Description

HITCH PROFILE FOR PASSING

AIR AND CEILING ASSEMBLY COMPRISING

Such a profile

TECHNICAL FIELD OF THE INVENTION

[001] The invention relates to the field of false ceilings, and in particular that of stretch ceilings.

[002] The invention relates more particularly to a section of a hanging canvas for the realization of a ceiling stretched in a room for air circulation within it.

[003] The air circulated may be from a ventilation system and / or air conditioning (heating, cooling, dehumidification, humidification).

STATE OF THE ART

[004] Achievements of false ceiling are known allowing the passage of air in the room to be treated. In particular, a false ceiling fixing system is known that makes it possible to space the suspended ceiling section profiles by means of brackets or spacers fixed at regular intervals and thus generating a peripheral space. For example, it can be cited the patent application FR2815112.

[005] The prior art systems or profiles do not, however, make it possible to precisely control the diffusion of air at the periphery of the room. They also do not allow to get rid of air intake grilles which are commonly used and which are detrimental to the aesthetics of the room.

[006] On the other hand, it is known from document FR 2 619 531 to provide a section of hooked canvas, whose central core is closed by a flexible blade passage and blocking a non-deformable harpoon d hanging from the canvas, different perforations on the flexible blade and on the wall opposite its wing attachment to the wall. These perforations are in the form of segments of a width smaller than those of screws allowing the fixing of the profile to the wall wall with a relatively small length, being further spaced from each other, do not allow easy circulation of air between the plenum and the room, especially as the The central core of the profile is almost completely closed by the flexible harpoon retaining blade of the fabric. [007] Also, the international application WO 02/06604 describes a hanging section of a fabric whose two opposite wings for fixing to the wall wall and hanging cloth, are provided with perforations allowing a circulation of air above the canvas, but whose central core is closed by a flexible blade passage and blocking a non-deformable harpoon of a fabric, which also closes the space between the wall wall and the fixing wall, preventing any air circulation between the plenum and the room separated from each other by the fabric.

[008] The invention aims to remedy these problems by providing a hooked profile for a simple and fast assembly of a ceiling assembly for the circulation of fresh air and / or treated within a room. [009] The invention also aims to provide a ceiling assembly for precisely controlling the diffusion of air on the periphery of the room.

The invention also aims at providing a ceiling assembly for evading any visible device, and in particular grids, while ensuring the circulation of air within the local concerned and what they are traffic related to air conditioning or ventilation of the premises concerned.

OBJECT OF THE INVENTION

For this purpose, and according to a first aspect, the invention provides a hanging section of a fabric for the production of a ceiling stretched in a room to be treated, the hanging section comprising at least two wings interconnected by a connecting wall, one of the wings being arranged to allow attachment of the hanging profile on a wall of the room to be treated, said section being characterized in that it comprises at least one opening passage arranged to allow the passage of air through said profile. According to another feature, a second wing of the profile is provided with a locking end of a harpoon of a fabric, the connecting wall and the hooked wing being arranged to define together an unclosed slot passage of air through the profile and delimited on the one hand by the locking end of the harpoon of the hooked wing, the profile having at least one passage opening arranged to allow the passage of air through said profile from or towards the slot.

Advantageously, on the other hand, the air passage slot is delimited by the wall or the wall of the profiled section.

The configuration of the profile according to the invention thus allows to define all along the wall, an open air passage slot between the plenum and the local, devoid of any blocking element or inconvenience of the passage of air, contrary to the aforementioned prior arts. The openings provided on the hooked wing and / or the connecting wall of the profile according to the invention, which may each represent an open area of several square centimeters (for example 4 cm ² ) being spaced apart by less than 1 cm from one another, can form for one meter of profile according to the invention, a cumulative open surface of several hundred square centimeters thus providing a possibility of maximized air circulation.

In addition, the openings are provided on the profile according to the invention on the hooked wing, which is inclined, and on the connecting wall which extends horizontally between the room and the plenum, which facilitates the circulation of air between the room and the plenum.

