Definitions
- interlocked flooring As a result, an interlocked floor installed wall-to-wall cannot tolerate the contraction and expansion of each of the plank or tile. Over time, a severe campering problem inevitably results.
- interlocked flooring also suffers from an increased level of noise pollution due to the noticeable space left to echo traffic sounds between the sub-floor and the interlocked floor. In removal, the interlocked flooring solutions create extra environmental burdens and incur more material and labor cost since a significant portion of it must be destroyed in order for the entire floor to be removed.
- Underlayment systems pre-glued or not, are also limited in their benefits. While eliminating the need for sub-floor preparation by acting as a medium between the new flooring material and the sub-floor, underlayment systems are in and of itself a complicated assembly. It is costly to produce, cumbersome and complicated to install. The extra labor in applying fasteners, stables, and or other forms of structural support elements to hold the flooring in place actually end up creating additional cost in the installation process. For most underlayment systems, specialized tools are also needed in the installation.
- U.S. Patent No. 6,623,840 discloses a rubber-surfaced protective flooring tile and method of manufacturing the same which provides a covering over hard floor surfaces.
- the tile consists of two layers.
- the top has a bottom surface which has voids which extend from the bottom surface towards the top surface.
- the bottom layer is of granulated rubber and has a prepolymer material that binds to the voids in the top layer during the manufacture of the tile.
- the rubber tile provides cushion on hard surfaces to minimize injury in playgrounds, factory floors, fitness rooms, and physical therapy facilities.
- U.S. Patent No. 6,129,967 discloses a system for securing brittle ceramic tiles to the sub-floor without a supporting adhesive substrate.
- a liner is used to provide structural support and an energy absorbent layer is present which allows for the tile to withstand greater forces of abrasion without breaking.
- the liner is adhered to the sub-floor and the tiles are placed inside and are anchored to the liner and an impact resistant ceramic layer.
- U.S. Patent No. 6,694,689 discloses a modular flooring system which utilizes a free-lay support base plate. Replaceable wear surface tiles fit within the base plate. The base plate allows for the maintenance of a level floor surface when placed over a preexisting worn floor and for the removal and replacement of flooring within the base plate superstructure. The composite base plate structure permits independent temporary displacement of each of the tiles.
- U.S. Patent No. 4,654,244 discloses a loose-lay and adhered to floor structure comprised of two layers of reinforced material suitable for use over stable and unstable sub-floors. The rigidity in the flooring is achieved by two layers of reinforced material sandwiching a cushion layer. Surface layers are placed on the outside of the reinforced layers. This reinforcement is designed to prevent buckling, curling and doming under a rolled load. As an alternative, the reinforcing layer may be pre-modified such that, when used to provide a surface covering the covering will have acceptable buckling characteristics.
- U.S. Patent No. 6,751 ,917 discloses a floor tile structure without an adhesive coating at the bottom.
- Each tiles surface layer and bottom layer are attached respectively on the upper and the lower surfaces of the soft double sided adhesive tape with pressure sensitivity.
- the surface layer is possibly made of rock, metal, or other hard material and the periphery is a smooth cross-section.
- Tiles are joined by placing the adhesive on the middle protruding convex layer of one tile onto the convex edge of the adjoining one and bonding the two together in the middle, leaving no need for bottom adhesion.
- U.S. Patent No. 6,751 ,912 discloses a modular interlocking tile and flooring system. Each tile is adapted to be coupled to another interlocking tile. Each tile includes a body having a playing surface and two male and two female interlocking sides. The interlocking mechanism is adapted to allow the modular interlocking tiles to connect together in a staggered fashion.
- U.S. Patent No. 6,802,159 discloses a roll-up tile system.
- the tile includes a hinge or fold line along a second axis.
- the hinges allow the multi-tile surface to be rolled up into a hollow tube from any direction along one of the axes.
- the rolled up floor panel consists of a plurality of tile panels.
- U.S. Patent No. 6,769,217 discloses an interconnecting disengageable flooring system.
- the system includes two or more flooring panels comprised of a top wear surface and a bottom surface for contact with the support structure.
- the panels have at least three edges and all edges have recesses formed therein.
