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