  • Patent number: 7401440
    Abstract: An arcuate component includes, a flexible outer board, a flexible inner board and both a first and a second plurality of arcuate tiles. Tongue and groove tracks formed along opposite longitudinal edges of the outer and inner boards lock with mating arcuate tongue-and-groove edges of the arcuate tiles which respectively span between the outer and inner boards. The arcuate tiles also preferably include at least one tongue-and-groove that spans between the outer and inner boards and that mates and locks with a tongue-and-groove formed on an immediately adjacent tile. A series of slots cut across the outer and inner boards between their longitudinal edges increases their flexibility. The mated arcuate tiles constrain the outer and inner boards into an arcuate shape. Alternatively, tongue-and-groove tracks formed along opposite longitudinal edges of a plurality of boards mate to form a cylindrically shaped arcuate architectural component such as a column.

  • Patent number: 6880307
    Abstract: The invention relates to a panel element for forming a floor covering, consisting of several identical interconnectable panel elements and having the following features: two first sides of each panel element, called the “longitudinal sides”, these sides having a groove and a tongue; the tongue of a panel element which is positioned at an angle with an installation level of a first, identical panel element can be introduced into the groove of the first panel element; the tongue interacts with the groove of the adjacent, identical panel element in such a way that two interconnected panel elements are protected against separating forces which are exerted along both of the axes extending perpendicularly to the longitudinal side of the panel elements; two second sides of the panel element, called the end sides, are provided with fixing means and a groove and tongue, these forming an end-side connection between two adjacent panel elements; the end-side grooves and tongue can be interconnected by means of the panel

  • Patent number: 6865855
    Abstract: The invention relates to flat and/or elongated building components (1, 2), preferably wooden, and a structure connecting these components (1, 2) in accordance with the groove and tongue principle. Two legs (3, 4) forming a groove (5) branch off from a front face of one of the components (1), and a tongue (6) branching off from a front face of the other component (2) can be inserted into the groove (5). Locking elements (7, 8) hold the components (1, 2) in an assembled position. In accordance with the invention, the locking elements are configured as triangular projections (7) and cavities (8) in facing or adjacent surfaces of the groove and/or tongue.

  • Patent number: 6857242
    Abstract: A cushion block for using in a build-up surface formed by strips has two male coupling devices at one end, two female coupling devices at an opposite end corresponding to the male coupling devices, a retaining device protruded from one side thereof and adapted to secure the strip to the corresponding side of the cushion block, and a deformable body connected between the male coupling devices and the female coupling device. The male and female coupling devices are so made such that multiple cushion blocks are connectable in a line in a linking direction by engaging the male coupling devices of one cushion block into the female coupling devices of another. The deformable body is deformable in the linking direction to compensate expansion of the strips due to absorption of moisture.

  • Patent number: 6851241
    Abstract: A floorboard and an openable locking system therefor comprise an undercut groove on one long side of the floorboard and a projecting tongue on the opposite long side of the floorboard. The undercut groove has a corresponding upwardly directed inner locking surface at a distance from its tip. The tongue and the undercut groove are formed to be brought together and pulled apart by a pivoting motion which has its center close to the intersection between the surface planes and the common joint plane of two adjoining floorboards.

  • Publication number: 20040250495
    Abstract: Precast concrete paver blocks are provided with interlocking edge joints so that abutting edges of adjacent paver blocks align when the blocks are installed and are maintained in alignment. At each joint, each block includes a tapered projection and a recess. When edges of two blocks are moved to abut each other, the tapered joint projection on each block enters the joint recess on the other block. The taper on the projections move the blocks to align the block surfaces. The edges of the blocks are angled or relieved below the joints to ensure a tight fit at the top of the paver blocks.

  • Publication number: 20040237446
    Abstract: A substantially planar locating device for locating tiles has a plurality of spacers upstanding from a first side of the device. The second side of the device is substantially planar for placing against a substantially planar surface. The device has a plurality of through holes extending through the device from the first side to the second side. In use, tiles can be placed against the first side of the device and be spaced apart from each other by the spacers. Adhesive can pass from the first side through the through holes to the second side to fix tiles to a surface against which the second side is placed.

  • Publication number: 20040216418
    Abstract: An interlockable panel for forming a generally planar surface. Each panel includes a first surface positioned substantially in a plane and a second surface facing opposite the first surface and substantially parallel to and displaced from the first surface. Each surface has a perimeter defined by edges extending between the first and second surfaces. The edges may include male or female edges. Each male edge includes a tongue that extends outwardly from the male edge and a longitudinally extending void that extends inwardly of the tongue. Each female edge includes a groove having a protrusion position within the groove and extending outwardly from the groove generally parallel to the first surface. An adjacent panel may be linked to a fixed panel such that the tongue engages the groove and the protrusion engages the void. The invention also includes a method for assembling a generally planar surface using interlockable panels such as the above-mentioned.
