Description

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

[0002] Suspended ceiling systems comprising panels suspended using 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 panel system for ceiling decoration 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 involuntary shock applied from below a panel could lift the panel, which could then be incorrectly positioned or even fall.

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

[0006] The present invention aims in particular to solve the problems indicated above by providing a suspended false ceiling panel, 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" whose crosspieces of the "L" form said two flanges, the panel comprising: a suspension part, 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, in projection in a so-called 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 the spacing of said two soles, and the first support projection defining, in projection in the profile plane, an upper side of a first sole receiving space, and the second support projection defining, in projection in the profile plane, an upper side of a second sole receiving space, and the first sole receiving space and the second sole receiving 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,secured to a lower portion of the suspension part and configured to be oriented towards the ground, the decorative part being secured 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 in the direction of the second support projection and in width from one of the lateral sides to the other of the lateral sides, a distance, in projection in 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 phase of mounting the panel from below the support profiles; and an abutment face, formed on the first suspension side and configured to extend, in projection in the profile plane,from a proximal end of a lower face of the first support projection towards a lower face of the panel, and the abutment face defining, in projection in the profile plane, a lateral side of the first sole receiving space; characterized in that the panel further comprises, on the second suspension side, an anti-lift 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 sole receiving space, the anti-lift projection extending such that, in projection in the profile plane, a distal end of the anti-lift projection is set back relative to the distal end of the second support projection and that a distance, in projection in the profile plane,between the proximal end of the first support projection and the distal end of the anti-lift projection is greater than the spacing of said two flanges, and the anti-lift projection being configured to, in the state of the panel suspended from said two flanges, be arranged under the second flange, such that the panel is configured to receive the second flange between the second support projection and the anti-lift projection by elastic interlocking relationship between the anti-lift projection and the second flange.,

[0008] This configuration prevents, in particular, that, during use, an involuntary shock applied from below the panel does not lift 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 decoration portion to the suspension portion, must exceed a predefined value to release the second sole received between the second support projection and the anti-lift projection in the second sole receiving space. Preferably, the predefined value is chosen to allow a user to disassemble the panel by hand.

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

[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] Fixing may be achieved by any means, for example by screwing, gluing, nailing, or 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, in use, allowing a lower face of the panel to be horizontal.

[0016] According to a particular embodiment, a distance, in projection 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 flanges, a movement is applied to the panel in a direction from the decoration part toward the suspension part (vertical upward movement in use), at the first suspension side, the abutment face abuts against the first flange, such that the first flange does not come out of the first flange receiving 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 space for receiving the first sole, and a distance, in projection in the profile plane, between a distal end of the masking portion and the 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 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 into abutment 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 set back relative to the distal end of the masking portion.

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

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

[0023] This configuration allows, in particular, two soles to be slid into the space for receiving the first sole, 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 sole of a support profile fixed to the wall, in addition to the first sole of a support profile suspended from the ceiling.

[0024] According to a particular embodiment, the clearance is configured such that the panel further comprises 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-lift projection, at an angle of between 30 and 60 degrees, the guide face being configured to, during the panel assembly phase, guide the anti-lift projection towards the second sole, by gravity.

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

[0026] The guide face is configured to, during the panel assembly phase, guide the anti-lift projection towards the second sole, by gravity. It will also be understood that the guide face is also configured to guide the anti-lift projection towards the second sole, by gravity, when in use the second sole accidentally leaves the second sole receiving space, for example in the case of an impact from below the panel.

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

[0028] Fixing may be achieved by any means, for example by screwing, gluing, nailing, or 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 tile in a plenum above the panel.

[0030] For the purposes of the invention, the term "acoustic slab" means a plate made of 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 abutment face, where applicable the masking portion, and where applicable the guide face, extend in pieces over the space between the lateral sides of the panel, that is to say over only a part of the space between the lateral sides of the panel. It will be understood, however, that, according to variants, the first support projection, the second support projection, the anti-lift projection, the abutment face, where applicable the masking portion, or where applicable the guide face, may extend over the entire space between the lateral sides of the panel, for example by being carried by a crosspiece extending from one of the lateral sides 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 side members extending from the first suspension side to the second suspension side.

