Definitions

  • the present invention relates to a resilient substrate-free surface covering element comprising interlocking means and to a surface covering comprising such elements.
  • Surface coverings are widely used to decorate floors, walls and/or ceilings of buildings or houses and they are generally used in the form of elements, strips or tiles, to be joined together, as there are easier to install.
  • plastic surface coverings are generally polymer-based coverings, which may be either multiple-layer coverings or substrate-free coverings.
  • multiple layers coverings are heterogeneous coverings and multilayer composites, generally comprising a backing layer, usually called “substrate”, and different layers made of distinctive and different composition, commonly, PVC-based or polyolefin-based layers.
  • the substrate is a non-woven or woven fabric, felt, rubber, compact or foamable resin-based layer.
  • Substrate-free surface coverings also called “homogeneous” coverings are coverings which do not comprise a backing layer or substrate. Such coverings comprise a layer of agglomerated plastic particles. They have a uniform composition across their thickness.
  • the surface covering elements are installed using glue down methods.
  • the disadvantage of using an adhesive or a glue is that there is only a very limited time to assemble the elements after applying it over the surface to cover.
  • a glue has a limited life time due to aging which results in a decrease of its adhesive strength.
  • the present invention provides a substrate-free surface covering which do not have the drawbacks of the prior art.
  • the present invention provides a substrate-free surface covering which is an alternative of the existing substrate-free surface coverings.
  • the present invention discloses a resilient substrate-free surface covering element comprising interlocking means to connect said resilient substrate-free surface covering element to another resilient substrate-free surface covering element.
  • the "substrate-free" surface covering is a surface covering comprising agglomerated particles. Said covering do not comprise a backing layer (or substrate) on which the particles are poured onto, before the agglomeration process.
  • the resilient substrate-free surface covering element comprises one or a suitable combination of any of the following characteristics:
  • the present invention further discloses a resilient substrate-free surface covering comprising at least two resilient substrate-free surface covering elements according to the invention.
  • a decorative surface covering in particular a floor covering, presents specific mechanical properties, particularly in terms of mechanical resistance, wear and indentation resistance, but also in terms of comfort, softness, sound and heat insulation.
  • the substrate-free surface covering fulfills the recommendation of the norm ISO 10581 regarding resilient floor coverings, which is incorporated by reference in the present description.
  • the substrate-free surface covering element according to the invention is a resilient element. It fulfills thus the recommendation of the norm ISO 10581.
  • the substrate-free surface covering element is a plastic element, preferably a thermoplastic element, even more preferably a polymer-based element.
  • the substrate-free surface covering element comprises agglomerated particles, preferably multicolored particles.
  • the particles are obtained by cutting or shredding a sheet made from a composition which comprises a plastic material or thermoplastic material, or a polymer-based material, for example rubber material, PVC material or polyolefin material.
  • the composition may further comprise a filler a stabilizer, an antioxidant, a matting agent, or a combination thereof.
  • a PVC-based composition may further comprise a plasticizer.
  • the composition may further comprise a pigment or a combination of pigments.
  • composition is processed to obtain a sheet of any suitable length and thickness and having a uniform colour, or a marble effect using different colours. Said sheet is then cut using any suitable cutting means into particles.
  • the particles produced from one sheet, or a plurality of sheets of different colours, have different shapes or sizes. They may be in the form of shreds, crumbs, chips, flakes, pebbles, granules or a mix thereof. They may have any suitable size and thickness.
  • the particles are deposited, or scattered, directly on a moving carrier, which is not part of the final surface covering element, preferably a band-shaped moving carrier from for example a double belt press. No bottom layer, or substrate, is used.
  • the substrate-free surface covering element according to the present invention may be then embossed using any suitable embossing device.
  • the top side of the substrate-free surface covering element, with or without embossment is coated with a varnish layer, preferably a polyurethane-based layer, and more preferably UV-curable polyurethane.
  • the substrate-free surface covering element is obtained from an intermediate product, with or without top coating, with or without embossing, which is cut into elements, tiles or strips.
  • the substrate-free surface covering element has any suitable shape. Preferably it has a quadrilateral shape, preferably a square or rectangular shape. However, the surface covering element may also have an hexagonal shape.
  • the substrate-free surface covering element comprises interlocking means, being any suitable means to couple, or join, two substrate-free surface covering elements together.
  • the interlocking means may be provided on the upper, the lower surface of the substrate-free surface covering element, on one edge, a plurality of edges of the substrate-free surface covering element, or a combination thereof.
  • the interlocking means are provided on one surface or one edge of the substrate-free surface covering element, the interlocking means being complementary to and for cooperation with interlocking means of another the substrate-free surface covering element to joint.
  • the substrate-free surface covering element comprises first interlocking means provided on one surface and second interlocking means provided on another surface, the first interlocking means being complementary to and for cooperation with said second interlocking means to form an interconnection junction.
  • the first interlocking means are provided on at least a first edge of the substrate-free surface covering element and the second interlocking means on at least a second edge of the substrate-free surface covering element.
  • the first and second edges may be either opposite or adjacent.
  • the number of edges comprising the first and/or second interlocking means may depend on the shape of the substrate-free surface covering element.
  • the first and/or second interlocking means may be provided on all or part of the length of the surface, surfaces, edge or edges of the substrate-free surface covering element.
  • first and/or second interlocking means form a finger joint junction engagement.
  • the first interlocking means comprise an upper portion of the substrate-free surface covering element extending outwardly from at least one edge of the substrate-free surface covering element
  • the second interlocking means comprising a lower portion of the substrate-free surface covering element extending outwardly from at least one other edge of the substrate-free surface covering element
  • the first and/or second interlocking means may further comprise fastening means provided either continuously or discontinuously, preferably along the entire length of the edge of the substrate-free surface covering element.
  • the fastening means be any suitable means, adhesives or fasteners, such as for example a glue, a thermal adhesive, a hook and loop fastener such as Velcro ® type system or a combination thereof.
  • the first and second interlocking means may form a tongue and groove engagement.
  • the tongue and groove engagement may have any suitable design.
  • the first and/or second interlocking means are the ones described in US3205633 , US5630304 , US20040216418 , W02006043893 , US6715253 , W0200177461 or US2009019808 , which are integrated by reference in the present description.
  • the first and second interlocking means may form a puzzle type of engagement.

  • the first and second interlocking means may be produce by any suitable method.
  • interlocking means 2 and/or 3 may be produced by cutting, laser or water jet cutting, milling, moulding, planning.
  • the production of the interlocking means reveals the underlying layers of such coverings, thus requiring to mask said layers by an supplementary decorating step.
  • the production of the interlocking means reveals no aesthetic differences due to the fact that a substrate-free surface covering element has a uniform composition across their thickness. Therefore, no supplementary decoration is needed.
  • the substrate-free surface covering element according to the invention has the advantage of having no curl, or very limited curl, in spite of being resilient.
  • the resilient substrate-free surface covering according to the invention comprises at least one substrate-free surface covering element according to the invention.
  • the substrate-free surface covering may comprise, for example, a first surface covering element comprising interlocking means are provided on only one surface or one edge to cooperate with the complementary interlocking means of a second surface covering element.
  • the second surface covering element comprise thus complementary interlocking means to cooperate with the ones of the first surface covering element, but may also comprise the same interlocking means than the one of the first surface covering element.
  • the substrate-free surface covering may comprise a plurality of surface covering elements comprising first and second interlocking means, said first interlocking means being complementary to and for cooperation with said second interlocking means.
