Definitions

  • Embodiments of this invention generally relate to carpet tiles and other textile face modular flooring and to methods of designing modular flooring tiles having patterns and configurations that provide various aesthetic and functional benefits.
  • modules were often glued to the floor by first applying a layer of adhesive to the underlying flooring surface and then positioning the tiles on top of the adhesive.
  • adhesive typically contacts the entire surface area of the underside of the flooring modules, which increases material costs and often leads to difficultly in re-positioning the tiles if they are positioned incorrectly. This is a particular problem during installation of patterned modules that must be matched at the seams.
  • glue remains on the flooring surface and that glue sometimes retains portions of the removed tiles. The glue (and any flooring materials held by the glue) must be removed from the floor to create a smooth surface before installing new tiles. This adds both cost and time to the installation process.
  • Embodiments of the invention provide carpet tiles of varying size and/or shape within a carpet tile installation and, in some instances, use carpet tiles of different color, pattern or style.
  • carpet tiles cut from a carpet web in a standard size and shape, such as one-half square meter carpet tiles are partitioned into smaller carpet tile fractions.
  • these carpet tile fractions are used in conjunction with larger carpet tiles in a carpet tile installation.
  • these carpet tile fractions are connected to other carpet tile fractions to form a combination carpet tile that is then used in a carpet tile installation.
  • this combination carpet tile is used with other carpet tiles in the carpet tile installation.
  • carpet tile fractions are cut directly from a carpet web and are used with other carpet tiles or with carpet tiles of a different size and/or shape, also cut from a carpet web, in a carpet tile installation.

  • the use of different sized carpet tiles increases the randomness or diversity and/or improves other aspects of the appearance of the carpet tile installations.
  • Carpet tiles of different sizes and/or shapes can be formed in a variety of ways.
  • Commercial carpet tiles may be manufactured utilizing a number of techniques, but the substantial majority of such products are manufactured by tufting carpet yarns into a tufting primary using a tufting machine.
  • the fabric produced by the tufting machine is usually about six feet or two meters wide, and that fabric is referred to here as a carpet tile "web.”

  • these square tiles are then cut into smaller carpet tile fractions, including, among other possibilities, smaller rectangular, triangular and/or square tile pieces.
  • This second cutting operation can occur immediately after manufacture at the manufacturing facility, or can occur in the field during the installation process.
  • FIGs 1-2 illustrates a carpet tile installation 10 comprised of larger square carpet tiles 12 and carpet tile fractions 14 that together form an exemplary installation pattern.
  • carpet tile fractions 14 are square carpet tiles that are smaller than larger square carpet tiles 12. While this particular installation pattern provides various aesthetic and other benefits, other installation patterns may be used.
  • a larger square tile 12 such as a standard one-half square meter carpet tile, may be partitioned into carpet tile fractions and subsequently cut into carpet tile fractions 14, as shown in Figure 3B.
  • carpet tile fractions 14 are cut directly from the carpet web without first being cut into the standard, larger square carpet tile 12.
  • the larger square carpet tiles 12 and carpet tile fractions 14 may be secured to the floor and/or one another using adhesive, tape, and/or various connectors, including, but not limited to, connectors such as those disclosed in U.S. Patent No. 7,464,510 (entitled “System and Methods for Floor Covering Installation, filed December 21, 2004), the entirety of which is incorporated herein by this reference.
  • the carpet tile installation 10 illustrated in Figure 1 comprises larger square carpet tiles 12 and carpet tile fractions 14 that are connected to one another using one or more connectors 20.
  • connector 20 includes a film 22 and an adhesive layer 24 coated on one side of the film 22.
  • An optional release layer 26 is placed on top of the adhesive layer 24 to protect the underlying adhesive. In use, the release layer 26 is removed from the connector 20 to expose the adhesive layer 24.
  • the film 22 may be of any suitable material, but, to facilitate rapid flooring installations in accordance with this invention, is preferably made of a material that is relatively stiff so that a connector 20 positioned partly in contact with the underside of a tile will project beyond the edge of the tile in roughly the same plane as the underside of the tile. This facilitates proper positioning of the projecting connector portion to make appropriate contact with an adjacent tile. This is typically greater stiffness than most adhesive tapes that will significantly curl or droop down from an underside of a tile to which a portion (but not all) of a length of such adhesive tape is attached.
  • the film 22 from which connectors of this invention are made should be sufficiently flexible to facilitate handling the connectors in a roll if desired and to permit the connectors to conform to floor or tile irregularities.
  • the film 22 should also resist shrinkage, which can result in buckling of adjacent tiles, and exhibit a relatively high tensile strength to resist stretching under foot traffic and rolling loads.
  • materials that exhibit a tensile strength between 160-270 mega Pascals ("MPa") in the machine direction and 165-210 MPa in the cross- machine direction have been found particularly suitable for this application.
  • the percentage by which the material may be elongated or stretched before breaking should also be relatively high to prevent connector breakage and failure when subjected to tensile stresses.
  • the material used be capable of being stretched 120-200% of its machine direction dimension and 150-170% of its cross-machine direction dimension before breaking.
  • the connector 20 is then positioned so that the adhesive layer 24 contacts the underside of adjacent tiles (such as larger square carpet tile 12 and carpet tile fraction 14) to span the adjacent edges of the tiles and thereby connect the tiles together to form a carpet tile installation.
  • adjacent tiles such as larger square carpet tile 12 and carpet tile fraction 14
  • the tiles are assembled on a underlying flooring surface without the need to attach them to the floor surface, so that the tiles create a floor covering that "floats" on the underlying floor surface.
  • Such a connector 20, for example may be sized for use under some or all of the entirety of a carpet tile fraction (such as carpet tile fraction 14) and extending under one or more of the adjacent larger carpet tiles (such as larger square carpet tiles 12).
  • FIGS 5A and 6A illustrate a carpet tile installation 30 according other embodiments of the invention.
  • Carpet tile installation 30 is comprised of larger square carpet tiles 32 and carpet tile fractions 34 that together form an exemplary installation pattern (shown in Figure 5B).
  • carpet tile fractions 34 are carpet tiles of a triangular shape.
  • the patterns shown in Figures 5B and 6B may be repeated to form the carpet tile installation 30. While these particular installation patterns provide various aesthetic and other benefits, other installation patterns may be used.
  • a larger square tile 32 such as a standard one-half square meter carpet tile, may be cut into carpet tile fractions 34, as shown in Figure 7A.
  • carpet tile fractions 34 are cut directly from the carpet web without first being cut into the standard, larger square carpet tile 32.
  • carpet tile fractions 34 then may be connected to one another using connectors 20 to form a combination carpet tile 36.
  • These combination carpet tiles 36 may then be connected using connectors 20 to each other and/or to larger square, non-combination carpet tiles 32 in any number of patterns, such as the patterns of the carpet tile installations 30 shown in Figure 5A or Figure 6A.

  • a larger square tile such as a standard one-half square meter carpet tile, may be cut into carpet tile fractions 44, as shown in Figure 8C.
  • carpet tile fractions 44 are cut directly from the carpet web without first being cut into the standard, larger square carpet tile.
