A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

An interlocking modular mat having four sides has female connectors on two sides and male connectors on the other two sides so that the modular mat can interlock with an adjacent mat and its connectors. The modular mat is configured with a plurality of structures surrounding a periphery of a top portion of the mat. The plurality of structures in combination with an underside of the top portion of the mat form a cavity. A sponge insert is configured to fit in the cavity and have a height such that a portion of the sponge insert extends from a bottom side the mat body. With the sponge insert extending beyond the bottom side of the mat body, the sponge insert bottom face generally become the supporting bottom of the modular mat to provide a more cushioned feel for a mat user.

A floor mat electrical generator system for generating electricity when users walk or dance on flooring includes a plurality of mat tiles and a power collection terminal. Each mat tile comprises a mat body having a body top side, a body bottom side, a body left side, and a body right side with a male protrusion portion and a female recessed portion to engage the adjacent mat tile. A plurality of kinetic generators is coupled to the mat body. A plurality of electrical connectors is coupled to the mat body and is in operational communication with the plurality of kinetic generators and with the plurality of electrical connectors of the adjacent mat tiles. The power collection terminal comprises a connector selectively engageable with a corner mat tile of the plurality of mat tiles and a power bank to store energy generated by the plurality of kinetic generators.

A method of manufacturing a substantially flat foam floor mat is described. The raw materials for each color layer are separately mixed and heated below their foaming temperature in different batches, and separately pressed through heated rollers to form a plurality of unfoamed sheets. The temperature of the rollers are maintained within a range of 5° C. or less. Two or more unfoamed sheets from each batch are stacked together in a press and heated above their foaming temperature to permit the stacked sheets to foam, expand, and heat-weld together. The press restricts the sheets from vertical expansion while allowing horizontal expansion. Once the sheets are foamed, a series of alternating teeth and receiving slots are cut around the boundary of the mat to form an interlocking peripheral wall.

A wood block module includes: a wood block having a deck groove formed on both sides thereof longitudinally; and a deck base disposed below the wood block, on which the wood block is placed, wherein the deck base may include: a rectangular frame; a core positioned at the center of the frame; a connection bridge extending radially from the core and connecting the core and the frame; an extended part extending from the outer side of the frame in a direction orthogonal to the connection bridge; and a protruded part protruding from the end of the extended part in a direction parallel to the connection bridge and corresponding to the deck groove of the wood block.

A method is provided for manufacturing a panel that includes a substrate and a top layer provided on the substrate. The top layer may include a decor film and a transparent film. The decor film may be a printed synthetic material film chosen from the group consisting of a vinyl-based film, a polyethylene based film, a polyurethane based film, and a polypropylene film. A print may be situated on an upper side of the printed synthetic material film. The transparent film may be a thermoplastic synthetic material film the material of which is chosen from the group consisting of polyvinyl chloride, polyethylene, polyurethane, and polypropylene. The method may involve providing the decor film and the transparent film on the substrate by performing a first press treatment at an increased temperature to form a package of the substrate, the decor film, and the transparent film. The first press treatment may be performed by a calendar device or a continuous press device. A structure may be formed in the thermoplastic synthetic material that forms a surface of the package by performing a second press treatment using a press device with a structured press element at a temperature that is lower than the increased temperature.

A connectable floor tile has a flexible, top layer, a flexible, middle layer or core, and a flexible, bottom layer. The combination of the top layer and bottom layer has sidewall portions having opposed marginal perimeter portions. The sidewall portions have an interior sidewall surface that abuts the middle core. The central portion defines a land that has a support surface. A plurality of spaced-apart cleats extend upwardly to respective distal surfaces and define channels therebetween.

A modular attic walkway system for creating a walkway across attic joists which includes a plurality of attic joists each has a top face. A plurality of platforms is removably attached to the top faces such that each platform traverses between adjacent attic joists. Each of the platforms is releasably interlocked with an adjacent one of the platforms. Each platform includes a panel. The panel has a top surface, a bottom surface, and a perimeter surface which extends between the top and bottom surfaces. The perimeter surface includes a first mating edge, a second mating edge, a first lateral edge, and a second lateral edge. The first mating edge includes a tongue cutout which extends inwardly from the first mating edge toward the second mating edge. A tongue extension extends outwardly away from the second mating edge and releasably interlocks with a tongue cutout of an adjacently positioned panel.

A panel may include a substrate and a top layer provided on the substrate. The top layer may include a printed motif provided on a paper sheet and a transparent or translucent synthetic material layer. The paper sheet may be impregnated with polyurethane or polyisocyanate. The synthetic material of the transparent or translucent synthetic material layer may be polyurethane.
