Description

Title of the invention: Facing system, intended to be attached to a support, for example a wall or a floor Technical field of the invention

[0001] The present invention relates to the technical field of facing systems, intended to be attached to a support, for example a wall or a floor. State of the art

[0002] For the facing of a support, for example a wall or a floor, certain facing systems include:

[0003] - joists, intended to be secured to the support, parallel to each other compared to others,

[0004] - facing blades, consisting of profiles which are intended to be joined parallel to each other, with at least two joists juxtaposed and oriented perpendicular to these joists.

[0005] The assembly of the joists and the facing slats is generally carried out by means of interface members.

[0006] However, current cladding systems are not entirely satisfactory in terms of simplifying assembly operations or, if necessary, in terms of the possibility of replacing cladding slats (for example in the event of deterioration). Presentation of the invention

[0007] In order to overcome the aforementioned drawback of the state of the art, the present invention proposes a facing system, intended to be attached to a support, for example a wall or a floor, comprising:

[0008] - joists, intended to be secured to said support, parallel to the relative to each other,

[0009] - facing blades, consisting of profiles which are intended to be joined parallel to each other, with at least two joists juxtaposed and oriented perpendicular to said joists, and

[0010] - interface members, intended to be interposed between said joists and said facing blades,

[0011] which interface members comprise:

[0012] - a base, intended to be secured to a joist and

[0013] - at least one receiving location adapted to receive a facing blade,

[0014] And, according to the invention, the facing blades and said at least one location for receiving said interface members comprise means of assembly by de- elastic formation.

[0015] Such a structure is thus particularly simplified in terms of assembly and disassembly operations.

[0016] The interface members can also be of interest for avoiding friction between the facing slats and the joists, in particular when the latter are made of metallic material (avoiding metallic friction noises).

[0017] Other non-limiting and advantageous characteristics of the product according to the invention, taken individually or in all technically possible combinations, are the following:

[0018] - said joists comprise at least one longitudinal groove for the posi operation of the base of said interface members, advantageously in series along the length of said longitudinal groove; preferably, the joists have a rectangular section comprising four sides each provided with at least one longitudinal groove for positioning the base of said interface members; more preferably, the joists have two short sides and two long sides, and at least one of said long sides has two parallel longitudinal grooves;

[0019] - the assembly means by elastic deformation consist of two pairs of flaps, male and female, which are distributed over said facing slats and said at least one receiving location of said interface members and which cooperate by fitting together by elastic deformation; preferably, the flaps comprise straight teeth, cooperating by fitting together by elastic deformation; preferably, the straight teeth of each flap comprise at least two teeth; more preferably, the receiving location of said interface members comprises a pair of female flaps and the facing slats comprise a pair of male flaps; more preferably, at least one of the flaps comprises a tab adapted to facilitate its separation and to facilitate the dissociation of the assembly means by elastic deformation;

[0020] - the joists, the facing slats and the interface members consist of profiles;

[0021] - the joists and the facing slats are made of metallic material and that the interface organs are made of plastic material.

[0022] The present invention also relates to a support equipped with a facing system according to the invention, comprising:

[0023] - said joists, secured to said support, parallel to each other by in relation to others,

[0024] - said facing blades, which are secured in parallel to each other by relation to the others, with at least two joists juxtaposed and oriented perpendi- cularly to the said joists, and

[0025] - said interface members, interposed between said joists and said blades of facing.

[0026] Of course, the various features, variants and embodiments of the invention may be combined with each other in various combinations to the extent that they are not incompatible or mutually exclusive. Detailed description of the invention

[0027] Furthermore, various other characteristics of the invention emerge from the appended description given with reference to the drawings which illustrate non-limiting forms of embodiment of the invention and where:

[0028] [Fig-1] is a partial schematic and perspective view of a system of facing according to the invention;

[0029] [Fig.2] is a partial view of the facing system according to [Fig.l], according to a side view oriented perpendicular to the joists;

[0030] [Fig.3] is a partial view of the cladding system according to [Fig.l], according to a side view oriented perpendicular to the cladding slats;

[0031] [Fig.4] is a partial and enlarged view of [Fig.3], illustrating in more detail the section of a facing blade and its interface member;

[0032] [Fig.5] is also a partial view of the facing system according to [Fig.l], according to a section plane oriented perpendicular to the joists, in which said joist is arranged according to another orientation adapted to receive here two interface members juxtaposed within two parallel longitudinal grooves.

[0033] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0034] The facing system 1 according to the invention is intended to be attached to a support S.

[0035] For example, this facing system 1 consists of:

[0036] - a facing system 1 for covering a support S formed by a wall (usually vertical), or

[0037] - a facing system 1 for covering a support S formed by a floor (usually horizontal), for example a terrace, as illustrated in [Fig.l] in particular.

