Abstract

The panel (10) has edges with a groove (24) and a lug, where the groove cooperates with a corresponding lug (26`) of an edge of another panel (10`) to permit the coupling of the panels (10, 10`) in an assembling plane. An abutment (32) of the panel (10) has a surface (34) in contact with the surface of a locking groove (36) of the panel (10`), so as to lock the panels. The panel (10`) has ribbings (39`, 40`) whose free surface comprises a tack of 0.15 Newton/square millimeters. The ribbings come in contact directly with the material constituting the abutment. An independent claim is also included for a parquet flooring or floating floor comprising surface covering panel.

Description

Domaine TechniqueTechnical area

La présente invention concerne généralement les panneaux de revêtement de surface. Elle concerne plus particulièrement les parquets ou planchers dits flottants, et notamment les panneaux, communément appelés lames ou lattes, pour la réalisation de tels parquets et planchers.The present invention generally relates to surface coating panels. It relates more particularly floors or so-called floating floors, including panels, commonly called blades or slats for the production of such floors and floors.

Etat de la technique State of the art

Les parquets flottants connaissant depuis quelques années un grand essor. Par opposition aux parquets cloués ou collés pour lesquels la pose est délicate et exclusivement du domaine des spécialistes, les parquets flottants sont particulièrement appréciés pour leur simplicité d'installation (sur un revêtement de sol existant type moquette, carrelage ou vinyle, ou à même la dalle).Floating floors have been booming for a few years now. As opposed to nailed or glued parquet for which the installation is delicate and exclusively in the field of specialists, the floating floors are particularly appreciated for their simplicity of installation (on an existing flooring type carpet, tiles or vinyl, or even the slab).

Comme on le sait, les lames de parquet sont conventionnellement pourvues sur leurs chants d'éléments d'accouplement à rainure et languette qui sont destinés à la liaison par emboîtement de deux lames adjacentes au cours de l'assemblage du parquet.As is known, the floorboards are conventionally provided on their edges tongue and groove coupling elements which are intended for the interlocking connection of two adjacent blades during the assembly of the floor.

Parmi les différents systèmes proposés pour l'emboîtement des lames de parquet destinées à la réalisation des parquets flottants, ceux qui rencontrent le plus de succès auprès du consommateur et par conséquent tendent à se répandre au point d'évincer sans doute dans un avenir proche tous les autres, sont les systèmes appelés à « emboîtement angulaire » (ou « angling systems »). Dans ces systèmes à emboîtement angulaire, l'accouplement de deux lames de parquet se fait en engageant la lame à assembler avec un certain angle (en général 45°) par rapport à la lame déjà posée, puis en imprimant à cette lame un mouvement de rotation dont l'axe coïncide approximativement avec les arrêtes en contact des bords supérieurs des lames, pour l'amener dans le plan d'assemblage.Among the different systems proposed for the interlocking of parquet flooring boards for the realization of floating floors, those which meet the most successful with the consumer and consequently tend to spread to the point of probably ousting in the near future all the others are the so-called "angling systems" (or "angling systems"). In these angular interlocking systems, the coupling of two parquet strips is done by engaging the blade to be assembled at a certain angle (generally 45 °) with respect to the already laid blade, then by printing to this blade a movement of rotation whose axis coincides approximately with the edges in contact with the upper edges of the blades, to bring it into the assembly plane.

Un tel système est par exemple décrit dans le brevet US 4,426,820 délivré à Heinz Terbrack. Les lames de parquet ont une forme rectangulaire et sont conçues pour être assemblées par emboîtement de leurs chants longitudinaux opposés. Pour ce faire, un chant est pourvu d'un premier élément d'accouplement comprenant une rainure et l'autre d'un deuxième élément d'accouplement comprenant une languette et destiné à coopérer avec le premier élément d'accouplement d'une lame de plancher identique. Des moyens de verrouillage mécanique sont intégrés auxdits éléments d'accouplement de sorte à, lorsque deux lames de parquet sont accouplées dans le plan d'assemblage, empêcher ces lames de parquet de s'éloigner l'une de l'autre dans une direction perpendiculaire à celle desdits chants et parallèle au plan d'assemblage. Selon le profil d'accouplement présenté dans US 4,426,820 , la rainure du premier élément d'accouplement est délimitée par une lèvre supérieure et une lèvre inférieure. La lèvre inférieure s'étend au delà de la lèvre supérieure et comprend un élément de verrouillage en saillie. Le deuxième moyen d'accouplement comprend, outre la languette venant s'emboîter dans la rainure du premier moyen d'accouplement, une gorge de verrouillage coopérant avec l'élément de verrouillage saillant afin de bloquer la lame dans la direction transversale.Such a system is for example described in the patent US 4,426,820 delivered to Heinz Terbrack. The floorboards have a rectangular shape and are designed to be assembled by interlocking their opposite longitudinal edges. To do this, one edge is provided with a first coupling element comprising a groove and the other with a second coupling element comprising a tongue and intended to cooperate with the first coupling element of a blade of identical floor. Mechanical locking means are integrated in said coupling elements so that, when two floorboards are coupled in the assembly plane, preventing these floorboards from moving away from each other in a perpendicular direction to that of said songs and parallel to the assembly plane. According to the mating profile presented in US 4,426,820 the groove of the first coupling element is delimited by an upper lip and a lower lip. The lower lip extends beyond the upper lip and includes a projecting locking member. The second coupling means comprises, in addition to the tongue fitting into the groove of the first coupling means, a locking groove cooperating with the projecting locking element in order to block the blade in the transverse direction.

De nombreux perfectionnements ont été proposés depuis par les fabricants, dont le plus utile est communément appelé le « clic ». Le « clic » désigne un blocage partiel des lames entre elles après assemblage destiné à les maintenir solidaires en empêchant la rotation dans le sens du désaccouplement: si l'on cherche à désolidariser la dernière lame engagée, on n'y parviendra qu'en exerçant un effort certain. Ce verrouillage partiel présente 2 avantages:

  • Il facilite la pose en elle-même. En effet, avant d'assembler par leurs grands côtés les lames de la dernière rangée avec le parquet en cours de pose il convient de les assembler entre elles par leurs petits côtés (aux profils identiques aux grand côtés) et de les maintenir en place à l'aide de cales. L'effet « clic » s'exerçant sur les petits côtés permet de solidariser la rangée de lames, de limiter le nombre de cales à employer et de faciliter ainsi l'engagement de la rangée complète.
  • Il permet à l'utilisateur d'être certain que toutes les lames sont parfaitement engagées les unes dans les autres, puisqu'elles deviennent solidaires en raison du clic. Il sert donc en quelque sorte de témoin d'assemblage. Cette fonction a une réelle importance, essentiellement dans le cas des produits laminés à base de MDF (Medium Density Fibre) ou HDF (High Density Fibre) de faible épaisseur (par ex 6 mm) où les rainurages sont peu profonds et les parties en saillie fragilisées,
Many improvements have since been proposed by manufacturers, the most useful of which is commonly called the "click". The "click" means a partial blocking of the blades together after assembly to maintain them integral by preventing rotation in the direction of uncoupling: if one seeks to separate the last blade engaged, it will only succeed by exerting a certain effort. This partial lock has 2 advantages:
  • It facilitates the pose itself. Indeed, before assembling by their long sides the blades of the last row with the floor during installation it is advisable to assemble them by their small sides (with identical profiles to the large sides) and to keep them in place. using wedges. The "click" effect acting on the short sides makes it possible to secure the row of blades, to limit the number of shims to be used and thus to facilitate the engagement of the complete row.
  • It allows the user to be certain that all blades are fully engaged in each other, since they become interdependent because of the click. It serves as a kind of assembly witness. This function is of real importance, mainly in the case of rolled products based on MDF (Medium Density Fiber) or HDF (High Density Fiber) thin (eg 6 mm) where the grooves are shallow and the protruding parts weakened,

Cet effet de blocage partiel s'obtient en générant un frottement, et plus spécifiquement en jouant sur l'élasticité du matériau à la fin de la rotation lors de l'assemblage des planches.This partial locking effect is obtained by generating a friction, and more specifically by acting on the elasticity of the material at the end of the rotation during assembly of the boards.