[0034] Preferably, the panel comprises two longitudinal members arranged on both lateral sides of the panel. This configuration makes it possible in particular to improve the stability of the panel in the state of the panel suspended from said two flanges, while limiting the weight of the panel. It will be understood, however, that the longitudinal members could be brought closer to each other in the direction from one lateral side to the other. It will also be understood that the panel could comprise a greater number of longitudinal members. It will also be understood that pieces of the first support projection, pieces of the second support projection, pieces of the anti-lift projection, pieces of the abutment face, where appropriate pieces of the masking portion, and where appropriate pieces of the guide face may be formed in different longitudinal members.

[0035] Other technical solutions are possible for forming the first support projection, the second support projection, the anti-lift projection, the abutment face, where appropriate the masking portion, and where appropriate the guide face on only parts of the space between the lateral sides of the panel, for example by using studs distributed on a suspension frame between the lateral sides of the panel, each stud possibly 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 abutment face, where appropriate a piece of the masking portion, or where appropriate a piece of the guide face.

[0036] According to a particular embodiment, the stringers are spaced apart from each other in a direction from one lateral side to the other lateral side, at least one of the stringers disposed closest to one of the lateral sides is configured to be removably attached to the remainder of the panel, the decorative portion of the remainder of the panel is configured to be capable of being cut to length after the at least one stringer configured to be removably attached is removed, and the at least one stringer configured to be removably attached is configured to be reattached to the remainder of the panel after the cutting to length is performed, 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 on site when installing a suspended false ceiling.

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

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

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

[0040] According to a particular embodiment, the panel further comprises at least one stiffener arranged between two side members and configured to connect at least two neighboring 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 of which a lower face is in the same plane as lower faces of said two support profiles, the panel further comprises, on the second suspension side, an anti-lift stop arranged at an interface between the lower portion of the suspension part and the decorative part, and the anti-lift stop being 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 going from the decorative part towards the suspension part, releases the second flange 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 at each lateral side of the panel.

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

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

[0046] The anti-lift stop may be secured to the panel by being formed integrally with a member of the panel or by being fixed to the panel, for example by screwing, gluing, nailing, or a combination thereof.

[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 flanges, it is arranged in line with 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 the latter.

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

[0049] Preferably, the upper face of the stiffener is aligned with an upper face of the anti-lift stop. One end of the stiffener, on the second suspension side, has a function similar to the anti-lift 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 going from the decorative part towards the suspension part, releases the second flange received between the second support projection and the anti-lift projection in the second flange receiving space. Less preferably, the upper face of the stiffener can be arranged below the upper face of the anti-lift 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 stopping against an additional profile.

[0051] Preferably, the anti-lift projection is configured to be rigid and elastically deform the second sole when the second sole is inserted into the second sole receiving space by elastic fitting. Still 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 into the second sole receiving space by elastic fitting.

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

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

[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 flange formed on the ground side by the crosspiece of the "L", the system being configured such that the flanges are parallel and coplanar, and the system further comprises at least one panel according to the present invention, each panel being configured to be arranged in a mounting space defined between two parallel and coplanar flanges of said at least two support profiles, and configured to be suspended from said two flanges 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 arranged at the periphery, or edge, of the suspended ceiling system are preferably configured to be fixed to 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 inverted "T" shaped cross sections, support profiles with "L" shaped cross sections, or a combination of "L" shaped support profiles and inverted "T" shaped support profiles.

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

[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 one panel according to the invention, but the number of support profiles and the number of panels are chosen as required to obtain the desired surface area for the suspended false ceiling system.

[0061] Typically, a suspended ceiling system support frame includes sections called "bearers" that are configured to be attached to the building structure, sections called "main struts" that are configured to extend perpendicular to the bearers and be attached to them, and sections called "secondary struts" that are configured to extend perpendicular to the main struts and be attached to them. The secondary struts are therefore parallel to the bearers.

[0062] According to the invention, the support profiles are preferably main struts. However, according to variants, the support profiles could be carriers, secondary struts, 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 frame, the system being configured such that a lower face of the at least one additional profile is in the same plane as 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 an inverted "T" shaped cross section and being configured to have a first sole configured to support the first suspension side of a first panel and a second sole 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 an inverted "T" shaped cross section.

