Definitions

  • the invention relates to a floor covering consisting of a plurality of panels identical in their structure with two long side edges and two short side edges, as well as a panel for use in this floor covering.
  • Floor coverings can be made from real wood panels as wooden parquet or from wood-based panels as laminate flooring.
  • DE 202 08 058 U1 describes a laminate system for laying as a floor, which consists of right and left panels that are axially symmetrical to one another, with long and short side edges, each of which has a homogeneous, continuous decoration on its surface.
  • the grooves and tongues for the right and left panels accordingly, they can be laid not only in rows or like a mosaic, but also perpendicular laying of the end areas of the panels that touch each other, such as in a herringbone pattern.
  • the underside of the panels can be profiled to improve the adhesive effect of a PU adhesive used during installation by increasing the adhesive surface. This profile can be in the form of corrugations, slots or elevations and valleys.
  • DE 202019 103 690 U1 discloses a floor panel with long and short side edges, which has a coupling part on each long edge and on each short edge, which makes it possible to couple the panel to another identically designed panel.
  • the coupling part on one long side edge comprises a tongue and a downwardly directed locking groove.
  • the coupling parts on the opposite side edge and on the two short Side edges each comprise a groove and a locking lip.
  • the locking lip delimits the respective groove downwards and comprises an upwardly directed locking element.
  • the tongue is configured to cooperate with the groove on each of the other long side edges and the short side edge of another such panel to effect a vertical locking between the respective edges.
  • This configuration of the coupling and locking means enables the panels to be connected to one another in a floating manner to form a floor covering. Gluing to the subfloor is not necessary.
  • WO 2004/063491 A1 discloses a floor covering consisting of panels which have at least long and short side edges which are provided with coupling parts so that they can form a herringbone pattern when joined together, with the side edges of the panels coinciding with transition edges of the herringbone pattern. This is intended to prevent annoying seams at the transitions.
  • the coupling means are provided on all side edges in such a way that left and right panels are formed in order to be able to produce the herringbone pattern.
  • the coupling means can be used to create a pre-tension at the connection points, which is intended to ensure that the panels remain connected to one another even if they are not glued to the subfloor.
  • WO 2005/054599 A1 discloses a floor covering with a herringbone pattern, for the formation of which three different panel types A, B, C are used.
  • the panel types A are laid in a first direction and the panel types B in a second direction, which runs at right angles to the first direction.
  • the third panel types C are laid between two first panel types A or two second panel types B and connected to them.
  • EP 1 730 366 B1 discloses panels for use as floor coverings, with which a wide variety of installation options can be implemented.
  • the long side edges and the short side edges are contoured to enable a connection to an adjacent panel at each edge.
  • One long side edge has a groove and the opposite long side edge has a corresponding tongue.
  • the contours of the short side edges are each provided with an undercut to allow engagement of the tongue of the long side edge with the contour of the short side edge of an adjacent, identical panel element.
  • a step is provided on each short side edge following the undercut and an engagement is provided between the lower part on one long side edge and the step to allow connection between the groove of the long side edge and each short edge of an adjacent, identical panel.
  • the panels are not made of solid wood but of a laminate with a core made of wood-based material, internal stresses arise when the necessary individual material layers are pressed together to form a large-format wood-based panel due to the high pressing pressures and the different materials in the individual layers.
  • the individual panels are sawn out of the large-format panel and the side edges are then profiled to create the coupling elements. If the panels have a usual thickness of 8 to 12 mm, they are stable enough to withstand the internal stresses.
  • the object of the invention is to create a floor covering consisting of a plurality of panels identical in their structure with two long and two short side edges, which can be realized in particular with thin panels with a thickness of less than 5 mm.
  • the problem is solved by gluing each panel to the substrate and, in addition, the panels, which are adjacent to each other with their long side edges, are mechanically connected to each other via a first guide rail provided on only one long side edge.
  • a mechanical connection is understood in particular to mean that the two panels connected by this mechanical connection are mechanically locked in at least one direction. This means that the two panels cannot be separated from one another by moving one of the two panels in this one direction.