Un tel système clic est par exemple décrit dans le brevet EP 1 026 341 B1 de la société UNILIN. Dans ce système, les éléments d'accouplement sont munis de moyens qui, à l'état insérés l'un dans l'autre de deux lames de parquet adjacentes, exercent une force de tension réciproque qui force les lames l'une vers l'autre. Cela est obtenu par une configuration particulière de la gorge de verrouillage et de la saillie de verrouillage, qui, à l'état assemblé, entraîne une déformation élastique de la lèvre inférieure du premier élément d'accouplement et procure ainsi la force de tension désirée.Such a click system is for example described in the patent EP 1 026 341 B1 from UNILIN. In this system, the coupling elements are provided with means which, when inserted into each other of two adjacent parquet strips, exert a mutual tension force which forces the blades one towards the other. other. This is achieved by a particular configuration of the locking groove and the locking projection, which, in the assembled state, results in an elastic deformation of the lower lip of the first coupling element and thus provides the desired tension force.

Ainsi, l'effet « clic » dans les systèmes connus résulte typiquement d'une sollicitation de l'élasticité intrinsèque des matériaux constituant les lames. Par ailleurs les efforts en jeu lors du clic vont solliciter plus ou moins fortement la lame en son endroit généralement d'épaisseur la plus faible.Thus, the "click" effect in known systems typically results from a solicitation of the intrinsic elasticity of the materials constituting the blades. Furthermore, the efforts involved in the click will be more or less strongly solicit the blade in its place generally of the lowest thickness.

Enfin, il convient de noter, et cela ressort évidemment des intérêts évoqués pour ce système, que cet effet est d'autant plus intéressant qu'il est manifeste.Finally, it should be noted, and this clearly shows the interests evoked for this system, that this effect is all the more interesting as it is obvious.

On peut donc aisément comprendre que dans le cas des produits de faible épaisseur, par exemple du type HDF, il devienne délicat de concilier résistance du matériau et intensité de l'effet « clic ». En effet pour de tels matériaux, l'épaisseur de la lame peut être inférieure au mm.It is therefore easy to understand that in the case of thin products, for example of the HDF type, it becomes difficult to reconcile resistance of the material and intensity of the "click" effect. Indeed for such materials, the thickness of the blade may be less than mm.

Objet de l'inventionObject of the invention

Il existe donc un besoin pour des lames de parquet du type à emboîtement angulaire, qui présentent un effet « clic » permettant de vérifier que les lames sont solidaires pendant la pose d'un parquet, mais qui ne risque pas d'endommager les lames de parquet.There is therefore a need for floorboards of the angular interlocking type, which have a "click" effect making it possible to check that the boards are secured during the laying of a floor, but which does not risk damaging the floorboards. parquet.

Description générale de l'inventionGeneral description of the invention

Conformément à l'invention, cet objectif est atteint par un panneau selon la revendication 1.According to the invention, this objective is achieved by a panel according to claim 1.

Le panneau selon la présente invention emploie des éléments d'accouplement conçus pour un emboîtement angulaire essentiellement sans déformation élastique, comparables en ce sens à ceux du système Terbrack classique. Selon un aspect important de l'invention, au moins un des éléments d'accouplement est pourvu d'un adhésif repositionnable afin de solidariser deux mêmes panneaux joints par leurs moyens d'accouplement respectifs. On obtient ainsi un emboîtement angulaire avec effet « clic » essentiellement sans déformation élastique des éléments d'accouplement et des panneaux, permettant un assemblage/désassemblage des panneaux sans compromettre leur intégrité.The panel according to the present invention employs coupling elements designed for angular interlocking essentially without elastic deformation, comparable in this sense to those of the conventional Terbrack system. According to an important aspect of the invention, at least one of the coupling elements is provided with a repositionable adhesive to secure two same panels joined by their respective coupling means. Thus an angular interlocking effect with "click" effect essentially without elastic deformation of the coupling elements and panels, allowing assembly / disassembly of the panels without compromising their integrity.

Le terme adhésif repositionnable désigne conventionnellement des adhésifs présentant une force adhésive, généralement appelée pégosité ou tack, suffisante pour une adhésion immédiate lors de la sollicitation. De tels adhésifs permettent un grand nombre de collages/décollages, normalement sans diminution de la pégosité. Un adhésif repositionnable présente une pégosité qui est généralement plus faible que celle de colles permanentes, et il n'y a pas d'accroissement de la force adhésive après mise en contact.The term repositionable adhesive conventionally means adhesives having an adhesive force, generally called tack or tack, sufficient for immediate adhesion during the stress. Such adhesives allow a large number of collages / takeoffs, normally without decreasing the tackiness. A repositionable adhesive has a tack that is generally lower than that of permanent adhesives, and there is no increase in adhesive strength after contacting.

Lors de l'emboîtement, l'adhésif repositionnable permet de solidariser immédiatement les panneaux, c'est-à-dire à les immobiliser l'un par rapport à l'autre. Le fait que les panneaux deviennent solidaires est, pour l'utilisateur, une indication d'un emboîtement correct ; il peut ensuite manipuler l'assemblage sans risque de séparation. Si l'utilisateur souhaite séparer des panneaux assemblés, il devra vaincre la force d'adhésion de la colle. En pratique, l'utilisateur ressentira une résistance à la séparation des panneaux rappelant celle des systèmes « clic » à déformation élastique.During the nesting, the repositionable adhesive makes it possible to immediately secure the panels, that is to say to immobilize them relative to each other. The fact that the panels become integral is, for the user, an indication of a proper interlocking; he can then manipulate the assembly without risk of separation. If the user wishes to separate panels assembled, it will have to overcome the adhesion force of the glue. In practice, the user will feel resistance to the separation of the panels reminiscent of the "click" systems with elastic deformation.

La présente invention concerne donc un panneau pour le revêtement de surfaces dont les éléments d'accouplement sont conçus pour permettre une utilisation s'apparentant aux systèmes « clic » connus. Toutefois, le panneau selon la présente invention est pourvu d'un « clic chimique », qui contrairement aux systèmes connus à « clic mécanique », ne repose pas sur une déformation élastique des éléments d'accouplement, mais sur un blocage (immobilisation des moyens d'accouplement respectifs l'un par rapport à l'autre) dû aux propriétés physico-chimiques des matériaux en contact.The present invention thus relates to a panel for the coating of surfaces whose coupling elements are designed to allow a use similar to known "click" systems. However, the panel according to the present invention is provided with a "chemical click", which unlike known systems with "mechanical click", does not rely on an elastic deformation of the coupling elements, but on a blocking (immobilization of the means mating relative to each other) due to the physicochemical properties of the materials in contact.

