Description

PANNEAU POUR LA REALISATION D’UN REVÊTEMENT DE SOL EN PANEL FOR THE PRODUCTION OF A FLOOR COVERING
POSE LIBRE FREE POST
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention se rapporte au domaine des revêtements de sol en pose libre, et concerne plus particulièrement un panneau, de préférence en polychlorure de vinyle, ayant une forme de lame ou de dalle pour la réalisation d’un tel revêtement, dont l’assemblage s’effectue selon une cinématique inclinée sur un premier bord, et verticale sur un second bord adjacent. The present invention relates to the field of free-standing floor coverings, and relates more particularly to a panel, preferably made of polyvinyl chloride, having a blade or slab shape for producing such a covering, the assembly of which takes place according to a kinematics inclined on a first edge, and vertical on a second adjacent edge.
ART ANTERIEUR PRIOR ART
D’une manière générale, ce type panneau comprend deux paires de côtés opposés définissant : Generally, this type of panel includes two pairs of opposite sides defining:
- deux bords opposés à assemblage incliné, dont un bord comprend des moyens d’accouplement mâles ménagés à partir d’une paroi latérale du panneau, et un bord opposé comprenant des moyens d’accouplement femelles complémentaires ménagés à partir d’une paroi latérale du panneau ; - two opposite edges with inclined assembly, one edge of which comprises male coupling means arranged from a side wall of the panel, and an opposite edge comprising complementary female coupling means formed from a side wall of the sign ;
- deux bords opposés à assemblage vertical, dont un bord comprend des moyens d’accouplement mâles ménagés à partir d’une face inférieure du panneau, et un bord opposé comprenant des moyens d’accouplement femelles complémentaires ménagés à partir d’une face supérieure du panneau. - two opposite edges with vertical assembly, one edge of which comprises male coupling means arranged from a lower face of the panel, and an opposite edge comprising complementary female coupling means formed from an upper face of the sign.
Ce type de panneau est illustré par exemple par le document EP 3 105 392, et le document US 2013/0309441. Ces documents décrivent tous deux un panneau ayant des premier et second moyens d’accouplement mâles/femelles complémentaires sur des paires opposées de côtés pour assembler des panneaux similaires afin de former un revêtement de sol. Les moyens d’accouplement des petits côtés présentent des moyens complémentaires pour s’opposer au désassemblage vertical, et des parois externes inclinées par rapport à un plan vertical et orientées vers l’intérieur du panneau. L’assemblage est réalisé en inclinant les panneaux le long d'un grand côté et en les verrouillant verticalement sur un petit côté. Les moyens décrits dans le document EP 3 105 392, pour s’opposer au désassemblage vertical de deux panneaux, notamment sous la forme de renflements et cavités, ne présentent pas une efficacité optimale. This type of panel is illustrated for example by document EP 3 105 392, and document US 2013/0309441. These documents both describe a panel having first and second complementary male / female coupling means on opposite pairs of sides to assemble similar panels to form a floor covering. The coupling means of the short sides have complementary means to oppose the vertical disassembly, and external walls inclined with respect to a vertical plane and oriented towards the inside of the panel. The assembly is carried out by tilting the panels along a long side and locking them vertically on a small side. The means described in document EP 3 105 392, for opposing the vertical disassembly of two panels, in particular in the form of bulges and cavities, do not have optimal effectiveness.
Par ailleurs, le document US 2013/0309441 décrit une languette femelle présentant une partie chanfreinée au niveau de la face inférieure du panneau, en vue de faciliter l’assemblage de deux panneaux, mais qui ne présente pas une efficacité optimale. Furthermore, document US 2013/0309441 describes a female tongue having a chamfered part at the level of the underside of the panel, with a view to facilitating the assembly of two panels, but which does not have optimal efficiency.
Lors de l’opération de pose de ce type de revêtement de sol, le poseur assemble en premier lieu le grand côté selon une direction d’assemblage inclinée, par exemple selon un angle comprise entre 10° et 50° et, tout en conservant l’angle d’inclinaison du panneau, il fait ensuite glisser celui-ci latéralement vers le panneau précédent jusqu’à venir en butée. During the laying operation of this type of floor covering, the installer first assembles the long side in an inclined direction of assembly, for example at an angle between 10 ° and 50 ° and, while keeping the angle of inclination of the panel, it then slides it laterally towards the previous panel until it comes to a stop.
