A floor assembly includes a plurality of boards and bases. Each board is provided on the bottom surface thereof with a sliding groove. Each base includes a main body, a positioning member, and first and second buckling members. The positioning member is slidably disposed in the sliding groove of the board. The first buckling member is located at the left side of the main body and has a buckling block and a notch. The second buckling member is located at the right side of the main body and has an accommodating space and a protrusion. The adjacent bases are connected with each other in a way that the buckling block is disposed in the accommodating space and the protrusion is embedded in the notch. As a result, the floor assembly is simplified in structure and assembling process, thereby convenient in construction and stable in structure.

Floor panels 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 that during locking bends upwardly or downwardly. The locking system includes a first and a second joint edge section with different locking functions. One section provides a horizontal locking and another section provides a vertical locking.

A mounting clip (1) for the floating mounting of wall and ceiling panels consisting of composite wood materials, said panels being connected to one another without adhesive by corresponding locking profiles to form a wall or ceiling covering and being fastened to a substructure. The mounting clip has a base board (2), a receiving portion (4) formed in one piece with the base board and intended for engaging in a locking profile of a panel, wherein the receiving portion has a distancing piece (5) arranged as far as possible perpendicularly to the plane of the base board, and a contacting piece (6), which adjoins the distancing piece and is arranged as far as possible parallel to the plane of the base board, and a slot (8) is provided in the base board for fastening the mounting clip to a fastening means on the substructure the slot can be at least 1.5-4 cm long and extend transversely with respect to the contacting piece.

Building panels, such as a floor panels or wall panels. The panels include a first mechanical locking system at respective parallel and opposite third and fourth edges, such as long edges, configured to cooperate for horizontal and vertical locking between two adjacent building panels, preferably by means of a folding motion. The panels further include a second locking system at respective parallel and opposite first and second edges, such as short edges, configured to cooperate for horizontal and vertical locking of two adjacent building panels. An upper edge portion of one of the third edge or fourth edge, preferably the third edge, includes a first lower lip portion configured to cooperate with a first upper lip portion of an upper edge portion of the other of the third and fourth edge of an adjacent panel when the third and fourth edges are arranged in locking engagement.

A panel element may be provided for a covering. In particular, a panel element for a floor, wall or ceiling covering, which covering may be formed by a plurality of panel elements of the same kind which are connected to one another. Each panel element has a basic body having a defined total thickness and upper and a lower surfaces. The basic body has in each case differently contoured longitudinal sides and in each case differently contoured end faces. One longitudinal side has groove-like contouring and the other longitudinal side has tongue-like contouring corresponding thereto.

A panel comprising a centrally located core, at least one first coupling part and at least one second coupling part connected respectively to opposite edges of the core, which first coupling part includes an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove formed in between the upward tongue and the upward flank wherein the upward groove is adapted to receive at least a part of a downward tongue of a second coupling part of an adjacent panel: which second coupling part includes a downward tongue, at least one downward flank lying at a distance from the downward tongue, and a downward groove formed in between the downward tongue and the downward flank, wherein the downward groove is adapted to receive at least a part of an upward tongue of a first coupling part of an adjacent panel.

Provided is a hard floor panel having a top side and a bottom side and having side edges along the panel sides for floating installation to form a floor panel composite. At least two floor panels are joined together in each case, the opposite side edges being provided with tongue-and-groove profiles, a tongue and a joining surface is provided in a first side edge and a groove and a joining surface is provided in a second opposite side edge. The tongue of the first side edge has an upper side and a lower side. A projection with a contact surface is provided on the lower side of the tongue. The joining surface of the first side edge extends from the upper side of the floor panel towards the upper tongue side and the joining surface is beveled.

Method for manufacturing a plastic panel having a first side (1) with a hook (11), a first assembly cavity (12) and a locking cavity (13) which is recessed and whose upper side forms a bearing surface and a protrusion (21) comprising a beak (24) in the junction plane, an inset recess (23) continuing by a bearing point (32) connecting with a groove (31), a flexible lock (3) which can retract by elastic deformation into the recess (23) during the assembly movement of the panel (100a) to be installed and extend inside the locking cavity (13). According to the method, the first side (1) is machined (I) to its final section and with the blank of the second side (2) with a protruding tab (4) which is locally heated (II) after cooling (III) to bend it and form the lock (3).

Surface coverings, such as floor coverings, with an interlocking design are described. Methods of making the surface coverings are further described. A plank including a resilient composite sheet having four sides, an upper surface, a lower surface, and an overall thickness, and said composite sheet comprising at least one base layer, wherein said at least one base layer comprising at least one polymeric material and at least one filler, wherein opposite sides of the composite sheet comprise a first tongue on a first side and a first groove on the opposite second side, wherein the first tongue and first groove have complementary shape to each other to be interlockingly engageable with a corresponding groove or tongue on an adjacent floor plank.

A panel having a panel surface and an edge pair of mutually opposite complementary panel edges provided with complementary locking elements. The complementary locking elements are configured such that, when two panels are assembled, both a locking action of the panel edges in a direction perpendicular to the panel surface and a locking action preventing the panels from moving apart is achieved underneath a visible joint by the assembled complementary locking elements. The panel edges with the locking elements have an upper portion and a lower portion, relative to thickness of the panel. The locking elements are arranged and configured in the lower portion. The upper portion forms the upper joint region, including the visible part of the joint. The upper portion on each panel edge of the edge pair has a chamfer which, when two panels are assembled, forms a depressed joint. The chamfers of the complementary panel edges are different sizes in the upper portion. When two complementary panel edges are assembled, the larger chamfer is covered by the smaller chamfer. A butt-joint abutment surface is provided on a lower end of the larger chamfer.
