Description

Title of the invention: Blackout device

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

[0002] In general, the present invention relates to the field of blackout devices comprising a motorized drive device moving a screen, between at least a first position and at least a second position.

[0003] A motorized drive device includes an electromechanical actuator of a movable closing, obscuring or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter referred to as a screen.

[0004] Blackout devices comprising a housing, a screen, a roller tube, and an electrical energy storage device are already known. The screen is rollable onto the roller tube. The roller tube is located inside the housing. The housing comprises a first wall and a second wall. The first wall of the housing comprises a first inner surface. The second wall is connected to the first wall. The second wall of the housing comprises a second inner surface. The electrical energy storage device comprises a battery and two supports. The battery is located inside the housing. The battery comprises an outer surface. Each support is fixed against the first inner surface of the first wall of the housing by means of at least one fastener and, on the other hand, holds the battery in position inside the housing. Each support comprises a first arm and a second arm.The first arm comprises a first surface. The first surface of the first arm is pressed against the first inner surface of the first wall of the chest. The second arm is connected to the first arm. The second arm comprises a second surface. The second surface of the second arm is pressed against the outer surface of the battery. The second surface of the second arm is curved.

[0005] However, these concealment devices have the disadvantage that each support holds the battery in position inside the box by elastic snap-fit ​​and that each support is held in a closed state by means of an elastic band, hooking onto two hooks of each support, to prevent translational movement of the battery inside each of the supports.

[0006] Thus, such supports require a significant number of operations to be performed by an installer. Furthermore, the cost of these supports is high.

[0007] The operations to be carried out by the installer when mounting the battery inside the housing of these known blackout devices are as follows:

[0008] - a first operation of fixing each support against the first surface in exterior of the first wall of the trunk, by means of at least one fixing element, by gluing, screwing or riveting,

[0009] - a second operation of fixing the battery onto each of the supports by elastic ratchet,

[0010] - a third operation of attaching an elastic band to a first hook of each support, and

[0011] - a fourth operation of attaching the elastic to a second hook of each support.

[0012] Furthermore, the second arm of each support is positioned between the battery and the first and second inner surfaces of the first and second walls of the trunk. Only the elastic band of each support is positioned between the battery and the screen.

[0013] Furthermore, the second surface of the second arm of each support is oriented towards a third wall of the chest, the third wall being connected to the first wall and, in this case, parallel to the second wall.

[0014] The present invention aims to resolve the aforementioned drawbacks and to propose a blackout device allowing a battery to be mounted inside a box of the blackout device, while minimizing the number of operations to be carried out by an installer, minimizing the time of intervention of the installer and minimizing the cost of the installation of the blackout device, with a low cost of the supports.

[0015] In this regard, the present invention relates to a blackout device comprising at least:

[0016] - a chest,

[0017] - a screen,

[0018] - a winding tube, the screen being windable onto the winding tube, the tube the winding mechanism being located inside the box, and

[0019] - an electrical energy storage device,

[0020] the safe comprising at least:

[0021] - a first wall, the first wall comprising at least a first surface interior, and

[0022] - a second wall, the second wall being connected to the first wall, the second wall comprising at least a second interior surface,

[0023] the electrical energy storage device comprising at least:

[0024] - a battery, the battery being located inside the trunk, the battery comprising at least one exterior surface, and

[0025] - two supports, each support being fixed against the first inner surface of the first wall of the trunk, by means of at least one fastening element, and each support holding the battery in position inside the trunk,

[0026] each support comprising at least:

[0027] - a first arm, the first arm comprising at least one first surface, the the first surface being placed against the first inner surface of the first wall of the chest, and

[0028] - a second arm, the second arm being connected to the first arm comprising at least a second surface, the second surface being placed against the outer surface of the battery, the second surface being curved.

[0029] According to the invention, the second arm of each support is arranged between the battery and the screen. Furthermore, the battery is held against the first inner surface of the first wall of the trunk and against the second inner surface of the second wall of the trunk, by means of the second surface of the second arm of each support.

