Definitions

  • Embodiments of this invention generally relate to systems and methods for installing floor coverings, particularly including carpet tile and other modular floor coverings.
  • Floor coverings have been in use since before recorded human history. The first such materials were likely animal skins or plant materials like leaves or stems. Later, floor coverings were manufactured, such as by weaving or knotting a variety of naturally occurring fibers, including sisal and wool. Beginning in the twentieth century, such fiber-faced floor coverings began to be manufactured from man-made fibers as well.
  • modular floor coverings utilized smaller, uniform size modules or tiles in both solid surface floor coverings such as vinyl tiles and in textile-faced floor coverings, usually called carpet tiles.
  • tiles may be installed as area rugs that do not cover the entire flooring surface.
  • carpet tiles have traditionally been rectangular or square and installed in aligned rows and columns, with the edges of each tile aligned with the edges of adjacent tiles.
  • modules are not always installed in aligned rows and columns.
  • tiles are also installed in aligned columns that do not form aligned rows of modules so that a column of tiles appears shifted up or down relative to adjacent tile columns.
  • the floor covering modules are generally of relatively substantial size and weight, which facilitates maintenance of the modules in the positions they are placed when the floor covering is assembled, it is desirable to provide a means for further resisting module movement.
  • US2008 1216534 1 often leads to difficultly in re-positioning the tiles if they are positioned incorrectly.
  • adhesive remains on the flooring surface and that adhesive sometimes retains portions of the removed tiles.
  • the adhesive (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.
  • Modules may also be installed by pre-applying adhesive to the entire underside
  • adhesive may be applied in a relatively narrow strip across each module underside and covered, prior to module installation, by a plastic film or paper strip that is peeled off just before module placement. Again, however, this method involves attaching the modules directly to the floor and can result in the consequent drawbacks discussed above.
  • Modules have also be installed using double-sided adhesive tape, whereby one side of the tape is positioned on the back of the module and the other side of the tape is positioned on the floor to thereby secure the module to the floor.
  • Double-sided tape has also been positioned between and along the entirety of adjacent carpet and carpet tile edges.
  • double sided tape can be unforgiving with respect to tile repositioning and can also leave a residue on the floor upon removal of the tiles.
  • the tape has a low tensile strength and is relatively inelastic and consequently is apt to stretch and not regain its shape. This can result in the gaps between adjacent tiles.
  • modules have also been indirectly attached to the underlying flooring surface, such as with mechanical fasteners or adhesive covered pads.
  • hook and loop fasteners have been used whereby a sheet of either the hook or the loop is secured to the floor and the other of the hook or the loop is provided on the back of the modules. The hook or loop on the modules then engages the hook or loop on the floor to secure the modules to the floor.
  • Pads covered with adhesive have also been used. For example, a foam pad pre-coated on both sides with a releasable adhesive has been used. During installation, release paper or film is removed from both sides of the pad to expose the adhesive, and the pad is attached to the floor.
  • Carpet tiles are then positioned on top of the pad and held in place by the adhesive. While these systems and methods may improve the installers' ability to re-position the tiles, they significantly increase the material cost of the installation. Moreover, with these installation methods, the tiles are more likely to move relative to each other and thereby create gaps in the installation.
  • one-sided adhesive tape such as duct tape
  • US2008 1216534 1 been used to secure adjacent tiles together.
  • the tiles are positioned face down, and the tape is secured along the entirety of the adjacent edges of the tiles.
  • the tiles must then be carefully turned over to expose their wear surfaces without breaking the connection between adjacent tiles.
  • This method requires a significant amount of time to position the tape on the tiles as well as a significant material investment to tape adjacent tile edges together along the entirety of the seams.
  • adhesive tape is relatively flimsy, making it challenging to position the tape as desired on the underside of tiles, and, as with double-sided adhesive tape, suffers from low tensile strength and inelasticity, rendering it likely to permanently stretch or break when subjected to stress and thereby create permanent gaps between adjacent tiles.
  • connectors used to join adjacent floor covering units. It discloses connectors with an adhesive layer coated on one side of a film and that are positioned so that the adhesive layer faces upward and does not contact the floor. A connector can be 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, connectors can span adjacent edges of adjacent tiles. Tiles can be assembled on a underlying floor 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 underlying floor surface.
  • Connectors for joining adjacent modular floor covering units include a base or film and one or more attachment mechanisms.
  • a first tile is placed on the floor and a connector is positioned so that an attachment surface faces upward and attaches to the first tile.
  • One or more other tiles are then positioned adjacent the first tile so that the same or other attachment surface of the connector attaches to the adjacent tiles.
  • an attachment surface comprises projections that form a mechanical connection with the undersides of the tiles.
  • a connector may comprise a plastic unit with raised ridges that interact with corresponding indentations on the undersides of the tiles.