Advantageously, one of the wings, which constitutes a hooked wing of the fabric, converges in the direction of the wing for fixing the hooked profile or the wall on which the hooked profile is fixed. In a particular configuration, the hooked wing of the fabric is arranged to have an angle of inclination relative to the other wing less than 90 degrees, and preferably between 30 and 50 degrees.

Advantageously, the passage or openings is (are) provided (s) on the hooked wing of the fabric or on the connecting wall. It may also be provided, according to an alternative embodiment, that the hooked wing of the fabric and the connecting wall both comprise at least one passage opening. The advantage of such an arrangement of the hooked section (positioning of the passage openings on the hooked wing of the fabric and / or the connecting wall and convergence of the hooked section) is avoid that the opening opening on the upper slab is visible from the room when the stretch ceiling is in place. Advantageously, the hooked wing of the fabric is provided with a plate for supporting a partition wall.

Advantageously, the wings are arranged to define a slot communicating with the passage opening, said slot being delimited by the profile of the fastening wing on the wall or by the wall even when the hooked profile is fixed on said wall wall and the hung wing of the canvas.

Advantageously, the hooked section comprises a baffle formed in the slot and arranged to deflect the flow of air passing through the profile towards the passage opening or the slot as the air enters through the slot or through the passage opening. Ideally, the profile according to the invention is formed by the association of two separate parts and secured to one another, the first part forming a section of which one of the branches forms the fastening flange, the second part forming a section provided with a securing means to the first part and at least one hooking means of a fabric. In this case, the securing means is in the form of an internal groove for receiving the end of a branch of the first part of the profile, made in the thickness of the second section portion. .

Advantageously, one or the other embodiments of the profile according to the invention may be provided with at least one closure cover of an air passage opening. This or these covers are inserts that can be positioned on certain openings of the profile to limit the air circulation at this location, for example to protect a decorative element such as a work of art positioned at this location. the wall wall. The hooked section of the invention has the advantage as will be understood with the detailed description of non-limiting implementation examples:

- to jointly allow the blowing and the aspiration of air

to overcome the aerodynamic grids present in the systems of the prior art to control the diffusion of air into the room

- not to see what is above the peripheral slot

- to allow easy mounting of the stretch ceiling

- to allow the association with any ventilation or air conditioning equipment (heating, cooling, dehumidification, humidification). The invention also relates to a ceiling assembly for the circulation of air within a room to be treated, the ceiling assembly comprising at least one stretch ceiling defining with the upper slab of the room to be treated under which it is mounted a plenum, the stretched ceiling comprising at least one stretched canvas extending between the wall walls of the room to be treated 1 and fixed thereto by means of hanging profiles, at least one of the hanging profiles being a hooked profile as described above so as to allow the passage of air between the plenum and the room.

Advantageously, the wings of the hooked section are arranged to define a slot communicating with the passage opening and oriented so that the air flows at the outlet of the plenum along the wall wall on which said profile is fixed. The air blown along the vertical walls with a hanging profile allowing the passage of air will indeed temper the walls thus reducing the temperature difference between these walls and the ambient air.

Advantageously, the plenum has a first and a second space separated by a partition wall, one of the spaces defining a plenum space for the air inlet into the room, the other space defining a space of plenum for the air outlet of the room.

Advantageously, the ceiling assembly comprises a plenum delimited by a stretched ceiling mounted in a room next to the room to be treated and the upper slab of the adjoining room, said plenum being separated from the plenum of the room to be treated by a partition through by at least one conduit allowing fluid communication between the two plenums.

Advantageously, the ceiling assembly is equipped with a ventilation system and / or air conditioning connected (s) fluidically, at least at the entrance to the plenum of the room to be treated. Advantageously, the air conditioning system is housed in the plenum of the adjoining room.

The ceiling assembly and the hanging profiles according to the invention provide the possibility of implementing, in a first configuration, the blowing and the suction of air within the same premises, and therefore in the same volume and, in a second configuration, the air blowing within the room to be treated (ventilation and or air conditioning) and the air intake in a common room.