[0030] Thus, the supports allow the battery to be mounted inside the trunk, while minimizing the number of operations to be carried out by an installer, minimizing the time of intervention of the installer and minimizing the cost of the installation of the blackout device, with a low cost of the supports.

[0031] In addition, each support allows the battery to be positioned as close as possible to one of the corners of the trunk, formed by the first and second walls connected together, so as to optimize the size of the electrical energy storage device inside the trunk and to move the battery away from the screen, when the latter is being wound or unwound around the winding tube inside the trunk.

[0032] In this way, the electrical energy storage device can be installed in a box of smaller dimensions, in particular in terms of thickness and height.

[0033] Consequently, the small size of the electrical energy storage device inside the trunk makes it possible, on the one hand, to avoid contact of the screen, when winding or unwinding it around the winding tube inside the trunk, with the battery and, on the other hand, to maximize a winding diameter of the screen around the winding tube inside the trunk.

[0034] Furthermore, each support helps to protect the battery, by preventing contact of the screen, when winding or unwinding it around the winding tube inside the box, with the battery.

[0035] In this way, each support is a protective element for the battery in relation to the screen.

[0036] According to an advantageous feature of the invention, the battery is cylindrical.

[0037] According to another advantageous feature of the invention, each support is made of a plastic material.

[0038] According to another advantageous feature of the invention, the fixing element of each support against the first wall of the chest is a fixing element by collage.

[0039] According to another advantageous feature of the invention, the fixing element of each support against the first wall of the chest is a fixing element by screwing or riveting.

[0040] According to another advantageous feature of the invention, the second wall is orthogonal to the first wall of the chest.

[0041] According to another advantageous feature of the invention, the second arm of each support further comprises a third surface, the third surface being opposite the second surface.

[0042] According to another advantageous feature of the invention, each support further comprises at least one stiffening element, the stiffening element connecting the first arm to the second arm.

[0043] According to another advantageous feature of the invention, the shading device further comprises at least one motorized drive device. The motorized drive device comprises at least one electromechanical actuator. The electromechanical actuator comprises at least one electric motor, the electric motor being powered by the battery. In addition, the winding tube is arranged so as to be driven in rotation by the electromechanical actuator.

[0044] According to another advantageous feature of the invention, the shading device further comprises at least one photovoltaic panel, the battery being supplied with electrical energy by means of the photovoltaic panel.

[0053] A home automation system 100 according to the invention is described first, with reference to Figures 1 and 2. This home automation system 100 comprises at least one closing, shading, or solar protection device 3, according to one embodiment of the invention. This home automation system 100, installed in a building (not shown), has an opening 1, in which a window 40 or a door is located (the latter is shown only in Figure 1). This home automation system 100 is equipped with at least one screen 2 belonging to the closing, shading, or solar protection device 3, in particular a motorized roller shutter.

[0054] The closing, shading or sun protection device 3 is hereinafter referred to as the "shading device". The shading device 3 comprises the screen 2.

[0055] The shading device 3 can be a roller shutter, a fabric blind or a blind with adjustable slats, a rolling gate, a grille, or even a door. The present invention applies to all types of shading devices.

[0056] A roller shutter conforming to the embodiment of the invention is described with reference to figures 1 and 2.

[0057] The occulting device 3 includes a motorized drive device 5. The motorized drive device 5 includes an electromechanical actuator 11 illustrated in [Fig.3].

[0058] The occultation device 3 further comprises a winding tube 4. The screen 2 is windable onto the winding tube 4. In addition, the winding tube 4 is arranged so as to be driven in rotation by the electromechanical actuator 11.

[0059] Thus, the screen 2 of the occulting device 3 is wound on the winding tube 4 or unwound around it, the winding tube 4 being driven by the motorized drive device 5, in particular by the electromechanical actuator 11.

[0060] In this way, the screen 2 is mobile between a rolled-up position, in particular high, and an unrolled position, in particular low, and vice versa.

[0061] The screen 2 of the shading device 3 is a closing, shading and / or solar protection screen, rolling and unrolling around the winding tube 4, of which the inner diameter is greater than the outer diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, when assembling the blackout device 3.

