Abstract: A set of planks (10) for covering a surface (12), comprising a first plank (16) having a first edge (24) defining a connecting tongue (26), and a second plank (18) having a second edge (28) defining a connecting groove (30), the first plank being movable between a disconnected position and a connected position, in which the connecting tongue is snap-fit in the connecting groove, the connecting tongue comprising a distal protrusion (40A) and a proximal protrusion (40B) adapted to abut upwards in the connected position against a proximal lip (42A) and a distal lip (42B) of the connecting groove. The second edge defines a guiding recess (38) at least partly located above the proximal lip (42A) for receiving the distal protrusion in an intermediate position of the first plank, in which the proximal protrusion abuts downwards against the distal lip.

Abstract: A flexible, preferably polymer-based, rectangular floor covering element of double-angling type has six sides: a decorative top face and a bottom face, as well as four edges. The first long edge has a first connection profile with a recess at the bottom face and a tongue overhanging the recess. The second long edge opposite the first long edge has a second connection profile with a protrusion at the bottom face and a groove for receiving the tongue of the first profile. The first short edge is equipped with the first profile and the second short edge is equipped with the second profile. When looking at the floor covering element from above the top face, the edges of the floor covering element are arranged in the following order in the clockwise direction: 1) the first long edge, 2) the first short edge, 3) the second long edge and 4) the second short edge.

Abstract: A floor or wall covering panel has a top and a bottom surface, and at least four sides, where a first and a second side include a first and a second connection profile, respectively, the first profile being configured for mechanically engaging and interlocking with the second profile of another panel, the first profile including a tongue protruding beyond the top edge of the first side, where the second profile includes a groove recessed with respect to the top edge of the second side, the groove is delimited at its bottom by a base, the panel is of laminar structure including a rigid core layer and a wear layer arranged on the core layer, where the core layer includes a first and a second sublayer of a first and a second composite material, respectively, the second sublayer being arranged atop the first sublayer, where both composite materials comprise thermoplastic material and filler material but are of different formulations, and the base delimiting the groove bottom is realized essentially within the fir

Abstract: A set (1) of tiles (5) adapted to cover a surface (10) perpendicular to a thickness direction (V) of the tiles (5), each of the tiles comprising at least one upper layer (24), and an underlying rigid core layer (22), the core layer and the upper layer being superimposed in the thickness direction, and the core layer defining a lower surface (S) opposite the upper layer. The tiles comprise at least one first tile (15) having a first edge extending in a longitudinal direction (L), the core layer of the first tile (15) defining a connecting groove (28) in the first edge.

Abstract: A floor or wall covering panel has a top and a bottom surface, and at least four sides. A first and a second side comprises a first and a second connection profile, respectively. The first profile is configured for mechanically engaging and interlocking with the second profile of another panel. The first profile comprises a tongue protruding beyond the top edge of the first side, whereas the second profile comprises a groove recessed with respect to the top edge of the second side. The groove is delimited at its bottom by a base. The panel is of laminar structure, including a rigid core layer and a wear layer arranged on the core layer. The core layer includes a first and a second sublayer of a first and a second composite material, respectively. The second sublayer is arranged atop the first sublayer. Both composite materials comprise thermoplastic material and filler material but are of different formulations. The base delimiting the groove bottom is realized essentially within the first core sublayer.

Abstract: A decorative surface covering element has a height of 4 mm or less from its top surface to the bottom surface. The surface covering element is configured as a multi-layered compound with a polymer-based core layer laminated between a backing layer and a wear layer, the core layer comprising a core material having a lesser shore hardness than the backing layer and the wear layer. The surface covering element comprises a first connecting profile, integral with the multi-layered compound, that extends along at least one of the edges of the surface covering element. The first connecting profile comprises at least one protrusion realized in the core layer, the protrusion having side surfaces for being seized between opposite surfaces of a recess in a second connecting profile, configured for mating with the first connecting profile, of another decorative surface covering element.
