Description

Title of the invention: Panel for suspended false ceiling, suspended false ceiling system and panel kit

[0001] The present invention relates to the technical field of suspended ceilings, and more particularly to a panel for a suspended false ceiling, a suspended false ceiling system and a kit for a panel.

[0002] Suspended false ceiling systems comprising panels suspended by means of support profiles at a certain distance below the ceiling of a building have been known for a long time and many solutions are proposed in the prior art.

[0003] European patent EP2458103 B1 discloses in particular a system of ceiling decoration panels in which panels composed of slats and counter-slats are suspended from carriers.

[0004] However, with existing systems, it is possible that in use an unintentional shock applied from below a panel may lift said panel which may then be mispositioned, or even fall.

[0005] Consequently, the prior art solutions proposed for suspended ceilings still have disadvantages and improvements are possible.

[0006] The present invention aims in particular to solve the problems indicated above by proposing a panel for a suspended false ceiling, a suspended false ceiling system and a kit for a panel.

[0007] Thus, the present invention relates to a rectangular panel for a suspended false ceiling, configured to be suspended from two parallel and coplanar flanges of two support profiles with cross-sections at least partially in the shape of an "L", the cross members of the "L"s forming said two flanges, the panel comprising: a suspension portion, configured to suspend the panel from said two flanges and comprising a first suspension side having a first support projection configured to, in a state of the panel suspended from said two flanges, bear on a first flange of said two flanges, and a second opposite suspension side having a second support projection configured to, in the state of the panel suspended from said two flanges, bear on a second flange of said two flanges, a distance, projected in a plane called the profile plane perpendicular to the first and second suspension sides,between a distal end of the first support projection and a distal end of the second support projection being greater than a spacing of said two soles, and a distance, in projection in the profile plane, between a proximal end of the first support projection and a proximal end of the second support projection being less than or equal to, at the spacing of said two footings, and the first support projection defining, in projection in the profile plane, an upper side of a first footing reception space, and the second support projection defining, in projection in the profile plane, an upper side of a second footing reception space, and the first footing reception space and the second footing reception space extending respectively from one of the lateral sides connecting the first and second suspension sides to the other of the lateral sides; a decorative part, attached to a lower portion of the suspension part and configured to be oriented towards the ground, the decorative part being set back from the second suspension side of the suspension part so as to form a clearance under the second suspension side,the clearance extending in depth along the direction of the second support projection and in width from one lateral side to the other lateral side, the distance, projected onto the profile plane, between a bottom of the clearance and the distal end of the first support projection being less than or equal to the spacing of said two flanges, and the clearance being configured to temporarily receive a distal end of the second flange during a panel mounting phase from below the support profiles; and a buttress face, formed on the first suspension side and configured to extend, projected onto the profile plane, from a proximal end of a lower face of the first support projection to a lower face of the panel, and the buttress face defining, projected onto the profile plane, a lateral side of the first flange receiving space; characterized in that the panel further comprises,on the second suspension side, an anti-uplift projection configured to extend parallel to the second support projection and to extend, in projection in the profile plane, between the second support projection and the clearance so as to define a lower side of the second footing receiving space, the anti-uplift projection extending such that, in projection in the profile plane, a distal end of the anti-uplift projection is set back from the distal end of the second support projection and a distance, in projection in the profile plane, between the proximal end of the first support projection and the distal end of the anti-uplift projection is greater than the spacing of said two footings, and the anti-uplift projection being configured so that, in the state of the panel suspended from said two footings, it is disposed under the second footing,such that the panel is configured to receive the second base plate between the second support projection and the anti-uplift projection by means of an elastic interlocking relationship between the anti-uplift projection and the second base plate.

[0008] This configuration in particular prevents, in use, an unintentional shock applied from the underside of the panel from lifting it, so that the panel does not fall or reposition itself incorrectly.

[0009] In particular, a force applied to the panel in a direction from the decorative part to the suspension part must exceed a predefined value to release the second support plate located between the second support projection and the anti-uplift projection in the second support plate's receiving space. Preferably, the predefined value is chosen to allow a user to remove the panel by hand.

[0010] The support profiles are preferably support profiles with cross sections in the shape of an inverted "T", support profiles with cross sections in the shape of an "L", or a combination of support profiles in the shape of an "L" and support profiles in the shape of an inverted "T".

[0011] The support profiles can for example be of type T24.

[0012] According to a particular embodiment, the lower portion of the suspension part is secured by attachment to at least one element of the decorative part or is formed in one piece with the decorative part.

[0013] The fixing can be achieved by any means, for example by screwing, by gluing, by nailing, or by a combination of these.

[0014] According to a particular embodiment, the lower face of the first support projection extends in the same plane as a lower face of the second support projection.

[0015] This configuration is particularly suitable for allowing, in use, an underside of the panel to be horizontal.

[0016] According to a particular embodiment, a distance, projected in the profile plane, between a lower end of the abutment face and the proximal end of the second support projection is greater than the spacing of said two soles.

[0017] With this configuration, if, in the state of the panel suspended from said two soles, a movement is applied to the panel in a direction from the decoration part towards the suspension part (vertical upward movement in use), at the level of the first suspension side, the stop face comes into contact with the first sole, so that the first sole does not come out of the first sole reception space.

[0018] According to a particular embodiment, the panel further comprises, on the first suspension side, a masking portion configured to extend parallel to the first support projection and to extend, in projection in the profile plane, from the abutment face so as to define a lower side of the first footing reception space, and a distance, in projection in the profile plane, between a distal end of the masking portion and proximal end of the second support projection being greater than the spacing of said two soles.

[0019] It will therefore be understood that if, in the state of the panel suspended from the said two soles, a movement is applied to the panel in a direction going from the decoration part towards the suspension part, at the level of the first suspension side, the masking portion comes to rest against the first sole, so that the first sole does not come out of the first sole reception space.