[0062] The electromechanical actuator 11, in particular of tubular type, allows the winding tube 4 to be rotated around an axis of rotation X, so as to move, in particular unwind or wind, the screen 2 of the occulting device 3.

[0065] The occultation device 3 further comprises a box 9.

[0066] In the case of a roller shutter, the raised, fully retracted position corresponds to the bearing of an end slat 8, for example L-shaped, of the curtain 2 of the roller shutter 3 against an edge of the housing 9 of the roller shutter 3, or to the stopping of the end slat 8 in a programmed upper limit position. Furthermore, the lower, fully retracted position corresponds to the bearing of the end slat 8 of the curtain 2 of the roller shutter 3 against a threshold 7 of the opening 1, or to the stopping of the end slat 8 in a programmed lower limit position.

[0067] Here, the screen 2 is configured to be moved, by means of the motorized drive device 5, between an open position, corresponding to the rolled-up position and which can also be called the first end-of-stroke position or upper end-of-stroke position FdCH, and a closed position, corresponding to the unrolled position and which can also be called the second end-of-stroke position or lower end-of-stroke position FdCB.

[0068] Thus, the electromechanical actuator 11 is configured to drive, in other words drives, in movement the screen 2, between the first end position FdCH and the second end position FdCB, and vice versa.

[0148] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive a connecting element 22 in rotation. This connecting element 22 is connected to the winding tube 4, in particular in the assembled configuration of the occulting device 3. The connecting element 22 is, for example, made in the form of a wheel.

[0149] When the electromechanical actuator 11 is switched on, 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 22.

[0150] Thus, the winding tube 4 causes the screen 2 of the occulting device 3 to rotate, so as to open or close the opening 1.

[0151] Advantageously, the obscuring device 3 and, more particularly, the motorized drive device 5 further comprises a power supply device electrical 26, visible in [Fig.2]. The electromechanical actuator 11 is electrically connected to the electrical power supply device 26.

[0157] Thus, the electrical power supply device 26 and, more particularly, the battery 24 makes it possible to supply electrical power to the electromechanical actuator 11, without itself being electrically connected to a mains power supply network.

[0158] Here, the photovoltaic panel 25 is electrically connected to the battery 24, by an electrical connection L.

[0159] The electromechanical actuator 11 is electrically connected to the electrical power supply device 26 and, more particularly, to the battery 24, in particular by means of the electrical power supply cable 18.

[0161] Thus, the charging of the battery 24 is carried out by solar energy, by means of the photovoltaic panel 25.

[0162] Battery 24 is located inside trunk 9.

[0163] In [Fig.2], the battery 24 is shown outside the trunk 9 in order to better visualize the components of the electrical power supply device 26. This is independent of the location of the battery 24 inside the trunk 9.

[0164] When the torque support 21 includes a display device, the operating parameter that this display device allows to be viewed is advantageously a state of charge of the battery 24.

[0165] Here, the electromechanical actuator 11 includes the power supply cable 18 enabling its electrical power supply, in particular the power supply of the electronic control unit 15 and the power supply of the electric motor 16, in particular from the battery 24.

[0166] Here, the battery 24 is electrically connected directly to the electronic control unit 15, by the power supply cable 18.

[0167] Advantageously, the battery 24 comprises a plurality of energy storage elements 32, in particular electrically connected in series. The energy storage elements 32 of the battery 24 may be, in particular, accumulators or cells.

[0168] Advantageously, the photovoltaic panel 25 comprises a plurality of photovoltaic cells 43. In this case, the battery 24 is supplied with electrical energy by means of the photovoltaic cells 43 of the photovoltaic panel 25.

[0169] The motorized drive device 5, in particular the photovoltaic panel 25 and / or the electronic control unit 15, includes charging elements configured to charge the battery 24, from the solar energy recovered by the photovoltaic panel 25. In this case, the current flows between the organs 15, 24 and 25 through a wired link, which may be separate from the electrical power supply cable 18.

