Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne le domaine des revêtements de sol et plus particulièrement une dalle pour revêtements de sol, du type en forme de parallélogramme et comprenant sur les quatre côtés des moyens d'assemblage mâle en saillies en complémentarité d'assemblage avec des moyens d'assemblage femelle définis entre deux moyens d'assemblage mâle, permettant une pose des dalles sans qu'il soit nécessaire de visualiser le détrompeur visuel imprimé ou gravé sur la face inférieure de la dalle.The present invention relates to the field of floor coverings and more particularly to a floor covering slab, of the parallelogram-like type and comprising on all four sides male assembly means projecting in complementarity with assembly means female assembly defined between two male assembly means, allowing laying of the slabs without the need to visualize the visual key printed or engraved on the underside of the slab.

ART ANTERIEURPRIOR ART

Dans le domaine des revêtements de sol, il est bien connu des dalles de revêtement de sol de forme carré ou rectangulaire comprenant sur ses quatre côtés de moyens d'assemblage mâle et/ou femelle coopérant avec des moyens d'assemblage complémentaires femelle et/ou mâle d'une dalle adjacente.In the field of floor coverings, it is well known square or rectangular floor covering slabs comprising on its four sides male and / or female assembly means cooperating with complementary female assembly means and / or male of an adjacent slab.

De telles dalles sont notamment représentées sur les figures 1 et 2. Chaque dalle (1) présente une forme de carré qui comprend sur les quatre côtés des moyens d'assemblage mâle (2) en saillies en complémentarité d'assemblage avec des moyens d'assemblage femelle (3) définis entre deux moyens d'assemblage mâle (2). Ces moyens d'assemblage mâle (2) et femelle (3) présentent une forme générale de trapèze et plus particulièrement de queue d'aronde dont les arrêtes sont arrondies. Les quatre côtés de la dalle (1) sont strictement identiques de sorte que, lors de l'assemblage n'importe quel côté d'une dalle (1) peut être assemblé à l'un quelconque des côtés d'une dalle (1) adjacente.Such slabs are particularly represented on Figures 1 and 2 . Each slab (1) has a square shape which comprises on all four sides male assembly means (2) projecting complementary assembly with female assembly means (3) defined between two male assembly means (2). These male (2) and female (3) assembly means have a general shape of trapezium and more particularly of dovetail whose edges are rounded. The four sides of the slab (1) are strictly identical so that when joining any side of a slab (1) can be assembled to any of the sides of a slab (1) adjacent.

Ces dalles sont posées flottantes et comportent, usuellement, un décor teinté dans la masse de sorte qu'il est nécessaire de poser lesdites dalles suivant un sens de pose défini afin que le décor soit homogène sur toute la surface posée. A cet effet, un détrompeur visuel (4), en référence aux figures 1 et 2, présentant la forme d'une flèche indiquant le sens de pose est gravé ou imprimé sur la face inférieure de chaque dalle (1). Lors de la pose, l'opérateur doit préalablement retourner la dalle (1) pour connaître le sens de pose de ladite dalle (1) ce qui grève considérablement le temps de pose et, in fine, le coût de la pose du revêtement de sol. Par ailleurs, malgré la présence du détrompeur visuel (4), une erreur sur le sens de la pose d'une ou plusieurs dalles peut arriver. De plus, le détrompeur visuel de la face inférieure des dalles peut être effacé ce qui peut être source d'une erreur de pose.These slabs are placed floating and usually comprise a tinted decor in the mass so that it is necessary to put said slabs in a defined laying direction so that the decor is homogeneous over the entire surface. For this purpose, a visual keying device (4), with reference to Figures 1 and 2 , in the form of an arrow indicating the Laying direction is engraved or printed on the underside of each slab (1). When laying, the operator must first return the slab (1) to know the direction of laying of said slab (1) which significantly affect the exposure time and, ultimately, the cost of laying the flooring . Moreover, despite the presence of the visual key (4), an error on the direction of laying one or more slabs can happen. In addition, the visual keying of the lower face of the slabs can be erased which can be a source of a laying error.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'un des buts de l'invention est donc de remédier à ces inconvénients en proposant une dalle de revêtement de sol de conception simple et peu onéreuse, permettant une pose rapide et aisée et procurant un sens de pose unique de sorte qu'il ne soit plus nécessaire d'utiliser un détrompeur visuel pour déterminer le sens de pose.One of the aims of the invention is therefore to overcome these disadvantages by providing a flooring slab of simple and inexpensive design, allowing a quick and easy installation and providing a single direction of installation so that it does not it is no longer necessary to use a visual keying device to determine the direction of installation.

