groups of two electrical contacts 48 of the second electrical connection element 46 form a terminal positive and the electrical contacts 48 of the second of the two groups of two electrical contacts 48 of the second electrical connection element 46 form a negative terminal. Furthermore, a first electrical contact 50 of the first electrical connection element 44 forms a positive terminal and the second electrical contact 50 of the first electrical connection element 44 forms a negative terminal. In other words, the electrical contacts 48 of a first of the two groups of two electrical contacts 48 associated with a first electrical contact 50 form a positive pole and the electrical contacts 48 of the second of the two groups of two electrical contacts 48 associated with the second electrical contact 50 form a negative pole.

[0168] Advantageously, the electrical energy supply device 31 further comprises a photovoltaic solar panel 52, integrated or fixed to the charging bar 8. The photovoltaic solar panel 52 is oriented towards the opening 1 so as to be exposed to solar radiation, in particular when the screen 2 is in the deployed configuration.

[0169] Advantageously, the electrical energy supply device 31 further comprises a secondary battery 54, integrated or fixed to the charging bar 8. In [Fig. 4], the charging bar 8 is partially masked to make the secondary battery 54 visible.

[0170] The secondary battery 54 is electrically connected to the photovoltaic solar panel 52. Thus, the electrical energy generated by the photovoltaic solar panel 52 when it is exposed to solar radiation is stored by the secondary battery 54.

[0171] The secondary battery 54 is electrically connected to the first electrical connection element 44.

[0172] Thus, when the screen 2 is in the retracted configuration, that is to say in the high position, the secondary battery 54 is electrically connected to the main battery 24 via the first electrical connection element 44 and the second electrical connection element 46.

[0173] The secondary battery 54 then makes it possible to store the electrical energy generated by the photovoltaic solar panel 52 when the screen 2 is in the deployed configuration and then to transfer this electrical energy to the main battery 24 when the screen 2 is in the retracted configuration, i.e. in the high position.

[0174] In the example, the photovoltaic solar panel 52 is configured to produce, in other words produces, a direct current and the secondary battery 54 is configured to deliver, in other words delivers, a direct current to the first electrical connection element 44.

[0175] In practice, the secondary battery 54 has a lower electrical energy storage capacity than the main battery 24, for example corresponding to approximately 25% of the electrical energy storage capacity of the main battery 24.

[0176] Thus, the main battery 24 is rechargeable either from the external electrical power supply source 42, or from the photovoltaic solar panel 52 via the secondary battery 54. The photovoltaic solar panel 52 thus forms an internal electrical power supply source for the occultation device 3. In other words, the external electrical power supply source 42 and the photovoltaic solar panel 52 are two separate electrical power supply sources for recharging the main battery 24.

[0177] To ensure a reliable electrical connection between the first electrical connection element 44 and the second electrical connection element 46, and therefore between the main battery 24 and its two electrical energy supply sources 42, 52, the concealment device 3 further comprises a hooking device 60, shown in FIGS. 4 to 7.

[0178] The attachment device 60 is arranged at the level of the holding device 9, 23 of the screen 2 and makes it possible to exert a force F on the load bar 8 when the screen is in the high position, that is to say in the retracted configuration. The force F is exerted in a hooking direction DA comprising at least one component along the Y axis perpendicular to the movement axis Z and perpendicular to the rotation axis X. By "at the level of the holding device", it is meant that the attachment device 60 is integral with the holding device 9, 23, in particular the box 9, one of the cheeks 10 or one of the supports 23, or the torque support 21.

[0179] In the example, the force F is exerted along an axis Y which is perpendicular to the displacement axis Z and to the rotation axis X, i.e. perpendicular to the screen 2. In other words, in the example, the direction of attachment DA is parallel to the axis Y

[0180] The force F tends to bring the load bar 8 closer to the holding device 9, 23, in the hooking direction DA, to ensure cooperation between the first electrical connection element 44 and the second electrical connection element 46. In practice, the force F tends to press the electrical contacts 50 of the first electrical connection element 44 against the electrical contacts 48 of the second electrical connection element 46, that is to say it tends to put the first electrical connection element 44 in support, or in contact, against the second electrical connection element 46.

