This disclosure generally relates to an apparatus and method for installing modular floor coverings in a non-permanent manner. More particularly, this disclosure relates to an apparatus and method for installing modular tiles without permanently adhering the tiles to the floor.
Modular floor coverings (e.g., carpet tiles) are typically installed by applying a permanent adhesive to the flooring surface and positioning the tiles on top of the adhesive. However, such methods often cause damage to the underlying flooring surface when the tile is removed. Thus, there is a need for a non-permanent means of securing tiles to one another while providing sufficient stability to withstand normal use.
This disclosure is directed generally to a connector or fastener for modular floor coverings (e.g., carpet tiles). The connector is placed between the bottom of the carpet tile and the flooring surface (or other intermediate surface, such as an underlayment or pad). The connector may be used to join adjacent tiles to one another along a seam between the tiles and/or along the peripheral edges of the tiles. The connectors maintain the tile in a removably fixed position on the flooring surface without permanently adhering (i.e., gluing) the tiles to the flooring surface.
The connector generally includes a pair of opposed faces or surfaces. The first, upper surface or face of the connector may comprise a tile-engaging layer for contacting the bottom surface of the tile. The tile-engaging layer may comprise a material that generally operative for preventing movement of the tiles relative to one another, for example, a non-permanent adhesive, a coating that provides a high coefficient of friction surface, or any combination thereof. The second, lower surface or face of the connector may comprise a floor-contacting layer. If desired, the floor-contacting layer may comprise a material that is generally operative for preventing slipping or movement of the tiles on the floor (or any intermediate layer between the floor and the tiles), such that the connector maintains the tile in position but without permanently adhering the tile to the flooring surface. Materials that may be suitable for use as the floor-contacting layer may include a low tack adhesive, a slip resistant material, or any combination thereof.
The connector may have various shapes and dimensions. In general, the connector may be shaped and dimensioned so that the connector can be used without substantially overlapping another connector. In this manner, the assembly of tiles (i.e., the adjoined tiles) may remain as level as possible for steady positioning on the flooring surface.
In one embodiment, the connector may have a major linear dimension that is approximately equal to an integer multiple of the length of the tile. In one variation of this embodiment, the connector may extend substantially along the length of the seam between two or more tiles, such that the connector underlies substantially the entire length of the seam. In another variation of this embodiment, the connector may extend along approximately one-half the length of the seam. In such an embodiment, where multiple connectors are used, a pair of adjacent connectors may collectively extend along the length of the seam.
In another embodiment, the connector may have a major linear dimension that is less than an integer multiple of the length of the tile. In such an embodiment, the connector may underlie less than the entire length of the seam, such a portion of the adjacent tiles may remain separate from one another (i.e., adjacent to, but unconnected to one another).
In one particular exemplary embodiment, the connector includes at least one end having a substantially right isosceles triangular shape. The end may be adapted to substantially fittedly abut at least one another connector along an adjacent perpendicular seam between tiles, where needed.
Other features, aspects, and embodiments will be apparent from the following description and accompanying figures.
The description refers to the accompanying drawings, in which like reference characters refer to like parts throughout the several views, and in which:
As shown in
Viewing
A tile-engaging layer 108 may overlie or be disposed on a first side of the substrate 106. The outermost surface of tile-engaging layer 108 may define the first side or surface 102 of the connector, such that the tile-engaging layer 108 receives and/or is in contact with at least a portion of the underside or bottom of the tile. The tile-engaging layer 108 may generally comprise any suitable material operative for restricting the motion of the tile relative to the connector and to any other tile that the connector is in contact with (i.e., any adjoined tile).
In one embodiment, the tile-engaging layer 108 may comprise an adhesive material, for example, a medium to high tack adhesive. The adhesive material may be a substantially continuous layer (as shown), or may be a discontinuous layer (e.g., a random or non-random pattern of adhesive). The level of adhesion may be semi-permanent or non-permanent, such that the adhesive is sufficiently strong to adhere the connector 100 to the tile, but not so strong that the connector cannot be separated from the tile and/or repositioned without destruction or delamination of the connector 100. Although numerous adhesives may be suitable, in one exemplary embodiment, the adhesive may comprise an acrylic adhesive, for example, 350 High Holding Adhesive, commercially available from 3M (Minneapolis, Minn.). The adhesive may have any suitable coat weight or thickness, for example, from about 0.25 mil to about 3 mil, for example, from about 0.7 mil to about 2 mil, for example, about 1.1 mil. However, other suitable thicknesses and ranges thereof may be used. Thus, in one exemplary embodiment, the tile connector 100 may include an uppermost (i.e., tile-engaging) layer 108 comprising about 1.1 mil acrylic adhesive, and a substrate 102 comprising an about 2 mil polyester film. However, numerous variations are contemplated.