A cet effet et conformément à l'invention, il est proposé une dalle pour revêtements de sol, du type en forme de parallélogramme et comprenant sur les quatre côtés des moyens d'assemblage mâle en saillies en complémentarité d'assemblage avec des moyens d'assemblage femelle définis entre deux moyens d'assemblage mâle, les moyens d'assemblage mâle (2) étant identiques sur les quatre côtés de la dalle (1) ; ladite dalle est remarquable en ce que les moyens d'assemblage mâle de deux côtés opposés de la dalle sont décalés entre eux d'un demi pas et en ce que les moyens d'assemblage mâle de deux côté adjacents sont décalés entre eux d'une valeur non nulle et différente d'un demi pas ou d'un pas, ou un de leur multiple, ledit pas correspondant à la distance entre la crête de deux moyens d'assemblage mâle adjacent d'un même côté de la dalle, de sorte que les moyens d'assemblage de l'un des côtés d'une dalle n'est susceptible de s'emboiter avec les moyens d'assemblage femelle que d'un seul côté d'une dalle adjacente sans qu'il y ait de décalage entre les bords des deux dalles adjacentes.For this purpose and in accordance with the invention, there is provided a slab for floor coverings, of the parallelogram-like type and comprising on all four sides male assembly means projecting in complementarity of assembly with means of female assembly defined between two male assembly means, the male assembly means (2) being identical on the four sides of the slab (1); said slab is remarkable in that the male assembly means of two opposite sides of the slab are offset from each other by half a step and in that the male assembly means of two adjacent sides are offset from one another by non-zero value and different from a half step or step, or one of their multiple, said step corresponding to the distance between the crest of two adjacent male assembly means on the same side of the slab, so that the assembly means of one of the sides of a slab is capable of fitting with the female assembly means only on one side of an adjacent slab without there being any offset between the edges of the two adjacent slabs.

Cet agencement particulier des moyens d'assemblage mâles sur les différents côtés de la dalle implique que la pose des dalles ne peut se faire que suivant un seul sens de pose, en effet, les moyens d'assemblage de l'un des côtés d'une dalle n'est susceptible de s'emboiter avec les moyens d'assemblage femelle que d'un seul côté d'une dalle adjacente sans qu'il y ait de décalage entre les bords des deux dalles adjacentes, de sorte qu'il n'est plus nécessaire d'apposer une marque sous les dalles indiquant le sens de pose. Par ailleurs, les dalles suivant l'invention permettent de réaliser différents calepinages pour la réalisation de sols divers et variés en utilisant des dalles présentant des motifs et/ou des décors différents par exemple.This particular arrangement of the male assembly means on the different sides of the slab implies that the laying of the slabs can be done only in one direction of installation, in fact, the assembly means of one of the sides of the slab. a slab is capable of fitting with the female assembly means only on one side of a slab adjacent without any gap between the edges of the two adjacent slabs, so it is no longer necessary to affix a mark under the slabs indicating the direction of laying. In addition, the slabs according to the invention make it possible to realize different layouts for the production of various and varied soils by using slabs having different patterns and / or decorations for example.