- the system also comprises a connector having a base and a projection extending vertically from the base. The projection extending from the base is shaped to be received in a disengageable vertical connected fashion into the recesses of the panels.
- U.S. Patent No. 6,803,099 discloses a self-adhering surface covering having a wear surface and a pressure-sensitive adhesive layer on the lower surface of the wear surface and a barrier layer disposed on the adhesive layer.
- the surface covering has substantially no tack at about 10 psi at 140 degrees F. but has tack at about 20 psi at 75 degrees F.
- An adhesive which is substantially non-stringing may also be employed in the adhesive layer.
- the barrier layer includes substantially non-adhesive particles which have a crash resistance of at least about 10 psi while disposed on the adhesive layer.
- the method of making the self-adhering surface covering includes applying an adhesive to a substrate to from an adhesive layer having an adhesive surface, and applying a barrier layer comprising substantially non-adhesive particles to the adhesive surface to form the surface covering. The particles have a crush resistance of at least about 10 psi while disposed on the adhesive layer.
- 6,905,100 discloses an adhesive sheet strip, single-sidedly or double-sidedly pressure-sensitively adhering, redetachable by extensive stretching pulling on a grip tab in the direction of the bond plane, where the grip tab is such that it has a static frictional force F s of at least 170 cN.

- the underlayment has an upper and a lower surface and a pressure sensitive adhesive layer disposed on the upper surface and a release layer on the adhesive layer. Summary of the Invention
- the present invention relates to removable surface coverings that are a structural improvement of floor tiles, sheets, or planks, including floor tiles, sheets, and planks or sections of varying sizes and shapes and surface types including those made from polyvinyl chloride, rubber, linoleum, polymeric resins, reinforced resins, vinyl composite, or other resilient materials, carpet, stones, ceramic, metals, glass, textiles, wood, composites thereof in desired combinations, veneers thereof in desired combinations, and laminates thereof in desired combinations, all of which are hereinafter referred to as a "floor covering".
- the present invention provides a floor covering having a dual backing layer comprising a foam layer and a cured adhesive layer.
- This dual backing layer allows the floor covering to be installed directly to a sub-floor surface with only a slight application of pressure, and without any additional application of glue or underlayment systems.
- this dual backing layer-enhanced floor covering can be removed readily from the sub-floor without any glue residue or any damage done to the sub-floor or to the flooring substrate.
- that very same floor covering may be reinstalled again without losing the effectiveness of its original tack.
- a loose-lay floor covering is provided that is self-adhering, removable and relayable, otherwise referred to as, "stick, peel, stick.”
- a backing layer without moisture-release channels comprises a top layer, which is adhered to the back surface of the floor covering with an adhesive.
- the adhesive comprises a soft, resilient material, often formed from a foam, of about 0.5mm to 3.0mm in thickness.
- the backing layer without moisture-release channels also comprises a bottom layer that is composed of a curable adhesive that has undergone a curing or cross-linked process.
- the soft, resilient cushioned or foam material may be selected from the group consisting of chemical blown polyvinyl chloride plastisols/organosols, acrylics, polyurethane foams, froth foams such as polyvinyl chloride plastisol, acrylics, melt processed foams such as polyvinyl chloride, polyethylene, ethylene vinyl acetate, metallocene polyolefin's, elastomeric polyolefin copolymers.
- foams such as polyvinyl chloride, polyethylene, ethylene vinyl acetate, metallocene polyolefin's, elastomeric polyolefin copolymers.
- other soft, resilient or cushioned materials which are non-foamed may also be employed with adequate results.
- the curable adhesives should provide sufficient adhesion and slip resistance so that the floor covering may be removed from the sub- flooring and relayed elsewhere.
- rubber-type adhesives, PVC-type adhesives, acrylic adhesives, e-beam curable acrylic adhesives, vinyl acetate-type adhesives, urethane-type adhesives, and combinations thereof have been used with the present invention with adequate results.
- the curable adhesive after the curing process, may be applied onto the foam layer by a conventional coating apparatus such as a reverse roll coater, a forward roll coater, a doctor blade, an air knife, or other similar apparatus.
- the thickness of the layer is typically around 0.1mm, but can be less or more depending on the adhesive employed.