  • an attachment surface forms a connection with one or more tiles and/or the underlying floor surface by having a high coefficient of friction. Only one side of a connector can have a high coefficient of friction, or both sides of the connector (top and bottom) can provide friction.
  • Connectors may be relatively small with respect to tiles. In some cases, connectors are positioned at corners or edges at which multiple tiles abut. Connectors can be large enough to form an underlay spanning multiple tile edges, tiles, and potentially larger areas. For example, one exemplary embodiment involves a plastic underlayment sheet that covers a large portion of a flooring surface upon which multiple tiles are then placed. In other exemplary embodiments, such a plastic underlayment instead forms a grid, parallel lines, or other configuration partially covering the floor, including some or all of the locations at which tile edges will abut.
  • sheets, ribbons, and other shaped connectors may abut, overlap, and/or connect to one another in a variety of ways.
  • connector sheets may be connected to one another by tape, pads, adhesive, or otherwise.
  • a sheet or other form of connector that covers an entire flooring surface can also perform additional functions. For example, such a sheet could be used as a moisture barrier layer or cushion.
  • FIG. IA is perspective view of one embodiment of a connector.
  • FIG IB is a perspective view of a corner of a tile with an indentation for connection to the connector of FIG. 1.
  • FIG. 2 A is perspective view of another embodiment of a connector.
  • FIG 2B is a perspective view of a corner of a tile with an indentation for connection to the connector of FIG. 2.
  • FIGs 3A-3B illustrate perspective views of exemplary connectors comprising various sharp attachment members.
  • FIG 4 illustrates a side schematic view of an exemplary sharp attachment member with a barb.
  • FIG. 5 is a bottom plan view of an installation of tiles.
  • FIG. 6 is a bottom plan view of a basic unit of four tiles of the installation of FIG.
  • FIG. 7 A is a top plan view of an installation of tiles over a connector sheet.
  • FIG 7B is a side cross sectional view of a two-sided connector sheet.
  • FIG. 7C is a side cross sectional view of a three-sided connector sheet.
  • FIG. 8 is a top plan view of overlapping connector sheets.
  • FIG. 9 is a top plan view of strip connectors.
  • tiles may be of various colors and textures in a range of sizes and shapes.
  • individual tiles may be in a shape that simulates wood planking or shapes of ceramic and other tiles, including, but not limited to, hexagons, squares, rectangles, triangles and other shapes.
  • the tiles may be provided in a variety of textures.
  • Tiles may be conventional carpet tile with textile faces (including, but not limited to, tufted, bonded, and printed faces), but could also be other materials, including woven and non-woven textile flooring, solid vinyl, ceramics, leather, or any other suitable material.
  • the tiles are preferably installed on a generally smooth surface, including, but not limited to plywood, laminates, linoleum, vinyl tile, hardwoods, and concrete.
  • the tiles may be installed on an intermediate substrate, including pad and carpet, located between the tiles and the underlying floor.
  • Connectors need not connect to the underlying floor surface and thus can be used to create a floor covering that "floats" on that underlying floor surface. Connectors need not be positioned along the entirety of the adjacent edges nor even across all adjacent tiles edges in the installation. Rather, the connectors can be sized so that, when positioned in the installation, they do not extend along the entire length of the adjacent edges. Moreover, while any number of connectors may be used at any number of locations between adjacent tiles, connectors may be strategically placed in locations within the assembly (such as at some of the corners at which four square tiles meet). The releasable nature of the connectors of certain embodiments allows tiles to be easily re-positioned or replaced. Furthermore, in cases where the tiles do not interact with the underlying floor, they are easily removable, without injuring the underlying floor or leaving residue upon such removal.
  • FIG. IA illustrates one embodiment of a connector 10.
  • the connector 10 includes a base 12 and attaching members 14 on one side.
  • the connector 10 can be positioned so that the attaching members 14 contact the underside of adjacent tiles such that the connector 10 spans the adjacent edges of the tiles and thereby connects the tiles together to form a floor covering.
  • the tiles can be 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.
  • the connector 10 and/or the tiles can be attached (for example via adhesive) to the underlying floor surface and the connector 10 can provide an additional mechanism for securing the tiles within the installation.
  • the base 12 may comprise a film of any suitable material, but, to facilitate rapid flooring installations, can be made of a material that is relatively stiff so that a connector 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 without significantly curl or droop down from an underside of a tile.
  • the base 12 can be sufficiently flexible to facilitate handling the connectors in a roll and/or to permit the connectors to conform to floor or tile irregularities.
  • the base 12 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 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.
  • Polymeric materials, paperboard and other materials including textiles and metals that are suitably stiff, thin, strong, water-resistant and inexpensive may also be used for base 12.
  • Exemplary base 12 may comprise a synthetic polymer material, such as a polyolefin, a polyamide, or a polyester, and more preferably polyethylene terephthalate (“PET”) polyester. These materials are relatively cheap, can conform to the underlying floor in use, and can resist corrosion. While not necessary, it is preferable that the film material be recyclable. [0032]