[0020] According to a particular embodiment, the masking portion extends beyond the first support projection, such that, in projection in the profile plane, the distal end of the first support projection is recessed relative to the distal end of the masking portion.

[0021] This configuration makes it possible in particular to hide a larger portion of the first sole.

[0022] According to a particular embodiment, in projection in the profile plane, a distance between the first support projection and the masking portion is greater than a distance between the second support projection and the anti-uplift projection.

[0023] This configuration allows, in particular, for two base plates to be slid into the receiving space of the first base plate, which may be necessary when installing a suspended false ceiling at a junction with a wall. Indeed, at the junction with a wall, it is generally necessary to accommodate a base plate of a support profile fixed to the wall, in addition to the first base plate of a support profile suspended from the ceiling.

[0024] According to a particular embodiment, the clearance is configured such that the panel further includes a guide face configured to extend, in projection in the profile plane, obliquely between the bottom of the clearance and the distal end of the anti-uplift projection, at an angle between 30 and 60 degrees, the guide face being configured to, during the panel assembly phase, guide the anti-uplift projection towards the second base, by gravity.

[0025] In projection in the profile plane, the guide face can for example extend obliquely at an angle of 40 degrees with respect to a horizontal axis, and therefore at an angle of 50 degrees with respect to a vertical axis.

[0026] The guide face is configured to guide the anti-uplift projection towards the second base plate by gravity during the panel mounting phase. It will also be understood that the guide face is also configured to guide the anti-uplift projection towards the second base plate by gravity when the second base plate accidentally comes out of its receiving space, for example, in the event of an impact from below the panel.

[0027] According to a particular embodiment, the first suspension side and the second suspension side are machined from the solid, or are formed by added parts or inserts.

[0028] The fixing can be achieved by any means, for example by screwing, by gluing, by nailing, or by a combination of these.

[0029] According to a particular embodiment, an upper surface of the suspension part forms an upper face of the panel configured to allow, in the state of the panel suspended from said two bases, the arrangement of at least one acoustic slab in a plenum above the panel.

[0030] For the purposes of the invention, "acoustic slab" means a plate made of a material capable of absorbing sound, in particular but not exclusively made of foam or rock wool.

[0031] According to a particular embodiment, the first support projection, the second support projection, the anti-lift projection, the stop face, where applicable the masking portion, and where applicable the guide face, extend over all or part of the space between the lateral sides of the panel.

[0032] Preferably, the first support projection, the second support projection, the anti-lift projection, the stop face, the masking portion (if applicable), and the guide face (if applicable), extend in sections over the space between the lateral sides of the panel, i.e., over only a portion of the space between the lateral sides of the panel. It will be understood, however, that, according to alternative designs, the first support projection, the second support projection, the anti-lift projection, the stop face, the masking portion (if applicable), or the guide face (if applicable), may extend over the entire space between the lateral sides of the panel, for example, by being supported by a cross member extending from one lateral side of the panel to the other.

[0033] According to a particular embodiment, the first support projection, the second support projection, the anti-lift projection, the stop face, where applicable the masking portion, and where applicable the guide face, are formed in longitudinal members extending from the first suspension side to the second suspension side.

[0034] Preferably, the panel comprises two stringers arranged on the two lateral sides of the panel. This configuration notably improves the stability of the panel when suspended from said two flanges, while limiting the panel's weight. It will be understood, however, that the stringers could be placed closer together in the direction from one lateral side to the other. It will also be understood that the panel could comprise a greater number of stringers. It will also be understood that pieces of the first support projection, pieces of the second support projection, pieces of the anti-uplift projection, pieces of the stop face, and, where applicable, pieces of the portion of masking, and where appropriate pieces of the guide face can be formed in different stringers.

[0035] Other technical solutions are possible for forming the first support projection, the second support projection, the anti-lift projection, the stop face, where applicable the masking portion, and where applicable the guide face on only parts of the space between the lateral sides of the panel, for example by using pads distributed on a suspension frame between the lateral sides of the panel, each pad being able to independently carry one or more of: a piece of the first support projection, a piece of the second support projection, a piece of the anti-lift projection, a piece of the stop face, where applicable a piece of the masking portion, or where applicable a piece of the guide face.

[0036] According to a particular embodiment, the stringers are spaced from each other in a direction from one lateral side to the other lateral side, at least one of the stringers located closest to one of the lateral sides is configured to be removably fixed to the rest of the panel, the decorative part of the rest of the panel is configured to be able to be cut to length after the at least one stringer configured to be removably fixed is removed, and the at least one stringer configured to be removably fixed is configured to be reattached to the rest of the panel after the cutting to length is carried out, such that a dimension of the panel in the direction from one of the lateral sides to the other of the lateral sides is adjustable in place during the installation of a suspended false ceiling.

[0037] A panel may in particular be prefabricated so as to be square, or may be prefabricated so as to be rectangular and configured to be adjusted to size on site so as to be square.

[0038] According to a particular embodiment, a lower portion of each stringer forms a counter-batten, and the panel further comprises a plurality of facing slats fixed to the counter-battens, preferably in notches formed in the lower faces of the counter-battens, the counter-battens and the facing slats together forming the decorative part.

[0039] According to a particular embodiment, one of the facing slats of the plurality of facing slats is configured to be fixed at the right of the masking portion, such that, in the state of the panel suspended from said two soles, said facing slat is arranged at the right of the first sole and masks at least partially it.

[0040] According to a particular embodiment, the panel further comprises at least one stiffener arranged between two stringers and configured to connect at least two adjacent facing slats together.

