  • the panel according to the invention comprises at a first pair of opposing edges a first set of complementary coupling profiles and at a second pair of opposing edges a distinctive second set of complementary coupling profiles.
  • the first and second edges facilitate an easy installation of a panel by inserting the sideward tongue of the first edge of the panel to be coupled in an inclined position into the recess of the second edge of an already installed panel, after which that panel will be angled (pivoted) downwardly until both panels are situated in the same plane.

  • a locking in vertical direction at the first and second edges of two panels is established by the engagement of a top surface of the sideward tongue to a bottom surface of the upper lip acting as locking surface. In fact, the upper lip prevents the inserted sideward tongue to be displaced in vertical direction.
  • a locking in horizontal direction between two panels is established by the presence of the upward tongue at the third edge which engages to the downward tongue at the fourth edge (of another panel), which prevents the two panels to be drifted apart.
  • a locking in vertical direction between two panels is established by the application of the closed grooves as indicated above, and moreover, due to the presence of the additional first and second locking elements.

  • a bottom surface of the front region of the sideward tongue is at least partly rounded, which facilitates angling down of the panel, wherein a more or less central part of the front region of the sideward tongue will act as pivoting axis. Since the sideward tongue is inserted into the recess during angling down, the pivoting axis will be displaced slightly during the angling down process.
  • the shape of a bottom surface of the lower lip defining the recess, configured for supporting the front region of the sideward tongue is preferably
  • the bottom surface of the recess is preferably also at least partly rounded.

  • At least a part of a side of the downward tongue facing away from the downward flank forms a downward aligning edge for the purpose of coupling the fourth edge to a third edge of an adjacent panel.
  • this aligning edge which may also be flat and/or rounded, also serves to facilitate a correct mutual positioning of the fourth and third edges, and therefore the ease of mutual coupling of both edges.
  • each of the upward tongue and the downward tongue is preferably substantially rigid, which means that the tongues are not configured to be subjected to deformation.
  • the tongues as such are relatively stiff and hence non-flexible.
  • the tongues are preferably substantially solid, which means that the tongues are substantially massive and thus completely filled with material and are therefore not provided with grooves at an upper surface which would weaken the construction of the tongue and hence of the floor panel connection to be realised.
  • a rigid, solid tongue By applying a rigid, solid tongue a relatively firm and durable tongue is obtained by means of which a reliable and the durable floor panel connection can be realised without using separate, additional components to realise a durable connection.
  • the upward tongue and the downward tongue are each connected to the core by means of a bridge.

  • the upper side of the floor panel is adapted to engage substantially seamless to the upper side of another floor panel, as a result of which a seamless connection between two floor panels, and in particular the upper surfaces thereof, can be realised.
  • the first locking element is positioned at a distance from an upper side of the upward tongue. This is favourable, since this will commonly result in the situation that the first locking element is positioned at a lower level than the upward aligning edge of the floor panel, which has the advantage that the maximum deformation of the fourth edge can be reduced, whereas the connection process and deformation process can be executed in successive steps.
  • the second locking element is complementary positioned at a distance from an upper side of the downward groove.
  • the first locking element is positioned at a distance from a lower side of the upward tongue, which may also facilitate coupling. The positioning of the complementary second locking element will be such that both locking element will co-act in the coupled state of the third and fourth edge.
  • the effective height of the downward aligned edge is larger than the effective height of the upward tongue. This commonly results in the situation that the downward aligning edge of a floor panel does not engage another floor panel in case of a pre- aligned state (intermediate state).
  • the position- selective contactless pre-alignment does prevent or counteract forcing the downward aligning edge of a floor panel along the upper surface of another floor panel, which could damage the floor panels.

  • the eventual inclination of the tongue side facing toward the flank usually also depends on the production means applied to manufacture the floor panel.
  • inclination of the downward aligned edge is less than the inclination of at least an upper part of the upward flank, as result of which an expansion chamber will be formed between both surface which will be favourable to allow play and to compensate expansion, e.g. due to moist absorption by the floor panels.
  • an upper side of the upward tongue extends in a direction toward the normal of the upper side of the core. This has the result that the thickness of the upward tongue decreases in the direction of the side of the tongue facing away from the upward flank.
  • an upper side of the upward tongue runs inclining downward in the direction of the side of the upward tongue facing away from upward flank, and wherein an upper side of the downward groove having a likewise inclining orientation upward in the direction of the side of the downward tongue facing towards to downward flank.
