Definitions

  • the invention relates to a panel, comprising a panel top and a panel bottom and at least four panel edges, which face each other in pairs, with matching at the panel edges complementary retaining profiles that match such that similar panels are fastened together, wherein at least one of the retaining profile pairs provided with hook profiles is, namely on a panel edge with a receiving hook and on the opposite panel edge with a locking hook.
  • floor coverings are made, in particular, such panels are suitable for floating floor coverings.
  • the panels usually have decorative surfaces.
  • the proposed panel should be suitable for interlocking according to the "fold-down method".
  • a Paneelart is used in which one of the retaining profile pairs is provided with a modified tongue and groove profile, while the other pair of retaining profile is provided with the hook profiles according to the invention.
  • a new panel is angled and preferably brought with its spring profile edge to the groove profile edge of a horizontal panel or a row of panels. Subsequently, the new panel is pivoted down into the plane of the assembled panels and thereby locks the spring profile form-fitting with the groove profile.
  • a positive locking of the hook profiles is generated at the same time, because one of the hook profiles scissor-like moved to the other hook profile and positively interlocked with this hook. There is a lock instead.
  • the proposed hook profiles are also suitable for a push-down locking.
  • all the panel pairs of panels need to be connected by a vertical movement, i. for example, by a lowering movement of a panel, namely in a direction perpendicular to the panel top direction (vertical).
  • the fold-down method is then not applicable.
  • a panel can not be locked at the end of a panel row because a wall in the way and the panel is too long.
  • a panel e.g. cut with a saw to cut it to the required length.
  • a new row of panels can be started with the separated residual piece of the panel.
  • the complementary retaining profiles of a severed panel always fit together. In principle, therefore, complementary retaining profile edges of a severed panel can be locked together.
  • the WO 01/02670 proposes different hook profile pairs.
  • the hook profiles are intended to prevent horizontal pulling apart of the panels, ie in the panel plane and perpendicular to the locked panel edges. However, it appears in a load in said horizontal direction that the strength of the hook profiles is unsatisfactory.