- a dual backing comprised of a foam layer and a curable adhesive
- a floor covering made of any material composition
- a curable adhesive is affixed to a floor covering made of any material composition
- a loose-lay flooring system comprising a "stick-peel-stick” capability.
- Additional features and advantages of the invention include an increase in the floor covering's evenly distributed contact with the sub-floor as a result of the embedded foam layer providing leveling adhesion.
- the foam layer also makes the floor more comfortable and warm to walk on, being more shock- absorbent and acoustically sound.
- the curable adhesive is non-stringing and non-sticky to the touch before installation and after removal so that all of its original tack remains in place after the flooring removal and even more significantly, after the removed flooring is cleaned with water or a damp cloth.
- a backing structure with moisture- release channels is provided that is similar in structure and composition to the foregoing backing structure without moisture-release channels, except that the soft, resilient, cushion or foam layer is molded so as to define a plurality of channels within its surface so as to override a layer of cured adhesive.
- This plurality of channels allows for moisture release from beneath the floor covering. They also reinforce the surface tension of the floor covering's adhesion to a sub-floor and make the floor covering only removable from the sub-floor surface with a pulling force that is directed parallel to the orientation of the channels in the foam backing layer, but un-removable when pulled with a horizontal or diagonally directed pull force.

- a floor section member 10 formed in accordance with the present invention may comprise a vinyl tile or other floor covering material of the types including, but not limited to polyvinyl chloride, rubber, linoleum, polymeric resins, reinforced resins, vinyl composite, or other resilient materials, carpet, stones, ceramic, metals, glass, textiles, wood, composites thereof in desired combinations, veneers thereof in desired combinations, and laminates thereof in desired combinations, all of which are referred to hereinafter as floor section member 10.
- a vinyl tile or other floor covering material of the types including, but not limited to polyvinyl chloride, rubber, linoleum, polymeric resins, reinforced resins, vinyl composite, or other resilient materials, carpet, stones, ceramic, metals, glass, textiles, wood, composites thereof in desired combinations, veneers thereof in desired combinations, and laminates thereof in desired combinations, all of which are referred to hereinafter as floor section member 10.
- a first embodiment of the invention shown in Figs. 1 and 2, comprises a floor section 10 without moisture-releasing channels.
- Floor section member 10 is a self-adhesive, loose-lay installed floor surface covering which may have multiple layers including an upper wear surface 11 and an internal adhesive layer 12 that secures upper wear surface 11 to a cushion material layer 13.
- Another internal adhesive layer 14 is provided by a backing coating of cured adhesive.
- Upper wear surface 11 may be made of polyvinyl chloride (PVC) or other suitable surface material.
- the present invention is applicable to other surface layers that are formed of a variety of materials, including polymeric resins, rubber, linoleum, reinforced resin, in-aid floors, all resilient flooring, carpet, stone, ceramic, wood, wood parquet, composites, veneers, and laminates or combinations thereof.
- Upper wear surface 11 can be of varying width, thickness, density and edge shape design, color, pattern, chemistry, or composition dependent on the specific material of which it is made. [0040] Upper wear surface 11 is adhered to the thin cushioned backing of cushion material layer 13 by an internal adhesive layer 12. Upper wear surface 11 is defined by its upper surface 11a, which forms the uppermost surface of floor section member 10, and its lower surface 11b, the bottommost surface of floor section member 10.
- Internal adhesive layer 12 adheres lower surface 11b to an surface 13a which is the uppermost surface of cushion material layer 13.
- Cushion material layer 13 is defined by its upper surface 13a and lower surface 13b.
- Lower surface 13b adheres to a backing coating of cured adhesive similar to internal adhesive layer 14.
- Internal adhesive layer 14 is defined by its upper surface 14a and lower surface14b, and forms the bottommost layer of floor section member 10.
- Upper wear surface 11 may comprise any type of flooring material including, but not limited to polyvinyl chloride, rubber, linoleum, polymeric resins, reinforced resins, vinyl composite, or other resilient materials, carpet, stones, ceramic, metals, glass, textiles, wood, composites thereof in desired combinations, veneers thereof in desired combinations, and laminates thereof in desired combinations thereof.