[0067] According to a particular embodiment, at least the first panel comprises a masking portion, and the masking portion of the first panel is configured to, when the first panel and the second panel are suspended from the support profiles, extend at least partially in line with the second support projection of the second panel.

[0068] The masking portion at least partially masks 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 comprises a suspension part and a decoration part configured to be assembled together.

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

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

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

[0073] If we first refer to the Figure 1 , it can be seen that a rectangular panel 1 for a suspended false ceiling according to a first embodiment of the invention is shown, comprising a suspension part 2 and a decorative part 3.

[0074] As will be described in more detail below with reference to the Figure 4a , the panel 1 is configured to be suspended from two parallel and coplanar soles 121, 122 of two support profiles 120 with cross sections at least partially in the shape of an “L” whose crosspieces of the “L” form said two soles 121, 122.

[0075] 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 support profiles 120 and inverted "T" shaped support profiles 120.

[0076] The support profiles 120 may simply be arranged parallel to each other. However, preferably, the support profiles 120 are arranged to form a support frame 110. The Figure 3 presents 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.

[0077] Furthermore, the dimensions of the panel 1 are chosen according to the arrangement of the support profiles 120 from which it is intended to be suspended. In particular, the panel 1 may be rectangular or square.

[0078] Also referring to the Figures 4a à 4c , according to the invention, the suspension part 2 is configured to suspend the panel 1 from said two soles 121, 122, and comprises a first suspension side 21 having a first bearing projection 211 configured to, in a state of the panel 1 suspended from said two soles 121, 122, bear on a first sole 121 of said two soles 121, 122, and a second opposite suspension side 22 having a second bearing projection 221 configured to, in the state of the panel 1 suspended from said two soles 121, 122, bear on a second sole 122 of said two soles 121, 122.

[0079] According to the first embodiment shown in the Figures 1 And 4a à 4c , the first suspension side 21 and the second suspension side 22 are cut from the mass. However, as a variant, the first suspension side 21 and the second suspension side 22 can be formed by added parts or inserts. The Figure 5b has a variant with the second suspension side 22 formed by an insert fixed to the suspension part 2. The fixing can be carried out by any means, for example by screwing, by gluing, by nailing, or by a combination of these. Similarly, the first suspension side 21 can be formed by an insert or an insert fixed to the suspension part 2.

[0080] If we refer to the Figure 4a , it can be seen that the panel 1 is configured such 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 211a 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.

[0081] In the first embodiment of the panel 1, a distance, in projection 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, in projection 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 may be equal to the spacing of said two soles 121, 122.

[0082] If we refer to the 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 sole receiving space 212, and the second support projection 221 defines, in projection in the profile plane, an upper side of a second sole receiving space 222.

[0083] In the state of the panel 1 suspended from said two flanges 121, 122, the first flange receiving space 212 is configured to receive the first flange 121 and the second flange receiving space 222 is configured to receive the second flange 122. It will therefore be understood that the first flange receiving space 212 and the second flange receiving space 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 flange 121, 122.

[0084] The decorative part 3 is secured 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 soles 121, 122.

[0085] Preferably, the lower portion of the suspension part 2 is formed in one piece with one or more elements of the decorative part 3. It will however be understood that, for example to facilitate the manufacture of the panel 1, the lower portion of the suspension part 2 can be secured by fixing to one or more elements of the decorative part 3. It will also be understood that the fixing can be carried out by any means, for example by screwing, by gluing, by nailing, or by a combination of these.

[0086] Referring to the Figures 1 , 4a And 4c, it can be seen that the decorative part 3 is secured in a recess on 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 in 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.

[0087] The panel 1 is further configured such that a distance, in projection in the profile plane, between a bottom 4a of the clearance 4 and the distal end 211a 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 phase of mounting the panel from below the support profiles 120. According to a less preferred variant, the distance, in projection in the profile plane, between the bottom 4a of the clearance 4 and the distal end 211a of the first support projection 211 may be less than the spacing of said two flanges 121, 122.

[0088] Referring to the 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-lifting 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 second sole receiving space 222.