Avec le panneau du document EP 3 105 392, et en référence à la figure 1 qui l’illustre, la partie mâle (Al) du panneau à poser vient en appui contre la partie femelle (A2) du panneau déjà posé au niveau de la partie supérieure du panneau. Dans la pratique c’est la paroi latérale externe de la partie mâle, notamment située sous la cavité (A3), qui vient buter contre l’arrête interne supérieure de la partie femelle. Ensuite, à mesure que le panneau pivote vers le bas, celui-ci suit la trajectoire inclinée (R) pour venir s’assembler. Ainsi le panneau « recule » en s’assemblant ce qui oblige à l’avoir positionné légèrement plus en avant que sa position de verrouillage, ce qui complexifie l’opération de pose des panneaux. Cet inconvénient se retrouve également dans le panneau décrit dans le document US 2013/0309441. With the panel of document EP 3 105 392, and with reference to FIG. 1 which illustrates it, the male part (Al) of the panel to be laid comes to bear against the female part (A2) of the panel already placed at the level of the upper part of the panel. In practice, it is the external lateral wall of the male part, in particular situated under the cavity (A3), which abuts against the upper internal edge of the female part. Then, as the panel pivots down, it follows the inclined path (R) to come together. Thus the panel "moves back" by assembling which requires having it positioned slightly more forward than its locked position, which complicates the operation of installing the panels. This drawback is also found in the panel described in document US 2013/0309441.
EXPOSE DE L’INVENTION STATEMENT OF THE INVENTION
L’un des buts de l’invention est donc de remédier aux inconvénients précités en proposant un panneau pour la réalisation d’un revêtement de sol en pose libre, dont l’assemblage s’effectue selon une cinématique inclinée sur un bord, puis verticale sur un bord adjacent. Un autre objectif de l’invention est de faciliter l’assemblage de deux panneaux similaires, et de fournir également un panneau présentant une résistance au désassemblage horizontal et vertical optimale, ainsi qu’une esthétique satisfaisante.

- les moyens d’accouplement femelles des bords à assemblage vertical comprennent une rainure femelle s’étendant le long du bord et débouchant sur la face supérieure du panneau, de manière à définir un tenon femelle ; - The female coupling means of the vertically assembled edges include a female groove extending along the edge and opening onto the upper face of the panel, so as to define a female tenon;
- les moyens d’accouplement mâles des bords à assemblage vertical comprennent un ergot ou une encoche et les moyens d’accouplement femelles des bords à assemblage vertical comprennent une encoche ou un ergot complémentaire formant, après assemblage de deux panneaux adjacents, des butées d’arrêt à l’encontre d’un déplacement vertical entre deux panneaux adjacents assemblés. - The male coupling means of the vertically assembled edges comprise a lug or a notch and the female coupling means of the vertically assembled edges include a notch or a complementary lug forming, after assembly of two adjacent panels, stops of stop against vertical displacement between two adjacent panels assembled.
Ainsi, le panneau selon l’invention présente une cinématique d’assemblage inclinée sur un côté, puis par un mouvement de pivotement du panneau, verticale sur un côté adjacent. Par ailleurs, le fait que le tenon mâle présente une paroi externe inclinée par rapport à un plan vertical et vers l’extérieur du panneau favorise l’assemblage vertical pendant le mouvement de rotation. Le poseur vient positionner les panneaux en butée : la partie inférieure du tenon mâle vient s’appuyer contre la partie supérieure de la rainure femelle. En conséquence, lors de la pose, le poseur voit la rainure et peut donc facilement positionner la paroi externe du tenon mâle au droit de la rainure pour commencer l’assemblage. Ensuite, d’une manière avantageuse, lors du pivotement, les deux panneaux se rapprochent l’un de l’autre. Les contraintes d’usinage pour avoir un contact parfait en surface des panneaux sont alors plus faciles à respecter. Thus, the panel according to the invention has an assembly kinematics inclined on one side, then by a pivoting movement of the panel, vertical on an adjacent side. Furthermore, the fact that the male stud has an external wall inclined with respect to a vertical plane and towards the outside of the panel promotes vertical assembly during the rotational movement. The installer places the panels in abutment: the lower part of the male stud comes to rest against the upper part of the female groove. Consequently, during installation, the installer sees the groove and can therefore easily position the external wall of the male stud in line with the groove to start assembly. Then, advantageously, during the pivoting, the two panels approach each other. The machining constraints to have perfect contact on the surface of the panels are then easier to respect.
La présence des ergot et encoche permet également d’optimiser la résistance au désassemblage vertical, car les angles saillants des ergot et encoche permettent un verrouillage plus efficace que les renflements et cavités de l’art antérieur. The presence of the lug and notch also makes it possible to optimize the resistance to vertical disassembly, since the projecting angles of the lug and notch allow a more effective locking than the bulges and cavities of the prior art.
De préférence, le tenon externe femelle comporte une partie chanfreinée au niveau de la face inférieure du panneau et formant un angle compris entre 2° et 20° par rapport à la face inférieure du panneau. La partie chanfreinée autorise l’abaissement du tenon femelle lors de l’assemblage de deux panneaux adjacents pour venir, par déformation, en contact avec le sol et procurer ainsi une réduction de l’effort d’assemblage. Preferably, the female external stud has a chamfered part at the lower face of the panel and forming an angle between 2 ° and 20 ° relative to the lower face of the panel. The chamfered part allows the lowering of the female post during the assembly of two adjacent panels to come, by deformation, into contact with the ground and thus provide a reduction in the assembly effort.