  • the size of the base 12 can depend on the size of the tiles being installed. However, as a general rule, the surface area of the base 12 can be as little as 1%, and preferably between 2- 5%, of the surface area of the tiles for which the connectors are intended to be installed. For many typical carpet tile sizes, connectors 10 can be, but do not have to be, no larger than about three inches by three inches square to conserve materials and limit expense. [0033]
  • the connectors 10 are preferably provided to the installation site as individual units already entirely or partially cut into the desired shape and size to be used in the installation.

  • a connector 10 is positioned so that the attachment member 14 faces upward away from the underlying floor.
  • the connector 10 is positioned so that only a portion of the attachment member 14 attaches to the underside of the tile, leaving the remainder of the connector 10 extending from the underside of the tile.

  • any number of connectors 10 may be used to connect adjacent tiles in an installation.
  • the connectors generally need not be positioned along the entirety of the adjacent tile edges nor even across all adjacent tile edges.
  • connectors 10 need only extend along a very limited length of some of the adjacent edges.
  • the tiles of a carpet tile installation where only 5%-10% of adjacent tile edges are stabilized with connectors 10 have been found to exhibit planar stability (measured by the cupping and/or curling of the tiles) and dimensional stability (measured by the skewing of the tiles), as well as the ability to retain their relative positions in the installation when subjected to foot traffic, rolling traffic, and stresses applied during cleaning and maintenance.

Abstract

La présente invention concerne des connecteurs destinés à joindre des unités de recouvrement adjacentes de sol modulaire. Les connecteurs comprennent une base ou une fine couche et un ou plusieurs éléments de fixation. À titre d'exemple, un connecteur peut être utilisé pour installer des carreaux, un premier carreau étant placé sur le sol et un connecteur étant positionné de façon à ce qu'un élément de fixation soit orienté vers le haut et se fixe au premier carreau. Un ou plusieurs autres carreaux sont ensuite positionnés à côté du premier carreau pour que le même élément de fixation ou d'autres éléments de fixation du connecteur se fixent aux carreaux adjacents. Selon certains modes de réalisation de la présente invention, un élément de fixation comprend des protubérances qui forment un raccordement mécanique avec les dos des carreaux. Par exemple, un connecteur peut comprendre une unité en plastique dont les rives surélevées entrent en interaction avec les indentations correspondantes aux dos des carreaux. Un connecteur peut également ou en variante former un raccordement avec des carreaux et/ou une surface de sol sous-jacente grâce à un coefficient de frottement élevé.
