Patent number: 7587865Abstract: The principles described herein provide floor tiles and modular floors. Some embodiments of the floor tiles and modular floors include multiple levels of support. One of the levels of support may be a resilient level that compresses comfortably under a load. Another level of support may include a generally rigid level that supports the floor or tile after the resilient level has compressed a predetermined distance. One embodiment includes a third generally rigid level of support that supports the floor or tile under certain loads. Some embodiments of the floor tiles include inserts for increased traction. The inserts may be removable and protrude from a top surface and/or a bottom plane of the floor tiles.

Patent number: 7255897Abstract: The invention relates to the use of aqueous, isocyanate-free, polyurethane dispersions with a solid content of ?30 wt. % and a solvent content of ?10 wt. % in sports floor coverings. The inventive polyurethane dispersions are particularly suitable for use as bonding agents for elastic coatings, spray coatings or flow coatings on elastic or rigid undersurfaces, adhesion promoters or primary coatings, fillers for sealing pores, adhesives for gluing pre-fabricated plastic coatings or for sealing sports floor coverings. The inventive polyurethane dispersions are environmentally friendly and easy to manufacture. They are also partly characterized by improved product features, e.g. mechanical properties, UV resistance and color stability, with respect to the corresponding sports floor coverings.Type: GrantFiled: January 25, 2001Date of Patent: August 14, 2007Assignee: Construction Research & Technology GmbHInventors: Werner Temme, Ralph Bergs, Hans Haberle, Alois Maier

Patent number: 7225591Abstract: A two-ply flooring plank is disclosed having two layers or “plies” with a bottom layer having a grain that runs generally transverse to a top layer or “cross-ply” to provide dimensional stability to the plank. The bottom layer includes a number of strips secured to the bottom of the top layer. The bottom layer strips are also placed with gaps between the individual strips of the second layer to allow flexibility of the flooring plank, which allows the flooring to more easily conform to irregularities in a subfloor upon which the flooring plank is mounted.Type: GrantFiled: April 5, 2004Date of Patent: June 5, 2007Assignee: Hangzhou Dazhuang Floor Co., Ltd.Inventors: Hai Lin, Xufeng Xu

Patent number: 7185466Abstract: A sub-floor assembly having sub-floor panels that are adapted to be integrally overlapped while providing clearance for channel sections when the floor deflects under load. Clearance for the channel sections may be achieved by providing pockets in an upper layer of a first sub-floor panel in the area where the channel sections engage a second sub-floor panel with which the first sub-floor panel is in overlapping engagement.Type: GrantFiled: May 20, 2004Date of Patent: March 6, 2007Assignee: Connor Sports Flooring CorporationInventor: Erlin Randjelovic

Patent number: 7147907Abstract: Apparatus and methods for preventing splinters and minimizing the number of injuries attributable to falling onto pressure-treated wooden members, such as landscape ties or timbers used in play areas and landscape projects, through the use of a resilient cover. A cover and various embodiments include a moldable or extrudable waterproof material in the form of a channel having a top wall and two opposing side walls. The combination of channel thickness and composition provides an impact resistance suitable to prevent injuries when one falls upon it. The inner dimensions of the channel are such that the channel fits tightly over the top and sides of a construction beam or timber.Type: GrantFiled: June 30, 2003Date of Patent: December 12, 2006Inventor: Robert L. Hiltz

Patent number: 7127857Abstract: A floor support assembly including first and second subfloors is disclosed. The first subfloor is supported over a substrate by a plurality of pads. Each pad is housed in a corresponding recess formed in the first subfloor. Each recess includes a ridge that is in contact only with its respective pad when the floor is in a lightly loaded position. In a more aggressively athletically loaded state, the pad contacts the ridge and a portion of the top of the recess. In a non-athletic fully loaded state, the first subfloor plate near the load rests on the substrate. The second subfloor is located above the first subfloor and is supported by the first subfloor. A method of installing the same is also disclosed.Type: GrantFiled: September 4, 2002Date of Patent: October 31, 2006Assignee: Connor Sports Flooring CorporationInventor: Erlin A. Randjelovic

Patent number: 7121059Abstract: The invention relates to a system for laying and mechanically joining building panels, especially thin, hard, floating floors. Adjacent joint edges of two panels engage each other to provide a first mechanical connection locking the joint edges in a first direction perpendicular to the principal plane of the panels. In each joint, there is further provided a strip which is integrated with one joint edge and which projects behind the other joint edge. The strip has an upwardly protruding locking element engaging in a locking groove in the rear side of the other joint edge to form a second mechanical connection locking the panels in a second direction 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 in the direction of the joint.Type: GrantFiled: May 7, 2003Date of Patent: October 17, 2006Assignee: Valinge Innovation ABInventor: Tony Pervan

Patent number: 7121052Abstract: A panel-type subfloor assembly for an anchored/resilient floor includes a plurality of elongated panels laid end-to-end in parallel rows along a first direction, the panels having elongated slots formed therein that are oriented at an oblique angle relative to the first direction. For the entire floor, this results in a plurality of aligned rows of elongated slots oriented at an oblique angle relative to the first direction. Each slot cooperates with an elongated fastener, namely an elongated dual flanged channel held by at least one pin. The fastener is positioned within the respective slot and adapted to hold the respective panel to the base along two longitudinal edges of the slots, in a manner that limits upward movement of the panel while permitting downward deflection.Type: GrantFiled: April 25, 2005Date of Patent: October 17, 2006Assignee: Robbins, Inc.Inventors: Michael W. Niese, Paul W. Elliot, John Richard Puening

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