D’une manière avantageuse, la partie chanfreinée du tenon femelle s’étend jusqu’au droit de l’arête supérieure interne du tenon femelle, c’est-à-dire notamment jusqu’au droit du point le plus élevé du tenon femelle à partir du sol. Cette caractéristique permet une meilleure flexion du tenon femelle pendant l’assemblage. Advantageously, the chamfered part of the female post extends to the right of the internal upper edge of the female post, that is to say in particular to the right of the highest point of the female post at from the ground. This characteristic allows better bending of the female post during assembly.
Selon une forme de réalisation particulière, et pour faciliter la fabrication par usinage, le tenon mâle présente une paroi interne inclinée par rapport à un plan vertical et vers l’extérieur du panneau. Par exemple, les parois externe et interne du tenon mâle sont inclinées selon un angle compris entre 1 et 45°, et de préférence compris entre 5° et 15°, et par exemple selon un même angle. Pour faciliter également la flexion du tenon mâle lors de l’assemblage, celui-ci comporte une partie chanfreinée au niveau de la face supérieure du panneau et formant un angle compris entre 2° et 20° par rapport à la face supérieure du panneau. According to a particular embodiment, and to facilitate manufacturing by machining, the male stud has an internal wall inclined relative to a vertical plane and towards the outside of the panel. For example, the external and internal walls of the male stud are inclined at an angle between 1 and 45 °, and preferably between 5 ° and 15 °, and for example at the same angle. To also facilitate the bending of the male stud during assembly, it has a chamfered part at the upper face of the panel and forming an angle between 2 ° and 20 ° relative to the upper face of the panel.
Afin d’améliorer davantage la résistance au désassemblage vertical, les moyens d’accouplement mâles des bords à assemblage vertical comprennent deux ergots ou encoches, et les moyens d’accouplement femelles des bords à assemblage vertical comprennent deux encoches ou ergots complémentaires. In order to further improve the resistance to vertical disassembly, the male coupling means of the vertically assembled edges comprise two lugs or notches, and the female coupling means of the vertically assembled edges comprise two complementary notches or lugs.
Selon un exemple particulier de réalisation, l’ergot ou encoche est ménagé(e) sur la paroi externe du tenon mâle et, de manière complémentaire, l’encoche ou ergot est ménagé(e) sur une paroi interne de la rainure femelle. According to a particular embodiment, the lug or notch is formed on the external wall of the male stud and, in a complementary manner, the notch or lug is formed on an internal wall of the female groove.
Selon un autre exemple, pris seul, ou en combinaison avec l’exemple précédent, l’ergot ou encoche est ménagé(e) sur la paroi externe du tenon femelle et, de manière complémentaire, l’encoche ou ergot est ménagé(e) sur une paroi interne de la rainure mâle. According to another example, taken alone, or in combination with the previous example, the lug or notch is formed on the external wall of the female post and, in a complementary manner, the notch or lug is formed on an internal wall of the male groove.
Selon une forme de réalisation particulière, les moyens d’accouplement mâles des bords à assemblage incliné comprennent une languette faisant saillie de la paroi latérale, notamment orthogonalement, du panneau et sur toute la longueur du bord, et les moyens d’accouplement femelles des bords à assemblage incliné comprennent une rainure complémentaire ménagée dans la paroi latérale du panneau et sur toute la longueur du bord. According to a particular embodiment, the male coupling means of the edges with inclined assembly comprise a tongue projecting from the side wall, in particular orthogonally, from the panel and over the entire length of the edge, and the female coupling means from the edges inclined assembly include a complementary groove formed in the side wall of the panel and along the entire length of the edge.
De préférence, la languette comprend un ergot faisant saillie verticalement, et la rainure complémentaire comprend une encoche complémentaire formant, après assemblage de deux panneaux adjacents, des butées d’arrêt à l’encontre d’un déplacement horizontal entre deux panneaux adjacents assemblés. Preferably, the tongue comprises a lug protruding vertically, and the complementary groove comprises a complementary notch forming, after assembly of two adjacent panels, stop stops against a horizontal movement between two adjacent panels assembled.
Avantageusement, la rainure complémentaire des moyens d’accouplement femelles des bords à assemblage incliné définit une languette femelle inférieure flexible destinée à s’écarter lors de l’engagement incliné de la languette des moyens d’accouplement mâles, puis à reprendre sa position après engagement pour augmenter la résistance au désassemblage vertical et horizontal de deux panneaux adjacents assemblés. Advantageously, the complementary groove of the female coupling means of the edges with inclined assembly defines a flexible lower female tongue intended to move apart during the inclined engagement of the tongue of the male coupling means, then return to its position after engagement to increase the resistance to vertical and horizontal disassembly of two adjacent panels assembled.

