Panel, especially floor panel
View Patent ↗A panel, in particular floor panel, with a core of wood material or a wood material/plastic mixture, a top side and a bottom side, which panel has on at least two opposite lateral edges a profiling corresponding to one another such that two identically embodied panels can be connected and locked to one another by an essentially vertical joining motion in the horizontal and vertical directions, wherein the locking in the vertical direction can be brought about by at least one tongue element movable in the horizontal direction, which element snaps into place during the joining motion behind a locking edge extending essentially in the horizontal direction, is characterized in that the tongue element is formed in one piece out of the core.
1. A method for producing a floor panel, with a core of wood material or a wood material/plastic mixture, a top and a bottom, which has on at least two side edges (I, II) lying opposite one another a profile corresponding to one another such that two panels embodied identically can be connected and locked to one another in a horizontal and vertical direction by an essentially vertical joining movement, wherein the locking in the vertical direction can be effected by at least one tongue element formed in one piece from the core on the side edge (II) and moveable in the horizontal direction, which tongue element during the joining movement snaps in behind a locking edge extending essentially in the horizontal direction, in that, by means of tools displaceable transversely to a processing direction, the at least one tongue element is exposed with respect to the core in the direction of the top and in the direction of the side edge (I) lying opposite the top, and thereby remains connected to the core in the direction of its side edge (II) on at least one of its two ends.
2. The method according to claim 1 , wherein milling tools, laser tools or water-jet tools, upright blades or broaches are used as the tools.
3. The method according to claim 2 , wherein the tongue element remains connected at both of its ends to the core.
4. The method according to claim 1 , wherein the tongue element remains connected at both of its ends to the core.
5. The method according to claim 1 wherein the tongue element is exposed with respect to the core by means of an essentially horizontal slot and an essentially vertical slot.
6. The method according to claim 1 , wherein a plurality of tongue elements spaced apart from one another are exposed over a length of the side edge (II).
7. The method according to claim 1 , wherein the outer edge of the tongue element is bevelled at an angle (α) to the top.
