Definitions

• the invention relates to a one-piece structure which can be used to form flush and near-flush flooring transitions such as T-moldings, hard surface reducers and end moldings, between or adjacent to flooring elements.
• Hard surface floors such as wood or laminate flooring have become increasingly popular. As such, many different types of this flooring have been developed. Generally, this type of flooring is assembled by providing a plurality of similar panels. The differing types of panels that have developed, of course, may have differing widths and thicknesses. The same is true when a laminate floor (often referred to as a "floating floor") abuts another hard surface, such as a resilient surface (such as vinyl), tile or another laminate surface, a ceramic surface, or other surface, e.g., natural or engineered wood flooring.
• a laminate floor often referred to as a "floating floor”
• a resilient surface such as vinyl
• tile or another laminate surface such as a ceramic surface, or other surface, e.g., natural or engineered wood flooring.
• transition moldings are often used to create a transition between the same.
• a problem is encountered, however, when flooring materials that are dissimilar in shape or texture are used. For example, when a hard floor is placed adjacent a carpet, problems are encountered with conventional edge moldings placed therebetween. Such problems include difficulty in covering the gap that may be formed between the floorings having different height, thickness or texture.
• the invention also provides a method by which the number of moldings can be reduced while still providing all the functions necessary of different styles of transition moldings.
• the invention can include a first element to be used in an assembly for covering a gap between edges of adjacent floor elements, such as floor panels of laminate or wood, although it may also be used as a transition between a laminate panel and another type of flooring, e.g., carpet, vinyl, ceramic, and wood.
• the first element typically includes a body having at least two feet positioned along a longitudinal axis, and a first arm or member extending generally outwardly from the feet.
• the first element may include a second arm also extending generally perpendicular from the feet.
• the outward-facing surface of the first element may be formed as a single, unitary, monolithic surface that covers both the first and second arms.
• This outward- facing surface may be decorated, for example, with a laminate or a paper, such as a monochromatic or patterned decor, optionally impregnated with a resin, in order to increase its aesthetic value, or blend, to match or contrast with the floor panels.
• the outward facing surface has incorporated therein at least one material to increase its abrasion resistance, such as hard particles of silica, alumina, diamond, silicon nitride, aluminum oxide, silicon carbide and similar hard particles, preferably particles having a Moh's hardness of at least approximately 2, more preferably at least approximately 4, and most preferably at least approximately 6.
• This outward-facing surface may also be covered with other types of coverings, such as foils (such as metal, paper or thermoplastic foils), paints or a variety of other decorative elements, including, but not limited to wood veneer, ceramic, metal, vinyl or other decorative materials.
• the first element is typically formed from one of a variety of materials, such as a core covered with carpet, laminate, ceramic or wood tile, linoleum, turf, metal, paper, natural wood or veneer, vinyl, wood, ceramic or composite finish, or any type of surface covering, while the core is generally formed from one or more of wood, fiberboard, such as high density fiberboard (HDF) or medium density fiberboard (MDF), plastics, flaxboard, gypsum, high density fiber reinforced plaster, and other structural materials, such as metals or composites, and at least over a portion of the surface thereof may be covered with a foil, a plastic, a paper, a decor or a laminate to match or contrast with the first and second arms.
• HDF high density fiberboard
• MDF medium density fiberboard
• plastics flaxboard
• gypsum high density fiber reinforced plaster
• other structural materials such as metals or composites
• the assembly of the invention typically includes, in addition to the first element, two tracks, into which the feet of the first element are inserted.
• the tracks usually include a first section, designed to be installed below a flooring element, and a second or exposed section, which includes a groove, sized and shaped to receive at least one foot of the first element.
• the assembly When installed, the assembly is designed such that the at least two feet of the first element are inserted into corresponding grooves in separate tracks. As a result, an upper portion of the structure of the first element bridges the gap.
• the size and shape of the first element and the second elements are selected such that when the assembly is installed, the upper surface of the first element is coplanar with the upper surfaces of the adjacent flooring elements.
• the assembly will function to anchor the panels adjacent the assembly together, preventing separation. Effectively, the assembly, it is believed, causes the adjacent panels to "float together," as if they were physically linked directly to each other, with the track affixed only to the adjacent, or finished flooring, i.e., not to the subfloor.
• the assembly may additionally be used to cover gaps between tongue-and- groove type panels, such as glued or glueless laminate floor panels, or even other types of flooring which are secured to a subsurface.
