Description
BACKGROUND

1. Technical Field

Embodiments of the present invention relate generally to floor tiles and, more particularly, but not exclusively, to a floor tile that attaches to adjacent floor tiles rather than to the underlying surface.

2. Description of Related Art

Floor tiles are a universally popular type of floor covering, and are commonly found in personal residences, business offices, and industrial locations. They are available in a myriad of styles, sizes, colors, and patterns. Floor tiles are used in almost every interior location, including garages, as well as in outdoor locations such as balconies and patios.

Most floor tiles have a finished surface that faces up, or outwards from the floor. This surface will generally have a color or pattern attractive to the user, and be sufficiently durable to be walked upon or to have furniture placed on it, while resisting wear and discoloration for an extended period of time. The tiles attach to the ground by an adhesive spread on their bottom surface.

Another type of tile attaches to adjacent tiles rather than to the ground, and creates a tile surface known as a “floating floor”. Some tiles of this type use a tongue and groove system to connect to one another. In this system, one side or edge of a tile will have a flange or tongue, and another side will have a groove. The tongue from one tile is pressed or fit into the groove of an adjacent tile, securing their connection. A floating floor tile has an advantage of being relatively easily to install, since the floor being covered does not receive an adhesive and accordingly requires less preparation.

 DETAILED DESCRIPTION

Reference will now be made in detail to embodiment(s) of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiment(s) is/are described below to explain the present invention by referring to the figures.

Referring now to FIGS. 1A and 1B, there is shown a perspective view of a floor tile 10 consistent with an embodiment of the present invention. As will be explained in greater detail below, floor tile 10 is a “floating floor” type of tile that attaches to adjacent tiles rather than to the underlying ground. FIG. 1B is a view of the tile of FIG. 1A in which the tile is inverted, or turned over to reveal an underside that is not visible in the view of FIG. 1A.

Floor tile 10 has two sections 12, each of which has a finished surface 14 and a sectional surface 16. The finished surfaces 14 and sectional surfaces 16 occupy opposing sides of their respective sections. To enhance clarity and ease of explanation, the letter suffixes “p” and “q” will be used to distinguish the two sections. Accordingly, floor tile 10 has a first section 12p having a finished surface 14p and a sectional surface 16p, and has a second section 12q having a finished surface 14q and a sectional surface 16q. In the view of FIG. 1A first section 12p is on top and second section 12q is on the bottom, and these positions are reversed in the view of FIG. 1B.

By way of non-limiting example, first finished surface 14p, visible in FIG. 1A, is shown as a woodgrain pattern, and second finished surface 14q, visible in FIG. 1B, is shown as a circle pattern. It is a feature of the floor tile of the present embodiment that the tile is reversible. As a result, either finished surface 14 can face up and be the active tile surface, with the opposing finished surface 14 facing down and in contact with the ground. It is to be appreciated that these particular patterns are non-limiting examples only. Indeed, other patterns and/or combination of colors, patterns, textures, and materials are both contemplated and possible.

As shown in FIG. 1B, the sections have the same dimensions of a length “y” and a width “x”. The sections are attached to each other back-to-back, but are offset from a flush connection, in which their respective corners would match, by a predetermined, fixed distance along their length and along their width. For greater clarity, offset distances “dx” and “dy” are shown on each of the figures. It can be seen from both figures that each section may be viewed as being offset or displaced in position relative to the other section by a distance dx along its width, or the “x” direction, and by a distance dy along its length, or the “y” direction.

It can further be seen that the offset positioning of sections 12 defines a connective edge or strip 18 around the perimeter of floor tile 10. Connective edge 18 is half on one section and half on the other, as it is the portion of each sectional surface 16 that is not covered by the opposing section. Accordingly, in FIG. 1A the portion of connective edge 18 that is on second sectional surface 16q may be easily seen as a strip along the long edge of the tile having a length y and a width dx, and a strip along the short edge of the tile having a length x and a width dy. Similarly, in FIG. 1B, the portion of connective edge 18 that is on first sectional surface 16p may be easily seen as a strip along the long edge of the tile having a length y and a width dx, and a strip along the short edge of the tile having a length x and a width dy.

