  • Fluid resistance refers to the ability of a panel assembly to resist the passage of fluids, such as water, from the top of the panels and between adjacent panels to the underside of the panels, and ideally to prevent this passage entirely.
  • fluids such as water
  • FR 2 922 568 A1 discloses that in cross-section the tongue of a first panel on its underside and the lower lip of the groove of an adjacent second panel, identical to the first, each have on their upper side two projections projecting downwards and two recesses complementary to each other which engage when one panel is rotated with respect to another to form a double means for engaging the tongue in the groove.
  • DE 10 2006 057 491 A1 discloses a panel with a usable surface and with four edges, of which opposite edge pairs have corresponding holding profiles, so that similar panels can be connected at all four edges, wherein the holding profiles of a first pair of edges can be connected by angling, and wherein the holding profiles of a second pair of edges are designed as complementary hook elements, so that a similar adjacent panel can be connected to each of the hook elements essentially by means of a joining movement which takes place in a plane of movement perpendicular to the plane of the panel, with the proviso that at least one of the hook elements of the second pair of edges is provided with a separate vertical locking element which projects at least partially into the joining path of the hook elements, wherein the vertical locking element can be automatically moved out of the joining path during the joining movement of the hook elements of two panels in order to release it, and can be automatically moved back into the joining path by spring action when the hook elements are hooked.

  • the surface of the locking receptacle and the surface of the locking element each have a wave structure, wherein these wave structures are complementary to one another.
  • the fact that the wave structures are complementary to one another means that the shape of these wave-shaped surfaces is such that, when two panels are coupled, they lie flat against one another. This is achieved by the surface shapes of the locking receptacle and the locking element corresponding to one another. Where the locking receptacle has a wave trough, the locking element is provided with a wave crest, and vice versa. In this way, an interlocking of the two surfaces is essentially achieved.
  • the interface between the locking receptacle and the locking element is larger than with flat surfaces, which ultimately further complicates the passage of fluid between the locking receptacle and the locking element. In this way, an even higher fluid resistance of a panel assembly consisting of such panels can be achieved.
  • wave structures in the locking receptacle and the locking element run perpendicular to the panel side surfaces having the mutually complementary coupling elements. It has been shown that particularly good fluid resistance can be achieved in this way. Furthermore, the shape of the wave structures can follow various forms. According to a preferred However, a further development of the invention provides that the wave structures in the locking receptacle and the locking element are sinusoidal.
  • the number of wave crests and troughs can vary in principle.
  • the wave structures have at least four wave crests, preferably at least five wave crests, and most 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.
  • 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 determined by the distance between the panel surface and the panel underside.
  • the invention allows the surfaces of the locking element and the surface of the locking receptacle as a whole, i.e., without taking the wave structure into account, to both be essentially flat.
  • the surfaces of the locking element are generally convex perpendicular to the panel side surfaces having the complementary coupling elements
  • the surface of the locking receptacle is generally concave perpendicular to the panel side surfaces having the complementary coupling elements.
  • surfaces are generally convex or concave, this refers to the shape of the surfaces without the wave structures.
  • the wave structures of course, mean that both surfaces repeatedly have convex or concave areas locally.
  • the surfaces of the locking element according to the preferred development of the invention described here are 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 is adapted to the surface of the locking element.
  • the surfaces of the locking element and the surface of the locking receptacle are perpendicular
  • the radius of the surface of the locking element and the surface of the locking receptacle are in the range of 85% to 95% of the total thickness of the panel, determined by the distance between the panel surface and the panel base. It has been found that within these values, a favorable and even distribution of forces occurs.
  • the resulting flat arched shape advantageously protects the coupling elements from static friction and thus from the risk of breakage.
  • a tangent to the center of the circular segment shape of the surface of the locking element and/or a tangent to the center of the circular segment shape of the surface of the locking receptacle encloses a respective arc angle ⁇ of a maximum of 45°, preferably a maximum of 35°, particularly preferably a maximum of 25°, with respect to the panel surface and the panel undersurface.

  • the material thickness of the lower coupling element between the panel's underside and the locking receptacle is less than the material thickness of the upper coupling element between the panel's surface and the locking receptacle.
  • the assembly loads on the lower coupling element can generally be better balanced than the assembly loads on the upper coupling element. This is due, among other things, to the fact that the lower coupling element rests on the surface to be clad during assembly of the upper coupling element. The forces acting on the lower coupling element can therefore be directly and evenly supported by the substrate and are therefore less damaging to individual components of the lower coupling element. In contrast, forces acting on the upper coupling element during the joining of two panels have no such opportunity for force distribution, so that the upper coupling element is generally more prone to material failure. Such material failure or fracture usually occurs in areas with high loads and the smallest possible material thickness.
