Patent number: 6385936Abstract: A floor tile, in particular a laminate panel, parquet element or such like, with an edge profile on at least two opposite edges in the form of a modified groove and tongue joint, is designed in such a way that there is a tongue 20, 30 and a groove 22, 26 on each of the said two edges. The edge profiles are contrived so that the adjacent tiles can be locked in place in relation to each other in both the vertical and horizontal directions. Tongue 20 on the first tile 10 and groove 22 in the second tile 12 rise upwards from the bottom of the tiles at an angle. Accordingly, the bottom wall of groove 26 in the first tile and the bottom outer surface of tongue 30 on the second tile 12 are also inclined at an angle, while the top surfaces of the groove and tongue are oriented horizontally or parallel to the plane of the tile.Type: GrantFiled: October 24, 2000Date of Patent: May 14, 2002Assignee: HW-Industries GmbH & Co., KGInventor: Bernd Schneider

Publication number: 20010039781Abstract: An improved waterproofing system for concrete slab of a flat roof on a building is disclosed. The invention concerns a construction method for installing on the concrete substrate a waterproofing layer comprising hollow plastic panels of designed size, different thickness, and the groove and the tongue joint, and installing a supplementary waterproofing layer using sheet membrane materials such as asphalt sheet, metal sheet and other sheets on the vertical surface, especially the parapet of roof. The invention further concerns a construction method for applying fluid-applied materials after reinforcement with fiber mesh on their joint line to connect plastic panels on substrate with sheet membrane layer on the vertical surface. The waterproofing layer of sloped step type, hollow plastic panels of different thickness permits fast drainage of stagnant water, which inhibits weather damage to the waterproofing layer.Type: ApplicationFiled: April 20, 2001Publication date: November 15, 2001Inventors: Sang Keun Oh, Sung Min Choi, Ki Sun Bae

Patent number: RE39439Abstract: The invention relates to a system for laying and mechanically joining building panels, especially thin, hard, floating floors. Adjacent joint edges (3, 4) of two panels (1, 2) engage each other to provide a first mechanical connection locking the joint edges (3, 4) in a first direction (D1) perpendicular to the principal plane of the panels. In each joint, there is further provided a strip (6) which is integrated with one joint edge (3) and which projects behind the other joint edge (4). The strip (6) has an upwardly protruding locking element (8) engaging in a locking groove (14) in the rear side (16) of the other joint edge (4) to form a second mechanical connection locking the panels (1, 2) in a second direction (D2) parallel to the principal plane of the panels and at right angles to the joint. Both the first and the second mechanical connections allow mutual displacement of joined panels (1, 2) in the direction of the joint.Type: GrantFiled: April 29, 1994Date of Patent: December 26, 2006Assignee: Valinge Aluminium ABInventor: Tony Pervan
