Definitions

  • the present invention relates to the field of loose-lay floor coverings, and more particularly concerns a panel, preferably made of polyvinyl chloride, having the shape of a strip or slab for producing such a covering, the assembly of which is carried out according to an inclined kinematic on a first edge, and vertical on a second adjacent edge.
  • This type of panel is illustrated for example by the document EP 3 105 392 , and the document US 2013/0309441 . Both of these documents describe a panel having first and second complementary male/female coupling means on opposite pairs of sides for joining like panels together to form a floor covering.
  • the coupling means on the short sides have complementary means for resisting vertical disassembly, and external walls inclined relative to a vertical plane and oriented towards the inside of the panel. Assembly is achieved by tilting the panels along a long side and locking them vertically on a short side.
  • the installer When installing this type of floor covering, the installer first assembles the long side in an inclined assembly direction, for example at an angle of between 10° and 50° and, while maintaining the angle of inclination of the panel, he then slides it laterally towards the previous panel until it comes to a stop.
  • One of the aims of the invention is therefore to remedy the aforementioned drawbacks by proposing a panel for the production of a loose-lay floor covering, the assembly of which is carried out using inclined kinematics on one edge, then vertical kinematics on an adjacent edge.
  • Another object of the invention is to facilitate the assembly of two similar panels, and also to provide a panel having optimum resistance to horizontal and vertical disassembly, as well as satisfactory aesthetics.
  • the panel according to the invention has assembly kinematics inclined on one side, then by a pivoting movement of the panel, vertical on an adjacent side.
  • the fact that the male tenon has an external wall inclined relative to a vertical plane and towards the outside of the panel promotes vertical assembly during the rotation movement.
  • the installer positions the panels in abutment: the lower part of the male tenon rests 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 tenon in line with the groove to begin assembly. Then, advantageously, during pivoting, the two panels move closer to each other. The machining constraints for perfect surface contact of the panels are then easier to respect.
  • the presence of the lugs and notches also helps to optimize resistance to vertical disassembly, because the protruding angles of the lugs and notches allow for more effective locking than the bulges and cavities of the prior art.
  • the female external tenon comprises a chamfered portion at the lower face of the panel and forming an angle of between 2° and 20° relative to the lower face of the panel.
  • the chamfered portion allows the female tenon to be lowered 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.
  • the chamfered portion of the female tenon extends to the right of the inner upper edge of the female tenon, i.e. in particular to the right of the highest point of the female tenon from the ground. This feature allows better bending of the female tenon during assembly.
  • the male tenon has an internal wall inclined relative to a vertical plane and towards the outside of the panel.
  • the external and internal walls of the male tenon are inclined at an angle of between 1 and 45°, and preferably between 5° and 15°, and for example at the same angle.
  • the male tenon has a chamfered part at the upper face of the panel and forming an angle of between 2° and 20° relative to the upper face of the panel.
  • the male coupling means of the vertically assembled edges include two lugs or notches, and the female coupling means of the vertically assembled edges include two complementary notches or lugs.
  • the lug or notch is provided on the external wall of the male tenon and, in a complementary manner, the notch or lug is provided on an internal wall of the female groove.
  • the lug or notch is provided on the external wall of the female tenon and, in a complementary manner, the notch or lug is provided on an internal wall of the male groove.
  • the male coupling means of the inclined assembly edges comprise a tab projecting from the side wall, in particular orthogonally, of the panel and over the entire length of the edge
  • the female coupling means of the inclined assembly edges comprise a complementary groove provided in the side wall of the panel and over the entire length of the edge.
  • the tab comprises a vertically projecting lug
  • the complementary groove comprises a complementary notch forming, after assembly of two adjacent panels, stops against horizontal movement between two assembled adjacent panels.
  • the complementary groove of the female coupling means of the inclined assembly edges defines a flexible lower female tab intended to move apart during the inclined engagement of the tab of the male coupling means, then to resume its position after engagement to increase resistance to vertical and horizontal disassembly of two adjacent assembled panels.
  • the invention relates to a panel (1) having the shape of a blade or slab for producing a loose-lay floor covering.
  • the floor panel (1) according to the invention is preferably made of a plastic material, such as polyvinyl chloride, for example plasticized, and possibly comprising a mineral filler.

