Description

Title of the invention: Concealment device

[0001] The present invention relates to a concealment device comprising a screen driven in movement by an electromechanical actuator.

[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 position and at least a second position and, optionally, between at least a third and at least a fourth position.

[0003] And, more particularly, the present invention relates to the field of occultation devices comprising at least one screen, a first movable bar, a second movable bar and a motorized drive device. In an assembled configuration of the occultation device, the first movable bar is disposed between an upper portion of a window or door and the second movable bar. The second movable bar is disposed between the first movable bar and a lower portion of the window or door. The screen is disposed between the first and second movable bars. The screen is configured to be driven into movement by the motorized drive device.The motorized drive device sets in motion, on the one hand, the first movable bar connected to the screen, between at least a first position and at least a second position, and, on the other hand, the second movable bar connected to the screen, between at least a third position and at least a fourth position.

[0004] A motorized drive device comprises an electromechanical actuator of a mobile occultation or solar protection element, such as a blind or any other equivalent material, hereinafter called a screen.

[0005] Document WO 2021 / 209430 A1 is already known, which describes a screening device comprising a housing, a screen, a drive shaft, a movable bar, a motorized drive device, a battery, and four supports. The screen comprises a first end and a second end, the second end being opposite the first end. The first end of the screen is connected to the movable bar. The motorized drive device is configured to move the screen. Each support comprises a lower side, an upper side, and two lateral sides. Each support is mounted inside the housing. Each support comprises a clearance. The clearance is configured to receive the drive shaft. The motorized drive device comprises an electromechanical actuator and a power supply cable.The electromechanical actuator is configured to rotate the drive shaft, so as to drive the movable bar in movement. The electromechanical actuator is mounted inside the . housing. The power supply cable supplies electrical power to the electromechanical actuator from the battery, which is a power supply source. In addition, each of the supports includes two openings. Each of these openings is configured to allow the power supply cable to pass through, electrically connecting the battery to the electromechanical actuator. This concealment device is generally satisfactory.

[0006] However, this concealment device has the disadvantage of fixing each of the supports either on the electromechanical actuator or on the battery, so as to assemble the electromechanical actuator and the battery inside the housing.

[0007] Thus, each of the supports is not arranged between the electrical power supply source and the electromechanical actuator to guide the electrical power cable inside the housing at a certain distance from the electrical power supply source and the electromechanical actuator, since the supports are either supported against the electromechanical actuator or supported against the battery.

[0008] In this way, each of the supports only makes it possible to avoid contact between the electrical power supply cable and the drive shaft at one of the two ends of the electromechanical actuator or the battery, but not at an internal area of ​​the housing remote from the electromechanical actuator and the battery.

[0009] Therefore, the power supply cable may contact the drive shaft at an area internal to the housing remote from the electromechanical actuator and the battery, which may cause damage to the insulation sheath of the power supply cable.

[0010] The present invention aims to solve the aforementioned drawbacks and to propose a concealment device comprising at least one support mounted inside a housing making it possible to hold an electrical power supply cable in position inside the housing over the entire distance between an electrical power supply source and an electromechanical actuator, so as to avoid contact between the electrical power supply cable and at least one drive shaft and, consequently, so as to avoid damaging an insulating sheath of the electrical power supply cable.

Advantageously, the electromechanical actuator 11 further comprises at least a first universal joint and a second universal joint.The coupling device 33 is assembled, in particular in the assembled configuration of the electromechanical actuator 11, with the connecting shaft by means of the first universal joint. Furthermore, the second clutch 23b is assembled, in particular in the assembled configuration of the electromechanical actuator 11, with the connecting shaft by means of the second universal joint. Thus, the first and second universal joints make it possible to ensure torque transmission between the coupling device 33 and the second clutch 23b via the connecting shaft, while accommodating positioning dispersions between the output shaft of the coupling device 33 and the input shaft 25 of the second clutch 23b.Advantageously, along the second axis of rotation Xb, at least a portion of the control unit 15 is arranged between the coupling device 33 and the second clutch 23b, in particular in the assembled configuration of the electromechanical actuator 11. Furthermore, the connecting shaft extends, along the second axis of rotation Xb, through a zone of the electromechanical actuator 11 comprising the control unit 15. This zone of the electromechanical actuator 11 is defined, along the second axis of rotation Xb, between the coupling device 33 and the second clutch 23b.