[0089] In addition, the anti-lifting projection 223 extends such that, in projection in the profile plane, a distal end 223a of the anti-lifting projection 223 is set back relative to 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-lifting projection 223 is greater than the spacing of said two soles 121, 122.

[0090] Furthermore, the anti-lifting projection 223 is configured to, in the state of the panel 1 suspended from said two soles 121, 122, be arranged 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-lifting projection 223 by elastic interlocking relationship between the anti-lifting projection 223 and the second sole 122.

[0091] Preferably, the anti-lift projection 223 is configured to be rigid and elastically deform the second sole 122 during the introduction of the second sole 122 into the second sole receiving space 222 by elastic fitting. Still preferably, the edges of the distal end 223a of the anti-lift projection 233 are beveled, or rounded, so as to facilitate the introduction and exit of the second sole 122 into the second sole receiving space 222 by elastic fitting.

[0092] According to variants of the invention, the anti-lift projection 223 may be configured to deform elastically during elastic fitting, such that elastic fitting 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 may for example be in the form of a lip made of flexible polymer, preferably rubber, slid into a fixing groove formed in the second suspension side 22.

[0093] As is best seen on the Figures 4a And 4c, in the panel 1 according to the first embodiment, the clearance 4 is configured such that the panel 1 further comprises 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-lifting projection 223, at an angle of 40 degrees relative to a horizontal axis, and therefore at an angle of 50 degrees relative to a vertical axis.

[0094] According to variants not shown, the panel 1 can be configured so that the guide face 7 extends obliquely at an angle of between 30 and 60 degrees.

[0095] The guide face 7 is configured to, during the assembly phase of the panel 1, guide the anti-lift projection 223 towards the second sole 122, by gravity. The guide face 7 is also configured to guide the anti-lift projection 223 towards the second sole 122, by gravity, when in use the second sole 122 accidentally leaves the second sole 222 receiving space, for example in the case of an impact from below the panel 1.

[0096] Referring to the Figures 1 , 4a et 4b , it can be seen that the panel 1 further comprises an abutment face 5. The abutment 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 bearing projection 211 towards a lower face of the panel 1.

[0097] The abutment face 5 defines, in projection in the profile plane, a lateral side of the first sole receiving space 212. Preferably, and as is better seen on the Figure 4b , the abutment face 5 is vertical. According to variants not shown, the abutment face 5 could extend obliquely.

[0098] 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.

[0099] The panel 1 according to the first embodiment further comprises, at 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 first sole plate receiving space 212. In the state of the panel 1 suspended from said two sole plates 121, 122, the masking portion 6 is configured to be arranged under the first sole plate 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 sole plates 121, 122.

[0100] If, in the state of the panel 1 suspended from said two soles 121, 122, a movement (vertical upward in use) is applied to the panel 1 in a direction from the decoration part 3 toward the suspension part 2, at the first suspension side 21, the masking portion 6 abuts against the first sole 121, such that the first sole 121 does not come out of the first sole receiving space 212.

[0101] In a variant not shown, a distance, in projection in 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 spacing of 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 going 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 which abuts against the first flange 121, such that the first flange 121 does not come out of the first flange receiving space 212.

[0102] This variant may, or may not, comprise a masking portion 6, configured to, in the state of the panel 1 suspended from said two soles 121, 122, be arranged under the first sole 121.

[0103] The length of the masking portion 6 is chosen as required to mask part or all of the first sole 121 from below the panel 1.

[0104] In panel 1 according to the first embodiment shown in the Figures 1 And 4a à 4c , the masking portion 6 extends beyond the first support projection 211, such that, in projection in the profile plane, the distal end 211a of the first support projection 211 is set back relative to the distal end 6a of the masking portion 6.

[0105] According to a variant represented in Figure 5a , the masking portion 6 extends to the first support projection 211, such that, in projection in the profile plane, the distal end 211a of the first projection 211 is aligned with the distal end 6a of the masking portion 6.

[0106] Furthermore, referring to the Figures 4a à 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 soles 121, 122, the arrangement of an acoustic slab D in a plenum above the panel 1.