[0170] Thus, the charging elements configured to charge the battery 24, from solar energy, make it possible to convert the solar energy recovered by the photovoltaic panel 25 into electrical energy.

[0171] Alternatively, in addition, the motorized drive device 5, in particular the electromechanical actuator 11, is supplied with electrical energy from an auxiliary battery, not shown, or from a mains power supply network, in particular from the commercial AC network, in particular depending on a state of charge of the battery 24.

[0172] Here, the electronic control unit 15 comprises a single electronic board 55. Furthermore, the electronic board 55 is configured to control the electric motor 16, to enable the charging of the battery 24, and optionally, to access parameterization and / or configuration functions of the electromechanical actuator 11, by means of selection and, optionally, display elements, not shown.

If the electronic control unit 15 comprises a first and a second electronic board, not shown, the first electronic board of the electronic control unit 15 can be located inside the housing 17 of the electromechanical actuator 11. Furthermore, the second electronic board can be located inside the torque support 21 of the electromechanical actuator 11. The torque support 21 may also include a cover, not shown. In addition, the second electronic board can be located inside a recess formed between a portion of the torque support 21 and the cover.

[0174] Advantageously, the photovoltaic panel 25 can be fixed on the box 9, on a wall of the building, on one of the side rails 6, on a pane of glass of the window 40 or on a fixed frame of the window 40.

[0175] The electrical energy storage device 33 belonging to the occultation device 3 illustrated in Figures 1 and 2, as well as the mounting of the battery 24 against the box 9, are now described in more detail and with reference to Figures 4 to 7.

[0176] The box 9 comprises at least a first wall 9a and a second wall 9b. The second wall 9b is connected, or rather configured to be connected, to the first wall 9a, particularly in the assembled configuration of the obscuring device 3. The first wall 9a comprises at least a first interior surface 9ai. Furthermore, the second wall 9b comprises at least a second interior surface 9bi.

[0177] The first and second walls 9a, 9b of the chest 9 are connected to each other either by fastening elements, not shown, which may be, for example, fastening elements by interlocking, by elastic snap-fit, by riveting or by screwing, or because they belong to the same strip of sheet metal or form a single piece, in particular made of plastic.

[0178] Advantageously, the chest 9 is defined by a length L9, a height H9 and a thickness E9, in other words a depth.

[0179] The battery 24 comprises at least one external surface 24e.

[0180] The electrical energy storage device 33 further comprises at least two supports 37. Each support 37 is fixed against the first inner surface 9ai of the first wall 9a of the box 9, by means of at least one fixing element 38. In addition, each support 37 holds the battery 24 in position inside the box 9.

[0181] Here, the two supports 37 are identical. The following description of a support applies to either of these two supports 37.

[0182] Each support 37 comprises at least a first arm 41 and a second arm 42. The first arm 41 comprises at least a first surface 41a. The first surface 41a is configured to be supported, in other words, is supported, against the The first inner surface 9ai of the first wall 9a of the chest 9, particularly in the assembled configuration of the occultation device 3. The second arm 42 is connected to the first arm 41. The second arm 42 includes at least one second surface 42a. The second surface 42a is configured to be supported, that is to say, is supported, against the outer surface 24e of the battery 24, particularly in the assembled configuration of the occultation device 3. In addition, the second surface 42a is curved, that is to say, has a concavity.

[0183] Here, the concavity of the second surface 42a is oriented towards battery 24, in particular in the assembled configuration of the occultation device 3.

[0184] The second arm 42 of each support 37 is disposed, in other words is configured to be disposed, between the battery 24 and the screen 2, in particular in the assembled configuration of the occulting device 3.

[0185] In addition, the battery 24 is held in support, in other words is configured to be held in support, against the first inner surface 9ai of the first wall 9a of the chest 9 and against the second inner surface 9bi of the second wall 9b of the chest 9, by means of the second surface 42a of the second arm 42 of each support 37, in particular in the assembled configuration of the occulting device 3.