  • One possible mechanical connection is achieved, for example, by a tongue-and-groove connection.
  • the guide rail in this case is the tongue, which is inserted into a groove in a side surface of an adjacent panel to create the mechanical connection. It is then not possible to separate the two panels from one another by moving one of the two panels in a direction perpendicular to the top of the panels. In this state, the two panels are locked in this direction, which can also be referred to as the vertical direction.
  • the top of a panel is the visible side that faces away from the substrate.
  • the panels are connected to a respective neighboring panel via the guide rail, which is only present on one long side, and are preferably locked in a vertical direction.
  • the mechanical connection is therefore created between a first long side edge of a first panel and a second long side edge of the neighboring panel. Due to the mechanical locking, it is preferably not possible, when the floor covering is installed, to lift the first panel in the area of the first long side edge without also lifting the neighboring panel in the area of its second long side edge, i.e. moving it in a vertical direction.
  • a guide rail for mechanically connecting a panel to an adjacent panel engages in a groove located on the second long side edge of the adjacent panel.
  • a groove is a recess extending along the second long side edge that extends between an upper lip and a lower lip.
  • the upper lip extends on the side of the groove facing the top side and the lower lip extends on the side of the groove facing the bottom side and the substrate. It is not necessary, but in some embodiments advantageous, if the upper lip and the lower lip are the same length. In other embodiments, the upper lip and the lower lip are of different lengths.
  • a PU adhesive as is well known in the art, can be used as the adhesive.
  • the guide rail is preferably formed in one piece on the long side edge and engages in a corresponding groove on the opposite side edge of another panel. An additional profiling of the A guide rail with locking devices is not necessary. This makes production cost-effective.
  • a guide rail in the sense of the present invention is preferably designed as a tongue of a tongue-and-groove connection. It is sufficient if only one of the two long side edges of the panel has such a tongue and the opposite second long side edge and the two short side edges of the panel do not have a tongue, but preferably a groove corresponding to the tongue.
  • the panels that are adjacent to one another with their short side edges can also be mechanically connected to one another via a second guide rail provided on only one short side edge.
  • the second guide rail can also be formed in one piece on the short side edge of a panel and then engage in a congruently formed groove on the opposite side edge of another panel.
  • additional profiling of the guide rail with locking means is not necessary.
  • the first panels are laid with their long side edges in a first direction and the second panels are laid with their long side edges in a second direction.
  • the first direction and the second direction are at right angles to each other and all panels whose long side edges are adjacent to each other are mechanically connected to each other via the first guide rails provided on only one long side edge.
  • the panels whose short side edges are adjacent to the long side edges of the panels are each mechanically connected to another panel at their first short side edges via the first guide rail and there is no mechanical connection between their second short side edges and another panel.
  • all of the panels are identical.
  • the short edges are only provided with grooves, so that a particularly simple design of a panel is possible.
  • the first guide rail in the long side edge engages in a groove in the opposite short side edge of another panel. There is no connection to another panel on the opposite short side edge.
  • the additional mechanically applied forces are sufficient to prevent a panel from "rising up”. This means that panels with a maximum thickness of 5 mm can be used even with a herringbone installation.
  • the tongue and groove which are arranged on the opposite long side edges and, in some embodiments, also on the opposite short side edges of the panels, are designed such that they can be inserted into one another in a direction parallel to the surface.
  • two panels can be arranged next to one another on a floor, for example, so that a side edge of the first panel provided with a guide rail faces a side edge of the second panel not provided with a guide rail.
  • the floor is coated with an adhesive or glue so that the adhesive or glue is located between the panels and the floor. The two panels can then be moved towards one another on the floor, i.e. parallel to their surface, so that the guide rail of one panel is inserted into the correspondingly designed side edge of the other panel.
  • the part of the floor to be covered with the floor covering is first coated with adhesive or glue.
  • the panels are then arranged on the floor, preferably in the correct alignment with one another, and then moved to their final position on the floor, i.e. parallel to their surface.
