Description

Blackout device

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

In general, 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.

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 arranged between an upper portion of a window or a door and the second movable bar. The second movable bar is arranged between the first movable bar and a lower portion of the window or the door. The screen is arranged between the first and second movable bars. The screen is configured to be driven in 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.

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

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 drive the screen in movement. 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 energy to the electromechanical actuator from the battery constituting a source of electrical energy. In addition, each of the supports comprises two openings. Each of these openings is configured to allow the power supply cable electrically connecting the battery to the electromechanical actuator to pass through. This concealment device is generally satisfactory.

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.

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 either bear against the electromechanical actuator or bear against the battery.

In this way, each of the supports only prevents contact between the 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 distant from the electromechanical actuator and the battery.

As a result, the power supply cable may contact the drive shaft at an area inside the housing remote from the electromechanical actuator and battery, potentially causing damage to the power supply cable insulation sheath.

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 energy supply source and an electromechanical actuator, so as to avoid contact of the electrical power supply cable with at least one drive shaft and, consequently, so as to avoid damaging an insulation sheath of the electrical power supply cable.

A motion generated by the electric motor 16 is transmitted to the first drive shaft 9a, via the first clutch 23a, the first reducer 19a and the first coupling element 20a, if the first clutch 23a is in the engaged position. This same motion 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 reducer 19a and the second coupling element 20a, if the second clutch 23b is in the engaged position.

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 possibilities.

When the first and second clutches 23a, 23b are in the engaged position and the electric motor 16 is electrically activated, the motion 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 motion. This makes it possible to choose the position of a zone for obscuring the opening.

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, i.e. is stationary. Thus, it is the height of the occultation zone that is modified relative to the opening.

Similarly, when only the second clutch 23b is in the engaged position and the electric motor 16 is electrically activated, the motion 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, i.e. is stationary. Thus, it is the height of the occultation zone that is modified relative to the opening.

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

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.

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.

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 concealment device 3.

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 41.

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

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.

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.

The support 40 comprises at least one notch 42.

Here, the support 40 comprises three notches 42.

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

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

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

Furthermore, the or each notch 42 holds the electrical power supply cable 37 in position inside the housing 7 between the electrical energy supply source 29 and the electromechanical actuator 11, at a distance from the first drive shaft 9a and, in this case, from the second drive shaft 9b.

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 energy 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 insulation sheath of the electrical power supply cable 37.

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

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 concealment device 3.

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.

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.

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.

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.

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 assembled configuration of the concealment device 3, inside the housing 7. Furthermore, the electrical power supply cable 37 is held inside one or more notches 42 of the support 40, following the movement of the electrical power supply cable 37 from the outside of the housing 7 towards the inside of the housing 7 by inserting it into one or more of the notches 42 of the support 40.

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.

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

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 concealment device 3.

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.

Alternatively, not shown, the projecting portion 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 metal material.

Advantageously, the support 40 comprises at least one support tab 45, at the level of the lower side 40a thereof.

Here, the support 40 comprises two support legs 45.

Furthermore, the or each support tab 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.

Here, each of the two support legs 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 legs 45.

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

Here, the support 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 concealment 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 concealment device 3, against the projecting part 44 of one of the side walls 7b of the housing 7.

Advantageously, each notch 42 of the support 40 is configured to hold in position, in other words maintains in position, a portion 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.

The apparent length of the power supply cable 37 is the distance between its ends, when the power supply cable 37 is in place inside the housing 7, in particular in the assembled configuration of the concealment device 3. Since the power supply cable 37 can make loops or serpentines inside the housing 7, this apparent length can be strictly less than the developed length of the power supply cable 37, which is the distance between its ends when the power supply cable 37 is taut, in a straight configuration.

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 serpentines 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.

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 energy supply source 29 and the electromechanical actuator 11.

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.

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.

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 the outside of the housing 7 towards the inside of the, one or each notch 42 of the support 40.

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 energy 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 damaging an insulation sheath of the electrical power cable.

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 housing 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.