In the case where the blowing and the air intake are implemented within the same premises, the plenum between the high slab and the stretched ceiling will be separated advantageously into two separate volumes and sealed one screw to screw of the other. This separation can be carried out in two ways: either by means of a "classical" separation profile based on a vertical separation wall, the stretched ceiling will then be provided with a "separator" at the right of the separation profile, or by means of a special profile of the hanging section (profile with plate allowing the attachment of a vertical separation wall, in which case it will not be necessary to install a separator on the stretched ceiling. The ceiling assembly and the hooked sections according to the invention thus allow the following three cases to be dealt with:

- air-conditioned and / or ventilated premises with air intake in a neighboring room,

- Air-conditioned and / or ventilated room with air supply and blow in the same room and implementation of a separator at the level of the stretched ceiling.

- air-conditioned and ventilated room with air supply and air intake in the same room and use of the special suction profile.

The ceiling assembly thus produced with the fastening profiles according to the invention makes it possible to completely do without blowing grilles or air suction so that the aesthetics of the local is improved.

Furthermore, when using a heating or air conditioning system, part of the power will be transmitted by radiation (hot or cold) from the ceiling, the rest by the circulation of air blown by means of the profiles (periphery of the room), thus generating excellent thermal comfort for the occupants.

DETAILED DESCRIPTION OF THE FIGURES

Figure 1 illustrates a schematic view of a ceiling assembly for the circulation of air within a room to be treated 1. By "room to be treated" means a room for receiving fresh air or to be treated according to the system implemented (ventilation system as illustrated in Figure 1 or air conditioning system).

In the illustrated embodiment, the ceiling assembly implements inside the room to be treated 1 a stretched ceiling (or false ceiling) formed of a stretched fabric 3 extending between the wall walls 4a, 4b of the room to be treated 1 and fixed thereto via hanging profiles and delimiting, with the upper slab 8, a plenum 14 and a plenum 16 separated in a sealed manner by a wall 11 provided with a profile of separation 27.

In order to allow the circulation of air in the room, two of the walls of the room are provided with hooked profiles arranged to allow the passage of air between the plenums 14 and 16 and the room to be treated 1 Depending on whether they allow the passage of the fresh air blown or the passage of the sucked air, it will be referred to as a blowing section 6a and a suction section 6b. These profiles are however identical. Examples of blow / suction profiles will be described later.

As illustrated in Figure 1, the suction profiles 6b are fixed on the walls located opposite the walls with the blowing profiles 6a. This has the advantage of obtaining an optimal air sweep of the room to be treated 1. The ceiling assembly further comprises a vertical partition wall 11 disposed in the plenum 14 to define two spaces, one of the spaces defining a plenum space for the air inlet into the room, the another space defining a plenum space for the air outlet of the room. Subsequently, it will be referred to as a blowing plenum 14 in which the fresh air is received and as a suction plenum 16 in which the air sucked from the room to be treated 1 is received.

In order to ensure a tight separation between the two spaces, the partition wall 11 is made integral in the lower part with a separation profile 27 taking up the stretched ceiling as shown in FIG. 1. Such a separation profile is known. in itself.

The blowing plenum 14 is equipped with a ventilation duct air fresh air 17 passing through the wall of the portion of the upper slab 8 defining the plenum blowing. Similarly, the suction plenum 16 is equipped with an air suction duct 18 passing through the portion of the upper slab delimiting the plenum suction.

FIG. 2 shows an exemplary embodiment of a blowing and suction profile 6a, 6b allowing the passage of air between the room to be treated 1 and the plenums 14 and 16 associated and implemented in the ceiling assembly of Figure 1.

The blowing and suction profile 6a, 6b comprises a first vertical flange 60 and a second flange 61 interconnected by a horizontal connecting wall 62.

The first wing defines a fastening flange 60 for fixing the profile on the wall wall. To do this, the fastening wing has holes 21 for the passage of fastening means such as screws, rivets or the like. In the illustrated embodiment, the fastening flange 60 extends from and above the connecting wall (i.e. upwardly). It is extended in the lower part by a third vertical wing 63.

