Description
- This application is a continuation-in-part of PCT/JUS06/38379 filed Oct. 3, 2006, which claims the benefit of U.S. patent application Ser. No. 11/432,873 filed May 12, 2006, which claims the benefit of U.S. Provisional Application No. 60/723,578 filed Oct. 4, 2005 and to U.S. Provisional Application No. 60/733,686 filed Nov. 4, 2005. The above identified applications are each hereby incorporated by reference.
- The present invention relates to a grout member for a modular flooring assembly. More particularly, the present invention relates to a replaceable, non-bonded grout member retained in position, through functional forces, between two modular floor components.
- Installing a conventional tile floor is a complicated procedure requiring expertise and craftsmanship The process, which typically involves the use of “fill-in” grout, may require several hours or days of drying time, during which time the floor must not be used. Many of the modular flooring assemblies disclosed in the prior art have not been fully successful, due at least in part to a failure to provide a robust, flexible, serviceable grout component. As such, some prior art modular flooring systems allow tiles to shift or migrate resulting in unacceptable appearance and performance, as well as a cracking and separation of the grout from the flooring components (tiles, wood, marble slabs, etc.).
- In some instances, attempts have been made to correct for the problems inherent with conventional grout approaches by incorporating in the modular flooring assembly a grout member or component that replaces or supplements traditional fill-in grout. While the concept of a grout member that can be inserted as a unit (and presumably removed if desired) is not new, existing solutions do not adequately address such problems as: securing the grout member between flooring components; centering the grout member; and accounting, via the grout member, for the inevitable variances in gap widths that exist between two or more assembled flooring components. Fox example, in U.S. patent application Ser. No. 10/752,591 to Pepa, “Paving System for Floor Tiles” (herein after “Pepa”), a number of various grout member solutions are disclosed. In each instance, the problems identified above are not resolved. More specifically, while Pepa discloses a grout member that may be inserted in the gap between tiles, assembly often requires the grout be inserted into a slot that is integral to one of two intersecting flooring components lying the grout to the flooring component in this manner invariably results in movement of the grout. The grout moves as the flooring component moves, and prevents the grout from being properly centered between tiles. Further, the solutions proposed in Pepa and others do not adequately account for variances in gap widths between adjoining components/tiles. Stated differently, existing grout systems are typically singular in size (width), and cannot easily or securely fit into gaps of varying width. While the grout solutions of the prior art may be slightly compressed and “stuffed” into a gap which would otherwise be too small, this “stop gap” approach does not address expansion and contraction depending on the gap width.
- Other grout solutions, that do not necessarily tie the grout member to a flooring component, still fall short of expectations and needs. Certain prior art systems have “sealing lips” or “beads” to help prevent the leakage of moisture and/or adhesives into the flooring substrate. These designs, however, do not provide adequate flexibility and expansion/compression to allow for gap width variations. Therefore moisture contamination and unwanted adhesion are still a possibility Likewise, current systems do not provide a reliable means to secure the grout member in the gap through spring-like or functional forces.
- As such, there is a need for a flexible, removable grout member that overcomes the limitations outlined above
- The methods and systems herein disclosed advance the art and overcome problems articulated above by providing a modular grout member that is sufficiently flexible yet sturdy; a grout member that can easily fit into gaps of varying widths while remaining centered to present an attractive and functional interstitial seal.
- In particular, and by way of example only, according to an embodiment, provided is a grout member, including: a core having a horizontal strut interconnecting a first vertical support and a second vertical support; a surface section interfaced with the horizontal strut; a first flange extending outward from the first vertical support; and a second flange extending outward from the second vertical support, wherein the first flange and the second flange each interface with a corresponding modular flooring component to secure the grout member in position.
- In yet another embodiment, provided is a grout member, including: a wedge shaped core having a horizontal strut interconnecting a first vertical support and a second vertical support; a surface section interfaced with the horizontal strut; a first malleable, resiliently deformable flange extending outward from the first vertical support; and a second malleable, resiliently deformable flange extending outward from the second vertical support, wherein each of the core, the malleable, resiliently deformable flanges, and the surface section ate formed from a different material.
- In still yet another embodiment, provided is a method of sealing, with removable grout, a modular floor assembly, including: determining a pattern of required extended and truncated, removable grout members; cutting each removable grout member according to the pattern; inserting, in a first gap formed by at least four modular floor components, an extended, removable grout member; inserting, in a second gap formed by the at least four modular floor components, a first truncated, removable grout member; inserting in the second gap a second truncated, removable grout member; and verifying a press fit of each inserted extended and truncated, removable grout member.

