Definitions

  • 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.
  • 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).
  • 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.
  • angling systems 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”).
  • 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.
  • 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.
  • 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.
  • 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.
  • Such a click system is for example described in the patent EP 1 026 341 B1 from UNILIN.
  • 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.
  • 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.
  • the thickness of the blade may be less than mm.
  • this objective is achieved by a panel according to claim 1.
  • 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.
  • at least one of the coupling elements is provided with a repositionable adhesive to secure two same panels joined by their respective coupling means.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • the term "decoupling moment” is the moment to be overcome in order to initiate the rotation of a panel in the disassembly direction.
  • 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.
  • the "click" effect of the panels according to the invention can be modulated in various ways.
  • 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.
  • 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.
  • 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),
  • the adhesive repositionable must have an immediate adhesion during the solicitation, and allow a large number of assemblies / disassemblies.
  • glues 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 ...
  • Hot-melt adhesives 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.
  • 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.
  • 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.
  • Such 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.
  • 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).
  • 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.
  • the geometry of the profile influences the click effect.
  • 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.
  • 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.
  • the adhesive deposits are preferably made directly on the panel material, e.g. HDF or MDF, and that these deposit
  • 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.
  • 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.
  • the first coupling means will be provided on a small and a large side
  • 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.
  • the shape of the panels and the number of edges may vary (eg polygonal shape), and the coupling means will be distributed adequately.
  • 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.
  • 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.
  • 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.
  • 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.
  • the panel according to the invention may have a multilayer structure, generally of the type: upper layer / support layer / counterbalance (if necessary).
  • 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.
  • the upper layer may be ceramic, or polymer.
  • the support may be fiber cement or resin, or other materials that lend themselves well to machining.
  • Fig.1 illustrates a cross-sectional view of a preferred embodiment of a panel 10 according to the invention.
  • 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.
  • the first coupling means 20 comprises a groove 24 and the second coupling means 22 is provided with a tongue 26.
  • 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.
  • 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.
  • 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.

  • 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.
  • the two locking surfaces are flat and preferably meet in the same plane, which forms an angle ⁇ (said locking angle) with the assembly plane (lower face 14 of the panel 10).
  • This angle ⁇ can be of the order of 35 to 70 °.
  • 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.
  • 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.
  • 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 '.
  • 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.
  • 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.

  • This type of glue is sometimes called “residual tack glue” or sticky adhesive.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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. ..
  • 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.
  • 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 .

It will be noted here that the hot-melt adhesive is in hot contact only with the surface on which it is deposited.