[0181] The load bar 8 is thus in the connection position when, under the effect of the force F generated by the attachment device 60, the load bar is pressed against, that is to say in mechanical contact with, the holding device 9, 23.

[0182] In a particularly advantageous manner, the electrical contacts 48 of the second electrical connection element 46 extend parallel to the hooking direction DA and the electrical contacts 50 of the first electrical connection element 44, formed by metal plates, extend substantially perpendicular to the hooking direction DA, making it possible to optimize their contact with the electrical contacts 50 of the first electrical connection element 44, in particular when the electrical contacts 48 of the second electrical connection element 46 are spring pins. Thus, the force F exerted by the hooking device 60 on the load bar 8 is exerted parallel to the force exerted by the spring of a spring pin 48 against the pin of this spring pin. The depression of the pins of each spring pin 48 by the support of the second electrical connection element 46 against the first electrical connection element 44 is then facilitated because the compression of the spring of each spring pin 48, under the effect of the force F, is facilitated, and makes it possible to obtain good electrical contact between the spring pins 48 and the metal plates 50.

[0183] In the example of the first embodiment, the attachment device 60 comprises a magnet 62, more precisely a permanent magnet, which is arranged at the level of the holding device 9, 23, and more precisely at the level of the second electrical connection element 46. In practice, the second electrical connection element 46 is fixed to the attachment device 60.

[0184] The force F exerted by the attachment device 60 on the load bar 8 when the screen 2 is in the retracted configuration corresponds to an attractive force exerted by the magnet 62 on the electrical contacts 50 of the first electrical connection element 44.

[0185] In practice, the magnet 62 is oriented so that the magnetic field generated by the magnet 62 is maximum along the direction of attachment DA.

[0186] Preferably, and as visible in [Fig.7], the magnet 62 is arranged between the two groups of electrical contacts 48 of the second electrical connection element 46. Thus, the magnet 62 is located opposite the electrical contacts 50 in the form of a metal plate of the first electrical connection element 44 when the screen 2 is in the retracted configuration.

[0187] The fact that the magnet 62 is arranged between the two groups of electrical contacts 48 of the second electrical connection element 46 is particularly advantageous for optimizing the approach between the first electrical connection element 44 and the second electrical connection element 46 and for optimizing the contact between the electrical contacts 48 and 50.

[0188] Alternatively, the magnet 62 is arranged behind the electrical contacts 48, in particular in a plane parallel to and offset from a plane on which the electrical contacts 48 are positioned.

[0189] As best seen in [Fig.5], the first electrical connection element 44 and the second electrical connection element 46 are opposite each other in the attachment direction DA and are approximately at the same height along the axis of displacement Z when the screen 2 is in the high position, that is to say in the retracted configuration. The force F exerted by the magnet 62 on the first electrical connection element 44 is thus maximized.

[0190] Preferably, the second electrical connection element 46 is located, parallel to the attachment direction DA, between the first electrical connection element 44 and the opening 1 when the screen 2 is in the retracted configuration.

[0191] To position the second electrical connection element 46 and the magnet 62, the attachment device 60 comprises a bracket 64, fixed to the holding device 9, 23. In the example, the bracket 64 is fixed to one of the two supports 23 by means of the fixing lug 23a. In other words, the bracket 64 is fixed to the fixing lug 23a. Thus, the second electrical connection element 46 is fixed to one of the two supports 23 by means of the fixing lug 23a and the bracket 64.

[0192] The bracket 64 comprises a first part 64a and a second part 64b. The first part 64a extends parallel to the attachment direction DA. The first part 64a is fixed to the fixing lug 23a by means of a slide 66 extending parallel to the attachment direction DA, which makes it possible to adjust the position of the bracket 64 relative to the fixing lug 23a, and therefore relative to the holding device 9, 23, parallel to the attachment direction DA. This adjustment of the position of the bracket 64 makes it possible to position the second connection element 46 so that it is located as close as possible to the first connection element 44, in the attachment direction DA, when the screen 2 is in the retracted configuration.Thus, the force F exerted by the magnet 62 on the first connection element 44 is maximized and the amplitude of the displacement of the end 8b of the load bar 8 towards the second connection element 44 is minimized, which minimizes a possible clicking noise during contact between the first and second electrical connection elements 44, 46. This adjustment of the position of the bracket also makes it possible to adapt, depending on the installations, the attachment device 60 to different winding diameters in the retracted configuration of the screen 2.