DESCRIPTION DETATELEE DE L’INVENTION DETAILED DESCRIPTION OF THE INVENTION
En référence à la figure 2, l’invention concerne un panneau (1) ayant une forme de lame ou de dalle pour la réalisation d’un revêtement de sol en pose libre. Referring to Figure 2, the invention relates to a panel (1) having a blade or slab shape for the production of a free-standing floor covering.
Le panneau (1) de sol selon l’invention est réalisé, de préférence, dans une matière plastique, tel que du polychlorure de vinyle, par exemple plastifié, et comportant éventuellement une charge minérale. Toutefois, il est bien évident que le panneau (1) selon l’invention peut être obtenu dans toute matière plastique appropriée. Selon une forme de réalisation particulière, le panneau (1) est résilient, par exemple réalisé à partir de polychlorure de vinyle plastifié ou rigide. The floor panel (1) according to the invention is preferably made of a plastic material, such as polyvinyl chloride, for example plasticized, and optionally comprising a mineral filler. However, it is obvious that the panel (1) according to the invention can be obtained in any suitable plastic material. According to a particular embodiment, the panel (1) is resilient, for example made from plasticized or rigid polyvinyl chloride.
De préférence, le panneau (1) présente un noyau lié à une couche décorative constituée d’un film décor lié à une couche de surface transparente. Preferably, the panel (1) has a core linked to a decorative layer consisting of a decorative film linked to a transparent surface layer.
Le noyau peut être monocouche ou multicouche, et réalisé par exemple à partir de matière plastique telle que du polychlorure de vinyle, du polypropylène, du polyuréthane, du polyuréthane thermoplastique, du polyéthylène, du polyéthylène téréphtalate, ou tout autre matière plastique appropriée, et comprenant éventuellement des charges sous forme de fibres, copeaux, poussières ou sciure de bois et/ou des charges minérales, par exemple craie, chaux, talc, et un ou plusieurs plastifiants afin de définir la rigidité du noyau. The core can be monolayer or multilayer, and produced for example from plastic material such as polyvinyl chloride, polypropylene, polyurethane, thermoplastic polyurethane, polyethylene, polyethylene terephthalate, or any other suitable plastic material, and comprising optionally fillers in the form of fibers, shavings, dust or sawdust and / or mineral fillers, for example chalk, lime, talc, and one or more plasticizers in order to define the stiffness of the core.
Le noyau, ou une couche du noyau dans le cas d’un noyau multicouche, peut éventuellement être à base d’urée formol ou de mélamine formol et de bois, par exemple des couches de fibres de densité moyenne (MDF) ou de fibres de densité Haute (HDF). Chaque couche peut également être une couche de bois stratifié, de bois composite (WPC « wood plastic composite » en langue anglaise). The core, or a core layer in the case of a multilayer core, may optionally be based on urea formaldehyde or melamine formaldehyde and wood, for example layers of medium density fibers (MDF) or High density (HDF). Each layer can also be a layer of laminated wood, of composite wood (WPC "wood plastic composite" in English).
Chaque couche peut être compacte ou moussée. A titre d’exemple, le noyau peut être réalisé avec une couche moussée en polychlorure de vinyle rigide intercalée entre deux couches de polychlorure de vinyle rigide compactes. Each layer can be compact or foamed. For example, the core can be made with a rigid polyvinyl chloride foam layer interposed between two layers of compact rigid polyvinyl chloride.
D’une manière connue, le panneau (1) comprend une forme rectangulaire et comprend deux paires de côtés opposés définissant quatre bords, dont deux bords opposés à assemblage incliné (2), et deux autres bords opposés à assemblage vertical (3). Bien entendu, le panneau (1) peut présenter tout aussi bien une forme carrée. In a known manner, the panel (1) comprises a rectangular shape and comprises two pairs of opposite sides defining four edges, including two opposite edges with inclined assembly (2), and two other opposite edges with vertical assembly (3). Of course, the panel (1) can also have a square shape.