[0041] According to a particular embodiment, the panel is configured to be suspended from a support frame comprising said two support profiles and at least one additional profile connected perpendicularly to the support profiles and whose lower face is in the same plane as the lower faces of said two support profiles, the panel further comprises, on the second side of suspension, an anti-lift stop disposed at an interface between the lower portion of the suspension part and the decoration part, and the anti-lift stop being configured to come into contact with the lower face of an additional profile when, in the state of the panel suspended from said two bases, a movement, applied to the panel in a direction from the decoration part towards the suspension part, releases the second base received between the second support projection and the anti-lift projection.

[0042] The additional profiles can for example be of type T24.

[0043] Preferably, the panel includes an anti-lift stop on each lateral side of the panel.

[0044] According to a particular embodiment, the anti-lift stop is formed by one of the following: a shoulder attached to the panel and a rod attached to the panel, the shoulder preferably extending from the second side of suspension to the first side of suspension.

[0045] The rod may, for example, be cylindrical or parallelepiped-shaped. The anti-lift stop could also be in the form of a shoulder extending only at the second suspension side.

[0046] The anti-lift stop can be attached to the panel by being formed in one piece with an element of the panel or by being fixed to the panel, for example by screwing, gluing, nailing, or a combination of these.

[0047] According to a particular embodiment, at least one stiffener is arranged on the panel so that, in the state of the panel suspended from said two soles, it is positioned at the right of an additional profile, an upper face of said at least one stiffener being aligned with an upper face of the anti-lift stop or arranged below it.

[0048] The stiffener then has a function of masking the additional profile at the right of which it is positioned.

[0049] Preferably, the upper face of the stiffener is aligned with an upper face of the anti-uplift stop. One end of the stiffener, on the second suspension side, has a function analogous to the anti-uplift stop and is configured to abut against the lower face of an additional profile when, in the state of the panel suspended from said two flanges, a movement applied to the panel in a direction from the decorative part to the suspension part releases the The second sole plate is received between the second support projection and the anti-uplift projection in the second sole plate reception space. Less preferably, the upper face of the stiffener can be positioned below the upper face of the anti-uplift stop.

[0050] It will also be understood that a panel according to the invention can be used simply in combination with parallel support profiles, and that in this case, the stiffener does not have a function of masking an additional profile or of a stop against an additional profile.

[0051] Preferably, the anti-lift projection is configured to be rigid and to elastically deform the second sole when the second sole is inserted into the second sole receiving space by elastic interlocking. Preferably, the edges of the distal end of the anti-lift projection are beveled, or rounded, so as to facilitate the insertion and removal of the second sole from the second sole receiving space by elastic interlocking.

[0052] It will also be understood that, according to variants of the invention, the anti-lifting projection can be configured to deform elastically during elastic interlocking, such that elastic interlocking is permitted by elastic deformation of the anti-lifting projection, or by a combination of elastic deformation of the second sole and elastic deformation of the anti-lifting projection.

[0053] Thus, according to a particular embodiment, the anti-lifting projection is in the form of a flexible polymer lip, preferably made of rubber, slid into a fixing groove formed in the second side of the suspension.

[0054] The present invention also relates to a suspended false ceiling system, characterized in that the system comprises at least two support profiles configured to be suspended from a ceiling in a parallel manner, each support profile having a cross-section at least partially in the shape of an "L" and comprising at least one base formed on the floor side by the cross member of the "L", the system being configured such that the bases are parallel and coplanar, and the system further comprises at least one panel according to the present invention, each panel being configured to be disposed in a mounting space defined between two parallel and coplanar bases of said at least two support profiles, and configured to be suspended from said two bases using the suspension part.

[0055] Similar to an existing suspended ceiling, the support profiles are configured to be suspended from the ceiling of a building in which the suspended ceiling system is intended to be installed. The support profiles located at the periphery, or edge, of the suspended ceiling system are preferably configured to be fixed to the walls of the building rather than suspended from the ceiling.

[0056] The support profiles can be suspended at a distance from the ceiling using cables, rods, or similar means. The support profiles can be fixed to the walls by screwing, gluing, or any other means.

[0057] The support profiles are preferably support profiles with cross sections in the shape of an inverted "T", support profiles with cross sections in the shape of an "L", or a combination of support profiles in the shape of an "L" and support profiles in the shape of an inverted "T".

[0058] In particular, the support profiles configured to be suspended from the ceiling of the building are preferably in the shape of an inverted "T", while the support profiles intended to be fixed to the walls of the building are preferably in the shape of an "L".

[0059] The support profiles can for example be of type T24.

[0060] In its simplest form, the suspended false ceiling system according to the invention comprises two parallel support profiles and a panel according to the invention, but the number of support profiles and the number of panels are chosen according to the requirements to obtain the desired surface for the suspended false ceiling system.

[0061] Typically, a suspended ceiling system support frame comprises profiles called "bearers" which are configured to be fixed to the building structure, profiles called "main cross members" which are configured to extend perpendicularly to the bearers and be fixed to them, and profiles called "secondary cross members" which are configured to extend perpendicularly to the main cross members and be fixed to them. The secondary cross members are therefore parallel to the bearers.

[0062] According to the invention, the support profiles are preferably main crossbeams. However, according to variations, the support profiles could be load-bearing, secondary crossbeams, or a combination thereof. In this case, the panels would then be rotated 90 degrees.

[0063] According to a particular embodiment, the system further comprises at least one additional profile configured to be connected perpendicularly to the support profiles to form a support framework, the system being configured such that a lower face of the at least one additional profile is in the same plane as the lower faces of the support profiles.

[0064] Consistent with what has been indicated above, the additional profiles are preferably secondary carriers and spacers.

[0065] The additional profiles can for example be of type T24.

[0066] According to a particular embodiment, the system comprises at least three parallel support profiles and at least two panels according to the invention configured to be arranged in series, at least one of the support profiles having a cross-section transverse in the shape of an inverted "T" and being configured to have a first base configured to support the first suspension side of a first panel and a second base configured to support the second suspension side of a second panel, the first panel and the second panel being received in series on either side of said at least one support profile with a cross-section in the shape of an inverted "T".