[0193] Advantageously, the attachment device 60 also comprises a cover 68 and a retaining screw 70. The cover 68 is hidden in [Fig.7]. The cover 68 is configured to cover, in other words covers, the slide 66. The retaining screw 70 is configured to be screwed, in other words is screwed, into the fixing lug 23a, passing through the cover 68 and the first part 64a of the bracket. Thus, the first part 64a of the bracket 64 is clamped between the fixing lug 23a and the cover 68 when the retaining screw 70 is screwed, so as to lock the position of the bracket 66 parallel to the attachment direction DA.

[0194] The second part 64b of the bracket 64 extends perpendicular to the first part 64a and parallel to the axis of rotation X of the electromechanical actuator 11. The second connection element 46, and more precisely the electrical contacts 48 of the second connection element 46, as well as the magnet 62, are fixed to the second part 64b of the bracket 64. Thus, under the effect of the force F, the end 8b of the load bar 8 approaches the bracket 64 when the screen 2 is in the retracted configuration.

[0195] The magnet 62 is advantageously fixed to the second part 64b so that the magnetic field generated by the magnet 62 is oriented in the attachment direction DA. In other words, the attachment direction DA is determined by the orientation and positioning of the magnet 62 relative to the first connection element 46 and to the second connection element 48.

[0196] Furthermore, thanks to the positioning of the magnet 62, the force F is exerted on the first connection element 46 only when the screen 2 is in the high configuration, that is to say in the rolled-up configuration, in other words in the retracted configuration. Indeed, when the screen 2 is in the deployed configuration, the first connection element 46 is distant from the magnet 62, along the movement axis Z, so that the magnet 62 does not exert any force on the first connection element 46. Thus, when the screen 2 is in the deployed configuration, the position of the load bar 8 is not affected by the attachment device 60.

[0197] In practice, during a rise of the screen 2 from its deployed configuration to its retracted configuration, the first connection element 46 enters the magnetic field of the magnet 62 when the screen 2 approaches its retracted configuration, for example when the load bar 8 is located less than 5 centimeters from the magnet 62, along the displacement axis Z. This value depends in particular on the dimensioning of the occulting device 3 and in particular on the force of attraction generated by the magnet 62, on the geometry of the bracket 64 and on the weight of the load bar 8.

[0198] Thus, during the end of the raising of the screen 2 from its deployed configuration to its retracted configuration, corresponding for example to the movement of the screen over the last 5 centimeters, the end 8a of the load bar 8 moves in a direction corresponding to the movement axis Z and punctually under the effect of the attraction of the magnet, according to the attachment direction DA: this movement therefore comprises a component carried by the movement axis Z, due to the traction generated by the electromechanical actuator 11 on the screen 2, and a component carried by the attachment direction DA, due to the force F generated by the magnet 62. According to the attachment direction DA, the load bar 8 thus moves in the direction of the holding device 9, 23 until it comes into mechanical contact with the holding device 9, 23, that is to say until it reaches its connection position.In the example, the load bar 8 moves in the hook direction DA until the . first electrical connection element 44 abuts against the second electrical connection element 46.

[0199] The attachment device 60 is configured to compensate, in other words compensates, for an offset between the first electrical connection element 44 and the second electrical connection element 46, parallel to the attachment direction DA, i.e. perpendicular to the screen 2, when the screen 2 reaches its retracted configuration, i.e. its high configuration. Thus, when the screen 2 reaches the retracted configuration, the attachment device 60 makes it possible to ensure the electrical connection between the first electrical connection element 44 and the second electrical connection element 46.