For greater clarity, a dashed line 20 is drawn on the figures to indicate the hidden edge of the bottom section in that figure. It is to be appreciated that the hidden part of connective edge 18 in each figure, designated 18′, can be represented or visualized as the strip between dashed line 20 and the outer edge of the top section. In this way, the portion of connective edge 18 on sectional surface 16p may be seen as hidden connective edge 18′ in FIG. 1A, and the portion on sectional surface 16q may be seen as hidden connective edge 18′ in FIG. 1B. As a last note on terminology, due to their relative position, the portion of connective edge 18 occupying the sectional surface 16, or bottom, of a top section may be characterized as an “overhang”, while the portion occupying the sectional surface 16, or top, of a bottom section may be characterized as an “underhang”. Accordingly, hidden connective edges 18′ in FIGS. 1A and 1B are overhanging, and visible connective edges 18 may be called underhanging edges.

Floor tiles 10 can be connected to each other by first turning each tile so that the desired finished surface 14 is facing up. The tiles are placed side-by-side so that an overhanging connective edge 18 on one tile faces an underhanging connective edge 18 of the adjacent tile. The tiles are pushed together so that the connective edges 18 are flush with each other. Connective edges 18 may then be attached using an adhesive or glue as is known in the art. In some embodiments the adhesive is already placed on connective edge 18, and is shipped with a protective cover or sheet. In such cases the sheet is removed just prior to attachment of connective edges 18. In other embodiments the adhesive may be applied at the time of installation. The connected tiles 10 will form a smooth and uninterrupted floor surface.

Examples of connected tiles are shown in FIGS. 2A, 2B, and 2C. In FIG. 2A the active surface is the woodgrain pattern of finished surface 14p, and in FIG. 2B the active surface is the circle pattern of finished surface 14q. FIG. 2C shows a variation in which a circle pattern tile is sandwiched between two woodgrain pattern tiles. It is to be appreciated that in practice, some of the floor tiles 10 shown in FIGS. 2A, 2B, and 2C may be cut in length by the installer to produce a more staggered and visually pleasing appearance.

The figures also show several dashed tile outlines to show where a subsequent tile might be installed, to indicate the manner in which tiles 10 may be connected. Accordingly, tiles may be connected long side to long side, as shown by tile outline 22, short side to short side, as shown by tile outline 23, or long and short sides together, as shown by tile outline 24. Tile outline 25 also shows that a tile may be placed long side to short side.

It is to be appreciated that the dimensions of floor tile 10 may vary over a wide range while still retaining the characteristics of the present invention. The width of connective edge 18 along either dx or dy should be sufficiently large so that there is enough surface area to establish a strong and secure connection between tiles, when the adhesive is applied and the tiles are joined. The appropriate size may depend on the application. For example, a tile floor placed in a garage would have to withstand the pressure of an automobile upon it. In such a case a relatively wider connective edge may be appropriate, in order to obtain a stronger connection. By way of a non-limiting example, a tile found to be adequate in a garage floor has the dimensions of 36 inches long, 12 inches wide, and 1¼ inch wide for both dx and dy, i.e. all portions of connective edge 18. In other embodiments, dx and dy may be slightly smaller or larger, for example, 1 inch or 1½ inches in width.

The distances dy may equal dx, so that connective edge 18 is uniform all around floor tile 10. Alternatively, dy may differ from dx. By way of a non-limiting example, one may be 1¼ inches and the other 1 inch or 1½ inches. In designing a finished floor using floor tiles 10, for any two tiles that are joined, the respective overhanging and underhanging connective edges 18 preferably are substantially the same in width.

When a tile is connected long side to long side, as shown in tile outlines 22 and 24 in FIG. 2A, the connective edges 18 of the joined tiles each have the width dx. Similarly, when tiles are connected on their short sides, as shown in tile outlines 24 and 23 in FIGS. 2A and 2B respectively, the connective edges 18 of the joined tiles each have the width dy. Accordingly, when using a tile set in which dy and dx are different, these types of connections would not be a problem. However, when connecting a long side of a tile to a short side of another tile, as shown for example in tile outline 25 of FIG. 2B, the connection is between dx from one tile and dy from another. Accordingly, a tile from the same set could not be used in that case as the long edge tile against a set of previously installed short tiles. In such a case, a substitute floor tile 10 from another set could be selected whose width dx matches the width dy of the previously installed short-edge tiles.