The second wing defines for its part a hung wing 61 allowing the hang of the canvas. The hung wing converges towards the third wing. Advantageously, the hooked wing has an angle of inclination relative to the third wing at an angle of between 30 and 50 degrees, and 45 degrees of presence. According to FIG. 2, this hinged wing 61 carries on its inner wall directed towards the wall wall, a hooking means 30 for a harpoon 50 of a cloth, configured to dispose the harpoon of the cloth at a distance from the wall wall that runs along to define a passage slot for air. The hooking means 30 thus has the harpoon of the cloth along the lower edge of the hooked wall 61, leaving between the harpoon and the wall wall (or the third vertical wing 63) an air passage slot. . For example, the distance separating the hooked end of the means 30 may be between 0.5 and 5 cm, preferably between 1, 5 and 3 cm and more preferably of the order of 2 cm. . Ideally, as for the examples shown, the harpoon of the fabric may be provided elastically deformable, and the hook means 30, be in the form of a C-shaped hook in cross section curved towards the inner wall of the hook wall 61 so as to form with this inner wall, a passage groove for the elastically deformed harpoon, leading to a harpoon receiving groove in its undistorted configuration and a harpoon locking flange received in the throat and kept at a distance from the wall wall 4a by the hooked wall 61 in order to allow the air to pass. Thus, as shown, the hinged wing defines with the third wing a slot 22 having a passage opening 22a having an opening axis substantially parallel to the fixing flange to the wall wall. This thus ensures air supply at the entrance of the room along the wall wall on which the blower profile is fixed and at the outlet of the room (and therefore at the entrance of the plenum) an air intake having a trajectory substantially tangential to the wall wall carrying the suction profile. The slot allows, with the openings in the wing hooked, the passage of air between the plenum and the room.

The blowing and suction section 6a, 6b has passage openings 19 for the passage of air between the plenum and the room. In the illustrated embodiment, the openings are rectangular windows aligned along the hung wing. This is of course an example embodiment, the openings being able to present another form and / or be arranged differently. Moreover, the number of opening is variable and it can be provided a single opening or several openings. There may also be no opening the thus configured profile then becoming a "traditional" profile 7 hanging from the stretched ceiling. Advantageously, the hooked profiles 6a, 6b exist in different calibers, these gauges to provide different widths of the slot 22 located in the lower part of the profile and therefore different sections of the opening 22a. The use of airfoils thus calibrated makes it possible to perfectly control the air velocity blown on the periphery of the walls equipped with these sections. The air speed is calculated as a function of the blown air flow, it is determined so as to obtain a sufficient range of the blown air flow to reach the bottom of the vertical wall while respecting air velocities perceived by the occupants of the local very low and therefore optimal comfort. In the same way, the use of suction profiles thus calibrated makes it possible to control the suction speed so as to ensure an optimal air sweep. Advantageously, the blowing and suction section 6a, 6b comprises a deflector 23 (FIG. 8) for deflecting the flow of air towards the passage openings or the passage slot depending on whether the air enters through the slit of passage or through the openings of passage. The presence of a deflector has the advantage of improving the passage of air by minimizing the resistance of passage to the air and therefore the airflow losses of the profiles. In the embodiment illustrated in Figure 8, the baffle connects the connecting wall to the third wing. The deflector may be of any shape (rectilinear, curve, etc.), the optimum shape, however, respecting an arc of circle as shown in FIG.

The fresh air is blown into the plenum of blowing via the blowing duct passing through the upper slab, into the plenum of blowing to pass through the blowing section. At the outlet of the blow profile, because of the orientation of the slot 22, the fresh air runs along the wall wall equipped with the profile.

The air sucked as for him is driven to the ceiling stretched along a substantially tangential path to the wall wall provided with the suction section to cross the suction section. The sucked air is then extracted from the supply plenum via the extraction duct.

The adjoining room 2 is shown equipped with a stretch ceiling. It is of course obvious that it could not be equipped with a ceiling, the adjoining room not being used for the purposes of air circulation in the room to be treated, as is the other hand. case with the ceiling assemblies illustrated in Figures 3 to 7, 11 and 12.

FIG. 3 represents a particular embodiment in which the fresh air is blown into the room to be treated 1 and the air suction is carried out in a adjoining room 2.