Conformément à un mode de réalisation préféré, le premier moyen d'accouplement comprend une lèvre supérieure et une lèvre inférieure délimitant la rainure, la lèvre inférieure s'étendant au-delà de la lèvre supérieure. En outre, les moyens de verrouillage mécanique comprennent:

  • un élément de verrouillage en saillie vers le haut sur la lèvre inférieure, l'élément de verrouillage ayant une première surface de verrouillage; et
  • une deuxième surface de verrouillage sur le deuxième moyen d'accouplement, laquelle est apte à coopérer avec la première surface de verrouillage d'un panneau similaire pour empêcher un déplacement perpendiculaire aux chants et parallèle au plan d'assemblage.
According to a preferred embodiment, the first coupling means comprises an upper lip and a lower lip delimiting the groove, the lower lip extending beyond the upper lip. In addition, the mechanical locking means comprise:
  • a locking member projecting upwardly on the lower lip, the locking member having a first locking surface; and
  • a second locking surface on the second coupling means, which is adapted to cooperate with the first locking surface of a similar panel to prevent displacement perpendicular to the edges and parallel to the assembly plane.

Dans cette variante, l'élément de verrouillage se trouve de préférence sur la lèvre inférieure au delà de ladite lèvre supérieure dans la direction perpendiculaire au chant. La deuxième surface de verrouillage est alors définie par une gorge de verrouillage dans le deuxième moyen d'accouplement, en arrière de la languette.In this variant, the locking element is preferably on the lower lip beyond said upper lip in the direction perpendicular to the edge. The second locking surface is then defined by a locking groove in the second coupling means, behind the tongue.

La première surface de verrouillage, de préférence plane, peut avoir un angle de verrouillage entre 35 et 70° par rapport à l'horizontale. Plus l'angle est important, meilleur est le blocage transversal..The first, preferably planar, locking surface may have a locking angle of between 35 and 70 degrees to the horizontal. The larger the angle, the better the cross lock.

Typiquement, pour un emboîtement angulaire, les moyens d'accouplement sont conçus de telle sorte que la languette d'un premier panneau puisse être insérée, avec une certaine inclinaison, dans la rainure d'un deuxième panneau, et que la butée du deuxième panneau soit insérable dans la gorge de verrouillage du premier panneau par un mouvement de rotation relatif entre ces panneaux autour d'un axe de rotation correspondant aux bords supérieurs des chants en contact. Avantageusement, l'adhésif repositionnable est prévu sur des surfaces des moyens d'accouplement qui ne sont sollicitées qu'à la fin de la rotation lors de l'assemblage, solidarisant ainsi immédiatement les lames et ne gênant pas l'emboîtementTypically, for an angular interlocking, the coupling means are designed so that the tongue of a first panel can be inserted, with a certain inclination, into the groove of a second panel, and that the stop of the second panel is insertable into the locking groove of the first panel by a relative rotational movement between these panels about an axis of rotation corresponding to the upper edges of the songs in contact. Advantageously, the repositionable adhesive is provided on surfaces of the coupling means which are only stressed at the end of the rotation during assembly, thus immediately securing the blades and not interfering with the interlocking

Pour le désassemblage de deux panneaux adjacents, il faudra donc vaincre la force d'adhésion de l'adhésif repositionnable. Dans la présente, on appelle « moment de désaccouplement » le moment à vaincre pour initier la rotation d'un panneau dans le sens de désassemblage.. De préférence, ce moment de désassemblage est de l'ordre de 3 à 9 N.m/m, de manière plus préférée d'environ 6 N.m/m. Ces valeurs sont de l'ordre de grandeur de celle observées sur les systèmes à « clic mécanique ».For the disassembly of two adjacent panels, it will therefore overcome the adhesive strength of the repositionable adhesive. In the present invention, the term "decoupling moment" is the moment to be overcome in order to initiate the rotation of a panel in the disassembly direction. Preferably, this disassembly moment is of the order of 3 to 9 Nm / m, more preferably about 6 Nm / m. These values are of the order of magnitude of those observed on "mechanical click" systems.

L'effet « clic » des panneaux selon l'invention peut être modulé de diverses façons, On peut notamment jouer sur les paramètres suivants : pégosité de l'adhésif ; géométrie/profil des moyens d'accouplement ; forme du dépôt adhésif ; nombre et position des dépôts adhésifs.The "click" effect of the panels according to the invention can be modulated in various ways. In particular, the following parameters can be used: tack of the adhesive; geometry / profile of the coupling means; form of the adhesive deposit; number and position of adhesive deposits.

La pégosité est fonction de l'adhésif (colle) reposftionnable sélectionné. Vu le moment de désassemblage recherché, on utilisera typiquement des adhésifs repositionnables avec une pégosité prédéterminée, comprise de préférence entre 0,05 et 0,30 N/mm2, de manière plus préférée de l'ordre de 0,15 N/mm2. Il va de soi que l'on parle ici de la pégosité de l'adhésif vis-à-vis du panneau qui va venir en contact avec l'adhésif lors de l'assemblage, et non pas de la force d'adhésion de l'adhésif par rapport à la surface du moyen d'accouplement sur laquelle il a été appliqué..The tack is a function of the selected adhesive (glue) selected. Given the desired disassembly moment, repositionable adhesives will typically be used with a predetermined tack, preferably between 0.05 and 0.30 N / mm 2 , more preferably on the order of 0.15 N / mm 2. . It goes without saying that we are talking here about the stickiness of the adhesive vis-à-vis the panel that will come into contact with the adhesive during assembly, and not the adhesion strength of the adhesive. adhesive relative to the surface of the coupling means to which it has been applied.

L'adhésif repositionnable sélectionné présente de préférence une excellente adhérence sur le matériau constituant le panneau (typiquement HDF, MDF ou bois pour la réalisation de parquets) lors de sa mise en oeuvre et conserver par la suite une pégosité qui lui permettra d'adhérer partiellement à ces même matériaux ou à d'autres matériaux de type polymères (la pégosité restant toujours moindre que l'adhérence lors de la mise en oeuvre), Bien entendu, l'adhésif repositionnable doit présenter une adhérence immédiate lors de la sollicitation, et permettre un grand nombre d'assemblages/désassemblages. Il existe une variété de colles repositionnables et il conviendra de faire un choix en fonction des matériaux, de la pégosité désirée, de la méthode d'application, etc...The repositionable adhesive selected preferably has excellent adhesion to the material constituting the panel (typically HDF, MDF or wood for the production of parquet) during its implementation and subsequently retain a stickiness that will allow it to partially adhere to these same materials or other polymer-like materials (the tackiness still remains less than the adhesion during the implementation), Of course, the adhesive repositionable must have an immediate adhesion during the solicitation, and allow a large number of assemblies / disassemblies. There is a variety of repositionable glues and it will be advisable to make a choice according to the materials, the desired tackiness, the method of application, etc ...