Lesdits moyens d'assemblage mâle (2) présentent un pas compris entre 50 et 80 mm et en ce que les moyens d'assemblage mâle (2) de deux côtés adjacents sont décalés entre eux d'une valeur comprise entre 10 et 70 mm de telle sorte que le plus petit moyen d'assemblage mâle (2) s'étendant à l'un angles de la dalle présente une largeur supérieure ou égale à 10 mm.Said male assembly means (2) have a pitch of between 50 and 80 mm and in that the male assembly means (2) of two adjacent sides are offset from one another by a value of between 10 and 70 mm. such that the smallest male assembly means (2) extending at one corner of the slab has a width greater than or equal to 10 mm.

De préférence, les moyens d'assemblage mâle de deux côté adjacents sont décalés entre eux d'une valeur d'un tiers de pas.Preferably, the male assembly means of two adjacent sides are offset from each other by a value of one third of a step.

Par ailleurs, le pas des moyens d'assemblage mâle de chaque côté de la dalle est constant et les pas des moyens d'assemblage mâle de chaque côté de la dalle sont égaux.Moreover, the pitch of the male assembly means on each side of the slab is constant and the steps of the male assembly means on each side of the slab are equal.

De plus, chaque moyen d'assemblage mâle consiste en une saillie en forme de queue d'aronde et les arrêtes de ladite queue d'aronde formant ledit moyen d'assemblage sont de préférence arrondies.In addition, each male assembly means consists of a dovetail shaped projection and the edges of said dovetail forming said connecting means are preferably rounded.

These male (2) and female (3) assembly means have a general shape of trapezium and more particularly of dovetail whose edges are rounded.

Il va de soi que les moyens d'assemblage mâle (2), et par conséquent les moyens d'assemblage femelle (3), pourront présenter une forme différente sans pour autant sortir du cadre de l'invention.It goes without saying that the male assembly means (2), and therefore the female assembly means (3), may have a different shape without departing from the scope of the invention.

Selon une caractéristiques essentielle de la dalle (1) suivant l'invention, les moyens d'assemblage mâle (2) de deux côtés opposés de la dalle (1) sont décalés entre eux d'un demi pas et les moyens d'assemblage mâle (2) de deux côté adjacents sont décalés entre eux d'une valeur non nulle et différente d'un demi pas ou d'un pas, ou un de leur multiple, de sorte que les moyens d'assemblage de l'un des côtés d'une dalle n'est susceptible de s'emboiter avec les moyens d'assemblage femelle que d'un seul côté d'une dalle adjacente sans qu'il y ait de décalage entre les bords des deux dalles adjacentes. On observera que l'on entend par « pas » la distance entre la crête de deux moyens d'assemblage mâle (2) adjacents d'un même côté de la dalle (1).According to an essential characteristic of the slab (1) according to the invention, the male assembly means (2) on two opposite sides of the slab (1) are offset from each other by half a step and the male assembly means (2) two adjacent sides are offset from each other by a non-zero value and different from a half step or a step, or one of their multiple, so that the connecting means of one of the sides a slab is capable of fitting with the female assembly means only on one side of an adjacent slab without there being any gap between the edges of the two adjacent slabs. It will be observed that "pitch" is the distance between the crest of two adjacent male assembly means (2) on the same side of the slab (1).