The room to be treated 1 is equipped with a stretch ceiling 3 delimiting with the upper slab a plenum. The stretched ceiling is hooked to the wall walls 4a, 4b of the room via fastening profiles. In the illustrated embodiment, only one of the wall walls, the farthest in the example (wall 4a), is equipped with a profile allowing the passage of air, the remaining walls being equipped with hooked profiles. conventional (ie not being arranged to let air), these profiles 7 can also be achieved by means of profiles 6a / 6b not having openings 19 for air passage on the wing 61. In the illustrated example, the profile is a blowing section 6a.

Similarly, the adjoining room 2 is equipped with a stretch ceiling 5 delimiting a plenum with the upper slab a plenum 15. The stretched ceiling being attached to the walls of the adjoining room via hanging profiles, one at least the attachment profiles being a suction section 6b. If all the walls are not equipped with suction profiles 6b, the remaining walls can be equipped with conventional profiles 7 hanging from a stretch ceiling. In the example shown, only a wall, here the farthest from the room to be treated (wall 4c), is provided with suction profiles.

The plenum 14 of the room to be treated 1 forms the plenum of blowing while the plenum 15 of the adjoining room 2 forms the plenum suction.

In the illustrated embodiment, the sucked air passes between the volume of the treated premises 1 and the volume of the adjoining room 2 via an existing sealing or created for this purpose between the two premises, for example a relief under the door 4 separating the 2 premises. The sucked air then joins the plenum 15 through the peripheral suction slot 22 generated by the introduction of suction sections 6b.

The sucked air will then be extracted from the plenum of the adjoining room via an air duct 18 passing through the upper slab from the plenum of the adjoining room. Figure 4 shows another embodiment in which the circulating air is treated air from an air conditioning equipment 12 located in the adjoining room of the room to be treated 1.

The ceiling assembly resumes the arrangement of the ceiling assembly of Figure 3 in which the fresh air intake ducts and air extraction are replaced respectively by a ventilation duct 9 connected at the output of the air conditioning equipment and a suction air duct 10 connected to the input of the air conditioning equipment, the blowing duct passing through the wall separating the plenum of the room to be treated and the plenum of the adjoining room. As before, the plenum of the room to be treated forms the plenum of blowing while the plenum of the adjoining room forms the plenum of aspiration.

The treated air is blown into the plenum of the room to be treated by the air conditioning equipment via the blowing duct which passes through the blowing section to follow the wall wall equipped with the profile. The sucked air transits between the volume of the treated room 1 and the volume of the adjoining room 2 via an imperviousness between the two premises. The sucked air then joins the plenum 15 of the adjoining room by the peripheral suction slot 22 generated by the suction section 6 where it joins the air conditioning equipment via the suction air duct 10.

In some cases, however, it is not possible to generate sufficient sealing between the room to be treated 1 and a neighboring room 2 to convey the flow of air sucked. This may be the case, for example, premises having to provide sound insulation. The ceiling assembly illustrated in FIG. 5 makes it possible to overcome this constraint. The ceiling assembly used has an arrangement similar to the ceiling assembly of FIG. 1. It furthermore comprises a suction air duct 15 passing through the partition separating the suction plenum from the room to be treated and the plenum. of the adjoining room in which the air conditioning equipment is installed as well as a ventilation air duct 9 passing through the partition separating the two rooms and the partition wall 11 separating the plenum of suction and the plenum of the room to be treated. In this case, the adjoining room is equipped with a stretched ceiling 5 attached to the walls of the adjoining room via conventional hooked profiles 7 (ie not being arranged to let air).

As in the ceiling assembly of Figure 1, the suction air reaches the suction plenum 16 by the peripheral suction slot 22 generated by the establishment of the associated suction section 6. The sucked air then joins the recovery of any air-conditioning machinery by means of the suction air duct 10. The treated air is then recirculated via the blowing duct 9.

It can also be provided for the connection of the suction air ducts 10 and blowing 9 respectively to an exhaust air duct / outlet 18 and an air inlet duct 17 fresh air communicating with the outside the adjoining room and associated plenum (Figure 6) so as to achieve both the air conditioning and both the ventilation of the room to be treated 1.

The ceiling assembly thus produced thus makes it possible to treat a very tight room (for acoustic reasons for example) with respect to its adjoining premises 2.