Les colles thermo-fusibles (« hot-melt ») sont particulièrement préférées, notamment pour leur facilité de mise en oeuvre. On l'appliquera sous forme de cordons aux endroits désirés des moyens d'accouplement. De préférence, on choisira des colles thermo-fusibles permettant de former, après refroidissement, des cordons avec une dureté (et cohésion) suffisante pour éviter que la colle ne flue vers l'autre panneau lors du désassemblage.Hot-melt adhesives ("hot-melt") are particularly preferred, especially for their ease of implementation. It will be applied in the form of cords at the desired locations of the coupling means. Preferably, thermo-fusible adhesives will be chosen to form, after cooling, cords with a hardness (and cohesion) sufficient to prevent the glue flue to the other panel during disassembly.

Avantageusement, l'adhésif repositionnable est prévu sur des surfaces des moyens d'accouplement qui ne sont sollicitées qu'à la fin de la l'emboîtement (fin de rotation) lors de l'assemblage, solidarisant ainsi immédiatement les panneaux et ne gênant pas l'emboîtement.Advantageously, the repositionable adhesive is provided on surfaces of the coupling means which are only stressed at the end of the nesting (end of rotation) during assembly, thus immediately joining the panels and not interfering nesting.

En outre, on peut positionner l'adhésif repositionnable sur des surfaces en regard des moyens d'accouplement qui ne sont pas en contact lorsque le panneau est accouplé à un même panneau. On pourra donc avantageusement prévoir des cordons de colle sur des surfaces non-fonctionnelles (qui ne servent pas à l'alignement ni au verrouillage) des moyens d'accouplement, comme par exemple au niveau de jeux d'assemblage.In addition, the repositionable adhesive can be positioned on facing surfaces of the coupling means that are not in contact when the panel is coupled to the same panel. It will therefore be possible advantageously to provide adhesive beads on non-functional surfaces (which are not used for alignment or locking) of the coupling means, for example at assembly games.

Un tel jeu d'assemblage existe typiquement en arrière de l'élément de verrouillage, qui comprend des surfaces en regard de la gorge de verrouillage légèrement espacées. Ces surfaces ne sont normalement pas en contact avec d'autres surfaces lors de l'emboîtement. La surface arrière de cette gorge de verrouillage, distincte de la deuxième surface de verrouillage, est donc avantageusement pourvue d'un ou plusieurs dépôts d'adhésif repositionnableSuch an assembly clearance typically exists behind the locking member, which includes slightly spaced facing surfaces of the locking groove. These surfaces are not normally in contact with other surfaces during nesting. The rear surface of this locking groove, distinct from the second locking surface, is therefore advantageously provided with one or more repositionable adhesive deposits.

Le positionnement de l'adhésif sur le deuxième moyen d'accouplement, et notamment dans la gorge de verrouillage, permet une exposition limitée des dépôts adhésifs et évite ainsi leur dégradation (poussières ou autres).Positioning the adhesive on the second coupling means, and especially in the locking groove, allows limited exposure of the adhesive deposits and thus prevents their degradation (dust or otherwise).

Pour éviter la remontée d'humidité par le dessous des panneaux, on prévoira avantageusement un dépôt d'adhésif repositionnable en partie inférieure du deuxième moyen d'accouplement. Un tel dépôt peut également être prévu en partie supérieure des moyens d'accouplement pour éviter la pénétration d'humidité depuis la face supérieure des panneaux.To prevent the rise of moisture from below the panels, it will advantageously provide a repositionable adhesive deposit in the lower part of the second coupling means. Such a deposit may also be provided in the upper part of the coupling means to prevent the penetration of moisture from the upper face of the panels.

Comme indiqué, la géométrie du profil influe sur l'effet clic. Dans ce contexte, on notera qu'un moment de désassemblage maximum peut être obtenu lorsque l'adhésif adhère à une surface de l'élément, de verrouillage qui est comprise dans un plan passant par l'axe de rotation lors du désaccouplement. De manière générale, les surfaces des moyens d'accouplement pourvues d'un dépôt d'adhésif repositionnable ou venant en contact avec l'adhésif à l'état assemblé sont de préférence planes.As shown, the geometry of the profile influences the click effect. In this context, it should be noted that a maximum disassembly moment can be obtained when the adhesive adheres to a surface of the locking element which is included in a plane passing through the axis of rotation during uncoupling. In general, the surfaces of the coupling means provided with an adhesive deposit repositionable or coming into contact with the adhesive in the assembled state are preferably flat.

On notera que les dépôts adhésif sont de préférence effectués directement sur le matériau constituant des panneaux, par ex. HDF ou MDF, et que ces dépôtNote that the adhesive deposits are preferably made directly on the panel material, e.g. HDF or MDF, and that these deposit

On notera encore que les surfaces des moyens d'accouplement qui vont entrer en contact avec un dépôt adhésif peuvent être dans un matériaux différent que celui du reste des moyens d'accouplement. Ces surfaces pourraient par exemple être recouvertes d'un polymère. Cela peut permettre d'éviter l'accumulation de particules du matériau constituant du panneau sur l'adhésif lors du désassemblage.It will also be noted that the surfaces of the coupling means which will come into contact with an adhesive deposit may be in a different material than that of the rest of the coupling means. These surfaces could for example be covered with a polymer. This can help prevent the accumulation of particles of the panel material on the adhesive during disassembly.

Le panneau selon l'invention a été particulièrement développé pour le revêtement de sols et notamment pour la réalisation de parquets. Il pourra donc avoir une forme classique (rectangulaire ou carrée) de lame de parquet. Conventionnellement, les premiers moyens d'accouplement seront donc prévus sur un petit et un grand côté, et les deuxièmes moyen d'accouplement seront prévus sur les autres petit et grand côté. Les dépôts d'adhésif repositionnable sont alors avantageusement effectués sur les moyens d'accouplement des petits et grands côtés.The panel according to the invention has been particularly developed for flooring and especially for the production of parquet floors. It can therefore have a classic shape (rectangular or square) floorboard. Conventionally, the first coupling means will be provided on a small and a large side, and the second coupling means will be provided on the other small and long side. The repositionable adhesive deposits are then advantageously performed on the coupling means of the small and long sides.

Suivant les applications, la forme du panneaux et le nombre de chants peuvent varier (par ex forme polygonale), et on répartira les moyens d'accouplement de manière adéquate.Depending on the applications, the shape of the panels and the number of edges may vary (eg polygonal shape), and the coupling means will be distributed adequately.

Le panneau selon l'invention peut être facilement fabriqué selon les techniques habituelles, qu'il s'agisse de bois massif, de contre-collé ou de stratifié. L'application d'une colle repositionnable thermo-fusible par exemple peut se faire facilement par des pistolets aux endroits prédéfinis des moyens d'accouplement, après usinage de ceux-ci.The panel according to the invention can be easily manufactured according to the usual techniques, be it solid wood, laminated or laminated. The application of a heat-fusible repositionable adhesive for example can be easily done by guns at predefined locations of the coupling means, after machining thereof.

Toutefois, le panneau selon l'invention peut être utilisé pour le recouvrement de surfaces autres que les sols, tels que les murs ou plafonds. Les panneaux peuvent donc être constitués de divers matériaux, suivant l'application.However, the panel according to the invention can be used for covering surfaces other than floors, such as walls or ceilings. The panels can be made of various materials, depending on the application.

