  • Patent number: 7464510
    Abstract: Connectors for joining adjacent modular floor covering units. The connectors include a film and an adhesive layer coated on one side of the film. To install tiles using the connectors, a first tile is placed on the floor and a connector is positioned so that the adhesive layer faces upward and does not contact the floor. The connector is typically positioned so that only a portion of the adhesive layer adheres to the underside of the tile, leaving the remainder of the connector extending from the underside of the tile. Tiles are then positioned adjacent the first tile so that a portion of the connector adheres to the adjacent tiles. In this way, the connectors span adjacent tile edges. The tiles are assembled on a underlying flooring surface without the need to attach them to the floor surface. Rather, the tiles are linked to each other with the connectors, so that the tiles create a floor covering that “floats” on the under lying floor surface.

  • Publication number: 20080213529
    Abstract: Connectors for joining adjacent modular floor covering units. Embodiments of the connectors include a film and an adhesive layer coated on one side of the film. The connectors can have a conductive component that allows electrical continuity to be maintained between adjacent tiles. In yet another embodiment, the connectors can be equipped as radio frequency identification tags by including radio frequency transponders. To install tiles using the connectors, a first tile is placed on the floor and a connector is positioned so that the adhesive layer faces upward and does not contact the floor. The connector is typically positioned so that only a portion of the adhesive layer adheres to the underside of the tile, leaving the remainder of the connector extending from the underside of the tile. One or more tiles are then positioned adjacent the first tile so that a portion of the connector adheres to the adjacent tiles. In this way, the connectors span adjacent tile edges.

  • Patent number: 7316366
    Abstract: A highly mobile, compact creel that utilizes frames for holding yarn packages (or bobbins) for feeding yarn to a tufting machine. Each frame includes holders affixed to the frame for holding yarn packages facing front and back, a header attachable to the frame for directing yarn from the yarn packages to the tufting machine, and anti-static flexible tubing for leading yarn from the holders to the header. The header provides for aligning all the yarn ends in the same plane to join them to ends already threaded into the tufting machine. An optional frame overlay upright having a ring affixed thereto and strands threaded through the ring prevents yarn from upper yarn packages from falling onto tubes holding lower yarn packages causing yarn entanglement.

  • Patent number: 7297385
    Abstract: A carpet web and a method of forming a carpet web having a striped pattern and color scheme that permits carpet tiles cut from the web to be installed without regard to relative tile positions and without visibly disrupting the pattern, but rather maintaining the appearance of a broadloom web. The web pattern includes parallel stripes having varying widths and longitudinal discontinuities. The stripes are formed with at least two colors or two shades of a color. The tiles are positionally ambiguous in that they need not be located on the floor in the same position they occupied in the web for the flooring installation to exhibit the desired uniform appearance. Instead, the tiles may be shuffled and laid in any side-by-side or top-to-bottom orientation (provided that uniform rotational orientation is maintained among the tiles) with respect to adjacent tiles without looking out of place to the ordinary viewer and without emphasizing the modularity of the flooring.

  • Patent number: 7083841
    Abstract: Carpet tiles having patterns and color schemes that obviate the need to orient the tiles in a particular positional or rotational relationship relative to each other. The tiles exhibit orthogonal ambiguity, meaning that they may be laid in any side-by-side orientation with respect to adjacent tiles without looking out of place to the ordinary viewer and thereby still achieving an appearance of continuity like broadloom carpet. Each tile has patterns of shapes having some straight and curved elements. At least some of the straight elements on each tile preferably parallel a tile edge. The shapes are formed from a color or combination of colors so that adjacent shapes on each tile have at least one color in common. Furthermore, each tile has at least one color in common with every other tile, so that when the tiles are laid, the colors on adjacent tiles coordinate.

The tiles exhibit orthogonal ambiguity, meaning that they may be laid in any side-by-side orientation with respect to adjacent tiles without looking out of place to the ordinary viewer and thereby still achieving an appearance of continuity like broadloom carpet. Each tile has patterns of shapes having some straight sides and that appear to be randomly positioned but oriented with some straight sides parallel to carpet tile sides. The shapes are formed from a color or combination of colors so that adjacent shapes on each tile have at least one color in common. Furthermore, each tile has at least one color in common with every other tile, so that when the tiles are laid, the colors on adjacent tiles coordinate. All of the colors have similar intensities so that no one color will significantly stand out from the other colors.

  • Patent number: 6622443
    Abstract: A plastic trim strip for use with high pressure plastic laminate (HPL) modules or other decorative modules used on access flooring. The strip is extruded polyvinyl chloride or other polymeric or other material such as decorative metals such as brass or aluminum. The cross sectional shape of the strip is generally rectangular with a rectangular tab that: (1) protrudes from one of the narrow edges of the rectangle, (2) is thinner than the height of the strip and (3) has one surface flush with the bottom of the strip. A portion of the edge of the HPL or other floor covering with which the strip is used, and having the same shape as the tab, is router or otherwise removed from the floor covering. The protruding tab of the trim strip is then “captured” within this rabbet with or without adhesive, thereby securely engaging the trim strip when the floor covering is installed on or bonded to the access flooring structure.