[0107] According to variants not shown, the panel 1 can be configured to allow a user to place several acoustic tiles D, superimposed or arranged side by side, in the plenum.

[0108] There Figure 8 also shows 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.

[0109] With particular reference to the Figure 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-lifting 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.

[0110] 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, may extend over the entire space between the lateral sides 11 of the panel 1, for example by being carried by a crosspiece extending from one of the lateral sides 11 of the panel 1 to the other of the lateral sides 11.

[0111] Furthermore, in the first embodiment, the first support projection 211, the second support projection 221, the anti-lifting projection 223, the stop face 5, the masking portion 6, and the guide face 7, are formed in side members 2a extending from the first suspension side 21 to the second suspension side 22.

[0112] Furthermore, in the first embodiment of the panel 1, the panel 1 comprises two longitudinal members 2a arranged on the two lateral sides 11 of the panel 1. This configuration makes it possible in particular to improve the stability of the panel 1 in the state of the panel 1 suspended from said two flanges 121, 122, while limiting the weight of the panel 1. It will however be understood that the longitudinal members 2a could be brought closer to each other in the direction going from one lateral side 11 to the other lateral side 11. It will also be understood that, according to variants not shown, the panel 1 could comprise a greater number of longitudinal members 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-lifting 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 longitudinal members 2a.

[0113] Obviously, other technical solutions are possible for forming the first support projection 211, the second support projection 221, the anti-lifting projection 223, the abutment 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 possibly 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-lifting projection 223, a piece of the abutment face 5, a piece of the masking portion 6, or a piece of the guide face 7.

[0114] Furthermore, referring to the Figures 1 And 4aat 4c, it can be seen that, for the first embodiment of the panel 1, a lower portion of each spar 2a forms a counter batten 3a. In addition, the panel 1 further comprises a plurality of facing battens 3b fixed to the counter battens 3a. Advantageously, the facing battens 3b are fixed to the counter battens 3a in notches formed in lower faces of the counter battens 3a. In the first embodiment of the panel 1, the counter battens 3a and the facing battens 3b together form the decorative part 3.

[0115] As is best seen on the Figures 4a et 4b , in the first embodiment of the panel 1, one of the facing slats 3b of the plurality of facing slats 3b is configured to be fixed in line with the masking portion 6, such that, in the state of the panel suspended from said two soles 121, 122, said facing slat 3b is arranged in line with the first sole 121 and at least partially masks the latter.

[0116] If we refer to the Figure 1 , it can be seen that, in the first embodiment of the panel 1, the panel 1 further comprises a stiffener 3c arranged between two longitudinal members 2a, parallel to them, and configured to connect the facing slats 3b together. According to variants not shown, the panel 1 may comprise a greater number of stiffeners 3c and that each stiffener 3c is configured to connect at least two neighboring facing slats 3b together.

[0117] Furthermore, in the first embodiment shown in the Figures 1 And 4a à 4c , the side members 2a are spaced apart from each other in a direction from one lateral side 11 to the other lateral side 11. The side members 2a disposed closest to each of the lateral sides 11 are configured to be removably attached to the remainder of the panel 1. The decoration portion 3 of the remainder of the panel 1 is configured to be capable of being cut to length after one of the side members 2a configured to be removably attached is removed, and the removed side member 2a configured to be removably attached is configured to be reattached to the remainder of the panel 1 after the cutting to length is performed.

[0118] Thus, a dimension of the panel 1 in the direction going from one of the lateral sides 11 to the other of the lateral sides 11 is adjustable on site when installing a suspended false ceiling.

[0119] There Figure 9a presents a panel according to the first embodiment, before adjustment to size, and the Figure 9b shows the same panel 1, after adjustment to size in the direction from one lateral side 11 to the other lateral side 11. A panel 1 may in particular be prefabricated to be square, or may be prefabricated to be rectangular and configured to be adjusted to size on site to be square.

[0120] Alternatively, only one of the side members 2a arranged closest to the lateral sides 11 could be removably attached, so that the dimensional adjustment would necessarily be made on the side of the removably attached side member 2a.