Dans ce contexte, on appréciera que le panneau selon l'invention permet d'obtenir un effet « clic » même avec des matériaux qui, contrairement au bois, HDF ou aggloméré, ne possèdent pas de réelle élasticité. De tels matériaux, qui peuvent pour certaines applications se révéler de sérieux concurrents au HDF, sont par exemple les fibrociments ou certaines résines fortement chargée qui se prêtent bien à l'usinage (pour la réalisation d'un profil à emboîtement angulaire) mais n'ont aucune élasticité.In this context, it will be appreciated that the panel according to the invention makes it possible to obtain a "click" effect even with materials which, unlike wood, HDF or agglomerated, do not have real elasticity. Such materials, which for certain applications may prove to be serious competitors with HDF, are, for example, fibrocins or certain highly filled resins which lend themselves well to machining (for the production of an angular interlocking profile) but which do not have no elasticity.

Dans un grand nombre d'applications, le panneau selon l'invention peut avoir une structure multicouches, généralement du type: couche supérieure / couche support / contre-balancement (si nécessaire). Pour les parquets, la couche supérieure peut être en bois massif collée sur le support ou constituée d'une feuille de décor mélaminée (imitant le bois ou d'autres matériaux tels que la pierre, la céramique, etc.). La couche support peut être un panneau de particule (MDF, HDF, aggloméré), ou constituée de tasseaux en bois. Suivant les applications, la couche supérieure peut être en céramique, ou en polymère. Par ailleurs, comme évoqué plus haut, le support peut être en fibrociment ou en résine, ou d'autres matériaux se prêtant bien à l'usinage.In a large number of applications, the panel according to the invention may have a multilayer structure, generally of the type: upper layer / support layer / counterbalance (if necessary). For floors, the top layer can be solid wood glued to the support or made of a melamine-coated sheet (imitating wood or other materials such as stone, ceramic, etc.). The support layer may be a particle board (MDF, HDF, chipboard), or made of wooden battens. Depending on the applications, the upper layer may be ceramic, or polymer. Moreover, as mentioned above, the support may be fiber cement or resin, or other materials that lend themselves well to machining.

Description détaillée d'un mode de réalisation préféréDetailed description of a preferred embodiment

La Fig.1 illustre une vue en coupe transversale d'un mode de réalisation préféré d'un panneau 10 selon l'invention. Dans la présente variante, le panneau 10 est un panneau de revêtement de sol pour la réalisation d'un parquet (ou plancher) flottant. Ce panneau, qu'on appelle alors communément lame ou latte, a généralement une forme rectangulaire et comporte de manière classique une face supérieure 12, une face inférieure 14 opposée destinée à reposer dans le plan d'assemblage, ainsi que deux chants longitudinaux opposés 16 et 18 munis respectivement de moyens d'accouplement 20 et 22 pour être joint à d'autres panneaux similaires. Les petits côtés sont également munis de tels moyens d'accouplement.Fig.1 illustrates a cross-sectional view of a preferred embodiment of a panel 10 according to the invention. In the present variant, the panel 10 is a floor covering panel for producing a floating floor (or floor). This panel, which is then commonly called blade or batten, generally has a rectangular shape and conventionally comprises an upper face 12, an opposite lower face 14 intended to rest in the assembly plane, and two opposite longitudinal edges 16 and 18 respectively provided with coupling means 20 and 22 to be joined to other similar panels. The short sides are also provided with such coupling means.

Le premier moyen d'accouplement 20 comprend une rainure 24 et le deuxième moyen d'accouplement 22 est muni d'une languette 26. Conventionnellement, ces moyens d'accouplement 20 et 22 sont conçus de sorte à pouvoir coopérer ensemble pour l'assemblage du panneau 10 à d'autres panneaux de ce type.The first coupling means 20 comprises a groove 24 and the second coupling means 22 is provided with a tongue 26. Conventionally, these coupling means 20 and 22 are designed so as to cooperate together for the assembly of the coupling. panel 10 to other panels of this type.

La rainure 24 du premier moyen d'accouplement est délimitée par une lèvre supérieure 28 et une lèvre inférieure 30 qui s'étend au delà de la lèvre supérieure 28 dans la direction perpendiculaire au chant 16.The groove 24 of the first coupling means is delimited by an upper lip 28 and a lower lip 30 which extends beyond the upper lip 28 in the direction perpendicular to the edge 16.

Des moyens de verrouillage mécanique sont intégrés aux moyens d'accouplement 20 et 22, de sorte que, lorsque le panneau 10 est accouplé à un autre panneau identique dans le plan d'assemblage, ces moyens de verrôuillage empêchent les deux panneaux de s'éloigner l'un de l'autre dans une direction perpendiculaire à celle des chants 16, 18 et parallèle au plan d'assemblage. Dans la présente variante, les moyens de verrouillage comprennent un élément de verrouillage ou butée 32 en saillie vers le haut sur la lèvre inférieure 30, ladite butée 32 définissant une première surface de verrouillage 34. Les moyens de verrouillage comprennent en outre une gorge de verrouillage 36 dans le deuxième moyen d'accouplement 22, laquelle présente une deuxième surface de verrouillage 38. Comme pour la languette 26 et la rainure 24, la butée 32 et la gorge 36 s'étendent de préférence sur toute la longueur des chants.Mechanical locking means are integrated in the coupling means 20 and 22, so that when the panel 10 is coupled to another identical panel in the assembly plane, these locking means prevent the two panels from moving away from each other in a direction perpendicular to that of the edges 16, 18 and parallel to the assembly plane. In the present variant, the locking means comprise a locking element or stop 32 projecting upwards on the lower lip 30, said stop 32 defining a first locking surface 34. The locking means also comprise a locking groove. 36 in the second coupling means 22, which has a second locking surface 38. As for the tongue 26 and the groove 24, the stop 32 and the groove 36 preferably extend over the entire length of the edges.

Tel qu'illustré sur les Figures, la butée 32 est située sur le dessus de la lèvre inférieure 30, au delà de la lèvre supérieure 28 et donc hors de la rainure 24. La gorge 36 quand à elle est tournée vers le bas et située en arrière de la languette 26. La butée 30 et la gorge 36 sont conçues pour qu'à l'état accouplé (Fig.3), les première et deuxième surfaces de verrouillage 34 et 36, soient en contact pour bloquer les panneau assemblés dans la direction transversale des panneaux parallèlement au plan d'assemblage. Pour un verrouillage efficace, les deux surfaces de verrouillage sont planes et se rencontrent de préférence dans un même plan, qui forme un angle α (dit angle de verrouillage) avec le plan d'assemblage (face inférieure 14 du panneau 10). Cet angle α peut être de l'ordre de 35 à 70°.As shown in the figures, the stop 32 is located on the top of the lower lip 30, beyond the upper lip 28 and thus out of the groove 24. The groove 36 when it is facing down and located behind the tongue 26. The stop 30 and the groove 36 are designed so that in the coupled state (Fig.3), the first and second locking surfaces 34 and 36 are in contact to block the assembled panels in the transverse direction of the panels parallel to the assembly plane. For effective locking, the two locking surfaces are flat and preferably meet in the same plane, which forms an angle α (said locking angle) with the assembly plane (lower face 14 of the panel 10). This angle α can be of the order of 35 to 70 °.