[0249] A movement generated by the electric motor 16 is transmitted to the first drive shaft 9a, via the first clutch 23a, the first reduction gear 19a and the first coupling element 20a, if the first clutch 23a is in the engaged position. This same movement generated by the electric motor 16 is also transmitted to the second drive shaft 9b, via the coupling device 33, the second clutch 23b, the second reduction gear 19a and the second coupling element 20a, if the second clutch 23b is in the engaged position.

[0250] Thus the electromechanical actuator 11 makes it possible, using this single electric motor 16 and the control unit 15, to drive the screen 2 according to several pos- sibilities.

[0251] When the first and second clutches 23a, 23b are in the engaged position and the electric motor 16 is electrically activated, the movement generated by the electric motor 16 is transmitted to the first and second drive shafts 9a, 9b, which are then rotated respectively about the first and second axes of rotation Xa, Xb. In this case, the first and second movable bars 8a, 8b simultaneously perform the same vertical movement. This makes it possible to choose the position of a zone for concealing the opening.

[0252] When only the first clutch 23a is in the engaged position and the electric motor 16 is electrically activated, the movement generated by the electric motor 16 is transmitted only to the first drive shaft 9a. In this case, only the first movable bar 8a moves vertically, while the second movable bar 8b remains in position, in other words is stationary. Thus, it is the height of the occultation zone which is modified relative to the opening.

[0253] Similarly, when only the second clutch 23b is in the engaged position and the electric motor 16 is electrically activated, the movement generated by the electric motor 16 is transmitted only to the second drive shaft 9b. In this case, only the second movable bar 8b moves vertically, while the first movable bar 8a remains in position, in other words is stationary. Thus, it is the height of the occultation zone which is modified relative to the opening.

[0254] The first and second movable bars 8a, 8b can therefore be moved vertically by the electromechanical actuator 11 separately or simultaneously.

[0255] The occulting device 3 further comprises at least one support 40.

[0256] Here and as illustrated in [Fig.l], the occulting device 3 comprises two supports 40.

[0257] The number of supports is not limiting and may be different. It may be, for example, one or greater than or equal to three.

[0258] Advantageously, when the occulting device 3 comprises at least two supports 40, these are identical.

[0259] In the following, one of the supports 40 is described, it being specified that the description applies to any of the supports 40.

[0260] The support 40 belonging to the occultation device 3 illustrated in [Fig. 1] will now be described in more detail and with reference to FIGS. 3 to 5, according to the embodiment of the invention.

[0261] The support 40 comprises at least one lower side 40a, one upper side 40b and two lateral sides 40c.

[0262] The support 40 is mounted, in other words is configured to be housed, inside the housing 7, in particular in the assembled configuration of the occulting device 3.

[0263] Here, the support 40 is configured to adapt to a profile of the housing 7 and, more particularly, to a geometry of an internal face 7e of the housing 7, defined, in particular, by the lower wall 7a and the side walls 7b.

[0264] The support 40 comprises a clearance 41. Furthermore, the clearance 41 is configured to receive, in other words receives, in particular in the assembled configuration of the concealing device 3, at least one drive shaft 9a, 9b.

[0265] Here, the clearance 41 is configured to receive, in other words receives, the first and second drive shafts 9a, 9b.

[0266] Thus, the support 40 is designed to be traversed by the first and second drive shafts 9a, 9b. In other words, the first and second drive shafts 9a, 9b extend through the clearance 41 of the support 40.

[0267] In this way, the first and second drive shafts 9a, 9b can be rotated by the electromechanical actuator 11, respectively around the first and second axes of rotation Xa, Xb, through the clearance 41 of the support 40, while avoiding interference with them.

[0268] Advantageously, the clearance 41 of the support 40 comprises a mouth 41a. The mouth 41a is oriented, that is to say opens out, towards the lower side 40a of the support 40. Furthermore, the mouth 41a of the clearance 41 of the support 40 is configured to insert the first drive shaft 9a and, in the present case, the second drive shaft 9b towards the inside of the clearance 41 of the support 40, during the assembly of the concealing device 3.