[0121] 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, the panel 1 is configured to be able to be cut from one lateral side 11 to the other lateral side 11. During such cutting, 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 reformed, either by cutting into the panel 1 or by attaching an attachment or an insert. Figure 5a shows an example of the first side of the suspension recut in panel 1 and the Figure 5b shows an example of a second suspension side 22 reformed by an added piece. Alternatively, an L-type edge tab could replace the added piece, resting not on the sole 121 but on an additional profile.

[0122] Thus, the dimension of the panel 1 in the direction from the first suspension side 21 to the second suspension side 22 is adjustable on site when installing a suspended false ceiling.

[0123] In the first embodiment of panel 1, shown in the Figures 1 And 4a à 4c , the 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 lower faces of said two support profiles 120.

[0124] In addition, the panel 1 further comprises, on the second suspension side 22, an anti-lift stop 8 arranged at an interface between the lower portion of the suspension part 2 and the decorative part 3. The anti-lift stop 8 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 going 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-lift projection 223 in the second flange receiving space 222.

[0125] In the first embodiment of the panel 1, the anti-lift stop 8 is formed by a shoulder secured to the panel 1, the shoulder extending from the second suspension side 22 to the first suspension side 21. In addition, each side member 2a comprises an anti-lift stop 8.

[0126] 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, secured to the panel 1 at the level of the second suspension side 22.

[0127] The anti-lift stop 8 can also be secured 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, by gluing, by nailing, or by a combination of these.

[0128] 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. Furthermore, in the first embodiment of the panel 1, the stiffener 3c is arranged on the panel 1 so that, in the state of the panel 1 suspended from said two flanges 121, 122, it is arranged in line with 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.

[0129] The stiffener 3c can then have a function of masking the additional profile 130 to the right of which it is positioned.

[0130] One end of the stiffener 3c, on the second suspension side 22, may also have a function similar to the anti-lift 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 going 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-lift projection 223 in the second flange receiving space 222. According to a less preferred variant, the upper face of the stiffener 3c may be arranged below the upper face of the anti-lift stop 8.

[0131] The panel 1 according to the first embodiment can be used simply in combination with parallel support profiles 120, and that in this case, the stiffener 3c does not have a function of masking an additional profile 130 nor of abutment against an additional profile 130.

[0132] Furthermore, a panel 1 according to the first embodiment is preferably configured such that, in projection in the profile plane, a spacing between the first support projection 211 and the masking portion 6 is greater than a spacing between the second support projection 221 and the anti-lifting projection 223.

[0133] This configuration makes it possible in particular to slide two soles into the first sole receiving space 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 sole of a support profile 120 fixed to the wall, in addition to the first sole 121 of a support profile 120 suspended from the ceiling.

[0134] There Figure 2 presents 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 comprises an anti-lift stop 8 and that the panel 1' according to the second embodiment does not comprise an anti-lift stop 8.

[0135] The second embodiment of the panel 1' may be preferred, in particular because it makes it possible to obtain a panel 1' which is lighter and less expensive than the first embodiment.

[0136] In reference to the Figures 6a à 6c , we will now briefly describe a method of mounting a panel 1 according to the invention on two support profiles 120, from below the support profiles 120, and a method of dismantling the panel 1 from below the support profiles 120.

[0137] There Figure 6a presents a phase of mounting a panel 1 on two support profiles 120.

[0138] The method of mounting the panel 1 comprises the steps of: tilting the panel 1, and placing the bottom 4a of the clearance 4 in abutment against the distal end 122a of the second sole 122; lifting the first suspension side 21, so that the first support projection 211 is located above the first sole 121; shifting the panel 1 towards the first sole 121 to slide the first sole 121 into the first sole receiving space 212; and pulling on the second suspension side 22, so as to house the second sole 122 in the second sole receiving space 222, by elastic interlocking relationship between the anti-lift projection 223 and the distal end 122a of the second sole 122.

[0139] There Figure 6b shows the panel 1 in a state mounted on the two support profiles 120 and suspended from said two soles 121, 122.

[0140] There Figure 6c presents a dismantling phase of panel 1.