[0186] Thus, the supports 37 allow the battery 24 to be mounted inside the trunk 9, while minimizing the number of operations to be carried out by an installer, minimizing the time of intervention of the installer and minimizing the cost of the installation of the blackout device 3, with a low cost of the supports 37.

[0187] The first and second walls 9a, 9b of chest 9 connected together form one of the angles 44a, 44b, 44c, 44d of chest 9.

[0188] Advantageously, the case 9 has an opening 48 for the passage of the screen 2 when winding and unwinding the latter around the winding tube 4, as illustrated in [Fig.4].

[0189] Advantageously, chest 9 includes a third wall 9c and a fourth wall 9d.

[0190] Here and as illustrated in [Fig.2], chest 9 is parallelepiped in shape and has four angles 44a, 44b, 44c, 44d, including an upper right angle 44a, an upper left angle 44b, an lower right angle 44c and an lower left angle 44d.

[0191] Alternatively, and as illustrated in [Fig. 4], the chest 9 is parallelepiped in shape and has three angles 44a, 44b, 44c, including an upper left angle 44a, an upper right angle 44b, and a lower right angle 44c. The lower right angle 44c has a large radius of curvature to connect the third and fourth walls 9c, 9d of the chest 9. In this case, the chest 9 lacks a lower left angle 44d, since the first wall 9a and the fourth wall 9d are not contiguous, so as to form the opening 48.

[0192] In addition, each support 37 allows the battery 24 to be positioned as close as possible to one of the corners 44a, 44b, 44c, 44d of the box 9, formed by the first and second walls 9a, 9b connected together, so as to optimize the size of the electrical energy storage device 33 inside the box 9 and to move the battery 24 away from the screen 2, when the latter is wound or unwound around the winding tube 4 inside the box 9.

[0193] In this way, the electrical energy storage device 33 can be installed in a box 9 of smaller dimensions, in particular in terms of thickness E9 and height H9.

[0194] Consequently, the small size of the electrical energy storage device 33 inside the box 9 makes it possible, on the one hand, to avoid contact of the screen 2, when winding or unwinding it around the winding tube 4 inside the box 9, with the battery 24 and, on the other hand, to maximize a winding diameter 02 of the screen 2 around the winding tube inside the box 9. A circle of diameter 02, which delimits the maximum size of the screen 2 inside the box 9, is represented by a dashed line in [Fig.4].

[0195] In the embodiment illustrated in figures 4 and 5, each support 37 allows the battery 24 to be positioned as close as possible to the angle 44a of the box 9.

[0196] As an alternative, not shown, each support 37 allows the battery 24 to be positioned as close as possible to angle 44b, angle 44c or angle 44d of the trunk 9.

[0197] Furthermore, each support 37 helps to protect the battery 24, by preventing contact of the screen 2, when winding or unwinding it around the winding tube 4 inside the box 9, with the battery 24.

[0198] In this way, each support 37 is a battery protection element 24 in relation to the screen 2.

[0199] Advantageously, each support 37 is made of a plastic material.

[0200] Thus, each support 37 made of plastic material prevents damage to the battery 24, when installing it inside the trunk 9, by means of the supports 37, in particular compared to supports made of metal, which could have sharp edges.

[0201] In addition, in the event of damage to the battery 24, during its installation inside the trunk 9, each support 37 made of plastic material prevents the creation of a short circuit in the battery 24, which could generate a chemical reaction at the level of its electrical energy storage elements 32, since each support 37 is not electrically conductive.

[0202] Advantageously, battery 24 is cylindrical, in other words, has a circular cross-section.

[0203] Here, battery 24 is defined by an outside diameter 024, which is the outside diameter of its outer surface 24e.

[0204] Advantageously, the outer diameter 024 of the battery 24 is within a predetermined range of values, the predetermined range of values ​​being defined between a first minimum value and a second maximum value.

[0205] Thus, each support 37 is compatible with different outside diameter values ​​024 of the battery 24, so as to be universal within the predetermined range of values.

[0206] In this way, a single reference support 37 is developed and marketed for the different reference batteries 24 developed and marketed intended to be installed in the trunk 9.

