  • Publication number: 20100088993
    Abstract: A floor panel is bounded in a horizontal plane by a top side, which is provided with a decorative layer, and an underside, which is provided for bearing on an underlying surface. The floor panel is provided with connecting structure for the releasable connection of at least two panels. The connecting structure is formed on at least one first side edge such that locking takes place in the transverse direction and vertical direction. A form-fitting element for locking in the vertical direction with a further panel is formed on a second side edge, which runs at an angle to the first side edge. A tongue is formed on the first side edge, the tongue extending in the longitudinal direction of the side edge, and a recess, corresponding to the tongue, is formed on an opposite side edge.

  • Patent number: 7674522
    Abstract: The invention relates to wood fiber insulating material boards and mats, in which the wood fibers and the binder fibers are aligned three-dimensionally. The fleece of wood fibers and binder fibers can alternatively have synthetic resin granules scattered on it. Likewise, a woven fabric or a film can be applied to one or both sides. The product obtained in this way is heated in a heating/cooling oven, calibrated and/or compacted to the desired final thickness.

  • Patent number: 7641963
    Abstract: A panel, in particular floor panel, having a support board made of glued and compressed fiber material to which a termination layer is applied in each case on a top side and an underside, and the termination layer of the top side has a structured surface, and to a process for producing such a panel or such a support board. The object of the invention is to provide a panel or a support board comprising binders and fillers and also a process for producing the same, by means of which surface-structured panels can be produced more quickly and cost-effectively. This object is achieved in that the density on the top side of the support board is lower than the density of the support board on the underside.

  • Publication number: 20090133358
    Abstract: A floor panel including structure for releasably connecting at least two panels. A tongue is formed extending in the longitudinal direction of the side edge and corresponding recess is formed opposite it. The recess comprises a top lip and a bottom lip, and the bottom lip forms a shoulder with a front shoulder side. The shoulder blocks the panels in the transverse direction. An undercut is adjoined by a recess, with a bearing region which corresponds to the shoulder, and a wall, which, with the front shoulder side in the installed state, is located opposite the latter. Form-fitting elements are formed on the wall and the front shoulder side that, in the installed state, engage one inside the other and bring about locking in the vertical direction. An underside of the tongue and a top side of the bottom lip runs parallel to the top side.

  • Patent number: 7506481
    Abstract: A building board made of OSB (oriented strand board) which can be laid on beams, which are spaced apart parallel to one another, in order to form a subfloor in a residential or commercial building and which has two mutually opposite longitudinal edges and two mutually opposite transverse edges running at right angles to the longitudinal edges. One longitudinal edge and one transverse edge in each case has a tongue and the opposite longitudinal edge and transverse edge has a groove corresponding to the tongue, via which a plurality of building boards can be connected to one another and locked in the vertical direction in relation to one another. The tongue and the groove on the longitudinal edge are designed such that two boards which are connected to one another at the longitudinal edges are also locked in a horizontal direction in relation to one another.

  • Publication number: 20070028547
    Abstract: Disclosed is a device for connecting and locking building boards comprising a top face (10) and a bottom face (11), especially floor panels (1, 2) that are provided with a core made of a wood material as well as a groove (3, 4; 5, 6; 18, 19) on two opposite lateral edges (I, II). Said building boards further comprise an insert (7; 8; 9) that is used for locking and can be inserted into the groove (3 or 4; 5, 6; 18, or 19) of one of the lateral edges (I, II). The boards (1, 2) are connected by displacing the boards in an essentially horizontal direction (Q) towards each other. The inventive device is characterized in that the insert (7; 8; 9; 17) is provided with at least one springy lip (7a, 8a; 9a; 17a) which extends towards the top face (10) or the bottom face (11).

  • Patent number: 6862857
    Abstract: A device for connecting and locking structural panels, particularly floor panels, having a groove forming an upper lip and a lower lip over the entire length of at least one lateral border and with a tongue formed on the opposite lateral border corresponding to the groove. To lock panels that have been connected, the tongue is provided with at least one projection and the groove exhibits at least one indentation on the lip that faces the projection, which device is characterized by the indentation being longer than the projection, and on its lateral border (I3, I4) the lip provided with at least one indentation exhibits at least one recess reaching back to the indentation. The length of the recess is at least as great as the length of the projection, and seen in the longitudinal direction, the recess and the projection occupy positions that are staggered, one relative to the other.