[0200] The fact that the force F generated by the magnet 62 on the first electrical connection element 44 is transverse, preferably perpendicular, to the displacement axis Z, is particularly advantageous for allowing effective rapprochement between the first electrical connection element 44 and the second electrical connection element 46 without disturbing the movement of the screen 2 from its deployed configuration to its retracted configuration along the displacement axis Z. Furthermore, when the screen 2 is moved from its retracted configuration to its deployed configuration, in other words when the screen 2 is deployed, or lowered, this orientation of the force F makes it possible to avoid opposing the movement of the screen 2 by making it possible to prevent the first electrical connection element 44 from remaining attached to the second electrical connection element 46.Thus, the simple weight of the load bar generates a force along the Z axis which releases it from the force F generated by the magnet 62. In particular, this release of the load bar 8 during the descent of the screen is facilitated by the fact that the magnet 62 exerts a force F on the load bar which is oriented perpendicular to the axis of movement Z: the magnetic field generated by the magnet 62 being oriented along the direction of attachment DA, this magnetic field is weakest perpendicular to the direction of attachment 62 and therefore parallel to the axis of movement Z. Thus, the magnet 62 exerts a minimal force on the load bar 8 along the axis of movement Z and does not prevent the descent of the load bar under its own weight.

[0201] Furthermore, the fact that the first electrical connection element 44 and the second electrical connection element 46 are opposite each other, or at the same height, along the movement axis Z when the screen 2 is in the retracted configuration is particularly advantageous in avoiding having to use an elastic element to ensure the electrical connection between the first electrical connection element 44 and the second electrical connection element 46, which is more reliable and more aesthetic, the movement of the end 8b of the load bar 8 being more discreet for a user of the occulting device 3.

[0202] The construction of the occulting device 3, and more precisely of the electrical power supply device 31 and of the attachment device 60, makes it possible to reach the second electrical connection element 46 arranged at the level of the holding device 9, 23 of the screen 2 by the first electrical connection element 44, following a movement of the screen 2 to the retracted configuration, while compensating for any offset of the first electrical connection element 44 relative to the second electrical connection element 46 perpendicular to the screen 2 by means of the attractive force of the magnet 62.

[0203] Consequently, the construction of the concealment device 3 makes it possible to guarantee simplified and ergonomic recharging of electrical energy for the user of the main battery 24 from the external electrical energy supply source 42 and / or from the photovoltaic solar panel 52.

[0204] Furthermore, the construction of the concealment device makes it possible to avoid a user having to climb a stepladder to access the second electrical connection element 46 arranged at the level of the holding device 9, 23 of the screen 2 when the main battery 24 is recharged from the external electrical power supply source 42.

[0205] Indeed, the electrical power supply cable 43 electrically connecting the external electrical power supply source 42 to the charging connector 40 is driven by the movement of the screen 2, by means of the electromechanical actuator 11, to the retracted configuration, that is to say to the high position of the screen 2.

[0206] Furthermore, the electrical connection of the external electrical power supply source 42 to the first electrical connection element 44 to the charging connector 40 is facilitated, since this electrical connection can be implemented by simple electrical contact when the screen 2 is in a deployed configuration or in a low end-of-travel position, in other words without having to climb onto a stepladder to access the charging connector 40 or without insertion effort between male and female type parts at the level of the holding device 9, 23.

[0207] Furthermore, the construction of the electrical power supply device 31 makes it possible to improve the aesthetics of the occultation device 3, since the second electrical connection element 46 can be integrated at the level of the holding device 9, 23 of the screen 2 and a daylight, that is to say a gap through which light can pass, can be minimized between the screen 2 and the holding device 9, 23 of the screen 2.

[0208] In addition, the main battery 24 can be recharged without having to dismantle a part of the occulting device 3 and, in particular, of the holding device 9, 23 of the screen 2, in particular of the box 9 of the occulting device 3.

[0209] Here, the occultation device 3 being a roller blind, the bracket 64 makes it possible to take into consideration an offset between the first electrical connection element 44 and the second electrical connection element 46 linked to the winding diameter of the screen 2 around the winding tube 4, in particular parallel to the hanging direction DA. This diameter is in particular defined by a thickness of the fabric forming the screen 2, a number of turns of winding of the screen 2 around the winding tube 4 and a diameter of the winding tube 4. Advantageously, during the installation of the occultation device 3, the bracket 64 is adjusted, using the slide 66, to minimize the offset between the first electrical connection element 44 and the second electrical connection element 46 and to facilitate the movement of one towards the other in the retracted configuration of the screen 2.