Preferably, connected tiles have the same offset along the common joining edge so that when the tiles are attached, the respective connective edges 18 will fit over one another precisely, and the joined tiles will abut one another, leaving no gap between them. If there is a discrepancy in width there is a likelihood that a gap will occur between the tiles. For example, if one tile has connective edge 18 that is 1¼ inches wide and the adjoining tile has a connective edge that is 1⅛ inches wide, there will be a ⅛ inch gap formed.

Gaps are undesirable because they mar the appearance of the tile floor, collect dirt, and make the floor harder to clean. In some applications a gap between tiles could lead to one of the tiles becoming loose and dislodged. For example, in the case of a tile floor installed in a garage, it is common for water to fall on the floor from rain or snow coming in through an open garage door, or from a person's shoes or an automobile driven into the garage. Where the tile surface is smooth and uninterrupted by gaps, the water will eventually evaporate and be harmless. However, water that falls into a gap may present a problem to the stability of the tile floor. For example, if a car drives over the gap, the heavy weight will press the water against the side of the tile. This will place a high pressure against the tile and may weaken the tile's attachment to its adjacent tile. Alternatively, the water may be forced under the tile, where it could be prevented from evaporating and cause further problems. If the garage is in a cold environment during winter the water in the gap could freeze and turn into ice. This would cause the water to expand, which would also exert a strong force or pressure against the tiles, weakening their adhesion and potentially dislodging one or both.

Floor tile 10 of the present embodiment can be made from any material suitable for a floor tile. An example of a material that is inexpensive and in common use is vinyl. Accordingly, in some embodiments of the invention, each section 12 can be solid vinyl. The finished surfaces 14 may be, for example, a color and/or pattern applied to one surface of the section, and the opposing, non-colored surface would be the corresponding sectional surface 16.

Additionally and/or alternatively, as FIGS. 3A and 3B illustrate, instead of being composed of a single layer, each or both section 12 could have two or more layers or laminations. For example, each section could have a layer 24 made of polyvinyl chloride (pvc) and have as another layer a plastic film 26 attached to a surface of pvc layer 24. The plastic film 26 could have a hardness, durability, color, and pattern suitable for use as finished surface 14. The opposing surface, on pvc layer 24, would be sectional surface 16.

FIG. 3A shows a floor tile 10 consistent with an embodiment of the present invention in which the sections 12 have the layers described above. In this figure, the tile 10 is shown with several curves or waves along its length, to reflect the fact that most embodiments of floor tile 10 are made from soft and flexible material and are therefore inherently flexible. FIG. 3B is an enlarged view of a corner of the floor tile of FIG. 3A, showing the layers in more detail. Accordingly, FIG. 3B shows a first pvc layer 24p and first film layer 26p from first section 12p, and second pvc layer 24q and second film layer 26q from second section 12q. For greater clarity, connective edge 18, which is part of sectional layer 16q, is shown shaded in FIG. 3B.

An adequate thickness for pvc layer 24 has been found to be about 1.5 mm, or approximately 0.094 inches. Film layer 26 is relatively much thinner. Accordingly, floor tile 10 shown in FIGS. 3A and 3B is about 3 mm.

A benefit this two-layer construction in comparison to single layer construction, such as one using solid vinyl, is that it is easier to make a greater variety and more attractive patterns for finished surface 14, as film layer 26 is a more versatile medium than plain vinyl. Another benefit is that the pvc used in pvc layer 24 is a relatively stronger material than plain vinyl. For some applications, such as in the floor of a garage, where the floor tile may be exposed to extremes of temperature, water, snow, and the weight of an automobile, it is advantageous to have a tile formed from a stronger material like pvc.

Alternatively, the floor tile 10 can have more than two layers. It is to be appreciated that floor tile 10 can be designed to have as many layers with specially configured characteristics as appropriate for the application. For example, if it is desired to have a softer feel or more give in the floor, a middle foam layer may be inserted between pvc layer 24 and film layer 26.

Since floor tile 10 is reversible, and it is desirable for the tile characteristics to be the same regardless of which finished surface 14 is being used, it is preferred that sections 12 be symmetrical, that is, where each section has the same number of layers with the same physical qualities. However, in at least one embodiment of the present invention sections 12 having a different number of layers and/or layers with different qualities could also be used.