Figure 9 illustrates an alternative embodiment of the hanging section according to the invention. In this variant, the hook profile 24 has the same shape as the profile of FIG. 2 except that it further comprises a horizontal plate 25 extending under the passage openings, in a direction opposite to the third wing. The plate serves to support a vertical partition wall without having to resort to the establishment of a visible separator on the stretched ceiling, as shown in Figures 10 to 12. This thus improves the aesthetic appearance the ceiling stretched while ensuring the circulation of air within the room.

As illustrated in Figures 10 to 12, the suction profiles 24 are fixed on the walls located opposite the walls with the blowing profiles. This has the advantage of obtaining an optimal air sweep of the room to be treated 1. The plate 25 may be advantageously provided with a lift to its end or any subjection for the attachment of the vertical partition wall.

Advantageously, the blowing and suction profiles and 6a, 6b, 24 may be provided with a grill disposed at the openings 19 so as to cover them. The presence of a fence thus prevents any impurity or insect can access the plenum 14, 15, 16) located between the high slab and the stretched ceiling. By way of example, the suction and blowing section 24 has been illustrated with such a filter 26 (FIG. 13).

According to a particular embodiment, it can be provided that the profiles for the suction 6b, 24 are provided with a filter. This filter can then replace the filters present in the ventilation and air conditioning machinery connected to the system. Advantageously, the filter is removable to allow its replacement or cleaning. FIG. 14 shows a possibility of integrating such a filter into a suction profile of the type of that of the section 24. In the embodiment illustrated, the filter 28 is held against the inside face of the wing of hung 61, placed on the edge 20b delimiting the hook groove 20 of the fabric, and is retained by a longitudinal tongue 28 carried by the inner face of the connecting wall 62. By "inner face" means the faces oriented towards the slot 22.

It is of course obvious that the hooked profiles are not limited to those previously described and that it can be provided other configuration without departing from the invention. In particular, it can be provided a section not having a third wing. In this case, the slot will be delimited by the hanging wing of the fabric and the wall on which the profile is fixed. Similarly it can be expected that the third wing is the fixing wing. Similarly, in the embodiments described above, the passage openings 19 are carried by the hooked wing 61 of the fabric. It may be provided, according to an alternative embodiment, that the passage openings 19 are formed not in the hooked wing, but in the connecting wall 62. By way of example, the profile of FIG. illustrated with such a positioning of the passage openings 19 (Figure 15). The ceiling assembly is compatible with any air conditioning and or ventilation technology. The air conditioning and / or ventilation equipment may be arranged in the plenum 14 located above the room 1 to be treated, in the plenum 15 of any premises adjoining the local 1 to be treated but also to any other place in the building. In general terms, it will be preferable to set up the equipment outside the volume of the room to be treated 1 so that it does not suffer any acoustic nuisance related to the operation of the machinery.

Regardless of the possibilities of air conditioning and or ventilation of the room, the invention allows the implementation of any type of stretch ceiling (conventional, acoustic ...) and allows the use of any process compatible with stretch ceilings, for example, backlighting, sound broadcasting systems, etc. In addition, a LED strip system could be installed at the angle between the flange 61 and the connecting wall 62 thus generating a peripheral illumination of the room without the LED strip being visible.

In general, within the room to be treated at least one wall will be equipped with a blower profile. It will be possible to choose the walls equipped with blowing profiles 6 and thus to choose the walls along which the treated air and the fresh air are blown. The other walls can be equipped with conventional profiles 7 hanging from the stretch ceiling. This choice makes it possible to optimize the thermal comfort of the room. In particular, it will be chosen for example to blow along the outer walls of the room, these walls being generally colder than the ambient air in winter and warmer than the ambient air in summer.

FIG. 16 illustrates another variant embodiment of a ceiling assembly, the latter comprising luminous means 40 fixed on the upper slab 8.