In another embodiment, tile-engaging layer 108 may comprise a slip resistant material, for example, a non-adhesive material having a relatively high coefficient of friction. Examples of such materials include, but are not limited to, natural or synthetic polymeric coatings, for example, polyolefin coatings, natural rubber coatings, any other suitable material, or any combination thereof.
If desired, a floor-contacting layer 110 may overlie or be disposed on a second side of the substrate 106 opposite the tile-contacting layer 102. The floor-contacting layer 110 may comprise any suitable material that is operative for preventing movement of the connector 100 (and any tiles joined to the connector) on the floor. Examples of materials that may be suitable include, but are not limited to, a low-tack, non-permanent adhesive, a non-slip material (i.e., a slip resistant material) having a sufficiently high coefficient of friction (such as those described above in connection with layer 108), a protective material, any other suitable material, or any combination thereof. Alternatively, in some embodiments, layer 110 may be omitted, such that the bottom side of the substrate 106 is a floor-contacting surface of the connector 100. Thus, in another exemplary embodiment, the tile connector 100 may include an uppermost (i.e., tile-engaging) layer 108 comprising about 1.1 mil acrylic adhesive, a substrate 102 comprising an about 2 mil polyester film, and a lowermost (e.g., floor-contacting) layer 110 comprising a polymeric non-slip coating, for example, polyethylene. However, numerous variations are contemplated.
Turning now to
The tile connector 100 can have any suitable shape and dimensions. In the example illustrated in
Further, as shown in
In some embodiments, the major linear dimension (e.g., length) L of the tile connector 100 may be an integer multiple of the length of the edge of the tile for which the connector is intended for use, such that the connector generally extends along the length of at least one tile. Thus, for an about 12 by about 12 inch tile, the connector 100 may have a major linear dimension of about 12 inches, about 24 inches, about 36 inches, and so on. Where the major linear dimension is about 12 inches, the connector is dimensioned to extend substantially along the entire length of the edge of one tile. Where the major linear dimension is about 24 inches, the connector is dimensioned to extend substantially along the entire length of two tiles, and so on. As another example, for an about 18 by about 18 inch tile, the connector may have a major linear dimension of about 18 inches, about 36 inches, about 54 inches, and so on. Where the major linear dimension is about 18 inches, the connector is dimensioned to extend substantially along the entire length of the edge of one tile. Where the major linear dimension is about 36 inches, the connector is dimensioned to extend substantially along the entire length of two tiles, and so on.
The minor linear dimension (e.g., width) W of the tile connector may be selected to ensure sufficient contact with the bottom side of each tile without unnecessarily using excess materials. In general, the minor linear dimension may be less than the length or width of the tile, and in some examples, the minor linear dimension of the tile connector may be from about 2 to about 6 inches, for example, about 4 inches, such that from about 1 to about 3, for example, about 2 inches of the width of the connector underlies each tile. Thus, in one particular example, the tile connector may have a length of 18 inches and a width of about 4 inches such that the tile connector extends substantially along the entire seam between two 18 by 18 inch tiles and such that about 2 inches of the width of the tile connector underlies each tile. However, other suitable dimensions may be used.
To use the connector 100 according to one exemplary method, the optional release liner or liners 112, 114 (where present) may be separated from the top and/or bottom sides of the connector. The connector 100 then may be positioned along a seam between two adjacent tiles with the tile-engaging layer 108 facing the bottom of the tiles with the lengthwise centerline CL (
By way of example,
In the exemplary installation 124 shown in
As shown in schematic cross-sectional view in
While the weight of the tiles T1, T2, T3, T4 (and any items placed on the tiles) may provide sufficient resistance to undesired movement of the assembly 124, additional slip resistance may be provided where the connectors 100 include a floor-contacting layer 110 or surface 104 that comprises a non-slip or slip resistant material, as discussed above.
In the exemplary installations or assemblies 224, 324 shown in
It will be noted that in this and other embodiments, it may be sufficient to use a connector 200, 300 along fewer seams, for example, as illustrated in
In the assembly 424 of
In the illustrated embodiment, the major linear dimension (i.e., length) of each arm may be an integer multiple of the length of the tile T, such that each of the four arms of the connector extends substantially along the length of one tile (only one of which is labeled), while the center C of the connector generally overlies the intersecting seams between the tiles. The major linear dimensions (i.e., length and width) of the connector 400 may be an integer multiple of two times the length of one tile T, such that the connector 400 can extend along the length of two tiles. In this manner, a single connector can secure four tiles to one another.
Still other possibilities are contemplated. For example, in the assembly 524 of
As another example, in the assembly 624 of
Still countless other possibilities are contemplated. For example, while all of the illustrated connectors are symmetrical in shape, connectors having non-symmetrical shapes are contemplated. Also, numerous other regular and irregular shapes are contemplated, including squares, circles, triangles, rectangles, and countless other shapes.