Les moyens d'accouplement sont donc conçus de sorte à permettre un emboîtement angulaire. L'emboîtement de deux panneaux identiques est représenté sur la Fig.2, où un deuxième panneau 10' identique est joint au panneau 10 qui repose dans le plan d'assemblage. Pour cet accouplement, le panneau 10' est présenté avec un certain angle d'inclinaison et il est manipulé de sorte à insérer sa languette 26' dans la rainure 24 du panneau 10. La languette 26' est donc progressivement insérée dans la rainure 24 en déplaçant le panneau 10' et en adaptant son inclinaison, jusqu'à ce que les arêtes supérieures des chants entrent en contact en A. On imprime ensuite au deuxième panneau 10' un mouvement de rotation vers le bas, centré sur un axe passant par A, pour ramener le deuxième panneau 10' dans le plan d'assemblage et donc engager la butée 30 du premier panneau 10 dans la gorge 36' du deuxième panneau 10'.The coupling means are therefore designed to allow angular interlocking. The interlocking of two identical panels is shown in Fig.2, where a second identical panel 10 'is joined to the panel 10 which rests in the assembly plane. For this coupling, the 10 'panel is presented with a certain angle of inclination and is manipulated so as to insert its tongue 26' in the groove 24 of the panel 10. The tongue 26 'is therefore gradually inserted into the groove 24 by moving the panel 10' and adapting its inclination, until the upper edges of the edges come into contact at A. Then the second panel 10 'is printed downwardly, centered on an axis passing through A, to bring back the second panel 10 'in the assembly plane and therefore engage the stop 30 of the first panel 10 in the groove 36' of the second panel 10 '.

Selon un aspect important du présent panneau 10, les moyens d'accouplement sont avantageusement conçus pour que lors de l'accouplement, puis une fois deux panneaux adjacents joints par leur moyens d'accouplement respectifs, il n'existe essentiellement aucune déformation élastique.According to an important aspect of the present panel 10, the coupling means are advantageously designed so that during the coupling, then once two adjacent panels joined by their respective coupling means, there is essentially no elastic deformation.

Un autre aspect important est la présence d'un ou plusieurs dépôts d'adhésif repositionnable sur une portion de surface d'au moins l'un des moyens d'accouplement 20 et 22. Cela permet une adhésion immédiate entre les chants de deux panneaux adjacents lors de l'assemblage et donc de manipuler les panneaux sans qu'ils ne se désaccouplent; mais la nature repositionnable de l'adhésif permet la séparation (désaccouplement) ultérieure de deux panneaux adjacents en exerçant une force certaine. Le panneau selon l'invention est donc pourvu d'un « clic chimique » obtenu par cet adhésif repositionnable, qui procure le même confort d'utilisation que les systèmes à « clic mécanique » connus, mais ne résultant donc pas d'ùne déformation élastique des moyens d'accouplement.Another important aspect is the presence of one or more adhesive deposits repositionable on a surface portion of at least one of the coupling means 20 and 22. This allows immediate adhesion between the edges of two adjacent panels during assembly and thus to manipulate the panels without them uncoupling; but the repositionable nature of the adhesive allows the subsequent separation (uncoupling) of two adjacent panels by exerting a certain force. The panel according to the invention is thus provided with a "chemical click" obtained by this repositionable adhesive, which provides the same comfort of use as the known "mechanical click" systems, but does not therefore result from an elastic deformation coupling means.

On utilise avantageusement un adhésif (colle) repositionnable qui présente une excellente adhérence sur le matériau constituant la lame (généralement HDF, MDF ou bois) lors de sa mise en oeuvre et conserve par la suite un pouvoir d'adhésion (appelé tack) résiduel qui lui permettra d'adhérer partielle-ment à ces même matériaux où à d'autres matériaux de type polymères, ce pouvoir de collage résiduel restant toujours moindre que l'adhérence lors de la mise en oeuvre). Ce type de colle est parfois appelé « colle à tack résiduel » ou adhésif poissant. Il existe une variété de colles repositionnables et il conviendra de faire un choix en fonction des matériaux, du tack désiré, de la méthode d'application, etc...It is advantageous to use a repositionable adhesive (glue) which has excellent adhesion to the material constituting the blade (generally HDF, MDF or wood) during its use and subsequently retains a residual adhesion capacity (called tack) which it will allow it to partially adhere to these same materials or to other polymer type materials, this residual bonding power remaining always less than the adhesion during the implementation). This type of glue is sometimes called "residual tack glue" or sticky adhesive. There are a variety of repositionable glues and it will be necessary to make a choice depending on the materials, the desired tack, the method of application, etc ...

Dans la présente variante, l'accouplement est basé sur le profil Terbrack classique tel que présenté dans US 4,426,820 et qui ne visait donc pas une déformation élastique des éléments d'accouplement. Comme on peut le voir sur la Fig.3, l'alignement vertical entre deux panneaux adjacents est donc obtenu par l'emboîtement rainure/languette. Pour ce faire, il existe deux zones de contact dites "fonctionnelles":

  • entre la languette 26' et la lèvre supérieure 28 à l'intérieur de la rainure 24;
  • entre la languette 26' et la lèvre inférieure 30, à l'extérieur de la rainure 24 et avant la butée 32.
In the present variant, the coupling is based on the classical Terbrack profile as presented in US 4,426,820 and which therefore did not aim at an elastic deformation of the coupling elements. As can be seen in Fig.3, the vertical alignment between two adjacent panels is thus obtained by the groove / tongue interlocking. To do this, there are two so-called "functional" contact zones:
  • between the tongue 26 'and the upper lip 28 inside the groove 24;
  • between the tongue 26 'and the lower lip 30, outside the groove 24 and before the stop 32.

A l'état assemblé, le maintien dans la direction transversale est assuré par les moyens de verrouillage, et il existe deux autres surfaces de contact fonctionnelles:

  • au niveau des bords supérieurs des chants; et
  • entre les surfaces de verrouillage 34 et 38.
In the assembled state, the maintenance in the transverse direction is ensured by the locking means, and there are two other functional contact surfaces:
  • at the upper edges of the songs; and
  • between the locking surfaces 34 and 38.

En se référant à la Fig.3, un examen plus détaillé du profil des moyens d'accouplement permettra de voir comment distinguer un accouplement sans déformation élastique d'un accouplement avec déformation élastique. On comprendra qu'avec un tel profil, une condition d'engagement sans déformation des moyens d'accouplement est que les surfaces de verrouillage 34 et 38 n'opposent pas de résistance à la rotation requise pour l'emboîtement angulaire. Partant du principe que l'axe de rotation lors de l'accouplement passe par le point A de contact entre les arêtes supérieures des chants, il apparaît qu'un emboîtement par rotation sans résistance ne peut être obtenu que si l'angle de verrouillage α n'est pas supérieur à la pente de la tangente au cercle AB au point B. Au vu des côtes h et l indiquées sur la Fig.3 et de l'angle β entre le segment AB et la surface supérieure du panneau, on obtient la relation suivante: α 180 ° arctan h / l

Figure imgb0001
Referring to FIG. 3, a more detailed examination of the profile of the coupling means will make it possible to see how to distinguish a coupling without elastic deformation of a coupling with elastic deformation. It will be understood that with such a profile, a condition of engagement without deformation of the coupling means is that the locking surfaces 34 and 38 do not oppose resistance to the rotation required for the angular interlocking. Assuming that the axis of rotation during coupling passes through point A of contact between the upper edges of the edges, it appears that a rotational engagement without resistance can be obtained only if the locking angle α is not greater than the slope of the tangent to the circle AB at point B. Given the ribs h and l shown in Fig.3 and the angle β between the segment AB and the upper surface of the panel, we obtain the following relation: α 180 ° - arctan h / l
Figure imgb0001

Dans la présente variante, cette condition est vérifiée puisque l'angle α est tangent au cercle de rayon AB au point B. Un angle α plus faible répondrait donc à la même exigence, toutefois il est intéressant d'avoir un angle de verrouillage α le plus important possible pour améliorer le verrouillage transversal.In the present variant, this condition is verified since the angle α is tangent to the circle of radius AB at the point B. A lower angle α would therefore meet the same requirement, however it is advantageous to have a locking angle α the more important to improve the cross lock.