[0067] According to a particular embodiment, at least the first panel includes a masking portion, and the masking portion of the first panel is configured so that, when the first panel and the second panel are suspended from the support profiles, it extends at least partially to the second support projection of the second panel.

[0068] The masking portion at least partially conceals the support profile from below the suspended ceiling system. The panels used in the suspended ceiling system are configured such that the masking portion of one panel does not interfere with the first suspension side of another panel arranged in series.

[0069] The present invention also relates to a kit for a panel according to the invention, characterized in that the kit includes a suspension part and a decoration part configured to be assembled together.

[0070] The suspension part and the decoration part can be configured to be assembled by any means, for example by screwing, gluing, nailing, or a combination thereof.

[0071] Particular embodiments of the present invention will now be described, with reference to the accompanying drawings.

[0088] [Fig.9b] is a perspective view of the panel of [Fig.9a], after a dimensional adjustment in the direction from one lateral side to the other.

[0089] If we refer first of all to [Fig.1], we can see that a rectangular panel 1 for a suspended false ceiling is shown there according to a first embodiment of the invention, comprising a suspension part 2 and a decoration part 3.

[0090] As will be described in more detail below with reference to [Fig.4a], the panel 1 is configured to be suspended from two parallel and coplanar flanges 121, 122 of two support profiles 120 with cross sections at least partially in the shape of "L" whose cross members of the "L" form said two flanges 121, 122.

[0091] According to the invention, the support profiles 120 are, preferably, support profiles 120 with cross sections in the shape of an inverted "T", support profiles 120 with cross sections in the shape of an "L", or a combination of support profiles 120 in the shape of an "L" and support profiles 120 in the shape of an inverted "T".

[0092] The support profiles 120 can simply be arranged parallel to each other. However, preferably, the support profiles 120 are arranged to form a support frame 110. [Fig. 3] shows an example of a support frame 110 which will be described in more detail below, when describing a suspended false ceiling system 100 according to the invention.

[0093] Furthermore, the dimensions of panel 1 are chosen according to the arrangement of the support profiles 120 from which it is intended to be suspended. In particular, panel 1 can be rectangular or square.

[0094] Referring also to Figures 4a to 4c, according to the invention, the suspension part 2 is configured to suspend the panel 1 from said two bases 121, 122, and comprises a first suspension side 21 having a first support projection 211 configured to, in a state of the panel 1 suspended from said two bases 121, 122, bear on a first base 121 of said two bases 121, 122, and a second opposite suspension side 22 having a second support projection 221 configured to, in the state of the panel 1 suspended from said two bases 121, 122, bear on a second base 122 of said two bases 121, 122.

[0095] According to the first embodiment shown in Figures 1 and 4a to 4c, the first suspension side 21 and the second suspension side 22 are machined from a solid piece. However, alternatively, the first suspension side 21 and the second suspension side 22 can be formed by inserts or add-on parts. Figure 5b shows an alternative with the second suspension side 22 formed by an insert attached to the suspension part 2. The attachment can be made by any means, for example by screwing, gluing, nailing, or a combination thereof. Similarly, the first suspension side 21 can be formed by an insert or add-on part attached to the suspension part 2.

[0096] If we refer to [Fig.4a], we can see that the panel 1 is configured in such a way that a distance, in projection in a so-called profile plane perpendicular to the first and second suspension sides 21, 22, between a distal end 21la of the first support projection 211 and a distal end 221a of the second support projection 221 is greater than a spacing of said two soles 121, 122.

[0097] In the first embodiment of panel 1, a distance, projected in the profile plane, between a proximal end 211b of the first support projection 211 and a proximal end 221b of the second support projection 221 is less than the spacing of said two soles 121, 122. According to a less preferred variant, the distance, projected in the profile plane, between the proximal end 211b of the first support projection 211 and the proximal end 221b of the second support projection 221 can be equal to the spacing of said two soles 121, 122.

[0098] Referring to Figures 4b and 4c, it can be seen that the first support projection 211 defines, in projection in the profile plane, an upper side of a first footing reception space 212, and the second support projection 221 defines, in projection in the profile plane, an upper side of a second footing reception space 222.

[0099] In the state of the panel 1 suspended from said two soles 121, 122, the receiving space of the first sole 212 is configured to receive the first sole 121 and the receiving space of the second sole 222 is configured to receive the second sole 122. It will therefore be understood that the receiving space of the first sole 212 and the receiving space of the second sole 222 extend respectively from one of the lateral sides 11 connecting the first and second suspension sides 21, 22 to the other of the lateral sides 11, so as to receive the respective sole 121, 122.

[0100] The decorative part 3 is attached to a lower portion of the suspension part 2 and is configured to be oriented towards the ground, in the state of the panel 1 suspended from said two bases 121, 122.

[0101] Preferably, the lower portion of the suspension part 2 is formed in one piece with one or more elements of the decoration part 3. It will be understood, however, that, for example to facilitate the manufacture of the panel 1, the lower portion of the suspension part 2 may be secured by fixing to one or more elements of the decoration part 3. It will also be understood that the fixing may be effected by any means, for example by screwing, gluing, nailing, or a combination thereof.

[0102] Referring to Figures 1, 4a and 4c, it can be seen that the decorative part 3 is fixed in a recess from the second suspension side 22 of the suspension part 2 so as to form a clearance 4 under the second suspension side 22. The clearance 4 extends in depth along the direction of the second support projection 221, and in width from one of the lateral sides 11 to the other of the lateral sides 11.