[0207] Advantageously, the first minimum value of the range is greater than or equal to ten millimeters, preferably greater than or equal to thirteen millimeters, and the second maximum value of the range is less than or equal to fifty millimeters, preferably less than or equal to forty millimeters.

[0208] By way of non-limiting example, the value of the outside diameter 024 of battery 24 may be seventeen millimeters or twenty-three millimeters.

[0209] Here and as illustrated in [Fig.5], the electrical energy storage device 33 comprises two supports 37.

[0210] In an alternative, not shown, the electrical energy storage device 33 comprises three or more supports 37, in particular depending on a length L24 of the battery 24.

[0211] Thus, the supports 37, two or more of them, make it possible to guarantee an alignment of the battery 24 inside the trunk 9 and, more particularly, as close as possible to one of the corners 44a, 44b, 44c, 44d of the trunk 9.

[0212] Advantageously, the length L9 of the chest 9 is greater than or equal to one hundred and twenty-five millimeters, in particular when the value of the outside diameter 024 of the battery 24 is on the order of seventeen millimeters.

[0213] Advantageously, the second surface 42a of the second arm 42 of each support 37 is oriented, in other words is configured to be oriented, on the one hand, towards the second wall 9b of the chest 9 and, on the other hand, towards the first wall 9a of the chest 9, in particular in the assembled configuration of the occultation device 3.

[0214] Here, the first and second walls 9a, 9b of chest 9 are contiguous, in other words adjacent, so as to form one of the angles 44a, 44b, 44c, 44d of chest 9.

[0215] Advantageously, the second wall 9b of chest 9 is orthogonal to the first wall 9a of chest 9.

[0216] Thus, the angle 44a formed by the first and second walls 9a, 9b of the chest 9 is a right angle, in other words at 90°.

[0217] Alternatively, not shown, the angle 44a formed by the first and second walls 9a, 9b of the chest 9 can be an angle with a value greater or less than 90°, for example of the order of 100° or of the order of 80°.

[0218] Advantageously, the curvature of the second surface 42a of the second arm 42 of each support 37 is defined so as to be coincident, in other words so as to be in point contact, with a part of the outer surface 24e of the battery 24, regardless of the value of the outer diameter 024 of the battery 24 included in the predetermined range of values.

[0219] Thus, the curvature of the second surface 42a of the second arm 42 of each support 37 makes it possible to guarantee that the battery 24 is wedged against the first inner surface 9ai of the first wall 9a of the chest 9 and against the second inner surface 9bi of the second wall 9b of the chest 9, regardless of the value of the outer diameter 024 of the battery 24 within the predetermined range of values, in particular in the assembled configuration of the occultation device 3.

[0220] Advantageously, the second arm 42 of each support 37 further comprises a third surface 42b. The third surface 42b is opposite the second surface 42a.

[0221] In other words, in the assembled configuration of the occulting device 3, the third surface 42b is oriented towards the winding tube 4 and, possibly, towards the portion of the screen 2 wound on this winding tube 4.

[0222] Thus, the third surface 42b of the second arm 42 of each support 37 makes it possible to protect the battery 24, by preventing contact of the screen 2 with the battery 24, when winding or unwinding it around the winding tube 4 inside the box 9.

[0223] In this way, the third surface 42b of the second arm 42 of each support 37 is a battery protection face 24 relative to the screen 2.

[0224] Advantageously, each support 37 further comprises at least one stiffening element 45. In addition, the stiffening element 45 connects the first arm 41 to the second arm 42.

[0225] Here, each support 37 comprises two stiffening elements 45.

[0226] Advantageously, each stiffening element 45 is made in the form of a rib.

[0227] Here, the first and second arms 41, 42 and the two stiffening elements 45 of each support 37 form a single piece. In other words, each support 37 is a single piece consisting of the first and second arms 41, 42 and the two stiffening elements 45.

[0228] Alternatively, not shown, the first and second arms 41, 42 and the two stiffening elements 45 of each support 37 are separate parts as joined together by means of at least one fastening element, which may be, for example, by elastic snap-fit, by interlocking or by screwing.