- flooring material including, but not limited to polyvinyl chloride, rubber, linoleum, polymeric resins, reinforced resins, vinyl composite, or other resilient materials, carpet, stones, ceramic, metals, glass, textiles, wood, composites thereof in desired combinations, veneers thereof in desired combinations, and laminates thereof in desired combinations thereof.
- Cushion material layer 13 often comprises a variety of soft, resilient materials including, but not limited to foamable polymers, and in particular, foam layers such as chemical blown polyvinyl chloride plastisols/organosols, acrylics, rubber foams, polyurethane foams, froth foams such as polyvinyl chloride plastisol, acrylics, melt processed foams such as polyvinyl chloride, polyethylene, ethylene vinyl acetate, metallocene polyolefins, elastomeric polyolefin copolymers. Additionally, any soft, resilient or cushioned material which is foamed or non- foamed may also be employed. The thickness of cushion material layer 13 is often about 0.5 mm to 3.0 mm.
- Cushioned material layer 13 provides for an evenly distributed contact between floor section member 10and a sub-floor. This, in-turn, significantly increases the degree of leveling adhesion of floor section member 10 onto a sub-floor, and enhances the acoustic absorption of floor section member 10 while making the finished floor more comfortable to walk on and more shock-absorbent.
- Internal adhesive layer 14 is often formed or applied as a coating of cured -adhesive that adheres onto the sub-floor with very slight pressure, but allows lifting, removal, and repositioning of floor section member 10 with its original "tack" substantially unaffected, and without glue residue or delaminating the sub-floor.
- the cured adhesive that comprises internal adhesive layer 14 may include any adhesive that is curable, including rubber- type adhesives, PVC-type adhesives, acrylic adhesives, e-beam curable acrylic adhesives, vinyl acetate-type adhesives, urethane-type adhesives and combinations thereof. Lower surface14b of internal adhesive layer 14 must provide sufficient adhesive properties to maintain floor section member 10 in place during use.
- Internal adhesive layer 14 should also be releasable so that floor section member 10 can be removed and relayed repeatedly.
- One adhesive that has been found to provide adequate results is made of modified acrylate, with a viscosity of 3000-5000 cps/25 degrees Celsius, a density of 1.0-1.1 g/cm 3 , and a curing speed greater than 10 M/min/Lamp (80Wcm "1 ) with 80% active component.
- the coating method for this particular adhesive can be either a reverse roll coater, a forward roll coater, a doctor blade, an air knife, or other similar coating apparatus.
- Lower surface 13b adheres to a backing coating of cured adhesive similar to internal adhesive layer 14.
- the criteria for the lower adhesive layer applied on the foam layer lower surface 13b, and exposed to the sub-floor, would be any curable adhesive which: (1 ) has undergone curing or cross-linked processing; (2) has initial tack that's sufficient to bond or hold the particles to the adhesive surface and maintain the back layer in contact with the sub-floor, (3) be non-stringing and relatively resistant to penetration or compression of particles, (4) about 0.03mm to 0.05mm thick average, but can be less than 0.03 mm or greater than 0.05mm depending on the adhesive used.
- Cushioned material layer 13 may have about 0.5mm to 3.0mm thickness, but could vary depending on the foam material used.
- a further embodiment of the invention comprises a floor section member 20, e.g., a floor tile, including a moisture- releasing channel layer 24.
- Floor section member 20 comprises multiple layers, including a wear surface layer 21 that forms the uppermost layer that is seen and is the contact and wear surface.
- An internal adhesive layer 22 is adhered to a lower surface 21 a of wear surface layer 21.
- a cushion material layer 23 is positioned below the wear surface layer 21 , the lowermost layer of which defines moisture-releasing channel layer 24 comprising a plurality of lands 26 located between and separating a plurality of channels 27 that are arranged in regular intervals across the bottom of floor section member 20.
- Moisture-releasing channel layer 24 is preferably formed of an adhesive layer that may be a curable, and that functions as a glue to hold floor section member 20 in place, while allowing it to be removed and relayed.
