Abstract
A floor or wall covering has blocks with mating strips having multiple ridges and multiple grooves in both mating members. Ridges and grooves can have different sizes and cross-sectional shapes from one another, and can mate in a manner that provides expansion gaps. Male/female positioning pairs can advantageously be included to facilitate alignment of the blocks during installation and use. Preferred floor blocks comprise a ribbed support portion that supports a working surface, and the ribbed support portion defines a plurality of cells that collectively reduce the weight of the block by a factor of at least 20% relative to corresponding block without such cells.
Description
- This application claims the benefit of our U.S. provisional patent application with the Ser. No. 60/697,466, which was filed Jul. 7, 2005.
- The field of the invention is floor coverings.
- There is a need for modular floor covering systems that are relatively easy to install, maintain, and provide reasonably good seal against water infiltration.
- Various types of modular floor covering systems are well known, including for example systems having edges that mate using a single ridge and a single groove (see US 2002/0189183, U.S. Pat. No. 5,630,304). The known single-ridge, single-groove floor covering blocks (also called tiles) are relatively easy to install and maintain, but can come apart too easily. In addition, use of only a single ridge and a single groove on each strip provides a relatively poor water barrier.
- More sophisticated water barriers have been developed that use multiple ridges and grooves in only one of the strips, and a removable seal disposed in one of the multiple grooves. For example, Flooring Surfaces™ markets a floor covering system in which an upper edge strip mates with a lower edge strip having a separate seal. Interestingly, there do not appear to be any flooring or wall covering systems in which both mating strips have multiple ridges and multiple grooves. Thus, there is still a need for a modular floor covering system in which both mating strips have multiple ridges and multiple grooves.
- In addition, there is a long-standing problem with alignment of ridged mating systems that has never been resolved. Since any portion of a block edge can mate with any other portion of a mating block edge, larger installations frequently get out of alignment. Thus, there is still a need for systems and methods for aligning blocks having grooved mating systems.
- The present invention provides apparatus, systems and methods for covering a floor or wall surface, in which blocks have mating strips with multiple ridges and multiple grooves in both mating members.
- In one aspect of preferred embodiments, the ridges on the various strips can have different cross-sectional shapes from one another. Accordingly, the ridges on one of the strips can combine to be more massive than the ridges on the opposing strip, and the strip having the more massive ridges can be used advantageously as the upper strip. The strip having the less massive ridges can be used advantageously as the lower strip.
- In another aspect the various ridges and grooves mate in a manner that provides expansion gaps. Such gaps allow expansion room for easier assembly and disassembly.
- In yet another aspect, systems and methods are contemplated in which at least some of the blocks have both ridged mating strips and at least one mechanical positioner. Preferred positioners are male and female pairs, including for example locator and slot pairs, and boss and hole pairs. Blocks can have multiple positioners.
- Various objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.

FIG. 5C is a perspective view of a portion of the block ofFIG. 5B , having a slot that mates with the locator ofFIG. 5A . - In prior art
FIGS. 1 and 2 , a modular floor covering system 100 generally comprisesblocks edge strips Edge strip 112 has asingle ridge 115 and asingle groove 117.Edge strip 122 has tworidges grooves tubular seal 129 is disposed ingroove 127B. - In
FIGS. 3 and 4 , a floor coveringsystem 200 generally has a plurality of modular blocks. Here, edge portions ofblocks - Each block generally has four sides. In a preferred embodiment, two of the sides have edge strips arranged as
strip 212, and two other sides have edge strips arranged asstrip 222. This configuration allows identical blocks to interlock in a manner that covers a large area. Of course, other embodiments are also contemplated that have other than four sides. Thus, contemplated embodiments include those that have three sides (triangular), five sides (pentagonal), and so forth, as well as embodiments where the sides do not define a regular geometric shape. -
Floor covering block 200 generally has a thickness of at least 2 mm, preferably at least 5 mm, more preferably at least 10 mm, most preferably at least 15 mm. In preferred embodiments, block 100 is contemplated to be at least 10 cm long, more preferably at least 50 cm long, and most preferably at least 80 cm long. The modular floor covering blocks can be made of any suitable material common known for floor covering, including clay, stone, wood, polymeric materials, and especially material selected from the list consisting of vinyl, rubber, linoleum, and resin. Especially contemplated materials include PVC, DOP, polypropylene, TPR, TPE, and blends of these, along with smaller amounts of fillers and stabilizers. - Along one edge of
