  • Publication number: 20230042342
    Abstract: A set of floor panels includes a first floor panel having a first holding profile at a lateral edge, a second floor panel having a second holding profile at a lateral edge joinable to the first holding profile by a substantially vertically oriented downward movement of the second floor panel, and a separate L-shaped clip including a horizontal leg, a vertical leg and a detent tab adjoining an upper end of the vertical leg, the clip inserted into a clip groove of the first holding profile, the detent tab attaining a locking position for vertically locking the holding profiles during or after the downward movement of the second floor panel, such that when the clip is inserted into the clip groove, the horizontal leg generates a tensioning force by which the upper end of the vertical leg is pushed against an upper delimiting wall of the clip groove.

  • Patent number: 8038363
    Abstract: A panel fastening system, especially floor panels, whose narrow sides are fitted with retaining profiles. The retaining profile of a front narrow side, the retaining profile of the opposite back narrow side, the retaining profile of a left narrow side and the retaining profile of the opposite right narrow side of a panel match each other in such a way that similar panels can be fixed to one another. The mutually matching retaining profiles have complementary hook elements that can be hooked into one another and the hook elements have retaining surfaces which hold the panels against each other when the panels are mounted in such a way that a gap-free surface is obtained.

  • Patent number: 7856789
    Abstract: The method for laying and interlocking the panels uses panels with complementary, formfitting retaining profiles extending over the length of the sides. The complementary edges of the panels allow two adjacent panels to be positively joined such that displacement of the panels away from one another is prevented, while enabling articulation of the panels with respect to one another at the joint location. The method of installation provides for installing a new panel to a first row and a panel in a second row by first joining the new panel to the panel of the second row at its short side, followed by pivoting the new panel upwards out of the plane of the laid panels along its long side, along with at least the adjacent end of the first panel in the second row, into an inclined position, and sliding the new panel into the retaining profile of the panels in the first row. The new panel and the raised end of the panel in the second row are then pivoted down into the plane of the laid panels.

  • Publication number: 20090199502
    Abstract: A fastening system for rectangular slab-like panels having two long edges and two short edges and including retaining profiles arranged on the edges, of which oppositely arranged retaining profiles match one another in such a way that identical panels can be connected to one another. The retaining profiles in a connected state produce a form fit in a direction which extends perpendicularly to a laying plane in which the panels are to be laid, and/or produce a form fit in a direction which lies in the laying plane and extends perpendicularly to the connected edges. The retaining profiles have on the long edges and/or on the short edges at least one surface which interacts with a complementary surface when the retaining profiles are connected to one another.

  • Publication number: 20070245670
    Abstract: The invention relates to a panel and a locking system for panels with edge profiles provided on at least two opposite edges of the panels for the positive connection of similar panels, including an edge profile designed as a groove profile, with an upper groove wall and a lower groove wall, and an edge profile designed as a tongue profile, with a notch projection on the underside of the tongue that engages a notch recess in a the lower groove wall on an adjacent panel in the assembled state, where the engaged edge profiles form an articulated joint that acts to restore the panels to their installation plane when deflected either up or down, where the upper groove wall has a flank on the inside that opens towards the free end of the groove wall.

  • Patent number: 6568148
    Abstract: The present disclosure involves a covering element for building surfaces and a method for the production thereof. The covering element includes a decorative visible side generally having a support plate having top and bottom surfaces, an upper transparent face sheet bonded to the top surface of the support plate, and a lower face sheet bonded to the bottom surface of the support plate. The upper face sheet has a support layer having cellulose in which an abrasion-resistant material is embedded in the form of corundum particles. In the present configuration, a decorative layer is applied to the bottom of the support layer by a color printing process. The decorative layer, which is underneath the support layer, is visible after all the layers have been pressed together under the application of heat. This process causes it to become transparent. The support layer and the decorative layer are covered with bonding material having melamine resin.

  • Patent number: 6505452
    Abstract: The invention relates to a fastening system for panels whose edges are provided complementary holding profiles which match one another in such a manner that further panels can be fastened to the free edges of a previously placed panel. The holding profiles of at least the long edges are configured as complementary positive-fit profiles, one of the profiles having a projection with a convex bottom edge, and the other profile having a recess with a concave bottom edge, such that the profiles may be interconnected by a pivoting motion. Such complementary design of the profiles enables the positive-fit profiles of the long edges of two panels to form a common joint which, when the panels are laid, enables bidirectional pivoting of the panels with respect to one another about a pivot axis that is parallel to the joined long edges of the panels.