[0038] Generally speaking, such a facing system 1 comprises:

[0039] - joists 2, intended to be secured to the support S, parallel to the relative to each other,

[0040] - facing blades 3, intended to be joined in parallel to each other compared to the others, with at least two joists 2 juxtaposed and oriented per- pendicularly to these joists 2, and

[0041] - interface members 4, intended to be interposed between the joists 2 and the 3 facing blades.

[0042] Generally speaking, according to the invention, the facing blades 3 and the interface members 4 comprise elastic deformation assembly means 5 (also called “elastic deformation interlocking means” or “elastic interlocking means”).

[0043] As developed below, such a technical solution is particularly interesting for facilitating the assembly and disassembly of the facing blades 3 relative to the interface members 4. Joists

[0044] Generally speaking, the joists 2 advantageously consist of profiles.

[0045] The joists 2 are preferably made of metallic material, for example aluminum.

[0046] Still generally, the joists 2 advantageously comprise at least one longitudinal groove 21 (at the level of their external surface) for the positioning of a base 41 of the interface members 4.

[0047] This longitudinal groove 21 is advantageously adapted to receive a plurality of interface members 4, in series along the length of said longitudinal groove 21 ([Fig.3] in particular).

[0048] Such a longitudinal groove 21 advantageously extends continuously along the length of the joist 2.

[0049] According to the illustrated embodiment, the joists 2 have a rectangular section comprising four sides 2a each provided with at least one longitudinal groove 21 for positioning the base 41 of the interface members 4 ([Fig.2]).

[0050] Each side 2a is here formed by a peripheral wall 2b.

[0051] In this case, the joists 2 have two small sides 2al and two large sides 2a2.

[0052] And at least one of the large sides 2a2 has two parallel longitudinal grooves 21.

[0053] These two longitudinal grooves 21 are advantageously juxtaposed over the width of said at least one large side 2a2.

[0054] Preferably, a first large side 2a2 comprises two longitudinal grooves 21. And a second large side 2a2 comprises a single longitudinal groove 21, advantageously centered on its width.

[0055] Preferably, the short sides 2al comprise a longitudinal groove 21, centered on their width.

[0056] For example, the dimensions of a joist 2 are as follows:

[0057] - a length ranging from 2 to 5 m,

[0058] - a width dimension of a small side 2al ranging from 30 to 50 mm,

[0059] - a width dimension of a large side 2a2 ranging from 50 to 100 mm.

[0060] For example, the dimensions of a longitudinal groove 21 are as follows:

[0061] - a width dimension ranging from 20 to 40 mm,

[0062] - a depth rating ranging from 1 to 5 mm. The facing blades

[0063] Generally speaking, the facing blades 3 advantageously consist of profiles.

[0064] The facing slats 3 are preferably made of metallic material, for example aluminum. According to another embodiment, the facing slats 3 could be made of wood or composite material.

[0065] The facing blades 3 advantageously form:

[0066] - wall blades, for covering a wall, or

[0067] - floor blades, for example terrace blades.

[0068] Again in general, as illustrated in [Fig.4], the facing blades 3 advantageously comprise:

[0069] - a frontal spar 31, forming the facing itself, and

[0070] - an assembly structure 32, for its assembly with a location of reception 42 of an interface member 4.

[0071] Preferably, the spar 31 comprises a first, rear face 311, which carries the assembly structure 32.

[0072] The assembly structure 32 advantageously comprises a part of the elastic deformation assembly means 5, developed subsequently.

[0073] Preferably, the first front face 311 also comprises support legs 37, which come to bear on a facing structure, in particular on the joists 2 and / or the interface members 4. Interface organ

[0074] Generally speaking, the interface members 4 advantageously consist of profiles.

[0075] The interface members 4 are advantageously made of a plastic material, advantageously a reinforced polymer, for example chosen from polyethylene, polypropylene, polyamide, etc.

[0076] Still generally, the interface members 4 comprise:

[0077] - a base 41, intended to be secured to a joist 2, and

[0078] - at least one receiving location 42 adapted to receive a facing blade 3.

[0079] Preferably, a base 41 is in the form of a rectangular plate, of which:

[0080] - a first front face 411, before, carries said at least one location of reception 42, and

[0081] - a second front face 412, rear, is intended to bear on a joist 2.

[0082] Preferably, the first front face 411 is adapted to serve as a bearing surface for the associated facing blade 3.

[0083] Preferably, this first front face 411 is offset, projecting, relative to the associated side 2a. In other words, the thickness of the base 41 is greater than the depth of the longitudinal groove 21.

[0084] This configuration has the advantage of avoiding contact between the facing blade 3 and the joist 2, which eliminates any possible friction noise between the latter (in particular metal / metal).

[0085] Generally speaking, preferably, the width dimension of the base 41 corresponds, apart from the clearance, to the width of a longitudinal groove 21 formed on the joists 2.

[0086] The connection of a base 41 with a joist 2 is for example obtained by a screw member attached through this base 41 (through its first front face 411 and its second front face 412) and implanted in the joist 2.