FIGS. 4A, 4B, and 4C illustrate a method of manufacturing a floor tile 10 consistent with an embodiment of the present invention. In these figures the sections 12 are shown thicker for clarity.

The method begins, as shown in FIG. 4A, by first making or obtaining the two sections 12p and 12q, where the sections are separate and unattached. An adhesive or glue 28 is applied to the bottom, or sectional surfaces 16 of each section.

FIG. 4B shows the process by which the sections are attached. Section 12p is shown oriented the same as in FIG. 4A, with finished section 14p facing upwards. Section 12q is inverted and placed across from section 12p so that sectional surfaces 16 face one another. For illustration purposes, an offset plane 30 is shown in dashed line in FIG. 4B. Offset plane 30 has the same dimensions as section 12p, but is offset from section 12p by dx and dy for the desired predetermined distances along the section's width and length. The inverted section 12q is aligned with offset plane 30 and not with section 12p. The two sections are then brought together, as indicated by arrow 32, to the point of contact, and form a permanent connection or bond upon the adhesive hardening.

FIG. 4C shows the completed floor tile 10, ready for packaging, shipment, and installation. In order to prevent uncovered adhesive 28 on connective edge 18 from drying out and becoming unusable, a protective cover or sheet 34 such as wax paper is applied to the exposed edges. At the time of installation, sheet 34 is removed and the adhesive becomes available to connect the tile as described above.

As noted, the manufacturing process is preferably sufficiently precise so that the desired widths of dx and dy for a given set of tiles is substantially uniform for the set. While dx could be either the same as dy or different from dy for a given set of tiles, the dx values of the tiles preferably substantially match one another, and the dy values preferably substantially match one another.

As the foregoing illustrates, embodiments of the present invention provide floor tiles that have, unlike conventional tiles that have only a single floor quality or finished surface, two such surfaces. For example, floor tile 10 has been shown above with a woodgrain pattern surface and a circle pattern surface. Accordingly, the same tile could be sold to users that desire either a woodgrain surface pattern or a circle surface pattern. All that would need to be done would be to turn the tile at the point of installation so that the appropriate surface faces up.

This aspect of floor tile 10 may provide cost savings for tile retailers, distributors, and installers, due to simplified logistics and improvements in inventory control. For example, a buyer may anticipate demand of about 5000 woodgrain pattern tiles and 5000 circle pattern tiles. However, the exact breakdown in any given season may be difficult, if not impossible, to know in advance. The actual demand may turn out to be, for example, 6000 woodgrain pattern tiles and 4000 circle pattern tiles. To ensure that no sales are lost, the buyer may feel compelled to order 6500 of each of the two tile types, or 13,000 tiles total. Accordingly, as a result of the inherent uncertainty in measuring demand, the buyer will incur additional costs for procurement and storage. In addition, an excess of unsold tiles of one type may result in additional carrying costs and/or heavy losses due to discounting.

By contrast, a buyer may only need to order, for example, 10,000 to 11,000 floor tiles 10 that have both types of surfaces, and be able to meet demand for both types regardless of the particular breakdown that year. Further, the risk of being stuck with a suddenly unpopular color or pattern may be reduced. Yet another benefit is that new colors or patterns could be introduced into the marketplace by placing them on the reverse side of tiles having patterns that are known to be popular. In this way, if the new tile design is unsuccessful, the tiles can still be used and not have to be returned or discarded at a loss.

Another advantage of floor tile 10 is that the section that contacts the underlying ground provides extra distance and insulation from the ground. This section may be thought of as being, in effect, a “second floor”. This aspect of the invention may be particularly beneficial for tiles that are used in garages, balconies, patios, or other locations subject to extremes of temperature or climate. As noted, repeated extremes of temperature over several seasons cause concrete to expand and contract, which may stress and break a tile placed too close to the ground. The ground-contacting section of floor tile 10 helps to dissipate or reduce the extent to which this shifting in the ground effects the top section and finished surface of the tile. As a result, floor tile 10 may last longer than a conventional tile used in that application, and/or may be able to resist breakdown entirely.

Although selected embodiment(s) of the present invention has/have been shown and described, it is to be understood that the present invention is not limited to the described embodiment(s). Instead, it is to be appreciated that changes may be made to this/these embodiment(s) without departing from the principles and spirit of the invention, the scope of which is defined by the claims and the equivalents thereof.