[0269] Thus, the support 40 is designed to be arranged around the first and second drive shafts 9a, 9b by means of the mouth 41a of its clearance 4L

[0270] In this way, the support 40 spans the first and second drive shafts 9a, 9b.

[0271] The support 40 is independent of the electromechanical actuator 11 and is distant from the electrical energy supply source 29 and from the electromechanical actuator 11, in a longitudinal direction L of the housing 7.

[0272] By “remote” is meant that a distance measured parallel to the longitudinal direction L, between the support 40 and the electrical energy supply source 29 or between the support 40 and the electromechanical actuator 11, is several centimeters.

[0273] The support 40 comprises at least one notch 42.

[0274] Here, the support 40 comprises three notches 42.

[0275] The number of notches is not limiting and may be different. It may be, for example, one, two or greater than or equal to four.

[0276] The or each notch 42 extends from the upper side 40b of the support 40 towards the inside of the support 40.

[0277] Here, the or each of the notches 42 of the support 40 is a slot.

[0278] In addition, the or each notch 42 holds the power cable in position. electrical 37 inside the housing 7 between the electrical power supply source 29 and the electromechanical actuator 11, remotely from the first drive shaft 9a and, in this case, from the second drive shaft 9b.

[0279] Thus, the support 40 mounted inside the housing 7 makes it possible to hold the electrical power supply cable 37 in position inside the housing 7 over the entire distance D between the electrical power supply source 29 and the electromechanical actuator 11, so as to avoid contact between the electrical power supply cable 37 and the first and second drive shafts 9a, 9b and, consequently, so as to avoid damaging an insulating sheath of the electrical power supply cable 37.

[0280] In this way, the support 40 is an accessory for holding the electrical power supply cable 37 in position inside the housing 7, between the electrical power supply source 29 and the electromechanical actuator 11.

[0281] Furthermore, the or each of the notches 42 of the support 40 is configured to maintain, in other words keeps, out of reach the electrical power supply cable 37 relative to the first and second drive shafts 9a, 9b, in particular in the assembled configuration of the concealing device 3.

[0282] Advantageously, the support 40 is independent of the battery 24 and / or the transformer and is distant from the battery 24 and / or the transformer.

[0283] By “distant” is meant that a distance measured parallel to the longitudinal direction L, between the support 40 and the battery 24 or between the support 40 and the transformer, is several centimeters.

[0284] Here, the support 40 is freely assembled inside the housing 7 between the various other members mounted inside the housing 7. In other words, the support 40 is not fixed to the electromechanical actuator 11, nor to the battery 24, nor to the transformer, nor to one of the first, second, third and fourth drive arrangements 6a, 6b, 6c, 6d, while it guides the electrical power supply cable 37 inside the housing 7 between the electrical energy supply source 29 and the electromechanical actuator 11.

[0285] Advantageously, the holding in position of the electrical power supply cable 37 inside the housing 7 is implemented following a movement of the electrical power supply cable 37 from the outside of the housing 7 towards the inside of the, one or each of the notches 42 of the support 40.

[0286] Advantageously, the or each of the notches 42 of the support 40 is arranged, in other words is configured to be arranged, in particular in the configuration assembly of the occulting device 3, inside the housing 7. Furthermore, the power supply cable 37 is held inside one or more notches 42 of the support 40, following the movement of the power supply cable 37 from outside the housing 7 to inside the housing 7 by inserting it into one or more of the notches 42 of the support 40.

[0287] Thus, the support 40 makes it possible to prevent the electrical power supply cable 37 from being arranged at least partly outside the housing 7, while guaranteeing an aesthetic appearance of the concealment device 3.

[0288] In this way, the support 40 is housed inside the housing 7 without protruding outside of it, while maintaining the electrical power supply cable 37 inside the housing 7.

[0289] Advantageously, the support 40 comprises two fixing lugs 43, at the upper side 40b thereof. The housing 7 comprises a projecting portion 44 at each of its side walls 7b. Each projecting portion 44 of the side walls 7b of the housing 7 is oriented towards the inside of the housing 7. Furthermore, each fixing lug 43 of the support 40 cooperates, in other words is configured to cooperate, with the projecting portion 44 of one of the side walls 7b of the housing 7, so as to immobilize the support 40 inside the housing 7, in particular in the assembled configuration of the concealing device 3.