[0087] As developed below, said at least one receiving location 42 of the interface members 4 comprises a part of the elastic deformation assembly means 5. Means of assembly by elastic deformation

[0088] According to the invention, the facing blades 3 and said at least one receiving location 42 of the interface members 4 comprise the elastic deformation assembly means 5 (also called “clipping assembly means”).

[0089] In this case, these elastic deformation assembly means 5 are formed by:

[0090] - the assembly structure 32 of the facing blades 3, and

[0091] - said at least one receiving location 42 of the interface members 4.

[0092] Preferably, the elastic deformation assembly means 5 consist of two pairs of flaps 35, 45, male and female, which are distributed over the facing blades 3 and said at least one receiving location 42 of the interface members 4.

[0093] In other words, the facing blades 3 comprise a first pair of flaps 35 and said at least one receiving location 42 of the interface members 4 comprises a second pair of flaps 45.

[0094] In particular, the flaps 35 of the facing blades 3 extend longitudinally, along the length of these facing blades 3.

[0095] These flaps 35 of the facing blades 3 advantageously extend perpendicularly relative to the first front face 311.

[0096] And the flaps 45 of the interface members 4 advantageously extend transversely, over the width of the base 41.

[0097] These flaps 45 of the interface members 4 advantageously extend perpendicularly relative to the first front face 411 of the base 41.

[0098] In other words, the flaps 45 of the interface members 4 are intended to extend perpendicularly relative to the joists 2.

[0099] These two pairs of flaps 35, 45 cooperate by interlocking by elastic deformation.

[0100] For this, the flaps 35, 45 comprise straight teeth 351, 451, cooperating by interlocking by elastic deformation.

[0101] Preferably, the straight teeth 351, 451 of each flap 35, 45 comprise at least two teeth 351, 451.

[0102] In this case, the receiving location 42 of the interface members 4 comprises a pair of female flaps 45 and the facing blades 3 comprise a pair of male flaps 35.

[0103] In other words, during assembly, the flaps 35 of a facing blade 3 are housed here (are sandwiched) between the flaps 45 of the interface members 4.

[0104] Preferably, as illustrated in [Fig. 4], at least one of the flaps 45, here the flaps 45 of the interface members 4, comprises a tab 46 adapted to facilitate its separation and to facilitate the dissociation of the assembly means by elastic deformation 5.

[0105] This tab 46 extends here from the free edge of the flaps 45, in overhang. Assembly

[0106] In practice, the joists 2 are secured to a support S, parallel to each other.

[0107] The spacing between the joists 2 is for example 40 to 60 cm.

[0108] The parallelism of the joists 2 is advantageously ensured by spacers 7 (illustrated schematically in [Fig.l]).

[0109] The spacers 7 are for example made up of sections of joists 2 which are oriented at right angles.

[0110] A section of joist 2, forming a spacer 7, can be secured to a joist 2 by means of angle irons which are secured within their adjoining longitudinal grooves 21.

[0111] At least two lateral joists 2 are provided to receive the ends of the facing slats 3. At least one intermediate joist 2 may be provided between the side joists 2, in particular to prevent bending of the facing slats 3.

[0112] In particular, the joists 2 are advantageously oriented according to the desired longitudinal groove(s) 21.

[0113] For example, the joists 2 are oriented so as to expose:

[0114] - a large side 2a2 comprising a single longitudinal groove 21 ([Fig.2] in particular), for example for the edges of the cladding system 1, or

[0115] - a large side 2a2 comprising the two longitudinal grooves 21 ([Fig.5] in particular), for example for the alignment of facing slats 3, or

[0116] - a small side 2a 1 comprising a single longitudinal groove (orientation not re presented), for example to separate the facing blades 3 from the support S.

[0117] The interface members 4 are then attached and secured to the joists 2, advantageously within the longitudinal grooves 21.

[0118] The interface members 4 are advantageously aligned in series, distributed along the length of the joists 2 ([Fig.3]).

[0119] The facing blades 3 are then attached to these interface members 4.

[0120] These facing blades 3 are reported parallel to each other in relation to the others and perpendicular to the joists 2.

[0121] This final assembly is obtained here by the elastic interlocking of the assembly means by elastic deformation 5.

[0122] In particular, the flaps 35 of the facing blades 3 are housed here, by plastic interlocking, between the flaps 45 of the interface members 4.

[0123] Following this assembly, a support S is thus obtained equipped with a facing system 1 according to the invention, comprising:

[0124] - the joists 2, secured to the support S, parallel to each other in relation to others,

[0125] - the facing blades 3, which are secured in parallel to each other by relative to the others, with at least two joists 2 juxtaposed and oriented perpendicular to said joists 2, and

[0126] - the interface members 4, interposed between the joists 2 and the facing slats 3.

[0127] If necessary, the facing blades 3 can advantageously be removed relative to their interface members 4.

[0128] To facilitate this removal, it is possible here to exert a force on the tab 46 aimed at inactivating the interlocking means by elastic deformation 5.

[0129] Of course, various other modifications may be made to the invention within the scope of the appended claims.