The grout member is intended to fit or be installed between two adjacent floor assembly components, such as a tile, tray, frame, etc. During the installation process, the grout member is pressed into a channel between interconnected modular flooring assemblies. After installation, the grout member resembles traditional fill-in grout that is spread into the grooves between adjacent tiles. The grout member is positioned such that side members or flanges extend from a core to contact a surface of the corresponding floor assembly component The grout member may be filly formed during fabrication, may be manufactured from one or more materials, and is supplied to consumers ready for installation.
- Of note, as detailed in U.S. patent application Ser. No. 11/432,873, the modular flooring assembly may comprise a tray substrate and a floor component. The floor component may comprise tile, stone, marble, wood, or other conventional flooring materials. The floor component could be a ceramic or porcelain tile, a natural stone product like marble or granite, or could be a wooden product. In at least one embodiment, floor tile systems may also incorporate the modular grout member disclosed herein. Each tray substrate typically includes connecting members, such as tabs, which allow tray substrates to interlock using tabs from two adjacent trays. The fully assembled modular floor, complete with the grout member of the present application, provides the appearance of a conventional floor.
- Importantly, the modular floor may be assembled by individuals, who may lack the training and expertise to install a conventional floor. Also, the modular floor may be quickly disassembled without damaging the sub floor; as the grout member and the modular floor are not typically attached to the sub floor by adhesives, grout compounds, or other fastening means. Further, the grout member and the modular floor may be installed over an existing sub floor without the installation of a concrete backer board, which is commonly used in ceramic tile installation.
- The present invention, using a grout member that is not permanently integrated with a tray or tile, offers certain advantages in assembly and disassembly. Further, the consumer may choose from among many different colored grout members. A damaged grout member may be easily replaced, and the grout member may also be changed to reflect different decorating tastes.
- The modular flooring assemblies associated with the present invention may be in any number of sizes and shapes well known in the art, to include 6-inch, 6½-inch, 12-inch, 13-inch and 18-inch embodiments. They may have a square or rectangular shape. Further, combinations of flooring assemblies/tiles may be used, such as the 6-inch and 12-inch modular flooring assemblies, to provide a unique appearance. The present invention may be modified to compliment these combinations of different sized modular flooring assemblies. For each design of flooring assembly, the grout member of the present disclosure may be tailored in length to precisely align with the floor components.
- Referring now to
FIGS. 1 and 2 , a perspective and a cross-sectional view of a grout member are presented. As shown in the figures, thegrout member 100 may include a substantially horizontal section or strut 102 which interfaces with and joins two substantially vertical supports, 104 and 106 respectively. Thevertical supports horizontal strut 102 at any angle desired, typically at an angle in the range of 45° to 90° (i.e. normal to thehorizontal strut 102.). In at least one embodiment of the present application, as represented inFIGS. 1 and 2 , the angle formed by thevertical supports horizontal strut 102 is much closer to 90° than to 45°, on the order of 75°-85°. - Collectively,
horizontal strut 102, andvertical supports core 108 ofgrout member 100. As shown,core 108 may have a “wedge-shaped” design that assists in holdinggrout member 100 in place between the tray substrates, tiles, or modular flooring assemblies. In particular, as thegrout member 100 is installed between modular flooring components or assemblies, the “wedge” formed by the twovertical supports grout member 100 subsequent to its installation between the tray substrates, tiles, etc. Thecore 108 is generally formed as the hardest portion of thegrout member 100. For example, in one embodiment a polypropylene may be used to form thecore 108. - A
surface section 110 is positioned atop of thecore 108. More specifically,surface section 110 interfaces with and is secured tohorizontal strut 102. In one embodiment,surface section 110 may be formed on thecore 108 during an extrusion process. When an individual is standing on a modular floor incorporatinggrout member 100, and themember 100 is fully installed into a tray substrate or a modular floor,surface section 110 is the visible portion of themember 100. - The
surface section 110 may be manufactured from a polypropylene thermal elastomer (TPE) such as SANTOPRENE®. In one or more embodiments, the elastomer ofsurface section 110 may contain a glass filled. The glass content may be approximately 3 percent to approximately 10 percent. The glass filler simulates the feel and appearance of a sanded grout, which is a desirable cosmetic feature. The glass filler further assists in stabilizing the temperature changes in thesurface section 110 elastomer, which is an important functional feature since it reduces the expansion and contraction of the elastomer due to temperature fluctuations. Further, the elastomer may be manufactured in a variety of colors, and integrated with a variety of glass fillers, to match consumer choices in decorating. - In at least one embodiment, the
