  • Hard surface floors such as wood (solid or engineered) or laminate flooring have become increasingly popular. As such, many different types of this flooring are assembled by providing a plurality of similar panels. The differing types of panels that have developed, of course, may have differing depths and thicknesses. The same is true when a laminate floor (often referred to as "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 wood flooring.

  • This outward-facing surface may be treated or untreated, for example, with a laminate or a paper, such as a decor, impregnated with a resin, in order to increase its aesthetic value, or blend, to match or contrast with the panels.
  • the outward facing surface has incorporated therein a 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 having a Moh's hardness of at least approximately 6.
  • This outward-facing surface may also be covered with other types of coverings, such as foils (such as paper or thermoplastic foils), paints or a variety of other decorative elements.
  • the assembly is preferably provided with a securing means to prevent the assembly from moving once assembled.
  • the securing means is a clamp or track, designed to grab the foot.
  • the clamp or rail may be joined directly to a subsurface below the floor element, such as a subfloor, by any conventional means, such as a nail, screw or adhesive.
  • a shim may also be placed between the foot and the subfloor.
  • the shim may be positioned on the underside of the clamp; however, if a clamp is not used, the shim may be positioned between the foot and the subfloor.
  • the shim may be adhered to either the foot or subfloor using an adhesive or a conventional fastener, e.g., nail or screw.
  • the assembly may also include a second molding element, for example, in the form of a leveling block or reducer positioned between at least one of the first and second arms and the adjacent floor.
  • the leveling block generally has an upper surface that is adjacent the arm, and a bottom surface that abuts against the adjacent floor when assembled.
  • the leveling block has a channel or groove formed in an upper surface, configured to receive the tab on the arm.
  • the particular size of the leveling block is often chosen to conform essentially to the difference in thicknesses between the first and second panels.
  • the exposed surfaces of the leveling block are typically formed from a variety of materials, such as a carpet, laminate flooring, ceramic or wood tile, vinyl, turf, paper, natural wood or veneer, vinyl, wood, ceramic or composite finish, or any type of covering, while the interior of the leveling block is generally formed from wood, fiberboard, such as high density fiberboard (HDF) or medium density fiberboard (MN), plastics, or other structural material, such as metals or composites, at least over a portion of the surface thereof may be covered with a paint, stain, foil, a plastic, a paper, a décor or a laminate to match or contrast with the first and second amts.
  • the leveling block additionally facilitates the use of floor coverings having varying thicknesses when covering a sub-floor.
  • the leveling block helps the molding not only cover the gap, but provide a smoother transition from one surface to another.
  • the tab when the tab is used, the tab may be positioned to slidingly engage the edge of a panel when no leveling block is used.
  • a lip may additionally be provided and positioned on the tab in order to slidingly engage a protuberance, adjacent an upper edge of the clamp, in order to retain the assembly in its installed position.
  • the tab is preferably shaped as to provide forces to maintain the assembly in the installed position.
  • the tab may be frustum-shaped, (e.g., dove-tailed) with its narrow edge proximate the arm and the wider edge furthest from the arm.
  • the tab may be lobe shaped, having a bulbous end distal from the arm.
  • only one side of the tab need be tapered (e.g., half dove-tailed).

  • the assembly may additionally he used to cover gaps between tongue-and-groove type panels, such as glue-less laminate floor panels.
  • the tab may also be designed to mate with a corresponding channel in the panel, the edge of one of the flooring elements, or may actually fit within a grooved edge.

  • an adhesive is not necessary, but may enhance or supplement the fit 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 on stairs.

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, vinyl, carpet, or turf.

  • the width of the track 11, i.e. the distance between the distinct side arms 11a, 11b corresponds to both the external dimension of the foot 7 itself and the distance between the two grooves 7,18 defined by the distance of the two adjacent side walls 19,20 of the first and second molding elements 2,3b.
  • the length of the groove 17 and/or the length of the groove 18 may be set in a manner as to compensate for a height difference between a flooring element (not shown) and the height of the second molding element 3b, as illustrated in Figs.
  • the side wall 20 of the molding element 2 may also have means for accommodating the tip of the side arm 11b of the track 11 at a partial length of the groove 7 in order to compensate for inclinations of the fixed joint cover assembly 1 according to the invention.