De ce qui précède, l’assemblage de ce type de panneau (1) se fait selon une cinématique inclinée sur un premier bord (2), par exemple selon un angle comprise entre 10° et 50°, et selon une cinématique verticale sur un second bord (3) adjacent. En particulier, lors de la pose de ce type de panneau (1), le poseur pose une première ligne de panneaux (1), en les assemblant côte à côte selon une cinématique d’assemblage verticale. Ensuite, le poseur débute une seconde ligne de panneaux (1) par l’assemblage d’un premier panneau (1), selon une cinématique inclinée par rapport aux panneaux (1) de la ligne précédente. Les panneaux (1) suivants de la seconde ligne sont assemblés selon une cinématique inclinée par rapport aux panneaux (1) de la ligne précédente et, par un mouvement de pivotement du panneau (1) en direction du sol, le panneau (1) est assemblé au panneau (1) adjacent selon une cinématique verticale. From the above, the assembly of this type of panel (1) is done according to a kinematics inclined on a first edge (2), for example at an angle between 10 ° and 50 °, and according to a vertical kinematics on a second edge (3) adjacent. In particular, during the installation of this type of panel (1), the installer places a first line of panels (1), by assembling them side by side according to a kinematics of vertical assembly. Then, the installer starts a second line of panels (1) by assembling a first panel (1), according to a kinematics inclined relative to the panels (1) of the previous line. The following panels (1) of the second line are assembled according to a kinematics inclined with respect to the panels (1) of the previous line and, by a pivoting movement of the panel (1) towards the ground, the panel (1) is assembled to the adjacent panel (1) according to vertical kinematics.
D’une manière préférée, lorsque les panneaux (1) sont de formes rectangulaires, les grands côtés s’assemblent selon une cinématique inclinée, tandis que les petits côtés s’assemblent selon une cinématique verticale. Preferably, when the panels (1) are rectangular, the long sides are assembled according to an inclined kinematics, while the short sides are assembled according to a vertical kinematics.
En référence à la figure 3, les bords opposés à assemblage incliné (2) consistent en un bord comprenant des moyens d’accouplement mâles (4) ménagés à partir d’une paroi latérale du panneau (1), et en un bord opposé comprenant des moyens d’accouplement femelles (5) complémentaires ménagés à partir d’une paroi latérale du panneau (1). Referring to Figure 3, the opposite edges inclined assembly (2) consist of an edge comprising male coupling means (4) formed from a side wall of the panel (1), and an opposite edge comprising complementary female coupling means (5) formed from a side wall of the panel (1).
En référence à la figure 4, les bords opposés à assemblage vertical (3), consistent en un bord comprenant des moyens d’accouplement mâles (6) ménagés à partir d’une face inférieure du panneau (1), et en un bord opposé comprenant des moyens d’accouplement femelles (7) complémentaires ménagés à partir d’une face supérieure du panneau (1). With reference to FIG. 4, the opposite edges with vertical assembly (3) consist of an edge comprising male coupling means (6) formed from a lower face of the panel (1), and an opposite edge comprising complementary female coupling means (7) formed from an upper face of the panel (1).
En référence à la figure 5, après assemblage, les arêtes supérieures et en regard de deux panneaux (1) sont de préférence en contact pour une esthétique optimale. Referring to Figure 5, after assembly, the upper edges and facing two panels (1) are preferably in contact for optimal aesthetics.
Selon l’invention et en référence à la figure 3, les moyens d’accouplement mâles (4) des bords à assemblage incliné (2) comprennent une languette (8) faisant saillie de la paroi latérale du panneau (1) et sur toute la longueur du bord. Les moyens d’accouplement femelles (5) des bords à assemblage incliné (2) comprennent une rainure (9) complémentaire ménagée dans la paroi latérale du panneau (1) et sur toute la longueur du bord. La coopération entre la languette (8) et la rainure (9) permet de résister d’une manière optimale au désassemblage vertical de deux panneaux (1). According to the invention and with reference to FIG. 3, the male coupling means (4) of the edges with inclined assembly (2) comprise a tongue (8) projecting from the side wall of the panel (1) and over the entire edge length. The female coupling means (5) of the edges with inclined assembly (2) comprise a complementary groove (9) formed in the side wall of the panel (1) and over the entire length of the edge. The cooperation between the tongue (8) and the groove (9) makes it possible to optimally resist the vertical disassembly of two panels (1).
Pour résister au désassemblage horizontal, la languette (8) comprend un ergot (8a) faisant saillie verticalement, et la rainure (9) complémentaire comprend une encoche (9a) complémentaire formant, après assemblage de deux panneaux (1) adjacents, des butées d’arrêt à l’encontre d’un déplacement horizontal entre deux panneaux (1) adjacents assemblés. Bien entendu, la languette (8) peut comprendre une encoche et la rainure (9) peut comprendre un ergot, sans sortir du cadre de l’invention. To resist horizontal disassembly, the tongue (8) comprises a lug (8a) projecting vertically, and the complementary groove (9) comprises a complementary notch (9a) forming, after assembly of two adjacent panels (1), 'stop against a horizontal movement between two adjacent panels (1) assembled. Of course, the tongue (8) may include a notch and the groove (9) may include a lug, without departing from the scope of the invention.