[0103] The panel 1 is further configured such that a distance, projected onto the profile plane, between a bottom 4a of the clearance 4 and the distal end 21la of the first support projection 211 is equal to the spacing of said two flanges 121, 122. The clearance 4 is configured to temporarily receive a distal end 122a of the second flange 122 during a panel mounting phase from below the support profiles 120. According to a less preferred embodiment, the distance, projected onto the profile plane, between the bottom 4a of the clearance 4 and the distal end 21la of the first support projection 211 may be less than the spacing of said two flanges 121, 122.

[0104] By referring to Figures 1, 4a and 4c, it can be seen that, according to the invention, the panel 1 further comprises, on the second suspension side 22, an anti-uplift projection 223 configured to extend parallel to the second support projection 221 and to extend, in projection in the profile plane, between the second support projection 221 and the clearance 4 so as to define a lower side of the receiving space of the second footing 222.

[0105] Furthermore, the anti-uplift projection 223 extends such that, in projection onto the profile plane, a distal end 223a of the anti-uplift projection 223 is set back from the distal end 221a of the second support projection 221, and that a distance, in projection in the profile plane, between the proximal end 211b of the first support projection 211 and the distal end 223a of the anti-uplift projection 223 is greater than the spacing of said two soles 121, 122.

[0106] Furthermore, the anti-lift projection 223 is configured so that, in the state of the panel 1 suspended from said two soles 121, 122, it is disposed under the second sole 122, such that the panel 1 is configured to receive the second sole 122 between the second support projection 221 and the anti-lift projection 223 by elastic interlocking relationship between the anti-lift projection 223 and the second sole 122.

[0107] Preferably, the anti-lift projection 223 is configured to be rigid and to elastically deform the second sole 122 when the second sole 122 is inserted into the receiving space of the second sole 222 by elastic interlocking. Preferably, the edges of the distal end 223a of the anti-lift projection 233 are beveled, or rounded, so as to facilitate the insertion and removal of the second sole 122 into the receiving space of the second sole 222 by elastic interlocking.

[0108] According to variants of the invention, the anti-lift projection 223 can be configured to deform elastically during elastic interlocking, such that elastic interlocking is enabled by elastic deformation of the anti-lift projection 223, or by a combination of elastic deformation of the second sole 122 and elastic deformation of the anti-lift projection 223. Thus, according to one variant, the anti-lift projection 223 can, for example, be in the form of a flexible polymer lip, preferably made of rubber, slid into a fixing groove formed in the second suspension side 22.

[0109] As can be seen more clearly in Figures 4a and 4c, in panel 1 according to the first embodiment, the clearance 4 is configured such that panel 1 further includes a guide face 7 configured to extend, in projection in the profile plane, obliquely between the bottom 4a of the clearance 4 and the distal end 223a of the anti-uplift projection 223, at an angle of 40 degrees with respect to a horizontal axis, and therefore at an angle of 50 degrees with respect to a vertical axis.

[0110] According to variants not shown, the panel 1 can be configured so that the guide face 7 extends obliquely at an angle between 30 and 60 degrees.

[0111] The guide face 7 is configured to guide the anti-uplift projection 223 towards the second flange 122 by gravity during the panel 1 mounting phase. The guide face 7 is also configured to guide the anti-uplift projection 223 towards the second flange 122 by gravity when the second flange 122 is used. accidentally from the receiving space of second sole 222, for example in the case of an impact from below panel 1.

[0112] By referring to Figures 1, 4a and 4b, it can be seen that the panel 1 further comprises a stop face 5. The stop face 5 is formed at the first suspension side 21 and is configured to extend, in projection in the profile plane, from a proximal end of a lower face of the first support projection 211 towards a lower face of the panel 1.

[0113] The buttress face 5 defines, in projection onto the profile plane, a lateral side of the first footing reception space 212. Preferably, and as is more clearly seen in [Fig. 4b], the buttress face 5 is vertical. According to unshown variants, the buttress face 5 could extend obliquely.

[0114] It can be specified here that, preferably, the lower face of the first support projection 211 extends in the same plane as a lower face of the second support projection 221.

[0115] The panel 1 according to the first embodiment further comprises, on the first suspension side 21, a masking portion 6 configured to extend parallel to the first support projection 211 and to extend, in projection in the profile plane, from the abutment face 5 so as to define a lower side of the receiving space of the first flange 212. In the state of the panel 1 suspended from said two flanges 121, 122, the masking portion 6 is configured to be disposed under the first flange 121. The panel 1 according to the first embodiment is further configured such that a distance, in projection in the profile plane, between a distal end 6a of the masking portion 6 and the proximal end 221b of the second support projection 221 is greater than the spacing of said two flanges 121, 122.

[0116] If, in the state of the panel 1 suspended from said two soles 121, 122, a movement (upward vertical in use) is applied to the panel 1 in a direction from the decoration part 3 towards the suspension part 2, at the level of the first suspension side 21, the masking portion 6 comes to rest against the first sole 121, so that the first sole 121 does not come out of the receiving space of the first sole 212.

[0117] In an alternative variant not shown, a distance, projected onto the profile plane, between a lower end 5a of the abutment face 5 and the proximal end 221b of the second support projection 221 is greater than the distance between said two flanges 121, 122. In this variant, if, in the state of the panel 1 suspended from said two flanges 121, 122, a movement is applied to the panel 1 in a direction from the decorative part 3 towards the suspension part 2, at the level of the first suspension side 21, it is the abutment face 5 that comes abutting against the first flange 121, so that the first sole 121 does not come out of the receiving space of the first sole 212.

[0118] This variant may, or may not, include a masking portion 6, configured to, in the state of the panel 1 suspended from said two soles 121, 122, be disposed under the first sole 121.

[0119] The length of the masking portion 6 is chosen according to the needs to mask part or all of the first footing 121 from the underside of the panel 1.

[0120] In the panel 1 according to the first embodiment shown in Figures 1 and 4a to 4c, the masking portion 6 extends beyond the first support projection 211, such that, in projection in the profile plane, the distal end 21la of the first support projection 211 is recessed relative to the distal end 6a of the masking portion 6.