[0290] Here, the projecting portion 44 of each of the side walls 7b of the housing 7 is obtained by folding one end of one of the side walls 7b of the housing 7 towards the inside of the housing 7 and, more particularly, towards the lower wall 7a of the housing 7, so as to form a rib, which can also be called a strip.

[0291] As a variant, not shown, the projecting part 44 of each of the side walls 7b of the housing 7 is obtained by a deformation of another type of one of the side walls 7b of the housing 7 towards the inside of the housing 7, for example by stamping in the case where the housing 7 is made of metallic material.

[0292] Advantageously, the support 40 comprises at least one support tab 45, at the lower side 40a thereof.

[0293] Here, the support 40 comprises two support legs 45.

[0294] In addition, the or each support leg 45 of the support 40 is supported, in other words is configured to be supported against the lower wall 7a of the housing 7, so as to position the support 40 inside the housing 7, in particular in the assembled configuration of the concealment device 3.

[0295] Here, each of the two support tabs 45 is arranged at one of the lateral sides 7c of the support 40. Furthermore, the clearance 41 of the support 40 is provided between its two support tabs 45.

[0296] Thus, the clearance 41 of the support 40 is arranged in the central part thereof.

[0297] Here, the bearing tabs 45 of the support 40 are placed in abutment, in other words are configured to be placed in abutment, in particular in the assembled configuration of the concealing device 3, against the lower wall 7a of the housing 7. Furthermore, each fixing tab 43 of the support 40 is placed in abutment, in other words is configured to be placed in abutment, in particular in the assembled configuration of the concealing device 3, against the projecting part 44 of one of the side walls 7b of the housing 7.

[0298] Advantageously, each notch 42 of the support 40 is configured to hold in position, in other words keeps in position, a part of the electrical power supply cable 37, so as to adapt a length, called “apparent”, of the electrical power supply cable 37 as a function of the distance D between the electromechanical actuator 11 and the electrical energy supply source 29, in particular in the assembled configuration of the occultation device 3.

[0299] The apparent length of the electrical power cable 37 is the distance between its ends, when the electrical power cable 37 is in place inside the housing 7, in particular in the assembled configuration of the concealment device 3. As the electrical power cable 37 can make loops or coils inside the housing 7, this apparent length can be strictly less than the developed length of the electrical power cable 37, which is the distance between its ends when the electrical power cable 37 is stretched, in a straight configuration.

[0300] Thus, the notches 42 of the support 40 make it possible to store a surplus length of the electrical power supply cable 37, in particular by making coils 46, in other words undulations, loops or back-and-forths, with the electrical power supply cable 37 by means of the notches 42 of the support 40.

[0301] In this way, the notches 42 of the support 40 make it possible to avoid contact between the electrical power supply cable 37 and the first and second drive shafts 9a, 9b, when the electrical power supply cable 37 has a developed length greater than the distance D between the electrical power supply source 29 and the electromechanical actuator 11.

[0302] Therefore, the power supply cable 37 is held in position inside the housing 7 by means of the support 40 without risk of damaging an insulation sheath of the power supply cable 37.

[0303] Advantageously, the support 40 is made of a plastic material, which may be, for example, PolyOxyMethylene, with the acronym POM, PolyAmide 6, also called polycaprolactam, with the acronym PA 6, or PolyAmide 6.6, also called polyhexamethylene adipamide, with the acronym PA 6.6.

[0304] As a variant, not shown, in the case where the first communication module 27 is of the wireless type, in particular configured to receive and / or transmit radio signals, the first communication module 27 of the control unit 15 comprises an antenna formed by a cable. In addition, the, one or each of the notches 42 of the support 40 is, in addition, configured to maintain in position, in other words also maintains in position, the antenna inside the housing 7 at a distance from the first and second drive shafts 9a, 9b, in particular following a movement of the antenna from outside the housing 7 towards the inside of the, one or each notch 42 of the support 40.