[0229] Advantageously, the fixing element 38 of each support 37 against the first wall 9a of the chest 9 is a fixing element by bonding.

[0230] Thus, in this case, fixing each support 37 against the first wall 9a of the chest 9 does not require any tools.

[0231] Alternatively or in addition, the fixing element of each support 37 against the first wall 9a of the chest 9 is a fixing element by screwing or riveting.

[0232] Advantageously, in the case where the fixing of each support 37 against the first wall 9a of the chest 9 is implemented by screwing or riveting, the first arm 41 of each support 37 includes a through hole 46.

[0233] Thus, the through hole 46 allows the passage of a screw or rivet through the first arm 41 of each support 37, so as to screw or rivet each support 37 against the first wall 9a of the chest 9.

[0234] Advantageously, in the case where the fixing of each support 37 against the first wall 9a of the chest 9 is implemented by screwing or riveting, the first wall 9a of the chest 9 includes a screwing or riveting hole, not shown.

[0235] Here, each support 37 can be fixed against the first wall 9a of the chest 9 either by means of the fixing element 38 by gluing, or by means of the fixing element by screwing or riveting, or by means of the fixing element 38 by gluing and the fixing element by screwing or riveting.

[0236] Here, the fixing element 38 by bonding is an adhesive, in particular a double-sided adhesive.

[0237] In the case where the fixing element 38 by bonding is an adhesive, it has a cover, not shown, which is to be removed when the first surface 41a of the first arm 41 of one of the supports 37 is placed against the inner surface 9ai of the first wall 9a of the box 9. Following the removal of the cover, the second surface 42a of the second arm 42 of the support 37 is positioned against the outer surface 24e of the battery 24 and then the first surface 41a of the first arm 41 of the support 37 is pressed against the inner surface 9ai of the first wall 9a of the box 9.

[0238] In the case where the fixing of each support 37 against the first wall 9a of the chest 9 is implemented, on the one hand, by gluing, by means of an adhesive, and, on the other hand, by screwing or riveting, the adhesive is pierced beforehand by means of a tool or during the insertion of the screw or rivet, through the through hole 46 of the first arm 41 of the support 37.

[0239] In the case where the fixing of each support 37 against the first wall 9a of the box 9 can be carried out either by gluing, or by screwing, or by riveting, an installer has the choice between the three possibilities.

[0240] Advantageously, the battery 24 is held in position, in other words is configured to be held in position, inside the box 9, by means of the supports 37, in a horizontal position, in other words in a position extending along the length L9 of the box 9, in particular in the assembled configuration of the blackout device 3.

[0241] Here, the horizontal position of battery 24 is understood to be parallel to the ground and to the axis of rotation X.

[0242] The mounting of the battery 24 inside the box 9 of this blackout device 3 is carried out by fixing each support 37 against the first inner surface 9ai of the first wall 9a of the box 9, by means of at least one fixing element 38, by gluing and / or by screwing or riveting, and, at the same time, by positioning the outer surface 24e of the battery 24, on the one hand, against the second surface 42a of the second arm 42 of each support 37 and, on the other hand, against the first inner surface 9ai of the first wall 9a and the second inner surface 9bi of the second wall 9b of the box 9.

[0243] Thanks to the present invention, the supports allow the battery to be mounted inside the trunk, while minimizing the number of operations to be carried out by an installer, minimizing the time of intervention of the installer and minimizing the cost of the installation of the blackout device, with a low cost of the supports.

[0244] In addition, each support allows the battery to be positioned as close as possible to one of the corners of the trunk, formed by the first and second walls connected together, so as to optimize the size of the electrical energy storage device inside the trunk and to move the battery away from the screen, when the latter is being wound or unwound around the winding tube inside the trunk.

Thus, the battery 24 can be recharged by means of the auxiliary battery, which forms an external power supply, particularly when the shading device 3 is located far from a wall outlet. Furthermore, the auxiliary battery can be used to recharge the battery of other electrical equipment, particularly portable devices, such as, for example, a telephone. portable or a laptop computer.