surface section 110 may be made from a thermal plastic rubber or other resiliently deformable, compressible, pliable, malleable sealing material designed to fit between the tiles or tray substrates. Thesurface section 110 may includefluted edges grout member 100 in providing the finished appearance of conventional fill-in grout. - Still referring to
FIGS. 1 and 2 ,flanges vertical support FIG. 2 ,flange 116 extends outward fromvertical support 104. Similarly,flange 118 extends outward fromvertical support 106. Theflanges FIG. 7 (flanges 700 and 702). As illustrated in greater detail inFIG. 2 , theflanges vertical supports flanges grout member 100 in position. - The
grout member 100, which includes thesurface section 110,core 108, andflanges core 108, thesurface section 110, and theflanges FIG. 2 , thecore 108 may be formed from afirst material 124, theflanges second material 126, and thesurface section 110 may be formed from a third material, 128. Thefirst material 124 forming thecore 108 may be harder than the second 126 and third 128 materials, as the core 108 forms a supporting structure. The co-extrusion process reduces manufacturing costs and provides a uniform product. - In at least one embodiment of the present disclosure,
grout member 100 forms a generally straight structure with a generally uniform cross-section throughout its entire length. Thegrout member 100 may be produced in any length practical and economical; however, standard lengths may include 8 foot lengths and 12 inch lengths, which are suitable for installing with 12 inch by 12 inch tiles. Since 8 foot lengths may be utilized, installation time is reduced as many of the grout lines in a first direction may be installed with the 8 foot lengths of thegrout member 100, while the 12 inch lengths may be installed in a second, opposite direction. As there are fewer pieces to install as compared to other embodiments, installation labor times may be reduced. - The
grout member 100 may be used with any size tile. Generally, as noted above,grout member 100 will be supplied to the customer in two lengths, an extended length, such as several feet to approximately 8 to 12 feet, and a second, truncated, length generally corresponding to the length of the tile, which may be 6-inch, 12-inch, 13-inch, 18 inch, etc. By usinggrout members 100 with the extended lengths, the finished modular floor will have less grout seams (points where two sections of grout intersect) and installation is easier, since there are less extruded grout sections to install. The extended lengths ofgrout member 100 may also be easily cut to fit with snips, heavy shears, or a light saw. - Referring now to
FIGS. 3 and 4 , a unique feature of the present disclosure is highlighted As noted above,flanges grout member 100 between two components of a modular floor (tray, flame, tile, etc.). The mechanical consequences of this element of the invention are that differences or discrepancies in the gap between modular floor components can be accommodated and accounted for while still providing a finished grout look and seal. More specifically, if the gap “b” (FIG. 4 ) between twotrays tiles FIG. 3 ) betweensimilar trays tiles flanges grout member 100 to be securely centered in each instance. Concurrently, thesurface section 110 may be compressed as well to fit within the gap presented. Stated differently,grout member 100 can account, in large part, for the mechanical tolerances that inevitably build-up during the assembly, of any modular system, despite the best designs and manufacturing techniques. By virtue of “flexible” flanges and not being tied to one Or the other modular components (e g. 300, 302, 400 or 402),grout member 100 is free to “float” and always remain centered in position. Of note, this same “flex and bend” capability offlanges grout member 100 and the two modular floor components, even if the floor component surfaces with whichgrout member 100 interfaces are not truly parallel; and (b) a greater surface area of the flange, e.g.,flange 116, contacts a surface of the modular floor assembly,e.g. tray 400, thereby providing greater frictional (mechanical) forces to hold thegrout member 100 in place. - Importantly,
grout member 100 provides several sealing surfaces to seal the grout-modular floor assembly and prevent moisture or fluids from entering the tray substrate or the modular floor. As can be appreciated by referring, for example, toFIGS. 3 and 5 , thesurface section 110FIG. 3 ) or 500 (FIG. 5 ) may form a seal pressing against the tile,e.g. tile 304 inFIG. 3 andtile 502 inFIG. 57 to form a moisture, adhesive, and dust barrier. Likewise the flange combinations (e.g. 116 and 118 in FIG. 3/506 and 508 inFIG. 5 ) also form a seal by pressing against a tile or tray,e.g. tray 510 inFIG. 5 . - Referring now to
FIGS. 5 and 6 , an alternate embodiment of the present disclosure is depicted, wherein thesurface section 500 may include extended flaps (512, 514) on either side of thesurface section 500. As shown, if the gap between modular floor components,e.g. trays extended flaps tile FIG. 6 the gap varies and is occasionally somewhat smaller than typically encountered, as if often the case with modular floors, theextended flaps top surfaces tiles - Referring once again briefly to
FIG. 7 , yet another embodiment of the present disclosure is presented. As shown,flanges surface section 708. Stated differently,flange 700 extends outward from a base ofsupport 704 whileflange 702 similarly extends outward from a base ofsupport 706. As such, theflanges flanges grout member 710 is placed into position, similar toFIGS. 4 and 6 . - In