The illustrated ceiling assembly has a stretched ceiling formed of two stretched canvas 3a, 3b extending between the wall walls 4a, 4b of the room to be treated. Said webs 3a, 3b, arranged parallel to one another, are fixed to the wall walls by means of two hanging profiles 32, 34, one constituting a blowing section 32, the other constituting a suction section 34. An enlarged view of the blow profile 32 is illustrated in FIG. 17. As in the embodiments of hooked profiles previously described, the blowing section 32 comprises a fastening flange 60 connected to the hinged wing 61 of cloths by a connecting wall 62. As illustrated in FIG. 17, said flanges 60, 61 are arranged so that, when the blast section 32 is fixed to the wall wall 4a, the hooking flange 61 is inclined with respect to the connecting wall by converging towards the the wall wall 4a. The hooked wing 61 has two hanging grooves 20a, 20b of said webs 3a, 3b. One of the grooves is provided in the upper part of the hinged wing 61 with an opening on the inside of the profile, the other groove being formed in the lower part of the hinged wing 61. The passage openings 19 for the passage of air between the plenum 14 located above the upper stretched fabric 3b is carried by the connecting wall 62.

The blowing section 32 further comprises a vertical flange 64 extending from the connecting wall 62, parallel to the fixing flange 60, in a direction opposite to the hinged wing 61. In the embodiment of FIG. illustrated embodiment, the vertical flange 64 is provided at the end of the connecting wall 62. This vertical flange 64 serves to prevent the diffusion of light from the light means 40 via the passage openings 19 and the slot 22 of passage. We will speak later blocking wing 64 (or wing forming screen).

In order to avoid any shadow on the canvases, the ceiling assembly advantageously comprises a profile 36 of substantially V-shaped section fixed on the upper slab 8 of the room, in the vicinity of the hooked section 32, as shown in FIG. Figure 16. More particularly, the profile 36 is disposed relative to the hooked section 32 so as to leave sufficient space between the locking flange 64 and the profile 36 to allow the passage of air from the duct aeraulic blowing 17 fresh air.

In the illustrated embodiment, the hooked section 32 and the section 36 are two separate and independent parts of each other. These two profiles may however, according to an alternative embodiment, constitute a single piece. In this case, the locking wing 64 would also include, as the connecting wall 62, passage openings to allow the flow of air. The suction profile 34 meanwhile has all the characteristics of the blower profile 32, except that unlike the latter, it is devoid of locking flange. The diffusion of light is indeed blocked, in the ceiling assembly illustrated in Figure 16, by the partition wall 11 of the plenum 14 and suction plenum 16 of the room. It is of course obvious that it can also be provided a suction section 34 identical to the blowing section 42 without departing from the scope of the invention.

In addition to or in replacement of the light means 40 formed in the plenum 14 of the ceiling assembly, it is possible to provide luminous means fixed at the top of the hooked section according to the invention, preferably on the face the locking flange 64 facing the wall wall 4a, 4b so as to obtain illumination at the periphery of the room or the frame. In this case, it will be preferred to provide suction profiles 34 with locking wings 64.

According to a particular embodiment not illustrated, it may also be provided to position near the passage openings 19 a speaker or other equipment for the dissemination of sound to ensure efficient transmission of sound.

According to another advantageous embodiment, shown in Figures 18 and 19, the blowing and suction section 6a, 6b may be in the form of two independent parts 70, 71 to be fixed to one the other.

In the example shown, the first section portion 70 constitutes the fixing wing 60 and partially the horizontal connecting wall 62, and the second section portion 71 constitutes the remaining portion of the horizontal connecting wall 62 and the sloping hooked wing 61. [0091] The first section portion 70 is defined in a particularly simple form: that of an L-shaped section longitudinal section whose vertical branch constitutes the fixing wing 60 and the horizontal branch 73 constitutes a portion of the horizontal connecting wall 62. For the needs of air circulation, the horizontal branch of the L-shaped section will be provided with an air passage opening 19.

The second section portion 71 is slightly more complex and has the general shape of a trapezoidal cross-sectional longitudinal profile, whose long base 74, the short base 77 and the lateral side interposed between those 75 form the inclined hanging wing 61, the opposite lateral side 76 which is horizontal, forming the remaining part of the horizontal connecting wall 62.

More precisely, as can be seen in FIG. 18, the second profile portion has a longitudinal groove 78 for receiving the end of the horizontal branch 73 of the L of the first profile portion 70. A reported locking means , such as a screw, may be provided to engage an orifice 79 formed on the upper surface of the end of the horizontal leg L to block it, passing through the thickness of the upper lateral side of the second section of profile. A mark 80 may be provided on the outer surface of the upper lateral side 76 of the second profile portion to properly position the screw or other locking means facing the orifice 79 prior to its insertion into it.