Comme indiqué plus haut, le profil des moyens d'accouplement du panneau 10 comprend un certain nombre de zones de contact fonctionnelles. Hors de ces zones fonctionnelles, il n'est pas requis que les moyens d'accouplement soient en contact. C'est par exemple cas dans la partie arrière de la butée 32, dans laquelle on prévoit de préférence un jeu de montage.As indicated above, the profile of the coupling means of the panel 10 comprises a certain number of functional contact zones. Outside these functional areas, it is not required that the coupling means be in contact. This is for example the case in the rear part of the abutment 32, in which a mounting set is preferably provided.

Dans la présente variante, l'adhésif repositionnable est prévu dans cette zone non-fonctionnelle à l'arrière de la butée 32, où il est déposé sous forme de cordons qui s'étendent de préférence sur toute la longueur du chant: un cordon 39, resp.39', au fond de la gorge 38 et un cordon 40, resp. 40', dans la région inférieure du deuxième élément d'accouplement 22. L'épaisseur du cordon correspond au jeu entre les moyens d'accouplement (ou est légèrement supérieure), de sorte qu'en fin d'assemblage, les cordons 39, 40 sont légèrement écrasés entre les surfaces correspondantes des moyens d'accouplement 20 et 22. Ce léger écrasement du cordon améliore l'adhérence de ce type de colle qui présente généralement une certaine sensibilité à la pression.In the present variant, the repositionable adhesive is provided in this non-functional area behind the abutment 32, where it is deposited in the form of beads which preferably extend over the entire length of the edge: a cord 39 , resp.39 ', at the bottom of the groove 38 and a cord 40, resp. 40 ', in the lower region of the second coupling element 22. The thickness of the cord corresponds to the clearance between the coupling means (or is slightly greater), so that at the end of assembly, the cords 39, 40 are slightly crushed between the corresponding surfaces of the coupling means 20 and 22. This slight crushing of the bead improves the adhesion of this type of glue which generally has a certain sensitivity to pressure.

On remarquera encore que les dépôts adhésif 39, 39', 40, 40' sont de préférence effectués sur des surfaces planes de la gorge 36, et que les surfaces de la butée 32 qui vont entrer en contact avec les dépôts adhésifs sont également planes. Par ailleurs, alors que dans la présente variante les dépôts adhésifs 39, 39', 40, 40' viennent en contact, lors de l'assemblage, directement avec le matériau constituant de la butée 32, on pourrait prévoir un revêtement polymère approprié sur cette butée 32 afin d'éviter (ce qui peut être intéressant pour certains matériaux) que le cordon n'entraîne quelques particules de la butée lors du désassemblage.It will further be noted that the adhesive deposits 39, 39 ', 40, 40' are preferably made on flat surfaces of the groove 36, and that the abutment surfaces 32 which come into contact with the adhesive deposits are also flat. Moreover, while in the present variant the adhesive deposits 39, 39 ', 40, 40' come into contact, during assembly, directly with the constituent material of the abutment 32, an appropriate polymeric coating could be provided on this stop 32 in order to avoid (which may be interesting for some materials) that the cord causes some particles of the stop during disassembly.

Il est à noter que le blocage des panneaux par l'adhésif est réalisé sans effort, ou juste avec un effort minimal assurant le contact étroit de l'adhésif avec le matériau en regard. Ce sont les propriétés physico-chimiques des matériaux en contact qui assurent le blocage des panneaux, lesquels ne sont alors soumis à aucunes contraintes fortes susceptibles d'endommager les moyens d'accouplement ou plus généralement le panneau. La nature même des colles repositionnables permet un grand nombre d'accouplements et désaccouplements sans en altérer l'efficacité.It should be noted that the blocking of the panels by the adhesive is achieved without effort, or just with minimal effort ensuring the close contact of the adhesive with the material opposite. It is the physicochemical properties of the materials in contact which ensure the blocking of the panels, which are then not subjected to any strong stresses likely to damage the coupling means or more generally the panel. The very nature of repositionable glues allows a large number of couplings and uncoupling without altering their effectiveness.

L'effet « clic » recherché peut être modulé en jouant sur les paramètres suivants: pégosité de l'adhésif ; géométrie du profil d'accouplement ; position du/des cordon(s) adhésif(s); forme et dimensions du cordon adhésif; et nombre de cordons. On comprendra que ce qui est important pour l'effet clic est la pégosité par rapport à la surface venant en contact avec le dépôt adhésif lors de l'emboîtement, et non la force adhésive par rapport au matériau sur lequel le dépôt adhésif a été fait..The desired "click" effect can be modulated by adjusting the following parameters: stickiness of the adhesive; geometry of the coupling profile; position of the adhesive cord (s); shape and dimensions of the adhesive bead; and number of cords. It will be understood that what is important for the click effect is the tackiness with respect to the surface coming into contact with the adhesive deposit during the nesting, and not the adhesive force with respect to the material on which the adhesive deposit was made. ..

De préférence, on jouera sur ces divers paramètres pour obtenir un effet « clic » lors du désassemblage des panneaux selon l'invention qui s'apparente à celui d'un « clic » mécanique. Une campagne de mesure réalisée sur divers systèmes à « clic mécanique » connus a permis de déterminer que le moment moyen à exercer pour séparer deux lames voisines est de l'ordre de 6 N.m pour une longueur de chant de 1 m (noté 6 N.n/m).Preferably, one will play on these various parameters to obtain a "click" effect when disassembling panels according to the invention which is similar to that of a mechanical "click". A measurement campaign carried out on various known "mechanical click" systems made it possible to determine that the average moment to exert to separate two adjacent blades is of the order of 6 Nm for a length of edge of 1 m (denoted 6 Nn / m).

Ainsi, on jouera de préférence sur les différents paramètres énoncés ci-dessus pour que l'adhésion entre deux panneaux selon l'invention soit telle qu'un moment (appelé moment de désassemblage) compris entre 3 et 9 N.m/m, plus préférablement de l'ordre 6 N m/m, soit requis pour initier la rotation d'un panneau hors du plan d'assemblage.Thus, preference will be given to the various parameters stated above so that the adhesion between two panels according to the invention is such that a moment (called disassembly moment) of between 3 and 9 Nm / m, more preferably the order 6 N m / m, is required to initiate the rotation of a panel out of the assembly plane.