[0121] According to a variant shown in [Fig.5a], the masking portion 6 extends to the first support projection 211, such that, in projection in the profile plane, the distal end 21la of the first projection 211 is aligned with the distal end 6a of the masking portion 6.

[0122] Furthermore, referring to Figures 4a to 4c, it can be seen that, in the panel 1 according to the first embodiment, an upper surface 23 of the suspension part 2 forms an upper face of the panel 1 configured to allow, in the state of the panel 1 suspended from said two bases 121, 122, the arrangement of an acoustic slab D in a plenum above the panel 1.

[0123] According to variants not shown, panel 1 can be configured to allow a user to have several acoustic tiles D, superimposed or arranged side by side, in the plenum.

[0124] Fig. 8 also presents a perspective view of a suspended false ceiling system 100 according to the invention, above which acoustic tiles D are arranged. The suspended false ceiling system 100 will be described in more detail below.

[0125] By referring more particularly to [Fig. 1], it can be seen that, in the panel 1 according to the first embodiment, the first support projection 211, the second support projection 221, the anti-lift projection 223, the stop face 5, the masking portion 6, and the guide face 7, extend in pieces over the space between the lateral sides 11 of the panel 1, that is to say over only a part of the space between the lateral sides 11 of the panel 1.

[0126] According to variants however, the first support projection 211, the second support projection 221, the anti-lift projection 223, the stop face 5, the masking portion 6, or the guide face 7, can extend over the entire space between the lateral sides 11 of the panel 1, for example by being supported by a cross member extending from one of the lateral sides 11 of the panel 1 to the other of the lateral sides 11.

[0127] Furthermore, in the first embodiment, the first support projection 211, the second support projection 221, the anti-lift projection 223, the stop face 5, the masking portion 6, and the guide face 7, are formed in longitudinal members 2a extending from the first suspension side 21 to the second suspension side 22.

[0128] Furthermore, in the first embodiment of panel 1, panel 1 comprises two stringers 2a arranged on the two lateral sides 11 of panel 1. This configuration notably improves the stability of panel 1 when suspended from said two flanges 121, 122, while limiting the weight of panel 1. It will be understood, however, that the stringers 2a could be brought closer together in the direction from one lateral side 11 to the other lateral side 11. It will also be understood that, according to variants not shown, panel 1 could comprise a greater number of stringers 2a.It will also be understood that, according to variants not shown, pieces of the first support projection 211, pieces of the second support projection 221, pieces of the anti-uplift projection 223, pieces of the stop face 5, pieces of the masking portion 6, and pieces of the guide face 7 can be formed in different stringers 2a.

[0129] Obviously, other technical solutions are possible for forming the first support projection 211, the second support projection 221, the anti-lift projection 223, the stop face 5, the masking portion 6, and the guide face 7 on only parts of the space between the lateral sides 11 of the panel 1, for example by using studs distributed on a suspension frame between the lateral sides 11 of the panel 1, each stud being able to independently carry one or more of: a piece of the first support projection 211, a piece of the second support projection 221, a piece of the anti-lift projection 223, a piece of the stop face 5, a piece of the masking portion 6, or a piece of the guide face 7.

[0130] Furthermore, referring to Figures 1 and 4a to 4c, it can be seen that, in the first embodiment of panel 1, a lower portion of each stringer 2a forms a counter batten 3a. In addition, panel 1 further comprises a plurality of facing battens 3b attached to the counter battens 3a. Advantageously, the facing battens 3b are attached to the counter battens 3a in notches formed in the lower faces of the counter battens 3a. In the first embodiment of panel 1, the counter battens 3a and the facing battens 3b together form the decorative portion 3.

[0131] As can be seen more clearly in Figures 4a and 4b, in the first embodiment of panel 1, one of the facing slats 3b of the plurality of facing slats 3b is configured to be fixed opposite the masking portion 6, such that, in the state of the panel suspended from said two flanges 121, 122, said Facing strip 3b is positioned opposite the first footing 121 and at least partially masks it.

[0132] Referring to [Fig. 1], it can be seen that, in the first embodiment of panel 1, panel 1 further comprises a stiffener 3c arranged between two stringers 2a, parallel to them, and configured to connect the facing strips 3b together. According to variants not shown, panel 1 may comprise a greater number of stiffeners 3c, and each stiffener 3c may be configured to connect at least two adjacent facing strips 3b together.

[0133] Furthermore, in the first embodiment shown in Figures 1 and 4a to 4c, the stringers 2a are spaced from each other in a direction from one lateral side 11 to the other lateral side 11. The stringers 2a located closest to each of the lateral sides 11 are configured to be removably fixed to the rest of the panel 1. The decorative portion 3 of the rest of the panel 1 is configured to be able to be cut to length after one of the stringers 2a configured to be removably fixed is removed, and the removed stringer 2a configured to be removably fixed is configured to be reattached to the rest of the panel 1 after the cut to length is made.

[0134] Thus, a dimension of the panel 1 along the direction from one of the lateral sides 11 to the other of the lateral sides 11 is adjustable on site during the installation of a suspended false ceiling.

[0135] Fig. 9a shows a panel according to the first embodiment, before dimensional adjustment, and Fig. 9b shows the same panel 1, after dimensional adjustment in the direction from one lateral side 11 to the other lateral side 11. A panel 1 can in particular be prefabricated so as to be square, or can be prefabricated so as to be rectangular and configured to be dimensional adjusted on site so as to be square.

[0136] Alternatively, only one of the longerons 2a arranged closest to the lateral sides 11 could be fixed in a removable manner, so that the dimensional adjustment would necessarily be made on the side of the longeron 2a fixed in a removable manner.

