The contoured first header couples to the contoured second header of another plurality of masonry articles and the contoured lower base couples to the upper base of the other plurality of masonry articles so that an outward face of a portion of a wall assembled with the plurality of masonry articles has a mortar-like vertically oriented gap and a mortar-like horizontally oriented gap. A plurality of corner masonry article and plurality of alternative corner masonry articles similar to the plurality of masonry articles permit assembly of a portion of a corner section of the wall.Type: GrantFiled: November 24, 2003Date of Patent: November 8, 2005Inventor: Aldo Banova

Patent number: 6922964Abstract: A floorboard system includes a plurality of floorboards, wherein each of the floorboards is a rectangular floorboard provided with long edges and short edges and having a floorboard body provided with an integrated long edge locking system and an integrated short edge locking system for mechanical joining, both vertically and horizontally, the floorboards, along the long edges thereof and along the short edges thereof. The long edge locking system differs from the short edge locking system in respect of at least one of material composition and material properties. And, at least one of the long edge locking system and the short edge locking system includes a separate element which is integrally connected with the floorboard body at the factory and is made of a material other than that included in the floorboard body.Type: GrantFiled: February 11, 2003Date of Patent: August 2, 2005Assignee: Valinge Aluminium ABInventor: Darko Pervan

Patent number: 6918220Abstract: The invention relates to a locking system for mechanical joining of floorboards (1, 1?), a floorboard having such a locking system and a flooring made of such floorboards. The locking system has mechanical cooperating means (36, 38; 6, 8, 14) for vertical and horizontal joining of adjoining floorboards. The means for horizontal joining about a vertical plane (F) comprise a locking groove (14) and a locking strip (16) which is located at opposite joint edge portions (4a, 4b) of the floorboard (4). The locking strip (6) projects from the joint plane (F) and has an upwards projecting locking element (8) at its free end. The locking groove (14) is formed in the opposite joint edge portion (4a) of the floorboard at a distance from the joint plane (F). The locking groove (14) and the locking element (8) have operative locking surfaces (10, 11).Type: GrantFiled: February 7, 2003Date of Patent: July 19, 2005Assignee: Valinge Aluminium ABInventor: Darko Pervan

Patent number: 6898913Abstract: The invention relates to a locking system for mechanical joining of floorboards (1, 1?) which have a body (30), a lower balancing layer (34) and an upper surface layer (32). A strip (6) is integrally formed with the body (30) of the floorboard (1) and extends under an adjoining floorboard (1?). The strip (6) has a locking element (8), which engages a looking groove (14) in the underside of the adjoining floorboard (1?) and forms a horizontal joint. A tongue (38) and a tongue groove (36) form a vertical joint between upper and lower plane-parallel contact surfaces (43, 45) and are designed in such manner that the lower contact surfaces (45) are on a level between the upper side of the locking element (8) and a plane containing the underside (3) of the floorboard. The invention also relates to a floorboard having such a locking system, a floor made of such floorboards, as well as a method for making such a locking system.Type: GrantFiled: September 27, 2002Date of Patent: May 31, 2005Assignee: Valinge Aluminium ABInventor: Darko Pervan

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
