Patent number: 7810299Abstract: A floor tile for a raised floor. The floor tile is defined by a shallow upwardly-opening metal pan defining a shallow compartment in which a main preformed one-piece concrete block is secured. The main concrete block is preferably formed from a plurality of one-piece preformed concrete sub-blocks which are adhesively adhered in sideward abutting relationship to define a plan profile corresponding to the main concrete block. The main concrete block is then adhesively secured within the compartment of the metal pan.Type: GrantFiled: December 3, 2007Date of Patent: October 12, 2010Assignee: Haworth, Inc.Inventors: Ronald H. Brown, Bryan R. Gingrich, Anthony McConnell, Robert L. Tuttle, Randolph Woellper, X. Shawn Yu

Patent number: 7055287Abstract: This invention relates to a space-dividing wall panel system having a plurality of base panels which are serially connectable one with the other to define a vertically enlarged wall supported on a floor. Each base panel is defined by at least one horizontal box-beam rigidly connected to a pair of laterally spaced apart vertical uprights which are connected at the opposite ends of the box-beam and have a reduced thickness compared thereto. With this clearance between the faces of the box-beam and the uprights, the box-beam, cross rails at the ends of the uprights as well as additional extension panels are formed with longitudinally extending channels which are positioned free of interference with the vertical uprights and aligned with serially-adjacent channels of serially-adjacent wall panels.Type: GrantFiled: December 8, 2003Date of Patent: June 6, 2006Assignee: Haworth, Inc.Inventors: X. Shawn Yu, Bryan R. Gingrich, Robert L. Tuttle, Keith Foco

Patent number: 6920727Abstract: A space-dividing wall panel arrangement having a plurality of upright wall panels serially connected one with the other by an upright support post. The wall panel arrangement additionally includes an open-frame structure which allows routing of cabling therethrough to provide power and communication capabilities to a workstation defined by the wall panels, and a removable and rigid top cap which is capable of supporting various furniture-type accessories at selected locations along the longitudinal extent of the panel arrangement, and which also permits mounting of return wall panels to permit greater flexibility in configuring a workstation.Type: GrantFiled: February 14, 2001Date of Patent: July 26, 2005Assignee: Haworth, Inc.Inventors: X. Shawn Yu, Steven A. Heyer