[0210] Advantageously, the retracted configuration of the screen 2 can be determined during the installation of the occulting device 3.

[0211] In an exemplary embodiment, the retracted configuration can be determined as having been reached by means of a counting device, notably identifying the number of revolutions traveled and the angle of rotation of the output shaft 20 of the electromechanical actuator 11, the number of revolutions traveled and the angle of rotation of the rotor of the electric motor 16 or even the operating time of the electromechanical actuator 11.

[0212] Alternatively, the retracted configuration of the screen 2 may be determined as reached by means of the stop and / or obstacle detection device of the electromechanical actuator 11.

[0213] For example, the retracted configuration of the screen 2 is defined by the mechanical contact of the load bar 8 against the holding device 9, 23.

[0214] Advantageously, the retracted configuration of the screen 2 is determined to be reached when the electrical connectors 50 of the first electrical connection element 44 are electrically connected to the electrical connectors 48 of the second electrical connection element 46, so as to send a signal to the electronic control unit 15.

[0215] Thus, following receipt of this signal by the electronic control unit 15, the latter issues a command to stop the electromechanical actuator 11.

[0216] In the different variants, the movement of the first electrical connection element 44 relative to the second electrical connection element 46 is controlled by the electronic control unit 15 and, more particularly, by the movement of the screen 2 through the electromechanical actuator 11.

[0217] In a variant of the invention not shown, the occultation device 3 does not comprise a photovoltaic panel 52 or a secondary battery 54.

[0218] In a variant of the invention not shown, the occultation device 3 does not comprise no charging connector 40.

[0219] In a variant of the invention that is not shown, the first electrical connection element 44 comprises four electrical contacts 50, which are Pogo-type pins grouped into two groups of two electrical contacts, the two electrical contacts of the same group being electrically connected to each other, and the second electrical connection element 46 comprises two electrical contacts 48, which are metal plates, made with a ferromagnetic material.

[0220] In a variant of the invention that is not shown, when the screen 2 is in the retracted configuration and the load bar 8 is in the connection position, the first electrical connection element 44 and the second electrical connection element 46 are not aligned along the Y axis, but are aligned, i.e. are opposite each other, along the rotation axis X. In other words, in such a variant, the first connection element 44 is located at one end of the load bar 8. In such a variant, the magnet 62 is arranged so that the force F exerted by the magnet on the load bar is oriented parallel to the rotation axis X. In other words, in such a variant, the attachment direction DA is parallel to the rotation axis X and the load bar is moved by the attachment device 60 in a plane formed by the rotation axis X and the movement axis Z.

[0221] In a variant of the invention that is not shown, the electrical connection between the first electrical connection element 44 and the second electrical connection element 46 is made by induction, i.e. without contact. In such a variant, the mechanical contact between the load bar and the holding device 9, 23 is useful for improving the efficiency of the transmission of energy by induction between the first and second electrical connection elements 44, 46, by controlling, for example by reducing, the distance between them.

[0222] A concealment device 3 according to a second embodiment of the invention is now described with reference to [Fig. 8]. In the second embodiment, elements similar to those of the first embodiment bear the same references and operate in the same way. In the following, the differences between the first and second embodiments are mainly described.

[0223] Furthermore, if a component is mentioned in the description of the second embodiment without being shown in [Fig.8], it corresponds to the same element shown in Figures 1 to 7 for the first embodiment.

[0224] In the second embodiment, the concealing device 3 comprises a hooking device 60'. As with the hooking device 60 of the first embodiment, the hooking device 60' makes it possible to exert a force F on the load bar 8 when the screen 2 is in the high configuration, i.e. in the retracted configuration. The force F is exerted in the hooking direction DA which comprises at least a component along the Y axis, and at least one component along the Z displacement axis. Here, as in the first embodiment, the Y axis is perpendicular to the Z displacement axis and perpendicular to the X rotation axis.