[0137] In the panel 1 according to the first embodiment, a dimension of the panel 1 in a direction from the first suspension side 21 to the second suspension side 22 can also be adjusted. For this purpose, the panel 1 is configured so that it can be cut from one lateral side 11 to the other lateral side 11. During such a cut, either the first suspension side 21 or the second suspension side 22 is separated and removed from the panel 1. The panel 1 is further configured so that the cut suspension side 21, 22 can be reshaped, either by trimming the panel 1 or by attaching a piece or insert. [Fig. 5a] shows an example of a first suspension side trimmed from the panel 1 and [Fig. 5b] shows a Example of the second side of suspension 22 reformed by an added part. Alternatively, an L-shaped edge bracket could replace the added part, supported not by the base 121 but by an additional profile.

[0138] Thus, the dimension of the panel 1 along the direction from the first suspension side 21 to the second suspension side 22 is adjustable on site during the installation of a suspended false ceiling.

[0139] In the first embodiment of panel 1, shown in Figures 1 and 4a to 4c, panel 1 is configured to be suspended from a support frame 110 comprising said two support profiles 120 and at least one additional profile 130 connected perpendicularly to the support profiles 120 and of which a lower face is in the same plane as the lower faces of said two support profiles 120.

[0140] Furthermore, the panel 1 also includes, on the second suspension side 22, an anti-lift stop 8 disposed at an interface between the lower portion of the suspension part 2 and the decoration part 3. The anti-lift stop 8 is configured to come into contact with the lower face of an additional profile 130 when, in the state of the panel 1 suspended from said two bases 121, 122, a movement, applied to the panel 1 in a direction from the decoration part 3 towards the suspension part 2, releases the second base 122 received between the second support projection 221 and the anti-lift projection 223 in the receiving space of the second base 222.

[0141] In the first embodiment of the panel 1, the anti-lift stop 8 is formed by a shoulder attached to the panel 1, the shoulder extending from the second suspension side 22 to the first suspension side 21. In addition, each longitudinal member 2a includes an anti-lift stop 8.

[0142] According to variants, the anti-lift stop 8 could take another form, for example the anti-lift stop 8 could be in the form of a shoulder extending only at the level of the second suspension side 22, or in the form of a rod, for example cylindrical or parallelepiped, attached to the panel 1 at the level of the second suspension side 22.

[0143] The anti-lift stop 8 can also be attached to the panel 1 by being formed in one piece with an element of the panel 1 or by being fixed to the panel 1, for example by screwing, gluing, nailing, or a combination of these.

[0144] Furthermore, as indicated above, the panel 1 according to the first embodiment is preferably configured to be used in combination with a support frame 110 comprising at least one additional profile 130. In addition, in the first embodiment of panel 1, the stiffener 3c is arranged on panel 1 so that, in the state of panel 1 suspended from said two flanges 121, 122, it is positioned at the right of an additional profile 130 of the support frame 110, and an upper face of the stiffener 3c is aligned with an upper face of the anti-lift stop 8.

[0145] The stiffener 3c can then have a function of masking the additional profile 130 at the right of which it is positioned.

[0146] One end of the stiffener 3c, on the second suspension side 22, can also have a function analogous to the anti-uplift stop 8 and is configured to abut against the lower face of an additional profile 130 when, in the state of the panel 1 suspended from said two flanges 121, 122, a movement, applied to the panel 1 in a direction from the decorative part 3 towards the suspension part 2, releases the second flange 122 received between the second support projection 221 and the anti-uplift projection 223 in the receiving space of the second flange 222. According to a less preferred embodiment, the upper face of the stiffener 3c can be arranged below the upper face of the anti-uplift stop 8.

[0147] The panel 1 according to the first embodiment can be used simply in combination with parallel support profiles 120, and in this case, the stiffener 3c does not have a function of masking an additional profile 130 nor of a stop against an additional profile 130.

[0148] Furthermore, a panel 1 according to the first embodiment is preferably configured such that, in projection in the profile plane, a distance between the first support projection 211 and the masking portion 6 is greater than a distance between the second support projection 221 and the anti-lift projection 223.

[0149] This configuration allows, in particular, two base plates to be slid into the receiving space of the first base plate 212, which may be necessary when installing a suspended false ceiling at a junction with a wall. Indeed, at the junction with a wall, it is generally necessary to accommodate a base plate of a support profile 120 fixed to the wall, in addition to the first base plate 121 of a support profile 120 suspended from the ceiling.

[0150] Figure 2 shows a panel 1' according to a second embodiment of the invention. The panel 1' according to the second embodiment of the invention is identical to the panel 1 according to the first embodiment of the invention, except that the panel 1 according to the first embodiment includes an anti-lift stop 8 and the panel 1' according to the second embodiment does not include an anti-lift stop 8.

[0151] The second embodiment of panel 1' may be preferred, in particular because it allows for a panel 1' that is lighter and cheaper than the first embodiment.

[0152] With reference to Figures 6a to 6c, we will now quickly describe a method of mounting a panel 1 according to the invention on two support profiles 120, from the underside of the support profiles 120, and a method of dismantling the panel 1 from the underside of the support profiles 120.

[0153] Fig. 6a shows a mounting phase of a panel 1 on two support profiles 120.

[0154] The method for mounting panel 1 comprises the steps of:

[0155] - tilt panel 1, and place the bottom 4a of clearance 4 against the distal end 122a of the second sole 122;

[0156] - lift the first suspension side 21, so that the first protrusion support 211 is located above the first footing 121;

[0157] - shift panel 1 towards the first sole 121 to slide the first sole 121 in the receiving space of first sole 212; and

[0158] - pull on the second side of the suspension 22, so as to house the second sole 122 in the receiving space of the second sole 222, by elastic interlocking relationship between the anti-lifting projection 223 and the distal end 122a of the second sole 122.

[0159] Fig. 6b shows the panel 1 in a state mounted on the two support profiles 120 and suspended from said two bases 121, 122.