[0305] As a variant, not shown, in the case where the motorized drive device 5 further comprises an additional module. The additional module comprises at least one sensor. The additional module is electrically connected to the electromechanical actuator 11 and, more particularly, to the control unit 15 by means of an additional signal transmission cable. Furthermore, the, one or each of the notches 42 of the support 40 is, furthermore, configured to hold in position, in other words also holds in position, the additional signal transmission cable inside the housing 7 at a distance from the first and second drive shafts 9a, 9b, in particular following a movement of the additional signal transmission cable from outside the housing 7 towards the inside of the, one or each notch 42 of the support 40.

[0306] By virtue of the present invention, the or each support mounted inside the housing makes it possible to hold the electrical power cable in position inside the housing over the entire distance between the electrical power supply source and the electromechanical actuator, so as to avoid contact of the electrical power cable with the drive shaft(s) and, consequently, so as to avoid damage to an insulation sheath of the electrical power cable.

[0307] Numerous modifications can be made to the embodiments described above without departing from the scope of the invention.

[0308] As a variant, not shown, the occultation device 3 comprises only one movable bar, namely either the first movable bar 8a or the second movable bar 8b.

[0309] As a variant, not shown, the occulting device 3 comprises a number of movable bars greater than or equal to three, which can all be moved by means of the electromechanical actuator 11, respectively by means of a reducer, a torque transmission device and, possibly, a clutch, a counting device and a brake.

[0310] Alternatively, not shown, the first and second cords 4a, 4b, as well as the third and fourth cords 4c, 4d, in particular their ends, are fixed to a window or door structure or to a wall of the building, in particular by means holding elements. Thus, the concealment device 3 may be without a housing, in other words a rail, arranged in the upper part or above the opening. In this case, the holding elements are configured to be fixed, in other words are fixed, to the window or door structure or to the wall of the building by means of fixing screws, not shown. The fixing screws pass through through holes provided in the holding elements and are screwed either into dowels, not shown, housed in the window or door structure or in the wall of the building or directly into the window or door structure or in the wall of the building.Furthermore, the length of the first, second, third and fourth cords 4a, 4b, 4c, 4d is provided so that these are permanently taut relative to the window or door structure or the wall of the building, so as to allow the movement of the first and second movable bars 8a, 8b along them. In this case, the motorized drive device 5, in particular the electromechanical actuator 11, is mounted, in other words is housed, inside one of the movable bars 8a, 8b, in particular in the assembled configuration of the occulting device 3.

[0311] In another variant, not shown, the first, second, third and fourth cords 4a, 4b, 4c, 4d can be kept taut by means of one or more elastic return elements, such as, for example, one or more springs.

[0312] In another variant, the first and second drive shafts 9a, 9b are coaxial. In this case, the first and second drive shafts 9a, 9b are located on either side of the electromechanical actuator 11. In other words, the first coupling element 20a is arranged at the first end 11a of the electromechanical actuator 11 and the second coupling element 20b is arranged at the first end 11b of the electromechanical actuator 11. Thus, the two outputs of the electromechanical actuator 11 are arranged on each side of the electromechanical actuator 11, in particular of the casing 17. Furthermore, the first and second drive shafts 9a, 9b are arranged on each side of the electromechanical actuator 11 like the first and second coupling elements 20a, 20b.

[0313] Alternatively, the electric motor 16 of the electromechanical actuator 11 may be of the asynchronous type.

[0314] Alternatively, not shown, the electromechanical actuator 11 further comprises at least one other electric motor. Thus, the electromechanical actuator 11 comprises the electric motor 16, which may be called the first electric motor, and a second electric motor, in particular identical. In this case, the electromechanical actuator 11 is devoid of a coupling device 33 and first and second clutches 23a, 23b. Thus, the first electric motor 16 is configured to rotate, i.e. rotates, the first coupling element 20a, via the first reducer 19a and the first torque transmission device 10a, and the second electric motor is configured to rotate, i.e. rotates, the second coupling element 20b, via the second reducer 19b and the second torque transmission device 10b. In this case, the first assembly 22 comprises the first electric motor 16, which is aligned along the first axis of rotation Xa, and the second assembly 26 comprises the second electric motor, which is aligned along the second axis of rotation Xb.

[0315] Regardless of the embodiment, one or each of the first, second, third and fourth cords 4a, 4b, 4c, 4d may be replaced by a chain.

[0316] Furthermore, the embodiments and variations contemplated may be combined to generate new embodiments of the invention, without departing from the scope of the invention.