Cet agencement particulier des moyens d'assemblage mâle (2) sur les différents côtés de la dalle (1) implique que la pose des dalles (1), en référence à la figure 5, ne peut se faire que suivant un seul sens de pose. En effet, les moyens d'assemblage mâle (2) de l'un des côtés d'une dalle (1) n'est susceptible de s'emboiter avec les moyens d'assemblage femelle (3) que d'un seul côté d'une dalle (1) adjacente sans qu'il y ait de décalage entre les bords des deux dalles (1) adjacentes, de sorte qu'il n'est plus nécessaire d'apposer une marque sous les dalles (1) indiquant le sens de pose. On notera, à cet égard, que les parties des quatre angles de la dalle (1) présentent des formes différentes et la formation des moyens d'assemblage mâle et/ou femelle au niveau des angles des dalles (1) assemblées découlent de l'assemblage de deux panneaux consécutifs.This particular arrangement of the male assembly means (2) on the different sides of the slab (1) implies that the laying of the slabs (1), with reference to the figure 5 , can only be done following a single direction of installation. Indeed, the male assembly means (2) of one of the sides of a slab (1) is capable of fitting with the female assembly means (3) only one side d an adjacent slab (1) without there being offset between the edges of the two slabs (1) adjacent, so that it is no longer necessary to affix a mark under the slabs (1) indicating the laying direction. It will be noted in this regard that the parts of the four corners of the slab (1) have different shapes and the formation of the male and / or female assembly means at the corners of the slabs (1) assembled arise from the assembly of two consecutive panels.

Dans cet exemple particulier de réalisation, les moyens d'assemblage mâle (2) de deux côté adjacents sont décalés entre eux d'une valeur d'un tiers de pas. Par ailleurs, le pas des moyens d'assemblage mâle (2) de chaque côté de la dalle (1) est constant et les pas des moyens d'assemblage mâle (2) de chaque côté de la dalle (1) sont égaux. De préférence, la valeur dudit pas est compris entre 1/6 et 1/10 de la longueur d'un côté de la dalle (1) et, de préférence entre 1/8 et 1/9 de la longueur d'un côté de la dalle (1).In this particular embodiment, the male assembly means (2) of two adjacent sides are offset from each other by a value of one third of a step. Furthermore, the pitch of the male assembly means (2) on each side of the slab (1) is constant and the steps of the male assembly means (2) on each side of the slab (1) are equal. Preferably, the value of said pitch is between 1/6 and 1/10 of the length of one side of the slab (1) and preferably between 1/8 and 1/9 of the length of one side of the slab. the slab (1).

De préférence, on choisira des moyens d'assemblage mâle (2) présentant un pas compris entre 50 et 80 mm et un décalage entre les moyens d'assemblage mâle (2) de deux côtés adjacents d'une valeur comprise entre 10 et 70 mm de telle sorte que le plus petit moyen d'assemblage mâle (2) s'étendant à l'un angles de la dalle présente une largeur supérieure ou égale à 10 mm. Ainsi, les moyens d'assemblage mâle (2) situés à l'un des angles de la dalle (1) présente une rigidité suffisante évitant toute détérioration lors de la pose des dalles (1).Preferably, male assembly means (2) having a pitch of between 50 and 80 mm and an offset between the male assembly means (2) of two adjacent sides of a value of between 10 and 70 mm will be chosen. such that the smallest male assembly means (2) extending at one corner of the slab has a width greater than or equal to 10 mm. Thus, the male assembly means (2) located at one of the corners of the slab (1) has a sufficient rigidity avoiding damage during laying slabs (1).

Préférentiellement, le pas est de 60 mm et le plus petit moyen d'assemblage mâle (2) s'étendant à l'un angles de la dalle présente une largeur de 13 mm.Preferably, the pitch is 60 mm and the smallest male assembly means (2) extending at one corner of the slab has a width of 13 mm.

On notera que les dalles suivant l'invention permettent avantageusement la réalisation de différents calepinages. Ainsi, il est possible de réaliser un grand nombre de de sols divers et variés en utilisant des dalles présentant des motifs et/ou des décors différents par exemple.It will be noted that the slabs according to the invention advantageously make it possible to produce different layouts. Thus, it is possible to achieve a large number of diverse and varied soils using slabs with different patterns and / or decorations for example.

Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des illustrations particulières et en aucun cas limitatif quant au domaine d'application de l'invention.Finally, it is obvious that the examples which have just been given are only particular illustrations and in no way limiting as to the field of application of the invention.
