Definitions

  • the invention relates to a panel for cladding a surface, in particular a floor panel for cladding a floor area of a building space, with a panel core which consists of a flat panel surface, a flat panel undersurface spaced from this and parallel to it and four panel side surfaces connecting the panel surface to the panel undersurface is enclosed, with mutually complementary coupling elements in the form of an upper coupling element and a lower coupling element being arranged on two opposite panel side surfaces, which are configured in such a way that they enable a coupling of a first such panel to a second such panel by means of a relative movement of the upper coupling element of the first Allow panels to the lower coupling element of the second panel out, the upper coupling element has a wedge-shaped projection at its distal end and the lower coupling element aufwei a counter surface st, which rests against the wedge-shaped projection in the coupled state of two panels, so that the wedge-shaped projection together with the mating surface form a first coupling section of the coupling elements, the upper coupling element
  • Such a panel thus always has a lower coupling element and an upper coupling element, with the terms “lower” and “upper” referring to the fact that when the panels are being assembled, an upper coupling element of a panel to be assembled is attached to a lower coupling element of an already assembled and on the panel lying on the ground is pressed on.
  • the wedge-shaped projection of the upper coupling element is pressed onto a mating surface of the lower coupling element which runs obliquely to the ground.
  • the lower coupling element is spread open in the area of the locking receptacle by the penetrating locking element of the upper coupling element.
  • the upper coupling element is spread open in the region of the locking receptacle by the penetrating locking element of the lower coupling element.
  • Fluid strength is understood to mean the ability of a composite of the panels to resist the passage of fluid, such as water, from the top of the panels and between adjacent panels to the bottom of the panels and, in the best case, to prevent this entirely.
  • fluid such as water
  • a panel for cladding a surface in this respect, in particular a floor panel for cladding a floor area of a building space, with a panel core of a flat panel surface, one of this spaced-apart and parallel to this flat panel undersurface and four panel side surfaces connecting the panel surface to the panel undersurface, wherein mutually complementary coupling elements in the form of an upper coupling element and a lower coupling element are arranged on two opposite panel side surfaces, which are designed in such a way that they have a enable a first such panel to be coupled to a second such panel by means of a relative movement of the upper coupling element of the first panel towards the lower coupling element of the second panel, the upper coupling element has a wedge-shaped projection at its distal end and the lower coupling element has a mating surface which in the coupled state of two panels rests against the wedge-shaped projection, so that the wedge-shaped projection together with the mating surface form a first coupling portion of the coupling elements, the upper Koppelel ement has
  • the surface of the locking receptacle and the surface of the locking element each have a corrugated structure, these corrugated structures being complementary to one another.
  • the fact that the corrugated structures are complementary to one another means that the shape of these corrugated surfaces is such that they lie flat against one another in the coupled state of two panels, which is achieved by the surface shapes of the locking receptacle of the locking element corresponding to one another. That's where the locking mount is has a trough, the locking element is provided with a crest, and vice versa. In this way, an interlocking of the two surfaces is practically achieved. This makes the interface between the latch receiver and the latch member larger than flat surfaces, ultimately making it more difficult for fluid to pass between the latch receiver and the latch member. In this way, an even higher fluid resistance of a composite panel consisting of such panels can be achieved.
  • corrugated structures in the locking receptacle and the locking element run perpendicularly to the panel side faces that have the mutually complementary coupling elements. It has been shown that particularly good resistance to fluids can be achieved in this way.
  • shape of the corrugated structures can follow various forms. According to a preferred development of the invention, however, it is provided that the wave structures in the locking receptacle and the locking element run sinusoidally.
  • the wave structures have at least four wave crests, preferably at least five wave crests, very preferably at least six wave crests. It has been shown that even such a small number of wave crests leads to a significant improvement in fluid resistance. Furthermore, it is preferred that the height difference between the wave crests and the wave troughs is between a maximum of 7% and a minimum of 1% of the total thickness of the panel given by the distance between the panel surface and the panel undersurface.
  • the invention allows the surfaces of the locking element and the surface of the locking receptacle as a whole, that is to say without taking the corrugation structure into account, both to be essentially planar.
  • the wave structures practically oscillate around a plane plane.
  • the surfaces of the locking element is generally convex perpendicular to the panel side faces having the mutually complementary coupling elements and the surface of the locking receptacle is generally concave perpendicular to the panel side faces having the mutually complementary coupling elements.
  • surfaces are convex or concave overall, this means the shape of the surfaces without the wave structures.
  • the wave structures mean that both surfaces repeatedly have convex or concave areas locally.
  • the surface of the locking element according to the preferred development of the invention described here is curved outwards, i.e. in the locked state of two panels towards the surface of the locking receptacle, while the surface of the locking receptacle is correspondingly retracted so that it touches the surface of the locking element is adjusted.
  • the surfaces of the locking element and the surface of the locking receptacle run perpendicularly to the side surfaces of the panel, which have the mutually complementary coupling elements, apart from the corrugated structures, in the shape of a segment of a circle, with the radius of the surface of the locking element and the surface of the locking receptacle being in range from 85% to 95% of the total thickness of the panel given by the distance between the panel surface and the panel undersurface. It has been found that within these values there is an advantageous and even distribution of forces. Due to the resulting flat arc shape, the coupling elements are advantageously protected against static friction and thus against the risk of breakage.

  • the lower coupling element rests on the surface to be clad during the assembly of the upper coupling element.
  • the forces acting on the lower coupling element can thus be directly and evenly counteracted by the ground and are therefore less damaging to individual components of the lower coupling element.