This second section portion 71 comprises on the outer surface of its lateral side 75 which is vertical, the hook 30 above allowing the passage in a deformed configuration and blocking in a configuration at rest of an elastically deformable harpoon 50 hanging from a main stretched canvas 3a.

Advantageously, this second section portion 71, may comprise a second means of hanging an elastically deformable harpoon of a secondary stretched canvas 3b, as shown in Figure 18. This second means of hanging 81 is for example provided in the form of a longitudinal groove partially closed by at least one flange (two in the figure) retaining the harpoon of the second fabric, formed from the outer surface of the long base 74 of this second part profile, for example immediately below the groove 78 home the end of the first section portion.

This second fabric 3b can fulfill the function of collection and retention of deposits caused by dust and / or insects so that they remain at a distance from the underlying main fabric and can not be visible from the room through it when it is for example planned translucent.

The second section portion may further comprise different recesses 82 (marked in Figure 19) disposed in the thickness of the second section portion between the two harpoon locking grooves to serve as housing for brackets or fasteners 83 of functional elements disposed in the plenum, or simply to lighten the structure of the second section portion 70 to optimize the cost. Pins 86 may be provided projecting on the wall forming these recesses to partition their space and accommodate several brackets or block them in their respective recesses.

At the end of the second section portion 71, forming the junction between the horizontal upper side and the long inclined base, can be provided an inclined groove made in the thickness of the second section portion parallel to the surface external, to serve as a support and attachment for a locking wing or "wing screen" as presented above.

For the needs of air circulation, air passage openings 19 may be provided in this second profile portion on the constituent walls of the small and the large base in communication with each other. These openings, like those of the first section portion, may be closed if necessary by caches provided for this purpose and illustrated in Figures 20, 21.

These covers 90 may have the shape of parallelepipedal blocks, an upper face is provided with a lateral flange 91 intended to be applied against the contour of the opening 19 that the cover in question closes, and a lower face is provided with elastically deformable blades 92 is erased on passage of the opening and jamming behind the outline that defines it. In the example shown, the elastic blades extend along the lengths of the lateral sides of the parallelepiped block, with the exception of the angles thereof. Visual cues 88 in the form of extra thickness or longitudinal beads may be provided on the outer surfaces of each profile portion 70, 71 to easily and precisely connect two butt profiles parts if necessary. The constitution of the suction or blowing section in two parts thus defined is particularly clever because the second part 71 more complex can be performed in large series with a single dimension, while the first part 70 of extreme simplicity can be made with different dimensions, especially regarding the length of the branch of the L to be fixed to the second section portion to adjust as needed, by a simple choice of L-shaped profile available, the desired spacing between the wall wall and the edge of the canvas and thus the size of the slit and the air flow.

Thus, the L-shaped section of Figure 19 comprises a longer horizontal branch which has the edge of the main sheet 3 at a longer distance from the wall wall 4a than is the edge of the main sheet 3 in the variant of the embodiment of Figure 18 where the horizontal branch of the L-shaped section is shorter.

[00106] FIG. 22 represents an alternative embodiment of the blowing and suction section 6a, 6b of FIG. 19. In this variant, the second section portion 71 has the characteristics of that illustrated in FIGS. 18 and 19. On the other hand, the first profile portion 70 has no longer an L-shaped section, but a right-angle Z-shaped section. More specifically, the first section portion 70 consists of two horizontal branches connected to each other by a vertical branch, said horizontal branches extending in the opposite direction from one another. The upper horizontal branch, referenced 60, constitutes the fixing wing. It is fixed to the wall wall 4a via a bracket strip 60b. The lower horizontal leg, referenced 73, constitutes a portion of the horizontal connecting wall 62. In order to allow the flow of air, the vertical connecting branch, numbered 60a, is provided with an air passage opening 19. previously, the opening (s) provided (s) on the first portion of the section 70, such as those of the second section of profile 71, may be closed if necessary by covers as described above. The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
