Description

Title of the invention: WOODEN CLADDING BOARD Technical field of the invention

[0001] The present invention relates to the general field of wall and partition cladding of a building. More specifically, it relates to a wooden cladding board. State of the art

[0002] In the field of wall and partition cladding for a building, it is known to use cladding boards, also referred to as "cladding planks", having the following functions: - improving the protection of the building's walls and partitions against weathering and impacts, - improving the thermal and / or acoustic insulation of the building, and - improving the aesthetic appearance of the building.

[0003] Cladding boards are fixed horizontally to walls and partitions in most cases, and according to different fixing methods: - either directly onto the masonry: bricks, concrete, or - either on a wooden or metal frame fixed to said masonry.

[0004] As indicated above, the cladding boards are mostly fixed horizontally, but they can also be fixed vertically or obliquely, however this requires respecting the direction of the wood fibers in order to promote the natural flow of rainwater, and to avoid creating so-called "trapping" areas which prevent the natural flow of rainwater.

[0005] It is precisely these trapping zones that are one of the main causes of damage to wood cladding. Indeed, in these trapping zones, the natural flow of rainwater does not occur easily or at all; the rainwater is then trapped and absorbed by the wood of the cladding boards, which results in the cladding boards swelling and causing mechanical deterioration such as cupping or warping.

[0006] Exposure of the building's walls and partitions to the sun can also cause mechanical deterioration of the cladding boards due to the expansion of each cladding board.

[0007] This phenomenon of mechanical deterioration is accentuated by the fact that each cladding board is fixed directly or indirectly to the walls and partitions of the building and is at least partially embedded in adjacent cladding boards.

[0008] Similarly, cladding boards, which have dried during intense exposure to the sun, can also swell during a humid period, the wood in particular absorbing moisture from the air.

[0009] Finally, the swelling or expansion of the cladding boards not only results in the mechanical deterioration of said cladding boards, but also in harming the aesthetic appearance of the entire cladding. Summary of the invention

[0010] The object of the present invention is to provide a wooden cladding board arranged to be fixed directly or indirectly to the walls and partitions of the building by being fitted at least in part into adjacent upper and lower cladding boards, said cladding board being simple to implement and manufacture, and allowing to optimally position said cladding board in relation to the adjacent cladding boards during the assembly of the cladding, to limit at least in part the phenomenon of mechanical deterioration, and to guarantee the aesthetic appearance of the whole cladding.

[0011] According to the invention, a wooden cladding board is therefore proposed, arranged to be fixed directly or indirectly to the walls and partitions of a building by being fitted into adjacent lower and / or upper cladding boards, comprising a plate in the general shape of an elongated parallelepiped having at least one lower edge having a longitudinal groove, and an upper edge having a substantially vertical longitudinal tongue provided with at least two rear and front sides, notable in that it has a longitudinal rim extending substantially horizontally from the rear side of said tongue towards the outside of said cladding board,said edge defining a bearing area for an adjacent upper cladding board and being dimensioned to break and detach from said upper edge under the action of a predetermined mechanical force generated by a relative displacement between the tongue of the cladding board and the groove of the adjacent upper cladding board.

[0012] Advantageously, said groove is provided with at least two rear and front walls inclined so as to form an acute angle A between them.

[0013] Similarly, the two rear and front sides of the tongue are inclined so as to form between them an angle whose value is at most equal to the value of said angle A between the two rear and front walls of the groove.

[0014] According to a particular embodiment, the upper end of said upper edge has a cross-section in the general shape of a triangle. Brief description of the figures

[0022] With reference to figures 1 to 3, the invention relates to a cladding board 1 arranged to be fixed, advantageously horizontally, directly or indirectly on walls and / or partitions of a building by being fitted at least in part into adjacent cladding boards 1' (partially shown in figures 4 to 6), the walls and / or partitions and the building not being shown in the figures in order not to overload them.

[0023] It goes without saying that the cladding blade 1 can also be fixed vertically or obliquely without going out of the scope of the present invention, terms such as, for example, horizontal, lower vertical or even upper will then have to be adapted.

[0024] The cladding blade 1,1' according to the invention comprises a plate 2 in the general shape of an elongated parallelepiped having at least a substantially vertical front face 3, a rear face 4 substantially parallel to said front face 3, a lower edge 5 and an upper edge 6.

[0025] Herein, "rear" means any element or part of an element of the cladding blade 1,1' according to the invention disposed on the side of the walls or partitions of the building receiving said cladding blade 1,1', and "front" means any element or part of an element of the cladding blade 1,1' disposed on the side opposite said walls or partitions.

[0026] To ensure the interlocking between the cladding boards 1,1' according to the invention, the lower edge 5 of the cladding board 1 is able to cooperate with the upper edge of the lower adjacent cladding board, i.e. placed below said cladding board 1, and the upper edge 5 of the cladding board 1 is able to cooperate with the lower edge 5' of the upper adjacent cladding board 1', i.e. placed above said cladding board 1.

[0027] It is understood that, depending on the configuration of the assembly, the cladding blade 1 can be fitted into one or more lower adjacent cladding blade(s) and / or one or more upper adjacent cladding blade(s).

[0028] According to a particular embodiment of the invention, the lower edge 5 of the cladding board 1 has a longitudinal groove 51 provided with at least rear walls 52 and front walls 53, and the upper edge 6 of said cladding board 1 has a substantially vertical longitudinal tongue 61 provided with at least two rear sides 62 and front sides 63.

[0029] Here, "substantially horizontal" and "substantially vertical" refer to any element or part of an element of the cladding blade 1 according to the invention making an angle with the horizontal and vertical respectively between -15° and +15°.

