Definitions

  • the present invention relates to a hard floor panel for floating installation with the formation of a floor panel composite, in particular a laminate floor.
  • Floor panels with tongue and groove profiles on the side edges for laying to form panels, such as laminate floors, are widely used and conventionally known.
  • the tongue and groove profiles make it easy to lay floor panels to floor coverings.
  • Such floor coverings can consist of wood fiber panels or plastic panels, for example.
  • the floor panels are provided with a decorative layer and an abrasion-resistant surface layer.
  • the tongue and groove profiles conventionally used have the disadvantage that gaps of different sizes are formed between the panels lying against one another. Dirt as well as moisture can penetrate into these gaps and lead to expansion or swelling of the base plate of the floor panel, in particular if wood-based panels are used as base plates. The expansion or swelling of the wood-based panel causes the surface layer to rise, so that the surface layer is exposed to increased abrasion.
  • a floor panel for realizing a floor covering is known, coupling parts in the form of a groove and a tongue being provided on the edges of two opposite sides of the panels. Tongue and groove are designed in such a way that when two or more floor panels are joined together, a tension force is exerted on one another, which the floor panels forces one another.
  • the tensioning force is brought about by an elastically bendable lip in the groove which is at least partially bent in the assembled state and in this way provides the aforementioned tensioning force.
  • WO 2016/113706 A1 describes a hard floor panel for floating installation with the formation of a floor panel composite, the opposite side edges each being provided with tongue and groove profiles and a tongue with a joining surface in the first side edge and a groove with an upper lip in the second side edge a joining surface is provided.
  • a floor panel in particular with a core made of a wood-based panel, a wood-based plastic panel or a plastic panel, with an upper side and a lower side and with side edges along the panel sides (i.e. along the long sides and transverse sides) is used for floating installation with the formation of a floor panel composite provided, whereby at least two floor panels are put together or connected to one another, the opposite side edges are provided with tongue and groove profiles, wherein a tongue and a joining surface are provided in a first side edge and a groove and a joining surface are provided in a second opposite side edge, wherein the tongue of the first side edge has an upper side and a lower side; wherein a projection with a contact surface is provided on the lower side of the spring; wherein the joining surface of the first side edge runs from the top of the floor panel to the upper tongue side and the joining surface is beveled; wherein the joining surface of the first side edge is inclined from the top of the floor panel inwardly away from the perpendicular away from the tongue so that the
  • tension and line pressure Due to the combination of tension and line pressure according to the invention, it is now possible to avoid the formation of gaps between adjacent floor panels, and thus to reduce the entry of moisture and dirt into the floor covering.
  • the line pressure results from the profile geometry and the pressure to be applied.
  • the tongue and groove preferably have shapes that are complementary to one another.
  • the protrusion on the lower side of the tongue extends along the lower lip of the groove and engages the recess of the lower lip of the groove when two panels are coupled.
  • the contact surfaces of the projection of the spring and the recess lie against one another.
  • the tongue is precisely positioned against the upper side and the lower side of the groove, a pressure P being exerted on the upper lip of the groove. This pressure is not only absorbed by the upper lip, but by the entire structure, since the pressure can be transmitted through the spring and the lower lip.
  • the clamping force by which the panels are joined and held is produced by the pressing pressure P.
  • bevel of the joining surfaces or joining edges is to be understood as a bevel or inclination of the joining surfaces or joining edges from the top of the panel inwardly away from the vertical away from the tongue or towards the groove.
  • the top of the panel and the respective joining surface of the side edges usually form a right angle (90 °); i.e. the top of the panel and the joining surface are arranged at right angles to one another.

  • the projection engages in the recess of the lower lip of the groove in the coupled state of two panels.
  • the angle of the contact surfaces of the protrusion of the spring and the recess of the lower lip is in Relation to the horizontal plane between 30 and 70 °. This angle is ideal to achieve an optimal compression of the floor panels and at the same time to allow easy engagement and assembly of the floor panels.
  • an additional space can form between the projection of the lower tongue side and the recess in the lower lip of the groove, which e.g. functions as a dust chamber.

  • the joining surface of the upper lip can have a rounded edge or bevel.
  • the bevel is provided at the point of contact between the upper lip of the groove and the top of the tongue and enables the floor panels to be easily assembled.
