A mat unit is formed from at least two layers ultrasonically welded together. Each layer is individually formed from non-vinyl nontoxic thermoplastic elastomer (TPE) material. In ultrasonically joining the two layers together, there is no need to use additional materials, such as adhesive (i.e., chemical attachment) or stitched thread (i.e., mechanical attachment) to form the joint/weld point. Once formed from the two layers, the mat unit has four quadrants and a plurality of longitudinal ribs integrally formed in the first layer positioned in the first and third quadrants, and a plurality of transverse ribs integrally formed in the first layer positioned in the second and fourth quadrants. Additionally, there are a plurality of longitudinal ribs integrally formed in the second layer positioned in the second and fourth quadrants, and a plurality of transverse ribs integrally formed in the second layer positioned in the first and third quadrants.

A floor panel includes a substrate and a top layer provided on the substrate. The top layer is composed of a print and a transparent thermoplastic layer having a thickness of 0.5 mm or less and being situated above said print. The floor panel, at least on two opposite edges, is provided with a straight or curved chamfer extending to below the global level of the print.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically.

Floor panels (1, 1′) are shown, which are provided with a mechanical locking system that may be locked with a vertical displacement of a first panel against a second panel. The locking system includes a flexible strip (6) that during locking bends upwardly or downwardly. The locking system includes a first (7a) and a second (7b) joint edge section with different locking functions. One section provides a horizontal locking and another section provides a vertical locking.

The invention relates to a modular metal covering for buildings, consisting of successive metal sheets (1) which are interconnected by means of joining corresponding bends in the edges thereof, said connections being supported and fastened on supports (2), a lower groove (6) determining the bending of the edges of the metal sheets (1), wherefrom a vertical section extends, ending in a downward-oriented upper break, wherefrom one of the bends extends upwards, successively determining a bowed wing (9), a horizontal section (10) and a vertical section (11), while the other bend extends from the upper break with a wing (12) defining a domed shape; each support (2) comprising a body in the form of a column which determines structures to which said bends of the metal plates (1) are fitted.

A set of building panels, each building panel has a decorative surface and a mechanical locking device for horizontal and vertical locking of similar or essentially identical building panels in an assembled position. An upper edge portion of a side edge of a first building panel and an upper edge portion of a side edge of a second building panel are, in the assembled position, juxtaposed to form a joint seal. The mechanical locking device includes a locking surface at the upper edge portion of the side edge of the first building panel configured to cooperate with a locking surface at the upper edge portion of the side edge of the second building panel. The two locking surfaces are configured to lock the side edge of the first building panel and the side edge of the second building panel in a direction parallel to the extension of the decorative surface.

Floor panel, with a horizontally and vertically active locking system allowing that two of such floor panels can be connected to each other at said sides by providing one of these floor panels, by means of a downward movement, in the other floor panel; wherein the vertically active locking system comprises a locking element in the form of an insert; wherein this locking element comprises at least a pivotable lock-up body; characterized in that the pivotable lock-up body comprises a support portion which is rotatable against a support surface pertaining to the floor panel concerned, and more particularly in a seat.

The invention relates to a floor panel, in particular a laminated floor panel. The invention also relates to a floor covering consisting of a plurality of mutually coupled floor panels according to the invention. The invention further relates to a method for mutually coupling two floor panels, in particular laminated floor panels, according to the invention.

A floor panel is of synthetic material and forms a layer-shaped substrate with first and second pairs of opposite edges. The first pair of opposite edges has coupling parts forming a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, and forms a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels. The coupling parts on the first pair of opposite edges are realized substantially in the material of the floor panel itself. The floor panel is provided with an edge configuration on the second pair of edges allowing two of such floor panels to be positioned with their respective edge alongside each other and free from mechanical horizontally active locking systems.

A floor panel for forming a floor covering includes a pair of edges provided with coupling parts allowing to couple two of such floor panels to each other by means of a rotation movement. The coupling parts are realized in the form of a tongue and a groove with locking parts. The groove is bordered by an upper lip and a lower lip which comprises a locking part in the form of an upward-directed locking part. The upward-directed part extends over a height which is more than 0.1 times the thickness of the floor panel.