Comme précédemment évoqué, l’engagement de la languette (8) dans la rainure (9) s’effectue selon une cinématique inclinée, puis par pivotement du panneau (1), la languette (8) est déplacée horizontalement vers le fond de la rainure. As previously mentioned, the engagement of the tongue (8) in the groove (9) takes place according to an inclined kinematics, then by pivoting of the panel (1), the tongue (8) is moved horizontally towards the bottom of the groove .
Selon une autre forme de réalisation des bords opposés à assemblage incliné (2) illustrée à la figure 6, la rainure (9) complémentaire des moyens d’accouplement femelles (5) définit une languette femelle inférieure (9b) flexible et destinée à s’écarter lors de l’engagement incliné de la languette (8) des moyens d’accouplement mâles (4), puis à reprendre sa position après engagement pour augmenter la résistance au désassemblage vertical et horizontal de deux panneaux (1) adjacents assemblés. According to another embodiment of the edges opposite to an inclined assembly (2) illustrated in FIG. 6, the groove (9) complementary to the female coupling means (5) defines a flexible lower female tongue (9b) intended for s' move aside during the inclined engagement of the tongue (8) male coupling means (4), then return to its position after engagement to increase the resistance to vertical and horizontal disassembly of two adjacent panels (1) assembled.
En référence aux figures 4 et 5, les moyens d’accouplement mâles (6) des bords à assemblage vertical (3) comprennent une rainure mâle (6a) s’étendant le long du bord et débouchant sur la face inférieure du panneau (1), de manière à définir un tenon mâle (6b). Referring to Figures 4 and 5, the male coupling means (6) of the vertically assembled edges (3) comprise a male groove (6a) extending along the edge and opening onto the underside of the panel (1) , so as to define a male stud (6b).
De la même manière, les moyens d’accouplement femelles (7) des bords à assemblage vertical (3) comprennent une rainure femelle (7a) s’étendant le long du bord et débouchant sur la face supérieure du panneau (1), de manière à définir un tenon femelle (7b). Similarly, the female coupling means (7) of the vertically assembled edges (3) comprise a female groove (7a) extending along the edge and opening onto the upper face of the panel (1), so to define a female post (7b).
Les tenons mâle et femelle (6b, 7b) comprennent des sections transversales sensiblement rectangulaires, et sont souples et déformables élastiquement pour permettre leur engagement dans les rainures femelle et mâle (6a, 7a) correspondantes. Le tenon mâle (6b) présente une paroi externe (6c) inclinée par rapport à un plan vertical et vers l’extérieur du panneau (1), selon un angle compris entre 1 et 45°, et de préférence compris entre 5 et 15°. Une inclinaison de la paroi externe (6c) comprise entre 5 et 15° permet d’obtenir un bon compromis entre la facilité d’assemblage des panneaux et la résistance au désassemblage horizontal des moyens d’accouplement. Ainsi, lors de l’engagement du tenon mâle (6b) dans la rainure femelle (7a), selon une cinématique verticale, le tenon mâle (6b) vient s’appuyer contre la partie supérieure du tenon femelle (7b). En conséquence, pendant l’opération de pose, le poseur voit la rainure femelle (7a) et peut donc facilement positionner la paroi externe (6c) du tenon mâle (6b) au droit de la rainure femelle (7a) pour commencer l’assemblage. Ceci facilite très nettement l’opération d’assemblage vertical pendant le mouvement de rotation. Par ailleurs, et d’une manière avantageuse, étant donné l’inclinaison vers l’extérieur de la paroi externe (6c) du tenon mâle (6b) et l’inclinaison complémentaire de la paroi interne de la rainure femelle (7a), lors du pivotement, les deux panneaux (1) se rapprochent l’un de l’autre. Ceci facilite davantage l’opération de pose, et les contraintes d’usinage pour avoir un contact parfait en surface des panneaux (1) sont aussi plus faciles à respecter. The male and female tenons (6b, 7b) comprise substantially rectangular cross sections, and are flexible and elastically deformable to allow their engagement in the corresponding female and male grooves (6a, 7a). The male stud (6b) has an outer wall (6c) inclined relative to a vertical plane and towards the outside of the panel (1), at an angle between 1 and 45 °, and preferably between 5 and 15 ° . An inclination of the external wall (6c) of between 5 and 15 ° makes it possible to obtain a good compromise between the ease of assembly of the panels and the resistance to horizontal disassembly of the coupling means. Thus, during the engagement of the male stud (6b) in the female groove (7a), according to a vertical kinematics, the male stud (6b) comes to bear against the upper part of the female stud (7b). Consequently, during the laying operation, the installer sees the female groove (7a) and can therefore easily position the external wall (6c) of the male stud (6b) in line with the female groove (7a) to start assembly. . This very clearly facilitates the vertical assembly operation during the rotational movement. Furthermore, and advantageously, given the inclination towards the outside of the external wall (6c) of the male stud (6b) and the complementary inclination of the internal wall of the female groove (7a), during pivoting, the two panels (1) approach each other. This further facilitates the laying operation, and the machining constraints to have perfect contact with the surface of the panels (1) are also easier to comply with.