[0225] In the second embodiment, the attachment device 60' comprises a bearing surface 80 extending in a plane P80 parallel to the rotation axis X and oblique to the movement axis Z. This bearing surface is perpendicular to the attachment direction DA.

[0226] The support surface 80 is fixed relative to the holding device 9, 23. In the example, the support surface 80 is provided on the box 9.

[0227] During the raising of the screen 2 from its deployed configuration to its retracted configuration, when the screen 2 approaches its retracted configuration, then the load bar 8 comes into contact with the support surface 80. This configuration is shown in insert A) of [Fig.8].

[0228] Then, as the screen 2 continues to be rolled up, the load bar 8 slides against the bearing surface 80 until the retracted configuration of the screen 2 is reached, as shown in insert B) of [Fig. 8]. The load bar 8 is thus brought closer to its connection position.

[0229] Thus, the load bar 8 moves along a sliding axis Y80, the sliding axis Y80 being carried by the plane P80 and perpendicular to the rotation axis X.

[0230] In other words, the orientation of the support surface 80 makes it possible to generate the force F oriented in the direction of attachment DA in reaction to a force Fil exerted by the electromechanical actuator 11 on the screen 2 and on the load bar 8.

[0231] The movement of the load bar 8 during its sliding against the support surface 80, represented by the arrow F80 on the inserts A) and B) of [Fig.8], thus corresponds to the sum of the force F oriented in the direction of attachment DA and the force Fil exerted by the electromechanical actuator 11 on the screen 2 and on the load bar 8.

[0232] Thanks to the force F, as in the first embodiment, the first electrical connection element 44 is brought closer to the second electrical connection element 46 in an offset movement carried by the hooking direction DA and integrating a component along the Y axis, making it possible to ensure electrical contact between the first electrical connection element 44 and the second electrical connection element 46 along this Y axis.

[0233] In the example of the second embodiment, the first electrical connection element 44 comprises two electrical contacts 50 and the second electrical connection element 46 comprises two electrical contacts 48 complementary to the electrical contacts 50. For example, the electrical contacts 48 are spring pins and the electrical contacts 50 are metal plates, or vice versa. alternatively, other types of electrical contacts are possible.

[0234] In particular, metal tracks (not shown) can be installed along the bearing surface 80 and can cooperate with spring pins located on one face of the load bar 8 opposite the bearing surface 80.

[0235] Advantageously, the bearing surface 80 is formed in the cheek 10 of the box 9 located at the end 8b of the load bar 8, along the axis of rotation X. Thus, the end 8b of the load bar 8 slides against the bearing surface 80 when the screen 2 approaches its retracted configuration. Thus, the end 8b of the load bar 8 is brought closer to the second electrical connection element 46 and therefore to the holding device 9, 23 thanks to the force F.

[0236] Alternatively, the support surface 80 is provided on an independent support. The position and / or inclination of the support surface is thus adjustable.

[0237] Advantageously, the attachment device 60' further comprises a housing 82, located in the continuity of the support surface 80. Thus, when the screen 2 approaches its retracted configuration, the support surface 80 guides the end 8b of the load bar 8 towards the housing 82, so that, when the screen 2 is in the retracted configuration, the end 8b of the load bar 8 is received in the housing 82.

[0238] The housing 82 has a shape complementary to that of the end 8b of the load bar 8. In the example, the end 8b of the load bar 8 has a circular section and the housing 82 also has a circular shape.

[0239] In practice, the second electrical connection element 46, and thus the electrical contacts 48', are arranged in the housing 82.

[0240] Advantageously, the first electrical connection element 44 and the second electrical connection element 46 are arranged so as to be located opposite each other along the movement axis Z when the screen 2 is in the retracted configuration.

[0241] In a variant not shown of the second embodiment, the attachment device 60' further comprises a magnet, configured to bring the first electrical connection element 44 closer to the second electrical connection element 46 when the screen 2 is in the retracted configuration. The magnet is, for example, arranged in the housing 82 or on the support surface 80.

[0242] Furthermore, the embodiments and variations contemplated may be combined to generate new embodiments of the invention, without departing from the scope of the invention.
