Wall Or Floor Panel With Locking Means Suitable For Herringbone-Pattern Installation

A wall or floor panel, each having two opposite long edges and two opposite short edges, wherein the panel, at each long edge and at each short edge, has at least one connecting means that allows the panel to be connected to another panel at each other's long edges or at the long edges and the short edges, wherein, at one of the long edges, the connecting means includes a tongue and at least one downward-facing locking groove and one upward-facing locking groove as well as an upward-facing latching hook;

• wherein, at the other long edge, the connecting means has a latching hook and an essentially horizontal locking groove, and wherein, at the short edges, the connecting means includes a tongue and at least one first downward-facing locking groove and one second downward-facing locking groove as well as a latching step, wherein, to connect the connecting means at one of the long edges with the connecting means at one of the other long edges, the downward-facing locking groove and the latching hook are configured such that, in the connected state of the connecting means, the latching hook engages the locking groove in a contact-locking manner between a distal groove surface and a proximal hook surface and the upward-facing latching hook of the connecting element supports itself via a head surface abutting a groove ceiling of the essentially horizontal groove of the connecting element;
• wherein, to connect the connecting means at one of the long edges with the connecting means at the short edges, a tongue of the connecting element is shaped such that, in the connected state of the connecting means, the tongue engages the downward-facing locking groove in a contact-locking manner between a proximal groove wall and a distal tongue surface, in a contact-locking manner between a proximal hook surface and a proximal tongue surface, and in a contact-locking manner between a basal projection surface of a projection of the connecting element and an apical tongue surface of the tongue of the connecting element;
• and wherein, to connect the connecting means at one of the long edges with the connecting means at the short edges, the tongue of the connecting element is shaped such that, in the connected state of the connecting means, the apical tongue surface of the tongue is contact-locked to a basal projection surface of a proximal projection of the connecting element, a groove wall surface of the downward-facing locking groove is contact-locked to the proximal hook surface of the latching hook of the connecting element, and a base surface of a tongue base of the connecting element is contact-locked to an apical hook arm surface of the latching hook.