[0030] Similarly, herein we designate by "substantially parallel(s)" and by "substantially perpendicular(s)" elements or parts of elements of the cladding blade 1 according to the invention making an angle between them respectively between -15° and +15°, and between 75° and 105°.

[0031] Advantageously, said groove 51 is slightly flared and its two rear walls 52 and front walls 53 are inclined so as to form an acute angle A between them.

[0032] Similarly, the two rear sides 62 and front sides 63 of the tongue 61 are advantageously inclined so as to form between them an angle whose value is preferably at most equal to the value of said angle A between the two rear and front walls 52,53 of the groove 51 of the lower edge 5.

[0033] In addition, the upper end 64 of said upper edge 6 advantageously has a cross-section in the general shape of a triangle, preferably isosceles.

[0034] With reference to figures 4 and 5, it is clear that this configuration makes it possible in particular to limit the contact area between the lower and upper edges of two adjacent cladding boards and thus avoid any jamming between said lower and upper edges.

[0035] Furthermore, it is clear that the pointed shape of the end 64 of the tongue 61 of the upper edge 6 of the cladding board 1 facilitates the insertion of said tongue 61 into the groove 51' of the lower edge 5' of the adjacent upper cladding board 1' and therefore the placement of the latter.

[0036] In addition, to allow optimal positioning during the assembly of the cladding boards, the upper edge 6 of each cladding board 1 also has a longitudinal rim 65 extending substantially horizontally from its rear side 62 towards the outside of said cladding board 1.

[0037] With reference to Figures 4 and 5, it is clear that the edge 65 of the upper edge 6 of each cladding board 1 defines a bearing area on which comes resting the upper adjacent cladding blade 1' allowing optimal positioning when fitting the latter onto the cladding blade 1 for mounting the cladding on a wall or partition of a building.

[0038] Indeed, to cover a wall or partition of a building with cladding, one proceeds, for example, in the following manner: - A cladding board 1 is fixed to the wall or partition, generally starting from the bottom of said wall or partition, - a cladding board 1' is positioned adjacent to and above cladding board 1 (see [Fig. 4]), and - we lower said adjacent cladding board 1' to insert the tongue 61 of the upper edge 6 of cladding board 1 into the groove 51' of the lower edge 5' of cladding board 1' until said lower edge 5' comes to rest against the edge 65 of the upper edge 6 of said cladding board 1 (Cf. [Fig.5]), and so on with the other adjacent cladding boards placed above.

[0039] It goes without saying that, in order to cover a wall or partition of a building with cladding, one can also start by fixing the cladding board 1 placed at the very top of the wall or partition, without going out of the scope of the present invention.

[0040] Advantageously, said rim 65 of the upper edge 6 of each cladding board 1 is positioned so that, when the lower edge 5' of the adjacent cladding board 1' is in contact with said rim 65, there remains, between said tongue 61 and groove 51' (Cf. [Fig.5]), a residual gap which is particularly interesting for reasons which will be developed later.

[0041] Furthermore, with reference to [Fig.6], said edge 65 of the upper edge 6 of each cladding board 1 is dimensioned to break so as to detach from said upper edge 6 under the action of a predetermined mechanical force generated by a relative displacement between the tongue 61 of the upper edge 6 of the cladding board 1 and the groove 51' of the lower edge 5' of the adjacent cladding board 1', this relative displacement being due to a swelling or dilation of the cladding board 1 and / or the adjacent cladding board 1'.

[0042] Here, "relative displacement between..." refers to the fact that, when the lower edge 5' of the upper adjacent cladding board 1' is in contact with the rim 65 of the upper edge 6 of the cladding board 1 (See [Fig.5]), either only the tongue 61 moves towards the groove 51' which remains stationary, or only the groove 51' moves towards the tongue 61 which remains stationary, or the tongue 61 and groove 51' move towards each other.

[0043] A person skilled in the art will have no difficulty in determining the value of the force generated by a relative displacement between the tongue 61 of the upper edge 6 of the cladding board 1 and the groove 51' of the lower edge 5' of the cladding board 1' adjacent. Furthermore, depending on the value of the force generated, the person skilled in the art will be able to determine the dimensions of the edge 65 adapted to allow the break and detachment of the latter from the upper edge 6 of the cladding board 1, depending in particular on the type of wood of said cladding board 1.

[0044] It is understood that the breaking of said edge 65 of the upper edge 6 of each cladding board 1 allows the relative movement of the tongue 61 of the upper edge 6 of the cladding board 1 and of the groove 51' of the lower edge 5' of the adjacent cladding board 1' to continue without risk of deformation and / or warping of the cladding boards 1,1', which has the effect of not damaging the cladding boards 1,1' and thus preserving the aesthetic appearance of the cladding.

[0045] Moreover, it is clear that this relative displacement is further facilitated by the presence of the residual play, previously described, between said tongue 61 and groove 51'.

[0046] In addition, the end 64 of the tongue 61 of the upper edge 6 of the cladding board 1 allows, by virtue of its pointed shape, a compression of the wood and therefore an absorption of any additional dimensional variation of said cladding board 1, when its tongue 61 comes into contact with the bottom of the groove 51' of the lower edge 5' of the adjacent cladding board 1'.

[0047] The cladding blade 1,1' according to the invention is more particularly applicable to the covering of the walls and / or partitions of a building by being fixed and fitted into adjacent cladding blades horizontally, but it goes without saying that said cladding blade 1,1' can be adapted to be fixed and fitted vertically or obliquely.

[0048] Finally, it goes without saying that the examples of cladding blade 1,1' conforming to the invention which have just been described are only particular illustrations, in no way limiting of the invention.
