Flooring system having sub-panels with complementary edge patterns

Abstract

Laminated flooring planks include decorative motifs, mechanically embossed-in-registration surface textures, recessed perimeters, and locking mechanisms. Adjacent planks substantially aligned allow embossed-in-registration patterns to be substantially continuous across adjacent flooring panels. The recessed perimeter prevents the edges of the flooring panel from prematurely wearing. Individual planks within the flooring system may comprise at least one partial sub-panel having a decorative motif and / or embossed surface texture (i.e., pattern)that is complementary with a pattern of a neighboring partial sub-panel or plank. Each plank may include edge patterns adjacent a portion of an edge of the plank and at least one bulk pattern adjacent the edge patterns. Edge patterns within a plank and of planks within a flooring system are substantially identical to each other. Bulk patterns form a substantially continuous pattern within an individual plank when adjacent a plank.

AI Technical Summary

Benefits of technology

[0019] An advantage of the present invention provides an embossed-in-registration flooring system including individual adjacent flooring planks having embossed-in-registration decorative motifs where at least one of a surface texture and decorative motif is substantially aligned between adjacent flooring planks.

[0020] Another advantage of the present invention provides an embossed-in-registration flooring system including interlocked flooring planks having embossed-in-registration decorative motifs where at least one of a surface texture and decorative motif is substantially aligned between adjacent flooring planks such that substantially continuous embossed-in-registration patterns are formed across the interlocked flooring planks.

[0021] Another advantage of the present invention provides an embossed-in-registration flooring system may, for example, include flooring planks wherein a surface of a perimeter of each individual flooring plank may be recessed such that an upper surface of the perimeter of the flooring planks is below a portion of an upper surface of the flooring planks surrounded by the perimeter.

[0022] Another advantage of the present invention provides a plank comprising a plurality of sides defining a perimeter; a plurality of edge patterns arranged proximate at least one first portion of the perimeter, wherein at least two of the plurality of edge patterns are substantially identical; and at least one bulk pattern arranged adjacent the plurality of edge patterns and proximate at least one second portion of the perimeter, wherein at least one bulk pattern and an edge pattern adjacent the at least one bulk pattern forms a substantially continuous pattern.

[0023] Another advantage of the present invention provides a flooring system, comprising at least two planks adjacent each other along a predetermined direction, wherein each plank comprises: a plurality of sides defining a perimeter; a plurality of edge patterns arranged proximate at least one first portion of the perimeter, wherein at least two of the plurality of edge patterns are substantially identical; and at least one bulk pattern arranged adjacent the plurality of edge patterns and proximate at least one second portion of the perimeter, wherein at least one bulk pattern and an edge pattern adjacent the at one least bulk pattern forms substantially continuous pattern; herein edge patterns of the at least two planks form a substantially continuous pattern.

[0024] A further advantage of the present invention provides a floor panel, comprising a plurality of sides defining a perimeter; a surface having thereon a decorative motif, said decorative motif comprising at least two edge patterns adjacent each of the sides of the panel and at least one bulk pattern in the interior of the panel and adjacent the edge pattern on each side, wherein at least one edge pattern along a side is substantially identical to the edge pattern in a corresponding position along an opposite side; and wherein at least one portion of the decorative motif along a side is substantially different from the corresponding portion of the decorative motif along an opposite side.

Problems solved by technology

However, such traditional building and finishing flooring materials tend to be expensive to produce and install.

For example, while a solid wood floor has a highly valued luxurious appearance, the materials and labor required to install such floors can be prohibitively expensive.

However, such alternatives typically do not possess the realistic look and texture of the traditional building and finishing flooring materials.

Furthermore, while high quality HPL, DPL, or CPL boards may visually look like wood, their textures readily reveal that they are not.

One problem with most alternatives to traditional building and finishing flooring materials is that their surface textures do not match their decorative motifs.

Accordingly, the attractiveness of these alternative materials is significantly reduced.

While somewhat successful, the resulting surface texture tends to lack the textual sharpness and three-dimensional characteristics of traditional materials.

While the aforementioned assembly and locking mechanisms have proven useful, they have not been used with embossed-in-registration laminate systems in which embossed-in-registration decorative motifs or graphics align across joints between the individual embossed-in-registration laminates.

Further, the aforementioned flooring systems have a relatively low ability to resist wear.

While not wishing to be bound by any particular theory, it is hypothesized that premature aging (wear) begins at or near the perimeter edges and / or along tongue and groove lines.

The perimeter of each panel, however, is substantially weaker than the center of the panel and therefore deteriorates first.

In addition, flooring systems typically do not have decorative motifs or pattern designs that are longer than the length of a plank.