FIG. 8 , agrout member 800 is fully installed into the gap orchannel 802 formed when two modular floor assemblies,e.g. assemblies FIG. 8 , the interlockingtabs bottom tips vertical supports grout member 800. The foundation provided by thecore 820 and the twovertical supports tabs core 820 and thevertical supports FIG. 8 , thegrout member 800 has a solid feel that does not feel spongy or soft to the touch, i.e., thegrout member 800 feels similar to a traditional fill-in grout product. The twovertical supports grout member 800 and assist in securing the position of thegrout member 800. In at least one embodiment, as shown in FIG, 8 and elsewhere, thecore 820 has a hollow region between the twovertical supports - Considering for a moment
FIG. 9 , yet another implementation of the present disclosure is presented. In many instances, the tile or other flooring used in a modular floor design may be beveled. For example, inFIG. 9 ,tile 900 has abeveled edge 902 oriented and sloping generally toward thegrout member 904. In this instance, the top ofgrout member 904 may not be positioned flush with the top surface of thetile 900, but may instead lest lower within thegap 906. Nonetheless, thesurface section 908 ofmember 904 fits flush against thetile 900 side surface, providing the necessary seal between flooring and grout. In at least one embodiment employing a beveled tile design, fill-in grout of the type well known in the art may be placed above thesurface section 908 to fully close out thegap 906. When fill-in grout is employed,grout member 904 serves to properly maintain the size and integrity of thegap 906, support the hardened fill-in grout, and minimize the amount of fill-in grout required to fill thegap 906. - Referring now to
FIG. 10 , amodular floor assembly 1000, including interconnectedmodular flooring trays tray 1008, however, it can be appreciated that all four trays 1002-1008 would typically contain a tile or other flooring component (wood, marble, etc.). For exemplary purposes, a single,extended grout member 1012 and twotruncated grout members 1014 ate 1016 are shown installed in a finished position. After the modular flooring assemblies (trays) are interconnected, a pattern is established and the required grout lengths defined. Accordingly, grout members (e.g. member 1012) are cut to length. A grout member (e.g. 1012) is installed by pressing the grout member in the gap between the modular flooring assemblies. No special tools are required. Extended and truncated grout members (e.g. 1012 and 1014) are installed in a repeating pattern until the entire floor assembly is grouted. A grout member of the present application is a fabricated structure that does not undergo a drying process or phase change during its installation. Unlike a traditional fill-in grout, the grout member is not a paste or compound that is spread between the modular flooring components, therefore installation and clean up are simplified. - As the grout members,
e.g. member 1012, are installed between modular flooring components, the flanges,e.g. flange 116 inFIG. 2 and 1018 inFIG. 10 , are forced upward, thus providing a spinning-action to hold the groutmember e.g. member 1012 in position. Importantly, in at least one embodiment as discussed above, the flanges (e.g. flange 1018) are pushing outward against an edge of the flooring component (e.g. tray 1008) while the wedge shape formed by the two vertical supports,e.g. support 1020, is pressing on a top surface of tabs attached to the trays 1002-1008. This action of anchoring thegrout member 1012 against these two different surfaces, namely the edge oftray 1008 and the tabs attached thereon (not shown), provides for the secure installation of the grout member,e.g. member 1012 At the completion of the installation, the press fit of all grout members is verified. Despite the wedge action, thegrout member 1012 may be removed from the modular floor after it is installed by a firm pulling action. - The flanges, e g,
flange 1018, preferably extend the entire length of thegrout member 1012, although a grout member with an intermittent ox discontinuous flange may also be used. The dimensions of certain embodiments of an extruded grout member (e.g. 1012, 1014, 1016) may include: (a) a surface section having a thickness of approximately 0.05 inches to approximately 0.09 inches and a width of approximately 0.2 inches to approximately 0.3 inches; (b) a core, including the two vertical supports, having a thickness of approximately 0.02 inches to approximately 0.05 inches; and (c) flanges having a width of approximately 0.1 inches to approximately 0.3 inches. These dimensions described are suitable for many applications of modular flooring; however, the dimensions may be altered by one of ordinary skill in the art practicing the invention as required for their particular tiling application. - Changes may be made in the above methods, devices and structures without departing from the scope hereof. It should thus be noted that the matter contained in the above description and/or shown in the accompanying drawings should be interpreted as illustrative and not in a limiting sense. The following claims are intended to cover all generic and specific features described herein, as well as all statements of the scope of the present method, device and structure, which, as a matter of language, might be said to fall therebetween.
