  • Patent number: 9605388
    Abstract: A detectable warning tile system has a tile base with an upper surface and a lower surface. The upper surface has a plurality of upward projections therefrom. The tile base has two side edges for alignment with corresponding side edges of other tiles, and front and rear edges. An area of the upper surface of the tile base is formed free of the detectable warnings and may include a trough into or over which a replaceable tile section may be placed. The tile base and/or replaceable tile section may be configured to receive one or more individually-installable detectable warnings.

  • Patent number: 8984840
    Abstract: A method and system for covering industrial wood plank or wood block floors that can be installed quickly without creating a hazardous environment or hazardous wastes and without the necessity of removing installed equipment. Sand is swept over the wood to fill voids and cracks. Next metal lath is stapled to the wood. A first layer of epoxy is poured onto the metal lath. After this is cured, a second coat of finish epoxy can be installed on the first epoxy layer. When this dries, the job is done and operations can be restarted, or an optional topcoat can be applied. The epoxy material used can be self-leveling for ease of application and the final floor is approximately level. The finished floor is flexible to not crack under heavy loads and to absorb shock.

  • Patent number: 8919066
    Abstract: An apparatus including an impact surface and a plurality of spaced apart stiffening columns extending from an underside of the flooring plate. The columns remain substantially rigid up to a predetermined critical pressure and then buckle as the pressure increases. The columns are at least partially surrounded by a resilient underlayment. Deflection stops may extend from the flooring plate to prevent over-buckling and/or permanent deformation of the stiffening columns. In some examples, the deflections stops may assist the floor in providing a substantially rigid surface at very high pressures.

  • Patent number: 8898972
    Abstract: A quick assembling floor mat has multiple reinforced plastic bars and multiple connecting strips. Each reinforced plastic bar has a body, a mounting seat formed on the top surface of the body, at least one metal reinforcing sheet mounted in the body to enhance the structural strength of the body and two connecting grooves respectively formed in the sidewalls of the body. Each one of the connecting strips is connected to two adjacent reinforced plastic bars and has two enlarged ends respectively formed on and protruding from the sides of the connecting strip and corresponding to the connecting grooves of the two adjacent reinforced plastic bars. The reinforced plastic bars only use a small amount of a metal material to reinforce, and this can reduce the cost of materials and can maintain the rigidity and the intensity of the quick assembling floor mat.

The mat assembly is made up of a number of structural members preferably having a “double I-beam” cross-sectional shape. Each I-beam has spaced apart flanges with edges preferably formed in tongue and groove profiles. When butted together, the tongue and grooves of adjacent I-beams mesh. Filler blocks are disposed in the cavities between the webs of the I-beams. Tension members extending through the webs and filler blocks tie multiple I-beams together to form the mat assembly. Preferably, both the I-beams and filler blocks are formed of a plastic material, via extrusion or other molding methods. The resulting mat is capable of bearing very high loads yet is decay resistant.

  • Patent number: 7303801
    Abstract: A rubber or plastic floor mat has a series of parallel upper ribs on its upper surface which define slots in which respective strips or carpeting or the like are removably held. The strips are retained along their lengths by retaining means which run continually or continuously along the slots. The strip retainers include hook-and-loop fasteners (e.g., VELCRO), and/or overhanging edges above the strip edges, preferably formed in one-piece fashion along the side of the upper ribs adjacent the slots. The overhangs may be interrupted, e.g., crenelated as seen from above, and may include bevels.

  • Patent number: 7257929
    Abstract: A module includes at least an associated two-layer structure with one first layer being a polymer base layer highly loaded with mineral fillers contributing to the rigidity of the module, and a second layer made from a printed polymer film defining the decorative part of the module, and the protection of the decorative part. An outer surface of a rigidifying base layer is designed to form a spacer means in the form of a plate of dimensions substantially greater than the format of the module, over all or part thereof, to constitute after abutment of the modules and/or edge jointing of the plate edges, a zone for receiving a sealant such as a binder, putty and like bonding.

  • Patent number: 7108902
    Abstract: A commercial floor mat has a plurality of aluminum rails arranged in closely spaced side-by-side relationship and connected together by hinged connectors beneath the rails. Each rail has a pair of downwardly facing grooves on its underside extending along respective edges of the rail. Each connector has a flexible central web and a pair of spaced upstanding tabs disposed in the downwardly facing grooves of adjacent rails. The tabs have flexible barb-shaped ribs extending along their opposed faces to anchor the tabs in the grooves with a friction fit. The flexible central webs of the connectors facilitate hinged movement of connected rails to permit the mat to be rolled onto itself into a compact configuration.

  • Patent number: 7029744
    Abstract: The present invention relates to a laminate, preferably a flooring laminate suitable for use wherever traction is needed or desired, whether due to natural or man-made conditions either indoors or outdoors. The laminate can be applied over existing flooring. The laminate includes a base layer and a traction layer including a grit material dispersed on a polymer. The base layer comprises a cured rubber blend which has been granulated to a predetermined size and subsequently rebonded with a polymeric base adhesive composition. At least some portion of the grit material of the traction layer protrudes from the polymeric composition to provide anti-slip properties.

  • Patent number: 6925766
    Abstract: There is provided a sheet material having a walking surface with high slip resistance. The sheet material has a flexible structural layer laminated to a mesh layer which has interconnected reinforced strands and protruding nodes to impart a high coefficient of friction. The high coefficient of friction of the sheet material provides a roofing underlayment which is safe to walk upon in dry, wet or dusty conditions, and on steeply sloped surfaces. The sheet material may also be used as an industrial wrapping material or a fabric.