[0160] Fig. 6c shows a phase of dismantling panel 1.

[0161] The method for dismantling panel 1 comprises the steps of:

[0162] - push on the first side of suspension 21, so as to release the second sole 122 of the receiving space of the second sole 222, by elastic deformation between the second sole 122 and the anti-lifting projection 223;

[0163] - tilt panel 1, and shift panel 1 towards the second base 122, of in order to bring the distal end 122a of the second sole 122 against the bottom 4a of the clearance 4 and to slide the first sole 121 out of the receiving space of the first sole 212; and

[0164] - go down and retrieve panel 1.

[0165] The present invention also relates to a kit for a panel 1 according to the invention.

[0166] The kit includes a suspension part 2 and a decorative part 3 configured to be assembled together. The suspension part 2 and the decorative part 3 can be configured to be assembled by any means, for example by screwing, gluing, nailing, or a combination thereof.

[0167] The present invention also relates to a suspended false ceiling system 100.

[0168] Referring to Figures 7a, 7b and 8, one can see that a suspended false ceiling system 100 is shown therein according to an embodiment of the invention, including support profiles 120 configured to be suspended from a ceiling in a parallel manner, and panels 1 according to the invention.

[0169] In the embodiment illustrated in Figures 7a, 7b and 8, the system 100 comprises panels 1 according to the first embodiment shown in [Fig. 1]. According to variants, the system 100 could, however, comprise panels 1' according to the second embodiment shown in [Fig. 2], or according to another variant of the invention.

[0170] Similar to an existing suspended ceiling, the support profiles 120 are configured to be suspended from the ceiling of a building in which the suspended ceiling system 100 is intended to be installed. The support profiles 120 located at the periphery, or edge, of the suspended ceiling system 100 are thus preferably configured to be fixed to the walls of the building rather than suspended from the ceiling.

[0171] The support profiles 120 can be suspended at a distance from the ceiling using cables, rods, or similar means. The support profiles 120 can be fixed to the walls by screwing, gluing, or any other means.

[0172] In its simplest form, the suspended false ceiling system 100 according to the invention comprises two parallel support profiles 120 and a panel 1 according to the invention, but the number of support profiles 120 and the number of panels 1 are chosen according to the requirements to obtain the desired surface for the suspended false ceiling system 100.

[0173] The support profiles 120 can simply be arranged parallel to each other. However, preferably, the support profiles 120 are arranged to form a support frame 110. [Fig. 3] shows an example of a support frame 110 of a suspended false ceiling system 100 according to the invention.

[0174] By referring to Figures 3, 7a, 7b and 8, it can be seen that the system 100 according to the embodiment shown further comprises additional profiles 130 configured to be connected perpendicularly to the support profiles 120 to form a support frame 110. In addition, the system 100 is configured such that a lower face of each additional profile 130 is in the same plane as lower faces of the support profiles 120.

[0175] According to the invention, each support profile 120 has a cross-section at least partially in the shape of an "L" and includes at least one flange 121, 122 formed on the ground side by the cross member of the "L". The system 100 is further configured such that the flanges 121, 122 are parallel and coplanar.

[0176] According to the invention, the support profiles 120 are preferably support profiles 120 with inverted "T" shaped cross-sections, support profiles 120 with L-shaped cross-sections, or a combination of L-shaped 120 support profiles and inverted T-shaped 120 support profiles.

[0177] In particular, the 120 support profiles configured to be suspended from the building ceiling are preferably inverted T-shaped, while the 120 support profiles intended to be fixed to the building walls are preferably L-shaped.

[0178] Typically, a suspended ceiling system support framework comprises profiles called "bearers" which are configured to be fixed to the building structure, profiles called "main cross members" which are configured to extend perpendicularly to the bearers and be fixed to them, and profiles called "secondary cross members" which are configured to extend perpendicularly to the main cross members and be fixed to them. The secondary cross members are therefore parallel to the bearers.

[0179] According to the embodiment shown in Figures 3, 7a, 7b, and 8, the support profiles 120 are primary cross members, and the additional profiles 130 are secondary cross members and cross members. It will be understood, however, that in variants not shown, the support profiles 120 could be cross members, secondary cross members, or a combination thereof. In this case, the panels 1 would be rotated 90 degrees relative to what is shown in Figures 7a, 7b, and 8.

[0180] The support profiles 120 and the additional profiles 130 can also, for example, be of type T24.

[0181] Furthermore, each panel 1 of the system 100 is configured to be arranged in a defined mounting space between two parallel and coplanar base plates 121, 122 of said support profiles 120, and is configured to be suspended from said two base plates 121, 122 using the suspension part 2.

[0182] According to a preferred embodiment of the system 100, the system 100 comprises at least three parallel support profiles 120 and at least two panels 1 according to the invention configured to be arranged in series. At least one of the support profiles 120 has an inverted "T" shaped cross-section and is configured to have a first flange 121 configured to support the first suspension side 21 of a first panel 1 and a second flange 122 configured to support the second suspension side 22 of a second panel 1, the first panel 1 and the second panel 1 being received in series on either side of said at least one support profile 120 with an inverted "T" shaped cross-section.

[0183] According to an advantageous embodiment of system 100, the first panel 1 comprises a masking portion 6, and the masking portion 6 of the first panel 1 is configured so that, when the first panel 1 and the second panel 1 are suspended from the support profiles 120, extend at least partially to the second support projection 221 of the second panel 1.

[0184] The masking portion 6 at least partially masks the support profile 120 from below the suspended false ceiling system 100. The panels 1 used in the suspended false ceiling system 100 are configured such that the masking portion 6 of a panel 1 does not interfere with the first suspension side 21 of another panel 1 arranged in series.

[0185] It is understood that the particular embodiments which have just been described have been given by way of indication and not limitation, and that modifications may be made without departing from the scope of the present invention.