Selon une forme de réalisation particulière, le tenon mâle (6b) présente une paroi interne inclinée par rapport à un plan vertical et vers l’extérieur ou l’intérieur du panneau (1)· According to a particular embodiment, the male stud (6b) has an internal wall inclined relative to a vertical plane and towards the outside or inside of the panel (1) ·
De préférence, et pour faciliter l’assemblage de deux panneaux (1) adjacents, le tenon mâle (6b) présente une paroi interne inclinée vers l’extérieur du panneau (1), selon un angle compris entre 1 et 45°, et de préférence compris entre 5 et 15°. Une inclinaison de la paroi interne du tenon mâle (6b) comprise entre 5 et 15° permet également d’obtenir un bon compromis entre la facilité d’assemblage des panneaux et la résistance au désassemblage horizontal des moyens d’accouplement. De façon plus préférentielle, le tenon mâle (6b) présente une paroi interne inclinée selon le même angle que la paroi externe (6c). Cette caractéristique permet également de faciliter la fabrication, et en particulier l’usinage des moyens d’accouplement mâles (6) et femelles (7) complémentaires . L’engagement du tenon mâle (6b) dans la rainure femelle (7a) permet de résister au désassemblage horizontal de deux panneaux (1) assemblés. Preferably, and to facilitate the assembly of two adjacent panels (1), the male stud (6b) has an internal wall inclined towards the outside of the panel (1), at an angle between 1 and 45 °, and of preferably between 5 and 15 °. An inclination of the internal wall of the male stud (6b) of between 5 and 15 ° also makes it possible to obtain a good compromise between the ease of assembly of the panels and the resistance to horizontal disassembly of the coupling means. More preferably, the male stud (6b) has an internal wall inclined at the same angle as the external wall (6c). This characteristic also makes it possible to facilitate the manufacture, and in particular the machining of the complementary male (6) and female (7) coupling means. The engagement of the male stud (6b) in the female groove (7a) makes it possible to resist the horizontal disassembly of two assembled panels (1).
Afin de participer à la résistance au désassemblage vertical, les moyens d’accouplement mâles (6) des bords à assemblage vertical (3) comprennent un ergot (10) ou une encoche (11), et les moyens d’accouplement femelles (7) des bords à assemblage vertical (3) comprennent une encoche (11) ou un ergot (10) complémentaire formant, après assemblage de deux panneaux (1) adjacents, des butées d’arrêt à l’encontre d’un déplacement vertical entre deux panneaux (1) adjacents assemblés. In order to participate in the resistance to vertical disassembly, the male coupling means (6) of the vertically assembled edges (3) comprise a lug (10) or a notch (11), and the female coupling means (7) vertically assembled edges (3) include a notch (11) or a complementary lug (10) forming, after assembly of two adjacent panels (1), stops against a vertical movement between two panels (1) adjacent assembled.
De ce qui précède, plusieurs formes de réalisation sont envisageables. Par exemple, l’ergot (10) ou encoche (11) est ménagé(e) sur la paroi externe du tenon mâle (6b) et, de manière complémentaire, l’encoche (11) ou ergot (10) est ménagé(e) sur une paroi interne de la rainure femelle (7a). From the above, several embodiments are possible. For example, the lug (10) or notch (11) is formed on the external wall of the male stud (6b) and, in a complementary manner, the notch (11) or lug (10) is formed ) on an internal wall of the female groove (7a).
Selon une autre forme de réalisation, l’ergot (10) ou encoche (11) est ménagé(e) sur la paroi externe du tenon femelle (7b) et, de manière complémentaire, l’encoche (11) ou ergot (10) est ménagé(e) sur une paroi interne de la rainure mâle (6a). According to another embodiment, the lug (10) or notch (11) is formed (e) on the external wall of the female stud (7b) and, in a complementary manner, the notch (11) or lug (10) is formed on an internal wall of the male groove (6a).
De préférence, ces deux formes de réalisation sont combinées de sorte que les moyens d’accouplement mâles (6) des bords à assemblage vertical (3) comprennent deux ergots (10) ou encoches (11), et les moyens d’accouplement femelles (7) des bords à assemblage vertical (3) comprennent deux encoches (11) ou ergots (10) complémentaires. Preferably, these two embodiments are combined so that the male coupling means (6) of the vertically assembled edges (3) comprise two lugs (10) or notches (11), and the female coupling means ( 7) vertically assembled edges (3) include two complementary notches (11) or lugs (10).