[0141] The method of dismantling panel 1 comprises the steps of: pushing on the first suspension side 21, so as to release the second sole 122 from the second sole receiving space 222, by elastic deformation between the second sole 122 and the anti-lifting projection 223; tilting the panel 1, and shifting the panel 1 towards the second sole 122, so as to put the distal end 122a of the second sole 122 in abutment against the bottom 4a of the clearance 4 and to slide the first sole 121 out of the first sole receiving space 212; and lowering and recovering the panel 1.

[0142] The present invention also relates to a kit for a panel 1 according to the invention.

[0143] The kit comprises a suspension part 2 and a decoration part 3 configured to be assembled together. The suspension part 2 and the decoration part 3 may be configured to be assembled by any means, for example by screwing, by gluing, by nailing, or by a combination thereof.

[0144] The present invention also relates to a suspended false ceiling system 100.

[0145] If we refer to the Figures 7a, 7b And 8 , it can be seen that a suspended false ceiling system 100 according to an embodiment of the invention is represented therein, comprising support profiles 120 configured to be suspended from a ceiling in a parallel manner, and panels 1 according to the invention.

[0146] In the embodiment illustrated in the Figures 7a, 7b And 8 , the system 100 comprises panels 1 according to the first embodiment shown in the Figure 1 . According to variants, the system 100 could however comprise panels 1' according to the second embodiment shown in the Figure 2 , or according to another variant of the invention.

[0147] Similar to an existing suspended false ceiling, the support profiles 120 are configured to be suspended from the ceiling of a building in which the suspended false ceiling system 100 is intended to be installed. The support profiles 120 disposed at the periphery, or edge, of the suspended false ceiling system 100 are thus preferably configured to be fixed to walls of the building rather than suspended from the ceiling.

[0148] The support profiles 120 may be suspended at a distance from the ceiling using cables, rods, or similar means. The support profiles 120 may be fixed to the walls by screwing, gluing, or any other means.

[0149] 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 as required to obtain the desired surface area for the suspended false ceiling system 100.

[0150] The support profiles 120 may simply be arranged parallel to each other. However, preferably, the support profiles 120 are arranged to form a support frame 110. The Figure 3 presents an example of a support frame 110 of a suspended false ceiling system 100 according to the invention.

[0151] Referring to the 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.

[0152] According to the invention, each support profile 120 has a cross-section at least partially in the shape of an "L" and comprises at least one sole 121, 122 formed on the ground side by the crosspiece of the "L". The system 100 is further configured such that the soles 121, 122 are parallel and coplanar.

[0153] 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 support profiles 120 and inverted "T" shaped support profiles 120.

[0154] In particular, the support profiles 120 configured to be suspended from the ceiling of the building are preferably inverted "T" shaped, while the support profiles 120 intended to be fixed to the walls of the building are preferably "L" shaped.

[0155] Typically, a suspended ceiling system support frame includes sections called "bearers" that are configured to be attached to the building structure, sections called "main struts" that are configured to extend perpendicular to the bearers and be attached to them, and sections called "secondary struts" that are configured to extend perpendicular to the main struts and be attached to them. The secondary struts are therefore parallel to the bearers.

[0156] According to the embodiment shown in the Figures 3 , 7a , 7b And 8, the support profiles 120 are main struts, and the additional profiles 130 are carriers and secondary struts. It will be understood, however, that, according to variants not shown, the support profiles 120 could be carriers, secondary struts, or a combination thereof. In this case, the panels 1 would be rotated 90 degrees with respect to what is shown in the Figures 7a, 7b And 8 .

[0157] The support profiles 120 and the additional profiles 130 can also, for example, be of type T24.

[0158] Furthermore, each panel 1 of the system 100 is configured to be arranged in a mounting space defined between two parallel and coplanar soles 121, 122 of said support profiles 120, and is configured to be suspended from said two soles 121, 122 using the suspension part 2.

[0159] 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.

[0160] According to an advantageous embodiment of the system 100, the first panel 1 comprises a masking portion 6, and the masking portion 6 of the first panel 1 is configured to, when the first panel 1 and the second panel 1 are suspended from the support profiles 120, extend at least partially in line with the second support projection 221 of the second panel 1.

[0161] 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 one panel 1 does not interfere with the first suspension side 21 of another panel 1 arranged in series.