  • the panel (1) according to the invention can be obtained in any suitable plastic material.
  • the panel (1) is resilient, for example made from plasticized or rigid polyvinyl chloride.
  • the panel (1) has a core bonded to a decorative layer consisting of a decorative film bonded to a transparent surface layer.
  • the core may be single-layer or multi-layer, and made for example from plastic material such as polyvinyl chloride, polypropylene, polyurethane, thermoplastic polyurethane, polyethylene, polyethylene terephthalate, or any other suitable plastic material, and optionally comprising 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 rigidity of the core.
  • plastic material such as polyvinyl chloride, polypropylene, polyurethane, thermoplastic polyurethane, polyethylene, polyethylene terephthalate, or any other suitable plastic material, and optionally comprising 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 rigidity of the core.
  • the core may optionally be based on urea formaldehyde or melamine formaldehyde and wood, for example layers of medium density fiberboard (MDF) or high density fiberboard (HDF).
  • MDF medium density fiberboard
  • HDF high density fiberboard
  • Each layer may also be a layer of laminated wood, wood composite (WPC "wood plastic composite" in English).
  • Each layer may be compact or foamed.
  • the core may be made with a foamed layer of rigid polyvinyl chloride sandwiched between two layers of compact rigid polyvinyl chloride.

  • the panel (1) can have just as well a square shape.
  • the assembly of this type of panel (1) is done according to an inclined kinematics on a first edge (2), for example at an angle between 10° and 50°, and according to a vertical kinematics on a second adjacent edge (3).
  • the installer when installing this type of panel (1), the installer installs a first line of panels (1), assembling them side by side according to a vertical assembly kinematics. Then, the installer begins a second line of panels (1) by assembling a first panel (1), according to an inclined kinematics relative to the panels (1) of the previous line. The following panels (1) of the second line are assembled according to an inclined kinematics relative 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 a vertical kinematics.
  • the long sides are assembled according to an inclined kinematics, while the short sides are assembled according to a vertical kinematics.
  • the inclined assembly opposing edges (2) consist of an edge comprising male coupling means (4) provided from a side wall of the panel (1), and an opposing edge comprising complementary female coupling means (5) provided from a side wall of the panel (1).
  • the vertically assembled opposite edges (3) consist of an edge comprising male coupling means (6) provided from a lower face of the panel (1), and an opposite edge comprising complementary female coupling means (7) provided from an upper face of the panel (1).
  • the upper and facing edges of two panels (1) are preferably in contact for optimal aesthetics.
  • the male coupling means (4) of the inclined assembly edges (2) comprise a tab (8) projecting from the side wall of the panel (1) and over the entire length of the edge.
  • the female coupling means (5) of the inclined assembly edges (2) comprise a complementary groove (9) provided in the side wall of the panel (1) and over the entire length of the edge.
  • the tongue (8) comprises a lug (8a) projecting vertically
  • the complementary groove (9) comprises a complementary notch (9a) forming, after assembly of two adjacent panels (1), stops against horizontal movement between two adjacent assembled panels (1).
  • the tongue (8) may comprise a notch and the groove (9) may comprise a lug, without departing from the scope of the invention.
  • the engagement of the tongue (8) in the groove (9) is carried out according to an inclined kinematics, then by pivoting the panel (1), the tongue (8) is moved horizontally towards the bottom of the groove.
  • the groove (9) complementary to the female coupling means (5) defines a lower female tab (9b) flexible and intended to move away during the inclined engagement of the tab (8) of the male coupling means (4), then to resume its position after engagement to increase the resistance to vertical and horizontal disassembly of two adjacent assembled panels (1).
  • the male coupling means (6) of the vertically assembled edges (3) comprise a male groove (6a) extending along the edge and opening onto the lower face of the panel (1), so as to define a male tenon (6b).
  • 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 as to define a female tenon (7b).
  • 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 tenon (6b) has an external wall (6c) inclined relative to a vertical plane and towards the outside of the panel (1), at an angle of 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.
  • the installer sees the female groove (7a) and can therefore easily position the external wall (6c) of the male tenon (6b) at the level of the female groove (7a) to begin assembly.
  • the two panels (1) move closer to each other. This further facilitates the installation operation, and the machining constraints for having perfect surface contact of the panels (1) are also easier to respect.
  • the male tenon (6b) has an internal wall inclined relative to a vertical plane and towards the outside or the inside of the panel (1).