Un tel moment de désassemblage peut être obtenu avec des colles repositionnables ayant une pégosité entre 0,05 et 0,3 N/mm2, de préférence d'environ 0,15 N/mm2.Such a disassembly moment can be obtained with repositionable glues having a tack between 0.05 and 0.3 N / mm 2 , preferably about 0.15 N / mm 2 .

On notera, à titre comparatif, que si le panneau 10, 10' n'était pas muni de dépôts d'adhésif repositionnable, le moment de désassemblage de ce panneau serait uniquement fonction de son poids, puisque le profil d'accouplement ne se déforme pas lors du désassemblage.It should be noted, for comparison, that if the panel 10, 10 'was not equipped with repositionable adhesive deposits, the disassembling moment of this panel would depend solely on its weight, since the coupling profile does not deform during disassembly.

Dans le mode de réalisation illustré aux Figs.1 à 3, on emploie une colle repositionnable déposée sous forme de cordon. Il s'agit de préférence d'une colle thermo-fusible (hot-melt), qui est appliquée à chaud. Selon leur viscosité à chaud, de telles colles peuvent être déposées sous forme de cordons, de films ou de cordons aplatis. Leur application se fait au moyen de pistolets sur lesquels s'adaptent des buses de différents diamètres. On notera ici que la colle thermo-fusible n'est en contact, à chaud, qu'avec la surface sur laquelle elle est déposée. Cette colle se solidifie et présente ensuite une surface libre ayant une pégosité qui provoque l'adhésion immédiate, en exerçant une certaine pression, de la butée 32, mais ne fixe pas de manière définitive les panneaux ensemble.In the embodiment illustrated in FIGS. 1 to 3, a repositionable adhesive deposited in the form of a bead is used. It is preferably a hot-melt glue (hot-melt), which is applied hot. Depending on their hot viscosity, such glues can be deposited in the form of cords, films or flattened cords. Their application is made by means of pistols on which fit nozzles of different diameters. It will be noted here that the hot-melt adhesive is in hot contact only with the surface on which it is deposited. This glue solidifies and then has a free surface having a stickiness which causes the immediate adhesion, exerting a certain pressure, of the abutment 32, but does not definitively fix the panels together.

Les colles thermo-fusibles sont généralement à base de polyoléfines, de polyuréthane (PU), d'éthyle vinyle acétate (EVA), polyacétate de vinyle (PVAC), de polybutyral de vinyle (PVB), etc. Pour une application avec des moyens d'accouplement en HDF, on pourra utiliser la colle thermo-fusible connue sous le nom INSTAWELD 6615 E (fabriquée par NATIONAL Starch & Chemical).Thermal-fusible adhesives are generally based on polyolefins, polyurethane (PU), ethyl vinyl acetate (EVA), polyvinyl acetate (PVAC), polyvinyl butyral (PVB), etc. For application with coupling means made of HDF, the hot-melt glue known as INSTAWELD 6615 E (manufactured by NATIONAL Starch & Chemical) can be used.

Alternativement, des colles applicables à température ambiante (ex. émulsions acrylique) peuvent être employées. Ces colles sont par exemple déposées sous forme de film par léchage sur un cylindre de dimensions adaptées. Ce type de colle nécessite des contacts de surfaces de dimensions plus importantes.Alternatively, adhesives applicable at room temperature (eg acrylic emulsions) can be used. These glues are for example deposited in film form by licking on a cylinder of suitable dimensions. This type of glue requires contact surfaces of larger dimensions.

On notera encore que ce qu'il importe est que la colle utilisée pérmette la formation d'un dépôt adhésif ayant le comportement d'un adhésif repositionnable vis-à-vis du matériau qui va entrer en contact avec celui-ci lors de l'emboîtement. Ce type de dépôt peut éventuellement être obtenu avec des colles qui ne sont pas connues (commercialisées) en tant que colles repositionnables, et entrent donc également dans le cadre de la présente invention.It will also be noted that what is important is that the glue used perimeter the formation of an adhesive deposit having the behavior of a repositionable adhesive vis-à-vis the material that will come into contact with it during the nesting. This type of deposit may possibly be obtained with glues that are not known (marketed) as repositionable glues, and therefore also fall within the scope of the present invention.

Comme indiqué plus haut, la géométrie du profil d'accouplement et la position des cordons de colle influent sur l'effet clic ressenti par l'utilisateur. La Fig.4 montre une variante du mode de mode de réalisation des Figs.1 à 3, dans lequel les profils de la butée 132 et de la gorge de verrouillage 136 ont été modifiés pour accroître l'effet « clic». Comme on le voit, la surface arrière de la butée 132 (après la surface de verrouillage 134 en s'éloignant de la rainure 124) n'est plus horizontale mais est inclinée de sorte que sa surface soit comprise dans un plan passant par A, l'arête supérieure des chants en contact.As indicated above, the geometry of the coupling profile and the position of the adhesive beads affect the click effect felt by the user. The Fig.4 shows a variant of the embodiment of Figs.1 to 3, wherein the profiles of the abutment 132 and the locking groove 136 have been modified to increase the "click" effect. As can be seen, the rear surface of the abutment 132 (after the locking surface 134 away from the groove 124) is no longer horizontal but is inclined so that its surface is included in a plane passing through A, the upper edge of the songs in contact.

Dans cette configuration, les surfaces de collage sont perpendiculaires à la direction de désassemblage des panneaux, ce qui permet de maximiser l'intensité du moment de désassemblage requis pour séparer les lames 110 et 110' par rotation dans le sens anti-horaire. Ainsi, pour un cordon de mêmes caractéristiques qu'en Fig.3, la configuration de la Fig.4 permet d'intensifier l'effet « clic».In this configuration, the bonding surfaces are perpendicular to the disassembling direction of the panels, thereby maximizing the amount of disassembly moment required to separate the blades 110 and 110 'by counter-clockwise rotation. Thus, for a cord having the same characteristics as in FIG. 3, the configuration of FIG. 4 makes it possible to intensify the "click" effect.

On dispose également d'une plus grande surface pour appliquer le cordon.There is also a larger area to apply the bead.

Enfin, on notera la structure multicouches du panneau 10, qui comprend (voir Fig.1) une couche supérieure 42, une couche support 44 et un contre-balancement 46. Dans la présente variante, la couche supérieure 42, en bois massif, est contrecollée sur la couche support. La couche support 44 est en MDF ou HDF. Le contre-balancement 46 est à base de cellulose imprégnée de résine.Finally, note the multilayer structure of the panel 10, which comprises (see FIG. 1) an upper layer 42, a support layer 44 and a counterbalance 46. In the present variant, the upper layer 42, made of solid wood, is laminated on the support layer. The support layer 44 is made of MDF or HDF. The counterbalance 46 is based on cellulose impregnated with resin.

Suivant les applications, la couche supérieure peut être un décor mélaminé (stratifié) ou une céramique. Le support peut être en fibrociment ou résine chargée ou d'autres matériaux se prêtant bien à l'usinage. Le contre-balancement n'est pas toujours nécessaire.Depending on the application, the upper layer may be a melamine decor (laminate) or a ceramic. The support may be of fiber cement or filled resin or other materials suitable for machining. Counterbalancing is not always necessary.