• An adhesive such as a glue, a microballoon adhesive, contact adhesive, or chemically activated adhesive including a water-activated adhesive, may be also positioned on any of the pieces of the assembly to either hold the assembly together or in place.
• an adhesive is not necessary, but may enhance or supplement the fit and positioning of the assembly over the gap between the floor elements. Additionally, the adhesive may assist in creating a more air-tight or moisture-tight joint.
• the assembly may be used in other non-coplanar areas, such as the edge between a wall and a floor, or even between the run and rise of stairs.
• the assembly may include the first and second arms, and feet as described above, but instead of transitioning between two floor elements placed in the same plane, may form the joint between the horizontal and vertical surfaces of a single stair element.
• the inventive assembly may be used for positioning between adjacent tongue- and-groove panels; in this regard, the assembly functions as a transition molding, which provides a cover for edges of similar or dissimilar surfaces. For example, when installing floors in a home, the assembly could be used to provide an edge between a hallway and a bedroom, between a kitchen and living or bathroom, or any areas where distinct flooring is desired. Additionally, the assembly may be incorporated into differing types of flooring, such as wood, tile, linoleum, carpet, or turf.
• the invention additionally includes a new an innovative securing means used to install both the inventive moldings as described herein, as well as other moldings, such as those described by U.S. Patent Nos. 6,517,935, and 6,898,911 , and WO0240809 (each of which is herein incorporated by reference in its entirety).
• This securing means is, most often, a track or clamp which can be glued, or otherwise secured.
• the first element of the assembly can be substantially smaller, having a less visible width than conventional overlapping transitions, as disclosed by U.S. Patent No. 6,860,074, herein incorporated by reference in its entirety. Such a smaller visible width makes the flooring transition less noticeable in doorways and increases the aesthetic appeal of the smooth and overall appearance of the finished flooring when the flooring is installed through passageways from one room to another.
• the track can be affixed to the subfloor, via any method discussed herein.
• one or both of the tracks can be provided with an element which permits movement in one or more directions to permit a degree of movement between the assembly, while still maintaining the flush or near-flush configuration.
• both tracks are affixed to the subfloor, without any movement permitted. It is believed that such a configuration will cause a floating floor to "float about” the assembly, rather than have the assembly "float with” the floor.
• the assembly of the invention can be adjusted for various flooring heights and thicknesses. This feature allows for the reduction of multiple SKU's (shop-keeper units), reducing inventory, and increasing the efficient use of materials.

• Track 22, or any track disclosed herein, may also include a magnetic strip 22D, which can be adhered to the subfloor (or underlayment). Magnetic strip 22D allows track 22 to move 360°, but as long as track 22 does not move beyond the magnetic field of a similar magnet 24 affixed to the subfloor (not shown), track 22 would remain affixed to the subfloor.
• a single magnetic strip 22D can be used in combination with a thin metallic strip 22E (not shown).
• the magnetic strip 22D can be adhered to the subfloor and the thin metallic strip 22E can be fastened to the underside of the tracks 22 or visa versa, the magnetic strip 22D can be attached to the underside of the track 22 and the thin metallic strip 22E can be attached to the subfloor.
• the track 22 is made of a magnetic metal, it can be held by magnetic attraction without the need for the metallic strip 22E.
• magnetic materials e.g., small pieces of magnets iron or other magnetic materials
• magnet 24 in the form of an electromagnet, i.e, a magnet that achieves its magnetic properties when provided with an electric current, it is possible to lay the invention in place, and when it is in the correct location, electrify magnet 24, resulting in magnet 24 becoming joined to magnet 22D of track 22. In order to disassemble the molding of the invention, it is possible to de-energize magnet 24, allowing for simple and easy removal.
• the structures of the invention as described above, are typically used in the construction of a floor or at a joint between disparate floors.
• Such floors are often found in residential structures (e.g., single and multi-family houses, condominiums, townhomes, co-operatives, apartments, and lobbies of such buildings), commercial structures (e.g., retail stores, strip malls, shopping malls, office buildings, hotels, restaurants, supermarkets, banks, churches, airports and other transit stations), public structures (e.g., stadiums and arenas, schools, museums, theaters, post offices, hospitals, courthouses and other government buildings), as well as industrial structures (e.g., manufacturing plants, mills, and warehouses).