- Moisture- releasing channel layer 24 is preferably pressure-sensitive and may be formed of rubber-type adhesives, acrylic adhesives, including e-beam curable acrylic adhesives, vinyl acetate-type adhesives, urethane-type adhesives, and combinations thereof, or any other adhesives commonly used that can be curable. Moisture-releasing channel layer 24 is often pressed or embossed so as to comprise alternating lands 26 and channels 27.
- Wear surface layer 21 may be formed from polyvinyl chloride (PVC), however, the present invention can be applied under a surface layer of a variety of materials including but not limited to polyvinyl chloride, rubber, linoleum, polymeric resins, reinforced resins, vinyl composite, or other resilient materials, carpet, stones, ceramic, metals, glass, textiles, wood, composites thereof in desired combinations, veneers thereof in desired combinations, and laminates thereof in desired combinations. Wear surface layer 21 may be formed with varying width, thickness, density and edge shape design, color, chemistry, or composition, dependent on the specific material of which the surface layer is made. [0046] Wear surface layer 21 is often applied to cushion material layer 23 by internal adhesive layer 22.
- PVC polyvinyl chloride
- Wear surface layer 21 is defined by its upper surface 21a which is the uppermost contact and wear surface of sample floor section member 20 and its bottom surface 21b.
- Internal adhesive layer 22 adheres to bottom surface 21 b and surface 23a which is the uppermost surface of cushion material layer 23.
- Cushion material layer 23 often comprises a variety of ethylene vinyl acetate foam, polyethylene foam, rubber foam, polyvinyl foam or any other soft, cushioned, resilient foam materials. The thickness of cushion material layer 23 ranges between 0.5 mm and 3.0 mm, and increases floor section member 20's evenly distributed contact with the sub-floor, thereby increasing the leveling adhesion of floor section member 20 onto the sub-floor.
- Cushion material layer 23 is defined by its upper surface 23a and a lower surface 23b.
- Moisture-releasing channel layer 24 may additionally comprise a curable adhesive layer 25 that is applied or glued to lower surface 23b of cushion material layer 23.
- Moisture-releasing channel layer 24, the bottommost layer of floor section member 20 comprises a plurality of protruding lands 26 alternated with adjacent channels 27. As shown in Fig. 3 which is a bottom view of floor section member 20, lands 26 and channels 27 often extend parallel to each other for the length and width of floor section member 20. Of course, other orientations and arrangements of channels and lands yield adequate results as well.
- Moisture-releasing channel layer 24 molds to the sub-floor upon which it is laid and reinforces the surface tension of the floor section member 20's adhesion on the sub-floor. Such molding resists horizontal and diagonal pull forces and movement on the sub-floor.
- Floor section member 20 is best removed from the sub-floor with a pull parallel to the vertical structural lining on the foam backing-layer 23 because of air channels on the grids.
- Floor section member 20 remains intact and cannot be easily displaced with a horizontal or diagonal pull.
- Moisture releasing channel layer 24 allows water to evaporate from its point of contact with the sub-floor, helping to maintain the floor section member's adhesion to the sub-floor and to maintain the aesthetic value of floor section member 20. This arrangement also prevents unwanted particles from collecting and soiling floor section member 20 so as to distress the point of contact of moisture-releasing channel layer 24 with the sub-floor.
- FIG. 5 a flowchart is provided of a typical production process for a floor section member 20 in the form of a vinyl tile formed in accordance with the present invention.
- the production process follows generally conventional means of tile manufacturing either via extrusion, calendar or heat pressure lamination.
- the process may begin with a top layer that may be a polyvinyl film that may be design printed.
- the polyvinyl chloride tile is then extruded into the tile by heat lamination and the process shown in schematic 42.
- the process referenced in schematic 42 begins with a polyvinyl chloride compound mixed with calcium carbonate and processed via a Bumberly and extruded into the tile by a crushing machine.
- Schematic 43 shows the process for incorporation of the foam layer. Schematic 43 begins with a foamable material compound processed via a Bumberly, extruded, and cut to fit the tile material already produced.
- the back surface of the tile is smoothed, and an optional ultraviolet coating may be added.
- the tile is then dried with ultraviolet lighting.
- the cured adhesive is then applied onto the foam layer and followed by drying with ultraviolet lighting. The production process is then complete, and the tile is ready for packing.