block 210 isedge strip 212 having twoparallel ridges 215A, 215B and grooves 217A, 217B. Asecond block 220 hasedge strip 222, with correspondingparallel grooves 227A, 227B sized and dimensioned to mate with the tworidges 215A, 215B.Edge strip 222 also has two parallel ridges, 225A, 225B, sized and dimensioned to mate with the two grooves 217A, 217B. Those skilled in the art will immediately appreciate how any number of such blocks could be configured together to make a square, rectangular or other grouping to cover a desired area of floor, lawn, wall, etc. - Edge strips can be any practical width, thickness, and length. The ridges and grooves on edge strips need not be at the lateral ends of the strips, and indeed in many cases (such as that shown in
FIGS. 3, 4 ), the most laterally positionedridge 215A can be positioned several mm from the lateral-most edge of the strip. - The two ridges of each
strip - In preferred embodiments,
ridge 225A is sized and dimensioned to abut groove 217A so as to prevent infiltration of moisture. All four of theridges top ridges 215A and 215B are larger thanbottom ridges 225A, 225B, preferably at least 5% larger, more preferably at least 15% larger, and most preferably at least 35% bigger. Bigger ridges are thought to allow relatively easier coupling of the upper and lower edge strips 220, 222, and relatively better locking performance. - With a given strip, the ridges can have same sizes as one another, or different sizes. Thus,
top ridges 215A, 215B can be the same or different sizes from one another, andbottom ridges 225A, 225B can be the same or different sizes from one another. There is a potential benefit in having different sized ridges on a given strip in that different sizes can improve the ease of coupling the strips together. To that end a more lateral ridge is preferably larger than a more medial ridge. - It is also possible, although not desirable from a manufacturing cost standpoint, for different ridges on a given strip to be made of different materials, densities, shapes, colors and so forth. In
FIGS. 3 and 4 ,ridges 215A, 215B project downwardly at angle slightly off normal, and have a laterally extendingbulbous portion 218 that acts as a lead-in region. Those features also assist in lockingstrip 212 in place when mated withstrip 222. Of course, various other shapes, sizes, and configurations of the ridges are also possible. - Further contemplated embodiments have edge strips shaped to create expansion gaps 300A-D when two blocks are installed. These expansion gaps allows relatively easier installation, relatively more aggressive snaps, and allows relatively easier disassembly. Size of the gap is defined by the distance between corresponding ridges and grooves. Preferred size of the gap is at least 0.05 mm, more preferably at least 0.5 mm, most preferably at least 1.0 mm.
- It is further contemplated that a propositioned adhesive is disposed on the strips. Such an adhesive can help in preventing water and moisture penetration through the seals, and can assist in preventing unwanted separation of mating strips.
- In
FIG. 5 , atile system 300 has a “waffle design”portion 330 that supports a main or workingsurface 350. Thewaffle design portion 330 is shown here asorthogonal ribs 332 that define substantiallysquare cells 334. In a preferred embodiment there are 20 ribs in each direction, forming 361 cells (a matrix of 19×19), but there could be a greater or lesser number of ribs in either direction. Theribs 332 can be any suitable thickness, or even have varying thicknesses, but preferably have a uniform thickness of 0.155 inch (or about 3 mm). The ribs could, of course, be oriented in some other manner, which would produce cells having a diamond, round, ovoid, or any other suitable shape. The cells can have any suitable depth, but are preferably about 4 mm deep, with a ceiling (the working surface) having a thickness of 0.063 inch (or about 2-3 mm). There can be any suitable number of cells, including especially at least 100 cells, more preferably at least 200 cells, and most preferably at least 300 cells. - It turns out that using a ribbed (“waffle design”) on the underside of a polymeric floor block provides sufficient structural integrity to support the weight of normally expected garage-based or other activity, including supporting the weight of cars, gym equipment, etc. The ribbed (“waffle design”) also provides significant cost and weight reduction. For example, use of a ribbed (“waffle design”) in place of a solid design can reduce the weight of the block by at least 20%, more preferably at least 30%, and most preferably at least 40%.
- In
FIG. 5A-5C atile system 300 includes at least two pieces ofblock 310. InFIG. 5A , block 310 has alocator 312 in the middle of one of the sides, and aboss 314 at a corner. Each of thelocator 312 andboss 314 could be placed elsewhere on theblock 310, or replaced and/or supplemented with other types, sizes, and configurations of positioners. Theboss 314, for example, could be rectangular or diamond shaped rather than round. InFIGS. 5B and 5C , aslot 322 on a first of theblocks 310, mates with thelocator 312 on a second ofblocks 310, and aring 324 defining a hole on the first ofblocks 310 that mates with theboss 314 on the second ofblockss 310. The mating pairs, (locator 312 andslot 322; andboss 314 and ring 324), serve to maintain alignment among the various blocks ofsystem 300 during installation and use. - Thus, specific embodiments and applications of plastic flooring with improved seal have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