Afin d’améliorer davantage la résistance au désassemblage vertical les rainures mâle (6a) et femelle (7a) présentent chacune une paroi externe, c’est-à-dire positionnée, non pas du côté du corps du panneau (1), mais du côté de l’extérieur du panneau (1), destinée à être en contact, après assemblage des deux panneaux (1). Pour obtenir le contact les rainures (6a, 7a) et tenons (6b, 7b) présentent des largeurs et/ou inclinaisons appropriées. A titre d’exemple, les tenons (6b, 7b) et rainures (6a, 7a) présentent des largeurs de l’ordre de 2 mm, et sont inclinés de 10° par rapport à la verticale et vers l’extérieur du panneau (1). Ainsi, la paroi externe de la rainure mâle (6a) est en contact avec la paroi externe de la rainure femelle (7a). En pratique, après assemblage ces parois en contact sont parallèles entre elles. Après assemblage, et de façon préférentielle, le tenon mâle (6b) est en contact avec le fond de la rainure femelle (7a) afin d’avoir un appui vertical. Par ailleurs, après assemblage, il subsiste de préférence un jeu de quelques dixièmes de millimètres entre la paroi verticale externe du tenon femelle (7b), située sous l’encoche (11), avec la paroi verticale en regard de la rainure mâle (6a), située sous l’ergot (10). Cette caractéristique permet de faciliter l’assemblage. In order to further improve the resistance to vertical disassembly, the male (6a) and female (7a) grooves each have an external wall, that is to say positioned, not on the side of the body of the panel (1), but of the side of the outside of the panel (1), intended to be in contact, after assembly of the two panels (1). To obtain contact, the grooves (6a, 7a) and tenons (6b, 7b) have suitable widths and / or inclinations. For example, the studs (6b, 7b) and grooves (6a, 7a) have widths of the order of 2 mm, and are inclined by 10 ° relative to the vertical and towards the outside of the panel ( 1). Thus, the external wall of the male groove (6a) is in contact with the external wall of the female groove (7a). In practice, after assembly, these walls in contact are mutually parallel. After assembly, and preferably, the male stud (6b) is in contact with the bottom of the female groove (7a) in order to have a vertical support. Furthermore, after assembly, there is preferably a clearance of a few tenths of a millimeter between the external vertical wall of the female stud (7b), located under the notch (11), with the vertical wall facing the male groove (6a ), located under the lug (10). This feature makes assembly easier.
Selon une autre caractéristique de l’invention, le tenon femelle (7b) comporte une partie chanfreinée (12) au niveau de la face inférieure du panneau (1) et formant un angle compris entre 2° et 20° par rapport à la face inférieure du panneau (1). Ainsi, lors de l’assemblage des deux panneaux (1) adjacents, la partie chanfreinée (12) autorise l’abaissement du tenon femelle (7b) pour venir, par déformation, en contact avec le sol, et procurer ainsi une réduction de l’effort d’assemblage. Pour faciliter davantage l’opération d’assemblage, la partie chanfreinée (12) du tenon femelle (7b) s’étend jusqu’au droit de l’arête supérieure interne du tenon femelle (7b). According to another characteristic of the invention, the female tenon (7b) has a chamfered part (12) at the level of the lower face of the panel (1) and forming an angle between 2 ° and 20 ° relative to the lower face of the panel (1). Thus, during the assembly of the two adjacent panels (1), the chamfered part (12) allows the lowering of the female stud (7b) to come, by deformation, into contact with the ground, and thus provide a reduction of the 'assembly effort. To further facilitate the assembly operation, the chamfered part (12) of the female post (7b) extends to the right of the internal upper edge of the female post (7b).
Par ailleurs, la face supérieure du panneau (1) peut également présenter des chanfreins (13) au niveau du tenon mâle (6b) et de la rainure femelle (7a) afin de participer à l’esthétique générale des panneaux (1), après assemblage. Chaque chanfrein (13) forme un angle compris entre 2° et 20° par rapport à la face supérieure du panneau (1). L’interface entre les deux panneaux (1) assemblés forme ainsi une rainure en forme de V, voir figure 5. Furthermore, the upper face of the panel (1) may also have chamfers (13) at the level of the male stud (6b) and the female groove (7a) in order to participate in the general aesthetics of the panels (1), after assembly. Each chamfer (13) forms an angle between 2 ° and 20 ° relative to the upper face of the panel (1). The interface between the two assembled panels (1) thus forms a V-shaped groove, see Figure 5.
Il ressort de ce qui précède que l’invention fournit bien un panneau (1) pour la réalisation d’un revêtement de sol en pose libre, dont l’assemblage est facilité, tout en présentant une résistance au désassemblage horizontal et vertical optimale, ainsi qu’une esthétique satisfaisante. It appears from the above that the invention does provide a panel (1) for producing a free-standing floor covering, the assembly of which is facilitated, while having optimal resistance to horizontal and vertical disassembly, as well that a satisfactory aesthetic.
