    Abstract: A panel with a working surface and four edges of which oppositely disposed pairs of edges have corresponding holding profiles so similar panels are connectable. Holding profiles of a first pair of edges are connectable by angular movement into interlocking relationship Holding profiles of a second pair of edges are hook elements, which are connectable to similar adjacent panels by joining movement provided a hook element is a separate vertical locking element projecting toward joining movement of the hook elements. During joining, the vertical locking element is movable out of the path of joining movement and when hooked, the hook elements are movable toward the joining movement by spring action. When dismantling, connected panels are unlockable from hooked and vertically locked condition by pivoting about an axis near the hooked edges and toward an unlocking position. The working surfaces, when unlocked, are less than 180° relative to each other.

  • Patent number: 7841150
    Abstract: Floorboards (1, 1?) are shown, which are provided with a mechanical locking system consisting of a separately machined locking strip (6) which is mechanically joined with the floorboard (1), the locking strip (6) being designed for mechanical fixing to the floorboard (1) by means of a joint, which is operable by snapping-in and/or inward angling, and the locking strip (6) being designed to connect the floorboard (1) with the essentially identical floorboard (1?) by at least inward angling. Moreover, a locking strip, a strip blank, a set of parts for making a floorboard and methods for manufacturing a floorboard and a locking strip, respectively, are shown.

  • Patent number: 7823359
    Abstract: Floorboards with substantially planar and parallel upper top sides and lower undersides and panel material located between the upper and lower top sides, and a mechanical locking system for locking a first edge of a first floor board to a second edge of a substantially identical second floor board, the mechanical locking system including a tongue and groove forming a first mechanical connection locking the first and second edges to each other in a first direction at right angles to a principal plane of the floor boards, and a locking device forming a second mechanical connection locking the first and the second edges to each other in a second direction and at right angles to the edges; wherein, when the first edge and the second edge are locked together, there is space in the locking system between the first and the second edges.

  • Patent number: 7779596
    Abstract: 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.

  • Patent number: 7762036
    Abstract: Natural wood sandwiched engineered flooring utilizes all natural wood as the raw material which is made into several components which are combined to make this product. The components are a single or multilayer top veneer bottom or base layer and a middle layer. The four sides of the natural wood sandwiched engineered flooring strip consist of either a tongue and a groove or an interlocking system. The middle layer consists of two parallel solid wood strips, and located perpendicular to and between the parallel solid wood strips are small pieces of soft wood, which are glued together. The small soft wood pieces can be of fast growing soft wood, and as such saves treasured hardwood lumber. The production cost of the raw material is much lower than other types of engineered flooring. Further, an enhanced stabilization of the hardwood flooring is provided which is more suitable for radiant heat.

  • Patent number: 7762035
    Abstract: Floor panel in a board shape having at least at two opposite edges coupling parts enabling several of the panels to be coupled to each other, wherein the coupling parts have contact portions forcing the floor panels in the coupled condition with a tension force at least laterally towards each other. The coupling parts also include support portions, which, in the coupled condition of floor panels, create a fixation in the mutual position of the contact portions cooperating under tension.
