Publication number: 20050034405Abstract: Floorboard and openable locking system therefor comprise an undercut groove on one long side and projecting tongue on an opposite long side of the floorboard. The undercut groove has a corresponding upwardly directed inner locking surface at a distance from its tip. Tongue and undercut groove are formed to be brought together and pulled apart by pivoting motion with a center close to the intersection between the surface planes and common joint plane of two adjoining floorboards. The undercut is produced by at least two disk-shaped cutting tools with rotary shafts inclined relative to each other to form first an inner part of the undercut portion of the groove and then a locking surface positioned closer to the opening of the groove. Installation method for a floor of such boards, manufacturing method for manufacturing the undercut groove and a wedge-shaped tool for laying of the floorboards is also disclosed.Type: ApplicationFiled: September 3, 2004Publication date: February 17, 2005Applicant: VALINGE ALUMINIUM ABInventor: Darko Pervan

Patent number: 6023907Abstract: 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 connection allow mutual displacement of joined panels (1, 2) in the direction of the joint.Type: GrantFiled: November 18, 1998Date of Patent: February 15, 2000Assignee: Valinge Aluminium ABInventor: Tony Pervan
